5With the development of technology, all aspects of the quality of our life have been continuously improved. For transportation purposes, cars and motorcycles are widely used as personal vehicles. The number of cars and motorcycles is constantly growing. For washing cars and motorcycles, a number of automatic washing machines are used. In these automatic car washing machines, rotating brushes are usually used. Cleaning cars with rotating brushes cannot effectively remove stains and dirt from the edges or convex and concave surfaces of the car body. Some users wash the car manually with clean water, and then remove residual water stains from the car body with a dry rag. However, cleaning a car in this way requires a lot of effort and time.

6When carrying out general cleaning, users usually expose the surface of the object to be treated with a jet of water and at the same time wipe the surface of the object with a brush or rag. When cleaning a car or building, it is necessary to expose the surface to be cleaned with a strong jet of water, and then wipe the surface with a brush or a rag. To create a strong jet of water supplied to the surface to be cleaned, usually a water hose is attached to the water tap and squeeze the end of the water hose with your fingers, directing the water ejected from the end of the hose to the surface to be cleaned. After washing the surface with a jet of water, use a brush or rag to clean the washed surface. This method of cleaning is time-consuming and requires a lot of water, and therefore does not meet the requirements of saving energy and water. In order to solve the problem of excessive waste of water resources, several projects have been created combining the use of high pressure air with a water gun to enhance the effects of a strong jet of water and control the time of water consumption in order to avoid the causes of large water losses. In FIG. eight shows a traditional spray gun with a rotating nozzle, selected as a prototype (US patent application No. 2003/0029933 A1, CL B05B 7/12, publ. 02/13/2003). The spray gun A with a rotating nozzle includes a handle A1, a T-shaped tube A2, a fluid reservoir A3 and a nozzle assembly B. The spray nozzle assembly B includes a horn-shaped tube B1 having a screw connection B11 located at one end thereof and articulated to the air supply end A4 of the T-shaped tube A2, a rotating tube C having a connecting member C1 located at one end thereof and rotationally connected to the air-supplying end A4 of the T-shaped tube A2 inside the screw connection VP, counterweights C2 mounted around the periphery of the rotating tube C, the immersion tube C3. passed through the rotating tube C and the T-shaped tube A2 and lowered into the fluid reservoir A3, and the nozzle atomizer C31 located at the end of the immersion tube C3. Upon application, the flow of compressed air from an external source of compressed air is directed through the air channel in the handle A1 and the T-shaped tube A2 into the rotating tube C. When the compressed air passes through the rotating tube C and the nozzle atomizer C31 of the immersion tube C3, the Venturi effect is created - the suction of fluid from the fluid reservoir A3 into the T-shaped tube A2 for mixing with compressed air around the nozzle atomizer C31, so that the air-liquid mixture can be pushed out of the horn-shaped tube B1 in the form of an aerosol of small droplets for use. However, in the actual application, when the rotating tube C of the spray gun A with the rotating nozzle is driven by a stream of compressed air into the horn-shaped tube B1, reaching high speed, the rotating tube C and the counterweights C2 will be 3

7rub against the inner wall of the horn-shaped tube B1, causing damage to the horn-shaped tube B1 during operation. After prolonged use, the connecting portion between the connecting element C1 of the rotating tube C and the air supply end A4 of the T-shaped tube A2 can easily break and the broken component can be ejected from the horn-shaped tube B1, resulting in an accident.

8Therefore, it is desirable to create a spray gun with a rotating nozzle, eliminating the problem of friction between the rotating nozzle and the inner wall of the horn-shaped tube, as well as the problem of the possibility of breaking the rotating tube during operation.

9Signs of a prototype coinciding with the essential features of the claimed utility model: handle, including an air intake tube connected to an external source of high pressure air for compressed air, valve seat, gas supply pipe connected to the front end of said valve seat, trigger, designed to open the specified valve seat in order to pass the flow of the specified compressed air into the specified gas supply pipe, moreover, the specified gas supply tube includes an air supply channel, communicating with said valve seat and said air intake tube, docking and connecting section, located at its outer end around the end of the specified air supply channel; T-tube fluid tank node spray nozzle in the form of a horn tube.

BRIEF DESCRIPTION OF USEFUL MODEL

11This utility model was developed based on the above circumstances. Therefore, the main objective of this utility model is to create a spray gun with a rotating nozzle, which includes a handle equipped with a gas supply pipe and a trigger, an attached pipe attached to the gas supply pipe, and a rotary jet former attached to the gas supply pipe and holding the rotating nozzle in the outlet attached tube with the possibility of its rotation. So, when the handle is exposed to the trigger to allow the flow of compressed air to enter the gas supply pipe towards the rotating nozzle, the incoming compressed air stream causes the rotating nozzle of the rotating jet former to rotate in the outlet of the attached tube.

12Preferably, the spray gun with a rotating nozzle consists of a handle that includes a trigger-operated seat

13valves and gas pipe, extending from the valve seat to the docking section, attached tube attached to the docking and connecting section of the gas supply pipe, and a rotating shaper, which includes a gas pipe connected to the docking and connecting section of the gas supply tube and in a hanging position in the accommodation cavity of the attached tube, bearing, coupling and rotating nozzle, mounted on the connecting portion of the gas conduit. When the handle is exposed to the handle, the compressed air is directed through the handle air intake tube to the gas conduit of the rotating jet former and then is pushed out of the oblique opening of the rotating nozzle, and at the same time a centrifugal force is created which causes the rotating nozzle to rotate in the outlet of the attached tube, and thus the swirling stream of compressed air is ejected from the spray gun. Also, the gas supply pipe may be provided with a lower connecting pipe for connecting the water tank, and the water supply pipe is mounted in the gas supply channel of the gas supply pipe and extends from the lower connecting pipe through the gas supply channel of the gas supply pipe of the rotational jet former into the gas storage chamber of the rotating nozzle and terminates through the water outlet end hole located in the rotating nozzle. Thus, when a swirling stream of compressed air is ejected from the annular gap in the through hole around the water outlet, the liquid stream is sucked into the lower connecting pipe of the gas supply pipe and the water supply pipe and ejected from the water outlet end of the water supply pipe, and the liquid pushed out of the water outlet end, then turns into aerosol, simultaneously compressed air is ejected from an oblique hole, making the aerosol smaller.

14Preferably, the rotary jet former consists of a gas conduit, a bearing, a coupler and a rotary nozzle. The gas conduit includes a gas conduit extending axially through its opposite front and rear ends, a connecting portion located at its end with a bearing mounted thereon, a coupling and a rotating nozzle, and a connecting end member located at its opposite end and ending in a threaded portion screwed into a screw hole in the docking and connecting section of the handle gas supply tube. The connecting portion of the gas conducting tube includes a cylindrical connecting shank of a relatively smaller external diameter extending axially forward from the end of the gas conducting tube distant with respect to the gas supply tube, and a tubular threaded rod of a relatively smaller external diameter extending axially forward from the connecting cylindrical shank. The bearing is provided with an axial bore in which a connecting cylindrical shank is inserted. The coupling includes a seating recess, rigidly connected to the outer ring of the bearing for synchronous rotation with the outer ring of the bearing, and an external thread located around the periphery of the coupling. The rotating nozzle includes an internal thread that is present on one of its surfaces and which engages with the external thread of the coupler. Also, the gas storage chamber of the rotating nozzle is made in communication with the gas conduit of the gas conduit. The oblique hole of the rotating nozzle extends obliquely from the gas storage chamber to the outside of the rotating nozzle. Thus, when the incoming stream of compressed air is directed through the gas channel of the gas pipe into the gas storage chamber of the rotating nozzle, the rotating nozzle and the coupling are rotated together with the outer ring of the bearing relative to the gas pipe, and the compressed air accumulated in the gas storage chamber is ejected from the rotating nozzles through an oblique hole.

15Preferably, the gas supply pipe is a T-shaped three-way pipe containing a lower connecting pipe located on its lower side. Further, the water tank is attached to the lower connecting pipe of the gas supply pipe and contains a liquid (such as water, detergent, soap, water wax, etc.). Further, the immersion tube is connected to the lower connection tube and inserted into the water tank to draw fluid into the lower connection tube. Further, the water supply pipe is connected to the lower connecting pipe and, having communication with the immersion pipe, is inserted into the gas supply channel of the gas supply pipe; the water supply pipe ends with a water outlet. The water outlet end of the water supply tube is inserted into the through hole in the rotating nozzle on one side relative to the oblique hole. Thus, when a swirling stream of compressed air is ejected from the annular gap in the through hole around the water outlet, the liquid stream is sucked into the lower connecting pipe of the gas supply pipe and the water supply pipe and ejected from the water outlet end of the water supply pipe, and the liquid pushed out of the water outlet end is then turned into spray can; at the same time, compressed air is ejected from the oblique opening, making the aerosol finer.

DETAILED DESCRIPTION OF A USEFUL MODEL

27In FIG. Figures 1-5 show a perspective view of a spray gun with a rotating nozzle top and front, a perspective three-dimensional image of a spray gun with a rotating nozzle with a spatial separation of parts, a perspective three-dimensional image with a spatial separation of parts of a rotating shaper of a spray gun with a rotating nozzle and a view of the gun- sectional view of a spray nozzle with a rotating nozzle. As shown, the spray gun with a rotating nozzle includes a handle 1, a connecting tube 2 and a rotating shaper 3 of the jet.

28The handle 1 comprises an air intake tube 11 on its lower side, a valve seat 12 located on its upper side, a trigger 13 and a gas supply pipe 14. The trigger 13 is designed to control the valve seat 12 to pass a stream of compressed air from an external source through the air intake tube 11. The gas supply pipe 14 is connected at its rear end to the front end of the valve seat 12 on the other side of the air intake pipe 11 and encompasses an axially extending gas supply channel 140 communicating with the valve seat 12 and the air intake pipe 11. Further, the gas supply tube 14 is provided with a docking and connecting portion 141 located at its front end opposite to the valve seat 12. The docking and connecting section 141 is a docking and connecting threaded rod 1411, protruding from the front end of the gas supply tube 14, covering a screw hole 1412, communicating with the gas supply channel 140.

29The attached tube 2 includes a docking and connecting end element 21 located at one of its ends, a docking and connecting screw hole 211 made in the docking and connecting end element 21, an expanded outlet opening 201 located at its opposite end, and provided therein axially located accommodation cavity 20 in communication with the docking and connecting screw hole 211 and the hole 201.

30The rotary jet former 3 includes a gas conduit 31, a bearing 32, a coupler 33, and a rotary nozzle 34. The gas conduit 31 includes a gas conduit extending axially through its opposite front and rear ends, a connecting end member 311 provided at the rear end, that is, a threaded portion 3111 extending axially backward from the rear end of the gas conduit 31, and a connecting portion 312, available at the front end. The connecting portion 312 includes a connecting cylindrical shank 3121, extending axially forward from the front end of the gas conduit 31, and a tubular threaded rod 3122, extending axially forward from the connecting cylindrical shank 3121. The bearing 32 is provided with an axial bore 320 into which a connecting cylindrical shank 3121 of the connecting portion 312 of the gas conduit 31 is inserted. Further, the lock nut 321 is screwed onto the tubular threaded rod 3122 to prevent the bearing 32 from falling off the connecting cylindrical shank 3121. The coupling 33 is mounted on the gas conduit 31, wherein the landing recess 330 is rigidly connected to the outer ring 322 of the bearing 32, and the outer thread 331 is located around the periphery of the coupling. The rotating nozzle 34 includes an internal thread 341, available on one side thereof and engaged with the external thread 331 of the coupler 33, a gas storage chamber 340 provided in the nozzle and extending inward from the external thread 331, and an oblique hole 342 extending obliquely forward from the gas accumulator chamber 340 outward from the rotating nozzle 34, with an eccentric arrangement.

31When assembling, attach the air intake tube 11 of handle 1 to an external source of high air pressure. In this case, the user can act on the trigger 13 of the handle 1 to control the flow of compressed air from an external source of high air pressure through the air intake tube 11. Further, the sealing ring 1413 is put on the docking and connecting threaded rod 1411 of the docking and connecting section 141 of the gas supply tube 14 of the handle 1, and then the connecting and connecting screw hole 211 of the connecting and connecting end element 21 of the attachment tube 2 is screwed onto the connecting and connecting threaded rod 1411 of the connecting and connecting section 141 of the gas supply pipe 14 and pressed against the O-ring 1413 in front of the connecting and connecting end element 21 of the auxiliary pipe 2. More than that, before fastening the docking and connecting screw hole 211 of the attachment tube 2 to the docking and connecting threaded rod 1411 of the gas supply pipe 14, the threaded portion 3111 of the connecting end member 311 of the gas conducting pipe 31 of the rotational shaper 3 of the jet is screwed into the screw hole 1412 of the connecting and connecting section 141 of the gas supply pipe 14, an attached tube 2 is placed on the front side of the gas supply tube 14 around the gas conductive tube 31, and the connecting portion 312 of the gas pipe 31 is left in the expanded outlet 201 of the extension pipe 2 in a standby state, then bearing 32, the coupling 33 and the rotating nozzle 34 can be installed on the connecting portion 312 of the gas conduit 31 and left freely rotating in the expanded outlet 201 from the outside of the accommodation cavity 20 of the extension tube 2. Thus, the handle 1, attachment tube 2 and the rotary jet former 3 are assembled to form a spray gun with a rotating nozzle in accordance with the present utility model.

32When using, connect the air intake tube 11 of the handle 1 to an external source of high air pressure (e.g. to the air compressor) and then act on the trigger 13 of the handle 1 to control the flow of compressed air from an external source of high air pressure through the air intake pipe 11 and the air supply channel 121 of the valve seat 12 into the gas supply channel 140 of the gas supply pipe 14, causing the incoming compressed air stream to pass through the docking and connecting portion 141 of the gas supply tube 14 and the gas conduit 310 of the gas conduit 31 of the rotary jet former 3 to the gas storage chamber 340 of the rotary nozzle 34 and then to pass from the gas storage chamber 340 through the nozzle opening 342 into the spray gun outer environment . At the same time, the rotating nozzle 34 and the coupling 33 begin to rotate on the outer ring 322 of the bearing 32 from the pressure of the compressed air flow through them, and thus a strong stream of air is continuously twisted and erupted on the surface of the object (car body or the exterior glazing of the building) in order to remove water Mordant or dust from the surface of the object without causing damage.

33In addition, the attachment tube 2 connected to the gas supply tube 14 of the handle 1 may be a horn-shaped, conventional or polygonal pipe.

34In FIG. 6 and 7 show a sectional view of an alternative sample of a spray gun with a rotating nozzle in accordance with the present utility model, and an enlarged view of the assembly B of FIG. 6. This alternative sample is suitable for erupting a swirling stream of water aerosol. According to this alternative example, the gas supply pipe 14 of the handle 1 is a T-shaped three-way pipe containing a lower connecting pipe 142 located vertically from its lower side and communicating with the gas supply channel 140 for connecting the water tank 1421. Further, the immersion tube 1422 is connected to the lower connecting tube 142 and hangs in the water tank 1421 near the lower wall of the water tank 1421. Further, the water supply pipe 1423 is mounted in the gas supply channel 140 of the gas supply pipe 14 and extends from the lower connecting pipe 142 through the gas supply channel 310 of the gas supply pipe 31 of the rotary jet former 3 into the gas storage chamber 340 of the rotary nozzle 34 and ends with a water outlet 1424 inserted into the through hole 343. located in the rotating nozzle 34, and passing through the front surface 344 of the rotating nozzle 34. The diameter of the through hole 343 is larger than the outer diameter of the water outlet end 1424 of the water supply tube 1423. When using, connect the air intake tube 11 of the handle 1 to an external source of high air pressure (to the air compressor) using the high pressure discharge hose 111, and then act on the trigger 13 of the handle 1 to control the flow of compressed air from an external source of high air pressure through the air intake pipe 11 and the air supply channel 121 of the valve seat 12 into the gas supply channel 140 of the gas supply pipe 14, causing the incoming compressed air stream to pass through the docking and connecting portion 141 of the gas supply tube 14 and the gas conduit 310 of the gas conduit 31 of the rotary jet former 3 to the gas storage chamber 340 of the rotary nozzle 34 and then to pass from the gas storage chamber 340 through the nozzle opening 342 into the spray gun outer environment . At the same time, the rotating nozzle 34 and the coupling 33 begin to rotate on the outer ring 322 of the bearing 32 from the pressure of the compressed air flowing through them, and thus a strong stream of air is continuously twisted and ejected from the spray gun. When the incoming compressed air stream passes through the connecting portion 312 of the gas conduit 31 and through the through hole 343 of the rotary nozzle 34, a venturi effect is created in the through hole 343, causing the water present in the water tank 1421 to be sucked through the immersion pipe 1422 and the lower connecting pipe 142 into the water supply pipe 1423 with its subsequent withdrawal from the water supply pipe 1423 through the water outlet end 1424. When the fluid stream is ejected from the water outlet 1424, the compressed air is continuously directed to the gas storage chamber 340 of the rotary nozzle 34 and ejected from the oblique hole 342 and from the annular gap in the through hole 343 around the water outlet 1424, causing the liquid flow discharged from the water outlet 1424 to turn into an aerosol. In this way, when the user actuates the trigger 13 of the handle 1, to allow the flow of compressed air to flow from an external source of high pressure air through the air intake pipe 11 into the gas supply pipe 14 and the gas pipe 31 of the rotational jet former 3 and into the gas storage chamber 340 of the rotary nozzle 34, and then enter from the gas storage chamber 340 through the oblique nozzle opening 342 and the annular gap in the through hole 343 around the water outlet 1424 towards the outside of the spray gun, at the same time, the fluid stream is expelled from the outlet 1424 and converted into an aerosol. When a strong jet of compressed air is ejected from the annular gap in the through hole 343 around the water outlet 1424 to turn the erupted air stream into an aerosol, compressed air is ejected from the oblique nozzle opening 342, making the aerosol smaller.

35As shown above, the threaded portion 3111 of the gas conduit 31 of the rotational jet former 3 is screwed into a screw hole 1412 of the docking portion 141; the bearing 32 is mounted on a connecting cylindrical shank 3121 of the connecting section 312 of the gas conduit 31; the lock nut 321 is screwed onto the tubular threaded rod 3122 of the connecting portion 312 of the gas conduit 31. Further, the diameter of the lock nut 321 is larger than the inner diameter of the axial bore 320 of the bearing 32. Thus, the bearing 32 is fixed in place by the lock nut 321, and is protected from falling off the connecting cylindrical shank 3121. Further, the landing recess 330 of the coupling 33 is rigidly connected to the outer ring 322 of the bearing 32; the internal thread 341 of the rotary nozzle 34 is engaged with the external thread 331 of the coupler 33; a gas conducting tube 31 of the rotational jet former 3 is in a hanging position in the accommodation cavity 20 of the attached tube 2; a rotating nozzle 34 is mounted freely rotating at the end of the gas conducting tube 31 in the hole 201 of the attached tube 2. When compressed air is supplied to the gas conduit 310 of the gas conduit 31, it is accumulated in the gas storage chamber 340 of the rotary nozzle 34 and then pushed out of the oblique opening 342 of the rotary nozzle 34, causing the rotary nozzle 34 to rotate with the coupling 33 and the outer ring 322 of the bearing 32. In this way, when a stream of compressed air is supplied through the gas conduit 310 and pushed out from the oblique nozzle opening 342, the rotating nozzle 34 is rotated in the hole 201 of the attachment tube 2, while the gas conducting tube 31 remains stationary in the accommodation cavity 20 of the attached tube 2, without causing centrifugal force, which could push the gas conduit 31 out of the attachment tube 2; Thus, the structural strength of the attached tube 2 and the rotating shaper 3 of the jet is increased. Further, the water outlet 1424 of the water supply pipe 1423 is inserted into the through hole 343 of the rotary nozzle 34 of the rotational jet former 3, and the immersion tube 1422 is connected to the lower connecting pipe 142 and lowered into the water tank 1421 to suck out the water contained therein. Thus, when the fluid flow is sucked into the immersion pipe 1422 and is guided through the water supply pipe 1423 and the water outlet 1424 towards the outside of the through hole 343 of the rotating nozzle 34, the ejected compressed air flowing out from the oblique hole 342 and the annular gap in the through hole 343 around the water outlet 1424 causes the fluid ejected from the water outlet 1424 to become an aerosol. Further, the lock nut 321 is screwed onto the tubular threaded rod 3122 of the connecting portion 312 of the gas conduit 31 of the rotary jet former 3 to hold the bearing 32 and the coupling 33 in place, preventing the bearing 32 and the coupling 33 from falling off of the connecting portion 312. Further, the internal thread 341 of the rotary nozzle 34 is engaged with the external thread 331 of the coupler 33. When the rotary nozzle 34 and the coupling 33 are driven together with the bearing 32, the rotation direction of the rotary nozzle 34 and the coupling 33 is opposite to the screwing direction between the rotational nozzle 34 and the coupling 33, and thus the centrifugal force generated during rotation the rotating nozzle 34 and the coupling 33 does not cause a disconnection between the rotating nozzle 34 and the coupling 33. Thus, when using the assembly of the rotating nozzle 34, the bearing 32 and the coupling 33 will not be pushed out of the accommodation cavity 20 of the attached tube 2, providing a high level of reliability of the spray gun and reducing the degree of danger during use.

36As described above attachment tube 2 and rotary jet former 3 are connected to the gas supply tube 14 of the handle 1 by screwing the threaded portion 3111 of the connecting end member 311 of the rotational jet former 3 of the jet 31 to the screw hole 1412 of the connecting and connecting threaded rod 1411 of the connecting and connecting portion 141 of the gas supply pipe 14 and then screwing the docking and connecting screw hole 211 of the docking and connecting end element 21 of the attachment tube 2 onto the docking dinitelny threaded rod 1411-connection portion 141 connecting the gas supply tube 14, and then bearing 32, the connecting sleeve 33 and the rotating nozzle 34 are mounted on the connecting portion 312 of the gas conducting tube 31 of the rotational jet former 3. When using the air intake tube 11 of the handle 1 is connected to an external source of high air pressure. When, by acting on the trigger 13, the valve seat 12 is opened, compressed air is directed through the air intake tube 11 of the handle 1 and the gas supply channel 140 of the gas supply pipe 14 to the gas pipe 31 of the rotational jet former 3 and to the gas storage chamber 340 of the rotary nozzle 34. Then, compressed air is pushed out of the oblique hole 342 of the rotating nozzle 34. When a stream of compressed air is pushed out of the oblique hole 342 of the rotating nozzle 34, the centrifugal force produced in this way causes the rotating nozzle 34 to rotate in the hole 201 of the extension tube 2. Further, the water tank 1421 is connected to the lower connecting pipe 142 of the gas supply pipe 14, and the immersion pipe 1422 is connected to the lower connecting pipe 142 and lowered into the water tank 1421. In this way, when a swirling stream of compressed air is ejected from the annular gap in the through hole 343 around the water outlet 1424, the fluid flow is sucked into the immersion pipe 1422 and is directed through the water supply pipe 1423 and the water outlet end 1424 towards the outside of the through hole 343 of the rotating nozzle 34, and liquid pushed out of the outlet end 1424, then turns into an aerosol; simultaneously compressed air is ejected from the oblique hole 342, making the aerosol finer.

37In this way, the utility model is aimed at creating a spray gun with a rotating nozzle, including handle which includes a valve seat, trigger and gas pipe extending from the valve seat and ending with the docking and connecting section, extension tube attached to the docking and connecting section of the gas supply tube, and a rotating shaper, including a gas conduit, connected to the docking and connecting section of the gas supply tube and in a hanging position in the accommodation cavity of the attached tube, bearing, coupling and rotating nozzle, mounted on the connecting portion of the gas conduit. When the handle is acted upon by the handle, the compressed air is directed through the handle air intake tube into the gas conduit of the rotating jet shaper and then is pushed out of the oblique hole of the rotating nozzle, and at the same time a centrifugal force is produced, which makes the rotating nozzle rotate in the outlet of the attached tube, and thus the swirling flow compressed air is ejected from the spray gun. Further, the gas supply pipe can be arranged with the lower connecting pipe for connecting the water tank, the water supply pipe is mounted in the gas supply channel of the gas supply pipe and extends from the lower connecting pipe through the gas supply channel of the gas supply pipe of the rotational jet former into the gas storage chamber of the rotating nozzle and ends with the water supply end through hole in rotating nozzle. Thus, when a swirling stream of compressed air is ejected from the annular gap in the through hole around the water outlet, the liquid flow is sucked into the lower connecting pipe of the gas supply pipe and the water supply pipe and ejected from the water outlet end of the water supply pipe, and the liquid pushed out of the water outlet end is then turned into spray can; at the same time, compressed air is ejected from the oblique opening, making the aerosol finer.

38For purposes of illustration, a detailed description of the utility model options is given, however, various modifications and improvements are possible without violating the essence and scope of the utility model. Therefore, this utility model should not be limited to anything other than the attached claims of the utility model formula.
