This invention relates to an electric heating system, which contains aerosol-containing substrate. In particular, this invention relates to an electric heating system for smoking, which contains an aerosol dispensing substrate, and this aerosol-containing substrate is a liquid.

In many well-known documents, for example, IZ-A-5060671, IZ-A-5388594, IZ-A-5505214, IZ-A-5591368, OTO-A-2004/043175, EP-A-0358002 and OTO-A-2007 / 131449, describes electric curing systems that have different advantages. One of these advantages is that they substantially reduce the side jet of smoke while at the same time allowing the smoker to temporarily stop and recover the smoking.

Other known documents such as EP-A-0295122, EP-A-1618803 and EP-A-1736065 describe electrical smoking systems in which the aerosol-containing substrate is a liquid. This liquid can be placed in a cartridge that can be placed in the cabinet. The intended power supply, such as a battery, is connected to a heater intended to warm the liquid substrate during dragging to form an aerosol that comes in the fryer.

Known electrically heated smoking systems, including those described above, really have numerous advantages, but there is still room for improvement. Accordingly, the purpose of this invention is to provide an improved electric heating system.

According to a first aspect of the present invention, an electric heating chamber system is created which includes a hollow buccal portion and a variable part inserted into the mouth, said cavity attachment portion includes an electric power supply and an electric chill; said component inserted into the mouth includes a container for the liquid, a capillary magnet having a first end and a second end, the first end to contact with fluid extends within the fluid container, at least one heating element for heating the second end of the capillary moss, the outlet for air and chamber formation of an aerosol, which is located between the second end of the capillary gonot and the outlet for air; moreover, when the hollow bearing part and the part inserted into the gate are connected, said at least one heating element is in an electrical connection to the power supply through said electric circuits, the electric circuits are made with the possibility of feeding the pulse of the electric current to said at least one heating element when the user initiates the tightening, and the channel is determined for the passage of air from at least one air inlet to said outlet an air hole through the aerosol formation chamber, to which the air flow is directed around the heating element and the other gogo end of capillary wick.

At least one inlet for air can be made in the hollow outboard part or in the part inserted into the mouth. When using electric heating system, the liquid under the action of capillary forces in the capillary pus comes from the reservoir for the liquid of the heating element. When the heating element is activated, the liquid from the second end-capillary bud is evaporated by means of the heating element to form an over-saturated vapor. The formed super-saturated vapor is mixed with the air flow and transferred to it from at least one inlet to the air into the aerosol formation chamber. In the body of aerosol formation, the steam condenses with the formation of an aerosol, which moves toward the outlet for air and into the user's mouth.

The electric heating system of the present invention provides several advantages. Firstly, because the variable part inserted into the mouth includes at least one heating element, a reservoir for fluid and a wick, all elements that are potentially included in the contact with the liquid are replaced when the part inserted into the mouth is replaced. There is no cross-contamination in the hollow incisor between the various parts inserted into the mouth, for example, those for which different fluids are used. In addition, the liquid in the liquid container is protected from oxygen (due to the fact that oxygen in essence can not get into the container for liquid through the capillary oppression), and in certain embodiments, said liquid is protected from light in such a way that the risk of decomposition of the liquid is significantly reduced. Thus, a high level of hygiene can be maintained. Secondly, the design of the part inserted into the mouth provides low probability of leakage from the contents of the liquid, which does not occur in many well-known electric heating chambers. This prevents the flow of liquid, and also makes it difficult for an outsider to access the liquid by removing the part inserted into the mouth. Also, if the part inserted into the mouth is replaced with the appropriate periodicity, then the probability of contamination of the heating element is insignificant. Thirdly, due to the fact that the electric circuits give an impulse to the electriccurrent when the user initiates a delay, as well as because the flow of air is diverted This prevents the flow of liquid, and also makes it difficult for an outsider to access the liquid by removing the part inserted into the mouth. Also, if the part inserted into the mouth is replaced with the appropriate periodicity, then the probability of contamination of the heating element is insignificant. Thirdly, due to the fact that the electric circuits give an impulse to the electriccurrent when the user initiates a delay, as well as because the flow of air is diverted This prevents the flow of liquid, and also makes it difficult for an outsider to access the liquid by removing the part inserted into the mouth. Also, if the part inserted into the mouth is replaced with the appropriate periodicity, then the probability of contamination of the heating element is insignificant.

In this embodiment, the block 105 and the delay detection system 107 are programmable. The block 105 and the delay detection system 107 can be used to control the operation of the device. In this embodiment, when the detecting detection system 107 detects that the user is tightening, the battery supplies a current pulse of a predetermined duration to the heating coil 209. This predetermined pulse duration of the current will depend on the amount of fluid required for one delay and the time required to evaporate this amount of liquid. This, in turn, depends on the properties of the liquid, the heating coil and the capillary wry. This predefined time can range from 0.5 s to 3 s.

In this embodiment, the cartridge 203 in the portion inserted into the mouth has the following dimensions to accommodate a sufficient amount of fluid for a predetermined number of pins. After this predetermined amount of drawbacks, the cartridge may be filled again, but in the preferred embodiment, the part inserted into the mouth is completely replaced. The predetermined amount of delays is ideally ranging from 200 draws to 2,000 draws and will depend on the size of the cartridge, the portion that is put into the mouth, and the entire device, as well as the properties of the applied fluid. The cartridge 203 can be made of any suitable material. Examples include glass and polymeric plastics, such as PET or other, used in the pharmaceutical or food industries. This material should be selected so that,

In the embodiment shown in FIG. 1-3, when the hollow mounting portion and the portion inserted into the mouth are connected, the cartridge 203 is located above the flow relative to the other end of the wick 207b and the heating coil 209. Thus, the ambient air is absorbed through the inlet vents 115 for air and passes around cartridge 203 in front of how to reach the second end of the wick 207b and the heating coil 209. However, in an alternate embodiment, the part inserted into the mouth may have such a construction that when the hollow outboard portion and the part inserted into the mouth, the cartridge is located below the flow relative to the second end of the wick and the heating coil. In this embodiment, the ambient air is drawn through the inlet openings of the air,

Capillary wick can be made of a variety of porous or capillarymaterials, and optionally preferred, has a well-known predeterminedcapacity. Examples include ceramic or graphite materials in the form of fibers or baked powders. Prints of different porosity can be used to match the physical

Properties of various liquids, such as density, viscosity, surface tension and vapor pressure. The nestmust be suitable for feeding the required amount of liquid to the heating coil.

The part inserted into the mouth and the hollow buccal part have the dimensions and shape to provide the possibility of their connection to obtaining an electric heating system that has acceptable dimensions and can be applied by the smoker. The elements of the part that are placed in the mouth and the hollow incisor, including the power supply, electric circuits, fluid reservoirs, the wick, the heating element and the aerosol formation chamber, have the appropriate dimensions and shape for the design of the system. In a preferred embodiment, the system is portable and can have a size similar to the size of the usual cigar or cigarette.

The system of the present invention makes it possible to control the concentration of particles (mg / l or volume) in aerosol, the average particle size in aerosol, and the distribution (range) of particle size in aerosol. This can be controlled by varying one or more of the following factors: the composition of the aerosol formulation in the liquid, the transfer of energy (thermal power per unit area of ​​surface) on the heating element, the design of the camera formation aerosol and operating temperature. The transfer of energy will depend on numerous factors, including the materials used for heating elements and the wicker, the diameter of the wick, the design of the heating element, including - if the heating element is a coil - the length, diameter and step (distance between the turns) of the coil, and as well as the power supplied to the heating element.

The operating temperature should be controlled in such a way as to ensure, if possible, that there is no undesirable deterioration in the quality of the aerosol or aerosol formers. This can be achieved, for example, by controlling the temperature of the heater if the heater is made of an acceptable metal or alloy, by applying a change in electrical conductivity, or by controlling the amount of energy supplied to the heater. The operating temperature of the preferred heating element is in the range of 100 ° C. to 300 ° C. The construction shown in the figures can work in this temperature range and can also provide a short reaction time (the time between the user's tightening from the system and the flow of aerosol into the user's mouth through the outlet for air - this may be called "
