Aerosol spraying device

(54) Name: Extraction device for dispensing from an aerosol container

The present invention relates to a device for spraying a substance from a replaceable aerosol container removably attached to a mounting plate, in which device the action of a dispensing valve on the aerosol container is provided by an actuator which is displaceable in two opposite directions in one direction through a spring , which is pre-applied under tension, in the other direction by external influence

For the purpose of this, devices are known in which an operating contact of the valve on the aerosol container is made to operate either by means of a mechanical device or by means of a

7010052-4 electrical means for spraying a certain amount of an air purifying, disinfecting, insecticidal product or the like in the form of an aerosol in a room, e.g. a toilet, when the door to the room is set in motion. However, such devices have the disadvantage that they are relatively expensive and require a specialist for their mounting.

The object of the present invention is to eliminate this disadvantage and the invention is characterized for this purpose in that the actuating means is arranged to act against a transmission means stored for rotating or oscillating movement, which means attached to a support plate, which in turn is mounted on the mounting plate. , with the help of a second screw spring and a leaf spring is normally kept in its resting position, that the transmission means is arranged to actuate the valve in response to the displacement of the actuator in one direction but not to actuate the valve in the displacement of said actuator in the opposite direction, nor when it remains in a resting position in any intermediate position.

other characteristics are stated in the subclaims.

The invention will now be described in more detail with reference to the accompanying drawing, in which an embodiment of the invention is shown.

The device shown in the drawing in side view consists of a mounting plate 1, which is arranged to be screwed onto a door, a door frame or a wall. The plate 1 is rigidly connected to an angular iron 2, the one leg of which is bent horizontally and serves as a support for a set screw 3 with convex shape, similar to a sponge. The screw 3 acts against a support head 4, which is indicated by dashed lines in the drawing, which enables an elevation adjustment by means of a clamp 5 for precisely adjusting the function of an aerosol container 6, and the clamp 5 is likewise rigidly attached to the mounting plate 1.

The container 6 and the clip 5 are covered by a removable cover 7 provided with a spray opening 7a. Both are indicated by dash dotted lines in the drawing. The device is furthermore provided at the opposite side of the container surface with a pushbutton 8, which is under the action of a coil spring 9. The button 8 is attached

7010052-4 at the end of a push rod 11 extending through the mounting plate 1 and a guide sleeve 10, the other end of the rod 11 being formed with a pressure head 12.

By pressing the button Ö, e.g. upon closing a door, the spring 9 is compressed and the rod 11 is displaced to a position 11 'during sliding in the sleeve 10, which is screwed onto the mounting plate 1. At its displacement, the pressure head 12 actuates a transmission means, e.g. a cam 15 which is held in its resting position by a coil spring 14. The cam 15 preferably consists of a plastic which slides easily and does not wear, e.g. polyfluoroethylene. This cam can be pivoted about a support plate 13 which is rigidly connected to the mounting plate 1.

In its pivotal movement, the cam 15 acts against a spring plate 16, which is likewise rigidly connected to the mounting plate 1, and the spring 16 makes the valve 17 on the container 6 operable, which results in the spraying of a certain amount of aerosol.

When the door remains closed and the printhead 12 has taken its position 12 ', as shown against the dash dotted line in the drawing, the cam returns to its rest position by the action of springs 14 and 16, and the same applies to valve 17.

Upon reopening of the door, the coil spring 9 is no longer thrown into the compressive action of the door. At the release of the spring 9, the push rod 11 is moved to its rest position, and the pressure head 12 passes over the cam 15 without effect on the valve 17 in the aerosol container 6, so that the function described can be repeated in a new closing of the door.
