Aerosol spraying device

Ea present invention relates to a device for obtaining the diffusion of aerosol leaving a removable removable tank ₃ 'σ ~ ~' * on an assembly plate, device in which, under the action of the movement of a door or other mobile means, the valve of the aerosol tank is controlled by a moving member , erasing in one direction under the effect of a spring which relaxes in the opposite direction to the previous one.

There are known devices achieving the same purpose by means of which a control contact of the valve of the aerosol tank is operated either by a mechanism subject to failures, or by electrical means, in order to diffuse a certain amount of a deodorant, disinfectant, insecticide or other similar product in the form of an aerosol inside a room, especially in a bathroom, when the door of the room is moved. However, such devices have the disadvantage of being relatively expensive and requiring a specialist for their installation and maintenance.

The present invention overcomes these drawbacks by means of a 'control member actuating a transmission member retained in its rest position by springs and capable of pivoting or' oscillating around an axis fixed on a support plate, the latter being rigidly connected to the assembly plate of the device, the control member moving the valve of the aerosol tank in a given direction and having no action on said valve in its movement in the opposite direction or in the intermediate rest positions.

Below is described an embodiment of the object of the invention, given by way of example, and represented in the single figure of the appended drawing.

The device illustrated in the drawing in a side view comprises an assembly plate 1 intended to be screwed on a door, on a door frame or on a wall. The plate 1 is re / 2 / rigidly linked to an angle / of which a horizontally curved wing serves as a support for an adjustment screw 3 having the domed shape of a mushroom. The screw 3 acts on a support head 4, shown in dotted lines in the drawing, said head making it possible to adjust in height using a clamping jaw 5 the exact operating position of an aerosol can. 6, the jaw 5 also being rigidly fixed on the assembly plate 1. .... .

The reservoir 6 and the jaw 5 are covered by a removable sheath 7,. Provided with a diffusion opening 7a, both shown in dotted lines in the drawing. The device is, moreover, provided on the face opposite that for fixing the reservoir hj with a push button 8 urged by a boudir à spring. The button 8 is fixed to the end of a rod ρο us so xjq 11 passing through the assembly plate 1 as well as a guide bush 10, the other //.
