Problems solved by technology

[0003] The disadvantage of this type of device is that the movement of the arm has to be done with relatively high force to ensure activation of the aerosol container
However, slight lateral movement of the output stem of the aerosol container due to the force exerted by the moving arm can damage the aerosol container unless tolerances are very tightly controlled
The rod of the aerosol container may snap off causing the spray device to fail

Embodiment Construction

[0035] The switch unit 10 of the injection device is constituted by a solenoid switch described below. Aerosol containers (see Figure 4 ) 14 of the outlet rod (outlet stem) 12 received in the lower opening 16 of the switch portion 10. The valve stem 12 is sealed by an O-ring 18 and a face seal 20 . The O-ring 18 and the face seal are separated by a gasket 22 . The face seal has an opening 24 through which material from the aerosol canister 14 can pass. The face seal element 20 provides access to a cavity 26 that tapers towards an inlet pin hole 28 . The inlet pin hole 28 is sealed by a primary seal element 30 held in sealing engagement with the inlet pin hole 28 by a movable magnetic armature 32 .

[0036] A plastic bobbin 34 provides a frame upon which many of the elements described below are disposed. Plastic bobbin 34 forms cavity 26 and entry pin hole 28 . The inlet pin hole 28 extends through a raised platform portion 36, which will be described below.

Abstract

A spraying device for spraying fragrance, pest control composition and / or a sanitising composition held within a pressurised container, the spraying device comprising a container receiving section (13) and a switching section (10) wherein the switching section (10) incorporates a solenoid switch.

Description

technical field [0001] The present invention relates to a spraying device, in particular, but not limited to, a switching device for a spraying device. Background technique [0002] Existing spray devices typically consist of an aerosol container held in place beneath a movable arm. The movable arm may be controlled by a timer and motor whereby, at set time intervals, the arm moves and depresses the outlet valve of the aerosol container to eject a spray of material from the aerosol container. [0003] A disadvantage of this type of device is that the movement of the arm has to be carried out with relatively high force in order to ensure activation of the aerosol container. However, slight lateral movement of the output rod of the aerosol container due to the force exerted by the moving arm can damage the aerosol container unless the tolerances are very tightly controlled. The rod of the aerosol container may snap off causing the spray device to fail. Contents of the inve...
