Compact spray device

Abstract

An automatic discharge device includes a housing retaining two containers therein and an actuator arm attached to the housing and movable between first and second positions. The automatic discharge device also includes a drive unit for automatically moving the actuator arm into one of the first and second positions in response to a signal from at least one of a timer, a sensor, and a manual switch. The movement of the actuator arm actuates a valve stem of one of the two containers in one of the first and second positions and the actuator arm is adapted to spray the contents of the two containers.

I/We claim: 
     
         1 . An automatic discharge device, comprising:
 a housing retaining two containers therein;   an actuator arm attached to the housing and movable between first and second positions; and   a drive unit for automatically moving the actuator arm into one of the first and second positions in response to a signal from at least one of a timer, a sensor, and a manual switch, wherein the movement of the actuator arm actuates a valve stem of one of the two containers in one of the first and second positions, and wherein the actuator arm is adapted to spray the contents of the two containers.   
     
     
         2 . The automatic discharge device of  claim 1 , wherein the two containers are aerosol containers. 
     
     
         3 . The automatic discharge device of  claim 1 , wherein the housing includes surfaces defining a recess for securely holding the two containers. 
     
     
         4 . The automatic discharge device of  claim 3 , wherein the drive unit includes at least one gear disposed substantially between the recess and a rear panel of the housing. 
     
     
         5 . The automatic discharge device of  claim 1 , wherein the drive unit includes a two-way drive motor. 
     
     
         6 . The automatic discharge device of  claim 5 , wherein the actuator arm moves along a path substantially parallel to an axial length of one of the two containers upon activation of the drive motor. 
     
     
         7 . An automatic discharge device, comprising:
 a housing having a recess adapted to retain a container therein;   a combination of sensors for detecting an environmental condition;   an actuator arm attached to the housing and movable between first and second positions; and   a drive unit for automatically moving the actuator arm into one of the first and second positions in response to a signal from at least one of the combination of sensors, a timer, and a manual switch, wherein the movement of the actuator arm actuates a valve stem of the container allowing a fluid disposed in an interior of the container to be dispensed and exited from the housing in an upward direction through an upper end thereof.   
     
     
         8 . The automatic discharge device of  claim 7 , wherein the actuator arm moves along a path substantially parallel to an axial length of the container upon activation of the drive unit. 
     
     
         9 . The automatic discharge device of  claim 7 , wherein the drive unit includes at least one gear disposed between the recess and a rear panel of the housing. 
     
     
         10 . The automatic discharge device of  claim 7 , wherein the combination of sensors are light sensors. 
     
     
         11 . The automatic discharge device of  claim 7 , wherein the combination of sensors are motion sensors. 
     
     
         12 . The automatic discharge device of  claim 7 , wherein the drive unit includes a two-way drive motor.
