ABSTRACT:
A pressurized can (3) containing material to be dispensed by evaporation is inserted into a case (1) and secured therein by latches (16). An actuator assembly comprises an annular solenoid (21,22) surrounding a plunger (28). The plunger (28) has an axial bore for receiving a shaft tube (29) which is pressed by plunger (28) on a can valve when the solenoid (21,22) is energized. The shaft tube (29) is provided with a nozzle tube (31) extending toward the opening (37) of an annular electrical heating device (34) comprising a perforated disk (39). Material from the can (3) is released by energizing the solenoid (21,22) automatically at selectable time intervals for preset durations. The material falls on the heated perforated disk (39) and evaporates through the holes (40) in the disk (39) into the atmosphere. Higher amounts of insecticide, deodorant and disinfectant agents can be automatically evaporated into a space of higher volume with less material by this apparatus.
