A powered atomizer that repeatedly actuates a conventional manual pump-type atomizer. The powered atomizer is a motor driven unit contained within a housing which holds the atomizer spray head and pump stationary, and provides a mechanism to reciprocate the atomizer container relative to the stationary spray head and pump to actuate the atomizer. The housing is comprised of two separable sections that permits disassembly of the housing and replacement of spent containers. The atomizer container is reciprocated in the housing by means of an electric motor with a motor shaft. The rotary motion of the motor shaft is transformed into reciprocating vertical translatory motion by a cam and follower mechanism. An on-off switch controls the supply of power to the motor, and the container returns to its lowermost position when the motor is stopped, so that it can be manually operated. Power to the motor can be supplied either by batteries within the housing or by a transformer within the housing that is connected to an external electrical source.
