Abstract
A soap feeding device mounted in a housing comprises an upper housing having a soap reservoir and a lower housing having a control assembly consisting of a power source, a sensor means including a circuit board, a transmission means including a drive means, a reduction gear set, and a crankshaft, and a feeding means. A setting switch on circuit board is extended through hole in the bottom of lower housing being enclosed by a waterproof silicone switch such that user may press the silicone switch to set the dropping of the device. The power source is activated once the sensor senses the stretching out of ones hand. Then reduction gear set is driven to rotate. The rotation of the gear causes the crankshaft to reciprocally move between a pair of clips. Thus the actuated bellow-like extruder compresses air into a barrel which is in cooperation with valve and poppet to extrude soap.
