An automatic soap dispensing device, particularly a device which can be activated by photoelectric or infrared sensor via a control circuit, i.e., a motor reducing gear set in a drive device driving a drive wheel with a considerable torque at low speed so that an eccentric wheel on the drive wheel can push a squeezer set which in turn squeeze a soap hose to dispense liquid soap accordingly; and a micro switch is touched when the drive wheel is rotated to a certain angle to stop the motor, upon which the squeezer set returns its initial position by the inherent elasticity of the hose without any need to engage any gear with the reducing gear set and possibility of seizure between gears which may adversely affect operation of the soap dispensing device.

[ We claim:] [1.] An automatic soap dispensing device, comprising:a housing;a cap upon which said housing is mounted;a seat mounted within said housing;a liquid container supported by said seat within said housing;a support board mounted within said seat;a motor fixed to said support board;a driving mechanism fixed to said support board and driven by said motor, said driving mechanism including a reducing gear set, a drive wheel, a squeezer set and a microswitch;a spiral eccentric wheel coaxially installed on one side of said drive wheel for rotation therewith, wherein a last gear of said reducing gear set has a coaxially installed pinion which engages said drive wheel for driving said drive wheel when said reducing gear set is driven by said motor; anda cam coaxially installed on the other side of said drive wheel for rotation therewith, said cam having a raised portion thereon, wherein said microswitch is fixed to said support board at a proper position so that said raised portion of said cam contacts said microswitch to stop said motor when said cam rotates into a certain position.
