SOAP DISPENSING APPARATUS FOR COUNTER-MOUNTED AUTOMATIC SOAP DISPENSOR
First Claim
1. A soap dispensing apparatus, for use in soap dispensing by an automatic countertop soap dispenser, comprising:
- a drive device, including a motor and a reduction gear set driven thereby;
a rear board, joining a frame that holds the motor in the drive device, having a recessed area, a main shaft groove is provided on the bottom thereof;
a first packer, having the same profile as that of the main shaft groove of the rear board, and tightly disposed therein;
an inlaid board, having the same profile as that of the recessed area of the rear board, and disposed therein, said inlaid board having two shaft bores and, on one side, a circumferential groove;
a second packer, having the same profile as that of the circumferential groove of said inlaid board, and disposed therein slightly protruding therefrom;
an end cover, having a chamber extending upward to form an outlet passage and downward to form an inlet passage;
a circumferential groove having the same profile as that of said second packer provided to the peripheral of said chamber, and used to contain said second packer slightly protruding from said circumferential groove of said inlaid board, enabling hermetic seal between the end cover and one side of the rear board; and
a pair of soap displacing gears, disposed in the chamber of said end cover, consisting of a drive gear and an idler gear in mesh side by side, wherein the drive gear is coupled to the output shaft of the gear set of said drive device.

Abstract
A soap dispensing apparatus for an automatic countertop soap dispenser, comprising a motor and a reduction gear set driven thereby, said reduction gear set with an output shaft coupled to the drive gear of a pair of soap displacing gears in mesh side by side, said soap displacing gears disposed, by precision fit, in a chamber that extends upward and downward to form an outlet passage and an inlet passage, wherein the outlet passage is connected to a countertop soap dispensing spout, and the inlet passage to a soap containing reservoir. Whereby an upward suction force induced by the rotation in mesh of the drive gear and the idler gear of said soap displacing gears is used to suck the liquid soap through the inlet passage and out of the outlet passage, thus to lift the liquid soap above countertop to achieve soap dispensing.
