Soapdispenser having a squeeze pump
First Claim
1. A soap dispenser comprising:
- a soap container having a flexible dispenser hose with dispenser nozzle coupled thereto;
a housing having a space formed therein for holding said soap container therein with said dispenser hose and nozzle positioned to direct soap from said container through said housing;
a gear box located in said housing and having an outlet shaft therefrom, said output shaft having a crank member attached thereto;
an electric motor located in said housing and coupled to said gear box for driving said output shaft;
pumping means located in said housing for receiving said dispenser hose therethrough for dispensing soap from said container responsive to the comprising of said flexible hose when actuated by said electric motor when said electric motor is actuated, said pump means including a pressure plate located on one side of said dispenser hose and a squeeze member coupled to said gear box output shaft crank arm and riding in a guide plate and located to extend part way around the other side of said dispenser hose for compressing said hose against said pressure plate when said squeezing member is pulled by said electric motor driving said gear box output shaft whereby soap is directed through said dispenser hose from said container through said dispenser nozzle; and

Abstract
A soap dispenser apparatus has a housing having a space formed in the housing for holding a soap container of a predetermined shape. The soap container has its own dispenser hose and nozzle formed therein and the dispenser hose fits through a squeeze pump and becomes part of the pump pumping the soap from the container. An electric motor has a gear box for gearing the motor down located in the housing and positioned to actuate a squeeze member to squeeze the dispenser hose against a pressure plate made of a self lubricating polymer. A sensor, such as an infrared sensor, senses a person'"'"'s hand in line with the output of the soap container and dispenser nozzle and is coupled through a circuit to the electric motor to actuate the squeeze pump to pump the soap onto a person'"'"'s hand positioned to receive the soap.
