Abstract
The present disclosure is a foam machine which is convenient to use, triggers foam generation and extrusion by a sensor, and effectively avoids cross infection caused by hands making contact with the machine.
Claims20
A foam dispensing apparatus, comprising:
- an air-liquid mixing pump comprising an electric motor coupled to a three-cavity part via an eccentric wheel and a movable connecting rod, a valve part, and an air-liquid mixing chamber for generation of foam,
- a liquid storage bottle connected in communication with the air-liquid mixing pump through a pipe, said pipe having a check valve,
- a foam nozzle connected in communication with the air-liquid mixing pump, and
- a sensor arranged on one side of the foam nozzle connected electrically together with a control circuit board to a power supply device.
