PIEZOELECTRIC FOAMING PUMP

摘要

A piezoelectric foaming pump is provided herein. The piezoelectric foaming pump includes a housing having a first opening for receiving a liquid from a liquid container and a piezoelectric element secured to the housing. The piezoelectric element includes a plurality of holes there through. In addition, the housing includes an air inlet. Although the piezoelectric element has holes there through, prior to activating the piezoelectric element, liquid does not pass through the plurality of holes. When the piezoelectric element is energized, liquid passes through the plurality of holes due to the rapid vibration of the piezoelectric element and is dispensed as a foam. Additionally, a piezoelectric foaming pump having a fluid pump chamber; an air pump chamber; a mixing chamber; a piezoelectric element; and an outlet nozzle is disclosed herein. During operation, fluid pumped from the fluid chamber mixes with air pumped from an air chamber in the mixing chamber and the resulting mixture is passed through the piezoelectric element and dispensed out of a nozzle.
