Abstract

The invention discloses a foam pump which comprises a liquid chamber pump unit, an air chamber pump unit, a foam forming device and a driving device, wherein the foam forming device comprises one or a plurality of screen nets arranged on a discharge channel and an air-liquid mixing chamber; the liquid chamber pump unit comprises a liquid chamber and a liquid chamber linking device; the liquid chamber linking device is used for conveying liquid from the liquid chamber to the air-liquid mixing chamber through a liquid conveying channel under the linkage of the driving device; the air chamber pump unit comprises an air chamber and an air chamber linking device; the air chamber linking device is used for conveying air from the air chamber to the air-liquid mixing device under the action of the driving device; the the air chamber pump unit comprises a resetting unit which is directly arranged in the air chamber; the liquid chamber linking device comprises a material discharge valve which is arranged at the interaction part of the liquid conveying channel and the air-liquid mixing chamber. Because the material discharge valve is arranged at the interaction part of the liquid conveying channel and the air-liquid mixing chamber, the liquid can directly enter the air-liquid mixing chamber through the liquid conveying channel, and can not be directly remained in a longer liquid conveying channel, and pollution is not caused.

Description

technical field [0001] The present invention relates to a foam pump and more particularly to a dispensing liquid sprayer comprising the foam pump. Background technique [0002] The existing foam pump is composed of a suction cylinder and a suction liquid cylinder whose outlets are connected. The suction cylinder is composed of a cylinder body and a piston. When in use, press the pressure head to make the piston of the suction cylinder and the piston of the suction liquid cylinder work synchronously. The suction liquid cylinder sucks the emulsion of the container, and the suction cylinder sucks the air, and then the emulsion and air are combined at the outlet. Mixing becomes foam spraying, but this structure is costly. [0003] In addition, Patent No. ZL2005200636954 discloses another type of foam pump, which includes a cylinder body, a press head, a plug tube and a spring. The center and the air cylinder are located on the periphery of the liquid cylinder, the air cylinder...
