Abstract

The invention discloses a foam pump with a breathing sheet. The foam pump with the breathing sheet consists of a nozzle pressing head, a coil cover and a pump body, wherein the pump body comprises a pump body shell, a liquid inlet one-way valve, a large piston, a main valve rod, a valve needle, a rod bottom piston, a spring and a fixed clamping ring. The foam pump uniquely designs a breathing sheet structure, the breathing sheet, the main valve rod and the large piston are matched, so that air inlet is smoother, the pressure of an air inlet cavity is larger, larger internal pressure can be generated, gas liquid is mixed uniformly, and foam is rich.

Description

technical field [0001] The invention relates to a pump, in particular to a foam pump with a breathing sheet. Background technique [0002] Foam pumps are also called foam pumps. They are often used in the packaging of hand sanitizers, detergents, mousse, hairspray and other containers. There is a liquid pump connected to the bottle mouth. There is an air intake chamber near the liquid pump, and the high-pressure liquid and compression After the air is mixed, it passes through the dense foam net to generate a large amount of foam, which flows out from the nozzle of the pressing head. [0003] For example, Patent No. CN201110128683.5 "A spring-mounted foam pump", which is set in the screw gland of the liquid container. When the spring-mounted foam pump is actually used, the liquid container is filled with liquid, and the user presses the The spring external foam pump is used to quantitatively pump out the liquid in the liquid container. During the process of pumping out the l...
