[0003] During the use of the existing foam pump, the extrusion head is prone to jamming when extruding, and it needs to be moved up by hand to bounce up, which affects the use, and when the foam pump is producing foam, the foaming effect Not obvious, sometimes the extruded foam is too much, which is wasteful. When the foam liquid is less, it is easy to squeeze out the foam liquid, and the use effect is not good

Embodiment Construction
[0035]The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.
[0036] refer to Figure 1-3 , a glass bead extrusion foam pump, including a pressing piece 1 and a foam pump body 2, the foam pump body 2 is arranged at the lower end of the pressing piece 1, and the pressing piece 1 includes an extrusion head 11, an extrusion pipe 12, a limit mechanism 13, Foam column 14 and anti-jamming mechanism 15, one end of extruding pipe 12 is connected through extrusion head 11, foam column 14 is fixedly installed on the lower end of ex...

The invention discloses a glass bead extrusion type foam pump. The glass bead extrusion type foam pump comprises a pressing piece and a foam pump body. In the downward pressing process of a foam column, a fixing ring can drive a second spring to conduct shortening work. When the foam column is lifted, the foam column is subjected to the springback effect of a first spring and the springback effectof the second spring, and the situation of jamming during pressing is prevented. The invention further discloses a method for generating foam by the foam pump. A pressing groove is pressed downwards,the foam column, a piston and the first spring move downwards in sequence till a glass bead body abuts against the upper end of a suction pipe, and therefore the air pressure in a pump shell is compressed; the pressing groove is loosened, and the foam column, the piston and the first spring restore to the original positions; due to the fact that the air pressure of the pump shell needs to be balanced, a column core in the first spring moves upwards, and therefore foam liquid in the suction pipe is driven to rise till the whole foam column is filled with the foam liquid; and the operation is repeated many times, the foam can be extruded out through an extrusion pipe, and the foam extrusion work is completed.
Description
technical field [0001] The invention relates to the technical field of foam pumps, in particular to a glass bead extruding foam pump and a method for generating foam from the foam pump. Background technique [0002] A foam pump is a device that mixes gas and liquid to produce foam. Existing foam pumps generally include a power unit and a foam generator. After sucking gas and liquid through the power unit, the gas and liquid are passed into the foam generator, and the gas and liquid are mixed by the foam generator to generate foam. [0003] During the use of the existing foam pump, the extrusion head is prone to jamming when extruding, and it needs to be moved up by hand to bounce up, which affects the use, and when the foam pump is producing foam, the foaming effect It is not obvious, sometimes the extruded foam is too much, which is more wasteful. When the foam liquid is less, it is easy to squeeze out the foam liquid, and the use effect is not good. [0004] In view of t...
