Description

A kind of novel extrusion type foam pump

Technical field

The utility model relates to a kind of extruding container foam makers, and in particular to a kind of novel extrusion type foam pump.

Background technique

Foam pump is the packaging of common daily use chemicals cleaning supplies, and foam pump will be contained by internal structure design by pressure There are the liquids and gases of foaming agent to be mixed to form foam, and foam outflow is uniformly refined by strainer, use is provided.

The general basic structure of foam pump is with liquid needed for providing the air cavity and mix-froth of gas needed for mix-froth The sap cavity of body, and gas and liquid needed for being provided with the pressure source and mix-froth of gas and liquid needed for mix-froth Channel.The patent of various foam pumps is exactly to generate the only of respective foam pump by the different designs to these general basic structures Special structure and performance；

Usually used foam pump product is push type foam pump, and when use needs first to press the pump head of foam pump, will be steeped Foam pumps out to hand, then reuses foam on hand.This push type foam pump is usually made of multiple part combinations, pump Main body is large and small two cylinders and large and small two pistons, and big cylinder forms the air cavity of foam pump, and small cylinder forms foam pump Sap cavity, big cylinder provide gas pressure source with big piston for air flue, and small cylinder provides liquid pressure source, piston with small piston The channel of gas and liquid needed for inside has one-way flow channel to form mix-froth, is connected on piston channel by pressure mouth, empty Gas access and liquid material access are pooled to same bubble output hole and are mixed into foam, and uniformly refine foam through filter screen, finally by pressing Mouth outflow uses.

Although above-mentioned push type foam pump structure is simple, inconvenient to use, there are the following problems:

In use, first needing fixer material container, then pressure mouth discharge foam is pressed in pressing, and this operation usually requires two Make manually, a hand fixer material container presses pressure mouth simultaneously, and another hand connects foam, causes inconvenient to use；

In order to ensure by pressure mouth drive piston after pressing can smooth homing, piston by spring force reset, And in order to guarantee the sealing between cylinder and piston, tight fit will form between cylinder and piston, this results in cylinder and piston Between relative motion resistance it is very big, it is therefore desirable to the spring force of return piston is larger, this results in pressing is needed by the power of pressure mouth It wants larger, causes inconvenient to use；

Since use process is first to take bubble, then smear use, it can not accomplish that bubble is taken to carry out simultaneously with smearing, cause using not It is convenient；

Chinese Patent Application No. 201410574155.6 proposes a kind of scheme of the formula foam pump of extruding, but this side Case needs to have the function of to squeeze and resetting the use to assist foam pump, this extruding by the container that foam pump is matched Formula foam pump itself can not independently have the function of conversion foam, and use is very inconvenient.

The Chinese Patent Application No. 201710816100.5 announced also proposed a kind of side of the formula foam maker of extruding Case, this scheme can't be the feasible squash type foam maker scheme of an independence, because providing liquid necessary to lacking foam maker Expect the technical essential of pressure, and this scheme also lack air cavity air be extruded away after the technology of air cavity make-up gas want Point, and the two technical essentials are necessary to realizing a complete foam maker；

This scheme setting pressing main body, and two independent air cavitys and sap cavity are isolated by baffle in pressing main body, And air cavity and sap cavity press moulding provided with independent, cause the pressure of air cavity and sap cavity not coordinate unanimously in this way, cause gas It is difficult into foam in mixing with liquid；

Directly air cavity and sap cavity is arranged in pressing main body in this scheme, and pressing is both provided on air cavity and sap cavity Glue, this result in two kinds may: first is that when liquid fail it is most of full of sap cavity when, will cause and squeeze sap cavity and what is be discharged is liquid Chamber upper air can not go out liquid and form foam；Second is that when liquid is largely full of sap cavity, due to the density contrast of gas and liquid It is different very big, it causes to squeeze the extruding glue on the gentle chamber of sap cavity simultaneously and has that air cavity is soft, the hard effect of sap cavity, using effect is very poor；

Sap cavity is arranged in pressing main body this scheme, and the gas-liquid mixed due to generating foam needs more air, makes It is larger at pressing main body, thus the sap cavity pressed in main body also can be larger, it is more that this will result in the hydraulically full needs of sap cavity Compression number, therefore when using the squash type foam maker of this structure for the first time, it needs repeatedly to press ability exruded foams, causes to make With difficulty.
