Problems solved by technology

[0002] With the improvement of living standards, people are more and more recognized for foam-type bathroom products, and a batch of foam-type and non-foam-type automatic soap-dispensing products have also emerged on the market. However, most of the existing products of this type use What is more important is the gas-liquid dual-channel dual-output pump or the use of the bubble pump alone, which cannot realize the conversion of the output foam and pure liquid with only one output pump. The operation is cumbersome and inconvenient, and the product structure is complicated, which is not convenient for production.

Abstract

A flow channel control device comprises a flow channel body and a flow channel switching assembly, the flow channel body comprises a fluid flow channel, and a liquid inlet of the fluid flow channel iscommunicated with a fluid outlet. The liquid outlet of the fluid flow channel is communicated with the outside and a mixed flow channel, the liquid inlet is connected with a liquid supply device through the mixed flow channel, a gas-liquid inlet is communicated with the outside through the mixed flow channel, and the liquid inlet and the gas-liquid inlet can be communicated with each other through the mixed flow channel. A flow channel switching assembly comprises a first flow channel controller and a second flow channel controller which are independently arranged, the first flow channel controller is provided with a first sliding insertion part, and the second flow channel controller is provided with a second sliding insertion part. The first sliding insertion part is provided with a first sealing structure, and the second sliding insertion part is provided with a second sealing structure. The first sliding insertion part and the second sliding insertion part are slidably inserted into the mixed flow channel, and the diameter of the first sliding insertion part is smaller than the inner diameter of a pipeline of the mixed flow channel. The flow channel control device is simple instructure, and is convenient to operate and easy to produce.

Description

technical field [0001] The invention relates to the field of household bathroom products, in particular to a flow channel control device applied to gas-liquid two-phase pumps. Background technique [0002] With the improvement of living standards, people are more and more recognized for foam-type bathroom products, and a batch of foam-type and non-foam-type automatic soap-dispensing products have also emerged on the market. However, most of the existing products of this type use What is more important is that the gas-liquid dual-channel dual-output pump or the bubble pump alone cannot realize the conversion of output foam and pure liquid with only one output pump. The operation is cumbersome and inconvenient, and the product structure is complicated, which is not convenient for production. Contents of the invention [0003] The purpose of the present invention is to overcome the deficiencies of the prior art and provide a control device for controlling the two-phase pump t...
