Water-gas mixing flushing device, supercharging device and design method

Abstract

The invention discloses a design method of a water-gas mixing flushing device. The water-gas mixing flushing device comprises a first cylinder, water inlet pipelines, a flushing pipeline, a first valve and a second cylinder, wherein the first cylinder is fixedly connected with the second cylinder, the first cylinder comprises a first cavity, a first piston and a piston pull rod, water at the two sides of the first piston can flow, the bottom of the first cavity is communicated with the flushing pipeline, the flushing pipeline is provided with the first valve, the top of the first cavity is communicated with the first water inlet pipeline, the second cylinder comprises a second cavity, a second piston and an exhaust pipeline, the second piston is fixedly connected with the first piston through a first pull rod, the bottom of the second cylinder is communicated with the exhaust pipeline, an upper base of the second piston and a cavity of the second cylinder are not sealed, rising and falling of the second piston cannot be affected by the resistance of positive and negative pressure of the air, and the top of the second cylinder is provided with an exhaust hole.

Description

technical field [0001] The invention relates to the field of sanitary ware. Background technique [0002] In the prior art, for some situations where the tap water pressure is low, the flushing toilet often has the phenomenon that the stool cannot be flushed clean. If a higher pressure gas or liquid is required to improve the flushing effect, it is usually achieved by a compressor or a hydraulic pump. Under certain conditions, it cannot be realized by existing compressors or hydraulic pumps, so it is difficult to obtain higher pressure gases or liquids. [0003] In the prior art, water-gas mixed flushing has a better flushing effect, which is very conducive to water saving and clean flushing. [0004] In the case of low tap water pressure, the flushing of the toilet is very prone to the phenomenon that the stool and urine in the toilet bowl and trap cannot be flushed clean. [0005] At present, the faucet for washing hands, especially in the case of washing things, if the ...

Problems solved by technology

[0004] In some situations where the pressure of tap water is low, the flushing of the toilet is very easy to cause the stool and urine in the toilet bowl and trap to not be flushed clean

[0005] At present, the faucet for washing hands, especially in the case of washing things, if the water flow is too small, the coverage area of ​​the water flow is small, and the effect is very bad. Therefore, the water flow is usually very large, and too much water flowing out is a waste, and the water flow is large. , prone to the disadvantages of splashing water
