Closestool flushing device capable of improving noise

Abstract

The invention discloses a closestool flushing device capable of improving noise, which comprises a flushing valve and a drainage pipeline, one end of the drainage pipeline is communicated with the flushing valve, and the other end of the drainage pipeline is communicated with a closestool urinal; an overflowing channel for water flow to flow and at least one exhaust channel communicated with the outside are arranged in the drainage pipeline, and when the water flow flows to the overflowing channel, part or all of gas in the overflowing channel is exhausted through the exhaust channel. When thedevice is used for flushing, the device can be used for flushing, most of air in the flushing valve and air in the drainage pipeline can be exhausted or stored in the exhaust channel through the exhaust channel, noise generated by the fact that a large amount of air flows to the spraying holes in the bottom of the toilet bowl urinal through the drainage pipeline and is mixed with water to be sprayed out is avoided, and the noise problem of the toilet bowl flushing device during flushing is greatly solved.

Description

technical field [0001] The invention relates to a toilet flushing device with improved noise. Background technique [0002] According to the source of flushing water, toilets can be basically divided into two categories: tank type and tankless type. There are tank-type toilets, most of which flush the toilet by the water stored in the tank, and tankless toilets, most of which are directly communicated with the water pipe, and utilize the water pressure of tap water to flush the toilet. [0003] The urinal of the above-mentioned tankless toilet is all communicated with the flushing valve for controlling the flow of water through the drainage pipe. When the toilet starts to flush, the flush valve opens, and the water mixed with the residual air in the drain pipe quickly flows out of the drain pipe and then sprays out through the spray holes on the toilet bowl, causing the compressed air to expand with water to produce a sonic boom. In particular, when the spray hole is locat...

AI Technical Summary

Problems solved by technology

[0004] In order to solve the above problems, the present invention provides a toilet flushing device with improved noise. When flushing, most of the air in the flushing valve and the air in the drainage pipe can be discharged through the exhaust passage or stored in the exhaust passage. Avoid the noise caused by a large amount of air flowing through the drainage pipe to the spray hole on the toilet bowl and mixed with water, which greatly improves the noise problem
