Closestool and blowdown device thereof

Abstract

The invention provides a closestool and a blowdown device thereof. The blowdown device comprises a pipeline assembly and a switching assembly, the pipeline assembly comprises a water seal pipeline and a blowdown pipeline, the blowdown device has a blowdown state and a water seal state, and in the blowdown state, the blowdown pipeline is arranged to be used for blowdown of the closestool; in the water sealing state, the water sealing pipeline is arranged to perform water sealing on the closestool; the switching assembly is arranged to be capable of controlling the pollution discharge device to be switched between the pollution discharge state and the water seal state. According to the sewage discharging device, the water sealing function is achieved through the water sealing pipeline, the sewage discharging function is achieved through the sewage discharging pipeline, switching between the sewage discharging state and the water sealing state is achieved through the switching assembly, the sewage discharging function is achieved without siphon, noise generated when a closestool is flushed is reduced, and sewage is completely discharged; the pipeline assembly of the blowdown device and the closestool body can be formed in a split mode, and the forming process difficulty and the machining cost of the closestool body are reduced.

Description

technical field [0001] This article relates to but not limited to the field of toilets, and particularly relates to but not limited to a sewage discharge device of a toilet and a toilet including the sewage discharge device. Background technique [0002] The existing toilet without water tank or with water tank basically cleans the ceramic bowl surface of the toilet through the water outlet of the brush ring, sprays water through the jet port to remove the excrement in the toilet, and uses the S-bent pipeline of the ceramic itself to generate a siphon function to realize Sewage function. [0003] But there are following problems in existing toilet flushing system: [0004] 1. Sewage discharge mainly uses the large water jet at the jet port to spray the excrement into the S-bend pipeline, which is noisy; [0005] 2. The S-bend pipeline needs to be integrally formed with the ceramic toilet body, the process is complicated and the cost is high; [0006] 3. Although the S-ben...

Problems solved by technology

[0004] 1. Sewage discharge mainly uses the large water jet at the jet port to spray the excrement into the S-bend pipeline, which is noisy;

[0005] 2. The S-bend pipeline needs to be integrally formed with the ceramic toilet body, the process is complicated and the cost is high;

[0006] 3. Although the S-bend pipeline can produce a siphon effect and can discharge sewage more effectively, it still has the problem of insufficient sewage discharge capacity. When the excrement is large and large, it cannot be discharged cleanly.
