Bathroom drainage device

Abstract

The invention discloses a bathroom drainage device, and belongs to the technical field of drainage devices. The bathroom drainage device comprises a drainage pipe, one end of the drainage pipe is connected with a toilet bowl in a matched manner, the other end of the drainage pipe is connected with a gravity pipeline of a drainage system, a jet nozzle is arranged on the wall of the drainage pipe and connected with a solenoid valve in a matched manner, a fish-type clamping film is arranged in a cavity of the drainage pipe, one edge of a fish-type clamping film pipeline is long, the other edge ofthe fish-type clamping film pipeline is short, an upper diaphragm and a lower diaphragm in the fish-type clamping film is hermetically fitted when external air pressure is applied on the fish-type clamping film pipeline, one end of the long pipeline of the fish-type clamping film is communicated with the toilet bowl, one end of the short pipeline of the fish-type clamping film is communicated with the gravity pipeline of the drainage system, the fish-type clamping film and the wall of the drainage pipe form a fish-type clamping film sealed external cavity, and the fish-type clamping film sealed external cavity is connected with the solenoid valve in a matched manner. According to the bathroom drainage device, sewage can be thoroughly drained by a small pipeline, occupied space is small, appearance is attractive, flux is high, switching is convenient, sealing performance is good, drainage distance is 10-50 meters, and the bathroom drainage device is applicable to remote drainage of a bathroom.

Description

technical field [0001] The invention belongs to the technical field of sewage discharge devices, in particular to a toilet sewage discharge device. Background technique [0002] In existing residential quarters, the drainage of the bathroom is directly discharged to the gravity pipe. If it is necessary to renovate a bathroom at a place far away from the gravity pipe, the sewage from the drain pipe to the gravity pipe is generally realized by a pump, but the pump body is relatively large. The noise is high, the small pump body has poor passability and is easy to block, and the large pump body has high cost. Contents of the invention [0003] In view of the above-mentioned problems existing in the prior art, the purpose of the present invention is to design and provide a technical solution for a toilet sewage discharge device, which can ensure thorough sewage discharge, use small pipes to discharge sewage, occupy a small space, have a beautiful appearance, and have a large f...
