Quickly-dredged deodorizing drain pipe

Abstract

The invention relates to the field of water pipes, in particular to a quickly-dredged deodorizing drain pipe. The pipe comprises an upper pipe section, a U-shaped pipe section and a lower pipe section, the two ends of the U-shaped pipe section are in communication with the lower end of the upper pipe section and the upper end of the lower pipe section respectively, the pipe further comprises a communicating section, the communicating section is a straight pipe, and the two ends of the communicating section are in communication with the lower end of the upper pipe section and the upper end of the lower pipe section respectively; a water overflowing opening is formed in the communicating position between the U-shaped pipe section and the lower pipe section, a sleeve is slidably arranged in the upper pipe section in the length direction of the upper pipe section, a water passing opening is formed in the side wall of the sleeve, and the sleeve can be switched between the two states that the sleeve shields the end of the communicating section and the sleeve shields the end, in communication with the communicating section, of the water passing opening through sliding; and the sleeve is connected with a sliding rod, and the sliding rod extends out of the upper end of the upper pipe section. The drain pipe can be switched to a mode with high drainage efficiency while having a deodorization effect; by arranging a spring, the sleeve can be automatically reset, and the deodorization effect is recovered; and by arranging a cover plate, water in the U-shaped pipe section can be subjected to deodorization.

Description

technical field [0001] The present application relates to the field of water pipes, in particular to a quick-drag anti-odor drain pipe. Background technique [0002] Drainage pipes are mainly responsible for drainage, and can be used in bathrooms and kitchen sinks in buildings. [0003] The Chinese utility model patent with the authorized announcement number CN207863106U discloses an anti-blocking and deodorizing structure of the same-layer decoration drainage pipe, which includes branch line drainage pipes connected to each drain, and main line drainage pipes connected to each branch line drainage pipe. The main line drainage pipe is close to the outlet. There is a "V"-shaped bend at the nozzle, and the "V"-shaped bend includes the first 45° bend, the 90° bend and the second 45° bend that are connected in sequence, and the first 45° bend bends downward. The first 45° elbow bends upwards. The "V" curved portion of the drainpipe forms a water seal to prevent odor from retur...

Problems solved by technology

[0004] In view of the above-mentioned related technologies, the inventor believes that although the V-shaped or U-shaped elbow section can play a deodorizing effect, it causes a large resistance to drainage, resulting in low drainage efficiency
