Water-saving and odor-removing urinal

Abstract

A water-saving and odor-removing urinal comprises a urinal body with a flushing cavity, a water supply tube of the flushing cavity, a water returning elbow at a drain outlet of the lower end of the urinal body, a water line solenoid valve, a proximity type infrared sensor and a control circuit. The water-saving and odor-removing urinal is characterized in that an air suction cavity is formed in anopening of the urinal body, and an odor suction mechanism consists of the air suction cavity, an air guiding tube, a fan, an air line solenoid valve and a control circuit; a turbidity detector is added at the position of a water sealing layer of the water returning elbow, and an intelligent flushing mechanism consists of the water line solenoid valve, the proximity type infrared sensor, the turbidity detector and the control circuit. The water-saving and odor-removing urinal has the positive effects that by the turbidity detector of the urinal, real use conditions of the urinal are recognized, the urinal is flushed according to real conditions, and water consumption of a public washroom is reduced. Diffusion probability of urine excreted by human bodies in an inner tank of the urinal andodor of the urine is reduced. By proximity sensing and turbidity detection, odor can be discharged in time by intelligent control of the urinal, a polluted source is cleared away, and the environmental index of a toilet is protected effectively.

Description

technical field [0001] The invention belongs to the field of fixed buildings, and in particular relates to a water-saving cleaning and deodorizing device for urinals in public toilets. Background technique [0002] For the urinals in the existing public toilets, the main way to clean the urinals is to use proximity infrared sensors to control the delayed flushing of the urinals after use. One is that the false activation of the occlusion generated by the proximity infrared sensor of the human body will lead to waste of water; the other is that the standard flushing water method will also cause waste of water resources caused by too large or too small water volume; the third is the flushing method after defecation Unable to control the stench from the urinal during use. Contents of the invention [0003] The object of the present invention is to provide a water-saving and odor-removing urinal, which overcomes the above-mentioned disadvantages of the existing urinals that o...

AI Technical Summary

Problems solved by technology

[0002] In the existing urinals in public toilets, using a proximity infrared sensor to control the delayed flushing of the urinal after use is the main way to clean the urinal, but because the sensing target does not directly act on human excrement, it is impossible to use water objectively.

One is that the false activation of the occlusion generated by the proximity infrared sensor of the human body will lead to waste of water; the other is that the standard flushing water method will also cause waste of water resources caused by too large or too small water volume; the third is the flushing method after defecation Unable to control urinal odor during use
