Water-saving and odor-removing urinal

Abstract

A water-saving and odor-removing urinal, comprising: a urinal with a flushing chamber, a water supply pipe for the flushing chamber, a reverse water bend at the sewage outlet at the lower end of the urinal, a waterway solenoid valve, a proximity infrared sensor, and a control circuit. The improvement is: an air suction chamber is set along the pool mouth of the urinal, and the odor suction mechanism is composed of the air suction chamber, the air induction pipe, the fan, the air circuit solenoid valve, and the control circuit; a turbidity detection is added at the position of the sealing water layer of the reverse water bend The device is composed of a waterway solenoid valve, a proximity infrared sensor, a turbidity sensor, and a control circuit to form an intelligent flushing mechanism. The positive effect of the present invention is: through the turbidity detector of the urinal, the real use condition in the urinal can be identified, and the flushing can be performed according to the real condition, so as to reduce the water consumption of the public toilet. It reduces the probability of diffusion of human body excreting urine and its peculiar smell in the inner tank of the urinal. Through proximity sensing and turbidity detection, the intelligent control urinal immediately discharges odors, removes pollution sources, and effectively protects the environmental indicators of the bathroom.

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...

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 t...
