Squatting pan with excrement residue sensing cleaning apparatus

Abstract

The invention relates to a squatting pan with excrement residue sensing cleaning apparatus. The squatting pan comprises a squatting pan body, a water supply pipe connected with an annular flushing cavity of the squatting pan, a water route electromagnetic valve, an approaching-type infrared sensor and a control circuit, and is characterized by being additionally provided with an odor pumping mechanism and an intelligent flushing control mechanism; the odor pumping mechanism comprises a draught pipe, a fan, an air route electromagnetic valve and a control circuit, and the intelligent flushing control mechanism comprises an excrement residue sensor installed in the squatting pan, a turbidity detector installed on a water return elbow water sealing layer on the lower end of a draining openingof the squatting pan and a control circuit connected with the approaching-type infrared sensor, the water route electromagnetic valve, the excrement residue sensor and the turbidity detector. The squatting pan has the beneficial effects that a majority (more than 80 percent) of odor can be pumped from a toilet groove, and the probability of the continuous odor release of the excrement residues inthe toilet can be reduced. The water consumption of the squatting pan is reduced.

Description

technical field

[0001] The invention belongs to the field of fixed buildings, in particular to a squatting pan with deodorizing and water-saving functions in public toilets. Background technique

[0002] Now, squatting toilets are still mostly used in domestic public toilets. Toilets that use squatting toilets usually have a relatively strong odor. Its reason one is that the human body can not form a certain degree of sealing to it when the squatting pan is used, and the bad smell is scattered without hindrance, and more bad smell is distributed in the toilet. In addition, the sensing target of the existing induction automatic flushing squat toilet is the human body instead of human excrement, and it is usually set to flush once when the human body leaves the toilet. Often there is no excretion retention in the urinal, a small amount of excretion retention and excessive flushing, wasting water resources. It also often occurs that the excrement retention is not flushed cle...
