Toilet water flushing part for removing excrement smell

Abstract

This invention discloses a toilet water flushing part for removing excrement smell, comprising a hydraulic water inlet valve, a water discharging base, a hydraulic water discharging valve main body, a hydraulic switch, a water-seal and air-separation overflow passage which is connected on the hydraulic water discharging valve main body in a rotary manner; the top part of the water-seal and air-separation overflow passage is connected with an air extractor; and the part from the air inlet hole of the hydraulic water discharging valve main body to the air inlet hole of the air extractor forms a hollow air extraction pathway. The toilet water flushing part for removing excrement smell provided by the invention is characterized by the functions of removing excrement smell efficiently and quickly, high compatibility, strong environmental adaptation, small volume, low working nose, good water flushing efficiency, long service life, simple manufacturing technology, easy installation and application, low cost, etc.

Description

technical field [0001] The invention relates to the field of sanitary ware, in particular to a toilet water fitting for eliminating fecal odor. Background technique [0002] Existing Chinese patents ZL00263940.8, ZL92245259, ZL200520016073.6, ZL200720131343.7, ZL200520000309.7, etc. all provide a deodorizing device for eliminating the feces odor produced in the process of people going to the toilet, but the mechanism of this device is complicated , The volume is huge, and some technologies need to customize a special toilet ceramic structure to achieve the purpose, and even transform the toilet wall structure. The project is large and the cost performance is low. It is extremely difficult to popularize and promote in real life. Patent No. 200820103039.6 proposes a water tank accessory with deodorizing function that can be used with ordinary toilets. It is composed of a functional box, a drainage part, an induction box, a drainage part, an overflow pipe and a water inlet part...

AI Technical Summary

Problems solved by technology

This kind of water tank accessory has deodorizing function, and can be matched with the toilet of large-size water tank, and it is convenient to install and transform, but this technology also has several major defects at the same time: The pipe and the overflow buoy are set up to improve the pumping effect, which makes the volume of the water tank accessories huge, the compatibility is low, and the manufacturing cost and packaging and transportation cost are increased; (2) the overflow pipe is sealed with an overflow buoy The effect is not good, and the gap between the overflow buoy and the overflow pipe will greatly affect the pumping effect. In order to achieve a sufficient pumping effect, the motor power and speed must be increased, resulting in motor noise and electricity costs; (3) Due to the action of the connector at the moment of drainage, a large amount of water is poured into the hollow drain valve and overflow pipe, which affects the drainage flow to a certain extent

In addition, if the motor is in working condition when flushing, the instantaneous suction negative pressure is likely to suck up the water, thus affecting the life of the motor
