Anti-electric shock type water mixing valve

Abstract

The invention discloses an anti-electric shock type water mixing valve. The anti-electric shock type water mixing valve comprises a valve body and a face cover, wherein a handle switch is arranged right ahead the valve body, a mounting seat is arranged at the rear part of the valve body, water inlet chambers and external thread interfaces are arranged on two sides of the valve body, a water outlet chamber is arranged at the lower part of the valve body, two ends of a plastic cold water tube and a plastic hot water tube are respectively sleeved with movable compression nuts, and the cold water tube and the hot water tube are locked on the external thread interfaces of the water inlet chambers of the valve body by virtue of the compression units on one ends of the plastic cold water tube and the plastic hot water tube; the valve body, the external thread interfaces and the mounting seat are subjected to once injection molding by virtue of engineering plastic so as to form an integral structure, and the handle is plastic; the face cover comprises a first hood sleeve and a second hood part, a handle switch is connected with a regulating rod, the regulating rod of a valve core penetrates through a through hole of the first hood sleeve and is inserted into an inner cavity of the handle switch, and the second hood part is sleeved outside the valve body. The anti-electric shock type water mixing valve has the advantages that the structure is simple and reasonable, the manufacturing cost is low, and an electric shock hazard can be effectively prevented.

Description

technical field [0001] The invention relates to an electric water heater accessory, in particular to an electric shock-proof water mixing valve for the electric water heater. Background technique [0002] Water heaters are a daily necessities that are widely used by urban residents in my country. Therefore, people have developed a series of water heaters, including gas water heaters, solar water heaters, and electric water heaters. Electric water heaters do not need to install smoke exhaust systems, and can be used normally in rainy weather. Therefore , and its penetration rate is the highest. The water mixing valve is an important part of the water heater. It can not only introduce cold water into the electric water heater, but also adjust the temperature of the water outlet, making the water temperature more suitable for people to use. The disadvantage of electric water heaters is that there is a potential safety hazard of electric leakage. Since the existing mixing valves...

AI Technical Summary

Problems solved by technology

Although the automatic water cut-off system can prevent the water outlet of the water heater from being electrified, but because the inner tank is connected to the water outlet pipeline, when the water heater leaks, the inner tank and the water mixing valve connected to the inner tank will be charged, and it will still be charged if accidentally touched. Leakage accidents will occur, there is a great hidden danger

[0003] Moreover, the structure of the existing water mixing valve is relatively complicated, and the valve body is also provided with a cover for connecting the handle, so that the manufacturing cost of the water mixing valve is relatively high, and the appearance is quite cumbersome
