Anti-dry-burning electric heating faucet valve element and faucet made of same

Abstract

The invention discloses an anti-dry-burning electric heating faucet valve element and a faucet made of the same and relates to electric heating faucets and components thereof. An upper ceramic wafer of the valve element is matched with a rotor in a buckled manner; a lower ceramic wafer is fixedly buckled to a flat foot base, and the flat foot base is fixedly buckled to an outer shell; and a cold water flow control groove, a pressure input groove, a pressure relief groove and a hot water flow control groove which are formed in the upper ceramic wafer are matched with a water inlet slotted hole,a water tank communicating slotted hole and an adhesive film cavity slotted hole which are formed in the lower ceramic wafer in a rotary manner, so that cold water and hot water are controlled. The anti-dry-burning electric heating faucet valve element is applicable to all the current electric heating faucets which are under water pressure control. A switching valve is connected with the rotor ina rotary manner and can only be switched on in one direction. The faucet outputs the cold water in the first place and then slowly conducts heating to output the hot water, and the scald risk is avoided; and therefore, when heating is conducted through electric heating tubes, the water tank is filled with water all the time, and the dry-burning phenomenon is avoided. The pressure relief groove isadopted to effectively cut off a switch in the adhesive film cavity slotted hole, and in other words, work of the electric heating tubes is cut off; and furthermore, the dry-burning phenomenon is stopped.

Description

technical field [0001] The invention relates to an electric water faucet and parts thereof, in particular to a valve core of an anti-dry electric water faucet and a water faucet made of the valve core. Background technique [0002] Generally, electric faucets are based on the closed state of the on-off valve, turning out cold water on one side, and hot water on the other side. In the case of hot water, when the switch valve is opened, because the water tank will not be filled with water at once, and the tap water contains a lot of gas, it will cause dry burning and damage the electric heating tube; When the water switch valve is closed, the water flow stops, and the electric heating tube will continue to heat the water in the water tank of the faucet. Since the water tank of the electric water faucet is basically made of plastic material, the aging of the plastic water tank will accelerate over time, reducing the service life of the faucet; Water enters, but the water tank ...

AI Technical Summary

Problems solved by technology

In the case of hot water, when the switch valve is opened, because the water tank will not be filled with water at once, and the tap water contains a lot of gas, it will cause dry burning and damage the electric heating tube; When the water level switch valve is closed, the water flow stops, and the electric heating tube will continue to heat the water in the water tank of the faucet. Since the water tank of the electric water faucet is basically made of plastic material, the aging of the plastic water tank will be accelerated over time, reducing the service life of the faucet; Water enters, but the water tank is still heated, which will cause the risk of the next person using hot water, that is, high-temperature water suddenly comes out of the water tank and scalds people
