The conventional electric heating faucet has the following working mode that cold water is introduced when a handle rotates to one side, hot water is introduced when the handle rotates to the other side, and the water handle is not heated when the water handle is positioned in the middle. In the electric heating faucet adopting the working mode, when the electric heating faucet is turned off after hot water is used up, high-temperature water still remains in the heating inner container 310, and the remaining high-temperature water can be released and scald users when the electric heating faucet is used next time, and the remaining high-temperature water can cause the aging of the machine to be aggravated and the overheating protector to be started too early.

To solve the above problem, as shown in fig. 7, when the valve core assembly 800 is at different rotation positions, the operation states of the electric heating faucet are as follows:

when the rotation angle of the valve core assembly 800 is from 0 ° to a, the opening between the lower water inlet channel 421 and the upper water inlet channel 431 is closed;

when the rotation angle of the valve core assembly 800 is from a to B, the opening between the lower water inlet channel 421 and the upper water inlet channel 431 is linearly increased, the convex column 510 gradually protrudes rightward under the action of water pressure, and the spinning part 810 is not in contact with the micro switch assembly 700;

when the rotation angle of the valve core assembly 800 is B to C, the opening between the lower water inlet channel 421 and the upper water inlet channel 431 is maintained unchanged, the spinning inclined plane 811 of the spinning portion 810 supports against the micro switch assembly 700 to gradually slide leftward, and the convex column 510 presses the movable contact 710 leftward to a predetermined position to electrically conduct the heating assembly 300;

when the rotation angle of the valve core assembly 800 is from C to D, the opening between the lower water inlet channel 421 and the upper water inlet channel 431 is linearly decreased, the convex pillar 510 keeps the contact position with the movable contact 710 to maintain the electrical conduction of the heating assembly 300, and when the rotation angle of the valve core assembly 800 is the maximum value D, the opening between the lower water inlet channel 421 and the upper water inlet channel 431 is opened.

Taking fig. 7 as an example, when the rotation angle of the valve core assembly 800 is 0 ° to 10 °, no water flows out of the water outlet faucet 200.

When the rotation angle of the valve core assembly 800 is 10 ° to 50 °, the rotation portion 810 is not yet in contact with the micro switch assembly 700, and the heating assembly 300 does not work, that is, the water flowing out of the water outlet faucet 200 at this stage is cold water, and the flow rate gradually increases.

When the rotation angle of the valve core assembly 800 is 50 ° to 70 °, the water outlet flow of the water outlet faucet 200 at this stage is kept maximum, and the rotation portion 810 gradually pushes against the micro switch assembly 700 to slide leftward, and reaches a certain angle, for example, 60 °, the movable contact 710 of the micro switch assembly 700 is pressed by the convex pillar 510 all the time to electrically conduct the heating assembly 300, that is, 50 ° to 60 °, the water outlet faucet 200 flows cold water at the maximum flow, and 60 ° to 70 °, and the water outlet faucet 200 flows hot water at the maximum flow.

In practical application, because of being influenced by water pressure, the protruding height of the protruding column 510 changes, so that the angle of the valve core assembly 800 triggering the switch contact also changes relatively, and the range of hot water flowing out from the water faucet 200 can also be adjusted adaptively.

When the rotation angle of the valve core assembly 800 is 70 ° to 110 °, the movable contact 710 of the micro switch is always pressed by the convex column 510, that is, the water level hot water flowing out of the water tap 200 at this stage is gradually smaller in flow rate. It should be noted that the maximum rotation angle of the valve core assembly 800 is 110 °, and at 110 °, water can still pass through the valve core assembly 800, so that the outlet faucet 200 can flow out the minimum flow of hot water.

This electric heating faucet's working method for always will pass through the cold water district when the user used up hot water and closed tap, some cold water of tap can spout can take away some residual temperatures of some heating members inside like this when passing through the cold water district, and then solve the remaining problem of high temperature water.

The power of the existing electric heating faucet is constant, a user determines the required water temperature by adjusting the water flow, and when the water inlet temperature of the home of the user is too high, for example, in summer or when the water inlet pressure is too low, the water outlet flow is small, the water outlet temperature is high, and scalding is easily caused.

Can adjust the heating power who heats inner bag 310 through setting up controllable silicon 320, prevent that the user from scalding when the too high automatic reduction heating body power of leaving water temperature, and the user can set for leaving water temperature as required, and user experience is better. Meanwhile, the thyristor 320 is arranged on the lower end face of the heating inner container 310, so that heat dissipation is facilitated by the lower temperature end of the heating inner container 310, and the thyristor 320 works more reliably.

The water channel 210 is horizontally arranged in the water outlet faucet 200, the water channel 210 is communicated with the heating inner container 310, and the control assembly 900 is arranged above the water channel 210, so that the internal space of the water outlet faucet 200 is fully facilitated, the whole structure is more compact, the water inlet short circuit of the control assembly 900 is effectively prevented, and the control assembly 900 is more reliable to use.
