Embodiment Construction
[0027] In order to enable those skilled in the art to better understand the technical solutions of the present invention, the present invention will be described in detail below in conjunction with the accompanying drawings and specific embodiments.
[0028] like figure 1 and figure 2 As shown, the embodiment of the present invention provides an electric water faucet with leakage protection function. The electric water faucet with leakage protection function has a metal shell 1, a heating chamber 3 formed inside the water inlet shell 1, and a water inlet channel. , water outlet channel, switch valve, electric switch 15, first pressure comparison chamber 10, second pressure comparison chamber 11, seesaw 13 and elastic diaphragm 9. Specifically, the heating chamber 3 is provided with an electric heating body 4; the water inlet channel communicates with the heating chamber 3 to supply water to the heating chamber 3; the water outlet channel communicates with the heating chamber...

The invention discloses an electric hot water faucet with the function of leakage protection, which has: a heating chamber; a water inlet channel; a water outlet channel; a switch valve; an electric switch; The opposite chamber communicates with the heating chamber; the seesaw is rotatably arranged, and the first end of the seesaw is against the ejector rod; the elastic diaphragm and the leakage protection component. According to the present invention, the difference between the pressure of the water in the water inlet channel and the pressure of the water in the heating chamber is associated with the power on and off of the electric switch, so that when the water flow in the water inlet channel is large, the electric heating body is turned on in advance to heat When the water flow in the water inlet channel is small, the electric heating body is turned off in advance to prevent the electric heating body from being dry-boiled when there is less water in the heating chamber, thereby effectively improving the electric heating body and the electric faucet with leakage protection function. lifespan. The leakage protection component is used to ground the metal casing, thereby improving the safety of the electric water faucet.
Description
technical field [0001] The invention relates to an electric water faucet with leakage protection function. Background technique [0002] The electric faucets with leakage protection function in the prior art all have a heating chamber, and an electric heating body controlled by an electric switch is arranged in the heating chamber. When the electric faucet with leakage protection function is turned on, the electric switch is always in the closed state. The electric heating body is always in the energized state. However, when the water flowing into the heating chamber of the electric faucet with leakage protection function is too little, the electric heating body will burn dry due to the lack of water, thereby shortening the service life of the electric faucet with leakage protection function. Contents of the invention [0003] In view of the above-mentioned technical problems in the prior art, an embodiment of the present invention provides an electric water faucet with a...
