Description

Technical Field

[0001] This utility model belongs to the field of electric water heater technology, and more specifically, it relates to a fast-heating constant temperature preheating antifreeze electric water faucet. Background Technology

[0002] A faucet is a common water valve device used to control the opening and closing of water flow and to regulate the water flow rate. It is widely used in many fields such as daily life, industrial production, and commercial establishments.

[0003] While existing faucets can heat water, they require high water pressure to heat it; if the water pressure is too low, the heating effect is not obvious, making them less practical. Existing devices tend to loosen after being installed in a washbasin cabinet for a period of time, and tightening them is not convenient because the nut is located inside the washbasin cabinet. Utility Model Content

[0004] To solve the above-mentioned technical problems, this utility model provides a fast-heating constant temperature preheating antifreeze electric water faucet, which solves the problem that although the existing faucets can heat water, they require high water pressure to heat water, and the heating effect is not obvious when the water pressure is too low, resulting in low practicality; the existing devices are prone to loosening after being installed in the washbasin cabinet for a period of time, and the adjustment is not convenient when tightening because the nut is located inside the washbasin cabinet.

[0005] The purpose and effect of this utility model of a fast-heating, constant-temperature preheating, and antifreeze electric water faucet are achieved by the following specific technical means:

[0006] A fast-heating, constant-temperature preheating, antifreeze electric water faucet includes an electric water faucet; a drain pipe is fixed to the top of the electric water faucet by a screw, and the drain pipe is connected to the electric water faucet; a control panel is installed on the electric water faucet, and the control panel is electrically connected to an external power source; a heating element is installed inside the electric water faucet, and an adjustment switch is provided on the control panel; a Hall switch is fixed inside the electric water faucet, and the Hall switch is electrically connected to the control panel and the heating element; a heating element is installed inside the electric water faucet, and the heating element is electrically connected to an external power source; a one-way valve and a flow shaft are installed inside the electric water faucet, with the flow shaft located below the Hall switch and the one-way valve located below the flow shaft.

[0007] Furthermore, the heating element is a PTC heating element.

[0008] Furthermore, the electric water faucet is equipped with a fixing component, which consists of a stop, a first nut, a rubber pad, a second nut, an adjustment hole, an adjustment groove, and an auxiliary rod. A ring-shaped stop is welded to the outer wall of the electric water faucet, and a first nut is threaded onto the electric water faucet. The top surface of the first nut contacts the bottom surface of the stop, and a ring-shaped rubber pad is attached to the bottom surface of the first nut. A second nut is threaded onto the electric water faucet and is located below the rubber pad.

[0009] Furthermore, the first nut has a ring structure, and adjustment holes are arranged in a ring array on the outer wall of the first nut. The adjustment holes are circular holes.

[0010] Furthermore, the outer wall of the first nut is provided with adjustment grooves in a ring array, and the adjustment grooves are rectangular groove structures.

[0011] Furthermore, the bottom surface of the second nut is welded with auxiliary rods in a ring array, and the auxiliary rods are cylindrical rod-shaped structures.

[0012] Compared with the prior art, the present invention has the following beneficial effects:

[0013] In terms of heating function, the electric water faucet has a built-in heating element and heating element. A Hall effect switch, in conjunction with the control panel, automatically activates the heating element when water flows, enabling heating of water at any pressure, overcoming the water pressure limitations of traditional devices. Meanwhile, the PTC heating element not only provides constant temperature heating for the water inside the faucet, achieving preheating and freeze protection, but also boasts high heating efficiency, ensuring users can quickly obtain hot water at a suitable temperature.

[0014] In terms of installation and fixation, the fixing components are cleverly designed. The stop, first nut, rubber washer, and second nut form a stable installation structure. During installation, first tighten the first nut, then pass it through the installation position and tighten the second nut. If the second nut becomes loose, turning the first nut will still secure the electric water faucet. Furthermore, the adjustment holes and grooves on the outer wall of the first nut facilitate adjustment using a cylindrical screwdriver or a flathead screwdriver. The auxiliary rod welded to the bottom of the second nut allows the user to hold the auxiliary rod and turn the second nut by hand when a wrench is unavailable, greatly improving the convenience and flexibility of adjustment, ensuring a stable faucet installation and easy future maintenance and adjustment.

[0028] This utility model provides a fast-heating, constant-temperature preheating, and antifreeze electric water faucet, including an electric water faucet 1; a drain pipe 101 is fixed to the top of the electric water faucet 1 by a screw, and the drain pipe 101 is connected to the electric water faucet 1; a control panel 2 is installed on the electric water faucet 1, and the control panel 2 is electrically connected to an external power supply; a heating element 4 is installed inside the electric water faucet 1; an adjustment switch 201 is provided on the control panel 2, and the adjustment switch 201 is used to control the flow of water at the electric water faucet 1 (this is prior art); a heating element 4 is fixed inside the electric water faucet 1. Hall switch 5 is electrically connected to control panel 2 and heating element 4. When water flows, Hall switch 5 sends a signal to control panel 2, which then turns on heating element 4. At this time, heating element 4 heats the water flow. Compared with existing devices, it can heat water at any pressure. Heating element 6 is installed inside electric water faucet 1 and is electrically connected to an external power source. Flow shaft 7 and check valve 8 are installed inside electric water faucet 1. Flow shaft 7 is located below Hall switch 5, and check valve 8 is located below flow shaft 7.

[0029] Among them, the heating element 6 is a PTC heating element. During use, the heating element 6 can keep the water in the electric water faucet 1 at a constant temperature, achieving the effects of antifreeze and preheating. Moreover, the PTC heating element has high heating efficiency.

[0030] The electric water faucet 1 is equipped with a fixing component 3, which consists of a stop 301, a first nut 302, a rubber pad 303, a second nut 304, an adjustment hole 305, an adjustment groove 306, and an auxiliary rod 307. A ring-shaped stop 301 is welded to the outer wall of the electric water faucet 1. A first nut 302 is threaded onto the electric water faucet 1, with its top surface in contact with the bottom surface of the stop 301. A ring-shaped rubber pad 303 is attached to the bottom surface of the first nut 302. A second nut 304 is threaded onto the electric water faucet 1, located below the rubber pad 303. During installation, the first nut 302 is threaded onto the electric water faucet 1, then the electric water faucet 1 is passed through the installation position, and finally the second nut 304 is threaded onto the electric water faucet 1 and tightened. If the second nut 304 is loose and it is inconvenient to tighten it, the first nut 302 can be rotated directly to secure the electric water faucet 1.

[0031] The first nut 302 has a ring structure, and adjustment holes 305 are arranged in a ring array on the outer wall of the first nut 302. The adjustment holes 305 are circular holes. When adjusting, a cylindrical rod can be inserted into the adjustment hole 305 and rotated, which is convenient for adjustment.

When adjusting the second nut 304, if there is no wrench, the second nut 304 can be rotated by holding the auxiliary rods 307 with your hand, which is convenient and flexible.

[0035] Example 3:

[0036] Based on Example 2, the heating element 6 can also be replaced with a constant temperature heating tape or a graphene heating plate.

[0037] Working principle: During installation, the first nut 302 is threaded onto the electric water faucet 1, then the electric water faucet 1 is passed through the installation position, and finally the second nut 304 is threaded onto the electric water faucet 1 and tightened. If the second nut 304 is loose and it is not convenient to tighten the second nut 304, the first nut 302 can be rotated directly to tighten the electric water faucet 1. During use, touching the adjustment switch 201 enables water flow. When the water flows through the flow shaft 7 and contacts the Hall switch 5, the Hall switch 5 sends a signal to the control panel 2, which connects the heating element 4, which then heats the water. When not in use, the heating element 6 can maintain a constant temperature for the water in the electric water faucet 1.
