The flow control component 4 controls the flow rate of water entering the electric heating core 3, which can prevent excessive water loss from the electric heating core 3 during the preheating stage. At the same time, it can make the water temperature in the electric heating core 3 reach the user's expected temperature more quickly, which can save water resources and improve heating efficiency.

[0036] In a preferred embodiment, the flow meter 5 includes a base 51, a water passage 511 is provided inside the base 51, the water passage 511 is connected to the water inlet of the flow control component 4, an impeller 52 is provided inside the water passage 511, a magnet (not shown in the figure) is rotatably connected to the impeller 52, a Hall element 53 is provided on the outer surface of the base 51, the Hall element 53 is located next to the impeller 52, and the Hall element 53 and the magnet communicate through magnetic induction signals.

[0037] When the user turns on the faucet, cold water enters through the water passage 511 and flows through the impeller 52. The water flow will drive the impeller 52 to rotate, thereby causing the magnet to rotate. At this time, the Hall element 53 and the magnet are magnetically induced and send a signal to the flow control component 4.

[0040] Cold water enters through the water passage 511, then flows through the inlet 412, and the flow rate of water entering the receiving cavity 411 is controlled by the flow control component 4. Finally, it enters the electric heating core 3 from the outlet 413.

[0041] In a preferred embodiment, an installation groove 414 is provided at the water outlet 413, and a temperature sensor 43 is sealed at the installation groove 414.

The moving valve plate 423 is provided with a water passage hole 4231, which can be opened and closed to adjust the water passage hole 4221.

[0043] The motor 424 drives the valve plate 423 to rotate, causing the water inlet 4231 to rotate relative to the water outlet 4221. The water flow rate entering the receiving cavity 411 is proportional to the orthogonal projection coverage of the water inlet 4231 and the water outlet 4221.

[0044] In a preferred embodiment, a sealing ring 425 is provided between the static valve plate 422 and the water inlet 412.

[0045] In a preferred embodiment, the top and bottom of the inner core 3 are respectively provided with an outlet channel 31 and an inlet channel 32 communicating with the interior. The outlet 413 is connected to the inlet channel 32. A heating tube 33 is provided inside the electric heating inner core 3. A connecting base 34 is sealed to the bottom of the electric heating inner core 3. The inlet channel 32 is provided on the connecting base 34.

A nut 36 is sealed and screwed into the screw hole 341. The bottom of the nut 36 is attached to the thermostat 35.

[0046] Water flows in through the inlet channel 32 and then flows through the baffle plate 6, causing the water to flow turbulently in the electric heating core 3. The water in the electric heating core 3 is heated by the heating tube 33, and then the water is discharged out through the outlet channel 31.

[0047] The water temperature is transmitted to the thermostat 35 through the nut 36, and the thermostat 35 controls the heating element 33. The thermostat 35 detects the water temperature and controls the heating element 33 to prevent the heating element 33 from overheating.

The top of the water inlet hole 61 extends upward to a guide portion 62, and the side of the guide portion 62 is provided with a water outlet hole 63 communicating with the water outlet channel 31.

[0049] When water flows through the baffle plate 6, the water will impact the baffle plate 6, thereby reducing the flow velocity. Then the water will enter from the inlet hole 61 and flow through the guide part 62 and the outlet hole 63, thereby changing the direction of water flow and changing the laminar flow state of the water flow to turbulent flow. This device improves the self-cleaning ability of the pipe and can effectively remove scale and debris in the pipe, preventing scale and debris from accumulating in the pipe.
