[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0027] Please see Figure 1-8 This utility model discloses a water flow regulating valve and a water heater, including a water flow regulating valve assembly 1. The water flow regulating valve assembly 1 includes a valve body 11, an electric isolation wall 12 disposed at one end of the valve body 11, and a fixed pipe 13 disposed at one end of the electric isolation wall 12. A flow guide tube 131 is disposed inside the fixed pipe 13, and a magnetic impeller 132 is disposed inside the flow guide tube 131. A Hall sensor 133 is disposed on one side of the fixed pipe 13, located on the side of the magnetic impeller 132. When the magnetic impeller 132 is impacted and rotated by water flow, the magnetic field changes. The Hall sensor 133 detects the change in magnetic field and can determine that there is water flow. It feeds the signal back to the main control board 28, and the main control board 28 can then start the heating chamber 27 to heat.

[0028] Specifically, one end of the valve body 11 is provided with a water inlet connector 111, and the valve body 11 is provided with a valve stem 112 inside. The valve stem 112 is provided with a valve hole 119 inside for connecting the water inlet connector 111 and the electrical isolation wall 12. The water inlet connector 111 is used to connect to a water source. When connecting to a water source, a filter screen needs to be installed inside the water inlet connector 111 to filter the water source.

[0029] Specifically, a silicone valve pad 113 is provided on one side of the valve stem 112, and a limiting groove 116 is provided at the bottom of the other side. The water inlet connector 111 is provided with an inner clamp 114 and a limiting pin 115 extending into the limiting groove 116. The limiting groove 116 and the limiting pin 115 cooperate to allow the valve stem 112 to rotate only 90 degrees, so that the valve stem 112 can only switch between the silicone valve pad 113 and the valve hole 119, reducing unnecessary rotation and making operation more convenient. The silicone valve pad 113 has a large area and can effectively seal the connection with the electrical isolation wall 12.

[0030] Specifically, the surface of the valve stem 112 is fitted with at least one sealing ring 117, and the top end of the valve stem 112 extends to the outside of the valve body 11 and is provided with a handle 118, which is used to rotate the valve stem 112.

[0031] Specifically, a small square box 134 is provided on one side of the fixed tube 13, and the Hall sensor 133 is disposed inside the small square box 134. The small square box 134 is assembled with the fixed tube 13 by snap-fit. The small square box 134 is used to install the Hall sensor 133. A thermistor can also be installed on the small square box 134 later for detection.

[0032] A water heater includes the aforementioned water flow regulating valve and a water heater assembly 2. The water heater assembly 2 includes a rear shell 21 and a glass cover 22. The water flow regulating valve assembly 1 is disposed inside the rear shell 21.

[0033] Specifically, the rear shell 21 has a plurality of first-type buckles 211 arranged around its perimeter, and the glass cover 22 has a plurality of second-type buckles 221 arranged around its perimeter, which are the same number as the first-type buckles 211 and are engaged one-to-one. The bottoms of the rear shell 21 and the glass cover 22 are fixed by locking bolts 25. The rear shell 21 and the glass cover 22 are engaged by a plurality of first-type buckles 211 and second-type buckles 221, and finally secured by a locking bolt 25. When disassembling, simply remove the locking bolt 25 and flip the glass cover 22 upward to disengage the second-type buckles 221 from the engagement of the first-type buckles 211, which facilitates later maintenance.

[0034] Specifically, a wall-mounting panel 23 is provided on one side of the rear shell 21, and at least one hook 231 is provided on one side of the wall-mounting panel 23. The rear shell 21 is provided with a connecting seat 24 that corresponds to the number of hooks 231 and engages with them one by one. The interior of the wall-mounting panel 23 is provided with at least one fixing hole 232. The wall-mounting panel 23 can be glued to the wall with adhesive or installed by drilling expansion screws into the wall and installing the wall-mounting panel 23 through the fixing hole 232. The rear shell 21 is secured to the hook 231 by the connecting seat 24, making disassembly and assembly more convenient.

[0035] Specifically, a water outlet connector 26 is provided at the bottom of the rear shell 21. An electric insulator 261 is provided at one end of the water outlet connector 26. The end of the electric insulator 261 away from the water outlet connector 26 extends into the interior of the rear shell 21 and is provided with a temperature sensor 262. Both the electric insulator 12 and the electric insulator 261 are safety protection structures for the electric water heater.

[0036] Specifically, the interior of the rear shell 21 is also provided with a heating chamber 27 and a main control board 28. The two ends of the heating chamber 27 are connected to the water inlet connector 111 and the water outlet connector 26, respectively. The heating chamber 27 is the heating chamber 27 of a common water heater on the market, and can be heated by electric heating or gas combustion.

[0037] In summary, this water flow regulating valve and water heater integrates the valve body 11, the electrical isolation wall 12, and the magnetic impeller 132 into a single water flow regulating valve assembly 1. The structure is simple and compact, making assembly with the water heater body easier and effectively preventing the risk of electric leakage and water leakage due to improper user installation. It occupies little space inside the water heater body, significantly reducing installation difficulty. The rear shell 21 and the glass cover 22 are connected by clips 211 and 221, and finally secured with a locking bolt 25. This design makes it easier to open the glass cover 22 for later maintenance. The wall mounting plate 23 can be fixed to the wall with adhesive or expansion bolts, offering multiple fixing methods to suit different installation scenarios.
