[0038] Preferably, the first pipe body 101 is integrally formed with an installation groove 1011 for installing the Hall sensor, and the Hall sensor is installed in the installation groove 1011. In this way, the manufacturing process is simplified. At the same time, the assembly of the Hall sensor is also facilitated. When assembling the subsequent water heater 100, the water flow switch of this embodiment can be directly installed on the water heater 100, and the step of installing the sensor in the traditional way (that is, the installation of the Hall sensor can be completed at the supplier, avoiding the need for the assembly factory to additionally set up a position for assembly) can be omitted.

[0039] This embodiment also discloses a water heater 100, which includes a housing 101 and a heating device installed in the housing 101. The heating device is connected with a water flow switch, and the water flow switch is the water flow switch described above. Among them, the adjusting knob 24 of the water flow switch is located on the left or right side of the housing 101. Thus, it not only facilitates the adjustment operation, but also is different from the existing water heaters 100 on the market in appearance, which can bring a fresh visual feeling to users, that is, it caters to consumers and improves the appearance beauty.

[0040] The design focus of the present utility model is that it mainly integrates an adjusting knob on the water flow switch. For the entire water heater, the link of externally installing the adjusting knob on the water flow switch is cancelled, saving a part of the part cost and the assembly time of the downstream assembly. Secondly, by providing a perfect seal on the circumferential side of the adjusting rod, compared with the prior art, the waterproof effect and safety performance are better.

[0041] The above is only a preferred embodiment of the present utility model, and does not limit the technical scope of the present utility model.
