[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0018] Example 1, by Figures 1-3 The present invention includes an outer tube 1, with a flange cover 2 welded to the upper end of the outer tube 1. A heating element 3 is provided inside the outer tube 1. The heating element 3 includes a spiral tube 301, with an electric heating wire 302 spirally wound on the outside of the spiral tube 301. The two terminals of the electric heating wire 302 pass through the lower opening of the spiral tube 301 and exit through the upper opening. Both terminals of the electric heating wire 302 extend through to the upper part of the flange cover 2 and are connected to terminals 4. The same rubber sleeve 5 is fitted on the outside of the two terminals of the electric heating wire 302. The rubber sleeve 5 is located at the upper part of the flange cover 2. An insulating sleeve 6 is wound on the outside of the two terminals of the electric heating wire 302.

[0019] A bracket 7 is provided between the bottom of the heating element 3 and the outer tube 1. The heating element 3 is filled with thermally conductive mineral 8 on the outside and inside the outer tube 1. The filling of thermally conductive mineral 8 improves the heat transfer efficiency and speeds up the heating process.

[0020] The upper part of the electric heating wire 302 outside the winding pipe 301 is densely wound in a spiral shape, and the lower part of the electric heating wire 302 outside the winding pipe 301 is sparsely wound in a spiral shape. The upper part of the electric heating wire 302 is densely wound on the winding pipe 301, and the lower part is sparsely wound, so as to realize the gradient distribution of power, ensure the appropriate water outlet temperature, and avoid the generation of high-temperature water vapor.

[0021] The outer sleeve 1 is a copper pipe.

[0022] The winding pipe 301 is a ceramic pipe.

[0023] Working principle: when working, the electric heating wire 302 serves as a heating element. When the power is turned on, the electric current passes through the electric heating wire 302 to generate heat, converting electric energy into heat energy. The electric heating wire 302 is spirally wound outside the winding pipe 301 at different densities. This design causes the upper part of the electric heating wire 302 to be densely wound, so the resistance is relatively large, and more heat is generated. The lower part of the electric heating wire 302 is sparsely wound, so the resistance is relatively small, and less heat is generated. The gradient distribution of power helps to realize uniform control of the water outlet temperature.

[0024] The heat-conducting mineral substance 8 is filled between the heating element 3 and the outer sleeve 1. The generated heat is further transmitted to the outer sleeve 1 through the heat-conducting mineral substance 8, so that the outer sleeve 1 heats the fluid.

[0025] The heat-conducting mineral substance 8 has good heat conduction performance and can quickly transmit the heat generated by the electric heating wire 302 to the outer sleeve 1 and the fluid.

[0026] By adjusting the power distribution of the electric heating wire 302 (i.e., densely wound at the upper part and sparsely wound at the lower part), the water outlet temperature can be accurately controlled. The upper part has a large power and a fast heating speed, so the fluid is quickly heated. The lower part has a small power and a relatively slow heating speed, which helps to maintain the stability of the water outlet temperature and avoid harm to users caused by high-temperature water vapor.

[0027] In summary, the device realizes fast, uniform, and safe heating effects through the unique spiral winding design of the electric heating wire 302 and the filling of the heat-conducting mineral substance 8. In addition, by adjusting the power distribution of the electric heating wire 302, the water outlet temperature can be accurately controlled, and harm to users caused by high-temperature water vapor can be avoided.
