[0022] The following describes the implementation of the present invention through specific examples, and those skilled in the art can easily understand other advantages and effects of the present invention from the contents disclosed in this specification. The present invention can also be implemented or applied through other different specific implementations, and the details in this specification can also be modified or changed in various ways based on different viewpoints and applications without departing from the spirit of the present invention. It should be noted that the following embodiments and features in the embodiments can be combined with each other without conflict.

[0023] It should be noted that the illustrations provided in the following embodiments are only used to schematically illustrate the basic concept of the present invention. Therefore, the drawings only show the layers related to the present invention rather than being drawn according to the number, shape and size of the layers in actual implementation. In actual implementation, the type, quantity and proportion of each layer may be changed arbitrarily, and the layer layout may also be more complicated.

[0024] In the following description, numerous details are discussed to provide a more thorough explanation of the embodiments of the present invention; however, it is obvious to those skilled in the art that the embodiments of the present invention can be implemented without these specific details.

[0025] like Figure 1-Figure 3 As shown, the heating body in the present application includes a plurality of groups of heating tubes 1, a flange 2 and a shell 3;

[0026] The ends of the multiple groups of heating tubes 1 are fixed to the bottom surface of the flange 2, and the multiple groups of heating tubes 1 are spirally wound around a common axis;

[0027] The multiple groups of heating tubes 1 are arranged in the shell 3, and the flange 2 is fixedly connected to the top opening of the shell 3; the edge of the flange 2 is provided with multiple connecting holes, and the top opening of the shell 3 is provided with a corresponding mounting ring, and the mounting ring is provided with internal threaded holes corresponding to the multiple connecting holes. After the flange 2 is matched with the mounting ring, the flange 2 and the multiple groups of heating tubes 1 can be fixed inside the shell 3 by screwing bolts into the connecting holes and the internal threaded holes.

[0028] Specifically, the present application adopts three copper heating tubes in a spiral shape and welded together on a flange 2, which greatly reduces the volume of the heating body and the internal space of the heating body. The shell is made of industrial nylon polymer and is formed in one step by injection molding.

[0029] The shell 3 is provided with a water inlet pipe 31 and a water outlet pipe 32. The water inlet pipe 31 is provided with a pressure chamber 33. A partition 34 is provided in the pressure chamber 33. The partition 34 divides the pressure chamber 33 into an output pressure chamber 331 and a return water pressure chamber 332. The top of the output pressure chamber 331 is provided with a pressure output hole 3311 for connecting to an expansion device, and the top of the return water pressure chamber 332 is provided with a return water hole 3321 for connecting to an expansion device.

[0030] The pressure chamber is inserted with a nylon partition 34 inside, which separates the inlet pressure and return pressure into one pressure chamber, namely the output pressure chamber 331 and the return pressure chamber 332. Without consuming any energy, the natural pressure of the incoming water can generate driving force to provide driving energy to another component. For example, a water pressure switch can be driven by water pressure to achieve a mechanical start function.

[0031] A copper heating body 21 is also provided on the top surface of the flange 2, and the multiple groups of heating tubes 1 are connected to the heating body 21. The heating body 21 can be heated by a heating circuit and conduct heat to the multiple groups of heating tubes 1.

[0032] The material of the multiple groups of heating tubes 1 is oxygen-free copper, and the material of the shell 3 is industrial nylon polymer.

[0033] The side surface of the pressure chamber 33 is sealed by a cover plate 333 , and the cover plate 333 and the pressure chamber 33 are fixed by screws.

[0034] A heating body of the utility model includes multiple groups of heating tubes, a flange and a shell; the multiple groups of heating tubes are spirally wound together, which greatly reduces the volume of the heating body and the internal space of the heating body. In addition, the multiple groups of heating tubes are fixed on the flange, and then fixed to the shell through the flange. Therefore, the multiple groups of heating tubes can also be easily removed from the inside of the shell for maintenance, thereby reducing maintenance costs. In addition, a water inlet pipe and a water outlet pipe are arranged on the shell to realize cyclic heating. A pressure chamber is arranged at the water inlet pipe, and the pressure chamber is divided into an output pressure chamber and a return water pressure chamber by a partition. The pressure output hole at the top of the output pressure chamber outputs the water pressure, drives the expansion device, and returns to the return water pressure chamber through the return water hole, and is heated. Therefore, the present application also has strong expansibility.

[0035] In the above embodiments, although the utility model has been described in conjunction with the specific embodiments of the utility model, many replacements, modifications and variations of these embodiments will be apparent to those of ordinary skill in the art based on the foregoing description. The embodiments of the utility model are intended to cover all such replacements, modifications and variations that fall within the broad scope of the appended claims.

[0036] The above embodiments are merely illustrative of the principles and effects of the present invention, and are not intended to limit the present invention. Anyone familiar with the technology may modify or alter the above embodiments without departing from the spirit and scope of the present invention. Therefore, all equivalent modifications or alterations made by a person of ordinary skill in the art without departing from the spirit and technical concept disclosed in the present invention shall still be covered by the claims of the present invention.
