[0021] It is easy to understand that according to the technical solution of the utility model, without changing the essential spirit of the utility model, a person skilled in the art can propose a variety of interchangeable structural modes and implementation modes. Therefore, the following specific implementation modes and drawings are only exemplary descriptions of the technical solution of the utility model, and should not be regarded as the entirety of the utility model or as a limitation or restriction to the technical solution of the utility model.

[0022] like Figure 1 As shown, a modular electric heating structure includes a heating body and a heating structure, and the heating body is heated by the heating structure. In actual application, the modular electric heating structure can be connected in series and in parallel according to needs, so as to increase or decrease the resistance and realize the controllability of the resistance.

[0023] The heating structure is described below. Figure 2As shown, the heating structure includes a first heating body 4 and a second heating body 5 arranged in parallel, one end of the first heating body 4 and the second heating body 5 are fixedly connected to the electrode, and the first heating body 4 and the second heating body 5 are connected by the connecting electrode 3.

[0024] The structure of the heating element is described below. Figure 3 As shown, the heating body is composed of a ring body, a flat belt 1 and a wave belt 2. The wave belt 2 and the flat belt 1 are bonded together along the length direction and one end of the wave belt 2 and the flat belt 1 are fixed on the outer edge surface of the aforementioned ring body. With the aforementioned ring body as the center, the aforementioned assembly formed by bonding the wave belt 2 and the flat belt 1 is wound on the ring body in a spiral shape to form the heating body. Due to the influence of the force during the winding process, the width of the assembly close to one end of the aforementioned ring body gradually increases, while the width of each layer of the assembly in the middle is the same. The end of the flat belt 1 constituting the outer edge of the heating body needs to be closed, so the end of the flat belt 1 constituting the outer edge of the heating body is fixed on the outer edge surface of the flat belt 1 of the adjacent layer. The closer the wave belt 2 is to the fixed point, the smaller the width of the wave belt 2 is, so that the finally formed heating body is a circular or elliptical structure, and one end of the connecting electrode 3 in the aforementioned heating structure extends and is embedded in the ring body.

[0025] The modular electric heating structure proposed by the utility model can be connected in series to increase resistance, reduce current, and ultimately increase the service life of the heating body; and in the case of series connection, under the same resistance value requirement, the carrier is smaller, which can reduce the demand for installation space; the increase in resistance can reduce the current of the entire circuit and reduce the requirements for the circuit and the heating body. In the case of parallel connection, higher efficiency requirements can be achieved under the same diameter.

[0026] The technical scope of the present invention is not limited to the contents described above. Those skilled in the art can make various deformations and modifications to the above embodiments without departing from the technical concept of the present invention, and these deformations and modifications should all fall within the protection scope of the present invention.
