[0030] The spiral body 4 is connected with transversely arranged baffle plates 41 at both ends, respectively, and a water passing gap 41a is formed between the outer periphery of the baffle plate 41 and the inner wall of the water passing pipe 3. The baffle plate 41 is arranged to block the incoming water flow to increase the water pressure and promote the rotation of the spiral body 4. The baffle plate 41 is arranged at both ends, which facilitates installation and improves assembly efficiency.

[0031] The shell support 1 is arranged with a plurality of heating assemblies 2 at intervals.

[0032] The shell support 1 comprises end covers 11 arranged at both ends and two half shells 12, and the upper and lower ends of the half shell 12 are fixed with the end cover 11, respectively. In this way, the processing and assembly are facilitated.

[0038] Working principle:

[0039] Like the traditional instant heating body, water flows into the water inlet 3a of the water pipe 3 and flows out from the water outlet 3b of the water pipe 3, and in the process, heat is generated by the heating assembly 2, and the water in the water pipe 3 is heated through heat exchange.

[0040] The instant heating body of the utility model, which is provided with a rotatable spiral body 4 in the water pipe 3, forms a spiral water channel between the spiral body 4 and the inner wall of the water pipe 3, and the setting of the spiral body 4 increases the heat transfer area and improves the heat transfer speed and shortens the heating time. Because the water channel is spiral, the water flow time is increased to meet the heating demand, so that the length of the water pipe 3 of the instant heating body of the utility model can be shortened compared with the traditional instant heating body, thereby reducing the volume. Through testing, under the condition that the power of the heating assembly 2 is the same, the water inlet temperature is the same, and the water outlet reaches the boiling temperature, the length of the water pipe 3 of the instant heating body of the utility model can be shortened by about one third compared with the traditional instant heating body.

[0041] In addition, when the water flows through the water pipe 3, the spiral body 4 will slowly rotate under the action of water pressure, which can greatly reduce the formation of scale on the inner wall of the water pipe 3, thereby reducing the maintenance operation of scale removal and improving the service life of the instant heating body.

[0042] The above merely describes preferred embodiments of the present application, and is not intended to limit the implementation and protection scope of the present application. For those skilled in the art, it should be understood that any equivalent substitutions and obvious changes made according to the content of the present application and drawings should be included in the protection scope of the present application.
