Embodiment Construction

[0030] In order to fully understand the technical content of the present invention, the technical solution of the present invention will be further introduced and illustrated below in conjunction with schematic diagrams, but is not limited thereto.

[0031] Such as figure 1 As shown, a tube body of an electric heating tube includes: a seamless tubular body 10 . The tubular body is provided with a hollow cavity 11 and is open at one end. It adopts a one-piece structure and can be formed by metal powder injection molding, precision casting or machining. The outer periphery of the tubular body 10 is also provided with a heat dissipation structure 12, which is a circular ring or a screw thread or a tooth-shaped concave-convex structure surrounding the outer periphery of the tubular body. In this embodiment, the heat dissipation structure is a ring surrounding the outer periphery of the tube.

[0032] In this embodiment, the open end of the tubular body is also provided with a se...

Abstract

The invention discloses a body of an electric heating pipe, an electric heating pipe structure, and a manufacturing method. The body of the electric heating pipe comprises an integrated seamless tubular body provided with a hollow cavity and one open end. The periphery of the tubular body is provided with a heat dissipation structure. When the body of the electric heating pipe is used for manufacturing the electric heating pipe, a heating structure is disposed in the hollow cavity and the tubular body is a seamless integrated pipe body so that a good moisture-proof and explosion-proof effect can be achieved on the heating structure. The body of an electric heating pipe has reasonable design and good practicality and can be widely used in the market.

Description

technical field [0001] The invention relates to a daily necessities, in particular to a heating device and its structure. Background technique [0002] At present, the existing electric heating pipe body adopts welding process, and there is at least one welding seam on the pipe body, and the welding position is easily affected by moisture, resulting in pipe explosion and electric leakage, and there are safety problems. Contents of the invention [0003] In order to overcome the disadvantages of the above-mentioned prior art, the object of the present invention is to provide a tube body of an electric heating tube, a structure and a manufacturing method of the electric heating tube. [0004] Technical scheme of the present invention is: [0005] A tube body of an electric heating tube, comprising: a seamless tubular body; the tubular body is provided with a hollow cavity and one end is open, and adopts an integrated structure; the outer periphery of the tubular body is als...
