Description

Technical Field

[0001] The utility model relates to a heating tube, in particular to a heating tube of a hair curler. Background Art

[0002] Curling irons are widely used tools in modern hair styling. Their core function relies on the heating tube to heat the curling barrel or clamp quickly, evenly and stably.

[0003] like Figure 3 As shown, the current heating pipe includes a heating element, a heat-conducting bracket and an outer tube. The heating element is arranged on the heat-conducting bracket, and the heat-conducting bracket is inside the outer tube. When transferring heat, the heating element first transfers heat to the heat-conducting bracket, and then the heat-conducting bracket transfers heat to the outer tube. The above-mentioned heating pipe needs to go through a secondary heat transfer, the heat transfer efficiency is low, and the assembly cost of this heating pipe is relatively high due to the large number of components. Utility Model Content

[0004] In view of the shortcomings of the prior art, the present invention aims to provide a heating tube for a hair curler.

[0005] To achieve the above purpose, the present invention provides the following technical solution: comprising a tube body, wherein two extension plates are integrally formed in the tube body and extend to both sides of the tube, and a receiving groove for receiving the heating element is formed between the two extension plates.

[0006] By adopting the above technical solution, two extension plates are directly arranged inside the tube. These two plates extend to both sides of the inner wall of the tube, and a receiving groove is formed between the two extension plates. The heating element is directly placed and received in the groove formed by the extension plates. Compared with the secondary heat transfer path in the background art, in which the heating element first heats the heat-conducting bracket, which then heats the outer tube, the receiving groove formed by the extension plates in this solution allows the heating element to directly contact or be very close to the inner wall of the tube. This significantly shortens the heat conduction path, reduces thermal resistance and energy loss during the heat transfer process, and thus greatly improves the heat transfer efficiency, allowing the curling iron to heat faster and more evenly. At the same time, the structure is simpler and more compact. Compared with the heating tube in the background art, this solution omits the heat-conducting bracket, reduces the intermediate heat conduction link, and has higher heat conduction efficiency, reducing the assembly cost of parts.

[0007] The utility model is further configured as follows: the extension plate is arranged vertically, the upper side and the lower side of the tube body are respectively provided with inner recesses and the inner recesses are opposite to the extension plate, and the inner recesses and the extension plate form a receiving groove.

[0008] By adopting the technical scheme, the extension plate is arranged along a vertical direction relative to the pipe body axis, the upper side and the lower side wall of the pipe body are respectively concave inward to form inner recesses, the positions of the two inner recesses are opposite to the extension plate, the inner recesses jointly act with the extension plate to enclose an accommodating groove accommodating the heating element; the cooperation of the vertically arranged extension plate and the two inner recesses makes the accommodating groove jointly constituted by the two side walls of the extension plate and the inner walls of the inner recesses, which on one hand increases the effective contact area of the heating element and the pipe body, further optimizes the heat transfer efficiency and uniformity to the whole pipe body; on the other hand, the design of the inner recesses helps to more stably position and accommodate the heating element, prevents the heating element from shaking or displacing in the groove, and ensures the reliability of the thermal contact.

[0009] The utility model further sets up: the inner recess and pipe body periphery between be provided with transition arc section.

[0010] By adopting the technical scheme, the transition arc section effectively eliminates the sharp corners or stress concentration points at the connection between the inner recess and the pipe side wall, significantly improves the mechanical strength and fatigue resistance of the pipe in the connection area, is not easy to crack in the repeated thermal expansion and cold shrinkage process, enhances the durability and safety of the heating pipe; improves the heat flow in the transition area, reduces the local thermal resistance, so that the heat can be more smoothly transferred from the inner recess to the outer peripheral wall of the pipe body, which helps to further improve the uniformity of overall heating.

[0011] The utility model further sets up: the pipe is provided with the guide rod along the pipe body axial direction, is provided with the guide port on the guide rod.

[0012] By adopting the technical scheme, the setting of the guide port ensures the connection with other objects.

[0013] The utility model further sets up: the guide port is C type.

[0014] The utility model further sets up: the guide rod is perpendicular to the extension plate. DETAILED DESCRIPTION
