[0002] To prevent bacterial growth and odors from developing when damp towels are hung, towel racks with drying functions have appeared on the market. Existing towel racks with drying functions typically include a heating wire, a heat conductor, and an outer shell for hanging towels.

[0015] This embodiment provides a heating element structure, the overall structure of which is shown in the attached diagram. Figure 1 See attached diagram for its internal structure. Figure 2 The device includes a heating wire 1, a heat conductor 2, and a housing 3. The heat conductor 2 is disposed inside the housing 3, and the heating wire 1 is fixedly disposed inside the heat conductor 2. The heat conductor 2 has a first heat conductor 21 and a second heat conductor 22. The first heat conductor 21 is tightly fitted to the upper inner wall of the housing 3, and the second heat conductor 22 is tightly fitted to the lower inner wall of the housing 3. The heat conductor 2 also comprises a first fixing part 23 and a second fixing part 24. Both the first fixing part 23 and the second fixing part 24 are semi-circular tubes. The first fixing part 23 and the second fixing part 24 cooperate with the first heat conductor 21 and the second heat conductor 22 respectively to fix the heating wire 1 inside the heat conductor 2. The inner wall of the housing 3 extends a first fastening part 31 and a second fastening part 32. The first fastening part 31 and the second fastening part 32 cooperate with the first heat conductor 21 and the second heat conductor 22 respectively to fix the heat conductor 2 inside the housing 3. Both the first fastening part 31 and the second fastening part 32 are arc-shaped extension pieces. First, the heat conductor 2 can be directly inserted into the limiting space formed by the first fastening part 31 and the second fastening part 32. Then, by applying a certain external force to the first fastening part 31 and the second fastening part 32, the first fastening part 31 and the second fastening part 32 can be bent, thereby further fastening the heat conductor 2.

The heating element structure is the heating element structure of this embodiment. The control circuit board is electrically connected to the heating wire 1 in the heating element 2. The control panel 5 is used to switch and control the temperature of the heating element.

[0019] In this embodiment, the outer shell is a hollow shell that is integrally formed. As a specific implementation, the two ends of the outer shell 3 are also provided with a front cover and a rear cover. Alternatively, the two ends of the outer shell 3 can be placed inside the bracket 4 and sealed by the bracket 4.

[0020] The beneficial effects of this embodiment are as follows: The heating element structure of this embodiment has a first heat-conducting part and a second heat-conducting part. The first heat-conducting part is tightly attached to the upper inner wall of the outer shell, and the second heat-conducting part is tightly attached to the lower inner wall of the outer shell. The heat-conducting part is attached to the inner wall of the outer shell through two heat-conducting surfaces, which improves the heat conduction efficiency and makes the heating of the outer shell more uniform, thereby improving the towel drying effect. Furthermore, the inner wall of the outer shell has a first fastening part and a second fastening part extending therefrom. The first fastening part and the second fastening part cooperate with the first heat-conducting part and the second heat-conducting part, respectively, to fix the heat-conducting part in the outer shell. First, the heat-conducting part can be directly inserted into the limiting space formed by the first fastening part and the second fastening part. Then, by applying a certain external force to the first fastening part and the second fastening part, the first fastening part and the second fastening part can be bent to further fasten the heat-conducting part. This makes the assembly method of the outer shell and the internal heat-conducting part simpler and has the advantage of high assembly efficiency.
