[0025] It should be noted that the lower surface of the partition 3 is fixed to the inner bottom wall of the base 1, and the front and rear sides of the partition 3 are fixed to the front and rear inner walls of the base 1, respectively.

[0026] For details, please refer to Figure 2To increase the heat conduction distance, the heat conduction mechanism 2 includes a first mica plate 201. The front and rear sides of the first mica plate 201 are fixed to the inner walls of the front and rear sides of the base 1, respectively. A graphene coating 202 is provided on the inner side of the first mica plate 201. An electric heating element 203 is fixed on the outer side of the first mica plate 201. A second mica plate 204 is fixed on the outer side of the electric heating element 203. A protective component is provided on the second mica plate 204.

[0027] In this embodiment, the first mica plate 201, the graphene coating 202, and the second mica plate 204 are all arc-shaped with upward openings. There are two first mica plates 201, which are symmetrically distributed about the central axis of the partition 3.

[0028] It should be noted that the protective component includes a wire tube 205, which is fixed to the inner side of the partition 3. Rock wool filler 206 is filled between the outer side of the second mica plate 204, the inner side of the base 1, and the outer side of the wire tube 205.

[0029] The number of heating elements 203 is not less than two, and they are evenly distributed between the first mica plate 201 and the second mica plate 204. Multiple connecting holes are opened on the outer side of the wire tube 205, and they are evenly distributed on the outer side of the wire tube 205.

[0030] For details, please refer to Figure 3-4 To facilitate cable management, the storage mechanism 4 includes a cable management box 401. A mounting groove 402 is provided on the right side of the base 1. The cable management box 401 is located inside the mounting groove 402 and is fixed to the base 1 by bolts. A heat dissipation vent 403 is provided on the upper surface of the cable management box 401. A cable outlet hole 404 is provided on the right side of the cable management box 401. A spring 405 is fixed inside the cable outlet hole 404, and a clamping block 406 is fixed to the other end of the spring 405.

[0031] In this embodiment, there are two mounting slots 402 and two cable management boxes 401, which are symmetrically distributed on the left and right sides of the central axis of the base 1. The distance between the two cable management boxes 401 is adapted to the length of the partition net 5.

[0032] It should be noted that each cable management box 401 has multiple heat dissipation vents 403, which are evenly distributed on the upper surface of each cable management box 401. The number of cable outlet holes 404 is no less than two, which are evenly distributed on the right side of the right cable management box 401.

[0033] It should be added that the distance between the right side of the partition 3 and the left side wall of the left cable management box 401 is adapted to the length of the first mica plate 201, and the two ends of the wire tube 205 pass through and extend into the interior of the two cable management boxes 401 respectively.

[0034] The working principle of the above embodiments is as follows:

[0035] (1) After the power cord of the device is connected to the power supply, the heating element 203 heats the first mica plate 201. The heat of the first mica plate 201 is conducted to the graphene coating 202 and the heat is conducted out. Since the first mica plate 201 and the graphene coating 202 are both arc-shaped, the heat can be conducted to a farther position, improving the heat conduction effect. The wire of the heating element 203 passes through the wire hole into the wire tube 205 and extends out through the wire tube 205. The rock wool filler 206 blocks the heat, which not only concentrates the heat at the first mica plate 201 and the second mica plate 204, but also protects the wire, so that the temperature around the wire is kept within a safe range during the heating process of the device.

[0036] (2) After the wire of the heating element 203 extends out of the wire tube 205, the wire enters the inside of the cable management box 401 and extends out from the wire outlet 404, so that it can be connected to the external power supply. Lift the clamp 406, and the length of the wire can be stretched. Adjust the length according to the power supply position. After pulling out the appropriate length, release the clamp 406. The spring 405 presses the clamp 406 on the wire with elastic force to hold the position of the wire and prevent the wire from extending out randomly and making it inconvenient to organize. When it is necessary to inspect the internal structure, the cable management box 401 can be disassembled by bolts to facilitate the inspection of the internal structure.

[0037] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
