[0021] In order to facilitate the understanding of the present invention, the present invention will be described in more detail below with reference to the accompanying drawings, in which typical embodiments of the present invention are shown.

[0022] Example 1:

[0023] like Figure 1-5 As shown, a rechargeable electric fan of the present invention includes an electric fan body 1, and the electric fan body 1 includes a first outer shell 2 and a second outer shell 9 arranged on the outside, a ventilation hole 19 is opened on the outside of the first outer shell 2, and a mounting groove 3 is opened on the outside of the second outer shell 9, and an inner shell 25 is fixedly installed on the inside of the mounting groove 3, and a plurality of first circular holes 7 and a plurality of second circular holes 26 are respectively opened on the outside of the inner shell 25, and a battery 22 is arranged inside the inner shell 25, and a heat-conducting silicone plate 23 is symmetrically fixedly installed on the outside of the battery 22, and a heat dissipation cavity 24 is symmetrically opened on the inside of the inner shell 25, and a heat dissipation fan 21 and a plurality of heat dissipation fins 20 are fixedly installed on the inside of each heat dissipation cavity 24, and a heat dissipation fan 21 and a plurality of heat dissipation fins 20 are fixedly installed on the inside of each heat dissipation cavity 24, and one side of each heat dissipation fin 20 is in contact with the heat-conducting silicone plate 23.

[0024] like Figure 4 As shown, a filter screen 18 is fixedly installed on the inner side of the ventilation hole 19 , and the heat dissipation fins 20 are spaced apart from the first circular hole 7 .

[0025] like Figure 1 As shown, a baffle 4 is fixedly installed on the inner side of the mounting groove 3 , and a plurality of heat dissipation holes 10 are opened on the outer side of the baffle 4 to ensure the heat dissipation capacity of the battery 22 .

[0026] During implementation, by arranging a thermal conductive silicone plate 23 and a heat dissipation fin 20 on the outside of the battery 22, the heat generated by the operation of the battery 22 can be absorbed under the action of heat conduction. At the same time, by starting the heat dissipation fan 21, the speed of air circulation in the gap between the heat dissipation fin 20 and the battery 22 is accelerated, thereby improving the heat dissipation effect of the battery 22. This solves the problem that the battery 22 used in the rechargeable fan in the prior art is arranged inside the shell and a heat dissipation hole 10 is opened on the shell for heat dissipation, but such a heat dissipation method is relatively simple, resulting in poor heat dissipation effect and affecting the service life.

[0027] Example 2:

[0028] like Figure 1-5As shown, on the basis of embodiment 1, the utility model provides a technical solution: a fan rod 8 is fixedly installed inside the first outer shell 2 and the second outer shell 9, one end of the fan rod 8 is sleeved with a connecting sleeve 14, the upper end of the connecting sleeve 14 is fixedly connected to a connecting seat 6, a machine head 5 is provided on one side of the connecting seat 6, and a limiting groove 16 is symmetrically provided on the inner side of the connecting sleeve 14, and a limiting block 15 symmetrically fixedly installed on the outer side of the fan rod 8 is symmetrically connected to the limiting groove 16. Two second positioning holes 17 are provided on the outer side of the fan rod 8, and two first positioning holes 11 and two tension springs 12 are respectively provided on the outer side of the connecting sleeve 14. One end of the two tension springs 12 is fixedly connected with a positioning member 13 that passes through the first positioning hole 11, and both ends of the positioning member 13 are plugged into the second positioning hole 17. The positioning member 13 has a U-shaped structure, and the positioning member 13 is located inside the tension spring 12.

[0029] During implementation, the machine head 5 and the fan rod 8 are connected by a limit block 15, a limit groove 16, a connecting seat 6 and a connecting sleeve 14, and the elastic tension of the tension spring 12 is used to ensure that the two ends of the positioning member 13 connected thereto are inserted and fixed inside the second positioning hole 17 opened on the fan rod 8, thereby facilitating the disassembly and assembly of the machine head 5 and subsequent maintenance work.

[0030] When assembling the machine head 5, the present technical solution first pulls the positioning member 13 on the outside of the connecting sleeve 14 to stretch the tension spring 12. Then, the connecting sleeve 14, which is connected to the assembly machine head 5 via the connecting seat 6, is sleeved on the outside of the fan rod 8. At this time, the limiting block 15 connected to the fan rod 8 is inserted into the limiting groove 16 provided in the connecting sleeve 14. At the same time, the positioning member 13 is released. At this time, under the elastic tension of the tension spring 12, the two ends of the positioning member 13 are inserted and fixed into the inside of the second positioning hole 17. When in use, the heat dissipation fan 21 is started, and air enters the interior of the mounting groove 3 through the first circular hole 7, the ventilation hole 19, and the second circular hole 26, taking away the heat absorbed by the thermal conductive silicone plate 23 and the heat dissipation fins 20 from the battery 22 and discharging it through the heat dissipation hole 10.

[0031] Although the 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 variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
