Specifically, as shown in fig. 5, in the embodiment of the present invention, the air guiding groove 5211 is further formed on the side wall of the frame 521 connected to the third portion 53, so as to communicate the air flow in the hollow of the frame 521 to the hollow position of the frame 531 of the third portion 53, when the heat dissipation fan 30 operates, the air guiding groove 5211 can flow to the third portion 53 through the suction force generated by the air inlet end and then be sucked into the heat dissipation fan 30 from the air inlet end.

Specifically, as shown in fig. 5, in the embodiment of the present invention, the air guiding groove 5211 is directly opposite to the connection between the heat dissipating plate 532 and the frame 531, and meanwhile, air passing grooves 5321 communicated with the air guiding groove 5211 are formed in the plurality of heat dissipating plates 532, so that the air flow drawn out from the air guiding groove 5211 can blow and dissipate heat of the plurality of heat dissipating plates 532 along the air passing grooves 5321. Meanwhile, the connection between the corresponding frame 531 and the heat dissipation plate 532 is formed, so that the heat dissipation plate 532 erected on the edge of the heat dissipation fan 30 is effectively blown by air flow, and the phenomenon of heat concentration is prevented.

Further, as shown in fig. 1 and fig. 2, in the embodiment of the present invention, the airflow is prevented from being gathered at the second portion 52, the outer housing 200 further has an auxiliary air outlet 230, and the auxiliary air outlet 230 is formed by a plurality of small through holes, so that the airflow of the second portion 52 can be discharged through the auxiliary air outlet 230.

Further, as shown in fig. 1 in combination with fig. 3, in the embodiment of the present invention, in order to prevent the heat concentration inside the depilating apparatus 1000 and ensure the stable operation of the depilating apparatus 1000, in the technical solution, the heat dissipation frame 50 further includes a fourth portion 54, the fourth portion 54 is located on one side of the third portion 53 away from the third portion 53 and extends to the surface of the voltage transformation device 600 inside the covering outer shell 200, so as to effectively transfer the heat of the voltage transformation device 600 to the third portion 53 and prevent the unstable operation phenomenon caused by the heat concentration of the voltage transformation device 600.

Specifically, in the embodiment of the present invention, the transformer device 600 and the cooling fan 30 are installed on the same side of the circuit board (not identified), so as to save the installation space, and the height of the transformer device 600 is lower than the height of the cooling fan 30, thereby avoiding the situation that the transformer device 600 is too high and contacts with external components and parts to cause short circuit, and meanwhile, the fourth portion 54 is constructed into a plate shape, and is connected with the frame body 531 of the third portion 54 by the inclined plate 55. Therefore, the heat dissipation cavity 551 is formed between the fourth portion 54 of the transformer device 600 and the inner wall of the outer housing 200, and the inclined plate 55 is disposed to make the space of the heat dissipation cavity 551 larger, thereby facilitating the heat dissipation of the transformer device 600. Meanwhile, the side wall of the frame 531 connected to the fourth section 54 is further provided with an air guide notch 5322, the inclined plate 55 is partially located at the bottom end of the air guide notch 5322, and when the heat dissipation fan 30 works, the air flow of the heat dissipation cavity 551 formed between the fourth section 54 and the inner wall of the outer housing 200 is sucked into the air guide cavity from the air guide notch 5322, so that the heat dissipation of the fourth section 54 is accelerated.

Meanwhile, in order to ensure that the fourth portion 54 is tightly attached to the transformer device 600, heat-dissipating silica gel (not shown) is further coated between the fourth portion 54 and the transformer device 600, so that heat conductivity is improved, and the phenomenon that heat conduction efficiency is low due to a virtual position is avoided. Meanwhile, a connection column (not shown) is arranged at the intersection of the inclined plate 55 and the third portion 53, and is fixedly locked with the casing of the cooling fan 30 through a locking member, so that the fourth portion 54 is pressed on the voltage transformation device 600.

Meanwhile, the voltage transformation device 600 is disposed near the cooling fan 30 and installed between the cooling fan 30 and the battery 700, so as to prevent the third portion 53 and the fourth portion 54 of the cooling rack from being connected to occupy the arrangement space through the large-sized inclined plate 55 due to the long distance. Meanwhile, the transformer device 600 is arranged close to the cooling fan 30, so that the heat concentration point is located on one side facing the cooling fan 30, and when the cooling fan 30 works, hot air is sucked to the cooling fan 30, so that heat generated by the transformer device 600 cannot be conducted to the battery 700, and the battery 700 is effectively prevented from working under a high-temperature environment to cause potential safety hazards.

Further, the battery 700 and the transformer 600 may be separated by a heat insulation filler (not shown) to prevent the heat concentration, and the heat insulation filler may be made of a porous material, such as foam, without being limited too much, so that when the heat dissipation fan 30 operates, the airflow in the space for accommodating the battery 700 may flow to accelerate the heat dissipation.
