The area of the first conductive member 242 is larger than that of the cooling member 241, thereby increasing the contact area with the skin, increasing the cold compress area, and thus enhancing the cold compress effect. And the cold flow of the refrigerating member 241 is transmitted to the skin through the first and second

conductive members

242 and 243, so that the refrigerating member 241 does not need to be in direct contact with the skin, thereby preventing the refrigerating member 241 from being corroded by grease, sweat and the like on the skin.

The impeller 41 is a centrifugal impeller, the heat-conducting volute 42 is provided with a volute air inlet 421 and a volute air outlet 422, the volute air inlet 421 is opposite to the air inlet 1221 of the bottom wall 122, the volute air outlet 422 is communicated with an air guide device 45, the inlet end of the air guide device 45 is communicated with the volute air outlet 422, and the outlet end of the air guide device 45 is communicated with the air outlet 1231 on the side wall 125. In the present embodiment, the air guiding device 45 is an air guiding cover, the air guiding cover is disposed on the circuit board 63 so as to surround the circuit board 63 to form an air guiding channel, and a shape of an end portion of the air guiding device 45 close to the air outlet 1231 is identical to and attached to the shape of the side wall 125. When the impeller 41 works, external air can be sucked into the heat-conducting volute 42 through the air inlet hole 1221 on the bottom wall 122 and the volute air inlet 421, then enters the air guiding device 45 through the volute air outlet 422, and finally is discharged out of the second accommodating cavity 121 through the air outlet hole 1231 on the side wall 125. When the air flows through the relevant components, for example the heat-conducting volute 42, it takes away part of the heat of the relevant components and transfers it to the environment, thereby lowering the temperature inside the epilating apparatus 1.

The volute air inlet 421 is opposite to the air inlet 1221 on the casing 10, so that the air resistance can be reduced, and the air inlet efficiency can be improved. In the embodiment of the present application, by disposing the air inlet holes 1221 on the bottom wall 122, compared with the manner of disposing the air inlet holes 1221 on the side wall 125 of the head 12, the overall height of the head 12 can be reduced, which is helpful for reducing the overall volume of the depilating apparatus 1, and is convenient for the user to use and carry; but also brings cool feeling to the hand of the user holding the depilating apparatus 1, and improves the operation experience of the user.

In this embodiment, the side of the sidewall 125 of the end cap 123 far from the air outlet 1231 is further provided with a heat dissipation hole 1232 for natural heat dissipation, and heat generated by the operation of the internal components of the hair removal device 1 can be discharged from the air outlet 1231 under the action of the impeller 41 and can be discharged through the heat dissipation hole 1232, thereby further reducing the temperature inside the hair removal device 1.

Referring to fig. 14, the lampshade 222 is disposed inside the air guiding device 45 and spaced apart from the inner wall of the air guiding device 45. The lamp housing 222 has a lamp housing inlet 2226 and a lamp housing outlet 2227, the lamp housing inlet 2226 is disposed on the side plate 2224 of the housing main body 2222 away from the air outlet 1231, and the lamp housing outlet 2227 is disposed on the side of the U-shaped reflector 2225 away from the circuit board 63. When air enters the air guiding device 45 from the volute air outlet 422, a part of air flow directly passes through a gap between the reflector 2225 and the inner wall of the air guiding device 45, and takes away part of heat of the lamp shade 222; another part of the airflow enters the interior of the lamp housing 222 through the lamp housing inlet 2226, flows through the lamp tube 221 and is exhausted from the lamp housing outlet 2227, takes away part of the heat of the lamp housing 222 and the lamp tube 221, and then reenters the gap between the lamp housing 222 and the air guiding device 45, and finally is exhausted through the air outlet 1231 on the end cover 123, so as to reduce the temperature inside the hair removal device 1.

In other embodiments, the lampshade outlet 2227 can also be disposed on the other side panel 2224 (i.e. the side panel 2224 close to the outlet hole 1231). Because the other side plate 2224 is close to the air outlet 1231, when the lamp tube 221 works, part of the light emitted from the lamp shade air outlet 2227 and the air outlet 1231 can be emitted, so that a light leakage phenomenon is generated, and the normal use and experience of a user are partially influenced.

In some embodiments, a heat sink 46 may be disposed between the side plate 2224 of the lamp housing 222 near the air outlet 1231 and the air outlet 1231, and the heat sink 46 is thermally connected to the electrode 226, i.e., the heat of the electrode 226 can be transferred to the heat sink 46. In this embodiment, the heat sink 46 is fixed to the circuit board 63 and indirectly contacts the electrode 226 through a heat conducting sheet, which may be either only thermally conductive or electrically non-conductive, or both thermally and electrically conductive, as long as the heat of the electrode 226 can be transferred to the heat sink 46 through the heat conducting sheet, thereby effectively reducing the temperature of the electrode 226. The airflow passes through the heat sink 46 before being discharged from the air outlet 1231, thereby removing heat from the heat sink 46.

Preferably, the heat sink 46 includes a plurality of fixing portions 461 fixed to the circuit board 63 and a U-shaped heat sink 462 connected between adjacent two fixing portions 461. Each heat dissipation part 462 comprises two parallel heat dissipation plates 4621 which are opposite at intervals and a connecting plate 4622 connected between the two heat dissipation plates 4621, an air flow channel is formed between the adjacent heat dissipation plates 4621, and the direction of the air flow channel is consistent with the direction of air flow in the air guide pipe as much as possible so as to reduce wind resistance. In this embodiment, the orientation of the airflow channel forms a certain angle with the axial direction of the lamp 221, and the airflow channel is inclined to the axial direction of the lamp 221 toward the air outlet 1231 by a certain angle. When the airflow flows through the heat dissipation member 46, the airflow not only contacts the outer surface of the heat dissipation member 46, but also contacts the inner surface of the heat dissipation part 462, so that the contact area between the heat dissipation member 46 and the airflow is increased, that is, the heat dissipation area of the heat dissipation member 46 is increased, and the heat dissipation effect of the heat dissipation member 46 is enhanced.

The number of the heat dissipation portions 462 is not limited, and may be one or more.

The above embodiments are only preferred embodiments of the present invention, and the protection scope of the present invention is not limited thereby, and any insubstantial changes and substitutions made by those skilled in the art based on the present invention are within the protection scope of the present invention.
