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.

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 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 this another side board 2224 is close to exhaust vent 1231, consequently, when fluorescent tube 221 worked, the partial illumination that sends can be followed lamp shade air outlet 2227 and exhaust vent 1231 and jetted out, produces the light leak phenomenon, and the normal use that some influences the user feels with experiencing.

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.

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.
