It can be understood that the heat dissipation member 1231 is positioned between the heat dissipation channel 122 and the air blowing element 121, so that a gap exists between the heat dissipation channel 122 and the air blowing element 121, that is, when the air flows through the heat dissipation member 1231, the air can flow out through the gap, the air flow flowing into the heat dissipation channel 122 is reduced, and the heat dissipation efficiency of the hair removal mechanism 13 is reduced. The sealing member 124 is added to seal the gap, so as to prevent the gas from leaking and improve the heat dissipation efficiency of the depilating mechanism 13.

The above is only a preferred embodiment of the present invention, and should not be limited to the present invention, and any modifications, equivalent replacements, and improvements made within the principle of the present invention should be included in the protection scope of the present invention.
