Description

Technical Field

[0001] The utility model relates to the technical field of hair removal devices. Background Art

[0002] A photon hair removal device uses an intense pulsed light source to perform non-invasive light irradiation on the normal epidermis, so that the light is absorbed by melanocytes in hair follicles deep in the skin, generating heat energy to burn the hair follicles and make the hair follicles enter a dormant period, thereby stopping hair growth and achieving the hair removal effect.

[0003] The existing hair removal device such as the utility model patent No. CN210962293U discloses an ice-sensation beauty hair removal device, which includes a housing and a power supply component, an IPL light-emitting component, a refrigeration component and a main board arranged in the housing. The housing includes a body part, a handheld part and a skin contact part. The power supply component is arranged in the handheld part, the main board is arranged in the body part, the IPL light-emitting component and the refrigeration component are arranged in the skin contact part, and the power supply component, the IPL light-emitting component and the refrigeration component are all electrically connected to the main board.

[0004] The existing hair removal device has the disadvantage of poor heat dissipation effect. Both the light-emitting component and the refrigeration component need to dissipate heat, but they share a common air duct. Since the heat dissipation temperatures of the light-emitting component and the refrigeration component are different, heat is mixed and mutually affected between them, resulting in poor heat dissipation effect. Summary of the Utility Model

[0005] To solve the problem of poor heat dissipation effect of the existing hair removal device in the prior art, the utility model provides a hair removal device with double air duct heat dissipation.

A light-emitting component and a cold compress component are arranged at the front end of the hair removal device main body. It is characterized in that a heat dissipation part and an air duct component are further arranged inside the hair removal device main body. The top surface of the heat dissipation part is in contact with the rear end surface of the cold compress component. A first air duct is formed between the inner side of the heat dissipation part and the outer side of the air duct component. A second air duct is formed between the top surface of the air duct component and the rear end of the light-emitting component. An air inlet of the hair removal device is arranged on one side of the hair removal device main body, and an air outlet of the hair removal device is arranged on the other side. The air inlet of the hair removal device is communicated with the inlet of the cooling fan. The outlet of the cooling fan is communicated with the inlets of the first air duct and the second air duct. The outlets of the first air duct and the second air duct are communicated with the air outlet of the hair removal device.

[0008] Preferably, the outer side of the heat dissipation member is provided with first heat dissipation fins, and the inner side of the heat dissipation member is provided with second heat dissipation fins. The side surfaces of the second heat dissipation fins are arranged along the air flow direction of the first air duct.

[0013] The beneficial effects of the present utility model are as follows: The hair remover of the present utility model forms two air ducts through the ingenious combination of the heat dissipation member and the air duct assembly. The two air ducts respectively dissipate heat from the light emitting component and the cold compress component. Since the heat dissipation temperatures of the light emitting component and the refrigeration component are different, the setting of the two air ducts can prevent the heat from being mixed and affecting each other, thereby improving the heat dissipation effect.

The top surface of the heat dissipation member is in contact with the rear end surface of the cold compress component 3 to timely conduct the heat of the cold compress component 3, so that the cold compress component 3 maintains a sufficiently low temperature. A first air duct is formed between the inner side of the heat dissipation member 9 and the outer side of the air duct assembly. A second air duct is formed between the top surface of the air duct assembly 10 and the rear end of the light-emitting component 4. A hair removal device air inlet 11 is provided on one side of the hair removal device main body, and a hair removal device air outlet 14 is provided on the other side. The hair removal device air inlet 11 communicates with the inlet of the cooling fan 5, and the outlet of the cooling fan 5 communicates with the inlet 1011 of the first air duct and also with the inlet 1021 of the second air duct.
