[0025] In view of the technical problems described in the background art, such as Figures 1-7As shown, a novel air duct for heat dissipation of the light source of a hair removal device is provided, comprising: a main housing 1, wherein the main housing 1 has an accommodating space; a cooling fan 2, wherein the cooling fan 2 is disposed within the main housing 1 and is used to generate airflow; an air duct housing 3, wherein the air inlet of the air duct housing 3 is connected to the air outlet of the cooling fan 2; a lamp tube 4, wherein the lamp tube 4 is disposed within the air duct housing 3 and is used to emit a light beam; a reflector cup 5, wherein the reflector cup 5 is disposed behind the lamp tube 4 and reflects the light beam of the lamp tube 4 to the light emission direction; and a heat dissipation strip 6, wherein the heat dissipation strip 6 is disposed in contact with the reflector cup 5 and is used to conduct heat from the reflector cup 5; wherein the cooling fan 2 drives the airflow generated and introduces it into the air duct housing 3, and the airflow dissipates the heat generated within the air duct housing 3 to the outside.
[0026] In implementation, the main housing 1 is equipped with air inlet and air outlet. The main housing 1 contains conventional components such as circuit boards, control chips, and batteries. Since these are not improvements in this technical solution, they will not be described further and should not be interpreted as a lack of these components. The cooling fan 2 drives airflow. External cool air enters through the air inlet of the main housing 1 and exits through the air outlet of the cooling fan 2 to the air duct housing 3. The air duct housing 3 houses the lamp tube 4, reflector cup 5, and heat sink 6. During operation, the light beam generates heat. The reflector cup 5 reflects the light beam, thus generating heat at its location. Since the heat sink 6 is in contact with the reflector cup 5, it absorbs heat and heats up. The airflow from the cooling fan 2 carries the heat from the lamp tube 4, reflector cup 5, and heat sink 6 out of the main housing 1. Because the heat sink 6 absorbs heat from the reflector cup 5, it also increases the heat dissipation area, resulting in better cooling.
[0027] refer to Figure 7 As shown, the heat dissipation strip 6 includes an arc-shaped portion 7 that fits against the reflector cup 5 and a grille portion 8 that connects to the arc plate.
[0028] Preferably, the structure of the heat dissipation strip 6 adopts a combination of an arc-shaped portion 7 and a grille portion 8. In use, the arc-shaped portion 7 is made to conform to the contour of the reflector cup 5, so that it fits onto the reflector cup 5. The grille portion 8 is designed with multiple outwardly extending ridges, thereby increasing the heat dissipation area and improving heat dissipation efficiency.
[0029] Specifically, the present invention includes a filter 9, which is disposed in front of the lamp tube 4 and is used to filter the wavelength of the light beam generated by the lamp tube 4.
[0030] Specifically, this invention includes a sapphire crystal 10, which is disposed in front of the light filter 9. The sapphire crystal 10 is used to focus the light beam generated by the lamp tube 4 and to cool the temperature of the contact area. In use, the sapphire crystal 10 adheres to the user's skin, reducing the feeling of burning.
[0031] refer to Figures 5-6 As shown, it includes a cooling chip 11, the cold side of which is attached to the sapphire 10, and the cooling chip 11 is used to absorb the heat of the sapphire 10.
[0032] The cooling chip 11 can be a semiconductor cooling chip 11, with the cold side of the cooling chip 11 attached to the sapphire 10 to cool the temperature of the sapphire 10.
[0033] Specifically, the present invention also includes a radiator 12, which is positioned above the cooling fan 2, and at least a portion of the radiator 12 extends to contact the hot surface of the cooling plate 11.
[0034] Since the temperature difference between the cold and hot sides of the cooling chip 11 affects the cooling effect of the cooling chip 11, the heat of the cooling chip 11 is transferred to the heat sink 12 by connecting the heat sink 12 to the hot side of the cooling chip 11. The heat sink 12 has multiple fins, and the airflow generated by the cooling fan 2 passes through the heat sink 12 to carry away its temperature, thereby achieving cooling and heat dissipation.
[0035] The above does not limit the technical scope of this utility model. Any modifications, equivalent changes and alterations made to the above embodiments based on the technical essence of this utility model shall still fall within the scope of the technical solution of this utility model.
