[0034] See also Figure 1 The utility model provides a heat dissipation structure 100 of a beauty device, including a ventilation shell 1, which is penetrated by a ventilation channel, wherein the ventilation channel includes a first ventilation section 11 and a second ventilation section 12 which are adjacently arranged, wherein a mounting portion for mounting a near-infrared light-emitting device is formed in the first ventilation section 11, and an air supply device is installed in the second ventilation section 12, wherein the extension directions of the first ventilation section 11 and the second ventilation section 12 are arranged at an angle.

[0035] In the heat dissipation structure 100 of the beauty device provided by the utility model, two adjacently arranged first ventilation sections 11 and second ventilation sections 12 are formed in the ventilation shell 1, so that the ventilation path of the ventilation duct is arranged at an angle. In the process of the second ventilation section 12 supplying air to the first ventilation section 11, the airflow will impact the first ventilation section 11 to form turbulence, thereby improving the heat dissipation effect in the first ventilation section 11. At the same time, since the first ventilation section 11 and the second ventilation section 12 are arranged at an angle, the cross-sectional area of ​​the second ventilation section 12 can be increased relative to the first ventilation section 11, and then a larger heat dissipation device can be selected in the second ventilation section 12 to further improve the heat dissipation efficiency. At the same time, it will not take up too much space. By bending, an avoidance space is formed between the two ventilation sections, so that the remaining electrical components can be arranged in the avoidance space without increasing the cross-sectional area of ​​the entire ventilation duct as a whole.

[0036] Furthermore, an installation opening 111 connected to the ventilation channel is formed on the outer side wall of the first ventilation section 11 away from the second ventilation section 12, and the installation opening 111 forms the installation portion. In this embodiment, the near-infrared light-emitting device installed in the first ventilation section 11 can emit light outward through the installation opening 111, without the need to perform light-transmitting modification on the inner side wall of the first ventilation section 11.

[0037] Furthermore, the heat dissipation structure 100 of the beauty device further includes a near-infrared light-emitting device, which is installed in the first ventilation section and arranged corresponding to the installation port, and emits near-infrared light outward from the installation port. In this embodiment, by installing the near-infrared light-emitting device in the first ventilation section 11, cold air directly flows through the near-infrared light-emitting device, which facilitates direct heat dissipation of the near-infrared light-emitting device.

[0038] For details, please refer to Figure 2 , the near-infrared light-emitting device includes a filter 21, a reflective cup 22 and a light-emitting lamp 23; the filter 21 is installed in the installation port, and is set to cover the installation port to filter the light emitted to the installation port; the reflective cup 22 is installed in the first ventilation section corresponding to the installation port, and because the filter is arranged at intervals; the light-emitting lamp 23 is arranged between the filter 21 and the reflective cup 22 to emit near-infrared light to the filter 21. In this embodiment, the light-emitting lamp emits near-infrared light, which is emitted outward through the filter 21. At the same time, the excess near-infrared light is reflected by the reflective cup 22 to ensure that all light is emitted from the installation port, to ensure the intensity of the emitted light, and to avoid light leakage.

[0039] It should be noted that the light emitting lamp 23 is a tungsten filament lamp. The light emitted by the tungsten filament lamp is converted into near-infrared light with a wavelength of 900-1800 mm after passing through a filter.

[0040] In addition, a heat conduction groove is formed on the side of the reflective cup 22 facing away from the filter 21 to increase the heat dissipation area.

[0041] In this embodiment, an adapter circuit board is further provided in the first ventilation section 11, the light-emitting lamp 23 is electrically connected to the adapter circuit board, an adapter is provided on the adapter circuit board, the adapter circuit board is electrically connected to the main circuit board through the adapter, and the adapter on the adapter circuit board is at least partially exposed to the ventilation channel.

[0042] On the other hand, see Figure 3The heat dissipation structure 100 of the beauty device further includes a heat dissipation fan 7, which is installed in the second ventilation section, and the rotation axis of the heat dissipation fan 7 is in the same direction as the extension direction of the second ventilation section. In this embodiment, heat dissipation is performed by means of a fan, which facilitates the circulation and transportation of airflow, and has a simple and reliable structure.

[0043] It should be noted that since the axis of the cooling fan 7 is in the same extension direction as the second ventilation section, the cooling fan 7 is also inclined relative to the first ventilation section. Therefore, a fan with a larger diameter can be selected without taking up too much space, so as to improve the heat dissipation effect.

[0046] In the beauty device 1000 provided by the present invention, a receiving cavity is formed in the mounting shell 8 for receiving control components such as a circuit board, and the heat dissipation structure 100 of the beauty device is disposed in the receiving cavity, so that the ventilation channel in the heat dissipation structure 100 of the beauty device can absorb the heat in the receiving cavity and send it out from the air outlet, thereby ensuring the working temperature in the beauty device 1000.

[0047] Due to the two-stage design of the ventilation channel, the fan in the ventilation channel can be installed at an angle, so that a fan with a larger fan diameter can be installed in a limited shell space, increasing the wind force and improving the heat dissipation effect. In addition, the two-stage design of the ventilation channel can leave more space between the wire interface and the inner wall of the accommodating cavity, which is convenient for installation and wiring.

[0051] Furthermore, a sealing ring is provided between the focusing ring 4 and the working port, for sealing a gap between the focusing ring 4 and the inner wall of the accommodating cavity.

In this embodiment, since the near-infrared light emitting device emits invisible light, the indicator light 5 is set to emit light to indicate that the skin rejuvenation device is in operation, so that the focusing ring can gather light to avoid light leakage.

[0053] It should be noted that the indicator light is an LED light to facilitate indication and identification.

[0054] Specifically, in this embodiment, the indicator light 5 includes a mounting light board, the mounting light board is provided with a through hole, and the through hole is arranged corresponding to the mounting opening.

[0055] On the other hand, the beauty device 1000 further includes a skin detection device 6, which is mounted on the outer wall of the first ventilation section 11 and is arranged corresponding to the working port to detect the distance between the skin and the skin. The skin detection device 6 detects the distance between the skin and the skin, thereby controlling the operation of the near-infrared light emitting device.

[0056] It should be noted that, in this embodiment, the skin detection device 6 is a capacitive non-contact sensor.

[0057] Similarly, the beauty device 100 further includes an electrode sheet 9, which is mounted on the mounting housing and is located around the working port to stimulate skin contraction.
