Description

Technical Field

[0001] This utility model is applicable to the field of beauty instruments, and in particular relates to a heat dissipation structure and a skin rejuvenation instrument. Background Technology

[0002] Photorejuvenation is an advanced high-tech beauty treatment that uses full-spectrum intense light to directly irradiate the skin surface. It can penetrate deep into the skin and selectively target subcutaneous pigments or blood vessels, breaking down pigmentation, closing abnormal red blood vessels, and eliminating various skin imperfections. At the same time, photorejuvenation can also stimulate the proliferation of subcutaneous collagen, causing the original collagen tissue to reorganize, thereby shrinking pores, reducing wrinkles, and restoring skin elasticity, health, and radiance.

[0003] When home-use phototherapy devices are in operation, the light source and filters will generate a significant temperature rise, which will affect the overall efficiency and effectiveness of the device. In addition, for scenarios where filters need to be replaced, there is a risk of burns to the user.

[0004] In addition, during the operation of the photon skin rejuvenation device, the light source will experience energy attenuation during internal transmission, which will not only cause internal temperature rise, but also affect the overall working efficiency and effect of the photon skin rejuvenation device.

[0028] in, Figure 1 and Figure 2 The reference direction coordinate system of this utility model embodiment is given below, in conjunction with Figure 1 and Figure 2 The embodiments of this utility model will be described in the directions shown.

[0029] See Figures 1-4 This utility model provides a heat dissipation structure for a skin rejuvenation device, including a light source assembly 100 and a cooling fan 200. The light source assembly 100 includes a bracket 101, a light source 102, and a filter 103. The bracket 101 has a hollow inner cavity 104. The light source 102 is disposed in the inner cavity 104 of the bracket 101. The bracket 101 has a light outlet 105 on the opposite side of the light source 102. The light outlet 105 can be designed as a circle or other shapes to guide the light from the light source 102. The filter 103 is disposed between the light source 102 and the light outlet 105, that is, the filter 103 is disposed in the optical path between the light source 102 and the light outlet 105. For example, in... Figure 1 In the illustrated embodiment, the light source 102 is located at the top of the bracket cavity 104, and the light outlet 105 is located at the bottom of the bracket cavity 104, directly opposite the light source 102. The filter 103 is positioned between the light source 102 and the light outlet 105. During operation, the light emitted from the light source 102 is filtered by the filter 103 and then emitted from the light outlet 105. The bracket 101 is provided with a ventilation opening 106, and a cooling fan 200 is connected to the ventilation opening 106, for example... Figure 1 In the embodiment shown, the vent 106 is disposed on the side wall of the bracket 101, and the cooling fan 200 is disposed on the side of the bracket 101 corresponding to the vent 106. After the cooling fan 200 is started, it can generate airflow through the inner cavity 104 of the bracket 101 to achieve cooling and heat dissipation of the light source 102, filter 103 and other components in the inner cavity 104.

[0030] Combination Figure 1 , Figure 2 , Figure 3In the technical solution of this utility model, the light source 102 and the filter 103 are disposed in the inner cavity 104 of the bracket 101. During operation, the light from the light source 102 passes through the filter 103 and is emitted from the light outlet 105. During this process, the heat generated by the light source 102 and the filter 103 during operation is dissipated by the cooling fan 200 through the inner cavity 104 of the bracket, thereby avoiding a large temperature rise in the light source 102 and the filter 103, thus improving the working efficiency and effect of the entire photon skin rejuvenation device. Moreover, for usage scenarios where the filter 103 needs to be replaced, the temperature of the filter 103 can be quickly reduced to avoid burns to the user when replacing the filter 103.

[0031] In some embodiments, see Figure 1 , Figure 2 , Figure 3 The heat dissipation structure of the skin rejuvenation device also includes a sapphire lens assembly 300. The sapphire lens assembly 300 includes a sapphire lens 301, a semiconductor cooling ring 302, and a heat sink 303. The sapphire lens 301 is located on the outer side of the light outlet 105. During use, the sapphire lens 301 is in direct contact with the skin. The sapphire lens 301 has higher light transmittance, wear resistance, and thermal conductivity. The semiconductor cooling ring 302 is located at the edge of the sapphire lens 301. During use, the side of the semiconductor cooling ring 302 closest to the sapphire lens 301 is cooled, thereby reducing the temperature of the sapphire lens 301. The lower temperature of the sapphire lens 301, when in contact with the skin, can cause the pores of the skin in contact with the sapphire lens 301 to shrink, improving the working effect of the photon skin rejuvenation device. The heat sink 303 is provided with a heat dissipation ring 304, which is in contact with the semiconductor cooling ring 302. The heat generated on the other side of the semiconductor cooling ring 302 is conducted to the heat sink 303 through the heat dissipation ring 304, and further dissipated through the heat sink 303, thereby ensuring the heat dissipation effect of the semiconductor cooling ring 302 and improving the cooling effect of the semiconductor cooling ring 302.

[0032] Furthermore, in some embodiments, see Figure 1The heat sink 303 is located at the air outlet of the cooling fan 200. After the cooling fan 200 is started, it generates airflow through the inner cavity 104 of the bracket 101, thereby cooling and dissipating heat from the light source 102, filter 103, etc. in the inner cavity 104. On the other hand, it also blows air onto the heat sink 303, accelerating the convective heat dissipation of the heat sink 303. In other words, the fan's suction accelerates convective heat dissipation, drawing away the air heat in the inner cavity 104 of the bracket, while the air blown out by the fan accelerates the airflow on the heat sink 303, thus accelerating heat dissipation. This embodiment achieves a higher heat dissipation efficiency than conventional heat dissipation structures through such a system heat dissipation scheme, thereby maintaining the operation of each system component of the instrument, controlling the duration of efficiency decay due to temperature rise, ensuring stable output of the instrument's rated energy for a long time, and quickly reducing the temperature of the filter 103 assembly to prevent burns to the user when replacing the filter 103.

[0033] In some embodiments, see Figure 4 The heat dissipation structure of the skin rejuvenation device also includes a filter holder 107, which has a light-transmitting hole. A filter 103 is disposed in the light-transmitting hole of the filter holder 107. A heat-insulating lens 108 is provided on the side of the filter 103 near the sapphire lens assembly 300. The heat-insulating lens 108 is used to reduce the heat conduction from the light source 102 to the sapphire lens assembly 300.

[0034] Among them, see Figure 4 The filter holder 107 has a reflective ring 109 on the outer periphery of the heat-insulating lens 108. The reflective ring 109 can concentrate the light from the light source 102 and reflect it onto the sapphire lens assembly 300, thereby converging more light energy, with lower attenuation, higher efficiency, lower temperature rise, and more obvious effect.

[0035] Further, see Figure 1 , Figure 4 The heat dissipation structure of the skin rejuvenation device also includes a first reflector 400, which is located between the light outlet 105 and the sapphire lens 301. The first reflector 400 converges and reflects light, which ultimately reaches the external sapphire lens assembly 300, where the converged light energy has low attenuation, high efficiency, lower temperature rise, and more obvious effects.

[0036] In some embodiments, see Figure 1 The first reflector cup 400 is mounted on the bracket 101 via the bottom frame 401. The bottom frame 401 is equipped with an ambient light 402. The first reflector cup 400 has an flared portion extending to the ambient light 402. The ambient light 402 can light up when working, emitting dazzling light to enhance the atmosphere when using the skin rejuvenation device.

[0037] In some embodiments, a heat insulation pad is provided between the bottom frame 401 and the heat dissipation ring 304, the heat insulation pad being used to reduce the conduction of heat from the light source 102 to the sapphire lens assembly 300.

[0038] Understandably, the first reflector 400 can also be connected to the bracket 101 by means of adhesive, screws, etc.

[0039] In some embodiments, see Figure 2 , Figure 3 , Figure 4 The light source 102 includes a xenon lamp. A second reflector 110 is provided on the side of the xenon lamp away from the light outlet 105. The light emitted by the xenon lamp is reflected by the second reflector 110, strikes the filter 103, and is then emitted from the light outlet 105. A heat dissipation structure 111 is provided on the back side of the second reflector 110. The heat dissipation structure 111 can dissipate the heat of the second reflector 110 into the airflow of the inner cavity 104, thereby preventing a large temperature rise in the light source 102 and the filter 103, and improving the overall efficiency and effectiveness of the photon skin rejuvenation device.

[0040] See Figure 1 , Figure 4 The optical path design principle of this device is as follows: the light energy emitted by the xenon lamp passes through the filter 103. Simultaneously, light from other directions is converged by the second reflector 110 of the xenon lamp and passes through the filter 103. The light of a specific wavelength passing through the filter 103 is amplified and reflected by the reflector ring 109 and the first reflector 400, then diffusely reflected to the sapphire cooling chip assembly before reaching the outside. This optical path design results in greater converged light energy, lower attenuation and higher efficiency, lower temperature rise, and more pronounced therapeutic effects. It solves the problems of refraction in optical instruments and energy attenuation when the xenon lamp light is converged to the outside. The low-attenuation, high-transmission-efficiency energy light helps ensure the therapeutic effect, reduces internal temperature rise, improves product durability, and enhances product competitiveness.
