DETAILED DESCRIPTION

In order to more clearly understand the above-mentioned purposes, features and advantages of the present disclosure, the embodiments of the present disclosure will be further described below. It should be noted that the embodiments of the present disclosure and the features in the embodiments can be combined with each other without conflict.

In the following description, many specific details are set forth to facilitate a full understanding of the present disclosure, but the present disclosure may also be implemented in other ways different from those described herein; obviously, the embodiments in the specification are only part of the embodiments of the present disclosure, rather than all of the embodiments.

As shown in FIG1 , an embodiment of the present application provides a heat dissipation structure of a beauty instrument, which includes: a heat dissipation fan 1 , a heat dissipation module 2 , a lamp tube 4 , a filter 5 , a light-transmitting heat-conducting member 6 and a semiconductor cooling sheet 8 .

As shown in FIGS. 2-4 , the heat dissipation module 2 includes a heat dissipation portion 24 , a light reflecting portion 21 and a heat conducting portion 23 .

The reflective portion 21 is a concave structure, which can be designed into any suitable shape, for example, an arc shape.

The lamp tube 4 is arranged in the reflective part 21. When the lamp tube 4 is working, it emits pulse light, which is reflected by the reflective part 21 and emitted from the filter 5. Since a large amount of heat is generated at the moment of the pulse light emission, part of it is radiated from the filter 5 and most of it is absorbed by the reflective part 21.

The filter 5 and the light-transmitting heat-conducting member 6 are arranged in front of the lamp tube 4. The filter 5 filters the pulse light emitted by the lamp tube 4 to pass light waves of a specific wavelength. The light-transmitting heat-conducting member 6 has an icy and analgesic effect on human skin.

The cold end of the semiconductor refrigeration sheet 8 is in contact with the light-transmitting heat-conducting member 6. When the semiconductor refrigeration sheet 8 is working, the cold end of the refrigeration sheet continuously cools and transfers the heat to the light-transmitting heat-conducting member 6, further enhancing the ice-cold analgesic effect. The hot end of the semiconductor refrigeration sheet 8 is in contact with the heat-conducting portion 23. When the semiconductor refrigeration sheet 8 is working, the hot end of the refrigeration sheet continuously dissipates heat and transfers the heat to the heat-conducting portion 23. The heat dissipation portion 24 is in contact with the reflective portion 21, and the heat dissipation portion 24 is in contact with the heat-conducting portion 23. The heat absorbed by the reflective portion 21 and the heat-conducting portion 23 can be conducted to the heat dissipation portion 24. The heat dissipation portion 24 is provided with heat dissipation fins, and the heat dissipation fan 1 is arranged corresponding to the heat dissipation fins. For example, the air outlet of the heat dissipation fan 1 is arranged at a position corresponding to the heat dissipation fins. In this way, when the heat dissipation fan 1 is started, the flowing air can take away the heat of the heat dissipation portion 24.

The heat dissipation module 2 of the utility model is designed to combine the heat dissipation function with the reflector function into a whole, so that the overall structure is more convenient to install. In the overall heat dissipation solution, it can dissipate the heat absorbed by the reflective part 21 when the lamp tube 4 emits light, and can also dissipate the heat generated by the semiconductor cooling.

In some embodiments, the heat dissipation structure also includes a shell 9. The shell 9 is provided with an air inlet 93 and an air outlet 92. The air inlet 93 and the air outlet 92 can be set at any suitable position, for example, the air inlet 93 is set at the rear of the shell 9, the air outlet 92 is set at the top of the shell 9, and the light outlet 91 is set at the front of the shell 9. The air inlet of the heat dissipation fan 1 is set at a position corresponding to the air inlet 93, and the heat dissipation fins are set at a position corresponding to the air outlet 92, so that the hot air flows directly to the air outlet 92. Through the above structure, the heat of the heat dissipation module 2 can be blown away from the top, and the air sucked into the air inlet 93 is room temperature air, so the above structure can increase the heat dissipation effect. Through the above structure, the heat generated by the beauty instrument when it is working can be discharged in time to prevent the heat from being conducted to the air inlet.

In some embodiments, in addition to the air inlet 93 and the air outlet 92, the housing 9 is also provided with a light outlet 91. The air inlet 93 is arranged at the rear of the housing 9, the air outlet (92) is arranged at the top of the housing 9, the light outlet 91 is arranged at the front of the housing 9, the light-transmitting heat-conducting member 6 is arranged at the light outlet 91, and the light-transmitting heat-conducting member mounting portion 33 is clamped or abutted against the housing 9. In this way, the overall structural strength after installation can be increased.

In some embodiments, the heat dissipation portion 24 is disposed at the rear of the heat dissipation module 2 , and the heat conduction portion 23 is disposed at the bottom of the heat dissipation module 2 , so that the heat dissipation fins can be longer, thereby increasing the heat dissipation effect.

In some embodiments, the heat dissipation fins of the heat dissipation portion 24 include a first fin and a second fin. The reflective portion 21 has a reflective surface. The first fin is concave to form the reflective portion 21. For example, when the reflective portion 21 is an arc-shaped structure, the first fin is an arc-shaped concave structure matching the reflective portion 21.

The second fin forms the reflective surface at the concave structure corresponding to the reflective portion 21. As an example, the second fin may include two fins arranged on both sides of the first fin. The heat dissipation fin is a composite structure composed of the first fin and the second fin. In this way, while further increasing the focusing effect, it is possible to prevent heat from leaking from both sides of the concave structure, so that the heat is conducted to the heat dissipation module 2, preventing the housing 9 from being heated.

In some embodiments, the lamp tube 4 passes through the through hole 22 on the second fin, and both ends of the lamp tube 4 are connected to the lamp tube bracket 71 on the main control board 7. The lamp tube 4 is arranged in the cavity of the reflective part 21, and the semiconductor cooling plate 8 is connected to the main control board 7 through a wire.

In some embodiments, as shown in FIG5 , the housing 9 is further provided with a fan receiving duct 94, which connects the air inlet 93 and the air inlet of the heat dissipation fan 1, and is clamped or abutted against the heat dissipation fan 1. In this way, while increasing the stability of the overall structure, it can also ensure that the air sucked in by the heat dissipation fan 1 is room temperature air sucked in from the air inlet 93, preventing the hot air generated inside from being sucked in. Preferably, the heat dissipation fan 1 can abut against the heat dissipation fins to further improve the air circulation path and prevent the hot air generated inside from being sucked into the gap between the two. The entire air duct of the above structure does not have too many air leakage gaps from air inlet to air outlet, which can effectively improve the overall heat dissipation efficiency.

In some embodiments, as shown in FIG6 , the heat dissipation structure further includes a bracket 3. The bracket 3 includes a connecting portion 31, a filter mounting portion 32 and a light-transmitting heat-conducting member mounting portion 33.

The filter installation part 32 has a filter fixing frame adapted to the outer contour of the filter 5, and the transparent heat conductive component installation part 33 has a transparent heat conductive component fixing frame adapted to the outer contour of the transparent heat conductive component 6. These two installation parts can firmly fix the filter 5 and the transparent heat conductive component 6.

The heat dissipation module 2 is provided with a connection seat 25, and the connection portion 31 is mounted on the connection seat 25. In some embodiments, the connection portion 31 is provided with a first connection hole 311, and the connection seat 25 is provided with a second connection hole 251. The bracket 3 is detachably mounted on the heat dissipation module 2 by screws or bolts penetrating the first connection hole 311 and the second connection hole 251.

In some embodiments, the bracket 3 further includes a semiconductor cooling sheet mounting portion 34. Thus, while the filter sheet 5 and the light-transmitting heat-conducting member 6 are fixed, the semiconductor cooling sheet 8 is also fixed.

An embodiment of the present application further provides a beauty instrument, which includes the heat dissipation structure as described above.
