[0048] The beauty instrument according to the embodiment of the present invention will be described in detail below with reference to the accompanying drawings.

[0049] Reference Figure 1 and Figure 2 As shown, the beauty instrument provided in the embodiment of the present invention includes: an inner shell component 10, an outer shell 20, a heat dissipation mechanism 30 and a light source component 40, the inner shell component 10 defines a accommodating cavity 101; the outer shell 20 is arranged on the inner shell component 10, and together with the inner shell component 10, it forms an air inlet area P10 and a heat dissipation area P20 separated from each other, and the air inlet area P10 and the heat dissipation area P20 are both connected to the accommodating cavity 101; the heat dissipation mechanism 30 is arranged in the accommodating cavity 101, and is used to inhale the air flow into the accommodating cavity 101 through the air inlet area P10, and discharge the heat in the accommodating cavity 101 from the heat dissipation area P20; the light source component 40 is arranged on the heat dissipation mechanism 30, and is used to transfer the heat to the heat dissipation mechanism 30, so that the heat dissipation mechanism 30 discharges the heat of the light source component 40.

[0050] The beauty instrument provided by the present invention can transfer the heat generated by the light source assembly 40 to the heat dissipation mechanism 30, and through the heat dissipation mechanism 30, the external airflow is sucked into the accommodating cavity 101 through the air inlet area P10, and the heat in the accommodating cavity 101 is discharged from the heat dissipation area P20. Therefore, there is no need to set up additional heat dissipation holes, which makes the internal heat dissipation structure design simpler, improves the heat dissipation efficiency and reduces the difficulty of assembly.

[0051] Reference Figures 3 to 5As shown, the inner shell assembly 10 includes a first inner shell 11 and a second inner shell 12. The first inner shell 11 and the second inner shell 12 are fixed to each other and jointly define a accommodating cavity 101. The outer surface of the second inner shell 12 has a plurality of first protrusions 121. The plurality of first protrusions 121 are spaced apart along the length direction of the second inner shell 12 and together with the outer shell 20 form an air inlet gap so that the airflow enters the air inlet area P10 through the air inlet gap.

[0052] Among them, the first inner shell 11 and the second inner shell 12 can be fixed by snapping, or by screwing, etc., or by combining snapping and screwing, so as to simplify the assembly process; it can be understood that a heat sink and a cooling fan 32 can be installed in the accommodating cavity 101 for heat dissipation, so that the cooling fan 32 can suck the airflow into the accommodating cavity 101 for airflow replacement, thereby dissipating the heat in the accommodating cavity 101.

[0053] It can be understood that the air inlet gap can be the edge gap of the air inlet area P10. When the air is sucked into the accommodating chamber 101 through the cooling fan 32, the airflow can enter the air inlet area P10 through the air inlet gap, and then enter the accommodating chamber 101 for airflow replacement; as an optional embodiment, the first protrusion 121 can also be slidably connected in the thickness direction of the second inner shell 12. When the first protrusion 121 slides into the accommodating chamber 101, the outer shell 20 and the second inner shell 12 can be tightly fixed, thereby closing the air inlet gap. When the first protrusion 121 slides and protrudes out of the outer surface of the second inner shell 12, the outer shell 20 can be lifted by the first protrusion and the air inlet gap can be opened, so that the airflow can be sucked into the accommodating chamber 101 for heat dissipation.

[0054] Specifically, the second inner shell 12 is provided with an air inlet 122, which extends along the length direction of the second inner shell 12, and a plurality of first protrusions 121 protrude from the air inlet 122. When the airflow is sucked into the air inlet area P10 by the heat dissipation fan 32, it can enter the accommodating cavity 101 through the air inlet 122, so that the heat in the accommodating cavity 101 is discharged along with the airflow; by arranging the first protrusion 121 on the air inlet 122, the outer shell 20 can be lifted up by the first protrusion, thereby avoiding the air inlet 122 from being closed, making the air inlet gap and the air inlet 122 mutually conductive, ensuring better fluidity between the accommodating cavity 101, the air inlet 122 and the air inlet gap, and better heat dissipation effect.

[0055] Furthermore, a first air outlet 123 is provided at one end of the second inner shell 12 away from the air inlet 122 , and a second air outlet 201 corresponding to the first air outlet 123 is provided on the outer shell 20 , so that the airflow is discharged through the first air outlet 123 and the second air outlet 201 .

[0056] In this embodiment, the first air outlet 123 and the second air outlet 201 are connected to each other. When the heat in the accommodating cavity 101 is transferred to the first air outlet 123, since the heat dissipation area P20 is defined between the outer shell 20 and the second inner shell 12, the heat can be dissipated in the heat dissipation area P20 and can also be discharged from the second air outlet 201, so that the heat in the heat dissipation area P20 is not easy to accumulate and the heat dissipation effect is better.

[0057] Preferably, the outer shell 20 has a second protrusion 202, which is located in the heat dissipation zone P20 and protrudes in the direction away from the second inner shell 12; further, a shielding member 21 is provided on the second air outlet 201, and the shielding member 21 is in contact with the second protrusion 202 and forms an air outlet gap with the second air outlet 201, so that the airflow is discharged in sequence through the heat dissipation zone P20 and the air outlet gap.

[0058] In this embodiment, a third protrusion 204 is provided on the inner side of the outer shell 20 and is close to the first air outlet 123, and the third protrusion 204 is in contact with the second inner shell 12, so that an air outlet gap is also formed between the outer shell 20 and the second inner shell 12. Therefore, when the heat in the accommodating cavity 101 is discharged, the air flow can be discharged from the air outlet gap between the outer shell 20 and the second inner shell 12, or from the air outlet gap between the shielding member 21 and the second air outlet 201. It can be understood that the air outlet gap formed between the outer shell 20 and the second inner shell 12 is the edge gap of the heat dissipation zone P20. By setting multiple air outlet gaps, the heat discharge efficiency can be higher and the heat dissipation effect can be better.

[0059] Preferably, a partition 124 is provided between the air inlet 122 and the first air outlet 123, and the partition 124 extends along the width direction of the second inner shell 12, and is used to separate the airflow from between the air inlet 122 and the first air outlet 123. Among them, a plurality of partitions 124 can be provided, and they are spaced along the length direction of the second inner shell 12, so that the cold air and the hot air can be separated from each other, thereby ensuring that the airflow sucked into the accommodating cavity 101 is cold air, and preventing the exhausted hot air from being sucked into the air inlet area P10 again, and the overall structure is more compact and the heat dissipation efficiency is higher.

[0060] Reference Figures 6 to 8 As shown, the heat dissipation mechanism 30 includes: a heat dissipation bracket 31, a heat dissipation fan 32 and a cooling fin 33. The heat dissipation bracket 31 has an installation space, and the light source assembly 40 is arranged in the installation space to transfer heat to the heat dissipation bracket 31; the heat dissipation fan 32 is arranged on the heat dissipation bracket 31 to discharge the heat in the installation space; the cooling fin 33 is arranged on the heat dissipation bracket 31 and is located in the light emitting direction of the light source assembly 40.

[0061] Among them, the cooling plate 33 can be a semiconductor cooling plate 33, and the cooling end of the cooling plate 33 can be close to the patch P30 to cool the patch P30. The patch P30 can be used for applying to the skin for cold compress. For example, sapphire glass or the like can be used. By transferring the heat of the cooling plate 33 to the heat dissipation bracket 31, the heat can be concentrated on the heat dissipation bracket 31 and discharged, so that the heat dissipation effect is better and the structure is simpler; optionally, the heat dissipation bracket 31 can be made of aluminum alloy, copper, etc.; therefore, the heat generated by the light source assembly 40 and the cooling plate 33 can be transferred to the heat dissipation bracket 31, so that the heat on the heat dissipation bracket 31 can be discharged along with the heat dissipation fan 32, thereby reducing the space occupied by the overall structure, improving the heat dissipation efficiency, and having a small number of parts, simple assembly and reduced production costs.

[0062] Preferably, the heat dissipation bracket 31 includes: an air inlet portion 311, a first mounting portion 312 and a second mounting portion 313, the air inlet portion 311 is used to install the heat dissipation fan 32; the first mounting portion 312 is connected to the air inlet portion 311, and the installation space is located in the first mounting portion 312; the second mounting portion 313 protrudes along the width direction of the first mounting portion 312 and is connected to the installation space, and the cooling fin 33 is arranged on the second mounting portion 313.

[0063] In this embodiment, the first mounting portion 312 may have fins, and the air outlet direction of the cooling fan 32 is toward the first mounting portion 312, so that the heat of the light source assembly 40 is transferred to the first mounting portion 312, and the heat of the first mounting portion 312 is discharged through the cooling fan 32; it can be understood that the heat of the cooling plate 33 is transferred to the second mounting portion 313, so that the heat of the cooling plate 33 can be discharged synchronously with the airflow blown out by the cooling fan 32, so that the overall structure is simpler and the heat dissipation effect is better.

[0064] Specifically, an elastic arm 203 is provided on the shell 20, a first end of the elastic arm 203 is fixed to the shell 20, and a second end is separated from the shell 20. When the second end of the elastic arm 203 is pressed, the elastic arm 203 is deformed by the force to extend into the accommodating cavity 101.

[0065] In this embodiment, a transparent part 22 can be set on the elastic arm 203, and the elastic arm 203 can correspond to the decorative light board 23. A button can be set on the decorative light board 23. When the elastic arm 203 is pressed, the elastic arm 203 can press the button to turn on the light on the decorative light board 23 and let the light out from the gap between the elastic arm 203 and the outer shell 20, so that the transparent part 22 can illuminate with the light, which is more convenient and simple to use. It can be understood that the transparent part 22 can be fixed on the elastic arm 203. When the light needs to be turned on, the transparent part 22 can be directly pressed to drive the elastic arm 203 to be pressed to open, so that the transparent part 22 can achieve both the effect of a button and the effect of light transmission, and the overall aesthetics is better.

[0066] Reference Figure 7 and Figure 8 As shown, the light source assembly 40 includes: a first reflector 41 and a lamp tube 42, wherein the first reflector 41 is disposed in the installation space; the lamp tube 42 is disposed in the reflector and outputs a light beam in the direction of the second installation portion 313. The light beam emitted by the lamp tube 42 can be focused by the first reflector 41, so that the energy output after the photons are emitted is stronger; it can be understood that the light beam can be emitted in the direction of the above-mentioned patch P30 and irradiated onto the skin to complete beauty operations such as hair removal.

[0067] Furthermore, the second mounting portion 313 is configured with a light outlet 314, and the light beam output by the lamp tube 42 is output through the light outlet hole. The patch P30 can be arranged on the light outlet 314, so that the light beam output by the lamp tube 42 can be output to the human skin through the patch P30.

[0068] Specifically, an annular support frame 50 is provided between the second mounting portion 313 and the first mounting portion 312, and the annular support frame 50 is configured to be coaxial with the light outlet 314. Part of the annular support frame 50 may be located in the mounting space, and another part may be attached to the second mounting portion 313, so that the light beam may be output from the annular support frame 50 and the light outlet 314 in sequence.

The light emitted by the light board 70 can be reflected and focused by the second reflector 60, so that it can be focused and output toward the light outlet 314, and then its working state can be determined during operation, which is more convenient to use.

[0070] Furthermore, the inner wall of the annular support frame 50 is provided with a filter 80, and the filter 80 is located between the light board 70 and the light tube 42. The filter 80 can filter the light beam so that the output light beam can be within a specific spectrum range, and then act on the skin to achieve a better cosmetic effect; for example, it can transmit a light beam with a wavelength of 450nm-1000nm.

[0071] Specifically, the light outlet 314 is provided with a heat insulating sheet 90, and the heat insulating sheet 90 is located between the second reflector 60 and the cooling sheet 33. The heat insulating sheet 90 is provided at the light outlet 314 for heat insulation, so that when the heat dissipation fan 32 discharges the heat in the installation space, the heat generated by the lamp tube 42 can be effectively sealed in the installation space to avoid being discharged from the light outlet 314, thereby improving the cooling effect of the patch P30 during use.

[0072] Furthermore, the second mounting portion 313 is annular, and the heating end of the cooling fin 33 is fixed to the second mounting portion 313, so that the heat of the cooling fin 33 is transferred to the second mounting portion 313. The heating end of the cooling fin 33 may also be annular, and the cooling end may be circular and fixed to the patch P30 to cool the patch P30, ensuring a better cold compress effect during use, and transferring heat to the heat dissipation bracket 31, making the overall structure simpler, without the need to add a heat pipe, etc., and reducing costs.
