Referring to fig. 1 to 9, the embodiment of the present utility model proposes a beauty apparatus, which at least includes a housing 10, a beauty component and a heat dissipation component, wherein the beauty component and the heat dissipation component are both disposed in the housing 10, the beauty component is used for caring the skin surface of a human body, the beauty component generates heat in the housing 10 during operation, and the heat dissipation component is used for discharging the heat in the housing 10 to the outside, so as to avoid heat focusing to heat the housing 10 or burn. The heat dissipating assembly generally includes an airflow generating device and a heat sink 42, the heat sink 42 is used for receiving heat in the housing 10, and the airflow generating device is used for generating a cooling airflow and flowing the cooling airflow into the heat sink 42, so that heat on the heat sink 42 is taken away by the cooling airflow and is discharged through the air outlet 12 formed on the housing 10. It will be appreciated that the cooling air flow generated by the air flow generating device flows into the housing 10 from the outside through the air inlet hole 13 formed in the housing 10.

Alternatively, the cosmetic instrument provided by the embodiment of the present utility model may be a laser depilatory instrument, a skin tendering instrument, a whitening instrument, an ultrasonic cosmetic instrument, etc., including but not limited to, and those skilled in the art may design according to practical situations. The technical scheme provided by the embodiment of the utility model is described below by taking a dehairing instrument as an example. At this time, the cosmetic assembly may include the hair removing assembly 20 and the cold compress assembly 30, the hair removing assembly 20 may include a light source, the housing 10 may be provided with a light outlet 11, and the light source of the hair removing assembly 20 is used to emit light toward the light outlet 11 of the housing 10, and the light is received by the cold compress assembly 30 and emitted to the skin of the human body to remove hair on the skin. When the light irradiates the human skin, the human skin receives the light energy and converts the light energy into internal energy to generate heat, and in order to improve the experience of a user, the cold compress assembly 30 can be contacted with the human skin, the surface temperature of the cold compress assembly 30 is lower, and the heat sensation of the human body can be reduced when the cold compress assembly is contacted with the human body.

The cold compress assembly 30 includes a semiconductor cooling plate 31 and a lens 32, and the semiconductor cooling plate 31 has a cooling surface and a heating surface. The refrigerating surface of the semiconductor refrigerating plate 31 is connected with the lens 32, and when the semiconductor refrigerating plate 31 operates, the refrigerating surface refrigerates and conducts cold energy to the lens 32, so that the temperature of the lens 32 for contacting with human skin is relatively low to play a role in cold compress and relief on the skin, and the light emitted by the depilating component 20 is relieved to scald the skin or cause uncomfortable feeling due to relatively high temperature. When the semiconductor cooling fin 31 is operated, heat generated from the heating surface is conducted to the heat sink 42 through the heat conducting member 60. Optionally, the lens 32 comprises sapphire. That is, the heatsink 42 of the epilator is mainly used for dissipating heat from the heating surface of the semiconductor cooling fin 31. It will be appreciated that the light emitted by the epilation assembly 20 may pass through the lens 32 and impinge on the skin of a person so that the area of skin being treated is cold-laid while the epilation is being performed; the light emitted by the depilating assembly 20 can also be irradiated to the skin of a human body after passing through the periphery of the lens 32 instead of passing through the lens 32, and the lens 32 does not directly cool the region of the skin on which depilating is being performed, but rather cools the skin around the region, so that discomfort caused by high temperature of the skin can be relieved.

Optionally, in order to improve the heat dissipation effect of the dehairing instrument, an air inlet K2, a first air outlet K1 and a second air outlet K3 are formed in the radiator 42, wherein the air inlet K2 is in butt joint with the air outlet of the air flow generating device, the first air outlet K1 is arranged towards the air outlet 12 on the housing 10, the second air outlet K3 and the first air outlet K1 are located on different side walls of the radiator 42, and the second air outlet K3 is mainly used for decompressing the inside of the radiator 42 so as to ensure that cooling air flows can flow to a plurality of positions of the radiator 42 for heat exchange. During heat dissipation, the cooling air flow generated by the air flow generating device flows into the radiator 42 through the air inlet K2, wherein a part of the cooling air flow flows out of the radiator 42 through the second air outlet K3, and then flows out of the housing 10 through the air outlet 12. The other part of the cooling air flows out of the casing 10 through the first air outlet K1 after heat exchange is completed inside the radiator 42. It should be noted that, because of the arrangement of the second air outlet K3, the difference between the air pressure inside and outside the radiator 42 is reduced, so that the cooling air flow can be dispersed to various places in the radiator 42 for heat exchange after entering the radiator 42 from the air inlet K2, and then flows out of the radiator 42 from the first air outlet K1 and the second air outlet K3 respectively, thus the radiator can uniformly dissipate heat, and the local overheating or scalding situation is effectively improved.

In addition, the second air outlet K3 is mainly used for pressure relief (i.e. reducing the air pressure inside the radiator), so that the caliber of the second air outlet K3 is smaller than that of the first air outlet K1, only a small part of cooling air flows out of the radiator 42 after heat exchange through the inside of the radiator 42, and then is discharged from the air outlet 12 of the housing 10, and most of cooling air flows out of the housing 10 from the first air outlet K1 after heat exchange through the inside of the radiator 42. That is, in the embodiment in which the first air outlet K1 is directly disposed toward the air outlet hole 12 on the housing 10, the cooling air flow flowing into the radiator 42 flows out from the radiator 42 to the outside after the heat exchange is completed, and most of the cooling air flow flows out from the housing 10 directly through the air outlet hole 12 on the housing 10 after the heat exchange is completed through the radiator 42, so that the local overheating or scalding of the housing is improved, the hot air flow is accelerated to be discharged, and the heat dissipation efficiency is improved.

Alternatively, the air flow generating device may include a blower that generates cooling air to blow against the radiator 42 to radiate heat from the radiator 42.

Optionally, to further improve the heat dissipation effect of the dehairing instrument, the radiator 42 may further have a third air outlet K4, where the third air outlet K4 has the same function as the second air outlet K3, and is used for decompressing the inside of the radiator 42, so as to ensure that the cooling airflow flows more smoothly, uniformly and comprehensively. In some embodiments, the heatsink 42 of the epilator has both the second air outlet K3 and the third air outlet K4, the aperture of the third air outlet K4 being smaller than the aperture of the first air outlet K1, wherein the aperture of the third air outlet K4 may be smaller than the aperture of the second air outlet K3. When heat dissipation is performed, the cooling air flow generated by the air flow generating device flows into the radiator 42 through the air inlet K2, wherein a part of the cooling air flow flows out of the radiator 42 through the second air outlet K3, then flows out of the housing 10 through the air outlet 12, another part of the cooling air flow flows out of the radiator 42 through the third air outlet K4, then flows out of the housing 10, and a part of the cooling air flow flows out of the housing 10 through the first air outlet K1 after heat exchange is completed in the radiator 42. That is, the cooling air flow flowing into the inside of the radiator 42 flows out from the inside of the radiator 42 to the outside thereof in a split manner after the heat exchange is completed, and finally flows out to the outside of the case 10. When having second gas outlet K3 and third gas outlet K4 simultaneously, the flow of cooling air current is more smooth and easy, even and comprehensive, can make radiator 42's radiating effect obtain showing promotion, avoids appearing the phenomenon that local generates heat or send out the boiling hot to promote user experience and feel. In some embodiments, the cooling air flowing out of the radiator 42 through the third air outlet K4 may also flow back into the interior of the housing 10, and then flow into the interior of the radiator 42 by the air flow generating device.

It should be noted that although some hot air flows back into the housing 10 after the second air outlet K3 and the third air outlet K4 are opened, experiments show that the heat dissipation effect of the radiator 42 is significantly improved after the second air outlet K3 and the third air outlet K4 are opened, and compared with the hot air flowing back into the housing 10 from the second air outlet K3 and the third air outlet K4, the heat effect caused by the hot air flowing back is basically negligible.

Alternatively, referring to fig. 3 and 10, the epilator may comprise a center frame 70, which center frame 70 is distributed around the circumference of the heat sink 42 and is arranged in a substantially U-shape. One end of the middle frame 70 and the air inlet K2 of the radiator 42 are in butt joint with the air outlet of the air flow generating device, namely, the cooling air flow generated by the air flow generating device flows into the radiator 42 and the middle frame 70 in a split manner, and the other end of the middle frame 70 is communicated with the air outlet 12 on the shell 10. The epilation assembly 20 is arranged within the middle frame 70 such that heat generated by the epilation assembly 20 is carried away by a cooling air flow flowing into the middle frame 70 and discharged to the outside of the housing 10 via the air outlet holes 12 in the housing 10. That is, the cooling air flow generated by the air flow generating device may be first divided into two and respectively flow into the radiator 42 and the middle frame 70, and the cooling air flow flowing into the radiator 42 may be at least divided into two according to the actual structural design. In some embodiments, the cooling air flow generated by the air flow generating device flows into the radiator 42 and the middle frame 70 respectively in a first split manner, and the cooling air flow flowing into the radiator 42 flows into the first air outlet K1, the second air outlet K3 and the third air outlet K4 respectively in a second split manner.

Optionally, the depilatory device may further comprise a skin care assembly, in addition to the depilatory assembly 20, wherein the skin care assembly includes a skin care light, and the light emitted by the skin care light is emitted to the skin of the human body through the cold compress assembly 30, so as to achieve maintenance of the skin of the human body. When the user uses the depilatory device, the depilatory function and the skin care function of the depilatory device can be simultaneously started, that is, the skin care assembly and the depilatory assembly 20 are controlled to operate simultaneously so as to simultaneously depilation and skin care the human body. Of course, the depilating function and the skin care function of the depilating apparatus may be used independently, and the depilating function and the skin care function of the depilating apparatus may be controlled by two different keys, respectively, to control the operation and closing of the depilating assembly 20 and the skin care assembly.
