DETAILED DESCRIPTION

[0025] The following will be combined with the drawings in the embodiments of this application to clearly and completely describe the technical solutions in the embodiments of this application. Obviously, the embodiments described are only part of the embodiments of this application, not all of the embodiments. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of this application.

[0026] refer to Figure 1 and Figure 2 The present application provides a light source module heat dissipation mechanism for a hair removal device, comprising a light source module 1, a heat dissipation module 2 and a heat sink 3.

[0027] The light source module 1 and the heat dissipation module 2 are arranged adjacent to each other, and the heat sink 3 is arranged above the light source module 1 and the heat dissipation module 2 and covers the light source module 1 and the heat dissipation module 2, thereby achieving the effect of transferring the heat generated by the light source module 1 to the heat sink 3 and then dissipating it by the heat dissipation module 2;

[0028] In addition, the light source module 1 is provided with a cavity 11 , and the heat sink 3 is inserted into the cavity 11 , thereby achieving a fixing effect of the heat sink 3 .

[0029] As described in the above embodiment, the light source module 1 and the heat dissipation module 2 are arranged adjacent to each other, and the heat dissipation fin 3 covers the light source module 1 and the heat dissipation module 2. When the light source module 1 is in operation, the heat generated can be conducted to the heat dissipation fin 3 and dissipated by the heat dissipation module 2.

[0030] It can be understood that the heat sink 3 covers the air inlet of the heat dissipation module 2. When the heat generated by the operation of the light source module 1 is conducted to the heat sink 3, the cooling air inhaled by the heat dissipation module 2 through the air inlet can first pass through the heat sink 3, thereby achieving the corresponding heat dissipation effect.

[0031] In addition, the light source module 1 is provided with a cavity 11 , and the heat sink 3 is fixed above the light source module 1 through the cavity 11 and covers the heat dissipation module 2 , thereby achieving a corresponding heat dissipation effect.

[0032] Through the above structure, this embodiment achieves the effect of cooling air sucked in by the heat dissipation module by setting a heat sink covering the air inlet of the heat dissipation module, which can first pass through the heat sink for heat dissipation. This solves the problem in the prior art that the heat dissipation structure of the existing hair removal device is relatively complex, resulting in unsatisfactory heat dissipation effect, simplifies the heat dissipation structure of the hair removal device and enhances the heat dissipation effect.

[0033] refer to Figure 1 and Figure 2 In one embodiment, an air outlet 21 is provided on one side of the heat dissipation module 2, and a heat dissipation outlet 12 is provided on one side of the light source module 1;

[0034] One end of the cavity 11 is connected to the air outlet 21 , and the other end of the cavity 11 is connected to the heat dissipation port 12 , so that the cooling air blown into the air outlet 21 passes through the heat sink 3 and is blown out from the heat dissipation port 12 , thereby achieving a heat dissipation effect.

[0035] As described in the above embodiment, an air outlet 21 is provided on one side of the heat dissipation module 2, and a heat dissipation port 12 is provided on one side of the light source module 1. When the heat dissipation module 2 is operating normally, the corresponding cooling air can be inhaled through the above air inlet. It can be understood that since the heat sink 3 covers the air inlet of the heat dissipation module 2, the heat sink 3 can be cooled for the first time when the cooling air is inhaled, and then the cooling air enters the cavity 11 from the air outlet 21 and is discharged from the heat dissipation port 12. It can be understood that since the heat sink 3 is fixed in the cavity 11, the cooling air can cool the heat sink 3 for a second time when entering the cavity 11, thereby achieving the effect of secondary heat dissipation.

[0036] refer to Figure 1 In one embodiment, the light source module 1 includes an upper cover 13, a lower cover 14, a laser module 15, a cooling module 16 and a conductive medium 17;

[0037] The upper cover 13 is provided with a mounting opening. When the upper cover 13 is matched and fixed on top of the lower cover 14, the mounting opening is combined into a cavity 11. The laser module 15 is arranged at the front end of the cavity 11 and is connected to an external power supply. The conductive medium 17 is arranged at the front end of the laser module 15. The cooling module 16 is arranged on the top surface of the conductive medium 17 and is connected to the external power supply.

[0038] As described in the above embodiment, both the upper cover 13 and the lower cover 14 are provided with a mounting opening. It can be understood that the laser module 15, the cooling module 16 and the conductive medium 17 are all arranged between the upper cover 13 and the lower cover 14. Therefore, when the upper cover 13 is matched and fixed on top of the lower cover 14, the laser module 15, the cooling module 16 and the conductive medium 17 are all clamped and fixed. At the same time, the two upper and lower mounting openings form a cavity 11. At this time, the laser module 15 is arranged at the front end of the cavity 11 and is connected to an external power supply, so that when power is turned on, a laser beam for hair removal is transmitted. The laser beam passes through the conductive medium 17 and irradiates the user's skin, thereby achieving the corresponding hair removal effect. At the same time, the cooling module 16 is attached to the conductive medium 17, thereby reducing the temperature of the conductive medium 17 that rises when transmitting the laser beam, thereby avoiding burns to the user.

[0039] In one embodiment, the conductive medium 17 is made of sapphire.

[0040] As described in the above embodiment, the conductive medium 17 is made of sapphire, thus ensuring high light transmittance while achieving good transmission effect of the laser beam.

[0041] refer to Figure 3 In one embodiment, the laser module 15 includes a laser tube 151 and a refraction plate 152;

[0042] The positive and negative electrodes of the laser tube 151 are both connected to an external power supply. The refractive sheet 152 is curved to block the side of the laser tube 151 facing the cavity 11 , so that the laser light emitted by the laser tube 151 when it is turned on is directed toward the conductive medium 17 .

[0043] As described in the above embodiment, the positive and negative electrodes of the laser tube 151 are both connected to the external power supply, so that the laser tube 151 can be controlled to light up or go out following the transmitted power supply. At the same time, the refraction plate 152 is curved to block the side of the laser tube 151 facing the cavity 11, thereby achieving the effect of the laser tube 151 lighting up and sending a laser beam. It can be understood that at this time, the laser beam sent by the laser tube 151 toward the side of the cavity 11 will be reflected by the refraction plate 152, so that all laser beams are uniformly concentrated and irradiated onto the conductive medium 17 for hair removal.

[0044] In one embodiment, the cooling module 16 is actually a semiconductor refrigeration plate, so as to reduce the operating temperature of the conductive medium 17 after being powered on.

[0045] As described in the above embodiment, the cooling module 16 is actually a semiconductor refrigeration plate. It can be understood that the cooling module 16 with the properties of a semiconductor refrigeration plate can take away the heat stored inside the conductive medium 17 after being powered on, thereby reducing the operating temperature of the conductive medium 17 and preventing the user from being burned due to the excessive temperature of the conductive medium 17 during use.

[0046] refer to Figure 2 In one embodiment, a shielding cover 18 is provided at the air outlet of the heat dissipation port 12;

[0047] The surface of the shielding cover 18 is provided with a plurality of long strip air outlets 19 , so that the cooling air blown out from the heat dissipation opening 12 can be discharged through the shielding cover 18 while preventing foreign matter from entering the light source module 1 .

[0048] As described in the above embodiment, a shielding cover 18 is provided at the air outlet of the heat dissipation port 12 , and a plurality of long strip air outlets 19 are provided on the surface of the shielding cover 18 to prevent foreign matter from entering the light source module 1 and causing damage.

[0049] From the above embodiments, it can be seen that the greatest beneficial effect of the present application is that, by providing a heat sink covering the air inlet of the heat dissipation module, the cooling air inhaled when the heat dissipation module is exhausting air can first pass through the heat sink for heat dissipation, thereby solving the problem in the prior art that the heat dissipation structure of the existing hair removal device is relatively complex, resulting in unsatisfactory heat dissipation effect, simplifying the heat dissipation structure of the hair removal device and enhancing the heat dissipation effect.

[0050] The technical features of the above embodiments can be combined arbitrarily. To make the description concise, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0051] The above-described embodiments merely represent several implementation methods of the present application. While the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the present application. It should be noted that a person of ordinary skill in the art may make various modifications and improvements without departing from the spirit of the present application, and these modifications and improvements fall within the scope of protection of the present application. Therefore, the scope of protection of the present application shall be determined by the appended claims.
