[0032] Reference Figures 1 - 6As shown in the figure, in an embodiment of the present utility model, a skin care device is proposed, which includes a housing 200, a light source assembly 100, and a heat dissipation assembly 300. The light source assembly 100 and the heat dissipation assembly 300 are both arranged inside the housing 200. Among them, the light source assembly 100 is used to form light of a specific wavelength band to perform skin care functions on the human skin, including but not limited to hair removal, skin rejuvenation, wrinkle removal, freckle removal, etc. The housing 200 is provided with a light outlet 210 for the light emitted by the light source assembly 100 to pass through on one side of the light source assembly 100 along the second direction. The heat dissipation assembly 300 is used to dissipate heat from the light source assembly 100. The heat dissipation assembly 300 is arranged on the side of the light source assembly 100 facing away from the light outlet 210. The heat dissipation assembly 300 includes a radiator 310 and a heat dissipation fan 320. The radiator 310 has a heat dissipation channel extending along the first direction, and a plurality of heat dissipation channels are arranged at intervals along the second direction. The heat dissipation fan 320 is arranged on the inlet side of the heat dissipation channel. The housing 200 is provided with heat dissipation holes 220 on the side of the heat dissipation channel outlet. The first direction and the second direction are arranged at an angle. For example, as Figures 1 - 3 shown, the first direction is Figure 1 the X direction and its reverse direction in Figure 1 and the second direction is the Y direction and its direction in

[0033] The light source assembly 100 includes a light source mounting frame 110, a light source 120, and a filter 130. The light source mounting frame 110 further includes a first bracket 111 and a shielding member. The first bracket 111 is provided with a first mounting area. The light source 120 is fixed in the first mounting area by means including but not limited to snap connection and bolt connection. For example, the light source 120 uses an IPL lamp tube. Two snap grooves are arranged at intervals along the first direction in the first mounting area on the first bracket 111. The axial two ends of the IPL lamp tube are respectively snapped into the two snap grooves. The shielding member is located between the light source 120 and the heat dissipation holes 220, that is, the shielding member is arranged on the side of the light source 120 close to the heat dissipation holes 220 along the first direction to block the light emitted by the light source 120 in the direction of the heat dissipation holes 220. The filter 130 is arranged on the first side of the light source 120 to filter out light of a specific wavelength band.

[0034] The shielding member is arranged between the light source 120 and the heat dissipation holes 220 in the light source mounting frame 110 of the above light source assembly 100 to block the light emitted by the light source 120 towards the heat dissipation holes 220, reducing the possibility of the light passing through the heat dissipation holes 220 and out of the housing 200, which is beneficial to protecting the human eyes.

[0035] Refer to Figure 4 shown, the shielding member includes a first baffle 113. The first baffle 113 further includes a first shielding portion 1131 extending along the second direction. The first shielding portion 1131 extends from the first side of the light source 120 close to the light outlet 210 to the second side of the light source 120 along the second direction.

[0036] It can be understood that, for effective heat dissipation, there are gaps between the two length ends of the first shielding part 1131 in the second direction and the housing 200 to allow the airflow flowing through the radiator 310 to flow towards the heat dissipation holes 220. On this basis, the first baffle 113 further includes a second shielding part 1132. The second shielding part 1132 is connected to the first shielding part 1131 and is arranged at an angle. The second shielding part 1132 is located on the first side of the light source 120, and the projection of the second shielding part 1132 and the light source 120 in the second direction partially overlaps. The setting of the second shielding part 1132 can reduce the possibility of light diverging from the side of the first shielding part 1131 close to the filter 130 towards the heat dissipation holes 220. In one embodiment, the second shielding part 1132 extends in the first direction, that is, the second shielding part 1132 is arranged parallel to the light source 120.

[0037] Similarly, the light source mounting bracket 110 further includes a second baffle 114. The second baffle 114 includes a third shielding part 1141 and a fourth shielding part 1142 connected at an angle. The third shielding part 1141 is arranged on the second side of the light source 120. The fourth shielding part 1142 is arranged offset from the first shielding part 1131 in the first direction and the projection of the fourth shielding part 1142 and the first shielding part 1131 in the first direction partially overlaps, so as to cooperate with the first shielding part 1131 to form a first guiding channel 116 extending in the second direction. It can be understood that the fourth shielding part 1142 and the first shielding part 1131 are on the same side of the light source 120 in the first direction.

[0038] In one embodiment, the third shielding part 1141 extends in the first direction, the fourth shielding part 1142 extends in the second direction, and the fourth shielding part 1142 is arranged on the side of the first shielding part 1131 facing the light source 120 to increase the distance between the fourth shielding part 1142 and the housing 200, thereby increasing the possibility of gas flowing out from the heat dissipation holes 220.

[0039] Based on the setting of the second baffle 114, a second mounting area is arranged on the side of the light source mounting bracket 110 where the third shielding part 1141 faces the first mounting area. The radiator 310 is fixed in the second mounting area by means including but not limited to bolt connection and snap connection, so as to reduce the barrier between the radiator 310 and the light source assembly 100 and avoid the setting of the third shielding part 1141 and the fourth shielding part 1142 from affecting the heat dissipation effect of the radiator 310 on the light source assembly 100.

[0040] Under the cooperation of the first baffle 113 and the second baffle 114, the light emitted by the light source 120 towards the heat dissipation hole 220 can only pass through the first guiding channel 116 extending along the second direction, while the heat dissipation hole 220 extends along the first direction. Therefore, after being guided by the first guiding channel 116, the light emitted by the light source 120 forms an angle with the axial direction of the heat dissipation hole 220, further reducing the possibility of the light passing through the heat dissipation hole 220 and exiting the housing 200.

[0041] Continue to refer to Figure 4 As shown, based on the fourth shielding portion 1142 being disposed on the side of the first shielding portion 1131 facing the light source 120, the shielding member further includes a third baffle 115. The third baffle 115 includes a fifth shielding portion 1151 and a sixth shielding portion 1152 connected at an angle. The fifth shielding portion 1151 is disposed offset from the first shielding portion 1131 in the first direction and is located on the side of the first shielding portion 1131 away from the light source 120. The fifth shielding portion 1151 and the first shielding portion 1131 partially overlap in the projection along the first direction. The sixth shielding portion 1152 extends from the end connecting the fifth shielding portion 1151 towards the first shielding portion 1131. The third baffle 115 cooperates with the first shielding portion 1131 to form a second guiding channel 117, and the light undergoes a secondary reflection in the second guiding channel 117, further reducing the possibility of the light passing through the heat dissipation hole 220 and exiting the housing 200.

[0042] In one embodiment, the fifth shielding portion 1151 extends along the second direction, and the sixth shielding portion 1152 extends along the first direction.

[0043] It should be noted that there is a gap between the end face of the sixth shielding portion 1152 and the fourth shielding portion 1142, so that the airflow flowing through the radiator 310 and carrying heat can pass through the gap between the end face of the sixth shielding portion 1152 and the fourth shielding portion 1142, avoiding affecting the heat dissipation effect of the radiator 310. That is to say, the first guiding channel 116 and the second guiding channel 117 also play a role in guiding the airflow at the same time, which can reduce the possibility of the airflow carrying heat flowing through other components that need to be cooled, and improve the heat dissipation efficiency.

[0044] Specifically, the shielding member is made of a light-shielding material or the shielding member is coated with a light-shielding layer. In one embodiment, the first baffle 113, the second baffle 114, and the third baffle 115 are integrally injection-molded with the first bracket 111, and at least the side facing the light source 120 is coated with a light-shielding layer. Specifically, the first baffle 113, the second baffle 114, the third baffle 115, and the first bracket 111 are injection-molded using POM (polyoxymethylene).

[0045] In one embodiment, the light source assembly 100 further includes a reflector 140 covering the light source 120. The reflector 140 is arranged in a trough-shaped structure with the notch facing the light exit 210. Both axial ends of the light source 120 can pass through the reflector 140 to be fixed on the light source mounting bracket 110. The reflector 140 can reflect the light emitted by the light source 120, so that the light is irradiated as much as possible in the direction of the light exit 210, improving the utilization rate of the light source 120, and at the same time reducing the possibility that the light emitted by the light source 120 is irradiated in the direction of the heat dissipation holes 220.

[0046] Refer to Figure 6 As shown, the light source mounting bracket 110 further includes a second bracket 112. The second bracket 112 can cooperate with the first bracket 111 to form an accommodation space. The first installation area is located within the accommodation space, that is, the light source 120 is installed within the accommodation space. An opening is provided on one side of the accommodation space facing the first shielding portion 1131 to communicate with the first guiding channel 116, so that the air flow can smoothly flow to the first guiding channel 116.

[0047] At the same time, the reflector 140 is also located within the accommodation space. A light-transmitting opening is provided on the first side of the accommodation space where the light source 120 is located for the light to pass through the accommodation space. The setting of the accommodation space makes the light source 120 in a relatively enclosed space, further reducing the possibility that the light exits through the heat dissipation holes 220.

[0048] Refer to Figure 1 and Figure 2 As shown, the light source assembly 100 further includes a light-transmitting contact member 150. The light-transmitting contact member 150 is arranged at the light-transmitting opening of the accommodation space, and the surface of the light-transmitting contact member 150 facing away from the filter 130 passes through the light exit 210 and is flush with or slightly protrudes from the outer surface of the housing 200 to contact the skin. Specifically, the light-transmitting contact member 150 is specifically a sapphire crystal.

[0049] Specifically, a first installation groove is provided on the first bracket 111. The light-transmitting contact member 150 is installed in the first installation groove. The first installation groove has a notch facing the second bracket 112 and both sides of the first installation groove are open along the second direction. The second bracket 112 abuts against the notch of the first installation groove to form an accommodation groove.

[0050] More specifically, the radiator 310 includes a radiator body 311 and a mounting plate 312. The radiator body 311 is installed on the mounting plate 312. The mounting plate 312 is fixed to the first bracket 111 by means of screw locking, and the mounting plate 312 abuts against the surface of the second bracket 112 on the side facing away from the first bracket 111, that is, the second bracket 112 is fixed to the first bracket 111 through the mounting plate 312.

[0051] Refer to Figure 3As shown, the skin care device further includes a filter screen 400. The filter screen 400 is disposed within the housing 200 and covers the heat dissipation holes 220. The filter screen 400 can not only reduce the possibility of foreign objects entering the interior of the housing 200 through the heat dissipation holes 220, but also block the light from diverging out through the heat dissipation holes 220 to a certain extent.

[0052] Obviously, the above embodiments of the present invention are merely examples for clearly explaining the present invention, rather than limitations on the implementation manners of the present invention. For those of ordinary skill in the art, various obvious changes, re-adjustments, and substitutions can be made without departing from the protection scope of the present invention. It is not necessary and impossible to enumerate all the implementation manners here.
