[0022] 1 to 6, an embodiment of the present invention provides a skin care device including a case 200, a light source module 100, and a heat dissipation module 300, the light source module 100 and the heat dissipation module 300 are all installed in the case 200, among which, the light source module 100 is used to form a light beam of a specific wavelength band to perform skin care functions on human skin, including but not limited to hair removal, skin rejuvenation, wrinkle removal, blemish removal, etc., and the case 200 is provided at a position on one side of the light source module 100 along the second direction, The light source module 100 has a light outlet 210 through which light emitted from the light source module 100 passes, and the heat dissipation module 300 is used to dissipate heat from the light source module 100 and is provided on one side of the light source module 100 facing away from the light outlet 210. The heat sink 310 has a heat dissipation passage extending along a first direction, and a plurality of heat dissipation passages are provided at intervals along a second direction. The heat dissipation fan 320 is provided at the inlet side of the heat dissipation passage, and the case 200 has a heat dissipation hole 220 at a position located at the outlet side of the heat dissipation passage. The first direction is provided at an angle to the second direction. For example, as shown in Figs. 1 to 3, the first direction is the X direction in Fig. 1 and the opposite direction, the second direction is the Y direction in Fig. 1 and the opposite direction, and the first direction is perpendicular to the second direction.

[0023] The light source module 100 comprises a light source mounting frame 110, a light source 120 and a filter 130. The light source mounting frame 110 further comprises a first holder 111 and a blocking member. The first holder 111 is provided with a first mounting area, and the light source 120 is fixed in the first mounting area by adopting a method including, but not limited to, fastening or bolt connection. For example, the light source 120 adopts an IPL lamp tube, and the first holder 111 is provided with two fastening grooves spaced apart along a first direction at a position located in the first mounting area, and both axial ends of the IPL lamp tube are respectively fastened in the two fastening grooves. The blocking member is located between the light source 120 and the heat dissipation hole 220, i.e., on the side of the light source 120 closer to the heat dissipation hole 220 along the first direction, and is used to block light rays emitted from the light source 120 in the direction of the heat dissipation hole 220, and the filter 130 is located on the first side of the light source 120 and is used to filter light rays of a specific wavelength band.

[0024] The light source mounting frame 110 in the above-mentioned light source module 100 is provided with a blocking member between the light source 120 and the heat dissipation hole 220 for blocking the light rays emitted by the light source 120 to the heat dissipation hole 220. This reduces the possibility that the light rays will exit the heat dissipation hole 220 through the case 200, which is advantageous for protecting human eyes.

[0025] Referring to FIG. 4, the blocking member includes a first blocking plate 113, which further includes a first blocking portion 1131 extending along a second direction, and the first blocking portion 1131 extends along the second direction from a first side close to the light outlet 210 of the light source 120 to a second side of the light source 120.

[0026] In order to effectively dissipate heat, there is a gap between both ends of the length of the first blocking portion 1131 along the second direction and the case 200, through which the airflow that has flowed through the heat sink 310 can flow to the heat dissipation hole 220. Based on this, it can be understood that the first blocking plate 113 further includes a second blocking portion 1132, which is connected to the first blocking portion 1131 and is provided with an angle therebetween, is located on the first side of the light source 120, and is projected along the second direction and partially overlaps with the light source 120. The installation of the second blocking portion 1132 can reduce the possibility that light rays will diverge from the side of the first blocking portion 1131 closer to the filter 130 toward the heat dissipation hole 220. In one embodiment, the second blocking portion 1132 extends along the first direction, i.e., is provided parallel to the light source 120.

[0027] Similarly, the light source mounting frame 110 further includes a second shielding plate 114, which includes a third shielding portion 1141 and a fourth shielding portion 1142 connected to each other with an angle therebetween, the third shielding portion 1141 being provided on the second side of the light source 120, and the fourth shielding portion 1142 being provided offset from the first shielding portion 1131 in the first direction and projected along the first direction to partially overlap the first shielding portion 1131, thereby forming a first guide passage 116 extending along the second direction in cooperation with the first shielding portion 1131. It can be seen that the fourth shielding portion 1142 and the first shielding portion 1131 are located on the same side of the light source 120 along the first direction.

[0028] In one embodiment, the third shielding portion 1141 extends along a first direction, and the fourth shielding portion 1142 extends along a second direction and is provided on one side of the first shielding portion 1131 facing the light source 120, thereby increasing the distance between the fourth shielding portion 1142 and the case 200 and increasing the possibility that gas will flow out through the heat dissipation hole 220.

[0029] Based on the installation of the second shielding plate 114, the light source mounting frame 110 is provided with a second mounting area at a position located on one side opposite the first mounting area of ​​the third shielding portion 1141, and the heat sink 310 is fixed within the second mounting area by adopting a method including, but not limited to, bolt connection or fastening, thereby reducing the gap between the heat sink 310 and the light source module 100, and avoiding the impact of the installation of the third shielding portion 1141 and the fourth shielding portion 1142 on the heat dissipation effect of the heat sink 310 on the light source module 100.

[0030] Due to the cooperation between the first and second shielding plates 113 and 114, the light emitted from the light source 120 toward the heat dissipation hole 220 can only pass through the first guide passage 116 extending along the second direction, while the heat dissipation hole 220 extends along the first direction, so that the light emitted from the light source 120, after being guided by the first guide passage 116, 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 case 200.

[0031] Continuing to refer to FIG. 4, based on the fact that the fourth shielding portion 1142 is provided on one side of the first shielding portion 1131 facing the light source 120, the shielding member further includes a third shielding plate 115, and the third shielding plate 115 includes a fifth shielding portion 1151 and a sixth shielding portion 1152 connected with an angle therebetween, the fifth shielding portion 1151 is offset from the first shielding portion 1131 in the first direction and is located on one side of the first shielding portion 1131 away from the light source 120, and its projection along the first direction partially overlaps with the first shielding portion 1131, and the sixth shielding portion 1152 extends in the direction of the first shielding portion 1131 from one end connected to the fifth shielding portion 1151. The third blocking plate 115 cooperates with the first blocking portion 1131 to form the second guide passage 117, and the light rays are secondarily reflected within the second guide passage 117, making it even less likely that the light rays will exit through the case 200 via the heat dissipation hole 220.

[0032] In one embodiment, the fifth blocking portion 1151 extends along the second direction and the sixth blocking portion 1152 extends along the first direction.

[0033] It should be noted that a gap exists between the end face of sixth blocking portion 1152 and fourth blocking portion 1142, which allows the airflow carrying heat that has flowed through heat sink 310 to pass through the gap between the end face of sixth blocking portion 1152 and fourth blocking portion 1142, thereby avoiding any effect on the heat dissipation effect of heat sink 310. In other words, first guide passage 116 and second guide passage 117 also simultaneously perform a guiding function for the airflow, reducing the possibility that the airflow carrying heat will flow through other elements that need to be dissipated, thereby improving heat dissipation efficiency.

[0034] Specifically, the blocking member is made of a light-blocking material or is coated with a light-blocking layer. In one embodiment, the first blocking plate 113, the second blocking plate 114, and the third blocking plate 115 are all injection molded integrally with the first holder 111, and a light-blocking layer is applied at least on the side facing the light source 120. Specifically, the first blocking plate 113, the second blocking plate 114, the third blocking plate 115, and the first holder 111 are injection molded using POM (polyoxymethylene).

[0035] In one embodiment, the light source module 100 further includes a light-reflecting cover 140 that covers the light source 120. The light-reflecting cover 140 has a groove-like structure with its groove opening facing the light outlet 210. Both axial ends of the light source 120 can pass through the light-reflecting cover 140 and be fixed to the light source mounting frame 110. The light-reflecting cover 140 can reflect the light emitted by the light source 120 so as to irradiate it in the direction of the light outlet 210 as much as possible, thereby increasing 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 will irradiate in the direction of the heat dissipation hole 220.

[0036] Referring to FIG. 6, the light source mounting frame 110 further includes a second holder 112, which can cooperate with the first holder 111 to form an accommodation space, and the first mounting area is located within the accommodation space, i.e., the light source 120 is mounted within the accommodation space, and an opening communicating with the first guide passage 116 is provided on the side of the accommodation space opposite the first blocking portion 1131, thereby allowing the airflow to flow smoothly into the first guide passage 116.

[0037] At the same time, the light reflective cover 140 is also located in the accommodating space, and a light transmission hole is provided in the accommodating space at a position located on the first side of the light source 120, for the light to pass through and exit the accommodating space. Due to the configuration of the accommodating space, the light source 120 is in a relatively closed space, and the possibility of the light passing through the heat dissipation hole 220 to exit is further reduced.

[0038] 1 and 2, the light source module 100 further includes a light-transmitting contact member 150, which is disposed at the light-transmitting opening of the receiving space, and the surface facing the filter 130 exits through the light exit opening 210 and is flush with the outer surface of the case 200 or slightly protrudes from the outer surface of the case 200 to contact the skin. Specifically, the light-transmitting contact member 150 is specifically a sapphire crystal.

[0039] Specifically, a first mounting groove is provided in the first holder 111, the light-transmitting contact member 150 is mounted in the first mounting groove, the first mounting groove has a groove opening facing the second holder 112 and is open on both sides along the second direction, and the second holder 112 abuts against the groove opening of the first mounting groove to form an accommodating groove.

[0040] More specifically, the heat sink 310 comprises a heat sink body 311 and a mounting plate 312, the heat sink body 311 is attached to the mounting plate 312, the mounting plate 312 is fixed to the first holder 111 by screw fastening, and the mounting plate 312 abuts against the surface of the second holder 112 facing away from the first holder 111, that is, the second holder 112 is fixed to the first holder 111 by the mounting plate 312.

[0041] Referring to FIG. 3, the skin care device further includes a filtering mesh 400, which is disposed within the case 200 and covers the heat dissipation hole 220. The installation of the filtering mesh 400 can not only reduce the possibility of foreign matter entering the inside of the case 200 through the heat dissipation hole 220, but also to a certain extent prevent light from radiating out through the heat dissipation hole 220.

[0042] Of course, the above embodiments of the present invention are merely examples given to clearly explain the present invention, and do not limit the embodiments of the present invention. Those skilled in the art can make various obvious modifications, adjustments and substitutions without departing from the scope of protection of the present invention. There is no need or method to list all the embodiments here.
