[0031] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without making creative efforts belong to the protection scope of the present utility model. Specific Embodiment 1

[0032] As Figures 1-9 shown, a skin phototherapy device proposed in this embodiment includes a skin phototherapy device 1, a heat dissipation port 2, a dust-proof structure, and a fixing structure.

[0033] As Figures 1-6 shown, a plurality of heat dissipation ports 2 provided on the skin phototherapy device 1 for heat dissipation; two symmetrically distributed dust-proof structures on the skin phototherapy device 1, which include a docking ring 3 fixedly connected to the skin phototherapy device 1, a filter cotton 4 movably connected in the docking ring 3 for dust prevention, a limiting ring 7 in contact with the docking ring 3 for restricting the movement of the filter cotton 4, and a connection structure provided on the docking ring 3 for connecting the limiting ring 7. A docking groove 8 for movably connecting the filter cotton 4 is provided on the docking ring 3.

[0034] The connection structure includes a connection block 21 fixedly connected to the docking ring 3, a connection shaft 5 rotatably connected in the connection block 21, and movable blocks 6 fixedly connected to the connection shaft 5 and the limiting ring 7 respectively.

[0035] In this embodiment, through the setting of the filter cotton 4, the air entering the skin phototherapy device 1 can be filtered, so as to avoid dust and other impurities in the external environment directly entering the interior of the skin phototherapy device 1 through the heat dissipation port 2, and avoid dust and other impurities adhering to the electrical components in the skin phototherapy device 1. Specific Embodiment 2

[0036] As Figures 1-9As shown, a skin phototherapy device proposed in this embodiment, compared with the first embodiment, in this embodiment, the fixing structure includes a connecting rod 9 fixedly connected to the limiting ring 7, a movable plate 11 rotatably connected to the connecting rod 9, a positioning block 12 fixedly connected to the docking ring 3, a limiting rod 13 fixedly connected inside the positioning block 12, a T-shaped block 14 slidably connected to the limiting rod 13, and a fixing block 15 fixedly connected to the T-shaped block 14. One end of the connecting rod 9 away from the limiting ring 7 is fixedly connected with an anti-disengagement block 10 to prevent the movable plate 11 from disengaging from the connecting rod 9. The side surface of the anti-disengagement block 10 is in contact with the movable plate 11. A torsion spring 16 for automatically rotating the movable plate 11 is arranged on the outer surface of the connecting rod 9. One end of the torsion spring 16 is fixedly connected to the outer surface of the connecting rod 9, and the other end of the torsion spring 16 is fixedly connected to the inner side wall of the movable plate 11. A spring 17 for automatically moving the T-shaped block 14 is arranged on the outer surface of the limiting rod 13. Two ends of the spring 17 are respectively fixedly connected to the side surface of the T-shaped block 14 and the inner side wall of the positioning block 12. A T-shaped groove 18 slidably connected to the limiting rod 13 is formed in the positioning block 12, a positioning groove 19 movably connected to the movable plate 11 is formed in the positioning block 12, and a fixing groove 20 movably connected to the fixing block 15 is formed in the movable plate 11.

[0037] In this embodiment, when the air permeability of the filter cotton 4 decreases after a period of use, by pulling the fixed block 15, the moving fixed block 15 can drive the T-shaped block 14 to move horizontally on the limiting rod 13. And during the movement of the T-shaped block 14, it will gradually squeeze the spring 17 on the inner wall of the positioning block 12, so that the spring 17 is in a taut state. When the moving fixed block 15 disengages from the fixed slot 20, the restriction on the torsion spring 16 is released. Then the torsion spring 16 can flip and rebound, and the flipping and rebounding torsion spring 16 can drive the movable plate 11 and the fixed slot 20 to rotate around the connecting rod 9 as the central axis. And under the action of the anti-disengagement block 10, it can prevent the movable plate 11 from disengaging from the connecting rod 9. When the rotating movable plate 11 disengages from the positioning slot 19 and no longer contacts the docking ring 3, the fixed slot 20 no longer corresponds to the fixed block 15. Then release the pulled fixed block 15, so that the spring 17 is no longer restricted by the pulling force and rebounds. The rebounding fixed block 15 can drive the T-shaped block 14 to move back to its original position in the T-shaped slot 18, so that the moving T-shaped block 14 can drive the fixed block 15 to move back to its original position. Because the fixed slot 20 no longer corresponds to the fixed block 15, the fixed block 15 will not enter the fixed slot 20. Then flip the limiting ring 7, so that the limiting ring 7, the connecting rod 9, the anti-disengagement block 10, the movable plate 11, the torsion spring 16 and the movable block 6 rotate around the connecting shaft 5 in the connecting block 21 as the central axis, thus realizing the opening of the movable block 6. Then pull the filter cotton 4, so that the filter cotton 4 can be removed from the docking ring 3 for replacement. Then put the new filter cotton 4 into the docking slot 8, and flip the limiting ring 7 in the opposite direction, so that the flipped limiting ring 7 can drive the connecting rod 9, the anti-disengagement block 10, the movable plate 11, the torsion spring 16 and the movable block 6 to flip in the opposite direction. When the flipped limiting ring 7 contacts the docking ring 3 and the filter cotton 4, pull the fixed block 15, so that the moving fixed block 15 drives the T-shaped block 14 to move and at the same time makes the spring 17 in a taut state. When the moving fixed block 15 does not affect the rotation of the movable plate 11, rotate the movable plate 11 in the opposite direction, so that the rotating movable plate 11 can drive the fixed slot 20 to rotate and at the same time make the torsion spring 16 flip and stretch, so that the torsion spring 16 is in a state of flipping and stretching. When the rotating movable plate 11 enters the positioning slot 19 and contacts the docking ring 3, the fixed block 15 corresponds to the fixed slot 20. Then release the pulled fixed block 15, so that the spring 17 is no longer restricted by the pulling force and rebounds. The rebounding spring 17 can drive the T-shaped block 14 and the fixed block 15 to move back to their original positions. When the moving fixed block 15 enters the fixed slot 20, the fixing of the torsion spring 16 is completed, so that the torsion spring 16 can no longer flip and rebound. At the same time, the fixing of the movable plate 11 and the fixed slot 20 is realized, thus realizing the fixing of the limiting ring 7, so that the limiting ring 7 can always contact the filter cotton 4.Furthermore, the filter cotton 4 can be stably located on one side of the heat dissipation port 2 to perform the work of preventing dust.
