[0023] The present invention provides a light leakage prevention structure and a novel phototherapy acne removal device, wherein the phototherapy acne removal device comprises a housing 3, a bottom cover 2, a button 1, a control unit 42, a battery 41, a wireless receiving unit 43 and a light emitting unit, Figure 1 , Figure 2 , Figure 3 as well as Figure 4 The bottom cover 2 and the button 1 are respectively snapped onto the two sides of the shell 3 to form a cavity in the shell 3 for accommodating the control unit 42, the battery 41, the wireless receiving unit 43, and the light-emitting unit. The light-emitting unit forms a light output end on one side of the acne patch, and the light output end is used to contact with the target surface.

[0024] The shell 3 is a short cylindrical structure. The cavity is axially penetrated in the shell 3 and has openings at both ends of the shell 3. The bottom cover 2 and the button 1 are respectively arranged at the openings at both ends and are snap-fitted with the shell 3 to seal both ends of the shell 3.

[0025] A plurality of first claws 21 are provided on the bottom cover 2 along the axial extension, and the first claws 21 are distributed in an array along the circumferential direction of the bottom cover 2. A plurality of first grooves for respectively engaging with the plurality of first claws 21 are provided on the inner circumferential wall of the outer shell 3. The first claw 21 moves along the axial direction of the outer shell 3 and forms an engaging engagement with the first groove, or the end of the first claw 21 is bent and extended along the circumferential direction. The bottom cover 2 and the first claw 21 are moved axially into the outer shell 3 and then rotated at a set angle, so that the end of the first claw 21 forms an engaging engagement with the first groove, thereby improving the axial connection strength between the bottom cover 2 and the outer shell 3.

[0026] A plurality of second claws 11 are provided on the key 1 along the axial extension, and the second claws 11 are distributed in an array along the circumferential direction of the key 1. A plurality of second slots for respectively engaging with the plurality of second claws 11 are provided on the inner circumferential wall of the shell 3. The second claws 11 move along the axial direction of the shell 3 and are inserted into the second slots. A hook is provided at the end of the second claw 11. The hook is slightly deformed when passing through the second slot, and axially abuts against the inner side of the second slot after the hook is completely passed through, thereby preventing the key 1 from being separated from the shell 3.

[0027] The battery 41 is installed axially into the housing 3. The inner wall of the housing 3 is provided with a limiting groove for cooperating with the outer periphery of the battery 41, so that the battery 41 is stably arranged in the housing 3 to reduce rotational displacement.

[0028] The control unit 42 and the wireless receiving unit 43 are respectively arranged on both sides of the battery 41 in the axial direction of the housing 3, and are respectively connected to the two poles of the battery 41, and the control unit 42 and the wireless receiving unit 43 are connected via FPC.

[0029] A buffer silicone sheet is also provided between the control unit 42 and the battery 41 . The buffer silicone sheet has a set thickness and a certain elastic deformation ability so as to adjust the installation dimension tolerance between the battery 41 and the outer shell 3 when the battery 41 is installed into the outer shell 3 .

[0030] The control unit 42 is provided with contacts. After the button 1 is installed on the housing 3, the contacts can be triggered when the button 1 is pressed to control the switching of the working mode of the phototherapy acne removal device.

[0031] One side of the wireless receiving unit 43 is connected to the battery 41, and the other side is connected to the light-emitting unit. The light-emitting unit includes a lamp bead 431 and a light-transmitting member 5. The lamp bead 431 is arranged in the middle of the wireless receiving unit 43. One side of the light-transmitting member 5 is against the surface of the wireless receiving unit 43 and is covered on the outer periphery of the lamp bead 431. The light-transmitting member 5 is made of transparent materials including but not limited to PC, ABS, PMMA, glass, etc. The light generated by the lamp bead 431 is emitted outward after passing through the light-transmitting member 5.

[0032] A mounting hole 22 for mounting the light-transmitting member 5 is provided through the middle of the bottom cover 2 , and one end of the light-transmitting member 5 is passed through the mounting hole 22 to form a light output end of the phototherapy acne removal device.

[0033] The light-transmitting member 5 is in a circular structure and is provided with a circular groove 51 . When the light-transmitting member 5 is covered on the lamp bead 431 , the lamp bead 431 is located in the circular groove 51 , and the light of the lamp bead 431 is irradiated on the inner wall of the circular groove 51 and refracted outwards through the light-transmitting member 5 .

[0034] When the lamp bead 431 emits light, the beam angle is close to 180°, among which the light refracted outward through the bottom surface of the circular groove 51 is effective light, which can be irradiated to the target surface through the light output end with low loss, while the light emitted by the lamp bead 431 at radial and close to radial angles will first irradiate the inner circumference of the circular groove 51. These light rays will be reflected or refracted multiple times in the light-transmitting component 5, causing greater losses.

[0035] Therefore, in some embodiments, in order to improve the utilization rate of light, refer to Figure 5 and Figure 6The light leakage prevention structure includes a focusing ring 52 protruding from the bottom of the circular groove 51, the focusing ring 52 is a circular ring structure, the inner circumference of the focusing ring 52 is formed as an empty groove for accommodating the lamp bead 431, and there is a set radial gap between the outer circumference of the focusing ring 52 and the inner circumference of the circular groove 51, wherein the inner circumferential wall of the focusing ring 52 (that is, the inner circumferential wall of the empty groove) is set as a cylindrical surface, and the outer circumferential wall of the focusing ring 52 is set as a conical surface, and the convergence direction of the conical surface is toward the side of the lamp bead 431.

[0036] The outer conical surface of the focusing ring 52 is formed as a reflective surface. The light refracted into the light-transmitting member 5 through the inner wall of the focusing ring 52 will encounter the conical surface, thereby generating reflection and reflecting the light to the light output end.

[0037] Preferably, the light-transmitting component 5 is made of PC material with a refractive index of 1.59, and the calculated total reflection angle is 39°. Therefore, the inclination angle of the reflection surface is preferably set to 40°, thereby ensuring that the light refracted by the inner wall of the focusing ring 52 toward the inside of the light-transmitting component 5 will be directed onto the reflection surface as much as possible.

[0038] Furthermore, the bottom surface of the circular groove 51 or the bottom surface of the empty groove is protruded to form a spherical surface 53 of a set size, so as to refract the light irradiated on the bottom surface toward the center of the light output end, making the light output from the light output end more concentrated.

[0039] The light refraction and reflection paths in the light-transmitting element 5 can be referred to Figure 6 as shown in .

[0040] Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work should fall within the scope of protection of the present invention.
