[0058] Furthermore, in the description of the present invention, unless otherwise specified, “plurality” means two or more.

[0059] For those skilled in the art, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0060] Please follow Figure 1 and Figure 2 A photon skin rejuvenation device according to an embodiment of the present invention includes: a housing 1, a lamp 2, a light guide column 3, a filter 4 and a driving device 5.

[0061] The housing 1 has a first opening 11 communicating with the interior thereof.

[0062] The lamp 2 is arranged inside the housing 1 .

[0063] The light guide column 3 is partially disposed inside the housing 1 , and at least a portion of the light guide column 3 is exposed through the first opening 11 .

[0064] The filter element 4 is disposed inside the housing 1 and includes a plurality of filter portions 41 .

[0065] The plurality of light filters 41 may be light filters 41 of different wavelength bands, and in this embodiment, one of the light filters 41 is located between the light guide column 3 and the lamp 2 .

[0066] The driving device 5 is connected to the filter element 4 , and is used to drive the filter element 4 to move, so that different filter portions 41 can move between the light guide column 3 and the lamp 2 .

[0067] The light guide column 3 is a sapphire light guide column 3. Since the sapphire light guide column 3 has good optical properties and high light transmittance, it can allow light to pass through efficiently, reduce light energy loss, and ensure the treatment effect. At the same time, it has low light scattering, which can make the light be conducted more concentratedly, ensuring that the light energy acts evenly on the skin surface. The sapphire light guide column 3 also has excellent thermal conductivity, which can quickly conduct away the heat generated during the photorejuvenation process to avoid local heat accumulation. This helps to maintain the working stability of the photorejuvenation device, and can also protect the skin and reduce the risk of adverse reactions such as burns caused by overheating. In addition, the sapphire light guide column 3 also has the characteristics of good biocompatibility, is non-toxic and harmless to the human body, and has good biocompatibility. When the sapphire light guide column 3 is in direct contact with the skin for photorejuvenation treatment, it will not cause adverse phenomena such as immune reactions or allergies in the human body, and can provide users with a safe and comfortable treatment experience.

[0068] When using the photon therapy device, the light guide column 3 needs to be attached to the skin so that the light of the light guide column 3 can directly act on the skin.

[0069] In this embodiment, at least a portion of the light guide 3 extends out of the housing 1 through the first opening 11 .

[0070] With such a structure, the light guide column 3 can be conveniently brought into direct contact with the skin, making it easier for the user to use.

[0071] The filter portion 41 of the filter element 4 plays the role of filtering light of a specific wavelength band. It can filter out light of a desired wavelength band as needed, and can also filter out some light of a certain wavelength band that may be harmful to the human body or have no therapeutic effect, thereby reducing unnecessary stimulation and harm to the human body.

[0072] The filter section 41 is provided with multiple different wavelength bands, which can filter light of different wavelength bands to achieve different functions. For example, light of the 400nm-700nm wavelength band can be used to remove acne, and light of other wavelength bands can also be used to improve freckles, sun spots, skin redness, and enhance skin elasticity.

[0073] The driving device 5 can drive the filter 4, allowing different filter sections 41 to switch between the light guide column 3 and the lamp 2, so that light of different wavelength ranges is injected into the light guide column 3, so that the light guide column 3 can emit light of different wavelengths to achieve different functions. When the filter section 41 is switched, the filter 4 remains in the state inside the housing 1, and there is no need to remove the filter 4 from the housing 1. The filter 4 does not come into contact with the external environment, thereby keeping the filter 4 clean, protecting the filter 4, reducing contamination of the filter 4, and preventing external dust and dirt from damaging the filter 4.

[0074] In some embodiments, the filter 4 is cylindrical, and the filter 4 is mounted on the outside of the lamp 2. The multiple filter parts 41 are distributed on the circumference of the filter 4, and the different areas on the filter 4 are the filter parts 41; the driving device 5 can drive the filter 4 to rotate so that the position of the corresponding filter part 41 moves to between the light guide column 3 and the lamp 2.

[0075] The filter portion 41 currently located between the light guide 3 and the lamp 2 is referred to as a working filter portion 42 .

[0076] Each filter portion 41 extends to both ends of the central axis of the filter element 4. When the filter element 4 rotates, different filter portions 41 will be moved between the light guide column 3 and the lamp 2 according to the rotation, becoming the working filter portion 42. This allows light emitted by the lamp 2 to pass through the working filter portion 42 to filter out light of a specific wavelength band, and then enter the light guide column 3 to achieve different functions.

[0077] The two adjacent filter parts 41 may be in contact with each other or spaced apart from each other, and may be arranged according to actual needs during the actual production process or product implementation.

[0078] In this embodiment, please refer to Figure 8 The filter element 4 includes a cylinder and a filter film. The cylinder can be rotatably connected in the housing 1. Each filter film is arranged on the cylinder. The cylinder is used to support the filter film and form the corresponding filter part 41.

[0079] Specifically, a hollow portion may be provided on the cylindrical body to support the edge of the filter film, thereby forming a filter portion.

[0080] The cylinder can also be made of a light-transmitting material, and the filter films can be attached to the surface of the cylinder. The filter films can cover areas on the cylinder to form filter parts 41 of different wavelength bands.

[0081] The cylindrical body is in the shape of a cylinder with at least one opening along its own axial direction. In this embodiment, both ends of the cylindrical body are open.

[0082] In this embodiment, the light-transmitting material used to make the cylindrical body is quartz glass. Quartz glass has excellent optical stability, and its optical parameters, such as transmittance and refractive index, are not susceptible to change over long-term use. Even under prolonged exposure, it exhibits no noticeable optical degradation, maintaining excellent light transmittance and optical uniformity. Quartz glass also has a wide light transmittance range, extending from the ultraviolet to the infrared, making it an ideal substrate for filters designed for different wavelengths. The high light transmittance of quartz glass reduces light loss from the lamp 2 as it passes through the cylindrical body.

[0083] The filter films can be filter films of different wavelength bands.

[0084] The filter film is a thin film attached to the surface of the cylinder that selectively transmits or blocks light of specific wavelengths. Different filter films can selectively transmit or block light of different wavelengths. In this embodiment, the edges of adjacent filter films are aligned so that there is no gap between the filter portions 41 formed by adjacent filter films. Alternatively, the edges of adjacent filter films may overlap. In actual production or product implementation, the arrangement of the filter films can be customized according to actual needs.

[0085] Please refer to Figure 9 The shape of the light guide column 3 is adapted to the cylinder.

[0086] Please refer to Figure 4 and Figure 11 The photon rejuvenation device of this embodiment further includes a reflector 6, each of which has an opening facing the direction of the light guide column 3. The reflector 6 is arranged inside the filter 4, and the reflector 6 is used to reflect the light emitted by the lamp 2 toward the filter part 41 located between the light guide column 3 and the lamp 2.

[0087] Specifically, at least a portion of the lamp 2 is covered inside the reflector 6 , and the light guide column 3 and the reflector 6 are respectively provided on both sides of the filter portion 41 between the light guide column 3 and the lamp 2 .

[0088] The light emitted by the lamp 2 is scattered around, and the working filter part 42 is located on the side of the lamp 2 facing the light guide column 3. In order to better utilize the light emitted by the lamp 2, the reflector 6 is provided to gather the light from the lamp 2 in directions other than those toward the light guide column 3, and reflect it toward the working filter part 42, thereby improving the light utilization rate of the lamp 2.

[0089] In this embodiment, the second opening faces the filter portion 41 between the light guide column 3 and the lamp 2 .

[0090] Specifically, the cross-section of the reflector 6 is formed in a "C" shape, and the second opening faces the working filter part 42, so as to gather the light of the lamp 2 in directions other than toward the light guide column 3 and reflect it toward the working filter part 42, thereby improving the light utilization rate of the lamp 2.

[0091] In some embodiments, please refer to Figure 6 The portion of the light guide column 3 exposed through the first opening 11 has a working surface 31 , and the projection area of ​​the second opening on the working surface 31 is smaller than or equal to the area of ​​the working surface 31 .

[0092] While the light guide 3 can be shaped and sized as desired, at least a portion of the light guide 3 exposed by the first opening 11 must be in contact with the skin. The working surface 31 is the surface that contacts the skin. In this embodiment, the working surface 31 is the surface opposite the plane of the first opening 11 and is also the surface from which most of the light in the specific wavelength band passing through the working filter 42 exits the light guide 3.

[0093] The projection area of ​​the second opening on the working surface 31 is less than or equal to the area of ​​the working surface 31, so that the light reflected by the reflector 6 can be filtered by the working filter portion 42, and most of the light of the specific wavelength band can enter the light guide column 3, thereby reducing the light of the specific wavelength band from being projected onto the inner wall of the shell 1 or other components in the shell 1, thereby reducing the waste of light.

[0094] Please refer to Figure 5 In this embodiment, the projection contour of the light guide column 3 on the working filter portion 42 falls within the contour range of the working filter portion 42 .

[0095] The contour range of the working filter section 42 is larger than the projection contour of the light guide column 3, so that the light emitted to the light guide column 3 is all light of a specific wavelength band filtered by the working filter section 42, thereby reducing the presence of light of other wavelength bands that have not been filtered by the working filter section 42 in the light emitted to the light guide column 3, thereby reducing the risk of these wavelength bands of light irritating the skin and affecting the treatment effect.

[0096] In some embodiments, please refer to Figure 4 and Figure 10 The lamp 2 includes a lamp holder 21 and a lamp tube 22. The lamp holder 21 is arranged inside the housing 1. The lamp tube 22 is arranged on the lamp holder 21. At least a portion of the lamp tube 22 extends into the filter 4. The reflector 6 is arranged on the lamp holder 21.

[0097] The lamp tube 22 is fixed to the lamp holder 21 and inserted into the cylindrical body. The reflector 6 is also fixed to the lamp holder 21. With this structure, the positions of the lamp tube 22 and the reflector 6 can be fixed and kept stable in the current position.

[0098] The lamp holder 21 is arranged at one end of the opening of the cylinder, so that the lamp tube 22 can be inserted into the interior of the cylinder along the opening of the cylinder.

[0099] In this embodiment, the lamp tube 22 adopts a dual-lamp tube 22 structure to improve the output of light energy. The two light sources operate simultaneously, providing stronger light energy. Sufficient light energy can ensure the photorejuvenation effect. Therefore, this structure can shorten the treatment time: because the dual-lamp tube 22 can output higher light energy, better treatment effects can be achieved in a shorter time, which can reduce discomfort during treatment, while also improving treatment efficiency and saving time. In addition, the dual-lamp tube 22 structure can also enhance treatment uniformity: the two lamp tubes 22 can emit light from different angles or positions, making the light more evenly distributed on the skin surface after passing through the light guide column 3. This can avoid the problem of uneven lighting, reduce omissions in the treatment area or inconsistent energy, thereby ensuring that the entire treatment area receives uniform and effective treatment, and improving the consistency of treatment effects.

[0100] The reflector 6 at least covers a portion of the lamp tube 22 , and the shape of the reflector 6 is adapted to the lamp tube 22 .

[0101] In this embodiment, since the lamp tube 22 adopts the structure of the double lamp tube 22 , the reflector 6 is provided with recesses at the positions of the two lamp tubes 22 corresponding to the double lamp tube 22 to adapt to the shape of the reflector 6 .

[0102] In some embodiments, please refer to Figure 7 The driving device 5 includes a driver 51, a driving gear 52 and a transmission gear 53. The driver 51 is arranged inside the housing 1, the driving gear 52 is arranged on the driving shaft of the driver 51, and the transmission gear 53 is arranged on the filter element 4. The driving gear 52 and the transmission gear 53 are meshed with each other.

[0103] The transmission gear 53 is sleeved on the outside of the barrel and is located at the end of the barrel away from the lamp tube 22 inserted into the barrel, that is, at the end of the barrel away from the lamp holder 21. With this structure, the arrangement of the filter parts 41 is not affected, and the barrel can rotate stably.

[0104] The driving gear 52 and the transmission gear 53 are meshed with each other for transmission, and the transmission efficiency is high and the transmission ratio is stable. In particular, in this embodiment, each filter part 41 is located at a different position of the cylinder. When switching different filter parts 41, the rotation degree of the cylinder needs to be precisely controlled. The transmission method of the driving gear 52 and the transmission gear 53 can achieve precise control of the rotation degree of the cylinder.

[0105] The driver 51 is a stepper motor. This motor can precisely control the rotation angle and position, achieving high-precision positioning control. Furthermore, the stepper motor has excellent speed control characteristics, which facilitates the meshing transmission between the drive gear 52 and the transmission gear 53. Furthermore, the stepper motor has a self-locking function, preventing the working filter 42 from being unable to maintain its current position after the driver 51 stops operating. In other embodiments, other motors such as servo motors may also be used, and the configuration can be tailored to actual needs.

[0106] In this embodiment, the photon skin rejuvenation device further includes a cooling plate 7 , which is disposed on the light guide column 3 . The cooling plate 7 is in contact with the light guide column 3 and is used for exchanging heat for the light guide column 3 .

[0107] When the photon rejuvenation device is in operation, the light directed toward the light guide 3, as well as the heat radiation generated by the lamp 2, the drive device 5, and other components, can increase the temperature of the light guide 3. By providing the cooling plate 7, the light guide 3 can be cooled. The light guide 3 is in direct contact with the skin, and the temperature of the light guide 3 is reduced, which can improve the user experience. Furthermore, it can prevent the optical properties of the light guide 3 from changing due to the temperature increase, such as changes in the refractive index and a decrease in transmittance. By reducing the temperature of the light guide 3, the cooling plate 7 can reduce these adverse effects, ensure the stability of the optical properties of the light guide 3, and make the transmission efficiency of light within the light guide 3 higher and the loss lower. Furthermore, it can reduce the accelerated aging of the light guide 3 material due to the temperature increase. By cooling the light guide 3, the cooling plate 7 can keep the light guide 3 in a relatively low temperature environment, slowing down the aging of the material, extending the service life of the light guide 3, and reducing maintenance and replacement costs.

[0108] The refrigeration plate 7 is a semiconductor refrigeration plate 7, which is a device that uses the Peltier effect of semiconductor materials to achieve refrigeration. It has a relatively fast cooling speed and can meet the requirement that the refrigeration plate 7 can also effectively cool down while the light guide column 3 is working. The semiconductor refrigeration plate 7 does not need to be provided with a refrigerant, so there is no risk of refrigerant leakage. The semiconductor refrigeration plate 7 has no mechanical moving parts during operation, so it does not generate noise, providing a quiet use environment for the user and improving the user experience. The structure of the semiconductor refrigeration plate 7 is relatively simple, consisting of semiconductor materials, electrodes and other parts. It is small in size and easy to install and integrate. It is particularly suitable for occasions where space is limited. It does not occupy the internal space of the photon rejuvenation instrument, reducing the overall size of the photon rejuvenation instrument.

[0109] In this embodiment, the cooling plate 7 is attached to the light guide column 3 , and one side of the cooling plate 7 is exposed by the first opening 11 . In other embodiments, the specific position of the cooling plate 7 can also be set according to actual conditions.

[0110] The photon skin rejuvenation device of this embodiment further includes a radiator 8 , which is disposed inside the housing 1 and in contact with the cooling plate 7 . The radiator 8 is used to dissipate heat for the cooling plate 7 .

[0111] The cooling fins 7 generate a large amount of heat during operation. If this heat cannot be dissipated promptly, the temperature at the hot end of the cooling fins 7 will rise. The cooling efficiency of the cooling fins 7 is related to the temperature difference between the hot and cold ends. Excessively high hot end temperatures can reduce cooling efficiency and even damage the cooling fins 7. The provision of the heat sink 8 effectively reduces the hot end temperature of the cooling fins 7, ensuring stable performance.

[0112] The heat sink 8 contacts the cooling fins 7 and transfers heat from the cooling fins 7 to the heat sink 8. The heat sink 8 is provided with a plurality of fins, which increase the surface area for heat dissipation, thereby increasing the speed of heat dissipation. The heat generated by the cooling fins 7 is transferred to the heat sink 8 and then quickly dissipated into the surrounding air through the fins.

[0113] Please refer to Figure 3 The photon skin rejuvenation device of this embodiment further includes a fan 9, which is arranged inside the shell 1. A third opening 12 is provided on the shell 1. The shell 1 forms an air duct 13 between the air outlet of the fan 9 and the third opening 12. At least a part of the radiator 8 is located in the air duct 13.

[0114] The air blown by the fan 9 passes through the air duct 13 and then exits the housing 1 through the third opening 12. At least a portion of the radiator 8 is disposed within the air duct 13, and the air flows directly over the surface of the radiator 8. The forced airflow generated by the fan 9 accelerates the flow of air around the radiator 8, promptly removing heat absorbed by the radiator 8, thereby significantly improving heat dissipation efficiency. In this embodiment, the fins of the radiator 8 are located within the air duct 13, thereby improving the heat dissipation efficiency of the fins.

[0115] In this embodiment, the first opening 11 and the third opening 12 are on different sides of the housing 1. Since the light guide 3 of the first opening 11 directly contacts the skin, the third opening 12 needs to blow out air heated by the heat sink 8. This arrangement neither affects the air flow nor allows the hot air to directly hit the user's skin, thereby improving the user experience.

[0116] In this embodiment, the housing 1 is box-shaped, with the first opening 11 disposed on a side of the housing 1, located in the middle and forming only a portion of the side of the housing 1. The rear side of the housing 1 is open; in other words, the housing 1 lacks a back panel, and the open rear side of the housing 1 forms the third opening 12. In other embodiments, the structure of the housing 1, as well as the positions and dimensions of the first and third openings 11, 12, can be configured according to specific needs.

[0117] The photon skin rejuvenation device of this embodiment further includes a controller 14 , which is electrically connected to the lamp 2 and the driving device 5 .

[0118] The controller 14 is a PLC that can control whether the lamp 2 and the driver 5 are working and their working status. The controller 14 can be disposed inside or outside the housing 1. Specifically, the controller 14 is electrically connected to the driver 51 and the lamp 22.

[0119] In addition, the controller 14 is also electrically connected to the refrigeration fins 7 and the fan 9, and can control whether the refrigeration fins 7 and the fan 9 are working and their working status.

[0120] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and substitutions can be made without departing from the technical principles of the present invention. These improvements and substitutions should also be regarded as the scope of protection of the present invention.
