Description

[Technical field]

[0001] The present invention relates to the field of cosmetic devices, and in particular to photonic cosmetic devices. [Background technology]

[0002] A photonic beauty device that uses pulsed light, laser, or other light sources to achieve beauty functions is called a photonic beauty device. In a photonic beauty device, a light wave is generated in an internal light source module, and the light wave is emitted from a light output window of a working head, and beauty treatments such as hair removal, skin rejuvenation, blemish removal, anti-inflammation, blood vessel softening, wrinkle removal, skin redness removal, acne treatment, vascular lesion treatment, and pigmented lesion treatment are performed on the skin surface that is in contact with (or not in direct contact with) the end face of the working head. At present, some portable photonic beauty devices on the market require multiple filters or multiple accessory heads to be carried in order to obtain light waves of corresponding wavelengths, which causes problems such as inconvenience in use, carrying, and storage due to insertion or replacement during use. Summary of the Invention [Problem to be solved by the invention]

[0003] The technical problem that the present invention aims to solve is to provide a photonic beauty device that solves problems such as the inconvenience of using, carrying, and storing conventional photonic beauty devices with replaceable filters. [Means for solving the problem]

[0004] In order to solve the above technical problems, the technical solutions provided by the present invention are as follows: The photon beauty device includes a housing in which a light source module, a power supply unit, and a control circuit board are installed. The light source module and the power supply unit are electrically connected to the control circuit board. An emission optical path and a light emission port are installed in the head portion. The light wave generated by the light source module is propagated through the emission optical path and emitted from the light emission port. An optical filtering device with a switchable filter is built into the head portion of the photon beauty device. The optical filtering device includes one or more filters, or a filter film having a plurality of filter regions. Each filter or each filter region of the filter film is movable and switchable to the emission optical path to filter the emitted light in the emission optical path.

[0005] Furthermore, the plurality of filters are connected in series by a connecting member, or the plurality of filters are joined to form an interlocking filter. The interlocking filter is conveyed to the emission optical path by a transmission device or an adjustment mechanism to filter the emitted light wave in the emission optical path, or the one or more filters are movably installed on the side wall of the emission optical path respectively, and move or rotate to the emission optical path to filter the emitted light.

[0006] Furthermore, a bracket for limiting the emission optical path is installed in the head portion of the photon beauty device. A chute or a rotation mechanism is installed on the side wall of the emission optical path. The one or more filters or the filter film move into the emission optical path through the chute to filter the emitted light wave, or rotate into the emission optical path through the rotation mechanism to filter the emitted light wave in the emission optical path.

[0007] In some embodiments, the chute is installed in the bracket to accommodate the filter or the filter film. The filter or the filter film is reciprocally conveyed along the chute into the emission optical path to filter the emitted light wave.

[0008] In some embodiments, the chute is installed in the bracket along the longitudinal direction of the bracket and penetrates through both sides. The filter is housed in the chute along the longitudinal direction and reciprocates along the chute in the emission optical path.

[0009] In some embodiments, the filter is partitioned into two sub-filters. The sub-filters move or rotate to the emission optical path and are joined as a whole filter.

[0010] In some embodiments, outside the sidewall of the emission optical path, a storage cavity is formed. A penetrating chute is opened in the sidewall and communicates with the emission optical path, so that the filter or filter film reciprocates between the storage cavity and the emission optical path through the chute and is housed in the storage cavity, or closes the emission optical path or traverses the width within the emission optical path to filter the emitted light wave.

[0011] In some embodiments, the filter or filter film is an arc-shaped or planar filter. The optical filtering device manually adjusts the position of the filter or filter film with a manual paddle, a pull lever or a link, or automatically adjusts the position of the filter or filter film by transmission through the meshing of a motor and a gear, transmission by a belt, transmission by a chain or a screw.

[0012] In some embodiments, the optical filtering device is installed in the head part of a photon beauty device. The bracket is a base bracket. The light source module is fixedly attached to one side of the base bracket. The light source module includes a lamp tube and a reflecting cup. A light emission window is correspondingly installed on the base bracket. A fixed filter is installed on the light emission window to cover the outlet of the reflecting cup and seal and attach the lamp tube to the base bracket. A heat dissipation member is attached and installed on the outside of the light reflecting cup. A fan is installed in the head part of the beauty device. An air inlet or an air outlet is installed in the head part housing for air-cooling heat dissipation of the light source module.

[0013] In some embodiments, the optical filtering device is installed inside the accessory head. The accessory head is fitted into the head part of the photon beauty device to form an external attachment member. At the center of the top surface of the accessory head, a light emission window is installed as a light incident port and abutted against the light emission port installed in the head part of the photon beauty device. The fixed bracket includes a pair of parallel side walls, and the intermediate interval is formed as an emission optical path and a light emission port. The interval space between the parallel side walls and the outer case of the accessory head is formed as a storage cavity for storing the filter and for the filter to advance and retreat. Through-shoots are opened in the parallel side walls. The through-shoots penetrate through the emission optical path and the cavity of the accessory head, allowing the filter to slide into or exit from the emission optical path.

[0014] The photon beauty device of the present invention has an optical filtering device with a replaceable filter built-in or externally attached to the head part of the beauty device. The optical filtering device includes one or more filters or a filter film having one or more filter regions, making the filter replaceable and more convenient for use, carrying, and storage.

[0015] Hereinafter, the present invention will be described in more detail with reference to the drawings.

Modes for Carrying Out the Invention

[0017] Hereinafter, with reference to the drawings, some specific embodiments of the present invention will be described. Note that, as long as there is no contradiction, the respective embodiments of the present invention and the characteristic configurations according to the embodiments may be used in combination with each other.

[0018] Referring to FIGS. 1 to 48, embodiments of the present invention relate to a photon beauty device, and an optical filtering device 50 with a switchable filter is built in or externally attached. The optical filtering device 50 includes one or more filters 5, or includes a filter film 5 having one or more filter regions. Each filter or each filter region of the filter film is adjustable to the emission optical path so as to filter the emitted light wave in the emission optical path. By automatically or manually adjusting and switching the filter, the light wave generated by the light source module 30 in the beauty device is filtered to obtain the emitted light in the corresponding photon wavelength band, and the skin is treated to obtain the corresponding beauty effect.

[0019] When the optical filtering device is built in, in the photon beauty device of the present invention, the optical filtering device 50 is installed in the working head part. The optical filtering device 50 includes a plurality of filters. By installing a manual adjustment mechanism on the housing of the beauty device or installing an electric drive mechanism inside the beauty device, the position adjustment of the filter is driven, the filter behind the light emission port of the beauty device is switched, and after filtering the light wave, it is emitted from the light emission port of the working head part.

[0020] When the optical filtering device is externally attached, mainly, an accessory head is fitted to the working head part of the beauty device, a plurality of filters are built in the accessory head, a manual adjustment mechanism is installed on the accessory head housing, or an electric drive mechanism is installed inside the beauty device and connected to the filter of the accessory head, so as to adjust and switch the filter behind the light emission port of the accessory head, and after filtering the light wave, it is emitted from the light emission port of the accessory head.

[0021] The main body of the photon beauty device may be a hair remover. By installing the optical filtering device 50 in the hair removal working head part or fitting an accessory head to the hair removal working head part, the filter can be switched manually or automatically.

[0022] The photon beauty device according to the present invention includes a head part (i.e., a working head part) 1 and a main body 2. Note that the main body housing may be formed integrally with the housing of the working head part, or may be fixedly or movably connected to the housing of the working head part to constitute the housing of the photon beauty device. Inside the housing, a light source module 30, a power supply module 40, and a control circuit board 90 are installed. The power supply module 40 supplies power to the light source module 30. The control circuit board 90 controls the light source module 30 to emit light and generate light waves. As an example, the light source module 30 generates pulsed light waves. The front end of the working head part of the photon beauty device is a light outlet. In the front housing 10, which is the housing of the working head part, an air inlet 101 and an air outlet 102 are installed. The air inlet 101 and the air outlet 102 may be one or more sets of through holes in the housing, or may be gaps in the housing, and perform air-cooling heat dissipation for the light source module. The air inlet and the air outlet are installed according to the position of the light source module inside the beauty device.

[0023] In some embodiments, an optical filtering device 50 is installed inside the working head part of the photon beauty device. During operation, the light waves generated by the light source module 30 are filtered by the optical filtering device 50 and then propagated to the light outlet, and the transmitted light waves achieve a beauty or treatment effect. Among the light waves filtered by the optical filtering device 50, the effects on the skin vary depending on the photon wavelength band. For example, photons of 480 nm have a bactericidal and disinfection effect, photons of 530 nm have an effect of rejuvenating the skin and improving pigmentation, photons of 600 nm have an effect of softening blood vessels, and photons of 640 nm have a hair removal effect. Considering the comprehensive effects of photons, the wavelength band of the photons used needs to vary depending on skin problems. By installing filters with different wavelength bands, the filter selected during use can be switched.

[0024] An optical filtering device 50 is installed in the working head portion 1 of the photon beauty device. The optical filtering device 50 includes a plurality of filters 5. After the optical filtering device 50 is installed in the working head portion 1, different filters 5 can be switched manually or automatically, so there is no need to carry a plurality of accessories or a plurality of filters individually, and the structure is simple and easy to use.

[0025] Referring to FIGS. 1 to 9, in the first embodiment of the photon beauty device, a light source module 30 is installed in the working head portion, and the optical filtering device 50 is installed between the light source module 30 and the light exit port. The control circuit board 90 is electrically connected to the light source module 30 and the power supply unit 40, and controls the light source module to generate light waves. The power supply unit 40 supplies power to the light source module 30. The front end of the working head portion 1 of the photon beauty device is a light exit port, and the front end face is a working surface that can contact the skin for beauty treatment. The control circuit board 9 controls the light source module 30 to generate pulsed light, for example, IPL pulsed light, and performs skin care with the pulsed light transmitted after being filtered by the optical filtering device 50.

[0026] Specifically, the housing of the main body 2 includes a lower housing 20 and a display cover 21 engaged with the lower housing 20. A bezel housing 22 may be further installed between the lower housing 20 and the display cover 21. The control circuit board 90 and the power supply unit 40 are installed in the internal cavity after engagement. The power supply unit 40 may be a rechargeable battery, a disposable battery, a capacitor battery, an external power supply module, or other power supply modules of the prior art. The control circuit board 90 is provided with a power holder 91, for example, a DC power holder, for connecting to an external power supply or an internal power supply. The main body 2 is provided with push buttons, for example, a power key 95, a light key 94, etc. A light PCB and a push button panel 92 that are electrically connected to the control circuit board 90 are correspondingly installed in the main body 2.

[0027] At one end of the lower housing 20, a mounting plate 23 for attaching the working head unit 1 is installed. The mounting plate 23 may be a part (central opening) of the lower housing 20 and is used for connecting the light source module 30 and the control circuit board 90 in the main body 2. The mounting plate 23 of this embodiment is annular and is connected to the working head unit 1 by a fastening member. The working head unit 1 is connected to the main body 2 and is formed in an L shape as a whole. The main body 2 is a handheld part.

[0028] The working head unit housing includes a front housing 10 with a cylindrical structure, and a light source module 30, an optical filtering device 50, and a heat dissipation module are installed in the internal cavity. The heat dissipation module includes a fan 60. The air inlet 101 and the air outlet 102 may be installed on the front housing 10 corresponding to the position of the fan 60 and are mainly used for dissipating heat from the light source module 30. The fan 60 is installed between the light source module 30 and the mounting plate 23 of the main body 2. The cold air flowing in from the air inlet 102 is guided to the light source module 30 and further flows into the fan from the air inlet on one side of the fan 60. On the side surface of the fan spiral housing, a fan air outlet 64 communicating with the air outlet 102 installed on the front housing 10 by a gas path is installed. Further, a blowing outlet air guiding cover 61 is connected to the air outlet 64 of the fan spiral housing, and the hot air is guided to the air outlet 102 by the air guiding cover 6 and discharged to the outside of the main body. The air guiding cover 61 contributes to improving the heat dissipation efficiency. The shape of the rear end of the front housing 10 is adapted to the mounting plate 23. In this embodiment, the front housing 10 is cylindrical, the caliber of the front end is reduced, and the front end opening is for forming a light emitting port. An annular air supply cover 18 is further installed between the front housing 10 and the mounting plate 23. At the rear end of the front housing 10, the air supply cover 18 is attached to and engaged with the mounting plate 23 and is fastened and connected by a fastening member. Through holes 180 are installed on the circumference of the annular air supply cover 18 as air inlets. An annular lamp panel 13, a skin induction coil 12 (or sensor), and a front bezel 19' are further attached to the front end of the front housing 10. The annular lamp panel 13 and the skin induction coil 12 (or sensor) are electrically connected to the control circuit board 90.

[0029] The light source module 30 includes a lamp tube 3 and is electrically connected to a control circuit board 90. Electrode pieces 31 are installed at both ends of the lamp tube. An optical reflection cup 32 is installed outside the lamp tube 3. A base bracket 35 is installed inside the working head portion 1. The light source module 30 is attached to the base bracket 35. An optical emission window that coincides with the optical emission direction of the lamp tube 3 is installed at the front end of the base bracket 35. A reflector cover 17 (the inside thereof is an emission optical path for propagating light to the light emission port) is attached to the optical emission window. A whiteboard glass 16 is attached to the front end of the reflector cover 17. The whiteboard glass is attached to the front end face of the reflector cover 17 by a seal ring 11. An optical reflection cup air guide cover 34 is installed inside the working head portion 1. The light source module is attached to the base bracket 35 by the optical reflection cup air guide cover 34. An air guide passage communicating with the air supply port of the fan 60 is installed in the optical reflection cup air guide cover 34 to improve the heat dissipation efficiency of the optical reflection cup. The whiteboard glass 16 may be installed as a fixed filter, or transparent glass may be used. Further, the whiteboard glass 16 may be omitted.

[0030] A light source heat dissipation member 33 is installed in the light source module 30. The light source heat dissipation member 33 may be a fin radiator, a heat dissipation fin, a heat conduction plate, a heat pipe, or the like. In a specific example, a fin radiator or a heat dissipation fin is installed outside the light reflection cup 32 of the lamp tube. The heat dissipation member 33 includes a heat conduction base that is attached to the light reflection cup. The fin radiator or the heat dissipation fin is installed on the surface of the heat conduction base. The surface of the heat conduction base that is attached to the light reflection cup has a shape that matches the light reflection cup, so that the heat of the light reflection cup is quickly conducted to the heat dissipation member 33 for heat dissipation. The light source heat dissipation member 33 is installed inside the light reflection cup air guide cover 34. The air supply port 101 installed in the front housing 10 corresponds to the light source heat dissipation member 33. Cold air flows in from the air supply port 101 into the space on the surface of the light source heat dissipation member 33 in the working head part to absorb heat for heat dissipation. The hot air flows into the fan through the air guide passage of the light reflection cup air guide cover 34 from the air supply port of the fan, and is discharged by the fan from the air outlet 64 to the air outlet 102 of the front housing 10. The air supply port 101, the heat dissipation air path on the surface of the light source heat dissipation member 33, the air path of the fan 60, and the air outlet 102 are communicated by a gas path to form a heat dissipation air path of the light source module (refer to the air direction indicated by the arrows in FIGS. 2 to 3).

[0031] As an example, a semiconductor cooling piece is installed in the working head part 1. The low-temperature surface of the semiconductor cooling piece contacts the skin to achieve a cooling effect, or cools the end face of the light-emitting port that contacts the skin to achieve a cooling effect on the skin surface in contact. In an example, the semiconductor cooling piece 14 is attached outside the light-emitting port of the light source module, that is, in front of the light-emitting window at the front end of the base bracket 35, corresponding to the light-emitting window, having a light-transmitting area, and the light wave generated by the light source passes through the light-transmitting area of the semiconductor cooling piece. During operation, the front end face of the semiconductor cooling piece 14 can contact the skin. The light-transmitting area of the semiconductor cooling piece 14 corresponds to the whiteboard glass 16 or the light-emitting window at the front end of the base bracket 35, and covers the whiteboard glass 16 or the light-emitting window at the front end of the base bracket 35 to seal the light-emitting optical path.

[0032] Inside the working head part 1, a heat dissipation module of cooling fins including a fin radiator (or heat dissipation fins) 6, a heat pipe 62, and a heat conduction member 63 of the heat pipe is further installed. The cooling fin radiator 6 is attached to the other side of the fan 60 and faces the light source heat dissipation member 33. The cooling fin radiator 6 corresponds to the annular air supply cover 18. A through hole is installed as an air supply port on the circumference of the annular air supply cover 18. The cold air flows into the working head part from the through hole 180 and flows through the air passage formed between the fins of the cooling fin radiator. The hot air flows into the fan from the air supply port on the other side of the fan and is discharged by the fan to the air outlet 102 of the front housing 10. The through hole 180, the air passage of the cooling fin radiator 6, the air supply port on the other side of the fan 60, the air passage inside the fan, and the air outlet 102 are communicated by a gas passage to form a heat dissipation air passage for the cooling fins (refer to the air direction indicated by the arrows in FIGS. 2 to 3). The heat conduction member 63 is connected to the cooling fins to cool the cooling fins. Specifically, the heat conduction member 63 is attached by being bonded to the high-temperature surface of the semiconductor cooling fin and conducts heat in a timely manner. The heat conduction member 63 and the radiator 6 are connected to the heat pipe 62. In this embodiment, the fan has a double-sided air supply structure. One air supply port on one side is used for air supply of the light source heat dissipation air passage and is directed towards the light source heat dissipation member 33 / air guide cover, and the air supply port on the other side is used for air supply of the heat dissipation air passage of the cooling fin heat dissipation member and is directed towards the cooling fin radiator 6.

[0033] In other embodiments, the through hole 180 may be a ventilation port formed by a gap between the rear end surface of the front housing and the periphery of the mounting plate 23 of the main body 2. The beauty device housing may be provided with a multi-air supply port and an air outlet.

[0034] In this embodiment, the optical filtering device 50 is installed inside the working head part 1 and includes a plurality of filters 5 (3 are shown in the figure). The plurality of filters 5 are chain-connected to form an interlocking filter. When one side or one end connected by the chain is pushed, different filters are pushed into the light emission port / emission optical path of the working head part. Specifically, each filter 5 is fixed by a filter bracket 55. The filter brackets 55 are connected by a rotating shaft, a hinge, or a link.

[0035] In one embodiment, referring to FIGS. 1 to 6 and FIG. 9, the filter 5 is mounted within a filter bracket 55. Cam shafts 550 are respectively installed at both ends or both sides of the filter bracket 55. The link 54 is movably connected to the cam shafts 550 on both sides of the two filter brackets, thereby movably connecting each filter. Axial holes are correspondingly installed in the link 54. The cam shaft 550 is inserted into the axial hole and pivotally connected. In this embodiment, axial holes that are fitted into and rotatably engaged with the cam shafts 550 on one side of each filter bracket are respectively installed at both ends of each link 54. A pair of links movably connected to the cam shafts 550 on both sides of the filter bracket 55 of the filter 5 located at the end is the first link 53. The first link 53 may be longer than other links and installed in a curved rod shape as required. The ends of the two first links 53 are fixedly connected by a drive slider 52. A female screw axial hole 520 is installed in the drive slider 52. In this embodiment, the optical filter device 50 further includes a screw 51. The screw 51 is inserted into the female screw axial hole 520 of the drive slider 52 and screwed together to convert the rotational movement of the screw 51 into the linear movement of the drive slider 52. Referring to the directions shown in FIGS. 2 to 6 and FIG. 9, the screw 51 may be installed in a direction parallel to the axis within the working head portion 1, or may be installed in a direction along the inner wall of the front housing 10 toward the light exit port. Thereby, the drive slider 52 is reciprocated in the direction of the light exit port to reciprocate the first link 53, that is, the respective layer filters 5 connected to the links 53 and 54 are reciprocated in conjunction therewith, and the link advances and retreats the corresponding filter toward the light exit port, so that the corresponding filter is advanced and retreated in the light exit port / exit optical path, and the positions of different filters 5 are switched. The base bracket is substantially L-shaped. A lamp tube 3 is attached to the front portion of the L-shaped base bracket 35, and a light exit window is installed. The drive slider 52 and the screw 51 are attached to the rear portion (the light exit direction / the direction parallel to the axis) of the L-shaped base bracket 35. A chute 350 penetrating both sides is opened in the L-shaped base bracket 35.The chute 350 is installed along the circumferential direction of the L-shaped base bracket 35, houses a plurality of interlocking filters 5, and moves the filter 5 into the chute. The cam shafts 550 on both sides of the filter bracket 55 are respectively located in the openings on both sides of the chute 350 and protrude to the outside. Each pair of links 53, 54 is pivotally connected to the corresponding cam shaft 550 and is respectively located outside the openings on both sides of the chute 350. Preferably, the cross-section of the chute is also L-shaped. The chute 350 is installed inside the base bracket 35 and serves as the movement locus and storage space for a plurality of connected filters, eliminating the need to separately install a space or carry the filter 5 separately.

[0036] The drive slider 52 is slidably installed at the rear part (in the direction parallel to the outgoing light direction / axis) of the L-shaped base bracket 35. The drive slider 52 is a cross bar, and a pair of cam shafts are installed on both sides thereof. The cam shaft is pivotally connected to the shaft hole at the end of the first link. By matching the length of the drive slider 52 with the width of the rear part of the base bracket 35, the entire drive slider 52 is slidably fitted in the width direction of the rear part of the L-shaped base bracket 35, and the cam shafts at both ends of the drive slider 52 protrude to the outside and are connected to the shaft holes at the ends of the first link. In this embodiment, the drive slider 52 forms an interlocking structure with the links 53, 54, reciprocally slides toward the light exit port / outgoing light path, and is reciprocally slidable along the rear part of the L-shaped base bracket 35.

[0037] The rear part of the L-shaped base bracket has a cut-out structure, with the middle removed to form a cut-out space 351. Shaft holes 352 are installed on the corresponding front and rear walls of the cut-out space 351. The drive slider 52 is provided with a female screw shaft hole 520 that protrudes internally and is located within the cut-out space 351. The screw 51 penetrates through and rotatably engages with the shaft hole 352 installed on the corresponding front and rear walls of the cut-out space 351, and also penetrates through and is screwed into the female screw shaft hole 520 of the drive slider 52 within the cut-out space 351, reciprocating the slider 52 between the front and rear walls of the cut-out space 351. The front and rear walls of the cut-out space 351 function as the movement position regulation for the female screw shaft hole 520.

[0038] The screw 51 can be rotated manually or electrically. A gear end cap 510 is installed at the end of the screw 51. The optical filtering device 50 may further include an adjusting ring 56 for rotatably mounting the working head portion 1. In a specific example, the adjusting ring 56 is installed at the edge of the rear end ring of the front housing 10 and is rotatably adjusted. The adjusting ring 56 may be rotatably installed with a certain arc length (or angle). An internal rack meshing with the external rack of the gear end cap 510 is installed on the inner wall of the adjusting ring 56, and by rotating the adjusting ring 56, the gear end cap 510 (i.e., the screw 51) is rotationally driven. The rotatable arc length of the adjusting ring 56 and the length of the arc surface covered by the installed internal rack correspond to the circumferential arc length of the gear end cap 510. By the forward and reverse rotation of the adjusting ring 56, the gear end cap 510 (i.e., the screw 51) is driven to rotate forward and backward to convert it into the forward and backward reciprocating motion of the drive slider 52. The link reciprocates back and forth by pressing each filter 5 to switch different filters 5 covering the light emitting window / exit optical path at the front end of the base bracket 35.

[0039] In other embodiments, a motor may be installed in the working head portion, a gear may be fitted on the motor output shaft, and the gear may mesh with the gear end cap 510 installed at the end of the screw 51 to electrically adjust the filter. The motor is electrically connected to the control circuit board 90.

[0040] As a replacement form, after the filter 5 is fixed by the filter bracket 55, the two filter brackets 55 are connected by a pivot or hinge to form a chain connection form. Referring to FIGS. 7 to 8, shaft holes are correspondingly installed at both ends of the filter bracket. A short shaft or short pin 57 is inserted into a pair of shaft holes of two adjacent filter brackets and pivotally attached to serially connect each filter (filter bracket) to form an interlocking filter. At both ends of the filter bracket 55 of the first filter 5, the first link 53 and the drive slider 52 push the interlocking filter against the screw 51 to move and switch the filter located in the light emission window / emission optical path.

[0041] In other embodiments, other manual mechanisms connected to the filter may be installed in the working head part. By manually adjusting the position of the movable filter, the filter of the light emission window can be selected and switched.

[0042] The arrows in FIGS. 2 and 3 indicate the wind direction or the light emission direction, and the arrows in FIGS. 4(c) and 8 indicate the light emission direction. The arrow in FIG. 9 indicates the reciprocating movement direction of the drive slider 51 and the movement trajectories of the link driven thereby and the filters connected in series. The movement trajectories may be set according to the outer shape of the actual product. FIGS. 4 to 6 are state change diagrams of the switching of the filters connected in series.

[0043] In other embodiments, the chute 350 may be formed between the base bracket 35 and the inner wall of the front housing 10 and is used as a storage space for the filter for the movement of the filter 5 and the switching of the filter located at the light emission port.

[0044] As a second embodiment of the photon beauty device, referring to FIGS. 10 to 11, FIG. 10(b) is a diagram showing a simplified internal configuration. The entire housing is substantially L-shaped. The housing of the working head portion may have a housing structure integrated with the main body housing. In this embodiment, the optical filtering device 50 includes a multilayer filter 5 installed in a drawer type (or pull-out type) with a gap and in parallel. When the corresponding filter is pushed forward into the light emitting port / emission optical path, the other filters are retracted and stored in the main body. The filter 5 is fixed by a filter bracket. In FIGS. 10 to 11, a three-layer filter 5 is shown as an example. Note that FIG. 11(a) shows that the first filter is located in the light emitting port / emission optical path and filters the emitted light of the lamp tube 3. FIG. 11(b) shows that the first filter and the second filter are located in parallel in the light emitting port / emission optical path and filter the emitted light of the lamp tube 3. FIG. 11(c) shows that the first filter and the third filter are located in parallel in the light emitting port / emission optical path and filter the emitted light of the lamp tube 3. As an example, as shown in FIG. 11(a), the emitted light after the lamp tube 3 is exposed can act directly on the skin by the first filter (filter wavelength band: 500 to 1200 nm). As shown in FIG. 11(b), after the lamp tube 3 is exposed, it passes through the first filter (filter wavelength band: 500 to 1200 nm) and then through the second filter (550 to 850 nm) and is emitted, that is, the photon wavelength band acting on the skin is 550 to 850 nm. In this embodiment, the base bracket 35 may be installed with a simple structure. The lamp tube 3, the light reflecting cup 32, and the light source heat dissipation member 33 are fixedly attached. The front end face is formed as a light emitting window, and shoots 350 penetrating the side walls are installed on both opposite side walls of the emission optical path. There may be a plurality of shoots 350, and the number is the same as that of the filters (fixed by the filter brackets), and the shapes are matched. The plurality of shoots 350 are installed in parallel to pull out each filter and move it forward and backward in the light emitting port / emission optical path. The first filter may be a light emitting window sealing lamp tube 3 fixedly installed on the lamp tube.In the multi-filter of this embodiment, a manual toggle mechanism connected to each filter is installed in the beauty device housing, or the filter bracket protrudes outside the beauty device housing along the edge, and correspondingly, a movable guide rail or an opening groove is installed, so that different filters can be easily switched into the light emitting port / light emitting optical path by manual operation. Further, inside the beauty device, an electric push rod or other electric push-pull mechanism of the prior art is installed and electrically connected to the control circuit board 90 to automatically control the filter that needs to be pushed or pulled out and perform automatic adjustment.

[0045] Figures 12 to 20 show an optical filtering device according to a third embodiment of a beauty device. The plurality of filters 5 are formed by connecting arcs or are formed of the same arc-shaped base material, and the whole is arc-shaped. Referring to FIG. 20, the arc-shaped filter may be formed by joining three filters, or in the same base material, different filter regions corresponding to a plurality of filters may be formed by a process of plating while dividing regions. The arc-shaped filter of this embodiment has a smaller structural space and is applicable to all beauty device forms. In this embodiment, a fixed filter 5' and a movable and adjustable arc-shaped filter may be installed in front of the lamp tube. Referring to FIGS. 12(b), 13(b), and 14(b), the fixed filter 5' may be a planar filter, and is fixed to the light-emitting window at the front end of the base bracket 35, seals the outlet of the light reflection cup, and seals the lamp tube 3 in the light reflection cup. The light wave emitted from the lamp tube 3 is filtered by the arc-shaped filter 5 after passing through the fixed filter 5'. In other embodiments, the fixed filter 5' may not be installed (refer to FIGS. 12(a), 13(a), and 14(a)). In this embodiment, the chute 350 used for moving and switching the filter is installed on both opposite side walls of the emission optical path at the front end of the base bracket 35, and is an arc-shaped groove that engages with the arc-shaped filter 5. The movement of the arc-shaped filter 5 may be realized manually or automatically. In one embodiment, a rack is installed on the arc-shaped filter bracket 55 to which the arc-shaped filter 5 is fixed. A gear driven by a motor may be installed in the main body or the working head portion. The gear meshes with the rack of the filter bracket to rotationally drive the filter bracket 55, thereby moving the arc-shaped filter 5 and rotating the corresponding filter region or filter into the emission optical path for filtering. Similarly, a manual toggle member connected to the filter bracket 55 may be installed, or the outer edge of the filter bracket 44 may protrude directly from the beauty device housing and engage with a guide rail or guide groove, and the filter bracket 55 may be manually moved to move and switch different filters.

[0046] In other embodiments, a two - layer or multi - layer chute 350 may be installed. Referring to FIGS. 18 - 19, taking the configuration of the two - layer chute 350 as an example, by being installed in the same way as a single arc - shaped filter 5 (single - layer chute 350), it is possible to realize the switching of multi - layer filters.

[0047] Note that the arc - shaped filter 5 may be installed upward or downward. Referring to FIGS. 15 - 16, it is the same as or similar to other structures.

[0048] Referring to FIGS. 21 - 23, in the optical filtering device 50 according to the fourth embodiment of the photon beauty device, a plurality of filters 5 are in a soft connection form and can be applied to a space with a smaller angle. FIG. 22 shows a beauty device with a simplified internal structure. In this embodiment, each filter 5 may be partitioned into two half - sub - filters 5A and 5B. The sub - filter 5A is softly connected to the sub - filter 5B and jointly sent into the light exit port to perform filtering as one filter. In this embodiment, a lamp tube 3 is attached to the front end of the base bracket 35 to limit the emission optical path / light exit port (indicated by the arrow). The heat - conducting base on one side of the heat - dissipating member 33 has a surface that coincides with the outer shape of the light - reflecting cup 32, and they are attached to each other by being pasted together. Heat - dissipating fins or heat - dissipating pieces are formed on the other side. The front end of the base bracket 35 includes a two - layer wall. The interval between the two - layer walls is formed as a chute 350 used for the movement of the filter 5. The cross - section of the two - layer wall is C - shaped or similar to a C - shape, and the light - source module 30 is attached inside it. A fixed filter 5' is installed as the first filter in the light exit window, softly connecting the second filter and the third filter and accommodating them in the chute 350, and moving along the chute. FIGS. 23(a), 23(b), and 23(c) show the switching states of the filter 5, filtering the light waves emitted from the lamp tube 3 by the first filter, the first filter + the second filter, and the first filter + the third filter respectively.

[0049] The soft connection in this embodiment means dividing one filter 5 into two half-sub-filters and joining the half-sub-filters, and / or fixing or surrounding the filter 5 with a soft filter bracket 55 made of flexible plastic or an elastic material, and each adjacent filter bracket 55 is connected by an integral connection part. Also, by connecting adjacent filter brackets 55 with a connection member made of a soft or flexible material, a plurality of filters 5 are formed, or two parts of a single filter are softly connected. In the optical filtering device 50 in this embodiment, the movement and transfer of the filter are realized by using the manual or automatic adjustment method mentioned in the above-described embodiment.

[0050] In the fifth embodiment of the photon beauty device shown in FIGS. 24 to 26, the optical filtering device 50 is designed as a filter soft film, with a small occupied space and applicable to various forms of outer cases. The optical filtering device 50 is a roll filter film. The filter film includes a plurality of filter regions along the conveying direction, and a plurality of filters 5 are correspondingly formed. A pair of rollers 58 wind around both ends of the filter film respectively, and by rotating the rollers 58, the corresponding filter regions are transmitted to the light emitting port. In this embodiment, on the base bracket 35, rotating shaft bases located on both sides of the light emitting port are installed, and the pair of rollers 58 are rotatably attached. The front end of the base bracket 35 limits the emission optical path and the light emitting port / emission optical path (indicated by the arrow in FIG. 25). Shoots 350 are installed on two opposing side walls of the emission optical path or the light emitting port. Both ends of the filter film are wound around the rollers 58 respectively, and are stretched across the light emitting port by the shoots 350 and installed. The pair of rollers 58 are rotatably attached outside both side walls of the light emitting port respectively, and are installed parallel to the shoots 350. As shown in FIG. 25, a fixed filter 5' is installed as the first filter at the light emitting port (or the light emitting window at the front end of the base bracket), covering the light emitting port (light emitting window). The filter film 5 is installed in the emission optical path and is located outside the fixed filter 5'. The pulsed light emitted from the lamp tube 3 is filtered by the fixed filter 5' and the corresponding filter region of the filter film (as the second filter), and then emitted from the light emitting port. Referring to FIG. 26, FIGS. 26(a), 26(b), and 26(c) show the switching states of the positions of the filters 5, and the arrows represent the emission directions of the light rays emitted from the light source. The filter film is located at the light emitting port.

[0051] Referring to FIGS. 27 to 30, in the sixth embodiment of the photon beauty device, this filter is set in the length direction of the working head portion. When the space size at the front end 103 of the product is small but the space at the rear end 104 is sufficient (or when the space at one end / one side is insufficient and the space at the other end / one side is sufficient), it is more adaptable. A plurality of filters 5 are drawn (translated in parallel) and advanced and retreated into the emission optical path (light emission port). After the filter 5 exits from the emission optical path (light emission port), it is stored in the working head portion housing. For example, in this embodiment, it is stored at the rear end of the working head portion. Shoots 350 are installed on both of the two opposing side walls of the emission optical path at the front end of the base bracket 35. The filter 5 is supported slidably in parallel within a pair of shoots and is pushed at the front end to enter the emission optical path. A plurality of filters 5 are installed in parallel and are supported slidably by the shoots 350 installed on the side walls of the emission optical path. As shown in FIGS. 27 and 29, a fixed filter 5' is installed as the first filter within the light emission port / emission optical path to cover the opening side of the light emission window or the light reflection cup. A plurality of filters 5 are installed within the emission optical path and are located outside the fixed filter 5'. The pulsed light emitted from the lamp tube 3 is filtered by the fixed filter 5' and the plurality of filters 5 and then emitted from the light emission port. Referring to FIG. 29, FIGS. 29(a), 29(b), and 29(c) represent the switching states of the positions of the filter 5. In FIG. 29(a), the fixed filter 5' is installed at the light emission port, and the second filter and the third filter exit from the light emission port and are stored within the rear end 104 of the working head portion. FIGS. 29(b) and 29(c) respectively show that the second filter or the third filter is guided by the shoot 350 and slides into the light emission port / emission optical path and is installed in parallel with a gap from the fixed filter 5'. The pulsed light emitted from the lamp tube 3 is filtered by the fixed filter 5' and the second filter or the third filter 5 and then emitted from the light emission port and can act directly on the skin. The arrows in the figure represent the emission optical path / light emission port. The plurality of filters 5 can be switched manually or electrically and may also be realized by referring to the methods of the above-described embodiments.

[0052] Referring to Fig. 30, in the seventh embodiment of the photon beauty device, in a form where filters are inserted and joined on both sides, the requirement for space on one side is small, so it can be applied to more small-sized products. Specifically, shoots 350 are installed on both of the two opposing sidewalls of the emission optical path at the front end of the base bracket 35. The two half-sub-filters 5A and 5B of the filter 5 are slidably supported within a pair of shoots, pushed inward, move parallelly, enter the emission optical path, and are joined as a whole filter. A plurality of filters 5 are installed in parallel and are slidably supported by the multi-layer shoots 350 installed on the sidewalls of the emission optical path. A fixed filter 5' is installed as the first filter on the light emission window, covering the opening side of the light reflection cup to seal the lamp tube 3. A plurality of filters 5 are installed within the emission optical path and are located outside the fixed filter 5'. The pulsed light emitted from the lamp tube 3 is filtered by the fixed filter 5' and the plurality of filters 5 and then emitted from the light emission port. Figs. 30(a), 30(b), and 30(c) show the switching states of the positions of the filter 5. Fig. 30(a) shows that the fixed filter 5' is installed on the light emission window, and each half 5A, 5B of the second filter and the third filter exit from the emission optical path toward both sides. Figs. 30(b) and 30(c) respectively show that the two halves of the second filter or the third filter are guided and slid by the shoots 350, enter the emission optical path, are joined, and are installed in parallel at a distance from the fixed filter 5'. The pulsed light emitted from the lamp tube 3 is filtered by the fixed filter 5' and the second filter or the third filter 5 and then emitted from the light emission port, and can act directly on the skin. The arrows in the figure represent the emission optical path / light emission port. A plurality of filters 5 can be switched manually or electrically, and may also be realized by referring to the methods of the above-described embodiments.

[0053] Referring to FIGS. 31 to 36, in the eighth embodiment of the photon beauty device, the filter 5 is rotationally joined obliquely and is applicable when the working head portion 1 is a circular head and there is relatively sufficient space. In this embodiment, the main body 2 of the beauty device is a handheld portion and is an oval cylindrical body. The working head portion 1 is spherical, the front housing 10 is a spherical housing, an air inlet 101 and an air outlet 102 are installed in the housing, and an opening is provided as a light emission port. The base bracket 35 is installed in the front housing 10, a light source module is attached to its front end, includes a circular bottom plate 353, and a lamp tube 3 is attached to one side of the bottom plate 353. The lamp tube 3 is covered by a light reflection cup 32 and attached to the bottom plate 353 of the base bracket 35. Outside the light reflection cup 32, a heat dissipation member 33 is attached. The heat conduction base on one side of the heat dissipation member 33 has the same surface as the outer shape of the light reflection cup 32, is attached to each other, and the other side is formed as a heat dissipation fin or a heat dissipation piece to conduct the heat of the lamp tube to the heat dissipation member for heat dissipation. The center of the base bracket bottom plate 353 is formed as a light emission window 36, and a fixed filter 5' (referred to as the first filter) is attached. The fixed filter 5' covers the opening side of the light reflection cup 32 of the lamp tube to seal the lamp tube 3 in the light reflection cup 32. A pair of side walls are formed at the opening of the base bracket 35 from the light emission window 36 to the front housing 10 to partition and form an emission optical path (light emission port). A plurality of filters 5 of the optical filtering device are movably attached to the other side surface of the base bracket bottom plate 353. Specifically, on the bottom plate 353, two pairs (not limited to two pairs) of shoots 350 are formed in the radial direction from the central light emission window 36 as guide rails. Preferably, each pair of shoots 350 is located in a straight line, and the two pairs of shoots correspond to two straight lines and the intersection point is located at the center of the bottom plate. Two filters 5 are slidably attached in the two pairs of shoots 350. Each filter 5 is partitioned into sub-filters 5A and 5B by half, and is slidably installed on a pair of shoots respectively, pushed toward the center and joined as a whole filter 5, and located at the light emission window 36. In this embodiment, the two filters 5 attached to the other side of the bottom plate 353 are respectively used as the second filter and the third filter.When one of the sub-filters 5A and 5B moves closer in the corresponding chute 350, the other filter 5A and 5B moves away. The filter 5 may be square, and correspondingly the sub-filters 5A and 5B are triangular, and the joining line is located on the diagonal of the square. A fixing bracket 59 is installed at the edge of the sub-filter 5A or 5B. A protrusion 590 is installed on the bracket 59. The protrusion 590 is locked in the chute 350 and is slidable so as not to disengage from the chute. A locking portion is correspondingly installed on the chute 350 and the protrusion 590 to prevent disengagement. The fixing bracket 59 may be installed in an L shape and is fixed to the apex angle of the sub-filter 5A or 5B to slidably drive the sub-filter.

[0054] An annular (or arc-shaped) groove 19 is correspondingly installed on the inner wall of the front housing 10. The periphery of the base bracket bottom plate 353 is fitted into the annular groove 19. The annular groove 19 supports the edge of the base bracket bottom plate 353 but is not fixed to each other. A pair of convex teeth 190 are installed at the edge of the annular (or arc-shaped) groove 19. The pair of convex teeth 190 may be located in a straight line, protrude and extend toward the center of the bottom plate in an opposing manner, and can be movably engaged with the fixing brackets 59 of the pair of sub-filters 5A and 5B. In this embodiment, the straight lines where the two pairs of shoots 350 and the pair of convex teeth 190 are located are both the diameters of the circular bottom plate 353. In one embodiment, the front housing 10 is partitioned into two upper and lower hemispherical shapes and is engaged so as to be relatively rotatable at a certain radian (or angle). An annular (or arc-shaped) groove 19 is installed on the inner wall of the lower hemispherical housing. When the lower hemispherical housing rotates, it rotationally drives the pair of convex teeth 190. When the convex teeth 190 rotate to the shoot positions of the pair of sub-filters 5A and 5B, they movably abut against the fixing brackets 59 of the pair of sub-filters 5A and 5B and press and bring them closer until the pair of sub-filters 5A and 5B are joined. At the same time, the pair of sub-filters 5A and 5B push the other pair of sub-filters 5A and 5B away and slide them to the edge of the bottom plate. When the lower hemispherical housing reverses, the convex teeth 190 rotate and press and bring them closer until they join the other pair of sub-filters 5A and 5B. By setting the length of the convex teeth 190, the joining of the sub-filters 5A and 5B is promoted. By setting the forward and reverse rotation radians (or angles) of the lower hemispherical housing, the joining of the sub-filters 5A and 5B is promoted. In other embodiments, an adjustment ring 56 may be installed. An adjustment ring 56 is installed between the upper and lower housings of the front housing 10 so as to be rotatable at a certain radian (or angle). The annular (or arc-shaped) groove 19 and the pair of convex teeth 190 are installed on the adjustment ring 56. The edge of the bottom plate 353 is fitted into the annular (or arc-shaped) groove 19. The convex teeth 190 movably press and bring them closer until the pair of sub-filters 5A and 5B are joined.

[0055] The pulsed light generated by the lamp tube 3 is emitted from the fixed filter 5' of the light exit window 36, and the emitted light after being filtered by the second filter and the third filter 5 in the emission optical path can directly act on the skin.

[0056] Referring to FIG. 37, in the ninth embodiment of the photon beauty device, with the inner inversion type filter design, the space is small and it is applicable to all forms of beauty devices, that is, it is applicable to various shapes and space designs of beauty devices. The base bracket 35 is installed in the front housing 10 of the working head portion 1. A light source module is attached to the front end of the base bracket 35. The lamp tube 3 is covered by the light reflection cup 32 and attached to the bottom plate 353 of the base bracket 35. A heat dissipation member 33 is adhesively installed on the outer surface of the light reflection cup 32. The heat conduction base on one side of the heat dissipation member 33 has a surface with the same outer shape as the light reflection cup 32, and they are attached to each other by being bonded together, and the other side is formed as heat dissipation fins or heat dissipation pieces. The front end of the base bracket is formed as a light exit window, and a fixed filter 5' (referred to as the first filter) is attached. The fixed filter 5' covers the opening side of the light reflection cup 32 of the lamp tube and seals the lamp tube 3 inside the light reflection cup 32. As shown by the arrow in FIG. 37(a), a pair of side walls 355 are formed at the opening of the base bracket 35 from the light exit window to the front housing 10, and the space between them forms an emission optical path (light exit port). A rotation center 6 formed by a pivot or a hinge connection structure is installed on the inner wall of the side wall 355, and one filter 5 is attached as the second filter and the third filter respectively. The two filters 5 can be inverted within the emission optical path around the rotation center 6. For example, they can be inverted and switched between a vertical position and a horizontal position, rotate into the emission optical path to seal the light exit port perpendicular to the emission light direction, and become parallel to the fixed filter 5'. FIG. 37(a) shows that the two filters (the second filter and the third filter) are located in the storage portion, that is, close to the inner wall of the vertical side wall 355. FIGS. 37(b) and 37(c) respectively represent that the second filter and the third filter rotate to the horizontal position to seal the light exit port. The pulsed light emitted from the lamp tube 3 is filtered by the second filter or the third filter after passing through the fixed filter 5', and the emitted light can act directly on the skin. It should be noted that only one filter 5 may be installed, or a multilayer filter may be installed reversibly on the inner wall of the emission optical path, and one or two opposing filters 5 may be installed on each layer of the filter.In the form of the photon beauty device according to this embodiment, a beauty device or hair removal device of the prior art may be adopted such that the optical filtering device is installed in the outgoing light path outside the lamp tube, or the beauty device form (outer shape and internal configuration) according to each of the above-described embodiments may be adopted.

[0057] In addition, the rotation center 6 of this embodiment is installed at the top or bottom, that is, the filter can be installed by being bounced up or down. The filter is fixed by a filter bracket. The rotation center 6 is installed on the filter bracket or engaged with the filter bracket.

[0058] In the photon beauty device of each of the above embodiments, a reflector cover and / or a semiconductor cooling piece are installed at the light exit port, and by protruding from the opening of the front housing, the light exit port (outgoing light path) protrudes to the outside by a certain length, and the front end face can contact the skin. As the semiconductor cooling piece, the transparent crystal low-temperature surface may be used as the working surface that directly contacts the skin. In addition, outside the semiconductor cooling piece, one transparent crystal that performs cooling with the low-temperature surface of the semiconductor cooling piece may be attached and installed as the working end face, or an annular heat conduction piece may be installed as the working surface that contacts the skin.

[0059] Figs. 38 to 47 show other embodiments of the multifilter photon beauty device, that is, an externally attached form of the filter. Specifically, an accessory head 5000 is fitted to the working head portion of the beauty device. The embodiments of the built-in optical filtering device 50 in each of the above examples are all installed in the accessory head 5000 and are in a form that is fitted to the working head portion of the photon beauty device. An optical emission window 5100 is installed in the accessory head as a light incident port of the accessory head. A fixed filter 5' may be installed on the optical emission window 5100. The optical emission window 5100 of the accessory head corresponds to the optical emission port of the working head portion 1 of the beauty device body. When the accessory head is fitted to the working head portion, the optical emission window 5100 of the accessory head is aligned and connected to the optical emission port of the working head portion 1. By operating the accessory head, the filter in the accessory head can be selected and switched to the optical emission port, and the pulsed light generated by the light source of the working head portion of the beauty device is filtered by the filter of the accessory head and then emitted, and can be directly used for skin treatment. The arrows in Figs. 38 to 47 indicate the light incident port and the optical emission port of the accessory head. The fact that the accessory head is externally connected to the working head portion of the beauty device corresponds to filtering the emitted light of the light source by storing one (a fixed filter may be installed in the working head portion) or a plurality of filters in a removable extension member or an externally attached member inside the working head portion. According to such a form, one or more filters are attached to only one accessory head and are manually or automatically switched, achieving the effects of easy storage, convenient cleaning, low cost, and environmental protection.

[0060] A manual toggle member connected to the filter module of the above-described embodiment may be installed on the accessory head 5000, or by protruding the edge of the filter bracket outside the housing, it is made easy to manually adjust the position of the filter in the accessory head. The electric adjustment mechanism of the above-described embodiment may be installed on the accessory head. A sub-circuit board and / or a connector are installed on the accessory head. A connector is correspondingly installed on the beauty device main body. When the accessory head is fitted into the working head portion, the internal circuit of the accessory head is electrically connected to the internal circuit / control circuit board 90 of the main body to electrically adjust the position of the filter.

[0061] FIG. 38 is a diagram showing the structure of the accessory head 5000. In the accessory head 5000, a light emission window 5100 is installed as a light incident port at the center position of the top surface, and a pair of parallel side walls 5200 are installed inside, and an intermediate interval is formed as an emission optical path, that is, a light emission port. The interval space between the pair of parallel side walls 5200 and the outer case of the accessory head 5000 is formed as a cavity 5500 used for storing the filter 5 and advancing and retreating the filter 5. A through chute 5300 is opened in the parallel side wall 5200 to penetrate the emission optical path into the cavity 5500, so that the filter 5 can slide and advance and retreat in the emission optical path.

[0062] In the embodiment of the accessory head shown in FIG. 39, the filter 5 is arc-shaped. One basic filter (first filter) 5' is fixed at the light exit window, and one arc-shaped filter 5 is attached as the second and third filters on the left and right of the exit optical path respectively. The arc-shaped filter 5 moves from the chute 5200 into the exit optical path or the storage cavity 5300, moves into the exit optical path and closes the exit optical path laterally, filters the incident light, and then exits from the light exit port. FIGS. 39(a) to 39(c) show the switching states of the filters. Note that FIG. 39(a) shows that only the fixed filter 5' filters the incident light, and the second and third filters are stored in the cavities 5300 on both sides. FIG. 39(b) shows that the second filter slides into the exit optical path, and the incident light is filtered by the fixed filter 5' and the second filter 5 and then exits. FIG. 39(c) shows that the third filter slides into the exit optical path, and the incident light is filtered by the fixed filter 5' and the third filter 5 and then exits. Note that multilayer optical filtering devices may be installed on both sides of the exit optical path. For example, the multilayer filters on each side are installed in parallel, adjusted in combination, and various filters or multilayer filters are switched to enter the exit optical path for filtering. The plurality of arc-shaped filters in this embodiment are switched by rotational movement, and may be switched manually by installing a manual paddle / pull rod, a link, etc.

[0063] In the embodiment of the accessory head shown in FIGS. 40 to 41, the optical filtering device is designed on a filter soft film, has a small occupied space, and is applicable to various forms of outer cases. A filter soft film is wound around a pair of rollers 58, and a plurality of parallel filter regions are provided along the conveyance direction to form a plurality of filters 5. By rotating the rollers 58, the filter regions corresponding to the filter soft film are conveyed into the emission optical path as the second filter. The pair of rollers 58 are accommodated in the storage cavities 5300 on both sides of the emission optical path and are rotatably attached close to the side walls 5200. The filter soft film is stretched across both sides of the emission optical path from the through chute 5500 in the side wall and is conveyed left and right to convey different filter regions (filters) to the light emission port for filtering. Referring to the above-described embodiment, the rollers 58 are rotationally driven manually or electrically (motor + gear / motor and synchronization level / motor + worm, etc.) to switch the filters.

[0064] In the embodiment of the accessory head shown in FIGS. 42 to 44, in the optical filtering device, the filters 5 are inserted and joined on both sides of the outgoing optical path. Since the requirement for the space on one side is small, it can be applied to more small-sized products. One or more layers of shoots 5500 are formed on both side walls 5200 of the outgoing optical path. The one or more layer filters 5 slide from the shoots 5500 into the storage cavities 5300 on both the left and right sides and into the outgoing optical path, so as to be stored in the cavity 5300 or enter the outgoing optical path to seal the light exit port. In this embodiment, each filter 5 is partitioned into left and right sub-filters 5A and 5B, and is pushed into the outgoing optical path to be joined as a whole filter, and is positioned at the light exit port to filter the incident light. Note that FIG. 42 shows that only the fixed filter 5' filters the incident light, and the second and third filters are stored in the cavities 5300 on both sides. FIG. 43 shows that the second filter (joined by the sub-filters 5A and 5B on both sides) slides into the outgoing optical path, and the incident light is filtered by the fixed filter 5' and the second filter 5 and then emitted. FIG. 44 shows that the third filter (joined by the sub-filters 5A and 5B on both sides) slides into the outgoing optical path, and the incident light is filtered by the fixed filter 5' and the third filter 5 and then emitted.

[0065] Referring to the accessory head of the photon beauty device shown in FIGS. 45 to 47, the optical filtering device according to this embodiment is an inner inversion type filter, which has a small space and is applicable to all forms of beauty devices and accessory heads, that is, it is applicable to various shapes and space designs. On the inner walls of both side walls 5200 of the emission optical path, a rotation center 6 formed by a pivot or hinge structure is installed, and one filter 5 is respectively attached as the second filter and the third filter. The two filters 5 can be inverted within the emission optical path around the rotation center 6 respectively. For example, they can be inverted between a vertical position and a horizontal position, and rotate into the emission optical path to seal the light exit opening perpendicular to the emission light direction and become parallel to the fixed filter 5'. FIG. 45 shows that the two filters (the second filter and the third filter) are located on the inner wall of the storage part. FIGS. 46 and 47 respectively show that the second filter and the third filter rotate to the horizontal position to seal the light exit opening. The pulsed light is filtered by the second filter or the third filter after passing through the fixed filter 5', and the emitted light can act directly on the skin. It should be noted that only one filter 5 may be installed, or a multi-layer optical filtering device may be installed reversibly on the inner wall of the emission optical path, and one or two opposing filters 5 may be installed on each layer of the optical filtering device. It should be noted that the rotation center 6 of this embodiment may be installed at the top or the bottom. That is, the filter may be installed by being flipped up or down. The filter is fixed by a filter bracket, and the rotation center 6 is installed on the filter bracket or engaged with the filter bracket.

[0066] FIG. 48 shows the 10th embodiment of the photon beauty device. Compared with the photon beauty device shown in FIG. 1, no cooling function is installed in the working head part of the photon beauty device in this embodiment, that is, no cooling piece and heat dissipation structure 6 are installed, and only the fan is used for air-cooled heat dissipation.

[0067] It should be noted that each of the above-described embodiments incorporates a switchable optical filtering device and an accessory head, and is applicable to a photon beauty device with cooling or a photon beauty device that cannot be cooled.

[0068] In some embodiments, the wavelength of the light emitted from the filter 5 (the light wave filtered by the filter) may be 510 nm to 1200 nm, 530 nm to 1200 nm, 560 nm to 1200 nm, 590 nm to 1200 nm, 610 nm to 1200 nm, 640 nm to 1200 nm, or 645 to 750 nm.

[0069] In the optical filtering device 5 used in a photon beauty device having a hair removal function, it is preferable that the wavelength of the light wave of the filter is 610 nm or more. For example, an optical filtering device using a range of 610 to 1200 nm transmits light waves with wavelengths exceeding 610 nm to the working surface 10. In other embodiments, at least one optical filtering device 5 with light waves of 645 to 750 nm, that is, a two-wavelength band filter, may be used to filter light waves of 645 nm or less and 750 nm or more, and the wavelength of the emitted light is 645 to 750 nm.

[0070] Examples of the wavelength of the filter and the beauty effect of the photon beauty device include, but are not limited to, the following examples. A filter of 430 to 1200 nm: It is possible to treat inflammatory acne. A filter of 480 to 1200 nm: It is possible to treat acne and vascular lesions. A filter of 530 to 1200 nm: It is possible to treat vascular lesions (superficial thin blood vessels) and pigmentation lesions. A filter of 560 to 1200 nm: It is possible to treat wrinkle removal, pigmentation lesions, and vascular lesions (deep thick blood vessels). A filter of 640 to 1200 nm: It is possible to perform hair removal, skin rejuvenation, and remove deep redness. A filter of 690 to 1200 nm: It is possible to perform hair removal, remove deep redness, etc.
