In this embodiment, the filter device 50 further includes a screw 51, which is inserted into the internal threaded shaft hole 520 of the driving slider 52, and the threads are matched, so that the rotational motion of the screw 51 is converted into the linear motion of the driving slider 52. Figure 2-6 as well as Fig. 9 As shown in the direction, the screw 51 can be arranged in the working head 1 along the direction parallel to the axis, or along the inner wall of the front shell 10 toward the light outlet, so that the driving slider 52 reciprocates in the direction of the light outlet, driving the first connecting rod 53 to reciprocate, that is, driving the layers of filters 5 connected by the connecting rods 53 and 54 to reciprocate, and the connecting rod drives the corresponding filter to advance or withdraw toward the light outlet, thereby pushing the corresponding filter to the light outlet / light outlet channel or withdrawing from the light outlet / light outlet channel to realize the position switching of different filters 5. The lamp holder bracket is roughly L-shaped, the front section of the L-shaped lamp holder bracket 35 is installed with the lamp tube 3 and the light outlet window, and the rear section (light outlet direction / axis parallel direction) of the L-shaped lamp holder bracket 35 is installed with the driving slider 52 and the screw 51; the L-shaped lamp holder bracket 35 is provided with a slide groove 350 running through both sides, and the slide groove 350 is arranged along the circumference direction of the L-shaped lamp holder bracket 35, and is used to store multiple linked filters 5 and allow the filters 5 to move in the slide groove, and the convex shafts 550 on both sides of the filter holder 55 are respectively located in the openings on both sides of the slide groove 350 and extend outward, and each pair of connecting rods 53 and 54 are rotatably connected with the corresponding convex shafts 550, and are respectively located outside the openings on both sides of the slide groove 350. Preferably, the cross section of the slide groove is also L-shaped. The slide groove 350 is arranged inside the lamp holder bracket 35, and is used as the movement track and storage space of multiple linked filters, and there is no need to set up a separate space, and there is no need to carry the filters 5 separately.

[0116] The driving slider 52 is slidably disposed on the rear section (light emitting direction / axis parallel direction) of the L-shaped lamp holder bracket 35. The driving slider 52 is a crossbar structure, and a pair of convex shafts are respectively disposed on both sides, and the convex shafts are rotatably connected to the shaft hole at the end of the first connecting rod. The length of the driving slider 52 is adapted to the width of the rear section of the lamp holder bracket 35. The entire driving slider 52 can be slidably sleeved in the width direction of the rear section of the L-shaped lamp holder bracket 35. The convex shafts at both ends of the driving slider 52 extend outward and are connected to the shaft hole at the end of the first connecting rod. In this embodiment, the driving slider 52 forms a linkage structure with the connecting rods 53 and 54, and reciprocates toward the light outlet / light outlet channel, and can reciprocate along the rear section of the L-shaped lamp holder bracket 35.

[0117] The rear section of the L-shaped lamp holder bracket is a hollow structure, and a hollow space 351 is formed in the middle. A shaft hole 352 is provided on the front and rear walls corresponding to the hollow space 351. The driving slider 52 is provided with an internal thread shaft hole 520, which is located in the hollow space 351 protruding inward. The screw 51 passes through the shaft hole 352 provided on the front and rear walls corresponding to the hollow space 351, rotates and fits, and passes through the internal thread shaft hole 520 of the driving slider 52 located in the hollow space 351 and threads, driving the slider 52 to reciprocate between the front and rear walls of the hollow space 351.

The filter device 50 may also include an adjustment ring 56, which is rotatably mounted on the working head 1. In a specific example, the adjustment ring 56 is provided at the edge of the rear end ring of the front shell 10 and can be rotatably adjusted. The adjustment ring 56 can be set to be rotatable to a certain arc length (or angle). An inner rack is provided on the inner wall of the adjustment ring 56, which meshes with the outer rack of the gear end cover 510. The adjustment ring 56 is rotated to drive the gear end cover 510 (i.e., the screw 51) to rotate. The length of the arc that the adjustment ring 56 can rotate and the length of the arc surface covered by the inner rack correspond to the circumferential arc length of the gear end cover 510. The forward and reverse adjustment ring 56 drives the gear end cover 510 (i.e., the screw 51) to rotate forward and reverse, which is converted into driving the slider 52 to move back and forth. The connecting rod pushes each filter 5 to move back and forth to switch between different filters 5 covering the light outlet window / light outlet channel at the front end of the lamp holder bracket 35.

Specifically ( Figure 49-50), when the graphene filter 5 is switched to be located at the light outlet; the positive electrode 501 and the negative electrode 502 are electrically connected to the control circuit board 90, powered by the power supply unit 40, the circuit between the graphene sheet 500 and the control circuit board in the photon beauty instrument is connected, and the graphene filter filters the light emitted by the light source assembly 30 and emits light waves in the far-infrared band at the same time.

[0120] In other embodiments, a motor may be provided in the working head and a gear may be sleeved on the motor output shaft, and the gear may be meshed with a gear end cap 510 provided at the end of the screw rod 51 to electrically adjust the filter.

[0121] As an alternative, after the filter 5 is fixed by the filter holder 55, the two filter holders 55 are connected by a pivot or hinge to form a watch band link. Figure 7-8 , shaft holes are correspondingly arranged at both ends of the filter holder, and a short shaft or short pin 57 is inserted into a pair of shaft holes of two adjacent filter holders to form a pivot connection, so that each filter (filter holder) is serially connected into a linked filter. The linked filter can be pushed by the screw 51 at both ends of the filter holder 55 of the first filter 5 through the first connecting rod 53 and the driving slider 52 to switch the filter located in the light exit window / light exit channel.

[0122] In other embodiments, other manual mechanisms may be provided on the working head to connect the optical filters, and the position of the optical filters may be manually adjusted to select and switch the optical filters of the light output window.

Fig. 9 The middle arrow indicates the reciprocating motion direction of the driving slider 51 and the moving trajectory of the connecting rod driven by it and the filter connected in series. The motion trajectory can also be set according to the actual appearance of the product. Figure 4-6 The diagram shows the state change of the serially connected filters switching.

[0124] In other embodiments, the slide groove 350 may also be formed between the lamp holder bracket 35 and the inner wall of the front shell 10 to serve as a filter accommodation space for the filter 5 to move and switch the filter located at the light outlet.

The housing of the whole machine is roughly L-shaped, and the housing of the working head and the housing of the machine body can be an integrated housing structure. In this embodiment, the filter device 50 includes multiple layers of filters 5, which are arranged in parallel and spaced apart in a pull-out (or drawer-type) manner, and the corresponding filters are pushed forward to the light outlet / light outlet channel, and other filters are withdrawn and stored in the machine body. The filter 5 is fixed by a filter holder. Figure 10-11 The three-layer filter 5 is used as an example for illustration, wherein: Fig.11 (a) indicates that the first filter is located in the light outlet / light outlet channel and is used to filter the light emitted by the lamp 3. Fig.11 (b) indicates that the first and second filters are located in parallel in the light outlet / light outlet channel for filtering the light emitted by the lamp tube 3. Fig.11 (c) indicates that the first and third filters are located in parallel in the light outlet / light outlet channel for filtering the light emitted by the lamp 3. As an example, Fig.11 (a), the photons emitted by the lamp 3 pass through the first filter (filter band 500-1200nm), and the emitted light can directly act on the skin. Fig.11(b), the photons emitted by the lamp tube 3 pass through the first filter (500-1200nm) and then pass through the second filter (550-850nm) to emit light, that is, the photon band acting on the skin is 550-850nm. In this embodiment, the lamp holder bracket 35 can be set with a simple structure, the lamp tube 3 and the reflective cup 32, the light source heat sink 33 are installed and fixed, the front end surface forms a light outlet window, and the opposite side walls of the light outlet channel are provided with a slide groove 350 that penetrates the side wall. The slide groove 350 can be multiple, the number is consistent with the number of filters (fixed by the filter bracket), and the shape is adapted. The multiple slide grooves 350 are arranged in parallel, respectively used for each filter to be pulled into or out of the light outlet / light outlet channel. The first filter can be a light outlet window sealed lamp tube 3 fixedly set on the lamp tube. The multiple filters of this embodiment can be easily switched manually by setting a manual toggle mechanism connecting each filter on the beauty instrument housing or making the filter holder extend out of the beauty instrument housing along the edge, and correspondingly setting a movable guide track or slot, so that different filters can be easily switched into / out of the light channel. Alternatively, an electric push rod or other electric push-pull mechanism of the prior art is set inside the beauty instrument, which is electrically connected to the control circuit board 90 to automatically control the filter that needs to be pushed in or pulled out for automatic adjustment. In this embodiment, one or more of the first, second, and third filters can also use the graphene filter 5 of the following embodiment, so that while obtaining photons of corresponding wavelengths for beauty treatment, the graphene sheet 500 is connected to generate far infrared, and far infrared therapy is achieved at the same time. Specifically, when the graphene filter 5 is located at the light outlet, the positive electrode 501 and the negative electrode 502 are electrically connected to the control circuit board 90, and the power is supplied by the power supply unit 40. The circuit between the graphene sheet 500 and the control circuit board 90 in the photon beauty instrument is connected, and the graphene filter 5 filters the light emitted by the light source assembly 30 and emits far-infrared light waves. It can be understood that the first filter (fixed filter) can also be white glass (transparent glass), which plays the role of sealing the lamp tube in the reflective cup and transmitting light.

[0126] Figure 12-20 The filter device used in the third embodiment of the photon beauty instrument is shown, and multiple filters 5 are connected in an arc shape or formed by the same arc-shaped substrate, and the whole is an arc shape. Fig. 20 The arc filter can be formed by splicing three filters, or it can be formed on the same substrate through a zoned coating process to form different filter areas equivalent to multiple filters. The arc filter of this embodiment has a smaller structural space and can adapt to all beauty instrument forms. In this embodiment, a fixed filter 5' and a movable and adjustable arc filter can be set in front of the lamp tube. Fig.12(b), 13(b), 14(b), the fixed filter 5' can be a flat filter, fixed to the light outlet window at the front end of the lamp holder bracket 35, sealing the outlet of the reflector cup, and sealing the lamp tube 3 therein. The light waves emitted by the lamp tube 3 pass through the fixed filter 5' and then through the curved filter 5. In other embodiments, the fixed filter 5' may not be provided, refer to Fig.12 (a), 13(a), 14(a). In the present embodiment, a slide groove 350 for moving and switching the filter is arranged on the opposite side walls of the light output channel at the front end of the lamp holder bracket 35, and the slide groove 350 is an arc-shaped groove, which is compatible with the arc-shaped filter 5. The movement of the arc-shaped filter 5 can be achieved manually or automatically. As an embodiment, a rack is provided on the arc-shaped filter holder 55 that fixes the arc-shaped filter 5, and a motor-driven gear can be provided in the fuselage or the working head. The gear is engaged with the rack of the filter holder to drive the filter holder 55 to rotate, thereby moving the arc-shaped filter 5, so that the corresponding filtering area or filter rotates to the light output channel for filtering. Similarly, a manual shifter connected to the filter holder 55 can be provided, or the outer edge of the filter holder 55 can be directly protruded and set on the beauty instrument housing, and the filter holder 55 can be manually shifted in cooperation with the guide track or guide groove, so as to move and switch different filters. Combined with Figure 49-5 0, one or more filters or one or more filter areas of the multi-sheet filter 5 of this embodiment can adopt the graphene filter 5 of the following embodiment, which can be a composite filter formed by further forming a graphene sheet 500 coating on the surface of the filter area and the base filter, so that the graphene sheet 500 circuit is connected to generate far infrared while obtaining photons of corresponding wavelengths for beauty treatment, and far infrared therapy is achieved at the same time. Specifically, when the graphene filter (or graphene filter area) 5 is located at the light outlet; the positive electrode 501 and the negative electrode 502 are electrically connected to the control circuit board 90, and the power is supplied by the power supply unit 40, the circuit between the graphene sheet 500 and the control circuit board 90 in the photon beauty instrument is connected, and the graphene filter 5 filters the light emitted by the light source assembly 30 and emits light waves in the far infrared band. It can be understood that the fixed filter can also adopt the graphene filter 5, or it can be white glass (transparent glass), which plays the role of sealing the lamp tube in the reflective cup and transmitting light.

[0127] In other embodiments, a double or multi-layer chute 350 may be provided. Figure 18-19 , which is a structural example of a two-layer slide groove 350, is arranged in the same manner as a single-piece arc filter 5 (single-layer slide groove 350), thereby enabling switching use of multiple layers of filters.

[0128] It is understood that the curved filter 5 can be arranged in an upward or downward direction, referring to Figure 15-16 , other structures are the same or similar.

The heat conducting plate on one side of the heat sink 33 has a surface consistent with the shape of the reflective cup 32, and they are installed in a fit with each other, and the other side forms heat dissipation fins or heat sinks. A light exit window is formed at the front end of the lamp holder bracket, and a fixed filter 5' (as a first filter) is installed, which is sealed on the open side of the lamp tube reflective cup 32 to seal the lamp tube 3 in the reflective cup 32.

Fig.37 (b) and Fig.37 (c) shows that the second filter and the third filter are rotated to the horizontal position to close the light outlet. The pulse light emitted by the lamp tube 3 is filtered by the second filter or the third filter after the fixed filter 5', and the output light can directly act on the skin. It can be understood that only one filter 5 can be provided, or multiple layers of filters can be flipped on the inner wall of the light output channel, and each layer of filters can be provided with one or two opposite filters 5.

The semiconductor cooling sheet can use a transparent crystal cold surface as a working surface directly contacting the skin. Alternatively, a transparent crystal cooled by the semiconductor cooling sheet cold surface can be attached to the outside of the semiconductor cooling sheet as a working end surface, or a ring-shaped heat conductive sheet can be set as a working surface to contact the skin.

[0140] Figure 38-47 Another embodiment of a multi-filter photon beauty instrument is that the filter is externally mounted, specifically, the auxiliary head 5000 is sleeved on the working head of the beauty instrument. The embodiments of the built-in filter device 50 of the above embodiments can be arranged in the auxiliary head 5000 and sleeved on the working head of the photon beauty instrument. The auxiliary head is provided with a light exit window 5100 as the light inlet of the auxiliary head, and a fixed filter 5' can be arranged on the light exit window 5100. The light exit window 5100 of the auxiliary head is adapted to the light exit port of the working head 1 of the main body of the beauty instrument. When the auxiliary head is sleeved on the working head, the light exit window 5100 of the auxiliary head is just aligned and connected with the light exit port of the working head 1. By operating the auxiliary head, the filter in the auxiliary head is selected to switch to the light exit port, so that the pulse light generated by the light source of the working head of the beauty instrument is filtered by the filter of the auxiliary head and then emitted, which can be directly used for skin treatment. Figure 38-47 The arrows in the figure indicate the light inlet and light outlet of the accessory head. The accessory head is connected to the working head of the beauty instrument, which is equivalent to a detachable extension part or external part of the working head. It can store one or more filters (fixed filters can be set in the working head) to filter the outgoing light of the light source. This method will bring the following effects: only one accessory head can be installed with more than one filter for manual or automatic switching, which is convenient for storage, easy to clean, low cost, and environmentally friendly.

The interval space between the pair of parallel side walls 5200 and the outer shell of the auxiliary head 5000 forms a cavity 5500 for storing the filter 5 and for the filter 5 to enter and exit. The parallel side walls 5200 are provided with a through slide groove 5300, which connects the light outlet channel with the cavity 5500, so that the filter 5 can slide into or exit the light outlet channel.

[0143] Fig.39 In the auxiliary head embodiment shown, the filter 5 is arc-shaped, and a basic filter (first filter) 5' is fixed by a light outlet window. An arc-shaped filter 5 is installed on the left and right sides of the light outlet channel as the second and third filters. The arc-shaped filter 5 moves from the slide groove 5200 to the light outlet channel or the storage cavity 5300. When it moves into the light outlet channel, it seals the light outlet channel horizontally, filters the incident light, and then emits it from the light outlet. Fig.39 (a)-(c) represent the switching states of the filter, where Fig.39 (a) shows that only the fixed filter 5' filters the incident light, and the second and third filters are stored in the cavity 5300 on both sides. Fig.39 (b) shows that the second filter slides into the light output channel, and the incident light is filtered by the fixed filter 5' and the second filter 5 before being output; Fig.39 (c) indicates that the third filter slides into the light output channel, and the incident light is filtered by the fixed filter 5' and the third filter 5 before being emitted. It can be understood that multi-layer filtering devices can be respectively arranged on both sides of the light output channel, for example, multi-layer filters on each side are arranged in parallel, and combined and adjusted, and multiple filters or multi-layer filters can be switched to enter the light output channel for filtering. The multiple arc filters of this embodiment are switched by rotational motion, and manual pull-out plates / pulls, connecting rods, etc. can be set to realize manual switching. In this embodiment, one or more of the second and third arc filters 5 can adopt the graphene filter 5 of the following embodiments ( Figure 49-5 0), a graphene sheet 500 coating may be further formed on the surface of the filter area to form a composite filter together with the base filter, so that photons of corresponding wavelengths can be obtained for beauty treatment, while the graphene sheet 500 circuit is connected to generate far infrared, and far infrared therapy is achieved at the same time. The positive and negative electrodes of the graphene filter 5 are electrically connected to the control circuit board 90 inside the host through wires, and the electrical connection can be achieved by wires, contacts, interfaces and other existing methods.

[0144] Figure 40-41In the embodiment of the auxiliary head shown, the filter device is designed as a filter soft film, which occupies less space and can adapt to various forms of housings. A pair of rollers 58 are used to roll a filter soft film, and multiple parallel filter areas are set along the transmission direction, which are used as multiple filters 5 respectively. The filter areas corresponding to the filter soft film are transported to the light outlet channel as the second filter by the rotation of the rollers 58. The pair of rollers 58 are accommodated in the storage cavity 5300 on both sides of the light outlet channel and are rotatably installed close to the side wall 5200. The filter soft film is transmitted from the through slide groove 5500 on the side wall across the two sides of the light outlet channel to transmit different filter areas (filters) to the light outlet for filtering. Referring to the above-mentioned embodiment, the roller 58 can be driven to rotate by manual knob or electric method (motor + gear / motor plus synchronous belt / motor + worm, etc.) to switch the filter. In this embodiment, one or more of the multiple filters (or multiple filter regions) of the filter soft film may be the graphene filter 5 ( Figure 49-5 0), a graphene sheet 500 coating may be further formed on the surface of the filter area to form a composite filter together with the base filter, so that the graphene sheet 500 circuit is connected to generate far infrared while obtaining photons of corresponding wavelengths for beauty treatment, and far infrared therapy is achieved at the same time.

The single-side space requirement is relatively small, so it can adapt to more small-shaped products. One or more layers of slide grooves 5500 are provided on the two side walls 5200 of the light output channel. One or more layers of filters 5 slide from the slide grooves 5500 in the storage cavity 5300 on the left and right sides and the light output channel to be stored in the cavity 5300 or enter the light output channel to cover the light output port. In this embodiment, each filter 5 is divided into left and right sub-pieces 5A and 5B, which are simultaneously pushed into the light output channel to be spliced ​​into a whole filter and located at the light output port to filter the incident light. Fig.42 It means 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 It indicates that the second filter (joined by the sub-sheets 5A and 5B on both sides) slides into the light output channel, and the incident light is filtered by the fixed filter 5' and the second filter 5 before being emitted; Fig.44It indicates that the third filter (joined by the sub-sheets 5A and 5B on both sides) slides into the light output channel, and the incident light is filtered by the fixed filter 5' and the third filter 5 before being emitted.

The fixed filter 5' can also adopt a graphene filter, or white glass. The positive and negative electrodes of the graphene filter 5 are electrically connected to the control circuit board 90 inside the host, and are powered by the power supply unit 40.

The graphene sheet 500 can be a graphene film formed on the surface of the base filter 5'' by coating, or a graphene film layer formed on the surface of the base filter 5'' by printing, or a graphene coating formed by other methods. The graphene sheet 500 is a composite film layer on the surface of the base filter 5'', and the adhesion between the layers is strong. The pattern of the graphene sheet 500 on the surface of the base filter 5'' can be designed as needed, and can cover the base filter 5'' in whole or in part. The graphene sheet 500 includes a positive electrode 501 and a negative electrode 502, which are electrically connected to the control circuit board 90 inside the photon beauty instrument to connect the graphene sheet circuit, so that the graphene sheet 500 works and generates far-infrared light to act on the matrix cells, thereby playing a therapeutic role.

[0157] Reference Figure 51-53The photon beauty instrument of this embodiment includes a housing and a light source assembly 30, a power supply unit 40, a cooling fan 60, a radiator assembly and a control circuit board 90 installed in the inner cavity of the housing. The power supply unit 40 supplies power to the light source assembly 30; the control circuit board 90 controls the light source assembly 30 to emit light and generate photons. The housing includes a body housing (specifically, a lower housing 20 and an upper housing 21 that are assembled by snapping) and a front housing 10 at the front end of the body. A light outlet is provided at the front end of the photon beauty instrument. The front housing 10 is installed with a transparent crystal 110 as a working surface, and the rear of the transparent crystal 110 is cooled by a cooling plate 120. The cooling plate 120 can be a semiconductor cooling plate, which can be set in a ring shape, and the middle through hole forms a light channel. The cooling plate 120 is close to the transparent crystal 110. The cooling plate 120 is a ceramic cooling plate. It can be understood that the transparent crystal 110 and the cooling plate 120 can also be set as a semiconductor cooling plate with a transparent crystal cold surface; or, the cooling plate is a heat transfer component made of a heat conductive material such as ceramic; so as to quickly cool the working surface. The transparent crystal 110 covers the front end surface of the cooling plate 120 for contact heat transfer, and a skin sensor 12 is arranged on the edge of the outer wall of the transparent crystal. The skin sensor (or sensor) 12 is electrically connected to the control circuit board 90. The front shell 10 is annular, and the transparent crystal 110 and the cooling plate 120 are fixed by the front shell. The heat dissipation fan 60 is provided with vents such as an air inlet and an air outlet 64. The shell of the beauty instrument is provided with vents such as an air inlet 101 and an air outlet 102, which are connected to the ventilation channel inside the fuselage and the ventilation channel of the heat dissipation fan 60. The air inlet 101 and the air outlet 102 can be one or more groups of through holes on the shell, or can be a gap on the shell, so as to realize air cooling and heat dissipation of the light source assembly. The air inlet and the air outlet can be arranged accordingly according to the position of the light source assembly and / or the radiator assembly inside the beauty instrument.

[0158] 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 beauty instrument body is also provided with buttons, such as a power button 95, a light button 94, etc., which are electrically connected to the control circuit board 90 respectively.

[0159] The light source assembly 30 includes a lamp tube 3 mounted on a lamp holder bracket 35, a reflective cup 32 and a filter device 50 with switchable filters or filter areas. The light source assembly 30 may also be provided with a light source heat sink 33. The light source heat sink 33 may be a fin heat sink or a heat sink or a heat conducting plate or a heat pipe, etc. In a specific example, the heat sink 33 includes a heat conducting plate mounted in contact with the reflective cup and a heat sink arranged on the heat conducting plate. The surface of the heat conducting plate in contact with the reflective cup is consistent with the shape of the reflective cup so as to quickly conduct the heat of the reflective cup to the heat sink for heat dissipation. The reflective cup 32 is mounted outside the lamp tube 3. It can be understood that the light source heat sink 33 may not be provided, and the reflective cup 32 dissipates heat by air cooling.

[0160] The filter device 50 includes one or more filters 5 and a bracket 55 for mounting the filters. The filters 5 can be made by a coating process. The one or more filters 5 are specifically: multiple independent filters or a one-piece filter with multiple filtering areas. The one-piece filter with multiple filtering areas can be coated in a zoned coating manner. The zoned coating is performed on the overall substrate to obtain filters with multiple different wavelength bands. The multiple independent filters can be arranged in two or more than three pieces. Each independent filter can be a filter of a different wavelength band, which can also be made by a coating process. In the present embodiment, the one or more filters 5 are cylindrical or arc-shaped as a whole.

[0161] A pair of annular filter holders 55 are used to install the one or more filters 5 and adjust the position of the filters or filter areas. The side of the annular filter holder 55 is provided with a positioning structure 551 along the circumference to fix the two ends of the filter 5. For example, the side of the annular filter holder 55 is provided with a plurality of convex positions along the circumference, and the ends of the one or more filters 5 are clamped and fixed by adjacent convex positions. When the one or more filters 5 are multiple independent filters combined into an overall cylinder or arc shape, each filter 5 can be installed by the positioning structure (convex position) 551 to form an overall cylindrical shape or an incomplete cylindrical shape, i.e., an arc shape, and each filter 5 is installed on the annular filter holder 55 along the circumferential direction.

[0162] The filter holder 55 can also be arc-shaped or in other shapes, with an annular or arc-shaped mounting edge. A pair of arc-shaped slots 350 are provided on one side of the lamp holder holder 35 where the light source assembly 30 is mounted, and the filter holder 55 can be rotatably mounted in the arc-shaped slots 350, so that the one or more filters 5 are encircled outside the lamp tube 3. The reflective cup 32 is provided outside the lamp tube and the filter. A reflector mask 17 is installed on the lamp holder holder 35, and a light outlet channel is formed inside. The reflector mask 17 is connected to the annular cooling plate 120 and the light outlet. The light outlet channel of the filter holder and the reflector mask 17, and the light outlet channel defined by the cooling plate 120 together form the light outlet channel of the lamp tube, which is connected to the light outlet optical path. The photons generated by the lamp tube are filtered by the filter and transmitted to the working surface by the light outlet channel, and the light is emitted from the light outlet for skin treatment.

[0163] The filter holder 55 is rotated to switch the position of the filter or the filter area, that is, different filters 5 or different filter areas of a one-piece filter are rotated and switched to the light outlet channel, and the light emitted by the light source is filtered by the filter 5 in the light outlet channel to obtain photons with the expected wavelength, which are transmitted to the light outlet port to perform corresponding treatment on the skin in contact with the working surface. In a non-limiting example, the periphery of the annular filter holder 55 can be set to (but not limited to) a tooth shape, that is, the annular filter holder 55 is a gear, so as to manually or electrically adjust the cylindrical multi-piece filter. For example, in a manual method, a manual pull rod passes through a through hole set on the beauty instrument housing and extends from the outside of the body into the body to connect with the filter holder. The user turns the manual pull rod to drive the filter holder 55 to rotate, thereby rotating and switching different filters or different filter areas of the filter into the light outlet channel. In a manual method, the holder 55 can also be directly turned through the through hole on the beauty instrument housing (one side of the holder 55 passes through the through hole). The electric method is, for example, to set a motor and an output gear in the body, and the motor drives the output gear to rotate, and the gear driving wheel and the toothed structure of the filter holder 55 are meshed with each other, driving the filter holder 55 to rotate, thereby rotating and switching different filters or different filter areas (with different filter bands) of a one-piece filter to the light output channel. Other drive / transmission structures in the prior art, such as electromagnets, can also be used to drive the filter holder 55 to rotate.

[0164] The multiple filter areas of the multi-piece filter or the one-piece filter may have different filter bands, and the graphene filter of the above embodiment may also be used. In this embodiment, the filter holder (gear) is rotated by adjusting the motor / electromagnet / manual lever, etc., so as to switch the filter in a smaller space.

[0165] As a preferred embodiment, the one or more filters 5 are formed with ventilation channels 552 to cool the light source assembly. In a non-limiting embodiment, the connection between multiple independent filters 5 (for example, two adjacent independent filters) is formed with ventilation channels 552, or the connection between multiple filter areas (for example, two adjacent filter areas) of a one-piece filter is formed with the ventilation channels 552.

[0166] The lamp tube 3, the reflective cup 3 and the light source heat sink 33 are sleeved inside one or more filters 5, and the heat dissipation duct of the heat sink 33 is connected to the ventilation duct 552 of the one or more filters 5. The heat dissipation duct of the light source heat sink 33 can be connected to the ventilation duct in the beauty instrument body through the ventilation duct 552 of the one or more filters 5.

[0167] In this embodiment, the housing of the photon beauty instrument is provided with a plurality of vents, and a ventilation channel is formed in the housing (body) of the photon beauty instrument. The plurality of vents on the housing are the air inlet 101 and the air outlet 102 of the ventilation channel in the housing, which connect the internal and external air paths of the beauty instrument body. The heat dissipation fan 60 includes a plurality of vents, the interior of which is the ventilation channel of the heat dissipation fan, and the plurality of vents of the heat dissipation fan serve as the air inlet and the air outlet of the ventilation channel of the heat dissipation fan; the ventilation channel of the heat dissipation fan is in air path communication with the ventilation channel in the housing of the photon beauty instrument. The heat dissipation air path of the light source heat sink 33 is in air path communication with the ventilation channel of the heat dissipation fan 60 or with the ventilation channel in the housing of the photon beauty instrument through the ventilation channel 552 of the one or more optical filters 5. As a non-limiting example, a reflective cup air guide sleeve 34 is installed outside the light source assembly, and an air guide channel is arranged inside the reflective cup air guide sleeve 34, which is connected to the ventilation channel 552 of one or more filters 5, and the air guide sleeve 34 is connected to the air inlet or outlet of the fan, so that the ventilation channel of the light source is connected to the ventilation channel of the fan 60 and the ventilation channel in the beauty instrument body. Preferably, when the filter holder is rotated to switch the filter or the filter area is located in the light outlet channel, the ventilation channel 552 of one or more filters 5 is directly opposite to the reflective cup air guide sleeve 34, and is located between the light source heat sink 33 and the reflective cup air guide sleeve 34, so as to better ventilate and dissipate heat. The vents (air inlet 101 or air outlet 102) are arranged on the beauty instrument housing. Cold air enters the beauty instrument body from the air inlet 101, and can enter the heat dissipation duct of the light source heat sink 33 through the vents at both ends of the filter bracket or the ventilation channel 552 of more than one filter, taking away the heat for heat dissipation. The hot air can enter the fan 60 from the air inlet of the heat dissipation fan 60 through the ventilation channel 552 through the air guide channel of the reflective cup air guide sleeve 34, and be discharged from the fan to the air outlet 102 of the beauty instrument housing from the air outlet 64. The lamp tube 3 can be an IPL lamp tube or a halogen lamp or other applicable light source, and is electrically connected to the control circuit board 90. The lamp tube 3, the reflective cup 32, the light source heat sink 33, and the filter device 50 are installed together on the lamp holder bracket 35. A reflector mask 17 is installed at the front end of the lamp holder bracket 35, and the interior thereof is a light outlet channel for transmitting light to the light outlet.

[0168] A heat dissipation component is also provided in the beauty instrument body, and the heat dissipation component includes a heat sink 6, a heat pipe 62, and a heat conductor 63. The heat sink 6 is located on one side of the heat dissipation fan 60, and corresponds to the air inlet 101 or the air outlet 102 provided on the beauty instrument housing. In the photon beauty instrument of this embodiment, the cold air inlet 101 enters the body, absorbs heat through the heat dissipation air duct of the heat sink 6, and the hot air enters the fan from the air inlet on one side of the heat dissipation fan 60, and is discharged from the heat dissipation fan 60 to the air outlet 102 on the beauty instrument housing. One side of the heat conductor 63 contacts the refrigeration sheet 110 for heat transfer, and the other side is connected to one end of the heat pipe 62. The heat sink 6 is installed on the heat pipe 62, so that the heat of the refrigeration sheet 110 is transferred to the heat sink 6 through the heat conductor 63 and the heat pipe 62, so as to achieve the purpose of rapidly cooling the transparent crystal 110.

[0169] It can be understood that the heat dissipation air duct of the heat sink 6 is connected to the ventilation channel of the heat dissipation fan 60 or the ventilation channel in the housing of the photon beauty instrument to perform air cooling and heat dissipation.

[0170] The technical features of the above embodiments can be combined, transformed or replaced to obtain different embodiments, and these embodiments all belong to the disclosure scope of the embodiments of the present application. Some common structures or similar structures in the above embodiments are described in some embodiments but not in other embodiments. These common structures or similar structures are also applicable to these embodiments and belong to the disclosure scope of the embodiments of the present application.

[0171] Combined with reference Figure 53-55 As shown in the figure, the beauty instrument of the above embodiment of the utility model can also use a refrigeration module to cool the working surface. The refrigeration module can be a one-stage refrigeration module or a two-stage refrigeration module. In the one-stage refrigeration module, the hot surface of the semiconductor refrigeration plate is radiated by the heat dissipation fan 60 combined with the heat sink 6, and the working surface and the cold surface of the semiconductor refrigeration plate are connected by a cooling member 62' in a fast cooling manner. At this time, the working surface does not use a semiconductor refrigeration plate.

[0172] The two-stage refrigeration module cools the working surface and can solve the problems of uneven heat conduction efficiency, slow heat conduction, poor timeliness of heat conduction when the first-stage semiconductor refrigeration plate dissipates heat through the heat transfer structural member, which reduces the refrigeration speed, and the problem of uneven heat at the front and rear ends or the left and right ends or the upper and lower ends of the heat sink when the heat is transferred to the heat sink, which affects the effect of fan heat dissipation. The two-stage refrigeration module includes a first-stage semiconductor refrigeration plate 14 and a second-stage semiconductor component 14' and a cooling member 62'; the first-stage and second-stage semiconductor refrigeration plates 14' both include an electric double layer in the middle and hot and cold surfaces at both ends; the cooling member 62' is connected between the first-stage semiconductor refrigeration plate 14 and the second-stage semiconductor refrigeration plate 14' in a fast cooling manner; the cooling member 62' is a heat transfer structural member. The two ends of the cooling member 62' are respectively connected to the hot surface of the first-stage semiconductor refrigeration plate and the cold surface of the second-stage semiconductor refrigeration plate in a fast heat transfer manner; the cooling member 62' is a combination of one or more of a heat conducting component, a heat pipe, a temperature averaging plate, a super heat conducting pipe, and a super heat conducting plate made of a heat conducting material. In a non-limiting example, in conjunction with reference Fig.56 , the super heat conducting pipe is an aluminum superconducting tube, and the super heat conducting plate is an aluminum superconducting plate. The aluminum superconducting plate or aluminum superconducting tube is sealed at both ends, and a working fluid is encapsulated inside; when the aluminum material is formed, more than two microgrooves 611 are formed on the inner wall of the aluminum superconducting plate or aluminum superconducting tube; when the aluminum material is formed, a multi-microporous structure 612 is formed in the aluminum superconducting plate or aluminum superconducting tube material. The through channel 610 inside the aluminum superconducting tube or aluminum superconducting plate is a single channel or multiple channels; the single channel or multiple channels are porous microgrooves channels; the channel 610 and the porous microgrooves 611 on its inner wall are interconnected; the single channel or multiple channels are sealed at both ends, and a working fluid is encapsulated inside.

[0173] As a variant embodiment, the primary semiconductor refrigeration plate 14 is replaced by a transparent crystal working surface or a working surface provided with an optical channel, and the cold surface of the secondary semiconductor component 14' is connected by a cooling member 62' in a fast cooling manner. The cooling member 62' is a combination of one or more selected from a heat-conducting component, a heat pipe, a temperature-averaging plate, a super heat-conducting pipe, and a super heat-conducting plate made of a heat-conducting material. The secondary semiconductor component 14' is cooled by the cooling fan 60 described below, or the hot surface of the secondary semiconductor component 14' is matched with the cooling fan 60 in a fast heat-conducting manner through the heat-conducting structure 65 described below.

[0174] In a non-limiting example, a two-stage cooling method is used, which is mainly used to cool the working surface of the photon beauty instrument and dissipate heat internally, thereby improving the cooling efficiency. The specific implementation method is as follows: a first-stage semiconductor cooling plate 14 is set at the skin contact end, i.e., the working surface, to cool the skin. The heat of the first-stage semiconductor cooling plate 14 is absorbed by the evaporation end of the cooling element (heat pipe / average temperature plate / (aluminum) super heat pipe / (aluminum) super heat plate) 62' and enters the internal channel of the heat pipe / average temperature plate / (aluminum) super heat pipe / (aluminum) super heat plate to transfer the heat to the condensation end. A second-stage semiconductor cooling plate 14' is set at the condensation end to actively cool the condensation end. At this time, the temperature of the condensation end depends on the power of the second-stage semiconductor cooling plate 14'. Since the temperature of the condensation end is much lower than the temperature of the ambient wind, the condensation speed and timeliness of the condensation end are greatly improved, so that the internal phase change cycle of the cooling element (heat pipe / VC / (aluminum) super heat pipe or (aluminum) super heat plate) 62' is accelerated to achieve the beneficial effect of improving the front-end refrigeration; the heat dissipation surface (hot surface) 13 of the secondary semiconductor refrigeration plate 14' is close to the air inlet or outlet of the fan, and the heat dissipation of the secondary semiconductor refrigeration plate 14' can be directly taken away by the fan by copper / aluminum heat conduction plate, or the heat on the heat dissipation surface of the secondary semiconductor refrigeration plate can be conducted to the housing 66 of the fan 60 through the heat pipe / temperature averaging plate / (aluminum) super heat pipe / (aluminum) super heat conduction plate, and discharged through the ventilation channel of the fan by the heat sink 6 set on the fan housing 66. The primary semiconductor refrigeration plate 14 is connected to the working surface of the beauty instrument or directly used as the working surface, and the secondary semiconductor refrigeration plate 14' can be connected to the heat dissipation fan 60 or directly set on the fan housing 66. In the embodiment, the first-level semiconductor refrigeration sheet 14 (specifically the cold surface) can be directly used as a working surface, or used to cool the working surface. When the first-level semiconductor refrigeration sheet 14 is directly used as a working surface, those skilled in the art can set an adaptive shape as needed, for example, a whole piece of transparent crystal is used as the cold surface directly as the working surface, and the hot surface and the electric double layer are provided with an optical channel, so that the first-level semiconductor refrigeration sheet 14 has light transmittance; for example, the cold surface, the hot surface and the electric double layer are arranged in a ring shape or form an optical channel together, and no material limitation is made at this time. When the first-level semiconductor refrigeration sheet 14 is connected to the working surface for cooling, its cold surface contacts the working surface, for example, it is arranged at the periphery of the working surface, or the cold surface of the first-level semiconductor refrigeration sheet 14 and the working surface contact the working surface through a heat transfer component (or heat conducting member).

[0175] A cooling member (first cooling member) 62' is provided to be connected between the primary semiconductor cooling sheet 14 (specifically its hot surface) and the secondary semiconductor cooling sheet 14' (specifically its cold surface) in a fast cooling manner; the heat of the primary semiconductor cooling sheet 14 can be quickly transferred to the secondary semiconductor cooling sheet 14', so as to achieve the effect of cooling the working surface. The cooling member 62' is a heat transfer structural member, and the heat transfer structural member can be a heat conducting material such as (not limited to) a heat conducting component made of a metal material such as a copper tube or a copper plate or other heat transfer structures, etc.; preferably a heat pipe (heat pipe) or a vapor chamber or an (aluminum) super heat conducting pipe or a (aluminum) super heat conducting plate. The cooling member 62' can be designed to be adapted in shape according to the shape of the primary semiconductor cooling sheet 14 and the secondary semiconductor cooling sheet 14', with the principle of fast heat dissipation. When the primary semiconductor cooling sheet 14 is directly used as the working surface, it has light transmittance or is provided with a light channel. The end of the cooling member 62' in contact with the working surface can be designed to be annular, in close contact with the periphery of the hot surface of the primary semiconductor cooling plate 14, so as to quickly absorb the heat of the primary semiconductor cooling plate 14 or the surrounding environment of the primary semiconductor cooling plate 14; the end of the cooling member 62' in contact with the secondary semiconductor cooling plate 14' can be designed to extend a predetermined length from the annular bend and be placed on the cold surface of the secondary semiconductor cooling plate 14' and in close contact with the cold surface. Alternatively, a cooling member 63 is provided between the cooling member 62' and the secondary semiconductor cooling plate 14' to facilitate close contact heat transfer.

[0176] The secondary semiconductor cooling sheet 14' enhances the heat dissipation effect through the heat dissipation assembly. The heat dissipation assembly includes a heat-conducting shell 68 formed by heat pipes or (aluminum) super heat-conducting pipes or (aluminum) super heat-conducting plates or temperature-averaging plates in a single piece or in a multi-piece manner, and a heat sink 6 arranged on the heat-conducting shell 68. The heat surface of the secondary semiconductor cooling sheet is arranged on the outer wall of the heat-conducting shell 68, or the heat-conducting shell 68 directly serves as the heat surface of the semiconductor cooling sheet 14'. The heat-conducting shell 68 is used for heat dissipation of the secondary semiconductor cooling sheet 14'. When applied to a beauty instrument, the heat-conducting shell 68 is located in the ventilation channel of the body; the secondary semiconductor refrigeration plate 14' is arranged on the heat-conducting shell 68, and the hot surface of the secondary semiconductor refrigeration plate is fitted on the outer wall of the heat-conducting shell 68, so that the heat of the hot surface is directly transferred to the heat-conducting shell 68; or, the hot surface of the secondary semiconductor refrigeration plate 14' is installed on the outer wall of the heat-conducting shell 68 (heat pipe / temperature averaging plate / (aluminum) super heat-conducting pipe / (aluminum) super heat-conducting plate) through a heat-conducting member, and the heat of the hot surface is quickly transferred to the heat-conducting shell 68 (heat pipe / temperature averaging plate / (aluminum) super heat-conducting pipe / (aluminum) super heat-conducting plate) through the heat-conducting member; or, the hot end circuit of the semiconductor refrigeration plate is arranged on the heat-conducting shell 68 (heat pipe / temperature averaging plate / (aluminum) super heat-conducting pipe / (aluminum) super heat-conducting plate), which is welded and electrically connected to the PN galvanic particles of the galvanic layer. Preferably, a temperature averaging plate / (aluminum) super heat conducting plate is used as a whole single piece or multiple pieces are spliced ​​to form a heat conducting housing 68. As a non-limiting example, one end of the heat conducting housing 68 forms an extended platform for setting or installing the secondary semiconductor cooling sheet 14'. The area of ​​the heat conducting housing 68 is larger than the electric double layer and the cold surface, so that the heat dissipation area of ​​the hot surface of the secondary semiconductor cooling sheet 14' is increased.

[0177] The heat sink 6 is provided on the heat-conducting housing 68 to increase the heat dissipation area. The heat sink 6 can be provided on the upper surface or the lower surface or both surfaces of the heat-conducting housing 68 according to the heat dissipation requirements of the product.
