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.

[0078] 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.

[0079] 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 front and rear walls of the hollow space 351 serve as movement limits for the internal thread shaft hole 520.

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 output window / light output channel at the front end of the lamp holder bracket 35.

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), after the lamp 3 is exposed, the emitted light passes through the first filter (the filter band is 500-1200nm), and the emitted light can directly act on the skin. Fig.11 (b), after the light of the lamp tube 3 is exposed, it passes through the first filter (500-1200nm) and then passes 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, and the lamp tube 3, the reflective cup 32, and the light source heat sink 33 are installed and fixed. The front end surface forms a light outlet window, and the two 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, and 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, and are 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 manually operated to switch different filters into / out of the light channel 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 setting a corresponding movable guide track or slot. Alternatively, an electric push rod or other electric push-pull mechanism of the prior art is set inside the beauty instrument and electrically connected to the control circuit board 90 to automatically control the filter to be pushed in or pulled out for automatic adjustment.

In other embodiments, the fixed filter 5' may not be provided, refer to Fig.12 (a), 13(a), 14(a). In this embodiment, the slide groove 350 for the filter to be moved and switched is arranged on the opposite side walls of the light outlet channel at the front end of the lamp holder bracket 35, and the slide groove 350 is an arc-shaped groove, which is adapted to the arc-shaped filter 5.

As an embodiment, a rack is arranged on the arc-shaped filter bracket 55 for fixing the arc-shaped filter 5, and a gear driven by a motor can be arranged in the body or the working head. The gear is engaged with the rack of the filter bracket to drive the filter bracket 55 to rotate, thereby moving the arc-shaped filter 5, so that the corresponding filter area or filter rotates to the light outlet channel for filtering. Similarly, a manual dial connected to the filter bracket 55 can be arranged, or the outer edge of the filter bracket 55 can be directly protruded and arranged on the beauty instrument housing, and the filter bracket 55 can be manually dialed in cooperation with the guide track or guide groove, so as to move and switch different filters.

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 correspond 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.

[0102] It can be understood that the manual dial connected to the filter assembly described in the above embodiment can be provided on the accessory head 5000, or the edge of the filter holder can be made to protrude outside the housing, so as to facilitate manual adjustment of the position of the filter in the accessory head. The electric adjustment mechanism in the above embodiment can also be provided on the accessory head, and a sub-circuit board and / or a connector can be provided on the accessory head, and a connector can be correspondingly provided on the main body of the beauty instrument. When the accessory head is sleeved on the working head, the internal circuit of the accessory head is electrically connected to the internal circuit / control circuit board 90 of the main body, thereby realizing electric adjustment of the filter position.

[0103] Fig.38The figure shows a schematic diagram of the structure of the auxiliary head 5000, in which a light outlet window 5100 is arranged at the center of the top surface as a light inlet, and a pair of parallel side walls 5200 are arranged inside, and the interval in the middle forms a light outlet channel, i.e., the light outlet. 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.

[0104] 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 adjustment can switch multiple filters or multi-layer filters into the light output channel for filtering. The multiple arc filters of this embodiment are switched by rotating motion, and manual pull-out plates / pulls, connecting rods, etc. can be set to achieve manual switching.

[0105] Figure 40-41 In the embodiment of the auxiliary head shown, the filter device is a filter soft film design, 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 twisting or electric means (motor + gear / motor plus synchronous belt / motor + worm, etc.) to switch the filter.

[0106] Figure 42-44 In the auxiliary head embodiment shown, the filter device is in the form of spliced ​​filters 5 inserted on both sides of the light output channel. 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.44 It 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.

[0107] Reference Figures 45-47 The photon beauty instrument accessory head shown in the figure, in this embodiment, the filter device is an inner flip filter solution, which has a small space and can adapt to all forms of beauty instruments and accessory heads, that is, it is suitable for various shapes and space designs. The inner walls of the two side walls 5200 of the light outlet channel are provided with a rotation center 6 formed by a pivot or hinge structure, and a filter 5 is installed respectively, as the second filter and the third filter. The two filters 5 can be flipped around the rotation center 6 in the light outlet channel, for example, flipped between the vertical position and the horizontal position, and rotated to the light outlet in the light outlet channel perpendicular to the light outlet direction, parallel to the fixed filter 5'. Fig.45 The two filters (second filter and third filter) are shown located on the inner wall of the storage position. Fig.46 and Fig.47 The second filter and the third filter are shown to be rotated to the horizontal position to close the light outlet. The pulse light passes through the fixed filter 5' and then is filtered by the second filter or the third filter, and the output light can act directly on the skin. It can be understood that only one filter 5 can be provided, or a multi-layer filter device can be flipped on the inner wall of the light outlet channel, and each layer of the filter device can be provided with one or two opposite filters 5.
