[0098] Some embodiments of the present disclosure are described in detail. In the absence of conflict, the following embodiments and features of the embodiments can be combined with each other.

[0102] See also Figures 3 to 5In this embodiment, the device body 10 mainly includes a housing 12, an optical system 13, a light source bracket 14, a light-transmitting bracket 15, a heat dissipation system 16, a main control board 17 and a power supply 18. The light source bracket 14, the light-transmitting bracket 15, the optical system 13, the heat dissipation system 16, the main control board 17 and the power supply 18 are respectively installed in the housing 12. The optical system 13 is used to provide processing light or cooperate with the filter component 11 to provide processing light, the light source bracket 14 and the light-transmitting bracket 15 are used to provide support for the optical system 13 or other components, the heat dissipation system 16 is used to dissipate heat for the skin treatment device 1000, the main control board 17 is used to control the optical system 13 to emit light and / or control the heat dissipation system 16 to operate and dissipate heat, and the power supply 18 supplies power to various electrical components (such as the main control board 17).

[0103] See also Figure 4 and Figure 5 In this embodiment, the housing 12 has an internal space Q1 and a light outlet K1. The internal space Q1 is used to accommodate other components of the skin treatment device 1000 (such as the light source bracket 14, the light-transmitting bracket 15, the optical system 13, etc.), and the light outlet K1 is used for the treatment light generated by the skin treatment device 1000 to be emitted along the light emitting direction X. The treatment light refers to light that can be irradiated on the skin to treat the skin, such as continuous light or intense pulsed light that meets certain conditions.

[0104] In this embodiment, the housing 12 includes an upper housing 19, a lower housing 20 and a front housing 21, and the upper housing 19, the lower housing 20 and the front housing 21 enclose an internal space Q1. The light outlet K1 is provided in the front housing 21. The upper housing 19, the lower housing 20 and the front housing 21 may be detachably connected, for example, by screw connection, bonding, clamping connection, etc.

[0105] In other embodiments, the shell 12 may be divided in other forms, such as being composed of an upper and lower half shell, which is not limited here.

[0106] In this embodiment, the housing 12 is provided with an insertion port K2 , and the insertion port K2 is used as an entrance and exit for inserting and removing the filter assembly 11 from the device body 10 .

[0107] In this embodiment, the main control board 17 may be a printed circuit board (PCB), which may be fixedly installed in the internal space Q1 by screw connection or other means.

[0108] The power supply 18 is installed in the internal space Q1 and is electrically connected to the main control board 17 , and is used to supply power to the main control board 17 and to supply power to other electrical components of the skin treatment device 1000 through the main control board 17 .

[0109] The power source 18 can be a rechargeable battery to facilitate replenishing electrical energy.

[0110] The optical system 13 includes a light source 22, a reflective cup 24, a fixed filter 25 and a light-transmitting element 26. The light generated by the light source 22 is reflected by the reflective cup 24 in the light-emitting direction X, and then filtered by the filter assembly 11 (if installed) and the fixed filter 25, and then emitted after passing through the light-transmitting element 26. The light emitted from the light-transmitting element 26 can be used as treatment light for skin treatment. Of course, other optical elements, such as another filter element, can be arranged on the optical path as needed, which is not limited here.

[0111] The light source 22 is used to generate light. In this embodiment, the light source 22 is a lamp tube 23, which can be fixedly connected and electrically connected to the main control board 17, and the lamp tube 23 can be controlled by the main control board 17 to generate light.

[0112] According to the different types of light generated by the lamp tube 23, the skin treatment device 1000 can be divided into different types. For example, the lamp tube 23 can be used to generate laser, which is a laser lamp tube, and the skin treatment device 1000 is a laser skin treatment device 1000; for example, the lamp tube 23 can be used to generate IPL light (Intense Pulsed Light), which is an IPL lamp tube (such as a xenon lamp, etc.), and the skin treatment device 1000 is an intense pulsed light skin treatment device 1000; for example, the lamp tube 23 can be an LED lamp tube, and so on.

[0113] In this embodiment, the lamp tube 23 is mainly used as a xenon lamp as an example for explanation. The light-emitting principle of this type of skin treatment device 1000 is: the capacitor is connected to the power supply 18, and the transformer component boosts the voltage to charge the capacitor. When the capacitor is charged to a preset value and the controller receives a trigger signal, the electric energy in the capacitor is released, and the instantaneous voltage can reach several hundred volts, thereby stimulating the lamp tube 23 to instantly release strong pulsed light, thereby completing one light emission.

[0114] In other embodiments, the light source 22 may also be other types or shapes other than the lamp tube 23, such as a single or multiple point light sources, etc., which is not limited here.

[0115] Continue to see Figure 4 and Figure 5 , the light source bracket 14 is installed in the internal space Q1. Optionally, the light source bracket 14 can be directly or indirectly fixedly connected to the housing 12, and the fixing method can be a snap connection, a threaded connection or other suitable connection methods.

[0116] The light source bracket 14 has a mounting cavity Q2 , the reflector cup 24 is disposed in the mounting cavity Q2 , the lamp tube 23 extends into the mounting cavity Q2 , and is disposed on a side of the reflector cup 24 away from the light source bracket 14 .

[0117] Continue to see Figure 4 and Figure 5The light-transmitting bracket 15 is installed in the internal space Q1. Optionally, the light-transmitting bracket 15 can be directly or indirectly fixedly connected to the housing 12, and the fixing method can be a snap connection, a threaded connection or other suitable connection methods.

[0118] In this embodiment, the light-transmitting bracket 15 is connected to the front end of the light source bracket 14 in the light-emitting direction X, and is used to install components such as the light-transmitting member 26, the fixed filter 25, and the filter assembly 11. The light-transmitting bracket 15 is provided with a slot C2, and the slot C2 is correspondingly connected to the plug-in port K2 on the housing 12, and is used to accommodate the inserted filter assembly 11. In this way, the filter assembly 11 can be inserted from the plug-in port K2 of the housing 12 and fit into the slot C2 of the light-transmitting bracket 15 of the device body 10, or pulled out from the slot C2 of the light-transmitting bracket 15 of the device body 10. The light-transmitting bracket 15 has a light-emitting channel T3 (also shown in Figure 6 ), one end of the light outlet channel T3 is connected to the mounting cavity Q2 of the light source bracket 14, and the other end corresponds to the light outlet K1 of the housing 12. It should be noted that the light-transmitting bracket 15 mentioned in this embodiment means that its light outlet channel T3 can allow light to pass through, and does not mean that the material of the light-transmitting bracket 15 itself is a light-transmitting material.

[0119] In this embodiment, one end of the light-transmitting member 26 is mounted on the light-emitting channel T3 of the light-transmitting bracket 15 , and the other end thereof extends into the light-emitting port K1 matched with the front shell 21 of the housing 12 .

[0120] The light-transmitting member 26 can be a light-transmitting crystal, such as sapphire. The surface on the light-emitting side thereof can be used as the light-emitting surface and can also be used to fit the skin. In this way, when in use, the heat generated by the skin due to the light-processing can be conducted to the light-transmitting member 26, reducing the burning sensation of the skin, achieving an ice-compression effect, and improving the user experience. Of course, the light-transmitting member 26 can also be made of other suitable optical materials, which is not limited here.

[0121] In this embodiment, the fixed filter 25 is installed in the light outlet channel T3 of the light-transmitting bracket 15 and is located between the light-transmitting member 26 and the reflective cup 24 .

[0122] The fixed optical filter 25 can filter the light emitted by the lamp tube 23 to select the light of the required wavelength for emission. There can be one or more fixed optical filters 25 to achieve a combined filtering effect.

[0123] In this embodiment, optionally, the fixed filter 25 can be installed in the light output channel T3 of the light-transmitting bracket 15 through a fixing frame 97 .

[0124] Continue to see Figures 4 to 5 The filter assembly 11 in this embodiment can be inserted into the slot C2 that matches the light-transmitting bracket 15, and can also be pulled out from the slot C2.

[0125] In this embodiment, the filter assembly 11 and the slot C2 may be located on a side of the fixed filter 25 away from the light-transmitting member 26. In other embodiments, the filter assembly 11 and the slot C2 may also be located between the fixed filter 25 and the light-transmitting member 26.

[0126] In this embodiment, the light-transmitting member 26, the fixed filter 25, and the filter assembly 11 correspond to the lamp tube 23 and the reflective cup 24 in sequence along the light-emitting direction X. In this way, the light emitted by the lamp tube 23 is directly or reflected and focused by the reflective cup 24, filtered by the filter assembly 11 and the fixed filter 25, and then emitted through the light-transmitting member 26 for light treatment of the skin.

[0127] In this embodiment, the filter assembly 11 is configured to be pluggable, so the skin treatment device 1000 can be used with or without the filter assembly 11. Alternatively, the skin treatment device 1000 can be configured with a plurality of filter assemblies 11 of different models so that they can be selected as needed. The filter assemblies 11 of different models are, for example, filter assemblies 11 that can filter light of different wavelength bands. When different filtering requirements need to be achieved, filter assemblies 11 of different models can be plugged in.

[0128] The skin treatment device 1000 in this embodiment also has a sensing function for sensing whether the filter component 11 is plugged in place and / or for sensing and identifying the model of the plugged filter component 11.

[0129] See also Figure 6 and Figure 7 In order to identify the model of the filter component 11, in this embodiment, the filter component 11 is provided with an identification area M1, and the device body 10 is provided with a sensing component 48. When the filter component 11 is plugged into the slot C2 of the light-transmitting bracket 15, the identification area M1 is sensed by the sensing component 48, thereby obtaining the model information of the filter component 11.

[0130] This information can be transmitted from the sensing component 48 to the main control board 17 (see Figure 4 ), and after being processed by the main control board 17, it is manifested in a form that can be perceived by the user (such as image, sound, vibration, etc.).

[0131] For example, a visual display screen may be provided on the skin treatment device 1000, and when the main control board 17 receives a signal reflecting the model of the filter assembly 11, the corresponding model information (such as wavelength information of filtered light) is presented on the display screen in text form.

[0132] Continue to see Figure 6 and Figure 7In this embodiment, the light-transmitting bracket 15 may include four peripheral side panels, and the four peripheral side walls form a rectangular frame structure. The four peripheral side panels are respectively named as the first peripheral side panel 28, the second peripheral side panel 29, the third peripheral side panel 30 and the fourth peripheral side panel 31. The first peripheral side panel 28 and the second peripheral side panel 29 are opposite to each other along the plug-in direction Y1, and the third peripheral side panel 30 and the fourth peripheral side panel 31 are opposite to each other.

[0133] The entrance of the slot C2 is disposed at one side of the first peripheral side plate 28 , so that the filter assembly 11 can be inserted into the slot C2 from one side of the first peripheral side plate 28 .

[0134] The third peripheral side plate 30 is located close to the upper shell 19 , and the fourth peripheral side plate 31 is located close to the lower shell 20 .

[0135] In this embodiment, the first peripheral side plate 28, the fourth peripheral side plate 31 and the second peripheral side plate 29 can be optionally combined into an integrated U-shaped frame 32, and the third peripheral side plate 30 is used as a cover plate 33, and the cover plate 33 is detachably covered on the opening of the U-shaped frame 32, so as to enclose the light outlet channel T3 of the light-transmitting bracket 15. In this way, when it is necessary to install the light-transmitting member 26 and the fixed filter 25 on the light-transmitting bracket 15, the light-transmitting member 26 and the fixed filter 25 can be conveniently installed from one side of the opening of the U-shaped frame 32, and then the cover plate 33 can be covered, which has a simple structure and is easy to assemble.

[0136] In other embodiments, the first peripheral side plate 28, the second peripheral side plate 29, the third peripheral side plate 30 and the fourth peripheral side plate 31 may also be designed in whole or in part as one piece, which is not limited here. For example, the first peripheral side plate 28 and the third peripheral side plate 30 may be one piece, the second peripheral side plate 29 and the fourth peripheral side plate 31 may be one piece, and so on.

[0137] The light-transmitting bracket 15 in this embodiment can also be configured into other shapes as required, which is not limited here.

[0138] See also Figure 7 and Figure 8 In this embodiment, the sensing component 48 includes a sensing circuit board 49 and a filter model identification circuit 60 disposed on the sensing circuit board 49; the filter model identification circuit 60 includes a plurality of conductive springs 104 spaced apart from each other, and the conductive springs 104 are fixed to the sensing circuit board 49. A recognition area M1 is provided on one side in the thickness direction of the filter component 11. When the filter component 11 is fitted into the slot C2, the plurality of conductive springs 104 are elastically connected to the recognition area M1, and the recognition areas M1 of filter components 11 of different models conduct different combinations of the plurality of conductive springs 104.

[0139] like Figure 7As shown in FIG. 1 , the device body 10 of the skin treatment device 1000 is configured with a plurality of filter components 11 of different models, and the plurality of different filter components 11 have different identification areas M1 .

[0140] The identification area M1 includes a conductive area M11 and an air-avoiding area M12, wherein the conductive area M11 is made of a conductive material, and the air-avoiding area M12 is a groove that is concave from the conductive area M11 to a side away from the conductive spring 104. Some of the multiple conductive springs 104 are elastically connected to the conductive area M11, and the other conductive springs 104 correspond to the grooves. In this way, the conductive springs 104 elastically connected to the conductive area M11 are mutually conductive through the conductive area M11, while the conductive springs 104 corresponding to the grooves are not conductive. For different types of filter components 11, they have different numbers and / or distribution positions of grooves, so that inserting different filter components 11 can make different combinations of conductive springs 104 conductive, and then make the filter model identification circuit 60 have different electrical parameters (such as current, voltage, resistance, etc.). In this way, by detecting the electrical parameters, the model identification of the filter component 11 can be achieved. Of course, how to make the filter model identification circuit 60 have different electrical parameters by conducting different combinations of conductive springs 104 can be designed using common detection / identification circuit design methods, which will not be described in detail here.

[0141] Continue to see Figures 6 to 8 In this embodiment, the sensing circuit board 49 is mounted on the light-transmitting bracket 15, for example, fixed on the outer side of the second peripheral side plate 29. Specifically, a lower bearing plate portion 31a can be convexly provided on the outer side of the second peripheral side plate 29, and the lower bearing plate portion 31a can be flush with the fourth peripheral side plate 31, and the third peripheral side plate 30 (i.e., the cover plate 33) has an upper bearing plate portion 30a corresponding to the lower bearing plate portion 31a, and the sensing circuit board 49 is fixedly clamped between the lower bearing plate portion 31a and the upper bearing plate portion 30a. Optionally, the surface of the lower bearing plate portion 31a and / or the upper bearing plate portion 30a facing the sensing circuit board 49 can be concavely provided with a mating groove C10, and the two sides of the sensing circuit board 49 are respectively positioned and mated in the two mating grooves C10 to ensure that the sensing circuit board 49 is reliably fixed. Correspondingly, the slot C2 penetrates the second peripheral side plate 29 , so that when the filter assembly 11 is inserted into place, the rear end of the filter assembly 11 (the end away from the plug-in port K2 ) extends out of the second peripheral side plate 29 to cooperate with the conductive spring 104 .

[0142] In this embodiment, the sensing circuit board 49 is arranged in the space between the second peripheral side plate 29 and the housing 12, so that the space is fully utilized and the structure is more compact and reasonable.

[0143] In other embodiments, the sensing circuit board 49 may also be arranged on the inner side of the second peripheral side plate 29 or at other suitable positions, which is not limited here.

[0144] In this embodiment, the surface of the sensing circuit board 49 faces the filter assembly 11, and the plurality of conductive springs 104 extend from the sensing circuit board 49 toward the surface of the filter assembly 11. Optionally, the sensing circuit board 49 is located in front of the slot C2 along the light emitting direction X.

[0145] Optionally, the sensing component 48 further includes a shrapnel rack 105 (also see Fig. 9 ), the spring holder 105 is fixed to the board surface of the sensing circuit board 49 facing the filter assembly 11. The conductive spring 104 is supported by the spring holder 105, and the conductive spring 104 includes a welding piece 106 and a conductive contact portion 107; the welding piece 106 is located on the side of the spring holder 105 close to the sensing circuit board 49, the welding piece 106 is welded and fixed to the sensing circuit board 49, and is electrically connected to the filter model identification circuit 60; the conductive contact portion 107 is located on the side of the spring holder 105 close to the filter assembly 11, and is used to elastically press and contact the conductive area M11.

[0146] Optionally, the sensing component 48 further includes a wiring socket 108 , which is electrically connected to the sensing circuit board 49 and is used to electrically connect the sensing circuit board 49 to the main control board 17 of the skin treatment device 1000 .

[0147] Main references Fig.10 The optical filter assembly 11 provided in this embodiment includes an optical filter mounting frame 62 and an optical filter 63, wherein the optical filter 63 is mounted on the optical filter mounting frame 62; the optical filter mounting frame 62 includes a metal frame member 109, a tail member 116 and a holding head 65. The metal frame member 109 has a light transmission area S1 and a filter slot C5, wherein the filter slot C5 extends along the plug-in direction Y1 of the optical filter assembly 11, and the light transmission area S1 is connected to the filter slot C5; the optical filter 63 is matched with the filter slot C5 and covers the light transmission area S1; the tail member 116 and the holding head 65 are respectively connected to the two ends of the metal frame member 109 along the plug-in direction Y1, and the optical filter 63 is sandwiched between the tail member 116 and the holding head 65. The conductive area M11 is the portion of the tail of the metal frame 109 close to the sensing circuit board 49 , and the groove serving as the air avoidance area M12 is opened in the conductive area M11 of the metal frame 109 (i.e., the portion of the tail of the metal frame 109 close to the sensing circuit board 49 ).

[0148] The metal frame 109 includes a first metal plate 110, a second metal plate 111 and two side metal plates 112; the first metal plate 110 and the second metal plate 111 are spaced apart along the thickness direction of the filter assembly 11, and the two side metal plates 112 are respectively connected to the first metal plate 110 and the second metal plate 111 to enclose a filter slot C5 for installing the filter 63. The holding head 65 and the tail end piece 116 are respectively plugged into and fitted at both ends of the filter slot C5 and clamped at both ends of the filter 63. The first metal plate 110 and the second metal plate 111 are provided with opposite light-transmitting holes, and the light-transmitting holes form the light-transmitting area S1.

[0149] The first metal plate 110 faces the sensing circuit board 49 , and a portion of the first metal plate 110 close to one end of the tail piece 116 serves as the conductive area M11 and is provided with a groove.

[0150] Thus, when the filter assembly 11 is inserted, the tail end of the metal frame member 109 of the filter assembly 11 as the conductive area M11 corresponds to the conductive spring 104. The conductive springs 104 corresponding to the grooves as the escape area M12 among the plurality of conductive springs 104 are not conducted by the conductive area M11. The conductive springs 104 not corresponding to the escape area M12 among the plurality of conductive springs 104 elastically abut against the first metal plate 110 of the metal frame member 109, and are thus electrically conducted by the first metal plate 110.

[0151] In this embodiment, optionally, there are six conductive springs 104 on the sensing circuit board 49, and the six conductive springs 104 are arranged in a row. The number or position of the grooves of different models of filter components 11 are different. Figure 7 Three different types of filter components 11 are shown by dotted lines, and the groove arrangement positions and quantities of the three are different, so that the three different types of filter components 11 can achieve conduction of different conductive springs 104, so that the model of the inserted filter component 11 can be identified.

[0152] Figures 11 to 13 A filter component 11d of another structure is given. The filter component 11d also has an identification area M1 for the sensing component 48 to identify the model of the filter component 11d.

[0153] The identification area M1 of the filter assembly 11d includes a conductive area M21 and a non-conductive area M22, wherein the conductive area M21 is made of a conductive material (such as metal), and the non-conductive area M22 is made of an insulating material. When the filter assembly 11d is inserted into the slot C2, some of the conductive springs 104 are elastically connected to the conductive area M21, and the other conductive springs 104 are elastically connected to the non-conductive area M22. The distribution positions of the conductive area M21 and the non-conductive area M22 of the filter assembly 11d of different models are different, so that the identification area M1 of the filter assembly 11d of different models conducts different combinations of the conductive springs 104.

[0154] By providing a non-conductive area M22 capable of supporting the conductive spring pieces 104 to replace the avoidance area M12 of the aforementioned filter component 11, when the filter component 11d is inserted, all the conductive spring pieces 104 can abut against the filter component 11d, ensuring that all the conductive spring pieces 104 are subjected to substantially uniform elastic deformation.

[0155] See also Figure 11 to Figure 12 The filter assembly 11d in this embodiment includes a filter mounting frame 62 and a filter 63, and the filter 63 is mounted on the filter mounting frame 62. The filter mounting frame 62 includes a metal frame member 109, a tail member 116 and a holding head 65.

[0156] The metal frame member 109 of the filter assembly 11d includes a third metal plate 113 and two folded edges 114; the two folded edges 114 are respectively connected to the two sides of the width direction of the third metal plate 113, and the filter slot C5 for installing the filter 63 is defined between the two folded edges 114 and the third metal plate 113. The holding head 65 and the tail end member 116 are respectively connected to the two ends of the third metal plate 113 and clamped at the two ends of the filter 63. The third metal plate 113 is provided with opposite light-transmitting holes, and the light-transmitting holes form the light-transmitting area S1.

[0157] The portion of the third metal plate 113 near the end of the tail piece 116 serves as the conductive area M21, and a notch C8 is provided at the conductive area M21. The notch C8 is recessed by a certain length from the end surface of the third metal plate 113 near the end of the tail piece 116. The tail piece 116 has an insulating protrusion 115. When the tail piece 116 is plugged into the third metal plate 113, the insulating protrusion 115 fits in the notch C8, and the surface of the insulating protrusion 115 is flush with the surface of the conductive area M21, serving as a non-conductive area M22.

[0158] Thus, when the filter assembly 11d is inserted into the slot C2, the conductive spring piece 104 abutting against the third metal plate 113 is conducted, while the conductive spring piece 104 abutting against the insulating protrusion 115 at the notch C8 is not conducted.

[0159] Different types of filter components 11d have different notches C8 and insulating protrusions 115, such as Fig.13 Two different types of filter components 11d are shown, wherein the filter component 11d on the right has two insulating protrusions 115 as non-conductive areas M22, which is different from the filter component 11d on the left having only one insulating protrusion 115. Thus, after being inserted into the slot C2, the types of the two different types of filter components 11d on the left and right can be identified.
