[0082] See also Figure 3 and Figure 4 In 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).

[0083] 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.

[0084] 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.

[0085] 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.

[0086] 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.

[0087] The main control board 17 may have a switch element. When a user presses a button cover to expose the housing 12 , the button cover will press down the switch element to start or stop the skin treatment device 1000 .

[0088] 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 .

[0089] The power source 18 can be a rechargeable battery to facilitate replenishing electrical energy.

[0090] See also Figure 5 and Figure 6 The optical system 13 includes a light source 22, a reflective cup 24, a fixed filter 25 and a light-transmitting member 26. The light generated by the light source 22 is reflected in the light-emitting direction X by the reflective cup 24, and then filtered by the filter assembly 11 and the fixed filter 25 respectively, and then emitted after passing through the light-transmitting member 26. The light emitted from the light-transmitting member 26 can be used as treatment light for skin treatment.

[0091] The light source 22 is used to generate light. In this embodiment, the light source 22 is a lamp tube 23, which is fixedly connected and electrically connected to the main control board 17 (see Figure 3 ), the lamp tube 23 can generate light under the control of the main control board 17.

[0092] 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; 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; for example, the lamp tube 23 can be an LED lamp tube, and so on.

[0093] 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.

[0094] 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.

[0095] Continue to see Figure 5 and Figure 6 , 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.

[0096] The light source support 14 has a mounting cavity Q2, a reflector cup 24 is disposed in the mounting cavity Q2, and a lamp tube 23 extends into the mounting cavity Q2 and is disposed on the side of the reflector cup 24 away from the light source support 14. The lamp tube 23 can be connected to the mounting cavity Q2 by a power connection pin 27 (see FIG. Figure 3 ) is electrically connected and fixedly connected to the main control board 17. In this way, the light emitted by the light source 22 can be reflected toward the light emitting direction X through the reflective cup 24.

[0097] Continue to see Figure 5 and Figure 6 The 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.

[0098] 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 for accommodating the inserted filter assembly 11.

[0099] Optionally, the front end of the light-transmitting bracket 15 in the light-emitting direction X is connected to the front shell 21 to improve the installation firmness of the light-transmitting bracket 15. The light-transmitting bracket 15 has a light-emitting channel T3, one end of which is connected to the installation cavity Q2 of the light source bracket 14, and the other end corresponds to the light-emitting port K1 of the shell 12. It should be noted that the light-transmitting bracket 15 mentioned in this embodiment refers to the light-emitting channel T3 that can allow light to pass through, and does not mean that the material itself is a light-transmitting material.

[0100] In this embodiment, the light-transmitting bracket 15 can be configured as a rectangular frame mainly surrounded by four peripheral side panels. 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.

[0101] 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 .

[0102] 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 .

[0103] 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 (see Fig. 9 ), the third peripheral side plate 30 is used as a cover plate 33, and the cover plate 33 can be 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.

[0104] 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.

[0105] Continue to see Figure 5 and Figure 6 In this embodiment, one end of the light-transmitting member 26 is installed in the light-emitting channel T3 of the light-transmitting bracket 15 , and the other end extends into the light-emitting port K1 on the front shell 21 of the housing 12 .

[0106] 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.

[0107] 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 .

[0108] 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.

[0109] 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 .

[0110] Continue to see Figure 5 and Figure 6 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.

[0111] 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.

[0112] 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.

[0113] See also Figure 7-Figure 9 In this embodiment, the skin treatment device 1000 is further provided with a skin color recognition component 34. The skin color recognition component 34 is used to recognize the skin color of the object to be treated.

[0114] When in use, the skin color of the object to be treated can be identified in advance by the skin color identification component 34, and then the appropriate filter component 11 is selected according to the skin color, and / or appropriate parameters (such as light output power) are set, and then the skin of the object to be treated is treated by the treatment light. For the skin color that is not suitable for the current skin treatment device 1000 to treat, the skin treatment can be stopped or replaced with other treatment equipment to avoid invalid treatment operations or damage to the skin during the treatment process.

[0115] In addition, the skin color of different parts of the same treatment object may be different. For example, the skin of more exposed parts such as arms and calves may be darker, while the skin of parts of the body that are usually covered by clothes may be lighter. The skin color recognition component 34 in this embodiment can also be used in real time with the treatment light during skin treatment. For example, during the process or interval of the treatment light treating the skin, the skin color information of the current treatment part is obtained in real time through the skin color recognition component 34, so as to control the skin treatment device 1000 to adjust appropriate parameters (such as light output power) or give a prompt to instruct the operator to replace the filter component 11 of a suitable model.

[0116] In this embodiment, the skin color recognition component 34 is disposed on the outer periphery of the light-transmitting bracket 15. A head installation space Q3 is formed between the housing 12 and the light-transmitting bracket 15 (see Figure 5 ), the skin color recognition component 34 is accommodated in the head installation space Q3. The head installation space Q3 is a part of the internal space Q1 of the shell 12.

[0117] In this embodiment, the light-transmitting bracket 15 is located at the front of the skin treatment device 1000 near the front shell 21, and the front shell 21 at the front of the shell 12 needs to have a certain peripheral structure 85 to accommodate the light outlet K1 that cooperates with the light-transmitting bracket 15. In this way, the portion of the upper shell 19 or the lower shell 20 of the shell 12 close to the front shell 21 is offset outward by a certain distance relative to the light-transmitting bracket 15 at the light outlet K1 and the light-transmitting bracket 15, so that the above-mentioned head installation space Q3 is provided between the front of the shell 12 and the light-transmitting bracket 15.

[0118] This embodiment makes full use of the head installation space Q3 to arrange the skin color recognition component 34, and has a compact structure. The skin color recognition component 34 is arranged at the front of the skin treatment device 1000. It only needs to open a skin color recognition light opening K3 in the front shell 21, so that the skin color recognition component 34 can easily emit light forward and receive and process the skin reflected light, thereby realizing the skin color recognition function.

[0119] In this embodiment, the light emitting direction of the skin color recognition component 34 and the light emitting direction X of the processed light are both forward, so as to facilitate the real-time skin color recognition operation and avoid repeatedly switching the direction of the skin treatment device 1000 when skin color recognition and skin treatment need to be performed alternately.

[0120] In contrast, in some known technologies, the light emitting direction of the skin color recognition unit is not consistent with the processing light (such as being set at the rear of the device), which is obviously not convenient for real-time skin color recognition and the operation is more complicated.

[0121] Furthermore, in the skin treatment device 1000 of the present embodiment, the skin color recognition component 34 is disposed on the periphery of the light-transmitting bracket 15. Under the obstruction of the light-transmitting bracket 15, the treatment light for skin treatment passing through the light-transmitting member 26 will not or less illuminate the skin color recognition component 34, thereby reducing or avoiding the influence of the treatment light on the skin color recognition component 34.

[0122] Continue to see Figure 7-Figure 9In this embodiment, the skin color recognition component 34 includes a skin color recognition circuit board 35, a skin color recognition sensor 36 and a fill light 37. The skin color recognition sensor 36 and the fill light 37 are respectively arranged on the skin color recognition circuit board 35. The fill light 37 is used to emit recognition light. The reflected light obtained after the recognition light is reflected by the skin is received by the skin color recognition sensor 36, and the skin color can be recognized after being processed.

[0123] The skin color recognition sensor 36 may be, for example, a light intensity sensor. The light intensity of the reflected light after the recognition light is reflected by different skin colors is different. The skin color recognition sensor 36 recognizes the skin color by analyzing the light intensity information of the received reflected light.

[0124] In other embodiments, the skin color recognition sensor 36 may also be other types of optical sensors, which are not limited here.

[0125] The fill light 37 can be a common LED light, etc., which is not limited here.

[0126] In this embodiment, the skin color recognition circuit board 35 is fixedly connected to the outer periphery of the light-transmitting bracket 15. For example, the connection between the skin color recognition circuit board 35 and the light-transmitting bracket 15 is a snap connection, a threaded connection or an adhesive connection, which is not limited here.

[0127] In this embodiment, the skin color recognition circuit board 35 is connected to the light-transmitting bracket 15 by snapping. For example, the outer surface (defined as the third peripheral side surface P33) of the third peripheral side plate 30 (i.e., the cover plate 33) of the light-transmitting bracket 15 is provided with a first protrusion 38 and a second protrusion 39. The first protrusion 38 and the second protrusion 39 are spaced apart along the light-emitting direction X of the skin treatment device 1000, and a snap-fitting gap f2 is defined between the first protrusion 38 and the second protrusion 39. The skin color recognition circuit board 35 is fitted in the snap-fitting gap f2 with the board surface facing the light-emitting direction X. For example, the board surface of the skin color recognition circuit board 35 is perpendicular to the light-emitting direction X. The width of the snap-fitting gap f2 may be slightly greater than the thickness of the skin color recognition circuit board 35. The second protrusion 39 includes two second protrusions 40, and at least one of the second protrusions 40 is provided with a hook portion 41 at the end away from the third peripheral side surface P33, and the hook portion 41 abuts against the side of the skin color recognition circuit board 35 away from the third peripheral side surface P33, thereby reliably fixing the skin color recognition circuit board 35.

[0128] Optionally, the third peripheral side surface P33 is concave at a position corresponding to the clamping gap f2 to form a sunken groove C3, and the skin color recognition circuit board 35 is extended into the sunken groove C3 near the third peripheral side surface P33. By providing a concave sunken groove C3 to accommodate part of the skin color recognition circuit board 35, the height space occupied by the skin color recognition circuit board 35 can be reduced, making the structure more compact.

[0129] In this embodiment, the first convex portion 38 is located on the side of the skin color recognition circuit board 35 facing the light outlet K1 of the skin treatment device 1000; the first convex portion 38 includes two first convex blocks 42, and the skin color recognition sensor 36 and the fill light 37 are sandwiched between the two first convex blocks 42. By providing two spaced first convex blocks 42, the skin color recognition circuit board 35 can be more reliably limited, and the skin color recognition sensor 36 and the fill light 37 are sandwiched between the two first convex blocks 42. The two first convex blocks 42 can play a role in blocking light, reducing the influence of external light on the skin color recognition sensor 36 and the fill light 37, and can also reduce the light leakage of the fill light 37 to the outside.

[0130] The skin color recognition circuit board 35 can be electrically connected to the main control board 17 of the skin treatment device 1000 through a flexible printed circuit (FPC) to achieve signal transmission between the main control board 17 and the skin treatment device 1000.

[0131] See also Fig. 9 (See also Figure 5 ), in this embodiment, the shell 12 is provided with a skin color recognition light opening K3, which corresponds to the skin color recognition sensor 36 and the fill light 37 to allow the recognition light emitted by the fill light 37 to be emitted and the reflected light of the recognition light emitted by the fill light 37 after being reflected by the skin to be incident.

[0132] Optionally, the skin treatment device 1000 further includes a light shielding tube 43, which surrounds a skin color recognition light channel T4, with one end of the light shielding tube 43 surrounding the skin color recognition sensor 36 and the fill light 37, and the other end of the light shielding tube 43 being matched with the skin color recognition light opening K3. In this way, the influence of external light on the skin color recognition component 34 can be further reduced.

[0133] Optionally, the skin treatment device 1000 further includes a light guide 44, which includes an integrated light-transmitting cover plate 45 and a light-guiding column 46. The light-transmitting cover plate 45 covers the skin color recognition light opening K3, and the light-guiding column 46 cooperates with the skin color recognition light channel T4. The light-transmitting cover plate 45 covers the skin color recognition light opening K3 to achieve a sealed dustproof effect, and the light-guiding column 46 can achieve a light-guiding effect, which is beneficial for light to enter and exit the skin color recognition light channel T4.

[0134] In this embodiment, the filter assembly 11 is configured to be pluggable, so the skin treatment device 1000 can be used by inserting the filter assembly 11 or removing 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.

[0135] The skin treatment device 1000 in this embodiment also has a sensing function, which is used to sense whether the filter component 11 is plugged in place, and / or to sense and identify the model of the plugged filter component 11. To this end, in this embodiment, the filter component 11 is provided with a sensed portion 47, and the device body 10 is provided with a sensing component 48, and when the filter component 11 is plugged into the slot C2 of the light-transmitting bracket 15, the sensed portion 47 is sensed by the sensing component 48, thereby obtaining a sense signal or a model signal indicating that the filter component 11 is plugged in place.

[0136] These signals can be transmitted by the sensing component 48 to the main control board 17 via FPC or other means, and after being processed by the main control board 17, they are presented in a form that can be perceived by the user (such as images, sounds, vibrations, etc.).

[0137] For example, a visual display screen can be provided on the skin treatment device 1000, and when the main control board 17 receives a signal indicating that the filter component 11 is plugged in place, the background light of the display screen is turned green; when the main control board 17 receives a signal reflecting the model of the filter component 11, the corresponding model information (wavelength information of the filtered light) is presented in the form of text on the display screen.

[0138] For another example, before receiving the signal that the filter assembly 11 is plugged in, the main control board 17 controls the light output circuit to be disconnected, thereby preventing the skin treatment device 1000 from emitting light and avoiding misoperation.

[0139] See again Figure 7-Figure 9 In this embodiment, the sensing component 48 includes a sensing circuit board 49 and a trigger circuit 50 disposed on the sensing circuit board 49, and the trigger circuit 50 includes a trigger switch 51, and the trigger switch 51 is fixed to the sensing circuit board 49. The sensed portion 47 includes a trigger portion 52. When the filter component 11 is plugged in, the trigger switch 51 is triggered by the trigger portion 52, thereby giving a plug-in signal, indicating that the filter component 11 has been plugged in.

[0140] In this embodiment, the skin color recognition circuit board 35 is located at the third peripheral side P33, the sensing circuit board 49 includes a circuit board portion (defined as a first sensing circuit board 53) located at the outer side surface of the first peripheral side plate 28 (defined as the first peripheral side P31), and the trigger switch 51 is arranged on the first sensing circuit board 53.

[0141] The first sensing circuit board 53 and the skin color recognition circuit board 35 can be integrated into an integral circuit board to reduce the total number of circuit boards of the skin treatment device 1000. For example, in this embodiment, the skin color recognition circuit board 35 and the first sensing circuit board 53 are integrated into an L-shaped circuit board 54, and the board surface of the L-shaped circuit board 54 is perpendicular to the light emitting direction X.

[0142] Of course, in other embodiments, the sensing circuit board 49 and the skin color recognition circuit board 35 may be separately provided according to the structure, spatial arrangement or other needs, which is not limited here.

[0143] In order to accommodate the skin color recognition circuit board 35 and the first sensing circuit board 53 at the same time, the housing 12 and the cover plate 33 of the light-transmitting bracket 15 are spaced apart, and the housing 12 and the first peripheral side plate 28 of the light-transmitting bracket 15 are also spaced apart, that is, the head installation space Q3 (see Figure 5 ) includes the space on the third peripheral side P33 and the space on the first peripheral side P31.

[0144] In this embodiment, the L-shaped circuit board 54 can be located in front of the slot C2 along the light emitting direction X, so that the skin color recognition component 34 is closer to the side of the front shell 21 of the skin treatment device 1000. The trigger switch 51 is arranged on the board surface of the first sensing circuit board 53 behind the light emitting direction X, and the direction of the trigger switch 51 is the same as the direction of the plug-in port K2, and the trigger switch 51 and the slot C2 are staggered along the light emitting direction X. The trigger portion 52 of the filter component 11 includes a protruding portion 55 that protrudes from the filter component 11 to one side of the trigger switch 51 along the light emitting direction X, and the protruding portion 55 corresponds to the trigger switch 51 of the sensing component 48 along the plug-in direction Y1 of the filter component 11.

[0145] In this way, after the filter component 11 is inserted, if the filter component 11 is normally plugged into place, the protruding portion 55 as the sensed portion 47 will trigger the trigger switch 51 of the sensing component 48, thereby being sensed by the trigger switch 51 and obtaining a plug-in signal; if the filter component 11 is not plugged into place, no plug-in signal will be obtained.

[0146] Therefore, the skin treatment device 1000 can conveniently identify whether the filter assembly 11 is plugged in place, ensuring safe use.

[0147] In addition, the skin treatment device 1000 in this embodiment corresponds to the trigger switch 51 along the plug-in direction Y1 through the laterally protruding protrusion 55, so that after the filter component 11 is inserted, the sensed portion 47 can press against the sensing component 48 along the plug-in direction Y1, and the two will not wear each other.

[0148] In this embodiment, optionally, the skin treatment device 1000 further includes an abutment member 56. The abutment member 56 is disposed between the protruding portion 55 and the trigger switch 51, and is used to transmit the force of the protruding portion 55 to the trigger switch 51. The switch stroke of the trigger switch 51 is along the plugging and unplugging direction Y1 of the filter assembly 11, and the abutment member 56 is movably connected to the side of the trigger switch 51 facing the protruding portion 55.

[0149] See also Fig.10 , Fig.11 and Fig.12In this embodiment, the sensing circuit board 49 further includes a second sensing circuit board 57. The sensing component 48 further includes a filter model identification circuit 60 disposed on the second sensing circuit board 57. The filter model identification circuit 60 includes a plurality of conductive probes 58, and the plurality of conductive probes 58 are respectively used as detection points of the filter model identification circuit 60. The sensed portion 47 includes a conductive portion 59, and the conductive portion 59 corresponds to part or all of the plurality of conductive probes 58, and the conductive portions 59 of the filter components 11 of different models are configured to be able to conduct different combinations of conductive probes 58.

[0150] In this embodiment, the second sensing circuit board 57 is located at the second peripheral side plate 29, and the conductive portion 59 is disposed at the rear end of the filter assembly 11 (i.e., the end of the filter assembly 11 away from the plug-in port K2). When the filter assembly 11 is inserted into place, the conductive portion 59 can abut against at least part of the conductive probe 58, so that the contacted conductive probe 58 is electrically conductive, and thus is recognized by the filter model recognition circuit 60.

[0151] In this embodiment, the second sensing circuit board 57 and the skin color recognition circuit board 35 (see Fig. 9 In other embodiments, the second sensing circuit board 57 may also be integrated with the skin color recognition circuit board 35.

[0152] In this embodiment, the second sensing circuit board 57 is attached and fixed to the outer surface (defined as the second peripheral side surface P32) of the second peripheral side plate 29 with the board surface facing the rear end of the filter assembly 11. The second sensing circuit board 57 and the second peripheral side plate 29 can be bonded, threaded or clamped, which is not limited here.

[0153] Optionally, the second peripheral side plate 29 is provided with a plurality of probe vias K9 that penetrate along the plug-in direction Y1. In this embodiment, the conductive probe 58 is a conductive probe 61 (such as a conductive spring pin), one end of the conductive probe 61 is fixed to the sensing circuit board 49, and the other end vertically extends out of the sensing circuit board 49, that is, the conductive probe 61 extends along the plug-in direction Y1. The plurality of conductive probes 61 extend into the slot C2 through the plurality of probe vias K9 respectively, so that the conductive portion 59 at the rear end of the filter component 11 inserted into the slot C2 can abut against the conductive probe 58 along the plug-in direction Y1 of the filter component 11. Therefore, in this embodiment, the conductive portion 59 as the sensed portion 47 and the conductive probe 61 as part of the sensing component 48 are opposite to each other along the plug-in direction Y1.

[0154] In this embodiment, when the filter assembly 11 is inserted along the plug-in direction Y1, the conductive portion 59 of the sensed portion 47 abuts against the conductive probe 61 of the sensing assembly 48 along the plug-in direction Y1, thereby realizing the identification of the model of the filter assembly 11. The insertion process of the filter assembly 11 will not cause relative friction with the conductive probe 61 of the sensing assembly 48, thereby avoiding friction loss. In some known technologies, when the filter assembly 11 is inserted, the lateral surface of the filter assembly 11 is contacted by a lateral spring sheet. In this technology, during the insertion process of the filter assembly 11, the side surface of the filter assembly 11 will rub against the spring sheet, and there may be a certain amount of friction loss after long-term use, which may affect the electrical contact and identification functions.

[0155] See also Fig.11 and Fig.12 The filter assembly 11 provided in this embodiment includes a filter mounting frame 62, a filter 63 and the aforementioned conductive portion 59. The filter 63 is mounted on the filter mounting frame 62. An end of the filter mounting frame 62 away from the plug-in port K2 along the plug-in direction Y1 is provided with a mounting groove C4 formed inwardly, and the conductive portion 59 is mounted in the mounting groove C4.

[0156] In this embodiment, the conductive portion 59 has a clearance W1, and the setting position of the clearance W1 of the conductive portion 59 of the filter assembly 11 is in a one-to-one correspondence with the model of the filter assembly 11. The conductive portions 59 of filter assemblies 11 of different models have different clearance W1, so that different conductive probes 58 can be turned on, and the conductive probes 58 corresponding to the clearance W1 will not be turned on by the conductive portion 59. Therefore, the filter model identification circuit 60 has certain differences, so that the filter assemblies 11 of different models can be distinguished.

[0157] For example Fig.11 As shown in FIG. 1 , there are three conductive probes 61, and the three conductive probes 61 are arranged in a row along the width direction of the filter assembly 11. Correspondingly, the conductive portion 59 is a conductive block, which has a clearance W1 and corresponds to Fig.11 The rightmost conductive probe 61. Thus, when the filter assembly 11 having the conductive portion 59 is inserted into the slot C2, Fig.11 The two conductive probes 61 on the left are turned on, and Fig.11 The rightmost conductive probe 61 is not turned on.

[0158] Fig.13 Shown with Fig.11 Another filter component 11 having a different model of the filter component 11. Fig.13 The filter assembly 11 in the filter 63 is the same as the model Fig.11 In addition to the difference in the filter components 11 (reflected in the difference in the filter bands), Fig.13 The conductive portion 59-1 of the filter assembly 11 is also connected to Fig.11The conductive part 59 is different. Specifically, Fig.13 The conductive portion 59-1 has two avoidance positions W1, and the two avoidance positions W1 correspond to the two conductive probes 61 on the right side. Fig.13 When the filter assembly 11 is inserted into the slot C2, only the conductive probe 61 on the left side is in conductive contact with the conductive portion 59-1.

[0159] In this way, when different types of filter components 11 are inserted, the filter model identification circuit 60 has different conduction modes, so that the type of filter component 11 inserted can be distinguished by the difference in voltage / resistance and other values ​​at some positions in the filter model identification circuit 60.

[0160] See also Fig.14 (See also Fig.11 ), in this embodiment, the filter mounting frame 62 includes a main frame 64 and a holding head 65, and the mounting slot C4 is provided in the main frame 64. The main frame 64 is provided with a light transmission area S1 and a filter slot C5, and the filter 63 is matched with the filter slot C5 and covers the light transmission area S1; the entrance of the filter slot C5 is located at the end of the main frame 64 away from the mounting slot C4, and the holding head 65 is plugged and matched with one end of the entrance of the filter slot C5 and abuts against the filter 63.

[0161] When installing or replacing the filter 63, the filter assembly 11 can be loaded into the filter slot C5, and then the holding head 65 can be loaded to position the filter 63, so that the filter 63 can be easily disassembled. The conductive part 59 can be configured to be detachably connected to the mounting slot C4, so that when replacing a filter 63 of a different model, the corresponding conductive part 59 can be replaced to ensure that the model of the filter assembly 11 is correctly identified.

[0162] In this embodiment, the holding head 65 includes a plug section 103 and a protruding section 67. The plug section 103 is in the form of a sheet and is inserted into the entrance end of the filter slot C5. The protruding section 67 is connected to the plug section 103 and extends to the side of the plug section 103 to contact the trigger switch 51 (see Figure 8 )'s protrusion 55.

[0163] In this embodiment, a snap-in protrusion 68 is provided on the surface of the plug-in section 103, and a snap-in fitting hole K5 is provided at one end of the main film frame 64 close to the holding head 65. When the plug-in section 103 is plugged into the main film frame 64, the snap-in protrusion 68 is snap-fitted into the snap-fitting hole K5 to achieve snap-in fixation.

[0164] In this embodiment, the main film frame 64 optionally includes an inserting portion 69 and a convex edge 70. The inserting portion 69 is used to carry the filter 63 and is inserted into the slot C2. The convex edge 70 is formed by protruding from one end of the inserting portion 69 close to the holding head 65 toward the outside of the filter slot C5. When the holding head 65 is inserted into the main film frame 64, the protruding section 67 overlaps with the convex edge 70 (see Fig.11 ), the protruding section 67 abuts against the trigger switch 51 through the convex edge 70. The overlapping convex edge 70 and the protruding section 67 have a large thickness, thereby having a large structural rigidity, which is conducive to reliably pressing against the trigger switch 51 and maintaining a controllable deformation amount.

[0165] The filter assembly 11 provided in this embodiment, when inserted into the slot C2, can press the trigger switch 51 through the protruding section 67 and the protruding edge 70, and can also realize model identification of the filter assembly 11 through the conductive part 59 contacting the conductive probe 58. It has a reasonable structure and is easy to use.

[0166] See also Figure 15-18 The skin treatment device 1000 in this embodiment also includes a flexible shielding member 71, which can block the entrance of the slot C2 when the filter component 11 is not inserted, thereby preventing dust and light leakage; and when the filter component 11 is inserted, the flexible shielding member 71 can avoid the filter component 11 and will not block the filter component 11 from entering the slot C2.

[0167] In this embodiment, the slot C2 is provided with a concave escape space Q4 at its entrance. Optionally, the light-transmitting bracket 15 includes a first clamping wall 76 and a second clamping wall 77 spaced along the thickness direction of the filter assembly 11 (in this embodiment, the thickness direction of the filter assembly 11 is parallel to the light emitting direction X), the slot C2 is located between the first clamping wall 76 and the second clamping wall 77, and the escape space Q4 is formed by the concave surface of the second clamping wall 77 toward one side of the first clamping wall 76. The first clamping wall 76 is vertically connected to the outer periphery of the first peripheral side plate 28, and the second clamping wall 77 is connected to the first clamping wall 76. The first clamping wall 76 and the second clamping wall 77 are respectively connected to the fourth peripheral side plate 31 at one end close to the fourth peripheral side plate 31. The first clamping wall 76 and the second clamping wall 77 are connected to one end of the third peripheral side plate 30 (i.e., the cover plate 33) through a connecting wall, so that the entrance of the slot C2 is defined by the closed ring formed by the first clamping wall 76, the fourth peripheral side plate 31, the second clamping wall 77 and the connecting arm connected end to end, thereby improving the structural stability at the entrance of the slot C2 and facilitating the insertion of the filter assembly 11. Optionally, the light-transmitting bracket 15 further includes a third clamping wall 78, which is located on the side of the second clamping wall 77 away from the first clamping wall 76, and the clamping groove C6 is defined between the third clamping wall 78 and the second clamping wall 77.

[0168] The flexible shielding member 71 includes a connecting portion 72 and a flexible shielding sheet 73. The connecting portion 72 is connected to the device body 10 at the entrance of the slot C2 near the avoidance space Q4. One side of the flexible shielding sheet 73 is connected to the connecting portion 72, and the other side extends from the connecting portion 72 to shield the entrance of the slot C2 (see FIG. Fig.17 ) or when the filter assembly 11 is inserted, it is pushed by the filter assembly 11 to be accommodated in the avoidance space Q4 (see Fig.18 ).

[0169] The connection portion 72 may be connected to one side of the second clamping wall 77 , for example, the connection portion 72 is inserted into and fits into a clamping groove C6 between the second clamping wall 77 and the third clamping wall 78 .

[0170] The flexible baffle 73 extends from one side of the first clamping wall 76 to one side of the second clamping wall 77 to block the entrance of the slot C2. Optionally, the flexible baffle 73 includes a connected support section 74 and a blocking section 75, the support section 74 is supported on the second clamping wall 77 along the insertion direction of the filter assembly 11, the blocking section 75 corresponds to the entrance of the slot C2, and the blocking section 75 can be bent relative to the support section 74 to be accommodated in the avoidance space Q4. Among them, the side surface of the flexible baffle 73 facing the slot C2 is concave to form a fold groove C9 corresponding to the position of the avoidance space Q4, and the support section 74 and the blocking section 75 are located on both sides of the fold groove C9. By providing the fold groove C9, when the filter assembly 11 is inserted, the blocking section 75 of the flexible baffle 73 can be more easily bent along the fold groove C9 to enter the avoidance space Q4 to avoid the filter assembly 11, and the resistance to the insertion of the filter assembly 11 is smaller, thereby improving the user experience.

[0171] The flexible shielding member 71 in this embodiment can be integrally formed of a silicone material, and its connecting portion 72 can be installed in the clamping groove C6 by bonding or interference fit.

[0172] See also Fig.19 In another embodiment, there are two avoidance spaces Q4, and the two avoidance spaces Q4 are respectively located on both sides of the entrance of the slot C2. Correspondingly, there are two flexible shielding members 71, and the connecting parts 72 of the two flexible shielding members 71 are respectively connected to the device body 10 on both sides of the entrance of the slot C2 near the avoidance spaces Q4. The flexible baffles 73 of the two flexible shielding members 71 extend toward each other and jointly block the entrance of the slot C2, or are pushed by the filter assembly 11 to be respectively accommodated in the two avoidance spaces Q4 when the filter assembly 11 is inserted. In this embodiment, the flexible baffles 73 of the two flexible shielding members 71 can abut against each other to completely close the entrance of the slot C2; they can also have a certain overlapping part to improve the dust and light blocking effect.

[0173] In the skin treatment device 1000 of this embodiment, when the filter component 11 is not inserted, the flexible baffle 73 blocks the entrance of the slot C2, which can prevent dust and light leakage; when the filter component 11 is inserted, the filter component 11 can push the flexible baffle 73 to be accommodated in the avoidance space Q4.

[0174] Therefore, the skin treatment device 1000 of this embodiment is easy to use and can keep the slot C2 covered when the filter assembly 11 is pulled out, thus having better dust and light leakage prevention effects.

[0175] However, in some known skin treatment devices, when the filter assembly 11 is pulled out, the entrance of the slot C2 cannot be sealed, and dust is easily introduced, and light in the treatment device may also leak out from the entrance of the slot C2.

[0176] See also Figure 5 and Figure 20-Figure 29 In this embodiment, the skin treatment device 1000 may further be provided with a heat dissipation system 16 as required. The heat dissipation system 16 may realize overall heat dissipation or local heat dissipation of the skin treatment device 1000 to reduce the overall temperature or local temperature of the skin treatment device 1000.

[0177] The heat dissipation system 16 may adopt air cooling, liquid cooling or other cooling forms, which are not limited here.

[0178] For example, the heat dissipation system 16 of this embodiment can be used to cool the light-transmitting member 26 , so that the light-transmitting member 26 can be kept at a relatively low temperature to maintain a better icing effect.

[0179] The heat dissipation system 16 of this embodiment can be used to dissipate heat at the light source 22 (such as the lamp tube 23). The lamp tube 23 generates a lot of heat during the light emission process. By dissipating heat at this place, it is possible to prevent the light source 22 and / or components near the light source 22 (such as the light source bracket 14, etc.) from being heated by the light source 22 or irradiated by the light source 22, thereby preventing them from being deformed by high temperature and affecting structural performance or other physical properties.

[0180] The heat dissipation system 16 of this embodiment can also transfer the heat inside the shell 12 to the outside by increasing the air flow speed inside and outside the shell 12 to achieve overall heat dissipation.

[0181] See also Figure 5 The light-transmitting member 26 itself can dissipate heat through the cooling sheet 95 and the heat sink assembly 92 disposed in the housing 12, that is, the cooling sheet 95 and the light-transmitting member 26 constitute a cold compress assembly for cold compressing the skin to achieve the effect of freezing point hair removal. Of course, in other embodiments, the cold compress assembly can also be disposed on the periphery or side of the light-transmitting member 26 and the light outlet K1 to provide cold compress on the periphery of the light.

[0182] See also Fig. 20 and Fig.21 In this embodiment, the light source bracket 14 includes a front frame section 79 and a rear frame section 80, and the rear frame section 80 is connected to the rear of the front frame section 79. In this embodiment, the front of the light emitting direction X of the skin treatment device 1000 is referred to as the "front", and the rear of the light emitting direction X of the skin treatment device 1000 is referred to as the "rear".

[0183] The rear frame section 80 is connected with a connecting column 84 for supporting and connecting to the housing 12 or other structures. For example, the connecting column 84 abuts against the inner surface of the housing 12, and the housing 12 and the light source bracket 14 are relatively fixed by screws (not shown) screwed in from the outside of the housing 12 to the connecting column 84.

[0184] The front frame section 79 of the light source bracket 14 includes a bottom wall 81, two side walls 82 and two end walls 83. The two side walls 82 are respectively connected to the two sides of the bottom wall 81. The two end walls 83 are respectively connected to the other two sides of the bottom wall 81 and are located at the two ends of the length direction Y2 of the lamp tube. The length direction Y2 of the lamp tube refers to the extension direction of the axis of the lamp tube 23. In this embodiment, the length direction Y2 of the lamp tube is parallel to the plug-in direction Y1 of the filter assembly 11. The bottom wall 81, the two side walls 82 and the two end walls 83 together enclose a mounting cavity Q2 that opens toward the light emitting direction X of the skin treatment device 1000.

[0185] In the present embodiment, a side wall 82 of the light source bracket 14 is provided with an air inlet vent K31 and an air outlet vent K32 at both ends along the length direction Y2 of the lamp tube. The air inlet vent K31 and the air outlet vent K32 are respectively connected to the two ends of the installation cavity Q2 along the length direction Y2 of the lamp tube to form an air inlet channel T11 and an air outlet channel T12. The air inlet channel T11 and the air outlet channel T12 are spaced apart along the length direction Y2 of the lamp tube.

[0186] The air inlet K31 can be directly or indirectly connected to the air outlet K52 of the fan 91 (see Fig.24 and Fig.25 ), the air outlet K32 can be directly or indirectly connected to the air outlet K22 on the housing 12 (see Fig.24 and Fig.25 In this way, when the fan 91 is running, a cooling airflow can be blown in from the air inlet duct K31, and the cooling airflow flows in from the air inlet channel T11, passes through the first airflow channel T21 and the second airflow channel T22 to take away the heat, and then flows out of the mounting cavity Q2 of the light source bracket 14 from the air outlet duct K32 through the air outlet channel T12, and flows out of the shell 12 through the air outlet K22 of the shell 12.

[0187] See again Fig. 20 and Fig.21In this embodiment, the reflective cup 24 includes a main cup body 86 and two fixed legs 87. The main cup body 86 is mainly used to reflect the light emitted by the lamp tube 23 forward along the light emitting direction X, and the fixed legs 87 are used to install and fix the reflective cup 24.

[0188] In this embodiment, the main cup body 86 is illustratively an arc-shaped sheet structure extending along the length direction Y2 of the lamp tube, and its cross section in a plane perpendicular to the length direction Y2 of the lamp tube is roughly C-shaped. The inner side surface of the main cup body 86 (i.e., the surface on the side close to the front of the light emitting direction X) is a reflective surface P1. Two fixed legs 87 are respectively connected to the two ends of the main cup body 86 along the length direction Y2 of the lamp tube, and extend toward the side of the bottom wall 81 close to the light source bracket 14.

[0189] See also Fig. 22 and Fig.23 In this embodiment, the reflective cup 24 is installed on the light source bracket 14. For example, the two sides of the opening of the main cup body 86 respectively abut the two side walls 82 of the light source bracket 14, and the middle part of the main cup body 86 is concave into a C shape relative to the two sides of the reflective cup 24 toward the side close to the bottom wall 81, and the middle part of the reflective cup 24 and the bottom wall 81 are spaced apart but not in contact, so that a first air flow channel T21 is formed between the reflective cup 24 and the bottom wall 81. The concave shape of the C-shaped main cup body 86 enables the main cup body 86 to have a second air flow channel T22 on the side away from the first air flow channel T21. In this embodiment, the first air flow channel T21 and the second air flow channel T22 extend along the length direction Y2 of the lamp tube respectively, the first air flow channel T21 is connected between the air inlet channel T11 and the air outlet channel T12, and the second air flow channel T22 is connected between the air inlet channel T11 and the air outlet channel T12. Combined with Figure 5 As shown, for the embodiment in which the optical filter 63 is provided, the second air flow channel T22 is located between the reflective cup 24 and the optical filter 63. In this embodiment, one end of the light-transmitting bracket 15 is connected to the light source bracket 14, and the other end is connected to the position of the housing 12 near the light outlet K1. The light-transmitting member 26 and the optical filter 63 are respectively mounted on the light-transmitting bracket 15, and the second air flow channel T22 is surrounded by the light-transmitting bracket 15, the reflective cup 24 and the optical filter 63. In some embodiments, if there are other optical elements (such as a pluggable filter assembly 11) plugged between the optical filter 63 and the light source bracket 14, the second air flow channel T22 may also be located between the optical element and the reflective cup 24.

[0190] In this embodiment, the edges of the opening of the main cup body 86 (i.e. Fig. 20 The abutment between the upper and lower parts of the opening of the middle main cup body 86 and the two side walls 82 of the light source bracket 14 can be a completely fitted sealed abutment, or there can be a small gap, which is not limited here.

[0191] The reflective cup 24 is supported and connected to the bottom wall 81 of the light source bracket 14 through its two fixed legs 87. The specific connection method can be set as needed, for example, the fixed legs 87 pass through the bottom wall 81 of the light source bracket 14 and then bend and fix on the side surface of the bottom wall 81 away from the reflective cup 24.

[0192] In this embodiment, the reflective cup 24 is provided with an air hole K8 , and the air hole K8 is connected to the first air flow channel T21 and the second air flow channel T22 .

[0193] The skin treatment device 1000 of this embodiment, by providing the air hole K8 on the reflective cup 24, can make the airflows of the first airflow channel T21 and the second airflow channel T22 on both sides of the reflective cup 24 exchange with each other, so that part of the heat flow in the second airflow channel T22 can enter the first airflow channel T21 and be carried away by the airflow of the first airflow channel T21, thereby improving the heat dissipation efficiency.

[0194] In contrast, in some related technologies, the reflective cup 24 is arranged to fit the bottom wall 81, and the aforementioned first airflow channel T21 cannot be formed. The airflow entering the reflective cup 24 mainly flows on the inner side of the reflective cup 24 (the side away from the bottom wall 81). With this arrangement of the reflective cup 24, the heat dissipation effect of the airflow on the reflective cup 24 and the surrounding area is poor.

[0195] Continue to see Fig. 22 and Fig.23 In this embodiment, the connection between the side wall 82 and the bottom wall 81 is an angled transition, and the corner is dug out to form a larger space, which is beneficial to increase the cross-sectional area of ​​the first airflow channel T21 and improve the airflow heat dissipation efficiency.

[0196] Optionally, at least one side wall 82 is provided with a concave notch C1, and the bottom surface of the notch C1 is spaced from the reflective cup 24. Fig.23 A concave notch C1 is provided at the lower side wall 82 . The concave notch C1 increases the cross-sectional area of ​​the first airflow channel T21 and reduces the contact area between the side wall 82 and the reflective cup 24 , which is beneficial to improving the heat dissipation efficiency.

[0197] See again Fig. 20 and Fig.21 The lamp tube 23 is generally in a long tubular structure, and can be a lamp tube 23 based on various light-emitting principles, such as an LED lamp tube 23, an IPL lamp tube 23, a laser lamp tube 23, etc., which are not limited here. The lamp tube 23 is located on the side of the reflector cup 24 away from the light source bracket 14, and the middle part of the lamp tube 23 in the long direction is located in the second air flow channel T22, and the two ends of the lamp tube 23 in the long direction are electrodes 89 for realizing the electrical connection of the lamp tube 23.

[0198] See again Fig. 20and Fig.21 In this embodiment, the skin treatment device 1000 further includes two light shielding parts 90, which are respectively located at the two ends of the reflective cup 24 along the length direction Y2 of the lamp tube. One of the two light shielding parts 90 is located between the second airflow channel T22 and the air inlet channel T11, and the second airflow channel T22 and the air inlet channel T11 are connected through the gap f1 corresponding to the light shielding part 90; the other of the two light shielding parts 90 is located between the second airflow channel T22 and the air outlet channel T12, and the second airflow channel T22 and the air outlet channel T12 are connected through the gap f1 corresponding to the light shielding part 90. The setting of the light shielding part 90 can achieve light shielding of the lamp tube 23 and reduce the leakage of light emitted by the lamp tube 23. The light shielding part 90 is provided with a through hole K4, and the two ends of the lamp tube 23 in the length direction pass through the through holes K4 of the two light shielding parts 90 respectively, and the aforementioned gap f1 is formed between the lamp tube 23 and the through hole K4. Through the gap f1, the airflow entering from the air inlet channel T11 can enter the second airflow channel T22 through the gap f1 on one side, and then flow out to the air outlet channel T12 through the gap f1 on the other side. That is, the setting of the light shielding portion 90 has both light shielding and air flow effects.

[0199] Due to the shading portion 90, it has a certain blocking effect on the airflow flowing into and out of the second airflow channel T22. By opening the air hole K8 to connect the first airflow channel T21 and the second airflow channel T22, the airflow between the first airflow channel T21 and the second airflow channel T22 can be exchanged, thereby reducing the adverse effects of the shading portion 90 and ensuring the heat dissipation efficiency.

[0200] It should be noted that the shading portion 90 is mainly arranged on the side of the reflective cup 24 away from the light source bracket 14, and does not block the connection between the first airflow channel T21 and the air inlet channel T11 or the air outlet channel T12, that is, the shading portion 90 will not prevent the airflow from the air inlet channel T11 from entering the first airflow channel T21, nor will it prevent the airflow from flowing out of the first airflow channel T21 to the air outlet channel T12.

[0201] It should be noted that, compared with the solution without the shading portion 90, the shading portions 90 are added at the left and right ends of the reflective cup 24, which can effectively reduce the light leakage of the lamp 23 from the two ends of the reflective cup 24, thereby effectively reducing the plug-in port K2 on the housing 12 (see Figure 2 ) to avoid light leakage to avoid discomfort to users.

[0202] However, by adding the shading parts 90 at the left and right ends of the reflective cup 24 to reduce the amount of light leakage, the two ends of the first airflow channel T21 defined by the reflective cup 24 will be blocked to a certain extent, so that the airflow can only flow into or out of the first airflow channel T21 of the reflective cup 24 through the gap f1, thereby reducing the amount of air flowing in the reflective cup 24 and reducing the heat dissipation efficiency. For this reason, an air hole K8 is added at the bottom of the reflective cup 24 so that the airflow inside and outside the reflective cup 24 (i.e., the airflow of the first airflow channel T21 and the airflow of the second airflow channel T22) can be exchanged, so that the high temperature in the first airflow channel T21 can be transferred to the low temperature gas in the second airflow channel T22, so that it can be carried out by the airflow in the second airflow channel T22, thereby improving the heat dissipation efficiency, so as to effectively ensure or improve the heat dissipation efficiency of the reflective cup 24 with the shading part 90.

[0203] See also Fig.24 or Fig.25 In this embodiment, the housing 12 is further provided with an air inlet K21 and an air outlet K22, and the air inlet K21 and the air outlet K22 are connected to the internal space Q1 respectively. The air inlet K21 and the air outlet K22 can be arranged at different positions of the housing 12 to reduce the mutual influence between the air inlet and the air outlet. The air inlet K21 and the air outlet K22 are used for gas to flow into and out of the internal space Q1 respectively to achieve heat dissipation of the skin treatment device 1000. The heat dissipation system 16 can realize or accelerate the above-mentioned air flow exchange to achieve the desired heat dissipation effect. The air inlet K21 and the air outlet K22 can be set at different positions of the lower shell 20.

[0204] Continue to see Fig.24 or Fig.25 In this embodiment, the heat dissipation system 16 of the skin treatment device 1000 further includes a fan 91, which is installed in the internal space Q1 of the housing 12 (see Figure 5 The fan 91 has an air intake port K51 and an air outlet K52. When the fan 91 is working, air with a relatively low temperature in the environment enters the internal space Q1 of the housing 12 from the air inlet K21, is sucked into the fan 91 through the air intake port K51, blown out from the air outlet K52, and passes through the heat dissipation channel (such as the first airflow channel T21 and the second airflow channel T22) inside the skin treatment device 1000 to take away the heat, and then is discharged to the external environment from the air outlet K22 of the housing 12, thereby dissipating heat and cooling the skin treatment device 1000.

[0205] Continue to see Fig.24 or Fig.25 In this embodiment, the skin treatment device 1000 further includes a heat sink assembly 92. The heat sink assembly 92 includes a heat sink frame 93 and a plurality of heat sinks 94 mounted on the heat sink frame 93, and adjacent heat sinks 94 are spaced apart from each other.

[0206] Optionally, the heat sink frame 93 is connected to the side wall 82 on the side where the air inlet K31 and the air outlet K32 of the light source bracket 14 are provided, and together with the air inlet K31 of the light source bracket 14, forms a passage corresponding to the air outlet K52 of the fan 91. The heat sink frame 93 is also provided with an air flow outlet K7 connected to the air outlet K32.

[0207] The fan 91 is connected to the light source bracket 14, and a part of the air outlet K52 of the fan 91 corresponds to the heat sink 94 to dissipate heat from the heat sink 94; another part of the air outlet K52 corresponds to the air inlet K31 of the light source bracket 14, which is used to provide airflow through the first airflow channel T21 and the second airflow channel T22. The airflow will flow out from the airflow outlet K7 after passing through the air inlet channel T11, the first airflow channel T21, the second airflow channel T22, and the air outlet channel T12, and finally be discharged into the environment from the air outlet K22 of the housing 12. In this process, part of the airflow in the second airflow channel T22 can also enter the first airflow channel T21 through the air hole K8, and flow downstream from the first airflow channel T21.

[0208] In this embodiment, the air hole K8 on the reflective cup 24 is used to connect the first air flow channel T21 with the second air flow channel T22. The specific shape of the air hole K8 can be set as needed.

[0209] For example Fig. 22 As shown in the figure, the air holes K8 extend along the length direction Y2 of the lamp tube, and are continuous long strip holes along the length direction Y2 of the lamp tube. Optionally, the length of the distribution area of ​​the air holes K8 (i.e., the size of the long strip holes along the length direction Y2 of the lamp tube) is 10 to 50 mm, and can be 15 to 36 mm, such as 16, 17, 18, 19, 20, 21, 22, 23, 24, 25, 26, 27, 28, 29, 30, 31, 32, 32.5, 33, 34 or 35 mm, etc. Optionally, the width of the distribution area of ​​the air holes K8 (i.e., the length of the air holes K8 in the circumferential direction of the reflective cup 24) is 0.5 to 5.0 mm, and can be 1.0 to 4 mm, such as 1.2, 1.3, 1.4, 1.5, 1.6, 1.7, 1.8, 1.9, 2.0, 2.1, 2.2, 2.3, 2.4, 2.5, 2.6, 2.7, 2.8, 2.9, 3.0, 3.1, 3.2, 3.3, 3.4, 3.5, 3.6, 3.7, 3.8, or 3.9 mm, etc. Through this size design, it is possible to ensure a good ventilation effect, and the light generated by the lamp tube 23 will not leak too much from the air holes K8.

[0210] See also Fig. 22 and Fig.23In this embodiment, the air hole K8 is located on the side of the lamp tube 23 opposite to the light emitting direction X of the skin treatment device 1000, that is, the air hole K8 is located at the rear side of the lamp tube 23. In this way, a large light loss caused by opening the air hole K8 in front of the light emitting direction X of the lamp tube 23 can be avoided.

[0211] In this embodiment, the air hole K8 is optionally located at the side of the lamp tube 23 away from the light outlet K1 (see Figure 5 ) and is arranged corresponding to the lamp tube 23. Tests show that the area of ​​the reflector cup 24 corresponding to the lamp tube 23 on the side of the lamp tube 23 away from the light outlet K1 belongs to the blind area of ​​the lamp tube 23, and the light irradiated on the lamp tube 23 in these areas is difficult to be reflected by the reflector cup 24 and emitted from the light outlet K1, but will at least partially be reflected again to the lamp tube 23 and absorbed by the lamp tube 23. Therefore, the air hole K8 opened at this position can realize the function of airflow passing, and has little effect on the reflection efficiency of the reflector cup 24.

[0212] Of course, in other embodiments, the air hole K8 may also be disposed at other positions of the reflective cup 24 , and it is sufficient to connect the first air flow channel T21 and the second air flow channel T22 to achieve the air flow effect.

[0213] In this embodiment, optionally, the projection of the air hole K8 in the plane perpendicular to the light emitting direction X is located within the projection range of the lamp tube 23 in the plane perpendicular to the light emitting direction X. In this way, it is possible to limit the portion of the reflective cup 24 outside the shielding range of the lamp tube 23 from being cut off as the air hole K8 and to reduce the reflective ability of the reflective cup 24.

[0214] In other embodiments, the air hole K8 may also be set larger to exceed the projection range of the lamp tube 23 according to air flow and heat dissipation requirements, which is not limited here.

[0215] In this embodiment, optionally, see Fig.23 The edge of the air hole K8 is folded toward the side away from the lamp tube 23 to form a folded edge 88. By providing the folded edge 88, the structural rigidity of the reflective cup 24 can be increased to compensate for the loss of structural rigidity of the reflective cup 24 caused by the opening of the air hole K8.

[0216] Fig.26Another embodiment is shown, in which the reflective cup 24 has a vent K8 including a plurality of through holes K6 arranged in sequence along the length direction Y2 of the lamp tube, and the through holes K6 may be small holes of circular, square or other shapes, and the through holes K6 are arranged in a row along the length direction Y2 of the lamp tube. The length of the distribution area of ​​the vent K8 (i.e., the length of the ventilation area formed by all the through holes K6 in the circumferential direction of the reflective cup 24) is 10 to 50 mm, and may be 15 to 36 mm, such as 16, 17, 18, 19, 20, 21, 22, 23, 24, 25, 26, 27, 28, 29, 30, 31, 32, 32.5, 33, 34 or 35 mm, etc. Optionally, the width of the distribution area of ​​the air holes K8 (i.e., the length of the ventilation area formed by all the multiple through holes K6 in the length direction of the lamp tube 23) is 0.5 to 5.0 mm, and can be optionally 1.0 to 4 mm, such as 1.2, 1.3, 1.4, 1.5, 1.6, 1.7, 1.8, 1.9, 2.0, 2.1, 2.2, 2.3, 2.4, 2.5, 2.6, 2.7, 2.8, 2.9, 3.0, 3.1, 3.2, 3.3, 3.4, 3.5, 3.6, 3.7, 3.8, or 3.9 mm, etc.

[0217] And the area of ​​a single through hole K6 is greater than or equal to 2 square millimeters. Of course, in other embodiments, the air holes K8 can also be arranged in other forms, such as arranged in two rows or even more rows. Through this size design, it can ensure that the air flow effect is good, and the light generated by the lamp tube 23 will not leak too much from the air holes K8.

[0218] See also Fig. 27 and Fig.28 In another implementation of this embodiment, Fig.23 Compared with the embodiment shown in the figure, the skin treatment device 1000 further includes a reflector 96. The reflector 96 is located in the first airflow channel T21, and the reflector 96 has a reflective surface P2 arranged corresponding to the air hole K8, and the reflective surface P2 faces the air hole K8. By arranging the reflector 96, part or all of the light emitted by the lamp tube 23 that passes through the air hole K8 can be reflected back through the air hole K8, and at least part of the reflected light can be emitted from the light outlet K1 for skin treatment, so that the amount of the useful part of the light emitted by the lamp tube 23 can be increased, and the light emitting efficiency of the lamp tube 23 can be improved.

[0219] Optionally, the reflector 96 is attached to the inner wall of the first airflow channel T21 (i.e., the surface of the bottom wall 81 of the light source bracket 14). The reflector 96 of this structure is convenient to set, and it is easy to use the bottom wall 81 of the light source bracket 14 to keep its reflective surface P2 flat. In addition, the reflector 96 of this structure has little effect on the airflow in the first airflow channel T21.

[0220] Optionally, the projection of the air hole K8 in a plane perpendicular to the light emitting direction X of the skin treatment device 1000 is located within the projection range of the reflector 96 in a plane perpendicular to the light emitting direction X. In this way, the light of the lamp tube 23 passing through the air hole K8 can be irradiated more on the reflector 96, which is beneficial for the reflector 96 to re-reflect more light through the air hole K8, thereby improving the luminous efficiency of the lamp tube 23.

[0221] Fig.29 In the illustrated embodiment, the reflector 96 is spaced apart from the inner wall of the first airflow channel T21 (i.e., the surface of the bottom wall 81 of the light source bracket 14), and can be fixed to the bottom wall 81 or other positions of the light source bracket 14 by a connecting structure (not shown in the figure). By arranging the reflector 96 at intervals, the position of the reflector 96 can be closer to the air hole K8, which is conducive to reflecting back more light and improving the luminous efficiency of the lamp tube 23.

[0222] In this embodiment, the reflecting surface P2 of the reflecting element 96 can be a flat surface or a curved surface.

[0223] For example Fig. 27 and Fig.28 In the figure, the reflecting surface P2 of the reflecting member 96 is a plane. Fig.29 In the embodiment, the reflecting surface P2 of the reflecting member 96 is a curved surface convexly arranged toward the direction of the air hole K8. The convexly arranged curved reflecting surface P2 can prevent a part of the reflected light from being reflected onto the lamp tube 23, thereby emitting toward the light outlet K1.

[0224] The reflector 96 can be an additional sheet structure fixed to the light source bracket 14 by a connector or bonding; the reflector 96 can also be a reflective film layer pre-formed on the surface of the bottom wall 81 by metal deposition, spraying or other methods, and it only needs to have a reflective surface P2 that can reflect light.

[0225] In the above embodiment (see Figure 8-Figure 10 ), the first sensing circuit board 53 carrying the trigger switch 51 and the skin color recognition circuit board 35 are integrated into an L-shaped circuit board 54, while the second sensing circuit board 57 carrying the conductive probe 58 is separated from the skin color recognition circuit board 35.

[0226] The present disclosure also provides some different embodiments.

[0227] Figure 30-Figure 33A different embodiment is shown. In this embodiment, based on the above embodiment, the second sensing circuit board 57 carrying the conductive probe 58 is integrated at the other end of the skin color recognition circuit board 35, so that the first sensing circuit board 53, the skin color recognition circuit board 35 and the second sensing circuit board 57 are integrated into a U-shaped circuit board 98, and the U-shaped circuit board 98 is fixed on the light-transmitting bracket 15. In this way, the total number of circuit boards is further reduced, and the complexity of the circuit board installation or the electrical connection structure between circuit boards is reduced.

[0228] For this embodiment, the second sensing circuit board 57 faces the filter component 11a, so a conductive probe 58 (such as a conductive probe 61) can be set to extend in a direction perpendicular to the filter component 11a, that is, the conductive probe 58 extends along the light emitting direction X toward one side of the filter component 11a.

[0229] The embodiment also provides a filter component 11a and Fig.14 The filter assembly 11 shown in the figure is structurally different so as to facilitate lateral electrical conduction with the conductive probe 58 extending therefrom in a direction perpendicular to the filter assembly 11a.

[0230] See also Fig.33 The filter assembly 11a 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 is provided with a mounting groove C4 formed by a concave at one end away from the plug-in port K2 along the plug-in direction Y1, and the conductive part 59a is a conductive block mounted on the mounting groove C4; the conductive part 59a has a void-avoiding position W1, and the void-avoiding position W1 is a void-avoiding groove C8 formed by a concave from the surface of the conductive part 59a toward the conductive probe 58. The void-avoiding groove C8 can be concave to a certain thickness, or it can be concave through both sides of the thickness direction of the conductive part 59a. The filter mounting frame 62 includes two end walls 83 located at intervals along the thickness direction of the filter assembly 11a (parallel to the light emitting direction X in this embodiment) of the mounting groove C4, and the mounting groove C4 is located between the two end walls 83. The conductive probe 58 is a conductive probe 61. The end wall 83 of the two end walls 83 close to the conductive probe 61 is provided with a plurality of channel grooves C7 formed inwardly along the plug-in direction Y1. The plurality of conductive probes 61 correspond to the channel grooves C7 along the thickness direction of the filter component 11a respectively, and can extend into the installation groove C4 through the channel grooves C7 to abut the conductive part 59a.

[0231] Thus, when the filter assembly 11a is inserted into the slot C2 along the insertion direction Y1, due to the setting of the channel groove C7, the end wall 83 will not block the conductive probe 61 from being inserted and contacting the conductive portion 59a, and when the filter assembly 11a is plugged in place, the conductive probe 61 can pass through the channel groove C7 and abut against the conductive portion 59a. Of course, in order to prevent the conductive probe 61 from obstructing the conductive portion 59a when the filter assembly 11a is inserted, the conductive probe 61 can be configured as a retractable spring pin, and the end of the conductive probe 61 can be configured as a hemispherical shape, so that the conductive probe 61 can be retracted with the guidance of the hemispherical surface to allow the conductive portion 59a to move to the position corresponding to the conductive probe 61, thereby ensuring electrical contact.

[0232] In this embodiment, different types of filter components 11a (eg, different filter bands) have conductive portions 59a with different clearances W1. Fig.33 The conductive part 59a-1 of another type of filter component 11a is additionally shown by a dotted line. The conductive part 59a-1 has two avoidance positions W1, which is different from the conductive part 59a which has only one avoidance position W1. In this way, the filter component 11a equipped with the conductive part 59a-1 and the filter component 11a equipped with the conductive part 59a can be identified as different types of filter components 11a.

[0233] Continue to see Figure 30-Figure 33 In this embodiment, the trigger switch 51 can be arranged to face the filter assembly 11a, and the trigger portion 52 can be a rotating member 99 rotatably mounted near the entrance of the slot C2 of the light-transmitting bracket 15. When the filter assembly 11a is inserted, the filter assembly 11a can push the rotating member 99 to rotate in a direction close to the trigger switch 51, and when the filter assembly 11a is inserted into place, the filter assembly 11a presses the rotating member 99 against the trigger switch 51 to trigger the trigger switch 51. In this solution, the filter assembly 11a does not need to be provided with the aforementioned protruding portion 55 (see Fig.14 ), the maximum dimension of the filter component 11a in the thickness direction is small, which is beneficial to reducing the space occupied by the filter component 11a.

[0234] Of course, the trigger switch 51 in this embodiment can also be triggered by the protruding portion 55 along the plugging and unplugging direction Y1 (see Figure 8 ), which is not limited here.

[0235] Figure 34-Figure 35Another different embodiment is shown. In this embodiment, the trigger switch 51 and multiple conductive probes 58 (such as conductive probes 61) are integrated on the same sensing circuit board 49, and the multiple conductive probes 61 and the trigger switch 51 are arranged at intervals on the board surface of the sensing circuit board 49. The sensing circuit board 49 is installed on the outer surface of the first peripheral side plate 28 of the light-transmitting bracket 15, and the trigger switch 51 and the conductive probe 58 are both facing the insertion direction of the filter component 11b, that is, the same direction as the entrance of the slot C2.

[0236] In this embodiment, a protruding plate 100 protruding along the plugging and unplugging direction Y1 is protruded from the outer surface of the first peripheral side plate 28 (ie, the first peripheral side surface P31 ), and a clamping structure 101 is connected to the plate surface of the protruding plate 100 .

[0237] A clamping gap f3 is defined between the clamping structure 101 and the first peripheral side surface P31, and the sensing circuit board 49 is fitted in the clamping gap f3. The clamping structure 101 includes two clamping plates 102 spaced apart from each other, and the trigger switch 51 is clamped between the two clamping plates 102.

[0238] Optionally, a plurality of conductive probes 61 are arranged on both sides of the trigger switch 51, for example Fig.35 As shown, four conductive probes 61 arranged in a rectangular shape are provided on one side of the trigger switch 51, and two conductive probes 61 are provided on the other side. The conductive probes 61 and the trigger switch 51 are arranged in sequence along the width direction of the filter assembly 11b.

[0239] Continue to see Fig.34 and Fig.35 This embodiment also provides a filter assembly 11b having a structure different from that of the filter assembly 11. The filter assembly 11b 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 main frame 64 and a holding head 65. The main frame 64 is used to mount the filter 63 and is inserted and matched in the slot C2 to serve as an insertion portion of the filter mounting frame 62. The holding head 65 is plugged and matched with one end of the main frame 64 and abuts against the filter 63. The holding head 65 includes an insertion section 103 and a protruding section 67. The insertion section 103 is inserted and matched with the main frame 64. The protruding section 67 is connected to the insertion section 103 and extends to the side of the insertion section 103, serving as a protruding portion 55 for acting on the trigger switch 51 and the conductive probe 58.

[0240] The surface of the protruding section 67 facing the sensing circuit board 49 includes a trigger surface P41 and a conductive surface P42. The trigger surface P41 corresponds to the trigger switch 51, and the conductive surface P42 is located on both sides of the trigger surface P41 and corresponds to the conductive probes 58 on both sides. In this way, when the filter component 11b is inserted into the slot C2, the trigger surface P41 of the protruding section 67 presses against the trigger switch 51, so that the trigger switch 51 is triggered and a signal indicating that the filter component 11b is plugged in is obtained. At the same time, the conductive surface P42 acts as the conductive probe 58 that the conductive portion 59b contacts.

[0241] In this embodiment, the filter sheets 63 of the filter components 11b of different models have different filter bands, and correspondingly, the conductive surfaces P42 of the filter components 11b of different models have different avoidance positions, so that the filter components 11b of different models can conduct different conductive probes 58, and thus the models of the filter components 11b can be identified by the different avoidance position settings of the conductive surface P42. The avoidance position can be embodied as a concave or insulating treatment of a selected position of the conductive surface P42.

[0242] In this embodiment, the conductive probe 58 and the trigger switch 51 are integrated on the same side of a circuit board and are both facing the plug-in direction Y1 of the filter component 11b. The protruding section 67 on the inserted filter component 11b can simultaneously trigger the trigger switch 51 and electrically contact the conductive probe 58 along the plug-in direction Y1, thereby realizing plug-in position identification and filter component 11b model identification. The structure is compact and reasonable, and it is easy to use.

[0243] In this embodiment, optionally, the trigger surface P41 is concave relative to the conductive surface P42, so as to adapt to the situation where the trigger switch 51 and the conductive probe 61 extend to different heights.

[0244] Figure 36-Figure 39 Yet another different embodiment is shown.

[0245] In this embodiment, the sensing component 48 includes a sensing circuit board 49 and a filter model identification circuit 60 provided on the sensing circuit board 49. The filter model identification circuit 60 includes a plurality of conductive probes 58 spaced apart from each other, and the conductive probes 58 are fixed to the sensing circuit board 49. The sensing circuit board 49 is fixed to the second peripheral side plate 29. The sensing circuit board 49 is provided separately and is not integrated with other circuit boards (such as the skin color identification circuit board 35). The board surface of the sensing circuit board 49 faces the filter component 11c, and the plurality of conductive probes 58 extend from the sensing circuit board 49 toward the board surface of the filter component 11c. As shown in the figure, the sensing circuit board 49 is located in front of the slot C2 along the light emitting direction X.

[0246] The filter assembly 11 c includes a conductive portion 59 c having a clearance W1 , and the clearance W1 corresponds to a portion of the plurality of conductive probes 58 .

[0247] When the filter assembly 11 c is engaged with the slot C2 , the conductive portion 59 c is electrically connected to the other conductive probes 58 except the conductive probe 58 corresponding to the avoidance position W1 .

[0248] Optionally, the sensing component 48 further includes a spring holder 105, which is fixed to the surface of the sensing circuit board 49 facing the filter component 11c. The conductive probe 58 is a conductive spring 104, which is supported by the spring holder 105. 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 component 11c, and is used to elastically press the contact conductive portion 59c.

[0249] 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 .

[0250] See again Figure 36-Figure 39 , this embodiment provides a filter assembly 11c with a different structure. The filter assembly 11c 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. The metal frame member 109 has a light-transmitting area S1 and a filter slot C5, and the filter slot C5 extends along the plug-in direction Y1 of the filter assembly 11c, and the light-transmitting area S1 is connected to the filter slot C5; the filter 63 is matched with the filter slot C5 and covers the light-transmitting 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 filter 63 is sandwiched between the tail member 116 and the holding head 65. The conductive portion 59 c is a portion of the tail of the metal frame 109 close to one side of the sensing circuit board 49 , and the avoidance position W1 is a avoidance groove C8 opened in the metal frame 109 .

[0251] Thus, when the filter assembly 11c is inserted, the tail end of the metal frame member 109 of the filter assembly 11c as the conductive portion 59c corresponds to the conductive spring piece 104. The conductive spring pieces 104 corresponding to the vacant slots C8 are not connected by the conductive portion 59c. The conductive spring pieces 104 not corresponding to the vacant slots C8 elastically abut against the metal frame member 109, and are thus electrically connected by the conductive portion 59c of the metal frame member 109.

[0252] In this embodiment, there are six conductive springs 104 in the filter assembly 11c, and the six conductive springs 104 are arranged in a row. Different types of filter assemblies 11c have different numbers or positions of the gap-avoiding grooves C8. Fig.38 Four different types of filter components 11c are shown in the figure, and the arrangement positions and quantities of the avoidance positions W1 of the four different types are different, so that the four different types of filter components 11c can realize the conduction of different conductive springs 104, thereby making the model of the inserted filter component 11c identifiable.

[0253] Continue to see Fig.39 In this embodiment, the metal frame member 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 11c, 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 piece 116 are respectively plugged into and matched at both ends of the filter slot C5 and clamped at both ends of the filter 63. The first metal plate 110 faces the sensing circuit board 49, and the portion of the first metal plate 110 close to one end of the tail piece 116 serves as a conductive portion 59c and is provided with a gap-avoiding slot C8. The first metal plate 110 and the second metal plate 111 are provided with opposite light-transmitting holes, and a light-transmitting area S1 is formed at the light-transmitting holes.

[0254] Fig.40 and Fig.41 Another structure of the filter assembly 11d is shown. Fig.39 The optical filter assembly 11c is similar to the optical filter assembly 11d in that the optical filter assembly 11d includes an optical filter mounting frame 62 and an optical filter 63, and 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, an end member 116 and a holding head 65.

[0255] The filter component 11d and Fig.39 The difference between the filter assembly 11c and the filter assembly 11c mainly lies in the structure of the metal frame member 109.

[0256] See also Fig.40 and Fig.41 The metal frame member 109 of the filter assembly 11d includes a third metal plate 113 and two L-shaped 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 a light-transmitting area S1.

[0257] When the filter assembly 11d is inserted into the slot C2, Fig.38 , the third metal plate 113 faces the sensing circuit board 49, and the portion of the third metal plate 113 near the end of the tail piece 116 serves as the conductive portion 59d and is provided with a gap-avoiding groove C8. The gap-avoiding groove 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. Optionally, the tail piece 116 has an insulating protrusion 115, and when the tail piece 116 is plugged into the third metal plate 113, the insulating protrusion 115 is matched with the gap-avoiding groove C8.

[0258] 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 void groove C8 is not conducted.

[0259] Different types of filter components 11d have different gap-avoiding grooves C8 and insulating protrusions 115, such as Fig.40 Another type of filter assembly 11d additionally shown by dotted lines in the figure has two avoidance slots C8 as avoidance positions W1, which is different from the filter assembly 11d shown on the left side which has only one avoidance position W1. In this way, after being inserted into the slot C2, the model of the filter assembly 11d of different types can be identified.
