It can achieve hair removal, skin rejuvenation, hair growth, whitening, freckle removal, wrinkle removal and other effects by emitting suitable treatment light (such as light of a special band or different types of light) to act on the skin.

[0120] See also Figure 2 In this embodiment, the skin treatment device 1000 includes a device body 10 and a filter assembly 11, and the filter assembly 11 is pluggable and matched with the device body 10 along the plug-in direction Y1. Figure 1 In the embodiment, the filter assembly 11 is installed in the device body 10, and the light emitted by the light source of the skin treatment device 1000 is filtered by the filter assembly 11 and then emitted to obtain the treated light; Figure 2 In the embodiment, the filter component 11 is pulled out from the device body 10 , and the light emitted by the light source of the skin treatment device 1000 will not be affected by the filter component 11 .

[0121] In this embodiment, the device body 10 is provided with a cover 42, which is used to close the plug-in port K2 on the device body 10 for plugging and unplugging the filter assembly 11. Before plugging and unplugging the filter assembly 11, the cover 42 needs to be opened to expose the plug-in port K2; after the plug-in and unplugging of the filter assembly 11 are completed, the cover 42 can be covered to close the plug-in port K2 to ensure dust prevention. In the use state where the filter assembly 11 is not inserted, the plug-in port K2 can also be closed by the cover 42 to achieve dust prevention.

[0122] See also Figure 3 and Figure 4 In this embodiment, the device body 10 mainly includes a housing 12, an optical system 13, an internal bracket 40, a heat dissipation system 16, a main control board 17 and a power supply 18. The internal bracket 40, 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 internal bracket 40 is 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).

[0123] 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 internal bracket 40, 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.

[0124] 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.

[0125] 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.

[0126] In this embodiment, the plug-in port K2 of the device body 10 is disposed on the upper shell 19 of the housing 12 , and the cover 42 is connected to the upper shell 19 and can close or open the plug-in port K2 .

[0127] 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.

[0128] The main control board 17 may have a switch element. When a user presses a button cover 41 that is exposed from the housing 12 , the button cover 41 will press down the switch element to start or stop the skin treatment device 1000 .

[0129] 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 .

[0130] The power source 18 can be a rechargeable battery to facilitate replenishing electrical energy.

[0131] See also Figure 4 and Figure 5 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.

[0132] The light source 22 is used to generate light. In this embodiment, the light source 22 is a lamp tube 23, which can be fixedly connected and electrically connected to the main control board 17, and the lamp tube 23 can be controlled by the main control board 17 to generate light.

[0133] 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.

[0134] 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.

[0135] 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.

[0136] Continue to see Figure 4 and Figure 5 In this embodiment, the internal bracket 40 includes a light source bracket 14 and a light-transmitting bracket 15 .

[0137] 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.

[0138] The light source bracket 14 has a mounting cavity Q2, the reflector cup 24 is disposed in the mounting cavity Q2, the lamp tube 23 extends into the mounting cavity Q2 and is disposed on the side of the reflector cup 24 away from the light source bracket 14. In this way, the light emitted by the light source 22 can be reflected toward the light emitting direction X through the reflector cup 24.

[0139] Continue to see Figure 4 and Figure 5 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.

[0140] 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.

[0141] 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. 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.

[0142] Continue to see Figure 3 and Figure 4 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 .

[0143] 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.

[0144] 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 .

[0145] 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.

[0146] 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 .

[0147] Continue to see Figure 3 and Figure 4 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.

[0148] 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.

[0149] 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.

[0150] See also Figures 5 to 7 In this embodiment, the cover 42 includes a cover plate 43, a connecting portion 44 and a snap-fit ​​structure 45. The cover 42 is rotatably connected to the housing 12 through the connecting portion 44, and is used to rotate to open or close the plug-in port K2. When the cover 42 is closed at the plug-in port K2, the snap-fit ​​structure 45 snaps into and fits with one end of the filter assembly 11 near the plug-in port K2. For example, in this embodiment, one end of the filter mounting frame 69 near the plug-in port K2 is a holding end 46 for convenient hand-holding. The snap-fit ​​structure 45 of the cover 42 snaps into and fits with the holding end 46.

[0151] In the skin treatment device 1000 of this embodiment, the cover 42 can close or open the plug-in port K2, which is convenient for plugging and unplugging the filter assembly 11. When the filter assembly 11 is inserted from the plug-in port K2 for use, the cover 42 can close the plug-in port K2, and the cover 42 can be positioned and engaged on the filter assembly 11 through its snap-fit ​​structure 45. The cover 42 is accurately positioned, reliably connected, and not easy to fall off. After the filter assembly 11 is pulled out, the cover 42 can still be used to close the plug-in port K2 to prevent dust from entering the skin treatment device 1000 from the plug-in port K2.

[0152] In addition, when the cover 42 needs to be opened, the cover 42 does not need to be completely separated from the shell 12, but can remain connected to the shell 12 through the connecting portion 44, thereby reducing the risk of losing the cover 42.

[0153] However, some known covers 42 have problems such as loose connection, insufficient positioning accuracy or easy loss.

[0154] Continue to see Figures 5 to 7 In this embodiment, one end of the filter assembly 11 near the plug-in port K2 is provided with a snap-in convex edge 47 protruding toward both sides along the thickness direction. The snap-in structure 45 of the cover 42 includes two first snap hooks 48, and the hook portions 49 at the ends of the two first snap hooks 48 extend toward each other to define a first snap-in hole K3 (see Figure 7 ), the snap-fitting protrusion 47 is snap-fitted in the first snap-fitting hole K3 in a detachable manner. By making the snap-fitting protrusion 47 of the filter assembly 11 fit in the first snap-fitting hole K3 of the cover 42, the cover 42 can be reliably and accurately positioned, reducing the possibility of the cover 42 being installed inaccurately or falling off.

[0155] In this embodiment, optionally, the housing 12 includes two inclined walls 73, and the plug-in port K2 is defined between the two inclined walls 73. The inclined wall 73 has a first inclined surface P3, and the plug-in port K2 with a larger outer surface and a smaller inner surface is defined between the two first inclined surfaces P3. The first hook 48 has a second inclined surface P4 supported on the first inclined surface P3. Through the cooperation of the first inclined surface P3 and the second inclined surface P4, the cover 42 can be easily guided to enter the position that cooperates with the plug-in port K2 of the housing 12, that is, the inclined wall 73 of the housing 12 can play a role in guiding the cover 42 to enter.

[0156] In this embodiment, the cover 42 further includes a second hook 50, which is connected to the cover plate 43 and is located on the side of the clamping structure 45 away from the connecting portion 44. The housing 12 is provided with a second clamping hole K4, and when the cover 42 is closed at the plug-in port K2, the second hook 50 is detachably clamped to the second clamping hole K4. In this way, when the cover 42 is connected to the housing 12, the second hook 50 can also be clamped to the second clamping hole K4 of the housing 12, thereby further improving the connection reliability of the cover 42 on the housing 12.

[0157] In this embodiment, in order to realize the rotational connection between the connecting portion 44 and the housing 12, the housing 12 is provided with a connecting hole K8, and the connecting portion 44 includes a column section 51 and a protruding end 52, one end of the column section 51 is connected to the cover plate 43, and the other end is connected to the protruding end 52. The column section 51 can be movably inserted into the connecting hole K8, and the protruding end 52 penetrates into the inner side of the housing 12. The cross section of the protruding end 52 is larger than the connecting hole K8. In this way, the rotatable cooperation between the connecting portion 44 and the housing 12 can be realized, and the connection portion 44 can be prevented from being disengaged from the housing 12. Optionally, the length of the column section 51 is greater than the thickness of the housing 12, so that when the cover 42 is opened, it can be pulled outward relative to the housing 12 for a distance, so that when the cover 42 is opened, the cover plate 43 can be pulled to a position farther away from the housing 12, which is conducive to avoiding obstruction of the plugging and unplugging of the filter assembly 11. Optionally, the front end surface of the protruding end 52 is conical, so as to facilitate the insertion of the protruding end 52 into the connecting hole K8.

[0158] Continue to see Figures 5 to 7In this embodiment, the outer surface of the shell 12 is provided with a recessed groove C1, and when the cover 42 closes the plug-in port K2, the cover plate 43 is matched with the recessed groove C1. In this way, the outer surface of the cover 42 and the outer surface of the shell 12 can be flush and not protruding in the closed state. Optionally, the cover plate 43 includes a circular plate portion 53 and a protruding plate portion 54 connected to one radial side of the circular plate portion 53, and the inner side surface of the protruding plate portion 54 has a boss 55 protruding inwardly along the thickness direction of the cover plate 43, and the connecting portion 44 is connected to the boss 55. The bottom surface of the recessed groove C1 is concave at a position corresponding to the boss 55 to form an inner groove C3, and the shell 12 has a connecting hole K8 that passes through the shell 12 from the inner groove C3.

[0159] The sealing cover 42 in this embodiment can be injection molded from silicone or other flexible materials.

[0160] See also Figure 8 and Fig. 9 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. The first peripheral side panel 28 and the second peripheral side panel 29 are opposite to each other, and the third peripheral side panel 30 and the fourth peripheral side panel 31 are opposite to each other.

[0161] 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 .

[0162] 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 .

[0163] In this embodiment, the first peripheral side plate 28, the fourth peripheral side plate 31 and the second peripheral side plate 29 can be optionally combined into an integrated U-shaped frame 32, and the third peripheral side plate 30 is used as a cover plate 33, and the cover plate 33 is detachably covered on the opening of the U-shaped frame 32, so as to enclose the light outlet channel T3 of the light-transmitting bracket 15. In this way, when it is necessary to install the light-transmitting member 26 and the fixed filter 25 on the light-transmitting bracket 15, the light-transmitting member 26 and the fixed filter 25 can be conveniently loaded 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.

[0164] 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.

[0165] Continue to see Figure 8 and Fig. 9 In this embodiment, the device body 10 of the skin treatment device 1000 further includes a trigger component 56, a movable component 57 and an elastic component 58, which are used to sense whether the filter component 11 is inserted or not.

[0166] The trigger assembly 56 is connected to the light-transmitting bracket 15 of the internal bracket 40. The movable member 57 can be movably matched with the light-transmitting bracket 15 of the internal bracket 40 and corresponds to the trigger assembly 56 along the moving direction X1; the moving direction X1 intersects the plug-in direction Y1 vertically or obliquely. The elastic member 58 elastically presses against the movable member 57 to elastically press the movable member 57 against the position of the entrance of the blocking slot C2. When the filter assembly 11 is inserted, the filter assembly 11 can push the movable member 57 to overcome the elastic force of the elastic member 58 and move to press against the trigger assembly 56.

[0167] In the skin treatment device 1000 of this embodiment, when the filter assembly 11 is not inserted, the movable member 57 is elastically supported by the elastic member 58 at a position that blocks the plug-in port K2, which can achieve the effect of avoiding light leakage and dust prevention; when the filter assembly 11 is inserted, the filter assembly 11 can push the movable member 57 to move away from the plug-in port K2, so that the filter assembly 11 can be normally inserted into the slot C2 for use. In addition, when the filter assembly 11 is inserted and matched with the slot C2, the filter assembly 11 pushes the movable member 57 to abut against the trigger assembly 56, so that the trigger switch 62 is triggered. In the present disclosure, when the trigger switch 62 is triggered, it can indicate a signal indicating that the filter assembly 11 is plugged in place.

[0168] Therefore, the skin treatment device 1000 of this embodiment can conveniently adapt to the insertion state and the removal state of the filter component 11, has a better dust and light leakage prevention effect, and can identify whether the filter component 11 is plugged in place.

[0169] However, in some known skin treatment devices 1000, when the filter assembly 11 is unplugged, the plug-in port K2 is exposed to the outside, which may cause light leakage or dust ingress problems.

[0170] In this embodiment, optionally, a side frame portion 59 is connected to the side of the light-transmitting bracket 15 of the internal bracket 40 at the entrance of the slot C2. In this embodiment, the side frame portion 59 is connected to the first peripheral side wall. The side frame portion 59 has a slide groove C4 extending along the movable direction X1; one end of the slide groove C4 is connected to the slot C2, and the other end is connected to the trigger assembly 56, and the entrance of the slot C2 is arranged in the side frame portion 59 and is located behind the slide groove C4 along the light emitting direction X of the skin treatment device 1000. The movable member 57 can be slidably matched with the slide groove C4, and the elastic member 58 is arranged in the slide groove C4 and elastically presses against the movable member 57 toward the side close to the slot C2, so as to elastically support the movable member 57 at a position extending out of the slide groove C4 and blocking the entrance of the slot C2. Through the side frame portion 59 with the slide groove C4, the elastic member 58 and the movable member 57 can be conveniently and reliably accommodated and installed, and it is conducive to ensuring that the sliding member slides in a limited space to avoid interference with other components.

[0171] See also Fig.10 In this embodiment, the movable member 57 includes a connected abutting portion 66 and a convex edge 67, and the slide groove C4 includes a first hole segment K6 and a second hole segment K7. The first hole segment K6 is connected to the slot C2, and the second hole segment K7 is connected to the first hole segment K6. The slide groove C4 is a stepped hole in which the cross section of the first hole segment K6 is smaller than that of the second hole segment K7. The abutting portion 66 passes through the first hole segment K6, and the convex edge 67 is matched with the second hole segment K7; the elastic member 58 abuts the convex edge 67 and can elastically press the convex edge 67 against the step surface P5 between the first hole segment K6 and the second hole segment K7. In this way, the elastic member 58 elastically presses the convex edge 67 against the step surface P5, which can ensure that when the filter assembly 11 is not inserted, the movable member 57 remains at a certain position to close the plug-in port K2.

[0172] Optionally, the skin treatment device 1000 further includes a connecting frame 60, which is detachably connected to the side frame portion 59 and is located on the side of the slide slot C4 away from the slot C2. The trigger assembly 56 is fixedly connected to the connecting frame 60 and extends out of the slide slot C4, and the elastic member 58 elastically abuts between the movable member 57 and the connecting frame 60. In this way, during assembly, the trigger assembly 56 can be first mounted on the connecting frame 60, and then the trigger assembly 56 and the connecting frame 60 can be mounted on the side frame portion 59 together, which has the effect of convenient installation.

[0173] In this embodiment, the trigger assembly 56 includes a trigger circuit board 61 and a trigger switch 62, and the trigger switch 62 is connected to one side of the trigger circuit board 61. The connecting frame 60 includes a plate portion 63 and two hook portions 64; the plate portion 63 is provided with a matching hole K5 that passes through along the moving direction X1, and the surface of the plate portion 63 on the side away from the movable member 57 is provided with two hook portions 64, and the two hook portions 64 are respectively located on both sides of the matching hole K5. The trigger circuit board 61 is attached to the surface of the plate portion 63 on the side away from the movable member 57, and is clamped between the two hook portions 64; the trigger switch 62 is matched with the matching hole K5 and faces the movable member 57. During assembly, the trigger circuit board 61 of the trigger assembly 56 is clamped between the two hook portions 64, and the trigger switch 62 extends into the matching hole K5, so that the trigger assembly 56 and the connecting frame 60 are fixed together, which is convenient for being installed together on the side frame portion 59. Optionally, matching slots C5 are formed on both sides of the side frame portion 59 , and matching hooks 74 are formed on both sides of the connecting frame 60 , and the matching hooks 74 are engaged with the matching slots C5 .

[0174] In this embodiment, optionally, there are two elastic members 58, and the two elastic members 58 are respectively located on both sides of the trigger switch 62. In this way, when the filter assembly 11 is inserted, the filter assembly 11 can drive the movable member 57 to smoothly retreat and press against the trigger switch 62 located between the two elastic members 58. Optionally, a positioning groove C6 is provided on the side of the movable member 57 close to the elastic member 58, and one end of the elastic member 58 is matched with the positioning groove C6, so as to facilitate the reliable positioning of the elastic member 58 on the movable member 57. Optionally, a positioning boss 68 is provided on the side of the connecting frame 60 close to the elastic member 58, and the other end of the elastic member 58 is sleeved outside the positioning boss 68, so that the relative position of the elastic member 58 and the connecting frame 60 can be ensured.

[0175] Main references Fig.10 In this embodiment, the side surface of the movable member 57 facing the plug-in port K2 includes a first guide surface P1, and the filter assembly 11 has a second guide surface P2 at the front end of the insertion direction of the filter assembly 11. When the filter assembly 11 is inserted along the plug-in direction Y1, the second guide surface P2 pushes against the first guide surface P1 in an oblique wedge manner to drive the movable member 57 to retreat along the movable direction X1. Optionally, the first guide surface P1 and the second guide surface P2 are inclined surfaces or arc surfaces inclined relative to the plug-in direction Y1. The cooperation of the first guide surface P1 and the second guide surface P2 facilitates the movable member 57 to smoothly push the movable member 57 to overcome the elastic force of the elastic member 58 and retreat when the filter assembly 11 is inserted.

[0176] In this embodiment, the filter assembly 11 includes a filter mounting frame 69 and a filter 70, and the filter 70 is mounted on the filter mounting frame 69. The filter mounting frame 69 includes a first side wall 71 and a second side wall 72, and the filter 70 is sandwiched between the first side wall 71 and the second side wall 72. The first side wall 71 and the second side wall 72 are higher than the filter 70 along the thickness direction of the filter assembly 11, and when the filter assembly 11 is inserted into the slot C2, the movable member 57 abuts against the first side wall 71 and the second side wall 72. In this way, it is possible to prevent the movable member 57 from touching and damaging the filter 70 when the filter assembly 11 is inserted.
