[0079] The technical solutions in the embodiments of the present disclosure will be clearly and completely described below in conjunction with the drawings in the embodiments of the present disclosure. Obviously, the described embodiments are only part of the embodiments of the present disclosure, rather than all of the embodiments.

When an element is considered to be "connected to" another element, it may be directly connected to the other element or there may also be a centered element. When an element is considered to be "set on" another element, it may be directly set on the other element or there may also be a centered element. The terms "vertical", "horizontal", "left", "right" and similar expressions used herein are for illustrative purposes only.

[0081] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art. The terms used herein in the specification of the present disclosure are only for the purpose of describing specific embodiments and are not intended to limit the present disclosure. The term "or / and" used herein includes any and all combinations of one or more related listed items.

[0082] Some embodiments of the present disclosure are described in detail. In the absence of conflict, the following embodiments and features of the embodiments can be combined with each other.

[0083] Example

[0084] Figure 1 A three-dimensional view of the skin treatment device 100 provided in this embodiment, Figure 2 for Figure 1 An expanded view of the skin treatment device 100.

[0085] See also Figure 1 This embodiment provides a skin treatment device 100, which can be a hair removal device, a skin rejuvenation device, a hair growth device or other skin treatment devices, which can achieve the effects of hair removal, skin rejuvenation, hair growth, whitening, freckle removal, wrinkle removal, etc. by emitting appropriate light to act on the skin.

[0086] See also Figure 2 and Figure 3 In this embodiment, the skin treatment device 100 includes a device body 110 and a filter assembly 120. The device body 110 is provided with a plug-in port K1, and the filter assembly 120 is detachably mounted on the device body 110 through the plug-in port K1. The device body 110 may be provided with a detachable cover 108 for covering the plug-in port K1.

[0087] See also Figure 4In this embodiment, the device body 110 mainly includes a housing 101, a light source 102, a light-transmitting bracket 103 and a light-transmitting member 104. The housing 101 has an internal space Q1, the light source 102 and the light-transmitting bracket 103 are respectively fixedly installed in the internal space Q1, and the light-transmitting member 104 is installed on the light-transmitting bracket 103 and corresponds to the light source 102.

[0088] The light-transmitting bracket 103 has a slot C1 corresponding to the plug-in port K1, and the slot C1 is located between the light-transmitting member 104 and the light source 102. The filter assembly 120 can be inserted into the slot C1 through the plug-in port K1 and can also be removed from the slot C1 through the plug-in port K1.

[0089] When the filter assembly 120 is installed in the slot C1, the light emitted by the light source 102 can be filtered by the filter assembly 120 and then emitted through the light-transmitting element 104, thereby acting on the skin.

[0090] The light source 102 can be a lamp tube that can generate different types of light. For example, the lamp tube can be used to generate laser, which is a laser lamp tube, and the skin treatment device 100 is a laser skin treatment device; for example, the lamp tube 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 100 is an intense pulsed light skin treatment device; for example, the lamp tube can be an LED lamp tube, and so on.

[0091] In this embodiment, the following mainly uses a xenon lamp as an example for explanation. The light-emitting principle of this type of skin treatment device 100 is: a capacitor is connected to a power source, and a transformer component is used to step up 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 to instantly release a strong pulse of light, thereby completing one light emission.

[0092] The light-transmitting member 104 can be a light-transmitting crystal, such as sapphire, and the surface on the light-emitting side thereof can be used as a 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 light exposure can be conducted to the light-transmitting member 104, reducing the burning sensation of the skin and improving the user experience. Of course, the light-transmitting member 104 can also be made of other suitable optical materials, which is not limited here.

[0093] The device body 110 may further include a fixed filter 105, which is fixedly mounted on the light-transmitting bracket 103 and may be disposed on a side of the slot C1 close to the light-transmitting member 104 (eg, Figure 4 ), and may also be disposed on the side of the slot C1 close to the light source 102.

[0094] The device body 110 may also include other structural or functional components, such as a reflective member 106 for reflecting light from the light source 102, a cold compress assembly 107 for cooling the light-transmitting member 104, an air-cooling assembly and an air-cooling channel for air-cooling, etc., which can be specifically configured according to needs.

[0095] Figure 5-Figure 7 The filter assembly 120 of this embodiment is shown, and the filter assembly 120 can be inserted into or removed from the plug-in port K1 of the device body 110 to provide or remove the filtering effect as needed.

[0096] See also Figure 5 and Figure 6 In this embodiment, the filter assembly 120 includes a filter 10 and a filter mounting frame 20. The filter mounting frame 20 is used to mount the filter 10.

[0097] Among them, combined with reference Figure 4 , the filter 10 can be used to filter out a portion of a specific wavelength band from the light emitted by the light source 102, so that the filtered light can achieve a specific skin treatment effect, such as hair removal, skin rejuvenation, hair growth, whitening, freckle removal, wrinkle removal, etc. In addition, for the skin treatment device 100 also provided with a fixed filter 105, the filter 10 of the filter assembly 120 and the fixed filter 105 can achieve a combined filtering effect to achieve a more accurate range of filtering.

[0098] Continue to see Figure 5 and Figure 6 In this embodiment, the filter mounting frame 20 includes a filter support 21 and an elastic pressing member 22 .

[0099] The filter holder 21 has a light-transmitting area K4, which passes through the filter holder 21 along the thickness direction of the filter holder 21 and is used to allow light to pass through. After the filter 10 is installed, the filter 10 covers the light-transmitting area K4, so that the light generated by the light source 102 can be filtered by the filter 10 and then propagated backward.

[0100] In this embodiment, the filter holder 21 includes a holding portion 23 and a mounting portion 24. The mounting portion 24 is connected to one end of the holding portion 23 along the second direction Y2. In this embodiment, the filter holder 21 is in the shape of a long strip extending along the second direction Y2. During installation, the user can hold the holding portion 23 by hand to operate the filter holder 21 or the filter assembly 120 to insert or remove the filter holder 21 or the filter assembly 120 into or remove the slot C1 of the device body 110 along the second direction Y2.

[0101] The mounting portion 24 includes a first side edge 25a and a second side edge 25b spaced apart along a first direction Y1, and the first side edge 25a and the second side edge 25b are respectively located on opposite sides of the light transmission area K4. The first direction Y1 is perpendicular to the second direction Y2. In this embodiment, the first direction Y1 is the width direction of the filter holder 21, and the second direction Y2 is the length direction of the filter holder 21. The first side edge 25a and the second side edge 25b extend along the second direction Y2, respectively, and the filter 10 is a rectangular sheet structure with a longer dimension along the second direction Y2 and a shorter dimension along the first direction Y1. Correspondingly, the through hole K2 is a bar-shaped hole extending along the second direction Y2.

[0102] In this embodiment, optionally, the extension range of the through hole K2 along the second direction Y2 covers the extension range of the filter 10 along the second direction Y2, the elastic pressing member 22 is a strip structure extending along the second direction Y2, and the extension range of the elastic pressing member 22 along the second direction Y2 covers the extension range of the filter 10 along the second direction Y2. In this way, it can be ensured that the elastic pressing member 22 contacts the entire length of the side edge of the filter 10, thereby improving the uniformity of force applied to each part of the filter 10 along the length direction.

[0103] In other embodiments, the corresponding first direction Y1 and second direction Y2 may not be perpendicular but may intersect at an angle.

[0104] In other embodiments, the filter 10 may also be in other shapes, and the corresponding filter holder 21 may also be adaptively deformed, which is not limited here.

[0105] In this embodiment, the mounting portion 24 and the holding portion 23 can be integrally formed, that is, the filter holder 21 is an integral structure, which can be formed by injection molding, stamping, machining, etc. The mounting portion 24 and the holding portion 23 can also be formed separately and connected to each other by welding, clamping, screw connection, etc.

[0106] In this embodiment, the mounting portion 24 and the holding portion 23 can be made of different materials, and the high temperature resistance of the material of the mounting portion 24 is higher than that of the holding portion 23. For example, the mounting portion 24 is made of metal materials such as aluminum alloy, and the holding portion 23 is made of plastic. The two can be fixedly connected after being molded separately, or the plastic holding portion 23 can be formed by secondary injection molding on the metal mounting portion 24. Since the mounting portion 24 needs to be inserted into the slot C1, some positions may be irradiated by the light source 102. Therefore, the mounting portion 24 is made of high temperature resistant material, which can reduce the degree of high temperature deformation of the mounting portion 24 caused by light, thereby avoiding extrusion or other effects on the filter 10 installed on the mounting portion 24.

[0107] In other embodiments, the mounting portion 24 and the holding portion 23 may also be made of the same material, for example, the mounting portion 24 and the holding portion 23 are made of the same metal material or plastic material.

[0108] In this embodiment, the holding portion 23 of the filter holder 21 is optionally provided with an air hole K3. The air hole K3 is a hole that passes through the holding portion 23 along the thickness direction. Figure 4 By providing the air holes K3 , the airflows in the spaces on both sides of the filter assembly 120 can be exchanged, thereby improving the heat dissipation uniformity on both sides of the filter assembly 120 .

[0109] Continue to see Figure 5 and Figure 6 In this embodiment, the first side 25a is provided with a through hole K2 that penetrates along the first direction Y1, and the through hole K2 is connected to the light-transmitting area K4. The elastic pressing member 22 is detachably connected to the through hole K2, and the filter 10 is elastically fixed between the elastic pressing member 22 and the second side 25b. Optionally, the elastic pressing member 22 is a silicone block or an elastic plastic block, and the elastic pressing member 22 can also be made of other flexible materials.

[0110] When the filter mounting frame 20 in this embodiment installs the filter 10, the filter 10 is inserted from the through hole K2 along the first direction Y1 and enters the light-transmitting area K4 to the second side 25b, and then the elastic pressing member 22 is installed into the through hole K2. While the elastic pressing member 22 is fixed in the through hole K2, the filter 10 is pressed between the second side 25b and the elastic pressing member 22, thereby completing the installation of the filter 10.

[0111] By using the filter mounting frame 20 of the present embodiment, the installation operation of the filter 10 is convenient and quick, and the elastic pressing member 22 is fixed at the through hole K2 of the first side 25a by the elastic deformation of the elastic pressing member 22, without the need for additional connection structures such as external clamping, screw connection, etc. In addition, one side of the filter 10 is pressed by the elastic pressing member 22, and the elastic pressing member 22 itself has the ability to deform, and can adapt to the dimensional deviation or thermal deformation that may occur in the filter 10 or the filter holder 21.

[0112] Continue to see Figure 5 and Figure 6 In this embodiment, optionally, a groove C2 is provided on the surface of the second side edge 25b facing the first side edge 25a (see also Figure 8 ), the groove C2 corresponds to the through hole K2. In this way, one side of the filter 10 can be inserted into the groove C2, thereby obtaining support from the second side 25b, thereby improving the support rigidity of the filter 10.

[0113] Continue to see Figure 5 and Figure 6In this embodiment, the filter holder 21 further includes a third side 25c and a fourth side 25d connected to both ends of the first side 25a and the second side 25b, respectively. The first side 25a, the second side 25b, the third side 25c and the fourth side 25d are connected to each other to form a rectangular frame structure, which defines the aforementioned light-transmitting area K4. The fourth side 25d can be combined with the holding portion 23 instead of being designed separately.

[0114] See also Figure 7 , the fourth side 25d is provided with a second groove C4 connected to the through hole K2 and the light-transmitting area K4, so that the end of the filter 10 close to the fourth side 25d can be fitted in the second groove C4, so that the end of the filter 10 can be supported by the fourth side 25d, further improving the support rigidity. Optionally, there is a second deformation gap f2 between the end of the filter 10 and the fourth side 25d (i.e., between the end of the filter 10 and the bottom surface of the second groove C4) to allow thermal deformation of the filter 10 along the second direction Y2, and to prevent the filter 10 from being squeezed and damaged due to elongation along the second direction Y2 due to heat or other reasons.

[0115] Similarly, the third side 25c is provided with a first groove C3 connected to the through hole K2 and the light-transmitting area K4, which is used to cooperate with the end of the filter 10 close to the third side 25c, and can also play a supporting role. Optionally, there is a first deformation gap f1 between the end of the filter 10 and the third side 25c (i.e., between the end of the filter 10 and the bottom surface of the first groove C3) to allow thermal deformation or other deformation of the filter 10 along the first direction Y1, and to prevent the filter 10 from being squeezed and damaged due to elongation along the second direction Y2 due to heat or other reasons.

[0116] See also Figure 8 , the thickness direction of the filter holder 21 is defined to be along the third direction Y3, and the third direction Y3 is perpendicular to the first direction Y1 and the second direction Y2. The first side edge 25a includes two pressing edges 26 spaced apart along the third direction Y3, the through hole K2 is defined between the two pressing edges 26, and the elastic pressing member 22 is elastically pressed between the two pressing edges 26. The two pressing edges 26 limit and fix the elastic pressing member 22 in the through hole K2, so that the elastic pressing member 22 and the first side edge 25a can be reliably fixed together.

[0117] In this embodiment, the elastic pressure piece 22 can be installed in the through hole K2 by means of interference fit, that is, the size (such as thickness size) of the elastic pressure piece 22 in the uncompressed state is slightly larger than the through hole K2. In this way, after the elastic pressure piece 22 is installed into the through hole K2, the elastic pressure piece 22 is compressed to a certain extent, so that it is elastically pressed between the two clamping edges 26 on both sides of the through hole K2, thereby realizing a reliable connection between the elastic pressure piece 22 and the first side edge 25a.

[0118] In another embodiment, the elastic pressing member 22 is bonded to the through hole K2 , for example, by bonding the two side surfaces of the elastic pressing member 22 in the thickness direction and the two pressing edges 26 .

[0119] The two methods of bonding and interference fit between the elastic pressing member 22 and the first side edge 25a can also be used together to further ensure the connection reliability.

[0120] Of course, other connection methods may also be used alone or in combination to connect the elastic pressing member 22 and the first side 25 a , which is not limited here.

[0121] Figure 8 In the illustrated embodiment, the cross section of the elastic pressing member 22 is rectangular. In other embodiments, the elastic pressing member 22 may also be configured to have a cross section of other shapes, such as Fig. 9 and Fig.10 Two different forms are shown.

[0122] See also Fig. 9 , the first side 25a has an insertion surface P1 facing away from the second side 25b, and the through hole K2 is provided on the insertion surface P1, that is, the through hole K2 is recessed from the insertion surface P1 and passes through the first side 25a. The elastic pressing member 22 includes an abutting portion 27 abutting against the insertion surface P1 and an inserting portion 28 connected to the abutting portion 27 and inserted into the through hole K2, and the inserting portion 28 is used to abut against the optical filter 10. In this embodiment, by limiting the abutting portion 27 and the insertion surface P1, it is convenient to judge whether the elastic pressing member 22 is inserted in place, so as to avoid the elastic pressing member 22 being pressed in too much and damaging the optical filter 10 or deforming the optical filter 10.

[0123] Fig.10 Shows that different from Fig. 9 Another embodiment of . Fig.10 , the first side 25a has an insertion surface P1 facing away from the second side 25b, the through hole K2 is provided on the insertion surface P1, and the through hole K2 is formed with a receiving groove C5 at the insertion surface P1, that is, the through hole K2 as a whole is a larger stepped hole close to the insertion surface P1. The elastic pressing member 22 includes an abutting portion 27 provided in the receiving groove C5 and an inserting portion 28 connected to the abutting portion 27 and inserted into the through hole K2, and the inserting portion 28 is used to abut against the filter 10. This embodiment can also prevent the elastic pressing member 22 from being pressed in too much, and the elastic pressing member 22 will not extend out of the through hole K2, thereby avoiding increasing the width dimension (i.e., the dimension along the first direction Y1) of the filter assembly 120.

[0124] In summary, by using the filter mounting frame 20 of the disclosed embodiment, the installation operation of the filter 10 is convenient and quick, and the elastic pressing member 22 is fixed at the through hole K2 of the first side 25a by elastic deformation of the elastic pressing member 22, which can adapt to thermal deformation of the filter 10 and avoid crushing the filter 10.
