[0055] 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.

[0056] 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.

[0057] Example

[0058] See also Figure 1 This embodiment provides a skin treatment device 1000, which can be a hair removal device, a skin rejuvenation device, a hair growth device or other skin treatment devices 1000. 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.

[0059] See also Figure 2 In this embodiment, the skin treatment device 1000 includes a housing 12 , a light-transmitting bracket 15 , a light-transmitting member 26 and a filter 25 .

[0060] The housing 12 has an internal space Q1 and a light outlet K1 , and the light outlet K1 is connected to the internal space Q1 . The light-transmitting bracket 15 is installed in the internal space Q1 of the housing 12 , and is used to install the light-transmitting member 26 and the filter 25 .

[0061] The skin treatment device 1000 in this embodiment may further include a light source 22 and a reflective cup 24, which are respectively installed in the housing 12. The light emitted by the light source 22 is focused by the reflective cup 24 and then emitted to the filter 25. After being filtered by the filter 25, the light is emitted from the light-transmitting member 26 outside the housing 12 along the light-emitting direction X to obtain treatment light for skin treatment. 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.

[0062] 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.

[0063] 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.

[0064] The light source 22 is used to generate light. In this embodiment, the light source 22 is a lamp tube 23 .

[0065] 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 1000; for example, the lamp tube 23 can be an LED lamp tube 23, and so on.

[0066] 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: 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 tube 23 to instantly release a strong pulse of light, thereby completing one light emission.

[0067] 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 22, etc., which is not limited here.

[0068] Continue to see Figure 2 The light-transmitting bracket 15 is installed in the internal space Q1 of the housing 12. 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.

[0069] In this embodiment, one end of the light-transmitting member 26 is mounted on the light-transmitting bracket 15 , and the other end thereof extends into the light outlet K1 matched with the front shell 21 of the housing 12 .

[0070] 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.

[0071] In this embodiment, the filter 25 is mounted on the light-transmitting bracket 15 and is located between the light-transmitting member 26 and the light source 22 .

[0072] The filter 25 can filter the light emitted by the light source 22 to select the light of the required wavelength for emission. There can be one or more filters 25 to achieve a combined filtering effect.

[0073] See also Figure 3 and Figure 4 The light-transmitting bracket 15 of this embodiment includes a mounting bracket 41 and a pressing member 42 .

[0074] See also Figure 4 and Figure 5 The mounting bracket 41 has a mounting space Q2, which passes through the mounting bracket 41 along the light emitting direction X of the skin treatment device 1000. The mounting bracket 41 is provided with a first through hole K3 and a second through hole K4, which are spaced apart along the light emitting direction X.

[0075] The light-transmitting member 26 is at least partially installed in the installation space Q2. Figure 4 As shown in FIG. 1 , the light-transmitting member 26 is partially installed in the installation space Q2, and partially extends from the installation space Q2 and matches the front shell 21 of the housing 12. In this way, the front end surface of the light-transmitting member 26 can be exposed outside the housing 12 for contacting the user's skin to achieve an ice compress effect.

[0076] The filter 25 is installed in the installation space Q2 and is located on one side of the light-transmitting member 26 along the light-emitting direction X.

[0077] See also Figure 6 The pressing member 42 includes an annular portion 43, a first pressing protrusion 44 and a second pressing protrusion 45, the first pressing protrusion 44 is connected to the inner circumference of the annular portion 43, the second pressing protrusion 45 is connected to the inner circumference of the annular portion 43 and is spaced from the first pressing protrusion 44 along the light emitting direction X; the annular portion 43 is sleeved on the outer circumference of the mounting bracket 41, the first pressing protrusion 44 passes through the first through hole K3 and presses against the outer circumference of the light transmitting member 26, and the second pressing protrusion 45 passes through the second through hole K4 and presses against the outer circumference of the filter 25.

[0078] In the skin treatment device 1000 of this embodiment, the light-transmitting member 26 and the filter 25 can be assembled together on the mounting bracket 41 and pressed and positioned by the pressing member 42, so that the assembly is convenient and the relative position accuracy of the light-transmitting member 26 and the filter 25 can be easily guaranteed.

[0079] Continue to see Figures 3 to 5 In this embodiment, an annular groove C1 is provided on the outer circumferential surface of the mounting bracket 41, and the first through hole K3 is recessed from the groove bottom surface of the annular groove C1, and the second through hole K4 is recessed from the groove bottom surface of the annular groove C1. The annular portion 43 is matched with the annular groove C1, and the annular portion 43 closes the first through hole K3 and the second through hole K4. In this way, the annular portion 43 closes the first through hole K3 and the second through hole K4, which can prevent the first through hole K3 and the second through hole K4 from leaking light or entering dust. Optionally, the thickness of the annular portion 43 is equal to the depth of the annular groove C1, and the two sides of the annular portion 43 along the light emitting direction X respectively abut against the groove surfaces on both sides of the annular groove C1 along the light emitting direction X. In this way, it can be ensured that the outer surface of the annular portion 43 is flush with the outer circumferential surface of the mounting bracket 41, so that the annular portion 43 and the mounting bracket 41 are conveniently installed and matched as a whole in the housing 12.

[0080] In this embodiment, the light-transmitting member 26 and the filter 25 are spaced apart from each other along the light-emitting direction X, and there is a spacing space Q3 (see FIG. Figure 4 ). The first pressing protrusion 44 and the second pressing protrusion 45 are made of elastic material, the first pressing protrusion 44 elastically seals and presses the outer peripheral surface of the light-transmitting member 26, and the second pressing protrusion 45 elastically seals and presses the outer peripheral surface of the filter 25. In this way, through the sealing and pressing of the first pressing protrusion 44 and the light-transmitting member 26, and the sealing and pressing of the second pressing protrusion 45 and the filter 25, the sealing of the interval space Q3 between the light-transmitting member 26 and the filter 25 can be improved, so that the interval space Q3 is not easy to enter water vapor condensation or dust. Optionally, the annular portion 43, the first pressing protrusion 44 and the second pressing protrusion 45 are integrally formed of an elastic material to obtain a clamping member 42, for example, the molding material of the clamping member 42 is silicone. In this way, when the clamping member 42 needs to be installed on the mounting bracket 41, the annular portion 43 of the clamping member 42 can undergo a certain deformation so that the annular portion 43 can be inserted and fitted into the annular groove C1 of the mounting bracket 41.

[0081] In this embodiment, the inner circumference of the mounting bracket 41 is concavely provided with two opposite matching grooves C2 (see Figure 5), a group of opposite sides of the filter 25 are respectively matched with the two matching grooves C2. The matching grooves C2 are provided to ensure that the position of the filter 25 is determined, and to avoid relative displacement between the filter 25 and the mounting bracket 41 and affect the filtering effect. The two matching grooves C2 shown in the figure are located at the upper and lower long sides of the mounting bracket 41, and are used to match the two long sides of the filter 25. In other embodiments, the matching grooves C2 can also be provided at the short sides of the mounting bracket 41. Optionally, in this embodiment, the portion of the second through hole K4 corresponding to the matching groove C2 passes through from the outer peripheral surface of the mounting bracket 41 to the groove bottom surface of the matching groove C2, that is, the second through hole K4 is connected to the matching groove C2. The second pressing protrusion 45 is accommodated in the second through hole K4, and presses against the portion of the filter 25 placed in the matching groove C2, so that the second pressing protrusion 45 limits the displacement of the filter 25 relative to the mounting bracket 41.

[0082] In this embodiment, optionally, the outer circumferential surface of the light-transmitting member 26 is fitted into the inner circumferential surface of the mounting bracket 41, and the first pressing protrusion 44 is accommodated in the first through hole K3 and extends into and presses against the outer circumferential surface of the light-transmitting member 26 to fix the light-transmitting member 26 and reduce the possibility of relative displacement between the light-transmitting member 26 and the light-transmitting bracket 15.

[0083] In addition, the first pressing protrusion 44 and the second pressing protrusion 45 are respectively accommodated in the first through hole K3 and the second through hole K4, and neither of them extends into the inner side of the inner circumferential surface of the light-transmitting member 26, thereby avoiding blocking the light-emitting area of ​​the filter 25 and the light-transmitting member 26, ensuring a larger light-emitting area and improving the light-emitting efficiency.

[0084] Continue to see Figures 4 to 6 In this embodiment, the cross section of the light-transmitting member 26 in a plane perpendicular to the light-emitting direction X is rectangular. The mounting bracket 41 is a rectangular cylindrical structure, with four first through holes K3, which are respectively arranged at the four corners of the mounting bracket 41; with four second through holes K4, which are respectively arranged at the four corners of the mounting bracket 41. The annular portion 43 is a rectangular annular structure, with four first pressing protrusions 44, which are respectively arranged at the four corners of the inner circumference of the annular portion 43; with four second pressing protrusions 45, which are respectively arranged at the four corners of the inner circumference of the annular portion 43. The first pressing protrusions 44 and the second pressing protrusions 45 arranged at the four corners can evenly and reliably fix the light-transmitting member 26 and the filter 25, ensuring that the relative positions of the light-transmitting member 26 and the filter 25 and the mounting bracket 41 are fixed and not easily changed.

[0085] Optionally, the first through hole K3 includes two first hole segments K5, the two first hole segments K5 are respectively located on a group of adjacent edges of the mounting bracket 41, and the two first hole segments K5 are connected to form an L shape at the intersection angle of the adjacent edges. The second through hole K4 includes two second hole segments K6, the two second hole segments K6 are respectively located on a group of adjacent edges of the mounting bracket 41, and the two second hole segments K6 are connected to form an L shape at the intersection angle of the adjacent edges. The first pressing protrusion 44 includes two first pressing strips 46, the two first pressing strips 46 are respectively located on a group of adjacent edges of the inner circumference of the annular portion 43, and the two first pressing strips 46 are connected to form an L shape at the intersection angle of the adjacent edges. The second pressing protrusion 45 includes two second pressing strips 47, the two second pressing strips 47 are respectively located on a group of adjacent edges of the inner circumference of the annular portion 43, and the two second pressing strips 47 are connected to form an L shape at the intersection angle of the adjacent edges. In this way, each first pressing protrusion 44 can press against two adjacent surfaces of the light-transmitting member 26, so that the position of the light-transmitting member 26 relative to the mounting bracket 41 is further fixed; each second pressing protrusion 45 can press against two adjacent surfaces of the filter 25, so that the position of the filter 25 relative to the mounting bracket 41 is further fixed.
