Description

Technical Field

[0001] This application relates to the field of skin care technology, and more particularly to a skin care device. Background Technology

[0002] Hair removal devices and skin rejuvenation devices are common skin care equipment used in daily life. These devices primarily use IPL (intense pulsed light) to irradiate the user's skin, thereby achieving effects such as hair removal and skin rejuvenation. Taking a hair removal device as an example, it consists of a housing and an IPL light source. The housing has a light-emitting aperture, and the IPL light source is located inside the housing to generate light that is projected onto the skin through the aperture.

[0003] In related technologies, the IPL light source of skin care devices only includes one lamp tube, which results in the IPL light source having only a single light output state. Ultimately, this makes the skin care mode of the skin care device singular and difficult to meet the diverse skin care needs of users. Utility Model Content

[0071] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the protection scope of this application.

[0072] This application provides a skin care device, which can be a light-based skin care device, such as a hair removal device or a skin rejuvenation device, so that the skin care device has a light-based care function.

[0073] Phototherapy can be performed by irradiating the skin to be treated with IPL light sources, laser light sources, or LED light sources, etc., and this application does not limit this.

[0074] For example, please refer to Figure 1 The skin care device includes a housing 1 and a light-emitting assembly 2. The housing 1 has a light-emitting port 11. The light-emitting assembly 2 is disposed inside the housing 1 and is used to generate light that is emitted from the light-emitting port 11 onto the skin to be treated.

[0075] Of course, skin care devices may also have electrical stimulation functions, making them multifunctional skin care devices with at least phototherapy and electrical stimulation functions. This application does not limit this aspect.

[0076] Electrical stimulation care can be performed by applying electrical stimulation currents such as radiofrequency current, intermediate frequency current, and microcurrents (such as EMS current) to the skin to be treated.

[0077] Of course, the skin care device can also have a cold compress function; thus, during the skin care process, the cold compress function can improve the heat sensation generated when the skin to be treated is irradiated by the light-emitting component 2.

[0078] For example, the skin care device may also include a cooling component 3, which is located at the light outlet 11 for applying a cooling compress to the skin to be treated.

[0079] In some embodiments, the skin care device may also include a heat dissipation component 4 for dissipating heat from the cooling component 3 and / or the light-emitting component 2.

[0080] In some embodiments, the skin care device may further include a circuit board assembly 5 disposed within the housing 1. The circuit board assembly 5 is electrically connected to the light-emitting assembly 2, thereby supplying power to the light-emitting assembly 2 and controlling the light-emitting assembly 2 to emit light.

[0081] Of course, the circuit board assembly 5 can also be electrically connected to the cooling assembly 3 and the heat dissipation assembly 4 respectively. Therefore, the circuit board assembly 5 can provide power to the light-emitting assembly 2, the cooling assembly 3 and the heat dissipation assembly 4, and control the operation of the light-emitting assembly 2, the cooling assembly 3 and the heat dissipation assembly 4.

[0082] The above is an overall introduction to the various parts of the skin care device according to the embodiments of this application. Below, the technical solution of the embodiments of this application will be described in conjunction with the light-emitting component 2.

[0083] Through the inventor's creative research, it was discovered that the light-emitting component 2 can be equipped with only one lamp tube 211 to reduce the manufacturing cost of the skin care device. However, the structure of the light-emitting component 2 with only one lamp tube 211 results in the light-emitting component 2 having only a single light-emitting state, which ultimately makes the skin care mode of the skin care device relatively simple and difficult to meet the diverse skin care needs of users.

[0084] Please continue to refer to this. Figure 2 Based on this, in this embodiment, the light-emitting component 2 includes a light-emitting component 21, which is rotatably disposed within the housing 1. The light-emitting component 21 is positioned corresponding to the light-emitting port 11, so that it generates light that is directed from the light-emitting port 11 onto the skin to be treated. The light-emitting component 21 includes at least two lamps 211. By rotatably disposing the light-emitting component 21 within the housing 1, the at least two lamps 211 can have different light-emitting states; under different light-emitting states, the energy density of the light emitted by the light-emitting component 21 and directed onto the skin to be treated is different. In this way, the skin care device can have more skin care modes, thereby meeting more skin care needs of users, such as allowing users to select different light-emitting states and energy densities according to different care needs, such as achieving high-energy-density skin rejuvenation and low-energy-density hair removal.

[0085] It can be understood that by driving the light-emitting component 21 to rotate, the distance between each lamp tube 211 and the light outlet 11 can be changed, thereby changing the area of ​​the orthographic projection of the light-emitting component 21 on the plane where the light outlet 11 is located, and thus changing the energy density of the light emitted by the light-emitting component 21 directed toward the skin to be treated. As a result, in different light emission states, the area of ​​the orthographic projection of the light-emitting component 21 on the plane where the light outlet 11 is located is different, and the energy density of the light emitted by the light-emitting component 21 directed toward the skin to be treated is different.

[0086] In other words, in this embodiment of the application, by rotating the light-emitting component 21, the light emission state of at least two lamp tubes 211 can be switched, thereby enabling the skin care device to have at least two different skin care modes, which can ultimately meet more skin care needs of users.

[0087] In some embodiments, two lamps 211 are provided. Therefore, using two lamps 211 can satisfy diverse skin care needs while avoiding excessive manufacturing difficulty and cost of the skin care device due to an excessive number of lamps 211. Of course, the number of lamps 211 can also be three, four, five, etc., and this application embodiment does not limit this.

[0088] Please continue to refer to this. Figure 3 , Figure 4 and Figure 5 In some embodiments, at least two lamps 211 can be arranged regularly, such as along a certain direction. In this case, the light emission state includes a first light emission state, a second light emission state, and / or a third light emission state. In the first light emission state, the arrangement direction of at least two lamps 211 is perpendicular to the light emission direction. In the second light emission state, the arrangement direction of at least two lamps 211 is parallel to the light emission direction. In the third light emission state, the angle between the arrangement direction of at least two lamps 211 and the light emission direction is greater than 0 and less than or equal to 45 degrees.

[0089] Therefore, on the plane where the light-emitting port 11 is located, the area of ​​the orthographic projection of the light-emitting component 21 in the first light-emitting state, the second light-emitting state and the third light-emitting state are different, so that the light emission density at the light-emitting port 11 is different when the light-emitting component 21 is in the first light-emitting state, the second light-emitting state and the third light-emitting state respectively, thereby adjusting the energy density at the light-emitting port 11.

[0090] For example, when the skin care device needs to perform skin rejuvenation, it can switch to the second state to increase the energy density at the light outlet 11; when the skin care device needs to remove hair, it can switch to the first state to reduce the energy density at the light outlet 11; the third state can be set to skin rejuvenation mode or hair removal mode as needed.

[0091] In another example, at least two lamp tubes 211 can be arranged in other regular or irregular patterns, such as three lamp tubes 211 arranged in a triangle, such as an isosceles triangle or an equilateral triangle, as long as the area of ​​the orthographic projection of the light-emitting component 21 on the plane where the light outlet 11 is located can be changed to change the energy density of the light generated by the light-emitting component 21 directed toward the skin to be treated.

[0092] In some embodiments, the light-emitting assembly 2 further includes a reflector 22, which is used to reflect part of the light generated by the lamp tube 211 to the light-emitting port 11 to increase the energy density at the light-emitting port 11.

[0093] In some embodiments, the reflector 22 is also electrically connected to the circuit board assembly 5, and the distance between the reflector 22 and the lamp tube 211 is less than a preset distance so that the circuit board assembly 5 can excite the lamp tube 211 through the reflector 22. Furthermore, compared to winding conductive wires around the outer peripheral surface of the lamp tube 211 to excite the lamp tube 211, the embodiments of this application can make the structure of the light assembly 2 simpler, and can avoid the conductive wires from hindering the rotation of the lamp tube 211.

[0094] It is understood that in this example, the distance between each lamp tube 211 of the light-emitting component 21 and the reflector 22 is less than a preset distance in different light-emitting states, so that the circuit board assembly 5 can excite each lamp tube 211 through the reflector 22.

[0095] In some embodiments, the reflector 22 is provided with an arc-shaped groove 221, the opening of which faces the light outlet 11, and the lamp tubes 211 are at least partially disposed in the arc-shaped groove 221, so that the reflector 22 is used to reflect part of the light generated by the lamp tubes 211 to the light outlet 11.

[0096] Please continue to refer to this. Figure 6 Optionally, the reflector cup 22 may also be provided with at least two arc-shaped grooves 221, the openings of which face the light outlet 11. During the rotation of the light-emitting assembly 2, different lamp tubes 211 are always at least partially located within different arc-shaped grooves 221. Furthermore, by having at least two lamp tubes 211 correspond one-to-one with at least two arc-shaped grooves 221, the brightness at the light outlet 11 can be made more uniform.

[0097] Please continue to refer to this. Figure 7 Optionally, the reflector cup 22 is provided with at least two arc-shaped grooves 221, the openings of the arc-shaped grooves 221 facing the light outlet 11. The light emission state includes a fourth light emission state and a fifth light emission state. In the fourth light emission state, different lamp tubes 211 are at least partially located in different arc-shaped grooves 221. In the fifth light emission state, different lamp tubes 211 are located in the same arc-shaped groove 221.

[0098] Please continue to refer to this. Figure 8 In some embodiments, the light-emitting component 21 further includes two adapters 23, with one end of at least two lamp tubes 211 fixed to one adapter 23 and the other end of at least two lamp tubes 211 fixed to another adapter 23, and the two adapters 23 being rotatably mounted inside the housing 1.

[0099] That is to say, one end of all the lamp tubes 211 is fixed to one of the adapters 23, and the other end of all the lamp tubes 211 is fixed to another adapter 23. Thus, they are rotatably installed in the housing 1 through the two adapters 23, so that all the lamp tubes 211 can be rotatably installed in the housing 1, so that the light-emitting component 21 has the advantage of easy assembly.

[0100] Please combine Figure 8 and Figure 9 Before introducing the structure of the adapter 23, let's first give a brief introduction to the circuit board assembly 5.

[0101] The circuit board assembly 5 may include a first circuit board 51 and two conductive supports 52, which are spaced apart and mounted on the first circuit board 51. A light-emitting component 21 is located between the two conductive supports 52, and both ends of the light-emitting component 21 are respectively mounted on the two conductive supports 52, so that the light-emitting component 21 is electrically connected to the first circuit board 51.

[0102] For example, each adapter 23 is rotatably electrically connected to one of the conductive supports 52, thereby at least two lamps 211 are rotatably supported on the first circuit board 51 at least through the adapter 23 and the conductive support 52, so that the at least two lamps 211 have different light emission states. Furthermore, each end of the at least two lamps 211 is electrically connected to the first circuit board 51 through the adapter 23 and the conductive support 52 at its respective end.

[0103] Furthermore, the conductive bracket 52 can provide physical support for the adapter 23 of the light-emitting component 2, and can also supply power to the lamp tube 211 through the adapter 23.

[0104] In some embodiments, the adapter 23 may include a lamp mounting portion 231 and a pivot portion 232. At least two lamps 211 are mounted at one end to the lamp mounting portion 231. The pivot portion 232 protrudes from the side of the lamp mounting portion 231 away from the at least two lamps 211, or in other words, the pivot portion 232 protrudes from the side surface of the lamp mounting portion 231 away from another adapter 23. The pivot portion 232 is rotatably electrically connected to the conductive bracket 52.

[0105] Therefore, both the lamp tube 211 and the lamp tube mounting part 231 are rotatably mounted between the two conductive supports 52. This avoids interference between the lamp tube 211 and the lamp tube mounting part 231 and the conductive supports 52 during rotation.

[0106] In some embodiments, the adapter 23 is a conductive element.

[0107] For example, the conductive component can be a metallic conductive component made of copper, aluminum, or other materials, or a non-metallic conductive component such as conductive silicone. Of course, the conductive component can also be any other composite material conductive component; this application does not limit this. Consequently, the adapter 23 has the advantages of simple structure, ease of production, and low manufacturing cost.

[0108] Optionally, the lamp mounting part 231 is a second circuit board, at least one end of two lamps 211 is electrically connected to the second circuit board, and the rotating part 232 is a conductive component, which is electrically connected to the second circuit board.

[0109] Therefore, according to the actual control requirements, the second circuit board can be equipped with a power distribution circuit, so that the second circuit board can selectively supply power to one or more lamp tubes 211, or output different voltages to different lamp tubes 211, etc., so as to enrich the light-emitting modules of the light-emitting component 21.

[0110] Of course, at least two lamps 211 can also be connected in parallel between the second circuit boards of the two adapters 23, so that the two lamps 211 can be switched on and off synchronously. This application embodiment does not limit this.

[0111] In some embodiments, the axis of rotation of the adapter 23 is located at the midpoint of the line connecting the two farthest lamp tubes 211.

[0112] Correspondingly, the axis of the rotating shaft 232 is located at the midpoint of the line connecting the two farthest lamp tubes 211.

[0113] Therefore, when the light-emitting component 21 rotates around the rotation axis (i.e., the rotating shaft 232) of the adapter 23, the force on each position in the circumferential direction of the rotating shaft 232 is more uniform and reasonable, so as to ensure the stability and reliability of the rotation of the light-emitting component 21.

[0114] For example, at least two lamps 211 are arranged at intervals along a direction perpendicular to the rotation axis of the adapter 23.

[0115] In some embodiments, the lamp tubes 211 are all extended along the direction of the rotation axis of the adapter 23.

[0116] It is understandable that if the lamp tube 211 is perpendicular to the rotation axis of the adapter 23, the area swept by the lamp tube 211 during rotation will be larger, so that a larger space needs to be reserved inside the housing 1 for the end of the lamp tube 211 to move, which is not conducive to the miniaturization design of the skin care device; in contrast, the housing 1 of this application embodiment only needs to reserve a smaller space.

[0117] The above is a description of the adapter 23 in the embodiments of this application. The conductive bracket 52 in the embodiments of this application will be described below.

[0118] In some embodiments, the conductive support 52 includes two opposing clamping portions 521. One end of each clamping portion 521 is fixed to the first circuit board 51, and the other end of each clamping portion 521 forms a clamping space 522 between the two clamping portions 521. The light-emitting component 21 (such as the adapter 23 of the light-emitting component 21) is rotatably disposed within the clamping space 522. Therefore, the two clamping portions 521 can achieve a rotatable connection between the light-emitting component 21 and the conductive support 52.

[0119] In some embodiments, the clamping part 521 is in elastic contact with the adapter 23.

[0120] On the one hand, during the production of skin care equipment, there are inevitably manufacturing tolerances in the conductive support 52 and the adapter 23. Therefore, by making elastic contact between the clamping part 521 and the adapter 23, the manufacturing tolerances of the conductive support 52 and the adapter 23 can be offset, so that the clamping part 521 can fit tightly to the adapter 23. This can prevent the adapter 23 from being unable to rotate stably and reliably in the clamping space 522 formed by the clamping part 521, and also prevent the clamping part 521 and the adapter 23 from failing to form a stable and reliable electrical contact.

[0121] On the other hand, during the later use of the skin care device, as the light-emitting component 21 rotates, both the clamping part 521 and the adapter 23 are prone to wear. Therefore, by making elastic contact between the clamping part 521 and the adapter 23, the wear of the clamping part 521 and the adapter 23 can be offset, so that the clamping part 521 can dynamically and tightly fit the adapter 23. This can prevent the adapter 23 from being unable to rotate stably and reliably in the clamping space 522 formed by the clamping part 521, and can also prevent the clamping part 521 and the adapter 23 from failing to form a stable and reliable electrical contact.

[0122] In some embodiments, the conductive support 52 further includes a connecting portion 523, and the end of the clamping portion 521 near the first circuit board 51 is connected to the connecting portion 523 as a whole, and the connecting portion 523 is fixedly connected to the first circuit board 51.

[0123] Understandably, if the two clamping parts 521 are directly connected to the first circuit board 51, in actual production, the two clamping parts 521 need to be accurately positioned at appropriate locations on the first circuit board 51 so that they can together form the clamping space 522. In contrast, in this embodiment, the installation of the two clamping parts 521 can be completed simply by fixing the connecting part 523 to the first circuit board 51, giving the conductive bracket 52 the advantages of simple structure and easy installation.

[0124] The connecting part 523 can be fixed to the first circuit board 51 by at least one of snap-fit ​​and soldering, which is not limited in this embodiment.

[0125] In some embodiments, the two clamping portions 521 are spaced apart at one end away from the first circuit board 51 to form a mounting port 524, so that the light-emitting component 2 can be inserted between the two clamping portions 521 through the mounting port 524.

[0126] This makes it easy to install the light-emitting component 2 and the conductive support 52.

[0127] In some embodiments, at least one clamping portion 521 has an inclined abutment portion 5211 at its end away from the first circuit board 51, and the inclined abutment portion 5211 extends inclinedly away from the other clamping portion 521 and the first circuit board 51. A clamping space 522 is formed between the inclined abutment portion 5211 and the other clamping portion 521.

[0128] Furthermore, by extending the inclined abutment portion 5211 in an inclined direction away from the other clamping portion 521 and the first circuit board 51, the inclined abutment portion 5211 of the clamping portion 521 is bent and connected to other parts, thereby forming an elastic contact with the rotating shaft portion 232 of the rotating member through the bent clamping portion 521.

[0129] Furthermore, when the inclined support portion 5211 forms a mounting port 524 at one end away from the first circuit board 51, the corresponding end of the light-emitting component 2 can be more easily inserted into the two corresponding clamping portions 521 through the mounting port 524.

[0130] For example, a guide space is formed between the inclined abutment portions 5211 of the two clamping portions 521 to facilitate the insertion of the light-emitting assembly 2 from the mounting port 524 into the clamping space 522 along the guide space.

[0131] In some embodiments, the distance between the end of the inclined abutment 5211 near the first circuit board 51 and the other clamping part 521 is smaller than the diameter of the pivot part 232 of the adapter 23.

[0132] Therefore, taking the first circuit board 51 located below the inclined support portion 5211 as an example, it can be understood that the lower end of the inclined support portion 5211 supports the bottom of the rotating shaft portion 232, so that the inclined support portion 5211 supports the light-emitting component 21 above the first circuit board 51.

[0133] Please continue to refer to this. Figure 10 In some embodiments, at least one of the clamping portions 521 has a clamping groove 525 formed at the end away from the first circuit board 51, which faces the other clamping portion 521, and a clamping space 522 is formed between the clamping groove 525 and the other clamping portion 521. Furthermore, the adapter 23 of the light-emitting component 21 can be installed and fixed through the clamping groove 525.

[0134] Please continue to refer to this. Figure 11 In some embodiments, the clamping portion 521 includes a support extension 5212 and a first bending portion 5213. One end of the support extension 5212 is fixedly connected to the first circuit board 51, and the other end extends in a direction away from the first circuit board 51. One end of the first bending portion 5213 is connected to the other end of the support extension 5212, and the other end of the first bending portion 5213 extends obliquely in a direction closer to another clamping portion 521 and away from the first circuit board 51, so as to form a clamping space 522 between the other end of the clamping portion 521 and the other clamping portion 521.

[0135] Furthermore, by supporting the extension section 5212 and the first bending section 5213, an elastic contact can be formed between the end of the first bending section 5213 away from the supporting extension section 5212 and the adapter 23 of the light-emitting component 21.

[0136] like Figure 9 As shown, in some embodiments, the clamping portion 521 includes a support extension 5212, a first bending section 5213, and an inclined abutment portion 5211. One end of the support extension 5212 is fixedly connected to the first circuit board 51, and the other end extends in a direction away from the first circuit board 51. One end of the first bending section 5213 is connected to the other end of the support extension 5212, and the other end of the first bending section 5213 extends inclinedly in a direction closer to another clamping portion 521 and away from the first circuit board 51. The inclined abutment portion 5211 is connected to the other end of the first bending section 5213. The inclined abutment portion 5211 extends inclinedly in a direction away from the other clamping portion 521 and the first circuit board 51, and a clamping space 522 is formed between the inclined abutment portion 5211 and the other clamping portion 521.

[0137] Therefore, the first bending section 5213 and the inclined supporting part 5211 can form a V-shaped structure that is recessed toward the other clamping part 521, thereby making elastic contact between the clamping part 521 and the light-emitting component 21.

[0138] like Figure 11 As shown, in some embodiments, the clamping portion 521 includes a first bent section 5213, a clamping section 5215, and a second bent section 5214. One end of the first bent section 5213 is fixedly connected to the first circuit board 51. One end of the first bent section 5213 extends obliquely toward the other clamping portion 521 and away from the first circuit board 51. The clamping section 5215 is connected to the other end of the first bent section 5213 and has a clamping groove 525 facing the other clamping portion 521, forming a clamping space 522 between the clamping groove 525 and the other clamping portion 521. The second bent section 5214 is connected to the end of the clamping section 5215 away from the first circuit board 51 and extends obliquely away from the other clamping portion 521 and the first circuit board 51, forming a guide space above the clamping space 522 between the second bent section 5214 and the other clamping portion 521.

[0139] Furthermore, firstly, a V-shaped structure is formed between the first bending section 5213 and the second bending section 5214 by the clamping section 5215, which is recessed toward the other clamping part 521, thereby making elastic contact between the clamping part 521 and the light-emitting component 21; secondly, the clamping section 5215 can install and fix the adapter 23 of the light-emitting component 21 through the clamping groove 525; thirdly, the guide space formed by the second bending section 5214 can also facilitate the light-emitting component 2 to be inserted into the clamping space 522 from the mounting port 524 along the guide space.

[0140] Please continue to refer to this. Figure 12 and Figure 13 In some embodiments, the skin care device further includes a mounting bracket 6, which is disposed within the housing 1 and has an installation space with an opening facing the light outlet 11. The light-emitting component 2 is disposed within the installation space, and the adapter 23 is rotatably mounted on the mounting bracket 6.

[0141] Furthermore, by rotating the adapter 23 onto the mounting bracket 6, the insufficient strength of the conductive bracket 52 can prevent the unreliable installation of the light-emitting component 21.

[0142] For example, the mounting bracket 6 may have a rotating groove 61 or a rotating hole, and the end of the light-emitting component 21 (i.e., the rotating shaft portion 232 of the adapter 23) is rotatably mounted in the rotating groove 61 or the rotating hole.

[0143] Please continue to refer to this. Figure 14 In some embodiments, the skin care device further includes a first drive assembly 7, which is connected to the adapter 23 for driving the light-emitting assembly 21 to rotate.

[0144] For example, the first driving component 7 includes a first power source 71 and a first transmission mechanism 72. The first power source 71 is connected to the light-emitting component 21 through the first transmission mechanism 72 to drive the light-emitting component 21 to rotate.

[0145] Furthermore, the skin care device can accurately and automatically drive the light-emitting component 21 to rotate via the first power source 71.

[0146] The first power source 71 may include an electric motor, such as a servo motor or a stepper motor, but this application embodiment does not limit this.

[0147] The first transmission mechanism 72 may include a connecting shaft, for example, one end of the coupling is connected to the rotating shaft portion 232 of the adapter 23, and the other end of the coupling is connected to the output shaft of the motor.

[0148] Of course, the first transmission mechanism 72 may also include one or more of the following: gear transmission mechanism, sprocket transmission mechanism, belt transmission mechanism, cam transmission mechanism and linkage transmission mechanism. This application embodiment does not limit this.

[0149] Please continue to refer to this. Figure 15 Optionally, the first driving component 7 further includes a first operating component 73 and a first transmission mechanism 72. The first operating component 73 is connected to the light-emitting component 21 via the first transmission mechanism 72. The first operating component 73 is at least partially exposed outside the housing 1. The first operating component 73 is used to accept user operation so as to drive the light-emitting component 21 to rotate via the first transmission mechanism 72.

[0150] Furthermore, the user can manually adjust the light emission state of the light-emitting component 21 through the first operating component 73.

[0151] The first operating component 73 may include buttons, knobs, rings, push rods, and sliders, etc., and this application embodiment does not limit this.

[0152] Please continue to refer to this. Figure 16 The technical solutions of the embodiments of this application will now be described in conjunction with the light output port 11.

[0153] In some examples, a light-transmitting sheet is provided at the light outlet 11, which is exposed outside the housing 1 for contact with the skin. The light-transmitting sheet is provided inside the light outlet 11 or covers the light outlet 11. The thickness of the light-transmitting sheet is greater than or equal to 0.6 mm and less than or equal to 3.5 mm, such as 0.6 mm, 0.8 mm, 1 mm, 1.2 mm, 1.4 mm, 1.6 mm, 1.8 mm, 2 mm, 2.2 mm, 2.4 mm, 2.6 mm, 2.8 mm, or 3 mm.

[0154] In this way, the light emitted by the light-emitting component 2 can be directed onto the skin to be treated through the light-transmitting sheet. By setting the light-transmitting sheet to 0.6 mm-3 mm, or optionally 0.8 mm-2.3 mm, the light emitted by the light-emitting component can be initially mixed and then directed onto the skin to be treated, thereby forming different effective light-emitting areas according to different light-emitting states.

[0155] Among them, the effective light-emitting area refers to the light-emitting area with a higher light density, which is related to the area formed by the light-emitting component 21 under different light-emitting states.

[0156] In this example, when the skin care device needs to perform skin rejuvenation, it can switch to the second or third state to increase the energy density at the light outlet 11, but the effective light emission area is smaller; when the skin care device needs to remove hair, it can switch to the first state to reduce the energy density at the light outlet 11, but the effective light emission area is larger.

[0157] In other embodiments, the size of the light outlet 11 is adjustable. Furthermore, by adjusting the size of the light outlet 11, the light-emitting area of ​​the skin care device can be adjusted, allowing the skin care device to meet more of the user's skin care needs.

[0158] In some implementations, different light emission states correspond to different sizes of light emission ports 11. This allows the size of the light emission port 11 to match different light emission states, which can adapt the effective light emission area to the light emission port 11, thereby making the light in the light emission port 11 more uniform and improving the user experience.

[0159] In some implementations, such as Figure 16 As shown, the housing 1 includes a main body 12 and a floating part 13. The floating part 13 is movably mounted on the main body 12 and defines at least a portion of the boundary of the light outlet 11.

[0160] Furthermore, the size of the light outlet 11 can be adjusted by the movement of the floating part 13.

[0161] In some embodiments, the cold compress assembly 3 includes a cold compress member 31, which is disposed at the light outlet 11 for applying a cold compress to the skin to be treated. The cold compress member 31 can also be rotatably mounted on the housing 1. The cold compress member 31 can be rotated to different angles to push the floating part 13 to different positions, thereby adjusting the size of the light outlet 11.

[0162] For example, the cooling compress 31 has a cuboid structure, thus having a length direction, a width direction, and a thickness direction. The two ends of the cooling compress 31 along its length direction are rotatably mounted on the main body 12. The cooling compress 31 can rotate to a first angle and a second angle. When the cooling compress 31 rotates to the first angle, one surface of the cooling compress 31 along its thickness direction faces the light-emitting assembly 2, and one surface along its width direction abuts against the floating part 13; when the cooling compress 31 rotates to the second angle, one surface of the cooling compress 31 along its thickness direction abuts against the floating part 13, and one surface along its width direction faces the light-emitting assembly 2. Furthermore, the cooling compress 31 can be rotated so that one surface along its thickness direction or one surface along its width direction abuts against the floating part 13 to push the floating part 13 to different positions, thereby adjusting the size of the light-emitting port 11.

[0163] In some embodiments, the cooling patch 31 is a light-transmitting component, such as sapphire.

[0164] Understandably, as the cooling compress 31 rotates to the first or second angle, the dimensions of the cooling compress 31 in the light emission direction will also change, and consequently the mixing distance of the light generated by the light emission component 2 within the cooling compress 31 will also change, thereby adjusting the light emission mode of the skin care device.

[0165] For example, when the size of the cooling compress 31 in the light-emitting direction increases, the light mixing distance within the cooling compress 31 also increases, thereby making the energy density of each area at the light outlet 11 more uniform; when the size of the cooling compress 31 in the light-emitting direction decreases, the light mixing distance within the cooling compress 31 also decreases, thereby making the energy density at the center of the light outlet 11 higher, and thus making the light at the center of the light outlet 11 more suitable for skin rejuvenation.

[0166] It should also be noted that either the cold compress 31 or the housing 1 may have a rotating shaft and the other may have a rotating hole, with the rotating shaft rotatably disposed in the rotating hole so that the cold compress 31 may be rotatably mounted on the housing 1; or the cold compress 31 may be rotatably mounted on the housing 1 via a cold compress bracket. This embodiment of the application does not limit this.

[0167] In some embodiments, the skin care device further includes an elastic element 14, which is elastically connected to the floating part 13. The elastic element 14 is used to push the floating part 13 against the cold compress 31, so that the floating part 13 can fit tightly against the cold compress 31.

[0168] Please continue to refer to this. Figure 17 In some embodiments, the skin care device further includes a light filter assembly 8. The light filter assembly 8 is used to filter the light emitted by the light emitting assembly 2 toward the light emitting port 11.

[0169] The light filter assembly 8 can have at least two different filtering modes, and the light filter assembly 8 filters different light rays emitted from the light-emitting component 21 towards the light outlet 11 in different filtering modes. Therefore, through the different filtering modes of the light filter assembly 8, the skin care device can meet more of the user's skin care needs.

[0170] In some implementations, different light emission states correspond to different filtering modes.

[0171] In some embodiments, the light filtering assembly 8 includes a first filter 811, a second filter 812, a second power source 813, and a second transmission mechanism 814. The first filter 811 is fixedly disposed between the light emitting assembly 2 and the light emitting port 11 to filter the light emitted from the light emitting assembly 2 towards the light emitting port 11. The second power source 813 is connected to the second filter 812 via the second transmission mechanism 814. The second power source 813 drives the second filter 812 to move between a filtering position and a reversing position. When the second filter 812 is in the filtering position, it filters the light emitted from the light emitting assembly 2 towards the light emitting port 11. When the second filter 812 is in the reversing position, it reverses the light emitted from the light emitting assembly 2 towards the light emitting port 11.

[0172] Furthermore, the filter assembly 8 can be driven by the second power source 813 to move the second filter 812, so that the filter assembly 8 can filter light by passing through the first filter 811 alone, or by passing through the first filter 811 and the second filter 812 simultaneously.

[0173] The second power source 813 may include a motor, such as a servo motor or a stepper motor, but this application embodiment does not limit this.

[0174] The second transmission mechanism 814 may also include one or more of the following: gear transmission mechanism, sprocket transmission mechanism, belt transmission mechanism, cam transmission mechanism, and linkage transmission mechanism. This application embodiment does not limit this.

[0175] Please continue to refer to this. Figure 18 Optionally, the light filtering assembly 8 may include a first filter 811, a second filter 812, a second transmission mechanism 814, and a second operating component 815. The first filter 811 is fixedly disposed between the light emitting assembly 2 and the light emitting port 11 to filter the light emitted from the light emitting assembly 2 toward the light emitting port 11. The second operating component 815 is connected to the second filter 812 via the second transmission mechanism 814. The second operating component 815 is used to accept user operation to drive the second filter 812 to move between a filtering position and a reversing position. When the second filter 812 is in the filtering position, it filters the light emitted from the light emitting assembly 2 toward the light emitting port 11. When the second filter 812 is in the reversing position, it reverses the light emitted from the light emitting assembly 2 toward the light emitting port 11.

[0176] Furthermore, the user can manually drive the second filter 812 to move so that the filter assembly 8 filters light by passing through the first filter 811 alone, or by passing through the first filter 811 and the second filter 812 simultaneously.

[0177] The second operating component 815 may include buttons, knobs, rings, push rods, and sliders, etc., which are not limited in this application embodiment.

[0178] Please continue to refer to this. Figure 19 Optionally, the filter assembly 8 includes a second power source 813, a second transmission mechanism 814, and at least two filters 81. The second power source 813 is connected to at least two filters 81 via the second transmission mechanism 814. The second power source 813 is used to selectively drive at least one of the filters 81 to move between the light-emitting assembly 2 and the light-emitting port 11.

[0179] Furthermore, the filter assembly 8 can be driven by the second power source 813 to move different filters 81 between the light-emitting assembly 2 and the light-emitting port 11 for filtering, thereby enabling the filter assembly 8 to be in different filtering modes.

[0180] For example, the second power source 813 can drive multiple different filters 81 to rotate, so that one of the filters 81 can be moved between the light-emitting assembly 2 and the light-emitting port 11 for filtering.

[0181] Please continue to refer to this. Figure 20 Optionally, the filter assembly 8 further includes a second operating component 815, a second transmission mechanism 814, and at least two filters 81. The second operating component 815 is connected to at least two filters 81 via the second transmission mechanism 814. The second operating component 815 is used to accept user operation to selectively drive at least one of the filters 81 to move between the light-emitting assembly 2 and the light-emitting port 11 to filter the light emitted from the light-emitting assembly 2 toward the light-emitting port 11.

[0182] Furthermore, the user can manually drive different filters 81 to move between the light-emitting component 2 and the light-emitting port 11 for filtering, thereby putting the filter component 8 into different filtering modes.

[0183] Optionally, the filter assembly 8 also includes an adjustable light-transmitting element, which is disposed between the light-emitting assembly 2 and the light-emitting port 11, and at least one of the color and light transmittance of the adjustable light-transmitting element is adjustable.

[0184] For example, adjustable light-transmitting components may include color-changing films, electrochromic components, etc., and the embodiments of this application do not limit this.

[0185] Please continue to refer to this. Figure 21In some embodiments, the heat dissipation component 4 is disposed inside the housing 1. The heat dissipation component 4 includes a heat-conducting element 41, a heat sink 42 and a fan 43. The heat-conducting element 41 is thermally connected to the cooling component 3. The heat sink 42 is disposed on the heat-conducting element 41. The fan 43 is used to drive gas to flow through the heat sink 42 to dissipate heat from the cooling component 3.

[0186] For example, the cooling assembly 3 may include a cooling element 31 and a cooling pad 32. The cooling element 31 is disposed at the light outlet 11, the cold side of the cooling pad 32 is thermally connected to the cooling element 31, and the hot side of the cooling pad 32 is thermally connected to the heat-conducting element 41. Furthermore, the heat from the cooling pad 32 can be transferred to the heat sink 42 through the heat-conducting element 41, and the fan 43 drives gas to flow through the heat sink 42 to dissipate heat from the cooling assembly 3. This improves the cooling effect of the cooling assembly 3.

[0187] In some embodiments, the heat-conducting component 41 includes at least one of a heat spreader and a copper pipe, thereby enabling the heat-conducting component 41 to quickly transfer the heat from the cooling assembly 3 to the heat sink 42, thereby improving the heat dissipation effect of the heat dissipation assembly 4.

[0188] In some embodiments, the air outlet of the fan 43 faces the heat sink 42 so that the air flowing out of the fan 43 can be blown toward the heat sink 42.
