[0063] The realization of the object, functional features and advantages of the present utility model will be further described with reference to the embodiments and the accompanying drawings. Specific embodiments

[0064] Next, the solutions in the embodiments of the present utility model will be clearly and completely described with reference to the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0065] It should be noted that all directional indications (such as up, down, left, right, front, back...) in the embodiments of the present utility model are only used to explain the relative positional relationship and movement conditions between components in a certain specific posture (as shown in the attached drawings). If this specific posture changes, then the directional indications will also change accordingly.

[0066] It should also be noted that when an element is referred to as being "fixed to" or "disposed on" another element, it can be directly on the other element or there may be an intermediate element present at the same time. When an element is referred to as being "connected" to another element, it can be directly connected to the other element or there may be an intermediate element present at the same time.

[0067] In addition, the descriptions involving "first", "second", etc. in the present utility model are only for descriptive purposes and cannot be understood as indicating or implying their relative importance or implicitly specifying the quantity of the indicated technical features. Thus, the features defined with "first" and "second" may explicitly or implicitly include at least one of such features. In addition, the technical solutions between various embodiments can be combined with each other, but it must be based on the fact that those skilled in the art can implement them. When the combination of technical solutions results in contradictions or cannot be implemented, it should be considered that such a combination of technical solutions does not exist and is not within the protection scope required by the present utility model.

[0068] The filter seal proposed in the embodiments of the present utility model is applicable to a variety of skin care devices, such as hair removal devices, beauty instruments, etc. In these devices, the filter is used to filter specific wavelengths of the light source to achieve a more precise skin care effect. However, when installing the filter, a seal is required to ensure that the filter is stably fixed and prevent light leakage. In the traditional technology, the filter and the seal are installed separately, and during the assembly process, the filter and the seal are prone to relative displacement or even falling off, resulting in installation failure or the need for reinstallation, thus affecting the assembly efficiency and effect. Therefore, the embodiments of the present utility model propose a filter seal. First, the filter is fixed on the filter seal so that the two cooperate stably, and then the two are installed together during installation to avoid falling off. For details, reference can be made to Figure 1 and Figure 2 and Figure 3 , Figure 1 which is a schematic structural diagram of the filter seal in an embodiment of the present utility model, Figure 2 is Figure 1 a partial enlarged view of part A in Figure 3 and is a schematic structural diagram of the combination of the filter seal and the filter in an embodiment of the present utility model.

[0069] The embodiments of the present utility model propose a filter seal 10 for sealing the filter 203 of a skin care device 20. The filter seal 10 includes:

[0070] The housing 100 includes a first end face 110, a second end face 120, and a light-transmitting hole 111. The first end face 110 and the second end face 120 are spaced apart and disposed opposite to each other. The light-transmitting hole 111 extends through the middle of the first end face 110 to the middle of the second end face 120. The first end face 110 is used to place the filter 203, and the filter 203 is at least partially opposite to the light-transmitting hole 111.

[0071] The elastic limiting structure 130 is disposed at a part of the first end face 110 and distributed around the light-transmitting hole 111, and the elastic limiting structure 130 and the first end face 110 enclose a clamping space 135 for clamping and fixing the filter 203.

[0072] In this embodiment, the filter seal 10 includes the housing 100 and the elastic limiting structure 130. The housing 100 has a first end face 110, a second end face 120, and a light-transmitting hole 111, wherein the first end face 110 and the second end face 120 are disposed opposite to each other. The light-transmitting hole 111 is formed by machining in the middle of the housing 100. Specifically, high-precision drilling, laser cutting or integral molding can be used to extend through the middle of the first end face 110 to the middle of the second end face 120 to ensure the accuracy of the aperture and the effective transmission of light. The first end face 110 is used to place the filter 203, and the filter 203 is at least partially opposite to the light-transmitting hole 111 to ensure that light can pass through smoothly.

[0073] The elastic limiting structure 130 is disposed at a partial position of the first end face 110 and surrounds the periphery of the light-transmitting hole 111. The elastic limiting structure 130 and the first end face 110 enclose a clamping space 135 for clamping and fixing the filter 203. The housing 100 can be made of an elastic material. In this way, when an external force is applied by the user, the housing 100 and the elastic limiting structure 130 will deform, so as to facilitate the insertion of the filter 203, make the filter 203 opposite to the light-transmitting hole 111, and ensure the effective transmission of light.

[0074] Continue to refer to Figure 1 、 Figure 3, During the installation process, first place the filter 203 on the first end face 110 of the housing 100, such that at least a portion of the filter 203 faces the light-transmitting hole 111. The user manually applies an external force, causing the housing 100 and its elastic limiting structure 130 to undergo slight deformation, and slowly presses the filter 203 into the clamping space 135. At this time, the elastic limiting structure 130 expands outward under the action of the external force, providing sufficient insertion space for the filter 203. When the filter 203 completely enters the clamping space 135 and faces the light-transmitting hole 111, the user gradually releases the external force, and the elastic limiting structure 130 immediately returns to its initial state, thereby tightly clamping the filter 203 and stably fixing it on the first end face 110, ensuring the stability of the filter 203 after installation and avoiding affecting the light transmission effect due to loosening or displacement. At the same time, the restoring force of the elastic limiting structure 130 enables the filter 203 to maintain an accurate position and is not prone to displacement or dropping.

[0075] In summary, during the assembly process, the filter 203 is placed on the first end face 110 and clamped and fixed by the elastic limiting structure 130 to achieve effective limiting. This structural design can effectively prevent the filter 203 from being displaced or dropped during the assembly process, thereby improving the assembly efficiency and accuracy. In addition, this design simplifies the assembly process of the filter 203 and the seal, reducing the assembly time and cost.

[0076] Continue to refer to Figure 2 , In this embodiment, the elastic limiting structure 130 includes at least one first elastic bump 131 disposed along the edge of the first end face 110, and the first elastic bump 131 includes:

[0077] A first limiting portion 132, the first limiting portion 132 protruding from the edge of the first end face 110 and extending in a direction away from the first end face 110 for restricting the filter 203 from slipping off the edge of the first end face 110;

[0078] A second limiting portion 133, the second limiting portion 133 being connected to the first limiting portion 132, and the second limiting portion 133, the first limiting portion 132, and the first end face 110 enclose a clamping space 135 for the filter 203 to be inserted.

[0079] In this embodiment, the first limiting portion 132 protrudes from the edge of the first end face 110 of the housing 100 and extends in a direction away from the first end face 110 (the vertical direction relative to the first end face 110). Its main function is to restrict the movement of the filter 203 in the horizontal direction relative to the first end face 110, thereby preventing the filter 203 from slipping off the edge of the first end face 110 due to horizontal sliding during the assembly process.

[0080] The second limiting portion 133 is connected to the first limiting portion 132, and together with the first limiting portion 132 and the first end face 110, they enclose a clamping space 135. This clamping space 135 is used to insert the filter 203 and limit the filter 203. The function of the second limiting portion 133 is to limit the movement of the filter 203 in the vertical direction relative to the first end face 110, ensuring that the filter 203 will not have a vertical displacement due to gravity or other external forces after the assembly is completed.

[0081] Through the cooperation of the first limiting portion 132 and the second limiting portion 133, the filter 203 can be effectively fixed in both the horizontal and vertical directions after installation. The first limiting portion 132 mainly prevents the filter 203 from slipping horizontally, while the second limiting portion 133 restricts the vertical displacement of the filter 203, enabling the filter 203 to be firmly held in the clamping space 135, ensuring the effectiveness of light transmission and the reliability of the assembly.

[0082] Refer to Figure 5 , Figure 5 which is the top view of the filter seal in an embodiment of the present utility model.

[0083] In this embodiment, the first end face 110 is polygonal;

[0084] The elastic limiting structure 130 includes at least two first elastic bumps 131 spaced apart along the edge of the first end face 110, and the at least two first elastic bumps 131 are respectively distributed at the corner edges and / or the straight-edge edges of the first end face 110.

[0085] In this embodiment, the first end face 110 is polygonal, such as rectangular, square or other geometric shapes with sides (such as circular). According to specific application requirements, the first elastic bumps 131 can be arranged in various ways to ensure the stable installation of the filter 203.

[0086] In the first arrangement, when the first end face 110 is polygonal, such as rectangular or square, one first elastic bump 131 is provided on each of two opposite sides. This arrangement enables the filter 203 to be effectively limited in both the horizontal and vertical directions, ensuring the stability of the filter 203 during the assembly process.

[0087] When the first end face 110 is circular, the first elastic bumps 131 can be arranged on two sides of the axis of symmetry, that is, one first elastic bump 131 is provided at each of two symmetric positions along the circular end face. This arrangement can also effectively fix the filter 203 on the circular end face.

[0088] In the second arrangement, when the first end face 110 is rectangular or square, the first elastic bumps 131 are respectively distributed at the corner edges of the first end face 110. By arranging the first elastic bumps 131 at each corner, it is possible to better limit the filter 203 in multiple directions and ensure that it does not loosen or displace in the corner area. This arrangement is particularly suitable for application scenarios that require higher stability.

[0089] In the third arrangement, the first elastic bumps 131 are provided on both sides of the axis of symmetry of the first end face 110 and at the corner edges of the first end face 110. By arranging the first elastic bumps 131 on both sides of the axis of symmetry and at the corners simultaneously, a more comprehensive limiting effect can be achieved. This arrangement is applicable to situations where the filter 203 needs to be completely stable after installation and not displaced by external forces, and has higher stability and reliability.

[0090] Continue to refer to Figure 5 , the arrangement of the first elastic bumps 131 in this embodiment realizes effective limiting and fixing of the filter 203 through various different configuration methods. Whether it is the arrangement of opposite sides, the arrangement at the corners, or the arrangement combining the axis of symmetry and the corner edges, it can ensure the stability of the filter 203 during the installation process according to different end face shapes and application requirements, and avoid loosening and falling.

[0091] In this embodiment, the first end face 110 may include four edges connected end to end, namely the first edge 110a, the second edge 110b, the third edge 110c, and the fourth edge 110d. By different corner arrangement schemes, the stability of the filter 203 during assembly and use is ensured, and flexible design options are provided to adapt to different application requirements.

[0092] In this embodiment, the first end face 110 includes the first edge 110a, the second edge 110b, the third edge 110c, and the fourth edge 110d connected end to end, where:

[0093] A first elastic bump 131 is respectively provided at each of the four corners formed by the first edge 110a, the second edge 110b, the third edge 110c, and the fourth edge 110d; or,

[0094] A first elastic bump 131 is respectively provided at each of the two diagonally arranged corners among the four corners formed by the first edge 110a, the second edge 110b, the third edge 110c, and the fourth edge 110d; or,

[0095] Three of the four corners formed by the first edge 110a, the second edge 110b, the third edge 110c, and the fourth edge 110d are respectively provided with a first elastic bump 131.

[0096] In this embodiment, the first end face 110 is formed by connecting the first edge 110a, the second edge 110b, the third edge 110c, and the fourth edge 110d end to end to form a quadrilateral structure, generating four corners. The arrangement of the first elastic bumps 131 can be configured according to different stability requirements, specifically including the following three methods:

[0097] In the first arrangement method, a first elastic bump 131 is respectively provided at each of the four corners. This design provides a fixing effect at each corner, ensuring that the filter 203 can be fully limited in both the horizontal and vertical directions after assembly, thereby achieving the optimal stability. This arrangement method is suitable for application scenarios that require the highest reliability and stability, avoiding displacement or loosening of the filter 203 due to any external force.

[0098] In the second arrangement method, a first elastic bump 131 is respectively provided at two diagonally arranged corners among the four corners. This arrangement method provides sufficient limiting effect for the filter 203 while reducing the number of elastic bumps to optimize the use of structure and materials. The diagonal arrangement method can effectively prevent the filter 203 from slipping in the horizontal or diagonal direction during installation, and is suitable for application scenarios that require a certain degree of stability but do not require full four-point fixation.

[0099] In the third arrangement method, a first elastic bump 131 is respectively provided at three of the four corners. This design method can provide a relatively flexible limiting effect on the premise of ensuring the stability of the filter 203. By providing elastic bumps at three corners, it is possible to avoid accidental loosening and slipping of the filter 203 during the assembly process, while leaving a corner without an elastic bump to adapt to special installation requirements. This method is suitable for applications that require flexible adjustment of the fixing points, especially in cases where a larger space is required in some areas or it is convenient for operation.

[0100] The three different corner arrangement methods in this embodiment realize flexible limiting and fixing of the filter 203 during the installation process by different configurations of the first elastic bumps 131 at the four corners. The method of arranging bumps at all four corners can achieve the highest stability; the method of arranging bumps diagonally optimizes the simplicity of the structure and provides a basic limiting effect at the same time; the method of arranging bumps at three corners takes into account both stability and installation flexibility, and is suitable for application scenarios with specific operation requirements.

[0101] Continue to refer toFigure 2 , in this embodiment, the first limiting portion 132 includes a first side wall 132a and a second side wall 132b. The first side wall 132a and the second side wall 132b are respectively connected to two edges at the corner of the first end face 110, and the first side wall 132a and the second side wall 132b are used to abut against the corners of the filter 203.

[0102] In this embodiment, the first limiting portion 132 is composed of the first side wall 132a and the second side wall 132b. Specifically, the first side wall 132a and the second side wall 132b are located at the corner of the first end face 110 and are respectively connected to two adjacent edges at this corner. The first side wall 132a and the second side wall 132b are perpendicular to each other or form a certain angle, so as to better limit the corners of the filter 203. In this way, when the filter 203 is installed, its corners will abut against the first side wall 132a and the second side wall 132b to form a stable limiting structure.

[0103] During the installation process of the filter 203, the corners of the filter 203 are first inserted into the limiting space enclosed by the first side wall 132a and the second side wall 132b. Since the first side wall 132a and the second side wall 132b are respectively connected to two edges at the corner of the first end face 110, the filter 203 will abut against the two side walls when inserted, thereby realizing the limiting of the corners. This design can ensure that the filter 203 remains in the correct position after assembly and will not move in the horizontal or vertical direction due to external factors.

[0104] In addition, the setting of the first side wall 132a and the second side wall 132b can also adapt to slight errors in the corners of the filter 203, so that the filter 203 can enter the limiting space more smoothly during installation. This design improves the installation efficiency of the filter 203 and reduces the time waste and cost increase caused by difficult assembly.

[0105] Furthermore, the ends of the first side wall 132a and the second side wall 132b facing away from the first end face 110 extend in a direction away from the first end face 110.

[0106] In this embodiment, the ends of the first side wall 132a and the second side wall 132b facing away from the first end face 110 both extend in a direction away from the first end face 110. The extension length is designed according to the thickness of the filter 203, so that when the filter 203 is inserted into the limiting space, the extended portions of the side walls can provide sufficient supporting force to clamp and fix the filter 203, and the extended portions of the side walls can provide precise limiting within the thickness range of the filter 203 to avoid loosening or slipping of the filter 203 due to thickness differences.

[0107] Continue to refer to Figure 2 andFigure 5 In this embodiment, the elastic limiting structure 130 further includes a second elastic bump 134, and the second elastic bumps 134 are distributed at the straight-edge edges of the first end face 110.

[0108] In this embodiment, by adding the second elastic bumps 134, the horizontal movement of the filter 203 relative to the first end face 110 is further restricted. The second elastic bumps 134 are distributed at the straight-edge edges of the first end face 110 to enhance the fixing effect of the filter 203 and prevent it from undergoing horizontal displacement during installation and use.

[0109] Specifically, in addition to the original first elastic bumps 131, the elastic limiting structure 130 further includes second elastic bumps 134. The second elastic bumps 134 are evenly distributed along the straight-edge edges of the first end face 110, and their function is to provide additional limiting during the installation process of the filter 203 to prevent the filter 203 from moving in the horizontal direction relative to the first end face 110.

[0110] The second elastic bumps 134 and the first elastic bumps 131 act together to form a complete limiting system, enabling the filter 203 to be firmly fixed in the horizontal direction. The first elastic bumps 131 are mainly used to fix the corners of the filter 203, while the second elastic bumps 134 provide further support and limitation at the straight-edge positions, thereby ensuring that the filter 203 will not undergo horizontal sliding under the action of external forces.

[0111] Refer to Figures 1 to 5 , in a preferred embodiment, the first end face 110 is rectangular;

[0112] The elastic limiting structure 130 further includes four first elastic bumps 131, and the four first elastic bumps 131 are respectively provided at the four corners of the first end face 110;

[0113] The number of the second elastic bumps 134 is two, and the two second elastic bumps 134 respectively extend along the straight-edge edges of two opposite sides of the first end face 110.

[0114] This embodiment adopts a rectangular first end face 110 and combines multiple first elastic bumps 131 and second elastic bumps 134 to achieve effective limiting and fixing of the filter 203 and ensure the stability of the filter 203 during assembly and use.

[0115] In this preferred embodiment, the first end face 110 is rectangular, and the elastic limiting structure 130 includes four first elastic bumps 131 and two second elastic bumps 134 to provide comprehensive limiting for the filter 203.

[0116] Four first elastic bumps 131 are respectively arranged at four corners of the first end face 110. The function of the first elastic bumps 131 is to provide limit at the corners of the filter 203 to prevent the filter 203 from moving at the four corner positions. This arrangement ensures the stability of the filter 203 in the corner area, enabling the filter 203 to be firmly held on the rectangular end face.

[0117] Two second elastic bumps 134 are respectively arranged along the edges of two straight sides of the first end face 110 that are opposite sides. The function of the second elastic bumps 134 is to limit the horizontal movement of the filter 203 on the first end face 110 and provide additional support and limit in the direction parallel to the opposite sides of the filter 203. This setting effectively prevents the filter 203 from sliding horizontally, further enhancing its fixing effect.

[0118] By the combined use of the four first elastic bumps 131 and the two second elastic bumps 134, the elastic limit structure 130 can achieve all-round limit and fixation of the filter 203, ensuring that the filter 203 will not be displaced or loosened in all directions after installation.

[0119] In the preferred limit structure design of this embodiment, through the combination of the rectangular shape of the first end face 110 and the elastic limit structure 130, the full fixation of the filter 203 is achieved. The four first elastic bumps 131 ensure the stability of the filter 203 at the corners, while the two second elastic bumps 134 further limit the horizontal movement of the filter 203 in the straight-edge direction. This design effectively prevents the filter 203 from loosening or sliding during assembly and use, improving the overall assembly efficiency and use reliability. At the same time, the elastic limit structure 130 is simple and easy to implement, facilitating manufacturing and installation, capable of reducing production costs and enhancing the stability of the assembly process.

[0120] In some embodiments, the filter seal 10 is a component made of elastic rubber material;

[0121] And / or, the elastic limit structure 130 is integrally formed with the frame 100.

[0122] In this embodiment, the filter seal 10 can be a component made of elastic rubber material. The use of elastic rubber material can provide good elasticity and sealing effect, effectively absorbing external impacts and ensuring the firm installation of the filter 203.

[0123] In addition, the elastic limit structure 130 can be integrally formed with the frame 100. This integral molding method can reduce the number of components, simplify the assembly process, and improve the stability and durability of the overall structure, thereby reducing production costs and enhancing the assembly efficiency.

[0124] The present invention further provides a filter sealing system comprising a filter 203 and a filter seal 10 as described in the aforementioned embodiment. The specific structure of the filter seal 10 is similar to that of the aforementioned embodiment. Since the present filter sealing system utilizes all the technical solutions of all the aforementioned embodiments, it at least exhibits all the technical effects provided by the technical solutions of the aforementioned embodiments, and therefore will not be further detailed here. Specifically, the filter 203 is mounted on the first end surface 110 of the filter seal 10. The second end surface 120 of the filter seal 10 is partially configured with sealing protrusions 121, which are distributed around the light transmission aperture.

[0125] The present filter sealing system inherits the technical solutions of all the above embodiments and has all the corresponding technical effects, including preventing fogging, improving assembly efficiency, extending service life, etc.

[0126] Specifically, see Figure 3 and Figure 4 The filter 203 is installed on the first end surface 110 of the filter seal 10. Its main function is to filter light to achieve the specific wavelength light output required in the skin care device, thereby improving the care effect.

[0127] The first end surface 110 of the filter seal 10 is used to mount the filter 203, ensuring the stable placement of the filter 203. The second end surface 120 of the filter seal 10 is partially provided with sealing protrusions 121. These sealing protrusions 121 are distributed around the light-transmitting hole 111, ensuring that a sealed cavity is formed between the filter 203 and the light-transmitting element 202, thereby further improving the sealing performance of the system and preventing external environmental factors (such as moisture) from affecting the filter.

[0128] In this embodiment, the optical filter 203 is secured to the system via the filter seal 10. The sealed cavity formed between the sealing protrusion 121 and the light-transmitting element 202 effectively prevents the ingress of external air, preventing fogging of the optical filter or light-transmitting element. This sealing design ensures that light can stably pass through the filter and that its intensity and quality are unaffected by the external environment. Furthermore, the elastic material of the filter seal 10 can absorb some impact, thus protecting the optical filter 203.

[0129] The present invention further provides a skin care device 20 comprising a mounting housing 200, a light emitting device 201, a light transmissive member 202, a filter 203, and a filter seal 10 as described in the aforementioned embodiment. The specific structure of the filter seal 10 is similar to that of the aforementioned embodiment. Since the present skin care device 20 utilizes all the technical solutions of all the aforementioned embodiments, it at least has all the technical effects of the technical solutions of the aforementioned embodiments, and therefore will not be described in detail here. The mounting housing 200 has a light outlet 200a.

[0130] The light-transmitting member 202 is installed at the light-emitting port 200a;

[0131] The light-emitting device 201 is installed in the installation housing 200, and the light-emitting device 201 is used to emit light toward the light-transmitting member 202;

[0132] Wherein, the filter 203 is installed between the light-emitting port 200a and the light-emitting device 201 through the filter seal 10. At least a part of the side of the filter 203 facing away from the first end face 110 faces the light-emitting device 201, and the sealing protrusion 121 is configured to form a sealed cavity with at least a part of the light-transmitting member 202.

[0133] Refer to Figures 6 to 9 In this embodiment, a sealed cavity is formed between the sealing protrusion 121 and at least a part of the light-transmitting member 202, which can effectively prevent the occurrence of fogging.

[0134] Specifically, the installation housing 200 has a light-emitting port 200a, and the light-transmitting member 202 is installed at the light-emitting port 200a. The light-emitting device 201 is installed in the installation housing 200 and is used to emit light toward the light-transmitting member 202. The filter 203 is installed between the light-emitting port 200a and the light-emitting device 201 through the filter seal 10. At least a part of the side of the filter 203 facing away from the first end face 110 faces the light-emitting device 201.

[0135] Sealing protrusions 121 are formed on the second end face 120 of the seal. These sealing protrusions 121 are distributed around the light-transmitting holes 111 and are configured to form a sealed cavity with at least a part of the light-transmitting member 202. Through this design, a relatively sealed space is formed between the filter 203 and the light-transmitting member 202, thereby effectively preventing fogging.

[0136] Fogging is usually caused by the condensation of water vapor in the air on the surface of the light-transmitting member 202 when the surface temperature of the light-transmitting member 202 drops. This will cause the light transmittance of the light-transmitting member 202 to decrease, affecting the light output effect of the skin care device 20, and further reducing the treatment or beauty effect. In addition, fogging may also interfere with the uniformity of light, resulting in inconsistent irradiation effects during the use of the device, seriously affecting the user experience and the use effect of the device.

[0137] By providing the sealing protrusions 121 on the second end face 120 of the seal, a sealed cavity is formed between the filter 203 and the light-transmitting member 202, which can effectively prevent external humid air from entering this area, thereby avoiding the condensation of water vapor into fog on the surface of the light-transmitting member 202. This sealing structure design ensures that the surface of the light-transmitting member 202 remains dry, avoiding problems such as a decrease in light transmittance and uneven irradiation effects caused by fogging.

[0138] In this embodiment, by providing a sealing protrusion 121 on the second end face 120 of the filter seal 10 to form a sealed cavity with the light-transmitting member 202, the occurrence of fogging is effectively prevented. In this way, not only is the light transmittance and light uniformity during the use of the device ensured, but also the overall nursing effect and user experience are improved. At the same time, the design of the sealing structure is simple and easy to manufacture, which can enhance the reliability and service life of the device.

[0139] Refer to Figures 9 to 13 , in this embodiment, the skin care device 20 further includes a reflector cup 204 installed in the installation housing 200. The reflector cup 204 has a reflection port 204a for reflecting the light of the light-emitting device 201 to the light outlet 200a, and at least a part of the light-emitting device 201 is located inside the reflector cup 204;

[0140] Wherein, the size F of the reflection port 204a is equal to the inner diameter G of the light-transmitting hole 111 of the filter seal 10; or, the size F of the reflection port 204a is smaller than the inner diameter G of the light-transmitting hole 111 of the filter seal 10.

[0141] In this embodiment, by reasonably setting the size relationship between the reflection port 204a and the light-transmitting hole 111, unnecessary light interference is avoided, ensuring the normal operation and use effect of the device.

[0142] Specifically, the skin care device 20 includes a reflector cup 204 installed in the installation housing 200. The reflector cup 204 has a reflection port 204a for reflecting the light of the light-emitting device 201 to the light outlet 200a, and at least a part of the light-emitting device 201 is located inside the reflector cup 204. There are two cases for the relationship between the size F of the reflection port 204a and the inner diameter G of the light-transmitting hole 111 of the filter seal 10:

[0143] The size F of the reflection port 204a is equal to the inner diameter G of the light-transmitting hole 111 of the filter seal 10, ensuring that the reflected light can completely pass through the light-transmitting hole 111 of the filter 203, but will not irradiate other parts of the filter seal 10. The filter seal 10 is made of an elastic material. If the light directly irradiates it, it may cause the material to be heated and deformed, aged, blackened, and even affect the fixing effect of the filter 203, thereby reducing the service life and performance of the device.

[0144] The size F of the reflection port 204a is smaller than the inner diameter G of the light-transmitting hole 111 of the filter seal 10. In this case, the reflected light can still completely pass through the light-transmitting hole 111 of the filter 203, while ensuring that no extra light irradiates the elastic material part of the filter seal 10. This design further reduces the light scattering and unnecessary energy loss, ensuring that the light is focused on the required area and improving the light utilization efficiency of the device.

[0145] It should be specifically noted that the inner diameter G of the light-transmitting hole 111 of the filter seal 10 refers to the effective area that can actually transmit light. This dimension is directly related to the light transmission efficiency, so it is necessary to match the dimension F of the reflection port 204a to ensure that light can pass through without obstruction.

[0146] In this embodiment, by designing the dimension F of the reflection port 204a of the reflector cup 204 to be equal to or less than the inner diameter G of the light-transmitting hole 111 of the filter seal 10, it is possible to effectively prevent the light of the light-emitting device 201 from directly irradiating the elastic material of the filter seal 10. This reduces the problems of deformation or aging caused by material heating, thereby improving the service life of the filter seal 10 and the stability of the device.

[0147] The above are only partial or preferred embodiments of the present invention. Whether in terms of text or drawings, they cannot limit the scope of protection of the present invention. Any equivalent structural transformation made using the content of the specification and drawings of the present invention under the overall concept of the present invention, or any direct / indirect application in other related technical fields, is included in the scope of protection of the present invention.
