[0002] Currently, skin care devices that use light energy for skin care typically have a light outlet on the treatment surface of the housing. Inside the housing, a light-transmitting element extends to the light outlet, allowing light emitted from the light source to pass through the element and illuminate the skin. To ensure the light-transmitting element fits snugly into the outlet, a certain distance must be left between them. This gap can easily allow other substances to seep in. Since these devices require direct contact with the skin, they are generally only suitable for use in relatively dry environments, limiting their applicability and resulting in a poor user experience.

Therefore, when the skin care device is used to care for wet skin, liquid on the skin is less likely to enter the housing through the gap between the light outlet and the light-transmitting element, effectively reducing the occurrence of malfunctions due to internal liquid ingress, ensuring the service life and safety of the skin care device. Simultaneously, the skin care device can be used normally in humid environments, expanding its applicable scenarios.

Detailed Implementation

[0026] 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 the embodiments. Based on the embodiments of this application, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this application.

[0027] It should be noted that all directional indicators (such as up, down, left, right, front, back, etc.) in the embodiments of this application are only used to explain the relative positional relationship and movement of each component in a certain specific posture (as shown in the figure). If the specific posture changes, the directional indicator will also change accordingly.

[0028] It should also be noted that when a component is described as "fixed to" or "set on" another component, it can be directly on the other component or there may be an intervening component present. When a component is described as "connected to" another component, it can be directly connected to the other component or there may be an intervening component present.

[0029] Furthermore, the use of terms such as "first" and "second" in this application is for descriptive purposes only and should not be construed as indicating or implying their relative importance or implicitly specifying the number of technical features indicated. Therefore, a feature defined as "first" or "second" may explicitly or implicitly include at least one of that feature. Additionally, the technical solutions of the various embodiments can be combined with each other, but only on the basis of being achievable by those skilled in the art. When the combination of technical solutions is contradictory or impossible to implement, such a combination of technical solutions should be considered non-existent and not within the scope of protection claimed in this application.

[0030] Currently, skin care devices require the installation of light-transmitting components, and a certain size needs to be reserved between the light outlet and the light-transmitting components. Furthermore, the treatment surface needs to be in contact with the skin for use. Therefore, to ensure the safe and stable care provided by the skin care device, existing skin care devices are usually only suitable for use in relatively dry environments, resulting in a limited range of applicable scenarios and a poor user experience.

[0031] The inventors of this application discovered through research on existing skin care devices that the key reason for their limited applicability is the size reserved between the light outlet and the light-transmitting component (i.e., the gap between the light outlet and the light-transmitting component). If the skin care device is used in a humid environment, moisture or liquid may enter the housing through this gap, thereby causing internal component malfunction or damage.

[0032] To this end, the inventors of this application have attempted to improve the skin care device from several aspects, enabling it to be used normally in humid environments. For example, they changed the assembly method of the light-transmitting element and the light-emitting port to avoid gaps between them; they also improved the dimensional accuracy of the light-emitting port and the light-transmitting element to reduce the gap between them; and so on. Ultimately, the inventors of this application have developed a low-cost, simple-to-implement, and effective skin care device that allows for normal use in humid environments.

[0033] In the present application, the skin care device can be a hair removal device with light-based hair removal function, or a beauty device with other skin care functions, such as a photon skin rejuvenation device with skin rejuvenation function.

[0034] Reference Figures 1 to 5 In this embodiment, the skin care device includes a housing 10, a light-transmitting element 20, a light source assembly 30, and a first sealing element 40. The housing 10 has a mounting cavity 11 (i.e., a cavity inside the housing 10) and a care surface 12 for contacting the skin. The care surface 12 has a light outlet 13 communicating with the mounting cavity 11. The light-transmitting element 20 is disposed in the mounting cavity 11, and the light source assembly 30 is disposed in the mounting cavity 11 corresponding to the light-transmitting element 20. The first end of the light-transmitting element 20 extends to be inserted into the light outlet 13. Therefore, when the skin care device is activated and contacted with the skin to be cared for via the care surface 12, the light emitted by the light source assembly 30 can pass through the light-transmitting element 20 and be emitted from the light outlet 13 to irradiate the skin and care for the irradiated area.

[0035] The first sealing element 40 is disposed inside the housing 10, and the first sealing element 40 seals the outer peripheral wall of the light-transmitting element 20 and the housing 10 to seal the gap between the inner peripheral wall of the light outlet 13 and the outer peripheral wall of the light-transmitting element 20. Through the sealing connection of the outer peripheral wall of the light-transmitting element 20 and the housing 10, the first sealing element 40 effectively blocks the channel (i.e., the gap between the inner peripheral wall of the light outlet 13 and the outer peripheral wall of the light-transmitting element 20) that may allow liquid or water vapor to enter the mounting cavity 11 from the nursing surface, preventing liquid or water vapor from entering the mounting cavity 11 from the gap between the light-transmitting element 20 and the light outlet 13.

[0036] The technical solution of the skin care device in this embodiment involves adding a first sealing member 40 inside the housing 10, which seals the outer peripheral wall of the housing 10 and the light-transmitting member 20. This seals the gap between the inner peripheral wall of the light outlet 13 and the outer peripheral wall of the light-transmitting member 20, effectively blocking the passage for liquid on the skin in contact with the care surface 12 to enter the mounting cavity 11. Therefore, when the skin care device cares for wet skin, liquid on the skin is less likely to enter the housing 10 through the gap between the light outlet 13 and the light-transmitting member 20, effectively reducing the possibility of malfunctions due to internal liquid ingress and ensuring the lifespan and safety of the skin care device.

[0037] Furthermore, since the first seal effectively blocks the channels through which liquid or moisture may enter the mounting cavity 11 from the care surface, the skin care device will not malfunction or be damaged when used in a humid environment because liquid or moisture will not enter the housing 10 through the gap between the light outlet 13 and the light-transmitting element 20. This allows the skin care device to be used normally in humid environments, expanding its applicable scenarios. Specific scenarios for using the skin care device in humid environments include: 1. Users can use the skin care device immediately after showering, even if their skin is not completely dry; 2. Users can use the device in bathrooms or spaces with high humidity; 3. Users can use the skin care device immediately after applying moisturizers, serums, gels, or other skin care products, without waiting for the products to be absorbed; 4. Users can use the skin care device directly after exercising or working out, even if they are sweating a lot; etc.

[0038] Thus, the skin care device of this embodiment can be used normally not only in relatively dry environments but also in humid environments, meeting the user's wet-use needs. This allows users to use the skin care device in more scenarios, making it more convenient and improving the user experience. Specifically, for example, after showering and immediately after applying body lotion or moisturizing skincare products (while the skin is damp), users can immediately use the skin care device of this application for care (such as hair removal or skincare) without waiting for the skin to dry. This effectively shortens the user's daily personal care time, saving time and improving the user experience.

[0039] Furthermore, when users apply the skin care device to skin already coated with skincare products (such as body lotion or moisturizing serum), the light irradiation from the device not only enhances the device's own treatment effects but also promotes the absorption of the skincare products, resulting in better efficacy. This achieves simultaneous skincare using the device and skincare products (e.g., hair removal and skin rejuvenation at the same time, or light therapy and skin rejuvenation at the same time), creating a synergistic effect greater than the sum of its parts. Moreover, when used with skincare products or other liquids, the device reduces friction with the skin, increasing the gliding speed and making it suitable for use over large areas.

[0040] In addition, in the technical solution of the skin care device in this embodiment, the first sealing member 40 is disposed inside the housing 10 and will not come into contact with the skin during use. Therefore, during use, the sliding resistance between the care surface 12 and the skin will not be increased, which facilitates the sliding use of the skin care device on the skin.

[0041] In some embodiments, the light-transmitting element 20 may be a light-transmitting crystal, such as a crystal made of sapphire, quartz glass, or optical-grade plastic. When the light-transmitting element 20 is a light-transmitting crystal, it may be a columnar crystal corresponding to the shape of the light-emitting port 13; for example, when the light-emitting port 13 is square, circular, or elliptical, the light-transmitting element 20 corresponds to a square prism, a cylinder, or an elliptical cylinder, respectively.

[0042] Of course, in other embodiments, the light-transmitting element 20 can also be other forms of light-transmitting structure.

[0043] In some embodiments, the first sealing member 40 is further disposed near the first end of the light-transmitting member 20, and the first sealing member 40 is sealed to the outer peripheral wall of the first end of the light-transmitting member 20. In this way, the sealing position of the first sealing member 40 on the gap (that is, the gap between the inner peripheral wall of the light-transmitting port 13 and the outer peripheral wall of the light-transmitting member 20) is closer to the care surface 12, and the distance between the sealing position and the care surface 12 is shorter. That is, the length of the gap between the sealing position and the care surface 12 is shorter, so that the skin care device will not have the problem of a large amount of liquid accumulating in the gap, and cleaning is more convenient.

[0044] In some embodiments, the first sealing member 40 includes a first sealing ring 41 surrounding the light-transmitting member 20. Essentially, the first sealing ring 41 is fitted onto the light-transmitting member 20, sealing the gap between the inner wall of the housing 10 and the outer peripheral wall of the light-transmitting member 20. In this embodiment, the first sealing member 40 uses a simple solution of a first sealing ring 41 surrounding the light-transmitting member 20, effectively sealing the gap between the inner peripheral wall of the light-transmitting port 13 and the outer peripheral wall of the light-transmitting member 20. This approach is low-cost and easy to install.

[0045] In some embodiments, the first sealing ring 41 seals against the outer peripheral wall of the light-transmitting element 20, that is, the sealing connection between the first sealing ring 41 and the outer peripheral wall of the light-transmitting element 20 is abutment.

[0046] In some embodiments, the first sealing ring 41 seals against the inner wall of the housing 10, that is, the sealing connection between the first sealing ring 41 and the inner wall of the housing 10 is abutment.

[0047] In some embodiments, the first sealing ring 41 is sealed and bonded to the outer peripheral wall of the light-transmitting element 20 by waterproof adhesive, that is, the sealing connection between the first sealing ring 41 and the outer peripheral wall of the light-transmitting element 20 is achieved by bonding with waterproof adhesive.

[0048] In some embodiments, the first sealing ring 41 is sealed and bonded to the inner wall of the housing 10 by waterproof adhesive, that is, the sealing connection between the first sealing ring 41 and the inner wall of the housing 10 is achieved by bonding with waterproof adhesive.

[0049] Of course, in addition to the methods listed above, the first sealing ring 41 can also be integrally formed with the housing 10 or integrally formed with the light-transmitting element 20, etc., to seal the inner wall of the housing 10 and the outer peripheral wall of the light-transmitting element 20.

[0050] Reference Figures 1 to 3 In some embodiments, the first sealing ring 41 has an annular boss 42 on the side facing the nursing surface 12, and the inner wall of the housing 10 has an annular groove 14 on the side facing away from the nursing surface 12, which mates with the annular boss 42. The annular boss 42 is interference-fitted into the annular groove 14, and the side of the first sealing ring 41 facing the nursing surface 12 is sealed to the housing 10. The sealing connection between the side of the first sealing ring 41 facing the nursing surface 12 and the housing 10 can be achieved through abutment or adhesion.

[0051] In this embodiment, the annular boss 42 added to the first sealing ring 41 and the corresponding annular groove 14 provided in the housing 10 are interference-fitted, so that the sealing connection between the first sealing ring 41 and the housing 10 includes not only the sealing of the housing 10 and the side of the first sealing ring 41 facing the nursing surface 12, but also the sealing of the annular groove 14 and the annular boss 42. That is, a multi-layer sealing connection is formed between the first sealing ring 41 and the housing 10. Even in extreme cases, if liquid breaks through one of the seals, liquid will not enter the mounting cavity 11 inside the housing 10 from between the seal and the inner wall of the housing 10. Therefore, the stability and reliability of the sealing connection between the first sealing ring 41 and the inner wall of the housing 10 are greatly improved.

[0052] In addition, the interference fit between the annular groove 14 and the annular boss 42 prevents the first sealing ring 41 from deforming and moving away from the light-transmitting element 20, thus better maintaining the stability of the sealing connection between the first sealing ring 41 and the light-transmitting element 20.

[0053] The annular boss 42 can be located at the outer ring edge of the first sealing ring 41, or at the inner ring edge of the first sealing ring 41, or both the outer and inner ring edges of the first sealing ring 41 can be provided with annular boss 42. Of course, the annular boss 42 can also be located at any position between the inner and outer ring edges of the first sealing ring 41, for example, at the center of the first sealing ring 41.

[0054] like Figure 2 As shown, the annular boss 42 is located at the outer ring edge of the first sealing ring 41 and is interference-fitted into the annular groove 14. Figure 1In this design, the seal between the first sealing ring 41 and the housing 10 includes: the seal between the side of the first sealing ring 41 facing the nursing surface 12 and the housing 10, and the seal between the annular boss 42 and the annular groove 14. If liquid is to break through the seal between the first sealing ring 41 and the housing 10 and enter the mounting cavity 11, it needs to first break through the seal between the side of the first sealing ring 41 facing the nursing surface 12 and the housing 10, and then break through the seal between the annular boss 42 and the annular groove 14. Therefore, the sealing strength between the first sealing ring 41 and the housing 10 is greatly improved, and the seal is more reliable.

[0055] In some embodiments, the first sealing ring 41 is sealed against the outer peripheral wall of the light-transmitting element 20 by means of its inner ring edge, thereby achieving a sealed connection between the first sealing ring 41 and the outer peripheral wall of the light-transmitting element 20. Of course, the first sealing ring 41 can also be sealed to the outer peripheral wall of the light-transmitting element 20 in other ways, for example, the inner ring edge of the first sealing ring 41 is bonded to the outer peripheral wall of the light-transmitting element 20.

[0056] like Figure 3 As shown, in some embodiments, the annular boss 42 is located at the inner ring edge of the first sealing ring 41. The side of the annular boss 42 facing the light-transmitting element 20 is sealed and fitted with the light-transmitting element 20. That is, in this embodiment, the side of the annular groove 14 near the light-transmitting element 20 is open. The annular boss 42 is interference-fitted between the outer wall of the light-transmitting element 20 and the groove wall of the annular groove 14, so that the side of the annular boss 42 facing the light-transmitting element 20 is close to the outer peripheral wall of the light-transmitting element 20, and the side of the annular boss 42 facing away from the light-transmitting element 20 is close to the groove wall of the annular groove 14. In this way, the interference fit between the annular boss 42 and the annular groove 14 not only enhances the sealing strength between the first sealing ring 41 and the housing 10, but also enhances the sealing strength between the first sealing ring 41 and the outer wall of the light-transmitting element 20.

[0057] The sealing connection between the first sealing ring 41 and the outer peripheral wall of the light-transmitting element 20 can be achieved by simply having the annular boss 42 facing the light-transmitting element 20 in a sealing fit with the light-transmitting element 20, or by also including the inner ring edge of the first sealing ring 41 sealingly abutting or adhering to the outer peripheral wall of the light-transmitting element 20. This application's... Figure 3 In this process, the sealing connection between the first sealing ring 41 and the outer peripheral wall of the light-transmitting element 20 includes both the sealing fit between the side of the annular boss 42 facing the light-transmitting element 20 and the light-transmitting element 20, and the sealing abutment or adhesion between the inner ring edge of the first sealing ring 41 and the outer peripheral wall of the light-transmitting element 20. In this way, the contact area between the first sealing ring 41 and the outer peripheral wall of the light-transmitting element 20 is larger and the sealing strength is higher.

[0058] In some embodiments, the side of the annular boss 42 facing away from the light-transmitting element 20 is an inclined or curved surface, and the thickness of the annular boss 42 gradually decreases from its bottom to its top. Correspondingly, the groove wall of the annular groove 14 facing the light-transmitting element 20 is an inclined or curved surface adapted to the inclined or curved surface of the annular boss 42, and the width of the annular groove 14 gradually decreases from the groove opening to the groove bottom. Thus, when the annular boss 42 is interference-fitted between the annular groove 14 and the light-transmitting element 20, the squeezing force exerted by the inclined or curved surface of the annular groove 14 on the inclined or curved surface of the annular boss 42 will form a component force in the direction of the light-transmitting element 20, causing the first sealing ring 41 and its annular boss 42 to press more tightly against or adhere to the outer peripheral wall of the light-transmitting element 20, thus better ensuring the sealing strength between the first sealing ring 41 and the outer peripheral wall of the light-transmitting element 20. Furthermore, the annular groove 14 has an open design on one side, which makes it easier to install the first sealing ring 41.

[0059] Of course, in some other embodiments, the side of the annular boss 42 facing away from the light-transmitting element 20 may also be a plane that is approximately parallel to the outer peripheral wall of the light-transmitting element 20; or, the side of the annular boss 42 facing away from the light-transmitting element 20 may be an inclined surface or a curved surface, and the thickness of the annular boss 42 may gradually increase from its bottom to its top; or, the side of the annular boss 42 facing away from the light-transmitting element 20 may be a surface of other shapes.

[0060] refer to Figure 2 and Figure 3 In some embodiments, the skin care device further includes a touch sensor 50 for detecting whether the care surface 12 is in contact with the skin. The touch sensor 50 is disposed in the mounting cavity 11 and located on the side of the first seal 40 opposite to the care surface 12. The first seal 40 is clamped between the touch sensor 50 and the inner wall of the housing 10.

[0061] Because the touch sensor 50 needs to be positioned close to the care surface 12 to ensure detection sensitivity and accuracy, and also needs to be waterproof to prevent liquid from flowing into the touch sensor 50 and causing short circuits, malfunctions, or other abnormalities, this embodiment addresses this by placing the touch sensor 50 against the side of the first seal 40 facing away from the care surface 12. The first seal 40's waterproofing function prevents liquid from flowing into the touch sensor 50, while maintaining a close proximity to the care surface 12 to ensure its detection sensitivity and accuracy. Furthermore, the touch sensor 50 engages with the inner wall of the housing 10 to clamp the first seal 40, ensuring a tight seal between the first seal 40 and the inner wall of the housing 10, thus guaranteeing the sealing strength between them.

[0062] In some embodiments, the skin care device further includes a color sensing component for detecting skin color, the color sensing component including a light guide for acquiring skin color information. The color sensing component operates by acquiring light reflection information of the skin area contacted by the care surface 12 through the light guide, and determining skin color information based on the light reflection information. Since the light guide needs to acquire light reflection information of the contacted skin area, the care surface 12 is provided with a collection port, and one end of the light guide is located at the collection port. To prevent liquid on the skin from entering the housing 10 through the gap between the light guide and the collection port, this embodiment employs a sealing mechanism between the light guide and the collection port, for example, by using a sealing element (such as a sealing ring, waterproof adhesive, etc.) or other sealing methods.

[0063] In this embodiment, while adding a skin color detection function to the skin care device, the waterproof performance of the housing 10 is still maintained, allowing the skin care device to continue to care for damp skin normally.

[0064] like Figure 4 As shown, in some embodiments, the housing 10 is provided with a mounting groove 15, and a touch sensor 50 for detecting whether the care surface 12 is in contact with the skin is installed in the mounting groove 15. The first sealing member 40 seals and covers the opening of the mounting groove 15. In this embodiment, a mounting groove 15 is provided on the housing 10 to install the touch sensor 50 in the mounting groove 15, and the opening of the mounting groove 15 is sealed and covered by the first sealing member 40. In this way, even if liquid enters the interior of the housing 10, the touch sensor 50 in the mounting groove 15 will not be wetted by liquid because the opening of the mounting groove 15 is sealed and covered, thus effectively ensuring the safe and stable operation of the touch sensor 50.

[0065] In this embodiment, the first sealing element 40 can be any of the solutions in the above embodiment or the following embodiments.

[0066] Furthermore, in some embodiments, the opening of the mounting groove 15 is positioned away from the care surface 12, that is, the mounting groove 15 is positioned between the first seal 40 and the care surface 12, and the distance between the mounting groove 15 and the care surface 12 is closer. Thus, the touch sensor 50 positioned in the mounting groove 15 is closer to the care surface 12, resulting in better detection sensitivity and accuracy.

[0067] Of course, in other embodiments, the mounting groove 15 may also be arranged with the groove opening facing other directions; for example, the mounting groove 15 is arranged on the inner peripheral wall of the light outlet 13, with the groove opening of the mounting groove 15 facing the light-transmitting element 20, or tilted towards the second end of the light-transmitting element 20, etc.

[0068] In some embodiments, the mounting groove 15 is arranged around the light outlet 13, that is, the mounting groove 15 is an annular groove surrounding the light outlet 13. In this way, the touch sensor 50 can be arranged around the light outlet 13 along the mounting groove 15 to realize the skin contact detection of various positions of the care surface 12, or the touch sensor 50 can be arranged at the corresponding position of the light outlet 13 according to the detection design requirements to realize the skin contact detection of the corresponding position of the care surface 12.

[0069] Reference Figures 1 to 5 In some embodiments, the skin care device further includes a bracket 60 disposed within the mounting cavity 11. The bracket 60 may be a detachable structure fitted and fixed to the inner wall of the housing 10, or it may be a structure constructed on the inner wall of the housing 10. The bracket 60 has a light guide channel 61 that mates with the light outlet 13, and a light-transmitting element 20 is installed in the light guide channel 61. When the skin care device is in operation, the light-emitting component 30 generates light that enters the light guide channel 61, passes through the light-transmitting element 20 in the light guide channel 61, and then exits from the light outlet 13 to act on the skin that is in contact with the care surface 12.

[0070] The first sealing element 40 is clamped between the bracket 60 and the inner wall of the housing 10. The clamping action of the bracket 60 and the housing 10 on the first sealing element 40 keeps the position of the first sealing element 40 stable, ensuring the sealing strength between the first sealing element 40 and the inner wall of the housing 10. Furthermore, this method of installing and fixing the first sealing element 40 makes the assembly of the first sealing element 40 more convenient and facilitates production and installation.

[0071] Of course, in other embodiments, the first seal 40 can also be assembled and fixed in other ways, or further fixed in combination with other methods based on the above-mentioned fixing methods. For example, by adhesive bonding, by interference fit of concave and convex structures, etc.

[0072] Combined with reference Figures 5 to 7 In some embodiments, the light source assembly 30 includes a lamp tube 31 disposed at the second end of the light-transmitting element 20, and a filter element 32 disposed between the second end of the light-transmitting element 20 and the lamp tube 31. A vacuum cavity V is formed between the filter element 32 and the second end of the light-transmitting element 20 by a second sealing member 70. Thus, since there is no air between the filter element 32 and the light-transmitting element 20, the formation of condensation droplets between the light-transmitting element 20 and the filter element 32 is effectively avoided, thus preventing the light energy from being affected. The filter element 32 can be a filter sheet or filter film disposed facing the second end face of the light-transmitting element 20, and the second sealing member 70 can be a sealing ring surrounding the filter element 32 to seal the edge of the filter element 32 to the edge of the second end face of the light-transmitting element 20, thereby forming a stable vacuum cavity V between the filter element 32 and the second end of the light-transmitting element 20.

[0073] In some embodiments, a covering section 80 is provided between the first sealing member 40 and the second sealing member 70, covering the outer peripheral wall of the light-transmitting member 20. The first sealing member 40, the covering section 80, and the second sealing member 70 are integrally formed. In this embodiment, the covering section 80 covers and adheres to the outer peripheral wall of the light-transmitting member 20, and the first sealing member 40, the covering section 80, and the second sealing member 70 are designed as a single unit. Thus, even if liquid breaks through the seal between the first sealing member 40 and the outer peripheral wall of the light-transmitting member 20, the adhesion between the covering section 80 and the outer peripheral wall of the light-transmitting member 20 will prevent the liquid from continuing to flow into the mounting cavity 11, forming a second layer of sealing protection. Similarly, the sealing connection between the second sealing member 70 and the second end of the light-transmitting member 20 forms a third layer of sealing protection. Therefore, the seal between the first sealing member 40 and the outer peripheral wall of the light-transmitting member 20 is more stable and reliable.

[0074] In some embodiments, the skin care device further includes a cooling element (not shown in the figure, for example, a semiconductor cooling chip) disposed within the mounting cavity 11. A clearance window is provided on the covering section 80, and the cooling element is disposed within the clearance window and abuts against the outer wall of the light-transmitting element 20. In this embodiment, by providing a clearance window on the covering section 80, the cooling element can directly abut against the outer wall of the light-transmitting element 20 through the clearance window. This ensures that the arrangement of the covering section 80 does not affect the cooling effect of the cooling element on the light-transmitting element 20, guaranteeing the cooling effect of the light-transmitting element 20 on the skin and reducing the pain sensation caused by the light energy emitted from the light outlet 13 to the skin.

[0075] In some embodiments, the sidewall of the light-transmitting element 20 is provided with a fixing groove 21, the bracket 60 is provided with a fixing boss 62 corresponding to the fixing groove 21, and the covering section 80 is provided with a clearance hole 82 to avoid the fixing boss 62. The fixing boss 62 passes through the corresponding clearance hole 82 and is engaged in the corresponding fixing groove 21. The bracket 60 is engaged in the fixing groove 21 of the light-transmitting element 20 by the fixing boss 62, thus completing the assembly and fixation of the bracket 60 and the light-transmitting element 20. Furthermore, the fixing boss 62 passing through the clearance hole 82 on the covering section 80 also limits the position of the covering section 80, making the connection between the covering section 80 and the light-transmitting element 20 more stable.

[0076] In some embodiments, the skin care device is a hair removal device that performs normal hair removal by applying light when the care surface 12 is in contact with damp skin. Because the hair removal device has a first sealing element 40 that seals the gap between the outer peripheral wall of the light-transmitting element 20 and the housing 10, liquid is prevented from entering the housing 10 through the gap between the light outlet 13 and the light-transmitting element 20. Therefore, the hair removal device can perform normal hair removal even on wet skin, eliminating the need for users to dry their skin before use, making it more convenient for them.

[0077] Specific scenarios for using hair removal devices in humid environments include: 1. Immediately after showering, even if the skin is not completely dry, users can use the device for hair removal; 2. Using the device in the bathroom or in spaces with high humidity; 3. Immediately after applying moisturizers, serums, gels, or other skincare products, without waiting for them to be absorbed; 4. Immediately after exercising or working out, even if the user is sweating a lot, users can use the device for skincare; etc.

[0078] Therefore, the hair removal device of this embodiment can be used normally not only in relatively dry environments but also in humid environments, meeting the user's wet-use needs. This allows users to perform hair removal in more scenarios, making it more convenient and improving the user experience. Specifically, for example, after showering and immediately after applying body lotion or moisturizing skincare products (when the skin is damp), users can immediately use the hair removal device for care (such as hair removal or skincare) without waiting for the skin to dry. This effectively shortens the user's daily skincare time, saving time and significantly improving the user experience.

[0079] When a user applies a hair removal device to skin that has been coated with skincare products (such as body lotion or moisturizing serum), the light emitted by the device not only removes hair but also promotes the absorption of the skincare products, enhancing their effectiveness. This achieves simultaneous hair removal and skincare benefits, creating a synergistic effect greater than the sum of its parts. Furthermore, when used in conjunction with skincare products or other liquids (such as aloe vera gel), the device reduces friction with the skin, increasing the gliding speed and making it suitable for large-area hair removal.

[0080] In some embodiments, the first sealing ring 41 may be made of silicone, rubber, or other polymer materials with good sealing performance; the second sealing element 70 may be a sealing ring with good heat resistance or other sealing structures.

[0081] This application further proposes a hair removal kit, which includes the aforementioned skin care device and a skin care solution for use with the hair removal device. The skin care device is used to perform hair removal on skin coated with the skin care solution in a moist state. The specific structure of the skin care device is as described in the above embodiments. Since this hair removal kit adopts all the technical solutions of all embodiments of the aforementioned skin care device, it possesses at least all the beneficial effects brought about by the technical solutions of the aforementioned embodiments, which will not be elaborated upon here.
