[0003] In the prior art, hair removal devices generate heat during use, especially when components such as light-emitting components and circuit boards are in operation for a long time. In order to maintain the normal operation of the device and the safety of users, these hair removal devices are usually equipped with heat dissipation facilities. Most of these heat dissipation solutions are traditional heat dissipation methods, such as using a fan to blow directly to the circuit board or setting heat dissipation holes to achieve the purpose of heat dissipation.

[0004] However, existing heat dissipation solutions have certain limitations. Most of these solutions do not take into account the annular structure design of the device, resulting in the inability to achieve annular heat dissipation. This deficiency leads to low heat dissipation efficiency, especially around key components of the hair removal device, such as the light-emitting component, which may not be able to obtain sufficient heat dissipation. Due to uneven heat dissipation, the stability and service life of the device will be affected, and it may also cause discomfort to the user during use. Utility Model Content

[0034] The embodiments of the present application will be described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments.

When a component is considered to be "located on" another component, it may be directly located on the other component or there may be a central component at the same time.

[0036] An embodiment of the present application provides a hair removal device, comprising a housing and a circuit board disposed on the housing, and the hair removal device further comprises:

[0037] A fan is arranged on the circuit board;

[0038] A heat dissipation channel is annularly arranged on the housing, and an air inlet of the heat dissipation channel is arranged directly opposite to the fan;

[0039] A light emitting component is arranged in the heat dissipation channel;

[0040] The heat sink surrounds the heat dissipation channel and the light-emitting component in a ring shape.

[0041] The hair removal device provided above can achieve more uniform and efficient air cooling by introducing an annular heat dissipation channel in conjunction with a fan. The fan is set to allow the air flow to flow continuously throughout the annular heat dissipation channel, thereby effectively reducing the temperature of the light-emitting components and circuit boards. In addition, the annular wrapping design of the radiator not only enhances the structural stability of the entire heat dissipation system, but also ensures the comprehensiveness of the heat dissipation effect, and can keep the temperature of the device within a safe range even when used for a long time.

[0042] Some embodiments of the present application are described in detail below in conjunction with the accompanying drawings. In the absence of conflict, the following embodiments and features in the embodiments can be combined with each other.

[0043] See also Figure 1-Figure 5 The embodiment of the present application provides a hair removal device 100, comprising a housing 10, a circuit board 20 disposed on the housing 10, a fan 30, a heat dissipation channel 40, a light emitting component 50 and a heat sink 60. The fan 30 is disposed on the circuit board 20; the heat dissipation channel 40 is annularly disposed on the housing 10, and the air inlet 40a of the heat dissipation channel 40 is disposed directly opposite to the fan 30; the light emitting component 50 is disposed in the heat dissipation channel 40; and the heat sink 60 annularly wraps the heat dissipation channel 40 and the light emitting component 50.

[0044] It should be noted that the hair removal device 100 adopts the design of the annular heat dissipation channel 40 in conjunction with the fan 30 and the radiator 60, which effectively improves the heat dissipation efficiency. Such a design allows the heat generated by the light-emitting component 50 and the circuit board 20 to be dissipated quickly and evenly, ensuring the stability and safety of the hair removal device 100 during long-term use.

[0045] Furthermore, the light emitting component 50 is placed in the heat dissipation channel 40, and can provide necessary lighting during hair removal.

[0046] Furthermore, due to the good heat dissipation effect, the hair removal device 100 is more comfortable to use, reducing the discomfort or safety risks caused by overheating of the device. At the same time, its ring design is not only beautiful, but also makes it easier to hold and operate.

[0047] Furthermore, by combining different types of light-emitting components 50 and adjustable lighting, the hair removal device 100 can provide customized hair removal solutions for different skin problems and user needs.

[0048] In summary, this hair removal device 100, through its innovative heat dissipation and light emitting design, not only improves the safety and comfort during use, but also meets the user's needs for high-efficiency and multi-functional hair removal.

[0049] The hair removal device 100 further includes a hair removal head 70 disposed at one end of the housing 10;

[0050] The heat sink 60 is partially located in the housing 10 and abuts against the heat dissipation channel 40 , and partially extends out of the housing 10 and abuts against the hair removal head 70 .

[0051] It should be noted that the arrangement of the hair removal head 70 enables the hair removal device 100 to focus on hair removal on a specific skin area, such as the face.

[0052] Furthermore, part of the heat sink 60 is located inside the housing 10 and abuts against the heat dissipation channel 40, and the other part extends out of the housing 10 and abuts against the epilator 70. This design can effectively transfer the heat generated by the light-emitting component 50 and the circuit board 20 to the epilator 70, and further dissipate it to the external environment, thereby maintaining a suitable temperature of the device. Such a heat dissipation mechanism is conducive to maintaining the long-term stable operation of the device, and also increases the comfort during use.

[0053] Furthermore, by partially extending the heat sink 60 to the hair removal head 70, the discomfort felt by the user during use due to overheating of the device can be reduced, thereby increasing the safety and comfort during use.

[0054] Furthermore, since the temperature of the epilator head 70 is effectively controlled, highly effective phototherapy and other cosmetic treatments can be more safely applied directly to the skin, thereby improving the epilator effect.

[0055] In summary, this design not only ensures the operational stability and safety of the hair removal device 100, but also improves its effectiveness and efficiency in centralized skin care.

[0056] The heat sink 60 includes a heat dissipation portion 61 and a heat conduction portion 62 disposed on the heat dissipation portion 61;

[0057] The heat dissipation portion 61 is disposed in the housing 10 and abuts against the heat dissipation channel 40 . One end of the heat conduction portion 62 is disposed on the heat dissipation portion 61 , and the other end extends out of the housing 10 and abuts against the epilator head 70 .

[0058] It should be noted that the heat dissipation portion 61 is located in the housing 10 and is close to the heat dissipation channel 40, which helps to effectively absorb and disperse the heat generated by the circuit board 20 and the light-emitting component 50. The provision of the heat conduction portion 62 further enhances the heat dissipation effect and directly dissipates the heat of the heat dissipation portion 61 to the external environment, thereby further increasing the heat dissipation efficiency.

[0059] Furthermore, the above solution effectively dissipates heat, and this design helps maintain a suitable temperature of the internal components of the device, reduces damage or performance degradation that may be caused by overheating, and thus extends the service life of the device.

[0060] Furthermore, since the heat sink 60 effectively transfers heat from the inside of the device to the outside, the temperature of the part touched by the user during use (especially the epilation head 70) is maintained at an appropriate level, which increases the comfort and safety during use.

[0061] In summary, the design of the radiator 60 not only optimizes the heat dissipation efficiency of the hair removal device 100 and maintains the stability and safety of the device, but also provides users with a more comfortable and more effective beauty care experience.

[0062] The heat dissipation channel 40 and the housing 10 are arranged to form an air outlet 40 b , and the heat dissipation portion 61 is disposed opposite to the air outlet 40 b .

[0063] It should be noted that the design of the air outlet 40b allows hot air to be smoothly discharged from the interior of the hair removal device 100. When the heat dissipation portion 61 faces the air outlet 40b, the hot air can be guided to the outside more directly and efficiently, which helps to improve the overall heat dissipation efficiency.

[0064] Furthermore, by aligning the heat dissipation portion 61 with the air outlet 40b, it can be ensured that the heat absorbed by the radiator 60 is effectively discharged, thereby reducing the temperature inside the hair removal device 100. This is essential for maintaining the circuit board 20 and other sensitive components operating within a safe temperature range.

[0065] Furthermore, a stable internal temperature helps protect the device's electronic components from damage or performance degradation due to overheating, thereby improving the reliability and service life of the device.

[0066] Furthermore, through effective heat dissipation design, the discomfort caused by overheating of the device during use can be reduced, thereby improving the comfort of the user experience.

[0067] In summary, through the clever design of the heat dissipation channel 40 and the shell 10 to form the air outlet 40b, and the layout of the heat dissipation part 61 aligned with the air outlet 40b, the hair removal device 100 can not only dissipate heat more effectively, but also improve the overall use experience and beauty effect.

[0068] The hair removal device 100 further includes a refrigeration element 80;

[0069] The cooling element 80 is disposed around the hair removal head 70 and abuts against the heat conducting portion 62 .

[0070] It should be noted that when the cooling element 80 is disposed on the epilating head 70 , the cooling sheet can absorb the heat in the epilating head 70 and dissipate it through the radiator 60 , thereby further improving the heat dissipation efficiency.

[0071] Furthermore, since the refrigeration element 80 is disposed on the epilator head 70 , when the refrigeration sheet is cooled, the temperature of the epilator head 70 can be lowered, thereby realizing the cold compress function of the epilator head 70 and improving the application range of the epilator 100 .

[0072] In a specific embodiment, there are a plurality of refrigeration components 80 , and the plurality of refrigeration components 80 are evenly distributed in an annular manner on the epilation head 70 .

[0073] It should be noted that the uniform distribution of the plurality of cooling elements 80 ensures that a uniform and consistent cold therapy effect is provided over the entire area where the epilator head 70 contacts the skin. This is particularly important for comprehensively and evenly treating skin problems, such as reducing swelling, soothing tired skin, etc.

[0074] Further, the evenly distributed cooling elements 80 can transfer the cooling sensation to the skin more quickly and efficiently, which helps to quickly relieve skin heat, especially after heat therapy or light therapy.

[0075] Furthermore, the evenly distributed cooling elements 80 can provide a more comfortable and pleasant use experience, especially in hot weather or when the skin feels hot.

[0076] Furthermore, even cold therapy helps avoid skin discomfort or damage caused by uneven temperatures. This is especially important for sensitive skin or skin after high temperature treatments, providing a soothing and cooling effect safely.

[0077] Furthermore, since the cooling elements 80 are evenly distributed in an annular shape, the hair removal head 70 can more effectively remove hair from a specific facial area.

[0078] In summary, the design of multiple cooling elements 80 evenly distributed in an annular shape on the epilator head 70 enhances the versatility, safety and comfort of the epilator 100, making it an efficient, comprehensive beauty device suitable for a variety of care needs.

[0079] In a specific embodiment, the cooling element 80 is a semiconductor cooling sheet.

[0080] The heat dissipation channel 40 includes a first section 41, a second section 42 and a third section 43 which are connected to each other;

[0081] The first section 41 and the third section 43 are disposed on opposite sides of the housing 10 , and the first section 41 is disposed opposite to the fan 30 ;

[0082] The air inlet 40a is opened on the first section 41, the second section 42 is arranged opposite to the hair removal head 70, and the third section 43 is connected to the air outlet 40b.

[0083] It should be noted that by dividing the heat dissipation channel 40 into three parts, the air flow path can be more effectively controlled, thereby improving the heat dissipation efficiency. The first section 41 is arranged directly opposite to the fan 30, which helps to guide the cold air into the heat dissipation channel 40; the third section 43 is connected to the air outlet 40b to facilitate the discharge of hot air.

[0084] Furthermore, the second section 42 of the heat dissipation channel 40 is arranged opposite to the hair removal head 70, which means that this part of the heat dissipation channel 40 can provide heat dissipation for the hair removal head 70 in a targeted manner, especially when the light emitting component 50 or other heating elements are used.

[0085] Furthermore, such a heat dissipation channel 40 design helps to maintain the ideal temperature of the internal components of the hair removal device 100 and avoid overheating, thereby protecting the circuit board 20 and other sensitive components and extending the service life of the device.

[0086] Furthermore, effective heat dissipation ensures that the device will not overheat during use, thereby improving comfort and safety during use. Moreover, the division and layout of the heat dissipation channel 40 not only optimizes the use of the internal space of the device, but also increases the attractiveness of the appearance design of the hair removal device 100.

[0087] In summary, the design of the segmented heat dissipation channel 40 not only improves the heat dissipation efficiency and device performance of the hair removal device 100, but also optimizes the user experience and the aesthetics of the device.

[0088] The light emitting component 50 is disposed in the second section 42 , and the heat dissipation portion 61 is supported on an outer wall of the second section 42 .

[0089] It should be noted that placing the heat dissipation portion 61 on the outer wall of the second section 42 where the light emitting assembly 50 is located can effectively absorb and conduct away the heat generated by the light emitting assembly 50. This centralized heat dissipation design helps to improve heat dissipation efficiency, especially when the light emitting assembly 50 generates high heat during use.

[0090] Furthermore, the light emitting assembly 50 is usually sensitive to temperature, and excessively high temperature may damage its performance or shorten its service life. By placing the heat dissipation portion 61 close to the outer wall of the second section 42, the light emitting assembly 50 can be ensured to operate within a preferred temperature range to maintain its stability and efficiency.

[0091] Furthermore, the light emitting component 50 is often used in the hair removal device 100 for phototherapy, such as LED phototherapy, for hair removal. Effective heat dissipation ensures the stability and safety of the device during the phototherapy process, thereby improving the treatment effect.

[0092] Furthermore, by effectively controlling the temperature of the light emitting component 50 area, the risk of discomfort or burns to the user due to overheating of the device during use can be avoided. Moreover, the design of closely combining the light emitting component 50 and the heat dissipation part 61 not only improves the heat dissipation efficiency, but also makes the internal structure of the hair removal device 100 more compact and efficient.

[0093] In summary, the design of arranging the light-emitting component 50 in the second section 42 of the heat dissipation channel 40 and closely attaching the heat dissipation portion 61 on the outer wall not only effectively improves the heat dissipation efficiency, but also protects the key light-emitting component 50, thereby improving the overall performance of the hair removal device 100 and the user experience.

[0094] In a specific embodiment, the light emitting assembly 50 includes a reflective cup 51 and a light emitting member 52;

[0095] The reflective cup 51 is fixed on the inner wall of the second section 42 , the light emitting component 52 is fixed on the housing 10 , and the light emitting component 52 is located between the reflective cup 51 and the hair removal head 70 .

[0096] It should be noted that the design of the reflective cup 51 helps to concentrate and reflect the light emitted by the light-emitting element 52, thereby enhancing the intensity and uniformity of the illumination.

[0097] Furthermore, placing the light emitting element 52 between the reflective cup 51 and the hair removal head 70 can ensure that the light is directly irradiated onto the skin, thereby improving the hair removal effect.

[0098] Furthermore, the design of the reflective cup 51 can not only improve light efficiency, but also reduce light scattering, thereby reducing possible irritation or damage to the user's eyes.

[0099] Furthermore, the design of the built-in light-emitting component 50 not only makes the appearance of the hair removal device 100 more modern and attractive, but also reflects the characteristics of a professional-grade beauty device. The light-emitting component 52 is fixed to the housing 10, located between the reflective cup 51 and the hair removal head 70, which helps to better disperse the heat and reduce the burden of the heat dissipation part 61.

[0100] The hair removal device 100 further includes a filter 90 , which is disposed on the hair removal head 70 and is used to adjust the light emitted by the light emitting element 52 .

[0101] It should be noted that the filter 90 can be used to select or change the specific wavelength of the light passing through, which is particularly important for hair removal on different skin types.

[0102] Furthermore, the filter 90 can filter out light that is harmful to the skin (such as ultraviolet rays), thereby reducing the risk of skin damage.

[0103] Furthermore, by precisely controlling the wavelength and intensity of the light, the filter 90 helps to improve the effectiveness of light therapy and specifically address specific skin problems.

[0104] Furthermore, the use of the filter 90 can reduce the stimulation of light to the user's eyes, making the light therapy process more comfortable. By replacing different types of filters 90, the hair removal device 100 can be applied to a variety of different skin treatments, increasing the versatility of the device. It is suitable for users with various skin types and different skin problems, so that the hair removal device 100 can meet the needs of a wider user group.

[0105] The hair removal device 100 provided above can achieve more uniform and efficient air cooling by introducing the annular heat dissipation channel 40 in combination with the fan 30. The fan 30 is provided so that the air flow continues to flow in the entire annular heat dissipation channel 40, thereby effectively reducing the temperature of the light-emitting component 50 and the circuit board 20. In addition, the annular wrapping design of the radiator 60 not only enhances the structural stability of the entire heat dissipation system, but also ensures the comprehensiveness of the heat dissipation effect, and can keep the temperature of the device within a safe range even when used for a long time.

[0106] The above is only an implementation method of the present application. It should be pointed out that a person skilled in the art can make improvements without departing from the inventive concept of the present application, but these improvements are within the scope of protection of the present application.
