[0002] A portable beauty instrument is an instrument that uses light of a specific wavelength to irradiate the skin to achieve a beauty effect.

[0038] like Figure 1 and Figure 2 As shown, Figure 1 The figure shows the installation structure diagram of the heat dissipation assembly of the utility model. Figure 2 It is a structural schematic diagram of an embodiment of the heat dissipation component of the utility model.

[0039] The beauty instrument of this embodiment includes:

[0040] The heat dissipation assembly includes a first docking shell 100 and a second docking shell 200. The first docking shell 100 and the second docking shell 200 are buckled together to form a first cavity 300 and a second cavity 400. The second cavity 400 is located on one side of the first cavity 300. The first cavity 300 is configured with a second opening 301, and the second cavity 400 is configured with a third opening 401. The first cavity 300 is connected to the second cavity 400 to form a second air duct.

[0041] In this embodiment, the heat dissipation device is mainly used to dissipate heat and cool the beauty instrument during operation. There are many types of beauty instruments, and these devices may include but are not limited to the following:

[0042] 1. Photorejuvenation device is a device that uses specific wavelengths of light to improve skin conditions, such as reducing wrinkles, spots and acne.

[0043] 2. Laser hair remover uses laser to destroy hair follicles, thereby achieving long-term hair removal effects.

[0044] 3. Radio frequency skin tightening device, which uses radio frequency energy to heat the deep layer of the skin and stimulate collagen reorganization to achieve the purpose of tightening the skin.

[0045] 4. LED phototherapy devices that use specific colors of LED light to treat inflammation, promote wound healing or fight skin aging.

[0046] 5. Use ultrasonic technology to enhance the skin's ability to absorb skin care products, while also helping to tighten the skin.

[0047] These devices will generate a certain amount of heat during use, so an effective heat dissipation system is required to protect the electronic components of the device and ensure the safety of the user. The heat dissipation component design of this embodiment can form a second air duct structure, which is very critical for these devices and can improve the heat dissipation efficiency, thereby maintaining the stable operation of the device and extending its service life.

[0048] In this embodiment, the cooperation principle between the first docking shell 100 and the second docking shell 200 is based on the consideration of improving air tightness and heat exchange efficiency. The first docking shell 100 and the second docking shell 200 are connected together by a precise buckle design. This design utilizes the principle of mechanical interlocking, in which the edges of the shells can have complementary protrusions and grooves so that the two can be tightly buckled together, so that there is almost no gap between the two shells, which greatly improves the air tightness of the entire heat dissipation assembly. The improvement of air tightness means that the flow of gas in the channel will not be disturbed by the external environment, thereby ensuring the uniformity of air flow and the effective transfer of heat. When the first docking shell 100 and the second docking shell 200 are buckled, they jointly define an internal space, namely the second air duct. This channel allows hot air to flow upward from the first cavity 300 to the second cavity 400 and be discharged through the vent of the second cavity 400.

[0049] Due to the improvement of the air tightness and flow uniformity of the second air duct, the hot air is more fully in contact with the inner wall of the housing and the light-emitting member 5 when passing through the channel, which increases the heat exchange area and thus improves the heat dissipation efficiency. In addition, compared with the traditional multi-piece heat dissipation assembly, the two-piece design in this embodiment simplifies the structure, reduces the complexity of manufacturing and assembly, and also reduces the cost.

[0050] Through this design, the heat dissipation component of this embodiment not only improves the heat dissipation efficiency, but also improves the reliability and maintainability of the entire beauty instrument by reducing the number of components and simplifying the structure.

[0051] In the technical solution of this embodiment, the first docking shell 100 and the second docking shell 200 are buckled together to form the first cavity 300 and the second cavity 400 located on one side of the first cavity 300, and the first cavity 300 and the second cavity 400 are connected to form a second air duct. Compared with the existing heat dissipation assembly formed by splicing multiple shells, the heat dissipation assembly of the utility model only uses the first docking shell 100 and the second docking shell 200 to buckle together to form the first cavity 300 and the second cavity 400 located on one side of the first cavity 300, and the first cavity 300 and the second cavity 400 are connected to form the second air duct. In this way, the two shells form the second air duct, avoiding the existence of a large number of splicing gaps, improving the air tightness of the second air duct, making the gas flow more uniform and the heat exchange area increased, thereby improving heat dissipation and cooling.

[0052] Continue reading Figure 2 In this embodiment, the second cavity 400 and the first cavity 300 are staggered; and / or, the second cavity 400 is located above the first cavity 300.

[0053] In this embodiment, the second cavity 400 and the first cavity 300 are staggered, so that the second air duct formed by the second cavity 400 and the first cavity 300 can be lengthened, which is conducive to the heat source being set in the second cavity 400 or the first cavity 300, so that the heat dissipation airflow can fully pass through the heat source to take away the heat of the heat source. Alternatively, the second cavity 400 is located above the first cavity 300. Such a design means that there will be a height difference between the second opening 301 and the third opening 401. This embodiment uses this to enhance natural convection. Specifically, the setting positions of the first air inlet and the second air inlet can be designed as a height difference setting. Such a design can achieve heat dissipation and cooling through the natural flow of airflow; taking the skin rejuvenation device as an example, the device adopts the light-emitting component 5 to be set in the first cavity 300. When the beauty instrument is started and the light-emitting component 5 in the first cavity 300 starts to work, the light-emitting component 5 emits light for skin beauty and also starts to generate heat. Due to the operation of the light emitting element 5 , the temperature of the air in the first cavity 300 gradually increases, resulting in a decrease in the density of the hot air and a relatively high density of the cold air.

[0054] According to the natural convection principle that hot air rises and cold air sinks, the hot air in the first cavity 300 naturally rises into the second cavity 400 and is discharged through the third opening 401. At the same time, the second opening 301 of the first cavity 300 allows cold air to enter and replace the heated air. In this way, the hot air in the first cavity 300 is continuously taken away, and the inflow of cold air helps to reduce the temperature.

[0055] In this process, the structural design of the first cavity 300 and the second cavity 400 becomes the key, because they need to ensure the unobstructed flow of the second air duct, allowing for effective exchange of hot air and cold air. In addition, the material selection and thickness of the first docking shell 100 and the second docking shell 200 also need to be considered to ensure sufficient thermal conductivity so that heat can be transferred from the light-emitting element 5 to the housing and dissipated to the environment through natural convection. Through this design without the need for additional heat dissipation equipment, the beauty instrument can achieve effective heat dissipation and cooling while maintaining a simple structure. Such a design not only reduces the complexity and cost of the device, but also improves the reliability and convenience of maintenance of the device.

[0056] Further, see Figure 3 , Figure 3 It is a cross-sectional view of an embodiment of the heat dissipation component of the present utility model.

[0057] In this embodiment, the heat dissipation assembly further includes a heat dissipation fan 302 , and the heat dissipation fan 302 is disposed in the second cavity 400 .

[0058] In this embodiment, the design of the heat dissipation fan 302 is mainly to enhance the flow speed of the airflow on the basis of the above-mentioned embodiment, thereby achieving a better heat dissipation effect. There are many ways to install the heat dissipation fan 302. For example, the heat dissipation fan 302 can be directly installed inside the second cavity 400. This method can make the fan closer to the heat source and reduce the airflow leakage caused by the connection between the heat dissipation fan 302 and the second air duct, thereby improving the heat dissipation efficiency. The built-in installation also helps to protect the fan from the influence of the external environment and extend its service life.

[0059] Of course, in some embodiments, the heat dissipation fan 302 can also be installed outside the second cavity 400, which can reduce the occupation of the internal space and is particularly suitable for designs with limited space. External installation can also facilitate the maintenance and replacement of the fan. If it is to better combine with the characteristics of natural convection, the heat dissipation fan 302 can be installed on the top of the second cavity 400, and the natural law of hot air rising can be used to help promote the discharge of hot air.

[0060] Regardless of the above installation method, the main function of the heat dissipation fan 302 is to increase the flow speed of the airflow, and to improve the efficiency of the entire heat dissipation system by accelerating the discharge of hot air and the introduction of cold air. Such a design not only improves the heat dissipation effect, but also increases the adaptability of the device and the user's operational flexibility.

[0061] See also Figure 3 and Figure 4 , Figure 3 This is a cross-sectional view of an embodiment of the heat dissipation component of the utility model. Figure 4 for Figure 3 A magnified schematic diagram of center A.

[0062] In this embodiment, a light outlet 403 is provided on a side of the first cavity 300 facing away from the second cavity 400 , and a light emitting element 5 is also provided in the first cavity 300 , which is opposite to the light outlet 403 and is used to emit light for irradiating skin care.

[0063] In this embodiment, the light emitting element 5 is mainly used to emit light for beautifying the skin. There are many types of light emitting elements 5, such as LED (light emitting diode). The LED light emitting element 5 emits light through semiconductor materials and can generate light of multiple different wavelengths. It is suitable for various skin treatments, such as red light treatment for inflammation and blue light treatment for acne.

[0064] Of course, it can also be a laser light emitting element 5, wherein the laser light emitting element 5 emits high-intensity light of a single wavelength, which is commonly used for laser hair removal and pigmentation treatment. Alternatively, a halogen lamp or IPL light emitting element 5 can be used to emit wide-band light to provide customized treatment for different skin problems, such as skin rejuvenation, spot removal, etc.

[0065] Taking the halogen lamp lighting element 5 as an example, its working process is as follows:

[0066] When the device is turned on, the halogen light emitting element 5 starts to emit light. After passing through the filter, these lights form light of a specific wavelength that penetrates the surface layer of the skin and reaches the deep layer of the skin, stimulating cells to produce photobiological effects, promoting the production of collagen and repairing tissues. Light of different wavelengths corresponds to different therapeutic effects. For example, red light can promote blood circulation, blue light can kill bacteria that cause acne, and near-infrared light can promote collagen regeneration.

[0067] Continue reading Figure 3 In this embodiment, a connecting port 3040 is formed at the connecting point between the first cavity 300 and the second cavity 400. The connecting port 3040 is formed at one end of the first cavity 300, and the second opening 301 is provided at the other end of the first cavity 300. The airflow driven by the heat dissipation fan 302 passes through the connecting port 3040 and the second opening 301 respectively to dissipate heat for the light-emitting component 5.

[0068] In this embodiment, the reason why the connecting port 3040 is arranged at one end of the first cavity 300 is that such a design can better dissipate heat for the light-emitting component 5. Specifically, the light-emitting component 5 can be in a strip shape and installed in the first cavity 300. During operation, the heat dissipation fan 302 drives the airflow to enter from the second opening 301, and contacts with the surface of one end of the light-emitting component 5 for heat exchange. As the heat dissipation fan 302 continues to drive the airflow to the other end of the light-emitting component 5, at this time, the connecting port 3040 is also arranged at this end, that is, one end of the first cavity 300, corresponding to the other end of the light-emitting component 5; such a setting allows the airflow to flow from one end of the light-emitting component 5 to the other end, that is, the airflow will pass through the entire surface of the light-emitting component 5, so that not only the dead corners of heat accumulation are effectively avoided, but also the heat exchange area is increased.

[0069] Continue reading Figure 3 , 4 and Figure 8 , Figure 3 This is a cross-sectional view of an embodiment of the heat dissipation component of the utility model. Figure 4 for Figure 3 The enlarged schematic diagram of point A in the middle. Figure 8 It is a schematic diagram of the installation of the heat dissipation component and the mounting plate 304.

[0070] In this embodiment, the beauty instrument further includes a mounting plate 304, the mounting plate 304 at least partially extends into the first cavity 300, and the light emitting member 5 is disposed at the portion of the mounting plate 304 extending into the first cavity 300; or

[0071] A mounting component 501 is mounted on one end of the mounting plate 304 . The mounting component 501 extends into the first cavity 300 and is used for mounting the light-emitting element 5 .

[0072] In this embodiment, the mounting plate 304 can be a main control circuit board, which mainly provides installation and electrical connection for other devices. In addition, a part of it can be directly extended into the first cavity 300 for installing the light-emitting component 5; the design flexibility of the mounting plate 304 allows it to adapt to the structural requirements of the beauty instrument in different ways. Part of the mounting plate 304 can be directly extended into the first cavity 300, and the light-emitting component 5 can be installed with this part. The advantage of doing so is that the transmission distance between the light-emitting component 5 and the circuit on the mounting plate 304 can be reduced, and the resistance can be reduced. In addition, this part of the mounting plate 304 can be used as part of the heat dissipation path, which helps to directly transfer the heat generated by the light-emitting component 5 to the heat dissipation component.

[0073] Another design is to set a special mounting member 501 at one end of the mounting plate 304, which is specially used to mount the light-emitting element 5 and extends it into the first cavity 300. This design makes it easier to install and replace the light-emitting element 5, and also provides a more stable supporting structure for the light-emitting element 5.

[0074] The above two different installation methods provide design flexibility and can be adjusted according to different equipment models and user needs.

[0075] Specifically, the specially provided mounting member 501 includes a first bracket 501a and a second bracket 501b. Figure 8 As shown, the first bracket 501a extends from the second opening 301 into the first cavity 300;

[0076] The first docking shell 100 has a mounting portion on one side facing the second docking shell 200 , and the second docking shell 200 has a mounting mating portion 201 on one side facing the first docking shell 100 . The mounting mating portion 201 is used to allow the second bracket 501 b to extend into the first cavity 300 , and to cooperate with the mounting portion to fix the second bracket 501 b .

[0077] In this embodiment, the specific structure of the mounting portion and the mounting matching portion 201 can be a combination of a groove and a protrusion, and specifically the mounting portion can be a protrusion and the mounting matching portion 201 can be a groove. Of course, in other implementations, the two can be interchanged, and no special limitation is made here.

[0078] The first mounting frame and the second mounting frame are mainly used for stable installation of the light source. In terms of installation stability, the first mounting frame and the second mounting frame can adopt high-strength and high-temperature carbon fiber. Carbon fiber has the characteristics of high strength and low weight, and excellent high-temperature resistance. It can ensure that when the light-emitting component 5 works for a long time and generates high temperature, the bracket structure will not be deformed or damaged.

[0079] During the assembly process, first align the first bracket 501a with the second opening 301 and extend it into the first cavity 300, and then extend the second bracket 501b into the first cavity 300 through the installation matching portion 201. After both installation brackets are extended into the first cavity 300, the first docking shell 100 and the second docking shell 200 can be fastened. After fastening, the installation portion and the installation matching portion 201 cooperate to fix the first bracket 501a and the second bracket 501b. The position of the light-emitting component 5 installed on the bracket is locked, and the light-emitting component 5 can remain stable even when the device moves or shakes violently.

[0080] This arrangement not only improves assembly efficiency, but also ensures the stability and safety of the device during operation. The stability of the light-emitting element 5 is crucial to ensuring the cosmetic effect and device life, so the use of this specially designed bracket and buckle mechanism can significantly improve the reliability and durability of the device.

[0081] See also Figure 7 and Figure 8 , Figure 7 This is an exploded view of the heat dissipation component. Figure 8 It is a schematic diagram of the installation of the heat dissipation component and the mounting plate 304.

[0082] In this embodiment, the first docking shell 100 is provided with a first through hole 201a, and the second bracket 501b is provided with a second through hole 501c corresponding to the first through hole 201a for bolts to enter, so that the second bracket 501b and the first docking shell 100 are relatively fixed.

[0083] In this embodiment, by adding corresponding first through holes 201a and second through holes 501c on the first docking shell 100 and the second bracket 501b, the mounting stability of the bracket can be further improved. This design allows bolts to pass through these through holes to firmly connect the second bracket 501b to the first docking shell 100. When the bolts are tightened, they can effectively resist vibration and displacement caused by device operation or external impact, ensuring that the light-emitting element 5 remains in the correct position.

[0084] In this embodiment, the bolts provide a reliable mechanical locking method to ensure that the brackets will not loosen even in the case of severe shaking, so that the two brackets always remain stable. Stable brackets can reduce the risk of damage to the light-emitting element 5 due to vibration. In general, by adding corresponding first through holes 201a and second through holes 501c on the first docking shell 100 and the second bracket 501b and fixing them with bolts, not only the overall stability of the device is improved, but also the long-term reliable operation of the device is guaranteed.

[0085] Continue reading Figure 8In this embodiment, the first bracket 501 a and the second bracket 501 b are spaced apart from each other. Both the first bracket 501 a and the second bracket 501 b are provided with a mounting seat 502 , and the mounting seat 502 is used to mount the light-emitting element 5 .

[0086] In this embodiment, the first bracket 501a and the second bracket 501b are arranged at intervals, wherein each bracket is equipped with a mounting seat 502. It should be noted that the mounting position of the mounting seat 502 is on the same side of the first bracket 501a and the second bracket 501b, which can be Figure 8 It can be seen that the first bracket 501a, the second bracket 501b, and the mounting plate 304 are integrally formed, and a gap is formed between the first bracket 501a and the second bracket 501b, and the gap is used to avoid the light-emitting component 5. With such a design, the light-emitting component 5 can be installed and fixed in a limited space.

[0087] In this embodiment, the design of the first bracket 501a and the second bracket 501b takes into account the influence of the heat generated by the light-emitting element 5 during operation on other parts of the device. By arranging the brackets at intervals and installing the mounting seat 502 on the same side, this mounting structure not only provides a stable mounting platform for the light-emitting element 5, but also effectively isolates the heat through the gap design, reducing the heat conduction to the mounting plate 304 and the bracket.

[0088] In addition, the electrical connection design between the mounting base 502 and the bracket means that the light-emitting element 5 can obtain the required power directly from the bracket. Such direct electrical connection helps to reduce the use of wires, thereby simplifying internal wiring, reducing failure points, and improving the overall reliability and durability of the equipment.

[0090] In this embodiment, the heat dissipation assembly also includes a heat dissipation fin 406 located between the first bracket 501a and the second bracket 501b; a fin mounting portion 404 is relatively provided on the inner wall of the first cavity 300, and the fin mounting portion 404 is used to install the heat dissipation fin 406, and the airflow driven by the heat dissipation fan 302 is also used to dissipate heat from the heat dissipation fin 406.

[0091] In this embodiment, the heat dissipation fins 406 are used to enhance the heat dissipation and cooling capability of the light emitting element 5. To obtain the best effect, the installation position of the heat dissipation fins 406 is also a key factor. In this embodiment, the design and installation position of the heat dissipation fins 406 are carefully considered to ensure maximum heat dissipation efficiency. The heat dissipation fins 406 are installed between the first bracket 501a and the second bracket 501b and are located above the light emitting element 5. This layout utilizes the principle of thermal convection, that is, the natural tendency of hot air to rise, thereby helping to effectively transfer the heat generated by the light emitting element 5 to the heat dissipation fins 406, and thereby dissipate it to the surrounding environment.

[0092] The light-emitting element 5 generates heat when working, and the heat causes the temperature of the surrounding air to rise. The hot air rises due to its low density, and the heat is transferred to the fins when passing through the heat sink fins 406. The heat sink fins 406 transfer heat from the base to each part of the fins through heat conduction. Since the fins have a large surface area, the heat can be quickly dissipated into the air. As the temperature of the heat sink fins 406 increases, they will also dissipate heat to the outside world through thermal radiation. Then, combined with the heat dissipation fan 302 and the vents with a height difference design, the heat generated by the light-emitting element 5 can be quickly discharged, thereby improving the heat dissipation speed and efficiency. At the same time, the fins provide additional heat dissipation surface area, which helps to dissipate heat faster.

[0093] As for the installation method of the heat sink fin 406, continue to refer to Figure 6 The first docking shell 100 and the second docking shell 200 can be installed and fixed by setting a fin mounting portion 404 on the inner wall thereof, wherein the fin mounting portion 404 includes a first protrusion 404a and a second protrusion 404b for clamping the two sides of the heat dissipation fin 406, the first protrusion 404a is set on the side wall of the first docking shell 100, and the second protrusion 404b is set on the side wall of the second docking shell 200.

[0094] In this embodiment, the design of the first protrusion 404a and the second protrusion 404b provides a stable clamping point for the heat sink fin 406, ensuring that the fin can remain stable even when vibration occurs during the operation of the device. This clamping installation method also simplifies the assembly process of the heat sink fin 406, making installation and replacement faster and more convenient.

[0095] And because the fins are directly mounted on the shell, the need for additional fixings is reduced, thereby reducing material costs and equipment weight.

[0096] Through this design, the heat dissipation component of this embodiment can provide an efficient heat dissipation solution while maintaining a compact structure, thereby ensuring that the beauty instrument can maintain good performance and stability under high-load working conditions.

[0097] Continue reading Figures 4 to 6 In this embodiment, the inner wall of the first docking shell 100 is provided with a first guide rib 405a protruding toward the heat dissipation fins 406, and the inner wall of the second docking shell 200 is provided with a second guide rib 405b protruding toward the heat dissipation fins 406. After the first docking shell 100 and the second docking shell 200 are spliced, the first guide rib 405a and the second guide rib 405b are arranged opposite to each other.

[0098] In this embodiment, the airflow is guided by carefully designed guide ribs. When the airflow enters the first cavity 300 through the second opening 301, the first guide rib 405a and the second guide rib 405b begin to play a role. Their presence ensures that the airflow is effectively guided to the heat sink fins 406 and the light-emitting component 5, thereby fully exchanging heat with the surfaces of the heat sink fins 406 and the light-emitting component 5. This design layout enables the airflow to evenly cover every part of the heat sink fins 406, rather than just blowing from above, thereby improving the heat dissipation efficiency. In this way, the cold air is forced to contact the heat sink fins 406 and the light-emitting component 5, achieving comprehensive heat dissipation, ensuring that the temperature of the equipment is controlled within an ideal range, and avoiding any possible heat accumulation.

[0099] In addition, this design also allows the airflow to generate more turbulence when passing through the heat dissipation fins 406, increasing the contact time and contact area between the airflow and the fin surface, thereby improving the heat exchange efficiency and heat dissipation performance, which helps to ensure that the beauty instrument can maintain optimal performance under various working conditions.

[0100] Continue reading Figure 4 In this embodiment, the second opening 301 is constructed on a side of the first cavity 300 facing away from the light outlet 403 and is spaced apart from the second cavity 400; the first guide rib 405a and the second guide rib 405b are constructed on a side wall of the first cavity 300 facing the heat dissipation fin 406 and are spaced apart from the second opening 301;

[0101] The heat dissipation fins 406 are located between the first guide ribs 405 a , the second guide ribs 405 b and the light outlet 403 .

[0102] In this embodiment, the position of the second opening 301 and the layout of the first guide rib 405a and the second guide rib 405b further optimize the design of the heat dissipation system. The second opening 301 is located on the side of the first cavity 300 facing away from the light outlet 403 and is kept at a certain distance from the second cavity 400. Such a setting helps to guide the cold air to flow directly to the side of the heat dissipation fin facing away from the light outlet 403, thereby improving the cooling efficiency.

[0103] The first guide rib 405a and the second guide rib 405b are located on a side wall of the first cavity 300 facing the heat sink fin 406 and are spaced apart from the second opening 301. This design allows the incoming airflow to be effectively guided and dispersed onto the heat sink fin 406, increasing the contact area between the airflow and the fins, thereby improving the heat exchange efficiency.

[0104] The position of the heat sink 406 is also carefully designed, and is located between the first guide rib 405a, the second guide rib 405b and the light outlet 403. This layout not only utilizes the principle of natural convection, but also ensures that the hot air above the light emitting element 5 can directly contact the heat sink fin 406, accelerating the heat dissipation. In this way, it is ensured that the cold air can directly reach the light emitting element 5 and the back of the heat sink fin 406, and the hot air can be effectively discharged through the heat sink fin 406, optimizing the airflow path.
