[0030] See also Figure 1 and Figure 2 , Figure 1 This is a schematic diagram of the structure of an air intake structure of an embodiment of the light therapy beauty device of the present utility model. Figure 2 It is a schematic diagram of an exploded view of an air intake structure of an embodiment of the light therapy beauty device of the present invention.

[0031] The present invention provides a beauty instrument, which includes:

[0032] The operating part 100 is held by the user and the working part 200 is in contact with the skin. The working part 200 partially extends into the operating part 100 , and a first air duct 104 is formed between the part of the working part 200 extending into the operating part 100 and the inner wall of the operating part 100 .

[0033] In this embodiment, the structure generally adopted by the operating part 100 is made of high temperature resistant material, and the shape can be designed to be ergonomic so that the user can hold it comfortably. In addition, the operating part 100 also has the function of accommodating various components. The specific internal design of the operating part 100 has enough space to accommodate electronic components, such as circuit boards, batteries, heat dissipation components 301, etc. These components are installed in the internal space of the operating part 100, which can provide mechanical protection and reduce damage caused by collisions.

[0034] The working part 200 in contact with the skin is usually equipped with multiple electrodes, and the structure and layout of these electrodes are carefully designed to ensure that the skin can be beautified evenly. The electrodes are usually made of materials with good conductivity, such as metal or alloy, and may be coated with a biocompatible coating on the surface to reduce irritation to the skin.

[0035] The role of the electrodes is to transfer electrical or thermal energy to the skin for different cosmetic purposes. For example, in hair removal, the electrodes transfer enough heat to the hair follicles to destroy their ability to grow. In skin rejuvenation and anti-aging, the electrodes can help stimulate collagen production, thereby improving the elasticity and appearance of the skin.

[0036] In addition, the design of the working part 200 also takes into account the contact area and shape with the skin to ensure maximum cosmetic effect and comfort. The shape of the working part 200 can be designed according to the skin contours of different areas of the user so that it can fit the skin closely and ensure effective transmission and distribution of energy.

[0037] In general, the design of the working part 200 and the electrodes is crucial to the beauty effect and user experience of the beauty instrument. They not only need to ensure the effective transfer of energy, but also take into account the comfort and safety of the user. By optimizing the design of these components, the performance of the device and the beauty effect can be improved.

[0038] At the same time, the space between the inner wall of the operating part 100 and the extending part of the working part 200 is designed as a first air duct 104. Such a design not only helps to dissipate heat, but also reduces noise during operation of the device.

[0039] During operation, when the device is turned on and begins to perform skin treatment, the light source generates heat. At this time, the first air duct 104 allows external cold air to flow in, pass through the inside of the device, take away the heat, and then be discharged from the air outlet 103 of the device. In this process, since the second opening 301a is located at the connection between the operating part 100 and the working part 200, rather than directly at the operating part 100, the user's hand will not block the second opening 301a, thereby ensuring the efficiency of air circulation.

[0040] In the technical solution of the utility model, by partially extending the working part 200 into the operating part 100, a first air duct 104 is formed between the part of the working part 200 extending into the operating part 100 and the inside of the grip, thereby effectively improving the heat dissipation efficiency. Compared with the traditional design, this embodiment avoids the problem of the user's hand blocking the second opening 301a during use, thereby avoiding overheating or damage to the device caused by insufficient heat dissipation. In addition, when the working part 200 contacts the user's skin, cold air flows through the skin, which not only helps dissipate heat, but also reduces the temperature of the skin, protects the skin from heat damage, and improves the user's experience and the safety of the device.

[0041] Continue reading Figure 1 In this embodiment, the first air duct 104 is disposed around the working portion 200 .

[0042] In this embodiment, the first air duct 104 is arranged around the working part 200 in various forms, which may be a continuous annular channel or a plurality of independent channels distributed around the working part 200. The design of these channels may be determined according to the specific needs of the device and the expected heat dissipation effect. For example, a continuous annular channel may provide a more uniform airflow distribution, while a plurality of independent channels may provide stronger heat dissipation in a specific area.

[0043] During operation, the airflow enters from the second opening 301a at the connection between the operating part 100 and the working part 200, and then flows along the first air duct 104 surrounding the working part 200. Such a flow path helps to take away heat from the heat-generating components such as the electrodes and light sources of the working part 200, and discharge it through the air outlet 103 of the device, thereby effectively reducing the operating temperature of the device.

[0044] The benefit of the surround setting is that it provides a larger heat dissipation area and a more optimized airflow path. This not only improves the heat dissipation efficiency, but also reduces the potential risk to the skin caused by local overheating. In addition, the surround first air duct 104 can also provide customized heat dissipation solutions in different device usage modes, such as hair removal or skin rejuvenation, to meet the thermal management needs of different beauty processes. The flexibility and efficiency of this design make the beauty instrument more reliable and safe, while also improving the user's comfort experience.

[0045] See also Figure 3 , Figure 3 It is a schematic cross-sectional view of the air intake structure of the light therapy beauty device of the present utility model.

[0046] In this embodiment, a avoiding portion 201 b is provided on the outer wall of the working portion 200 for avoiding airflow.

[0047] In this embodiment, the avoidance portion 201b can adopt a variety of structural forms, such as grooves, protrusions or guide plates. These structures can be designed according to the principles of airflow dynamics to optimize the path of the airflow and reduce resistance. Among them, the use of grooves can increase the contact area between the airflow and the surface of the device, thereby improving the heat dissipation efficiency; the protrusions can be used to guide the direction of the airflow to prevent the airflow from directly impacting the skin; the guide plates can evenly distribute the airflow on the outer wall of the working part 200.

[0048] The way the airflow passes through the avoidance portion 201b depends on the specific structure of the avoidance portion 201b. If it is a groove, the airflow will form a vortex in the groove to increase the efficiency of heat exchange; if it is a protrusion, the airflow will flow along the surface of the protrusion to reduce direct impact on the skin; if it is a guide plate, the airflow will be guided to a specific area of ​​the device to achieve more precise heat dissipation control.

[0049] In this embodiment, by optimizing the airflow path, the noise during the operation of the device can be reduced and the user's comfort can be improved. At the same time, the design of the avoidance portion 201b can also protect the user's skin and avoid discomfort or damage caused by excessive airflow. In addition, a reasonable design of the avoidance portion 201b can also help extend the service life of the device because it can reduce damage to electronic components caused by overheating. In general, the setting of the avoidance portion 201b allows the phototherapy beauty device to provide effective beauty while ensuring safety and comfort during use.

[0050] Furthermore, we can Figure 3 As can be seen from the figure, the avoidance portion 201b is arranged around the working portion 200, and the avoidance portion 201b is arc-shaped.

[0051] In this embodiment, the arc-shaped design of the avoidance portion 201b is preferred because the arc-shaped structure can better conform to the principle of airflow dynamics, reduce airflow resistance, and can also be more beautifully integrated into the overall design. The arc-shaped avoidance portion 201b can provide a smoother airflow path, reduce turbulence generated when the airflow passes through, and thus improve heat dissipation efficiency.

[0052] When the airflow passes through the arc-shaped avoidance portion 201b, it flows along the arc-shaped curve. This flow path helps to evenly disperse the airflow, ensuring that the airflow can cover more areas of the working part 200. Such a design not only helps to improve the heat dissipation efficiency, but also reduces the direct impact of the airflow on the skin, thereby improving the comfort of the user.

[0053] In this embodiment, the arc-shaped avoidance portion 201b can optimize airflow management and heat dissipation performance. Since the airflow path is smoother, the noise generated by the device during operation will be reduced accordingly, further improving the user experience.

[0054] Continue reading Figure 2 In this embodiment, the operating part 100 and the working part 200 are assembled and fixed. The operating part 100 includes a second half shell 101 and a first half shell 106. The inner walls of the second half shell 101 and the first half shell 106 are both provided with a first mounting protrusion 101a; the side wall of the working part 200 is provided with a second mounting protrusion 201a that is directly opposite to the first mounting protrusion 101a. The second mounting protrusion 201a cooperates with the first mounting protrusion 101a to relatively fix the second half shell 101, the first half shell 106 and the working part 200.

[0055] In this embodiment, the first mounting protrusion 101a and the second mounting protrusion 201a can be mounted by clamping, threading or other mechanical fixing methods. These methods can ensure the stability between the operating part 100 and the working part 200, and are also convenient for disassembly when maintenance or replacement of parts is required. In this embodiment, the protrusion design is selected because they can form a certain interval between the second half shell 101, the first half shell 106 and the working part 200. This interval is a part of the first air duct 104, which is conducive to air circulation and heat dissipation.

[0056] During the assembly process, the first mounting protrusions 101a on the second half shell 101 and the first half shell 106 can be aligned with the second mounting protrusions 201a on the side wall of the working part 200, and then the second half shell 101, the first half shell 106 and the working part 200 are fixedly connected by snapping or screwing, and there is also a certain gap between the second half shell 101, the first half shell 106 and the working part 200 to form the first air duct 104. The formation of the first air duct 104 ensures that the electronic components inside the device have enough space for heat dissipation, thereby improving the stability and service life of the device. Secondly, due to the spacing of the first air duct 104, the device can more effectively discharge heat during operation to prevent overheating.

[0057] Continue reading Figure 2 In this embodiment, an inclined surface is provided on the outer wall of the second half shell 101 and the first half shell 106 close to the working part 200, and the inclined surface is inclined toward the working part 200. The inclined surface is used to reduce the resistance of the second half shell 101 and the first half shell 106 to the airflow.

[0058] In this embodiment, the inclined surfaces provided on the outer walls of the second half shell 101 and the first half shell 106 close to the working part 200 can be formed in a variety of ways, such as by injection molding, machining or 3D printing, etc. These methods can accurately produce the required inclination angle and shape to meet different design requirements and functional requirements.

[0059] In this embodiment, when the airflow passes through the inclined surface, due to the existence of the inclined surface, the airflow will flow along the inclination direction of the inclined surface, and the inclination direction of the inclined surface is toward the first air duct 104 at the working part 200. This can effectively reduce the resistance generated when the airflow contacts the outer shell, allowing the airflow to enter the first air duct 104 more smoothly. At the same time, the design of the inclined surface reduces the generation of turbulence, thereby reducing the airflow resistance.

[0060] The setting of the inclined surface reduces the resistance to airflow, so that more cold air can quickly pass through the first air duct 104 and take away more heat. In addition, the design of the inclined surface also helps to reduce the noise when the device is running, and improves the user experience.

[0061] See also Figure 3 In this embodiment, the heat dissipation component 301 is further included in the second half shell 101 and the first half shell 106. The second half shell 101 and the first half shell 106 are connected to each other to form a third air duct 102 connected to the outside. The second opening 301a of the heat dissipation component 301 is connected to the first air duct 104, and the exhaust end of the heat dissipation component 301 is connected to the third air duct 102.

[0062] In this embodiment, the type of heat dissipation component 301 may include but is not limited to a fan, a heat sink, a heat pipe or a liquid cooling system. Each of these components has its own advantages. For example, a fan can provide forced air convection, a heat sink can increase the heat dissipation area, a heat pipe can quickly conduct heat, and a liquid cooling system can take away a large amount of heat through liquid circulation.

[0063] During the working process of the heat dissipation component 301 and the first air duct 104, when the device is running and generates heat, the second opening 301a of the heat dissipation component 301 draws in external cold air through the first air duct 104. When the cold air passes through the heat dissipation component 301, it takes away the heat and is then discharged to the outside of the device through the third air duct 102. In this process, the effective operation of the heat dissipation component 301 is closely matched with the design of the first air duct 104, ensuring that the heat can be discharged quickly and effectively.

[0064] The addition of the heat dissipation component 301 can significantly improve the heat dissipation efficiency of the device, ensure that the device operates stably at a safe temperature, and extend the service life. Secondly, efficient heat dissipation also helps protect the user's skin and avoid discomfort or injury caused by overheating of the device, thereby ensuring the safety of the use process while providing effective beauty.

[0065] In some embodiments, a light emitting element is further included. The light emitting element is disposed inside the heat dissipation component 301 and is disposed close to the second opening 301 a of the heat dissipation component 301 .

[0066] In this embodiment, the type of light-emitting element may include LED lamps, laser devices or optical fibers, etc., which are widely used in beauty devices due to their high efficiency and long life. LED lamps have a variety of wavelength options and can be customized according to different skin beauty needs; laser devices can provide more precise beauty; and optical fibers can direct light to the skin area that needs beauty.

[0067] The role of arranging the light-emitting element near the second opening 301a of the heat dissipation assembly 301 is twofold. First, such a layout helps to immediately absorb the heat generated by the light-emitting element when it is working, reducing the impact on the life of the light-emitting element itself. Second, because the cold air first passes near the light-emitting element, this can reduce the risk of thermal damage to the skin during the light beauty process to a certain extent.

[0068] In this embodiment, the light-emitting element is arranged near the second opening 301a of the heat dissipation assembly 301, which helps to improve the overall heat dissipation efficiency. When the cold air passes through the light-emitting element, it not only takes away the heat generated by the light-emitting element, but also provides pre-cooled air for the heat dissipation assembly 301, so that the heat dissipation assembly 301 can work more efficiently. This design optimizes the heat dissipation system of the device, ensures that the device can maintain stable performance after working for a long time, and also improves the user experience and safety.

[0069] See also Figure 4 , Figure 4 The structure diagram of the third air duct 102 is shown.

[0070] In this embodiment, at least the second half shell 101 is provided with an air outlet 103 , and one end of the third air duct 102 is in communication with the air outlet 103 .

[0071] In this embodiment, there are at least two ways to form the air outlet 103, wherein the air outlet 103 may be disposed on the second half shell 101 or the first half shell 106, and this formation method may be integrally formed during injection molding or stamping of the second half shell 101 or the first half shell 106. Of course, in addition to this, a notch may be provided on the corresponding parts of the second half shell 101 and the first half shell 106, and the air outlet 103 may be formed when the second half shell 101 and the first half shell 106 are joined.

[0072] In this embodiment, when the heat dissipation component 301 is working, the inhaled cold air will become hot after taking away the heat generated inside. The hot air then flows through the third air duct 102 and is finally discharged from the outside of the device through the air outlet 103. In this process, the design of the third air duct 102 ensures that the airflow is correctly guided and flows smoothly, avoiding excessive turbulence of the airflow inside the device, thereby improving the heat dissipation efficiency. In this way, the connection design between the air outlet 103 and the third air duct 102 allows the hot air to be discharged directly from the inside of the device, reducing the accumulation of heat inside the device. At the same time, the smooth airflow reduces the airflow resistance and turbulence, thereby reducing the noise when the device is running.

[0073] See also Figures 3 to 5 , Figure 3 This is a cross-sectional diagram of the air intake structure of the light therapy beauty device of the utility model. Figure 4 shows a structural diagram of the third air duct 102, Figure 5 It is a schematic diagram of the structural decomposition of the third air duct 102.

[0074] In this embodiment, two first guide ribs 102a are spaced apart on the inner wall of the second half shell 101 , and two second guide ribs 102b are disposed on the inner wall of the first half shell 106 . The two first guide ribs 102a face the two second guide ribs 102b to form a third air duct 102 .

[0075] In this embodiment, the two first guide ribs 102a and the two second guide ribs 102b cooperate to form the third air duct 102, wherein, in addition to the two first guide ribs 102a and the two second guide ribs 102b facing each other, the third air duct 102 can also be formed in a staggered arrangement. Such a design can increase the air tightness of the third air duct 102. In addition, in this embodiment, the guide channel formed by the two first guide ribs 102a and the two second guide ribs 102b has a certain curvature, and such a curved channel helps to smooth the airflow and reduce the airflow resistance.

[0076] In this embodiment, the airflow, under the guidance of the third air duct 102 formed by the two first guide ribs 102a and the two second guide ribs 102b, will flow along a set arc path. This guiding method allows the airflow to reach the air outlet 103 more smoothly, thereby improving the heat dissipation efficiency. At the same time, the arc design also helps to reduce the noise generated by the airflow during the flow process.

[0077] Continue reading Figure 3 In this embodiment, a middle frame 302 is further included. The middle frame 302 is arranged between the second half shell 101 and the first half shell 106 . A third vent 302 a is arranged on the middle frame 302 . The third vent 302 a is directly opposite to the air outlet 103 .

[0078] In this embodiment, the configuration structure of the third vent 302a can be expanded into various forms to improve the efficiency of airflow. For example, the third vent 302a can be designed to have an aerodynamically optimized shape, such as an elliptical or streamlined shape, which can reduce airflow resistance and increase airflow speed. In addition, the edge of the third vent 302a can be processed into a chamfer or a smooth transition to reduce turbulence at the airflow outlet.

[0079] In this embodiment, when the airflow passes through the third vent 302a, the hot air moves along the third air duct 102 under the action of the heat dissipation component 301. When it reaches the middle frame 302, due to the alignment of the third vent 302a with the air outlet 103, the airflow can flow out directly from the third vent 302a without generating too much resistance or turbulence at the middle frame 302. This allows the airflow to be discharged from the inside of the device more smoothly, effectively reducing the internal temperature. In this way, the design of the third vent 302a can ensure efficient heat dissipation of the beauty instrument, which not only improves the performance of the device, but also helps to protect the internal electronic components and extend the life of the device.
