[0002] Near-infrared light therapy is a medical device that uses near-infrared light for treatment. Near-infrared light is an electromagnetic wave with a wavelength range of 700 nanometers to 1400 nanometers, which is between visible light and infrared light. Near-infrared light has the characteristics of strong penetration, high energy, and good safety, so it has been widely used in the medical field. The working principle of near-infrared light therapy is to irradiate human tissue with near-infrared light to promote blood circulation, accelerate metabolism, relieve pain, promote wound healing, etc. Near-infrared light can penetrate the surface of the skin, reach deep tissues, stimulate cells, and thus produce a therapeutic effect.

[0018] In order to make the purpose, technical solution and advantages of the present application more clearly understood, the present application is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the embodiments described herein are only used to explain the present invention and are not used to limit the present invention.

[0019] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected", and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection, a direct connection, or an indirect connection through an intermediate medium, and it can be the internal connection of two elements or the interaction relationship between two elements. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0020] In the present invention, it is also necessary to explain that the directional terms such as one side, one end, the other end, top and bottom in the embodiments of the present application are only relative concepts or are based on the normal use status of the product, and should not be considered as restrictive.

[0021] like Figure 1 and Figure 3As shown, the embodiment of the present application provides a near-infrared light therapy device, including a main body 1, a light-emitting part 2, a reflecting part 3, a focusing part 4 and a heat dissipation part 5. A cavity 20 is arranged in the main body 1, the light-emitting part 2 is arranged in the cavity 20, the reflecting part 3 is arranged on the light-emitting part 2, the focusing part 4 is arranged on one side of the reflecting part 3, and the heat dissipation part 5 is arranged on one side of the light-emitting part 2; when the light-emitting part 2 starts to work, the heat dissipation part 5 is used to dissipate the heat of the light-emitting part 2, the reflecting part 3 and the focusing part 4, the reflecting part 3 is used to reflect the near-infrared light generated by the light-emitting part 2 to the focusing part 4, and the focusing part 4 is used to receive the near-infrared light of the light-emitting part 2 and the reflecting part 3 and focus it, so that the near-infrared light reaches a preset irradiation intensity. In this embodiment, the main body 1 is the outer shell of the therapy device, which provides protection and support. The cavity 20 is the space inside the main body 1, which is used to accommodate and fix other components. This design ensures the stability and durability of the equipment, and also facilitates maintenance and replacement of components. The light-emitting part 2 is the core component of the physiotherapeutic instrument, which is responsible for generating near-infrared light. Near-infrared light has the characteristics of strong penetration and good thermal effect, and can be used to promote blood circulation, relieve pain, accelerate wound healing, etc. The setting of the light-emitting part 2 enables the physiotherapeutic instrument to provide a continuous and stable near-infrared light source. The function of the reflector 3 is to reflect the near-infrared light generated by the light-emitting part 2 to the focusing part 4. Through the precise design of the reflector 3, it can be ensured that the near-infrared light propagates along a predetermined path, thereby improving the utilization rate of light and the therapeutic effect. For example, the reflector 3 can use a mirror or a special coating material to improve the reflection efficiency and reduce light loss. The focusing part 4 is used to receive the near-infrared light from the light-emitting part 2 and the reflecting part 3 and focus it. By focusing, the near-infrared light can reach a preset irradiation intensity, thereby improving the therapeutic effect. The design of the focusing part 4 needs to consider the propagation path and focusing effect of the light to ensure that the light can accurately irradiate the treatment area. The function of the heat dissipation part 5 is to dissipate heat from the light-emitting part 2, the reflecting part 3 and the focusing part 4. Since the light-emitting unit 2 generates heat during operation, if the heat dissipation is poor, it may cause the device to overheat, affecting its performance and life. The design of the heat dissipation unit 5 needs to consider factors such as heat dissipation efficiency, heat dissipation area and heat dissipation method to ensure that the device can maintain a stable temperature when working for a long time.

[0022] Specifically, through the near-infrared light generated by the light-emitting part 2, the physical therapy device can penetrate into the skin tissue, promote blood circulation, relieve pain, accelerate wound healing, etc. The design of the reflecting part 3 and the focusing part 4 ensures that the near-infrared light can propagate along a predetermined path and reach a preset irradiation intensity, thereby improving the therapeutic effect. The design of the main body 1 and the cavity 20 makes the physical therapy device have a compact structure, which is easy to carry and store. Users can easily take the device to different places as needed, which is convenient for family and personal use. The design of the heat dissipation part 5 ensures that the device can maintain a stable temperature when working for a long time, thereby extending the service life of the device. The stable performance enables the physical therapy device to continuously provide efficient therapeutic effects and meet the needs of users. This design solves the problem of overheating of the light-emitting part 2 through a reasonable structure and heat dissipation system, and can provide sufficient light intensity without sacrificing portability, avoiding the limitation that low power cannot produce therapeutic effects.

[0023] like Figure 3As shown, further, the light focusing part 4 includes a light guide cavity 40, a first light focusing member 41 and a second light focusing member 42, the light guide cavity 40 is arranged on one side of the reflecting part 3, the first light focusing member 41 and the second light focusing member 42 are respectively arranged on the light guide cavity 40, and the first light focusing member 41 is arranged on the side of the light guide cavity 40 close to the light emitting part 2. In this embodiment, the light guide cavity 40 is a structure for transmitting light. Its function is to guide the light generated from the light emitting part 2 and effectively transmit it to the first light focusing member 41 and the second light focusing member 42. The light guide cavity 40 usually has a reflective surface or a special geometric shape, so that the light can be reflected or refracted inside it, thereby avoiding the loss of light. Through the design of the light guide cavity 40, the light can be transmitted along a predetermined path by reflection or refraction, which can reduce the loss of light and ensure that the light can be effectively concentrated on the subsequent light focusing part 4. For example, in the design of the light source, the light guide cavity 40 can help convert the uneven light source distribution into a uniform light output. The first light concentrator 41 is arranged on the light guide cavity 40, close to one side of the light emitting part 2. The function of the first light concentrator 41 is to collect the light transmitted from the light guide cavity 40 and concentrate or focus it. Generally, such a light concentrator can be a lens, a reflector or an optical element of other shapes, which converges the light to a small area by changing the path of the light. The function of the first light concentrator 41 is to perform preliminary focusing and light collection on the light, thereby improving the intensity and directionality of the light, and making the light more concentrated or concentrated in the target area. For example, in an optical projection device, the first light concentrator 41 can help adjust the light beam of the light source so that it is evenly distributed during the projection process. The second light concentrator 42 is arranged on the light guide cavity 40, located on the other side of the first light concentrator 41. The second light concentrator 42 usually further focuses or expands the light from the first light concentrator 41. Its purpose is to further adjust the shape, intensity or direction of the light beam to ensure that the quality and characteristics of the final output light meet the predetermined requirements. The function of the second light concentrator 42 is to finely adjust the shape of the light beam to ensure that the light has a suitable angle and light intensity when it is finally output. It can further accurately control the light beam to avoid excessive scattering of light or deviation from the predetermined path. For example, in the lighting system, the design of the second light concentrator 42 can ensure that the range and light intensity of light irradiation are uniform, thereby improving the lighting effect. Combining the light guide cavity 40, the first light concentrator 41 and the second light concentrator 42 can achieve precise control of the light source. In principle, the light guide cavity 40 is responsible for the initial guidance of light, the first light concentrator 41 is responsible for focusing, and the second light concentrator 42 further optimizes the shape and intensity of the light beam. The infrared light of the near-infrared light therapy device is finally output through the second light concentrator 42. This hierarchical design helps to reduce the scattering and loss of light, thereby improving the efficiency of the overall optical system. Through reasonable design and configuration, higher quality light output can be obtained, improving the performance of the system.

[0024] like Figure 2As shown, further, the first light concentrator 41 includes a first curved surface end and a first plane end, the second light concentrator 42 includes a second curved surface end and a second plane end, the first plane end is fitted with the second plane end, the first curved surface end is arranged on the side of the light guide cavity 40 close to the light emitting part 2, and the second curved surface end is arranged on the side of the light guide cavity 40 away from the light emitting part 2. In this embodiment, the first curved surface end is usually used to collect and focus the light. The curved arc surface can guide or reflect the light from the light emitting part 2 to the focal point. Specifically, the shape of the curved surface end can help focus the light into a specific direction or a smaller area, reducing the scattering of the light. The plane end usually helps to fit with the second plane end, so that the two light concentrators can be joined in an orderly manner and ensure that the light transmission effect is not disturbed. The position and shape of the plane end can be used to ensure the close fit and accurate alignment between the light concentrator and other components (such as the light guide cavity 40). This design can ensure that when the light is transmitted from the light guide cavity 40, it will be properly concentrated and guided when it contacts the first curved surface end of the first light concentrator 41. The design of the plane end helps to stabilize the position of the optical component and avoid light deviation and distortion. For example, in a projector, the first light concentrator 41 may guide the light from the light source (such as LED or laser) to the first focal point, thereby ensuring that the projection light is concentrated and avoiding scattering, so that the projection effect is clearer. The second curved end of the second light concentrator 42 is to further focus or expand the light. The shape of this curved end may be different from the first curved end, and is used to fine-tune or precisely adjust the light that has been focused by the first light concentrator 41. Through the curved surface, the second curved end guides the light to a specific direction or further concentrates. Similar to the function of the first plane end, the second plane end is used to ensure the fit and stable docking between the second light concentrator 42 and other components (such as the first light concentrator 41 or the light guide cavity 40) to ensure the precise output of near-infrared at the second curved end. The function of the second light concentrator 42 is to further optically adjust the light focused by the first light concentrator 41, so that the focus point of the light is more accurate, or to ensure that the light beam does not diffuse too much during transmission. This design makes the entire optical system more efficient and can control light with higher precision and directionality. For example, in the lighting system, the second focusing element 42 can ensure that the light is irradiated to the predetermined area at a specific angle and intensity, avoiding excessive scattering of light, thereby improving the uniformity and intensity of the lighting effect. The first planar end fits with the second planar end. The close fit of the two planar ends can ensure the light transfer efficiency between the first and second focusing elements 42. The contact of the planar ends helps to avoid the loss or deviation of light between the focusing elements and maintain the precise path of the light. Precise docking can also reduce unnecessary reflections or scattering, ensuring that light is transmitted along the correct path. The fitting design ensures that there are no gaps or errors in the optical elements in the optical system, thereby reducing light loss and distortion.The fitting of the two planar ends can improve the optical efficiency of the overall optical system and ensure the efficient conduction and concentration of light. For example, in a laser system, this design ensures that the focused light can pass through the optical element without loss, ensuring the quality and stability of the final output beam. The first arc surface end is arranged on the side of the light guide cavity 40 close to the light emitting part 2, and the second arc surface end is arranged on the side of the light guide cavity 40 away from the light emitting part 2. This design configuration shows that the first light concentrator 41 is responsible for receiving light from the light emitting part 2, and focusing or guiding the light to the second light concentrator 42 through the arc surface end. The second light concentrator 42 receives the light focused by the first light concentrator 41, and further adjusts or finely focuses. Through this division of labor, the two light concentrators work together to make the transmission of light more efficient and accurate. This configuration enables light to be efficiently transmitted between the two light concentrators, and achieves ideal beam characteristics through gradual focusing and adjustment. The light starts from the light emitting part 2, is focused by the first light concentrator 41, and then finely adjusted by the second light concentrator 42 to ensure that the intensity, direction and shape of the final light beam meet the requirements. Through this structural design, the first light concentrator 41 and the second light concentrator 42 cooperate with each other in the light guide cavity 40, which can effectively control and optimize the light path and focusing effect. Specifically, the first light concentrator 41 concentrates the light from the light emitting part 2. The second light concentrator 42 further fine-tunes the light beam. The two are fitted together at the flat ends to ensure that the light path does not deviate.

[0025] like Figure 4As shown, further, the heat dissipation part 5 includes a driving component 50, a first cold air channel 51 and a second cold air channel 52, the driving component 50 is arranged on one side of the light-emitting part 2, the first cold air channel 51 and the second cold air channel 52 are respectively arranged in the main body 1, the first cold air channel 51 is connected to the cavity 20, and the second cold air channel 52 is arranged on the side of the focusing part 4. In this embodiment, the driving component 50 can be set as a fan to drive air flow and promote heat dissipation. The main function of the fan as the driving component 50 is to promote air flow by rotating the fan blades. The fan blades can be set as a soft colloid to reduce the noise of the fan when driving. Its function is to introduce external cold air into the equipment and push the air through the heat dissipation parts 5 (such as heat sinks, cooling pipes, etc.) inside the equipment to take away heat. The speed, airflow and airflow direction of the driving component 50 can be adjusted by the driving system to optimize the heat dissipation effect under different working conditions. The drive assembly 50 may also have a speed regulating function, increasing the airflow at high loads and reducing the airflow at low loads to improve the energy efficiency of the system. The design of the drive assembly 50 can greatly improve the heat dissipation efficiency. It strengthens the air flow so that the heat generated inside the device can be quickly taken away, avoiding heat accumulation and keeping the device at the optimal working temperature. The first cold air channel 51 is connected to the cavity 20, and the air flow is driven by the drive assembly 50 to take away the heat. The connection between the first cold air channel 51 and the cavity 20 means that the cold air driven by the drive assembly 50 can directly enter the cavity 20 inside the device and take away the heat generated by the light-emitting part 2 and the reflecting part 3. The drive assembly 50 helps to dissipate heat more efficiently through air flow, especially in areas where the heat generated when the device is working is more concentrated. By reasonably designing the layout of the drive assembly 50 and the cold air channel, it can ensure that the air flows smoothly through all key components to prevent local overheating. This design can keep the internal temperature of the device at a low level, effectively reduce the temperature of the components, and avoid overheating to damage the components. The second cold air channel 52 is arranged on the side of the focusing part 4 to dissipate the heat generated by the focusing part 4. If the heat accumulation of the focusing part 4 is not dissipated in time, it may affect the performance of the optical system, causing the light beam to deform or the focal length to change. By setting the second cold air channel 52 around the focusing part 4, the heat generated by the focusing part 4 is quickly taken away. This design can ensure that the optical accuracy of the focusing part 4 is not affected by overheating when working at high power, and at the same time ensure that the cold air flows to the heat dissipation elements around the focusing part 4, such as heat sinks or heat pipes, to improve the heat dissipation effect. A reflector 401 is set on the inner circumference of the light guide cavity 40.

[0026] like Figure 4As shown, further, a heat dissipation outlet 6 is provided on the side of the main body 1 away from the driving assembly 50, which is used to supply the first cold air channel 51 and the second cold air channel 52 with airflow after heat dissipation. The main body 1 is also provided with an air inlet 7, and a dustproof net is provided on the air inlet 7; when the driving assembly 50 starts working, the external airflow enters the main body 1 from the air inlet 7, and the airflow is respectively sent to the first cold air channel 51 and the second cold air channel 52 through the driving assembly 50. In this embodiment, the heat dissipation outlet 6 is designed on the side of the main body 1 away from the driving assembly 50, the purpose is to ensure that the air after heat dissipation can be discharged smoothly by optimizing the airflow path. The first cold air channel 51 and the second cold air channel 52 are responsible for introducing cold air into the equipment, and after the heat is taken away by the airflow, the hot air is discharged through the heat dissipation outlet 6. The function of the heat dissipation outlet 6 is to directly discharge the airflow that has taken away the heat, prevent the hot air from being retained inside the equipment, and affect the overall heat dissipation efficiency. The hot air is effectively discharged through the heat dissipation outlet 6, avoiding the accumulation of airflow inside the equipment, thereby improving the heat dissipation capacity of the equipment. The air flow inside the device is optimized to ensure that heat can be discharged quickly, which helps to maintain the temperature stability of the device, improve the overall heat dissipation effect and the stable operation of the device. The air inlet 7 is located on the main body 1 of the device and is the channel for cold air to enter the device. The external airflow enters the inside of the device through the air inlet 7, and the drive component 50 cools by guiding the air to the cold air channel. The setting of the dustproof net effectively filters dust and impurities in the air, prevents these particles from entering the inside of the device, protects the internal components of the device from being blocked or damaged by dust, and maintains the normal operation of the cooling system. The design of the air inlet 7 ensures the effective entry of cold air and ensures that the cooling system has enough air flow to take away the heat inside the device. The dustproof net plays a protective role, prevents dust from entering the inside of the device, keeps the cold air channel unobstructed, prevents poor heat dissipation or damage to internal components, and enhances the long-term stability and reliability of the device. The airflow is sent to the first cold air channel 51 and the second cold air channel 52 respectively through the drive component 50. The drive component 50 is the core part of the airflow inside the device. When the drive assembly 50 is started, external air enters the device through the air inlet 7, and the function of the drive assembly 50 is to distribute the air into two cold air channels. The drive assembly 50 is a fan or similar device that can promote air flow during operation and guide the air to the first cold air channel 51 and the second cold air channel 52 according to cooling requirements. The first cold air channel 51 and the second cold air channel 52 are respectively responsible for guiding the cold air to different parts of the device to take away the heat. The drive assembly 50 effectively distributes the airflow to ensure that the cold air can accurately cover all parts of the device, maximize the heat removal, and thus optimize the heat dissipation effect. This setting helps to ensure that the device always has sufficient cold air supply during operation, prevent the device from overheating and maintain normal operating temperature. The function of the first cold air channel 51 and the second cold air channel 52 is to guide air to different parts of the device that need to be cooled.The first cold air channel 51 and the second cold air channel 52 may be responsible for the heat dissipation requirements of different areas of the device, respectively, to ensure that the cold air can cover key components, such as processors, electronic components, etc. After the drive component 50 guides the air to the two channels, the cold air will flow in them and take away the heat, and then the hot air will be discharged from the device through the heat dissipation outlet 6. Through the rationally designed cold air channel layout, it is ensured that the heat of each part of the device is evenly processed to avoid local overheating or insufficient heat dissipation. This sub-channel design helps to optimize the air flow distribution and cooling efficiency, improve the heat dissipation effect of the device, and ensure that the device maintains a constant temperature during operation and prolongs its service life. The external airflow enters the device through the air inlet 7, and is sent to the first cold air channel 51 and the second cold air channel 52 respectively through the action of the drive component 50, taking away the heat and discharging through the heat dissipation outlet 6. The design of the overall airflow path starts from the external air inlet 7. After the cold air enters the device, it is guided by the drive component 50 and enters the two cold air channels. The function of the cold air channel is to guide the air to the area inside the device that needs to be cooled and take away the generated heat. Finally, the cooled hot air is discharged from the device through the heat dissipation outlet 6. Through the optimized airflow path, cold air can efficiently remove heat, improve the heat dissipation effect, and ensure the stability of the internal temperature of the equipment. The smooth flow of air not only ensures effective heat dissipation, but also avoids hot air stagnation or local overheating and realizes the distinction between hot and cold airflow paths, improving the overall performance and reliability of the equipment.

[0027] like Figure 5As shown, further, a reflective layer and a barrier layer are provided on the inner side wall of the cavity 20, the reflective layer is provided on the side of the inner side wall of the cavity 20 close to the light emitting part 2, and the barrier layer is provided on the side of the inner side wall of the cavity 20 away from the light emitting part 2, and the barrier layer is used to block the heat in the cavity 20 and block the near-infrared light in the cavity 20. In this embodiment, the function of the reflective layer is to reflect the light inside the cavity 20, especially the light emitted by the light emitting part 2. Generally, the reflective layer uses a material with high reflectivity (such as aluminum, silver or a special coating) to ensure that the light is not wasted or lost, but reflected back into the cavity 20, further enhancing the light utilization efficiency. The reflective layer is usually a smooth and reflective surface, which is located on the side wall closer to the light source, and the purpose is to capture and reflect the light generated by the light emitting part 2, thereby improving the light output of the device. Enhance the light utilization of the light emitting part 2 and improve the lighting or display effect. After reflection, the light can be more evenly distributed in the cavity 20, thereby improving the lighting efficiency of the entire system. The reflective layer helps to reduce the loss of light, so that more light can be concentrated on the area that needs to be illuminated or output through the lens system, thereby improving the overall performance of the system. The barrier layer is located on the side of the inner wall of the cavity 20 away from the light-emitting part 2. The barrier layer can be composed of a material with thermal isolation properties (such as ceramics, thermal insulation film, or a material with reflective and absorptive properties) to effectively isolate the heat and infrared light in the cavity 20. The barrier layer slows down the diffusion of heat in the cavity 20 by means of heat insulation or heat absorption, avoids the heat from being concentrated in the area where it is not desired to accumulate, and cooperates with the first cold air channel 51 to dissipate the heat in the cavity 20. In addition, the barrier layer also has the function of shielding near-infrared light, preventing the near-infrared light in the cavity 20 from escaping from the cavity 20. Therefore, by blocking the near-infrared light, it helps to control the temperature and reduce the impact on other components of the system. By effectively isolating heat. Through the synergistic effect of the reflective layer and the barrier layer, the light efficiency and thermal efficiency of the entire system are optimized. The device can more efficiently utilize the light generated by the light-emitting part 2, while effectively isolating excess heat and unnecessary light, and maintaining the stability and reliability of the system. This design prevents the device from performing poorly due to excessive heat buildup or light waste when operating for long periods of time, thus enhancing the overall efficiency and life of the device.

[0028] like Figure 2As shown, further, the reflecting part 3 includes a fixed bracket 30 and a reflecting sheet 31, the fixed bracket 30 is arranged in the cavity 20, the light-emitting part 2 is arranged on the fixed bracket 30, and the reflecting sheet 31 is arranged on one side of the fixed bracket 30, and the fixed bracket 30 and the reflecting sheet 31 are respectively provided with an inclination angle, which is used to reflect the near-infrared light generated by the light-emitting part 2 to the focusing part 4. In this embodiment, the reflecting part 3 is composed of a fixed bracket 30 and a reflecting sheet 31. The main function of the reflecting part 3 is to reflect near-infrared light. The reflection principle is based on the law of reflection, that is, the incident light and the reflected light are symmetrical about the normal of the reflecting surface. In this system, the reflecting part 3 realizes the reflection of the light emitted by the light-emitting part 2 through the fixed bracket 30 and the reflecting sheet 31, and helps to direct the light to the focusing part 4. The fixed bracket 30 is located inside the cavity 20, and is used to support the light-emitting part 2 and the reflecting sheet 31. The function of the fixed bracket 30 is to provide a stable support structure for the light-emitting part 2 and the reflective sheet 31, and the fixed bracket 30 is also provided with a reflective surface to enhance the reflective effect. The design of the bracket should ensure that the relative position of the light-emitting part 2 and the reflective sheet 31 remains stable and can meet the path requirements of the reflected light. The reflective sheet 31 is an important component of the reflective part 3 and is located on one side of the fixed bracket 30. The function of the reflective sheet 31 is to reflect the near-infrared light emitted by the light-emitting part 2. The reflective sheet 31 is usually made of a material with high reflectivity (such as aluminum alloy, silver, etc.), and its surface design is usually a mirror-like shape or a shape with a specific curvature to ensure that the light can be effectively reflected to the focusing part 4. Factors such as the angle, material and surface treatment of the reflective sheet 31 will affect the reflection effect of the light. The function of the light-emitting part 2 is to generate near-infrared light and emit it to the reflective part 3. The working principle of the light-emitting part 2 is usually based on the phenomenon that light emission occurs when current passes through a semiconductor material or other light-emitting material. In near-infrared light applications, the light-emitting part 2 specifically selects light that can emit a specific wavelength (usually the near-infrared light peak is 990nm). The fixed bracket 30 and the reflector 31 have a tilt angle respectively. The tilt angle is set to control the reflection path of the emitted near-infrared light. The direction of the reflected light is related to the tilt angle of the reflective surface, and the reflection angle is equal to the incident angle. By adjusting the tilt angles of the fixed bracket 30 and the reflector 31, it can be ensured that the light emitted by the light-emitting part 2 is reflected in a predetermined direction and finally converged to the focusing part 4. The design of the tilt angle is crucial to improving the efficiency of the system, and can accurately direct light energy to a specified area. The focusing part 4 is a component for receiving the reflected light and focusing it. The function of the focusing part 4 is to concentrate the near-infrared light reflected from the reflective part 3 at a point or a small area for subsequent processing or utilization. The design of the focusing part 4 usually includes a lens, a reflector or other optical elements, and the focusing of the light is achieved by using the optical convergence principle (for example, a convex lens focuses parallel light rays to a focal point).

[0029] like Figure 4 As shown, further, a fixed structure 8 is provided in the main body 1 for fixing the cavity 20, and the fixed structure 8 is used to separate the first cold air channel 51 and the second cold air channel 52. The fixed structure 8 is used to fix the cavity 20, and to achieve physical isolation inside the cavity 20, dividing different channels (here, the cold air channels). Specifically, the fixed structure 8 divides the space inside the cavity 20 into two parts, namely the first cold air channel 51 and the second cold air channel 52. The fixed structure 8 is made of a solid material, and its design is usually to have a certain thickness and strength to ensure that no deformation or displacement occurs during the air flow in the channel. By separating the first cold air channel 51 and the second cold air channel 52 through the fixed structure 8, the cold air flows in the two channels can be effectively prevented from interfering with or mixing each other. This design can ensure that the flow direction and flow rate of the cold air in each channel are well controlled, thereby improving the cooling efficiency. In addition, separating the cold air channels can reduce the uneven cooling effect caused by the temperature difference and pressure changes in different channels, thereby optimizing the overall heat dissipation performance. Isolation ribs 11 are also provided in the main body 1 to separate the air inlet 7 from the cold air channel, so as to separate the incoming cold air from the hot air after heat dissipation, thereby effectively avoiding interference or mixing between the cold air and hot air flows in the channel.

[0030] like Figure 3 As shown, further, a filter 9 is arranged between the light-guiding cavity 40 and the cavity 20. The filter 9 arranged between the light-guiding cavity 40 and the cavity 20 is an optical element used to filter out light outside a specific wavelength range. The wavelength range of this filter 9 is 680-1800nm, which means that it can transmit light within this wavelength range and filter out light below 680nm (ultraviolet and visible light regions) and above 1800nm ​​(infrared light region). The filter 9 can filter out light within an unnecessary wavelength range, reduce the interference of stray light, and ensure the optical performance of the system and the purity of the signal. By removing unnecessary wavelength light, the filter 9 can improve the signal-to-noise ratio of the system, make the received signal cleaner, and reduce the noise caused by light of unnecessary wavelengths.

[0031] like Figure 3 As shown, in one embodiment, in the driving assembly 50, by using a low-noise turbine fan, the cold air is divided through multiple channels and passes through the cavity 20 and the light guide cavity 40. Through testing, the air volume of the cold air may be between 20-40L / min. This air volume range can ensure good heat dissipation without affecting noise control.

[0032] like Figure 3As shown, in one embodiment, the maximum power of the light emitting part 2 is 200W, and it may include a lamp tube, and more than 98% of the light waves emitted by the lamp tube pass through the 680nm-1800nm ​​filter 9 into the total reflection light guide cavity 40, ensuring the effective transmission of light energy. The light transmittance of the filter 9 is extremely high, especially in the range of 680nm-1800nm, which can ensure sufficient light energy output, so that the physical therapy device can be suitable for treatment at a depth of 4-10cm below the skin.

[0033] like Figure 2 As shown, in another embodiment, the main body 1 also includes a control terminal 10, and the control terminal 10 can detect the temperature parameters in the cavity 20 in real time. When the temperature parameters of the cavity 20 exceed 90°C and the temperature of the first focusing element 41 and the second focusing element 42 exceeds 55°C, the system will automatically shut down the energy output.
