[0050] The utility model provides a light source heat dissipation assembly 10 suitable for being assembled in a housing of a treatment head 1 .

[0051] Combination Figure 1 and Figure 2 As shown, in one embodiment of the utility model, the light source heat dissipation assembly 10 includes a heat sink 11, a light-emitting device 12 and a mounting seat 13; the light-emitting device 12 is attached to the surface of the heat sink 11 and is used to generate the light source required for treatment; the heat sink 11 is installed on the mounting seat 13, the heat sink 11 presses the light-emitting device 12 in the mounting seat 13, and the mounting seat 13 and the heat sink 11 are detachably connected.

[0052] In this embodiment, the light emitting device 12 is a high-power LED, and the light emitting device 12 can emit two different wavelengths of light: 590nm and 830nm, to achieve different therapeutic effects. Of course, during the light emitting period, it can also be set to emit a variety of different wavelengths of light, and the wavelength is not limited to 590nm and 830nm. Different light emitting wavelengths can be selected according to treatment needs.

[0053] Since the light emitting device 12 has a relatively high power and light therapy generally lasts for a period of time, the continuous operation of the light emitting device 12 will generate more heat. During the light emitting period, the light emitting device 12 is attached to the surface of the heat sink 11 and is firmly combined with the heat sink 11 through materials such as thermal conductive silicone or thermal conductive grease or mechanical connections, so that the generated heat can be efficiently transferred to the heat sink 11.

[0054] The radiator 11 is made of aluminum or copper and has good thermal conductivity. The radiator 11 is designed to have a structure with multiple heat dissipation fins, which increases the heat dissipation surface area and improves the heat dissipation efficiency. A heat dissipation cavity can also be set inside the radiator 11, and a heat conductive material can be filled in the heat dissipation cavity to improve the heat dissipation efficiency. The mounting seat 13 is made of plastic material and is connected to the housing of the treatment head 1 by screws or buckles to achieve quick disassembly and assembly.

[0055] The mounting base 13 is used to fix the heat sink 11 and the light-emitting device 12. The mounting base 13 and the heat sink 11 can be connected in a snap-on, threaded or plug-in manner. The light-emitting device 12 is arranged between the heat sink 11 and the mounting base 13. After the heat sink 11 and the mounting base 13 are fixedly connected, the heat sink 11 presses against the light-emitting device 12 to fix the light-emitting device 12 between the heat sink 11 and the mounting base 13. This method of fixing the light-emitting device 12 improves the convenience of assembling the light-emitting device 12.

[0056] The present application forms a whole by combining the heat sink 11, the light-emitting device 12 and the mounting base 13, and then assembles the whole into the outer shell of the treatment head 1. Compared with the prior art method of assembling the light-emitting device 12 and the heat sink into the outer shell of the treatment head 1 respectively and then fixing the light-emitting device 12 and the heat sink to the outer shell of the treatment head 1 respectively, the technical solution of the present application can improve the assembly accuracy between the various components of the light source heat dissipation assembly 10, as well as the convenience and efficiency of assembling the light source heat dissipation assembly 10 with the outer shell of the treatment head 1.

[0057] Combination Figure 1 and Figure 2 As shown, in one embodiment of the present utility model, the light emitting device 12 includes a flexible circuit board 122 and a light emitting element 123;

[0058] The light emitting element 123 is disposed on a surface of the flexible circuit board 122 facing away from the heat sink 11 . A flexible connecting end 122 a is extended from one side of the flexible circuit board 122 . The flexible connecting end 122 a is used to connect to the external control board 70 .

[0059] In this embodiment, the flexible circuit board 122 is made of polyimide material, which has good flexibility and high temperature resistance, and a circuit is arranged thereon to drive the light-emitting element 123 to work. The light-emitting element 123 is an LED lamp bead, which is arranged on the surface of the flexible circuit board 122 away from the heat sink 11. The light-emitting element 123 has a plurality of lamp beads, and the arrangement of the plurality of lamp beads can be adjusted according to the shape of the treatment head 1 and the treatment area to achieve uniform or specific mode of illumination.

[0060] The flexible connection end 122a has a spring pin or a crimping terminal for connecting to an external control board 70 to control the light source. In this embodiment, the circuit control board 70 for controlling the light emission of the light emitting element 123 is designed as a flexible circuit control board 70, which reduces the volume of the circuit control board 70. The circuit control board 70 can be folded to adapt to complex installation environments, thereby improving space utilization and compactness of the structure.

[0061] Combination Figure 2 As shown, in one embodiment of the present utility model, the light emitting device 12 further includes a hard substrate 121;

[0062] The hard substrate 121 is attached to a surface of the heat sink 11 facing the mounting base 13 , and the flexible circuit board 122 is disposed on a side of the hard substrate 121 away from the heat sink 11 .

[0063] In this embodiment, the hard substrate 121 can be a metal substrate or a ceramic substrate, etc., which has high mechanical strength and good thermal conductivity. The hard substrate 121 is attached to the surface of the heat sink 11 facing the mounting seat 13 to provide support and protection for the flexible circuit board 122. The flexible circuit board 122 is arranged on the side of the hard substrate 121 away from the heat sink 11 to improve the heat dissipation efficiency of the light-emitting element 123 to the heat sink 11. The shape of the hard substrate 121 is adapted to the flexible circuit board 122 to increase the contact area between the flexible circuit board 122 and the hard substrate 121.

[0064] A thermally conductive silicone pad 14 is also arranged between the hard substrate 121 and the heat sink 11. Since the hard substrate 121 and the heat sink 11 are relatively rigid, deformation and pits are inevitably present on the surface. Therefore, the thermally conductive silicone pad 14 is arranged between the hard substrate 121 and the heat sink 11. The thermally conductive silicone pad 14 with good flexibility and thermal conductivity can have a larger contact area with the surface of the hard substrate 121 and the heat sink 11, thereby improving the heat dissipation efficiency from the hard substrate 121 to the heat sink 11.

[0065] Combination Figure 1 and Figure 3 As shown, in one embodiment of the utility model, a limiting plate 134 is provided on the side of the mounting seat 13 facing the light-emitting device 12, the limiting plate 134 is arranged around the outer periphery of the mounting seat 13, the light-emitting device 12 is arranged in a limiting groove 23 formed by the limiting plate 134, the limiting plate 134 is provided with an avoidance opening 135, and the flexible connection end 122a extends from the avoidance opening 135 to the outside of the mounting seat 13.

[0066] In this embodiment, the limiting plate 134 forms a limiting groove 23 around the outer periphery of the mounting seat 13 for fixing the light emitting device 12. The shape and size of the limiting groove 23 match the shape and size of the light emitting device 12, so that the light emitting device 12 can be accurately positioned through the limiting groove 23.

[0067] The setting of the limiting plate 134 not only ensures that the light emitting device 12 is stably positioned in the mounting seat 13, but also the avoidance opening 135 provided thereon facilitates the flexible connection end 122a to extend to the outside of the mounting seat 13 and connect to the external control board 70, thereby ensuring the convenience of electrical connection. Since the flexible circuit board 122 is located on the side of the hard substrate 121 facing the mounting seat 13, that is, when the light emitting device 12 is limited in the limiting groove 23, the flexible circuit board 122 abuts against the bottom of the limiting groove 23, so the setting of the avoidance opening 135 avoids the problem of excessive bending of the flexible connection end 122a of the flexible circuit board 122 at the bottom of the limiting groove 23, thereby improving the reliability of the flexible circuit board 122.

[0068] Combination Figure 2 and Fig. 9 As shown, in one embodiment of the present utility model, the light source heat dissipation assembly 10 further includes a temperature sensor 124;

[0069] The temperature sensor 124 is disposed on the surface of the flexible circuit board 122 and is used to detect the temperature of the light emitting device 12 .

[0070] In this embodiment, the temperature sensor 124 is arranged on the surface of the flexible circuit board 122 and is close to the light emitting device 12, and is used to monitor and control the temperature of the light emitting device 12 in real time. The temperature sensor 124 can be a component such as a PTC, an NTC thermistor or a thermocouple, which can accurately measure and feedback the operating temperature of the light emitting device 12.

[0071] At the same time, the temperature sensor 124 is connected to the external control board 70 through the flexible circuit board 122, and the data of the temperature sensor 124 can be read and analyzed in real time, thereby realizing overheat protection of the light emitting device 12. When the temperature of the light board of the treatment head 1 reaches the set temperature, the flexible circuit board 122 disconnects the electrical connection with the light emitting device 123, and the treatment head 1 stops treatment, preventing the user from being scalded by excessive temperature, and effectively ensuring the safety and effectiveness of user use.

[0072] Combination Figure 3 As shown, in one embodiment of the present invention, the mounting base 13 is provided with a light outlet 132 , the light emitting device 12 is located between the heat sink 11 and the mounting base 13 , and the light emitted by the light emitting device 12 is emitted through the light outlet 132 .

[0073] In this embodiment, the light outlet 132 is located in the middle of the mounting seat 13. When the limiting groove 23 is provided on the periphery of the mounting seat 13, the light outlet 132 is located at the bottom of the limiting groove 23, that is, the cross section of the mounting seat 13 is annular. The light emitting device 12 is attached to the surface of the mounting seat 13, and the light emitting member 123 in the light emitting device 12 is exposed at the light outlet 132, so that the light emitted by the light emitting device 12 is emitted from the light outlet 132.

[0074] The shape and size of the light outlet 132 are designed according to the light emitting angle and light spot shape of the light emitting device 12 and the relative position of the light emitting element 123 and the mounting base 13. The light outlet 132 can be circular, square, etc., and the edge of the light outlet 132 is designed with a chamfer to reduce light scattering and improve light focusing.

[0075] Combination Figures 1 to 3 As shown, in one embodiment of the present invention, the heat sink 11 is provided with a slot 112 , and the mounting seat 13 is provided with a hook 131 facing the heat sink 11 , and the hook 131 is locked in the slot 112 so that the mounting seat 13 and the heat sink 11 are detachably connected.

[0076] In this embodiment, the slot 112 has a certain depth, and the slot wall of the slot 112 is inclined or the side of the hook 131 is inclined, so as to facilitate the insertion and fixation of the hook 131. The shape and size of the hook 131 are precisely matched with the slot 112, ensuring the tightness and reliability of the connection. The material of the hook 131 is selected to have high strength and wear resistance, such as stainless steel or hard plastic, to resist wear and deformation in long-term use.

[0077] In addition, two hooks 131 and two slots 112 are provided and are respectively located on opposite sides of the mounting base 13 and the heat sink 11 . Each hook 131 cooperates with a slot 112 to improve the connection strength between the mounting base 13 and the heat sink 11 .

[0078] Furthermore, a groove is provided on the side of the radiator 11, and the groove is located on the side of the radiator 11 close to the mounting seat 13, and the clamping groove 112 is provided at the bottom of the groove. The clamping hook 131 is connected to the mounting seat 13 through a cantilever, and when the mounting seat 13 is engaged with the radiator 11, the cantilever is limited in the groove, the clamping hook 131 is clamped in the clamping groove 112, and the outer side surface of the cantilever is flush with the outer side surface of the mounting seat 13 and the outer side surface of the radiator 11. Therefore, after the mounting seat 13 and the radiator 11 are assembled, the mounting seat 13 is flush with the surface of the radiator 11, and the clamping hook 131 is hidden inside the structure, which improves the overall aesthetics and the convenience of assembly with the outer shell of the treatment head 1.

[0079] Combination Figure 4 As shown, in one embodiment of the present utility model, the heat sink 11 includes a heat sink box 114, a cover plate 113 and a heat conducting member;

[0080] The heat dissipation box 114 forms a cavity 111 with an opening. The heat conduction member is a high heat conductive material such as antifreeze or paraffin, and is filled in the cavity 111 . The cover plate 113 covers the opening of the heat dissipation box 114 .

[0081] In this embodiment, the heat dissipation box 114 and the cover plate 113 are generally made of aluminum alloy or copper alloy, which are excellent in thermal conductivity. The high thermal conductivity material filled in the cavity 111 not only improves the heat conduction efficiency, but also increases the heat dissipation area, thereby effectively reducing the operating temperature of the light emitting device 12.

[0082] The cover plate 113 and the heat dissipation box 114 can be connected by threaded connection, welding, etc. When the cover plate 113 and the radiator 11 are threadedly connected, a seal is provided between the cover plate 113 and the radiator 11 to improve the sealing effect of the cavity 111.

[0083] The utility model also proposes a treatment head 1, which includes a shell 20, a light-transmitting mirror 30 and a light source heat dissipation assembly 10. The specific structure of the light source heat dissipation assembly 10 refers to the above embodiment. Since the treatment head 1 adopts all the technical solutions of all the embodiments of the above light source heat dissipation assembly 10, it at least has all the beneficial effects brought by the technical solutions of the above embodiments, which will not be repeated here one by one.

[0089] The size and shape of the limiting platform 22 are precisely matched with the periphery of the light-transmitting mirror 30, so that the middle of the light-transmitting mirror 30 abuts against the part of the limiting platform 22 located at the window 21 to achieve the best matching effect.
