[0002] At present, medical beauty products have many functions and the number of internal heating elements has increased. For example, multiple types of energy output devices with ultrasonic output, radio frequency output, and electrical stimulation output need to be installed with different energy source output devices. When multiple energy source output devices are integrated into the handle, the number of heat sources inside the handle increases, and the heat generated by the handle also increases relatively quickly. Therefore, the device may not be able to meet the needs of long-term use. However, based on a complete treatment, the device needs to be used continuously to complete the entire course of treatment. If the temperature is too high and the device is shut down, the course of treatment may be interrupted. Multiple uses are required to complete the complete treatment, and the entire treatment cycle is relatively long. At the same time, the treatment device generates high heat during use, causing the handle shell to rise in temperature. The user will feel hot when holding it, resulting in a reduced user experience. In addition, if the temperature is too high, it may not meet the relevant product safety standards. Utility Model Content

[0036] The utility model provides a heat dissipation handle 100, which is intended to enable a high-power therapeutic apparatus to meet relevant safety standards.

[0037] In the embodiment of the present utility model, in combination with reference to Figures 1 to 4 The heat dissipation handle 100 includes a shell 10, a fan 20 and a heating component 30. The shell 10 is provided with an air inlet 11 and an air outlet 12. The fan 20 is installed inside the shell 10. The fan 20 is used to drive air to flow from the air inlet 11 to the air outlet 12 in the shell 10. The heating component 30 is installed inside the shell 10 and is located between the air inlet 11 and the air outlet 12.

[0038] It can be understood that the heating component 30 is generally an integrated circuit board in a common smart device, on which various functional components are soldered, such as a microcontroller MCU or an application-specific integrated circuit AS. IC, etc., when the therapeutic device is started, the heating component 30 inside the heat dissipation handle 100 is powered on and starts to work. The functional elements on the heating component 30 will inevitably generate heat when working. Therefore, the heating component 30 is installed inside the heat dissipation handle 100 and is located between the air inlet 11 and the air outlet 12, so that when the fan 20 rotates, it drives the air to enter from the air inlet 11 and then blow out from the air outlet 12, which is equivalent to forming an air duct inside the heat dissipation handle 100 and between the air inlet 11 and the air outlet 12. The heating component 30 is located in the air duct, and the air flowing in the air duct absorbs the heat generated by the heating component 30. Finally, the heat flows out of the heat dissipation handle 100 from the air outlet 12 with the air flow, thereby avoiding excessive heat accumulation inside the heat dissipation handle 100, resulting in excessive temperature on the outer surface of the handle, so that the high-power therapeutic device meets the relevant safety standards; and avoids the problem that the therapeutic device cannot be used for a long time due to excessive temperature of the therapeutic device, effectively increases the use time of the therapeutic device, and shortens the treatment time.

[0039] In some embodiments, the shell 10 is cylindrical in shape, the air inlet 11 is located at one end of the shell 10, and the air outlet 12 is located at the other end of the shell 10. The fan 20 inside the shell 10 rotates to draw air in from the air inlet 11 and then blow the air out from the air outlet 12. In this way, the air intake of the air inlet 11 is relatively large, and the heating component 30 can be exposed to more air. In this way, the fan 20 has a better cooling effect on the heating component 30.

[0040] In other embodiments, the shell 10 is in the shape of a flat rectangular parallelepiped, the air inlet 11 is located on a surface with a larger area, the air outlet 12 is located at one end of the shell 10, and the fan 20 is installed at the air inlet 11. When the fan 20 rotates, due to the relatively large area of ​​the air inlet 11, the amount of air entering the shell 10 is relatively large, and the area of ​​the air outlet 12 is relatively small. After entering the shell 10, the air can repeatedly contact the heating component 30, and then the airflow absorbs more heat from the heating component 30, which improves the heat dissipation efficiency of the heat dissipation handle 100.

[0041] In some other embodiments, the fan 20 may be a common small, low-noise, high-efficiency DC micro fan.

[0042] Further, see Figure 1 In one embodiment, the air inlet 11 is located on the side wall of the shell 10 , and the air inlet 11 is close to the first end of the shell 10 , and the air outlet 12 is located at the second end of the shell 10 .

[0043] It can be understood that the first end of the shell 10 is the top of the shell 10. The top of the shell 10 is provided with a connection port, which can be connected to the treatment head. The treatment head and the heat dissipation handle 100 are detachably connected, wherein the treatment head can have a variety of specifications, such as a light treatment head, a radio frequency treatment head, an ultrasonic treatment head, etc. The second end of the shell 10 is the bottom of the shell 10. The bottom is provided with an interface, which can be directly connected to an external power source; or a battery is provided in the heat dissipation handle 100, and an external charger can be used to charge the heat dissipation handle 100 through the interface located at the bottom of the shell 10. In this way, the air inlet 11 is equivalent to being set near the top of the shell 10, and the air outlet 12 is equivalent to being set near the bottom of the shell 10. The air duct is relatively long, and the amount of air flowing through the heating component 30 is more, thereby absorbing more heat from the heating component 30.

[0044] In some embodiments, in order to meet the customer's usage habits of the heat dissipation handle 100, the air inlet 11 is set in the shape of a long hole, and the extension direction of the long hole extends along the circumference of the shell 10. In this way, the air inlet 11 ensures that its area is relatively large, thereby increasing the air intake and preventing the user from covering the air inlet 11 when holding the heat dissipation handle 100.

[0045] Further, see Figure 4 In one embodiment, the fan 20 is disposed relatively close to the air outlet 12 .

[0046] In this way, the fan 20 is arranged close to the air outlet 12, so that when the fan rotates, a better negative pressure environment can be formed, which is conducive to the external air entering the interior of the shell 10 through the air inlet 11, and is more easily discharged from the air outlet 12. When the air flows inside the shell, the heat generated by the heating component 30 will be carried away by the flowing air, avoiding overheating of the therapeutic device, effectively extending the use time of the therapeutic device, and ensuring a comfortable body temperature when holding the handle.

[0047] In this embodiment, the fan 20 is arranged along the direction of the air duct between the air inlet 11 and the air outlet 12, so that the direction of the air flow driven by the fan 20 is consistent with the direction of the air duct, thereby improving the flow efficiency of the airflow driven by the fan 20.

[0048] Further, see Figure 1 In one embodiment, two air inlets 11 are provided, and the two air inlets 11 are symmetrically distributed on two opposite sides of the shell 10; and / or, the air outlet 12 includes a plurality of small holes 121, and the plurality of small holes 121 are evenly arranged at the second end of the shell 10.

[0049] It should be noted that the two opposite side surfaces of the shell 10 where the air inlets 11 are distributed are two symmetrical side surfaces located in the circumferential direction of the first end of the shell 10 , which are different from the two ends mentioned above.

[0050] In this way, two air inlets 11 are provided and symmetrically distributed at the two ends of the shell 10, so that when the air enters the shell 10, two symmetrical airflows are also formed. The two symmetrical airflows absorb the heat from the two ends of the heating component 30 respectively, further improving the heat dissipation efficiency. At the same time, the air outlet 12 is provided with a plurality of small holes 121, which can speed up the rate at which hot air is discharged from the inside of the shell 10.

[0051] In some embodiments, in order to prevent impurities from entering the shell 10 through the air inlet 11 and the air outlet 12 and affecting the normal operation of the heating component 30, filters are provided at the air inlet 11 and the air outlet 12. The filters can filter larger particles of dust, hair balls, small debris and other debris to prevent them from entering the shell 10 and contacting the heating component 30, causing the heating component 30 to short-circuit.

[0052] Further, see Figure 3 In one embodiment, the heat dissipation handle 100 further includes a heat insulating member 40 , which is located between the heating component 30 and the shell 10 , and the heat insulating member 40 is in contact with the inner wall of the shell 10 .

[0053] In this way, the heat insulating member 40 is arranged inside the shell 10 and fits with the inside of the shell 10. The heat insulating member 40 can isolate the heat generated by the heating component 30 inside the shell 10, so that the temperature of the surface of the shell 10 will not rise rapidly, thereby reducing the temperature of the outer surface of the heat dissipation handle 100.

[0054] In some embodiments, the material of the thermal insulation member 40 may be aerogel, which has low thermal conductivity and low density, so that attaching aerogel to the inner wall of the shell 10 can both minimize the weight of the heat dissipation handle 100 and provide a better thermal insulation effect.

[0055] In other embodiments, the material of the thermal insulation member 40 can be commonly used thermal insulation foam, that is, a foam board is pasted on the inner wall of the shell 10, which can reduce the production cost of the thermal insulation member 40 and further reduce the production cost of the heat dissipation handle 100.

[0056] Further, see Figure 3 In one embodiment, the heat dissipation handle 100 includes a heat conductive member 50 , and the heat conductive member 50 is attached to the surface of the heat generating component 30 .

[0057] In this way, the heat conductor 50 is attached to the surface of the heating component 30. One side of the heat conductor 50 absorbs the heat of the heating component 30, and the other side contacts the airflow and is thus absorbed by the airflow. The heat generated by multiple components of the heating component 30 is concentrated on the heat conductor 50, and the heat is dissipated centrally by the heat conductor 50, thereby improving the heat dissipation efficiency.

[0058] In some embodiments, the material of the heat conductor 50 can be graphite. Graphite has strong thermal conductivity, and its layered structure enables heat to be quickly transferred in a two-dimensional plane, thereby being able to quickly conduct heat from one area to another. Graphite has good flexibility and machinability, and can be processed into complex shapes to suit various heat dissipation needs. At the same time, graphite has strong stability and is not easy to react chemically with most substances. Therefore, it can maintain good performance in various environments, extending its service life and application range. Therefore, choosing graphite as the material of the heat conductor 50 can meet multiple usage requirements at the same time.

[0059] Further, see Figure 4 In one embodiment, the heating component 30 includes a main control circuit board 31 and a driving circuit board 32. The main control circuit board 31 is installed close to the inner wall of the shell 10, and the driving circuit board 32 is installed at the inner center of the shell 10. The main control circuit board 31 is electrically connected to the driving circuit board 32, and the main control circuit board 31 is used to send a control signal to the driving circuit board 32.

[0060] It is understandable that, since the heat generation of the main control circuit board 31 is relatively small, the main control circuit board 31 can be installed on the inner side wall of the housing 10, and the main control circuit board 31 can be electrically connected to the driving circuit board 32, and the main control circuit board 31 is used to send a control signal to the driving circuit board 32 to control the driving circuit board 32 to output energy signals of different types, powers, and frequencies. The relative heat generation of the main control circuit board 31 is less than the heat generation of the driving circuit board 32, so the heat conductor 50 can only be attached to the surface of the driving circuit board 32 to improve the heat extraction efficiency of the driving circuit board 32, and at the same time, under the condition of ensuring the size of the heat dissipation handle 100, the airflow only needs to blow through the upper surface of the main control circuit board 31, and the effect is achieved through single-sided heat dissipation. The driving circuit board 32 can include an ultrasonic module, a radio frequency module, an electrical stimulation module, etc., which can output a variety of energy signals and generate more heat, so the driving circuit board 32 is installed in the center of the housing 10, and both sides of the driving circuit board 32 have airflow passing through to ensure good heat dissipation.

[0061] In some embodiments, the upper surface of the main control circuit board 31 is arranged opposite to one side of the driving circuit board 32, so that when the airflow flows through the surface of the driving circuit board 32, it can also flow through the upper surface of the main control circuit board 31 at the same time, so that a part of the air away from the surface of the driving circuit board 32 can absorb the heat of the main control circuit board 31, thereby improving the utilization rate of the air.

[0062] Further, see Figure 4In one embodiment, the driving circuit board 32 is located between the main control circuit board 31 and the shell 10, and the driving circuit board 32 is spaced apart from the main control circuit board 31 and the shell 10 respectively; wherein a first air duct is formed between the main control circuit board 31 and the driving circuit board 32; and a second air duct is formed between the driving circuit board 32 and the shell 10.

[0063] It should be noted that the driving circuit board 32 is located at the center of the shell 10, and the main control circuit board 31 and the driving circuit board 32 are arranged at intervals. The fan 20 can drive the air flow in the first air duct and the second air duct at the same time, so that the air can enter the shell 10 from the air inlet 11, and pass through the first air duct and the second air duct, as well as the fan 20, and then flow out from the air outlet 12.

[0064] In one embodiment, the air inlet 11 can be connected to the first air duct and the second air duct respectively, and the air can enter the interior of the shell through the air inlets 11 located on opposite sides of the shell 10. In this way, after the air enters the interior of the shell 10 from the air inlet 11, the air will flow in the first air duct and the second air duct at the same time due to the action of the fan 20, and will take away the heat of the heating component 30 and be discharged from the shell through the air outlet 12. In another embodiment, the first air duct and the second air duct can be connected to an air inlet 11 respectively, and after the air enters one of the air inlets 11 due to the action of the fan, the air will flow in the first air duct; and after the air enters the interior of the shell 10 from the other air inlet 11, the air will flow in the second air duct. In this way, the first and second air ducts with different volumes can be designed according to the size of the heat generated by the heating component 30, for example, at the end close to the fan 20, the gas flow rate is constant, so as to achieve different gas flow rates in the first and second air ducts.

[0065] In this configuration, both sides of the driving circuit board 32 are spaced apart from other structures, and airflow can flow through both sides of the driving circuit board 32 , so that the air can better absorb the heat of the driving circuit board 32 .

[0066] In some embodiments, both side surfaces of the driving circuit board 32 are attached by heat conductive members 50, and the driving circuit board 32 is located between two air inlets 11. In this way, after air enters from the air inlets 11, the airflow can completely cover the interior of the shell 10, and the airflow can directly blow the heat conductive members 50 on both sides of the driving circuit board 32, thereby further improving the heat dissipation efficiency.

[0067] Further, see Figure 5 In one embodiment, a avoidance opening 311 is provided on the main control circuit board 31 , and a portion of the fan 20 is located in the avoidance opening 311 .

[0068] It should be noted that, in conjunction with Figure 5The fan 20 suitable for installing the avoidance opening 311 on the main control circuit board 31 is an axial flow fan, so that the axial flow fan can drive the air from one end of the main control circuit board 31 to the other end, that is, the air flow direction is along the axial direction of the shell 10, so as to achieve a better heat dissipation effect of the fan 20; it can be understood that the fan 20 can also be a turbo fan. Since the turbo fan changes the air flow direction, the air outlet 12 needs to be changed to be set on the side wall of the second end of the shell 10 to facilitate the turbo fan to blow out the hot air.

[0069] In this way, by setting the avoidance opening 311 on the main control circuit board 31, the fan 20 can be installed using the space provided by the avoidance opening 311, which can save the internal space of the shell 10, thereby reducing the volume of the heat dissipation handle 100.

[0070] In some embodiments, in order to further save the internal space of the shell 10, a clearance opening can also be set on the driving circuit board 32 according to the position of the clearance opening 311, so that the fan 20 can be installed in a larger space, and the heat dissipation handle 100 can be made smaller.

[0071] The utility model also proposes a therapeutic device, which includes a heat dissipation handle 100. The specific structure of the heat dissipation handle 100 refers to the above embodiment. Since the therapeutic device adopts all the technical solutions of all the above embodiments, it has at least all the beneficial effects brought by the technical solutions of the above embodiments, which will not be described one by one here.

[0072] The above description is only a preferred embodiment of the present invention, and does not limit the patent scope of the present invention. All equivalent structural changes made by using the contents of the present invention specification and drawings under the inventive concept of the present invention, or directly / indirectly applied in other related technical fields are included in the patent protection scope of the present invention.
