[0027] Please refer to Figures 1 to 3 Figures 1 to 3 , the present utility model provides a beauty treatment instrument handle 100, comprising: a housing 10; a heating element 20; and a heat sink 30. The heat sink 30 is disposed within the housing 10. The heat sink 30 at least partially abuts and cooperates with the inner wall of the housing 10 and divides the housing 10 into a first installation space 11 and a second installation space 12. The heating element 20 is located within the first installation space 11. The heat sink 30 is in contact with the heating element 20. Wherein, a heat dissipation air duct 31 is formed on the heat sink 30. The heat dissipation air duct 31 is located within the second installation space 12. An air inlet 13 and an air outlet 14 are formed on the housing 10. The openings at both ends of the heat dissipation air duct 31 are respectively communicated with the air inlet 13 and the air outlet 14.

[0028] Specifically, the beauty treatment instrument handle 100 includes a housing 10, a heating element 20 and a heat sink 30. The housing 10 is used to protect internal components. Both the heating element 20 and the heat sink 30 are disposed within the housing 10. The heating element 20 generates heat during use. The heating element 20 may be a radio frequency generator, a laser or an ultrasonic generator, etc. The heat sink 30 is used to dissipate heat from the heating element 20 to maintain its performance and extend its service life.

[0029] The heat sink 30 divides the internal space of the housing 10 into a non-communicating first installation space 11 and a second installation space 12. The first installation space 11 is used to install the heating element 20. The heating element 20 is in contact with the heat sink 30. The heating element 20 transfers heat to the heat sink 30. Heat dissipation of the heat sink 30 is performed within the second installation space 12. The specific method for dissipating heat from the heat sink 30 is to form air convection by opening an air inlet 13 and an air outlet 14 on the wall surface of the housing 10 located within the second installation space 12 to dissipate heat from the heat sink 30. At the same time, a heat dissipation air duct 31 is formed on the heat sink 30 located within the second installation space 12. The heat dissipation air duct 31 is communicated with the air inlet 13 and the air outlet 14 to form air circulation, increasing the heat dissipation area of the heat sink 30 and better dissipating heat from the heat sink 30.

[0030] Therefore, the heat of the heating element 20 is transferred to the heat sink 30, and the heat sink 30 quickly dissipates the heat through the heat dissipation air duct 31 and the air inlet 13 and the air outlet 14. Since the first installation space 11 and the second installation space 12 are not communicated with each other, the heating element 20 is restricted within the closed first installation space 12 composed of the heat sink 30 and the housing 10, and external water vapor cannot enter the first installation space, so that the heating element 20 has a very good waterproof effect.

[0031] The specific shape of the heat dissipation member 30 can be set according to actual needs. It can be set as a heat dissipation block, or a heat dissipation plate. It can also keep one end in contact with the heating element 20 and the other end extending towards the second installation space. It only needs to be able to contact the heating element 20 and divide the housing 10 into the first installation space 11 and the second installation space 12. When there are multiple heating elements 20 inside the therapeutic apparatus, multiple contact ends of the heat dissipation member 30 can also be set to extend towards multiple heating elements 20 and contact the multiple heating elements 20 respectively to dissipate heat from the multiple heating elements 20.

[0032] In the technical solution of the present utility model, by providing the heat dissipation member 30 inside the housing 10, the heat dissipation member 30 divides the housing 10 into the first installation space 11 and the second installation space 12. The heating element 20 is installed in the first installation space 11 and separated from the heat dissipation air duct 31 located in the second installation space 12. By setting the heat dissipation member 30 in contact with the heating element 20, the heat of the heating element 20 can be transferred to the heat dissipation member 30, and the heat of the heat dissipation member 30 is dissipated through the heat dissipation air duct 31 in the second installation space 12 to complete the heat dissipation of the heating element 20. By directly providing the heat dissipation air duct 31 on the heat dissipation member 30 itself, the heat absorbed by the heat dissipation member 30 from the heating element 20 can be quickly conducted to the heat dissipation air duct 31 in the second installation space 12 for heat dissipation, achieving fast heat dissipation while meeting the waterproof requirements of the internal heating element 20.

[0033] In an embodiment of the present utility model, an installation position 32 is recessed inwardly on the outer wall of the heat dissipation member 30, and the heating element 20 is placed in the installation position 32 and contacts the wall surface of the installation position 32.

[0034] Specifically, the contact manner between the heat dissipation member 30 and the heating element 20 can be set according to actual needs. It can only contact the end face of the heat dissipation member 30 with the end face of the heating element 20, or a stepped surface can be provided for the heating element 20 to abut and contact. As Figure 3 , an installation position 32 is recessed on the outer wall of the heat dissipation member 30 located in the first installation space 11 to accommodate the heating element 20. Multiple end faces of the heating element 20 contact multiple wall surfaces of the installation position 32, which can increase the contact area between the heating element 20 and the heat dissipation member 30, provide a larger heat exchange area. The increase in the contact area improves the rate of heat transfer, enhances the heat dissipation effect, and realizes fast heat dissipation.

[0035] In addition, a thermally conductive adhesive layer is provided between the heat sink 30 and the heating element 20. By providing the thermally conductive adhesive layer, located between the heat sink 30 and the heating element 20, it can be used as an adhesive to support and fix the heating element 20, ensuring that the heating element 20 maintains stable contact with the heat sink 30 during use. The thermally conductive adhesive layer has a high thermal conductivity, and by reducing thermal resistance, it can quickly and smoothly conduct the heat of the heating element 20 to the heat sink 30, helping the heating element 20 to dissipate heat.

[0036] In the embodiment of the present utility model, the openings at both ends of the heat dissipation duct 31 are respectively located on two adjacent wall surfaces of the heat dissipation element 30 , and the heat dissipation duct 31 is arranged in an arc-shaped channel.

[0037] In some embodiments, the heat dissipation duct 31 can be set to be linear, U-shaped, spiral, etc. The specific shape can be set according to actual conditions. Figure 2 The heat dissipation duct 31 is arranged in an arc shape, and the openings at both ends of the heat dissipation duct 31 are arranged at intervals along the adjacent walls of the heat dissipation duct 31. At the same time, the air inlet 13 and the air outlet 14 of the shell 10 are also arranged at intervals along the adjacent walls of the shell 10, corresponding to the openings at both ends of the heat dissipation duct 31.

[0038] The curved heat dissipation duct 31 can guide the air flow to be smoother, reduce the turbulence and eddy current of the air flow in the heat dissipation duct 31, thereby reducing the noise of the beauty therapy device handle 100 when in use. The curved heat dissipation duct 31 can also reduce resistance, make the air flow smoother, and improve the heat dissipation efficiency, so as to quickly dissipate the heat of the heating element 20.

[0039] In the embodiment of the present utility model, the end surface area of ​​the air inlet end 311 of the heat dissipation air duct 31 is larger than the end surface area of ​​the air outlet end 312 of the heat dissipation air duct 31 .

[0040] In detail, the air inlet end 311 of the heat dissipation air duct 31 has a larger area. The larger air inlet area can increase the air flow rate and improve the air flow speed. The faster air flow can more effectively take away the heat, thereby improving the heat dissipation efficiency and the heat dissipation effect.

[0041] In addition, if Figure 2 The end surface area of ​​the air inlet 13 on the shell 10 is also set to be larger than the end surface area of ​​the air outlet 14, so that the air inlet end 311 of the heat dissipation duct 31 can receive more air volume, and the flow channel formed by the heat dissipation duct 31 and the air inlet 13 and the air outlet 14 has a larger area at the flow channel inlet than the flow channel outlet, thereby better improving the heat dissipation efficiency and enhancing the heat dissipation performance.

[0042] In an embodiment of the present utility model, it further includes a cooling fan 40, and the cooling fan 40 is installed in the second installation space 12 and is located between the air inlet end 311 of the cooling air duct 31 and the air inlet 13.

[0043] Specifically, a cooling fan 40 is arranged in the second installation space 12. By rotating the cooling fan 40, air flow can be generated, increasing the air flow speed, enabling air to pass through the cooling air duct 31 faster, accelerating the heat exchange process, thereby improving the heat exchange efficiency, better dissipating heat from the heat dissipation component 30, improving the heat dissipation effect on the heating element 20, and enhancing the overall heat dissipation performance. Through effective heat dissipation, the heat dissipation effect of the beauty treatment instrument handle 100 can be improved, which helps to extend the service life of the beauty treatment instrument handle 100.

[0044] At the same time, the flow path formed by the cooling air duct 31 and the air inlet 13 and the air outlet 14, combined with the relatively large inlet area of the flow path, can reduce the resistance when air enters the flow path, making it easier for the cooling fan 40 to inhale more air, thereby improving the overall air flow efficiency and the heat dissipation effect. Due to the relatively large inlet area, the cooling fan 40 does not need to operate at a very high rotational speed to maintain the required air flow rate, which is beneficial to reducing the noise generated by the cooling fan 40 and enhancing the usage experience of the beauty treatment instrument handle 100.

[0045] In an embodiment of the present utility model, a support frame 15 is provided in the second installation space 12 of the housing 10, and the cooling fan 40 is installed on the support frame 15.

[0046] Specifically, as Figure 2 , the support frame 15 is arranged in the second installation space 12, which can provide stable support for the cooling fan 40, maintain the installation stability of the cooling fan 40 in the second installation space 12, better drive the air flow through the cooling air duct 31, and improve the heat dissipation efficiency.

[0047] In an embodiment of the present utility model, the support frame 15 includes a support sleeve 151 and a limiting plate 152. The support sleeve 151 is arranged on the inner end face of the housing 10 close to the air inlet 13 and is communicated with the air inlet 13. The limiting plate 152 extends along the inner side wall of the housing 10 towards the middle of the housing 10, and the limiting plate 152 is located on the side of the support sleeve 151 away from the air inlet 13; the cooling fan 40 includes a fan body 41 and an installation cylinder 42 connected to the outside of the fan body 41. One end of the support sleeve 151 is sleeved outside the installation cylinder 42, and a connection hole is formed in the limiting plate 152, and the limiting plate 152 is sleeved on the middle of the installation cylinder 42 through the connection hole.

[0048] Specifically, as Figure 2, the housing of the cooling fan 40 is set to a cylindrical shape, and the support frame 15 is also set to a sleeve shape, facilitating the sleeving of the support sleeve 151 on the installation cylinder 42 for easy installation and cooperation between the two. The support sleeve 151 is provided on the inner end surface of the air inlet 13 of the housing 10, and the support sleeve 151 can be integrally formed with the housing 10. The support sleeve 151 communicates with the air inlet 13, and can better guide the air flow from the air inlet 13 to the installation cylinder 42. The fan body 41 rotates to further guide the air flow to the heat dissipation duct 31, making the air flow smoother, improving the efficiency of air flow, and increasing the flow rate. The limiting plate 152 can also be integrally formed with the housing 10. By providing the limiting plate 152, the limiting plate 152 can be further fixed outside the installation cylinder 42 of the cooling fan 40 to keep the cooling fan 40 stable during use.

[0049] In an embodiment of the present invention, a socket cylinder portion 33 is convexly provided on the end surface of the heat dissipation member 30 close to the support frame 15, and the socket cylinder portion 33 is sleeved on the other side outside the installation cylinder 42.

[0050] It should be noted that the heat dissipation member 30 is also connected to the installation cylinder 42 through the socket cylinder portion 33, thus forming an air inlet air flow guiding structure of the air inlet 13, the support sleeve 151, the installation cylinder 42, and the socket cylinder portion 33 arranged in sequence, facilitating the guiding of the air flow to the heat dissipation duct 31, enabling the air flow to flow in along the air inlet 13, with smoother air inlet, smoother air flow, better heat dissipation of the heating element 20, and improved heat dissipation effect. At the same time, the installation method of the cooling fan 40 and the heat dissipation member 30 makes the maintenance more convenient. Only the housing 10 and the corresponding components need to be disassembled. After maintenance, they can be directly assembled, with simple maintenance and low maintenance cost.

[0051] In an embodiment of the present invention, a sealing member (not shown in the figure) is provided in a ring between the support sleeve 151 and the installation cylinder 42; and / or, a sealing member is provided in a ring between the installation cylinder 42 and the socket cylinder portion 33; and / or, a sealing member is provided in a ring between the wall surface of the outer periphery of the air outlet end 312 of the heat dissipation duct 31 and the inner wall of the housing 10.

[0052] Specifically, the seal can be an O-ring, a gasket, etc., and the specific structure can be selected according to actual needs. By providing seals between the support sleeve 151 and the mounting cylinder 42, between the mounting cylinder 42 and the socket cylinder portion 33, and between the outer wall surface of the air outlet end 312 of the heat dissipation air duct 31 and the inner wall of the housing 10, the sealing performance can be enhanced, a waterproof design can be formed, the first installation space 11 and the second installation space 12 can be better partitioned, and moisture can be prevented from entering the second installation space 12 to affect the heating element 20. Seals can also be provided only between the support sleeve 151 and the mounting cylinder 42, or only between the mounting cylinder 42 and the socket cylinder portion 33, or only between the outer wall surface of the air outlet end 312 of the heat dissipation air duct 31 and the inner wall of the housing 10 to strengthen the sealing performance and prevent moisture from entering the second installation space 12.

[0053] In an embodiment of the present invention, the beauty treatment instrument handle 100 is one of an ultrasonic treatment instrument handle, a radio frequency treatment instrument handle, and a laser treatment instrument handle.

[0054] Specifically, the beauty treatment instrument can be an ultrasonic treatment instrument, a radio frequency treatment instrument, a laser treatment instrument, etc. The main heating element 20 inside the ultrasonic treatment instrument handle is an ultrasonic generator, which generates heat through ultrasonic vibration; the main heating element 20 inside the radio frequency treatment instrument handle is a radio frequency generator, which heats the skin through radio frequency energy and also generates heat; the main heating element 20 inside the laser treatment instrument handle is a laser, which uses a beam of a specific wavelength to treat the skin, and the laser energy is converted into heat in the skin, thereby generating heat.

[0055] The specific structure of the beauty treatment instrument handle 100 refers to the above embodiment. Since the ultrasonic treatment instrument handle, the radio frequency treatment instrument handle, or the laser treatment instrument handle adopts all the technical solutions of the above all embodiments, the heating element 20 can be better dissipated of heat, and the waterproof effect can be maintained, improving the user experience and prolonging the service life of the treatment instrument. The ultrasonic treatment instrument handle, the radio frequency treatment instrument handle, or the laser treatment instrument handle at least has all the beneficial effects brought by the technical solutions of the above embodiment, which will not be elaborated one by one here.

[0056] The above are only the preferred embodiments of the present invention, and do not limit the patent scope of the present invention accordingly.
