[0033] The terms "first", "second", "third", "fourth" and the like in the description and claims of the present application and above-mentioned drawings are used to distinguish similar objects, and do not necessarily have to be used to describe a particular order or sequence. It should be understood that the data used in this way can be exchanged under appropriate circumstances, so that the embodiments described herein can be implemented in an order other than that illustrated or described herein. In addition, the terms "include" and "have" and any variations thereof are intended to cover non-exclusive inclusion, for example, a process, method, system, product or device including a series of steps or units does not have to be limited to those steps or units clearly listed, but can include other steps or units not clearly listed or inherent to these processes, methods, products or devices.

[0034] Please refer to Figure 1 For one embodiment of the treatment handpiece in the embodiments of the present application, the treatment handpiece comprises a treatment head 1 and a handle 2, the treatment head 1 is used for being attached to the skin of the treatment area for treatment, the treatment head 1 is located at one end of the handle 2, and the handle 2 is detachably connected with the treatment head 1, so as to facilitate the disassembly and replacement of the treatment head 1.

[0035] Please refer to Figure 1 and Figure 2The treatment head 1 comprises a transducer module 11 and a housing 13, the housing 13 is provided with a receiving cavity 131 for accommodating a sound-conducting medium and a connecting port 132, the receiving cavity 131 is in communication with the connecting port 132, the transducer module 11 is used to generate ultrasonic waves, the transducer module 11 is arranged in the receiving cavity 131, and the connecting port 132 can be opened to facilitate the handle to extend into the receiving cavity 131 for heat dissipation. It can be understood that when performing a treatment work, the heat generated by the operation of the transducer module 11 is conducted into the sound-conducting medium and then absorbed by the sound-conducting medium. Through continuous use, the heat generated by the transducer module 11 gradually accumulates in the receiving cavity 131, so it is necessary to export the heat generated by the transducer module 11 and the heat in the sound-conducting medium to achieve heat dissipation. Since the connecting port 132 can be opened, the heat in the receiving cavity 131 can be diffused and conducted through the connecting port 132. At the same time, the communication between the receiving cavity 131 and the connecting port 132 enables the handle 2 of the external device to extend into the receiving cavity 131, realizes the direct contact between the handle 2 and the sound-conducting medium for heat transfer and heat dissipation, solves the problem of heat accumulation in the receiving cavity 131, can realize the effective heat dissipation of the treatment head 1, improves the heat dissipation efficiency of the treatment head 1, ensures that the temperature of the treatment head 1 will not be too high, thereby improving the use safety of the treatment head 1, and ensuring that the transducer module 11 in the treatment head 1 can work normally, thereby achieving the treatment effect.

[0036] Please refer to Figure 2 The treatment head 1 further comprises a first cover 12, a cover shell 14 and a second cover 15. The first cover 12 is fixed to the end of the housing 13 and forms a receiving cavity 131 with the housing 13. In this embodiment, the first cover 12 is fixedly connected to the housing 13 by bolts. The receiving cavity 131 is used to accommodate a sound-conducting medium, which is in a liquid state. The transducer module 11 is fixedly arranged in the first cover 12, and the transducer module 11 and the first cover 12 have a space for the handle 2 to extend into.

[0037] The end of the housing 13 away from the first cover 12 is provided with a treatment window 133, and the treatment window 133 is provided with a sound-transmitting film 134. The sound-transmitting film 134 can effectively isolate the external environment, prevent moisture, dust and other pollutants from entering the receiving cavity 131, thereby prolonging the service life of the equipment and ensuring its normal operation. In addition, the material of the sound-transmitting film 134 has good acoustic properties, which can make the ultrasonic waves penetrate efficiently without significant attenuation or reflection, ensuring that more energy is smoothly transmitted to the target tissue site. The central axis of the transducer module 11 coincides with the central axis of the treatment window 133, which means that the energy transmission path from the transmitting end to the receiving end is the most direct and shortest, which helps to reduce energy loss and improve efficiency, ensures that all emitted energy is effectively utilized within the expected range, and avoids unnecessary radiation to surrounding tissues as much as possible, thereby ensuring the safety and comfort of the user.

[0038] Further, in order to facilitate the handle 2 to extend into the accommodation cavity 131, the first cover 12 is provided with a connecting portion 121, which is hollow annular in this embodiment, and the connecting opening 132 is configured as an opening of the connecting portion 121, through which the handle can extend into the accommodation cavity 131.

[0039] When the treatment head 1 is not installed on the handle 2, in order to ensure the sealing of the accommodation cavity 131, the treatment head 1 further comprises a sealing cover 18, which is threadedly connected with the connecting portion 121 and covers the connecting opening 132 to prevent the sound guide medium in the accommodation cavity 131 from leaking. In this embodiment, the outer ring of the connecting portion 121 is externally threaded, and the inside of the sealing cover 18 is internally threaded, so that the sealing cover 18 and the connecting portion 121 are threadedly connected with each other. The sealing cover 18 and the sound permeable film 132 respectively seal the two ends of the shell 13, so that the accommodation cavity 131 is configured as a sealed cavity.

[0040] It can be understood that when the treatment head 1 needs to be installed on the handle 2, the thread connection between the sealing cover 18 and the connecting portion 121 is first released, so that the sealing cover 18 is separated from the connecting portion 121 to expose the connecting opening 132, and then the handle 2 is operated so that one end of the handle 2 extends through the connecting opening 132 and into the accommodation cavity 131.

[0041] When the treatment head 1 is installed on the handle 2, in order to ensure the sealing effect between the accommodation cavity 131, the treatment head further comprises a sealing member 17, which is preferably a sealing ring. In some embodiments, the sealing member 17 is arranged on the inner wall of the connecting portion 121, and a buffer member is arranged in the accommodation cavity 131 for pressure relief, and the handle 2 presses the sealing member 17 to seal the gap between the connecting opening 132 and the handle 2. Specifically, the inner wall of the connecting portion 121 is provided with a mounting groove for mounting the sealing member 17, and the sealing member 17 is arranged in the mounting groove to seal the gap between the inner wall of the connecting opening 132 and the handle 2. It can be understood that when the handle 2 extends through the connecting portion 121 and into the accommodation cavity 131, in order to ensure the sealing effect, the outer wall of the handle 2 contacts and presses the inner ring of the sealing member 17 to deform, and as the handle 2 extends, the air pressure in the treatment head 1 increases, and the buffer member is used for pressure relief to balance the air pressure in the accommodation cavity 131. This structure is suitable for the case where the structural size of the handle 2 extending into the accommodation cavity 131 is close to the size of the connecting opening 132, which facilitates the stable installation of the handle 2 and ensures the sealing effect of the accommodation cavity 131. In the working state of the transducer module 11, the sound guide medium expands due to the absorption of heat generated by the transducer module 11, thereby compressing the buffer member; in the non-working state of the transducer module 11, the temperature of the sound guide medium returns, the buffer member is no longer pressed, and gradually returns to the original state. The buffer member can achieve the effect of "contraction under pressure and recovery without pressure", thereby prolonging the service life of the treatment head 1.

[0042] In some other embodiments, the sealing member 17 is arranged at the end of the connecting portion 121, and the sealing member 17 is used to abut against the handle 2 and the connecting portion 121 to seal the connecting port 132. It can be understood that when the handle 2 penetrates the connecting portion 121 to extend into the receiving cavity 131, the gap between the handle 2 and the connecting portion 121 can realize the air pressure exchange between the receiving cavity 131 and the outside, which facilitates the smooth extension of the handle 2. In order to ensure the sealing effect, the sealing member 17 is arranged at the end of the connecting portion 121, so that the handle 2 cooperates with the connecting portion 121 to abut against the sealing member 17 during the extension process. The sealing member 17 is extruded by the handle 2 and the connecting portion 121, so as to realize the sealing of the receiving cavity 131 in the treatment head 1.

[0043] Please continue to refer to Figure 1 and Figure 2 The cover shell 14 is fixed to one side of the second cover body 15 and cooperates with the second cover body 15 to form a containing cavity 19. In the embodiment, the second cover body 15 is fixedly connected with the cover shell 14 by bolts. Further, the second cover body 15 is provided with an avoiding hole 151, and the connecting portion 121 penetrates the avoiding hole 151 and is located outside the containing cavity 19, which facilitates the extension of the handle 2 into the receiving cavity 131. The first cover body 12 and the shell 13 are located in the containing cavity 19, and the cover shell 14 and the second cover body 15 protect the first cover body 12 and the shell 13.

[0044] Please refer to Figure 1 and Figure 3 The handle 2 comprises a shell 22, an end cover 23 and a heat dissipation member 25. The end cover 23 is fixed to the end of the shell 22 and cooperates with the shell 22 to form a mounting cavity 24. The shell 22 is fixedly connected with the end cover 23 by bolts. The end cover 23 is provided with a mounting hole 231, and the heat dissipation member 25 penetrates the mounting hole 231 and is partially arranged in the mounting cavity 24. The other end of the heat dissipation member 25 extends into the receiving cavity 131 through the connecting port 132 and contacts with the sound guide medium. The heat generated by the transducer module 11 is transmitted to the heat dissipation member 25 for heat dissipation through the sound guide medium. It can be understood that the heat generated by the transducer module 11 gradually accumulates in the receiving cavity 131. By extending one end of the heat dissipation member 25 into the sound guide medium in the receiving cavity 131, the heat in the sound guide medium is subsequently guided out and dissipated through the heat dissipation member 25.

[0045] Specifically, the heat dissipation member 25 includes a heat conduction part 251 and a heat dissipation part 252. The heat dissipation part 252 is arranged in the mounting cavity 24 for heat dissipation. The heat conduction part 251 is at least partially located outside the mounting cavity 24 and extends into the receiving cavity 131 to conduct heat in the sound guide medium to the heat dissipation part 252 for heat dissipation. The heat conduction part 251 is provided with a first end and a second end. The first end is located in the mounting cavity 24, and the second end is located outside the mounting cavity 24. The first end penetrates the mounting hole 231 and abuts against the connecting part 121. The second end penetrates the connecting opening 132 and extends into the receiving cavity 131. In this embodiment, the second end is in a columnar structure. The central axis of the transducer module 11 coincides with the central axis of the second end, so that the second end is located at the middle position of the sound guide medium. All available surface areas of the second end are fully utilized to more efficiently transfer heat in the heat conduction medium. Compared with the edge position arrangement, this mode can provide better heat dissipation effect in a smaller space. At the same time, heat can rapidly spread from the second end to the surrounding, avoiding the situation of single-side heating, which helps to achieve a more balanced temperature field in the entire sound guide medium and reduces the problem of local overheating points.

[0046] The heat dissipation part 252 is arranged along the length direction of the handle 2, so that the volume of the heat dissipation part 252 can be arranged as large as possible in the mounting cavity 24. The heat dissipation part 252 is provided with a plurality of heat dissipation fins. The presence of the heat dissipation fins greatly increases the heat dissipation surface of the heat dissipation part 252 in a unit volume. More heat dissipation fins mean a larger total surface area. The gaps between the fins can guide airflow to pass through, forming a natural convection effect, which helps to carry away more heat and can more effectively dissipate the heat generated inside, improving the heat transfer efficiency.

[0047] In order to realize the detachable connection between the treatment head 1 and the handle 2, the end face of the second cover body 15 towards the handle 2 is provided with a buckle 152. The end face of the end cover 23 towards the treatment head 1 is provided with a clamping groove 232 for clamping the buckle 152. The treatment head 1 and the handle 2 are clamped and fastened by the clamping of the buckle 152 and the clamping groove 232. When it is necessary to disassemble the treatment head 1 and the handle 2, the buckle 152 is pushed out of the clamping groove 232 by operating the buckle 152, so as to release the clamping of the buckle 152 and the clamping groove 232, thereby disassembling the treatment head 1 from the handle 2.

[0048] The above-described embodiments are only used to illustrate the technical solutions of the present application, but not limit the present application. Although the present application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that they can still make modifications to the technical solutions recorded in the foregoing embodiments, or make equivalent replacements to some technical features.
