[0002] Most ultrasound therapy devices use a fixed focal length design and lack focal length adjustment. A small number of devices have adjustable focal length, but these typically have a fixed point structure, with the transducer assembly adjusting the focal length by reaching a starting point, a fixed intermediate point, or an endpoint. However, this method has drawbacks: the transducer assembly cannot be adjusted to any desired focal length; it can only achieve fixed focal length adjustment based on the point structure, resulting in limited treatment effectiveness. Summary of the Invention

[0005] In one embodiment, the spring pin includes a guide sleeve and a movable body. The movable body is movably disposed within the guide sleeve, and the guide sleeve is fixedly disposed within the housing. The transducer assembly drives the movable body to move, and the movable body contacts the detection assembly.

[0006] In one embodiment, the detection assembly includes a detection board and a main control board, which are spaced apart within the housing. The detection board is positioned close to the transducer assembly, and the main control board is located on the side of the detection board opposite to the transducer assembly. The detection board is electrically connected to the main control board, the guide sleeve is fixedly connected to the detection board, and the moving body passes through the detection board.

[0007] In one embodiment, the detection assembly further includes a soft protective sleeve, one end of which is open and fixed to the detection plate, and the other end of which extends toward the sound-transmitting port, with the spring pin partially extending into the soft protective sleeve.

[0008] In one embodiment, the detection component further includes a connecting plate disposed within the housing, the connecting plate being electrically connected to the main control board and the connecting plate being electrically connected to the external drive mechanism.

[0009] In one embodiment, the treatment head further includes a transmission assembly disposed within the housing, the output shaft of the external drive mechanism being connected to one end of the transmission assembly, and the transducer assembly being threadedly connected to the other end of the transmission assembly.

[0010] In one embodiment, the treatment head further includes a support member fixedly connected to the housing, the support member having a connection hole; the transmission assembly includes an intermediate member and a bearing, the bearing being fixedly connected to the connection hole, one end of the intermediate member being connected to the output shaft of the external drive mechanism, the other end of the intermediate member extending into the bearing and fixedly connected to the bearing, the intermediate member having a threaded hole, the transducer assembly partially extending into the threaded hole and threadedly connected to the intermediate member; the detection assembly is connected to the outside of the support member, and the spring pin is movably disposed on the detection assembly.

[0013] In one embodiment, the treatment head further includes a sealing assembly, which includes a sealing ring and a sealing plate. The sealing ring is sleeved on the outside of the support, and the outer wall of the sealing ring abuts against the wall of the connecting hole. The sealing plate is sleeved on the outside of the support and fixedly connected to the peripheral end face of the connecting hole.

[0014] The present invention also provides a treatment device, including a handle and a treatment head as described above.

[0015] Compared with the prior art, the treatment head and treatment device provided by the present invention have the following beneficial effects:

[0016] The present invention uses an external drive mechanism to move the transducer assembly. As the transducer assembly moves, it gradually approaches and contacts the spring pin, causing the spring pin to move until it contacts the detection assembly, generating a short-circuit signal. The detection assembly is electrically connected to the external drive mechanism, and the short-circuit signal is transmitted to the external drive mechanism. Upon receiving the short-circuit signal, the external drive mechanism shuts down, at which point the transducer assembly stops moving. The position where the movement stops is simultaneously identified as the starting point. Therefore, the focal length depth adjustment is based on this starting point as a reference point, thereby achieving the purpose of detecting the starting point. Thus, the external drive mechanism can output various focal length depths to meet the user's needs based on this starting point, in order to achieve the corresponding therapeutic effect.

Obviously, the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present invention.

Therefore, a feature defined with "first" or "second" may explicitly or implicitly include at least one of that feature. Additionally, the technical solutions of the various embodiments can be combined with each other, but only on the basis of being achievable by those skilled in the art. When the combination of technical solutions is contradictory or impossible to implement, such a combination of technical solutions should be considered non-existent and not within the scope of protection claimed by this invention.

[0028] Please refer to Figures 1 to 4 This invention proposes a treatment head 100, comprising: a housing 10; a transducer assembly 20 movably disposed within the housing 10; an external drive mechanism 30 mounted on the housing 10, the output end of the external drive mechanism 30 being connected to the transducer assembly 20 to drive the transducer assembly 20 to move; and an identification component 40, comprising a detection component 41 and a spring pin 42, the detection component 41 being disposed within the housing 10, the spring pin 42 being movably disposed within the housing 10, and the detection component 41 being electrically connected to the external drive mechanism 30; wherein, the external drive mechanism 30 drives the transducer assembly 20 to move, the transducer assembly 20 pressing against the spring pin 42 to move the spring pin 42, and the spring pin 42 contacting the detection component 41 to trigger a short-circuit signal.

[0029] Specifically, the treatment head 100 includes a housing 10, a transducer assembly 20, an external drive mechanism 30, and an identification component 40. The housing 10 is used to protect and install internal components, the transducer assembly 20 is used to convert electrical energy into mechanical energy, the external drive mechanism 30 is used to drive the transducer assembly 20 to move, and the identification component 40 is used to detect the starting point of focus adjustment.

[0030] The transducer assembly 20 is movably installed inside the housing 10. Its specific installation method can be set to move along the sliding track or be connected to the telescopic arm. The specific installation method can be set according to actual needs.

[0031] The specific structure of the external drive mechanism 30 can be selected according to actual needs; it can be driven by a motor 31 or by pneumatic drive.

[0032] Reference Figure 3 The specific method for detecting the starting point of focus adjustment is as follows: the transducer assembly 20 can move vertically, the spring pin 42 is movable within the housing 10, the detection assembly 41 is electrically connected to the external drive mechanism 30, and the external drive mechanism 30 drives the transducer assembly 20 to move. When the transducer assembly 20 moves, it will gradually approach and contact the spring pin 42, and drive the spring pin 42 to move until the spring pin 42 contacts the detection assembly 41 and triggers a short circuit signal. The external drive mechanism 30 closes after receiving the short circuit signal. At this time, the transducer assembly 20 stops moving, and this position where it stops moving is simultaneously identified by the external drive mechanism 30 as the starting point. All focus depth adjustments are based on this starting point as the reference point, thereby achieving the purpose of starting point detection.

[0033] There are two specific methods for adjusting focal length depth. The first method involves identifying the starting point each time a desired focal length depth needs to be adjusted, and then adjusting the focal length of the transducer assembly 20 based on that starting point position. The second method involves adjusting the focal length depth after the starting point is identified. The next focal length depth adjustment can then be performed based on the position of the previous adjustment, eliminating the need to identify the starting point and adjust based on its position each time, making the adjustment more convenient.

[0034] The detection component 41 can be configured with two metal contacts, one of which is fixed and the other is connected to the spring pin 42. When the spring pin 42 moves and contacts the fixed metal contact, a closed circuit is formed between the two contacts, thereby triggering a short-circuit signal. Alternatively, it can be configured with a flexible metal sheet or spring. When the spring pin 42 moves and contacts the spring contact, the elasticity of the spring ensures good contact, thereby triggering a short-circuit signal. It can also be configured as a circuit board. When the spring pin 42 moves and contacts the contacts on the circuit board, a short-circuit signal can be triggered. The specific structure of the detection component 41 can be configured according to actual needs.

[0035] By setting the identification component 40, the external drive mechanism 30 receives a short-circuit signal and identifies the starting position. This design can output treatment depths with multiple focal lengths. The specific depth can be adjusted according to actual needs and is not prone to errors. It can provide users with a variety of treatment options with different focal lengths, such as 2.0mm, 3.0mm, and 4.5mm. Users can choose any one or more focal lengths for treatment according to their treatment needs, resulting in good treatment effects and excellent production results.

[0036] The technical solution of this invention uses an external drive mechanism 30 to drive the transducer assembly 20 to move. When the transducer assembly 20 moves, it gradually approaches and contacts the spring needle 42, and drives the spring needle 42 to move until the spring needle 42 contacts the detection assembly 41 and generates a short circuit signal. The detection assembly 41 is electrically connected to the external drive mechanism 30, and the short circuit signal is transmitted to the external drive mechanism 30. After receiving the short circuit signal, the external drive mechanism 30 shuts down. At this time, the transducer assembly 20 stops moving, and the position where it stops moving is simultaneously identified as the starting point. Therefore, the focal length depth adjustment is based on this starting point as a reference point, thereby achieving the purpose of detecting the starting point. Thus, the external drive mechanism 30 can output multiple focal length depths to meet the user's needs based on this starting point, so as to achieve the corresponding therapeutic effect.

[0037] In an embodiment of the present invention, the spring pin 42 includes a guide sleeve 421 and a movable body 422. The movable body 422 is movably disposed within the guide sleeve 421, and the guide sleeve 421 is fixedly disposed within the housing 10. The transducer assembly 20 drives the movable body 422 to move, and the movable body 422 contacts the detection assembly 41.

[0038] In detail, the guide sleeve 421 of the spring pin 42 is fixedly connected to the housing 10, and the movable body 422 is movable along the guide sleeve 421. Therefore, when the transducer assembly 20 moves, it can drive the movable body 422 to move within the guide sleeve 421, thereby causing the movable body 422 to contact the detection assembly 41 to trigger a short circuit signal.

[0039] This configuration provides good mechanical stability, ensuring the relatively stable position of the spring pin 42. Driven by the transducer assembly 20, precise control of the position of the moving body 422 can be achieved. The moving body 422 can accurately contact the detection assembly 41, thereby ensuring reliable triggering of the short-circuit signal. Furthermore, the moving body 422 is located within the guide sleeve 421, reducing wear. The guide sleeve 421 can guide and protect the moving body 422.

[0040] In an embodiment of the present invention, the detection component 41 includes a detection plate 411 and a main control board 412. The detection plate 411 and the main control board 412 are spaced apart within the housing 10. The detection plate 411 is located close to the transducer assembly 20, and the main control board 412 is located on the side of the detection plate 411 opposite to the transducer assembly 20. The detection plate 411 and the main control board 412 are electrically connected. The guide sleeve 421 is fixedly connected to the detection plate 411, and the moving body 422 passes through the detection plate 411.

[0041] It is worth noting that, such as Figure 4 The detection component 41 is configured as a detection board 411 and a main control board 412. The detection board 411 and the main control board 412 are electrically connected. By connecting the moving body 422 to the detection board 411, the transducer component 20 moves and drives the moving body 422 to move. The moving body 422 can contact the main control board 412 to form a closed circuit, thereby triggering a short circuit signal.

[0042] By setting the detection board 411 and the main control board 412 at intervals, short circuits or other electrical interference that may be caused by direct contact between the two can be avoided; at the same time, the guide sleeve 421 is fixedly connected to the detection board 411 to ensure that the moving body 422 moves accurately along the predetermined path during the movement, which improves the stability of the movement and makes the triggering of the short circuit signal more reliable.

[0043] In an embodiment of the present invention, the detection component 41 further includes a soft protective sleeve 43, one end of which is open and fixed to the detection plate 411. The other end of the soft protective sleeve 43 extends toward the sound-transmitting port 12, and the spring pin 42 extends partially into the soft protective sleeve 43.

[0044] In detail, such as Figure 3 The soft protective sleeve 43 is fitted over the outside of the spring pin 42 and is located at the end of the spring pin 42 that contacts and abuts against the transducer assembly 20. The soft protective sleeve 43 can be made of different materials, such as rubber or silicone.

[0045] By providing a soft protective sleeve 43, the spring pin component 42 can be protected from external environmental influences such as dust and impurities. The soft protective sleeve 43 also provides cushioning, reducing shock when the spring pin component 42 is subjected to external impacts or vibrations, thus protecting internal components from damage. Furthermore, the soft protective sleeve 43 reduces direct contact between the spring pin component 42 and the transducer assembly 20, thereby reducing wear. In applications requiring repeated movement, such as focus adjustment, the soft protective sleeve 43 can extend the service life of the spring pin component 42.

[0046] Furthermore, when the transducer assembly 20 is removed, the spring pin 42 can be reset by the internal spring. The spring pin 42 is protected by a soft protective sleeve 43, which provides a good sealing effect.

[0047] In an embodiment of the present invention, the detection component 41 further includes a connecting plate 413, which is disposed inside the housing 10. The connecting plate 413 is electrically connected to the main control board 412 and to the external drive mechanism 30.

[0048] It is worth noting that by setting the connection board 413 to be electrically connected to both the main control board 412 and the external drive mechanism 30, the connection board 413 can transmit the short-circuit signal from the main control board 412 to the external drive mechanism 30, which helps to achieve more efficient and reliable signal interaction. As an intermediate component 321, the connection board 413 can more easily integrate various components together, making the design of the entire device more compact and reasonable.

[0049] Meanwhile, signal processing and protection circuits can also be integrated on the connection board 413 to ensure the accuracy and integrity of the signal and improve the reliability and stability of the equipment.

[0050] In one embodiment, a control board is also provided in the handle. The control board in the handle is electrically connected to the external drive mechanism 30 and the connecting plate 413 in the treatment head. The main signal processing is that the control board at the handle end controls the external drive mechanism 30 to stop according to the short-circuit signal transmitted from the treatment head end.

[0051] In another embodiment, such as Figure 2 The identification component 40 includes a soft protective sleeve 43, a spring needle 42, a detection plate 411, a connecting wire 414, a main control board 412, and a connecting plate 413. The assembly relationship is as follows: the spring needle 42, the detection plate 411, and the connecting wire 414 are welded together to form a component. The soft protective sleeve 43 is fitted into the corresponding mounting hole of the housing 10, and then the component is installed and tightened with screws. The other end of the connecting wire 414 is then welded to the main control board 412 of the treatment head to make it conductive with the main control board 412.

[0052] In use, the transducer assembly 20 squeezes the soft protective sleeve 43, causing the spring needle 42 to push upward. When the spring needle 42 contacts the main control board 412, the spring needle 42 generates a closed-loop short circuit signal with the main control board 412 through the connecting line 414 and the contact point of the spring needle 42. The short circuit signal is transmitted back to the external drive mechanism 30 through the treatment head main control board 412 and the treatment head connecting plate 413. After receiving the short circuit signal, the external drive mechanism 30 shuts down, and the transducer assembly 20 stops moving.

[0053] In an embodiment of the present invention, the treatment head 100 further includes a transmission assembly 32, which is disposed inside the housing 10. The output shaft of the motor 31 is connected to one end of the transmission assembly 32, and the transducer assembly 20 is threadedly connected to the other end of the transmission assembly 32.

[0054] Specifically, the external drive mechanism 30 is configured as a combination of a motor 31 and a transmission component 32. The motor 31 provides stable power output, while the transmission component 32 converts the power into precise displacement. By threading the transducer assembly 20 to the transmission component 32, precise control of the transducer assembly 20 can be achieved, ensuring that the transducer assembly 20 can move accurately as needed. In addition, the threaded connection facilitates assembly and disassembly, making maintenance and component replacement convenient.

[0055] In an embodiment of the present invention, the treatment head 100 further includes a support member 50, which is fixedly connected to the housing 10 and has a connection hole 51; the transmission assembly 32 includes an intermediate member 321 and a bearing 322, the bearing 322 is fixedly connected to the connection hole 51, one end of the intermediate member 321 is connected to the output shaft of the motor 31, and the other end of the intermediate member 321 extends into the bearing 322 and is fixedly connected to the bearing 322; the intermediate member 321 has a threaded hole (not shown in the figure), and the transducer assembly 20 extends partially into the threaded hole and is threadedly connected to the intermediate member 321; the detection assembly 41 is connected to the outside of the support member 50, and the spring needle member 42 is movably disposed on the detection assembly 41.

[0056] In detail, the support member 50 is fixedly connected to the housing 10 and has a connection hole 51 for fixing the bearing 322. By setting the bearing 322, wear can be reduced and the service life of the transmission component 32 can be extended.

[0057] In one embodiment, the intermediate component 321 is configured as a connector and a connecting shaft. The connector is used to dock with the motor 31 and is fixedly connected to the connecting shaft. The connecting shaft extends into the bearing 322 and is fixedly connected to the bearing 322.

[0058] The intermediate component 321 extends into the bearing 322 and is fixedly connected to the bearing 322, which can ensure the connection stability of the intermediate component 321, so that the power of the motor 31 can be efficiently transmitted to the transducer assembly 20.

[0059] The transducer assembly 20 is threadedly connected to the intermediate part 321, which not only enables precise movement of the transducer assembly 20, but also facilitates installation and disassembly, improving the convenience of maintenance; through the threaded connection, the position of the transducer assembly 20 can be adjusted according to actual needs, so that the equipment can adapt to different treatment needs.

[0060] The detection component 41 is connected to the outside of the support 50, which ensures that the detection component 41 will not affect the movement of the transmission component 32.

[0061] The starting point detection function can identify the starting point position, thereby outputting a precise focal depth. This process is achieved by connecting the motor 31 to the transmission component 32 and the transducer component 20, and automatically adjusting the kinetic energy output of the motor 31 to the transducer component 20.

[0062] In an embodiment of the present invention, the transducer assembly 20 includes a bracket 21 and a transducer body 22. The transducer body 22 is connected to one end of the bracket 21, and the other end of the bracket 21 extends into the threaded hole and is threadedly connected to the intermediate part 321.

[0063] It is worth noting that the bracket 21 provides mechanical support, ensuring the stability of the transducer body 22 during operation. The threaded connection between the bracket 21 and the intermediate component 321 ensures a tight connection between the transducer assembly 20 and the transmission assembly 32, and also enables precise position adjustment of the transducer assembly 20, facilitating easy adjustment of the transducer assembly 20.

[0064] In an embodiment of the present invention, the bracket 21 is provided with two guide rods 23, and the support member 50 is provided with two guide cylinders 52 on the side facing the bracket 21, and the two guide rods 23 extend into the two guide cylinders 52 respectively.

[0065] Specifically, such as Figure 2 Two guide rods 23 are set up and connected to two guide cylinders 52. The movement of the guide rods 23 within the guide cylinders 52 can provide a precise guiding path for the transducer assembly 20. Through the guidance of the guide rods 23, it is ensured that the transducer assembly 20 will not deviate or tilt during movement.

[0066] Furthermore, the design of the guide rod 23 and guide cylinder 52 simplifies the installation of the transducer assembly 20. During installation, simply align the guide rod 23 with the guide cylinder 52 and insert it. In use, the transducer assembly 20 can be restricted from rotation to allow for height-based position adjustment and focus adjustment.

[0067] In an embodiment of the present invention, the treatment head 100 further includes a sealing component 60, which includes a sealing ring 61 and a sealing plate 62. The sealing ring 61 is sleeved on the outside of the support 21, and the outer wall of the sealing ring 61 abuts against the wall of the connecting hole 51. The sealing plate 62 is sleeved on the outside of the support 21 and fixedly connected to the peripheral end face of the connecting hole 51.

[0068] In detail, the sealing ring 61 effectively prevents dust, moisture, or other contaminants from entering the water tank 11 where the transducer assembly 20 is located. It also effectively prevents liquid from seeping into the interior, protecting components such as the motor 31 and transmission assembly 32 from damage. The dual protection of the sealing ring 61 and the sealing plate 62 ensures that the equipment maintains good performance and reliability even during long-term use.

[0069] The present invention also provides a treatment device (not shown), including a handle (not shown) and a treatment head as described above.

[0070] In one embodiment, the motor 31 is connected to the handle, and the treatment head is mounted on the handle. The connector of the motor 31 on the handle is connected to the connector on the treatment head. When the motor 31 is started, it transmits kinetic energy to the connector of the treatment head through the connector of the motor 31 and drives the transmission component 32 to rotate. The transmission component 32 and the support 21 of the transducer component 20 are connected by threads to drive the transducer body 22 to move. A water tank 11 is provided inside the housing 10. The transducer body 22 is fixed to the support 21 by applying glue. Two sealing rings 61 are fitted on the outside of the support 21. A sealing plate 62 is covered at the connection hole 51 and locked with screws. The intermediate component 321 is mounted on the bearing 322. The assembled support 21 and transducer body 22 and other components are then passed through the upper shell of the water tank 11 and connected to the bearing 322.

[0071] The above description is merely a preferred embodiment of the present invention and does not limit the patent scope of the present invention. Any equivalent structural transformations made using the contents of the present invention's specification and drawings under the technical concept of the present invention, or direct / indirect applications in other related technical fields, are included within the patent protection scope of the present invention.
