Description

Technical Field

[0001] This invention belongs to the field of ultrasonic technology, and particularly relates to an ultrasonic generating component and ultrasonic device. Background Technology

[0002] An ultrasonic generator is a component used in ultrasonic devices to output ultrasonic waves. It converts electrical energy into high-frequency mechanical vibration energy (ultrasonic waves) through a transducer and emits it into the working medium. In related technologies, the area covered by a single ultrasonic wave emitted from a single location by an ultrasonic generator is relatively small, meaning the energy output efficiency of the ultrasonic generator is low. The only way to increase the coverage area per emission is to increase the number of transducers, but this results in a larger volume at the transmitting end of the ultrasonic generator, making it inconvenient for users to store and unsuitable for use with small working media.

[0011] In some embodiments, the ultrasonic generating component further includes a detection component mounted on the housing, for detecting whether the output element is in an initial position on the first plane, the initial position being the position of the output element before it is driven on the first plane.

The other end of the sliding member is connected to the output component, allowing the output component to move with the sliding member in a first plane, either closer to or away from the axis of the rotating shaft, thereby outputting a helical motion path in the first plane.

[0036] This invention provides an ultrasound generating component 10 for generating ultrasound waves in an ultrasound device. The ultrasound device can be a beauty instrument that uses high-frequency ultrasound waves to act on the skin for cosmetic purposes, an ultrasound X-ray diagnostic instrument that uses high-frequency ultrasound waves for imaging, or an ultrasonic cleaner that uses the cavitation effect generated by ultrasound waves for cleaning. Regardless of the specific type of ultrasound device, the ultrasound generating component 10 can be used to generate ultrasound waves. It should be noted that the application scenario of this invention does not limit the structure of the ultrasound generating component 10 and the ultrasound device.

[0037] For ease of explanation, the following explanation and illustration will use an ultrasonic device as an example of a beauty instrument.

[0038] like Figures 1-3 As shown, the ultrasonic generating assembly 10 provided in this embodiment of the invention includes a housing 1, an output component 2, a motor 3, a rotating shaft 41, a track disk 42, and a sliding device. The sliding device includes a slide rail 43 and a sliding element 44. The housing 1 forms the mounting base for each component. Figure 3 for Figure 2 A cross-sectional view along the AA direction.

[0039] like Figure 3 As shown, output component 2 is used to generate ultrasonic waves; that is, output component 2 includes a transducer 21, which can convert electrical energy into high-frequency mechanical vibration ultrasonic energy. Motor 3 is fixed to housing 1 and provides the power source. Figure 4 and Figure 5As shown, the assembly consisting of the rotating shaft 41, track disk 42, slide rail 43, and sliding member 44 can be defined as the power output assembly 4 connected between the output member 2 and the motor 3. Among them, Figure 3 for Figure 1 Assembly diagram of the ultrasonic generator component 10 after removing the housing 1. Figure 4 This is an exploded view of the power output component 4.

[0040] like Figure 3 As shown, one end of the rotating shaft 41 is driven and connected to the motor 3, and the other end is spaced apart from the output component 2. That is, the rotating shaft 41 is directly driven by the motor 3 and rotates with the output shaft of the motor 3, but the rotation of the rotating shaft 41 cannot directly drive the output component 2 to rotate.

[0041] like Figure 5 and Figure 6 As shown, the track disk 42 is coaxially arranged with the rotating shaft 41 and rotates at a different speed. That is, the track disk 42 is through which the rotating shaft 41 passes and is clearance-fitted with the rotating shaft 41, meaning that the track disk 42 does not rotate synchronously with the rotating shaft 41. The track disk 42 includes a guide structure 421 extending around the rotating shaft 41 in a helical trajectory, that is, the axis of the rotating shaft 41 is the center point of the helix. It can be understood that the helix is ​​a planar helix, including but not limited to Archimedean spirals, logarithmic spirals, and hyperbolic spirals.

[0042] It should be noted that Figure 4 and Figure 5 The perspective shown is opposite; if we take... Figure 4 The perspective is defined as a top-down perspective, then Figure 5 The perspective will be from bottom to top.

[0043] The slide rail 43 is coaxially arranged with the rotating shaft 41 and rotates differentially relative to the track disk 42. That is, the rotating shaft 41 directly drives the slide rail 43 to rotate, and the slide rail 43 rotates synchronously with the rotating shaft 41 around its axis. The track disk 42 rotates with the slide rail 43, but is not directly driven by the rotating shaft 41; it is only driven to rotate after the slide rail 43 has rotated, and a differential rotation occurs between the track disk 42 and the slide rail 43. It can be understood that the extension direction of the axis of the rotating shaft 41 is perpendicular to the first plane. The slider 44 is slidably arranged along the slide rail 43, with one end extending to the track disk 42 and sliding along the guide structure 421. The other end of the slider 44 is connected to the output component 2, so that the output component 2 moves with the slider 44 in the first plane, either close to or away from the axis of the rotating shaft 41, thereby outputting a spiral motion path in the first plane. The output component 2 can be translated on the first plane and rotated about the first direction using only one motor 3. This eliminates the need for a separate motor 3 for translation and another for rotation, reducing the number of components in the ultrasonic generator assembly 10, simplifying wiring and maintenance costs, and lowering production costs and overall size. Furthermore, since only one motor 3 is needed to drive rotation and translation, the structure is simpler and easier to implement.

[0044] Thus, even if the position of the housing 1 on the first plane remains unchanged, the output component 2 can emit ultrasonic waves at multiple positions while rotating and translating, allowing the ultrasonic energy to cover a larger area and expanding the effective radiation area of ​​the ultrasonic generating component 10. Furthermore, because the output component 2 performs two movements, the transducer 21 vibrates not just with a single amplitude or frequency, but with a multi-dimensional superposition of vibrations. This more effectively excites the piezoelectric effect of the piezoelectric material, increasing the vibration intensity and thus enhancing the ultrasonic output. The two movements can also significantly alter the vibration direction of the transducer 21, adjusting its resonant state, reducing the loss of ultrasonic energy at non-resonant frequencies, and concentrating the ultrasonic energy in the output area, thereby increasing the ultrasonic energy density of a single output from the ultrasonic generating component 10.

[0045] It should be noted that the first plane does not refer to a single plane with a fixed position, but rather to a set of multiple parallel planes, as illustrated in the schematic diagram of this application. Figure 2 The paper plane shown is the first plane.

[0046] Output component 2 moves along the sliding component 44 on the first plane, outputting a spiral-shaped motion path. Output component 2 continuously changes position on the first plane along the guide structure 421, making it difficult for incident and reflected waves to stably superimpose at a fixed position, thus reducing the generation of standing waves. The continuous and curved nature of the spiral itself reduces the positional overlap of ultrasonic energy on the first plane, minimizing dead zones in the coverage of ultrasonic energy in space. From the center to the edge of the spiral, the radius of rotation gradually increases. Output component 2 moves slower and has a longer dwell time in the central region near the center of the spiral, resulting in a larger total amount of ultrasonic energy applied to that region. Output component 2 rotates faster in the peripheral region near the edge of the spiral, with a relatively shorter dwell time per unit area. However, it should be noted that the relatively shorter dwell time in the peripheral region does not mean that the ultrasonic energy is not concentrated in the peripheral region. Output component 2 can move to the peripheral region and output ultrasonic waves in a concentrated manner there, thus allowing ultrasonic energy to be concentrated in both the central and peripheral regions. The output component 2 has different speeds in the central and peripheral regions of the spiral. This speed variation characteristic makes the ultrasonic energy distribution more in line with the actual requirement of "stronger at the center and weaker at the periphery," reducing the waste of ultrasonic energy caused by excessive lingering in the peripheral region and improving the overall effective utilization rate of ultrasonic energy. In addition, the track disk 42 also rotates, allowing the output component 2 to adapt more smoothly to the changes in the geometry of the spiral trajectory, moving more smoothly and evenly along the spiral trajectory of the guide structure 421. This improves the continuity and accuracy of the motion path formed by the output component 2 on the first plane, enabling the output component 2 to achieve efficient and stable spiral motion on the first plane.

[0047] The ultrasonic generator assembly 10 provided in this embodiment of the invention includes a housing 1, a motor 3, a rotating shaft 41, an output component 2, a track disk 42, and a sliding device. The sliding device includes a slide rail 43 and a sliding member 44. The motor 3 is fixed to the housing 1. The output component 2 is used to output ultrasonic waves. One end of the rotating shaft 41 is driven and connected to the motor 3, and the other end of the rotating shaft 41 is spaced apart from the output component 2. The track disk 42 is coaxially arranged with the rotating shaft 41 and rotates at a differential speed. The track disk 42 includes a guide structure 421 extending around the rotating shaft 41 in a spiral trajectory. The slide rail 43 is coaxially arranged with the rotating shaft 41 and rotates at a differential speed relative to the track disk 42. The sliding member 44 is slidably arranged along the slide rail 43. One end of the sliding member 44 extends to the track disk 42 and slides along the guide structure 421. The other end of the sliding member 44 is connected to the output component 2, so that the output component 2 moves with the sliding member 44 in a first plane, either close to or away from the axis of the rotating shaft 41, thereby outputting a spiral motion path in the first plane.

[0048] Thus, firstly, the output component 2 continuously changes position on the first plane along the spiral trajectory of the guide structure 421, allowing ultrasonic energy to cover a larger area and expanding the effective radiation area of ​​the ultrasonic generating component 10. Because the output component 2 rotates and translates during its movement along the spiral trajectory of the guide structure 421, the transducer 21 vibrates and superimposes in multiple dimensions, enhancing ultrasonic output, adjusting the resonant state of the transducer 21, and increasing the ultrasonic energy density of a single output from the ultrasonic generating component 10. Secondly, the continuous and curved nature of the spiral itself reduces the positional overlap of ultrasonic energy on the first plane, reducing dead zones in spatial coverage; the output component 2 has different speeds in the central and peripheral regions of the spiral, reducing the waste of ultrasonic energy caused by excessive dwell in the peripheral region. Thirdly, a single motor 3 can realize the translation of the output component 2 on the first plane and its rotation around the first direction, reducing the number of components in the ultrasonic generating component 10, lowering the wiring difficulty and maintenance cost of the motor 3, and also reducing the production cost and assembled size of the ultrasonic generating component 10. Fourthly, the track disk 42 also rotates, allowing the output component 2 to adapt more smoothly to changes in the geometry of the spiral trajectory, enabling it to move more smoothly and fluidly along the spiral trajectory of the guide structure 421. This improves the continuity and accuracy of the motion path formed by the output component 2 on the first plane. In summary, the ultrasonic generator assembly 10 outputs a higher ultrasonic energy density, a higher matching resonant frequency, and less ultrasonic energy loss in a single pass, thus improving the energy output efficiency of the ultrasonic generator assembly 10.

[0049] In some embodiments, such as Figure 5 and Figure 6 As shown, the guide structure 421 is a groove, and the slider 44 includes a body 441 and a connector 442. The body 441 is fixed to the output component 2 and slides relative to the slide rail 43. At least a portion of the connector 442 protrudes from the body 441. That is, the connector 442 is installed on the body 441, and either all or part of the connector 442 protrudes from the body 441. The slide rail 43 has a groove 431 for the body 441 to slide, and the connector 442 passes through the groove 431 and is inserted into the guide structure 421. In this way, the connector 442 is inserted into the groove, and the sidewall of the groove restricts the position of the connector 442, providing a guiding effect for the movement of the connector 442, so that the slider 44 moves relatively smoothly along the spiral trajectory of the guide structure 421. Furthermore, the groove does not protrude from the surface of the track disk 42, allowing the surface of the track disk 42 with the guide structure 421 to maintain a high degree of flatness, which facilitates the assembly of the track disk 42 with other parts.

[0050] It is understandable that one end of connector 442 ( Figure 6The upper end of the connector 442 forms one end of the aforementioned slider 44 and extends to the track disk 42; the other end of the connector 442 ( Figure 6 The lower end of the middle connector 442 forms the other end of the aforementioned sliding member 44 and is connected to the output member 2.

[0051] In some embodiments, such as Figure 5 and Figure 6 As shown, one end of the slide rail 43 is fixedly connected to the rotating shaft 41, and the other end of the slide rail 43 is provided with a slot 432. The one end and the other end of the slide rail 43 are opposite ends in the extension direction of the slide rail 43, and the length direction of the slide rail 43 is the direction of its maximum profile dimension in the three-dimensional coordinate system. Figure 6 The width direction of the paper shown is the length direction of the slide rail 43, and also the extension direction of the slide rail 43.

[0052] like Figure 5 and Figure 6 As shown, the slot 432 engages with the edge of the track disk 42 and slides along the edge of the track disk 42. The other end of the slide rail 43 rotates around the pivot 41 along the edge of the track disk 42, thereby driving the slider 44, which is inserted into the slot 431, to rotate around the pivot 41. At the same time, the slider 44 is guided by the guide structure 421 on the track disk 42 and slides relative to the slide rail 43 within the slot 431. The fixed position of one end of the slide rail 43 with the pivot 41 forms the rotation center of the slide rail 43, and the other end of the slide rail 43 engages with the edge of the track disk 42, forming the support point of the slide rail 43. Furthermore, the slide rail 43 is engaged with the edge of the track disk 42 by opening a slot 432. The direction of the centrifugal force of the slide rail 43 is the direction in which the slot 432 engages with the edge of the track disk 42. The slide rail 43 is reliably connected to the edge of the track disk 42, which not only realizes the rotation of the slide rail 43 around the rotating shaft 41, but also improves the smoothness and reliability of the rotation of the slide rail 43. Moreover, the structure is simple and easy to implement.

[0053] In some embodiments, such as Figure 3 and Figure 4As shown, the ultrasonic generating assembly 10 also includes a transmission assembly 5, which is rotatably connected to the housing 1. The transmission assembly 5 is driven by both the rotating shaft 41 and the track disk 42. Through the transmission assembly 5, the rotating shaft 41 indirectly drives the track disk 42 to rotate. The transmission assembly 5 includes a driving gear 51, a driven gear 52, and a differential gear 53. The driving gear 51 is sleeved on the rotating shaft 41 and fixedly connected to it, meaning the rotating shaft 41 directly drives the driving gear 51 to rotate. The driven gear 52 is clearance-fitted to the rotating shaft 41 and fixedly connected to the track disk 42. That is, the driven gear 52 is sleeved on the rotating shaft 41 and spaced radially from the rotating shaft 41. The driven gear 52 does not rotate synchronously with the rotating shaft 41, but it drives the track disk 42 and rotates synchronously with it. The differential gear 53 is located on one side of the rotating shaft 41 and is rotatably connected to the housing 1. The differential gear 53 meshes with both the driving gear 51 and the driven gear 52. By using the differential gear 53, the rotational speed of the driven gear 52 is different from that of the driving gear 51, thereby creating a speed difference between the rotational speed of the track disk 42 and the rotational speed of the shaft 41. The speed distribution between the driving gear 51 and the driven gear 52 can be adjusted as needed, reducing the mechanical stress caused by the speed mismatch between the driving gear 51 and the driven gear 52, providing a smoother, safer and more efficient power transmission, and facilitating the movement of the output component 2 along the spiral trajectory on the first plane.

[0054] In some embodiments, such as Figure 3 and Figure 6 As shown, the ultrasonic generating assembly 10 also includes a first bearing 6, which is located between the rotating shaft 41 and the track disk 42. The track disk 42 is interference-fitted with the outer circumferential surface of the first bearing 6, and the rotating shaft 41 is interference-fitted with the inner circumferential surface of the first bearing 6, so that the transmission assembly 5 drives the track disk 42 to rotate and generate relative rotation with the rotating shaft 41. The first bearing 6 supports the rotating shaft 41 and the track disk 42, so that the track disk 42 is mounted on the rotating shaft 41 but does not rotate with the rotating shaft 41. The relative rotation between the track disk 42 and the rotating shaft 41 can create a speed difference between the rotational speed of the track disk 42 and the rotational speed of the rotating shaft 41. The structure is simple and easy to implement. The support and limiting of the first bearing 6 also improves the coaxiality of the rotating shaft 41 and the track disk 42, reduces the possibility of the rotating shaft 41 and the track disk 42 being misaligned along the axis of the rotating shaft 41, and improves the accuracy of the driving connection between the rotating shaft 41 and the track disk 42 and the transmission assembly 5, so that both the rotating shaft 41 and the track disk 42 can rotate relatively stably.

[0055] In some embodiments, such as Figure 6 and Figure 7As shown, the output component 2 includes a transducer 21, a cable 22, a connector 23, and a second bearing 24. The cable 22 is connected to the transducer 21 to transmit electrical energy to the transducer 21, enabling the transducer 21 to convert the electrical energy into vibrational ultrasonic energy (ultrasonic waves). The connector 23 is fixed to the transducer 21, thereby causing the transducer 21 to switch positions. The cable 22 passes through the connector 23. This can be achieved by the connector 23 having a through-hole for the cable 22 to pass through, or by the connector 23 having a slot or opening for the cable 22 to pass through, or by the cable 22 bypassing the connector 23. In the exemplary solution shown in the schematic diagram of this application, the connector 23 has a through-slot 231. One end of the cable 22 is connected to the transducer 21 within the through-slot 231, and the other end of the cable 22 passes through the housing 1 to the outside of the housing 1 to connect with the circuit outside the housing 1.

[0056] like Figure 6 and Figure 7 As shown, the second bearing 24 is located between the connecting member 23 and the sliding member 44. One of the inner and outer circumferential surfaces of the second bearing 24 is interference-fitted with the connecting member 23, and the other is interference-fitted with the sliding member 44, so that the connecting member 23 is mounted on the sliding member 44 via the second bearing 24. As the sliding member 44 changes position on the first plane, relative rotation occurs between the connecting member 23 and the sliding member 44. Specifically, the connecting member 23 may be interference-fitted with the inner circumferential surface of the second bearing 24, and the sliding member 44 may be interference-fitted with the outer circumferential surface of the second bearing 24; or the sliding member 44 may be interference-fitted with the inner circumferential surface of the second bearing 24, and the connecting member 23 may be interference-fitted with the outer circumferential surface of the second bearing 24. Regardless of which of the above methods the second bearing 24 is assembled between the connecting member 23 and the sliding member 44, as long as relative rotation occurs between the connecting member 23 and the sliding member 44 via the second bearing 24, it is acceptable.

[0057] In other words, connector 23 is mounted on slider 44 via second bearing 24 and can rotate freely relative to slider 44. After cable 22 is connected to the external circuit, the position of cable 22 is restricted, and cable 22 is stretched, which provides a force to restrict connector 23's movement in its circumferential direction, thus limiting connector 23's degree of freedom in its circumferential direction. Connector 23 rotates relative to slider 44 via second bearing 24. Even if slider 44 translates while rotating around axis 41 with slide rail 43, connector 23 is stretched by cable 22 and does not rotate around its own axis when changing position in the circumferential direction of axis 41. That is, transducer 21 revolves around axis 41 but does not rotate around its own axis. In addition, the relative rotation between slider 44 and connector 23 is achieved more smoothly through second bearing 24, reducing wear between slider 44 and connector 23.

[0058] This configuration eliminates the need for a long cable 22 to connect the transducer 21 for rotation around its own axis, and also eliminates the need to prevent the transducer 21 from winding by alternating forward and reverse rotation. This reduces the control difficulty of the transducer 21 and its wiring complexity. While reducing the possibility of transducer 21 winding, the transducer 21 can also switch positions via the slider 44 and the slide rail 43. The placement of the cable 22 has minimal impact on the position switching of the transducer 21, facilitating wiring and allowing the transducer 21 to switch positions by rotation and translation on the first plane.

[0059] In some embodiments, such as Figure 3 and Figure 4 As shown, the ultrasonic generator assembly 10 also includes a detection assembly 7, which is mounted on the housing 1. The detection assembly 7 can detect whether the output component 2 is in an initial position on the first plane, which is the position of the output component 2 on the first plane before it is driven. It can be understood that the initial position is a preset, fixed, and safe position. The signal generated by the detection assembly 7 can determine whether the output component 2 is in a known initial position before each activation of the ultrasonic generator assembly 10. This helps maintain consistent output parameters of the ultrasonic energy output by the ultrasonic generator assembly 10 each time it is activated, reducing the possibility of unstable or failed ultrasonic energy output due to positional deviation of the output component 2, and improving the accuracy of ultrasonic energy output.

[0060] In some embodiments, such as Figure 8 and Figure 9 As shown, the detection assembly 7 includes a first circuit board 71, a first detection element 72, and a second detection element 73. The first detection element 72 and the second detection element 73 are mounted on the first circuit board 71 at intervals. The two detection elements share a single circuit board, reducing the number of circuit boards and making the structure more compact. Specifically, both the first detection element 72 and the second detection element 73 can be mounted on the side of the first circuit board 71 facing the output component 2. It is understood that the first detection element 72 and the second detection element 73 are located on the side of the track disk 42 without the guide structure 421. Therefore, to facilitate illustrating the relative positions of the guide structure 421, the first detection element 72, and the second detection element 73, Figure 9 The trajectory disk 42 in the diagram is shown in perspective.

[0061] like Figure 6 and Figure 9As shown, the slider 44 includes a connector 442 slidably connected to the guide structure 421. Specifically, the slider 44 includes a body 441 and a connector 442. The body 441 is fixed to the output member 2 and slides relative to the slide rail 43. At least a portion of the connector 442 protrudes from the body 441. The slide rail 43 has a groove 431 for the body 441 to slide. The connector 442 passes through the groove 431 and is inserted into the guide structure 421. Therefore, the position change of the connector 442 reflects the position change of the connector 442. When the output member 2 is in the initial position, the connector 442 triggers the first detection element 72 to generate a first presence signal. The first presence signal can be used to determine whether the slider 44 has been reset.

[0062] like Figure 8 and Figure 9 As shown, one of the track disk 42 and the slide rail 43 is equipped with a second sensor 422. The second sensor 422 triggers the second detection element 73 to generate a second presence signal. The connector 442 is located at the outer end of the spiral trajectory of the guide structure 421. The outer end of the spiral trajectory of the guide structure 421 represents the outer endpoint of the spiral in polar coordinates, which is also the angle point corresponding to the maximum radius. Figure 6 and Figure 9 In the diagram, the outer end of the spiral trajectory of the guide structure 421 is represented by D. It can be understood that when the connector 442 is located at the outer end of the spiral trajectory of the guide structure 421, the output component 2 is in its initial position. Specifically, the track disk 42 may be equipped with a second sensor 422, and the second presence signal can determine whether the guide structure 421 is reset. It can be understood that in an implementation where the track disk 42 also rotates, the track disk 42 also needs to be reset. Alternatively, the slide rail 43 may be equipped with a second sensor 422, and the second presence signal can determine whether the slide rail 43 is reset. However, regardless of whether the track disk 42 or the slide rail 43 is equipped with a second sensor 422, the second presence signal can assist the first presence signal in determining whether the connector 442 has reset to the outer end of the spiral trajectory of the guide structure 421. In the schematic diagram shown in this application, the second sensor 422 is disposed on the track disk 42.

[0063] Thus, only when both the first and second presence signals are generated can it be considered that the output component 2 has been successfully reset. The first presence signal comes from the first detection element 72, and the second presence signal comes from the second detection element 73. Both signals jointly confirm the initial position of the output component 2 on the first plane, enabling a more accurate determination of the state of "output component 2 reset to the initial position," thereby avoiding the misjudgment that the reset is complete before the output component 2 is in position. Through the complementarity of the two signals, the impact of single-point failures on system function can be reduced, improving overall reliability. Furthermore, the linearity and / or rotation of the output component 2 can be more reliably coupled and detected, ensuring that the reset logic is triggered only when the physical position reaches the set alignment. The mutual verification of the two elements can suppress false signals caused by noise and interference, improving the accuracy and precision of the output component 2 reset, reducing false triggering and positional deviation accumulation when the output component 2 has not yet been successfully reset, and enhancing the operational safety of the ultrasonic generator assembly 10.

[0064] Specifically, such as Figure 6 and Figure 8 As shown, the connector 442 and / or the second sensing element 422 are magnets. It is possible that the connector 442 is a magnet, the second sensing element 422 is a magnet, or both the connector 442 and the second sensing element 422 are magnets. For ease of understanding, this invention provides an exemplary solution where both the connector 442 and the second sensing element 422 are magnets. The first detection element 72 and the second detection element 73 are both based on the Hall effect, detecting changes in the magnetic field and converting these changes into electrical signals. The Hall effect refers to the voltage difference generated in the direction perpendicular to the current and the magnetic field when a current flows through a conductor placed in a magnetic field. It can be understood that, based on the Hall effect, the first detection element 72 generates a first electrical signal in real time according to the position of the connector 442, and the second detection element 73 generates a second electrical signal in real time according to the position of the second sensing element 422. However, the first electrical signal will only switch to a first presence signal, and the second electrical signal will only switch to a second presence signal, when the connector 442 is located at the outer end of the spiral trajectory of the guide structure 421.

[0065] In some embodiments, such as Figure 3 and Figure 4As shown, the rotating shaft 41 is slidably connected to the output shaft of the motor 3. The ultrasonic generating assembly 10 also includes a lifting drive source 8 and a lifting component 9. The lifting drive source 8 is fixed to the housing 1, and the lifting component 9 is driven by the lifting drive source 8 and connected to the rotating shaft 41. The lifting component 9 drives the rotating shaft 41 to move up and down along a first direction, which is perpendicular to the first plane. Thus, even if the height of the housing 1 in the first direction remains unchanged, the ultrasonic energy can be kept concentrated at multiple heights in the first direction by adjusting the height of the output component 2 in the first direction. That is, the focusing height of the ultrasonic energy of the output component 2 is adjustable, allowing the ultrasonic generating assembly 10 to adapt to different depths of skin layers for treatment. Combined with the two-dimensional movement of the output component 2 on the first plane, the output component 2 can achieve three-dimensional spiral movement in space, which can efficiently cover and adjust the focusing height, realizing the efficient transmission and coverage of ultrasonic energy in space.

[0066] It is understandable that the extension direction of the axis of rotation 41 is in the first direction, in Figure 1 and Figure 3 In the diagram shown, N1 represents the first direction, which is perpendicular to... Figure 2 The direction of the paper's extension.

[0067] Specifically, such as Figure 3 and Figure 5 As shown, one end of the rotating shaft 41 is connected to a bushing 31. Both the output shaft of the motor 3 and the rotating shaft 41 are inserted into the bushing 31 and are engaged with the bushing 31 circumferentially. Specifically, both the rotating shaft 41 and the output shaft of the motor 3 have limiting grooves, so that both the rotating shaft 41 and the output shaft of the motor 3 have limiting surfaces 411 extending along a first direction. There can be only one limiting surface 411 or multiple limiting surfaces 411, so that both the rotating shaft 41 and the output shaft of the motor 3 can be inserted into the bushing 31 along the first direction and engaged with the bushing 31 circumferentially. That is, the rotating shaft 41 and the output shaft of the motor 3 are driven by the rotating shaft 41, so that the rotating shaft 41 rotates synchronously with the output shaft of the motor 3.

[0068] At least one of the rotating shaft 41 and the output shaft of the motor 3 is slidably connected to the bushing 31 along a first direction. Specifically, the rotating shaft 41 may be slidably connected to the bushing 31, while the output shaft of the motor 3 may be fixed to the bushing 31; the output shaft of the motor 3 may be slidably connected to the bushing 31, while the rotating shaft 41 may be fixed to the bushing 31; or both the rotating shaft 41 and the output shaft of the motor 3 may be slidably connected to the bushing 31. In this way, while realizing the driving connection between the rotating shaft 41 and the output shaft of the motor 3, the bushing 31 also realizes the lifting and lowering of the rotating shaft 41 relative to the output shaft of the motor 3 in the first direction. The structure is simple and easy to implement.

[0069] In some embodiments, such as Figure 4As shown, the ultrasonic generating assembly 10 also includes a detection assembly 7, which is mounted on the housing 1. The detection assembly 7 detects the lifting height of the lifting assembly 9 in the first direction. The lifting height of the lifting assembly 9 can be determined based on the lifting height signal generated by the detection assembly 7, thereby determining the lifting height of the output component 2 in the first direction. This ensures that ultrasonic energy is released at a predetermined height, preventing it from acting too deeply or too shallowly on the working medium (e.g., skin), improving the accuracy of the ultrasonic waves acting on the target area, and thus enhancing the stability and consistency of the ultrasonic action. Furthermore, the signal generated by the detection assembly 7 can detect whether the output component 2 deviates from the preset height in a timely manner, triggering an alarm or automatic shutdown, preventing equipment damage or unexpected operation caused by abnormal lifting height of the output component 2.

[0070] It should be noted that, in the embodiment where the ultrasonic generating component 10 is equipped with a lifting drive source 8 and a lifting component 9, the detection component 7 can detect only whether the output component 2 is in the initial position on the first plane, and the detection component 7 can detect only the lifting height of the lifting component 9 in the first direction. The detection component 7 can also integrate both detection functions, and be divided into two detection modules: the first detection module detects whether the output component 2 is in the initial position on the first plane, and the second detection module detects the lifting height of the lifting component 9 in the first direction.

[0071] In some embodiments, such as Figure 4 As shown, the lifting assembly 9 includes a third sensing element 92 that moves up and down along the first direction with the rotating shaft 41. The detection assembly 7 also includes a second circuit board 74 and a third detection element 75. The second circuit board 74 is fixed to the housing 1, and the third detection element 75 is installed on the second circuit board 74. Specifically, the third detection element 75 is installed on the side of the second circuit board 74 facing the lifting assembly 9.

[0072] The third detection element 75 and the third sensing element 92 magnetically sense each other and generate a lifting height signal. This lifting height signal is used to provide feedback on the height information of the output element 2 as it rises or falls along the first direction. That is, the third sensing element 92 is a magnetic object, and the third detection element 75 detects the position of the third sensing element 92 based on the Hall effect. For example, the third sensing element 92 can be a magnet.

[0073] Thus, the third detection element 75 can provide continuous and linear height information based on the Hall effect, forming a closed-loop control signal for the output element 2 in the first direction. Through real-time height feedback, the control system can precisely adjust the lifting distance of the output element 2 in the first direction, ensuring that the output element 2 outputs energy within a predetermined height range, improving the alignment accuracy and emission consistency of ultrasonic energy output. By continuously monitoring the lifting height, abnormal height, jamming, magnetic circuit misalignment, or detection signal failure can be quickly detected, triggering self-diagnosis or safety protection logic to avoid damage or safety risks caused by the output element 2 operating at a non-ideal height. Furthermore, the Hall signal supports adaptive or calibration mechanisms, allowing height-signal characteristic calibration to be performed during system manufacturing or maintenance, establishing a calibration curve between height and the Hall signal, thereby achieving higher linearity and repeatability.

[0074] Specifically, such as Figure 3 and Figure 4 As shown, the lifting assembly 9 also includes a lifting plate 91, which is driven by the output shaft of the lifting drive source 8 to move up and down in a first direction. Specifically, the lifting plate 91 can be threadedly connected to the output shaft of the lifting drive source 8, so that the lifting plate 91 moves up and down with the rotation of the output shaft of the lifting drive source 8. The lifting plate 91 is engaged between the two stepped surfaces 412 of the rotating shaft 41 and has a clearance fit with the rotating shaft 41, so that the rotating shaft 41 can rotate relative to the lifting plate 91 and move up and down with the lifting plate 91. The third detection element 75 is installed on the lifting plate 91, and the lifting plate 91 drives the third sensing element 92 and the rotating shaft 41 to move up and down synchronously.

[0075] like Figure 10 As shown, this embodiment of the invention also provides an ultrasonic device, including the aforementioned ultrasonic generating component 10. The ultrasonic device further includes a device body 20, a controller 30, and a switch 40. Because the ultrasonic device has the aforementioned ultrasonic generating component 10, it has the same technical effects as the aforementioned ultrasonic generating component 10, namely, a higher ultrasonic energy density output per pulse, a higher matchable resonant frequency, less ultrasonic energy loss, and higher ultrasonic energy output efficiency, achieving efficient transmission and coverage of ultrasonic energy, and facilitating user operation.

[0076] like Figure 10 As shown, both the ultrasonic generator assembly 10 and the switch 40 are mounted on the device body 20. The switch 40 is mounted on the surface of the device body 20, with a portion of the switch 40 exposed on the surface for user operation. The controller 30 is electrically connected to both the switch 40 and the ultrasonic generator assembly 10, and is triggered by the switch 40 to control the ultrasonic generator assembly 10. It should be noted that... Figure 10 The dashed lines in the diagram only indicate electrical connections and do not refer to specific parts. Figure 10 The two components connected at both ends of the same dotted line are electrically connected.

[0077] Specifically, the control functions of switch 40 include, but are not limited to, turning output device 2 on and off, adjusting the ultrasonic energy output frequency of output device 2, adjusting the ultrasonic energy output time of output device 2, turning on and off lifting drive source 8, adjusting the lifting height of lifting assembly 9, and turning motor 3 on and off.

[0078] By controlling the switch 40, the controller 30 can drive the ultrasonic generator component 10 and adjust the working state of the ultrasonic generator component 10, making it convenient for users to operate. The switch 40 can also adjust the ultrasonic generator component 10 to different working states so that the ultrasonic generator component 10 works in the expected state. This allows the ultrasonic generator component 10 to output ultrasonic energy more accurately and concentrate the ultrasonic energy on the target position in space, reducing the loss of ultrasonic energy at unexpected positions and achieving efficient transmission and coverage of ultrasonic energy.

[0079] In some embodiments, such as Figure 10 As shown, switch 40 includes a power button 401 and an adjustment button 402. The power button 401 controls the power supply to the output device 2, and the adjustment button 402 adjusts the output frequency of the output device 2 to control the switching between continuous energy output and intermittent energy output states, and controls the spacing of the energy points output by the output device 2 in the intermittent energy output state. It should be noted that the continuous energy output state of the output device 2 means that the output device 2 continuously outputs ultrasonic energy during the time from activation to deactivation controlled by the power button 401. The intermittent energy output state of the output device 2 means that the output device 2 intermittently outputs ultrasonic energy during the time from activation to deactivation controlled by the power button 401.

[0080] By changing the output frequency of output component 2, the output path of ultrasonic energy on the first plane can be altered, forming point-interval energy paths or line-interval energy paths. It can be understood that multiple points or line segments combine to form a continuous path, which is the movement path of output component 2 on the first plane. Specifically, this path is the extended trajectory of guide structure 421, exhibiting a spiral shape. That is, controlled by switch 40, ultrasonic generating component 10 can output multiple energy paths to flexibly adapt to various user needs, reduce energy loss in unintended areas, concentrate energy in the target area, and improve the utilization rate of ultrasonic energy.

[0081] In some embodiments, such as Figure 4 and Figure 10As shown, the ultrasonic generating assembly 10 also includes a lifting drive source 8 and a lifting assembly 9. The lifting drive source 8 is fixed to the housing 1. The lifting assembly 9 is driven to the lifting drive source 8 and connected to the rotating shaft 41. The lifting assembly 9 drives the rotating shaft 41 to move up and down along a first direction, which is perpendicular to the first plane.

[0082] The switch 40 also includes two function keys 403, which control the start and stop of the lifting drive source 8 and the motor 3, respectively. Specifically, one function key 403 controls the start and stop of the lifting drive source 8 via the controller 30, causing the output component 2 to move up and down in the first direction; the other function key 403 controls the start and stop of the motor 3 via the controller 30, causing the output component 2 to move along the spiral trajectory of the guide structure 421 on the first plane. The embodiments provided by this invention can control the lifting drive source 8 and the motor 3 separately. The lifting drive source 8 can be started independently without starting the motor 3, causing the output component 2 to move up and down only in the first direction; the motor 3 can also be started independently without starting the lifting drive source 8, causing the output component 2 to move only along the spiral trajectory of the guide structure 421 on the first plane; and the lifting drive source 8 and the motor 3 can be turned off, causing the output component 2 to output ultrasonic energy at a fixed position in space. By triggering different function keys 403, the ultrasonic generating component 10 can output ultrasonic energy in different working modes, more flexibly adapting to various user needs, reducing energy loss of the motor 3 and the lifting drive source 8, and saving energy.

[0083] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
