[0002] An ultrasonic generator is a component used in ultrasonic devices to output ultrasonic waves. It converts electrical energy into high-frequency mechanical vibration ultrasonic energy (ultrasonic waves) through a transducer and emits it into the working medium. In related technologies, the radiation efficiency and coverage of the ultrasonic waves output by ultrasonic generators are relatively limited, and the ultrasonic energy is unevenly distributed across multiple locations in space. This prevents the ultrasonic energy from being concentrated and matched to the target area, affecting user experience. Utility Model Content

[0029] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments.

To avoid unnecessary repetition, the various possible combinations of the specific technical features in this utility model will not be described separately.

[0031] In the following description, the terms "first," "second," "etc." are used merely to distinguish different objects and do not indicate that the objects have the sameness or relationship. It should be understood that the directional descriptions "above," "below," "outside," and "inside" refer to the directions under normal use, while "left" and "right" refer to the left and right directions shown in the corresponding diagrams, which may or may not be the left and right directions under normal use.

[0032] It should be noted that the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a process, method, article, or apparatus. Unless otherwise specified, an element defined by the phrase "comprising one..." does not exclude the presence of other identical elements in the process, method, article, or apparatus that includes that element.

[0033] This invention provides an ultrasonic generating component 10 for generating ultrasonic waves in an ultrasonic device. The ultrasonic device can be a beauty instrument that uses high-frequency ultrasonic waves to act on the skin for cosmetic purposes, an ultrasonic X-ray diagnostic instrument that uses high-frequency ultrasonic waves for imaging, or an ultrasonic cleaner that uses the cavitation effect generated by ultrasonic waves for cleaning. Regardless of the specific type of ultrasonic device, the ultrasonic device can utilize the ultrasonic generating component 10 to generate ultrasonic waves. It should be noted that the application scenario of this invention does not limit the structure of the ultrasonic generating component 10 and the ultrasonic device.

[0034] For ease of explanation, the following explanation and illustration will use an ultrasonic device as an example of a beauty instrument.

[0035] like Figures 1-3 As shown, the ultrasonic generating assembly 10 provided in this embodiment of the present invention includes a housing 1, an output component 2, a motor 3, a power output assembly 4, and a detection assembly 9. Among them, Figure 3 for Figure 2 A cross-sectional view along the AA direction.

[0036] like Figure 3 As shown, the output device 2 is used to generate ultrasonic waves, that is, the output device 2 includes a transducer 21, which can convert electrical energy into high-frequency mechanical vibration ultrasonic energy.

[0037] Motor 3 is fixed to housing 1. Power output assembly 4 is driven by motor 3, meaning it is connected to and driven by the output shaft of motor 3. Power output assembly 4 is connected to output component 2. Driven by motor 3, power output assembly 4 causes output component 2 to translate and rotate around a first direction on a first plane, with the first direction perpendicular to the first plane. Therefore, the first direction can be understood as the direction of the rotation axis of power output assembly 4. In other words, output component 2 performs both rotational and translational motion on the first plane.

[0038] 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 by rotating and translating simultaneously through the power output component 4. The ultrasonic energy can cover a larger area in the first plane, 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 multi-dimensional vibration superposition. This more effectively excites the piezoelectric effect of the piezoelectric material, increasing vibration intensity and thus enhancing ultrasonic output. The two movements can further alter the vibration direction of the transducer 21, adjusting its resonant state, reducing ultrasonic energy loss at non-resonant frequencies, and concentrating ultrasonic energy in the output area, thereby increasing the ultrasonic energy density of a single output from the ultrasonic generating component 10. In summary, the ultrasonic generating component 10 has a higher ultrasonic energy density per output, a higher matching resonant frequency, and less ultrasonic energy loss, improving its energy output efficiency. Additionally, only one motor 3 is needed to drive the output component 2 for rotation and translation. The wiring difficulty and maintenance cost of the motor 3 are low, and the structure is simple and easy to implement.

[0039] 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. 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.

[0040] like Figure 3 and Figure 4 As shown, the detection component 9 is installed on the housing 1. The detection component 9 is used to detect whether the output component 2 is in its 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 component 9 can determine whether the output component 2 is in a known initial position before each activation of the ultrasonic generator 10. This helps maintain consistent output parameters of the ultrasonic energy output by the ultrasonic generator 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 the ultrasonic energy output.

[0041] The ultrasonic generating assembly 10 provided in this embodiment includes a housing 1, an output component 2, a motor 3, a power output assembly 4, and a detection assembly 9. The output component 2 generates ultrasonic waves. The motor 3 and the lifting drive source 5 are both fixed to the housing 1. The power output assembly 4 is driven and connected to the motor 3 and to the output component 2. The power output assembly 4 drives the output component 2 to translate on a first plane and rotate around a first direction. The detection assembly 9 is installed on the housing 1 and is used to detect whether the output component 2 is in its initial position on the first plane, which is the position of the output component 2 before it is driven on the first plane. Through the motor 3 and the power output assembly 4, the output component 2 rotates and translates on the first plane, allowing ultrasonic energy to cover a larger area in the first plane, thus expanding the effective radiation area of ​​the ultrasonic generating assembly 10. Furthermore, because the output component 2 performs two movements, the piezoelectric effect of the piezoelectric material can be more effectively excited, enhancing the ultrasonic output; the resonant state of the transducer 21 can also be adjusted, increasing the ultrasonic energy density of a single output of the ultrasonic generating assembly 10 and reducing ultrasonic energy loss. Furthermore, the signal generated by the detection component 9 can determine whether the output component 2 is in a known initial position before each activation of the ultrasonic generator component 10. This reduces the possibility of unstable or failed ultrasonic energy output due to positional deviation of the output component 2, and minimizes ultrasonic energy loss. In summary, the ultrasonic generator component 10 outputs a higher ultrasonic energy density per cycle, a higher matchable resonant frequency, and less ultrasonic energy loss. Moreover, the focused height of the ultrasonic energy is adjustable, achieving efficient transmission and coverage of ultrasonic energy, improving the energy output efficiency of the ultrasonic generator component 10, and facilitating user operation.

[0042] In some embodiments, such as Figures 3-5 As shown, the power output assembly 4 includes a rotating shaft 41, a track disk 42, and a sliding device. 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] like Figure 3 As shown, one end of the rotating shaft 41 is connected to the motor 3 for driving, and the other end is spaced apart from the output component 2. The output shaft of the motor 3 directly drives the rotating shaft 41 to rotate, but the rotating shaft 41 does not directly drive the output component 2. The track disk 42 is through which the rotating shaft 41 passes and is clearance-fitted with the rotating shaft 41, that is, 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.

[0044] The sliding device includes a slide rail 43 and a slider 44. The slide rail 43 is coaxially arranged with the rotating shaft 41 and rotates at a differential speed 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. Instead, it is driven to rotate only 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 in the aforementioned first direction.

[0045] The slider 44 is slidably disposed along the slide rail 43. One end of the slider 44 extends to the track disk 42 and slides 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 follows the slider 44 to move in the first plane, either close to or away from the axis of rotation of the shaft 41, thereby outputting a spiral motion path in the first plane. The translation of the output component 2 in the first plane and its rotation around the first direction can be realized by a single motor 3, eliminating the need for a separate motor for the translation of the output component 2 and another motor for its rotation. This reduces the number of components in the ultrasonic generator assembly 10, reduces the wiring difficulty and maintenance cost of the motor 3, and also reduces the production cost and assembled size of the ultrasonic generator assembly 10. Furthermore, since only one motor 3 is used to drive the rotation and translation of the output component 2, the structure is simpler and easier to implement.

[0046] Thus, by utilizing the continuous and curved characteristics of the spiral itself, the positional overlap of ultrasonic energy on the first plane is reduced, and the blind spots of ultrasonic energy coverage in space are decreased. The track disk 42 also rotates, allowing the output component 2 to adapt more smoothly to the geometric changes of the spiral trajectory, so as to move 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] It is understood that the position of the slider 44 reflects the position of the output component 2. Therefore, the detection component 9 can detect whether the output component 2 is in its initial position on the first plane by detecting the position of the slider 44. Specifically, the slider 44 includes a connector 442 that is inserted into the slide rail 43. The connector 442 is a magnet. The detection component 9 includes a first detection element 91. The first detection element 91 can detect the position of the connector 442 based on the Hall effect, thereby detecting the position of the output component 2 on the first plane. When the output component 2 is in its initial position, the connector 442 triggers the first detection element 91 to generate a first presence signal. The first presence signal can be used to determine whether the slider 44 has been reset, thereby determining whether the output component 2 is in its initial position.

[0048] Furthermore, another magnet (defined as the second magnet) can be provided on the track disk 42, and the detection component 9 also includes a second detection element 92. The second detection element 92 can detect the position of the track disk 42 based on the Hall effect. When the output component 2 is in the initial position, the magnet on the track disk 42 triggers the second detection element 92 to generate a second presence signal. Thus, only when both the first presence signal and the second presence signal are generated can it be considered that the output component 2 has been successfully reset. The first presence signal and the second presence signal jointly confirm the initial position of the output component 2 on the first plane, which can more accurately determine the state of "output component 2 reset to the initial position", thereby avoiding the misjudgment that the reset is completed before the output component 2 is in position. Through the complementarity of the two signals, the impact of single-point failure on system function can be reduced, false signals caused by noise and interference can be suppressed, false triggering and position deviation accumulation when the output component 2 has not been successfully reset can be reduced, and the operational safety of the ultrasonic generator component 10 can be improved.

[0049] In this configuration, when both the first and second presence signals are generated, the connector 442 is located at the outer end of the helical trajectory of the guide structure 421. The outer end of the helical trajectory of the guide structure 421 represents the outer endpoint of the helix in polar coordinates, which is also the angle point corresponding to the maximum radius. Figure 3 and Figure 5 In the diagram, the outer end of the spiral trajectory of the guide structure 421 is represented by C. It can be understood that when the connector 442 is located at the outer end of the spiral trajectory of the guide structure 421, it means that the output component 2 is in the initial position.

[0050] In some embodiments, such as Figure 4 and Figure 5 As shown, the power output assembly 4 includes a rotating shaft 41, a track disk 42, a slide rail 43, and a sliding member 44. 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.

[0051] like Figure 3As 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. The output shaft of the motor 3 directly drives the rotating shaft 41 to rotate, but the rotating shaft 41 does not directly drive the output component 2. The track disk 42 is through which the rotating shaft 41 passes and is clearance-fitted with the rotating shaft 41, that is, 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 spiral trajectory, that is, the axis of the rotating shaft 41 is the center point of the spiral. The slide rail 43 is driven and connected to the rotating shaft 41, and rotates around the axis of the rotating shaft 41 with the rotating shaft 41, that is, the slide rail 43 is directly driven by the rotating shaft 41 and rotates synchronously with the rotating shaft 41. The output component 2 is mounted on the sliding component 44, which rotates with the slide rail 43 and slides relative to the slide rail 43 along the spiral trajectory of the guide structure 421, either close to or away from the axis of the rotating shaft 41. It should be noted that in this embodiment, the track disk 42 may or may not rotate, as long as the slider 44 can rotate and translate along the spiral trajectory of the guide structure 421.

[0052] The sliding member 44 rotates and translates along the spiral trajectory of the guide structure 421, causing the output member 2 to move along the spiral trajectory in the first plane, forming a spiral motion path in the first plane. The output member 2 continuously changes position on the first plane along the guide structure 421, making it difficult for the incident and reflected waves to stably superimpose at a fixed position, thus reducing the generation of standing waves. From the center to the edge of the spiral, the radius of rotation gradually increases. The output member 2 moves slower and has a longer dwell time in the central region near the center of the spiral, resulting in a larger total ultrasonic energy applied to that region. The output member 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. The output member 2 can move to the peripheral region and output ultrasonic waves in a concentrated manner there, thus allowing the 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 needs of "strong in the center and weak in the periphery", reducing the waste of ultrasonic energy caused by excessive residence in the peripheral region and improving the overall effective utilization rate of ultrasonic energy.

[0053] In some embodiments, such as Figure 5 and Figure 6As 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.

[0054] In some embodiments, such as Figure 3 and Figure 4 As shown, the ultrasonic generating assembly 10 also includes a transmission assembly 7, which is rotatably connected to the housing 1. The transmission assembly 7 is driven to both the rotating shaft 41 and the track disk 42. Through the transmission assembly 7, the rotating shaft 41 indirectly drives the track disk 42 to rotate. There is a speed difference between the rotational speed of the track disk 42 and the rotational speed of the rotating shaft 41, that is, the track disk 42 and the rotating shaft 41 rotate at different speeds.

[0055] Specifically, such as Figure 3 and Figure 4 As shown, the transmission assembly 7 includes a driving gear 71, a driven gear 72, and a differential gear 73. The driving gear 71 is sleeved on and fixedly connected to the rotating shaft 41, meaning the rotating shaft 41 directly drives the driving gear 71 to rotate. The driven gear 72 is clearance-fitted to the rotating shaft 41 and fixedly connected to the track disk 42, meaning the driven gear 72 is sleeved on the rotating shaft 41 and spaced radially from the rotating shaft 41. The driven gear 72 does not rotate synchronously with the rotating shaft 41, but drives the track disk 42 and rotates synchronously with the track disk 42. The differential gear 73 is located on one side of the rotating shaft 41 and is rotatably connected to the housing 1. The differential gear 73 meshes with both the driving gear 71 and the driven gear 72. By using the differential gear 73, the rotational speed of the driven gear 72 is different from that of the driving gear 71, 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 71 and the driven gear 72 can be adjusted as needed, reducing the mechanical stress caused by the speed mismatch between the driving gear 71 and the driven gear 72, providing a smoother, safer and more efficient power transmission, and facilitating the movement of the output component 2 along a spiral trajectory on the first plane.

[0056] In some embodiments, such as Figure 3 and Figure 4As shown, the driven gear 72 is integrally formed on the side of the track disk 42 away from the output component 2. Thus, there is no gap between the driven gear 72 and the track disk 42, allowing the track disk 42 and the driven gear 72 to rotate more synchronously. This results in the track disk 42 rotating more smoothly with the driven gear 72, improving the smoothness of the track disk 42's movement, and consequently, further improving the smoothness of the output component 2's movement. Furthermore, it reduces the assembly operations between the driven gear 72 and the track disk 42, simplifying the assembly operations of the ultrasonic generator assembly 10.

[0057] In some embodiments, such as Figure 3 and Figure 4 As shown, the differential gear 73 includes a first gear 731 and a second gear 732 that are stacked and integrally formed. The first gear 731 meshes with the driven gear 72, and the second gear 732 meshes with the driving gear 71. Thus, there is no backlash between the first gear 731 and the second gear 732, reducing the loss of kinetic energy between them. This facilitates the efficient transfer of kinetic energy from the shaft 41 to the first gear 731, allowing the driven gear 72 to rotate smoothly with the first gear 731. This improves the smoothness of the movement of the track disk 42, further enhancing the smoothness of the movement of the output component 2, and simplifying the assembly operation of the gears in the differential gear 73.

[0058] In some embodiments, such as Figure 3 and Figure 6 As shown, the ultrasonic generating assembly 10 also includes a first bearing 8, 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 8, and the rotating shaft 41 is interference-fitted with the inner circumferential surface of the first bearing 8, so that the transmission assembly 7 drives the track disk 42 to rotate and generate relative rotation with the rotating shaft 41. The first bearing 8 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 8 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 drive connection between the rotating shaft 41 and the track disk 42 and the transmission assembly 7, so that both the rotating shaft 41 and the track disk 42 can rotate relatively stably.

[0059] 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 mounted on a sliding member 44 and changes position with the sliding member 44. 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, a slot or opening for the cable 22 to pass through, or 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.

[0060] 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 relative rotation can occur between the sliding member 44 and the connecting member 23. 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. However, 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 can occur between the connecting member 23 and the sliding member 44, it is acceptable.

[0061] In other words, although the connector 23 is mounted on the slider 44, it can still rotate freely relative to the slider 44. After the cable 22 is connected to the external circuit, the position of the cable 22 is restricted, and the cable 22 is stretched, which provides a force that restricts the movement of the connector 23 in its circumferential direction, thus limiting the degree of freedom of the connector 23 in its circumferential direction. The connector 23 rotates relative to the slider 44 through the second bearing 24. Even if the slider 44 translates while rotating around the axis of the shaft 41 with the slide rail 43, the connector 23 is stretched by the cable 22 and does not rotate around its own axis when the position of the shaft 41 changes in the circumferential direction. That is, the transducer 21 revolves around the axis of the shaft 41, but does not rotate around its own axis. In addition, the relative rotation between the slider 44 and the connector 23 is realized more smoothly through the second bearing 24, reducing the wear between the slider 44 and the connector 23.

[0062] 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.

[0063] In some embodiments, such as Figure 3 As 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 5 and a lifting component 6. The lifting drive source 5 is fixed to the housing 1, and the lifting component 6 is driven by the lifting drive source 5 and connected to the power output component 4. The lifting component 6 drives the power output component 4 to move up and down in the first direction. In this way, 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, which allows the ultrasonic generating assembly 10 to adapt to different depths of skin layers for treatment.

[0064] By combining the two-dimensional motion of the output component 2 on the first plane, the output component 2 can achieve three-dimensional spiral motion in space, which can not only provide efficient coverage but also adjust the focusing height, thus realizing the efficient transmission and coverage of ultrasonic energy in space.

[0065] In some embodiments, such as Figure 3 and Figure 4 As shown, the lifting assembly 6 includes a lifting plate 61, which is driven by the output shaft of the lifting drive source 5 to move up and down in a first direction. Specifically, the lifting drive source 5 can be a drive motor, and the lifting plate 61 can be threadedly connected to the output shaft of the lifting drive source 5, so that the lifting plate 61 moves up and down with the rotation of the output shaft of the lifting drive source 5. In some possible embodiments, the lifting drive source 5 can also be a cylinder, and the lifting plate 61 can be directly connected to the output shaft of the cylinder.

[0066] Specifically, such as Figure 3 and Figure 5As shown, the rotating shaft 41 has two stepped surfaces 411, which are spaced apart in the first direction. Specifically, a portion of the rotating shaft 41 located between the two stepped surfaces 411 forms a diameter difference with another portion, thus creating the stepped surfaces 411. The lifting plate 61 is clearance-fitted with the rotating shaft 41 and abuts against the two stepped surfaces 411. That is, the lifting plate 61 is sleeved on the portion of the rotating shaft 41 between the two stepped surfaces 411, and the two end faces of the lifting plate 61 in the first direction abut against the two stepped surfaces 411 respectively. In this way, the rotating shaft 41 can rotate relative to the lifting plate 61, and the lifting plate 61 can also drive the rotating shaft 41 to move up and down in the first direction. The structure is simple and easy to implement.

[0067] In some embodiments, such as Figure 3 As shown, the lifting assembly 6 also includes a plurality of guide posts 62 extending along the first direction. All guide posts 62 are fixedly connected to the housing 1 and slidably connected to the lifting plate 61. The guide posts 62 provide guidance and support in the first direction, reducing the possibility of the lifting plate 61 shifting relative to the first direction, thereby reducing the possibility of the rotating shaft 41 shifting relative to the first direction, improving the accuracy and precision of adjusting the focusing height, and facilitating the concentration of ultrasonic energy at the target height.

[0068] In some embodiments, 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 412 extending along a first direction. There can be only one limiting surface 412 or multiple limiting surfaces 412, 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.

[0069] 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.

[0070] In some embodiments, such as Figure 4As shown, the detection component 9 can detect the lifting height of the lifting component 6 in the first direction. The lifting height of the lifting component 6 can be determined based on the lifting height signal generated by the detection component 9, 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 superficially 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 component 9 can promptly detect whether the output component 2 deviates from the preset height, triggering an alarm or automatic shutdown, preventing equipment damage or unexpected operation caused by abnormal lifting height of the output component 2.

[0071] It can be understood that the position of the lifting plate 61 in the first direction reflects the position of the output component 2 in the first direction. Therefore, the detection component 9 can detect the lifting height of the output component 2 in the first direction by detecting the lifting height of the lifting plate 61. Specifically, the detection component 9 includes a third detection element 94 and a third magnet 95 mounted on the lifting plate 61. The third detection element 94 can detect the position of the third magnet 95 based on the Hall effect and generate a lifting height signal to provide feedback on the lifting height information of the output component 2 in the first direction.

[0072] like Figure 8 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 adjustable ultrasonic energy focusing height, achieving efficient ultrasonic energy transmission and coverage, and facilitating user operation.

[0073] like Figure 8 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 8 The dashed lines in the diagram only indicate electrical connections and do not refer to specific parts. Figure 8 The two components connected at both ends of the same dotted line are electrically connected.

[0074] 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 5, adjusting the lifting height of lifting component 6, and turning motor 3 on and off.

[0075] 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. By adjusting the ultrasonic generator component 10 to the expected working state through different switches 40, the ultrasonic generator component 10 can 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 realizing efficient transmission and coverage of ultrasonic energy.

[0076] Furthermore, by changing the output frequency of output component 2, the output path of ultrasonic energy on the first plane can be altered, forming a point-interval path or a line-interval energy path. 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, forming 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.

[0077] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
