[0002] Ultrasonic beauty technology is a non-invasive beauty method based on the interaction of sound wave energy and biological tissue, and it is now widely used in the field of beauty devices. Based on the principle of ultrasonic beauty, different beauty effects can be achieved by changing the distance between the ultrasonic output head of the beauty device and the user's skin. Therefore, adding a lifting mechanism to the beauty device to adjust the position of the ultrasonic output head can greatly improve the practicality of the device.

However, when adjusting the position of the ultrasonic output head in a beauty device, the required displacement is very small, and the accuracy requirement is high.

[0018] On one hand, the lifting mechanism provided by this utility model includes an actuating component comprising an actuating component and a driving component. The actuating component is inserted into a guide seat along the Z-axis direction Z, enabling the driving component to move the actuating component along the Z-axis direction Z. Additionally, an optical coupler component capable of emitting light signals along the X-axis direction X is provided, along with a blocking component capable of blocking or allowing light signals to pass through in the X-axis direction X. When the actuating component moves in the Z-axis direction Z, it drives the blocking component to move in the Z-axis direction Z, allowing the blocking component to block or allow light signals to pass through in the X-axis direction X. When the light signal is blocked by the blocking component, the driving component can operate normally, using forward or reverse driving to raise or lower the actuating component.

[0039] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present invention and not intended to limit it. Furthermore, it should be noted that, for ease of description, the accompanying drawings show only the parts relevant to the present invention, and not the entire structure.

[0040] In the description of this utility model, unless otherwise explicitly specified and limited, the terms "connected," "linked," and "fixed" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0041] In this invention, unless otherwise explicitly specified and limited, "above" or "below" the second feature can include direct contact between the first and second features, or contact between the first and second features through another feature between them. Furthermore, "above," "over," and "on top" of the second feature includes the first feature directly above or diagonally above the second feature, or simply indicates that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature includes the first feature directly below or diagonally below the second feature, or simply indicates that the first feature is at a lower horizontal level than the second feature.

[0042] In the description of this embodiment, the terms "upper," "lower," "left," and "right," etc., refer to the orientation or positional relationship shown in the accompanying drawings. They are used only for ease of description and simplification of operation, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model. In addition, the terms "first" and "second" are only used for distinction in description and have no special meaning.

[0043] On the one hand, such as Figure 1 As shown, this embodiment provides a lifting mechanism, which includes: a guide seat 1, an action component 2, an optocoupler component 4, and a blocking component 5.

[0044] like Figure 1 As shown, the aforementioned motion assembly 2 includes an actuating element 21 and a driving element 22. The actuating element 21 is, for example, a lifting rod, and the driving element 22 is a linear motor or a rotary motor. The driving element 22 is connected to the actuating element 21 via a transmission connection, and the driving element 22 can drive the actuating element 21 to move along the Z-axis direction Z. When the driving element 22 is a rotary motor, the driving element 22 and the actuating element 21 are connected via a lead screw transmission. Specifically, a lead screw is connected to the output shaft of the driving element 22, or the output shaft of the driving element 22 is provided with an external thread, and the actuating element 21 is provided with an internal thread adapted to the lead screw or the aforementioned external thread. When the output shaft of the driving element 22 rotates, the actuating element 21 can move in the Z-axis direction Z through the engagement of the threads. Furthermore, by controlling the rotation direction (forward or reverse) of the output shaft of the driving element 22, the actuating element 21 can be raised or lowered in the Z-axis direction Z.

[0045] like Figure 1As shown, the guide seat 1 is, for example, cylindrical in structure. The guide seat 1 has a sliding through hole 11 along the Z-axis direction Z, and the actuating member 21 passes through the sliding through hole 11. Furthermore, a limiting portion 211 is provided on the outer wall of the actuating member 21. This limiting portion 211 is, for example, a rectangular limiting block or a limiting post. Simultaneously, a limiting groove 111 extending along the Z-axis direction Z is provided on the inner wall of the sliding through hole 11. The limiting portion 211 is adapted to the limiting groove 111; that is, the dimensions of the limiting portion 211 in the X-axis direction X and the Y-axis direction Y are the same as the dimensions of the limiting groove 111 in the X-axis direction X and the Y-axis direction Y, respectively. The Y-axis direction Y, the X-axis direction X, and the Z-axis direction Z are arranged at an angle to each other, for example, 90°. The above settings can provide guidance for the actuator 21 and prevent it from rotating around its own axis, thereby improving transmission efficiency.

[0046] like Figure 1 As shown, the aforementioned optical coupler assembly 4 is disposed on the guide seat 1, and the two are detachably connected, for example, by bolts. The optical coupler assembly 4 is capable of emitting optical signals along the X-axis direction X, which is set at an angle to the aforementioned Z-axis direction Z, for example, 90°.

[0047] like Figure 1 As shown, the aforementioned blocking member 5 is disposed on the actuator 21. This blocking member 5 can block the light signal emitted by the optocoupler assembly 4 in the X-axis direction X. Alternatively, the blocking member 5 can allow the light signal emitted by the optocoupler assembly 4 to pass through in the X-axis direction X, so that the optocoupler assembly 4 emits an electrical signal to the drive member 22. The drive member 22 can change its operating state according to this electrical signal. In other words, the optocoupler assembly 4 can emit a light signal along the X-axis direction X. When the light signal is blocked by the blocking member 5, it indicates that the actuator 21 is in its initial state, and the drive member 22 can begin to operate, for example, driving the actuator 21 forward (rotating clockwise) to raise the actuator 21, or driving the actuator 21 backward (reversing clockwise) to lower the actuator 21; when the light signal is not blocked by the blocking member 5, the optocoupler assembly 4 emits an electrical signal to the drive member 22, causing the drive member 22 to change its operating state, that is, to change from a forward driving state or a reverse driving state to a stopped state.

[0048] Therefore, the lifting mechanism provided in this embodiment includes an action assembly 2 comprising an action member 21 and a drive member 22, with the action member 21 passing through the guide seat 1 along the Z-axis direction Z, so that the drive member 22 can drive the action member 21 to move along the Z-axis direction Z. In addition, an optical coupler assembly 4 capable of emitting light signals along the X-axis direction X is provided, and a blocking member 5 capable of blocking or allowing light signals to pass through in the X-axis direction X is provided. When the action member 21 moves in the Z-axis direction Z, it drives the blocking member 5 to move in the Z-axis direction Z, so that the blocking member 5 can block or allow light signals to pass through in the X-axis direction X. When the light signal is blocked by the blocking member 5, the driving member 22 can operate normally, causing the actuator 21 to rise or fall through forward or reverse driving. When the light signal is not blocked by the blocking member 5, the optocoupler component 4 transmits an electrical signal to the driving member 22. The driving member 22 changes its operating state according to the electrical signal, that is, it changes from the forward or reverse driving state to the stop state. In this way, the actuator 21 can move up and down in the Z-axis direction. During the above-mentioned rising and falling process of the actuator 21, the lifting and falling of the actuator 21 is achieved by the cooperation of the blocking member 5 and the optocoupler component 4. Since the optocoupler component 4 works through non-contact optical principle, it has high sensitivity and high resolution, and can accurately detect minute displacement changes, which can ensure the accuracy of the lifting and falling of the actuator 21 in the lifting mechanism.

[0049] In some embodiments, combined with Figures 1 to 4 As shown, the aforementioned optical coupling assembly 4 includes an optical signal emitting module 41 and an optical signal receiving module 42 spaced apart along the X-axis. The optical signal emitting module 41 emits optical signals along the X-axis, and the optical signal receiving module 42 receives the optical signals emitted by the optical signal emitting module 41. The optical signal receiving module 42 is coupled to the driving component 22, and this coupling includes both electrical and signal connections. The optical signal emitting module 41 is, for example, an infrared emitter, and the optical signal receiving module 42 is, for example, an infrared receiver. Of course, the optical signal emitting module 41 can also have other structures; for example, if the optical signal emitting module 41 is a laser emitter, then the optical signal receiving module 42 is a laser receiver.

[0050] The aforementioned blocking member 5 is located between the optical signal transmitting module 41 and the optical signal receiving module 42. The blocking member 5 has a first through hole 51 along the X-axis direction X, and the direction in which the optical signal emitting module 41 emits the optical signal is parallel to the opening direction of the first through hole 51. The blocking member 5 also has a blocking part 52, which, along with the first through hole 51, is arranged along the Z-axis direction Z. The blocking part 52 can block the optical signal in the X-axis direction X, while the first through hole 51 allows the optical signal to pass through in the X-axis direction X.

[0051] With the above configuration, when the actuator 21 moves in the Z-axis direction Z, it drives the blocking member 5 to move in the Z-axis direction Z, causing the position of the first through hole 51 and the blocking part 52 on the blocking member 5 to change in the Z-axis direction Z. This allows the blocking part 52 to block the light signal emitting module 41 from emitting light signals in the X-axis direction X, or to allow the light signal emitting module 41 to pass through in the X-axis direction X using the first through hole 51 (i.e., the light signal is not blocked). This configuration enables the switching between the blocking member 5 and the non-blocking state of the light signal. The structure is simple and easy to use.

[0052] In some embodiments, combined with Figures 2 to 4 As shown, the aforementioned blocking member 5 also has a second through hole 53 along the X-axis direction X. The first through hole 51 and the second through hole 53 are spaced apart along the Z-axis direction Z. The aforementioned blocking part 52 is located between the first through hole 51 and the second through hole 53. Similarly, the blocking part 52 can block the light signal in the X-axis direction X, while the first through hole 51 and the second through hole 53 can allow the light signal to pass through in the X-axis direction X. In addition, in the Z-axis direction Z, the distance between the centroids of the first through hole 51 and the blocking part 52 is less than or greater than the distance between the centroids of the second through hole 53 and the blocking part 52. In other words, the distance between the centroids of the first through hole 51 and the blocking part 52 in the Z-axis direction Z is D1, and the distance between the centroids of the second through hole 53 and the blocking part 52 in the Z-axis direction Z is D2, where D1 ≠ D2.

[0053] For example, with Figure 3Taking the shown viewpoint as an example, the first through hole 51 is located above the second through hole 53, and the blocking part 52 is between the first through hole 51 and the second through hole 53. The distance between the center position of the first through hole 51 and the center position of the blocking part 52 is D1, and the distance between the center position of the second through hole 53 and the center position of the blocking part 52 is D2. D1 < D2, for example, D1 = 2mm, D2 = 3mm. By configuring it in this way, the lifting distance of the actuator 21 of the lifting mechanism can be adjusted. Specifically, when the drive member 22 moves in the Z-axis direction Z by utilizing the cooperation of the first through hole 51 and the blocking part 52, and the operating state of the actuator 21 changes (i.e., stops running), its movement distance in the Z-axis direction Z is the distance between the center position of the first through hole 51 and the center position of the blocking part 52, i.e., D1. When the drive member 22 moves in the Z-axis direction Z by utilizing the cooperation of the second through hole 53 and the blocking part 52, and the operating state of the actuator 21 changes (i.e., stops running), its movement distance in the Z-axis direction Z is the distance between the center position of the second through hole 53 and the center position of the blocking part 52, i.e., D2. Since D1 < D2, the displacement of the actuator 21 is different in the above two operating processes, that is, the lifting distance of the actuator 21 is different. Thus, the lifting distance of the actuator 21 of the above lifting mechanism can be adjusted to meet different usage requirements and improve the practicality of the lifting mechanism.

[0054] On the other hand, this embodiment provides a beauty device output device, which includes a transducer 3 and a lifting mechanism described in any of the embodiments above. Combined with... Figures 1 to 4 As shown, the transducer 3 is disposed at the end of the actuator 21, and the transducer 3 is, for example, an ultrasonic transducer. The actuator 21 can drive the transducer 3 to move along the Z-axis direction Z. By this arrangement, the position of the transducer 3 in the Z-axis direction Z can be changed, thereby changing the distance between the transducer 3 and the user's skin. For example, raising the actuator 21 can shorten the distance between the transducer 3 and the user's skin, which can significantly reduce energy attenuation and allow more energy to be accurately delivered to the target tissue. By changing the distance between the transducer 3 and the user's skin, the energy emitted by the transducer 3 can be focused on the superficial musculo-aponeurotic system (SMAS) or the dermis, improving the practicality of the beauty device's output device.

[0055] In some embodiments, combined with Figures 5 to 12As shown, the aforementioned beauty device output device 100 also includes an adapter 6 and a swing assembly 7. One end of the adapter 6 is connected to the guide seat 1, and the other end is connected to the swing assembly 7. The adapter 6 is, for example, a plate-like structure, and its connection to the guide seat 1 and the swing assembly 7 is, for example, via bolts. The swing assembly 7 can drive the guide seat 1 to swing in the XY plane, which is the plane formed by the X-axis (X) and Y-axis (Y). The X-axis (X), Y-axis (Y), and Z-axis (Z) are arranged at angles, for example, 90°. This arrangement allows the swing assembly 7 to drive the guide seat 1 to swing in the XY plane, thereby causing the transducer component 3 of the beauty device output device 100 to swing in the XY plane, enabling the transducer component 3 to act over a larger area and improving the practicality of the beauty device output device 100.

[0056] For example, such as Figure 5 As shown, the aforementioned oscillating assembly 7 includes an oscillating element 71, a rotating shaft 72, and a power assembly 73. The oscillating element 71 includes a first end 711 and a second end 712. The first end 711 is connected to the adapter 6, for example, by bolts. The rotating shaft 72 passes through the oscillating element 71 along the Z-axis and is located between the first end 711 and the second end 712. It is easy to understand that this arrangement allows the first end 711 and the second end 712 of the oscillating element 71 to form a lever-like structure; when the second end 712 of the oscillating element 71 moves in one direction, the first end 711 of the rotating element moves in the opposite direction. Furthermore, to make power transmission smoother, a rotating shaft bearing can be added to the rotating shaft 72. The power assembly 73 drives the second end 712 to oscillate in the XY plane, causing the second end 712 to drive the first oscillation, which in turn drives the transducer 3 to oscillate in the XY plane. With the above settings, the swinging component 71 can swing in the XY plane. The structure is simple and easy to use.

[0057] In some embodiments, combined with Figures 5 to 7As shown, the aforementioned power assembly 73 includes a mounting base 731, a first magnet 732, and a second magnet 733. The mounting base 731 includes a base plate 7311 and a fixing plate 7313 mounted on the base plate 7311 via a support member 7312. The first magnet 732 is disposed on the side of the fixing plate 7313 near the base plate 7311, and the second magnet 733 is disposed on the side of the base plate 7311 near the fixing plate 7313. In the Z-axis direction Z, the first magnet 732 and the second magnet 733 are directly opposite each other; in other words, the orthographic projection of the first magnet 732 onto the base plate 7311 coincides with the orthographic projection of the second magnet 733 onto the base plate 7311. Furthermore, the first magnet 732 and the second magnet 733 have opposite polarities. For example, as... Figure 7 As shown, the N pole of the first magnet 732 is located on the right side and the S pole is located on the left side, while the N pole of the second magnet 733 is located on the left side and the S pole is located on the right side. This arrangement results in the magnetic field direction between the left ends of the first magnet 732 and the left ends of the second magnet 733 being opposite to the magnetic field direction between the right ends of the first magnet 732 and the right ends of the second magnet 733.

[0058] The second end 712 of the aforementioned swing member 71 is provided with a coil 738, which is located between the first magnet 732 and the second magnet 733.

[0059] With the above configuration, when the coil 738 located at the second end 712 of the oscillating member 71 is energized, since the coil 738 is located between the first magnet 732 and the second magnet 733, and the direction of the magnetic field formed between the left ends of the first magnet 732 and the left ends of the second magnet 733 is opposite to the direction of the magnetic field formed between the right ends of the first magnet 732 and the right ends of the second magnet 733, the direction of the Ampere force generated by the coil 738 under the action of the magnetic field formed by the left ends of the first magnet 732 and the left ends of the second magnet 733 is the same as the direction of the Ampere force generated by the coil 738 under the action of the magnetic field formed by the right ends of the first magnet 732 and the right ends of the second magnet 733. This makes the two parts of the coil 738 (i.e., the left half) the same. The resultant force on the two halves of the coil 738 pushes the coil 738 to move in a single direction (left or right). When the direction of the current inside the coil 738 is changed, the direction of the Ampere force generated by the coil 738 under the magnetic field formed by the left end of the first magnet 732 and the left end of the second magnet 733 becomes opposite to the direction of the Ampere force generated by the coil 738 under the magnetic field formed by the right end of the first magnet 732 and the right end of the second magnet 733. However, the two directions are still the same. At this time, the resultant force on the two halves of the coil 738 pushes the coil 738 to move in the opposite direction (right or left). In this way, the swinging component 71 swings in the XY plane without the need for a complex mechanical structure, which is convenient for installation and manufacturing.

[0060] It is easy to understand that more magnets could be placed in the power assembly 73 to achieve the same effect.

[0061] In some embodiments, combined with Figure 5 , Figure 8 as well as Figure 9 As shown, the aforementioned power assembly 73 includes a mounting base 731, a fourth magnet 734, a fifth magnet 735, a sixth magnet 736, and a seventh magnet 737. The mounting base 731 includes a base plate 7311 and a fixing plate 7313 mounted on the base plate 7311 via a support member 7312. The fourth magnet 734 and the fifth magnet 735 are disposed on the side of the fixing plate 7313 near the base plate 7311, and the sixth magnet 736 and the seventh magnet 737 are disposed on the side of the base plate 7311 near the fixing plate 7313. Figure 6 Taking the shown perspective as an example, the fourth magnet 734 and the fifth magnet 735 are disposed on the lower surface of the fixing plate 7313, and the sixth magnet 736 and the seventh magnet 737 are disposed on the upper surface of the substrate 7311. Furthermore, in the Z-axis direction Z, the fourth magnet 734 and the sixth magnet 736 are positioned opposite each other, as are the fifth magnet 735 and the seventh magnet 737. Simultaneously, the magnetic field generated by the fourth magnet 734 and the sixth magnet 736 is in the opposite direction to the magnetic field generated by the fifth magnet 735 and the seventh magnet 737. In other words, the polarity directions of the fourth magnet 734 and the sixth magnet 736 are the same, and the polarity directions of the fifth magnet 735 and the seventh magnet 737 are the same, but the polarity directions of the fourth magnet 734 and the fifth magnet 735 are opposite. For example, as shown... Figure 9 As shown, the N poles of the fourth magnet 734 and the sixth magnet 736 are both facing upwards and the S poles are both facing downwards, while the N poles of the fifth magnet 735 and the seventh magnet 737 are both facing downwards and the S poles are both facing upwards.

[0062] like Figure 8 As shown, the second end 712 of the aforementioned swing member 71 is provided with a coil 738, which is at least partially located between the fourth magnet 734 and the sixth magnet 736, and at least partially located between the fifth magnet 735 and the seventh magnet 737.

[0063] With the above configuration, when the coil 738 located at the second end 712 of the oscillating member 71 is energized, since the coil 738 is partially located between the fourth magnet 734 and the sixth magnet 736, and partially located between the fifth magnet 735 and the seventh magnet 737, and the magnetic field directions generated by the fourth magnet 734 and the sixth magnet 736 are opposite to those generated by the fifth magnet 735 and the seventh magnet 737, the direction of the Ampere force generated by the coil 738 under the magnetic field of the fourth magnet 734 and the sixth magnet 736 is the same as the direction of the Ampere force generated by the coil 738 under the magnetic field of the fifth magnet 735 and the seventh magnet 737, thus making the coil... The resultant force on the two parts of coil 738 pushes coil 738 to move in one direction (left or right). When the direction of the current inside coil 738 is changed, the direction of the Ampere force generated by coil 738 under the magnetic field of the fourth magnet 734 and the sixth magnet 736 becomes opposite to the direction of the Ampere force generated by coil 738 under the magnetic field of the fifth magnet 735 and the seventh magnet 737, but the two directions are still the same. At this time, the resultant force on the two parts of coil 738 pushes coil 738 to move in the opposite direction (right or left). In this way, the swinging component 71 swings in the XY plane without the need for a complex mechanical structure, which is convenient for installation and manufacturing.

[0064] In some embodiments, combined with Figures 5 to 7 As shown, the aforementioned swing assembly 7 also includes a third magnet 74 disposed on the side of the fixed plate 7313 facing away from the substrate 7311 and a Hall sensor assembly 77. The third magnet 74 extends along the Y-axis direction Y. The Hall sensor assembly 77 is disposed on the aforementioned swing assembly 71. The Hall sensor assembly 77 includes a Hall circuit board 771 extending along the X-axis direction X and a Hall sensor 772 disposed on the Hall circuit board 771. In the X-axis direction X, the centroid of the Hall sensor 772 is directly opposite the centroid of the third magnet 74. In other words, in the X-axis direction X, the Hall sensor 772 is positioned directly opposite the middle position of the third magnet 74, so that the distance between the two ends of the Hall sensor 772 and the third magnet 74 is the same.

[0065] Through the above settings, the swing position of the oscillating member 71 can be determined by the cooperation of the Hall sensor component 77 and the third magnet 74, thereby enabling control of the oscillation frequency of the oscillating member 71. For example, when the Hall sensor component 77 is positioned directly opposite the middle of the third magnet 74, i.e., the oscillating member 71 is parallel to the X-axis, the power supply to the coil 738 on the oscillating member 71 is disconnected, causing the oscillating member 71 to stop oscillating for a preset time (e.g., 90ms to 120ms). After the preset time ends, the power supply to the coil 738 on the oscillating member 71 is resumed, causing the oscillating member 71 to oscillate under the action of the power component 73. Simultaneously, by adjusting the length of the preset time, the oscillation frequency of the oscillating member 71 can be controlled to meet different usage requirements, improving the practicality of the aforementioned beauty instrument output mechanism / beauty instrument output device 100.

[0066] Of course, other settings can also be used to achieve the above effect.

[0067] In some embodiments, combined with Figure 5 , Figure 8 as well as Figure 9 As shown, the aforementioned swing assembly 7 also includes an eighth magnet 75 and a ninth magnet 76 disposed on the side of the fixed plate 7313 facing away from the base plate 7311, so as to... Figure 6 Taking the shown perspective as an example, the eighth magnet 75 and the ninth magnet 76 are disposed on the upper surface of the fixing plate 7313. The eighth magnet 75 and the ninth magnet 76 are arranged at intervals along the Y-axis direction Y, and the polarity directions of the eighth magnet 75 and the ninth magnet 76 are arranged in opposite directions, for example, as shown. Figure 7 As shown, the eighth magnet 75 has its N pole facing upwards and its S pole facing downwards, while the ninth magnet 76 has its N pole facing downwards and its S pole facing upwards. Here, the Y-axis (Y), X-axis (X), and Z-axis (Z) are arranged at an angle to each other, for example, 90°.

[0068] The aforementioned oscillating assembly 7 also includes a Hall effect sensor 77 disposed on the aforementioned oscillating member 71. The Hall effect sensor 77 includes a Hall effect circuit board 771 extending along the X-axis direction X and a Hall effect sensor 772 disposed on the Hall effect circuit board 771. The Hall effect sensor 772 is located between the eighth magnet 75 and the ninth magnet 76, and in the Y-axis direction Y, the distance between the Hall effect sensor 772 and the eighth magnet 75 is equal to the distance between the Hall effect sensor 772 and the ninth magnet 76 75.

[0069] Through the above settings, the swing position of the oscillating member 71 can be determined by the cooperation of the Hall sensor component 77 with the eighth magnet 75 and the ninth magnet 76, thereby enabling control of the oscillation frequency of the oscillating member 71. For example, when the Hall sensor component 77 is located precisely between the eighth magnet 75 and the ninth magnet 76, i.e., the oscillating member 71 is parallel to the X-axis, the power supply to the coil 738 on the oscillating member 71 is disconnected, causing the oscillating member 71 to stop oscillating for a preset time. After the preset time ends, the power supply to the coil 738 on the oscillating member 71 is resumed, causing the oscillating member 71 to oscillate under the action of the power component 73. Simultaneously, by adjusting the length of the preset time, the oscillation frequency of the oscillating member 71 can be controlled to meet different usage needs, improving the practicality of the aforementioned beauty device output device 100.

[0070] On the other hand, combining Figures 13 to 15 As shown, this embodiment provides a beauty device 1000, which includes a housing 8, a power supply 9, a control module 10, and a beauty device output device 100 described in any of the above embodiments. The beauty device output device 100 is electrically connected to the power supply 9, and both are disposed inside the housing 8. The power supply 9 supplies power to the drive unit 22 in the beauty device output device 100. The housing 8 has an output port 81, and the transducer assembly 3 is positioned opposite the output port 81.

[0071] like Figure 15 As shown, the control module 10 is disposed inside the housing 8. This control module 10 is coupled to the beauty instrument output device 100 and is used to control the operating state of the beauty instrument output device 100. For example, the control module 10 can switch the lifting distance of the lifting mechanism and the oscillation frequency of the oscillating assembly 7 in the beauty instrument output device 100. Those skilled in the art can make specific settings for the control module 10 according to actual usage requirements; no further limitations are made here.
