Description

Technical Field

[0001] This application relates to the field of skin care technology, and more particularly to a skin care device and a skin care device kit. Background Technology

[0002] Ultrasonic skincare, such as microfocused ultrasound (MFU) beauty technology, is a common skincare method in the medical aesthetics industry. During the treatment, the ultrasonic transducer inside the ultrasonic skincare device generates focused ultrasound waves to create treatment points under the skin, thereby achieving anti-aging and lifting effects.

[0003] In related technologies, some ultrasonic skin care devices are equipped with a drive motor to drive the ultrasonic transducer to rotate around an axis, so that the focal point of the ultrasonic transducer makes circular motion in a plane, thereby achieving skin care for a large area.

[0004] However, during the production of ultrasonic skin care devices, it is necessary to test or calibrate them. For example, the electroacoustic conversion efficiency of different ultrasonic transducers is not consistent, so the power of the ultrasonic transducers of the ultrasonic skin care device needs to be calibrated during the assembly process before leaving the factory; and the focal depth of the ultrasonic transducers in different modes also needs to be calibrated.

[0005] However, because the focal point of an ultrasonic transducer can move, it is not easy for testing equipment to accurately test or calibrate the ultrasonic transducer from the focal point side. Utility Model Content

[0025] The skin care device further includes a second drive assembly, which is connected to the drive shaft assembly via the mounting port. The second drive assembly drives the drive shaft to move relative to the coupling along the first axis, thereby causing the transducer assembly to move along the first axis to move closer to or further away from the sound emission area; and / or

[0071] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the protection scope of this application.

[0072] Please refer to Figure 1 and Figure 2 This application provides a skin care device, including a housing 100, a mounting bracket 200, a drive shaft assembly 300, a transducer assembly 400, and a first drive assembly 500.

[0073] The housing 100 has a sound-emitting area 11. A mounting bracket 200 is disposed within the housing 100. A drive shaft assembly 300 is at least partially rotatably mounted within the mounting bracket 200. A transducer assembly 400 is mounted on the drive shaft assembly 300, and the ultrasonic wave focal point of the transducer assembly 400 passes through the sound-emitting area 11 for penetration into the skin to be treated. A first drive assembly 500 is drively connected to the drive shaft assembly 300, and the first drive assembly 500 is used to drive the drive shaft assembly 300 to rotate, thereby driving the transducer assembly 400 to rotate.

[0074] Furthermore, when the sound-emitting area 11 approaches or adheres to the skin to be treated, i.e. when the skin care device is in operation, the first drive component 500 can drive the transducer component 400 to rotate through the transmission shaft component 300, so that the ultrasonic focus of the transducer component 400 can make a circular motion at the same subcutaneous depth of the skin to be treated, thereby achieving the care of a large area of ​​the skin to be treated.

[0075] In related technologies, to ensure the reliability of the transducer assembly 400 during the use of skin care equipment, it is necessary to test and calibrate the transducer assembly 400 during the production process of the skin care equipment. However, during the production process of skin care equipment, since the rotation angle of the drive shaft assembly 300 relative to the mounting bracket 200 is uncertain, the specific orientation (or position) of the transducer assembly 400 is also uncertain, making it difficult for external testing equipment 91 to accurately test and calibrate the ultrasonic transducer from the focal point of the ultrasonic transducer.

[0076] The inventors discovered that although the first drive assembly 500 can pause the drive shaft assembly 300 at a certain angle, thereby pausing the transducer assembly 400 at a certain angle, so that the external testing equipment 91 can test and calibrate the ultrasonic transducer from the sound output side of the ultrasonic transducer of the transducer assembly 400, the first drive assembly 500 makes the angle at which the drive shaft assembly 300 stops uncontrollable, resulting in the pausing angle of the transducer assembly 400 being uncontrollable, making it difficult to mass-produce.

[0077] The inventors also discovered through research that, in one solution, an internal detection device (e.g., a sensor) can be installed inside the skin care device to detect the rotation of the drive shaft assembly 300 and the transducer assembly 400, so that the drive shaft assembly 300 and the transducer assembly 400 can be fixed after rotating to a preset angle, which is convenient for mass production; however, this solution is more expensive because it requires an internal detection device to be installed in each skin care device.

[0078] Based on this, please continue to refer to Figure 3 and Figure 4In this embodiment, the mounting bracket 200 is provided with a detection through hole 231, and the drive shaft assembly 300 is provided with a first positioning structure 321 located within the mounting bracket 200. When the drive shaft assembly 300 rotates to a preset angle, the first positioning structure 321 faces the detection through hole 231, so that the external detection device 91 can detect the first positioning structure 321 through the detection through hole 231.

[0079] Then, the external testing equipment 91 can detect the first positioning structure 321 through the detection through hole 231, thereby determining whether the drive shaft assembly 300 has rotated to the preset angle, and thus determining whether the transducer assembly 400 connected to the drive shaft assembly 300 has rotated to the appropriate angle, so as to facilitate subsequent testing or calibration.

[0080] For example, the detection device 91 may include a first detection component 911 and a second detection component 912. The first detection component 911 is used to detect the first positioning structure 321 through the detection through hole 231 to detect the rotation angle of the drive shaft assembly 300. The second detection component 912 is used to detect the parameter information of the transducer assembly 400.

[0081] The parameter information may include power information, such as power per liter. Of course, the parameter information may also include the form and position tolerances of the transducer assembly 400, focal length information, etc., but this application embodiment does not limit this.

[0082] It is understandable that adding a sensor inside the skin care device to detect the rotation angle of the drive shaft assembly 300 would allow the device to monitor the rotation angles of both the drive shaft assembly 300 and the transducer assembly 400. However, during actual operation, the first drive assembly 500 only needs to drive the transducer assembly 400 to rotate a preset number of revolutions via the drive shaft assembly 300 to complete the skin care treatment. The initial angle at which the transducer assembly 400 begins to rotate has little impact on the skin care effect. Therefore, this sensor has little effect on the skin care effect but increases the cost of each device. In contrast, this embodiment only requires an external testing device 91 to test a large number of skin care devices, making it more suitable for mass production of skin care devices.

[0083] It is also understood that the preset angle can be any angle during the rotation of the drive shaft assembly 300, as long as the drive shaft assembly 300 is rotated to the preset angle so that the second detection component 912 can detect the transducer assembly 400. This application embodiment does not limit this.

[0084] In some embodiments, the first positioning structure 321 includes a first positioning hole.

[0085] For example, when the drive shaft assembly 300 rotates to a preset angle, the detection device 91 can pass through the detection through hole 231 and insert into the first positioning hole via the first detection component 911. Thus, by checking whether the first detection component 911 is inserted into the first positioning hole, it can be determined whether the drive shaft assembly 300 has rotated to the preset angle, and correspondingly, it can be determined whether the transducer assembly 400 has also rotated to the appropriate angle for detection.

[0086] It is also understandable that when the drive shaft assembly 300 rotates to a preset angle, a rotational damping can be applied to the drive shaft assembly 300 by the insertion of the first detection component 911 into the first positioning hole, so as to keep the drive shaft assembly 300 at the preset angle, thereby facilitating the detection of the second detection component 912 in the subsequent process.

[0087] The first detection component 911 may include a probe for passing through the detection through-hole 231.

[0088] For example, the first detection component 911 may include an elastic probe. In the actual detection process, the elastic probe can first pass through the detection through-hole 231 and abut against the drive shaft assembly 300. When the drive shaft assembly 300 has not rotated to a preset angle, the first detection component 911 abuts against the peripheral surface of the drive shaft assembly 300; when the drive shaft assembly 300 has not rotated to the preset angle, the elastic probe is driven by its own elastic force to insert into the first positioning hole.

[0089] In some implementations, the first positioning hole can be a blind hole.

[0090] It is understandable that if the first positioning hole is a through hole, the structure of the first positioning hole penetrating the drive shaft assembly 300 may reduce the strength of the drive shaft assembly 300. Therefore, during the process of the first drive assembly 500 driving the drive shaft assembly 300 to rotate, the drive shaft assembly 300 may be bent, deformed or even broken.

[0091] Of course, in some other implementations, the first positioning hole may also be a through hole, and this application embodiment does not limit this.

[0092] In some embodiments, the diameter of the first positioning hole is less than or equal to the diameter of the detection through hole 231.

[0093] It is understandable that the outer diameter of the portion of the first detection component 911 passing through the detection through hole 231 should be smaller than the diameter of the detection through hole 231. Therefore, the diameter of the first positioning hole should be smaller than or equal to the diameter of the detection through hole 231 so that the portion of the first detection component 911 passing through the detection through hole 231 can be inserted for detection. At the same time, it can avoid the opening area of ​​the first positioning hole being too large, which would result in insufficient strength of the drive shaft assembly 300.

[0094] Of course, in some other embodiments, the diameter of the first positioning hole may also be larger than the diameter of the detection through hole 231, and this application embodiment does not limit this.

[0095] It is also understood that in some other embodiments, the first positioning structure 321 may also include an indicator, and the corresponding first detection component 911 can identify the indicator through the detection through hole 231; or, the first positioning structure 321 may also include some protruding structures, which are not limited in this application embodiment.

[0096] The above are some examples of the first positioning structure 321 in the embodiments of this application. The following will continue to introduce other structures of the transmission shaft assembly 300.

[0097] Please continue to refer to this. Figure 5 and Figure 6 The drive shaft assembly 300 is provided with a non-cylindrical first clamping part 312. The first clamping part 312 is used for clamping by an external clamping device 92 to restrict the rotation of the drive shaft assembly 300 relative to the mounting bracket 200.

[0098] So, after the testing device 91 detects that the drive shaft assembly 300 has rotated to a preset angle, the clamping device 92 can automatically clamp the first clamping part 312, or the operator can manually operate the clamping device 92 to clamp the first clamping part 312, thereby fixing the drive shaft assembly 300 to prevent the drive shaft assembly 300 from rotating unexpectedly during subsequent testing and affecting the test results.

[0099] It is also understandable that, on the one hand, compared to the cylindrical first clamping part 312, the non-cylindrical structure can make the clamping of external devices more stable and reliable.

[0100] For example, the first clamping part 312 can be prism-shaped, elliptical, or any other irregular columnar structure, etc., and the embodiments of this application do not limit this.

[0101] It is also understood that the clamping device 92 can be used to clamp only the drive shaft assembly 300, or it can be used to clamp the drive shaft assembly 300 together with other parts of the skin care device. This application embodiment does not limit this.

[0102] Please continue to refer to this. Figure 7 For example, the mounting bracket 200 is provided with a second clamping part 232, which and the first clamping part 312 are used together to be clamped by an external clamping device 92 to restrict the rotation of the drive shaft assembly 300 relative to the mounting bracket 200.

[0103] Thus, by having the second clamping part 232 and the first clamping part 312 jointly clamped by the external clamping device 92, the position of the clamping device 92 can be determined by using the mounting bracket 200 as a position reference, thereby ensuring that the clamping device 92 clamps and fixes the drive shaft assembly 300 at a suitable angle from a suitable position.

[0104] In some embodiments, the first clamping part 312 includes at least one first clamping surface 313, and the second clamping part 232 includes a second clamping surface 233. When the drive shaft assembly 300 rotates to a preset angle, at least one first clamping surface 313 and the second clamping surface 233 are arranged parallel to each other or at an angle to each other for clamping by the clamping device 92.

[0105] For example, one clamping arm 921 of the clamping device 92 may abut against the first clamping surface 313, and the other clamping arm 921 may be fixed to the second clamping surface 233, thereby clamping and fixing the second clamping part 232 and the first clamping part 312 together through the two clamping arms 921.

[0106] In some embodiments, the first clamping part 312 includes at least one first clamping surface 313, and the second clamping part 232 includes a second clamping surface 233. When the drive shaft assembly 300 is rotated to a preset angle, at least one first clamping surface 313 is located on the side of the drive shaft assembly 300 away from the second clamping surface 233, so as to be clamped by the clamping device 92.

[0107] Furthermore, the two clamping arms 921 of the clamping device 92 can respectively abut against the first clamping surface 313 and the second clamping surface 233 to clamp and fix the second clamping part 232 and the first clamping part 312 together.

[0108] In some embodiments, the first clamping part 312 includes at least two first clamping surfaces 313, which are arranged circumferentially around the drive shaft assembly 300.

[0109] Therefore, the clamping device 92 can selectively cooperate with different numbers and / or different positions of the first clamping surfaces 313 according to actual needs.

[0110] When the clamping device 92 cooperates with at least two first clamping surfaces 313 to clamp the drive shaft assembly 300, the cooperation area between the clamping device 92 and the first clamping part 312 can be increased, thereby improving the stability and reliability of the clamping by the clamping device 92.

[0111] For example, combining Figure 7 and Figure 8 One of the clamping arms 921 of the clamping device 92 may be provided with a clamping notch 922. When the clamping device 92 clamps the first clamping part 312, the inner surface of the clamping notch 922 may abut against at least two first clamping surfaces 313.

[0112] In some embodiments, the shape of the clamping notch 922 is adapted to the first clamping portion 312. For example, the clamping notch 922 is a rectangular notch, and the first clamping portion 312 is prismatic and has four first clamping surfaces 313.

[0113] Therefore, when the clamping device 92 clamps the first clamping part 312, even if there is a small deviation between the actual angle of the transmission shaft assembly 300 and the preset angle, the inner surface of the clamping notch 922 can still cooperate with the three corresponding first clamping surfaces 313 to correct the deviation, so that the transmission shaft assembly 300 is pushed by the clamping arm 921 to rotate and be fixed at the preset angle.

[0114] In some embodiments, the first clamping surface 313 is a plane.

[0115] It is understandable that, compared to a curved structure, a planar first clamping surface 313 can improve the slippage between the first clamping surface 313 and the clamping device 92, thereby improving the stability and reliability of the drive shaft assembly 300 when clamped. Of course, in some other embodiments, the first clamping surface 313 may also be curved, and this application embodiment does not limit this.

[0116] In some embodiments, the second clamping surface 233 includes a second clamping surface 233, which is a plane.

[0117] It is understandable that, compared to a curved structure, a planar second clamping surface 233 can improve the slippage between the second clamping surface 233 and the clamping device 92, thereby improving the stability and reliability of the drive shaft assembly 300 when clamped. Of course, in some other embodiments, the second clamping surface 233 may also be curved, and this application embodiment does not limit this.

[0118] In some embodiments, the second clamping part 232 is provided with a clamping groove for a clamping arm 921 of the clamping device 92 to clamp onto the inner surface of the clamping groove.

[0119] Furthermore, by embedding one of the clamping arms 921 of the clamping device 92 into the clamping groove, the clamping arm 921 can achieve a better positioning effect, thereby improving the stability and reliability of clamping.

[0120] In some embodiments, the bottom wall of the clamping groove may form a second clamping surface 233.

[0121] Please continue to refer to this. Figure 9In some embodiments, the mounting bracket 200 is provided with a mounting opening 234, which is located on one side of the drive shaft assembly 300 in the circumferential direction. The first clamping part 312 is located on the side of the mounting bracket 200 opposite to the mounting opening 234, so that one clamping arm 921 of the clamping device 92 abuts against the first clamping part 312 via the mounting opening 234, and the other clamping arm 921 abuts against the second clamping part 232, thereby giving the mounting bracket 200 and the drive shaft assembly 300 the advantage of easy clamping.

[0122] For example, the mounting bracket 200 may include a first horizontal plate 21, a second horizontal plate 22, and a surrounding plate 23. The first horizontal plate 21 and the second horizontal plate 22 are spaced apart along the axis of the drive shaft assembly 300 (i.e., the first axis L1 hereinafter). The surrounding plate 23 is arranged circumferentially around the drive shaft assembly 300 and is also connected to the first horizontal plate 21 and the second horizontal plate 22, such that the drive shaft assembly 300 is at least partially rotatably mounted within the mounting bracket 200.

[0123] Correspondingly, mounting openings 234 are formed at both ends of the enclosure 23 around the drive shaft assembly 300 in the circumferential direction. Detection through holes 231 can be provided in the enclosure 23.

[0124] Furthermore, when the mounting bracket 200 includes a second clamping part 232, the second clamping part 232 may also be provided on the enclosure 23.

[0125] The technical solution of the embodiments of this application will be introduced below in conjunction with the structure of the driven drive shaft assembly 300.

[0126] Please continue to refer to this. Figure 10 In some embodiments, the first drive assembly 500 includes a first motor, the drive shaft assembly 300 includes a drive shaft 31 and a coupling 32, the transducer assembly 400 is mounted on the drive shaft 31, and the coupling 32 is connected to the output shaft of the first motor and the drive shaft 31 respectively, so that the first motor can drive the drive shaft 31 to rotate, thereby driving the transducer assembly 400 to rotate around the first axis L1.

[0127] The first axis L1 can pass through the sound-emitting area 11. For example, the first axis L1 is approximately perpendicular to the sound-emitting area 11. Furthermore, when the sound-emitting area 11 is close to or in contact with the skin to be treated, i.e. when the skin care device is in operation, the first drive assembly 500 can drive the transducer assembly 400 to rotate via the transmission shaft assembly 300, so that the ultrasonic focus of the transducer assembly 400 can make a circular motion at the same subcutaneous depth of the skin to be treated, thereby achieving treatment of a large area of ​​the skin to be treated.

[0128] Correspondingly, at least one of the coupling 32 and the drive shaft 31 may be provided with a first positioning structure 321.

[0129] In actual assembly, when only one of the coupling 32 and the drive shaft 31 is provided with the first positioning structure 321, the number of structures such as the first positioning hole on the drive shaft assembly 300 can be reduced. This reduces the number of machining steps for the drive shaft assembly 300 and improves its structural strength. When both the coupling 32 and the drive shaft 31 are provided with the first positioning structure 321, the coupling 32 or the drive shaft 31 can be selectively inspected according to actual needs, or both can be inspected simultaneously to improve the accuracy and reliability of the inspection results. This application does not limit this approach.

[0130] Please continue to refer to this. Figure 11 In some embodiments, the ultrasonic focus of the transducer assembly 400 is misaligned with the first axis L1, so that as the transducer assembly 400 rotates around the first axis L1 along with the drive shaft assembly 300, the ultrasonic focus of the transducer assembly 400 can rotate around the first axis L1.

[0131] For example, the transducer assembly 400 includes an ultrasonic transducer, the axis L2 of which is inclined to the first axis L1, so that the ultrasonic focus of the transducer assembly 400 is misaligned with the first axis L1.

[0132] Alternatively, the transducer assembly 400 may include an ultrasonic transducer, which is eccentrically positioned relative to the first axis L1, such that the ultrasonic focal point of the transducer assembly 400 is misaligned with the first axis L1. This embodiment of the application does not limit this.

[0133] In some embodiments, the skin care device further includes a second drive assembly 600, which is connected to the drive shaft assembly 300. The second drive assembly 600 is used to drive the drive shaft 31 to move relative to the coupling 32 along the first axis L1, thereby causing the transducer assembly 400 to move along the first axis L1 to move closer to or away from the sound output area 11.

[0134] Therefore, on the one hand, by moving the drive shaft assembly 300 along the first axis L1, the transducer assembly 400 can be driven to move closer to or further away from the sound-emitting area 11. Thus, when the sound-emitting area 11 approaches or adheres to the skin to be treated (i.e., when the skin care device is working), the ultrasonic focus of the transducer assembly 400 can be adjusted to be at different depths within the skin to be treated, thereby providing ultrasonic skin care for skin at different subcutaneous depths. On the other hand, by rotating the drive shaft assembly 300 around the first axis L1, the ultrasonic focus of the transducer assembly 400 can be driven to rotate around the first axis L1, allowing the ultrasonic focus of the transducer assembly 400 to act on different locations at the same depth within the skin to be treated, thus providing ultrasonic skin care for skin at the same subcutaneous depth. Therefore, in this embodiment, the position of the ultrasonic focus of the transducer assembly 400 can be adjusted via the drive shaft assembly 300 to achieve ultrasonic skin care for different parts at the same depth and different depths within the skin to be treated.

[0135] Please combine Figure 9 and Figure 10 In some embodiments, the second drive assembly 600 is connected to the drive shaft assembly 300 via the mounting port 234 to drive the drive shaft 31 to move relative to the coupling 32 along the first axis L1.

[0136] Therefore, the mounting port 234 can also be reused for the clamping device 92 to clamp the drive shaft assembly 300 and the second drive assembly 600 to drive the drive shaft assembly 300, so that the mounting bracket 200 does not need to have a separate opening for the clamping device 92 to clamp the drive shaft assembly 300, so that the structure of the mounting bracket 200 can be simpler and the strength can be higher.

[0137] In some embodiments, the coupling 32 is provided with a transmission hole 322, and the end of the transmission shaft 31 near the coupling 32 is a transmission end 314. The transmission end 314 has a non-cylindrical structure and is installed in the transmission hole 322, so that the transmission shaft 31 can move relative to the coupling 32 along the first axis L1 but cannot rotate around the first axis L1. Thus, the first drive assembly 500 can drive the transmission shaft 31 to rotate around the first axis L1 through the coupling 32, while the second drive assembly 600 can drive the transmission shaft assembly 300 to move relative to the coupling 32 along the first axis L1.

[0138] In some embodiments, the transmission end 314 forms a first clamping portion 312.

[0139] Furthermore, the transmission end 314 is reused for the transmission between the coupling 32 and the transmission shaft 31, as well as for clamping by the clamping device 92, so that the transmission shaft 31 does not need to be separately machined as a first clamping part 312, which ultimately makes the manufacturing of the transmission shaft 31 simpler.

[0140] In some embodiments, a drive position 315 is provided on the circumferential side of the drive shaft 31, and the drive position 315 is located between the transducer assembly 400 and the first drive assembly 500. For example, the drive position 315 is located at the middle of the drive shaft 31. The second drive assembly 600 and the drive shaft 31 form a drive connection at the drive position 315, so that the second drive assembly 600 can drive the drive shaft 31 to move along the first axis L1, and the first drive assembly 500 allows the drive shaft 31 to rotate about the first axis L1.

[0141] For example, the second drive assembly 600 includes a pusher 61, which is connected to the drive position 315 in a separable manner through magnetic connection, negative pressure adsorption, clutch assembly, etc., so that the pusher 61 can move along the first axis L1 to push the drive shaft 31 to move along the first axis L1, and the drive shaft 31 can also rotate relative to the pusher 61 about the first axis L1.

[0142] Of course, the pusher 61 can also cooperate with the drive position 315 in other ways.

[0143] For example, the drive position 315 includes an annular transmission groove on the outer periphery of the transmission shaft 31. The pusher 61 is partially rotatably engaged within the transmission groove relative to the transmission shaft 31 to form a transmission connection. Thus, since the pusher 61 is partially engaged within the transmission groove, when the pusher 61 moves along the first axis L1, it can push the groove wall of the transmission groove, causing the transmission shaft 31 to move along the first axis L1. Simultaneously, since the pusher 61 is rotatably disposed relative to the transmission shaft 31, the transmission shaft 31 can also rotate around the first axis L1, allowing the pusher 61 to engage at different circumferential positions in the transmission groove, thereby preventing interference between the rotation of the pusher 61 and the transmission shaft 31.

[0144] In some embodiments, the second drive assembly 600 further includes a second motor 62 for driving the drive shaft 31 to move along the axial direction (i.e., the direction of the first axis L1) via the pusher 61.

[0145] In some embodiments, the second drive assembly 600 further includes a lead screw module 63, which includes a lead screw and a lead screw nut screwed onto the lead screw. The lead screw nut is connected to the pusher 61, and the lead screw is drively connected to the output shaft of the second motor 62. Thus, the lead screw module 63 can improve the accuracy of the second motor 62 in driving the pusher 61.

[0146] It should be noted that the lead screw nut and the pusher 61 can be integrally formed or separately formed, and this application embodiment does not limit this.

[0147] In some embodiments, the second drive assembly 600 further includes a gear reduction module 64, through which the output shaft of the second motor 62 and the lead screw are connected. Therefore, because the gear reduction module 64 and the lead screw module 63 are added to the transmission chain between the second motor 62 and the transmission shaft 31, the accuracy of the second motor 62 driving the transmission shaft 31 can be improved twice, thereby improving the adjustment accuracy of the transducer assembly 400.

[0148] In some embodiments, the lead screw module 63 is fixedly mounted to the mounting bracket 200, the gear reduction module 64 is fixedly mounted to the lead screw module 63, and the second motor 62 is fixedly mounted to the gear reduction module 64. Therefore, in the actual assembly process, the second motor 62, the lead screw module 63, and the gear reduction module can be installed as a single unit on the mounting bracket 200 to improve the assembly efficiency of the skin care device.

[0149] In some embodiments, the second drive assembly 600 further includes a second sensor for detecting the position information of the lead screw nut. By using the position information of the lead screw nut detected by the second sensor as feedback, the second motor 62 can drive the drive shaft 31 to move more accurately, thereby improving the adjustment accuracy of the transducer assembly 400.

[0150] Please continue to refer to this. Figure 12 In some embodiments, the drive shaft 31 is provided with a second positioning structure 311. Therefore, during the assembly of the drive shaft 31 and the transducer assembly 400, the angle of the drive shaft 31 can be determined by the second positioning structure 311. Then, using the second positioning structure 311 as a reference, the transducer assembly 400 can be assembled to the drive shaft 31 at a suitable angle or orientation. Furthermore, during subsequent testing, if the angle of the drive shaft 31 is accurate, the angle of the transducer assembly 400 will also be accurate.

[0151] In some embodiments, the mounting bracket 200 is provided with a viewing window 235. When the drive shaft assembly 300 is rotated to a preset angle, the viewing window 235 faces the second positioning structure 311.

[0152] Therefore, during the production of skin care equipment, the detection equipment 91 can detect the first positioning structure 321 through the detection through hole 231 to determine whether the transmission shaft assembly 300 has rotated to the preset angle, and the user can observe the second positioning structure 311 through the viewing window 235 to determine whether the transmission shaft assembly 300 has rotated to the preset angle, thus making the skin care equipment applicable to more detection scenarios.

[0153] In some embodiments, the viewing window 235 is disposed through the second clamping part 232. This allows the user to directly observe the second positioning structure 311 through the viewing window 235 when clamping the mounting bracket 200, and also makes the structure on the mounting bracket 200 more compact, so as to avoid the need to reserve too much space inside the housing to accommodate the second clamping part 232 and the viewing window 235 respectively.

[0154] In some embodiments, the second positioning structure 311 is disposed on the drive shaft 31, and the second positioning structure 311 is disposed on the coupling 32.

[0155] In some embodiments, the skin care device also includes a circuit board 800, which is electrically connected to the first drive assembly 500. The circuit board 800 is also provided with a first electrical connection part 81, which is used to electrically connect to a detection device 91 so that the detection device 91 can control the first drive assembly 500.

[0156] For example, the testing device 91 is provided with a second electrical connection part 913, which can form an electrical connection with the first electrical connection part 81 by means of contact, insertion, clamping, etc.

[0157] Therefore, during the production process of skin care equipment, after the first detection component 911 of the detection device 91 detects the first positioning structure 321, the detection device 91 can control the first drive component 500 to stop working through the first electrical connection part 81 so that the drive shaft assembly 300 stops at a preset angle. Then, depending on the actual needs, the drive shaft assembly 300 can be clamped or not. Finally, the transducer assembly 400 is clamped by the second detection component 912 of the detection device 91.

[0158] The first electrical connection part 81 may include conductive contacts, conductive springs, sockets, etc., but the embodiments of this application do not limit this.

[0159] The technical solutions of the embodiments of this application will now be described in conjunction with the cooperation structure between the drive shaft 31 and the second drive assembly 600.

[0160] like Figure 11 As shown, in some embodiments, the skin care device further includes a medium housing 700, which is at least partially disposed within the outer casing 100. A medium chamber 71 is formed between the medium housing 700 and the outer casing 100, and a transducer assembly 400 is disposed within the medium chamber 71. The medium chamber 71 stores the ultrasonic wave transmission medium. Therefore, by using the ultrasonic wave transmission medium, the loss of ultrasonic waves generated by the transducer assembly 400 during their penetration into the skin to be treated can be reduced, thereby improving the skin care effect.

[0161] It is understood that, on the one hand, the outer shell 100 may form part of the inner wall of the medium chamber 71, or the outer shell 100 may not form the inner wall of the medium chamber 71, and the embodiments of this application do not limit this; on the other hand, the medium shell 700 and the outer shell 100 may be integrally formed or separately formed, and the embodiments of this application do not limit this either.

[0162] In some embodiments, the drive shaft assembly 300 passes through the medium housing 700.

[0163] For example, as mentioned above, the drive shaft assembly 300 includes a coupling 32 and a drive shaft 31. One end of the drive shaft 31 may extend into the medium chamber 71, and the transducer assembly 400 may be mounted on the end of the drive shaft 31 that extends into the medium chamber 71. The portion of the drive shaft 31 located outside the medium housing 700 is rotatably mounted on the mounting bracket 200 for transmission connection with the first drive assembly 500.

[0164] Correspondingly, when the skin care device also includes a second drive assembly 600, the second drive assembly 600 may also be connected to the portion of the drive shaft 31 located outside the media housing 700.

[0165] In some embodiments, the mounting bracket 200 may be mounted on the media housing 700.

[0166] This application embodiment also provides a skin care device kit, including a skin care device and a detection device 91. The skin care device is the skin care device described above. The detection device 91 includes a first detection component 911 and a second detection component 912. The first detection component 911 is used to detect the first positioning structure 321 through the detection through hole 231 to detect the rotation angle of the drive shaft assembly 300. The second detection component 912 is used to detect the parameter information of the transducer assembly 400.

[0167] In some embodiments, the skin care device kit also includes a clamping device 92 for clamping the drive shaft assembly 300 and the mounting bracket 200 to limit the rotation of the drive shaft assembly 300.

[0168] Therefore, a testing procedure for skin care devices can be as follows:

[0169] First, the first detection component 911 of the external detection device 91 can detect the first positioning structure 321 through the detection through hole 231, thereby determining whether the drive shaft assembly 300 has rotated to a preset angle, and thus determining whether the transducer assembly 400 connected to the drive shaft assembly 300 has rotated to a suitable angle.

[0170] Then, the first clamping part 312 is automatically clamped by the clamping device 92, or the operator manually operates the clamping device 92 to clamp the first clamping part 312, thereby fixing the drive shaft assembly 300.

[0171] Finally, the second detection component 912 of the detection device 91 detects the transducer assembly 400.

[0172] It is understandable that adding a sensor inside the skin care device to detect the rotation angle of the drive shaft assembly 300 would allow the device to monitor the rotation angles of both the drive shaft assembly 300 and the transducer assembly 400 in real time. However, during actual operation, the first drive assembly 500 only needs to drive the transducer assembly 400 to rotate a preset number of times via the drive shaft assembly 300 to complete the skin care treatment. The initial angle at which the transducer assembly 400 begins to rotate has little impact on the skin care effect. Therefore, this sensor has little effect on the skin care effect but increases the cost of each device. In contrast, this embodiment only requires an external testing device 91 to test a large number of skin care devices, making it more suitable for mass production of skin care devices.

[0173] In some embodiments, the specific structures of the detection device 91 and the clamping device 92 can be referred to the detection device 91 and clamping device 92 described above, respectively, and will not be repeated here in the embodiments of this application.
