Description

Technical Field

[0001] This application relates to the field of skin care technology, and more particularly to a skin care device. 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] Specifically, ultrasonic skin care devices surpass the depth limitations of traditional non-surgical equipment, penetrating deep into the SMAS fascia layer. Ultrasonic energy concentrates at the skin care points, generating high temperatures that cause the target tissues in the lower layers of the skin to contract under these high temperatures, stimulating collagen regeneration. This results in anti-aging, wrinkle reduction, firming, lifting, and contouring effects. For example, the energy waves generated by the ultrasonic transducer act directly on the fascia layer, causing it to contract.

[0004] In related technologies, ultrasonic skin care devices include a medium chamber containing an ultrasonic transducer fluid. The ultrasonic skin care device is housed within this medium chamber to reduce energy loss during the transmission of ultrasonic waves to the skin. To facilitate adjustment of the ultrasonic transducer's position, the device also includes a drive shaft passing through the medium chamber, which is connected to the ultrasonic transducer to drive its movement. However, this structure, where the drive shaft passes through the medium chamber, can easily lead to leakage of the ultrasonic transducer fluid within the chamber. Utility Model Content

[0005] This application provides a skin care device to improve the technical problem that the structure of the drive shaft passing through the medium chamber easily leads to leakage of ultrasonic conductive fluid in the medium chamber.

[0006] In a first aspect, embodiments of this application provide a skin care device, comprising:

[0007] The housing assembly includes a dielectric chamber for storing an ultrasonic wave transmission medium. The inner wall of the dielectric chamber has a sound outlet window, and the inner wall of the dielectric chamber also includes a bottom wall opposite to the sound outlet window, the bottom wall having a guide structure.

[0008] A transducer assembly is movably disposed within the medium chamber, wherein the ultrasonic focus of the transducer assembly passes through the sound outlet window for penetration into the skin to be treated.

[0009] A first magnetic element is disposed within the dielectric chamber and fixedly connected to the transducer assembly; at least one of the first magnetic element and the transducer assembly is slidably mounted on the guide structure; and,

[0010] A second magnetic element is disposed outside the dielectric cavity and is magnetically connected to the first magnetic element. The second magnetic element is used to drive the first magnetic element to move, thereby driving the transducer assembly to move inside the dielectric cavity.

[0011] In some embodiments, the guide structure includes a guide rail disposed on the bottom wall, and at least one of the first magnetic element and the transducer assembly is slidably mounted on the guide rail.

[0012] In some embodiments, the transducer assembly and the guide rail form point contact, line contact, or rolling friction.

[0013] In some embodiments, the first magnetic element and the guide rail form point contact, line contact, or rolling friction.

[0014] In some embodiments, the guide rail includes:

[0015] Inner sidewall, the inner sidewall being connected to the bottom wall;

[0016] The outer sidewall, connected to the bottom wall and spaced apart from the inner sidewall; and,

[0017] The top wall is connected to the inner side wall and the outer side wall respectively, and a sliding space is formed between the inner side wall, the outer side wall, the top wall and the bottom wall. The first magnetic element is at least partially disposed in the sliding space.

[0018] In some embodiments, the transducer assembly includes a connection end that passes through the top wall to connect with the first magnetic element; wherein,

[0019] The inner sidewall is provided with a first protrusion extending into the sliding space, the first protrusion abutting against the first magnetic element or the connecting end; and / or

[0020] The outer wall is provided with a second protrusion that protrudes into the sliding space, and the second protrusion abuts against the first magnetic element or the connecting end; and / or

[0021] The top wall is provided with a third protrusion that protrudes into the sliding space, and the third protrusion abuts against the first magnetic element or the connecting end; and / or,

[0022] The bottom wall is provided with a fourth protrusion that protrudes into the sliding space, and the fourth protrusion abuts against the first magnetic element or the connecting end; and / or,

[0023] The outer surface of the connecting end or the first magnetic component includes a curved surface, which abuts against the inner surface of the sliding space to form a point contact or a line contact.

[0024] In some embodiments, at least one of the inner sidewall and the outer sidewall is separately formed from the bottom wall; and / or,

[0025] At least one of the inner sidewall and the outer sidewall is separately formed from the top wall.

[0026] In some implementations, the guide structure can guide the transducer assembly to perform two-dimensional or three-dimensional motion.

[0027] In some embodiments, the skin care device further includes a drive mechanism that is drively connected to the second magnetic element to drive the second magnetic element to move.

[0028] In some embodiments, the guide structure can guide the transducer assembly to rotate about a first axis passing through the bottom wall and the sound outlet window.

[0029] In some embodiments, the transducer assembly includes:

[0030] The mounting component is connected and fixed to the first magnetic component, such that the first magnetic component can drive the mounting component to rotate around the first axis; and,

[0031] An ultrasonic transducer is rotatably mounted on the mounting member. As the mounting member drives the ultrasonic transducer to rotate about the first axis, the ultrasonic transducer rotates relative to the mounting member to prevent the cables connected to the ultrasonic transducer from becoming entangled in the mounting member.

[0032] Secondly, embodiments of this application also provide a skin care device, comprising:

[0033] A housing assembly having a dielectric chamber for storing an ultrasonic wave transmission medium, the inner wall of which has a sound outlet window;

[0034] A transducer assembly is movably disposed within the medium chamber, wherein the ultrasonic focus of the transducer assembly passes through the sound outlet window for penetration into the skin to be treated.

[0035] A first magnetic element is disposed within the dielectric chamber and is fixedly connected to the transducer assembly; and,

[0036] The second magnetic element is disposed outside the dielectric cavity and is magnetically connected to the first magnetic element. The second magnetic element is used to drive the first magnetic element to perform two-dimensional or three-dimensional motion, thereby driving the transducer assembly to move inside the dielectric cavity.

[0037] The beneficial effects of the embodiments of this application are as follows:

[0038] The second magnetic component outside the dielectric chamber can drive the first magnetic component inside the dielectric chamber to move, thereby causing the first magnetic component to drive the transducer assembly to move. During this process, the movement of the first magnetic component and / or the transducer assembly is guided by the guide structure on the bottom wall of the dielectric chamber, which can ensure the reliability of the movement of the first magnetic component. As a result, the skin care device does not need to drive the transducer assembly through a drive shaft passing through the dielectric chamber, which can ultimately improve the technical problem that the ultrasonic transmission medium in the dielectric chamber is prone to leakage due to the drive shaft.

[0058] 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.

[0059] It should be noted that in this application, "and / or" describes the relationship between related objects, indicating that there can be three relationships. For example, A and / or B can represent: A existing alone, A and B existing simultaneously, or B existing alone. Additionally, the character " / ", unless otherwise specified, generally indicates that the related objects before and after it are in an "or" relationship.

[0060] This application provides a skin care device that can be used to provide ultrasonic care to the skin to be treated.

[0061] It should be noted that the skin care device may be used only to provide ultrasound care, or it may also be used to provide light care and electrical stimulation care, etc. The embodiments of this application do not limit this.

[0062] Phototherapy can include irradiating the skin to be treated with IPL light sources, laser light sources, or LED light sources to care for the skin.

[0063] Electrical stimulation care can be performed by applying electrical stimulation currents such as radiofrequency current, intermediate frequency current, and microcurrents (such as EMS current) to the skin to be treated.

[0064] Ultrasonic care may include emitting ultrasound waves (such as focused ultrasound) onto the skin to be treated in order to care for the skin, but this application does not limit this.

[0065] Below, we will first introduce the technical solution of this application in conjunction with providing ultrasonic care through skin care equipment.

[0066] Please refer to Figure 1 and Figure 2 The skin care device includes a housing assembly 100 and a transducer assembly 200. The housing assembly 100 has a medium chamber 121 for storing an ultrasonic wave transmission medium, and the inner wall of the medium chamber 121 has an exit window 122. The transducer assembly 200 is disposed within the medium chamber 121, and the focused ultrasonic wave of the transducer assembly 200 passes through the exit window 122 to be directed onto the skin to be treated.

[0067] Furthermore, compared to the transducer assembly 200, which emits ultrasound waves that propagate entirely through air, this application, by placing the transducer assembly 200 within the medium chamber 121, can reduce the loss of ultrasound waves emitted by the transducer assembly 200 during their propagation towards the skin, thereby increasing the energy intensity of the ultrasound waves entering the skin and ultimately improving the ultrasonic care effect of the skin care device.

[0068] In some embodiments, housing assembly 100 may include housing 11 and dielectric housing 12. Dielectric housing 12 may be at least partially disposed within housing 11. Dielectric housing 12 may have a dielectric chamber 121, or the dielectric housing 12 may form a dielectric chamber 121 between the dielectric housing 12 and the inner wall of housing 11.

[0069] Accordingly, the skin care device may also include a control circuit board 500, which is electrically connected to the transducer assembly 200 for controlling the operation of the transducer assembly 200. The control circuit board 500 is disposed within the housing 11 and outside the media chamber 121, thereby preventing damage to the control circuit board 500 by the ultrasonic wave transmission medium.

[0070] The housing assembly 100 may also include a sound-permeable diaphragm 13 that closes the sound outlet window 122. For example, the medium housing 12 is provided with a medium chamber 121, and the sound-permeable diaphragm 13 is connected to the medium housing 12 to close the sound outlet window 122.

[0071] In some embodiments, the transducer assembly 200 is movably disposed within the media chamber 121, and the skin care device further includes a first magnetic element 300 and a second magnetic element 400. The first magnetic element 300 is disposed within the media chamber 121 and is connected and fixed to the transducer assembly 200. The second magnetic element 400 is disposed outside the media chamber 121 and is magnetically connected to the first magnetic element 300. The second magnetic element 400 drives the first magnetic element 300 to move, thereby causing the transducer assembly 200 to move within the media chamber 121.

[0072] Therefore, the second magnetic element 400 outside the medium chamber 121 can drive the first magnetic element 300 inside the medium chamber 121 to move, thereby causing the first magnetic element 300 to drive the transducer assembly 200 to move. Consequently, the skin care device does not need to drive the transducer assembly 200 through a drive shaft passing through the medium chamber 121, ultimately improving the technical problem of easy leakage of the ultrasonic transmission medium inside the medium chamber 121 caused by the drive shaft.

[0073] In some embodiments, the second magnetic element 400 is used to drive the first magnetic element 300 to perform two-dimensional or three-dimensional motion, thereby driving the transducer assembly 200 to move within the dielectric chamber 121.

[0074] In other words, in some embodiments, this application provides a skin care device, including a housing assembly 100, a transducer assembly 200, a first magnetic element 300, and a second magnetic element 400. The housing assembly 100 has a medium chamber 121 for storing an ultrasonic wave transmission medium, and the inner wall of the medium chamber 121 has a sound outlet window 122. The transducer assembly 200 is movably disposed within the medium chamber 121, and the focused ultrasonic wave of the transducer assembly 200 passes through the sound outlet window 122 to be directed into the skin to be treated. The first magnetic element 300 is disposed within the medium chamber 121 and is connected and fixed to the transducer assembly 200. The second magnetic element 400 is disposed outside the medium chamber 121 and is magnetically connected to the first magnetic element 300. The second magnetic element 400 is used to drive the first magnetic element 300 to perform two-dimensional or three-dimensional motion, thereby causing the transducer assembly 200 to move within the medium chamber 121.

[0075] Furthermore, the first magnetic component 300 can also drive the transducer assembly 200 to perform two-dimensional or three-dimensional motion, so that the skin care device can meet more of the user's skin care needs.

[0076] For example, by driving the transducer assembly 200 to move, the ultrasonic focus of the transducer assembly 200 can move in a plane at a specific subcutaneous depth of the skin to be treated, thereby achieving large-area ultrasonic care of the skin to be treated.

[0077] For example, by driving the transducer assembly 200 to move, the ultrasonic focus of the transducer assembly 200 can be moved to different subcutaneous depths of the skin to be treated, so that the skin care device can accurately deliver ultrasonic energy to target tissues such as the fascia layer, thereby improving the ultrasonic care effect of the skin care device.

[0078] It is understood that when the second magnetic element 400 is used to drive the first magnetic element 300 to perform two-dimensional motion, the first magnetic element 300 can also drive the transducer assembly 200 to perform two-dimensional motion, thereby enabling the ultrasonic focus of the transducer assembly 200 to perform planar motion at a specific subcutaneous depth of the skin to be treated. When the second magnetic element 400 is used to drive the first magnetic element 300 to perform three-dimensional motion, the first magnetic element 300 can also drive the transducer assembly 200 to perform three-dimensional motion, thereby enabling the ultrasonic focus of the transducer assembly 200 to perform planar motion at a specific subcutaneous depth of the skin to be treated, and also to move between different subcutaneous depths. This application embodiment does not limit this.

[0079] Please continue to refer to this. Figure 3 and Figure 4In some embodiments, the skin care device further includes a guide structure 14, with at least one of the first magnetic element 300 and the transducer assembly 200 slidably mounted on the guide structure 14.

[0080] Therefore, during the process of the second magnetic element 400 driving the first magnetic element 300 to move so that the first magnetic element 300 drives the transducer assembly 200 to move, the guide structure 14 can guide the movement of the first magnetic element 300 and / or the transducer assembly 200, thereby ensuring the reliability of the movement of the first magnetic element 300.

[0081] In some embodiments, the guide structure 14 can guide the transducer assembly 200 to perform two-dimensional or three-dimensional motion. This allows the second magnetic element 400 to drive the first magnetic element 300 to perform two-dimensional or three-dimensional motion more stably and accurately.

[0082] The inventors discovered that in some embodiments, the guide structure 14 may include a guide rod, which is a long rod and installed on the side wall of the medium chamber 121. However, this structure causes the transducer assembly 200 to slide only in a one-dimensional straight line along the guide rod, making it difficult to meet the diverse skin care needs of users.

[0083] Based on this, in some embodiments, the inner wall of the media chamber 121 further includes a bottom wall 123 disposed opposite to the sound outlet window 122, and the bottom wall 123 is provided with a guide structure 14. Furthermore, the skin care device can flexibly provide guide structures 14 of different shapes and / or positions on the bottom wall 123 to meet more diverse skin care needs of users.

[0084] That is, in some embodiments, this application also provides a skin care device, including a housing assembly 100, a transducer assembly 200, a first magnetic element 300, and a second magnetic element 400. The housing assembly 100 has a medium chamber 121 for storing an ultrasonic wave transmission medium. The inner wall of the medium chamber 121 has a sound outlet window 122, and the inner wall of the medium chamber 121 also includes a bottom wall 123 opposite to the sound outlet window 122, with a guide structure 14 on the bottom wall 123. The transducer assembly 200 is movably disposed within the medium chamber 121, and the ultrasonic wave focal point of the transducer assembly 200 passes through the sound outlet window 122 to be directed into the skin to be treated. The first magnetic element 300 is disposed within the medium chamber 121 and connected and fixed to the transducer assembly 200. At least one of the first magnetic element 300 and the transducer assembly 200 is slidably mounted on the guide structure 14. The second magnetic element 400 is disposed outside the dielectric chamber 121. The second magnetic element 400 is magnetically connected to the first magnetic element 300. The second magnetic element 400 is used to drive the first magnetic element 300 to move, thereby driving the transducer assembly 200 to move inside the dielectric chamber 121.

[0085] The following text will mainly focus on the guide structure 14 installed on the bottom wall 123.

[0086] In some embodiments, the guide structure 14 includes a guide rail. The guide rail is disposed on the bottom wall 123. At least one of the first magnetic element 300 and the transducer assembly 200 is slidably mounted on the guide rail.

[0087] Furthermore, by sliding the first magnetic element 300 and / or the transducer assembly 200 within the guide rail, the movement of the first magnetic element 300 and the transducer assembly 200 can be better guided, thereby improving the reliability of the skin care device during ultrasonic treatment.

[0088] It is understandable that, since there is no direct physical connection between the first magnetic component 300 and the second magnetic component 400, when the skin care device vibrates or collides, the first magnetic component 300 and the second magnetic component 400 may become misaligned, which may lead to the magnetic connection between the first magnetic component 300 and the second magnetic component 400 being broken.

[0089] At this time, since the first magnetic component 300 and / or the transducer assembly 200 are slidably installed in the guide rail, the second magnetic component 400 only needs to move along the track of the guide rail for a maximum of one revolution to move to the vicinity of the first magnetic component 300 to re-establish the magnetic connection, thereby ensuring the reliability of the skin care device.

[0090] Taking the transducer assembly 200 slidingly mounted on the guide rail as an example, point contact, line contact or rolling friction can be formed between the transducer assembly 200 and the guide rail.

[0091] Furthermore, on the one hand, compared to surface contact between the transducer assembly 200 and the guide rail, the point contact and line contact structures can reduce the friction between the transducer assembly 200 and the guide rail, thereby allowing the second magnetic element 400 to drive the first magnetic element 300 and the transducer assembly 200 to move more smoothly. On the other hand, compared to sliding friction between the transducer assembly 200 and the guide rail, the rolling friction structure can reduce the friction between the transducer assembly 200 and the guide rail, thereby allowing the second magnetic element 400 to drive the first magnetic element 300 and the transducer assembly 200 to move more smoothly.

[0092] Taking the first magnetic component 300 slidingly mounted on the guide rail as an example, the first magnetic component 300 and the guide rail form point contact, line contact or rolling friction.

[0093] Furthermore, on the one hand, compared to surface contact between the first magnetic component 300 and the guide rail, the point contact and line contact structures can reduce the friction between the first magnetic component 300 and the guide rail, thereby allowing the second magnetic component 400 to drive the first magnetic component 300 and the transducer assembly 200 to move more smoothly. On the other hand, compared to sliding friction between the first magnetic component 300 and the guide rail, the rolling friction structure can reduce the friction between the first magnetic component 300 and the guide rail, thereby allowing the second magnetic component 400 to drive the first magnetic component 300 and the transducer assembly 200 to move more smoothly.

[0094] In some embodiments, the guide rail includes an inner sidewall 141 and an outer sidewall 142. The inner sidewall 141 is connected to the bottom wall 123. The outer sidewall 142 is connected to the bottom wall 123 and spaced apart from the inner sidewall 141. A first magnetic element 300 is at least partially disposed between the inner sidewall 141 and the outer sidewall 142. Thus, the first magnetic element 300 can be guided by the inner sidewall 141 and the outer sidewall 142, and / or, the portion of the transducer assembly 200 connected to the first magnetic element 300 can be guided by the inner sidewall 141 and the outer sidewall 142.

[0095] In some embodiments, the guide rail further includes a top wall 143. An inner wall 141 is connected to a bottom wall 123. The top wall 143 is connected to both the inner wall 141 and the outer wall 142, and a sliding space 144 is formed between the inner wall 141, the outer wall 142, the top wall 143, and the bottom wall 123. The first magnetic element 300 is at least partially disposed within the sliding space 144.

[0096] Furthermore, the inner wall 141, outer wall 142, top wall 143, and bottom wall 123 can provide a better limiting effect for the first magnetic element 300, and / or the inner wall 141, outer wall 142, top wall 143, and bottom wall 123 can provide a better limiting effect for the portion of the transducer assembly 200 connected to the first magnetic element 300, so as to prevent the first magnetic element 300 from detaching from the guide rail, thereby improving the stability and reliability of the skin care device.

[0097] In some embodiments, the transducer assembly 200 includes a connection end 211 that passes through the top wall 143 to connect with the first magnetic element 300.

[0098] Therefore, in this embodiment, at least one of the inner wall 141, outer wall 142, top wall 143, and bottom wall 123 may directly contact the first magnetic element 300 to prevent the first magnetic element 300 from detaching from the guide rail. Optionally, at least one of the inner wall 141, outer wall 142, top wall 143, and bottom wall 123 may contact the connection end 211 of the transducer assembly 200, thereby indirectly preventing the first magnetic element 300 from detaching from the guide rail by preventing the transducer assembly 200 from detaching from the guide rail. This embodiment does not limit this approach.

[0099] In some embodiments, the guide rail may be arranged around the bottom wall 123. Correspondingly, the inner wall 141, the outer wall 142 and the top wall 143 may all be annular, and the outer wall 142 surrounds the outer periphery of the inner wall 141.

[0100] The top wall 143 may also include a clearance groove 1431 communicating with the sliding space 144, and the connection end 211 of the transducer assembly 200 passes through the clearance groove 1431 to connect with the first magnetic element 300.

[0101] Please continue to refer to this. Figure 5 In some embodiments, the outer surface of the connecting end 211 or the first magnetic element 300 includes a curved surface, which abuts against the inner surface of the sliding space 144 to form a point contact or a line contact.

[0102] For example, the curved surface can be spherical. The spherical structure can reduce the contact area between the curved surface and the inner surface of the sliding space 144, thereby enabling the curved surface to form point contact or line contact with the inner surface of the sliding space 144. This reduces the friction force when the corresponding first magnetic component 300 or connecting end 211 moves, ultimately allowing the second magnetic component 400 to drive the first magnetic component 300 and transducer assembly 200 to move more smoothly.

[0103] In some embodiments, the inner sidewall 141 is provided with a first protrusion 1411 that protrudes into the sliding space 144, and the first protrusion 1411 abuts against the first magnetic element 300 or the connecting end 211.

[0104] Therefore, compared to the entire inner sidewall 141 contacting the corresponding first magnetic element 300 or connecting end 211, the first protrusion 1411 can reduce the contact area between the inner sidewall 141 and the corresponding first magnetic element 300 or connecting end 211, thereby reducing the friction force when the corresponding first magnetic element 300 or connecting end 211 moves, ultimately allowing the second magnetic element 400 to drive the first magnetic element 300 and transducer assembly 200 to move more smoothly.

[0105] The cross-section of the first protrusion 1411 can be trapezoidal, triangular, semi-circular, etc., and the embodiments of this application do not limit it.

[0106] The first protrusion 1411 may surround the outer periphery of the inner wall 141.

[0107] In some embodiments, the outer wall 142 is provided with a second protrusion 1421 that protrudes into the sliding space 144, and the second protrusion 1421 abuts against the first magnetic element 300 or the connecting end 211.

[0108] Therefore, compared to the outer sidewall 142 contacting the corresponding first magnetic element 300 or connecting end 211, the second protrusion 1421 can reduce the contact area between the outer sidewall 142 and the corresponding first magnetic element 300 or connecting end 211, thereby reducing the friction force when the corresponding first magnetic element 300 or connecting end 211 moves, and ultimately enabling the second magnetic element 400 to drive the first magnetic element 300 and transducer assembly 200 to move more smoothly.

[0109] The cross-section of the second protrusion 1421 can be trapezoidal, triangular, semi-circular, etc., and the embodiments of this application do not limit it.

[0110] The second protrusion 1421 may surround the inner periphery of the outer wall 142.

[0111] In some embodiments, the bottom wall 123 is provided with a fourth protrusion 1231 that protrudes into the sliding space 144, and the fourth protrusion 1231 abuts against the first magnetic element 300 or the connecting end 211.

[0112] Therefore, compared to the portion of the bottom wall 123 located within the sliding space 144 that is in contact with the corresponding first magnetic element 300 or connecting end 211, the fourth protrusion 1231 can reduce the contact area between the bottom wall 123 and the corresponding first magnetic element 300 or connecting end 211, thereby reducing the frictional force when the corresponding first magnetic element 300 or connecting end 211 moves, ultimately allowing the second magnetic element 400 to drive the first magnetic element 300 and the transducer assembly 200 to move more smoothly.

[0113] The cross-section of the fourth protrusion 1231 can be trapezoidal, triangular, semi-circular, etc., and this application embodiment does not limit it.

[0114] The fourth protrusion 1231 may surround the inner periphery of the outer wall 142.

[0115] Please continue to refer to this. Figure 6 In some embodiments, the top wall 143 is provided with a third protrusion 1434 protruding into the sliding space 144, the third protrusion 1434 abutting against the first magnetic element 300 or the connecting end 211.

[0116] Therefore, compared to the top wall 143 contacting the corresponding first magnetic element 300 or connecting end 211, the third protrusion 1434 can reduce the contact area between the outer wall 142 and the corresponding first magnetic element 300 or connecting end 211, thereby reducing the friction force when the corresponding first magnetic element 300 or connecting end 211 moves, ultimately allowing the second magnetic element 400 to drive the first magnetic element 300 and transducer assembly 200 to move more smoothly.

[0117] The cross-section of the third protrusion 1434 can be trapezoidal, triangular, semi-circular, etc., and the embodiments of this application do not limit it.

[0118] The third protrusion 1434 may surround the inner periphery of the outer wall 142.

[0119] In some embodiments, the top wall 143 may include a first top wall 1432 and a second top wall 1433, the first top wall 1432 being circumferentially connected to the outer side wall 142, and the second top wall 1433 being circumferentially connected to the inner side wall 141. Furthermore, a clearance groove 1431 is formed between the inner peripheral side of the first top wall 1432 and the outer peripheral side of the second top wall 1433.

[0120] Therefore, the fourth protrusion 1231 may be provided only on the first top wall 1432, or only on the second top wall 1433, or both the first top wall 1432 and the second top wall 1433 may be provided with the fourth protrusion 1231. This application embodiment does not limit this.

[0121] In some embodiments, at least one of the inner sidewall 141 and the outer sidewall 142 is separately formed from the bottom wall 123. This facilitates the installation of the transducer assembly 200 and the first magnetic element 300.

[0122] For example, when the inner wall 141 and the outer wall 142 are both separately formed from the bottom wall 123, the inner wall 141 can be integrally formed with the first top wall 1432, and the outer wall 142 can be integrally formed with the second top wall 1433. Furthermore, both the inner wall 141 and the outer wall 142 are snap-fitted to the bottom wall 123.

[0123] One possible assembly mode for the transducer assembly 200 is as follows: First, the inner sidewall 141 is installed on the bottom wall 123; then, the transducer assembly 200 and the first magnetic element 300 are disposed on the outer periphery of the second top wall 1433; next, the outer sidewall 142 is installed on the bottom wall 123, such that the connecting end 211 of the transducer assembly 200 passes through the first top wall 1432 and the second top wall 1433, and the first magnetic element 300 is disposed in the sliding space 144.

[0124] When the outer sidewall 142 and the bottom wall 123 are separately formed and the inner sidewall 141 and the bottom wall 123 are integrally formed, one assembly mode of the transducer assembly 200 can be: first, the transducer assembly 200 and the first magnetic element 300 are disposed on the outer periphery of the second top wall 1433; then, the outer sidewall 142 is installed on the bottom wall 123, so that the connecting end 211 of the transducer assembly 200 passes through the first top wall 1432 and the second top wall 1433, and the first magnetic element 300 is disposed in the sliding space 144.

[0125] When the inner sidewall 141 and the bottom wall 123 are separately formed and the outer sidewall 142 and the bottom wall 123 are integrally formed, one assembly mode of the transducer assembly 200 can be as follows: First, the transducer assembly 200 and the first magnetic element 300 are disposed on the inner circumferential side of the first top wall 1432; then, the inner sidewall 141 is installed on the bottom wall 123, so that the connecting end 211 of the transducer assembly 200 passes through the first top wall 1432 and the second top wall 1433, and the first magnetic element 300 is disposed in the sliding space 144.

[0126] In some embodiments, at least one of the inner sidewall 141 and the outer sidewall 142 is separately formed from the top wall 143. This facilitates the installation of the transducer assembly 200 and the first magnetic element 300.

[0127] For example, the first top wall 1432 and the outer side wall 142 are formed separately, and the second top wall 1433 and the inner side wall 141 are formed separately. Then, one assembly mode of the transducer assembly 200 can be: first, the connecting end 211 of the transducer assembly 200 and the first magnetic element 300 are installed between the inner side wall 141 and the outer side wall 142; then, the first top wall 1432 is installed on the outer side wall 142, and the second top wall 1433 is installed on the inner side wall 141.

[0128] Please combine Figure 2 and Figure 3 In some embodiments, the guide structure 14 can guide the transducer assembly 200 to rotate about a first axis L1, which passes through the bottom wall 123 and the sound outlet window 122. This allows the ultrasonic focus of the transducer assembly 200 to move in a planar motion at a specific subcutaneous depth of the skin to be treated, thereby achieving large-area ultrasonic care of the skin to be treated.

[0129] In some embodiments, the transducer assembly 200 includes a mounting member 21 and an ultrasonic transducer 22. The mounting member 21 is fixedly connected to a first magnetic member 300 such that the first magnetic member 300 can drive the mounting member 21 to rotate about a first axis L1. The ultrasonic transducer 22 is rotatably mounted on the mounting member 21. As the mounting member 21 drives the ultrasonic transducer 22 to rotate about the first axis L1, the ultrasonic transducer 22 rotates relative to the mounting member 21 to prevent the cable connected to the ultrasonic transducer 22 from becoming entangled in the mounting member 21.

[0130] Taking the guide structure 14 as an example that guides the transducer assembly 200 to rotate around the first axis L1, the ultrasonic transducer 22 is provided with a first electrical connection terminal for connecting cables. During the process of the first magnetic element 300 driving the mounting member 21 and the ultrasonic transducer 22 to rotate around the first axis L1, the ultrasonic transducer 22 also rotates relative to the mounting member 21, so that the first electrical connection terminal can always face the same side of the first axis L1 in the circumferential direction during the movement of the transducer assembly 200, so as to avoid cable tangling.

[0131] For example, the ultrasonic transducer 22 is rotatably mounted on the mounting member 21 about a second axis L2. The second axis L2 can be the centerline of the ultrasonic transducer 22, or it can be parallel to the centerline of the ultrasonic transducer 22; this embodiment does not limit this.

[0132] In some embodiments, the skin care device further includes a drive mechanism 600, which is drively connected to the second magnetic element 400 for driving the second magnetic element 400 to move.

[0133] The drive mechanism 600 may include a transmission mechanism 61, which is connected to the second magnetic element 400 to drive the second magnetic element 400 to move.

[0134] In some embodiments, the drive mechanism 600 may further include a motor 62, which is connected to the transmission mechanism 61 so that the motor 62 drives the second magnetic element 400 to move via the transmission mechanism 61. Furthermore, the motor 62 can achieve precise control of the second magnetic element 400, thereby ensuring that the second magnetic element 400 can also accurately drive the first magnetic element 300 and the transducer assembly 200 to move.

[0135] For example, the transmission mechanism 61 may include a turntable. A second magnetic element 400 is mounted on the turntable. The turntable is also connected and fixed to the output shaft of the motor 62. Furthermore, the motor 62 can drive the turntable to rotate, so that the turntable drives the second magnetic element 400 to rotate.
