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 point, generating high temperatures that cause the target tissue 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 focal point of the ultrasonic transducer is directed into the fascia layer, allowing the energy waves generated by the transducer to directly act on the fascia layer, causing it to contract.

[0004] In related technologies, the depth to which the focal point of an ultrasound transducer penetrates the subcutaneous layer is fixed. However, different users have different skin types, causing the energy waves of the ultrasound transducer to not accurately reach the fascia layer of some users. Utility Model Content

[0054] The embodiments of this application are described in detail below. Examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this application, and should not be construed as limiting this application.

[0055] Furthermore, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a process, method, article, or apparatus. Without further limitation, an element defined by the phrase "comprising one..." does not exclude the presence of other identical elements in the process, method, article, or apparatus that includes said element.

[0056] This application provides a skin care device that can be used to provide ultrasonic care to the skin to be treated.

[0057] 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.

[0058] 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.

[0059] 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.

[0060] 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.

[0061] Below, we will first introduce the technical solution of this application in conjunction with providing ultrasonic care through skin care equipment.

[0062] 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.

[0063] Furthermore, compared to the transducer assembly 200 which uses air as the propagation medium to deliver ultrasound waves to the skin, this application reduces the loss of ultrasound waves delivered by the transducer assembly 200 to the skin by placing the transducer assembly 200 inside the medium chamber 121, thereby increasing the energy intensity of the ultrasound waves entering the skin and ultimately improving the ultrasound care effect of the skin care device.

[0064] It should be noted that the ultrasonic transmission medium can be an ultrasonic transmission fluid.

[0065] In some embodiments, the housing assembly 100 may include a housing 11 and a dielectric housing 12. The dielectric housing 12 may be at least partially disposed within the housing 11. The dielectric housing 12 may have a dielectric chamber 121 therein, or the dielectric housing 12 may form a dielectric chamber 121 between the inner wall of the housing 11 and the outer wall of the housing 12.

[0066] Accordingly, the skin care device may also include a control circuit board 300, which is electrically connected to the transducer assembly 200 for controlling the operation of the transducer assembly 200. The control circuit board 300 is disposed within the housing 11 and outside the media chamber 121, thereby preventing damage to the control circuit board 300 by the ultrasonic wave transmission medium.

[0067] 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.

[0068] Through the inventor's creative work, it was discovered that in related technologies, a structure can be adopted to adjust the position of the transducer assembly 200, thereby adjusting the subcutaneous depth of the ultrasonic wave focused on the skin to be treated. Therefore, the skin care device also includes a drive shaft passing through the medium chamber 121, which is connected to the transducer assembly 200 to drive its movement. However, the structure of the drive shaft passing through the medium chamber 121 is prone to causing leakage of the ultrasonic wave conductive fluid in the medium chamber 121.

[0069] Based on this, in this embodiment of the application, the skin care device further includes a depth adjustment member 400, which is mounted on the housing assembly 100 and includes a contact portion 41 for abutting against the skin to be treated. Along the direction of the transducer assembly 200 toward the sound outlet window 122, the position of the contact portion 41 relative to the sound outlet window 122 is adjustable to adjust the distance between the sound outlet window 122 and the skin to be treated.

[0070] Therefore, by adjusting the position of the contact part 41 relative to the sound outlet window 122, the position of the sound outlet window 122 and the transducer assembly 200 relative to the skin to be treated can be adjusted, thereby adjusting the depth of the ultrasonic focus of the transducer assembly 200 into the skin to be treated, and ultimately enabling the energy wave of the ultrasonic transducer to be more accurately injected into the appropriate depth of the skin to be treated.

[0071] Furthermore, since the contact portion 41 is located outside the medium chamber 121, the position of the contact portion 41 can be adjusted without the need for a drive shaft passing through the medium chamber 121, thereby avoiding leakage of the ultrasonic transducer fluid in the medium chamber 121 caused by the structure of the drive shaft passing through the medium chamber 121.

[0072] The depth adjustment element 400 can be installed on the housing 11 and / or the media housing 12.

[0073] 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.

[0074] That is to say, the depth adjustment member 400 may be connected only to the outer shell 11, or only to the medium shell 12, or both to the outer shell 11 and the medium shell 12. This application embodiment does not limit this.

[0075] Please continue to refer to this. Figure 3In some embodiments, the contact portion 41 is arranged around the sound outlet window 122. Furthermore, on the one hand, the contact portion 41 does not block the ultrasonic waves emitted from the sound outlet window 122; on the other hand, compared to providing the contact portion 41 only on one side of the sound outlet window 122 in the circumferential direction, the contact portion 41 in this embodiment has a larger area, thereby increasing the contact area between the contact portion 41 and the skin to be treated, ultimately improving the stability and reliability of the contact portion 41 when it comes into contact with the skin to be treated.

[0076] Please continue to refer to this. Figure 4 The depth adjustment member 400 may also include a mounting portion 42. Along the direction of the transducer assembly 200 toward the sound outlet window 122, the mounting portion 42 is located on the side of the contact portion 41 near the transducer assembly 200. The mounting portion 42 is connected to the housing assembly 100.

[0077] It is understood that the mounting part 42 may be mounted only on the outer casing 11, for example, the mounting part 42 may be sleeved on the outer periphery of the outer casing 11. The mounting part 42 may also be mounted only on the medium housing 12, for example, the mounting part 42 may be sleeved on the outer periphery of the medium housing 12. Of course, as... Figure 2 As shown, the mounting part 42 can also be movably disposed between the inner wall of the outer casing 11 and the outer wall of the medium casing 12, but this embodiment does not limit this.

[0078] Furthermore, the depth adjustment member 400 can be installed through the mounting part 42; and when the contact part 41 abuts against the skin to be treated, since the mounting part 42 is located on the side of the contact part 41 closer to the transducer assembly 200, the mounting part 42 can be prevented from abutting against the skin to be treated, thereby preventing the mounting part 42 from interfering with the contact part 41 abutting against the skin to be treated.

[0079] In some embodiments, the mounting portion 42 is mounted on the housing assembly 100, and the contact portion 41 is movably connected to the mounting portion 42 so that the contact portion 41 can move relative to the housing assembly 100.

[0080] Please continue to refer to this. Figure 5 For example, the depth adjustment member 400 also includes a deformable connection portion 43, through which the contact portion 41 and the mounting portion 42 are connected, thereby allowing the contact portion 41 to move relative to the mounting portion 42, so that the contact portion 41 can move relative to the mounting portion 42.

[0081] For example, the deformable connection 43 can be a flexible connection.

[0082] Of course, the contact part 41 and the mounting part 42 can also be connected by a telescopic rod, or the contact part 41 and the mounting part 42 can be movably connected by a sliding connection or other means. This application embodiment does not limit this.

[0083] In some embodiments, the mounting portion 42 is movably connected to the housing assembly 100, and the mounting portion 42 is movable relative to the housing assembly 100, thereby driving the contact portion 41 to move.

[0084] It is understood that the mounting part 42 can be mounted on the housing assembly 100 in a spiral direction. Furthermore, by driving the mounting part 42 to move forward in a spiral direction, the contact part 41 can be moved closer to or away from the sound outlet window 122, thereby making the stroke accuracy of the contact part 41 when moving closer to or away from the sound outlet window 122 higher.

[0085] Please continue to refer to this. Figure 6 For example, the mounting portion 42 is threaded onto the housing assembly 100, allowing the mounting portion 42 to move in a helical direction. Furthermore, by screwing the mounting portion 42, the contact portion 41 can be driven to move. Moreover, the threaded connection structure also allows the mounting portion 42 to be rotated and fixed in different positions to meet the user's various position adjustment needs.

[0086] Optionally, the mounting part 42 can be mounted on the housing assembly 100 in a linear direction. This embodiment does not limit this. By moving the mounting part 42 in a linear direction, the mounting part 42 and the contact part 41 can be adjusted to the target position more quickly.

[0087] Please continue to refer to this. Figure 7 In some embodiments, one of the mounting portion 42 and the housing assembly 100 is provided with a guide groove 111, and the other of the mounting portion 42 and the housing assembly 100 is provided with a guide portion 44, which is slidably mounted in the guide groove 111. Thus, the cooperation between the guide groove 111 and the guide portion 44 can provide a better guiding effect for the movement of the mounting portion 42, thereby improving the position adjustment accuracy of the contact portion 41 of the depth adjustment member 400.

[0088] The guide groove 111 may include a spiral groove that extends spirally along the transducer assembly 200 toward the sound outlet window 122, so that the mounting part 42 can move in the spiral direction.

[0089] Please continue to refer to this. Figure 8 The guide groove 111 may include a straight groove that extends along the transducer assembly 200 toward the sound outlet window 122. The guide portion 44 is slidably mounted on the guide groove 111 so that the mounting portion 42 can move in a straight direction.

[0090] The number of guide grooves 111 can be one or at least two; correspondingly, the number of guide parts 44 can also be one or at least two. The guide grooves 111 and guide parts 44 slide in one-to-one cooperation. This application embodiment does not limit this.

[0091] Therefore, when the number of guide grooves 111 is at least two, multiple sliding fits can be formed between the mounting part 42 and the housing assembly 100, thereby improving the reliability and stability of the movement of the mounting part 42 and the entire depth adjustment member 400.

[0092] In some implementations, at least two guide grooves 111 may be arranged circumferentially around the sound window 122.

[0093] For example, the housing assembly 100 has a nursing end 124, and a sound outlet window 122 is located on the end face of the nursing end 124. The mounting portion 42 can then be cylindrical to fit over the nursing end 124. Correspondingly, at least two guide grooves 111 can be spaced apart on the inner circumference of the mounting portion 42.

[0094] Correspondingly, one axial end of the mounting part 42 is connected to a contact part 41, so that the contact part 41 is arranged around the sound outlet window 122.

[0095] Please continue to refer to this. Figure 9 In some embodiments, the housing assembly 100 is provided with a first positioning structure 123, and the depth adjustment member 400 is provided with a second positioning structure 45. The second positioning structure 45 is used to cooperate with the first positioning structure 123 so that the contact portion 41 is fixed at a preset distance from the sound outlet window 122.

[0096] For example, the skin care device may have at least two depth settings, with the contact portion 41 located at different preset distances from the sound outlet window 122 at different depth settings. This allows the user to more easily adjust the contact portion 41 to the appropriate position.

[0097] The second positioning structure 45 and the first positioning structure 123 can be used to fix each other by magnetic attraction, snap-fit, or plug-in connection. This application embodiment does not limit this.

[0098] For example, one of the first positioning structure 123 and the second positioning structure 45 includes a snap-fit ​​portion, and the other of the first positioning structure 123 and the second positioning structure 45 includes a positioning groove. The snap-fit ​​portion can snap into the positioning groove so that the contact portion 41 is fixed at a preset distance from the sound outlet window 122. Furthermore, after the contact portion 41 is adjusted to a suitable position, it can be snapped and limited by the first positioning structure 123 and the second positioning structure 45.

[0099] The snap-fit ​​portion may include a resilient snap-fit ​​portion. For example, the resilient snap-fit ​​portion may include a ball screw, a spring clip, etc., and this application embodiment does not limit this.

[0100] Furthermore, when the user adjusts the position of the contact part 41, the elastic locking part can be compressed to disengage from the corresponding positioning groove. After the contact part 41 is adjusted to the appropriate position, the elastic locking part can return to its original position and engage with the corresponding positioning groove.

[0101] In some embodiments, the number of first positioning structures 123 is at least two, and the second positioning structure 45 can be connected to different first positioning structures 123 so that the contact portion 41 is fixed at at least two preset distances from the sound outlet window 122. Furthermore, the user can more easily adjust the contact portion 41 to multiple suitable positions.

[0102] In some embodiments, at least two first positioning structures 123 are spaced apart along the moving direction of the contact portion 41.

[0103] For example, when the mounting part 42 can move in a straight line, at least two first positioning structures 123 can be spaced apart in a straight line.

[0104] Optionally, the mounting part 42 can move in a spiral direction, and at least two first positioning structures 123 can be arranged at intervals in a spiral direction. This application embodiment does not limit this.

[0105] like Figure 7 As shown in Figure 8, in some embodiments, at least one of the housing assembly 100 and the depth adjustment member 400 is provided with an indicator 14 for indicating the position information of the contact portion 41 relative to the sound outlet window 122.

[0106] Furthermore, the indicator 14 allows users to easily adjust the contact part 41 to a more suitable position, thereby improving the skin care effect of the skin care device.

[0107] For example, indicator 14 may include a scale and a pointer. One of the housing assembly 100 and the depth adjustment member 400 is provided with a scale, and the other is provided with a pointer. When the contact portion 41 is in different positions relative to the sound outlet window 122, the pointer points to different positions of the scale.

[0108] The indicator mark 14 can be integrally formed on the corresponding housing assembly 100 and / or depth adjustment member 400. The indicator mark 14 can also be a sprayed or printed ink layer, etc. This application embodiment does not limit this.

[0109] like Figure 4 As shown, in some embodiments, the skin care device further includes an electrode 500 for applying electrical stimulation to the skin to be treated.

[0110] For example, electrode 500 can be used to apply electrical stimulation currents such as radiofrequency current, intermediate frequency current, and microcurrent (such as EMS current) to the skin to be treated for skin care.

[0111] Electrode 500 may be at least partially disposed on contact portion 41, such that electrode 500 may follow contact portion 41 to abut against the skin to be treated for electrical stimulation care of the skin to be treated.

[0112] In some embodiments, there may be multiple electrodes 500, which are spaced apart circumferentially along the contact portion 41.

[0113] In some embodiments, the skin care device further includes a current output element 600 and a deformable electrical connector 700. The current output element 600 is at least partially within the housing assembly 100 for outputting current. The deformable electrical connector 700 is used to connect the electrode 500 and the current output element 600, and at least one of the deformable electrical connector 700 and the current output element 600 extends through the housing assembly 100.

[0114] Furthermore, when the contact portion 41 drives the electrode 500 to move, the deformable electrical connector 700 can adapt to the terrain deformation.

[0115] For example, the deformable electrical connector 700 includes at least one of a spring pin, a resilient conductive element, a flexible ribbon cable, and a wire.

[0116] It should be noted that the current output element 600 may be disposed within the housing assembly 100. Furthermore, the current output element 600 may be exposed outside the housing assembly 100, thereby allowing the electrical connector 700 to connect the electrode 500 and the current output element 600 from the outside of the housing assembly 100.

[0117] Optional, such as Figure 2 As shown, a deformable electrical connector 700 may also be disposed within the housing assembly 100. For example, the deformable electrical connector 700 may include a spring pin, a flexible ribbon cable, or a wire, and may be disposed within the housing assembly 100 to be electrically connected to a current output device 600 within the housing assembly 100.
