Description

Technical Field

[0001] The present application relates to the technical field of beauty equipment, and in particular to an ultrasonic beauty instrument and a control method thereof, a focused ultrasound output device and a storage medium. Background Art

[0002] At present, the focal length adjustment of the ultrasonic wave output by the ultrasonic beauty instrument is usually achieved by controlling the electromechanical device to drive the ultrasonic transducer to move in the direction close to or away from the skin, so that the depth of action of the focus of the ultrasonic transducer inside the skin changes, thereby achieving the adjustment of the ultrasonic focal length. When the electromechanical device drives the ultrasonic transducer away from the skin, the focus of the ultrasonic transducer will move toward the surface of the skin; when the electromechanical device drives the ultrasonic transducer close to the skin, the focus of the ultrasonic transducer will move deep into the skin. When the ultrasonic transducer is displaced under the drive of the electromechanical device, the wire of the ultrasonic transducer moves or bends with the movement of the electromechanical device. In order to meet the need to adjust the ultrasonic focal length during the use of the ultrasonic beauty instrument, the ultrasonic transducer will frequently displace under the drive of the electromechanical device, and the wire of the ultrasonic transducer will frequently bend with the movement of the electromechanical device. Frequent bending will reduce the life of the wire, thereby reducing the life of the ultrasonic transducer.

[0023] See also Figure 1 and Figure 2 , Figure 1 This is a structural block diagram of an ultrasonic beauty instrument 100 provided in an embodiment of the present application. Figure 2 for Figure 1 The structure diagram of the focused ultrasound output device 10 is shown in FIG. Figure 1 and Figure 2As shown, the ultrasonic beauty instrument 100 includes a focused ultrasonic output device 10 and a control module 20. The focused ultrasonic output device 10 includes an ultrasonic focusing component 11, a driving component 12 and an ultrasonic output component 13. The ultrasonic focusing component 11 includes an elastic membrane 111, a receiving cavity 112 and a fluid 113. The receiving cavity 112 has an opening 1121. The elastic membrane 111 closes the opening 1121 and cooperates with the receiving cavity 112 to form a closed receiving space 114. The fluid 113 is received in the receiving space 114. The driving component 12 is used to drive the elastic membrane 111 to deform and form a curved surface. The ultrasonic output component 13 is arranged on one side of the elastic membrane 111 or on one side of the receiving cavity 112. The ultrasonic output component 13 is used to output ultrasonic waves to the ultrasonic focusing component 11, so as to be focused and outputted by the ultrasonic focusing component 11. The control module 20 is used to control the driving component 12 to drive the elastic membrane 111 to deform to form a curved surface, and to control and adjust the deformation degree of the elastic membrane 111 to adjust the curvature radius of the formed curved surface, thereby adjusting the focal length of the ultrasonic wave output by the ultrasonic output component 13.

[0024] The ultrasonic beauty instrument 100 provided in the embodiment of the present application drives the elastic membrane 111 of the ultrasonic focusing component 11 to deform to form a curved surface, and controls and adjusts the deformation degree of the elastic membrane 111 to adjust the curvature radius of the formed curved surface, thereby adjusting the focal length of the ultrasonic wave output by the ultrasonic output component 13, thereby achieving accurate and rapid adjustment of the ultrasonic focal length, without moving the ultrasonic output component 13, eliminating the need for electromechanical devices, and increasing the service life of the ultrasonic output component 13. It can also make the focal length adjustment more accurate, faster, and more efficient, thereby improving the user experience and facilitating the miniaturization and automation of the ultrasonic beauty instrument 100.

[0025] The ultrasonic wave outputted by the ultrasonic output component 13 is focused when passing through the ultrasonic focusing component 11 , so that the focused ultrasonic wave output device 10 outputs focused ultrasonic waves.

[0026] When the ultrasonic beauty instrument 100 acts on the skin, the ultrasonic waves output by the ultrasonic output component 13 are focused on the inner layer of the skin, the size of the area where the focused ultrasonic waves act is small, and the ultrasonic energy can be concentrated on a certain area in the skin. By adjusting the focal length of the ultrasonic waves output by the ultrasonic output component 13, the output depth of the ultrasonic waves output by the ultrasonic output component 13 acting on the skin can be adjusted.

[0027] The elastic film 111 is permeable to ultrasound waves. The material of the elastic film 111 may be PI (Polyimide), PET (Polyethylene glycol terephthalate), PTFE (Polytetrafluoroethylene), etc. It may also be a film made of other materials that is permeable to ultrasound waves. The elastic film 111 is elastic and can be deformed without breaking within a certain force range. The shape of the elastic film 111 may be circular, rectangular, or any other shape.

[0028] The fluid 113 can conduct ultrasonic waves. In some embodiments, the fluid 113 can be a mixture of glycerin and water. In other embodiments, the fluid 113 can be other types of fluids that can conduct ultrasonic waves. The fluid 113 can fill the containing space 114 .

[0029] Wherein, the ultrasonic output component 13 may include an ultrasonic transducer for converting an electrical signal into an acoustic signal to emit an ultrasonic wave. The ultrasonic transducer includes a piezoelectric vibrator, a positive wire and a negative wire, wherein the piezoelectric vibrator is connected to the positive wire and the negative wire respectively, and the positive wire and the negative wire are connected to a power amplifier circuit respectively, and the power amplifier circuit is used to amplify the electrical signal output by the power supply and output the amplified electrical signal to the piezoelectric vibrator through the positive wire and the negative wire, and the piezoelectric vibrator is used to convert the electrical signal into an acoustic signal to emit an ultrasonic wave. Wherein, the piezoelectric vibrator may be in a plate shape, or in a concave shape, such as a parabola shape, a spherical shape, etc. In some embodiments, the piezoelectric vibrator is in a concave shape, and the concave piezoelectric vibrator can pre-focus the emitted ultrasonic wave, and the pre-focused ultrasonic wave is re-focused when passing through the ultrasonic focusing component 11, and the piezoelectric vibrator is set to a concave shape, which is conducive to focusing the emitted ultrasonic wave.

[0030] In some embodiments, the concave piezoelectric vibrator may include a plurality of sub-piezoelectric vibrators, and the focused ultrasound output device 10 may also include a plurality of driving units, each driving unit is connected to a sub-piezoelectric vibrator, and the driving unit is used to drive the connected sub-piezoelectric vibrators to rotate, and the control module 20 may be used to control the plurality of driving units to drive the plurality of sub-piezoelectric vibrators to rotate, so as to adjust the radius of curvature of the piezoelectric vibrator, and then adjust the focal length of the ultrasonic wave emitted by the piezoelectric vibrator. The control module 20 may adjust the focal length of the output ultrasonic wave by controlling the rotation of the plurality of sub-piezoelectric vibrators and the deformation of the elastic film 111. In other embodiments, the concave piezoelectric vibrator does not rotate, and the control module 20 adjusts the focal length of the output ultrasonic wave by controlling the deformation of the elastic film 111.

[0031] The control module 20 may include a single chip microcomputer, a CPU (central processing unit), a DSP (digital signal processing) and other processing chips.

[0032] In some embodiments, Figure 2 As shown, the accommodating cavity 112 also includes a bottom wall 1122, which is opposite to the opening 1121. The driving assembly 12 includes a moving member 121, which is arranged on the side of the elastic membrane 111 away from the bottom wall 1122, and the moving member 121 can move in a direction close to or away from the bottom wall 1122.

[0033] The control module 20 controls the moving part 121 to move in the direction close to the bottom wall 1122, and the elastic membrane 111 is deformed under pressure to form the curved surface. The control module 20 also controls and adjusts the distance that the moving part 121 moves in the direction close to the bottom wall 1122, thereby adjusting the deformation degree of the elastic membrane 111 and adjusting the curvature radius of the formed curved surface, thereby adjusting the focal length of the ultrasonic wave output by the ultrasonic output component 13.

[0034] By controlling the movable member 121 to move in a direction close to the bottom wall 1122, the elastic membrane 111 is deformed by force to form the curved surface. The formed curved surface can focus the ultrasonic wave output by the ultrasonic output component 13, and by controlling and adjusting the moving distance of the movable member 121, the force applied to the elastic membrane 111 can be adjusted, and then the deformation degree of the elastic membrane 111 can be adjusted, thereby adjusting the focal length of the ultrasonic wave.

[0035] See also Figures 2 to 4 , Figure 3 This is a schematic diagram of the planar structure of the moving member 121 and the elastic membrane 111 provided in one embodiment of the present application. Figure 4 FIG. 1 is a schematic diagram of a planar structure of a moving member 121 and an elastic membrane 111 provided in another embodiment of the present application. Figures 2 to 4 As shown, the movable member 121 is annular and is attached to the side of the elastic membrane 111 away from the bottom wall 1122, and the ultrasonic output component 13 is arranged on the side of the bottom wall 1122 away from the opening 1121. The ultrasonic output component 13 is used to output ultrasonic waves to the portion of the elastic membrane 111 opposite to the surrounding space 1211 of the movable member 121, wherein the portion of the elastic membrane 111 opposite to the surrounding space 1211 of the movable member 121 is the portion of the elastic membrane 111 surrounded by the orthographic projection of the movable member 121 on the elastic membrane 111.

[0036] The piezoelectric vibrator of the ultrasonic output component 13 is disposed on a side of the bottom wall 1122 away from the opening 1121 . In some embodiments, the orthographic projection of the piezoelectric vibrator on the moving member 121 at least covers the surrounding space 1211 of the moving member 121 .

[0037] The moving member 121 may be bonded to the elastic membrane 111 , for example, by bonding to a side of the elastic membrane 111 away from the bottom wall 1122 through double-sided adhesive, laser adhesive, etc.

[0038] The moving member 121 may be in the form of a closed ring (eg Figure 3 and Figure 4 The shape of the moving member 121 can be circular (as shown in FIG. Figure 3 As shown), rectangle (as Figure 4 It can also be set to any other shape according to actual needs.

[0039] See also Figure 5 and Figure 6 , Figure 5 This is a schematic diagram of an elastic film 111 provided in an embodiment of the present application that is deformed to form a curved surface. Figure 6 Schematic diagram of the elastic membrane 111 deformed to form a curved surface according to another embodiment of the present application. In some embodiments, the control module 20 controls the moving member 121 to move in a direction close to the bottom wall 1122, and the portion of the elastic membrane 111 opposite to the surrounding space 1211 of the moving member 121 bulges in a direction away from the bottom wall 1122 to form the curved surface 111a (such as Figure 5 and Figure 6 As shown in FIG. 1 ), the control module 20 controls and adjusts the distance that the moving member 121 moves in the direction close to the bottom wall 1122, thereby adjusting the deformation degree of the portion of the elastic membrane 111 that is opposite to the surrounding space 1211 of the moving member 121 and adjusting the curvature radius of the formed curved surface 111a, thereby adjusting the focal length of the ultrasonic wave output by the ultrasonic output component 13. The initial shape of the elastic membrane 111, that is, when it is not deformed, is as shown in FIG. Figure 2 As shown, after the moving member 121 is controlled to move in a direction close to the bottom wall 1122, the portion of the elastic membrane 111 opposite to the surrounding space 1211 of the moving member 121 bulges in a direction away from the bottom wall 1122 to form the curved surface 111a. Figure 5 and Figure 6 In this embodiment, the curved surface 111a is a convex surface.

[0040] Among them, within a certain range of moving distance, the distance that the moving member 121 moves in the direction close to the bottom wall 1122 is negatively correlated with the radius of curvature of the curved surface 111a, that is, the greater the distance that the moving member 121 moves in the direction close to the bottom wall 1122, the smaller the radius of curvature of the curved surface 111a, the smaller the distance that the moving member 121 moves in the direction close to the bottom wall 1122, and the larger the radius of curvature of the curved surface 111a; the radius of curvature of the curved surface 111a is positively correlated with the focal length of the ultrasonic wave output by the ultrasonic output component 13, that is, the greater the radius of curvature of the curved surface 111a, the greater the focal length of the ultrasonic wave output by the ultrasonic output component 13, and the smaller the radius of curvature of the curved surface 111a, the smaller the focal length of the ultrasonic wave output by the ultrasonic output component 13. It can be understood that within a certain range of moving distance, the distance that the moving member 121 moves in the direction close to the bottom wall 1122 is negatively correlated with the focal length of the ultrasonic wave output by the ultrasonic output component 13.

[0041] in, Figure 6 Compared to Figure 5 The moving member 121 moves a greater distance in the direction close to the bottom wall 1122. Figure 6 The focus in Figure 5 The focal point is closer to the bottom wall 1122, Figure 6 The focal length is less than Figure 5 The focal length in.

[0042] By setting the movable member 121 to be annular and controlling the movable member 121 to move in a direction close to the bottom wall 1122, the portion of the elastic membrane 111 opposite to the surrounding space 1211 of the movable member 121 is deformed under the extrusion of the fluid 113 to form the curved surface 111a. The formed curved surface 111a and the fluid 113 can constitute a lens to focus the ultrasonic wave output by the ultrasonic output component 13. In addition, by controlling and adjusting the moving distance of the movable member 121, the degree of extrusion of the portion of the elastic membrane 111 opposite to the surrounding space 1211 of the movable member 121 can be adjusted, and then the degree of deformation of the portion of the elastic membrane 111 opposite to the surrounding space 1211 of the movable member 121 can be adjusted, so that the refraction angle of the formed lens to the transmitted ultrasonic wave can be adjusted to adjust the focal length of the ultrasonic wave.

[0043] In some embodiments, Figure 2 , Figure 5 and Figure 6As shown, the driving assembly 12 further includes a permanent magnet 122 fixed to the accommodating cavity 112, and the moving member 121 can generate a magnetic field after being energized. The control module 20 controls the moving member 121 to be energized, and the moving member 121 and the permanent magnet 122 attract each other after being energized and move in a direction close to the bottom wall 1122.

[0044] The permanent magnet 122 is fixed to the accommodating cavity 112, and the control module 20 outputs an electrical signal to the moving member 121 to energize the moving member 121. After energization, the moving member 121 generates a magnetic field, and there is a magnetic attraction between the moving member 121 and the permanent magnet 122. The moving member 121 and the permanent magnet 122 attract each other, and the moving member 121 moves in a direction close to the bottom wall 1122. When the control module 20 stops outputting an electrical signal to the moving member 121, the moving member 121 moves in a direction away from the bottom wall 1122, so that the elastic membrane 111 returns to its initial state.

[0045] The magnetic field strength of the magnetic field generated by the moving member 121 can be controlled and adjusted by controlling and adjusting the electrical signal output to the moving member 121, so as to control and adjust the magnetic attraction between the moving member 121 and the permanent magnet 122, and further control and adjust the distance that the moving member 121 moves in the direction close to the bottom wall 1122. For example, the magnetic field strength of the magnetic field generated by the moving member 121 can be controlled and adjusted by controlling and adjusting the magnitude of the current supplied to the moving member 121.

[0046] The moving part 121 may include an electromagnetic coil and a heat-resistant column, the electromagnetic coil is wound around the heat-resistant column, and the electromagnetic coil can generate a magnetic field by energizing the electromagnetic coil.

[0047] In some embodiments, the permanent magnet 122 is annular in shape, so that the permanent magnet 122 has the same or similar shape as the moving member 121 , which is beneficial for the moving member 121 and the permanent magnet 122 to attract each other.

[0048] like Figure 2 , Figure 5 and Figure 6 As shown, the accommodating cavity 112 includes a side wall 1123, the permanent magnet 122 is arranged on the side wall 1123 and fixedly connected to the side wall 1123, and / or the permanent magnet 122 is arranged on the bottom wall 1122 and fixedly connected to the bottom wall 1122, and the orthographic projection of the ultrasonic output component 13 on the permanent magnet 122 is located inside the permanent magnet 122.

[0049] The driving component 12 may include one or at least two permanent magnets 122 .

[0050] The permanent magnet 122 may be disposed on the inner peripheral wall of the accommodating cavity 112 , or may be disposed on the outer peripheral wall of the accommodating cavity 112 .

[0051] In other embodiments, Figure 5 and Figure 6 As shown, a hole is provided inside the side wall 1123 of the accommodating cavity 112, and the permanent magnet 122 is arranged in the hole.

[0052] In other embodiments, the side wall 1123 of the accommodating cavity 112 may be provided with a groove along a direction perpendicular to the bottom wall 1122, and the groove extends from the end of the side wall 1123 close to the opening 1121 to a position of the side wall 1123 close to the bottom wall 1122, and the permanent magnet 122 is embedded in the groove.

[0053] See also Figure 7 , is a schematic diagram of a permanent magnet 122 provided in an embodiment of the present application being disposed on a bottom wall 1122. In some embodiments, the permanent magnet 122 is disposed on the bottom wall 1122, and the permanent magnet 122 is disposed on a side of the bottom wall 1122 close to the opening 1121 and / or a side of the bottom wall 1122 away from the opening 1121 (e.g. Figure 7 shown).

[0054] In some embodiments, the permanent magnet 122 is parallel to the moving member 121, and the center of the permanent magnet 122 is coaxial with the center of the moving member 121, that is, the center point of the orthographic projection of the permanent magnet 122 on the moving member 121 coincides with the center point of the moving member 121. In other embodiments, the permanent magnet 122 and the moving member 121 may not be parallel, and the permanent magnet 122 and the moving member 121 may be staggered, that is, the center point of the orthographic projection of the permanent magnet 122 on the moving member 121 does not coincide with the center point of the moving member 121.

[0055] In some embodiments, Figure 2 , Figures 5 to 7 As shown, the bottom wall 1122 includes an acoustic impedance matching layer 1122a, and the ultrasonic output component 13 is attached to a side of the acoustic impedance matching layer 1122a away from the opening 1121, and the acoustic impedance matching layer 1122a is at least used to prevent the reflection of the ultrasonic wave output by the ultrasonic output component 13. The piezoelectric vibrator of the ultrasonic output component 13 is attached to a side of the acoustic impedance matching layer 1122a away from the opening 1121.

[0056] The material of the acoustic impedance matching layer 1122a may include at least one of epoxy resin, polyurethane, polystyrene, polyoxymethylene, and polyetherketone. The material of the acoustic impedance matching layer 1122a may also include other types of materials that can be used to make an acoustic impedance matching layer.

[0057] In other embodiments, the ultrasonic output assembly 13 is arranged on a side of the elastic membrane 111 away from the bottom wall 1122 and is spaced from the elastic membrane 111, and the ultrasonic output assembly 13 is used to output ultrasonic waves to the portion of the elastic membrane 111 located between the side wall 1123 and the outer peripheral side of the moving member 121. The control module 20 controls the moving member 121 to move in a direction close to the bottom wall 1122, and the portion of the elastic membrane 111 located between the side wall 1123 and the outer peripheral side of the moving member 121 is recessed in a direction close to the bottom wall 1122 to form the curved surface 111a, and the control module 20 controls and adjusts the distance that the moving member 121 moves in a direction close to the bottom wall 1122, thereby controlling and adjusting the deformation degree of the portion of the elastic membrane 111 located between the side wall 1123 and the outer peripheral side of the moving member 121 to adjust the curvature radius of the formed curved surface 111a, and then adjusting the focal length of the ultrasonic wave output by the ultrasonic output assembly 13. The piezoelectric vibrator of the ultrasonic output component 13 is disposed on a side of the elastic membrane 111 away from the bottom wall 1122 and is spaced apart from the elastic membrane 111. In this embodiment, the curved surface 111a is a concave surface.

[0058] The elastic film 111 includes a film body and a reflective layer, and the reflective layer is attached to the side of the film body away from the bottom wall 1122. The material of the reflective layer may include a metal material, such as aluminum, titanium, etc., and the reflective layer can be formed on the film body by metal plating, such as vacuum evaporation, vacuum sputtering, and vacuum ion plating. The piezoelectric vibrator of the ultrasonic output component 13 is arranged on the side of the reflective layer away from the bottom wall 1122 and is spaced from the reflective layer. When the ultrasonic wave output by the ultrasonic output component 13 reaches the reflective layer, it is reflected by the reflective layer to a direction different from the incident direction and focused.

[0059] Among them, the greater the distance that the movable member 121 moves in the direction close to the bottom wall 1122, the smaller the curvature radius of the curved surface 111a, and the smaller the focal length of the ultrasonic wave output by the ultrasonic output component 13; the smaller the distance that the movable member 121 moves in the direction close to the bottom wall 1122, the greater the curvature radius of the curved surface 111a, and the greater the focal length of the ultrasonic wave output by the ultrasonic output component 13.

[0060] By controlling the moving member 121 to move in a direction close to the bottom wall 1122, the portion of the elastic membrane 111 located between the side wall 1123 and the outer peripheral side of the moving member 121 is deformed by the force of the moving member 121 to form the curved surface 111a. At this time, the formed curved surface 111a can be used as an acoustic reflector to reflect and focus the ultrasonic wave output by the ultrasonic output component 13, and by controlling and adjusting the moving distance of the moving member 121, the size of the force applied to the elastic membrane 111 can be adjusted, and then the curvature radius of the formed curved surface 111a can be adjusted, so that the reflection angle of the formed acoustic reflector to the ultrasonic wave can be adjusted to adjust the focal length of the ultrasonic wave.

[0061] In some embodiments, the ultrasonic output component 13 is disposed on a side of the elastic membrane 111 away from the bottom wall 1122 and spaced from the elastic membrane 111, and the ultrasonic output component 13 is used to output ultrasonic waves to the portion of the elastic membrane 111 opposite to the surrounding space 1211 of the moving member 121. The control module 20 controls the moving member 121 to move in a direction away from the bottom wall 1122, and the portion of the elastic membrane 111 opposite to the surrounding space 1211 of the moving member 121 is recessed in a direction close to the bottom wall 1122 to form the curved surface 111a, and the control module 20 controls and adjusts the distance that the moving member 121 moves in a direction away from the bottom wall 1122, thereby controlling and adjusting the deformation degree of the portion of the elastic membrane 111 opposite to the surrounding space 1211 of the moving member 121 to adjust the curvature radius of the formed curved surface 111a, and further adjusting the focal length of the ultrasonic wave output by the ultrasonic output component 13. The piezoelectric vibrator of the ultrasonic output component 13 is disposed on a side of the elastic membrane 111 away from the bottom wall 1122 and is spaced apart from the elastic membrane 111. In this embodiment, the curved surface 111a is a concave surface.

[0062] In this embodiment, the elastic film 111 includes a film body and a reflective layer, and the reflective layer is attached to the side of the film body away from the bottom wall 1122. The material of the reflective layer may include a metal material, such as aluminum, titanium, etc., and the reflective layer can be formed on the film body by metal plating, such as vacuum evaporation, vacuum sputtering, and vacuum ion plating. The piezoelectric vibrator of the ultrasonic output component 13 is arranged on the side of the reflective layer away from the bottom wall 1122 and is spaced from the reflective layer. When the ultrasonic wave output by the ultrasonic output component 13 reaches the reflective layer, it is reflected by the reflective layer to a direction different from the incident direction and focused.

[0063] By controlling the moving member 121 to move in a direction away from the bottom wall 1122, the elastic membrane 111 is driven to move in a direction away from the bottom wall 1122, so that the pressure on the surface of the elastic membrane 111 away from the bottom wall 1122 is greater than the pressure on the surface of the elastic membrane 111 facing the bottom wall 1122, so that the part of the elastic membrane 111 opposite to the surrounding space 1211 of the moving member 121 is recessed in a direction close to the bottom wall 1122 to form the curved surface 111a. At this time, the formed curved surface 111a can be used as an acoustic reflector to reflect and focus the ultrasonic wave output by the ultrasonic output component 13, and by controlling and adjusting the moving distance of the moving member 121, the pressure difference between the two relative surfaces of the elastic membrane 111 can be adjusted, and then the curvature radius of the formed curved surface 111a can be adjusted, so that the reflection angle of the formed acoustic reflector to the ultrasonic wave can be adjusted to adjust the focal length of the ultrasonic wave.

[0064] As mentioned above, the accommodating cavity 112 includes a bottom wall 1122, and the bottom wall 1122 is opposite to the opening 1121. In some embodiments, the driving component 12 includes a liquid extraction component, which is in communication with the accommodating cavity 112 and is used to extract the fluid 113 in the accommodating cavity 112. The ultrasonic output component 13 is disposed on a side of the elastic membrane 111 away from the bottom wall 1122 and is spaced apart from the elastic membrane 111. The ultrasonic output component 13 is used to output ultrasonic waves to the elastic membrane 111. The piezoelectric vibrator of the ultrasonic output component 13 is disposed on a side of the elastic membrane 111 away from the bottom wall 1122 and is spaced apart from the elastic membrane 111.

[0065] The control module 20 is used to control the liquid extraction component to extract the fluid in the accommodating cavity 112, so that the pressure in the accommodating cavity 112 is less than the external pressure of the accommodating cavity 112, and the elastic membrane 111 is deformed by pressure and concave in the direction close to the bottom wall 1122 to form the curved surface 111a. The control module 20 is also used to control and adjust the amount of the fluid 113 extracted from the accommodating cavity 112 by the liquid extraction component, thereby controlling and adjusting the deformation degree of the elastic membrane 111 to adjust the curvature radius of the curved surface 111a formed, and further adjusting the focal length of the ultrasonic wave output by the ultrasonic output component 13. In this embodiment, the curved surface 111a is a concave surface.

[0066] Among them, the liquid extraction component may include a pump body, an infusion tube and a liquid storage device, the infusion tube is connected to the liquid storage device and the accommodating cavity 112 respectively, and the pump body is used to squeeze the infusion tube so that the fluid 113 in the accommodating cavity 112 flows toward the liquid storage device, thereby extracting the fluid 113 in the accommodating cavity 112 and making it flow into the liquid storage device.

[0067] In this embodiment, the elastic film 111 includes a film body and a reflective layer, and the reflective layer is attached to the side of the film body away from the bottom wall 1122. The material of the reflective layer may include a metal material, such as aluminum, titanium, etc., and the reflective layer can be formed on the film body by metal plating, such as vacuum evaporation, vacuum sputtering, and vacuum ion plating. The piezoelectric vibrator of the ultrasonic output component 13 is arranged on the side of the reflective layer away from the bottom wall 1122 and is spaced from the reflective layer. When the ultrasonic wave output by the ultrasonic output component 13 reaches the reflective layer, it is reflected by the reflective layer to a direction different from the incident direction and focused.

[0068] By extracting the fluid 113 in the accommodating cavity 112, the pressure on the surface of the elastic membrane 111 facing away from the bottom wall 1122 is greater than the pressure on the surface of the elastic membrane 111 facing the bottom wall 1122, thereby causing the elastic membrane 111 to be recessed in a direction close to the bottom wall 1122 to form the curved surface 111a. At this time, the formed curved surface 111a can be used as an acoustic reflector to reflect and focus the ultrasonic wave output by the ultrasonic output component 13, and by controlling and adjusting the amount of the extracted fluid 113, the pressure difference between the two relative surfaces of the elastic membrane 111 can be adjusted, thereby adjusting the curvature radius of the formed curved surface 111a, thereby adjusting the reflection angle of the formed acoustic reflector to the ultrasonic wave to adjust the focal length of the ultrasonic wave.

[0069] In some embodiments, the driving component 12 includes an infusion component, which is in communication with the accommodating cavity 112 and is used to input fluid into the accommodating cavity 112. The ultrasonic output component 13 is disposed on a side of the bottom wall 1122 away from the opening 1121, and is used to output ultrasonic waves to the elastic membrane 111. The piezoelectric vibrator of the ultrasonic output component 13 is disposed on a side of the bottom wall 1122 away from the opening 1121.

[0070] The infusion component may be the same as the extraction component, that is, the fluid 113 in the accommodating cavity 112 may be extracted through the extraction component, and the fluid 113 may also be input into the accommodating cavity 112 .

[0071] The control module 20 is used to control the infusion component to input the fluid 113 into the accommodating cavity 112, the elastic membrane 111 is deformed under pressure and bulges in a direction away from the bottom wall 1122 to form the curved surface 111a, and the control module 20 is also used to control and adjust the amount of the fluid 113 input into the accommodating cavity 112 by the infusion component, thereby controlling and adjusting the deformation degree of the elastic membrane 111 to adjust the curvature radius of the formed curved surface 111a, and further adjusting the focal length of the ultrasonic wave output by the ultrasonic output component 13. In this embodiment, the curved surface 111a is a convex surface.

[0072] When the infusion component inputs fluid 113 into the accommodating cavity 112, the fluid 113 in the accommodating cavity 112 will squeeze the elastic membrane 111 to cause it to bulge in a direction away from the bottom wall 1122 to form a curved surface 111a, so that the infusion component can drive the elastic membrane 111 to deform to form the curved surface 111a.

[0073] Among them, the more the amount of fluid 113 input into the accommodating cavity 112, the smaller the curvature radius of the formed curved surface 111a, and the smaller the focal length of the ultrasonic wave output by the ultrasonic output component 13; the less the amount of fluid 113 input into the accommodating cavity 112, the larger the curvature radius of the formed curved surface 111a, and the larger the focal length of the ultrasonic wave output by the ultrasonic output component 13.

[0074] By inputting the fluid 113 into the accommodating cavity 112, the elastic membrane 111 is deformed under the compression of the fluid 113 to form the curved surface 111a. The formed curved surface 111a and the fluid 113 can constitute a lens to focus the ultrasonic wave output by the ultrasonic output component 13, and by controlling the amount of the input fluid 113, the degree of compression of the elastic membrane 111 can be adjusted, and then the degree of deformation of the elastic membrane 111 can be adjusted, so that the refraction angle of the formed lens to the transmitted ultrasonic wave can be adjusted to adjust the focal length of the ultrasonic wave.

The control module 20 is further configured to obtain a target focal length value, determine a target moving distance value of the moving member 121 according to the target focal length value, and control the moving member 121 to move the target moving distance value in a direction close to the bottom wall 1122, so that the focal length of the ultrasonic wave output by the ultrasonic output component 13 is the target focal length value.

[0076] By acquiring the target focal length value and controlling the movement of the moving member 121 according to the target focal length value, the adjustment requirement of the output depth of the ultrasonic wave can be met in time, so as to improve the efficiency of ultrasonic beauty.

[0077] The control module 20 may determine the target distance value corresponding to the target focal length value according to the preset correspondence between the preset focal length value and the moving distance value, wherein the preset correspondence between the focal length value and the moving distance value includes a correspondence between at least two focal length values ​​and at least two moving distance values, and each focal length value corresponds to a moving distance value. The preset correspondence between the focal length value and the moving distance value may be pre-stored in the memory of the ultrasonic beauty instrument 100.

[0078] In some embodiments, the control module 20 acquires the target focal length value, which may include: acquiring the target focal length value in response to a setting operation of the focal length value.

[0079] Specifically, the ultrasonic beauty instrument 100 may include a display screen, which is provided with a focal value setting operation interface for performing a focal value setting operation to obtain the target focal value. The user can input the target focal value on the focal value setting operation interface, and the control module 20 responds to the user's operation and obtains the target focal value.

[0080] In other embodiments, the ultrasonic beauty instrument 100 is provided with at least two ultrasonic focal length gears, each of which corresponds to a focal length value. The control module 20 acquires the target focal length value, which may include: generating an ultrasonic focal length gear adjustment signal in response to an ultrasonic focal length gear adjustment operation; and determining the target focal length value according to the ultrasonic focal length gear adjustment signal.

[0081] The ultrasonic beauty instrument 100 includes at least two ultrasonic focal length gear buttons, and the user can adjust the ultrasonic focal length gear by pressing the ultrasonic focal length gear button.

[0082] In some embodiments, the control module 20 is used to determine the target magnetic field strength value corresponding to the target moving distance value according to the correspondence between the preset moving distance value and the magnetic field strength value, and control the moving member 121 to generate a magnetic field with the target magnetic field strength value, so that there is a target magnetic attraction between the moving member 121 and the permanent magnet 122, so that the moving member 121 and the permanent magnet 122 are attracted to each other under the action of the target magnetic attraction, and move the target moving distance value in the direction close to the bottom wall 1122. The control module 20 is also used to control the ultrasonic output component 13 to output ultrasonic waves when the moving member 121 moves the target moving distance value in the direction close to the bottom wall 1122.

[0083] The correspondence between the moving distance value and the magnetic field strength value can be pre-stored in the memory of the ultrasonic beauty instrument 100. The correspondence between the moving distance value and the magnetic field strength value includes a correspondence between at least two moving distance values ​​and at least two magnetic field strength values, and each moving distance value corresponds to a magnetic field strength value.

[0084] Among them, the control module 20 can control the output of a corresponding electrical signal to the moving part 121 according to the determined target magnetic field strength value, so that the moving part 121 generates a magnetic field with the target magnetic field strength value, and the moving part 121 and the permanent magnet 122 have the target magnetic attraction force.

[0085] In some embodiments, the ultrasonic beauty instrument 100 further includes a distance sensor, which is disposed on a side of the moving member 121 away from the elastic membrane 111, and is used to detect the moving distance value of the moving member 121. The distance sensor may include an infrared distance sensor, a laser distance sensor, and the like.

[0086] The control module 20 is used to control the distance sensor to detect the moving distance value of the moving member 121 after controlling the moving member 121 to move the target moving distance value in the direction close to the bottom wall 1122, and when the moving distance value detected by the distance sensor is different from the target moving distance value, control and adjust the moving member 121 to move in the direction close to or away from the bottom wall 1122 until the moving distance value detected by the distance sensor is the same as the target moving distance value.

[0087] Among them, the distance sensor can detect the distance value between the moving part 121 and other structures, for example, detect the distance value between the moving part 121 and the inner wall of the shell of the ultrasonic beauty instrument 100, and then detect the moving distance value of the moving part 121. Specifically, before the moving part 121 moves in the direction close to the bottom wall 1122, the distance value S1 between the moving part 121 and the inner wall of the shell of the ultrasonic beauty instrument 100 is detected. After controlling the moving part 121 to move the target moving distance value in the direction close to the bottom wall 1122, the distance value S2 between the moving part 121 and the inner wall of the shell of the ultrasonic beauty instrument 100 is detected, and then the actual moving distance value, i.e., S2-S1, is obtained. The control module 20 can compare the actual moving distance value with the target moving distance value, and when the actual moving distance value is less than the target moving distance value, control the moving member 121 to move in a direction close to the bottom wall 1122; when the actual moving distance value is greater than the target moving distance value, control the moving member 121 to move in a direction away from the bottom wall 1122; when the actual moving distance value is equal to the target moving distance value, control the moving member 121 to stay at the current position.

[0088] After controlling the moving member 121 to move the target moving distance value in the direction close to the bottom wall 1122, by detecting the moving distance value of the moving member 121 and judging whether to fine-tune the moving distance of the moving member 121 according to the detected moving distance value, the moving distance of the moving member 121 can be precisely adjusted to the target moving distance value, so that the focal length value of the ultrasonic wave output by the ultrasonic output component 13 can be precisely adjusted to the target focal length value.
