Detailed Implementation

[0023] The embodiments of the present invention are described in detail below. The embodiments described with reference to the accompanying drawings are exemplary. The embodiments of the present invention are described in detail below.

[0024] To address the aforementioned problems, a first aspect of the present invention provides a method for controlling an electrode assembly. This method enables dynamic adjustment of the electrode head's movement speed, thereby maximizing its cosmetic effects.

[0025] The following is for reference. Figure 1 The control method of the electrode assembly according to an embodiment of the present invention is described, with reference to Figure 1 As shown, the control method includes at least steps S1-S2.

[0026] Step S1: Determine the working status of the electrode assembly.

[0027] Specifically, the operating state can be determined based on changes in the external environment of the electrode assembly, or it can be determined based on changes in the internal environment of the electrode assembly, such as the electrode tip; there are no restrictions on this.

[0028] For example, the electrode assembly can be integrated into a beauty device that can be configured with multiple beauty modes. The operational requirements of the electrode assembly differ in each beauty mode, so the operational status of the electrode assembly can be determined based on the beauty mode. Alternatively, the operational status of the electrode assembly can include the current position information of its internal electrode heads, which can be obtained in real time by setting up a position sensor.

[0029] Step S2: Adjust the moving speed of the electrode assembly based on the working status.

[0030] Specifically, different movement speeds result in different cosmetic effects. For example, when the electrode assembly uses an electromagnetic drive to reciprocate the electrode head, the generation of electromagnetic fields and the repulsion and attraction of like charges result in a very rapid response. Therefore, the reciprocating motion of the electrode head in this way is too fast. However, for functions like beauty masks, which require slow movement to allow the radio frequency electrode head to effectively heat up, the effectiveness will be greatly reduced. Therefore, this application dynamically adjusts the movement speed of the electrode assembly based on changes in the working state of the electrode assembly. Compared to the electrode assembly moving at a single fixed speed, this method can achieve precise control of the electrode assembly, avoiding the problem of the electrode assembly affecting the cosmetic effect due to excessively fast or slow movement. This is beneficial for meeting different cosmetic needs and achieving the goal of fully exerting the cosmetic effect under different cosmetic functions.

[0031] In some embodiments, the operating state includes the current position information of the electrode assembly, and adjusting the moving speed of the electrode assembly based on the operating state includes: adjusting the moving speed of the electrode assembly based on the current position information.

[0032] Specifically, based on the movable setting of the electrode head within a limited area, for beauty care devices, this limited area can be associated with the beauty area. Different beauty areas require different moving speeds of the electrode components. Therefore, the moving speed of the electrode components can be adaptively adjusted based on the current position information of the electrode components, thereby achieving precise control of the electrode components and improving the beauty effect within the limited area.

[0033] For example, taking a beauty mask as an example, the defined area can include multiple sub-regions, such as a first sub-region on the beauty mask corresponding to the user's cheek and a second sub-region on the beauty mask corresponding to the user's nose. If the current position information is determined to be within the first sub-region, the moving speed of the electrode component can be adjusted to a first speed to meet the beauty effect of the cheek; if the current position information is determined to be within the second sub-region, the moving speed of the electrode component can be adjusted to a second speed to meet the beauty effect of the nose. This achieves precise control of the moving speed of the electrode component at different positions, improving the beauty effect. The first and second speeds can be fixed values, meaning the moving speed of the electrode component within the corresponding area remains constant; or, the first and second speeds can be variables, meaning the moving speed of the electrode component within the corresponding area can change linearly or non-linearly. For example, different users have different physiological states in different areas. Based on the current position information, the actual physiological state of different areas can be identified, and the moving speed of the electrode component within that area can be dynamically adjusted based on the actual physiological state of the corresponding area, thereby further improving the beauty effect and meeting the personalized beauty needs of different users.

[0034] In some embodiments, the electrode assembly includes an electrode head and a plurality of coils, at least two of which have currents in opposite directions, and the ends of the coils facing the electrode head have opposite polarities. The coils with currents in opposite directions drive the electrode head to move within a defined area.

[0035] For example, consider the integration of electrode components into a beauty mask, such as... Figures 2-4 As shown, the beauty mask 100 includes: a mask housing 10, a first circuit board 20, and at least one electrode assembly 30.

[0036] The mask housing 10 includes a first housing 11 and a second housing 12, which define an installation cavity. The second housing 12 is used to contact the human face. A first circuit board 20 is disposed between the first housing 11 and the second housing 12. An electrode assembly 30 is connected to the mask housing 10. At least a portion of the electrode assembly 30 protrudes from the surface of the second housing 12 away from the first housing 11. The electrode assembly 30 includes a plurality of coils 31 and an electrode head 32. The plurality of coils 31 are respectively connected to the first circuit board 20. The electrode head 32 has multiple movement positions. At least two of the plurality of coils 31 have opposite currents. The ends of the plurality of coils 31 facing the electrode head 32 have opposite polarities. The coils 31 with opposite currents drive the electrode head 32 to move between the multiple movement positions.

[0037] The shape of the mask housing 10 is adapted to the human face. The mask housing 10 includes a first housing 11 and a second housing 12 disposed opposite to each other along the thickness direction of the beauty mask 100. The first housing 11 is disposed on the side of the second housing 12 away from the human face. The surface of the second housing 12 away from the first housing 11 is adapted to contact the human face. The first circuit board 20 is disposed between the first housing 11 and the second housing 12 along the thickness direction of the beauty mask 100. The first housing 11 and the second housing 12 together define a mounting cavity. The electrode assembly 30 is disposed in the mounting cavity, and the electrode assembly 30 protrudes from the surface of the second housing 12 away from the first housing 11 along the thickness direction of the beauty mask 100. In this application, the electrode head 32 is a radio frequency electrode head 32. The electrode head 32 has two movement positions spaced apart along the height direction of the beauty mask 100. The electrode assembly 30 includes two coils 31 spaced apart along the height direction of the beauty mask 100 and the electrode head 32. The first circuit board 20 is electrically connected to the two coils 31, thereby energizing the two coils 31. The currents of the two coils 31 spaced apart along the height direction of the beauty mask 100 are opposite, and the polarities of the ends of the two coils 31 facing the electrode head 32 are opposite. The two coils 31 can drive the electrode head 32 to move between the two movement positions along the height direction of the beauty mask 100. Therefore, by setting multiple coils 31 within the electrode assembly 30, with at least two coils 31 having opposite currents, the coils 31 with opposite currents drive the electrode head 32 to move between multiple positions, thereby flexibly adjusting the radio frequency position of the electrode head 32, improving the adaptability and flexibility of the beauty mask 100, increasing the treatment area of ​​the electrode assembly 30, effectively improving the treatment effect of the beauty mask 100, improving the reliability of the beauty mask 100, and enhancing the user experience.

[0038] Based on the above example of setting up electrode components, the operating principle of the electrode head is to achieve polarity switching of the coil in the circuit through Ampere's law, and to achieve vertical sliding of the electrode component by repelling the polarity of the magnet inside the electrode component using the principle of polarity repulsion. Therefore, in this application, adjusting the moving speed of the electrode component based on the working state includes: adjusting the current state of at least one coil based on the current position information of the electrode head to change the moving speed of the electrode head.

[0039] In some embodiments, the current state includes at least one or more of the current magnitude and current direction. Other state parameters besides the two mentioned above, such as the rate of change of current, may also be introduced without limitation. Specifically, since the magnitude of the coil current directly affects the magnitude of the magnetic force—the larger the current, the stronger the magnetic force—the speed of the electrode head can be effectively controlled. Furthermore, based on Ampere's law, when the current direction changes, the coil polarity also changes, thereby causing the electrode head to reciprocate. Therefore, based on the above principles, this application adjusts the current state of at least one coil to change the moving speed of the electrode head under different positional information, thereby achieving precise control of the electrode head and maximizing its cosmetic effects.

[0040] For example, regarding the direction of current, refer to Figure 5 The circuit shown can be used for control, and selective conduction of local circuits can be achieved through MOSFETs. When MOSFETs M1 and M4 are turned on, the current flows from the positive terminal to the negative terminal, which provides positive current to at least one coil. When MOSFETs M2 and M3 are turned on, the current flows from the negative terminal to the positive terminal, which provides positive current to at least one coil. This achieves control over the change in current flow direction.

[0041] In some embodiments, the current location information includes at least one or more of the direction of movement of the electrode head and the current position of the electrode head within the defined area.

[0042] In some embodiments, the plurality of coils includes a first coil group and a second coil group, the ends of the first coil group and the second coil group having opposite polarities adjacent to the electrode head, and the electrode head moving within a defined region between the first coil group and the second coil group. Specifically, as shown... Figure 3 As shown, the plurality of coils 31 include a first coil group 311 and a second coil group 312, the first coil group 311 and the second coil group 312 having opposite polarities at one end adjacent to the electrode head 32; the electrode head 32 includes an electrode head housing and a magnetic element, the magnetic element being disposed inside the electrode head housing, and the magnetic element moving between the first coil group 311 and the second coil group 312.

[0043] In this application, each electrode assembly 30 includes a first coil group 311 and a second coil group 312 spaced apart along the height direction of the beauty mask 100. Each first coil group 311 and second coil group 312 includes two sub-coils 313 spaced apart along the width direction of the beauty mask 100. The polarities of the ends of the first coil group 311 and the second coil group 312 adjacent to the electrode head 32 along the thickness direction of the beauty mask 100 are opposite. The electrode head 32 includes an electrode head housing and a magnetic component. The electrode head housing forms a receiving cavity, and the magnetic component is disposed within the receiving cavity. By adjusting the direction of the current flowing through the sub-coils 313 in the first coil group 311 and the second coil group 312, the polarity of the ends of the first coil group 311 and the second coil group 312 adjacent to the electrode head 32 is switched using Ampere's law. Utilizing the principle of like polarity repulsion, i.e., the magnetic component 34 repels the sub-coils 313 of the same polarity, the magnetic component moves between the first coil group 311 and the second coil group 312 along the height direction of the beauty mask 100.

[0044] Therefore, by placing the magnetic component inside the electrode head housing, and having the polarities of the first coil group 311 and the second coil group 312 opposite at their adjacent ends to the electrode head 32, the direction of current flow through the first coil group 311 and the second coil group 312 can be adjusted. That is, by utilizing the Ampere's law and the principle of like polarity repulsion, the magnetic component can be driven to move between the first coil group 311 and the second coil group 312, thereby allowing the electrode head 32 to move between the first coil group 311 and the second coil group 312. This enables flexible adjustment of the radio frequency position of the electrode head 32, improving the adaptability and flexibility of the beauty mask 100.

[0045] Based on the design of the first and second coil groups described above, this application provides a method for adjusting the current state of at least one coil based on current position information to change the moving speed of the electrode head. This includes: when the moving direction is determined to be towards the second coil group, providing a positive current to both the first and second coil groups, adjusting the current state of the first coil group to a first current, and adjusting the current of the second coil group to a second current, so that the moving speed of the electrode head is a first target speed, wherein the first current is less than the second current; when the moving direction is determined to be towards the first coil group, providing a reverse current to both the first and second coil groups, adjusting the current of the first coil group to a third current, and adjusting the current of the second coil group to a fourth current, so that the moving speed of the electrode head is a second target speed, wherein the third current is less than the fourth current. Thus, by adjusting the current state in the above manner, the moving speed and direction of the electrode head are indirectly changed, effectively achieving the purpose of the electrode head reciprocating between the two coil groups.

[0046] Among these, the first current and the third current can be the same or different values, the second current and the fourth current can be the same or different values, and the first target velocity and the second target velocity can be the same or different values; there are no restrictions on these.

[0047] In some embodiments, the method of this application further includes: determining the current moving speed of the electrode head during the movement of the electrode head; if the current moving speed is determined to be greater than a first target speed, adjusting the current of the second coil group to a fifth current, where the fifth current is less than the second current; if the current moving speed is determined to be less than the first target speed, adjusting the current of the first coil group to a sixth current, where the sixth current is less than the first current; if the current moving speed is determined to be greater than a second target speed, adjusting the current of the second coil group to a seventh current, where the seventh current is less than the second current; and if the current moving speed is determined to be less than the second target speed, adjusting the current of the first coil group to an eighth current, where the eighth current is less than the first current. Thus, the above method achieves the purpose of slow electrode head movement, avoiding the problem of reduced cosmetic efficacy due to excessively rapid reciprocating motion of the electrode head.

[0048] For example, refer to Figure 6 As shown, assume the initial state of the electrode assembly is... Figure 6 (a) The distance between the first coil group and the second coil group is 20mm. In order for the electrode head, i.e. the movable magnet, to move at a speed of 10mm / s, i.e., from the first coil group N1 to the second coil group N2 in 2s, the first coil group N1 must first generate an attractive force. However, the attractive force F generated by the first coil group N1 is... 吸1 It must be less than the suction force F generated by the second coil group N2. 吸2 This allows the movable magnet to slowly move towards the second coil group N2. To ensure stability, a high-precision potentiometer can be incorporated into the circuitry within the movable magnet. This potentiometer monitors the magnet's position in real time, determining its speed and providing feedback to the processor. The processor then adjusts the current intensity flowing through the first coil group N1 and the second coil group N2 in real time, ensuring that F... 吸2 >F 吸1 At the same time, the speed is kept basically at the first target speed to achieve the purpose of slow movement of the electrode head. Similarly, when the movable magnet wants to return from the second coil group N2 to the first coil group N1, as... Figure 6 As shown in (b), F should be made 吸2 <F 吸1 And so on, in a continuous cycle.

[0049] In some embodiments, a certain error is allowed when determining whether the current moving speed is greater than the first target speed. For example, the current moving speed can be compared with (the first target speed ± the allowable error, such as 1 mm / s) to determine the comparison result between the two.

[0050] by Figures 2-4 Taking the beauty mask shown below as an example, please refer to the following. Figure 7 The control method for the electrode assembly is illustrated with an example, and the specific steps are as follows. The first target velocity and the second target velocity are equal and both are represented by the symbol V.

[0051] Step S3: The beauty mask begins operation. The power supply provides a positive current to coils N1 and N2, causing the coil polarities to attract the polarities of the electrode magnets. The first current I1 is less than the second current I2, resulting in F... 吸1 <F 吸2 .

[0052] Step S4: Detect whether the current moving speed of the electrode head is equal to the first target speed V ± 1 mm / s. If yes, proceed to step S7; otherwise, proceed to step S5.

[0053] Step S5: Detect whether the current moving speed is greater than V±1mm / s or less than V±1mm / s.

[0054] Step S6: If the current moving speed is greater than V, then control the second current I2 to decrease, so that F... 吸2 If the current moving speed is less than V, then the first current I1 is reduced to make F... 吸1 reduce.

[0055] Step S7: Detect whether the electrode head has moved from point 1 (coil N1) to point 2 (coil N2), that is, determine whether the moving distance of the electrode head has reached the target distance S, i.e., the distance between the two coils. If yes, proceed to step S8; if no, proceed to step S3.

[0056] Step S8: The power supply provides reverse currents to coils N1 and N2, causing the coil polarities to repel the magnet polarities of the electrode heads, and the first current I1 < the second current I2, so that F 斥1 <F 斥2 .

[0057] Step S9: Detect whether the current moving speed of the electrode head is equal to the second target speed V ± 1 mm / s. If yes, proceed to step S12; otherwise, proceed to step S10.

[0058] Step S10: Detect whether the current moving speed is greater than V±1mm / s or less than V±1mm / s.

[0059] Step S11: If the current moving speed is greater than V, then control the second current I2 to decrease, so that F... 斥2 If the current moving speed is less than V, then the first current I1 is reduced to make F... 斥1 reduce.

[0060] Step S12: Detect whether the electrode head has moved from point 2 (coil N2) to point 1 (coil N1), that is, determine whether the moving distance of the electrode head has reached the target distance S, i.e., the distance between the two coils. If yes, proceed to step S13; if no, proceed to step S8.

[0061] Step S13: Check if the working time of the beauty mask has reached the operating time t. If yes, proceed to step S14; otherwise, proceed to step S3.

[0062] Step S14: Power off the machine.

[0063] In some embodiments, the electrode assembly further includes a driving device electrically connected to the electrode assembly, which drives the electrode assembly to rotate within a defined area when in operation.

[0064] For example, such as Figures 8-10 As shown, the beauty mask 100 includes a mask body 1, an electrode assembly 30, and a driving device 3.

[0065] Specifically, the two surfaces of the mask body 1 in the thickness direction are the outer surface 13 and the inner surface 14, respectively. The electrode assembly 30 is disposed on the inner surface 14, and the side of the electrode assembly 30 away from the outer surface 13 protrudes from the inner surface 14. The driving device 3 is disposed on the mask body 1, and the driving device 3 is electrically connected to the electrode assembly 30. When the driving device 3 is working, it drives the electrode assembly 30 to rotate.

[0066] The drive device 3 on the mask body 1 provides rotational power to the electrode assembly 30, thereby driving the electrode assembly 30 to rotate and perform operations such as rotating massage on the user's face. The beauty mask 100 can also be applied to various beauty scenarios such as iontophoresis and electrical stimulation treatments (the electrode assembly 30 can emit radio frequency). For example, the electrode assembly 30 can be rotated and slid in one direction through the drive device 3. After the beauty mask 100 is worn on the face, the movement of the electrode assembly 30 can simulate the circular sliding motion of a handheld device. Thus, compared to a handheld device, it frees the user's hands and improves user comfort. At the same time, the beauty mask 100 can precisely control the movement trajectory of the electrode assembly 30 on the skin, avoiding problems such as missed treatment areas and uneven treatment intensity, which helps to improve the uniformity and effectiveness of beauty treatments.

[0067] Reference Figure 10The driving device 3 includes a driving component 33 and a transmission assembly 34. A first gear 301 is mounted on the output shaft of the driving component 33. The transmission assembly 34 includes a second gear 321 and a connecting rod 322. The first gear 311 and the second gear 321 mesh, and the second gear 321 is connected to the electrode assembly 2 via the connecting rod 322. The power from the driving component 33 is output through the output shaft and transmitted to the connecting rod 322 via the meshing of the first gear 301 and the second gear 321. Since the connecting rod 322 is connected to the electrode assembly 30, it transmits power to the electrode assembly 30, causing the electrode assembly 30 to slide or rotate along a certain path, thus enabling the sliding use of the electrode assembly 30 and completing operations such as rotating massage on the user's face.

[0068] Based on the above structure, the adjustment of the moving speed of the electrode assembly based on the working state in this application includes: adjusting the driving parameters of the driving device based on the working state to change the moving speed of the electrode assembly, wherein the driving parameters include one or more of driving current, motor speed, and driving direction. Therefore, while precisely controlling the moving trajectory of the electrode assembly on the skin, the moving speed of the electrode assembly can also be adaptively adjusted, thereby avoiding problems such as missed treatment areas and uneven treatment intensity, further improving the uniformity and effectiveness of beauty care.

[0069] A second aspect of the present invention provides a controller including at least one processor and a memory communicatively connected to the at least one processor.

[0070] The memory stores a computer program that can be executed by at least one processor, and when the at least one processor executes the computer program, it implements the control method of the electrode assembly in the above embodiment.

[0071] According to the controller of the present invention, the moving speed of the electrode head can be dynamically adjusted, which is beneficial to fully exert the cosmetic effect.

[0072] A third aspect of the present invention provides a computer storage medium having a computer program stored thereon, wherein the computer program, when executed by a processor, implements the control method for the electrode assembly described above.

[0073] A fourth aspect of the present invention provides a beauty care device, which includes an electrode assembly and a controller as described in the above embodiments. The controller is connected to the electrode assembly and is used to control the electrode assembly.

[0074] The beauty care device according to the present invention can dynamically adjust the moving speed of the electrode head, which is beneficial to fully exert the beauty effect.
