Description

Technical Field

[0001] This application relates to the field of beauty device technology, and in particular to a current control method for a beauty device, a beauty device, and a computer-readable storage medium. Background Technology

[0002] Soluble microneedles, also known as water-soluble microneedles, are typically made of soluble polymeric biomaterials. During preparation, these biomaterials are directly mixed with cosmetic drugs, allowing the medication to be preserved within the microneedle. Hydrogels are common soft ionic conductors. Due to their excellent conductivity, transparency, swelling properties, and stretchability, hydrogels dissolve rapidly through iontophoresis, allowing for controlled microneedle release. Therefore, hydrogel microneedles have begun to be used in the beauty industry, often combined with the penetration-enhancing functions of beauty devices to rapidly dissolve and penetrate the microneedle cosmetic medication. However, the conductivity of hydrogels changes significantly during dissolution, causing abrupt changes in the iontophoresis current, which can lead to a stinging sensation on the skin and, in severe cases, even skin damage. Summary of the Invention

[0003] In view of this, the main purpose of this application is to propose a current control method for a beauty device, a beauty device, and a computer-readable storage medium, aiming to solve the problem that the conductivity of the hydrogel in existing beauty devices changes significantly during the dissolution process, causing a sudden change in the ion electroosmotic current and resulting in a stinging sensation on the skin.

[0004] To achieve the above objectives, a first aspect of this application provides a current control method for a beauty device. The current control method is applied to a beauty device including an output circuit, a current detection circuit, and a hydrogel. The hydrogel is electrically connected to both the output circuit and the current detection circuit. The output circuit outputs current to the hydrogel, and the current detection circuit detects the current flowing through the hydrogel and outputs a corresponding current detection signal. The current control method includes: controlling the output circuit to output current to the hydrogel; acquiring the current detection signal; comparing the current measured current corresponding to the current detection signal at the current moment with a reference current to obtain the current change value at the current moment; determining whether the current change value at the current moment is within a preset threshold range; if it is determined that the current change value at the current moment is within the preset threshold range, then controlling the output circuit to continue outputting with the current output current; and if it is determined that the current change value at the current moment is not within the preset threshold range, then controlling the output circuit to adjust the magnitude of the current output to the hydrogel according to the current change value at the current moment, so as to reduce the amplitude of the current change flowing through the hydrogel.

[0005] The current control method for the beauty device provided in this application compares the current measured current corresponding to the current detection signal at the current moment with a reference current to obtain the current change value at the current moment. It determines whether the current flowing through the hydrogel has a sudden change by judging whether the current change value at the current moment is within a preset threshold value range. When it is determined that the current flowing through the hydrogel has a sudden change, the output circuit is controlled to adjust the magnitude of the current output to the hydrogel according to the current change value at the current moment. This allows for timely negative feedback adjustment of the current output by the output circuit, compensating for the change in ion electroosmotic current caused by the sudden change in the conductivity of the hydrogel. In this way, the amplitude of the current change flowing through the hydrogel can be reduced, thereby improving the user experience.

[0006] A second aspect of this application also provides a beauty device, comprising a hydrogel, an output circuit, a current detection circuit, and a processor. The output circuit is electrically connected to the hydrogel and is used to output current to the hydrogel. The current detection circuit is also electrically connected to the hydrogel and is used to detect the current flowing through the hydrogel and output a corresponding current detection signal. The processor is electrically connected to both the output circuit and the current detection circuit, and is used to execute the steps of the current control method of the beauty device described in the first aspect.

[0007] A third aspect of this application also provides a computer-readable storage medium storing a program that, when executed by a processor, performs the steps of the current control method for the beauty device described in the first aspect.

[0008] Additional aspects and advantages of this application will be set forth in part in the description which follows, and in part will be obvious from the description, or may be learned by practice of this application. Attached Figure Description

[0029] The following detailed description, in conjunction with the accompanying drawings, will further illustrate this application. Detailed Implementation

[0030] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this application.

[0031] Furthermore, the terms "first," "second," etc., used in this specification are used to distinguish similar objects and are not necessarily used to describe a specific order or sequence. It should be understood that such data can be interchanged where appropriate so that the embodiments of the invention described herein can be implemented in orders other than those illustrated or described herein. Additionally, the terms "comprising" and "having," and any variations thereof, are intended to cover non-exclusive inclusion; for example, a process, method, system, product, or apparatus that comprises a series of steps or units is not necessarily limited to those steps or units explicitly listed, but may include other steps or units not explicitly listed or inherent to such processes, methods, products, or apparatus.

[0032] It should be noted that, where there is no conflict, the features in the embodiments of this application can be combined with each other.

[0033] Please see Figures 1-2 This application provides a current control method for a beauty device, wherein the current control method is applied to a beauty device 100.

[0034] like Figure 1 As shown, the beauty device 100 includes an output circuit 10, a current detection circuit 20, and a hydrogel 30. The hydrogel 30 is electrically connected to the output circuit 10 and the current detection circuit 20, respectively. The output circuit 10 is used to output current to the hydrogel 30, and the current detection circuit 20 is used to detect the current flowing through the hydrogel 30 and output a corresponding current detection signal.

[0035] For example, the hydrogel 30 may include, but is not limited to, polyvinyl alcohol, chitosan, vitamins, poly-N-isopropylamide, gelatin, polyglutamic acid, and polypeptide hydrogels.

[0036] Furthermore, the beauty device 100 also includes microneedles 60 connected to the hydrogel 30. The microneedles 60 can be made of solid materials such as metal or silicon, or soluble materials that dissolve when applied to the skin using self-degradable or biodegradable materials. The microneedles 60 may contain wrinkle-improving and whitening ingredients such as botulinum toxin, retinol, and hyaluronic acid. When the microneedles 60 are applied to the target area 200 of the skin, the output circuit 10 applies an electric current to the hydrogel 30, causing the hydrogel 30 to dissolve under the influence of the current, thereby promoting the penetration of the functional materials in the microneedles 60 into the deeper layers of the skin.

[0037] Please see Figure 2 The current control method specifically includes the following steps:

[0038] Step 61: Control the output circuit 10 to output current to the hydrogel 30.

[0039] Step 62: Obtain the current detection signal.

[0040] Step 63: Compare the current measured current corresponding to the current detection signal at the current moment with a reference current to obtain the current change value at the current moment.

[0041] Step 64: Determine whether the current change value at the current moment is within a preset threshold range. If the current change value at the current moment is determined to be within the preset threshold range, proceed to step 65. If the current change value at the current moment is determined not to be within the preset threshold range, proceed to step 66.

[0042] Step 65: Control the output circuit 10 to continue outputting at the current output current.

[0043] Step 66: Based on the current change value at the current moment, control the output circuit 10 to adjust the magnitude of the current output to the hydrogel 30, so as to reduce the change amplitude of the current flowing through the hydrogel 30.

[0044] It should be noted that the conductivity of hydrogels changes significantly during dissolution, leading to abrupt changes in the iontophoresis current. Existing beauty devices output a target current to the hydrogel in a fixed pattern. When the conductivity of the hydrogel changes significantly during dissolution, the iontophoresis current will continuously fluctuate abruptly. If the device continues to output in the fixed pattern, the fluctuation range of the current flowing through the hydrogel will become increasingly larger and deviate further from the target current, potentially causing a stinging sensation on the skin, and in severe cases, even damaging the skin.

[0045] The current control method of the beauty device provided in this application obtains the current change value at the current moment by comparing the current measured current corresponding to the current detection signal at the current moment with a reference current, and then determines whether the current change value at the current moment is within the range of a preset threshold value, so as to determine in time whether the current flowing through the hydrogel 30 has changed abruptly.

[0046] Furthermore, when the current change value at the current moment is within the preset threshold range, it can be determined that the current flowing through the hydrogel 30 has not changed abruptly, indicating that the conductivity of the hydrogel has not changed significantly at the current moment. Therefore, the output circuit 10 can be controlled to maintain the current output current. When the current change value at the current moment is not within the preset threshold range, it can be determined that the current flowing through the hydrogel 30 has changed abruptly, indicating that the conductivity of the hydrogel is changing at the current moment. In this case, based on the current change value at the current moment, the output circuit 10 is controlled to adjust the magnitude of the current output to the hydrogel 30, thereby timely providing negative feedback adjustment to the current output by the output circuit 10. This compensates for the change in ion electroosmotic current caused by the abrupt change in the conductivity of the hydrogel, thereby reducing the amplitude of the current change flowing through the hydrogel 30 and improving the user experience.

[0047] The current control method for the beauty device provided in this application compares the current measured current corresponding to the current detection signal at the current moment with a reference current to obtain the current change value at the current moment. It determines whether the current flowing through the hydrogel 30 has a sudden change by judging whether the current change value at the current moment is within a preset threshold value range. When it is determined that the current flowing through the hydrogel 30 has a sudden change, the output circuit 10 is controlled to adjust the magnitude of the current output to the hydrogel 30 according to the current change value at the current moment. This allows for timely negative feedback adjustment of the current output by the output circuit 10, compensating for the change in ion electroosmotic current caused by the sudden change in the conductivity of the hydrogel, thereby reducing the amplitude of the current change flowing through the hydrogel 30 and improving the user experience.

[0048] Optionally, the beauty device 100 may further include a working level setting circuit (not shown), which receives a level setting command input by the user. In this case, step 61 may specifically include: responding to the level setting command, controlling the output circuit 10 to output a current corresponding to the level setting command to the hydrogel 30, wherein different level setting commands correspond to different currents, with higher levels corresponding to larger currents. For example, the working levels of the beauty device 100 may include levels 1 to 5.

[0049] In this embodiment of the application, step 62 specifically includes: acquiring the current detection signal at a preset time interval. For example, the preset time interval is 1ms.

[0050] Further, in one embodiment, the reference current iref is a preset current. In this case, step 63 specifically includes: subtracting the preset current from the current measured current value corresponding to the current detection signal at the current moment to obtain the current change value at the current moment. For example, when the beauty device 100 has multiple operating levels, the preset current is the current corresponding to the current operating level of the beauty device 100. Thus, the reference current iref is different for different operating levels, and the current control method provided in this application can be applied to various operating levels.

[0051] In another implementation, the reference current iref is the average current of multiple measured currents corresponding to multiple moments within a statistical period, wherein the statistical period is a time interval from the start moment to the current moment with a preset duration (e.g., 100ms). Please refer to [link to relevant documentation]. Figure 3 At this point, step 63 specifically includes the following steps:

[0052] Step 631: Calculate the average current of multiple measured currents corresponding to multiple moments within the statistical period of the current detection signal.

[0053] Step 632: Subtract the average current from the current measured current value corresponding to the current detection signal at the current moment to obtain the current change value at the current moment.

[0054] Further, the current change value at the current moment is the value obtained by subtracting the reference current iref from the current measured current corresponding to the current detection signal at the current moment. The preset threshold range includes an upper threshold and a lower threshold, wherein the upper threshold is greater than zero and the lower threshold is less than zero. For example, the absolute values ​​of the upper threshold and the lower threshold are equal; for example, the upper threshold is 0.5mA and the lower threshold is -0.5mA.

[0055] Please see Figure 4 Step 66 specifically includes the following steps:

[0056] Step 661: Determine whether the current change value at the current moment is greater than the upper threshold or less than the lower threshold.

[0057] If it is determined that the current change value at the current moment is greater than the upper threshold value, then proceed to step 662. If it is determined that the current change value at the current moment is less than the lower threshold value, then proceed to step 663.

[0058] Step 662: Control the output circuit 10 to switch from outputting the current output current to outputting the first target current.

[0059] Wherein, the first target current is less than the reference current iref.

[0060] Step 663: Control the output circuit 10 to switch from outputting the current output current to outputting the second target current.

[0061] Wherein, the second target current is greater than the reference current iref.

[0062] When the current change value at the current moment is greater than the upper threshold value, it indicates that the current flowing through the hydrogel is suddenly increasing. Therefore, controlling the output circuit 10 to output a smaller first target current value can prevent the skin from experiencing a stinging sensation. When the current change value at the current moment is less than the lower threshold value, it indicates that the current flowing through the hydrogel is suddenly decreasing. Therefore, controlling the output circuit 10 to output a larger second target current value can allow the beauty device 1 to maintain a good penetration-promoting effect.

[0063] Optionally, please refer to Figure 5 In one embodiment, step 661 may include steps 6611 to 6613, as follows:

[0064] Step 6611: Determine whether the absolute value of the current change at the current moment is greater than the preset current change threshold.

[0065] If the absolute value of the current change at the current moment is determined to be greater than the preset current change threshold, then step 6612 is executed. If the absolute value of the current change at the current moment is determined to be less than or equal to the preset current change threshold, then step 6613 is executed. The preset current change threshold is greater than the upper threshold value. For example, the preset current change threshold is 10mA.

[0066] Step 6612: Control the output circuit 10 to stop outputting current.

[0067] Step 6613: Determine whether the current change value at the current moment is greater than the upper threshold or less than the lower threshold.

[0068] After completing step 6613, proceed with step 662 or step 663.

[0069] In this embodiment, if the absolute value of the current change at the current moment is greater than the preset current change threshold, the current is considered to be uncontrollable. At this time, the output circuit 10 is controlled to stop outputting current, which can avoid large current burning the skin and improve safety.

[0070] Furthermore, the magnitude of the first target current is negatively correlated with the magnitude of the current change at the current moment. The magnitude of the second target current is positively correlated with the magnitude of the absolute value of the current change at the current moment. That is, when the current change at the current moment is greater than the upper threshold, if the current change at the current moment is larger, the output circuit 10 will output a smaller first target current; when the current change at the current moment is less than the lower threshold, if the absolute value of the current change at the current moment is larger, the output circuit 10 will output a larger second target current. In this way, the adjustment of the output current by the output circuit 10 can be matched with the change in ion electroosmotic current caused by the abrupt change in the conductivity of the hydrogel, thereby minimizing the amplitude of the current change flowing through the hydrogel 30 and further improving the user experience.

[0071] Furthermore, please refer to the following: Figure 6 and Figure 8 Step 662 specifically includes the following steps:

[0072] Step 6621: Obtain the first compensation current calibration table.

[0073] The first compensation current calibration table records a one-to-one mapping relationship between multiple current rise value intervals and multiple first compensation currents, and each of the first compensation currents is less than zero.

[0074] Step 6622: According to the first compensation current calibration table, determine the first target compensation current corresponding to the current change value at the current moment from the plurality of first compensation currents, and add the first target compensation current to the reference current to obtain the first target current.

[0075] Step 6623: Control the output circuit 10 to switch from outputting the current output current to outputting the first target current.

[0076] The first compensation current calibration table can be obtained through experimentation.

[0077] For example, in such Figure 8In the first compensation current calibration table shown, the plurality of current rise value intervals include Δi10~Δi11, Δi11~Δi12……Δi1n-1~Δi1n, where 0<Δi10<Δi11<Δi12<……<Δi1n-1<Δi1n, and Δi10 is the upper threshold value. The plurality of first compensation currents include i11, i12……i1n-1, where 0>i11>i12>……>i1n-1. For example, when the current change value at the current moment is within the current rise value interval Δi10~Δi11, then the first target compensation current is i11.

[0078] Optionally, in other embodiments, when the beauty device 100 has multiple working levels, the output circuit 10 can be controlled to switch from outputting the current output current to outputting the first target current by adjusting the working level. For example, if the higher the level, the larger the corresponding reference current, the output circuit 10 can be controlled to switch from outputting the current output current to outputting the first target current by lowering the level.

[0079] Furthermore, please refer to the following: Figures 7-8 Step 663 specifically includes the following steps:

[0080] Step 6631: Obtain the second compensation current calibration table.

[0081] The second compensation current calibration table records a one-to-one mapping relationship between multiple current drop ranges and multiple second compensation currents, and each of the second compensation currents is greater than zero.

[0082] Step 6632: According to the second compensation current calibration table, determine the second target compensation current corresponding to the current change value at the current moment from the plurality of second compensation currents, and add the second target compensation current to the reference current to obtain the second target current.

[0083] Step 6633: Control the output circuit 10 to switch from outputting the current output current to outputting the second target current.

[0084] The second compensation current calibration table can also be obtained through experimentation.

[0085] For example, in such Figure 8In the second compensation current calibration table shown, the plurality of current decrease value intervals include Δi20~Δi21, Δi21~Δi22...Δi2n-1~Δi2n, wherein 0>Δi20>Δi21>Δi22>...>Δi2n-1>Δi2n, and Δi20 is said lower threshold. Said second compensation currents include i21, i22...i2n-1, wherein 0<i21<i22<...<i2n-1. For example, when the current change value at the current moment falls within the current decrease value interval Δi21~Δi22, said second target compensation current is i22.

[0086] Optionally, in other embodiments, when said beauty instrument 100 has a plurality of operating gears, the control of switching said output circuit 10 from outputting the current output current to outputting said second target current can also be achieved by adjusting the operating gear. For example, if a higher gear corresponds to a larger reference current, the control of switching said output circuit 10 from outputting the current output current to outputting said second target current can be achieved by increasing the gear.

[0087] Optionally, said beauty instrument 100 further comprises a temperature detection circuit 50, said temperature detection circuit 50 is configured to detect the temperature of the target site and output a corresponding temperature detection signal.

[0088] Further, please refer to Figure 9 , the present application also provides another current control method, Figure 9 the current control method shown is similar to the current control method shown in Figure 2 , with the difference that: after executing said step 61 and before executing said step 62, Figure 9 the current control method shown further comprises steps 601 to 603.

[0089] Figure 9 the current control method shown specifically comprises the following steps:

[0090] Step 61, controlling said output circuit 10 to output current to said hydrogel 30.

[0091] Step 601, acquiring said temperature detection signal.

[0092] Step 602, comparing the current measured temperature corresponding to said temperature detection signal at the current moment with a reference temperature to obtain a temperature change value at the current moment.

[0093] Step 603, determining whether the absolute value of the temperature change value at the current moment is greater than a preset temperature change threshold.

[0094] If the absolute value of the temperature change at the current moment is greater than the preset temperature change threshold, then proceed to step 604. If the absolute value of the temperature change at the current moment is less than or equal to the preset temperature change threshold, then proceed to step 62.

[0095] Step 604: Control the output circuit 10 to stop outputting current.

[0096] Step 62: Obtain the current detection signal.

[0097] Step 63: Compare the current measured current corresponding to the current detection signal at the current moment with a reference current to obtain the current change value at the current moment.

[0098] Step 64: Determine whether the current change value at the current moment is within a preset threshold range. If the current change value at the current moment is determined to be within the preset threshold range, proceed to step 65. If the current change value at the current moment is determined not to be within the preset threshold range, proceed to step 66.

[0099] Step 65: Control the output circuit 10 to continue outputting at the current output current.

[0100] Step 66: Based on the current change value at the current moment, control the output circuit 10 to adjust the magnitude of the current output to the hydrogel 30, so as to reduce the change amplitude of the current flowing through the hydrogel 30.

[0101] For example, the reference temperature is the normal temperature value of the human body, such as 36.5°C.

[0102] In this embodiment, when the absolute value of the temperature change at the current moment is greater than the preset temperature change threshold, the output circuit 10 is controlled to stop outputting current, which can further improve safety by preventing high temperature burns to the skin.
