[0057] In order to make the purpose, technical solutions and advantages of this application more clearly understood, the present application is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain this application and are not intended to limit this application.

[0058] like Figure 1 As shown, the present application provides a beauty device 100 , which includes an electrode head 101 and a controller 102 electrically connected to the electrode head 101 . The electrode head 101 is provided with a liquid outlet 1011 and at least one pair of electrode sheets 1012 .

[0059] Among them, the electrode head 101 is the device component that contacts the active area of ​​the beauty device 100. The beauty device 100 can contact the active area of ​​the user, such as the user's skin, through the electrode head 101, and perform corresponding actions on the active area to achieve a beauty effect.

[0060] The electrode head 101 is provided with a liquid outlet 1011 . The liquid outlet 1011 is a liquid outlet structure on the surface of the electrode head 101 . Its main function is to allow the beauty liquid to flow out and directly act on the action area during the use of the beauty device 100 .

[0061] The electrode head 101 is also provided with at least one pair of electrode sheets 1012. Each pair of electrode sheets 1012 includes a positive electrode sheet 10121 and a negative electrode sheet 10122. For ease of description, a pair of electrode sheets including a positive electrode sheet and a negative electrode sheet is collectively referred to as electrode sheets 1012. The electrode sheets 1012 are conductive materials attached to the electrode head 101, typically made of a highly conductive material and fixed to the electrode head. By contacting the active area, the electrode sheets 1012 can act on the active area, such as the skin, to achieve a cosmetic effect.

[0062] It can be understood that during use of the beauty device 100, each pair of electrode sheets 1012 can form a working circuit with the active area through the positive electrode sheet 10121 and the negative electrode sheet 10122. When current passes through the working circuit, the electrode sheets 1012, the beauty liquid attached to the active area, and the active area can form an integral structure, similar to a resistance-capacitance model composed of a resistor and a capacitor, that is, the electrode sheets 1012 and the active area can form an equivalent resistance-capacitance model, and the impedance of the equivalent resistance-capacitance model can indirectly reflect the content of the beauty liquid between the electrode sheets 1012 and the active area.

[0063] The controller 102 is a control component used to control the operation of the beauty device 100. The controller 102 can be electrically connected to the electrode head 101. When the beauty device 100 is in use, the controller 102 can perform impedance detection on the equivalent resistance-capacitance model formed between the electrode sheet 1012 on the electrode head 101 and the active area to obtain the contact impedance between the electrode sheet 1012 and the active area.

[0064] Specifically, the controller 102 can perform impedance detection on the equivalent resistance-capacitance model formed between the electrode sheet 1012 and the active area to obtain at least two sets of contact impedances, and determine the average contact impedance between the electrode sheet 1012 and the active area based on each contact impedance. When it is determined based on the average contact impedance that the active area meets the liquid replenishment conditions, the beauty device 100 is controlled to replenish liquid to the active area through the liquid outlet 1011.

[0065] In some embodiments, the beauty device further includes a liquid storage container, which is connected to the liquid outlet via an infusion tube, a liquid outlet pump is provided on the infusion tube, and the controller is in communication with the liquid outlet pump.

[0066] Among them, the liquid storage container is a container component for storing beauty liquid. Users can inject the beauty liquid they need to use into the liquid storage container for storage. During actual use, the beauty liquid can be directly transported to the liquid outlet through the infusion tube under the action of the liquid outlet pump to replenish the liquid in the active area.

[0067] The liquid discharge pump is a power device used to transfer the beauty liquid from the liquid storage container to the liquid outlet. When the liquid discharge pump is started, it can provide power for the movement of the beauty liquid by generating a pressure difference, thereby realizing the transmission of the liquid.

[0068] Specifically, when the controller determines that the active area meets the fluid replenishment conditions, it can control the fluid outlet pump to start, and transport the beauty liquid in the liquid storage container to the fluid outlet through the infusion tube to replenish the fluid in the active area. After the fluid replenishment is completed, the controller can control the fluid outlet pump to shut down and stop the fluid replenishment process in the active area.

[0069] In some embodiments, the liquid storage container includes a liquid storage tank and a liquid storage tank cover. By providing the liquid storage tank cover, when the beauty liquid in the liquid storage tank needs to be replenished, the cover can be directly opened to add liquid, which is convenient to operate and will not cause waste of beauty liquid.

[0070] In some embodiments, the liquid storage compartment cover may be made of a waterproof and breathable membrane. Small holes in the waterproof and breathable membrane are left on the liquid storage compartment cover to keep the air pressure inside the liquid storage compartment consistent with the outside air pressure, avoiding the formation of negative pressure that prevents the beauty liquid from being pumped out. At the same time, the sealing cover can ensure that the beauty liquid does not leak out.

[0071] In some embodiments, the liquid storage container is further provided with a liquid content detection component, which is in communication with the controller and is configured to detect the amount of beauty liquid in the liquid storage container. The controller can determine whether to refill the liquid storage container based on the detected amount of beauty liquid.

[0072] In the above embodiment, by providing a liquid storage container, an infusion tube, and a liquid discharge pump in the beauty device, automatic control of the discharge of the beauty liquid can be achieved, making the liquid discharge during the liquid replenishment process more accurate, effectively reducing the possibility of beauty liquid waste, and improving the utilization rate of the beauty liquid.

[0073] In order to reduce the possibility of backflow of the beauty liquid during the delivery process, in some embodiments, a check valve is provided on the infusion tube between the liquid outlet and the liquid outlet pump.

[0074] Among them, the check valve, also known as the reverse flow valve, non-return valve, back pressure valve and one-way valve, is a valve that automatically opens and closes by relying on the force generated by the flow of the medium itself in the pipeline. It is an automatic valve.

[0075] Specifically, a check valve is provided on the infusion tube between the liquid outlet and the liquid outlet pump. When the beauty liquid flows through the check valve under the action of the pressure difference generated by the liquid outlet pump, the fluid pressure of the beauty liquid will push the valve disc to open, allowing the beauty liquid to pass through. When the beauty liquid flows in the opposite direction, that is, when it flows from the liquid outlet to the liquid storage container, the fluid pressure of the beauty liquid and the dead weight of the valve disc will cause the valve disc to close, cutting off the flow, thereby preventing the beauty liquid from flowing back.

[0076] In some embodiments, the check valve is disposed in the infusion tube near the liquid outlet.

[0077] In the above embodiment, by providing a check valve on the infusion tube between the liquid outlet and the liquid outlet pump, the beauty liquid can be effectively prevented from flowing back during the delivery process, thereby causing the beauty liquid to be contaminated and wasted, thereby improving the cleanliness of the beauty liquid.

[0078] In some embodiments, as Figure 2 As shown, a beauty instrument is provided, which includes an electrode head 101, a liquid storage tank 201, a liquid storage tank cover 202, an infusion tube 203, a liquid discharge pump 204, a check valve 205, a display operating part 206, and a controller (not shown in the figure) that is respectively connected to the electrode head 101, the liquid discharge pump 204 and the display operating part 206 for communication.

[0079] Among them, the electrode head 101 includes a liquid outlet 1011, at least one pair of electrode sheets, each pair of electrode sheets includes a positive electrode sheet 10121 and a negative electrode sheet 10122, and the electrode head 101 also includes an electrode voltage / current detection component 1013. When in use, the electrode sheet on the electrode head 101 contacts the active area, and the electrode sheet and the active area will form an equivalent resistance-capacitance model. The controller can perform impedance detection on the equivalent resistance-capacitance model, and obtain the operating information of the electrode sheet during the detection process, such as the operating voltage and the operating current, through the electrode voltage / current detection component 1013. Based on the operating voltage and the operating current, corresponding data calculation and processing are performed to obtain at least two groups of contact impedances, and the average contact impedance between the electrode sheet and the active area is determined according to each contact impedance. When it is determined based on the average contact impedance that the active area meets the fluid replenishment conditions, the controller can control the liquid discharge pump 204 to start, and deliver the beauty liquid stored in the liquid storage tank 201 to the liquid outlet 1011 through the infusion tube 203, thereby replenishing the liquid in the active area. The fluid pressure generated during the delivery of the beauty liquid will push the valve flap of the check valve 205 to open, allowing the beauty liquid to pass through. When the beauty liquid flows in the opposite direction, that is, from the liquid outlet to the liquid storage container, the fluid pressure of the beauty liquid and the deadweight of the valve flap will cause the valve flap to close, cutting off the flow, thereby preventing the beauty liquid from flowing back. After the liquid discharge pump stops working, the beauty liquid lacks flow momentum, and the valve flap in the check valve will also close under the influence of its own gravity, which can also prevent the beauty liquid remaining in the infusion tube from dripping out.

[0080] When the controller determines that liquid storage tank 201 needs to be refilled with beauty liquid, it can generate a reminder to add beauty liquid and display the reminder on display operation element 206, reminding the user to add beauty liquid to the beauty device. To add beauty liquid, the user only needs to open the liquid storage tank cover 202, which is convenient and does not waste beauty liquid.

[0081] The beauty instrument provided in this embodiment can replenish beauty essence in real time, reducing the possibility of poor beauty effects due to insufficient beauty essence. At the same time, the process of automatic judgment and automatic replenishment can avoid hand fatigue and bacterial contamination caused by manual application of beauty essence, and can also avoid waste of beauty essence, thereby improving the utilization rate of beauty essence.

[0082] Based on the same inventive concept, Figure 3 As shown, the embodiment of the present application further provides a liquid replenishing method applied to the above-mentioned beauty device. The method is described by taking the application of the method to the controller in the above-mentioned beauty device as an example. The method includes the following steps:

[0083] S302 , performing impedance detection on an equivalent resistance-capacitance model formed by the electrode sheet and the active area to obtain at least two sets of contact impedances.

[0084] The active area is the region of the object where the electrode pads are located when the electrode tip contacts the object, i.e., the area on the object corresponding to the active area of ​​the electrode tip. During use of the beauty device, each pair of electrode pads can form a conductive circuit with the active area. It is understood that the active area is not a completely fixed region on the object and will change as the electrode tip moves during use.

[0085] The equivalent resistance-capacitance model is an integral structure formed by the electrode sheet, the beauty liquid attached to the active area, and the active area during the use of the beauty device. Similar to the resistance-capacitance model composed of resistors and capacitors, the impedance of the equivalent resistance-capacitance model can indirectly reflect the content of beauty liquid between the electrode sheet and the active area.

[0086] In some embodiments, because the beauty liquid contains conductive ions, the impedance of the equivalent resistance-capacitance model is negatively correlated with the beauty liquid content. Specifically, the lower the beauty liquid content between the electrode sheet and the active area, the greater the impedance of the equivalent resistance-capacitance model. Conversely, the higher the beauty liquid content between the electrode sheet and the active area, the smaller the impedance of the equivalent resistance-capacitance model. It will be appreciated that the change in the beauty liquid content with the impedance can be a linear process, for example, where the beauty liquid content changes with the impedance based on a predetermined ratio of change in content, or a nonlinear process.

[0087] Specifically, during use of the beauty device, the controller can perform impedance detection on the equivalent resistance-capacitance model formed by the electrode sheet and the active area to obtain at least two sets of contact impedances. The controller can perform impedance detection on the equivalent resistance-capacitance model formed by the electrode sheet and the active area by obtaining relevant operating parameters of the electrode sheet during use, such as the voltage and current of the electrode sheet.

[0088] S304: Determine the average contact impedance between the electrode sheet and the active area according to each contact impedance.

[0089] Specifically, after the controller performs impedance detection on the equivalent resistance-capacitance model formed by the electrode sheet and the active area to obtain multiple groups of contact impedances, it can average the multiple groups of contact impedances to determine the average contact impedance between the electrode sheet and the active area.

[0090] In some embodiments, after obtaining multiple sets of contact impedances, the controller can effectively screen the multiple sets of contact impedances, remove contact impedances that obviously do not meet the validity conditions, such as contact impedances that are obviously too large or too small, to obtain multiple sets of effective contact impedances, and then determine the average contact impedance of the click spell and the active area based on the multiple sets of effective contact impedances, which can improve the accuracy of the average contact impedance.

[0091] S306 , when it is determined based on the average contact impedance that the active area meets the liquid replenishment condition, controlling the beauty device to replenish the liquid to the active area through the liquid outlet.

[0092] The refill condition is a preset condition used to determine whether the active area needs to be refilled with liquid. If the active area meets the refill condition, it indicates that the amount of beauty serum attached to the active area is low and cannot achieve the optimal beauty effect, so the active area needs to be refilled. It is understood that the refill condition can be pre-determined by the designer and configured in the controller. For example, the refill condition can be that the average contact impedance falls within a preset refill impedance range.

[0093] Specifically, the controller compares the average contact impedance with the preset fluid replenishment conditions. When it is determined based on the comparison results that the active area meets the fluid replenishment conditions, the controller can control the beauty device to replenish liquid to the active area through the liquid outlet.

[0094] In some embodiments, when the controller determines that the active area meets the liquid replenishment conditions based on the comparison results, the controller can directly control the beauty device to replenish liquid to the active area through the liquid outlet, and detect the contact impedance between the electrode sheet and the active area during the liquid replenishment process. When it is determined that the active area does not meet the liquid replenishment conditions, the controller controls the beauty device to stop liquid replenishment and perform the beauty operation.

[0095] In the above embodiment, the beauty device contacts the active area through the electrode head. The electrode head is provided with a liquid outlet and at least one pair of electrode sheets. When in use, the electrode sheets and the active area can form an equivalent resistance-capacitance model. By performing impedance detection on the equivalent resistance-capacitance model, at least two sets of contact impedances can be obtained to characterize the contact conditions between the electrode sheets and the active area. The average contact impedance between the electrode sheets and the active area is determined based on each contact impedance. The average contact impedance can indirectly and accurately reflect the content of the beauty liquid between the electrode sheets and the active area. When it is determined based on the average contact impedance that the active area meets the liquid replenishment conditions, the beauty device is controlled to replenish the liquid to the active area through the liquid outlet. This can make the process of the beauty device replenishing the beauty liquid to the active area more automated, without the need for manual replenishment by the user. While improving the cleanliness of the beauty liquid, it can also reduce the waste of the beauty liquid and increase the utilization rate of the beauty liquid.

[0096] Impedance detection of the equivalent resistance-capacitance model formed by the electrode sheet and the active area to obtain multiple sets of contact impedances is one of the key steps in subsequently determining whether liquid replenishment of the active area is necessary.

[0097] In some embodiments, S302, impedance detection is performed on the equivalent resistance-capacitance model formed by the electrode sheet and the active area to obtain at least two sets of contact impedances, including: at the same detection frequency, at least two impedance detections are performed on the equivalent resistance-capacitance model formed by the electrode sheet and the active area to obtain at least two sets of contact impedances between the electrode sheet and the active area.

[0098] The detection frequency is the output frequency of the voltage provided to the equivalent resistance-capacitance model when performing impedance detection on the equivalent resistance-capacitance model formed by the electrode sheet and the active area.

[0099] Specifically, the controller can control the circuit inside the electrode head to provide alternating current of the same detection frequency to the electrode sheet. At this time, the positive electrode sheet and the negative electrode sheet in the electrode sheet will form a conductive circuit with the active area. The controller can perform at least two impedance tests on the equivalent resistance-capacitance model formed by the electrode sheet and the active area at this detection frequency to obtain at least two sets of contact impedances between the electrode sheet and the active area.

[0100] In some embodiments, the controller may obtain operating parameters of the electrode sheet at different times under the same detection frequency, and perform at least two impedance tests on an equivalent resistance-capacitance model formed by the electrode sheet and the active region based on the operating parameters of the electrode sheet, thereby obtaining at least two sets of contact impedances between the electrode sheet and the active region. Specifically, the operating parameters may be the operating voltage and operating current of the electrode sheet, and the controller may calculate the at least two sets of contact impedances between the electrode sheet and the active region based on the operating voltage and operating current of the electrode sheet at different times under the same detection frequency.

[0101] In the above embodiment, by performing multiple impedance detections on the equivalent resistance-capacitance model formed by the electrode sheet and the active area at the same detection frequency, multiple groups of contact impedances can be obtained. Each group of contact impedances is independent of each other, which can effectively reduce the impedance error of the average contact impedance obtained subsequently and improve the accuracy of liquid replenishment control.

[0102] In other embodiments, Figure 4 As shown, in S302, impedance detection is performed on the equivalent resistance-capacitance model formed by the electrode sheet and the active area to obtain at least two groups of contact impedances, including:

[0103] S402 : performing impedance detection on an equivalent resistance-capacitance model formed by the electrode sheet and the active area according to at least two preset detection frequencies.

[0104] Specifically, at least two different detection frequencies are preset inside the controller. The controller can output voltage to the equivalent resistance-capacitance model formed by the electrode sheet and the active area according to the preset at least two detection frequencies, thereby performing impedance detection on the equivalent impedance model.

[0105] In some embodiments, in order to prevent different detection frequencies from being too close and resulting in low discrimination, the frequency differences between the preset multiple detection frequencies are all greater than the preset difference threshold, where the preset difference threshold is a preset threshold parameter used to determine whether the discrimination between different detection frequencies meets the discrimination standard, which can be determined by the designer according to actual needs.

[0106] S404, obtaining detection impedances corresponding to the electrode sheet and the active area at different detection frequencies.

[0107] Specifically, for each detection frequency, the controller will obtain the detection impedance obtained after impedance detection of the equivalent resistance-capacitance model formed by the electrode sheet and the active area at each detection frequency, thereby obtaining multiple sets of detection impedances between the electrode sheet and the active area at different detection frequencies.

[0108] In some embodiments, for each detection frequency, the controller may obtain operating parameters of the electrode sheet at the detection frequency, and determine the detection impedance between the electrode sheet and the active area at the corresponding detection frequency based on the operating parameters of the electrode sheet at the detection frequency. Specifically, the operating parameters may be the operating voltage and operating current of the electrode sheet, and the controller may calculate the detection impedance between the electrode sheet and the active area based on the operating voltage and operating current of the electrode sheet.

[0109] S406 , determining the detection impedances corresponding to the respective detection frequencies as at least two groups of contact impedances between the electrode sheet and the active area.

[0110] Specifically, after obtaining multiple sets of detection impedances between the electrode sheet and the active area at different detection frequencies, the controller can determine the detection impedances corresponding to each detection frequency as at least two sets of contact impedances between the electrode sheet and the active area.

[0111] Taking the first detection frequency and the second detection frequency pre-set in the controller as an example, the controller can control the circuit of the electrode head to output the first detection frequency H1 to the equivalent resistance-capacitance model formed by the electrode sheet and the active area, and collect the operating voltage U1 and operating current I1 of the electrode sheet at this time through the electrode voltage / current detection unit, and calculate the detection impedance Z1 corresponding to the first detection frequency H1 based on the operating voltage U1 and the operating current I1. Subsequently, the controller can control the circuit of the electrode head to output the second detection frequency H2 to the equivalent resistance-capacitance model formed by the electrode sheet and the active area, and collect the operating voltage U2 and operating current I2 of the electrode sheet at this time through the electrode voltage / current detection unit, and calculate the detection impedance Z2 corresponding to the second detection frequency H2 based on the operating voltage U2 and the operating current I2. The detection impedance Z1 corresponding to the first detection frequency H1 and the detection impedance Z2 corresponding to the second detection frequency H2 are determined as two sets of contact impedances between the electrode sheet and the active area.

[0112] In the above embodiment, by obtaining the different impedances exhibited by the electrode sheet and the active area at different detection frequencies, the impedance error that may be caused by a single frequency can be effectively avoided, the accuracy of the subsequent average contact impedance can be improved, and the accuracy of the liquid replenishment control of the beauty device can be improved.

[0113] In order to improve the beauty effect of beauty equipment, generally, multiple pairs of electrode sheets are provided on the electrode head of the beauty equipment. For example, multiple pairs of electrode sheets are provided on the electrode head of a multi-stage radio frequency beauty equipment. Multiple pairs of electrode sheets can accurately control the radio frequency energy, make the heat more uniform, and thus act on the active area more efficiently. Based on this, in some embodiments, the number of electrode sheets of the beauty equipment is multiple pairs, and each pair of electrode sheets corresponds to each active sub-area in the active area, such as Figure 5 As shown, the impedance detection of the equivalent resistance-capacitance model formed by the electrode sheet and the active area in S302 includes:

[0114] S502 : For each pair of electrode sheets, obtain the sub-detection impedance of the corresponding usage sub-area of ​​the electrode sheets at the current detection frequency.

[0115] Among them, the active sub-area is a component of the active area, and the active area corresponds to the use area of ​​the electrode head. When multiple pairs of electrode sheets are provided on the electrode head, correspondingly, each pair of electrode sheets will correspond to a use sub-area on the electrode head, and the combination of each use sub-area can obtain the entire use area of ​​the electrode head. Therefore, when the beauty device is in operation, each pair of electrode sheets on the electrode head will also correspond to each active sub-area in the active area, and the combination of each active sub-area is the active area of ​​the electrode head on the object of action.

[0116] Specifically, for each pair of electrode sheets, the controller may obtain the sub-detection impedance of the corresponding usage sub-area of ​​the electrode sheet and the electrode sheet at the current detection frequency.

[0117] In some embodiments, for each pair of electrode sheets, the controller can obtain the operating parameters of the electrode sheets at the current detection frequency, such as the operating voltage and operating current of the electrode sheets, and determine the sub-detection impedance of the sub-area corresponding to the electrode sheets at the current detection frequency based on the operating parameters of the electrode sheets.

[0118] S504 , calculating the average sub-detection impedance of the equivalent resistance-capacitance model formed by each pair of electrode sheets and the active area according to each sub-detection impedance.

[0119] Specifically, after obtaining the sub-detection impedances of all electrode sheets, the controller can calculate the average sub-detection impedances of all electrode sheets based on each sub-detection impedance, and determine the average sub-detection impedance as the average sub-detection impedance of the equivalent resistance-capacitance model formed by each pair of electrode sheets and the active area.

[0120] S506: Determine the average sub-detection impedance as the contact impedance between each pair of electrode sheets and the active area at the current detection frequency.

[0121] Specifically, the controller may determine the calculated average sub-detection impedance as the contact impedance between each pair of electrode sheets and the active area at the current detection frequency.

[0122] In the above embodiment, by obtaining the sub-detection impedance of each pair of electrode sheets and calculating the average sub-detection impedance of the equivalent resistance-capacitance model formed by each pair of electrode sheets and the active area based on each sub-detection impedance, the determination error of the contact impedance between each pair of electrode sheets and the active area can be reduced, and the accuracy of the contact impedance can be improved.

[0123] Determining whether the active area meets the rehydration conditions is a key step in subsequent liquid replenishment. In some embodiments, the rehydration method of the beauty device further includes: determining that the active area meets the rehydration conditions when the average contact impedance is greater than a preset impedance threshold.

[0124] The preset impedance threshold is a preset threshold parameter used to determine whether the beauty serum content in the active area needs to be replenished. The preset impedance threshold can be determined by the designer based on the minimum beauty serum content required to maintain the optimal beauty effect in the active area. That is, the designer can determine the impedance corresponding to the minimum beauty serum content required to maintain the optimal beauty effect in the active area as the preset impedance threshold.

[0125] Specifically, when the average contact impedance is greater than the preset impedance threshold, it means that the beauty liquid content in the action area cannot maintain the optimal beauty effect of the action area, and the controller can determine that the action area meets the liquid replenishment condition.

[0126] In the above embodiment, by presetting the impedance threshold, after obtaining the average contact impedance between the electrode sheet and the active area, it is possible to quickly determine whether the active area meets the rehydration conditions based on the comparison result between the average contact impedance and the preset impedance threshold, thereby improving the accuracy and efficiency of the rehydration condition judgment.

[0127] In other embodiments, when the average contact impedance is less than or equal to the preset impedance threshold, it indicates that the beauty liquid content in the active area can maintain the optimal beauty effect of the active area, and the controller can determine that the active area does not meet the rehydration conditions.

[0128] After determining that the action area meets the fluid refilling condition based on the preset impedance threshold, in some embodiments, such as Figure 6 As shown, controlling the beauty device to replenish the liquid to the active area through the liquid outlet in S306 includes:

[0129] S602: Determine an impedance difference between an average contact impedance and a preset impedance threshold.

[0130] Specifically, when the controller determines that the action area meets the fluid replenishment condition based on the average contact impedance and the preset impedance threshold, the controller can calculate the impedance difference between the average contact impedance and the preset impedance threshold.

[0131] S604: Determine the liquid replenishment amount that matches the impedance difference according to the preset correspondence between the impedance difference and the liquid replenishment amount.

[0132] The liquid replenishment amount refers to the amount of beauty serum that should be replenished when the liquid is replenished in the active area. It is understood that the controller is pre-set with a corresponding relationship between the impedance difference and the liquid replenishment amount. This relationship can be determined by the designer based on experimental data or empirical data.

[0133] Specifically, after obtaining the impedance difference between the average contact impedance and the preset impedance threshold, the controller can call the preset correspondence between the impedance difference and the liquid replenishment amount, and search for the liquid replenishment amount that matches the impedance difference between the average contact impedance and the preset impedance threshold in the correspondence.

[0134] S606: Control the beauty device to replenish liquid to the action area through the liquid outlet according to the liquid replenishment amount.

[0135] Specifically, after finding the liquid replenishment amount that matches the impedance difference between the average contact impedance and the preset impedance threshold, the controller can control the beauty device to replenish the liquid to the active area through the liquid outlet according to the liquid replenishment amount.

[0136] In some embodiments, the controller can determine the operating parameters of the liquid outlet pump according to the liquid replenishment amount, such as the operating time, operating pressure, etc., and control the operation of the liquid outlet pump based on the operating parameters of the liquid outlet pump to transport the beauty liquid from the liquid storage container to the liquid outlet to replenish the liquid in the active area.

[0137] In the above embodiment, when it is determined that the active area needs to be replenished with liquid, the matching liquid replenishment amount is determined by the impedance difference between the average contact impedance and the preset impedance threshold, and the beauty device is controlled to replenish the liquid in the active area according to the liquid replenishment amount. This can effectively improve the control accuracy of the liquid replenishment process and reduce the probability of waste due to excessive liquid replenishment or repeated replenishment due to insufficient liquid replenishment.

[0138] During the operation of beauty equipment, in addition to paying attention to whether the active area needs to be replenished with liquid, the amount of beauty liquid stored in the beauty equipment is also one of the key factors affecting the operation of the beauty equipment.

[0139] In some embodiments, the method for replenishing liquid in a beauty device further includes obtaining a level of liquid stored in a liquid storage container of the beauty device. If the level of liquid is less than a preset level threshold, generating and displaying a liquid refill reminder, the liquid refill reminder being used to remind the user to refill the liquid in the beauty device.

[0140] The preset level threshold is a parameter used to determine whether the beauty liquid in the beauty device needs to be refilled. The preset level threshold can be determined by the designer based on the actual operating requirements of the beauty device. For example, the designer can determine the minimum level of beauty liquid required to maintain normal operation of the beauty device based on experimental or empirical data, and set the minimum level of beauty liquid as the preset level threshold.

[0141] Specifically, during the operation of the beauty device, the controller can obtain the amount of beauty liquid stored in the liquid storage container of the beauty device, compare the amount of beauty liquid with a preset amount threshold, and generate and display a beauty liquid adding prompt message when the amount of beauty liquid is less than the preset amount threshold, thereby reminding the user to add beauty liquid to the beauty device through the beauty liquid adding prompt message.

[0142] In some embodiments, the controller may detect the amount of the beauty liquid stored in the liquid storage container through a beauty liquid amount detection component in the liquid storage container to obtain the amount of the beauty liquid stored in the liquid storage container.

[0143] In some embodiments, the controller may display the generated reminder information for adding beauty liquid through a display operation element to remind the user to add beauty liquid to the beauty device.

[0144] Further, such as Figure 7 As shown, when the amount of beauty serum is less than the preset amount threshold, a reminder message for adding beauty serum is generated and displayed, including:

[0145] S702: When the remaining amount of the beauty liquid is less than a preset threshold, the total amount of liquid replenished to the active area after the beauty device is activated is obtained.

[0146] Among them, the total liquid replenishment volume refers to the total amount of liquid replenished to the active area after the beauty device is started and operated this time.

[0147] Specifically, when the amount of beauty liquid in the storage container is less than the preset storage threshold, it indicates that the user needs to be reminded to add beauty liquid to the beauty device. In order to improve the accuracy of beauty liquid addition and avoid excessive addition resulting in the beauty liquid being stored in the liquid storage container for a long time and being contaminated and wasted, or insufficient addition resulting in the need for repeated addition during subsequent operation, the controller can obtain the total amount of liquid replenished to the active area after the beauty device is started.

[0148] In some embodiments, when the beauty device is started, the controller can first obtain the initial beauty liquid stock in the beauty device. If it is subsequently determined that the beauty liquid stock is less than a preset stock threshold, the difference between the initial beauty liquid stock and the beauty liquid stock is calculated to obtain the total liquid replenishment amount for replenishing the active area after the beauty device is started.

[0149] In other embodiments, each time the controller replenishes the active area with liquid, it records the amount of liquid replenished to obtain liquid replenishment record information. If it is determined that the remaining amount of beauty liquid is less than a preset level threshold, the controller can determine the total amount of liquid replenished to the active area after the beauty device was activated based on the liquid replenishment record information.

[0150] S704: Determine the liquid consumption rate of the beauty device according to the operating time of the beauty device in this operating cycle and the total liquid replenishment amount.

[0151] Among them, the operation cycle refers to the cyclic operation process of the beauty device from the start to the end of operation. The beauty device can realize a variety of beauty functions. The beauty functions triggered and selected by the user during use are different, and the corresponding operation cycles are also different. Different operation cycles correspond to different cycle operation durations.

[0152] Specifically, after obtaining the total liquid replenishment amount, the controller can first determine the operating time of the beauty device in this operating cycle, and determine the liquid consumption rate of the beauty device according to the ratio of the total liquid replenishment amount to the operating time.

[0153] S706 : Determine an estimated liquid demand of the beauty device based on the liquid consumption rate and the remaining operating time of the beauty device in this operating cycle.

[0154] Specifically, after determining the liquid consumption rate of the beauty device, the controller can determine the remaining operating time of the beauty device in this operating cycle based on the cycle operating time and the operating time of the beauty device in this operating cycle, and determine the liquid demand of the beauty device in the rainy season based on the liquid consumption rate and the remaining operating time.

[0155] In some of these embodiments, the controller may determine the estimated liquid demand of the cosmetic device as a product of the liquid consumption rate and the remaining operating time.

[0156] S708 , generating and displaying a reminder message for adding beauty liquid based on the difference between the estimated liquid demand and the remaining amount of beauty liquid.

[0157] Specifically, after determining the estimated liquid requirement of the beauty device, the controller may calculate the difference between the estimated liquid requirement and the amount of beauty liquid stored, and generate and display a beauty liquid adding prompt message based on the beauty liquid difference.

[0158] In the above embodiment, the controller determines the estimated liquid demand of the beauty device during the remaining operating time, and generates a beauty liquid addition prompt based on the difference between the estimated liquid demand and the beauty liquid inventory. This can accurately prompt the user of the amount of beauty liquid that needs to be added, improve the accuracy of beauty liquid addition, and avoid excessive addition that causes the beauty liquid to be stored in the liquid storage container for a long time and be contaminated and wasted, or excessive addition that causes repeated addition during subsequent operation.

[0159] In some embodiments, as Figure 8 As shown, a liquid replenishing method for a beauty device is provided, and the method is applied to Figure 2 The beauty instrument shown is used as an example for explanation.

[0160] First, the beauty instrument starts running. During operation, the controller will perform impedance detection on the equivalent resistance-capacitance model formed by the electrode sheet and the facial skin.

[0161] Specifically, the controller can output a first detection frequency H1 to the electrode head, and detect the electrode sheet through the electrode voltage / current detection component set in the electrode head, to obtain the operating voltage U1 and operating current I1 of the electrode sheet, and calculate the first contact impedance Z1 between the electrode head and the facial skin based on the operating voltage U1 and operating current I1. Subsequently, the controller can output a second detection frequency H2 to the electrode head, and detect the electrode sheet through the electrode voltage / current detection component set in the electrode head, to obtain the operating voltage U2 and operating current I2 of the electrode sheet, and calculate the second contact impedance Z2 between the electrode head and the facial skin based on the operating voltage U2 and operating current I2.

[0162] After obtaining the first contact impedance Z1 and the second contact impedance Z2 , an average contact impedance Z=( Z1 + Z2 ) / 2 of the first contact impedance Z1 and the second contact impedance Z2 is calculated.

[0163] The average contact impedance Z is compared with the preset impedance threshold Z0. When Z is less than or equal to Z0, it is determined that the facial skin does not meet the rehydration conditions, and the process returns to the step of performing impedance detection on the equivalent resistance-capacitance model formed by the electrode sheet and the facial skin.

[0164] When Z is greater than Z0, it is determined that the facial skin meets the fluid replenishment conditions, and the impedance difference R1 between the average contact impedance Z and the preset impedance threshold Z0 is calculated. According to the correspondence between the preset impedance difference and the liquid replenishment amount, the liquid replenishment amount C1 that matches the impedance difference R1 is determined, and the beauty instrument is controlled to replenish liquid to the facial skin through the liquid outlet according to the liquid replenishment amount C1.

[0165] During the operation of the beauty instrument, the controller can also obtain the beauty liquid stock C2 stored in the liquid storage tank of the beauty instrument, compare the beauty liquid stock C2 with the preset stock threshold C, and when the beauty liquid stock C2 is greater than the preset stock threshold C, return to execute the step of obtaining the beauty liquid stock C2 stored in the liquid storage container of the beauty instrument.

[0166] When the beauty liquid stock C2 is less than or equal to the preset stock threshold C, the total liquid replenishment amount C of the facial skin after the beauty instrument is started is obtained. 总 , according to the running time T of the beauty instrument in this running cycle 运行 and total fluid intake C 总 , determine the liquid consumption rate of the beauty instrument S=C 总 / T 运行 .

[0167] Based on the liquid consumption rate S and the remaining operating time T of the beauty instrument in this operating cycle 剩余 , determine the expected liquid demand C of the beauty instrument 预计 =S×T 剩余 .

[0168] Calculate the expected fluid requirement C 预计 The difference C between the remaining amount of beauty essence and C2 差值 , according to the difference C of beauty serum 差值 Generate reminder information for adding beauty serum, and display the reminder information through the display operation element.

[0169] The liquid replenishment method of the beauty instrument in this embodiment can replenish beauty liquid in real time, reducing the possibility of poor beauty effects due to insufficient beauty liquid. At the same time, the automatic judgment and automatic replenishment process can avoid hand fatigue and bacterial contamination caused by manual application of beauty liquid, and can also avoid waste of beauty liquid, thereby improving the utilization rate of beauty liquid.
