Description

Technical Field

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

[0002] Beauty instruments can be used to improve the condition of human skin. With the improvement of living standards, the popularity of home beauty instruments is increasing. The working principle of beauty instruments is to output specific radio wave signals to the massage head motor through a microcontroller unit, which contacts the skin surface to generate an electric current that can penetrate the epidermis, heating the collagen fibers in the dermis, which is beneficial to the generation of new collagen, thereby achieving the effect of improving wrinkles and tightening the skin. At the same time, it can promote the opening of skin capillaries, thereby promoting the penetration of skin care products such as beauty serums and essences into the skin.

[0003] Existing beauty devices output signals according to the set mode when turned on, regardless of whether they are in contact with the skin or not. The end of the mode is determined based on the time. The energy acting on the skin during use cannot be controlled and the effect cannot be guaranteed. If the operator is not skilled and stays in one position for too long, it is very easy to cause excessive output energy, resulting in safety issues such as skin damage. Summary of the invention

[0004] In view of this, the present invention provides a beauty instrument output control method, device, beauty instrument and storage medium to solve the safety problems such as excessive output energy and skin damage caused by unskilled operation and staying in one position for too long.

[0005] In a first aspect, the present invention provides a method for controlling the output of a beauty instrument, wherein the beauty instrument comprises at least an electrode sheet, and the method comprises obtaining a digital signal value of a current working output of the electrode sheet and a digital signal value of a historical output of the electrode sheet during a current working process; analyzing and comparing the digital signal value of the current working output with the digital signal value of the historical output to determine whether the electrode sheet is in a state of moving close to the face; if the electrode sheet is not in a state of moving close to the face, reducing the signal amplitude of the electrode sheet, and controlling the electrode sheet to output a signal with the reduced signal amplitude.

[0006] The beauty instrument output control method provided by the present invention obtains the digital signal value of the current working output of the electrode sheet and the digital signal value of the historical output in the current working process, and analyzes and compares the digital signal value of the current working output with the digital signal value of the historical output, so as to determine whether the electrode sheet is in a face-closed moving state. If the electrode sheet is not in the face-closed moving state, the signal amplitude of the electrode sheet is reduced, and the electrode sheet is controlled to output a signal with the reduced signal amplitude, so as to reduce the output signal amplitude first when there is no contact or no movement, avoid safety problems such as skin damage, and improve the safety and reliability of the use of the beauty instrument.

[0007] In an optional embodiment, after controlling the electrode sheet to output a signal with a reduced signal amplitude, the method further includes: timing and accumulating a first time length currently recorded, the first time length being the time length during which the electrode sheet outputs a signal with a reduced signal amplitude during the current working process; determining whether the first time length after timing accumulation exceeds a preset abnormal time length threshold; if the first time length after timing accumulation exceeds the preset abnormal time length threshold, controlling the electrode sheet to pause outputting the signal.

[0008] If the present invention determines that the duration of the electrode sheet outputting the signal with the reduced signal amplitude exceeds the abnormal duration threshold, indicating that the beauty instrument is in a state of no movement or no contact with the face for a long time, the electrode sheet is controlled to suspend the output of the signal to avoid harm, thereby improving the safety and reliability of the use of the beauty instrument.

[0009] In an optional implementation, the method further includes: if it is detected that the electrode sheet is in a face-close moving state, clearing the first duration of the current record.

[0010] The present invention ensures that the premise for controlling the electrode sheet to pause outputting signals is that the beauty instrument has reached a continuous preset abnormal time threshold and is in a non-face-to-face or non-moving state, thereby avoiding the situation in which the user moves the beauty instrument close to the face during the accumulation of the first time, but still controls the electrode sheet to pause output when the preset abnormal time threshold is reached, thereby affecting the user's normal use of the beauty instrument.

[0011] In an optional embodiment, the method also includes: if the electrode sheet is in a face-close moving state, controlling the electrode sheet to output a signal with a preset normal signal amplitude; accumulating the second time duration of the electrode sheet outputting the signal with the normal signal amplitude during the current working process, and determining whether the second time duration reaches the preset mode working time duration; if the second time duration reaches the preset mode working time duration, controlling the beauty instrument to shut down.

[0012] The present invention controls the electrode sheet to output a signal with a normal signal amplitude only after determining that the electrode sheet is in a face-adjacent moving state, thereby ensuring both the use effect of the beauty instrument and the safety of the use of the beauty instrument.

[0013] In an optional embodiment, the digital signal value of the current working output is analyzed and compared with the digital signal value of the historical output to determine whether the electrode sheet is in a face-touching moving state, including: determining whether the digital signal value of the current working output and the digital signal value of the historical output are less than a preset signal threshold, and the preset signal threshold is not greater than the digital signal value of the electrode sheet when it is not in a face-touching state; calculating the mean and standard deviation of the digital signal value of the current working output and the digital signal value of the historical output; if the digital signal value of the current working output and the digital signal value of the historical output are less than the preset signal threshold, and the standard deviation is greater than the preset standard deviation threshold, then it is determined that the electrode sheet is in a face-touching moving state.

[0014] The present invention determines whether the electrode sheet is in a face-attaching state by determining whether the digital signal value of the current working output of the electrode sheet and the digital signal value of the historical output are less than a preset signal threshold, and determines whether the electrode sheet is in a moving state by calculating the standard deviation of the digital signal value of the current working output and the digital signal value of the historical output. The current state of the electrode sheet can be accurately determined, and then the electrode sheet can be controlled to accurately output signals.

[0015] In an optional embodiment, the method further includes: in response to the beauty instrument being powered on, executing the step of obtaining the digital signal value of the current working output of the electrode sheet and the digital signal value of the historical output of the electrode sheet during the current working process based on a detection cycle, to determine whether the electrode sheet is in a state of moving close to the face.

[0016] In an optional embodiment, the method further includes: executing the step of reducing the signal amplitude of the electrode sheet if the electrode sheet is not in a face-close moving state based on the output cycle, and controlling the electrode sheet to output a signal with the reduced signal amplitude, and the detection cycle and the output cycle are obtained by pre-dividing the set beauty instrument output control cycle.

[0017] The present invention uses time division multiplexing to perform corresponding operations in the detection cycle and the output cycle respectively, thereby ensuring that the detection cycle and the output cycle are executed independently. For example, when obtaining the digital signal value of the electrode sheet, it will not be affected by the output signal of the electrode sheet, thereby improving the reliability of the beauty instrument.

[0018] In a second aspect, the present invention provides a beauty instrument output control device, the beauty instrument comprising at least an electrode sheet, the device comprising: a signal value acquisition module, for acquiring a digital signal value of a current working output of the electrode sheet and a digital signal value of a historical output of the electrode sheet during a current working process; an electrode sheet state judgment module, for analyzing and comparing the digital signal value of the current working output with the digital signal value of the historical output, to determine whether the electrode sheet is in a face-close moving state; a signal amplitude adjustment module, for reducing the signal amplitude of the electrode sheet if the electrode sheet is not in a face-close moving state, and controlling the electrode sheet to output a signal with the reduced signal amplitude.

[0019] In a third aspect, the present invention provides a beauty instrument, comprising: a detection module, a signal output module, an electrode sheet and a controller, wherein the electrode sheet is connected to the detection module and the signal output module respectively, and the controller is connected to the detection module and the signal output module, wherein the detection module is used to obtain the digital signal value of the current working output of the electrode sheet, and send the obtained digital signal value of the current working output of the electrode sheet to the controller; the signal output module is used to adjust the signal amplitude of the electrode sheet according to the control instruction of the controller, so that the electrode sheet outputs a signal based on the adjusted signal amplitude; the controller comprises: a memory and a processor, the memory and the processor are communicatively connected to each other, computer instructions are stored in the memory, and the processor executes the beauty instrument output control method of the above-mentioned first aspect or any corresponding embodiment thereof by executing the computer instructions.

[0021] In an optional implementation, the switching module is a switch control circuit.

[0022] In a fourth aspect, the present invention provides a computer-readable storage medium having computer instructions stored thereon, the computer instructions being used to enable a computer to execute the beauty instrument output control method of the first aspect or any corresponding embodiment thereof.

[0031] In order to make the purpose, technical solution and advantages of the embodiments of the present invention clearer, the technical solution in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the present invention.

[0032] Some existing beauty devices output signals according to the set mode when turned on, regardless of whether they are in contact with the skin. Whether the mode is ended is determined based on the time. The energy acting on the skin during use cannot be controlled, and the use effect cannot be guaranteed. If the operator is not skilled in operation and stays in one position for too long, it is very easy to cause excessive output energy, resulting in safety problems such as skin damage. The existing solution determines whether the skin is in contact and outputs a signal based on the pressure by adding a pressure sensor. However, adding a pressure sensor will increase the development cost of the beauty device, or the pressure sensor may have errors due to mechanical fatigue or environmental factors during operation. Therefore, the present invention does not need to add additional sensors, but uses the electrode sheets required by the beauty device itself as detectors to determine whether the skin is in contact through the digital signal value of the electrode sheets.

[0033] According to an embodiment of the present invention, an embodiment of a beauty instrument output control method is provided. It should be noted that the steps shown in the flowchart of the accompanying drawings can be executed in a computer system such as a set of computer executable instructions, and although a logical order is shown in the flowchart, in some cases, the steps shown or described can be executed in an order different from that shown here.

[0034] In this embodiment, a beauty instrument output control method is provided, which is applied to a beauty instrument, wherein the beauty instrument at least includes an electrode sheet. Figure 1 is a flow chart of a beauty instrument output control method according to an embodiment of the present invention. Figure 1 As shown, the process includes the following steps:

[0035] Step S101, obtaining the digital signal value output by the electrode sheet during the current operation and the digital signal value output by the electrode sheet in the history during the current operation.

[0036] The present invention is implemented by obtaining the digital signal value output by the electrode sheet during the current working process of the electrode sheet and storing it, wherein the digital signal value is the digital signal value after analog-to-digital conversion (Analog to Digital Converter, AD), and the skin contact state is determined by using the different impedance values ​​generated by whether the electrode sheet contacts the skin or not, and then the different AD value signals generated by voltage division, and the digital signal value can be a voltage value; and the digital signal value of the historical output of the electrode sheet during the current working process can be obtained, such as obtaining 10 groups of historical AD data, and one group of AD data can include multiple digital signal values, which is only for example and not limited.

[0037] Step S102: Analyze and compare the current digital signal value output with the historical digital signal value output to determine whether the electrode sheet is in a face-adjacent moving state.

[0038] The embodiment of the present invention can determine whether the electrode sheet is in a face-attached state by the digital signal value, and can also determine whether the beauty instrument is in a moving state by analyzing the change characteristics of the digital signal value of the current working output and the digital signal value of the historical output according to the change characteristics of the signal during the movement. Figure 2 The voltage value change characteristics of the beauty instrument when there is no essence and no contact with the face can be represented by a dotted line, the voltage value change characteristics of the beauty instrument when it is in the state of contact with the face and not moving can be represented by a solid line, and the voltage value change characteristics of the beauty instrument when it is in the state of contact with the face and moving can be represented by a fluctuating solid line, wherein the first voltage value change characteristic corresponding to the beauty instrument when it is not contacted with the face is that the first voltage value is the largest and has no fluctuation, the second voltage value change characteristic corresponding to the beauty instrument when it is in the state of contact with the face and not moving is that the second voltage value is the smallest and has no fluctuation, and the third voltage value change characteristic corresponding to the beauty instrument when it is in the state of contact with the face and moving is that the third voltage value fluctuates up and down around the second voltage value, for example only.

[0039] The embodiment of the present invention can sort, average, compare and other analytical operations on the digital signal values ​​of the current working output and the digital signal values ​​of the historical output to obtain the maximum value, minimum value and average value of all the digital signal values. It can be determined whether the calculated average value is less than the first voltage value. If it is less than the first voltage value, it can be determined that the beauty device is in a face-touching state. It can be determined whether there is a difference in amplitude between the maximum value, the minimum value and the average value. If it is determined that there is a difference in amplitude and the differences in the two amplitudes are relatively similar, it can be determined that the beauty device is in a moving state, that is, it is determined whether the AD data is less than the first voltage value and there is fluctuation, then it is determined that the beauty device is in a face-touching moving state, otherwise, it is determined that it is not in a face-touching moving state. This is just an example.

[0040] Step S103: if the electrode sheet is not in the face-touching moving state, the signal amplitude of the electrode sheet is reduced, and the electrode sheet is controlled to output a signal with the reduced signal amplitude.

[0041] In the embodiment of the present invention, if it is determined that the electrode sheet is not in a state of moving close to the face, the signal amplitude of the electrode sheet can be reduced first to reduce the output energy, and the electrode sheet can be controlled to output the signal with the reduced signal amplitude. If it is determined that the electrode sheet is in a state of moving close to the face, the electrode sheet can be controlled to output the signal according to the preset normal signal amplitude. This is just an example.

[0042] The beauty instrument output control method provided by the present invention obtains the digital signal value of the current working output of the electrode sheet and the digital signal value of the historical output in the current working process, and analyzes and compares the digital signal value of the current working output with the digital signal value of the historical output, so as to determine whether the electrode sheet is in a face-closed moving state. If the electrode sheet is not in the face-closed moving state, the signal amplitude of the electrode sheet is reduced, and the electrode sheet is controlled to output a signal with the reduced signal amplitude, so as to reduce the output signal amplitude first when there is no contact or no movement, avoid safety problems such as skin damage, and improve the safety and reliability of the use of the beauty instrument.

[0043] In this embodiment, a method for controlling output of a beauty instrument is provided. The beauty instrument at least includes an electrode sheet. Figure 3 is a flow chart of a beauty instrument output control method according to an embodiment of the present invention. Figure 3 As shown, the process includes the following steps:

[0044] Step S301, obtaining the digital signal value output by the electrode sheet during the current operation and the digital signal value output by the electrode sheet during the current operation. Figure 1 Step S101 of the illustrated embodiment will not be described in detail here.

[0045] Step S302: Analyze and compare the current working output digital signal value with the historical output digital signal value to determine whether the electrode sheet is in a face-attaching moving state.

[0046] Specifically, the above step S302 includes:

[0047] Step S3021, determining whether the current working output digital signal value and the historical output digital signal value are less than a preset signal threshold.

[0048] The preset signal threshold is no greater than the digital signal value when the electrode sheet is not in the face-attached state.

[0049] Step S3022, calculating the average value and standard deviation of the digital signal value of the current working output and the digital signal value of the historical output.

[0050] Step S3023: If the current working output digital signal value and the historical output digital signal value are less than the preset signal threshold, and the standard deviation is greater than the preset standard deviation threshold, it is determined that the electrode sheet is in the face-to-face moving state.

[0051] The embodiment of the present invention can determine whether the digital signal value of the current working output and the digital signal value of the historical output are less than a preset signal threshold, wherein the preset signal threshold can be set to be less than or equal to the digital signal value when the electrode sheet is in a non-face-attached state, indicating that the electrode sheet generates a smaller digital signal value with the skin when it is in contact with the face. Then, the average and standard deviation of the digital signal value of the current working output and the digital signal value of the historical output can be calculated. The standard deviation indicates the degree of deviation between the data and the average value to determine whether the data fluctuates, and whether the standard deviation is greater than a preset standard deviation threshold. The preset standard deviation threshold can be determined according to the actual working conditions and model of the beauty instrument, without limitation. If it is determined that the digital signal value of the current working output is less than the preset signal threshold, and the standard deviation is greater than the preset standard deviation threshold, it can be determined that the electrode sheet is in a face-attached and moving state. Otherwise, the electrode sheet is in a non-face-attached state or a face-attached and non-moving state. This is just an example.

[0052] The present invention determines whether the electrode sheet is in a face-attaching state by determining whether the digital signal value of the current working output of the electrode sheet and the digital signal value of the historical output are less than a preset signal threshold, and determines whether the electrode sheet is in a moving state by calculating the standard deviation of the digital signal value of the current working output and the digital signal value of the historical output. The current state of the electrode sheet can be accurately determined, and then the electrode sheet can be controlled to accurately output signals.

[0053] Step S303: If the electrode sheet is not in the face-touching moving state, the signal amplitude of the electrode sheet is reduced, and the electrode sheet is controlled to output a signal with the reduced signal amplitude. Figure 1 Step S103 of the illustrated embodiment will not be described in detail here.

[0054] Step S304, time the first duration of the current record and accumulate it; determine whether the first duration after the accumulated timing exceeds the preset abnormal duration threshold; if the first duration after the accumulated timing exceeds the preset abnormal duration threshold, control the electrode sheet to pause outputting the signal.

[0055] The first duration is the duration during which the electrode sheet outputs a signal with a reduced signal amplitude during the current working process.

[0056] The embodiment of the present invention can continue to accumulate the timing of the currently recorded first accumulated time length after determining that the electrode sheet is not in a state of moving against the face and controlling the electrode sheet to output a signal with a reduced signal amplitude, and determine in real time whether the first time length after the accumulation exceeds the preset abnormal time length threshold. The time length can be accumulated by a timer, and the setting of the abnormal time length threshold is not limited. It can be set according to actual user needs and the product model of the beauty instrument. Taking 3 seconds as an example, if the first time length after the accumulation exceeds the preset abnormal time length threshold, it means that the beauty instrument is in a state of no movement or no contact with the face for a long time, and the electrode sheet can be controlled to pause outputting signals.

[0057] If the present invention determines that the duration of the electrode sheet outputting the signal with the reduced signal amplitude exceeds the abnormal duration threshold, indicating that the beauty instrument is in a state of no movement or no contact with the face for a long time, the electrode sheet is controlled to suspend the output of the signal to avoid harm, thereby improving the safety and reliability of the use of the beauty instrument.

[0058] In an optional embodiment, if the electrode sheet is in a face-close moving state, the electrode sheet is controlled to output a signal with a preset normal signal amplitude; the second time duration of the electrode sheet outputting the signal with the normal signal amplitude during the current working process is accumulated, and it is determined whether the second time duration reaches the preset mode working time duration; if the second time duration reaches the preset mode working time duration, the beauty instrument is controlled to shut down.

[0059] If the embodiment of the present invention determines that the electrode sheet is in a face-closed moving state, the electrode sheet can be controlled to output a signal with a preset normal signal amplitude, and the second time duration of the electrode sheet outputting the signal with the normal signal amplitude in the current working process is accumulated, and it is determined whether the second time duration reaches the working time duration of the preset mode, wherein the working time duration of the preset mode is the working time duration corresponding to the beauty mode selected by the user when the beauty instrument is turned on. If the second time duration reaches the working time duration of the preset mode, the beauty instrument is controlled to shut down; if the second time duration does not reach the working time duration of the preset mode, the steps of the above embodiment are repeated until the second time duration reaches the working time duration of the preset mode.

[0060] The present invention controls the electrode sheet to output a signal with a normal signal amplitude only after determining that the electrode sheet is in a face-adjacent moving state, thereby ensuring both the use effect of the beauty instrument and the safety of the use of the beauty instrument.

[0061] In some optional implementations, if it is detected that the electrode sheet is in a state of moving close to the face, the first duration of the current record is cleared.

[0062] In the embodiment of the present invention, if the electrode sheet is judged to be in a state of moving close to the face after analyzing and comparing the digital signal value of the current working output with the digital signal value of the historical output, the electrode sheet will be controlled to output a signal with a preset normal signal amplitude, and the currently recorded accumulated first time length will be cleared to zero, to ensure that the premise for controlling the electrode sheet to pause outputting the signal is that the beauty instrument has reached a continuous preset abnormal time length threshold and is in a state of not being close to the face or not moving, to avoid the situation where the user moves the beauty instrument close to the face during the accumulation of the first time length, but the electrode sheet is still controlled to pause output when the preset abnormal time length threshold is reached, thereby affecting the user's normal use of the beauty instrument.

[0063] In some optional embodiments, in response to the beauty instrument being turned on, the step of obtaining the digital signal value of the current working output of the electrode sheet and the digital signal value of the historical output of the electrode sheet during the current working process is performed based on the detection cycle to determine whether the electrode sheet is in a state of moving close to the face.

[0064] Based on the output cycle, if the electrode sheet is not in the face-adjacent moving state, the signal amplitude of the electrode sheet is reduced, and the electrode sheet is controlled to output a signal with the reduced signal amplitude.

[0065] The detection cycle and the output cycle are obtained by dividing the preset beauty instrument output control cycle in advance.

[0066] In an embodiment of the present invention, the output control period of the beauty instrument can be set as a periodic cycle, and the digital signal value detection and signal output of the electrode piece are performed according to one periodic cycle. The specific setting can be set according to actual needs and the type of beauty instrument. Taking 100ms as the output control period of the beauty instrument as an example, the output control period of the beauty instrument can be divided into a detection period and an output period. Taking a detection period of 5ms and an output period of 95ms as an example, within the detection period, the digital signal value of the current working output of the electrode piece and the digital signal value of the historical output of the electrode piece in the current working process are obtained, wherein the digital signal value of the current working output of the electrode piece detected within 5ms is multiple digital signal values, that is, a group of digital signal values ​​has multiple digital signal values, and the digital signal value of the current working output and the digital signal value of the historical output are analyzed and compared to determine whether the electrode piece is in a face-to-face moving state.

[0067] After the detection cycle of 5ms ends, it switches to the output cycle, and performs corresponding operations based on the state of the electrode sheet during the output cycle, that is, if it is determined that the electrode sheet is in a state of moving close to the face, the electrode sheet is controlled to output a signal according to the preset normal signal amplitude, and the accumulated second time length currently recorded is timed and accumulated, and it is determined whether the second time length after the time accumulation reaches the working time length of the preset mode. If the working time length of the preset mode is reached, the beauty instrument is controlled to shut down; if it is determined that the electrode sheet is not in a state of moving close to the face, and the time accumulation of the first time length currently recorded is started, it is determined whether the first time length reaches the preset abnormal time length threshold. If not, the electrode sheet is controlled to output a signal with a reduced signal amplitude. If the first time length reaches the preset abnormal time length threshold, the electrode sheet is controlled to suspend the output signal. In the process of performing corresponding operations based on the state of the electrode sheet, after monitoring that the output cycle of 95ms ends, it continues to switch to the detection cycle and repeats the above embodiment, which is only used as an example.

[0068] The present invention uses time division multiplexing to perform corresponding operations in the detection cycle and the output cycle respectively, thereby ensuring that the detection cycle and the output cycle are executed independently. For example, when obtaining the digital signal value of the electrode sheet, it will not be affected by the output signal of the electrode sheet, thereby improving the reliability of the beauty instrument.

[0069] In this embodiment, a beauty instrument is also provided. Figure 4 As shown, the beauty instrument at least includes a detection module, a signal output module, an electrode sheet and a controller. The electrode sheet is connected to the detection module and the signal output module respectively, and the controller is connected to the detection module and the signal output module. The detection module is used to obtain the digital signal value of the current working output of the electrode sheet, and send the obtained digital signal value of the current working output of the electrode sheet to the controller; the signal output module is used to adjust the signal amplitude of the electrode sheet according to the control instruction of the controller, so that the electrode sheet outputs a signal based on the adjusted signal amplitude; the controller includes a memory and a processor, the memory and the processor are communicatively connected to each other, computer instructions are stored in the memory, and the processor executes the beauty instrument output control method of the above embodiment by executing the computer instructions. Please refer to the above embodiment for detailed description, which will not be repeated here.

[0070] In some optional embodiments, such as Figure 4 As shown, the beauty instrument also includes a switching module, through which the electrode sheet is respectively connected to the detection module and the signal output module, and the controller is connected to the switching module, wherein the controller controls the switching module to cut off the electrode sheet and the signal output module, and connect the electrode sheet and the detection module, or connect the electrode sheet and the signal output module, and cut off the electrode sheet and the detection module.

[0071] In a specific embodiment, the switching module is a switch control circuit such as a solid-state relay or a MOS tube, and the detection module is an AD detection circuit, which uses the different impedance values ​​generated by the electrode sheet contacting the skin and the different AD value signals generated by the voltage division to determine the skin contact state. At the same time, according to the change characteristics of the signal during the movement, the signal is analyzed to determine whether the beauty instrument is in a moving state.

[0072] In the embodiment of the present invention, after the beauty instrument is turned on, within the detection cycle, the controller controls the switching module to cut off the electrode sheet and the signal output module, and connect the electrode sheet and the detection module, so that the detection module detects the digital signal value of the current working output of the electrode sheet, and then determines whether the electrode sheet is currently in a face-touching moving state; when the detection cycle ends and switches to the output cycle, the controller controls the switching module to switch the electrode sheet and the detection module, and connect the electrode sheet and the signal output module. Based on whether the current electrode sheet is in a face-touching moving state, the controller sends a signal amplitude output control instruction to the signal output module. The signal output module adjusts the signal amplitude of the electrode sheet based on the signal amplitude output control instruction sent by the controller, so that the electrode sheet outputs a signal based on the adjusted signal amplitude. Please refer to the above embodiment for detailed description, which will not be repeated here.

[0073] The present invention takes into account that detection and output cannot be connected to the electrode sheet at the same time, and time-sharing multiplexing is required. The output module will not be connected during the detection period. The electrode sheet is connected and disconnected with the signal output module and the detection module respectively by using time-sharing multiplexing and a switching unit, so as to realize detection through the output signal of the electrode sheet and control the output signal of the electrode sheet.

[0074] In a specific embodiment, Figure 5 As shown, after the beauty instrument is turned on, within the detection cycle, the control switching module cuts off the electrode sheet and the signal output module, connects the electrode sheet and the detection module, detects the digital signal value of the current working output of the electrode sheet, that is, the AD signal value, and stores it, sorts, averages, compares and other analysis operations on the historical N groups of digital signal values ​​and the digital signal value of the current working output, and determines whether the digital signal value is less than the preset signal threshold and whether there is fluctuation. If it is less than the preset signal threshold and there is fluctuation, it determines whether the electrode sheet is in a face-touching moving state. After the detection cycle ends, it switches to the output cycle, controls the switching module to switch the electrode sheet and the detection module, and connects the electrode sheet and the signal output module.
