Description

Technical Field

[0001] This invention relates to the field of sensor technology, and in particular to a voltage regulation method, system, and readable storage medium for an electric toothbrush. Background Technology

[0002] Electric toothbrushes have become the preferred tool for daily oral hygiene for the general public. They clean teeth by vibrating and rotating the brush head, and can achieve better cleaning results compared with traditional toothbrushes.

[0003] In actual use, the pressure on the electric toothbrush changes due to the varying contact force between the brush head and the teeth. This alters the vibration frequency of the brush head. For example, when the contact force between the brush head and the teeth is too great, the pressure on the electric toothbrush increases. The toothbrush cannot adjust the output power of the vibration motor accordingly, ultimately affecting the cleaning effect and user experience. Summary of the Invention

[0004] This application provides a voltage stabilization method, system, and readable storage medium for an electric toothbrush. The method involves detecting first pressure data via a motor pressure sensor and second pressure data via a button pressure sensor. A first decision corresponding to the first pressure data is determined based on a preset motor pressure decision table, and a second decision corresponding to the second pressure data is determined based on a preset button pressure table. The electric toothbrush controls a vibration motor and a display module based on the first and second decisions, changing the output power of the vibration motor to maintain a stable vibration frequency of the toothbrush head, preventing changes in vibration frequency due to variations in the pressure applied to the toothbrush. This improves the cleaning effect and user experience of the electric toothbrush.

[0005] In a first aspect, this application provides a voltage stabilization method for an electric toothbrush, the method comprising: the electric toothbrush detecting first pressure data via a motor pressure sensor; the electric toothbrush detecting second pressure data via a button pressure sensor; the electric toothbrush determining a first column of the first pressure data in a preset motor pressure decision table and a second column of the second pressure data in a preset button pressure table; the electric toothbrush determining a first decision for the first column in the preset motor pressure decision table and a second decision for the second column in the preset button pressure table; the electric toothbrush controlling a vibration motor and a display module according to the first and second decisions, such that the difference between the vibration frequency of the current electric toothbrush head and a preset vibration frequency is less than a preset vibration frequency threshold.

[0006] By adopting the above technical solution, the electric toothbrush controls the vibration motor and display module by detecting the first and second pressure data. By changing the output power of the vibration motor, the vibration frequency of the electric toothbrush head can be kept stable and will not change due to changes in the pressure on the electric toothbrush. If the pressure on the electric toothbrush increases while the output power of the vibration motor remains unchanged, the vibration frequency will be too strong and will damage the teeth. By automatically adjusting the output power of the vibration motor according to the detected pressure, the cleaning effect of the electric toothbrush can be improved, damage to the gums and teeth can be reduced, and the user experience can be improved.

[0007] In conjunction with some embodiments of the first aspect, in some embodiments, before the step of the electric toothbrush detecting the first pressure data via the motor pressure sensor, the step further includes: the electric toothbrush detecting standard pressure data via the motor pressure sensor and detecting standard pressure data via the button pressure sensor; the electric toothbrush determining whether the output power of the vibration motor is a preset output power threshold; if it is not a preset power threshold, the electric toothbrush displaying a first prompt message via the display module, the first prompt message being used to prompt the user that the electric toothbrush is faulty.

[0008] By adopting the above technical solution, before the electric toothbrush detects the first pressure data, standard pressure is applied to the motor pressure sensor and the button pressure sensor of the electric toothbrush. The electric toothbrush determines whether the vibration motor is at the preset output power threshold when both sensors are under standard force. If it is not at the preset power threshold, the user is prompted that the electric toothbrush is faulty. This ensures that the electric toothbrush is functioning properly to change the output power of the vibration motor according to the detected pressure. If a fault is found, the user is notified, which helps the user to understand the problem of the electric toothbrush in time and take measures to repair or replace the electric toothbrush in time, so as to maintain the brushing effect and user experience of the electric toothbrush.

[0009] In conjunction with some embodiments of the first aspect, in some embodiments, the electric toothbrush controls the vibration motor and display module according to a first decision and a second decision to make the difference between the vibration frequency of the current electric toothbrush head and the preset vibration frequency less than a preset vibration frequency threshold. This step specifically includes: the electric toothbrush reducing the output power of the vibration motor so that the difference between the vibration frequency of the current electric toothbrush head and the preset vibration frequency is less than the preset vibration frequency threshold; and the electric toothbrush displaying a prompt message through the display module, the prompt message being used to remind the user that the intensity level has been reduced.

[0010] By adopting the above technical solution, the electric toothbrush controls the output power of the vibration motor according to the first decision and the second decision. When the electric toothbrush reduces the output power of the vibration motor, it sends a prompt message to remind the user that the current speed of the electric toothbrush has been reduced. This can prevent the vibration motor from maintaining the original output power when the pressure on the electric toothbrush is too high, which would cause the vibration frequency to be too strong. It also reminds the user that the speed has been reduced, which helps to remind the user to reduce the pressure when brushing their teeth and avoid over-brushing.

[0011] In conjunction with some embodiments of the first aspect, in some embodiments, the electric toothbrush controls the vibration motor and display module according to a first decision and a second decision to make the difference between the vibration frequency of the current electric toothbrush head and the preset vibration frequency less than a preset vibration frequency threshold. This step specifically includes: the electric toothbrush increasing the output power of the vibration motor so that the difference between the vibration frequency of the current electric toothbrush head and the preset vibration frequency is less than the preset vibration frequency threshold; and the electric toothbrush causing the display module to display a prompt message to indicate to the user that the intensity level has been increased.

[0012] By adopting the above technical solution, the electric toothbrush controls the output power of the vibration motor according to the first decision and the second decision. When the electric toothbrush increases the output power of the vibration motor, it sends a prompt message to remind the user that the current level of the electric toothbrush has been increased. This can prevent the vibration motor from maintaining the original output power when the pressure on the electric toothbrush is too low, which would result in a too weak vibration frequency and affect the cleaning effect. The prompt message also reminds the user that the level has been increased, which helps to remind the user to increase the pressure when brushing to achieve the desired cleaning effect.

[0013] In conjunction with some embodiments of the first aspect, in some embodiments, after the electric toothbrush controls the vibration motor and display module according to the first decision and the second decision to make the difference between the vibration frequency of the current electric toothbrush head and the preset vibration frequency less than the preset vibration frequency threshold, the method further includes: within a preset detection time, the electric toothbrush detects the motion acceleration of the current electric toothbrush through an accelerometer; the electric toothbrush calculates the change frequency, change amplitude, and change duration of the motion acceleration based on the motion acceleration; the electric toothbrush determines whether the electric toothbrush is in a brushing state based on the change frequency, the change amplitude, and the change duration; if the electric toothbrush is in a brushing state, the electric toothbrush records the cumulative working time; when the cumulative working time is greater than the preset maximum brushing time, the electric toothbrush displays a second prompt message through the display module, the second prompt message being used to prompt the user to stop brushing.

[0014] By adopting the above technical solution, it is possible to determine whether the electric toothbrush is in brushing mode based on the frequency, amplitude, and duration of changes in the electric toothbrush's acceleration. If the electric toothbrush is in brushing mode, it is determined whether the maximum brushing time has been exceeded based on the cumulative working time of the electric toothbrush. If the maximum brushing time has been exceeded, the user is prompted to stop brushing. This helps users control their brushing time, as both excessively long and short brushing times may have adverse effects on oral health. Furthermore, determining whether the maximum brushing time has been exceeded only when the electric toothbrush is in brushing mode prevents inappropriate prompts from being sent when the electric toothbrush is in working mode but not brushing mode.

[0015] In conjunction with some embodiments of the first aspect, in some embodiments, the electric toothbrush determines whether it is in a brushing state based on the change frequency, the change amplitude, and the change duration. This step specifically includes: when the change frequency is within a preset change frequency range, the change amplitude is within a preset change amplitude range, and the change duration is greater than a preset change time threshold, the electric toothbrush determines that it is in a brushing state.

[0016] By adopting the above technical solution, the system can determine whether the electric toothbrush is in brushing mode based on the preset change frequency range, preset change amplitude range, and preset change time threshold. This allows for more accurate judgment of the brushing status and avoids sending inappropriate prompts when the electric toothbrush is in working mode but not in brushing mode.

[0017] In conjunction with some embodiments of the first aspect, in some embodiments, the electric toothbrush detects first pressure data through a motor pressure sensor. This step specifically includes: the electric toothbrush obtaining the resistance change of the motor pressure sensor according to a preset differential amplifier circuit; and the electric toothbrush determining the first pressure data based on the resistance change.

[0018] By adopting the above technical solution, the change in resistance of the motor pressure sensor can be obtained, which allows for more accurate measurement of the pressure between the motor sensor on the electric toothbrush head and the oral cavity contact surface.

[0019] Secondly, embodiments of this application provide a voltage stabilization system for an electric toothbrush, the voltage stabilization system comprising: a first detection module, a second detection module, a first determination module, a second determination module, and a control module.

[0020] The first detection module is used to detect the first pressure data through the motor pressure sensor; The second detection module is used to detect the second pressure data through the button pressure sensor; The first determining module is used to determine the first pressure data in the first gear of the preset motor pressure decision table and the second pressure data in the second gear of the preset button pressure table; The second determining module is used to determine the first decision of the first gear in the preset motor pressure decision table and to determine the second decision of the second gear in the preset button pressure table. The control module is used to control the vibration motor and the display module according to the first decision and the second decision, so that the difference between the vibration frequency of the current electric toothbrush head and the preset vibration frequency is less than the preset vibration frequency threshold.

[0021] Thirdly, embodiments of this application provide a voltage stabilization system for an electric toothbrush, the system comprising: one or more processors and a memory; the memory is coupled to the one or more processors, the memory being used to store computer program code, the computer program code including computer instructions, the one or more processors calling the computer instructions to cause the system to perform the method as described in the first aspect and any possible implementation thereof.

[0022] Fourthly, embodiments of this application provide a voltage regulation system readable storage medium for an electric toothbrush, including instructions that, when executed on a system, cause the system to perform the method described in the first aspect and any possible implementation thereof.

[0023] One or more technical solutions provided in the embodiments of this application have at least the following technical effects or advantages: 1. This application uses an electric toothbrush to control a vibration motor and a display module based on detected first and second pressure data. By changing the output power of the vibration motor, the vibration frequency of the electric toothbrush head can be kept stable and will not change due to changes in the pressure applied to the electric toothbrush. If the pressure applied to the electric toothbrush increases while the output power of the vibration motor remains unchanged, the vibration frequency will be too strong and will damage the teeth. By automatically adjusting the output power of the vibration motor according to the detected pressure, the cleaning effect of the electric toothbrush can be improved, damage to the gums and teeth can be reduced, and the user experience can be improved.

[0024] 2. This application, before the electric toothbrush detects the first pressure data, applies standard pressure to both the motor pressure sensor and the button pressure sensor. The electric toothbrush then determines whether the vibration motor is at a preset output power threshold when both sensors are under standard force. If it is not at the preset power threshold, the user is alerted that the electric toothbrush is faulty. This ensures that the electric toothbrush's function of adjusting the vibration motor to the correct output power based on the detected pressure is intact. If a fault is detected, the user is alerted, which helps the user understand the problem with the electric toothbrush in a timely manner and take measures to repair or replace the electric toothbrush, thus maintaining the brushing effect and user experience of the electric toothbrush.

[0025] 3. This application determines whether the electric toothbrush is in brushing mode based on the frequency, amplitude, and duration of changes in the electric toothbrush's acceleration. If the electric toothbrush is in brushing mode, it determines whether the maximum brushing time has been exceeded based on the cumulative working time of the electric toothbrush. If the maximum brushing time has been exceeded, the user is prompted to stop brushing. This helps users control their brushing time, as both excessively long and short brushing times may have adverse effects on oral health. Furthermore, determining whether the maximum brushing time has been exceeded only when the electric toothbrush is in brushing mode prevents inappropriate prompts from being sent when the electric toothbrush is in working mode but not brushing mode.

[0033] The terminology used in the following embodiments of this application is for the purpose of describing particular embodiments only and is not intended to be limiting of this application. As used in the specification and appended claims of this application, the singular expressions “a,” “an,” “the,” “the,” “the,” and “this” are intended to include the plural expressions as well, unless the context clearly indicates otherwise. It should also be understood that the term “and / or” as used in this application refers to and includes any or all possible combinations of one or more of the listed items.

[0034] Hereinafter, the terms "first" and "second" are used for descriptive purposes only and should not be construed as implying or suggesting relative importance or implicitly indicating the number of indicated technical features. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature, and in the description of the embodiments of this application, unless otherwise stated, "multiple" means two or more.

[0035] like Figure 1 The diagram shown is a flowchart illustrating a user's use of an electric toothbrush in the relevant technology of this application.

[0036] S101. The user turns on the electric toothbrush switch and adjusts it to the desired setting.

[0037] S102. The electric toothbrush adjusts the output power of the vibration motor according to the gear setting information.

[0038] S103. When the pressure applied by the user to the electric toothbrush increases, the output power of the electric toothbrush remains unchanged, causing the vibration frequency of the electric toothbrush to change.

[0039] Understandably, in related technologies, when the contact force between the brush head and teeth is too great, the pressure on the electric toothbrush increases. The electric toothbrush cannot adjust the output power of the vibration motor according to the increased pressure, which ultimately affects the cleaning effect and user experience of the electric toothbrush.

[0040] The above describes the user's method for using an electric toothbrush in the related technology of this application. The following will describe the voltage stabilization method for the electric toothbrush of this application.

[0041] like Figure 2 The diagram shown is an interactive scenario illustration of a voltage stabilization system for an electric toothbrush according to an embodiment of this application. The voltage stabilization system includes an electric toothbrush, which includes a brush head and a handle. The brush head is used to clean the oral cavity, and the handle is used by the user to grip it. A vibration motor and a motor pressure sensor are installed inside the brush head. The vibration motor is used to generate vibration to achieve a cleaning effect, and the motor pressure sensor is used to measure the pressure between the oral cavity contact surface and the brush head. A button pressure sensor is installed inside the handle of the electric toothbrush to detect the pressure generated when the user grips the handle. A display module is installed outside the handle to display the gear information and emit sound prompts.

[0042] The above is a schematic diagram of an interactive scenario of a voltage stabilization system for an electric toothbrush according to an embodiment of this application. The following is a combination of... Figure 3 The present application describes the voltage stabilization method for the electric toothbrush: like Figure 3 The diagram shown is a flowchart illustrating a voltage stabilization method for an electric toothbrush according to an embodiment of this application.

[0043] S301, the electric toothbrush detects the first pressure data through the motor pressure sensor.

[0044] The motor pressure sensor is installed at the brush head of the electric toothbrush. The output resistance value of the motor pressure sensor changes according to the pressure applied to the sensor. When the brush head comes into contact with the inside of the mouth, it will be subjected to force and deform, causing the output resistance value of the motor pressure sensor to change and generate an electrical signal. The electrical signal is then amplified by a differential amplifier circuit to obtain the first pressure data.

[0045] S302, the electric toothbrush detects a second pressure data through a button pressure sensor.

[0046] The button pressure sensor is installed on the handle of the electric toothbrush. When the user uses the electric toothbrush, pressure is applied to the handle. When the handle is subjected to force, the button pressure sensor is subjected to force and a change in the resistance value of the button pressure sensor is generated. Similar to the motor pressure sensor, the electrical signal generated by the change in resistance value is amplified by a differential amplifier circuit to obtain the second pressure data.

[0047] S303, The electric toothbrush determines the first pressure data in the first column of the preset motor pressure decision table and the second pressure data in the second column of the preset button pressure table.

[0048] The first pressure data is used to locate the corresponding first column in a preset motor pressure decision table. This preset motor pressure decision table is a data table pre-stored in the internal control unit of the electric toothbrush. The data table contains motor pressure data and the corresponding electric toothbrush output decision. The motor pressure data is range data, such as 5 Newtons to 5.5 Newtons per range, corresponding to one output decision. The decision includes the output power of the electric toothbrush's vibration motor. The second pressure data is used to locate the corresponding second column in a preset button pressure decision table. This preset button pressure decision table is also a data table pre-stored in the internal control unit of the electric toothbrush. It contains button pressure data and the corresponding electric toothbrush output decision. The button pressure data is range data, such as 4 Newtons to 4.5 Newtons per range, corresponding to one output decision. The decision includes the output power of the electric toothbrush's vibration motor.

[0049] S304, The electric toothbrush determines the first decision of the first column in the preset motor pressure decision table and determines the second decision of the second column in the preset button pressure table.

[0050] In some embodiments, the electric toothbrush output power in the preset motor pressure decision table is divided into multiple output levels, corresponding to different vibration motor output powers. For example, if the electric toothbrush has five working levels, and the current output power of the electric toothbrush in its working state is the first level, which is 5 watts, the first pressure data detected by the motor pressure sensor is 3.5 Newtons. The first decision corresponding to this first pressure data in the preset motor pressure decision table is to change the vibration motor output power to the third level, which is 4.2-4.8 watts. The electric toothbrush then determines this first decision. Similarly, the second pressure data detected by the button pressure sensor is 5 Newtons. The second decision corresponding to this second pressure data in the preset button pressure decision table is to change the vibration motor output power to the fourth level, which is 3-3.6 watts. The electric toothbrush then determines this second decision.

[0051] S305. The electric toothbrush controls the vibration motor and display module according to the first decision and the second decision, so that the difference between the vibration frequency of the electric toothbrush head and the preset vibration frequency is less than the preset vibration frequency threshold.

[0052] After determining the first and second decisions, if the vibration motor output power corresponding to the first and second decisions is the same, the electric toothbrush will execute the corresponding output power according to that level. If the vibration motor output power corresponding to the first and second decisions is different, the output power corresponding to the two decisions will be added together and averaged to calculate the vibration motor output power range. For example, in the example above, the first decision is to change the vibration motor output power to 4.2-4.8 watts, and the second decision is to change the vibration motor to 3-3.6 watts. The average of these two decisions will give a new output power range of 3. 6-4.2 watts, which is the fourth setting, means the electric toothbrush adjusts the vibration motor output power to the fourth setting and displays the current setting as the fourth setting on the display module, while also emitting a prompt sound. This ensures that the electric toothbrush head maintains the same vibration frequency as before the change in the first and second pressure data. In other words, the difference between the vibration frequency of the brush head and the preset vibration frequency is less than the preset vibration frequency threshold. The preset vibration frequency is the vibration frequency before the change in the first and second pressure data. This threshold indicates that the difference between the vibration frequency achieved after the electric toothbrush vibration motor changes its output power and the previous vibration frequency will remain within a small range.

[0053] It is understandable that when the output power of the vibration motor increases, the vibration frequency of the vibration motor increases.

[0054] In the above embodiments, the electric toothbrush controls the vibration motor and display module by detecting the first and second pressure data. The output power of the vibration motor is changed to keep the vibration frequency of the electric toothbrush head stable, so that the vibration frequency does not change due to changes in the pressure on the electric toothbrush. If the pressure on the electric toothbrush increases but the output power of the vibration motor remains unchanged, the vibration frequency will be too strong and will damage the teeth. By automatically adjusting the output power of the vibration motor according to the detected pressure, the cleaning effect of the electric toothbrush can be improved, damage to the gums and teeth can be reduced, and the user experience can be improved.

[0055] The above describes the scheme for an electric toothbrush to control the output power of the vibration motor and the display module based on the first and second pressure data. Below, we will combine this with... Figure 4 The following describes the proposed solution: like Figure 4 As shown, Figure 4 This is another schematic flowchart of a voltage stabilization method for an electric toothbrush according to an embodiment of this application.

[0056] S401. The electric toothbrush controls the vibration motor and display module according to the first decision and the second decision, so that the difference between the vibration frequency of the current electric toothbrush head and the preset vibration frequency is less than the preset vibration frequency threshold.

[0057] This step is similar to step S305, and will not be described again here.

[0058] S402. The electric toothbrush reduces the output power of the vibration motor so that the difference between the vibration frequency of the current electric toothbrush head and the preset vibration frequency is less than the preset vibration frequency threshold.

[0059] In some embodiments, when the output power of the electric toothbrush is at its maximum value at a certain moment, the first pressure data detected by the motor pressure sensor increases, and the second pressure data detected by the button pressure sensor increases. The electric toothbrush executes steps S303-S304 based on the first pressure data and the second pressure data, which reduces the output power of the vibration motor, so that the difference between the vibration frequency of the electric toothbrush head and the vibration frequency when the first pressure data and the second pressure data have not increased will be maintained within a small range.

[0060] S403. The electric toothbrush displays a prompt message through a display module, which is used to remind the user that the speed has been reduced.

[0061] When an electric toothbrush reduces the output power of its vibration motor, it updates the corresponding power level information via the display module and issues a prompt sound.

[0062] In the above embodiment, the electric toothbrush controls the vibration motor and display module according to the first decision and the second decision to make the difference between the current vibration frequency of the electric toothbrush head and the preset vibration frequency less than the preset vibration frequency threshold. This step specifically includes: the electric toothbrush reducing the output power of the vibration motor so that the difference between the current vibration frequency of the electric toothbrush head and the preset vibration frequency is less than the preset vibration frequency threshold; and the electric toothbrush displaying prompt information through the display module, which is used to remind the user that the intensity level has been reduced.

[0063] S404. Within a preset detection time, the electric toothbrush detects the current motion acceleration of the electric toothbrush using an accelerometer.

[0064] When an electric toothbrush is used by a user, it will generate a certain amount of motion acceleration due to displacement in different directions. An acceleration sensor can measure the motion acceleration of the electric toothbrush during use. The preset detection time is longer than the maximum brushing time set by the electric toothbrush. During the preset detection time, the electric toothbrush will detect whether the user is brushing their teeth.

[0065] S405. The electric toothbrush calculates the frequency, amplitude, and duration of the change in motion acceleration based on the motion acceleration.

[0066] If the electric toothbrush's acceleration changes irregularly when the user performs a brushing motion, the frequency of change refers to the frequency of acceleration changes during the brushing motion. If the frequency of acceleration changes is zero within the preset detection time range, the electric toothbrush is not in a brushing state. The amplitude of change refers to the magnitude of acceleration changes during the brushing motion. If the amplitude of acceleration changes is zero within the preset detection time range, the electric toothbrush is not in a brushing state. The duration of change refers to the length of the brushing motion, i.e., the duration of the brushing motion. This duration of change is the time difference between the start and end times of the acceleration change.

[0067] S406. When the change frequency is within a preset change frequency range, the change amplitude is within a preset change amplitude range, and the change duration is greater than a preset change time threshold, the electric toothbrush determines that it is in the brushing state.

[0068] In some embodiments, the brushing motion typically has a certain frequency, which causes the acceleration of the electric toothbrush to vary. When the frequency of this variation is between 50 and 300 times per minute, the amplitude of the variation is between 0.1 and 2 dm / s^2, and the duration of the variation is greater than 30 seconds, the electric toothbrush determines that it is in a brushing state. This data is obtained from a large number of experimental tests and is set in the control unit inside the electric toothbrush.

[0069] S407. If the electric toothbrush is in brushing mode, the electric toothbrush records the cumulative working time.

[0070] The cumulative working time is the total time the electric toothbrush is in brushing mode.

[0071] S408. When the cumulative working time exceeds the preset maximum brushing time, the electric toothbrush displays a second prompt message through the display module.

[0072] The maximum brushing time is the medically recommended optimal brushing time. Exceeding the optimal brushing time may cause damage to the oral mucosa. The maximum brushing time of an electric toothbrush is set in the internal control unit of the electric toothbrush. When the electric toothbrush detects that the cumulative working time exceeds the maximum brushing time, the electric toothbrush will issue a prompt message on the display module and issue a prompt sound message through the sound module.

[0073] In the above embodiments, the system determines whether the electric toothbrush is in brushing mode based on the frequency, amplitude, and duration of changes in the electric toothbrush's acceleration. If the electric toothbrush is in brushing mode, it determines whether the maximum brushing time has been exceeded based on the cumulative working time of the electric toothbrush. If the maximum brushing time has been exceeded, the user is prompted to stop brushing. This helps the user control the brushing time, as both excessively long and short brushing times may have adverse effects on oral health. Furthermore, determining whether the maximum brushing time has been exceeded only when the electric toothbrush is in brushing mode prevents inappropriate prompts from being sent when the electric toothbrush is in working mode but not brushing mode.

[0074] S409. The electric toothbrush increases the output power of the vibration motor so that the difference between the vibration frequency of the current electric toothbrush head and the preset vibration frequency is less than the preset vibration frequency threshold.

[0075] In some embodiments, when the output power of the electric toothbrush is at its minimum at a certain moment, the first pressure data detected by the motor pressure sensor decreases, the second pressure data detected by the button pressure sensor decreases, and the electric toothbrush executes steps S303-S304 according to the first pressure data and the second pressure data, which increases the output power of the vibration motor, so that the difference between the vibration frequency of the electric toothbrush head and the vibration frequency when the first pressure data and the second pressure data have not decreased will be maintained within a small range.

[0076] S410 The electric toothbrush causes the display module to display a prompt message to indicate to the user that the speed setting has been increased.

[0077] When an electric toothbrush increases the output power of its vibration motor, it updates the corresponding power level information via the display module and issues a prompt sound.

[0078] In the above embodiments, the electric toothbrush controls the output power of the vibration motor according to the first decision and the second decision. When the electric toothbrush increases the output power of the vibration motor, it sends a prompt message to remind the user that the current level of the electric toothbrush has been increased. This can prevent the vibration motor from maintaining the original output power when the pressure on the electric toothbrush is too low, which would result in a too weak vibration frequency and affect the cleaning effect. The prompt message also reminds the user that the level has been increased, which helps to remind the user to increase the pressure when brushing to achieve the desired cleaning effect.

[0079] The above describes the solutions for electric toothbrushes that modify the output power of the vibration motor and detect the brushing status. Next, we will combine... Figure 5 The following describes the proposed solution: like Figure 5 As shown, Figure 5 This is another schematic flowchart of a voltage stabilization method for an electric toothbrush according to an embodiment of this application.

[0080] S501, the electric toothbrush detects standard pressure data through a motor pressure sensor and a button pressure sensor.

[0081] When testing for malfunctions in an electric toothbrush, a standard pressure is applied to the toothbrush. This standard pressure is obtained from a large number of previous experiments. When the electric toothbrush is subjected to this standard pressure, the output power of the vibration motor should be the decision corresponding to the pressure data detected by the motor pressure sensor in the preset motor pressure decision table. This decision corresponds to the output power of the vibration motor.

[0082] In some embodiments, the electric toothbrush is placed on the clamp and a calibration switch plate is inserted. The calibration switch plate is used to give a specific charging signal to the charging port of the electric toothbrush so that the electric toothbrush enters the calibration mode. The switch on the calibration switch plate is triggered, and the electric toothbrush enters the calibration mode. At this time, the clamp is operated so that the electric toothbrush is subjected to standard pressure.

[0083] S502, The electric toothbrush determines whether the output power of the vibration motor is at the preset output power threshold.

[0084] In some embodiments, in the calibration mode of the electric toothbrush, the preset output power threshold is the output power of the vibration motor corresponding to the decision mentioned above. When the output power of the vibration motor is the preset output power threshold, the electric toothbrush is not faulty.

[0085] S503. If the power threshold is not preset, the electric toothbrush displays the first prompt information through the display module.

[0086] When the output power of the vibration motor is not at the preset output power threshold, the electric toothbrush is faulty and will issue a prompt message in the display module to alert the user that the electric toothbrush is faulty.

[0087] Understandably, when the electric toothbrush is in calibration mode, if the output power of the vibration motor is not at the preset output power threshold, the user can repeat the above steps to recalibrate the electric toothbrush after the electric toothbrush indicates a fault. This allows the user to perceive calibration failures caused by improper assembly or internal components of the electric toothbrush. If the output power of the vibration motor is at the preset output power threshold after the fault is resolved, the electric toothbrush will display a prompt message through the display module to inform the user that the electric toothbrush has been successfully calibrated and can work normally.

[0088] In the above embodiment, before the electric toothbrush detects the first pressure data, standard pressure is applied to the motor pressure sensor and the button pressure sensor of the electric toothbrush. The electric toothbrush determines whether the vibration motor is at the preset output power threshold when both sensors are under standard force. If it is not at the preset power threshold, the user is prompted that the electric toothbrush is faulty. This ensures that the electric toothbrush is functioning properly to change the output power of the vibration motor according to the detected pressure. If a fault is found, the user is notified, which helps the user to understand the problem with the electric toothbrush in time and take timely measures to repair or replace the electric toothbrush, thus maintaining the brushing effect and user experience of the electric toothbrush.

[0089] S504, The electric toothbrush obtains the resistance change of the motor pressure sensor according to a preset differential amplifier circuit.

[0090] The motor pressure sensor is installed at the brush head of the electric toothbrush. The output resistance value of the motor pressure sensor changes according to the pressure applied to the sensor. When the brush head comes into contact with the inside of the mouth, it will be subjected to force and deform, causing the output resistance value of the motor pressure sensor to change and generate an electrical signal. The electrical signal generated by the change in resistance value is amplified by a differential amplifier circuit.

[0091] S505, This electric toothbrush determines the first pressure data based on the change in resistance.

[0092] An electric toothbrush uses an analog-to-digital converter in its internal control unit to convert the electrical signal generated by the change in resistance into a digital signal, thus obtaining the first pressure data.

[0093] In the above embodiments, obtaining the change in resistance of the motor pressure sensor can more accurately measure the pressure between the motor sensor on the electric toothbrush head and the oral cavity contact surface.

[0094] S506, This electric toothbrush detects a second pressure data via a button pressure sensor.

[0095] S507, The electric toothbrush determines the first pressure data in the first column of the preset motor pressure decision table and the second pressure data in the second column of the preset button pressure table.

[0096] S508, The electric toothbrush determines the first decision of the first column in the preset motor pressure decision table and determines the second decision of the second column in the preset button pressure table.

[0097] S509, the electric toothbrush controls the vibration motor and display module according to the first decision and the second decision.

[0098] It is understandable that steps S506-S509 are similar to steps S302-S305, and will not be described again here.
