Embodiments of the present invention, as shown in fig. 1 to 4, provide a control method and apparatus for an electric toothbrush, an electronic device, and a non-transitory computer readable storage medium.
It will be appreciated that when the electric toothbrush is switched to the normal operating mode, the electric toothbrush enters the normal brushing mode, increasing the motor vibration frequency, increasing the duty cycle of the operating voltage or increasing the motor operating voltage; namely, controlling the motor to run according to the rotating speed corresponding to the normal working mode; or according to the vibration frequency and the swing amplitude corresponding to the normal working mode. When the electric toothbrush is switched to the anti-splashing mode, the vibration frequency of the motor is reduced, the duty ratio of the working voltage is reduced or the working voltage of the motor is reduced; namely, controlling the motor to run according to the rotating speed corresponding to the anti-splashing mode; or the device operates according to the vibration frequency and the swing amplitude corresponding to the anti-splashing mode. Those skilled in the art will appreciate that in the splash-proof mode the motor of the electric toothbrush operates in a milder mode to avoid splashing of water or toothpaste; in the normal working mode, the motor of the electric toothbrush operates according to the rotation speed, the vibration frequency, the vibration amplitude or the rotation amplitude required by tooth cleaning, so that the effect of tooth cleaning is achieved.
In accordance with one embodiment of the present invention, referring to fig. 1, there is provided a control method of an electric toothbrush, the method comprising:
s101, acquiring a pressure value of a brush head;
it will be appreciated that the pressure applied by the brush head to the teeth during use of the electric toothbrush may be detected by built-in sensors or techniques, which may include, but are not limited to, pressure sensors, spring-loaded sensors, and the like.
In an alternative embodiment, a pressure sensor may be embedded in the bottom or inside of the brush head to monitor the pressure applied to the brush head in real time, and the pressure sensor may sense the pressure applied to the teeth by the user and convert it into an electrical signal for measurement and analysis.
In an alternative embodiment, a spring or resilient element may be mounted between the base of the head or bristles which compress inwardly when pressure is applied by the user, and the amount of pressure applied to the head may be indirectly known by sensing the degree of deformation of the spring or resilient element.
In other embodiments, the pressure applied by the user can be estimated by using a built-in algorithm and vibration sensing technology through the vibration mode and frequency of the brush head, different vibration responses can be generated by different pressures, and the pressure level received by the brush head can be estimated through analysis of the vibration signals.
S102, when the pressure value is larger than a first preset pressure value, controlling the electric toothbrush to operate in a normal working mode;
it can be appreciated that in this embodiment, the electric toothbrush is operated in the anti-splash mode with a lower swing amplitude after being turned on, so as to prevent the toothpaste and water from splashing, and when the pressure value is detected to be greater than the first preset pressure value (for example, when the pressure value of the brush head is detected to be greater than or equal to 30g within 2 minutes), it is determined that the user starts brushing teeth by using the electric toothbrush, and at this time, the electric toothbrush is operated in the normal working mode so as to facilitate the user to brush teeth, and the swing amplitude of the brush head in the normal working mode is greater than the swing amplitude in the anti-splash mode.
Optionally, the step of determining whether the pressure value is greater than the first preset pressure value may be determined within a first preset time period after the power-on, for example, whether the pressure value of the brush head is greater than the first preset pressure value is detected within 2 minutes after the power-on, if the pressure value of the brush head is greater than the first preset pressure value within 2 minutes after the power-on, the electric toothbrush is switched to the normal working mode at this time, and if the pressure value of the brush head is always less than or equal to the first preset pressure value within 2 minutes after the power-on, the electric toothbrush can be turned off at this time, and energy is saved.
S103, acquiring a working load parameter of a motor;
it is understood that in the present embodiment, the workload parameter of the motor may be at least one of a current value, a current change rate, a voltage value, and a voltage change rate, that is, the workload parameter may be one or more of a current value, a current change rate, a voltage value, and a voltage change rate.
In an alternative embodiment, the workload parameters include a plurality of current values, current change rates, voltage values and voltage change rates, and by comprehensively considering the plurality of parameters, the brushing state of the user can be more comprehensively judged, feedback and control can be more accurately made, the judgment accuracy is improved, and errors are reduced.
The test shows that the electric toothbrushes with different duty ratios output current values under 50-350 g have a certain relation, and further find that under the condition of the same motor and the same duty ratio, the pressure value and the current value of the motor form a linear relation under the input condition of the optimal frequency point of the system, and the comparison relation between the pressure value and the current value of the motor, namely the load parameter-pressure corresponding relation, is obtained according to the value tested by the actual system and stored in the control chip, so that the actual state of brushing teeth of a user can be judged through the current value of the system.
In an alternative embodiment, the operating load of the motor includes a current value, and when the electric toothbrush is not pressed on the teeth, the motor is not affected by pressure from the teeth, the operating current of the motor is small, and at the moment, the motor keeps in an anti-splashing mode to work, and the motor has low frequency and low swing, so that the splashing of toothpaste and water can not occur. When the electric toothbrush is pressed on the teeth, the working current of the motor is obviously increased due to the influence of the pressure from the teeth. In this embodiment, when the obtained current value is less than or equal to the first preset current value, the electric toothbrush is controlled to switch from the normal operation mode to the splash-proof mode.
In an alternative embodiment, the brushing status of the user can also be determined by the rate of change of current. The current change rate refers to the ratio of the amount of change of the current occurring in a period of time to the time, and when the detected current change rate is less than or equal to a first preset current change rate, the electric toothbrush is controlled to switch to the anti-splash mode.
Alternatively, the brushing state of the user may be determined according to the voltage or the voltage change rate, which is not particularly limited in this embodiment.
And S104, controlling the electric toothbrush to be switched from the normal working mode to the anti-splashing mode under the condition that the working load parameter is smaller than the preset parameter threshold value.
In this embodiment, when the electric toothbrush is in the normal working mode and the working load parameter is detected to be smaller than the preset parameter threshold, it may be determined that the user uses the electric toothbrush to separate the brush head from the teeth at this time, and the user is ready to take out the brush head or move the electric toothbrush to the tooth area on the other side to brush the teeth, and at this time, the electric toothbrush may be switched to the anti-splash mode to prevent the brush head from being still in a higher swing after being taken out from the oral cavity, for example, when the obtained current value is smaller than or equal to the first preset current value, the electric toothbrush is controlled to switch from the normal working mode to the anti-splash mode.
According to one embodiment of the present invention, after controlling the electric toothbrush to switch from the normal operation mode to the splash preventing mode in the case that the workload parameter is smaller than the preset parameter threshold value, the method further comprises:
controlling the electric toothbrush to be closed under the condition that the working load parameter is continuously smaller than a preset parameter threshold value and the duration time is longer than a first preset duration time; and controlling the electric toothbrush to be switched to a normal working mode under the condition that the working load parameter is detected to be greater than or equal to a preset parameter threshold value within a first preset time period.
It can be understood that taking the example that the working load parameter includes a current value, after detecting that the current value is smaller than a first preset current value, switching the electric toothbrush to an anti-splashing mode, if the current value is continuously smaller than the first preset current threshold value within 2 minutes, the user can be considered to stop brushing teeth, and at the moment, the electric toothbrush is turned off to save energy and prolong the service life of a battery; if the detected current value is larger than or smaller than the first preset current threshold value within 2 minutes, the user needs more time to brush teeth, and the user can be provided with more sufficient brushing time by switching back to the normal working mode.
According to one embodiment of the invention, the method further comprises the step of determining a preset parameter threshold. Specifically, the method for determining the preset parameter threshold may include: acquiring historical brushing data of a user, and determining a pressure range of the user during brushing based on the historical brushing data; based on the pressure range, a preset parameter threshold is determined according to a preset parameter-brushing force correspondence.
It can be understood that the preset parameter threshold value can be preset, analyzed and determined according to brushing data of public users, and also can be determined and updated in real time according to brushing habits of different users so as to meet the use demands of different users in different periods.
In this embodiment, historical brushing data for a user using the electric toothbrush over a period of time may be obtained by recording or sensors or the like. These data may include pressure, current values, brushing duration, etc. at various points in time; analyzing the obtained historical brushing data, such as counting the average value, the maximum/minimum pressure value, the average current value, the maximum/minimum current value and the like in different time periods, and according to the data, the brushing habit and the behavior mode of the user can be obtained, and the pressure range applied by the user during normal brushing can be estimated; and according to the established load parameter-pressure correspondence, preset parameter thresholds are determined, and the thresholds can be adjusted according to individual differences (pressure division) of different users so as to ensure that the change of brushing force can be accurately reflected in a normal use range. For example, historical brushing data of the user for three days or one week in the past can be obtained and analyzed to obtain the brushing pressure range of the user in the last period of time, so as to determine the first preset current value, and the recent data of the user is continuously obtained to update the first preset current value, so that the recent brushing behaviors and habits of the user are better compounded, and the accuracy and the practicability of the control of the electric toothbrush are improved.
The actual brushing state of the user is that the first is that the user squeezes toothpaste and infiltrates the brush hair, and the pressure value detected by the brush head does not have great error; secondly, the user can have upper and lower values in different ranges due to gestures and directions in the tooth brushing process, and the range is approximately deviated by 40g, so that the user can possibly exit the medium-pressure mode to cause a pause; the third is that the user takes the toothbrush out halfway, but does not press to turn off the electric toothbrush, at which time the toothbrush does not exit the medium pressure mode, resulting in splattering of toothpaste.
In a specific embodiment, if historical brushing data of a user in a past period of time is analyzed, the average force of the user in the normal brushing process is 180g, the data of the user is collected by sorting, the pressure range (brushing force range) of the user in the process is found to be 140 g-220 g (the brushing force of the user is basically consistent with normal distribution, the pressure range in the normal brushing process of the user can be determined by selecting a proper confidence interval), at the moment, a current value A1 corresponding to a system under 140g can be read as a reference value for switching the electric toothbrush from a normal working mode to an anti-splashing mode, when the current value of the current working of the motor is less than or equal to A1, at the moment, the current user is judged to be separated from the toothbrush head or to be moved to a brushing area on the other side in preparation, at the moment, the system can briefly exit from the normal working mode, and when the system detects that the current value of the current working of the motor is more than or equal to A1, the system reenters into the normal working mode.
According to one embodiment of the present invention, further comprising: the first preset pressure value is modified based on the historical brushing data.
In this embodiment, based on analysis of historical brushing data of a user in a period of time in the past, a pressure range of a brushing head in a process of using the electric toothbrush by the user can be obtained, and then a suitable and accurate first preset pressure value is selected, when the pressure value of the brushing head reaches the first preset pressure value, the user can be considered to brush teeth from the moment, and the first preset pressure value is continuously corrected and updated based on a recent brushing habit of the user, so that the corrected first preset pressure value is ensured to more accord with the expectations and habits of the user, and the requirements of the user are more accurately adapted.
It will be appreciated that the first preset pressure value may also be modified by increasing or decreasing a fixed, inexpensive amount, or adaptively adjusted according to some algorithm.
According to one embodiment of the present invention, further comprising: and under the condition that the pressure value is greater than or equal to a second preset pressure value, controlling the electric toothbrush to switch to an overpressure mode, and sending a prompt message to a user.
In this embodiment, optionally, the swing amplitude in the overpressure mode may be equal to the swing amplitude in the normal working mode, and vibration reminding is performed at intervals; optionally, the swing in the overpressure mode may be smaller than the swing in the normal working mode to avoid damage to the teeth of the user due to the high swing state and to protect the health of the teeth and gums.
In some embodiments, after the electric toothbrush enters the overpressure mode, a prompt message can be sent to the user in a sound or vibration mode or the like to remind the user to reduce the brushing force, help the user avoid using excessive brushing force, reduce the damage to teeth and gums and maintain the health state of the oral cavity.
