The intelligent oral care implement can be a common oral care tool such as an intelligent electric toothbrush, a tooth rinsing device, a tooth polisher and the like.

In this embodiment, the electric toothbrush is specifically described as an implementation object, the electric toothbrush includes two operation modes during normal operation, one is a tooth brushing mode operating at a first vibration frequency, and the other is a splash-proof mode operating at a second vibration frequency lower than the first vibration frequency, and the pressure change during normal operation of the electric toothbrush is shown in fig. 1. As shown in fig. 1, the average value of the pressure values received by the toothbrush at the second vibration frequency is approximately equal to F1, and the average value of the pressure values received by the toothbrush at the first vibration frequency is always greater than F1+ deltaF. When the toothbrush is started, the toothbrush is firstly in the splash-proof working mode, if the pressure value received by the subsequent toothbrush is increased, and when the variation of the pressure value exceeds delta F, namely the difference between the average value of the pressure values and the basic pressure value F1 exceeds delta F, the toothbrush enters the tooth brushing mode which works at the first vibration frequency.

However, in the process of using the electric toothbrush, a pressure value drift phenomenon (temperature drift phenomenon) may occur in a detection result of the pressure sensor installed inside the electric toothbrush due to a change in external factors such as an operating temperature of the electric toothbrush, an indoor temperature, and the like, that is, a pressure detection value detected by the pressure sensor of the electric toothbrush under the temperature drift phenomenon may be shifted to be higher or lower, as shown in fig. 2 and 3.

Fig. 2 is a graph showing the pressure detection value increase under temperature drift, wherein F1 is a basic pressure value, i.e. a pressure value that the electric toothbrush is subjected to when the user does not apply pressure to the electric toothbrush when the toothbrush is started, Δ F is a preset threshold value, F is a difference between the average value of the pressure values and the basic pressure value F1, and t is the operating time of the electric toothbrush. It can be seen from fig. 2 that the current pressure value becomes higher than the pressure value shown in fig. 1, that is, the temperature drift causes the pressure value to shift upwards, which results in the difference between the average value of the current pressure value and the actual base pressure value F1 being compared in the anti-splashing mode being greater than the predetermined threshold value. Normally, the electric toothbrush should be in the splash-proof mode, but the electric toothbrush may be accidentally put into the brushing mode due to temperature drift, i.e., the electric toothbrush should operate at the second vibration frequency, but may be erroneously controlled to operate at the first vibration frequency.

Fig. 3 is a graph showing the pressure detection value becomes lower under the temperature drift, and it can be seen from fig. 3 that the current pressure value becomes lower than the pressure value shown in fig. 1, that is, the temperature drift causes the pressure value to shift downwards, which results in that the difference (absolute value) between the current pressure value and the actual base pressure value to be compared under the anti-splashing mode is larger than the preset threshold value. Normally, the electric toothbrush should be in the splash-proof mode, but the temperature drift may cause the electric toothbrush to accidentally enter the brushing mode (although the pressure detection value is reduced), i.e., the electric toothbrush should operate at the second vibration frequency, but may be erroneously controlled to operate at the first vibration frequency. In addition, when the user wants to brush teeth, the user can brush teeth with almost the same force as usual, but the pressure detection value is lower as a whole due to the temperature drift, so that the electric toothbrush still works at the second vibration frequency.

As can be seen from fig. 2 and 3, the electric toothbrush should be in the splash-proof mode in some cases, that is, the electric toothbrush should be in the tooth brushing mode in which the electric toothbrush vibrates at the second vibration frequency, but when the temperature drift phenomenon occurs, the detection value detected by the pressure sensor may be shifted. As shown in fig. 2, the electric toothbrush, which should be in the splash-proof mode, may accidentally enter the brushing mode operating at the first vibration frequency when no pressure is applied thereto, due to the high detection value caused by the temperature drift. Conversely, as shown in FIG. 3, temperature drift results in a lower test value, requiring a greater force than usual to place the toothbrush in brushing mode.

Aiming at the problem that the working mode of the electric toothbrush is inaccurate in judgment due to the fact that the temperature drift phenomenon causes the deviation of the pressure detection value of the pressure sensor, the invention provides a control method for adjusting the vibration frequency based on pressure, and the control method is concretely implemented as follows.

Fig. 4 is a flow chart illustrating a control method for adjusting a vibration frequency based on pressure according to an embodiment of the present application, in which an execution body of the method may be an electric toothbrush, as shown in fig. 4, an operating frequency of the electric toothbrush includes a first vibration frequency and a second vibration frequency, a base pressure value exists in the electric toothbrush, and when the electric toothbrush operates at the second vibration frequency, the following steps are performed:

step S101, collecting the current pressure value of the electric toothbrush at a first preset time interval, and constructing a first pressure data set.

In this embodiment, the current pressure values of the electric toothbrush are acquired by using the pressure sensor at a first preset time interval, and a current pressure value acquisition manner within a preset time period or a preset number of current pressure value acquisition manners may be set, so as to construct a first pressure data set according to each acquired current pressure value, where the first preset time may be set according to a specific precision requirement of a user, and is preferably 20ms generally.

Step S102, performing first equalization processing on the constructed first pressure data set of the electric toothbrush to obtain a first equalization value.

In this embodiment, the first equalization processing on the first pressure data set may be performed by calculating a variance of a first-order difference in the first pressure data set, that is, calculating a difference between two adjacent current pressure values in a current pressure value set, and then calculating a variance of at least two differences in the first pressure data set, so as to obtain the first equalization value, thereby providing a data basis for subsequent comparison and determination. In some other preferred embodiments, the first equalization process may be performed by calculating a variance, a standard deviation, etc. of the first data set.

Step S103, comparing the first equilibrium value with a preset fluctuation value, and redefining the basic pressure value if the first equilibrium value is smaller than the preset fluctuation value.

In this embodiment, under normal conditions, the electric toothbrush is always moving in the normal brushing mode, when the electric toothbrush is not in the normal tooth brushing mode, the fluctuation of the electric toothbrush is relatively stable, namely the fluctuation value is small, therefore, the variation value of the determined pressure value fluctuation, namely the first equalization value, is compared with the preset fluctuation value, further judging the current state, if the first equilibrium value is smaller than the preset fluctuation value, the electric toothbrush is still in the anti-splashing mode, namely, in the working mode of vibrating at the second vibration frequency, because the temperature drift phenomenon occurs after the toothbrush is started for a period of time, therefore, the base pressure value F1 defined when the toothbrush is turned on may no longer be suitable for the pressure detection value that has deviated, so the base pressure value needs to be redefined, so as to ensure the correct judgment of the working mode of the toothbrush and avoid the condition of misjudgment caused by the influence of the temperature drift condition. It will be appreciated that if the first equalization value is greater than the predetermined fluctuation value, it indicates that the current mode of operation is the brushing mode, i.e. the user is performing a brushing action. The preset fluctuation value can be an integer within the range of [2, 10] according to specific precision requirements. The aforementioned preset fluctuation value is preferably set to 3. The larger the preset fluctuation value is, the more times the calibration is performed with respect to the base pressure value.

By way of specific example and not limitation, the user may set to obtain each current pressure value within 0.6s, and obtain the current pressure values at a frequency of every 20ms, that is, obtain 30 current pressure values, to form a current pressure value set, and if the value of the current pressure value set is (20001, 20002, 20003, 20004, 20005, 20007, 20008, 20007, 20005, 20006, 20006, 20007, 20006, 20008, 20009, 20008, 20006, 20007, 20009, 20006), the fluctuation variation value obtained by the pressure value set is smaller than the fluctuation threshold value 3, so as to perform anti-spattering control, that is, in an operation mode in which the electric toothbrush vibrates at the second vibration frequency; if the value of the current pressure value set is (20334, 20339, 20332, 20318, 20308, 20305, 20312, 20318, 20313, 20302, 20290, 20286, 20294, 20311, 20323, 20328, 20315, 20274, 20235, 20215, 20205, 20210, 20230), the fluctuation value obtained by the pressure value set is greater than the fluctuation threshold value 3, so that the normal brushing control is performed, that is, the electric toothbrush is in the operation mode of vibrating at the first vibration frequency.

Optionally, the intelligent toothbrush of the aforementioned intelligent oral care implement comprises a handle and a brushhead. The handle includes the shell and sets up the drive arrangement in the shell, and drive arrangement's output shaft stretches out the shell, and just aforementioned brush head can be installed on aforementioned output shaft through the mode of dismantling to make drive arrangement during operation utilize the output shaft to drive the brush head and shake with the mode of predetermineeing, so that the user brushes the tooth and moves. The intelligent toothbrush further comprises a pressure sensor, the pressure sensor can be arranged on the output shaft and can also be arranged on the brush head, the first coil is arranged on the brush head, the second coil is arranged on the handle, power supply between the pressure sensor on the brush head and the handle and transmission operation of related signals are achieved through the first coil and the second coil, namely, energy supply and data transmission between the pressure sensor and the handle are achieved through a device similar to a radio frequency tag arranged between the pressure sensor and the handle.

Optionally, as shown in fig. 5, when the electric toothbrush is operated at the second vibration frequency after being started, the method further comprises the following steps:

and step S201, acquiring a basic pressure value.

In this embodiment, the pressure sensor inside the electric toothbrush detects a certain pressure value due to some external factors, and the pressure value is a pressure value before the user does not perform the tooth brushing action.

Step S202, collecting the current pressure value at a second preset time interval, and constructing a second pressure data set.

In this embodiment, by using the pressure sensor to collect the current pressure values of the electric toothbrush at a second preset time interval, a current pressure value collection manner within a preset time period or a preset number of current pressure value collection manners may be set, so as to construct a second pressure data set according to each collected current pressure value, the second preset time may be set according to a user specific precision requirement, and is preferably 20ms in general, and the preset number may be set according to the user specific precision requirement, and is preferably 10 times in general.

And step S203, performing second equalization processing on the second pressure data set to obtain a second equalization value.

In this embodiment, when the user brushes teeth, the user may sometimes brush teeth with force, and sometimes brush teeth again after changing the direction or changing the position, which may result in no force being applied to the electric toothbrush, or when the force applied by the user during brushing teeth is large or small, if the current pressure value is measured once for subsequent comparison, the comparison result is easily inaccurate, so that the current pressure value may be detected once at intervals, that is, the current pressure value is detected at the second preset time interval, so as to obtain a second pressure data set, and the second pressure data set is equalized, so as to obtain a second equalization value, which represents the current pressure value within a period of time, thereby improving the accuracy of the current pressure value. Alternatively, the second equalization process may be a process of calculating a mathematical expectation of the data set to obtain a second equalization value.

Step S204, calculating a difference value between the basic pressure value and the second equilibrium value, comparing the difference value with a preset critical value, and if the difference value is greater than the preset critical value, controlling the electric toothbrush to work at the first vibration frequency.

In this embodiment, the difference between the first equilibrium value and the second equilibrium value is obtained by subtracting the obtained base pressure value, and the variation of the electric toothbrush from a starting base pressure value is determined by the difference. If the difference is greater than the predetermined threshold, it indicates that the user is currently performing normal brushing, so the controller of the electric toothbrush can control the electric toothbrush to enter a normal brushing mode, i.e., a working mode of vibrating at the first vibration frequency. The preset critical value can be set according to the specific precision requirement of a user, and if the second equilibrium value is obtained by calculating the expected value, the value range of the preset critical value is generally in the range of 18 to 28, and is preferably 20; if the second equalization value is obtained by calculating the variance of the first order difference, the value range of the preset threshold value is generally in the range of 2 to 10, and preferably 3.

Optionally, as shown in fig. 6, the step of redefining the base pressure value in step S103 includes the following steps:

step S301, performing third equalization processing on the first pressure data set to obtain a third equalization value.

And step S302, taking the third equalization value as a new basic pressure value.

In this embodiment, when the calculated first equilibrium value is smaller than the preset fluctuation value, it indicates that the electric toothbrush is not in the normal tooth brushing mode, and when the electric toothbrush is in the anti-splashing control mode, the basic pressure value needs to be determined again, so as to update data in real time and ensure that the electric toothbrush determines the working mode.

Alternatively, the third equalization process may be to calculate a mathematical expectation to obtain a third equalization value, that is, the new base pressure value.

Optionally, the basic pressure value is a pressure value collected when the electric toothbrush is started.

Optionally, the basic pressure value is a pressure value collected every preset period when the electric toothbrush is not used.

In this embodiment, when the user uses the electric toothbrush at ordinary times, there may be a phenomenon that the brush head of the electric toothbrush is pressed on the teeth before the electric toothbrush is turned on, so as to apply a certain force to the electric toothbrush, and therefore, after the electric toothbrush is turned on, the basic pressure value, that is, the pressure value sensed by the electric toothbrush when the user does not apply the pressure to the electric toothbrush, cannot be accurately detected, so that the controller of the electric toothbrush can collect the pressure value at intervals of a preset period before the electric toothbrush is not used, that is, the electric toothbrush does not perform the tooth brushing action, and then perform the equalization processing on the collected pressure value according to the collected pressure value before the tooth brushing action, so as to obtain the equalization value to determine the basic pressure value when the electric toothbrush is not used, thereby preventing the situation that the deviation of the basic pressure value is too large, and the like, thereby causing an inaccurate detection of the force applied by the user to the electric toothbrush. The preset period is a time interval obtained by the pressure value when the electric toothbrush is not used, and can be specifically set according to the specific precision requirement of a user, and generally one hour is preferred; the pressure value is detected by the pressure sensor at intervals when the electric toothbrush is not brushing teeth.

Alternatively, the equalization process may be to calculate a mathematical expectation of the collected pressure values to obtain a base pressure value.

Optionally, for each cycle when the intelligent oral care implement is not in use, a pressure difference value between the pressure value collected in the cycle and the pressure value collected in the adjacent cycle is calculated.

In this embodiment, when the electric toothbrush is stopped at some position, a sudden fall may occur, or some object may press on the electric toothbrush, so that the pressure value measurement is inaccurate, and finally, the deviation of the base pressure value when the intelligent oral care implement is not used is too large. Therefore, the pressure value of each period when the intelligent oral care implement is not used can be collected, the pressure difference value between the pressure value collected in the period and the pressure value collected in the adjacent period is calculated, if the pressure difference value is larger than a preset difference threshold value, the situation that the pressure value is changed sharply due to external factors when the pressure value is collected in the current period is shown, and therefore the pressure value collected in the period is removed, and the accuracy of the basic pressure value when the intelligent oral care implement is not used is improved. The preset difference threshold refers to a pressure value with the largest possible difference between pressure values for ensuring the accuracy of the basic pressure value, and if the preset difference threshold is larger than the maximum possible difference pressure value, it is indicated that the pressure value collected in the period is changed sharply due to some external factors.

Optionally, when the user uses the electric toothbrush at ordinary times, the brush head of the electric toothbrush may be pressed on the teeth before the electric toothbrush is turned on, so that a certain acting force is applied to the electric toothbrush, and therefore, after the electric toothbrush is turned on, a basic pressure value cannot be accurately detected, that is, a pressure value sensed by the electric toothbrush when the user does not apply pressure to the electric toothbrush, so that the basic pressure value determined by the pressure value acquired when the electric toothbrush is turned on can be compared with the basic pressure value determined by the pressure value acquired every preset period when the electric toothbrush is not used, and a pressure difference value is calculated, if the pressure difference value is greater than a pressure difference value threshold, it is indicated that the basic pressure value determined by the pressure value acquired when the electric toothbrush is turned on is too large, the electric toothbrush may be in a stage of being placed on the teeth, so that the pressure value acquired when the electric toothbrush is turned on cannot be used as the basic pressure value, and the pressure value collected every preset period when the electric toothbrush is not used is taken as a basic pressure value so as to improve the accuracy of the basic pressure value. If the pressure difference value is smaller than or equal to the pressure difference value threshold value, the pressure value collected when the electric toothbrush is started is used as the basic pressure value, and the pressure value collected when the electric toothbrush is started is the basic pressure value most suitable for the user before the user brushes teeth normally at present, so that if the pressure difference value threshold value is not exceeded, the pressure value collected when the electric toothbrush is started is used as the basic pressure value.

In the implementation process of the invention, the phenomenon of large pressure rebound is also found to cause interference on the pressure detection value, and the phenomenon of large pressure can occur in the process of brushing teeth by a user and can also occur when the toothbrush head is accidentally pressed or collided with a hard object. When the toothbrush head is subjected to a large pressure, due to the characteristics of the materials, the toothbrush head has a pressure rebound process after the pressure source disappears, and the rebound pressure can deviate from the pressure before the rebound. This deviation causes the detection value to be higher or lower. The working mode judgment of the toothbrush can be influenced when a large pressure rebound phenomenon occurs. In order to solve the problem, the invention further provides a control method for eliminating the pressure rebound interference, which comprises the following specific steps.

Acquiring a preset pressure critical value and detecting a current pressure value; comparing the preset pressure critical value with the pressure value, and judging whether the pressure value is greater than the preset pressure critical value; if the pressure value is larger than the preset pressure critical value, judging the pressure change trend in the pressure rebound process; if the judgment result shows that the rebound pressure variation trend is in a decreasing trend, the basic pressure value is redefined.

In this embodiment, when the pressure sensor in the electric toothbrush suddenly detects a large pressure, the pressure value may be rebounded, so that when the user again brushes teeth, the detected pressure value acting on the toothbrush is inaccurate, and the current working mode of the toothbrush cannot be accurately determined. Therefore, the controller of the electric toothbrush needs to detect the pressure value by controlling the pressure sensor and compare the pressure value with the acquired pressure critical value to judge whether the pressure value is greater than the pressure critical value or not and whether the phenomenon of pressure rebound change occurs or not, so that corresponding operation is performed according to the currently judged condition to ensure that the pressure acted on the electric toothbrush by a user is more accurately determined by the subsequent toothbrush, and the current working mode of the electric toothbrush is determined. When the controller of the electric toothbrush judges that the pressure value detected by the pressure sensor is greater than the preset pressure critical value in the electric toothbrush, the occurrence of high pressure is determined, and in order to prevent the pressure value which is greater than the pressure critical value at present from disappearing, the rebound of the pressure value causes the deviation of the pressure value finally detected to act on the toothbrush, so that the subsequent judgment is influenced, the pressure change trend in the pressure rebound process needs to be judged, and therefore whether the basic pressure value needs to be redefined or not is determined according to the pressure change trend in the pressure rebound process. If the pressure variation trend in the rebound process is a descending trend, the normal tooth brushing working state is not performed after the current rebound process is finished; if the pressure change trend in the rebound process is an increasing trend, the normal tooth brushing working state is continued after the current rebound process is finished. The change of the slope value in the process of the pressure rebound presents a descending trend, which indicates that the user does not continue normal tooth brushing action, at this time, the toothbrush can be in the splash-proof mode, and the tooth brushing mode of the electric toothbrush can be switched off for the user, and the tooth brushing mode comprises a normal tooth brushing mode and a splash-proof mode. And when judging that the current user does not carry out normal tooth brushing action, in order to accurately determine the force of the user acting on the toothbrush subsequently, the basic pressure value needs to be adjusted so as to determine a more accurate basic pressure value. The pressure value is obtained by a pressure sensor of the electric toothbrush in real time; the pressure critical value is used to determine whether a large pressure occurs, if it is detected that the pressure value of the electric toothbrush is greater than the pressure critical value, it indicates that the large pressure occurs, and a pressure rebound change occurs after the large pressure disappears, where the pressure rebound process is shown in fig. 7, fig. 7 is a pressure curve change diagram after the large pressure occurs, and a curve change process from t4 to t5 in fig. 7 is the pressure rebound process.

The basic pressure value is a pressure value sensed by a pressure sensor of the electric toothbrush when the user does not apply pressure to the electric toothbrush, and the acting force applied to the electric toothbrush by the user in the tooth brushing process can be determined through the basic pressure value. The electric toothbrush can cause the pressure sensor in the electric toothbrush to detect a certain pressure value due to some external factors, and the pressure value is the pressure value before the user does not brush teeth, so that the accuracy of the pressure applied when the user brushes teeth is ensured, and the accuracy of the basic pressure value is ensured; the preset critical value corresponding to the actual acting force is used for comparing the force exerted on the toothbrush to judge the current mode of the toothbrush, and the force exerted on the toothbrush by the user can be obtained through the basic pressure value and the pressure value detected by the pressure sensor in real time.

As shown in fig. 11, fig. 11 is a second pressure curve variation diagram after the pressure sensor generates a large pressure in the anti-splashing mode, where F1 in fig. 11 is a base pressure value, Δ F is the preset threshold corresponding to the actual force, F is a difference between an average value of the pressure values and the base pressure value F1, and t is an operating time of the electric toothbrush, as can be seen from the diagram, a slope of a curve in a rising process after the large pressure is detected in the curve variation diagram shows a decreasing trend, which indicates that the toothbrush does not perform a brushing action after the large pressure is generated in the anti-splashing mode, and the toothbrush should be in the anti-splashing mode.

And comparing the slope of the initial period with the slope of the end period to judge the pressure change trend in the current rebound process. If the slope of the initial period is greater than or equal to the slope of the ending period, determining that the pressure variation trend in the rebound process is a decreasing trend, namely the pressure curve variation in fig. 13, and redefining the basic pressure value F1 at this time; if the slope of the initial period is smaller than that of the ending period, the pressure change trend in the rebound process is determined to be an increasing trend, that is, the pressure curve in fig. 12 changes, which indicates that the normal tooth brushing operation will be continued after the current rebound process is ended, and at this time, the base pressure value does not need to be redefined.

By comparing the pressure value at the intermediate time with the preset intermediate threshold value, that is, F0 in fig. 12 and 13, the pressure variation trend in the current rebound process is judged by comparing the two. If the pressure value at the intermediate moment is greater than the preset intermediate threshold value, determining that the pressure variation trend in the rebounding process is a decreasing trend, that is, the pressure curve variation in fig. 13, which indicates that after the current rebounding process is finished, the working state of normal tooth brushing is no longer performed, and redefining the basic pressure value F1; if the pressure value at the intermediate time is smaller than the preset intermediate threshold, the pressure change trend in the rebound process is determined to be an increasing trend, that is, the pressure curve change in fig. 12, which indicates that the normal tooth brushing operation is continued after the current rebound process is finished.

Optionally, the redefining the base pressure value includes: collecting pressure values after the rebound process is finished, and constructing a pressure data set; carrying out equalization processing on the pressure data set to obtain an equalization value; the equalization value is used as a new base pressure value.

In this embodiment, after the pressure value tends to be stable, the basic pressure value is determined by the currently monitored pressure value in real time, so that the basic pressure value is more accurate, when the rebound process is finished, that is, when the change of the current pressure value tends to be stable, that is, the pressure value in the preset time period after t5 in fig. 12 and 13, the pressure value acquired in the preset time period is used to construct a pressure data set, and the pressure data set is subjected to equalization processing to obtain an equalization value capable of representing the pressure data set, and the equalization value is used as a new basic pressure value, so that the toothbrush determines the current mode by using the latest basic pressure value.

Wherein, the minimum difference threshold and the maximum difference threshold are both larger than the critical value.
