The intelligent appliance can be an intelligent electric toothbrush, a tooth flushing device, a tooth polisher and other intelligent oral care appliances.

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, during the use of the electric toothbrush, it has been found that the pressure detection value is also interfered by a large pressure rebound phenomenon, which may occur during the brushing process of the user or 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. To solve the problem, an embodiment of the present invention provides a pressure data processing control method, which is as follows.

Fig. 2 is a schematic flow chart of a pressure data processing control method in an embodiment of the present application, which may be executed by an electric toothbrush, as shown in fig. 2, wherein a predefined basic pressure value exists in the electric toothbrush, and the method includes the following steps:

step S101, obtaining a preset critical value, and detecting a current pressure value.

Step S102, comparing the preset critical value with the pressure value, and judging whether the pressure value is larger than the preset critical value.

In this embodiment, the pressure sensor in the electric toothbrush suddenly detects a large pressure, which may cause a pressure value to rebound and change, so that when the user brushes teeth again, the detected pressure value acting on the toothbrush is inaccurate, and the current operating mode of the toothbrush cannot be accurately determined. Therefore, the controller of the electric toothbrush needs to detect the current pressure value by controlling the pressure sensor and compare the current pressure value with the acquired critical value to judge whether the pressure value is greater than the critical value or not and whether the pressure rebounds and changes or not, so that corresponding operation is carried out according to the currently judged condition to ensure that the subsequent toothbrush can more accurately determine the pressure acted on the electric toothbrush by a user and determine the current working mode of the electric toothbrush. The current pressure value is a pressure value obtained by a pressure sensor of the electric toothbrush in real time; the critical value is used for judging whether large pressure appears or not, if the pressure value of the electric toothbrush is detected to be larger than the pressure critical value, the large pressure appears, and the pressure rebounding change can occur after the large pressure disappears.

Optionally, the preset threshold value ranges from 400g to 600 g.

Optionally, the value of the preset critical value is 500 g.

Optionally, the intelligent toothbrush in the oral care implement comprises a handle and a brush head. 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, 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, since the force applied to the toothbrush by the user during normal tooth brushing needs to be determined by using the basic pressure value, that is, the pressure value sensed by the electric toothbrush when the user does not apply a pressure to the electric toothbrush, and 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 thus after the electric toothbrush is turned on, the basic pressure value cannot be accurately detected, that is, the pressure value sensed by the electric toothbrush when the user does not apply a pressure to the electric toothbrush, so that the controller of the electric toothbrush can collect pressure values at preset intervals before the electric toothbrush is not used, that is, according to the collected pressure values before the tooth brushing action is not performed, and carrying out equalization processing on the acquired pressure value to obtain an equalization value to determine a basic pressure value when the electric toothbrush is not used, so that the situations that the deviation of the basic pressure value is too large and the like are prevented, and the phenomenon that the force applied to the electric toothbrush by a user is inaccurate is detected. 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 requirement of a user, and is generally one hour; the pressure value is detected by the pressure sensor at intervals when the electric toothbrush is not brushing teeth.

Optionally, the equalization processing may be to obtain a base pressure value by calculating a mathematical expectation of each collected pressure value, or may be to obtain a base pressure value by calculating a variance of a first difference of each collected pressure value.

Optionally, for each cycle when the oral care implement is not in use, a pressure value collected for that cycle is calculated as the pressure value difference from the pressure value collected for the adjacent cycle.

And when the pressure difference value is larger than a preset difference value threshold value, removing the pressure values acquired in the period.

In this embodiment, when the electric toothbrush stays 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 oral care device is not used is too large. Therefore, the pressure value of each period when the oral cavity nursing device is not used can be collected, the pressure value collected in the period and the pressure value collected in the adjacent period are calculated to obtain the pressure difference value, if the pressure difference value is larger than the 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 oral cavity nursing device 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, the pressure value acquired when the electric toothbrush is started is used as the basic pressure value, and the pressure value acquired when the electric toothbrush is started is used as the basic pressure value before the user brushes teeth normally at present, so that if the pressure difference value is not more than the pressure difference value threshold, the pressure value acquired when the electric toothbrush is started is used as the basic pressure value.

And step S103, if the pressure value is larger than the preset critical value, judging the pressure change trend in the pressure rebound process.

In this embodiment, when the controller of the electric toothbrush determines that the pressure sensor detects that the pressure value is greater than the preset critical value inside the electric toothbrush, it is determined that a large pressure occurs, in order to prevent the pressure value that is greater than the critical value at present from disappearing, the rebound of the pressure value causes the deviation of the pressure value that is finally detected to act on the toothbrush, which affects the subsequent determination, the pressure change trend in the pressure rebound process needs to be determined, and thus, according to the pressure change trend in the pressure rebound process, whether the basic pressure value needs to be redefined is determined. 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 pressure rebound process is shown in fig. 3, fig. 3 is a graph of a pressure curve after a large pressure is generated, and the curve change process from t4 to t5 in fig. 3 is the pressure rebound process.

And step S104, if the judgment result shows that the pressure variation trend is in a decreasing trend, redefining the basic pressure value.

In this embodiment, the slope value changes in the pressure rebound process in a decreasing trend, which indicates that the user is not going on normal brushing, and the toothbrush may be in the splash-proof mode, and the brushing mode of the electric toothbrush may be turned off for the user, and the brushing mode includes the normal brushing mode and the 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.

As shown in fig. 4, by way of specific example and not limitation, fig. 4 is a pressure curve variation diagram of the pressure sensor for continuing the tooth brushing action after generating a large pressure in the normal tooth brushing process, F1 in fig. 4 is a basic pressure value, Δ F is the preset threshold value, F is a difference value between an average value of the pressure values and a basic pressure value F1, and t is an operating time of the electric toothbrush, it can be seen from the diagram that when the tooth brushing action is continued after generating a large pressure in the tooth brushing process, the detected current pressure value is higher, but the determination of the operating mode is not affected, and the slope value of the curve in the curve variation diagram in the rising process after detecting a large pressure shows an increasing trend, so that it is also explained that the user applies a force to the electric toothbrush again to continue the tooth brushing action after generating a large pressure and the large pressure disappears, the base pressure value may not need to be recalibrated. 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.

By way of specific example and not limitation, as shown in fig. 5, fig. 5 is a graph showing the pressure curve of a pressure sensor during normal brushing without brushing motion after generating a large pressure, f1 in fig. 5 is the basic pressure value, Δ F is the preset critical value corresponding to the actual force, F is the difference between the average value of the pressure values and the basic pressure value F1, t is the working time of the electric toothbrush, as can be seen from the figure, the change of the slope value of the curve in the curve change graph in the rising process after the huge pressure is detected shows a descending trend, which indicates that the tooth brushing action is not carried out after the huge pressure is generated in the tooth brushing process, at this moment, the tooth brushing action is supposed to be in the anti-splashing mode, however, due to the rebound effect, the detected current pressure value is higher, and the toothbrush is misjudged to enter the normal tooth brushing mode, so the basic pressure value needs to be calibrated again.

By way of specific example and not limitation, as shown in fig. 6, fig. 6 is a first pressure curve diagram after the pressure sensor generates a large pressure in the splash prevention mode, f1 in fig. 6 is the basic pressure value, Δ F is the preset critical value corresponding to the actual force, F is the difference between the average value of the pressure values and the basic pressure value F1, t is the working time of the electric toothbrush, as can be seen from the figure, the change of the slope value of the curve in the curve change graph in the rising process after the large pressure is detected shows a descending trend, which shows that the tooth brushing action is not carried out after the large pressure is generated in the splash-proof mode, although the judgment of the working mode is not influenced, however, the offset of the pressure value after springback cannot be accurately obtained, and the basic pressure value needs to be recalibrated in order to ensure that the pressure value acting on the toothbrush again after accurate detection can be achieved.

As shown in fig. 7, fig. 7 is a second pressure curve variation diagram after the pressure sensor generates a large pressure in the anti-splashing mode, wherein F1 in fig. 7 is a base pressure value, Δ F is the preset threshold value corresponding to the actual acting force, F is a difference between the 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 value of the curve in the curve variation diagram in the rising process after the large pressure is detected shows a decreasing trend, which indicates that the toothbrush does not perform the brushing action after the large pressure is generated in the anti-splashing mode, and the toothbrush should be in the anti-splashing mode.

Optionally, as shown in fig. 8, the step S103 of determining the pressure variation trend in the pressure rebounding process includes the following steps:

step S201, obtaining an initial period slope in the rebounding process and an end period slope in the rebounding process.

Step S202, comparing the slope of the initial period with the slope of the ending period.

Step S203, if the slope of the initial period is greater than that of the ending period, determining the pressure change trend to be the descending trend; and if the slope of the initial period is smaller than that of the ending period, determining that the pressure change trend is an increasing trend.

In this embodiment, in order to determine the pressure variation trend during the rebound process, the initial period slope and the ending period slope during the rebound process can be obtained, as shown in fig. 9 and 10, fig. 9 is a first pressure curve variation diagram of the rebound process after generating a large pressure, and fig. 10 is a second pressure curve variation diagram of the rebound process after generating a large pressure. The slope of the preset period after t4 including t4 in the aforementioned fig. 9 and 10 is the initial period slope, i.e., the slope in the [ t4, t4+ Δ t ] period; the slope of the preset period before t5 including t5 in the aforementioned fig. 9 and 10 is the end period slope, i.e., the slope in the [ t5- Δ t, t5] period. 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 that of the ending period, determining that the pressure change trend in the rebounding process is a decreasing trend, namely the pressure curve change in fig. 10, 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. 9 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. The Δ t for determining the preset time period may be set according to a user requirement, which is not limited herein.

Optionally, as shown in fig. 11, the step S103 of determining the pressure variation trend in the pressure rebounding process includes the following steps:

and S301, acquiring a pressure value at the middle moment in the rebounding process and a preset middle threshold value.

And step S302, comparing the pressure value at the middle moment with the middle threshold value.

Step S303, if the pressure value at the intermediate moment is greater than the intermediate threshold, determining that the pressure variation trend is the decreasing trend; and if the pressure value at the intermediate moment is smaller than the intermediate threshold, determining that the pressure change trend is an increasing trend.

In the present embodiment, in order to determine the pressure variation trend during the rebound process, the pressure value at the intermediate time during the rebound process and the preset intermediate threshold value may be obtained, as shown in fig. 9 and 10, where t0 in fig. 9 and 10 is the intermediate time and F0 in fig. 9 and 10 is_t0The pressure value at the intermediate time is taken. By comparing the pressure value at the intermediate time with the preset intermediate threshold value, that is, F0 in fig. 9 and fig. 10, 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. 10, and redefining the basic pressure value F1 after the current rebounding process is finished and the working state of normal tooth brushing is no longer performed; if the pressure value at the intermediate moment is less than the preset intermediate threshold value, determining the rebound processThe pressure trend is an increasing trend, i.e. the pressure curve in fig. 9, which shows the normal brushing operation will be continued after the current bounce process is finished.

Optionally, as shown in fig. 12, the step of redefining the base pressure value in step S104 includes the following steps:

and S401, collecting a pressure value after the rebound process is finished, and constructing a pressure data set.

And S402, carrying out equalization processing on the pressure data set to obtain an equalization value.

And S403, taking the equalization value as a new basic 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, when the pressure value is in the preset time period after t5 in fig. 9 and fig. 10, 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 that can represent the pressure data set, and the equalization value is used as a new basic pressure value, so that the toothbrush can determine the current mode by using the latest basic pressure value.

Optionally, the equalization processing includes determining an equalization value by calculating a mathematical expectation of the pressure data set, determining an equalization value by a median in the pressure data set, determining an equalization value by counting pressure values that occur most frequently, determining an equalization value by calculating a median or a mode of the pressure data set, and the like.

In the embodiment of the application, a preset critical value is obtained, and a current pressure value is detected; comparing the preset critical value with the pressure value, and judging whether the pressure value is greater than the preset critical value; if the pressure value is larger than the preset critical value, judging the pressure change trend in the pressure rebounding process; and if the judgment result shows that the pressure variation trend is a descending trend, redefining the basic pressure value. When the pressure value is judged to be larger than the preset critical value, the fact that the intelligent oral care implement is subjected to larger acting force is judged, the pressure change trend in the pressure rebounding process is judged, if the pressure change trend is in a decreasing trend, the fact that the intelligent electric toothbrush is temporarily stopped by a user is indicated, and the basic pressure value needs to be defined again. By detecting the large pressure and determining whether the basic pressure value needs to be redefined after judging the rebound tendency of the large pressure, the situation that the pressure value detected by the toothbrush pressure sensor deviates relative to the value detected before the large pressure is applied after the large pressure disappears, so that the pressure value detected during subsequent tooth brushing action and acting on the toothbrush deviates and the working mode of the electric toothbrush cannot be normally judged from the original basic pressure value can be avoided; and the condition that the electric toothbrush is in error or even cannot work to cause discomfort to a user due to the fact that the electric toothbrush cannot generate wrong indication information is also ensured.

In the implementation process of the present invention, it is also found that the detection result of the pressure sensor installed inside the electric toothbrush may generate a pressure value drift phenomenon due to the variation of external factors such as the working temperature of the electric toothbrush, the indoor temperature, etc., that is, the pressure detection value detected by the pressure sensor of the electric toothbrush under the temperature drift phenomenon may have a deviation of becoming higher or lower, as shown in fig. 13 and 14.

Fig. 13 is a graph showing the pressure detection value increase under temperature drift, wherein F1 is a basic pressure value, i.e. a pressure value to which the electric toothbrush is subjected when the user does not apply pressure to the electric toothbrush during the activation of the toothbrush, Δ F is a preset pressure threshold value, F is a difference between the average value of the pressure values and the basic pressure value F1, and t is an operating time of the electric toothbrush. It can be seen from fig. 13 that the current pressure value becomes higher than the pressure value shown in fig. 1, i.e. 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 greater than the predetermined pressure threshold value in the anti-spatter mode. 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. 14 is a graph showing the pressure detection value becomes lower under the temperature drift, and it can be seen from fig. 14 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 in the anti-spattering mode is larger than the preset pressure 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 understood by referring to fig. 13 and 14, 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. 13, the electric toothbrush, which should be in the splash-proof mode, may accidentally enter the brushing mode operating at the first vibration frequency when not receiving pressure due to the high detection value caused by the temperature drift. Conversely, as shown in FIG. 14, 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 not accurately judged due to the deviation of the pressure detection value of the pressure sensor caused by the temperature drift phenomenon, the invention also provides a control method for adjusting the vibration frequency based on the pressure, which comprises the following steps.

Optionally, the operating frequency of the electric toothbrush includes a first vibration frequency and a second vibration frequency, the electric toothbrush has a basic pressure value, and when the electric toothbrush operates at the second vibration frequency, the following steps are performed: collecting the current pressure value of the electric toothbrush at a first preset time interval to construct a first pressure data set; performing first equalization processing on the constructed first pressure data set of the electric toothbrush to obtain a first equalization value; and 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, 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. And then, performing first equalization processing on the first pressure data set, wherein the first equalization value is obtained by calculating the variance of the first-order difference in the first pressure data set, namely, calculating the difference between two adjacent current pressure values in the current pressure value set, and then calculating the variance of at least two difference values in the first pressure data set, so as to provide a data base for subsequent comparison and judgment. In some other preferred embodiments, the first equalization process may be performed by calculating a mathematical expectation, variance, standard deviation, median, mode, etc. of the first data set.

In general, when the electric toothbrush is always in motion in the normal tooth brushing mode, but 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, when the electric toothbrush operates at the second vibration frequency after being started, the method further comprises the following steps: acquiring a basic pressure value; collecting the current pressure value at a second preset time interval to construct a second pressure data set; performing second equalization processing on the second pressure data set to obtain a second equalization value; and calculating a difference value between the basic pressure value and the second equilibrium value, comparing the difference value with a preset pressure critical value, and controlling the electric toothbrush to work at the first vibration frequency if the difference value is greater than the preset pressure critical 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. The current pressure value of the electric toothbrush is acquired at a second preset time interval by using the pressure sensor, a current pressure value acquisition mode within a preset time period or a preset number of current pressure value acquisition modes can be set, so that a second pressure data set is constructed according to each acquired current pressure value, the second preset time can be set according to specific precision requirements of users, generally, 20ms is preferred, and the preset number can be set according to the specific precision requirements of the users, generally, 10 times is preferred.

When the user brushes teeth, the user may brush teeth forcefully sometimes, and then brushes teeth again after changing direction or changing position, so that the phenomenon that no force is applied to the electric toothbrush is caused, or the phenomenon that the force applied by the user is large or small when the force applied by the user is changed during the tooth brushing process, if the current pressure value is measured once, the comparison result is not accurate easily, so that the current pressure value can be detected once every a period of time, namely the current pressure value is detected at the second preset time interval, so that the second pressure data set is equalized, and a second equalization value is obtained to represent the current pressure value within a period of time, thereby improving the accuracy of the current pressure value.

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 compared with the first 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 action, 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 a first vibration frequency. The preset pressure critical value can be set according to the user requirement, and if the second equilibrium value is obtained by calculating the expected value, the value range of the preset pressure 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 pressure threshold value is generally in the range of 2 to 10, and preferably 3.

Alternatively, the second equalization processing may be to obtain a second equalization value by calculating a mathematical expectation of the data set, or may be to obtain the second equalization value by calculating a variance of a first-order difference of the data set.

Optionally, the reconstructing the base pressure value includes the following steps: performing third equalization processing on the first pressure data set to obtain a third equalization value; and 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 the determination of the electric toothbrush, so that the third equilibrium processing is performed on each current pressure value in the obtained first pressure data set to obtain a third equilibrium value, and the third equilibrium value is used as a new basic pressure value.

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 electric toothbrush may detect the current working time in real time because the user sometimes has a behavior of forgetting to turn off the working mode of the electric toothbrush, and if the current working time detected by the current electric toothbrush is greater than the preset time threshold, it indicates that the current user may forget to turn off the working mode of the electric toothbrush. Wherein, the working modes comprise a normal tooth brushing mode for vibrating at a first frequency and a splash-proof mode for vibrating at a second frequency.

Optionally, in the process of brushing teeth, the force applied to the teeth needs to be kept within a certain range, so that the teeth can be cleaned without being damaged, therefore, the difference between the real-time detected current pressure value and the basic pressure value of the electric toothbrush in the normal brushing mode can be determined through a preset time interval, a preset minimum difference threshold value and a preset maximum difference threshold value are established, and when the difference is smaller than the minimum difference threshold value, it is indicated that the force applied by the current user is too small, and the electric toothbrush needs to perform corresponding prompt operation; when the difference is larger than the maximum difference threshold, it indicates that the force applied by the current user is too large, and the electric toothbrush also needs to perform corresponding prompt operation, so that the user can apply corresponding force in time according to the corresponding prompt operation. Wherein, the minimum difference threshold and the maximum difference threshold are both larger than the pressure critical value.

In the embodiment of the application, when the intelligent oral care implement works at a second vibration frequency, the current pressure value of the intelligent oral care implement is collected at a first preset time interval, and a first pressure data set is constructed; performing a first equalization process on the constructed first pressure dataset of the intelligent oral care implement to obtain a first equalization value; and 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. When the intelligent oral care implement works, the current pressure value is collected at a first preset time interval, the collected current pressure value is subjected to first equalization processing, the accuracy of the current pressure value is improved, the first equalization value is compared with a preset fluctuation value, the current working mode of the intelligent oral care implement is determined, whether the basic pressure value needs to be redefined or not is determined according to the working mode, when the first equalization value is smaller than the preset fluctuation value, the situation that the current intelligent oral care implement is in a splash-proof mode, namely, the working mode of vibration is carried out at a second vibration frequency is explained, the basic pressure value needs to be redefined by the oral care implement, and therefore the fact that the current working mode can be accurately judged by the intelligent oral care implement according to the corrected basic pressure value is guaranteed.

It should be understood that, the sequence numbers of the steps in the foregoing embodiments do not imply an execution sequence, and the execution sequence of each process should be determined by its function and inherent logic, and should not constitute any limitation to the implementation process of the embodiments of the present application.
