It is to be understood that the data so used is interchangeable under appropriate circumstances such that the embodiments of the invention described herein are capable of operation in sequences other than those illustrated or described herein. Furthermore, the terms "comprises," "comprising," and "having," and any variations thereof, are intended to cover a non-exclusive inclusion, such that a process, method, system, article, or apparatus that comprises a list of steps or elements is not necessarily limited to those steps or elements expressly listed, but may include other steps or elements not expressly listed or inherent to such process, method, article, or apparatus.

Example 1

There is provided, in accordance with an embodiment of the present invention, an embodiment of a method for controlling an electric toothbrush, it being noted that the steps illustrated in the flowchart of the drawings may be carried out in a computer system such as a set of computer executable instructions and that, although a logical order is illustrated in the flowchart, in some cases, the steps illustrated or described may be carried out in an order different than that which is presented herein.

Fig. 1 is a flowchart of a method of controlling an electric toothbrush according to an embodiment of the present invention, as shown in fig. 1, the method including the steps of:

step S102, obtaining a brush handle bending index of the electric toothbrush and a target reference pressure value of the electric toothbrush;

step S104, determining a target measured pressure value of the electric toothbrush based on the bending index of the brush handle;

step S106, determining a first difference value between a target measured pressure value and a target reference pressure value;

step S108, determining a target vibration mode of the electric toothbrush corresponding to the first difference value from the target comparison table;

step S110, determining a target power intensity of a target motor in the electric toothbrush according to the target vibration mode;

and step S112, determining a target working frequency and a target duty ratio of a target motor in the electric toothbrush according to the target power intensity so as to adjust the working frequency and the duty ratio of the target motor to the target working frequency and the target duty ratio.

Through the steps, the bending index of the brush handle of the electric toothbrush and the target reference pressure value of the electric toothbrush are obtained, the target measured pressure value of the electric toothbrush is determined based on the bending index of the brush handle, and then a first difference value between the target measured pressure value and the target reference pressure value is determined; determining a target vibration mode of the electric toothbrush corresponding to the first difference value from a target comparison table, wherein the target comparison table stores a corresponding relation between the difference value interval and the vibration mode; determining a target power level of a target motor in the electric toothbrush based on the target vibration pattern; and determining a target working frequency and a target duty ratio of a target motor in the electric toothbrush according to the target power strength so as to adjust the working frequency and the duty ratio of the target motor to the target working frequency and the target duty ratio. Since the target vibration pattern of the electric toothbrush is determined based on the target map and the first difference, the determined target measured pressure value is determined based on the actual operation of the electric toothbrush, not based on the time interval. The target vibration mode determined by the method can be determined more adaptively, so that the determined target vibration mode takes the actual use condition of the user into consideration. Because the target power strength is determined according to the target vibration mode, and then the target working frequency and the target duty ratio of the target motor in the electric toothbrush are determined, the target working frequency and the target duty ratio correspond to the target vibration mode, the determined target vibration mode can be achieved, the toothbrush vibration mode is determined by combining with the actual use condition of a user, and the technical effects of improving the cleaning efficiency and the user experience are achieved.

As an alternative embodiment, the handle bending index of the electric toothbrush and the target reference pressure value of the electric toothbrush are obtained; a target measured pressure value for the electric toothbrush is determined based on the handle bend index. For example, a pressure sensor can be arranged on a brush handle of the electric toothbrush, when a user brushes the teeth by using the electric toothbrush, the brush handle of the electric toothbrush is bent due to stress, and the pressure sensor arranged on the brush handle can timely acquire a bend index of the brush handle, so that a target measured pressure value of the electric toothbrush can be determined through the bend index of the brush handle, namely, a force applied to the teeth by the user through the electric toothbrush.

As an alternative embodiment, the target reference pressure value of the electric toothbrush may be obtained in various ways, for example, an initial measured pressure value of the electric toothbrush and an initial reference pressure value of the electric toothbrush may be determined, and a second difference value between the initial measured pressure value and the initial reference pressure value may be determined; and determining a target reference pressure value of the electric toothbrush according to the second difference value. The initial measured pressure value of the electric toothbrush is a pressure value determined when the electric toothbrush is just powered on and does not perform any operation, and the initial reference pressure value of the electric toothbrush is a pressure value stored in the electric toothbrush. Because the target reference pressure value is determined according to the second difference value, the influence of errors of the initial measured pressure value can be avoided, and the accurate target reference pressure value is further determined.

As an alternative embodiment, the target reference pressure value of the electric toothbrush may be determined according to the second difference in various ways, for example, the initial measured pressure value may be determined as the target reference pressure value in the case that the second difference is less than or equal to the first threshold; and/or determining the initial reference pressure value as the target reference pressure value under the condition that the second difference value is larger than the first threshold value. And under the condition that the second difference value is smaller than or equal to the first threshold value, namely the difference between the initial measured pressure value and the initial reference pressure value is not large, the initial measured pressure value is proved to be correct, and under the condition, the accuracy of the target reference pressure value can be ensured by determining the initial measured pressure value as the target reference pressure value. Under the condition that the second difference value is larger than the first threshold value, namely the difference between the initial measured pressure value and the initial reference pressure value is large, errors may occur in the initial measured pressure value, and under the condition, the initial reference pressure value is determined to be the target reference pressure value, so that the influence of the errors of the initial measured pressure value can be effectively avoided, and the accuracy of the target reference pressure value is ensured.

As an alternative embodiment, a first difference value of the target measured pressure value and the target reference pressure value is determined; and determining a target vibration mode of the electric toothbrush corresponding to the first difference from a target comparison table, wherein the target comparison table stores a corresponding relation between the difference interval and the vibration mode. The target vibration mode is determined through the target comparison table, and the accuracy of the determined target vibration mode of the electric toothbrush can be effectively guaranteed.

As an alternative embodiment, when the target vibration pattern of the electric toothbrush corresponding to the first difference is determined from the target look-up table, the following may be performed: and under the condition that the first difference is within the preset difference interval, determining the target vibration mode of the electric toothbrush corresponding to the first difference as the constant cleaning mode from the target comparison table. For example, when the user is brushing teeth with the electric toothbrush normally and the pressure applied to the electric toothbrush is moderate, the target vibration mode of the electric toothbrush is the constant cleaning mode, and the power strength of the electric toothbrush motor in the constant cleaning force constant cleaning mode changes along with the pressure value applied to the electric toothbrush by the user, so that the working frequency and the duty ratio of the motor in the electric toothbrush can be adaptively adjusted, the force application of the user is adapted, and the technical effect that the vibration mode is the single cleaning force mode is achieved.

As an alternative embodiment, a target power level of a target motor in the electric toothbrush is determined according to a target vibration pattern; and determining a target working frequency and a target duty ratio of a target motor in the electric toothbrush according to the target power strength so as to adjust the working frequency and the duty ratio of the target motor to the target working frequency and the target duty ratio. Because the target power strength is determined according to the target vibration mode, and the target working frequency and the target duty ratio of the target motor in the electric toothbrush are determined, the target working frequency and the target duty ratio are determined accurately by considering the actual use condition of the user.

As an alternative embodiment, in the case that the target power strength includes a target rotation speed and a target swing, when the target operating frequency and the target duty ratio of the target motor in the electric toothbrush are determined according to the target power strength, the target operating frequency of the target motor in the electric toothbrush may be determined according to the target rotation speed, and the target duty ratio of the target motor in the electric toothbrush may be determined according to the target swing. Under the condition that the target power strength can be embodied by the target rotating speed and the target swing amplitude, the target working frequency is determined according to the target rotating speed, the target duty ratio is determined according to the target swing amplitude, and the target working frequency and the target duty ratio can be determined more accurately.

As an alternative embodiment, a method of determining a target operating frequency and a target duty cycle for a target motor in an electric toothbrush based on a target power level comprises: in the case that the target vibration mode is the constant cleaning mode, a power characteristic curve of the target motor is obtained, and the method for determining the power characteristic curve is to determine an electric toothbrush parameter of the electric toothbrush, and determine a corresponding power characteristic curve according to the electric toothbrush parameter, wherein the electric toothbrush parameter can be a toothbrush model, a battery parameter, a motor parameter and the like, the power characteristic curve represents a corresponding relation between a measured pressure value and a motor power strength, and the target motor is a motor for controlling the vibration of the toothbrush in the electric toothbrush. And determining the target working frequency when the rotating speed of the target motor reaches the target rotating speed and determining the target duty ratio when the swing amplitude of the target motor reaches the target swing amplitude according to the power characteristic curve and the target measured pressure value, thereby achieving the corresponding vibration effect. For example, the corresponding power characteristic curve can be determined according to different motor types of the electric toothbrush, so that the determined power characteristic curve is targeted, and the electric toothbrush can be suitable for electric toothbrushes of different models and different parameters.

It should be noted that the target vibration modes of the electric toothbrush are mainly classified into three types: a splash protection mode, a constant cleaning mode, and an over-pressure protection mode.

1) The anti-splash mode can be set when the first difference is lower, because the lower first difference indicates that the difference between the target measured pressure value and the target reference pressure value of the electric toothbrush is smaller, and the pressure is smaller, which is mainly seen in the situation that the user just opens the electric toothbrush and does not use the electric toothbrush to brush the teeth. The vibration of the electric toothbrush in the splash-proof mode is very weak in order to prevent toothpaste on the electric toothbrush from being splashed out by the vibration of the electric toothbrush.

2) The first difference value may be set to a constant cleaning force mode when the first difference value is within a predetermined range, i.e., when the difference value between the target measured pressure value and the target reference pressure value of the electric toothbrush is within the predetermined range, it indicates that the pressure is being applied, or the like, which is mainly found in a case where the user is brushing his/her teeth using the electric toothbrush normally. Because the power intensity of the motor of the electric toothbrush changes along with the pressure value applied to the electric toothbrush by a user, constant cleaning force is needed, and therefore the working frequency and the duty ratio of the motor in the electric toothbrush can be adaptively adjusted to adapt to the force application of the user, and the effect of constant cleaning force is achieved.

3) The overpressure protection mode can be set when the first difference value is higher, that is, when the difference value between the target measured pressure value and the target reference pressure value of the electric toothbrush is higher, the pressure is higher, and it is mainly seen that a user applies a very large force to the electric toothbrush during using the electric toothbrush, and the user may damage teeth by brushing teeth with the force. The vibration of the power toothbrush in the over-voltage protection mode is stopped or reduced in order to prevent the vibration of the power toothbrush from damaging the teeth of the user.

It should be noted that, since the first difference between the target measured pressure value and the target reference pressure value is determined in the above steps, the solution described in the present application may also be expanded to reduce the target power strength of the target motor by a preset percentage according to the size of the first difference, that is, the effect of reducing the motor rotation speed by the preset percentage may be achieved, and different interval values correspond to different reductions, for example, a reduction of 50% in a certain interval, a reduction of 90% in a certain interval, and the like. Without limitation, the adaptive setting may be performed according to actual applications and scenes.

As an alternative embodiment, determining a target frequency at which the target motor reaches the target rotation speed and determining a target duty cycle at which the target motor reaches the target swing according to the power characteristic curve and the target measured pressure value includes: determining the current power strength corresponding to the target measured pressure value according to the power characteristic curve and the target measured pressure value; according to the current power strength and the target power strength, the target frequency of the target motor reaching the target rotating speed is determined, the target duty ratio of the target motor reaching the target swing amplitude is determined, and the difference between the current power strength and the target power strength can be known, so that the target working frequency and the target duty ratio can be determined more accurately, and the target effect is achieved in time.

As an alternative embodiment, when the above steps are performed, a predetermined time interval may be determined, so that the handle bending index of the electric toothbrush is obtained according to the predetermined time interval, that is, the effect of periodically obtaining the pressure value and adjusting the vibration mode can be achieved. For example, the preset time interval can be determined as 1S, that is, the handle bending index of the electric toothbrush is obtained every 1S, so that the vibration mode of the electric toothbrush can be adjusted in time, and the good use experience of a user is guaranteed.

Based on the above embodiments and alternative embodiments, an alternative implementation is provided, which is described in detail below.

In an alternative embodiment of the present invention, a management method for accurately and timely adjusting the vibration mode of an electric toothbrush is provided, in which the vibration mode of an electric toothbrush that has not been used immediately after leaving a factory is classified into three types: a splash protection mode, a constant cleaning mode, and an over-pressure protection mode. In the constant cleaning mode, a power characteristic curve corresponding to the target vibration mode is set, and in different target measurement pressure values, different motor power strengths are set, and the motor power strengths include the conditions of the motor rotation speed and the swing amplitude as an example, so that the method provided by the optional embodiment of the invention is explained.

Fig. 2 is a flow chart of a method provided by an alternative embodiment of the present invention, and as shown in fig. 2, the following describes the alternative embodiment of the present invention:

s1, determining an initial measurement pressure value of the electric toothbrush and an initial reference pressure value of the electric toothbrush;

s2, determining the difference value between the initial measured pressure value and the initial reference pressure value;

s3, determining a target reference pressure value of the electric toothbrush according to the difference value;

s3.1, determining an initial measured pressure value as a target reference pressure value under the condition that the difference value is less than or equal to a first threshold value;

s3.2, determining the initial reference pressure value as a target reference pressure value under the condition that the difference value is larger than the first threshold value;

s4, obtaining a brush handle bending index, and determining a target measurement pressure value of the electric toothbrush based on the brush handle bending index;

s5, determining a difference value between the target measured pressure value and the target reference pressure value;

s6, determining a target vibration mode of the electric toothbrush corresponding to the difference from a target comparison table, wherein the target comparison table stores the corresponding relation between the difference interval and the vibration mode;

s7, determining the target power strength of a target motor in the electric toothbrush according to the target vibration mode;

s8, determining a target working frequency and a target duty ratio of a target motor in the electric toothbrush according to the target power strength so as to adjust the working frequency and the duty ratio of the target motor to the target working frequency and the target duty ratio;

and S9, acquiring a handle bending index at preset time intervals so as to determine a target measured pressure value of the electric toothbrush.

It should be noted that, in the step of determining the target vibration mode in S6,

1) In the case that the determined vibration mode is the splash-proof mode, the vibration of the electric toothbrush can be directly set to be very weak, so as to prevent toothpaste on the electric toothbrush from being splashed out by the vibration of the electric toothbrush.

2) And under the condition that the determined vibration mode is the constant cleaning mode, determining a power characteristic curve of the constant cleaning mode, and determining the power strength of the target motor from the power characteristic curve according to the difference value between the target measured pressure value and the target reference pressure value so as to enable the working frequency and the duty ratio of the target motor to reach the target working frequency and the target duty ratio.

In this case, since the motor type of the electric toothbrush differs, the power intensity of the motor of the electric toothbrush and the target measured pressure value have different power characteristic curves depending on the characteristics of the motor itself during the use of the electric toothbrush. By way of example, fig. 3 is a relationship curve between the power strength of one type of motor of the electric toothbrush and a target measured pressure value, fig. 3 shows that the power strength of the motor gradually decreases with the increase of the target measured pressure value, fig. 4 shows a relationship curve between the rotating speed of another type of motor of the electric toothbrush and the target measured pressure value, fig. 4 shows that the power strength of the motor first increases and then decreases with the increase of the target measured pressure value, and as shown in fig. 3 and fig. 4, a power characteristic curve adapted to the electric toothbrush can be obtained, so that the effect of timely and accurately adjusting the rotating speed of the motor of the electric toothbrush can be achieved.

In the embodiment shown in fig. 3, the power is stable in the case where the brush head is not subjected to a force, i.e., a pressure of 0. As the force applied to the brush head is gradually increased, the power intensity of the target motor is reduced.

For example, in the constant cleaning mode, as the force applied to the brush head changes, if the target measured pressure increases, the corresponding duty ratio needs to be increased to control the target motor to reach the target swing amplitude, and the operating frequency needs to be increased to control the target motor to reach the target rotating speed, so as to enhance the power, so that the power of the target motor is kept constant, and thus a stable cleaning effect is achieved.

In the embodiment shown in fig. 4, the power is stabilized without stressing the brush head. Along with the gradual increase of the force applied to the brush head, the power is gradually weakened after being gradually enhanced; when the force of the brush head reaches A value, the power is not increased any more, but is gradually reduced along with the gradual increase of the force of the brush head.

For example, in the constant cleaning mode,

a. when the target measured pressure is between the first preset value and the second preset value (equivalent to the value a in the above), along with the change of the stress condition of the brush head, if the target measured pressure is increased, the corresponding duty ratio needs to be reduced to control the target motor to reach the target swing amplitude, the working frequency needs to be reduced to control the target motor to reach the target rotating speed, the power is weakened, and the power is kept constant, so that the stable cleaning effect is achieved.

b. When the target measured pressure is between the second preset value and the third preset value, along with the change of the stress condition of the brush head, if the target measured pressure is increased, the corresponding duty ratio needs to be increased to control the target motor to reach the target swing amplitude, the working frequency is increased to control the target motor rotating speed to reach the target rotating speed, the power is enhanced, and the power is kept constant, so that the stable cleaning effect is achieved.

3) In the case where the determined vibration mode is the over-voltage protection mode, it may be directly set that the vibration of the electric toothbrush is stopped or reduced in order to prevent the vibration of the electric toothbrush from damaging the teeth of the user.

Through the above alternative embodiment, at least the following advantages can be achieved:

(1) The vibration mode of the electric toothbrush can be adjusted in time by determining the target measured pressure value at preset time intervals;

(2) The initial reference pressure value is determined once when the electric toothbrush is electrified every time, so that the influence of deformation caused by long service time of the electric toothbrush can be avoided;

(3) And determining the vibration mode of the electric toothbrush according to the first difference and the target comparison table, so that the vibration mode of the toothbrush can be accurately determined.
