Embodiments of the present invention

In the following description, for the purpose of illustration rather than limitation, specific details such as a specific system structure and technology are set forth in order to provide a thorough understanding of the embodiments of the present application. However, it will be apparent to those skilled in the art that the present application may be practiced in other embodiments without these specific details. In other instances, detailed descriptions of well-known systems, devices, circuits, and methods are omitted so as not to obscure the description of the present application with unnecessary detail.

It is to be understood that, when used in this specification and the appended claims, the term "comprising" indicates the presence of the described feature, integer, step, operation, element and/or component, but does not exclude one or more other features , whole, step, operation, element, component and/or the presence or addition of a collection thereof.

During the use of the existing electric toothbrush, the vibration intensity of the brush head is generally fixed, and the fixed vibration intensity may cause the problem of unstable cleaning force or damage to the gums. To this end, the present application provides a control method for an electric toothbrush, comprising: obtaining a pressure value on the brush head of the electric toothbrush, and if the pressure value is less than a preset overpressure value, according to a first preset value of the pressure value and the vibration intensity The relationship adjusts the vibration intensity of the brush head, and the first preset relationship is a positive correlation relationship, that is, the vibration intensity gradually increases with the increase of pressure, so that the cleaning force can be kept constant within a certain pressure range to achieve effective cleaning of teeth. If the pressure value is greater than or equal to the preset overpressure value, the vibration intensity of the brush head is adjusted according to the second preset relationship between the pressure value and the vibration intensity. The second preset relationship is a negative correlation, that is, it gradually decreases as the pressure increases. Low vibration intensity, thus protecting the gums from excessive pressure.

The following is an exemplary description of the control method of the electric toothbrush provided by the embodiments of the present application. Referring to FIG. 1, a control method for an electric toothbrush provided by an embodiment of the present application includes:

S101: Obtain the pressure value of the brush head of the electric toothbrush.

Specifically, the handle of the electric toothbrush is provided with a pressure sensor, and the pressure detected by the pressure sensor is the pressure value received by the brush head.

In a possible implementation, the handle of the electric toothbrush is provided with a motor, and the pressure sensor is provided on the bracket at the front end of the motor. When the brush head is under pressure, the pressure is transmitted to the motor shaft through the brush head, and then transmitted to the motor shaft through the motor shaft. The bracket at the front end of the motor causes the pressure sensor to deform and detect the pressure value on the brush head.

S102: If the pressure value is less than a preset overpressure value, adjust the vibration intensity of the brush head according to a first preset relationship between the pressure value and the vibration intensity, where the first preset relationship is a positive correlation.

The preset overvoltage value is determined according to pre-detected experimental data, and the first preset relationship may be a linear function. The brush head is connected to the motor, and the vibration intensity of the brush head can be adjusted by controlling the frequency or duty ratio of the motor during operation.

There is a positive correlation between the pressure value and the vibration intensity, that is, as the pressure value increases, the vibration intensity gradually increases. Since when the pressure value is less than the preset overpressure value, with the increase of the pressure value, if the vibration intensity remains unchanged, the cleaning force will show a downward trend. Therefore, when the pressure value increases, it will increase according to the first preset relationship. The vibration intensity can improve the cleaning force, so as to keep the cleaning force constant in the process of changing the pressure value, so as to achieve effective cleaning of the teeth.

In a possible implementation manner, the maximum threshold value of the vibration intensity is preset, and if the pressure value is less than the preset overpressure value, as the pressure value increases, the vibration intensity is gradually increased according to the first preset relationship, and the When the vibration intensity increases to the maximum threshold value, with the increase of the pressure value, the vibration intensity remains unchanged, so that the motor of the electric toothbrush can be protected and the service life of the motor can be prolonged.

It should be noted that, in other feasible implementation manners, when the pressure value is less than the preset overpressure value, as the pressure value increases, the pressure value and the vibration intensity can always maintain a positive correlation.

In a possible implementation manner, in the process of changing the vibration intensity, the user can be prompted by an indicator light provided on the electric toothbrush. For example, if the vibration intensity is within the first preset range, the green indicator light on the electric toothbrush will light up. , if the vibration intensity is within the second preset range, the red indicator light on the electric toothbrush will light up to remind the user of the current vibration intensity of the brush head, so that the user can adjust the brushing intensity in time.

S103: If the pressure value is greater than or equal to the preset overpressure value, adjust the vibration intensity of the brush head according to a second preset relationship between the pressure value and the vibration intensity, and the second preset relationship is a negative correlation .

Wherein, the second preset relationship may be a linear function. There is a negative correlation between the pressure value and the vibration intensity, that is, as the pressure value increases, the vibration intensity gradually decreases. Because when the pressure value is greater than or equal to the preset overpressure value, with the increase of the pressure value, if the vibration intensity remains unchanged, the brush head will cause certain damage to the gums. Therefore, with the increase of the pressure value, according to the The second preset relationship reduces the vibration intensity and can effectively protect the gums.

In a possible implementation manner, the minimum threshold value of the vibration intensity is preset, and if the pressure value is greater than or equal to the preset overpressure value, as the pressure value increases, the vibration intensity is gradually reduced according to the second preset relationship, And when the vibration intensity is reduced to the minimum threshold value, with the increase of the pressure value, the vibration intensity remains unchanged, so that the teeth can be effectively cleaned.

It should be noted that, in other feasible implementation manners, when the pressure value is greater than or equal to the preset overpressure value, as the pressure value increases, the pressure value and the vibration intensity can always maintain a negative correlation.

In the above embodiment, if the pressure value is less than the preset overpressure value, the vibration intensity of the brush head is adjusted according to the first preset relationship between the pressure value and the vibration intensity, that is, the vibration intensity is gradually increased as the pressure increases, so that the The cleaning force is kept constant within a certain pressure range to achieve effective cleaning of the teeth. If the pressure value is greater than or equal to the preset overpressure value, the vibration intensity of the brush head is adjusted according to the second preset relationship between the pressure value and the vibration intensity, that is, the vibration intensity is gradually reduced as the pressure increases, so that the vibration intensity can be reduced when the pressure is too large. protect the gums.

In a possible implementation manner, a reference pressure value is preset, and the reference pressure value is the pressure value on the brush head when the electric toothbrush is in an invalid brushing state (eg, no load or wrong brushing posture). The reference pressure value can be fixed or determined according to the pressure value detected by the pressure sensor. Obtain the pressure value detected by the pressure sensor in real time, and determine the relationship between the pressure value and the preset overpressure value when the pressure value is greater than the reference pressure value. If the pressure value is greater than the reference pressure value and the pressure value is less than the preset overpressure value, the vibration intensity of the brush head is adjusted according to the first preset relationship between the pressure value and the vibration intensity. If the pressure value is less than the reference pressure value, the brush head stops vibrating, or the brush head keeps the preset vibration intensity unchanged, so that the energy consumption of the electric toothbrush can be saved when the electric toothbrush is in an invalid brushing state.

In a possible implementation manner, the relationship between the pressure value and the vibration intensity is shown in Figure 2, the reference pressure value is 50g, and when the pressure value is less than 50g, the vibration intensity remains unchanged. When 50g<pressure value<300g, the pressure value has a positive correlation with the vibration intensity. With the increase of the pressure value, the vibration intensity gradually increases. When the pressure value is equal to 300g, the vibration intensity reaches 100% of the maximum threshold value, and as the pressure value increases, the vibration intensity remains unchanged. The overpressure value is 400g. When 400g<pressure value<500g, the pressure value and the vibration intensity are negatively correlated. As the pressure value increases, the vibration intensity gradually decreases. When the pressure value is equal to 500g, the vibration intensity reaches the minimum threshold of 10%, and as the pressure value increases, the vibration intensity remains unchanged.

In a possible implementation, the pressure value of the brush head when the electric toothbrush is no-load is taken as the reference pressure value, and relative to the preset reference pressure value, the pressure on the brush head when the electric toothbrush is no-load is used as the reference pressure value. The value is used as the reference pressure value, which can make the reference pressure value match the motor and improve the accuracy of the electric toothbrush control. In a possible implementation, whether the user is using the electric toothbrush can be detected through a contact sensor or an infrared sensor on the electric toothbrush. If it is detected that the user is not using the electric toothbrush, it means that the electric toothbrush is empty. In another possible implementation manner, the pressure value detected by the pressure sensor is acquired in real time, and if the pressure value received by the brush head is less than the set pressure value, it is determined that the electric toothbrush is unloaded. Whether the electric toothbrush is unloaded is determined by the pressure value received by the brush head, which improves the accuracy of the determined state of the electric toothbrush.

In a possible implementation manner, the reference pressure value can be changed in real time according to the pressure value detected by the pressure sensor. Specifically, if the pressure value detected by the pressure sensor is greater than the reference pressure value, the reference pressure value remains unchanged. If the pressure value detected by the pressure sensor is smaller than the reference pressure value, it means that the electric toothbrush has no load, and the reference pressure value is updated to pressure The pressure value detected by the sensor can obtain a more accurate pressure value of the electric toothbrush when the electric toothbrush is not loaded, thereby improving the control accuracy of the electric toothbrush.

In a possible implementation manner, the control flow of the electric toothbrush is shown in FIG. 3 . After the electric toothbrush is turned on, the pressure sensor is activated, and if it is determined that the electric toothbrush is in an no-load state according to the pressure value detected by the pressure sensor, the brush head keeps the preset vibration intensity unchanged. If it is determined that the electric toothbrush is in the no-load state, the pressure value detected by the pressure sensor is obtained, and the pressure value is used as the reference pressure value. Obtain the current pressure value detected by the pressure sensor in real time, and determine whether the current pressure value is greater than the reference pressure value. If the current pressure value is less than the reference pressure value, update the reference pressure value to the current pressure value, that is, substitute the current pressure value into the reference pressure value as a new reference pressure value and compare it with the next detected pressure value. If the current pressure value is greater than the reference pressure value, determine whether the current pressure value is greater than the preset overpressure value, if the current pressure value is less than or equal to the preset overpressure value, adjust the vibration intensity according to the first preset relationship, and when the vibration intensity reaches the maximum At the threshold, as the pressure value increases, the vibration intensity remains unchanged. If the current pressure value is greater than the preset overpressure value, the vibration intensity is adjusted according to the second preset relationship, and when the vibration intensity reaches the minimum threshold value, the vibration intensity remains unchanged as the pressure value increases. After the adjustment of the vibration intensity is completed, the next detected pressure value is compared with the reference pressure value.

In a possible implementation manner, during the use of the electric toothbrush, the position of the brush head in the oral cavity is detected, and the corresponding first preset relationship and the second preset relationship are determined according to the position of the brush head in the oral cavity, Therefore, the vibration intensity of the brush head can be adjusted according to the brushing part, and the teeth can be cleaned better. The inclination angle of the electric toothbrush can be determined by the accelerometer or gyroscope installed on the electric toothbrush, and the position of the brush head in the oral cavity can be determined according to the inclination angle of the electric toothbrush and the attitude fusion algorithm.

In another possible implementation, the pressure sensor is composed of a plurality of pressure detection units, and the plurality of pressure detection units are evenly distributed on the brush head, and can detect the pressure value received by each position of the brush head, according to each position of the brush head. The pressure value received can determine the pressure distribution on the surface of the brush head, and the inclination angle of the brush head can be determined according to the pressure distribution. Location.

In a possible implementation, after detecting the position of the brush head in the oral cavity, start the timer, and if it is determined according to the timing result that the brush head is in the same position for more than a preset time period, reduce the vibration intensity of the brush head to prevent the Gum discomfort caused by the user brushing the same part of the teeth for a long time.

In a possible implementation manner, the electric toothbrush includes multiple cleaning modes, such as normal cleaning, deep cleaning, etc. According to the cleaning mode selected by the user, the corresponding first preset relationship and the second preset relationship are determined, so that the The vibration intensity of the brush head is adapted to the cleaning mode to meet the different brushing needs of users.

In a possible implementation manner, in order to save the space occupied by the motor and the pressure sensor in the electric toothbrush, the pressure sensor is located at the front end of the motor. In this design method, the vibration of the motor will affect the accuracy of the pressure value measured by the pressure sensor. In order to improve the accuracy of the measured pressure value, the measured pressure value can be filtered, and the filtered pressure The value is used as the pressure value on the brush head, thereby improving the accuracy of the measured pressure value.
