[0017] In order to further explain the technical means and effects adopted by the present invention to achieve the predetermined invention purpose, the following is a detailed description of the specific implementation, structure, features and effects of an electric toothbrush intelligent control method and system proposed by the present invention in combination with the accompanying drawings and preferred embodiments. In the following description, different "one embodiment" or "another embodiment" does not necessarily refer to the same embodiment. In addition, specific features, structures or characteristics in one or more embodiments may be combined in any suitable form.

[0018] Unless defined otherwise, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention belongs.

[0019] The specific scheme of the intelligent control method and system of an electric toothbrush provided by the present invention is described in detail below with reference to the accompanying drawings.

[0020] See also Figure 1 , which shows a flowchart of a method for intelligently controlling an electric toothbrush provided by an embodiment of the present invention, the method comprising the following steps: Step S001: Obtain the bristle pressure data sequence of different tooth areas of the user, as well as the theoretical pressure range and normal vibration frequency value of the electric toothbrush.

[0021] Specifically, it is necessary to first collect the bristle pressure data sequence of different tooth areas of the user, as well as the theoretical pressure range and conventional vibration frequency value of the electric toothbrush. The specific process is as follows: The user's teeth are divided into four dental areas: upper left, upper right, lower left and lower right. A miniature pressure sensor is installed on the brush head of the electric toothbrush to record the user's brushing of each dental area at a sampling moment every 1 second, and obtain the bristle pressure data of each dental area at each sampling moment; the sequence composed of the bristle pressure data of each dental area at all moments is used as the bristle pressure data sequence of each dental area.

[0022] It should be noted that since normal and healthy gums can tolerate a pressure range of approximately 100-200, this pressure range can ensure that the gums are not damaged and avoid gum recession caused by excessive friction. The hardness of the tooth surface is relatively high, but excessive pressure may still cause damage to the enamel, especially in irregular areas of the tooth surface. Usually, the enamel will not be damaged under a pressure below 300.

[0023] Preferably, two theoretical pressure parameters are preset , wherein this embodiment is based on This example is described as an example, and this embodiment is not specifically limited. Depends on the specific implementation situation; As the theoretical pressure range of an electric toothbrush; The normal vibration frequency value of the electric toothbrush can be obtained by referring to the product manual of the electric toothbrush.

[0024] So far, the bristle pressure data sequence of different tooth areas of the user, as well as the theoretical pressure range and conventional vibration frequency value of the electric toothbrush are obtained through the above method.

[0025] Step S002: According to the theoretical pressure range of the electric toothbrush, the bristle pressure data sequence of each tooth area is divided into multiple pressure data segments; according to the difference between the bristle pressure data in each pressure data segment and the theoretical pressure range of the electric toothbrush, the pressure behavior abnormal value of each tooth area is obtained; the abnormal threshold range is obtained; according to the difference between the pressure behavior abnormal value of the tooth area and the abnormal threshold range, the abnormal difference value of each tooth area is obtained; according to the difference between the abnormal difference values ​​of adjacent tooth areas, the necessity of parameter adjustment of each tooth area is obtained; according to the necessity of parameter adjustment of the tooth area and the conventional vibration frequency value of the electric toothbrush, the adjusted vibration frequency value of each tooth area is obtained.

[0026] It should be noted that electric toothbrushes use pressure sensors to sense the pressure applied by the bristles. If the pressure is too high, it may damage the gums and enamel; if the pressure is too low, it may not effectively clean the tooth surface; according to the theoretical pressure range of the electric toothbrush, dividing the pressure data segments can help determine the ideal pressure range required for each tooth area, thereby avoiding excessive or insufficient brushing force.

[0027] Preferably, in some implementations of the embodiments of the present invention, the specific method of dividing the bristle pressure data sequence of each tooth area into multiple pressure data segments according to the theoretical pressure interval of the electric toothbrush is: A two-dimensional rectangular coordinate system is constructed with the sampling time as the horizontal coordinate and the bristle pressure data as the vertical coordinate; for a bristle pressure data sequence of any tooth area, the bristle pressure data sequence of the tooth area is input into the two-dimensional rectangular coordinate system, and the curve is fitted using the least squares method to obtain a fitting curve of the bristle pressure data of the tooth area; in the two-dimensional rectangular coordinate system, the intersection points between the fitting curve of the bristle pressure data of the tooth area and the two boundaries of the theoretical pressure range of the electric toothbrush are recorded as dividing intersection points; according to the dividing intersection points, the bristle pressure data sequence of the tooth area is divided into a number of pressure data segments.

[0028] It should be noted that since the toothbrush head moves up and down during brushing to clean the tooth area and ensure brushing coverage, the pressure parameter is not constant, but moves periodically. Therefore, the pressure value during normal brushing also shows approximately periodic changes. Therefore, the pressure changes in time series are used to determine whether they are in the theoretical pressure range. If so, it means that the pressure parameters for brushing are normal. On the contrary, if the difference between the pressure value during brushing and the theoretical pressure range is large, it means that the user's brushing behavior is abnormal, thereby obtaining abnormal pressure behavior values ​​in the tooth area.

[0029] Preferably, in some implementations of the embodiments of the present invention, according to the difference between the bristle pressure data in each pressure data segment and the theoretical pressure interval of the electric toothbrush, the specific method for obtaining the abnormal behavior value of each pressure data segment is: For any pressure data segment of the bristle pressure data sequence of the tooth area, the mean value of the bristle pressure data at all sampling moments in the pressure data segment is recorded as the first mean value of the pressure data segment; the absolute value of the difference between the first mean value of the pressure data segment and the left boundary value of the theoretical pressure interval of the electric toothbrush is recorded as the first difference; the absolute value of the difference between the first mean value of the pressure data segment and the right boundary value of the theoretical pressure interval of the electric toothbrush is recorded as the second difference; the minimum value between the first difference and the second difference is selected as the abnormal factor of the pressure data segment; Preset a constant , wherein this embodiment is based on This example is described as an example, and this embodiment is not specifically limited. Depends on the specific implementation situation; If the bristle pressure data at all sampling moments in the pressure data segment are not within the theoretical pressure interval of the electric toothbrush, the product of the abnormal factor of the pressure data segment and the number of all sampling moments in the pressure data segment is used as the abnormal behavior value of the pressure data segment; if the bristle pressure data at all sampling moments in the pressure data segment are within the theoretical pressure interval of the electric toothbrush, As the abnormal behavior value of the pressure data segment.

[0030] It should be noted that if the bristle pressure data at all sampling moments in the pressure data segment are not within the theoretical pressure range of the electric toothbrush, then the pressure data segment is an abnormal data segment. Therefore, the longer the duration of the pressure data segment, the larger the corresponding abnormal behavior value; although there is a difference between the theoretical pressure value range, if the difference is small, the corresponding abnormal behavior value is smaller.

[0031] Preferably, in some implementations of the embodiments of the present invention, the specific method for obtaining the pressure behavior abnormal value of each tooth area according to the abnormal behavior value of the pressure data segment is: For any tooth region, a normalized value of the average of the abnormal behavior values ​​of all pressure data segments of the bristle pressure data sequence of the tooth region is used as the pressure behavior abnormal value of the tooth region; The specific formula is: In the formula, Indicates abnormal values ​​of pressure behavior in the tooth area; The number of all pressure data segments representing the bristle pressure data sequence for the tooth region; The first sequence of bristle pressure data representing the tooth area Abnormal behavior value of each pressure data segment; represents the linear normalization function.

[0032] It should be noted that if the abnormal value of pressure behavior in the dental area is greater than the abnormal threshold interval, it means that there is a significant abnormality in the dental cleaning of this dental area, and the user has applied a larger pressure value. At this time, the user should reduce the pressure applied to the electric toothbrush; if the abnormal value of pressure behavior in the dental area is in the abnormal threshold interval, it means that the cleaning of this dental area is normal, and the user has a good control of the strength; if the abnormal value of pressure behavior in the dental area is less than the abnormal threshold interval, it means that there is a significant abnormality in the dental cleaning of this dental area, and the user has applied a smaller pressure value. At this time, the user should increase the pressure applied to the electric toothbrush.

[0033] Preferably, in some implementations of the embodiments of the present invention, the specific method of presetting an abnormal threshold interval is: Preset two abnormal threshold parameters , wherein this embodiment is based on This example is described as an example, and this embodiment is not specifically limited. Depends on the specific implementation situation; as the abnormal threshold interval.

[0034] It should be noted that if the abnormal value of the pressure behavior in the tooth area is within the abnormal threshold range, it means that the vibration frequency of the electric toothbrush required by the user is incorrect; the greater the possibility of adjusting the vibration frequency parameters of the electric toothbrush, and the size of the adjustment needs to be based on the difference between the abnormal value of the pressure behavior in the tooth area and the abnormal threshold range, so as to obtain the abnormal difference value of each tooth area.

[0035] Preferably, in some implementations of the embodiments of the present invention, according to the difference between the pressure behavior abnormal value of the tooth area and the abnormal threshold interval, the specific method for obtaining the abnormal difference value of each tooth area is: For any tooth area, if the abnormal pressure behavior value of the tooth area is between the abnormal threshold interval, the absolute value of the difference between the abnormal pressure behavior value of the tooth area and the left boundary value of the abnormal threshold interval is recorded as the third difference; the absolute value of the difference between the abnormal pressure behavior value of the tooth area and the right boundary value of the abnormal threshold interval is recorded as the fourth difference; the minimum value between the third difference and the fourth difference is selected as the abnormal difference value of the tooth area; if the abnormal pressure behavior value of the tooth area is not between the abnormal threshold interval, as the abnormal difference value of the tooth area.

[0036] It should be noted that in actual practice, there are only a few brushing modes for electric toothbrushes. When facing different groups of people, factors such as age and gender will affect the pressure that users apply to their teeth through electric toothbrushes. A single abnormal threshold interval judgment will lead to incorrect feedback on the user's brushing condition, that is, the obtained theoretical pressure range is not representative for individual users. Therefore, it is also necessary to obtain the necessity of parameter adjustment for each tooth area based on the difference between the abnormal difference values ​​of adjacent tooth areas of the user, and then adjust the vibration frequency parameters of the user's electric toothbrush.

[0037] Preferably, in some implementations of the embodiments of the present invention, the specific method for obtaining the necessity of adjusting the parameters of each tooth region according to the difference between the abnormal difference values ​​of adjacent tooth regions is: The first The abnormal difference value of the tooth area is The absolute value of the difference between the abnormal difference values ​​of the tooth areas is recorded as the first absolute value of the difference; The ratio of the abnormal difference value of the first tooth area to the absolute value of the first difference is taken as the Necessity of parameter adjustment for each tooth area; The specific formula is: In the formula, Indicates Necessity of parameter adjustment for each tooth area; Indicates Abnormal difference values ​​for each tooth region; Indicates Abnormal difference values ​​for each tooth region; Represents the preset hyperparameters. This implementation presets , used to prevent the denominator from being 0; Indicates taking the absolute value.

[0038] It should be noted that It indicates the difference between the abnormal difference values ​​of the user's adjacent tooth areas. If the difference is larger, it means that the brushing pressure of the user has been significantly improved after self-adjustment, which means that the possibility of the user's brushing error is greater, and the possibility of the vibration parameter error of the electric toothbrush is smaller, and the need for adjustment is smaller.

[0039] Preferably, in some implementations of the embodiments of the present invention, according to the necessity of adjusting the parameters of the tooth area and the conventional vibration frequency value of the electric toothbrush, the specific method for obtaining the adjusted vibration frequency value of each tooth area is: The first The product of the parameter adjustment necessity of the tooth area and the normal vibration frequency value of the electric toothbrush is taken as the Adjustment frequency factor for each tooth area; Jordi The pressure behavior abnormal value of the tooth area is less than the minimum value in the abnormal threshold interval, and the normal vibration frequency value of the electric toothbrush is compared with the first The difference between the adjustment frequency factors of the tooth areas is taken as the The adjusted vibration frequency value of each tooth area; if the The abnormal pressure behavior value of the tooth area is greater than the maximum value in the abnormal threshold interval, and the normal vibration frequency value of the electric toothbrush is compared with the The sum of the adjustment frequency factors of the tooth regions is taken as the Adjusted vibration frequency value for each tooth area.

[0040] It should be noted that if the abnormal value of the pressure behavior in the tooth area is on the left side of the abnormal threshold range, it means that the pressure applied by the user to the teeth is too high. At this time, the vibration frequency of the toothbrush should be reduced to prevent damage to the teeth and gums. At this time, the greater the necessity of adjusting the corresponding parameters, the greater the pressure is, and the vibration frequency should be reduced; if the If the abnormal value of the pressure behavior of each tooth area is on the right side of the abnormal threshold range, it means that the pressure applied by the user to the teeth is too small, and the vibration frequency of the toothbrush should be increased.

[0041] So far, the adjusted vibration frequency value of each tooth area of ​​the user is obtained through the above method.

[0042] Step S003: Intelligently control the electric toothbrush based on the adjusted vibration frequency value.

[0043] Specifically, the user manually inputs the adjusted vibration frequency value of each tooth area through the mobile phone application, and the intelligent control system of the electric toothbrush will dynamically adjust the vibration frequency value, and the electric toothbrush will automatically switch to the appropriate cleaning mode for each tooth area.

[0044] See also Figure 2 , which shows a characteristic relationship flow chart of an electric toothbrush intelligent control method; Through the above steps, an intelligent control of an electric toothbrush is completed.

[0045] The present invention also proposes an intelligent control system for an electric toothbrush, comprising a memory, a processor, and a computer program stored in the memory and executable on the processor, wherein when the processor executes the computer program, steps S001 to S003 of an intelligent control method for an electric toothbrush are implemented.

[0046] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the principles of the present invention should be included in the protection scope of the present invention.
