Fig. 1 is a schematic view of an implementation environment related to a method for managing brushing teeth based on an electric toothbrush according to an embodiment of the present application. Referring to fig. 1, the implementation environment includes: an electric toothbrush 101 and a mobile terminal 102.

Wherein the mobile terminal 102 is an electronic device used by a user. In the embodiment of the present application, a target APP (Application) is installed on the mobile terminal 102, and the mobile terminal 102 manages the electric toothbrush 101 based on the target APP, for example, executes the brushing management method provided in the embodiment of the present application.

In one possible implementation, the mobile terminal 102 is of the type of a smart phone or tablet, etc., as the application is not limited in this regard. Fig. 1 illustrates a mobile terminal 102 as a smartphone.

In another possible implementation, a wireless connection, such as a Bluetooth connection or a wireless network connection, is established between the powered toothbrush 101 and the mobile terminal 102. Wherein, the wireless network connection here means that the electric toothbrush 101 and the mobile terminal 102 are under the same wireless network.

Based on the implementation environment, the embodiment of the application realizes scoring of the tooth brushing actions of the user and outputs the scoring result by acquiring the tooth brushing action data of the user in a plurality of dimensions. By the scheme of scoring the brushing actions in multiple dimensions, the brushing effect of the user can be comprehensively and accurately estimated, the brushing actions of the user are improved, and the normalization of brushing of the user is enhanced. In addition, the mobile terminal 102 may also feedback brushing improvement advice to the user based on the scoring results to assist the user in improving brushing skills and improving brushing effectiveness.

The following description will be made of a brushing management scheme provided by examples of the present application.

Fig. 2 is a flowchart of a method for managing brushing teeth based on an electric toothbrush according to an embodiment of the present application. The subject of the method is a computer device, such as the mobile terminal 102 shown in fig. 1, connected to the electric toothbrush. Referring to fig. 2, the method flow comprises the steps of:

201. The method comprises the steps that computer equipment obtains tooth brushing behavior data of a user; wherein the brushing behavior data includes duration, coverage, uniformity, and overpressure times of the brushing process; the coverage rate is used for measuring whether the tooth brushing angle is comprehensive; uniformity is related to residence time at each brushing angle; the number of overpressure events is related to brushing force.

Wherein, the duration of the brushing process refers to the total duration of actual brushing. And the total actual brushing time is the time that the brush head of the electric toothbrush is in contact with the teeth and the pressure to which the brush head is subjected is greater than a pressure threshold (also referred to as a second pressure threshold). For example, during brushing, the user may not be able to feel or bear little pressure on the brush head of the electric toothbrush because the user is not brushing his or her teeth, and the duration may not be counted.

Coverage is related to brushing angle, which is also referred to as brushing face. Coverage is the determination of whether each face of the tooth is covered from a brushing perspective. The uniformity is calculated based on the length of time the user spends brushing each brushing angle during brushing.

In addition, the overvoltage phenomenon of the electric toothbrush means that the user applies excessive force during brushing, namely, the pressure applied to the brush head is excessive, so that the brush head of the electric toothbrush is excessively bent or twisted, the normal operation of the electric toothbrush is disturbed, and the electric toothbrush can be damaged under more serious conditions.

Illustratively, the computer device has built-in scoring system that scores the user's brushing motion. The scoring system comprises a data receiving module and a scoring module.

In one possible implementation, the computer device obtains the user's brushing behavior data by:

Mode 1, the data receiving module receives the actual total brushing duration (i.e., duration of brushing session), coverage, uniformity, and overpressure number sent by the electric toothbrush.

Mode 2, the data receiving module receives the actual total brushing time, the number of times of overpressure, the number of brushing angles and the stay time at each brushing angle sent by the electric toothbrush. Thereafter, the coverage and uniformity of the user's brushing process is determined by the scoring module based on the number of brushing angles and the length of stay at each brushing angle.

In another possible implementation, the number of overpressure increases by one for each brushing effort during brushing that exceeds the pressure threshold (also referred to as the first pressure threshold).

In addition, the electric toothbrush can record the number of times of overpressure caused by excessive force of a user, acquire the real-time brushing force in the brushing process and send brushing force data to the data receiving module. The number of overpressures is then determined by the scoring module based on brushing force data, which is not limiting in the present application.

In addition, the electric toothbrush is also equipped with a pressure reminding function. If the pressure applied by the user to the brush head during brushing is too great, the user can be reminded to adjust the brushing posture. Illustratively, the pressure alert means herein includes a voice alert and an indicator light alert. For example, different overpressure levels may be indicated by different colored indicator lights. In addition, in addition to the power toothbrush being equipped with a pressure alert function, the computer device may also alert the user of pressure through the installed target APP. Illustratively, the pressure alert mode herein includes at least one of a text alert and a voice alert.

In the embodiment of the application, the electric toothbrush has the following cleaning modes for users to select according to different output power levels. Illustratively, the output power includes both force and speed.

1. Adaptive mode

In an embodiment of the present application, the adaptive mode includes a plurality of cleaning levels. Wherein a cleaning level corresponds to a power output range, and the power output range includes a brushing speed range and a brushing force range.

Illustratively, the above-mentioned cleaning grade fractions are: standard cleaning, medium cleaning and deep cleaning.

For each cleaning level in the adaptive mode, embodiments of the present application support independent power-free adjustment at that cleaning level.

By stepless adjustment is meant that the adjustment is carried out continuously (rather than by jump adjustment), i.e. at any relatively smooth level within a range, i.e. at any point between the minimum value and the maximum value of the range, without a preset gear. Correspondingly, independent power stepless adjustment means that power continuous adjustment can be carried out at will in the power output range corresponding to each cleaning grade.

It should be noted that, the power output range corresponding to each cleaning level may be divided into steps, which is not limited in the present application.

The second point to be described is that after the user selects the target cleaning level, the computer device displays a speed adjustment control and a force adjustment control through the target APP. The speed adjustment control is used for presenting a brushing speed range under the target cleaning grade, and the force adjustment control is used for presenting a brushing force range under the target cleaning grade.

In an embodiment of the application, in response to detecting a first touch operation of the speed adjustment control by a user, the computer device adjusts a brushing speed of the electric toothbrush based on the first touch operation; or in response to detecting a second touch operation of the force adjustment control by the user, the computer device adjusts the brushing force of the electric toothbrush based on the second touch operation.

Illustratively, the speed adjustment control and the intensity adjustment control are in a progress bar style. Accordingly, the first touch operation is a sliding operation on a speed progress bar, and the second touch operation is a sliding operation on a force progress bar.

2. Single power output mode

In the embodiment of the application, the single power output mode means: when the pressure applied to the brush head of the electric toothbrush is within the target pressure range, the electric toothbrush outputs a single value of power.

For example, in a single power output mode, the motor of the electric toothbrush outputs a single value of power when the user applies an internal pressure in the range of 60-250g to the brush head.

In one possible implementation, the single power output mode includes, but is not limited to: a novice mode, an up fire mode, a stain removing mode, a gum protecting mode, a super strong mode and the like. Wherein the several modes mentioned herein correspond to different power values.

In another possible implementation, for a single power output mode, it is possible to switch to independent power stepless regulation in addition to outputting a single value of power. Namely, a power output range is set for each mode, and power continuous adjustment can be carried out at will in the power output range corresponding to each mode.

Wherein, the power output ranges corresponding to different modes are obviously different. Taking a novice mode as an example, the upper limit of the corresponding power output range is not suitable to be set too large, so that a novice user can adapt to the tooth brushing mode of the electric toothbrush.

3. Personality customization mode

The embodiment of the application also supports the user to define the output force and speed of the movement of the electric toothbrush.

Illustratively, the user-adjustable power range is maximized in the personality customization mode. For example, the power output range of the personalized mode is greater than the power output range corresponding to each cleaning level in the adaptive mode.

202. The computer device scores the brushing motion of the user according to the obtained brushing behavior data and outputs a scoring result.

After the user finishes brushing his teeth, the computer device may score the user's brushing motion based on the obtained brushing behavior data and output a scoring result. Illustratively, embodiments of the present application determine whether brushing is finished by the user whether to turn off the electric toothbrush.

In addition, for detailed scoring processes, please refer to the following description.

The foregoing fig. 2 is merely a basic flow of an embodiment of the present application, and the following further describes a scheme provided by the present application based on a specific implementation, and fig. 3 is a flowchart of another method for managing brushing teeth based on an electric toothbrush provided by the embodiment of the present application, taking interaction between the electric toothbrush and a mobile terminal as an example, as shown in fig. 3, where the method flow includes the following steps:

301. After brushing, the electric toothbrush sends the duration of the user's brushing session, the number of overpressures, the number of brushing angles, and the dwell time at each brushing angle to the mobile terminal.

Wherein the brushing angle is also referred to as brushing face. In one possible implementation, the brushing angle includes, but is not limited to, the following: the left outer side surface, the right outer side surface, the left inner side surface, the right inner side surface and the right inner side surface of the teeth, an upper tooth occlusal surface and a lower tooth occlusal surface.

The first point is that the lateral side is also called labial or buccal surface, and the medial side is also called lingual or palate surface.

The second point is that the left outer side surface is divided into a left outer side surface of the upper tooth and a left outer side surface of the lower tooth; the right outer side surface is divided into a right outer side surface of the upper tooth and a right outer side surface of the lower tooth; the front outer side surface is divided into a front outer side surface of the upper tooth and a front outer side surface of the lower tooth; the left inner side surface is divided into a left inner side surface of the upper tooth and a left inner side surface of the lower tooth; the right inner side surface is divided into a right inner side surface of the upper tooth and a right inner side surface of the lower tooth; the right inner side surface is divided into a right inner side surface of the upper tooth and a right inner side surface of the lower tooth.

In one possible implementation, the user may set a target duration of the brushing session (also referred to as a target total brushing duration, abbreviated as a target total duration) by a target App installed on the mobile terminal. Illustratively, the target total duration is set to a range of 2 to 10 minutes, such as 2.5 minutes, because brushing typically occurs for 2 to 3 minutes to effectively remove bacteria and stains from the oral cavity and avoid enamel wear.

The third point is that the above is merely an example of setting the target total time length. The duration of the brushing process will also depend on the individual. For example, a person with good oral health is enough for 2 minutes, while a person with more oral problems needs a suitable extension time. And after the user sets the target total duration, the user can be reminded of the brushing duration accordingly. For example, the electric toothbrush may be alerted by voice after a set target total time period is reached. For another example, after reaching the set target total duration, the mobile terminal carries out text reminding or voice reminding on the user through the target APP.

In another possible implementation, the mobile terminal may also recommend the duration of the brushing session to the user by:

Acquiring oral health data of a user; wherein the oral health data is used for reflecting the oral health condition of the user; thereafter, a duration of a brushing session is recommended to the user based on the user's oral health data.

Illustratively, the embodiment of the present application obtains oral health data of the user by:

Acquiring oral physical examination data, oral visual examination data, oral biochemical examination data and oral function data of the user; wherein, the oral function data is used for reflecting the difficulty level of the user when chewing food.

And then, inputting the oral physical examination data, the oral visual examination data, the oral biochemical examination data and the oral function data of the user into an oral health prediction model, and determining the oral health condition of the user through the oral health prediction model to obtain the oral health data of the user.

In embodiments of the present application, oral physical examinations include, but are not limited to, oral endoscopy, oral X-ray examination, oral CT examination, and the like; oral visual inspection refers to observing the state of the interior of the oral cavity, such as color, morphology, position and size, and whether there are abnormal conditions such as ulcers, redness or induration.

For example, oral physical examination data, oral visual examination data, oral biochemical examination data, oral function data, etc. may be obtained from the user's electronic health record, as the application is not limited in this regard. In addition, the oral health prediction model can be trained as follows:

first, a training sample set for training an oral health prediction model is obtained.

Wherein the training sample set includes oral health data of a plurality of users. Image preprocessing and text preprocessing are typically also required before feature extraction is performed on the samples (including text and images) in the training sample set. Exemplary image preprocessing includes, but is not limited to, enhancement processing, denoising, resampling, or the like of an image; text preprocessing includes, but is not limited to, word segmentation, part-of-speech tagging, and the like.

And then, respectively extracting the characteristics of the text and the image included in the training sample set.

And then, respectively inputting the extracted text features and the extracted image features into a convolutional neural network, and acquiring the oral health condition predicted by the convolutional neural network.

Then, the method goes into the step of repeatedly determining whether the marked oral health condition accords with the oral health condition predicted by the model; and in response to the fact that the marked oral health condition does not accord with the oral health condition predicted by the model, iteratively updating the weight of the convolutional neural network until the marked oral health condition accords with the oral health condition predicted by the model, and taking the model obtained through training at the moment as an oral health prediction model.

302. The mobile terminal determines the coverage rate and the uniformity of the brushing process of the user according to the number of brushing angles in the brushing process of the user and the stay time under each brushing angle.

In one possible implementation, the embodiment of the application determines coverage by:

Firstly, acquiring the number of brushing angles covered in the brushing process of a user; thereafter, coverage is determined based on the number of brushing angles covered and the total number of brushing angles.

Illustratively, embodiments of the present application will cover the ratio of the number of brushing angles covered to the total number of brushing angles as coverage. Taking the foregoing example of 8 total brushing angles, n being the number of covered brushing angles, n=7, the coverage f=the number of covered brushing angles/total number of brushing angles=n/8=7/8.

In another possible implementation, the embodiment of the present application determines the uniformity rate by:

Firstly, acquiring actual residence time under each tooth brushing angle and residence time proportion under each tooth brushing angle in the tooth brushing process of a user; and then determining the uniformity according to the duration of the brushing process, the actual residence time under each brushing angle and the residence time proportion.

Illustratively, uniformity a = sum of actual residence time per brushing angle/sum of residence time ratio per brushing angle.

Assuming that the total number of brushing angles is 8 as described above, the ratio of residence time at each brushing angle is-left lateral side: right outer side: positive outer side: the duration of the brushing process is 120 seconds, and the actual residence time corresponding to the left outer side, the right outer side, the left inner side, the right inner side, the upper occlusal surface and the lower occlusal surface is 18 seconds, 20 seconds, 15 seconds, 10 seconds, 9 seconds, 26 seconds, 13 seconds and 5 seconds in sequence, namely 1/7, 1/14, and the calculation formula of the uniformity rate a is as follows:

(18+20+15+10+9+26+13+5)/[120*(1/7)+120*(1/7)+120*(1/7)+120*(1/7)+120

*(1/7)+120*(1/7)+120*(1/14)+120*(1/14)]＝116/[120*(1/7)*6+120*(1/14)*2]

＝116/[120*(0.8571+0.1428)]＝116/119.988＝0.9667。

In another possible implementation, the embodiment of the present application may further determine the target residence time at each brushing angle based on the total number of brushing angles and the duration of the brushing session.

Illustratively, embodiments of the present application determine a target residence time at each brushing angle based on the location of the area covered by each brushing angle, the duration, and the total number of brushing angles. For example, to achieve a better cleaning result, the target dwell time on the inner and outer sides of the tooth is longer than the target dwell time on the occlusal surface of the tooth.

For example, assuming a target total duration of 2 minutes is set, the target residence time period apportioned to each brushing angle may be: left lateral side 18 seconds, right lateral side 18 seconds, left medial side 18 seconds, right medial side 18 seconds, upper occlusal side 6 seconds, lower occlusal side 6 seconds. If the actual residence time of the user on the occlusal surface exceeds 6 seconds, the electric toothbrush can carry out voice reminding; or the mobile terminal can also carry out text reminding or voice reminding on the user through the target APP. By the mode, a user can be timely reminded of adjusting the tooth brushing angle, and further the coverage rate and the uniformity of the tooth brushing process are improved.

303. The mobile terminal scores the brushing action of the user according to the duration, overpressure times, coverage rate and uniformity of the brushing process of the user.

In one possible implementation, scoring the user's brushing motion includes the steps of:

3031. scoring the duration of the brushing session for the user to obtain a duration score.

1. And under the condition that the duration time is greater than or equal to the target total duration time, taking the set duration time scoring upper limit as a duration time score.

Taking the target total duration of 2 minutes, the full score of tooth brushing scoring as 100 minutes, the upper limit of the duration score as 48 minutes, the upper limit of the coverage rate score as 26 minutes and the upper limit of the uniformity rate score as 26 minutes as an example, if the duration (the actual total duration of tooth brushing) is longer than 2 minutes, the obtained duration score is 48 minutes.

2. And under the condition that the duration is smaller than the target total duration, determining a duration score according to the difference between the duration and the target total duration.

Illustratively, for this case, the duration score may be determined by:

2-1, determining a duration weight according to the duration and the target total duration; and weighting the upper limit of the time length scoring according to the determined time length weight to obtain the time length score.

Taking the example that the target total duration is 4 minutes, the duration is 2 minutes, and the upper limit of the duration score is 48 minutes, the duration score at this time is 2/4×48=24 minutes.

2-2, Determining a first deduction total score according to the time difference between the target total duration and the deduction score corresponding to a single time unit; and taking the difference between the upper time length scoring limit and the first deduction total score as a time length score.

In the embodiment of the application, the time unit is second, and then the single time unit is 1 second. Illustratively, the corresponding deduction value for a single time unit may be set to 2.5 seconds, which is not limited by the present application.

Taking a deduction value corresponding to a single time unit as an example, the deduction value is 2.5 seconds, and every 1 second less from the target total duration, the deduction value is 2.5 minutes on the basis of the upper limit of the duration score.

3032. And scoring the coverage rate of the user in the brushing process to obtain a coverage rate score.

Taking the coverage score upper limit as 26 as an example, the coverage score is 26×f. Assuming a coverage of 7/8, the coverage score=26× (7/8) =22.75 minutes, and rounding to reserve a fraction of one bit is 22.8 minutes.

3033. Scoring the uniformity of the user during brushing to obtain a uniformity score.

Taking the upper uniformity score limit as 26 as an example, the uniformity score is 26×a. Assuming a uniformity of 0.9667, the uniformity score=26×0.9667= 25.1342, and the rounding to a fraction of one bit is 25.1 points.

3034. And adjusting the sum of the time length score, the coverage rate score and the uniformity score according to the overpressure times of the user in the tooth brushing process to obtain a scoring result.

Illustratively, embodiments of the present application adjust the sum of the duration score, coverage score, and uniformity score by:

firstly, determining a second deduction total score according to the number of times of overvoltage and the deduction score corresponding to single overvoltage;

And then, taking the difference between the sum of the duration score, the coverage rate score and the uniformity rate score and the second deduction total score as a final scoring result.

Taking the deduction value corresponding to single overvoltage as an example, assuming that the number of times of overvoltage is 1 time, the duration score is 48 times, the coverage rate score is 22.8 times, and the uniformity rate score is 25.1 times, the final scoring result is 48+22.8+25.1-5=90.9 times.

304. The mobile terminal outputs a scoring result for the user's brushing motion.

In one possible implementation, the scoring results are output, including but not limited to, the following:

For another example, the user can view the tooth brushing scoring report through the APP for managing the electric toothbrush installed on the mobile terminal, so that the user can know the tooth brushing skill of the user in detail and improve the tooth brushing skill, and the user is greatly improved.

For example, the scoring standard can be adjusted according to the oral health requirement and the tooth brushing behavior data of the user, so that more targeted guidance is provided for the user, and the self requirement of the user is met. For example, the upper time score limit, the upper coverage score limit, the upper uniformity score limit, or the like is adjusted according to the oral health needs of the user. For another example, the target residence time at each brushing angle is adjusted based on the brushing behavior data of the user.
