Referring to fig. 2, fig. 2 is a flowchart illustrating an implementation of a method for adjusting an operation parameter of an electric toothbrush according to an embodiment of the present application. In the embodiment of the application, the execution main body of the operation parameter adjustment method of the electric toothbrush is the electric toothbrush.

As shown in fig. 2, the method for adjusting the operation parameters of the electric toothbrush according to an embodiment of the present application may include S101 to S102, which are described in detail as follows:

in S101, when it is detected that a user brushes teeth with an electric toothbrush, motion information of the electric toothbrush and first posture information of the user are acquired.

In this application embodiment, in order to improve user's effect of brushing teeth, improve user experience, electric toothbrush is when detecting that the user uses electric toothbrush to brush teeth, can acquire electric toothbrush's motion information and user's first gesture information.

In one embodiment of the present application, the electric toothbrush can detect whether the user brushes his or her teeth using the electric toothbrush specifically through S201 to S203 as shown in fig. 3, as follows:

in S201, a pressure signal fed back by a pressure sensor in the electric toothbrush in a set time period is read, and brushing force of the electric toothbrush is determined according to the pressure signal.

In this embodiment, the pressure sensor is installed inside the electric toothbrush, so that the electric toothbrush can read a pressure signal fed back by the pressure sensor located inside within a set period of time, and determine brushing force of the electric toothbrush according to the pressure signal. The set duration may be set according to actual needs, which is not limited herein.

In practical application, the brush head of the electric toothbrush is located inside the cavity of the user and contacts with the teeth of the user during brushing, so that pressure is generated, and therefore, the pressure sensor can be installed at the brush head.

Based on the pressure signal, the electric toothbrush can read the pressure signal which is fed back by the pressure sensor at the brush head in a set time period and is generated after the brush head touches the teeth of the user, and the brushing force of the electric toothbrush is determined according to the pressure signal.

In S202, an acceleration signal fed back by an acceleration sensor in the electric toothbrush in the set time period is read, and second posture information of the user is determined according to the acceleration signal.

In this embodiment, the acceleration sensor is installed inside the electric toothbrush, so the electric toothbrush can read an acceleration signal fed back by the acceleration sensor located inside within a set period of time, and determine the second posture information of the user according to the acceleration signal.

In practical application, when a user holds the electric toothbrush to start brushing teeth, the arm of the user will generate a lifting posture and a lowering posture along with the brushing process, and at this time, the electric toothbrush will swing up and down along with the arm of the user, so the acceleration sensor may be mounted at the handle of the electric toothbrush.

Based on the above, the electric toothbrush can read the acceleration signal fed back by the acceleration sensor at the handle in a set time period, and determine the second gesture information of the user according to the acceleration signal.

In one embodiment of the present application, when the acceleration sensor is a multi-axis acceleration sensor (e.g., a tri-axis sensor), the acceleration signal may include a plurality of acceleration component signals in different directions, so that the electric toothbrush may determine the second posture information of the user through S301 to S302 as shown in fig. 4, which is described in detail as follows:

in S301, the acceleration component signals of the plurality of different directions are synthesized as an acceleration total signal.

In S302, the second posture information is determined according to the acceleration total signal.

In this embodiment, in order to determine the second posture information of the user, the electric toothbrush may combine the acceleration component signals of a plurality of different directions into an acceleration total signal, and determine the second posture information of the user according to the acceleration total signal.

In some possible embodiments, the gesture of the user may be a lifting gesture and a lowering gesture, where the lifting gesture and the lowering gesture may cause a significant change in a lateral (i.e. X-axis) acceleration component signal and a vertical (i.e. Z-axis) acceleration component signal in the multi-axis acceleration sensor, and at the same time, since waveforms of acceleration component signals generated by the lifting gesture of the left hand and the lowering gesture of the right hand are the same, the electric toothbrush may combine the lateral acceleration component signal and the vertical acceleration component signal to obtain an acceleration total signal.

Specifically, the electric toothbrush can synthesize an acceleration total signal according to the following formula:

S＝X ² +Z ² ；

wherein S represents an acceleration total signal, X represents a lateral acceleration component signal, and Z represents a vertical acceleration component signal.

For example, referring to fig. 5, fig. 5 is a graph of acceleration component signals in a plurality of different directions collected by an acceleration sensor according to an embodiment of the present application. As shown in fig. 5, a curve X represents a lateral (i.e., X-axis) acceleration component signal, a curve Y represents a lateral (i.e., Y-axis) acceleration component signal, a curve Z represents a lateral (i.e., Z-axis) acceleration component signal, and a curve a represents a resultant acceleration total signal.

In one embodiment of the present application, in conjunction with S301 to S302, the electric toothbrush may specifically determine the second posture information of the user by the following steps, which are described in detail as follows:

calculating a time difference between the first time and the second time;

In this embodiment, in conjunction with fig. 5, since the user's lifted gesture appears in the graph as: the wave crest is generated firstly, then the wave trough is generated, and the put-down gesture of the user is expressed as follows in the graph: the wave trough is generated firstly, and then the wave crest is generated, so that after the electric toothbrush obtains the acceleration total signal after the acceleration component signals in a plurality of different directions are synthesized, the maximum signal value, the minimum signal value, the first time corresponding to the maximum signal value and the second time corresponding to the minimum signal value in the curve corresponding to the acceleration total signal can be determined, and the time difference between the first time and the second time is calculated.

Based on this, the electric toothbrush can determine the user second posture information based on the maximum signal value, the minimum signal value, and the time difference.

Specifically, the electric toothbrush may determine that the user has a raised posture and a lowered posture when it is detected that the maximum signal value is greater than the seventh threshold, the minimum signal value is greater than the eighth threshold, and the time difference value is less than or equal to the ninth threshold. The seventh threshold, the eighth threshold, and the ninth threshold may be set according to actual needs, which are not limited herein.

The seventh threshold value is larger than the eighth threshold value.

In this embodiment, after determining the second posture information of the user, the electric toothbrush may compare the brushing force with the first threshold value, and detect whether the second posture information of the user meets the setting condition. The first threshold may be set according to actual needs, and is not limited herein.

The setting conditions may be: creating a raised position and a lowered position.

Based on this, in one embodiment of the present application, when the electric toothbrush detects that the brushing force is greater than the first threshold value and the second posture information of the user meets the set condition, step S203 may be performed.

In another embodiment of the present application, the electric toothbrush may determine that the user is not brushing with the electric toothbrush when it is detected that the brushing force is less than or equal to the first threshold value, and/or the second posture information of the user is not in compliance with the set condition.

In S203, if it is detected that the brushing force is greater than a first threshold and the second posture information meets a set condition, it is determined that the user brushes teeth using the electric toothbrush.

In this embodiment, when the electric toothbrush detects that the brushing force is greater than the first threshold and the second posture information of the user meets the set condition, it is indicated that the user has generated brushing behavior, and the brush head of the electric toothbrush touches the teeth of the user and generates pressure for brushing teeth, so that the electric toothbrush can determine that the user uses the electric toothbrush to brush teeth.

In S102, an operating parameter of the electric toothbrush is adjusted according to the motion information and the first posture information.

In one embodiment of the present application, in order to improve the working efficiency, the electric toothbrush may directly calculate a first difference between the acquired motion information of the electric toothbrush itself and the reference motion information stored in the electric toothbrush itself, and calculate a second difference between the first posture information of the user and the reference posture information stored in the electric toothbrush itself. Wherein the reference motion information and the reference posture information may be set according to actual needs, without limitation.

In this embodiment, the electric toothbrush may compare the first difference with a second threshold and the second difference with a third threshold after the first difference and the second difference are obtained. The second threshold and the third threshold may be set according to actual needs, and are not limited herein.

In this embodiment, when the electric toothbrush detects that the first difference value is greater than or equal to the second threshold value and/or the second difference value is greater than or equal to the third threshold value, it indicates that the motion information of the electric toothbrush and the reference motion information are greatly different, and/or the first gesture information of the user is greatly different from the reference gesture information, so that in order to improve the user experience and the brushing effect, the electric toothbrush can adjust the operation parameters of the electric toothbrush according to the reference motion information and the reference gesture information.

In another embodiment of the present application, to further improve the user experience and improve the adjustment accuracy, the electric toothbrush may further perform steps S401 to S403 as shown in fig. 6.

As can be seen from the above, according to the method for adjusting the operation parameters of the electric toothbrush provided by the embodiment of the application, when detecting that a user brushes teeth with the electric toothbrush, motion information of the electric toothbrush and first posture information of the user are obtained; the operating parameters of the electric toothbrush are adjusted based on the motion information and the first pose information. Compared with the prior art that the operation parameters are adjusted only according to tooth brushing force, the method needs to be combined with the motion information of the electric toothbrush and the gesture information of the user to adjust the operation parameters of the electric toothbrush, that is, when the operation parameters of the electric toothbrush are adjusted, the method considers not only the influence of the motion information of the electric toothbrush on the operation parameters of the electric toothbrush, but also the influence of the gesture information of the user on the operation parameters of the electric toothbrush, so that the accuracy of adjusting the operation parameters of the electric toothbrush is improved.

Referring to fig. 6, fig. 6 is a schematic diagram illustrating a method for adjusting an operating parameter of an electric toothbrush according to another embodiment of the present disclosure. In practical applications, the electric toothbrush cannot process a large amount of data, and in order to further improve the user experience, improve the accuracy of adjusting the operation parameters of the electric toothbrush, and improve the brushing effect of the user, step S102 may specifically include steps S401 to S403 shown in fig. 6, which are described in detail below, with respect to the embodiment corresponding to fig. 1:

In S401, the motion information and the first gesture information are transmitted to a user terminal.

In S402, receiving brushing experience scores of a plurality of different dimensions sent by the user terminal; the brushing experience scores in the different dimensions are calculated by the user terminal according to the motion information and the first gesture information.

In S403, according to the brushing experience scores of the plurality of different dimensions, the operation parameters of the electric toothbrush corresponding to the plurality of different dimensions are adjusted, and adjustment advice information for the brushing behavior of the user is output.

In this embodiment, the electric toothbrush may send the acquired motion information and the first gesture information of the user to a user terminal connected to the electric toothbrush through wireless communication of the bluetooth module for processing.

After obtaining the motion information and the first gesture information, the user terminal can calculate and obtain brushing experience scores with different dimensions according to the motion information and the first gesture information.

The first gesture information is used for describing the brushing behaviors of the user, and therefore the dimensions include, but are not limited to, a toothbrush vibration frequency dimension, a gum overpressure protection dimension, a different-part cleaning force dimension, a hand-held gesture dimension, a tooth cleaning coverage dimension and a user behavior habit dimension.

Specifically, the user terminal may calculate a brushing experience score in a toothbrush vibration frequency dimension according to the vibration frequency and a pre-stored frequency threshold, calculate a brushing experience score in a gum overpressure protection dimension according to a brushing force and a pre-stored pressure threshold, calculate brushing experience scores in different location cleaning force dimensions according to a brushing force, a brushing trajectory, a brushing duration, and a pre-stored time threshold, pressure threshold, calculate a brushing experience score in a hand-held gesture dimension according to the first gesture information and the pre-stored set gesture information, and calculate a brushing experience score in a user behavior habit dimension according to a brushing trajectory and a pre-stored range threshold.

After the user terminal calculates the brushing experience scores in the multiple different dimensions, the brushing experience scores in the multiple different dimensions can be sent to the electric toothbrush.

After receiving the brushing experience scores in the plurality of different dimensions, the electric toothbrush can compare the brushing experience scores in the plurality of different dimensions with the set scores one by one. The set score may be set according to actual needs, and is not limited herein.

In this embodiment, the electric toothbrush can adjust the vibration frequency of the electric toothbrush when it is detected that the brushing experience score in the vibration frequency dimension of the toothbrush is less than the set score.

The electric toothbrush is less than the setting score in detecting the tooth brushing experience score in the gum overvoltage protection dimension, and the tooth brushing force of the electric toothbrush can be adjusted.

The electric toothbrush detects that the tooth brushing experience score on the cleaning force dimension of different parts is smaller than the set score, and the tooth brushing force, the tooth brushing track and the tooth brushing time length of the electric toothbrush can be adjusted.

The electric toothbrush can adjust the brushing track of the electric toothbrush when the electric toothbrush detects that the brushing experience score in the dimension of the tooth cleaning coverage is smaller than the set score.

The electric toothbrush may output adjustment advice information for the user's brushing behavior upon detecting that the brushing experience score in the handheld gesture dimension and/or in the user behavior habit dimension is less than the set score.

As can be seen from the above, the method for adjusting the operation parameters of the electric toothbrush according to the present embodiment transmits the motion information and the first posture information to the user terminal; receiving a plurality of tooth brushing experience scores with different dimensions sent by a user terminal; the tooth brushing experience scores in different dimensions are calculated by the user terminal according to the motion information and the first posture information; according to the tooth brushing experience scores of the plurality of different dimensions, the operation parameters of the electric toothbrush corresponding to the plurality of different dimensions are adjusted, and adjustment suggestion information for the tooth brushing behaviors of the user is output. By adopting the method, through the data interaction between the electric toothbrush and the user terminal, the electric toothbrush can receive the tooth brushing experience scores in a plurality of different dimensions, which are obtained through the processing of big data (such as the motion information of the electric toothbrush and the first gesture information of the user) by the user terminal, adjust the operation parameters of the electric toothbrush corresponding to the plurality of different dimensions based on the tooth brushing experience scores, and output the adjustment suggestion information for the tooth brushing behaviors of the user, so that the user can adjust the tooth brushing behaviors independently according to the adjustment suggestion information, the user experience is improved, and the tooth brushing effect is improved.

In still another embodiment of the present application, after the motion information of the electric toothbrush and the first posture information of the user are obtained, the electric toothbrush may compare the brushing force in the motion information with the fourth threshold value, the fifth threshold value, and the sixth threshold value, respectively, because the motion information includes the brushing force. The fourth threshold, the fifth threshold and the sixth threshold may be set according to actual needs, which is not limited herein.

The fifth threshold value is smaller than the fourth threshold value, and the sixth threshold value is larger than the fourth threshold value.

In this embodiment, the electric toothbrush may perform step S501 shown in fig. 7 when it detects that the brushing force of the motion information is greater than the fourth threshold.

When the electric toothbrush detects that the brushing force of the motion information is less than the fifth threshold, step S502 shown in fig. 7 may be performed.

When the electric toothbrush detects that the brushing force of the motion information is greater than the sixth threshold, step S503 as shown in fig. 7 may be performed.

Based on this, referring to fig. 7, fig. 7 is a schematic diagram showing a method for adjusting an operation parameter of an electric toothbrush according to another embodiment of the present disclosure. With respect to the corresponding embodiment of fig. 1, after S101, the electric toothbrush may further include S501 to S503 as shown in fig. 7, as follows:

In S501, if the brushing force in the motion information is greater than a fourth threshold, the vibration frequency of the electric toothbrush is reduced.

In this embodiment, when the electric toothbrush detects that the brushing force of the motion information is greater than the fourth threshold, it indicates that the pressure born by the teeth exceeds the safety range, which may cause discomfort to the user, so that the electric toothbrush may reduce the vibration frequency of the electric toothbrush, that is, the vibration frequency of the vibration motor in the electric toothbrush.

In S502, if the brushing force in the motion information is less than a fifth threshold value, increasing the vibration frequency of the electric toothbrush; the fifth threshold is less than the fourth threshold.

In this embodiment, when the electric toothbrush detects that the brushing force of the motion information is less than the fifth threshold, it indicates that the brushing force is insufficient and the teeth cannot be cleaned, so that in order to improve the tooth cleaning rate, the electric toothbrush may improve the vibration frequency of the electric toothbrush, that is, the vibration frequency of the vibration motor in the electric toothbrush.

In S503, if the brushing force in the motion information is greater than a sixth threshold, controlling the electric toothbrush to stop vibrating; the sixth threshold is greater than the fourth threshold.

In this embodiment, when the electric toothbrush detects that the brushing force of the motion information is greater than the sixth threshold, it indicates that the brushing force is too great, that is, the pressure borne by the gums of the user is too great, so that in order to avoid gum damage, the electric toothbrush may reduce the vibration frequency of the electric toothbrush, that is, the vibration frequency of the vibration motor in the electric toothbrush.

As can be seen from the above, in the method for adjusting the operation parameters of the electric toothbrush according to the present embodiment, when detecting that the user brushes with the electric toothbrush, after motion information of the electric toothbrush and first posture information of the user are obtained, when detecting that brushing force in the motion information is greater than a fourth threshold, vibration frequency of the electric toothbrush is reduced, pressure born by gums of the user is prevented from exceeding a safety range, and user experience is reduced; when the tooth brushing force in the motion information is detected to be smaller than a fifth threshold value, the vibration frequency of the electric toothbrush is increased, and the situation that the teeth cannot be cleaned due to too small pressure born by the gums of the user is avoided; the fifth threshold is less than the fourth threshold; when the brushing force in the motion information is detected to be greater than a sixth threshold value, controlling the electric toothbrush to stop vibrating; thereby avoiding the gum from being damaged due to the overlarge pressure.

It should be understood that the sequence number of each step in the foregoing embodiment does not mean that the execution sequence of each process should be determined by the function and the internal logic of each process, and should not limit the implementation process of the embodiment of the present application in any way.
