[0042] See also Figures 1 to 3 In some embodiments of the present application, a method for controlling a smart toothbrush 10 provided by the present application comprises the following steps:

[0043] Obtaining angle parameters of the toothbrush body 11;

[0044] The operating parameters of the power module 22 are controlled according to the angle parameters, so that the power module 22 drives the toothbrush head 12 to move according to the operating parameters.

[0045] When the toothbrush head 12 cleans teeth at different positions in the oral cavity, the posture angle of the toothbrush body 11 will be different. Then, the operating parameters of the power module 22 that drives the toothbrush head 12 can be controlled by detecting the angle parameters of the toothbrush body 11, so that the operating parameters of the power module 22 can adapt to the cleaning needs of different parts of teeth and different parts of teeth.

[0046] Since the degree of wear, dirtiness and cleaning difficulty of teeth in different parts and different parts of teeth may be different, it is necessary to match different operating parameters of the power module 22 according to the different parts of teeth and different parts of teeth, so that the smart toothbrush 10 can perform targeted cleaning according to the different parts of teeth and different parts of teeth. In this way, the teeth cleaning effect is improved during the teeth cleaning process and the user's teeth cleaning experience is improved.

[0047] In some embodiments of the present application, controlling the operating parameters of the power module 22 according to the angle parameters includes:

[0048] Determine the brushing position of the toothbrush head 12 according to the angle parameter;

[0049] The operating parameters of the power module 22 are controlled according to the brushing position.

[0050] For different brushing positions, the angle parameters of the toothbrush body 11 and the operation of the power module 22 will be different. After the angle parameters of the toothbrush body 11 are detected, the brushing position of the toothbrush head 12 is determined according to the angle parameters, so that different operation parameters are matched according to the current brushing position of the toothbrush head 12, and the operation of the power module 22 is controlled according to different operation parameters, so that the action of the toothbrush head 12 can adapt to the current brushing position and meet the teeth cleaning needs of the current brushing position.

[0051] In some embodiments of the present application, the tooth brushing position includes the growth position of the tooth contacted by the toothbrush head 12 and / or the contact position between the tooth and the toothbrush head 12 after the toothbrush head 12 contacts the tooth.

[0052] According to the growth position law of teeth, the tooth growth areas can be divided into four areas: upper left row, upper right row, lower left row, and lower right row. The name and arrangement order of the teeth in each area are: counting from the midline, the first is the central incisor (also called incisor), the second is the lateral incisor, the third is the canine (also called canine tooth), the fourth is the first premolar (also called first bicuspid), the fifth is the second premolar (also called second bicuspid), the sixth is the first molar, the seventh is the second molar, and the eighth is the third molar (also called wisdom tooth).

[0053] Different teeth grow in different positions, so the growth positions of different teeth can be defined and numbered separately.

[0054] Specifically, the growth positions of different teeth are defined as follows:

[0055] Upper left central incisor, upper left left incisor, upper left canine, upper left first premolar, upper left second premolar, upper left first molar, upper left second molar, upper left third molar, upper right central incisor, upper right right incisor, upper right canine, upper right first premolar, upper right second premolar, upper right first molar, upper right second molar, upper right third molar, lower left central incisor, lower left left incisor, lower left canine, lower left first premolar, lower left second premolar, lower left first molar, lower left second molar, lower left third molar, lower right central incisor, lower right right incisor, lower right canine, lower right first premolar, lower right second premolar, lower right first molar, lower right second molar, lower right third molar.

[0056] The contact positions include the inner side, outer side, and occlusal surface of the teeth. For incisors, there are inner and outer sides; for molars, there are inner, outer, and occlusal surfaces.

[0057] When the toothbrush head 12 works at different growth positions and contact positions, the angle of the toothbrush body 11 will be different, and the corresponding angle parameters will be different. A database of the angle of the toothbrush body 11 can be established for different growth positions and contact positions, and different angle data of the toothbrush body 11 correspond to different operating parameter data. During the operation of the smart toothbrush 10, after obtaining the angle parameters of the toothbrush body 11, the angle data of the toothbrush body 11 in the database can be matched according to the real-time angle parameters, and then the corresponding operating parameters can be adapted, so as to control the operation of the power module 22 according to the corresponding operating parameters, and the toothbrush head 12 can be driven by the power module 22 to move, so that the smart toothbrush 10 can perform targeted cleaning according to different parts of the teeth and different parts of the teeth, thereby improving the tooth cleaning effect during the tooth cleaning process and improving the user's tooth cleaning experience.

[0058] In some embodiments of the present application, obtaining the angle parameter of the toothbrush body 11 includes the following steps:

[0059] Acquire initial angle data of the toothbrush body 11;

[0060] Acquire real-time angle data of the toothbrush body 11;

[0061] Calculate the difference data between the real-time angle data and the initial angle data;

[0062] Angle parameters are determined from the difference data.

[0063] It is understandable that different users hold the toothbrush in different ways, which results in different initial angle data of the toothbrush body 11 when different users pick up the toothbrush. Moreover, the same user will also have different initial angle data of the toothbrush body 11 each time he or she picks up the toothbrush due to different gripping positions and angles.

[0064] When the user picks up the toothbrush and starts the toothbrush, it indicates that the user has grasped the toothbrush well. At this time, the angle data of the toothbrush body 11 is recorded, and this angle data is the initial angle data of the toothbrush body 11.

[0065] When the user is cleaning teeth, the posture and angle of the toothbrush body 11 will be different when cleaning teeth in different positions and different positions of teeth, resulting in the real-time angle data of the toothbrush body 11 changing in real time with the different teeth and different positions of teeth during the teeth cleaning process.

[0066] During the user's teeth cleaning process, by calculating the difference data between the real-time angle data and the initial angle data, the influence of the differences in the user's gripping position, gripping angle, gripping posture, etc. when picking up the toothbrush is reduced, and the position of the tooth where the current toothbrush head 12 is located can be more accurately determined. According to the calculated difference data, the angle parameters of the toothbrush body 11 can be determined, and the operating parameters of the power module 22 can be controlled according to the angle parameters, so that the power module 22 drives the toothbrush head 12 to move according to the operating parameters, so that the toothbrush head 12 can perform adaptive actions at the current position, so that the action of the toothbrush head 12 can adapt to the cleaning of the current tooth position, thereby ensuring the cleaning effect on the teeth and improving the user's teeth cleaning experience.

[0067] In some embodiments of the present application, obtaining the initial angle data of the toothbrush body 11 includes the following steps:

[0068] Acquire data of the pressing position of the user's finger on the toothbrush body 11 when the user holds the toothbrush;

[0069] The initial angle data of the toothbrush body 11 is acquired based on the pressed position data.

[0070] Pressing force detection sensors can be set at different positions of the toothbrush body 11 to detect the gripping force and gripping position of the toothbrush when the user grips the toothbrush. Different gripping positions will lead to differences in the gripping position, gripping angle, gripping posture, etc. when the user picks up the toothbrush, so by obtaining the data of the pressing position of the user's fingers on the toothbrush body 11 when the user grips the toothbrush, the initial angle data of the toothbrush body 11 after the user picks up the toothbrush can be calculated.

[0071] A database of pressing position data and initial angle data may also be preset, and after obtaining the pressing position data, the initial angle data of the toothbrush body 11 may be obtained by querying the database.

[0072] In some embodiments of the present application, before a user uses the smart toothbrush 10 to clean teeth, the angle parameter is calibrated. The step of calibrating the angle parameter includes:

[0073] Instruct the user to stop at different positions of teeth and different positions of teeth in sequence;

[0074] Acquire real-time calibration angle data of the toothbrush body 11 during the stay;

[0075] Record each real-time calibration angle data, and associate each real-time calibration angle data with the number of the corresponding tooth part, thereby forming associated data;

[0076] An angle parameter database is established based on the associated data.

[0077] The shape and growth angle of the teeth at the same corresponding position of each user will be different. Before the user uses the smart toothbrush 10, an angle parameter database is established in advance according to the characteristics of the user's teeth through real-time simulation, and then the angle parameters are calibrated, so that the smart toothbrush 10 can adapt to the personalized characteristics of the user's teeth to control the movement of the toothbrush head 12, thereby ensuring the cleaning effect of the teeth and improving the user's tooth cleaning experience.

[0078] In some embodiments of the present application, the operating parameters of the power module 22 are controlled according to the brushing position, including:

[0079] Choose the brushing mode based on the brushing position;

[0080] The operating parameters of the power module 22 are controlled according to the brushing mode.

[0081] In some embodiments of the present application, the operating parameters include at least one of vibration frequency, vibration amplitude, brushing force or vibration angle.

[0082] Since different teeth and different parts of teeth are adapted to different vibration frequencies, vibration amplitudes, brushing forces or vibration angles, different brushing modes can correspond to different operating parameters. When it is calculated that the toothbrush head 12 is in a certain brushing position, the corresponding brushing mode is selected according to the brushing position at this time, and then the operating parameters of the power module 22 are controlled according to the current brushing mode. In this way, the brushing mode is switched in real time during the tooth cleaning process, and the operating parameters are controlled in real time, so that the action of the toothbrush head 12 can adapt to different brushing positions, thereby ensuring the cleaning effect on the teeth and improving the user's tooth cleaning experience.

[0083] On the other hand, see Figure 4 The present application also provides a smart toothbrush control system 20, which is controlled by the smart toothbrush 10 control method, and includes: an angle detection module 21, a power module 22, and a control module 23. The angle detection module 21 is used to detect the angle parameter of the toothbrush body 11. The power module 22 is used to drive the toothbrush head 12 to move. The control module 23 is configured to receive the angle parameter and control the operating parameters of the power module 22 according to the angle parameter.

[0084] In some embodiments of the present application, the angle detection module 21 includes at least one of a gyroscope or a Hall sensor.

[0085] In some embodiments of the present application, the control module 23 is preset with a brushing mode control program, and the control module 23 is configured to call the brushing mode control program according to the angle parameters and control the operating parameters according to the brushing mode control program.

[0086] When the toothbrush head 12 is used to clean teeth at different positions in the oral cavity, the posture angle of the toothbrush body 11 will be different. During the toothbrush cleaning process, the angle parameters of the smart toothbrush 10 are detected in real time by the angle detection module 21, and the control module 23 controls the operating parameters of the power module 22 that drives the toothbrush head 12 according to the angle parameters of the toothbrush body 11, so that the operating parameters of the power module 22 can adapt to the cleaning needs of different parts of teeth and different parts of teeth.

[0087] Since the degree of wear, dirtiness and cleaning difficulty of teeth in different parts and different parts of teeth may be different, it is necessary to match different operating parameters of the power module 22 according to the different parts of teeth and different parts of teeth, so that the smart toothbrush 10 can perform targeted cleaning according to the different parts of teeth and different parts of teeth. In this way, the teeth cleaning effect is improved during the teeth cleaning process and the user's teeth cleaning experience is improved.

[0088] In some embodiments of the present application, the control system of the smart toothbrush 10 further includes a pressure sensor 24 for detecting pressure parameters of the toothbrush head 12 on the teeth. The control module 23 is configured to control the operating parameters of the power module 22 according to at least one of the angle parameter or the pressure parameter.

[0089] When different users use the smart toothbrush 10 to clean their teeth, the pressure applied by the toothbrush head 12 to the teeth by the user will be different. The pressure that different users' teeth and different parts of teeth can withstand is different. In the process of cleaning teeth, the pressure parameters of the toothbrush head 12 on the teeth are detected by the pressure sensor 24, and the operating parameters of the power module 22 are controlled according to the angle parameters and the pressure parameters, so that the action of the toothbrush head 12 can adapt to different brushing conditions, improve the cleaning effect during the cleaning process, and improve the user's cleaning experience.

[0090] In some embodiments of the present application, a pressure threshold can also be set. When it is detected that the pressure parameter exceeds the pressure threshold, an alarm is issued or the brushing action is paused to prevent the user's teeth from being damaged due to excessive pressure during brushing, thereby protecting the user's teeth.

[0091] On the other hand, see Figure 5 The present application also provides a smart toothbrush 10, comprising: a toothbrush body 11, a toothbrush head 12 and a smart toothbrush control system 20. The toothbrush head 12 is mounted on the toothbrush body 11, and the smart toothbrush control system 20 is used to control at least one of the vibration frequency, vibration amplitude, brushing force or vibration angle of the smart toothbrush 10.
