[0012] In order to make the purpose, technical solutions and advantages of one or more embodiments of this specification clearer, the technical solutions of one or more embodiments of this specification will be clearly and completely described below in combination with the specific embodiments of this specification and the corresponding drawings. Obviously, the described embodiments are only part of the embodiments of this specification, not all of the embodiments. Based on the embodiments in this specification, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of one or more embodiments of this specification.

[0013] The technical solutions provided by the embodiments of this specification are described in detail below in conjunction with the accompanying drawings.

[0014] Figure 1 Schematic diagram of the structure of an oral cleaning device provided in the embodiment of this specification. Figure 1 As shown, an oral cleaning device provided by the present application may include: a brush head 11, a sensor element 12, a controller 13, and a driving device 14. The brush head 11 may include a brush wire area 111. The sensor element 12 may be configured to measure the motion state data of the oral cleaning device. The controller 13 may be configured to determine the posture of the oral cleaning device based on the motion state data; determine the cleaning surface that the brush wire area 111 is facing based on the posture of the oral cleaning device; and output a driving signal corresponding to the cleaning surface that the brush wire area 111 is facing. The driving device 14 may be configured to respond to the driving signal and output a power for driving the brush head 11 to drive the brush wire area 111 to perform a cleaning operation.

[0015] In the embodiment of the present specification, the brush wire area 111 provided on the brush head 11 can be used to clean the teeth in the oral cavity.

[0016] Usually, the controller 13 and the sensor element 12 can be arranged inside the oral cleaning device to avoid damage to the controller 13 and the sensor element 12 during the oral cleaning process. The controller 13 can be used to control the normal operation of the oral cleaning device.

[0017] In an embodiment of the present specification, the operating mode of the oral cleaning device may include a recommended cleaning mode. When the user selects the recommended mode, the sensor element 12 may be used to measure and collect motion state data of the oral cleaning device; the motion state data of the oral cleaning device may be motion data of the oral cleaning device during operation.

[0018] After collecting the motion state data of the oral cleaning device, the sensor element 12 may also send the data to the controller 13. After acquiring the motion state data, the controller 13 may determine the posture of the oral cleaning device according to the motion state data.

[0019] Since the oral cleaning device has different postures when cleaning different cleaning surfaces of the teeth, for example, the angle of the oral cleaning device when cleaning the chewing surface of the teeth is different from the angle of the oral cleaning device when cleaning the side of the teeth. Therefore, the cleaning surface that the brush wire area 111 is cleaning can be determined according to the posture of the oral cleaning device, that is, the cleaning surface that the brush wire area 111 is facing can be determined.

[0020] In the embodiment of this specification, the driving signal output by the controller 13 may be a predetermined signal that has a better cleaning effect for the cleaning surface that the brush area 111 faces; it is used to output corresponding driving signals according to different cleaning surfaces when the user selects the recommended mode. Different cleaning surfaces may correspond to different driving signals.

[0021] In practical applications, the driving device 14 may be a driving motor. The output end of the driving device 14 may be connected to the brush head 11. When the driving device 14 is a driving motor, the output shaft of the driving motor may be used to connect to the brush head 11. The output end of the driving device 14 may move under the action of a driving signal, thereby generating power to drive the brush head 11 to move, and then the brush head 11 may drive the brush filament area 111 to perform a cleaning action.

[0022] In actual applications, different types of oral cleaning devices may have different types of driving devices 14, and the output ends of different types of driving devices 14 may drive the brush head 11 to move in different ways. For example, when the oral cleaning device is a rotary type, the movement mode of the brush head 11 may be a rotary vibration; when the oral cleaning device is a sweeping vibration type, the movement mode of the brush head 11 is a sweeping vibration; when the oral cleaning device is a reciprocating vibration type, the movement mode of the brush head 11 is a reciprocating vibration.

[0023] Since the driving signals corresponding to different cleaning surfaces are different, the motion states of the output end of the driving device 14 are different, and thus the cleaning operations performed by the brush wire area 111 driven by the driving device 14 through the brush head 11 are also different. Specifically, for a rotary oral cleaning device, when the driving signals are different, the speed at which the brush head 11 is driven to rotate by the output end of the driving device 14 in the oral cleaning device is different; for a sweeping vibration oral cleaning device and a high-frequency reciprocating vibration oral cleaning device, when the driving signals are different, at least one of the frequency and amplitude of the brush head 11 driven by the output end of the driving device 14 in the oral cleaning device is different.

[0024] In the embodiment of this specification, the controller 13 is used to determine the cleaning surface of the teeth that the brush wire area 111 of the oral cleaning device faces according to the motion state data of the oral cleaning device collected by the sensor element 12, and outputs a driving signal corresponding to the cleaning surface of the teeth that the brush wire area 111 faces, so that the driving device 14 can respond to the driving signal and output a power corresponding to the cleaning surface of the teeth that the brush wire area 111 faces, which is used to drive the brush head 11 to drive the brush wire area 111 to perform a cleaning operation. Different driving signals are output for different cleaning surfaces, so that different cleaning surfaces can be cleaned with power with better cleaning effect in a targeted manner, thereby improving the oral cleaning effect.

[0025] Optionally, the driving device 14 may be configured to: in response to the driving signal, output power for driving the brush head 11 to vibrate at a fixed frequency.

[0026] The driving signal may be a signal including a waveform signal of only one frequency. Driven by the driving signal, the driving device 14 may drive the brush head 11 and the brush filament area 111 to vibrate at a fixed frequency.

[0027] Optionally, the driving device 14 may be configured to: in response to the driving signal, output power for driving the brush head 11 to vibrate alternately in sequence at a plurality of different frequencies.

[0028] The driving signal may be a signal including signals of multiple frequencies alternating in sequence. Driven by the above driving signal, the driving device 14 may drive the brush head 11 to vibrate at multiple frequencies; the multiple frequencies alternating in sequence.

[0029] In practical applications, the signal characteristic parameters may include duty cycle, frequency, period, etc. In the embodiment of this specification, the controller 13 may control and adjust the output drive signal through the duty cycle and frequency.

[0030] Optionally, the controller 13 can be specifically configured to: determine a first preset duty cycle and a first preset frequency corresponding to the cleaning surface that the brush area 111 is facing, according to the cleaning surface that the brush area 111 is facing; and output a driving signal with a duty cycle of the first preset duty cycle and a frequency of the first preset frequency.

[0031] In the embodiments of this specification, the duty cycle may refer to the ratio of the time during which an electrical signal is output in a signal cycle to the entire signal cycle; in an ideal pulse sequence, the ratio of the duration of a positive pulse to the total pulse cycle. Specifically, the duty cycle of a pulse sequence with a pulse width of 1s and a signal cycle of 4s is 0.25.

[0032] In the embodiment of the present specification, the first preset duty cycle and the first preset frequency corresponding to each cleaning surface may be predetermined parameters of the driving signal that have a better cleaning effect for the corresponding cleaning surface.

[0033] The driving device 14 responds to the driving signal corresponding to the cleaning surface that the brush wire area 111 faces, and can output power with a better cleaning effect for the cleaning surface that the brush wire area 111 faces.

[0034] In actual applications, when the first preset duty cycle and the first preset frequency of the driving signal change, the motion parameters of the driving device 14 will change accordingly. Specifically, for a rotary oral cleaning device, the larger the first preset duty cycle of the driving signal, the larger the rotational torque at the output end of the driving device 14 in the oral cleaning device; the larger the first preset frequency of the driving signal, the faster the rotation speed of the output end of the driving device 14 in the oral cleaning device. For a sweeping vibration oral cleaning device and a high-frequency reciprocating vibration oral cleaning device, the larger the first preset duty cycle of the driving signal, the larger the swing amplitude of the output end of the driving device 14 in the oral cleaning device; the larger the first preset frequency of the driving signal, the higher the swing frequency of the output end of the driving device 14 in the oral cleaning device.

[0035] For ease of understanding, the cleaning surface is also described in the embodiments of this specification.

[0036] Optionally, the cleaning surface may include an occlusal surface 21 , a first tooth side surface 22 , and a second tooth side surface 23 of the teeth in the oral cavity; the first tooth side surface 22 and the second tooth side surface 23 are respectively located on both sides of the occlusal surface 21 .

[0037] Figure 2Schematic diagram of a cleaning surface of teeth in the oral cavity provided in an embodiment of the present specification. Figure 2 As shown, the first tooth side surface 22 may include a lingual side surface 221 and a palatal side surface 222; the lingual side surface 221 may be a tooth surface facing the tongue among the teeth in the lower part of the oral cavity; the palatal side surface 222 may be a tooth surface facing the upper palate among the teeth in the upper part of the oral cavity. The second tooth side surface 23 may include a labial side surface 231 and a buccal side surface 232; the labial side surface 231 may be a tooth surface facing the lips among the teeth in the front part of the oral cavity; the buccal side surface 232 may be a tooth surface facing the cheek among the teeth in the two sides of the oral cavity.

[0038] Optionally, at least two of the driving signals corresponding to the occlusal surface 21 , the driving signals corresponding to the first tooth side surface 22 , and the driving signals corresponding to the second tooth side surface 23 are different.

[0039] In the embodiment of the present specification, at least two of the drive signals corresponding to the occlusal surface 21, the drive signals corresponding to the first tooth side surface 22, and the drive signals corresponding to the second tooth side surface 23 are different. It can be that the drive signals corresponding to the occlusal surface 21, the drive signals corresponding to the first tooth side surface 22, and the drive signals corresponding to the second tooth side surface 23 are all different; it can also be that the drive signal corresponding to the occlusal surface 21 is the same as the drive signal corresponding to the first tooth side surface 22, and different from the drive signal corresponding to the second tooth side surface 23; it can also be that the drive signal corresponding to the occlusal surface 21 is the same as the drive signal corresponding to the second tooth side surface 23, and different from the drive signal corresponding to the first tooth side surface 22; it can also be that the drive signal corresponding to the first tooth side surface 22 is the same as the drive signal corresponding to the second tooth side surface 23, and different from the drive signal corresponding to the occlusal surface 21.

[0040] Next, the drive signals corresponding to the respective cleaning surfaces will be described.

[0041] Optionally, the controller 13 can be specifically configured as follows: if the cleaning surface facing the brush area 111 is the occlusal surface 21, determine a first duty cycle and a first target frequency corresponding to the occlusal surface 21; and output a driving signal with a duty cycle of the first duty cycle and a frequency of the first target frequency.

[0042] Figure 3 is a waveform diagram of a driving signal provided in an embodiment of this specification, such as Figure 3 As shown, Figure 3 The horizontal axis represents time, T represents a signal cycle, and the vertical axis represents the amplitude of the driving signal. Figure 3 The driving signal shown in FIG. 1 is a rectangular wave signal, and the first duty cycle and the first target frequency of the driving signal are fixed. In practical applications, the driving signal may also be a driving signal of other waveforms.

[0043] Specifically, for a sweeping vibration oral cleaning device or a high-frequency reciprocating vibration oral cleaning device, the first duty cycle of the driving signal for cleaning the occlusal surface 21 can be any value between 0.5 and 0.7; the first target frequency can be any value between 260 Hz and 280 Hz. The duty cycle of the driving signal for cleaning the occlusal surface 21 is 0.5 to 0.7, and the power is appropriate, so that the sweeping vibration oral cleaning device can cover the entire tooth surface during the sweeping cleaning process, thereby improving the oral cleaning effect; and the first target frequency of the driving signal for cleaning the occlusal surface 21 is 260 Hz to 280 Hz, which can make the sweeping vibration frequency of the sweeping vibration oral cleaning device more reasonable, clean more thoroughly, and further ensure the cleaning effect.

[0044] In practical applications, the first duty cycle and the first target frequency of other types of oral cleaning devices can be set as needed.

[0045] Optionally, the controller 13 can be specifically configured as: if the cleaning surface facing the brush wire area 111 is the first tooth side surface 22, determine the second duty cycle and the second target frequency corresponding to the first tooth side surface 22; and output a driving signal with a duty cycle of the second duty cycle and a frequency of the second target frequency.

[0046] In the embodiment of the present specification, when the oral cleaning device is used to clean the first tooth side surface 22 of the teeth in the oral cavity, the duty cycle and frequency of the drive signal can also be fixed. The second duty cycle of the drive signal corresponding to the first tooth side surface 22 can be the same as or different from the first duty cycle of the drive signal corresponding to the occlusal surface 21. The second target frequency of the drive signal corresponding to the first tooth side surface 22 can be the same as or different from the second target frequency of the drive signal corresponding to the occlusal surface 21.

[0047] In practical applications, the second duty cycle of the driving signal for cleaning the first tooth side surface 22 of the sweeping vibration oral cleaning device can be 0.4; the first target frequency of the driving signal for cleaning the first tooth side surface 22 can be any value between 280 Hz and 320 Hz. The second duty cycle is 0.4, which allows the sweeping vibration oral cleaning device to cover the entire tooth surface during the sweeping cleaning process, but does not touch the gums, making the amplitude of the sweeping vibration oral cleaning device more reasonable, and avoiding the oral cleaning device from damaging the gums during the cleaning process; the second target frequency is 280 Hz to 320 Hz, which can improve the cleaning effect between the teeth.

[0048] Typically, when a user uses a non-electric oral cleaning device to clean the first tooth side surface 22 and the second tooth side surface 23, in order to ensure the cleaning effect, the speed of the cleaning action may be different for different positions of the teeth; for example, the cleaning action for the root or lower part of the teeth can be slower; for the top or upper part of the teeth, the cleaning action can be faster, so that the plaque on the teeth can be removed from the teeth.

[0049] Based on this, the controller 13 can be specifically configured as follows: if the cleaning surface facing the brush wire area 111 is the first tooth side surface 22, determine a third duty cycle corresponding to the first tooth side surface 22 and a plurality of first tooth side surface 22 frequencies with different frequencies; output a driving signal with a duty cycle of the third duty cycle and a frequency of a plurality of first tooth side surface 22 frequencies alternating in sequence.

[0050] Optionally, the multiple frequencies of the first tooth side surface 22 with different frequencies may include at least a first specified frequency and a second specified frequency; within one signal cycle of the driving signal, the signal of the first specified frequency may last for a first duration, and the signal of the second specified frequency may last for a second duration.

[0051] In the embodiments of the present specification, the third duty cycle may be the same value as the second duty cycle, or a value similar to the second duty cycle, so as to avoid damaging the gums while ensuring the cleaning effect.

[0052] In the embodiment of this specification, the driving signal output by the controller 13 can be a rectangular wave signal or a driving signal of other waveforms. The driving signal can be a periodic signal, and one period of the driving signal includes signals of multiple frequencies, and the signals of multiple frequencies alternate in sequence.

[0053] Figure 4 is a waveform diagram of a driving signal provided in an embodiment of this specification, such as Figure 4 As shown, Figure 4 The horizontal axis represents time, and the vertical axis represents the amplitude of the driving signal. Figure 4 The frequency of the first tooth side 22 includes two different frequencies; namely Figure 4 The driving signal shown in includes two frequency signals, T1 can represent a signal cycle of a signal of a first specified frequency, and T2 can represent a signal cycle of a signal of a second specified frequency. The signal cycle of the signal of the first specified frequency is different from the signal cycle of the signal of the second specified frequency, that is, the first specified frequency is different from the second specified frequency.

[0054] Driven by signals of different frequencies, the driving device 14 can drive the brush head 11 to vibrate at different frequencies, so that the oral cleaning device can clean the first tooth side surface 22 at different sweeping speeds, simulating the sweeping operation of the user manually cleaning the first tooth side surface 22, thereby improving the oral cleaning effect.

[0055] In the embodiment of this specification, the first designated frequency and the second designated frequency can be set according to actual needs. The first duration of the signal of the first designated frequency in a signal cycle and the second duration of the signal of the second designated frequency can also be set according to actual needs.

[0056] Specifically, based on the sweeping vibration oral cleaning device, the first specified frequency and the second specified frequency, the first duration and the second duration are specifically explained: the first specified frequency can be 270 Hz, and the second specified frequency can be 240 Hz; the signal of the first specified frequency can last for a first duration of 100 milliseconds in one signal cycle; the signal of the second specified frequency can last for a second duration of 40 milliseconds, and the signal of the first specified frequency and the signal of the second specified frequency alternate in sequence.

[0057] In practical applications, the frequencies of the first tooth side surfaces 22 may include other frequencies in addition to the first designated frequency and the second designated frequency, that is, the driving signal may include other frequencies in addition to the first designated frequency and the second designated frequency.

[0058] Similarly, the controller 13 can also be used to control the output drive signal for the second tooth side surface 23 to simulate the manual sweeping operation during tooth cleaning, thereby improving the cleaning effect.

[0059] Specifically, the controller 13 can be configured as follows: if the cleaning surface facing the brush wire area 111 is the second tooth side surface 23, determine a fourth duty cycle corresponding to the second tooth side surface 23 and multiple frequencies of the second tooth side surface 23 with different frequencies; output a driving signal with a duty cycle of the fourth duty cycle and a frequency of multiple frequencies of the second tooth side surface 23 alternating in sequence.

[0060] Optionally, the multiple frequencies of the second tooth side surface 23 with different frequencies may include at least a third specified frequency and a fourth specified frequency; within one cycle of the driving signal, the signal of the third specified frequency may last for a third time length, and the signal of the fourth specified frequency may last for a fourth time length.

[0061] In the embodiment of this specification, the fourth duty cycle can be the same as or different from the third duty cycle. The frequencies of the second tooth side faces 23 with multiple different frequencies can be completely different from the frequencies of the first tooth side faces 22 with multiple different frequencies, or they can be completely the same, or they can be partially the same, which is not specifically limited here.

[0062] The third duration may be the same as or different from the first duration. The fourth duration may be the same as or different from the second duration.

[0063] The third designated frequency and the fourth designated frequency can be set according to actual needs. In a signal cycle, the third duration of the signal of the third designated frequency can be continued, and the fourth duration of the signal of the fourth designated frequency can be continued can also be set according to actual needs.

[0064] Specifically, based on the sweeping vibration oral cleaning device, the third designated frequency and the fourth designated frequency, the third duration and the fourth duration are specifically explained: the third designated frequency can be 270 Hz, and the fourth designated frequency can be 240 Hz; the third duration that the signal of the third designated frequency can last within a signal cycle can be 100 milliseconds; the fourth duration that the signal of the fourth designated frequency can last can be 40 milliseconds.

[0065] In the embodiment of this specification, the fourth duty cycle can be 0.6. When cleaning the second tooth side surface 23, usually both the upper and lower teeth in the oral cavity are cleaned at the same time, and the cleaning surface is wider. Therefore, the fourth duty cycle is 0.6. Compared with the third duty cycle, the amplitude of the sweeping vibration oral cleaning device can be increased, thereby improving the cleaning effect of the second tooth side surface 23 and improving the cleaning efficiency.

[0066] In the embodiments of this specification, the driving signal may be a periodic signal, and one period of the driving signal includes signals of multiple frequencies, and the signals of multiple frequencies alternate in sequence. Driven by signals of different frequencies, the driving device 14 may drive the brush head 11 to vibrate at different frequencies. Specifically, the oral cleaning device may clean the second tooth side surface 23 at different sweeping speeds, simulating the sweeping operation of the user manually cleaning the second tooth side surface 23, thereby improving the oral cleaning effect.

[0067] In the embodiment of this specification, the operation mode of the oral cleaning device includes not only the recommended cleaning mode but also the autonomous cleaning mode. In the autonomous cleaning mode, the user can set the cleaning parameters according to his / her needs or preferences, so that the controller 13 can output the corresponding driving signal according to the cleaning parameters set by the user to drive the driving device 14 to drive the brush head 11 and the brush wire area 111 to perform the cleaning operation.

[0068] Optionally, the controller 13 may also be configured to: obtain user input data, where the user input data may be cleaning parameters set by the user for at least one of the cleaning surfaces; and generate a drive signal corresponding to the at least one of the cleaning surfaces based on the user input data.

[0069] In the embodiment of this specification, a button or touch unit for the user to input cleaning parameters may be provided in the oral cleaning device. The user can select the cleaning surface to be set, and then set the cleaning parameters for the selected cleaning surface. For the cleaning surface for which the user does not choose to set the cleaning parameters, the recommended cleaning mode can be used for cleaning.

[0070] It is understandable that the cleaning parameters input by the user may be different for different types of oral cleaning devices. For example, for a rotary oral cleaning device, the cleaning parameter input by the user may be the rotation speed of the brush head 11. For a sweeping vibration type or a high-frequency reciprocating vibration type oral cleaning device, the cleaning parameter input by the user may be the swing angle of the brush head 11 and the swing frequency of the brush head 11.

[0071] In order to ensure the cleaning effect and prevent damage to tooth enamel or gums, a corresponding value range can be set for the cleaning parameters of each cleaning surface. When the cleaning parameters input by the user exceed the corresponding value range, the information feedback device set on the oral cleaning device can be used to output the first prompt information. The first prompt information may include information for prompting the user that the cleaning parameters input by the user are too large or too small. In addition, the prompt information may also include information for prompting the user that the cleaning parameters input by the user may cause bad results.

[0072] The controller 13 can output a corresponding driving signal according to the cleaning parameters input by the user, so that the driving device 14 drives the brush wire area 111 through the brush head 11 to perform a cleaning operation according to the cleaning parameters input by the user, so that the user can clean the oral cavity according to his or her own needs.

[0073] In the embodiments of this specification, the operation mode of the oral cleaning device may also include a past history mode.

[0074] Specifically, the controller 13 may also be configured to: obtain user history data, where the user history data is cleaning parameters that the user has used in the past; and generate a drive signal corresponding to each of the cleaning surfaces based on the user history data.

[0075] In the embodiment of this specification, the user history data may be the cleaning parameters that the user has input and used for each cleaning surface in the past. After the controller 13 obtains the user history data of each cleaning surface, it may generate and output a driving signal corresponding to each cleaning surface based on the user history data of each cleaning surface, thereby avoiding the user from setting the cleaning parameters each time. Simplify the operation.

[0076] In actual applications, different cleaning operations are usually performed for different positions of the same cleaning surface to ensure the cleaning effect. For example, for the labial side surface 231 and the buccal side surface 232 in the second tooth side surface 23; when cleaning the labial side surface 231, the sweeping speed may be faster; but when sweeping the teeth from bottom to top or from top to bottom, the sweeping speed may change less. When cleaning the buccal side surface 232, the sweeping speed may be slower; but when sweeping the teeth from bottom to top or from top to bottom, the sweeping speed may change more. Therefore, the teeth in the oral cavity can also be divided into zones, and different powers are used to clean the cleaning surfaces in different areas.

[0077] Based on this, the controller 13 can be specifically configured to: determine the target cleaning surface that the brush wire area 111 is facing based on the posture of the oral cleaning device; determine the target oral region where the brush wire area 111 is located according to the motion state data.

[0078] A second preset duty cycle and a second preset frequency corresponding to the target cleaning surface at the target oral region are determined.

[0079] The output duty cycle is the second preset duty cycle, and the frequency is the driving signal of the second preset frequency.

[0080] In the embodiments of the present specification, the target cleaning surface may be the cleaning surface being cleaned by the brush wire area 111; the target oral area may be the oral area being cleaned by the brush wire area 111; the oral area may be a plurality of areas obtained by partitioning the teeth in the oral cavity, and the number of oral areas may be 4, 6, 8 or 12, which is not specifically limited herein.

[0081] Assuming that the number of oral regions is 12, the oral regions can include the upper left outer region, the upper left middle region, the upper left inner region, the upper right outer region, the upper right middle region, the upper right inner region, the lower left outer region, the lower left middle region, the lower left inner region, the lower right outer region, the lower right middle region, and the lower right inner region.

[0082] The driving signals corresponding to the same cleaning surface in different oral areas are not exactly the same; for example, the driving signal corresponding to the first tooth side surface 22 in the upper left outer area may be different from the driving signal corresponding to the first tooth side surface 22 in the upper left middle area; the driving signal corresponding to the first tooth side surface 22 in the upper left outer area may be the same as the driving signal corresponding to the first tooth side surface 22 in the upper right outer area.

[0083] The second preset duty cycle and the second preset frequency can be pre-determined parameters of a driving signal that has a better cleaning effect on the target cleaning surface in the target oral region. The driving device 14 is driven by a better driving signal to drive the brush area 111 to perform a cleaning operation, thereby improving the oral cleaning effect.

[0084] In practical applications, the second preset frequency can be a fixed frequency; in this case, the driving signal can be a signal containing only one frequency signal. The second preset frequency can also be a frequency of multiple different frequencies; in this case, the driving signal can be a signal containing multiple different frequency signals alternating in sequence.

[0085] When using an oral cleaning device, users are usually unable to determine whether the cleaning action is correct, and thus cannot guarantee the oral cleaning effect.

[0086] Based on this, the controller 13 can also be configured to: determine whether the angle between the brush wire area 111 and the cleaning surface facing the brush wire area 111 is within a preset angle range according to the posture of the oral cleaning device; if so, output prompt information indicating that the brushing method is correct.

[0087] In the embodiment of the present specification, when the angle between the brush wire area 111 and the cleaning surface to which the brush wire area 111 is facing is within the preset angle range, it can be indicated that the cleaning angle of the oral cleaning device is relatively appropriate, and the information feedback device can be used to output the second prompt information. The second prompt information can be used to prompt the user to brush teeth in the correct way, so as to assist the user to be familiar with and master the correct way of brushing teeth, thereby facilitating the user to subsequently clean teeth in the correct way of brushing teeth.

[0088] Optionally, when the angle between the brush wire area 111 and the cleaning surface to which the brush wire area 111 is facing is not within the preset angle range, it can indicate that the cleaning angle of the oral cleaning device is not appropriate, and the information feedback device can be used to output a third prompt message, which can be used to prompt the user that the brushing method is incorrect. Of course, in order to avoid disturbing the user and causing trouble to the user, the third prompt message can also be not output.

[0089] In the embodiments of this specification, the preset angle range may be 45°-15°~45°+15°.

[0090] In actual applications, the user may press too hard during brushing, resulting in excessive pressure on the cleaning surface in contact with the brush wire area 111, which may cause damage to the tooth enamel.

[0091] Based on this, the sensor element 12 in the oral cleaning device may further include a pressure detection unit for performing pressure detection.

[0092] The controller 13 may also be configured to: obtain a cleaning pressure value collected by the pressure detection unit; determine whether the oral cleaning operation is too stressful based on the cleaning pressure value and a preset pressure value; and if so, send a third prompt message to the information feedback device.

[0093] In the embodiment of this specification, during the operation of the oral cleaning device, the pressure detection unit can detect the cleaning pressure value of the user during the brushing process according to the preset frequency, and send the collected cleaning pressure value to the controller 13. The controller 13 can compare the obtained cleaning pressure value with the preset pressure value to determine whether the user's brushing force is too high. If so, the information feedback device can be used to display a prompt message to prompt the user to reduce the cleaning force.

[0094] The display form of the prompt information can be visual, such as flashing of the prompt light. It can also be voice: for example, it can be a prompt voice output such as "Please reduce the cleaning force to avoid damaging the tooth enamel." It can also be a tactile prompt, such as vibration for a predetermined period of time.

[0095] The preset pressure values ​​of different cleaning surfaces may be the same or different. For example, corresponding preset pressure values ​​may be set for the occlusal surface 21, the first tooth side surface 22, and the second tooth side surface 23, respectively.

[0096] In addition, for the same cleaning surface, the preset pressure values ​​of the same cleaning surface at different oral locations may be the same or different.

[0097] In the embodiments of the present specification, in order to facilitate the user to understand the oral cleaning effect of this time, the oral cleaning effect information of this time can also be displayed to the user.

[0098] Optionally, the oral cleaning device may further include an information feedback device and a timer.

[0099] The timer may be configured to: measure the cleaning time of the oral cleaning device to obtain the measured time.

[0100] The controller 13 can also be configured to: determine the oral area information where the brush wire area 111 is located according to the motion state data; the oral area information is used to reflect the oral area that the brush wire area 111 is cleaning; based on the timing duration of the timer and the oral area information, count the actual cleaning time corresponding to each of the oral areas and the power of the cleaning operation; based on the actual cleaning time corresponding to each of the oral areas and the power of the cleaning operation, determine the cleaning effect information of each of the oral areas; send the cleaning effect information of each of the oral areas to the information feedback device.

[0101] The information feedback device may be configured to: receive the cleaning effect information sent by the controller 13; and display the cleaning effect information.

[0102] Optionally, the information feedback device may include at least one of a visual module, an auditory module and a tactile module.

[0103] In the embodiments of the present specification, based on the position information determination method in the prior art, the motion state data of the oral cleaning device can be used to determine the oral area information of the brush head 11, thereby determining the oral area that the oral cleaning device is cleaning, and then determining the actual cleaning time of each oral area according to the timing duration of the timer.

[0104] In practical applications, statistics can be collected for the actual cleaning time of each oral region, the power of the cleaning operation, and the pressure value of the user during brushing, and the above statistical contents can be sent to the information feedback device. The above information is displayed through the information feedback device.

[0105] In the embodiments of the present specification, during the oral cleaning process, the user may only pass through a certain oral area when moving the oral cleaning device, but not clean the oral area. In order to avoid recording the time when the user passes through a certain oral area when moving the oral cleaning device as the actual cleaning time for the oral area, the actual cleaning time of the oral area obtained by statistics may be inaccurate.

[0106] In the embodiment of this specification, the controller 13 can also be used for: After determining the oral region information cleaned by the oral cleaning device according to the motion state data, it is determined whether the time duration for which the oral cleaning device is located in the oral region corresponding to the oral region information is greater than a specified time duration to obtain a first determination result.

[0107] If the first judgment result indicates that the time length that the oral cleaning device is located in the oral region corresponding to the above-mentioned oral region information is greater than the specified time length, the time length that the oral cleaning device is located in the oral region corresponding to the above-mentioned oral region information is determined to be the effective cleaning time length.

[0108] It can be understood that based on the timing duration of the timer and the oral area information, the actual cleaning duration corresponding to each oral area is counted, which may be the effective cleaning duration corresponding to each oral area.

[0109] In the embodiments of this specification, when the oral cleaning device stays in a certain oral area for a specified time, it can be determined that the electric toothbrush has not only passed through the oral area during the movement, but has performed an effective cleaning operation on the oral area. Therefore, the above process can effectively improve the accuracy and reliability of the actual cleaning time of each oral area obtained by statistics.

[0110] In order to further improve the user's cleaning effect, when the timer reaches the preset cleaning time, the user can also perform a re-brushing operation for the oral area where the actual cleaning time does not reach the recommended cleaning time.

[0111] Optionally, before sending the cleaning effect information of each of the oral areas to the information feedback device, the controller 13 can also be configured to: determine the oral area to be re-brushed based on the actual cleaning time corresponding to each of the oral areas and the recommended cleaning time corresponding to each of the oral areas; and determine whether the user confirms the re-brushing operation based on the motion state data.

[0112] The sending of the cleaning effect information of each oral region to the information feedback device may specifically include: If it is determined that the user confirms not to perform the re-brushing operation, the cleaning effect information of each oral area is sent to the information feedback device.

[0113] In the embodiment of the present specification, the predetermined cleaning time may be the duration of a pre-set toothbrushing cycle, and the predetermined cleaning time may be 2 minutes. The recommended cleaning time may be the cleaning time pre-set for each oral region.

[0114] After the controller 13 determines the oral area to be re-brushed that needs to be re-brushed, it can also determine the re-brushing time of each oral area to be re-brushed according to the actual cleaning time corresponding to each oral area and the recommended cleaning time corresponding to each oral area. The information of the oral area to be re-brushed and the re-brushing time of each oral area to be re-brushed are fed back to the user through the information feedback device; so that the user can clearly know the oral area to be re-brushed and the corresponding re-brushing time, and then it is convenient for the user to decide whether to re-brush.

[0115] In the embodiments of the present specification, the posture of the oral cleaning device can be determined based on the motion state data of the oral cleaning device collected by the sensor element 12, and it can be judged whether the user is performing a re-brushing operation based on the posture of the oral cleaning device. Usually, there is a difference between the posture of the oral cleaning device when the user performs a brushing operation and the posture of the oral cleaning operation when the user does not perform a brushing operation; for example, the inclination angle of the oral cleaning device when performing a brushing operation is usually within a preset angle range and is usually not vertical. When the oral cleaning device is not performing a cleaning operation, it may be placed vertically on the bathroom countertop. At this time, the angle of the oral cleaning device is different from the angle when performing a brushing operation. Therefore, it can be determined whether the user is performing a re-brushing operation based on the posture of the oral cleaning device.

[0116] In the embodiment of the present specification, whether the user needs to brush his teeth again can be determined by determining whether the user has performed the brushing operation within a preset time period.

[0117] If the user does not perform the tooth brushing operation within a preset time period, it can be determined that the user does not perform a supplementary brushing operation, and the cleaning effect information of each of the oral regions can be sent to the information feedback device.

[0118] If the user performs the tooth brushing operation within the preset time, it can be determined that the user performs a re-brushing operation. After the re-brushing operation is completed, the cleaning effect information of the oral area can be re-counted and the re-counted cleaning effect information can be sent to the information feedback device.

[0119] For ease of understanding, the present specification also provides a specific process for determining the posture of the oral cleaning device according to the motion state data of the oral cleaning device: Figure 5 This is a flow chart of determining the posture of an oral cleaning device provided in an embodiment of this specification. Figure 5 To further illustrate the specific scheme of the embodiments of this specification.

[0120] Step 502: Obtain raw acceleration data.

[0121] The raw acceleration data may be collected using an accelerometer, and the accelerometer may collect acceleration data of the oral cleaning device at a preset frequency. The accelerometer may be a three-axis accelerometer. The raw acceleration data may include acceleration data in three directions: the X-axis, the Y-axis, and the Z-axis.

[0122] Step 504: Filter the original acceleration data to obtain target acceleration data.

[0123] In the embodiments of this specification, a low-pass filter may be used to filter the original acceleration data to filter out high-frequency data generated by the vibration of the driving device, thereby reducing data anomalies.

[0124] Step 506: Calculate the average value of the target acceleration data within the preset time period to obtain the acceleration mean.

[0125] In the embodiments of this specification, the preset time period can be set according to actual needs and is not specifically limited here.

[0126] The target acceleration data within the preset time period is averaged, and the original acceleration data in each direction is averaged, so as to obtain the acceleration mean in each direction.

[0127] Step 508: Determine the angle value of the oral cleaning device according to the acceleration mean value.

[0128] The angle of the oral cleaning device relative to gravity can be calculated based on the average acceleration using methods in the prior art, and the detailed calculation process will not be repeated here.

[0129] Figure 6 This is a flow chart of determining the posture of an oral cleaning device provided in an embodiment of this specification. Figure 6 To further illustrate the specific scheme of the embodiments of this specification.

[0130] Step 602: Obtain raw gyroscope data.

[0131] In the embodiments of this specification, the original gyroscope data may be angular velocity data of the X-axis, Y-axis, and Z-axis collected by the gyroscope.

[0132] Step 604: Filter the original gyroscope data to obtain target gyroscope data.

[0133] In practical applications, a low-pass filter can be used to filter the raw gyroscope data to filter high-frequency data generated by the vibration of the driving device, thereby reducing data anomalies.

[0134] Step 606: Calculate quaternion based on target gyroscope data.

[0135] In the embodiments of this specification, the Runge-Kutta method may be used to calculate the standard quaternion based on the target gyroscope data.

[0136] Step 608: Normalize the quaternion to obtain a normalized quaternion.

[0137] Step 610: Determine the posture of the oral cleaning device according to the normalized quaternion.

[0138] In the embodiments of the present specification, the normalized quaternion can be converted into the Euler angles of the oral cleaning device, namely, the yaw angle, pitch angle and roll angle of the oral cleaning device, so as to obtain the posture of the oral cleaning device.

[0139] In the embodiments of the present specification, in order to avoid inaccurate posture determination of the oral cleaning device using single raw acceleration data and raw gyroscope data, the posture of the oral cleaning device can also be determined by combining the raw acceleration data and the raw gyroscope data to improve the accuracy of the determined posture of the oral cleaning device.
