[0034] Figure 1A is an application scenario diagram of an electric toothbrush control method according to an embodiment. As shown in Figure 1A , the electric toothbrush control method disclosed in the embodiment of the present application can be applied to an electric toothbrush 100 , which may include a brush head 110 and a brush handle 120 , with the brush head 110 and the brush handle 120 being detachably connected.

[0035] In some embodiments, the electric toothbrush 100 may further include a position detection device, which may include, but is not limited to, one or more of a posture sensor, a camera, a motion sensor, a pressure sensor, a photoelectric sensor, etc. The position detection device may be used to detect the oral position information of the brush head 110 of the electric toothbrush 100 in the oral cavity. The electric toothbrush 100 may identify the oral region where the brush head 110 of the electric toothbrush 100 is located in the oral cavity based on the information collected by the position detection device.

[0036] In the embodiment of the present application, the electric toothbrush 100 can identify a first oral region in which the brush head 110 is located, and based on multiple sets of operating parameters corresponding to the first oral region, control the brush head 110 of the electric toothbrush 100 to perform a combination of multiple motions according to the multiple sets of operating parameters. The multiple sets of operating parameters can correspond one to one with the multiple motions, and the combination of multiple motions can include performing a combination of motions in multiple time periods, and / or performing a combination of multiple motions in the same time period.

[0037] In some embodiments, the handle 120 may be provided with a motor. When the electric toothbrush 100 is in operation, the motor may be in an operating state. The electric toothbrush 100 may control the motor to move, thereby driving the brush head 110 to move, thereby performing an oral cleaning operation to achieve an oral cleaning effect. The electric toothbrush 100 may control the motor to perform a combination of multiple motions according to multiple sets of operating parameters corresponding to the first oral region. The motor's motion pattern may match the motion pattern of the brush head 110.

[0038] Taking the superimposed motion of small-amplitude vibration and large-amplitude sweeping of the brush head 110 of the electric toothbrush 100 as an example, the electric toothbrush 100 can control the rotor in the motor to swing back and forth with the reference position as the reference zero axis, and control the rotor to rotate to change the reference position, wherein the rotor in the motor swings back and forth with the reference position as the reference zero axis, thereby driving the brush head 110 to vibrate with a smaller amplitude, and the rotation of the rotor to change the reference position can drive the brush head 110 to sweep with a larger amplitude.

[0039] For example, Figure 1B is a schematic diagram of the motor structure in one embodiment. As shown in Figure 1B, the motor may include a rotor 130, a stator module 140, and a control module 150. The rotor 130 includes a central axis 131, which is detachably connected to the brush head 110. The stator module 140 and the rotor 130 can magnetically cooperate to drive the rotor 130 to rotate. The stator module 140 may include a permanent magnet or an electromagnet.

[0040] The control module 150 can control the rotor 130 to reciprocate in the circumferential direction. In some embodiments, the control module 150 can control the rotor 130 to oscillate back and forth with respect to a reference position as the zero axis, and control the rotor 130 to rotate to change the reference position, thereby increasing the circumferential swing amplitude of the rotor 130. Furthermore, the control module 150 can control the central axis 131 to oscillate back and forth with respect to the reference position as the zero axis, and control the central axis 131 to rotate to change the reference position. During the movement of the central axis 131, it can drive the brush head 110 to move, thereby achieving an oral cleaning operation.

[0041] The control module 150 may include a position detection element 151 and a controller 152. The position detection element 151 may be used to detect the real-time position of the rotor 130, and the controller 152 may control the movement of the rotor based on the real-time position of the rotor 130. The position detection element 151 may include, but is not limited to, a Hall effect element, an optical element, or other element having a position detection function.

[0042] It should be noted that the motor may also include other components, such as copper cores, coils, bearings, etc. The embodiments of the present application do not limit the specific structure of the motor.

[0043] It should be noted that Figure 1B only shows a motor structure of the electric toothbrush 100 that can control the brush head 110 to perform a superimposed motion of small-amplitude vibration and large-amplitude sweeping. The motor can also be a motor structure that can realize other motion modes. The embodiment of the present application does not limit the specific structure of the motor.

[0044] As shown in FIG2 , in one embodiment, a method for controlling an electric toothbrush is provided. The method can be applied to the above-mentioned electric toothbrush, and the method includes the following steps:

[0045] Step 210: Identify a first oral region where the electric toothbrush is located in the oral cavity.

[0046] The user's mouth can be divided into multiple oral areas. In some embodiments, the multiple oral areas may include tooth areas and / or tooth surfaces, wherein the tooth areas may include but are not limited to the incisor area, the lateral tooth area, the posterior tooth area, etc., and the tooth surfaces may include the occlusal surface, the tooth side surface, etc. Further, the tooth side surface may also include the outer side surface of the tooth and the inner side surface of the tooth.

[0047] For example, FIG3A is a schematic diagram of the division of a user's teeth in one embodiment. As shown in FIG3A , the user's teeth can be divided into 10 tooth regions, which may include two posterior tooth regions, two lateral tooth regions, and one incisor region in the upper half of the teeth, and two posterior tooth regions, two lateral tooth regions, and one incisor region in the lower half of the teeth. By separately dividing a transition zone (i.e., the lateral tooth region) between the molars and incisors, a more detailed division of the tooth regions in the oral cavity can be achieved. The precision of the tooth region division can make the brushing operation performed by the electric toothbrush more suitable for each tooth region.

[0048] For example, Figure 3B is a schematic diagram of tooth surfaces in one embodiment. As shown in Figure 3B , the occlusal surface 310 of a tooth is the surface on which the tooth bites, and the tooth side surfaces may include the outer surface 330 and the inner surface 320 of the tooth. The outer surface 330 of the tooth is closest to the lips, and the inner surface 320 of the tooth is closest to the tongue.

[0049] During the operation of the electric toothbrush, the electric toothbrush can identify the first oral area in the oral cavity, and further, the electric toothbrush can identify the first oral area where the brush head is located in the oral cavity. The operation process may refer to the process of a user brushing their teeth with the electric toothbrush.

[0050] In some embodiments, the electric toothbrush may include a position detection device, which includes one or more of a posture sensor, a camera, a motion sensor, a pressure sensor, a photoelectric sensor, etc. The electric toothbrush can use the position detection device to identify the first oral region where the electric toothbrush is located in the oral cavity.

[0051] The position detection device can be used to detect the oral position information of the electric toothbrush brush head in the oral cavity. The oral position information can be the specific position of the brush head in the oral cavity, such as the specific tooth located in the oral cavity, a tooth surface of a specific tooth located in the oral cavity, and the like. Optionally, the oral position information can also be the oral region where the brush head is located in the oral cavity. The electric toothbrush can determine the oral position information of the brush head in the oral cavity based on the information collected by the position detection device, thereby obtaining the first oral region where the electric toothbrush is located in the oral cavity.

[0052] Taking the position detection device as a camera device as an example, the camera device can be set on the brush handle or brush head of the electric toothbrush. The camera device can capture images containing the user's face and / or mouth. The electric toothbrush can recognize the image captured by the camera device, extract image features of the image captured by the camera device, and determine the first oral area where the electric toothbrush is located in the mouth based on the image features.

[0053] Taking the position detection device as an attitude sensor as an example, the attitude sensor may include but is not limited to IMU (Inertial Measurement Unit), gyroscope, gravity sensor, etc. The attitude information of the electric toothbrush can be collected by the attitude sensor, and the electric toothbrush can determine the first oral area where the electric toothbrush is located in the oral cavity based on the attitude information collected by the attitude sensor. Optionally, standard attitude information corresponding to each oral area can be pre-constructed, and by comparing the attitude information collected by the attitude sensor with the standard attitude information corresponding to each oral area, the standard attitude information with the highest similarity to the attitude information collected by the attitude sensor is determined, and the oral area corresponding to the standard attitude information with the highest similarity is determined as the first oral area where the electric toothbrush is located in the oral cavity.

[0054] Taking the example of a position detection device including a motion sensor and a pressure sensor, or a position detection device including a motion sensor and a photoelectric sensor, the electric toothbrush can collect the pressure value of the brush head through the pressure sensor, or collect the light signal corresponding to the brush head through the photoelectric sensor, and can detect whether the brush head has entered the oral cavity based on the pressure value collected by the pressure sensor or the light signal collected by the photoelectric sensor. After detecting that the brush head has entered the oral cavity, the motion sensor can collect motion information of the electric toothbrush, which may include but is not limited to the motion direction and speed, and the first oral region where the electric toothbrush is located can be determined based on the motion information collected by the motion sensor.

[0055] It should be noted that other methods may be used to identify the first oral area where the electric toothbrush is located in the oral cavity, and are not limited to the methods described above.

[0056] In an embodiment of the present application, the electric toothbrush can accurately identify the first oral area where the electric toothbrush is located in the oral cavity through the position detection device, thereby improving the accuracy of subsequent control of the electric toothbrush.

[0057] Step 220 , based on the multiple sets of operating parameters corresponding to the first oral region, controlling the electric toothbrush to perform a combination of multiple motions according to the multiple sets of operating parameters.

[0058] An electric toothbrush can support a variety of different motion modes, which can be the motion mode of the brush head when the electric toothbrush is performing a cleaning operation on the oral cavity. For each oral area in the oral cavity, multiple sets of operating parameters corresponding to each oral area can be pre-configured. A set of operating parameters can correspond to a motion mode, and a set of operating parameters can be used to drive the electric toothbrush to perform the corresponding motion. In some embodiments, the multiple sets of operating parameters corresponding to different oral areas can be different or the same. For example, different oral areas can correspond to different motion modes, or different oral areas can correspond to the same motion mode, but the specific parameter values ​​of the operating parameters driving the motion are different.

[0059] It should be noted that the multiple sets of operating parameters corresponding to each oral area can be configured by the user according to his or her actual needs, or can be configured by the manufacturer of the electric toothbrush, which is not limited here.

[0060] Each set of operating parameters may include at least one motion parameter and / or at least one electrical parameter. Optionally, the motion parameter may include, but is not limited to, one or more of motion amplitude, motion frequency, motion intensity, motion timing, motion duration, etc.

[0061] The target motion corresponds to an amplitude that refers to the range of motion of the brush head during the target motion, which can be expressed in terms of distance, angle, etc. The target motion can refer to the number of times the brush head performs the target motion per unit time. The target motion can refer to the number of times the brush head performs the target motion per unit time. The target motion can refer to the sequence of the target motion among multiple motions. The target motion can refer to the duration of time the brush head performs the target motion. The target motion can refer to any motion supported by the electric toothbrush.

[0062] Since the movement of an electric toothbrush is generated by the movement of its motor, the operating parameters may also include electrical parameters corresponding to the motor. Optionally, the electrical parameters include a duty cycle, which may refer to the percentage of time the motor is powered on within a cycle. Optionally, the duty cycle corresponding to the target movement may be associated with the movement force generated by the target movement. The higher the duty cycle corresponding to the target movement, the greater the movement force generated by the target movement. It should be noted that the electrical parameters may also include other parameters, such as the operating voltage and operating current of the motor.

[0063] During operation, the electric toothbrush can identify a first oral region in the oral cavity, obtain multiple sets of operating parameters corresponding to the first oral region, and control the electric toothbrush to perform a combination of multiple motions according to the multiple sets of operating parameters to perform a brushing operation on the first oral region. The multiple sets of operating parameters can correspond one-to-one to the multiple motions.

[0064] The combination of multiple sports may include performing a combination of one type of sports in multiple time periods, and / or performing a combination of multiple sports in the same time period.

[0065] As an embodiment, the electric toothbrush performs a combination of multiple motions according to multiple sets of operating parameters, which can be a combination of performing one motion in multiple time periods. Furthermore, the oral cleaning time corresponding to the first oral area is the target time, and the target time can be divided into multiple time periods, and the length of each time period can be the same or different. In each time period, the electric toothbrush can perform one motion, different motions can be performed in different time periods, or the motions performed in different time periods are the same, but the corresponding operating parameters are different. For example, the oral cleaning time corresponding to the first oral area is 30 seconds, which can be divided into 3 time periods, each time period is 10 seconds, then the electric toothbrush can perform motion A in the first time period, motion B in the first time period, and motion C in the third time period; or, the electric toothbrush can perform motion A in the first time period, motion B in the first time period, and motion B in the third time period, but the motion amplitude of motion B performed in the first time period is smaller than the motion amplitude of motion B performed in the third time period.

[0066] As another embodiment, the electric toothbrush performs a combination of multiple motions according to multiple sets of operating parameters, which may be a combination of multiple motions performed in the same time period. The combination of multiple motions performed in the same time period may mean that the electric toothbrush performs multiple different motions simultaneously in the same time period. For example, motion A and motion B may be performed simultaneously during the oral cleaning time corresponding to the first oral area.

[0067] In some embodiments, the various movements performed by the electric toothbrush may include loosening movement and stripping movement, and the operating parameters corresponding to the loosening movement include at least the cleaning force, and the operating parameters corresponding to the stripping movement include at least the cleaning range; wherein, the loosening movement is used to loosen the dental plaque, and the stripping movement is used to strip the dental plaque off the tooth surface; at least one of the loosening movement and the stripping movement corresponding to different oral areas is different.

[0068] In some embodiments, the frequency of the loosening motion is higher than the frequency of the stripping motion, and the amplitude of the loosening motion is smaller than the amplitude of the stripping motion. By combining the loosening motion and the stripping motion, the loosening motion can loosen the plaque, and the stripping motion can remove the plaque from the tooth surface, thereby achieving a better cleaning effect. Furthermore, corresponding loosening and stripping motions can be configured for different oral regions, thereby improving the adaptability of the cleaning operation of the electric toothbrush to different oral regions.

[0069] In some embodiments, the various motions performed by the electric toothbrush may include, but are not limited to: reciprocating oscillation of the brush head at a first angle along the length of the handle, reciprocating oscillation of the brush head at a second angle along the length of the handle, reciprocating linear motion of the brush head along the length of the handle, rotation of the bristles of the brush head on a plane, reciprocating linear motion of the brush head perpendicular to the length of the handle, etc. The first angle may be smaller than the second angle.

[0070] The brush head swings back and forth at a first angle along the length of the brush handle, which can be understood as the brush head vibrating with a smaller amplitude along the length of the brush handle. The brush head swings back and forth at a second angle along the length of the brush handle, which can be understood as the brush head sweeping with a larger amplitude along the length of the brush handle. The brush head performs reciprocating linear motion along the length of the brush handle, which can be understood as the brush head performing telescopic motion along the length of the brush handle. The rotation of the bristles of the brush head on a plane can refer to the rotational motion of the bristles on the same plane. The brush head performs reciprocating linear motion along a length perpendicular to the brush handle, which can be understood as the brush head performing a tapping or knocking motion along the length perpendicular to the brush handle.

[0071] In some embodiments, the electric toothbrush can perform a combination of a first motion and a second motion, that is, the electric toothbrush can perform a combination of two different motions, wherein the first motion can be the brush head swinging back and forth at a first angle around the length direction of the brush handle, and the second motion can be any one of the following: the brush head swinging back and forth at a second angle around the length direction of the brush handle, the brush head performing reciprocating linear motion along the length direction of the brush handle, the bristles of the brush head rotating on a plane, and the brush head performing reciprocating linear motion in a direction perpendicular to the length direction of the brush handle. By combining a smaller amplitude vibration of the brush head with other motions, the vibration can peel off the plaque from the tooth surface, and the second motion can scrape off the plaque, thereby achieving a better cleaning effect.

[0072] In some embodiments, after the electric toothbrush identifies the first oral area where the brush head is located, it can also determine the target motion combination corresponding to the first oral area, obtain the operating parameters corresponding to the various motions contained in the target motion combination in the first oral area, obtain multiple sets of operating parameters corresponding to the first oral area, and control the electric toothbrush to perform a combination of multiple motions according to the multiple sets of operating parameters.

[0073] Corresponding motion combinations can be configured for each of the multiple oral areas. The motion combinations corresponding to the oral areas can be used to characterize the specific motion mode of the combined motion of the multiple motions corresponding to the oral area. A motion combination can include multiple motions and a combination of the multiple motions. The combination mode can be a combination mode of performing one motion in multiple time periods and / or a combination mode of performing multiple motions in the same time period. The corresponding motion combination can be configured for each oral area, so that the combined motion of the multiple motions performed by the electric toothbrush can be more adapted to the needs of each oral area, thereby improving the cleaning effect and intelligence of the electric toothbrush.

[0074] In an embodiment of the present application, the electric toothbrush can perform a combination of multiple motions, which can improve the cleaning effect of the electric toothbrush compared to a single motion mode, and can have corresponding multiple sets of operating parameters for different oral areas. The setting method of the operating parameters is more diversified and can adapt to the cleaning needs of different oral areas. The cleaning operation of the electric toothbrush is improved from multiple cleaning dimensions. The adaptability of the electric toothbrush to different oral areas is improved, thereby improving the intelligence of the electric toothbrush.

[0075] As shown in FIG4 , in another embodiment, a method for controlling an electric toothbrush is provided. The method can be applied to the above-mentioned electric toothbrush, and the method includes the following steps:

[0076] Step 402: Identify a first oral region where the electric toothbrush is located in the oral cavity.

[0077] The description of step 402 may refer to the relevant description of step 210 in the above embodiment, and will not be repeated here.

[0078] Step 404: Determine multiple groups of operating parameters corresponding to the first oral region and the target brushing mode according to the target brushing mode currently being run by the electric toothbrush.

[0079] An electric toothbrush can support multiple brushing modes, and the cleaning effects achieved by different brushing modes may be different. For example, an electric toothbrush can support a gentle cleaning mode, a daily cleaning mode, and an enhanced cleaning mode. Among them, the cleaning ability of the gentle cleaning mode may be less than the cleaning ability of the daily cleaning mode, and the cleaning ability of the daily cleaning mode may be less than the cleaning ability of the enhanced cleaning mode; the gentle cleaning mode may provide greater oral care than the daily cleaning mode, and the daily cleaning mode may provide greater oral care than the enhanced cleaning mode. Optionally, the cleaning ability can be characterized by one or more indicators such as the speed at which the electric toothbrush removes plaque in the oral cavity, the rate of plaque residue after the electric toothbrush completes the brushing operation, and the amount of plaque removed by the electric toothbrush per unit time. The degree of care can refer to the degree of protection provided to the oral cavity. Optionally, the degree of care can be characterized by the force and amplitude of the movement generated by the electric toothbrush during the brushing operation, and the damage to the teeth and / or gums (such as tooth surface wear, gum bleeding, etc.) after the electric toothbrush completes the brushing operation.

[0080] For each oral area in the mouth, multiple sets of operating parameters corresponding to each brushing mode can be configured in multiple brushing modes. The multiple sets of operating parameters corresponding to the same oral area in different brushing modes may be the same or different. After the electric toothbrush determines the first oral area where the brush head is located in the mouth, it can determine the multiple sets of operating parameters corresponding to the first oral area and the target brushing mode based on the target brushing mode currently being run by the electric toothbrush. The target brushing mode can be any brushing mode supported by the electric toothbrush.

[0081] The target brushing mode can be a brushing mode selected by the user according to his or her own needs before the electric toothbrush performs a brushing operation, or it can be a brushing mode that the electric toothbrush runs by default, or a brushing mode that the electric toothbrush recommends to run based on the user's oral condition (such as cleaning condition, health condition, etc.). In some embodiments, the electric toothbrush can respond to a start-up work instruction and run the target brushing mode. The start-up work instruction may refer to an instruction for triggering the electric toothbrush to start working, and further, the start-up work instruction may refer to an instruction for triggering the electric toothbrush to start a brushing operation. In some embodiments, when the electric toothbrush detects a start-up work operation, a start-up work instruction may be generated. The start-up work operation may include but is not limited to one or more operations on the touch parts (such as buttons, touch panels, etc.) on the electric toothbrush, gesture operations, operations that change the posture of the electric toothbrush, etc.

[0082] When the electric toothbrush runs the target brushing mode to brush the oral cavity, the electric toothbrush can identify the first oral area where the brush head is located in the oral cavity and obtain multiple sets of operating parameters corresponding to the first oral area and the target brushing mode.

[0083] Step 406 , based on the multiple sets of operating parameters corresponding to the first oral area and the target brushing mode, control the electric toothbrush to perform a combination of multiple motions according to the multiple sets of operating parameters.

[0084] The electric toothbrush can control the electric toothbrush to perform a combination of multiple movements according to multiple sets of operating parameters corresponding to the first oral area and the target brushing mode, so as to perform a brushing operation on the first oral area that is adapted to the target brushing mode.

[0085] In an embodiment of the present application, the electric toothbrush can support multiple brushing modes. For each oral area in the mouth, multiple sets of operating parameters corresponding to each brushing mode can be configured, further diversifying the setting method of the operating parameters, adapting to the different cleaning needs of users, improving the cleaning effect of the electric toothbrush, and improving the user experience.

[0086] In some embodiments, the multiple sets of operating parameters corresponding to the first oral area may include a first set of operating parameters and a second set of operating parameters, and the multiple movements performed by the electric toothbrush according to the multiple sets of operating parameters may include a first movement corresponding to the first set of operating parameters and a second movement corresponding to the second set of operating parameters.

[0087] In a specific embodiment, the electric toothbrush may include a motor, wherein the first motion may include the motor's rotor oscillating back and forth about a reference position as a zero axis, and the second motion may include the rotor rotating to change the reference position. The rotor oscillates back and forth circumferentially about the reference position as a zero axis, wherein the oscillation primarily refers to the reciprocating motion of the rotor in a circumferential direction about the reference zero axis, and the rotation adjusts the reference position of the rotor's reciprocating oscillation.

[0088] For example, FIG5A is a schematic diagram illustrating a rotor oscillating back and forth with a reference position as the zero axis in accordance with one embodiment. As shown in FIG5A , if the rotor oscillates back and forth with zero position 510 as the zero axis, the range covered during the oscillation is oscillation range 520, and the rotor position fluctuates between position 522 and position 524. The rotor oscillates back and forth with zero position 510 as the zero axis, which can be understood as the rotor oscillating clockwise around the zero axis with zero position 510 as the zero axis to position 524, then oscillating counterclockwise from position 524 to position 522, and then oscillating clockwise from position 522 to zero position 510. This process can be considered one oscillation cycle. The rotor can oscillate back and forth multiple times within one oscillation cycle, and the reference position remains unchanged within one oscillation cycle. Among them, the zero position 510 may refer to the default initial position of the rotor. Generally speaking, when the rotor in the motor is at the zero position 510, the side of the brush head with bristles is in the center of the front, corresponding to the front of the handle, so as to facilitate the user to use the electric toothbrush.

[0089] For example, FIG5B is a schematic diagram illustrating how the reference position of the rotor changes in one embodiment. As shown in FIG5B , the rotor can be controlled to rotate to switch the reference position from zero position 510 to position 530. The rotor can then oscillate back and forth with position 530 as the reference zero axis. The range covered by this oscillation is a oscillation range 540, and the rotor position changes back and forth between positions 542 and 544. For example, the rotor can oscillate from position 530 to position 542, then from position 542 to position 544, and then from position 544 to position 530, and so on multiple times.

[0090] The rotor of the motor swings back and forth with the reference position as the zero axis, which can drive the brush head of the electric toothbrush to vibrate slightly (such as the slight vibration corresponding to the swing range 520 in FIG. 5A or the swing range 540 in FIG. 5B ); the rotor of the motor rotates to change the reference position, which can drive the brush head of the electric toothbrush to sweep widely (such as the sweeping range from position 550 to position 560 in FIG. 5B ), thereby realizing the superimposed motion of slight vibration and slight sweeping of the brush head, which can effectively clean the oral cavity and improve the cleaning effect of the electric toothbrush.

[0091] The first motion corresponds to a first set of operating parameters, which may include one or more swing parameters. Optionally, the first set of operating parameters may include one or more parameters such as a swing frequency, a first duty cycle, and a swing amplitude corresponding to the first motion. The swing frequency may refer to the number of times the rotor swings back and forth within one swing cycle; the first duty cycle may refer to the duty cycle input to the rotor to drive the rotor to swing back and forth; the swing amplitude may refer to the range corresponding to a single reciprocating swing of the rotor in the circumferential direction. The swing amplitude may be an angle value or a distance value. Taking Figure 5A as an example, the swing amplitude may refer to the angle between position 522 and position 524, or it may be the straight-line distance moved by the brush head when the rotor swings back and forth according to the swing interval 520.

[0092] The second motion corresponds to a second set of operating parameters, which may include one or more rotation parameters. Optionally, the second set of operating parameters may include one or more parameters corresponding to the second motion, including a rotation frequency, a second duty cycle, and a rotation range. The rotation frequency may refer to the number of times the rotor switches between reference positions per unit time, the second duty cycle may refer to the duty cycle input to the rotor to drive the rotor to rotate and change the reference position, and the rotation range may refer to the range of rotor rotation, which can also be understood as the range of rotor motion. For example, in FIG5B , the rotation range may be between positions 550 and 560. Optionally, the rotation range may be defined using a zero position as a reference and a deflection angle relative to the zero position. For example, if the zero position corresponds to 0 degrees, the rotation range may be -10 degrees to 10 degrees. Thus, the rotor may rotate circumferentially between a position 10 degrees counterclockwise relative to the zero position and a position 10 degrees clockwise relative to the zero position.

[0093] In some embodiments, corresponding first and second sets of operating parameters can be set for multiple oral areas in the mouth, that is, corresponding swing parameters and rotation parameters can be set for multiple oral areas, so that the superimposed motion of vibration and sweeping performed by the electric toothbrush can better adapt to each oral area.

[0094] In some embodiments, the first oral region may include a first tooth surface; the first tooth surface may be an occlusal surface or a tooth flank surface. The oscillation frequency corresponding to the occlusal surface is greater than the oscillation frequency corresponding to the tooth flank surface; and / or the rotation range corresponding to the occlusal surface is smaller than the rotation range corresponding to the tooth flank surface; and / or the first duty cycle corresponding to the occlusal surface is greater than the first duty cycle corresponding to the tooth flank surface; and / or the second duty cycle corresponding to the occlusal surface is greater than the second duty cycle corresponding to the tooth flank surface.

[0095] For the side surfaces of the teeth, the tooth surface is relatively smooth and flat, and the tooth surface is connected to the gums. Therefore, the side surfaces of the teeth can correspond to a smaller swing frequency and / or a smaller first duty cycle, and a larger rotation range and / or a smaller second duty cycle, so that the brush head can vibrate with less force and sweep with a larger amplitude, while ensuring that the tooth surface cleaning needs are met, the cleaning coverage is improved, and the gum line can also be cleaned.

[0096] For the occlusal surface, the tooth surface has complex pits and fissures, and there are multiple cusp protrusions on both sides of the occlusal surface. Therefore, the occlusal surface can correspond to a larger swing frequency and / or a larger second duty cycle, as well as a smaller rotation range and / or a larger second duty cycle, so that the brush head can vibrate with greater force and sweep with a smaller amplitude, which can improve the cleaning ability of the pits and fissures of the occlusal surface and overcome the cusp resistance, and the cleaning ability of the electric toothbrush will not be wasted due to excessive sweeping.

[0097] In some embodiments, the electric toothbrush has multiple brushing modes, and the occlusal surface has the same swing amplitude corresponding to the multiple brushing modes; and / or, the occlusal surface has the same rotation frequency corresponding to the multiple brushing modes.

[0098] The cleaning effects achieved by different brushing modes may be different. For different brushing modes, the occlusal surface and the corresponding swing amplitudes of multiple brushing modes are the same, and / or the occlusal surface and the corresponding rotation frequencies of multiple brushing modes are the same. This can ensure that the resistance of the tooth tips is overcome without wasting the cleaning ability of the electric toothbrush, thereby reducing the power consumption of the electric toothbrush.

[0099] In some embodiments, the tooth side surfaces correspond to multiple sets of operating parameters corresponding to the multiple brushing modes, and are positively correlated with the cleaning abilities corresponding to the brushing modes.

[0100] Multiple brushing modes correspond to different cleaning effects. The greater the cleaning power of a brushing mode, the larger the parameter value of the operating parameter corresponding to that brushing mode can be; the smaller the cleaning power of a brushing mode (i.e., the greater the degree of care), the smaller the parameter value of the operating parameter corresponding to that brushing mode can be. This can meet the user's needs for different cleaning effects on the tooth side and achieve the cleaning effects corresponding to multiple brushing modes. For example, a brushing mode with weak cleaning power can reduce damage to sensitive gums, while a brushing mode with strong cleaning power can achieve more efficient oral cleaning.

[0101] In some embodiments, the electric toothbrush includes a first brushing mode, a second brushing mode and a third brushing mode, wherein the cleaning ability corresponding to the first brushing mode is less than the cleaning ability corresponding to the second brushing mode, and the cleaning ability corresponding to the second brushing mode is less than the cleaning ability corresponding to the third brushing mode.

[0102] Optionally, the oscillation frequency of the occlusal surface corresponding to the third brushing mode is greater than the oscillation frequency of the occlusal surface corresponding to the second brushing mode, and the oscillation frequency of the occlusal surface corresponding to the second brushing mode is greater than the oscillation frequency of the occlusal surface corresponding to the first brushing mode; and / or, the rotation range of the occlusal surface corresponding to the third brushing mode is equal to the rotation range of the occlusal surface corresponding to the second brushing mode, and the rotation range of the occlusal surface corresponding to the second brushing mode is greater than the rotation range of the occlusal surface corresponding to the first brushing mode.

[0103] Optionally, the oscillation frequency of the occlusal surface corresponding to the first brushing mode is greater than the oscillation frequency of the tooth side surface corresponding to the first brushing mode and the oscillation frequency of the tooth side surface corresponding to the second brushing mode; the oscillation frequency of the occlusal surface corresponding to the first brushing mode is less than the oscillation frequency of the tooth side surface corresponding to the third brushing mode; the oscillation frequency of the occlusal surface corresponding to the second brushing mode and the oscillation frequency of the occlusal surface corresponding to the third brushing mode are both greater than the oscillation frequency of the tooth side surface corresponding to the third brushing mode.

[0104] For example, the operating parameters corresponding to the tooth side surface and the occlusal surface and multiple brushing modes can be shown in Table 1.

[0105] Table 1

[0106] As shown in Table 1, the first brushing mode may be a gentle cleaning mode, the second brushing mode may be a daily cleaning mode, and the third brushing mode may be a strong cleaning mode. The first set of operating parameters may include an oscillation frequency and an oscillation amplitude, and the second set of operating parameters may include a rotation frequency and a rotation range. For the tooth side surfaces in the gentle cleaning mode, the parameter values ​​of the various operating parameters are relatively small, which can ensure that the gum part will not be brushed by the electric toothbrush as much as possible, and will not cause damage to sensitive gums. For the tooth side surfaces in the daily cleaning mode, the oscillation frequency and oscillation amplitude are improved to ensure the cleaning ability, and the rotation frequency and rotation range are increased to improve the cleaning coverage. The brush head can sweep a part of the gums without causing discomfort to the user. For the tooth side surfaces in the strong cleaning mode, the oscillation frequency and oscillation amplitude are further enhanced, which effectively improves the cleaning ability, and the rotation frequency and rotation range are further increased, which increases the cleaning coverage of the electric toothbrush and can efficiently clean the plaque in the gingival sulcus.

[0107] For the occlusal surface in the gentle cleaning mode, daily cleaning mode and strong cleaning mode, a higher oscillation frequency corresponds to ensure the cleaning rate of the pits and fissures on the occlusal surface of the teeth; the oscillation amplitudes corresponding to the three brushing modes are the same, which are all medium oscillation amplitudes, which can help overcome the resistance of the tooth tips; the rotation ranges corresponding to the three brushing modes are smaller, and the rotation frequency is a medium rotation frequency, which allows the brush head to sweep appropriately to help overcome the resistance of the tooth tips, and there will be no problem of waste of cleaning ability caused by excessive sweeping or sweeping too large.

[0108] It should be noted that the specific values ​​of the operating parameters in Table 1 are only used to illustrate the embodiments of the present application and are not used to limit the actual values ​​of the operating parameters.

[0109] In the embodiments of the present application, different oscillation and rotation parameters can be set for the different positions and structural characteristics of the tooth flanks and occlusal surfaces, effectively meeting the different cleaning and care needs of the tooth flanks and occlusal surfaces. In addition, for multiple brushing modes, different oscillation and rotation parameters can be assigned to the tooth flanks and occlusal surfaces, further meeting the user's different cleaning and care needs for the tooth flanks and occlusal surfaces, improving the cleaning and care effects of the electric toothbrush, enhancing the intelligence of the electric toothbrush, and enhancing the user experience.

[0110] In some embodiments, the first set of operating parameters corresponding to the first oral area can be determined based on the first adjustment parameters corresponding to the first oral area, and the first adjustment parameters have a first functional relationship with the first set of operating parameters; the second set of operating parameters corresponding to the first oral area can be determined based on the second adjustment parameters corresponding to the first oral area, and the second adjustment parameters have a second functional relationship with the second set of operating parameters.

[0111] The user can adjust the first set of operating parameters and the second set of operating parameters corresponding to each oral region according to actual needs. The adjustment may include, but is not limited to, adjusting the parameter values ​​corresponding to the operating parameters. In some embodiments, a parameter adjustment interface may be displayed on the electronic device. The parameter adjustment interface may include the first adjustment parameter and the second adjustment parameter. Furthermore, the parameter adjustment interface may also include a parameter adjustment unit, which is used to adjust the first adjustment parameter and the second adjustment parameter.

[0112] The electronic device may be a terminal device that establishes a communication connection with the electric toothbrush, such as a mobile phone, a wearable device (such as smart glasses, a smart watch, etc.), a tablet computer, a laptop computer, a PC (Personal Computer), etc., and may also be a control terminal used in conjunction with the electric toothbrush. The electronic device may also be an electric toothbrush, which may include a display device, and the parameter adjustment interface may be displayed through the display device.

[0113] The user can perform parameter adjustment operations on the parameter adjustment section in the parameter adjustment interface to adjust the first adjustment parameter and the second adjustment parameter. Optionally, the number of the parameter adjustment sections can be two, and the two parameter adjustment sections correspond to the first adjustment parameter and the second adjustment parameter respectively, so that the first adjustment parameter and the second adjustment parameter can be independently adjusted, and the adjustment method is more detailed. Optionally, the number of the parameter adjustment section can also be one, and the user can adjust the first adjustment parameter and the second adjustment parameter at the same time by performing parameter adjustment operations on one parameter adjustment section, which can improve the convenience of parameter adjustment.

[0114] Optionally, the parameter adjustment operations performed on the parameter adjustment part may include, but are not limited to, one or more of sliding operations, dragging operations, selecting operations in a drop-down menu list, filling in numerical values, etc. on the parameter adjustment part.

[0115] The first adjustment parameter has a first functional relationship with the first set of operating parameters, and further, the first adjustment parameter may have a first functional relationship with multiple swing parameters; the second adjustment parameter has a second functional relationship with the second set of operating parameters, and further, the second adjustment parameter may have a second functional relationship with multiple rotation parameters. The first and second functional relationships can be set according to specific needs or determined based on experimental results, and are not limited here. The user only needs to adjust the first and second adjustment parameters to simultaneously adjust multiple swing parameters and multiple rotation parameters, significantly reducing the cost for the user to understand and adjust each operating parameter and improving the convenience of parameter adjustment.

[0116] For example, FIG6A is a schematic diagram of the interface of the parameter adjustment interface in one embodiment. As shown in FIG6A , the parameter adjustment interface 610 may include a parameter adjustment area 612, the adjustment parameter corresponding to the horizontal coordinate of the parameter adjustment area 612 is the vibration intensity, and the adjustment parameter corresponding to the vertical coordinate of the parameter adjustment area 612 is the sweeping force. Among them, the vibration intensity can correspond to the first movement, and the vibration intensity can have a functional relationship with the swing parameters such as the swing frequency and the swing amplitude; the sweeping rate can correspond to the second movement, and the sweeping speed can have a functional relationship with the rotation parameters such as the rotation frequency and the rotation range. By adjusting the parameter adjustment unit 614, the user can simultaneously adjust multiple operating parameters such as the swing frequency, swing amplitude, rotation frequency, and rotation range, and the adjustment method is more convenient.

[0117] Furthermore, the user can also select a target oral region for parameter adjustment in the parameter adjustment interface. The parameter adjustment interface may include multiple selectable oral regions, and the user can select any oral region for parameter adjustment based on actual needs. If the electronic device detects the user's region selection operation, it can respond to the region selection operation and determine the target oral region selected by the user. The target oral region can be any tooth region, any tooth surface, or any tooth surface in any tooth region.

[0118] After determining the selected target oral area, the user can perform parameter adjustment operations on the parameter adjustment portion in the parameter adjustment interface to adjust the first adjustment parameter and the second adjustment parameter. For example, as shown in FIG6A , the parameter adjustment interface 610 may include a tooth surface selection area 616, and the user can select the tooth surface for which parameter adjustment is required in the tooth surface selection area 616 according to actual needs. Optionally, the parameter adjustment interface 610 may also include a tooth area selection area 618, and the user can select the tooth surface for which parameter adjustment is required in the tooth surface selection area 616 according to actual needs. The user can also select the tooth area for which parameter adjustment is required in the tooth area selection area 618 according to actual needs. For example, the tooth side surface and the upper incisor area can be selected, and the selected target oral area is the tooth side surface of the upper incisor area. After determining the selected target oral area, the parameter adjustment operation can be performed on the parameter adjustment portion 614 to adjust the parameter values ​​of the sweeping rate and vibration intensity in the target oral area.

[0119] In some embodiments, the parameter adjustment interface can also display the nursing effects of the first adjustment parameters and the second adjustment parameters corresponding to each oral area configured by the user. For example, Figure 6B is an interface diagram of the parameter adjustment interface in another embodiment. As shown in Figure 6B, the parameter adjustment interface 620 can display the nursing effects corresponding to the first adjustment parameters and the second adjustment parameters corresponding to each oral area configured by the user in the parameter adjustment area. For example, the first adjustment parameters and the second adjustment parameters corresponding to the oral area A belong to the daily cleaning area (the corresponding nursing effect is to meet daily cleaning), and the first adjustment parameters and the second adjustment parameters corresponding to the oral area B belong to the daily cleaning area (the corresponding nursing effect is to meet daily cleaning). Through the parameter adjustment interface, the user can intuitively know the nursing effects of the first adjustment parameters and the second adjustment parameters corresponding to each configured oral area, which can effectively help the user to adjust the parameters and improve the user experience.

[0120] The electronic device can respond to the parameter adjustment operation on the parameter adjustment part, obtain the parameter values ​​corresponding to the first adjustment parameter and the second adjustment parameter in the target oral area, determine the parameter values ​​of each swing parameter included in the first group of motion parameters based on the parameter value corresponding to the first adjustment parameter, and determine the parameter values ​​of each rotation parameter included in the second group of motion parameters based on the parameter value corresponding to the second adjustment parameter. The electronic device can store the parameter values ​​corresponding to each swing parameter and each rotation parameter in the target oral area in correspondence with the target oral area.

[0121] In some embodiments, the electronic device may be a terminal device such as a mobile phone. When a communication connection is established between the terminal device and the electric toothbrush, the terminal device may transmit stored first parameter configuration information to the electric toothbrush. The first parameter configuration information may include one or more oral regions and multiple sets of operating parameters corresponding to each oral region. The electric toothbrush may store the first parameter configuration information transmitted by the terminal device so that the electric toothbrush can operate according to the latest multiple sets of operating parameters for each oral region during subsequent operation.

[0122] In the embodiment of the present application, the user only needs to adjust the first adjustment parameter and the second adjustment parameter to simultaneously adjust multiple swing parameters and multiple rotation parameters, which greatly reduces the cost of the user's understanding and adjustment of various operating parameters and improves the convenience of parameter adjustment.

[0123] As shown in FIG7 , in one embodiment, the above method may further include the following steps:

[0124] Step 702 : receiving multiple sets of updated operating parameters corresponding to the second oral region sent by the terminal device, where the multiple sets of updated operating parameters corresponding to the second oral region are generated by the terminal device in response to a parameter adjustment operation for the second oral region.

[0125] Step 704: If the second oral region and the first oral region are different oral regions, then no response is performed to the updated sets of operating parameters corresponding to the second oral region.

[0126] The user can adjust the multiple sets of operating parameters corresponding to the second oral area on the terminal device, and the terminal device can be connected to the electric toothbrush for communication (such as Bluetooth connection, Wi-Fi connection, etc., but not limited to). After the user completes the parameter adjustment operation, the terminal device can send the updated multiple sets of operating parameters corresponding to the second oral area to the electric toothbrush.

[0127] If the electric toothbrush is currently brushing the oral cavity when it receives the updated multiple sets of operating parameters corresponding to the second oral region sent by the terminal device, the electric toothbrush can determine whether the second oral region is the same as the first oral region where the brush head is currently located. If the second oral region is different from the first oral region, the electric toothbrush does not respond to the updated multiple sets of operating parameters corresponding to the second oral region.

[0128] Optionally, the electric toothbrush does not respond to the updated multiple sets of operating parameters corresponding to the second oral area, which may include the electric toothbrush not storing the updated multiple sets of operating parameters corresponding to the second oral area. Furthermore, the electric toothbrush may also feedback a non-response message to the terminal device. After receiving the non-response message sent by the electric toothbrush, the terminal device may determine that the first oral area where the electric toothbrush is currently performing a brushing operation is different from the second oral area where the user is adjusting the parameters. The terminal device may then output a prompt message, which may be used to indicate that the adjusted operating parameters have not taken effect, or may indicate that the adjusted operating parameters are only effective in the second oral area.

[0129] For example, when an electric toothbrush is brushing the side of a tooth, if it receives multiple sets of operating parameters corresponding to the occlusal surface from a terminal device, it will not respond to the multiple sets of operating parameters corresponding to the occlusal surface. Instead, the terminal device may output a prompt message saying "Only effective on the occlusal surface." This prevents the user-adjusted operating parameters from adversely affecting the current brushing operation of the electric toothbrush.

[0130] In some embodiments, if the second oral region is the same as the first oral region where the brush head is currently located, the multiple sets of operating parameters corresponding to the first oral region can be updated to the updated multiple sets of operating parameters corresponding to the second oral region, and the electric toothbrush can be controlled to perform a combination of multiple motions according to the updated multiple sets of operating parameters. The operating parameters can be updated in a timely manner, and the user can promptly experience the combination of multiple motions driven by the electric toothbrush according to the adjusted operating parameters.

[0131] In an embodiment of the present application, during the brushing operation of the electric toothbrush, if the second oral area where the user adjusts the parameters is different from the first oral area where the electric toothbrush is currently located, the electric toothbrush will not respond to the updated multiple sets of operating parameters corresponding to the second oral area, which can ensure the accuracy of the operation of the electric toothbrush, avoid confusion of the electric toothbrush, and improve the user experience.

[0132] As shown in FIG8 , in some embodiments, the above method may further include the following steps before the step of identifying the first oral region where the electric toothbrush is located in the oral cavity:

[0133] Step 802: In response to the start work instruction, multiple groups of operating parameters corresponding to the tooth side surfaces are obtained.

[0134] Step 804 , based on the multiple sets of operating parameters corresponding to the tooth side surfaces, control the electric toothbrush to perform a combination of multiple motions according to the multiple sets of operating parameters corresponding to the tooth side surfaces.

[0135] When the electric toothbrush starts to clean the oral cavity, it can perform a combination of multiple movements according to the multiple sets of operating parameters corresponding to the side surfaces of the teeth by default. Then the electric toothbrush can identify the first oral area where the brush head is located in the oral cavity. If it is determined that the first oral area is the occlusal surface, the multiple sets of operating parameters corresponding to the occlusal surface can be obtained to control the electric toothbrush to perform a combination of multiple movements according to the multiple sets of operating parameters corresponding to the occlusal surface.

[0136] In an embodiment of the present application, when the electric toothbrush starts to clean the oral cavity, it moves by default according to multiple sets of operating parameters corresponding to the side surfaces of the teeth, which is more in line with the brushing habits of most users. The electric toothbrush does not need to wait until the first oral area is identified before moving, which can avoid misleading the user due to not brushing for a long time due to failure to identify the oral area where the brush head is located.

[0137] In some embodiments, after identifying the first oral area where the electric toothbrush is located in the mouth, the electric toothbrush can also obtain oral health information corresponding to the first oral area, and adjust multiple sets of operating parameters corresponding to the first oral area according to the oral health information, and then control the electric toothbrush to perform a combination of multiple movements according to the adjusted multiple sets of operating parameters corresponding to the first oral area.

[0138] The oral health information corresponding to the first oral region can be used to characterize the health of the first oral region. Optionally, the oral health information may include but is not limited to one or more of gum health, caries information, plaque residue, oral disease information, and the like.

[0139] The gum health level may refer to the health level of the gums contained in the first oral region. The gum health level may be divided into multiple levels, such as very healthy, generally healthy, average healthy, and unhealthy, but not limited thereto. Optionally, the user's gum health level may be determined based on the color of the gums contained in the first oral region, whether the gums are bleeding, etc. For example, if the gums are pink and there is no bleeding, the corresponding gum health level may be very healthy; if the gums are light red and there is no bleeding, the corresponding gum health level may be average healthy; if the gums are red but there is no bleeding, the corresponding gum health level may be average healthy; if the gums are dark red and there is bleeding, the corresponding gum health level may be unhealthy, etc., but not limited thereto. The specific method for determining the gum health level may be based on more and more detailed gum information.

[0140] The caries information can be used to indicate whether caries exist in the first oral region. For example, the caries information may include, but is not limited to, the number of caries present in the first oral region, the location of the caries present, and other information. The greater the number of caries present in the first oral region, the less healthy it is.

[0141] The amount of dental plaque residue may refer to the amount of dental plaque remaining in the first oral region. The greater the amount of dental plaque residue, the less healthy the first oral region is.

[0142] Oral disease information is used to characterize whether there is a disease in the first oral region. For example, oral disease information may include but is not limited to the name of the disease in the first oral region (such as oral ulcers, periodontitis, etc.), the location of the disease, etc.

[0143] The electric toothbrush can adjust multiple sets of operating parameters corresponding to the first oral area based on the oral health information corresponding to the first oral area. Optionally, if the oral health information corresponding to the first oral area indicates that the first oral area is more sensitive (such as the presence of bleeding gums, dental caries, etc.), the operating parameters can be lowered. Optionally, if the oral health information corresponding to the first oral area indicates that the first oral area requires more intensive cleaning (such as a large amount of dental plaque residue, etc.), the operating parameters can be increased.

[0144] After the electric toothbrush adjusts the multiple sets of operating parameters corresponding to the first oral area, the electric toothbrush is controlled to perform a combination of multiple motions according to the adjusted multiple sets of operating parameters corresponding to the first oral area.

[0145] In an embodiment of the present application, the electric toothbrush can adjust the multiple sets of operating parameters corresponding to the first oral area based on the specific health status of the first oral area, so that the adjusted multiple sets of operating parameters are more adapted to the actual cleaning and care needs of the first oral area, thereby improving the cleaning and care effects of the electric toothbrush and improving the intelligence of the electric toothbrush.

[0146] As shown in FIG9 , in one embodiment, a control device 900 for an electric toothbrush is provided, which can be applied to the above-mentioned electric toothbrush. The control device 900 for the electric toothbrush can include a region recognition module 910 and a control module 920 .

[0147] The area recognition module 910 is used to identify the first oral area where the electric toothbrush is located in the oral cavity.

[0155] In one embodiment, the control device 900 of the electric toothbrush further includes a parameter determination module.

[0156] The parameter determination module is used to determine multiple sets of operating parameters corresponding to the first oral area and the target brushing mode according to the target brushing mode currently running the electric toothbrush; wherein, the first oral area corresponds to different sets of operating parameters under different brushing modes.

[0157] In one embodiment, the motion parameters include one or more of motion amplitude, motion frequency, motion strength, motion timing, and motion duration; and the electrical parameters include duty cycle.

[0158] In one embodiment, an electric toothbrush includes a motor; multiple sets of operating parameters include a first set of operating parameters and a second set of operating parameters, and multiple motions include a first motion corresponding to the first set of operating parameters and a second motion corresponding to the second set of operating parameters; the first motion includes the motor's rotor swinging back and forth with a reference position as the zero axis, and the second motion includes the rotor rotating to change the reference position.

[0159] In one embodiment, the first set of operating parameters includes one or more parameters of the swing frequency, first duty cycle and swing amplitude corresponding to the first motion, and the second set of operating parameters includes one or more parameters of the rotation frequency, second duty cycle and rotation range corresponding to the second motion.

[0160] In one embodiment, the first oral area includes a first tooth surface; the first tooth surface is an occlusal surface or a tooth side surface; the oscillation frequency corresponding to the occlusal surface is greater than the oscillation frequency corresponding to the tooth side surface; and / or, the rotation range corresponding to the occlusal surface is smaller than the rotation range corresponding to the tooth side surface; and / or, the first duty cycle corresponding to the occlusal surface is greater than the first duty cycle corresponding to the tooth side surface; and / or, the second duty cycle corresponding to the occlusal surface is greater than the second duty cycle corresponding to the tooth side surface.

[0161] In one embodiment, the occlusal surface and the multiple brushing modes have the same swing amplitude; and / or the occlusal surface and the multiple brushing modes have the same rotation frequency.
