[0049] Fig. 3 is a structural schematic diagram of an electronic device provided by an embodiment of the present application. DETAILED DESCRIPTION

[0050] In order to facilitate the description, the following describes some nouns or terms related to the embodiments of the present application:

[0051] Duty Cycle refers to the proportion of time that a signal is in a high state within a cycle. In motor control, duty cycle can be used to control the working mode and power output of the motor. Motor control is achieved by using PWM (Pulse Width Modulation) technology. PWM technology controls the size of the output voltage by changing the duty cycle of the pulse, thereby controlling the working state of the motor. Generally, the greater the duty cycle, the greater the power output of the motor, and the rotation angle of the motor output shaft will also increase accordingly; on the contrary, the smaller the duty cycle, the smaller the power output of the motor, and the rotation angle of the motor output shaft will also decrease accordingly.

[0052] In the related art, an electric toothbrush generates high-frequency vibrations to the brush head to decompose toothpaste into fine foam and clean the gaps between teeth. However, this method has a small cleaning area and poor tooth cleaning effect.

[0053] Therefore, the embodiments of the present application provide an oral care device, a control method, an electronic device, and a storage medium. During the operation of the oral care device, the brush head vibrates at a high frequency while also performing a sweeping motion, thereby more comprehensively and deeply cleaning the oral cavity and improving the tooth cleaning effect.

[0054] The embodiments of the present application provide an oral care device for cleaning teeth. Specifically, as shown in FIG. 1, the oral care device can include a cleaning part 11, a holding part 12, an actuating assembly 13, and a control assembly 14. Among them:

[0055] The connection between the cleaning part 11 and the holding part 12 is detachable or fixed. During use of the oral care device, the user holds the holding part 12 and places the cleaning part 11 connected to the holding part 12 into the oral cavity to clean or care for the oral cavity or teeth using the cleaning part 11.

[0056] Since the cleaning part 11 is in frequent contact with the teeth during the cleaning or care process, the cleaning part 11 is more severely worn or abraded than the holding part 12 during use and needs to be replaced in a timely manner. The detachable connection between the cleaning part 11 and the holding part 12 allows the user to replace the cleaning part 11 more conveniently when it needs to be replaced, thereby improving the user's experience.

[0057] The control assembly 14 and the actuating assembly 13 can be arranged inside the holding part 12. The actuating assembly 13 can include an output shaft 131, which can be connected to the cleaning part 11. The cleaning part 11 can include a cleaning unit 111, which can be a toothbrush head. Specifically, the output shaft 131 can be connected to the cleaning unit 111.

[0058] The control component 14 can be electrically connected with the actuating component 13, and the control component 14 can output a driving signal to the actuating component 13 through the connection line therebetween. Specifically, the actuating component 13 can include a driving chip. The driving chip can receive the driving signal output by the control component 14, amplify the power of the driving signal, and then drive the output shaft of the actuating component 13 to output a cleaning motion. In this way, the cleaning unit 111 can move under the driving of the output shaft, thereby achieving the tooth cleaning effect.

[0059] It should be noted that, in combination with FIG. 1, the positional relationship between the control component 14 and the actuating component 13 inside the holding body 12 is only exemplary, and the positional relationship of various components inside the holding body 12 can be adjusted, which is not specifically limited in the embodiments of the present application.

[0060] Specifically, the control component 14 is used to control the operation of the entire oral care device, which can be a microcontroller unit (MCU) or a central processing unit (CPU) of the oral care device. The actuating component 13 can be a motor, such as a sonic motor, and the output shaft 131 is the motor shaft of the motor. As an embodiment, an open-loop control method is adopted in the embodiments of the present application, the control component 14 adjusts the driving signal, including but not limited to the current direction of the actuating component 13, the duty cycle of the pulse width modulation signal, etc., thereby achieving the output control of the output shaft 131 of the actuating component 13. The real-time position of the output shaft 131 can be obtained, the sweep vibration cleaning is achieved, the control method is more simple, the sensor for detecting the position of the output shaft 131 is not needed, the production cost is reduced, the interference of sensor failure or error data is avoided, and the operation stability and accuracy are ensured.

[0061] The implementation of the output cleaning motion of the output shaft 131 of the actuating component 13 will be introduced below.

[0062] First, the output shaft 131 rotates a first rotation angle along a first direction with the first axis as the rotation center line, and then the output shaft 131 rotates a second rotation angle along a second direction with the first axis as the rotation center line. The first direction and the second direction are opposite directions. Specifically, the first axis can be the center line of the output shaft 131.

[0063] In one example, the first direction is the clockwise direction, and the second direction is the counterclockwise direction. In another example, the first direction is the counterclockwise direction, and the second direction is the clockwise direction.

[0064] When the output shaft 131 periodically outputs the cleaning motion, the cleaning unit 111 will generate high-frequency vibration, thereby achieving the cleaning effect on the teeth.

[0065] Meanwhile, the first rotation angle can be greater than the second rotation angle, or can be less than the second rotation angle. For the convenience of description, when the first rotation angle of the first movement is greater than the second rotation angle of the second movement, the cleaning movement can be referred to as a first cleaning movement. When the first rotation angle of the first movement is less than the second rotation angle of the second movement, the cleaning movement can be referred to as a second cleaning movement.

[0066] In a first cleaning movement, the output shaft 131 rotates in a first direction by an angle of a difference between the first rotation angle and the second rotation angle. For example, the first direction is a clockwise direction, the first rotation angle is 1 degree, and the second rotation angle is 0.6 degree. In a first cleaning movement, the output shaft 131 first rotates 1 degree in the clockwise direction, and then rotates 0.6 degree in the counterclockwise direction, and the overall effect is that the output shaft 131 rotates 0.4 degree in the clockwise direction.

[0067] When the output shaft 131 outputs a plurality of first cleaning movements, the output shaft 131 can rotate a larger angle in the first direction, thereby generating a sweeping effect in the first direction, which can simulate the swinging of the cleaning unit 111 in the first direction with the first axis as the center of rotation, and can expand the cleaning range of the teeth.

[0068] Similarly, in a second cleaning movement, the output shaft 131 rotates in a second direction by an angle of a difference between the second rotation angle and the first rotation angle. When the output shaft 131 outputs a plurality of second cleaning movements, a larger angle can be rotated in the second direction, thereby generating a sweeping effect in the second direction, which can simulate the swinging of the cleaning unit 111 in the second direction with the first axis as the center of rotation, and can expand the cleaning range of the teeth.

[0069] In this way, in addition to high-speed vibration, the cleaning unit 111 also generates a sweeping effect, which can more comprehensively and deeply clean the teeth, thereby improving the tooth cleaning effect.

[0070] In the embodiment of the present application, the control assembly 14 can drive the output shaft 131 of the actuating assembly 13 to output a cleaning movement by outputting a driving signal, so as to drive the cleaning unit 111 to perform corresponding movement. Since one cleaning movement includes that the output shaft 131 rotates a first rotation angle in a first direction with the first axis as the center of rotation, and then rotates a second rotation angle in a second direction opposite to the first direction with the first axis as the center of rotation. When the output shaft 131 outputs a plurality of cleaning movements, the cleaning unit 111 will generate high-speed vibration, thereby cleaning the teeth.

[0071] Meanwhile, in a cleaning motion, the output shaft 131 will rotate by a certain angle (specifically, the difference between the first rotation angle and the second rotation angle) in the first direction, or rotate by a certain angle (specifically, the difference between the second rotation angle and the first rotation angle) in the second direction. In the case where the number of cleaning motions output by the output shaft 131 is multiple, the cleaning unit 111 will produce a sweeping effect, so as to imitate the swinging of a human hand to clean teeth with a brush head, and perform reciprocating sweeping cleaning on the same tooth area, so as to more comprehensively and deeply clean the oral cavity and improve the tooth cleaning effect.

[0072] Optionally, in some embodiments of the present application, the control component 14 can further generate the driving signal to drive the output shaft 131 of the actuating component 13 to output a periodic motion. The periodic motion at least includes a first half-cycle motion and / or a second half-cycle motion, wherein the first half-cycle motion includes that the control component 14 generates the driving signal to drive the output shaft 131 to output one or more cleaning motions, so as to rotate the output shaft 131 to a first angle with the first axis as the rotation center line and then rotate back to the starting position; the second half-cycle motion includes that the control component 14 generates the driving signal to drive the output shaft 131 to output one or more cleaning motions, so as to rotate the output shaft 131 to a second angle with the first axis as the rotation center line and then rotate back to the starting position; the rotation direction of the output shaft 131 rotating to the first angle is different from the rotation direction of the output shaft 131 rotating to the second angle.

[0073] In the embodiments of the present application, the control component 14 can drive the output shaft 131 of the actuating component 13 to output a periodic motion by using a driving signal. When the output shaft 131 continuously outputs multiple periodic motions, the output shaft 131 can drive the cleaning unit 111 to produce a continuous sweeping effect.

[0074] Each periodic motion can include a first half-cycle motion and a second half-cycle motion. The first half-cycle motion corresponds to a maximum angle of a first angle, and the second half-cycle motion corresponds to a maximum angle of a second angle. The rotation direction of the output shaft 131 rotating to the first angle is different from the rotation direction of the output shaft 131 rotating to the second angle.

[0075] In one example, the direction of the first half-cycle motion is a first direction, and the direction of the second half-cycle motion is a second direction. In the first half-cycle motion, the output shaft 131 outputs a plurality of first cleaning motions, and the angle differences generated by the plurality of first cleaning motions are accumulated, so that the output shaft 131 can rotate to a first angle along a first direction with the first axis as the rotation center line. Then, the output shaft 131 can also output a plurality of second cleaning motions, and the angle differences generated by the plurality of second cleaning motions are accumulated, so that the output shaft 131 can rotate from the first angle to the starting position along a second direction with the first axis as the rotation center line.

[0076] Similarly, in the second half-cycle motion, the output shaft 131 outputs a plurality of second cleaning motions, and the angle differences generated by the plurality of second cleaning motions are accumulated, so that the output shaft 131 can rotate from the starting position to a second angle along a second direction with the first axis as the rotation center line. Then, the output shaft 131 can also output a plurality of first cleaning motions, and the angle differences generated by the plurality of first cleaning motions are accumulated, so that the output shaft 131 can rotate from the second angle to the starting position along a first direction with the first axis as the rotation center line.

[0077] The starting position can be a zero position, or a position corresponding to any angle from 0 to 360 degrees with the first axis as the rotation center line relative to the zero position. The embodiments of the present application do not limit this.

[0078] The rotation direction of the output shaft 131 rotating to the first angle and the rotation direction of the output shaft 131 rotating to the second angle are located on two sides of the starting position, and the rotation directions of the two are opposite. For example, the angle reached by rotating 10 degrees clockwise from the starting position is the first angle, and the angle reached by rotating 10 degrees counterclockwise from the starting position is the second angle.

[0079] It can be understood that when the rotation direction of the first half-cycle movement is the second direction and the rotation direction of the second half-cycle movement is the first direction, the implementation manner is similar to the above description, and details are not described herein again. Thus, in the same periodic movement, the output shaft 131 outputs a plurality of cleaning movements, and the cleaning movements constitute a periodic movement as a unit movement. Compared with the conventional electric toothbrush cleaning mode, the brush head can only perform one-time reciprocating cleaning in one period of movement. The embodiment of the present application enables the cleaning unit 111 to perform multiple sweeping on the same position in one period of movement, simulates the swinging of the brush head by the human hand to clean the teeth, but the cleaning times and cleaning speed are much higher than manual cleaning. Therefore, the oral cavity, especially the tooth crevice and other difficult-to-clean positions and the masticatory surface and other positions requiring deep cleaning, can be cleaned more comprehensively and deeply through one or more periodic movements, and a better cleaning effect can be achieved without applying too much force to protect the oral cavity tissues such as the gums of the user from being damaged.

[0080] Optionally, in some embodiments of the present application, the control assembly 14 determines the current direction of the actuating assembly 13 to determine whether the output shaft 131 outputs the first half-cycle movement or the second half-cycle movement.

[0081] In the embodiment of the present application, since the rotation direction of the output shaft 131 is related to the current direction flowing through the actuating assembly 13, the control assembly 14 can determine whether the output shaft 131 outputs the first half-cycle movement or the second half-cycle movement by controlling the current direction flowing through the actuating assembly 13.

[0082] For example, the direction of the first half-cycle movement can be the clockwise direction, and the direction of the second half-cycle movement can be the counterclockwise direction. The actuating assembly 13 can be a motor, and the motor includes a positive electrode and a negative electrode. The control assembly 14 controls the current direction of the motor to flow from the positive electrode to the negative electrode, so that the output shaft 131 outputs the first half-cycle movement. The control assembly 14 controls the current direction of the motor to flow from the negative electrode to the positive electrode, so that the output shaft 131 outputs the second half-cycle movement.

[0083] Optionally, in some embodiments of the present application, the control assembly 14 periodically modifies the current direction of the actuating assembly 13 to periodically switch the output shaft 131 to output the first half-cycle movement and the second half-cycle movement.

[0084] In the embodiment of the present application, since the control assembly 14 controls the output shaft 131 to output the first half-cycle movement or the second half-cycle movement by changing the current direction of the actuating assembly 13, the control assembly 14 can modify the current direction of the actuating assembly 13 according to a preset period, so that the output shaft 131 switches to output the first half-cycle movement and the second half-cycle movement according to the preset period, thereby driving the cleaning unit 111 to generate a continuous sweeping effect.

[0085] It can be understood that the user can set the length of the preset period according to actual needs, so as to adjust the sweeping speed of the cleaning unit 111.

[0086] Optionally, in some embodiments of the present application, the driving signal is a pulse width modulation signal, and the control component 14 increases and decreases the duty cycle of the pulse width modulation signal according to a preset increment value, so that the output shaft 131 outputs the first half-cycle movement.

[0087] In the embodiments of the present application, the driving signal can be a pulse width modulation signal. The control component 14 can continuously increase the duty cycle of the pulse width modulation signal according to a preset increment value, so that the output shaft 131 rotates to a first angle with the first axis as the rotation center line. Then, the control component 14 continuously decreases the duty cycle of the pulse width modulation signal, so that the output shaft 131 rotates from the first angle to the initial position with the first axis as the rotation center line. When the duty cycle of the pulse width modulation signal reaches the minimum value, the control component 14 modifies the current direction of the actuating component 13, so that it enters the next half-cycle movement.

[0088] It should be noted that the preset increment value can be a constant value, and at this time the control component 14 can increase the duty cycle of the pulse width modulation signal at a constant speed. In a specific example, the control component 14 increases the duty cycle of the pulse width modulation signal at a period of 5 ms. For example, at time 0 ms, the control component 14 outputs a pulse width modulation signal with a duty cycle of 10%. At time 5 ms, the control component 14 outputs a pulse width modulation signal with a duty cycle of 11%. At time 10 ms, the control component 14 outputs a pulse width modulation signal with a duty cycle of 12%. At time 15 ms, the control component 14 outputs a pulse width modulation signal with a duty cycle of 13%, and so on.

[0089] In addition, the preset increment value can also be a variable, and at this time the control component 14 can increase the duty cycle of the pulse width modulation signal at a variable speed. The embodiments of the present application do not limit the way in which the control component 14 adjusts the duty cycle of the pulse width modulation signal.

[0090] Optionally, in some embodiments of the present application, the control component 14 increases the duty cycle of the pulse width modulation signal according to a preset increment value, drives the output shaft 131 to output a plurality of cleaning movements, so that the output shaft 131 rotates to a first angle with the first axis as the rotation center line; the control component 14 decreases the duty cycle of the pulse width modulation signal according to a preset increment value, drives the output shaft 131 to output a plurality of cleaning movements, so that the output shaft 131 rotates to the initial position with the first axis as the rotation center line.

[0091] In the embodiments of the present application, the control component 14 increases the duty cycle of the pulse width modulation signal by a preset increment value, and can drive the output shaft 131 to output a cleaning motion, which can be a first cleaning motion or a second cleaning motion.

[0092] The control component 14 increases the duty cycle of the pulse width modulation signal multiple times, and can drive the output shaft 131 to output multiple cleaning motions. The angle difference generated by the multiple cleaning motions is accumulated, and the output shaft 131 can be rotated to the first angle with the first axis as the rotation center line.

[0093] Similarly, the control component 14 decreases the duty cycle of the pulse width modulation signal by a preset increment value, and can also drive the output shaft 131 to output a cleaning motion, which is different from the aforementioned cleaning motion type. When the aforementioned cleaning motion is the first cleaning motion, the cleaning motion is the second cleaning motion. When the aforementioned cleaning motion is the second cleaning motion, the cleaning motion is the first cleaning motion.

[0094] The control component 14 decreases the duty cycle of the pulse width modulation signal multiple times, and can drive the output shaft 131 to output multiple cleaning motions. The angle difference generated by the multiple cleaning motions is accumulated, and the output shaft 131 can be rotated from the first angle to the initial position with the first axis as the rotation center line, thereby completing the first half cycle motion.

[0095] Optionally, in some embodiments of the present application, the rotation direction of the first half cycle motion is the first direction, the control component 14 increases the duty cycle of the pulse width modulation signal according to a preset increment value, drives the actuating component 13 to output multiple cleaning motions with the first rotation angle greater than the second rotation angle, and makes the output shaft 131 rotate to the first angle with the first axis as the rotation center line; the control component 14 decreases the duty cycle of the pulse width modulation signal according to a preset increment value, drives the actuating component 13 to output multiple cleaning motions with the second rotation angle greater than the first rotation angle, and makes the output shaft 131 rotate to the initial position with the first axis as the rotation center line.

[0096] In the embodiments of the present application, the rotation direction of the first half-cycle movement can be the first direction. The control component 14 increases the duty cycle of the pulse width modulation signal by a preset increment value, and can drive the output shaft 131 to output a first cleaning movement. Thus, the duty cycle of the pulse width modulation signal is increased multiple times, and the output shaft 131 can be driven to output multiple first cleaning movements, and the output shaft 131 can be driven to rotate to a first angle along the first axis as the rotation center line in the first direction. For example, the first angle is 8 degrees, the difference between the first rotation angle and the second rotation angle in the first cleaning movement is 0.4 degrees, the control component 14 increases the duty cycle for 20 times, and the output shaft 131 outputs 20 cleaning movements, so that the output shaft 131 can be rotated to the first angle.

[0097] Similarly, the control component 14 decreases the duty cycle of the pulse width modulation signal by a preset increment value, and can drive the output shaft 131 to output a second cleaning movement. Thus, the duty cycle of the pulse width modulation signal is decreased multiple times, and the output shaft 131 can be driven to output multiple second cleaning movements, and the output shaft 131 can be driven to rotate from the first angle to the initial position along the first axis as the rotation center line. For example, the first angle is 8 degrees, the difference between the second rotation angle and the first rotation angle in the second cleaning movement is 0.4 degrees, the control component 14 decreases the duty cycle for 20 times, and the output shaft 131 outputs 20 cleaning movements, so that the output shaft 131 can be rotated from the first angle to the initial position.

[0098] It can be understood that the first direction can be the clockwise direction or the counterclockwise direction. In the second half-cycle movement, the output shaft 131 can be rotated to a second angle and rotated back to the initial position in the same manner, which will not be described in detail here.

[0099] Optionally, in some embodiments of the present application, the rotation direction of the first half-cycle movement is the second direction, the control component 14 increases the duty cycle of the pulse width modulation signal according to a preset increment value, the second rotation angle is greater than the first rotation angle, and the output shaft 131 is rotated to a first angle along the first axis as the rotation center line; the control component 14 decreases the duty cycle of the pulse width modulation signal according to a preset increment value, the first rotation angle is greater than the second rotation angle, and the output shaft 131 is rotated back to the initial position along the first axis as the rotation center line.

[0100] In the embodiments of the present application, the rotation direction of the first half-cycle movement can be the second direction.

[0101] The control component 14 increases the duty cycle of the pulse width modulation signal by a preset increment value, and drives the output shaft 131 to output a second cleaning motion. Thus, the control component 14 increases the duty cycle of the pulse width modulation signal multiple times, and drives the output shaft 131 to output multiple second cleaning motions. The angle difference generated by the multiple second cleaning motions is accumulated, and the output shaft 131 is rotated to the first angle along the second direction with the first axis as the rotation center line. For example, the first angle is 10 degrees, the difference between the second rotation angle and the first rotation angle in the second cleaning motion is 0.4 degrees, the control component 14 increases the duty cycle 25 times, and the output shaft 131 outputs 25 second cleaning motions, so that the output shaft 131 is rotated to the first angle.

[0102] Similarly, the control component 14 decreases the duty cycle of the pulse width modulation signal by a preset increment value, and drives the output shaft 131 to output a first cleaning motion. Thus, the control component 14 decreases the duty cycle of the pulse width modulation signal multiple times, and drives the output shaft 131 to output multiple first cleaning motions. The angle difference generated by the multiple first cleaning motions is accumulated, and the output shaft 131 is rotated from the first angle to the initial position with the first axis as the rotation center line. For example, the first angle is 10 degrees, the difference between the first rotation angle and the second rotation angle in the first cleaning motion is 0.4 degrees, the control component 14 decreases the duty cycle 25 times, and the output shaft 131 outputs 25 second cleaning motions, so that the output shaft 131 is rotated from the first angle to the initial position with the first axis as the rotation center line.

[0103] It can be understood that, in the second half-cycle motion, the output shaft 131 can be rotated to the second angle and rotated back to the initial position in the same manner, which is not described in detail herein.

[0104] Optionally, in some embodiments of the present application, the control component 14 also drives the actuating component 13 to output periodic vibrations with different rotation directions but the same rotation angle.

[0105] In the embodiments of the present application, in order to facilitate description, the cleaning motion with different rotation directions but the same rotation angle can be referred to as a third cleaning motion. The control component 14 can also drive the actuating component 13 to output the third cleaning motion, so that the cleaning unit 111 performs high-frequency vibration with the fixed position as the center and cleans the teeth. The control component 14 can drive the output shaft 131 of the actuating component 13 to output the first cleaning motion and the third cleaning motion by controlling the driving signal, so as to improve the cleaning effect on the teeth.

[0106] For example, the control component 14 can drive the output shaft 131 to output a first cleaning motion, then output a third cleaning motion, and then output a first cleaning motion and a third cleaning motion, so that the first cleaning motion and the third cleaning motion are output in a cross-mixed manner.

[0107] Of course, the above is only an example. The control component 14 can drive the output shaft 131 to output M first cleaning motions, and then output N third cleaning motions, so that the first cleaning motions and the third cleaning motions are periodically output in a cross-mixed manner. The values of M and N can be determined according to actual needs. Similarly, the control component 14 can also drive the output shaft 131 to output the second cleaning motion and the third cleaning motion in a mixed manner.

[0108] Optionally, in some embodiments of the present application, the control component 14 determines the first rotation angle and / or the second rotation angle according to user operation, sensing data, and / or historical use data.

[0109] In the embodiments of the present application, the control component 14 can determine the angle of the first rotation angle and / or the second rotation angle according to user operation. Specifically, a plurality of keys for selecting the angle of the first rotation angle and / or the second rotation angle can be provided on the oral care device. The user can generate different control signals by selecting different keys, so as to control the angle of the first rotation angle and / or the second rotation angle.

[0110] In addition, a sensor, such as a gyroscope, can be provided in the oral care device. The sensor can be used to detect the type of user action, and the control component 14 can control the angle of the first rotation angle and / or the second rotation angle according to the type of action.

[0111] Different users have different habits and needs when using the oral care device. The control component 14 can determine the angle of the first rotation angle and / or the second rotation angle based on habit data of the user using the oral care device or historical use data such as user custom setting data, and further adjust the difference between the first rotation angle and the second rotation angle, so as to adjust the sweeping range, speed, and / or force, so as to make it more in line with the personal habits of the user, and thus further improve the user experience.

[0112] Optionally, in some embodiments of the present application, the control component 14 determines the first angle and / or the second angle according to user operation, sensing data, and / or historical use data.

[0113] In the embodiments of the present application, the control component 14 can determine the angle size of the first angle and / or the second angle according to user operation. Specifically, a plurality of keys for selecting the first angle size and the second angle size can be provided on the oral care device, and the user can control the angle size of the first angle and / or the second angle by selecting different keys to generate different control signals.

[0114] Specifically, if the user prefers to clean the teeth at a larger angle, the first angle and the second angle can be set to a larger value. If the user prefers to clean the teeth at a smaller angle, the first angle and the second angle can be set to a smaller value.

[0115] In addition, a sensor such as a gyroscope can be provided in the oral care device. When different actions of the user are detected, the angle size of the first angle and / or the second angle can be determined according to the type of the action.

[0116] Different users have different habits and needs when using the oral care device. The control component 14 can determine the angle size of the first angle and / or the second angle based on habit data of the user using the oral care device or historical use data such as user custom setting data, so as to make it more in line with the personal habits of the user, thereby further improving the personal experience of the user.

[0117] Optionally, in some embodiments of the present application, the control component 14 determines the preset increment value and / or the duty cycle of the pulse width modulation signal according to user operation, sensing data and / or historical use data.

[0118] In the embodiments of the present application, the control component 14 can determine the preset increment value and / or the duty cycle of the pulse width modulation signal according to user operation. Specifically, a plurality of keys for selecting the preset increment value size can be provided on the oral care device, and the user can control the preset increment value size by selecting different keys to generate different control signals. The larger the preset increment value, the faster the sweeping speed of the cleaning unit 111.

[0119] Similarly, the control component 14 can also control the duty cycle of the pulse width modulation signal in the same way.

[0120] In addition, a sensor such as a gyroscope can be provided in the oral care device. When different actions of the user are detected, the angle size of the first angle and / or the second angle can be determined according to the type of the action.

[0121] Different users have different habits and needs for using the oral care device, and the control component 14 can determine the preset increment value and / or the duty cycle of the pulse width modulation signal based on historical use data such as habit data of the user for using the oral care device or custom setting data of the user, so as to make it more in line with the personal habits of the user, and thus the personal experience of the user can be further improved.

[0122] Optionally, in some embodiments of the present application, the control component 14 determines the frequency of the actuating component 13 using the driving signal.

[0123] In the embodiments of the present application, since the frequency of the actuating component 13 is equal to the frequency of the driving signal output by the control component 14, the control component 14 can determine the frequency of the actuating component 13 by controlling the frequency of the driving signal. For example, the control component 14 outputs a driving signal with a frequency of 200 Hz, which can make the frequency of the actuating component 13 be 200 Hz. Since the sizes of the first angle and the second angle are related to the frequency of the actuating component 13, the control component 14 can control the sizes of the first angle and the second angle by controlling the frequency of the driving signal.

[0124] Optionally, in some embodiments of the present application, the frequency of the actuating component 13 is 100 Hz or more.

[0125] In the embodiments of the present application, since the frequency of the actuating component 13 is related to the swing angle (i.e. the first angle and the second angle) of the output shaft 131 of the actuating component 13, the size of the swing angle of the output shaft 131 can be changed by changing the frequency of the actuating component 13. In order to control the size of the swing angle of the output shaft 131 within a reasonable range, the frequency of the actuating component 13 can be controlled to be 100 Hz or more.

[0126] For example, when the frequency of the actuating component 13 is 100 Hz or more, the swing angle of the output shaft 131 of the actuating component 13 is greater than 3 degrees, so that the size of the swing angle is within a reasonable range, and the swing angle is not too small, which can more effectively clean the teeth.

[0127] Optionally, in some embodiments of the present application, the frequency of the actuating component 13 is within the range of 100-300 Hz.

[0128] In the embodiments of the present application, in order to better control the swing angle of the output shaft 131, avoid or reduce the force load applied by the user / dental on the cleaning unit, cause the power of the actuating assembly 13 to weaken, and cause the swing angle to be too small, the control assembly 14 can control the frequency of the driving signal to be in the range of 100-300 Hz, so that the frequency of the actuating assembly 13 is in the range of 100-300 Hz, and then the angle of the swing angle of the output shaft 131 is in a reasonable range. In this way, the damage to the gums when the swing angle is too large can be avoided, and the technical problem of poor cleaning effect on the teeth when the swing angle is too small can also be avoided.

[0129] Optionally, in some embodiments of the present application, the frequency of the actuating assembly 13 is substantially constant.

[0130] In the embodiments of the present application, the control assembly 14 can output a driving signal with a substantially constant frequency, so that the frequency of the actuating assembly 13 is also substantially constant, and further can make the swing angle of the output shaft 131 be substantially constant, which can improve the user's experience.

[0131] Optionally, in some embodiments of the present application, the angle range of the first rotation angle and / or the second rotation angle is 0.1-1.5 degrees.

[0132] In the embodiments of the present application, by controlling the angle range of the first rotation angle and the second rotation angle to be 0.1-1.5 degrees, the angles of the first rotation angle and the second rotation angle can be in a more reasonable range, and the teeth can be effectively cleaned. At the same time, the maximum difference between the first rotation angle and the second rotation angle is 1.4 degrees, so that the difference between the first rotation angle and the second rotation angle is not too large, and the output shaft 131 cannot be effectively cleaned.

[0133] Optionally, in some embodiments of the present application, the angle range of the first rotation angle and / or the second rotation angle is 0.3-1.0 degrees.

[0134] In the embodiments of the present application, by controlling the angle range of the first rotation angle and the second rotation angle to be 0.3-1.0 degrees, the angles of the first rotation angle and the second rotation angle can be in a more reasonable range, and the maximum difference between the first rotation angle and the second rotation angle is 0.7 degrees, so that the difference between the first rotation angle and the second rotation angle is not too large, and the output shaft 131 cannot be effectively cleaned.

[0135] Optionally, in some embodiments of the present application, the angle range of the first angle and / or the second angle is 6-18 degrees.

[0136] In the embodiments of the present application, the first angle and / or the second angle can be controlled to be within a range of 6 to 18 degrees, so that the harm to the gums caused by the first angle and / or the second angle being too large can be avoided, and the problem of insufficient cleaning of the teeth caused by the first angle and / or the second angle being too small can also be avoided.

[0137] Optionally, in some embodiments of the present application, the first angle and / or the second angle is within a range of 12 to 15 degrees.

[0138] In the embodiments of the present application, the first angle and / or the second angle can be further controlled to be within a range of 12 to 15 degrees, so that the harm to the gums caused by the first angle and / or the second angle being too large can be avoided, and the problem of insufficient cleaning of the teeth caused by the first angle and / or the second angle being too small can also be avoided, and the user experience can be further improved.

Meanwhile, in one cleaning motion, the output shaft 131 rotates by a certain angle along a first direction or rotates by a certain angle along a second direction.
