[0017] The embodiments of the present application are described in detail below with reference to the accompanying drawings.

Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in the field without creative work are within the scope of protection of the present application.

[0020] It should be noted that the terms "first", "second", etc. in the specification and claims of the present invention and the above-mentioned drawings are used to distinguish similar objects, and are not necessarily used to describe a specific order or sequence. It should be understood that the data used in this way can be interchanged where appropriate, so that the embodiments of the present invention described herein can be implemented in an order other than those illustrated or described herein. In addition, the terms "including" and "having" and any variations thereof are intended to cover non-exclusive inclusions, for example, a process, method, system, product or device that includes a series of steps or units is not necessarily limited to those steps or units that are clearly listed, but may include other steps or units that are not clearly listed or inherent to these processes, methods, products or devices.

[0021] For the convenience of description, some nouns or terms involved in the embodiments of the present application are explained below:

[0022] Duty cycle refers to the proportion of the time that a signal is in a high level state in a cycle to the entire 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 pulse width modulation (PWM) technology. Pulse width modulation is referred to as pulse width modulation. PWM technology controls the output voltage by changing the duty cycle of the pulse, thereby controlling the working state of the motor. Generally speaking, the larger the duty cycle, the greater the power output of the motor, and the rotation angle of the motor output shaft will increase accordingly; conversely, the smaller the duty cycle, the smaller the power output of the motor, and the rotation angle of the motor output shaft will decrease accordingly.

[0023] In the current related technology, electric toothbrushes make the brush head generate high-frequency vibrations to break down toothpaste into fine foams, deeply clean the gaps between teeth, and achieve teeth cleaning. However, this method has a small cleaning area and a poor teeth cleaning effect.

[0024] In view of this, 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 and sweeps at the same time, so that the oral cavity can be cleaned more comprehensively and deeply, thereby improving the teeth cleaning effect.

[0025] The embodiment of the present application provides an oral care device, which is used to clean teeth. Figure 1 As shown, the oral care device may be an electric toothbrush, comprising a cleaning portion 11, a gripping portion 12, an actuating component 13 and a control component 14. Among them:

[0026] The connection between the cleaning part 11 and the gripping part 12 is a detachable connection or a fixed connection. During the use of the oral care device, the user grasps the gripping part 12, puts the cleaning part 11 connected to the gripping part 12 into the oral cavity, and uses the cleaning part 11 to clean or care for the oral cavity or teeth.

[0027] The control assembly 14 and the actuating assembly 13 may be disposed inside the gripping portion 12. The actuating assembly 13 may include an output shaft 131, and the output shaft 131 may be connected to the cleaning portion 11. The cleaning portion 11 may include a cleaning unit 111, and the cleaning unit 111 may specifically be a toothbrush head. Specifically, the output shaft 131 may be connected to the cleaning unit 111.

[0028] The control component 14 can be electrically connected to the actuating component 13, and the control component 14 can output a driving signal to the actuating component 13 through a connecting line therebetween. Specifically, the actuating component 13 may include a driving chip. The driving chip can receive the driving signal output by the control component 14, and after power amplification of the driving signal, drive the output shaft of the actuating component 13 to output a periodic cleaning motion. The periodic cleaning motion may include multiple cleaning motions. In this way, the cleaning unit 111 can move under the drive of the output shaft, thereby achieving a teeth cleaning effect.

[0029] It should be noted that, combined with Figure 1 As shown, the positional relationship between the control component 14 and the actuating component 13 inside the grip body 12 is merely exemplary, and the positional relationship between the various components inside the grip body 12 can be adjusted, and the embodiment of the present application does not specifically limit this.

[0030] Specifically, the control component 14 is used to control the operation of the entire oral care device, and can be a microcontroller unit (MCU) or a central processor (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.

[0031] The following is an introduction to the implementation of the periodic cleaning motion output by the output shaft 131 of the actuating assembly 13 .

[0032] First, the output shaft 131 rotates a first angle in a first direction with the first axis as the rotation center line, and then rotates back to the starting position, and this movement is the first movement. Then, the output shaft 131 rotates a second rotation angle in a second direction with the first axis as the rotation center line, and then rotates back to the starting position, and this movement is the second movement. The first direction and the second direction are opposite directions. Specifically, the first axis can be the center line of the output shaft 131.

[0033] In one example, the first direction is clockwise and the second direction is counterclockwise. In another example, the first direction is counterclockwise and the second direction is clockwise.

[0034] The output shaft 131 outputs a plurality of cleaning motions continuously or intermittently / intervally, driving the cleaning unit 111 to vibrate accordingly, forming a periodic cleaning motion, thereby achieving a cleaning effect on the teeth.

[0035] At the same time, among the aforementioned multiple cleaning movements, the first angle of one or more cleaning movements may be greater than the first angle of an adjacent cleaning movement, and the second angle may be less than the second angle of the adjacent cleaning movement. The amplitude of the cleaning movement is the sum of the aforementioned first angle and the second angle. The center position of the amplitude of the above cleaning movement is different from the center position of the amplitude of the adjacent cleaning movement.

[0036] If the first angle of the cleaning motion is equal to the second angle, the center position of the swing angle of the cleaning motion is the starting position. If the first angle of the cleaning motion is greater than the second angle, the center position of the swing angle of the cleaning motion is located on the side of the starting position that is biased toward the first direction. If the first angle of the cleaning motion is less than the second angle, the center position of the swing angle of the cleaning motion is located on the side of the starting position that is biased toward the second direction.

[0037] Exemplarily, the first direction is clockwise, the second direction is counterclockwise, the first angle of cleaning motion A is 3 degrees, the second angle of cleaning motion A is 1 degree, then the swing angle of cleaning motion A is 4 degrees, and the center position of the swing angle of cleaning motion A is the position rotated 1 degree clockwise from the starting position. The first angle of cleaning motion B is 1 degree, the second angle of cleaning motion B is 3 degrees, then the swing angle of cleaning motion B is 4 degrees, and the center position of the swing angle of cleaning motion B is the position rotated 1 degree counterclockwise from the starting position.

[0038] When the driving signal generated by the control component 14 drives the output shaft 131 of the actuator component 13 to output multiple cleaning motions, since the center position of the swing angle of at least part of the cleaning motion is different from the center position of the adjacent cleaning motion, the cleaning unit 111 can produce a sweeping effect, and can imitate the human hand to swing the cleaning unit 111 with the first axis as the rotation center, thereby expanding the cleaning range of the teeth, cleaning the teeth more comprehensively and deeply, and improving the teeth cleaning effect.

[0039] For example, according to the output sequence, the control component 14 generates a driving signal to drive the output shaft 131 of the actuator component 13 to output the first cleaning motion in which the first angle and the second angle are the same; the first angle in the second cleaning motion output is greater than the first angle of the first cleaning motion, and the second angle in the second cleaning motion is less than the second angle of the first cleaning motion, thereby achieving a sweeping effect and a vibration effect; the first angle in the third cleaning motion output can be greater than the first angle of the second cleaning motion, and the second angle in the third cleaning motion is less than the second angle of the second cleaning motion. Of course, as an embodiment, the first angle in the third cleaning motion can be equal to the first angle of the second cleaning motion, and the second angle in the third cleaning motion can be equal to the second angle of the second cleaning motion. There can also be many other embodiments, which are not listed here one by one.

[0040] In the embodiment of the present application, in addition to vibration, the cleaning unit 111 will also produce a sweeping effect, so that the teeth can be cleaned more comprehensively and deeply, thereby improving the teeth cleaning effect.

[0041] In the embodiment of the present application, the control component 14 can drive the output shaft 131 of the actuating component 13 to output multiple cleaning motions by outputting a driving signal, so as to drive the cleaning unit 111 to perform corresponding motions. Therefore, when the output shaft 131 outputs multiple cleaning motions, the cleaning unit 111 will vibrate, thereby cleaning the teeth. At the same time, since the first angle of some cleaning motions can be greater than the first angle of the adjacent cleaning motion, and the second angle is less than the second angle of the adjacent cleaning motion, the center position of the swing angle of these cleaning motions is different from the center position of the swing angle of the adjacent cleaning motion. When the output shaft 131 outputs multiple cleaning motions continuously or at intervals, the cleaning unit 111 will produce a sweeping effect, thereby imitating a human hand swinging a brush head to clean teeth, performing reciprocating sweeping cleaning on the same tooth area, cleaning the oral cavity more comprehensively and deeply, and improving the tooth cleaning effect.

[0042] In some embodiments of the present application, the amplitude of the cleaning motion is the sum of the first angle and the second angle of the cleaning motion: the amplitude of the cleaning motion is the same as the amplitude of the adjacent cleaning motion; or the amplitudes of the multiple cleaning motions are the same.

[0043] In an embodiment of the present application, the sum of the first angle and the second angle of each cleaning motion is also referred to as amplitude. In the aforementioned multiple cleaning motions, the amplitude of at least one cleaning motion can be configured to be the same as the amplitude of its adjacent cleaning motion. Since the first angle of these cleaning motions is greater than the first angle of its adjacent cleaning motion, and the second angle is less than the second angle of its adjacent cleaning motion. This makes the center position of the swing angle of these cleaning motions different from the center position of the swing angle of its adjacent cleaning motion. Therefore, when the output shaft 131 outputs these cleaning motions and their adjacent cleaning motions, the center position of the swing angle of the cleaning motion will rotate, and the cleaning unit 111 produces a sweeping effect, which can improve the teeth cleaning effect.

[0044] Exemplarily, the cleaning motion here and the adjacent cleaning motion can be the aforementioned cleaning motion A and cleaning motion B, respectively, both of which have an amplitude of 4 degrees, but their first angles and second angles are not equal, so the center positions of the swing angles of the two are also different.

[0045] In addition, in the aforementioned multiple cleaning motions, all cleaning motions can be configured to have the same amplitude. Among them, the first angle of at least one cleaning motion in these cleaning motions is greater than the first angle of the adjacent cleaning motion, and the second angle is less than the second angle of the adjacent cleaning motion. The first angle of the remaining cleaning motions may be equal to or unequal to the first angle of the adjacent cleaning motion (unequal includes greater than and less than), and the second angle of the remaining cleaning motions may also be equal to or unequal to the second angle of the adjacent cleaning motion, which is not limited in the embodiments of the present application. Since when the above cleaning motions are output, while the cleaning unit 111 produces a sweeping effect, the amplitude of each cleaning motion is maintained at a constant value, the output cleaning motion can be made regular and not messy, thereby improving the cleaning effect.

[0046] In some embodiments of the present application, in order of output: the control component 14 generates a driving signal so that the first angle of the current cleaning movement is not less than the first angle of the previous cleaning movement, and the second angle of the current cleaning movement is not greater than the second angle of the previous cleaning movement, until the first angle of the cleaning movement reaches a first preset threshold value; and / or the control component 14 generates a driving signal so that the first angle of the current cleaning movement is not greater than the first angle of the previous cleaning movement, and the second angle of the current cleaning movement is not less than the second angle of the previous cleaning movement, until the first angle of the cleaning movement reaches a second preset threshold value.

[0047] In the embodiment of the present application, the output shaft 131 of the actuator assembly 13 can output multiple periodic cleaning movements under the drive of the driving signal generated by the control assembly 14. According to the output sequence of the cleaning movements, under the drive of the driving signal, the first angle of the current cleaning movement output by the output shaft 131 can be greater than or equal to the first angle of the previous cleaning movement, and the second angle of the current cleaning movement can be less than or equal to the second angle of the previous cleaning movement, so that the first angle of the cleaning movement increases continuously or at intervals, and correspondingly, the second angle decreases continuously or at intervals, so that the cleaning unit 111 sweeps along the first direction until the first angle of the cleaning movement reaches the first preset threshold.

[0048] The first preset threshold determines the maximum swing angle of the cleaning unit 111 in the first direction, that is, determines the cleaning sweep range of the cleaning unit 111 in the first direction. The user can set the size of the first preset threshold according to his actual needs. For example, the first preset threshold can be an angle value less than 20 degrees, 16 degrees or 12 degrees.

[0049] Similarly, the control component 14 can generate a drive signal according to the output sequence of the cleaning motion, so that under the drive of the drive signal, the first angle of the current cleaning motion output by the output shaft 131 is less than or equal to the first angle of the previous cleaning motion, and the second angle of the current cleaning motion is greater than or equal to the second angle of the previous cleaning motion, so that the first angle of the cleaning motion is continuously or intermittently reduced, and the second angle is continuously or intermittently increased, so that the cleaning unit 111 sweeps along the second direction until the first angle of the cleaning motion reaches the second preset threshold. The second preset threshold determines the minimum swing angle of the cleaning unit 111 in the first direction. The user can set the size of the second threshold according to his actual needs. In actual applications, the second preset threshold can be as small as 0 degrees. When the first angle of the cleaning motion reaches the second preset threshold, correspondingly, the second angle of the cleaning motion can be an angle value less than 20 degrees, 16 degrees or 12 degrees.

[0050] It should be noted that the first angle of the current cleaning movement can be equal to the first angle of the previous cleaning movement, and the second angle of the current cleaning movement can also be equal to the second angle of the previous cleaning movement. Therefore, in the process of gradually increasing or decreasing the first angle of the cleaning movement, there may be a situation where the first angles of two or more consecutive cleaning movements are equal. Similarly, in the process of gradually decreasing or increasing the second angle of the cleaning movement, there may be a situation where the second angles of two or more consecutive cleaning movements are equal. At this time, the cleaning unit 111 only cleans the teeth by vibration, without sweeping, and performs composite cleaning in multiple ways.

[0051] The output shaft 131 in the embodiment of the present application can also output the above two cleaning motions, so that in the first half cycle, the first angle of the cleaning motion can be increased, and the second angle of the cleaning motion can be reduced, until the first angle of the cleaning motion reaches the first preset threshold. Then, in the second half cycle, the first angle of the cleaning motion is reduced, and the second angle of the cleaning motion is increased, until the first angle of the cleaning motion reaches the second preset threshold. The output shaft 131 can produce the effect of repeatedly sweeping back and forth in the first direction and the second direction by periodically outputting the above two motions.

[0052] In some embodiments of the present application, the control component 14 generates a driving signal to increase the first angle of a current cleaning movement by a preset incremental value compared to the first angle of a previous cleaning movement, and to decrease the second angle of the current cleaning movement by a preset decrement value compared to the second angle of the previous cleaning movement, until the first angle of the cleaning movement reaches a first preset threshold value; and / or, the control component 14 generates a driving signal to decrease the first angle of the current cleaning movement by a preset decrement value compared to the first angle of the previous cleaning movement, and to increase the second angle of the current cleaning movement by a preset incremental value compared to the second angle of the previous cleaning movement, until the first angle of the cleaning movement reaches a second preset threshold value; wherein the incremental value of the current cleaning movement is equal to the decrement value.

[0053] In the embodiment of the present application, driven by the driving signal generated by the control component 14, the output shaft 131 of the actuating component 13 can output multiple periodic cleaning movements. According to the output order of the cleaning movements, driven by the driving signal, the first angle of the current cleaning movement output by the output shaft 131 can be increased by a preset increment value compared to the first angle of the previous cleaning movement, and the second angle of the current cleaning movement can be reduced by a preset decrement value compared to the first angle of the previous cleaning movement, until the first angle of the cleaning movement reaches the first preset threshold value. Since the increment value of the current cleaning movement is equal to the decrement value, the amplitude of the current cleaning movement is the same as the amplitude of the previous cleaning movement, and the rotation angle of the center position of the swing angle of the cleaning unit 111 along the first direction can be equal to the increment value and the decrement value.

[0054] In one example, in a half-cycle of cleaning motion, the driving signal generated by the control component 14 can drive the output shaft 131 of the actuator component 13 to output 12 cleaning motions, namely cleaning motion 1 to cleaning motion 12, the preset increment value and the preset decrement value are both 1 degree, and the sum of the first angle and the second angle of each cleaning motion is 13 degrees. The first angle corresponding to cleaning motion 1 is 1 degree, and the second angle is 12 degrees. The first angle corresponding to cleaning motion 2 is 2 degrees, and the second angle is 11 degrees. The first angle corresponding to cleaning motion 3 is 3 degrees, and the second angle is 10 degrees. By analogy, the first angle corresponding to cleaning motion 11 is 11 degrees, and the second angle is 2 degrees. The first angle corresponding to cleaning motion 12 is 12 degrees, and the second angle is 1 degree.

[0055] Similarly, the control component 14 can generate a driving signal according to the output sequence of the cleaning motion, so that under the drive of the driving signal, the first angle of the current cleaning motion output by the output shaft 131 can be reduced by a preset decrement value compared to the first angle of the previous cleaning motion, and the second angle of the current cleaning motion can be increased by a preset increment value compared to the second angle of the previous cleaning motion, until the first angle of the cleaning motion reaches the second preset threshold value. Since the increment value of the current cleaning motion is equal to the decrement value, the amplitude of the current cleaning motion is the same as the amplitude of the previous cleaning motion, and the rotation angle of the center position of the swing angle of the cleaning unit 111 along the second direction can be equal to the increment value and the decrement value.

[0056] In simple terms, the cleaning motion output by the output shaft 131 of the actuating assembly 13 is in the opposite order to the aforementioned cleaning motion. In one example, the driving signal generated by the control assembly 14 can drive the output shaft 131 of the actuating assembly 13 to output 12 cleaning motions, namely, cleaning motions 13 to 24, with the preset increment value and the preset decrement value both being 1 degree, and the sum of the first angle and the second angle of each cleaning motion being 13 degrees. The first angle and the second angle of cleaning motion 13 are the same as those of cleaning motion 12, the first angle and the second angle of cleaning motion 14 are the same as those of cleaning motion 11, and so on, the first angle and the second angle of cleaning motion 24 are the same as those of cleaning motion 1.

[0057] In addition, for different cleaning motions, the preset increment values ​​relative to the previous cleaning motion may be different, and correspondingly, the preset decrement values ​​relative to the previous cleaning motion are also different, thereby changing the rotation speed of the center position of the swing angle of the cleaning motion.

[0058] The output shaft 131 in the embodiment of the present application continuously adjusts the first angle and the second angle of each cleaning motion, so that the cleaning unit outputs a cleaning motion with the same amplitude but a continuously changing center position of the swing angle, and the center position of the swing angle continuously moves back and forth to form a stable and orderly sweeping vibration. The output shaft 131 can also periodically output the above two motions, thereby producing a continuous back and forth repeated sweeping effect in the first direction and the second direction.

[0059] In some embodiments of the present application, the control component 14 controls the direction of the current flowing into the actuating component 13 to determine the rotation direction of the output shaft 131; and / or, the drive signal is a pulse width modulation signal, and the control component 14 generates a pulse width modulation signal with a first duty cycle, so that the output shaft 131 outputs a first movement correspondingly, and the control component 14 generates a pulse width modulation signal with a second duty cycle, so that the output shaft 131 outputs a second movement correspondingly.

[0060] In the embodiment of the present application, when the direction of the current flowing into the actuating assembly 13 is different, the rotation direction of the output shaft 131 of the actuating assembly 13 is different. Exemplarily, the actuating assembly 13 may include a positive input terminal and a negative input terminal, and when the current flows in from the positive input terminal, the rotation direction of the output shaft 131 of the actuating assembly 13 is clockwise. When the current flows in from the negative input terminal, the rotation direction of the output shaft 131 of the actuating assembly 13 is counterclockwise. Therefore, the control assembly 14 can control the rotation direction of the output shaft 131 to be clockwise or counterclockwise by controlling the direction of the current flowing into the actuating assembly 13.

[0061] The driving signal may be a pulse width modulation signal, and the duty cycle of the pulse width modulation signal determines the size of the first angle and the second angle of rotation of the output shaft 131. The control component 14 may generate a pulse width modulation signal with a first duty cycle, and under the drive of the pulse width modulation signal, the output shaft 131 of the actuator component 13 may output a first motion, and the first angle of the first motion depends on the size of the first duty cycle. The larger the first duty cycle, the larger the first angle.

[0062] Similarly, the control component 14 can also generate a pulse width modulation signal with a second duty cycle. Under the drive of the pulse width modulation signal, the output shaft 131 of the actuator component 13 can output a second motion, and the second angle of the second motion depends on the size of the second duty cycle. The larger the second duty cycle, the larger the second angle.

[0063] In some embodiments of the present application, the sum of the first duty cycle and the second duty cycle corresponding to the cleaning motion is the output; among the multiple cleaning motions, the outputs of at least two cleaning motions are the same; or, the outputs of the multiple cleaning motions are the same.

[0064] In the embodiment of the present application, the duty cycle of the driving signal corresponding to the first motion is the first duty cycle, and the duty cycle of the driving signal corresponding to the second motion is the second duty cycle. The sum of the first duty cycle and the second duty cycle can be referred to as the output. Among the multiple cleaning motions, the outputs of at least two cleaning motions can be made the same, so that the amplitudes of these cleaning motions can be made the same.

[0065] In addition, among the aforementioned multiple cleaning movements, all cleaning movements can be configured to have the same output, so that the amplitudes of all cleaning movements can be the same. Among them, the first angle of at least one cleaning movement among these cleaning movements is greater than the first angle of the adjacent cleaning movement, and the second angle is less than the second angle of the adjacent cleaning movement. When outputting these cleaning movements, the cleaning unit 111 will produce a sweeping effect. The first angles of the remaining cleaning movements may be equal to or unequal to the first angles of the adjacent cleaning movements, and the second angles of the remaining cleaning movements may be equal to or unequal to the second angles of the adjacent cleaning movements, and the embodiments of the present application are not limited to this.

[0066] Since the amplitude of each cleaning motion is kept at a constant value when outputting the above cleaning motions, the output cleaning motions can be regular and not messy, thereby improving the teeth cleaning effect.

[0067] In some embodiments of the present application, the control component 14 generates a pulse width modulation signal for adjusting the first duty cycle and a pulse width modulation signal for adjusting the second duty cycle, so that the first angle of the current cleaning movement is not less than the first angle of the previous cleaning movement, and the second angle of the current cleaning movement is not greater than the second angle of the previous cleaning movement, until the first duty cycle of the cleaning movement reaches a third preset threshold value; and / or, the control component 14 generates a pulse width modulation signal for adjusting the first duty cycle and a pulse width modulation signal for adjusting the second duty cycle, so that the first angle of the current cleaning movement is not greater than the first angle of the previous cleaning movement, and the second angle of the current cleaning movement is not less than the second angle of the previous cleaning movement, until the first duty cycle of the cleaning movement reaches a fourth preset threshold value.

[0068] In an embodiment of the present application, under the drive of the driving signal generated by the control component 14, the output shaft 131 of the actuating component 13 can output multiple periodic cleaning movements. The control component 14 can generate a pulse width modulation signal for adjusting the first duty cycle and a pulse width modulation signal for adjusting the second duty cycle according to the output order of the cleaning movement, so that under the drive of the pulse width modulation signal, the first angle of the current cleaning movement is greater than or equal to the first angle of the previous cleaning movement, and the second angle of the current cleaning movement is less than or equal to the second angle of the previous cleaning movement, until the first duty cycle of the current cleaning movement reaches the third preset threshold. This makes the center position of the swing angle of the cleaning movement rotate continuously or at intervals in the first direction, producing a sweeping effect. The size of the third preset threshold determines the maximum value of the first angle. When the first duty cycle reaches the third preset threshold, the first angle of the cleaning movement reaches the maximum value, and the center position of the swing angle of the cleaning unit 111 reaches the limit value in the first direction.

[0069] Similarly, the control component 14 can also generate a pulse width modulation signal for adjusting the first duty cycle and a pulse width modulation signal for adjusting the second duty cycle according to the output sequence of the cleaning motion, so that under the drive of the pulse width modulation signal, the first angle of the current cleaning motion is less than or equal to the first angle of the previous cleaning motion, and the second angle of the current cleaning motion is greater than or equal to the second angle of the previous cleaning motion, until the first duty cycle of the current cleaning motion reaches the fourth preset threshold. This makes the center position of the swing angle of the cleaning motion continuously rotate in the second direction, producing a sweeping effect. The size of the fourth preset threshold determines the minimum value of the first angle. When the first duty cycle reaches the fourth preset threshold, the first angle of the cleaning motion reaches the minimum value, and the center position of the swing angle of the cleaning unit 111 reaches the limit value in the second direction.

[0070] It should be noted that the first duty cycle of the current cleaning movement may be equal to the first duty cycle of the previous cleaning movement, and the second duty cycle of the current cleaning movement may also be equal to the second duty cycle of the previous cleaning movement. Therefore, when the first duty cycle of the cleaning movement increases / decreases continuously or at intervals, the first duty cycle and the first angle of two or more consecutive cleaning movements may be equal. Similarly, when the second duty cycle of the cleaning movement decreases / increases continuously or at intervals, the second duty cycle and the second angle of two or more consecutive cleaning movements may be equal. At this time, the cleaning unit 111 cleans the teeth only by vibration, without sweeping.

[0071] The output shaft 131 in the embodiment of the present application can also output the above two cleaning motions, so that by adjusting the duty cycle of the pulse width modulation signal, in the first half cycle, the first angle of the current cleaning motion increases continuously or at intervals, and the second angle decreases continuously or at intervals, and the center position of the swing angle of the cleaning motion first rotates in the first direction to form a sweep in the first direction. Then, in the second half cycle, the first angle of the cleaning motion decreases continuously or at intervals, and the second angle increases continuously or at intervals, and the center position of the swing angle of the cleaning motion rotates in the second direction to form a sweep in the second direction. The output shaft 131 can produce the effect of repeatedly sweeping back and forth in the first direction and the second direction by periodically outputting the above two motions.

[0072] In some embodiments of the present application, the cleaning motions in the periodic motion have the same output quantity, in order of output: the control component 14 generates a pulse width modulation signal that increases the first duty cycle and decreases the pulse width modulation signal of the second duty cycle, so that the first angle of the current cleaning motion is greater than the first angle of the previous cleaning motion, and the second angle of the current cleaning motion is less than the second angle of the previous cleaning motion, until the first duty cycle of the cleaning motion reaches a third preset threshold value; and / or the control component 14 generates a pulse width modulation signal that decreases the first duty cycle and increases the pulse width modulation signal of the second duty cycle, so that the first angle of the current cleaning motion is less than the first angle of the previous cleaning motion, and the second angle of the current cleaning motion is greater than the second angle of the previous cleaning motion, until the first duty cycle of the cleaning motion reaches a fourth preset threshold value.

[0073] In the embodiment of the present application, the cleaning motion in the periodic motion has the same output, and therefore, the cleaning motion in the periodic motion has the same amplitude.

[0074] The output shaft 131 of the actuator assembly 13 can output multiple periodic cleaning motions under the drive of the drive signal generated by the control assembly 14. The control assembly 14 can generate a pulse width modulation signal that increases the first duty cycle and decreases the second duty cycle according to the output sequence of the cleaning motions, so that under the drive of the pulse width modulation signal, the first angle of the current cleaning motion is greater than the first angle of the previous cleaning motion, and the second angle of the current cleaning motion is less than the second angle of the previous cleaning motion, until the first duty cycle of the current cleaning motion reaches a third preset threshold.

[0075] The first duty cycle of adjacent cleaning movements in the embodiment of the present application is not equal, and the second duty cycle is also not equal, so that the first angles of adjacent cleaning movements are not equal, and the second angles are also not equal. The first angle of the cleaning movement presents a continuous upward trend, and the second angle presents a continuous downward trend. This makes the center position of the swing angle of the cleaning movement continuously rotate in the first direction, producing a sweeping effect. When the first duty cycle reaches the third preset threshold value, the center position of the swing angle of the cleaning movement reaches the limit value in the first direction.

[0076] Similarly, the control component 14 can generate a pulse width modulation signal that reduces the first duty cycle and increases the second duty cycle according to the output order of the cleaning motion, so that under the drive of the pulse width modulation signal, the first angle of the current cleaning motion is smaller than the first angle of the previous cleaning motion, and the second angle of the current cleaning motion is larger than the second angle of the previous cleaning motion, until the first duty cycle of the current cleaning motion reaches a fourth preset threshold.

[0077] In an embodiment of the present application, the first duty cycle of adjacent cleaning movements is not equal, and the second duty cycle is also not equal, so that the first angles of adjacent cleaning movements are not equal, and the second angles are also not equal. The first angle of the cleaning movement shows a continuous downward trend, and the second angle shows a continuous upward trend. This makes the center position of the swing angle of the cleaning movement continuously rotate in the second direction, producing a sweeping effect. When the first duty cycle reaches the fourth preset threshold value, the center position of the swing angle of the cleaning movement reaches a limit value in the second direction.

[0078] The output shaft 131 in the embodiment of the present application continuously adjusts the first angle and the second angle of each cleaning motion, so that the cleaning unit outputs a cleaning motion with the same amplitude but a continuously changing center position of the swing angle, and the center position of the swing angle continuously moves back and forth to form a stable and orderly sweeping vibration. The output shaft 131 periodically outputs the above two motions, thereby generating an effect of repeated sweeping back and forth in the first direction and the second direction.

[0079] In some embodiments of the present application, the control component 14 determines the amplitude, the first angle and / or the second angle according to user operations, sensor data and / or historical usage data.

[0080] In the embodiment of the present application, the control component 14 can determine the amplitude of the cleaning motion according to the user operation. Specifically, the oral care device can be provided with multiple buttons for selecting the amplitude, and the user can control the amplitude of the cleaning motion by selecting different buttons to generate different control signals.

[0081] For example, if the user prefers to clean the teeth at a larger angle, the amplitude of the cleaning motion can be set to a larger value through corresponding user operations. If the user prefers to clean the teeth at a smaller angle, the amplitude of the cleaning motion can be set to a smaller value through corresponding user operations.

[0082] In addition, the oral care device may be provided with a sensor, such as a gyroscope, so that when different actions of the user are detected, the amplitude of the cleaning motion may be determined according to the type of action.

[0083] Different users have different habits and needs for using oral care devices. The control component 14 can determine the amplitude of the cleaning motion based on the user's habit data for using the oral care device or historical usage data such as the user's customized setting data, so as to make it more in line with the user's personal habits, thereby further enhancing the user's personal experience.

[0084] Similarly, the control component 14 can also use the same method to control and adjust the first angle and / or the second angle, and control and adjust the increment / decrement value of the first angle and / or the second angle, so as to adjust the sweeping speed, amplitude and other parameters.

[0085] In some embodiments of the present application, the control component 14 determines the output amount, the first duty cycle and / or the second duty cycle according to user operations, sensor data and / or historical usage data.

[0086] In the embodiment of the present application, the control component 14 can determine the output size of the cleaning movement according to the user operation. Specifically, the oral care device can be provided with multiple buttons for selecting the output size. The user can control the output size of the cleaning movement by selecting different buttons to generate different control signals, that is, the amplitude of the cleaning movement can be controlled.

[0087] For example, if the user prefers to clean the teeth at a larger angle, the output of the cleaning motion can be set to a larger value, so that the amplitude of the cleaning motion is larger. If the user prefers to clean the teeth at a smaller angle, the output of the cleaning motion can be set to a smaller value, so that the amplitude of the cleaning motion is smaller.

[0088] In addition, the oral care device may be provided with a sensor, such as a gyroscope, so that when different actions of the user are detected, the amplitude of the cleaning motion may be determined according to the type of action.

[0089] Different users have different habits and needs for using oral care devices. The control component 14 can determine the output size of the cleaning motion based on the user's habit data for using the oral care device or historical usage data such as the user's customized setting data, so as to make it more in line with the user's personal habits, thereby further enhancing the user's personal experience.

[0090] Similarly, the control component 14 can also use the same method to control and adjust the first duty cycle and / or the second duty cycle, and control and adjust the increment / decrement value of the first angle and / or the second angle, so as to adjust the sweeping speed, amplitude and other parameters.

[0091] In some embodiments of the present application, the frequency of the actuating component 13 is above 100 Hz.

[0092] In the embodiments of the present application, Figure 2 As shown, the pressure applied to the grip portion 12 also affects the amplitude of the output shaft 131. Exemplarily, the pressure applied by the user to the grip portion 12 may be 0 grams, 50 grams, 100 grams, 150 grams, 300 grams or 400 grams.

[0093] When the pressure applied by the user on the grip 12 is determined, when the frequency of the actuating assembly 13 is different, the amplitude of the output shaft 131 is also different. Since the frequency of the actuating assembly 13 is related to the amplitude of the output shaft 131 of the actuating assembly 13, the amplitude of the output shaft 131 can be changed by changing the frequency of the actuating assembly 13. In order to control the amplitude of the output shaft 131 within a reasonable range, the frequency of the actuating assembly 13 can be controlled to be above 100 Hz.

[0094] Exemplarily, when the frequency of the actuator assembly 13 is above 100 Hz, the amplitude of the output shaft 131 of the actuator assembly 13 is greater than 3 degrees, so that the amplitude is within a reasonable range and the amplitude is not too small, thereby achieving low-frequency and large-angle sweeping vibration, which can more effectively clean the teeth.

[0095] In some embodiments of the present application, the frequency of the actuating assembly 13 is in the range of 100-300 Hz.

[0096] In the embodiment of the present application, in order to better control the amplitude of the output shaft 131, avoid or reduce the force load applied by the user / teeth to the cleaning unit 111, which causes the power of the actuator assembly 13 to weaken, resulting in too small an amplitude, the control component 14 can control the frequency of the drive signal within the range of 100-300Hz, so that the frequency of the actuator assembly 13 is within the range of 100-300Hz, and then the amplitude of the output shaft 131 is within a reasonable range, achieving low-frequency large-angle sweep vibration. In this way, it is possible to avoid damage to the gums when the amplitude is too large, and also to avoid the technical problem of poor cleaning effect on the teeth when the amplitude is too small.

[0097] In some embodiments of the present application, the frequency of the actuating assembly 13 is substantially constant.

[0098] In the embodiment of the present application, the control component 14 can output a driving signal with a basically constant frequency, so that the frequency of the actuator component 13 is also basically constant, and further, the frequency of the output shaft 131 can be basically constant, which can enhance the user experience.
