[0002] Oral hygiene devices (such as electric toothbrushes and oral irrigators) often need to produce sound during use. For example, voice prompts are needed to remind users of the device's usage, or users can listen to music while using the device. Traditionally, speakers are built directly into the device to play audio, such as voice or music, which is costly.

[0003] Therefore, oral cleaning devices that generate sound by controlling the vibration of a motor have appeared on the market, but this type of oral cleaning device has the problem of poor cleaning effect. Summary of the Invention

[0008] In this embodiment, the motor of the oral cleaning device has an output shaft, and the motor includes a first drive unit and a second drive unit. The first drive unit is used to drive the output shaft to perform a first movement, and the second drive unit is used to drive the output shaft to perform a second movement. A first drive signal can be input to the first drive unit so that the first drive unit drives the output shaft to perform a first movement based on the first drive signal. A second drive signal can be input to the second drive unit so that the second drive unit drives the output shaft to perform a second movement based on the second drive signal. The first movement is used to enable the oral cleaning device to clean the oral cavity, and the second movement can generate a target sound. The two drive units of the motor can be controlled separately, one drive unit is used to drive the output shaft to perform a first movement to achieve a cleaning operation, and the other drive unit is used to drive the output shaft to perform a second movement to generate a target sound. The control interference between the two movements can be reduced, so that the motor will not affect the cleaning operation of the oral cavity while generating the target sound, thereby ensuring the cleaning effect of the oral cleaning device.

[0009] As an optional implementation manner, the movement amplitude of the first movement is greater than the movement amplitude of the second movement; and / or,

[0017] As an optional implementation manner, inputting the second driving signal to the second driving unit includes:

[0018] During the process of inputting the first driving signal to the first driving unit, the second driving signal is synchronously inputted to the second driving unit.

[0020] As an optional implementation manner, inputting the second driving signal to the second driving unit includes:

[0021] During the process of inputting the first driving signal to the first driving unit, the second driving signal is input to the second driving unit at intervals of a first time length.

[0022] In this embodiment, the oral cleaning device can generate a target sound at first intervals during the cleaning operation, thereby helping the user better understand the current cleaning progress and further improving the user experience. Furthermore, because the first and second movements of the output shaft do not interfere with each other, the generated musical sound does not affect the cleaning operation. The first movement of the output shaft can continuously drive the cleaning element to perform the cleaning operation without causing any interruption to the user, thereby improving the cleaning effect of the oral cleaning device.

[0023] As an optional implementation manner, inputting the second driving signal to the second driving unit includes:

[0024] When the audio output condition is met, a second driving signal is input to the second driving unit.

[0025] In this embodiment, when the audio output conditions are met, the output shaft of the motor can be controlled to perform a second movement to generate a target sound, which can meet the needs of the oral cleaning device to output prompt voice or prompt music in different scenarios. The first movement and the second movement of the output shaft will not interfere with each other, and the sound generated will not affect the cleaning operation, thereby ensuring the cleaning effect of the oral cleaning device.

[0026] As an optional implementation manner, when the audio output condition is met, inputting the second driving signal to the second driving unit includes:

[0027] When the audio output condition is met, obtaining audio data corresponding to the satisfied audio output condition as audio data to be output;

[0028] A second driving signal is generated according to the audio data to be output, and the second driving signal is input to the second driving unit.

[0029] In this embodiment, the output shaft of the motor can be controlled to produce different target sounds for different audio output conditions to meet the sound playback requirements of the oral cleaning device in different scenarios, thereby improving the richness of the sound played by the oral cleaning device.

[0030] As an optional embodiment, the oral cleaning device further includes a cleaning member, and the motor is used to drive the cleaning member to move;

[0031] The distance between the second driving unit and the cleaning member is smaller than the distance between the first driving unit and the cleaning member.

[0032] In this embodiment, the second driving unit is arranged at a position closer to the cleaning member, so that the path of the target sound generated by the second driving unit driving the output shaft to perform the second movement to be transmitted to the human ear is shorter, thereby improving the sound transmission effect.

[0033] As an optional implementation, the driving power of the first driving unit is greater than the driving power of the second driving unit.

[0034] In this embodiment, the driving power of the first driving unit is greater than the driving power of the second driving unit, so that the output shaft can be driven to perform the first movement more stably, ensuring the cleaning effect of driving the cleaning member to perform the cleaning operation.

[0035] As an optional implementation, the movement direction of the first movement is different from the movement direction of the second movement.

[0036] In this embodiment, the direction of movement of the first movement of the output shaft is different from the direction of movement of the second movement, and the first movement and the second movement will not interfere with each other, thereby ensuring that the movement of the motor to generate the target sound and the movement of the cleaning operation will not interfere with each other, and the cleaning operation will not be affected by the sound generated by the motor, thereby ensuring the cleaning effect.

[0037] As an optional implementation, the first movement includes the output shaft performing reciprocating rotational movement; the second movement includes the output shaft performing telescopic movement.

[0038] In this embodiment, the movement direction of the telescopic motion and the movement direction of the reciprocating rotation motion are perpendicular or nearly perpendicular to each other, which can minimize the force components of each motion and reduce the interference between the telescopic motion and the reciprocating rotation motion.

[0039] As an optional embodiment, the oral cleaning device also includes a cleaning piece, the output shaft is connected to the cleaning piece, and the motor is used to drive the cleaning piece to move; when the output shaft performs the first movement and the second movement at the same time, the motion trajectory of the cleaning piece projected onto the target surface is a curved trajectory.

[0040] In this embodiment, the movement trajectory of the cleaning piece on the tooth surface can be a curved trajectory, which can simulate the way a user holds the oral cleaning device and shakes the oral cleaning device up and down while manually performing care operations, which can have a better cleaning effect on the oral cavity.

[0041] As an optional embodiment, the curved trajectory includes any one of a circular arc curve, a sinusoidal curve trajectory, a spiral curve trajectory, a spring-shaped curve trajectory, and a figure-8 curve trajectory.

[0042] In this embodiment, the output shaft of the motor performs the first motion and the second motion simultaneously, and the cleaning member can form any curved trajectory such as a circular arc trajectory, a sinusoidal curve trajectory, a spiral curve trajectory, a spring-shaped curve trajectory, and a figure-8 curve trajectory on the target surface, which can achieve a better cleaning effect, avoid damaging the gums, and protect oral health.

[0044] In this embodiment, the second movement of the output shaft has a larger amplitude, which can ensure the combined movement of the first movement and the second movement of the output shaft, and can drive the cleaning element to move along a curved trajectory to achieve multi-angle cleaning, further improving the cleaning effect of the oral cleaning device.

[0061] The following will be combined with the drawings in the embodiments of this application to clearly and completely describe the technical solutions in the embodiments of this application. Obviously, the embodiments described are only part of the embodiments of this application, not all of the embodiments. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of this application.

[0062] It should be noted that the terms "including," "having," and any variations thereof in the embodiments and drawings of this application are intended to cover non-exclusive inclusions. For example, a process, method, system, product, or apparatus comprising a series of steps or units is not limited to the listed steps or units, but may optionally include steps or units not listed, or may optionally include other steps or units inherent to the process, method, product, or apparatus.

[0063] It will be understood that the terms "first," "second," etc. used in this application may be used herein to describe various elements, but these elements are not limited by these terms. These terms are only used to distinguish a first element from another element. For example, without departing from the scope of this application, a first drive unit may be referred to as a second drive unit, and similarly, a second drive unit may be referred to as a first drive unit. Both the first drive unit and the second drive unit are drive units, but they are not the same drive unit. The term "plurality" used in this application refers to two or more. The term "and / or" used in this application refers to one of the solutions, or any combination of multiple solutions.

[0064] At present, in order to reduce costs, the desired sound can be produced by controlling the vibration of the motor in the oral cleaning equipment. In this method, an audio signal is generally used to drive the motor vibration to produce sound. Since the audio signal changes irregularly and is usually chaotic, the motor cannot produce vibrations of effective amplitude. During the process of the motor making sounds, the movement of the motor cannot effectively drive the cleaning parts to perform cleaning operations, resulting in poor cleaning effects.

[0065] The embodiments of the present application disclose a control method, device and oral cleaning device, which can allow the motor to generate a target sound without affecting the cleaning operation of the oral cavity, thereby ensuring the cleaning effect of the oral cleaning device.

[0066] Figure 1A FIG. 1 is an application scenario diagram of a control method for an oral cleaning device in one embodiment. Figure 1A As shown, the control method of the oral cleaning device disclosed in the embodiment of the present application can be applied to the oral cleaning device 100, and the oral cleaning device 100 may include but is not limited to an electric toothbrush, an oral irrigator, etc.

[0067] In some embodiments, the oral cleaning device 100 may include a cleaning member 110 and a handle 120, wherein the cleaning member 110 is detachably connected to the handle 120. For example, if the oral cleaning device 100 is an electric toothbrush, the cleaning member may be a brush head, which may be composed of a brush rod and bristles.

[0068] In some embodiments, the handle 120 of the oral cleaning device 100 may be provided with a motor. During operation of the oral cleaning device 100, the motor may be controlled to drive the cleaning element 110 to move, thereby performing an oral care operation, thereby realizing the oral care function of the oral cleaning device 100. For example, if the oral cleaning device 100 is an electric toothbrush, the motor may drive the brush head to move, thereby performing a toothbrush operation.

[0069] Furthermore, the oral cleaning device 100 may be provided with a controller, which may be used to control the operation of the motor.

[0070] For example, Figure 1B FIG. 1 is a schematic diagram of the structure of a motor in one embodiment. Figure 1B As shown, the motor 130 may have an output shaft 132. Further, the output shaft 132 may be connected to the cleaning member 110. When the output shaft 132 moves, the cleaning member 110 may be driven to move.

[0071] In some embodiments, the motor 130 may be a bidirectional motor and may include a first drive unit 134 and a second drive unit 136 . The first drive unit 134 may be configured to drive the output shaft 132 to perform a first motion, and the second drive unit 136 may be configured to drive the output shaft 132 to perform a second motion.

[0072] In an embodiment of the present application, the controller of the oral cleaning device 100 may input a first drive signal to the first drive unit 134, so that the first drive unit 134 drives the output shaft 132 to perform a first movement based on the first drive signal, and the first movement can drive the cleaning member 110 to perform a cleaning operation on the oral cavity. The controller of the oral cleaning device 100 may input a second drive signal to the second drive unit 136, so that the second drive unit 136 drives the output shaft 132 to perform a second movement based on the second drive signal, and the second movement can generate a target sound. Furthermore, when the cleaning member 110 (such as the bristles of the brush head) contacts the user's teeth, the sound generated by the second movement of the output shaft 132 can be transmitted to the human ear by bone conduction, so that the user can hear the target sound generated by the motor.

[0073] In some embodiments, the direction of movement of the first movement of the output shaft 132 is different from the direction of movement of the second movement, and the first movement and the second movement will not interfere with each other, thereby ensuring that the movement of the motor to generate the target sound and the movement of the cleaning operation will not interfere with each other, and the cleaning operation will not be affected by the sound generated by the motor, thereby ensuring the cleaning effect.

[0074] In some embodiments, the first motion described above may include the output shaft 132 performing reciprocating rotational motion, and the second motion may include the output shaft 132 performing telescopic motion. The reciprocating rotational motion of the output shaft 132 may refer to the output shaft 132 performing reciprocating rotational motion around a reference zero axis. The reference zero axis may be an axis parallel to the long axis of the oral cleaning device 100, or an axis having a certain angle with the long axis of the oral cleaning device 100, which is not limited herein. For example, the direction of the reciprocating rotational motion may be as indicated by arrow 150. The telescopic motion of the output shaft 132 may refer to the output shaft 132 performing reciprocating linear motion along the long axis of the oral cleaning device 100. For example, the direction of the telescopic motion may be as indicated by arrow 140.

[0075] Alternatively, the first drive unit 134 and the second drive unit 136 may be magnetic drive mechanisms, each utilizing the magnetic force generated by a magnetic member to drive the output shaft 132 to move. The first drive unit 134 and the second drive unit 136 drive the same output shaft 132, and the telescopic motion and reciprocating rotational motion of the output shaft 132 correspond to different motion directions. Driven by the magnetic forces generated by the first drive unit 134 and the second drive unit 136, respectively, the telescopic motion and reciprocating rotational motion of the output shaft 132 do not interfere with each other.

[0076] Furthermore, the directions of telescopic motion and reciprocating rotation are perpendicular or nearly perpendicular to each other, minimizing the force components of each motion and reducing interference between the telescopic motion and the reciprocating rotation. Furthermore, the first drive unit 134 and the second drive unit 136 share the same output shaft 132, making the structure of the motor 130 more compact. This output shaft 132 allows for more efficient motion transmission, enhancing the sound produced by the output motor and the cleaning operation of the cleaning element 110, thereby improving the sound output and cleaning effectiveness of the oral cleaning device 100.

[0077] In some embodiments, the distance between the second drive unit 136 and the cleaning member 110 may be smaller than the distance between the first drive unit 134 and the cleaning member 110. By arranging the second drive unit 136 closer to the portion where the output shaft 132 extends, that is, by arranging the second drive unit 136 closer to the cleaning member 110, the path for the target sound generated by the second drive unit 136 driving the output shaft 132 to perform the second motion to be transmitted to the human ear can be shortened, thereby improving the sound transmission effect.

[0078] It should be noted that the setting positions of the second drive unit 136 and the first drive unit 134 are not specifically limited in the embodiment of the present application. For example, the first drive unit 134 can also be set at a position closer to the cleaning member 110, and the motor can also produce the target sound without affecting the technical effect of the cleaning operation on the oral cavity.

[0079] In some embodiments, the driving power of the first driving unit 134 may be greater than the driving power of the second driving unit 136. Optionally, the driving power of the driving unit may be determined by one or more of the magnetic field strength generated by the magnetic component of the driving unit, the operating power of the driving unit, the operating current of the driving unit, etc. The driving power of the first driving unit 134 is greater than the driving power of the second driving unit 136, thereby more stably driving the output shaft 132 to perform the first movement, thereby ensuring the cleaning effect of driving the cleaning member 110 to perform the cleaning operation.

[0080] It should be noted that Figure 1BIt is only used to explain and illustrate the structure of the motor involved in the embodiment of the present application, and is not used to limit the specific structure of the motor. The motor may also include Figure 1B The motor structure shown has more parts.

[0081] like Figure 2 As shown, in one embodiment, a control method for an oral cleaning device is provided, which can be applied to the above-mentioned oral cleaning device. The method may include the following steps:

[0082] Step 210 : Input a first driving signal to the first driving unit, so that the first driving unit drives the output shaft to perform a first motion based on the first driving signal. The first motion is used to enable the oral cleaning device to perform a cleaning operation on the oral cavity.

[0083] When the oral cleaning device is in a working state, the oral cleaning device can control the motor to perform a cleaning operation on the oral cavity, wherein the working state may refer to a state in which the oral cleaning device performs a cleaning operation, such as a state in which a toothbrush performs a brushing action.

[0084] When the oral cleaning device is in working condition, the controller can input a first driving signal to the first driving unit. The first driving signal can be used to enable the first driving unit to drive the output shaft to perform a first movement. The first movement of the output shaft can drive the cleaning element to move, thereby realizing a cleaning operation on the oral cavity.

[0085] In some embodiments, the first driving signal may be a driving signal with a certain regularity, and the first motion may be a regular motion. Regular motion refers to a repeatable motion mode, that is, the first motion may be a repetitive and regular motion, thereby generating effective cleaning vibrations to help better clean the oral cavity.

[0086] In some embodiments, the first driving signal may include a pulse signal. The oral cleaning device may generate the first driving signal according to the configured cleaning parameters and input the first driving signal to the first driving unit.

[0087] Furthermore, the first drive signal may include a PWM (Pulse Width Modulation) signal. The oral cleaning device may generate a corresponding PWM signal based on the configured cleaning parameters and transmit the generated PWM signal to the first drive unit of the motor. The first drive unit may drive the output shaft of the motor to perform a first motion based on the PWM signal, thereby ensuring the cleaning effect of the cleaning operation performed by the cleaning member.

[0088] Among them, the cleaning parameters may include but are not limited to cleaning range, cleaning force, cleaning frequency, etc., among which the cleaning range may refer to the operating range of the cleaning part in performing a cleaning operation on the oral cavity, the cleaning force may refer to the force generated by the cleaning part in performing a cleaning operation on the oral cavity, and the cleaning frequency may refer to the number of times the cleaning part performs a cleaning operation on the oral cavity in unit time.

[0089] As an embodiment, cleaning parameters can be pre-configured. For example, the oral cleaning device can be pre-configured with multiple working modes. The cleaning parameters configured in different working modes are different, and the cleaning effects achieved by different working modes may be different. For example, whitening mode, strong mode, soothing mode, etc. can be pre-configured. Among them, the whitening mode helps to whiten the user's teeth, the strong mode helps to help the user clean the teeth better, and the soothing mode can provide a more comfortable brushing method, which is suitable for users with sensitive teeth, etc. The three working modes can correspond to different cleaning parameters respectively.

[0090] Optionally, the cleaning parameters can also be adjusted and configured by the user according to actual needs.

[0091] Furthermore, the cleaning parameter can be reflected in the first motion as a motion parameter of the first motion. For example, taking the first motion as the reciprocating rotational motion of the output shaft as an example, the cleaning range can be the rotation range of the output shaft performing a reciprocating rotational motion, the cleaning force can be the force generated by the reciprocating rotational motion of the output shaft, and the cleaning frequency can be the number of times the output shaft performs reciprocating rotational motion per unit time, that is, the rotation frequency.

[0092] Step 220 , inputting a second driving signal to the second driving unit, so that the second driving unit drives the output shaft to perform a second motion based on the second driving signal, wherein the second motion can generate a target sound; wherein the first motion is different from the second motion.

[0093] When the oral cleaning device needs to output a target sound, a second drive signal can be input into the second drive unit. The second drive signal can be used to enable the second drive unit to drive the output shaft to perform a second movement. The second movement of the output shaft of the motor can transmit an audio signal of the target sound. When the cleaning piece is in contact with the teeth, the audio signal can be transmitted to the human ear through bone conduction, and the user can accurately hear the target sound generated by the oral cleaning device.

[0094] Optionally, the target sound may be speech, music, prompt sound or other sounds, which are not limited here.

[0095] In some embodiments, the second driving signal may include an audio signal. The oral cleaning device may generate the second driving signal according to the audio data to be output, and input the second driving signal to the second driving unit.

[0096] Among them, the audio data to be output may refer to the audio data corresponding to the target sound. Optionally, the audio data to be output may be processed by digital-to-analog conversion and power amplification, and the processed audio signal may be input to the second drive unit as a second drive signal. The second drive unit may drive the output shaft of the motor to perform a second movement according to the second drive signal, so that the motor produces a target sound that matches the audio data to be output.

[0097] Since the first movement and the second movement performed by the output shaft are different, and further, the movement directions of the first movement and the second movement are different, and the first movement and the second movement performed by the output shaft are independently driven by the first drive unit and the second drive unit respectively, the control of the first movement and the second movement will not interfere with each other. In the process of the motor generating the target sound, it will not affect the cleaning operation performed by the cleaning element driven by the motor, and the cleaning effect of the oral cleaning equipment can be guaranteed.

[0098] In an embodiment of the present application, the two drive units of the motor can be controlled separately, one drive unit is used to drive the output shaft to perform a first movement to achieve a cleaning operation, and the other drive unit is used to drive the output shaft to perform a second movement to generate a target sound. This can reduce the control interference between the two movements, so that the motor will not affect the cleaning operation of the oral cavity while generating the target sound, thereby ensuring the cleaning effect of the oral cleaning equipment.

[0099] In some embodiments, the oral cleaning device can generate a target sound while performing a cleaning operation, thereby achieving effects such as playing music while performing a cleaning operation. During the process of inputting a first driving signal to the first driving unit, a second driving signal can be simultaneously input to the second driving unit.

[0100] When the oral cleaning device is in operation, it can play music while performing an oral cleaning operation. The oral cleaning device can generate a first drive signal based on configured cleaning parameters and input the first drive signal to a first drive unit. It can also obtain audio data corresponding to the music to be played, generate a second drive signal based on the audio data, and simultaneously input the second drive signal to a second drive unit. The output shaft simultaneously performs the second movement while performing the first movement, thereby achieving the effect of playing music while performing a cleaning operation.

[0101] Moreover, since the first movement and the second movement of the output shaft will not interfere with each other, the generated musical sound will not affect the cleaning operation. The first movement of the output shaft can continuously drive the cleaning element to perform the cleaning operation without causing a sense of interruption to the user, thereby improving the cleaning effect of the oral cleaning equipment.

[0102] For example, Figure 3AFIG. 1 is a schematic diagram of the output shaft performing the first motion and the second motion in one embodiment. Figure 3A As shown, referring to the motion curve 310 of the first motion and the motion curve 320 of the second motion, the output shaft of the motor performs the first motion while synchronously performing the second motion, thereby generating the target sound while driving the cleaning element to perform the cleaning operation.

[0103] In an embodiment of the present application, the output shaft can be driven synchronously to perform the first movement and the second movement, thereby achieving the effect of playing music while performing the cleaning operation, thereby increasing the fun of users in using the oral cleaning device, and the first movement and the second movement of the output shaft will not interfere with each other, and the generated music sound will not affect the cleaning operation, thereby ensuring the cleaning effect of the oral cleaning device.

[0104] In some embodiments, the oral cleaning device may generate a target sound at intervals during a cleaning operation. During the process of inputting a first driving signal to the first driving unit, a second driving signal may be input to the second driving unit at intervals of a first time duration.

[0105] When the oral cleaning device is in operation, it can play a target sound at regular intervals during the oral cleaning operation. The target sound can be speech, music, etc. Furthermore, the oral cleaning device can generate a first drive signal based on configured cleaning parameters, input the first drive signal to the first drive unit, obtain audio data to be output, generate a second drive signal based on the audio data at intervals of a first duration, and input the second drive signal to the second drive unit.

[0106] The output shaft can perform a second movement at a first time interval to generate a target sound. The first time interval can be set according to actual needs, such as 10 seconds, 30 seconds, 45 seconds, etc., but is not limited thereto. By generating a target sound at a fixed time interval, the target sound can optionally be used to inform the user of the cleaning progress. The user can accurately know the current cleaning progress through the target sound generated by the oral cleaning device, further improving the user experience.

[0107] For example, Figure 3B FIG. 1 is a schematic diagram of the output shaft performing the first motion and the second motion in another embodiment. Figure 3A As shown, referring to the motion curve 330 of the first motion and the motion curve 340 of the second motion, the output shaft of the motor may perform the second motion at intervals of the first time length t1 during the first motion, thereby generating the target sound intermittently while driving the cleaning element to perform the cleaning operation.

[0108] In an embodiment of the present application, the oral cleaning device can generate a target sound at first intervals during the cleaning operation, thereby helping the user better understand the current cleaning progress and further improving the user experience. Furthermore, because the first and second movements of the output shaft do not interfere with each other, the generated musical sound does not affect the cleaning operation. The first movement of the output shaft can continuously drive the cleaning element to perform the cleaning operation without causing any interruption to the user, thereby improving the cleaning effect of the oral cleaning device.

[0109] like Figure 4 As shown, in one embodiment, the step of inputting the second driving signal to the second driving unit may include the following steps:

[0110] Step 402: When the audio output condition is met, input a second driving signal to the second driving unit.

[0111] In some embodiments, the audio output condition may be a condition that requires prompting the user, and one or more audio output conditions may be pre-set. The audio output condition may be uniformly set by the oral cleaning device before leaving the factory, or may be set by the user according to his or her own needs.

[0112] Optionally, the user can set audio output conditions on the oral cleaning device. The oral cleaning device may include a display device that displays a condition setting interface on which the user can set one or more audio output conditions. The oral cleaning device may save the one or more audio output conditions set by the user.

[0113] Optionally, the user may also make settings on a terminal device, which may include but is not limited to a mobile phone, a tablet, a smart wearable device, a central control device for the oral cleaning device, etc. The terminal device may establish a communication connection with the oral cleaning device (such as a Bluetooth connection, a Wi-Fi connection, etc., but not limited thereto), and the terminal device may display a condition setting interface, where the user may set one or more audio output conditions. The terminal device may send the one or more audio output conditions set by the user to the oral cleaning device, so that the oral cleaning device saves the one or more audio output conditions set by the user.

[0114] In some embodiments, the audio output conditions may include, but are not limited to, one or more of a power-on reminder, a low-battery reminder, a cleaning component replacement reminder, an oral region switching reminder, and an overpressure reminder. The power-on reminder condition may refer to detecting that the oral cleaning device is powered on; the low-battery reminder condition may refer to detecting that the remaining battery level of the oral cleaning device is lower than a battery threshold; the cleaning component replacement reminder condition may refer to detecting that the usage time of the cleaning component exceeds a target time; the oral region switching reminder condition may refer to detecting that the cleaning component switches between oral regions in the oral cavity; and the overpressure reminder condition may refer to detecting that the pressure value of the cleaning component is higher than a pressure threshold.

[0115] In one embodiment, the oral cleaning device may obtain device information for detecting the oral cleaning device and determine whether audio output conditions are met based on the device information. The device information may refer to information reflecting the operation and working status of the oral cleaning device. Optionally, the device information may include, but is not limited to, operating information and real-time detection information of the oral cleaning device. The operating information may include, but is not limited to, information such as the oral cleaning device being turned on / off, the operating mode of the oral cleaning device, parameter settings, and whether oral care operations are being performed.

[0116] Real-time detection information may refer to real-time information detected by the oral cleaning device through a sensor. The oral cleaning device may be provided with one or more sensors, and real-time detection information may be collected by the one or more sensors. The real-time detection information may be used to reflect the real-time status of the oral cleaning device. Optionally, the one or more sensors may include, but are not limited to, one or more of a pressure sensor, a posture sensor, a motion sensor, a camera, a photoelectric sensor, a touch piece, etc. The real-time detection information may include, but is not limited to, one or more of the pressure value of the cleaning piece, the posture of the oral cleaning device, the motion information of the oral cleaning device, the status of the touch piece, a facial image, an oral cavity image, etc.

[0117] For example, during the oral cleaning operation of the oral cavity by the oral cleaning device, the pressure value of the cleaning member can be detected by the pressure sensor, and it can be determined whether the pressure value of the cleaning member is greater than the pressure threshold. If the pressure value of the cleaning member is greater than the pressure threshold, it is determined that the overpressure warning condition is met.

[0118] Exemplarily, when the oral cleaning device obtains a power-on instruction (for example, the user presses a power-on button on the oral cleaning device to trigger generation of a power-on instruction), it is determined that the power-on reminder condition is met.

[0119] For example, the motion information of the oral cleaning device can be collected through posture sensors and motion sensors (such as acceleration sensors, speed sensors, etc.) to determine whether the oral area of the oral cleaning device has changed. If it is determined based on the motion information of the oral cleaning device that the oral area where the cleaning part is located has changed, it is determined that the oral area switching reminder conditions are met.

[0120] By utilizing the detected device information of the oral cleaning device, it is possible to accurately determine whether the audio output condition is met, thereby accurately controlling the output shaft of the motor to perform the second movement to produce the desired target sound.

[0121] In some embodiments, different audio output conditions may correspond to different audio data. That is, when the oral cleaning device satisfies different audio output conditions, the oral cleaning device may produce different target sounds. When the audio output conditions are met, the audio data corresponding to the satisfied audio output conditions may be obtained as the audio data to be output, and a second drive signal may be generated based on the audio data to be output, and the second drive signal may be input to the second drive unit.

[0122] If the audio output condition is determined to be met, the controller of the oral cleaning device may obtain audio data corresponding to the met audio output condition. The audio data corresponding to the audio output condition may be a prompt voice or a prompt music. The audio data corresponding to the currently met audio output condition may be processed, such as by digital-to-analog conversion and power amplification, to generate a second drive signal. The second drive signal is input to the second drive unit. The second drive unit may drive the output shaft to perform a second motion based on the second drive signal and generate a target sound corresponding to the met audio output condition.

[0123] For example, if the power-on prompt conditions are met, the audio data of the power-on music can be obtained as the audio data to be output, and a second drive signal can be generated based on the audio data of the power-on music and input into the second drive unit so that the second drive unit drives the output shaft to perform a second movement to produce the sound of the power-on music.

[0124] Exemplarily, if the low battery reminder condition is met, the audio data of the battery reminder voice can be obtained as the audio data to be output, and a second drive signal is generated based on the audio data of the battery reminder voice and input into the second drive unit so that the second drive unit drives the output shaft to perform a second movement to produce the sound of the battery reminder voice.

[0125] In an embodiment of the present application, the output shaft of the motor can be controlled to produce different target sounds for different audio output conditions to meet the sound playback requirements of the oral cleaning device in different scenarios, thereby improving the richness of the sound played by the oral cleaning device.

[0126] In an embodiment of the present application, if the audio output conditions are met, the motor's output shaft can be controlled to perform a second motion to produce a target sound. This can meet the oral cleaning device's need to output voice prompts or music prompts in different scenarios. Furthermore, the first and second motions of the output shaft do not interfere with each other, and the sound produced does not affect the cleaning operation, thereby ensuring the cleaning effect of the oral cleaning device. Furthermore, if the audio output conditions are not met, the second drive unit can be disabled, thereby reducing the power consumption of the oral cleaning device.

[0127] In some embodiments, the amplitude of the first movement performed by the output shaft may be greater than the amplitude of the second movement; and / or the frequency of the first movement performed by the output shaft may be greater than the frequency of the second movement.

[0128] The oral cleaning device can control the output shaft to perform a first movement with a larger movement amplitude and / or movement frequency, and drive the cleaning member to perform a cleaning operation through the first movement, which can ensure that the cleaning member cleans the oral cavity with a larger range and / or higher frequency, thereby improving the cleaning effect of the oral cleaning device.

[0129] In some embodiments, when the output shaft performs the first motion and the second motion simultaneously, the motion trajectory of the cleaning member projected onto the target surface may be a curved trajectory.

[0130] Among them, the target surface may include the tooth surface of the teeth. When the output shaft of the motor performs the first motion and the second motion at the same time, the motion trajectory of the cleaning piece on the tooth surface may be a curved trajectory, which can simulate the way a user moves the oral cleaning device while shaking the oral cleaning device up and down when manually performing care operations. For example, it can simulate the brushing technique of a user moving the toothbrush while shaking the bristles of the toothbrush up and down when brushing his teeth manually, which can have a better cleaning effect on the oral cavity.

[0131] Optionally, the target surface may also be other surfaces, for example, a plane tangent to the tooth surface, etc., which is not limited here.

[0132] For example, Figure 5 FIG. 1 is a schematic diagram of the motion trajectory of a cleaning member projected onto a target surface in one embodiment. Figure 5 As shown, taking the oral cleaning device as a toothbrush and the cleaning element as a brush head as an example, the first movement of the output shaft of the toothbrush motor can be a reciprocating rotational movement, and the second movement of the output shaft can be a telescopic movement. The output shaft of the motor can perform telescopic movement and reciprocating rotational movement at the same time, thereby driving the cleaning element to perform lateral telescopic movement and reciprocating rotational movement in a nearly vertical direction. The movement trajectory 510 of the brush head on the tooth surface 520 is a curved trajectory.

[0133] In some embodiments, the curved trajectory projected by the cleaning member onto the target surface may include but is not limited to any one of a circular arc trajectory, a sinusoidal curve trajectory, a spiral curve trajectory, a spring-shaped curve trajectory, and a figure-8 curve trajectory.

[0134] The trajectory state of the curved trajectory can be determined by the motion parameters of the first motion and the second motion performed by the output shaft of the motor, for example, the motion amplitude and motion frequency of the telescopic motion performed by the output shaft of the motor, and the motion amplitude and motion frequency of the reciprocating rotation motion performed by the output shaft of the motor.

[0135] As an embodiment, the frequency of the telescopic motion may be less than the frequency of the reciprocating rotational motion. When the frequency of the telescopic motion of the motor's output shaft is less than the frequency of the reciprocating rotational motion, the combined telescopic and reciprocating rotational motions of the output shaft can drive the cleaning element to form a sinusoidal, spiral, or spring-like trajectory, which can better simulate the user's manual control of the oral cleaning device for oral care operations, similar to moving the oral cleaning device while shaking it up and down, effectively removing dental plaque and achieving a better cleaning effect on the oral cavity.

[0136] Furthermore, the frequency of the reciprocating rotational motion may be greater than or equal to twice the frequency of the telescopic motion, which may more accurately simulate the user's manual toothbrushing technique.

[0137] In an embodiment of the present application, the output shaft of the motor performs the first motion and the second motion simultaneously, and the cleaning member can form any curved trajectory such as a circular arc trajectory, a sinusoidal curve trajectory, a spiral curve trajectory, a spring-shaped curve trajectory, and a figure-8 curve trajectory on the target surface, which can achieve a better cleaning effect, avoid damaging the gums, and protect oral health.

[0138] In some embodiments, the amplitude of the second movement performed by the output shaft of the motor may be greater than the amplitude threshold. The amplitude of the second movement performed by the output shaft is large, which can ensure the combined movement of the first movement and the second movement performed by the output shaft, and can drive the cleaning element to move along a curved trajectory to achieve multi-angle cleaning, further improving the cleaning effect of the oral cleaning equipment.

[0139] Moreover, when it is necessary to output the target sound, the frequency of the second movement of the output shaft of the motor can change with the frequency of the audio signal, so that the combined movement of the second movement and the first movement can drive the cleaning element to form a richer and more diverse movement trajectory, further improving the cleaning effect of the oral cleaning device.

[0140] In some embodiments, when there is no need to output the target sound, the oral cleaning device can also generate a third drive signal according to the configured cleaning parameters, and input the third drive signal to the second drive unit, so that the second drive unit drives the output shaft to perform a second movement based on the third drive signal. The first movement and the second movement can jointly drive the cleaning element to perform a cleaning operation on the oral cavity.

[0141] The third drive signal may be a drive signal having a certain regularity, and the second motion of the output shaft driven by the second drive unit based on the third drive signal may be a regular motion. Furthermore, the third drive signal may include a pulse signal, and the oral cleaning device may generate the first drive signal according to configured cleaning parameters. The configured cleaning parameters may include motion parameters corresponding to the first motion and motion parameters corresponding to the second motion, such as the motion amplitude, motion frequency, and motion strength of the first motion, and the motion amplitude, motion frequency, and motion strength of the second motion.

[0142] A first drive signal can be generated according to the motion parameters of the first motion, and a third drive signal can be generated according to the motion parameters of the second motion, and the first drive signal can be input to the first drive unit and the third drive signal can be input to the second drive unit at the same time, so that the output shaft of the motor driven by the first drive unit performs the first motion, and the output shaft of the motor driven by the second drive unit performs the second motion. The first motion and the second motion will not interfere with each other, and the two motions can produce better synergy to achieve better cleaning effect.

[0143] In an embodiment of the present application, the amplitude of the second movement performed by the output shaft of the motor may be greater than the amplitude threshold, and the combined movement of the first movement and the second movement performed by the output shaft can effectively remove dental plaque in the oral cavity, etc., and can improve the cleaning effect of the oral cleaning device.

[0144] like Figure 6 As shown, in one embodiment, a control device 600 for an oral cleaning device is provided, which can be applied to the above-mentioned oral cleaning device. The control device 600 for the oral cleaning device can include a first motion module 610 and a second motion module 620 .

[0145] The first motion module 610 is used to input a first driving signal to the first driving unit so that the first driving unit drives the output shaft to perform a first motion based on the first driving signal. The first motion is used to enable the oral cleaning device to perform a cleaning operation on the oral cavity.

[0146] The second motion module 620 is configured to input a second driving signal to the second driving unit so that the second driving unit drives the output shaft to perform a second motion based on the second driving signal. The second motion can generate a target sound. The first motion is different from the second motion.

[0147] In one embodiment, the amplitude of the first movement is greater than the amplitude of the second movement; and / or the frequency of the first movement is greater than the frequency of the second movement.

[0148] In one embodiment, the first driving signal comprises a pulse signal, and the second driving signal comprises an audio signal.

[0149] The first motion module 610 is further configured to generate a first driving signal according to the configured cleaning parameters and input the first driving signal to the first driving unit.

[0151] In one embodiment, the second motion module 620 is further configured to input a second driving signal to the second driving unit simultaneously during the process of inputting the first driving signal to the first driving unit.

[0152] In one embodiment, the second motion module 620 is further configured to input a second driving signal to the second driving unit at intervals of a first duration during the process of inputting the first driving signal to the first driving unit.

[0153] In one embodiment, the second motion module 620 is further configured to input a second driving signal to the second driving unit when the audio output condition is met.

[0154] In one embodiment, the second motion module 620 is further used to obtain audio data corresponding to the satisfied audio output condition as audio data to be output when the audio output condition is met; generate a second driving signal according to the audio data to be output, and input the second driving signal to the second driving unit.

[0155] In one embodiment, the oral cleaning device further comprises a cleaning member, and the motor is used to drive the cleaning member to move; the distance between the second driving unit and the cleaning member is smaller than the distance between the first driving unit and the cleaning member.

[0156] In one embodiment, the driving power of the first driving unit is greater than the driving power of the second driving unit.

[0157] In one embodiment, the direction of movement of the first movement is different from the direction of movement of the second movement.

[0158] In one embodiment, the oral cleaning device also includes a cleaning member, the output shaft is connected to the cleaning member, and the motor is used to drive the cleaning member to move; when the output shaft performs the first movement and the second movement at the same time, the motion trajectory of the cleaning member projected onto the target surface is a curved trajectory.

[0159] In one embodiment, the curved trajectory includes any one of a circular arc trajectory, a sinusoidal curve trajectory, a spiral curve trajectory, a spring-shaped curve trajectory, and a figure-8 curve trajectory.

[0160] In one embodiment, the motion amplitude of the second motion is greater than the amplitude threshold.

[0161] In an embodiment of the present application, the two drive units of the motor can be controlled separately, one drive unit is used to drive the output shaft to perform a first movement to achieve a cleaning operation, and the other drive unit is used to drive the output shaft to perform a second movement to generate a target sound. This can reduce the control interference between the two movements, so that the motor will not affect the cleaning operation of the oral cavity while generating the target sound, thereby ensuring the cleaning effect of the oral cleaning equipment.
