Description

Technical Field

[0001] The present application relates to the field of oral care technology, and in particular to a control method and device for oral care equipment and oral care equipment. Background Art

[0002] With the development of electronic technology and users' increasing attention to oral health, more and more electric oral care devices have appeared on the market, such as electric toothbrushes, water flossers, etc., which can help users better clean and care for their oral cavity and improve their oral health.

[0003] Currently, electric oral care devices are prone to splashing of water, foam or cleaning liquid during use, affecting the user experience. Summary of the Invention

[0004] The embodiments of the present application disclose a control method, device and oral care device for oral care equipment, which can reduce the splashing of water, foam or cleaning liquid during the use of the oral care equipment and improve the user experience.

[0005] The present application discloses a control method for an oral care device, which is applied to the oral care device. The oral care device includes a motor having an output shaft, the motor including a first drive unit and a second drive unit, the first drive unit being used to drive the output shaft to perform telescopic motion, and the second drive unit being used to drive the output shaft to perform reciprocating rotational motion. The method includes:

[0006] If it is detected that the oral care device switches from a first state to a second state, obtaining a first target operating parameter corresponding to the telescopic motion and the second state, and obtaining a second target operating parameter corresponding to the reciprocating rotation motion and the second state;

[0007] gradually adjusting an operating parameter corresponding to the telescopic motion from a first initial operating parameter to a first target operating parameter, and controlling the first driving unit to drive the output shaft to perform the telescopic motion based on the first target operating parameter;

[0008] The operating parameters corresponding to the reciprocating rotational motion are gradually adjusted from the second initial operating parameters to the second target operating parameters, and based on the second target operating parameters, the second driving unit is controlled to drive the output shaft to perform the reciprocating rotational motion.

[0009] In this embodiment, a motor for an oral care device has an output shaft and includes a first drive unit and a second drive unit. The first drive unit is configured to drive the output shaft to perform telescopic motion, and the second drive unit is configured to drive the output shaft to perform reciprocating rotational motion. When it is detected that the oral care device switches from a first state to a second state, a first target operating parameter corresponding to the telescopic motion and the second state is obtained, and a second target operating parameter corresponding to the reciprocating rotational motion and the second state is obtained. The operating parameter corresponding to the telescopic motion is gradually adjusted from a first initial operating parameter to the first target operating parameter. Based on the first target operating parameter, the first drive unit is controlled to drive the output shaft to perform telescopic motion, and the operating parameter corresponding to the reciprocating rotational motion is gradually adjusted from a second initial operating parameter to a second target operating parameter. Based on the second target operating parameter, the second drive unit is controlled to drive the output shaft to perform reciprocating rotational motion. When the oral care device switches states, the operating parameters corresponding to the telescopic motion and the reciprocating rotational motion of the motor output shaft can be gradually adjusted, resulting in a smoother change in the operating parameters. This can prevent splashing of water, foam, or cleaning liquid from the oral care device due to sudden changes in the operating parameters of the telescopic motion or the reciprocating rotational motion, thereby improving the user experience.

[0010] As an optional embodiment, the oral care device also includes a care piece, the output shaft is connected to the care piece, and the motor is used to drive the care piece to move; when the output shaft simultaneously performs the telescopic motion and the reciprocating rotation motion, the motion trajectory of the care piece projected onto the target surface is a curved trajectory.

[0011] In this embodiment, when the output shaft of the motor performs telescopic motion and reciprocating rotation motion at the same time, the motion trajectory of the care part projected onto the target surface is a curved trajectory, which can simulate the way a user holds the oral care device in hand and shakes the oral care device up and down while performing manual care operations, thereby having a better cleaning effect on the oral cavity.

[0012] As an optional implementation, 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.

[0013] In this embodiment, the output shaft of the motor performs a combination of telescopic motion and reciprocating rotational motion, and the care part can form any curved trajectory such as an arc trajectory, a sinusoidal curve trajectory, a spiral curve trajectory, a spring-shaped curve trajectory, a figure-8 curve trajectory, etc. on the target surface, which can achieve better cleaning effects, avoid damaging the gums, and protect oral health.

[0014] As an optional embodiment, in the process of gradually adjusting the operating parameters corresponding to the telescopic motion from the first initial operating parameters to the first target operating parameters, and gradually adjusting the operating parameters corresponding to the reciprocating rotational motion from the second initial operating parameters to the second target operating parameters, the trajectory type of the motion trajectory of the nursing part projected onto the target surface remains unchanged, and the trajectory range of the motion trajectory of the nursing part projected onto the target surface becomes larger or smaller.

[0015] In this embodiment, the trajectory shape will not change significantly, only the trajectory range of the motion trajectory will become larger or smaller, which can further reduce the splashing of water, foam or cleaning liquid in the oral care device.

[0016] As an optional implementation manner, the parameter type corresponding to the first target operating parameter is the same as the parameter type corresponding to the second target operating parameter.

[0017] As an optional implementation, the parameter type includes one or more of movement frequency, movement amplitude, and movement strength.

[0018] In this embodiment, by gradually adjusting the operating parameters of the same parameter type for the telescopic motion and reciprocating rotational motion of the output shaft of the motor, it can be ensured that the trajectory shape of the motion trajectory of the care part projected onto the target surface will not change significantly, which can further reduce the splashing of water, foam or cleaning liquid during the use of the oral care device, thereby improving the user experience.

[0019] As an optional implementation manner, gradually adjusting the operating parameter corresponding to the telescopic movement from the first initial operating parameter to the first target operating parameter includes:

[0020] Within a first time period, gradually adjusting the operating parameter corresponding to the telescopic movement from a first initial operating parameter to the first target operating parameter;

[0021] The step of gradually adjusting the operating parameter corresponding to the reciprocating rotational motion from the second initial operating parameter to the second target operating parameter includes:

[0022] During the first time period, the operating parameter corresponding to the reciprocating rotational motion is synchronously and gradually adjusted from the second initial operating parameter to the second target operating parameter.

[0023] In this embodiment, the operating parameters of the telescopic motion and the operating parameters of the reciprocating rotational motion can be gradually adjusted synchronously, so that the changes in the operating parameters are smoother. While avoiding sudden changes in the throwing force of the oral care device, the trajectory shape of the motion trajectory of the care part on the target surface can also remain basically unchanged, thereby further reducing the splashing of water, foam or cleaning liquid in the oral care device and improving the user experience.

[0024] As an optional embodiment, the changing trend of the operating parameters corresponding to the telescopic motion from the first initial operating parameters to the first target operating parameters is the same as the changing trend of the operating parameters corresponding to the reciprocating rotational motion from the second initial operating parameters to the second target operating parameters.

[0025] In this embodiment, the changing trends of the operating parameters of the telescopic motion and the reciprocating rotational motion are the same, which can further ensure that the trajectory shape of the motion trajectory of the care part projected onto the target surface will not change greatly, and can further reduce the splashing of water, foam or cleaning liquid during the use of the oral care device, thereby improving the user experience.

[0026] As an optional implementation manner, the first state includes a stopped working state, and the second state includes a started working state; and / or,

[0027] The first state includes the oral care device operating in a first working mode, and the second state includes the oral care device operating in a second working mode; and / or,

[0028] The first state includes the oral care device corresponding to a first parameter gear, and the second state includes the oral care device corresponding to a second parameter gear; and / or,

[0029] The first state includes the oral care device being in a first oral region, and the second state includes the oral care device being in a second oral region; and / or,

[0030] The first state includes a state in which the oral care device is outside the oral cavity, and the second state includes a state in which the oral care device is inside the oral cavity.

[0031] In this embodiment, when the state of the oral care device is switched, the operating parameters of the telescopic motion and the reciprocating rotational motion of the output shaft of the motor can be gradually adjusted, so as to avoid sudden changes in the throwing force of the oral care device during the state switching process, which may cause splashing of water, foam or cleaning liquid in the oral care device.

[0032] As an optional embodiment, the movement frequency corresponding to the telescopic movement is the same as the movement frequency corresponding to the reciprocating rotational movement; or,

[0033] The movement frequency corresponding to the telescopic movement is smaller than the movement frequency corresponding to the reciprocating rotational movement.

[0034] In this embodiment, the telescopic motion has the same frequency as the reciprocating rotational motion, the method of controlling the motor motion is relatively simple, and can allow the care part to form a relatively rounded curved trajectory, thereby improving the protective effect and cleaning effect of the oral care device on the oral cavity; or, the telescopic motion has a lower frequency than the reciprocating rotational motion, which can better simulate the user's manual control of the oral care device for oral care operations, similar to moving the oral care device while shaking the oral care device up and down, which can better remove dental plaque, etc., and has a better cleaning effect on the oral cavity.

[0035] As an optional implementation, the method further includes:

[0036] Controlling the output shaft of the motor to alternately perform a target combined motion and a target unidirectional motion; the target combined motion is a combination of the telescopic motion and the reciprocating rotational motion, and the target unidirectional motion is the telescopic motion or the reciprocating rotational motion;

[0037] In the first sub-period of each alternating cycle, the output shaft performs the telescopic motion and the reciprocating rotation motion simultaneously; in the second sub-period of the alternating cycle, the output shaft performs the telescopic motion or the reciprocating rotation motion.

[0038] In this embodiment, the output shaft of the motor can be controlled to alternately perform target combined motion and target unidirectional motion, and the output shaft alternately performs target combined motion and target unidirectional motion, which increases the richness of the motion trajectory of the care parts during oral care operations, can clean the oral cavity more comprehensively, and can further improve the cleaning effect of the oral care equipment.

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 telescopic motion, and the second drive unit is used to drive the output shaft to perform reciprocating rotational motion. The device includes:

[0060] 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.

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.

[0063] Figure 1A FIG. 1 is an application scenario diagram of a control method for an oral care device in one embodiment. Figure 1A As shown, the control method of the oral care device disclosed in the embodiment of the present application can be applied to the oral care device 100, and the oral care device 100 may include but is not limited to an electric toothbrush, an oral irrigator, etc.

[0064] In some embodiments, the oral care device 100 may include a care piece 110 and a handle 120, and the care piece 110 is detachably connected to the handle 120. Taking the oral care device 100 as an electric toothbrush as an example, the care piece may be a brush head, which may be composed of a brush rod and bristles.

[0065] In some embodiments, the handle 120 of the oral care device 100 may be provided with a motor. During operation of the oral care device 100, the motor may be controlled to drive the care element 110 to move, thereby performing a care operation on the oral cavity, thereby realizing the oral care function of the oral care device 100. For example, if the oral care device 100 is an electric toothbrush, the motor may drive the brush head to move, thereby performing a brushing operation on the oral cavity.

[0066] Furthermore, the oral care device 100 may be provided with a controller, which may be used to control the operation of the motor.

[0067] 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 care component 110. When the output shaft 132 moves, the care component 110 may be driven to move.

[0068] 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 used to drive the output shaft 132 to perform telescopic motion, and the second drive unit 136 may be used to drive the output shaft 132 to perform reciprocating rotational motion.

[0069] The output shaft 132's telescopic motion may refer to the output shaft 132 performing reciprocating linear motion along the long axis of the oral care device 100. For example, the direction of the telescopic motion may be indicated by arrow 140. The output shaft 132's reciprocating rotational motion may refer to the output shaft 132 performing reciprocating rotational motion about a reference zero axis. The reference zero axis may be parallel to the long axis of the oral care device 100 or may be an axis at a predetermined angle to the long axis of the oral care device 100, without limitation. For example, the direction of the reciprocating rotational motion may be indicated by arrow 150.

[0070] Optionally, the first drive unit 134 and the second drive unit 136 can be magnetic drive mechanisms, each of which can use the magnetic force generated by the 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 to move, 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, and the two motions can produce a good synergistic effect. Moreover, the first drive unit 134 and the second drive unit 136 share the same output shaft 132, which can make the structure of the motor 130 more compact. The output shaft 132 can be used to more efficiently transmit motion, so that the care piece 110 can better clean the oral cavity and have a better cleaning effect on the oral cavity.

[0071] In the related art, when the state of the oral care device 100 switches, for example, when the oral care device 100 is started (i.e., switched from a stopped working state to a started working state), since the first drive unit 134 and the second drive unit 136 in the motor 130 will be started directly, the operating parameters of the first drive unit 134 and the second drive unit 136 will suddenly increase, causing the throwing force of the oral care device 100 to suddenly increase, causing water, foam or cleaning liquid to splash on the oral care device 100, affecting the user's experience.

[0072] In an embodiment of the present application, if the controller of the oral care device 100 detects that the oral care device 100 has switched from a first state to a second state, it may obtain a first target operating parameter corresponding to the telescopic motion in the second state, and a second target operating parameter corresponding to the reciprocating rotational motion in the second state. The controller of the oral care device 100 may gradually adjust the operating parameter corresponding to the telescopic motion from a first initial operating parameter to the first target operating parameter, and based on the first target operating parameter, control the first drive unit 134 to drive the output shaft 132 to perform telescopic motion. The controller of the oral care device 100 may also gradually adjust the operating parameter corresponding to the reciprocating rotational motion from a second initial operating parameter to a second target operating parameter, and based on the second target operating parameter, control the second drive unit 136 to drive the output shaft 132 to perform reciprocating rotational motion. Because the operating parameters of the telescopic motion and reciprocating rotational motion of the output shaft 132 of the motor 130 change gradually, a sudden change in the throwing force of the oral care device 100 is avoided, thereby reducing splashing of water, foam, or cleaning liquid from the oral care device 100 and improving the user experience.

[0073] It should be noted that Figure 1B It 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.

[0074] like Figure 2 As shown, in one embodiment, a control method for an oral care device is provided. The method can be applied to the above-mentioned oral care device, and the method may include the following steps:

[0075] Step 210 : If it is detected that the oral care device switches from the first state to the second state, obtain first target operating parameters corresponding to the telescopic motion and the second state, and obtain second target operating parameters corresponding to the reciprocating rotation motion and the second state.

[0076] The oral care device may have a variety of different states, which may include but are not limited to the working state of the oral care device, the working mode of the oral care device, the parameter level of the oral care device, the oral position of the oral care device, etc.

[0077] In some embodiments, the working status of the oral care device can be used to describe whether the oral care device is performing oral care operations. The working status of the oral care device may include but is not limited to a stopped working state, a started working state, a working state, etc.

[0078] Among them, the stopped working state may refer to a state in which the oral care device does not perform oral care operations. For example, the stopped working state may be a state in which work is suspended, a state in which the oral care operation is ended, or a state in which the oral care device is awakened but the oral care operation has not yet started.

[0079] The startup working state may refer to the state in which the oral care device is started to perform an oral care operation. Optionally, the startup working state may be triggered by a startup instruction, and when the startup instruction is obtained, the oral care device is controlled to start performing an oral care operation. As an embodiment, the startup instruction may be generated by the oral care device when a startup operation is detected. The startup operation may include but is not limited to one or more operations on the touch piece on the oral care device, gesture operations, operations to change the posture of the oral care device, etc. Among them, the touch piece may include but is not limited to a button, etc., and the operation on the touch piece on the oral care device may include but is not limited to the operation of pressing the button (i.e., short pressing the button), the operation of continuously pressing the button on the oral care device (i.e., long pressing the button), etc.

[0080] As another embodiment, the start instruction may also be sent by a terminal device that is communicatively connected to the oral care device. The terminal device may include but is not limited to a mobile phone, a tablet computer, a smart wearable device, a central control device associated with the oral care device, etc. The user may trigger a start operation on the terminal device. The terminal device generates a start instruction based on the detected start operation and sends the start instruction to the oral care device to control the oral care device to start the oral care operation.

[0081] In some embodiments, the oral care device may be pre-configured with multiple operating modes, and different operating modes may enable the oral care device to achieve different oral care effects. For example, taking a toothbrush as an example, the oral care device may be pre-configured with multiple brushing modes, such as a whitening mode, a powerful mode, and a soothing mode. The whitening mode helps whiten the user's teeth, the powerful mode helps the user clean their teeth better, and the soothing mode provides a more comfortable brushing method, suitable for users with sensitive teeth.

[0082] Furthermore, different working modes may correspond to different working parameters and / or movement modes.

[0083] Among them, the operating parameters may refer to the parameters corresponding to the oral care operation performed by the oral care device, which may include but are not limited to parameters such as operation amplitude, operation frequency, and operation force. The operation amplitude can be used to characterize the range of an oral care operation. For example, taking a toothbrush as an example, the operation amplitude can be the amplitude range of a brushing action. The operation frequency can be used to characterize the number of oral care operations performed per unit time. For example, taking a toothbrush as an example, the operation frequency can be the number of brushing actions performed per unit time. The operation force can refer to the force generated by the oral care operation. For example, taking a toothbrush as an example, the operation force can refer to the brushing force corresponding to the brushing action.

[0084] The motion mode may refer to the motion mode of the output shaft of the motor. For example, the motion mode may include but is not limited to the output shaft only performing telescopic motion, the output shaft only performing reciprocating rotation motion, the output shaft performing a combination of telescopic motion and reciprocating rotation motion, etc.

[0085] As an embodiment, the operating parameters may include operating parameters corresponding to various motions supported by the motor. In different operating modes, different operating parameters may correspond to various motions included in the motion mode of the motor's output shaft. The operating parameters corresponding to the motion may include, but are not limited to, motion amplitude, motion frequency, and motion force. Among them, the motion amplitude of the motor's output shaft may refer to the range within which the motor's output shaft performs the motion; the motion frequency of the motor's output shaft may refer to the number of times the motor's output shaft performs the motion per unit time; and the motion force of the motor's output shaft may refer to the force generated by the motor's output shaft when it moves.

[0086] In some embodiments, the oral care device may be configured with multiple parameter settings, where the operating parameters correspond to different parameter values or parameter value ranges at different parameter settings. For example, the operating parameters may be divided into low, medium, and high settings, where the parameter value of the operating parameter at the high setting may be greater than the parameter value at the medium setting, and vice versa, but the present invention is not limited thereto. Optionally, multiple parameter settings may be set for each operating parameter, or multiple parameter settings may be shared by multiple operating parameters.

[0087] The oral location of an oral care device may refer to the oral location of the care component of the oral care device. This oral location may include the care component being outside the oral cavity as well as the care component being inside the oral cavity. Furthermore, when the care component is inside the oral cavity, the oral location of the care component may be the oral region where the care component is located. Optionally, the oral region may include, but is not limited to, the tooth region and / or tooth surface. The tooth region may include, but is not limited to, the incisor region, the lateral tooth region, the posterior tooth region, etc. The tooth surface may include, but is not limited to, the occlusal surface, the tooth lateral surface, etc. Furthermore, the tooth lateral surface may also include the outer surface and the inner surface of the tooth.

[0088] In some embodiments, the output shaft of the motor can perform a target combined motion of telescopic motion and reciprocating rotational motion. When the oral care device is in different states, the telescopic motion may correspond to different operating parameters, and the reciprocating rotational motion may also correspond to different operating parameters, wherein different operating parameters may refer to different parameter values of at least some of the operating parameters.

[0089] Since the telescopic motion corresponds to different operating parameters and the reciprocating rotation motion corresponds to different operating parameters when the oral care device is in different states, when the state of the oral care device is switched, if the motor is directly controlled to perform telescopic motion and reciprocating rotation motion with the operating parameters of the second state after switching, it will cause a sudden change in the throwing force of the oral care device, causing water, foam or cleaning liquid to splash on the care parts.

[0090] The oral care device can detect whether a state switch has occurred. If it is detected that the oral care device has switched from a first state to a second state, it can be determined that a state switch has occurred. The first state and the second state are different states of the oral care device. Furthermore, the first state and the second state can be different states under the same category. For example, the first state and the second state can be different operating states, different operating modes, different parameter gears, different oral positions, etc., but are not limited thereto.

[0091] When it is determined that the oral care device has switched states, the oral care device can obtain the first target operating parameter corresponding to the telescopic motion and the second state, and obtain the second target operating parameter corresponding to the reciprocating rotational motion and the second state. The first target operating parameter can be the parameter value of the pre-configured operating parameter of the telescopic motion in the second state, and the second target operating parameter can be the parameter value of the pre-configured operating parameter of the reciprocating rotational motion in the second state.

[0092] Optionally, the first target operating parameter may be all operating parameters of the telescopic movement in the second state, or may be part of the operating parameters of the telescopic movement in the second state, and the part of the operating parameters may be operating parameters that need to be gradually adjusted.

[0093] Optionally, the second target operating parameter may be all operating parameters of the reciprocating rotational motion in the second state, or may be part of the operating parameters of the reciprocating rotational motion in the second state, and the part of the operating parameters may be operating parameters that need to be gradually adjusted.

[0094] Step 220 : gradually adjusting the operating parameters corresponding to the telescopic motion from the first initial operating parameters to the first target operating parameters, and based on the first target operating parameters, controlling the first driving unit to drive the output shaft to perform the telescopic motion.

[0095] When the oral care device detects that the first state has switched to the second state, the operating parameters corresponding to the telescopic movement of the output shaft of the motor can be gradually adjusted from the first initial operating parameters to the first target operating parameters, and based on the first target operating parameters, the first drive unit can be controlled to drive the output shaft to perform the telescopic movement. It should be noted that during the process of gradually adjusting the operating parameters corresponding to the telescopic movement of the output shaft of the motor from the first initial operating parameters to the first target operating parameters, the first drive unit can be controlled to drive the output shaft to perform the telescopic movement based on the real-time operating parameters corresponding to the telescopic movement.

[0096] In some embodiments, the first initial operating parameter corresponding to the telescopic motion may be the operating parameter of the telescopic motion in the first state. For example, if the first state is the oral care device operating in the first operating mode, and the second state is the oral care device operating in the second operating mode, then the first initial operating parameter may be the operating parameter of the telescopic motion in the first operating mode, and the first target operating parameter may be the operating parameter of the telescopic motion in the second operating mode. For another example, if the first state is the oral care device in an inoperative state, then the first initial operating parameter may be 0.

[0097] In some embodiments, the first initial operating parameter corresponding to the telescopic movement can also be a pre-set operating parameter corresponding to the telescopic movement. The first initial operating parameter can be a smaller operating parameter, so that the output shaft of the motor starts the telescopic movement with a smaller operating parameter, which can avoid the splashing of water, foam or cleaning liquid in the oral care equipment due to the excessive operating parameters of the telescopic movement at startup.

[0098] The operating parameter corresponding to the telescopic motion is gradually adjusted from the first initial operating parameter to the first target operating parameter, which may include but is not limited to gradually increasing the operating parameter corresponding to the telescopic motion from the first initial operating parameter to the first target operating parameter, or gradually decreasing the operating parameter corresponding to the telescopic motion from the first initial operating parameter to the first target operating parameter. The changing trend of the operating parameter corresponding to the telescopic motion is not limited in the embodiments of the present application.

[0099] When the first initial operating parameter is less than the first target operating parameter, the operating parameter corresponding to the telescopic movement can be gradually increased from the first initial operating parameter to the first target operating parameter. When the first initial operating parameter is greater than the first target operating parameter, the operating parameter corresponding to the telescopic movement can be gradually decreased from the first initial operating parameter to the first target operating parameter. This can avoid splashing of water, foam, or cleaning liquid on the oral care device due to a sudden change in the operating parameters of the telescopic movement, or discomfort to the user due to a sudden change in the operating parameters of the telescopic movement, thereby improving the user experience.

[0100] Optionally, the method of gradually adjusting the operating parameters corresponding to the telescopic movement may include but is not limited to any of the following methods:

[0101] (1) According to a first variation function, the operating parameters corresponding to the telescopic motion are gradually adjusted from the first initial operating parameters to the first target operating parameters.

[0102] The first variation function can be used to describe how the operating parameters of the telescopic motion change over time. The first variation function can be a linear function or a nonlinear function. The function curve corresponding to the first variation function can be continuous. By adjusting the operating parameters of the telescopic motion using the first variation function, the variation process of the operating parameters of the telescopic motion can be made smoother and more natural.

[0103] For example, Figure 3A FIG. 1 is a schematic diagram of gradually adjusting the operating parameters corresponding to the telescopic motion in one embodiment. Figure 3A As shown, taking the movement amplitude of the telescopic movement as an example, the movement amplitude change curve 310 of the telescopic movement can be referred to. When the oral care device switches from the occurring state, the movement amplitude of the telescopic movement of the output shaft of the motor can gradually increase from the movement amplitude 1 to the movement amplitude 2 according to a linear function, and then the movement amplitude 2 can be maintained for the telescopic movement.

[0104] (2) The operating parameters corresponding to the telescopic movement can be gradually adjusted from the first initial operating parameters to the first target operating parameters in a step-by-step adjustment manner.

[0105] Among them, the step-by-step adjustment of the operating parameters corresponding to the telescopic motion can be performed according to a preset first adjustment period and a first adjustment value. The operating parameters corresponding to the telescopic motion are adjusted successively. The first adjustment period may refer to the period duration of each change of the operating parameters of the telescopic motion (which can be understood as the time interval between two adjacent changes). The first adjustment period can be set according to actual needs. For example, the first adjustment period can be 0.5 seconds, 0.8 seconds, 1 second, etc., but is not limited to this. The first adjustment value can refer to the parameter value of each change of the operating parameters of the telescopic motion, such as the parameter value increased each time, or the parameter value decreased each time, etc. The first adjustment value can be set according to actual needs. Taking the motion frequency of the telescopic motion as an example, the first change value can be 20Hz (Hertz), 50Hz, 43Hz, etc., but is not limited to this.

[0106] For example, Figure 3B FIG. 1 is a schematic diagram of gradually adjusting the operating parameters corresponding to the telescopic motion in another embodiment. Figure 3BAs shown, taking the amplitude of telescopic motion as an example, as shown by the variation curve 320 of the amplitude of telescopic motion, when the oral care device switches from the active state, the amplitude of the telescopic motion of the output shaft of the motor can be gradually increased from amplitude 1 to amplitude 2. Optionally, the first adjustment period of each adjustment can be the same, and the amplitude of each increase can also be the same, which can improve the smoothness of the variation of the operating parameters of the telescopic motion.

[0107] Step 230 : gradually adjusting the operating parameters corresponding to the reciprocating rotational motion from the second initial operating parameters to the second target operating parameters, and based on the second target operating parameters, controlling the second driving unit to drive the output shaft to perform reciprocating rotational motion.

[0108] When the oral care device detects that the first state has switched to the second state, it can control the operating parameters corresponding to the reciprocating rotational motion of the output shaft of the motor to gradually adjust from the second initial operating parameters to the second target operating parameters, and control the second drive unit to drive the output shaft to perform reciprocating rotational motion based on the second target operating parameters. It should be noted that during the process of gradually adjusting the operating parameters corresponding to the reciprocating rotational motion of the output shaft of the motor from the second initial operating parameters to the second target operating parameters, the second drive unit can be controlled to drive the output shaft to perform reciprocating rotational motion based on the real-time operating parameters corresponding to the reciprocating rotational motion.

[0109] In some embodiments, the second initial operating parameter corresponding to the reciprocating rotational motion may be the operating parameter of the reciprocating rotational motion in the first state. For example, if the first state is the oral care device operating at a first parameter gear, and the second state is the oral care device operating at a second parameter gear, then the second initial operating parameter may be the operating parameter of the reciprocating rotational motion at the first parameter gear, and the second target operating parameter may be the operating parameter of the reciprocating rotational motion at the second parameter gear. If the first state is the oral care device stopped, then the second initial operating parameter may be 0.

[0110] In some embodiments, the second initial operating parameter corresponding to the reciprocating rotational motion may also be a pre-set operating parameter corresponding to the reciprocating rotational motion. The second initial operating parameter may be a smaller operating parameter, so that the output shaft of the motor starts to perform reciprocating rotational motion with a smaller operating parameter, which can avoid splashing of water, foam or cleaning liquid in the oral care device due to excessive operating parameters of the reciprocating rotational motion at startup.

[0111] The operating parameter corresponding to the reciprocating rotational motion is gradually adjusted from the second initial operating parameter to the second target operating parameter, which may include but is not limited to gradually increasing the operating parameter corresponding to the reciprocating rotational motion from the second initial operating parameter to the second target operating parameter, or gradually decreasing the operating parameter corresponding to the reciprocating rotational motion from the second initial operating parameter to the second target operating parameter. The changing trend of the operating parameter corresponding to the reciprocating rotational motion is not limited in the embodiments of the present application.

[0112] When the second initial operating parameter is less than the second target operating parameter, the operating parameter corresponding to the reciprocating rotational motion may be gradually increased from the second initial operating parameter to the second target operating parameter. When the second initial operating parameter is greater than the second target operating parameter, the operating parameter corresponding to the reciprocating rotational motion may be gradually decreased from the second initial operating parameter to the second target operating parameter. This can avoid splashing of water, foam, or cleaning liquid on the oral care device due to a sudden change in the operating parameter of the reciprocating rotational motion, or discomfort to the user due to a sudden change in the operating parameter of the reciprocating rotational motion, thereby improving the user experience.

[0113] Optionally, the method of gradually adjusting the operating parameters corresponding to the reciprocating rotational motion may include but is not limited to any of the following methods:

[0114] (1) The operating parameters corresponding to the reciprocating rotational motion are gradually adjusted from the second initial operating parameters to the second target operating parameters according to the second variation function.

[0115] The second variation function can be used to describe how the operating parameters of the reciprocating motion change over time. The second variation function can be a linear function or a nonlinear function. The function curve corresponding to the second variation function can be continuous. By adjusting the operating parameters of the reciprocating motion using the second variation function, the variation process of the operating parameters of the reciprocating motion can be made smoother and more natural.

[0116] For example, Figure 3C FIG. 1 is a schematic diagram of gradually adjusting the operating parameters corresponding to the reciprocating rotation motion in one embodiment. Figure 3C As shown, taking the motion frequency of reciprocating rotational motion as an example, the motion frequency change curve 330 of the reciprocating rotational motion can be referred to. When the oral care device switches from the generating state, the motion frequency of the reciprocating rotational motion of the output shaft of the motor can gradually increase from motion frequency 1 to motion frequency 2 according to a nonlinear function, and then the motion frequency 2 can be maintained for reciprocating rotational motion.

[0117] (2) The operating parameters corresponding to the reciprocating rotational motion can be gradually adjusted from the second initial operating parameters to the second target operating parameters in a step-by-step adjustment manner.

[0118] The step-by-step adjustment of the operating parameters corresponding to the reciprocating rotational motion may be performed in accordance with a preset second adjustment period and second adjustment value. The second adjustment period may refer to the duration of each change in the operating parameters of the reciprocating rotational motion. The second adjustment period may be set according to actual needs. Furthermore, the second adjustment period may be the same as or different from the first adjustment period described above, and is not limited here. The second adjustment value may refer to the parameter value of each change in the operating parameters of the reciprocating rotational motion, such as the parameter value increased each time, or the parameter value decreased each time, etc. The second adjustment value may be set according to actual needs.

[0119] For example, Figure 3D FIG. 1 is a schematic diagram of gradually adjusting the operating parameters corresponding to the reciprocating rotational motion in another embodiment. Figure 3D As shown, taking the frequency of the reciprocating rotational motion as an example, as shown by the change curve 340 of the frequency of the reciprocating rotational motion, when the oral care device switches from the generating state, the frequency of the reciprocating rotational motion of the output shaft of the motor can be gradually increased from frequency 1 to frequency 2. Optionally, the second adjustment period of each adjustment can be the same, and the frequency of each increase can also be the same, which can improve the smoothness of the change of the operating parameters of the reciprocating rotational motion.

[0120] In an embodiment of the present application, when the state of the oral care device switches, the operating parameters corresponding to the telescopic motion of the output shaft of the motor and the operating parameters corresponding to the reciprocating rotational motion can be gradually adjusted to make the change of the operating parameters smoother. This can avoid splashing of water, foam or cleaning liquid in the oral care device due to sudden changes in the operating parameters of the telescopic motion or the reciprocating rotational motion, thereby improving the user experience.

[0121] In some embodiments, the motor of the oral care device can drive the care piece to move. When the output shaft of the motor simultaneously performs telescopic motion and reciprocating rotation motion, the motion trajectory of the care piece projected onto the target surface can be a curved trajectory.

[0122] Among them, the target surface may include the tooth surface of the teeth. When the output shaft of the motor performs telescopic motion and reciprocating rotation motion at the same time, the motion trajectory of the care part on the tooth surface may be a curved trajectory, which can simulate the way a user moves the oral care device up and down while manually performing care operations. For example, it can simulate the brushing technique of a user moving the toothbrush and shaking the bristles of the toothbrush up and down while brushing his teeth manually, which can have a better cleaning effect on the oral cavity.

[0123] Optionally, the target surface may also be other surfaces, for example, a plane tangent to the tooth surface, etc., which is not limited here.

[0124] For example, Figure 4 FIG. 1 is a schematic diagram of the motion trajectory of a nursing component projected onto a target surface in one embodiment. Figure 4 As shown, taking the oral care device as a toothbrush and the care part as a brush head as an example, the output shaft of the toothbrush motor can simultaneously perform telescopic motion and reciprocating rotation motion, thereby driving the care part to perform lateral telescopic motion and reciprocating rotation motion in a nearly vertical direction, and the motion trajectory 410 of the brush head on the tooth surface 420 is a curved trajectory.

[0125] In some embodiments, the curved trajectory projected onto the target surface by the care piece 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, a figure-8 curve trajectory, and the like.

[0126] The trajectory state of the curved trajectory can be determined by the operating parameters corresponding to the telescopic motion of the output shaft of the motor and the operating parameters corresponding to the reciprocating rotational motion of the output shaft of the motor. For example, it can be determined by the motion amplitude and motion frequency of the telescopic motion, and the motion amplitude and motion frequency of the reciprocating rotational motion.

[0127] As an optional embodiment, the frequency of the telescopic motion can be the same as the frequency of the reciprocating rotational motion. When the telescopic motion of the motor's output shaft has the same frequency as the reciprocating rotational motion, the combined telescopic and reciprocating rotational motions of the output shaft can drive the care component to form a curved trajectory similar to a figure-eight. This method of controlling the motor's motion is relatively simple and enables the care component to form a relatively smooth curved trajectory, thereby improving the oral care device's protective and cleaning effects on the oral cavity.

[0128] As another optional 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 care component to form a sinusoidal, spiral, or spring-like trajectory, better simulating the user's manual control of the oral care device for oral care operations, similar to moving the oral care device while shaking it up and down, effectively removing dental plaque and achieving a better cleaning effect on the oral cavity.

[0129] 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.

[0130] In an embodiment of the present application, the output shaft of the motor performs a combination of telescopic motion and reciprocating rotational motion, and the care part can form any curved trajectory such as an 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.

[0131] like Figure 5 As shown, in another embodiment, a method for controlling an oral care device is provided, the method may include the following steps:

[0132] Step 502: If it is detected that the oral care device switches from the first state to the second state, obtain first target operating parameters corresponding to the telescopic motion and the second state, and obtain second target operating parameters corresponding to the reciprocating rotation motion and the second state.

[0133] In some embodiments, the oral care device can detect device information of the oral care device and determine whether the oral care device has switched states based on the device information. The device information may refer to information reflecting the operation and working status of the oral care device. Optionally, the device information may include, but is not limited to, operating information and real-time detection information of the oral care device. The operating information may include, but is not limited to, the operating mode of the oral care device, parameter settings, and whether an oral care operation is being performed.

[0134] Real-time detection information may refer to real-time information detected by an oral care device via a sensor. The oral care device may be provided with one or more sensors, which may be used to collect real-time detection information. This real-time detection information can be used to reflect the real-time status of the oral care 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 trigger, and the like. The real-time detection information may include, but is not limited to, one or more of the pressure value of the care piece, the posture of the oral care device, the motion information of the oral care device, the status of the trigger, a facial image, an oral cavity image, and the like.

[0135] For example, during the oral care operation of the oral care device, the oral image inside the oral cavity can be collected by a camera device, and the oral care device can identify and analyze the collected oral image to determine the oral area where the care piece is located; for another example, the pressure value of the care piece can be collected by a pressure sensor, and the pressure value can be used to analyze whether the care piece has entered the oral cavity; for another example, the motion information of the oral care device can be collected by a posture sensor or a motion sensor (such as an acceleration sensor, a speed sensor, etc.) to determine whether the oral area of the oral care device has changed, etc., but is not limited to this.

[0136] Based on the detected device information of the oral care device, the state switching of the oral care device can be identified more promptly and accurately, thereby improving the timeliness of subsequent adjustments to the operating parameters of the telescopic movement and reciprocating rotational movement of the motor's output shaft.

[0137] In some embodiments, the first state includes a stopped working state, and the second state includes a started working state; and / or, the first state includes the oral care device running in a first working mode, and the second state includes the oral care device running in a second working mode; and / or, the first state includes the oral care device corresponding to a first parameter gear, and the second state includes the oral care device corresponding to a second parameter gear; and / or, the first state includes the oral care device being in a first oral area, and the second state includes the oral care device being in a second oral area; and / or, the first state includes the oral care device being outside the oral cavity, and the second state includes the oral care device entering the oral cavity.

[0138] As an embodiment, when the oral care device detects that it has switched from a stopped working state to a started working state, it can control the operating parameters corresponding to the telescopic motion of the output shaft of the motor to gradually increase, and control the operating parameters corresponding to the reciprocating rotational motion of the output shaft of the motor to gradually increase, thereby avoiding the sudden increase in the throwing force of the oral care device during startup, causing splashing of water, foam or cleaning liquid in the oral care device.

[0139] As an embodiment, when the oral care device detects that the working mode is switched from the first working mode to the second working mode, it can control the operating parameters corresponding to the telescopic movement of the output shaft of the motor, and gradually adjust them from the operating parameters corresponding to the first working mode to the operating parameters corresponding to the second working mode, and control the operating parameters corresponding to the reciprocating rotational movement of the output shaft of the motor, and gradually adjust them from the operating parameters corresponding to the first working mode to the operating parameters corresponding to the second working mode, thereby avoiding a sudden change in the throwing force of the oral care device when the working mode is switched, causing splashing of water, foam or cleaning liquid in the oral care device.

[0140] As an embodiment, when the oral care device detects that the parameter gear is switched from the first parameter gear to the second parameter gear, it can control the operating parameters corresponding to the telescopic movement of the output shaft of the motor, and gradually adjust them from the operating parameters corresponding to the first parameter gear to the operating parameters corresponding to the second parameter gear, and control the operating parameters corresponding to the reciprocating rotational movement of the output shaft of the motor, and gradually adjust them from the operating parameters corresponding to the first parameter gear to the operating parameters corresponding to the second parameter gear, thereby avoiding a sudden change in the throwing force of the oral care device when the parameter gear is switched, causing splashing of water, foam or cleaning liquid in the oral care device.

[0141] As an embodiment, when the oral region where the care piece of the oral care device is located changes, the operating parameters of the motor's output shaft will also change accordingly, and different oral regions have different corresponding operating parameters. When it is detected that the oral region is switched from the first oral region to the second oral region, the operating parameters corresponding to the telescopic motion of the motor's output shaft can be controlled to gradually adjust from the operating parameters corresponding to the first oral region to the operating parameters corresponding to the second oral region, and the operating parameters corresponding to the reciprocating rotational motion of the motor can be controlled to gradually adjust from the operating parameters corresponding to the first oral region to the operating parameters corresponding to the second oral region. This can avoid a sudden change in the throwing force of the oral care device when the oral region where the care piece is located is switched, causing splashing of water, foam, or cleaning liquid from the oral care device.

[0142] As an embodiment, when the care piece of the oral care device is outside the oral cavity, the motor may not operate, or the motor may operate at a lower operating parameter. When the oral care device detects that the care piece has entered the oral cavity from outside the oral cavity, the motor may be controlled to start operating, or to operate at a higher operating parameter. The operating parameter corresponding to the telescopic motion of the motor's output shaft may be controlled to gradually increase, and the operating parameter corresponding to the reciprocating rotational motion of the motor's output shaft may be controlled to gradually increase. This can prevent the oral care device's throwing force from suddenly increasing when the care piece enters the oral cavity, causing water, foam, or cleaning liquid to splash from the oral care device.

[0143] It should be noted that the first state and the second state are not limited to the above-mentioned states, but can also be other states. For example, the first state can be a working state, and the second state can be a stopped state; or, the first state can be a state where the oral care device is in the oral cavity, and the second state can be a state where the oral care device is out of the oral cavity, etc.

[0144] Step 504 : gradually adjusting the operating parameters corresponding to the telescopic movement from the first initial operating parameters to the first target operating parameters within the first time period.

[0145] Step 506 : within the first time period, synchronously adjust the operating parameters corresponding to the reciprocating rotational motion from the second initial operating parameters to the second target operating parameters.

[0146] In some embodiments, the operating parameters of the telescopic motion and the operating parameters of the reciprocating rotational motion can be adjusted synchronously. The synchronous adjustment may refer to the time of starting to adjust the operating parameters being consistent and the time of ending to adjust the operating parameters being consistent. The time of ending to adjust the operating parameters may refer to the time when the operating parameters of the telescopic motion are adjusted to the first target operating parameters and the time when the operating parameters of the reciprocating rotational motion are adjusted to the second target operating parameters.

[0147] Within the first time period after detecting that the oral care device has switched states, the operating parameters corresponding to the telescopic movement of the output shaft of the synchronous control motor can be gradually adjusted from the first initial operating parameters to the first target operating parameters, and the operating parameters corresponding to the reciprocating rotational movement of the output shaft of the control motor can be gradually adjusted from the second initial operating parameters to the second target operating parameters.

[0148] The first duration can be set according to actual needs, such as 3 seconds, 2 seconds, 4 seconds, etc. The first duration should not be too long or too short. It can avoid the output shaft of the motor performing telescopic and reciprocating motions with smaller operating parameters for a long time due to the first duration being too long, thereby reducing the cleaning efficiency of the oral care device. It can also avoid the situation where the throwing force of the oral care device changes suddenly due to the first duration being too short, resulting in splashing of water, foam or cleaning liquid.

[0149] In some embodiments, when the output shaft performs telescopic motion and reciprocating rotational motion simultaneously, the motion trajectory of the nursing part projected onto the target surface is a curved trajectory. In the process of gradually adjusting the operating parameters corresponding to the telescopic motion from the first initial operating parameters to the first target operating parameters, and gradually adjusting the operating parameters corresponding to the reciprocating rotational motion from the second initial operating parameters to the second target operating parameters, the trajectory type of the motion trajectory of the nursing part projected onto the target surface remains unchanged, and the trajectory range of the motion trajectory of the nursing part projected onto the target surface becomes larger or smaller.

[0150] Because the operating parameters of the telescopic motion and the reciprocating rotational motion gradually increase or decrease, while causing the different sudden changes in the throwing force of the oral care device, the trajectory type of the motion trajectory of the care piece projected onto the target surface can also remain basically unchanged, where the trajectory type can refer to a circular arc trajectory, a sine curve trajectory, a spiral curve trajectory, a spring curve trajectory, and a figure-eight curve trajectory. For example, before adjusting the operating parameters of the telescopic motion and the reciprocating rotational motion, the motion trajectory of the care piece projected onto the target surface is a figure-eight curve trajectory. During the process of adjusting the operating parameters of the telescopic motion and the reciprocating rotational motion, because the operating parameters of the telescopic motion and the reciprocating rotational motion gradually increase or decrease, the motion trajectory of the care piece projected onto the target surface also basically remains a figure-eight curve trajectory. The trajectory shape will not change significantly, only the trajectory range of the motion trajectory will increase or decrease, which can further reduce the splashing of water, foam, or cleaning liquid on the oral care device.

[0151] For example, Figure 6 Schematic diagram of the change of the motion trajectory of the nursing part projected onto the target surface in one embodiment. Figure 6As shown, motion trajectory 610 is the motion trajectory of the care piece projected onto the target surface before the operating parameters of the telescopic and reciprocating motions are adjusted; motion trajectory 620 is the motion trajectory of the care piece projected onto the target surface during the adjustment process; and motion trajectory 630 is the motion trajectory of the care piece projected onto the target surface after the adjustment. From motion trajectory 610 to motion trajectory 620 and then to motion trajectory 630, the shape of the motion trajectory remains essentially a spring-like curve, with no significant changes, which can further reduce the risk of water, foam, or cleaning liquid splashing from the oral care device.

[0152] Furthermore, the operating parameters of the telescopic motion and the reciprocating rotational motion are adjusted synchronously, which can further ensure that the trajectory shape of the motion trajectory of the care part projected onto the target surface will not change significantly, and can further reduce the splashing of water, foam or cleaning liquid in the oral care equipment.

[0153] Optionally, in the process of adjusting the operating parameters of the telescopic motion and the reciprocating rotational motion, the motion trajectory of the nursing part projected onto the target surface can be increased or decreased in proportion. For example, when only the motion amplitude of the telescopic motion and the reciprocating rotational motion is adjusted without adjusting the motion frequency of the telescopic motion and the reciprocating rotational motion, the motion trajectory of the nursing part projected onto the target surface can be increased or decreased in proportion.

[0154] Optionally, in the process of adjusting the operating parameters of the telescopic motion and the reciprocating rotational motion, the motion trajectory of the nursing part projected onto the target surface may also be enlarged or reduced non-proportionally. For example, when the motion amplitude and motion frequency of the telescopic motion and the reciprocating rotational motion are adjusted at the same time, the trajectory type of the motion trajectory remains basically unchanged, and the motion trajectory does not increase or decrease proportionally.

[0155] In some embodiments, the parameter type corresponding to the first target operating parameter may be the same as the parameter type corresponding to the second target operating parameter. Optionally, the parameter type of the operating parameter may include but is not limited to one or more of movement frequency, movement amplitude, and movement intensity.

[0156] Exemplarily, when the oral care device adjusts the motion frequency of the telescopic motion of the output shaft of the motor from the first initial motion frequency to the first target motion frequency, the oral care device also adjusts the motion frequency of the reciprocating rotational motion of the output shaft of the motor from the second initial motion frequency to the second target motion frequency. Exemplarily, when the oral care device adjusts the motion amplitude of the telescopic motion of the output shaft of the motor from the first initial motion amplitude to the first target motion amplitude, the oral care device also adjusts the motion amplitude of the reciprocating rotational motion of the output shaft of the motor from the second initial motion amplitude to the second target motion amplitude. Exemplarily, when the oral care device adjusts the motion strength of the telescopic motion of the output shaft of the motor from the first initial motion strength to the first target motion strength, the oral care device also adjusts the motion strength of the reciprocating rotational motion of the output shaft of the motor from the second initial motion strength to the second target motion strength.

[0157] By gradually adjusting the operating parameters of the same parameter type for the telescopic motion and reciprocating rotational motion of the motor's output shaft, it can be ensured that the trajectory shape of the motion trajectory of the care part projected onto the target surface will not change significantly, which can further reduce the splashing of water, foam or cleaning liquid during the use of the oral care device, thereby improving the user experience.

[0158] In some embodiments, the changing trend of the operating parameter corresponding to the telescopic motion from the first initial operating parameter to the first target operating parameter may be the same as the changing trend of the operating parameter corresponding to the reciprocating rotation motion from the second initial operating parameter to the second target operating parameter.

[0159] For example, the operating parameters corresponding to the telescopic motion and the operating parameters corresponding to the reciprocating rotational motion are both gradually increased, or the operating parameters corresponding to the telescopic motion and the operating parameters corresponding to the reciprocating rotational motion are both gradually decreased. This can further ensure that the shape of the motion trajectory of the care component projected onto the target surface does not change significantly, further reducing the splashing of water, foam, or cleaning fluid during use of the oral care device, thereby improving the user experience.

[0160] In an embodiment of the present application, the operating parameters of the telescopic motion and the operating parameters of the reciprocating rotational motion can be gradually adjusted synchronously, so that the changes in the operating parameters are smoother. While avoiding sudden changes in the throwing force of the oral care device, the trajectory shape of the motion trajectory of the care part on the target surface can also remain basically unchanged, thereby further reducing the splashing of water, foam or cleaning liquid in the oral care device and improving the user experience.

[0161] like Figure 7 As shown, in some embodiments, the above method further includes the following steps:

[0162] Step 702 , controlling the output shaft of the motor to alternately perform target combined motion and target unidirectional motion; the target combined motion is a combination of telescopic motion and reciprocating rotation motion, and the target unidirectional motion is telescopic motion or reciprocating rotation motion.

[0163] In the first sub-period of each alternating cycle, the output shaft performs telescopic motion and reciprocating rotation motion simultaneously; in the second sub-period of the alternating cycle, the output shaft performs telescopic motion or reciprocating rotation motion.

[0164] The oral care device can control the output shaft of the motor to cyclically alternately perform target combination motion and target unidirectional motion. The cyclically alternating target combination motion and target unidirectional motion may mean that the output shaft of the motor switches back and forth between target combination motion and target unidirectional motion. For example, it can move in a cyclic manner of target combination motion-target unidirectional motion-target combination motion-target unidirectional motion-target combination motion-target unidirectional motion...

[0165] An alternating cycle may be provided, which may refer to the duration of a target combined motion and a target unidirectional motion, or may be understood as the duration of a cycle. The duration of the alternating cycle may be configured according to actual needs and is not limited here.

[0166] Each alternating cycle may include a first sub-cycle and a second sub-cycle. The first sub-cycle may refer to the time period during which the output shaft of the motor performs the target combined motion within the alternating cycle; the second sub-cycle may refer to the time period during which the output shaft of the motor performs the target unidirectional motion within the alternating cycle.

[0167] In the first sub-period of each alternating cycle, the output shaft of the motor can be controlled to simultaneously perform telescopic motion and reciprocating rotational motion. Furthermore, in the first sub-period of each alternating cycle, the first drive unit and the second drive unit can be simultaneously controlled to drive the output shaft to perform telescopic motion and reciprocating rotational motion. In the second sub-period of each alternating cycle, the output shaft of the motor can be controlled to perform only telescopic motion or only reciprocating rotational motion. Furthermore, in the second sub-period of each alternating cycle, only the first drive unit can be controlled to drive the output shaft to perform telescopic motion, or only the second drive unit can be controlled to drive the output shaft to perform reciprocating rotational motion.

[0168] Optionally, the duration corresponding to the first sub-period of each alternating period may be equal to or unequal to the duration corresponding to the second sub-period. For example, the duration corresponding to the first sub-period may be greater than the duration corresponding to the second sub-period, or the duration corresponding to the first sub-period may be less than the duration corresponding to the second sub-period. This embodiment of the present application does not limit this.

This can avoid splashing of water, foam or cleaning liquid in the oral care device due to sudden changes in the operating parameters of the telescopic motion or the reciprocating rotational motion, thereby improving the user experience.
