[0010] When the second controller is in an abnormal state, the first controller controls the second controller to be initialized so that the second controller is adjusted to a normal state;

[0011] The first controller sends display content and a display screen start instruction to the second controller in a normal state through a preset interface, so that the second controller responds to the display screen start instruction, controls the display screen to turn on, and displays the display content through the display screen.

[0012] Optionally, the first controller determines whether the second controller is in an abnormal state based on the operating parameters of the second controller, including: the first controller determines whether the operating parameters are the same as the preset operating parameters; when the operating parameters are the same as the preset operating parameters, the first controller determines that the second controller is in a normal state; when the operating parameters are different from the preset operating parameters, the first controller determines that the second controller is in an abnormal state; wherein the preset operating parameters are the operating parameters of the second controller after initialization when the electric toothbrush is powered on for the first time.

[0013] Optionally, the first controller controls the second controller to initialize so that the second controller is adjusted to a normal state, including: the first controller sends an initialization instruction to the second controller through a preset interface, so that the second controller responds to the initialization instruction and executes a preset initialization program to adjust operating parameters and adjust the second controller to a normal state.

[0014] Optionally, the first controller obtains the operating parameters of the second controller through the preset interface, including: the first controller sends a query instruction to the second controller through the preset interface, so that the second controller responds to the query instruction and feeds back the operating parameters to the first controller through the preset interface.

[0015] Optionally, before the first controller sends a query instruction to the second controller through the preset interface, it also includes: the first controller controls the data transmission direction of the preset interface to switch to the first direction; wherein, when the data transmission direction of the preset interface is the first direction, data is allowed to be transmitted from the first controller to the second controller.

[0016] Optionally, before the second controller responds to the query instruction and feeds back the operating parameters to the first controller through the preset interface, it also includes: the first controller controls the data transmission direction of the preset interface to switch to a second direction; wherein, when the data transmission direction of the preset interface is the second direction, data is allowed to be transmitted from the second controller to the first controller.

[0017] Optionally, when the display screen needs to be turned on, and before the first controller obtains the operating parameters of the second controller through a preset interface, it also includes: when the display screen is in a sleep state, the first controller sends a wake-up instruction to the second controller through the preset interface; the second controller responds to the wake-up instruction and controls the display screen to switch to an activated state.

[0018] Optionally, before the display screen needs to be turned on, the method further includes: the first controller responds to the user's first operation and determines whether the first operation is a preset operation; when the first operation is the preset operation, the first controller determines that the display screen needs to be turned on.

[0019] Optionally, after displaying the content through the display screen, it also includes: the first controller sends a sleep instruction to the second controller in response to the user's second operation, so that the second controller responds to the sleep instruction and controls the display screen to switch to the sleep state; or, the first controller records the duration of no user operation, and when the duration reaches a preset duration, the first controller sends a sleep instruction to the second controller, so that the second controller responds to the sleep instruction and controls the display screen to switch to the sleep state.

[0020] In a second aspect, an embodiment of the present application provides an electric toothbrush, comprising a display screen, a first controller, and a second controller for controlling the display screen for display; wherein the first controller communicates with the second controller through a preset interface, and the first controller is configured to execute the control method of the electric toothbrush as in the first aspect.

[0021] The electric toothbrush and control method thereof provided in the embodiments of the present application can achieve the following technical effects:

[0022] In an embodiment of the present application, an electric toothbrush with a display screen includes a first controller and a second controller, the second controller is used to control the display screen for display, and the first controller can communicate with the second controller through a preset interface. It is understandable that during the use of the electric toothbrush, when the second controller in the electric toothbrush used to control the display screen for display loses power and loses operating parameters, the display screen still needs to be turned on and displayed after it is powered on again. In the case where the electric toothbrush needs to turn on the display screen, the first controller can obtain the operating parameters of the second controller through the preset interface, so as to determine whether the second controller is in an abnormal state according to the operating parameters of the second controller. When the second controller is in an abnormal state, the first controller can control the second controller to initialize so that the second controller is adjusted to a normal state. The first controller can send display content and display screen opening instructions to the second controller in a normal state through the preset interface, so that the second controller responds to the display screen opening instruction, controls the display screen to turn on, and displays the display content normally.

[0023] In this way, in the electric toothbrush provided by the embodiment of the present application, the first controller can monitor the state of the second controller based on the acquired operating parameters of the second controller when the display screen needs to be turned on, so as to control the second controller to reinitialize when the second controller is in an abnormal state, that is, when the display screen has an abnormal display. After the second controller is reinitialized, the display screen can perform the display function normally, thereby ensuring that the display screen can display the display content normally, reducing the phenomenon of abnormal display on the display screen, and thus improving the user's experience of using the electric toothbrush.

It should be understood that the data used in this way can be interchanged where appropriate, so that the embodiments of the embodiments of the present application described here. In addition, the terms "including" and "having" and any variations thereof are intended to cover non-exclusive inclusions.

[0030] Unless otherwise stated, the term "plurality" means two or more.

[0032] The term "and / or" is a description of the association relationship between objects, indicating that three relationships can exist. For example, A and / or B means: A or B, or, A and B.

[0033] The term "correspondence" may refer to an association relationship or a binding relationship. The correspondence between A and B means that there is an association relationship or a binding relationship between A and B.

[0034] In order to be able to understand the features and technical contents of the embodiments of the present application in more detail, the implementation of the embodiments of the present application is described in detail below in conjunction with the accompanying drawings. The attached drawings are for reference only and are not used to limit the embodiments of the present application. In the following technical description, for the convenience of explanation, a full understanding of the disclosed embodiments is provided through multiple details. However, one or more embodiments can still be implemented without these details. In other cases, to simplify the drawings, well-known structures and devices can be simplified for display.

[0035] Since traditional electric toothbrushes can only achieve basic cleaning functions for teeth and cannot meet the personalized needs of users when using electric toothbrushes, in order to improve the user experience of using electric toothbrushes, the relevant technology provides an electric toothbrush with a display screen. In this way, when using the electric toothbrush, the user can understand the operation mode, remaining power, brushing time, etc. of the electric toothbrush through the display screen of the electric toothbrush. The user can also monitor the brushing habits and tooth condition through the display screen of the electric toothbrush and obtain personalized brushing suggestions, thereby meeting the personalized needs of the user.

[0036] However, in the related art, when a user uses an electric toothbrush with a display screen, the electric toothbrush may fall or hit. When the electric toothbrush is subjected to interference such as falling or hitting, it is easy to cause poor contact of the internal circuit of the electric toothbrush or damage of components, causing the display screen chip to lose power. After the display screen chip loses power, the operating parameters will be lost, and after the display screen is powered on again, the display screen chip cannot be initialized correctly, so the display screen will show abnormal display, thereby affecting the user's experience of using the electric toothbrush.

[0037] In view of this, an embodiment of the present application provides an electric toothbrush and a control method thereof.

[0038] Combination Figure 1 As shown, the embodiment of the present application provides an electric toothbrush, including a grip portion 1, a care portion 2 and a display screen 11. The grip portion 1 can be set as an elongated cylinder for the convenience of the user to hold, and the grip portion 1 is used to support and protect other components in the electric toothbrush. The care portion 2 is connected to the grip portion 1, and the care portion 2 is used to clean the user's oral cavity.

[0039] Optionally, a first controller and a second controller are provided in the grip portion 1, and the first controller and the second controller communicate with each other through a preset interface. The first controller is used as a main controller of the electric toothbrush, mainly for controlling the operation of the electric toothbrush. The second controller is used as a driving controller of the display screen 11, for controlling the display screen 11 to display. Of course, the second controller is also controlled by the first controller to realize indirect control of the display screen 11 by the first controller.

[0040] Furthermore, in the embodiment of the present application, the electric toothbrush may be a device having only a teeth cleaning function, or may be a device integrating a teeth cleaning function and a teeth interdental flushing function, which is not specifically limited in the embodiment of the present application. In addition, the first controller and the second controller may be MCU (Micro Control Unit). The preset interface for the first controller and the second controller to communicate may be an SPI interface (Serial Peripheral Interface).

[0041] Optionally, the connection between the gripping portion 1 and the care portion 2 is a detachable connection or a fixed connection. When using the electric toothbrush, the user grasps the gripping portion 1, puts the care portion 2 connected to the gripping portion 1 into the oral cavity, and uses the care portion 2 to clean or care for the oral cavity or teeth. Since the care portion 2 often comes into contact with the teeth during the process of cleaning or caring for the teeth, the care portion 2 is more seriously damaged or worn than the gripping portion 1 during use, and needs to be replaced in time. The gripping portion 1 and the care portion 2 are detachably connected, so that when the care portion 2 needs to be replaced, the gripping portion 1 can be easily separated from the care portion 2, thereby facilitating the replacement of the care portion 2, thereby enhancing the user experience when using the electric toothbrush.

[0042] In the above electric toothbrush, the first controller can obtain the operating parameters of the second controller through the preset interface when the display screen 11 needs to turn on the display, so as to monitor the state of the second controller, and control the second controller to reinitialize when the second controller is in an abnormal state, that is, when the display screen 11 has an abnormal display. After the second controller is reinitialized, the display screen 11 can perform the display function normally, thereby ensuring that the display screen 11 can display the display content normally, reducing the phenomenon of abnormal display of the display screen, and thus improving the user's experience of using the electric toothbrush.

[0043] Based on the electric toothbrush in the above embodiment, the present application embodiment provides a control method for an electric toothbrush. Figure 2 As shown, the method comprises the following steps:

[0044] S21, when the display screen needs to be turned on, the first controller obtains the operating parameters of the second controller through a preset interface.

[0045] In step S21, since the first controller can communicate with the second controller through the preset interface, the first controller can obtain the operating parameters of the second controller through the preset interface. The operating parameters of the second controller include various parameters of the display screen, such as brightness, contrast, response time, size, etc. When the first controller actually obtains the operating parameters of the second controller, it is not necessary to obtain all the operating parameters of the second controller, but only some of the operating parameters.

[0046] In this step, the display screen needs to be turned on in the following cases: when the user is using the electric toothbrush normally, the electric toothbrush can be controlled to run by performing operations on the electric toothbrush (such as holding operations or key operations). When the electric toothbrush is running, the display screen needs to be turned on to display the running information of the electric toothbrush (such as power, time, date, etc.). Also, when the user is using the electric toothbrush normally, the electric toothbrush is accidentally dropped on the ground, causing the electric toothbrush to be hit, causing interference to the second controller of the electric toothbrush, or the display screen cable is loosened after the electric toothbrush is hit, causing the second controller to lose power; when the second controller is powered on again after losing power, the display screen needs to be turned on.

[0047] S22: The first controller determines whether the second controller is in an abnormal state according to the operating parameters of the second controller.

[0048] In step S22, when the operating parameters of the second controller acquired by the first controller are lost or abnormal, it indicates that the second controller is in an abnormal state, and the second controller cannot drive the display screen to display normally.

[0049] S23, when the second controller is in an abnormal state, the first controller controls the second controller to initialize, so that the second controller is adjusted to a normal state.

[0050] In step S23, when the second controller is in an abnormal state, that is, the second controller loses operating parameters or the operating parameters are abnormal, the first controller controls the second controller to initialize, so that the second controller can reinitialize the operating parameters and restore the second controller to a normal state.

[0051] S24, the first controller sends display content and display screen start-up instructions to the second controller in a normal state through a preset interface.

[0052] In step S24, when the second controller is in a normal state, it means that the second controller can drive the display screen to display normally based on the operating parameters. In this way, the first controller can respond to the user's operation of the electric toothbrush, send the content that the user needs to display to the second controller, and send a display screen start instruction to the second controller. Specifically, the first controller can send the display screen start instruction to the control register of the second controller.

[0053] S25, the second controller controls the display screen to turn on in response to the display screen turn-on instruction, and displays the display content through the display screen.

[0054] In step S25, the display screen turn-on instruction may be an instruction to instruct the display screen to turn on the backlight. After the second controller executes the display screen turn-on instruction, it may drive the display screen to turn on the backlight and display the corresponding display content.

[0055] In the embodiment of the present application, it is understandable that during the use of the electric toothbrush, when the second controller in the electric toothbrush used to control the display screen for display loses power and loses operating parameters, the display screen still needs to be turned on and displayed after powering on again. In the case where the electric toothbrush needs to turn on the display screen, the first controller can obtain the operating parameters of the second controller through a preset interface, so as to determine whether the second controller is in an abnormal state based on the operating parameters of the second controller. When the second controller is in an abnormal state, the first controller can control the second controller to initialize so that the second controller is adjusted to a normal state. The first controller can send display content and display screen opening instructions to the second controller in a normal state through the preset interface, so that the second controller responds to the display screen opening instruction, controls the display screen to turn on, and displays the display content normally.

[0056] In this way, in the electric toothbrush provided by the embodiment of the present application, the first controller can monitor the state of the second controller based on the acquired operating parameters of the second controller when the display screen needs to be turned on, so as to control the second controller to reinitialize when the second controller is in an abnormal state, that is, when the display screen has an abnormal display. After the second controller is reinitialized, the display screen can perform the display function normally, thereby ensuring that the display screen can display the display content normally, reducing the phenomenon of abnormal display on the display screen, and thus improving the user's experience of using the electric toothbrush.

[0057] Optionally, in the above step S21, the first controller obtains the operating parameters of the second controller through the preset interface, including: the first controller sends a query instruction to the second controller through the preset interface, so that the second controller responds to the query instruction and feeds back the operating parameters to the first controller through the preset interface.

[0058] In this embodiment, when the first controller obtains the operating parameters of the second controller, the first controller can send a query instruction to the second controller via a preset interface, and the query instruction is used to obtain all or part of the operating parameters of the second controller. After receiving the query, the second controller can respond to the query instruction and feedback the operating parameters to the first controller via the preset interface.

[0059] It should be noted that, when the preset interface is in full-duplex mode, when the first controller and the second controller communicate through the preset interface, two-way communication is allowed, that is, the first controller and the second controller can transmit data at the same time, so that the first controller directly sends a query instruction to the second controller through the preset interface, and the second controller can also directly feedback the operating parameters to the first controller through the preset interface. However, when the preset interface is in half-duplex mode, when the first controller and the second controller communicate through the preset interface, only one-way communication is allowed, that is, at the same time, only the first controller is allowed to transmit data to the second controller or only the second controller is allowed to transmit data to the first controller.

[0060] In this implementation, in the case where the preset interface is in half-duplex mode, before the first controller sends a query instruction to the second controller through the preset interface, the first controller can control the data transmission direction of the preset interface to switch to the first direction, wherein when the data transmission direction of the preset interface is the first direction, data is allowed to be transmitted from the first controller to the second controller. Before the second controller responds to the query instruction and feeds back the operating parameters to the first controller through the preset interface, the first controller controls the data transmission direction of the preset interface to switch to the second direction, wherein when the data transmission direction of the preset interface is the second direction, data is allowed to be transmitted from the second controller to the first controller.

[0061] With this implementation, when the preset interface is in half-duplex mode, the data transmission direction can be adjusted in time when the first controller and the second controller communicate through the preset interface to ensure normal communication between the first controller and the second controller.

[0062] Optionally, in the above step S22, the first controller determines whether the second controller is in an abnormal state according to the operating parameters of the second controller, including: the first controller determines whether the operating parameters are the same as the preset operating parameters. When the operating parameters are the same as the preset operating parameters, the first controller determines that the second controller is in a normal state. When the operating parameters are different from the preset operating parameters, the first controller determines that the second controller is in an abnormal state. The preset operating parameters are the operating parameters of the second controller after initialization when the electric toothbrush is powered on for the first time.

[0063] In this embodiment, when the electric toothbrush is powered on for the first time after production, it will be initialized for the first time. During the initialization, the clock, memory, interface, etc. of the electric toothbrush will be initialized, and the operating parameters of the second controller in the electric toothbrush will also be initialized. In this embodiment, the first controller can compare the current operating parameters of the second controller with the operating parameters when the second controller is initialized for the first time (i.e., the preset operating parameters). When the current operating parameters of the second controller are the same as the preset operating parameters, it means that the current operating parameters of the second controller are normal, i.e., the second controller is in a normal state; when the current operating parameters of the second controller are different from the preset operating parameters, it means that the current operating parameters of the second controller are lost or abnormal, i.e., the second controller is in an abnormal state.

[0064] By adopting this implementation mode, the first controller can determine whether the operating parameters of the second controller are abnormal by acquiring the current operating parameters of the second controller, so as to determine whether the second controller is in an abnormal state, thereby indirectly determining whether the display screen can display normally, so that the first controller can accurately monitor the abnormal situation of the second controller.

[0065] Optionally, in the above step S23, the first controller controls the second controller to initialize so that the second controller is adjusted to a normal state, including: the first controller sends an initialization instruction to the second controller through a preset interface, so that the second controller responds to the initialization instruction and executes a preset initialization program to adjust operating parameters and adjust the second controller to a normal state.

[0066] In this embodiment, an initialization program is preset in the second controller. When the second controller is in an abnormal state, the second controller can respond to an initialization instruction sent by the first controller through a preset interface to execute the preset initialization program, thereby initializing the operating parameters. After the operating parameters of the second controller in the abnormal state are adjusted to the initialization operating parameters, it can be restored to a normal state.

[0067] By adopting this implementation, the first controller can promptly control the second controller to reinitialize when the second controller is abnormal, so that the second controller can be restored to a normal state in time, thereby ensuring that the second controller can normally drive the display screen for display and reducing the phenomenon of abnormal display of the display screen.

[0068] Based on the electric toothbrush of the above embodiment, the present application embodiment also provides another control method of the electric toothbrush. Figure 3 As shown, the method comprises the following steps:

[0069] S31: The first controller determines, in response to a first operation of a user, whether the first operation is a preset operation.

[0070] S32: When the first operation is a preset operation, the first controller determines that the display screen needs to be turned on.

[0071] S33, when the display screen needs to be turned on and is in a dormant state, the first controller sends a wake-up instruction to the second controller through a preset interface.

[0072] S34, the second controller controls the display screen to switch to an activated state in response to the wake-up instruction.

[0073] S35, the first controller obtains the operating parameters of the second controller through a preset interface.

[0074] S36, the first controller determines whether the second controller is in an abnormal state according to the operating parameters of the second controller.

[0075] S37, when the second controller is in an abnormal state, the first controller controls the second controller to be initialized so that the second controller is adjusted to a normal state.

[0076] S38, the first controller sends display content and display screen start-up instructions to the second controller in a normal state through a preset interface.

[0077] S39, the second controller controls the display screen to turn on in response to the display screen turn-on instruction, and displays the display content through the display screen.

[0078] S301: The first controller sends a sleep instruction to the second controller in response to a second operation of the user.

[0079] S302, the first controller records a duration of time during which no user operation is received, and when the duration reaches a preset duration, the first controller sends a sleep instruction to the second controller.

[0080] S303: The second controller controls the display screen to switch to a sleep state in response to the sleep instruction.

[0081] In the embodiment of the present application, the specific implementation of the above steps S35 to S39 has been described in the previous embodiment. The specific implementation and technical effects can be referred to the previous embodiment and will not be repeated here.

[0082] Optionally, in the above steps S31 and S32, during the operation of the electric toothbrush, when the first controller receives the first operation of the user, it can determine whether the first operation is a preset operation. The preset operation refers to an operation that requires turning on the display screen, for example, the operation of the user using the electric toothbrush to clean teeth after the electric toothbrush is turned on, or the operation of the user continuing to use the electric toothbrush to clean teeth after the electric toothbrush falls off, or the operation of the user needing to light up the display screen of the electric toothbrush when interacting with the electric toothbrush, etc. When the first controller determines that the first operation is the above preset operation, the first controller determines that the display screen needs to be turned on. With this implementation, the screen of the electric toothbrush can respond to the needs of the user and display in a timely manner, thereby improving the user's experience of using the electric toothbrush.

[0083] Optionally, in the above steps S33 and S34, in order to save the power of the electric toothbrush, the display screen of the electric toothbrush may be configured with a sleep function, that is, when the display screen of the electric toothbrush does not perform the display function for a long time, the display screen of the electric toothbrush will enter a low power consumption mode. For example, after the electric toothbrush is turned on, if it has not been running for a long time, the display screen can automatically enter a sleep state. In this way, when the display screen needs to be turned on again, it is necessary to wake up the display screen. Specifically, for the display screen in the sleep state, the first controller can send a wake-up instruction to the second controller through a preset interface, so that the second controller responds to the wake-up instruction and controls the display screen to switch to an active state. With this implementation, when the display screen of the electric toothbrush needs to be turned on, the display screen in the sleep state can be woken up in time, thereby improving the user's experience of using the electric toothbrush.

[0084] Optionally, in the above steps S301 to S303, in order to save the power of the electric toothbrush, after the electric toothbrush displays the relevant content through the display screen, the display screen can enter a dormant state. Specifically, when the electric toothbrush displays the display content through the display screen, the first controller can use the following two judgment methods to determine whether the display content has been displayed. In the first judgment method, the first controller can detect whether a second operation input by the user is received, and the second operation refers to the operation of the user controlling the display screen to enter a dormant state. For the second operation, the first controller can directly send a dormant instruction to the second controller to instruct the second controller to control the display screen to enter a dormant state. In the second judgment method, the first controller can detect whether the user's operation of using the electric toothbrush has not been received for a long time, that is, the first controller records the duration of not receiving the user's operation. When the duration reaches the preset duration, it means that the user has not used the electric toothbrush for a long time. At this time, the first controller can send a dormant instruction to the second controller to instruct the second controller to control the display screen to enter a dormant state.

[0085] In this embodiment, the sleep instruction may be an instruction to instruct the second controller to turn off the backlight of the display screen. The preset duration may be 15 seconds.

[0086] By adopting this implementation, when the user does not use the electric toothbrush for a long time, the display screen can be controlled to enter a dormant state, thereby saving power of the electric toothbrush.
