Description

Technical Field

[0001] The present application relates to the technical field of electric toothbrushes, and in particular to an electric toothbrush and a control system, method and storage medium of the electric toothbrush. Background Art

[0002] As the quality of life improves, people pay more and more attention to oral hygiene, and the use of electric toothbrushes is becoming more and more popular. Generally speaking, electric toothbrushes are driven by motors to drive the brush head to rotate or vibrate, thereby achieving the purpose of brushing teeth.

[0003] Usually, electric toothbrushes are controlled by buttons on the surface of the electric toothbrush. The working principle is that after the button sends a signal, the control chip controls the power on and off of the electric toothbrush or switches the brushing mode and operating power of the electric toothbrush according to the signal sent by the button. With the advancement of technology, people want to connect objects with mobile phones so that they can directly control objects through mobile phones to improve the quality of life. In the prior art, the interconnection between a mobile phone and an electric toothbrush has been realized, and the electric toothbrush is controlled by the mobile phone. However, in the prior art, the electric toothbrush is in a turned-off state when not in use. When the electric toothbrush needs to be used, it is still necessary to manually turn on the electric toothbrush and complete the interconnection with the mobile phone before the electric toothbrush can be controlled by the mobile phone. Therefore, the electric toothbrush needs to be manually turned on and interconnected with the mobile phone every time it is used. After the electric toothbrush is turned on, almost all actuators except the motor of the electric toothbrush will enter the working state, and the start or shutdown of the motor is controlled by a button or a mobile phone. At the same time, after the electric toothbrush is used, the electric toothbrush is turned off by a button or a mobile phone, which is relatively cumbersome. At the same time, when the electric toothbrush is turned on but the user does not use the electric toothbrush normally to clean teeth (for the convenience of description, this state is referred to as the standby state below), only the motor does not enter the working state, and the remaining actuators will enter the working state. Therefore, the electric toothbrush will continue to consume power in the standby state, greatly reducing the battery life of the electric toothbrush.

[0004] The above contents are only used to assist in understanding the technical solution of the invention and do not constitute an admission that the above contents are prior art. Summary of the invention

[0054] In the embodiment of the present invention, please refer to Figure 1 and Figure 2As shown, the electric toothbrush includes multiple actuators, a first communication module, a control chip, a drive shutdown circuit and at least one power element; wherein the control chip is communicatively connected to the first communication module, and controls the connection of at least some of the actuators and at least one power element through the drive shutdown circuit; the control chip obtains a control signal through the first communication module, and the control chip controls at least some of the actuators and the power elements to be turned off / on at the same time through the drive shutdown circuit according to the control signal.

[0055] In this embodiment, the electric toothbrush at least includes a plurality of actuators, a first communication module, a control chip, a drive shutdown circuit and a power element (in this article, the power element is mainly a motor). The plurality of actuators are electronic components that support the normal operation and use of the electric toothbrush; the first communication module is interconnected with the mobile terminal that controls the electric toothbrush and completes communication, and the first communication module includes but is not limited to Bluetooth; the control chip controls the plurality of actuators and power elements of the electric toothbrush according to the user's instructions; the drive shutdown circuit is the control chip that controls the power of some actuators of the electric toothbrush to turn off / on according to the user's instructions. Specifically, the control chip is connected to the first communication module, and at least some of the actuators and power elements are connected to the drive shutdown circuit. It should be noted that some of the actuators connected to the control chip through the drive shutdown circuit are standby non-operating elements, that is, when the electric toothbrush is in standby state, some of the actuators and power elements connected to the control chip through the drive shutdown circuit are not running, and the standby elements of the electric toothbrush are not affected. Its working principle is that the control chip obtains the control signal sent by the user through the first communication module, and the control chip drives the shutdown circuit to control at least some of the actuators and power elements that do not affect the standby state of the electric toothbrush to be turned off / on at the same time according to the control signal. That is, the electric toothbrush is continuously in the standby state, and the user sends a control signal to turn off the electric toothbrush through the mobile terminal, and after the control chip receives the control signal, it controls all the actuators and power elements that do not affect the standby state of the electric toothbrush to be turned off. The actuators described here are indicator lights, some detection sensors, etc. When the user needs to use the electric toothbrush, the user sends a control signal to turn on the electric toothbrush through the mobile terminal, and after the control chip receives the control signal, it controls all the actuators and power elements that have been turned off to allow the user to use the electric toothbrush normally.

[0056] In the present embodiment, at least part of the actuators and at least one power element of the electric toothbrush that is continuously in the on state are controlled to be turned off / on at the same time by driving the shutdown circuit, that is, when the electric toothbrush is not needed, at least part of the actuators and at least one power element are turned off at the same time, and when the electric toothbrush is needed, the closed actuators and at least one power element are turned on at the same time. Compared with the electric toothbrush in the prior art, the present invention reduces the standby power consumption of the electric toothbrush and improves the endurance of the electric toothbrush by turning off the power element and part of the actuators at the same time in the standby state; compared with the prior art that requires manual power-on of the electric toothbrush, the present invention reduces the user's power-on process of the electric toothbrush by keeping the electric toothbrush in the standby state, thereby simplifying the tediousness of the user's use of the electric toothbrush.

[0057] Furthermore, the drive shutdown circuit includes a first resistor, a second resistor, a third resistor, a first static point, and a second static point; wherein the input end of the first resistor is connected to the contact of the control chip; the first resistor, the first static point, the third resistor, and the second static point are connected in series end to end, and the output end of the second static point is respectively connected to part of the actuator and the power element; the second resistor is connected in parallel to the output end of the first resistor and the input end of the first static point, and the output end of the second resistor is grounded; the output end of the first static point is connected in parallel to the input end of the second static point; when the control chip controls at least part of the actuator and the power element to be turned off at the same time according to the control signal, the control signal passes through the first resistor, the second resistor, the third resistor, the first static point, and the second static point in sequence.

[0058] This embodiment describes the drive shutdown circuit in detail, and the drive shutdown circuit includes a first resistor, a second resistor, a third resistor, a first static point, and a second static point; the input end of the first resistor is connected to the contact of the control chip, and the output end of the first resistor, the first static point, the third resistor, and the second static point are connected end to end in sequence, and the output end of the second static point is respectively connected to some actuators and power elements, and the connected some actuators are standby non-operating elements. The second resistor is connected in parallel to the output end of a resistor and the output end of the first static point, and the output end of the second resistor is grounded; the output end of the first static point is connected in parallel to the input end of the second static point. Its working principle and flow are as follows: when the control chip controls the actuator of the standby non-operating element according to the control signal, the first static point and the second static point will automatically change the working mode according to whether there is a control signal passing through. When there is a control signal, the control signal passes through the first resistor, the second resistor, the third resistor, the first static point, and the second static point in sequence to control the actuator and the power element of the standby non-operating element to turn off / on. When there is no control signal, the first static point and the second static point automatically change the working mode to enter a low-power mode, so that the entire drive shutdown circuit enters a low-power mode. In this embodiment, when the electric toothbrush is on standby, the operation of at least one drive shutdown circuit turns off other standby non-operating elements and the power element. The standby non-operating elements described here are indicator lights, some detection sensors, etc. Compared with the electric toothbrush when all other actuators except the power element that has not entered the working state are operating normally, the power consumption of the electric toothbrush in the standby state is reduced, and the endurance of the electric toothbrush is improved.

[0059] Further, the resistance value of the first resistor is 21Ω~23Ω, and the resistance value of the first resistor is specifically 22Ω1%; the resistance value of the second resistor is 900Ω~1100Ω, and the resistance value of the second resistor is specifically 1KΩ1%; the resistance value of the third resistor is 1800Ω~2200Ω, and the resistance value of the third resistor is specifically 2KΩ1%.

[0060] Furthermore, the plurality of execution elements include a plurality of standby operation elements and a plurality of standby non-operation elements, and the control chip simultaneously turns off / on the plurality of standby non-operation elements by driving the shutdown circuit according to the control signal.

[0061] In this embodiment, multiple actuators are described in detail. The multiple actuators include standby operating elements and multiple standby non-operating elements. The multiple standby operating elements are necessary operating elements for putting the electric toothbrush in standby mode. The multiple standby non-operating elements are elements that are not necessary to operate when the electric toothbrush is in standby mode. The standby operating elements at least include the first communication module, control chip and drive shutdown circuit provided in the above embodiments.

[0062] Furthermore, the electric toothbrush is provided with at least one control button, which is connected to a control chip. When the control button is pressed, a button signal is generated. The control chip drives a closing circuit according to the button signal to control at least some actuators and power elements to be closed / opened at the same time.

[0063] In this embodiment, at least one control button is provided on the electric toothbrush, and the control button is connected to the control chip. When the user does not use the mobile terminal to send a control signal, the control button can generate a pressing signal according to pressing the control button, and then the control chip controls at least part of the actuators and power elements to be turned off / on at the same time by driving the shutdown circuit according to the pressing signal. In this embodiment, the control button is used to control part of the actuators and power elements to be turned off / on at the same time when the electric toothbrush is in standby state, thereby reducing the standby power consumption of the electric toothbrush when it is turned on and improving the battery life of the electric toothbrush.

[0064] Furthermore, the electric toothbrush also includes a communication detection module, which is connected to the control chip and the first communication module, and the communication detection module is used to detect the communication status of the first communication module; when the communication detection module detects that the communication status of the first communication module is connected, the communication detection module generates a connection signal and sends it to the control chip, and the control chip controls at least part of the actuator and the power element to be turned off / on at the same time by driving the shutdown circuit according to the control signal; when the communication detection module detects that the communication status of the first communication module is disconnected, the communication detection module generates a disconnection signal and sends it to the control chip, and the control chip controls at least part of the actuator and the power element to be turned off at the same time by driving the shutdown circuit according to the disconnection signal.

[0065] In this embodiment, the electric toothbrush also includes a communication detection module for detecting the communication state of the first communication module to identify whether the first communication module is in a connected state or a disconnected state, and the control chip actively controls the simultaneous closing / opening of some actuators and power elements of the electric toothbrush according to the communication state of the first communication module. Specifically, the communication detection module connects the control chip and the first communication module to realize that the communication detection module detects the communication state of the first communication module and sends the detection result to the control chip. When the communication state of the first communication module detected by the communication detection module is connected, the communication detection module generates a connection signal and sends it to the control chip. The control chip will control at least some actuators and power elements to be closed / opened at the same time according to the control signal sent by the mobile terminal and by driving the closing circuit. When the communication detection module detects that the communication state of the first communication module is disconnected, the communication detection module generates a disconnection signal and sends the disconnection signal to the control chip. The control chip will actively control at least some actuators and power elements to be closed at the same time by driving the closing circuit according to the disconnection signal. Compared with the prior art in which only the power element is closed when the electric toothbrush is on standby, the standby power consumption of the electric toothbrush is reduced and the battery life of the electric toothbrush is improved. That is, in this embodiment, when the user has finished using the electric toothbrush and has not controlled the electric toothbrush to enter standby mode through the mobile terminal, but the user actively closes the communication connection with the electric toothbrush through the mobile terminal, it means that the user does not need to use the electric toothbrush anymore, so the control chip will control at least some of the actuators and power elements of the electric toothbrush to shut down at the same time.

[0066] In this embodiment, by detecting the first communication module, it is determined that the user no longer needs to use the electric toothbrush, and the control chip actively turns off some actuators and power elements at the same time, thereby reducing the situation where the user forgets to turn off some actuators and power elements and puts the electric toothbrush into standby mode. The control chip controls the electric toothbrush to actively enter standby mode, thereby reducing the power consumption of the electric toothbrush when it is not in use and not in standby mode.

[0067] Furthermore, the electric toothbrush also includes a timing module, which is used to time and obtain a duration value;

[0068] A duration threshold is preset in the control chip. When the control chip receives a connection signal, the control chip generates a timing signal, and controls the timing module according to the timing signal to time each control signal and obtain the duration value of each control signal in real time. The control chip continuously compares the duration value with the duration threshold. When the duration value is greater than or equal to the duration threshold and the control chip does not receive the next control signal, the control chip controls at least part of the actuator and the power element to be closed at the same time by driving the closing circuit.

[0069] In this embodiment, the electric toothbrush also includes a timing module, which is used to time and obtain the duration value of each control signal. A duration threshold is preset in the control chip, and the duration threshold is the judgment standard. When the control chip receives the connection signal, the control chip generates a timing signal and controls the timing module to obtain the duration value of each control signal in real time according to the timing signal, and the control chip continuously compares the obtained duration value with the duration threshold. When the duration value is greater than or equal to the duration threshold, the control chip will actively control at least part of the actuator and the power element to be closed at the same time by driving the closing circuit. That is, when the user is using the electric toothbrush, he is suddenly interrupted by other temporary emergencies, and the user does not send a control signal through the mobile terminal to make the electric toothbrush enter standby mode. At this time, the electric toothbrush will continue to work in the state when the user is using it. When the time when the user leaves exceeds the duration threshold, the control chip will control the electric toothbrush to actively standby, that is, close part of the actuator and the power element, so as to reduce the time of invalid operation of the electric toothbrush and improve the battery life of the electric toothbrush.

[0070] Furthermore, the electric toothbrush also includes a brush handle and a brush head; wherein the brush handle and the brush head are detachably connected, and a plurality of actuators, a first communication module, a control chip, a drive shutdown circuit and at least one power element are respectively arranged on the brush handle.

[0071] In this embodiment, the electric toothbrush includes a brush handle for a user to hold when using the electric toothbrush and a brush head for cleaning teeth. The brush handle and the brush head are detachably connected, and multiple actuators, a first communication module, a control chip, a drive shutdown circuit board, and a power element are respectively arranged on the brush handle. It should be noted that any or all of the multiple actuators, the first communication module, the control chip, the drive shutdown circuit board, and the power element can be arranged on the brush head.

[0072] Furthermore, the electric toothbrush also includes an acceleration sensor, which is connected to the control chip, and the acceleration sensor is used to detect and obtain the acceleration value of the electric toothbrush; an acceleration threshold is preset in the control chip, and when the control chip receives a control signal, the control chip obtains the acceleration value based on the acceleration sensor, and compares the acceleration value with the acceleration threshold. When the acceleration value is greater than or equal to the acceleration threshold, the control chip controls at least part of the actuator and the power element to be turned off / on at the same time by driving the shutdown circuit according to the control signal; when the acceleration value is less than the acceleration threshold, the control chip controls at least part of the actuator and the power element to be turned off at the same time by driving the shutdown circuit.

[0073] In this embodiment, the electric toothbrush also includes an acceleration sensor, which is used to detect and obtain the acceleration value of the electric toothbrush, and the acceleration sensor is connected to the control chip. An acceleration sensing threshold is preset in the control chip. When the control chip receives a control signal sent by the mobile terminal, the control chip will obtain the acceleration value by controlling the acceleration sensor, and compare the acceleration value with the acceleration threshold. When the acceleration value is greater than or equal to the acceleration threshold, the control chip will control the simultaneous closing / opening of some actuators and power elements according to the control signal sent by the user through the mobile terminal and by driving the closing circuit. When the acceleration value is less than the acceleration threshold, the control chip will actively control the simultaneous closing of some actuators and power elements by driving the closing circuit. That is, when the user picks up the electric toothbrush, the acceleration sensor detects that the user picks up the electric toothbrush, and the simultaneous closing / opening of some actuators and power elements of the electric toothbrush will be controlled according to the control signal sent by the user through the mobile terminal. When the user puts down the electric toothbrush, the acceleration sensor can also be used to detect that the user has put down the electric toothbrush, thereby determining that the user has finished brushing teeth with the electric toothbrush or has paused using the electric toothbrush. At this time, the control chip will actively shut down the operation of some actuators and power elements, thereby reducing the process of the user using the mobile terminal to turn off the electric toothbrush, making it more convenient to use the electric toothbrush. If the user forgets to turn off the electric toothbrush through the mobile terminal, the electric toothbrush will also actively shut down some actuators and power elements of the electric toothbrush when the user puts down the electric toothbrush, thereby reducing the operating time of some actuators and power elements of the electric toothbrush that are not necessary, thereby improving the battery life of the electric toothbrush.

[0074] Furthermore, when the control chip does not receive the control signal, the control chip turns off the acceleration sensor by driving the shutdown circuit, and the acceleration sensor stops detecting the acceleration value.

[0075] In this embodiment, when the control chip does not receive the control signal sent by the user through the mobile terminal, the control chip will turn off the acceleration sensor by driving the shutdown circuit, so that the acceleration sensor stops detecting the acceleration value of the electric toothbrush. That is, in this embodiment, when the electric toothbrush is turned on and in standby mode, the acceleration sensor will also be turned off by the control chip to reduce the power consumption of the electric toothbrush in standby mode and improve the battery life of the electric toothbrush.

[0076] Furthermore, the acceleration value includes acceleration values ​​in three axes, x, y, and z; when the control chip controls at least some of the actuators and power elements to be turned on at the same time by driving the closing circuit according to the control signal, the control chip generates an information acquisition signal, and controls the acceleration sensor to continuously obtain acceleration x information, acceleration y information, and acceleration z information according to the information acquisition signal. The control chip calculates the motion trajectory information of the electric toothbrush according to the acceleration x information, acceleration y information, and acceleration z information, and draws a motion trajectory image according to the motion trajectory information and sends it through the first communication module.

[0077] In this example, the acceleration values ​​detected by the acceleration include acceleration values ​​in three axes, x, y, and z. When the user sends a control signal through the mobile terminal, and the control chip drives the closing circuit control part of the actuator and the power element to turn on at the same time according to the control signal, the control chip generates an information acquisition signal, that is, when the user uses the electric toothbrush, the control chip generates an information acquisition signal. At this time, the control chip controls the acceleration sensor to continuously obtain acceleration x information, acceleration y information, and acceleration z information according to the generated information acquisition signal, and the control chip calculates the motion trajectory information of the electric toothbrush according to the acquired acceleration x information, acceleration y information, and acceleration z information. The control chip draws the running trajectory image according to the running trajectory information and sends it to the mobile terminal through the first communication module to display the brushing trajectory of the electric toothbrush. That is, in this embodiment, the running trajectory of the electric toothbrush when the user uses the electric toothbrush is identified by the acceleration sensor and displayed on the mobile terminal, so that the brushed part of the teeth and the unbrushed part of the teeth can be intuitively observed, thereby improving the efficiency and fun of the user using the electric toothbrush.

[0078] Furthermore, the electric toothbrush also includes a temperature sensor, which is arranged on the brush head and connected to the control chip. The temperature sensor is used to detect the temperature value of the environment in which the electric toothbrush is located; a temperature threshold is preset in the control chip. When the control chip generates an information acquisition signal, the control chip controls the temperature sensor to detect the temperature value and compares the temperature value with the temperature threshold. When the temperature value is greater than or equal to the temperature threshold, the control chip obtains acceleration x information, acceleration y information, and acceleration z information with the current position of the acceleration sensor as the origin.

[0079] In this embodiment, a temperature sensor is also provided on the electric toothbrush. The temperature sensor is used to detect the temperature value of the environment in which the electric toothbrush is located, and the temperature sensor is arranged on the brush head. When the user uses the electric toothbrush, the brush head will enter the oral cavity. Obviously, the temperature inside the oral cavity will be higher than the ambient temperature outside the oral cavity. Therefore, it is judged whether the user is brushing his teeth with the electric toothbrush by the change in temperature. Specifically, the temperature sensor is connected to the control chip, and a temperature threshold is preset in the control chip. When the control chip generates an information acquisition signal according to the aforementioned embodiment, the control chip will control the temperature sensor to detect the temperature value and compare the temperature value with the temperature threshold. When the temperature value is greater than or equal to the temperature threshold, that is, when the user uses the electric toothbrush and the brush head of the electric toothbrush is in the user's mouth, the control chip will use the current position of the acceleration sensor as the origin to obtain acceleration x information, acceleration y information, and acceleration z information for the control chip to calculate the motion trajectory information of the electric toothbrush. This embodiment describes that only when the user uses the brush head of the electric toothbrush to enter the oral cavity will the acceleration x information, acceleration y information, and acceleration z information be obtained according to the acceleration sensor, thereby reducing the invalid acceleration x information, acceleration y information, and acceleration z information detected when the brush head of the electric toothbrush has not entered the user's mouth, thereby improving the accuracy of the motion trajectory image and reducing the workload of the acceleration sensor at the same time, thereby reducing the power consumption of the acceleration sensor and improving the battery life of the electric toothbrush. It should also be noted that when the acceleration sensor obtains acceleration x information, acceleration y information, and acceleration z information with the current acceleration sensor as the origin, the control chip will control the temperature sensor to be turned off to reduce power consumption when the temperature sensor is running.

[0080] Furthermore, when the control chip does not generate an information collection signal, the control chip turns off the temperature sensor by driving the shutdown circuit, and the temperature sensor stops detecting the temperature value of the environment in which the electric toothbrush is located.

[0081] In this embodiment, when some of the actuators and power elements of the electric toothbrush are turned on at the same time, and when the control chip does not generate an information collection signal, the control chip will actively turn off the temperature sensor by driving the shutdown circuit, and the temperature sensor will stop detecting the temperature value of the environment in which the electric toothbrush is located. That is, in this embodiment, when the electric toothbrush is turned on and in standby mode, the temperature sensor will also be turned off by the control chip to reduce the power consumption of the electric toothbrush in standby mode and improve the battery life of the electric toothbrush.

[0082] Furthermore, the electric toothbrush also includes a photosensor, which is arranged on the brush head and connected to the control chip. The photosensor is used to detect the ambient light value of the environment in which the electric toothbrush is located; an ambient light threshold is preset in the control chip. When the control chip generates an acquisition signal, the control chip controls the photosensor to detect the ambient light threshold and compares the ambient light value with the ambient light threshold. When the ambient light value is less than the ambient light threshold, the control chip obtains acceleration x information, acceleration y information, and acceleration z information with the current position of the acceleration sensor as the origin.

[0083] In this embodiment, a photosensor is provided on the electric toothbrush. The photosensor is arranged on the brush head of the electric toothbrush. The photosensor is used to detect the ambient light value of the environment in which the electric toothbrush is located. To be more precise, it should be to detect the ambient light value of the environment in which the brush head of the electric toothbrush is located. When the user uses the electric toothbrush, the electric toothbrush will enter the oral cavity. Obviously, the ambient light value inside the oral cavity will be smaller than the ambient light value outside the oral cavity. Therefore, it is judged whether the user is brushing his teeth with the electric toothbrush by the change of the ambient light value. Specifically, the photosensor is connected to the control chip, and an ambient light threshold is preset in the control chip. When the control chip generates an information collection signal according to the aforementioned embodiment, the control chip will detect the ambient light value through the photosensor, and compare the ambient light value with the ambient light threshold. When the ambient light value is greater than or equal to the ambient light threshold, that is, the user uses an electric toothbrush and the brush head of the electric toothbrush is in the user's mouth, the control chip will use the current position of the acceleration sensor as the origin to obtain acceleration x information, acceleration y information, and acceleration z information for the control chip to calculate the motion trajectory information of the electric toothbrush. This embodiment describes that only when the user uses the brush head of the electric toothbrush to enter the oral cavity will the acceleration x information, acceleration y information, and acceleration z information be obtained according to the acceleration sensor, thereby reducing the invalid acceleration x information, acceleration y information, and acceleration z information detected when the brush head of the electric toothbrush has not entered the user's mouth, thereby improving the accuracy of the motion trajectory image, and at the same time reducing the workload of the acceleration sensor, thereby reducing the power consumption of the acceleration sensor and improving the battery life of the electric toothbrush. It should also be noted that when the acceleration sensor obtains acceleration x information, acceleration y information, and acceleration z information with the current acceleration sensor as the origin, the control chip will control the photosensitive sensor to turn off to reduce the power consumption caused by the operation of the photosensitive sensor.

[0084] Furthermore, when some actuator elements and power elements of the electric toothbrush are turned on at the same time, and when the control chip does not generate an information collection signal, the control chip will actively turn off the photosensitive sensor by driving the shutdown circuit, and the photosensitive sensor will stop detecting the ambient light value of the environment in which the electric toothbrush is located. That is, in this embodiment, when the electric toothbrush is turned on and in standby mode, the photosensitive sensor will also be turned off by the control chip to reduce the power consumption of the electric toothbrush in standby mode and improve the battery life of the electric toothbrush.
