Description

Technical Field

[0001] This application relates to the field of cleaning appliance technology, and in particular to a control method, control device and electric toothbrush for an electric toothbrush. Background Technology

[0002] An electric toothbrush is a cleaning device that uses a high-speed vibrating motor to rotate or vibrate the brush head to clean teeth. Most electric toothbrushes are controlled by a mechanical switch to start or stop, while a few use capacitive touch-sensitive switches.

[0003] The electrical conductivity of saliva (mixed with toothpaste and water as needed) can be used in the circuitry that activates an electric toothbrush. When the brush head is in the mouth, one or more of the conditions described in the circuitry exist to provide the basis for the automatic operation of the electric toothbrush, and this condition or combination of conditions is detected. However, when brushing the outer surfaces of the incisors or the occlusal surfaces of the left and right incisors, saliva or foam may be dislodged by the brush head vibrations, causing the electric toothbrush to stop working and reducing the user experience. Summary of the Invention

[0004] In view of this, the purpose of this application is to overcome the shortcomings of the prior art. This application provides a control method for an electric toothbrush to solve the technical problem in the prior art that when an electric toothbrush is brushing the outer surface of the incisor area or the occlusal surface of the left and right incisors, saliva or foam may be dislodged by the vibration of the brush head, causing the electric toothbrush to stop working.

[0005] The first aspect of this application provides a method for controlling an electric toothbrush, comprising:

[0006] Get the current voltage value of the electric toothbrush;

[0007] If the current voltage value is not less than the preset voltage value, the electric toothbrush is controlled to start the cleaning operation. During the cleaning operation of the electric toothbrush, the brushing area of ​​the electric toothbrush head in the human oral cavity is detected.

[0008] If the brushing area is located in the preset area, the electric toothbrush is controlled to continue cleaning.

[0009] If the brushing area is not located in the preset area and the current voltage value is less than the preset voltage value, the electric toothbrush will be controlled to stop cleaning.

[0010] In some embodiments of this application, during the cleaning process of the electric toothbrush, the control method further includes:

[0011] The current pressure value applied to the brush head of the electric toothbrush is obtained; if the current pressure value is less than a preset pressure value, the electric toothbrush is controlled to turn off or stop cleaning.

[0012] In some embodiments of this application, during the cleaning process of the electric toothbrush, the control method further includes:

[0013] Obtain the current angle value of the electric toothbrush;

[0014] If the current angle value is within a preset angle threshold and the current voltage value is less than the preset voltage value, then the electric toothbrush is controlled to turn off or stop cleaning.

[0015] In some embodiments of this application, before obtaining the current voltage value of the electric toothbrush, the control method further includes:

[0016] Obtain the current angle value of the electric toothbrush;

[0017] If the current angle value is not within the preset angle threshold, the electric toothbrush is activated, but it does not perform cleaning work.

[0018] In some embodiments of this application, the preset angle threshold ranges from 75 degrees to 105 degrees.

[0019] A second aspect of this application provides a control device for an electric toothbrush, comprising:

[0020] The first acquisition module is used to acquire the current voltage value of the electric toothbrush;

[0021] The first control module is used to control the electric toothbrush to start cleaning if the current voltage value is not less than the preset voltage value.

[0022] The detection module is used to detect the brushing area of ​​the electric toothbrush head in the human oral cavity during the cleaning process of the electric toothbrush.

[0023] The second control module is used to control the electric toothbrush to continue cleaning if the brushing area is located in a preset area; and to control the electric toothbrush to stop cleaning if the brushing area is not located in the preset area and the current voltage value is less than the preset voltage value.

[0024] In some embodiments of this application, the control device for the electric toothbrush further includes:

[0025] The second acquisition module is used to acquire the current pressure value applied to the brush head;

[0026] The third control module is used to control the electric toothbrush to turn off or stop cleaning if the current pressure value is less than the preset pressure value.

[0027] In some embodiments of this application, the control device for the electric toothbrush further includes:

[0028] The third acquisition module is used to acquire the current angle value of the electric toothbrush;

[0029] The fourth control module is used to control the electric toothbrush to turn off or stop cleaning if the current angle value is within a preset angle threshold; and to control the electric toothbrush to start if the current angle value is not within the preset angle threshold.

[0030] A third aspect of this application provides an electric toothbrush, including a memory, a processor, and a computer program stored in the memory and executable on the processor, wherein the processor executes the computer program to implement the control method of the electric toothbrush described in any of the above embodiments.

[0031] A fourth aspect of this application provides a computer-readable storage medium storing a computer program that, when executed by a processor, implements the electric toothbrush control method as described in any of the above embodiments.

[0032] Compared to existing technologies, the beneficial effects of this application are as follows: This application proposes a control method for an electric toothbrush. It acquires the current voltage value of the electric toothbrush. If the current voltage value is not less than a preset voltage value, it controls the movement of the toothbrush head to enter brushing mode. During the brush head movement, it detects the brushing area of ​​the brush head within the oral cavity. If the brushing area is within a preset area, it controls the brush head to continue moving. This avoids the situation where the brush head stops moving in the brushing area due to the current voltage value being less than the preset voltage value, thus preventing brushing interruption. This solves the problem of accidental interruption of brushing in specific brushing areas during the brushing process, improving the user experience. Attached Figure Description

Detailed Implementation

[0049] The embodiments of this application are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this application, and should not be construed as limiting this application.

[0050] In the description of this application, it should be understood that the terms "center", "longitudinal", "lateral", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", "counterclockwise", "axial", "radial", "circumferential", etc., indicating the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this application.

[0051] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this application, "multiple" means two or more, unless otherwise explicitly specified.

[0052] In this application, unless otherwise expressly specified and limited, the terms "installation," "connection," "linking," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this application according to the specific circumstances.

[0053] In this application, unless otherwise expressly specified and limited, "above" or "below" the second feature can mean that the first feature is in direct contact with the second feature, or that the first feature is in indirect contact with the second feature through an intermediate medium. Furthermore, "above," "on top of," and "over" the second feature can mean that the first feature is directly above or diagonally above the second feature, or simply that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature can mean that the first feature is directly below or diagonally below the second feature, or simply that the first feature is at a lower horizontal level than the second feature.

[0054] Example 1

[0055] First, it should be noted that tooth zoning refers to the pre-division of tooth regions based on the distribution of all teeth in the human oral cavity. The human oral cavity can be divided into several tooth zoning regions. Taking an adult with 32 teeth as an example, the 32 teeth can be divided into 6 tooth zoning regions. The maxillary left region, maxillary right region, mandibular left region, and mandibular right region include the lateral surface, medial surface, and occlusal surface, respectively. The maxillary middle region and mandibular middle region both include the lateral surface and medial surface. Thus, a total of 16 tooth surfaces can be determined for the 6 tooth zoning regions.

[0056] An electric toothbrush incorporates a three-axis accelerometer to detect the toothbrush's acceleration along the X, Y, and Z axes during brushing. It may also include a three-axis gyroscope to detect the toothbrush's angular velocity along these axes. After acquiring the three-axis acceleration from the accelerometer and the three-axis angular velocity from the gyroscope, Kalman filtering is applied to both. The filtered acceleration and angular velocity are then fused using Madgwick attitude fusion processing to obtain the toothbrush's three attitude data points at the current brushing position: roll angle, pitch angle, and yaw angle.

[0057] The rolling angle (Roll) and yaw angle are used to determine which of the six tooth zones the current brushing position is located in, such as whether it is in the maxillary left zone, mandibular middle zone, or maxillary right zone. After determining the brushing zone, the rolling angle (Roll) is used to further determine which brushing surface within that zone. For example, if the current brushing position is determined to be in the maxillary left zone, it is further determined whether it is the lateral surface, medial surface, or occlusal surface of the maxillary left zone. The pitch angle can also be used to assist in determining the tooth zone and brushing surface of the current brushing position.

[0058] During brushing, when the electric toothbrush is brushing on the outer surfaces of the left and right maxillary regions or the occlusal surfaces of the left and right mandibular regions, saliva or foam may be vibrated and fall off, causing the electric toothbrush to stop working.

[0059] like Figure 1 As shown, in order to solve the problem of accidental interruption of electric toothbrushes in the mouth, embodiments of this application provide a control method for an electric toothbrush, including the following steps:

[0060] S1: Obtain the current voltage value of electric toothbrush 100.

[0061] See also Figure 9 and Figure 10 Specifically, the electric toothbrush 100 is equipped with a voltage detection device, and the brush head 50 is equipped with a metal conductor 70. At the same time, the brush head 50 has at least one liquid inlet hole 51, so that when the brush head 50 is placed in the mouth, liquid (saliva or water) can enter through the liquid inlet hole 51. The saliva or water in the liquid inlet hole 51 comes into contact with the skin of the human mouth. At the same time, the saliva or water entering the liquid inlet hole 51 comes into contact with the metal conductor 70, thus making the metal conductor 70 conductive with the human body. At this time, the voltage detection device can detect the current voltage value.

[0062] Understandably, in acquiring the current voltage value of the electric toothbrush 100, the current voltage value can be acquired in real time. Alternatively, it can be acquired periodically, such as once every 1-8 seconds or once every 16-24 seconds. Of course, the interval can be adjusted according to design requirements.

[0063] It should be noted that the voltage detection device is activated after the electric toothbrush 100 is turned on. The voltage detection device can be an operational amplifier circuit or a transistor. The aforementioned operational amplifier circuit or transistor for detecting voltage is configured on the printed circuit board assembly (PCBA). At the same time, a control chip or control circuit electrically connected to the transistor or operational amplifier circuit is configured to compare the current voltage value obtained by the operational amplifier circuit or transistor with a preset voltage value.

[0064] S2: If the current voltage value is not less than the preset voltage value, the electric toothbrush 100 is controlled to start the cleaning operation. During the cleaning operation of the electric toothbrush 100, the brush head 50 of the electric toothbrush 100 is detected in the brushing area inside the human mouth.

[0065] Specifically, the brush head 50 can be driven to move by the motor 60 inside the handle of the electric toothbrush 100 to perform cleaning work.

[0066] It should be noted that the preset voltage value is determined based on pre-tested experimental data. For example, in a liquid-free environment, the detected current voltage value is within 50mV (millivolts). When the brush head 50 is immersed in water, the detected current voltage is 17V (volts). When human skin comes into contact with water, and the brush head 50 is in contact with the water at a distance of 20-30mm (millimeters), the detected current voltage value is approximately 104V. Specifically, in step S2, after the brush head 50 moves, it enters the brushing mode in the oral cavity. During the movement of the brush head, the electric toothbrush 100 detects the brushing area of ​​the brush head 50 in the human oral cavity. The current brushing position is determined based on the rolling angle (Roll) and the yaw angle (Yaw) within the six tooth zones.

[0067] S3: If the brushing area is located in the preset area, control the electric toothbrush 100 to continue cleaning.

[0068] Specifically, the preset area can be determined based on experimental data as the lateral surface of the left and right maxillary regions, and / or the occlusal surface of the left and right mandibular regions.

[0069] The system detects which area the brushing head 50 is located on. If it determines that the current brushing area is the lateral surface of the maxillary left and right regions, and / or the occlusal surface of the mandibular left and right regions, it controls the brush head 50 to continue moving, which means controlling the motor 60 inside the electric toothbrush 100 to continue operating. This avoids the brush head 50 stopping when the current voltage value in the brushing area is lower than the preset voltage value, thus preventing brushing interruptions. It solves the problem of accidental interruptions in specific brushing areas during brushing, improving the user experience.

[0070] S4: If the brushing area is not located in the preset area and the current voltage value is less than the preset voltage value, then control the electric toothbrush 100 to stop cleaning.

[0071] Specifically, when it is determined that the current brushing position is not on the outer surface of the left and right maxillary regions, and / or the occlusal surface of the left and right mandibular regions, and saliva or foam is easily shaken off, thus causing the detected current voltage value to be less than the preset voltage value, the motor 60 of the electric toothbrush 100 is stopped, that is, the brush head 50 is stopped.

[0072] It is understandable that if the brushing area is not located in the preset area, and the current voltage value is not less than the preset voltage value, the toothbrush will continue to move. That is, when the current voltage value is not less than the preset voltage value, the motor 60 of the electric toothbrush 100 will not be stopped. Specifically, when the current brushing position is on the inner surface of the left and right maxillary regions, and / or the inner and outer surfaces of the left and right mandibular regions, saliva or foam is less likely to be vibrated and fall off inside the mouth, thus preventing the motor 60 from being interrupted. This is because when the brushing position is on the inner surface of the left and right maxillary regions, and / or the inner and outer surfaces of the left and right mandibular regions, there will be a lot of saliva in the mouth, making it less likely to be vibrated and fall off.

[0073] like Figure 2 As shown, in addition, as an optional embodiment, step S2 may also include step S21: the acquisition of the current voltage value of the electric toothbrush may be paused within a first preset time value after the brush head starts cleaning, and the brush head may be controlled to continue cleaning according to a second preset time value.

[0074] Specifically, in step S2, after the brush head 50 moves, it enters the brushing mode in the oral cavity. At this time, the acquisition of the current voltage value is paused for a first preset time value, while the brush head is controlled to continue moving for a second preset time value.

[0075] It should be noted that the first preset time value can be 7 seconds, and the second preset time value can be 7 seconds, 8 seconds, or 9 seconds.

[0076] S22: Reacquire the current voltage value of the electric toothbrush after the first preset time value.

[0077] Specifically, after pausing for the first preset time value, the current voltage value is re-detected until it is not less than the preset voltage value, preventing the brush head 50 from stopping. If the brush head 50 has already moved for the second preset time value, it stops moving. If the current voltage value is not less than the preset voltage value, the brush head 50 is controlled to continue moving, allowing the user to select other brushing areas for the second preset time value. The brushing areas include the lateral and medial surfaces of the left and right maxillary regions, and / or the occlusal and medial surfaces of the left and right mandibular regions.

[0078] Understandably, users can select a washing area based on the duration of each brush head 50 movement. Before the brush head 50 stops moving, it can be reactivated to obtain the current voltage value. If the current voltage value is not less than the preset voltage value, the brush head 50 will continue moving for a second preset time value to select another washing area. Alternatively, if the brush head 50's movement time has reached the second preset time value while obtaining the current voltage value, the brush head 50 will stop moving. In this case, if the current voltage value is not less than the preset voltage value, the brush head 50 will restart moving for the second preset time value to wash the currently selected area.

[0079] It should be noted that the second preset time value was selected based on the experimental design to meet the brushing time of each brushing area.

[0080] S23: During the user's brushing process, steps S21 and S22 can be repeated to achieve reciprocating brushing. During this process, the user can select different brushing areas for each repetition. These brushing areas can be the designated brushing areas, or the preset or non-preset areas from steps S3 or S4. It is understood that if the user selects the lateral surface of the maxillary left and right sides, and / or the occlusal surface of the mandibular left and right sides, the continuous movement of the brush head 50 will not stop the motor 60 of the electric toothbrush 100, even if the current voltage value is lower than the preset voltage value. In other words, when the current brushing position is on the inner surface of the left and right maxillary regions, and / or the inner and outer surfaces of the left and right mandibular regions, saliva or foam is less likely to be vibrated and fall off inside the mouth, thus preventing the motor from being interrupted. This is because when the brushing position is on the inner surface of the left and right maxillary regions, and / or the inner and outer surfaces of the left and right mandibular regions, there will be a lot of saliva in the mouth, making it less likely to be vibrated and fall off.

[0081] In addition, during the period when the acquisition of the current voltage value is paused (the first preset time value), compared to acquiring the current voltage value in real time, power consumption is saved, the power consumption of the electric toothbrush is reduced, and the battery life of the electric toothbrush is improved.

[0082] The first preset time value is not greater than the second preset time value. This allows the brush head to restart and acquire the current voltage value before it stops moving. During the acquisition of the current voltage value, the brush head's movement time has reached the second preset time value, at which point the brush head stops moving. If the current voltage value is not less than the preset voltage value, the brush head is controlled to continue moving for the second preset time value to clean the currently selected area.

[0083] Optionally, the second preset time value can be selected from 7s to 12s. Of course, other times can also be selected according to design needs.

[0084] Example 2

[0085] like Figure 3 As shown, after the problem of accidental interruption of the electric toothbrush 100 in the mouth was solved in the above embodiment one, the goal of allowing the user to stop the electric toothbrush 100 at any time has not yet been achieved. To address the user's desire to stop the electric toothbrush 100 at any time, this application also provides the following embodiment: In step S2, after the brush head 50 moves, the control method further includes the following step:

[0086] S201: Obtain the current pressure value applied to the brush head 50.

[0087] Specifically, a pressure sensor is provided in the handle of the electric toothbrush 100, and the pressure detected by the pressure sensor is the pressure value experienced by the brush head 50. This pressure sensor can be used to detect the pressure of each brushing surface when the user performs brushing action using the electric toothbrush 100.

[0088] Understandably, the current pressure value received by the brush head can be obtained in real time or periodically, and the periodic interval can be set according to actual needs.

[0089] S202: If the current pressure value is less than the preset pressure value and the current voltage value is less than the preset voltage value, then the electric toothbrush 100 is controlled to turn off or stop cleaning, i.e., the electric toothbrush 100 stops working. That is, when it is determined that the current pressure value is not less than the preset pressure value, the electric toothbrush 100 is controlled to stop working. This design allows the user to stop the electric toothbrush 100 at any time.

[0090] It is understood that if the current pressure value is not less than the preset pressure value, the electric toothbrush 100 will continue to perform cleaning work.

[0091] Specifically, the preset pressure value is determined based on pre-tested experimental data. When it is determined that the current pressure value is not less than the preset pressure value, the electric toothbrush 100 is controlled to continue cleaning to prevent the electric toothbrush 100 from stopping.

[0092] In the embodiment of the above-described detection brush head 50 current pressure value in this application, in step S202, the control method further includes the step of:

[0093] S2021: If the current pressure value is not less than the preset pressure value, then adjust the vibration intensity of the electric toothbrush 100 according to the current pressure value.

[0094] Specifically, by determining that the current pressure value is not less than the preset pressure value, the output frequency of the motor 60 of the electric toothbrush 100 is controlled to adjust its vibration intensity, thereby improving the cleaning ability and achieving effective cleaning of teeth.

[0095] Optionally, when the current pressure value is less than the preset pressure value, the vibration intensity of the electric toothbrush 100 can be kept constant. Alternatively, when the current pressure value is not less than the preset pressure value, the vibration intensity of the electric toothbrush 100 can be maintained at a certain level and then remain unchanged.

[0096] Example 3

[0097] like Figure 4 As shown, after the problem of accidental interruption of the electric toothbrush 100 in the mouth was solved in the above embodiment one, the goal of allowing the user to stop the electric toothbrush 100 at any time has not yet been achieved. To address the issue of the user wanting to stop the electric toothbrush 100 at any time, this application also provides the following embodiment: In step S2, after the brush head 50 moves (after the cleaning operation is started), the control method further includes the following step:

[0098] S211, Obtain the current angle value of the electric toothbrush 100.

[0099] Specifically, an attitude sensor is installed inside the electric toothbrush 100. This attitude sensor can be an acceleration or angular velocity sensor, and it is used to detect the current angle value of the electric toothbrush 100 during operation.

[0100] It is understandable that the current angle value of the electric toothbrush 100 can be obtained in real time or periodically, and the periodic interval can be set according to actual needs.

[0101] S212: If the current angle value is within a preset angle threshold and the current voltage value is less than the preset voltage value, then control the electric toothbrush 100 to turn off or stop cleaning.

[0102] Specifically, the preset angle threshold is determined based on pre-detected experimental data. Optionally, the preset angle threshold range is 75 degrees to 105 degrees. The attitude sensor is used to detect the angle value of the electric toothbrush 100 during operation. When the angle value of the electric toothbrush 100 is within the preset angle threshold range, the electric toothbrush 100 is controlled to stop working, enabling it to stop at any time based on its angle in three-dimensional space, even without control buttons. For example, when the user holds the electric toothbrush 100 vertically, its current angle value is 90 degrees, falling within the range of 75 to 105 degrees. Simultaneously, if the detected current voltage value is less than a preset voltage value, the processor 102 or controller inside the electric toothbrush 100 will control it to stop cleaning.

[0103] like Figure 5 As shown, before obtaining the current voltage value of the electric toothbrush in step S1, the control method further includes the following steps:

[0104] S211: Obtain the current angle value of the electric toothbrush 100. The method for obtaining this value is the same as that used in Embodiment 3 above.

[0105] S213: If the current angle value is not within the preset angle threshold, the electric toothbrush 100 is controlled to start, and the electric toothbrush 100 does not perform cleaning work at this time.

[0106] Specifically, for example, when a user wants to start the electric toothbrush 100, if the user holds the electric toothbrush 100 horizontally, the current angle of the electric toothbrush 100 is 180 degrees, which is not within the range of 75 degrees to 105 degrees. In this case, the processor 102 or controller inside the electric toothbrush 100 controls the electric toothbrush 100 to start working, thereby achieving the function of Embodiment 1. Of course, the user can also hold the electric toothbrush 100 at an angle of 22 degrees, 45 degrees, 60 degrees, or 70 degrees to the horizontal plane, as long as it is not within the range of 75 degrees to 105 degrees.

[0107] It is understood that the sequence number of each step in the above embodiments does not imply the order of execution. The execution order of each process should be determined by its function and internal logic, and should not constitute any limitation on the implementation process of the embodiments of this application.

[0108] Example 4

[0109] like Figure 6 and Figure 7 As shown, an embodiment of this application provides a control device 104 for an electric toothbrush, including a first acquisition module 10, a first control module 20, a detection module 30, and a second control module 21.

[0110] The first acquisition module 10 is used to acquire the current voltage value of the electric toothbrush 100;

[0111] The first control module 20 is used to control the electric toothbrush 100 to start cleaning if the current voltage value is not less than the preset voltage value.

[0112] The detection module 30 is used to detect the brushing area of ​​the brush head 50 in the human oral cavity during the cleaning process of the electric toothbrush.

[0113] The second control module 21 is used to control the electric toothbrush 100 to continue cleaning if the brushing area is located in a preset area. Correspondingly, the second control module 21 is also used to control the electric toothbrush 100 to stop cleaning if the brushing area is not located in the preset area and the current voltage value is less than the preset voltage value.

[0114] like Figure 7 As shown, the second control module 21 is also used to control the first acquisition module 10 to pause after the brush head 50 moves, or to control the first acquisition module 10 to start, and to control the electric toothbrush 100 to continue cleaning.
