Vibrating electric toothbrushes can clean teeth highly efficiently by generating high-frequency vibrations in the brush head perpendicular to the length of the brush handle using a vibration motor.

[0003] Today's vibrating electric toothbrushes are limited to reciprocating high-frequency vibrations and cannot simulate a wide range of reciprocating swings along the axial direction surrounding the motor shaft; consequently, if not used correctly, they cannot efficiently clean the entire oral cavity. Furthermore, since the range of swing that the brush head can achieve along the axial direction surrounding the motor shaft varies depending on the user or the specific area of ​​the mouth to be cleaned, current vibrating electric toothbrushes suffer from a lack of user experience because they cannot meet the cleaning requirements of diverse users and different oral regions.

For example, some operations or steps may be decomposed, combined, or partially merged, so the actual execution order may change depending on the actual situation.

[0075] Modern vibrating electric toothbrushes clean teeth using a single mode of high-frequency vibration. Since they cannot simulate a large reciprocating swing along the axial direction surrounding the motor shaft, they cannot efficiently clean the entire oral cavity if not used correctly. Furthermore, modern electric toothbrushes cannot provide specific cleaning modes for different areas within the mouth, such as tongue coating or teeth, which may result in a less satisfying overall user experience.

[0076] To solve the aforementioned problem, embodiments of the present invention provide a motor control method, device, electric toothbrush, electric toothbrush control system, electric toothbrush control panel, and a readable storage medium for an electric toothbrush, so that the electric toothbrush can clean the oral cavity with high efficiency and completeness, while satisfying the requirements of various users and different parts of the oral cavity.

[0077] Referring to FIG. 1, FIG. 1 is a step flowchart illustrating a motor control method for an electric toothbrush provided in an embodiment of the present invention, and this motor control method can be applied to the motor of an electric toothbrush.

[0078] The present invention provides a motor control method for an electric toothbrush.

[0079] As illustrated in FIG. 1, the motor control method of an electric toothbrush provided in an embodiment of the present invention includes steps S100 to S400.

[0080] Step S100 acquires an operation or control signal.

[0081] Operation or control signals are commands sent from external terminals, such as mobile terminals (mobile phones, remote controls, tablet PCs), fixed terminals (servers, clouds), or the user's operation of electric toothbrush buttons or command input. Upon receiving an operation or control signal, the electric toothbrush may passively receive the operation or control command, or it may detect and determine the results obtainable based on the current situation; for example, the electric toothbrush may operate automatically by detecting the pressure and temperature of the user's hand. The operation or control signal may activate or regulate the commands of the electric toothbrush, thereby allowing adjustment of the cleaning mode, brushing time, vibration frequency, swing amplitude, swing speed, etc.

[0082] Step S200 controls the electric toothbrush motor shaft (104) to vibrate at a preset frequency opposite to a preset swing centerline.

[0083] The preset vibration frequency of the electric toothbrush may be the initial vibration frequency set at the time of factory shipment, the vibration frequency set when the power is turned on, the vibration frequency last used by the user, or the standby vibration frequency set by an adjustment command. In other words, the vibration frequency of the motor shaft (104) in the electric toothbrush can be adjusted according to usage demand. Optionally, the vibration frequency of the motor shaft (104) in the electric toothbrush can be adjusted and set between 26,000 times / minute and 70,000 times / minute.

[0084] For better understanding, when the bristles of the electric toothbrush vibrate, they may vibrate in the direction in which the length of the bristles extends, or vibrate with a fine swing amplitude in the vertical bristles length direction and the brush rod length direction. Accordingly, the motor shaft (104) of the electric toothbrush may reciprocate in one direction with a fine amplitude in the axial direction surrounding the motor shaft (104) substantially opposite to its axis. The preset swing centerline is the swing centerline vibrating from the motor shaft (104). The extension direction of the preset swing centerline coincides with the axis extension direction of the motor shaft (104) of the electric toothbrush. In actual use, the preset centerline is a vertical extension line passing through any point on the outer wall of the motor shaft. The preset swing centerline is parallel to the axis of the motor shaft (104), and the preset swing centerline coincides with the radial direction of the motor shaft (104) and the connecting line on the axis of the motor shaft (104). To facilitate assembly, a vertical cut surface is generally provided at the end of the motor shaft (104), and when the end of the motor shaft is inserted into the brush head, the direction of the vertical cut surface aligns with the direction of the brush bristles of the brush head and is installed in front of the user. The preset swing centerline is actually the vertical centerline of the motor shaft vertical cut surface.

[0085] Step S300 obtains a preset swing centerline location parameter of the electric toothbrush motor shaft (104).

[0086] There are various ways to obtain the position parameter of the pre-set swing centerline of the motor shaft (104) in an electric toothbrush. For example, when the motor shaft (104) of the electric toothbrush vibrates, the position of swinging to one side can be obtained with the maximum vibration in the left and right directions, and then, the position of the pre-set swing centerline can be obtained by calculating the center position of these two using a formula. Of course, if a mini sensor is installed on the motor shaft (104), the pre-set swing centerline position of the electric toothbrush can be obtained accurately.

[0087] Step S400 controls the preset swing centerline of the electric toothbrush motor shaft (104) to move along a preset track surrounding the axis line of the motor shaft (104).

[0088] The motor (103) of the electric toothbrush may specifically be a servo motor (103). When the electric toothbrush adopts a servo motor (103) and operates stably, it can rotate around the high-frequency vibration and axis of the motor shaft (104). When the preset swing centerline of the motor shaft (104) moves along a preset track surrounding the axis of the motor shaft (104), the preset track may rotate a certain angle in the forward direction or a certain angle in the reverse direction, or it may rotate back and forth alternately in the forward and reverse directions, so specifically, it can be selected and set according to actual needs. By controlling the preset swing centerline of the electric toothbrush to move along a preset track surrounding the axis of the motor shaft (104), the user can control the motor shaft (104) of the electric toothbrush to swing back and forth widely or rotate 360 ​​degrees around its axis by setting various preset tracks. In this way, users can simulate brushing by selecting various swing angles and modes depending on the different areas of the oral cavity to be cleaned, while simultaneously superimposing high-frequency vibrations of the brush head to clean the oral cavity highly efficiently and completely, thereby satisfying the requirements of various users and different areas of the oral cavity.

[0089] In one embodiment, referring to FIG. 2, step S300 specifically,

[0090] The method includes step S310, which, upon receiving an operation or control signal command, obtains a forward maximum vibration position parameter and a reverse maximum vibration position parameter around the axis of the motor shaft (104) of the electric toothbrush at that time through a Hall sensor, and determines a preset swing center position parameter of the electric toothbrush according to the forward maximum vibration position parameter and the reverse maximum vibration position parameter.

[0091] In actual use, the electric toothbrush may reciprocate by surrounding the axis of the motor shaft (104) opposite to a preset swing centerline. To be understood, the electric toothbrush has a vibration cycle. To facilitate the explanation of the vibration cycle, the position of the preset swing centerline is defined as zero point a, and when the electric toothbrush vibrates, a+1° is set to 1 millisecond and a-1° is set to 1 millisecond, so that moving the electric toothbrush from a-1° to a+1° position is one vibration cycle, and the vibration cycle is 2 milliseconds.

[0092] For example, to accurately obtain a preset swing center position at time Tn, the forward maximum displacement vibration position and the reverse maximum displacement vibration position within the time range of Tn-1 to Tn+1 can be obtained, and the preset swing centerline position at time Tn can be calculated through computer simulation or a formula. Specifically, the Hall sensor includes magnetic poles fixed to the circuit board and the motor shaft (104), and the magnetic poles include a North pole and a South pole, with the North pole and the South pole facing the motor shaft (104) and arranged radially symmetrically. When the motor shaft (104) vibrates, the receptor on the circuit board can detect the intensity of the two magnetic poles, obtain a curve for the magnetic signal intensity, and obtain the position of the motor shaft (104) at each time point through calculation. Unlike other methods, the method of determining the preset swing center position parameter of an electric toothbrush according to the forward maximum vibration position parameter and the reverse maximum vibration position parameter through a Hall sensor can acquire the preset swing center position parameter at any point in time of the motor axis (104) in the electric toothbrush in real time, and is more cost-effective, has a reduced error, and has higher accuracy.

[0093] In one embodiment, as illustrated in FIG. 3, step S400 specifically,

[0094] Step S410, in which, when in swing mode, the preset swing centerline of the electric toothbrush controls the preset forward and reverse reciprocating swing angles surrounding the axis line of the motor shaft, and the preset angle is greater than or equal to 10 degrees and less than or equal to 60 degrees; and / or

[0095] When in rotation mode, the preset swing centerline of the electric toothbrush is S420, which rotates 360 degrees around the axis of the motor shaft.

[0096] In swing mode, the pre-set swing centerline of the electric toothbrush controls the pre-set forward and reverse reciprocating swing angles surrounding the axis of the motor shaft (104). For example, the motor shaft (104) of the electric toothbrush surrounds its axis and first swings forward at a certain angle, then swings in the reverse direction at a different angle, and then swings forward at a certain angle again. By reciprocating in this manner, it is possible to simulate a human hand reciprocating the brush head to clean teeth. Since the swing angle of the electric toothbrush is self-set according to the user's needs, the universality of the product can be improved. To be understood, the pre-set angle refers to the angle between the pre-set swing centerline when the motor shaft (104) of the electric toothbrush swings forward to a set position and the pre-set swing centerline when the motor shaft (104) of the electric toothbrush swings in the reverse direction to a set position. Specifically, the pre-set angles are 10 degrees, 20 degrees, 25 degrees, 35 degrees, 40 degrees, 50 degrees, 60 degrees, etc. If the preset angle is less than 10 degrees, the swing range of the motor shaft (104) of the electric toothbrush becomes small, so the human hand cannot simulate a large swing to improve the cleaning effect. If the preset angle is 60 degrees or more, the swing range of the motor shaft (104) of the electric toothbrush becomes excessively large, making it easy for the brush bristles to come into contact with the gums, which reduces the brushing effect and may cause gum bleeding. By making the preset angle greater than or equal to 10 degrees or less than or equal to 60 degrees, the swing angle range of the motor shaft (104) of the electric toothbrush is reasonably set, effectively simulating that the human hand can swing a large swing to brush, thereby improving the cleaning effect while preventing damage to the gums. The preset reciprocating swing angle of the preset swing centerline of the motor shaft (104) of the electric toothbrush can be selected and set as needed and is not specifically limited here.

[0097] When in rotation mode, the pre-set swing centerline of the electric toothbrush is controlled to rotate 360 ​​degrees around the axis of the motor shaft (104), and the pre-set swing centerline of the electric toothbrush can be controlled to rotate in the forward direction, and the pre-set swing centerline of the electric toothbrush can be controlled to rotate in the reverse direction, so that this rotation direction is set when shipped from the factory and can be set to be adjustable.

[0098] The motor shaft (104) of the electric toothbrush is equipped with a swing mode and a rotation mode. In the swing mode, a preset swing center line of the motor shaft (104) of the electric toothbrush reciprocates in the forward and reverse directions while surrounding its axis. At this time, a standard toothbrush head is mounted on the motor shaft (104) of the electric toothbrush, so that the toothbrush head can reciprocate widely from left to right while surrounding the axis, thereby enabling a simulation of brushing teeth by hand and improving the cleaning effect. In the rotation mode, the preset swing center line of the motor shaft (104) of the electric toothbrush rotates 360 degrees while surrounding its axis (360). At this time, a tongue brush head is mounted on the motor shaft (104) of the electric toothbrush, so that the tongue brush head rotates 360 degrees to clean the tongue by rotating it 360 degrees. In this way, the user can choose to use the swing mode or the rotation mode according to the cleaning needs required in different parts of the oral cavity. In other words, by using only a single electric toothbrush handle and equipping it with various brush heads, diverse cleaning functions can be implemented to clean different areas of the oral cavity. Since a single item can be used in various ways, the convenience of use of the product is significantly improved, and cleaning costs for the consumer can be reduced.

[0099] The user can select swing mode or rotation mode by operating the buttons of the electric toothbrush or inputting commands, or by selecting via commands sent from an external terminal, such as a mobile terminal (cell phone, remote control, tablet PC), a fixed terminal (server, cloud), etc. Of course, the motor shaft (104) of the electric toothbrush can also actively select swing mode or rotation mode by detecting and judging the results obtained according to the current situation. For example, a magnet is installed in the tongue brush head, so the general toothbrush brush head is not a magnetic structure, and a Hall sensor is installed in the brush handle of the electric toothbrush. When the tongue brush head is mounted on the electric toothbrush, the Hall sensor detects the tongue brush head, and at this time, actively transmits a command to the control panel to control the electric toothbrush to enter rotation mode, and when the general toothbrush head is mounted on the electric toothbrush, the electric toothbrush enters swing mode.

[0100] In another embodiment, as illustrated in FIG. 4, step S200 specifically,

[0101] Step S210 is a step in which the electric toothbrush motor shaft (104) is controlled so that a constant power can reciprocate around the shaft line facing a preset swing centerline.

[0102] When the brush head of the electric toothbrush comes into contact with the teeth, reverse pressure is generated on the brush head of the electric toothbrush, and when this pressure is transmitted to the motor shaft (104) of the electric toothbrush, the force output by the motor shaft (104) of the electric toothbrush to the brush head may become uneven. The electric toothbrush motor shaft (104) is controlled so that a constant power output can reciprocate around the axis line opposite to a preset swing centerline, and when the brush head is connected to the motor shaft (104), the power of the motor (103) outputting to the brush head is constant, thereby improving comfort when brushing with the electric toothbrush and uniformity during cleaning. The specific value of the constant power output, which causes the motor shaft (104) of the electric toothbrush to reciprocate high-frequency vibration around the axis line, is set according to actual needs and is not limited thereto.

[0103] In one embodiment, the step S400 specifically includes,

[0104] In an electric toothbrush, a preset swing centerline of the motor shaft (104) is controlled so that a preset frequency reciprocates in forward and reverse directions around the axis of the motor shaft (104), wherein the ratio of the preset frequency vibrating in the motor shaft (104) to the preset frequency of the preset swing centerline of the motor shaft (104) reciprocating in forward and reverse directions around the axis of the motor shaft (104) is greater than or equal to 60.

[0105] In an electric toothbrush, by controlling the preset swing centerline of the motor shaft (104), the preset frequency reciprocates in the forward and reverse directions around the axis of the motor shaft (104), and by simulating a human hand reciprocating the brush head, the teeth can be cleaned, thereby improving the cleaning effect. The time required for the preset swing centerline of the motor shaft (104) in the electric toothbrush to move once from the maximum position where it swings in the forward direction around the axis of the motor shaft (104) to the maximum position where it swings in the reverse direction is defined as the swing cycle. The preset frequency at which the preset swing centerline of the motor shaft (104) reciprocates in the forward and reverse directions around the axis of the motor shaft (104) corresponds to the inverse of the swing cycle of the electric toothbrush.

[0106] Since the preset vibration frequency of the motor shaft (104) is generally 26,000 times / minute to 70,000 times / minute, high-frequency vibration of the brush head is realized to efficiently clean teeth and allow for a wider range of applications by the user. The ratio of the preset frequency vibrating in the motor shaft (104) to the preset frequency of the preset swing centerline of the motor shaft (104) reciprocating in forward and reverse directions around the axis of the motor shaft (104) is greater than or equal to 60, which means that the swing frequency of the motor shaft (104) is much smaller than the vibration frequency. Therefore, the swing frequency of the motor shaft (104) is relatively slow, simulating brushing by swinging with the hand, while preventing damage to the gums and teeth, thereby increasing the cleaning effect and increasing comfort during use. Selectably, the preset frequency at which the preset swing centerline of the motor shaft (104) reciprocates in the forward and reverse directions around the axis of the motor shaft (104) is approximately 100 times / minute to 400 times / minute, so that the swing frequency of the motor shaft (104) is suitable, so the user can feel more comfortable during use and clean the oral cavity highly efficiently while not damaging the gums and teeth.

[0107] In some embodiments, referring to FIG. 5, the step S200 of controlling the electric toothbrush motor shaft (104) to vibrate at a preset frequency opposite to a preset swing centerline is specifically as follows:

[0108] Step S20 is to control the motor shaft (104) of the electric toothbrush so that it vibrates at a preset vibration frequency and a preset vibration angle by being oriented toward a preset swing centerline through Field Oriented Control (FOC);

[0109] Step S400, which controls the preset swing centerline of the motor shaft (104) in the above electric toothbrush to move along a preset track surrounding the axis line of the motor shaft (104), is specifically as follows:

[0110] Step S40 is a control in which the preset swing centerline of the motor shaft (104) of the electric toothbrush rotates around the axis line of the motor shaft (104) at a preset swing angle and a preset swing speed through magnetic flux reference control.

[0111] In the present invention, the motor (103) of the electric toothbrush may specifically be a servo motor (103). By controlling the servo motor (103) by incorporating magnetic flux-based control, the adopted magnetic flux-based control controls the vibration frequency, vibration angle, swing angle, and swing speed of the motor shaft (104), thereby controlling the operation of the motor (103). As a result, the moving torque of the motor (103) is stable and noise is low, as well as having high efficiency and a rapid dynamic response. In the electric toothbrush, the vibration frequency, vibration angle, swing angle, and swing speed of the motor shaft (104) are set to be adjustable, allowing the user to select various parameters according to various usage needs, thereby increasing the versatility of the electric toothbrush.

[0112] In some other embodiments, referring to FIG. 6, prior to step S100, the following steps are

[0113] Step S10, in which an input motor calibration signal is received and the motor shaft (104) is controlled to stop vibrating, and the control of the button for the motor is released, the motor shaft (104) can rotate around its axis under the action of an external force;

[0114] Step S11, which allows sending a motor start correction signal when the motor shaft (104) is rotated to a preset swing centerline and aligned with the vertical centerline of the electric toothbrush button and the radial direction of the motor shaft (104);

[0115] Step S12 of receiving a motor start correction signal, obtaining the current position of a preset swing centerline of the motor shaft (104) in the electric toothbrush according to the motor start correction signal, and defining the current preset swing centerline position in the motor shaft (104) as a preset initial position;

[0116] It includes step S13, which involves receiving a brush head correction signal and controlling the motor shaft (104) in the electric toothbrush to rotate to a preset initial position according to the brush head correction signal.

[0117] In the present invention, the motor shaft (104) of the electric toothbrush moves along a preset track surrounding its axis, and is equipped with, for example, a reciprocating swing and a 360-degree rotation mode, and when the brush head is assembled to the motor shaft (104), the brush head is twisted so that a situation where the button and the user face each other at the same time does not occur. Before operating or adjusting the specific parameters of the motor shaft (104), if the motor shaft (104) is corrected to correct the center point position of the brush head, the accuracy when using the electric toothbrush can be improved.

[0118] The input motor calibration signal is a command sent from a charging sheet or an external terminal, for example, a mobile terminal (mobile phone, remote control, tablet PC) or a fixed terminal (server, cloud). The "input motor calibration signal command" can be sent via Bluetooth. At this time, if the toothbrush motor vibrates, the motor can stop vibrating after receiving the command, while simultaneously the electric toothbrush blocks the button function, allowing the user to manually rotate the motor shaft (104) to update the zero position of the motor shaft (104).

[0119] To facilitate assembly, a vertical cut surface is generally provided at the end of the motor shaft (104). When the end of the motor shaft (104) is inserted into the brush head, the direction of the vertical cut surface aligns with the direction of the bristles of the brush head, so that it is installed facing the user. The preset swing centerline is actually the vertical centerline of the vertical cut surface of the motor shaft (104). The user can correct the zero position of the motor shaft (104) through the vertical cut surface of the motor shaft (104). In actual operation, when the motor shaft (104) is rotated to the vertical cut surface so that it aligns with the direction of the electric toothbrush outer case button on the plane, and the vertical centerline (i.e., the preset swing centerline) on the vertical cut surface of the motor shaft (104) is aligned with the vertical centerline of the button on the plane in the radial direction of the motor shaft (104), the motor shaft (104) is placed at the zero position and can be operated more conveniently by facing the user. A motor start correction signal can be fed back via Bluetooth, and the current preset swing centerline position on the motor shaft (104) is defined as a preset initial position (i.e., zero position). When the user uses it, a brush head correction signal is sent to the electric toothbrush via an external terminal, such as a mobile phone app or mini-program. The motor shaft (104) of the electric toothbrush rotates to the zero position (preset initial position), and the direction of the bristles of the brush head aligns with the direction of the button and is installed to face the user directly. In this way, accuracy is ensured when using the electric toothbrush, and the brush head can be prevented from becoming deviated due to long-term use.

[0120] In some embodiments, referring to FIG. 7, the step S400 is specifically,

[0121] It includes step S430 of receiving a front tooth cleaning signal or a back tooth cleaning signal, and having a preset swing centerline of the electric toothbrush reciprocate in the forward and reverse directions while surrounding the axis line of the motor shaft (104) at a swing frequency corresponding to the front tooth cleaning signal or the back tooth cleaning signal.

[0122] The time required for the pre-set swing centerline of the motor shaft (104) of an electric toothbrush to move once from the maximum position where it swings in the forward direction around the axis of the motor shaft (104) to the maximum position where it swings in the reverse direction is defined as the swing period, and the swing frequency of the pre-set swing centerline of the electric toothbrush motor shaft (104) around the axis of the motor shaft (104) and this swing period are inversely related. Human teeth are classified into front teeth and back teeth, and since the position and size of the front teeth and back teeth differ, the cleaning modes actually required for the front teeth and back teeth are also different. Therefore, the swing frequency corresponding to the front tooth cleaning signal is different from the swing frequency corresponding to the back tooth cleaning signal, so if the modes are classified for different tooth areas and customized cleaning is performed, the effect of the electric toothbrush cleaning the entire oral cavity can be greatly improved. For example, the swing frequency corresponding to the front tooth cleaning signal is higher than the swing frequency corresponding to the back tooth cleaning signal. The front tooth cleaning signal or the back tooth cleaning signal may be sent by the user via a button or an external mobile terminal, or may be automatically identified and sent after being detected by the brush head. The swing frequency or swing period corresponding to the front tooth cleaning signal and the back tooth cleaning signal can be set and adjusted by the user themselves, or can continuously learn self-adaptive adjustments through the neural network of an AI algorithm.

[0123] Furthermore, the incisors and posterior teeth can be further subdivided; for example, the incisors can be divided into mid-tooth, lateral teeth, and canines, while the posterior teeth can be divided into first molars, second molars, third molars, and so on. By classifying them meticulously according to the differences between the incisors and posterior teeth, the swing frequencies corresponding to the incisor cleaning signals and posterior cleaning signals can be further subdivided. For instance, the incisor cleaning signal includes mid-tooth, lateral, and canine cleaning signals, and the posterior cleaning signal includes first, second, and third molar cleaning signals; thus, the swing frequencies corresponding to the cleaning signals of each tooth region are different.

[0124] In some other embodiments, as illustrated in FIG. 8, after step S300; before step S430, as follows:

[0125] The toothbrush head of the electric toothbrush further includes step S340, which detects a currently corresponding tooth width parameter, identifies a tooth type based on the currently corresponding tooth width parameter, and sends a corresponding front tooth cleaning signal or back tooth cleaning signal based on the currently corresponding tooth type.

[0126] The widths of the front and back teeth differ; typically, an adult's front teeth are approximately 5mm to 8mm wide, and the back teeth are approximately 8mm to 10mm wide. The tooth type can be precisely identified by the toothbrush head of the electric toothbrush detecting the current corresponding tooth width parameter, and of course, the tooth type can also be identified through other parameters. Specifically, the current tooth width parameter is detected through a collection unit, and the collected tooth width parameter is transmitted to a main control chip to identify the tooth type. A pre-set swing frequency is selected according to the tooth type. Since the swing frequency corresponding to the front tooth cleaning signal and the back tooth cleaning signal is different, the corresponding cleaning signal is sent again, and the electric toothbrush is controlled to clean at the pre-set swing frequency corresponding to the cleaning signal. Here, the collection unit is a distance sensor or a small camera, but is not limited thereto and may be other sensors.

[0127] Furthermore, prior to the step of identifying the tooth type based on the current tooth width parameter after the toothbrush head of the electric toothbrush detects the currently corresponding tooth width parameter, the following additional steps are included: that is, if an error occurs in the tooth width parameter currently corresponding to the brush head of the electric toothbrush and falls outside the normal tooth width parameter range, the information error is fed back, and the closest normal tooth width is called to compensate for the information error, thereby allowing the tooth type to be identified by the closest normal tooth width parameter. For example, if an error occurs in the collected parameter, for instance, if the collected tooth width is 1 mm, the information error is fed back to the main control chip, and the closest collected width is called. If the minimum tooth width is 5 mm, this tooth is identified as an incisor, and an incisor cleaning signal is sent, thereby compensating for the error information.

[0128] Electric toothbrushes distinguish between adults and children, and do not perform a locking function or differentiate cleaning modes when identified as being used by a child. While it is possible to determine if an adult is using the toothbrush by checking fingerprints when touching the switch button, it should be understood that fingerprints are not the only method for identifying age, and other methods such as facial recognition also exist.
