[0050] Please refer to FIG. 1 to FIG. 4 . In some embodiments of the present application, an electric toothbrush 10 proposed in the present application includes: a toothbrush head 20 and a toothbrush handle 30 .

[0051] The toothbrush head 20 is detachably connected to the toothbrush handle 30 and includes a brush head body 21, a storage element 211, and a first communication element. The storage element 211 is disposed within the brush head body 21 and is used to store data containing the identity information 212 of the brush head body 21. The first communication element 213 is used for data communication between the storage element 211 and the toothbrush handle 30.

[0052] The toothbrush handle 30 is detachable from the toothbrush head 20 and includes a handle body 31, a drive assembly 311, a microprocessor 315, and a second communication element 317. The drive assembly 311 is used to drive the transmission device 22. The microprocessor 315 is disposed within the handle body 31 and is used to read the identity information 212 stored in the storage element 211 within the toothbrush head 20. The identity information 212 is provided to the microprocessor 315 via the first communication element 213. The second communication element 317 is used for data communication between the microprocessor 315 and the toothbrush head 20. The microprocessor 315 controls whether the drive assembly 311 is in operation by reading the identity information 212.

[0053] When the toothbrush head 20 is installed on the toothbrush handle 30, the storage element 211 in the toothbrush head 20 and the microprocessor 315 in the toothbrush handle 30 are electrically connected through the first communication element and the second communication element 317, thereby establishing communication between the storage element 211 and the microprocessor 315, so that the microprocessor 315 can read the identity information 212 data in the storage element 211.

[0054] Data with the identity information 212 of the brush head body 21 is stored through the storage element 211. When the toothbrush head 20 is connected to the toothbrush handle 30 and installed in place, the first communication element 213 in the toothbrush head 20 and the second communication element 317 in the toothbrush handle 30 are electrically connected, so that data communication is carried out between the storage element 211 of the toothbrush head 20 and the microprocessor 315 of the toothbrush handle 30, and then the identity information 212 data in the storage element 211 is identified by the microprocessor 315, thereby identifying whether the toothbrush head 20 matches the toothbrush handle 30, and identifying whether the toothbrush head 20 is an authorized and legal toothbrush head 20. Only when the microprocessor 315 in the toothbrush handle 30 can identify the identity information 212 stored in the storage element 211 in the toothbrush head 20, and the identity information 212 is legitimate and authorized, will the microprocessor 315 authorize the drive assembly 311 in the toothbrush handle 30 to operate, thereby driving the bristle bundle 24 in the toothbrush head 20 to rotate around the central axis of the bristle bundle 24, thereby preventing the use of unqualified, counterfeit, or unauthorized toothbrush heads 20, thereby protecting the rights and interests of consumers and developers. In this way, the toothbrush head 20 of the electric toothbrush 10 is correctly matched with the toothbrush handle 30.

[0055] In some embodiments of the present application, the identity information 212 includes a code that complies with the communication protocol coding specification and authorization specification. The microprocessor 315 is preset with a protocol program 316, and the protocol program 316 includes coding specification information and authorization specification information.

[0056] After the microprocessor 315 establishes communication with the storage element 211 , the microprocessor 315 reads the data with the identification information 212 of the toothbrush head 20 stored in the storage element 211 .

[0057] If the microprocessor 315 fails to read the identity information 212 or does not read the identity information 212, it means that the microprocessor 315 has not successfully established communication with the storage element 211, or the corresponding identity information 212 is not stored in the storage element 211 of the toothbrush head 20, or the toothbrush head 20 does not have a storage element 211. In this case, the microprocessor 315 does not authorize the drive assembly 311 to operate, that is, the drive assembly 311 is in a stopped state, and the electric toothbrush 10 cannot start normally.

[0058] If the microprocessor 315 reads the identity information 212 but determines that the encoding specification of the read identity information 212 does not comply with the encoding specification of the communication protocol, it means that the toothbrush head 20 is not produced by the designated manufacturer. In this case, the microprocessor 315 does not authorize the drive assembly 311 to operate, that is, the drive assembly 311 is in a stopped state, and the electric toothbrush 10 cannot start normally.

[0059] If the microprocessor 315 reads the identity information 212 and determines that the encoding specification of the identity information 212 complies with the encoding specification of the communication protocol but does not comply with the authorization specification of the communication protocol, it means that the toothbrush head 20 is produced by a designated manufacturer but is not authorized for sale or use. In this case, the microprocessor 315 does not authorize the drive assembly 311 to operate, that is, the drive assembly 311 is in a stopped state, and the electric toothbrush 10 cannot start normally.

[0060] If the microprocessor 315 reads the identity information 212 and determines that the encoding specification of the read identity information 212 complies with the encoding specification and authorization specification of the communication protocol, it indicates that the toothbrush head 20 is produced by the designated manufacturer and is authorized for sale and use. In this case, the microprocessor 315 authorizes the drive assembly 311 to operate, that is, the drive assembly 311 can be controlled to perform operations such as starting, turning, speed adjustment, pausing, and stopping, and the electric toothbrush 10 can start and operate normally under operational control.

[0061] In this way, the toothbrush head 20 of the electric toothbrush 10 is correctly matched with the toothbrush handle 30. Only when the microprocessor 315 in the toothbrush handle 30 can recognize the identity information 212 data stored in the storage element 211 in the toothbrush head 20, and its identity information 212 data is legal and authorized, the microprocessor 315 will authorize the drive component 311 in the toothbrush handle 30 to operate, thereby driving the bristle bundle 24 in the toothbrush head 20 to rotate around the central axis of the bristle bundle 24, thereby preventing unqualified, counterfeit or unauthorized toothbrush heads 20 from being used, and protecting the rights and interests of consumers and developers.

[0062] In some embodiments of the present application, the first communication element 213 includes a contact member 214 electrically connected to the storage element 211. The contact member 214 is disposed at the end of the brush head body 21 that intersects with the toothbrush handle 30, and the contact member 214 is exposed from the brush head body 21. The second communication element 317 includes a probe member 318 having one end electrically connected to the microprocessor 315. The probe member 318 is disposed at the end of the brush handle body 31 that intersects with the toothbrush head 20, and the end of the probe member 318 away from the microprocessor 315 extends out of the brush handle body 311. The storage element 211 and the microprocessor 315 establish communication through the conduction between the contact member 214 and the probe member 318.

[0063] The brush head body 21 is installed on the end of the brush handle body 31 by plugging, so that the toothbrush head 20 is detachably connected to the toothbrush handle 30.

[0064] When the end of the brush head body 21 and the end of the brush handle body 31 are plugged into each other, the contact piece 214 and the probe piece 318 contact each other and are connected, and the first communication element and the second communication element 317 are electrically connected through the conduction of the contact piece 214 and the probe piece 318, thereby establishing communication between the storage element 211 and the microprocessor 315, so that the microprocessor 315 can smoothly read the identity information 212 data in the storage element 211.

[0065] If the microprocessor 315 cannot read the identity information 212 data in the storage element 211, it means that the position or model of the contact member 214 of the first communication element matches the position or model of the second communication element 317, or the toothbrush head 20 is not equipped with the first communication element. In this case, it can be determined that the toothbrush head 20 is not produced by an authorized manufacturer, and the microprocessor 315 does not authorize the drive assembly 311 to operate. In other words, the drive assembly 311 is in a stopped state, and the electric toothbrush 10 cannot start normally.

[0066] In some embodiments of the present application, there are at least four contact members 214, and the contact members 214 are arranged in a predetermined position. In some embodiments of the present application, there are at least four probe members 318, and the probe members 318 are arranged in a predetermined position. The number of probe members 318 is equal to the number of contact members 214, and the arrangement of the contact members 214 corresponds to the arrangement of the probe members 318.

[0067] By disposing at least four probe members 318 at the end of the brush handle body 31 and arranging the probe members 318 in a predetermined orientation, when the brush head body 21 and the brush handle body 31 are plugged into each other, only when all the probe members 318 are electrically connected to the contact members 214 at the end of the brush head body 21 and the serial numbers of the probe members 318 match the serial numbers of the corresponding contact members 214, can the first communication element and the second communication element 317 be successfully connected to each other, and communication between the microprocessor 315 and the storage element 211 be successfully established.

[0068] If the microprocessor 315 fails to establish communication with the storage element 211, it means that the arrangement position of the contact members 214 on the toothbrush head 20 does not correspond to the arrangement position of the probe members 318 on the toothbrush handle 30, or the arrangement order of the contact members 214 on the toothbrush head 20 does not correspond to the arrangement order of the probe members 318 on the toothbrush handle 30. In this case, it means that the toothbrush head 20 is not produced by the authorized manufacturer, or the authorized manufacturer does not produce in accordance with the authorization agreement.

[0069] Referring to Figures 1 to 3, in some embodiments of the present application, at least two identification protrusions 215 are provided at the end of the brush head body 21 that plugs into the toothbrush handle 30. At least two matching grooves 319 are provided at the end of the brush handle body 31 that plugs into the toothbrush head 20. The number of matching grooves 319 is equal to the number of identification protrusions 215, the cross-sectional shape of the identification protrusions 215 matches the cross-sectional shape of the matching grooves 319, and the arrangement of the identification protrusions 215 corresponds to the arrangement of the matching grooves 319.

[0070] During the insertion of the brush head body 21 and the brush handle body 31, if the number of identification protrusions 215 is equal to the number of matching grooves 319, the arrangement of the identification protrusions 215 corresponds to the arrangement of the matching grooves 319, and the shape of the identification protrusions 215 matches the shape of the matching grooves 319, then the brush head body 21 and the brush handle body 31 can be inserted smoothly. If at least one of the number, arrangement, and shape of the identification protrusions 215 and the matching grooves 319 does not match, the brush head body 21 and the brush handle body 31 cannot be inserted smoothly. This indicates that the toothbrush head 20 is not produced by an authorized manufacturer, or the toothbrush head 20 produced is not authorized, thereby further highlighting the identification feature of the toothbrush head 20. After the brush head body 21 and the brush handle body 31 are successfully inserted, the identification protrusions 215 are embedded in the matching grooves 319, thereby improving the structural strength of the insertion point between the brush head body 21 and the brush handle body 31.

[0071] In some embodiments of the present application, the brush head body 21 includes a brush head housing 216, a transmission device 22, an input shaft 222, bristle bundles 24, and a linkage device 23. The transmission device 22 is mounted within the brush head housing 216. The input shaft 222 is used to transmit external power to the transmission device 22 and is in driving connection with the transmission device 22. There is at least one bristle bundle 24, and the bristle bundle 24 extends outward from the outer surface of the brush head housing 216. The linkage device 23 is in driving connection with the transmission device 22, and the linkage device 23 drives each bristle bundle 24 to rotate relative to the brush head housing 216.

[0072] When the toothbrush head 20 and the toothbrush handle 30 are successfully matched, the driving assembly 311 can operate normally and be controlled normally.

[0073] The drive assembly 311 is disposed within the handle body 31 of the toothbrush handle 30 and is used to drive the transmission device 22 within the brush head body 21 of the toothbrush head 20. The rotational kinetic energy of the drive assembly 311 is transmitted to the transmission device 22 via the input shaft 222. The transmission device 22 then drives the linkage device 23, thereby driving each bristle bundle 24 to rotate relative to the brush head housing 216. The rotation of each bristle bundle 24 cleans the teeth, thereby improving the cleaning effect. The independent rotation of the multiple bristle bundles 24 allows the teeth's crevices and recesses to be effectively cleaned during the cleaning process, further improving the cleaning effect of the electric toothbrush 10.

[0074] In some embodiments of the present application, the linkage device 23 includes at least one bristle mounting member 231, each bristle mounting member 231 is mounted with at least one bristle bundle 24, and adjacent bristle mounting members 231 are linked to each other. Kinetic energy is transmitted to the transmission device 22 via the input shaft 222, thereby driving each bristle mounting member 231 to rotate around its respective central axis, thereby causing the bristle bundle 24 to rotate along the central axis of the bristle mounting member 231. In this way, the bristle mounting member 231 is driven to rotate around its central axis by the drive assembly 311, thereby driving the bristle bundle 24 to rotate around the central axis of the bristle mounting member 231.

[0075] After the linkage 23 is driven by the transmission 22, each bristle mounting member 231 in the linkage 23 rotates independently, thereby driving the bristle bundle 24 mounted on the bristle mounting member 231 to rotate along the central axis of the bristle mounting member 231. The rotation of each bristle bundle 24 cleans the teeth, improving the cleaning effect. Furthermore, the independent rotation of the multiple bristle bundles 24 effectively cleans the gaps and recesses in the teeth during the cleaning process, further improving the cleaning effect of the electric toothbrush 10.

[0076] In some embodiments of the present application, the transmission device 22 includes at least one transmission gear 221, and adjacent transmission gears 221 mesh with each other. The transmission device 22 transmits kinetic energy through the meshing action between the transmission gears 221, thereby transmitting the kinetic energy generated by the rotation of the drive assembly 311 into the internal mechanism of the toothbrush head 20 via the input shaft 222. The kinetic energy from the drive assembly 311 is then transmitted to the linkage device 23 through the transmission device 22.

[0077] In some embodiments of the present application, there are at least two transmission gears 221, and the transmission ratio between the transmission gears 221 is a preset value. By setting the transmission ratio between the transmission gears 221 in the transmission device 22, the initial rotation speed of the bristle bundle 24 is limited, so that the rotation speed of the bristle bundle 24 is not too high and causes damage to the teeth or gums, and the rotation speed of the bristle bundle 24 is not too low and causes the teeth cleaning effect to fail to meet the expected requirements.

[0078] In some embodiments of the present application, there are at least two bristle mounting members 231, each of which is a gear member, and adjacent bristle mounting members 231 mesh with each other. The meshing action of the gear members causes the bristle mounting members 231 in the linkage device 23 to be linked to each other, and then a single transmission device 22 drives multiple bristle mounting members 231 to rotate simultaneously, thereby reducing the complexity of the internal mechanism of the toothbrush head 20 and reducing the space occupied by the internal mechanism of the toothbrush head 20, making the toothbrush head 20 more compact.

[0079] In the linkage device 23, the bristle mounting part 231 closest to the transmission device 22 is meshed with the transmission gear 221 in the transmission device 22 closest to the linkage device 23, and the transmission device 22 transmits kinetic energy to the linkage device 23 through meshing, and each bristle mounting part 231 in the linkage device 23 is a gear part and adjacent bristle mounting parts 231 are meshed with each other, and then each bristle mounting part 231 in the linkage device 23 is driven to rotate by the transmission device 22, and then the bristle bundle 24 in each bristle mounting part 231 is driven to rotate around the central axis of the corresponding bristle mounting part 231, so that the electric toothbrush 10 can achieve the teeth cleaning function.

[0080] In some embodiments of the present application, the number of bristle mounting members 231 is at least three, including an intermediate mounting member 232 and a peripheral mounting member 233, wherein the intermediate mounting member 232 is located between the peripheral mounting members 233. The intermediate mounting member 232 and the peripheral mounting member 233 are both gear members. The intermediate mounting member 232 is meshed and connected with the peripheral mounting members 233, and the rotation speed of the intermediate mounting member 232 is greater than the rotation speed of the peripheral mounting members 233. The gear diameter of the intermediate mounting member 232 is smaller than the gear diameter of the peripheral mounting member 233, so that when the linear speed is equal, the rotational angular velocity of the intermediate mounting member 232 is greater than the rotational angular velocity of the peripheral mounting member 233.

[0081] Since the bristle bundles 24 located at the periphery are more likely to contact more fragile parts such as the gums, the transmission ratio of the meshing between the peripheral mounting part 233 and the intermediate mounting part 232 is limited to make the rotation speed of the peripheral mounting part 233 lower than the rotation speed of the intermediate mounting part 232. In this way, the bristle bundles 24 installed on the intermediate mounting part 232 rotate at a relatively high speed to ensure that the teeth cleaning effect meets the expected requirements, and the bristle bundles 24 installed on the peripheral mounting part 233 rotate at a relatively low speed to achieve teeth cleaning without causing damage to fragile parts such as the gums.

[0082] In some embodiments of the present application, a first bevel gear is disposed on the end face of a transmission gear 221 closest to the input shaft 222 in the transmission device 22. The rotational axis of the first bevel gear is collinear with the rotational axis of the corresponding transmission gear 221. A second bevel gear is disposed on the end of the input shaft 222 closest to the transmission device 22. The rotational axis of the second bevel gear is collinear with the rotational axis of the input shaft 222. The input shaft 222 meshes with the transmission gear 221 in the transmission device 22 via a bevel gear connection, thereby causing a 90° change in rotational direction. This allows the transmission gears 221 in the transmission device 22 to be arranged along the rotational axis of the input shaft 222, thereby facilitating the input of rotational power and facilitating the layout of the transmission device 22.

[0083] In some embodiments of the present application, a plug-in portion 223 is provided at the end of the input shaft 22 away from the transmission device 22. The plug-in portion 223 extends from the end of the brush head body 21 and has a predetermined cross-sectional shape. The drive assembly 311 is a motor assembly 312. A connector 313 is mounted on the output end of the drive assembly 311. The end of the connector 313 away from the drive assembly 311 is provided with a connecting groove 314 having a predetermined cross-sectional shape. The cross-sectional shape of the plug-in portion 223 in the input shaft 222 matches the cross-sectional shape of the connecting groove 314, thereby ensuring that the cross-sectional shape of the input shaft 222 matches the cross-sectional shape of the connecting groove 314.

[0084] When the toothbrush head 20 and toothbrush handle 30 are connected, the insertion portion 223 of the input shaft 222 is inserted into the engagement groove 314 of the engagement member 313. The drive assembly 311 then drives the engagement member 313 to rotate, which in turn drives the input shaft 222, which in turn drives the transmission device 22, which in turn drives the linkage device 23. This transfers kinetic energy from the toothbrush handle 30 to the internal structure of the toothbrush head 20, causing each bristle bundle 24 in the toothbrush head 20 to rotate about the central axis of the bristle mounting member 231, thereby enabling the electric toothbrush 10 to perform its teeth cleaning function.

[0085] Referring to Figures 4 and 6, in some embodiments of the present application, an electric toothbrush 10 provided herein includes: a microprocessor 315, a drive component 311, an analog-to-digital converter 32, and a speed control module 33. The drive component 311 is used to provide power for the operation of the electric toothbrush 10. The analog-to-digital converter 32 is connected to the microprocessor 315 and the drive component 311, and the analog-to-digital converter 32 is used to feed back operating parameter information of the drive component 311 to the microprocessor 315. The speed control module 33 is connected to the microprocessor 315 and the drive component 311, and the speed control module 33 is used to control the operating speed of the drive component 311. Among them, the microprocessor 315 controls the operating speed of the drive component 311 through the speed control module 33 based on the operating parameter information from the analog-to-digital converter 32.

[0086] After the toothbrush head 20 and the toothbrush handle 30 are successfully plugged into each other and matched, the analog-to-digital converter 32 obtains the operating parameter information of the drive assembly 311 during the brushing process, and feeds the obtained operating parameter information back to the microprocessor 315. The microprocessor 315 sends corresponding instructions to the speed control module 33 based on the fed-back operating parameter information, and the speed control module 33 then controls the operating speed of the drive assembly 311. In this way, the electric toothbrush 10 is automatically controlled during the brushing process.

[0087] In some embodiments of the present application, the operating parameter information includes the current level of the driving assembly 311 during operation. If the current of the driving assembly 311 increases during operation, it indicates that the resistance encountered during the teeth cleaning process has increased, or a stall has occurred. In this case, the microprocessor 315 sends a deceleration instruction to the speed control module 33, thereby reducing the risk of overloading the driving assembly 311 and improving the reliability of the control system of the electric toothbrush 10.

[0088] In some embodiments of the present application, the electric toothbrush 10 provided herein further includes a motor controller 34. The driving assembly 311 includes a motor assembly 312. The motor controller 34 controls the operation of the motor assembly 312 and is connected to a microprocessor 315 and the motor assembly 312.

[0089] The motor controller 34 controls the start, pause, stop, forward rotation, and reverse rotation of the motor assembly 312. The microprocessor 315 sends instructions to the motor controller 34 based on the operating parameter information fed back by the analog-to-digital converter 32, thereby controlling the operating state of the motor assembly 312.

[0090] In some embodiments of the present application, the motor controller 34 is provided with a resettable fuse 35 .

[0091] When the driving component 311 is overloaded or short-circuited, the resettable fuse 35 is triggered, and the circuit supplied to the driving component 311 is cut off by the resettable fuse 35, thereby achieving overload protection and short-circuit protection, thereby improving the reliability and safety of the electric toothbrush 10 control system.

[0092] In some embodiments of the present application, the microprocessor 315 is pre-set with a program for controlling the working mode of the driving component 311 , and the working mode includes one or more of a gentle mode, a clean mode, and an intelligent mode.

[0093] According to the user's oral condition, user needs and cleaning time, the user can independently select the working mode of the drive component 311, so that the electric toothbrush 10 can meet the needs of the user's different oral conditions.

[0094] In some embodiments of the present application, the electric toothbrush 10 provided in the present application further includes a button module 36 , which is electrically connected to the microprocessor 315 , and the button module 36 is used to control the operating state of the drive component 311 and the switching of the working mode.

[0095] During the toothbrushing process, the user can press the button module 36 to select the working mode of the electric toothbrush 10 and control the operating state of the driving component 311, thereby improving the controllability of the electric toothbrush 10.

[0096] The microprocessor 315 can also be equipped with a remote communication module 39, which allows the user to remotely configure the operating parameters of the electric toothbrush 10, thereby enabling the electric toothbrush 10 to meet the user's personalized brushing needs. The remote communication module 39 can be a Bluetooth module, and the remote terminal can be a mobile phone. Through Bluetooth communication, the user can set the operating parameters of the electric toothbrush 10 on a mobile phone app, making operation more convenient and intelligent.

[0097] In some embodiments of the present application, the speed control module 33 is a voltage controller or a current controller.

[0098] The voltage of the driving component 311 can be adjusted by a voltage controller, thereby adjusting the operating speed of the driving component 311. The current of the driving component 311 can also be adjusted by a current controller, thereby adjusting the operating speed of the driving component 311.

[0099] Referring to Figures 4 and 7 , in some embodiments of the present application, an electric toothbrush 10 provided herein includes a microprocessor 315, a button module 36, and a counting module 37. The button module 36 is electrically connected to the microprocessor 315. The counting module 37 is electrically connected to the microprocessor 315 and is configured to detect the number of times the button module 36 is pressed and provide feedback to the microprocessor 315. The microprocessor 315 controls the rotation of the motor assembly 312 based on the number of times the counting module 37 provides feedback.

[0100] The number of times the button module 36 is pressed is detected by the counting module 37, and the number of times the button module 36 is pressed is fed back to the microprocessor 315. The microprocessor 315 controls the rotation state of the motor assembly 312 based on the number of times fed back by the counting module 37. During the brushing process, the electric toothbrush 10 is controlled so that the operating speed and direction of the electric toothbrush 10 meet the user's teeth cleaning needs.

[0101] In some embodiments of the present application, the rotation state of the motor assembly 312 includes one or more of start, forward rotation, reverse rotation, low speed, medium speed, high speed, stop, and pause.

[0102] According to the number of times the button module 36 is pressed, the rotation state of the motor assembly 312 is controlled. When the button module 36 is pressed once, the motor assembly 312 starts to rotate forward, and the microprocessor 315 records the number of times the button module 36 is pressed; when the button module 36 is pressed again, the microprocessor 315 determines that the button module 36 has been pressed twice based on the recorded number of times, and then the motor assembly 312 enters a low-speed operation state and records the number of times the button module 36 has been pressed; when the button module 36 is pressed again, the microprocessor 315 determines that the button module 36 has been pressed three times based on the recorded number of times, and then the motor assembly 312 enters a medium-speed operation state and records the number of times the button module 36 has been pressed; when the button module 36 is pressed again, the microprocessor 315 determines that the button module 36 has been pressed four times based on the recorded number of times, and then the motor assembly 312 enters a high-speed operation state and records the number of times the button module 36 has been pressed When the button module 36 is pressed again, the microprocessor 315 determines that the button module 36 has been pressed five times based on the recorded number of times, and then causes the motor assembly 312 to enter a pause state and records the number of times the button module 36 has been pressed. When the button module 36 is pressed again, the microprocessor 315 determines that the button module 36 has been pressed six times based on the recorded number of times, and then causes the motor assembly 312 to enter a stop state and records the number of times the button module 36 has been pressed. When the button module 36 is pressed again, the microprocessor 315 determines that the button module 36 has been pressed seven times based on the recorded number of times, and then causes the motor assembly 312 to reverse and start, and records the number of times the button module 36 has been pressed. This process continues in this way until the motor assembly 312 enters a stop state again, at which point the microprocessor 315 clears the recorded number of times. When the button module 36 is pressed again, the microprocessor 315 enters a new control cycle. In this way, a variety of rotation state control modes are implemented.

[0103] In some embodiments of the present application, the electric toothbrush 10 provided by the present application further includes a timer 38 . The timer 38 is electrically connected to the microprocessor 315 , and is used to detect the duration of an event and feed back to the microprocessor 315 .

[0104] The timer 38 can detect the duration of the button module 36 being pressed and feed it back to the microprocessor 315. If the microprocessor 315 detects that the duration of the button module 36 being pressed exceeds the first duration based on the duration information, it is determined that the button module 36 is pressed as a long press. In this case, the microprocessor 315 clears the recorded number of times. When the button module 36 is pressed again, the microprocessor 315 re-records the number of times the button module 36 is pressed.

[0105] The timer 38 can also be used to record the operating time of the motor assembly 312. Double-clicking the button module 36 causes the microprocessor 315 to enter the timed operation mode. When the operating time of the motor assembly 312 reaches a preset threshold, the motor assembly 312 stops rotating. The microprocessor 315 does not record the number of double-clicks. When the button module 36 is double-clicked, the microprocessor 315 clears the recorded number of times. In the timed operation mode, the microprocessor 315 can re-record the number of times the button module 36 was pressed, thereby controlling the speed, direction of rotation, and pause of the motor assembly 312 in the timed operation mode. When the operating time of the motor assembly 312 reaches a preset threshold, the motor assembly 312 stops rotating, and the microprocessor 315 clears the recorded number of times. When the button module 36 is pressed again, the microprocessor 315 enters a new control cycle.

[0106] In some embodiments of the present application, the button module 36 includes a first button 361 and a second button 362, each of which is electrically connected to the microprocessor 315. The first button 361 is used to control the rotation direction of the motor assembly 312, and the second button 362 is used to control the rotation speed of the motor assembly 312.

[0107] The first button 361 controls the rotation direction of the motor assembly 312, and the second button 362 controls the rotation speed of the motor assembly 312. Thus, the rotation direction and rotation speed of the motor assembly 312 are controlled by two buttons respectively, reducing the number of button presses and making user operation more convenient.

[0108] In some embodiments of the present application, a remote communication module 39 is connected to the microprocessor 315 , and the remote communication module 39 is used for the microprocessor 315 to communicate with a remote end.

[0109] The user can configure the operating parameters of the electric toothbrush 10 through the remote terminal, thereby making the electric toothbrush 10 meet the user's personalized brushing needs. The remote communication module 39 can be a Bluetooth module, and the remote terminal can be a mobile phone. Through Bluetooth communication, the user can set the operating parameters of the electric toothbrush 10 on the mobile phone app, making operation more convenient and intelligent. Example

[0110] In some embodiments of the present application, the present application further provides a control method, comprising the following steps:

[0111] The microprocessor 315 in the toothbrush handle 30 establishes communication with the storage element 211 in the toothbrush head 20;

[0112] The microprocessor 315 reads the data of the storage element 211;

[0113] The microprocessor 315 determines whether the data is valid. If the data is valid, the microprocessor 315 authorizes the driving component 311 to work. If the data is invalid, the microprocessor 315 does not authorize the driving component 311 to work.

[0114] The microprocessor 315 in the toothbrush handle 30 determines whether the data stored in the storage element 211 in the toothbrush head 20 is valid, thereby identifying whether the toothbrush head 20 is produced by an authorized manufacturer, thereby preventing unqualified, counterfeit or unauthorized toothbrush heads 20 from being used, and protecting the rights and interests of consumers and developers.

[0115] In some embodiments of the present application, the microprocessor 315 determines whether the data is valid by the following steps:

[0116] Determine whether the data is successfully obtained. If so, execute the next step. If not, do not authorize the driver component 311 to work.

[0117] Determine whether the data complies with the preset protocol encoding specification. If so, execute the next step. If not, do not authorize the driver component 311 to work.

[0118] It is determined whether the data complies with the preset protocol authorization specification. If so, the driving component 311 is authorized to work; if not, the driving component 311 is not authorized to work.

[0119] In some embodiments of the present application, the data is a code carrying the identity information 212 of the toothbrush head 20 .

[0120] If the microprocessor 315 fails to read the identity information 212 or does not read the identity information 212, it means that the microprocessor 315 has not successfully established communication with the storage element 211, or the corresponding identity information 212 is not stored in the storage element 211 of the toothbrush head 20, or the toothbrush head 20 does not have a storage element 211. In this case, the microprocessor 315 does not authorize the drive assembly 311 to operate, that is, the drive assembly 311 is in a stopped state, and the electric toothbrush 10 cannot start normally.

[0121] If the microprocessor 315 reads the identity information 212 but determines that the encoding specification of the read identity information 212 does not comply with the encoding specification of the communication protocol, it means that the toothbrush head 20 is not produced by the designated manufacturer. In this case, the microprocessor 315 does not authorize the drive assembly 311 to operate, that is, the drive assembly 311 is in a stopped state, and the electric toothbrush 10 cannot start normally.

[0122] If the microprocessor 315 reads the identity information 212 and determines that the encoding specification of the identity information 212 complies with the encoding specification of the communication protocol but does not comply with the authorization specification of the communication protocol, it means that the toothbrush head 20 is produced by a designated manufacturer but is not authorized for sale or use. In this case, the microprocessor 315 does not authorize the drive assembly 311 to operate, that is, the drive assembly 311 is in a stopped state, and the electric toothbrush 10 cannot start normally.

[0123] If the microprocessor 315 reads the identity information 212 and determines that the encoding specification of the read identity information 212 complies with the encoding specification and authorization specification of the communication protocol, it indicates that the toothbrush head 20 is produced by the designated manufacturer and is authorized for sale and use. In this case, the microprocessor 315 authorizes the drive assembly 311 to operate, that is, the drive assembly 311 can be controlled to perform operations such as starting, turning, speed adjustment, pausing, and stopping, and the electric toothbrush 10 can start and operate normally under operational control.

[0124] In this way, the toothbrush head 20 of the electric toothbrush 10 is correctly matched with the toothbrush handle 30. Only when the microprocessor 315 in the toothbrush handle 30 can recognize the identity information 212 data stored in the storage element 211 in the toothbrush head 20, and its identity information 212 data is legal and authorized, the microprocessor 315 will authorize the drive component 311 in the toothbrush handle 30 to operate, thereby driving the bristle bundle 24 in the toothbrush head 20 to rotate around the central axis of the bristle bundle 24, thereby preventing unqualified, counterfeit or unauthorized toothbrush heads 20 from being used, and protecting the rights and interests of consumers and developers.

[0125] On the other hand, in some embodiments of the present application, the present application further provides a control method, comprising the following steps:

[0126] The microprocessor 315 controls the driving component 311 to start operation;

[0127] Acquire and record the operating parameter information of the drive component 311 collected by the analog-to-digital converter 32;

[0128] Determine whether the operating parameters are within the expected range;

[0129] The control instruction is sent to the speed control module 33 according to the judgment result, thereby controlling the operating speed of the driving component 311.

[0130] In some embodiments of the present application, in the step of “determining whether the operating parameters are within the expected range”, the change in the resistance experienced by the bristle bundle 24 is evaluated based on the current information value.

[0131] After the toothbrush head 20 and the toothbrush handle 30 are successfully plugged in and correctly matched, the button module 36 is pressed, and the microprocessor 315 controls the drive component 311 to start operation. During the operation of the drive component 311, the operating parameter information (such as current signal information) of the drive component 311 is collected through the analog-to-digital converter 32, and the microprocessor 315 determines whether the operating parameters of the drive component 311 are within the expected range. The microprocessor 315 sends a control instruction to the speed control module 33 based on the judgment result, thereby controlling the operating speed of the drive component 311. Among them, the operating parameter can be the current size when the drive component 311 is in operation. If it is detected that the current size of the drive component 311 is too large when it is in operation, and it is evaluated that the resistance to the bristle bundle 24 increases, it is determined that the operating parameter is not within the expected range, and the microprocessor 315 sends a deceleration instruction to the speed control module 33, thereby controlling the drive component 311 to slow down.

[0132] On the other hand, in some embodiments of the present application, the present application further provides an intelligent control method, comprising the following steps:

[0133] The microprocessor 315 controls the driving component 311 to start operation;

[0134] Acquire and record the operating parameter information of the drive component 311 collected by the analog-to-digital converter 32;

[0135] Scan the recorded historical operating parameter information;

[0136] The driving component 311 is controlled to operate according to the historical operating parameter information.

[0137] After the microprocessor 315 obtains the operating parameter information (such as current signal information) fed back from the analog-to-digital converter 32, it saves the obtained operating parameter information and self-learns the user's brushing habits based on the operating parameter information of the user's previous use of the electric toothbrush 10, such as the force of the user's brushing, the force change curve, the speed of the drive component 311 and the speed change curve, etc. When the user turns on the electric toothbrush 10 to use it again, the speed and torque of the drive component 311 are intelligently controlled based on the operating parameter information of the user's previous use of the electric toothbrush 10, so as to improve the user's experience and enhance the teeth cleaning effect of the electric toothbrush 10, so that the control of the electric toothbrush 10 is more in line with the user's personalized operating habits and oral characteristics.

[0138] On the other hand, in some embodiments of the present application, the present application further provides a control method, comprising the following steps:

[0139] The microprocessor 315 queries the counting module 37 for the number of times the button module 36 is pressed;

[0140] By using the number of times information, it is determined whether the button module 36 is pressed. If the button module 36 is not pressed, the number of times information is continuously queried. If the button module 36 is pressed, the number of times information is recorded.

[0141] The rotation state of the motor assembly 312 is controlled according to the recording number information.

[0142] After the toothbrush head 20 and the toothbrush handle 30 are successfully plugged in and correctly matched, the microprocessor 315 queries the counting module 37 for the number of times the button module 36 has been pressed. If the parameter information detected by the microprocessor 315 is zero or the parameter information has not changed, it means that the button module 36 has not been pressed. If the parameter information detected by the microprocessor 315 is zero, the microprocessor 315 does not send a control instruction to control the motor assembly 312, so that the motor assembly 312 remains in a stopped state, and the microprocessor 315 continues to query the number of times information from the counting module 37. If the microprocessor 315 detects that the parameter information has not changed, the microprocessor 315 does not send a control instruction to control the motor assembly 312, so that the motor assembly 312 maintains its current state, and the microprocessor 315 continues to query the number of times information from the counting module 37.

[0143] If the microprocessor 315 finds that the number of times information has changed, it indicates that the button module 36 has been pressed. The microprocessor 315 then sends a control instruction to control the rotation state of the motor assembly 312 and records the number of times information.

[0144] In this way, the rotation state of the motor assembly 312 is controlled by querying the number of times the button module 36 is pressed.

[0145] In some embodiments of the present application, the rotation state of the motor assembly 312 includes the rotation duration. The microprocessor 315 selects to enter the timing mode based on the number of times information fed back by the counting module 37. The control method of the timing mode includes the following steps:

[0146] The microprocessor 315 receives the duration information from the timer 38 and records it;

[0147] The rotation state of the motor component 312 is controlled according to the duration information. When the recorded duration information reaches a preset threshold, the motor component 312 is controlled to stop running.

[0148] The timer 38 can detect the duration of the button module 36 being pressed and feed it back to the microprocessor 315. If the microprocessor 315 detects that the duration of the button module 36 being pressed exceeds the first duration based on the duration information, it is determined that the button module 36 is pressed as a long press. In this case, the microprocessor 315 clears the recorded number of times. When the button module 36 is pressed again, the microprocessor 315 re-records the number of times the button module 36 is pressed.

[0149] In some embodiments of the present application, the rotation state of the motor assembly 312 includes a pause. The microprocessor 315 selects to enter a pause mode based on the number of times information fed back by the counting module 37. The control method of the pause mode includes the following steps:

[0150] The microprocessor 315 controls the motor assembly 312 to stop running and records the running speed of the motor assembly 312 and the number of times the button module 36 is pressed;

[0151] Check whether the button module 36 is pressed. If the button module 36 is pressed, control the motor assembly 312 to operate again according to the operating speed recorded in the pause mode. If the button module 36 is not pressed, continue to check whether the button module 36 is pressed.

[0152] When the microprocessor 315 selects to enter the pause mode based on the number of times information is pressed, the microprocessor 315 controls the motor assembly 312 to pause and records the operating speed of the motor assembly 312 and the number of times the button module 36 is pressed. When the button module 36 is pressed again, the motor assembly 312 is controlled to operate again at the operating speed recorded in the pause mode, and the number of times the button module 36 is pressed this time is not recorded in the cumulative record, so that the user can control the rotation state of the electric toothbrush 10 according to the number of times rule.

[0153] In some embodiments of the present application, after the microprocessor 315 controls the rotation state of the motor assembly 312 according to the number of times feedback by the recording and counting module 37, the following steps are further included:

[0154] The microprocessor 315 queries whether the button module 36 is pressed and the pressing duration;

[0155] If the button module 36 is pressed and the pressing time does not exceed the first time, the microprocessor 315 controls the motor assembly 312 to enter the next rotation state;

[0156] If the button module 36 is pressed and the pressing time exceeds the first time length, the microprocessor 315 clears the recorded number of times information;

[0157] If the button module 36 is not pressed, the microprocessor 315 continues to query whether the button module 36 is pressed.

[0158] The timer 38 can detect the duration of the button module 36 being pressed and feed it back to the microprocessor 315. If the microprocessor 315 detects that the duration of the button module 36 being pressed exceeds the first duration based on the duration information, it is determined that the button module 36 is pressed as a long press. In this case, the microprocessor 315 clears the recorded number of times. When the button module 36 is pressed again, the microprocessor 315 re-records the number of times the button module 36 is pressed.
