Description

[0001] This application is a divisional application of the invention patent application filed on August 24, 2021, with application number 202110977536.9 and invention title "A control method for an electric toothbrush". Technical Field

[0002] This invention relates to the field of electric toothbrush technology, and more particularly to a teeth cleaning system. Background Technology

[0003] With advancements in technology, electric toothbrushes have become increasingly powerful at cleaning, and their ease of use and storage has made them increasingly popular. Electric toothbrushes generally consist of a handle and a brush head attached to the handle. Studies have found that after cleaning teeth, if the brush head is exposed to the outside environment for an extended period, bacteria can easily grow in the humid environment. Therefore, brush heads generally need to be replaced every three to five months, and electric toothbrush brush heads are relatively expensive.

[0004] To extend the lifespan of the brush head, some manufacturers have added a toothbrush cover to electric toothbrushes. The toothbrush cover not only isolates the brush head from the outside world but also sterilizes it. However, since the brush cover is a separate part, users may forget to perform this operation, making the toothbrush cover a rather useless feature. Summary of the Invention

[0005] To address the shortcomings of the aforementioned technologies, this invention provides a control method for controlling an electric toothbrush, which allows the brush head to retract automatically without requiring manual control by the user, thus increasing convenience.

[0006] On one hand, the present invention provides a control method for an electric toothbrush, including...

[0007] Receive / acquire a first signal emitted by a first signal generator located at the bottom of the toothbrush;

[0008] The brush head is controlled to move from the use position to the storage position according to the first signal.

[0009] Optionally, the controller is configured to control the brush head to move from the storage position to the use position in response to a second signal emitted by the first signal generator when the bottom wall leaves the placement surface.

[0010] Optionally, a second signal generator is disposed on the side wall of the housing, and the controller is configured to control the movement of the brush head between the storage position and the use position in response to a signal emitted by the second signal generator.

[0011] Optionally, the first signal generator has an enabled state and a disabled state. When the first signal generator is in the disabled state, the first signal generator does not emit a signal or the controller does not receive a signal emitted by the first signal generator.

[0012] On the other hand, the present invention also provides a control method for an electric toothbrush, including...

[0013] Receive / acquire a first signal emitted by a first signal generator located at the bottom of the toothbrush;

[0014] Receive / acquire the second signal emitted by the second signal generator;

[0015] The brush head is controlled to move from the use position to the storage position based on the first signal and the second signal.

[0016] Optionally, the controller is configured to control the brush head to move from the storage position to the use position in response to a third signal emitted by the first signal generator when the bottom wall leaves the placement surface.

[0017] Optionally, the second signal is a signal generated by the second signal generator after the toothbrush has been in a stationary state for a preset time.

[0018] Optionally, in response to a signal emitted by the electric toothbrush after it transitions from a stationary state to a non-stationary state, the driver is controlled to switch the brush head from a storage position to a usage position.

[0019] In another aspect, the present invention also provides a control method for an electric toothbrush, comprising:

[0020] Receive / acquire a first signal emitted by a first signal generator, wherein the first signal is a signal that the first signal generator is configured to generate after the electric toothbrush switches from a first state to a second state and a first preset time has elapsed;

[0021] The first signal controls the electric toothbrush head to switch between a use position and a storage position.

[0022] Optionally, in response to a signal emitted after the electric toothbrush switches from a non-stationary state to a stationary state and remains stationary for a first preset time, the brush head is controlled to move from the use position to the storage position.

[0023] The present invention provides a control method for an electric toothbrush, comprising: receiving / acquiring a first signal emitted by a first signal generator located at the bottom of the toothbrush; and controlling the brush head to move from a use position to a storage position according to the first signal. By employing this method, a signal generator is installed at the bottom of the toothbrush. When the bottom of the toothbrush contacts the placement surface, it is generally considered that the user's teeth cleaning work is complete. At this time, the controller automatically retracts the toothbrush, effectively preventing the brush head from being exposed to the air due to the user forgetting to operate it.

[0040] refer to Figure 2-6 , Figure 2 This is a schematic cross-sectional view of an electric toothbrush in its storage position according to one embodiment. Figure 3 This is a schematic cross-sectional view of an electric toothbrush in its use position according to one embodiment. Figure 4 This is a diagram illustrating the change in the brush head's position from its usage position to its storage position after the toothbrush is placed on the placement surface, according to one embodiment. Figure 5 This is a diagram illustrating the change in the brush head's position from its storage location to its usage location after the toothbrush is separated from the placement surface in one embodiment. Figure 6 This is a schematic diagram of an electric toothbrush in another embodiment. The embodiment shown in the figure discloses an electric toothbrush 1, which includes, but is not limited to, a housing 11, a brush head 12, and a brush handle 13 connecting the housing 11 and the brush head 12. The housing 11 is generally configured to be held in the hand, and can be cylindrical or other easily graspable shapes, without limitation here. The housing 11 generally includes a bottom wall 112 and side walls 111. The side walls 111 generally refer to the walls that the user can grasp, and the bottom walls 112 generally refer to the walls that the user does not frequently come into contact with during normal use. For a cylindrical housing 11, the side walls 111 refer to the circumferential surface of the cylindrical housing 11, and the bottom walls 112 refer to the bottom surface of the housing 11. In some embodiments, the sidewall 111 and the bottom wall 112 can be integrally formed. In other embodiments, the sidewall 111 and the bottom wall 112 can be separately provided. It is understood that the bottom wall 112 is not limited to using the same material as the sidewall 111. In addition to defining an accommodating space 113 between the bottom wall 112 and the sidewall 111, the bottom wall 112 can also have other functions or roles, such as installing electrical devices or mechanical parts such as batteries or switches. There are no limitations here.

[0041] A receiving space 113 is defined between the bottom wall 112 and the side wall 111. At least a portion of the bottom wall 112 of the housing 11 is used to support the electric toothbrush 1 on the placement surface so that the electric toothbrush 1 is in an upright state. The bottom wall 112 can be composed of multiple different structures, and the various structures do not need to be in the same plane. For example, a portion of the bottom wall 112 can be recessed inward to install some components, as long as the other parts can support the toothbrush 1. The placement surface can be a plane or a curved surface that matches the bottom wall 112, depending on the shape of the bottom wall 112 of the toothbrush 1. When the bottom wall 112 is a plane, the toothbrush 1 can be placed on any plane, and any plane can be the placement surface. When the bottom wall 112 is a curved surface, a special base may be needed to place the toothbrush 1. In this case, the placement surface on the base is adapted to the curved surface of the bottom wall 112 to ensure that the toothbrush 1 can be kept on the base.

[0042] The brush head 12 is provided with bristles for cleaning teeth. Of course, in other embodiments, the brush head 12 may not have bristles and may clean teeth entirely through fluid jetting; this is not a detailed limitation. The brush head 12 has a storage position and a usage position. In one embodiment, the storage position means the brush head 12 is completely retracted into the receiving space 113 to keep it clean when the toothbrush 1 is not in use. The housing 11 may also contain a sterilization device, such as an ultraviolet lamp or a sterilizing gas generator. The usage position means the brush head 12 is completely extended from the housing 11, allowing the user to use the electric toothbrush 1 to clean their teeth. In another embodiment, the storage position means that part of the brush head 12 is retracted into the receiving space 113; for example, the bristles are retracted, while the rest remains outside. In other embodiments, the brush head 12 may be completely outside the receiving space 113 in the storage position, requiring an additional cover to cover it and isolate it from the outside environment.

[0043] The driver 14 is used to drive the brush head 12 to move between the storage position and the use position. The driver 14 is generally a drive motor, which drives the brush rod 13 through a transmission structure, thereby moving the brush head 12. The transmission structure can be any structure, as long as it realizes the transmission function. In other embodiments, the driver 14 can also be other devices that can provide power, which is not limited here.

[0044] The electric toothbrush 1 also includes a controller configured to control the driver 14. The controller generally controls the starting and stopping of the electric toothbrush 1, and can also control the frequency of the brush head 12 by controlling the vibration motor. The controller is mounted on a circuit board and can use conventional electrical components, which will not be detailed here. The controller can also control the driver 14 to move the brush head 12 between a use position and a storage position.

[0045] In order to enable the brush head 12 to automatically retract when no one is operating it, so as to ensure that the toothbrush 1 is isolated from the outside world after use and is further disinfected.

[0046] In one specific embodiment, a first signal generator 19 is provided at the bottom wall 112. "Provided at the bottom wall 112" here can mean directly or indirectly located on the bottom wall 112, depending on the specific structure of the toothbrush 1. The first signal generator 19 can be a mechanical switch, such as a push-button switch. When the bottom wall 112 has not been in contact with any object, the switch protrudes from the bottom wall 112 and is in a first state. When the bottom wall 112 is placed on the placement surface, the switch is subjected to force and moves from the first state to a second state, generating a signal. Upon receiving the signal, the controller moves the brush head 12 from the use position to the storage position, achieving automatic storage without additional user intervention. In other embodiments, the first signal generator 19 can also be a photosensitive sensor located at the bottom wall 112. When the bottom wall 112 is placed on the placement surface, the photosensitive sensor emits a signal when it changes from a light-emitting state to a dark state. The controller then controls the brush head 12 to switch from the use position to the storage position based on the signal.

[0047] The controller is configured to receive or acquire a first signal generated by the first signal generator 19 when the bottom wall 112 approaches or contacts the placement surface, and then control the brush head 12 to move from the use position to the storage position. "The bottom wall 112 approaches or contacts the placement surface" means that when the user places the toothbrush 1, the toothbrush 1 will approach the placement surface indefinitely until the bottom wall 112 contacts it, and then the user releases their grip; the toothbrush 1 can then stand upright or remain in the storage position. This approach can be between 1mm and 10mm; the above values ​​are just examples and are not strictly limited. The first signal generator 19 only needs to generate a signal when the toothbrush approaches the placement surface. For example, a mechanical switch or a photosensitive sensor may generate a signal even before the bottom wall 112 is fully in contact with the toothbrush.

[0048] The controller is further configured to receive or acquire a second signal generated by the first signal generator 19 when the bottom wall 112 leaves the placement surface, and then control the brush head 12 to move from the storage position to the use position. For example, the first signal generator 19 is a mechanical switch or a photoelectric switch such as a photosensor. When the bottom wall 112 leaves the placement surface, it emits a second signal, and the controller is configured to respond to the second signal by controlling the brush head 12 to move from the storage position to the use position. With this configuration, when the user needs to use the electric toothbrush 1, they can simply pick it up without having to operate a button separately, which is more convenient.

[0049] Based on Embodiment 1, the electric toothbrush 1 further includes a second signal generator disposed on the side wall 111 of the housing 11. The controller is configured to receive or acquire signals generated by the second signal generator to control the brush head 12 to move between the storage position and the use position. The second signal generator is generally a manual control switch, meaning that the user can control the brush head 12 to switch between the storage position and the use position by controlling the second signal generator. This can improve the user experience and also allow for manual operation when the first signal generator 19 generates an error signal.

[0050] In a further embodiment, the first signal generator 19 has an enabled state and a disabled state. When the first signal generator 19 is disabled, it does not generate a signal or the controller does not respond to the signal generated by the first signal generator 19. This setting can adapt to some special scenarios, such as when traveling and the toothbrush 1 is packed in a travel bag, where the environment is constantly changing. By preventing the first signal generator 19 from emitting a signal or preventing the controller from responding to the signal emitted by the first signal generator 19, the brush head 12 can be prevented from arbitrarily switching between the use position and the storage position. Of course, this setting can also meet the needs of different users; for example, some users prefer manual operation.

[0051] refer to Figure 12 , Figure 12 This is a flowchart of a control method for an electric toothbrush according to one embodiment. In this embodiment, the control method for the electric toothbrush 1 includes...

[0052] Receive / acquire a first signal emitted by a first signal generator 19 located at the bottom of toothbrush 1;

[0053] The brush head 12 is controlled to move from the use position to the storage position according to the first signal.

[0054] Furthermore, the controller is configured to control the brush head 12 to move from the storage position to the use position in response to a second signal emitted by the first signal generator 19 when the bottom wall 112 leaves the placement surface.

[0055] Furthermore, a second signal generator is disposed on the side wall 111 of the housing 11, and the controller is configured to control the movement of the brush head 12 between the storage position and the use position in response to a signal emitted by the second signal generator.

[0056] Furthermore, the first signal generator 19 has an enabled state and a disabled state. When the first signal generator 19 is in the disabled state, the first signal generator 19 does not send a signal or the controller does not receive the signal sent by the first signal generator 19. Example 2

[0057] refer to Figure 1-6This embodiment discloses an electric toothbrush 1, which includes, but is not limited to, a housing 11, a brush head 12, and a brush handle 13 connecting the housing 11 and the brush head 12. The housing 11 is generally configured to be easily held in the hand, and can be cylindrical or other easily graspable shapes; no limitation is made here. The housing 11 generally includes a bottom wall 112 and side walls 111. The side walls 111 generally refer to the walls that the user can grasp, and the bottom walls 112 generally refer to the walls that the user does not frequently come into contact with during normal use. For a cylindrical housing 11, the side walls 111 refer to the circumferential surface of the cylindrical housing 11, and the bottom walls 112 refer to the bottom surface of the housing 11. In some embodiments, the sidewall 111 and the bottom wall 112 can be integrally formed. In other embodiments, the sidewall 111 and the bottom wall 112 can be separately provided. It is understood that the bottom wall 112 is not limited to using the same material as the sidewall 111. In addition to defining an accommodating space 113 between the bottom wall 112 and the sidewall 111, the bottom wall 112 can also have other functions or roles, such as installing electrical devices or mechanical parts such as batteries or switches. There are no limitations here.

[0058] A receiving space 113 is defined between the bottom wall 112 and the side wall 111. At least a portion of the bottom wall 112 of the housing 11 is used to support the electric toothbrush 1 on the placement surface so that the electric toothbrush 1 is in an upright state. The bottom wall 112 can be composed of multiple different structures, and the various structures do not need to be in the same plane. For example, a portion of the bottom wall 112 can be recessed inward to install some components, as long as the other parts can support the toothbrush 1. The placement surface can be a plane or a curved surface that matches the bottom wall 112, depending on the shape of the bottom wall 112 of the toothbrush 1. When the bottom wall 112 is a plane, the toothbrush 1 can be placed on any plane, and any plane can be the placement surface. When the bottom wall 112 is a curved surface, a special base may be needed to place the toothbrush 1. In this case, the placement surface on the base is adapted to the curved surface of the bottom wall 112 to ensure that the toothbrush 1 can be kept on the base.

[0059] The brush head 12 is provided with bristles for cleaning teeth. Of course, in other embodiments, the brush head 12 may not have bristles and may clean teeth entirely through fluid jetting; this is not a detailed limitation. The brush head 12 has a storage position and a usage position. In one embodiment, the storage position means the brush head 12 is completely retracted into the receiving space 113 to keep it clean when the toothbrush 1 is not in use. The housing 11 may also contain a sterilization device, such as an ultraviolet lamp or a sterilizing gas generator. The usage position means the brush head 12 is completely extended from the housing 11, allowing the user to use the electric toothbrush 1 to clean their teeth. In another embodiment, the storage position means that part of the brush head 12 is retracted into the receiving space 113; for example, the bristles are retracted, while the rest remains outside. In other embodiments, the brush head 12 may be completely outside the receiving space 113 in the storage position, requiring an additional cover to cover it and isolate it from the outside environment.

[0060] The driver 14 is used to drive the brush head 12 to move between the storage position and the use position. The driver 14 is generally a drive motor, which drives the brush rod 13 through a transmission structure, thereby moving the brush head 12. The transmission structure can be any structure, as long as it realizes the transmission function. In other embodiments, the driver 14 can also be other devices that can provide power, which is not limited here.

[0061] The electric toothbrush 1 also includes a controller configured to control the driver 14. The controller generally controls the starting and stopping of the electric toothbrush 1, and can also control the frequency of the brush head 12 by controlling the vibration motor. The controller is mounted on a circuit board and can use conventional electrical components, which will not be detailed here. The controller can also control the driver 14 to move the brush head 12 between a use position and a storage position.

[0062] In order to enable the brush head 12 to automatically retract when no one is operating it, so as to ensure that the toothbrush 1 is isolated from the outside world after use and is further disinfected.

[0063] In this embodiment, a first signal generator 19 is provided at the bottom wall 112. "Provided at the bottom wall 112" here can mean directly or indirectly located on the bottom wall 112, depending on the specific structure of the toothbrush 1. The first signal generator 19 can be a mechanical switch, such as a push-button switch. When the bottom wall 112 has not been in contact with any object, the switch protrudes from the bottom wall 112, and the switch is in a first state (i.e., the brush head 12 is extended). When the bottom wall 112 is placed on the placement surface, the switch is pressed, moving from the first state to the second state, thus generating a signal. Simultaneously, a second signal generator is also provided inside the electric toothbrush 1. The second signal generator can be an accelerometer or a vibration sensor, etc., without specific limitations, as long as it can emit the first signal after the electric toothbrush 1 changes from a moving state (generally the state used by the user, such as swaying left and right or vibrating) to a stationary state (remaining stationary when placed on the placement surface) and remains stationary for a first preset time. The first preset time can be a very short period, i.e., immediately after the electric toothbrush 1 comes to a stop, the second signal is emitted. The first preset time can also be a few seconds, tens of seconds, or a few minutes. Once the electric toothbrush 1 has remained stationary for a period of time, indicating that the user has completed the cleaning process, the second signal is emitted. The controller is configured to control the driver 14 to switch the brush head 12 from the use position to the storage position after receiving the first and second signals. The two signals do not need to be received in any particular order; as long as both signals are received, the controller can control the brush head 12 to switch from the use position to the storage position. Using two signals to simultaneously control the switching of the brush head 12 between the use and storage positions effectively avoids accidental operation. For example, if the user temporarily places the toothbrush 1 aside during brushing but does not clean it, retracting the brush head 12 at this time will contaminate the internal cavity. Or, if the user does not place the toothbrush 1 on the storage surface but holds it in their hand without moving it, the toothbrush 1 will automatically retract, contaminating the internal cavity. Therefore, the dual-signal control mode can not only enable the brush head 12 to automatically retract after the conditions are met, but also effectively avoid the conditions for automatic retraction being triggered erroneously, thus affecting the customer experience.

[0064] Furthermore, based on Embodiment 2, the controller is configured to control the brush head 12 to move from the storage position to the use position in response to the third signal generated by the first signal generator 19 when the bottom wall 112 leaves the placement surface. When the user needs to use the toothbrush 1 to clean their teeth and removes the toothbrush 1 from the placement surface, the first signal generator 19 sends a signal, and the controller responds to this signal to control the brush head 12 to move from the storage position to the use position. Throughout the process, the user does not need to perform any additional operations, making it more convenient.

[0065] Furthermore, based on Embodiment 2, the controller is configured to control the driver 14 to move the brush head 12 from the storage position to the use position after the second signal generator sends a fourth signal when the electric toothbrush 1 changes from a stationary state to a non-stationary state. When the user needs to use the toothbrush 1 to clean their teeth, and removes the toothbrush 1 from the placement surface, the toothbrush 1 moves, changing from a stationary state to a non-stationary state. At this time, the first signal generator 19 sends a signal, and the controller responds to this signal to control the brush head 12 to move from the storage position to the use position. Throughout this process, the user does not need to perform any additional operations, making it more convenient.

[0066] Furthermore, based on Embodiment 2, the controller is configured to drive the brush head 12 from the storage position to the use position in response to a third signal emitted by the first signal generator 19 when the bottom wall 112 leaves the placement surface and a fourth signal emitted by the second signal generator when the electric toothbrush 1 changes from a stationary state to a non-stationary state. This dual-signal control mode effectively prevents the brush head 12 from automatically extending during accidental operation (merely moving the toothbrush 1 instead of using it).

[0067] Based on Embodiment 2, the electric toothbrush 1 further includes a second signal generator disposed on the side wall 111 of the housing 11. The controller is configured to receive or acquire signals generated by the second signal generator to control the brush head 12 to move between the storage position and the use position. The second signal generator is generally a manual control switch, meaning that the user can control the brush head 12 to switch between the storage position and the use position by controlling the second signal generator. This improves the user experience and avoids the need for manual correction when the first signal generator 19 sends an erroneous signal.

[0068] Based on Embodiment 2, the first signal generator 19 has an enabled state and a disabled state. When the first signal generator 19 is disabled, it does not emit a signal or the controller does not respond to the signal emitted by the first signal generator 19. This setting can adapt to some special scenarios, such as when traveling and the toothbrush 1 is packed in a travel bag, where the environment changes frequently. By preventing the first signal generator 19 from emitting a signal or preventing the controller from responding to the signal emitted by the first signal generator 19, the brush head 12 can be prevented from arbitrarily switching between the use position and the storage position. Of course, this setting can also meet the needs of different users. For example, some users prefer manual operation.

[0069] In Embodiment 2, a control method for the electric toothbrush 1 is also provided, including:

[0070] Receive / acquire a first signal emitted by a first signal generator 19 located at the bottom of toothbrush 1;

[0071] Receive / acquire the second signal emitted by the second signal generator;

[0072] The brush head 12 is moved from the use position to the storage position according to the first signal and the second signal.

[0073] Furthermore, the controller is configured to control the brush head 12 to move from the storage position to the use position in response to a third signal emitted by the first signal generator 19 when the bottom wall 112 leaves the placement surface.

[0074] Furthermore, the second signal is a signal generated by the second signal generator after the toothbrush 1 has been in a stationary state for a preset time.

[0075] Furthermore, in response to a signal emitted by the electric toothbrush 1 after it transitions from a stationary state to a non-stationary state, the control driver 14 drives the brush head 12 to switch from the storage position to the use position. Example 3

[0076] refer to Figure 6 You can also refer to Figure 2-5 In this embodiment, the basic structure of the electric toothbrush 1 is basically the same as that in Embodiment 1, and will not be described in detail here. The difference between this embodiment and Embodiment 1 is that the electric toothbrush 1 in this embodiment is a telescopic electric toothbrush 1, specifically including: a housing 11, which defines a receiving space 113 with an opening 114; the bottom wall 112 of the housing 11 is used to support the electric toothbrush 1 to the placement surface so that the electric toothbrush 1 is in an upright state. A brush head 12 for cleaning teeth, the brush head 12 has a storage position and a use position. A driver 14 is used to drive the brush head 12 through the opening 114 to move between the storage position and the use position. A controller is configured to control the driver 14. A first signal generator 19 is disposed at the bottom wall 112; wherein, the controller is configured to receive or acquire a first signal generated by the first signal generator 19 when the bottom wall 112 approaches or contacts the placement surface and then control the brush head 12 to move from the use position to the storage position. The toothbrush 1 structure and signal generator in this embodiment can refer to the description in the above embodiments, and will not be described in detail here. Example 4

[0077] refer to Figure 6 You can also refer to Figure 2-5In this embodiment, the basic structure of the electric toothbrush 1 is basically the same as that of Embodiment 1, and will not be described in detail here. The difference between this embodiment and Embodiment 1 is that the electric toothbrush 1 in this embodiment is a telescopic electric toothbrush 1, specifically including: a housing 11, which defines a receiving space 113 with an opening 114; the bottom wall 112 of the housing 11 is used to support the electric toothbrush 1 to the placement surface so that the electric toothbrush 1 is in a stationary state. A brush head 12 for cleaning teeth, the brush head 12 has a storage position and a use position. A driver 14 for driving the brush head 12 through the opening 114 to move between the storage position and the use position. A controller configured to control the driver 14. A first signal generator 19 (e.g., ...) disposed on the bottom wall 112. Figure 6 As shown, the controller is configured to respond to a first signal emitted by the first signal generator when the bottom wall 112 approaches or contacts the placement surface. A second signal generator (not shown) is configured to emit a second signal after the electric toothbrush 1 has been stationary for a first preset time; wherein, the controller is configured to control the driver 14 to switch the brush head 12 from the use position to the storage position after receiving the first and second signals. The toothbrush 1 structure and signal generator in this embodiment can be referred to the description in the above embodiments, and will not be detailed here. Example 5

[0078] refer to Figure 1-5 , Figure 1 This is a schematic diagram of the structure of an electric toothbrush according to one embodiment. The electric toothbrush 1 shown in the figure has a basic structure (shell 11, brush head 12, driver 14, etc.) that is basically the same as that in embodiment one or two, and will not be described in detail here. In order to enable the brush head 12 to automatically retract when no one is operating it, so as to ensure that the toothbrush 1 is isolated from the outside world after use and is further disinfected.

[0079] The electric toothbrush 1 also includes a first signal generator (not shown in the figure), configured to generate a first signal after the electric toothbrush 1 has been stationary for a first preset time. The controller is configured to control the driver 14 to switch the brush head 12 from a use position to a storage position after receiving or acquiring the first signal. The first signal generator can be an accelerometer or a vibration sensor, etc., without specific limitations, as long as it can generate the first signal after the electric toothbrush 1 changes from a moving state (generally the user's state, such as swaying left and right or vibrating) to a stationary state (remaining stationary when placed on a surface) and remains stationary for a first preset time. The first preset time can be a very short period, i.e., the first signal is generated immediately after the electric toothbrush 1 comes to a stop. The first preset time can also be a few seconds, tens of seconds, or a few minutes. After the electric toothbrush 1 has remained stationary for a period of time, it indicates that the user has completed the cleaning work, and therefore, the brush head 12 can be retracted.

[0080] Building upon Embodiment 5, the controller is further configured to control the driver 14 to move the brush head 12 from the storage position to the use position after receiving or acquiring the second signal generated by the first signal generator when the electric toothbrush 1 transitions from a stationary state to a non-stationary state. When the user needs to use the toothbrush 1 to clean their teeth and removes the toothbrush 1 from the placement surface, the first signal generator emits a signal, and the controller responds to this signal by controlling the brush head 12 to move from the storage position to the use position. Throughout this process, the user does not need to perform any additional operations, making it more convenient.

[0081] Furthermore, a control button 16 is located on the side wall 111 of the housing 11. The controller is configured to control the brush head 12 to move between the storage position and the use position in response to a signal emitted by the control button 16. The second signal generator 15 is an active control switch, meaning that the user needs to actively control the change of the position of the brush head 12, thus improving convenience.

[0082] Building upon Embodiment 5, the first signal generator further includes an enabled state and a disabled state. When the first signal generator is disabled, it neither emits a signal nor receives a signal from the controller. This setting can adapt to certain special scenarios, such as when traveling and the toothbrush 1 is packed in a travel bag where the environment changes frequently. By preventing the first signal generator from emitting a signal or preventing the controller from responding to the signal emitted by the first signal generator, the brush head 12 can be prevented from arbitrarily switching between its use and storage positions. Of course, this setting can also meet the needs of different users; for example, some users prefer manual operation.

[0083] Building upon Embodiment 5, a second signal generator 15 is further provided on the bottom wall 112 of the housing 11. The controller is configured to control the brush head 12 to move from the storage position to the use position in response to a third signal emitted by the second signal generator 15 when the bottom wall 112 leaves the placement surface. The second signal generator 15 is provided on the bottom wall 112; this "provided on the bottom wall 112" can refer to a direct or indirect placement on the bottom wall 112, depending on the specific structure of the toothbrush 1. The second signal generator 15 can be a mechanical switch, such as a push-button switch. When the bottom wall 112 has not been in contact with any object, the switch protrudes from the bottom wall 112, and the switch is in a first state (i.e., the brush head 12 is in the extended state). When the bottom wall 112 is placed on the placement surface, the switch is pressed, moving from the first state to the second state, i.e., generating a signal. At this time, after receiving the signal, the controller controls the brush head 12 to move from the use position to the storage position, achieving automatic storage without requiring additional user operation. In other embodiments, the second signal generator 15 may also be a photosensitive sensor disposed on the bottom wall 112. When the bottom wall 112 is placed on the placement surface, the photosensitive sensor will emit a signal when it changes from a state with light to a state without light. The controller controls the brush head 12 to switch from the use position to the storage position according to the signal.

[0084] Based on Embodiment 5, the toothbrush further includes a second signal generator 15 disposed on the bottom wall 112 of the housing 11. The second signal generator 15 can be substantially the same as the generator in the previous embodiment, and will not be described in detail here. The second signal generator 15 is configured to emit a third signal when the bottom wall 112 leaves the placement surface; the first signal generator is configured to emit a second signal after the electric toothbrush 1 changes from a stationary state to a non-stationary state. The controller is configured to control the brush head 12 to move from the storage position to the use position after receiving or acquiring the third signal and the second signal. The dual-signal control mode can not only enable the brush head 12 to automatically retract after the conditions are met, but also effectively avoid the conditions for automatic retraction being accidentally triggered, which would affect the customer experience.

[0085] In a further embodiment, the first signal generator is configured to emit a first signal after the electric toothbrush 1 is stationary and placed substantially vertically on the placement surface for a first preset time. The preset time can be set by the user; to avoid accidental triggering, it can be set to tens of seconds or several minutes, without further detail here. Example 6

[0086] refer to Figure 1-5The electric toothbrush 1 shown in the figure has a basic structure (housing 11, brush head 12, driver 14, etc.) that is basically the same as that in Embodiment 1 or 2, and will not be described in detail here. In this embodiment, the housing 11 of the electric toothbrush 1 defines a receiving space 113 with an opening 114. The brush head 12 is used for cleaning teeth and has a storage position and a use position; the driver 14 is used to drive the brush head 12 through the opening 114 to move between the storage position and the use position; the controller is configured to control the driver 14. In this embodiment, the electric toothbrush 1 also includes a first signal generator (not shown in the figure) configured to generate a first signal after the electric toothbrush 1 has been stationary for a first preset time; wherein, the controller is configured to control the driver 14 to drive the brush head 12 to switch from the use position to the storage position after receiving or acquiring the first signal. The toothbrush 1 structure and signal generator in this embodiment can be referred to the description in the above embodiments, and will not be described in detail here. Example 7

[0087] refer to Figure 7-11 , Figure 7 This is a schematic diagram of the structure of a dental cleaning system according to one embodiment. Figure 8 This is a schematic cross-sectional view of an electric toothbrush in its storage position according to one embodiment. Figure 9 This is a schematic cross-sectional view of an electric toothbrush in its use position according to one embodiment. Figure 10 This is a diagram showing the change in the brush head's position from the usage position to the storage position after the toothbrush is placed on the base in one embodiment. Figure 11 This diagram illustrates the change in the brush head's position from its storage location to its usage location after the toothbrush is separated from the base in one embodiment. The teeth cleaning system in this embodiment includes a toothbrush 1 and a base. In this embodiment, the basic structure of the electric toothbrush 1 (shell 11, brush head 12, driver 14, etc.) is basically the same as in Embodiment 1 or 2, and will not be described in detail here. The base is used to connect to the toothbrush 1. The base can be used to hold the toothbrush 1 and also to charge it. The shape and placement of the base are not specifically limited. The base can be placed on a horizontal surface to support the toothbrush 1 or placed on a wall to support the toothbrush 1 or to charge it. Wireless charging can be used. The base can have multiple storage or charging locations simultaneously to facilitate the simultaneous storage or charging of multiple toothbrushes 1.

[0088] The toothbrush also includes a driver 14 for driving the brush head 12 to move between a storage position and a use position. The driver 14 is generally a drive motor, which drives the brush arm 13 through a transmission structure, thereby moving the brush head 12. The transmission structure can be any structure, as long as it achieves the transmission function. In other embodiments, the driver 14 can also be other devices that can provide power, which is not limited here.

[0089] The electric toothbrush 1 also includes a controller (not shown) configured to control the driver 14. The controller generally controls the starting and stopping of the electric toothbrush 1, and can also control the frequency of the brush head 12 by controlling the vibration motor. The controller is mounted on a circuit board and can use conventional electrical components, which will not be detailed here. The controller can also control the driver 14 to move the brush head 12 between a use position and a storage position.

[0090] The base 2 is used to connect to the toothbrush 1. The base 2 can be used to hold the toothbrush 1 and also to charge it. The shape and placement of the base 2 are not specifically limited. The base 2 can be placed on a horizontal surface to support the toothbrush 1 or on a wall to support or charge the toothbrush 1. Charging can be done wirelessly. The base 2 can have multiple storage or charging locations simultaneously to facilitate the simultaneous storage or charging of multiple toothbrushes 1.

[0091] refer to Figure 10-11 In order to enable the brush head 12 to automatically retract when no one is operating it, so as to ensure that the toothbrush 1 is isolated from the outside world after use and is further disinfected.

[0092] The toothbrush 1 also includes a driver 14 and a controller. The driver 14 drives the brush head 12 to move between a storage position and a use position. The controller is configured to move the brush head 12 from the use position to the storage position after the toothbrush 1 is docked to the base 2, or to move the brush head 12 from the storage position to the use position after the toothbrush 1 leaves the base 2. With this control structure, when the toothbrush 1 is placed on the base 2 or near the base 2 for charging, it indicates that the user has completed the cleaning process, and the brush head 12 can automatically move from the use position to the storage position. Alternatively, the user needs to actively control the brush head 12. After using the toothbrush 1, the brush head 12 can automatically retract into the cavity for drying and sterilization. Or, the brush head 12 may move away from the base 2, indicating that the user needs to clean their teeth; therefore, the controller moves the brush head 12 from the storage position to the use position. Using the above control method, the user does not need to actively control the brush head 12, making it more convenient to use.

[0093] Based on Embodiment 7, a first detection device 15 is provided on the toothbrush 1 (e.g., ...). Figure 7As shown, the first detection device 15 is configured to send a first signal after the toothbrush 1 is connected to the base 2. The controller responds to the first signal and controls the brush head 12 to move from the use position to the storage position. Specifically, the first detection device 15 can be a Hall sensor, and the base 2 is equipped with a magnet. When the toothbrush 1 approaches the base 2, the Hall sensor generates a signal. Upon receiving the signal, the controller controls the brush head 12 to move from the use position to the storage position. Alternatively, the toothbrush 1 can be equipped with a mechanical switch that is compatible with the structure on the base 2. When the toothbrush 1 is placed on the base 2, the mechanical switch is triggered, controlling the brush head 12 to move from the use position to the storage position. The controller can control the brush head 12 immediately. The controller is also configured to switch the brush head 12 from the use position to the storage position after the toothbrush 1 has been connected to the base 2 for a preset time. That is, the controller can also wait for a preset time before controlling the brush head 12. The preset time can be a few seconds or minutes, and the user can also set the preset time. It is also understood that the first detection device 15 can be any other structure or device capable of generating a signal after the toothbrush 1 is placed on the base 2. The toothbrush 1 also includes a second detection device for detecting whether the brush head 12 is in the use position. The toothbrush 1 also includes a third detection device for detecting whether the brush head 12 is in the storage position. When the third detection device detects that the brush head 12 is in the storage position, the controller controls the driver 14 to stop. In one embodiment, the toothbrush 1 also includes an alarm device configured to issue an alarm signal when the brush head 12 is not in the use or storage position. When the brush head 12 remains between the use and storage positions for an extended period, it indicates that the toothbrush 1 has malfunctioned, and the alarm device will issue an alarm signal. The second and third detection devices can also be Hall sensors, or other structures.

[0094] refer to Figure 11 Based on Embodiment 7, the toothbrush 1 is equipped with a first detection device 15. The first detection device 15 is configured to emit a second signal after the toothbrush 1 leaves the base 2. The controller responds to the second signal by controlling the brush head 12 to move from the storage position to the use position. The first detection device 15 can be a Hall sensor. When the toothbrush 1 leaves the base 2, the Hall sensor emits a signal, and the controller controls the brush head 12 to move from the storage position to the use position according to the signal. The toothbrush 1 also includes a second detection device for detecting whether the brush head 12 is in the use position. The toothbrush 1 also includes a third detection device for detecting whether the brush head 12 is in the storage position. When the second detection device detects that the brush head 12 is in the use position, the controller controls the driver 14 to stop. In one embodiment, the toothbrush 1 also includes an alarm device configured to emit an alarm signal when the brush head 12 is not in the use position or the storage position. When the brush head 12 remains between the use position and the storage position for an extended period, it indicates that the toothbrush 1 has malfunctioned, and the alarm device will emit an alarm signal.

[0095] Based on Embodiment 7, the toothbrush 1 is equipped with a rechargeable battery, and the controller is configured to control the brush head 12 to be in the storage position when the rechargeable battery is charging. Specifically, the base 2 is provided with charging contacts or a wireless charging coil. When the toothbrush 1 is placed on the base 2, the base 2, which is connected to the mains power, begins to charge the battery. At this time, the circuit board connected to the battery generates a charging signal, and the controller controls the brush head 12 to move from the use position to the storage position according to the charging signal. When the toothbrush 1 is removed from the base 2, the charging signal disappears, and the controller can then control the brush head 12 to move from the storage position to the use position. It can be understood that when the battery is fully charged, the charging signal will still exist, but the battery will no longer be charged. However, as long as the toothbrush 1 is connected to the base 2, this charging signal will continue to exist until the toothbrush 1 leaves the base 2.

[0096] Based on embodiment seven, the toothbrush 1 also includes a control button 16, which is configured to control the brush head 12 to switch between the usage position and the storage position.

[0097] The controller is configured to switch the brush head 12 from the use position to the storage position after the brush head 12 is in the use position and docked with the base 2. If the toothbrush 1 is already in the storage position before being placed on the base 2, then the controller does not need to issue a command to control the driver 14 to drive the brush head 12. Example 8

[0098] In this embodiment, the structure of the electric toothbrush 1 will not be described in detail; instead, the control method of the electric toothbrush 1 will be described in detail below:

[0099] This invention discloses a control method for an electric toothbrush 1, comprising:

[0100] Receive / acquire a first signal emitted by a first signal generator 19, the first signal being a signal generated by the first signal generator 19 after the electric toothbrush 1 switches from a first state to a second state and a first preset time has elapsed; control the brush head 12 of the electric toothbrush 1 to switch between the use position and the storage position according to the first signal.

[0101] In one embodiment, the first state can be that the entire toothbrush 1 is in a non-stationary state, and the second state is that the entire toothbrush 1 is in a stationary state. When the toothbrush 1 transitions from a non-stationary state to a stationary state and remains stationary for a period of time, it indicates that the user has completed the cleaning work. At this time, the first signal generator 19 generates a signal, and the controller can control the brush head 12 to switch from the use position to the storage position. In order to ensure that it is not accidentally triggered, the time that the toothbrush 1 remains in the stationary state can be set to be longer, for example, a few minutes or more than ten minutes, to give the user sufficient time.

[0102] In another embodiment, the first state can be that the brush head 12 is in a vibrating state, and the second state can be a non-vibrating state. When the brush head 12 changes from the vibrating state to the non-vibrating state and remains in a stationary state for a period of time, it indicates that the user has completed the cleaning work. At this time, the first signal generator 19 generates a signal, and the controller can control the brush head 12 to switch from the use position to the storage position. In order to ensure that it is not accidentally triggered, the time that the toothbrush 1 is in the non-vibrating state can be set to be longer, for example, a few minutes or more than ten minutes, to give the user sufficient time.

[0103] In other embodiments, the first state can be any state other than a non-stationary state or a vibration state, indicating that the user is using the toothbrush 1, such as: the battery is not charging, current is continuously output, or the pressure state of the pressure sensor on the handle of the toothbrush 1, etc., which will not be described in detail here.

[0104] In other embodiments, the first state can be a stationary state or other states that indicate the toothbrush 1 is not in use (e.g., charging state). The second state can be a non-stationary state or other states that indicate the toothbrush 1 is about to be used (e.g., non-charging state). In this case, the first signal generator 19 sends a signal, and the controller controls the brush head 12 to switch from the storage position to the use position. During this process, the user does not need to perform any additional operations, making it more convenient to use. Example 9

[0105] In this embodiment, the structure of the electric toothbrush 1 will not be described in detail; instead, the control method of the electric toothbrush 1 will be described in detail below:
