Example two

Referring to fig. 1-6, the present embodiment discloses an electric toothbrush 1, the toothbrush 1 including but not limited to a housing 11, a head 12, a stem 13 connecting the housing 11 and the head 12. The housing 11 is generally configured to be hand-grippable, and may be cylindrical or other convenient gripping shape, without limitation. The housing 11 generally includes a bottom wall 112 and a side wall 111. The side wall 111 generally refers to a wall that can be grasped by a user, the bottom wall 112 generally refers to a wall that is not frequently touched by a user during normal use, and for a cylindrical housing 11, the side wall 111 refers to a circumferential surface of the cylindrical housing 11, and the bottom wall 112 refers to a bottom surface of the housing 11. In some embodiments, the side wall 111 and the bottom wall 112 may be integrally formed, and in other embodiments, the side wall 111 and the bottom wall 112 may be separately formed, it is understood that the bottom wall 112 is not limited to be made of the same material as the side wall 111, and the bottom wall 112 may have other functions or functions, such as installing electrical devices or mechanical elements, such as a battery or a switch, besides the bottom wall 112 and the side wall 111 defining the accommodating space 113, and the like, without limitation.

In the present embodiment, a first signal generator 19 is provided at the bottom wall 112. The arrangement at the bottom wall 112 may be directly or indirectly arranged at the bottom wall 112, depending on the specific structure of the toothbrush 1. The first signal generator 19 may be a mechanical switch, such as a push switch, which protrudes from the bottom wall 112 when the bottom wall 112 does not contact any object, and is in a first state (i.e. the brush head 12 is in an extended state), and when the bottom wall 112 is placed on the placement surface, the switch is pressed and moves from the first state to a second state, and a signal is generated. Meanwhile, the electric toothbrush 1 is further provided with a second signal generator, which may be an acceleration sensor or a vibration sensor, and the second signal generator is not limited in detail herein, as long as the electric toothbrush 1 keeps a first preset time after changing from a motion state (generally, a state used by a user, such as left-right shaking or vibration) to a static state (keeps static when being placed on the placement surface), and then sends out the first signal. The first preset time may be a very short time, and the second signal is immediately sent out after the electric toothbrush 1 is still, and the first preset time may also be several seconds, several tens of seconds or several minutes, and when the electric toothbrush 1 is still or in a state for a while, it indicates that the user has finished cleaning, the second signal is sent out. 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 upon receiving the first signal and the second signal. After the controller receives the two signals, the two signals can be out of sequence, only the two signals need to be received, and then the controller can control the brush head 12 to be switched from the using position to the containing position. Adopt two signals simultaneous control brush head 12 in the switching of using position and storage position, can effectively avoid the maloperation, for example, the user puts toothbrush 1 on one side temporarily in the process of brushing teeth, but does not clear up, if withdraw brush head 12 this moment, can cause the pollution to the cavity of inside. Or the user does not put the toothbrush 1 on the placing surface, but holds the toothbrush 1 by hand, but does not move the toothbrush 1, so that the toothbrush 1 is automatically retracted at the moment, and the cavity inside is polluted. Therefore, by adopting a double-signal control mode, the brush head 12 can be automatically recovered after meeting the conditions, and the condition error triggering of automatic recovery can be effectively avoided to influence the customer experience.

Further, on the basis of the second embodiment, 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 generated by the first signal generator 19 when the bottom wall 112 is away from the placing surface. When the user need use toothbrush 1 to clean teeth, when taking off toothbrush 1 from the surface of placing, at this moment, first signal generator 19 signals, and the controller responds to this signal, and control brush head 12 removes to the position of use from accomodating, and at whole in-process, the user need not be carrying out extra operation, and is more convenient.

Further, on the basis of the second embodiment, the controller is configured to control the driver 14 to drive the brush head 12 to move from the storage position to the use position in response to a fourth signal emitted by the second signal generator after the electric toothbrush 1 is in the non-stationary state from the stationary state. When the user need use toothbrush 1 to clean teeth, when taking off toothbrush 1 from the face of placing, this moment, toothbrush 1 takes place to remove, and at this moment, toothbrush 1 becomes non-quiescent condition from quiescent condition, and first signal generator 19 signals, and the controller responds to this signal, and control brush head 12 moves to the position of use from the storage position, and at whole in-process, the user need not carry out extra operation, and is more convenient.

Further, on the basis of the second embodiment, the controller is configured to drive the brush head 12 to move from the storage position to the use position in response to a third signal from the first signal generator 19 when the bottom wall 112 is away from the placement surface and in response to a fourth signal from the second signal generator when the electric toothbrush 1 is from the rest state to the non-rest state. By adopting a double-signal control mode, the automatic extension of the brush head 12 during misoperation (only moving the toothbrush 1 instead of using) can be effectively avoided.

On the basis of the second embodiment, the electric toothbrush 1 further comprises a second signal generator disposed at the side wall 111 of the housing 11, and the controller is configured to receive or acquire a signal 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, that is, the user can control the brush head 12 to switch between the storage position and the use position by controlling the second signal generator, so that the operation experience can be increased, and the artificial correction can be avoided when the first signal generator 19 generates an error signal.

On the basis of the second embodiment, the first signal generator 19 has an enabled state and a disabled state, and when the first signal generator 19 is in the disabled state, the first signal generator 19 does not emit a signal or the controller does not respond to the signal emitted by the first signal generator 19.
