The foregoing and other features, aspects, and advantages of the present utility model will become more apparent from the following detailed description of the preferred embodiments, which proceeds with reference to the accompanying drawings. While the utility model may be susceptible to further details of technical means and effects for achieving the desired purpose, there is shown in the drawings a form a further part hereof, and in which is shown by way of illustration and not by way of limitation, certain well-known elements of the utility model. Like elements are denoted by like reference numerals throughout the various figures. For purposes of clarity, the various elements in the drawings are not necessarily drawn to scale.

Fig. 1 is a schematic structural view of a full automatic toothbrush trigger device according to a first embodiment of the present utility model. As shown in fig. 1, the present embodiment provides a full-automatic toothbrush trigger device, which includes a motor 10 and a light sensor 20; the motor 10 is connected with the brush head 40 through the brush head shaft 30, and when the brush head 40 is stressed, the brush head 40, the brush head shaft 30 and the motor 10 swing together; the light sensor 20 is disposed in the handle and electrically connected to the motor 10, and controls the motor 10 to be turned on or off according to the approaching or separating motion between the motor 10 and the housing 50.

In an embodiment, the light sensor 20 includes a light emitter and a light receiver, the light emitter emits detection light, the light receiver receives detection light with different light intensities according to the approaching or separating motion between the motor 10 and the housing 50, and then an induced voltage generated according to the light intensity of the detection light changes, and a switching signal can be generated according to the induced voltage to control the motor 10 to be turned on or off.

In one embodiment, the motor 10 is controlled to be turned on or off by the voltage comparison circuit according to the comparison between the induced voltage generated by the light receiver and the threshold voltage.

In one embodiment, the light sensor 20 is provided with at least two light emitters and at least two light receivers, the emitters and light receivers being arranged in pairs. Therefore, through the transmitters and the light receivers of a plurality of pairs, the induced voltages generated by the light receivers can be compared with the corresponding threshold voltages, and when the comparison results of judging that the brush head is pressed by force or judging that the brush head is not pressed by force are obtained, the motor 10 is controlled to be started or closed, so that false triggering is avoided.

In one embodiment, both the light emitter and the light receiver of the light sensor 20 are disposed on the board surface of the circuit board 60. In one embodiment, the optical transmitter and optical receiver are mounted, such as soldered, to the surface of the circuit board 60.

In one embodiment, the light sensor 20 is disposed on one side of the brush face of the brush head 40 and on the side of the motor 10.

Specifically, as shown in fig. 1, in the fully automatic toothbrush trigger device of the present embodiment, when the brush head 40 is subjected to an external force, the brush head 40 is displaced, and the brush head 40 is connected to the motor 10 through the brush head shaft 30, so that the brush head 40, the brush head shaft 30 and the motor 10 swing together, and the light sensor 20 controls whether the motor 10 is started or not according to the detected approaching or separating motion between the motor 10 and the housing 50. For example, in fig. 1, three groups of light emitters and light receivers are disposed on the circuit board 60 in the light sensor 20, when the brush head 40 is acted by an external force, the circuit board 60 disposed on the side surface of the motor 10 will undergo micro deformation, so that one end of the circuit board 60, which is close to the brush head 40, is relatively far away from the inner wall, and one end, which is far away from the brush head 40, is relatively close to the inner wall, so that the angle of the light signal emitted by the light emitter reflected by the inner wall of the toothbrush to the light receiver changes, accordingly, the light intensity of the received detection light changes, the induced voltage generated according to the light intensity of the detection light changes, and the motor 10 can be controlled to be turned off or controlled according to the induced voltage generated switch signal. For example, the motor 10 may be controlled to turn on or off, i.e., turn on or stop vibration, respectively, by a voltage comparison circuit based on a comparison of the induced voltage generated by the light receiver with a threshold voltage. Also for example, the change in the light signal from the plurality of different position sensors can be used to resolve the current direction and degree of force applied to the brush head 40 and to provide an automatic start and stop switch signal for the toothbrush; for example, motor 10 may be controlled to turn on based on the induced voltages generated by both light receivers near brushhead 40 being less than the corresponding threshold voltages. Thus, the present embodiment can be used to automatically turn the motor 10 on and off, achieving full automatic operation of the full automatic toothbrush.
