Title:
BUTTON-FREE SMART ELECTRIC TOOTHBRUSH AND CONTROL METHOD THEREFOR
Document Type and Number:
WIPO Patent Application WO/2023/035589
Kind Code:
A1
Abstract:
A button-free smart electric toothbrush and a control method therefor, the electric toothbrush comprising: a handle (1) and a brush head (2) detachably mounted on the handle (1), the handle (1) and the brush head (2) being connected via a transmission shaft (3), and the handle (1) having arranged therein a motor (4) used for driving the transmission shaft (3) to drive the operation of the brush head (2); the transmission shaft (3) has disposed thereon a deformation sensing device (30) used for controlling the motor (4), one side of the transmission shaft (3) is provided with an adhesive overflow groove (31) for improving deformation sensitivity, and the deformation sensing device (30) is adhered to the adhesive overflow groove (31). By installing a deformation sensing device (30) on a transmission shaft (3), a weak deformation generated by contact and pressure between the brush head (2) and the teeth during user tooth-brushing stimulates the deformation sensing device (30), causing the deformation sensing device (30) to generate a signal to control the operation of a motor (4), thereby driving the brush head (2) to generate vibration for tooth cleaning; therefore, there is no need to provide a control button on the handle (1), thus improving the airtightness of the handle (1), improving waterproof performance, making it so that the service life of the handle (1) is not reduced due to the button wearing-out from use, and prolonging the service life of the handle (1).
