Embodiment 1

[0026] Such as figure 1 As shown, a kind of electric toothbrush that can monitor toothbrushing intensity of the present invention comprises a toothbrush handle 1 and a toothbrush head 2 movably connected with the toothbrush handle 1, the toothbrush handle 1 includes a casing 3, and a battery is fixedly arranged in the casing 3 4 and the electric motor 5, the electric motor 5 is provided with a motor shaft 6, the electric motor 5 is connected with the toothbrush head 2 through the motor shaft 6, the outer wall of the housing 3 is provided with a reminder light 7, the outer wall of the housing 3 The inner wall is provided with a PCB circuit board 8 , and the outer side of the electric motor 5 is provided with a sensor element 9 , and the battery 4 , electric motor 5 , indicator light 7 and sensor element 9 are all electrically connected to the PCB circuit board 8 .

[0027] When brushing teeth, the toothbrush head 2 is in contact with the teeth, the battery 4 provides the necess...

Embodiment 2

[0038] Such as figure 1As shown, the difference between the present embodiment and the first embodiment is that the inner wall of the housing 3 is provided with a bracket (not marked in the drawings), and the sensor element 9 is arranged on the bracket. When the toothbrush head 2 applies force to the electric motor 5 through the motor shaft 6, the electric motor 5 exerts force on the sensor element 9 arranged on the bracket, and then makes the sensor element 9 generate an electric signal, and the electric signal is transmitted through the FPC board 10 or a wire To the PCB circuit board 8 for data processing and analysis, the structure is simple, and the operation is simple and effective.

[0039] The rest of this embodiment is the same as the first embodiment, and will not be repeated here.

Abstract

The invention relates to the technical field of electric toothbrushes, in particular to an electric toothbrush capable of monitoring tooth brushing degree. The electric toothbrush comprises a toothbrush handle and a toothbrush head movably connected with the toothbrush handle, the toothbrush handle comprises a shell, and a battery and an electric motor are fixedly arranged in the shell; a motor shaft is arranged in the electric motor, the electric motor is connected with the toothbrush head through the motor shaft, and an indicator light is arranged on the outer side wall of the shell; a PCB circuit board is arranged on the inner side wall of the shell, a sensor element is arranged on the outer side of the electric motor, and the battery, the electric motor, the indicator light and the sensor element are electrically connected with the PCB circuit board. The electric toothbrush is reasonable and compact in design, the manufacturing cost of the electric toothbrush is reduced, the pressure detection accuracy is high, and using is convenient.

Description

technical field [0001] The invention relates to the technical field of electric toothbrushes, in particular to an electric toothbrush capable of monitoring brushing strength. Background technique [0002] The electric toothbrush mainly uses the rapid rotation or vibration of the electric motor to cause the toothbrush head to generate high-frequency vibrations, instantly decompose the toothpaste into fine foam, and deeply clean the gap between the teeth. The working principle of the existing electric toothbrush is mainly based on the structure of the magnetic levitation motor itself to realize the pressure sensing function. When the user brushes teeth with excessive pressure, the magnetic levitation motor itself deforms to adjust the vibration frequency change. However, the manufacturing cost of the magnetic levitation motor is high, the structure is complex, the space is large, and the pressure detection accuracy is low. Contents of the invention [0003] The object of th...
