Detailed Description

In order to make the technical means, creation features, achievement purposes and functions of the present invention easy to understand, the present invention is further described below with reference to the following embodiments.

Fig. 1 is a schematic view of the overall appearance of the utility model, which comprises a brush head 1, a brush handle 2, a display screen 3, a memory button 4, an acceleration button 5 and a deceleration button 6. The brush head 1 is connected with the brush handle 2, is of a detachable structure and is used for cleaning teeth, and the brush head 1 can be replaced periodically; the display screen 3 is fixed on the outer side surface of the brush handle 2 and is connected with the internal control panel 8 of the electric toothbrush, so that the current working frequency, electric quantity, service time and the like of the electric toothbrush can be displayed, and a user can conveniently check various parameters; the acceleration button 5 can steplessly adjust the working frequency and improve the working frequency, the deceleration button 6 can steplessly adjust the working frequency and reduce the working frequency, a user can adjust the working frequency according to the self requirement, the best using frequency can be memorized through the memory button 4, and repeated adjustment in the next use process is avoided.

Fig. 2 is a detailed schematic diagram of the structure of the present invention, which includes a brush head 1, a brush handle 2, a display screen 3, a memory button 4, an acceleration button 5, a deceleration button 6, a power supply 7, a control panel 8, a signal transmission line 9, a sensor 10, a magnetic steel 11, and a motor 12. Inside power 7, control panel 8 and motor 12 all were fixed in brush holder 2, power 7 was used for control panel 8's power supply, and control panel 8 can make motor 12 operate, and motor 12 drives brush head 1 vibration, reaches the effect of clean tooth, and the rotational frequency of motor 12 is exactly electric toothbrush's operating frequency. The control panel 8 can change the rotational speed of motor 12 through adjusting PWM duty cycle, and the maximum rotational speed and minimum rotational speed have been set for in advance, and maximum rotational speed can prevent to cause the injury to the tooth when the frequency is too high, and minimum rotational speed can avoid the too low cleaning effect of frequency not good. The acceleration button 5 is connected with the control panel 8, signals are input to the control panel 8, the PWM duty ratio is changed, the working frequency of the electric toothbrush is improved, and when the rotating speed of the motor 12 reaches the maximum rotating speed, the rotating speed is not changed; the speed reduction key 6 is connected with the control panel 8, signals are input into the control panel 8, the PWM duty ratio is changed, the working frequency of the electric toothbrush is reduced, and when the rotating speed of the motor 12 reaches the minimum rotating speed, the rotating speed is not changed any more. Because the rotating speed of the motor 12 is regulated by the PWM duty ratio, the working frequency is regulated steplessly by the accelerating key 5 and the decelerating key 6, when the most comfortable frequency is regulated, the frequency can be stored in the control board 8 by the memory key 4, and the electric toothbrush directly works at the frequency when being started next time. The magnetic steel 11 is fixed on the shaft of the motor 12 and rotates with the motor 12. The sensor 10 may be a hall sensor, and the sensor 10 is fixed inside the brush holder 2 and close to the magnetic steel 11. Every time the magnetic steel 11 rotates a circle, the magnetic field inside the sensor 10 changes once, the signal transmission line 9 can send the signal output by the sensor 10 to the control panel 8, the control panel 8 calculates the working frequency of the electric toothbrush, and the display screen 3 displays the working frequency in real time. Therefore, when the acceleration key 5 and the deceleration key 6 adjust the working frequency, the user can directly see the current frequency on the display screen 3, and better experience is obtained.

Above only the utility model discloses an it is preferred embodiment, the utility model discloses a scope of protection not only limits in above-mentioned embodiment, and the all belongs to the utility model discloses a technical scheme under the thinking all belongs to the utility model discloses a scope of protection. It should be noted that, for those skilled in the art, a plurality of modifications without departing from the principle of the present invention should be considered as the protection scope of the present invention.
