Abstract
The utility model discloses a piezoelectric stack drive formula ultrasonic toothbrush, this toothbrush mainly comprise toothbrush main part, transmission shaft, sealing washer, trembler, retaining ring, pivot, piezoelectric stack, fixing base, drive power supply, control panel. The lower end of the piezoelectric ceramic is fixedly arranged on the fixed seat, and the upper part of the piezoelectric ceramic is fixedly connected with the vibrating piece through the shaft pin; the driving power supply and the control board are fixedly arranged in the toothbrush main body and are power sources of the whole toothbrush. The utility model has the advantages that: the vibration frequency is more than 100KHz, and the cleaning effect is better; the vibration amplitude is micron-sized, and the damage to the gum is small.
Description
Technical Field
The utility model relates to an oral health product, in particular to a piezoelectric stack drive formula ultrasonic toothbrush.
Background
Most of electric toothbrushes on the market at present vibrate at high frequency through a micro motor or a magnetic suspension motor during working and then are transmitted to a toothbrush head through a transmission shaft so as to achieve the effect of cleaning teeth. The electric toothbrush has large vibration amplitude, is easy to damage gum, has a complex internal structure, is easy to damage a motor, has the highest vibration frequency within 10KHz and has a common cleaning effect.
Disclosure of Invention
The utility model discloses utilize piezoelectric stack high-frequency vibration's characteristic, provide a vibration frequency more than 100KHz, the piezoelectric stack drive formula ultrasonic toothbrush of vibration range micron order. The high frequency and low amplitude vibration enables better cleaning effect and minimal harm to gums during tooth brushing.
The piezoelectric stack driving type ultrasonic toothbrush comprises a toothbrush main body, a transmission shaft, a sealing ring, a vibrating piece, a retainer ring, a shaft pin, a piezoelectric stack, a fixing seat, a driving power supply and a control panel. The lower end of the transmission shaft is fixedly arranged at the upper part of the vibrating plate, the middle section of the transmission shaft is sealed by the sealing ring, and the upper end of the transmission shaft extends out of the toothbrush main body; the vibrating piece is fixedly arranged in the toothbrush main body and is sealed with the inner wall of the toothbrush main body through a retaining ring; the fixed seat is fixedly arranged in the toothbrush main body; the lower end of the piezoelectric ceramic is fixedly arranged on the fixed seat, and the upper part of the piezoelectric ceramic is fixedly connected with the vibrating piece through the shaft pin; the drive power supply and the control panel are fixedly arranged in the toothbrush main body and connected through an electric wire.
Drive power supply does with the control panel the utility model discloses the power supply of device. When the piezoelectric ceramic toothbrush works, the control panel sends out a driving signal, the piezoelectric stack generates high-frequency vibration after receiving a pulse signal and transmits the high-frequency vibration to the toothbrush head through the transmission shaft, and the vibration amplitude of the piezoelectric ceramic toothbrush is micron-.
Description of the drawings:
FIG. 1 is a two-dimensional structure diagram of a piezoelectric stack driven ultrasonic toothbrush
Wherein: 1. toothbrush main body 2, transmission shaft 3, sealing ring 4, vibrating piece 5, retainer ring 6, shaft pin 7, piezoelectric stack 8, fixing seat 9, driving power supply 10 and control panel
The specific implementation mode is as follows:
the embodiments are further described below with reference to the accompanying drawings.
As shown in fig. 1, the piezoelectric stack driven ultrasonic toothbrush comprises a toothbrush main body 1, a transmission shaft 2, a sealing ring 3, a vibrating plate 4, a retainer ring 5, a shaft pin 6, a piezoelectric stack 7, a fixed seat 8, a driving power supply 9 and a control board 10. The lower end of the transmission shaft 2 is fixedly arranged at the upper part of the vibrating plate 4, the middle section of the transmission shaft is sealed by the sealing ring 3, and the upper end of the transmission shaft extends out of the toothbrush main body 1; the vibrating piece 4 is fixedly arranged in the toothbrush main body 1 and is sealed with the inner wall of the toothbrush main body 1 through a retaining ring 5; the fixed seat 8 is fixedly arranged in the toothbrush main body 1; the lower end of the piezoelectric ceramic 7 is fixedly arranged on the fixed seat 8, and the upper part of the piezoelectric ceramic is fixedly connected with the vibrating piece 4 through the shaft pin 6; the driving power supply 9 and the control board 10 are fixedly arranged inside the toothbrush main body 1 and connected through an electric wire.
The driving power supply 9 and the control panel 10 are the power source of the device. When the toothbrush works, the control panel 10 sends out a driving signal, the piezoelectric stack 7 generates high-frequency vibration after receiving a pulse signal and transmits the high-frequency vibration to the toothbrush head through the transmission shaft 1, and the vibration amplitude of the high-frequency vibration is micron-scale displacement output by the piezoelectric ceramic.
