The specific embodiment
In order to make the object of the invention, technical scheme and advantage clearer,, the present invention is further elaborated below in conjunction with accompanying drawing and embodiment.Should be appreciated that specific embodiment described herein only in order to explanation the present invention, and be not used in qualification the present invention.
Fig. 1-4 shows the structure of the ultrasonic toothbrush that the embodiment of the invention provides.For the ease of explanation, only show the part relevant with the present invention.
This device comprises: CPU 1, waveform generator 3, booster circuit 2 are distributed in brush holder inside; Piezoelectric ceramics sonic generator 4 is positioned at the bristle bottom of toothbrush head 7; Power knob 5 is distributed in handle one end with model selection button 6, and toothbrush head 7 is distributed in the toothbrush other end; When toothbrush head can whole replacement; Piezoelectric ceramics sonic generator 4 is positioned on the brush holder; Replaceable part 8 is distributed in toothbrush head 7 with fluid cavity 9; And when only the bristle part was replaceable, piezoelectric ceramics sonic generator 4 was arranged in toothbrush head 7 the insides, and replaceable part is distributed in above the piezoelectric ceramics 4.
The concrete function of each several part is:
The CPU 1 that is used for control waveform generator 3 duties;
Being used to the entire circuit system provides and stablizes suitable voltage, makes the booster circuit 2 of system works in stable voltage environment;
The waveform generator 3 that is used to accept the control of CPU 1 and produces corresponding frequencies;
The duty of waveform generator mainly contains the generation of low frequency wave, the generation of high frequency waves, and the low-and high-frequency ripple produces simultaneously, circuit such as MAX038 for example, according to user's demand in good time make response.
Be used to receive the signal of waveform generator 3, and make the piezoelectric ceramics 4 of corresponding vibrations according to the frequency that waveform generator produces.
Waveform generator is a circuit, generally can be on head toothbrushes, and meeting and booster circuit 2, central processing unit 1 grade is on a circuit board.Booster circuit 2 might be used in addition, might, seen the output voltage requirement of circuit own.
In embodiments of the present invention, fluid cavity 9 should directly be connected with sonic generator 4, and not so the piezoelectric ceramics vibration does not have the space
