Accomplish more to simplify, it is on service life, thus more difficult bad because the service life of micro machine is longer than magnetic suspension motor, than
Magnetic suspension acoustic power toothbrush economy is again durable；The resonance electric toothbrush of production and processing cost and the prior art is compared, not
Increase, but performance improves very much；The resonance electric toothbrush of the prior art is because toothbrush sleeve is connected in plastic shaft, the service life
Can be short, the time has grown cooperation precision can be far short of what is expected, and noise is gradually increased, and the impact of performance reduces, and the utility model can be solved obviously
These problems, acoustically, toothbrush head rod can be done thin and light, and the amplitude of fluctuation of such bristle will increase, to the clear of tooth
Clean effect is more preferable, and appearance seems more attractive, has more people's reasons in this way and uses, and brings material benefit to more people and useful
Durable electric toothbrush again.
When installation, in motor cabinet 3, eccentric hammer pitman shaft B9 is directly attached on motor shaft micro machine 2, critical to match；Cone
Shape eccentric hammer 10 and conical eccentric are hammered anti-skidding detent 903 into shape and are spliced, and detent will be bonded；Load onto the machine of eccentric hammer swinging axle B11, toothbrush
Body 11, toothbrush handle 7 is on eccentric hammer swinging axle B11.
Working principle: micro machine 2 rotates, and drives eccentric hammer pitman shaft B9, and conical eccentric hammer 10 is driven to turn-take swing, then
Amplitude of fluctuation is transmitted on eccentric hammer swinging axle B11, then is transmitted on the bristle of brush head 8 through toothbrush handle 7, the brush of brush head 8 is made
Hair swings to realize the effect of electric tooth brushing.
Embodiment one, the prior art eccentric hammer pitman shaft A4 close to 2 one end of micro machine diameter be d1, the position d1 distortion
Point is that a long section reduces diameter line, and when distorting rotation, d1 is that the mode of presentation circular arc is bent 360 degree rotation, and d1 is straight
Diameter is done thick, and bending torsion is big, is wasted power of motor, is weakened the power of normal conduction；D1 runs business into particular one, due to being a long sections of straight
Radial line, it is easy to this section of diameter line occur and occur twisting joint (fried dough twist shape).Three sections of 901 energy of bending section of circular arc type of the utility model
Diameter is done it is tiny, be bent rotation when, be that three points do different bending forces, do not influence power of motor, no
Weaken the power of normal conduction；
The eccentric hammer pitman shaft A4 and equal diameter eccentric hammer 5 of the prior art are that direct diameter device to hole is cooperatively connected, and use one
After the section time, the phenomenon that often having skidded, lead to not normal use.The conical eccentric of the utility model hammers anti-skidding detent into shape
903 design, directly and conical eccentric hammer 10 does fitting detent, simple and practical, never skids；
5 diameter of equal diameter eccentric hammer of the prior art is greater than the junction of eccentric hammer pitman shaft A4, when bending rotates
It waits, the amplitude of fluctuation of equal diameter eccentric hammer 5 is in different size.The utility model allows taper by three sections of eccentric hammer stable sections 902
Eccentric hammer 10 does support there are three point always when swinging and carrys out stable oscillation amplitude, puts just as three bearings in bending
Outer ring positioning support is done when moving excessive, so that conical eccentric hammer 10 is done stable rotation, is added at three supporting point clearance grooves
Gluey lubricating oil plays the role of reducing friction；
5 diameter of equal diameter eccentric hammer of the prior art is big, causes 7 diameter of toothbrush handle that can not reduce, if by lengthening brush
First 8 run business into particular one brush bar, then equal diameter eccentric hammer 5 is practical will to be increased with a distance from 8 bristle of brush head, then amplitude of fluctuation will
Reduce, influences toothbrushing effect.The conical eccentric hammer 10 of the utility model using one third equal diameter eccentric hammers plus three/
Two taper eccentric hammer structures, conical eccentric hammers end diameter into shape and 8 bristle orientations of brush head are close, can reduce the diameter of toothbrush handle 7,
Amplitude of fluctuation can be increased, preferably clean tooth, it is not easy to occur toothbrush handle 7 crack a joke, numb tooth the phenomenon that；
The head eccentric hammer swinging axle A6 of the prior art is that zero diopter either four equal part protrusions are strong, causes using
When, since the twisting up and down of eccentric hammer swinging axle A6 and toothbrush handle 7 is skidded, it is easy to appear noise, and be gradually increased, swung
Amplitude can also decline, and influence normal use.The upper surface of eccentric hammer swinging axle B11 of the utility model is provided with toothbrush head rod inner hole
Anti- DNA releaxed circular DNA 12 is also able to achieve proper engagement size when upper and lower twisting, and the appearance of control noise guarantees the steady of amplitude of fluctuation
It is fixed.
In conclusion the utility model provides a kind of electric toothbrush resonance shaft assembly, structurally reasonable, three sections of circular arc type bendings
Section diameter can be done it is tiny, be bent rotation when, be that three points do different bending forces, do not influence motor function
Rate does not weaken the power of normal conduction；Conical eccentric hammers anti-skidding detent into shape directly and conical eccentric hammer does fitting detent, simple real
With never skidding；For three sections of eccentric hammer stable sections when conical eccentric is hammered into shape and swung, three shaft shoulders carry out stable oscillation as support
Amplitude, makes conical eccentric hammer stable rotation into shape, and gluey lubricating oil plays the role of reducing friction；Conical eccentric hammer uses one third
Equal diameter eccentric hammer adds 2/3rds taper eccentric hammer structures, and conical eccentric hammers end diameter into shape and brush head bristle orientations are close,
The diameter of toothbrush handle can be reduced, amplitude of fluctuation can be thus increased, preferably clean tooth, it is not easy to toothbrush handle occur and beat
The phenomenon that tooth, numb tooth；The anti-DNA releaxed circular DNA of toothbrush head rod inner hole is also able to achieve proper engagement size, control noise when upper and lower twisting
Appearance, guarantee the stabilization of amplitude of fluctuation.So the utility model effectively overcomes various shortcoming in the prior art and has height
Spend value of industrial utilization.
The above embodiments are only illustrative of the principle and efficacy of the utility model, and not for limitation, this is practical new
Type.Any person skilled in the art can all carry out above-described embodiment under the spirit and scope without prejudice to the utility model
Modifications and changes.Therefore, such as those of ordinary skill in the art without departing from the revealed essence of the utility model
All equivalent modifications or change completed under mind and technical idea, should be covered by the claim of the utility model.
