Go out and smaller left-right rotation frequency, and left-right rotation angle can also be reduced, reduce the occupancy to space in rotation process.
The axostylus axostyle 11 inserts first hole 6 from the lower section of the drive block 3, and the power transmission shaft 8 is from the drive block 3
Top insert second hole 7 so that the drive block 3 is located between eccentric shaft 2 and contiguous block 4, drive block 3 will not be from axle
Depart from bar 11 or power transmission shaft 8, keep the reliable transmission of transmission mechanism.
The first end of the contiguous block 4 is provided with mounting hole 9, and the mounting hole 9 is placed on the main shaft 5 and the peace
Relatively unrotatable between dress hole 9 and the main shaft 5, main shaft 5 and contiguous block 4 take separate type fit structure, convenient production system
Make and ensure the stability of attachment structure.According to above scheme, pass through interference fit between the mounting hole 9 and the main shaft 5
Connection is installed.It is a kind of selection using interference fit, fit structure is simple, transmission effect reaches use requirement.Or, the peace
One in hole 9 and main shaft 5 is filled provided with counterpart is stretched out, another is provided with retraction counterpart, when mounting hole 9 is placed on institute
The stretching counterpart and retraction counterpart coordinate to prevent the mounting hole 9 and main shaft 5 from relatively rotating when stating on main shaft 5.Adopt
With fit key between this such as axis hole or non-circular etc fit structure, equally have fit structure simple, be driven effect
Reach the advantage of use requirement.
As shown in Fig. 2 also including the support being fixed on motor 1, the support is provided with axis hole, and the main shaft 5 can turn
It is located at dynamicly in axis hole, main shaft 5 is limited with motor 1, makes the motion of the left-right rotation under the driving of motor 1 of main shaft 5 more
It is stable, keep efficiently output.The support includes underframe 12 and restocking 13, and the underframe 12 is fixed on the end face of the motor 1,
The restocking 13 is fixedly installed on underframe 12 by screw, and the axis hole is through restocking 13 and extends on underframe 12, is led to
The cooperation of underframe 12 and restocking 13 is crossed, production and assembling are more convenient on the premise of performance requirement is met.
The utility model also provides a kind of electric toothbrush, as shown in figure 4, including fuselage 14 and brush 15, the fuselage 14
Interior to be provided with low-angle left-right rotation device as described above, the brush 15 is fixedly connected on the main shaft 5；The fuselage 14
Inside it is additionally provided with and rechargeable battery 16 and control panel 17, the control panel 17 is electrically connected between the battery 16 and motor 1.This
The electric toothbrush of utility model can drive bristle low-angle left-right rotation, and big with driving torque, bristle is accounted in rotation process
It is small with space, while also having the advantages that vibrating effect.
It when using electric toothbrush of the present utility model, can be operated, be come by the switch key on control panel 17
The rotating speed and torque output size of motor 1 are controlled, rechargeable battery 16 is powered by control panel 17 to motor 1, after motor 1 is operated
Axle bed 10 is driven to rotate together, the axostylus axostyle 11 on axle bed 10 follows axle bed 10 to rotate together, and axostylus axostyle 11 is on axle bed 10
Eccentric position is rotated around the pivot of axle bed 10.Axostylus axostyle 11 is in eccentric rotary, and axostylus axostyle 11 is in the first hole 6 of drive block 3
Relatively rotate, while pulling drive block 3 to follow axostylus axostyle 11 to move together, drive block 3 is pulled during axostylus axostyle 11 is rotated
Shuttle movement is done, similarly the second hole 7 of drive block 3 is rotatably engaged with power transmission shaft 8, does reciprocating in drive block 3
When mobile, power transmission shaft 8 is also driven to do reciprocating type mobile, so under the drive of power transmission shaft 8, it is past that contiguous block 4 will form left and right
Compound Small-angle Rotation, and then contiguous block 4 drives main shaft 5 to carry out the shuttle Small-angle Rotation in left and right.It is fixed on main shaft 5
Brush 15 just equally carry out the shuttle Small-angle Rotation in left and right, realize this low-angle left-right rotation of brush 15,
During bristle and teeth contact on brush 15, bristle will form the effect vertically brushed teeth to tooth.Small angle of the present utility model
Left-right rotation device and electric toothbrush are spent, 1360 degree of rotations of motor are converted into the output of low-angle left-right rotation, pass through this side
Formula drives brush 15 to carry out low-angle left-right rotation, can provide larger output torque, it is to avoid motor is stuck, both meet science
Vertical teeth brushing way, and left-right rotation angle is small, occupies little space, and may adapt to the tooth of optional position in oral cavity,
As long as the position that toothbrush can be touched can have preferable cleaning effect, simultaneously because the angle of left-right rotation is smaller,
The effect of vibrations can be equal to, further cleaning effect of the lifting toothbrush to tooth.
The above is only better embodiment of the present utility model, therefore all according to described in the utility model patent claim
The equivalent change or modification done of construction, feature and principle, be included in the utility model patent claim.
