It is integrated with the first Magnetic drive wheel on hammer, further includes a connecting shaft, one end of the connecting shaft is provided with the first magnetic described in face and passes
The other end of second Magnetic drive wheel of driving wheel, the shaft is provided with third Magnetic drive wheel, is provided with motor in the handle, institute
It states and is provided with the 4th Magnetic drive wheel on the output shaft of motor, the 4th Magnetic drive wheel described in the third Magnetic drive wheel interval is arranged.
In above-mentioned technical proposal, the drive link includes cavity, and motor, the motor are fixedly installed in the cavity
Output shaft on be connected with pendulum.
In above-mentioned technical proposal, it is arranged at intervals with first seal and second seal below the drive link, institute
State the top that first seal is located at the second seal.
The present invention has the advantages that：The present invention, which effectively avoids, twists the excessive of toothbrush head on drive link
It is dynamic, and at the same time ensure that the normal operation of toothbrush.
Description of the drawings
Fig. 1 is the overall structure diagram of the present invention.
Fig. 2 is along the sectional view at A-A in Fig. 1.
Fig. 3 is the structural schematic diagram of embodiment 2.
Specific implementation mode
Present invention is further described in detail with specific implementation mode below in conjunction with the accompanying drawings：Embodiment 1:Extremely referring to Fig. 1
Fig. 2, a kind of electric toothbrush, including handle 1, one end of the handle 1 is provided with opening, the open end is provided with drive link
2, the drive link 2 includes cavity 20, and one end of the cavity 20 is fixedly installed shaft 3, and setting is rotated in the shaft 3
There is pendulum 4, the first Magnetic drive wheel 5 is integrated on the pendulum 4, further includes a connecting shaft 6, one end setting of the connecting shaft 6
There are the second Magnetic drive wheel 60 of the first Magnetic drive wheel 5 described in face, the other end of the connecting shaft 6 to be provided with third Magnetic drive wheel
61, motor 7 is provided in the handle 1, and the 4th Magnetic drive wheel 70 is provided on the output shaft of the motor 7, it is described
Third Magnetic drive wheel 61 is spaced and the 4th Magnetic drive wheel 70 setting.By between the first, second, third, fourth driving wheel 7
Magnetic drive cooperation the rotation of pendulum 4 and then formed finally so that the 4th Magnetic drive wheel 70 drives the pendulum 4 to rotate
The vibration of drive link 2.
Further, fulcrum bearing (attached drawing is not shown), the connecting shaft 6 are inserted in the cavity 20 of the drive link 2
By the fulcrum bearing rotating support.The open end of the handle 1 is provided with a circle annular wall 10, in one end of the drive link 2
It is provided with block 21, notch 10a is offered in the annular wall 10, the block 21 is located in the notch 10a, and and institute
State notch 10a clearance fits.In above structure, in artificially twisting drive link, due to the cooperation of block 21 and notch 10a, make
Wide-angle will not be twisted by obtaining drive link；Further, since block 21 and notch 10a are gap-matched, therefore it ensure that biography
Lever can generate normal vibration, and be unlikely to transmit excessive vibration at handle.
It is arranged at intervals with first seal 8 and second seal 9, the first seal 8 positioned at 2 lower end of the drive link
Positioned at the top of the second seal 9, between 1 inside of the first seal 8 and the second seal 9 and the handle
Interference fit, more specifically, is interference fitted between the inside for the annular wall 10 being arranged on handle 1.Wherein described first is close
Sealing 8 uses O-ring, the second seal 9 that gas-flow closure circle, the gas-flow closure circle is used to have and can be connect with the external world
Air inflation nozzle (attached drawing is not shown).In above structure, all by the first seal 8 by the stable transmission on the handle,
The deflection angle of the drive link 2 is controlled by controlling the gas flow in the second seal 9, this makes electric toothbrush
Motor output frequency can readily be adjusted to it is consistent with the intrinsic frequency of total.
Embodiment 2:Referring to Fig. 3, including handle 1, one end of the handle 1 is provided with opening, is arranged in the open end
