Abstract

A shaker includes a base, a holder and a drive assembly. The holder is movably disposed on the base. The drive assembly includes a first eccentric shaft, a second eccentric shaft, a drive shaft, plural magnetic members and a power source. The first eccentric shaft includes a first part and a second part which are non-coaxial. The first part is pivoted on the holder. The second eccentric shaft includes a third part and a fourth part which are non-coaxial. The third part is pivoted on the holder. Two ends of the drive shaft respectively correspond to the second and the fourth parts. The magnetic members are respectively disposed on the second, the fourth parts and the two ends of the drive shaft. The power source is used for rotating the first eccentric shaft, and rotating the second eccentric shaft through the magnetic members and the drive shaft.

First claim

What is claimed is:

1. A shaker, comprising:
a base;
a holder movably disposed on the base; and
a drive assembly, comprising:
a first eccentric shaft, comprising a first part and a second part which are non-coaxial, and the first part pivoted on the holder;
a second eccentric shaft, comprising a third part and a fourth part which are non-coaxial, and the third part pivoted on the holder;
a drive shaft, two opposite ends of the drive shaft respectively corresponding to the second part and the fourth part;
a plurality of magnetic members respectively disposed on the second part, the fourth part and two opposite ends of the drive shaft; and
a power source used for rotating the first eccentric shaft, and rotating the second eccentric shaft through the magnetic members and the drive shaft,
wherein a rotational axis of each of the magnetic members disposed on the drive shaft is orthogonal to both a rotational axis of the magnetic member disposed on the second part of the first eccentric shaft and a rotational axis of the magnetic member disposed on the fourth part of the second eccentric shaft.

2. The shaker according to claim 1 , further comprising two jigs, the first part of the first eccentric shaft having a first slot, the third part of the second eccentric shaft having a second slot, the two jigs slidably disposed on the base and respectively corresponding to the first slot and the second slot.

3. The shaker according to claim 1 , further comprising a position board and a position sensor, the second eccentric shaft disposed through the position board, the position board having a crack, the position sensor near the position board, and a sensing area of the position sensor located on a motion path of the crack.

4. The shaker according to claim 1 , wherein the first eccentric shaft and the second eccentric shaft are rotated jointly.

5. The shaker according to claim 1 , further comprising a handle pivoted on the holder.

6. The shaker according to claim 1 , wherein the power source is a motor.

7. The shaker according to claim 1 , wherein the base comprises a top plate and a plurality of supporting members, the plurality of supporting members protrude from a side of the top plate away from the holder, and the holder and the magnetic members are respectively located on two opposite sides of the top plate.

8. The shaker according to claim 7 , wherein the base further comprises a bottom plate, the supporting members are connected between the bottom plate and the top plate, and the bottom plate is located between the magnetic members and the top plate.

9. The shaker according to claim 8 , wherein the power source is located between the bottom plate and the top plate.
