Dustproof lithium battery with efficient heat dissipation

The utility model provides an efficient heat dissipation dustproof lithium battery which comprises a heat dissipation assembly, and the heat dissipation assembly comprises a dustproof box, a dustproof cover, a U-shaped plate, a first rotating rod, a first gear, a fan blade, a motor, a lithium battery shell, a rectangular hole, a heat dissipation plate and a heat dissipation copper sheet. The dustproof box is movably in contact with a dustproof cover, a U-shaped plate is welded to the top of the dustproof cover, and a first rotating rod is rotationally installed between the inner walls of the two sides of the U-shaped plate. The motor drives the first gear to rotate through the first rotating rod, the first gear drives the second rotating rod to rotate through the second gear, the second rotating rod drives the fan blades to dissipate heat of the lithium battery shell, heat energy generated by the lithium battery shell is discharged through the heat dissipation plate, and the heat dissipation copper sheets can
