The lithium battery 100 is installed in the handle housing 50 of the handheld floor scrubber, and includes a frame 10, a battery pack 20, a heat sink 30 and a protection circuit 40. A plurality of battery packs 20 are arranged in the frame 10. A wire groove 121 is arranged on the outer wall of the frame 10. The wires electrically connecting the battery pack 20 and the protection circuit 40 are laid in the wire groove 121.

[0025] Specifically, the frame 10 includes a partition 11 and a bridge frame 12. The partition 11 is plate-shaped and has a plurality of positioning grooves on at least one side. The bridge frame 12 is mounted on at least one side of the partition 11. Multiple battery packs 20 are stacked into a battery pack group. The battery pack group is arranged in the positioning grooves and pressed under the bridge frame 12. The battery pack 20 is a soft-pack lithium battery. The battery pack group is fixed together by a heat shrink film.

[0026] Furthermore, the bridge 12 is a frame structure, which is vertically set up on the partition 11. A wire groove 121 is provided on the outer edge of the bridge 12. The wire groove 121 is arranged along the direction of the bridge 12. The wires connecting the battery pack 20 and the protection circuit 40 are laid through the wire groove 121. The outer edge of the bridge 12 is inserted into the slide groove of the inner wall of the handle housing 50, such as Figure 4 As shown, the structure is compact, and the wires electrically connecting the battery pack 20 and the protection circuit 40 , the wires electrically connecting the protection circuit 40 and the cover plate 52 of the handle housing 50 , and the wires electrically connecting the protection circuit 40 and the push switch 51 of the handle housing 50 are all laid through the wire groove 121 .

[0028] See also Figure 3 , Figure 3 A bridge frame 12 structure is shown, and a plurality of notches 122 are provided on the outer edge of the bridge frame 12. The notches 122 are arranged above the electrical connection of the battery pack 20, so that the wires can enter the wire groove 121 without bypassing the horizontally adjacent battery packs 20. The depth of the notches 122 is greater than the depth of the outer edge of the bridge frame 12 inserted into the slide groove in the handle shell 50.

[0029] The handheld floor scrubber has a compact structure, the lithium battery 100 has a large discharge rate and generates severe heat, so heat sinks 30 are provided on both sides of the battery pack 20 .
