US 2022/0258902 A1 · GARBAGE BIN, BIN LID AND AUTOMATIC CUTTING MECHANISM FOR GARBAGE BAG

Abstract

The present disclosure relates to a garbage bin, a bin lid, and an automatic cutting mechanism, wherein the cutting drive device drives the first cutting assembly to move along the first guiding assembly and drives the second cutting assembly to move along the second guiding assembly; the first cutting assembly and the second cutting assembly are approached and moved away from each other when moving back and forth. When approaching to each other, a twisted seal at the upper end of the garbage bag is clamped and cut, and after moving away from each other, a space is left for the new garbage bag at the upper end to expand downwards. The automatic cutting mechanism clamps the twisted seal, a size required to be heated is short, the required heat is little, the heating block and power consumption are low, thus the environmental protection is improved.
