Abstract

A silence multifunctional trash bin supplying bags in bulk and automatically opening the bags, comprising an upper housing (10), a bin body (14), and a bottom housing (29). The upper housing (10) comprises a bag-clamping and bag-opening apparatus and a lid-opening/closing apparatus. The bottom housing (29) comprises a trash bag length positioning apparatus, a silencing and cushioning apparatus, an opened lid locking apparatus, a bag-opening resetting apparatus, and a trash bag storage cavity. A trash bag being drawn out triggers the trash bag length positioning apparatus and the bag-clamping and bag-opening apparatus into action, thus implementing automatic bag clamping and trash bag tear off functions. Furthermore, when a pedal (26) is stepped down, flipping lids (8 and 9) are opened, the pedal (26) pulls a resetting pull hook (28) and drives a bag-clamping pull rod (34), the bag-clamping pull rod (34) drives plastic strips (3 and 4) on U-shaped clamping rods (1 and 6) to open the opening of the trash bag, when the pedal (26) is released, a damping disk having a viscous liquid obstruct the return of the pedal (26), and the flipping lids (8 and 9) close slowly. The trash bin consecutively supplies trash bags, automatically changes a new trash bag when trash is being taken out, and automatically opens the bag opening, and triggers by means of an action of either foot an opened lid locking button (25) to lock the bin lids into being normally opened.
