Therefore, the garbage delivery opening 3 can be opened flexibly in multiple directions, making it convenient for users to deliver garbage at multiple different angles.

[0046] When the trash can is full and needs to be dumped or the medical waste bags need to be taken out, the lid opening pedal 6 can be pressed to drive the lid flip driving rod 23 of the lid opening transmission mechanism to move, and the vertically arranged lid flip transmission rod 26 can be used to drive the flip lid 2 to flip upward around the barrel hinge 41 and open; then, after the garbage is taken out, the lid opening pedal 6 is released, and the flip lid 2 returns to the initial closed state by its own gravity.
