To the garbage bin of new production, both can adopt the fastener mode installation fixed, also can adopt buckle structure installation fixed, because the broken bag device's of gravity auto-lock pure mechanical structure, the stable performance, when production, also can adopt the base with the casing and garbage bin integrated into one piece, also can bond or weld the broken bag device of gravity auto-lock in the garbage bin. In this embodiment, preferably, the gravity self-locking bag breaking device and the trash can 5 are installed and fixed through a fastener, which is suitable for installation of each community under the present circumstances.
The garbage can has good practicability, can meet the requirement of the transformation of the existing community garbage can, and better implements garbage classification.
The above-described embodiments are merely preferred embodiments of the present invention, and should not be construed as limiting the present invention, and features in the embodiments and examples in the present application may be arbitrarily combined with each other without conflict. The protection scope of the present invention is defined by the claims, and includes equivalents of technical features of the claims. I.e., equivalent alterations and modifications within the scope hereof, are also intended to be within the scope of the invention.
