Referring to fig. 1 and fig. 2 again, the intelligent trash can provided by the invention comprises a can body 1 and the trash can opening and closing mechanism, wherein the intelligent trash can comprises a large cover 21 covering the can body 1 and a small cover 22 covering the large cover 21. In an embodiment, the lid 2 included in the opening and closing mechanism of the trash can may be a large lid 21, and the connecting seat 11 is a part of the can body 1; in another embodiment, the cover body 2 included in the opening and closing mechanism of the trash can may be a small cover 22, and the connecting seat 11 is a part of the large cover 21.

As can be seen from the above detailed description of the embodiments, the cover opening and closing mechanism for a trash can provided by the present invention is provided with the support shaft 4 fixedly connected to the cover body 2, and the motor 31 drives the support shaft 4 to rotate through the connecting rod assembly 3 to drive the cover body 2 to rotate, open and close.

Although the present application has been described with reference to a preferred embodiment, it should be understood that various changes, substitutions and alterations can be made herein without departing from the spirit and scope of the application, and all changes, substitutions and alterations that fall within the spirit and scope of the application are to be understood as being covered by the following claims.
