Double-layer garbage can

The invention belongs to the technical field of garbage cans, and particularly relates to a double-layer garbage can. The double-layer garbage can comprises an inner barrel, which is provided with a feeding port; an outer barrel, which is arranged on the outer side of the inner barrel and is rotationally provided with a handle; a limiting part, which is arranged on the inner barrel; and a locking assembly, which is mounted between the outer barrel and the inner barrel and is in linkage with the handle. The locking assembly comprises a first component and a second component, wherein the first component is connected with the handle and rotates along with the handle, and the second component is driven by the first component to rotate intermittently in one direction to be locked to and unlocked from the limiting part. According to the double-layer garbage can, the handle can be reset after rotating once to realize locking or separating of the inner barrel and the outer barrel, at the moment, due to the fact that
