Meanwhile, the opening of the garbage can 20 is shielded by the bed body 12, and the garbage can 20 is further sealed, so that peculiar smell diffusion or germ diffusion pollution and the like are prevented.

Similarly, in the process of changing the trash can 20 from the state of fig. 2 to the state of fig. 3, the strip 24 gradually loosens, and simultaneously, under the elastic action of the elastic rope 26, the annular sleeve 25 is pulled to move towards the inner wall of the trash can 20, so that the circle formed by the strip 24 inside the trash can 20 gradually becomes larger.

The rubber layer is mounted on the inner side of the strip 24, static electricity is generated due to friction between the rubber layer and the garbage bag, and the strip 24 is already rubbed against the garbage bag when the strip 24 is contracted, so that static electricity exists on the inner side of the strip 24, and therefore when the circle formed by the strip 24 is enlarged, the strip 24 pulls the garbage bag to move towards the inner wall of the garbage can 20, so that the garbage bag is re-opened. Even though the bag is less effective to open, the top of the bag is always in a perfectly circular open position and does not prevent the doctor from discarding the waste into the interior of the trash can 20.
