[0002] Trash cans are an indispensable necessity in human life, and we can see them almost every day. They are indispensable in today's home furnishings, hotel supplies market, and even in the streets and alleys. With the general improvement of people's environmental awareness and aesthetic level, the types and number of trash cans are constantly being renovated and increased. People pay more attention to its practicality, and product functions are also developing in the direction of "practicality" and "intelligence".

[0003] In the patent document with Chinese patent application number 201922417830.5 and publication date 2020.09.11, an automatic bagging device for trash cans is disclosed, comprising a waterproof base, a bag outlet groove is provided on the top outer wall of the waterproof base, a storage box is provided on one inner wall of the waterproof base, a plug-in rod is provided on one inner wall of the storage box, and a trash bag is sleeved on the outer wall of the plug-in rod, hot rollers are connected to both sides of the central axis of the inner wall of the waterproof base through shafts, and the trash bag is rolled and connected to the inner wall of the opposite side of the two hot rollers, and a barrel body is integrally connected to the top outer edge of the waterproof base. The utility model is integrated on the trash can, and the sticking roller on its piston rod is driven by a micro motor and a hydraulic strut to open the trash bag into a bucket-shaped structure. After the bag body is taken out by the light sensor, the micro motor and the hydraulic strut are driven to automatically clamp the end of the trash bag at the bottom, and the end is glued to the outer wall of the driving sticking roller after being glued by the glue roller and preheated by the hot roller to open, and the bag is automatically changed, which is convenient and quick.

[0004] However, after the garbage bag is opened by the hydraulic support rod, the bag is in a bucket-shaped structure. In this state, the space at the bottom of the garbage bag is not opened. Therefore, when garbage is thrown in, heavier garbage directly hits the garbage bag. If the sticky roller does not stick to the garbage bag firmly, the garbage may drive the top of the garbage bag to separate from the sticky roller, thereby causing the garbage bag to fall off and other problems. Summary of the invention
