As society continues to advance, environmental health has received increasing attention. In real life, garbage sorting and recycling has become popular, and devices such as trash cans that store garbage are widely used.

The trash can in the prior art mainly has the following defects:

1. The existing flip cover is in the form of a single flip cover. The main disadvantage is that if the flip cover is turned inward (mostly), the running space of the flip cover must not be obstructed by garbage (otherwise the flip movement will be blocked), so a single flip will result in a larger The amount of trash can is lost. If it is to be ensured that there is sufficient effective volume, it is necessary to design the height of the trash can to be higher, which in turn affects the smoothness of the placement, is more easily dumped by lateral forces (human or wind, etc.), and personnel delivery Garbage is inconvenient. In addition, the rotating shaft of the flip cover is generally disposed in the middle of the barrel mouth, and the rotating shaft separates the trash can into two spaces, which affects the opening degree of the trash can, and the large garbage is inconveniently poured.

2. The smell emitted by the trash can is very disgusting to the pedestrians and surrounding residents. The existing outdoor trash can mainly considers the function of the container and considers less in preventing the odor from flowing.

3, the problem of rain, outdoor trash can inevitably encounter rain and snow weather, water into the trash can cause many problems, such as: if the rain into the trash can, will cause sewage, affecting the future dumping of garbage, causing secondary pollution, At the same time, the rain also takes up the volume of the trash can and causes the problem of waste fermentation and odor.
