Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of trash cans, in particular to a trash can. Background Art
[0002] A trash can, also known as a waste bin or garbage bin, refers to a place for storing garbage. Most of them are made of metal or plastic. Plastic bags are put in them when used. When there is a lot of garbage, the bags can be tied up and thrown away. Most trash cans have lids to prevent the odor of garbage from spreading. Some trash cans can be opened with a foot pedal. Most household trash cans are placed in the kitchen to store kitchen waste. Some families place one in each main room. No matter what kind of garbage it is, it will produce a lot of odor after being placed for a long time. Even using trash bags cannot completely cover it, especially when the trash bag is punctured and ruptured, causing the liquid inside to flow out, which will further prolong the retention time of the odor.
[0003] The Chinese utility model patent with publication number CN217200021 U discloses an anti-odor trash can, which blocks the odor in the trash can body through a blocking seat so that it will not be released, effectively preventing the odor in the trash can body from being released to the outside and causing great environmental pollution, and also greatly avoiding the harm of the odor to the human body, which meets the existing requirements for the use of trash cans. However, the device still has some other problems. For example, the trash can only prevents the odor from being released to the outside by adding a baffle to block the garbage inside. However, when the trash can is opened, the structure will still cause the odor to be released in a short time in the open state. When an adsorbent such as activated carbon is used to adsorb the odor, the activated carbon is exposed to the outside for a long time, resulting in a short service life and frequent replacement.
