2009年出现了新一代的垃圾桶，它们体积不大，却可比传统垃圾箱多装8倍垃圾量的高科技垃圾箱。这种俗称“大胃王”的垃圾箱，外表像个邮筒。一般垃圾箱可以处理约181.6升的废弃物，但“大胃王”可以一次存放1362升的垃圾。换句话说，清洁人员原本每天收集一次垃圾，如今只要每周收集一次。这些垃圾桶利用太阳光作为动力能源，经过自动压缩处理后，可以将垃圾的体积缩小到原来的1/8，因而能“吃”下1362升的垃圾。“大胃王”垃圾箱的另一个特点是全封闭、双门结构，阻止气味溢出，美观又安全，就连老鼠等小动物也不能进入。顶部的绿、黄、红灯，分别代表可以装、装满一半、装满，让使用者一目了然。
In 2009, a new generation of garbage cans emerged. They are small, but can hold eight times more garbage than traditional ones. This dustbin, commonly known as "King of Big Stomach", looks like a mailbox. Ordinary bins can handle about 181.6 litres of waste, but Big Stomach King can store 1362 dingzhou.37ix.com.cntangshan.37ix.com.cnchengde.37ix.com.cnlangfang.37ix.com.cnlitres of waste at xingtai.37ix.com.cnhengshui.37ix.com.cna time. In other words, cleaners used to collect garbage once a day, but now they only collect it once a week. These bins use sunlight as a power source. After automatic compression, the volume of garbage can be reduced to 1/8 of the original, so they can "eat" 1362 litres of garbage. Another feature of the "Big Stomach King" dustbin is its completely closed, double-door structure, which prevents odor overflow, is beautiful and safe, and even small animals such as rats can not enter. The green, yellow and red lights at the top represent that they can be filled, half filled and full respectively, so that users can see clearly.
