The first accommodation chamber 21 corresponding to the position below the garbage injection port 10 is provided with a garbage can 23 with an open top, and a garbage baffle is provided. The portion 24 is located above the middle of the trash can 23, the lower end of the trash baffle portion 24 is 2 cm to 30 cm from the top of the trash can 23, and the lower vertical plate portion 18 corresponding to the position of the trash can 23 is provided with a trash can replacement port. The top is 2 cm to 15 cm higher than the top of the trash can 23 , a first box door 26 is provided at the replacement port of the trash can, and a second box door 27 is provided on the rear box wall 15 corresponding to the position of the second accommodating room 22 . The inner space of the trash can body is divided into a first accommodating chamber 21 and a second accommodating chamber 22 by a partition plate. Make full use of the space above the rear of the trash can 23 in the trash can body, which greatly improves the space utilization rate. The second accommodating room 22 can be used as a tool room, and some cleaning tools can be placed inside it, such as brooms, dustpans Such tools, thereby increasing the function of the garbage can, when in use, as garbage is continuously thrown from the garbage inlet 10, the garbage will gradually rise above the trash can 23 until the inner cover 2 is lifted by the garbage to remind people of the garbage. The garbage can be filled until the garbage baffle is full, and due to the setting of the garbage baffle 24, the garbage higher than the garbage can 23 is basically blocked on the left side of the garbage baffle 24, and the upper space behind the garbage can 23 located on the right side of the garbage baffle It is not filled with garbage to form the remaining space. According to the demand, when the inner cover plate 2 is lifted up when the garbage in the garbage can overflows, the volume of the garbage higher than the replacement opening of the garbage can is smaller than the volume of the remaining space of the garbage can. When the bucket replacement port pulls the trash can 23 outward, the garbage at the top of the trash can 23 is blocked by the top wall of the trash can replacement port, so that it falls into the remaining space in the upper part of the trash can 23, thereby avoiding the high garbage accumulation. Causes the problem that garbage is scattered everywhere when the trash can 23 is pulled out, which is convenient for the quick removal of garbage. In this embodiment, the lower end of the trash baffle 24 is 5 cm away from the top of the trash can 23, and the top of the trash can replacement port is higher than the trash can 23. 2 cm from the top.

The above technical features constitute the best embodiment of the present invention, which has strong adaptability and best implementation effect, and can increase or decrease unnecessary technical features according to actual needs to meet the needs of different situations.
