Problems solved by technology

[0005] But this kind of dust removal accessory also has shortcomings: the connection between the lid and the trash can only depends on the cooperation of the drawstring at the bottom of the lid and the flanging of the trash can, and the flanging of the trash can avoids the lid that locks the drawstring It is possible to slip off the edge of the trash can, but for a trash can with a flip cover, the cover of the dust removal accessory cannot cover the flange at the connection between the flip cover and the trash can, resulting in a gap here, causing dust and other garbage to flow from here The gap leaks out. When the blower sucks in a lot of gas and cannot discharge it in time, the lid is easy to break free from the shackles of the drawstring and slip off the edge of the trash can, resulting in a large area of ​​dust being scattered.
