Abstract

The invention provides a vacuum cleaner which can not only prevent the dust collecting bag from being started by mistake, but also make the dust collecting bag easy to assemble and disassemble. A dust collecting bag (9) with a sack coaming plate (8) and a machine cover (6) covering the top of the dust collecting chamber in a rotatable manner. The dust bag detection body (12) is provided on the machine cover, and the dust collection bag detection body is provided with: a raised part (12A) to prevent the machine cover from entering the closed state when the dust collection bag is not installed in the dust collection chamber, and A detection part (12B) for detecting that the dust bag has been loaded into the dust chamber. When the detecting part detects that the dust collecting bag has been loaded into the dust collecting chamber, the protruding part is displaced to a position where the machine cover enters a closed state. In this way, not only can prevent the machine cover from being closed by mistake when the dust bag is not installed, but also, the assembly and disassembly of the dust bag can be carried out by only one action, and the assembly and disassembly will become easy.
