21, vacuum cleaner as claimed in claim 20, it is characterized in that, described second chip limits rear surface and first couple of apparent surface by element, it is characterized in that, described first couple of apparent surface's a surface is greater than first couple corresponding apparent surface, and opening limits an acute angle with respect to the rear surface like this.

22, vacuum cleaner as claimed in claim 21 is characterized in that, element is passed through with respect to first chip in described rear surface.

23, a kind of vacuum cleaner is characterized in that, comprising:

Shell with inlet of the chip that is suitable for receiving vacuum absorption;

Be fixedly connected to the mounting rod on the shell;

The floor-type dust collector assembly, be provided with rotationally around the first axle that limits by mounting rod, the floor-type dust collector assembly comprise be connected to mounting rod first chip by element, to link to each other by element with first chip and have what limit opening rotationally be that second chip of rectangular path is by element be detachably attached to three chip of second chip by element and pass through element substantially; And

Wherein the floor-type dust collector assembly can be operated with various modes, comprising:

First pattern, its split shed is basically perpendicular to the vacuum cleaning surface;

Second pattern, wherein second chip rotates around second axis by element with respect to first chip by element, this axis limits by being respectively formed at the flange and the hole of first and second chips by the cooperation on the element, opening is at the acute angle place with respect to the vacuum cleaning surface like this, and second axis is basically perpendicular to first axle; And

Three-mode, wherein the 3rd chip is connected to second chip by element by element, wherein passes the 3rd chip and is basically parallel to the vacuum cleaning surface by the passage that element limits.

24, a kind of vacuum cleaner is characterized in that, comprising:

Shell with inlet of the chip that is suitable for receiving vacuum absorption;

Be arranged on the air inlet on the shell;

Be arranged in the floor scraper bowl on the shell; And

Access door, be connected on the shell and between the primary importance and the second place, move, in primary importance, access door is away from air inlet, the flexible pipe air inlet that is operably connected, thereby air communication flexible pipe are in the second place, access door prevents that air from passing through air inlet, and air replacedly is communicated with the floor scraper bowl.

25, vacuum cleaner as claimed in claim 24 is characterized in that, described access door biasing is to the second place.
