Multi-stage whirlwind separating device of vacuum cleaner

Abstract

The invention discloses a multi-staged cyclone separating device, which consists of one-grade upstream cyclone separator and two-grade downstream cyclone separator, wherein the inlet hole is set on the one-grade cyclone separator; the bottom of one-grade cyclone separator is one-grade dust-collecting chamber; the bottom of two-grade cyclone separator is two-grade dust-collecting chamber; the hole of one-grade and two-grade dust-collecting chambers possess bottom lids of one-grade and two-grade dust barrel; when the dust is collecting, the dust barrel bottom lid closes and vice versa; the bottom lids of one-grade and two-grade barrels are opened individually to pour ash, which opens lids of one-grade dust bottom and two-grade dust bottom sequently.

Description

technical field [0001] The invention relates to a multistage cyclone separation device of a vacuum cleaner. Background technique [0002] In the prior art, the multi-stage cyclone separation device of the vacuum cleaner at least includes a primary cyclone separator located upstream and a secondary cyclone separator located downstream of the primary cyclone separator. The primary cyclone separator includes an inner bottom with a primary collector. The primary separation bucket of the dust chamber, the secondary cyclone separator includes a secondary separation bucket with a secondary dust collection chamber at the inner bottom; the U.S. Patent No. US6344064 discloses that the separation bucket is disassembled from the dust bucket, and then the The separation barrel is turned upside down so that the dust is poured out from the upper part. Although this method can simultaneously empty the dust in the primary dust collection chamber and the secondary dust collection chamber, in ...

[0002] In the prior art, the multi-stage cyclone separation device of the vacuum cleaner at least includes a primary cyclone separator located upstream and a secondary cyclone separator located downstream of the primary cyclone separator. The primary cyclone separator includes an inner bottom with a primary collector. The primary separation bucket of the dust chamber, the secondary cyclone separator includes a secondary separation bucket with a secondary dust collection chamber at the inner bottom; the U.S. Patent No. US6344064 discloses that the separation bucket is disassembled from the dust bucket, and then the The separation barrel is turned upside down so that the dust is poured out from the upper part. Although this method can simultaneously empty the dust in the primary dust collection chamber and the secondary dust collection chamber, in the multi-stage cyclone separation device, since most of the dust is separated by the primary cyclone Or the filter stays in the primary dust collection room, only a very small part of the dust will stay in the secondary dust collection room, so it is not necessary to empty the secondary dust collection room every time the primary dust collection room is emptied
