Dust separator and vacuum cleaner

Abstract

The invention provides a dust separator, comprising a dust barrel, a cover plate that covers the dust barrel to jointly form a receiving space, a dust inlet running through the dust barrel, a dust incoming passage formed in the receiving space and communicated with the dust inlet, an exhaust hole running through the cover plate, and primary and secondary separation units mounted in the receiving space. The primary separation unit has horizontally arranged axis, and the secondary separation unit has vertically arranged axis; the secondary separation unit is arranged downstream of the primary separation unit along the flow direction and is serially connected with the primary separation unit. The invention also provides a vacuum cleaner. Compared with the prior art, the dust separator and thevacuum cleaner have high dust suction capacity, long service lives and low cleaning frequency.

Description

technical field [0001] The invention relates to the field of sanitary tools, in particular to a dust separating device and a vacuum cleaner. Background technique [0002] The existing horizontal vacuum cleaners and portable dual-purpose stick vacuum cleaners on the market are basically in the form of one-stage separation as long as the dust separation device using the cyclone cone to separate dust is used. , paper shreds, beans, etc.) have a good separation effect. But for hair, ribbons, flour and other dust, the separation effect is relatively poor, especially when the ribbon is wrapped around the cyclone cone, the ability to separate dust as fine as flour will be lost, and it can only be intercepted and filtered by filter cloth or Hypa , This will easily cause the filter cloth or Hypa to be clogged, resulting in the rapid loss of the product's dust-absorbing ability. At this time, it is necessary to clean the cyclone cone and clean the filter cloth or Hypa immediately, ot...

AI Technical Summary

Problems solved by technology

But for hair, ribbons, flour and other dust, the separation effect is relatively poor, especially when the ribbon is wrapped around the cyclone cone, the ability to separate dust as fine as flour will be lost, and it can only be intercepted and filtered by filter cloth or Hypa , it is easy to cause blockage of the filter cloth or Hypa, resulting in the rapid loss of the product's dust-absorbing ability. At this time, it is necessary to clean the cyclone cone and clean the filter cloth or Hypa immediately, otherwise the motor will not be able to dissipate heat and burn down

[0003] In addition, the dust separation device of some existing horizontal vacuum cleaners and portable dual-purpose stick vacuum cleaners directly uses filter cloth or Hypa to directly intercept and filter the dust. It is easier to drop sharply, causing the product to be unable to vacuum or seriously causing the motor to be unable to dissipate heat and burn out

[0004] Moreover, the vacuum cleaner using the above-mentioned dust separation device in the related art needs to frequently clean the cyclone cone or clean the filter cloth or hypa, which causes inconvenience to the user, and at the same time, it is easy to cause the motor to be unable to dissipate heat and burn out.
