Description

Vacuum cleaner

Technical field

the utility model relates to a kind of vacuum cleaner.

Background technology

On the dustless bag of the known cyclone type dust catcher, the cyclonic filter system has two kinds substantially.First kind of built-in extra screen pack in the cyclone dust bucket as first order filtration system normally filters dust like the HEPA filter.The characteristics of this system are a large amount of first-hand dusts along with air-flow directly rotates around the HEPA filter after getting into the dirt bucket; Because first order cyclonic separation weak effect often, dust can not separatedly effectively go out and be brought under control, and screws off but in the cyclone dust bucket, constantly screw on air-flow; Be easy at last to be seen through the HEPA filter the suction of central suction power and attached on the HEPA filter; And the filtration grade of HEPA filter is very high, and screen pack is easy to stopped up by dust, thereby makes the suction power of dust catcher descend very soon; Cause the user to have to often clean or change filter, influenced the normal use of dust catcher.Therefore, this kind dust catcher is just constantly substituted by second kind of multi-stage spiral-flow-wind dust sucking device.

second kind are usually alleged multi-stage spiral-flow-wind dust sucking devices, and it carries out the multistage cyclone separation through the cyclonic separation unit that plural serial stage is set to dust, thereby makes dust can be stayed up hill and dale in the separative element of dust catcher.DYSON (wearing gloomy/Britain) as the rotoclone collector leader has promptly adopted above-mentioned design at present.Yet find that in actual use perhaps owing to the limitation of domestic vacuum cleaners size dimension and the problem of structural design, first order cyclone filter often can not centrifugalize dust efficiently and control dust effectively.This mainly is because as cyclone filter, its operation principle is exactly to utilize centrifugal principle that heavier-than-air particle is separated from air in the rotation at a high speed.Reach this purpose, two main points are arranged: the one, rotate at a high speed, promptly dust will rotate at a high speed with air-flow, and dust granule increases from the attraction center more and more far away with speed like this.The 2nd, particle is enough far away from the suction force center, and particle just can be fled to such an extent that go out.If just speed is fast, but can not arrive enough far point, that is to say that particle is far away inadequately from the suction force center, it still can only rotate at a high speed with air-flow.Like this, the cyclonic separation dirt bucket of domestic vacuum cleaners, according to centrifugal separating effect, diameter is the bigger the better, and highly also is high more good more.But receive the restriction of dust catcher complete machine size, diameter can not be very big, and diameter is big, and rotary speed can reduce, centrifugal effect meeting variation, so diameter can not be very big, that is merely able to increase the height that vacuum cleaner cyclone separates the dirt bucket.On dust catcher; The aspirating mechanism operated by rotary motion is above dust catcher; The height of cyclonic separation dirt bucket is high more, and just long more below the dirt bucket, separating effect is just good more like this; If there are not enough length spaces to let dust granule arrive the critical point of an escape below, dust just cannot leave the air-flow of rotation.Around the dirt bucket is a barrel wall, and dust cannot be escaped, and near the suction center, is the air-flow that rotates at a high speed, and dust cannot separate.Dust-contained airflow must be to going down, and must be to rotate downwards at a high speed, and the particle of Different Weight could escape from swirling eddy in the critical point different from the suction force center.

so, reason is recognized to go up and said that whirlwind speed is big more, and is long more below the dirt bucket, dust granule separate with regard to more totally, thorough more.And actual situation is, the speed that the dust catcher air-flow gets into is very big, and dirt bucket lower length cannot be very long, the air-flow that rotates at a high speed abrim in the dirt bucket, and the air-flow of rotation can drive the dust that becomes quiet at any time once more at a high speed, and promptly dust cannot stop.Particularly light, book; Often constantly rotate such as the modal dust of present family such as the scraps of paper, fibre fluff, hair with air-flow; On the screen pack attached to the setting of next stage cyclone filter front, cause dust catcher suction to descend at last, or get into the next stage filtration system; Thereby increase the weight of the burden of next stage filtration system, also therefore cause this multistage cyclone system effectively and efficiently dust as much as possible not to be filtered out.For example publication number is the Chinese patent " multi cyclone dust-separating apparatus of vacuum cleaner " of CN101292851; Wherein disclosed just as above-mentioned mention can not effectively carry out dust separating dust catcher; After falling into the bottom of this grade cyclone separator through first order cyclone separator separated dust, having the sub-fraction dust can not block owing to having, and along with ascending air is carried secretly to the mesh filter place; This not only can cause the separative efficiency of first order cyclone separator to lower; And because the grit of the dust of being carried secretly is generally bigger, and the mesh of mesh filter can be blocked, thus whole dust catcher cisco unity malfunction made.Other is also to be to have as above problem in the rotoclone collector described in CN1422187A, the CN100998484A like publication number.
