Description

The cyclone dust collecting unit of vacuum cleaner
Technical field
The utility model is a kind of cyclone dust collecting unit, particularly a kind of cyclone dust collecting unit of vacuum cleaner.
Background technology
In the vacuum cleaner of the prior art, in order effectively dust to be separated from air-flow, the selection of dust collect plant becomes extremely important, and the dirt bucket begins to use more and more widely, various forms of cyclone separators occurred.For example, patent CN01144402.9 discloses a kind of dust collector barrel of vacuum cleaner, comprising case spare portion, inlet, filter composition. main feature is to be provided with in the upper end of chest portion to carry out open-close lid, filter be arranged on enter the bottom of lid, at a side setting of described case spare portion and the inlet of filter maintenance spacing.By implementing the present invention, because can direct contacted filter, have prevented that filter is subjected to the obstruction of relatively large foreign matter from the inlet leaked-in air.Therefore, can not reduce the suction efficiency of filter, improve rotation gradation dust catching efficiency fully at box house.Simultaneously, because leaked-in air forms spiral flow in the bottom of filter, the size that can regulate above-mentioned filter has fully improved the efficient of filter for filtering fine dust etc.
Though said structure can be realized dust separation to a certain degree, the dust that settles down is driven and enters once more in the ascending air by air-flow easily, causes the dust content in the ascending air big thus, and filter needs often to clean.
Chinese patent CN1309945, a kind of Cyclonic vacuum duster is disclosed, by first end wall, the second opposed end wall, intermediate member is formed cyclone separator, described intermediate member is cylindrical or the band portion truncated cone shape, be provided with tangential air suction inlet near described first end wall, the air outlet slit of tubulose stretches in the described intermediate member and with vacuum source from described first end wall and is connected, it is characterized in that: described second end wall is provided with the dust separation exit passageway, described dust separation exit passageway makes that the outlet of described dust separation exit passageway is arranged in dust storage chamber through this isolated dust haply and be angle less than 90 degree between the eddy axis.Though this patent of invention also is to adopt the mode of whirlwind dust suction to carry out control of dust, no matter be that cinder or thin ash are all unified to collect, tiny dust can't further filter again, motor and thin ash are contacted, cause bad consequence, also have tiny dust in the gas that discharges, influence the quality of air.

As preferably, described one-level cyclonic chamber is provided with entrance cavity, and entrance cavity is tapered, and what be connected with entrance cavity is the one-level disengagement chamber, and the bottom of one-level disengagement chamber is provided with one-level dust fall mouth, and one-level dust fall mouth is connected with the cinder chamber; Described secondary cyclonic chamber was connected with the one-level cyclonic chamber by communicating pipe, be positioned at the interposition of one-level cyclonic chamber communicating pipe, the centre of secondary cyclonic chamber is provided with the air-out connecting leg, the bottom of secondary cyclonic chamber is an outlet plenum, the outlet plenum taper, the secondary disengagement chamber that is connected with outlet plenum, the bottom of outlet plenum are secondary dust fall mouth, and secondary dust fall mouth is connected with thin grey chamber.
As preferably, described dust-collecting cavity and rotary body clamping mutually.
As preferably, described one-level disengagement chamber is horizontal positioned, and described secondary disengagement chamber is vertical placement, and one-level disengagement chamber and secondary disengagement chamber are by perpendicular establishing of communicating pipe.
Therefore, the utility model provides a kind of cyclone dust collecting unit of vacuum cleaner, and is simple in structure, and the whirlwind dust collecting effect is obvious, protection motor service life, reduces the pollution to air.
