Cyclone separator and filtering assembly

Abstract

The invention discloses a cyclone separator. The cyclone separator is arranged on a filtering air duct of a vacuum cleaner. The cyclone separator comprises a separation cavity, multiple air guide blades, an air outlet and a dust discharge opening, and the separation cavity is of an inverse conical structure and is longitudinal; the air guide blades are of the same longitudinal arc face structure and uniformly and spirally surround the top of the separation cavity to form multiple air inlet channels, the bottoms of the air guide blades extend inwards to form air duct base plates, each air guideblade is provided with an outer end and an inner end, the outer ends of the air guide blades and the outer walls of adjacent air guide blades form air duct inlets, and the inner ends of the air guideblades and the adjacent air guide blades form air inlets of the separation cavity; the air outlet is formed in the top of the separation cavity; the dust discharge opening is formed in the bottom ofthe separation cavity. The invention further discloses a filtering assembly. By means of the cyclone separator, multiple air inlet channels are formed through the spiral air guide blades, the air guide effect is improved, inlet air is uniform, and thus the separation efficiency is improved.

Description

technical field [0001] The invention relates to the field of vacuum cleaners, in particular to a cyclone separator and a filter assembly. Background technique [0002] In order to achieve a good filtering effect, the filter assembly of the existing vacuum cleaner usually has a multi-stage filtering function, wherein one-stage or two-stage filtration adopts a cyclone separation unit. In order for the dust-laden gas to generate spiral motion in the cyclone separation unit, its air inlet is usually arranged tangentially. In this way, the dust-laden gas enters the interior of the cyclone separation unit along the tangential direction, and spirals along the inner wall to separate the dust. However, in the above-mentioned cyclone separation unit, the dust-laden gas must gradually generate a spiral motion under the guidance of the inner wall of the cyclone separation unit, so the newly entered dust-laden gas is likely to collide with the airflow that has already produced a spiral ...

AI Technical Summary

Problems solved by technology

In this patent, the cyclone separator has only one air inlet, so the dusty gas cannot enter the cyclone separator evenly, and the spiral movement of the gas in the cyclone separator is also uneven, which affects the separation effect

In addition, the volume of the air guide pipe is large, on the one hand, the structure of the cyclone separator is not compact, and on the other hand, the ideal air guide effect cannot be achieved
