Problems solved by technology

This kind of 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

Abstract

The invention discloses a cyclone separator. The cyclone separator comprises a first separation cavity, a second separation cavity, an air outlet and a dust discharge opening. The first separation cavity comprises a bottom surface in the reversely-conical structure and multiple air-guide blades in arc structures. The multiple air-guide blades are uniformly and spirally arranged onto the bottom surface in order to form multiple air channels. An air channel inlet is formed by an outer end of one air-guide blade and an outer end of an adjacent air-guide blade. An air channel outlet is formed by an inner end of one air-guide blade and an inner end of an adjacent air-guide blade. The first separation chamber communicates with the bottom end of the first separation cavity. The bottom surface ofthe second separation cavity is a spirally-downward channel which is coaxial to the bottom surface of the first separation cavity. The air outlet is arranged at the top end of the first separation cavity. The dust discharge opening is arranged at the tail end of a channel of the second separation cavity. The invention also discloses a filtering assembly. The cyclone separator is equipped with twoseparation cavities which can perform cyclone separation twice on dust-laden gas. Therefore, better filtering effect is obtained.

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. The separation chamber of the existing cyclone separation unit is usually a single cylindrical or conical shape, and the filtering effect is not ideal. In addition, 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 gu...
