A multi-stage cyclone separation dust collection device and vacuum cleaner

Abstract

The invention discloses a multistage cyclone separation dust collection device which comprises a dust collection cup; a first-stage cyclone channel and a second-stage cyclone channel are arranged in the dust collection cup, the first-stage cyclone channel and the second-stage cyclone channel communicate through a second-stage separation inlet, and the second-stage cyclone channel and a clean air outlet communicate through a second-stage separation outlet; a third-stage cyclone channel is further arranged in the dust collection cup, the first-stage cyclone channel and the third-stage cyclone channel communicate through a third-stage separation inlet, and the third-stage cyclone channel and the second-stage cyclone channel communicate through a third-stage separation outlet; and air in the first-stage cyclone channel is subjected to three times of direction change in the process of entering the second-stage cyclone channel through the three-stage separation inlet, the third-stage cyclonechannel and the third-stage separation outlet. A new separation path is added on the basis of an original separation path; and on one hand, the situation that the separation effect is weakened due toblockage of the original separation path is avoided, and on the other hand, the separation path length in the whole separation process is increased by the new separation path, so that the separationprocess is completer.
