Dust cup of dust collector and dust collector

Abstract

The invention discloses a dust cup of a dust collector, and the dust cup is provided with an air inlet, a primary dust collection chamber, a secondary dust collection chamber, a primary cyclone separator, a secondary cyclone separator and an air outlet, wherein the secondary dust collection chamber surrounds the primary dust collection chamber; the primary cyclone separator is provided with a primary cyclone channel; the primary cyclone channel comprises a surrounding wall and a baffle; the baffle is spirally extended to the bottom, used for receiving crush as, of the primary dust collection chamber from the bottom of the cyclone chamber so as to form the spirally-extending primary cyclone channel together with the surrounding wall; one end, serving as a crude ash inlet, of the primary cyclone channel is communicated with the primary cyclone chamber; the other end, serving as a primary ash outlet, of the primary cyclone channel is communicated with the primary dust collection chamber;the secondary cyclone separator comprises a cyclone in which a secondary cyclone channel is arranged; the inlet of the secondary cyclone channel is communicated with the primary cyclone chamber, is positioned above the crude ash inlet and is opposite to the crude ash inlet; and the outlet of the secondary cyclone channel is communicated with the air outlet and the secondary dust collection chamber. According to the invention, the crude ash in dust can be prevented from rising, and dust and ash can be excellently separated with high efficiency.
