Abstract

A cyclone separator is provided. The cyclone separator includes: a cyclone, an end cover of the cyclone separator, a filter and a wind guiding cylinder. The cyclone has an open end and a bottom wall defining an inlet of the cyclone separator therein. The end cover of the cyclone separator is disposed over the cyclone and defines an outlet of the cyclone separator therein. The filter has an upper end communicating with the outlet of the cyclone separator and a lower end extended into the cyclone. The wind guiding cylinder has a lower end communicating with the inlet of the cyclone separator, a closed upper end and a side wall defining a vent communicating with the cyclone.

First claim

2 . The cyclone separator according to claim 1 , wherein a wind guiding plate and a wind shielding plate are disposed within the cyclone, at least a part of the wind guiding plate is extended upwards in a spiral shape, the wind shielding plate is disposed above the vent, and the wind shielding plate is not higher than an upper edge of the wind guiding plate.

3 . The cyclone separator according to claim 2 , wherein the wind guiding plate is configured to have an annular shape and comprises:
a first plate body and a second plate body perpendicular to an axis of the cyclone respectively; a spiral wind guiding plate extended in the spiral shape in an up and down direction and having an upper end connected with the second plate body and a lower end connected with the first plate body; a connection plate parallel to the axis of the cyclone and having an upper end connected with the second plate body and a lower end connected with the first plate body.

4 . The cyclone separator according to claim 3 , wherein the first plate body is disposed at a lower edge of the vent, the wind shielding plate is disposed at an upper edge of the vent, the second plate body is in flush with the wind shielding plate, and the connection plate is disposed at a side edge of the vent.

5 . The cyclone separator according to claim 2 , wherein the wind guiding plate is the bottom wall of the cyclone, and the inlet of the cyclone separator is formed in the wind guiding plate.

6 . The cyclone separator according to claim 1 , wherein a wind inlet pipe communicating with the inlet of the cyclone separator is disposed at the bottom wall of the cyclone.

7 . The cyclone separator according to claim 1 , further comprising a cylinder body and a baffle, wherein the baffle is disposed within the cylinder body and configured to separate space within the cylinder body in an up and down direction, an upper portion of the cylinder body is configured as the filter and a lower portion of the cylinder body is configured as the wind guiding cylinder.

8 . The cyclone separator according to claim 2 , wherein the wind guiding plate has a height larger than or equal to a half of a depth of the wind guiding cylinder and less than or equal to a depth of the cyclone.

9 . The cyclone separator according to claim 2 , wherein the end cover of the cyclone separator is spaced from an upper edge of the cyclone, and a distance between the upper edge of the cyclone and the end cover of the cyclone separator is less than or equal to a height of the wind guiding plate.

10 . The cyclone separator according to claim 1 , wherein the filter is configured to have a cylinder shape, the cyclone is configured to have a cylinder shape whose center line is coincident with a center line of the filter, and a radius of the filter is less than or equal to a half of a radius of the cyclone.

11 .
