Abstract
Abstract A cyclone dust collecting apparatus comprises a deformable contaminants counterflow prevention member mounted to within 10 to 12 mm of the inner surface of the cyclone dust collecting apparatus. The deformable contaminants counterflow prevention member is soft enough to be elastically transformed to allow large contaminants to be drawn past it and drop into a dust collecting apparatus yet resilient enough so that it returns to its original shape after a large contaminant is passed.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
89 words
A cyclone dust collecting apparatus comprising: a cyclone body having an inner circumference; a grill mounted in the cyclone body and preventing dusts and contaminants centrifugally separated in a rotating stream from leaking out of the cyclone body; a contaminants counterflow prevention member formed of an elastically transformable material and engaged with a bottom end of the grill, and preventing the centrifugally separated contaminants from counterflowing; and a contaminants collection receptacle removably attached to the cyclone body collecting the centrifugally separated contaminants from air passing through the cyclone body.
Claim 2
Dependent Claim
89 words
A cyclone dust collecting apparatus comprising: a cyclone body having an inner circumference; a grill mounted in the cyclone body and preventing dusts and contaminants centrifugally separated in a rotating stream from leaking out of the cyclone body; a contaminants counterflow prevention member formed of an elastically transformable material and engaged with a bottom end of the grill, and preventing the centrifugally separated contaminants from counterflowing; and a contaminants collection receptacle removably attached to the cyclone body collecting the centrifugally separated contaminants from air passing through the cyclone body.
Claim 3
Dependent Claim
31 words
The cyclone dust collecting apparatus according to claim 1 , wherein the contaminants counterflow prevention member is made of a rubber material of 40 Shore hardness degrees (40 A) and below.
Claim 4
Dependent Claim
33 words
The cyclone dust collecting apparatus according to claim 1 , wherein the separation distance between the contaminants counterflow prevention member and the inner circumference of the cyclone body is 10 through 12 mm.
Claim 5
Dependent Claim
30 words
The cyclone dust collecting apparatus according to claim 1 , wherein the separation distance between the contaminants counterflow prevention member and the contaminants collection receptacle is 8 through 10 mm.
Claim 6
Dependent Claim
79 words
The cyclone dust collecting apparatus according to claim 1 , wherein a protrusion part is configured at a lower end part of the grill with which the contaminants counterflow prevention member is engaged, and a groove part is configured at a position corresponding to the protrusion part around the contaminants counterflow prevention member such that the groove part and the protrusion part are engaged with each other of the contaminants counterflow prevention member to be fit in the grill.
Claim 7
Dependent Claim
84 words
The cyclone dust collecting apparatus according to claim 1 , wherein the contaminants counterflow prevention member is made of a material, sufficiently pliable to allow objects greater in size than the separation distance between the contaminants counterflow prevention member and the inner circumference of the cyclone body, to deform the material and pass around the counterflow prevention member by being pulled there through by air current drawn through the cyclone dust collecting apparatus by a vacuum source coupled to the cyclone dust collecting apparatus.
