Figure 1 Figure 2 Correction 1982. 2. 8 - The claims for utility model registration and the brief description of the drawings shall be amended as follows. O Utility Model Registration Claims A tangential intake port adjacent to the open end and disposed on the side wall, a dust discharge port adjacent to the other end, and a clean air outlet located at the center thereof while closing the other end. A filter element sized to form an annular space between the inner wall and the inner wall is housed and held in a cylindrical housing having an end cover provided at the inner wall thereof, and the inner side thereof communicates with the outlet, so that the intake air flows into the filter element. A centrifugal separation system with a filter and a cover tube that surrounds the element in close proximity to prevent direct contact with the element, and a spiral path section that is disposed in the annular space on the suction side so as to spirally guide incoming air to the other end. In the staged air purifier, the cover tube and the spiral path section are integrally molded, and the tube end is shaped to also serve as a gasket for the cover for sealing the open end of the adjacent housing, and is detachably fitted together with the cover.

Claims (1)

[Scope of utility model registration request] a tangential inlet adjacent to the open end and disposed on the side wall; a duct outlet adjacent to the other end; and an end cap that closes the other end and has a clean air outlet in the center thereof. A large filter element, which forms an annular space between it and a closed wall, is housed and held in a cylindrical housing with a closed wall so that the inside thereof communicates with the outlet, and the filter element is arranged so that the intake air does not come into direct contact with the filter element. A two-stage air purifier using centrifugal separation and a filter, which is equipped with a cover tube that surrounds the element in close proximity to the element, and a spiral path section that is arranged in an annular space on the suction side that guides incoming air in a spiral shape toward the other end. The cover tube and the spiral path piece are integrally molded, and the tube end is shaped to also serve as a gasket for the cover for sealing the open end of the adjacent housing, and is removably fitted together with the cover. Centrifugal separation mechanism in a two-stage air purifier.
