Claims

[Scope of utility model registration request]

A chrysanthemum-shaped folded origami paper is wound around the outer circumference of the inner tube of a porous cylinder, and an end plate is glued above and below it to form a main element.A pre-filter made of coarse material is arranged on the outside of the main element. In an air cleaner in which a plate is compressed by a cover and a body through an elastic material, a prefilter having a notch at a position almost opposite to the inlet pipe is a quasi-annular prefilter that has a plurality of annular grooves formed on the inner surface in contact with the outer periphery of the main element. The side wall of the body on the side of the notch has a suction hole in the center, and the suction hole along the side wall. A through hole is formed at a more symmetrical position, a box-shaped communication path is provided on the outside of the through hole, and the sliding portion of the prefilter slides between the through hole and the side wall of the body. Air cleaner equipped with a movable prefilter.
