Abstract
An air cleaner structure for blocking an inflow of debris to prevent the debris from inflowing into an engine intake passage of an air cleaner housing when replacing a filter includes a rotator fixing the filter and a filter cover to the air cleaner housing and generating a rotating force to open and close the engine intake passage. An engine intake passage door opens and closes the engine intake passage by the rotating force of the rotator. A connector has one end connected to the rotator and another end connected to the engine intake passage door to deliver the rotating force to the engine intake passage door.
Claims2
An operation method of an air cleaner structure for blocking an inflow of debris, the method comprising steps of:
- a first locking step of using a locker to fasten a nut with a rod;
- a first rotating step of rotating the nut to allow the butterfly plate to close an engine intake passage;
- a first disengaging step of disengaging, by the locker, the nut fastened with the rod from the rod;
- a withdrawing step of rotating the nut to withdraw the nut from the rod;
- and
- a replacing step of replacing a filter,
- wherein a first opening and closing gear which is directly or indirectly connected to the rod, a first connection gear, a flexible cable, a second connection gear, and a second opening and closing gear rotates when rotating force of the nut is delivered to the rod, and
- wherein a hinge shaft which is directly or indirectly connected to the second opening and closing gear and the butterfly plate rotates to close the engine intake passage.
