This application claims priority under 35 U.S.C. § 119 to Korean Application No. 10-2024-0077098, filed in Korea on Jun. 13, 2024, whose entire disclosure is hereby incorporated by reference.

An air purifier is disclosed herein.

An air purifier is a device that filters and discharges air inside of a predetermined space to reduce, for example, dust and bacteria in the air in a corresponding space, for example, an indoor space. The air purifier filters out foreign substances through an air flow and discharges air from which the foreign substance is removed.

In order to suction the air in a wide range of the corresponding space and to discharge the filtered air, a cylindrical case may be provided having an inlet on a circumferential surface thereof, and from which filtered air is discharged at a top thereof. However, a device that switches a separate flow to a top to which the filtered air is discharged is provided in order to discharge the filtered air to a long-distance area of the corresponding space to discharge the filtered air to a wide area of the corresponding space.

Korean Patent Unexamined Publication No. 10-2018-0000121, which is hereby incorporated by reference, discloses a blowing device that blows air to a top from a lower circumferential surface, and a booster which is disposed above the blowing device and switches the flow of the air discharged to the top. However, a structure is provided in which the booster is coupled and fixed to an upper side of a body. The booster is a structure in which a separate fan and a plurality of electronic devices are disposed inside thereof, and a position or placement may be changed based on the body. Accordingly, structure is disclosed in which the booster is coupled to the blowing device and it is difficult for a user to separate the structure for stability of a product. That is, there is a problem in that it is difficult for the user to separately manage the booster.
