Description

[Detailed description of the invention] This invention relates to a contaminated air purifier, and more specifically, it purifies indoor air by removing air pollutants generated in a car, residence, office, work room, etc. It is related to the device.

In recent years, as buildings have become more airtight, residences, offices, conference rooms, etc. are exposed to cigarette smoke and table cooking odors, and work rooms are exposed to odors such as smoke, etc. It has become necessary to remove various types of dust with odors, and cigarette smoke is also becoming a problem in automobiles, trains, airplanes, and the like.

Various air purifiers have been proposed to remove such air pollutants, but many conventional air purifiers do not have a closing mechanism on the air suction port, so they do not allow air to escape while the operation is stopped. There is a drawback that gaseous components in the air pollutants adsorbed inside the purifier emanate.

In addition, air purifiers have been devised that have an opening/closing lid on the air suction port, but the lid protrudes outward during operation and restricts air flow, so it cannot be used for anything other than special purposes. There was a drawback that it got in the way.

The purpose of the present invention is to eliminate such drawbacks of conventional devices, and to provide an air purifier that does not release adsorbed gaseous pollutants even when the system is stopped, has excellent air purifying effects, and is easy to operate.
