Description

Portable air clean hood {PORTABLE AIR CLEAN HOOD}

This invention It relates to a portable air purifying hood. More specifically, it allows for easy installation and replacement of filters that filter out pollutants, captures oil vapor generated when cooking food, etc., and is easy to carry. It relates to a portable air purifying hood that can be freely moved and easily adjusted to an appropriate position.

In general, an air purifier refers to a device that sucks in polluted air, purifies it, and then discharges the purified air.

Such an air purifier may include a suction grill installed at the intake port of the main body to suck in external air, a fan that causes a flow of sucked air, and a filter that removes dust and odor components contained in the sucked air.

These air purifiers suck in polluted air with a fan and can collect fine dust or deodorize odors through a filter.

Accordingly, air purifiers are recognized and used as the most effective device for removing pollutants from indoor air.

However, conventional air purifiers do not provide additional functions other than the function of purifying the air, and have a problem in that they cannot effectively deal with oil vapor generated during cooking, such as grilling meat or fish at home.
