A window-hung air purification device

Abstract

The invention discloses a window-hanging air purification device, which comprises: a sealed shell, a circle of connecting slots is arranged on the outside, air inlets are symmetrically arranged on the rear side up and down; The connecting block is connected with the connecting slot; the annular filter is arranged in the middle of the sealing shell; and the annular cleaning brush. The present invention purifies the air in the room by introducing fresh air from the outside to exchange the dirty air in the room. The device is installed on the push-pull window through the window frame sealing strip on the outside, which is more convenient to install and use. Filtration and purification, the ring-shaped filter screen provides a larger filtration area in a limited space, thereby improving the filtration and purification efficiency of the device, and the outside of the ring-shaped filter screen is equipped with an automatic cleaning structure, which can be cleaned by itself to prevent the ring-shaped filter screen from dust Excessive clogging, no need for manual cleaning, more convenient to use.

Description

technical field [0001] The invention relates to air purification equipment, in particular to a window-hanging air purification device. Background technique [0002] Air purifiers refer to products that can absorb, decompose or transform various air pollutants, generally including PM2.5, dust, pollen, odor, decoration pollution such as formaldehyde, bacteria, allergens, etc., to effectively improve air cleanliness. There are many different technologies and media in an air purifier that enable it to provide clean and safe air to the user. The applicant found that the existing air purification devices often need to work in a confined space to purify the air in the confined space, but after the air in the confined space is breathed by the human body for a period of time, the carbon dioxide content will continue to rise, and the oxygen content will continue to increase. Therefore, the best way to purify the air is often to introduce fresh air, and the filter structure of ordinar...

Problems solved by technology

The applicant found that the existing air purification devices often need to work in a confined space to purify the air in the confined space, but after the air in the confined space is breathed by the human body for a period of time, the carbon dioxide content will continue to rise, and the oxygen content will continue to increase. Reduced, so the best way to purify the air is often to introduce fresh air, and the filter structure of ordinary air purification devices will often be blocked after a period of use, requiring manual cleaning
