Outdoor fresh air ventilation device combined with air purifier

Abstract

The invention discloses an outdoor fresh air ventilation device combined with an air purifier. The outdoor fresh air ventilation device comprises a machine body, a purification box, a water tank and an air duct are arranged inside the machine body, the air duct is located between the purification box and the water tank, the outer wall of one side of the air duct is fixedly connected with a protective cover through bolts, moreover, the interior of the air duct is fixedly connected with a motor through bolts, one end of the motor is rotationally connected with an impeller through a rotating shaft, an indoor air lead-in pipe is arranged between the air duct and the water tank, and a mixed gas pipe is arranged between the water tank and the purification box. According to the outdoor fresh airventilation device, on one hand, carbon dioxide in gas is transferred and discharged through the solubility of water, so that the content of the carbon dioxide in indoor air is effectively reduced, onthe other hand, by introducing outdoor fresh air, indoor carbon dioxide concentration is effectively reduced, oxygen concentration is increased, the outdoor fresh air enters a room to effectively dilute and remove PM2.5 and gaseous pollutants in the room, and the purification efficiency is improved to a certain extent.

Description

technical field [0001] The invention belongs to the technical field of air purifiers, and in particular relates to an outdoor fresh air device combined with an air purifier. Background technique [0002] Air purifiers, also known as air fresheners and purifiers, refer to air pollutants that can absorb, decompose or transform various air pollutants (generally including PM2.5, dust, pollen, odor, decoration pollution such as formaldehyde, bacteria, allergens, etc.) ), home appliances that effectively improve air cleanliness. [0003] Existing air purifiers in the industry are suitable for air purification in confined spaces, which can effectively solve the problem of high concentration of PM2.5 and gaseous pollutants in indoor air, but cannot effectively solve the problems of high indoor carbon dioxide concentration and low oxygen concentration. Contents of the invention [0004] The purpose of the present invention is to provide an outdoor fresh air device combined with an...
