Abstract

The invention discloses a round fresh air purifier installed on a glass window or a glass wall. The round fresh air purifier comprises a main equipment body installed on the inner side of the glass window or the inner side of a glass wall chamber; the main equipment body comprises a bottom disc fixed to the inner side of the glass window or the inner side of the glass wall chamber; one side of the bottom disc is provided with an outer rotor draught fan, rough-efficiency and medium-efficiency/high-efficiency filtering units fixed to the bottom disc, and a chemical pollutant adsorption unit; the other side of the bottom disc is provided with an installation part, and the installation part comprises an inner sleeve and an outer sleeve which are fixed to the bottom disc; the inner sleeve and the outer sleeve are connected through threads; an indoor fixing clamping plate and a folding outdoor fixing clamping plate are fixed to square holes in the glass window or the glass wall; a fresh air supplying channel is formed from the inner sleeve, a metal filtering screen, a fresh air adjusting valve, the outer rotor draught fan, the filtering units to an air supplying port; and an air returning channel is formed from an indoor air returning hole, the outer rotor draught fan, the filtering units to the air supplying port. According to the round fresh air purifier, the size is small, noise is low, a filtering core is easier to replace, and the round fresh air purifier has the functions of both an air purifier and a fresh air machine.

Description

technical field [0001] The invention relates to a fresh air purification device, in particular to a circular fresh air purifier. Background technique [0002] Indoor air quality greatly affects people's quality of life, health and productivity. At present, China's domestic air pollution is becoming more and more serious. The data shows that in 2013, only 5 of the 74 major cities in the country had PM 2.5 The annual average concentration reaches 35ug / m 3 the following. At the same time, the concentration of pollutants such as formaldehyde, VOCs and ammonia in some newly renovated rooms or some rooms that have been used for a period of time is often higher than the national standard threshold. In recent years, the airtightness of domestic buildings has been greatly improved, and the fresh air entering the room through infiltration cannot meet the requirements of reducing the concentration of indoor pollutants. However, contemporary humans spend 90% of their time indoors, fa...

Problems solved by technology

[0004] At present, the common fresh air fans and ventilators are mostly wall-mounted. The disadvantages of the wall-mounted type are: 1) The installation location must be the outer wall or close to the outer wall, which is not suitable for the inner room; 2) The wall structure needs to be destroyed during the installation process. Not only is the workload heavy, the cost is high, it is unhygienic, and it is easy to bring safety hazards; 3) It is difficult to repair the wall after the fresh fan or ventilator is disassembled

Compared with the wall-mounted type, window-type fresh air fans or ventilators have the advantages of less damage to the room and easy installation. However, the following problems generally exist in window-type fresh air fans and ventilators: 1) Large size, which affects lighting and aesthetics; 2. ) The air volume is small and the noise is high, so it is not suitable for use in quiet places, such as schools, offices, etc.; 2) It is inconvenient to install and disassemble and replace the filter element
