A circular fresh air purifier installed on glass windows or glass walls

technical field

The utility model relates to a fresh air purification device, in particular to a circular fresh air purifier.

Background technique

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. According to data, in 2013, only 5 of the 74 major cities in the country had an annual average concentration of PM _2.5 below 35ug/m ³ . 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, facing severe internal and external troubles. It is very important to purify indoor air and ensure indoor fresh air volume. The conventional way of ventilation is to open the window or use the fresh air system to ventilate the indoor air. Open windows for ventilation, which is greatly affected by the external environment and cannot be controlled. In winter and summer or when the air pollution is serious, it is not suitable to open windows; although more and more fresh air fans are used, the cost of fresh air systems is high, the installation is more complicated, and the volume of the main unit is relatively high. It is relatively large and has certain requirements for installation space and location. In addition, it needs to lay pipelines. It is not suitable for rooms that have been decorated and have small areas. These have brought a lot of inconvenience to users.

The quality of indoor air is a livelihood issue that is generally faced and concerned by urban residents in my country at this stage, and it is related to the health and vital interests of hundreds of millions of people. In order to improve the air quality of people's living and working places, there is an urgent need for ventilation equipment with filtering performance. Looking at the development status of fresh air systems at home and abroad in the past ten years, the technology of fresh air systems faces the following challenges: 1) comfort, fresh air systems installed indoors require low noise and controlled airflow; 2) dust removal, with outdoor 3) Safety, the fresh air system should not produce harmful by-products while treating the fresh air; 4) Aesthetics, the fresh air system can realize its functions At the same time, it does not destroy the beauty and integrity of the inside and outside of the building; 5) Intelligent, the fresh air system needs to be able to intelligently adjust and control according to the indoor air quality.

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 the workload is 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 air blower 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.
