Automatically switched air filtering device

Abstract

The invention discloses an automatically switched air filtering device. The automatically switched air filtering device comprises an air inlet passage installed in a wall and communicated with an outdoor part. The air inlet passage is internally provided with a fan. The air inlet of the air inlet passage is provided with a filtering net. The air outlet of the air inlet passage is connected with an air outlet passage I and an air outlet passage II. The air inlet passage is internally provided with a pneumatic air door I at the air outlet passage I and a pneumatic air door II at the air outlet passage II. The air outlet end of the air outlet passage I is successively connected with a filtering device I and an electronic air cleaning device. The air outlet end of the air outlet passage II is connected with a filtering device II. The air outlet ends of the air outlet passage I and the air outlet passage II are communicated to the indoor space. The automatically switched air filtering device is capable of detecting the sundries components in the air by using a detecting device, and automatically distinguishing and processing by the different passages, so the efficiency and quality of the air purification are improved, the waste of electric power resources is avoided, and the green and environment-friendly requirements of energy conservation and emission reduction are satisfied.

Description

technical field [0001] The invention relates to the technical field of air purification equipment, in particular to an automatic switching air filter device. Background technique [0002] With the rapid development of industrial society and the gradual improvement of people's living standards, air quality is increasingly concerned by everyone, especially the increasing air pollution and the extensive use of interior decoration materials, how to purify people's lives, work and other spaces. Air quality has increasingly become a topic worthy of research and discussion. At present, there are many factors that affect indoor air pollution in people's living and office, including harmful gas or odor pollution caused by excessive decoration and the use of inferior materials, as well as impurities such as dust, heavy metals, and inhalable particles caused by rain in the air quality. Pollution also includes hair, bacteria, dust, organic gas or allergens in special environments. For ...

Problems solved by technology

However, the purification principle and effect of air purification equipment on the market today are relatively single, so it cannot achieve the effect of comprehensive filtration of various pollutants, or use a variety of purification devices to continuously function to achieve the effect of comprehensive filtration. For areas with relatively good air quality or period of time, there is a situation that most of the filter system does not work effectively, wasting electric energy
