Problems solved by technology

However, in some new application fields, such as fresh air equipment, vehicle-mounted purifiers, etc., there is a need to detect two isolated environments, such as a purified environment and a natural environment, which cannot be achieved by existing air particle sensors. The detection of two different environments cannot meet the needs very well

Abstract

The invention provides a particle matter concentration detecting device and method and an air processing device. The particulate matter concentration detecting device comprises a main body. A detecting air duct and an air duct control device are arranged in the main body. A photoelectric detector and a drafting mechanism are arranged in the detecting air duct. The main body is further provided with a first air inlet part, a second air inlet part, a first air outlet part and a second air outlet part. The first air inlet part and the second air inlet part are connected with the air inlet end ofthe detecting air duct through the air duct control device respectively. The first air outlet part and the second air outlet part are connected with the air outlet end of the detecting air duct through the air duct control device respectively. The air duct control device is used to selectively control one of the first air inlet part and the second air inlet part to communicate with the air inlet end, and selectively control one of the first air outlet part and the second air outlet part to communicate with the air outlet end. The particle matter concentration detecting device provided by the invention can accurately detect the particle matter concentration of two environments, and has the advantages of high detection precision and compact structure.

Description

technical field [0001] The invention relates to the field of air detection, in particular to a particle concentration detection device, method and air processing device. Background technique [0002] Common air particle sensors currently on the market have a negative pressure air outlet and an air inlet, which can only measure fine particles in the air in one environment. However, in some new application fields, such as fresh air equipment, vehicle-mounted purifiers, etc., there is a need to detect two isolated environments, such as a purified environment and a natural environment, which cannot be achieved by existing air particle sensors. The detection of two different environments cannot meet the needs very well. Contents of the invention [0003] Embodiments of the present invention provide a particle concentration detection device, method and air treatment device for detecting particles in air in different environments. [0004] In order to achieve the above object, ...
