A multidirectional dust adsorption type air quality detection device disclosed by the present invention comprises an air quality sensor and an external protection installation shell, the installation shell is cylindrical, the upper and lower ends of the installation shell are respectively provided with an air inlet and an air outlet, and the top of the installation shell is provided with a wind direction plate. Air inlet grilles are evenly distributed in the air inlet, scaly movable blade plates are arranged on the side edges of the air inlet grilles in an attached mode to adjust the diameter of the air inlet in an opening and closing mode, then filter screens are arranged on the outer sides of the air inlet and the air outlet, and airflow in the installation shell sequentially passes through the air inlet, the air quality sensor and the air outlet from top to bottom. According to the multidirectional dust adsorption type air quality detection device, multidirectional air inlet can be flexibly adjusted along with wind through the wind direction plate and the movable blade plate structure, the whole cylindrical structure can be conveniently matched with the wind direction plate to move to drive a sweeping mechanism to sweep in a surrounding mode, and the device can be conveniently used outdoors for a long time.
Description
technical field [0001] The invention relates to the related technical field of air quality detection, in particular to a multi-directional dust adsorption type air quality detection device. Background technique [0002] Air quality detection is mainly to detect and analyze a large number of pollutants in the air. In addition to floating dust particles, it mainly detects air pollutants such as sulfur dioxide, nitrogen monoxide and hydrocarbons, and detects and analyzes corresponding gas pollutants. At this time, a large amount of dust particle pollutants will adversely affect the gas detection. [0003] Most of the existing air quality detection devices are ordinary flat air inlets, and dust is easy to adhere to the air inlet, which is not convenient for cleaning. There is also a kind of air quality detection device in a building with the Chinese patent publication number CN209894782U, which can be absorbed by wind Simply clean the dust attached to the detection module, but ...
