Description

Technical Field

[0001] The utility model relates to the technical field of air detection, in particular to an air collecting device for air detection. Background Art

[0002] In order to detect the quality of the air environment, it is necessary to collect air regularly, and then detect the components in the air to determine the air quality. In the existing technology, mechanical equipment is mostly used to collect air. Generally, a vacuum pump is used to introduce the outside air into the collection bag. Since the vacuum pump and the collection bag need to be connected, and then the equipment is placed at the collection point, the air in the vacuum pump and the pipeline does not change with the movement of the equipment, resulting in the collection bag being directly filled with air, which is mixed with the air in the vacuum pump and the pipeline, causing errors in the collection of air samples and unable to accurately reflect the true air quality of the collection point.

[0003] However, existing air collection devices have certain drawbacks. Due to the differences in air quality in different geographical locations, it is necessary to collect several gases independently during air detection. However, existing air collection devices are not convenient for replacing collection bottles for collection. Secondly, existing air collection devices cannot remove dust from the air. Air dust will affect the service life of the collection device, thus having a certain impact. Therefore, an air collection device for air detection is urgently needed to solve the above problems.
