[0002] As residents become increasingly aware of their surrounding environment, a large number of products for environmental monitoring have emerged. For example, air quality monitors primarily detect harmful gases in the air in real time, but existing air quality monitors cannot reflect microbial risks. To accurately reflect microbial content, specialized equipment such as air impactors with six-stage sieves is needed to collect airborne microorganisms, which are then cultured in a laboratory for 48 hours. However, this method lacks real-time accuracy, making it impossible to control situations promptly when air quality risks arise. Existing bioaerosol detectors using ATP (adenosine triphosphate) fluorescence reaction can automatically collect airborne microorganisms, but these devices are expensive and bulky. Handheld ATP devices also exist, but they require a six-stage sieve impactor to collect airborne microorganisms, followed by swab testing, which is inconvenient. The cost and ease of use of existing microbial detection equipment do not meet residents' needs. Utility Model Content
