Problems solved by technology

But unfortunately: the air microbial sampler in the prior art only adopts AC power supply, is large in size and heavy in weight, it is very inconvenient for the staff to carry it, and the sampling location and environment are greatly restricted. This traditional sampling method is due to The limitation of sampling not only poses great potential hazards to the personal safety of experimenters, but also cannot well represent the real results of the microbial environment in an area
On the other hand, in the air filter device of the air sampler in the prior art, the filter membrane is usually arranged at the inlet, so the air cannot be filtered effectively, and effective data cannot be obtained.
On the other hand, in the prior art, the pulsating air flow has a great influence on the flow detection sensor, which will distort the measurement results

Abstract

The invention relates to the technical field of microbial air sampling, in particular to a miniature personal microbial air sampler. The invention is characterized in that the sampler mainly comprises a gas circuit part (1), a power source part (2), a signal processing part (3) and a mechanical part (4), wherein a sampling head of the gas circuit part adopts a microporous membrane filter, and a membrane is arranged in the microporous membrane filter. The invention mainly solves the problem that the current samplers are large in volume and has heavy weight arising from only using an alternating current (AC) power to carry out power supply, therefore, the current samplers are inconvenient to carry by workers, and the sampling sites and environments thereof are greatly restricted. The invention has the advantages of easy carrying, small volume, light weight, high sampling efficiency, and accurate and reliable monitoring results.
