Description
Technical Field
The utility model relates to the technical field of air microorganism sampling, in particular to an air microorganism sampler.
Background
The microorganisms in the air mainly originate from soil, water surfaces, animals, plants, human bodies, production activities, sewage treatment and the like, the tissue concentration of the microorganisms is unstable, the species are various, and bacteria, fungi, viruses, phage and the like are included. The microorganisms in air are present in the form of an aerosol, i.e. a dispersion of solid or liquid microparticles suspended in a gaseous medium. Airborne dust, particulate matter or liquid droplets carrying microorganisms are known as microbial aerosols. The quantity of microorganisms in the air is an important index of air quality and is also important data for monitoring epidemic situation by a disease prevention and control center.
In order to sample and detect microorganisms in the air, the air microorganism sampler is needed to be used, for example, a Chinese patent document with the prior patent publication number CN 219174496U discloses a full-automatic air microorganism sampler, which comprises an equipment box, the air inlet is formed in the top of the equipment box, a dustproof separation net is sleeved at the top of the air inlet screen through rivets, two turnover baffles are connected in an internal symmetry mode through hinges, springs are welded at one ends, close to each other, of the bottom ends of the two turnover baffles, the other ends of the springs are respectively obliquely extended to two sides of the air inlet, a supporting plate is mounted in the equipment box through bolts, a supporting plate is vertically welded at the top of the supporting plate and positioned in the equipment box, a plurality of partition plates are mounted between the two supporting plates through bolts at equal intervals, a collecting box is arranged at the bottom end of the partition plates, a motor is mounted at the bottom end of the equipment box through bolts, and fan blades are connected at the top of the motor through driving shafts.
The above patent documents have certain technical drawbacks in practical use, such as:
With reference to fig. 2 of the patent document, a motor is fixedly installed at the bottom of an inner cavity of the equipment box, and fan blades are fixedly installed on an output shaft of the motor.
