Abstract
The utility model relates to an air microorganism sampler which aims to solve the problems that when an existing air microorganism sampler is used for sampling, micro-particles enter a downstream detector under the action of airflow, and the downstream detector is easily damaged. The air microorganism sampler comprises a plurality of air inlet pipes, an upper seat, a membrane sealing ring, a membrane, an inlet through pipe, a micro-filtration shell, a multilayer microporous filtration membrane, an air outlet pipe and a lower seat, the upper seat and the lower seat are vertically arranged, the upper seat is connected with the lower seat in a threaded manner, a cavity is formed between the upper seat and the lower seat, the air inlet pipes are arranged on the upper seat and communicated with the cavity, the membrane is arranged in the cavity and fixed between the upper seat and the lower seat through the membrane sealing ring, the inlet through pipe is connected onto the lower seat and communicated with the cavity, the lower end of the inlet through pipe is communicated with the micro-filtration shell, the multilayer microporous filtration membrane is arranged in the micro-filtration shell, and the air outlet pipe is communicated on the lower portion of the micro-filtration shell. The air microorganism sampler is used for sampling air microorganisms.
Description
Technical field
The utility model relates to a kind of microorganism sampler, is specifically related to a kind of air microorganism sampler.
Background technology
Microbes in air is mainly derived from soil, water surface, animals and plants, human body and activity in production, sewage disposal etc., and its tissue concentration is unstable, and kind is various, and bacterium, fungi, virus, phage etc. are arranged.Microbes in air exists with aerosol form, and aerosol is solid-state or the liquid microparticle is suspended in dispersion system in the gaseous media.The dust with microorganism that suspends in the air, particulate matter or liquid droplets are exactly microbial aerosol.Microbes in air how much be the important indicator of Air quality, also be the significant data of control and prevention of disease center monitors epidemic situation.Existing air microorganism sampler is when sampling, and microparticle enters the detected downstream instrument with airflow function, easily the detected downstream instrument is caused damage.
The utility model content
The purpose of this utility model is in order to solve existing air microorganism sampler in when sampling, and microparticle enters the detected downstream instrument with airflow function, easily the detected downstream instrument is caused the problem of damage, and then a kind of air microorganism sampler is provided.
The technical solution of the utility model is: air microorganism sampler comprises a plurality of inlet pipe, upper pedestal, the film phonograph seal circle, diaphragm, advance siphunculus, the micro-filtration housing, multi-layer microporous filter membrane, escape pipe and lower base, upper pedestal and lower base are arranged up and down, and upper pedestal is threaded with lower base, form chamber between upper pedestal and the lower base, a plurality of inlet pipe are arranged on the upper pedestal, and a plurality of inlet pipe are communicated with chamber, diaphragm places in the chamber and by the film phonograph seal circle and is fixed between upper pedestal and the lower base, advancing siphunculus is connected on the lower base, and advancing siphunculus is communicated with chamber, the lower end of advancing siphunculus is communicated with the micro-filtration housing, be furnished with multi-layer microporous filter membrane in the micro-filtration housing, escape pipe is communicated with the bottom at the micro-filtration housing.
The utility model compared with prior art has following effect: air microorganism sampler of the present utility model intercepts microparticle outside the detected downstream instrument by filtering layer by layer, has avoided the damage that the detected downstream instrument is caused for particulate matter.In addition, air microorganism sampler of the present utility model is simple in structure, and is easy to use, is convenient to manufacture.
