Problems solved by technology

[0004] The commonly used impact air sampler has a large limit on the air flow rate when used. When the air flow rate is high, the sample liquid in the sampler is easy to splash upward under the impact of the high-speed air flow, and is drawn out through the suction port, resulting in sampling The loss of liquid and air samples is not conducive to long-term sampling of air microorganisms

Abstract

The invention discloses an impact-type air sampler, comprising a sampling body and a limiting mechanism. The air extraction pipe works so that the outside air enters the inner cavity of the sampling body through the air intake pipe, and the air entering through the air intake pipe will impact the sampling liquid. When the sampling liquid splashes upward, part of the splashed sampling liquid is blocked by the limiting element and flows back into the inner cavity of the sampling body, and part of the splashed sampling liquid falls to the top of the limiting element. Since the limiting element is inclined toward the bottom of the sampling body, The sampling liquid still flows back into the inner cavity of the sampling body under the diversion effect of the limiting element, which effectively reduces the loss of the sampling liquid, meets the needs of long-term sampling, and reduces the loss of air samples at the same time. At the same time, the impact-type air sampler of the present invention can meet the sampling requirements in the case of a large air flow rate, which is beneficial to improve the sampling rate of air microorganisms and improve the accuracy of sampling results.

Description

technical field [0001] The invention relates to the technical field of air sampling detection equipment and its surrounding supporting facilities, in particular to an impact air sampler. Background technique [0002] Humans, animals and plants, as well as microorganisms in the soil can be dispersed in the air through droplets or dust, so that the air contains certain types and quantities of microorganisms. In theory, there is generally no pathogenic microorganism in the air, but in the air near hospitals, veterinary hospitals and livestock and poultry stables, aerosols of pathogenic microorganisms are often suspended, and healthy people or animals are often infected by inhalation. Air polluted by pathogenic microorganisms can often become the source or medium of pollution, causing the epidemic of infectious diseases. Therefore, the detection of air microorganisms is of great significance for the prevention and control of infectious diseases and the supervision and protectio...
