Planktonic microorganism detection device

Abstract

The present invention provides a device for detecting planktonic microorganisms, which includes: an air flow path through which air containing planktonic microorganisms flows; a first body disposed on one side of the air flow path and having a first space and the second space part; the second body is arranged on the other side of the air flow path, and is provided with a trapping part for trapping the planktonic microorganisms; the light emitting part is arranged in the first space part for irradiating light of a predetermined wavelength region toward the trapping portion; and a light receiving portion disposed in the second space portion for detecting fluorescence generated from light acting on riboflavin contained in the planktonic microorganisms Signal: a first path of light from the light-emitting part toward a point of the trapping part and a second path of a fluorescent signal from a point of the trapping part toward the light-receiving part cross each other.

Description

technical field [0001] The invention relates to a device for detecting planktonic microorganisms. Background technique [0002] In order to achieve energy saving, recent buildings minimize the introduction of outside air and are airtight, so the pollution of indoor air tends to be serious. Therefore, various legal regulations on indoor pollutants have been gradually strengthened. [0003] The indoor pollutants may include: 1) particulate pollutants such as fine dust and asbestos, 2) gas phase pollutants such as carbon dioxide, formaldehyde, volatile organic compounds (VOC, volatile organic compounds), and 3) viruses, molds, bacteria, etc. biological pollutants. [0004] In particular, said biological pollutants have a bad effect on the user's health. Recently, a technique for detecting the amount of such biological pollutants and purifying indoor air has been developed. [0005] Prior literature information related to such techniques is as follows. [0006] 1) First pri...

AI Technical Summary

Problems solved by technology

[0011] 1) The planktonic microorganism detection device of the prior art requires a more complex structure and more components, and due to the use of expensive lasers and lenses, etc., more costs need to be invested in the production of the device

[0012] 2) In addition, the planktonic microorganism detection device in the prior art has a large volume, and needs to be located in a specific place as a single device, so there are limitations in specific household appliances or portable devices

[0013] 3) In addition, in order to measure the amount or concentration of planktonic microorganisms, it is necessary to carry out additional fluorescent treatment on planktonic microorganisms, so there are difficulties in the process
