Abstract
The invention discloses a negative air ion-based bacterium killing testing device. The negative air ion-based bacterium killing testing device comprises a negative ion generator, a plurality of reaction chambers, and bacterial culture dishes placed inside the reaction chambers, wherein the negative ion generator comprises a plurality of output ends; each output end is correspondingly inserted intoeach reaction chamber; negative high voltage is generated in the reaction chambers and air in the reaction chambers is ionized to generate negative ions; the generated negative ions diffuse and interact with bacteria in the bacterial culture dishes; the bacterial culture dishes are further connected with a grounded charge transfer component. The negative ions are generated on the basis of a corona method for bacterium killing testing, so that the occurrence of side effects such as excessive charge accumulation and electrostatic discharge is effectively avoided while generation and release ofa large amount of negative ions are guaranteed; through full contact and interaction of the negative ions generated by the corona method with the bacteria in the reaction chambers, in the case of eliminating interference factors, the bacterium killing efficiency of the negative ions is effectively investigated by virtue of parallel experiments.
Description
technical field [0001] The invention relates to the technical field of sterilization testing, in particular to an air negative ion bacteria killing testing device. Background technique [0002] Negative ions, known as "air vitamins", play a pivotal role in human health and environmental purification due to their unique properties and beneficial effects. Related research has continued for decades and has yielded fruitful results. Since Elster and Gertel discovered the existence of negative air ions in 1889, many studies have reported the generation of negative ions and the subsequent chemical reactions. When a part of the neutral molecule is under the external action, the outer electrons in it will escape from the nucleus to form free electrons, and these free electrons will continue to generate a large number of negative ions in a certain space by being captured by molecules or reacting with molecules. Since the life of negative ions is greatly affected by the external envi...
