76 results about "Phytoncide" patented technology

Phytoncides are antimicrobial allelochemic volatile organic compounds derived from plants. The word, which means "exterminated by the plant", was coined in 1928 by Dr. Boris P. Tokin, a Russian biochemist from Leningrad University. He found that some plants give off very active substances which prevent them from rotting or being eaten by some insects and animals.

Natural air purifying system adopting forest factor as purification factor

The invention relates to a natural air purifying system adopting a forest factor as a purification factor. The natural air purifying system comprises an electric ion generator, an electric ion pulse energy enhancer, a negative oxygen ion releaser, a phytoncide box and an ion field generator, wherein the ion field generator comprises a first metal piece, a second metal piece and a piezoceramic piece, the first metal piece is connected with the output end of the electric ion generator through a conducting wire, and the second metal piece is connected with a zero-potential point through a conducting wire; the output end of the electric ion pulse energy enhancer is connected with the negative oxygen ion releaser. By adopting the natural air purifying system, the activity of the electric ion is enhanced, and ecological negative oxygen ions with small granularity and high activity are released. The phytoncide liquid is ionized under the effect of a strong ion field of the ion field generator and volatized in an accelerating manner in an ultramicron form due to the vibration of the piezoceramic piece, and the phytoncide liquid is combined with the negative oxygen ions in the volatizing process to be rapidly released into a space in a negative-ion particle form so as to sterilize and deodorize.
