Being in an air polluted room for a long time, the health care pillow is easy to cause lassitude, unsmooth breathing, inattention and reduction of metabolism capability, and serious people can also cause cancers. Especially children are in the development stage of the body, and the immune system is fragile and is more easily damaged by indoor air pollution, so that the indoor air disinfection is enhanced, the indoor air quality is improved, and the human health is promoted.
The current common air disinfection methods comprise an ozone method, an ultraviolet irradiation method and a chemical disinfection method, and the disinfection methods can kill pathogenic microorganisms, have high action speed and low effective concentration and obtain better disinfection effect. However, the disinfection methods have the problems of high toxicity, strong corrosiveness, high irritation and the like; improper use can seriously affect the health. All the personnel are required to leave the site during the ozone disinfection and the ultraviolet irradiation disinfection, and protective measures are required in the operation process; chemical disinfectants such as peroxyacetic acid, lactic acid, hydrogen peroxide and the like can not eliminate peculiar smell quickly after being disinfected, and have the risk of accumulation poisoning and the like on human bodies after being used for a long time. The traditional medicinal plants have good antibacterial and antiviral effects, can be used for preparing a plant source air disinfectant, can disinfect indoors in an environment-friendly and pollution-free manner, and has important social significance in research and development of the plant source air disinfectant.
Coptis chinensis Franch (Coptis chinensis Franch.) belongs to Ranunculaceae and Coptis chinensis is a perennial herb, and is a traditional Chinese medicinal material in Shennong Ben Cao Jing. Is bitter in taste and cold in nature, and has the effects of purging fire, detoxifying, clearing heat, eliminating dampness and the like. The main active components of the coptis chinensis comprise alkaloids such as berberine, coptisine, methyl coptisine, tetrandrine and the like, and the coptis chinensis has good antibacterial effect.
Turmeric (Curcuma longa L.) is a traditional Chinese medicinal material in China, and has the effects of resisting inflammation, resisting virus, resisting oxidation, reducing blood fat, protecting liver, benefiting gallbladder, resisting cancer and the like. The main active molecule in the turmeric is curcumin, and researches show that the turmeric curcumin and derivatives thereof can resist various viruses such as influenza virus, enveloped virus, coronavirus, respiratory syndrome virus and the like,
chinese invention patent publication No. CN 104255835A discloses that chamomile essential oil, peppermint oil, cinnamon essential oil, honeysuckle, patchouli essential oil, dandelion, coptis, aloe, salvia miltiorrhiza and the like are taken as raw materials to prepare a disinfectant in an air chamber, and Chinese invention patent publication No. CN 104604956A discloses an air chamber disinfectant prepared by taking patchouli essential oil, phellodendron, scutellaria, angelica dahurica, fructus cnidii, sophora flavescens, coptis, folium artemisiae argyi, astragalus membranaceus, magnolia officinalis, fructus forsythiae, liquorice, white, honeysuckle and the like as raw materials, and the disinfectant has the conditions of multiple traditional Chinese medicine components, complex process, unstable product quality and the like. Through patent search, no relevant research report that the coptis chinensis extract, the turmeric extract and the like are used as main components for producing the air indoor disinfectant is found at present.
