Problems solved by technology

A large amount of toxic gas is discharged, which is extremely harmful to the human body and seriously pollutes the environment
The applicator can easily cause poisoning, coma, and even death
Toxicology experiments also show that these organophosphates are in the highly toxic range, leading to human liver and kidney dysfunction
[0004] Products currently on the market for preventing and killing fleas on domestic pets include pet collars and sprays. The products mainly use organophosphates or pyrethroids as active ingredients. Although these ingredients can drive and kill fleas, but Organophosphorus drugs are highly toxic substances, and pyrethroids are also of medium and low toxicity, which are harmful to humans, animals and the environment.

Embodiment Construction

[0022] Use 1 kilogram of Ling vanilla to dry the whole herb, and the loss on drying is less than 15%, that is, after 1000 grams of the Ling herb dry whole herb is baked in an oven at 105°C for 2 hours, its weight is not less than 850 grams. After being crushed by a pulverizer, pass through a 40-mesh sieve, put into a lidded container or reaction kettle, pour 5-7 kg of industrial grade ethyl acetate, soak for 18-28 hours, take the supernatant, and filter on a filter cloth .

[0023] After repeating this process for 3 to 5 times, the squeezing residue is filtered, the filtrate is combined, and the filtrate is pumped into the liquid storage tank with a vacuum pump;

[0024] The filtrate is pumped from the storage tank to the distillation tank, and concentrated under vacuum and reduced pressure at 55℃ and 0.06~0.07Mpa until the solvent is drained, and 50~80 grams of Ling vanilla ethyl acetate can be extracted. liquid;

[0025] 20 parts of the ethyl acetate extract of Ling vanilla is m...
