Abstract

The invention discloses a Chinese chestnut flower mosquito killing air freshener, which contains Chinese chestnut flower extracting solution, alcohol and distilled water. The method comprises the steps of: A) evenly mixing Chinese chestnut flower with distilled water into a distilling kettle with a weight ratio of 1: 2-8, B) starting an electric boiler, slowly opening a control valve after the pressure in boiler reaches to 0.05MPa so as to guide the steam into the distilling kettle, heating the steam in the distilling kettle, regulating a steam valve after the temperature of the kettle reaches to 90 to 100 DEG C, keeping the steam pressure in the distilling kettle between 0.01 and 0.07 MPa, opening a cooling water valve of a condensation collector, collecting the condensed solution so as to obtain the rough product of Chinese chestnut flower, C) solving 0.01 to 0.05 % of preservative in 40 to 60 % of absolute ethyl alcohol, adding 5 to 20 % of the rough product of Chinese chestnut flower obtained from step B), 0.2 to 0.7 % of menthol crystal, and water to obtain the Chinese chestnut flower mosquito killing air freshener. The Chinese chestnut flower mosquito killing air freshener of the invention is prepared from the extracting solution of the natural Chinese chestnut flower, the cost is low, the mosquito killing effect is excellent, the smell is fresh, the freshener is harmless to human body and the preparation process is simple, mild and environment-friendly.

Description

Technical field [0001] The invention relates to a chestnut flower mosquito repellent air freshener prepared by using natural chestnut flower extracts, belonging to the technical field of comprehensive utilization of agricultural and forestry products; the invention also relates to a preparation method of the chestnut flower mosquito repellent air freshener. Background technique [0002] In order to avoid mosquitoes, mosquito coils produced with pyrethrum as raw materials are commonly used. However, relevant tests have confirmed that they have obvious damage to the human nervous system and hematopoietic system. Be careful when using them. [0003] At present, many plant essential oils have been found to have a certain mosquito repellent effect. Chinese patent 200910154435.0 discloses the application of torreya essential oil in mosquito repellent; Chinese patent 200610042582.5 discloses a plant essential oil air disinfectant and freshener, which is based on tea tree, eucalyptus, pine...
