The invention also discloses a preparation method of the air freshener; the air freshener can remove peculiar door,soothe the mood and improve sleep, can kill bacteria and viruses and resist bacteria and inflammation, has great antibacterial effect, can inhibit bacteria from growing and breeding in air and on thesurface of an object, has good safety and zero toxicity, has high efficiency and good environmental friendliness, is simple and good in safety, and is suitable for use in most places.

Description

technical field [0001] The invention relates to the technical field of daily chemical products, in particular to an air freshener. Background technique [0002] With the development of the country's economy, people's living environment is facing more and more problems. Air pollution, especially indoor air pollution, has become more and more serious, and people's health has also been greatly affected. In order to purify indoor air, many businesses have launched various types of air fresheners. But there are some problems in these fresheners in some respects: the one, the composition of some fresheners contains compositions such as ether, essence, itself is chemicals, just has aromatic smell, does not reach the purpose of purifying air, increases instead. The second is that the main purpose of some fresheners is to release fragrance and remove peculiar smell, but they cannot play the role of sterilization, calming and tranquilizing. [0003] Comparative document 1: The appli...
