Due to the small size of the car, the slight smell emitted by each component will cause serious odor inside the car. It is difficult to achieve the purpose of fresh smell in the car only by controlling raw materials, and certain post-processing methods are needed.
The existing commonly used means of purifying air mainly use photocatalyst, activated carbon, air freshener, etc. Photocatalyst is a general term for photo-semiconductor materials with photocatalytic function represented by nano-scale titanium dioxide. One of the most ideal materials, but the photocatalyst is suitable for the removal of low-concentration pollutants, and it is powerless for high-concentration pollutants, and it cannot remove odors; activated carbon is not affected by the concentration of pollutants and has the characteristics of fast adsorption, but it is easy to adsorb and saturate , need to be repeatedly consumed; car air fresheners, also known as "environmental perfume", are a common method for daily treatment of car odors. Due to their portability, ease of use, and low price, air fresheners have become the first choice for dealing with car odors. However, it has two major flaws. One is that it cannot decompose and effectively reduce VOC, but only "covers" the odor by confusing people's sense of smell.
The other is that while it "covers up" the peculiar smell, it also introduces a new source of pollution. The chemical components such as organic solvents and artificial flavors contained in it may cause greater harm to the human body.
Long-term use will have extremely adverse effects on the human body, and its duration is generally only about 3 days, requiring repeated consumption, and the economy is poor

Description
technical field [0001] The invention relates to the field of air purification, in particular to a deodorizing and purifying liquid for air in a car. Background technique [0002] Cars have become one of the commonly used tools for modern travel. When a new car comes off the assembly line, there is usually a strong mixed smell in the car, which can easily cause dizziness, headaches and other reactions among the occupants in the car, and can induce various diseases. [0003] In response to the problem of odor in the car, the method generally adopted by car companies is to control raw materials. Due to the small size of the car, the slight smell emitted by various parts will cause serious odor inside the car. It is difficult to achieve the purpose of fresh smell in the car only by controlling raw materials, and certain post-processing methods are also needed. The existing commonly used means of purifying air mainly use photocatalyst, activated carbon, air freshener, etc. Photo...
