With the improvement of people's living standards and the improvement of the home environment, air conditioners and air purifiers have become more and more popular, and the airtightness of the living environment has been significantly improved. At the same time, the harmful substances in the air that are harmful to human health have also increased a lot, leading to the living room. The internal air quality is degraded. Although some air conditioners have a fresh air function, they can convect indoor and outdoor air. However, if the outdoor air is contaminated, the effect of this function on the indoor air quality will be greatly reduced.
One of the most important sources of influence on room air quality is microbial contaminants. Such as bacteria, viruses, and dust mites. In humid indoors, it is easy to breed fungi, causing microbes to pollute indoor air. In the process of mass reproduction, fungi also emit annoying special odor. These biological pollution can cause health damage to allergic diseases and respiratory diseases of home users. Therefore, it can be said that the focus of "family environmental protection" is to eliminate these sources of pollution, which not only guarantees the health of family members, but also reduces pollution to the external environment.
At present, in the air purification technology, the method for solving microbial contamination generally passes through: ultraviolet sterilization, heavy metal sterilization, biological sterilization, etc., but due to limitations of the use environment, these sterilization technologies have serious efficiency degradation, incomplete sterilization, secondary pollution, and the like. Disadvantages. At present, the negative ion technology commonly used in air conditioners only functions as a clean air, stimulating the nerves, breathing, and digestive system to make people feel comfortable, but it cannot be effectively sterilized.
Plasma refers to a state in which the number of positive ions and electrons are substantially the same and exists at a relatively large concentration. The cold plasma generator uses a high-voltage bipolar discharge to generate a large number of positive and negative ion groups, and releases positive and negative ions into the air. The two ions chemically react to form a strong oxidizing substance, resulting in bacterial structure change or energy conversion, and achieving sterilization. The principle of sterilization and purification is:
The cold plasma emitter ionizes the air under the action of a high voltage, and ionizes the water molecules in the air into positive ions formed by H+(H2O)n and negative ions formed by O2-(H2O)m. At the same time, the positive and negative ion groups are mixed in the space, surrounded by bacteria, and the positive and negative particle groups undergo the following chemical reaction to produce the active substance - hydroxyl radical (OH) or hydrogen peroxide (H2O2), and the active substance produced will have the molecular structure of the bacteria. Change or energy conversion for sterilization. Since the number of negative ions is larger than the number of positive ions during design, the remaining negative ions in the purification still float in the air, which can eliminate smoke, remove dust, eliminate odor, improve air quality, promote human blood circulation, and prevent air-conditioning diseases.
