Description

Technical Field

[0002] Mites are tiny pests. Their corpses, secretions and excrement are all pathogenic allergens. They are distributed and breed in carpets, sofas, stuffed toys, bedding, cushions, mattresses and pillow cores. They feed on human sweat, secretions and shed dandruff and reproduce very quickly. Surveys show that about 97% of adults are infected with mites, mainly dust mites.

[0003] As people's living standards continue to improve, consumers have an increasingly strong demand for clothing mite removal and sterilization. Manufacturers have begun to develop detergents with sterilization and mite removal effects. During the research and development process, detergents must undergo mite removal experiments and issue test reports to clarify the mite removal effects of the detergents. However, there are currently no specialized experimental equipment, and most mite removal experiments are simple assembly device tests, which will lead to large errors in the experimental data. In addition, since the experimental water often contains live mites, the existing equipment does not have corresponding treatment measures, and direct discharge will cause environmental pollution.
