Problems solved by technology

Although the above measures can reduce the number of mites and mite allergens in dust, the effect is not obvious, and the symptoms of allergic patients cannot be significantly alleviated, and it is easy to affect people's normal life
[0004] Therefore, there is still the problem that the prior art cannot effectively control the mites and their allergens in the indoor environment

Embodiment 1

[0012] Example 1 The killing effect of an air purifier equipped with an electric field generating device on indoor dust mites was tested.

[0013] Adult dust mites were taken to be treated with air purifiers at different times (12h, 24h, 36h, 48h, 60h, 72h, 84h). The electric field generated by the electric field generator was 80KV / cm, and the number of dust mites in each time group was 200. After the treatment, the dead number of D. farinae was observed under an anatomical microscope and the acaricidal rate was calculated. Acaricidal rate (%) = number of dead mites in each group / total number of dust mites in each group.

[0014] It can be seen from Table 1 that when the electric field generator is turned on (80KV / cm), after the air purifier acts for 84 hours, the acaricide rate reaches 100±1%. The effect is very limited, the rate of killing mites for 84 hours is only 29±4%; in the case of the blank control (that is, without the air purifier), the natural death rate of mites...

Embodiment 2

[0016] Example 2 The air purifier equipped with an electric field generating device is tested for its removal effect on indoor dust mite allergens.

[0017] Randomly select 20 student dormitories of Shenzhen University, each dormitory adopts the following 4 conditions of A, B, C and D for air dust sampling: A represents sampling in natural state; B represents sampling with air conditioner turned on; C represents air conditioner and Sampling when the air purifiers with electric field generating devices are turned on at the same time; D represents sampling when only the air purifiers equipped with electric field generating devices are turned on. The sampling tool is BCF-300 microcomputer dust sampler, with an air flow rate of 15L / min, placed in the center of the bedroom, 1-1.5m above the ground, with a glass fiber membrane (pore size 0.3μm) installed on the dust sampler to trap air dust particles in. Collect the glass fiber membrane on the sampler after each sampling, and mar...

Abstract

The invention provides a method for controlling mites in indoor environment. The method for controlling mites in the indoor environment is characterized in that an electric field generator is installed in an air purifier. The air purifier is opened, an electric field generated by the electric field generator is 5-80KV / cm, and action time is 12-84 hours. The method for controlling mites in the indoor environment can purify the air, simultaneously can effectively kill the mites and eliminate mite allergen, controls the mites in the indoor environment, avoids secondary pollution of the mite allergen, is capable of eliminating influence of the mites on allergy patients, and cannot influence normal life of people.

Description

technical field [0001] The invention relates to purification of indoor environment, in particular to a method for controlling mite in indoor environment. Background technique [0002] Allergic diseases are considered by the World Health Organization (WHO) to be one of the three major diseases that should be prevented and controlled in the 21st century. Such diseases include allergic asthma, allergic rhinitis, allergic dermatitis, etc., which are common and frequently-occurring diseases in clinical practice. Scholars in Europe, America, Asia and other regions have confirmed that dust mites are the most important allergens in patients with allergic diseases. Among the many allergens introduced to allergic diseases, the positive rate of dust mites is as high as 70-80%. Acarids are small arthropods. There are about 50,000 species of mites known in nature, of which more than 30 species are related to human allergic diseases. House dust mite and dust mite are the dominant species...
