Problems solved by technology

Filters of different materials have different resistance to allergens. In daily life, the filters are often cleaned and disinfected. Filters eroded by allergens cannot be used after simple cleaning and disinfection, but must be cleaned and disinfected. Replace with a new filter, but the resistance of the filter to allergens cannot be identified by naked eyes, so there is an urgent need for a method that can detect the anti-allergy of the filter, and choose a filter with higher anti-allergic for air purification equipment

Abstract

The invention discloses a method for detecting the anti-allergic properties of a filter, which is used to detect the anti-allergenic properties of the filter in an air purification device. It includes the following steps: S100: Cut the filter into a sample piece A with a diameter of 50 mm; S200: Sterilize sample A, sample B and sample C respectively; S300: Place sample A in a 250 ml sterile Erlenmeyer flask A. ; S400: Dye the dilution of the allergen solution on sample A and sample B; S500: Place sterile flask A, sterile flask B and sterile flask C in a space with an ambient temperature of 25 degrees Celsius. Let stand for 1 hour; S600: Add 10 ml of allergen extraction solution to sterile Erlenmeyer flask A, sterile Erlenmeyer flask B and sterile Erlenmeyer flask C respectively. The invention also provides a filter anti-allergy detection device. The present invention uses non-woven fabric as a comparison standard and can detect the anti-allergenicity of the sample filter compared with the non-woven fabric.

Description

technical field [0001] The invention relates to a filter screen anti-allergic detection method and device, belonging to the field of inspection and detection of household appliances. Background technique [0002] With the continuous deterioration of the environment, people pay more and more attention to the problem of air quality. For example, indoor air conditioners and air purifiers can improve air quality. Most of its principle of purifying the air is to filter the air through the filter to separate the impurities in the air. Therefore, the filter plays the role of separating impurities, which will lead to a large number of impurities attached to the filter. Lead to the breeding of a large number of allergens on the filter. Filters of different materials have different resistance to allergens. In daily life, the filters are often cleaned and disinfected. Filters eroded by allergens cannot be used after simple cleaning and disinfection, but must be cleaned and disinfected...
