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

Embodiment 1

[0033] Embodiment 1 of the present invention: a method for detecting anti-allergenicity of a filter, which is used to detect the anti-allergenicity of a filter in an air purification device, including the following steps:

[0034] S100: Cut the filter screen into sample A with a diameter of 50 mm; take two non-woven fabric samples with a diameter of 50 mm and record them as sample B and sample C;

[0035] S200: Sterilize sample A, sample B and sample C separately. If sample A can withstand high temperature and high pressure, sterilize at 121 degrees Celsius for 20 minutes; if sample A cannot tolerate high temperature and high pressure, rinse with sterile water for 11 minutes , Dry;

[0036] S300: Place sample A in a 250-ml sterile Erlenmeyer flask A, place sample B in a 250-ml sterile Erlenmeyer flask B, and place sample C in a 250-ml sterile Erlenmeyer flask C;

[0037] S400: Dip the diluent of the allergen solution on both sample A and sample B, and seal the mouth of the sterile Erl...

Embodiment 2

[0042] Embodiment 2: A method for detecting the anti-allergenicity of a filter, used to detect the anti-allergenicity of a filter in an air purification device, including the following steps:

Abstract

The invention discloses a filter screen antianaphylaxis detection method, which is used for detecting antianaphylaxis of a filter screen in an air purification apparatus. The method comprises the following steps: S100: cutting the filter screen into a sample sheet A with a diameter of 50 mm; S200: respectively sterilizing the sample sheet A, a sample sheet B and a sample sheet C; S300: placing the sample sheet A into a 250ml sterile triangular flask A; S400: respectively dropwise adding and dyeing a dilute solution of an allergen solution onto the sample sheet A and the sample sheet B; S500: standing the sterile triangular flask A, a sterile triangular flask B and a sterile triangular flask C in a space with an ambient temperature of 25 DEG C for one hour; and S600: respectively adding 10ml of allergen extract liquid into the sterile triangular flask A, the sterile triangular flask B and the sterile triangular flask C. The invention also provides a filter screen antianaphylaxis detection apparatus. A nonwoven fabric is used as a comparison reference, so that the antianaphylaxis of the sample filter screen and a comparison result with the nonwoven fabric can be detected.

Description

Technical field [0001] The invention relates to a method and a device for detecting anti-allergenicity of a filter screen, belonging to the field of household appliance inspection and detection. Background technique [0002] As the environment continues to deteriorate, air quality issues have attracted more and more attention. For example, indoor air conditioners and air purifiers have the effect of improving air quality. Most of the principle of air purification is to filter the air through a filter to separate impurities contained in the air. Therefore, the filter plays a role of impurity separation, which results in a large amount of impurities attached to the filter. Cause a large number of allergens to grow on the filter. Filters of different materials have different resistance to allergens. In daily life, filters are often cleaned and disinfected. Filters corroded by allergens cannot be used after simple cleaning and disinfection, but must be used. Replace with a new filt...
