Performance test and analysis of home mite control instrument
Extract 27 household mite removal devices of different prices and types from the market,investigate the basic parameters and characteristics of mite removal devices,test the power,noise,soft surface dust removal performance,mite removal performance,and sterilization performance of mite removal devices,analyze the influencing factors and correlations of mite removal device performance,prevent non compliant situations in the mite removal device industry,ensure the safety and reliability of mite removal devices,and provide reference and guidance for households to purchase mite removal devices.After testing,the noise of all 27 prototypes meets the requirements,and the noise has a significant positive correlation with the measured power(rs=0.642**,P=＜0.001).The larger the measured power,the greater the noise of the prototype.In the soft surface dust removal test,only 6 machines had a dust removal rate exceeding 90%,accounting for 22.22%of all prototypes.In the mite removal performance test,two prototypes were below the limit value.The mite removal ability and dust removal ability of the prototypes were significantly correlated(rs=0.480*,P=0.011),and there was a low positive correlation between mite removal ability and dust removal ability.In the sterilization performance test,the qualified rate of the prototype's sterilization effect is 88.9%.Escherichia coli is easier to remove compared to Staphylococcus aureus,and the removal effect is better.According to the spot check results,the sample quality of the mite removal instrument industry is basically at a good level,but there are still unqualified products.The production enterprises of unqualified products should strengthen their sense of responsibility and improve product quality according to standard requirements.
