家用除螨仪性能测试与分析研究

Performance test and analysis of home mite control instrument

抽取市场在售不同价位与类型的27台家用除螨仪,调查除螨仪的基本参数及特点,测试除螨仪的功率、噪声、软表面除尘性能、除螨性能以及除菌性能,分析除螨仪性能的影响因素与相关性,防止除螨仪行业的不合规情况发生,保证除螨仪领域的安全可靠性并对家庭购买除螨仪提供参考与指导。经测试,27台样机噪声全部符合要求,噪声与实测功率具有正向显著相关性(rs=0.642**,P=<0.001),实测功率越大样机噪声越大。软表面除尘测试中仅有6台软表面除尘率超过90%,占全部样机的22.22%。除螨性能测试中有2台样机低于限定值,样机除螨能力与除尘能力低度正向相关(rs=0.480*,P=0.011)。除菌性能测试中样机除菌效果合格率为88.9%,大肠埃希氏菌相较于金黄色葡萄球菌更易被去除,去除效果更好。根据抽查结果来看,除螨仪行业的样品质量基本处于良好层级,但仍有不合格产品出现,不合格产品的生产企业应加强社会责任感,按标准要求提高产品质量。

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.
