Mask filtering performance tester

Abstract

The invention relates to a mask filtering performance tester which consists of a vacuum air pump, a flowmeter, a particle counter, a test pipeline and a base, wherein the vacuum air pump is connected with the flowmeter by a PVC steel wire hose with aperture of 30mm; the test pipeline is connected with the particle counter and the flowmeter through a PU fine hose with aperture of 12mm respectively. The mask filtering performance tester provided by the invention has the advantages of small volume, light weight, low cost and easiness in carrying, can test the filtering efficiency of a mask in different particulate matter concentration and replace the large and expensive TSI-8130 tester in daily detection, and can obviously improve the test efficiency and lower the test cost.

Description

technical field [0001] The invention relates to a filter material performance tester, in particular to a mask filter performance tester. Background technique [0002] In recent years, the smog phenomenon has become more and more serious, and masks have become a necessary means for people to protect themselves from external hazards. However, there are various types of masks on the market at present, and which masks have a better protective effect has become a common concern of consumers and relevant scholars, and the mask filtration performance testing device has also received people's attention. In order to study the filtration performance of medical masks, industrial dust masks and other filter materials, researchers have invested in the development of material filterability testing devices as early as the 20th century. Various types of filtration performance testing devices have appeared at home and abroad. . The JIS detection system developed in Japan evaluates the ch...

Problems solved by technology

Most of these devices are large-scale equipment used in medical institutions and laboratories. They are large in size and expensive. Only a few testing institutions and enterprises purchase and use them, and are not suitable for small laboratories, rapid response institutions and ordinary consumers.

Since masks are greatly affected by the environment, it is quite inconvenient to use large-scale equipment during outdoor monitoring or mobile measurement in different indoor spaces. Therefore, the market urgently needs to develop a small, light, and easy-to-carry mask filtration performance testing device.
