Problems solved by technology

[0002] Now the air quality is getting worse and worse. PM2.5 is very serious in most cities. Masks have become a must-wear item for people to travel. Now there are all kinds of masks, but it is unknown how the filtering ability of the masks is. For mask manufacturers Or users need a device that can test the filtering ability of masks

Embodiment

[0018] When in use, turn on the switch 10 and the suction device 2 on one side starts to work. Air will flow in from the other side through the mask on the mask placement plate 3, measured by the PM2.5 sensor 4 on both sides of the mask placement plate 3 The data is stored in the storage device 5, and the processing device 6 calculates the average of the data on both sides to obtain the data difference, and displays it on the display screen 7. The data on the display screen 7 is stored in the storage device 5 again at the same time. When the display screen 7 is smaller, It is proved that the better the filtering ability of the mask is, when the data on the display screen 7 is larger, the prompt device 8 will automatically prompt.

Abstract

The invention belongs to the field of article detection and particularly relates to a device for detecting performances of filtration type masks. A PM 2.5 detection device is utilized for testing, PM 2.5 values before and after filtration through the masks are tested respectively, data differences are obtained, data is stored, the filtering capabilities of the masks are judged sequentially, and if the data difference is too large, the device makes a prompt automatically.

Description

Technical field [0001] The invention belongs to the field of article detection, and specifically is a device for detecting the performance of a filter mask. Background technique [0002] Now the air quality is getting worse and worse. PM2.5 is very serious in most cities. Masks have become a must-wear item for people when traveling. There are various kinds of masks, but the filtering ability of masks is unknown. For mask manufacturers Or users need a device that can test the filtering ability of masks. Summary of the invention [0003] In order to solve the shortcomings of the prior art, the present invention provides a device for detecting the performance of a filter mask. The present invention uses a PM2.5 detection device to test the PM2.5 value before and after the mask filter to obtain the data difference and store the data. , Judge the filtering ability of the mask in turn, if the data difference is too large, the device will automatically prompt. [0004] In order to achiev...
