Embodiment

[0088] Such as Figure 1-Figure 2 As shown, the detection device of the barrier performance of the mask of the present embodiment includes a gas supply cavity 1 for providing haze gas, a detection cavity 13 for detecting the barrier performance of the mask, an exhaust pipe 23, and a connecting pipe 27 connected in sequence And air quality detector 26;

[0089] The air supply chamber 1 is provided with a horizontal piston assembly, which includes an integrally formed piston head 6 and a piston rod 7; the two ends of the air supply chamber 1 are respectively provided with a first baffle 10 and a The second baffle 12; the first baffle 10 is provided with an air outlet 11 and a hole for the piston rod 7 to pass through; the wall of the air supply cavity 1 is provided with an air inlet; the The air inlet is provided with a first valve 8 for sealing or opening the air inlet and opening to the side of the air supply cavity 1;

[0090] The gas supply chamber 1 communicates with the ...

experiment example

[0128] Take 7 kinds of commercially available masks, adopt the mask barrier performance detection device of the present invention, and carry out the detection of mask barrier performance, and the specific data are shown in Table 1.

[0129] Table 1 mask detection device of the present invention is to the detection result of 7 kinds of commercially available masks

[0130]

[0131] It can be seen that the detection device of the barrier performance of the mask of the present invention can accurately detect the anti-haze effect of different varieties and different types of masks, and is accurate and effective for PM2.5 and PM1.0, and can truly reflect the anti-haze effect. Guide manufacturers to test and upgrade mask technology, improve the anti-haze performance and quality of masks, and benefit the public. At the same time, it also guides consumers to choose masks with anti-smog function, focusing on the optimal use of anti-smog effect, which is beneficial to physical and me...

Abstract

The invention discloses a detection device of obstructing performance of a mask and a detection method of the detection device and belongs to the technical field of detection instruments. The detection device of the obstructing performance of the mask comprises a gas supply cavity for supplying haze gas, a detection cavity for detecting the obstructing performance of the mask, a tail gas pipe, a connecting pipe and an air quality detector, which are communicated in sequence. The invention further discloses the detection method of the obstructing performance of the mask by utilizing the detection device of the obstructing performance of the mask. The detection device disclosed by the invention is small in volume, low in cost, simple in structure, convenient to move and simple and convenientto operate, can be used for effectively detecting the obstructing efficiency of the mask on small particles and can meet the requirements of common consumers, so that the quality inspection department and the consumers can rapidly, simply and conveniently identify the good and poor quality of the mask.

Description

technical field [0001] The invention relates to a detection device for the barrier performance of a mask and a detection method thereof, belonging to the technical field of detection instruments. Background technique [0002] With the continuous improvement of the level of industrialization, industrial and other vehicle exhaust and other exhaust gases are continuously discharged, and the air quality problem is becoming more and more serious, which seriously affects people's health. Masks have become a must-have item for most people. At present, there are various masks on the market, and it is difficult for consumers to distinguish their pros and cons. In order to allow consumers to choose masks with excellent barrier performance, a detection device for the barrier performance of masks is needed, which can detect the barrier performance of masks to small particles such as PM2.5. [0003] As early as the 20th century, researchers have invested in the development of mask barri...
