Abstract

The invention relates to a testing device for dustproof property of canister, comprising an air flux control system, a respirator system, a canister fixing clamp, an air swirler and a timer. The air flux control system is used to control flux of air; the respirator system is used to simulate respiratory effect of human being; the canister fixing clamp is used to clamp the canister so as to finisha test; the air swirler is used to make the air passing through form vortex; and the timer is used to control time. The testing device can adjust simulated respiratory flux and respiratory frequency to test dustproof property of canister, and has advantages of small volume, environment friendly property and simple adjustable property.

Description

technical field [0001] The invention relates to a test device, in particular to a device for testing the dustproof performance of a canister. Background technique [0002] The canister is a device that removes dust and toxic and harmful substances in the air through physical adsorption and chemical reaction for human breathing. Usually canisters are used in conjunction with gas masks. Canisters are very important epidemic prevention and protective articles in social life, especially when catastrophes such as earthquakes, floods, and infectious diseases (such as SARS) are prevalent, it is very important. Since the canister is usually used in conjunction with the gas mask, the quality of the canister mainly depends on its dustproof performance, so it is very important to test the dustproof performance of the canister. In the dust-proof performance test of the canister, there must be a test device for the tester to complete the specified test under the specified conditions fo...
