Problems solved by technology

However, the traditional air extraction device has the following problems: 1. There is no elastic device at the mouth of the bag, which often causes the gas sample to leak from the mouth of the bag after the air collection is completed; 2. There is no outer bag, which makes it inconvenient to carry; 3. There is no sealing ring and card 4. The air taking device is integrated with the bag, which is inconvenient to disassemble and assemble as a whole

Description

technical field [0001] The invention relates to the field of gas collection bag devices, in particular to a portable gas collection bag. Background technique [0002] With the continuous development of society, my country's environmental pollution has deteriorated sharply. Among them, air pollution has become particularly prominent in recent years. In order to study the components in the polluted gas, it is necessary to take gas samples, and then carry out relevant detection and analysis on the gas. However, the traditional air extraction device has the following problems: 1. There is no elastic device at the mouth of the bag, which often causes the gas sample to leak from the mouth of the bag after the air collection is completed; 2. There is no outer bag, which makes it inconvenient to carry; 3. There is no sealing ring and card 4. The air taking device is integrated with the bag, which is inconvenient to disassemble and assemble as a whole. In view of the above problem...
