[0002] In the process of environmental management, the quality of air is usually monitored, and in the process of detecting air quality, gas collection device is needed to sample and detect the gas in the air.
[0003] The Chinese patent with publication number CN220525441U discloses a gas sample collection device, which is provided with a lifting column on the fixed column, and a gas pump is installed at the top end of the lifting column, a collection bottle is clamped on the combined frame, air pipes are arranged at both ends of the collection bottle, sealing caps are threadedly arranged in cooperation with the air pipes, and a sealing plug is arranged in the collection bottle, so that the inside can be bidirectionally disassembled and used during use.
[0004] The above-mentioned device can only collect the gas in one direction at the same time during use, which means that if we need to detect the gas content at different heights or directions in actual operation, we must sample step by step and in different time periods. Since the gas content at different heights and directions often differs significantly at the same time, these differences themselves have important detection value. If synchronous sample collection cannot be achieved, the time difference between the front and rear collection may cause air flow, and thus the collected sample data may not be uniform. This inconsistency of data will undoubtedly have a serious impact on subsequent environmental gas detection and judgment, and may even mislead the detection results, thereby reducing the accuracy and reliability of the detection to some extent, which needs to be optimized and improved.
