Description

Technical Field

[0001] The utility model belongs to the technical field of indoor waste gas collection, in particular to a waste gas collection device for indoor polluted space. Background Art

[0002] At present, exhaust gas from indoor polluted spaces is an increasingly prominent topic. After the exhaust gas from indoor polluted spaces is collected, it is necessary to test the gas discharged after purification. The quality of the test on the gas discharged after purification reflects whether the exhaust gas treatment device in the indoor polluted space meets the standards.

[0003] According to the description in the disclosed indoor polluted space waste gas collection device (authorization announcement number: CN215062666U), "the indoor polluted space waste gas collection device includes multiple collection heads located in different indoor spaces, one side of the collection head is connected to a pipe, and the pipes of the multiple collection heads are connected to the gas collecting chamber through a main collection pipe. A driving rod sliding left and right along the inner wall of the gas collecting chamber is provided in the gas collecting chamber, a one-way ventilation mechanism is provided in the main collection pipe, a mortgage rod is provided between the driving rod and the one-way ventilation mechanism, and a sliding buckle is provided on the one-way ventilation mechanism. The device itself has a non-return function, which can replace the check valve and will not cause high-hazard gases to flow back. When the driving rod slides to the left, the high-risk gas is inhaled and the one-way ventilation mechanism is closed. When the driving rod slides to the right, the high-risk gas is discharged and filtered, and the one-way ventilation mechanism is opened. The internal structure is not easy to be damaged. It can collect a large amount of hazardous waste gas, and the purified gas can be collected and discharged in a centralized manner. It can efficiently regulate the collection capacity of hazardous waste gas, and has great promotion value."

[0004] The existing device for collecting indoor exhaust gas cannot exhaust the air inside the collection bottle, causing the indoor air to mix with the air inside the collection bottle, resulting in errors in the detection results. It is also inconvenient to squeeze and fix the connecting head to prevent leakage. Therefore, a device for collecting exhaust gas from indoor polluted spaces is proposed to address the above problems. Utility Model Content
