Description

Technical Field

[0002] The rapid development of industry also inevitably pollutes the environment. When detecting industrial exhaust gases, it is necessary to use a sampling device at the exhaust pipe port to sample the gas inside the exhaust pipe and collect it for detection;

[0003] Industrial emissions generate a large amount of high-temperature gas during industrial production, and the gas is mixed with a large amount of polluted particulate matter. When sampling, it is necessary to avoid the particulate matter inside the sampled gas clogging the air pump, or the high-temperature gas burning the user's hands holding the outer wall.

[0004] The inventor discovered the following problems in the prior art during the process of implementing the present invention:

[0005] 1) When sampling gas, particles are sucked into the device by traditional gas sampling devices. Due to the circulation of gas, particles will penetrate into the interior of the air pump, which will shorten the service life of the device and increase the cost of use for users.

[0006] 2) When the traditional gas sampling device samples high-temperature gas for a long time, a large amount of gas mixture will accumulate on its inner wall, which is difficult to clean. Therefore, the sealing structures at both ends of the device need to be replaced and cleaned in time.
