Description

This utility model relates to the technical field of air detection, and specifically to an air detection sampling device.

Conventional technology

As people's living standards become higher, the demand for air mass becomes stricter and the measurement of air mass becomes stricter. Accordingly, air mass detectors have been proposed. Sampling devices are an important component in air mass detectors. The manufacturing process of the conventional air detection sampling device is becoming more and more perfect day by day, but there is still room for improvement.

The conventional techniques have the following problems.
For example, the conventional air detection and sampling apparatus disclosed in Patent Document 1 is heavy, but has no moving means, so the degree of movement difficulty of the apparatus is large. A few sampling devices with rollers that allow movement are suggested, but the rollers are subject to pressure due to the weight of the sampling device over a long period of time, thus reducing the normal service life of the rollers.
