[0003] In current gasoline sample detection, gasoline sampling is directly taken by a glass container, or a measuring cylinder or a liquid volume measuring container is used. The problem is that each measurement is not accurate enough, and the gasoline adhered to the wall surface during sample pouring is easy to contaminate the laboratory. The volatility of gasoline can also cause harm to the laboratory personnel.

[0004] The prior art discloses a patent with publication number CN216669400U to solve the above-mentioned technical problems. The technical solution disclosed in the patent document is as follows: a new laboratory gasoline automatic sampling equipment, which comprises an explosion-proof shell, a liquid inlet pipe, a liquid outlet pipe, a single-chip microcomputer and a small peristaltic pump. The single-chip microcomputer and the small peristaltic pump are located in the explosion-proof shell. The liquid inlet pipe passes through the explosion-proof shell and is connected to the liquid inlet of the small peristaltic pump. The liquid outlet pipe passes through the explosion-proof shell and is connected to the liquid outlet of the small peristaltic pump. The small peristaltic pump is connected to the single-chip microcomputer. The new laboratory gasoline automatic sampling equipment solves the shortcomings of manual sampling, has a simple structure, is convenient to use, and has a high degree of automation. It especially solves the series of tedious processes of laboratory sampling, is convenient and fast, and is easy to operate.
