[0002] Gasoline is a volatile, flammable hydrocarbon mixture liquid obtained by fractionation and cracking of petroleum, and can be used as fuel. It is a transparent liquid, flammable, and has a distillation range of 30°C to 220°C. Its main components are C5-C12 aliphatic hydrocarbons and cycloalkanes, as well as a certain amount of aromatic hydrocarbons. Gasoline has a high octane number. Since gasoline has many components, it is necessary to sample and test it.

[0003] After searching, the utility model patent with patent number CN219369745U discloses "a gasoline oil sample detection device". The gasoline oil sample detection device is equipped with a reciprocating component inside. When testing the gasoline, the gasoline to be tested is added into the detection tank through the oil filling pipe. Before the test, the drive motor is turned on first, and the drive motor drives the reciprocating screw to rotate, driving the stirring blade to rotate, and performing preliminary stirring treatment on the gasoline to improve the fluidity of the gasoline. During this process, the reciprocating screw can drive the reciprocating component on it to move up and down. During this process, the cleaning plug of the reciprocating component can simultaneously scrape and clean the inner wall of the oil filling pipe, so that the oil impurities hanging on the inner wall of the oil filling pipe can be scraped off to avoid the long-term solidification of oil impurities, thereby ensuring the accuracy of subsequent oil detection.

[0004] When the device is used, it needs to be manually injected with material through the oil injection pipe, which is troublesome and inconvenient to use.

[0005] Therefore, it is necessary to provide a gasoline sample detection device to solve the above technical problems. Utility Model Content
