Description

Technical Field

[0001] The invention relates to the technical field of security inspection, in particular to a liquid security inspection machine. Background Art

[0002] In current public places such as stations, liquid security inspections face multiple challenges. Traditional security inspection processes often only have one regular inspection channel, which has limited screening capabilities for liquid safety and lacks effective backup plans when equipment fails, resulting in reduced security inspection efficiency and increased potential safety risks. In particular, for the inspection of special-shaped bottled liquids, another sampling test is required, making it difficult to ensure full coverage.

[0003] In addition, for the detection of liquids in metal bottles, the existing technology mostly relies on the temperature measurement of the metal bottle body by contacting the temperature sensor set near the heating plate. This method has the problem of residual heat, which seriously affects the accuracy of subsequent detection and increases the risk of misjudgment and missed detection. Therefore, it has become an urgent problem to improve the intelligence and efficiency of liquid security inspection in public places such as stations and develop non-contact, high-precision detection technology. Summary of the invention

[0004] The purpose of the present invention is to provide a liquid security inspection machine to solve the above-mentioned shortcomings.

[0009] Furthermore, the detection component includes a microwave antenna, and the dielectric constant of the bottled liquid is detected by microwaves emitted by the microwave antenna to determine the type of the liquid.

[0010] Furthermore, the first detection slot and the second detection slot are arranged at an angle, and the angle between the first detection slot and the second detection slot and the horizontal plane is 0≤α≤70°, and the lower ends of the first detection slot and the second detection slot are provided with supporting surfaces perpendicular thereto.

[0011] Furthermore, a through hole is provided in the area of ​​the flexible carrier directly above the temperature sensor, and the temperature sensor detects the temperature change of the liquid container on the flexible carrier through the first through hole.

[0012] The setting of the through hole enables the temperature sensor to measure the temperature of the liquid container through the through hole, realizing non-contact temperature measurement, and effectively avoiding the influence of heat residue caused by contact temperature measurement on the authenticity of subsequent detection results.

[0013] Furthermore, the temperature increasing device is a heating wire arranged in a concave shape on the flexible carrier, and the through hole is located in the middle of the concave heating wire.

[0014] Compared with the prior art, the present invention has the following beneficial effects: the present invention can directly detect liquids in single-layer non-metallic bottles and liquids in metal bottles, as well as sample detection of liquids in special-shaped bottles and liquids in double-layer thermos bottles by setting conventional detection areas, unconventional detection areas and metal detection areas, and the unconventional detection area can also be used for detection of liquids in special-shaped bottles after they are inverted (the bottle cap contacts the unconventional detection area). In addition, the unconventional detection area can also serve as a backup for the conventional detection area. When the conventional detection area cannot work normally, the sampled liquid can be detected by the unconventional detection area after sampling. BRIEF DESCRIPTION OF THE DRAWINGS
