Description

Technical Field

[0001] The utility model relates to the field of liquid detection, in particular to a liquid detector. Background Art

[0002] Currently, commonly used security inspection machines can only detect solid substances in packages. Current X-ray security inspection technology is unable to detect beverages, alcohol, oils, toxic and hazardous liquids, flammable and explosive liquids, etc. in packages. When staff find liquid-like substances in the package, they need to manually open the package for inspection, but manual inspection is also unable to fully distinguish dangerous liquids. A common practice is to ask the carrier to drink a sip of the suspicious liquid in front of them. This method is neither safe nor reduces security inspection efficiency.

[0003] With the continuous development of science and technology, liquid detectors have appeared on the market. However, current liquid detectors often hold the liquid container to be tested and stick the side wall of the liquid container to the detector probe. However, this method is difficult for inspectors to operate and has low detection efficiency. For example, when detecting the type of liquid in a metal container, a heated probe is often attached to the side wall of the container. Since the liquid on the side of the container is relatively dispersed, the liquid in the container takes a long time to be heated, which leads to a long time to detect a single sample. It is not suitable for places with high traffic flow, places with heavy detection tasks, or security inspections in public transportation such as airports and subways. Utility Model Content

The first detector 4 is primarily used to detect liquids contained in metal materials such as aluminum and iron cans.

At this time, the metal or non-metal container is placed at an angle in the container storage slot, and the liquid inside the tilted container accumulates at the bottom of the container. The bottom of the tilted container is directly close to the button 405 on the back panel 404. At this time, the button 405 is turned on and communicates with the central processing unit 11.

The detection result is compared with the memory and displayed on the display screen 2. The detection result can be printed through the detection information printing unit 5 as needed; the central processing unit 11 adopts but is not limited to the Intel-Core-2 Duo-CPUE7500 processor.

At the same time, the liquid in the container can be gathered at the bottom of the container, which is convenient for the first detector 4 or the second detector 3 to heat or microwave detect the liquid, thereby accelerating the heating rate of the liquid in the container and the microwave detection speed of the liquid, and improving the efficiency of liquid detection.
