Description

Technical Field

[0001] The utility model relates to the technical field of juice detection, in particular to a pre-treatment sampling device for juice sample detection. Background Art

[0002] Juice is a juice product obtained from fruits through physical methods such as squeezing, centrifugation, extraction, etc. It generally refers to pure juice or 100% juice. The produced juice needs to be sampled and tested. Pretreatment sampling devices are now mostly used to complete the sampling of juice. In actual use, it has the advantages of simple operation, stable sampling and good sampling effect.

[0003] The prior art discloses a juice sample detection pretreatment device with publication number: CN218629188U, comprising a sampling barrel, an anti-slip strip, a first thread, a sampling head, a connecting cover, a second thread, a sampling tube, a filtering groove, an oblique notch, a limiting cover, a third thread, a limiting ring, a push-pull assembly, a push rod, a piston head, a positioning groove, a pressing key, an anti-slip pattern and a spring. When in use, the sampling barrel needs to be held by hand, and then the pressing key is pressed with the thumb. As the pressing key is pressed, the piston head will move closer to the connecting cover, and then the sampling tube is inserted into the juice sample. Then, the pressing thumb is slowly loosened. At this time, the piston head will move upward under the action of elastic force, so that the juice will enter the interior of the sampling barrel through the sampling tube under the action of pressure, and then the sampling tube is inserted into the test tube used for detection. At this time, the pressing key is pressed again, and then the juice will be discharged through the filtering groove provided on the sampling tube under the action of pressure.

[0004] In the above utility model, the piston head moves up to draw the juice into the interior of the sampling cylinder through the sampling tube, but in this way, only one kind of juice can be sampled at a time. Since there are many kinds of juices, sampling multiple juices in sequence requires frequent movement of the sampling cylinder and pressing of the button, and the operation steps are cumbersome. At the same time, the juice contains impurities, which cannot pass through the filter groove, but will gather inside the sampling tube, which will eventually cause the sampling tube to be blocked and the sampling work to be terminated, reducing the practicality of the use of this utility model.

[0005] Currently, no effective solution has been proposed for the problems in the related technologies. Utility Model Content
