A food detection device suitable for culture tanks of cuvettes of various specifications

Abstract

The invention discloses a food detection device suitable for culture tanks of various specifications of cuvettes. The structure includes a culture tank, a body, an upper cover, a result printing device, a display screen, and control buttons. The culture tank is inlaid and fixedly mounted on the body On the end away from the display screen, the upper cover is installed on the end of the culture tank through a latch movable hinge. As a result, the printing device is installed and fixed on the top of the body and is parallel to the display screen. Below the display screen, compared with the prior art, the cuvette generates a downward force through the chassis pressing block against it, and the sliding rod moves downward in the sliding groove, and can be reset by the energy storage of the elastic element, so that the device can Test cuvettes of different specifications and heights at the same time, which improves the test efficiency of the device, avoids damage to cuvettes caused by forcibly closing the upper cover, and prevents the instrument from not working or even being damaged.

Description

technical field [0001] The invention belongs to the field of food detection, and in particular relates to a food detection device suitable for culture tanks of cuvettes of various specifications. Background technique [0002] In order to ensure people's dietary health and consumer rights, professional food inspection is essential. It mainly detects the general ingredients of food, trace elements, pesticide residues, mycotoxins, food additives and other harmful substances. In addition to traditional Smell, look, taste and other sensory tests, etc., will also use various instruments and devices to detect harmful substances. Such instruments are more accurate in detection and fast in analysis, and play a very important role in food testing, but the existing technology is insufficient. is: [0003] When the pesticide residue detector detects pesticide residues in food, usually the manufacturer will make the matching cuvettes into different specifications when producing the inst...

AI Technical Summary

Problems solved by technology

[0004] Aiming at the deficiencies in the prior art, the purpose of the present invention is to provide a food detection device suitable for the culture tanks of cuvettes of various specifications, so as to solve the problem that manufacturers usually produce when the pesticide residue detector detects pesticide residues in food. When using the instrument, the supporting cuvettes will be made into different specifications. When there are too many samples of the same type to be tested, the instrument can only distribute the samples according to a certain number of cuvettes of the same specification, resulting in a large number of tests. Improvement, in order not to affect the detection of the next sample, it is necessary to clean the comparison cuvette for detection times - 1 time, which reduces the detection efficiency. If the specification is ignored and the detection is performed directly, the upper cover cannot be closed, which will affect the detection results, and it must be closed forcibly It will cause damage to the cuvette, causing the buffer and sample solution inside to flow into the instrument, making the instrument unable to work, or even damaged.
