Pipetting device for food detection

Abstract

The invention discloses a pipetting device for food detection. The pipetting device includes a base, a fixing frame is arranged at the upper end of the base; a rotating device is arranged on one sideof the upper end of the fixed frame; a pipetting device is arranged at the lower end of the rotating device; a stock solution box is arranged below the pipetting device and is positioned at the upperend of the base; a detection box is arranged on one side of the stock solution box and located at the upper end of the base; wherein the rotating device comprises a support frame; furthermore, the support frame is positioned on one side of the fixed frame and is positioned at the upper end of the base; a movable shaft I is inserted into the upper end of the support frame; a motor I is arranged atone end of the movable shaft I; a movable ring is arranged on the movable shaft I and located between the fixed frame and the support frame. The outer side of the movable ring is sleeved with a fixedring; a first connecting rod is arranged on one side of the fixed ring, the end, away from the fixed ring, of the first connecting rod is movably connected with one end of a second connecting rod, theother end of the second connecting rod is connected with one side of the upper end of the fixed frame through a second movable shaft, and a third connecting rod is arranged at the end, away from thesecond connecting rod, of the second movable shaft and located on one side of the fixed frame.

Description

technical field [0001] The invention relates to the field of food detection, in particular to a pipetting device for food detection. Background technique [0002] At present, during food testing, it is sometimes necessary to add a food solution into a reaction test tube to react to detect food components, and sometimes the amount of food solution to be extracted is very high, very small, and needs to be precise. At this time, micro pipetting is required. The device is used to extract more precise volumes of food solutions, so that the detection is more reliable and the reaction is more complete. [0003] The existing ones have the following deficiencies and problems: [0004] (1) At present, many manually controlled pipettes on the market need to absorb and discharge the detection liquid by manual pressing, and long-term pressing operations may easily cause hand discomfort or injury; [0005] (2) It is necessary to manually bring the detection solution in the stock solutio...

AI Technical Summary

Problems solved by technology

[0004] (1) At present, many manually controlled pipettes on the market need to absorb and discharge the detection liquid by manual pressing, and long-term pressing operations may easily cause hand discomfort or injury;

[0005] (2) It is necessary to manually bring the detection solution in the stock solution box into the detection box. The manual operation is unstable, and dripping may occur during the pipetting process, resulting in inaccurate data
