Description

Technical Field

[0001] The utility model mainly relates to the field of food detection, and in particular to a sampling device used for food detection. Background Art

[0002] The indicators of food testing mainly include general food component analysis, trace element analysis, pesticide residue analysis, veterinary drug residue analysis, mycotoxin analysis, food additive analysis and analysis of other harmful substances, etc. According to the characteristics of the items being tested, the test of each indicator corresponds to the corresponding test method;

[0003] In addition to traditional routine analysis methods, instrumental analysis methods have gradually become the main means of food hygiene inspection, including spectrophotometry, atomic fluorescence spectroscopy, electrochemical method, atomic absorption spectroscopy, gas chromatography, high performance liquid chromatography, etc. The above inspection methods can be roughly divided into inorganic component analysis methods and organic component analysis methods according to the inspection items;

[0004] When sampling food, an extraction device is needed to extract the food in the sampling cup into the interior of the sampling device for transportation.

[0005] The inventor discovered the following defects during the operation of the specific embodiment:

[0006] In the process of sampling food, a glass dropper is generally used to sample food samples. However, after each sampling, the amount drawn into the glass dropper cannot be controlled, and the food needs to be repeatedly drawn, which makes the operation of sampling food samples more cumbersome.

[0007] It should be noted that the above contents belong to the technical cognition scope of the inventor. Since the technical contents in this field are vast and too complicated, the above contents of this application do not necessarily constitute prior art. Utility Model Content

[0009] The utility model provides a sampling device for food detection, which is used to solve the technical problems existing in the above-mentioned background technology.

[0010] 2. Technical solution:

[0011] To achieve the above-mentioned purpose, the technical solution provided by the utility model is: a sampling device for food testing, comprising a sampling shell, a sample storage groove is opened inside the sampling shell, a fixing ring is arranged in the middle of the outer wall of the sampling shell, a spring telescopic rod is arranged on the top of the fixing ring, a top cover is arranged on the top of the spring telescopic rod, a connecting shaft is arranged on the bottom of the top cover, a sliding plate is arranged on the bottom of the connecting shaft, and the sliding plate is slidably connected to the inner wall of the sample storage groove.

[0012] Furthermore, the number of the spring telescopic rods is set to be multiple, and the multiple spring telescopic rods are arranged in a circular array on the top of the fixing ring.

[0013] Furthermore, a fitting cover is provided on the outer wall of the sampling shell, a sliding hole is provided in the middle of the fitting cover, the fitting cover is slidably connected to the sampling shell through the sliding hole, and air holes are provided on both sides of the top of the fitting cover.

[0014] Furthermore, a threaded tube is provided at the bottom of the sampling shell, a filtering structure is provided on the outer wall of the sampling shell, and the sampling shell and the filtering structure are connected via the threaded tube.

[0015] Furthermore, the filtering structure includes a mounting tube, the inner wall of the mounting tube is connected to the outer wall of the threaded tube, and a sampling port is provided directly below the mounting tube.

[0016] Furthermore, a feed trough is provided inside the sampling port, the feed trough is connected to the sampling shell, and a filter baffle is provided on the inner wall of the feed trough.

[0017] 3. Beneficial effects:

[0018] Compared with the prior art, the technical solution provided by the utility model has the following beneficial effects:

[0019] The utility model can control the amount of food sample drawn into the sample storage tank by means of the spring telescopic rod. The top cover is pushed downward according to the amount to be drawn, so that the top cover presses the spring telescopic rod, and the top cover drives the sliding plate to move downward through the connecting shaft, and then the filtering structure is inserted into the food sample. After the top cover is released, the spring telescopic rod pushes the top cover to reset, so that the top cover drives the sliding plate to move upward, thereby drawing the food sample into the sample storage tank. The sliding plate moves to different positions to draw different amounts of food samples.

[0020] Insert the filtering structure into the middle of the food sample and shake the cup containing the food sample to prevent large particles from adhering to the surface of the filter baffle. Then, before the food sample enters the sample storage tank, the large particles in the food sample will first be filtered out by the filter baffle. The filter baffle is snap-connected to the feed tank and can be removed when it is not needed. BRIEF DESCRIPTION OF THE DRAWINGS
