[0002] Food is something that everyone must eat every day. Therefore, in order to ensure that people can eat healthy and safe food, it is necessary to test the pesticide residues on the food.

[0003] When extracting samples, the residue on the surface of the food will fall into the sample pool, causing impurities to float on the surface and inside of the sample, thus affecting the detection work. Therefore, the extracted samples need to be filtered and purified for a second time to improve the detection accuracy. The traditional extraction method uses a manual filter extraction tube for extraction, and during the extraction process, a large pressure is required to insert the extraction tube into the filter tube, and in order to compare and detect accuracy, multiple extractions are required, which results in each extraction being a separate operation, which is time-consuming, labor-intensive and troublesome.

[0004] Therefore, how to provide a sample filtration auxiliary device for pesticide residue detection is a problem that those skilled in the art need to solve urgently. Utility Model Content

It should be understood that the specific embodiments described herein are only used to explain the present utility model and are not used to limit the present utility model.

[0027] The following describes the specific implementation of the present utility model in detail with reference to specific embodiments.

[0028] As Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 and Figure 5 shown, a schematic structural view of an auxiliary device for filtering samples for pesticide residue detection provided by an embodiment of the present utility model includes;

[0029] Containing box 1;

[0030] Top plate 2, the top plate 2 is movably clamped on the top of the containing box 1;

[0031] Vertical sampling structure, the vertical sampling structure is arranged on the top plate 2;

[0032] Filtering tube 4 and sampling tube 5, the filtering tube 4 and the sampling tube 5 are arranged in an array from top to bottom on the vertical sampling structure.

[0033] In the embodiment of the present utility model, when in use, the filter tube 4 and the sampling tube 5 are installed on the vertical sampling structure, and then inserted into the storage box 1 for sampling;

[0034] By setting the vertical sampling structure, when in use, sampling of multiple sampling tubes can be carried out at one time, and when pressing down, the force is evenly distributed, reducing the pressure generated during pressing, so that the sampling speed is improved.

[0035] Such as Figure 1 、 Figure 2 and Figure 4 As shown, as a preferred embodiment of the present utility model, a pre-filtering structure is further provided on the left side of the storage box 1. The pre-filtering structure includes a filter box 12, an arc-shaped filter plate 16 and a water leakage groove 17. The filter box 12 is fixedly installed on the left side of the storage box 1. A residue box 13 is movably inserted at the bottom of the outer end of the filter box 12. The water leakage grooves 17 are arranged in an array inside the residue box 13 and are communicated with the inside of the storage box 1. The arc-shaped filter plate 16 is fixedly installed in the middle of the filter box 12, and openings are symmetrically preset on the outer sides of the front and rear ends.

[0036] In the embodiment of the present utility model, when in use, the sample is poured into or discharged into the filter box 12 on the surface of the storage box 1, and then along the arc-shaped filter plate 16 inside the filter box 12, so as to remove the large-particle impurities contained therein, and under the impact of the liquid, it falls into the residue box 13 through the preset openings;

[0037] By setting the water leakage grooves 17, the sample entering the residue box 13 will flow back into the storage box 1 through the water leakage grooves 17 communicated with the storage box 1, avoiding a large amount of samples from accumulating in the residue box 13 and causing waste.

[0038] Such as Figure 1 、 Figure 2 、 Figure 3 and Figure 4 As shown, as a preferred embodiment of the present utility model, the vertical sampling structure includes a mounting rubber block 6 and a pressing plate 7. Placement rings 3 are arranged in an array on the surface of the top plate 2. The filter tube 4 is movably inserted in the middle of the placement ring 3. The sampling tube 5 is movably arranged inside the filter tube 4. The mounting rubber block 6 is movably inserted at the top of the sampling tube 5. The pressing plate 7 is fixedly installed on the top of the mounting rubber block 6. A handle 8 is fixedly installed on the top of the pressing plate 7. Positioning columns 9 are arranged in an array on the left and right sides of the surface of the top plate 2. Insertion rods 10 are arranged in an array at the bottom of the left and right sides of the pressing plate 7 and are movably inserted into the positioning columns 9.

[0039] In the embodiment of the present utility model, when in use, the sampling tube 5 is successively installed on the mounting rubber block 6. Subsequently, the insertion rod 10 at the bottom of the pressing plate 7 is aligned with the positioning column 9 on the surface of the top plate 2. Then, the pressing plate 7 is pressed downward through the handle 8, so that the sampling tube 5 can be quickly and accurately inserted into the filter tube 4 preset on the surface of the pressing plate 7, thereby extracting the internal sample.

[0040] By setting the vertical sampling structure, the sampling work of multiple sampling tubes 5 can be carried out at one time, thus changing the traditional sampling work that requires manual sampling one by one, resulting in a cumbersome process.

[0041] As Figure 1 and Figure 3 shown, as a preferred embodiment of the present utility model, a ventilation hole 11 is provided in the middle of the mounting rubber block 6 and penetrates through the surface of the pressing plate 7, so that the sampling tube 5 is communicated with the outside.

[0042] In the embodiment of the present utility model, when in use, by providing a ventilation hole 11 in the middle of the mounting rubber block 6 and penetrating through the surface of the pressing plate 7, the sampling tube 5 is communicated with the outside, which facilitates the entry of the sample into the sampling tube 5 and avoids the generation of pressure, thus facilitating sampling.

[0043] As Figure 3 and Figure 5 shown, as a preferred embodiment of the present utility model, a filter hole 18 is provided at the bottom of the filter tube 4, a through hole 19 is provided at the bottom of the sampling tube 5, a cross support rod 20 is fixedly installed in the middle of the through hole 19, a limit plug 21 is movably inserted in the middle of the cross support rod 20, and a rubber plug 22 is fixedly installed at the top of the limit plug 21.

[0044] In the embodiment of the present utility model, when in use, by providing a filter hole 18 at the bottom of the filter tube 4, the secondary filtration of the entering sample is facilitated, further improving the purity of the sample. At the same time, by setting the rubber plug 22 and the limit plug 21, their heights are changed with the height and the impact of the sample, facilitating the entry of the sample and reducing the pressure required for sampling.

[0045] As Figure 3 and Figure 5 shown, as a preferred embodiment of the present utility model, the diameter value of the rubber plug 22 is equal to the diameter value of the filter hole 18, and the diameter value of the rubber plug 22 is smaller than the diameter value of the sampling tube 5.

[0046] In the embodiment of the present utility model, when in use, by making the diameter value of the rubber plug 22 equal to the diameter value of the filter hole 18, the blocking is facilitated, and by making the diameter value of the rubber plug 22 smaller than the diameter value of the sampling tube 5, the upward movement is facilitated, allowing the sample to enter.

[0047] As Figure 1 and Figure 2 shown, as a preferred embodiment of the present utility model, a filling port 15 is fixedly installed at the top of the filter box 12, and a on-off valve 14 is movably installed on the surface of the filling port 15.

[0048] In the embodiment of the present utility model, when in use, by fixedly installing a filling port 15 at the top of the filter box 12 and movably installing a on-off valve 14 on the surface of the filling port 15, it is convenient to control the entry and exit of the sample in the holding box 1.

[0049] In the above embodiment of the present utility model, a pesticide residue detection sample filtering auxiliary device is provided. When in use, open the on-off valve 14, and then pour or discharge the previous sample into the filter box 12 on the surface of the holding box 1 through the filling port 15. Then, along the arc-shaped filter plate 16 inside the filter box 12, large-particle impurities contained therein are removed, and under the impact of the liquid, they fall into the residue box 13 through a preset opening. The sample that enters the residue box 13 will flow back to the holding box 1 through the water leakage groove 17 connected to the holding box 1, avoiding a large amount of sample accumulation in the residue box 13 and causing waste;

[0050] Subsequently, the sampling tube 5 is successively installed on the installation rubber block 6. Then, align the insertion rod 10 at the bottom of the pressing plate 7 with the positioning column 9 on the surface of the top plate 2, and then press down the pressing plate 7 through the handle 8, so that the sampling tube 5 is quickly and accurately inserted into the filter tube 4 preset on the surface of the pressing plate 7, thereby extracting the sample inside;

[0051] When sampling, the sample in the holding box 1 will, under the action of the filter holes 18 at the bottom of the filter tube 4, filter out small-particle impurities therein, so that a relatively clean sample enters the filter tube 4. Subsequently, when the sampling tube 5 enters the filter tube 4 and contacts the sample, the rubber plug 22 in the through hole 19 at its bottom will drive the limit plug 21 to move along the cross-shaped support rod 20 due to the impact of the sample, so that the sample enters the sampling tube 5. When the sampling tube 5 is taken out, the liquid will press on the rubber plug 22, so that it blocks the through hole 19, thereby avoiding sample leakage and achieving the purpose of quickly extracting the sample.

[0052] The above are only the preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent replacements, and improvements made within the spirit and principle of the present utility model shall be included within the protection scope of the present utility model.
