[0002] With the progress and development of society, food safety has attracted more and more attention. Liquid food is generally sampled through a liquid food sampling device.

[0003] Publication No. CN214309700U discloses a liquid food sampling device for food testing, comprising an operating table and a lifting frame. The operating table has a clamping groove defined within it, and a clamping structure is disposed within the groove. A lifting frame is vertically mounted on one end of the top of the operating table, and the lifting structure is disposed at the bottom of the lifting frame. The lifting structure also includes a threaded rod, which is disposed at the bottom of the lifting frame via a bearing, and the top of the threaded rod extends through the top of the lifting frame. A threaded block that matches the threaded rod is slidably connected to the lifting frame outside the threaded rod, and connecting rods are mounted on the upper and lower ends of the front of the threaded block. Although this liquid food sampling device utilizes the lifting structure to rotate the threaded rod, causing the threaded block to move the connecting rod, outer cylinder, and inner cylinder downward to different heights, thereby obtaining liquid food at different depths and improving sampling results, this liquid food sampling device, however, mixes the liquid food obtained at different depths, making it impossible to sample samples at different depths separately, which affects the detection effect. Therefore, improvements are needed. Utility Model Content

A placement plate 4 is fixedly mounted on the surface of the electric slide 3, and the placement plate 4 can be installed on the electric slide 3 by threaded connection or snap connection. The threaded connection is convenient for adjusting the position of the placement plate 4, while the snap connection is convenient and fast, and is suitable for occasions where frequent adjustments are made. A scale 14 is provided on the surface of the placement plate 4, and the scale 14 is marked by etching or silk screen technology to ensure the accuracy and durability of the scale 14. The staff can accurately adjust the equipment according to the scale 14. A pointer 15 is fixedly mounted on the side of the slider 8, and the pointer 15 points to the scale 14, so that the operator can adjust the sampling depth according to the scale 14. The pointer 15 is fixed to the slider 8 via an embedded structure, ensuring that it will not fall off during the sliding process. A top block 5 is fixedly mounted on the surface of the placement plate 4. The top block 5 is fixed by bolts or welding. Bolting facilitates future disassembly and maintenance, while welding is more stable and suitable for long-term use. A liquid pump 6 is fixedly mounted on the top surface of the top block 5. The liquid pump 6 can be fixed to the top block 5 via a flange or threaded connection. The flange connection ensures the stability and sealing of the liquid pump 6 during operation, which meets the connection requirements of liquid flow equipment. The liquid pump 6 is responsible for extracting the food sample through the needle 10, ensuring smooth and accurate sampling. The surface of the placement plate 4 is provided with a chute 7. The chute 7 is precision-machined to ensure smooth sliding of the slider 8 within the chute 7 and reduce friction. The inner wall of the chute 7 is slidably connected to the slider 8. The slider 8 can be connected using a sliding guide rail or a ball bearing rail. The sliding guide rail is suitable for high-precision applications, while the ball bearing rail can reduce friction and improve sliding smoothness. A cylinder 9 is fixedly mounted on the surface of the slider 8. The cylinder 9 is fixed to the slider 8 by welding or snap connection.

There are two groups of cylinders 9. This design can sample the top and bottom layers of food by adjusting the positions of the two groups of cylinders 9 separately, ensuring that samples of different depths can be obtained in one operation, thereby improving the representativeness of the samples and the accuracy of sampling.

[0027] Example 2

[0028] See also Figure 4-5 , an auxiliary mechanism is provided on the surface of the placement plate 4, and the auxiliary mechanism includes a groove 16. The groove 16 is opened on the surface of the placement plate 4. The inner wall of the groove 16 is slidably connected with a short block 17. The short block 17 can be connected to the groove 16 by a guide rail or ball sliding. The guide rail sliding is suitable for high-precision requirements, and the ball sliding can improve the smoothness of sliding. A center block 18 is fixedly installed on the surface of the short block 17. The center block 18 is fixed by welding or bolts to ensure its stability and durability. A ring 19 is fixedly installed on the side of the center block 18. The ring 19 is symmetrically distributed on both sides of the center block 18. The ring 19 is installed on the center block 18 through an embedded structure, which can ensure that it is in close contact with the needle 10 during the downward pressing process to avoid displacement. Collar 19 is appropriately sized for needle 10 and is made of natural rubber, sponge, or alcohol wipes. Natural rubber and sponge effectively rub the tip of needle 10, scraping away food residue. Alcohol wipes provide both cleaning and disinfection functions, keeping needle 10 clean and preventing residue from drying and forming slag. A tension spring 20 is fixedly mounted between short block 17 and groove 16. The tension of spring 20 automatically resets short block 17 and center block 18 after operation, reducing the complexity of manual operation while ensuring a clean and efficient device.

[0029] Working principle: Place the food to be sampled on the operating table 1, and then use the electric slide 3 to drive the needle 10 to move downward until the needle 10 is immersed in the food, and then the food can be pumped out through the liquid pump 6 to sample the food. At the same time, since there are two groups of cylinders 9, the staff can rotate the screw rod 12 by twisting the cap 13. At this time, since there is a thread in the slider 8, the screw rod 12 can drive the slider 8 to slide in the slide groove 7. The slider 8 can then drive the cylinder 9 to move, and the cylinder 9 can then drive the needle 10 to move. In this way, the downward extension distance of the needle 10 can be adjusted. By adjusting the positions of the two groups of cylinders 9 respectively, the top and bottom layers of the food can be sampled separately, allowing multiple layers of liquid food of different depths to be obtained in one operation. The sample is obtained by adjusting the extension distance of the needle 10. At the same time, when adjusting the extension distance of the needle 10, the sliding process of the slider 8 can drive the pointer 15 to move, and the pointer 15 can point to the scale 14. The sampling position can be adjusted more accurately through the scale 14. The utility model uses two sets of cylinders 9 and adjustable needles 10 structures. The staff can sample the top layer and the bottom layer of the food respectively, so that food samples of different depths can be obtained in one operation, ensuring that the sample covers different layers of the entire food, thereby improving the accuracy of sampling and the representativeness of the sample. Moreover, through the slider 8 and the screw rod 12 structure, the extension distance of the needle 10 can be adjusted as needed. The sliding of the slider 8 drives the pointer 15 to point to the scale 14, and the operator can control the sample more accurately by observing the scale 14 The extension depth of the needle 10 ensures the accuracy and flexibility of sampling and adapts to the sampling needs of different foods. After the sampling is completed, the staff can pull the center block 18 downward to move, and the center block 18 can then drive the short block 17 to slide in the groove 16. At the same time, the center block 18 can drive the ring 19 to move downward. During the downward movement of the ring 19, it can rub the head of the needle 10, so that some food residues can be scraped off to prevent the food from drying and slagging at the needle 10. At the same time, if the ring 19 is made of sponge and alcohol cloth, it can also absorb moisture and disinfect. At the same time, due to the tension of the tension spring 20, the tension spring 20 can pull the short block 17 upward, and the short block 17 can then drive the center block 18 upward, and the center block 18 then drives the ring 1 9 Reset. The utility model can effectively scrape off food residues through the design of the downward pressure of the ring 19 and the friction of the needle 10 head, avoiding the residues from drying and forming slag at the needle 10, thus reducing the cleaning work after sampling, keeping the needle 10 in a clean state, and avoiding affecting the accuracy and sample quality of the next sampling. The needle 10 residues are easy to dry and form slag, which may cause damage to the equipment or affect the sampling efficiency. By scraping off the residues in time, this problem is avoided and the service life of the equipment is extended. Through the design of the tension spring 20, the staff only needs to pull the center block 18, and the ring 19 can be automatically reset, avoiding the complexity of manual operation, while keeping the cleaning process efficient and convenient, reducing manual intervention and improving work efficiency.
