Detailed Implementation
[0025] Please see Figure 4 and Figure 5A food testing sampler includes a sampling cylinder 1, a stabilizing plate 2 fixedly connected to one end of the sampling cylinder 1, a pushing through hole at one end of the stabilizing plate 2, a pushing rod 3 slidably connected inside the pushing through hole, a pushing plug 4 fixedly connected to one end of the pushing rod 3, a silicone sealing strip fixedly connected to the outer wall of the pushing plug 4, two limiting blocks 5 fixedly connected to the outer wall of the sampling cylinder 1, each limiting block 5 having a limiting groove at one end, and a food liquid sampling mechanism and a food solid sampling mechanism installed inside each limiting groove via a limiting mechanism. The limiting mechanism includes a pushing box 16, one end of which is fixedly connected to one end of the limiting block 5, and a slot extending through the limiting groove at one end of the pushing box 16. A limiting groove is provided at one end of the mounting rod 6, and limiting sliders 17 are slidably connected to both ends inside the limiting groove. A fixed connection is provided between the two limiting sliders 17. A stabilizing spring 19 is fixedly installed between the bottom end of the tilting limit block 18 and the bottom end of the limiting groove. Pushing sliders 20 are slidably connected to both ends inside the push box 16. A pushing block 21 is fixedly connected between the two pushing sliders 20. By extending the mounting rod 6 into the limiting groove until the tilting limit block 18 extends into the slot, the installation of the food liquid sampling mechanism or the food solid sampling mechanism is completed. When replacing the food liquid sampling mechanism and the food solid sampling mechanism, pressing the pressing plate 22 will drive the pushing block 21 to contact the tilting limit block 18, causing the tilting limit block 18 to move away from the slot, thereby completing the disassembly of the food liquid sampling mechanism or the food solid sampling mechanism, further improving the efficiency of food testing. The sampling component can sample liquids or solids and is suitable for sampling various foods.
[0026] Please see Figure 1 , Figure 2 and Figure 3The food liquid sampling mechanism includes two mounting rods 6, with a mounting component 7 fixedly connected between the bottom ends of the two mounting rods 6. A sampling tube 8 is fixedly connected to one end of the mounting component 7, and a sampling plate 9 is fixedly connected inside the sampling tube 8. One end of the sampling plate 9 has three sampling through holes, two of which have sampling sieve plates 10 fixedly installed inside. The two sampling sieve plates 10 have different sieve diameters. A circular ring plate 11 is rotatably connected to the outer wall of the sampling tube 8. A rotating cylinder 12 is fixedly connected to one end of the circular ring plate 11, and a rotating plate 13 is fixedly connected to one end of the rotating cylinder 12. A sampling groove is provided at one end of the rotating plate 13. The food solid sampling mechanism also includes two mounting rods 6. A sampling block 14 is fixedly connected to the other end of the sampling block 14, and a tube 15 is fixedly connected to the other end of the sampling block 14. A slot is opened at one end of the sampling block 14. By rotating the annular plate 11, the rotating cylinder 12 and the rotating plate 13 will be driven to rotate, and the position of the sampling channel will be adjusted. By screening the liquid through the two sampling sieve plates 10, its application scenarios are improved. If it is not necessary to sample the impurities inside the liquid, by rotating the rotating cylinder 12, its sampling channel is aligned with one of the sampling sieve plates 10 to screen and filter the food liquid. After the food solid sampling mechanism is installed, the tube 15 is inserted into the interior of the solid food to complete the sampling of the solid food.
[0027] It should also be noted that a pressing plate 22 is fixedly connected to the top of the push block 21, and multiple return springs 23 are installed between the bottom end of the pressing plate 22 and one end of the limit box. The tension of the return springs 23 is used to achieve the reset effect of the pressing plate 22. Two hand plates 24 are fixedly connected to the outer wall of the sampling cylinder 1. A push plate 25 is fixedly connected to one end of the push rod 3, and a hand handle 26 is fixedly connected to one end of the push plate 25, which improves the convenience for users. A silicone sealing layer 27 is fixedly connected to the bottom of the sampling cylinder 1 to improve the sealing between the sampling cylinder 1 and the food liquid sampling mechanism and the food solid sampling mechanism.
[0028] In summary, when using this food testing sampler, first insert the mounting rod 6 into the limiting groove until the tilting limit block 18 extends into the slot, thus completing the installation of the liquid or solid food sampling mechanism. When replacing the liquid or solid food sampling mechanism, pressing the pressing plate 22 causes the pushing block 21 to contact the tilting limit block 18, moving it away from the slot, thereby disassembling the liquid or solid food sampling mechanism and further improving the efficiency of food testing. When sampling liquids, the liquid food sampling mechanism is then installed... After installation, by pulling the push rod 3, liquid food is sampled through a syringe-like extraction mechanism. The rotation of the annular plate 11 drives the rotating cylinder 12 and rotating plate 13 to rotate, and the position of the sampling channel is adjusted. The liquid is screened by the two sampling sieve plates 10, improving its application scenarios. If it is not necessary to sample the internal impurities of the liquid, the rotation of the rotating cylinder 12 aligns its sampling channel with one of the sampling sieve plates 10 to screen and filter the liquid food. After the solid food sampling mechanism is installed, the insertion tube 15 is inserted into the interior of the solid food to complete the sampling of the solid food.
