Description

Technical Field

[0001] This utility model relates to the field of food sampling technology, and in particular to a portable sampling device for food safety testing. Background Technology

[0002] Food sampling is a crucial step in food safety testing. It involves taking a portion of a substance, material, or product as a representative sample for testing or calibration. Samples are randomly selected from a large batch of food products, ensuring that all parts of the food have an equal chance of being collected. Common random sampling methods include simple random sampling, systematic random sampling, and stratified random sampling. Existing food sampling devices are often box-shaped, bulky, cumbersome, and inadequate for small-scale sampling. Therefore, we are introducing a portable food safety testing sampling device. Utility Model Content

[0003] The main objective of this invention is to provide a portable sampling device for food safety testing, which can effectively solve the problems in the background art.

[0004] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0005] A portable sampling device for food safety testing includes a sample storage cylinder. A lower cover plate is threadedly connected to the lower end of the sample storage cylinder, and an upper cover plate is threadedly connected to the upper end of the sample storage cylinder. A handle is fixedly connected to the right side of the outer surface of the sample storage cylinder. A first sampling device is inserted and fixedly connected to the upper left side of the sample storage cylinder, and a second sampling device is inserted and fixedly connected to the upper right side of the sample storage cylinder. Internal threads are provided on the upper part of the inner wall of the lower cover plate and the lower part of the inner wall of the upper cover plate.

[0006] Preferably, the sample storage cylinder has storage cavities at both the front and rear of its upper end, and sealing plugs are inserted into both storage cavities. The sample storage cylinder has a second through slot on the left side of its upper end and a first through slot on the right side of its upper end. The sample storage cylinder has external threads on its lower and upper outer surfaces, and observation windows on its front and rear outer surfaces.

[0007] Preferably, the two observation windows correspond to the positions of the two storage cavities, respectively.

[0008] Preferably, the second sampling device includes a circular block, with a pull rod movably connected to the upper end of the circular block, a sponge head fixedly connected to the lower end of the pull rod, and a pull ring fixedly connected to the upper end of the pull rod.

[0009] Preferably, the circular block is fixedly connected to the inner wall of the first slot.

[0010] Preferably, the first sampling device includes a sleeve, a piston is slidably connected inside the sleeve, the upper end of the piston is fixedly connected to a connecting rod, a suction head is fixedly connected to the lower end of the sleeve, and a pull block is fixedly connected to the upper end of the connecting rod.

[0011] By adopting the above technical solution: after the lower cover is closed, the lower cover will block the end of the suction head, preventing liquid from flowing out of the suction head.

[0012] Preferably, the sleeve is inserted and fixedly connected to the second slot.

[0013] This utility model has the following beneficial effects:

[0014] 1. In this utility model, a sample storage tube is provided, with an upper cover plate threaded to the upper end and a lower cover plate threaded to the lower end. The upper and lower cover plates together cover the upper and lower ends of the sample storage tube, protecting the sample and sampling tools inside the sample storage tube. The sample storage tube can be lifted with one hand for carrying and sampling operations through the handle on the outer surface of the sample storage tube. The sample storage tube has a compact structure and small size, making it suitable for use in small-scale sampling operations.

[0015] 2. In this utility model, by opening two storage cavities in the sample storage cylinder, granular food can be stored. The first sampling device in the sample storage cylinder, through the cooperation of the sleeve, piston and connecting rod, can sample liquid food. The second sampling device in the sample storage cylinder, by pushing the pull rod downward, the sponge head at one end of the pull rod extends out of the sample storage cylinder, which can sample viscous food, making it convenient to sample different foods.

[0024] Please see Figure 1-4 This utility model provides a technical solution:

[0025] A portable sampling device for food safety testing includes a sample storage cylinder 1, a lower cover plate 6 threadedly connected to the lower end of the sample storage cylinder 1, an upper cover plate 3 threadedly connected to the upper end of the sample storage cylinder 1, a handle 5 fixedly connected to the right side of the outer surface of the sample storage cylinder 1, a first sampling device 2 inserted and fixedly connected to the upper left side of the sample storage cylinder 1, a second sampling device 4 inserted and fixedly connected to the upper right side of the sample storage cylinder 1, and internal threads 7 provided on the upper part of the inner wall of the lower cover plate 6 and the lower part of the inner wall of the upper cover plate 3.

[0026] In this embodiment, the upper front and upper rear of the sample storage cylinder 1 are both provided with storage cavities 15, and sealing plugs 11 are inserted into both storage cavities 15. The upper left of the sample storage cylinder 1 is provided with a second through slot 16, and the upper right of the sample storage cylinder 1 is provided with a first through slot 12. The lower part and the upper part of the outer surface of the sample storage cylinder 1 are provided with external threads 13, and the front part and the rear part of the outer surface of the sample storage cylinder 1 are provided with observation windows 14. The two observation windows 14 correspond to the positions of the two storage cavities 15 respectively.

[0027] The above solution involves two storage chambers 15 inside the sample storage cylinder 1. These two independent storage spaces can store granular food separately, effectively avoiding cross-contamination between different samples.

[0028] In this embodiment, the second sampling device 4 includes a circular block 41, with a pull rod 42 movably connected to the upper end of the circular block 41, a sponge head 43 fixedly connected to the lower end of the pull rod 42, and a pull ring 44 fixedly connected to the upper end of the pull rod 42; the circular block 41 is fixedly connected to the inner wall of the first slot 12; the first sampling device 2 includes a sleeve 21, with a piston 24 slidably connected inside the sleeve 21, a connecting rod 23 fixedly connected to the upper end of the piston 24, a suction head 25 fixedly connected to the lower end of the sleeve 21, and a pull block 22 fixedly connected to the upper end of the connecting rod 23; the sleeve 21 is inserted and fixedly connected to the second slot 16.

[0029] Through the above scheme, the coordinated work of sleeve 21, piston 24 and connecting rod 23 can achieve accurate and leak-free liquid sampling, ensuring the integrity and representativeness of the sample. For sampling viscous food, the user only needs to gently push the pull rod 42 down, and the sponge head 43 at the end of the pull rod 42 will smoothly extend into the sample storage cylinder 1. With its good adsorption and softness, it can easily and completely collect viscous samples.

[0030] It should be noted that this utility model describes a portable sampling device for food safety testing. The upper end of the sample storage cylinder 1 is threadedly connected to an upper cover plate 3, and the lower end is also threadedly connected to a lower cover plate 6. This not only ensures the sealing of the sample storage cylinder 1 and prevents the sample from being contaminated or leaked by the external environment, but also allows the upper cover plate 3 and the lower cover plate 6 to be easily disassembled and assembled, making it convenient for users to store and retrieve samples. The handle 5 on the outer surface of the sample storage cylinder 1 enables quick and convenient carrying and operation, whether for outdoor sampling or transfer within the laboratory. The sample storage cylinder 1 has two storage cavities 15 inside. These two independent storage spaces can store granular food separately, effectively avoiding cross-contamination between different samples. For sampling liquid foods, the coordinated operation of the sleeve 21, piston 24, and connecting rod 23 enables accurate and leak-free liquid sampling, ensuring the integrity and representativeness of the sample. For sampling viscous foods, the user only needs to gently push the pull rod 42 downwards, and the sponge head 43 at the end of the pull rod 42 will smoothly extend into the sample storage cylinder 1. With its good adsorption and softness, it can easily and completely collect viscous samples, meeting the sampling needs of various forms of food.
