Description

Technical Field

[0001] This utility model relates to the technical field of sampling devices for food inspection, and in particular to a sampling device for food inspection. Background Technology

[0002] Food inspection is the process of conducting various tests and analyses on food to determine its quality, safety, and compliance. This process aims to ensure that food meets national regulations and standards, protecting public health. Food inspection methods include a variety of techniques such as chemical analysis, physical testing, and microbiological testing. Chemical analysis is mainly used to detect nutrients, additives, pesticide residues, and heavy metals in food, while physical testing mainly includes testing for quality, appearance, and purity.

[0003] There are many existing food testing methods, and the state of the samples tested varies for each method. Furthermore, due to the large variety and significant differences in food types, it is necessary to separate solid-liquid mixtures when testing them to improve convenience and accuracy. However, existing food testing sampling devices cannot separate solid-liquid mixtures, making them inconvenient to use. Therefore, we provide a food testing sampling device. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing food inspection sampling devices that cannot separate solid-liquid mixtures in food, and to provide a food inspection sampling device.

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] Example 1

[0026] like Figures 1-5 As shown, this utility model provides a technical solution: a sampling device for food inspection, comprising: a sampling mechanism 1, the sampling mechanism 1 including a liquid holding tank 11, a connecting pipe 12 at the top of the liquid holding tank 11, a top pipe 13 at the top of the connecting pipe 12, a first separation net 14 sleeved inside the liquid holding tank 11, the first separation net 14 being slidably connected to the liquid holding tank 11, a second separation net 15 sleeved inside the connecting pipe 12, the second separation net 15 being slidably connected to the connecting pipe 12, and a third separation net 13 sleeved inside the top pipe 13. 16. Separating net 3 16 is slidably connected to the jacking pipe 13. The outer surface of the jacking pipe 13 is fitted with a top cover 17. The top cover 17 is threadedly connected to the jacking pipe 13. A handle 18 is fixedly connected to the top of the top cover 17. Positioning posts 19 are fixedly connected to the bottom of separating net 1 14, separating net 2 15 and separating net 3 16. Positioning grooves that fit with positioning posts 19 are opened in the liquid tank 11, connecting pipe 12 and jacking pipe 13. Clip grooves 101 are opened on separating net 1 14, separating net 2 15 and separating net 3 16.

[0027] In this embodiment, by setting up a sampling mechanism 1, food testing personnel can initially separate food in a solid-liquid mixture. A liquid container 11 is set up to hold liquid samples. Separation nets 14, 15, and 3 are set up to classify solid and paste samples. Larger solid samples can be retained in separation net 3 16, and similarly, paste samples will be retained in separation net 14. This allows the sampling mechanism 1 to not only perform solid-liquid separation but also to separate solid samples, thereby improving the convenience of sample collection for food testing personnel. It can also better match different testing methods and testing needs. The slots 101 on separation nets 14, 15, and 3 16 make it easier to install and remove them.

[0028] Example 2

[0029] like Figures 1-5 As shown, a connecting mechanism 2 is provided on one side of the sampling mechanism 1. The connecting mechanism 2 includes two connecting blocks 21. The connecting blocks 21 are fixedly connected to the outer surfaces of the liquid container 11 and the connecting tube 12. Two connecting blocks 22 are provided on the top of the connecting blocks 21. The connecting blocks 22 are fixedly connected to the outer surfaces of the connecting tube 12 and the top tube 13. An insert block 23 is sleeved inside the connecting blocks 21. The insert block 23 is slidably connected to the connecting blocks 21. The insert block 23 is fixedly connected to the connecting blocks 22. A spring piece 24 is fixedly connected to the outer surface of the insert block 23. A squeezing block 25 is provided on one side of the spring piece 24. A sliding rod 26 is fixedly connected to one side of the squeezing block 25. The sliding rod 26 passes through the interior of the connecting blocks 21. The sliding rod 26 is slidably connected to the connecting blocks 21. A pressing block 27 is fixedly connected to one end of the sliding rod 26.

[0030] In this embodiment, by setting a connecting mechanism 2, some components in the sampling mechanism 1 can be easily connected and separated. A spring sheet 24 is set, and the deformation of the spring sheet 24 can generate elastic force, so the spring sheet 24 can be locked inside the connecting block 1 21. Under the action of the spring sheet 24, the connecting block 1 21 and the connecting block 22 can be in a tight fit. In addition, a squeezing block 25, a sliding rod 26 and a pressing block 27 are set so that food testing personnel can quickly contact the connection between the connecting block 1 21 and the connecting block 22.

[0031] Working principle:

[0032] like Figures 1-5As shown, in use, the top cover 17 can be rotated by the handle 18, causing the threaded connection between the top cover 17 and the top tube 13 to disengage. Then, the food in a solid-liquid mixture is poured into the third separation mesh 16. Larger, solid samples will remain in the third separation mesh 16, and so on. Smaller solid samples will remain in the second separation mesh 15, while paste-like samples will remain in the first separation mesh 14. Finally, the liquid sample will leak into the liquid container 11. The food is then left to stand for a certain period to allow for complete solid-liquid separation. After separation, the liquid container 11, connecting tube 12, and top tube 13 can be gradually separated. First, the top tube 13 is separated from the connecting tube 12. Pressing the pressing block 27 causes the sliding rod 26 to slide within the first connecting block 21. While sliding, the sliding rod 26 can drive the squeezing block 25 to slide. At the same time, the squeezing block 25 will squeeze the spring piece 24, causing the spring piece 24 to partially deform and disengage from the slot inside the connecting block 1 21. Then, the top tube 13 is lifted, and the top tube 13 drives the connecting block 22, the insert block 23 and the spring piece 24 to move upward until the insert block 23 and the spring piece 24 are completely disengaged from the connecting block 1 21. At this time, the top tube 13 and the connecting tube 12 are separated. In this way, the connecting tube 12 is separated from the liquid container 11. After that, solid samples, paste samples and liquid samples can be sampled in a matching manner according to different food testing methods to complete the food testing work. After the food testing is completed, the components in the sampling mechanism 1 need to be further separated for thorough cleaning and disinfection.

[0033] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
