Description

Technical Field

[0001] The invention relates to the technical field of food sampling, and in particular to a handheld food sampling device. Background Art

[0002] Food safety testing is to detect harmful substances in food according to certain standard indicators, mainly some harmful and toxic indicators, such as heavy metals, aflatoxin, etc. An important aspect of food science and engineering is to introduce and apply chemical unit operations and develop food engineering unit operations, so as to promote the development of the food industry in the direction of large-scale, continuous and automated. Food safety monitoring is a more important link in food safety testing. Among them, food safety monitoring is a complex process involving multiple links and technologies. Its main purpose is to ensure the safety of food from production to consumption. This process involves monitoring and management of food samples in food production, processing, storage, transportation and sales markets. Specifically, it requires sample collection, sample processing, experimental analysis, result evaluation and final report generation to determine whether there are safety problems with food.

[0003] After food production and processing, it is necessary to test the food quality, which involves the collection of food samples. That is, extracting a certain representative part of the samples from a large number of analysis objects as analysis materials. This work is called sampling. The collection of food samples requires that the samples are uniform and representative, and can reflect the composition, quality and hygiene status of all the tested foods.

[0004] Current food sampling devices include common sampling shovels, sampling probes and sampling cones, as well as sampling devices that combine the above-mentioned sampling shovels, sampling probes or sampling cones to achieve automatic sampling. The operator can control the sampling shovels, sampling probes and sampling cones to insert into food to complete sampling by operating the sampling device. However, the above-mentioned sampling operations all have sampling limitations. It is understandable that the sampling effect is single. For example, when it is necessary to sample different cooked foods for inspection, in order to avoid cross-contamination of the sampling device during the sampling process, the sampling device needs to be disassembled and cleaned after each sampling of different foods, and the samples taken need to be stored separately before sampling of other types of food can be continued, which greatly affects the sampling efficiency and reduces the convenience of sampling.

In some optional embodiments, the elastic portion 322 can be a spring or a rubber tube arranged in a bellows shape, at least three fixed rods 323 extending outward from the side of the movable plate 321 away from the elastic portion 322, and a sampling portion arranged on the side of the fixed rod 323 away from the movable plate 321, wherein the movable plate 321 moves along the trajectory of the positioning column 315 toward or away from the cover assembly 33, so that the surrounding edge of the movable plate 321 contacts the embedded spring buckle 314 and the positioning spring buckle 317 in turn.The sampling part includes a sampling cone 324 fixedly connected to the fixed rod 323, and a sampling tube 325 extending from the edge of the sampling cone 324 toward the fixed rod 323. The cover assembly 33 includes a fixed cover 331, and at least two buckle ends 332 extending outward from the fixed cover 331 toward the side close to the fixed tube 311. The buckle ends 332 are embedded in the bottom edge of the fixed tube 311 and buckled with the elastic buckle 316.

[0037] Before the specific implementation, the operator can perform a filling operation on the sampling assembly 3 in the handheld assembly 1. Specifically, the operator can first open the top cover assembly 12. In some optional embodiments, the top cover assembly 12 and the handheld tube 111 can be screwed or snap-fitted, that is, the installation method between the sleeve portion 121 and the top cover assembly end 112, so that the operator can facilitate the subsequent frequent disassembly and assembly of the top cover assembly 12. Afterwards, the operator can stack multiple sampling assemblies 3 in an end-to-end manner, such as Figure 5 As shown, the sampling assembly 3 is loaded sequentially along the top of the receiving groove 113. During the process, the limiting groove 312 set on the sampling assembly 3 can limit each other with the limiting portion 114 in the receiving groove 113 to ensure the stability of the sampling assembly 3 when it is loaded into the handheld assembly 1. In the process of filling the sampling assembly 3, it is only necessary to ensure that the sampling assembly 3 located at the end entering the handheld assembly 1 is parallel to the notch position of the receiving groove 113, and there is no need to further push the sampling assembly 3 into the handheld assembly 1. After completing the loading of the sampling assembly 3 in the handheld assembly 1, the top cover assembly 12 is closed, and finally the preparation work of the handheld food sampling device of the present application before use is completed.

[0038] In the specific implementation, before the sampling operation, the operator needs to push part of the sampling assembly 3 to the sampling end 116 by operating the top cover assembly 12. Specifically, the operator can press down the driving part 122 to drive the bottom pushing end 123 to press down, and push the multiple sampling assemblies 3 at the bottom to move downward uniformly. It should be noted that the driving part 122 and the pushing end 123 are designed as an integrated structure and are movably embedded in the sleeve part 121. When the sampling assembly 3 is loaded into the handheld assembly 1 and the top cover assembly 12 is closed, the pushing end 123 is restricted by the position of the sampling assembly 3 near the top cover assembly 12, so that the driving part 122 is in a state of extending out of the sleeve part 121, and when the operator presses down the driving part 122, the pushing end 123 near the sampling assembly 3 can be pushed downward. The sampling assembly 3 at the end 116 is partially pushed out. During this process, the damping shaft 118 arranged on the inner side of the sampling end 116 can apply pressure to the outer edge of the sampling assembly 3, thereby ensuring the stability of the sampling assembly 3 without affecting the pushing out of the sampling assembly 3, and preventing the sampling assembly 3 from escaping from the handheld assembly 1 during use. In some optional embodiments, a spring buckle can be further arranged between the driving portion 122 and the sleeve portion 121, and a button corresponding to releasing the spring buckle restriction is embedded on the sleeve portion 121. The spring buckle can be activated to lock the current position of the driving portion 122 after the driving portion 122 is fully embedded in the sleeve portion 121, so as to prevent the sampling assembly 3 from being compressed and recovered into the handheld assembly 1 during the subsequent sampling process due to the operation of inserting the sampling assembly 3 into the food. After that, the operator can use the sampling assembly 3. Specifically, the operator can first pull out the cover assembly 33 embedded in the bottom of the sampling piece 32. In some optional embodiments, the connection between the cover assembly 33 and the sampling piece 32 can also be a screw-connected installation. After that, the operator needs to control the sampling cone 324 in the sampling piece 32 to extend. Specifically, the operator can axially rotate the adjustment shaft 22 according to the second indicator mark 24 on the adjustment shaft 22 to align it with the first indicator mark 117 on the sampling end 116. During the process, the adjustment shaft 22 drives the telescopic top block 23 to rotate toward the embedded spring buckle 314, and finally embeds it into the fixed cylinder 311, and the embedded spring buckle 314 is arranged at the position, and the embedded spring buckle 314 is activated, so as to activate the activation. After activation, the embedded spring buckle 314 can be separated from the support on the bottom of the movable plate 321, so that the elastic part 322 on the top of the movable plate 321 pushes the movable plate 321 downward along the trajectory of the positioning column 315, and at the same time drives the bottom fixed rod 323, sampling cone 324 and sampling tube 325 to push out the fixed tube 311, and after the movable plate 321 reaches the bottom end of the positioning column 315, it is buckled with the positioning spring buckle 317 on the inner side of the fixed tube 311. It should be noted that the spring buckle and buckle used in the present application are conventional fixing structures that can be understood by those skilled in the art. In addition, a limiting plate for limiting the movable plate 321 is provided at the bottom end of the positioning column 315, which can prevent the movable plate 321 from falling out and can also cooperate with the positioning spring buckle 317 to ensure the stability of the movable plate 321. In addition,In some optional embodiments of the present invention, the operation of triggering the movable plate 321 to pop out after the embedded spring buckle 314 is activated can also be to directly disassemble the cover assembly 33, and place the fixed cylinder 311 against the food sampling area, trigger the embedded spring buckle 314 to make the movable plate 321 drive the sampling cone 324 to pop out towards the food and directly insert it into the food for sampling.

[0039] Next, the operator drives the extended sampling cone 324 into the cooked food by holding the handheld assembly 1, wherein the cooked food includes but is not limited to processed cooked food such as steamed buns, steamed buns, bread, cakes, meat, vegetables, etc. In some optional embodiments, the fixed rod 323 may also be provided with a scale bar to facilitate the operator to judge the depth of the sampling cone 324 inserted into the food to achieve accurate sampling, and then slowly pull out the sampling cone 324. During the process, the inverted sampling barrel 325 cuts the food and collects the cut food. It should be noted that the sampling barrel 325 is thinner at the edge, which can be understood as a blade-type design. During the process of taking out the food in the vertical direction, 325 forms an angle of 30° with the food, which can achieve efficient food cutting effect to complete the sample sampling operation. In addition, there are three sampling tubes 325, which can realize three sample collection operations at the same time. In laboratory analysis, it is often necessary to perform multiple tests on samples. The three samples can be used for different test purposes, such as one for preliminary testing, one for re-testing to confirm the accuracy of the preliminary test results, and one as a reserved sample for further analysis that may be needed later. This ensures to the greatest extent that the samples taken can truly reflect the properties of the overall material and improve the accuracy of subsequent sample analysis.

[0040] Next, after completing the sampling of the above-mentioned food, the operator only needs to place the cover assembly 33 at the bottom of the sampling cone 324 and apply a certain thrust upward to trigger the positioning spring buckle 317 to be retracted and disengaged from the clamping of the movable plate 321, until the buckle end 332 is inserted into the bottom end of the fixed cylinder 311 and is buckled with the elastic buckle 316. During the process, the sampling cone 324 is re-entered into the fixed cylinder 311 and cooperates with the cover assembly 33 to store the sample in the internal sampling cone 324. In addition, in some optional embodiments, the edge of the fixed cover 331 can also extend along the direction of the fixed cylinder 311 to form an arc wall adapted to its inner wall, such as Fig. 9As shown, when the fixed cover 331 is pushed toward the fixed cylinder 311, the positioning spring buckle 317 can be triggered by the arc wall to be recovered. At the same time, after the fixed cover 331 is completely fitted with the bottom of the fixed cylinder 311, the movable plate 321 is pushed by the arc wall to be re-engaged with the embedded spring buckle 314 to complete the recovery of the sampling member 32. At the same time, it should be noted that the adjustment shaft 22 must be rotated to control the telescopic top block 23 and the embedded spring buckle 314 to avoid the recovery being restricted. Finally, the operator can pull out the sampling assembly 3 after the buckling along the sampling end 116, and open the top cover assembly 12 again to insert the sampling assembly 3 that has completed the sampling into the accommodating groove 113 so that it is in contact with the accommodating groove 113. The slots 113 are positioned parallel to each other and snap on the top cover assembly 12 to complete the replacement of the sampling assembly 3. Afterwards, the operator can repeat the above operation to implement a cyclic push-type replacement of the sampling assembly 3 after each food sampling is completed, until multiple sampling assemblies 3 complete the sampling operation and then transfer the samples. The operation is simple and convenient, and it can be applied to a variety of food sampling. It also avoids cross contamination during the drug collection process. It should be noted that the sampling assembly 3 itself can effectively store and preserve the collected samples through the sample storage part 31 and the cover assembly 33 to avoid external contamination. In addition, the sampling assembly 3 is uniformly accommodated in the handheld assembly 1, which further plays an effect of isolating and protecting the samples.

[0041] In summary, the handheld food sampling device in the above embodiment of the present invention, through the top cover assembly 12, pushes at least one sampling assembly 3 along the trajectory of the accommodating groove 113 to the sampling end 116 to implement the sampling operation. When the sampling is completed, the sampling assembly 3 after sampling is taken out from the sampling end 116 and inserted along the side of the hand-held tube 111 away from the sampling end 116, and then the unused sampling assembly 3 is pushed out in sequence toward the sampling end 116 through the top cover assembly 12. The operator can repeat the above operation to implement a cyclic push-type replacement of the sampling assembly 3 in the hand-held assembly 1 after each completion of food sampling, until the samples are transported after multiple sampling assemblies 3 have completed the sampling operation. The operation is simple and convenient, and it can be applied to diversified food sampling. It also avoids cross contamination during the drug collection process, and solves the problem that the existing food sampling device has a single sampling effect, affects the sampling efficiency and reduces the convenience of sampling.
