In current testing methods, when testing powdered foods, manual sampling is mostly used. During manual sampling, there are situations where the powdered samples are contaminated by bacteria on the skin and microorganisms on the gloves. Moreover, during the sampling process, due to differences in the subjective judgment of operators and inconsistent techniques, the sampling amount is inconsistent, thus affecting the accuracy of the test results. Content of the Utility Model

[0003] The purpose of the present utility model is to provide a sampling device for food testing to solve the above problems.

[0004] The technical solution of the present disclosure is realized as follows:

[0005] The present disclosure provides a sampling device for food testing, including a sampling cylinder, a material taking rod, and an elastic support member. A receiving groove is provided inside the sampling cylinder. An outlet cylinder is provided at the bottom of the sampling cylinder, and the inside of the outlet cylinder is communicated with the receiving groove. An opening is provided at one end of the sampling cylinder.

[0006] The material taking rod is movably arranged in the receiving groove. One end of the material taking rod extends to the outside of the sampling cylinder and is equipped with a pulling handle. A material holding part is provided on the material taking rod. When the pulling handle approaches the sampling cylinder by moving the material taking rod in the receiving groove, the material holding part moves through the opening to the outside of the sampling cylinder.

[0007] When the material taking rod rotates, the material holding part rotates synchronously.

[0008] An isolation seat is provided inside the sampling cylinder. The isolation seat has an opening for the material taking rod to pass through. The isolation seat forms a moving area and a material placing area inside the sampling cylinder. The elastic support member is located in the moving area.

[0009] The elastic support member includes an elastic member and an annular bearing seat. The annular bearing seat is sleeved on the material taking rod. A bearing is provided at the connection between the annular bearing seat and the material taking rod. One end of the elastic member is connected to the isolation seat, and the other end is connected to the annular bearing seat.

[0010] In one embodiment, a moving track communicated with the receiving groove is provided on the sampling cylinder. A guiding rod is provided on the material taking rod, and one end of the guiding rod passes through the moving track.

[0011] The moving track includes a horizontal track and an arc track. The arc track is arranged on one side of the horizontal track close to the pulling part. The arc track and the horizontal track are interconnected and vertically distributed.

[0012] When the guide rod moves on the moving track, the position and angle of the material holding part change synchronously.

[0013] In one embodiment, through the cooperation of the guide rod and the moving track, the material holding part has a material taking state and a material placing state.

[0014] When in the material taking state, the pulling part is close to the sampling cylinder, the guide rod moves along the horizontal track to one end far from the arc track, and the annular bearing seat is close to the isolation seat, and the material holding part is located outside the sampling cylinder.

[0015] When in the material placing state, the pulling part gradually moves away from the sampling cylinder, the guide rod moves along the horizontal track to one end close to the arc track, and moves along the arc track, so that the angle of the material holding part changes, and the opening direction of the material holding part gradually faces the discharge cylinder.

[0016] In one embodiment, a support rod is arranged at one end of the material holding part far from the material taking rod, and a dust-proof pad is installed on the support rod.

[0017] When the material holding part is located in the accommodating groove, the outer peripheral surface of the dust-proof pad fits with the inner wall of the opening, so that the dust-proof pad covers the opening.

[0018] In one embodiment, a scraping component is further included. The scraping component is arranged on the sampling cylinder and above the opening.

[0019] The scraping component includes a placement seat and a scraping plate. The placement seat is arranged on the sampling cylinder, a sliding groove is provided in the placement seat, and one end of the scraping plate is movably arranged on the sliding groove.

[0020] By moving the scraping plate in the sliding groove, the tip of the scraping plate fits with the top of the material holding part.

[0021] In one embodiment, a first magnetic layer is arranged on one side of the sampling cylinder facing the pulling part, and a second magnetic layer is arranged on the pulling part.

[0022] Through the cooperation of the first magnetic layer and the second magnetic layer, when the pulling part fits with the sampling cylinder, the pulling part is magnetically connected to the sampling cylinder.

[0023] In one embodiment, a scraping disc is further arranged on the material taking rod, and the outer peripheral surface of the scraping disc abuts against the inner wall of the accommodating groove.

[0024] The scraping disc is located in the material placing area.

[0025] In one embodiment, a material bottle is further included, and the material bottle is installed at the bottom of the discharge cylinder.

[0026] The advantages or beneficial effects in the above technical solutions at least include:

[0027] The present disclosure relates to a sampling device for food detection. When a tester pushes the pulling part to make it close to the sampling cylinder, since the pulling part is arranged at one end of the material taking rod and the material taking rod is provided with a material holding part, when the pulling part moves, the material taking rod will drive the material holding part to move relatively, so that the material holding part moves to the outside of the sampling cylinder and sampling operation is carried out. After sampling is completed, since the annular bearing seat in the material taking rod is connected to the isolation seat arranged in the sampling cylinder through an elastic member, when the force applied to the pulling part is released, the compressed elastic member can be reset, thereby driving the material taking rod to move, making the material holding part move into the sampling cylinder, and by rotating the material taking rod, the opening direction of the material holding part is rotated to the discharge cylinder, thus completing the sampling operation, improving the accuracy of sampling. During the sampling process, the tester will not directly contact the test material, solving the problem of the risk of contaminating the test material during manual detection.

[0044] The names of the messages or information exchanged between multiple devices in the implementation manners of the present disclosure are only for illustrative purposes and are not used to limit the scope of these messages or information.

[0045] Refer to Figures 1 - 5, A sampling device for food detection, comprising a sampling cylinder 1, a material taking rod 2 and an elastic support member 3. The elastic support member 3 is used to drive the material taking rod 2 to move. A receiving groove 11 is provided in the sampling cylinder 1. An outlet cylinder 12 is provided at the bottom of the sampling cylinder 1. The outlet cylinder 12 communicates with the outside, and the inside of the outlet cylinder 12 communicates with the receiving groove 11. An opening 13 is provided at one end of the sampling cylinder 1;

[0046] The material taking rod 2 is movably arranged in the receiving groove 11. One end of the material taking rod 2 extends to the outside of the sampling cylinder 1 and is provided with a pulling handle 21. A material holding part 22 is provided on the material taking rod 2. When the pulling handle 21 approaches the sampling cylinder 1 by moving the material taking rod 2 in the receiving groove 11, the material holding part 22 moves through the opening 13 to the outside of the sampling cylinder 1;

[0047] When the material taking rod 2 rotates, the material holding part 22 rotates synchronously, so that the detected material in the material holding part 22 falls into the outlet cylinder 12 under the action of gravity;

[0048] An isolation seat 14 is provided in the sampling cylinder 1. The isolation seat 14 has an opening 13 for the material taking rod 2 to pass through. The isolation seat 14 forms a moving area and a material placing area in the sampling cylinder 1. The elastic support member 3 is located in the moving area, and the material holding part 22 is located in the material placing area;

[0049] The elastic support member 3 includes an elastic member 31 and an annular bearing seat 32. The annular bearing seat 32 is sleeved on the material taking rod 2. A bearing is provided at the connection between the annular bearing seat 32 and the material taking rod 2. When the material taking rod 2 rotates, the annular bearing seat 32 keeps the angle unchanged. One end of the elastic member 31 is connected to the isolation seat 14, and the other end is connected to the annular bearing seat 32. The elastic member 31 is any one of a telescopic spring, a compression spring or a torsion spring in the prior art.

[0050] Through the cooperation of the guide rod 23 and the moving track 4, the material holding part 22 has a material taking state and a material placing state;

[0051] When in the material taking state, the pulling handle 21 approaches the sampling cylinder 1, so that the guide rod 23 moves along the horizontal track 41 to the end far from the arc track 42, and the annular bearing seat 32 approaches the isolation seat 14. The material holding part 22 is located outside the sampling cylinder 1. The movement of the material holding part 22 is driven by the cooperation of the guide rod 23. When in the material placing state, the pulling handle 21 gradually moves away from the sampling cylinder 1, so that the guide rod 23 moves along the horizontal track 41 to the end close to the arc track 42 and moves along the arc track 42, so that the angle of the material holding part 22 changes, and the opening direction of the material holding part 22 gradually faces the outlet cylinder 12. When in the material placing state, the guide rod 23 is parallel on the horizontal track 41. When located on the arc track 42, the angle of the material holding part 22 gradually inclines;

[0052] Based on the above structure, since the pulling part 21 is arranged at one end of the material taking rod 2, the tester drives the material taking rod 2 to move by squeezing the pulling part 21 located outside the sampling cylinder 1, drives the elastic part 31 to be compressed, and makes the material holding part 22 on the material taking rod 2 move outside the sampling cylinder 1, so as to sample the test material that needs to be sampled. During the sampling process, the operator will not contact the test material, avoiding the pollution of the test material. Moreover, since the annular bearing seat 32 on the material taking rod 2 is connected to the elastic part 31, when the force applied to the pulling part 21 is released, the elastic part 31 resets, and the annular bearing seat 32 drives the material taking rod 2 to move in position under the cooperation of the elastic part 31, making the material holding part 22 move to the position of the discharge cylinder 12. When the material taking rod 2 rotates, it drives the material holding part 22 to rotate so that the opening of the material holding part 22 faces the discharge cylinder 12, and the test material in the material holding part 22 falls into the discharge cylinder 12. During the sampling process, the operator will not contact the test material, solving the problem of pollution to the test material during the manual sampling process.

[0053] In one implementation, referring to Figures 1 - 5 , a moving track 4 communicating with the accommodating groove 11 is arranged on the sampling cylinder 1, a guiding rod 23 is arranged on the material taking rod 2, one end of the guiding rod 23 passes through the moving track 4, and the moving track 4 is used to limit the guiding rod 23 so that the guiding rod 23 can move smoothly during the moving process;

[0054] The moving track 4 includes a horizontal track 41 and an arc track 42. The arc track 42 is arranged on the side of the horizontal track 41 close to the pulling part 21. The arc track 42 and the horizontal track 41 are interconnected and vertically distributed. When the guiding rod 23 moves on the moving track 4, the position and angle of the material holding part 22 change synchronously. By setting the horizontal track 41 and the arc track 42, the moving distance of the guiding rod 23 is set so that it can only move in the moving track 4, thereby controlling the moving distance of the material taking rod 2 and realizing the stable movement of the material taking rod 2 driving the material holding part 22.

[0055] In one implementation, referring to Figure 1 and Figure 4 , a support rod 221 is arranged at one end of the material holding part 22 far from the material taking rod 2, and a dust-proof pad 222 is installed on the support rod 221. The dust-proof pad 222 is made of rubber material and has certain ductility. When the material holding part 22 is located in the accommodating groove 11, the outer peripheral surface of the dust-proof pad 222 fits with the inner wall of the opening 13, so that the dust-proof pad 222 covers the opening 13.

[0056] In one implementation, referring to Figure 1 , Figure 3 and Figure 6, further comprising a scraping component 5, the scraping component 5 is arranged on the sampling tube 1 and located above the opening 13;

[0057] The scraping component 5 includes a storage seat 51 and a scraper 52. The storage seat 51 is arranged on the sampling tube 1. A slide groove 511 is provided in the storage seat 51. One end of the scraper 52 is movably arranged on the slide groove 511. The scraper 52 is moved in the slide groove 511 to adjust the position of the scraper 52, so as to realize the scraping operation of the detection objects of different capacities. The scraper 52 moves in the slide groove 511 so that the tip of the scraper 52 fits with the top of the material holding part 22. When the scraper 52 remains stationary and the material holding part 22 moves, the detection material in the material holding part 22 is scraped flat by the scraper 52.

[0058] In one embodiment, referring to Figures 1 - 5 A first magnetic layer 15 is provided on the side of the sampling tube 1 facing the handle portion 21, and a second magnetic layer 211 is provided on the handle portion 21. Through the cooperation of the first magnetic layer 15 and the second magnetic layer 211, when the handle portion 21 is in contact with the sampling tube 1, the handle portion 21 is magnetically connected to the sampling tube 1. The magnetic connection method can improve the stability of the handle portion 21 during sampling, and avoid shaking of the material holding portion 22 when the handle portion 21 shakes.

[0059] In one embodiment, referring to Figure 1 , Figure 3 and Figure 5 A scraper 24 is also provided on the material taking rod 2, and the outer peripheral surface of the scraper 24 is against the inner wall of the receiving groove 11. The scraper 24 is located in the material placing area. A slot is also provided in the sampling tube 1. By the scraper 24 being against the inner wall of the receiving groove 11, when the scraper 24 moves, the impurities remaining in the receiving groove 11 can be scraped off and discharged through the slot position.
