[0028] The present invention will now be further described with reference to the accompanying drawings and specific embodiments.

[0029] Example 1, such as Figure 1-5As shown, a layered sampling device for testing soft and glutinous foods includes an outer sampling tube 1 and an inner sampling tube 2 sleeved within the outer sampling tube 1. The inner sampling tube 2 can slide inside the outer sampling tube 1. After sampling is completed, the inner sampling tube 2 can be pulled out from the outer sampling tube 1 to remove the sample. The bottom of the outer sampling tube 1 is provided with several sampling ports 3. Each sampling port 3 is equipped with an adjustable sliding plate 4. The sliding plate 4 can be adjusted to seal the sampling port 3, enabling sampling of different layers of the food, ensuring convenient and effective sampling. The bottom of the inner sampling tube 2 is provided with several rotatable sampling chambers 5. Each sampling chamber 5 corresponds to a sampling port 3. The rotating sampling chamber 5 can cut the food to be sampled by rotation, storing the food sample within the sampling chamber 5 through rotational cutting. Simultaneously, after sampling is completed, the sampling chamber 5 rotates to turn its opening away from the sampling port 3, ensuring that the sampled food is not affected by other layers of food when the sampling device is pulled out, thus guaranteeing the purity and sampling effect of the sample. An air extraction port 50 is provided at the top of the sampling chamber 5. The air extraction port 50 is connected to a vacuum pump 6. The vacuum pump is connected to the air extraction port. When the vacuum pump is working, it creates a vacuum inside the sampling chamber. During this vacuuming process, the soft and glutinous food will enter the sampling chamber. The sampling chamber can rotate, and after rotation, sampling of that layer of soft and glutinous food can be completed. An adjustment knob 7 is connected to the sliding plate 4. The sliding plate's position is controlled by a connected adjustment knob. This design allows for layered sampling of the soft, glutinous food to be tested. Specifically, when sampling the lower layer of the soft, glutinous food, the adjustment knob closes the sliding plate at the top and middle positions, and opens the sliding plate at the bottom. This allows sampling of the lower layer of the soft, glutinous food. This process can be repeated to complete multi-layer sampling or simultaneous sampling. A vacuum pump 6 is connected to the inner sampling tube 2. An adjustment knob 7 is connected to the outer sampling tube 1.

[0030] The side wall of the sampling port 3 is provided with a sliding groove 30. The sliding plate 4 is slidably connected to the sliding groove 30. The sliding groove 30 is arc-shaped, and the sliding plate 4 is also arc-shaped. The sliding groove 30 serves to guide the sliding plate 4, facilitating the adjustment of the sliding plate 4.

[0031] An installation groove 10 is provided inside the side wall of the sampling outer tube 1. A connecting tube assembly 8 is fitted into the installation groove 10. Several adjusting gears 9 are provided at both ends of the connecting tube assembly 8. The upper adjusting gear 9 is connected to the adjusting knob 7, and the lower adjusting gear 9 is connected to the sliding plate 4. The installation groove 10 is a long straight groove, and a rotatable and adjustable connecting tube assembly 8 is fitted into the installation groove 10. Adjusting gears 9 are provided at both ends of the connecting tube assembly 8. The upper adjusting gear 9 matches the adjusting knob 7, and the lower adjusting gear 9 matches the sliding plate 4. The sliding plate 4 is adjusted by adjusting the adjusting knob 7. The connecting tube assembly 8 plays an intermediate linkage role, ensuring that the sliding plate 4 on the sampling outer tube 1, which enters the soft and glutinous food, can be adjusted from the top of the sampling outer tube 1 during sampling, thereby achieving the effect of controlling multi-layer sampling.

[0032] A connecting hole 11 is provided between the mounting groove 10 and the sliding groove 30. The connecting hole 11 connects the mounting groove 10 and the sliding groove 30, and a connecting rod 40 is provided inside the connecting hole 11. One end of the connecting rod 40 is connected to the sliding plate 4. The other end of the connecting rod 40 is provided with a connecting gear tooth 41. The connecting gear tooth 41 corresponds to the adjusting gear 9. When the adjusting knob 7 is adjusted, the adjusting gear 9 located below the connecting pipe assembly 8 will rotate. When the adjusting gear 9 rotates, it meshes with the connecting gear tooth 41, causing the connecting rod 40 to move, thereby driving the sliding plate 4 to slide within the sliding groove 30. This realizes the function of controlling the sliding action of the sliding plate 4 by adjusting the adjusting knob 7, ensuring simple and practical operation.

[0033] The connecting pipe assembly 8 includes an outer connecting pipe 80, a middle connecting pipe 81, and an inner connecting pipe 82. The outer connecting pipe 80, middle connecting pipe 81, and inner connecting pipe 82 are sequentially connected. The length of the outer connecting pipe 80 is shorter than the length of the middle connecting pipe 81. The length of the middle connecting pipe 81 is shorter than the length of the inner connecting pipe 82. Both ends of the outer connecting pipe 80, middle connecting pipe 81, and inner connecting pipe 82 are connected to the adjusting gear 9. The adjusting knob 7 has three knobs corresponding to the outer connecting pipe 80, middle connecting pipe 81, and inner connecting pipe 82 respectively. This design allows any knob on the adjusting knob 7 to control the rotation of the corresponding pipe, thereby rotating the corresponding adjusting gear 9. The outer connecting pipe 80, middle connecting pipe 81, and inner connecting pipe 82 are connected in a sleeved manner to fix the adjusting gear at both ends of the pipe. After fixing, the outer contour of the adjusting gear is flush, facilitating matching and connection with the adjusting knob 7. This allows control of the sliding action of the corresponding sliding plate 4, ensuring multi-layer sampling.

[0034] A mounting ring 12 is connected to the top outer wall of the sampling outer tube 1. The mounting ring 12 provides the mounting position for the adjustment knob 7. An adjustment groove 13 is provided on the mounting ring 12. A mounting shaft 14 is connected to the adjustment groove 13. The adjustment knob 7 is sleeved with the mounting shaft 14. An adjustment gear tooth 70 is provided on the side wall of the adjustment knob 7. The adjustment gear tooth 70 corresponds to the adjustment gear 9. The three different knobs set by the adjustment knob 7 correspond from top to bottom to the sliding plates 4 in the sampling ports 3 arranged sequentially from top to bottom, which facilitates adjustment and ensures accurate operation.

[0035] A mounting chamber 20 is provided at the lower part of the sampling inner tube 2. The sampling chamber 5 is placed inside the mounting chamber 20. A rotating motor 21 is installed at the bottom of the mounting chamber 20. The rotating motor 21 is connected to the sampling chamber 5. The mounting chamber is used to hold the sampling chamber 5. The rotating motor 21 can drive the sampling chamber 5 to rotate. The rotating motor 21 is externally connected to a controller, which is installed on the mounting ring. By controlling the controller, the rotation of the corresponding rotating motor 21 is realized, thereby realizing the cutting and storage of food samples by the sampling chamber 5.

[0036] A connecting pipe 60 is provided on the top surface of the mounting chamber 20. The connecting pipe 60 is sleeved with the air extraction port 50. The connecting pipe 60 is connected to the vacuum pump 6. The connecting pipe 60 serves as the connection medium between the vacuum pump 6 and the air extraction port 50, ensuring that the vacuum pump 6 can suck soft and sticky food into the sampling chamber 5 during operation. It also ensures that the soft and sticky food sucked into the sampling chamber 5 can be vacuum-preserved through the rotation and cutting of the sampling chamber 5, ensuring that the soft and sticky food is in a vacuum-preserved state before being removed after sampling, thus ensuring the sampling effect of the soft and sticky food.

[0037] A cutting bevel 51 is provided at the opening of the sampling chamber 5. The beveled end of the cutting bevel 51 faces the inside of the sampling chamber 5. The cutting bevel 515 facilitates the cutting and sampling of soft and glutinous food entering the sampling chamber 5, ensuring the sampling effect.

[0038] A transition slope 22 is provided at the end of the sampling inner tube 2 facing the sampling port 3. The transition slope 22 facilitates the entry of soft and glutinous foods into the sampling chamber 5 and makes it easier to cut and sample.

[0039] The working principle of this invention is as follows: Figure 1-5As shown, before sampling, the inner sampling tube 2 is inserted into the outer sampling tube 1, and the inner sampling tube 2 is rotated so that the sampling port 3 is aligned with the opening of the sampling chamber 5 on the inner sampling tube 2. According to the sampling requirements, the adjustment knob 7 is adjusted so that the sliding plate 4 is in the closed state. The outer sampling tube 1 is inserted into the soft and sticky food, and according to the position of the sampling layer, the adjustment knob 7 is adjusted to open the corresponding sliding plate 4. Then, the vacuum pump 6 is started to suck the soft and sticky food into the sampling chamber 5. Next, the controller is operated so that the corresponding rotating motor 21 drives the sampling chamber 5 to rotate. A cutting bevel 51 is provided at the opening of the sampling chamber 5, which can cut the soft and sticky food when the sampling chamber 5 rotates. After rotation, the sampling chamber 5 faces away from the sampling port 3, allowing for the storage of soft and glutinous foods. Simultaneously, the vacuum state inside the sampling chamber 5 ensures the freshness of the sampled soft and glutinous foods, guaranteeing the sampling effect. After sampling, the inner sampling tube 2 is pulled out from the outer sampling tube 1. After removing the inner sampling tube 2, the controller of the rotating motor 21 is activated, causing the motor 21 to rotate, opening the sampling chamber 5 outwards, and allowing the sampled soft and glutinous foods to be removed for inspection.

[0040] During sampling, depending on the different internal layers of the soft and glutinous food, different adjustment knobs 7 are used to control the sliding plate 4 of the corresponding layer to slide outwards from the sliding groove 30, so that the corresponding sampling port 3 is in a closed or open state, thereby realizing layered sampling of different layers of the soft and glutinous food.
