Description

Technical Field

[0001] The present invention relates to the field of food testing equipment, and particularly to a food testing sampling device. Background Art

[0002] In today's food industry, food safety is of utmost importance. With the improvement of people's living standards and the increasing attention to health, the requirements for food quality and safety are becoming increasingly stringent. As a key link in ensuring food safety, the accuracy and efficiency of food testing directly affect consumers' health as well as the reputation and market competitiveness of food enterprises. And sampling, the first step in food testing, plays a fundamental and decisive role in the entire testing process.

[0003] There are many problems with traditional food testing sampling methods. During manual sampling, there are significant differences in the technical levels and operating habits of operators, which makes it difficult to ensure the representativeness and accuracy of sampling. For example, when sampling bottled liquid food, if the operator fails to sample evenly at different positions deep inside the bottle and only takes samples near the bottle mouth, the samples taken cannot truly reflect the quality of the entire bottle of food, resulting in deviations in subsequent test results.

[0004] In terms of efficiency, traditional sampling methods are often extremely time-consuming and laborious. When a large number of food samples need to be tested, the method of sampling one by one manually not only consumes a large amount of manpower and time but also easily causes fatigue among operators due to long-term repetitive labor, further affecting the quality and efficiency of sampling. Moreover, traditional sampling devices have a single function and can usually only complete simple sampling operations, unable to meet the requirements of modern food testing for diverse functions.

[0005] In the cleaning process, traditional devices also have obvious deficiencies. Due to the lack of an effective automatic cleaning mechanism, it is difficult to clean sampling utensils in a timely and thorough manner during multiple sampling processes, which is extremely likely to cause cross-contamination between different samples. For example, when sampling for microbial testing of different batches of fruit juices, if the sampling tube is not cleaned thoroughly, the microorganisms in the previous batch of fruit juice may remain and mix into the samples of the next batch, resulting in serious errors in test results and misleading the judgment of food quality. Summary of the Invention

[0006] In view of the deficiencies of the prior art, the present invention provides a food testing sampling device, which solves the problems of insufficient sampling accuracy and representativeness, low efficiency, single function caused by manual operation, and easy cross-contamination due to the lack of an effective cleaning mechanism in traditional food testing sampling methods.

[0007] To achieve the above object, the present invention is realized by the following technical solutions: A food detection sampling device includes a box body. One side of the upper inner part of the box body is fixedly installed with a sampling chamber. In the middle of the bottom wall of the sampling chamber, a partition plate is fixedly installed, and the partition plate divides the inner bottom of the sampling chamber into a clear water bin and a sampling bin. On one side of the bottom of the sampling bin, a sampling funnel is fixedly installed. On the other side of the bottom of the sampling bin, a sampling pipe is fixedly installed, and the end of the sampling pipe extends to the outside of the box body. At the end of the sampling pipe, a sampling head is fixedly installed. A number of sampling holes are opened on the outer diameter of the sampling head. On one side of the lower inner part of the box body, a sampling port is opened. Inside the sampling port, a turntable is movably installed. On the surface of the turntable, a number of sampling bottle placement seats are fixedly arranged.

[0008] Preferably, a cross frame is movably installed in the middle of the sampling chamber. On both sides of the bottom end of the cross frame, fixing rods are fixedly installed. The bottom ends of the two fixing rods respectively extend into the clear water bin and the sampling bin and are fixedly installed with pistons. On both sides of the top end of the cross frame, pull rods are fixedly installed, and the ends of the pull rods all extend to the outside of the box body. The top parts of the pull rods are respectively fixedly installed at both ends of a handle. On both sides of the top end of the cross frame, close to the inner sides of the pull rods, return springs are fixedly installed, and the ends of the return springs are fixedly installed on the top wall of the sampling chamber.

[0009] Preferably, in the middle of the top end of the partition plate, a screw rod is movably installed. The end of the screw rod extends to the outside of the box body and is fixedly installed with an adjusting knob. On the outer diameter of the middle part of the screw rod, a blocking frame is threadedly connected. On both sides of the top wall of the sampling chamber, guide rods are fixedly connected, and the bottom ends of the guide rods respectively penetrate through both sides of the inside of the blocking frame.

[0010] Preferably, on the other side of the upper inner part of the box body, a cleaning water storage tank is fixedly installed. One side of the bottom of the cleaning water storage tank is connected to the inner bottom of the clear water bin through a water inlet pipe. At the bottom end of the clear water bin, a water outlet pipe is fixedly installed, and the end of the water outlet pipe is connected to the inside of the sampling pipe.

[0011] Preferably, a first one-way valve is fixedly installed on the outer diameter of the sampling pipe. A second one-way valve is fixedly installed on the outer diameter of the bottom of the sampling funnel. A third one-way valve is fixedly installed on the outer diameter of the middle part of the water inlet pipe. A fourth one-way valve is fixedly installed on the outer diameter of the middle part of the water outlet pipe.

[0012] Preferably, on the other side of the lower inner part of the box body, a waste material collection chamber is fixedly installed. On one side of the waste material collection chamber, a collection port is opened.

[0013] Preferably, a short column is fixedly installed in the middle of the top end of the turntable. An arc-shaped groove is formed on the outer surface of the short column. The middle of the bottom end of the piston is fixedly installed with a bending frame. The end of the bending frame extends above the short column and is fixedly installed with a sleeve. A plurality of grooves are evenly formed on the inner wall of the sleeve in a circumferential direction, and a limiting pin is installed in each groove through a pressing spring. The end of one of the limiting pins is movably arranged inside the arc-shaped groove.

[0014] The present invention provides a food detection sampling device, which has the following beneficial effects:

[0015] 1. The present invention integrates functions such as sampling, cleaning, sample temporary storage, and waste collection. Through a clever structural design, such as the layout of a sampling chamber, a clean water tank, a sampling bin, a cleaning water storage tank, and a waste collection chamber, the entire sampling process is compact and efficient, reducing the use of additional equipment and operation processes.

[0016] 2. During the sampling process of the present invention, the air pressure is changed by the up and down movement of the piston, realizing the automatic suction and discharge of liquid food, and the operation is simple and convenient. At the same time, after sampling is completed, the cleaning water in the clean water tank can automatically clean the sampling tube, effectively preventing cross-contamination caused by multiple samplings and improving the accuracy of the detection results.

[0017] 3. By rotating the adjustment knob of the present invention, the screw can be driven to rotate. Then, under the limiting action of the guide rod, the blocking frame moves up and down, thereby changing the upward movement amount of the cross frame and realizing flexible adjustment of the sampling amount each time to meet different detection requirements.

[0018] 4. During the movement of the cross frame and the piston of the present invention, through the cooperation of the bending frame, the sleeve, the limiting pin and the arc-shaped groove on the short column, the turntable can be automatically rotated by a certain angle to realize automatic bottle changing, improving the sampling efficiency and reducing the manual operation steps.

Detailed implementation manner

[0025] The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0026] Embodiment:

[0027] Please refer to the attached Figure 1 - attached Figure 5 , the embodiment of the present invention provides a food detection sampling device, as Figure 1As shown in the figure, it includes a box body 1. The box body 1 serves as the main structure of the entire device, providing installation and support space for internal components. Its internal space is reasonably planned to achieve the coordinated operation of various functions. On one side of the upper inner part of the box body 1, a sampling chamber 2 is fixedly installed. The sampling chamber 2 is one of the core areas of the entire sampling operation. In the middle of the bottom wall of the sampling chamber 2, a partition plate 3 is fixedly installed. The partition plate 3 is like a precise space divider, dividing the inner bottom part of the sampling chamber 2 into a clear water tank 4 and a sampling tank 5. The clear water tank 4 is used to store cleaning water, and after sampling, it is used to clean the sampling pipe 7 to prevent cross-contamination. The sampling tank 5 is used to temporarily store the samples extracted from the food to be tested, preparing for the subsequent sample transfer. On one side of the bottom of the sampling tank 5, a sampling funnel 6 is fixedly installed. The sampling funnel 6 has a funnel-shaped structure. Its large-diameter end is connected to the bottom of the sampling tank 5, and its small-diameter end is used to guide the sample to accurately fall into the sampling bottle below. On the other side of the bottom of the sampling tank 5, a sampling pipe 7 is fixedly installed. The sampling pipe 7 is the channel connecting the sampling head 8 and the sampling tank 5. Its end extends to the outside of the box body 1, facilitating the operator to hold it for sampling operations. At the end of the sampling pipe 7, a sampling head 8 is fixedly installed. The sampling head 8 is in direct contact with the liquid food to be tested. A number of sampling holes 9 are opened on its outer diameter. These sampling holes 9 are evenly distributed on the outer circumference of the sampling head 8, ensuring that the liquid food samples can be collected comprehensively during sampling. On one side of the lower inner part of the box body 1, a sampling port 29 is opened. The sampling port 29 provides space for the installation of the turntable 30 and the placement of samples. Inside the sampling port 29, a turntable 30 is movably installed. The turntable 30 can rotate around the central axis inside the sampling port 29. On the surface of the turntable 30, a number of sampling bottle placement seats 31 are fixedly arranged. These sampling bottle placement seats 31 are evenly distributed on the surface of the turntable 30 at a certain interval, used for placing sampling bottles. And each sampling bottle placement seat 31 is provided with an elastic band, which can be adjusted according to different sizes of sampling bottles to firmly fix the sampling bottle on the placement seat, avoiding the sampling bottle from tipping or shaking during the sampling process and ensuring the stability of sampling.

[0028] In this embodiment, a cross-frame 10 is movably installed in the middle part of the sampling chamber 2. The cross-frame 10 plays a key role in connection and transmission. Fixed rods 11 are fixedly installed on both sides of the bottom end of the cross-frame 10. The two fixed rods 11 are like two solid transmission columns, and their bottom ends respectively extend into the inside of the clear water tank 4 and the sampling tank 5 and are fixedly installed with pistons 12. The pistons 12 are in close fit with the inner walls of the clear water tank 4 and the sampling tank 5 and can move up and down in the tanks under the drive of the fixed rods 11. By changing the air pressure in the tanks, the suction and discharge of the liquid are realized. Pulling rods 13 are fixedly installed on both sides of the top end of the cross-frame 10. The pulling rods 13 connect the cross-frame 10 with the handle 14, and their ends extend to the outside of the box body 1, facilitating the operator to operate the cross-frame 10 outside the box body 1. The top parts of the pulling rods 13 are respectively fixedly installed at both ends of the handle 14. The operator only needs to hold the handle 14 and perform the up and down pulling operation to drive the cross-frame 10 to move through the pulling rods 13. Reset springs 15 are fixedly installed at the inner sides of both sides of the top end of the cross-frame 10 close to the pulling rods 13. The reset springs 15 have good elasticity, and their ends are fixedly installed on the top wall of the sampling chamber 2. When the operator releases the handle 14, the reset springs 15 can provide a downward elastic force to quickly lower the cross-frame 10 to reset and prepare for the next sampling operation.

[0029] Further, a screw rod 16 is movably installed in the middle of the top end of the partition plate 3. The end of the screw rod 16 extends to the outside of the box body 1 and is fixedly installed with an adjusting knob 17. The operator can drive the screw rod 16 to rotate by rotating the adjusting knob 17. A blocking frame 18 is threadedly connected to the outer diameter of the middle part of the screw rod 16. When the screw rod 16 rotates, the blocking frame 18 will move up and down along the axial direction of the screw rod 16 due to the action of the thread. Guide rods 19 are fixedly connected to both sides of the top wall of the sampling chamber 2. The guide rods 19 play a role in limiting and guiding. Their bottom ends respectively penetrate through both sides of the inside of the blocking frame 18. The guide rods 19 ensure that the blocking frame 18 can only move up and down along the direction of the guide rods 19 and will not rotate or shift, thus ensuring the accuracy and stability of the blocking frame 18 when adjusting the upward movement amount of the cross-frame 10. By rotating the adjusting knob 17, the position of the blocking frame 18 is changed, and then the upward moving cross-frame 10 can be blocked at different positions to realize the flexible adjustment of the sampling amount each time and meet different detection requirements.

[0030] Further, on the other side of the upper inner part of the box body 1, a cleaning water storage tank 20 is fixedly installed. The cleaning water storage tank 20 is used to store a large amount of cleaning water, providing a water source guarantee for the cleaning link of the whole device. One side of the bottom of the cleaning water storage tank 20 is connected to the inner bottom of the clean water tank 4 through a water inlet pipe 21. When the piston 12 moves upward and the air pressure in the clean water tank 4 decreases, the cleaning water in the cleaning water storage tank 20 will flow into the clean water tank 4 along the water inlet pipe 21 under the action of the atmospheric pressure. A water outlet pipe 22 is fixedly installed at the bottom end of the clean water tank 4. The water outlet pipe 22 is the channel for the cleaning water to flow from the clean water tank 4 to the sampling pipe 7, and its end is connected to the inside of the sampling pipe 7. After the sampling is completed, the piston 12 descends, the air pressure in the clean water tank 4 increases, and the cleaning water will flow into the sampling pipe 7 along the water outlet pipe 22 to clean the inside of the sampling pipe 7, effectively preventing cross-contamination caused by multiple samplings.

[0031] Further, a first one-way valve 23 is fixedly installed on the outer diameter of the sampling pipe 7. The first one-way valve 23 only allows the liquid to flow from the sampling head 8 to the sampling chamber 5, preventing the liquid from flowing back during the sampling process. A second one-way valve 24 is fixedly installed on the outer diameter of the bottom of the sampling funnel 6. The second one-way valve 24 only allows the liquid to flow from the sampling funnel 6 to the sampling bottle below, preventing the sample from flowing back to the sampling funnel 6. A third one-way valve 25 is fixedly installed on the outer diameter of the middle part of the water inlet pipe 21. The third one-way valve 25 ensures that the cleaning water can only flow from the cleaning water storage tank 20 to the clean water tank 4, preventing the water in the clean water tank 4 from flowing back to the cleaning water storage tank 20. A fourth one-way valve 26 is fixedly installed on the outer diameter of the middle part of the water outlet pipe 22. The fourth one-way valve 26 ensures that the cleaning water can only flow from the clean water tank 4 to the sampling pipe 7, preventing the cleaned sewage from flowing back to the clean water tank 4. The design of these one-way valves ensures the one-way flow of the liquid, enabling the whole sampling and cleaning process to proceed smoothly according to the predetermined process and preventing pollution and operation errors caused by the liquid flowing back.

[0032] Further, a waste material collection chamber 27 is fixedly installed on the other side of the lower inner part of the box body 1. The waste material collection chamber 27 is used to collect the sewage and other waste generated during the sampling process. A collection port 28 is opened on one side of the waste material collection chamber 27. After the sampling is completed, the sampling head 8 is inserted into the collection port 28, and the wastewater generated by cleaning the sampling pipe 7 will flow into the waste material collection chamber 27 through the collection port 28 for centralized collection and treatment.

[0033] Furthermore, a short column 32 is fixedly installed in the middle of the top end of the turntable 30. The short column 32 is one of the key components for realizing the automatic rotation of the turntable 30. An arc-shaped groove 33 is formed on the outer surface of the short column 32. The shape and size of the arc-shaped groove 33 match those of the limit pin 37. A bent frame 34 is fixedly installed in the middle of the bottom end of the piston 12. The bent frame 34 transmits the movement of the piston 12 to the sleeve 35. The end of the bent frame 34 extends above the short column 32 and a sleeve 35 is fixedly installed. The sleeve 35 is sleeved outside the short column 32. A plurality of grooves are evenly formed in a circle on the inner wall of the sleeve 35. Limit pins 37 are connected and installed in the grooves through compression springs 36. The end of one side of the limit pin 37 is movably arranged inside the arc-shaped groove 33. When the handle 14 drives the cross frame 10 and the piston 12 to move upward, the bent frame 34 will drive the sleeve 35 to move upward. The limit pin 37 in the sleeve 35 slides along the arc-shaped groove 33 on the short column 32. Due to the special shape of the arc-shaped groove 33, the short column 32 will be driven to rotate, thereby driving the turntable 30 to rotate by a certain angle until the limit pin 37 disengages from the arc-shaped groove 33. At this time, the short column 32 and the turntable 30 stop rotating, just aligning the opening of the next sampling bottle with the bottom of the sampling funnel 6. After the handle 14 is released again, the sleeve 35 descends, and all the limit pins 37 in the sleeve 35 will be pressed into the grooves on the inner diameter of the sleeve 35 until one of the limit pins 37 is re-locked into the arc-shaped groove 33 through the compression spring 36, realizing continuous bottle-changing sampling work, improving the sampling efficiency, and reducing the manual operation steps.

[0034] Working principle: first, put the sampling bottles into the sampling bottle placement seat 31 on the turntable 30 in turn. The sampling bottle placement seat 31 is provided with an elastic ring to fix the sampling bottle. Then, pick up the sampling tube 7 with one hand, insert the sampling head 8 into the liquid food to be sampled, and pull the handle 14 upward with the other hand. When the handle 14 moves upward, it will drive the two pull rods 13 to move upward, and drive the cross frame 10 to move upward. The upwardly moved cross frame 10 drives the pistons 12 in the clean water chamber 4 and the sampling chamber 5 to move upward through the fixed rod 11. When the piston 12 moves upward, the air pressure in the clean water chamber 4 and the sampling chamber 5 decreases, and the external atmospheric pressure opens the first one-way valve 23 and the third one-way valve 25, and the liquid food will pass through the sampling valve on the outer diameter of the sampling head 8. The sampling hole 9 enters into the sampling tube 7, and enters into the sampling chamber 5 along the sampling tube 7, and finally falls into the sampling funnel 6. The cleaning water in the cleaning water storage tank 20 will enter into the clean water chamber 4 along the water inlet pipe 21 until the cross frame 10 is blocked by the blocking frame 18 and cannot move up further. Then the sampling head 8 is taken out of the liquid food and inserted into the collecting port 28, and then the handle 14 is released. Under the action of the reset spring 15, the cross frame 10 descends and resets. At this time, the air pressure in the clean water chamber 4 and the sampling chamber 5 increases, and the external atmospheric pressure opens the second one-way valve 24 and the fourth one-way valve 26, so that the liquid food in the sampling funnel 6 is discharged into the sampling bottle, completing the sampling work. At the same time, the cleaning in the clean water chamber 4 Water flows into the sampling tube 7 along the outlet pipe 22 to clean the inside of the sampling tube 7, which can prevent cross contamination caused by multiple samplings. The waste water generated by the cleaning enters the waste collection chamber 27, and then the above operation is repeated, and the sampling head 8 is inserted into the next liquid food to be sampled again, and the handle 14 is pulled up again. In the process of driving the cross frame 10 and the piston 12 to move upward, the handle 14 will also drive the bending frame 34 to move upward, and the bending frame 34 drives the sleeve 35 to move upward. The limit pin 37 in the sleeve 35 slides along the arc groove 33 on the short column 32, driving the short column 32 to rotate, thereby driving the turntable 30 to rotate a certain angle until the limit pin 37 is disengaged from the arc groove 33. At this time, the short column 3 2 and the turntable 30 stop rotating, just aligning the opening of the next sampling bottle with the bottom of the sampling funnel 6, and after loosening the handle 14 again, the sleeve 35 descends, and all the limit pins 37 in the sleeve 35 are pressed into the grooves on the inner diameter of the sleeve 35, until one of the limit pins 37 is re-engaged in the arc groove 33 by the compression spring 36, and the bottle sampling is continuously changed in the direction. When the sampling amount needs to be adjusted, the adjusting knob 17 is rotated, and the adjusting knob 17 drives the screw rod 16 to rotate. Under the limiting action of the guide rod 19, the blocking frame 18 is driven to move up and down, so that the blocking frame 18 can block the upwardly moving cross frame 10 at different positions, and the sampling amount each time is changed by changing the upward movement of the cross frame 10.
