[0031] Design of sample chamber 2 and pressing chamber 3: This design allows food samples to be pressed directly inside the instrument, reducing the risk of contamination during sample transfer, while also simplifying the operating process and improving detection efficiency.
[0032] The lower end of the pressing chamber 3 is fixedly connected to the filter screen 4 , and the bottom of the filter screen 4 is fixedly connected to the slot plate 6 . The slot plates 6 are provided in several groups, and the centers of the several groups of slot plates 6 are connected to the detection port 7 .
[0033] Configuration of the filter 4 and the slot plate 6: The filter 4 can effectively filter out solid matter such as pulp, allowing only juice to flow into the detection port 7, while the design of the slot plate 6 ensures that the juice can flow smoothly to the detection port 7, avoiding problems such as blockage and overflow.
[0034] The lower end of the detection port 7 is connected to the detection tube 8 , and the tail end of the detection tube 8 is fixedly mounted on the detection end of the detector 9 .
[0035] Integration of the detection port 7, the detection tube 8 and the detector 9: This integrated design allows the sample juice to flow directly from the pressing chamber 3 into the detector 9, eliminating intermediate links and reducing the possibility of sample contamination, while also improving the accuracy and speed of detection.
[0036] The sealing strip is fixedly mounted on the inner end of the sample chamber 2 , and the detection tube 8 passes through the inner end of the sealing strip.
[0037] Application of sealing strip: The sealing strip ensures the sealing between the sample chamber 2 and the pressing chamber 3, prevents juice leakage, and ensures a clean and hygienic testing environment.
[0038] The outer end of the sealing strip contacts the outer surface of the pressing chamber 3 , the upper end of the pressing chamber 3 is fixedly connected to the splash cover 5 , and the pressing chamber 3 is movably connected to the positioning seat 10 via a spring.
[0039] Provision of the splash-proof cover 5: The splash-proof cover 5 can effectively prevent the splashing of juice during the squeezing process, keep the instrument clean, and prevent the operator from coming into contact with the sample juice that may contain harmful substances.
[0040] The combination of the positioning seat 10 and the spring member: This design ensures that the pressing chamber 3 can be firmly pressed on the sample chamber 2, ensuring the effectiveness and consistency of the pressing process. The movable connection of the spring member also allows the pressing force to be properly adjusted to adapt to food samples of different hardness.
[0041] The upper end of the splash-proof cover 5 is slidably connected to the sliding rod 11 , the tail end of the sliding rod 11 is fixedly connected to the slider 13 , and the slider 13 slides left and right along the sliding groove 12 .
[0042] The center of the slider 13 is connected to the positioning rod 16 . The positioning rod 16 is fixed to the inner end of the sliding groove 12 . The linkage spring 15 is wrapped around the outer end of the positioning rod 16 .
[0043] Function of the linkage spring 15: The linkage spring 15 is wrapped around the outer end of the positioning rod 16 to provide a certain amount of damping and rebound for the movement of the sliding rod 11, making the squeezing process more stable and controllable.
[0044] The linkage mechanism of the sliding rod 11, the slider 13 and the sliding groove 12: This design allows the squeezing action to be completed by simply pushing and pulling the sliding rod 11. The operation is simple and intuitive. The movement of the slider 13 in the sliding groove 12 ensures the uniform distribution of the squeezing force.
[0045] The left end of the sliding rod 11 and the groove 14 penetrate each other.
[0046] Design of the groove 14: The groove 14 at the left end of the sliding rod 11 is used to facilitate the opening and closing of the splash-proof cover 5 after the sliding rod 11 moves to the right.
[0047] Example 1: Detection of pesticide content in strawberries
[0048] Step 1: Prepare the sample
[0049] Strawberries were randomly selected as test samples to ensure that there was no obvious damage or rot on the surface of the strawberries.
[0050] Step 2: Sample processing
[0051] Place the strawberries into the sample compartment 2 of the multifunctional food testing instrument, taking care not to exceed the maximum capacity of the sample compartment 2.
[0052] Step 3: Sample pressing
[0053] The squeezing chamber 3 is covered on the upper end of the strawberry by the positioning seat 10 and the spring member, and then the sliding rod 11 is pushed forward along the sliding groove 12 so that the squeezing chamber 3 squeezes the strawberry.
[0054] Step 4: Juice Collection
[0055] The juice produced after the strawberries are squeezed flows through the filter 4 into the groove plate 6 and then into the detection port 7.
[0056] Step 5: Detection and Analysis
[0057] The juice is connected to the detector 9 through the detection tube 8 for detection of pesticide content. The detector 9 automatically analyzes and displays the type and concentration of pesticide residues.
[0058] Step 6: Record the results
[0059] The pesticide content data displayed by the detector 9 is recorded for subsequent analysis and processing.
[0060] Example 2: Detection of pesticide content in cherries
[0061] Step 1: Sample selection
[0062] Cherries were randomly selected as test samples.
[0063] Step 2: Sample Preparation
[0064] After cleaning the cherries, remove the stems and place them in the sample chamber 2 of the testing instrument.
[0065] Step 3: Squeezing
[0066] Similarly, the pressing chamber 3 is placed on the cherries through the positioning seat 10 and the spring member, and then the sliding rod 11 is pushed to perform pressing.
[0067] Step 4: Juice Extraction
[0068] During the squeezing process, the cherry juice passes through the filter screen 4 and enters the groove plate 6, and finally flows into the detection port 7.
[0069] Step 5: Pesticide Testing
[0070] The juice sample is sent to the detector 9 through the detection tube 8 for rapid detection of pesticide content.
[0071] Step 6: Interpretation of results
[0072] After the detector 9 completes the analysis, it reads and records the pesticide residues in the cherries.
[0073] In these two examples, the efficiency and convenience of the multifunctional food testing instrument are fully demonstrated. By directly squeezing and testing small fruits, not only is the potential for contamination and error during sample transfer reduced, but testing efficiency and accuracy are also improved. This instrument is particularly suitable for rapidly detecting pesticide residues in agricultural products, ensuring food safety.
[0074] When the present application is in use: in order to facilitate the detection of pesticide content in food and ensure the stability of the test results, the food to be tested (such as blueberries) is placed in the sample chamber 2, and then the pressing chamber 3 connected by the positioning seat 10 and the spring member is covered on the upper end of the food to be tested, and the sliding rod 11 is pushed forward along the sliding groove 12. During this process, the pressing chamber 3 squeezes the food to be tested in the sample chamber 2 through the connection of the positioning seat 10, and the squeezed food squeezes out juice, which is moved to the detection port 7 through the groove plate 6 at the lower end of the filter screen 4, and is connected to the detector 9 through the detection tube 8 to perform pesticide content detection. During this process, there is no need to move the detected food through a test tube or a pipette to move the detected juice, which can greatly ensure the accuracy of the detection.
[0075] The above embodiments are only used to illustrate the present invention and are not intended to limit the technical solutions described in the present invention. Although this specification has described the present invention in detail with reference to the above embodiments, the present invention is not limited to the above specific implementation methods. Therefore, any modification or equivalent replacement of the present invention; and all technical solutions and improvements thereof that do not depart from the spirit and scope of the present invention are included in the scope of the claims of the present invention.
