[0001] This invention relates to the field of food safety technology, specifically to a food safety testing instrument that prevents waste liquid residue. Background Technology

[0002] Food safety is closely related to people's health. With the development of technology, the number of additives in food has gradually increased. Some unscrupulous vendors add excessive amounts of harmful substances to food. Therefore, health and quality inspection departments use food safety testing instruments to detect additives in food to determine whether the food meets production standards. However, existing food safety testing instruments still have certain shortcomings in their use, such as: The utility model announcement number CN213600682U discloses a convenient food safety testing instrument. The instrument is practical, the main body of the safety testing instrument is easy to move, and the main body of the safety testing instrument has a protective function to prevent dust from falling into the main body of the safety testing instrument and to ensure the detection accuracy of the main body of the safety testing instrument. In the aforementioned document, the detector needs to be opened before using the main body of the safety detector to test the food. During the testing process, liquid needs to be placed inside the main body of the safety detector. After the main body of the safety detector is used, the liquid needs to be drained to facilitate the next use. However, the inside of the safety detector is smooth and flat. Directly draining the liquid inside can easily cause the waste liquid from the previous test to adhere to its inner surface, which can affect the test results of the next use and reduce the accuracy of the detector.

[0003] To address the aforementioned issues, there is an urgent need for innovative design based on the existing detector structure. Summary of the Invention

[0017] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0018] Example 1: This embodiment is an example Figures 1-4 As shown, in order to solve the problem of needing manual control during the stopping process of the detector, the working process of the automatic stopping structure is disclosed, which realizes the effect of automatic stopping of the detector. The specific content is as follows: The protective box 1 is equipped with a stop-start structure, and the stop-start structure achieves the effect of stopping the detector at any time by controlling the contact plate 25 to contact the ground. The following structure is internally provided with a sliding block 11 and a ball bearing 12. The sliding block 11 is slidably installed inside the fixed push rod 10, and the ball bearing 12 is nested inside the side of the sliding block 11 near the fixed push rod 10. A connecting rod 26 is fixedly installed on the outer side of the sliding block 11. A traction rope 14 is fixedly installed at the upper end of the sliding block 11. A support spring 13 is fixedly installed on the side of the sliding block 11 near the protective box 1. A contact plate 25 is fixedly installed at the end of the traction rope 14 away from the sliding block 11, and the contact plate 25 is slidably installed inside the mounting base 9. Two sets of telescopic rods 15 are fixedly installed at the upper end of the contact plate 25, and a return spring 16 is sleeved on the outside of the telescopic rod 15. The upper and lower ends of the return spring 16 are fixedly connected to the mounting base 9 and the contact plate 25, respectively, and two sets of return spring 16 and telescopic rod 15 are symmetrically arranged about the vertical central axis of the contact plate 25.

[0019] When using the food safety detector for preventing waste liquid residue, first place the detector in the desired working position. Before placing the detector in the desired position, the protective box 1 needs to be moved by the fixed push rod 10 and the connecting rod 26. The rollers will roll at the lower end of the mounting base 9. During the process of moving the detector by pushing the connecting rod 26, the connecting rod 26 will slide inside the fixed push rod 10. During the movement of the connecting rod 26, the ball bearings 12 inside the sliding block 11 will roll, thereby reducing the friction force on the connecting rod 26 during its movement. During the movement of the sliding block 11, it will compress the support spring 13 and cause the support spring 13 to contract. The sliding block 11 will also be pulled... Rope 14 pulls the contact plate 25 upwards inside the mounting base 9, allowing the mounting base 9 to separate from the ground. As the contact plate 25 moves upwards, the return spring 16 and the telescopic rod 15 retract. After the detector reaches the desired position, the connecting rod 26 can be stopped. At this time, the support spring 13 expands and pushes the sliding block 11 and the connecting rod 26 to their initial positions. Meanwhile, the telescopic rod 15 and the return spring 16 expand and push the contact plate 25 downwards. The protrusion at the lower end of the contact plate 25 then contacts the ground and prevents the detector from moving further. This completes the movement process of the detector. By automatically contacting the ground with the contact plate 25, the stability of the detector during the automatic stopping process is effectively improved.

[0020] Example 2: This embodiment is an example Figure 1 and Figures 5-6 As shown, in order to solve the problem of collisions during the movement of the detector 3, the working process of the buffer structure is disclosed, which achieves the effect of self-protection for the main body of the instrument. The specific content is as follows: A buffer structure is provided at the upper end of the placement plate 2. The buffer structure achieves the buffering and shock absorption effect on the main body of the instrument 3 by compressing the gas. The upper end of the placement plate 2 is fixedly installed with a fixing plate 17 and a mounting plate 19. A secondary airbag 20 is bonded to the side of the mounting plate 19 near the fixing plate 17, and two sets of main airbags 18 are bonded to the outside of the fixing plate 17. The main airbags 18 and the secondary airbags 20 are connected by air tubes. The mounting plate 19 and the secondary airbags 20 are symmetrically arranged in two sets about the vertical central axis of the fixing plate 17. A moving cylinder 24 is fixedly installed on the side of the mounting plate 19 near the fixed plate 17, and a fixed cylinder 22 is slidably installed on the outside of the moving cylinder 24. The fixed cylinder 22 is fixedly connected to the moving plate 21, and an air vent 23 is provided inside the fixed cylinder 22.

[0021] During the movement of the food safety testing instrument, there may be sudden braking or stopping. At this time, the main body 3 of the instrument will continue to move forward due to inertia. The main body 3 will drive the two sets of moving plates 21 to move. During the movement of the moving plates 21, they will compress the main airbag 18. After being compressed, the main airbag 18 will contract and deliver gas into the auxiliary airbag 20. The auxiliary airbag 20 will expand and prevent the moving plates 21 from continuing to move, thereby slowing down the movement speed of the main body 3. During the movement of the moving plates 21, the moving cylinder 24 will move into the fixed cylinder 22. At this time, the gas inside the fixed cylinder 22 and the moving cylinder 24 will be compressed and discharged through the air outlet 23, thereby further slowing down the movement speed of the moving plates 21. This completes the buffering process of the main body 3 of the instrument, thus effectively protecting the main body 3 of the instrument.

[0022] Example 3: This embodiment is an example Figure 1 and Figures 7-8 As shown, in order to solve the problem that additives adhering to the inside of the instrument body 3 after detection affect the next detection, the working process of the cleaning structure is disclosed, which realizes the effect of improving the detection accuracy of the instrument body 3. The specific content is as follows: The protective box 1 and the placement plate 2 fixedly installed inside the protective box 1; It also includes: the upper end of the placement plate 2 is slidably mounted with the instrument body 3, the lower end of the protective box 1 is fixedly mounted with the mounting base 9, and the outer side of the protective box 1 is fixedly mounted with the fixing push rod 10. The instrument body 3 is equipped with an automatic cleaning structure inside. The cleaning structure automatically cleans the inner surface of the instrument body 3 to reduce the residue of waste material on the inner surface, thereby reducing the impact of waste liquid on the detection results. The cleaning structure is equipped with a moving block 4, which is slidably installed inside the instrument body 3. The moving block 4 is located at the four corners of the instrument body 3, and a cleaning roller 5 and a drive roller 8 are rotatably installed between the two sets of moving blocks 4. There are three sets of cleaning rollers 5. A bevel gear 6 is sleeved on the outer side of the cleaning roller 5 and the drive roller 8, and the end of the drive roller 8 away from the bevel gear 6 is fixedly connected to the output shaft of the waterproof motor 7, and the waterproof motor 7 is located inside the moving block 4 around the bevel gear 6; Both the cleaning roller 5 and the drive roller 8 are rotatably connected to the moving block 4, and the two sets of bevel gears 6 are meshed together.

[0023] When using the instrument body 3, the protective case 1 and the flip-top of the instrument body 3 need to be opened sequentially. Then, the instrument body 3 can be used. During use, liquid needs to be added to the inside of the instrument body 3 to cause additives in the food to leach out. The liquid inside the instrument body 3 can then be drained for testing. When the instrument body 3 is full of liquid, the cleaning roller 5 and drive roller 8 are in a vacuum structure, causing them to float on top of the liquid. When the liquid inside the instrument body 3 is drained, the waterproof motor 7 needs to be activated to drive the drive roller 8. The moving roller 8 rotates, and during the rotation of the driving roller 8, it drives the cleaning roller 5 to rotate via the bevel gear 6. The cleaning roller 5, in turn, drives the other two sets of cleaning rollers 5 to rotate via the bevel gear 6. During the rotation of the cleaning roller 5 and the driving roller 8, the inner surface of the instrument body 3 is cleaned, thereby reducing the amount of additives adhering to the inner surface of the instrument body 3 and avoiding any impact on the next test results. Furthermore, the interior of the instrument body 3 can be repeatedly cleaned by adding pure water multiple times, ensuring the cleanliness of the interior of the instrument body 3, improving the accuracy of the instrument body 3's tests, and increasing the overall practicality.
