Technical Field

[0001] This utility model relates to the field of food testing equipment technology, specifically a rapid food safety testing instrument. Background Technology

[0002] Food testing instruments are testing methods in the field of food safety. Rapid food safety testing instruments are a common and convenient type of food testing equipment. They quickly and quantitatively determine the moisture content of food by inserting probes into the sample. Grains and other foods containing a lot of moisture can lead to mold and bacteria growth, and testing is required before they are stored to ensure they meet standards. Handheld dual-probe detectors are a commonly used rapid moisture detector for grains and foods. They quickly measure the moisture content by inserting two probes into the sample and display the corresponding data on the main unit.

[0003] Existing portable dual-probe measuring instruments for food safety, while capable of rapid detection by inserting probes into food, still have the following shortcomings: the probes cannot be cleaned and protected after use; residue inevitably adheres to the outside of the probes after testing, affecting cleaning effectiveness and reuse; and the probe tips are directly exposed during transport, posing a significant risk of contamination and injury to personnel, resulting in unsatisfactory safety. Therefore, a rapid food safety testing instrument is proposed to address these problems. Utility Model Content

[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model. Example

[0017] like Figures 1 to 5 As shown, the rapid food safety testing instrument proposed in this embodiment includes a food testing instrument body, which includes a main body 1, two probes 11 fixed to the bottom of the main body 1, and a handle 12 fixedly connected to the top of the main body 1. A protective cleaning mechanism is installed on the main body 1. The protection and cleanup organizations include: The connecting plate 2 has a U-shaped structure in the middle and is connected to the bottom of the main body 1. Both sides of the top of the connecting plate 2 are fitted with rubber sleeves 231 that are movably sleeved on the outside of the corresponding probes 11. The top of the connecting plate 2 has two mounting holes that are respectively glued and fixed to the corresponding rubber sleeves 231. The baffle plate 22 is located below the connecting plate 2; The vertical guide lifting drive assembly is fixedly connected between the rear side of the connecting plate 2 and the top of the baffle plate 22. The vertical guide lifting drive assembly is used to drive the baffle plate 22 to move up and down. The baffle plate 22 moves up to expose the lower part of the two probes 11 so that personnel can insert them into the food for testing. The baffle plate 22 moves down to shield and protect the tip of the probe 11. The scraping and cleaning assembly consists of two sets, which are embedded and fixed on the top of the baffle plate 22. The two scraping and cleaning assemblies are respectively movably sleeved on the bottom of the corresponding probe 11. The scraping and cleaning assemblies are used to scrape and clean the residue adhering to the outside of the probe 11 after use when the baffle plate 22 moves down. The telescopic dirt-blocking rubber sleeve 23 consists of two sets and is fixedly connected between the connecting plate 2 and the baffle plate 22. The two telescopic dirt-blocking rubber sleeves 23 are respectively movably sleeved on the outside of the corresponding probe 11. The telescopic dirt-blocking rubber sleeve 23 is used to shield and protect the probe 11 when not in use, thereby reducing the risk of the probe 11 being accidentally contaminated or corroded during carrying.

[0018] It should be noted that the food testing instrument itself is a handheld dual-probe testing instrument.

[0019] Furthermore, the connecting plate 2 is bonded to the bottom of the main body 1 with strong adhesive.

[0020] Furthermore, such as Figure 2 and 3 As shown, the vertical guide lifting drive assembly includes a rectangular tube 21, a rectangular rod 212, a screw 213, and a small motor 211. The rectangular tube 21 is fixedly connected to the rear side of the connecting plate 2 and movably contacts the rear side of the main body 1. The rectangular rod 212 is slidably sleeved inside the rectangular tube 21 and fixedly connected to the top rear side of the baffle plate 22. The screw 213 is rotatably installed inside the rectangular tube 21. A bearing is fixedly connected to the upper inner side of the rectangular tube 21. The inner ring of the bearing is fixedly connected to the outer side of the screw 213, which serves to rotate the screw 213. The rectangular rod 212 is threaded onto the screw 213. The small motor 211 is fixedly installed at the top of the rectangular tube 21, and the output shaft of the small motor 211 is fixedly connected to the top of the screw 213. In this embodiment, the bottom end of the rectangular rod 212 is provided with a threaded hole that is threadedly connected to the screw 213. The threaded connection between the screw 213 and the threaded hole facilitates the upward and downward displacement of the rectangular rod 212 when the screw 213 rotates. A limit groove is provided on the right side of the rectangular rod 212, and a limit block that is slidably connected to the limit groove is fixedly connected to the inner wall of the right side of the rectangular tube 21, which serves to limit and prevent the rectangular rod 212 from detaching. In this embodiment, the rectangular tube 21, the rectangular rod 212, the screw 213 and the small motor 211 work together. The small motor 211 drives the screw 213 to rotate. The rotation of the screw 213 causes the rectangular rod 212 to slide upward or move downward within the rectangular tube 21. The rectangular rod 212 drives the baffle plate 22 to move upward or move downward.

[0021] Furthermore, such as Figure 3 and 4 As shown, the scraping cleaning assembly includes a wiping sponge 221 and a conical hard plastic scraper sleeve 222. Circular holes are provided on both sides of the top of the baffle plate 22. The wiping sponge 221 is glued and fixed in the corresponding circular holes and is in contact with the outer side of the probe 11. The conical hard plastic scraper sleeve 222 is fixedly connected in the corresponding circular holes and is located below the wiping sponge 221. The bottom inner side of the conical hard plastic scraper sleeve 222 is adapted to the corresponding probe 11. In this embodiment, by using the wiping sponge 221 and the conical hard plastic scraper sleeve 222 together, when the baffle plate 22 moves downward to cover and protect the bottom tip of the probe 11 again after use, the baffle plate 22 also drives the two wiping sponges 221 and the conical hard plastic scraper sleeve 222 to move downward. The conical hard plastic scraper sleeve 222 scrapes and cleans the residue adhering to the outside of the corresponding probe 11 downward, and the wiping sponge 221 further wipes and cleans the probe 11 after scraping. This achieves the effect of scraping and cleaning the residue adhering to the outside of the probe 11 in one go after use, improving the cleaning effect after use and reducing the phenomenon that residue residue affects subsequent use.

[0022] Furthermore, a lithium battery is fixedly installed at the bottom front side of the rectangular tube 21 and electrically connected to the small motor 211 via wires; It should be noted that the small motor 211 is equipped with a switch and is electrically connected to the lithium battery via wires. The preferred model of the small motor 211 is a dedicated motor for electric handheld devices, model 0816D009SR, which is suitable for the power output requirements of handheld devices. The technical solution of using the lithium battery to supply power via wires and cooperating with the switch to achieve forward and reverse opening and closing control is a mature technology that has been disclosed in this field. Its specific working principle and conventional wire electrical connection method will not be described in detail here.

[0023] This embodiment facilitates the scraping and cleaning of residues adhering to the outside of the probe 11 after use, and provides a safe shielding and protection for its tip. This reduces the possibility of residue residue affecting subsequent use, and also reduces the risk of the probe 11 tip being directly exposed to the outside during transport, making it susceptible to contamination and injury to personnel. This improves the cleaning effect and safety after use.

[0024] The usage method of this embodiment is as follows: When using this rapid food safety testing instrument, first start the small motor 211 in the forward direction to drive the screw 213 to rotate. The rotation of the screw 213 causes the rectangular rod 212 to slide upward inside the rectangular tube 21. The rectangular rod 212 drives the baffle plate 22 to move upward and compresses the two telescopic dirt-blocking rubber sleeves 23. As the baffle plate 22 moves upward, the lower part of the two probes 11 is exposed. Personnel can then hold the handle 12 and move it to insert the two probes 11 into the food for testing. The instrument can quickly remove the obstruction of the lower part of the probes 11 during use so that personnel can insert them for testing. After the test is completed and the probe is removed, the small motor 211 is started in reverse, which is the exact opposite of the forward start of the small motor 211. At this time, the baffle plate 22 moves downward and pulls the two telescopic dirt-blocking rubber sleeves 23 back to their original position. When the baffle plate 22 moves downward, it also drives the two wiping sponges 221 and the conical hard plastic scraper sleeve 222 to move downward. The conical hard plastic scraper sleeve 222 scrapes and cleans the residue adhering to the outside of the corresponding probe 11 downward. The wiping sponge 221 further wipes and cleans the probe 11 after it has been scraped clean. When the baffle plate 22 moves downward to its lowest position, it cleans the two probes. The bottom tip of the needle 11 is further shielded for protection, enabling the removal of residue adhering to the outside of the probe 11 after use. This improves the cleaning effect after use and reduces the possibility of residue residue affecting subsequent use. It also provides a comprehensive and safe shielding protection for the tip of the probe 11, reducing the risk of the tip being directly exposed to the outside and susceptible to contamination or injury during transport, thus improving safety. In addition, the retractable dirt-blocking sleeve 23 shields the outside of the probe 11 when not in use, reducing the risk of accidental contamination or corrosion during transport, further enhancing safety. Example

[0025] Reference Figure 6-7 As shown, this embodiment differs from Embodiment 1 in that: the connecting plate 2 is detachably connected to the bottom of the main body 1, the bottom of the main body 1 is fixedly connected to a nut 242, the top of the connecting plate 2 is provided with a hexagonal locking hole 24 that is movable and fits on the outside of the nut 242, the nut 242 is internally threaded with a knob bolt 241, and a rubber pad that is pressed and fixed to the bottom inner wall of the knob bolt 241 is bonded to it and makes tight contact with the bottom of the connecting plate 2.

[0026] This embodiment facilitates the disassembly and assembly of the protective cleaning mechanism from the main body 1 and the probe 11, which is convenient for subsequent inspection and maintenance work, and allows the protective cleaning mechanism to be reused when the main body 1 is damaged in the future, thus improving its practicality.

[0027] The method of use in this embodiment is as follows: The difference from Embodiment 1 is that it also has the following functions: In addition, the connecting plate 2 is positioned on the outside of the nut 242 by the hexagonal locking hole 24. The connecting plate 2 is pressed and locked by the knob bolt 241 into the nut 242. The locking work is performed by rotating the knob bolt 241 in the opposite direction to separate it from the nut 242. The connecting plate 2 can then be moved down to separate it from the nut 242, and the guard plate 22 will be moved down and gradually detached from the outside of the probe 11. This achieves the effect of conveniently disassembling and assembling the protective cleaning mechanism from the main body 1 and the probe 11, which facilitates subsequent inspection and maintenance work, and allows the protective cleaning mechanism to be recycled when the main body 1 is damaged in the future, thus improving its practicality.

[0028] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
