Description

Technical Field

[0001] This utility model relates to the field of rapid detection instruments, specifically to a rapid detection instrument for food bacteria. Background Technology

[0002] The food bacteria rapid detection instrument is used to quickly detect pathogenic bacteria, hygiene indicator bacteria and other bacteria in food, and the results are available in minutes to hours. It is a device used to assess food safety, freshness and hygiene, and is suitable for production, distribution and other scenarios.

[0003] Utility model patent CN209979602U discloses a rapid bacterial detection device for food, including a detector fixedly connected inside a detection chamber. The detection chamber has a tightly connected detection door at its front end, a handle fixedly connected to the upper end of the detection door, an observation window tightly installed below the handle, and an adsorption block fixedly installed above the observation window. A vertical rod is tightly connected above the detector, and a horizontal rod is connected to the top of the vertical rod. This rapid bacterial detection device for food features a detection chamber with ventilation openings. An ultraviolet lamp and a ventilation motor are fixedly installed inside the detection chamber to create a detection environment with fewer bacteria, reducing the deviation of the detection results and decreasing the workload for testing personnel, thus improving detection efficiency. A refrigerated box is included to facilitate the storage of food samples, prevent spoilage and bacterial growth, and improve the accuracy of subsequent detection results.

[0004] Regarding the aforementioned technologies, the inventors have discovered the following drawbacks: When storing test samples, existing rapid testing instruments lack a dedicated sample fixing and classification storage structure, and can only directly stack the samples inside the refrigerator. When users need to retrieve samples from the refrigerator, the disorderly stacking of samples makes it difficult to quickly and accurately locate and retrieve the target sample. This not only seriously affects the efficiency of the testing work, but also causes many inconveniences in actual operation. Utility Model Content

[0005] To address the aforementioned shortcomings of existing technologies, this invention provides a rapid food bacteria detection instrument that effectively solves the problem of the lack of a dedicated sample fixation and classification storage structure in existing technologies. When users need to retrieve samples from a refrigerator, the disorderly stacking of samples makes it difficult to quickly and accurately locate and retrieve the target sample, which seriously affects the efficiency of the detection work and causes inconvenience in actual operation.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] This utility model provides a rapid food bacteria detector, comprising: a rapid detector body, a refrigerator, a sealing plate, and a control panel. The refrigerator is installed on one side of the rapid detector body, the sealing plate is located on the front of the refrigerator, and the control panel is installed on the top of the rapid detector body. The refrigerator is equipped with a storage sliding assembly, which includes a fixed plate. Several fixed plates are arranged at equal intervals. A limiting groove is formed on the top of the fixed plate, and a limiting plate is movably connected inside the limiting groove. An aluminum alloy storage column is installed on the inner side of the limiting plate, and a slider is installed on the bottom of the fixed plate. A sliding plate is slidably connected to the bottom of the slider.

[0008] A connecting and fixing assembly is installed on the back of the inner wall of the refrigerator. The connecting and fixing assembly includes a connecting plate. A fixing groove is installed on the front of the connecting plate. An electromagnetic block is installed on the back of the inner wall of the fixing groove. A movable plate is provided on the front of the electromagnetic block. The front of the movable plate is installed with the back of the fixing plate. The electromagnetic block and the movable plate are magnetically connected. A sliding plate is installed on the front of the connecting plate. A damping spring is installed on the front of the electromagnetic block. The other end of the damping spring is installed with the back of the movable plate.

[0009] With the above scheme, several equidistant fixed plates in the storage sliding assembly can classify and store samples. The limiting groove and the limiting plate work together to restrict the position of the aluminum alloy storage column. The slider and the sliding plate allow the fixed plate to slide, which facilitates the storage and retrieval of samples. The electromagnetic block in the connecting fixed assembly is magnetically connected to the moving plate, which can fix the fixed plate. When it is necessary to remove the sample, the electromagnetic block is de-energized and loses its magnetism, and the fixed plate can be moved to remove the sample. After the sample is removed, the fixed plate can be reset and pushed.

[0010] Furthermore, a connecting groove is provided on the front side of the sealing plate, the front side of the surface of the fixing plate is located on the inner wall of the connecting groove, a heat insulation plate is installed on the front side of the fixing plate, a moving rod is installed at the bottom of the front side of the fixing plate, and the front side of the moving rod passes through the heat insulation plate and extends to the front side of the heat insulation plate.

[0011] The above solution provides a channel for the sliding of the fixed plate, the insulation plate reduces the loss of temperature inside the refrigerator and maintains a low temperature environment inside the refrigerator, and the movable rod allows the user to manually pull the fixed plate to slide in the connecting groove, so that sample storage can be operated without opening the sealing plate, further reducing temperature loss and ensuring the sample storage environment.

[0012] Furthermore, a proximity sensor is installed on the back of the inner wall of the fixing groove. The proximity sensor is electrically connected to a controller via a wire. The controller is electrically connected to a time relay via a wire. The controller is installed on the top of the refrigerator. The time relay is installed on the top of the refrigerator. An indicator light is installed on the top of the refrigerator. The controller is electrically connected to the indicator light via a wire.

[0013] With the above solution, the proximity sensor can detect whether the fixing plate is in place. After the fixing plate is moved out, the proximity sensor can send a signal to the controller. After receiving and processing the signal, the controller controls the time relay to set a relevant time. If the fixing plate is not reset within the time set by the time relay, it will be detected by the proximity sensor. The time relay will send a signal to the controller. After receiving and processing the signal, the controller will activate the indicator light to remind the user to avoid the loss of cold air due to the fixing plate not being reset for a long time.

[0014] Furthermore, a strong magnetic block is embedded in the bottom of the inner wall of the limiting groove. Several strong magnetic blocks are arranged at equal intervals, and the strong magnetic blocks are magnetically connected to the limiting plate.

[0015] Through the above scheme, the strong magnetic block in the limiting groove generates a magnetic attraction to the limiting plate, so that the limiting plate stably fixes the aluminum alloy storage column, preventing it from shaking or shifting during storage, and ensuring the stability and safety of sample storage.

[0016] Furthermore, a protective cover is threaded onto the top of the surface of the aluminum alloy storage column, and an ultraviolet lamp is installed on the outer side of the inner wall of the refrigerator. The ultraviolet lamp is electrically connected to the controller via a wire, and a disinfection box is slidably connected to one side of the bottom front of the sealing plate. The disinfection box is used to disinfect the removed protective cover.

[0017] The above solution prevents samples from being contaminated by the protective cover, disinfects the inside of the refrigerator with ultraviolet light to ensure a hygienic storage environment, and disinfects the removed protective cover, thus improving the hygiene of sample storage.

[0018] Furthermore, a transparent plate is installed on the top of the protective cover, a label is inserted between the transparent plate and the protective cover, and a flow groove is opened on the outer side of the fixing plate.

[0019] With the above solution, the transparent plate on the protective cover works in conjunction with the label to facilitate the user's identification and marking of the sample, allowing for quick location of the target sample. The flow groove on the outside of the fixed plate helps the air to circulate inside the refrigerator, making the temperature distribution inside the refrigerator more uniform and beneficial for sample preservation.

[0020] Furthermore, a limiting block is installed on the outer side of the bottom front of the refrigerator box, the limiting block supports the bottom of the sealing plate, and a pressing plate is movably connected to the top of the sealing plate.

[0021] The above solution provides support for the bottom of the sealing plate, ensuring accurate installation. The clamping plate is movably connected to the top of the sealing plate, applying pressure to the sealing plate to ensure a tight fit between the sealing plate and the refrigerator, thereby enhancing the refrigerator's sealing performance, preventing cold air leakage, and guaranteeing the refrigeration effect.

[0022] Furthermore, a return spring is installed on the rear side of the bottom of the pressing plate, and an installation groove is opened on the outer side of the top of the refrigerator box. The other end of the return spring is installed on the bottom of the inner wall of the installation groove.

[0023] With the above solution, the return spring is installed in the mounting groove on the rear side of the bottom of the pressure plate. When the sealing plate is closed, the return spring is compressed and stores elastic potential energy, providing a clamping force to make the sealing plate seal more tightly.

[0024] Beneficial effects

[0025] The technical solution provided by this utility model has the following advantages compared with the known prior art:

[0026] I. This utility model, by setting up storage sliding components, connecting and fixing components, etc., and through the cooperation of the fixing plate with the limiting groove, limiting plate, slider, and sliding plate, as well as the magnetic connection between the electromagnetic block and the moving plate, enables the fixing plate to classify and store samples and conveniently access them through sliding and magnetic fixation. This achieves the effect of the device being able to quickly and accurately locate and efficiently retrieve the selected samples through an orderly storage structure.

[0027] II. This utility model incorporates components such as a proximity sensor, a controller, a time relay, and indicator lights. By detecting the position of the fixed plate through the proximity sensor and exchanging signals with the controller and time relay, the indicator lights can provide timely reminders to warn the fixed plate that has not been reset in time. This achieves the goal of preventing excessive loss of cold air in the refrigerator and thus avoiding a large temperature difference.

[0028] Third, this utility model, by setting up components such as strong magnetic blocks, limiting plates, aluminum alloy storage columns, ultraviolet lamps, and disinfection boxes, uses the magnetic adsorption of the limiting plates by the strong magnetic blocks and the synergistic disinfection effect of the ultraviolet lamps and disinfection boxes to enable the aluminum alloy storage columns to safely store samples in a stable and sterile environment. This allows the device to safely protect the screened samples through multiple protective measures. Attached Figure Description

An ultraviolet lamp 16 is installed on the outer side of the inner wall of refrigerator 2. 16 is electrically connected to the controller 11 via a wire. A disinfection box 17 is slidably connected to one side of the bottom front of the sealing plate 3. The disinfection box 17 is used to disinfect the removed protective cover 15. A transparent plate 18 is installed on the top of the protective cover 15. A label 19 is inserted between the transparent plate 18 and the protective cover 15. A flow groove 20 is opened on the outer side of the fixing plate 51. A limit block 21 is installed on the outer side of the bottom front of the refrigerator 2. The limit block 21 supports the bottom of the sealing plate 3. A pressing plate 22 is movably connected to the top of the sealing plate 3. A return spring 23 is installed on the rear side of the bottom of the clamping plate 22. An installation groove 24 is opened on the outer side of the top of the refrigerator box 2. The other end of the return spring 23 is installed on the bottom of the inner wall of the installation groove 24. The sealing plate 3, together with the clamping plate 22 and the spring, achieves the sealing of the refrigerator box 2. The proximity sensor 10, controller 11, time relay 12 and indicator light 13 monitor the status of the fixing plate 51 in real time and provide early warning. The proximity sensor 10, controller 11, time relay 12 and indicator light 13 are existing technologies. The ultraviolet lamp 16 is an existing technology.

[0041] Working principle: After the power is turned on, the controller 11 automatically triggers the ultraviolet lamp 16 to start, pre-disinfecting the inside of the refrigerator 2 and killing the bacteria remaining in the refrigerator 2. At the same time, the removed protective cover 15 is placed into the disinfection box 17 on the front of the sealing plate 3. The ultraviolet lamp 16 inside the refrigerator 2 sterilizes the protective cover 15, ensuring a sterile sample storage environment and preparing for subsequent sample storage.

[0042] First, pull the moving rod 9. The slider 55 at the bottom of the fixed plate 51 slides into the sliding plate 56 inside the refrigerator 2, pulling the empty fixed plate 51 out of the connecting slot 7 on the front of the refrigerator 2 to a suitable position. Then, remove the aluminum alloy storage column 54 from the limiting slot 52, and insert the food sample tube to be tested into the aluminum alloy storage column 54. Tighten the protective cap 15, which is threadedly connected to the aluminum alloy storage column 54. After filling in the sample information on the label 19, insert it below the transparent plate 18 at the top of the protective cap 15 for subsequent identification. Place the aluminum alloy storage column 54 containing the sample into the limiting slot 52 at the top of the fixed plate 51, causing the limiting plate 53 to engage with the limiting slot 52. Utilize the magnetic attraction of the strong magnet 14 embedded at the bottom of the inner wall of the limiting slot 52 to the limiting plate 53. The aluminum alloy storage column 54 is fixed to prevent it from shaking. The fixing plate 51 is pushed along the slide plate 56 into the refrigerator 2. Due to the protection of the aluminum alloy storage column 54 and the protective cover 15, the bacteria in the sample tube will not be sterilized by the ultraviolet lamp 16. When the moving plate 64 on the back of the fixing plate 51 moves to the back of the inner wall of the refrigerator 2, the controller 11 powers the electromagnetic block 63. The electromagnetic block 63 and the moving plate 64 are magnetically connected to attract the moving plate 64, and the fixing plate 51 is firmly fixed to the back wall of the refrigerator 2. At this time, the proximity sensor 10 detects that the fixing plate 51 is in place and does not trigger an alarm signal. The low temperature environment inside the refrigerator 2 is maintained by the refrigeration system to preserve the sample. The flow groove 20 opened on the outside of the fixing plate 51 promotes air circulation inside the box and ensures uniform temperature.

[0043] When a sample needs to be retrieved, the controller 11 first de-energizes the electromagnetic block 63, causing it to lose its magnetism and releasing the lock on the fixing plate 51. At this time, the damping spring 65 is in a stretched state, and its internal damping medium generates resistance through the throttling orifice, slowing down the reset speed of the fixing plate 51. The operator can smoothly pull out the fixing plate 51 using the moving rod 9 without worrying about immediate rebound causing hand pinching or sample shaking. The target aluminum alloy storage column 54 can be directly removed. After removing the sample by rotating the protective cover 15 in the reverse direction, the fixing plate 51 is pushed back to reset, and the electromagnetic block 63 is re-energized and locked. Subsequently... The protective cover 15 is placed in the disinfection box 17 for disinfection. The aluminum alloy storage column 54 is moved into the refrigerator 2. Since the protective cover 15 is not connected to its top at this time, the ultraviolet light generated by the ultraviolet lamp 16 will directly sterilize the inside of the aluminum alloy storage column 54. If the user does not reset in time, after the time relay 12 has been preset for a period of time, the proximity sensor 10 sends a signal to the controller 11 because it does not detect the fixing plate 51. The controller 11 triggers the indicator light 13 to flash and alarm, reminding the user to close the fixing plate 51 to prevent the temperature inside the refrigerator 2 from rising.

[0044] When closing the refrigerator 2, the sealing plate 3 is pressed down by the pressure plate 22 at the top. The return spring 23 installed at the bottom rear side of the pressure plate 22 is compressed and generates elastic force, so that the sealing plate 3 fits tightly with the refrigerator 2. Together with the limit block 21 installed on the outer side of the bottom front of the refrigerator 2, the bottom of the sealing plate 3 is supported, ensuring the airtightness of the refrigerator and reducing cold air leakage. When the refrigerator 2 needs to be opened as a whole, the pressure plate 22 is manually lifted to release the seal. After the operation is completed, it is pressed down again to reset.

[0045] The above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions will not cause the essence of the corresponding technical solutions to deviate from the protection scope of the technical solutions of the embodiments of this utility model.
