Description

Technical Field

[0001] This disclosure relates to the field of microbial detection technology, and in particular to a beef microbial safety detection device. Background Technology

[0002] There are various methods for microbial detection, mainly including the following: Culture method: This involves inoculating samples onto a culture medium suitable for the growth of specific microorganisms and observing colony formation to identify and count microorganisms. This method can provide information on the growth characteristics of microorganisms, but it is time-consuming and cannot detect microorganisms that are difficult to culture. Biochemical test: This method utilizes the characteristics of microbial metabolites to determine the type of microorganism through a series of chemical reactions. Immunological methods: These include techniques such as enzyme-linked immunosorbent assay (ELISA), immunofluorescence, and immunoprecipitation. They utilize the principle of specific antibody-antigen binding to rapidly detect the presence of specific microorganisms in a sample. Molecular biology techniques: These include polymerase chain reaction (PCR), real-time quantitative PCR, and gene sequencing. These techniques can directly amplify or detect specific DNA or RNA sequences from samples, achieving highly sensitive and specific microbial detection. Microbial sensors: These utilize the specific interaction between biomolecules and target analytes to detect microorganisms through changes in physical or chemical signals. Flow cytometry: This method uses a laser beam to irradiate single cells and identifies and counts microorganisms based on the scattering of the laser light and the fluorescence signal.

[0003] During the production and processing of beef, it is necessary to test for microorganisms to prevent spoilage. For example, the patent with publication number CN223837426U discloses a safety testing device for microorganisms in beef. The device detects microorganisms in beef by fixing a testing instrument on a support arm. However, because the testing method is directly exposed to the air, the external environment can easily affect the test results, resulting in a decrease in the accuracy of the test. Furthermore, when the number of microorganisms in the beef is small, errors can easily occur, leading to situations where microorganisms are not detected. Summary of the Invention

[0021] Embodiments of this disclosure are described in detail below, examples of which are illustrated in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are used only to explain this disclosure, and should not be construed as limiting this disclosure. Rather, embodiments of this disclosure include all variations, modifications, and equivalents falling within the spirit and scope of the appended claims.

[0022] like Figures 1 to 13 As shown in the figure, this disclosure proposes a beef microbial safety testing device, comprising: a base 101, a top cover 103 slidably fitted on the base 101, a rotating plate 202 rotatably fitted inside the base 101, a placement rack 203 fixed on the rotating plate 202, a wiring structure installed between the placement rack 203 and the base 101, multiple placement slots 206 and multiple auxiliary slots 207 opened inside the placement rack 203, and a water spray head fixed inside the auxiliary slots 207; multiple test tubes 301, the test tubes 301 being snapped and fixed inside the placement slots 206, a support frame 302 placed inside the test tubes 301, multiple heating tubes 314 installed around the periphery of the test tubes 301, and the top of the test tubes 301 being snapped and fixed. A piston cover 304 is fixed, and a sealing ball 306 is rotatably fitted inside the piston cover 304. A transmission structure is installed inside the piston cover 304. The detection structure includes a probe 701, on which a biochemical sensor and a cell sensor are mounted. A lower pressure plate 403 is slidably fitted inside the top cover 103. A rotating frame 405 is rotatably fitted on the lower side of the lower pressure plate 403. An ultraviolet sterilizer is installed inside the top cover 103. An air inlet pipe 601 and two lower pressure rods 501 are installed on the lower side of the rotating frame 405. The probe 701 is installed on the lower side of the rotating frame 405. The two lower pressure rods 501 are respectively installed on the sides of the air inlet pipe 601 and the probe 701. One end of the lower pressure rod 501 is in contact with the transmission structure.

[0023] Specifically, the test tube 301 is conveniently placed in the placement slot 206 by sliding the top cover 103, and then heated by the heating tube 314 to cultivate microorganisms. During the cultivation process, sliding the lower pressure plate 403 downwards will press down the air inlet pipe 601 to allow air to enter the test tube 301, ensuring the survival rate of the beef microorganisms in the test tube 301. Sliding the air inlet pipe 601 back to its original position, when the air inlet pipe 601 or the probe 701 is inserted into the auxiliary slot 207, water can be sprayed from the spray head to rinse the air inlet pipe 601 or the probe 701. When the air inlet pipe 601 and the probe 701 are reset, they are sterilized by the ultraviolet sterilizer, which can prevent cross-contamination of different microorganisms on two beef samples and improve the accuracy of the test results.

[0024] This embodiment includes: an electric slide rail 102 fixed on the base 101, the output end of the electric slide rail 102 being fixedly connected to the top cover 103, a controller 104 fixed on one side of the base 101, and a display screen 105 fixed on the controller 104; wherein, a first motor 201 is fixed inside the base 101, the output end of the first motor 201 being fixedly connected to the rotating plate 202, a water inlet pipe is fixed on one side of the base 101, and a through groove is opened on the rotating plate 202, the through groove being connected to the water inlet pipe and the spray head.

[0025] Specifically, all electrical components inside the base 101 are connected to the controller 104 via data cables, and electrical components on the top cover 103 are connected to the controller 104 via data cables and rotary conductive connectors. Therefore, intelligent control is achieved through the controller 104, and input and output are performed through the display screen 105, resulting in a better control effect. When it is necessary to place the test tube 301, the electric slide rail 102 is activated, which drives the top cover 103 to slide, thereby exposing the placement slot 206 to the outside. The test tube 301 can then be placed into the placement slot 206. When the top cover 103 is closed, the internal environment of the base 101 is isolated from the outside, thereby preventing external airborne microorganisms from affecting the microbial detection of beef and improving the accuracy of the detection.

[0026] The wiring structure includes: multiple first electrode plates 204 and multiple second electrode plates 205; the first electrode plates 204 are fixed inside the base 101, the second electrode plates 205 are fixed around the placement rack 203, the placement rack 203 has a placement cavity 208 in the middle, a male connector 209 is fixed in the placement slot 206, the male connector 209 is connected to the second electrode plate 205 through a data cable, and the first electrode plates 204 are connected to the controller 104 through a data cable; wherein, a female connector 315 is fixed at the bottom of the test tube 301, and the female connector 315 is snapped and fixed to the male connector 209.

[0027] Specifically, power is supplied through the contact between the first electrode plate 204 and the second electrode plate 205, which facilitates the heating tube 314 to be energized for heating. After the test tube 301 is placed in the placement slot 206, the male connector 209 is inserted into the female connector 315 to supply power. The snap-fit ​​relationship between the male connector 209 and the female connector 315 can also ensure the stability of the device and prevent the test tube 301 from shaking, thereby ensuring that the microorganisms in the test tube 301 can be cultured well, increasing the amount of microorganisms in the beef, and thus making it easier to detect the types of microorganisms in the beef.

[0028] A heating chamber 313 is provided on the periphery of the test tube 301. The heating chamber 313 is filled with a heating liquid. The heating tube 314 is fixed in the heating chamber 313 and is connected to the terminal 315 via a data cable.

[0029] Specifically, the heating tube 314 can heat the liquid after heating, thereby heating the inside of the test tube 301 more evenly. The temperature is controlled by the controller 104, which can ensure the constant temperature culture of beef microorganisms, thus ensuring that the microorganisms can survive and reproduce normally and ensuring the detection effect of microorganisms.

[0030] Sealing pistons 303 are fixed on both the upper and lower sides of the support frame 302. The two sealing pistons 303 and the support frame 302 are combined to form an I-shaped structure. The sealing pistons 303 are in contact with the inner wall of the test tube 301. The piston cover 304 has an opening 305. The sealing ball 306 is rotatably fitted into the opening 305. The sealing ball 306 has an insertion port 307 in the middle.

[0031] Specifically, the support frame 302 can elevate the beef, preventing the probe 701 from failing to contact the beef due to the deep space inside the test tube 301. Furthermore, the piston cap 304 and sealing ball 306 can seal the test tube 301, preventing external air containing a large number of microorganisms from contacting the beef and affecting the microbial detection of the beef, thus improving the accuracy of the test results. Additionally, inserting the probe 701 through the insertion port 307 for detection or inserting the air inlet pipe 601 for air supply can prevent the probe 701 or air inlet pipe 601 from directly contacting the sealing ball 306 and causing contamination, further improving the accuracy of the detection.

[0032] The transmission structure includes a gear 309 and a rack 310. A sliding groove 312 is provided inside the piston cover 304. The rack 310 is slidably fitted within the sliding groove 312. A first spring 316 is fixed between the rack 310 and the groove wall of the sliding groove 312. A rotating shaft 308 is fixed on the sealing ball 306. The rotating shaft 308 is perpendicular to the through-hole 305 and is rotatably connected to the piston cover 304. The gear 309 is fixed to the end of the rotating shaft 308 and meshes with the rack 310. A pressing port 311 is provided at the top of the piston cover 304 and communicates with the sliding groove 312.

[0033] Specifically, when testing or oxygen is required, the downward pressure rod 501 is slid down, causing the downward pressure port 311 of the pressure rod 501 to push through the rack 310, thereby causing the rack 310 to slide. The rack 310 drives the gear 309 to mesh and rotate, thereby driving the sealing ball 306 to rotate, so that the device is in a sealed state when not testing or air intake, thereby preventing the influence of external microorganisms and improving the accuracy of the device.

[0034] A cavity 401 is provided inside the top cover 103. The lower pressure plate 403 is slidably fitted inside the cavity 401. An electric cylinder 402 is fixed on the top cover 103. The output end of the electric cylinder 402 is fixedly connected to the lower pressure plate 403. A second motor 404 is fixed on the lower side of the lower pressure plate 403. The output end of the second motor 404 is fixedly connected to the rotating frame 405.

[0035] Specifically, activating the electric cylinder 402 causes the lower pressure plate 403 to slide downwards, which in turn causes the rotating frame 405, lower pressure rod 501, probe 701, and air inlet pipe 601 to slide downwards, thus achieving better detection and air intake effects. Activating the second motor 404 causes the rotating frame 405 to rotate, thereby adjusting the position of probe 701 and air inlet pipe 601. This allows for the detection of beef in different test tubes 301 without the test tube 301 being stationary, making the device more flexible to use and expanding its applicability.

[0036] The ultraviolet sterilizer includes: multiple first ultraviolet lamps 406 and multiple second ultraviolet lamps 407; wherein, the first ultraviolet lamps 406 are fixed on the rotating frame 405, the second ultraviolet lamps 407 are fixed on the cavity wall of the cavity 401, and the first ultraviolet lamps 406 and the second ultraviolet lamps 407 are connected to the controller 104 via data cables.

[0037] Specifically, sterilization can be achieved by emitting ultraviolet light through the first ultraviolet lamp 406 and the second ultraviolet lamp 407. The first ultraviolet lamp 406 irradiates directly downwards, which can prevent sterilization dead zones and directly sterilize the surface of the piston cover 304, thereby ensuring a sterile environment for testing and ensuring the accuracy of testing.

[0038] The lower pressure plate 403 has a first air chamber 408, and the rotating frame 405 has a second air chamber 409. The first air chamber 408 and the second air chamber 409 are connected. An air supply pipe 410 is fixed on the lower pressure plate 403. The air supply pipe 410 is slidably connected to the top cover 103 and is connected to the first air chamber 408. The lower pressure rod 501 includes a first rod body 502 and a second rod body 503. The first rod body 502 and the second rod body 503 are slidably connected. The first rod body 502 is fixedly connected to the rotating frame 405. The first rod body 502 is a hollow structure. A first electric valve 504 is installed between the first rod body 502 and the second air chamber 409. A plurality of second springs 505 are fixed between the first rod body 502 and the second rod body 503.

[0039] Specifically, when the lower pressure plate 403 slides downward, it drives the lower pressure rod 501 to slide downward simultaneously, causing the second rod 503 to insert into the lower pressure port 311 and push the rack 310 to slide until the rack 310 slides to the bottom. At this time, the second rod 503 slides upward relative to the second spring 505, which is compressed. This prevents the upper and lower sliding of the air inlet pipe 601 or the probe 701 from being limited. Furthermore, when the first electric valve 504 is opened and the second electric valve 604 is closed, the overall length of the lower pressure rod 501 can be changed by supplying or evacuating air through the air supply pipe 410. This allows for flexible control of whether the air inlet pipe 601 and the probe 701 are inserted into the test tube 301, preventing the air inlet pipe 601 and the probe 701 from being contaminated by beef. Therefore, there is no need to repeatedly clean the air inlet pipe 601 and the probe 701, improving work efficiency.

[0040] The air intake pipe 601 includes a first pipe body 602 and a second pipe body 603. The first pipe body 602 and the second pipe body 603 are slidably connected. The first pipe body 602 is fixedly connected to the rotating frame 405. A plurality of third springs 605 are fixed between the first pipe body 602 and the second pipe body 603. A second electric valve 604 is installed between the first pipe body 602 and the second air chamber 409. A protective sleeve 702 is fixed to the lower side of the rotating frame 405. A sliding plate is fixed to one end of the probe 701. The sliding plate is slidably fitted inside the protective sleeve 702. Electromagnets are fixed to both ends inside the protective sleeve 702. The electromagnets are attracted and fixed to the sliding plate.

[0041] Specifically, the second tube 603 is inserted into the test tube 301, and then connected to an oxygen or sterilized air source through the air supply tube 410. The gas is then introduced into the test tube 301, which can achieve a good gas supply effect and ensure the survival rate of microorganisms. When testing is required, the probe 701 is inserted into the beef, and detection can be performed by biochemical sensors and cell sensors. Before testing, the sliding plate can be attracted by two different electromagnets to adjust the length of the probe 701, thereby preventing the probe 701 from being inserted into the beef and causing contamination when testing is not required.

[0042] Workflow: The beef sample is placed in test tube 301. The support frame 302 elevates the beef, preventing the probe 701 from failing to contact it due to the deep space inside test tube 301. Test tube 301 is sealed by piston cap 304 and sealing ball 306. Activating electric slide rail 102 causes top cover 103 to slide, exposing placement slot 206. Test tube 301 can then be placed into placement slot 206. Power is supplied through contact between first electrode 204 and second electrode 205, facilitating heating of heating tube 314. After test tube 301 is placed in placement slot 206, male connector 209 is inserted... The female connector 315 is energized, and the snap-fit ​​connection between the male connector 209 and the female connector 315 ensures the stability of the device. Heating tube 314 heats the liquid, resulting in more uniform heating of the test tube 301. Temperature is controlled by controller 104 to ensure constant-temperature culture of beef microorganisms. When testing or oxygen introduction is required, the second motor 404 is activated, which drives the rotating frame 405 to rotate, adjusting the positions of probe 701 and air inlet pipe 601. Activating electric cylinder 402 causes the lower pressure plate 403 to slide downwards, thereby moving the rotating frame 405 and the lower pressure plate 403 downwards. The rod 501, probe 701, and air inlet pipe 601 slide downwards, causing the downward pressure port 311 of the downward pressure rod 501 to push through the rack 310, thus causing the rack 310 to slide. The rack 310 drives the gear 309 to mesh and rotate, thereby causing the sealing ball 306 to rotate. The air inlet pipe 601 or probe 701 passes through the insertion port 307 and enters the test tube 301. When the downward pressure plate 403 slides downwards, the downward pressure plate 403 drives the downward pressure rod 501 to slide downwards synchronously until the rack 310 slides to the bottom. At this time, the second rod 503 slides upwards relatively, and the second spring 505 is compressed, thereby preventing the upward and downward sliding of the air inlet pipe 601 or probe 701 from being limited. And when the first electric motor is turned on... When valve 504 is in operation, with the second electric valve 604 closed, the length of the lowering rod 501 can be changed by supplying or evacuating air through the air supply pipe 410. This allows for flexible control over whether the air inlet pipe 601 and probe 701 are inserted into the test tube 301, preventing contamination of the air inlet pipe 601 and probe 701 by beef. Therefore, repeated cleaning of the air inlet pipe 601 and probe 701 is unnecessary, improving work efficiency. The second tube 603 is inserted into the test tube 301, and then oxygen or sterilized air is connected through the air supply pipe 410 to introduce gas into the test tube 301. When testing is required, the probe 701 is inserted into the beef, and detection can be performed using biochemical and cell sensors.
