[0020] A method for using a microbial detection device for marinated beef includes the following steps:

[0021] Step 1: Open the sealing cover and add the same volume of sample solution to be detected into multiple detection chambers.

[0027] The beneficial effects of the present invention are as follows:

[0028] 1. Through the combined use of the detection mechanism and the self-cleaning mechanism of the present invention, after the detection of the sample solution is completed, the work of the self-cleaning mechanism will cause the threaded ring to move downward and the cleaning plate to rotate, so that the cleaning plate scrapes the inner surface of the detection chamber, and the cleaning frame will clean the outer surface of the probe, ensuring the cleanliness of the probe and the detection chamber, thus guaranteeing the accuracy of the probe for the subsequent detection of the sample solution.

[0029] 2. By providing the filter frame, when detecting the sample solution, since the filter frame is at the top, it can filter the sample solution that submerges the probe, removing the impurities contained in the sample solution, preventing the impurities from adhering to the outer surface of the probe and affecting the detection accuracy, improving the detection accuracy, and avoiding foreign objects in the environment from falling into the detection chamber during detection or when not in use, affecting the cleanliness of the probe, thus ensuring the accuracy of the probe's detection of the sample solution.

[0030] 3. Through the combined use of the driving mechanism, the detection mechanism, and the self-cleaning mechanism, when it is necessary to clean after detecting the sample solution, the driving mechanism is started, which in turn causes the self-cleaning mechanism to rotate. The threaded ring in the self-cleaning mechanism will move downward along the outer surface of the threaded rod under the limiting action of the cleaning frame and the probe, causing the cleaning frame to move downward along the outer surface of the probe. And the cleaning plate in the self-cleaning mechanism will rotate along the inner surface of the detection chamber. At the same time, the water pump is started to inject pure water into the detection chamber through the water injection hole. Meanwhile, due to the rotation of the cleaning plate, the cleaning plate will stir the pure water, improving the fluidity of the pure water, enabling the pure water to better clean the probe and the detection chamber, and improving the cleaning efficiency and quality of the probe and the detection chamber.

[0041] The present application will be further described in detail below with reference to the accompanying drawings. It is necessary to point out here that the following detailed implementation manners are only used to further illustrate the present application and cannot be understood as limiting the protection scope of the present application. Those skilled in the art can make some non-essential improvements and adjustments to the present application according to the above application content.

[0042] Example: As Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 and Figure 7As shown in the figure, a microbial detection device for marinated beef includes a microbial detector 1, a controller 2, a printer 3, a detection area 4, and a sealing cover 5. It also includes: a groove opened on the microbial detector 1 and located within the detection area 4; the controller 2 is installed on the top of the microbial detector 1, and the controller 2 is electrically connected to the microbial detector 1; the printer 3 is installed on the top of the microbial detector 1, and the printer 3 is electrically connected to the controller 2; the detection area 4 is arranged on the top of the microbial detector 1; the sealing cover 5 is installed within the detection area 4, and a grip is installed on the sealing cover 5 to facilitate the opening and closing of the sealing cover 5; a dirt storage chamber 10 is opened within the microbial detector 1, and a discharge pipe 11 communicating with the interior of the dirt storage chamber 10 is installed on the back of the microbial detector 1. The discharge pipe 11 is fixedly connected to a waste liquid collection tank (the waste liquid collection tank is a prior art and is not shown in the figure and will not be elaborated in detail). A valve is installed within the discharge pipe 11, and the valve is controlled by the controller 2. A liquid storage mechanism 6 is arranged within the groove. The liquid storage mechanism 6 is used for storing the sample solution to be detected and pure water. The liquid storage mechanism 6 includes a fixed disk 601 fixedly connected within the groove. A pure water chamber 602 is opened within the fixed disk 601. A cover plate 603 is installed on the top of the pure water chamber 602. A water filling hole is opened on the cover plate 603, and a sealing plug is installed within the water filling hole. A detection chamber 604 is opened on the fixed disk 601. The top of the detection chamber 604 is square to facilitate the insertion of a drainage tube, thereby preventing the sample solution from entering other detection chambers 604 when injecting the sample solution into the detection chamber 604, which affects the detection accuracy. A filter frame 606 is installed within the square part of the detection chamber 604. A sewage discharge pipe 605 fixedly connected to the detection chamber 604 is fixedly connected to the bottom of the fixed disk 601. A valve is installed within the sewage discharge pipe 605, and the valve is controlled by the controller 2. The sewage discharge pipe 605 is fixedly connected to the dirt storage chamber 10.

[0043] During use, close the sewage discharge pipe 605, hold the grip and open the sealing cover 5, insert the drainage tube into the detection chamber 604, and then pour the sample solution to be detected into multiple detection chambers 604. Since the filter frame 606 is at the top, at this time, through the filter frame 606, the sample solution submerging the probe 703 can be filtered to remove the impurities contained in the sample solution, preventing the impurities from adhering to the outer surface of the probe 703 and affecting the detection accuracy, improving the detection accuracy. And during detection or when not in use, it can prevent foreign objects in the environment from falling into the detection chamber 604 and affecting the cleanliness of the probe 703, thus ensuring the accuracy of the probe 703 in detecting the sample solution. Then pull out the drainage tube and close the sealing cover 5. At this time, the controller 2 can be controlled to start the detection. The detection results obtained are printed by the printer 3. At this time, the sewage discharge pipe 605 and the discharge pipe 11 can be opened to discharge the waste liquid.

[0044] Such as Figure 3 、 Figure 5 、 Figure 7 、 Figure 8 andFigure 9 As shown, the microorganism detection device further includes a detection mechanism 7 installed in the liquid storage mechanism 6. The detection mechanism 7 includes a probe 703 for detecting a sample solution to be detected. The detection mechanism 7 further includes a data line 701 fixedly connected in the groove. The end of the data line 701 is fixedly connected with a probe head 702. The probe head 702 is electrically connected to the probe 703. The probe head 702 is electrically connected to the data line 701. The data line 701 is connected to the microorganism detector 1. The probe head 702 is fixedly connected to the probe 703. The probe head 702 is fixedly connected to the bottom of the fixed disk 601. The probe 703 penetrates through the detection chamber 604 and extends into the detection chamber 604.

[0045] During detection, the probe 703 is activated to detect microorganisms in the sample solution. The probe 703 sends the detected data to the microorganism detector 1. The microorganism detector 1 sends the data to the controller 2. At this time, the controller 2 will determine and record the detection result of the sample solution. Then, the detection result of the sample solution is compared with the standard curve to determine the composition of microorganisms in the sample solution.

[0046] As Figure 3 、 Figure 5 、 Figure 7 、 Figure 8 and Figure 9As shown, the microbial detection device further includes a self-cleaning mechanism 9 installed in the liquid storage mechanism 6. The self-cleaning mechanism 9 includes a cleaning frame 907 attached to the outer surface of the probe 703. A threaded ring 906 is fixedly connected to the top of the cleaning frame 907. A threaded rod 909 is threadedly connected to the outer surface of the threaded ring 906. A cleaning plate 908 is fixedly connected to the top end of the threaded rod 909. The length of the cleaning plate 908 is the same as the length of the detection chamber 604 after removing the square part. The self-cleaning mechanism 9 further includes a water pump 903 fixedly connected to the bottom of the pure water chamber 602. A water injection pipe 902 is fixedly connected to the drainage end of the water pump 903. A fixed rod 901 is fixedly connected to the inner bottom of the groove. The top end of the fixed rod 901 is sealingly and rotatably connected to the bottom end of the threaded rod 909. The water injection pipe 902 is fixedly connected to the fixed rod 901. A water delivery groove 904 is formed in the threaded rod 909. The water delivery groove 904 is internally connected to the water injection pipe 902. The threaded rod 909 passes through the detection chamber 604 and is sealingly and rotatably connected to the detection chamber 604. A water injection hole 905 is formed in the inner bottom of the detection chamber 604 where the threaded rod 909 is located. The water injection hole 905 is internally connected to the water delivery groove 904. A one-way valve is installed at the inner top end of the water delivery groove 904 to prevent the sample solution from entering the water delivery groove 904 when detecting the sample solution. It further includes a driving mechanism 8 installed in the liquid storage mechanism 6 for driving the self-cleaning mechanism 9. The driving mechanism 8 includes a servo motor 801 fixedly connected to the groove. The output end of the servo motor 801 is fixedly connected to a rotating shaft 802. The rotating shaft 802 is rotatably connected to the bottom of the fixed disk 601. A first gear 803 is fixedly connected to the outer surface of the rotating shaft 802. A second gear 804 is meshed with the outer surface of the first gear 803. The second gear 804 is fixedly connected to the threaded rod 909.

[0047] After the sample solution to be detected is poured into the detection chamber 604 and before the detection starts, the servo motor 801 can be started. The operation of the servo motor 801 will drive the second gear 804 to rotate through the rotating shaft 802 and the first gear 803. The rotation of the second gear 804 will drive the threaded rod 909 to rotate, and then drive the cleaning plate 908 to rotate, stirring the sample solution to be detected entering the detection chamber 604, further ensuring the uniformity of the sample, and thus improving the detection accuracy.

[0048] After the detection is completed, when the sample solution to be detected needs to be cleaned after being completely discharged through the sewage discharge pipe 605, close the valve in the sewage discharge pipe 605, remove the filter frame 606 and clean the filter frame 606. Start the water pump 903 so that the water pump 903 pumps the pure water in the pure water chamber 602 into the water injection pipe 902, then into the water trough 904, and finally injects it into the detection chamber 604 through the water injection hole 905 until the pure water fills the detection chamber 604. At this time, the operation of the servo motor 801 will drive the second gear 804 to rotate through the rotating shaft 802 and the first gear 803. The rotation of the second gear 804 will drive the threaded rod 909 to rotate. At this time, since the probe 703 is fixed, the rotation of the threaded rod 909 will cause the threaded ring 906 to move downward along the outer surface of the threaded rod 909 under the limiting action of the cleaning frame 907 and the probe 703, thereby causing the cleaning frame 907 to move up and down along the outer surface of the probe 703 to clean the outer surface of the probe 703. At the same time, since the cleaning plate 908 is attached to the inner surface of the detection chamber 604, the cleaning plate 908 will clean the inner surface of the detection chamber 604. The pure water entering the detection chamber 604 will flow under the rotation of the cleaning plate 908, prompting the pure water to impact the detection chamber 604 and the probe 703, removing the impurities generated during the detection on the detection chamber 604 and the probe 703, enabling the pure water to better clean the detection chamber 604 and the probe 703, improving the cleaning efficiency and cleaning quality of the detection chamber 604 and the probe 703, and facilitating subsequent detection operations.

[0049] As Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 、 Figure 5 、 Figure 6 、 Figure 7 、 Figure 8 and Figure 9 shown, a method for using a microbial detection device for marinated beef includes the following steps:

[0050] Step 1: Open the sealing cover 5 and add the same volume of sample solution to be detected into multiple detection chambers 604;

[0051] Close the sewage discharge pipe 605, hold the handle and open the sealing cover 5, insert the drainage pipe into the detection chamber 604, and then pour the sample to be detected into multiple detection chambers 604. Since the filter frame 606 is at the top, at this time, through the filter frame 606, the sample solution submerging the probe 703 can be filtered to remove the impurities contained in the sample solution, avoiding the impurities adhering to the outer surface of the probe 703 and affecting the detection accuracy, improving the detection accuracy, and being able to prevent foreign objects in the environment from falling into the detection chamber 604 during detection or when not in use, affecting the cleanliness of the probe 703, thereby ensuring the accuracy of the probe 703 for detecting the sample solution;

[0052] Step 2: Close the sealing cover 5, and start the probe 703 in the detection chamber 604 with the sample solution to be detected to detect the microorganisms in the braised beef;

[0053] Then pull out the drainage tube and close the sealing cover 5. At this time, the controller 2 can be controlled to start the probe 703 to detect the microorganisms in the sample solution. The probe 703 sends the detected data to the microorganism detector 1, and the microorganism detector 1 sends the data to the controller 2. At this time, the controller 2 will determine and record the detection result of the sample solution. At this time, the detection result of the sample solution is compared with the standard curve to determine the composition of the microorganisms in the sample solution;

[0054] Step 3: During the detection process, the controller 2 records the detection result of the sample solution;

[0055] Step 4: Compare the detection result of the sample solution with the standard curve to determine the composition of the microorganisms in the braised beef;

[0056] Step 5: After obtaining the detection result, open the sewage pipe 605 to discharge the detected sample solution, and start the driving mechanism 8 corresponding to the detection chamber 604 with the sample solution to be detected;

[0057] Open the sewage pipe 605 and the discharge pipe 11 to discharge the waste liquid;

[0058] Step 6: Make the self-cleaning mechanism 9 clean the probe 703 and the detection chamber 604. The waste liquid generated by the cleaning is discharged into the sewage storage chamber 10 through the sewage pipe 605, and then open the discharge pipe 11 to discharge the waste liquid;

[0059] After the detection is completed, when the sample solution to be detected needs to be cleaned after being completely discharged through the sewage discharge pipe 605, close the valve in the sewage discharge pipe 605, remove the filter frame 606 and clean the filter frame 606. Start the water pump 903 so that the water pump 903 pumps the pure water in the pure water chamber 602 into the water injection pipe 902, then into the water delivery tank 904, and finally injects it into the detection chamber 604 through the water injection hole 905 until the pure water fills the detection chamber 604. At this time, the operation of the servo motor 801 will drive the second gear 804 to rotate through the rotating shaft 802 and the first gear 803. The rotation of the second gear 804 will drive the threaded rod 909 to rotate. At this time, since the probe 703 is fixed, the rotation of the threaded rod 909 will cause the threaded ring 906 to move downward along the outer surface of the threaded rod 909 under the limiting action of the cleaning frame 907 and the probe 703, and then cause the cleaning frame 907 to move up and down along the outer surface of the probe 703 to clean the outer surface of the probe 703. At the same time, since the cleaning plate 908 is in contact with the inner surface of the detection chamber 604, the cleaning plate 908 will clean the inner surface of the detection chamber 604. The pure water entering the detection chamber 604 will flow under the rotation of the cleaning plate 908, prompting the pure water to impact the detection chamber 604 and the probe 703, removing the impurities generated during the detection on the detection chamber 604 and the probe 703, enabling the pure water to better clean the detection chamber 604 and the probe 703, improving the cleaning efficiency and cleaning quality of the detection chamber 604 and the probe 703, and facilitating subsequent detection operations;

[0060] After cleaning, open the valves in the sewage discharge pipe 605 and the discharge pipe 11. Therefore, the sewage generated during cleaning will be discharged into the sewage storage chamber 10 through the sewage discharge pipe 605, and then discharged into the waste liquid collection box through the discharge pipe 11.

[0061] The above embodiments only represent several implementation manners of the present invention. The description is relatively specific and detailed, but it should not be construed as a limitation on the scope of the patent of the present invention. It should be noted that for those of ordinary skill in the art, without departing from the concept of the present invention, several deformations and improvements can still be made, and these all belong to the protection scope of the present invention.
