Description

Technical Field

[0001] This invention relates to the field of microbial stirring detection technology, specifically to a stirring-type hot pot base microbial detection device. Background Technology

[0002] Hot pot base is a common ingredient, known for its flavor-enhancing properties. During its production, microbial testing is crucial to ensure safety. This necessitates the use of microbial testing equipment. Fluorescence detection can be employed, requiring the addition of specific fluorescent dyes or markers to the sample followed by stirring. Insufficient stirring can negatively impact test results. To address this, prior art 1 (Chinese patent application No. 202410359016.5, filed March 27, 2024) describes a rapid microbial detection device for food testing. This device incorporates a rotating rod and a stirring chamber, enabling rapid sample mixing for subsequent processing. For subsequent testing, prior art 2 (Chinese patent application No. 202220452475.4, filed on 2022-03-04) describes a food microbiology testing device. During operation, it solves the problems of existing food microbiology testing devices being unable to mix microorganisms, making it inconvenient to sample multiple microbial samples for testing, inconvenient for operators to conduct comparative observations of multiple microbial samples, and difficult to control experimental temperature, which is detrimental to microbial testing experiments. Prior art 3 (Chinese patent application No. 202120532540.X, filed on 2021-03-15) describes a food microbiology testing device that incorporates a pulverizing structure and a stirring structure during operation, allowing for good mixing of samples during subsequent testing.

[0003] In actual testing, a single mixing structure is still insufficient to meet the mixing depth requirements of microbial samples and auxiliary reagents. Furthermore, the detection device in the aforementioned application lacks an auxiliary mixing structure, which can still cause deviations in the test results and bring unnecessary trouble to the testing process. Summary of the Invention

[0004] The purpose of this invention is to provide a stirring-type hot pot base microbial detection device to solve the problem mentioned in the background art that, during use, the lack of an auxiliary mixing structure still causes deviations in the detection results and brings unnecessary trouble to the detection process.

[0006] Preferably, the working rod is sleeved and connected to the surface of the connecting shaft, and a circular plate is fixedly connected to the surface of the working rod, and a second magnet is fixedly connected to the upper surface of the circular plate.

[0007] Preferably, the lifting mechanism includes a first magnet fixedly connected to the inner wall of the cover plate, and the magnetic poles on the lower surface of the first magnet are opposite to the magnetic poles on the upper surface of the second magnet, and the second magnets are evenly distributed on the upper surface of the circular plate.

[0008] Preferably, a limiting block is fixedly connected to the outer wall of the connecting shaft, and the limiting blocks are symmetrically distributed on both sides of the connecting shaft. The working rod has a limiting groove inside that corresponds to the limiting block.

[0009] Preferably, the scrapers are symmetrically distributed on both sides of the cover plate, and the surface of the scrapers is arc-shaped. The surface of the scrapers is in contact with the inner wall of the detection box, and the surface of the scrapers is provided with through holes at equal angles. The stirring blades are distributed at equal intervals on the surface of the working rod.

[0010] Preferably, the reciprocating mechanism includes an upper connecting block fixedly connected to the upper surface of the long pin, and the surface of the upper connecting block is provided with a guide groove, and a crossbar is fixedly connected to the surface of the connecting shaft.

[0011] Preferably, the crossbar corresponds one-to-one with the guide groove, and the end of the crossbar is located inside the guide groove. The auxiliary plate is fixedly connected to the long pin, and the auxiliary plate is evenly distributed on the surface of the long pin. The upper surface of the auxiliary plate has an arc-shaped structure, and the upper surface of the auxiliary plate is fixedly connected with a lever at equal angles.

[0012] Preferably, the moving mechanism includes a limiting rod fixedly connected to the inner wall of the outer plate on one side, and a sliding rod is sleeved on the surface of the limiting rod, and the push rod is fixedly connected to the lower surface of the limiting rod, with a ball rotatably disposed at the end of the push rod.

[0013] Preferably, a push block is fixedly connected to the surface of the long pin, and the surface of the push block is raised. A connecting spring that plays an elastic restoring role is fixedly connected to the surface of the slide rod, and the other side of the connecting spring is fixedly connected to the inner wall of the outer plate.

[0014] Preferably, an auxiliary ball is rotatably connected to the other end of the push rod, the surface of the push block is in contact with the surface of the auxiliary ball, and the part of the working rod located below the outer plate is a rubber flexible rod.

[0015] Compared with the prior art, the beneficial effects of this invention are as follows: The novel structural design, with its reciprocating working rod and stirring blades in the vertical direction, optimizes the mixing effect. Furthermore, during operation, the long pin, auxiliary plate, and lever are in a reciprocating rotational state, providing lateral auxiliary mixing. The lower end of the working rod is a flexible rubber rod, which oscillates during rotation, also aiding in mixing. This ensures that the material inside the detection box is deeply mixed, improving the accuracy of the detection results. The specific details are as follows:

[0016] This stirring-type hot pot base microbial detection equipment is used by pouring microbial samples and fluorescent reagents into the detection box, then closing the cover and starting the motor. When the motor is working, it drives the connecting shaft and the working rod to rotate. At this time, the stirring blade plays a mixing role. During this process, the working rod and the stirring blade also make reciprocating linear motion in the vertical direction. At this time, the stirring blade has a better mixing effect, which can make the sample and reagent mix better and make the test results more accurate.

[0017] This stirring-type hot pot base microbial testing equipment, when the working rod rotates, will drive the circular plate to rotate synchronously. At this time, the second magnet will intermittently approach the first magnet. Then, under the action of mutual magnetic attraction and their own gravity, the circular plate and the working rod slide on the surface of the connecting shaft. At this time, the stirring blade is not only rotating, but also moving up and down, which optimizes the mixing effect, facilitates the subsequent testing work of the staff, and improves the accuracy.

[0018] In this stirring-type hot pot base microbial testing equipment, when the working rod drives the outer plate to rise, the long pin and the upper connecting block rise synchronously. At this time, the crossbar will drive the upper connecting block and the long pin to rotate through the guide groove. When the working rod drives the outer plate to fall, the crossbar will drive the upper connecting block and the long pin to rotate through the guide groove. The above process is repeated. The upper connecting block, the long pin and the auxiliary plate are in a reciprocating rotation state. At this time, the auxiliary plate and the pusher also play a role in assisting mixing.

[0019] Furthermore, the auxiliary plate and the lever are in a reciprocating rotation state, which has a better mixing effect than rotating in the same direction continuously.

[0020] This stirring-type hot pot base microbial detection equipment, when the long pin reciprocates, drives the push block to rotate synchronously. At this time, the protrusions on the surface of the push block will intermittently push the auxiliary ball and the push rod. Then, the push rod, the auxiliary ball, and the slide rod will make reciprocating linear motion in the horizontal direction under the action of the thrust, the limit rod, and the connecting spring. At this time, the push rod will intermittently push the working rod, causing the lower end of the working rod (the rubber soft rod position) to swing, which in turn causes the stirring blade to swing. At this time, the stirring blade has a better mixing effect, allowing the microbial sample and the fluorescent reagent to mix better. Therefore, when the laser emitter and the fluorescence detector are used for detection, the results are more accurate.

[0021] Furthermore, when the working rod moves, it drives the scraper to move synchronously. At this time, the scraper can effectively clean the inner wall of the test box, preventing material residue from remaining on the inner wall of the test box, which facilitates subsequent cleaning by the staff.

[0035] 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.

[0036] This invention provides the following technical solution: a stirring-type hot pot base microbial detection device.

[0037] Example 1: By using the motor 3 and stirring blade 6, the sample and reagents inside the detection cartridge 1 can be efficiently mixed during reagent mixing, such as... Figures 1-7 As shown, the device includes a detection box 1 and a cover plate 2. The upper surface of the detection box 1 is provided with the cover plate 2, and the upper surface of the cover plate 2 is bolted to a motor 3, and the output end of the motor 3 is fixedly connected to a connecting shaft 4. A laser emitter 7 is fixedly connected to the inner wall of the cover plate 2, and a fluorescence detector 8 is fixedly connected to the inner wall of the cover plate 2. The lower surface of the cover plate 2 is connected to a working rod 5 through a lifting mechanism, and an outer plate 12 is fixedly connected to the surface of the working rod 5, and a stirring blade 6 is fixedly connected to the surface of the working rod 5. The working rod 5 is sleeved and connected to the surface of the connecting shaft 4, and a circular plate 13 is fixedly connected to the surface of the working rod 5, and a second magnet 14 is fixedly connected to the upper surface of the circular plate 13.

[0038] The lifting mechanism includes a first magnet 11 fixedly connected to the inner wall of the cover plate 2, and the magnetic poles on the lower surface of the first magnet 11 are opposite to the magnetic poles on the upper surface of the second magnet 14. The second magnet 14 is distributed at equal angles on the upper surface of the circular plate 13. Limiting blocks 9 are fixedly connected to the outer wall of the connecting shaft 4, and the limiting blocks 9 are symmetrically distributed on both sides of the connecting shaft 4. The working rod 5 has a limiting groove 10 that corresponds one-to-one with the limiting block 9 inside.

[0039] Scrapers 15 are symmetrically distributed on both sides of the cover plate 2, and the surface of scraper 15 is arc-shaped. The surface of scraper 15 is in contact with the inner wall of the detection box 1, and through holes are opened at equal angles on the surface of scraper 15. Stirring blades 6 are evenly distributed on the surface of working rod 5. Long pins 16 are rotatably connected inside the outer plate 12, and long pins 16 are connected to auxiliary plate 17 through reciprocating mechanism.

[0040] During use, the microbial sample and fluorescent reagent are poured into the detection box 1, then the cover plate 2 is closed, and the motor 3 is started. When the motor 3 is working, it drives the connecting shaft 4 and the working rod 5 to rotate. At this time, the stirring blade 6 plays a mixing role. When the working rod 5 rotates, it drives the circular plate 13 to rotate synchronously. At this time, the second magnet 14 will intermittently approach the first magnet 11. When the second magnet 14 approaches the first magnet 11, the circular plate 13, the working rod 5 and the outer plate 12 rise under the mutual magnetic attraction. When the second magnet 14 moves away from the first magnet 11, the circular plate 13, the working rod 5 and the outer plate 12 fall under their own gravity. That is, the circular plate 13, the working rod 5 and the scraper 15 slide up and down on the surface of the connecting shaft 4 (the limiting block 9 and the limiting groove 10 limit the movement distance and direction of the working rod 5 to ensure stability). At this time, the stirring blade 6 is not only rotating, but also moving up and down, which optimizes the mixing effect and makes the results more accurate when the staff conducts the test.

[0041] Example 2: Unlike Example 1, the upper connecting block 19 and guide groove 21 allow the long pin 16, auxiliary plate 17, and toggle block 18 to reciprocate, optimizing the mixing effect. Figure 8 As shown, the reciprocating mechanism includes an upper connecting block 19 fixedly connected to the upper surface of the long pin 16, and a guide groove 21 is provided on the surface of the upper connecting block 19. A crossbar 20 is fixedly connected to the surface of the connecting shaft 4. The crossbar 20 corresponds one-to-one with the guide groove 21, and the end of the crossbar 20 is located inside the guide groove 21. The auxiliary plate 17 is fixedly connected to the long pin 16, and the auxiliary plate 17 is evenly distributed on the surface of the long pin 16. The upper surface of the auxiliary plate 17 has an arc-shaped structure, and a lever 18 is fixedly connected to the upper surface of the auxiliary plate 17 at equal angles.

[0042] When the working rod 5 drives the outer plate 12 to rise, the long pin 16 and the upper connecting block 19 rise synchronously. At this time, the crossbar 20 will drive the upper connecting block 19 and the long pin 16 to rotate through the guide groove 21. When the working rod 5 drives the outer plate 12 to fall, the crossbar 20 will drive the upper connecting block 19 and the long pin 16 to rotate through the guide groove 21. The above process is repeated. The upper connecting block 19, the long pin 16 and the auxiliary plate 17 are in a reciprocating rotation state. At this time, the auxiliary plate 17 and the lever 18 also play a role in assisting mixing. The auxiliary plate 17 and the lever 18 are in a reciprocating rotation state. Compared with rotating in the same direction all the time, the reciprocating rotation of the auxiliary plate 17 and the lever 18 has a better mixing effect, so that the test sample and the fluorescent reagent are fully mixed and the test results are not deviated.

[0043] Example 3: Unlike Example 2, the push rod 24 allows the working rod 5 and the stirring blade 6 to oscillate, thus optimizing the mixing effect. Figures 9-12 As shown, the interior of the outer plate 12 is connected to a push rod 24 via a moving mechanism, and the end of the push rod 24 is in contact with the surface of the working rod 5. The moving mechanism includes a limiting rod 23 fixedly connected to the inner wall of one side of the outer plate 12, and a sliding rod 26 is sleeved on the surface of the limiting rod 23. The lower surface of the limiting rod 23 is fixedly connected to the push rod 24, and a ball bearing 28 is rotatably provided at the end of the push rod 24.

[0044] A push block 22 is fixedly connected to the surface of the long pin 16, and the surface of the push block 22 is raised. A connecting spring 27 that plays an elastic restoring role is fixedly connected to the surface of the slide rod 26, and the other side of the connecting spring 27 is fixedly connected to the inner wall of the outer plate 12. An auxiliary ball 25 is rotatably connected to the end of the other side of the push rod 24. The surface of the push block 22 is in contact with the surface of the auxiliary ball 25. The part of the working rod 5 located below the outer plate 12 is a rubber flexible rod. A scraper 15 is fixedly connected to the surface of the outer plate 12.

[0045] When the long pin 16 reciprocates, it drives the push block 22 to rotate synchronously. At this time, the protrusions on the surface of the push block 22 will intermittently push the auxiliary ball 25 and the push rod 24. When the auxiliary ball 25 and the push rod 24 are pushed by the push block 22, the push rod 24 drives the slide rod 26 to slide on the surface of the limit rod 23. At this time, the connecting spring 27 is compressed. When the auxiliary ball 25 and the push rod 24 are not pushed, the auxiliary ball 25, the push rod 24, and the slide rod 26 return to their original positions under the action of the connecting spring 27, and the above process is repeated. At this time, the push rod 25... 4. The push rod 24 intermittently pushes the working rod 5, causing the lower end of the working rod 5 (the rubber flexible rod position) to swing, which in turn causes the stirring blade 6 to swing. At this time, the stirring blade 6 has a better mixing effect, allowing the microbial sample and fluorescent reagent to mix better. After deep mixing, the microbial detection work can be completed by the laser emitter 7 and the fluorescence detector 8. The rolling ball 28 plays a limiting role during operation, allowing the end of the push rod 24 to better connect with the working rod 5.

[0046] During the rotation of the working rod 5 and the stirring blade 6, the working rod 5 drives the outer plate 12 and the scraper 15 to rotate synchronously. At this time, the scraper 15 plays the role of cleaning the inner wall of the detection box 1, so that no material remains on the inner wall of the detection box 1.

[0047] The above is the entire working process of the device, and all contents not described in detail in this specification are existing technologies known to those skilled in the art.

[0048] Although the present invention 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. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
