Description

Technical Field

[0001] The present invention relates to the technical field of microbial stirring detection, and in particular to a microbial detection device for stirred hot pot base materials. Background Art

[0002] Hot pot base materials are a common ingredient with the function of enhancing fragrance and flavor. During the production of hot pot base materials, it is necessary to detect microorganisms to ensure the safety of production. At this time, a microbial detection device for hot pot base materials is required. When detecting microorganisms, the fluorescence detection method can be used. During fluorescence detection, a specific fluorescent dye or marker needs to be added to the microorganism sample and then stirred. If the stirring depth is insufficient, it will affect the detection result. To achieve deep stirring, in the prior art 1 (a Chinese patent application with the application number 202410359016.5 and the application date of March 27, 2024), a rapid food microorganism detection device for food detection is provided. When it works, a rotating rod and a stirring box are set to quickly mix the sample, facilitating subsequent detection work. In the prior art 2 (a Chinese patent application with the application number 202220452475.4 and the application date of March 4, 2022), a food microorganism detection device is provided. When it works, it solves the problems that the existing food microorganism detection device cannot stir and mix microorganisms, is not convenient for sampling multiple microorganism samples for detection, is not convenient for the operator to conduct experimental comparison and observation on multiple microorganism samples, and is not convenient for controlling the experimental temperature, which is not conducive to the microorganism detection experiment. In the prior art 3 (a Chinese patent application with the application number 202120532540.X and the application date of March 15, 2021), a food microorganism detection device is provided. When it works, a crushing structure and a stirring structure are set to enable the sample to be well mixed during subsequent detection.

[0003] However, in the actual detection process, a single mixing structure is still difficult to meet the mixing depth requirements of microorganism samples and auxiliary reagents. During the use of the detection devices in the above applications, there is no auxiliary mixing structure, which will still cause deviations in the detection results and bring unnecessary troubles to the detection process. Summary of the Invention

[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 distributed at equal angles 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, and limiting grooves corresponding to the limiting blocks are opened inside the working rod.

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

[0010] Preferably, the reciprocating mechanism comprises an upper connecting block fixedly connected to the upper surface of the long pin, and a guide groove is provided on the surface of the upper connecting block, and a cross bar is fixedly connected to the surface of the connecting shaft.

[0011] Preferably, the cross bar corresponds to the guide groove one by one, and the end of the cross bar is located inside the guide groove, the auxiliary plate is fixedly connected to the long pin, and the auxiliary plates are evenly spaced on the surface of the long pin, and the upper surface of the auxiliary plate is an arc structure, and the upper surface of the auxiliary plate is fixedly connected with a shift block at equal angles.

[0012] Preferably, the moving mechanism includes a limiting rod fixedly connected to the inner wall of the external connecting plate on one side, and the surface of the limiting rod is sleeved with a sliding rod, and the lower surface of the limiting rod is fixedly connected to the push rod, and a rolling ball is rotatably arranged 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 convex, and a connecting spring that plays an elastic reset 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 external plate.

[0014] Preferably, the end of the other side of the push rod is rotatably connected to an auxiliary ball, the surface of the push block fits with the surface of the auxiliary ball, and the portion of the working rod located below the external plate is a rubber soft rod.

[0015] Compared with the prior art, the beneficial effects of the present invention are: adopting a new structural design, by setting a working rod and a stirring blade that can reciprocate in the vertical direction, the mixing effect is optimized, and in addition, when working, the long pin, the auxiliary plate and the dial block are in a reciprocating rotation state, which plays a role of side auxiliary mixing, and the lower end of the working rod is a rubber soft rod. When rotating, the lower end of the working rod is in a swinging state, which also plays a role of auxiliary mixing, so that the material inside the detection box can be deeply mixed, and the accuracy of the detection result is improved. The specific contents are as follows: During use of the stirring hot pot base microbial detection equipment, the microbial sample and the fluorescent reagent are poured into the detection box, and then the cover is closed and the motor is started. 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. In 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 the reagent mix better and make the detection result more accurate.

[0016] When the working rod of the stirring hot pot base microbial detection equipment rotates, the circular plate will be driven to rotate synchronously. At this time, the second magnet will intermittently approach the first magnet, and then the circular plate and the working rod will slide on the surface of the connecting shaft under the action of mutual magnetic force and their own gravity. At this time, the stirring blade is not only in a rotating state, but also in a state of moving up and down, which optimizes the mixing effect, facilitates the subsequent detection work of the staff, and improves the accuracy.

[0017] In the stirring type hot pot base microbial detection equipment, when the working rod drives the external plate to rise, the long pin and the upper connecting block rise synchronously. At this time, the cross bar will drive the upper connecting block and the long pin to rotate through the guide groove. When the working rod drives the external plate to descend, the cross bar will drive the upper connecting block and the long pin to rotate through the guide groove. The above process is repeated, and 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 shifting block also play a role in auxiliary mixing.

[0018] Furthermore, the auxiliary plate and the shifting block are in a reciprocating rotation state, and compared with rotating in the same direction all the time, the reciprocating rotation has a better mixing effect.

[0019] For this microbial detection device of the stirred hot pot base material, when the long pin rotates reciprocally, the long pin will drive the push block to rotate synchronously. At this time, the protruding position on the surface of the push block will intermittently push the auxiliary ball and the push rod. Then, under the action of the thrust force, the limiting rod and the connecting spring, the push rod, the auxiliary ball and the sliding rod will perform reciprocating linear motion in the horizontal direction. At this time, the push rod will intermittently push the working rod, causing the lower end (the position of the rubber soft rod) of the working rod to swing. Thus, the stirring blade can be made to swing. At this time, the stirring blade has a better material mixing effect, enabling better mixing of the microbial sample and the fluorescent reagent. Therefore, when the laser emitter and the fluorescence detector perform the detection work, the results are more accurate.

[0020] Furthermore, when the working rod moves, it drives the scraper to move synchronously. At this time, the scraper can well clean the inner wall of the detection box, preventing materials from remaining on the inner wall of the detection box, which is convenient for subsequent cleaning by the staff.

Specific implementation manner

[0023] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0024] The present invention provides the following technical solution: a stirring type hot pot bottom material microorganism detection device.

[0025] Embodiment 1: By setting the motor 3 and the stirring blade 6, when mixing the reagent, the samples and reagents inside the detection box 1 can be efficiently mixed. As Figures 1-7 shown, it includes a detection box 1 and a cover plate 2. The cover plate 2 is arranged on the upper surface of the detection box 1, and the motor 3 is bolted to the upper surface of the cover plate 2, and the output end of the motor 3 is fixedly connected with 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 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.

[0026] The lifting mechanism includes a first magnet 11 fixedly connected to the inner wall of the cover plate 2. The magnetic pole on the lower surface of the first magnet 11 is opposite to the magnetic pole on the upper surface of the second magnet 14, and the second magnets 14 are evenly distributed 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. Limiting grooves 10 corresponding to the limiting blocks 9 one by one are opened inside the working rod 5.

[0027] The scraping plates 15 are symmetrically distributed on both sides of the cover plate 2, and the surface of the scraping plates 15 is an arc-shaped structure. Moreover, the surface of the scraping plates 15 is in contact with the inner wall of the detection box 1, and through holes are provided at equal angles on the surface of the scraping plates 15. The stirring blades 6 are evenly distributed on the surface of the working rod 5. A long pin 16 is rotatably connected inside the external connection plate 12, and the long pin 16 is connected to an auxiliary plate 17 through a reciprocating mechanism.

[0028] During use, pour the microbial sample and the fluorescent reagent into the detection box 1, then cover the cover plate 2, and start the motor 3. When the motor 3 works, it drives the connecting shaft 4 and the working rod 5 to rotate. At this time, the stirring blades 6 play a role in mixing. 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 external connection plate 12 rise under the action of the mutual attraction magnetic force. When the second magnet 14 moves away from the first magnet 11, the circular plate 13, the working rod 5, and the external connection plate 12 descend under the action of their own gravity, that is, the circular plate 13, the working rod 5, and the scraping plates 15 slide up and down on the surface of the connecting shaft 4 (the limiting block 9 and the limiting groove 10 limit the moving distance and direction of the working rod 5, ensuring stability). At this time, the stirring blades 6 are not only in a rotating state but also in an up-and-down moving state, optimizing the mixing effect and making the results more accurate when the staff conducts the detection.

[0029] Embodiment 2: Different from Embodiment 1, by providing the upper connection block 19 and the guiding groove 21, the long pin 16, the auxiliary plate 17, and the dial block 18 can be in a reciprocating rotation state, optimizing the mixing effect. As Figure 8 shown, the reciprocating mechanism includes an upper connection block 19 fixedly connected to the upper surface of the long pin 16. A guiding groove 21 is provided on the surface of the upper connection block 19. A cross bar 20 is fixedly connected to the surface of the connecting shaft 4. The cross bars 20 correspond to the guiding grooves 21 one by one, and the ends of the cross bars 20 are located inside the guiding grooves 21. The auxiliary plate 17 is fixedly connected to the long pin 16, and the auxiliary plates 17 are evenly distributed on the surface of the long pin 16. Moreover, the upper surface of the auxiliary plate 17 is an arc-shaped structure, and the dial blocks 18 are fixedly connected at equal angles on the upper surface of the auxiliary plate 17.

[0030] When the working rod 5 drives the external connection plate 12 to rise, the long pin 16 and the upper connection block 19 rise synchronously. At this time, the cross bar 20 drives the upper connection block 19 and the long pin 16 to rotate through the guiding groove 21. When the working rod 5 drives the external connection plate 12 to descend, the cross bar 20 drives the upper connection block 19 and the long pin 16 to rotate back through the guiding groove 21. Repeating the above process, the upper connection 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 dial block 18 also play a role in assisting mixing. The auxiliary plate 17 and the dial block 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 dial block 18 has a better mixing effect, enabling the test sample and the fluorescent reagent to be fully mixed and preventing the test results from deviating.

[0031] Embodiment 3: Different from Embodiment 2, by providing the push rod 24, the working rod 5 and the stirring blade 6 can be in a swinging state, which can also optimize the mixing effect. For example Figures 9-12 As shown, a push rod 24 is connected inside the external connection plate 12 through 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 external connection plate 12. 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 with the push rod 24. A rolling ball 28 is rotatably arranged at the end of the push rod 24.

[0032] A push block 22 is fixedly connected to the surface of the long pin 16, and the surface of the push block 22 is convex. A connecting spring 27 for elastic reset is fixedly connected to the surface of the sliding rod 26, and the other side of the connecting spring 27 is fixedly connected to the inner wall of the external connection plate 12. The other end of the push rod 24 is rotatably connected with an auxiliary ball 25. 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 below the external connection plate 12 is a rubber soft rod; a scraping plate 15 is fixedly connected to the surface of the external connection plate 12.

[0033] When the long pin 16 rotates reciprocally, it will drive the push block 22 to rotate synchronously. At this time, the protruding position 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 sliding 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 sliding rod 26 return to their original positions under the action of the connecting spring 27. Repeating the above process, at this time, the push rod 24 makes a reciprocating linear motion in the horizontal direction. Furthermore, the push rod 24 will intermittently push the working rod 5, causing the lower end (rubber soft rod position) of the working rod 5 to swing, and then the stirring blade 6 can be swung. At this time, the stirring blade 6 has a better material mixing effect, enabling better mixing of the microbial sample and the fluorescent reagent. After deep mixing, the detection of microorganisms can be completed by the laser emitter 7 and the fluorescence detector 8. When the rolling ball 28 is working, it plays a limiting role, enabling better docking of the end of the push rod 24 and the working rod 5.

[0034] During the rotation of the working rod 5 and the stirring blade 6, the working rod 5 drives the external connecting plate 12 and the scraping plate 15 to rotate synchronously. At this time, the scraping plate 15 plays a role in cleaning the inner wall of the detection box 1, so that no material remains on the inner wall of the detection box 1.

[0035] The above is the working process of the entire device, and the content not described in detail in this specification belongs to the prior art well-known to those skilled in the art.

[0036] 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 perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
