Description
Technical Field
[0001] The present application relates to the technical field of strain mixing, and in particular to a detection strain mixing device for aseptic sampling. Background Art
[0002] In the study of microbiology and biotechnology, aseptic sampling technology is crucial to ensure the accuracy and reliability of experimental results. Aseptic sampling refers to taking a certain amount of sample from the sample to be tested for analysis or processing without introducing external contaminants. This technology is widely used in many fields such as medicine, food, and environment, and is of great significance for preventing the spread of pathogens, ensuring product quality, and protecting the ecological environment.
[0003] Traditional aseptic sampling methods usually rely on manual operation, such as using a sterile syringe or pipette to directly sample from the sample to be tested. However, this method is easily affected by human factors during the operation, such as improper operation, cross-contamination of pollutants, etc., which leads to unreliable sampling results. Therefore, this patent needs to be upgraded and modified based on the existing technology. Utility Model Content
[0004] In response to the shortcomings of the prior art, the present application provides a detection strain mixing device for sterile sampling, which overcomes the shortcomings of the prior art and aims to solve the problem that traditional sterile sampling methods usually rely on manual operation, such as using a sterile syringe or pipette to directly sample from the sample to be tested. This method is easily affected by human factors during the operation, such as improper operation, cross-contamination of contaminants, etc., which leads to the unreliability of the sampling results.
[0005] To achieve the above-mentioned purpose, the present application provides the following technical solutions: a detection strain mixing device for sterile sampling, comprising a mixing chamber, a sampling layer is fixedly connected to the outer side of the mixing chamber, a rotating ring is rotatably connected to the inside of the sampling layer, a fixed tooth is fixedly connected to the outer side of the rotating ring, the end of the fixed tooth is tightly fitted to the inner wall of the sampling layer, a gear ring is provided on the inner wall of the rotating ring, a vortex spring is provided inside the rotating ring, the vortex spring is fixedly connected to the outer side of the mixing chamber, the vortex spring is a counterclockwise spiral structure, the end of the vortex spring is against the inside of the gear ring, a sampling port is provided on the outer side of the mixing chamber, and a sample outlet is provided at the bottom of the sampling layer.
[0006] By adopting the above technical scheme, a plurality of fixed teeth are provided, which are fixedly connected to the outside of the rotating ring in a circular arrangement order, and the sampling port structure is equal to the structure of the fixed tooth interval, and the number of teeth inside the gear ring is the same as the number of fixed teeth. During the sampling process, the mixed liquid will flow into the interval of the fixed teeth through the sampling port, and then the rotating ring is rotated, and the mixed liquid will enter the interval area of the next fixed tooth through the sampling port. Since the fixed teeth are equidistantly arranged, the water content of each interval area is the same, and the sampling content can be determined according to the rotation angle. Since the vortex spring against the inside of the gear ring is a counterclockwise spiral structure, it is ensured that the rotating ring can only rotate counterclockwise, thereby driving the sampling solution to move downward counterclockwise, and then discharged through the sample outlet, thereby preventing the sampling process from causing contamination to the mixed liquid.
[0007] As a preferred technical solution of the present application, a switch shaft is rotatably connected just above the sampling layer, one end of the switch shaft penetrates into the mixing chamber, and a baffle is fixedly connected to the end of the switch shaft, which fits tightly to the inner wall of the mixing chamber.
[0008] By adopting the above technical solution, the baffle is driven to rotate by rotating the switch shaft, thereby closing the sampling port through the baffle, thereby preventing the mixed liquid from flowing into the fixed tooth interval through the sampling port.
[0009] As a preferred technical solution of the present application, a sampling area is fixedly connected to the bottom of the sampling layer, and a collecting groove is slidably connected inside the sampling area.
[0010] By adopting the above technical solution, when sampling, the collection tank is inserted into the sampling area, and sampling is performed by rotating the rotating ring. During the rotation of the rotating ring, the sampled water will be discharged into the collection tank through the sample outlet. After the sampling is completed, the collection tank is directly taken out to detect and analyze the sample water.
[0011] As a preferred technical solution of the present application, one side of the rotating ring is tightly fitted to the outside of the mixing chamber, and a rubber pad is provided on the outside of the mixing chamber at the position of the rotating ring. The other side of the rotating ring is tightly fitted to the inside of the sampling layer, and a rubber pad is provided at the fitting position between the inner side of the sampling layer and the rotating ring, and a knob is fixedly connected to the outside of the rotating ring.
[0012] By adopting the above technical solution, a rubber pad is provided at the outer connection of the rotating ring to prevent water leakage during the sampling process from causing inaccurate sampling content.
[0013] As a preferred technical solution of the present application, a motor is fixedly connected to the top of the mixing bin, a driving end of the motor passes through the top of the mixing bin and is fixedly connected to a turntable, and a stirring blade is provided at the bottom of the turntable.
[0014] By adopting the above technical solution, a plurality of stirring blades are arranged in a circle at the bottom of the turntable, the turntable is driven to rotate by a motor, and the stirring blades are driven to rotate by the turntable, thereby accelerating the mixing of strains.
[0015] As a preferred technical solution of the present application, a feed port is fixedly connected to one end of the top of the mixing bin, a feed valve is fixedly arranged on the outside of the feed port, a discharge port is fixedly connected to one side of the mixing bin, and a discharge valve is fixedly arranged on the outside of the discharge port.
[0016] By adopting the above technical solution, the strain solution to be mixed can be discharged into the mixing bin through the feed port, and the strain solution after mixing can be discharged through the discharge port.
[0017] Beneficial effects of this application:
[0018] 1. In the utility model, the sampling solution moves in the counterclockwise direction through the counterclockwise spiral structure of the rotating ring and the vortex spring and is discharged through the sample outlet. This one-way flow design helps to prevent contamination of the mixed solution during the sampling process and maintain the sterility of the sample.
[0019] 2. In the present invention, the device can ensure that the amount of sample taken in each rotation during the sampling process is determined by the fixed teeth on the rotating ring. Since the fixed teeth are arranged at equal intervals, the water content of each interval area is the same, so the sampling amount can be accurately controlled by controlling the rotation angle of the rotating ring.

During the sampling process, the mixed liquid will flow into the interval of the fixed teeth 13 through the sampling port 14, and then the rotating ring 12 will be rotated, and the mixed liquid will enter the interval area of the next fixed tooth 13 through the sampling port 14. Since the fixed teeth 13 are equidistantly arranged, the water content of each interval area is the same, and the sampling content can be determined according to the rotation angle. Since the vortex spring 16 against the inside of the gear ring 15 is a counterclockwise spiral structure, it is ensured that the rotating ring 12 can only rotate counterclockwise, thereby driving the sampling solution to move downward counterclockwise, and then discharged through the sample outlet 17, thereby preventing the sampling process from causing contamination to the mixed liquid.
[0028] In this embodiment, if Figure 1 - Figure 5 As shown, a switch shaft 8 is rotatably connected just above the sampling layer 6, one end of the switch shaft 8 passes through the interior of the mixing chamber 1, and a baffle 20 is fixedly connected to the end of the switch shaft 8. The baffle 20 fits tightly to the inner wall of the mixing chamber 1, and the baffle 20 is driven to rotate by rotating the switch shaft 8, thereby closing the sampling port 14 through the baffle 20, thereby blocking the mixed liquid from flowing into the interior of the fixed tooth 13 through the sampling port 14.
[0029] In this embodiment, if Figure 1 - Figure 5As shown, a sampling area 9 is fixedly connected to the bottom of the sampling layer 6, and a collecting tank 10 is slidably connected inside the sampling area 9. When sampling, the collecting tank 10 is inserted into the sampling area 9, and sampling is performed by rotating the rotating ring 12. During the rotation of the rotating ring 12, the sampled water will be discharged into the collecting tank 10 through the sample outlet 17. After the sampling is completed, the collecting tank 10 is directly taken out to detect and analyze its sample water.
[0030] In this embodiment, if Figure 1 - Figure 5 As shown, one side of the rotating ring 12 fits tightly against the outside of the mixing chamber 1, a rubber pad is provided on the outside of the mixing chamber 1 at the position of the rotating ring 12, the other side of the rotating ring 12 fits tightly against the inside of the sampling layer 6, a rubber pad is provided at the position where the inner side of the sampling layer 6 and the rotating ring 12 fit, and a knob 7 is fixedly connected to the outside of the rotating ring 12. By providing a rubber pad at the connection on the outside of the rotating ring 12, water leakage during the sampling process can be prevented, which may lead to inaccurate sampling content.
[0031] In this embodiment, if Figure 1 - Figure 5 As shown, a motor 11 is fixedly connected to the top of the mixing bin 1, and a turntable 18 is fixedly connected after the driving end of the motor 11 passes through the top of the mixing bin 1. A stirring blade 19 is provided at the bottom of the turntable 18, wherein a plurality of stirring blades 19 are arranged in a circle at the bottom of the turntable 18. The turntable 18 is driven to rotate by the motor 11, and the stirring blades 19 are driven to rotate by the turntable 18, thereby accelerating the mixing of the strains.
[0032] In this embodiment, if Figure 1 - Figure 5 As shown, a feed port 2 is fixedly connected to one end of the top of the mixing bin 1, a feed valve 4 is fixedly arranged on the outside of the feed port 2, a discharge port 3 is fixedly connected to one side of the mixing bin 1, a discharge valve 5 is fixedly arranged on the outside of the discharge port 3, the strain solution to be mixed can be discharged into the mixing bin 1 through the feed port 2, and the strain solution after mixing can be discharged through the discharge port 3.
[0033] Working principle: When in use, the switch shaft 8 located just above the sampling layer 6 is rotated so that the baffle 20 fixed at the end of the switch shaft 8 fits tightly against the inner wall of the mixing chamber 1, thereby closing the sampling port 14, and the strain solution to be mixed is discharged into the mixing chamber 1 through the feed port 2, and then the motor 11 is started, and the turntable 18 is driven to rotate by the motor 11, thereby driving the stirring blade 19 at the bottom of the turntable 18 to rotate, and the strain solution to be mixed begins to be stirred. When the strains are fully mixed, the switch shaft 8 is rotated in the opposite direction so that the baffle 20 no longer closes the sampling port 14, and the mixed liquid flows into the mixing chamber 1 through the sampling port 14. The mixed liquid will enter the interval area of the next fixed tooth 13 through the sampling port 14, and the sampling content can be formulated according to the required rotation angle. When it is rotated to the required sampling content, the switch shaft 8 is rotated again to make the baffle 20 fixed at the end of the switch shaft 8 fit tightly against the inner wall of the mixing chamber 1, thereby closing the sampling port 14 again, and then continue to rotate the rotating ring 12, and the sampled water is driven downward by the rotating ring 12 until it passes through the sample outlet 17 and enters the collecting tank 10 to complete the sampling.
