Technical Field

[0001] The utility model relates to the technical field of microorganism sampling, in particular to a liquid microorganism sampler. Background Art

[0002] Sampling of microorganisms in samples or specimens in the biological, food, and environmental industries has always been an important issue. Microbial testing requires the evaluation of collection efficiency and activity. Sampling methods and sampling equipment with high collection efficiency can obtain more representative data.

[0003] At present, when sampling liquid microorganisms, the samples are usually extracted directly and then introduced into the sampling bottle. However, the sample is prone to splashing during the introduction process, and the sample exposure time is also long, which will have a certain impact on the activity of the sample. Therefore, it is urgent to design a liquid microorganism sampler to solve the above problems. Utility Model Content

[0008] As a further solution of the utility model: the sampling mechanism includes a sampling tube, the outer wall of the sealing cover is provided with a mounting hole, and the sampling tube is fixedly arranged in the mounting hole, the end of the sampling tube is connected to a suction head, and the suction head is located in the sampling bottle, and the sampling tube is also provided with a suction assembly for sucking the sample into and out of the sampling tube.

[0009] As a further solution of the utility model: the suction assembly includes a piston movably arranged in the sampling tube, a movable rod is fixedly arranged at one end of the piston away from the suction head, and a push-pull plate is fixedly arranged at the top of the movable rod, and the length of the movable rod is greater than the length of the sampling tube.

[0010] As a further solution of the utility model: the cross section of the movable rod is cross-shaped.

[0011] As a further solution of the utility model: the end of the piston close to the suction head is conical, and the piston fits the inner wall of the suction head.

[0012] As a further solution of the utility model: the outer wall of the piston is provided with annular grooves distributed at equal distances, and a sealing ring is arranged in the annular groove, and the sealing ring is in contact with the inner wall of the sampling tube.

[0013] Compared with the prior art, the beneficial effects of the utility model are:

[0014] The utility model provides a liquid microorganism sampler. When it is necessary to collect liquid microorganisms, the sealing cover can be rotated and removed from the sampling bottle. At this time, the sampling mechanism in the sealing cover is also removed together. The liquid microorganisms to be collected can be extracted through the sampling mechanism in the sealing cover. When the extraction is completed, the sampling mechanism in the sealing cover can be placed in the sampling bottle, and the sealing cover can be closed on the top of the sampling bottle to achieve the function of sealing the sampling bottle. The liquid microorganisms collected in the sampling mechanism are then introduced into the sampling bottle. Finally, the sealing cover is tightened so that the sealing cover blocks the top of the sampling bottle, and the liquid microorganisms can be sealed. The sampling operation is completed by sealing it in the sampling bottle. This integrated design can make the sampling process more convenient and can effectively avoid splashing or overflowing of liquid microorganisms introduced into the sampling bottle. The microbial sampler is assembled and produced in an anaerobic environment. The sample diluent in the sampler is a microbial specific active protective liquid produced and filled by hot filling in an anaerobic environment, which effectively eliminates dissolved oxygen in the diluent, so that the collected samples for later use can be stored in a closed anaerobic environment, thereby maximally protecting the anaerobic microorganisms in the sample, solving the activity problem of long-distance transportation of microbial specimens, and achieving better use effect.

[0019] In order to make the purpose, technical solution and advantages of the utility model more clear, the utility model is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the utility model and are not used to limit the utility model.

[0020] like Figure 1-Figure 3 As shown, a liquid microorganism sampler provided by an embodiment of the utility model includes a sampling bottle 1, an outer side of the end of the sampling bottle 1 is provided with an external thread, and the outer side of the external thread is threadedly connected to a sealing cover 2, and also includes:

[0021] The sampling mechanism is arranged in the sealing cover 2 and is used for introducing the collected sample into the sampling bottle 1 .

[0022] When it is necessary to collect liquid microorganisms, the sealing cover 2 can be rotated and removed from the sampling bottle 1. At this time, the sampling mechanism in the sealing cover 2 is also removed. The liquid microorganisms to be collected can be extracted through the sampling mechanism in the sealing cover 2. When the extraction is completed, the sampling mechanism in the sealing cover 2 can be placed in the sampling bottle 1, and the sealing cover 2 can be covered on the top of the sampling bottle 1 to achieve the function of sealing the sampling bottle 1. Then, the liquid microorganisms collected in the sampling mechanism are introduced into the sampling bottle 1, and finally the sealing cover 2 is tightened so that the sealing cover 2 blocks the top of the sampling bottle 1, so that the liquid microorganisms can be sealed in the sampling bottle. Bottle 1 is used to complete the sampling operation. Through this integrated design, the sampling process can be made more convenient, and splashing or overflowing of liquid microorganisms when introduced into the sampling bottle 1 can be effectively avoided. In addition, the microbial sampler is assembled and produced under an anaerobic environment, and the sample diluent in the sampler is a microbial specific active protective liquid produced and filled by hot filling under an anaerobic environment, which effectively eliminates the dissolved oxygen in the diluent, so that the collected samples for later use can be preserved in a closed anaerobic environment, thereby maximally protecting the anaerobic microorganisms in the sample, solving the activity problem of long-distance transportation of microbial specimens, and achieving better use effect.

[0023] As an embodiment of the present invention, please refer to Figure 1 , Figure 2 and Figure 3 The sampling mechanism includes a sampling tube 3. A mounting hole is provided on the outer wall of the sealing cover 2, and the sampling tube 3 is fixedly arranged in the mounting hole. A suction head 4 is connected to the end of the sampling tube 3, and the suction head 4 is located in the sampling bottle 1. A suction component is also provided in the sampling tube 3 for sucking and guiding the sample into and out of the sampling tube 3. When liquid microorganisms need to be collected, the suction head 4 can be placed in the liquid microorganisms to be collected, and then suction can be performed through the suction component, so that the liquid microorganisms can be sucked into the sampling tube 3 along the suction head 4, which is very convenient to use.

[0024] As an embodiment of the present invention, please refer to Figure 1 , Figure 2 and Figure 3The suction assembly includes a piston 7 movably arranged in the sampling tube 3, a movable rod 5 is fixedly arranged at one end of the piston 7 away from the suction head 4, and a push-pull plate 6 is fixedly arranged on the top of the movable rod 5. The length of the movable rod 5 is greater than the length of the sampling tube 3. The movable rod 5 can be driven to move by holding the push-pull plate 6. The movable rod 5 can drive the piston 7 to move in the sampling tube 3, so that the suction head 4 can suck liquid microorganisms, which is very convenient to use.

[0025] As an embodiment of the present invention, please refer to Figure 1 , Figure 2 and Figure 3 The cross section of the movable rod 5 is cross-shaped, which can reduce the overall weight of the sampler and reduce the shaking generated during the movement of the movable rod 5, thereby achieving a better use effect.

[0026] As an embodiment of the present invention, please refer to Figure 1 , Figure 2 and Figure 3 The end of the piston 7 close to the suction head 4 is conical, and the piston 7 fits the inner wall of the suction head 4. When the piston 7 is close to the suction head 4, part of the liquid in the suction head 4 can also be squeezed out, and the use effect is better.

[0027] As an embodiment of the present invention, please refer to Figure 1 , Figure 2 and Figure 3 The outer wall of the piston 7 is provided with annular grooves distributed at equal distances, and a sealing ring 8 is arranged in the annular groove. The sealing ring 8 fits the inner wall of the sampling tube 3, which can enhance the sealing performance of the piston 7 and effectively prevent the sucked liquid microorganisms from penetrating to the top of the piston 7, thereby achieving a better use effect.

[0028] When in use, when it is necessary to collect liquid microorganisms, the sealing cover 2 can be rotated and removed from the sampling bottle 1. At this time, the sampling mechanism in the sealing cover 2 is also removed, and the liquid microorganisms to be collected can be extracted through the sampling mechanism in the sealing cover 2. When the extraction is completed, the sampling mechanism in the sealing cover 2 can be placed in the sampling bottle 1, and the sealing cover 2 can be covered on the top of the sampling bottle 1 to achieve the function of closing the sampling bottle 1, and then the liquid microorganisms collected in the sampling mechanism are introduced into the sampling bottle 1, and finally the sealing cover 2 is tightened so that the sealing cover 2 blocks the top of the sampling bottle 1, so that the liquid microorganisms can be sealed in The sampling operation is completed in the sampling bottle 1. Through this integrated design, the sampling process can be made more convenient, and the splashing or overflowing of liquid microorganisms when introduced into the sampling bottle 1 can be effectively avoided. The microbial sampler is assembled and produced in an anaerobic environment, and the sample diluent in the sampler is a microbial specific active protective liquid produced and filled by hot filling in an anaerobic environment, which effectively eliminates the dissolved oxygen in the diluent, so that the collected samples for later use can be preserved in a closed anaerobic environment, thereby maximally protecting the anaerobic microorganisms in the sample, solving the activity problem of long-distance transportation of microbial specimens, and achieving better use effect.
