Description

Technical Field

[0001] The utility model relates to the technical field of samplers, in particular to a planktonic bacteria biological sampler. Background Art

[0002] Planktonic bacteria refer to living microbial particles suspended in the air. These microorganisms include viruses, rickettsia, bacteria, fungi and protozoa. Since these microorganisms are usually very small and cannot be seen directly by the naked eye, a sampler is needed to collect and sample the planktonic bacteria. Based on the principle of particle impact, these living microorganisms undergo a dynamic rehydration process during the culture process and grow at a high speed, thereby obtaining results faster.

[0003] When the current planktonic bacteria sampler is not in use, a matching cover is required to block the vent to prevent outside air from entering the sampler. When the sampler is in use, the staff must pick up the cover and place it on the table, which poses a risk of it falling or being lost.

[0004] When the planktonic bacteria sampler collects planktonic bacteria, the planktonic bacteria enter the sampling bottle placed on the sampler through the ventilation holes. During long-term use, the ventilation holes are easily blocked by dust due to their small size, and staff need to clean them frequently. Utility Model Content

[0005] The purpose of the utility model is to provide a planktonic bacteria biological sampler to solve the problems raised in the above background technology.

When a sampling vessel is to be placed on the top of the placing table 2, the rotating connecting shell 3 can be taken down together with the rotating shell 4, and a mounting plate 5 is rotatably connected to the inner wall of the rotating shell 4. A vent 16 is opened at the center point of the mounting plate 5, and a vent plate 9 is bolted to the inner wall of the vent 16. Under the action of the vent plate 9, external wind can circulate, and at the same time, larger bodies can be blocked. The top of the mounting plate 5 is provided with an isosceles hexagonal groove 6, and a blocking mechanism 7 is provided on one side of the isosceles hexagonal groove 6. The blocking mechanism 7 includes a slider 71. The number of the sliders 71 is six. The surface of the slider 71 is slidably connected to the inner wall of the isosceles hexagonal groove 6. The top of the slider 71 is bolted with a triangular fence 72. The triangular fence 72 is arranged in a circular array with the center point of the vent 16. When the triangular fences 72 are fully in contact with each other, the vent 16 can be blocked. A fixing rod 73 is fixedly connected to one side of the top of the triangular fence 72. Sliding bars are provided at six locations on the top of the rotating shell 4. The inner wall of the sliding groove 8 is slidably connected with the surface of the fixed rod 73. When the sampler is used, the staff rotates the rotating shell 4. When the rotating shell 4 rotates, the position of the sliding groove 8 can be changed. When the position of the sliding groove 8 changes, the fixed rod 73 can be moved. When the fixed rod 73 moves, the triangular fence 72 can be moved. When the triangular fence 72 moves, the slider 71 can be moved. When the triangular fence 72 is fully unfolded, the air vent 16 can be unblocked. A fixed block 10 is bolted to one side of the inner wall of the rotating shell 4. When the rotating shell 4 rotates, the fixed block 10 can be driven to move. A cleaning mechanism 11 is provided inside the rotating shell 4. When the fixed block 10 moves, the cleaning mechanism 11 can move. Under the action of the fixed block 10, the parts inside the cleaning mechanism 11 can be fixed to prevent them from falling. A baffle 13 is provided on one side of the inner wall of the connecting shell 3. The baffle 13, the cleaning mechanism 11, and the ventilation plate 9 are used together. When the cleaning mechanism 11 moves, the parts inside the cleaning mechanism 11 can be squeezed under the action of the baffle 13, so that the parts inside the cleaning mechanism 11 are compressed. Under this design, the cleaning mechanism 11 can clean the ventilation holes on the ventilation plate 9.

[0024] The cleaning mechanism 11 includes an airbag 111, one side of the surface of the airbag 111 is fixedly connected to the inner wall of the fixed block 10, one end of the airbag 111 is fixedly connected to one side of the surface of the baffle 13, when the fixed block 10 moves, the airbag 111 can be compressed under the action of the baffle 13, one side of the top of the airbag 111 is connected to a pipe rack 112, when the airbag 111 is compressed, the air inside the airbag 111 can enter the inside of the pipe rack 112 and the pipe rack 112 can be moved, and the air outlets of the pipe rack 112 are connected to each other. There is a nozzle 113, and the air inside the pipe rack 112 can be sprayed out from the nozzle 113, and the movable nozzle 113 can be moved when the pipe rack 112 moves. The nozzle 113 is designed to be inclined with the center of the ventilation plate 9. In this design, the air sprayed from the nozzle 113 can clean the ventilation hole of the one-way valve 15. Six places on the surface of the pipe rack 112 are fixedly connected with a ring 12, and one side of the surface of the ring 12 is bolted to one side of the inner wall of the rotating shell 4. Under the action of the ring 12, the pipe rack 112 can be auxiliary supported.

[0025] One side of the surface of the airbag 111 is connected to an inflation tube 14, and one side of the surface of the inflation tube 14 is connected to a one-way valve 15. The one-way valve 15 penetrates one side of the inner wall of the rotating shell 4 and is bolted to each other at the penetration. After the staff uses the sampler, they reverse the rotating shell 4 to return the sampler to its original state, and then open the one-way valve 15. Under the action of the one-way valve 15, external air can enter the interior of the inflation tube 14, and the air inside the inflation tube 14 can enter the interior of the airbag 111, thereby inflating the airbag 111.

[0026] It is worth noting that the technical features such as the sampler body 1 proposed in this technical solution should be regarded as prior art. The specific structure, working principle, and possible control method and spatial arrangement method of these technical features can be selected according to the conventional methods in the field, and this technical solution will not be further elaborated.

[0027] Working principle: When using the sampler, the staff rotates the rotating shell 4, and when the rotating shell 4 rotates, the position of the sliding groove 8 can be changed. When the position of the sliding groove 8 changes, the fixed rod 73 can be moved. When the fixed rod 73 moves, the triangular fence 72 can be driven to move. When the triangular fence 72 moves, the slider 71 can be moved. When the triangular fence 72 is fully unfolded, the air vent 16 can be unblocked, so that the external air carries the floating bacteria into the sampler from the ventilation plate 9, so that the sampling dish placed on the placement table 2 can collect the floating bacteria. When the rotating shell 4 rotates, the fixed block 10 can be driven to move. When the fixed block 10 moves, the baffle 1 3, the airbag 111 can be compressed. During the compression of the airbag 111, the air inside the airbag 111 can enter the inside of the pipe rack 112. The air inside the pipe rack 112 can be ejected from the nozzle 113 to clean the ventilation holes of the ventilation plate 9. After using the sampler, the reverse rotating shell 4 can make the triangular railings 72 completely contact each other, so that the sampler is in a sealed state. The staff opens the one-way valve 15. Under the action of the one-way valve 15, the external air can enter the inside of the inflation tube 14, and the air inside the inflation tube 14 enters the inside of the airbag 111, so that the air inside the airbag 111 is replenished for the next use.
