Therefore, the integrity of the sediment sample is ensured; and when aerosol in the air is collected by the filter screen, impurities in the air can be isolated, so that the medium is not easy to deteriorate.

Description

Technical Field

[0001] This utility model relates to the technical field of air microbial sampling and detection devices, specifically a multi-channel aerosol sampling and real-time analysis workbench. Background Technology

[0002] Microbial aerosols refer to colloidal systems formed by microorganisms suspended in the air. Nature contains a large amount of microbial aerosols, with those having a particle size of 0.1–20.0 μm being closely related to human health. There are numerous methods for sampling airborne microbial aerosols, but particles smaller than 5 μm are generally considered dangerous particles for airborne diseases.

[0003] Existing microbial aerosol sampling devices typically collect suspended microbial particles from the air directly onto the surface of a sampling medium to measure the number of microbial particles in the air. However, since microbial aerosols are suspended in particulate form, the adsorbed aerosol on the sampling medium surface can easily react with other particles in the air during collection, causing the sampling medium to deteriorate and affecting the measurement results, thus impacting the assessment of air quality. To address this, a multi-channel aerosol sampling and real-time analysis workbench is proposed. Utility Model Content

[0025] Please see Figure 1-5A multi-channel aerosol sampling and real-time analysis workbench includes a support assembly 100, a transfer assembly 200, a fixing assembly 300, a collection assembly 400, and a detection mechanism 500. The support assembly 100 includes a tabletop 110 with rollers 120 on one side. The transfer assembly 200 includes connecting rods 210 on the other side of the tabletop 110, symmetrically distributed on the outer wall of the tabletop 110, with handles 220 on the outer wall of each connecting rod. Four rollers 120 are symmetrically distributed at the bottom of the tabletop 110, and the handles 220 are primarily made of natural rubber. The rollers 120 provide support for the equipment during operation. The stable supporting force facilitates the later transfer of the equipment. The handle 220, made of rubber, improves the grip when the worker pushes the connecting rod 210 to move the equipment. The fixing component 300 includes a trapezoidal connector 310 mounted on the top of the tabletop 110. A bracket 320 is provided on one side of the trapezoidal connector 310, and a screw 340 is provided on the other side. A drive pump 330 is mounted on one end of the bracket 320, and a pump shaft 350 is mounted on the other end. An inclined guide plate 370 is provided on the other end of the pump shaft 350. The collecting component 400 includes a housing 410 mounted on the top of the tabletop 110. A positioning groove 450 is formed on the outer wall of the housing 410. The inner surface of the positioning groove 450... The unit is equipped with a baffle 420, and a tube platform 430 is installed on the top of the baffle 420. A sedimentation component 440 is installed on the inner wall of the tube platform 430. A tilting discharge platform 460 is installed on the inner wall of the housing 410. A reset component 470 is installed on the inner wall of the housing 410. A detection mechanism 500 is installed on the inner wall of the housing 410. One end of a rod positioning frame 360 ​​is installed on the outer wall of the detection mechanism 500. The other end of the rod positioning frame 360 ​​is connected to a pump shaft 350. The pump shaft 350 passes through the housing 410. The pump shaft 350 and the inclined guide plate 370 are integrated devices. Trapezoidal connectors 310 are symmetrically distributed on the top of the table 110. When the equipment starts working, the support 320 can be stably connected to the table through the threaded connection between the screw 340 and the table 110. At the top of plate 110, the drive pump 330 can directly drive the inclined guide plate 370 to slide at the top of the detection mechanism 500 via the pump shaft 350. During the sliding of the inclined guide plate 370, the rod positioning frame 360 ​​can support the pump shaft 350, thereby effectively improving the stability of the inclined guide plate 370 during movement. The sedimentation assembly 440 includes a conical guide 441 disposed on the inner wall of the tube platform 430. The inner wall of the conical guide 441 is provided with a filter screen 442. The conical guide 441 is sleeved with the tube platform 430, and the filter screen 442 is slidably connected to the conical guide 441. The conical guide 441 penetrates the housing 410. Through the sliding connection between the conical guide 441 and the filter screen 442,This design facilitates easy cleaning and replacement of the filter screen 442 by workers. Furthermore, the connection between the conical guide 441 and the tube platform 430 allows for direct replacement of the conical guide 441 during equipment maintenance, ensuring the equipment's usability. The reset assembly 470 includes an alignment shell 471 mounted on the inner wall of the housing 410. One end of a shaft 472 is mounted on the inner wall of the housing 410, and the other end of the shaft 472 is provided with an inclined guide plate 370. A positioning ring 473 and a tension spring 474 are provided on the outer wall of the shaft 472. A baffle 420 and a positioning groove 450 are slidably connected. The tilting unloading platform 460 is located directly below the conical guide 441, and rotates between the tilting unloading platform 460 and the inner wall of the housing 410. In this connection, when airborne aerosols are deposited through filter screen 442, they fall directly onto the tilting discharge platform 460. When the aerosol deposits accumulate to a certain level, they are discharged downwards through the slot on the tilting discharge platform 460 due to inertia. The shaft 472 and positioning ring 473 are integrated, and the tension spring 474 is located on the inner wall of the alignment shell 471. The diameter of the positioning ring 473 is larger than the diameter of the tension spring 474, and the shaft 472 and alignment shell 471 are slidably connected. When the shaft 472 is under force, it slides within the alignment shell 471. During this sliding process, the tension spring 474 contracts, and after the inclined guide plate 370 moves, the pushing and pulling force released by the deformation of the tension spring 474 resets the inclined guide plate 370.

[0026] Working principle: When the device is used, aerosols in the air will be precipitated through the filter screen 442. After precipitation, they will fall directly onto the tilting discharge table 460 through the conical guide 441. When the aerosol precipitate accumulates to a certain extent, it will be discharged downward through the slot on the tilting discharge table 460 under the action of inertia. During the downward discharge process, the drive pump 330 will provide driving force to control the pump shaft 350 to extend and retract. During the extension and retraction process, the inclined guide plate 370 will clamp and guide the aerosol precipitate to the top of the detection mechanism 500.
