DETAILED DESCRIPTION

[0025] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further explained below in conjunction with specific implementation methods.

After removal, the movable seat 17 is driven upward by the fixed column 14 to be taken out.

[0027] In this embodiment, a threaded seat 13 is fixed on the connecting seat 4, an internal thread is formed on the inner wall of the supporting seat 6, and the supporting seat 6 is rotatably installed inside the threaded seat 13 through the internal thread. A cavity 16 is formed inside the collecting barrel 1, and a movable seat 17 is movably installed inside the cavity 16. A conical seat 18 is fixed inside the movable seat 17, and a collecting seat 19 is fixed at one end of the conical seat 18. Filter holes are formed on the collecting seat 19 and the conical seat 18, and the diameter of the filter holes on the collecting seat 19 is smaller than the diameter of the filter holes on the conical seat 18. A fixing column 14 is fixed on the top of the movable seat 17, and one end of the fixing column 14 is movably installed on the inner wall of the sealing seat 8. The conical seat 18 and the collecting seat 19 cooperate to facilitate the specimen to slide down quickly. After the specimen enters the collecting seat 19, it is convenient to contact the specimen with the liquid inside the cavity 16 for short-term storage.

[0028] In this embodiment, a movable disk 23 is movably installed inside the pressurizing seat 7, an arc-shaped groove 25 is opened on one side of the movable disk 23, a filter plate 33 is fixedly installed on the arc-shaped groove 25, the movable disk 23 is installed inside the pressurizing seat 7 through a torsion spring shaft, a baffle 21 and a limit plate 24 are fixedly installed on the inner wall of the pressurizing seat 7, respectively, the baffle 21 and the limit plate 24 are movably contacted with the movable disk 23, the baffle 21 is opened with an opening 22, the torsion spring shaft includes a rotating tube 34, a rotating column 35 is movably installed inside the rotating tube 34, one end of the rotating column 35 is fixed on the inner wall of the pressurizing seat 7, a torsion spring 36 is fixed between the rotating column 35 and the rotating tube 34, the movable disk 23 is always tilted to one side through the torsion spring shaft, and after the movable disk 23 tilts, the baffle 21 and the limit plate 24 provide limiting support for the movable disk 23.

[0029] In this embodiment, the inside of the exhaust pipe 9 and the intake pipe 10 are both movably installed with a cleaning ring 31, a fixed pipe 32 is fixed to one side of the cleaning ring 31, one end of the fixed pipe 32 is fixed to the ring seat 12, the inside of the exhaust pipe 9 and the intake pipe 10 are both opened with an annular groove 28, a tension mechanism 29 is fixed inside the annular groove 28, a movable column 30 is fixed to one end of the tension mechanism 29, one end of the movable column 30 is fixed to the ring seat 12, and the exhaust pipe 9 and the intake pipe 10 are both movably installed with The air pipe 26 has a support tube 27 fixed on it, and a fixing ring is fixed on the inner wall of the support tube 27. The fixing ring cooperates with the limiting ring 11, and the ring seat 12 is in active contact with one end of the air pipe 26. The tension mechanism 29 is a tension spring, and the tension spring drives the ring seat 12 to move in the direction of the pressurizing seat 7. However, after the air pipe 26 squeezes the ring seat 12 in the later stage, the reaction force generated by the tension mechanism 29 pushes the air pipe 26 to move outward, and the outward movement of the air pipe 26 realizes the limiting fixation of the support tube 27.

[0030] When the device is in use, the exhaust pipe 9 and the air inlet pipe 10 are first installed between the air pipe 26 of the negative pressure device. When the air pipe 26 is installed, the support pipe 27 on the air pipe 26 is installed on the exhaust pipe 9. By squeezing the support pipe 27, the fixing ring on the support pipe 27 is respectively installed on the exhaust pipe 9 and the air inlet pipe 10 through the limit ring 11. One end of the air pipe 26 squeezes the ring seat 12, and the ring seat 12 squeezes the tension mechanism 29 through the movable column 30. The reaction force generated by the tension mechanism 29 pushes the ring seat 12 to move outward. The outward movement of the ring seat 12 pushes the air pipe 26 to move. The movement of the air pipe 26 makes the fixing ring at the support pipe 27 always connected with the limit ring 11 The fixing ring 11 contacts the support tube 27 to seal, which is convenient for the rapid installation of the air pipe 26 in the early stage. After the installation is completed, the air pipe 26 attracts and collects the sample. The sample enters the interior of the pressurized seat 7 through the air inlet pipe 10. The gas flows through the filter plate 33 and the opening 22. When the impurities in the gas pass through the filter plate 33, they are filtered and adsorbed. The larger sample falls into the movable seat 17 inside the collection barrel 1. The diameter of the filter hole on the collection seat 19 is smaller than the diameter of the filter hole on the conical seat 18. The sample slides on the conical seat 18 to the collection seat 19 for collection. Before collection, the liquid is injected into the interior of the collection barrel 1 through the injection pipe 2. Liquid is injected, and the contact between the liquid and the sample increases the storage time of the sample. When the sample needs to be taken out, liquid is injected through the injection tube 2, and the discharge tube 3 drains the water. The liquid is injected through the injection tube 2 to make the collection bucket 1 generate a rotating centrifugal force. The rotating centrifugal force of the liquid drives the objects inside the conical seat 18 and the collection seat 19 to rotate and rinse, and the tissues and blood clots inside the conical seat 18 and the collection seat 19 are rinsed. After rinsing, the conical seat 18 and the collection seat 19 are taken out upward. When the device is not disassembled, the sealing seat 8 is separated from the connecting tube 20 after rotation. After separation, the fixed column 14 drives the movable seat 17 to move upward, and the movable seat 17 moves to the movable disk 23. The side of the movable seat 17 enters into the arc groove 25, and the movable seat 17 moves inside the arc groove 25 to scratch one side of the filter plate 33, and the scratching is used to scrape and clean the substances adsorbed on the filter plate 33. The conical seat 18 and the collecting seat 19 are in a conical state, which can effectively prevent the sample from falling from the side when moving up and down. When not in use in the later stage, the air pipe 26 is removed from the exhaust pipe 9 and the air inlet pipe 10. After removal, the ring seat 12 moves outward, and the ring seat 12 drives the cleaning ring 31 to move inside the exhaust pipe 9 and the air inlet pipe 10 through the fixed pipe 32. When the cleaning ring 31 moves, the impurities remaining on the inner wall of the interface are scraped outward, which is convenient for the later cleaning and disinfection of the pressurized seat 7.
