The inner side of the air intake is provided with a protective mechanism, which includes a fixed blade, an extended blade and a movable blade. The top surface of the fixed blade is provided with a first limiting strip and a second limiting strip.

[0004] In the process of developing this utility model, the inventors discovered that at least the following problems remain unresolved in the prior art. In the aforementioned case, after sampling is completed using the protective mechanism, the operator rotates the movable blade again, causing the third limiting strip to contact the second abutment. Subsequently, the first abutment abuts against the second limiting strip. The three sets of fixed blades, expanding blades, and movable blades work together to completely cover the opening of the air inlet in a fan shape. However, during use, the opening and closing of the air inlet requires manual control by the operator, resulting in low automation.

[0005] Therefore, we propose a planar bacteria collection device that can solve the above problems. Utility Model Content

[0006] The purpose of this invention is to provide a device for collecting airborne bacteria, which solves the problems mentioned in the background art.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a planar bacteria collection device, comprising a collection cylinder, a piston slidably connected inside the collection cylinder, and a collection mechanism; the collection mechanism is used for air collection operations, the collection mechanism comprising a collection tube, the collection tube being vertically fixedly installed in the middle of the upper surface of the piston, collection ports being symmetrically opened on both sides of the end of the collection tube away from the piston, a guide groove being opened inside the piston, air inlets being opened through both sides of the inner wall at the top of the guide groove, the bottom end of the collection tube communicating with the guide groove, a connecting groove being opened in the middle of the inner wall at the top of the collection cylinder, the collection tube being slidably connected to the connecting groove, and a push handle being vertically fixedly installed in the middle of the bottom side of the piston.

[0018] Please see Figures 1-2 This utility model provides a technical solution: a planar bacteria collection device, including a collection cylinder 1, a piston 11 slidably connected inside the collection cylinder 1, and a collection mechanism; the collection mechanism is used for air collection operations, and includes a collection tube 12, which is vertically fixedly installed in the middle of the upper surface of the piston 11. Collection ports 13 are symmetrically opened on both sides of the end of the collection tube 12 away from the piston 11. A guide groove 14 is opened inside the piston 11, and air inlets 15 are opened through both sides of the inner wall at the top of the guide groove 14. The bottom end of the collection tube 12 communicates with the guide groove 14. A connecting groove 2 is opened in the middle of the inner wall at the top of the collection cylinder 1, and the collection tube 12 is slidably connected to the connecting groove 2. A push handle 16 is vertically fixedly installed in the middle of the bottom side of the piston 11, and the push handle 16 and the collection tube 12 are matched in size to the collection cylinder 1.

[0019] In this technical solution, the operator pulls down the push block 26, which drives the piston 11 to move downwards inside the collection tube 1 via the push handle 16. This pulls the collection tube 12 downwards and deeper into the collection tube 1. Since the collection port 13 at the top of the collection tube 12 is connected to the air inlet 15 through the guide groove 14, the piston 11 can draw air from the pharmaceutical environment into the collection tube 1 through the collection port 13 as it moves downwards. When the piston 11 moves to the bottom of the collection tube 1, the collection port 13 on the outside of the collection tube 12 retracts into the collection tube 1, automatically stopping the collection of airborne bacteria.

[0020] In this embodiment, a fixing block 24 is installed through the middle of the bottom end of the collection tube 1. A cross-shaped fixing groove 25 is opened through the middle of the fixing block 24. The push handle 16 is slidably connected to the fixing groove 25. A push block 26 is fixedly installed at the end of the push handle 16 away from the piston 11. A first fixing hole 27 is opened horizontally at the end of the push handle 16 near the piston 11. A second fixing hole 28 is opened horizontally on one side of the fixing block 24. The push handle 16 and the fixing block 24 are fixedly connected by bolts 29 through the first fixing hole 27 and the second fixing hole 28.

[0021] In this technical solution, the piston 11 can be slidably connected to the push handle 16 through the fixing groove 25 in the middle of the fixing block 24. This can improve the stability of the piston 11 in the collection tube 1. When the piston 11 moves to the bottom of the inside of the collection tube 1, the first fixing hole 27 on the outside of the push handle 16 is aligned with the second fixing hole 28 on the outside of the fixing block 24. The fixing block 24 is fixedly connected to the push handle 16 by the bolt 29 passing through the first fixing hole 27 and the second fixing hole 28. This further limits and fixes the piston 11, preventing the push handle 16 from being accidentally touched during the process of carrying the collection tube 1, which would cause the air sample in the collection tube 1 to leak out.

[0022] In this embodiment, a sealing ring 21 is bonded to the inner wall of the connecting groove 2. The sealing ring 21 is attached to the outer side of the collection tube 12. A sealing groove 22 is provided in the middle of the upper surface of the collection tube 1. A sealing plate 23 is horizontally fixedly installed at the end of the collection tube 12 away from the piston 11. The sealing plate 23 is movably connected to the sealing groove 22.

[0023] In this technical solution, the sealing ring 21 is bonded to the inner wall of the connecting groove 2, which can improve the sealing performance of the connection between the collection tube 12 and the connecting groove 2, and prevent the air sample in the collection tube 1 from leaking out. When the push handle 16 drives the piston 11 to move to the bottom of the inside of the collection tube 1, the collection tube 12 can pull the sealing plate 23 to insert into the sealing groove 22 at the top of the collection tube 1, and further seal the connecting groove 2. Conversely, by pushing the piston 11 to move to the top of the inside of the collection tube 1 through the push handle 16, the sealing plate 23 is pushed out of the sealing groove 22 through the collection tube 12, so that the collection port 13 is moved out of the collection tube 1, and the air sample collected in the collection tube 1 can be discharged.

[0024] When using a planktonic bacteria collection device, the operator pulls down the push block 26, which, through the push handle 16, drives the piston 11 to move downwards inside the collection cylinder 1. This pulls the collection tube 12 downwards and deeper into the collection cylinder 1. Since the collection port 13 at the top of the collection tube 12 is connected to the air inlet 15 through the guide groove 14, air from the pharmaceutical environment can be drawn into the collection cylinder 1 through the collection port 13 as the piston 11 moves downwards. When the piston 11 moves to the bottom of the collection cylinder 1, the collection port 13 on the outside of the collection tube 12 retracts into the collection cylinder 1, automatically stopping the collection of planktonic bacteria from the air. At the same time, the collection tube 12 can pull the sealing plate 23 to insert into the sealing groove 22 at the top of the collection cylinder 1, thus facilitating the collection of bacteria. 1. Sealing is achieved by sliding the fixing groove 25 in the middle of the fixing block 24 with the push handle 16, which can improve the stability of the piston 11 in the collection tube 1. When the piston 11 moves to the bottom of the inside of the collection tube 1, the first fixing hole 27 on the outside of the push handle 16 is aligned with the second fixing hole 28 on the outside of the fixing block 24. The fixing block 24 and the push handle 16 are fixedly connected by the bolt 29 through the first fixing hole 27 and the second fixing hole 28, which further limits and fixes the piston 11. When it is necessary to release the air sample in the collection tube 1, the bolt 29 is removed, and the piston 11 is pushed to the top of the inside of the collection tube 1 by the push handle 16, so that the collection port 13 is moved out of the collection tube 1, and the air sample collected in the collection tube 1 can be discharged.
