Description

Technical Field

[0001] This utility model belongs to the field of laboratory waste liquid recycling technology, and specifically relates to a waste liquid recycling and diversion device for microbial detection. Background Technology

[0002] During microbiological testing experiments, laboratory waste liquid containing microbial residues and chemical reagents is generated. If not properly handled, this waste liquid may cause environmental pollution, microbial spread, and even threaten the health of operators. Therefore, timely and safe recycling of laboratory waste liquid is a crucial aspect of microbiological testing experiments, and effective waste liquid diversion is a prerequisite for safe recycling. Currently, in existing microbiological testing experiments, waste liquid diversion is typically achieved using a relatively simple structure: a flexible tube connects the waste liquid outlet of the microbiological testing instrument to a waste liquid collection tank. Utilizing gravity, the waste liquid generated after testing is diverted through the tube into the collection tank, completing the collection. This tube-based diversion method is widely used in laboratories due to its simple structure, low cost, and ease of operation.

[0003] When the waste liquid in the collection tank reaches the set capacity and needs to be emptied, the operator must first disconnect the hose connected to the collection tank from the tank before moving and emptying it. However, if the waste liquid is still flowing into the collection tank through the hose during this process (e.g., the valve of the testing instrument is not closed in time, waste liquid residue continues to be discharged, or there is waste liquid residue in the hose), separating the hose from the collection tank will cause the undischarged waste liquid in the hose to flow directly from the end of the hose, contaminating the experimental table or floor, and may even cause the operator to come into contact with the waste liquid, which will not only pollute the experimental environment but may also increase the difficulty of subsequent cleaning.

[0004] No effective solutions have yet been proposed to address the problems in the relevant technologies. Utility Model Content

Therefore, they should not be construed as limitations on the utility model.

[0034] Please see Figures 1-6 As shown, this utility model is a waste liquid recovery and diversion device for microbial detection, including a hose 1 and a collection mechanism 2. The hose 1 is fixedly installed with a flange 3 and a connecting pipe 4 at both ends. One end of the connecting pipe 4 is connected to a main pipe 5. The main pipe 5 has a plurality of sliding grooves 501. The sliding grooves 501 are provided with ball bearings 6. A locking mechanism 7 is slidably installed on the outer wall of the main pipe 5. A first connecting ring 8 is fixedly installed on the inner wall of the connecting pipe 4.

[0035] The inner cavity of the connecting pipe 4 is equipped with a first sealing mechanism 9. The first sealing mechanism 9 includes a first horn block 901. A first sealing element 902 is fixedly installed on the outer wall of the first horn block 901. A first movable rod 903 is fixedly installed at one end of the first horn block 901. A first elastic element 904 is sleeved around the first movable rod 903.

[0036] The top of the collecting mechanism 2 is connected to a top pipe 10, a guide ring 11 is fixedly installed on the outer wall of the top pipe 10, and a second connecting ring 12 is fixedly installed on the inner wall of the top pipe 10.

[0037] The inner cavity of the jacking pipe 10 is equipped with a second sealing mechanism 13. The second sealing mechanism 13 includes a second horn block 1301. A second sealing element 1302 is fixedly installed on the outer wall of the second horn block 1301. A second movable rod 1303 is fixedly installed at one end of the second horn block 1301. A second elastic element 1304 is sleeved around the second movable rod 1303.

[0038] The top of the collection mechanism 2 is also equipped with an exhaust mechanism 14;

[0039] The first bracket 15 is fixedly installed in the inner cavity of the connecting pipe 4. The first bracket 15 is slidably installed with the first movable rod 903, and the first elastic element 904 is fixedly installed with the first bracket 15.

[0040] The second bracket 16 is fixedly installed in the inner cavity of the jacking pipe 10. The second bracket 16 is slidably installed with the second movable rod 1303, and the second elastic element 1304 is fixedly installed with the second bracket 16.

[0041] First, connect the hose 1 to the collection mechanism 2. Hold the connecting pipe 4 at one end of the hose 1 with one hand, and pull the locking mechanism 7 towards the connecting pipe 4 with the other hand. During this process, the elastic structure inside the locking mechanism 7 is continuously compressed, and the elastic potential energy increases until the locking mechanism 7 no longer restricts the movement of the balls 6 in each groove 501. Then, insert the main pipe 5 into the top pipe 10. As the main pipe 5 is continuously inserted into the top pipe 10, the guide ring 11 on the top pipe 10 will push the balls 6 to move away from the top pipe 10. After the top pipe 10 is fully inserted into the main pipe 5, the balls 6 will enter the other side of the guide ring 11, and the top pipe 10 will also be located on one side of the connecting pipe 4. Then, release the locking mechanism 7, and the elastic potential energy of the locking mechanism 7 will be released. At this time, the locking mechanism 7 will simultaneously push the balls 6 towards the top pipe 10. The locking mechanism 7 restricts the position of the balls 6 in the groove 501. At this time, the top pipe 10 is restricted in the main pipe 5 by the balls 6 under the action of the guide ring 11.

[0042] Simultaneously, during the insertion of the jacking pipe 10 and the main pipe 5, the first horn block 901 will also come into contact with the second horn block 1301. As the jacking pipe 10 continuously enters the main pipe 5, the first horn block 901 and the second horn block 1301, under the action of each other, cause the first horn block 901 to squeeze the first elastic element 904 (preferably a spring), and bring the first movable rod 903 and the first sealing element 902 (preferably a sealing ring) back towards the inner cavity of the connecting pipe 4. At this time, the first sealing element 902 no longer contacts the first connecting ring 8, thus opening the channel connecting the connecting pipe 4 to the outside. The second horn block 1301 will also squeeze the second elastic element 1304 (preferably a spring), and drive... The second sealing element 1302 (preferably a sealing ring) and the second movable rod 1303 retract toward the inner cavity of the top tube 10, opening the channel for the top tube 10 to communicate with the outside. Since the top tube 10 is also located on one side of the connecting pipe 4 at this time, the inner cavity of the top tube 10 will communicate with the inner cavity of the connecting pipe 4. Then, the flange 3 is connected to the waste liquid outlet of the testing instrument. The waste liquid can enter the hose 1 through the waste liquid outlet, and then enter the connecting pipe 4 and the top tube 10 along the hose 1. Then, it enters the inner cavity of the collection mechanism 2 through the top tube 10. At this time, the exhaust mechanism 14 is in the open state, and the waste liquid continuously flows into the collection mechanism 2. The air in the collection mechanism 2 is discharged through the exhaust mechanism 14 to ensure that the waste liquid smoothly enters the collection mechanism 2.

[0043] When the collection mechanism 2 is full of waste liquid, the locking mechanism 7 is pulled. The locking mechanism 7 no longer restricts the movement of the balls 6 in the slide 501. Then the main pipe 5 can be pulled out from the top pipe 10. During the pulling process, the guide ring 11 on the top pipe 10 can also push several balls 6 to move away from the top pipe 10. Then the balls 6 will no longer restrict the movement of the guide ring 11, and the main pipe 5 can be separated from the top pipe 10. At the same time, the elastic potential energy of the first elastic element 904 is released, and the first elastic element 904 pushes the first The horn block 901, the first movable rod 903, and the first seal 902 move toward the first connecting ring 8 until the first seal 902 abuts against the first connecting ring 8. At this time, the first seal 902 and the first horn block 901 block the opening of the connecting pipe 4 near the main pipe 5, so that the channel connecting the connecting pipe 4 to the outside is closed, and the waste liquid is blocked in the inner cavity of the connecting pipe 4 and the hose 1 to prevent the waste liquid from flowing out from the end of the hose 1 after the hose 1 is separated from the collection mechanism 2, thus contaminating the experimental table or the ground.

[0044] At the same time, the second horn block 1301, the second seal 1302, and the second movable rod 1303 will also move towards the second connecting ring 12 under the action of the second elastic member 1304, so that the second horn block 1301 and the second elastic member 1304 will seal the top opening of the top pipe 10, and then seal the exhaust mechanism 14 to ensure that the waste liquid will not leak due to shaking during transportation.

[0045] In one embodiment, the collection mechanism 2 includes a collection bucket 201, a lid 202 is threaded onto the top of the collection bucket 201, the lid 202 is connected to the top pipe 10, and a transparent plate 203 is installed on the outer wall of the collection bucket 201.

[0046] When the waste liquid needs to be poured out, the cap 202 is turned off to separate the cap 202 from the collection bucket 201, and then the waste liquid in the collection bucket 201 is poured out to the specified position. The experimenter can observe the height of the waste liquid in the collection bucket 201 through the transparent plate 203 on the collection bucket 201.

[0047] In one embodiment, the locking mechanism 7 includes a push ring 701, one end of which has a placement groove 702. A return spring 703 is installed in the placement groove 702, one end of which is fixedly mounted on the push ring 701. The end of the push ring 701 away from the placement groove 702 has an annular groove 704, one side of which is inclined.

[0048] In one embodiment, the slide groove 501 is frustum shaped, and the diameter of the slide groove 501 on the inner wall side of the main pipe 5 is smaller than the diameter on the outer wall side of the main pipe 5. The diameter of the slide groove 501 on the inner wall side of the main pipe 5 is smaller than the diameter of the ball 6, and the diameter of the slide groove 501 on the outer wall side of the main pipe 5 is larger than the diameter of the ball 6.

[0049] The experimenter manually pulls the push ring 701 towards the connecting pipe 4. When the ring groove 704 slides into the area where the balls 6 are located, the inner wall of the push ring 701 no longer contacts the balls 6, allowing the balls 6 to move within their respective grooves 501. Simultaneously, the push ring 701 compresses the return spring 703. Then, the main pipe 5 is inserted into the top pipe 10. During insertion, the guide ring 11 on the top pipe 10 pushes the balls 6 away from the top pipe 10. Once the top pipe 10 is fully inserted into the main pipe 5, the balls 6... The guide ring 11 will enter the other side, and the top tube 10 is also located on one side of the connecting tube 4. Then the push ring 701 is released. Under the action of the return spring 703, the push ring 701 moves away from the connecting tube 4. Since one side of the ring groove 704 is inclined, the inclined part of the ring groove 704 can push several balls 6 to move towards the top tube 10. Then the inner wall of the push ring 701 restricts the position of several balls 6 in each groove 501. At this time, the main tube 5 is restricted in the main tube 5 by several balls 6 under the action of the guide ring 11, thus completing the connection between the main tube 5 and the top tube 10.

[0050] When the main pipe 5 and the jacking pipe 10 need to be separated, the push ring 701 is pulled towards the connecting pipe 4. The inner wall of the push ring 701 no longer restricts the balls 6, pulling the connecting pipe 4 and separating the main pipe 5 and the jacking pipe 10. During the separation process, the other side of the guide ring 11 also pushes the balls 6 to move away from the jacking pipe 10, so that some of the balls 6 enter the ring groove 704 and the other part is still in the sliding groove 501. Thus, the balls 6 no longer restrict the pull-out direction of the guide ring 11 and the jacking pipe 10, thereby enabling the main pipe 5 and the jacking pipe 10 to separate.

[0051] It should be noted that since the diameter of the chute 501 on the inner wall side of the main pipe 5 is smaller than the diameter on the outer wall side of the main pipe 5, and the diameter of the chute 501 on the inner wall side of the main pipe 5 is smaller than the diameter of the ball 6, the ball 6 will not come out from the chute 501 on the inner wall side of the main pipe 5.

[0052] In one embodiment, for the first connecting ring 8, the inner rings of both the first connecting ring 8 and the second connecting ring 12 are inclined.

[0053] The inner ring of the first connecting ring 8 is inclined, which allows the first sealing element 902 to fit better against the inclined surface of the first connecting ring 8, so as to ensure the sealing performance of the first sealing element 902 when sealing the connecting pipe 4. Similarly, the inner ring of the second connecting ring 12 is inclined, which also ensures the sealing performance of the second sealing element 1302 when sealing the top pipe 10.

[0054] In one embodiment, both ends of the guide ring 11 are inclined.

[0055] When inserting or removing the main tube 5, the inclined surfaces at both ends of the guide ring 11 on the top tube 10 can push several balls 6 to move.

[0056] In one embodiment, the exhaust mechanism 14 includes an exhaust pipe 1401, a mesh plate 1402 is mounted on the top of the exhaust pipe 1401, and a connecting cover 1403 is threaded onto the outer wall of the exhaust pipe 1401.

[0057] During the waste liquid recycling stage, the connecting cap 1403 is not screwed onto the exhaust pipe 1401. The exhaust pipe 1401 is connected to the outside through the mesh plate 1402, allowing the gas in the collection tank 201 to be discharged through the mesh plate 1402. When the waste liquid in the collection tank 201 needs to be moved, the connecting cap 1403 is screwed onto the exhaust pipe 1401 to seal the exhaust pipe 1401, ensuring that the waste liquid will not shake and be discharged from the exhaust pipe 1401.

[0058] Working principle: Hold the connecting pipe 4 at one end of the hose 1 with one hand, and pull the push ring 701 towards the connecting pipe 4 with the other hand. When the ring groove 704 slides to the area where several balls 6 are located, the balls 6 can move in their respective slide grooves 501. At the same time, the push ring 701 squeezes the return spring 703. Then, insert the main pipe 5 into the top pipe 10. During the insertion process, the guide ring 11 pushes the balls 6 away from the top pipe 10. After the top pipe 10 is fully inserted into the main pipe 5, the top pipe 10 is located on one side of the connecting pipe 4. Release the push ring 701. Under the action of the return spring 703, the push ring 701 moves away from the connecting pipe 4. The inclined part of the ring groove 704 pushes the balls 6 towards the top pipe 10. Then, the inner wall of the push ring 701 restricts the position of the balls 6 in each slide groove 501. At this time, the main pipe 5 is restricted by the balls 6 under the action of the guide ring 11.

[0059] Meanwhile, during the insertion of the jacking pipe 10 and the main pipe 5, the first horn block 901 and the second horn block 1301 come into contact. As the jacking pipe 10 continues to enter the main pipe 5, the first horn block 901 squeezes the first elastic element 904 and retracts towards the inner cavity of the connecting pipe 4 along with the first movable rod 903 and the first sealing element 902. At this time, the first sealing element 902 no longer contacts the first connecting ring 8, thus opening the channel connecting the connecting pipe 4 to the outside. At the same time, the second horn block 1301 squeezes the second elastic element 130. 4. The second seal 1302 and the second movable rod 1303 retract toward the inner cavity of the jacking pipe 10, so that the channel connecting the jacking pipe 10 with the outside is opened. At this time, the inner cavity of the jacking pipe 10 will be connected with the inner cavity of the connecting pipe 4. Then, the flange 3 is connected to the waste liquid outlet of the testing instrument. The waste liquid enters the hose 1 through the waste liquid outlet, and then enters the connecting pipe 4 and the jacking pipe 10 along the hose 1. Then, it enters the inner cavity of the collection tank 201 through the jacking pipe 10. The gas in the collection tank 201 is discharged from the screen plate 1402.

[0060] The height of the waste liquid in the collection tank 201 is observed through the transparent plate 203. When the collection tank 201 needs to be filled with waste liquid, the push ring 701 is pulled towards the connecting pipe 4. The inner wall of the push ring 701 no longer restricts the balls 6, pulling the connecting pipe 4 and separating the main pipe 5 and the top pipe 10. During the separation process, the other side of the guide ring 11 pushes the balls 6 to move away from the top pipe 10, so that some of the balls 6 enter the ring groove 704. At the same time, the elastic potential energy of the first elastic element 904 is released. The first elastic element 904 pushes the first horn block 901, the first movable rod 903 and the first seal 902 to move towards the first connecting ring 8. Then the first seal 902 abuts against the first connecting ring 8. At this time, the first seal 902 and the first horn block 901 seal the opening of the connecting pipe 4 near the main pipe 5, so that the channel connecting the connecting pipe 4 to the outside is closed, and the waste liquid is sealed in the inner cavity of the connecting pipe 4 and the hose 1.

[0061] Transport the collection bucket 201 to the designated location, unscrew the lid 202 to separate the lid 202 from the collection bucket 201, and then pour the waste liquid in the collection bucket 201 into the designated location.
