As shown in fig. 1, 5-6, the connecting member 100 includes a bearing plate 110 and a blocking plate 120, the periphery of the bearing plate 110 is fixedly connected to the inside of one end of the lowest end of the three-way pipe 1, the bearing plate 110 is divided into two parts with different sizes and areas by the blocking plate 120, it should be noted that the shapes and sizes of the bearing plate 110 and the blocking plate 120 are not particularly limited, and the blocking plate 120 can meet the requirement that the first floating block 210 and the second floating block 220 float up and down; the loading plate 110 is provided with a first through pipe 130 and a second through pipe 140, the first through pipe 130 and the second through pipe 140 are respectively arranged at two sides of the blocking plate 120, the first through pipe 130 is provided with a first through hole 131 penetrating the loading plate 110 and a second through hole 132 parallel to the loading plate 110, and the second through pipe 140 is provided with a third through hole 141 penetrating the loading plate 110 and a fourth through hole 142 parallel to the loading plate 110; the second through hole 132 and the fourth through hole 142 are arranged on one side of the bearing plate 110 far away from the cup body 2, the first through hole 131 is communicated with the second through hole 132, the third through hole 141 is communicated with the fourth through hole 142, the floating piece comprises a first floating block 210 and a second floating block 220 which are connected with each other, and the first floating block 210 and the second floating block 220 are arranged on one side of the bearing plate 110 far away from the cup body 2; the first floating block 210 is provided with a first sliding block 211, the first sliding block 211 is connected with the first through hole 131 in a sliding and sealing mode, the second floating block 220 is provided with a second sliding block 221, and the second sliding block 221 is connected with the third through hole 141 in a sliding and sealing mode; it should be noted that, when the water collection amount on the bearing plate 110 is sufficient, the floating member can rise, so as to drive the first sliding block 211 or the second sliding block 221 to rise, and then the first sliding block 211 slides upwards from the first through hole 131, so as to communicate the first through hole 131 with the second through hole 132, and communicate the three-way pipe 1 with the cup body 2, so that the condensed water can be retained in the cup body 2; the second slider 221, the third through hole 141 and the fourth through hole 142 are arranged in the same way, and at this time, because the areas of the bearing plate 110 where the first through hole 131 and the second through hole 132 are located are different, the volumes of condensed water accumulated on the bearing plate 110 are different, and the pressures to the first through hole 131 and the third through hole 141 are different, so that the three-way pipe 1 and the cup body 2 are prevented from being blocked because the first through hole 131, the second through hole 132, the third through hole 141 and the fourth through hole 142 are sealed by water after the floating block rises. Of course, in other embodiments, the pressure of the passing condensed water can be controlled by adding the first through hole 131 and the third through hole 141 with different apertures, so as to prevent blocking; it should be noted that, the first floating block 210 and the second floating block 220 are fixedly connected to each other, so that when any one floating block floats upwards, the second floating block is driven to float upwards, the first through hole 131 and the third through hole 141 are opened simultaneously, and regardless of the inside floating block floating caused by excessive condensed water in the area, the first through hole 131 and the third through hole 141 are opened simultaneously finally, so that the condensed water flows into the cup body 2, thereby further reducing the phenomenon that excessive condensed water is collected in two areas with different areas on the bearing plate 110, and further reducing the leakage efficiency.

Specifically, the method comprises the following three using processes:

an initial stage: when no condensed water exists in the pipeline, the first floating block 210 drives the first sliding block 211 to descend due to gravity to block the first through hole 131 and the second through hole 132 in the connecting piece 100, and the second floating block 220 drives the second sliding block 221 to descend due to gravity to block the third through hole 141 and the fourth through hole 142 in the connecting piece 100, so that the three through holes are not communicated with the cup body 2 at the moment.

The process stage is as follows: when condensed water appears in the pipeline, due to buoyancy, the first floating block 210 and the second floating block 220 which are fixedly connected with each other drive the first sliding block 211 and the second sliding block 221 to move upwards by utilizing buoyancy, so that the first through hole 131, the second through hole 132, the third through hole 141 and the fourth through hole 142 are opened, the third through hole is communicated with the cup body 2, the condensed water can flow into the cup body 2 from the third through hole along the second through hole 132 and the fourth through hole 142, along with the reduction of the condensed water in the third through hole, the buoyancy of the first floating block 210 and the second floating block 220 is reduced, the first through hole 131, the second through hole 132, the third through hole 141 and the fourth through hole 142 are lowered, and the first through hole 131, the second through hole 132, the third through hole; the three through holes are not communicated with the cup body 2, so that the condensed water containing germs cannot disperse the germs into the three-way pipe 1 to cause secondary infection.

And (5) finishing: because the increase and the reduction of comdenstion water, the floating block can be continuous to rise and descend, because the gathering speed of comdenstion water can not be too fast, so, when the floating block descends, can take off cup 2, fall the comdenstion water.

In some embodiments, in order to ensure that the cup body 2 can be effectively self-sealed, the cup body 2 is sealed after the cup body 2 is taken down, and the cross infection phenomenon of medical staff is avoided; cup 2 comprises a sealing member 300 and a loading member 400, wherein sealing member 300 is used for connecting sealing member 400 and tee 1, and loading member 400 is used for loading condensed water. Specifically, the sealing element 300 comprises an annular connecting part 320, and a blocking part 310 and an anti-falling part 330 which are arranged on two sides of the annular connecting part 320, wherein a first external thread is arranged on the outer surface of the annular connecting part 320 and is in threaded connection with one end of the three-way pipe 1, and two fifth through holes 311 are arranged on the blocking part 310; the loading member 400 comprises a connecting part 410 and a loading part 420 which are fixedly connected with each other, wherein an annular groove 411 is arranged on the connecting part 410, the anti-falling part 330 is arranged in the annular groove 411, and the height of the annular groove 411 is greater than the thickness of the anti-falling part 330, so that the anti-falling part 330 can move up and down in the annular groove 411; the outer surface of the connecting part 410 is provided with a second external thread which is in threaded connection with the annular connecting part 320, and the outer surface refers to the position of the largest annular diameter of the connecting part 410; the connecting portion 410 is provided with two sixth through holes 412; the rotation directions of the first external thread and the second external thread are opposite, and it should be noted that, as shown in fig. 4, the relationship between the fifth through hole 311 and the sixth through hole 412 is that, when the connecting portion 410 and the blocking portion 310 are tightened, the fifth through hole 311 and the sixth through hole 412 should be arranged in a staggered manner, and are matched with each other two by two, so that the sealing effect is achieved.

The working principle is as follows: as shown in fig. 2-3;

during installation: when the cup body 2 needs to be fastened on the three-way pipe 1, the sealing element 300 only needs to be aligned with the three-way pipe 1 and then the loading element 400 is rotated, the sealing element 300 is driven to rotate through the loading element 400, and the specific mode is as follows, because the rotating directions of the first external thread and the second external thread are opposite, when the loading element 400 moves downwards relative to the sealing element 300, the second external thread is reversed; at this time, the first external thread rotates forward, so that the sealing element 300 is screwed relatively to the tee 1, and the loading element 400 cannot be completely separated from the sealing element 300 due to the matching of the annular groove 411 and the anti-falling part 330, but is screwed downwards and always with the sealing element 300, so that enough force is provided to be transmitted to the sealing element 300, and the sealing element 300 can be screwed with the tee 1 better; when the sealing element 300 is screwed with the three-way pipe 1, a certain gap exists between the connecting part 410 and the blocking part 310, and the three-way pipe 1 is communicated with the cup body 2 by matching the arrangement of the fifth through hole 311 and the sixth through hole 412, so that the purpose of flowing condensed water is achieved.

When the device is disassembled: the second external thread is rotated forward, due to the resistance, when the loading piece 400 is rotated, the loading piece 400 and the sealing piece 300 move relatively, at the moment, the loading piece 400 moves upward relative to the sealing piece 300, after the connecting part 410 is abutted to the blocking part 310, the rotation is stopped, and at the moment, the fifth through hole 311 and the sixth through hole 412 are dislocated and cannot be communicated; then, after the connecting part 410 is completely abutted to the blocking part 310, the rotary loading part 400 starts to drive the sealing element 300 to move, so that the first external thread is reversed, the sealing element 300 is separated from the three-way pipe 1, the dismantling work is completed, the cup body 2 after the dismantling is completed, the blocking part 310 of the sealing element 300 and the connecting part 410 of the loading part 400 are still in an abutting state, the purpose of blocking condensed water is achieved, and when the condensed water needs to be poured out, the loading part 400 only needs to be rotated relative to the sealing element 300.

In some embodiments, in order to ensure the sealing performance between the carrier 400 and the sealing member 300, as shown in fig. 1, an elastic sealing washer 500 is disposed between the separation preventing part 330 and the connecting part 410; the edge of the anti-separation part 330 is connected with the bottom of the annular groove 411 in a rotary sealing manner, when the application is in a loading process, that is, when a certain gap exists between the connecting part 410 and the blocking part 310, the connecting part 410 should move towards the anti-separation part 330 at this time, and the elastic sealing washer 500 is pressed to ensure sealing; it should be noted that the elastic sealing washer 500, the manner of rotary sealing connection, is conventional knowledge of those skilled in the art and will not be explained in too much.

In some embodiments, as shown in fig. 7, in order to prevent the first slider 211 from completely separating from the first through hole 131 due to the instantaneous excessive condensation of the first float 210 or the second float 220. Therefore, the three-way pipe is further provided with an abutting part, the abutting part comprises a baffle 630, a threaded rod 620 and a handle 610, the baffle 630 is arranged inside the three-way pipe 1, the handle 610 is arranged outside the three-way pipe 1, the threaded rod 620 is in threaded connection with the pipe wall of the three-way pipe 1, the baffle 630 can abut against the first floating block 210 or the second floating block 220 under the rotation motion of the threaded rod 620, on one hand, the abutting part limits the floating distance of the first floating block 210 and the second floating block 220, and the first sliding block 211 cannot fall off from the first through hole 131; on the other hand, when the cup body 2 needs to be taken down for a long time, the handle 610 only needs to be rotated to drive the threaded rod 620 to rotate, so that the baffle 630 completely abuts against the first floating block 210 and is completely pressed, the baffle cannot rise along with buoyancy, and the first through hole 131, the second through hole 132, the third through hole 141 and the fourth through hole 142 are prevented from being blocked for a long time, and sealing is completed.
