[0002] Ventilators are very common medical devices. When a patient is seriously ill and cannot breathe on their own, they need to be assisted or forced to breathe. During the operation of the ventilator, condensed water will be generated in the pipeline of the ventilator. The accumulation of condensed water in the pipeline will affect the stability of the gas flow and gas pressure in the pipeline, and it is also easy to breed bacteria. Therefore, it is necessary to set a condensed water collection device on the pipeline of the ventilator to collect the condensed water in the pipeline of the ventilator.

[0003] The current condensate collection device is manually installed on the ventilator pipeline, and it is necessary to ensure that the condensate collection device is at the lowest point of the ventilator pipeline so that the condensate in the ventilator pipeline can automatically flow into the condensate collection device under the action of gravity.

[0021] See also Figures 1 to 6 The embodiment of the present invention provides a ventilator pipeline 100 with a condensed water collection function, which is applied to a ventilator. The ventilator pipeline comprises a collection mechanism 30, a Y-shaped pipe mechanism 20 and two breathing connecting pipes 10.

[0022] The breathing connection tube 10 is a corrugated hose. During the operation of the ventilator, condensed water will be generated in the breathing connection tube 10. The Y-shaped tube mechanism 20 is connected between the two breathing connection tubes 10 and the collecting mechanism 30. The Y-shaped tube mechanism 20 connects the two breathing connection tubes 10 with the collecting mechanism 30 so that the condensed water in the breathing connection tube 10 can flow into the collecting mechanism 30 through the Y-shaped tube mechanism 20. The collecting mechanism 30 is used to collect and store the condensed water generated in the breathing connection tube 10.

[0023] The Y-shaped tube mechanism 20 includes a connecting member 21 , a rotating assembly 22 and a locking assembly 23 .

[0024] The connecting member 21 includes a mounting ring shell 211 and two connecting tubes 212. The mounting ring shell 211 is roughly in the shape of a flat wheel, and the connecting tube 212 is in the shape of a circular tube. The mounting ring shell 211 is vertically arranged and has a central axis O extending in the horizontal direction. The mounting ring shell 211 is provided with an inner cavity 213. The two connecting tubes 212 are respectively arranged on the back and front sides of the mounting ring shell 211. The connecting tubes 212 are connected to the inner cavity 213, and the two connecting tubes 212 are respectively connected to the two breathing connecting tubes 10. Specifically, the end of the connecting tube 212 away from the mounting ring shell 211 can be inserted into a port of the breathing connecting tube 10, or can be sleeved on the outer periphery of one end of the breathing connecting tube 10.

[0025] The rotating assembly 22 is connected to the mounting ring shell 211 and can rotate on the mounting ring shell 211 with the central axis O as the rotation axis. The collecting mechanism 30 is connected to the rotating assembly 22 and communicates with the inner cavity 213 .

[0026] The locking assembly 23 is disposed between the rotating assembly 22 and the mounting ring shell 211. The locking assembly 23 has an open state and a locked state. When the locking assembly 23 is in the open state, the collecting mechanism 30 can follow the rotating assembly 22 and rotate on the mounting ring shell 211 with the central axis O as the rotation axis. When the locking assembly 23 is in the locked state, the rotating assembly 22 cannot rotate so that the relative position of the collecting mechanism 30 and the mounting ring shell 211 is fixed.

[0027] When the above-mentioned ventilator pipeline 100 with condensed water collection function is in use, one of the breathing connection tubes 10 is used to connect the ventilator, and the other breathing connection tube 10 is used for the patient to inhale and exhale. Before turning on the ventilator, the operator first opens the locking assembly 23. Since the collection mechanism 30 is rotatably connected to the mounting ring shell 211 through the rotating assembly 22, the collection mechanism 30 can automatically rotate to the lowest position of the breathing connection tube 10 through the rotating assembly 22 under the action of its own gravity, and then the locking assembly 23 is locked to keep the relative position of the collection mechanism 30 and the mounting ring shell 211 fixed, and finally the ventilator is turned on. Since the collection mechanism 30 is at the lowest position of the breathing connection tube 10 at this time, the condensed water generated in the breathing connection tube 10 can flow into the inner cavity 213 as much as possible, and continue to flow into the collection mechanism 30 for storage, thereby improving the collection efficiency and collection effect of the collection mechanism 30 on the condensed water in the breathing connection tube 10, and the above-mentioned operation of adjusting the collection mechanism 30 to the lowest position does not require manual adjustment by the operator. Therefore, the ventilator pipeline 100 with the condensed water collection function can fully collect the condensed water in the breathing connecting tube 10, and has the beneficial effects of high collection efficiency of the condensed water in the breathing connecting tube 10 and simple and convenient installation and operation.

[0028] See also Figure 2 and Figure 6In some embodiments, the end of the connecting pipe 212 away from the mounting ring shell 211 is bent and extended in a direction away from the collecting mechanism 30. Through the above arrangement, the end of the breathing connecting pipe 10 connected to the connecting pipe 212 can be lower than the end of the breathing connecting pipe 10 away from the connecting pipe 212, so that the condensed water in the breathing connecting pipe 10 flows into the connecting pipe 212 and the inner cavity 213 under the action of gravity.

[0029] See also Figure 2 , Figure 3 , Figure 6 and Figure 7 In some embodiments, the rotating assembly 22 includes a rotating outer sleeve 221 and a rotating inner ring 222. The rotating outer sleeve 221 is rotatably sleeved on the outer circumference of the mounting ring shell 211, and the connecting tube 212 is inserted through the rotating outer sleeve 221. The inner side wall of the mounting ring shell 211 is provided with a mounting ring groove 214, and the rotating inner ring 222 is rotatably embedded in the mounting ring groove 214. The bottom of the mounting ring shell 211 is provided with a clearance port 215 communicating with the inner cavity 213, and the clearance port 215 extends along the circumference of the mounting ring shell 211. The rotating inner ring 222 is provided with an inner connecting tube 224 communicating with the inner cavity 213, and the inner connecting tube 224 is roughly cylindrical, and the inner connecting tube 224 is inserted through the clearance port 215 and extends to the outside of the inner cavity 213. The rotating outer sleeve 221 is provided with an outer connecting tube 223, which is roughly cylindrical, and the inner connecting tube 224 is inserted into the outer connecting tube 223 and fits with the inner side wall of the outer connecting tube 223. Through the above arrangement, since the outer connecting tube 223 is sleeved outside the inner connecting tube 224 and the two fit each other, the rotating outer sleeve 221 can be synchronously rotated with the rotating inner ring 222 with the central axis O of the mounting ring shell 211 as the rotation axis. During the above rotation process, the inner connecting tube 224 moves in the clearance opening 215 along the extension direction of the clearance opening 215, and the rotation range of the inner connecting tube 224 is limited by the extension length of the clearance opening 215.

[0030] The collecting mechanism 30 includes a collecting bottle 31, and the collecting bottle 31 includes a bottle body 311 and a connecting sleeve 312 connected to the bottle body 311. The bottle body 311 is roughly cylindrical, and the connecting sleeve 312 is roughly cylindrical. The top of the bottle body 311 gradually narrows and is connected to one end of the connecting sleeve 312. The bottle body 311 has a collecting cavity 313, and the connecting sleeve 312 is connected to the collecting cavity 313. The connecting sleeve 312 is threadedly sleeved on the outer circumference of the outer connecting cylinder 223 to connect the collecting cavity 313 with the inner cavity 213. The collecting bottle 31 can be made of a transparent material or a translucent material so that the operator can observe the liquid level of the condensed water collected in the collecting bottle 31.

[0031] Through the above arrangement, when the locking assembly 23 is in the open state, the collecting mechanism 30, under the action of its own gravity, will drive the rotating outer sleeve 221 and the rotating inner ring 222 to rotate synchronously with the central axis O of the mounting ring shell 211 as the rotating axis, so that the collecting bottle 31 of the collecting mechanism 30 is always in the lowest position of the breathing connecting tube 10, so that the condensed water in the breathing connecting tube 10 can flow into the connecting tube 212 and the inner cavity 213 under the action of gravity, and finally flow into the collecting cavity 313 of the collecting bottle 31 through the inner connecting tube 224 for storage, so as to fully collect the condensed water in the breathing connecting tube 10.

[0032] See also Figure 1 , Figure 5 and Fig. 9 In some embodiments, the rotating inner ring 222 is further provided with a branch hose 43 that is in communication with the inner cavity 213. The branch hose 43 passes through the rotating outer sleeve 221 and extends to the outside of the connector 21. A valve 44 and an end cover 45 are provided on the branch hose 43. The valve 44 is used to control the on and off of the branch hose 43, so as to prevent the condensed water in the inner cavity 213 from spraying out from the branch hose 43 when the end cover 45 is opened. The end cover 45 is sleeved on one end of the branch hose 43 away from the rotating inner ring 222, and blocks the port of the branch hose 43. The end cover 45 can be opened and closed, and when the end cover 45 is closed, it can prevent foreign impurities from entering the branch hose 43. At least part of the structure of the end cover 45 is connected to the branch hose 43, so that the end cover 45 will not be separated from the branch hose 43 when it is opened, thereby preventing the end cover 45 from being accidentally lost. Through the above arrangement, when the end cover 45 is opened, the branch hose 43 can be connected to a negative pressure suction device (not shown in the figure), and then the valve 44 is opened. The condensed water in the inner cavity 213 can be sucked out through the branch hose 43 using the negative pressure suction device.

[0033] See also Fig.11 and Fig.12In some embodiments, the breathing connection tube 10 is provided with a branch hose 43 connected thereto, and the branch hose 43 is provided with a valve 44 and an end cap 45. The valve 44 is used to control the on and off of the branch hose 43, so as to prevent the condensed water in the breathing connection tube 10 from being sprayed out from the branch hose 43 when the end cap 45 is opened. The end cap 45 is sleeved on the end of the branch hose 43 away from the rotating inner ring 222, and blocks the port of the branch hose 43. The end cap 45 can be opened and closed, and when the end cap 45 is closed, it can prevent foreign impurities from entering the branch hose 43. At least part of the structure of the end cap 45 is connected to the branch hose 43, so that the end cap 45 will not be separated from the branch hose 43 when it is opened, thereby preventing the end cap 45 from being accidentally lost. Through the above arrangement, when the end cap 45 is opened, the branch hose 43 can be connected to the negative pressure aspirator (not shown in the figure), and then the valve 44 is opened, and the condensed water in the breathing connection tube 10 can be sucked out through the branch hose 43 by the negative pressure aspirator.

[0034] It should be noted that, in some embodiments, the ventilator circuit 100 with the condensed water collection function may be provided with both a collection mechanism 30 and a branch hose 43. The collection mechanism 30 may be used to collect the condensed water in the breathing connecting tube 10. The branch hose 43 may be used in conjunction with a negative pressure suction device to further collect the condensed water in the breathing connecting tube 10. In other embodiments, the ventilator circuit 100 with the condensed water collection function may be provided with only a collection mechanism 30 or only a branch hose 43. Both the collection mechanism 30 and the branch hose 43 may be provided separately to collect the condensed water in the breathing connecting tube 10.

[0035] See also Figure 6 and Figure 7In some embodiments, a water collecting funnel 225 is provided on the inner side wall of the inner connecting tube 224. The water collecting funnel 225 is roughly in the shape of a cone. The water collecting funnel 225 has a first end with a larger opening and a second end with a smaller opening. The first end is connected to the inner side wall of the inner connecting tube 224, and the second end is provided with a water outlet 226. The water outlet 226 connects the inner cavity 213 with the collecting cavity 313. A first blocking member 227 is inserted on the water collecting funnel 225. The first blocking member 227 is used to block the water outlet 226. The first blocking member 227 includes a first blocking head 2271 and a first connecting rod 2272. The first blocking head 2271 is a block structure with a larger upper portion and a smaller lower portion. The first blocking head 2271 is located in the water collecting funnel 225, and the maximum diameter of the first blocking head 2271 is greater than the diameter of the water outlet 226. Therefore, the first blocking head 2271 cannot pass through the water outlet 226. The first connecting rod 2272 is a round rod, one end of which is connected to the first plugging head 2271, and the other end passes through the water outlet 226 and extends into the collecting chamber 313. The diameter of the first connecting rod 2272 is smaller than the diameter of the water outlet 226, so the first connecting rod 2272 can move freely in the water outlet 226.

[0036] The collecting mechanism 30 further includes a column 32 and a mounting frame 33. The column 32 is vertically arranged at the center of the inner bottom surface of the bottle body 311, and the mounting frame 33 is arranged at the top of the column 32. A first top rod 34 is vertically arranged on the mounting frame 33, and the first top rod 34 is arranged opposite to the first connecting rod 2272, and the diameter of the first top rod 34 is smaller than the diameter of the water outlet 226.

[0037] When the collecting bottle 31 is separated from the external connection tube 223, the first plugging head 2271 fits with the water outlet 226 to block the water outlet 226, and the condensed water in the inner cavity 213 cannot flow out of the inner cavity 213 from the water outlet 226. When the collecting bottle 31 is connected to the external connection tube 223, the first push rod 34 pushes the first connecting rod 2272 vertically upward to separate the first plugging head 2271 from the water outlet 226, and the condensed water in the inner cavity 213 can flow into the collecting bottle 31 from the water outlet 226.

[0038] Through the above arrangement, during normal use, the collecting bottle 31 is connected to the external connecting tube 223. At this time, the first push rod 34 pushes the first connecting rod 2272 vertically upward, and the first plugging head 2271 is separated from the water outlet 226, so that the condensed water in the inner cavity 213 can flow smoothly into the collecting bottle 31. When too much condensed water is collected in the collecting bottle 31, the operator can remove the collecting bottle 31 from the external connecting tube 223 to replace the collecting bottle 31. When the collecting bottle 31 is separated from the external connecting tube 223, the first top rod 34 loses its supporting effect on the first connecting rod 2272, and the first blocking piece 227 falls vertically under the action of gravity, so that the first blocking head 2271 fits with the water outlet 226 to block the water outlet 226. At this time, the condensed water in the inner cavity 213 cannot flow out of the inner cavity 213 from the water outlet 226, and external impurities and germs cannot enter the inner cavity 213 from the water outlet 226, thereby ensuring the sanitary environment in the breathing connecting tube 10.

[0039] In some embodiments, the mounting frame 33 includes a sleeve 331 and a mounting column 332. The sleeve 331 is a cylindrical structure with one end open, and the sleeve 331 is sleeved on the top of the column 32. The mounting column 332 is roughly a cylindrical structure, and the mounting column 332 is connected to the side of the sleeve 331 away from the column 32. The diameter of the mounting column 332 is smaller than the diameter of the sleeve 331. A blocking plate 333 is movably sleeved on the mounting column 332, and the blocking plate 333 is roughly a circular plate structure. A vertically arranged support spring 334 is connected between the blocking plate 333 and the sleeve 331. One support spring 334 can be provided, or multiple support springs 334 can be provided around the outer circumference of the mounting column 332. A second push rod 2241 is provided at one end of the inner connecting tube 224 away from the rotating inner ring 222, and the projection of the second push rod 2241 in the vertical direction falls on the surface of the blocking plate 333. One second push rod 2241 may be provided, or a plurality of second push rods 2241 may be provided around the circumference of the inner connecting tube 224 .

[0040] When the collecting bottle 31 is separated from the external connection tube 223, the support spring 334 holds the blocking plate 333 against the inner wall of the bottle body 311 to separate the upper and lower sides of the blocking plate 333. When the collecting bottle 31 is connected to the external connection tube 223, the second push rod 2241 pushes the blocking plate 333 toward the sleeve tube 331 to separate the blocking plate 333 from the inner wall of the bottle body 311. At this time, the support spring 334 is in a compressed state, and the condensed water flowing out of the inner cavity 213 can flow into the bottle body 311 from the gap between the blocking plate 333 and the inner wall of the bottle body 311.

[0041] Through the above-mentioned arrangement, during normal use, the collecting bottle 31 is connected to the external connecting tube 223. At this time, the second top rod 2241 pushes the sealing plate 333 toward the direction close to the sleeve tube 331 to separate the sealing plate 333 from the inner wall of the bottle body 311. At this time, the condensed water flowing out of the inner cavity 213 can flow into the interior of the bottle body 311 from the gap between the sealing plate 333 and the inner wall of the bottle body 311 to ensure that the collecting bottle 31 can collect the condensed water smoothly. When too much condensed water is collected in the collecting bottle 31, the operator can remove the collecting bottle 31 from the external connecting tube 223 to replace the collecting bottle 31. When the collecting bottle 31 is separated from the external connecting tube 223, the second top rod 2241 loses its supporting effect on the sealing plate 333. The sealing plate 333 moves vertically upward under the action of the supporting spring 334 until the sealing plate 333 fits against the inner wall of the bottle body 311. At this time, the condensed water in the bottle body 311 below the sealing plate 333 is blocked by the sealing plate 333 and cannot flow out from the opening of the bottle body 311, so that the condensed water in the collecting bottle 31 can be avoided from accidentally spilling out during the replacement of the collecting bottle 31, which is safer and more hygienic.

[0042] See also Figure 6 , Figure 7 , Fig. 9 and Fig.10 In some embodiments, the mounting column 332 is provided with a water receiving chamber 3321 opposite to the water outlet 226, and the first push rod 34 is vertically arranged on the inner bottom wall of the water receiving chamber 3321. The collecting mechanism 30 also includes a water collecting cup 35, a connecting block 36, a tension spring 37 and a floating plate 38. The water collecting cup 35 is a cylindrical structure with one end open. The connecting block 36 is a block structure, and the connecting block 36 is connected to the outer wall of the water collecting cup 35 and is close to the bottom wall of the water collecting cup 35. One end of the tension spring 37 is fixedly connected to the outer wall of the water collecting cup 35, and the tension spring 37 is closer to the cup mouth of the water collecting cup 35 than the connecting block 36. The floating plate 38 is roughly in the shape of a circular plate, and the floating plate 38 is sleeved on the column 32 and can move along the axial direction of the column 32. The floating plate 38 is spaced apart from the water collecting cup 35 , the floating plate 38 is spaced apart from the bottom wall of the bottle body 311 , the outer wall of the floating plate 38 is spaced apart from the inner wall of the bottle body 311 , and the density of the floating plate 38 is less than the density of water.

[0043] The mounting frame 33 further includes a connecting bracket 335, a connecting shaft 336, and a shunt pipe 337 connected to the water receiving chamber 3321. The connecting bracket 335 is arranged on the outer wall of the sleeve 331, and the connecting block 36 is rotatably connected to the connecting bracket 335 through the connecting shaft 336 to realize the rotatable connection between the water collecting cup 35 and the sleeve 331. The axial direction of the connecting shaft 336 is perpendicular to the axial direction of the column 32. One end of the tension spring 37 away from the water collecting cup 35 is fixedly connected to the outer wall of the sleeve 331. One end of the shunt pipe 337 is connected to the sleeve 331, and the other end extends to the top of the water collecting cup 35. The shunt pipe 337 is used to drain the condensed water in the water receiving chamber 3321 to the water collecting cup 35.

[0044] When the condensed water in the water collecting cup 35 does not reach the specified liquid level, the tension spring 37 pulls the water collecting cup 35 to keep the water collecting cup 35 in a vertical state. When the condensed water in the water collecting cup 35 reaches the specified liquid level, the torque generated by the water collecting cup 35 and the condensed water therein can overcome the torque of the tension spring 37, so that the water collecting cup 35 turns over with the connecting shaft 336 as the axis, thereby pouring the condensed water in the water collecting cup 35 onto the floating plate 38. It should be noted that the above-mentioned "specified liquid level" refers to the minimum liquid level of the condensed water in the water collecting cup 35 required for the water collecting cup 35 and the condensed water therein to overcome the torque of the tension spring 37 and turn over. When the condensed water in the water collecting cup 35 reaches the specified liquid level, the torque generated by the water collecting cup 35 and the condensed water therein can overcome the torque of the tension spring 37, so that the water collecting cup 35 turns over with the connecting shaft 336 as the axis, thereby pouring the condensed water in the water collecting cup 35 onto the floating plate 38. On the contrary, when the condensed water in the water collecting cup 35 does not reach the specified liquid level height, the water collecting cup 35 is kept in a vertical state under the tension of the tension spring 37 .

[0045] Through the above arrangement, during normal use, condensed water flows out of the water outlet 226 and falls into the water receiving chamber 3321, and then flows into the water collecting cup 35 through the diverter pipe 337. In the early stage of water collection, due to the tension of the tension spring 37, the water collecting cup 35 can maintain a vertical state. As the condensed water in the water collecting cup 35 gradually increases, when the condensed water in the water collecting cup 35 reaches a specified liquid level, the torque generated by the water collecting cup 35 and the condensed water inside it can overcome the torque of the tension spring 37. At this time, the water collecting cup 35 can be turned over with the connecting shaft 336 as the axis, so that the condensed water in the water collecting cup 35 is poured out onto the floating plate 38. The water collecting cup 35 that pours out the condensed water will be pulled back to a vertical state by the tension spring 37 to continue collecting the condensed water. The condensed water poured out of the water collection cup 35 falls on the surface of the floating plate 38, which will generate an impact force on the floating plate 38. The above-mentioned impact force acts on the column 32 to drive the collection bottle 31 to swing and shake. The swing and shaking of the collection bottle 31 will drive the Y-tube mechanism 20 and the breathing connection tube 10 to swing and shake, so that the condensed water remaining in the folds of the breathing connection tube 10 is further discharged into the inner cavity 213, so as to further collect the condensed water in the breathing connection tube 10. The condensed water falling on the floating plate 38 can flow from the gap between the floating plate 38 and the inner side wall of the bottle body 311 to the bottom of the floating plate 38, and as the condensed water under the floating plate 38 gradually increases, the condensed water under the floating plate 38 can push the floating plate 38 to move vertically upward along the column 32, so as to ensure that the floating plate 38 can always float on the surface of the condensed water to receive the condensed water poured out from the collection cup.

[0046] In some embodiments, the floating plate 38 includes a connecting plate 381 and a floating ring 382. The connecting plate 381 is generally a circular plate structure, and the connecting plate 381 is a hard plate, such as hard plastic, etc. The connecting plate 381 is used to receive the condensed water poured out of the water collection cup 35, and the connecting plate 381 can be movably sleeved on the column 32. The floating ring 382 is generally a circular ring structure, such as a rubber ring, etc. The floating ring 382 is sleeved on the outer periphery of the connecting plate 381, and the outer side wall of the floating ring 382 is spaced from the inner side wall of the bottle body 311. The density of the connecting plate 381 is less than the density of water, and the density of the floating ring 382 is less than the density of the connecting plate 381.

[0047] Through the above arrangement, the condensed water poured out from the water collection cup 35 falls on the hard connecting plate 381, which can increase the impact force on the floating ring 382, ​​thereby increasing the swing amplitude of the collection bottle 31, so as to discharge the condensed water remaining in the folds of the breathing connecting tube 10 as much as possible. The condensed water falling on the connecting plate 381 can flow into the bottom of the floating plate 38 from the gap between the floating ring 382 and the inner wall of the bottle body 311. As the condensed water under the floating plate 38 gradually increases, since the density of the connecting plate 381 is less than the density of water, and the density of the floating ring 382 is less than the density of the connecting plate 381, the overall density of the floating plate 38 is less than the density of water, and the floating plate 38 can always be on the surface of the condensed water in the bottle body 311 under the action of buoyancy, so as to continue to receive the condensed water poured out from the water collection cup 35. In addition, since the density of the floating ring 382 is less than the density of the connecting plate 381, the floating ring 382 can improve the stability and reliability of the floating plate 38 floating on the surface of the condensed water.

[0048] See also Figure 6 , Figure 7 and Figure 8 In some embodiments, a water outlet 338 is provided at one end of the shunt pipe 337 away from the sleeve 331, and the axial direction of the water outlet 338 is in the vertical direction. A second blocking member 339 is inserted into the shunt pipe 337, and the second blocking member 339 is used to block the water outlet 338. The second blocking member 339 includes a second blocking head 3391 and a second connecting rod 3392. The second blocking head 3391 is a block-shaped structure with a larger upper portion and a smaller lower portion. The second blocking head 3391 is located in the shunt pipe 337, and the maximum diameter of the second blocking head 3391 is greater than the diameter of the water outlet 338, so the second blocking head 3391 cannot pass through the water outlet 338. The second connecting rod 3392 is a roughly cylindrical structure, one end of which is connected to the second plugging head 3391, and the other end passes through the water outlet 338 and extends to the outside of the diverter pipe 337. The diameter of the second connecting rod 3392 is smaller than the diameter of the water outlet 338, so the second connecting rod 3392 can move freely in the water outlet 338. A third top rod 351 is vertically arranged on the inner bottom wall of the water collecting cup 35, and the third top rod 351 is arranged opposite to the second connecting rod 3392, and the diameter of the third top rod 351 is smaller than the diameter of the water outlet 338. A guiding slope 3393 is arranged at one end of the second connecting rod 3392 away from the second plugging head 3391, and the guiding slope 3393 is inclined relative to the end surface of the second connecting rod 3392 away from the second plugging head 3391 in a direction close to the second plugging head 3391.

[0049] When the water collecting cup 35 is in the flipped state, the third push rod 351 is separated from the second connecting rod 3392, and the second plugging head 3391 is fitted with the water outlet 338 to block the water outlet 338, and the condensed water in the shunt pipe 337 cannot flow out from the water outlet 338. When the water collecting cup 35 is transformed from the flipped state to the vertical state, the guiding slope 3393 is used to guide the third push rod 351 to the end face of the second connecting rod 3392 away from the second plugging head 3391, so that the third push rod 351 lifts the second connecting rod 3392 upward, thereby separating the second plugging head 3391 from the water outlet 338, and the condensed water in the shunt pipe 337 can flow out from the water outlet 338 into the water collecting cup 35.

[0050] Through the above arrangement, when the condensed water in the water collecting cup 35 does not reach the specified liquid level, the water collecting cup 35 is in a vertical state, at which time the third push rod 351 lifts the second connecting rod 3392 upwards to separate the second plugging head 3391 from the water outlet 338, and the condensed water in the diverter pipe 337 flows out from the water outlet 338 into the water collecting cup 35. As the condensed water in the water collecting cup 35 increases, when the condensed water in the water collecting cup 35 reaches the specified liquid level, the water collecting cup 35 flips over, at which time the third push rod 351 separates from the second connecting rod 3392, and the second plugging member 339 falls freely under the action of gravity, so that the second plugging head 3391 fits with the water outlet 338 and blocks the water outlet 338, and at this time the condensed water in the diverter pipe 337 cannot flow out from the water outlet 338. After the condensed water in the water collecting cup 35 is discharged, the tension spring 37 pulls the water collecting cup 35 to rotate from the flipped state to the vertical state. In the above process, the end of the third push rod 351 will first contact the guiding slope 3393, and will move along the guiding slope 3393 toward the end face of the second connecting rod 3392 away from the second plugging head 3391. In the above movement process, the third push rod 351 will continuously push the second connecting rod 3392 upward, thereby causing the second plugging head 3391 to continuously move upward. Finally, when the water collecting cup 35 returns to the vertical state, the end face of the third push rod 351 is in contact with the end face of the second connecting rod 3392 away from the second plugging head 3391 (such as Figure 8 The third push rod 351 stably supports the second plugging member 339 so that the second plugging head 3391 is completely separated from the water outlet 338, and the water outlet 338 is opened again, so that the water collection cup 35 can continue to collect the condensed water flowing out of the water outlet 338.

[0051] In some embodiments, the sleeve 331 is rotatably sleeved on the top of the column 32. The column 32 is also sleeved with a one-way rotating ring 39, which is connected to the column 32 through a ratchet mechanism (not shown in the figure) so that the one-way rotating ring 39 can only rotate relative to the column 32 in a specified direction. The above-mentioned "specified direction" depends on the specific installation direction of the ratchet of the ratchet mechanism.

[0052] A first mounting block 391 is provided on the outer side wall of the one-way rotating ring 39, and a second mounting block 352 is provided on the bottom end of the outer side wall of the water collecting cup 35. A ball head connecting rod 40 is provided between the first mounting block 391 and the second mounting block 352, and a first connecting ball 41 and a second connecting ball 42 are provided at opposite ends of the ball head connecting rod 40. At least part of the structure of the first connecting ball 41 is embedded in the interior of the first mounting block 391 and can rotate relative to the first mounting block 391. At least part of the structure of the second connecting ball 42 is embedded in the interior of the second mounting block 352 and can rotate relative to the second mounting block 352.

[0053] When the water collecting cup 35 is in the flipped state, the water collecting cup 35 drives the one-way rotating ring 39 to rotate a unit angle in the specified direction through the ball head connecting rod 40. The above-mentioned "unit angle" depends on the specific size of the ratchet of the ratchet mechanism. It can be understood that each time the water collecting cup 35 is flipped, the one-way rotating ring 39 can rotate a unit angle in the specified direction.

[0054] Through the above arrangement, when the water collecting cup 35 flips over, since the lower end of the water collecting cup 35 moves up along the arc, the water collecting cup 35 can push the one-way rotating ring 39 to rotate a unit angle in the specified direction through the ball head connecting rod 40. When the water collecting cup 35 finishes flipping and the cup tension spring 37 is pulled back to the vertical state, since the one-way rotating ring 39 cannot rotate in the opposite direction, under the action of the interaction force, the one-way rotating ring 39 will pull the water collecting cup 35 and the mounting frame 33 to rotate a unit angle in the specified direction through the ball head connecting rod 40, so that the mounting frame 33 and the water collecting cup 35 can be in a stable state. Since the water collecting cup 35 rotates along the circumference of the column 32, when the water collecting cup 35 flips over next time, the landing point of the condensed water poured out of the water collecting cup 35 on the floating plate 38 will change, thereby changing the force direction of the floating plate 38, and then changing the swaying direction of the collecting bottle 31, the Y-tube mechanism 20 and the breathing connecting tube 10, so that the condensed water remaining in the breathing connecting tube 10 can be further discharged, so that the collecting bottle 31 can collect the condensed water more fully.

[0055] See also Figure 1 , Figure 2 , Figure 3 and Figure 4In some embodiments, the locking assembly 23 includes a latch 231 and a plurality of positioning holes 232. The positioning holes 232 are formed on the outer surface of the mounting ring shell 211, and the plurality of positioning holes 232 are evenly spaced and arranged around the outer circumference of the connecting tube 212. The latch 231 is movably disposed in the rotating outer sleeve 221, and the latch 231 is used to selectively insert into any one of the positioning holes 232, so that the relative position of the rotating outer sleeve 221 and the mounting ring shell 211 remains fixed.

[0056] Through the above arrangement, when the latch 231 is completely pulled out of the positioning hole 232, the locking assembly 23 is in an open state, and the rotating assembly 22 can rotate relative to the mounting ring shell 211. When the latch 231 is inserted into any one of the positioning holes 232, the locking assembly 23 is in a locked state, and the rotating assembly 22 cannot rotate relative to the mounting ring shell 211. Since a plurality of positioning holes 232 are evenly spaced and arranged around the outer circumference of the connecting tube 212, it can be ensured that when the collecting mechanism 30 moves to the lowest position under the action of gravity, at least one positioning hole 232 is aligned with the latch 231, so that the latch 231 can be inserted into the positioning hole 232 to lock and fix the position of the collecting mechanism 30 relative to the mounting ring shell 211. In addition, the above-mentioned use and operation of the locking assembly 23 is very simple, which can facilitate the operation of the operator.

[0057] The technical features of the above embodiments may be combined arbitrarily. To make the description concise, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0058] The above-described embodiments only express several implementation methods of the present invention, and the description thereof is relatively specific and detailed, but it cannot be understood as limiting the scope of the present invention. It should be pointed out that, for a person of ordinary skill in the art, several modifications and improvements can be made without departing from the concept of the present invention, and these all belong to the protection scope of the present invention. Therefore, the protection scope of the present invention shall be subject to the attached claims.
