Description

Technical Field

[0001] The present invention relates to the technical field of medical devices, and in particular to a ventilator pipeline with a condensed water collection function. Background Art

[0002] Ventilators are very common medical devices. When a patient is seriously ill and unable to breathe on their own, they are used to assist or force the patient to breathe. During operation, condensation forms in the ventilator's tubing. This accumulation of condensation can affect the stability of gas flow and pressure within the tubing and can also easily breed bacteria. Therefore, a condensation collection device is required to collect the condensation in the ventilator tubing.

[0003] Current condensate collection devices are manually installed on ventilator tubing, and must be located at the lowest point in the tubing so that condensed water in the tubing can flow automatically into the device under the influence of gravity. However, since manual installation cannot ensure that the condensate collection device is at the lowest point in the tubing, the device's effectiveness in collecting condensed water in the tubing is reduced, creating an urgent need to address this issue.

[0038] See also Figures 1 to 6 The embodiment of the present invention provides a ventilator circuit 100 with a condensed water collection function, which is applied to a ventilator. The ventilator circuit includes a collection mechanism 30, a Y-shaped tube mechanism 20, and two respiratory connecting tubes 10.

[0039] The breathing connection tube 10 is a corrugated hose. During operation, condensed water will form within the breathing connection tube 10. A Y-shaped tube mechanism 20 is connected between the two breathing connection tubes 10 and the collection mechanism 30. This connects the two breathing connection tubes 10 with the collection mechanism 30, allowing the condensed water within the breathing connection tubes 10 to flow through the Y-shaped tube mechanism 20 into the collection mechanism 30. The collection mechanism 30 is used to collect and store the condensed water within the breathing connection tubes 10.

[0040] The Y-shaped tube mechanism 20 includes a connecting member 21 , a rotating assembly 22 and a locking assembly 23 .

[0041] The connector 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 tubes 212 are 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.

[0042] The rotating assembly 22 is connected to the mounting ring housing 211 and can rotate on the mounting ring housing 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 .

[0043] The locking assembly 23 is disposed between the rotating assembly 22 and the mounting ring housing 211. The locking assembly 23 has an open state and a locked state. When the locking assembly 23 is in the open state, the collection mechanism 30 can rotate on the mounting ring housing 211 along with the rotating assembly 22 about the central axis O. When the locking assembly 23 is in the locked state, the rotating assembly 22 cannot rotate, thereby fixing the relative position of the collection mechanism 30 and the mounting ring housing 211.

[0044] When the above-mentioned ventilator circuit 100 with a condensed water collection function is in use, one of the breathing connecting tubes 10 is used to connect to the ventilator, and the other breathing connecting 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 connecting tube 10 through the rotating assembly 22 under the action of its own gravity. 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 connecting tube 10 at this time, the condensed water generated in the breathing connecting 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 connecting 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, which 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.

[0045] See also Figure 2 and Figure 6In some embodiments, the end of the connecting tube 212 away from the mounting ring housing 211 curves and extends away from the collection mechanism 30. This arrangement allows the end of the breathing connecting tube 10 connected to the connecting tube 212 to be lower than the end of the breathing connecting tube 10 away from the connecting tube 212, thereby facilitating the flow of condensed water within the breathing connecting tube 10 into the connecting tube 212 and the inner cavity 213 under the action of gravity.

[0046] 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 mounted on the outer circumference of the mounting ring housing 211, and the connecting tube 212 is inserted through the rotating outer sleeve 221. The inner sidewall of the mounting ring housing 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 housing 211 is provided with a clearance opening 215 that communicates with the inner cavity 213. The clearance opening 215 extends along the circumference of the mounting ring housing 211. The rotating inner ring 222 is provided with an inner connecting tube 224 that communicates with the inner cavity 213. The inner connecting tube 224 is generally cylindrical and extends through the clearance opening 215 to the outside of the inner cavity 213. The rotating outer sleeve 221 is provided with an outer connecting tube 223, which is generally cylindrical in shape. The inner connecting tube 224 is inserted into the outer connecting tube 223 and abuts against the inner sidewall of the outer connecting tube 223. Due to this arrangement, since the outer connecting tube 223 is sleeved around the inner connecting tube 224 and the two abut against each other, the rotating outer sleeve 221 can rotate synchronously with the rotating inner ring 222 about the central axis O of the mounting ring housing 211. During this rotation, the inner connecting tube 224 moves within the clearance opening 215 along the extension direction of the clearance opening 215. The rotation range of the inner connecting tube 224 is limited by the extension length of the clearance opening 215.

[0047] The collection mechanism 30 includes a collection bottle 31, which comprises a body 311 and a connecting sleeve 312 connected to the body 311. The body 311 is generally cylindrical, and the connecting sleeve 312 is also generally cylindrical. The top of the body 311 gradually narrows and connects to one end of the connecting sleeve 312. The body 311 defines a collection chamber 313, which is communicated with the connecting sleeve 312. The connecting sleeve 312 is threadedly attached to the outer circumference of the outer connecting tube 223, connecting the collection chamber 313 with the inner chamber 213. The collection bottle 31 can be made of a transparent or translucent material to facilitate operator observation of the level of collected condensate within the collection bottle 31.

[0048] Through the above-mentioned 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 ring 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 at 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.

[0049] See also Figure 1 、 Figure 5 and Figure 9 In some embodiments, the rotating inner ring 222 is further provided with a branch hose 43 that is connected to 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, thereby preventing the condensed water in the inner cavity 213 from spraying out of the branch hose 43 when the end cover 45 is opened. The end cover 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 cover 45 can be opened and closed, and when the end cover 45 is closed, it can prevent external 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 the negative pressure suction device (not shown in the figure), and then the valve 44 can be opened. The condensed water in the inner cavity 213 can be sucked out through the branch hose 43 using the negative pressure suction device.

[0050] See also Figure 11 and Figure 12In some embodiments, the respiratory connection tube 10 is provided with a branch hose 43 connected thereto. The branch hose 43 is provided with a valve 44 and an end cap 45. The valve 44 is used to control the opening and closing of the branch hose 43, thereby preventing condensed water in the respiratory connection tube 10 from being ejected from the branch hose 43 when the end cap 45 is opened. The end cap 45 is mounted on the end of the branch hose 43 away from the rotating inner ring 222 and seals the end of the branch hose 43. The end cap 45 can be opened and closed, and when closed, it prevents foreign matter from entering the branch hose 43. At least a portion of the end cap 45 is connected to the branch hose 43 so that it does not separate from the branch hose 43 when opened, thereby preventing the end cap 45 from being accidentally lost. With this arrangement, when the end cap 45 is opened, the branch hose 43 can be connected to a negative pressure aspirator (not shown). Then, the valve 44 is opened, and the negative pressure aspirator can be used to suction and drain the condensed water in the respiratory connection tube 10 through the branch hose 43.

[0051] It should be noted that, in some embodiments, the ventilator circuit 100 with a condensed water collection function may be provided with both a collection mechanism 30 and a branch hose 43. The collection mechanism 30 can be used to collect condensed water within the respiratory connecting tube 10, and the branch hose 43 can be used in conjunction with a negative pressure suction device to further collect condensed water within the respiratory connecting tube 10. In other embodiments, the ventilator circuit 100 with a condensed water collection function may be provided with only the collection mechanism 30 or only the branch hose 43. Both the collection mechanism 30 and the branch hose 43 can be provided separately to collect condensed water within the respiratory connecting tube 10.

[0052] 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 collection cavity 313. A first blocking member 227 is inserted into 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-shaped 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 larger 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 the first connecting rod 2272 is connected to the first blocking 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.

[0053] The collection mechanism 30 also includes a column 32 and a mounting bracket 33. The column 32 is vertically positioned at the center of the inner bottom surface of the bottle body 311, and the mounting bracket 33 is positioned at the top of the column 32. A first push rod 34 is vertically mounted on the mounting bracket 33. The first push rod 34 is positioned opposite the first connecting rod 2272 and has a diameter smaller than the diameter of the water outlet 226.

[0054] When the collection bottle 31 is separated from the external connection tube 223, the first plugging head 2271 engages 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 through the water outlet 226. When the collection bottle 31 is connected to the external connection tube 223, the first push rod 34 vertically pushes the first connecting rod 2272 upward to separate the first plugging head 2271 from the water outlet 226. At this time, the condensed water in the inner cavity 213 can flow into the collection bottle 31 through the water outlet 226.

[0055] Through the above-mentioned 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 pathogens cannot enter the inner cavity 213 from the water outlet 226, thereby ensuring the sanitary environment inside the breathing connecting tube 10.

[0056] In some embodiments, the mounting bracket 33 includes a sleeve 331 and a mounting post 332. The sleeve 331 is a cylindrical structure with one end open, and the sleeve 331 is sleeved on the top of the post 32. The mounting post 332 is a roughly cylindrical structure, and is connected to the side of the sleeve 331 facing away from the post 32. The diameter of the mounting post 332 is smaller than the diameter of the sleeve 331. A blocking plate 333 is movably mounted on the mounting post 332. The blocking plate 333 is a roughly circular plate-shaped structure, and 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 post 332. A second push rod 2241 is provided at the end of the inner connecting tube 224 away from the rotating inner ring 222, and the vertical projection of the second push rod 2241 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 along the circumference of the inner connecting tube 224 .

[0057] When the collection bottle 31 is separated from the external connection tube 223, the support spring 334 holds the blocking plate 333 against the inner sidewall of the bottle body 311, separating the upper and lower sides of the blocking plate 333. When the collection 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, separating the blocking plate 333 from the inner sidewall of the bottle body 311. At this time, the support spring 334 is in a compressed state, and condensed water flowing out of the inner cavity 213 can flow into the interior of the bottle body 311 through the gap between the blocking plate 333 and the inner sidewall of the bottle body 311.

[0058] 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 smoothly collect the condensed water. 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 support spring 334 until the sealing plate 333 is in contact with 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, which can avoid the condensed water in the collecting bottle 31 from accidentally spilling during the replacement of the collecting bottle 31, which is safer and more hygienic.

[0059] See also Figure 6 、 Figure 7 、 Figure 9 and Figure 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 collection 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.

[0060] The mounting frame 33 also includes a connecting bracket 335, a connecting shaft 336, and a diverter pipe 337 connected to the water receiving chamber 3321. The connecting bracket 335 is mounted on the outer wall of the sleeve 331. The connecting block 36 is rotatably connected to the connecting bracket 335 via the connecting shaft 336, thereby achieving a rotational 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. The tension spring 37 has one end, facing away from the water collecting cup 35, fixedly connected to the outer wall of the sleeve 331. The diverter pipe 337 has one end connected to the sleeve 331 and the other end extending above the water collecting cup 35. The diverter pipe 337 is used to drain condensed water from the water receiving chamber 3321 into the water collecting cup 35.

[0061] If the condensed water in the water collection cup 35 has not reached a specified level, the tension spring 37 pulls the water collection cup 35 to maintain its upright position. When the condensed water in the water collection cup 35 reaches the specified level, the torque generated by the water collection cup 35 and the condensed water therein overcomes the torque of the tension spring 37, causing the water collection cup 35 to flip about the connecting shaft 336, thereby pouring the condensed water in the water collection cup 35 onto the floating plate 38. It should be noted that the "specified level" above refers to the minimum level of condensed water in the water collection cup 35 required for the water collection cup 35 and the condensed water therein to overcome the torque of the tension spring 37 and cause the water collection cup 35 to flip. When the condensed water in the water collection cup 35 reaches the specified level, the torque generated by the water collection cup 35 and the condensed water therein overcomes the torque of the tension spring 37, causing the water collection cup 35 to flip about the connecting shaft 336, thereby pouring the condensed water in the water collection 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, the water collecting cup 35 remains in a vertical state under the tension of the tension spring 37 .

[0062] With the above arrangement, during normal use, condensed water flows out of the water outlet 226 and falls into the water receiving chamber 3321. It then flows through the diverter pipe 337 into the water collection cup 35. In the initial stage of water collection, the tension of the tension spring 37 maintains the water collection cup 35 in an upright position. As the condensed water in the water collection cup 35 gradually increases and reaches a predetermined level, the torque generated by the water collection cup 35 and the condensed water therein overcomes the torque of the tension spring 37. At this point, the water collection cup 35 can tilt about the connecting shaft 336, thereby pouring the condensed water out of the water collection cup 35 onto the floating plate 38. After the condensed water is poured out, the water collection cup 35 is pulled back to its upright position by the tension spring 37 to continue collecting condensed water. When condensed water poured out of the water collection cup 35 falls onto the surface of the floating plate 38, it generates an impact force on the floating plate 38. This impact force acts on the upright post 32, causing the collection bottle 31 to swing and oscillate. This swing and oscillation of the collection bottle 31 drives the Y-tube mechanism 20 and the breathing connecting tube 10 to swing and oscillate, thereby further draining the condensed water remaining in the folds of the breathing connecting tube 10 into the inner cavity 213, thereby further collecting the condensed water in the breathing connecting tube 10. The condensed water that falls onto the floating plate 38 can flow from the gap between the floating plate 38 and the inner sidewall of the bottle body 311 to the bottom of the floating plate 38. As the amount of condensed water below the floating plate 38 gradually increases, the condensed water below the floating plate 38 pushes the floating plate 38 vertically upward along the upright post 32, ensuring that the floating plate 38 always floats on the surface of the condensed water to receive the condensed water poured out of the collection cup.

[0063] In some embodiments, the floating plate 38 includes a connecting plate 381 and a floating ring 382. The connecting plate 381 is a generally circular plate-shaped structure made of a hard plate, such as hard plastic, and is used to collect condensed water from the water collection cup 35. The connecting plate 381 is movably mounted on the column 32. The floating ring 382 is a generally annular structure, such as a rubber ring, and is mounted around the outer circumference of the connecting plate 381. The outer wall of the floating ring 382 is spaced apart from the inner wall of the bottle body 311. The density of the connecting plate 381 is less than that of water, while the density of the floating ring 382 is less than that of the connecting plate 381.

[0064] With this arrangement, condensed water pouring out of the water collection cup 35 lands on the rigid connecting plate 381, increasing the impact force on the floating ring 382 and thereby increasing the yaw amplitude of the collection bottle 31, thereby draining any condensed water remaining in the folds of the breathing connection tube 10 out of the breathing connection tube 10 as much as possible. Condensed water that falls on the connecting plate 381 can flow through the gap between the floating ring 382 and the inner wall of the bottle body 311 and into the bottom of the floating plate 38. As the amount of condensed water below the floating plate 38 gradually increases, the density of the connecting plate 381 is lower than that of water, and the density of the floating ring 382 is lower than that of the connecting plate 381. As a result, the overall density of the floating plate 38 is lower than that of water. Buoyancy allows the floating plate 38 to remain on the surface of the condensed water in the bottle body 311, allowing it to continue to collect condensed water pouring out of the water collection cup 35. Furthermore, because the floating ring 382 has a lower density than the connecting plate 381, it enhances the stability and reliability of the floating plate 38's floating on the condensed water surface.

[0065] See also Figure 6 、 Figure 7 and Figure 8 In some embodiments, a water outlet 338 is provided at one end of the diverter pipe 337 away from the sleeve 331, and the axial direction of the water outlet 338 is vertical. A second blocking member 339 is inserted into the diverter 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 diverter pipe 337, and the maximum diameter of the second blocking head 3391 is larger 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 generally cylindrical structure. One end of the second connecting rod 3392 is connected to the second plugging head 3391, and the other end passes through the water outlet 338 and extends outside the diverter tube 337. The diameter of the second connecting rod 3392 is smaller than that of the water outlet 338, allowing the second connecting rod 3392 to move freely within the water outlet 338. A third push rod 351 is vertically mounted on the inner bottom wall of the water collection cup 35. The third push rod 351 is disposed opposite the second connecting rod 3392 and has a diameter smaller than that of the water outlet 338. A guide slope 3393 is provided on the end of the second connecting rod 3392 away from the second plugging head 3391. The guide slope 3393 is inclined relative to the end of the second connecting rod 3392 away from the second plugging head 3391, toward the second plugging head 3391.

[0066] When the water collection cup 35 is in the flipped state, the third push rod 351 is separated from the second connecting rod 3392, and the second sealing head 3391 is in contact with the water outlet 338 to block the water outlet 338. At this time, the condensed water in the diverter tube 337 cannot flow out of the water outlet 338. When the water collection cup 35 transitions 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 sealing head 3391, so that the third push rod 351 lifts the second connecting rod 3392 upward, thereby separating the second sealing head 3391 from the water outlet 338. At this time, the condensed water in the diverter tube 337 can flow out of the water outlet 338 into the water collection cup 35.

[0067] With the above arrangement, when the condensed water in the water collection cup 35 has not reached the specified liquid level, the water collection cup 35 is in a vertical position. At this time, the third push rod 351 lifts the second connecting rod 3392 upward, separating the second plugging head 3391 from the water outlet 338, and the condensed water in the diverter tube 337 flows out of the water outlet 338 into the water collection cup 35. As the condensed water in the water collection cup 35 increases, when the condensed water in the water collection cup 35 reaches the specified liquid level, the water collection cup 35 flips over. At this 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 abuts against and blocks the water outlet 338. At this time, the condensed water in the diverter tube 337 cannot flow out of 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 from the flipped state to the vertical state. During the above process, the end of the third push rod 351 will first contact the guiding inclined surface 3393, and will move along the guiding inclined surface 3393 toward the end face of the second connecting rod 3392 away from the second plugging head 3391. During 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 again, 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 (as shown in FIG. Figure 8 In the state shown), the third push rod 351 stably supports the second blocking member 339 so that the second blocking head 3391 is completely separated from the water outlet 338, and the water outlet 338 is opened again, so that the water collecting cup 35 can continue to collect the condensed water flowing out of the water outlet 338.

[0068] In some embodiments, the sleeve 331 is rotatably mounted on the top of the column 32. A one-way rotating ring 39 is also mounted on the column 32. The one-way rotating ring 39 is connected to the column 32 via a ratchet mechanism (not shown) so that the one-way rotating ring 39 can only rotate relative to the column 32 in a specified direction. The "specified direction" mentioned above depends on the specific installation direction of the ratchet wheel of the ratchet mechanism.

[0069] A first mounting block 391 is provided on the outer wall of the one-way rotating ring 39, and a second mounting block 352 is provided at the bottom end of the outer wall of the water collection cup 35. A ball-jointed connecting rod 40 is disposed between the first and second mounting blocks 391, 352. A first connecting ball 41 and a second connecting ball 42 are provided at opposite ends of the ball-jointed connecting rod 40, respectively. At least a portion of the first connecting ball 41 is embedded within the first mounting block 391 and is rotatable relative to the first mounting block 391. At least a portion of the second connecting ball 42 is embedded within the second mounting block 352 and is rotatable relative to the second mounting block 352.

[0070] When the water collection cup 35 is in the flipped state, the water collection cup 35 drives the one-way rotating ring 39 to rotate a unit angle in the specified direction via the ball-jointed connecting rod 40. The "unit angle" described above depends on the specific size of the ratchet wheel in the ratchet mechanism. It should be understood that each time the water collection cup 35 flips, the one-way rotating ring 39 rotates a unit angle in the specified direction.

[0071] 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, the next time the water collecting cup 35 flips over, 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 yaw and shaking 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.

[0072] 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 211 and are evenly spaced around the outer circumference of the connecting tube 212. The latch 231 is movably disposed through the rotating outer sleeve 221 and can be selectively inserted into any of the positioning holes 232 to maintain a fixed relative position between the rotating outer sleeve 221 and the mounting ring 211.

[0073] With this arrangement, when the latch 231 is completely removed from the positioning hole 232, the locking assembly 23 is in the open position, allowing the rotating assembly 22 to rotate relative to the mounting ring 211. When the latch 231 is inserted into any of the positioning holes 232, the locking assembly 23 is in the locked position, preventing the rotating assembly 22 from rotating relative to the mounting ring 211. Because the positioning holes 232 are evenly spaced around the outer circumference of the connecting tube 212, when the collection mechanism 30 moves to its lowest position under the action of gravity, at least one positioning hole 232 aligns with the latch 231, allowing the latch 231 to be inserted into the positioning hole 232, thereby locking the collection mechanism 30 in place relative to the mounting ring 211. Furthermore, the locking assembly 23 is very simple to use, making it convenient for the operator.

[0074] The technical features of the above embodiments can 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.

[0075] The above-described embodiments merely illustrate several embodiments of the present invention, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the present invention. It should be noted that a person skilled in the art would be able to make various modifications and improvements without departing from the spirit of the present invention, all of which fall within the scope of protection of the present invention.
