[0039] The condensate drainage device for a ventilator of the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments of the present invention.

[0040] It should be noted that, in the absence of conflict, the embodiments and features in the embodiments of the present application can be combined with each other. The present invention will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0041] It should be noted that the terms used herein are only for describing specific embodiments and are not intended to limit the exemplary embodiments according to the present application.

In addition, it should be understood that when the terms "comprise" and / or "include" are used in this specification, it indicates the presence of features, steps, operations, devices, components and / or combinations thereof.

[0042] It should be noted that the terms "first", "second", etc. in the specification and claims of the present application and the above-mentioned drawings are used to distinguish similar objects, and are not necessarily used to describe a specific order or sequence. It should be understood that the data used in this way can be interchangeable where appropriate, so that the embodiments of the present application described herein can be implemented in an order other than those illustrated or described herein, for example. In addition, the terms "including" and "having" and any of their variations are intended to cover non-exclusive inclusions, for example, a process, method, system, product or device that includes a series of steps or units is not necessarily limited to those steps or units that are clearly listed, but may include other steps or units that are not clearly listed or inherent to these processes, methods, products or devices.

[0043] For ease of description, spatially relative terms such as "above", "above", "on the upper surface of", "above", etc. may be used here to describe the spatial positional relationship between a device or feature and other devices or features as shown in the figure. It should be understood that spatially relative terms are intended to include different orientations of the device in use or operation in addition to the orientation described in the figure. For example, if the device in the accompanying drawings is inverted, the device described as "above other devices or structures" or "above other devices or structures" will be positioned as "below other devices or structures" or "below other devices or structures". Thus, the exemplary term "above" can include both "above" and "below". The device can also be positioned in other different ways (rotated 90 degrees or in other orientations), and the spatially relative descriptions used here are interpreted accordingly.

[0044] like Figure 1-Figure 3 As shown, the condensate drainage device for the ventilator comprises: an inlet pipe 1 connected to one end of the ventilator, an outlet pipe 2 connected to one end of the breathing mask, and a condensation chamber 3 for collecting condensate generated during breathing. The end of the inlet pipe 1 extends into the condensation chamber 3, the end of the outlet pipe 2 extends into the condensation chamber 3, and the inlet pipe 1 and the outlet pipe 2 extend into the condensation chamber 3 by a set distance respectively; the set distance is less than half of the long axis, but must extend out of the inner surface of the condensation chamber 3 to ensure that the condensate flowing on the inner wall of the condensation chamber 3 will not flow into the outlet pipe 2, and of course will not flow into the inlet pipe 1.

[0045] The condensed water generated by the air outlet pipe 2 can flow into the condensation chamber 3 from the air outlet pipe 2, and the condensed water will not flow back out from the air outlet pipe 2, thereby ensuring the collection of the condensed water and achieving backflow prevention.

[0046] Of course, in order to improve the collection capacity of condensed water, avoid excessive condensed water and reduce the anti-backflow effect, the drainage device also includes: a condensed water collection member 4, and the condensation chamber 3 is connected to the condensed water collection member 4. Therefore, the condensed water inside the condensation chamber 3 can flow into the condensed water collection member 4, improving the collection effect of condensed water, and by replacing the condensed water collection member 4, the continuous collection of condensed water can be met in time without affecting the continuous use of the ventilator.

[0047] In order to improve the condensation water collection capacity of the condensation chamber 3, especially to prevent the condensation water from backflowing during the primary collection of the condensation water, the condensation chamber 3 is a spherical cavity structure.

[0048] In order to facilitate the coordinated installation between the air inlet pipe 1 and the air outlet pipe 2, ensure that the air inlet pipe 1 and the air outlet pipe 2 are extended longer, reduce the possibility of backflow, and improve the water storage capacity of the condensation chamber 3. The condensation chamber 3 is an ellipsoidal cavity structure; the air inlet pipe 1 and the air outlet pipe 2 are respectively arranged on the long axis and the extension of the long axis of the ellipsoidal cavity structure. On the premise of leaving a gap between the air inlet pipe 1 and the air outlet pipe 2, the air outlet pipe 2 and the air inlet pipe 1 are extended to a greater extent, which can ensure that the condensed water of the air outlet pipe 2 will not flow back after entering the condensation chamber.

[0049] In order to ensure the ventilation effect and avoid the inlet pipe 1 from failing to smoothly flow oxygen into the outlet pipe 2, which would reduce the use effect of the ventilator, the inlet pipe 1 and the outlet pipe 2 are arranged relative to each other, which can ensure that oxygen flows smoothly from the inlet pipe 1 to the outlet pipe 2. In order to facilitate the discharge of condensed water from the outlet pipe 2 into the condensation chamber 3, the opposite ends of the inlet pipe 1 and the outlet pipe 2 are open.

[0050] In order to meet the installation requirements of the air inlet pipe 1 and the air outlet pipe 2, a certain cavity can be left on the outer wall between the air inlet pipe 1 and the air outlet pipe 2 to store condensed water. The minor axis length of the ellipsoidal cavity structure is greater than the diameter of the air inlet pipe 1 or the air outlet pipe 2. It is ensured that the inner wall of the condensation chamber 3 exceeds the outer wall of the air inlet pipe 1 and the air outlet pipe 2 by a certain size, and condensed water is collected in this area.

[0051] In order to further improve the collection effect of the condensation chamber 3, when the air inlet pipe 1 and the air outlet pipe are placed horizontally, the condensation water collecting member 4 is at the lowest position, and the condensation water collecting member 4 is connected to the minor axis extension line of the ellipsoidal cavity structure. When the air inlet pipe 1 and the air outlet pipe 2 are relatively not completely horizontal, the condensation water collecting member 4 is also at a lower position, which can meet the requirement that the condensation water flows smoothly into the condensation water collecting member 4.

[0052] In order to further ensure that the condensed water will not flow back into the condensation chamber 3 after entering the condensed water collecting part 4, the possibility of backflow is further reduced, and the condensed water collecting part 4 can be conveniently replaced in time to meet the further collection of condensed water. A guide tube 5 is integrally formed on the extension line of the short axis of the condensed water collecting part 4, and the end of the guide tube 5 extends into the condensed water collecting part 4. The guide tube 5 extends into the condensed water collecting part 4 for a certain distance, and the guide tube 5 does not touch the collected condensed water surface, so there will be no condensed water backflow, so the end of the guide tube 5 is suspended in the middle of the condensed water collecting part 4, higher than the collected condensed water surface. When the condensed water surface approaches the end of the guide tube 5, the condensed water collecting part can be replaced in time to avoid condensed water backflow.

[0053] In order to further reduce the possibility of backflow of the guide tube 5, especially the condensed water collecting member 4 is easily touched by the user and tipped over, to prevent the condensed water from flowing back along the guide tube 5, the end of the guide tube 5 is a round head structure, and a guide hole 51 is opened through the round head structure. The contact area with the collected condensed water and the space for backflow can be reduced, which can further ensure the use effect.

[0054] In order to ensure the collection effect of condensed water, ensure that the guide tube 5 is suspended in the air, and reduce the possibility that the end of the guide tube 5 touches the surface of the collected condensed water, the condensed water collector 4 includes: a collector body 41 for collecting condensed water and a support member 42 for supporting the guide tube 5, the outer wall of the support member 42 is fixedly connected to the collector body 41, and one side of the support member 42 extends into the collector body 41 to support the inner cavity of the collector body 41, and the guide tube 5 extends into the collector body 41 along the middle of the support member 42.

[0055] In order to achieve the supporting effect of the supporting member 42, the supporting member 42 includes: a supporting ball 421 that mainly serves the supporting function, a connecting tube 422 that serves the connecting function, and a connecting head 423 that connects the outer wall of the flow guide tube 5. The connecting tube 422 is integrally formed at one end of the supporting ball 421, and the connecting head 423 is integrally formed at the other end of the connecting tube 422. A conducting hole is provided through the supporting ball 421, the connecting tube 422, and the connecting head 423, and the flow guide tube 5 is arranged through the conducting hole; the end of the flow guide tube 5 extends a small distance from the supporting ball 421, thereby ensuring that the end of the flow guide tube 5 is at the center of the supporting ball 421, and the flow guide tube 5 is at a higher position regardless of how the collecting member body 41 rotates.

[0056] In order to facilitate the connection of the collecting body 41, a connecting buckle 52 is protruded from the outer wall of the guide tube 5, and the connecting head 423 extends into the connecting buckle 52 for connection;

[0057] In order to facilitate the buckle connection, avoid the downward pressure on the guide tube 5, and support the guide tube 5 to ensure that the condensed water flows smoothly from the condensation chamber 3 into the collector body 41. The connecting buckle 52 is an annular structure, and a connecting notch is provided on the inner wall of the lower side of the connecting buckle 52, and a rebate cavity is provided toward the middle of the connecting buckle 52 from the connecting notch; the outer wall of the connecting head 423 is a conical surface, and the conical surface extends into the connecting notch and the rebate cavity to cooperate with the buckle connection.

[0058] The above description is only a preferred embodiment of the present invention and is not intended to limit the protection scope of the present invention.
