Description

Technical Field

[0001] This application relates to the field of valve component design, and more particularly to a multi-joint air inlet valve seat for an oxygen chamber. Background Technology

[0002] A soft oxygen chamber is a pressurized device made of flexible materials. It creates an oxygen-rich environment with a pressure slightly higher than the outside air by filling the chamber with fresh, clean air or an oxygen-enriched mixture. The human body inhales oxygen into the lungs, which then diffuses into the blood through the alveoli and capillaries. The oxygen is then transported to various parts of the body through blood circulation. This increases the dissolved oxygen in the blood and tissues, improves oxygen permeability, maintains the body's vital functions, improves the condition, or corrects hypoxia symptoms, thereby achieving health care, rehabilitation, and treatment functions.

[0003] During the use of a flexible oxygen chamber, an intake pipe is needed to deliver oxygen or oxygen-enriched air into the chamber to control the oxygen concentration. An exhaust pipe is needed to expel waste gas or excess oxygen to maintain stable pressure within the chamber. Furthermore, for some high-quality flexible oxygen chambers, a pressure monitoring pipe can be connected to the outside. This pipe connects to external pressure monitoring equipment, enabling real-time monitoring of pressure changes within the chamber.

[0004] An air inlet valve seat needs to be added at the connection between the trachea and the flexible oxygen chamber. The air inlet valve seat has an air inlet connector for the air supply pipe. As the connecting carrier for the trachea, the air inlet valve seat allows for smooth communication between the trachea and the interior space of the flexible oxygen chamber. Because there are many types of trachea connected to the outside of the flexible oxygen chamber, each trachea is connected to the chamber by an air inlet valve seat. This requires pre-drilling a corresponding number of holes in the chamber fabric for installing the air inlet valve seats, resulting in complex installation operations. Furthermore, the connection point between the air inlet valve seat and the chamber body is prone to gas leakage, which is detrimental to maintaining a good seal inside the flexible oxygen chamber and needs improvement. Utility Model Content

[0005] Based on this, this application provides a multi-connector air inlet valve seat for oxygen chambers, which can improve the convenience of connecting various air pipes to the oxygen chamber fabric and ensure that the interior of the soft oxygen chamber maintains a good sealing effect.

[0006] The multi-connector air inlet valve seat for an oxygen chamber provided in this application adopts the following technical solution:

[0007] A multi-connector air inlet valve seat for an oxygen chamber includes a valve seat body and a locking element. The valve seat body includes a main valve seat and a valve cover disposed on the outer periphery of the main valve seat. The main valve seat has multiple axially penetrating connecting holes, and an air inlet connector is detachably connected to the connecting holes. The locking element is threadedly connected to the main valve seat. In the fixed state, the valve cover and the locking element are disposed on two opposite sides of the oxygen chamber fabric and together clamp the oxygen chamber fabric.

[0008] Optionally, the side end face of the main valve seat is provided with an integrally formed plug-in portion, and the locking element is threadedly connected to the plug-in portion; the side edge of the main valve seat near the plug-in portion is provided with an annular groove, and the inner peripheral wall of the valve cover is provided with an extension portion. The extension portion is located on one side edge of the valve cover. In the fixed state, the extension portion is matched and located in the annular groove, and the valve cover and the main valve seat are circumferentially linked.

[0009] Optionally, the inner circumferential surfaces of the extension together form a regular polygon shape, and the annular groove is adapted to the shape of the extension.

[0010] Optionally, a linkage structure is provided between the valve cover and the main valve seat. The linkage structure includes a limiting protrusion and a limiting groove that is adapted to be inserted into it. The limiting protrusion and the limiting groove are respectively disposed between the extension and the annular groove.

[0011] Optionally, the main valve seat is provided with multiple mounting ports, each of which is equipped with a mounting base, and the connection hole is located in the mounting base; the mounting base can be detachably fixed to the mounting port through a quick-release structure.

[0012] Optionally, the quick-release structure includes a guide post fixed to the outer wall of the mounting base and a guide groove formed in the inner peripheral wall of the mounting opening. The guide groove includes a straight section and a curved section connected thereto. The straight section extends in the same direction as the opening direction of the mounting opening, and the curved section extends along the radial direction of the mounting opening. A return spring is provided on the bottom wall of the mounting opening. In the fixed state, the return spring normally forces the mounting base to move outward, at which time the guide post stops at the end of the curved section away from the straight section.

[0013] Optionally, a sealing felt ring may be fitted onto the outer circumferential surface of the mounting base.

[0014] Optionally, the multi-connector intake valve seat also includes a silicone gasket disposed between the valve seat body and the locking element. Two silicone gaskets are provided, and the two silicone gaskets are respectively disposed on two opposite sides of the oxygen chamber fabric.

[0015] In summary, this application includes at least one of the following beneficial technical effects:

[0016] 1. After the valve seat body is inserted into the oxygen chamber tarpaulin via the main valve seat, the locking element is threaded onto the main valve seat. The locking element and the valve cover can jointly clamp the oxygen chamber tarpaulin, quickly completing the installation of the inlet valve seat. This application integrates multiple connection holes onto the same valve seat body. Connection holes with different inner diameters can be used to connect different types of gas pipes, thereby improving the connection convenience between various gas pipes and the oxygen chamber tarpaulin. Furthermore, since the number of valve seat bodies is reduced, the number of pre-drilled holes required on the oxygen chamber tarpaulin is reduced, which helps to reduce the possibility of gas leakage at the connection point between the inlet valve seat and the soft oxygen chamber, ensuring a good sealing effect inside the soft oxygen chamber.

[0017] 2. Different soft oxygen chambers have different requirements for various types of air tubes. By making the main valve seat and valve cover separate, the main valve seat with the corresponding number and size of connection holes can be selected according to actual needs to suit soft oxygen chambers with different requirements. After selecting the corresponding main valve seat, the locking part is threaded to the main valve seat, and the extension of the valve cover can be located inside the annular groove of the main valve seat to play the role of positioning the valve cover. Through the circumferential linkage between the valve cover and the main valve seat, rotating the valve cover can smoothly drive the main valve seat to rotate, thereby forcing the locking part and the main valve seat to come closer to each other to jointly clamp the oxygen chamber fabric.

[0018] 3. Since different types of air tubes have different outer diameters, this application sets up a quick-release structure to achieve quick assembly and disassembly between the mounting base and the mounting port. This allows for convenient and quick replacement of mounting bases with connection holes of different inner diameters. Consequently, it enables the selection of the corresponding air inlet connector and connection of the corresponding type of air tube according to actual needs, offering the advantage of free combination and making operation more convenient.

[0019] 4. When the guide post of the mounting base enters the guide groove, it first moves axially along the straight section and enters the inner side of the mounting opening. After the mounting base moves to the bottom of the straight section, it is forced to rotate, and the guide post can gradually enter the curved section. Under the elastic force of the return spring, the mounting base can stay at the end of the curved section away from the straight section, so as to realize the quick disassembly and replacement of the mounting base.

[0020] 5. When the locking element and the valve cover clamp the oxygen chamber fabric together, the two silicone gaskets can abut against the two opposite sides of the oxygen chamber fabric, thereby improving the sealing effect between the air intake valve seat and the oxygen chamber fabric and reducing the possibility of air leakage inside the soft oxygen chamber.

[0027] The following is in conjunction with the appendix Figure 1-5 This application will be described in further detail.

[0028] Example 1:

[0029] This application discloses a multi-connector air inlet valve seat for an oxygen chamber.

[0030] Reference Figure 1 A multi-connector air intake valve seat for an oxygen chamber includes a valve seat body, a locking element 3, and a silicone gasket 4; wherein the valve seat body includes a main valve seat 1 and a valve cover 2, which are separately arranged.

[0031] Reference Figure 2 One end face of the main valve seat 1 is provided with a plug-in portion 12, which is coaxially arranged with the main valve seat 1 and integrally formed. The outer peripheral surface of the plug-in portion 12 is provided with an external thread, and the outer ring of the locking member 3 is provided with an internal thread. The locking member 3 can be threadedly connected to the plug-in portion 12 through the cooperation of the internal thread and the external thread. In the fixed state, that is, when the intake valve seat is fixedly installed on the soft oxygen chamber fabric, the plug-in portion 12 can pass through the preset hole on the soft oxygen chamber fabric. At this time, the locking member 3 and the main valve seat 1 can be located on two opposite sides of the oxygen chamber fabric.

[0032] The outer diameter of the main valve seat 1 is larger than that of the insertion part 12. An annular groove 11 is provided on the outer circumferential surface of the main valve seat 1, located on one side edge of the main valve seat 1 near the insertion part 12. The valve cover 2 has an inner cavity through which the main valve seat 1 passes, and an extension 21 is provided on the inner circumferential wall of the valve cover 2. The extension 21 is located on one side edge of the valve cover 2 and is integrally formed with the valve cover 2. In the fixed state, by allowing the insertion part 12 to pass sequentially through the inner cavity of the valve cover 2 and the pre-set holes on the oxygen chamber fabric, the main valve seat 1 can enter the inner cavity of the valve cover 2. The side wall of the annular groove 11 on the main valve seat 1 can abut against the extension 21, thereby preventing the valve cover 2 from detaching from the main valve seat 1.

[0033] Furthermore, the main valve seat 1 and the valve cover 2 are circumferentially linked. Specifically, in this embodiment, the inner circumferential surfaces of the extension 21 are enclosed to form a regular polygon, and each inner wall of the annular groove 11 is also formed into a polygon shape that matches the shape of the extension 21. Based on this, when the main valve seat 1 enters the inner cavity of the valve cover 2, each inner wall of the annular groove 11 can match and abut against each side of the extension 21, thereby realizing the circumferential linkage between the main valve seat 1 and the valve cover 2. When the valve cover 2 rotates, it can drive the main valve seat 1 to rotate synchronously.

[0034] The outer circumferential surface of the valve cover 2 is provided with a structural notch 22. The structural notch 22 is provided so that a wrench can enter the outside of the valve cover 2 and turn the valve cover 2 to rotate, thereby driving the main valve seat 1 to rotate. It can be understood that in the actual installation process, by using a wrench to turn the valve cover 2 and the locking member 3 respectively, forcing the valve cover 2 and the locking member 3 to move towards each other, the intake valve seat can be firmly fixed to the oxygen chamber fabric.

[0035] There are two silicone gaskets 4, both of which are located between the main valve seat 1 and the locking member 3. In the fixed state, the two silicone gaskets 4 can press against the two opposite sides of the oxygen chamber fabric, thereby achieving a good sealing effect and reducing the possibility of oxygen-enriched air inside the soft oxygen chamber leaking into the external environment.

[0036] The main valve seat 1 is provided with multiple connection holes 13, each of which axially extends from the main valve seat 1 to the insertion part 12. The inner wall of the connection hole 13 is provided with threads, and each connection hole 13 is detachably connected to an air inlet connector 14 via a threaded connection. Since the types and quantities of air pipes required to be connected to different specifications of soft oxygen chambers vary, the inner diameter of the connection hole 13 and the model of the air inlet connector 14 can be selectively set according to actual needs. Based on this, the installation of the air inlet valve seat and the connection of various air pipes can be completed quickly, thereby improving the convenience of connecting various air pipes to the oxygen chamber fabric.

[0037] Based on this, this application integrates multiple connection holes 13 onto the same valve seat body. Connection holes 13 with different inner diameters can be used to connect different types of air pipes, thereby improving the convenience of connecting various air pipes with the oxygen chamber fabric. Furthermore, since the number of valve seat bodies is reduced, the number of pre-set holes required on the oxygen chamber fabric is reduced, which helps to reduce the possibility of gas leakage at the connection between the air intake valve seat and the soft oxygen chamber, and maintains a good sealing effect inside the soft oxygen chamber.

[0038] Example 2:

[0039] This application discloses a multi-connector air inlet valve seat for an oxygen chamber.

[0040] Reference Figure 3The present application discloses a multi-connector air inlet valve seat for an oxygen chamber. The other components are the same as those in embodiment 1, and will not be described in detail here. The difference from embodiment 1 is that in this embodiment, the valve cover 2 and the main valve seat 1 are circumferentially linked through a linkage structure 5.

[0041] Specifically, the linkage structure 5 includes a limiting protrusion 51 and a limiting groove 52, which are plugged into each other. In this embodiment, the limiting groove 52 is provided on the side wall of the annular groove 11, and there are multiple limiting grooves 52. All limiting grooves 52 are equidistantly arranged around the central axis of the main valve seat 1. The limiting protrusion 51 is integrally formed on the side end face of the extension 21. In the fixed state, when the side wall of the annular groove 11 on the main valve seat 1 matches and abuts against the extension 21, the limiting protrusion 51 can enter the interior of a certain limiting groove 52, so that when the valve cover 2 rotates, it can drive the main valve seat 1 to rotate together. Then, by rotating the valve cover 2, the intake valve seat can be firmly fixed on the oxygen chamber fabric.

[0042] It should be noted that, in another feasible embodiment, the limiting groove 52 may be disposed on the side end face of the extension 21, and the limiting protrusion 51 may also be disposed on the side end wall of the annular groove 11, not limited to the manner provided in this embodiment.

[0043] Example 3:

[0044] This application discloses a multi-connector air inlet valve seat for an oxygen chamber.

[0045] Reference Figure 4 This application discloses a multi-connector air inlet valve seat for an oxygen chamber. The remaining components are the same as in Embodiment 1, and will not be described in detail here. The difference from Embodiment 1 is that the main valve seat 1 in this application has multiple mounting ports 15, each with a mounting base 16. The mounting base 16 is detachably fixed to the mounting port 15 via a quick-release structure 6. A connection hole 13 is provided on the mounting base 16. By changing different mounting bases 16 to alter the diameter of the connection hole 13, the type of air inlet connector 14 connected to the air inlet valve seat can be adjusted, thereby correspondingly switching the type of connected air pipe. This offers the advantage of free combination, eliminating the need for custom-made air inlet valve seats for specific scenarios, making the use of the air inlet valve seat more convenient.

[0046] Simultaneously refer to Figure 5The quick-release structure 6 includes a guide post 61 and a guide groove 62. The guide post 61 is fixed to the outer wall of the mounting base 16, while the guide groove 62 is formed in the inner peripheral wall of the mounting opening 15. The guide groove 62 includes a straight segment 621 and a curved segment 622. The straight segment 621 extends in the same direction as the mounting opening 15, and its top end extends to the side of the main valve seat 1 away from the insertion part 12. The end of the curved segment 622 is connected to the bottom end of the straight segment 621, and the curved segment 622 extends along the radial direction of the mounting opening 15. The curved segment 622 has an arc shape when unfolded in a plane.

[0047] Additionally, returning Figure 4 A return spring 63 is installed on the bottom wall of the mounting hole. When the mounting base 16 is fitted into the mounting opening 15 and the guide post 61 enters the bottom end of the straight section 621, the return spring 63 is compressed. By forcing the mounting base 16 to rotate circumferentially by a certain angle, the guide post 61, after entering the curved section 622, can remain at the end of the curved section 622 away from the straight section 621 under the elastic force of the return spring 63, thereby making the mounting base 16 stable in the mounting opening 15. In addition, a sealing felt ring 17 is fitted on the outer circumferential surface of the mounting base 16. The sealing felt ring 17 can improve the sealing effect between the mounting base 16 and the mounting opening 15 and reduce the possibility of air leakage inside the soft oxygen chamber.

[0048] The above are preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made to the structure, shape and principle of this application should be covered within the scope of protection of this application.
