Description

Technical Field

[0001] This utility model relates to ventilation therapy equipment, specifically to a pressure equalization control component for an oxygen concentrator. Furthermore, this utility model also relates to an oxygen concentrator equipped with this pressure equalization control component. Background Technology

[0002] With the improvement of living standards and the advancement of medical technology, people are paying more and more attention to health. This is especially true for those suffering from chronic respiratory diseases, such as chronic obstructive pulmonary disease (COPD) and asthma, for whom a continuous supply of oxygen is crucial. Portable oxygen concentrators, as a novel medical device, provide convenience for oxygen therapy in daily life. The core of a portable oxygen concentrator lies in the principle of pressure swing adsorption (PSA). Using ambient air as raw material, under normal temperature and low pressure conditions, it utilizes the characteristic that the adsorption capacity of molecular sieves increases when pressurized and decreases when depressurized, forming a rapid cycle of pressurized adsorption and depressurized desorption, thus separating oxygen and nitrogen from the air.

[0003] During the operation of an oxygen generator, air is delivered to an oxygen production unit, such as a molecular sieve adsorption tower, for oxygen-nitrogen separation. The resulting oxygen is delivered to the user, while the nitrogen is discharged into the external environment. For the commonly used dual-tower adsorption-desorption cycle oxygen production process, nitrogen removal needs to be completed quickly during the desorption and nitrogen removal steps to ensure stable oxygen supply. To address this, a pressure equalization control component can be connected to the oxygen outlets of the two adsorption towers. At specific times during each oxygen production cycle, the on / off state of the oxygen outlets of the two adsorption towers is switched, supplying the high-concentration oxygen produced at the end of the adsorption cycle in one tower to the other adsorption tower in the nitrogen removal cycle. This not only facilitates desorption of the sieve bed in the adsorption tower but also increases the initial oxygen concentration before entering the next adsorption cycle, ensuring a stable oxygen supply from the oxygen generator.

[0004] In traditional technologies, pressure equalization control components typically use hoses and connectors to connect relatively independent pressure equalization valves, check valves, and other components to meet the needs of pressure equalization and oxygen supply. However, this split structure is prone to leakage risks due to hose aging after prolonged use, and it also occupies limited space within the oxygen concentrator.

[0005] To address this, existing technologies propose directly connecting two oxygen delivery components, each connected to its respective adsorption tower and forming its own pressure equalization channel, to each other, and then connecting them together to a pressure equalization control valve. While this eliminates the risk of leakage due to hose aging, it also complicates the structure of the two oxygen delivery components and results in differences in pressure equalization during the bidirectional pressure equalization process, which is detrimental to the stable oxygen supply from the oxygen generator. Utility Model Content

[0006] The purpose of this invention is to overcome the problems of complex structure of oxygen delivery components and differences in pressure equalization effect in the bidirectional pressure equalization process in the pressure equalization control components of existing oxygen generators. This invention provides a pressure equalization control component for oxygen generators that simplifies the structure of oxygen delivery components and enables the bidirectional pressure equalization process to have the same pressure equalization effect, thereby achieving stable oxygen supply.

[0007] To achieve the above objectives, this utility model provides a pressure equalization control component for an oxygen generator, comprising:

[0008] A pressure equalizing valve seat having a first pressure equalizing channel and a second pressure equalizing channel;

[0009] A first module bracket and a second module bracket, symmetrically and sealingly connected to the pressure equalization valve seat, each having a first oxygen delivery channel and a second oxygen delivery channel for communication to a corresponding oxygen generating unit, and having an oxygen inlet and an oxygen outlet, the first pressure equalization channel being connected to the first oxygen delivery channel, and the second pressure equalization channel being connected to the second oxygen delivery channel; and,

[0010] A pressure equalization control valve is installed on the pressure equalization valve seat and has a connected state in which the first pressure equalization channel and the second pressure equalization channel are connected to each other through the pressure equalization control valve and an isolated state in which they are separated from each other.

[0011] Preferably, the first pressure equalization channel and the second pressure equalization channel are open at both ends of the pressure equalization valve seat and have the same flow cross-sectional area at corresponding positions. The first module bracket and the second module bracket have symmetrical structures and are correspondingly connected to both ends of the pressure equalization valve seat.

[0012] Preferably, the first module bracket and the second module bracket are connected to the pressure equalization valve seat at positions close to the oxygen inlet.

[0013] Preferably, the pressure equalization control valve is connected to one side of the pressure equalization valve seat, and along the direction from the portion connected to the pressure equalization valve seat to the corresponding oxygen outlet, the first oxygen delivery channel and the second oxygen delivery channel extend away from the pressure equalization control valve.

[0014] Preferably, the first oxygen delivery channel and the second oxygen delivery channel are each provided with a one-way valve that allows airflow to flow only in one direction toward the oxygen outlet.

[0015] Preferably, the pressure equalization control component further includes a throttling connection structure that keeps the oxygen inlets of the first oxygen delivery channel and the second oxygen delivery channel constantly connected.

[0016] Preferably, the throttling orifice diameter of the throttling connection structure is 0.1mm-3mm.

[0017] Preferably, the throttling connection structure includes a throttling bridge connecting the first module bracket and the second module bracket. The throttling bridge includes a flexible tube with its two ends respectively connected to the first module bracket and the second module bracket, and a throttling element installed in the flexible tube.

[0018] Preferably, the throttling connection structure is integrated within the pressure equalization valve seat and has a throttling orifice that allows the first pressure equalization channel and the second pressure equalization channel to communicate with each other.

[0019] A second aspect of this invention provides an oxygen generator including the aforementioned pressure equalization control components.

[0020] Through the above technical solution, the pressure equalization control component of this utility model provides a pressure equalization valve seat as the installation base. The pressure equalization control valve and oxygen delivery components such as the first module bracket and the second module bracket are respectively installed on the pressure equalization valve seat. Therefore, it is unnecessary to provide interconnection structures and vent holes for the pressure equalization control valve on the first and second module brackets; instead, it is only necessary to connect the oxygen inlet to the first and second pressure equalization channels, thus simplifying the structure. Simultaneously, since they are respectively connected to the pressure equalization valve seat, the first and second module brackets can be configured to have the same flow cross-section at corresponding positions, thereby achieving the same pressure equalization effect in the bidirectional pressure equalization process and realizing stable oxygen supply.

Detailed Implementation

[0029] The specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are for illustration and explanation only and are not intended to limit the scope of this utility model.

[0030] Reference Figures 1 to 3 As shown, a pressure equalization control component for an oxygen generator according to a preferred embodiment of the present invention includes a pressure equalization valve seat 1 and a first module support 3, a second module support 4, and a pressure equalization control valve 2 respectively connected to the pressure equalization valve seat 1. The pressure equalization valve seat 1 has a first pressure equalization channel 11 and a second pressure equalization channel 12; the first module support 3 and the second module support 4 are symmetrically and sealed to the pressure equalization valve seat 1, and each has a first oxygen delivery channel 31 and a second oxygen delivery channel 41 for connecting to a corresponding oxygen generating unit (such as a molecular sieve adsorption tower). The first oxygen delivery channel 31 has a first oxygen inlet 32 ​​and a first oxygen outlet 33, and the second oxygen delivery channel 41 has a second oxygen inlet 42 and a second oxygen outlet 43. The first pressure equalization channel 11 is connected to the first oxygen delivery channel 31, and the second pressure equalization channel 12 is connected to the second oxygen delivery channel 41. The equalizing control valve 2 has a connected state and an isolated state. In the connected state, the first equalizing channel 11 and the second equalizing channel 12 are connected to each other through the equalizing control valve 2. In the isolated state, the first equalizing channel 11 and the second equalizing channel 12 are not connected through the equalizing control valve 2. That is, the two ports of the equalizing control valve 2 that connect to the first equalizing channel 11 and the second equalizing channel 12 are isolated from each other within the equalizing control valve 2.

[0031] Therefore, when this pressure equalization control component is used in an oxygen concentrator employing a dual-tower adsorption-desorption cycle oxygen generation process, the oxygen inlets 32 and 42 of its first module support 3 and second module support 4 can be connected to the oxygen outlets of the corresponding adsorption towers, respectively. At a specific time in each oxygen generation cycle, the on / off state between the first pressure equalization channel 11 and the second pressure equalization channel 12 is switched by the pressure equalization control valve 2. The oxygen outlets of the two adsorption towers are connected through the pressure equalization control valve 2, supplying the high-concentration oxygen generated at the end of the adsorption cycle in one adsorption tower to another adsorption tower in the nitrogen removal cycle. This not only facilitates the desorption of the adsorption tower's sieve bed but also increases the initial oxygen concentration when entering the next adsorption cycle, thus ensuring a stable oxygen supply from the oxygen concentrator. At the same time, the oxygen generated by the adsorption tower in the oxygen generation (adsorption) cycle is output through the oxygen outlets 33 and 43 of the corresponding module support for storage in an oxygen storage tank or direct use by the patient.

[0032] Furthermore, by directly connecting the first module bracket 3 and the second module bracket 4 to the equalizing valve seat 1, the flexible hose, which is prone to leakage, is eliminated, reducing the space occupied in the oxygen generator. In particular, this equalizing control assembly provides the equalizing valve seat 1 as the mounting base. The equalizing control valve 2 and oxygen delivery components such as the first module bracket 3 and the second module bracket 4 are respectively installed on the equalizing valve seat 1. Therefore, there is no need to provide interconnection structures or vent holes for the equalizing control valve on the first module bracket 3 and the second module bracket 4; instead, their oxygen inlets only need to be connected to the first equalizing channel 11 and the second equalizing channel 12, thus simplifying the structure. Simultaneously, since they are respectively connected to the equalizing valve seat 1, the first module bracket 3 and the second module bracket 4 can be configured to have the same flow cross-section at corresponding positions, thereby achieving the same equalizing effect in the bidirectional equalizing process and realizing stable oxygen supply.

[0033] To facilitate the application of the pressure equalization control component of this invention to the limited space of portable oxygen concentrators, especially in the already cramped stacking space, the structure and relative arrangement of each component can be appropriately configured. In the preferred embodiment shown in the figure, the first pressure equalization channel 11 and the second pressure equalization channel 12 are open at both ends of the pressure equalization valve seat 1 and have the same flow cross-sectional area at corresponding positions. The first module bracket 3 and the second module bracket 4 have symmetrical structures and are correspondingly connected to both ends of the pressure equalization valve seat 1. This fully utilizes the width space of the oxygen concentrator, making the extension directions of the oxygen inlet to the oxygen delivery channel, the oxygen delivery channel to the oxygen outlet, and the pressure equalization channel in the module bracket different. This not only shortens the airflow path during the pressure equalization process and ensures the pressure equalization effect, but also facilitates the oxygen delivery channel and the pressure equalization channel to be located on the same plane, improving space utilization. Furthermore, since the first module support 3 and the second module support 4 have symmetrical structures and the first pressure equalization channel 11 and the second pressure equalization channel 12 have the same flow cross-sectional area at their corresponding positions, the oxygen output process and the bidirectional pressure equalization process have the same resistance conditions, thus ensuring a stable oxygen supply and the same pressure equalization effect.

[0034] In the preferred embodiment illustrated, the two ends of the equalizing valve seat 1 are respectively sealed and inserted into the first module bracket 3 and the second module bracket 4. A first sealing ring 13 is provided between the outer peripheral surface of the equalizing valve seat 1 and the inner peripheral surface of the first module bracket 3 and the second module bracket 4 to prevent air leakage. The two ends of the equalizing valve seat 1 may each have an insertion end. An annular groove for installing the first sealing ring 13 can be formed on the outer peripheral surface of the insertion end. The first sealing ring 13 is positioned within the annular groove and abuts against the inner peripheral surface of the first module bracket 3 and the second module bracket 4 at its radially outer end to achieve a sealed connection. The insertion end of the equalizing valve seat 1 may be made of a hard rubber material, while the first sealing ring 13 may be a sealing ring made of a soft material such as silicone, fluororubber, or nitrile rubber, as described later. In an alternative embodiment, the first module bracket 3 and the second module bracket 4 may be inserted into the equalizing valve seat 1, or the first module bracket 3 and the second module bracket 4 may be connected to the first equalizing channel 11 and the second equalizing channel 12.

[0035] The first module support 3 and the second module support 4 can be connected to the pressure equalization valve seat 1 at a position close to their respective oxygen inlets. Thus, oxygen output from one of the adsorption towers can enter the pressure equalization channel and then enter the other adsorption tower through a shorter path, effectively shortening the pressure equalization airflow path and improving compactness.

[0036] Furthermore, the equalizing control valve 2 can also be arranged within the plane of the first module bracket 3 and the second module bracket 4 to avoid occupying additional stacking space inside the oxygen concentrator. Specifically, in the illustrated preferred embodiment, the equalizing control valve 2 is connected to one side of the equalizing valve seat 1. Along the direction from the portion connected to the equalizing valve seat 1 to the corresponding oxygen outlet, the first oxygen delivery channel 31 and the second oxygen delivery channel 41 extend away from the equalizing control valve 2, thereby ensuring that the size of the equalizing control assembly is not excessive in any direction, which is suitable for miniaturization of the oxygen concentrator.

[0037] To prevent the delivered oxygen from flowing back through the first oxygen delivery channel 31 and the second oxygen delivery channel 41, each of the two channels can be equipped with a one-way valve 5 that allows airflow only to its oxygen outlet. In the preferred embodiment shown in the figure, the one-way valve 5 includes a one-way valve seat 51 and a one-way valve plate 52, which are sealed in the first oxygen delivery channel 31 and the second oxygen delivery channel 41 by a second sealing ring 7. The one-way valve seat 51 may have small holes. When gas passes through the small holes along the direction from the adsorption tower to the oxygen storage tank (from the oxygen inlet to the oxygen outlet of the module support), the airflow will blow up the fan-shaped soft rubber one-way valve plate 52, and oxygen will enter the oxygen storage tank. When the airflow flows back from the oxygen storage tank to the adsorption tower (from the oxygen outlet to the oxygen inlet of the module support), the airflow pressure will firmly press the one-way valve plate 52 against the one-way valve seat 51, thereby blocking the small holes on the one-way valve seat 51, thus realizing its one-way function. In alternative embodiments, the one-way valve 5 may also adopt other structural forms in the relevant prior art.

[0038] The sealing rings in the pressure equalization control components described above (such as the first sealing ring 13 and the second sealing ring 7) are gas path sealing elements and are usually made of soft materials, such as silicone, fluororubber, nitrile rubber, etc., to prevent unnecessary air leakage during operation.

[0039] Furthermore, the pressure equalization control component of this invention also includes a throttling connection structure that keeps the first oxygen inlet 32 ​​of the first oxygen delivery channel 31 and the second oxygen inlet 42 of the second oxygen delivery channel 41 constantly connected. For example, in Figures 1 to 3In the preferred embodiment shown, a throttling bridge 6 connects the first module support 3 and the second module support 4. The throttling bridge 6 includes a flexible tube 61 with its two ends connected to the first module support 3 and the second module support 4 respectively, and a throttling element 62 installed within the flexible tube 61. The flexible tube 61 can be made of silicone and connects to the first oxygen delivery channel 31 and the second oxygen delivery channel 41, allowing the first oxygen delivery channel 31 and the second oxygen delivery channel 41 to communicate with each other through a throttling orifice 63 defined by the throttling element 62. In the case where the aforementioned one-way valve 5 is provided, the throttling bridge 6 can be connected upstream of the one-way valve 5 to the corresponding first module support 3 and second module support 4. That is, the position of the throttling bridge 6 connecting to the first module support 3 and the second module support 4 is closer to the first oxygen inlet 32 ​​and the second oxygen inlet 42 relative to the one-way valve 5, so that the first oxygen inlet 32 ​​and the second oxygen inlet 42 remain constantly connected through the throttling bridge 6. Therefore, the oxygen produced by the adsorption tower during the adsorption cycle is partly stored in the oxygen storage tank or supplied to the patient through the oxygen outlet, and partly passes through the throttling bridge 6 to another adsorption tower to help it desorb nitrogen. This is beneficial for the adsorption tower in the desorption cycle to effectively adsorb and separate oxygen in the next cycle. This continuous connection is important for the performance of the oxygen concentrator. If it cannot desorb nitrogen well during the desorption cycle, the oxygen concentration produced in subsequent adsorption cycles will gradually decrease with each cycle. The throttling element 62 can be made of metal or plastic. Its pore size and processing precision have a significant impact on the performance of the oxygen concentrator. Generally, for home and portable oxygen concentrators, the pore size of the throttling orifice 63 should be between 0.1mm and 3mm.

[0040] Figures 4 to 6 This invention illustrates another preferred embodiment of a pressure equalization control component for an oxygen concentrator, which is combined with the aforementioned component. Figures 1 to 3 The first preferred embodiment is basically the same as described above; the differences will be explained below.

[0041] like Figures 1 to 3 As shown, in the first preferred embodiment, the first oxygen delivery channel 31 and the second oxygen delivery channel 41 are interconnected by a relatively independently arranged throttling bridge 6 to achieve backflushing during the desorption cycle. Thus, the first equalizing channel 11 and the second equalizing channel 12 are isolated from each other within the equalizing valve seat 1.

[0042] In contrast, Figures 4 to 6In the second preferred embodiment shown, the throttling and connecting structure is integrated within the pressure equalization valve seat 1 and has a throttling orifice 63 that allows the first pressure equalization channel 11 and the second pressure equalization channel 12 to communicate with each other, thus eliminating the need for a separate throttling bridge. With this arrangement, there is no need to form connectors for connecting hoses on the first module bracket 3 and the second module bracket 4. Furthermore, the integration of the pressure equalization control component can be further improved by directly installing the throttling element 62 into the pressure equalization valve seat 1 or by forming the throttling orifice 63 within the pressure equalization valve seat 1. This not only saves layout space but also reduces installation difficulty and facilitates improved production efficiency.

[0043] With the above-described configuration, the uniform control component of the preferred embodiment of this utility model has many advantages:

[0044] 1. Integrated Design: The uniform control component of this invention integrates components such as the equalizing valve seat, throttling element, and check valve, improving space utilization. This integrated design not only reduces the size of the equipment but also simplifies the installation and use process, reducing operational complexity and cost.

[0045] 2. Integration of Throttling Element and Pressure Equalizing Valve Seat: The uniform control component of this invention integrates the throttling element and pressure equalizing valve seat, eliminating the need for hoses and connectors, reducing the risk of leakage, and improving the stability of product oxygen concentration and quality reliability. This integrated design not only reduces the number of connecting parts but also improves the reliability and stability of the connection.

[0046] 3. In existing portable oxygen concentrators, components such as the equalizing valve and the throttling element are separate, requiring more time and effort during installation and use, increasing operational complexity and cost. This invention simplifies the installation and use process by integrating the equalizing valve and the throttling element, reducing operational complexity and cost.

[0047] 4. Improved purging function: By improving the structure and materials of the throttling bridge, the effectiveness and stability of the purging function are enhanced, thereby improving the oxygen concentration stability and quality reliability of the product. This improved design not only improves product performance but also enhances its operational stability and safety.

[0048] 5. This utility model proposes an integrated component that combines pressure equalization and purging functions, which can greatly improve the integration and miniaturization level of the equipment, while also increasing space utilization. This will greatly promote the further development of the portable oxygen concentrator manufacturing industry and meet the market demand for efficient, small, and portable oxygen concentrators.

[0049] Based on this, the present invention also provides an oxygen generator including the above-mentioned pressure equalization control components.

[0050] The preferred embodiments of the present invention have been described in detail above with reference to the accompanying drawings; however, the present invention is not limited thereto. Within the scope of the technical concept of the present invention, various simple modifications can be made to the technical solution of the present invention, including combinations of various specific technical features in any suitable manner. To avoid unnecessary repetition, the present invention will not describe the various possible combinations separately. However, these simple modifications and combinations should also be considered as the content disclosed in the present invention and are all within the protection scope of the present invention.
