Description

Technical Field

[0001] This utility model relates to the field of oxygen production technology, and more specifically to an oxygen output component for an oxygen generator and an oxygen generator including the oxygen output component. Background Technology

[0002] In recent years, with the improvement of living standards, people have paid more and more attention to their own health. Among them, oxygen therapy and oxygen health care, as new technologies to enhance physical fitness and prevent diseases, are gradually being accepted and promoted. The home oxygen concentrator industry has also flourished and shown a strong growth trend, and is widely used for cardiovascular diseases, respiratory diseases, geriatric diseases, children's respiratory infections, sleep-related hypoxemia, etc.

[0003] As a medical product, home oxygen concentrators need to balance oxygen therapy effectiveness and comfort. This is especially important for users who need to use them for extended periods. The stability of oxygen delivery during inhalation can affect sleep quality and comfort, and may also place an additional burden on users with cardiovascular diseases. Therefore, maintaining a stable oxygen flow rate without compromising the oxygen production process and capacity is crucial for improving the user experience.

[0004] Currently, most oxygen concentrators on the market are continuous oxygen supply concentrators. They separate nitrogen and oxygen in the air by adsorbing nitrogen through molecular sieves, thereby obtaining high-purity oxygen. The oxygen is stored in an oxygen storage tank. When in use, the output oxygen pressure is adjusted by a pressure regulating valve, which in turn changes the output flow rate. The output oxygen is provided to the user through an oxygen sensor and an oxygen outlet.

[0005] Pulsed oxygen concentrators are a recently developed type of oxygen concentrator that delivers oxygen based on the user's breathing rate. Oxygen is supplied when the user inhales and stopped when the user exhales, thus providing an appropriate amount of oxygen and improving user comfort compared to continuous oxygen concentrators. However, during operation, the oxygen tank in a pulsed oxygen concentrator delivers oxygen through a pulse valve according to the user's breathing rate. This results in fluctuating oxygen flow rates with each delivery, significantly reducing user comfort.

[0006] To address the issue of fluctuating oxygen flow rates in pulse oxygen concentrators, the current solution is to continue using the pressure regulating valve employed in continuous oxygen concentrators. However, most pressure regulating valves on the market are only compatible with continuous oxygen supply and have low or no compatibility with pulse oxygen supply. Furthermore, the large size of pressure regulating valves makes them difficult to assemble in confined spaces, limiting their application. In addition, as a crucial component of oxygen concentrators, the pressure regulating valve accounts for a significant portion of the overall cost. Utility Model Content

[0038] Techniques, methods, and equipment known to those skilled in the art may not be discussed in detail, but where appropriate, they should be considered part of the specification.

[0039] This utility model provides an oxygen outlet assembly for an oxygen generator. The oxygen outlet assembly includes a throttling component 1 and an oxygen outlet pipe. The inlet end of the oxygen outlet pipe is used to connect to the oxygen outlet 111 of the oxygen storage tank 11 of the oxygen generator, and the outlet end of the oxygen outlet pipe is used to connect to the oxygen user. The throttling component 1 is disposed between the inlet end of the oxygen outlet pipe and the oxygen outlet 111 or disposed inside the oxygen outlet pipe and close to the oxygen outlet 111 to adjust the oxygen flow rate at the oxygen outlet 111.

[0040] In pulse-type oxygen generators, the high pressure inside the oxygen storage tank 11 results in a high oxygen flow rate. This is detrimental to the controller's ability to control the opening and closing time of the pulse valve on the storage tank; the higher the flow rate, the faster the pulse valve's response must be, requiring a more precise and faster-responding pulse valve. Furthermore, the amount of oxygen output fluctuates significantly with each cycle. This invention addresses this by connecting an oxygen outlet assembly, including a throttling component 1, to the oxygen outlet 111 of the storage tank 11. The throttling component 1 reduces the oxygen flow rate at the outlet 111, making the oxygen delivery more precise and stable each time. This allows for compatibility with lower-precision pulse valves while achieving the same level of accuracy. Additionally, this oxygen outlet assembly, as a novel alternative to the pressure regulating valve, offers advantages such as high adaptability, simple structure, and low cost.

[0041] Of course, in order to facilitate oxygen supply to the oxygen-consuming end, the oxygen supply assembly may also include an oxygen outlet 10, which is connected to the outlet end of the oxygen supply pipe.

[0042] In order to accommodate the oxygen outlet assembly in confined installation spaces, in some implementations the oxygen outlet pipe is a flexible tube, such as a silicone tube.

[0043] When the oxygen outlet pipe is a flexible hose, the high-pressure gas in the oxygen storage tank 11 will vibrate or expand when it flows through the oxygen outlet hose, resulting in unstable gas flow rate. Therefore, by setting a throttling component 1 at the inlet end of the oxygen outlet pipe, the oxygen outlet flow rate is reduced to stabilize the airflow at the inlet end of the oxygen outlet pipe, thereby reducing the impact on the downstream section of the oxygen outlet pipe and the components connected to the pipe.

[0044] Furthermore, the oxygen delivery assembly may also include a flow stabilizing component 9. The flow stabilizing component 9 can be located between the outlet end of the oxygen delivery tube and the oxygen outlet nozzle 10, or located inside the oxygen delivery tube and close to the oxygen outlet nozzle 10. Since the pulse oxygen generator provides pulsed oxygen supply based on human respiration, that is, oxygen is supplied when the human body inhales and not when exhaled, the flow rate increases momentarily when oxygen is released during inhalation. This can cause vibration or pipe expansion at the outlet end of the oxygen delivery tube, resulting in unstable gas flow rate and making it impossible to control the oxygen output as expected. By setting the flow stabilizing component 9, the flow stabilizing component 9, the oxygen delivery tube, and the throttling component 1 together form a device for temporarily storing oxygen. After the high-pressure gas flows through this section, it is stored and then released after a delay, thereby achieving a flow stabilizing effect. This makes the delivered oxygen more stable and improves user comfort.

[0045] In this invention, the throttling component 1 and the flow stabilizing component 9 can have any suitable structure. In some embodiments, see [reference needed]. Figure 2 The throttling component 1 is a cylindrical throttling bridge with a central through-hole. The diameter of the central through-hole is smaller than the diameter of the oxygen outlet 111, thus limiting the oxygen output and pressure. See also Figure 3 The flow stabilizing component 9 is a cylindrical flow stabilizing bridge with a central through hole. The diameter of the central through hole of the flow stabilizing component 9 is larger than the diameter of the central through hole of the throttling component 1 and / or smaller than the inner diameter of the oxygen outlet nozzle 10. The ratio between the diameter of the throttling component 1 and the diameter of the flow stabilizing component 9 can be determined according to the required flow rate and output gas pressure.

[0046] When the oxygen outlet pipe is a flexible tube, the outer diameter of the throttling component 1 and the flow stabilizing component 9 can be larger than the inner diameter of the oxygen outlet pipe. This allows the throttling component 1 and the flow stabilizing component 9 to be directly installed inside the oxygen outlet pipe. The throttling component 1 and the flow stabilizing component 9 can be locked inside the oxygen outlet pipe to prevent them from moving under the blowing of the airflow.

[0047] In this invention, the oxygen outlet assembly may further include an oxygen sensor 4. The oxygen sensor 4 is connected to the oxygen outlet pipe and located downstream of the throttling component 1. The oxygen sensor 4 can be used to monitor the flow rate and / or concentration of oxygen in the oxygen outlet pipe. Specifically, in some embodiments, there may be one oxygen sensor 4, which is used to monitor the flow rate or concentration of oxygen in the oxygen outlet pipe. In other embodiments, there may be two oxygen sensors 4, which can be used to monitor the flow rate and concentration of oxygen in the oxygen outlet pipe respectively. The oxygen sensor 4 is a highly sensitive electronic component, and unstable flow rate will affect the data output by the oxygen sensor 4. A relatively high flow rate will affect the service life of the oxygen sensor 4. This invention reduces the oxygen flow rate at the oxygen outlet of the oxygen storage tank by setting the throttling component 1, and also protects the downstream oxygen sensor 4, thereby improving the service life of the oxygen sensor 4.

[0048] In this invention, the oxygen outlet tube can be composed of multiple flexible sections. Specifically, as shown... Figure 1 As shown, the oxygen outlet pipe may include a first hose 3 and a second hose 5. The inlet end of the first hose 3 is connected to the oxygen outlet 111, and the outlet end of the second hose 5 is connected to the oxygen nozzle 10. The oxygen sensor 4 is connected between the outlet end of the first hose 3 and the inlet end of the second hose 5. In other words, the throttling component 1, the oxygen sensor 4, and the flow stabilizing component 9 are connected by hoses. This connection method not only allows the oxygen outlet assembly to adapt to more scenarios but also facilitates installation and maintenance, while improving work efficiency.

[0049] In this invention, the oxygen output assembly may further include a bacterial filter 2, which can be installed on the oxygen output pipe to purify oxygen. Specifically, as shown... Figure 1 As shown, the bacterial filter 2 can be installed close to the throttling component 1. To facilitate maintenance and replacement of the bacterial filter 2, it is preferably detachably installed on the oxygen outlet pipe. For example, both ends of the bacterial filter 2 can be provided with pipe interfaces that can be inserted into the oxygen outlet pipe.

[0050] In this invention, the oxygen delivery component may further include a differential pressure sensor 8, which is connected to the oxygen delivery pipe and used to monitor the pressure difference between the gas pressure inside the oxygen delivery pipe and the external atmospheric pressure. The differential pressure sensor 8 can communicate with the controller of the oxygen generator. When the user inhales, the differential pressure sensor 8 detects a negative pressure signal in the oxygen delivery pipe and sends the negative pressure signal to the controller. The controller then controls the pulse valve on the oxygen storage tank to open and deliver oxygen based on the negative pressure signal.

[0051] In this invention, the oxygen outlet assembly may also include a pressure relief valve 7, which is connected to the oxygen outlet pipe. When the pressure in the oxygen outlet pipe exceeds the safe pressure value range set by the pressure relief valve, the pressure relief valve opens to discharge the high-pressure gas in the oxygen outlet pipe, thereby protecting components such as the differential pressure sensor and oxygen sensor from high-pressure damage or abnormal accuracy.

[0052] To enable the connection between the differential pressure sensor 8 and the pressure relief valve 7 and the oxygen outlet pipe, and to simplify the structure and facilitate maintenance, as follows: Figure 1 As shown, the oxygen supply assembly may include a four-way connector 6, which is connected to the oxygen supply pipe through two of its ports, and the other two ports of the four-way connector 6 are connected to a pressure relief valve 7 and a differential pressure sensor 8, respectively.

[0053] The oxygen delivery component provided by this utility model organically reduces the flow rate output from the oxygen storage tank within the limited space of a pulse oxygen generator. By applying relatively small throttling and flow stabilizing components and a flexible hose structure, it not only solves the assembly problem in a confined space but also saves costs, making the delivered oxygen more precise and stable, and bringing users a more comfortable "oxygen therapy" experience.

[0054] In this invention, a throttling component 1 is first installed at the inlet end of the oxygen outlet pipe (from the oxygen storage tank 11 to the user end) along the direction of airflow in the oxygen outlet end of the pulse oxygen generator. The throttling component 1 reduces the flow velocity at the inlet end of the hose, preventing the high-pressure gas flow from the oxygen storage tank 11 from directly passing through the outlet hose. This avoids unstable gas flow velocity due to hose vibration or pipe expansion, thus ensuring more accurate and stable oxygen delivery each time. It also reduces the precision requirements of the pulse valve, allowing for compatibility with a wider range of pulse valves. Simultaneously, the stable airflow velocity at the beginning of the outlet hose protects the sensor connected to the middle section of the outlet pipe, preventing impact from high flow velocities and extending the sensor's lifespan. Furthermore, since pulse-type oxygen concentrators only supply oxygen when the user inhales, the flow rate increases momentarily upon inhalation, causing instability at the outlet of the oxygen delivery tube. This solution addresses this by incorporating a flow stabilizing component 9 at the outlet of the oxygen delivery tube to ensure the stability of the flow rate and prevent excessive flow from impacting the hose. This is particularly beneficial for pulse-type oxygen concentrators with equivalent large capacities, such as 1L equivalent to 3L or 5L, or 5L equivalent to 10L. The stabilizing effect of the flow stabilizing component 9 on airflow stability during inhalation is even more pronounced when the oxygen output is high. Additionally, the flow stabilizing component 9, the oxygen delivery tube, and the throttling component 1 together form a temporary oxygen storage device. After high-pressure gas flows through this section, oxygen is stored and delayed before being delivered to the user, thus buffering and stabilizing the flow. This results in a more stable oxygen delivery and improved user comfort.

[0055] Another aspect of this utility model provides an oxygen generator, see [link to relevant documentation]. Figure 1 The oxygen generator includes an oxygen storage tank 11 and the aforementioned oxygen outlet assembly, wherein the oxygen outlet assembly is connected to the oxygen outlet 111 of the oxygen storage tank 11.

[0056] like Figure 1The illustrated embodiment shows an oxygen concentrator comprising an oxygen storage tank 11 and an oxygen outlet assembly connected to an oxygen outlet 111 of the oxygen storage tank 11. The oxygen outlet assembly includes a throttling component 1, a bacterial filter 2, a first hose 3, an oxygen sensor 4, a second hose 5, a four-way connector 6, a pressure relief valve 7, a differential pressure sensor 8, a flow stabilizing component 9, and an oxygen outlet nozzle 10. The oxygen produced by the oxygen concentrator is stored in the oxygen storage tank 11. When a user inhales, the differential pressure sensor 8 detects a negative pressure signal in the oxygen outlet hose and sends this signal to the controller. The controller, based on the negative pressure signal, controls the pulse valve 112 on the oxygen storage tank 11 to open. The oxygen in the oxygen storage tank 11 flows out through the oxygen outlet 111, first being slowed down by the throttling component 1, then passing through the bacterial filter 2 and the first hose 3 before entering the oxygen sensor 4. After passing through the oxygen sensor 4, the oxygen then passes through the second hose 5, the flow stabilizing component 9, and the oxygen outlet nozzle 10, ultimately being delivered to the user.
