Description

Technical Field

[0001] This utility model relates to the field of medical device technology, and in particular to a long-lasting and durable emergency oxygen concentrator. Background Technology

[0002] An oxygen concentrator is a device that produces oxygen through physical or chemical methods. It is mainly used in medical care, home health care, and some industrial settings. In the medical field, oxygen concentrators can help people with hypoxia, such as those with emphysema or cardiovascular and cerebrovascular diseases, to relieve symptoms such as difficulty breathing. They can also provide oxygen supplementation for people with altitude sickness, pregnant women, and others. Common emergency oxygen concentrators usually consist of an air compressor, molecular sieve, filtration mechanism, humidification bottle, and control system.

[0003] In existing oxygen concentrators, the filtration mechanism is often integrated with the main unit. When the filter material becomes clogged, the entire main unit needs to be removed for cleaning, which makes maintenance cumbersome and affects the long-term use of the oxygen concentrator. Utility Model Content

[0004] To overcome the above shortcomings, this utility model provides a long-lasting and durable emergency oxygen concentrator, which aims to improve the problem of inconvenient maintenance caused by the fixed filter mechanism and main unit in existing oxygen concentrators.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a long-lasting and durable emergency oxygen concentrator, comprising:

[0006] A first outer shell, a second outer shell fixedly connected to one side surface of the first outer shell, an input pipe and an output pipe fixedly connected to the inner wall of the first outer shell respectively, and a third outer shell snapped onto the other side surface of the first outer shell, with a connecting mechanism provided on the surface of the third outer shell;

[0007] A dustproof housing has an air inlet on its surface, a connector is threaded to the top of the dustproof housing, a filter tube is fixedly connected to the inner wall of the connector, a fixing ring is threaded to the bottom of the dustproof housing, a fixing member is attached to the top of the fixing ring, and the fixing member is fixedly connected to the first housing.

[0008] The above technical solution involves externalizing the filter mechanism, allowing it to be connected separately to the main body of the oxygen concentrator. This facilitates quick replacement and maintenance of the filter mechanism, thereby improving the durability of the oxygen concentrator.

[0009] Preferably, the oxygen generator further includes a limiting post, which is threadedly connected to the inner wall of the dustproof housing. A filter material is attached to the inner surface of the limiting post, and the bottom surface of the filter material is attached to the bottom of the inner wall of the dustproof housing.

[0010] The above technical solution allows the filter media to be released from its fixed state by using the limiting post, thus preventing the user's hands from directly contacting the filter media.

[0011] Preferably, the connecting mechanism includes a enclosure, which is fixedly connected to the surface of the third outer shell. A heater is attached to the inner side of the enclosure, and a humidification bottle is attached to the top of the heater. A protective baffle is attached to the inner surface of the third outer shell, and the protective baffle is fixedly connected to both the first and second outer shells.

[0012] Through the above technical solution, the enclosure can tightly support the humidification bottle and heater, thereby preventing the humidification bottle and heater from shifting due to vibration during the operation of the oxygen generator.

[0013] Preferably, the bottom of the third outer shell is provided with a receiving groove for placing the humidification bottle, and the heater is fixedly connected to the bottom of the inner wall of the receiving groove;

[0014] The above technical solution prevents the humidification bottle from shaking during the movement or operation of the oxygen generator, ensuring smooth oxygen humidification.

[0015] Preferably, the inner wall of the input pipe is threaded with a first connector, the surface of the first connector is engaged with a second connector, the surface of the filter pipe is fixedly connected with a sealing ring, and the outer wall surface of the sealing ring is respectively in contact with the inner walls of the second connector and the first connector;

[0016] With the above technical solution, when the first connector or input tube is damaged, the input tube can be separated from the first connector by rotation, and then replaced.

[0017] Preferably, a cavity is formed between the first outer shell and the second outer shell, and a compressor and a molecular sieve are disposed inside the cavity;

[0018] The above technical solution isolates the compressor and molecular sieve from the external environment and other auxiliary components, thereby reducing the interference of external factors on the operation of the compressor and molecular sieve.

[0019] Preferably, an air supply pipe is fixedly connected to the top of the humidification bottle, and the air supply pipe is fixedly connected to the output pipe. A connection hole is provided on the surface of the protective baffle, and the connection hole is used to fix the air supply pipe.

[0020] The above technical solution, through the combined action of the protective baffle, humidification bottle, and output pipe, achieves the positioning of the entire gas delivery pipe, further enhancing the stability of the gas delivery pipe position.

[0021] Preferably, the third outer shell surface is provided with a control panel, which is used to control the operation of the oxygen generator;

[0022] The above technical solution, which connects the control panel to the third casing, allows users to adjust the oxygen concentrator's operating status according to their actual needs, meeting oxygen requirements in different scenarios and improving operational convenience.

[0023] This utility model has the following beneficial effects:

[0024] 1. In this utility model, the filter material inside the dustproof shell is fixed to the outside of the machine body by a fastener, which allows the oxygen concentrator to quickly disassemble the filter mechanism, reduces the long-term maintenance cost of the oxygen concentrator, and improves the durability of the oxygen concentrator. When replacing the filter material, the filter material can be fixed by rotating the limiting post to release the limiting post, avoiding direct contact between the user's hands and the filter material.

[0025] 2. In this utility model, the temperature inside the humidification bottle is controlled by attaching the bottom of the humidification bottle to the heater, which avoids the oxygen output temperature being too low and causing respiratory tract irritation. The protective baffle separates the humidification bottle from other internal structures of the oxygen generator, which prevents the oxygen generator from being affected by leakage of the humidification bottle due to accidents.

[0032] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0033] Example 1:

[0034] Reference Figures 1-2 One embodiment of this utility model is a long-lasting and durable emergency oxygen concentrator, comprising:

[0035] A first outer shell 1, a second outer shell 2 is fixedly connected to one side surface of the first outer shell 1, an input pipe 4 and an output pipe 21 are fixedly connected to the inner wall of the first outer shell 1 respectively, a third outer shell 3 is snapped to the other side surface of the first outer shell 1, and a connecting mechanism is provided on the surface of the third outer shell 3;

[0036] Dustproof housing 10, with an air inlet 14 on the surface of dustproof housing 10, a connector 9 threadedly connected to the top of dustproof housing 10, a filter tube 8 fixedly connected to the inner wall of connector 9, a fixing ring 11 threadedly connected to the bottom of dustproof housing 10, a fixing member 12 attached to the top of fixing ring 11, and a fixing member 12 fixedly connected to the first housing 1.

[0037] Specifically, external air is introduced through the air inlet 14 on the surface to provide raw materials for the oxygen generation process. After the external air enters, it is filtered by the filter material 15 to prevent impurities in the air from affecting the internal structure of the oxygen generator.

[0038] Through the combined action of the retaining ring 11 and the fixing part 12, the dustproof shell 10 can be fixed to the main body of the oxygen generator, avoiding the impact of vibration during equipment operation on the dustproof shell 10, ensuring the stability of the air intake and filtration process, and at the same time, the dustproof shell 10 can be quickly separated from the machine body by disassembling the retaining ring 11 when maintenance is required.

[0039] Reference Figure 4 The connecting mechanism includes a enclosure 18, which is fixedly connected to the surface of the third outer shell 3. A heater 17 is attached to the inner side of the enclosure 18, and a humidification bottle 16 is attached to the top of the heater 17. A protective baffle 19 is attached to the inner surface of the third outer shell 3, and the protective baffle 19 is fixedly connected to both the first outer shell 1 and the second outer shell 2.

[0040] Specifically, by having the top of the heater 17 fit in contact with the humidification bottle 16, the heat generated by the heater 17 can be directly transferred to the humidification bottle 16, keeping the oxygen output from the humidification bottle 16 at a suitable temperature and preventing low-temperature oxygen from causing discomfort to the user's respiratory tract.

[0041] Reference Figure 4 The bottom of the third outer shell 3 is provided with a receiving groove for placing the humidification bottle 16. The heater 17 is fixedly connected to the bottom of the inner wall of the receiving groove.

[0042] Specifically, the humidification bottle 16 can fit snugly against the inner wall of the receiving tank, which makes the humidification bottle 16 more stable when placed, while making the overall layout of the oxygen generator more compact and reasonable, and improving the space utilization of the equipment.

[0043] Reference Figure 2 The inner wall of the input pipe 4 is threaded with a first connector 5, and the surface of the first connector 5 is snapped with a second connector 6. The surface of the filter pipe 8 is fixedly connected with a sealing ring 7, and the outer wall surface of the sealing ring 7 is respectively attached to the inner wall of the second connector 6 and the first connector 5.

[0044] Specifically, the first connector 5 is surface-locked to the second connector 6, enabling the first connector 5 and the second connector 6 to quickly connect, shortening the connection time between the input pipe 4 and the filter pipe 8. The mechanical limit formed by the locking connection can prevent relative displacement between the second connector 6 and the first connector 5 in the axial direction, ensuring the stability of the airflow channel. At the same time, since the input pipe 4 is threaded to the first connector 5, the filter pipe 8 or related components can be quickly separated when maintenance is required, enhancing the maintainability of the equipment.

[0045] Reference Figure 4 A cavity is formed between the first outer shell 1 and the second outer shell 2, and a compressor and a molecular sieve are installed inside the cavity;

[0046] Specifically, the protective baffle 19 is fixedly connected to the first outer shell 1 and the second outer shell 2, separating the internal space of the third outer shell 3 from the cavity formed by the first outer shell 1 and the second outer shell 2. This allows components such as the humidification bottle 16 and the heater 17 to be in relatively independent spaces from core oxygen-generating components such as the compressor and molecular sieve, preventing liquid from seeping into the core component area when the humidification bottle 16 leaks accidentally, thus reducing the risk of damage to the core components.

[0047] Reference Figure 4 A gas supply pipe 20 is fixedly connected to the top of the humidification bottle 16. The gas supply pipe 20 is fixedly connected to the output pipe 21. A connection hole is provided on the surface of the protective baffle 19 for fixing the gas supply pipe 20.

[0048] Specifically, the humidification bottle 16 is fixedly connected to the air supply pipe 20, so that the humidified oxygen can be output through the air supply pipe 20. The air supply pipe 20 is fixed through the connection hole to prevent it from shifting or shaking due to vibration or airflow impact during equipment operation, ensuring that the air supply pipe 20 always stays on the preset path and avoids friction or collision with other components.

[0049] Reference Figure 4 The third outer shell 3 has a control panel on its surface, which is used to control the operation of the oxygen generator;

[0050] Specifically, the control panel allows users to control various components inside the oxygen generator, enabling them to intuitively understand the equipment status and centrally regulate the oxygen production process.

[0051] Example 2:

[0052] Reference Figure 3 The oxygen generator also includes a limiting post 13, which is threadedly connected to the inner wall of the dustproof housing 10. A filter material 15 is attached to the inner surface of the limiting post 13, and the bottom surface of the filter material 15 is attached to the bottom of the inner wall of the dustproof housing 10.

[0053] Specifically, the inner surface of the limiting post 13 is attached to the filter material 15, so that the limiting post 13 fixes the filter material 15 inside the dustproof housing 10 by squeezing. When replacing the filter material 15, the limiting post 13 can be rotated to release the fixing of the limiting post 13 to the filter material 15, preventing the hand from contacting the filter material 15 and causing the dust and impurities attached to the filter material 15 to contaminate the hand. At the same time, it avoids the hand touching the new filter material 15, which may cause deformation or contamination, and ensures that the filtration effect of the new filter material 15 is not affected after installation.

[0054] Working principle: The oxygen generator uses fastener 12 to fix the filter material 15 inside the dustproof shell 10 to the outside of the machine body, which allows the oxygen generator to quickly disassemble the filter mechanism and reduce the long-term maintenance cost of the oxygen generator. The input pipe 4 and the filter pipe 8 are quickly connected through the first connector 5 and the second connector 6, which shortens the connection time between the input pipe 4 and the filter pipe 8. At the same time, the sealing ring 7 further ensures the airtightness of the airflow channel.

[0055] On the other hand, by attaching the bottom of the humidification bottle 16 to the heater 17, the internal temperature of the humidification bottle 16 can be controlled, thereby avoiding respiratory irritation caused by excessively low oxygen output temperature. By connecting the humidification bottle 16 to the third outer shell 3 and separating the humidification bottle 16 from other internal structures of the oxygen generator through the protective baffle 19, it is possible to prevent the oxygen generator from being affected by leakage of the humidification bottle 16 due to accidents.

[0056] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
