Description

Technical Field

[0001] This utility model relates to the technical field of oxygen generators, and in particular to an oxygen generator gas storage tank. Background Technology

[0002] Small portable oxygen concentrators primarily utilize molecular sieve oxygen generation technology. These concentrators employ a pressurized adsorption and atmospheric desorption method, with two adsorption towers performing the same cyclic process to achieve continuous gas supply. Molecular sieve oxygen concentrators are widely used in medical treatment and home healthcare. The gas storage tank is an internal component of the concentrator used to store the oxygen separated by the molecular sieve.

[0003] Portable oxygen concentrators are lightweight and small devices, which necessitates reducing the weight of the equipment. As a pressure storage container, the gas storage tank needs to have a certain degree of rigidity and strength. Existing technologies typically use metal tank structures, which are reliable in strength but heavy. If plastic materials are used, they are lightweight but easily deformed. Summary of the Invention

[0004] In order to overcome the above-mentioned problems in the prior art, this utility model proposes an oxygen generator gas storage tank. By using a first partition and a second partition respectively set on the first shell and the second shell, the rigidity of the overall chamber is strengthened, ensuring that the gas storage tank will not deform; the gap between the first partition and the second partition ensures the normal flow of air in the gas storage tank.

[0005] The technical solution adopted by this utility model to solve its technical problem is: an oxygen generator gas storage tank, including a shell, the shell comprising:

[0006] The first housing and the second housing are detachably connected;

[0007] The first partition and the second partition are respectively disposed inside the first shell and the second shell, and respectively divide the first shell and the second shell into several independent sections;

[0008] A gap is provided between the first partition and the second partition, and the gap enables communication between the independent sections within the first housing and the second housing.

[0009] In the aforementioned oxygen generator storage tank, the first partition and the second partition are symmetrically arranged, and the sum of the heights of the first partition and the second partition is less than the thickness of the shell.

[0010] In the aforementioned oxygen generator gas storage tank, the first partition and the second partition are offset, with the height of the first partition being less than the thickness of the shell, and the height of the second partition being less than the thickness of the shell.

[0011] In the oxygen generator storage tank described above, the first housing and the second housing are detachably connected by protrusions and slots.

[0012] In the aforementioned oxygen generator gas storage tank, an adhesive is applied between the protrusion and the slot.

[0013] In the aforementioned oxygen generator gas storage tank, both the first partition and the second partition have a mesh structure.

[0014] In the aforementioned oxygen generator storage tank, the several independent compartments are of equal volume.

[0015] The oxygen generator storage tank described above has a first slot and a second slot on one side of the shell, from top to bottom; the first slot has a pressure sensor interface; and the second slot has an oxygen injection valve assembly.

[0016] In the aforementioned oxygen generator gas storage tank, the first slot and the second slot are arranged in a stepped structure.

[0017] The aforementioned oxygen generator gas storage tank also includes:

[0018] The atomizing valve seat is located at the front end of the oxygen injection valve assembly, and its upper end face is flush with the upper end face of the oxygen injection valve assembly.

[0019] The beneficial effects of this utility model are: the rigidity of the overall chamber is enhanced by the first and second partitions respectively set on the first and second shells, ensuring that the gas storage tank will not deform; the gap between the first and second partitions ensures the normal flow of air in the gas storage tank.

[0020] The connection between the first and second housings is made by plugging them together, which enables quick connection and fixation and improves installation efficiency. The stepped structure allows for the functional layout of each step, which simplifies the pipeline connection and makes the internal structure of the oxygen generator more compact.

[0021] By integrating the oxygen injection valve assembly and the atomizing valve seat onto the gas storage tank, multiple functions are achieved in one unit; the upper surfaces of the oxygen injection valve and the atomizing valve are parallel and form a stepped structure, providing installation space for the solenoid valves that control the switching of the corresponding gas path.

[0031] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be described in detail below with reference to the accompanying drawings and specific embodiments.

[0032] This utility model discloses an oxygen generator gas storage tank, the structure of which is as follows: Figure 1 As shown, the device includes a housing, which comprises: a first housing 1 and a second housing 2, which are detachably connected; a first partition and a second partition 3, which are respectively disposed within the first housing 1 and the second housing 2, and respectively divide the first housing 1 and the second housing 2 into several independent sections; and a gap, which is disposed between the first partition and the second partition 3, and through the gap, connects the independent sections within the first housing 1 and the second housing 2.

[0033] This invention strengthens the overall rigidity of the gas storage tank by setting a first partition and a second partition 3 on the first housing 1 and the second housing 2, reducing the deformation of the first housing 1 and the second housing 2 caused by pressure. By setting a gap between the first partition and the second partition 3, gas movement is facilitated, allowing oxygen to quickly diffuse into each independent section inside the gas storage tank.

[0034] To facilitate gas flow within the gas storage tank, in one embodiment, the first partition and the second partition 3 can be symmetrically arranged, with the sum of their heights being less than the thickness of the shell. In another embodiment, the first partition and the second partition 3 can be staggered, with the height of the first partition being less than the thickness of the shell, and the height of the second partition being less than the thickness of the shell. It should be noted that the height of the first partition is the distance from its outer end face to the inner end face of the first shell 1, the height of the second partition 3 is the distance from its outer end face to the inner end face of the second shell 2, and the thickness of the shell is the vertical distance from the inner end face of the first shell 1 to the inner end face of the second shell 2 after the first shell 1 and the second shell 2 are joined together.

[0035] In one embodiment, to facilitate the processing and assembly of the gas storage tank, the first housing 1 and the second housing 2 of the gas storage tank are detachably connected by a protrusion and a slot. Furthermore, to ensure a more secure connection between the first housing 1 and the second housing 2 and to prevent excessive pressure inside the gas storage tank from causing leakage due to a poor seal between the first housing 1 and the second housing 2, an adhesive is applied between the protrusion and the slot.

[0036] In one embodiment, to further enhance the strength of the gas storage tank, both the first partition and the second partition 3 are arranged in a grid structure. That is, a plurality of intersecting first partitions are provided inside the first shell 1, and a plurality of intersecting second partitions 3 are provided inside the second shell 2. Furthermore, the first partitions and the second partitions 3 divide the tank into several independent sections with equal areas. This arrangement not only reinforces the first shell 1 and the second shell 2, but also ensures uniform stress distribution inside the gas storage tank due to equal areas, preventing leakage or rupture of the first shell 1 and / or the second shell 2 caused by excessive local stress.

[0037] In one embodiment, in order to provide space for the oxygen concentration pipe 11 of the oxygen generator and various pipelines and installation valves, and at the same time to make the internal space of the oxygen generator more compact, a first slot and a second slot are provided on one side of the gas storage tank from top to bottom, and the first slot and the second slot are in a stepped structure.

[0038] In one embodiment, to make the internal structure of the oxygen concentrator more compact and save on pipeline connections, a pressure sensor interface 7 is provided on the first slot of the gas storage tank. The pressure sensor is located on the electronic control board 10 on the top of the oxygen concentrator. By setting the pressure sensor interface 7 on the first slot, the pipeline connections inside the oxygen concentrator are simplified, making the internal structure of the oxygen concentrator more compact and the layout more reasonable.

[0039] In one embodiment, the second slot is provided with an oxygen injection valve assembly 6. The gas output from the gas storage tank can be output to the oxygen concentration pipe 11 through the oxygen injection valve assembly 6 and delivered to the user from the oxygen outlet 18. This not only saves on pipeline connections but also provides space for the installation of the oxygen injection valve assembly 6, making the internal structure of the oxygen generator more compact and the layout more reasonable, which is conducive to the miniaturization of the oxygen generator.

[0040] Oxygen injection valve assembly 6 includes an oxygen injection valve seat and a first solenoid valve. The oxygen injection valve seat has, from right to left, a first interface 6-1, a second interface 6-2, and a third interface 6-3 (e.g., ...). Figure 2-3 As shown, a first solenoid valve is installed on the oxygen injection valve seat. The airflow port of the first solenoid valve corresponds to the three ports on the oxygen injection valve seat. The first solenoid valve is a two-position three-way solenoid valve. When the first solenoid valve is open, the first port 6-1 and the third port 6-3 of the oxygen injection valve seat are connected. The third port 6-3 is connected to the oxygen outlet 6-4 of the oxygen injection valve seat. The oxygen outlet 6-4 is connected to the oxygen concentration pipe 11. Oxygen is delivered to the user through the oxygen outlet 6-4 → oxygen concentration pipe 11 → oxygen nozzle 18. When the first solenoid valve is closed, the second port 6-2 is connected to the third port 6-3. The other end of the second port 6-2 is connected to the breathing sensor through the breathing sensor interface 8 to detect the user's breathing. When the user inhales, the control system controls the first solenoid valve to open and deliver oxygen to the user.

[0041] To prevent the oxygen outlet 18 from being blocked or the internal pipeline from being bent and obstructing the gas path, which could lead to excessive pressure in the pipeline and affect the breathing sensor, the oxygen injection valve seat is also equipped with a safety valve (not shown in the figure) on the gas path connected to the breathing sensor. The safety valve can be a pressure relief valve, a pressure reducing valve, or a one-way valve, etc., to release the high pressure leading to the breathing sensor and prevent damage to the breathing sensor.

[0042] To meet the dual needs of some users for oxygen generation and nebulization, and to reduce the cost of purchasing two devices at the same time, a nebulization function can be added to the oxygen generator. The nebulization valve assembly 9 can be integrated into the gas storage tank. Therefore, the gas storage tank also includes: the nebulization valve assembly 9, which is located on the outside of the oxygen injection valve assembly 6; the nebulization valve assembly 9 includes a nebulization valve seat and a second solenoid valve.

[0043] Furthermore, to facilitate assembly and save on piping connections, the atomizing valve seat in atomizing valve assembly 9 and the oxygen injection valve seat in oxygen injection valve assembly 6 are integrally formed and connected (e.g., Figure 4 (As shown).

[0044] Because the atomizing valve seat and the oxygen injection valve seat are integrally formed and connected, the third interface 6-3 and the fifth interface 9-2 can be connected in the air passage, omitting the oxygen outlet of the oxygen injection valve seat, so that oxygen is output through the air outlet of the atomizing valve seat.

[0045] The atomizing valve seat is provided with the fourth interface 9-1, the fifth interface 9-2, and the sixth interface 9-3 from right to left (e.g., ...). Figure 5 As shown in the figure, a second solenoid valve is installed on the atomizing valve seat. The airflow port of the second solenoid valve corresponds to the three ports on the atomizing valve seat. The second solenoid valve is a two-position three-way solenoid valve. When the second solenoid valve is open, the fourth port 9-1 is connected to the sixth port 9-3, and the sixth port 9-3 is connected to the air outlet on the atomizing valve seat for outputting compressed gas. When the second solenoid valve is closed, the fifth port 9-2 is connected to the sixth port 9-3 for outputting oxygen or detecting the user's breathing.

[0046] Specifically, when the first solenoid valve is open and the second solenoid valve is closed, the first and third interfaces are connected, and the fifth and sixth interfaces are connected. Since the third interface 6-3 is connected to the fifth interface 9-2, oxygen is output to the user end through the oxygen storage tank 17, the oxygen injection valve seat, the atomizing valve seat, and the oxygen concentration pipe 11 for the user to inhale oxygen.

[0047] When the first solenoid valve is closed and the second solenoid valve is open, the fourth and sixth interfaces are connected, and the oxygen injection valve seat and the atomizing valve seat are not connected, so that the high-pressure air output by the compressor 14 is delivered to the user end for atomization after passing through the atomizing valve seat and the oxygen concentration tube 11.

[0048] When the first solenoid valve is closed and the second solenoid valve is also closed, the second and third interfaces are connected, and the fifth and sixth interfaces are connected. At this time, the oxygen injection valve seat and the nebulizer valve seat are connected to detect the user's breathing status.

[0049] In this embodiment, the gas path is as follows: the gas compressed by the compressor 14 is divided into two paths through the connecting tee 15. One path is output through the atomizing valve group 9 → oxygen concentration pipe 11 → oxygen outlet 18 for users to use for atomization; the other path is output through the molecular sieve inlet valve group → molecular sieve tank 12 → pressure equalization valve → gas storage tank 17 → oxygen injection valve group 6 → atomizing valve group 9 → oxygen concentration pipe 11 → oxygen outlet 18 for users to use for oxygen inhalation.

[0050] In one embodiment, in order to facilitate the connection between the oxygen outlet 18 and the oxygen concentration pipe 11 and make the internal structure of the oxygen generator more compact, the upper end face of the atomizing valve seat is flush with the upper end face of the oxygen injection valve seat, which facilitates the setting of the connecting pipeline and is conducive to the compactness of the internal structure of the gas oxygen generator.

[0051] The gas storage tank in this embodiment is applied to an oxygen generator, and the internal structure layout of the oxygen generator is as follows: Figure 6As shown, the oxygen generator also includes a molecular sieve tank 12 and a compressor 14. A gas storage tank 17 is located on one side of the main support 13. One side of the gas storage tank 17 is separated by a horizontally arranged third partition. A molecular sieve inlet valve assembly is located above the third partition, and a fan is located below the third partition. The compressor 14 is located below the fan and the gas storage tank 17. The molecular sieve tank 12 is located on the main support 13 behind the gas storage tank. A gas inlet 4 is provided at the bottom of the gas storage tank 17. A notch is provided on the main support 13 corresponding to the gas inlet 4. The gas inlet 4 is inserted into the notch, facilitating the delivery of oxygen from the molecular sieve tank 12 to the gas storage tank 17, saving piping and making the layout more rational. To facilitate the fixing of the gas storage tank 17, a limiting block 5 is also provided at the bottom of the gas storage tank 17. A groove is provided on the main support 13 at a position corresponding to the limiting block 5. The limiting block 5 is inserted into the groove to limit the position of the gas storage tank 17.

[0052] In one embodiment, to facilitate the fan's diversion of external airflow, an air inlet is detachably provided on the oxygen concentrator's casing, located to one side of the fan. To filter the gas entering the compressor 14, a filter box 16 is provided on the bottom plate of the oxygen concentrator's casing within the air inlet. The filter box 16 has an open top, is filled with filter cotton, and has a slot on its open side wall. The open design of the filter box facilitates filter cotton replacement, and the slot on the open side wall makes it easy to retrieve the filter cotton.

[0053] The above embodiments are merely exemplary embodiments of this utility model and are not intended to limit this utility model. Those skilled in the art can make various modifications or equivalent substitutions to this utility model within its substance and protection scope, and such modifications or equivalent substitutions should also be considered to fall within the protection scope of this utility model.
