Description

[0001] This utility model relates to the field of oxygen generation equipment technology, and in particular to an oxygen generation module. Background Technology

[0002] In existing technologies, some oxygen generating modules effectively separate nitrogen and oxygen in the air using a dual-tower (Tower A and Tower B) molecular sieve design, thereby obtaining a gas with a high concentration of oxygen. However, after researching oxygen generating modules on the market, the inventors found that these modules have separate Tower A, Tower B, and control valves, and use numerous pipes to connect them. Therefore, these commercially available oxygen generating modules have the following problems: 1. They occupy a large amount of space; 2. The complex layout of multiple pipe connections results in high maintenance costs. Utility Model Content

[0003] The present invention aims to solve at least one of the technical problems existing in the prior art. To this end, the present invention proposes an oxygen generation module.

[0004] An oxygen-generating module according to an embodiment of the present invention includes a housing and a first control valve. The housing has a first tower cavity, a second tower cavity, a first gas cavity, a second gas cavity, a first channel, and a second channel. The first channel connects the first tower cavity and the first gas cavity, and the second channel connects the second tower cavity and the first gas cavity. The housing has a first air port, a second air port, a third air port, and a fourth air port respectively connected to the first tower cavity, the second tower cavity, the first gas cavity, and the second gas cavity. The housing also has a fifth air port connecting to the outside and the second gas cavity. The first tower cavity and the second tower cavity... All are used for placing molecular sieve components. The first control valve is located in the housing. The first gas port, the second gas port, and the fourth gas port are all directly connected to the first control valve. The first control valve has an air inlet channel. The first control valve can switch to a first state or a second state. When the first control valve is in the first state, the first control valve controls the connection between the air inlet channel and the first gas port, and the connection between the second gas port and the fourth gas port. When the first control valve is in the second state, the first control valve controls the connection between the air inlet channel and the second gas port, and the connection between the first gas port and the fourth gas port.

[0005] An oxygen-generating module according to an embodiment of the present invention has at least the following features:

[0006] Beneficial effects:

[0007] When the first control valve is in its first state, after the gas enters the inlet channel, the gas has two flow paths in the oxygen generation module. In one flow path, the gas flows sequentially through the first gas port, the first tower cavity, the first channel, and the first gas chamber before exiting through the third gas port. In the other flow path, the gas flows sequentially through the first gas port, the first tower cavity, the first channel, the first gas chamber, the second channel, the second tower cavity, the second gas port, the fourth gas port, and the second gas chamber before exiting through the fifth gas port. Therefore, when the gas is compressed air, and both the first and second tower cavities contain molecular sieve components, on the one hand, the compressed air is adsorbed with impurities such as nitrogen in the first tower cavity of one of the aforementioned flow paths to obtain gas with a high concentration of oxygen before exiting through the third gas port; on the other hand, the compressed air is adsorbed with impurities such as nitrogen in the first tower cavity of the other flow path to obtain gas with a high concentration of oxygen. This high-concentration oxygen gas then enters the second tower cavity to flush the saturated molecular sieve components, restoring the saturated components, and causing the flushed nitrogen to flow sequentially through the second gas port, the fourth gas port, and the second gas chamber before exiting through the fifth gas port.

[0008] When the first control valve is in its second state, after the gas enters the inlet channel, the gas has two flow paths in the oxygen generation module. In one flow path, the gas flows sequentially through the second gas port, the second tower cavity, the second channel, and the first gas cavity before exiting through the third gas port. In the other flow path, the gas flows sequentially through the second gas port, the second tower cavity, the second channel, the first gas cavity, the first channel, the first tower cavity, the first gas port, the fourth gas port, and the second gas cavity before exiting through the fifth gas port. Therefore, when the gas is compressed air, and both the first and second tower cavities contain molecular sieve components, on the one hand, the compressed air is adsorbed with impurities such as nitrogen in the second tower cavity of one of the aforementioned flow paths to obtain gas with a high concentration of oxygen before exiting through the third gas port; on the other hand, the compressed air is adsorbed with impurities such as nitrogen in the second tower cavity of the other flow path to obtain gas with a high concentration of oxygen. This high-concentration oxygen gas then enters the first tower cavity to flush the saturated molecular sieve components, restoring the saturated components, and causing the flushed nitrogen to flow sequentially through the first gas port, the fourth gas port, and the second gas cavity before exiting through the fifth gas port.

[0009] With the above structure, on the one hand, the oxygen generating module of this application arranges the A tower and B tower (i.e., the first tower cavity and the second tower cavity structure) in a container to reduce the space occupied; on the other hand, the oxygen generating module of this application realizes the connection between the first tower cavity, the second tower cavity and the first control valve through the gas cavity, channel and gas port structure on the container shell. Therefore, the oxygen generating module of this application does not need to adopt the pipe connection layout, so as to reduce the cost of later maintenance.

The top inlet of the guide channel is arranged opposite to the fourth air port, and the bottom outlet of the guide channel is arranged opposite to the fifth air port. Gas entering the second air chamber from the fourth air port can pass through the guide channel and then be discharged from the fifth air port.

[0012] According to some embodiments of the present invention, the flow guiding channel is provided with at least two partitions, which are arranged sequentially in the vertical direction to divide the flow guiding channel into at least three channel segments arranged sequentially in the vertical direction. The uppermost channel segment is connected to the top inlet of the flow guiding channel, and the lowermost channel segment is connected to the bottom outlet of the flow guiding channel. The partitions are provided with openings connecting two adjacent channel segments, and the two adjacent openings are arranged left and right.

For example, they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to a fixed connection, a detachable connection, or an integral molding; they can refer to a mechanical connection; they can refer to the internal connection of two components or the interaction between two components. Those skilled in the art can reasonably determine the specific meaning of the above terms in this utility model in conjunction with the specific content of the technical solution.

[0036] Reference Figures 1 to 5 An embodiment of this utility model provides an oxygen generating module, which includes a housing 100 and a first control valve 200.

[0037] The housing 100 is provided with a first tower cavity S1, a second tower cavity S2, a first gas cavity S3, a second gas cavity S4, a first channel 131, and a second channel 132. The first channel 131 connects the first tower cavity S1 and the first gas cavity S3, and the second channel 132 connects the second tower cavity S2 and the first gas cavity S3. The housing 100 is provided with a first gas port 121, a second gas port 122, a third gas port 123, and a fourth gas port 124 respectively connected to the first tower cavity S1, the second tower cavity S2, the first gas cavity S3, and the second gas cavity S4. The housing 100 is provided with a fifth gas port 133 connecting to the outside and the second gas cavity S4. Both the first tower cavity S1 and the second tower cavity S2 are used for placing molecular sieve components. The first control valve 200 is located in the housing 100. The first air port 121, the second air port 122, and the fourth air port 124 are all directly connected to the first control valve 200. The first control valve 200 is provided with an air intake channel 210. The first control valve 200 can be switched to a first state or a second state. When the first control valve 200 is in the first state, the first control valve 200 controls the connection between the air intake channel 210 and the first air port 121, and the connection between the second air port 122 and the fourth air port 124. When the first control valve 200 is in the second state, the first control valve 200 controls the connection between the air intake channel 210 and the second air port 122, and the connection between the first air port 121 and the fourth air port 124.

[0038] Understandably, the first control valve 200 is configured as a solenoid valve; the molecular sieve assembly includes a molecular sieve, non-woven fabric, and a porous circular sieve plate.

[0039] When the first control valve 200 is in the first state, after the gas is input into the inlet channel 210, the gas has two flow paths in the oxygen generation module. One flow path is that the gas flows sequentially through the first gas port 121, the first tower cavity S1, the first channel 131 and the first gas chamber S3 and then exits from the third gas port 123. The other flow path is that the gas flows sequentially through the first gas port 121, the first tower cavity S1, the first channel 131, the first gas chamber S3, the second channel 132, the second tower cavity S2, the second gas port 122, the fourth gas port 124 and the second gas chamber S4 and then exits from the fifth gas port 133. Therefore, when the gas is compressed air and both the first tower cavity S1 and the second tower cavity S2 are equipped with molecular sieve components, on the one hand, the compressed air is adsorbed with impurities such as nitrogen in the first tower cavity S1 of one of the above-mentioned flow paths to obtain a gas with a high concentration of oxygen and then discharged from the third gas port 123; on the other hand, the compressed air is adsorbed with impurities such as nitrogen in the first tower cavity S1 of the other flow path to obtain a gas with a high concentration of oxygen. The gas with a high concentration of oxygen enters the second tower cavity S2 to flush the saturated molecular sieve components inside, so that the saturated molecular sieve components are reduced, and the nitrogen that is flushed out flows sequentially through the second gas port 122, the fourth gas port 124 and the second gas cavity S4 and is discharged from the fifth gas port 133.

[0040] It is understandable that during the above process, while the molecular sieve components in the first tower cavity S1 are performing adsorption and impurity removal, the molecular sieve components in the second tower cavity S2 are performing regeneration and reduction.

[0041] When the first control valve 200 is in the second state, after the gas is input into the inlet channel 210, the gas has two flow paths in the oxygen generation module. One flow path is that the gas flows sequentially through the second gas port 122, the second tower cavity S2, the second channel 132 and the first gas cavity S3 and then exits from the third gas port 123. The other flow path is that the gas flows sequentially through the second gas port 122, the second tower cavity S2, the second channel 132, the first gas cavity S3, the first channel 131, the first tower cavity S1, the first gas port 121, the fourth gas port 124 and the second gas cavity S4 and then exits from the fifth gas port 133. Therefore, when the gas is compressed air and both the first tower cavity S1 and the second tower cavity S2 contain molecular sieve components, on the one hand, the compressed air is adsorbed with impurities such as nitrogen in the second tower cavity S2 of one of the above-mentioned flow paths to obtain a gas with a high concentration of oxygen and then discharged from the third gas port 123; on the other hand, the compressed air is adsorbed with impurities such as nitrogen in the second tower cavity S2 of the other flow path to obtain a gas with a high concentration of oxygen. The gas with a high concentration of oxygen enters the first tower cavity S1 to flush the saturated molecular sieve components inside, so that the saturated molecular sieve components are restored, and the nitrogen that is flushed out flows sequentially through the first gas port 121, the fourth gas port 124 and the second gas cavity S4 and is discharged from the fifth gas port 133.

[0042] It is understandable that during the above process, while the molecular sieve components in the second tower cavity S2 are performing adsorption and impurity removal, the molecular sieve components in the first tower cavity S1 are performing regeneration and reduction.

[0043] Understandably, with the operation of the first control valve 200, the molecular sieve components in the first tower chamber S1 and the second tower chamber S2 can work alternately to ensure that the oxygen generation module can achieve continuous oxygen generation.

[0044] With the above structure, on the one hand, the oxygen generating module of this application arranges the A tower and B tower (i.e., the first tower cavity S1 and the second tower cavity S2 structure) in a container to reduce the space occupied; on the other hand, the oxygen generating module of this application realizes the connection between the first tower cavity S1, the second tower cavity S2 and the first control valve 200 through the gas cavity, channel and gas port structure on the container shell. Therefore, the oxygen generating module of this application does not need to adopt the pipe connection layout, so as to reduce the cost of later maintenance.

[0045] In this embodiment, refer to Figures 1 to 5The container 100 includes a shell component 110, a top cover component 120, and a bottom cover component 130. The shell component 110 has four hollow cavities 111. The top cover component 120 and the bottom cover component 130 are detachably disposed on the top and bottom of the shell component 110, respectively. The top cover component 120 and the bottom cover component 130 respectively close two openings of the cavities 111 to form the first tower cavity S1, the second tower cavity S2, the first air cavity S3, and the second air cavity S4. The top cover component 120 has the first air port 121, the second air port 122, the third air port 123, and the fourth air port 124. A first control valve 200 is disposed on the top cover component 120. The bottom cover component 130 has the first channel 131, the second channel 132, and the fifth air port 133.

[0046] It is understood that the top cover 120 is provided with the first air port 121, the second air port 122, the third air port 123 and the fourth air port 124, and the first control valve 200 is provided on the top cover 120, that is, the first air port 121, the second air port 122, the third air port 123 and the fourth air port 124 are all provided on the top of the container 100; the bottom cover 130 is provided with the first channel 131, the second channel 132 and the fifth air port 133, that is, the first channel 131, the second channel 132 and the fifth air port 133 are all provided on the bottom of the container 100.

[0047] With the above structure, both the top cover 120 and the bottom cover 130 are detachably connected to the housing 110, which facilitates the maintenance of the oxygen generation module in the later stages.

[0048] In this embodiment, both the top cover 120 and the bottom cover 130 are detachably connected to the housing 110 by screws, as detailed below. Figure 3 and Figure 4 As shown.

[0049] To enhance the tightness of the connection between the top cover 120 and the housing 110, and to further enhance the tightness of the connection between the bottom cover 130 and the housing 110, refer to... Figures 3 to 5 The top cover 120 and the bottom cover 130 are respectively provided with a first groove 125 and a second groove 134. The top cover 120 is fitted onto the top of the housing 110 through the first groove 125, and the bottom cover 130 is fitted onto the bottom of the housing 110 through the second groove 134.

[0050] In this embodiment, refer to Figures 3 to 5 Both the first groove 125 and the second groove 134 are provided with sealing elements 300, which abut against the housing 110. The sealing element 300 is a sealing silicone gasket.

[0051] With the above structure, the seal 300 abuts against the housing 110, thereby improving the connection sealing between the top cover 120 and the housing 110, and improving the connection sealing between the bottom cover 130 and the housing 110.

[0052] In this embodiment, refer to Figure 1 The container 100 is equipped with a second control valve 500, and a third air port 123 is directly connected to the second control valve 500. The second control valve 500 is equipped with an air outlet channel 510. The second control valve 500 can control the connection between the air outlet channel 510 and the third air port 123, or control the disconnection between the air outlet channel 510 and the third air port 123. The second control valve 500 is configured as a solenoid valve.

[0053] With the above structure, the second control valve 500 can cut off or open the third gas port 123, so as to control the stop, or control the opening, or control the timed opening and closing of the gas with high oxygen concentration output from the gas outlet channel 510.

[0054] In this embodiment, the second control valve 500 is provided with an adjusting element, which can adjust the flow rate of the air outlet channel 510.

[0055] In this embodiment, refer to Figure 4 The second air chamber S4 is provided with a guide member 400 located between the fourth air port 124 and the fifth air port 133.

The top inlet 411 of the guide channel 410 is arranged opposite to the fourth air port 124, and the bottom outlet 412 of the guide channel 410 is arranged opposite to the fifth air port 133. The gas entering the second air chamber S4 from the fourth air port 124 can pass through the guide channel 410 and be discharged from the fifth air port 133.

[0056] With the above structure, the gas entering the second gas chamber S4 from the fourth gas port 124 can flow in a directional manner toward the fifth gas port 133 through the guide channel 410.

[0057] In this embodiment, refer to Figure 4 and Figure 5 The flow channel 410 is provided with thirteen partitions 600, which are arranged in sequence along the vertical direction to divide the flow channel 410 into fourteen channel segments S5 arranged in sequence along the vertical direction. The uppermost channel segment S5 is connected to the top inlet 411 of the flow channel 410, and the lowermost channel segment S5 is connected to the bottom outlet 412 of the flow channel 410. The partition 600 is provided with an opening 610 connecting two adjacent channel segments S5, and the two adjacent openings 610 are arranged on the left and right.

[0058] With the above structure, when the gas passes through the guide channel 410, it can pass through thirteen ports 610 in sequence to slow down the flow rate and reduce the noise generated.

[0059] In some embodiments, the partition 600 may be configured to have ten, fourteen, or other partitions.

[0060] To further reduce the generated noise, in this embodiment, a sound-absorbing and breathable component is provided inside the flow channel 410. This sound-absorbing and breathable component can be made of cotton or similar materials.
