[0036] An embodiment of this application provides an oxygen generation device 100, which is applicable to various silent oxygen-using scenarios and can increase the oxygen-using load.

[0037] Referring to Figure 1 and Figure 2 As shown, the oxygen generation device 100 includes an oxygen generation device 110 and a storage device 120. The oxygen generation device 110 includes a compression assembly 111 and an adsorption assembly 112. The compression assembly 111 includes a plurality of compression cylinders 1111, and each compression cylinder 1111 has at least one input end 1112 and at least one output end 1113. The adsorption assembly 112 includes at least one adsorber 1121; the storage device 120 includes at least one first storage container 121, and the first storage container 121 is used for storing oxygen.

[0038] Among them, the compression component 111 has at least one compression cylinder 1111 for compressing air. The input end 1112 of the compression cylinder 1111 is used to absorb external air, and the output end 1113 of the compression cylinder 1111 is connected to the adsorber 1121 through a pipeline; the adsorber 1121 is used to adsorb oxygen in the compressed air and discharge the oxygen into the external environment or the input end 1112 of other compression cylinders 1111 that are not used for compressing air. And the compression cylinder 1111 that is not used for compressing air has an output end 1113 for discharging the oxygen from the adsorber 1121, and this output end 1113 is detachably connected to a first storage container 121.

[0039] It can be understood that, in combination with the accompanying drawings and common knowledge, gas can flow between the components in this application through pipelines, and the pipelines will not be described one by one here.

[0040] Exemplarily, the number of compression cylinders 1111 can be two, three, four, etc., and can be specifically set according to the required oxygen compression intensity. A single compression cylinder 1111 can be understood as a single-cylinder compressor. Of course, a multi-cylinder compressor can also be used, that is, in a compressor, there are multiple compression cylinders 1111 for multi-stage compression of oxygen. At the same time, each compression cylinder 1111 is provided with at least one input end 1112 and an output end 1113 to absorb and compress and discharge gas. The input end 1112 and the output end 1113 can each be one, two, three, four, etc., and can be specifically set according to the actual situation.

[0041] In this embodiment, the compression component 111 can adopt a double-cylinder double-piston four-in four-out compressor. During the operation process, the input end 1112 of a compression cylinder 1111 absorbs external air, and after compression, it enters the adsorber 1121 through the output end 1113. After the adsorber 1121 adsorbs the oxygen in the compressed air, it can directly supply oxygen outward through the pipeline. In the case where oxygen is not needed, the oxygen in the adsorber 1121 can be transported through the pipeline to other compression cylinders 1111 that do not perform air compression, so as to perform multi-stage compression of oxygen, and then be transported to the storage container through the output end 1113.

[0042] The adsorption component 112 is used to adsorb oxygen in the compressed air, and its quantity can be one, two, three, four, etc., and can be specifically set according to the oxygen supply demand. In this embodiment, the number of adsorption components 112 can be one. The inside of the adsorber 1121 is filled with molecular sieve material to retain oxygen inside the adsorber 1121 and discharge it to the application environment or the storage component.

[0043] Refer to together Figure 3As shown, the storage device 120 can be used to store the oxygen compressed by the compression component 111. The first storage container 121 can be provided with one, two, three, etc., which can be specifically set according to the oxygen consumption requirements. The first storage container 121 can be a gas storage tank or a gas storage box structure, and can control the entry and exit of gas through a valve. Quick plug connectors can be respectively arranged at the output end 1113 of the first storage container 121 and the compression cylinder 1111 to realize the quick disassembly and assembly of the oxygen generation device 110 and the storage device 120, improving the usage convenience.

[0044] In the related art, during the oxygen use process, only the oxygen generator can be used for real-time operation, and oxygen generation and supply are carried out simultaneously. Therefore, during the use process, the compressor will generate relatively large noise. Moreover, the oxygen supply of the oxygen generator is limited and cannot meet the scenarios with large oxygen consumption.

[0045] The oxygen generation equipment 100 provided by the present application, through the separate arrangement of the oxygen generation device 110 and the storage device 120, in the daily oxygen use scenario, the oxygen generation device 110 can be used alone, and oxygen generation and supply are carried out synchronously. The storage device 120 can also be connected to the oxygen generation device 110, and the oxygen is compressed and input into the first storage container 121 through the compression component 111. In a silent oxygen use environment such as at night, the valve of the first storage container 121 can be opened to release oxygen, without generating oxygen supply noise, providing multiple application scenarios. At the same time, the setting of multiple first storage containers 121 can effectively increase the oxygen storage capacity and meet the scenarios with large oxygen consumption.

[0046] Refer to Figure 2 As shown, in some embodiments, the oxygen generation device 110 further includes a second storage container 113. The air inlet end of the second storage container 113 is communicated with the adsorber 1121, and the exhaust end of the second storage container 113 is respectively communicated with the external environment and the input end 1112 of the compression cylinder 1111 that does not compress air.

[0047] Exemplarily, the second storage container 113 is a temporary gas storage tank. During the oxygen generation process of the adsorber 1121, the oxygen can be transported to the second storage container 113 for temporary storage and buffered when the oxygen generation amount is large. Then, the oxygen is transported to the external oxygen use environment through the second storage container 113, or transported to the compression cylinder 1111 that does not compress air, and stored in the first storage container 121 after compression.

[0048] Refer to Figure 2As shown, in some embodiments, the oxygen generation device 110 further includes a solenoid valve 115 and a low-pressure pipeline 116. One end of the low-pressure pipeline 116 is connected to the solenoid valve 115, and the other end of the low-pressure pipeline 116 away from the solenoid valve 115 communicates with the external environment. The solenoid valve 115 is respectively connected to the second storage container 113 and the input end 1112 of the compression cylinder 1111 that does not compress air.

[0049] Exemplarily, the solenoid valve 115 is provided with three connectors and automatically controls the opening and closing of each connector to realize the automatic control of the oxygen flow direction. Specifically, one connector is connected to the second storage container 113 to receive oxygen from the second storage container 113; one is connected to the low-pressure pipeline 116 and controls the opening and closing of the low-pressure pipeline 116 to realize the low-pressure oxygen supply operation of the low-pressure pipeline 116 and directly transport oxygen to the application environment; one is connected to the compression cylinder 1111 that does not compress air, and after the oxygen is transported to the compression cylinder 1111 for compression, it is input into the first storage container 121.

[0050] Refer to Figure 2 As shown, in some embodiments, the oxygen generation device 110 further includes a four-way valve 114. The four-way valve 114 has four connection ends, and at least one connection end communicates with the output end 1113 of the compression cylinder 1111 for compressing air, and at least one connection end not connected to the compression cylinder 1111 communicates with the adsorber 1121.

[0051] Exemplarily, one connection end of the four-way valve 114 is an air inlet end for receiving compressed air from the compression cylinder 1111. When multiple compression cylinders 1111 compress air, this connection end can be connected to the output ends 1113 of multiple compression cylinders 1111 through pipelines at the same time. The other connection ends are connected to the adsorber 1121 through pipelines to transport the compressed air to the adsorber 1121. Multiple connection ends can be connected to one adsorber 1121 at the same time, or can be respectively connected to different adsorbers 1121 to perform corresponding oxygen adsorption operations.

[0052] Refer to Figure 2 As shown, in some embodiments, the oxygen generation device 110 further includes an intake muffler 117. The intake muffler 117 is installed at the input end 1112 of the compression cylinder 1111 for absorbing external air. The intake muffler 117 can attenuate or reflect the noise in the input end 1112 to reduce the noise during the operation of the compression assembly 111.

[0053] Refer to Figure 4 and Figure 5 As shown, in some embodiments, the oxygen generation device 110 further includes a cooling fan 119. The cooling fan 119 is arranged at one end of the compression cylinder 1111.

[0054] Exemplarily, when the cooling fan 119 is in the powered-on state, corresponding gas exchange operations are performed through the fan blades to discharge the heat generated by the compression assembly 111 during operation, reduce the risk of device loss, and extend the service life.

[0055] It can be understood that in some other embodiments, a liquid-cooled cooling fan 119 can also be used in the oxygen generation device 110. By replacing the cooling fan 119 with a liquid-cooled radiator, the heat dissipation function of the compression assembly 111 can be satisfied.

[0056] Refer to Figure 7 As shown, in some embodiments, the oxygen generation device 110 further includes a housing 118, and the housing 118 is provided with a hollow hole 1181 for gas exchange.

[0057] Exemplarily, the housing 118 can be a box structure assembled by metal plates. Through the cooperation of the hollow hole 1181 and the cooling fan 119, the hot air inside the housing 118 is discharged for gas exchange cooling. In some other embodiments, relevant holes can also be opened in the housing 118, and the heat dissipation function can be achieved by installing a grid plate at the hole positions.

[0058] It can be understood that a similar housing 118 structure can also be set for the storage component to assemble and protect the plurality of first storage containers 121. Pulleys can be provided at the bottom of the housing 118 to facilitate the overall movement of the device.

[0059] Refer to Figure 2 As shown, in some embodiments, the adsorption assembly 112 further includes at least one exhaust valve 1122, and each exhaust valve 1122 is communicated with the adsorber 1121 and is used for discharging nitrogen in the compressed air.

[0060] Exemplarily, when the oxygen in the compressed air is adsorbed by the molecular sieve in the adsorber 1121, a large amount of nitrogen is separated out and discharged through the exhaust valve 1122, so that the oxygen is adsorbed in the adsorber 1121. A corresponding muffler can be provided for the exhaust valve 1122 to reduce the exhaust noise during the operation of the exhaust valve 1122.

[0061] Refer to Figure 3 As shown, in some embodiments, the storage device 120 includes a plurality of first storage containers 121 and a safety valve 122. Each first storage container 121 is connected in series through pipelines, and the safety valve 122 is installed on the pipeline.

[0062] Exemplarily, in this embodiment, the number of the first storage containers 121 may be three. The three first storage containers 121 are sequentially connected by pipelines. A quick connector is provided on one of the first storage containers 121 closest to the oxygen generation device 110 for connection to the oxygen generation device 110. The safety valve 122 is normally closed under the action of an external force. When the oxygen pressure in the pipeline rises above the specified value, it prevents the medium pressure in the pipeline from exceeding the specified value by discharging gas outward. During the operation process, the compressed oxygen is transported by the compression assembly 111 and sequentially enters each first storage container 121. The safety valve 122 installed on the pipeline controls the internal gas pressure of the pipeline and reduces safety accidents.

[0063] Refer to Figure 3 As shown, in some embodiments, the storage device 120 further includes a pressure relief valve 123. The pressure relief valve 123 is connected to one of the first storage containers 121 farthest from the oxygen generation device 110.

[0064] Exemplarily, the pressure relief valve 123 can be used in cooperation with a pressure sensor or a pressure gauge. The pressure sensor or the pressure gauge is used to obtain the gas pressure in the pipeline, and the pressure relief valve 123 performs corresponding pressure relief operations. The pressure relief valve 123 is preset with a corresponding pressure threshold. When the pressure in the container exceeds the set pressure of the pressure relief valve 123, it automatically opens for pressure relief to ensure that the oxygen pressure in the container is below the set pressure, protecting the equipment and pipelines and preventing accidents.

[0065] Refer to Figure 4 、 Figure 5 and Figure 6 As shown, in some other embodiments, the compression assembly 111 includes two double-cylinder double-piston four-in-four-out compressors, that is, the compression assembly 111 has four compression cylinders 1111. There are two adsorption assemblies 112, and each adsorption assembly 112 includes two adsorbers 1121. All the adsorbers 1121 share the same nitrogen exhaust muffler. The exhaust end of the second storage container 113 is connected to the compressor that does not perform air compression.

[0066] During the operation process, two compression cylinders 1111 of one compressor perform air compression simultaneously. An intake muffler 117 is provided at the input end 1112 of each compression cylinder 1111 of this compressor, and the output ends are connected by pipelines and converge on the same output pipeline to output the compressed air to the four-way valve 114. The two connection ends of the four-way valve 114 respectively transport the compressed air to the two adsorbers 1121 through different pipelines to improve the oxygen generation rate. The oxygen adsorbed inside the two adsorbers 1121 is transported to the second storage container 113 through the same pipeline, and then is transported to the solenoid valve 115 or the compressor that does not perform air compression through the second storage container 113.

[0067] When performing low-pressure oxygen supply, the low-pressure pipeline 116 can be opened through the solenoid valve 115 to achieve the low-pressure oxygen supply operation of the low-pressure pipeline 116, and directly supply oxygen to the application environment; while during non-oxygen supply operations, the low-pressure pipeline 116 can be closed, so that the compressed oxygen enters the compressor without air compression. The second storage container 113 is connected to the input end 1112 of a compression cylinder 1111 of the compressor through a pipeline. After being compressed once by the compression cylinder 1111, it enters the input end 1112 of another compression cylinder 1111 of the same compressor through the output end 1113 for secondary compression of oxygen, and finally the oxygen is input into the first storage container 121 from the output end 1113. Of course, when the oxygen production rate is satisfied, the low-pressure oxygen supply and the oxygen compression and storage operations can also be carried out simultaneously.

[0068] It can be understood that the oxygen production equipment 100 provided in this application can also include solutions with three, four, etc. compressors, which can be specifically set according to the demand for oxygen production amount, and the working principle can be the same as that of the above embodiments, and will not be listed one by one here.

[0069] The technical features of the above-described embodiments can be combined arbitrarily. For the sake of brevity of description, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, it should be considered as the scope described in this specification.

[0070] The above-described embodiments only represent several implementation manners of this application, and their descriptions are relatively specific and detailed, but they should not be construed as a limitation to the scope of the patent application. It should be noted that for those of ordinary skill in the art, without departing from the concept of this application, several modifications and improvements can still be made, and these all belong to the protection scope of this application. Therefore, the protection scope of the patent of this application shall be subject to the appended claims.
