[0061] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this utility model, and should not be construed as limiting this utility model.

[0062] The following is for reference. Figures 1-10 Describes an oxygen generating device 100 according to an embodiment of the present invention.

[0063] refer to Figures 1-2 According to the first aspect of the present invention, an oxygen generating device 100 includes: a device housing 10, a separation membrane assembly 20, and a pump 30.

[0064] The device housing 10 has a receiving cavity 11, and the device housing 10 has an air inlet structure 12 and an air outlet structure 13 communicating with the receiving cavity 11. The separation membrane assembly 20 and the pump 30 are both disposed in the receiving cavity 11. The separation membrane assembly 20 has an oxygen enrichment chamber, which is used to enrich oxygen in the air into the oxygen enrichment chamber. The inlet 31 of the pump 30 is connected to the separation membrane assembly 20 and communicates with the oxygen enrichment chamber. The outlet 32 ​​of the pump 30 is connected to an oxygen output pipeline 40.

[0065] For example, pump 30 can be a vacuum pump or an air compressor.

[0066] For example, when the oxygen generator 100 is working, air enters the receiving cavity 11 of the device housing 10 from the air intake structure 12 on the device housing 10. The pump 30 starts working and generates negative pressure in the oxygen-enriching cavity. The air flows through the separation membrane assembly 20. Taking advantage of the different permeation rates of different gases in the air through the separation membrane in the separation membrane assembly 20, since the migration rate of oxygen molecules in the separation membrane is faster than that of other gases in the air, such as nitrogen molecules, oxygen in the air can pass through the separation membrane and be enriched in the oxygen-enriching cavity of the separation membrane assembly 20, thereby enriching the oxygen in the air into the oxygen-enriching cavity.

[0067] The oxygen enriched in the oxygen-enriched chamber is driven by the pump 30 and enters the pump 30 from the inlet 31 and exits from the outlet 32. Since the outlet 32 ​​of the pump 30 is connected to the oxygen output pipeline 40, the oxygen discharged from the outlet 32 ​​of the pump 30 can be output to a designated area or location through the oxygen output pipeline 40. For example, it can be output to the room or a designated area or location inside the room through the oxygen output pipeline 40, thereby increasing the oxygen concentration in the indoor air and improving the indoor air quality.

[0068] According to some embodiments of this utility model, the thickness direction of the separation membrane assembly 20 is parallel to the first direction, and the pump 30 and the separation membrane assembly 20 are arranged along the second direction, which intersects the first direction. By making the thickness direction of the separation membrane assembly 20 parallel to the first direction, the installation difficulty of the separation membrane assembly 20 can be reduced, the stability of the installation of the separation membrane assembly 20 can be improved, oxygen in the air can be more stably enriched into the oxygen-enriching chamber, and the space in the receiving cavity 11 can be fully utilized, reducing the space occupied and wasted by the separation membrane assembly 20 in the first direction. By arranging the pump 30 and the separation membrane assembly 20 along the second direction, the internal structure of the oxygen generator 100 is arranged more compactly, improving the space utilization rate in the receiving cavity 11, thereby making the overall volume of the oxygen generator 100 smaller.

[0069] Compared to the larger oxygen generator 100, the smaller oxygen generator 100 is easier to install and store. For example, it is easier to store during transportation and storage. Furthermore, the smaller oxygen generator 100 occupies less space; it can be installed indoors, reducing indoor space usage, or outdoors, reducing outdoor space usage.

[0070] According to some embodiments of the present invention, the oxygen generating device 100, by making the thickness direction of the separation membrane assembly 20 parallel to the first direction and arranging the pump 30 and the separation membrane assembly 20 along the second direction, makes the thickness direction of the separation membrane assembly 20 different from the arrangement direction of the pump 30 and the separation membrane assembly 20. This allows the separation membrane assembly 20 to be placed flat relative to the device housing 10, making the installation of the separation membrane assembly 20 more stable and making full use of the space in the receiving cavity 11. This reduces the space occupied by the separation membrane assembly 20 in the first direction, making the internal structure of the oxygen generating device 100 more compact and improving the space utilization rate in the receiving cavity 11. Thus, under the condition of a certain oxygen generating power, it is beneficial to reduce the volume of the oxygen generating device 100, reduce the space occupied by the oxygen generating device 100, and facilitate the installation and storage of the oxygen generating device 100.

[0071] refer to Figure 5According to some embodiments of the present invention, the dimension of pump 30 along the first direction is smaller than the dimension of pump 30 along the second direction and smaller than the dimension of pump 30 along the third direction, and the first direction, the second direction and the third direction intersect each other.

[0072] Among them, the dimension of pump 30 along the first direction is the dimension of the longest part of pump 30 in the first direction; the dimension of pump 30 along the second direction is the dimension of the longest part of pump 30 in the second direction; and the dimension of pump 30 along the third direction is the dimension of the longest part of pump 30 in the third direction.

[0073] By making the dimension of pump 30 along the first direction smaller than that along the second direction and smaller than that along the third direction, the dimension of pump 30 in the first direction is relatively small. Since the thickness direction of the separation membrane assembly 20 is consistent with the first direction, the space occupied by the separation membrane assembly 20 in the first direction is small. By making the dimension of pump 30 in the first direction also small, the difference in space occupied by separation membrane assembly 20 and pump 30 in the first direction is small, reducing the space occupied by pump 30 in the first direction. This makes the internal structure of oxygen generator 100 more compact, improves the space utilization rate in the housing cavity 11, and makes the overall volume of oxygen generator 100 smaller, which facilitates the installation and storage of oxygen generator 100.

[0074] refer to Figure 1 According to some embodiments of this utility model, the dimension of the separation membrane assembly 20 along the first direction is smaller than the dimension of the separation membrane assembly 20 along the second direction and smaller than the dimension of the separation membrane assembly 20 along the third direction. By making the dimension of the separation membrane assembly 20 along the first direction smaller than the dimension of the separation membrane assembly 20 along the second direction and smaller than the dimension of the separation membrane assembly 20 along the third direction, the dimension of the separation membrane assembly 20 in the first direction is relatively small. Since the thickness direction of the separation membrane assembly 20 is consistent with the first direction, the space occupied by the separation membrane assembly 20 in the first direction is smaller, thereby reducing the difference in the size of the space occupied by the separation membrane assembly 20 in the first direction, reducing the space occupied by the separation membrane assembly 20 in the first direction, making the internal structure of the oxygen generator 100 more compact, improving the space utilization rate in the receiving cavity 11, making the overall volume of the oxygen generator 100 smaller, and facilitating the installation and storage of the oxygen generator 100.

[0075] refer to Figure 1According to some embodiments of this utility model, the absolute value of the difference between the dimension of the separation membrane assembly 20 and the dimension of the pump 30 in the first direction is a first difference, and the ratio of the first difference to the dimension of the separation membrane assembly 20 or the pump 30 in the first direction is less than 0.1. For example, the ratio of the first difference to the dimension of the separation membrane assembly 20 or the pump 30 in the first direction is 0.08, 0.06, 0.05, 0.04, 0.03, 0.02, 0.01, etc. This arrangement allows the dimension of the separation membrane assembly 20 in the first direction to be approximately equivalent to the dimension of the pump 30 in the first direction, making full use of the space of the device housing 10 along the first direction, reducing the waste of space in the device housing 10 along the first direction, and making the components inside the device housing 10 compactly arranged.

[0076] refer to Figure 1 According to some embodiments of this utility model, the oxygen output pipeline 40 includes a silencer 43, which is disposed inside the device housing 10 and located on the side of the separation membrane assembly 20 close to the pump 30 along the second direction. By including the silencer 43 in the oxygen output pipeline 40, the oxygen output from the pump 30 is silenced and its noise reduced by passing through the silencer 43, thereby reducing the noise of the oxygen output from the pump 30. The noise-reduced oxygen is then delivered to the room, thus reducing the noise when the oxygen is delivered to the room.

[0077] For example, the receiving cavity 11 inside the device housing 10 can be divided into a first receiving area 111 and a second receiving area 112 along the second direction. The separation membrane assembly 20 is located in the first receiving area 111, and the pump 30 is located in the second receiving area 112. By placing the silencer 43 inside the device housing 10 and on the side of the separation membrane assembly 20 closer to the pump 30 along the second direction, that is, by placing both the pump 30 and the silencer 43 in the second receiving area 112, the space in the second receiving area 112 can be effectively utilized. In this way, the separation membrane assembly 20 can make full use of the space in the first receiving area 111, which is conducive to increasing the area of ​​the separation membrane assembly 20 and improving the working efficiency of the separation membrane assembly 20 in separating oxygen.

[0078] refer to Figure 1 According to some embodiments of the present invention, the muffler 43 extends along the second direction. By extending the muffler 43 along the second direction, the space of the pump 30 along the third direction can be fully utilized, making the arrangement of the pump 30 and the muffler 43 within the device housing 10 more compact and further improving the space utilization rate within the receiving cavity 11.

[0079] refer to Figure 6According to some embodiments of this utility model, the dimension of the muffler 43 along the first direction is smaller than the dimension of the muffler 43 along the second direction. By making the dimension of the muffler 43 along the first direction smaller than the dimension of the muffler 43 along the second direction, the thickness direction of the muffler 43 is parallel to the first direction and the length direction of the muffler 43 is arranged along the second direction. This allows the muffler 43 to be placed flat relative to the device housing 10, making the installation of the muffler 43 more stable and making full use of the space in the receiving cavity 11. This reduces the space occupied by the muffler 43 in the first direction, making the internal structure of the oxygen generating device 100 more compact and improving the space utilization rate in the receiving cavity 11. Thus, under the condition that the oxygen generating power of the oxygen generating device 100 is constant, it is beneficial to reduce the volume of the oxygen generating device 100.

[0080] refer to Figure 1 According to some embodiments of this utility model, the device housing 10 has a rectangular parallelepiped shape.

The dimension of the device housing 10 in the third direction is smaller than the dimension of the device housing 10 in the second direction. The first direction, the second direction, and the third direction intersect each other. By arranging the separation membrane assembly 20 and the pump 30 within the device housing 10 along the second direction, the larger space within the device housing 10 along the second direction can be fully utilized.

[0081] refer to Figure 1 According to some embodiments of this utility model, the dimension of pump 30 along the first direction is smaller than the dimension of pump 30 along the second direction and smaller than the dimension of pump 30 along the third direction, and the first direction, the second direction, and the third direction intersect each other. By making the dimension of pump 30 along the first direction smaller than the dimension of pump 30 along the second direction and smaller than the dimension of pump 30 along the third direction, the dimension of pump 30 in the first direction can be made smaller. This can match the space size of device housing 10 along the first direction, make full use of the space of device housing 10 along the first direction, make the components inside device housing 10 compact, and reduce space waste.

By making the dimension of the separation membrane assembly 20 along the first direction smaller than the dimension of the separation membrane assembly 20 along the second direction and smaller than the dimension of the separation membrane assembly 20 along the third direction, the dimension of the separation membrane assembly 20 in the first direction can be made smaller. This can match the space size of the device housing 10 along the first direction, making full use of the space of the device housing 10 along the first direction, so that the components inside the device housing 10 are arranged compactly and space waste is reduced.

[0083] According to some embodiments of the present invention, the pump 30 is detachably connected to the device housing 10.

[0084] For example, the pump 30 can be connected to the device housing 10 by means of screws, clips, etc.

[0085] The pump 30 is detachably connected to the device housing 10, allowing the pump 30 to be installed on the device housing 10 and removed from the device housing 10, facilitating the replacement and maintenance of the pump 30.

[0086] refer to Figure 5 According to some embodiments of the present invention, the outer peripheral wall of the pump 30 is provided with a plurality of pump legs 33, which are arranged at intervals along the circumference of the pump 30, and the pump legs 33 are connected to the device housing 10.

[0087] For example, the pump support 33 can be connected to the device housing 10 by means of screws, clips, etc.

[0088] By providing multiple pump support feet 33 on the outer peripheral wall of the pump 30 and connecting them to the device housing 10, the stability of the connection between the pump 30 and the device housing 10 can be enhanced, and the pump 30 is less likely to deviate from its original installation position when it is in operation.

[0089] refer to Figure 5 According to some embodiments of the present invention, both the inlet 31 and the outlet 32 ​​are located on the outer periphery of the pump 30, and the outer periphery direction of the pump 30 is perpendicular to the first direction.

[0090] For example, inlet 31 and outlet 32 ​​can be located on the same side of the outer periphery of pump 30, or they can be located on different sides of the outer periphery of pump 30.

[0091] By placing both the inlet 31 and the outlet 32 ​​on the outer periphery of the pump 30, when the inlet 31 and the outlet 32 ​​of the pump 30 are connected to the connecting pipe, the space on the outer periphery of the pump 30 can be fully utilized to arrange the pipeline. This fully utilizes the space on the outer periphery of the pump 30, reduces the space occupied by the pump 30 in the first direction, and thus improves the space utilization rate in the accommodating cavity 11. Under the condition that the oxygen generating power of the oxygen generating device 100 is constant, it is beneficial to reduce the length of the oxygen generating device 100 in the first direction, so as to reduce the volume of the oxygen generating device 100.

[0092] refer to Figure 5 According to some embodiments of the present invention, at least one of the inlet 31 and the outlet 32 ​​is located on the side of the pump 30 close to the separation membrane assembly 20 along the second direction.

[0093] For example, at least one of the inlet 31 and the outlet 32 ​​is located on the side of the pump 30 close to the separation membrane assembly 20 along the second direction. This could mean that the inlet 31 is located on the side of the pump 30 close to the separation membrane assembly 20 along the second direction, or that the outlet 32 ​​is located on the side of the pump 30 close to the separation membrane assembly 20 along the second direction, or that both the inlet 31 and the outlet 32 ​​are located on the side of the pump 30 close to the separation membrane assembly 20 along the second direction.

[0094] By placing at least one of the inlet 31 and outlet 32 ​​on the side of the pump 30 close to the separation membrane assembly 20 along the second direction, the space between the pump 30 and the separation membrane assembly 20 can be fully utilized, making the internal structure of the oxygen generator 100 more compact and improving the space utilization rate in the receiving cavity 11. Thus, under the condition that the oxygen generator 100 has a certain oxygen generation power, it is beneficial to reduce the volume of the oxygen generator 100.

[0095] refer to Figure 5 According to some embodiments of the present invention, the inlet 31 and the outlet 32 ​​are both located on the side of the pump 30 close to the separation membrane assembly 20 along the second direction, and the inlet 31 and the outlet 32 ​​are arranged along the first direction.

[0096] For example, when the first direction is up and down, the outlet 32 ​​can be located above the inlet 31.

[0097] By placing both inlet 31 and outlet 32 ​​on the side of pump 30 closer to the separation membrane assembly 20 along the second direction, the connection distance between inlet 31 and separation membrane assembly 20 is reduced, facilitating the connection between inlet 31 and separation membrane assembly 20. This helps to shorten the length of the connecting pipeline between inlet 31 and separation membrane assembly 20 of pump 30, and also makes the arrangement between inlet 31 and outlet 32 ​​more compact, improving the space utilization rate within the accommodating cavity 11. Thus, under the condition that the oxygen generating power of oxygen generating device 100 is constant, it is beneficial to reduce the volume of oxygen generating device 100.

[0098] refer to Figure 5 According to some embodiments of the present invention, the outer peripheral wall of the pump 30 is provided with a plurality of pump legs 33, which are arranged at intervals along the circumference of the pump 30 and are connected to the device housing 10. The plurality of pump legs 33 include a first pump leg 331 and a second pump leg 332, which are located on the side of the pump 30 near the separation membrane assembly 20. The first pump leg 331 and the second pump leg 332 are arranged at intervals along a third direction. In the third direction, the inlet 31 and the outlet 32 ​​are located between the first pump leg 331 and the second pump leg 332. The first direction, the second direction, and the third direction intersect each other.

[0099] For example, the first direction, the second direction, and the third direction are perpendicular to each other. The first direction can be referred to as the e1 direction in the attached figure, the second direction can be referred to as the e2 direction in the attached figure, and the third direction can be referred to as the e3 direction in the attached figure.

[0100] By placing the first pump support 331 and the second pump support 332 on the side of the pump 30 near the separation membrane assembly 20 and arranging them at intervals along a third direction, the stability of the connection between the pump 30 and the device housing 10 can be enhanced. Furthermore, by placing the inlet 31 and the outlet 32 ​​between the first pump support 331 and the second pump support 332, the arrangement of the pump support 33 with the inlet 31 and the outlet 32 ​​becomes more compact, thereby making the internal structure of the oxygen generator 100 more compact and improving the space utilization rate within the housing 11.

[0101] refer to Figure 2 According to some embodiments of the present invention, the separation membrane assembly 20 is detachably connected to the device housing 10.

[0102] For example, the separation membrane assembly 20 can be connected to the device housing 10 by means of screws, clips, etc.

[0103] By making the separation membrane assembly 20 detachably connected to the device housing 10, the installation and separation of the separation membrane assembly 20 and the device housing 10 can be realized, which facilitates the replacement and maintenance of the separation membrane assembly 20.

[0105] For example, there may be one or more separation membrane components 22. When there are multiple separation membrane components 22, the multiple separation membrane components 22 may be arranged at intervals along the first direction and fixed on the mounting bracket 21 respectively.

[0106] For example, the separation membrane component 22 is detachably connected to the mounting bracket 21, and the mounting bracket 21 is detachably connected to the device housing 10.

[0107] By mounting the separation membrane component 22 onto the mounting bracket 21, the stability of the installation of the separation membrane component 22 can be improved, making it less likely to deviate from its original installation position. When there are multiple separation membrane components 22, multiple separation membrane components 22 can be mounted onto the mounting bracket 21, and then the separation membrane assembly 20 can be installed into the device housing 10 as a whole. During disassembly, the separation membrane assembly 20 can be removed as a whole, and then multiple separation membrane components 22 can be disassembled, reducing the difficulty of installing and disassembling the separation membrane components 22. Furthermore, by connecting the mounting bracket 21 to the device housing 10, the stability of the installation of the separation membrane assembly 20 is also improved.

[0108] refer to Figures 1-2 According to some embodiments of the present invention, the separation membrane assembly 20 has air channels 23 communicating with the receiving cavity 11 on both sides along the first direction.

[0109] For example, air can enter the device housing 10 from the air intake structure 12 and flow into the air channel 23. The separation membranes on both sides of the separation membrane assembly 20 along the first direction can contact the air in the air channel 23 and enrich the oxygen in the air in the air channel 23 into the oxygen-enriching chamber of the separation membrane assembly 20 through the separation membrane.

[0110] By forming air channels 23 communicating with the receiving cavity 11 on both sides of the separation membrane assembly 20 along the first direction, air can flow in the air channels 23, which is beneficial for both sides of the separation membrane assembly 20 to enrich oxygen through the air channels 23, thereby improving the oxygen enrichment efficiency of the separation membrane assembly 20.

[0111] refer to Figures 1-2 According to some embodiments of the present invention, the separation membrane assembly 20 includes a plurality of separation membrane components 22 arranged at intervals along a first direction, each separation membrane component 22 having an oxygen-enriched cavity, and an air flow channel 23 communicating with the receiving cavity 11 is defined between adjacent separation membrane components 22.

[0112] By providing multiple separation membrane components 22, the contact area between the separation membrane components 22 and the air can be increased, thereby improving the overall working efficiency of the separation membrane assembly 20. Furthermore, by defining air channels 23 that communicate with the receiving cavity 11 between adjacent separation membrane components 22, it is beneficial for each separation membrane component 22 to come into contact with the air in the air channels 23 and to enrich oxygen through the air channels 23, thereby improving the oxygen enrichment efficiency of the separation membrane assembly 20.

[0113] refer to Figures 1-2According to some embodiments of the present invention, the separation membrane assembly 20 has air channels 23 communicating with the receiving cavity 11 on both sides along the first direction. The separation membrane assembly 20 includes a plurality of separation membrane components 22 arranged at intervals along the first direction. Each separation membrane component 22 has an oxygen-enriched cavity, and air channels 23 communicating with the receiving cavity 11 are also defined between adjacent separation membrane components 22.

[0114] By forming air channels 23 communicating with the receiving cavity 11 on both sides of the separation membrane assembly 20 along the first direction, and defining air channels 23 communicating with the receiving cavity 11 between adjacent separation membrane components 22, air channels 23 can be present on both sides of each separation membrane component 22. This is beneficial for both sides of each separation membrane component 22 to contact the air in the air channels 23, and for oxygen to be enriched through the air channels 23, thereby improving the oxygen enrichment efficiency of the separation membrane assembly 20.

[0115] refer to Figure 1 According to some embodiments of the present invention, the ratio of the width dimension of the separation membrane assembly 20 in the third direction to the width dimension of the device housing 10 in the third direction is greater than 0.75, and the first direction, the second direction and the third direction intersect each other.

[0116] For example, the ratio of the width dimension of the separation membrane assembly 20 in the third direction to the width dimension of the device housing 10 in the third direction can be 0.76, 0.78, 0.8, 0.82, 0.84, 0.86, 0.88, 0.9, 0.92, 0.94, 0.96, 0.98, etc.

[0117] By making the ratio of the width of the separation membrane assembly 20 in the third direction to the width of the device housing 10 in the third direction greater than 0.75, the width of the separation membrane assembly 20 in the third direction can be increased when the width of the device housing 10 in the third direction is constant, thereby increasing the area of ​​the separation membrane component 22 and improving the working efficiency of the separation membrane component 22 in separating oxygen.

[0118] refer to Figure 4 According to some embodiments of the present invention, the separation membrane assembly 20 includes a mounting bracket 21 and a plurality of separation membrane components 22, all of which are mounted on the mounting bracket 21. Each separation membrane component 22 is detachably mounted on the mounting bracket 21, facilitating the disassembly, assembly, and maintenance of the separation membrane component 22. For example, each separation membrane component 22 can be pulled out of the mounting bracket 21, and the separation membrane component 22 can be pulled out along a second direction, so that the separation membrane component 22 can be installed on or detached from the mounting bracket 21.

[0119] In some embodiments of this utility model, reference is made to Figure 4The separation membrane assembly 20 includes a mounting bracket 21 and multiple separation membrane components 22, which are spaced apart along a first direction. Each separation membrane component 22 has an oxygen-enriching chamber, and an air flow channel 23 communicating with the receiving cavity 11 is defined between adjacent separation membrane components 22. This makes the overall structure of the separation membrane assembly 22 compact and has a large contact area with air, which is beneficial to improving the efficiency of oxygen separation in the separation membrane assembly.

[0120] In some embodiments of this utility model, reference is made to Figure 4 The mounting bracket 21 includes a plurality of slots 211 spaced apart along a first direction, and the two ends of the separation membrane component 22 along a third direction are received in the slots 211; one side of the slots 211 is open along a second direction to form an insertion port 212 for the separation membrane component 22 to be inserted into the slots 211.

[0121] For example, when assembling the separation membrane assembly 20, the separation membrane component 22 can be inserted into the mounting bracket 21 along the second direction through the insertion port 212 on the mounting bracket 21, so that the two ends of the separation membrane component 22 along the third direction are inserted into the slots 211 at both ends of the mounting bracket along the third direction.

[0122] By providing a plurality of slots 211 spaced apart along the first direction on the mounting bracket 21, it is easy to install the separation membrane component 22 onto the mounting bracket 21, and it is easy to insert the separation membrane component 22 into the mounting bracket 21 along the second direction or to pull the separation membrane component 22 out of the mounting bracket 21 along the second direction.

[0123] refer to Figure 1 According to some embodiments of the present invention, the inlet 31 is connected to the end of the separation membrane assembly 20 near the pump 30 along the second direction.

[0124] For example, inlet 31 can be connected to the separation membrane assembly 20 via inlet pipe 35.

[0125] By connecting the inlet 31 to the end of the separation membrane assembly 20 along the second direction near the pump 30, the connection distance between the inlet 31 and the separation membrane assembly 20 is reduced, which facilitates the connection between the inlet 31 and the separation membrane assembly 20. This helps to shorten the length of the connecting pipeline between the inlet 31 of the pump 30 and the separation membrane assembly 20, and also makes the internal layout of the oxygen generator 100 more compact, improving the space utilization rate in the housing cavity 11. Thus, under the condition that the oxygen generator 100 has a certain oxygen generation power, it is beneficial to reduce the volume of the oxygen generator 100.

[0126] refer to Figures 1-2According to some embodiments of the present invention, the separation membrane assembly 20 includes a mounting bracket 21 and a separation membrane component 22. The separation membrane component 22 is mounted on the mounting bracket 21, and the mounting bracket 21 is connected to the device housing 10. The separation membrane component 22 includes a separation membrane body 221 and a connecting joint 222. The separation membrane body 221 has an oxygen-enriched chamber. The connecting joint 222 is connected to the side of the separation membrane body 221 along the second direction near the pump 30, and the connecting joint 222 is connected to the inlet 31.

[0127] For example, the separation membrane body 221 can gradually enrich oxygen in the air into the oxygen enrichment chamber. The oxygen enriched in the oxygen enrichment chamber enters the input pipe 35 from the oxygen enrichment chamber through the connection joint 222, and then enters the pump 30 through the inlet 31. Driven by the pump 30, it enters the oxygen output pipeline 40 through the outlet 32 ​​of the pump 30, and finally is delivered to the room through the oxygen output pipeline 40 to increase the oxygen content of the indoor air.

[0128] By connecting the connector 222 to the side of the separation membrane body 221 near the pump 30 along the second direction, it is convenient to connect the inlet 31 and the separation membrane assembly 20, reducing the connection distance between the inlet 31 and the connector 222. This facilitates the connection between the inlet 31 and the separation membrane assembly 20 via pipes or other means, and also makes the internal layout of the oxygen generator 100 more compact, improving the space utilization rate within the housing 11. Thus, under the condition that the oxygen generator 100 has a certain oxygen generation power, it is beneficial to reduce the volume of the oxygen generator 100. Furthermore, by providing the connector 222 to the separation membrane component 22, it is convenient to connect the separation membrane component 22 to the inlet 31 of the pump 30, and the connector 222 can enhance the stability of the connection between the separation membrane component 22 and the inlet 31 of the pump 30.

[0129] refer to Figure 7 According to some embodiments of the present invention, the separation membrane assembly 20 includes a plurality of separation membrane components 22 arranged at intervals along a first direction, and an air flow channel 23 is defined between adjacent separation membrane components 22; wherein, the oxygen generating device 100 further includes a pipe connector 50, the pipe connector 50 having a first interface 51 and a plurality of second interfaces 52, the plurality of second interfaces 52 being arranged along the first direction, the first interface 51 being connected to the inlet 31, the number of second interfaces 52 being the same as the number of separation membrane components 22 and corresponding one-to-one, and each second interface 52 being connected to the connecting connector 222 of the corresponding separation membrane component 22.

[0130] For example, each second interface 52 can be connected to the connecting connector 222 by means of interference fit or the same means as the first interface 51 and the inlet 31. For example, the connecting connector 222 of each separation membrane component 22 is inserted into the corresponding second interface 52.

[0131] By providing a pipe connector 50, and connecting the first interface 51 of the pipe connector 50 to the inlet 31, and the number of the second interfaces 52 being the same as the number of separation membrane components 22 and corresponding one-to-one, it is convenient to connect multiple separation membrane components 22 of the separation membrane assembly 20 to the inlet 31 of the pump 30. This facilitates the connection of the oxygen-enriching chambers of multiple separation membrane components 22 to the inlet 31 of the pump 30, eliminating the need for each separation membrane component 22 to be individually connected to the inlet 31 of the pump 30. This makes the connection operation between the separation membrane assembly 20 and the inlet 31 of the pump 30 more convenient and also makes the arrangement of the pump 30 and the separation membrane assembly 20 more compact, thereby improving the space utilization rate within the accommodating cavity 11. Under the condition that the oxygen generating power of the oxygen generating device 100 is constant, it is beneficial to reduce the volume of the oxygen generating device 100.

[0132] refer to Figures 1-2 According to some embodiments of the present invention, the oxygen generating device 100 further includes a limiting bracket 60, which is fixed to the device housing 10 or the mounting bracket 21. A limiting space is defined between the limiting bracket 60 and the device housing 10 or the mounting bracket 21, and the pipe joint 50 is located within the limiting space.

[0133] When the limiting bracket 60 is fixed to the device housing 10, a limiting space is defined between the limiting bracket 60 and the device housing 10; when the limiting bracket 60 is fixed to the mounting bracket 21, a limiting space is defined between the limiting bracket 60 and the mounting bracket 21.

[0134] For example, the limiting bracket 60 can be fixed to the device housing 10. The limiting bracket 60 can be fixed to the device housing 10 by integral molding or by detachable connection. The limiting bracket 60 can also be fixed to the mounting bracket 21. The limiting bracket 60 can be fixed to the mounting bracket 21 by integral molding or by detachable connection.

[0135] By defining a limiting space between the limiting bracket 60 and the device housing 10 or the mounting bracket 21, and placing the pipe joint 50 within the limiting space, the limiting bracket 60 can limit the pipe joint 50, preventing misalignment or displacement of the pipe joint 50 from causing air leakage between the connection joint 222 of the separation membrane assembly 20 and the inlet 31 of the pump 30, thereby preventing oxygen loss.

[0136] refer to Figure 4According to some embodiments of the present invention, the mounting bracket 21 includes a plurality of slots 211 spaced apart along a first direction, and the two ends of the separation membrane component 22 along a third direction are accommodated in the slots 211; a limiting block 213 is provided on the side of the slot 211 away from the pump 30 along a second direction, and the side of the slot 211 close to the pump 30 along the second direction is open to form an insertion port 212 for the separation membrane component 22 to be inserted into the slot 211; the limiting bracket 60 is located on the side of the mounting bracket 21 close to the pump and abuts against the separation membrane body 221.

[0137] For example, when assembling the separation membrane assembly 20, the separation membrane component 22 can be inserted into the mounting bracket 21 along the second direction through the insertion port 212 on the mounting bracket 21, so that the two ends of the separation membrane component 22 along the third direction are inserted into the slots 211 at both ends of the mounting bracket along the third direction. The separation membrane component 22 is pushed into the slots 211 along the second direction and away from the pump 30 until the separation membrane component 22 abuts against the limiting block 213. At this time, the separation membrane component 22 is installed in place. Then, the pipe connector 50 is connected to the second interface 52 of the multiple separation membrane components 22, and then the limiting bracket 60 is installed to fix it on the mounting bracket 21.

[0138] By providing multiple slots 211 spaced apart along the first direction on the mounting bracket 21, the separation membrane component 22 can be easily installed onto the mounting bracket 21, and can be easily inserted into or removed from the mounting bracket 21 along the second direction. Furthermore, a limiting block 213 is provided on the side of the slot 211 away from the pump 30 along the second direction, which prevents the separation membrane component 22 from detaching from the other side of the mounting bracket 21 along the second direction during installation. The limiting block 213 and the limiting bracket together limit the separation membrane component 22 in the second direction, ensuring reliable installation of the separation membrane component 22 within the mounting bracket. This also allows for neater installation of multiple separation membrane components 22, facilitating the connection of the second interface 52 of the multiple separation membrane components 22 to the pipe connector 50.

[0139] refer to Figures 1-2 According to some embodiments of the present invention, the oxygen output pipeline 40 includes an output pipe 41, a silencer 43 and a gas guide pipe 42. The silencer 43 is disposed inside the device housing 10 and is located on the side of the separation membrane assembly 20 close to the pump 30 along the second direction. The output pipe 41 is connected to the outlet 32, and the silencer 43 is connected between the output pipe 41 and the gas guide pipe 42.

[0140] By connecting the silencer 43 between the output pipe 41 and the gas guide pipe 42, the noise of the oxygen output from the output pipe 41 can be reduced. The oxygen with reduced noise is then delivered to the room through the gas guide pipe 42 to reduce the noise when the oxygen is delivered to the room. For example, the receiving cavity 11 in the device housing 10 can be divided into a first receiving area 111 and a second receiving area 112 along the second direction. The separation membrane assembly 20 is located in the first receiving area 111, and the pump 30 is located in the second receiving area 112. By placing the silencer 43 in the device housing 10 and on the side of the separation membrane assembly 20 closer to the pump 30 along the second direction, that is, by placing both the pump 30 and the silencer 43 in the second receiving area 112, the space in the second receiving area 112 can be effectively utilized. In this way, the separation membrane assembly 20 can make full use of the space in the first receiving area 111, which is conducive to increasing the area of ​​the separation membrane assembly 20 and improving the working efficiency of the separation membrane assembly 20 in separating oxygen.

[0141] refer to Figure 1 According to some embodiments of the present invention, the silencer 43 is located on one side of the pump 30 along a third direction, where the first direction, the second direction, and the third direction intersect each other.

[0142] By positioning the silencer 43 on one side of the pump 30 along the third direction, the space of the pump 30 along the third direction can be effectively utilized, improving the space utilization rate within the accommodating cavity 11. Under the condition that the oxygen generating power of the oxygen generating device 100 is constant, it is beneficial to reduce the length of the oxygen generating device 100 in the first and second directions, thereby reducing the volume of the oxygen generating device 100.

[0143] refer to Figure 1 According to some embodiments of the present invention, at least a portion of the silencer 43 is disposed opposite to the pump 30 in a third direction.

[0144] For example, at least a portion of the muffler 43 may be disposed opposite to the pump 30 in a third direction. This could be a part of the muffler 43 disposed opposite to the pump 30 in a third direction, or the entire muffler 43 may be disposed opposite to the pump 30 in a third direction.

[0145] By arranging at least a portion of the silencer 43 opposite to the pump 30 in a third direction, the arrangement of the pump 30 and the silencer 43 within the device housing 10 can be made more compact, improving the space utilization rate within the receiving cavity 11 and reducing the volume of the oxygen generating device 100 while maintaining a certain oxygen generating power.

[0146] refer to Figure 1According to some embodiments of the present invention, the muffler 43 extends along the second direction. By extending the muffler 43 along the second direction, the space of the pump 30 along the third direction can be fully utilized, making the arrangement of the pump 30 and the muffler 43 within the device housing 10 more compact and further improving the space utilization rate within the receiving cavity 11.

[0147] refer to Figure 6 According to some embodiments of the present invention, the dimension of the muffler 43 along the first direction is smaller than the dimension of the muffler 43 along the second direction.

[0148] By making the dimension of the muffler 43 along the first direction smaller than the dimension of the muffler 43 along the second direction, and making the thickness direction of the muffler 43 parallel to the first direction and the length direction of the muffler 43 arranged along the second direction, the muffler 43 can be placed flat relative to the device housing 10. This makes the installation of the muffler 43 more stable and can make full use of the space in the receiving cavity 11, reducing the space occupied by the muffler 43 in the first direction. This makes the internal structure of the oxygen generating device 100 more compact and improves the space utilization rate in the receiving cavity 11. Thus, under the condition that the oxygen generating power of the oxygen generating device 100 is constant, it is beneficial to reduce the volume of the oxygen generating device 100.

[0149] refer to Figure 6 According to some embodiments of the present invention, the silencer 43 is provided with a first connector 431 along the third direction near the pump 30, the first connector 431 is connected to the output pipe 41, and the silencer 43 is provided with a second connector 432 along the second direction and near the separation membrane assembly 20, the second connector 432 is connected to the air guide pipe 42.

[0150] For example, oxygen-enriched gas enters the silencer 43 from the pump 30 through the output pipe 41 and the first connector 431. After the silencer 43 reduces the noise of the oxygen-enriched gas, the oxygen-enriched gas enters the air guide pipe 42 from the second connector 432. The air guide pipe 42 can deliver the oxygen-enriched gas to a preset area, such as indoors.

[0151] By placing the first connector 431 on the side of the muffler 43 along the third direction near the pump 30, the connection between the pump 30 and the muffler 43 can be facilitated, and the length of the output pipe 41 can be reduced. By placing the second connector 432 on the side of the muffler 43 along the second direction and near the separation membrane assembly 20, the output pipe 41 and the air guide pipe 42 are located on different sides of the muffler 43, making the arrangement of the output pipe 41, the air guide pipe 42 and the muffler 43 in the device housing 10 more compact and improving the space utilization rate in the receiving cavity 11.

[0152] refer to Figure 1According to some embodiments of the present invention, the separation membrane assembly 20 defines a pipe channel 24 between the third direction side and the device housing 10. The pipe channel 24 is located on the second direction side of the silencer 43 and extends in the second direction. The air guide pipe 42 is arranged along the pipe channel 24.

[0153] For example, the device housing 10 is provided on one side of the pipe hole 16 along the second direction, the pipe hole 16 and the silencer 43 are located on both sides of the pipe passage 24 along the second direction, the air guide pipe 42 runs along the pipe passage 24 to the pipe hole 16, and extends out of the device housing 10 through the pipe hole 16.

[0154] By defining a tube passage 24 between the separation membrane assembly 20 and the device housing 10 along the third direction, and arranging the gas guide tube 42 along the tube passage 24, the gap between the separation membrane assembly 20 and the device housing 10 along the third direction can be fully utilized, and the arrangement of the gas guide tube 42 can be facilitated. The tube passage 24 extending along the second direction can also reduce the frequent changes in the gas flow direction in the gas guide tube 42, making the gas flow smoother. Furthermore, by utilizing the space between the separation membrane assembly 20 and the housing along the second direction, the arrangement of the gas guide tube 42 and the separation membrane assembly 20 in the device housing 10 can be made more compact, improving the space utilization rate in the receiving cavity 11.

[0155] According to some embodiments of the present invention, the silencer 43 is detachably connected to the oxygen output pipe 41.

[0156] For example, the silencer 43 and the oxygen output pipe 41 can be connected by screws, clips, interference fits, etc.

[0157] By making the silencer 43 detachably connected to the oxygen output pipe 41, the installation and separation of the silencer 43 and the oxygen output pipe 41 can be realized, which facilitates the replacement and maintenance of the oxygen output pipe 41 and the silencer 43.

[0158] According to some embodiments of the present invention, the muffler 43 is detachably connected to the device housing 10.

[0159] For example, the muffler 43 and the device housing 10 can be connected by screws, clips, interference fits, etc.

[0160] By making the muffler 43 detachably connected to the device housing 10, the muffler 43 can be fixed to the device housing 10, enhancing the stability of the connection of the muffler 43. It is also possible to remove the muffler 43 from the device housing 10, making it convenient for the replacement and maintenance of the muffler 43.

[0161] refer to Figure 6According to some embodiments of the present invention, the outer wall of the muffler 43 is provided with mounting lugs 433, and the mounting lugs 433 are connected to the device housing 10 by fasteners.

[0162] For example, there can be one or more mounting lugs 433. When there are multiple mounting lugs 433, they can be arranged circumferentially along the outer wall of the muffler 43.

[0163] By providing mounting lugs 433 on the outer wall of the muffler 43 and connecting them with fasteners, the stability of the connection between the muffler 43 and the device housing 10 can be enhanced, making it less likely for the muffler 43 to deviate from its original installation position.

[0164] refer to Figure 6 According to some embodiments of the present invention, the silencer 43 includes a silencer box 434 and a silencer baffle 435. The silencer box 434 has a silencer cavity. Oxygen output from the pump 20 enters the silencer cavity through the output pipe (41), which can silence and reduce the noise of the airflow and reduce the transmission of airflow noise to the room.

[0165] At least a portion of the silencing baffle 435 is located within the silencing cavity. The silencing baffle 435 extends along a second direction to form a first silencing channel and a second silencing channel located on opposite sides of the thickness direction of the silencing baffle 435 within the silencing cavity. The end of the silencing baffle 435 near the separation membrane assembly 20 is connected to the inner wall of the silencing cavity, and the end of the silencing baffle 435 away from the separation membrane assembly 20 is spaced apart from the inner wall of the silencing cavity to define a third silencing channel between the end of the silencing baffle 435 away from the separation membrane assembly 20 and the silencing box 434. The third silencing channel is located on the same side of the first and second silencing channels in the second direction and connects the first and second silencing channels. The third, first, and second silencing channels are arranged in a "U" shape. The output pipe 41 is connected to the end of the first silencing channel near the separation membrane assembly 20, and the air guide pipe 42 is connected to the end of the second silencing channel near the separation membrane assembly 20.

[0166] For example, at least a portion of the sound-absorbing baffle 435 may be located within the sound-absorbing cavity. This could mean that a portion of the sound-absorbing baffle 435 is located within the sound-absorbing cavity, or that all of the sound-absorbing baffle 435 is located within the sound-absorbing cavity.

[0167] For example, when oxygen passes through the silencer 43, it first flows from the output pipe 41 through the first connector 431 into the first silencer channel of the silencer 43, then flows through the third silencer channel and the second silencer channel in sequence, and finally flows out from the second connector 432 into the gas guide pipe 42.

[0168] By setting a sound-absorbing baffle 435 in the sound-absorbing cavity, a first sound-absorbing channel and a second sound-absorbing channel are formed on opposite sides of the thickness direction of the sound-absorbing baffle 435 in the sound-absorbing cavity, and a third sound-absorbing channel is formed on the same side of the first and second sound-absorbing channels in the second direction. The third sound-absorbing channel connects the first and second sound-absorbing channels, which can make full use of the space in the sound-absorbing cavity, so that the total length of the sound-absorbing channels in the sound-absorbing cavity can be extended. When oxygen passes through the sound-absorbing channels, the sound-absorbing and noise reduction effect is better. At the same time, the length of the silencer 43 is reduced, avoiding the silencer 43 from occupying too much space in the receiving cavity 11 due to its excessive length. This improves the space utilization rate in the receiving cavity 11, thereby helping to reduce the volume of the oxygen generating device 100 when the oxygen generating power of the oxygen generating device 100 is constant.

[0169] refer to Figures 1-2 According to some embodiments of the present invention, the oxygen generating device 100 includes a capacitor 70, which is disposed inside the device housing 10 and is electrically connected to the pump 30.

[0170] For example, capacitor 70 can be electrically connected to pump 30 via wires.

[0171] By placing the capacitor 70 inside the device housing 10, maintenance and replacement of the capacitor 70 are facilitated, and the connection distance between the capacitor 70 and the pump 30 is reduced, thereby shortening the length of the connecting wire harness 80 between the capacitor 70 and the pump 30. For example, in related technologies, when the oxygen generator 100 is used in an air conditioner outdoor unit 200, the capacitor 70, which is matched with the pump 30 of the oxygen generator 100, is usually placed in the electrical control box of the air conditioner outdoor unit 200. By placing the capacitor 70 inside the device housing 10, it is easier to connect the capacitor 70 to the pump 30, reducing the length of the wire used for electrical connection between the pump 30 and the capacitor 70.

[0172] refer to Figure 1 According to some embodiments of the present invention, the capacitor 70 is located on the side of the separation membrane assembly 20 close to the pump 30 along the second direction.

[0173] For example, the separation membrane assembly 20 is located in the first receiving area 111, and the pump 30 is located in the second receiving area 112. By placing the capacitor 70 inside the device housing 10 and on the side of the separation membrane assembly 20 close to the pump 30 along the second direction, the space in the second receiving area 112 can be effectively utilized, reducing the space occupied by the capacitor 70 in the first receiving area 111. In this way, the separation membrane assembly 20 can make full use of the space in the first receiving area 111, which is conducive to increasing the area of ​​the separation membrane assembly 20 and improving the working efficiency of the separation membrane assembly 20 in separating oxygen.

[0174] refer to Figure 1According to some embodiments of the present invention, capacitor 70 is located between separation membrane assembly 20 and pump 30.

[0175] By placing the capacitor 70 between the separation membrane assembly 20 and the pump 30, the connection distance between the capacitor 70 and the pump 30 is reduced, which can reduce the length of the wire used when the pump 30 and the capacitor 70 are electrically connected. This also makes the internal layout of the oxygen generator 100 more compact and improves the space utilization rate in the housing cavity 11. Thus, under the condition that the oxygen generator 100 has a certain oxygen generation power, it is beneficial to reduce the volume of the oxygen generator 100.

[0176] refer to Figure 5 According to some embodiments of the present invention, the outer peripheral wall of the pump 30 is provided with a plurality of pump legs 33, which are arranged at intervals along the circumference of the pump 30 and are connected to the device housing 10. The plurality of pump legs 33 includes a first pump leg 331 and a second pump leg 332. The first pump leg 331 and the second pump leg 332 are located on the side of the pump 30 near the separation membrane assembly 20, and are arranged at intervals along a third direction. The inlet 31 and the outlet 32 ​​are located between the first pump leg 331 and the second pump leg 332. The first direction, the second direction, and the third direction intersect each other. In the third direction, the capacitor 70 is located on the side of the first pump leg 331 away from the inlet 31 or the outlet 32.

[0177] By placing the capacitor 70 on the side of the first pump support 331 away from the inlet 31 or outlet 32 ​​in a third-party orientation, the space on the side of the first pump support 331 away from the inlet 31 or outlet 32 ​​can be fully utilized, making the capacitor 70 more compactly arranged in the device housing 10 and improving the space utilization rate in the receiving cavity 11. Under the condition that the oxygen generating power of the oxygen generating device 100 is constant, it is beneficial to reduce the volume of the oxygen generating device 100. In addition, it reduces the wire obstruction when the pump support 33 makes electrical connection to the capacitor 70, making it easier to install and remove the capacitor 70.

[0178] refer to Figure 1 According to some embodiments of this utility model, the oxygen output pipeline 40 includes an output pipe 41, a silencer 43, and a gas guide pipe 42. The silencer 43 is disposed inside the device housing 10 and is located on the side of the separation membrane assembly 20 along the second direction near the pump 30. The output pipe 41 is connected to the outlet 32, and the silencer 43 is connected between the output pipe 41 and the gas guide pipe 42. The silencer 43 is located on the side of the pump 30 along the third direction, and is located on the side of the second pump support 332 away from the inlet 31 or the outlet 32.

[0179] By positioning the silencer 43 on one side of the pump 30 along the third direction and placing the silencer 43 on the side of the second pump support 332 away from the inlet 31 or outlet 32, the space on one side of the pump 30 along the third direction can be fully utilized. This allows the silencer 43 and capacitor 70 to be arranged on both sides of the pump support 33 and the inlet 31 and outlet 32 ​​of the pump 30 along the third direction, making full use of this space. This allows components such as the pump 30, silencer 43, and capacitor 70 to be compactly arranged in the second receiving area 112, improving the space utilization rate in the receiving cavity 11. Under the condition that the oxygen generating power of the oxygen generating device 100 is constant, it is beneficial to reduce the volume of the oxygen generating device 100.

[0180] According to some embodiments of the present invention, the capacitor 70 is detachably connected to the device housing 10.

[0181] For example, capacitor 70 and device housing 10 can be connected by screws, clips, interference fits, etc.

[0182] By making the capacitor 70 detachably connected to the device housing 10, the capacitor 70 can be fixed to the device housing 10, enhancing the stability of the capacitor 70 connection. The capacitor 70 can also be removed from the device housing 10, facilitating the replacement and maintenance of the capacitor 70.

[0183] refer to Figure 2 According to some embodiments of the present invention, the outer cover of the capacitor 70 is provided with a protective box 71.

[0184] For example, the protective box 71 can be made of metal or plastic.

[0185] By providing a protective box 71 to the outside of the capacitor 70, the capacitor 70 can be protected from external impacts and water ingress, thereby extending its service life.

[0186] According to some embodiments of this utility model, the protective box 71 is a metal part.

[0187] For example, the metal parts can be made of aluminum or stainless steel.

[0188] By making the protective box 71 a metal part, the structural strength of the protective box 71 can be enhanced, giving it higher impact resistance and deformation resistance, thereby preventing the internal capacitor 70 from being damaged. In addition, the metal protective box 71 has good fire resistance, so when a fire occurs in the outside, the protective box 71 can prevent the fire from directly contacting the capacitor 70 and causing the capacitor 70 to explode.

[0189] According to some embodiments of the present invention, the protective box 71 is detachably connected to the device housing 10.

[0190] For example, the protective box 71 and the device housing 10 can be connected by screws, clips, interference fits, etc.

[0191] By making the protective box 71 detachably connected to the device housing 10, the protective box 71 can be fixed to the device housing 10, enhancing the stability of the connection of the protective box 71. It can also be removed from the device housing 10, facilitating the replacement and maintenance of the capacitor 70.

[0192] refer to Figure 1 According to some embodiments of the present invention, the wiring harness 80 connected to the pump 30 is arranged separately from the pipeline connected to the pump 30, and the pipeline includes an oxygen output pipeline 40.

[0193] For example, the pipeline may include an oxygen output pipeline 40, and may also include an input pipeline 35.

[0194] By arranging the wiring harness 80 connected to the pump 30 and the pipeline connected to the pump 30 separately, it is convenient to assemble, disassemble and maintain the wiring harness 80 and the pipeline. The wiring harness 80 and the pipeline can also be arranged in different positions within the housing 11, making the wiring harness 80 connected to the pump 30 and the pipeline connected to the pump 30 more compact in the space within the device housing 10, improving the space utilization rate within the housing 11, and reducing the volume of the oxygen generating device 100 under the condition that the oxygen generating power of the oxygen generating device 100 is constant.

[0195] refer to Figure 5 According to some embodiments of the present invention, the pump 30 has a wire outlet 34, through which the wire harness 80 connected to the pump 30 exits. The wire outlet 34 is located on the side of the pump 30 away from the separation membrane assembly 20, and the inlet 31 and outlet 32 ​​are located on the side of the pump 30 closer to the separation membrane assembly 20.

[0196] By placing the outlet hole 34 on the side of the pump 30 away from the separation membrane assembly 20, it is convenient for the wiring harness 80 to run through the outlet hole 34. By placing the inlet 31 and outlet 32 ​​on the side of the pump 30 close to the separation membrane assembly 20, it is convenient for the pipeline to run through the inlet 31 and outlet 32, reducing the connection distance between the inlet 31 and the separation membrane assembly 20. By placing the outlet hole 34, inlet 31, and outlet 32 ​​on different sides of the pump 30, it is convenient for the assembly, disassembly, and maintenance of the wiring harness 80 and the pipeline. It also makes the wiring harness 80 connected to the pump 30 and the pipeline connected to the pump 30 more compact in the space within the device housing 10, improving the space utilization rate within the receiving cavity 11. Under the condition that the oxygen generating power of the oxygen generating device 100 is constant, the volume of the oxygen generating device 100 is reduced.

[0197] refer to Figure 1According to some embodiments of the present invention, the separation membrane assembly 20 defines a pipe channel 24 and a wiring channel 25 between its two sides along a third direction and the device housing 10, respectively. The first direction, the second direction, and the third direction intersect each other. The pipe channel 24 and the wiring channel 25 both extend along the second direction. At least a portion of the oxygen output pipeline 40 is arranged along the pipe channel 24, and at least a portion of the wiring harness 80 is arranged along the wiring channel 25.

[0198] For example, at least a portion of the oxygen output pipeline 40 is arranged along the pipeline channel 24. This could be a part of the oxygen output pipeline 40 arranged along the pipeline channel 24, or the entire oxygen output pipeline 40 could be arranged along the pipeline channel 24. At least a portion of the wiring harness 80 is arranged along the wiring channel 25. This could be a part of the wiring harness 80 arranged along the pipeline channel 24, or the entire wiring harness 80 could be arranged along the pipeline channel 24.

[0199] By defining the pipe channel 24 and the wiring channel 25 respectively, and arranging at least a portion of the oxygen output pipeline 40 along the pipe channel 24 and at least a portion of the wiring harness 80 along the wiring channel 25, the oxygen output pipeline 40 and the wiring harness 80 are arranged separately, which facilitates the assembly, disassembly and maintenance of the wiring harness 80 and the pipeline. Furthermore, by extending both the pipe channel 24 and the wiring channel 25 along the second direction, the wiring harness 80 connected to the pump 30 and the pipeline connected to the pump 30 can be arranged more compactly in the space within the device housing 10, thereby improving the space utilization rate within the receiving cavity 11.

[0200] refer to Figures 1-3 According to some embodiments of the present invention, the device housing 10 includes a side panel 14 and a bottom plate 15. The side panel 14 is disposed on the bottom plate 15 and is connected to the outer edge of the bottom plate 15. The side panel 14 extends circumferentially along the bottom plate 15 and the side panel 14 and the bottom plate 15 together define a receiving cavity 11. The receiving cavity 11 is located on one side of the bottom plate 15 along a first direction. An air inlet structure 12 is formed on the side panel 14 and an air outlet structure 13 is formed on the bottom plate 15.

[0201] For example, when the first direction is up and down, the receiving cavity 11 is located on the upper side of the base plate 15.

[0202] For example, the side panel 14 may be provided with pipe holes 16 to facilitate the oxygen delivery pipeline to run from inside the device housing 10 to the outside of the device housing 10 and then connect to the room.

[0203] For example, air enters the housing 11 through the air intake structure 12 of the side panel 14, and after oxygen is separated by the separation membrane assembly 20 located in the housing 11, it is then transported to the room through the oxygen delivery pipeline under the drive of the pump 30. The remaining gas in the housing 11 is discharged to the outside of the device housing 10 through the air outlet structure 13 of the bottom plate 15.

[0204] By forming the air intake structure 12 on the side panel 14 and the air outlet structure 13 on the bottom plate 15, it is beneficial for air to flow from the air intake structure 12 into the receiving cavity 11 and through the separation membrane assembly 20. Air with low oxygen content is discharged from the air outlet structure 13 in a timely manner, which promotes the circulation of air in the receiving cavity 11 and thus improves the working efficiency of the separation membrane assembly 20 in separating oxygen.

[0205] refer to Figures 1-3 According to some embodiments of the present invention, at least a portion of the air intake structure 12 is located on the side of the separation membrane assembly 20 away from the pump 30 along the second direction.

[0206] For example, at least a portion of the intake structure 12 may be located on the side of the separation membrane assembly 20 away from the pump 30 along the second direction. This could be a part of the intake structure 12 located on the side of the separation membrane assembly 20 away from the pump 30 along the second direction, or the entire intake structure 12 may be located on the side of the separation membrane assembly 20 away from the pump 30 along the second direction.

[0207] By positioning at least a portion of the intake structure 12 on the side of the separator membrane assembly 20 facing away from the pump 30 in the second direction, it facilitates the flow of air from the intake structure 12 into the receiving cavity 11 and through the separator membrane assembly 20. This prevents the pump 30 in the second direction from obstructing the airflow through the separator membrane assembly 20 and also reduces the airflow path between the intake structure 12 and the separator membrane assembly 20, resulting in less airflow resistance, smoother flow, and lower flow noise in the receiving cavity 11.

[0208] refer to Figures 1-3 According to some embodiments of the present invention, a portion of the air intake structure 12 is located on the outer periphery of the pump 30.

[0209] For example, a portion of the intake structure 12 may be located on the outer periphery of the pump 30. This could be either a portion of the intake structure 12 located on the side panel 14 adjacent to the pump 30 along the second direction, or a portion of the intake structure 12 located on the side panel 14 adjacent to the pump 30 along the third direction.

[0210] By positioning part of the air intake structure 12 on the outer periphery of the pump 30, airflow around the pump 30 is facilitated. Air entering the housing cavity 11 from the air intake structure 12 can flow through the pump 30 and carry away the heat generated by the pump 30, thereby enhancing the heat dissipation effect of the pump 30.

[0211] refer to Figures 1-3 According to some embodiments of the present invention, the pump 30 has a wire outlet hole 34, and the wire harness 80 connected to the pump 30 exits through the wire outlet hole 34. The wire outlet hole 34 and the wire harness 80 are both offset from the air intake structure 12.

[0212] By staggering the outlet hole 34 and the wiring harness 80 from the air inlet structure 12, water or other liquids can be prevented from directly contacting the outlet hole 34 and the wiring harness 80 when entering the housing cavity 11 from the air inlet structure 12. This prevents water from entering the pump 30 and damaging the pump 30, or water from entering the wiring harness 80 and damaging the wiring harness 80.

[0213] According to some embodiments of the present invention, at least a portion of the air outlet structure 13 is located directly below the pump 30.

[0214] For example, at least a portion of the air outlet structure 13 may be located directly below the pump 30. This could mean that a portion of the air outlet structure 13 is located directly below the pump 30, or that the entire air outlet structure 13 is located directly below the pump 30.

[0215] By positioning at least a portion of the exhaust structure 13 directly below the pump 30, the gas in the containment cavity 11 can fully contact the pump 30 and carry away the heat generated by the pump 30 as it flows toward the exhaust structure 13, thereby enhancing the heat dissipation effect of the pump 30.

[0216] refer to Figure 3 According to some embodiments of this utility model, a baffle 152 is provided at a part of the air outlet structure 13, and a drain hole is provided at the lower end of the pump 30. When the pump 30 is working, the condensate generated in the pump can be discharged through the drain hole. The baffle 152 is located directly below the drain hole to block the drain hole in the downward direction. The condensate in the pump 30 can be discharged downward through the drain hole onto the baffle 152. The water discharged from the drain hole onto the baffle 152 can flow to other parts of the air outlet structure 13 and be discharged downward through other parts of the air outlet structure 13 into the fan cavity. The baffle 152 can prevent the drain hole from directly discharging downward through the air outlet structure 13 into the fan cavity below the oxygen generator 100. This can prevent the water discharged directly downward through the air outlet structure 13 into the fan cavity from being thrown up by the fan running in the fan cavity and entering the pump 30 through the air outlet structure 13.

[0217] For example, the lower end of the pump 30 may have one or more drain holes. When there are multiple drain holes, multiple baffles 152 are located directly below the multiple drain holes.

[0218] By providing a baffle 152 directly below the drain hole to block the drain hole in the downward direction, the airflow flowing under the air outlet structure 13 during draining can prevent the water discharged from the drain hole from being blown back into the pump 30 through the drain hole. This allows the water discharged from the drain hole to be drained through the air outlet structure 13 around the baffle 152, reducing the amount of water splashing back into the pump 30 during draining.

[0219] refer to Figures 1-3According to some embodiments of the present invention, a portion of the base plate 15 is recessed in the direction away from the receiving cavity 11, so that a receiving groove 151 is formed on the side of the base plate 15 facing the receiving cavity 11, and the pump 30 is located in the receiving groove 151.

[0220] For example, the pump 30 is located within the receiving groove 151, or a portion of the pump 30 may be located within the receiving groove 151.

[0221] For example, when the first direction is up and down, part of the base plate 15 can be recessed downwards.

[0222] By recessing a portion of the base plate 15 in a direction away from the receiving cavity 11 to form a receiving groove 151, and placing the pump 30 in the receiving groove 151, the installation and positioning of the pump 30 is facilitated. Furthermore, the pump 30 will not protrude from the separation membrane assembly 20 on the side away from the receiving groove 151 in the first direction, thus reducing the waste of space in the separation membrane assembly 20 in the first direction and improving the space utilization rate in the receiving cavity 11, thereby making the overall space ratio of the oxygen generating device 100 smaller.

[0223] refer to Figures 1-3 According to some embodiments of the present invention, at least a portion of the venting structure 13 is formed on the bottom wall of the receiving groove 151.

[0224] For example, at least a portion of the venting structure 13 is formed on the bottom wall of the receiving groove 151. This could be a part of the venting structure 13 being formed on the bottom wall of the receiving groove 151, or the entire venting structure 13 being formed on the bottom wall of the receiving groove 151.

[0225] By forming at least a portion of the outlet structure 13 on the bottom wall of the receiving groove 151, the gas in the receiving cavity 11 flows through the receiving groove 151 and then out through the outlet structure 13 during its flow to the outlet structure 13. This facilitates full contact between the gas and the pump 30 in the receiving groove 151 and carries away the heat generated by the pump 30, thereby enhancing the heat dissipation effect of the pump 30.

[0226] According to some embodiments of this utility model, refer to Figure 3 The upper surface of the base plate 15 is provided with a drainage groove 153, at least a portion of which is located below the separation membrane assembly 20. The drainage groove 153 leads to the receiving groove 151. The bottom wall of the receiving groove 151 is lower than the bottom wall of the drainage groove 153. Condensate generated during the operation of the separation membrane assembly 20 and condensate generated by other components inside the device housing 10 can be collected in the drainage groove 153 on the base plate 15. The water is then guided to the receiving groove 151 through the drainage groove 153. The water flowing into the receiving groove 151 is discharged downward through the air outlet structure 13 on the bottom wall of the receiving groove 151.

[0227] For example, at least a portion of the drain channel 153 may be located below the separation membrane assembly 20. This could mean that a portion of the drain channel is located below the separation membrane assembly 20, or that the entire drain channel 153 is located below the separation membrane assembly 20.

[0228] By providing a drainage groove 153 on the upper surface of the base plate 15, water can be collected into the drainage groove 153, such as water entering the receiving cavity 11 from the air intake structure 12, condensate generated by the separation membrane assembly 20, etc. At least part of the drainage groove 153 is located below the separation membrane assembly 20 to prevent water from accumulating in the receiving cavity 11 and affecting the normal operation of the separation membrane assembly 20.

The outdoor unit housing 91 is provided with an outdoor air inlet 93 and an outdoor air outlet 92, and the oxygen generating device 100 is installed in the outdoor unit housing 91.

[0230] For example, the heat exchange and exhaust assembly may include an outdoor heat exchanger and an outdoor fan. Air enters the outdoor unit housing 91 through the outdoor air inlet 93, exchanges heat with the outdoor heat exchanger, and is then exhausted to the outside through the outdoor air outlet 92 driven by the outdoor fan.

[0231] For example, the oxygen generator 100 can be installed on top of the outdoor unit housing 91.

[0232] According to the embodiment of the present utility model, the air conditioner outdoor unit 200, by setting the above-mentioned oxygen generating device 100, has a more compact internal structure, which improves the space utilization rate of the internal cavity 11 of the oxygen generating device 100. Thus, under the condition that the oxygen generating power of the oxygen generating device 100 is constant, it is beneficial to reduce the volume of the oxygen generating device 100, reduce the space occupied by the oxygen generating device 100, and facilitate the installation and storage of the oxygen generating device 100. When the oxygen generating device 100 is installed in the air conditioner outdoor unit 200, the space occupied by the air conditioner outdoor unit 200 is also reduced.

[0233] According to some embodiments of the present invention, the oxygen generating device 100 is detachably connected to the outdoor unit housing 91.

[0234] For example, the oxygen generator 100 can be connected to the outdoor unit housing 91 by screws.

[0235] By making the oxygen generator 100 detachably connected to the outdoor unit housing 91, the installation and removal of the oxygen generator 100 are highly flexible, facilitating the maintenance or replacement of the oxygen generator 100.

[0236] refer to Figures 8-10 According to some embodiments of this utility model, the oxygen generator 100 is located on the top of the outdoor unit body 90. By placing the oxygen generator 100 on the top of the outdoor unit body 90, the space at the top of the main body 94 can be utilized, reducing the horizontal space occupied by the oxygen generator 100. It also facilitates the installation of the oxygen generator 100 onto the outdoor unit body 90, improving the assembly efficiency of the oxygen generator 100. When the oxygen generator 100 or the outdoor unit body 90 needs maintenance, the efficiency of installation and disassembly of the oxygen generator 100 and the outdoor unit body 90 can also be improved.

[0237] refer to Figures 8-10 According to some embodiments of the present invention, the oxygen generating device 100 is installed on the top of the outdoor unit housing 91. The outdoor unit housing 91 has a compressor chamber and a fan chamber arranged along a second direction. The compressor chamber and the fan chamber are separated by a partition. The heat exchange exhaust assembly is located in the fan chamber, and the compressor assembly is located in the compressor chamber. The oxygen generating device 100 is located on the top of the outdoor unit housing 91. The oxygen generating device 100 includes a device housing 10 and an oxygen generating assembly.

The side panel 14 of the device housing 10 is provided with an air inlet structure 12.

[0238] When the outdoor unit 200 of the air conditioner is working, the outdoor fan drives the outside air to enter the fan cavity from the air inlet and exchange heat with the outdoor heat exchanger before being discharged from the air outlet structure. At the same time, since the receiving cavity 11 in the device housing 10 is connected to the fan cavity through the air outlet structure 13, it can also drive the outside air to enter the receiving cavity 11 from the air inlet structure 12. The air entering the receiving cavity 11 is separated by the separation membrane assembly 20, and oxygen is enriched in the oxygen-enriched cavity of the separation membrane assembly 20. It is then transported to the indoor unit through the oxygen output pipe 41. The remaining gas is driven by the outdoor fan to enter the fan cavity from the air outlet structure 13 on the base plate 15 and is discharged from the outdoor air outlet 92.

[0239] refer to Figures 8-10According to some embodiments of the present invention, the outdoor housing 91 includes a housing body 94 and a housing top cover 95. The housing body 94 has a compressor cavity and a fan cavity arranged along a second direction. The heat exchange exhaust assembly is disposed in the fan cavity, and the compressor assembly is disposed in the compressor cavity. The housing body 94 is provided with an outdoor air inlet 93 and an outdoor air outlet 92. The fan cavity connects the outdoor air inlet 93 and the outdoor air outlet 92. The oxygen generator 100 is disposed on the top of the housing body 94, and the housing top cover 95 covers the top of the oxygen generator 100. The air outlet structure 13 connects the receiving cavity 11 and the fan cavity.

[0240] By placing the oxygen generator 100 on top of the main casing 94, the space at the top of the main casing 94 can be utilized, reducing the occupation of horizontal space. This also facilitates the installation of the oxygen generator 100 onto the main casing 94, improving the assembly efficiency of the oxygen generator 100. When the oxygen generator 100 or the outdoor unit 90 needs maintenance, the efficiency of installation and disassembly of the oxygen generator 100 and the outdoor unit 90 can also be improved. Furthermore, by placing the top cover 95 on top of the oxygen generator 100, there is no need to equip the oxygen generator 100 with a separate top cover, saving space in the outdoor unit 200 and reducing production costs.

[0241] An air conditioner according to a third aspect of the present invention includes: an indoor unit and an outdoor unit 200 according to a second aspect of the present invention, wherein an oxygen output pipeline 40 is used to deliver oxygen to the indoor unit.

[0242] For example, the oxygen output pipe 41 can deliver oxygen to the air inlet, duct, or outlet of the indoor unit of the air conditioner.

[0243] According to the embodiment of this utility model, by setting the above-mentioned outdoor unit 200, the air conditioner can have an oxygen generation function. Integrating the oxygen generation device 100 into the outdoor unit 200 can reduce the space occupied by the oxygen generation device 100 and the impact of noise generated during oxygen generation on the indoor environment. Furthermore, the internal structure of the oxygen generation device 100 is more compact, improving the space utilization rate of the internal cavity 11. Thus, under the condition of a certain oxygen generation power, it is beneficial to reduce the volume of the oxygen generation device 100, reduce the space occupied by the oxygen generation device 100, and facilitate the installation and storage of the oxygen generation device 100. When the oxygen generation device 100 is installed in the outdoor unit 200, the space occupied by the outdoor unit 200 is also reduced.

[0257] The oxygen generator 100 also includes a capacitor 70, which is disposed inside the device housing 10 and electrically connected to the pump 30.

[0259] For example, when the oxygen generator 100 is working, air enters the receiving cavity 11 of the device housing 10 from the air intake structure 12 on the device housing 10. The pump 30 starts working and generates negative pressure in the oxygen-enriching cavity. The air flows through the separation membrane assembly 20. Taking advantage of the different permeation rates of different gases in the air through the separation membrane in the separation membrane assembly 20, since the migration rate of oxygen molecules in the separation membrane is faster than that of other gases in the air, such as nitrogen molecules, oxygen in the air can pass through the separation membrane and be enriched in the oxygen-enriching cavity of the separation membrane assembly 20, thereby enriching the oxygen in the air into the oxygen-enriching cavity.

[0260] The oxygen enriched in the oxygen-enriched chamber is driven by the pump 30 and enters the pump 30 from the inlet 31 and exits from the outlet 32. Since the outlet 32 ​​of the pump 30 is connected to the oxygen output pipeline 40, the oxygen discharged from the outlet 32 ​​of the pump 30 can be output to the designated area of ​​the room through the oxygen output pipeline 40, thereby increasing the oxygen concentration in the indoor air and improving the indoor air quality.
