With technological advancements, people's demands for indoor health and comfort have further increased, and increasing the oxygen concentration in the air can effectively alleviate stuffiness. Traditional fresh air conditioners balance indoor oxygen concentration by introducing air; however, with human respiration and metabolism, the indoor oxygen concentration continuously decreases, consistently falling below outside levels. This can easily lead to stuffiness, fatigue, and other physiological discomforts, limiting user health and comfort.

[0028] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0029] As mentioned in the background section, most existing air conditioners with oxygen generation functions generate oxygen by installing an air compressor and molecular sieve in the outdoor unit. This requires a compressor drive (high energy consumption) and relies on a heating unit to prevent the molecular sieve from absorbing water and failing (complex structure), resulting in high costs. Therefore, to address the above-mentioned technical problems, the oxygen generation device of this application includes a housing 100, an oxygen generation component 200, and a power component 300. The housing 100 is provided with an air inlet channel 101, a nitrogen exhaust channel 102, and an oxygen exhaust channel 103. The oxygen generation component 200 is disposed inside the housing 100, and at least a portion of the oxygen generation component 200 is arranged opposite to the air outlet of the air inlet channel 101 to separate oxygen and nitrogen in the ambient air introduced by the air inlet channel 101. The separated oxygen is transported to a predetermined location through the oxygen exhaust channel 103, and the nitrogen is discharged through the nitrogen exhaust channel 102. The power component 300 is also provided inside the housing 100 to provide power for the airflow. Unlike traditional oxygen generation technologies, the oxygen generation component 200 of this application uses a hollow fiber membrane for nitrogen and oxygen separation, eliminating the need for energy-intensive air compressors or compressors. The oxygen generation component 200 is cleverly integrated with existing structures such as the air conditioner housing 100 and power unit 300. The oxygen generation component is located in a specific area of ​​the housing, working in conjunction with the air inlet channel 101, nitrogen exhaust channel 102, and oxygen exhaust channel 103. This avoids the need for additional air ducts and components, simplifies the internal structure, makes the overall equipment more compact, and facilitates installation and maintenance, while also reducing material and production costs.

[0030] Please refer to Figures 1 to 8This application provides an oxygen generating device, comprising: a housing 100, on which an air inlet channel 101, a nitrogen exhaust channel 102, and an oxygen exhaust channel 103 are provided; and an oxygen generating component 200 disposed within the housing 100, at least a portion of which is disposed opposite to the air outlet of the air inlet channel 101, such that when air entering through the air inlet channel 101 flows through the oxygen generating component 200, oxygen and nitrogen in the air are separated, and nitrogen is discharged to the outside of the housing 100 through the nitrogen exhaust channel 102. The oxygen generating component 200 is provided with an oxygen delivery channel, which is connected to the oxygen exhaust channel 103. The oxygen delivery channel is used to output the separated oxygen to the oxygen exhaust channel 103 so as to discharge the oxygen to a predetermined position. The power unit 300 is provided in the housing 100 and located on the side of the oxygen generating component 200 away from the air outlet. The power unit 300 is used to draw in the outside air of the housing 100 through the air inlet channel 101 into the housing 100 and discharge the nitrogen separated by the oxygen generating component 200.

[0031] According to the oxygen generating device provided in this application, the housing 100 serves as the main structure of the entire oxygen generating device. Its internal layout is rational, including an air inlet channel 101, a nitrogen exhaust channel 102, and an oxygen exhaust channel 103. The arrangement of these three channels provides the basic conditions for the directional flow and separation of airflow. The air inlet channel 101 is responsible for introducing external air, the nitrogen exhaust channel 102 is used to discharge the nitrogen separated from the oxygen generating component 200 outside the housing, and the oxygen exhaust channel 103 is used to transport the oxygen separated within the oxygen generating component to a predetermined location, such as an indoor environment, thereby directly improving indoor air quality.

[0032] The oxygen generator unit utilizes hollow fiber membrane technology for oxygen and nitrogen separation. The highly efficient physical separation characteristics of the hollow fiber membrane allow for the rapid establishment of a concentration gradient between the inside and outside of the membrane. Oxygen diffuses inward through the membrane, while nitrogen is retained on the outside, thus achieving nitrogen-oxygen separation. An oxygen delivery channel is incorporated within the oxygen generator unit, enabling the separated oxygen to be directly transported to the oxygen exhaust channel 103, preventing back diffusion and improving oxygen purity and output efficiency.

[0033] The power unit 300 is a ventilation fan or an axial flow fan. The power unit 300 is located on the side of the oxygen generating component 200 away from the air outlet of the air inlet channel 101. By generating negative or positive pressure, it forces the outside air to enter the housing 100 through the air inlet channel 101, and at the same time pushes the nitrogen separated by the oxygen generating component 200 to be discharged through the nitrogen exhaust channel 102, ensuring the continuity and efficiency of the entire oxygen generation process.

[0034] In practical implementation, the oxygen generating device also includes: an air extraction component, which is connected to the oxygen exhaust channel 103. The air extraction component is used to extract oxygen from the oxygen exhaust channel 103 to a predetermined position.

[0035] The extraction component (such as a vacuum pump or a small compressor) is closely connected to the oxygen generation assembly 200 and the oxygen exhaust channel 103, forming a complete oxygen extraction and transmission system. Sensors and controllers are installed in the extraction channel of the extraction component to monitor the oxygen concentration and pressure in the oxygen exhaust channel 103 in real time, and dynamically adjust the extraction rate according to the indoor oxygen demand or preset parameters.

[0036] The extraction component helps maintain a low oxygen concentration environment inside the membrane by timely extracting the oxygen separated from the oxygen generating unit, preventing oxygen from diffusing back and thus maintaining the high purity of the oxygen.

[0037] The oxygen generating assembly 200 includes: a hollow fiber membrane 210 disposed within the housing 100; an oxygen delivery channel located within the hollow fiber membrane 210; when air flows through the hollow fiber membrane 210 in the air inlet channel 101, the separated oxygen is retained in the oxygen delivery channel; there are multiple hollow fiber membranes 210, which are arranged side by side within the housing 100, and the oxygen delivery channel in each hollow fiber membrane 210 is connected to the oxygen exhaust channel 103.

[0038] The hollow fiber membranes 210 are designed in multiple parallel configurations, each membrane being an independent gas separation unit. When air is introduced into the air inlet channel 101 of the oxygen generator assembly 200, as the air flows through each hollow fiber membrane 210, due to the small size and high diffusion rate of oxygen molecules, oxygen can quickly permeate through the membrane wall into the oxygen delivery channel on the inner side of the membrane, while nitrogen is effectively retained outside the membrane, achieving effective separation of nitrogen and oxygen flow. The multiple parallel configurations of the hollow fiber membranes 210 significantly increase the total gas contact area with the membrane, thereby significantly improving the efficiency and speed of gas separation.

[0039] The oxygen delivery channel is located inside the hollow fiber membrane 210. Its design allows the separated oxygen to be directly retained inside the membrane, avoiding back diffusion and ensuring oxygen purity. Each oxygen delivery channel in the hollow fiber membrane 210 is connected to the oxygen exhaust channel 103. In this way, all the oxygen separated within the membrane can be effectively collected in the oxygen exhaust channel 103 and ultimately transported to a predetermined location, such as an indoor space, thus achieving efficient oxygen delivery.

[0040] like Figure 7As shown, the oxygen generating assembly 200 further includes: a first cover plate 220 and a second cover plate 230, the first cover plate 220 and the second cover plate 230 being arranged opposite to and spaced apart, and a plurality of hollow fiber membranes 210 being disposed between the first cover plate 220 and the second cover plate 230; the first cover plate 220 is provided with a plurality of spaced first through holes 221, each first through hole 221 being opposite to the hollow fiber membrane 210, and the air in the air inlet channel 101 flows through the hollow fiber membrane 210 after passing through each first through hole 221; the second cover plate 230 is provided with a plurality of spaced second through holes 231, each second through hole 231 being opposite to the hollow fiber membrane 210, and the nitrogen separated by each hollow fiber membrane 210 is discharged through the nitrogen exhaust channel 102 after passing through each second through hole 231.

[0041] The first cover plate 220 and the second cover plate 230 are arranged opposite to each other and at intervals to form a cavity to accommodate the hollow fiber membrane 210. Multiple first through holes 221 on the first cover plate 220 ensure that air can enter the inner side of the hollow fiber membrane 210 uniformly, while second through holes 231 on the second cover plate 230 allow nitrogen to escape smoothly after separation. This design not only ensures sufficient contact between air and the hollow fiber membrane but also maintains the flow direction of the gas inside and outside the membrane, improving separation efficiency.

[0042] Air from the air inlet duct 101 flows into each hollow fiber membrane 210 through the first through-hole 221 on the first cover plate 220, ensuring uniform air distribution on the membrane surface and avoiding uneven separation caused by excessive local airflow. Separated nitrogen is effectively discharged through the nitrogen exhaust duct 102 via the second through-hole 231 on the second cover plate 230, while oxygen flows through the oxygen delivery duct inside the oxygen generator to the oxygen exhaust duct 103, ultimately being output to a predetermined location. This airflow path design ensures the high efficiency and stability of the nitrogen-oxygen separation process.

[0043] The oxygen inlet end of the oxygen exhaust channel 103 is provided with a sealing component. The sealing component is located between the channel wall of the oxygen exhaust channel 103 and multiple hollow fiber membranes 210. The sealing component can be flexibly set, and the sealing component is interference-fitted with the oxygen exhaust channel 103 and the multiple hollow fiber membranes 210 respectively.

[0044] The sealing component is located between the channel wall of the oxygen exhaust channel 103 and the hollow fiber membrane 210. The purpose of this design is to form an effective seal during the process of oxygen diffusing from the inside of the fiber membrane to the oxygen exhaust channel 103, preventing the separated oxygen from being lost or diffusing in the gap between the membrane and the channel wall, and also preventing nitrogen from overflowing into the oxygen exhaust channel 103.

[0045] The sealing component is made of elastic material, which can tightly fit the channel wall of the oxygen exhaust channel 103 and the surface of the hollow fiber membrane 210 during compression and recovery deformation. The design of the elastic sealing component can adapt to the slight deformation of the fiber membrane under gas pressure, maintain good airtightness, and maintain stable oxygen output efficiency even during long-term use and maintenance.

[0046] In the specific implementation process, the oxygen generating device also includes a filter component, which is installed in the air inlet channel 101 and located at the air inlet port of the air inlet channel 101, so that the ambient air flows through the filter component for filtration and then flows into the oxygen generating assembly 200 for oxygen generation.

[0047] The filter element is located at the air inlet port of the air inlet channel 101, which is the first point where air enters the oxygen generator. The filter element is designed to remove pollutants such as particulate matter, dust, and pollen from the air to ensure that the working environment of the oxygen generator 200 is not polluted, to prevent the hollow fiber membrane from being blocked or contaminated, and thus to ensure high-quality oxygen production.

[0048] like Figure 1 As shown, the housing 100 includes: a first body 110, a power component 300 disposed within the first body 110, an air inlet channel 101 and a nitrogen exhaust channel 102 respectively disposed on the first body 110; a second body 120 connected to the first body 110, at least a portion of the oxygen generating component 200 disposed within the second body 120; and a third body 130, at least a portion of the third body 130 connected to the first body 110, with the second body 120 located between the first body 110 and the third body 130.

[0049] The first body 110 serves as the main frame of the oxygen generation device, undertaking the task of installing the power components 300, such as the ventilation fan, compressor, or vacuum pump. Simultaneously, the first body 110 is equipped with an air inlet channel 101 and a nitrogen exhaust channel 102, ensuring the introduction of external air and the discharge of nitrogen. This integrated design simplifies the external interfaces of the device, facilitating installation and maintenance.

[0050] The second body 120 is connected to the first body 110 and is mainly responsible for accommodating part or all of the oxygen generating component 200. The second body 120 is located between the first body 110 and the third body 130. This arrangement makes full use of space and avoids mutual interference between components. In particular, the isolation between the oxygen generating component 200 and the power component 300 reduces the impact of vibration and noise, and ensures the stability and efficiency of the oxygen generating process.

[0051] The third body 130 is at least partially connected to the first body 110, forming a closed container that provides necessary external protection for the oxygen generating device. Meanwhile, the second body 120 is located between the first body 110 and the third body 130. This layout optimizes the use of internal space and ensures a rational distribution of components.

[0052] The second body 120 has a first gap between its side surface and the first body 110 and the third body 130, and a second gap between its bottom surface and the third body 130. At least a portion of the first gap and at least a portion of the second gap constitute a partial air inlet channel 101.

[0053] The first gap is located on the side of the second body 120 and between the first body 110 and the third body 130, forming a lateral airflow channel. This design allows for a more uniform distribution of air upon entering the device, preventing airflow from concentrating in a particular area and thus improving the gas separation efficiency of the entire oxygen generation assembly 200. Furthermore, the first gap can also serve as a pre-filtration channel, where large particulate impurities in the air may be initially intercepted as they pass through this wider channel, reducing the burden on subsequent filtration components.

[0054] The second gap is located between the bottom surface of the second body 120 and the third body 130, serving as an airflow channel at the bottom. It allows air to flow smoothly in the vertical direction, further increasing the contact area between the air and the hollow fiber membrane 210.

[0055] The first body 110 is provided with a plurality of first protrusions 111, which are spaced apart along the circumferential direction of the first body 110; the third body 130 is provided with a buckle 131, at least a portion of which engages with the first protrusions 111 to connect the first body 110 and the third body 130. There are a plurality of buckles 131, which are provided in a one-to-one correspondence with the plurality of first protrusions 111.

[0056] Multiple first protrusions 111 are provided on the first body 110. These protrusions are evenly spaced along the circumferential direction of the first body 110, forming a ring-shaped array of connection points. The design of the first protrusions 111 not only provides stable support points for the third body 130, but also ensures good sealing and mechanical strength between the two bodies.

[0057] The third body 130 is provided with a plurality of latches 131 corresponding to the first protrusion 111. The latches 131 are also arranged along the edge of the third body 130, forming a one-to-one connection with the first protrusion 111. During assembly, each latch 131 will engage with the first protrusion 111 at the corresponding position, realizing a quick connection between the first body 110 and the third body 130.

[0058] The snap-fit ​​assembly method allows users to manually connect and separate the first body 110 and the third body 130 without any tools. During assembly, simply align the snap-fit ​​131 with the first protrusion 111 and apply a certain force to lock it in place. During disassembly, simply press the snap-fit ​​131 gently to release the locking state, and the two parts can be easily separated, greatly simplifying the maintenance and cleaning process.

[0059] like Figures 2 to 6 As shown, the first body 110 is also provided with a plurality of claws 112, and the second body 120 is provided with a plurality of second protrusions 121. Each second protrusion 121 is engaged with the corresponding claw 112. The second body 120 is also provided with a positioning notch 122. The first body 110 is also provided with a third protrusion 113. The third protrusion 113 is engaged with the positioning notch 122 to achieve positioning between the first body 110 and the second body 120. The connection between the first body 110 and the second body 120 is achieved through the cooperation of the claws 112 and the second protrusions 121.

[0060] The first body 110 is provided with multiple claws 112, which are evenly distributed along the edge of the first body to form a ring for fixing the second body 120. The claws 112 have a certain degree of elasticity and can undergo slight deformation when the second protrusion 121 is inserted, ensuring that the second protrusion 121 can be smoothly locked into the claws, while providing sufficient support force in the locked state to maintain a tight connection between the two bodies.

[0061] In addition to the snap-fit ​​connection, the second body 120 is also provided with a positioning notch 122, and the corresponding third protrusion 113 on the first body 110 is inserted into the positioning notch. This not only provides an additional positioning reference for the two bodies, ensuring the accuracy of assembly, but also further enhances the stability of the connection and avoids loosening problems during long-term use or transportation.

[0062] This application also provides an air conditioner, including an indoor unit and an oxygen generating device, wherein the oxygen generating device is disposed in the indoor unit and is the oxygen generating device described in the above embodiment.

[0063] This application designs an oxygen-generating component based on the principle of hollow fiber membrane oxygen generation technology and using a fresh air unit as a carrier. The structural diagram of the oxygen generation device is shown below. Figure 1 As shown, it includes components such as a volute, ventilation fan, air inlet connector, volute cover (first body), oxygen generating assembly, oxygen generating bracket (second body), and sealing cover (third body).

[0064] like Figure 2As shown, the oxygen generating module 200 includes symmetrically arranged fiber membrane covers (first cover 220 and second cover 230), an exhaust cover (with an oxygen exhaust channel 103 inside), and a hollow fiber membrane. The oxygen generating module employs a hollow fiber membrane bundle filling technology, arranging hollow fiber membranes of a certain diameter, inner diameter, and length in parallel bundles to fill the module cavity, avoiding airflow dead zones caused by membrane overlap and ensuring stable nitrogen-oxygen separation efficiency. The hollow fiber membrane bundles increase the contact area with external air through the porous upper and lower fiber membrane covers. The hollow fiber membrane is made of a polyethersulfone-like material, whose molecular sieving properties allow oxygen molecules to diffuse faster than nitrogen molecules.

[0065] To prevent the oxygen generator assembly 200 from shifting during transportation or vibration, which could create gaps between the oxygen generator assembly 200 and the edge of the volute cover and affect oxygen separation efficiency, while also ensuring easy disassembly of the oxygen generator assembly 200, an oxygen-enriched membrane fixing bracket (second body) is designed to secure the oxygen generator assembly 200. The bracket features locking mechanisms where claws engage with the protrusions of the air inlet connector, and notches engage with the positioning protrusions of the volute cover (e.g.,...). Figure 2 , Figure 6 (As shown). Utilizing the spatial layout of the fresh air components, the oxygen generating unit 200 is installed between the volute cover and the sealing cover (as shown). Figure 4 , Figure 5 As shown in the figure, the volute cover and the sealing cover are connected by a screw post and a snap-fit ​​structure, reducing the need for bolt connections.

[0066] The working process of the device can be roughly divided into the following four parts: 1. Air intake stage: Air enters the oxygen generating unit through the air inlet. After particulate matter is removed by the filter, the air is drawn towards the oxygen generating component 200 by the internal negative pressure created by the rotation of the ventilation fan. 2. Separation stage: Air comes into contact with the hollow fiber membrane bundle through the holes in the fiber membrane cover. Oxygen diffuses into the inner side of the membrane, while nitrogen is trapped on the outer side. Nitrogen and oxygen are separated by the difference in the separation rate of nitrogen and oxygen molecules entering the hollow fiber membrane. 3. Oxygen exhaust stage: The separated oxygen is discharged through the air outlet on the exhaust cover. To improve the air circulation speed and prevent oxygen from entering the inner side of the hollow fiber membrane and not diffused back to the outer side, an external air compressor or vacuum pump is used to extract the oxygen in time, maintaining the oxygen concentration inside the membrane lower than the oxygen concentration outside the membrane, thereby achieving unidirectional diffusion and accelerating the oxygen separation efficiency. 4. Nitrogen exhaust stage: The remaining air, which is mainly composed of nitrogen and has not passed through the hollow fiber membrane, is discharged to the outside through the air outlet of the volute under the force of the ventilation fan. This completes the entire process of oxygen enrichment and nitrogen exhaust.

[0067] The following technical problems are solved by this application:

[0068] Traditional fresh air conditioners only exchange air by introducing fresh outside air, but the oxygen concentration in the outside air is similar to that indoors, so they cannot significantly increase the indoor oxygen content. As people breathe and metabolize, the indoor oxygen concentration continues to decline and remains lower than the outside level, failing to effectively improve the "stuffy" feeling and limiting the user's health and comfort.

[0069] Oxygen diffuses into the inner side of the hollow fiber membrane and then easily diffuses back to the outer side, affecting the oxygen separation efficiency.

[0070] In hollow fiber membrane oxygen generation technology, the small contact area between the membrane and air results in a slow oxygen passage rate, leading to low nitrogen-oxygen separation efficiency.

[0071] Standalone oxygen generators require additional ductwork, motors, and space, making them inefficiently integrated with existing fresh air conditioning systems (such as volutes and filters). This not only increases the internal space occupied by the equipment but also raises manufacturing costs and installation complexity.

[0072] The oxygen generator assembly 200 is prone to displacement during transportation, installation, or use, creating gaps between it and the edge of the volute cover, thus compromising the seal. This reduces nitrogen-oxygen separation efficiency and affects the stability of oxygen-enriched air output.

[0073] As can be seen from the above description, the embodiments of this application achieve the following technical effects:

[0074] This application focuses on high efficiency, stability, and integration. By designing an oxygen generation device, it achieves an increase in indoor oxygen concentration while taking into account economy and user experience, thus solving the technical bottleneck of traditional fresh air conditioners in the field of healthy breathing.

[0075] High efficiency and stability: Utilizing hollow fiber membrane separation technology, oxygen-enriched air is directly delivered into the room, rather than relying solely on external air exchange. Maintaining the oxygen concentration gradient across the membrane through positive and negative pressure ensures that oxygen does not diffuse backwards, thus accelerating the oxygen production efficiency.

[0076] Equipment integration: The oxygen generating component 200 is integrated between the volute cover and the sealing cover of the fresh air component, utilizing the existing fan power source, air duct and filter structure.

[0077] Mechanical fixing: The oxygen generator fixing frame and buckle structure are designed to prevent the membrane module from shifting during transportation or vibration, and to ensure a seamless seal with the volute cover.
