Technical Field
[0001] This utility model relates to the field of oxygen generation and air conditioning technology, specifically to an oxygen generation device and an air conditioner having the same. Background Technology
[0002] In the current air conditioning technology field, fresh air conditioning systems are widely used to improve indoor air quality, especially in enclosed or semi-enclosed environments, where they can effectively introduce fresh air. However, these systems generally lack the function of increasing indoor oxygen concentration. With the increasing awareness of health, oxygen-generating air conditioners are gradually gaining market attention because they can create a slightly oxygen-rich indoor environment, thereby improving breathing comfort and benefiting health.
[0003] However, oxygen generating modules have strict requirements for the purity of incoming air, so air filters are usually installed before the air enters the oxygen generating module to remove particulate matter and other impurities from the air.
[0004] To save indoor installation space, existing oxygen-generating air conditioners typically place the oxygen-generating components in the outdoor unit. When the filter is installed outdoors, it can directly intercept particulate matter in the outside air and filter out impurities in the outdoor air.
[0005] However, due to prolonged exposure to outdoor environments, the filter is prone to contamination and clogging, especially in dusty environments, which seriously affects the filter's lifespan and oxygen production efficiency. Utility Model Content

[0013] Furthermore, the connecting part also includes a connecting body, which is annular and disposed at the end of the filter body, with each tooth groove disposed on the inner wall of the connecting body.
[0014] Furthermore, the filter body has a cylindrical structure, and the filter assembly also includes: a top cover, which is located at the top of the filter body, and the side circumferential surface of the top cover is in contact with the inner wall of the filter body; and a bottom plate, which is located at the bottom of the filter body, and the bottom plate is provided with an exhaust port and an air inlet port, the exhaust port being connected to an air passage, and the air inlet port being connected to a nitrogen passage.
[0015] Furthermore, the filter assembly also includes a baffle, which is mounted on the filter body and connected to the top cover.
[0016] According to another aspect of the present invention, an air conditioner is provided, including an outdoor unit and an oxygen generating device, wherein at least a portion of the oxygen generating device is disposed within the outdoor unit, and the oxygen generating device is the oxygen generating device described above.
[0017] According to the technical solution of this utility model, the oxygen generating equipment includes: an oxygen generating component, which includes an air intake pipe and a nitrogen exhaust pipe; and a filter component, which includes a filter body, which has an air channel and a nitrogen channel.

[0037] 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.
[0038] As mentioned in the background section, existing oxygen-generating air conditioning systems widely utilize molecular sieve technology for oxygen separation and enrichment. These systems allow outdoor air to enter the oxygen-generating module, which then delivers the produced oxygen indoors, improving indoor air quality. However, the oxygen-generating module has strict requirements for the purity of the incoming air; therefore, an air filter is typically installed before the air enters the module to remove particulate matter and other impurities. Currently, there are two main options for the installation location of the air filter: outdoors or indoors. When the filter is installed outdoors, although it can directly intercept particulate matter in the outside air, prolonged exposure to the outdoor environment makes the filter prone to contamination and clogging, especially in dusty environments, significantly shortening its lifespan. Therefore, to address the aforementioned technical problems, the oxygen generating equipment provided in this application includes an oxygen generating component 100 and a filter component 200. The oxygen generating component 100 includes an air intake pipe 110 and a nitrogen exhaust pipe 120. The filter component 200 includes a filter body 210, within which an air channel 211 and a nitrogen channel 212 are provided. The air channel 211 communicates with the air intake pipe 110, and the nitrogen channel 212 communicates with the nitrogen exhaust pipe 120. The filter body 210 is rotatably arranged around a predetermined axis so that, during the process of nitrogen in the nitrogen channel 212 being discharged through the filter body 210, nitrogen is used to purge the filter body 210. By providing two non-communicating airflow channels within the filter body, independent processing of air and nitrogen is ensured, mutual interference is avoided, the stability and reliability of the entire system are enhanced, and the risk of cross-contamination of gases is reduced. By designing the filter assembly directly near the oxygen generator, the high-pressure nitrogen gas generated during oxygen production effectively cleans the filter body, preventing the accumulation of dust and particulate matter on the filter screen due to long-term use. This significantly extends the filter screen's lifespan, reduces maintenance costs, and decreases the frequency of filter replacements. The automatic rotation mechanism of the filter body, combined with the high-pressure nitrogen spray, enables the filter screen to self-clean without additional manual intervention or specialized cleaning equipment. This simplifies the operation process, enhances the system's automation level, and greatly extends the lifespan of the filter assembly.
[0039] Please refer to Figures 1 to 7This application provides an oxygen generating device, including: an oxygen generating component 100, which includes an air intake pipe 110 and a nitrogen exhaust pipe 120; and a filter component 200, which includes a filter body 210, in which an air channel 211 and a nitrogen channel 212 are provided, the air channel 211 being connected to the air intake pipe 110 and the nitrogen channel 212 being connected to the nitrogen exhaust pipe 120; the filter body 210 is rotatably arranged around a predetermined axis so that when nitrogen in the nitrogen channel 212 is discharged through the filter body 210, nitrogen is used to purge the filter body 210.
[0040] The oxygen generating module 100 and the filter module 200 are tightly integrated together. The oxygen generating module includes an air intake pipe 110 and a nitrogen exhaust pipe 120. The air intake pipe 110 is responsible for introducing outside air into the oxygen generating module. After being processed by oxygen generation technologies such as molecular sieves, oxygen is delivered into the room through the oxygen pipe, while nitrogen is discharged through the nitrogen exhaust pipe 120.
[0041] The filter body 210 has two non-communicating channels: an air channel 211 and a nitrogen channel 212. The air channel 211 is connected to the air intake pipe 110, while the nitrogen channel 212 is connected to the nitrogen exhaust pipe 120. The filter body 210 is rotatable around a predetermined axis. Utilizing the high-pressure nitrogen generated during the oxygen production process, when the nitrogen in the nitrogen channel 212 passes through the filter body 210, the high-pressure spraying action of the nitrogen can remove dust and particulate matter accumulated on the outside of the filter body.
[0042] The baffle 220 inside the filter body 210 precisely divides the internal space into air channels and nitrogen channels, ensuring independent flow of air and nitrogen inside the filter body, avoiding airflow mixing, optimizing airflow path, and improving filtration efficiency and self-cleaning performance.
[0043] The filter body 210 has the ability to rotate around a predetermined axis. Combined with the high-pressure nitrogen injection in the nitrogen channel 212, it can regularly clean the surface of the filter screen, effectively prevent dust accumulation, and extend the service life of the filter screen.
[0044] Specifically, the filter assembly 200 also includes: Figures 3 to 5 As shown, a partition 220 is disposed inside the filter body 210. The two ends of the partition 220 are respectively attached to the inner wall of the filter body 210 to divide the filter body 210 into an air channel 211 and a nitrogen channel 212.
[0045] The baffle 220 ensures that the flow of air and nitrogen inside the filter body 210 is effectively separated and guided. Air can only enter through the air channel 211, while nitrogen flows through the nitrogen channel 212. This precise airflow guidance avoids gas mixing and ensures that the purity of oxygen is not affected.
[0046] The presence of baffle 220 allows high-pressure nitrogen to form a more concentrated and directional airflow in the nitrogen channel. When the nitrogen passes through the filter body in the reverse direction, it can more effectively remove fine dust and particles that are difficult to remove from the filter screen, improve the effect of the self-cleaning mechanism, and ensure the continuous and efficient operation of the filter screen.
[0047] The partition 220 includes a first plate 221 and a second plate 222 that are connected to each other, with the first plate 221 and the second plate 222 arranged at an acute angle, and a nitrogen channel 212 located between the first plate 221, the second plate 222 and the filter body 210.
[0048] The acute angle between the first plate 221 and the second plate 222 creates a compact and efficient space, allowing for a more concentrated spraying force of high-pressure nitrogen. The nitrogen channel 212 is located within this area enclosed by the two plates and the filter body 210. This design makes the flow path of the nitrogen more precise, enabling it to be directly aimed at the surface of the filter body and enhancing the cleaning effect.
[0049] The nitrogen channel 212 makes full use of the three-dimensional structure formed by the first plate 221 and the second plate 222 to ensure that nitrogen can flow in a specific direction under high pressure, effectively sweeping the surface of the filter body and removing accumulated dust and particulate matter.
[0050] Combining the rotatable design of the filter body 210, when the oxygen generator enters self-cleaning mode, the filter body begins to rotate. The acute angle structure between the first plate 221 and the second plate 222 ensures that each part of the filter screen receives uniform cleaning from high-pressure nitrogen. This mechanism... Figure 5 The advantages of dynamic cleaning are clearly demonstrated in the process.
[0051] Furthermore, the partition 220 also includes: a first bonding plate 223, disposed at the end of the first plate 221 away from the second plate 222, the first bonding plate 223 being bonded to the inner wall of the filter body 210; and a second bonding plate 224, disposed at the end of the second plate 222 away from the first plate 221, the second bonding plate 224 being bonded to the inner wall of the filter body 210; wherein the first plate 221, the second plate 222, the first bonding plate 223, and the second bonding plate 224 are integrally formed structures.
[0052] The first bonding plate 223 and the second bonding plate 224 can increase the bonding area between the partition 220 and the filter body 210, thereby forming an effective seal between the partition 220 and the filter body 210, and preventing the airflow in the air channel 211 and the nitrogen channel 212 from interfering with each other.
[0053] The increased contact area between the first bonding plate 223 and the second bonding plate 224 and the inner wall of the filter body 210 significantly enhances the sealing effect between the two channels. This means that the airflow in the air channel 211 and the nitrogen channel 212 is more effectively isolated, avoiding any possible cross-interference and ensuring the purity of the gas treatment, especially the high requirements in the oxygen production process.
[0054] Thanks to the enhanced airflow isolation, the flow of air and nitrogen within the filter unit is more orderly, reducing energy loss. In oxygen generation mode, air flows through the filter undisturbed, maintaining high-efficiency oxygen separation; while in self-cleaning mode, high-pressure nitrogen precisely sprays and cleans the filter, improving cleaning effectiveness and ensuring equipment operating efficiency.
[0055] The one-piece molded partition structure reduces gaps and interfaces inside the equipment, lowers the chance of dust and impurities accumulating, and simplifies daily maintenance and cleaning.
[0056] In the embodiments provided in this application, such as Figure 2 As shown, the filter body 210 is provided with a connecting part 230, and the filter assembly 200 further includes a driving component 240, which is drivenly connected to the connecting part 230. The driving component 240 drives the filter body 210 to rotate through the connecting part 230.
[0057] The drive unit 240 precisely controls the rotation of the filter body 210 via the connecting part 230, and combined with the spraying of high-pressure nitrogen, achieves a thorough cleaning of the filter screen surface. This mechanism ensures that the filter screen can regularly remove accumulated dust and particles, thereby greatly extending the service life of the filter screen and reducing the frequency of maintenance.
[0058] The design of the connection part 230 makes energy transmission more efficient and reduces energy loss during transmission. The drive component 240 can accurately and effectively transmit power to the filter body, ensuring the energy utilization efficiency of the self-cleaning process and reducing overall energy consumption.
[0059] Through the connecting part 230, the drive component 240 can precisely control the rotation speed and rotation angle of the filter body, ensuring complete automation of the cleaning process.
[0060] Furthermore, the connecting part 230 is disposed at the end of the filter body 210. The connecting part 230 includes a plurality of toothed grooves 231, which are arranged sequentially along the circumferential direction of the filter body 210. The driving component 240 includes a driving gear 241, which is rotatably disposed around its own axis. The driving gear 241 meshes with each toothed groove 231 to drive the filter body 210 to rotate during rotation.
[0061] The precise meshing of the multiple grooves 231 on the connecting part 230 with the drive gear 241 ensures stable and precise rotation of the filter body 210. This allows the oxygen generator to accurately control the rotation angle and speed of the filter body according to a preset program or sensor signals, thereby optimizing the self-cleaning effect and frequency.
[0062] The design of the toothed groove 231 maximizes the power transmission efficiency of the drive gear 241 and reduces energy loss during power transmission. Compared to smooth surface contact, the meshing of the toothed groove and gear provides a more reliable rotational driving force, especially when under load or encountering resistance, ensuring the normal rotation of the filter body.
[0063] In the specific implementation process, the connecting part 230 also includes a connecting body 232, which is annular and is located at the end of the filter body 210. Each tooth groove 231 is located on the inner wall of the connecting body 232.
[0064] The design of the annular connecting body 232 strengthens the connection between the filter body and the baffle, reduces structural loosening caused by vibration or external impact during equipment operation, and improves the stability and reliability of the entire equipment.
[0065] The precise meshing of the toothed groove 231 with the motor-driven gear ensures smooth and accurate rotation of the filter body in self-cleaning mode. This design allows the filter body to be evenly sprayed with high-pressure nitrogen during rotation, avoiding cleaning dead zones and improving cleaning efficiency.
[0066] Specifically, the filter body 210 has a cylindrical structure, and the filter assembly 200 also includes: a top cover 250, which is disposed at the top of the filter body 210, and the side circumferential surface of the top cover 250 is in contact with the inner wall of the filter body 210; and a bottom plate 260, which is disposed at the bottom of the filter body 210, and the bottom plate 260 is provided with an exhaust port 261 and an air inlet port 262, the exhaust port 261 being connected to the air passage 211, and the air inlet port 262 being connected to the nitrogen passage 212.
[0067] The tight fit between the top cover 250 and the inner wall of the filter body 210, along with the precise connection between the exhaust port 261 and the air inlet port 262 on the base plate 260 and their corresponding channels, together constitute a highly sealed system. This enhanced sealing ensures that the airflow in the air channel 211 and the nitrogen channel 212 will not leak, maintaining their independence and improving the purity and efficiency of gas treatment.
[0068] The exhaust port 261 and air inlet port 262 on the base plate 260 are connected to the air passage 211 and nitrogen passage 212 respectively, realizing directional control of airflow and ensuring smooth airflow during the filtration process and effective nitrogen spraying during the self-cleaning process. This design avoids unnecessary airflow backflow or leakage, thereby improving the working efficiency of the entire filter assembly.
[0069] The top cover 250 and bottom plate 260 enhance the overall structural stability of the filter assembly, reduce vibration and noise during equipment operation, and improve the user experience. At the same time, the stable structural design also helps extend the equipment's lifespan and reduce the frequency of maintenance due to structural loosening or damage.
[0070] The filter assembly 200 also includes a baffle 270, which covers the filter body 210 and is connected to the top cover 250.
[0071] The baffle 270 effectively guides the airflow path, ensuring that air and nitrogen are precisely processed within the filter assembly via air channel 211 and nitrogen channel 212, respectively. Simultaneously, the connection between the baffle and the top cover further enhances the isolation between the two channels, preventing cross-contamination between air and nitrogen within the filter body and maintaining the purity of the processed gas.
[0072] The connection between the baffle 270 and the top cover 250 forms a sealed top structure, enhancing the overall sealing performance of the filter assembly. This design reduces interference from the external environment on the filtration process, ensuring filtration efficiency, while also preventing gas leakage during oxygen production and improving the safety of equipment operation.
[0073] Preferably, the drive component 240 further includes a drive motor 242, which is locked onto the base plate 260 by a first screw 243. The drive shaft of the drive motor 242 is drivenly connected to the drive gear 241. The baffle 270 is locked onto the top cover 250 by a second screw 272. A washer 271 is also provided between the second screw 272 and the baffle 270.
[0074] The drive motor is securely fixed to the base plate 260 by the first screw 243, ensuring a stable position of the motor during the operation of the oxygen generator and reducing transmission efficiency loss due to vibration or loosening. The precise connection between the motor drive shaft and the drive gear 241 ensures high efficiency of power transmission and accurate rotation control, enhancing the rotational stability and cleaning effect of the filter body 210 during the self-cleaning process.
[0075] The combined use of the second screw 272 and the washer 271 not only ensures a tight connection between the baffle 270 and the top cover 250, but also provides additional airtightness and shock absorption through the washer. The presence of the washer 271 can compensate for the small gaps between components caused by manufacturing tolerances or long-term operation, maintain the sealing of the filter components, and absorb vibrations during equipment operation, reduce noise generation, and improve the overall stability of operation.
[0076] This application also provides an air conditioner, including an outdoor unit 300 and an oxygen generating device, at least part of which is disposed inside the outdoor unit 300, and the oxygen generating device is the oxygen generating device of the above embodiment.
[0077] By tightly integrating the oxygen generator with the outdoor unit and utilizing the reverse spraying of high-pressure nitrogen, highly efficient self-cleaning of the filter assembly is achieved. This eliminates the need for manual maintenance of the filter, reducing repair costs and downtime, while ensuring continuous and efficient operation of the air conditioner under different seasons and environmental conditions.
[0078] The air conditioner of this application includes an oxygen generating device, an air filtration device, an air particulate matter detection device, and an air flow detection device. The oxygen generating device, the air filtration device, the air particulate matter detection device, and the air flow detection device are all installed inside the outdoor unit 300.
[0079] The filter assembly 200 has two separate channels. One channel connects to the outside and the air compressor of the oxygen generator assembly 100, through which air is filtered by passing through the air channel 211 and the filter screen. The nitrogen channel 212 connects to the outside and the nitrogen outlet of the oxygen generator assembly 100, through which the high-pressure nitrogen generated by the oxygen generator assembly 100 passes through the nitrogen channel 212 and the filter screen and is discharged to the outside. The high-pressure nitrogen airflow cleans the dust on the filter screen.
[0080] The filter assembly 200 is fitted around the outer ring of the partition 220. A baffle 270 is fixed to one side of the partition 220 by a second screw 272 and a washer 271, restricting the left-right movement of the filter body 210. On the other side of the partition 220, a motor is fixed via a base plate 260. A gear is fitted onto the motor shaft, and the gear engages with the connection part 230 of the filter assembly. When the motor rotates, the gear drives the filter screen to rotate (e.g., ...). Figure 2 (as shown);
[0081] Air passes through an air filtration system, where dust particles are trapped by the filter screen and remain on the outer ring of the filter assembly. Once the oxygen concentrator starts, it continuously discharges high-pressure nitrogen gas. This high-pressure nitrogen flows through the air duct components and from the inside of the filter assembly to the outside. Under the impact of the high-pressure gas, the dust particles remaining on the outer ring of the filter assembly are separated from the filter assembly. (e.g.) Figure 2 (as shown);
[0082] When the air conditioner starts its oxygen production function, after h hours, it enters the self-cleaning mode of the air filter. The motor rotates once, causing the filter assembly to rotate 60° for 5 minutes. High-pressure nitrogen is used to clean the dust in 1 / 6 of the filter area. The motor then rotates once more, causing the filter assembly to rotate 60° for 5 minutes. This process is repeated 6 times to clean the dust around the filter assembly in 360°. After cleaning once, the self-cleaning mode of the air filter is exited.
[0083] The filter assembly consists of a filter body 210 and an internal gear, and can be fixed with glue or double-sided tape.
[0084] like Figure 8 As shown, the oxygen generating equipment also includes a gas storage tank 410, a molecular sieve 420, a solenoid valve 430, a silencer 440, an air compressor 450, a radiator 460, and a one-way valve 470. The molecular sieve 420 includes two sieve bodies. One sieve body is used to connect with the air compressor 450 to filter out oxygen, and the other sieve body is used to filter out nitrogen and is connected to the nitrogen channel 212. A solenoid valve 430 is installed between the molecular sieve 420 and the oxygen and nitrogen channels. A silencer 440 is installed on the nitrogen discharge pipeline to reduce noise during the nitrogen discharge process. The air compressor 450 is also connected to the radiator 460 to dissipate heat from the air compressor 450. Furthermore, a one-way valve 470 is installed between the gas storage tank 410 and the molecular sieve 420 to allow the separated oxygen to flow unidirectionally into the gas storage tank 410, while the nitrogen flows unidirectionally into the nitrogen channel 212 and is discharged.
[0085] As can be seen from the above description, the embodiments of this utility model achieve the following technical effects:
[0086] This application provides an oxygen generating device, including: an oxygen generating component 100, which includes an air intake pipe 110 and a nitrogen exhaust pipe 120; and a filter component 200, which includes a filter body 210, in which an air channel 211 and a nitrogen channel 212 are provided, the air channel 211 being connected to the air intake pipe 110 and the nitrogen channel 212 being connected to the nitrogen exhaust pipe 120; the filter body 210 is rotatably arranged around a predetermined axis so that, during the process of nitrogen in the nitrogen channel 212 being discharged through the filter body 210, the filter body 210 is purged with nitrogen.
[0087] The oxygen generating module 100 and the filter module 200 are tightly integrated together. The oxygen generating module includes an air intake pipe 110 and a nitrogen exhaust pipe 120. The air intake pipe 110 is responsible for introducing outside air into the oxygen generating module. After being processed by oxygen generation technologies such as molecular sieves, oxygen is delivered into the room through the oxygen pipe, while nitrogen is discharged through the nitrogen exhaust pipe 120.
[0088] The filter body 210 has two non-communicating channels: an air channel 211 and a nitrogen channel 212. The air channel 211 is connected to the air intake pipe 110, while the nitrogen channel 212 is connected to the nitrogen exhaust pipe 120. The filter body 210 is rotatable around a predetermined axis. Utilizing the high-pressure nitrogen generated during the oxygen production process, when the nitrogen in the nitrogen channel 212 passes through the filter body 210, the high-pressure spraying action of the nitrogen can remove dust and particulate matter accumulated on the outside of the filter body.
[0089] The baffle 220 inside the filter body 210 precisely divides the internal space into air channels and nitrogen channels, ensuring independent flow of air and nitrogen inside the filter body, avoiding airflow mixing, optimizing airflow path, and improving filtration efficiency and self-cleaning performance.
[0090] The filter body 210 has the ability to rotate around a predetermined axis. Combined with the high-pressure nitrogen injection in the nitrogen channel 212, it can regularly clean the surface of the filter screen, effectively prevent dust accumulation, and extend the service life of the filter screen.
[0091] It should be noted that the terminology used herein is for the purpose of describing particular embodiments only and is not intended to limit the exemplary embodiments according to this application. As used herein, the singular form is intended to include the plural form as well, unless the context clearly indicates otherwise.

[0092] Unless otherwise specifically stated, the relative arrangement, numerical expressions, and values of the components and steps described in these embodiments do not limit the scope of this application. It should also be understood that, for ease of description, the dimensions of the various parts shown in the drawings are not drawn to actual scale. Techniques, methods, and devices known to those skilled in the art may not be discussed in detail, but where appropriate, such techniques, methods, and devices should be considered part of the specification. In all examples shown and discussed herein, any specific values should be interpreted as merely exemplary and not as limitations. Therefore, other examples of exemplary embodiments may have different values. It should be noted that similar reference numerals and letters in the following drawings denote similar items; therefore, once an item is defined in one drawing, it need not be further discussed in subsequent drawings.
[0093] For ease of description, spatial relative terms such as "above," "on top of," "on the upper surface of," "above," etc., are used herein to describe the spatial positional relationship of a device or feature as shown in the figures to other devices or features. It should be understood that spatial relative terms are intended to encompass different orientations in use or operation beyond the orientation of the device as described in the figures. For example, if the device in the figures were inverted, a device described as "above" or "on top of" other devices or structures would subsequently be positioned as "below" or "under" other devices or structures. Thus, the exemplary term "above" can include both "above" and "below." The device may also be positioned in other different ways (rotated 90 degrees or in other orientations), and the spatial relative descriptions used herein will be interpreted accordingly.
[0094] It should be noted that the terminology used herein is for the purpose of describing particular embodiments only and is not intended to limit the exemplary embodiments according to this application.
