Existing technologies generally categorize oxygen-generating air conditioning solutions into four types based on the distribution of filtration and oxygen generation devices: indoor oxygen generation with filtration, indoor oxygen generation with outdoor filtration, outdoor oxygen generation with indoor filtration, and outdoor oxygen generation with filtration. Due to the high noise levels associated with oxygen generation, outdoor oxygen generation is the most common solution, with varying filtration devices.

[0030] It should be noted that, in the absence of conflict, the embodiments and features of the embodiments in this application can be combined with each other. The present invention will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0031] In order to solve the problem of short outdoor service life of an oxygen-generating filter device of an oxygen-generating air conditioner in the prior art, the present invention provides a filter device, an air-conditioning outdoor unit and an oxygen-generating air conditioner.

[0032] Please refer to Figures 1 to 7As shown, one aspect of the technical solution of the present invention provides a filtering device, including a support seat 10, a filter assembly 30, a fan blade assembly 50 and a cleaning assembly 40; a connecting port 11 is provided on the support seat 10; the filter assembly 30 is provided on the support seat 10, and the filter assembly 30 includes a rotatably arranged filter component 31; the fan blade assembly 50 is rotatably provided on the support seat 10, and at least a part of the fan blade assembly 50 is located at the connecting port 11, so that the airflow flowing through the connecting port 11 drives the fan blade assembly 50 to rotate; the fan blade assembly 50 is transmission-connected to the filter component 31, so that the fan blade assembly 50 drives the filter component 31 to rotate during the rotation process; the cleaning assembly 40 is provided on the support seat 10, and the cleaning assembly 40 is located on one side of the filter component 31 and contacts the outer peripheral wall of the filter component 31, so that when the filter component 31 rotates, the dust on the outer peripheral wall of the filter component 31 is cleaned by the cleaning assembly 40.

[0033] The filter device of the present invention is a technical solution of the first embodiment. By designing the transmission connection between the fan blade assembly 50 and the filter component 31, when airflow through the communication port 11 drives the fan blade assembly 50 to rotate, the fan blade assembly 50 can further drive the filter component 31 to rotate. This allows the filter component 31 to automatically remove dust accumulated on its outer peripheral wall while operating normally, thereby avoiding the problem of reduced filtration efficiency due to dust blockage, maintaining the stability and efficiency of the filtration performance, and further solving the problem of the short outdoor service life of oxygen-generating filter devices in oxygen-generating air conditioners in the prior art. It effectively prevents the premature damage of the filter component 31 due to long-term dust accumulation, thereby greatly extending the service life of the filter component 31 and reducing maintenance and replacement costs.

[0034] Specifically, the fan assembly 50 includes a rotating shaft 51, a rotating fan blade 52, and a first gear 53; the rotating shaft 51 is rotatably mounted on the support base 10; the rotating fan blade 52 is mounted on the rotating fan blade 52 and is located at the connecting port 11; the first gear 53 is mounted on the rotating shaft 51, and the filter component 31 is provided with a second gear 32. The first gear 53 and the second gear 32 engage with each other so that the rotating shaft 51 drives the filter component 31 to rotate via the first gear 53 during rotation. In this way, the precise engagement of the first gear 53 on the rotating shaft 51 with the second gear 32 on the filter component 31 ensures that after the airflow flowing through the connecting port 11 drives the rotating fan blade 52 to rotate, the fan assembly 50 transmits power to the filter component 31 via the first gear 53, driving the filter component 31 to rotate and self-clean. This achieves efficient self-cleaning of the filter component 31 driven by the airflow, not only extending the service life of the filter component 31 but also simplifying the maintenance process.

[0035] In this embodiment, the first gear 53 is a partial gear, comprising a wheel body 530 and a plurality of tooth segments 531. The wheel body 530 is disposed on the rotating shaft 51. The plurality of tooth segments 531 are sequentially spaced along the circumference of the wheel body 530, and each of the plurality of tooth segments 531 is configured to mesh with the second gear 32. This arrangement, by providing the plurality of tooth segments 531 spaced apart on the wheel body 530 rather than a continuous ring gear, reduces the time that the first gear 53 and the second gear 32 are continuously meshed. As the airflow drives the fan assembly 50 to rotate, the distribution of the plurality of tooth segments 531 reduces the rotational speed and frequency of the filter component 31, allowing the cleaning assembly 40 to fully clean the filter component 31, ensuring effective cleaning while also preventing excessive wear.

[0036] Specifically, the filter component 31 is a drum-type filter, comprising a filter element 33 and two end caps 34. The filter element 33 comprises a first filter 330, a second filter 331, and a third filter 332, stacked in the direction of air flow. The two end caps 34 are connected to the ends of the filter element 33, respectively. The support base 10 is provided with two brackets 35, each of which is rotatably connected to the two brackets 35. The first filter 330 is an injection-molded part integrally formed with the filter, located at the outermost layer to filter out larger dust and impurities in the air. The second filter 331 is located in the middle and filters out PM10 dust particles. The third filter 332 is located in the innermost layer and filters out PM2.5 dust particles. Air is filtered layer by layer through the first filter 330, the second filter 331, and the third filter 332, significantly improving filtration efficiency and air purification effectiveness, and greatly extending the service life of the filters.

[0037] To clean the filter element 31, the cleaning assembly 40 includes a brush element 41. The brush element 41 is positioned on the support base 10 along the extension direction of the filter element 31. The brush element 41 has bristles on the side facing the filter element 31, and the bristles contact the outer peripheral wall of the filter element 31. Thus, when the filter element 31 rotates, the bristles can effectively remove dust and impurities adhering to the outer peripheral wall, thereby achieving self-cleaning of the filter element 31 and keeping the filter element 31 clean, thereby maintaining its good filtering performance and extending its service life.

[0038] Specifically, the brush component 41 is provided with a plurality of avoidance grooves 410 spaced along its extension direction for avoiding the plurality of protrusions on the outer peripheral wall of the filter component 31. The protrusions refer to the second gear 32 provided on the filter component 31. This ensures that the bristles do not come into hard contact with the protrusions on the filter component 31 during the cleaning process, thereby avoiding unnecessary wear.

[0039] Specifically, the support base 10 is provided with a plurality of through holes 12, so that dust swept from the outer peripheral wall of the filter element 31 can be discharged through the plurality of through holes 12. In this way, by promptly and evenly discharging the swept dust and impurities from around the filter element 31, dust accumulation on the support base 10 is avoided, and the surface around the filter element 31 is kept clean.

[0040] According to another aspect of the present invention, an air-conditioning outdoor unit is provided, comprising the above-mentioned filter device, an outer housing 1 and an axial flow fan blade 2; the outer housing 1 has a shell cavity, a support seat 10 of the filter device is arranged on the top of the outer housing 1, and a connecting port 11 and a plurality of through holes 12 on the support seat 10 are respectively connected to the shell cavity; the axial flow fan blade 2 is arranged in the shell cavity, so that when the air-conditioning outdoor unit is in operation, the axial flow fan blade 2 rotates, so that the axial flow fan blade 2 drives the rotating fan blade 52 to rotate during the rotation process and discharges the dust falling from the plurality of through holes 12 out of the shell cavity.

[0041] In this embodiment, the meshing structure between the first gear 53 and the second gear 32 of the fan assembly 50 itself has a certain friction resistance. The resistance can be further increased in the design so that the rotating fan 52 can be driven to rotate only when the rotation speed of the axial flow fan 2 is higher than 750 rpm. In addition, the first gear 53, which is an incomplete gear, can reduce the rotation speed of the filter component 31, so that the brush component 41 can fully clean the first filter 330.

[0042] Specifically, the air conditioner outdoor unit also includes an air compressor assembly 20, an air intake silencer assembly 60 and a molecular sieve oxygen production assembly 70. The air compressor assembly 20, the air intake silencer assembly 60 and the molecular sieve oxygen production assembly 70 are respectively arranged on the support base 10. The air compressor assembly 20 has an air inlet and an air outlet. The air intake silencer assembly 60 is respectively connected to the filter component 31 and the air inlet of the air compressor assembly 20, and the molecular sieve oxygen production assembly 70 is connected to the air outlet of the air compressor assembly 20.

[0043] Usage process: After the molecular sieve oxygen production component 70 is started, the air compressor component 20 runs to provide power to draw air in. In this process, the air on the outside of the filter component 31 enters it under the drive of suction, passes through the first filter 330, the second filter 331, and the third filter 332 in sequence, and then enters the intake pipe from the middle cavity, and then enters the air intake silencer component 60 and then enters the air compressor component 20. After the air compressor component 20 works, the air enters the molecular sieve oxygen production component 70.

[0044] In the first embodiment of the filter device of the present invention, the self-cleaning operation mode of the filter element 31 is:

[0045] When the air conditioner outdoor unit is in operation, the axial flow impellers 2 rotate, driving air flow. The rotating impellers 52 in the impeller assembly 50 are located within the air flow area and are driven to rotate together. This, in turn, drives the first gear 53, which has incomplete gears on both sides, to rotate together via the rotating shaft 51. The incomplete gears mesh with the second gear 32 on the filter component 31, driving the second gear 32 to rotate, thereby driving the entire filter component 31 to rotate together. At this time, the brush component 41 mounted on the support base 10 contacts the first filter 330, sweeping dust and impurities from the first filter 330 and dropping them onto the support base 10. Through the multiple through-holes 12 on the support base 10, as the axial flow impellers 2 rotate, the air flows, driving the dust and impurities out of the air conditioner outdoor unit.

[0046] In the second embodiment of the filtering device of the present invention, the fan blade assembly 50 only includes a rotating fan blade 52, which is coaxially connected to the filter component 31 and is located at one end of the filter component 31. The molecular sieve oxygen production assembly 70 has an exhaust pipe 71 for discharging high-pressure nitrogen. The exhaust port of the exhaust pipe 71 is set toward the rotating fan blade 52 so that the rotating fan blade 52 can be driven to rotate under the flow of high-pressure nitrogen.

[0047] In the second embodiment of the filter device of the present invention, please refer to Figures 8 to 10 As shown, the self-cleaning operation mode of the filter element 31:

[0048] When the molecular sieve oxygen generator assembly 70 is in operation, air passes through the drum filter and then enters the air compressor assembly 20, the air intake silencer assembly 60, and the molecular sieve oxygen generator assembly 70. Finally, the molecular sieve oxygen generator assembly 70 discharges high-pressure nitrogen, which is discharged through the exhaust pipe 71. The rotary fan blades 52 are located at the exhaust port of the exhaust pipe 71. As the high-pressure nitrogen is discharged, the rotary fan blades 52 are driven to rotate, thereby driving the drum filter coaxially connected to the rotary fan blades 52 to rotate together. At this time, the brush component 41 installed on the support base 10 contacts the first filter 330 to sweep dust and impurities on the first filter 330 and drop them onto the support base 10. Through the multiple through holes 12 on the support base 10, the air flows under the rotation of the axial flow fan blades 2, driving the dust and impurities out of the air conditioner outdoor unit.

[0049] According to another aspect of the present invention, an oxygen-generating air conditioner is provided, comprising the above-mentioned air conditioner outdoor unit and air conditioner indoor unit.

The technical solution of the present invention, through the design of the transmission connection between the fan blade assembly 50 and the filter component 31, allows the fan blade assembly 50 to rotate when airflow passes through the communication port 11, and the fan blade assembly 50 can further drive the filter component 31 to rotate. This allows the filter component 31 to automatically remove dust accumulated on its outer peripheral wall while operating normally, thereby avoiding the problem of reduced filtration efficiency due to dust blockage, maintaining the stability and efficiency of the filtration performance, and further solving the problem of the short service life of the oxygen filter device of the oxygen-generating air conditioner in the prior art when used outdoors. It effectively prevents the premature damage of the filter component 31 due to long-term dust accumulation, thereby greatly extending the service life of the filter component 31 and reducing maintenance and replacement costs.
