Description

Technical Field

[0001] The present application relates to the field of air conditioning, and in particular, to a filtering device, an air conditioning outdoor unit, an air conditioner, and an air conditioning control method. Background Art

[0002] As people continue to pursue a healthier living environment, the application of air purification technology in HVAC equipment has become increasingly important. This is especially true for air conditioning systems with integrated oxygen generation. Filters must not only remove impurities, microorganisms, and harmful substances from the air, but also ensure that the oxygen generation process is not disrupted and that the produced oxygen is sufficiently pure.

[0003] However, existing oxygen-generating air conditioning filters have exposed a series of problems in actual use, which limit their performance and ease of maintenance. Specifically, they include:

[0004] 1. Decreased filtration efficiency: After long-term operation, the filter of the oxygen-generating air conditioner will gradually lose its original filtration efficiency due to the accumulation of dust and impurities, resulting in increased filtration resistance and obstructed air circulation, which not only affects the cooling and heating effects of the air conditioner, but also directly reduces the working efficiency of the oxygen production module.

[0005] 2. Inconvenient cleaning and maintenance: Traditional filter cleaning methods, such as manual disassembly and washing, are time-consuming and labor-intensive, with limited effectiveness and difficulty in thoroughly removing deep-seated dirt. These cleaning methods can also damage the filter structure, accelerating aging and shortening its service life. For filters installed in outdoor units, cleaning becomes even more difficult and complex, causing inconvenience to users.

[0006] 3. High maintenance costs: Frequent manual maintenance and filter replacement not only increases time costs but also imposes a financial burden. Improper or excessive maintenance will significantly increase the overall operating costs of the air conditioning system and affect the economic benefits of the equipment.

[0007] 4. Inadequate ability to meet the unique demands of oxygen production: The oxygen production process may produce special byproducts or ultrafine particles, which place even more stringent requirements on the filter than those for filtering impurities in ordinary air. However, existing filtration technologies often ignore these special demands, resulting in poor filter performance during the oxygen production process and easy clogging, which further reduces filtration efficiency and even affects the efficiency and life of the entire equipment.

[0008] In summary, the existing oxygen-generating air conditioning air filter technology faces a series of challenges, such as the filtration efficiency decays over time, the cleaning and maintenance are complex and costly, and it is difficult to meet the special needs of oxygen production.

[0060] 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.

[0061] It should be noted that, unless otherwise specified, all technical and scientific terms used in this application have the same meaning as commonly understood by ordinary technicians in the technical field to which this application belongs.

[0062] In the present invention, unless otherwise specified, the directional words used, such as "up, down, top, bottom", usually refer to the directions shown in the drawings, or to the components themselves in the vertical, perpendicular or gravity direction; similarly, for ease of understanding and description, "inside and outside" refer to the inside and outside relative to the outline of each component itself, but the above directional words are not used to limit the present invention.

[0063] Please refer to Figures 1 to 11According to the first aspect of the present application, a filter device 1 is provided, comprising: a filter assembly 10, the filter assembly 10 comprising: a filter part 11 and a cleaning part 12, the filter part 11 and the cleaning part 12 being relatively movably arranged to clean the dust on the filter part 11 when the filter part 11 and the cleaning part 12 move relative to each other; a bottom plate assembly 20, the bottom plate assembly 20 being located below the filter assembly 10, the bottom plate assembly 20 comprising a shielding bottom plate 21, the shielding bottom plate 21 being movably shielded at the communication port to open or close the communication port; the communication port is opposite to the filter part 11, so that the dust cleaned by the cleaning part 12 falls below the communication port.

[0064] This application utilizes the relative motion between the filter and cleaning components to effectively remove dust from the filter. Simultaneously, by adjusting the position of the shielding base plate 21 of the base plate assembly 20, the connecting port is opened, ensuring that dust can be discharged promptly and preventing secondary contamination. This significantly improves air filtration efficiency, reduces maintenance costs, and extends the life of the equipment. The filter device can be used in air conditioning systems, particularly those requiring high-efficiency filtration and self-cleaning oxygen-generating air conditioners.

[0065] In the filtering device of the present application, the cleaning component 12 includes a brush 121. The structure of the filtering component 11 can be in various forms, specifically:

[0066] In one embodiment, the filter component 11 includes a drum filter 111, and the filter component 11 is rotatably arranged. The brush is arranged on one side of the drum filter 111 and contacts the drum filter 111 to clean the dust on the drum filter 111 during the rotation of the filter component 11.

[0067] In another embodiment, the filter component 11 includes a straight-plate filter screen, the brush 121 is located on one side of the straight-plate filter screen and contacts the straight-plate filter screen, and the brush is movably arranged in a direction parallel to the straight-plate filter screen to clean the dust on the straight-plate filter screen during the movement of the brush.

[0068] The principle of the above two embodiments is to remove dust attached to the filter screen by friction through the contact between the brush and the filter screen. The design of the drum filter screen allows the brush to follow the rotation of the filter screen for cleaning, while the straight-plate filter screen is cleaned by the movement of the brush along the plane of the filter screen. This arrangement improves the thoroughness and efficiency of cleaning and reduces the need for manual intervention. It can be used in household and commercial air-conditioning systems, especially those environments that require continuous and efficient filtration. After the filter screen reaches a certain amount of dust accumulation, the self-cleaning mode (i.e., the mode in which the cleaning component 12 automatically cleans the filter component 11) is automatically or manually started to ensure the cleanliness of the filter screen.

[0069] In order to realize the driving of the filter component 11 or the cleaning component 12, as Figure 1 and Figure 2 As shown, the filtering device further includes a driving assembly 30 , which is drivingly connected to the filtering component 11 or the cleaning component 12 and is used to drive the filtering component 11 and the cleaning component 12 to move relative to each other.

[0070] The drive assembly works by transmitting power to the filter element through an external power source, such as an electric motor, enabling rotational or linear motion, thereby achieving a self-cleaning function. Drive assembly 30 automates the cleaning process, improving cleaning efficiency and reducing energy consumption. This approach can be applied to all filtering devices requiring self-cleaning functions, such as air conditioners and air purifiers. When cleaning is required, the drive assembly automatically activates, driving the filter element and cleaning element into relative motion to complete the cleaning task.

[0071] In this application, the following methods are used to achieve the movement of the shielding base plate 21:

[0072] In one implementation, the driving assembly 30 is respectively connected to the filter component 11 and the shielding bottom plate 21, so that when the driving assembly 30 drives the filter component 11 to move, the shielding bottom plate 21 is synchronously driven to move to open the communication port;

[0073] In another implementation, the filter component 11 is connected to the shielding bottom plate 21 by transmission, so that when the filter component 11 moves, the shielding bottom plate 21 is driven to move to open the connecting port. The principle of this embodiment is to use the movement of the filter component to control the opening and closing action of the shielding bottom plate through a transmission or drive connection to ensure that dust can be discharged smoothly during cleaning. This arrangement improves the coordination and efficiency of the cleaning process and avoids dust retention and secondary pollution. During the cleaning process of the filter component, the shielding bottom plate automatically opens and automatically closes after cleaning is completed to ensure the effective discharge of dust.

[0074] The specific structure of the driving assembly 30 in this application is as follows: Figure 1 As shown, the driving assembly 30 includes a driving motor 31 and a driving gear 32. The driving gear 32 is installed on the output shaft of the driving motor 31. A driven gear 113 is provided on the filter component 11. The driving gear 32 is engaged with the driven gear 113 to drive the filter component 11 to rotate around its axis.

[0075] The drive motor and gear combination works by transmitting the motor's rotational force through the driving gear to the driven gear, driving the filter element to rotate and achieve self-cleaning of the filter. This provides a stable and reliable driving force, ensuring the continuity and effectiveness of the cleaning process. When cleaning mode is activated, the drive motor rotates the filter element, and the brush cleans the filter surface, discharging dust through the connecting port.

[0076] In this application, if Figures 1 to 8 As shown, the filter component 11 includes a drum-type filter screen 111 and a cam 114, the cam 114 is arranged at one end of the drum-type filter screen 111, and the shielding bottom plate 21 is provided with a protrusion 211 that cooperates with the cam 114; the filter component 11 is rotatably arranged so that during the rotation of the filter component 11, when the cam 114 abuts against the protrusion 211, the shielding bottom plate 21 is pushed to open the communication port through the interaction force, and after the cam 114 is disengaged from the protrusion 211, the shielding bottom plate 21 is released.

[0077] This embodiment utilizes the contact and disengagement of a cam with a raised portion on the shielding base to control the base's opening and closing, enabling immediate dust removal. This improves the immediacy and efficiency of cleaning and prevents dust accumulation and secondary contamination. As the filter rotates for cleaning, the cam contacts the raised portion, pushing the shielding base open. Once cleaning is complete, the cam disengages from the raised portion, automatically closing the shielding base.

[0078] Specifically, the cams 114 are provided at both opposite ends of the drum filter 111, and the protrusions 211 that cooperate with the cams 114 are provided at both ends of the shielding bottom plate 21; and / or, the filter component 11 also includes an air pipe 115, and the air pipe 115 is connected to the inner cavity of the drum filter 111.

[0079] Cams at both ends of the drum filter ensure smooth movement of the shielding base 21. The connection between the air duct and the filter cavity allows for smooth airflow and effective dust removal, thereby improving cleaning uniformity and airflow flow, further enhancing filtration efficiency. In cleaning mode, the cams at both ends of the drum filter operate synchronously to ensure comprehensive cleaning of the filter surface, while the air duct maintains unobstructed airflow and prevents airflow blockage.

[0080] In this application, if Figure 3 and Figure 11 As shown, the base plate assembly 20 also includes a base component 22, and a guide groove 221 is provided on the base component 22. The guide groove 221 slides with the protrusion 211, so that when the cam 114 pushes the protrusion 211 to move, the protrusion 211 slides in the guide groove 221, so that the shielding bottom plate 21 gradually overlaps with at least part of the base component 22.

[0081] The guide grooves and raised sections slide together to control the movement of the shielding plate, ensuring accurate dust removal during cleaning. This improves the accuracy and reliability of the cleaning process and avoids deviations in dust removal. In cleaning mode, the cam pushes the raised sections along the guide grooves, causing the shielding plate to follow a predetermined trajectory, ensuring accurate dust removal.

[0082] The specific structure of the base plate assembly 20 can be in various forms:

[0083] In one embodiment, the base component 22 is a plate, so that when the cam 114 pushes the raised portion 211 to move, the shielding bottom plate 21 gradually overlaps one side of the base component 22. This solution utilizes the plate structure of the base component to ensure that the shielding bottom plate can be smoothly overlapped on one side when opened, preventing instability during movement, thereby improving the stability and reliability of the bottom plate assembly and reducing the failure rate during cleaning. In cleaning mode, the shielding bottom plate is smoothly overlapped on one side of the base component, ensuring that the communication port is fully open and facilitating dust discharge.

[0084] In another embodiment, the base component 22 has a accommodating cavity 222, and the guide groove 221 is arranged on the cavity wall of the accommodating cavity 222, so that when the cam 114 pushes the protrusion 211 to move, the shielding bottom plate 21 gradually extends into the accommodating cavity 222, and the interior of the accommodating cavity 222 pushes the dust on the shielding bottom plate 21.

[0085] The principle behind this implementation is that the design of the housing cavity ensures that the shielding bottom plate 21 can extend into the cavity when opened. The inner wall of the housing cavity cooperates with the upper surface of the shielding bottom plate 21, utilizing the space within the cavity to promote dust discharge while preventing dust from remaining on the bottom plate assembly. This improves the efficiency and thoroughness of dust discharge and reduces the problem of residual dust after cleaning. In cleaning mode, the shielding bottom plate extends into the housing cavity, utilizing the space within the cavity to promote dust discharge. After cleaning is complete, the shielding bottom plate returns to its original position, ensuring a clean area beneath the filter.

[0086] In order to reset the shielding bottom plate 21, the bottom plate assembly 20 further includes a reset elastic member 24, the two ends of which are respectively connected to the base component 22 and the shielding bottom plate 21, so that when the cam 114 disengages the protrusion 211, the shielding bottom plate 21 is reset to its initial position below the filter component 11 under the action of the reset elastic member 24; and / or, a cleaning member is provided on the base component 22, so that during the movement of the shielding bottom plate 21, the cleaning member can clean dust on the shielding bottom plate 21. The present application utilizes the elastic force of the reset elastic member to ensure that the shielding bottom plate can be quickly reset after cleaning is completed. At the same time, the provision of the cleaning member further cleans the residual dust on the shielding bottom plate, thereby improving the degree of automation and cleaning effect of the cleaning process and reducing the need for manual intervention.

[0087] In the cleaning mode, the shielding bottom plate is automatically reset under the action of the reset elastic member, and the cleaning component removes the residual dust on the shielding bottom plate to ensure thorough cleaning.

[0088] In order to achieve automatic control, the filtering device also includes a dust detector, which is arranged on the filtering component 11 to detect the degree of dust accumulation on the filtering component 11; and / or, the filtering device also includes a position detector, which is arranged on the base plate assembly 20 to detect the position of the shielding base plate 21.

[0089] This application realizes real-time monitoring of the status of the filter device through the provision of a dust detector and a position detector, ensuring the timely activation of the self-cleaning mode and the accurate control of the position of the shielding bottom plate, thereby improving the intelligence level and cleaning efficiency of the filter device and reducing maintenance costs. When the filter device is running, the dust detector monitors the dust accumulation level of the filter component in real time, and the position detector monitors the position of the shielding bottom plate, ensuring the timely activation of the self-cleaning mode and the accurate control of the position of the shielding bottom plate, thereby achieving efficient operation of the filter device.

[0090] According to a second aspect of the present application, an air conditioner outdoor unit is provided, such as Figure 9 and Figure 10As shown, the air conditioner outdoor unit includes: an outdoor housing 40, the air conditioner outdoor unit also includes: a support frame 50, the support frame 50 is arranged on the top of the outdoor housing 40; an oxygen production component 60, an air compressor component 70 and a filter device, the oxygen production component 60, the air compressor component 70 and the filter device are all arranged in the support frame 50; wherein the filter device is the filter device mentioned above. Figures 4 to 8 Partial cross-sectional view of the air conditioner outdoor unit.

[0091] Integrating the filter into the support frame of the air conditioner's outdoor unit utilizes the unit's natural ventilation to improve both the filter's cleaning efficiency and the oxygen generator's operating efficiency. This optimizes the air conditioning system's design, improves overall performance, and reduces maintenance costs. During operation, the filter automatically activates self-cleaning mode, ensuring cleanliness of the filter components while simultaneously maintaining the proper functioning of the oxygen generator and air compressor, resulting in highly efficient oxygen production.

[0092] It can be seen that placing the filter in the external unit significantly reduces the size of the internal unit, improves installation flexibility and aesthetics, and saves indoor space. The structural design of the drum filter allows the filter to self-clean, eliminating the need for manual filter replacement or cleaning. The structural design of the filter base allows dust removed from the filter to be cleaned promptly, improving the filter's self-cleaning effect.

[0093] According to a third aspect of the present application, an air conditioner is provided, comprising an outdoor air conditioner unit and an indoor air conditioner unit connected by a pipeline, wherein the outdoor air conditioner unit is the aforementioned outdoor air conditioner unit. This solution connects the outdoor air conditioner unit and the indoor air conditioner unit via a pipeline to achieve air circulation and filtration, while utilizing the outdoor unit's filter device for self-cleaning, thereby improving the overall performance and user experience of the air conditioning system, thereby optimizing the layout of the air conditioning system, improving air purification efficiency, and reducing maintenance costs.

[0094] When the air conditioner is running, the filter device of the air conditioner outdoor unit automatically starts the self-cleaning mode to ensure the cleanliness of the filter components. At the same time, the air conditioner indoor unit provides comfortable indoor temperature and humidity, achieving efficient air purification and a comfortable experience.

[0095] According to a third aspect of the present application, an air conditioning control method is provided, which is applicable to the air conditioner, such as Figure 12 As shown, the air conditioner has a self-cleaning mode for cleaning the filter component 11 of the filter device 1 of the air conditioner outdoor unit, and the air conditioning control method includes: obtaining an instruction to start the self-cleaning mode; after receiving the instruction to start the self-cleaning mode, driving the shielding bottom plate 21 of the filter device 1 to move to a position where the connecting port is opened, and driving the filter component 11 and the cleaning component 12 of the filter device 1 to move relative to each other to start the self-cleaning mode.

[0096] This control method automatically controls the opening of the filter's shielding plate by receiving a self-cleaning mode command, while simultaneously driving the filter and cleaning components in relative motion to achieve self-cleaning of the filter. This improves the automation and cleaning efficiency of the air conditioning system and reduces the need for manual intervention. Users send a self-cleaning mode command via a remote control or smart device, and the air conditioning control system automatically responds, controlling the filter's self-cleaning process to ensure filter cleanliness and improve the system's operating efficiency.

[0097] In the present application, the air conditioning control method further includes: after the air conditioner has been running in the self-cleaning mode for a predetermined period of time, detecting the dust level on the filter component 11; when the dust level on the filter component 11 exceeds a predetermined value, restarting the self-cleaning mode until the dust level on the filter component 11 is lower than the predetermined value; otherwise, ending the self-cleaning operation of the cleaning component 12 on the filter component 11 (i.e., ending the cleaning process of the self-cleaning mode). This control method detects the dust level on the filter component through a dust detector after the self-cleaning mode has been running for a period of time, and decides whether to continue cleaning or end cleaning based on the detection results, thereby improving the intelligence and cleaning effect of the self-cleaning mode and avoiding the problems of over-cleaning or under-cleaning. During the operation of the self-cleaning mode, the air conditioning control system regularly detects the dust level of the filter component and automatically adjusts the running time of the cleaning mode based on the detection results to ensure the cleanliness of the filter and improve the operating efficiency and user experience of the air conditioning system.

[0098] After the self-cleaning mode ends, the air-conditioning control method further includes: detecting whether the shielding bottom plate 21 is in the closed position closing the connecting port; when the shielding bottom plate 21 is in the closed position, ending the self-cleaning mode; otherwise, driving the shielding bottom plate 21 to move to the closed position. The principle of this control method is to confirm whether the shielding bottom plate completely closes the connecting port after the self-cleaning mode ends through a position detector. If it is not closed, the shielding bottom plate is automatically driven to the closed position to ensure the sealing and cleaning effect of the filter device, thereby improving the integrity and reliability of the self-cleaning mode and preventing dust from re-entering the filter after cleaning and affecting the filtration efficiency. After the self-cleaning mode ends, the air-conditioning control system automatically detects the position of the shielding bottom plate. If it is not completely closed, the shielding bottom plate is automatically driven to the closed position to ensure the sealing of the filter device and prevent dust from re-entering the filter after cleaning and affecting the filtration efficiency and equipment performance.

[0099] In summary, the technical solution proposed in this application not only solves the problems faced by existing oxygen-generating air conditioning air filters in long-term use, such as decreased filtration efficiency, difficulty in cleaning, high maintenance costs, and inability to effectively respond to special needs during the oxygen production process, but also achieves self-cleaning of the filter and immediate dust discharge through innovative design and mechanism of the drum filter, significantly improving the performance of the air conditioning system and user experience. This technical solution has a wide range of applications, from homes to businesses, to industry and medical fields, and can leverage its unique advantages to provide users with more efficient, convenient, and intelligent air purification solutions.

[0100] An air conditioner consists of an indoor unit and an outdoor unit. These units are connected by pipes and wiring. The air conditioner's oxygen generator and oxygen filter are located in the outdoor unit or in the outdoor area.

[0101] The outdoor unit is primarily composed of a heat exchange compressor, heat exchanger components, piping components, a fan assembly 80, a housing, electrical components, a support frame 50, an oxygen generator, and a filter. These components, such as the heat exchange compressor, heat exchanger components, piping components, fan blades, housing components, and electrical components, are typical components of an air conditioner outdoor unit and are not described in detail here.

[0102] The support frame 50 is made of a high-strength material or designed to be a high-strength structure. It is positioned above the fan blades and heat exchanger of the fan assembly 80 and is assembled or secured to the side housing of the outdoor unit. It houses, secures, and supports the oxygen generator and filter. A hole is provided on the bottom plate of the support frame 50, connecting the heat exchange chamber below with the space above where the oxygen generator is located, allowing for air circulation and heat dissipation.

[0103] The oxygen generator and the oxygen filter are mounted on a support frame 50. The oxygen filter is divided into an air intake filter assembly (i.e., a filter assembly) and a switch base assembly (i.e., a base assembly). The air intake filter assembly comprises a drum-type HEPA filter, a motor, a cam, and a brush. Cams are fixed at both ends. During cleaning, the cam and the filter rotate synchronously with the motor (the brush remains stationary), and the brush removes dust from the filter. During oxygen production, air is sucked into the drum-type filter through the air compressor (air compressor assembly 70) and is then transferred to the oxygen production module through the air pipe 115.

[0104] The switch base assembly consists of a switch base (shielding base 21), a spring (reset elastic member 24), and a base component 22. When working, the drive motor on the air intake filter assembly drives the drum filter and the cam to rotate. When the outermost point of the cam contacts the convex point on the shielding base 21, the shielding base 21 is pushed open. Figure 5 and Figure 6As shown, the dust falling on the shielding bottom plate 21 falls with the vibration of the shielding bottom plate 21 during its movement, and the dust swept by the brush falls to the fan assembly 80 and is blown out of the external machine; after the cam rotates for a certain distance, the cam and the convex point reach the critical point of contact, as shown in FIG. Figure 7 and Figure 8 As shown. The shielding bottom plate 21 reaches the critical point of closing; when the cam rotates past the critical point, the cam and the convex point are no longer in contact, as shown. Figure 4 As shown, at this time, the shielding bottom plate 21 is ejected by the elastic force of the spring, so that the shielding bottom plate 21 is completely closed.

[0105] The working process of air conditioner:

[0106] like Figure 13 As shown, the air conditioning oxygen production function is started, the air compressor of the oxygen production device is started, and the air in the heat exchange chamber passes through the holes on the bottom plate of the support frame, the filter device 1, the air compressor assembly 70, the solenoid valve 2, and the molecular sieve 3 in sequence. After the air is filtered in the molecular sieve 3, the enriched oxygen enters the gas storage tank 5 through a one-way valve 4 and can be input into the room through the gas pipeline; the nitrogen passes through another one-way valve 4, the molecular sieve 3 and the muffler 6 and is discharged.

[0107] like Figure 12 As shown, there are four ways to start the self-cleaning mode of the air intake filter assembly, namely, automatic start after the oxygen production mode ends; automatic start of the self-cleaning mode after the oxygen production mode has run for a certain period of time; the sensor detects excessive dust accumulation on the filter screen and manual control to start the self-cleaning mode.

[0108] After the self-cleaning mode is started, the motor of the air intake filter assembly starts, the drum filter starts to roll, and the brush starts to clean the accumulated dust on the filter, causing the dust to fall onto the shielding bottom plate 21. When the cam on the air intake filter assembly contacts the convex point on the switch bottom plate, it pushes the shielding bottom plate 21 to open, allowing the accumulated dust cleaned by the brush to fall off, and as the fan blades in the heat exchange chamber rotate, the dust is sucked into the heat exchange chamber through the holes on the bottom plate of the support frame and blown out to the outside.

[0109] After the self-cleaning mode is activated, it will operate for a certain period of time in the above manner. After the operation stops, it will automatically detect the dust accumulation level of the filter. If the dust accumulation level exceeds the set value, the self-cleaning mode will be activated again and operate until the sensor detects the dust accumulation level of the filter again and the dust accumulation level reaches or falls below the set value.

[0110] After the self-cleaning mode stops and the dust accumulation detection of the filter is completed, the sensor on the shielding bottom plate 21 detects whether the switch bottom plate is completely closed. If the sensor contacts the shielding bottom plate 21, the shielding bottom plate 21 is completely closed. If the sensor does not detect contact with the shielding bottom plate 21, the shielding bottom plate 21 is still open. At this time, the drive motor on the air intake filter assembly is activated, so that the cam and the protrusion are no longer in contact. The shielding bottom plate 21 is then fully closed by the elastic force of the spring.

[0111] When the filter needs to be replaced manually, remove part of the outer cover of the external unit to expose the internal air intake filter assembly. The HEAP net can be replaced by removing and replacing the drum HEPA net on the air intake filter assembly.

[0112] In the air conditioning control method, upon receiving a command to activate the self-cleaning mode, the drive assembly 30 is activated, the shielding base 21 moves to a position that opens the communication port, and the cleaning component 12 immediately begins to sweep dust from the filter element 11. After the self-cleaning mode runs for a certain period of time, a dust detector checks the dust accumulation level of the filter element. If the dust concentration exceeds a preset value, the system automatically restarts the self-cleaning process until the dust accumulation drops below a safe level. This method avoids the inconvenience of manual intervention, realizes automated management and maintenance, and improves user satisfaction.

[0113] In summary, the filtering device proposed in this application and its application in the air-conditioning system, by introducing intelligent switch design, dynamic dust removal mechanism and automatic monitoring system, greatly improves the air purification quality and the self-cleaning efficiency of the equipment, reduces maintenance costs and frequency, and also optimizes the spatial layout of the indoor and outdoor units of the air conditioner, reflecting a major breakthrough in the field of oxygen-generating air-conditioning technology, and has made a significant contribution to improving public and household air quality.
