The two functions work together synchronously and complement each other, significantly improving filtration efficiency and self-cleaning ability. When the driving component is working, the impeller rotation not only generates suction to remove impurities cleaned by the cleaning component, but its rotation also drives the cleaning component to scrape the filter component through the transmission component, realizing a self-cleaning process with the dual functions of scraping the filter component and removing impurities. The actions of the airflow guiding component and the cleaning component are not independent of each other, but rather form a synergistic linkage under the coordination of the transmission component.

[0051] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other.

[0052] This application provides a self-cleaning filtration mechanism, such as... Figure 1-7 As shown, the self-cleaning filter mechanism mainly includes a support 100, a filter element 200, a cleaning element 300, a flow guiding assembly 400, and a transmission assembly 500. The self-cleaning filter mechanism provided in this embodiment can be applied to various pipeline systems or air conditioning systems that require airflow filtration, such as the air inlet of air conditioning equipment, and is particularly suitable for the return air inlet of a ducted air conditioner 600. This application uses the application of the self-cleaning filter mechanism at the return air inlet of a ducted air conditioner 600 as an example for illustrative purposes.

[0053] The filter element 200 of the self-cleaning filter mechanism is disposed on the support member 100; the cleaning member 300 is configured to reciprocate along a first direction to remove the filter material on the filter element 200; the flow guiding assembly 400 includes a drive member 410 and an impeller 420, the drive member 410 being used to drive the impeller 420 to rotate to generate airflow to remove the filter material removed by the cleaning member 300; the transmission assembly 500 is used to connect the flow guiding assembly 400 and the filter element 200, the transmission assembly 500 being configured to convert the rotational motion of the impeller 420 into the reciprocating linear motion of the cleaning member 300 along the first direction.

[0054] Support member 100 provides structural support and installation foundation for the entire filtration mechanism. Its shape can be customized according to the structure of the return air inlet of the duct unit 600 to ensure reliable fixation with the main unit system. Filter element 200 is installed on support member 100 and is used to filter the airflow entering the duct. It can be made of metal wire mesh, nylon mesh, or other durable, washable filter media, and can be designed with a corrugated or flat structure according to airflow requirements to increase the effective filtration area. Cleaning element 300 is attached to one side of filter element 200 and configured to reciprocate along a first direction on the surface of filter element 200 to clean accumulated impurities. Cleaning element 300 can include a scraper, brush, or blade, and its material can be a wear-resistant, anti-static composite material to improve cleaning efficiency and prevent secondary adhesion. The flow guiding assembly 400 includes a drive component 410 and an impeller 420. The drive component 410 drives the impeller 420 to rotate. When the impeller 420 rotates, it can create a local negative pressure near the cleaning area, thereby generating a guiding airflow to promptly remove dust and particles removed by the cleaning component 300, effectively preventing the redeposition of impurities after cleaning. The transmission assembly 500 connects the flow guiding assembly 400 and the cleaning component 300, converting the rotational motion of the impeller 420 into the reciprocating linear motion of the cleaning component 300, achieving synchronous transmission of the cleaning action. This structure avoids a complex independent drive system, making the entire device more compact and reliable in operation.

[0055] When the ducted air conditioner 600 is operating normally, the self-cleaning filter mechanism can work in conjunction with the fan, or it can be activated periodically or on demand through preset control logic. When the resistance of the filter element 200 increases or the operating time exceeds the limit, the system controller can activate the drive component 410, which drives the impeller 420 to form a negative pressure suction. At the same time, the transmission component 500 drives the cleaning component 300 to perform reciprocating scraping, thereby achieving automatic cleaning of the filter element 200. With the appropriate airflow channel design, the cleaned impurities can be guided into the dust collection area for subsequent periodic centralized cleaning.

[0056] The transmission assembly 500 achieves a multi-functional synergistic effect under the action of a single power source. Through the above structural arrangement, when the drive component 410 is working, the impeller 420 provides negative pressure airflow to suck up dust, and its rotation also drives the cleaning component 300 to reciprocate and clean through the transmission assembly 500, realizing the "simultaneous suction and brushing" of the filtration mechanism. The two functions work in sync and complement each other, significantly improving filtration efficiency and self-cleaning ability. Specifically, when the drive component 410 is working, the rotation of the impeller 420 not only generates suction to remove the impurities cleaned by the cleaning component 300, but its rotation also drives the cleaning component 300 to scrape the filter element 200 through the transmission assembly 500, thus realizing a self-cleaning process with the dual functions of scraping the filter element 200 and removing impurities. The actions of the flow guiding component 400 and the cleaning component 300 are not independent of each other, but rather form a synergistic linkage under the coordination of the transmission component 500. That is, one power source simultaneously drives two functional modules to complete mutually complementary cleaning actions, thereby significantly improving cleaning efficiency and dust removal effect. This makes the self-cleaning filter mechanism not only compact and highly automated, but also allows the flow guiding component 400 and the cleaning component 300 to work synergistically through the design of the transmission component 500. Thus, multiple functions are achieved with the simplest power source, which has extremely high practical value and promotion prospects in air handling systems such as the ducted air conditioner 600.

[0057] In some embodiments, the transmission assembly 500 includes a crank 510, a connecting rod 520, and a slider 530. The support 100 has a first groove 121 extending in a first direction. The slider 530 is slidably connected to the first groove 121. One end of the connecting rod 520 is rotatably connected to the crank, and the other end of the connecting rod 520 is rotatably connected to the slider 530. The flow guiding assembly 400 drives the crank 510 to rotate, and the slider 530 drives the cleaning component 300 to reciprocate.

[0058] The support member 100 is provided with a first groove 121 extending in a first direction, which guides the cleaning member 300 to perform linear reciprocating motion on the surface of the filter member 200. The sliding member 530 is slidably connected in the first groove 121, and its movement direction is consistent with the cleaning path of the cleaning member 300. The cleaning member 300 can be fixedly installed on the sliding member 530 and moves together with the sliding member 530. One end of the connecting rod 520 is rotatably connected to the crank member 510, and the other end is rotatably connected to the sliding member 530. When the driving member 410 in the flow guiding assembly 400 drives the impeller 420 to rotate, the crank member 510 rotates synchronously. Through the connecting rod 520, the sliding member 530 is driven to slide back and forth in a straight line in the groove. This linear motion drives the cleaning member 300 to sweep back and forth on the surface of the filter member 200, thereby continuously removing adhering dust, hair and other impurities. This structure allows the rotational motion of the flow guiding component 400 to be naturally coupled with the reciprocating linear motion of the cleaning component 300. It eliminates the need for auxiliary actuators such as electromagnetic push rods, cylinders, or motors, simplifying the overall design and improving service life and system stability.

[0059] In some embodiments, the transmission assembly 500 further includes a first gear 540 and a gear rod 550. A second gear 560 and a third gear 570 are coaxially arranged at both ends of the gear rod 550. The first gear 540 is coaxially arranged with the impeller 420. The second gear 560 is meshed with the first gear 540. The third gear 570 is meshed with the crank member 510.

[0060] The first gear 540 and gear shaft 550 of the transmission assembly 500 are used to further optimize the power transmission path, enabling the rotational power of the flow guiding assembly 400 to be efficiently transmitted to the cleaning component 300, and forming a compact transmission chain in structure. Specifically, the first gear 540 is coaxially arranged with the impeller 420 in the flow guiding assembly 400. When the driving component 410 drives the impeller 420 to rotate, the first gear 540 rotates synchronously. The second gear 560 at one end of the gear shaft 550 meshes with the first gear 540, thereby transmitting the rotation of the first gear 540 to the gear shaft 550. The third gear 570 at the other end of the gear shaft 550 meshes with the crank component 510, for driving the crank component 510 to rotate. It should be noted that the crank component 510 adopts a gear structure design in this embodiment, which facilitates meshing with the third gear 570 and can be rotatably connected to the connecting rod 520 through the eccentric part of its body, thereby realizing the crank motion function. One end of the connecting rod 520 is rotatably connected to the eccentric position of the crank component 510, and the other end is rotatably connected to the sliding component 530. When the crank component 510 rotates, the connecting rod 520 drives the sliding component 530 to slide back and forth along the first sliding groove 121 provided on the support component 100. The sliding component 530 is fixedly connected to the cleaning component 300, thereby driving the cleaning component 300 to reciprocate along the first direction, thereby realizing continuous cleaning of the surface of the filter component 200.

[0061] In this embodiment, the power source remains the drive component 410. Driven by it, the entire transmission system forms a complete power chain: gear meshing—eccentric crank—connecting rod 520—slider 530. Structurally, this achieves a precise conversion from rotary motion to linear reciprocating motion. The gears in the transmission assembly 500 are tightly meshed and compact, fully utilizing the energy generated during the impeller 420's rotation. While the guide assembly 400 generates airflow to adsorb impurities, the cleaning component 300 actively wipes the impeller through the same power source, effectively improving the cleaning effect.

[0062] In some embodiments, a flow guide cavity 122 is formed within the support member 100, and the impeller 420, the first gear 540, the second gear 560, and the gear rod 550 are disposed at one end of the second gear 560 within the flow guide cavity 122. On one hand, the flow guide cavity 122 is used to define the flow path of the airflow, serving as a path for the removal of dust and impurities; on the other hand, the gear rod 550 connects the first gear 540 inside the flow guide cavity 122 with the crank member 510 outside the flow guide cavity 122, thereby achieving power transmission without placing structures such as the crank member 510, connecting rod 520, and sliding member 530 within the flow guide cavity 122, thus protecting them from the influence of dust and impurities.

[0063] The guide cavity 122 formed inside the support member 100 in the self-cleaning filter mechanism is used to form a relatively closed airflow channel around the impeller 420 and other components, thereby limiting the airflow path and providing a protective space for the guide assembly 400 and part of the transmission structure. Specifically, the guide cavity 122 contains a portion of the structure of the impeller 420, the first gear 540, the second gear 560, and the gear rod 550. The second gear 560 is located at one end of the gear rod 550, which is located inside the guide cavity 122 and meshes with the first gear 540. The gear rod 550 transmits power to the third gear 570 and the crank member 510 outside the guide cavity 122. Firstly, the guide cavity 122 itself, as an independent and closed channel space, can effectively guide the airflow direction when used in conjunction with the impeller 420, ensuring that pollutants such as dust and impurities removed by the cleaning component 300 are discharged along a preset path, avoiding accumulation inside the structure and ensuring the cleaning efficiency of the filter element 200. Secondly, by using a gear rod 550 to pass through the wall of the guide cavity 122, the rotary drive structure inside the guide cavity 122 is connected to the crank assembly outside the guide cavity 122. This allows for efficient power transmission while placing dust-sensitive components such as the crank assembly 510, connecting rod 520, and sliding member 530 outside the guide cavity 122. This structural arrangement not only effectively prevents dust from causing wear and jamming at the hinge points of the sliding member 530 and connecting rod 520, but also facilitates subsequent maintenance and repair. In summary, this structure not only improves the integration and protection of the guide assembly 400, but also cleverly achieves a balance between cleaning efficiency, reliability, and maintenance convenience through the spatial separation design of the guide cavity 122 and part of the transmission assembly 500, fully demonstrating the technical advantages of the mechanical system in multi-functional integration and adaptability to the working environment.

[0064] In some embodiments, the support member 100 is provided with a collection groove 130 for collecting the filter material removed by the cleaning member 300, and the support member 100 is also provided with a dust collection box 140. The guide cavity 122 is connected to the collection groove 130 and the dust collection box 140 respectively. The impeller 420 is used to generate airflow to drive the filter material in the dust collection box to be transferred to the dust collection box 140 through the guide cavity 122.

[0065] The collection trough 130 is typically located below the filter element 200 to receive and temporarily store dust, impurities, and other contaminants scraped or brushed off by the cleaning element 300, preventing them from falling back into the airflow channel of the duct unit 600 or adhering to other structural surfaces. The dust collection box 140 on the support element 100 is used to centrally store the contaminants in the collection trough 130. The guide cavity 122 communicates with both the collection trough 130 and the dust collection box 140. The guide cavity 122 establishes an airflow transmission path through an air inlet on one side of the collection trough 130 and an air outlet on one side of the dust collection box 140. During system operation, the impeller 420 is driven to rotate by the drive element 410, generating a suction airflow. This airflow flows along the guide cavity 122 and draws in dust and impurities in the collection trough 130, thereby transporting the contaminants through the guide cavity 122 to the dust collection box 140 for centralized collection. This process does not rely on an additional power unit; it utilizes only the airflow generated by the impeller 420 of the flow guide assembly 400 itself to transfer the filtered material, thereby simplifying the structure and reducing energy consumption. Specifically, by connecting the flow guide cavity 122 to the collection tank 130 and dust collection box 140, the "collection-transfer-convergence" process of pollutants can be completed simultaneously during cleaning, improving the overall cleaning efficiency of the system. Furthermore, pollutants are directly guided from the collection tank 130 to the dust collection box 140 via the flow guide, preventing them from remaining near the filter element 200 or being re-entrained into the air passage, effectively improving air quality. By integrating the collection tank 130, dust collection box 140, and corresponding flow guide structures onto the support member 100, all filtered material processing paths are completed within the frame of the support member 100, avoiding complex external piping and resulting in a more compact structure. Optionally, the dust collection box 140 can be designed as a detachable structure for easy periodic cleaning.

[0066] In some embodiments, two cleaning elements 300 are provided, each respectively attached to the opposite surfaces of the filter element 200. That is, cleaning elements 300 are provided on both the air inlet and outlet sides of the filter element 200. This structural design allows dust or impurities to be effectively removed from the filter element 200 regardless of the direction from which they accumulate during operation. Specifically, each cleaning element 300 is configured to reciprocate along a first direction, thereby maintaining contact with its corresponding filter surface during movement to scrape or brush away contaminants adhering to the filter surface. The two cleaning elements 300 can be driven synchronously, or designed to move alternately or be controlled independently, depending on actual needs. This dual-sided cleaning structure offers the following technical advantages over single-sided cleaning: First, the sources of contamination differ between the inlet and outlet sides. For example, the inlet side is more prone to coarse dust particles, while the outlet side may accumulate fine suspended matter or condensate. By setting up dual-sided cleaning components 300, the entire filter surface can be effectively cleaned under any operating condition. Second, keeping both sides of the filter 200 clean avoids the accumulation of contaminants on one side over a long period, which can increase the pressure difference and extend the effective service life of the filter 200. The cleaned filter surface has lower resistance, which helps maintain stable airflow and air conditioning system energy efficiency. Third, even if one cleaning component 300 fails or wears out, the other side can continue to operate, providing redundancy and improving system reliability. Therefore, this implementation achieves a more efficient and comprehensive automated cleaning effect by setting independent cleaning components 300 on both sides of the filter 200 and combining synchronous or independently controlled movement. It is particularly suitable for scenarios such as ducted air conditioners 600 that have high requirements for air filtration accuracy and operational stability.

[0067] Based on the above embodiments, the sliding member 530 includes a connecting rod 531, a first slider 532, and a second slider 533. The connecting rod 531 is Y-shaped, and the first end of the connecting rod 531 is rotatably connected to the connecting rod 520. The first slider 532 and the second slider 533 are respectively disposed at the second end and the third end of the connecting rod 531. The first slider 532 and the second slider 533 are respectively used to drive the cleaning members 300 on opposite sides of the filter member 200.

[0068] The second and third ends of the connecting rod 531 are respectively connected to the first slider 532 and the second slider 533, thereby forming a double slider linkage structure that can transmit driving force in the first direction. The first slider 532 and the second slider 533 are respectively slidably connected in two parallel first slide grooves 121 provided on the support member 100. Each slider is fixedly connected to the cleaning member 300 on the corresponding side. Thus, under the drive of the transmission component 500, the two cleaning members 300 can achieve synchronous and consistent reciprocating sliding to remove the adhering substances on the air inlet and air outlet surfaces of the filter member 200. The Y-shaped connecting rod 531 rationally distributes the driving force at the end of one connecting rod 520 to the two cleaning components 300, avoiding the complex layout problems caused by setting two independent transmission paths. The two cleaning components 300 move synchronously under the drive of the sliding member 530, preventing the filter element 200 from shifting or deforming due to uneven force during cleaning, resulting in symmetrical movement and good stability. The coordinated movement of the two cleaning components 300 is achieved through a single power transmission path, simplifying the overall mechanical structure and facilitating assembly and maintenance. Simultaneous operation of the two cleaning components 300 significantly shortens the single cleaning cycle and improves the self-cleaning response speed. Therefore, this embodiment, by introducing the sliding member 530 with a Y-shaped connecting structure, achieves coordinated driving of the cleaning components 300 on both sides of the filter element 200, ensuring cleaning efficiency while also improving the overall reliability and maintainability of the structure. It is particularly suitable for air conditioning equipment with high requirements for filtration efficiency and operational continuity.

[0069] In some embodiments, two sets of the cleaning component 300, the flow guiding assembly 400, and the transmission assembly 500 are each provided, and arranged sequentially along the first direction. Both sets of the flow guiding assemblies 400 are located in the middle of the first direction, and both sets of the transmission assemblies 500 are located at both ends of the first direction. This arrangement of the two sets of flow guiding assemblies 400 in the middle of the first direction and the two sets of transmission assemblies 500 at both ends forms a structural configuration of "middle-center suction and two-end drive."

[0070] Each set of flow guiding components 400 is positioned opposite to its two corresponding cleaning components 300. The flow guiding component 400 includes a drive component 410 and an impeller 420, which provides suction while the cleaning components 300 remove impurities, drawing the impurities through the flow guiding cavity 122 and guiding them into the dust collection box 140. The two sets of flow guiding components 400 are located in the middle, which helps to create a symmetrical suction path, enabling the removal of cleaning materials nearby and improving dust collection efficiency.

[0071] The first direction is the length direction of the filter element 200. Both sets of flow guiding components 400 are located in the middle of this direction, generating suction to remove impurities removed by the cleaning component 300. Two sets of transmission components 500 are located at opposite ends of the first direction. Each transmission component 500 can control the synchronous cleaning action of the two cleaning components 300 on the air inlet and outlet sides of the filter element 200. Specifically, the connecting rod 531 of the sliding member 530 of each transmission component 500 can be Y-shaped, with one end connected to the connecting rod 520, and the other two ends connected to the cleaning components 300 on the air inlet and outlet sides of the filter element 200 respectively via the first slider 532 and the second slider 533. Because the two sets of transmission components 500 are located at both ends of the filter element 200's length direction, forming a symmetrical distribution structure with the flow guiding components 400 located in the middle, the displacement path of the cleaning components 300 driven by each transmission component 500 is effectively shortened, reducing structural load and energy consumption, and improving motion response speed and efficiency.

[0072] Furthermore, the structural design of central dust collection and two-end drive not only improves cleaning efficiency but also optimizes the distribution of cleaning paths and dust flow guidance paths within the filtration area. Only one flow guide cavity 122 can be designed in the middle below the central support member 100. The impellers 420 of the two sets of flow guide components 400 and the first gears 540 of the two sets of transmission components 500 are all located in the same flow guide cavity 122. Transmission cavities 123 are arranged on both sides of the flow guide cavity 122. The fixed third gear 570, crank 510, connecting rod 520 and sliding member 530 in the two sets of transmission components 500 are all located in the transmission cavities 123 on both sides. The transmission structure in the flow guide cavity 122 and the transmission structure in the transmission cavities 123 on both sides are connected by the gear rods 550 of the two sets of transmission components 500. The central guide cavity 122 is designed to concentrate the dust guide path and enhance dust collection efficiency. The transmission cavities 123 distributed on both sides avoid the centralized arrangement of complex mechanisms, improving structural stability and maintenance convenience. By modularly arranging the first gear 540, gear rod 550, third gear 570 and crank component 510 in different functional cavities, the risk of dust intrusion into the transmission structure is reduced and reliability is enhanced.

[0073] In some embodiments, the support member 100 includes a fixing part 110 and a bottom chamber 120 arranged vertically, the filter member 200 is a filter screen disposed on the fixing part 110, the bottom chamber 120 is provided with a receiving cavity, and the transmission assembly 500 and the flow guiding assembly 400 are disposed in the receiving cavity.

[0074] The filter element 200 is a filter screen installed on the fixed part 110, used to intercept dust and impurities in the airflow; the bottom chamber 120 is located below the filter element 200, and its interior forms a receiving cavity for installing various functional components. Specifically, the receiving cavity includes the flow guiding cavity 122 and the transmission cavity 123 mentioned in the previous embodiment, which are used for arranging the dust collection and power transmission functional modules, respectively. The flow guiding assembly 400 and the transmission assembly 500 are both disposed in this receiving cavity. Among them, the flow guiding cavity 122 is located in the middle of the bottom chamber 120, used to accommodate the impeller 420 and the first gear 540 arranged coaxially with it. The flow guiding cavity 122, on the one hand, defines the airflow distribution path, so that the impurities removed by the cleaning component 300 can be concentrated and discharged under the action of airflow, and on the other hand, provides a sealed space to isolate dust from the transmission structure. The transmission chamber 123 is located on both sides of the guide chamber 122, and is used to install the second gear 560, the third gear 570, the crank 510, the connecting rod 520, and the sliding member 530 in the transmission assembly 500, respectively. This embodiment has a clearly defined structural partition, with the fixed part 110 and the bottom chamber 120 distributed vertically, which helps to organically separate the filtration function and the driving cleaning function, facilitating modular design and assembly. The guide assembly 400 and the transmission assembly 500 are integrated into the receiving cavity of the bottom chamber 120, resulting in a compact overall structure and reduced installation volume. The transmission components and dust collection components are separated into different chambers to avoid dust causing wear and jamming of the transmission mechanism, and also facilitates later maintenance, cleaning, or replacement operations.

[0075] In some embodiments, the fixing part 110 has an opening 111 at the end away from the bottom compartment 120 for inserting or removing the filter screen. This opening 111 facilitates the installation and maintenance of the filter element 200, allowing users to quickly install, remove, and replace the filter screen without disassembling the entire support structure.

[0076] Specifically, the opening 111 can be located at the top of the fixing part 110, and the filter screen can be slidably or pull-outly installed inside the fixing part 110. By providing the opening 111 on the fixing part 110, the filter screen can be replaced or cleaned without disassembling the entire machine or other key components, improving the maintainability of the entire machine and the user experience. This is especially suitable for air filtration scenarios that require regular cleaning of dust and impurities, such as duct air conditioners 600, central air conditioning return air vents, and purification devices. To fix the filter element 200, one or more first fixing holes 112 are provided on the fixing part 110, preferably corresponding to the corners of the filter element 200, to assist in fixing the filter element 200. For example, the first fixing hole 112 can be a threaded hole, which can be fixedly connected by countersunk screws engaging with the threaded hole.

[0077] In some embodiments, the cleaning component 300 includes a cleaning part 310 and a driving part 320 connected to each other. The bottom compartment 120 has a top wall 124 connected to the fixing part 110. The top wall 124 has a second groove 125 extending along the first direction on the side facing the fixing part 110. The driving part 320 is slidably engaged with the second groove 125. A first groove 121 is formed on the side of the top wall 124 located in the receiving cavity. The first groove 121 communicates with the second groove 125 to realize the connection between the sliding component 530 and the driving part 320.

[0078] The drive unit 320 receives driving force from the transmission assembly 500. The drive unit 320 is disposed in and slides within the second slide groove 125 to achieve reciprocating linear movement in the first direction, thereby driving the cleaning unit 310 to reciprocate and wipe the filter element 200. The first slide groove 121 and the second slide groove 125 are connected, allowing the sliding member 530 disposed in the receiving cavity to pass through the first slide groove 121 and connect with the drive unit 320. This transmits the motion of the connecting rod 520 driven by the crank member 510 to the drive unit 320, achieving synchronous reciprocating cleaning action of the cleaning member 300. With this structure, the cleaning member 300 can slide reciprocally along the length of the filter element 200 (i.e., the first direction), effectively removing dust and impurities attached to the filter screen in conjunction with the airflow suction provided by the flow guiding assembly 400, improving the system's automated cleaning capability and ease of use.

[0079] In some embodiments, the support member 100 further includes a pull-out portion 150 connected to both the fixing portion 110 and the base chamber 120. The pull-out portion 150 is located at one end of the support member 100 in a first direction. The edge of the pull-out portion 150 protrudes from the fixing portion 110 and the base chamber 120, forming an outer edge structure that facilitates positioning and installation during the overall insertion process. Specifically, the pull-out portion 150 is used to form a fixed connection with the structure of the duct unit 600 after the entire self-cleaning filter mechanism, including the fixing portion 110 and the base chamber 120, is inserted into the installation space inside the duct unit 600. This connection is achieved, for example, through snap-fit, screw, or slide rail engagement, ensuring the stability of the entire self-cleaning filter mechanism during use and preventing displacement or loosening. For example, one or more second fixing holes 151 are provided on the pull-out portion 150 to assist in fixing the self-cleaning filter mechanism. The second fixing holes 151 can be threaded holes, which can be fixedly connected by countersunk screws engaging with the threaded holes.

[0080] This structure facilitates modular installation, disassembly, and maintenance of the self-cleaning filter mechanism, improving product assembly efficiency and allowing users or maintenance personnel to quickly replace or clean components when needed. The pull-out section 150, as an externally accessible part, can also be customized to fit the interface structures of different duct air conditioner models 600, enhancing product versatility and adaptability.

[0081] This invention also protects an air conditioning device, which includes the self-cleaning filter mechanism provided in the foregoing embodiments of this application. This self-cleaning filter mechanism is used to filter the airflow in the airflow channel within the air conditioning device. The air conditioning device includes, but is not limited to, the following: Figure 1 The self-cleaning filter mechanism of the duct air conditioner 600 shown is provided, but is not limited to, at the return air inlet of the duct air conditioner 600.
