For example, "connected" can be a fixed connection, a detachable connection, or an integral structure; it can be a mechanical connection or an electrical connection; it can be directly connected, or indirectly connected through an intermediate medium, or there can be internal communication between two devices, elements or components.

[0051] It should be noted that, without conflict, the embodiments and features in the embodiments of the present application can be combined with each other.

[0052] The embodiment of the present application provides a self-cleaning filtering mechanism, as Figures 1-7 shown. The self-cleaning filtering mechanism mainly includes a support member 100, a filtering member 200, a cleaning member 300, a diversion assembly 400 and a transmission assembly 500. The self-cleaning filtering mechanism provided in this embodiment can be applied to various pipeline systems or air conditioning systems that need to filter air flow, such as the air inlet of air conditioning equipment, and is particularly applicable to the return air outlet of an air duct machine 600. The present application takes the self-cleaning filtering mechanism applied to the return air outlet of the air duct machine 600 as an example for exemplary illustration.

[0053] The filter element 200 of the self-cleaning filter mechanism is arranged on the support member 100; the cleaning member 300 is configured to be able to move back and forth along a first direction to remove the filter material on the filter element 200; the guide component 400 includes a driving member 410 and an impeller 420, and the driving member 410 is used to drive the impeller 420 to rotate to generate an airflow to absorb the filter material removed by the cleaning member 300; the transmission component 500 is used to connect the guide component 400 and the filter element 200, and the transmission component 500 is configured to convert the rotational motion of the impeller 420 into a reciprocating linear motion of the cleaning member 300 along the first direction.

[0054] The support member 100 is used to provide structural support and installation foundation for the entire filtering mechanism. Its shape can be customized according to the structure of the return air outlet of the duct machine 600 to ensure reliable fixation with the host system. The filter element 200 is installed on the support member 100 and is used to filter the airflow entering the air duct. The material can be a metal mesh, nylon mesh or other washable filter materials with good durability, and can be designed as a corrugated or flat structure according to the air volume requirements to expand the effective filtering area. The cleaning member 300 is attached to one side of the filter element 200 and is configured to reciprocate along the first direction on the surface of the filter element 200 to clean the accumulated impurities. The cleaning member 300 can include a scraper, a brush or a scraper. The material can be a wear-resistant, antistatic composite material to improve the cleaning efficiency and avoid secondary attachment. The flow guide assembly 400 includes a driving member 410 and an impeller 420. The driving member 410 is used to drive the impeller 420 to rotate. When the impeller 420 rotates, a local negative pressure can be formed near the cleaning area, thereby generating a drainage airflow, which can promptly remove the dust and particles removed by the cleaning member 300, and effectively prevent the re-deposition of impurities after cleaning. The transmission assembly 500 is used to connect the flow guide assembly 400 and the cleaning member 300, and can convert the rotational motion of the impeller 420 into the reciprocating linear motion of the cleaning member 300, thereby realizing the 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 duct machine 600 is working normally, the self-cleaning filter mechanism can work in conjunction with the fan, or can be started regularly or on demand through the preset control logic. When it is detected that the resistance of the filter element 200 increases or the operating time exceeds the limit, the system controller can start the driving element 410, drive the impeller 420 to form a negative pressure suction force, and at the same time drive the cleaning element 300 to perform reciprocating scraping through the transmission component 500 to achieve automatic cleaning of the filter element 200. With the appropriately designed air flow channel, the cleaned impurities can be introduced into the dust collection area, and can be cleaned regularly and concentratedly later.

[0056] The transmission assembly 500 realizes a multi-functional collaborative effect under the action of a power source. Through the above structural settings, when the driving member 410 works, on the one hand, the impeller 420 provides a negative pressure airflow to suck dust, and on the other hand, its rotation also drives the cleaning member 300 to reciprocate and clean through the transmission assembly 500, realizing the "sucking and brushing" of the filtering mechanism. The two functions cooperate synchronously and complement each other, significantly improving the filtering efficiency and self-cleaning ability. Specifically, when the driving member 410 works, the rotation of the impeller 420 not only generates suction to remove the impurities cleaned by the cleaning member 300, but also drives the cleaning member 300 to scrape the filtering member 200 through the transmission assembly 500, simultaneously realizing the dual functions of scraping the filtering member 200 and discharging impurities in the self-cleaning process. The actions of the diversion assembly 400 and the cleaning member 300 are not independent of each other, but form a coordinated linkage relationship under the coordination of the transmission assembly 500, that is, a power source simultaneously drives two functional modules to complete complementary cleaning actions, thereby significantly improving the cleaning efficiency and dust removal effect. The self-cleaning filtering mechanism is not only compact in structure and high in automation, but also through the design of the transmission assembly 500, the diversion assembly 400 and the cleaning member 300 form a synergistic effect, so as to achieve multiple functions with the simplest power source, and has extremely high practical value and promotion prospects in air treatment systems such as the air duct machine 600.

[0057] In some embodiments, the transmission assembly 500 includes a crank member 510, a connecting rod 520, and a sliding member 530. The support member 100 is provided with a first sliding groove 121 extending in a first direction. The sliding member 530 is slidably connected to the first sliding groove 121. One end of the connecting rod 520 is rotatably connected to the crank member, and the other end of the connecting rod 520 is rotatably connected to the sliding member 530. The diversion assembly 400 drives the crank member 510 to rotate, and the sliding member 530 is used to drive the cleaning member 300 to reciprocate and slide.

[0058] The support member 100 is provided with a first sliding groove 121 extending in the first direction, which is used to guide the cleaning member 300 to perform a linear reciprocating motion on the surface of the filter member 200. The sliding member 530 is slidably connected in the first sliding groove 121, and its moving direction is the same as the cleaning path of the cleaning member 300. The cleaning member 300 can be fixedly installed on the sliding member 530 and move together with the sliding member 530. One end of the connecting rod 520 structure 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 therewith, and drives the sliding member 530 to reciprocate linearly in the sliding groove through the connecting rod 520. This linear motion drives the cleaning member 300 to sweep back and forth on the surface of the filter member 200, thereby continuously removing adhered impurities such as dust and hair. This structure enables the rotational motion of the flow guiding assembly 400 to be naturally coupled with the reciprocating linear motion of the cleaning member 300, without the need to add auxiliary actuating mechanisms such as electromagnetic push rods, cylinders or motors, simplifies the overall machine design, and also improves the service life and system stability.

[0059] In some embodiments, the transmission assembly 500 further includes a first gear 540 and a gear rod 550. Second gears 560 and third gears 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 and connected with the first gear 540. The third gear 570 is meshed and connected with the crank member 510.

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

[0061] In this embodiment, the power source is still the driving member 410. The entire transmission system forms a complete power chain of gear meshing - eccentric crank - connecting rod 520 - sliding member 530 under its drive, and realizes the precise conversion of rotational motion to linear reciprocating motion structurally. The gear structures at all levels in the transmission assembly 500 are meshed tightly and the structure is compact, which can make full use of the energy during the rotation of the impeller 420. While the flow guiding assembly 400 generates air flow to adsorb impurities, the cleaning member 300 is actively wiped by the same power source, effectively improving the cleaning effect.

[0062] In some embodiments, a flow guiding cavity 122 is formed in the support member 100, and the impeller 420, the first gear 540, the second gear 560 and the end of the gear rod 550 where the second gear 560 is arranged are located in the flow guiding cavity 122. On the one hand, the flow guiding cavity 122 is used to define the flow path of the air flow and serve as the path for dust impurities to be discharged; on the other hand, by means of the gear rod 550, the first gear 540 inside the flow guiding cavity 122 is connected to the crank member 510 outside the flow guiding cavity 122. While realizing power transmission, the structures such as the crank member 510, the connecting rod 520 and the sliding member 530 do not need to be placed in the flow guiding cavity 122 and are not affected by dust impurities.

[0063] The diversion cavity 122 formed inside the support member 100 in the self-cleaning filtration mechanism is used to form a relatively enclosed air flow channel around components such as the impeller 420, thereby defining the air flow path and providing a protective space for the diversion component 400 and part of the transmission structure structurally. Specifically, part of the structures of the impeller 420, the first gear 540, the second gear 560, and the gear rod 550 are provided inside the diversion cavity 122. Among them, the second gear 560 is arranged at one end of the gear rod 550, and this end is located inside the diversion cavity 122, meshed and connected with the first gear 540, and transmits power to the third gear 570 and the crank member 510 outside the diversion cavity 122 by means of the gear rod 550. In the first aspect, the diversion cavity 122 itself, as an independent and enclosed channel space, can effectively guide the air flow direction when used in cooperation with the impeller 420, ensuring that pollutants such as dust and impurities swept by the cleaning member 300 are discharged along a preset path, avoiding accumulation inside the structure, and ensuring the cleaning efficiency of the filter member 200. In the second aspect, by passing the gear rod 550 through the wall of the diversion cavity 122 to connect the rotational drive structure inside the diversion cavity 122 with the crank assembly outside the diversion cavity 122, while effectively transmitting power, mechanisms that are more sensitive to dust such as the crank member 510, the connecting rod 520, and the sliding member 530 are arranged outside the diversion cavity 122. This structural arrangement not only effectively prevents dust from causing wear and jamming at the hinge joints of the sliding member 530 and the connecting rod 520, but also facilitates subsequent maintenance and repair. All in all, this structure not only improves the integration and protection of the diversion component 400, but also achieves a balance among cleaning efficiency, reliability, and maintenance convenience through the spatial separation design of the diversion cavity 122 and part of the transmission component 500, fully reflecting the technical advantages of the mechanical system in terms of multi-functional integration and working environment adaptability.

[0064] In some embodiments, a collection groove 130 for collecting the filter residues removed by the cleaning member 300 is provided on the support member 100. A dust collection box 140 is also provided on the support member 100. The diversion cavity 122 is respectively communicated with the collection groove 130 and the dust collection box 140. The impeller 420 is used to generate an air flow to drive the filter residues in the dust collection box to be transferred into the dust collection box 140 through the diversion cavity 122.

[0065] The collection tank 130 is generally arranged at a position below the filter element 200, and is used to receive and temporarily store pollutants such as dust and impurity particles scraped or brushed off by the component to be cleaned 300, preventing them from falling back into the air flow channel of the air duct machine 600 or adhering to the surfaces of other structures. The dust collection box 140 provided by the support member 100 is used to centrally store the pollutants in the collection tank 130. The diversion cavity 122 is respectively communicated with the collection tank 130 and the dust collection box 140. Among them, the diversion cavity 122 constructs an air flow transmission path through the air inlet arranged on one side of the collection tank 130 and the air outlet arranged on one side of the dust collection box 140. During the operation of the system, the impeller 420 is driven to rotate by the driving member 410, generating a suction air flow. This air flow flows along the diversion cavity 122 and forms a suction effect on the dust and impurities in the collection tank 130, so as to transport the pollutants to the dust collection box 140 through the diversion cavity 122 for centralized collection. This process does not rely on an additional power device, and only uses the air flow generated by the impeller 420 of the diversion component 400 itself to complete the transfer of the filter, thus simplifying the structure and reducing energy consumption. That is, through the flow channel connection of the diversion cavity 122 with the collection tank 130 and the dust collection box 140, the "collection - transfer - convergence" process of pollutants can be completed synchronously during the cleaning process, improving the overall cleaning efficiency of the system. In addition, the pollutants are directly guided from the collection tank 130 to the dust collection box 140 by the diversion air flow, preventing them from staying near the filter element 200 or being re-involved in the air channel, effectively improving the air quality. By integrating the collection tank 130, the dust collection box 140 and the corresponding diversion structure on the support member 100, all the filter treatment paths are completed within the framework of the support member 100, avoiding external complex pipelines and making the structure more compact. Optionally, the dust collection box 140 can be designed as a detachable structure for easy regular cleaning.

[0066] In some embodiments, two cleaning members 300 are provided and respectively adhered to the surfaces on opposite sides of the filter member 200. That is to say, cleaning members 300 are provided on both the air inlet side and the air outlet side of the filter member 200. This structural design enables effective removal of dust or impurities accumulated in any direction during the operation of the filter member 200 through the corresponding cleaning member 300 on one side. Specifically, each cleaning member 300 is configured to reciprocate in a first direction, so as to maintain a fitting contact with the corresponding side filter surface during the movement, so as to scrape or brush off the pollutants attached to the filter surface. The two cleaning members 300 can be driven synchronously, or can be designed to move alternately or be independently controlled according to actual needs. This double-sided cleaning structure has the following technical advantages compared with single-sided cleaning: First, the pollution sources on the air inlet side and the air outlet side are different. For example, the air inlet side is more likely to be attached with coarse particulate dust, and the air outlet side may be attached with fine suspended matter or condensates. By providing double-sided cleaning members 300, it can be ensured that the entire filter surface can be effectively cleaned in any working state; Second, both sides of the filter member 200 are kept clean, avoiding an increase in pressure difference caused by long-term accumulation of pollutants on one side, which is beneficial to extending the effective service life of the filter member 200. The resistance of the cleaned filter surface is smaller, which helps to maintain a stable air flow rate in the system and the energy efficiency of the air-conditioning system; Third, the double cleaning path can still work on the other side after one side cleaning member 300 fails or wears, which has a certain redundancy and improves the reliability of the system. Therefore, this embodiment realizes a more efficient and comprehensive automatic cleaning effect by providing independent cleaning members 300 on both sides of the filter member 200 and combining synchronous or independent control movement modes, and is particularly suitable for scenarios with high requirements for air filtration accuracy and operation stability such as air duct machines 600.

[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. 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 arranged 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 end and the third end 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 a first direction. The first slider 532 and the second slider 533 are respectively slidably connected to two parallel first slide grooves 121 set on the support member 100, and each slider is fixedly connected to the cleaning member 300 on the corresponding side. Therefore, under the drive of the transmission assembly 500, the two cleaning members 300 can achieve synchronous and consistent reciprocating sliding to remove attachments on the air inlet and air outlet side surfaces of the filter element 200. The Y-shaped connecting rod 531 distributes the driving force of the end of a connecting rod 520 to the two cleaning members 300 in a reasonable manner, avoiding the complex arrangement problem caused by setting two independent transmission paths; the two cleaning members 300 move synchronously under the drive of the sliding member 530, avoiding the displacement or deformation of the filter 200 due to uneven force during the cleaning process, and the movement is symmetrical and stable; the coordinated movement of the two cleaning members 300 is achieved through a power transmission path, which simplifies the overall mechanical structure and facilitates assembly and maintenance; the two cleaning members 300 work at the same time, which can significantly shorten the single cleaning cycle and improve the self-cleaning response speed. Therefore, this embodiment realizes the coordinated driving of the cleaning members 300 on both sides of the filter 200 by introducing the design of the sliding member 530 of the Y-shaped connecting structure, which not only ensures the cleaning efficiency but also improves the reliability and maintainability of the overall structure, and is particularly suitable for air conditioning equipment with high requirements for filtering efficiency and operation continuity.

[0069] In some embodiments, the cleaning member 300, the guide assembly 400 and the transmission assembly 500 are each provided with two groups, and are arranged in sequence along the first direction, the two groups of the guide assembly 400 are both located in the middle of the first direction, and the two groups of the transmission assembly 500 are both located at both ends of the first direction. The two groups of the guide assembly 400 are both located in the middle of the first direction, and the two groups of the transmission assembly 500 are respectively located at both ends of the first direction, forming a structural configuration of "middle dust suction, two-end drive" in terms of layout.

[0070] Each set of guide components 400 is opposite to its corresponding two cleaning members 300, and the guide components 400 include a driving member 410 and an impeller 420, which are used to provide suction while the cleaning members 300 remove impurities, and to remove the impurities through the guide cavity 122 and introduce them into the dust collection box 140. The two sets of guide components 400 are located in the middle, which is conducive to constructing a left-right symmetrical dust collection path, realizing the nearby suction of the cleaning objects, and improving the 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 at the middle position in the first direction and are used to generate suction to remove the impurities removed by the cleaning element 300. The two sets of transmission components 500 are respectively located at both ends in the first direction. Each set of transmission components 500 can respectively control the synchronous cleaning actions of the two cleaning elements 300 on the air inlet side and the air outlet side of the filter element 200. That is, the connecting rod 531 of the sliding member 530 of each set of transmission components 500 can be in a Y shape, with one end connected to the connecting rod 520, and the other two ends are respectively connected to the cleaning elements 300 on the air inlet side and the air outlet side of the filter element 200 through the first slider 532 and the second slider 533. Since the two sets of transmission components 500 are arranged at both ends in the length direction of the filter element 200, a symmetric distribution structure is formed with the flow guiding components 400 arranged in the middle, thereby effectively shortening the displacement path of the cleaning elements 300 driven by each set of transmission components 500, reducing the structural load and energy consumption, and improving the motion response speed and efficiency.

[0072] In addition, the structural design of dust collection in the middle and driving at both ends not only improves the cleaning efficiency but also optimizes the distribution of the cleaning path and the dust flow guiding path in the filtering area. Only one flow guiding cavity 122 can be designed in the middle below the middle support member 100. The impellers 420 of the two sets of flow guiding components 400 and the first gears 540 of the two sets of transmission components 500 are all located in the same flow guiding cavity 122. Transmission cavities 123 are respectively arranged on both sides of the flow guiding cavity 122. The fixed third gears 570, crank members 510, connecting rods 520, and sliding members 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 guiding cavity 122 and the transmission structures in the transmission cavities 123 on both sides are transitionally connected through the gear rods 550 of the two sets of transmission components 500. The setting of the middle flow guiding cavity 122 is beneficial to concentrating the dust guiding path and enhancing the dust collection efficiency. The distributed transmission cavities 123 on both sides avoid the centralized arrangement of complex mechanisms, improve the structural stability and maintenance convenience; by modularly arranging the first gears 540, gear rods 550, third gears 570, crank members 510, etc. in different functional cavities, the risk of the transmission structure being invaded by dust is reduced and the reliability is enhanced.

[0073] In some embodiments, the support member 100 includes a fixed part 110 and a bottom bin 120 arranged up and down. The filter element 200 is a filter screen arranged on the fixed part 110. A receiving cavity is arranged in the bottom bin 120, and the transmission component 500 and the flow guiding component 400 are arranged in the receiving cavity.

[0074] The filter element 200 is a filter screen disposed on the fixed part 110 for intercepting dust and impurities in the air flow; the bottom bin 120 is disposed below the filter element 200, and an accommodation cavity for installing various functional components is formed inside it. Specifically, the accommodation cavity includes the diversion cavity 122 and the transmission cavity 123 mentioned in the foregoing embodiments, which are respectively used for arranging the dust collection and power transmission functional modules. The diversion component 400 and the transmission component 500 are both disposed in this accommodation cavity. Among them, the diversion cavity 122 is located in the middle of the bottom bin 120 and is used for accommodating the impeller 420 and the first gear 540 arranged coaxially therewith. On the one hand, the diversion cavity 122 defines the air flow arrangement path, facilitating the centralized export of impurities removed by the cleaning member 300 under the action of the air flow. On the other hand, it provides a sealed space to isolate the intrusion of dust on the transmission structure. The transmission cavity 123 is disposed on both sides of the diversion cavity 122 and is respectively used for installing the second gear 560, the third gear 570, the crank member 510, the connecting rod 520 and the sliding member 530 in the transmission component 500. The structure of this embodiment has clear structural partitions, and the fixed part 110 and the bottom bin 120 are distributed up and down, which helps to organically distinguish the filtering function and the driving cleaning function, facilitates modular design and assembly. The diversion component 400 and the transmission component 500 are integrated in the accommodation cavity of the bottom bin 120, and the overall structure is compact, reducing the installation volume. The transmission parts and the dust collection parts are arranged in separate cavities, avoiding wear and jamming of the transmission mechanism caused by dust, and also facilitating later maintenance, cleaning or replacement operations.

[0075] In some embodiments, an opening 111 for inserting or removing the filter screen is provided at one end of the fixed part 110 away from the bottom bin 120. This opening 111 provides convenience for the installation and maintenance of the filter element 200. Users can achieve quick disassembly, installation and replacement of the filter screen through this opening 111 without disassembling the entire support structure.

[0076] Specifically, the opening 111 can be provided at the top of the fixed part 110, and the filter screen can be slidably or pull-out mounted inside the fixed part 110. By providing the opening 111 on the fixed part 110, the filter screen can be replaced or cleaned without disassembling the whole machine or other key components, improving the maintainability of the whole machine and the user experience. It is especially suitable for air filtration scenarios that require regular cleaning of dust and impurities, such as air duct machines 600, central air conditioning return air vents, purification devices and other equipment. In order to fix the filter element 200, one or more first fixing holes 112 are provided on the fixed part 110, preferably corresponding to the corners of the filter element 200, for assisting in fixing the filter element 200. For example, the first fixing hole 112 can be a threaded hole, and a countersunk head screw can be used to cooperate with the threaded hole for fixed connection.

[0077] In some embodiments, the cleaning member 300 includes a cleaning portion 310 and a driving portion 320 connected to each other. The bottom bin 120 has a top wall 124 connected to the fixing portion 110. On a side of the top wall 124 facing the fixing portion 110, a second chute 125 extending along the first direction is formed. The driving portion 320 is slidably engaged with the second chute 125. On a side of the top wall 124 located in the accommodation cavity, a first chute 121 is formed. The first chute 121 communicates with the second chute 125 to enable connection between the sliding member 530 and the driving portion 320.

[0078] The driving portion 320 is configured to receive a driving force from the transmission assembly 500. The driving portion 320 is disposed in the second chute 125 and is slidably engaged therewith to perform a reciprocating linear movement in the first direction, thereby driving the cleaning portion 310 to wipe the filter member 200 reciprocally. The first chute 121 communicates with the second chute 125, so that the sliding member 530 disposed in the accommodation cavity can pass through the first chute 121 and be connected to the driving portion 320, and further transmit the movement of the connecting rod 520 driven by the crank member 510 to the driving portion 320, realizing a synchronous reciprocating cleaning action of the cleaning member 300. With the above structure, the cleaning member 300 can reciprocally slide in the length direction (i.e., the first direction) of the filter member 200. Cooperating with the air flow suction force provided by the diversion assembly 400, dust and impurities attached to the filter mesh can be effectively removed, improving the automatic cleaning ability and use convenience of the system.

[0079] In some embodiments, the support member 100 further includes a pulling portion 150 that is connected to both the fixing portion 110 and the bottom bin 120. The pulling portion 150 is located at one end of the support member 100 in the first direction. The edge of the pulling portion 150 protrudes from the fixing portion 110 and the bottom bin 120, forming an outer edge structure that facilitates positioning and installation during the overall insertion process. Specifically, the pulling portion 150 is configured to form a fixed connection with the structure of the air duct machine 600 after the entire self-cleaning filter mechanism including the fixing portion 110 and the bottom bin 120 is inserted into the installation space inside the air duct machine 600, for example, by means of buckles, screws, slide rail clamping, etc., so that the entire self-cleaning filter mechanism remains stable during use and avoids displacement or loosening. For example, one or more second fixing holes 151 are formed in the pulling portion 150 to assist in fixing the self-cleaning filter mechanism. The second fixing holes 151 can be threaded holes, and can be fixedly connected by countersunk head screws cooperating with the threaded holes.

[0080] The setting of this structure facilitates the modular installation, disassembly and maintenance of the self-cleaning filtering mechanism. While improving the product assembly efficiency, it also enables users or maintenance personnel to quickly complete component replacement or cleaning operations when needed. As an externally accessible part, the pulling part 150 can also be customized and optimized according to the overall machine structure to adapt to the interface structures of different models of air duct machines 600, enhancing the product versatility and adaptability.
