Description

Technical Field

[0001] This invention belongs to the field of clothing processing technology, and specifically discloses a lint filter device and a clothing processing device. Background Technology

[0002] A clothes dryer is a clothing treatment device used to dry clothes. As market demand continues to become more refined, clothes dryers are becoming more and more functional. For example, there are now clothes dryers with aromatherapy functions. When drying clothes, the aromatherapy is released through airflow and reaches the clothes, bringing a fragrance effect to the clothes as they dry.

[0003] In existing dryers with aromatherapy functions, the aromatherapy box is usually installed inside the lint filter or at the top opening of the lint filter. This causes the airflow containing lint to first pass through the aromatherapy box before being filtered by the filter screen.

[0004] In other words, the way existing aromatherapy boxes are set up with the lint filter inevitably leads to lint easily entering the interior of the aromatherapy box, causing blockage, contaminating the aromatherapy medium, affecting the normal use of the aromatherapy function, and making the aromatherapy box difficult to clean. Summary of the Invention

[0005] The purpose of this invention is to provide a lint filtering device and a clothing treatment device. The advantage of this structure is that lint can be filtered through the filter screen first, so as to avoid or reduce the clogging and contamination of the container used to hold the medium by lint, ensure the normal use of the aromatherapy function, reduce the cleaning frequency of the container holding the medium, and improve the user experience.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A lint filtering device includes a filter support, a filter screen, and a media box. The filter screen includes an outer filter screen covering the two opposite outer sides of the filter support and an inner filter screen disposed inside the filter support. The inner filter screen surrounds a receiving space with a lower opening. The inner filter screen, the filter support, and the outer filter screen surround a lint receiving cavity with an upper opening. The lint receiving cavity and the receiving space are located on the inner and outer sides of the inner filter screen, respectively. The media box is detachably disposed in the receiving space and has ventilation holes.

[0008] As an optional technical solution for a lint filtration device, the filter support has an inner partition rib located in the accommodating space, and the media box is provided with a plurality of ventilation holes. The media box is slidably connected to the filter support so that the inner partition rib selectively blocks some or all of the ventilation holes.

[0009] As an optional technical solution for a lint filtration device, the accommodating space has a side opening formed on at least one side of the filter support along its length, and the media box can be inserted into the accommodating space through the side opening.

[0010] As an optional technical solution for a lint filtering device, the ventilation holes are located on at least one side of the media box facing the inner filter screen.

[0011] As an optional technical solution for a lint filtering device, the filter support has an inner filter support, which has a V-shaped or U-shaped structure with the opening facing downwards. The inner filter screen is covered on the outside of the inner filter support, and the media box is disposed on the inside of the inner filter support, and the media box is slidably connected to the inner filter support.

[0012] As an optional technical solution for a lint filtration device, the top, bottom, and opposite sides of the media box are all slidably abutted against the inner filter support.

[0013] As an optional technical solution for a lint filtering device, the two lower ends of the inner filter bracket can be unfolded or closed relative to each other. The filter bracket also includes an outer filter bracket, which includes two outer half-boxes arranged opposite to each other. The inner filter bracket is disposed between the two outer half-boxes, and the lower end of each outer half-box is rotatably connected to the lower end of the corresponding inner filter bracket. The upper ends of the two outer half-boxes can be snapped together or unfolded relative to each other. The outer surface of each outer half-box is covered with the outer filter screen.

[0014] As an optional technical solution for a lint filtration device, the upper ends of the two outer half-boxes are joined together, the lower ends of the outer half-boxes are opened relative to each other to form an installation space with a lower opening, and the inner filter bracket is located in the installation space.

[0015] As an optional technical solution for a lint filter device, the two side plates of the outer half-box are provided with installation notches. The installation notches of the two outer half-boxes together form an installation port with a lower opening. The installation port forms a lateral opening of the installation space. The outer surface of the inner filter bracket is in contact with the side wall of the installation port.

[0016] As an optional technical solution for a lint filtration device, the two outer half-boxes have the same structure; and / or, the inner filter support has a symmetrical structure.

[0017] As an optional technical solution for a lint filtering device, the tops of the two outer half-boxes are detachably connected; and / or, the inner filter support includes two inner frame bodies connected at their upper ends and capable of being opened or closed relative to each other at their lower ends, with the lower ends of the two inner frame bodies detachably connected.

[0018] As an optional technical solution for a lint filtering device, one of the inner frames is provided with a snap-fit ​​component, and the other inner frame is provided with a snap-fit ​​slot. The snap-fit ​​component extends toward the other inner frame and snaps into the snap-fit ​​slot.

[0019] As an optional technical solution for a lint filtration device, two snap-fit ​​components are provided at intervals along the length of the inner filter support, and the media box is located between the two snap-fit ​​components.

[0020] A garment processing device includes a lint filter as described above.

[0021] The beneficial effects of this invention are as follows:

[0022] The lint filter provided by this invention, by setting a media box inside the filter support, allows the media box to be used to store volatile media with aromatherapy or disinfection functions, meeting the user's needs for the media. Simultaneously, because the media box is located within the accommodating space surrounded by the inner filter screen, lint entering the lint filter is difficult to reach the media box due to the obstruction of the inner filter screen, effectively avoiding or reducing lint clogging of the media box and lint contamination of the media, ensuring the normal and effective use of the media, and reducing the difficulty and frequency of cleaning the media box. Furthermore, because the lint filter has both an inner and outer filter screen, it can effectively increase the area of ​​the filter screen, improving the effect of lint removal.

[0023] The clothing processing device provided by the present invention, by employing the above-mentioned lint filter device, can reduce the frequency of lint cleaning and improve the user experience. Attached Figure Description

[0040] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and not intended to limit it. Furthermore, it should be noted that, for ease of description, the accompanying drawings show only the parts relevant to the present invention, and not all of the structures.

[0041] In the description of this invention, unless otherwise explicitly specified and limited, the terms "connected," "linked," and "fixed" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0042] In this invention, unless otherwise explicitly specified and limited, "above" or "below" the second feature can include direct contact between the first and second features, or contact between the first and second features through another feature between them. Furthermore, "above," "over," and "on top" of the second feature includes the first feature directly above or diagonally above the second feature, or simply indicates that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature includes the first feature directly below or diagonally below the second feature, or simply indicates that the first feature is at a lower horizontal level than the second feature.

[0043] In the description of this embodiment, the terms "upper," "lower," "right," etc., refer to the orientation or positional relationship shown in the accompanying drawings. They are used only for ease of description and simplification of operation, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on the present invention. In addition, the terms "first" and "second" are used only for distinction in description and have no special meaning.

[0044] Specifically, the garment handling device includes a housing 700, a drum 600 disposed inside the housing 700, and a heat pump system disposed between the housing 700 and the drum 600. An air duct is formed between the inner wall of the housing 700 and the outer wall of the drum 600. The heat pump system is disposed within the air duct. The housing 700 has an air inlet at the front opening of the drum 600, communicating with the air duct, and an air outlet at the rear end of the drum 600. The heat pump system includes a compressor 400, a condenser 300, a throttling device 800, an evaporator 200, and a drying fan 900. The evaporator 200, condenser 300, and drying fan 900 are arranged sequentially along the airflow direction. The compressor 400, condenser 300, throttling device 800, and evaporator 200 are sequentially connected by pipes to form a refrigerant circulation pipeline, which is filled with refrigerant.

[0045] When the heat pump system is running, the compressor 400 pressurizes and heats the refrigerant and sends it to the condenser 300. The high-temperature refrigerant exchanges heat with the air in the duct at the condenser 300 and is converted into a low-temperature, low-pressure gas. The low-temperature, low-pressure gas is then transported to the evaporator 200 after passing through the throttling device 800. After entering the evaporator 200, it absorbs the heat from the high-temperature, humid gas flowing across the surface of the evaporator 200, heats up, and flows back to the compressor 400, completing the refrigerant flow cycle. Meanwhile, under the action of the drying fan 900, the airflow in the duct enters the drum 600 through the duct outlet. When the high-temperature gas passes through the drum 600, it comes into contact with the damp clothes and becomes humid and hot gas. The humid and hot gas enters the duct through the duct inlet and is blown toward the evaporator 200. At the evaporator 200, it exchanges heat with the low-temperature cold medium. The humid and hot gas is condensed and dehumidified to form dry air. After passing through the condenser 300, the dry air exchanges heat with the high-temperature cold medium in the condenser 300 to form high-temperature dry air. The high-temperature dry air continues to flow and re-enters the drum 600 through the duct outlet, forming an airflow circulation. The air circulation carries away the moisture in the clothes, thus drying them.

[0046] In this embodiment, since the hot and humid air is condensed and cooled in the evaporator 200, forming condensate, a water collection tray 500 is also provided in the air duct to collect the condensate. In this invention, the housing 700, the drum 600, and the heat pump system can all be configured with reference to existing technology, and will not be described in detail here.

[0047] In this embodiment, to prevent lint from clothing from entering the air duct with the airflow, a lint filter 100 is provided at the air inlet of the air duct to collect the lint flowing out of the roller 600. The lint filter 100 includes a filter bracket and a filter screen disposed on the filter bracket. The filter bracket is used to install the filter screen and realize the installation of the lint filter 100 on the housing 700. The filter screen is used to filter and collect the lint entering the filter bracket, preventing the lint from continuing to flow with the airflow.

[0048] like Figure 2 and Figure 3 As shown, the lint filtering device provided in this embodiment includes a filter support, a filter screen, and a media box 4. The filter screen includes an outer filter screen covering the two opposite outer sides of the filter support and an inner filter screen disposed inside the filter support. The inner filter screen surrounds a receiving space with a lower opening. The inner filter screen, the filter support, and the outer filter screen surround a lint receiving cavity with an upper opening. The receiving space is located outside the lint receiving cavity. The media box 4 is detachably disposed in the receiving space. The media box 4 is provided with ventilation holes 43.

[0049] The lint filter device provided in this embodiment, by setting a media box 4 inside the filter support, allows the media box 4 to store volatile media with aromatherapy or disinfection functions, meeting the user's needs for the media. Simultaneously, because the media box 4 is located within the accommodating space surrounded by the inner filter screen, lint entering the lint filter device is prevented or minimized from entering the media box 4 due to the obstruction of the inner filter screen, effectively preventing the media box 4 from being clogged by lint and preventing lint from contaminating the media, ensuring the normal and effective use of the media, and reducing the difficulty and frequency of cleaning the media box 4. Furthermore, because the lint filter device has both an inner and outer filter screen, it can effectively increase the area of ​​the filter screen, improving the effect of lint removal.

[0050] Furthermore, the filter support has an inner partition rib 1112 located within the accommodating space. The media box 4 has several ventilation holes 43. The media box 4 is slidably connected to the filter support, allowing the inner partition rib 1112 to selectively block some or all of the ventilation holes 43. This arrangement allows adjustment of the media box 4's position on the filter support, enabling the inner partition rib 1112 to selectively block some of the ventilation holes 43 on the media box 4, thereby regulating the concentration of media evaporation and improving the user experience.

[0051] To facilitate the assembly and disassembly of the lint filter, preferably, such as Figure 1 and Figure 2As shown, the filter support includes an outer filter support 2 and an inner filter support 1. The inner filter support 1 includes two inner frame bodies 11 connected at the top and whose lower ends can be opened or closed relative to each other. The outer filter support 2 includes two outer half-box bodies 21 that are opposite to each other and spaced apart. The two outer half-box bodies 21 are located on both sides of the two inner frame bodies 11, and the lower ends of the two outer half-box bodies 21 are rotatably connected to the corresponding inner frame body 11. The top ends of the two outer half-box bodies 21 can be fastened or separated relative to each other. An inner filter screen is covered on the first side of the inner filter support 1, and a media box 4 is located between the two inner frame bodies 11. Each outer half-box body 21 is provided with an outer filter screen. The first side is the side of the inner filter support 1 facing the outer filter screen.

[0052] This type of lint filter, by setting an inner filter support 1 and an outer filter support 2, with both the inner filter support 1 and the outer filter support 2 used to house filter screens, can increase the area of ​​the filter screen while maintaining the overall external dimensions of the lint filter, thereby increasing the filtration area and improving the lint collection capacity of the lint filter, thus reducing the cleaning frequency of the lint filter and improving the user experience. At the same time, by connecting the upper end of the inner frame 11 and the lower end of the inner frame 11 to the lower end of the outer half-box 21, the entire lint filter can be easily unfolded when cleaning the lint filter, thereby improving the cleaning convenience of the lint filter. It also facilitates the folding and assembly of the lint filter after cleaning, improving the disassembly and assembly convenience and cleaning efficiency of the lint filter.

[0053] In other embodiments, the outer filter support 2 may also adopt other existing structural forms, and the connection between the inner filter support 1 and the outer filter support 2 may also adopt other existing connection structures.

[0054] like Figure 2 , Figure 3 and Figure 5 As shown, the opening of each outer half-box 21 faces the other outer half-box 21. Each outer half-box 21 includes an outer filter plate portion 212 for installing an outer filter screen, a box top plate 211 connected to the top of the outer filter plate portion 212, box side plates 214 connected to opposite sides of the outer filter plate portion 212, and a box bottom plate 213 connected to the bottom of the outer filter plate portion 212. The upper and lower ends of the box side plates 214 are connected to the box top plate 211 and the box bottom plate 213, respectively. The box top plate 211, outer filter plate portion 212, box side plates 214, and box bottom plate 213 enclose a box space with an opening facing the other outer half-box 21.

[0055] The top plate 211 is preferably an upward-opening arc-shaped structure to accommodate the shape of the air inlet in the air duct. Each top plate 211 has several filter air inlets 2111 to ensure sufficient airflow while minimizing the size of each individual filter air inlet 2111. This improves structural strength and prevents wire debris from the wire debris collection cavity from flying out of the wire debris filtering device through the filter air inlets 2111. Preferably, the filter air inlets 2111 are arranged in multiple rows along the circumference of the arc-shaped structure, with each row having several filter air inlets 2111 along the radial direction of the arc-shaped structure to improve processing convenience. The filter air inlets 2111 are preferably elongated holes, which facilitate the passage and settling of wire debris, ensuring sufficient collection of wire debris within the collection cavity.

[0056] The top plate 211 extends outward along the outer side of the outer filter plate 212 and the side plate 214 of the box and forms a raised edge 216. The raised edge 216 can be placed at the opening end face of the air inlet of the air duct to facilitate the installation of the lint filter device at the air inlet of the air duct.

[0057] To further facilitate the assembly and disassembly of the lint filter, each top plate 211 is provided with a pick-and-place port 218, and the pick-and-place ports 218 on the two top plates 211 are directly opposite each other. Each outer filter plate 212 has a handle 217 extending from its top end toward the other outer filter plate 212, with the two handles 217 facing each other and located within the pick-and-place port 218. The pick-and-place port 218 and the handle 217 allow users to pick up and place the lint filter at the air inlet of the duct by gripping the handle 217, improving the ease of assembly and disassembly of the lint filter.

[0058] Because the opening 218 divides the top plate 211 into two parts, reinforcing ribs 219 are provided on the inner surface of the top plate 211 to ensure its structural strength. Preferably, several reinforcing ribs 219 are spaced apart along the circumference of the top plate 211, and the reinforcing ribs 219 are located between two adjacent rows of filter inlets 2111. Furthermore, reinforcing ribs 219 are also provided at the edge of the opening 218 to further enhance the local structural strength of the outer half of the box 21 at the opening 218.

[0059] To ensure the stability of the lint filter after assembly, the upper ends of the two outer half-boxes 21 are detachably connected, and the connection method can be snap-fit, screw-fit, or plug-in. Preferably, in this embodiment, the two handles 217 have through holes 2171 extending through opposite sides of the outer half-boxes 21, and the two outer half-boxes 21 are connected by connecting rods passing through the two through holes 2171. This connection method allows the two handles 217 to adopt the same structure, simplifying the processing of the outer filter bracket 2. In other embodiments, one handle 217 may have a through hole 2171, and the other handle 217 may have a threaded hole, using a threaded connector to achieve the connection between the two.

[0060] An external vent 2121 is provided on the external filter plate portion 212, and an external filter screen is covered on the external vent 2121. Preferably, two external vents 2121 are provided at intervals along the length of the external filter plate portion 212, and the portion of the external filter plate portion 212 between the two external vents 2121 forms an external partition rib 2122. This reduces the size of a single external filter screen while ensuring the effective filtration area of ​​the external filter screen, thereby reducing the cost of the external filter screen. At the same time, it also avoids the problem that the structural strength of the external filter plate portion 212 may be compromised due to an excessively large external vent 2121. Preferably, limiting ribs 215 protrude from both sides of the external vent 2121 on the external filter plate portion 212, and the limiting ribs 215 position the external filter screen. In other embodiments, the two external vents 2121 may also be covered by the same external filter screen. The installation method of the external filter screen on the external filter plate portion 212 can refer to the prior art, and will not be described in detail here.

[0061] After the wire lint filter is assembled, the side openings of the two outer half-boxes 21 are fitted together to prevent air leakage. To facilitate the installation of the inner filter bracket 1, the upper ends of the two outer half-boxes 21 are joined, while the lower ends of the outer half-boxes 21 are relatively open, forming an installation space with a lower opening. The inner filter bracket 1 is located within this installation space. This installation space allows for an increase in the length of the inner filter bracket 1 while maintaining the overall size of the outer filter bracket 2, thereby increasing the size of the inner filter screen and further increasing the filtration area. Furthermore, the installation space allows for better folding arrangements between the two components, increasing the overall length of the filter bracket 1 when unfolded.

[0062] Preferably, each side panel 214 has an installation notch 2141, which penetrates the lower end face of the side panel 214 and the side of the side panel 214 facing the other outer half-box 21. The installation notches 2141 of the two outer half-boxes 21 together form a downward-facing installation opening, which forms a lateral opening for the installation space. Both ends of the inner filter bracket 1 extend into the corresponding side installation opening and fit against the side wall of the installation opening. The installation opening can better limit the inner filter bracket 1 on the outer filter bracket 2 after the lint filter device is assembled, prevent the inner filter bracket 1 from shaking, and improve the assembly stability of the lint filter device. In other embodiments, the inner filter bracket 1 can also be completely set inside the outer filter bracket 2, that is, the side panels 214 of the two outer half-boxes 21 are completely fitted together.

[0063] In order to increase the contact area between the outer filter bracket 2 and the inner filter bracket 1, a raised rib is provided around the mounting notch 2141 on the inner surface of the box side plate 214, and the raised rib fits against the surface of the inner filter bracket 1.

[0064] like Figures 3-7 As shown, in this embodiment, the inner frame 11 and the outer half-box 21 are rotatably connected by a shaft connection structure 3. The shaft connection structure 3 includes a first connection structure 31 and a second connection structure 32. The first connection structure 31 has a shaft hole 314, and the second connection structure 32 has a rotating shaft portion 321, which rotatably passes through the shaft hole 314. The rotatable connection between the two is achieved through the rotational fit between the shaft and the hole, allowing for a wide range of rotation between them, and providing structural stability and a long service life. Preferably, at least two sets of shaft connection structures 3 are spaced apart along the length of the inner filter bracket 1 to improve the stability of the rotatable connection.

[0065] The first connecting structure 31 includes an upper seat 311, a semi-cylindrical part 312, and a connecting arc part 313: the upper seat 311 is connected to the outer half-box 21 or the inner frame 11; the upper end of the semi-cylindrical part 312 is connected to the side of the upper seat 311, and an arc-shaped opening 3121 is provided on the semi-cylindrical part 312; the inner surface of the connecting arc part 313 is a circular arc surface that is coaxial with the semi-cylindrical part 312 and has the same diameter, and the outer surface is a smooth curved surface. The connecting arc part 313 and the arc opening 3121 are provided in a one-to-one correspondence. The upper end of the connecting arc part 313 is connected to the upper seat 311, and the lower end of the connecting arc part 313 is connected to the lower inner surface of the semi-cylindrical part 312. The semi-cylindrical part 312 and the connecting arc part 313 together form a shaft hole 314.

[0066] The second connecting structure 32 includes a rotating shaft portion 321, a connecting rib portion 322, and an annular rib portion 323. The connecting rib portion 322 is connected to the outer half-box 21 or the inner frame 11. The connecting rib portion 322 is parallel to the axis of the rotating shaft portion 321 and connected to the outer wall surface of the rotating shaft portion 321. The annular rib portion 323 protrudes from the outer side of the rotating shaft portion 321 and is provided at intervals along the axial direction of the rotating shaft portion 321. One end of the annular rib portion 323 is perpendicularly connected to the connecting rib portion 322, and the other end of the annular rib portion 323 extends circumferentially along the rotating shaft portion 321 to the opposite side of the connecting rib portion 322 and extends upward to be flush with the upper end of the connecting rib portion 322.

[0067] The arrangement of the first connecting structure 31 and the second connecting structure 32 facilitates the opening of the upper and lower molds during processing, thereby simplifying the mold structure and improving the service life of the processing mold.

[0068] To facilitate the insertion of the rotating shaft portion 321 into the shaft hole 314, a chamfer 3211 is provided at the insertion end of the rotating shaft portion 321 to guide its entry into the shaft hole 314. Furthermore, an annular groove 3212 is provided near the insertion end of the rotating shaft portion 321, allowing the insertion end to undergo a certain deflection relative to the main structure of the second connecting structure 32. This further facilitates the insertion of the rotating shaft portion 321 into the shaft hole 314, improves the accuracy of the rotating shaft portion 321 during insertion, and enhances assembly convenience.

[0069] In this embodiment, each inner frame 11 is connected to the outer half-box 21 through two shaft connection structures 3, and the bottom ends of the inner frame 11 are respectively provided with a first connection structure 31 and a second connection structure 32, and the bottom ends of the outer half-box 21 are respectively provided with a second connection structure 32 and a first connection structure 31.

[0070] like Figure 8 and Figure 9 As shown, the inner frame 11 includes an inner filter plate portion 111, on which an inner ventilation opening 1111 is provided. The inner filter screen covers the two first sides and the top of the inner filter support 1, thereby covering the sides and top of the inner filter support 1. Preferably, two inner ventilation openings 1111 are provided at intervals along the length direction of the inner filter support 111 to reduce the size of a single inner ventilation opening 1111 and enhance the overall structural strength of the inner frame 11. The inner filter plate portion 111 between the two inner ventilation openings 1111 forms an inner partition rib 1112.

[0071] Preferably, a connecting plate portion 112 is connected to the lower end of the inner filter plate portion 111, and the connecting plate portion 112 is provided with the aforementioned first connecting structure 31 and second connecting structure 32. The connection plate portion 112 can reduce the thickness of the inner filter plate portion 111 while ensuring the stability of the first connecting structure 31 and the second connecting structure 32 on the inner frame 11.

[0072] The top ends of the two inner frame bodies 11 are connected by a flexible structure 12, and the flexible structure 12 is integrally formed with the inner frame bodies 11 to simplify the processing of the inner filter support 1. Specifically, the flexible structure 12 includes a connecting seat 121, which is an open ring structure with the opening facing downwards, and its two ends are respectively connected to the top ends of the two inner frame bodies 11. The thickness of the connecting seat 121 is less than the thickness of the inner frame body 11, and several connecting seats 121 are spaced apart along the length direction of the inner frame body 11.

[0073] The connecting seat 121 has a U-shaped structure with its opening facing downwards. The connecting seat 121 includes a top seat 1211 and two side seats 1212 connected to both ends of the top seat 1211. The two side seats 1212 are respectively connected to the inner frame 11. The thickness at the connection between the top seat 1211 and the side seats 1212 is less than the thickness of the rest of the structure, thereby ensuring the flexibility of the connecting seat 121 at corners and enabling relative unfolding between the top seat 1211 and the side seats 1212. In other embodiments, the connecting seat 121 can also be an arc-shaped structure.

[0074] At least two connecting seats 121 are provided at intervals along the length of the inner frame 1 to ensure the reliability of the connection between the two inner frame bodies 11. In this embodiment, three connecting seats 121 are provided, two of which are located at both ends of the inner frame body 11 along the length, and the other connecting seat 121 is located in the middle of the inner frame body 11 along the length and is directly opposite to the inner partition rib 1112.

[0075] Preferably, the outer surface of the side seat portion 1212 is smoothly connected to the outer surface of the inner filter plate portion 111 to reduce the sharp corners at the connection and avoid stress concentration.

[0076] More preferably, a reinforcing beam 122 connects two adjacent top seats 1211 to further enhance the overall structural strength of the inner filter bracket 1 and prevent deformation of the inner filter bracket 1 during assembly and use. Preferably, the top surface of the reinforcing beam 122 and the top surface of the top seat 1211 are on the same plane.

[0077] In other embodiments, the two inner frame bodies 11 can also be connected by a pivot structure or other hinge structure, which will not be described in detail in this embodiment.

[0078] like Figure 8 and Figure 10 As shown, in this embodiment, the lower end of the media box 4 is supported on the connecting plate portion 112 of the inner frame 11, thereby allowing the media box 4 to slide on the connecting plate portion 112. Preferably, the two opposite sides of the media box 4 are respectively attached to the inner surface (the side away from the outer filter screen) of the corresponding inner filter plate portion 111, thereby allowing the media box 4 to be stably clamped between the two inner frames 11, preventing the media box 4 from swaying left and right within the inner frame 11.

[0079] More preferably, the upper end of the media box 4 is slidably connected to the upper inner surface (the side away from the outer filter screen) of the inner filter bracket 1, thereby increasing the overall size of the media box 4 and allowing the upper and lower ends of the media box 4 to be sandwiched between the upper and lower ends of the inner filter bracket 1, further ensuring the stability of the media box 4 on the inner filter bracket 1 and preventing the media box 4 from shaking under wind pressure. More preferably, the projected outer contour of the media box 4 on a plane perpendicular to the length direction of the inner filter bracket 1 coincides with the projected contour of the inner surface of the inner filter bracket 1 on that plane, thereby effectively increasing the contact area between the media box 4 and the inner filter bracket 1 and improving the stability of the media box 4.

[0080] In this embodiment, the medium box 4 includes a box body 41 and a box cover 42. The box body 41 has a receiving groove with an opening on one side. The box cover 42 covers the opening of the receiving groove and surrounds the box body 41 to form a receiving cavity. The box body 41 and the box cover 42 are detachably connected. The detachable connection method can be snap-fit, threaded connection, or adhesive connection, etc. The specific structure of the detachable connection can adopt existing structures, which will not be described in detail here.

[0081] In this embodiment, the overall shape of the box body 41 is consistent with the inner surface shape of the inner filter support 1. That is, the upper end, opposite sides, and lower end of the box body 41 are all in contact with the inner filter support 1, and the aforementioned opening is provided on the side of the box body 41 perpendicular to the length direction of the inner filter support 1. This arrangement facilitates the processing of the box body 41 and improves the ease of assembly and disassembly of the box cover 42 and the box body 41. In other embodiments, the opening may also be formed on the side of the box body 41 facing the inner filter screen.

[0082] In this embodiment, the box body 41 includes two symmetrically arranged half-box portions 411, which are connected by welding or detachable connection. In other embodiments, the box body 41 may also be a one-piece molded structure, and the present invention does not impose specific limitations on this.

[0083] Preferably, the wall thickness of the box body 41 is approximately equal in all parts to facilitate the processing and forming of the box body 41.

[0084] To improve the structural stability of the wire lint filter after assembly, preferably, the lower ends of the two inner frame bodies 11 are detachably connected after assembly. This ensures that the lower ends of the two inner frame bodies 11 are relatively fixed, thus preventing the entire wire lint filter from unfolding and maintaining its overall stability.

[0085] Preferably, the two inner frame bodies 11 are snap-fitted together to facilitate the closure and disassembly of the inner frame bodies 11. Preferably, one inner frame body 11 is provided with a snap-fit ​​component 14, and the other inner frame body 11 is provided with a latch, into which the snap-fit ​​component 14 snaps.

[0086] Specifically, one inner frame 11 has an extension plate 141 protruding towards the other inner frame 11, and a hook 142 is provided at the end of the extension plate 141. The other inner frame 11 has a slot, and the hook 142 can be engaged into the slot, thereby connecting the two inner frame 11. Two snap-fit ​​members 14 are provided at intervals along the length of the inner filter bracket 1, and the media box 4 is located between the two snap-fit ​​members 14. This arrangement can achieve snap-fit ​​between the two inner frame 11 while ensuring that the media box 4 is limited between the two snap-fit ​​members 14, preventing the media box 4 from sliding out of the inner side of the lint filter device, and improving the installation stability of the media box 4.
