[0042] The filter screen comprises multiple filter modules arranged sequentially. Each filter module includes a filter support and a filter body mounted on the support. A magnetic structure is provided between the filter supports of every two adjacent filter modules, allowing them to be both connected and separated. The magnetic connection maintains the overall stability of the filter screen while enabling quick separation of the support during maintenance by demagnetizing or applying external force. This allows for the separate assembly and disassembly of the filter supports even in confined spaces, eliminating the need for complete filter screen disassembly and improving ease of use. It also reduces the requirements for tools and operating angles during filter screen assembly and disassembly. In cases of partial damage, only a single filter support needs to be replaced, significantly reducing maintenance difficulty. This addresses the problem of existing integrated filter screens requiring significant operating space and specialized tools for assembly and disassembly, making it inconvenient and hindering maintenance personnel from quickly cleaning or replacing the filter screen.

[0070] The following specific embodiments illustrate the implementation of the present invention. Those skilled in the art can easily understand other advantages and effects of the present invention from the content disclosed in this specification. Obviously, the described embodiments are only some, not all, of the embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0071] The terminology used in the embodiments of this invention is for the purpose of describing particular embodiments only and is not intended to limit the invention. The singular forms “a,” “the,” and “the” used in the embodiments of this invention and the appended claims are also intended to include the plural forms, unless the context clearly indicates otherwise. “Multiple” generally includes at least two, but does not exclude the inclusion of at least one.

[0072] It should be understood that the term "and / or" used in this article is merely a description of the relationship between related objects, indicating that three relationships can exist. For example, A and / or B can represent: A existing alone, A and B existing simultaneously, and B existing alone. Additionally, the character " / " in this article generally indicates that the preceding and following related objects have an "or" relationship.

[0073] It should also be noted that the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a product or system comprising a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a product or system. Without further limitation, an element defined by the phrase "comprising one..." does not exclude the presence of other identical elements in the product or system that includes said element.

[0074] Existing fluid equipment filters fluids by installing a filter screen inside the flow channel. After a long period of use, the filter screen needs to be cleaned or replaced. However, due to the narrow distance between the flow channel and other equipment or walls, traditional integrated filter screens require a large operating space and special tools during disassembly and assembly, making disassembly and assembly inconvenient and preventing maintenance personnel from quickly completing local cleaning or replacement of the filter screen.

[0075] This invention creatively provides a filter screen comprising multiple filter modules arranged sequentially, each filter module including a filter screen support and a filter screen body disposed on the filter screen support; adjacent filter screen supports can be connected by magnetic force to maintain the stability of the overall filter screen, and can also be quickly separated during maintenance by demagnetizing or applying external force; this allows the filter screen supports to be disassembled and installed separately in a confined space without disassembling the entire filter screen, thus improving the convenience of disassembling and installing the filter screen.

[0076] Example 1

[0077] <Filter 1>

[0078] like Figures 1a to 1b As shown, this embodiment provides a filter screen 1, including multiple filter modules arranged sequentially. Each filter module includes a filter support 11 and a filter body 12 disposed on the filter support 11. The multiple filter supports 11 are arranged sequentially and connected to form a filter screen. A magnetic structure is provided between the filter supports 11 of each two adjacent filter modules. The magnetic structure allows the two adjacent filter supports to be both connected and separated. That is, the two adjacent filter supports 11 can be connected together by magnetic force, and can be separated when the magnetic force disappears or when an external force is applied to the two adjacent filter supports 11. Specifically, the filter body 12 filters the flowing air, and the filter body 12 is a HEPA filter.

[0079] When two adjacent filter supports 11 are connected together, multiple filter supports 11 form a whole, ensuring the stability of the filter 1. When the magnetic force is removed or an external force is applied to the two adjacent filter supports 11, the two adjacent filter supports 11 can be separated from each other, making it easy to disassemble and assemble the filter supports 11 separately (the filter 1 can be disassembled and assembled by the left or right side along the length of the filter 1, or by both sides along the length of the filter 1), without having to disassemble and assemble the filter 1 as a whole. This allows the filter 1 to be disassembled and assembled in a confined space without the need for professional disassembly and assembly tools. The disassembly and assembly methods are flexible and the disassembly and assembly process is simple, reducing the difficulty of maintaining the filter 1. The filter 1 can be cleaned or replaced in a timely manner, ensuring the filtration effect of the filter 1.

[0080] Furthermore, such as Figures 2a to 2b As shown, the filter supports 11 of two adjacent filter modules include a first filter support 111 and a second filter support 112. A first magnet 41 is provided on the front side of the first filter support 111 near the second filter support 112, and a second magnet 42 is provided on the front side of the second filter support 112 near the first filter support 111. The first magnet 41 and the second magnet 42 have opposite magnetic properties. When the external force applied to the two adjacent filter supports 11 is greater than the magnetic force (magnetic attraction) between the first magnet 41 and the second magnet 42, the two adjacent filter supports 11 can be separated from each other.

[0081] Specifically, there are two first magnets 41, which are spaced apart in the width direction of the filter screen 1; there are two second magnets 42, which are spaced apart in the width direction of the filter screen 1; the two first magnets 41 and the two second magnets 42 are arranged in a one-to-one correspondence.

[0082] The first magnet 41 is detachably mounted on the first filter support 111, and the second magnet 42 is detachably mounted on the second filter support 112. The first magnet 41 and the second magnet 42 can be replaced as needed to make the first magnet 41 and the second magnet 42 have corresponding magnetic forces.

[0083] The magnetic force between two adjacent filter supports 11 at different positions is different. When the external force applied to the first and last ends of the entire filter support 11 is different, the two adjacent filter supports 11 at different positions will separate from each other, which improves the convenience of disassembling and assembling the filter 1 and adapts to different disassembly and assembly spaces.

[0084] Preferably, along the length of the filter screen 1, the magnetic forces between two adjacent filter screen supports 11 at different positions are arranged in a gradient order from large to small or from small to large.

[0085] The following further describes the connection structure between the first filter support 111 and the first magnet 41, and the connection structure between the second filter support 112 and the second magnet 42. The first filter support 111 and the first magnet 41 are detachably connected by a first snap-fit ​​structure, which facilitates timely disassembly or replacement of the first magnet 41; the second filter support 112 and the second magnet 42 are detachably connected by a second snap-fit ​​structure, which facilitates timely disassembly or replacement of the second magnet 42.

[0086] Specifically, both the first and second snap-fit ​​structures include a slot 13 and a plate 431; the first filter support 111 and the second filter support 112 are both provided with slots 13 on the side near the second filter support 112 and the second filter support 112 on the side near the first filter support 111; the first magnet 41 and the second magnet 42 both include a magnet body 44 and a magnet support 43, the magnet support 43 surrounds the outside of the magnet body 44, and the magnet support 43 forms the plate 431; the plate 431 and the slot 13 cooperate to set the first magnet 41 on the first filter support 111 and the second magnet 42 on the second filter support 112; the side wall of the slot 13 of the first filter support 111 and the corresponding plate 431 are connected by screws, and the side wall of the slot 13 of the second filter support 112 and the corresponding plate 431 are connected by screws.

[0087] The same first filter holder 111 can be adapted to first magnets 41 of different sizes, and the same second filter holder 112 can be adapted to second magnets 42 of different sizes.

[0088] <Filter Components>

[0089] like Figures 1a to 9As shown, this embodiment also provides a filter assembly, including a panel 2 and a filter 1 as described above; a plurality of filter supports 11 are arranged sequentially in a first direction, and a panel 2 is provided at the first end and the last end of the plurality of filter supports 11 as a whole; the panel 2 and the filter support 11 at the first end and the panel 2 and the filter support 11 at the last end are both connected to each other and separated from each other.

[0090] When the panel 2 at the first end and the filter support 11 are connected and the panel 2 at the last end and the filter support 11 are separated, the panel 2 at the first end and the entire filter 1 can be pulled along the positive direction 511 of the first direction; then the panel 2 at the first end and the entire filter 1 can be disassembled along the positive direction 511 of the first direction, and the panel 2 at the first end and the entire filter 1 can be installed along the negative direction 512 of the first direction.

[0091] When the panel 2 and filter support 11 at the first end are separated and the panel 2 and filter support 11 at the tail end are connected, the panel 2 and the entire filter 1 at the tail end can be pulled in the reverse direction 512 of the first direction; then the panel 2 and the entire filter 1 at the tail end can be disassembled in the reverse direction 512 of the first direction, and the panel 2 and the entire filter 1 at the tail end can be installed in the forward direction 511 of the first direction.

[0092] When the panel 2 and filter support 11 at the first end and the panel 2 and filter support 11 at the last end are connected, the panel 2 and part of the filter support 11 at the first end can be pulled along the positive direction 511 of the first direction, and the panel 2 and another part of the filter support 11 at the last end can be pulled along the negative direction 512 of the first direction; then the panel 2 and part of the filter support 11 at the first end can be disassembled along the positive direction 511 of the first direction and the panel 2 and another part of the filter support 11 at the last end can be installed, and the panel 2 and another part of the filter support 11 at the last end can be disassembled along the negative direction 512 of the first direction and the panel 2 and part of the filter support 11 at the first end can be installed.

[0093] Among them, the first end is the first end of the entire multiple filter screen brackets 11, and the last end is the last end of the entire multiple filter screen brackets 11.

[0094] In this way, depending on the actual disassembly and assembly space, the entire filter screen 1 or part of the filter screen bracket 11 can be disassembled or assembled along the forward direction 511 or the reverse direction 512 of the first direction, which improves the convenience of disassembling and assembling the filter screen 1.

[0095] like Figures 3a to 5bAs shown, the structure required for connecting the panel 2 and the filter support 11 is further explained. The filter assembly also includes a connector 3, which movably connects the panel 2 and the corresponding filter support 11. In the direction of movement of the connector 3, the connector 3 has a first working position and a second working position.

[0096] like Figure 3a and Figure 3c As shown, when connector 3 is in the first working position, panel 2 and the corresponding filter holder 11 are in a connected state; Figure 3b As shown, when the connector 3 is in the second working position, the panel 2 and the corresponding filter support 11 are in a separated state;

[0097] By switching the connector 3 between the first working position and the second working position, the panel 2 and the corresponding filter support 11 can be switched between a connected state and a separated state; that is, by placing the connector 3 in different positions, the panel 2 and the corresponding filter support 11 can be connected or separated.

[0098] In this way, the disassembly and assembly direction can be selected according to the actual disassembly and assembly space, so that the panel 2 and the corresponding filter screen bracket 11 are in a connected state, and then the entire filter screen 1 can be disassembled or the filter screen bracket 11 can be disassembled and assembled separately.

[0099] Furthermore, the connector 3 is provided with a first connecting part 31 and a second connecting part 32; in the panel 2 and the corresponding filter support 11, the first connecting part 31 and the panel 2 are movably connected by a first connecting structure, and the second connecting part 32 and the filter support 11 are movably connected by a second connecting structure.

[0100] When the connector 3 is in the first working position, the first connection structure and the second connection structure have limiting effects on the panel 2 and the corresponding filter support 11 in at least the first direction forward 511, the first direction reverse 512, the second direction forward 521, the second direction reverse 522, the third direction forward 531, and the third direction reverse 532; thus, the panel 2 and the corresponding filter support 11 can be stably and reliably connected.

[0101] Wherein, the first direction is the length direction of filter 1, the second direction is the width direction of filter 1, and the third direction is the thickness direction of filter 1.

[0102] The following further explains the connection structure required for connector 3, panel 2, and filter support 11. One of the first connection structure and the second connection structure is a sliding connection structure, and the other is a plug-in connection structure. The sliding direction of the sliding connection structure is parallel to the plug-in direction of the plug-in connection structure. Thus, by operating connector 3 to slide along the sliding direction of the sliding connection structure, the plug-in connection structure can be plugged in, which is simple and convenient.

[0103] Furthermore, the sliding connection structure includes a groove and a slider. The first connecting part 31 and the panel 2 are connected by the cooperation of the slider and the groove, which has a limiting effect on the panel 2 and the corresponding filter support 11 in at least a third-direction positive direction 531 and a third-direction negative direction 532.

[0104] The plug-in connection structure includes a pin 321 and a socket 141. The second connection part 32 and the filter support 11 are connected by the cooperation of the pin 321 and the socket 141, which has a limiting effect on the panel 2 and the corresponding filter support 11 in at least the first direction forward 511, the first direction reverse 512, the second direction forward 521 and the second direction reverse 522.

[0105] Thus, through the cooperative connection of the slider and the groove, and the cooperative connection of the pin 321 and the socket 141, the panel 2 and the corresponding filter support 11 are limited in at least six directions, thereby achieving a stable and reliable connection between the panel 2 and the corresponding filter support 11.

[0106] Specifically, a support groove 14 is formed at one end of the filter support 11 near the panel 2, and the support groove 14 extends along the second direction; an insertion hole 141 is formed on the side wall of the support groove 14 in the second direction; the connector 3 is disposed in the support groove 14 and can slide along the support groove 14; a second connecting part 32 is formed with a pin 321, and the extending direction of the pin 321 is parallel to the second direction; the pin 321 and the insertion hole 141 are interference fit.

[0107] By sliding the connector 3 along the second direction, the pin 321 and the socket 141 can be connected and disconnected;

[0108] The slide includes a panel slide 231 and a connector slide 311, and the extension directions of both the panel slide 231 and the connector slide 311 are parallel to the second direction; the slider includes a panel slider 232 and a connector slider 312.

[0109] A panel groove 23 is formed at one end of the panel 2 near the filter support 11; a panel slide groove 231 and a panel slider 232 are formed on the side wall of the panel groove 23 near the filter support 11, and the panel slider 232 is away from the panel groove 23; a connector slide groove 311 and a connector slider 312 are formed in the first connecting part 31.

[0110] The connector slider 312 and the panel slide groove 231 cooperate, and the panel slider 232 and the connector slide groove 311 cooperate, so that the connector 3 slides along the second direction, which has a limiting effect on the panel 2 and the corresponding filter support 11 in the third direction positive 531 and the third direction negative 532.

[0111] In addition, the first connecting part 31 has a connecting part mounting groove 313 formed at one end of the connecting part slide groove 311, and the connecting part mounting groove 313 and the connecting part slide groove 311 are connected.

[0112] A panel limiting block 233 is formed at the end of the panel slider 232. When the panel limiting block 233 and the side wall of the panel groove 23 near the filter support 11 are engaged with the first connecting part 31, they have a limiting effect on the panel 2 and the corresponding filter support 11 in the first direction forward 511 and the first direction reverse 512. In this way, the connecting member 3 can slide stably relative to the panel 2 and the corresponding filter support 11, thereby realizing a stable connection between the panel 2 and the corresponding filter support 11.

[0113] When installing the connector 3 and panel 2, and the corresponding filter bracket 11, by aligning the panel limiting block 233 with the connector mounting groove 313 and allowing the panel limiting block 233 to pass through the connector mounting groove 313, the connector slider 312 and the panel slide groove 231 can slide together, and the panel slider 232 and the connector slide groove 311 can slide together.

[0114] Specifically, the connector mounting groove 313 and the connector sliding groove 311 form an L-shaped structure, and the panel limiting block 233 and the panel slider 232 form an L-shaped structure; along the reverse direction 532 of the third direction, the connector sliding groove 311 and the connector mounting groove 313 are arranged in sequence, and the panel slider 232 and the panel limiting block 233 are arranged in sequence.

[0115] In this embodiment, each panel 2 and the corresponding filter support 11 are connected by two connectors 3, which are spaced apart and movable in the second direction.

[0116] like Figure 4a and Figure 4b As shown, by moving the two connectors 3 away from each other, both connectors 3 can be in the first working position, and thus the panel 2 and the corresponding filter support 11 are in a connected state.

[0117] like Figure 5a and Figure 5b As shown, by bringing the two connectors 3 close to each other, both connectors 3 can be in the second working position, thereby separating the panel 2 and the corresponding filter support 11.

[0118] Specifically, the connector 3 is slidably disposed relative to the panel 2 and the corresponding filter support 11; when the two connectors 3 are operated in the second direction and moved away from each other, the panel 2 and the corresponding filter support 11 can be in a connected state; when the two connectors 3 are operated in the second direction and moved closer to each other, the panel 2 and the corresponding filter support 11 can be in a separated state.

[0119] Ventilation equipment

[0120] This embodiment also provides a ventilation device, including a housing 61 and a filter assembly as described above; the housing 61 has an internal mounting groove, and the side wall of the housing 61 has a first opening 621 and a second opening 622 that are disposed opposite to each other, and both the first opening 621 and the second opening 622 are in communication with the mounting groove.

[0121] Panel 2 includes a first panel 21 and a second panel 22. The first panel 21 is slidably disposed at the first opening 621, and the second panel 22 is slidably disposed at the second opening 622. The filter screen 1 is disposed in the mounting groove and located between the first panel 21 and the second panel 22.

[0122] When the first panel 21 and the corresponding filter support 11 are connected and the second panel 22 and the corresponding filter support 11 are separated, the first panel 21 and the entire filter 1 can be pulled out through the first opening 621.

[0123] When the first panel 21 and the corresponding filter support 11 are in a separated state and the second panel 22 and the corresponding filter support 11 are in a connected state, the second panel 22 and the entire filter 1 can be pulled out through the second opening 622.

[0124] When the first panel 21 and the corresponding filter support 11 and the second panel 22 and the corresponding filter support 11 are connected, the first panel 21 and a portion of the filter 1 can be pulled out through the first opening 621, and the second panel 22 and another portion of the filter 1 can be pulled out through the second opening 622.

[0125] Taking a wall-mounted vertical ventilation system as an example, the disassembly and assembly process of the filter 1 is further explained; the first opening 621 and the second opening 622 are arranged opposite each other in the horizontal direction. The filter 1 includes two filter supports 11, which are the first filter support 111 and the second filter support 112, respectively; the first panel 21 and the first filter support 111 are arranged correspondingly, and the second panel 22 and the second filter support 112 are arranged correspondingly. The first filter support 111 and the second filter support 112 are connected by the magnetic force between the first magnet 41 and the second magnet 42; the positive direction 511 of the first direction is left, the negative direction 512 of the first direction is right, the positive direction 521 of the second direction is up, the negative direction 522 of the second direction is down, the positive direction 531 of the third direction is forward, and the negative direction 532 of the third direction is backward;

[0126] The vertical ventilation equipment can be installed in the following ways: the entire vertical ventilation equipment is placed close to the corner of the wall 71; the left side of the vertical ventilation equipment is placed close to the left wall 72; and the right side of the vertical ventilation equipment is placed close to the right wall 73. The filter screen 1 can be installed and removed in the following ways: both sides can be installed and removed at the same time; only the right side can be installed and removed; and only the left side can be installed and removed.

[0127] like Figure 10a and Figure 10b As shown, when the vertical ventilation equipment is installed close to the corner 71, the space on the left side and left wall 72 of the casing 61 and the right side and right wall 73 of the casing 61 is very small. Therefore, the filter screen 1 is removed and installed from the left side and right side of the casing 61 respectively.

[0128] Specifically, in the two connecting pieces 3 corresponding to the first panel 21 and the first filter support 111, the upper connecting piece 3 is slid upward and the lower connecting piece 3 is slid downward, so that both connecting pieces 3 are in the first working position, and the first panel 21 and the first filter support 111 are in a connected state; in the two connecting pieces 3 corresponding to the second panel 22 and the second filter support 112, the upper connecting piece 3 is slid upward and the lower connecting piece 3 is slid downward, so that both connecting pieces 3 are in the first working position, and the second panel 22 and the second filter support 112 are in a connected state.

[0129] When disassembling filter 1, pull the first panel 21 to the left and the second panel 22 to the right; when the external force applied to the first panel 21 and the second panel 22 is greater than the magnetic force (magnetic attraction) between the first filter support 111 and the second filter support 112, the first filter support 111 and the second filter support 112 separate from each other. Then, the first panel 21 and the first filter support 111 can be pulled out from the first opening 621, and the second panel 22 and the second filter support 112 can be pulled out from the second opening 622 (e.g., ...). Figure 7a and Figure 7b (as shown), thus the filter body 12 on the first filter support 111 and the filter body 12 on the second filter support 112 can be cleaned or replaced;

[0130] During installation, insert the first filter holder 111 and the first panel 21 sequentially into the first opening 621, and push the first panel 21 to the right to insert the first filter holder 111 into the mounting groove; insert the second filter holder 112 and the second panel 22 sequentially into the second opening 622, and push the second panel 22 to the left to insert the second filter holder 112 into the mounting groove; the first filter holder 111 and the second filter holder 112 are connected by the magnetic force between the first magnet 41 and the second magnet 42, thus the first panel 21, the first filter holder 111, the second filter holder 112, and the second panel 22 are sequentially connected (e.g., ...). Figure 6a and Figure 6b As shown), the filter screen 1 is then installed in the mounting slot; this solves the problem that when the existing vertical ventilation equipment is set close to the corner 71, the space on the left side and left wall 72 of the housing 61 and the right side and right wall 73 of the housing 61 is very small, making it impossible to remove and install the entire filter screen 1 from the left and right sides of the housing 61.

[0131] like Figure 10a and Figure 10bAs shown, when the left side of the vertical ventilation equipment is set close to the left wall 72, the space between the left side of the housing 61 and the left wall 72 is small, while the space between the right side of the housing 61 and the right wall 73 is large. Therefore, the filter screen 1 can be removed and installed from the right side of the housing 61.

[0132] Specifically, when disassembling the filter screen 1, in the two connecting pieces 3 corresponding to the first panel 21 and the first filter screen bracket 111, the upper connecting piece 3 slides downward and the lower connecting piece 3 slides upward, so that both connecting pieces 3 are in the second working position, and the first panel 21 and the first filter screen bracket 111 are in a separated state; in the two connecting pieces 3 corresponding to the second panel 22 and the second filter screen bracket 112, the upper connecting piece 3 slides upward and the lower connecting piece 3 slides downward, so that both connecting pieces 3 are in the first working position, and the second panel 22 and the second filter screen bracket 112 are in a connected state; pulling the second panel 22 to the right, the second panel 22, the second filter screen bracket 112 and the first filter screen bracket 111 can be sequentially pulled out from the second opening 622 (the external force applied to the second panel 22 is less than the magnetic force between the first filter screen bracket 111 and the second filter screen bracket 112, so the first filter screen bracket 111 and the second filter screen bracket 112 are still connected together, such as Figure 8 (as shown), thus the filter body 12 on the first filter support 111 and the filter body 12 on the second filter support 112 can be cleaned or replaced;

[0133] During installation, the first filter support 111, the second filter support 112, and the second panel 22 are sequentially inserted into the second opening 622. Among the first filter support 111, the first panel 21, and the corresponding connector 3, the panel limiting block 233 of the first panel 21 aligns with the connector mounting groove 313, and the panel limiting block 233 of the first panel 21 passes through the connector mounting groove 313. This causes the upper connector 3 to slide upwards and the lower connector 3 to slide downwards, thus placing both connectors 3 in the first working position. The first panel 21 and the first filter support 111 are then connected. In this way, the first panel 21, the first filter support 111, the second filter support 112, and the second panel 22 are sequentially connected (e.g., ...). Figure 6a and Figure 6b As shown), the filter screen 1 is then installed in the mounting slot, which solves the problem that when the left side of the existing vertical ventilation equipment is set close to the left wall 72, the space on the left side of the housing 61 and the left wall 72 is small, making it impossible to remove and install the entire filter screen 1 from the left side of the housing 61.

[0134] When the right side of the vertical ventilation equipment is close to the right wall 73, the space between the right side of the housing 61 and the right wall 73 is small, while the space between the left side of the housing 61 and the left wall 72 is large. Therefore, the filter screen 1 can be removed and installed from the left side of the housing 61.

[0135] Specifically, when disassembling the filter screen 1, in the two connecting pieces 3 corresponding to the second panel 22 and the second filter screen bracket 112, the upper connecting piece 3 slides downward and the lower connecting piece 3 slides upward, so that both connecting pieces 3 are in the second working position, and the second panel 22 and the second filter screen bracket 112 are in a separated state; in the two connecting pieces 3 corresponding to the first panel 21 and the first filter screen bracket 111, the upper connecting piece 3 slides upward and the lower connecting piece 3 slides downward, so that both connecting pieces 3 are in the first working position, and the first panel 21 and the first filter screen bracket 111 are in a connected state; pulling the first panel 21 to the left, the first panel 21, the first filter screen bracket 111 and the second filter screen bracket 112 can be sequentially pulled out from the first opening 621 (the external force applied to the first panel 21 is less than the magnetic force between the first filter screen bracket 111 and the second filter screen bracket 112, so the first filter screen bracket 111 and the second filter screen bracket 112 are still connected together, such as Figure 9 (as shown), thus the filter body 12 on the first filter support 111 and the filter body 12 on the second filter support 112 can be cleaned or replaced;

[0136] During installation, the second filter support 112, the first filter support 111, and the first panel 21 are sequentially inserted into the first opening 621. In the second filter support 112, the second panel 22, and the corresponding connector 3, the panel limiting block 233 of the second panel 22 aligns with the connector mounting groove 313, and the panel limiting block 233 of the second panel 22 passes through the connector mounting groove 313. This causes the upper connector 3 to slide upwards and the lower connector 3 to slide downwards, thus placing both connectors 3 in the first working position. The second panel 22 and the second filter support 112 are then connected. In this way, the first panel 21, the first filter support 111, the second filter support 112, and the second panel 22 are sequentially connected (e.g., ...). Figure 6a and Figure 6b As shown), the filter screen 1 is then installed in the mounting slot, which solves the problem that when the right side of the existing vertical ventilation equipment is set close to the right wall 73, the space between the right side of the housing 61 and the right wall 73 is small, making it impossible to remove and install the entire filter screen 1 from the right side of the housing 61.

[0137] In summary, this embodiment, by designing two adjacent filter supports 11 to be connected by magnetic force, allows for the selection of the corresponding filter 1 disassembly and assembly method according to the setting method of the ventilation equipment. The disassembly and assembly method is flexible and the disassembly and assembly process is simple, reducing the difficulty of maintaining the filter 1. The filter 1 can be cleaned or replaced in a timely manner, meeting the different needs of disassembling and assembling the filter 1 under different setting methods of the ventilation equipment, and avoiding the problem of being unable to disassemble and assemble the filter 1 due to the limitation of disassembly and assembly space and the problem of not being able to disassemble and assemble the filter 1 when the length of the filter 1 is large.

[0138] Preferably, the ventilation equipment is a cabinet-type air conditioner indoor unit 6; a fresh air duct is formed at the bottom of the casing 61, and a fresh air inlet is formed on the rear side wall of the casing 61. The fresh air inlet and the fresh air duct are connected, and the fresh air inlet and the outside are connected through a fresh air duct. Outdoor fresh air can enter the fresh air duct through the fresh air duct and the fresh air inlet; an installation groove is formed on the side wall of the casing 61 of the fresh air duct, and a filter screen 1 is installed in the installation groove; when outdoor fresh air flows through the filter screen 1, the filter screen 1 filters the outdoor fresh air.

[0139] Example 2

[0140] Unlike Embodiment 1, in two adjacent filter supports 11, the position of the first magnet 41 on the first filter support 111 is adjustable, and the position of the second magnet 42 on the second filter support 112 is adjustable. The position of the first magnet 41 on the first filter support 111 and the position of the second magnet 42 on the second filter support 112 can be adjusted according to installation requirements, so that the relative position of the first filter support 111 and the second filter support 112 can be adapted to different installation spaces, thus expanding the applicability of the filter 1.

[0141] Alternatively, the first magnet 41 may have multiple different first connection positions, and the second magnet 42 may have multiple different second connection positions; depending on the installation requirements, the corresponding first connection positions and second connection positions may be connected, so that the relative positions of the first filter support 111 and the second filter support 112 can be adapted to different installation spaces, thereby expanding the applicability of the filter 1.

[0142] Alternatively, the first magnet 41 is rotatably mounted on the first filter screen support 111 via a first rotating shaft, and the second magnet 42 is rotatably mounted on the second filter screen via a second rotating shaft. When the first filter screen support 111 and the second filter screen support 112 are connected by the magnetic force between the first magnet 41 and the second magnet 42, the first filter screen support 111 and the second filter screen support 112 can rotate relative to each other. On the one hand, the relative tilt angle between the main body surface of the first filter screen support 111 and the main body surface of the second filter screen support 112 can be adjusted according to installation requirements so that the filter screen 1 can adapt to different installation spaces and expand the application range of the filter screen 1. On the other hand, the multiple filter screen supports 11 of the filter screen 1 can be folded up for easy storage.
