[0016] The limiting frame includes a first sidewall, a second sidewall, and a third sidewall. The first sidewall and the third sidewall are arranged side-by-side along a direction perpendicular to the filter surface and are respectively connected to the second sidewall. The first sidewall, the second sidewall, and the third sidewall enclose the guide groove, and the third sidewall is in contact with the supporting base frame; or

[0017] The limiting frame includes a first sidewall and a second sidewall. The second sidewall is connected to the first sidewall at an angle, and the first sidewall and the second sidewall together form the guide groove. In the direction perpendicular to the filter surface, the surface of one side of the guide portion contacts the first sidewall, and the surface of the other side contacts the supporting bottom frame.

The second sidewall is mounted on the second mounting member. A portion of the second mounting member is located on the outside of the filter and another portion is mounted on the supporting bottom frame.

[0022] In some embodiments, the limiting frame includes a third mounting member, which is integrally disposed on the portion of the limiting frame that is mounted on the supporting bottom frame, and the third mounting member is used to be mounted on the body of the air handling equipment.

[0031] Based on the filter assembly and air handling equipment of this application embodiment, multiple limiting frames restrict the position of the filter element. These limiting frames not only provide support for the filter element but also allow the filter element to be removed from the side of the filter assembly by releasing the fixing of at least one of the limiting frames. This reduces the number of structural components that need to be moved and minimizes the size of the installation opening for the filter element, resulting in less operating space required. Therefore, even when the filter assembly is in a relatively confined space, the filter element can be easily removed. In addition to limiting the position of the filter element, the multiple limiting frames also guide the movement of the filter element during its entry and exit from the installation opening, providing support and allowing the filter element to smoothly enter the area enclosed by the multiple limiting frames mounted on the support base frame. This guides the smooth movement of the filter element and effectively improves the efficiency of filter element assembly and disassembly. Attached Figure Description

[0046] To make the objectives, technical solutions, and advantages of this application clearer, the following detailed description is provided in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the scope of this application.

[0047] Filter assemblies are used to filter dust, particulate matter, and other impurities from the air. During use, they need to be cleaned to maintain their filtering effect. Filter assemblies in related technologies are typically fixed in place and inconvenient to disassemble and clean, especially when installation space is limited. Users find it difficult to easily remove the filter for cleaning or replacement, affecting equipment maintenance efficiency. Therefore, this application provides a filter assembly and air handling equipment, improving the structure of the filter assembly to facilitate disassembly and assembly.

[0048] like Figure 1 The diagram shown is a structural schematic of a filter assembly 10 according to an embodiment of this application. The filter assembly 10 is used in an air handling device, such as... Figure 2 As shown, the filter assembly 10 includes a supporting base frame 100, multiple limiting frames 200, and filter elements 300.

[0049] Multiple limiting frames 200 are detachably mounted on the supporting base frame 100, and the filter element 300 is disposed on the limiting frames 200. The filter assembly 10 has an installed state and a disassembled state, such as... Figure 1The diagram shown is a schematic representation of the filter assembly 10 in an installed state according to an embodiment of this application. In the installed state, multiple limiting frames 200 are installed on the supporting base frame 100, and the multiple limiting frames 200 enclose a receiving space for accommodating the filter element 300. Figure 3 The diagram shown is a schematic representation of a filter assembly 10 in a disassembled state according to an embodiment of this application. In this disassembled state, at least one limiting frame 200 is movable relative to the supporting base frame 100, so that the remaining limiting frames 200 mounted on the supporting base frame 100 define an installation opening 102 for the filter element 300 to enter and exit. The filter element 300 can move in and out of the installation opening 102 along a preset direction, which is an angled direction to the thickness direction of the filter element 300. For example, the preset direction can be the length direction of the filter element 300 or the width direction of the filter element 300.

[0050] In the installation state of the filter assembly 10 of this application embodiment, at least one of the supporting bottom frame 100 and the plurality of limiting frames 200 of the filter assembly 10 can be installed on the body of the air handling equipment to fix the position of the filter assembly 10 relative to the body of the air handling equipment. The filter element 300 is used to filter dust, particulate matter and other impurities in the air.

[0051] In the installed state of the filter assembly 10, the filter element 300 can be stably installed on the supporting base frame 100 by the limiting frame 200 and the support of the supporting base frame 100, so as to achieve a good filtration effect. At the same time, the multiple limiting frames 200 are only used to limit the position of the filter element 300, and do not lock the filter element 300. Therefore, in the disassembled state of the filter assembly, when one of the limiting frames 200 is movable relative to the supporting base frame 100, the movable supporting base frame 100 can be moved so that at least a portion of the remaining limiting frames 200 can surround and form the installation opening 10. 2. When the filter element 300 needs to be cleaned or repaired, the action is applied to the part of the filter element 300 exposed at the installation opening 102. The filter element 300 can be pulled out for cleaning and repair. When it is necessary to install the filter element 300 on multiple limiting frames 200, the action is applied to the filter element 300 through the installation opening 102, so that the filter element 300 enters the area enclosed by the multiple limiting frames 200 installed on the support base frame 100. Then, the movable limiting frame 200 is covered with the installation opening 102 and fixedly installed on the support base frame 100, so that the filter assembly 10 can be restored to the installation state.

[0052] The filter assembly 10 of this application embodiment restricts the position of the filter element 300 by setting multiple limiting frames 200. The multiple limiting frames 200 can not only provide support for the filter element 300, but also allow the filter element 300 to be removed from the side of the filter assembly 10 after releasing the fixation of at least one of the limiting frames 200. The number of structural parts that need to be moved is small, and the size of the installation opening 102 for the filter element 300 to enter and exit is also small, which makes the required operating space small. Therefore, even when the filter assembly 10 is in a relatively narrow space, the filter element 300 can be easily removed. In addition to limiting the filter element 300, the multiple limiting frames 200 can also guide the movement of the filter element 300 during the process of the filter element 300 entering and exiting the installation opening 102, and provide support for the filter element 300. This allows the filter element 300 to smoothly enter the area enclosed by the multiple limiting frames 200 installed on the support base frame 100, and guides the filter element 300 to move smoothly, thereby effectively improving the installation and removal efficiency of the filter element 300.

[0053] In this embodiment, when the filter assembly is installed, multiple limiting frames 200 are disposed on the outer periphery of the filter element 300 to enclose and form an accommodating space for the filter element 300. The multiple limiting frames 200 limit the filter element 300 from multiple directions. At the same time, it is also convenient to disassemble the corresponding limiting frames 200 according to the movement direction requirements of the filter element 300 to form the corresponding installation opening 102, so that the filter element 300 can move in the required direction to pass through the corresponding installation opening 102. This can meet the installation requirements in various scenarios. Therefore, when the filter assembly is installed in the air handling equipment, the air handling equipment can adapt to various installation scenarios and is not limited by space.

[0054] In some embodiments, the limiting frame 200 has a guide groove 200a. In the installed state, the portions of the multiple limiting frames 200 with guide grooves 200a enclose each other to form a receiving space and define the position of the filter element 300. In the disassembled state, the guide groove 200a guides the filter element 300 in and out of the mounting opening 102. During the movement of the filter element 300 relative to the limiting frame 200, the wall surface of the guide groove 200a contacts the surface of the filter element 300, which can better perform the guiding function and guide the filter element 300 to move smoothly. At the same time, it can also better perform the supporting function and prevent the filter element 300 from deforming and affecting the filtration effect.

[0055] In some other embodiments, the filter element 300 has a guide groove 200a. In the installed state of the filter assembly 10, a plurality of limiting frames 200 surround and form a receiving space for accommodating the filter element 300, and a portion of the limiting frames 200 is disposed within the guide groove 200a to limit the position of the filter element 300. In the disassembled state of the filter assembly 10, the guide groove 200a guides the filter element 300 in and out of the mounting opening 102.

[0056] like Figure 2 As shown, the filter element 300 includes a filter frame 310 and a filter screen 320 disposed on the filter frame 310. The filter screen 320 has a filter surface; the larger the area of ​​the filter surface, the larger the effective filtration area of ​​the filter screen 320. Optionally, a portion of the filter frame 310 forms a guide portion, and the limiting frame 200 has a guide groove 200a. The guide portion is embedded in the guide groove 200a, which facilitates full utilization of space, reserving more space for installing the filter screen 320, and helps to increase the area of ​​the filter surface of the filter screen 320, thereby improving filtration efficiency.

[0057] When a portion of the filter frame 310 forms a guide portion, and the limiting frame 200 has a guide groove 200a, in some embodiments, such as Figure 4 As shown, the limiting frame 200 includes a first sidewall 210, a second sidewall 220, and a third sidewall 230. The first sidewall 210 and the third sidewall 230 are arranged side by side in a direction perpendicular to the filter surface, and the first sidewall 210 and the third sidewall 230 are respectively connected to the second sidewall 220. The first sidewall 210, the second sidewall 220, and the third sidewall 230 enclose a guide groove 200a, and the third sidewall 230 is in contact with the support base frame 100. When the guide part of the filter frame 310 is provided in the guide groove 200a, the filter frame 310 and the support base frame 100 are spaced apart. At this time, during the movement of the filter element 300 relative to the support base frame 100, the walls of the first sidewall 210, the second sidewall 220, and the third sidewall 230 respectively contact the surface of the guide part to guide the guide part to move smoothly.

[0058] When a portion of the filter frame 310 forms a guide portion and the limiting frame 200 has a guide groove 200a, in some embodiments, the limiting frame 200 includes a first sidewall 210 and a second sidewall 220, with the second sidewall 220 connected to the first sidewall 210 at an included angle. The first sidewall 210 and the second sidewall 220 together form the guide groove 200a. In a direction perpendicular to the filter surface, one side of the guide portion's surface contacts the first sidewall 210, and the other side's surface contacts the supporting base frame 100. At this time, during the movement of the filter element 300 relative to the supporting base frame 100, the surfaces of the first sidewall 210, the second sidewall 220, and the supporting base frame 100 respectively contact the surface of the guide portion to guide its smooth movement.

[0059] In some embodiments, the second sidewall 220 is mounted on the support base frame 100. That is, when the limiting frame 200 includes the first sidewall 210 and the second sidewall 220, or when the limiting frame 200 includes the first sidewall 210, the second sidewall 220 and the third sidewall 230, the first sidewall 210, the third sidewall 230 and the filter frame 310 are all located on the same side of the support base frame 100 in the direction perpendicular to the filter surface, and these sidewalls are integrally connected to the portion of the second sidewall 220 located outside the filter element 300. At the same time, the second sidewall 220 also extends to the periphery of the support base frame 100 to be mounted on the support base frame 100. At this time, when the limiting frame 200 includes a first sidewall 210 and a second sidewall 220, the portion of the first sidewall 210 and the second sidewall 220 not installed on the supporting base frame 100 encloses and forms a guide groove 200a. Alternatively, when the limiting frame 200 includes a first sidewall 210, a second sidewall 220, and a third sidewall 230, the portion of the first sidewall 210, the third sidewall 230, and the second sidewall 220 not installed on the supporting base frame 100 encloses and forms a guide groove 200a. Furthermore, in the installed state of the filter assembly 10, the portions of the multiple limiting frames 200 forming the guide groove 200a together enclose and form a receiving space for accommodating the filter element 300. Optionally, the second sidewall 220 is flat.

[0060] In some embodiments, such as Figure 5 As shown, the limiting frame 200 includes a first mounting member 201 and a second mounting member 202. The first mounting member 201 is mounted on the second mounting member 202, and the second mounting member 202 is mounted on the supporting base frame 100. Specifically, the first mounting member 201 is formed by an integrally formed first sidewall 210, second sidewall 220, and third sidewall 230; or, the first mounting member 201 is formed by an integrally formed first sidewall 210 and second sidewall 220. In this case, in the direction perpendicular to the filter surface, the first mounting member 201 of the filter element 300 and the multiple limiting frames 200 are located on the same side of the limiting frame 200, the second sidewall 220 is mounted on the portion of the second mounting member 202 located outside the filter element 300, and the other portion of the second mounting member 202 is located outside the supporting base frame 100 and mounted on the supporting base frame 100. Optionally, the second mounting member 202 is flat.

[0061] In this embodiment, the limiting frame 200 can be installed on the supporting base frame 100 by at least one of the following fixing methods: snap-fit ​​or screw fastening, so that the limiting frame 200 can be installed on the supporting base frame 100 or separated from the supporting base frame 100. Alternatively, the limiting frame 200 can be rotatably installed on the supporting base frame 100 in a direction parallel to the surface of the filter screen 320, so that after the fixed connection between the limiting frame 200 and the supporting base frame 100 is released, the limiting frame 200 can be rotated to expose the filter element 300 to the mounting opening 102. Simultaneously, the movable limiting frame 200 remains connected to the supporting base frame 100, preventing the movable limiting frame 200 from moving freely and easily being lost. When the second sidewall 220 is installed on the support base frame 100, the second sidewall 220 can be installed on the support base frame 100 by at least one of the following methods: snap-fit, screw fastening, and rotational installation; when the second mounting member 202 is installed on the support base frame 100, the second mounting member 202 can be installed on the support base frame 100 by at least one of the following methods: snap-fit, screw fastening, and rotational installation.

[0062] In this embodiment of the application, at least one of the limiting frame 200 and the supporting base frame 100 can be installed on the body of the air handling equipment. For example... Figure 4 and Figure 5 As shown, the limiting frame 200 also includes a third mounting component 203, which is mounted on the body of the air handling equipment.

[0063] In some embodiments, the third mounting member 203 is integrally disposed on the portion of the limiting frame 200 that is mounted on the supporting base frame 100. That is, when the second sidewall 220 is mounted on the supporting base frame 100, the third mounting member 203 is integrally disposed with the second sidewall 220; when the second mounting member 202 is mounted on the supporting base frame 100, the third mounting member 203 is integrally disposed with the second mounting member 202. Specifically, in a direction parallel to the filter surface, the third mounting member 203 extends away from the filter screen 320 to increase the size of the third mounting member 203, giving it a suitable contact area to contact the air handling unit's body and increasing installation stability. Simultaneously, during the installation of the filter assembly 10 on the air handling unit's body, the third mounting member 203 prevents interference with other structural components of the air handling unit's body, facilitating smooth installation of the filter assembly 10 on the air handling unit's body, or facilitating smooth removal of the filter assembly 10 from the air handling unit's body.

[0064] like Figure 6As shown, the filter assembly 10 includes an upper frame 21, a left frame 22, a lower frame 23, and a right frame 24 connected end-to-end. In the installed state of the filter assembly 10, the upper frame 21, left frame 22, lower frame 23, and right frame 24 surround the filter element 300 to collectively form a receiving space for accommodating the filter element 300. In some embodiments, a portion of the limiting frame 200 is formed by one of the upper frame 21, left frame 22, lower frame 23, and right frame 24, and / or, a portion of the limiting frame 200 is formed by multiple adjacent portions of the upper frame 21, left frame 22, lower frame 23, and right frame 24. Exemplarily, the filter assembly 10 includes four limiting frames 200, with the upper frame 21, left frame 22, lower frame 23, and right frame 24 each forming a limiting frame 200. For example, the upper border 21 and its adjacent left border 22 are integrally formed to form one of the limiting borders 200, and the lower border 23 and its adjacent right border 24 are integrally formed to form another limiting border 200. For example, the upper border 21 and the left border 22 each form a limiting border 200, and the lower border 23 and its adjacent right border 24 are integrally formed to form a limiting border 200.

[0065] When the same limiting frame 200 is formed by multiple integrally disposed components of the upper frame 21, left frame 22, lower frame 23, and right frame 24, after the limiting frame 200 is disassembled so that it can move relative to the supporting base frame 100, the filter element 300 can enter and exit the mounting opening 102 from multiple directions. For example, when the upper frame 21 and left frame 22 each form a limiting frame 200, and the lower frame 23 and its adjacent right frame 24 are integrally disposed and together form a limiting frame 200, the filter element 300 can enter and exit the mounting opening 102 from multiple directions. After the limiting frame 200, which is integrally formed by the frame 24, is removed, the filter element 300 can enter and exit the installation opening 102 through the area corresponding to the lower frame 23. The filter element 300 can also enter and exit the installation opening 102 through the area corresponding to the right frame 24. Alternatively, the filter element 300 can also enter and exit the installation opening 102 through the area corresponding to the junction of the right frame 24 and the lower frame 23, thus providing multiple directions for the filter element 300 to enter and exit the installation opening 102, making disassembly and assembly more flexible.

[0066] Considering the need for large-area filtration in the filter assembly 10 of this embodiment, the filter element 300 is relatively large. When the filter element 300 enters and exits the installation opening 102, its position through the opening results in a large overall size for the filter element 300 and its supporting frame 100, which is easily limited by space. Therefore, in this embodiment, the size of the filter element 300 is adjustable. This allows for a reduction in the size of the filter element 300 when it enters and exits the installation opening 102, thus reducing the space constraints on the filter assembly 10. Furthermore, the multiple limiting frames 200, in addition to limiting the position of the filter element 300, also guide its movement when its size is adjustable, providing support and facilitating smooth movement. This effectively improves the efficiency of assembly and disassembly of the filter element 300.

[0067] In this embodiment, the filter element 300 is configured to be size-adjustable, allowing it to be selected at different sizes to accommodate various sized spaces, thus filling the space completely. For example, when the space is large, the filter element 300 can be positioned at a relatively large size; when the space is small, it can be positioned at a relatively small size. It should be noted that the size-adjustable configuration of the filter element 300 includes both length and width adjustment. When comparing the dimensions of the filter element 300, the dimensions are determined by comparing the same direction of the filter element 300.

[0068] In some embodiments, the filter element 300 has a first state and a second state. The filter element 300 is configured to be size-adjustable to switch between the first state and the second state, and the size of the filter element 300 in the second state is smaller than the size of the filter element 300 in the first state. The first state of the filter element 300 is the state in which the filter element 300 is at its largest size when it is in the receiving space. That is, in the first state, the size of the filter element 300 can be at its maximum, or, to adapt to the size of the receiving space, the size of the filter element 300 is not necessarily at its maximum, as long as the filter element 300 can fill the receiving space. The size of the filter element 300 in the first state is determined by the size of the receiving space. The second state of the filter element 300 is any state in which the size of the filter element 300 is smaller than the size of the filter element 300 in the first state. That is, in the second state, the filter element 300 can have multiple sizes.

[0069] The filter element 300 is sized adjustable, which not only adapts to the size of the accommodating space but also allows for switching between a first and a second state, facilitating its removal from the side of the filter assembly 10. Optionally, in the installed state of the filter assembly 10, the filter element 300 is in the accommodating space in the first state; in the disassembled state of the filter assembly 10, the filter element 300 passes through the mounting opening 102 in the second state. The small size of the filter element 300 prevents it from occupying too much space when it protrudes from the mounting opening 102, thus allowing the filter assembly 10 to be installed in confined spaces and facilitating operation. Furthermore, the adjustable size of the filter element 300 allows for real-time shortening of its dimensions, facilitating smooth removal and preventing collisions with external structural components.

[0070] In some embodiments, the filter element 300 is configured to be foldable to achieve size adjustment. In the disassembled state, a portion of the filter element 300 passes through the mounting opening 102, and the portion of the filter element 300 outside the mounting opening 102 is folded relative to the portion of the filter element 300 located in the mounting opening 102, thereby shortening the size of the filter element 300. The filter element 300 includes a filter frame 310 and a filter screen 320. The filter screen 320 is mounted on the filter frame 310, which provides support for the filter screen 320, allowing the filter screen 320 to be in an extended or folded state.

[0071] Optionally, the filter element 300 includes at least two filter frames 310 and at least two filter screens 320. Each filter screen 320 is mounted on a filter frame 310, and the filter frame 310 and the filter screen 320 mounted thereon together form a filter unit 31. That is, the filter element 300 includes multiple filter units 31, such as 2, 3, or 5. The filter frames 310 of two adjacent filter units 31 are rotatably connected to achieve foldability of the filter element 300. For example, the filter element 300 enters and exits the mounting opening 102 in a preset direction. Correspondingly, the filter element 300 is configured as multiple foldable filter units 31, such as... Figure 7 As shown, when the filter element 300 needs to be installed on the limiting frame 200, one of the filter units 31 of the filter element 300 is inserted into the limiting frame 200 through the installation opening 102 along a preset direction. Then, the next filter unit 31 of the filter element 300 is unfolded so that two adjacent filter units 31 are arranged side by side along a preset direction. Then, the next filter unit 31 is inserted through the installation opening 102 along a preset direction. In this way, multiple filter units 31 of the filter element 300 are sequentially inserted into the limiting frame 200. Figure 8As shown, when it is necessary to remove the filter element 300 from the limiting frame 200, after one of the filter units 31 passes through the mounting opening 102, the filter unit 31 can be folded relative to the filter unit 31 provided in the mounting opening 102 to achieve the purpose of reducing the size, and then the next filter unit 31 can be taken out from the mounting opening 102.

[0072] Optionally, the filter element 300 includes at least two filter frames 310 and a filter screen 320. The at least two filter frames 310 are arranged around and connected to the filter screen 320, and adjacent filter frames 310 are rotatably connected to allow the filter element 300 to be folded at least once, for example, folded once, twice, or four times. With this structure, the filter screen 320 can have a larger filtration area to achieve a better filtration effect.

[0073] In this embodiment, the method of rotating the two adjacent filter frames 310 is not limited. Any method that can achieve the rotating connection of the two adjacent filter frames 310 in the art is applicable to this application. In addition, based on the rotating connection of the two adjacent filter frames 310, the relative position of the two adjacent filter frames 310 can also be limited by detachable methods such as snap-fit ​​or interference fit. This allows the two adjacent filter frames 310 to be fixed when the filter element 300 is in the receiving space, improving the installation stability of the filter element 300. When the filter element 300 passes through the installation opening, the fixation of the two filter frames 310 can be released to adjust the size of the filter element 300, facilitating the entry and exit of the filter element 300 from the receiving space.

[0074] In some embodiments, the filter element 300 is configured to be retractable. In the disassembled state, one part of the filter element 300 passes through the mounting opening 102 and the other part is retracted, so as to reduce the size of the filter element 300 in the direction in which the filter element 300 enters and exits the mounting opening 102.

[0075] In some embodiments, the filter element 300 is configured to be elastically deformable. In the disassembled state, one part of the filter element 300 passes through the mounting opening 102, and the other part deforms and shrinks to reduce the size of the filter element 300 in the direction in which the filter element 300 enters and exits the mounting opening 102.

[0076] In this application embodiment, the types of foldable filter element 300, rollable filter element 300 and elastically deformable filter element 300 are not limited. Any filter element 300 that can meet the above requirements in the art is applicable to this application.

[0077] In addition, the filter surface of the filter 320 in this embodiment can be a plane or an arc-shaped surface. When the filter surface is an arc-shaped surface, the filter surface protrudes from the side of the supporting base frame 100, and the protruding filter surface has a vertex furthest from the supporting base frame 100 in its protruding direction. The direction perpendicular to the filter surface can be the direction of the tangent perpendicular to the vertex of the filter surface.

[0078] This application also provides an air handling device, which can be a device for purifying, humidifying, or calibrating the air in the environment where the air handling device is located.

[0079] The air handling unit includes a body and a filter assembly 10 as described above. The body has an airflow channel, and the filter assembly 10 is installed at the port of the airflow channel so that the filter element 300 of the filter assembly 10 filters the gas entering and leaving the airflow channel.

[0080] The air handling equipment of this application embodiment, by employing the filter assembly 10 as described above, not only facilitates the disassembly and replacement of the filter element 300 and reduces the space constraints on the disassembly and assembly of the air handling equipment, but also allows for the selective installation of multiple limiting frames 200 of the filter assembly 10 onto the supporting base frame 100, so that the multiple structural components of the filter assembly 10 form a whole and move together to be aligned with the body of the air handling equipment, and then the multiple limiting frames 200 are installed on the body of the air handling equipment, thereby improving installation efficiency. In this installation method, after at least one of the limiting frames 200 is fixedly connected to the body of the air handling unit and the supporting base frame 100, the remaining limiting frames 200 are still installed on the body of the air handling unit, defining the installation opening 102. Thus, the filter element 300 can be disassembled and installed while the limiting frames 200 are still installed on the body of the air handling unit, without having to remove the entire filter assembly 10 from the body of the air handling unit. This is especially useful when the airflow channel is large, as the filter assembly 10 is also large and moving a large filter assembly 10 is difficult. However, in this application, only one or more limiting frames 200 and the filter element 300 need to be moved to disassemble and install the filter element 300, making the operation convenient.
