Description

Technical Field

[0001] The present application relates to the technical field of air treatment, and in particular to a filter assembly and an air treatment device. Background Art

[0002] In the process of air treatment by air handling equipment, it is often necessary to filter the air through the filter assembly to prevent solid impurities in the air from entering the air handling equipment. In order to ensure the cleanliness of the air sent out by the air handling equipment, the filter assembly needs to be disassembled and cleaned regularly to avoid excessive accumulation of impurities on the filter assembly, which affects the air output efficiency and air cleanliness.

[0003] Existing air handling equipment such as Figure 1 The duct machine 8 shown in the figure is generally provided with a filter assembly 7 at the return air outlet of the unit to prevent dust or other debris from being sucked into the unit and affecting heat exchange. In order to achieve the installation of the filter assembly 7, two upper and lower horizontal slides are often provided at the return air outlet of the duct machine 8 box body, and the filter assembly 7 can slide left and right in the slide, so as to achieve the disassembly and assembly of the filter assembly 7 on the duct machine 8. This disassembly and assembly method requires a large surplus space on both sides of the slide to facilitate the extraction of the filter assembly 7. When the duct machine 8 is installed in a space with a relatively narrow horizontal spacing such as a corridor, the side walls 9 of the building on the left and right sides of the slide block the extraction of the filter assembly 7, resulting in the filter assembly 7 being unable to be conveniently removed from the slide of the duct machine, affecting the disassembly and assembly efficiency of the filter assembly 7, and even affecting the normal use of the air handling equipment in severe cases.

[0050] In order to make the purpose, technical solution and advantages of the embodiments of the present application clearer, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of this application.

[0051] The disclosure below provides many different embodiments or examples to realize the different structures of the present application. In order to simplify the disclosure of the present application, the parts and settings of specific examples are described below. Of course, they are only examples, and the purpose is not to limit the present application. In addition, the present application can repeat reference numbers and / or letters in different examples. This repetition is for the purpose of simplification and clarity, and does not itself indicate the relationship between the various embodiments and / or settings discussed.

[0052] For ease of description, spatial relative terms may be used herein to describe the relative positional relationship or movement of one element or feature relative to another element or feature as shown in the figure, such as "inside", "outside", "inner side", "outer side", "below", "below", "above", "above", "front", "back", etc. Such spatial relative terms are intended to include different orientations of the device in use or operation in addition to the orientation depicted in the figure. For example, if the device in the figure undergoes a position flip or a posture change or a motion state change, then these directional indications also change accordingly, for example: an element described as "below other elements or features" or "below other elements or features" will subsequently be oriented as "above other elements or features" or "above other elements or features". Therefore, the example term "below..." may include both upper and lower orientations. The device may be otherwise oriented (rotated 90 degrees or in other directions) and the spatial relative descriptors used herein are interpreted accordingly.

[0053] In the prior art, see Figure 1 The back of the air handling equipment such as the duct unit 8 is often provided with a horizontal slide for installing the filter assembly 7. The cross section of the horizontal slide is a U-shaped structure, so that the filter assembly 7 can only be pulled out from the left and right sides of the horizontal slide. When the distance between the two sides of the horizontal slide of the duct unit 8 and the side wall 9 of the building is small, the filter assembly 7 cannot be pulled out from the left and right sides of the horizontal slide, and the filter assembly 7 cannot be regularly cleaned and maintained, which is not conducive to ensuring the normal operation of the air handling equipment such as the duct unit 8.

[0054] In order to solve the technical problem in the prior art that the filter assembly 7 is easily limited by the installation space during disassembly and cannot be easily disassembled, the present application provides a filter assembly and an air treatment device, which can adjust the size of the filter assembly. When disassembling, the structural size of the filter assembly can be reduced to facilitate the removal of the filter assembly from the installation frame assembly 6 of the air treatment device, so that the filter assembly can be easily disassembled and assembled, and regular maintenance of the air treatment device can be easily achieved.

[0055] See also Figures 2 to 14In a first aspect, an embodiment of the present application provides a filter assembly, including a first frame 1, a second frame 2, a filter screen 3 and an elastic member 4. The first frame 1 and the second frame 2 are arranged relative to each other and can move relative to each other. The size of the entire filter assembly can be adjusted by the relative movement of the first frame 1 and the second frame 2. When the filter assembly needs to be disassembled, the first frame 1 and the second frame 2 are moved closer to each other, so that the size of the filter assembly is reduced, which facilitates the removal of the filter assembly from the air handling device.

[0056] The two ends of the filter 3 are connected to the first frame 1 and the second frame 2 respectively. The filter 3 is a flexible structure and can be deformed with the relative movement of the first frame 1 and the second frame 2. The elastic member 4 always has a tendency to make the first frame 1 away from the second frame 2. When the filter assembly needs to be disassembled, the first frame 1 and the second frame 2 overcome the elastic force of the elastic member 4 and approach each other, so that the size of the filter assembly is reduced; when the filter assembly is in normal use, the first frame 1 and the second frame 2 are away from each other under the elastic force of the elastic member 4, so that the filter assembly returns to its normal size, so that the first frame 1 and the second frame 2 can be accurately installed in the installation frame assembly 6 of the air handling device, and the filter 3 is in a taut state, which is conducive to filtering impurities in the air.

[0057] In the above embodiment, if the first frame 1 and the second frame 2 are respectively connected to the upper and lower horizontal slides in the air handling device, the overall height of the filter assembly can be changed by bringing the first frame 1 and the second frame 2 closer to each other, so that the upper and lower ends of the filter assembly can be taken out from the horizontal slides behind the air handling device. Even if the horizontal distance between the air handling device and the side wall 9 of the building is small and the disassembly range is limited, it does not affect the placement and removal of the filter assembly.

[0058] It should be noted that when the relative movement direction between the first frame 1 and the second frame 2 is in the vertical direction, the longitudinal height dimension of the filter assembly can be changed by the relative movement between the first frame 1 and the second frame 2, which is suitable for use scenarios where the left and right disassembly and assembly space is limited. When the relative movement direction between the first frame 1 and the second frame 2 is in the horizontal direction, the lateral width dimension of the filter assembly can be changed by the relative movement between the first frame 1 and the second frame 2, which is suitable for use scenarios where the upper and lower disassembly and assembly space is limited.

[0059] It should be noted that the relative motion between the first frame 1 and the second frame 2 can be realized by a variety of connection forms. In some embodiments of the present application, the first frame 1 and the second frame 2 are directly slidably connected, and the relative motion is realized by the relative sliding between the two. In other embodiments of the present application, the first frame 1 and the second frame 2 can be indirectly connected by an intermediate component (such as a sleeve, a slide rail, etc.), and the relative motion between the first frame 1 and the second frame 2 is realized by sliding the first frame 1 and / or the second frame 2 relative to the intermediate component. Correspondingly, the arrangement of the elastic member 4 can be directly connected to the first frame 1 and the second frame 2, and can also be arranged between the intermediate component and the movable frame to realize the resetting of the filter assembly.

[0060] It should be noted that the connection between the edge of the filter 3 and the first frame 1 and the second frame 2 can be formed as an integral connection by injection molding or the like, or can be formed as a detachable connection by a structure such as a snap, or the filter 3 can include a plurality of flexible wires, and the first frame 1 and the second frame 2 have a plurality of connecting holes that can be used to connect to the two ends of the flexible wires, which is not limited here.

[0061] In some embodiments of this application, please refer to Figure 2 , Figure 5 , Figure 7 and Fig. 9 The first frame 1 and the second frame 2 are both semi-enclosed frames, that is, frames with an opening on one side, and the opening area can avoid interference with the middle of the filter 3, such as a U-shaped frame, and the installation space of the filter 3 is formed by enclosing two semi-enclosed frames. A rigid frame structure can be formed around the filter 3 by the first frame 1 and the second frame 2, which is conducive to the installation and protection of the filter 3.

[0062] Specifically, the first frame 1 and the second frame 2 are both bilaterally symmetrical structures. The first frame 1 includes a first connecting rod 14 and first side rods 13 disposed on both sides of the first connecting rod 14, and the second frame 2 includes a second connecting rod 22 and second side rods 23 disposed on both sides of the second connecting rod 22. The first side rod 13 is slidably connected to the second side rod 23 on the corresponding side, thereby achieving relative sliding between the first frame 1 and the second frame 2.

[0063] It should be noted that the first frame 1 and the second frame 2 can be made by bending high-strength and high-toughness materials such as steel (such as steel wire, steel pipe), so that the first frame 1 and the second frame 2 are bent into a U-shaped structure.

[0064] It should be noted that, in the above embodiment, the sliding connection between the first side rod 13 and the second side rod 23 can be achieved by setting one of the side rods as a tube, or by setting mutually matching guide structures on the first side rod 13 and the second side rod 23.

[0065] In some embodiments of this application, please refer to Figure 3 , Figure 4 and Fig.10 The first frame body 1 has a first guide portion 11, and the second frame body 2 has a second guide portion 21. The first guide portion 11 is slidably connected to the second guide portion 21, so that the first frame body 1 and the second frame body 2 can slide along a preset direction to avoid deflection between the first frame body 1 and the second frame body 2, which affects the size adjustment of the filter assembly.

[0066] It should be noted that the guidance between the first guide portion 11 and the second guide portion 21 can be achieved through a guide structure such as a groove and a ridge, or through a guide structure such as a guide sleeve and a slide rod.

[0067] Specifically, the first guide portion 11 is disposed on the first side rod 13, and the second guide portion 21 is disposed on the second side rod 23, so as to guide the relative movement between the first side rod 13 and the second side rod 23. When the first guide portion 11 and the second guide portion 21 are slidably guided by guide structures such as guide sleeves and slide bars, the first guide portion 11 is disposed at the end of the first side rod 13, and the second guide portion 21 is disposed at the end of the second side rod 23, such as Figure 5 and Figure 7 shown.

[0068] Specifically, the first guide portion 11 is a cylindrical structure, and the second guide portion 21 is slidably disposed in the cylindrical structure, and the cylindrical structure is used to realize sliding guidance for the second guide portion 21, such as Figure 4 and Fig.10 shown.

[0069] In the above embodiment, in order to facilitate the installation of the elastic member 4 while reducing the size of the elastic member 4, the elastic member 4 is preferably arranged on both sides of the first frame 1 and the second frame 2, and the elastic force of the elastic member 4 causes relative sliding between the first side rod 13 and the second side rod 23.

[0070] In some embodiments of this application, please refer to Figure 2 , Figure 3 and Figure 4 The elastic member 4 is arranged inside the cylindrical structure, and the second guide portion 21 is inserted into the cylindrical structure. Along the extension and contraction direction of the elastic member 4, the two ends of the elastic member 4 are respectively abutted against the cylindrical structure and the second guide portion 21, so that the installation of the elastic member 4 can be realized, and the elastic member 4 is protected by the cylindrical structure to prevent the elastic member 4 from being exposed. At the same time, the second guide portion 21 can realize sliding guidance through the first guide portion 11.

[0071] Specifically, the second guide portion 21 is inserted into the cylindrical structure of the first guide portion 11, and the end of the second guide portion 21 can be provided with a concave cavity for accommodating the elastic member 4, the upper end of the elastic member 4 abuts against the top of the concave cavity, and the lower end of the elastic member 4 abuts against the bottom of the cylindrical structure, such as Figure 4 and Figure 8 As shown, the elastic member 4 can be limited and guided by the cylindrical structure and the concave cavity. Figure 4 When the elastic member 4 is extended or retracted in the vertical direction, it can be prevented from tilting inside the first guide portion 11 and the second guide portion 21, so that it can only be extended or retracted in the sliding direction of the first frame body 1 and the second frame body 2.

[0072] In other embodiments of the present application, please refer to Fig. 9 and Fig.10 The elastic member 4 is sleeved on the outside of the first guide portion 11 and the second guide portion 21. Along the extension direction of the elastic member 4, the two ends of the elastic member 4 are respectively connected to the first frame 1 and the second frame 2. When the first guide portion 11 and the second guide portion 21 move relative to each other, the elastic member 4 also extends and contracts accordingly. At this time, there is no need to set a concave cavity on the second guide portion 21 for accommodating the elastic member 4. The elastic member 4 can achieve extension and limit and guidance through the outer walls of the first guide portion 11 and the second guide portion 21.

[0073] Specifically, the elastic member 4 is wound around the first guide portion 11 or the second guide portion 21, and then the second guide portion 21 is inserted into the cylindrical structure of the first guide portion 11, a certain sliding guide depth is reserved inside the cylindrical structure, and then the upper and lower ends of the elastic member 4 are fixedly connected to the first side rod 13 and the second side rod 23 by welding or other methods, so that the elastic member 4 can be assembled. The length of the elastic member 4 is much greater than the length of the sliding guide depth formed by the first guide portion 11 and the second guide portion 21. When the filter assembly is set in the installation frame assembly 6, the elastic member 4 is always in a compressed state, so that the first frame body 1 and the second frame body are separated from each other under the action of elastic force, thereby achieving the tightening of the filter screen 3 and the stable installation of the filter assembly. During the disassembly and assembly process, when the first guide portion 11 and the second guide portion 21 slide relative to each other in the vertical direction, the elastic member 4 also expands and contracts in the vertical direction accordingly.

[0074] In the above embodiment, when the filter assembly needs to be removed from the mounting frame assembly 6, the first frame body 1 and the second frame body 2 can be moved closer to each other by hand or with the aid of a tool. Specifically, the first side bar 13 and the second side bar 23 can be directly pulled by hand or with a tool, so that the first side bar 13 and the second side bar 23 overcome the elastic force of the elastic member 4 and move closer to each other, thereby reducing the distance between the first connecting rod 14 and the second connecting rod 22, reducing the overall size of the filter assembly, and facilitating direct removal of the filter assembly from the mounting frame assembly 6.

[0075] In the above embodiment, when the filter assembly is installed on the air handling device, since the gap between the first frame body 1, the second frame body 2 and the mounting frame assembly 6 is small, if the filter assembly is compressed by directly pulling the first side rod 13 and the second side rod 23 manually, since both the first side rod 13 and the second side rod 23 are in contact with the mounting frame assembly 6, it may be inconvenient to apply force to the first side rod 13 and the second side rod 23 due to the small operating space. If the first side rod 13 and / or the second side rod 23 are clamped by a tool, and then the first side rod 13 and the second side rod 23 are pulled by the tool to compress the filter assembly, the disassembly process will be cumbersome and the disassembly efficiency will be low.

[0076] In order to solve the above problems, in some embodiments of the present application, please refer to Figure 2 and Fig. 9 The first frame 1 and the second frame 2 are both provided with operating members 5, which are protruding from the first frame 1 or the second frame 2 and are used to drive the first frame 1 and the second frame 2 to move relative to each other. When the operating members 5 on both sides of the filter assembly are pressed by both hands, the first frame 1 and the second frame 2 can be brought closer to each other, thereby adjusting the size (i.e., height) of the filter assembly, and it is convenient to pinch the operating member 5 to take out the filter assembly.

[0077] Specifically, a first operating member 5a is vertically arranged on the first side rods 13 on both sides of the first frame body 1, and a second operating member 5b is vertically arranged on the second side rods 23 on both sides of the second frame body 2. By pinching the first operating member 5a and the second operating member 5b, the first side rod 13 and the second side rod 23 can slide relative to each other, so that the first connecting rod 14 and the second connecting rod 22 are close to each other, thereby reducing the overall size of the filter assembly.

[0078] In the above embodiment, if the elastic member 4 is Figure 4 The method shown is installed inside the first guide part 11 and the second guide part 21, which is not convenient for fixing the two ends of the elastic member 4. The two ends of the elastic member 4 are only in contact with the first guide part 11 and the second guide part 21. After the filter assembly is taken out, if the second guide part 21 slides out of the first guide part 11 under the push of the elastic member 4, the rectangular frame of the filter assembly will disintegrate.

[0079] In order to solve the above problems, in some embodiments of the present application, please refer to Figure 3 and Figure 4A limiting slide groove 12 is provided on the first frame body 1, and the limiting slide groove 12 has an opening. The operating member 5 on the second frame body 2 passes through the limiting slide groove 12 from the opening of the limiting slide groove 12, and the free end of the operating member 5 protrudes from the limiting slide groove 12. The operating member 5 can slide back and forth along the length direction of the limiting slide groove 12, which is convenient for adjusting the size of the filter assembly. Since the groove walls at both ends of the length direction of the limiting slide groove 12 have a limiting effect on the second operating member 5b, the second operating member 5b can be prevented from escaping from the limiting slide groove 12, thereby preventing the first frame body 1 and the second frame body 2 from being separated, causing the rectangular frame of the filter assembly to disintegrate.

[0080] Specifically, the limiting chute 12 is provided on the side wall of the cylindrical structure (i.e., the first guide portion 11), the second operating member 5b is provided on the second side rod 23 or the outer wall of the second guide portion 21, and the second operating member 5b extends out of the limiting chute 12, and can slide inside the first guide portion 11 along with the second guide portion 21, and is limited by the groove walls on both sides of the length direction of the limiting chute 12. The elastic member 4 inside the cylindrical structure (i.e., the first guide portion 11) has a pre-compression amount, and the pre-compression amount of the elastic member 4 is greater than the length of the limiting chute 12. When the first guide portion 11 and the second guide portion 21 slide relative to each other, the elastic member 4 is always in a compressed state, so that when the filter assembly is not subjected to external force, the first frame 1 and the second frame 2 can be extended and reset under the action of the elastic member 4.

[0081] In the above embodiment, in order to prevent the second operating member 5b from interfering with the assembly between the first guide portion 11 and the second guide portion 21, in some embodiments of the present application, the operating member 5 is detachably arranged on the first frame body 1 or the second frame body 2. After the elastic member 4 and the second guide portion 21 are placed in the first guide portion 11, the second operating member 5b is installed on the second side rod 23 or the second guide portion 21, and the overall assembly of the filter assembly can be achieved.

[0082] The detachable connection between the operating member 5 and the first frame body 1 and / or the second frame body 2 can be achieved by threaded connection, clamping, etc. Specifically, a threaded hole or a clamping hole is provided on the second guide portion 21, and after the second guide portion 21 is inserted into the first guide portion 11 (i.e., the cylindrical structure), one end of the second operating member 5b is extended into the limiting slide groove 12 and inserted into the threaded hole or the clamping hole, so as to achieve the connection between the second operating member 5b and the second guide portion 21.

[0083] In the above embodiment, since the first operating member 5a has no influence on the assembly of the filter assembly, the first operating member 5a and the first side rod 13 can be configured as an integrated structure, which is helpful to reduce the difficulty of assembly.

[0084] It should be noted that when the elastic member 4 is Fig. 9 and Fig.10When the first operating member 5a and the second operating member 5b are sleeved outside the first guide portion 11 and the second guide portion 21 in the manner shown, since the first operating member 5a and the second operating member 5b have no influence on the assembly of other components, the first operating member 5a and the first side rod 13 can be set as an integrated structure, and the second operating member 5b and the second side rod 23 can be set as an integrated structure, which is conducive to reducing the number of parts and reducing the difficulty of assembly. At this time, the two ends of the elastic member 4 in the extension direction can be fixedly connected (by welding or the like) to the first operating member 5a and the second operating member 5b respectively.

[0085] It should be noted that when the upper and lower ends of the filter screen 3 are connected to the first connecting rod 14 and the second connecting rod 22 respectively, the left and right sides of the filter screen 3 can also be connected to the first side rod 13 and the second side rod 23, so as to improve the reliability of the connection between the filter screen 3 and the rectangular frame in the circumferential direction. The connection areas on the left and right sides avoid the areas where the first guide portion 11, the second guide portion 21, the first operating member 5a and the second operating member 5b are located, so as to avoid affecting the relative sliding between the first guide portion 11 and the second guide portion 21.

[0086] The second aspect of the present application provides an air treatment device, see Fig.11 , including the filter component in the above embodiment, and also including a mounting frame component 6, in which the filter component is detachably arranged.

[0087] It should be noted that the air handling equipment may be a fan, a duct machine 8, an air conditioner, or other equipment that needs to filter the air.

[0088] Since the structural dimensions of the mounting frame assembly 6 are fixed, when the distance between the first connecting rod 14 and the second connecting rod 22 is H, it can be adapted to the dimensions of the mounting frame assembly 6, and the filter assembly can be accurately arranged inside the mounting frame assembly 6. When the filter assembly needs to be disassembled, the first operating member 5a and the second operating member 5b are pinched, and the distance between the first connecting rod 14 and the second connecting rod 22 is reduced to h. At this time, h is smaller than the height or width of the mounting frame assembly 6, and the filter assembly can be taken out of the mounting frame assembly 6 without sliding the filter assembly out from the left side, right side, upper side or lower side of the mounting frame assembly 6, which is suitable for installing the air handling equipment of the present application in narrow areas such as corridors.

[0089] In some embodiments of this application, please refer to Fig.12 , Fig.13 and Fig.14 A sealing gasket 61 is provided along the circumference of the mounting frame assembly 6 to abut against the frame of the filter assembly to prevent gas leakage in the edge gap between the filter assembly and the mounting frame assembly 6, thereby affecting the filtering effect. Specifically, the sealing gasket 61 is provided on the side of the mounting frame assembly 6 facing the filter assembly, such as Fig.13 Specifically, the sealing pad 61 can be made of materials such as silica gel and rubber.

[0090] In some embodiments of this application, please refer to Fig.12 and Fig.13 The mounting frame assembly 6 includes a first snap-fit ​​groove 62 and a second snap-fit ​​groove 63 that are arranged opposite to each other. The first frame body 1 and the second frame body 2 are respectively embedded in the first snap-fit ​​groove 62 and the second snap-fit ​​groove 63 to prevent the filter assembly from falling out of the mounting frame assembly 6 during use.

[0091] Specifically, the cross-sections of the first clamping groove 62 and the second clamping groove 63 are both U-shaped structures. When the first connecting rod 14 and the second connecting rod 22 are inserted into the first clamping groove 62 and the second clamping groove 63, the operating member 5 is released, and the first frame 1 and the second frame 2 move away from each other under the action of the elastic member 4. The first connecting rod 14 and the second connecting rod 22 are embedded in the U-shaped structure, which can prevent the upper and lower ends of the filter assembly from falling out of the first clamping groove 62 and the second clamping groove 63.

[0092] As a specific embodiment of the present application, the length direction of the first snap-fit ​​groove 62 and the second snap-fit ​​groove 63 is parallel to the horizontal direction. At this time, by pinching the first operating member 5a and the second operating member 5b, the height distance between the first connecting rod 14 and the second connecting rod 22 is reduced to h. At this time, h is smaller than the distance between the first snap-fit ​​groove 62 and the second snap-fit ​​groove 63, and the filter assembly can be removed from the mounting frame assembly 6.

[0093] In some embodiments of the present application, the mounting frame assembly 6 further includes two side baffles 64 arranged opposite to each other. The cross section of the side baffles 64 is an L-shaped structure, which can prevent the filter assembly from sliding out from the left and right sides of the mounting frame assembly 6. A sealing gasket 61 is provided on one side of the side baffle 64 facing the filter assembly, which can be used to abut against the left and right sides of the filter assembly to achieve sealing. Fig.12 and Fig.14 shown.

[0094] In some embodiments of this application, please refer to Fig.13 The first clamping groove 62 and the second clamping groove 63 are provided with an elastic pad 65, which can be used to abut against the frame of the filter assembly to prevent the filter assembly from shaking in the vertical direction. Specifically, the elastic pad 65 can be made of materials such as sponge.

[0095] It should be noted that, through the joint action of the sealing pad 61 and the elastic pad 65, the horizontal and vertical limiting of the filter assembly inside the mounting frame assembly 6 can be achieved respectively, thereby preventing the filter assembly from shaking and making abnormal noises inside the mounting frame assembly 6.

[0096] In some embodiments of the present application, the mounting frame assembly 6 is disposed at the back of the air handling device, which can avoid affecting the front appearance of the air handling device. As a specific embodiment of the present application, when the air handling device is a duct machine 8, the mounting frame assembly 6 is disposed at the return air outlet at the back of the duct machine 8, and the filter assembly can be taken in and out from the rear of the air handling device (i.e., the duct machine 8).

[0097] It should be noted that one or more filter assemblies can be arranged in the same mounting frame assembly 6, and the number of filter assemblies is determined according to the size of the mounting frame assembly 6. Specifically, when the length of the first clamping slot 62 and the second clamping slot 63 is long, multiple filter assemblies can be arranged in sequence along the length direction of the first clamping slot 62 or the second clamping slot 63, so as to filter the air at the air inlet or the air outlet. Fig.11 shown.

[0098] See also Figures 2 to 14 In some embodiments of the present application, the disassembly and assembly method of the above-mentioned filter assembly is as follows:

[0099] Step 1: When the filter assembly is set on the mounting frame assembly 6, the first operating member 5a and the second operating member 5b are squeezed by both hands to bring the first frame body 1 and the second frame body 2 closer to each other, so that the height dimension of the filter assembly is reduced;

[0100] Step 2: When the height of the filter assembly is smaller than the distance between the first clamping groove 62 and the second clamping groove 63, the filter assembly is taken out backward as a whole; the first operating member 5a and the second operating member 5b are released, and the size of the filter assembly is restored under the action of the elastic member 4;

[0101] Step 3: After completing the maintenance of the filter assembly, pinch the first operating member 5a and the second operating member 5b with both hands to bring the first frame 1 and the second frame 2 closer to each other, so that the height of the filter assembly is reduced;

[0102] Step 4: When the height of the filter assembly is smaller than the distance between the first clamping groove 62 and the second clamping groove 63, the filter assembly is placed forward into the mounting frame assembly 6, and the front side of the filter assembly contacts the sealing gasket 61 on the mounting frame assembly 6;

[0103] Step 5: When the first connecting rod 14 and the first snap-fit ​​groove 62 are opposite to each other in the vertical direction, and the second connecting rod 22 and the second snap-fit ​​groove 63 are opposite to each other in the vertical direction, release the first operating member 5a and the second operating member 5b, and the size of the filter assembly is restored under the action of the elastic member 4; the top of the filter assembly contacts the elastic pad 65 in the first snap-fit ​​groove 62, and the bottom of the filter assembly contacts the elastic pad 65 in the second snap-fit ​​groove 63, and the installation of the filter assembly is completed.
