[0032] The following is for reference. Figures 1 to 6 The filter framework of the first aspect of this application will be described in detail.

[0033] refer to Figures 1 to 3 According to a first aspect embodiment of the present invention, the filter frame includes a first frame 100 and a second frame 200; the first frame 100 includes a base plate 110 and a first side plate 120, the base plate 110 is connected to a first side plate 120 at opposite ends in a first horizontal direction, the base plate 110 is provided with first through holes 111 spaced apart along the first horizontal direction, and a first connecting portion 112 is formed between two adjacent first through holes 111, the first side plate 120 is provided with a first flange 121 and a second flange 122 at both ends in a second horizontal direction, the second horizontal direction being spaced at a certain angle from the first horizontal direction; the second frame 200 includes a top plate 210 and a second... A second side plate 220 is connected to each of the opposite ends of the side plate 220 and the top plate 210 in the second horizontal direction. The top plate 210 is provided with second through holes 211 spaced apart in the first horizontal direction. A second connecting part 212 is formed between two adjacent second through holes 211. The first connecting part 112 and the second connecting part 212 are alternately distributed in the first horizontal direction. The first connecting part 112 and the second connecting part 212 adjacent in the first horizontal direction are respectively used to connect to the opposite ends of the same filter element. The second side plate 220 is located between two first side plates 120, and the first flange 121 and the second flange 122 respectively abut against the plate surfaces of the two second side plates 220 that are opposite to each other.

[0034] For example, such as Figures 1 to 3 As shown, the filter frame includes a first frame 100 and a second frame 200. The first frame 100 includes a base plate 110 and two first side plates 120. The two first side plates 120 are respectively connected to the left and right ends of the base plate 110. The base plate 110 has first through holes 111 spaced apart from each other. The first through holes 111 are elongated holes extending in the front-back direction. A first connecting part 112 is formed between two adjacent first through holes 111. The front end of the first side plate 120 has a first flange 121, and the rear end of the first side plate 120 has a second flange 122. For the left first side plate 120, both its first flange 121 and second flange 122 extend to the right. For the right first side plate 120, both its first flange 121 and second flange 122 extend to the left. The second frame 200 includes a top plate 210 and two second side plates 220. The two second side plates 220 are connected to the front and rear ends of the top plate 210, respectively. The top plate 210 is located above the bottom plate 110. The top plate 210 is provided with second through holes 211 spaced apart in the left and right direction. A second connecting part 212 is formed between two adjacent second through holes 211. The first connecting part 112 and the second connecting part 212 are alternately distributed in the left and right direction, and the first through hole 111 and the second through hole 211 are alternately distributed in the left and right direction. The two second side plates 220 are located between two first side plates 120. The first flange 121 abuts against the front plate surface of the second side plate 220 located at the front end, and the second flange 122 abuts against the rear plate surface of the second side plate 220 located at the rear end.

[0035] It is understood that the first frame 100 includes a base plate 110 and a first side plate 120. The base plate 110 is connected to a first side plate 120 at each of its opposite ends in the first horizontal direction. The second frame 200 includes a top plate 210 and a second side plate 220. The top plate 210 is connected to a second side plate 220 at each of its opposite ends in the second horizontal direction. Thus, both the first frame 100 and the second frame 200 can be processed from U-shaped blanks, and the first frame 100 and the second frame 200 can be directly spliced ​​to form a filter frame. This eliminates the need to weld multiple metal plates piece by piece to form the entire filter frame, simplifying the manufacturing process of the filter frame and reducing the manufacturing difficulty of the filter frame.

[0036] Understandably, when the first frame 100 and the second frame 200 are assembled, the workers can insert the second frame 200 into the first frame 100 from top to bottom. During this process, the two second side panels 220 are inserted between the two first side panels 120. The first flange 121 and the second flange 122 are designed to guide the second frame 200 to be assembled onto the first frame 100 from top to bottom, or to guide the second frame 200 to be separated from the first frame 100 from bottom to top.

[0037] It is understood that when the filter frame of this application is used, the first connecting part 112 and the second connecting part 212 adjacent in the first horizontal direction are respectively connected to the upper end and the lower end of the same filter element. At this time, air can flow from the first through hole 111 to the filter element, and after passing through the filter element, it flows out from the second through hole 211 to achieve air filtration and purification.

[0038] In some embodiments of this utility model, the first side plate 120 is provided with a third flange 123 at one end away from the bottom plate 110. The third flange 123 abuts against the top plate 210. A first gap 124 is left between the third flange 123 and the first flange 121 to allow the second side plate 220 to pass through. A second gap 125 is left between the third flange 123 and the second flange 122 to allow the second side plate 220 to pass through.

[0039] For example, such as Figures 3 to 5 As shown, the upper end of the first side plate 120 is provided with a third flange 123, a first gap 124 is left between the third flange 123 and the first flange 121 to allow the second side plate 220 to pass through, and a second gap 125 is left between the third flange 123 and the second flange 122 to allow the second side plate 220 to pass through.

[0040] Understandably, when assembling the first frame 100 and the second frame 200, the workers can drive the second frame 200 from top to bottom to approach the first frame 100, so that the second side plate 220 located on the front side moves downward through the first gap 124, and the second side plate 220 located on the rear side moves downward through the second gap 125, until the third flange 123 abuts against the lower surface of the top plate 210.

[0041] It is understandable that the setting of the first gap 124 and the second gap 125 allows the gap wall of the first gap 124 to guide the second side plate 220 located on the front side to move in the vertical direction, and the gap wall of the second gap 125 to guide the second side plate 220 located on the rear side to move in the vertical direction, thereby making the movement of the second frame 200 in the vertical direction more precise.

[0042] In some embodiments of this utility model, the bottom plate 110 is provided with a fourth flange 113 and a fifth flange 114 at both ends in the second horizontal direction, and the fourth flange 113 and the fifth flange 114 respectively abut against the plate surfaces of the two second side plates 220 that are opposite to each other.

[0043] For example, such as Figure 3As shown, the front end of the base plate 110 is provided with an upwardly extending fourth flange 113, and the rear end of the base plate 110 is provided with an upwardly extending fifth flange 114. The fourth flange 113 abuts against the front surface of the second side plate 220 located on the front side, and the fifth flange 114 abuts against the rear surface of the second side plate 220 located on the rear side.

[0044] Understandably, the fourth flange 113 and the fifth flange 114 are designed to work together to limit the two second side panels 220 in the front-back direction, thereby limiting the second frame 200 in the front-back direction and reducing the probability of the second frame 200 being misaligned relative to the first frame 100 in the front-back direction under the influence of external forces.

[0045] In some embodiments of this utility model, the first through hole 111 is provided with a vertically extending sixth flange 115 on both sides of the hole edge in the first horizontal direction.

[0046] For example, such as Figure 3 As shown, the left and right sides of the first through hole 111 are provided with a vertically extending sixth flange 115.

[0047] Understandably, the sixth flange 115 is designed so that when the filter element is connected to the first connecting part 112, the sixth flange 115 located at the left and right ends of the first connecting part 112 can cooperate to limit the filter element in the left and right direction.

[0048] In some embodiments of this utility model, the second through hole 211 is provided with a vertically extending seventh flange 213 on both sides of the hole edge in the first horizontal direction.

[0049] For example, such as Figure 6 As shown, the second through hole 211 has a vertically extending seventh flange 213 on both the left and right sides of the hole.

[0050] Understandably, the seventh flange 213 is designed so that when the filter element is connected to the second connecting part 212, the seventh flange 213 located at the left and right ends of the second connecting part 212 can cooperate to limit the filter element in the left and right direction.

[0051] In some embodiments of this utility model, the base plate 110 and the first side plate 120 are integrally formed.

[0052] Understandably, by making the base plate 110 and the first side plate 120 homogeneous and integral, the first frame 100 can be manufactured as a single piece, reducing the manufacturing difficulty of the first frame 100.

[0053] In some embodiments of this utility model, the top plate 210 and the second side plate 220 are integrally formed.

[0054] Understandably, by making the top plate 210 and the second side plate 220 homogeneous and integral, the second frame 200 can be manufactured as a single piece, thus reducing the manufacturing difficulty of the second frame 200.

[0055] The filter provided according to a second aspect embodiment of the present invention includes the filter frame provided in the first aspect embodiment of the present invention.

[0056] In some embodiments of this utility model, the filter further includes multiple filter elements, with the first connecting portion 112 and the second connecting portion 212 adjacent in the first horizontal direction respectively connected to the opposite ends of the same filter element.

[0057] It is understood that the first connecting part 112 can be connected to two adjacent filter elements at the same time, and the second connecting part 212 can be connected to two adjacent filter elements at the same time, so that each filter element in the filter frame is connected end to end to cooperate in separating the first through hole 111 and the second through hole 211. The air flowing between the first through hole 111 and the second through hole 211 can pass through the filter element, thereby improving the filtration effect of the filter.

[0058] In some embodiments of this utility model, the junction between the filter element and the first connecting part 112 is filled with glue, and the junction between the filter element and the second connecting part 212 is filled with glue.

[0059] Understandably, the two ends of the filter element are connected to the first connecting part 112 and the second connecting part 212 with glue, which reduces the difficulty of installing the filter element in the filter frame and also reduces the difficulty of removing the filter element from the filter frame.

[0060] Although embodiments of the present invention have been shown and described, those skilled in the art will understand that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the claims and their equivalents.
