[0019] Preferred embodiment.

[0020] This embodiment provides an easily detachable, high-strength combined filter bag, including a first support frame 100, a second support frame 200, a first cover 300, and a first folded filter screen 500. The second support frame 200 is disposed within the first support frame 100. The lower end of the first support frame 100 is provided with a first bottom support plate 110, and the lower end of the second support frame 200 is provided with a second bottom support plate 210. The upper end of the first bottom support plate 110 is provided with a first annular protrusion 130, and the lower end of the second bottom support plate 210 is provided with a first annular groove 211. The first annular protrusion 130 and the first annular groove... 211 correspondence, the first folded filter screen 500 is disposed between the first support frame 100 and the second support frame 200. The upper end of the first support frame 100 is provided with a first connecting ring 120, the upper end of the second support frame 200 is provided with a second support ring, the first cover 300 is disposed at the upper end of the first support frame 100, and the lower end of the first cover 300 is provided with a first support groove 310 and a second support groove 320. The first support groove 310 matches the first support frame 100, and the second support groove 320 matches the second support frame 200.

[0021] Furthermore, the inner side of the first annular protrusion 130 is provided with a plurality of first mounting grooves 131, and the first mounting groove 131 is provided with a first spring 132 and a first stop block 140. One end of the first spring 132 is connected to the bottom of the first mounting groove 131, and the other end of the first spring 132 is connected to the first stop block 140. The inner side of the first annular groove 211 is provided with a plurality of second mounting grooves 212, and the second mounting grooves 212 correspond one-to-one with the first stop block 140.

[0022] Furthermore, the first folded filter 500 includes a plurality of first folds, and the first folded filter 500 is folded into a ring shape containing a plurality of first angles through the first folds.

[0023] Furthermore, the upper end of the second bottom support plate 210 is provided with a first retaining ring 230, and the outer side of the first retaining ring 230 is provided with a plurality of first retaining grooves, and the first bend corresponds one to one with the first retaining grooves.

[0024] Furthermore, the easily detachable high-strength combined filter bag includes a first base plate 400, on which a plurality of first wedge-shaped top blocks 410 are provided. The lower end of the first mounting groove 131 is provided with a first through hole 133, which corresponds one-to-one with the first wedge-shaped top blocks 410. The lower end of the first stop block 140 is provided with a first wedge-shaped groove 141, which matches the first wedge-shaped top blocks 410.

[0025] Working principle: First, the second support frame 200 is placed inside the first support frame 100, and the first annular protrusion 130 is inserted into the first annular groove 211. During the descent of the first annular protrusion 130, it pushes the first stop block 140 to move into the first mounting groove 131, ensuring that the first annular protrusion 130 is inserted into the first annular groove 211. The second support frame 200 is rotated. When the first mounting groove 131 and the second mounting groove 212 are aligned, the first spring 132 pushes the first stop block 140 into the second mounting groove 212, thereby locking the second support frame 200 and preventing it from falling off. Then, the first folded filter screen 500 is placed between the first support frame 100 and the second support frame 200. The first folded corner is locked in the first slot, which facilitates the fixation of the first folded filter screen 500. The first folded corner formed by the first fold increases the contact area of ​​the first folded filter screen 500, improves the filtration effect of the first folded filter screen 500, and also increases the structural stability of the first folded filter screen 500. The first cover plate is then placed over the upper end of the first support frame 100, which is inserted into the first support groove 310. The second support frame 200 is inserted into the second support groove 320, which secures the first cover plate and enhances the overall structural strength. During disassembly, the first support frame 100 is placed on the first base plate 400, allowing the first wedge-shaped top block 410 to insert into the first through hole 133. The first wedge-shaped top block 410, in conjunction with the first wedge-shaped groove 141, pushes the first stop block 140 into the first mounting groove 131, thereby allowing the second support frame 200 to be removed. This facilitates assembly and disassembly and provides higher structural strength.

[0026] It is worth mentioning that the technical features such as the first wedge groove 141 involved in this utility model patent application should be regarded as prior art. The specific structure, working principle and possible control method and spatial arrangement of these technical features can be adopted by conventional choices in the field, and should not be regarded as the utility model point of this utility model patent. This utility model patent will not be further elaborated in detail.

[0027] For those skilled in the art, modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
