[0022] The following is a description of the preferred embodiments of the present utility model with reference to the accompanying drawings. It should be understood that the preferred embodiments described herein are only for the purpose of illustrating and explaining the present utility model, and are not used to limit the present utility model.

[0023] Embodiment: As Figures 1-4 shown, a filter screen for an air purification device of the present utility model includes a first frame 1 and a second frame 2, and a quick disassembly and assembly mechanism 3 is provided between the first frame 1 and the second frame 2.

[0024] The quick disassembly and assembly mechanism 3 includes a filter screen main body 6. Fixing plates 7 are fixedly connected to the middle parts of the left and right walls of the filter screen main body 6. By fixing the fixing plates 7, the filter screen main body 6 can be fixed between the first frame 1 and the second frame 2. The fixing plates 7 are both arranged between two groups of clamping grooves 5. The clamping grooves 5 are respectively arranged at the upper and lower parts of the left and right sides of the adjacent sides of the first frame 1 and the second frame 2. Mounting plates 11 are arranged at the upper and lower parts of the left and right walls of the first frame 1 and the second frame 2. Sliding grooves 12 are arranged in the middle parts of the mounting plates 11. Bidirectional screws 13 are rotatably connected to the inner sides of the sliding grooves 12. Connecting plates 14 are threadedly connected to the front and rear parts of the outer circumference of the bidirectional screws 13. Clamping plates 16 are fixedly connected to the adjacent ends of the left and right connecting plates 14. The clamping plates 16 can apply a force to make the first frame 1 and the second frame 2 approach each other.

[0025] Among them, card slots 4 are arranged at the upper and lower parts of the left and right ends of the sides of the first frame 1 and the second frame 2 away from each other. The card slots 4 are in clearance fit with the clamping plates 16, and the card slots 4 provide space for storing the clamping plates 16.

[0026] Among them, the fixing plates 7 are in clearance fit with the clamping grooves 5, and the filter screen main body 6 is arranged inside between the first frame 1 and the second frame 2.

[0027] Among them, positioning rods 9 are fixedly connected to the upper and lower ends of the middle parts of the clamping grooves 5 on the front side of the first frame 1, and positioning tubes 10 are fixedly connected to the upper and lower ends of the middle parts of the clamping grooves 5 on the rear side of the second frame 2. The positioning tubes 10 and the positioning rods 9 cooperate to determine the positions of the through holes 8.

[0028] Among them, through holes 8 are provided on both the upper and lower sides of the middle part of the fixed plate 7, and the through holes 8 are in clearance fit with the positioning tubes 10.

[0030] Among them, the first frame 1 and the second frame 2 are symmetrically arranged. The width of the mounting plate 11 is greater than the sum of the widths of the first frame 1 and the second frame 2. Knobs 15 are fixedly connected to the front ends of the bidirectional screws 13, and rotating the knobs 15 can make the bidirectional screws 13 rotate.

[0031] Working principle: When the filter screen body needs to be replaced, rotate the knob 15. During the rotation of the knob 15, the bidirectional screw 13 rotates. During the rotation of the bidirectional screw 13, the front and rear clamping plates 16 move away from each other, so as to release the clamping of the first frame 1 and the second frame 2. Then, the internal filter screen body 6 can be taken out for replacement. After the replacement is completed, the filter screen body 6 can be quickly positioned under the cooperation of the positioning rod 9, the positioning tube 10, the through hole 8 and the fixed plate 7. Then, rotate the knob 15 in the reverse direction to make the bidirectional screw 13 rotate in the reverse direction, and make the first frame 1 and the second frame 2 fit and fix, which is convenient for subsequent clamping and fixing operations.
