[0032] REFERENCE Figure 1 - Figure 2The utility model provides an embodiment: a kind of range hood filter assembly, control screen 2 is fixedly connected on the front upper side of rack 1, control screen 2 can control the electrical device being arranged in the inside of rack 1, the upper end of rack 1 is fixedly connected with smoke column 3, the front surface of rack 1 is equipped with air inlet 4, when the motor inside the rack 1 drives one or more fan (impeller) rotation generates negative pressure, oil fume will be extracted through air inlet 4, and after filtering, it is discharged quickly by the upper smoke column 3 connected smoke pipe, above structure is prior art means in the field, not described here, detachably connected with filter plate 5 in the inside of air inlet 4, the size of filter plate 5 and the size of air inlet 4 are mutually adapted, flue gas can enter the inside of rack 1 by the opening on filter plate 5.

[0033] Refer to Figure 3 - Figure 5 Rectangular edge slot 6 is equipped on the front surface of filter plate 5, electric heating wire group 7 is fixedly connected with the back of filter plate 5, electric heating wire group 7 is electrically connected between control screen 2, electric heating wire group 7 is embedded in the back of filter plate 5, user can directly control whether electric heating wire group 7 is powered on or not by control screen 2, electric heating wire group 7 can quickly generate heat after being powered on, and the edge of filter plate 5 is quickly heated, filter screen 8 is detachably connected with the front surface of filter plate 5, the size of electric heating wire group 7 and the size of filter screen 8 are mutually adapted, when electric heating wire group 7 generates heat after being powered on, the connecting position of the edge of filter screen 8 and the front surface of filter plate 5 can be heated, and the solidified oil adhered to the connecting position can be quickly heated and softened, reducing the obstruction of oil when filter screen 8 is detached, avoiding the need to pull filter screen 8 when filter screen 8 is detached, which can cause deformation and damage of filter screen 8.

[0034] Rectangular magnetic frame 9 is fixedly connected with the back of filter screen 8, rectangular magnetic frame 9 is inserted into the inside of rectangular edge slot 6, and rectangular magnetic frame 9 moves synchronously when filter screen 8 moves, when filter screen 8 is installed, rectangular magnetic frame 9 can be inserted into rectangular edge slot 6, so that rectangular magnetic frame 9 and filter plate 5 are magnetically attracted to limit and fix filter screen 8, and rectangular magnetic frame 9 can be hidden in the inside of rectangular edge slot 6, so that filter screen 8 can be completely attached to filter plate 5, avoiding the existence of gap to affect the complete filtering effect of flue gas.

[0035] The inside of filter screen 8 is hollow, so that flue gas can be filtered through the front and back of filter screen 8, and wave-shaped filter screen 10 is fixedly connected to the inside of filter screen 8, the wave-shaped structure of wave-shaped filter screen 10 can increase the filtering area of filter screen 8, and further improve the filtering effect of flue gas.

[0036] Side plates 11 are fixedly connected to both the left and right surfaces of the filter screen 8. When the side plates 11 move, they can drive the filter screen 8 to move synchronously. A handle 12 is fixedly connected to the front surface of the side plate 11. Users can pull the side plate 11 and the filter screen 8 by holding the handle 12, which makes it easy to quickly disassemble the filter screen 8.

[0037] Reference Figure 2 - Figure 3 The bottom surface of the air inlet 4 has a slot 13, and the top surface of the air inlet 4 has a groove 14. A plug 15 is fixedly connected to the bottom surface of the filter plate 5. The size of the plug 15 matches the size of the slot 13. The width of the slot 13 is greater than the plug 15. When installing the filter plate 5, the plug 15 can be inserted into the slot 13 first. Because the width of the slot 13 is greater than the plug 15, the filter plate 5 can rotate the plug 15 inside the air inlet 4, allowing the filter plate 5 to quickly enter the air inlet 4 and be initially positioned with the cooperation of the slot 13 and the plug 15. A flexible bracket 16 is fixedly connected to the top of the filter plate 5. The flexible bracket 16 engages with the inside of the groove 14. The flexible bracket 16 has a V-shaped structure. A locking block is fixedly connected to the upper surface of the filter plate 6. The elastic locking bracket 16 can be squeezed and compressed. When the filter plate 5 enters the air inlet 4, the elastic locking bracket 16 can be pinched to deform the elastic locking bracket 16 and drive the locking block to move down, so as to avoid affecting the installation of the filter plate 5. When the filter plate 5 enters the air inlet 4, the elastic locking bracket 16 can be released to allow the elastic locking bracket 16 to automatically recover its deformation and drive the locking block to move up, so that the elastic locking bracket 16 is engaged with the inside of the slot 14, further limiting the filter plate 5 and keeping the filter plate 5 stable during use. When the filter plate 5 needs to be disassembled and cleaned, simply pinch the elastic locking bracket 16 to release the engagement with the inside of the slot 14, rotate the filter plate 5 forward and lift it up to remove the filter plate 5. The operation is simple.

[0038] Working principle: through the cooperation of the filter screen 8, the wave-shaped filter screen 10 and the filter plate 5, the smoke inhaled into the frame 1 can be filtered, so that the oil and solid particles are separated from the air. After the extractor hood is used for a long time, the filter screen 8 needs to be disassembled and cleaned. If the solidified oil is adhered to the connection position between the edge of the filter screen 8 and the front surface of the filter plate 5, the filter screen 8 cannot be disassembled. The electric heating wire group 7 is electrified to generate heat, so that the oil is softened. When the filter screen 8 is disassembled, the filter screen 8 does not need to be pulled hard. Then the filter screen 8 can be pulled by the handle 12, so that the rectangular magnetic frame 9 leaves the inside of the rectangular side slot 6, and the disassembly is completed. The operation is simple. When the filter plate 5 needs to be disassembled and cleaned, the elastic clamping frame 16 is directly pinched, the clamping in the clamping slot 14 is released, the filter plate 5 is rotated forward and lifted, and the filter plate 5 can be disassembled.

[0039] Finally, it should be noted that: the above only for the preferred embodiments of the utility model, and does not limit the utility model, although the utility model is described in detail with reference to the foregoing embodiments, for the person skilled in the art, it still can modify the technical scheme recorded in the foregoing each embodiment, or equivalent replacement to part of technical features, any modification, equivalent replacement, improvement etc. within the spirit and principles of the utility model, should be included in the protection scope of the utility model.
