[0030] The two mounting seats 16 are symmetrically fixedly connected to the two sides of the purification box 12, the two limiting seats 14 are symmetrically fixedly connected to the upper surface of the fume inlet hood 11, and a card slot 17 is opened inside the limiting seat 14. The mesh plate 13 is fixedly connected to the upper surface of the purification box 12 by screws, the activated carbon box 22 is slidably connected to the inner side wall of the purification box 12, the lower surface of the purification cotton 23 is attached to the inner bottom wall of the purification box 12, the sealing ring 24 is fixedly connected to the lower surface of the purification box 12, the sliding seat 18 is slidably connected to the inner side wall of the mounting seat 16, and a card block 19 is fixedly connected to one side of the sliding seat 18. The spring 21 is sleeved on the outer side wall of the guide column 20, and the sliding seat 18 is slidably connected to the outer side walls of the two guide columns 20.

[0031] In one embodiment, the lower surface of the mesh plate 13 is attached to the upper surface of the activated carbon box 22, the lower surface of the activated carbon box 22 is attached to the upper surface of the purification cotton 23, the mounting seat 16 is slidably connected to the inner wall of the limiting seat 14, the guide column 20 is fixedly connected to one side of the inner wall of the mounting seat 16, the two ends of the spring 21 are respectively fixedly connected to the sliding seat 18 and the mounting seat 16, the block 19 is slidably connected to the inner wall of the slot 17, the sliding seat 18 is pushed by the spring 21, and the sliding seat 18 drives the block 19, so that the block 19 can be clamped in the slot 17, thereby limiting the position of the purification box 12.

[0032] In one embodiment, the lower surface of the purification box 12 is attached to the upper surface of the fume intake hood 11 through a sealing ring 24, two handles 25 are installed on the top of the lower surface of the fume intake hood 11, and a magnetic block 15 is fixedly connected to the top of the upper surface of the fume intake hood 11. By providing a sealing ring 24 between the purification box 12 and the fume intake hood 11, fume leakage can be avoided, thereby ensuring the purification effect.

[0033] In one embodiment, a main body assembly 301 is installed outside the oil fume intake hood 11, and the main body assembly 301 includes a housing 31, a guide housing 32 and a silent fan 35;

[0034] The guide shell 32 is fixedly connected to the upper surface of the casing 31 and communicated with the casing 31 . The silent fan 35 is installed inside the guide shell 32 . Under the guidance of the silent fan 35 , the fumes in the kitchen can be sucked into the casing 31 .

The position of the oil fume intake hood 11 can be limited by the magnetic block 15. When the magnetic block 15 is separated from the casing 31, the oil fume intake hood 11 can be rotated to disassemble the purification box 12.

[0037] When the utility model is working: the silent fan 35 is working, the oil smoke in the kitchen flows into the interior of the casing 31 through the air inlet hole on the oil smoke air inlet hood 11, the oil smoke first contacts with the purification cotton 23, and then contacts with the activated carbon in the activated carbon box 22, and the oil smoke can be purified by the purification cotton 23 and the activated carbon. The grease, particulate matter and other harmful substances in the oil smoke can be purified, and the purified air flows into the guide shell 32 under the guidance of the silent fan 35, and then discharged. The temperature in the kitchen is monitored in real time by the temperature sensor 33.

[0038] After the range hood has been working for a while, it is necessary to replace the purification cotton 23 and the activated carbon in the activated carbon box 22. The oil fume intake hood 11 is pulled by the handle 25 to separate the magnetic block 15 from the casing 31, and then the oil fume intake hood 11 is turned over to expose the purification box 12. The blocks 19 on both sides are pressed to disengage the blocks 19 from the slots 17, and then the purification box 12 is pulled to separate the purification box 12 from the oil fume intake hood 11. The lower mesh plate 13 can be removed to take out the activated carbon box 22 and the purification cotton 23 for replacement; after the replacement is completed, the mounting seat 16 is inserted into the limit seat 14. Under the push of the spring 21, the block 19 is automatically stuck in the slot 17. The purification box 12 is installed, and the oil fume intake hood 11 is turned over to make the magnetic block 15 engage with the casing 31, so that the range hood can work normally.
