The inner wall of the range hood host 1 is provided with a group of slide grooves 14 close to the L-shaped load-bearing rods 13. A push plate 15 extending into the L-shaped load-bearing rod 13 is slidably provided in the slide grooves 14. The push plate 15 is bolted to the L-shaped load-bearing rod 13. A support groove 20 is provided on the inner wall of the L-shaped load-bearing rod 13. The push plate 15 extends from one end of the slide groove 14 to the support groove 20. A plurality of shock absorbers 28 are evenly provided on the top surface of the push plate 15. A plurality of mounting bolts 29 that are connected to the shock absorbers 28 are penetrated through the L-shaped load-bearing rod 13.

[0026] Through the above structure, the filter frame 6 is first placed in the range hood main unit 1 from bottom to top, and then the push plate 15 is pushed to make it slide in the slide groove 14 into the support groove 20 until the push plate 15 is completely in the support groove 20. At this time, the push plate 15 is close to the inside of the L-shaped load-bearing rod 13, and then the mounting bolts 29 are used to penetrate the L-shaped load-bearing rod 13 and connect it to the shock absorber 28 to complete the installation operation of the filter frame 6.

The activated carbon filter 10 can be taken out of the annular groove 21 by rotating and removing the nut 26. After inspection and replacement, the activated carbon filter 10 is placed in the annular groove 21. At this time, the card plate 22 passes through the limiting hole 24 to penetrate the limiting rod 23, and the nut 26 is used to fit tightly against the card plate 22 under the action of the fixed thread groove 25 to complete the inspection operation of the activated carbon filter 10.

[0031] When the range hood is working, the fan wheel 5 rotates to draw the oil smoke into the filter frame 6. The filter frame 6 and the metal mesh 9 pre-filter the oil smoke to remove large particles and impurities in the air. The oil smoke then enters the activated carbon filter 10. The multiple activated carbon adsorption plates 11 in the activated carbon filter 10 adsorb most of the oil and impurities in the oil smoke, and then are discharged through the top of the range hood main body 1. The oily liquid automatically flows into the oil frame 7 for collection. The oil frame 7 is regularly rotated and removed from the connecting rod 16 for cleaning. After cleaning, it is installed by fitting the threaded protrusion 19 in the connecting sleeve 18 with the connecting thread groove 17 on the connecting rod 16.
