[0043] Please see attached Figure 1 -Attached Figure 8In a preferred embodiment, the collecting assembly includes: a turntable 24, which is rotatably mounted on the top of the collecting box 4, a circular groove 28 is provided at the center of the top of the turntable 24, a one-way bearing 29 is installed in the circular groove 28, a rotating shaft 30 is vertically fixedly installed at the center of the bottom of the disk 3, and the end surface of the rotating shaft 30 is fixedly installed inside the inner ring of the one-way bearing 29, a through feeding port is provided at the top of the collecting box 4, a baffle 31 is slidably provided at the top of the collecting box 4, and two extending shafts are horizontally fixedly installed on the side of the collecting box 4.

[0045] The working principle of the present invention is as follows: firstly, the furniture to be de-formaldehydeed is placed on the placement tray 10, and then the cabinet door is closed. It should be noted that the hopper 6 and the three troughs 15 are filled with activated carbon particles;

[0046] Then start the hot air blower 9 and the second motor, the second motor drives the placement tray 10 and the furniture placed thereon to rotate. It should be noted that a fixture for fixing the furniture is installed on the placement tray 10, the hot air blower 9 can circulate and heat the gas inside the cabinet 1, and the hot air is evenly ejected through the air outlet plate to evenly heat the rotating furniture, and the gas containing formaldehyde generated by the heating will be filtered through the activated carbon particles inside the trough 15 and then return to the inside of the cabinet 1, and the furniture can be heated and formaldehyde removed by the cycle in sequence;

[0047] After the activated carbon particles in the trough 15 have been used for a period of time, the first motor 14 is started to drive the belt 13 and the pulley to rotate forward. It should be noted that the first motor 14 is a forward and reverse motor and rotates 120 degrees each time. The rotation of the pulley drives the shaft and the disc 3 to rotate. The forward rotation of the disc 3 drives the three troughs 15 and the activated carbon and components inside thereof to rotate forward together. At this time, the disc 3 drives the rotating shaft 30 to rotate, and the rotating shaft 30 will not drive the rotating disc 24 to rotate through the one-way bearing 29. Due to the setting of the friction ring 8, the disc 3 also rotates when it rotates. The friction roller 16 will be driven to rotate while revolving, and the rotation of the friction roller 16 will drive the rotating rod 20 to rotate, and the rotation of the rotating rod 20 will drive the two bevel gears 19 to rotate, and the rotation of the two bevel gears 19 will drive the stirring rod 21 to rotate. The stirring rod 21 can stir the activated carbon particles inside the material tank 15. The turning can prevent a part of the activated carbon area from being exposed to pollutants for a long time, which is helpful to more evenly distribute the adsorption effect and prolong the use effect and time. The activated carbon particles inside the material tank 15 can be disturbed by reciprocating in sequence;

[0048] When the activated carbon particles in the trough 15 are saturated and need to be replaced, it is only necessary to drive the pulley to reverse, and the rotating shaft 30 will drive the turntable 24 to rotate through the one-way bearing 29, and the rotation of the turntable 24 will drive the annular groove 25 and the V-shaped groove 26 to rotate, and the rotation of the annular groove 25 and the V-shaped groove 26 will drive the sliding column 27 to move, and the movement of the sliding column 27 will drive the folding plate 23 to move, and the movement of the folding plate 23 will drive the baffle 31 to move, and the movement of the baffle 31 will first release the blockage of the discharge port, and then the activated carbon particles in the trough 15 moved to the discharge port will fall into the collection box 4, and then the baffle 31 will reset to block the discharge port again, and when the first motor 14 works again, the trough 15 after unloading will move to the bottom of the hopper 6, and the activated carbon particles in the hopper 6 will enter the trough 15, so that the activated carbon particles in the trough 15 have been replaced, and finally the first motor 14 is operated once again, and the replaced activated carbon particles can be used to adsorb formaldehyde;

[0049] In summary, two different methods can be selected to process the activated carbon particles according to the state of the activated carbon particles, thereby improving the use effect of the equipment.

[0050] In addition, it should be understood that although the present specification is described according to implementation modes, not every implementation mode contains only one independent technical solution. This description of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment may also be appropriately combined to form other implementation modes that can be understood by those skilled in the art.
