Specific implementation mode

Present embodiment is designed to provide a kind of active carbon filtering device, can effectively improve activated carbon Adsorption efficiency.The purpose of present embodiment, which also resides in, provides a kind of air purification including above-mentioned active carbon filtering device Device.

Hereinafter, being illustrated to embodiment with reference to attached drawing.In addition, embodiments illustrated below is not to recorded in claim Utility model content rise any restriction effect.In addition, the full content of the composition represented by following example is not limited to conduct Necessary to the solution of utility model recorded in claim.

- Fig. 6, active carbon filtering device provided in this embodiment, including multiple ribs are please referred to Fig.4, multiple ribs are divided into At least two groups, each group rib extending direction is different, the multiple units that can the be surrounded in this way, rib extended in different directions interlocks Lattice 11.

Cell 11 constitutes ventilating duct, and cell 11 is internally provided with activated carbon 13, along air inlet direction, cell 11 Front and rear sides are designed with screen cloth 12, and 12 one side of screen cloth can stop that activated carbon 13 is blown out, and another aspect screen cloth 12 also can It plays a role in filtering.

In the present embodiment, there is gradually inclined rake 14 upward or downward along the bottom surface of air inlet direction, cell 11.

So set, in technical solution provided in this embodiment, by the way that the bottom surface of cell 11 is provided with rake 14, In the case that amounts of activated carbon in cell 11 is identical and 11 air intake passage area equation of cell, rake 14 can make 13 front face area of activated carbon obviously increases, and is obviously improved the contact area of activated carbon 13 and wind, improves activated carbon 13 and absorbs and filter Efficiency.
