The technical scheme in the invention for solving the above technical problem is: a kind of ducting system with fume purifying function, including air channel, motor and impeller；Air channel is provided with air inlet and air outlet；Motor is arranged on air channel；Impeller is connected with the rotating shaft of motor, and it communicates with air inlet and the air outlet in air channel；It is characterized in that: also include deflector；Deflector is fixed on air channel, and is positioned at the air inlet in air channel, is covered by the air inlet in air channel；Deflector includes fixing plate and grid；Fixing plate is fixed on air channel；Grid is fixed on fixing plate, and grid is lamellar；Grid is multiple, forms runner between adjacent two grids；Runner one end is air intake, and the other end is outlet air end, and outlet air end communicates with the air inlet in air channel；
The structure of described grid is at least the one in following three kinds of structures:
(1), adjacent two grids be arranged in parallel, and the axis parallel of the middle section of grid and impeller；
(2), adjacent two grids be arranged in parallel, and the axis of the middle section of grid and impeller forms an angle α, 0 ° of < α < 60 °；
(3), shape has angle β between adjacent two grids, 0 ° of < β < 60 °；Grid forms divergent shape structure.
Fixing plate described in the utility model is annular.
The angle of α described in the utility model is one in 10 °, 20 °, 30 °, 40 °, 50 °.
The angle of β described in the utility model is one in 10 °, 20 °, 30 °, 40 °, 50 °.
This utility model is compared with prior art, have the following advantages and effect: produce more molecular collision chances by the guide functions of grid, and make soot gas discharge after entering air channel in order, be greatly improved grease separating degree, meanwhile, the noise of range hood also can reduce further.

Detailed description of the invention
Below in conjunction with accompanying drawing and by embodiment, the utility model is described in further detail, and following example are that this utility model is not limited to following example to explanation of the present utility model.
Referring to Fig. 1～Fig. 8, this utility model embodiment includes air channel 1, motor 2, impeller 3 and deflector 4.
Air channel 1 is provided with air inlet and air outlet.
Motor 2 is arranged on air channel 1.
Impeller 3 is connected with the rotating shaft of motor 2, and it communicates with air inlet and the air outlet in air channel 1.
Deflector 4 includes fixing plate 5 and grid 6；Deflector 4 is fixed on air channel 1, and is positioned at the air inlet in air channel 1, is covered by the air inlet in air channel 1.
Fixing plate 5 is annular, is fixed on air channel 1.
Grid 6 is fixed on fixing plate 5.Grid 6 is multiple, forms runner 7 between adjacent two grids 6；Runner 7 one end is air intake, for inspiration soot gas；Runner 7 other end is outlet air end, and outlet air end communicates with the air inlet in air channel 1.Grid 6 is lamellar, produces the effect of water conservancy diversion.
Motor 2 impeller 3 forms negative pressure after rotating, and the air intake of runner 7 accepts the soot gas flowing because negative pressure produces, and produces molecular collision and cutting out partial smoke particle through grid 6 when soot gas flows in runner 7, and remaining gas is discharged through air channel 1.
Embodiment 1: adjacent two grids 6 are in arranged in parallel, and the axis parallel of the middle section of grid 6 and impeller 3.Soot gas flows through in the process of runner 7 due to suction function, and big particle diameter soot particles can depend on grid 6 on travel path, thus only having fraction oil smoke to enter impeller 3 and air channel 1.Along with the oil smoke on grid 6 gathers, finally because of action of gravity landing to the oil collector sump tank in air channel 1.
Embodiment 2: adjacent two grids 6 are in arranged in parallel, and the axis of the middle section of grid 6 and impeller 3 forms an angle α, 0 ° of < α < 60 °.On the basis of embodiment 1, increase the air-flow angle of attack, increase soot particles collision dynamics and probability, improve grease separating degree further.The angle of α is one in 10 °, 20 °, 30 °, 40 °, 50 °.
Embodiment 3: between adjacent two grids 6, shape has angle β, 0 ° of < β < 60 °, grid 6 forms divergent shape structure.The divergent shape structure of grid 6, adapts to the gas field feature that lower flow passage blast is big, upper flow passage blast is little, and air inlet is more uniform so that soot particles adsorbance on grid 6 is average.The angle of β is one in 10 °, 20 °, 30 °, 40 °, 50 °.
Furthermore, it is necessary to illustrate, the specific embodiment described in this specification, the shape of its parts and components, be named title etc. can be different, and the above content described in this specification is only to this utility model structure example explanation.
