Accompanying drawing illustrates:
Fig. 1 is structural representation of the present utility model;
Fig. 2 is partial enlarged drawing of the present utility model.
Detailed description of the invention:
Embodiment: embodiment, see as shown in Figure 1 to Figure 2, a kind of blower fan filtering device, comprise air inlet tube connector 10 and blast pipe 20, the lateral wall of the outlet air end of described air inlet tube connector 10 has adpting flange 11, the air intake of air inlet tube connector 10 is bolted with blast pipe 20, at least two filter screen devices 30 are inserted with in the front portion of blast pipe 20, activated carbon granule 70 is filled with in blast pipe cavity between two filter screen devices 30, the anterior sidewall of blast pipe 20 has multiple through hole 21 that is spirally connected, press closer bolt 22 to be screwed onto and to be spirally connected in through hole 21, the end pressing closer bolt 22 has limiting section 221, limiting section 221 stretches in blast pipe 20 shrinkage pool 31 that also sleeve has on the sidewall of the filter screen device 30 of correspondence,
The lower sidewalls that described blast pipe 20 is in the front portion of filter screen device 30 connects and has filtered tube connector 40, filtered on tube connector 40 and connected Object storing drum 50.
Further, described filter screen device 30 comprises annular fixed frame 32 and screen pack 33, the edge of screen pack 33 is bolted to connection on the madial wall of annular fixed frame 32, screen pack 33 covers the middle part opening of annular fixed frame 32, the lateral wall of annular fixed frame 32 has multiple shrinkage pool 34, and shrinkage pool 34 is corresponding with the through hole 21 that is spirally connected of blast pipe 20.
Further, the rear end face of the annular fixed frame 32 of the previous filter screen device 30 in described two filter screen devices 30 has multiple protruding post 35, the front end face of the annular fixed frame 32 of the filter screen device 30 at rear has multiple connecting hole 36, and protruding post 35 sleeve is in the connecting hole 36 of correspondence.
Further, described in press closer bolt 22 rearward end on there is hand-held rotation section 222, the lateral wall of blast pipe 20 is stretched out in hand-held rotation section 222.
Further, described blast pipe 20 is the bending tube of rectangular bending, the rear portion upwards vertically bending of blast pipe 20.
Operation principle: filtered by the screen pack 33 of two filter screen devices 30 and activated carbon granule 70 after wind is entered by the air inlet of blast pipe 20, enter again in blower fan, wherein, filtered by activated carbon granule 70, smell etc. in wind can be filtered, its filterability is better, and filtered by two screen packs 33, filter effect can be improved further, and excessively general being just blocked in the front portion of blast pipe 20 by the object after first screen pack 33 is also dropped in Object storing drum 50 by filtering tube connector 40, thus can ensureing to drop the material filtered, to affect annular on ground clean and tidy.
