To sum up, the two-stage diagonal flow fan of 2 upper end of support frame can be mounted on by mounting plate 1 make when in use by user
Position then starts the two-stage diagonal flow fan, and the driving motor 5 for keeping it internal drives the twisted aerofoil leaf on transmission shaft 6
Piece 7 is rotated, and drives air to be flowed by the twisted aerofoil blades 7 of rotation, the air of two-stage diagonal flow fan blowout
It can be introduced into the carrying threaded barrel 92 in connecting rod 91, make it through the pore filter screen inside carrying threaded barrel 92
Dust in 94 pairs of air carries out preliminary purification, by activated charcoal strainer 96, HEPA filter screen 97 to the dust, different in air
The impurity such as taste carry out deep purifying, because long-time is using can make pore filter screen 94, activated charcoal strainer 96, HEPA filter screen 97
Purifying property decline, so user can catch rotating block 95 carry out rotation drive connection screw thread ring 93 rotate, make
Pore filter screen 94, activated charcoal strainer 96, HEPA filter screen 97 inside its connection screw thread ring 93 can be detached from carrying screw thread
The inside of cylinder 92, then to pore filter screen 94, activated charcoal strainer 96, the HEPA filter screen 97 inside connection screw thread ring 93
It is replaced to guarantee that its purifying property will not decline, the air being then cleaned can be discharged by guiding device 8, arranged
User can rotate limitation nut 89 when out, then stir the deflector 812 in limitation threaded post 88 up and down, make it through and lead
Flowing plate 812 controls the up and down direction for the wind that blower is blown out, and fixed pin 86 can also be pulled out from the inside of location hole 85
Out, it then catches bolster stake 87 to rotate 90 degree, enables deflector 812 on its adjusting frame 84 in bearing groove 810 from water
Placing flat becomes being disposed vertically, and then deflector 812 is stirred in left and right, and the left and right directions for the wind that can be blown out to blower is controlled
System is to be connected by swivel becket 83, rotation slot 82 with connection ring 81 because adjusting frame 84, so adjusting frame 84 can be into
Row rotation, such as when using the two-stage diagonal flow fan on rainy day, user needs that pull plate 107 is caught to pull outward, makes it
The extension plate 105 of 106 rear end of connecting column can utilize the sliding capability between connection sliding slot 103, connection sliding block 104 from link slot
It is pulled out in 102, allows it to block using extension plate 105 and protective plate 101 to the air inlet of blower, because of protective plate 101
It is to be connected by link block 108 with the two-stage diagonal flow fan, so protective plate 101 will not be oblique with two-stage in use
Flow fan mutually separates, because the two-stage diagonal flow fan use for a long time can generate dust, so user needs to the two-stage oblique flow
Dust in blower is cleared up, and in cleaning, user can rotate fixture nut 37, enables its fixing bolt 36 from circle
The inside of shape through-hole 35 is extracted, and upper half fixed plate 34 is then caught to be lifted up, and so that its upper plate guard box body 33 is utilized and is turned
Rotating property and lower half the protection cabinet 31 of dynamic circuit connector page 38 separately expose the component inside two-stage diagonal flow fan, and then user is
Dust on the component of exposing can be cleared up, it is more practical.
