Description
Technical field
This utility model relates to the roof blower fan of a kind of convenient dismounting.
Background technology
Current roof blower fan is generally used for indoor air is imported to outdoor, and the blade also used is plate blade, and air output is limited, it addition, the dynamics that its support supports is the least, during as used bigger blade, the most current support is the most applicable.
Utility model content
The purpose of this utility model is to provide the roof blower fan of a kind of convenient dismounting, solves how to improve the technical problem of the support degree of the exhaust air rate of roof blower fan and support.
The roof blower fan of convenient dismounting, including blast cap, airduct, blower fan, support, fire resisting damper, anti-bird door；Airduct is fixed on below blast cap；Anti-bird door, blower fan, fire resisting damper are arranged in inside airduct from top to bottom；Support is fixed between blower fan and airduct；Anti-bird door and fire resisting damper are network structure；Blower fan, including motor, wind wheel；Wind wheel includes the wheel hub of taper, multiple blade, multiple wind guide vane；Leaf positional distribution is on wheel hub, and wind guide vane is fixed on wheel hub and is between the middle and lower part of each two adjacent blades, described blade interior hollow；Support one end is tabular, and this tabular is fixed together with airduct laminating, and the other end is arc, and this arc is fixed together with motor laminating.
Being additionally provided with an overheated mechanism of motor for preventing in the roof blower fan of described convenient dismounting, this mechanism includes a motor protecting cover, blast pipe, discharge pipe, cooling fan；Motor is wrapped in motor protecting cover, is filled with heat-preservation cotton in this motor protecting cover；Cooling fan is fixed on the rear side of motor, blast pipe and discharge pipe distribution and is fixed on the both sides of motor protecting cover, and wherein one end of blast pipe is towards cooling fan.
The beneficial effects of the utility model are: owing to being mounted with that on wheel hub air is done work by wind guide vane, wind guide vane, thus can reduce the eddy current between adjacent blades, wind guide vane is the most, and eddy current is the least, and air output is the biggest；Owing to being provided with support, this support uses quill, and movable insertion is fixed in sleeve, so makes the length of whole support to be adjusted as required；Prevent overheated mechanism by arranging blower fan, so make motor cool down in running, thus protect motor.

Detailed description of the invention
Refer to Fig. 1 to Fig. 4, the roof blower fan of the convenient dismounting in figure, including 6, overheated mechanism of motor for preventing 7 of 5, anti-bird door of 2, blower fan of 1, airduct of a blast cap, 4, fire resisting damper of 3, support.
Blast cap 1, airduct 2, fire resisting damper 5, anti-bird door 6 are common structure.Airduct 2 is fixed on below blast cap 1；It is internal that anti-bird door 6, blower fan 2, fire resisting damper 5 are arranged in airduct 2 from top to bottom；Anti-bird door 6 and fire resisting damper 5 are network structure.Blower fan 3, including motor 31, wind wheel 32；Motor 31 is common motor, and wind wheel 32 includes the wheel hub 321 of a taper, multiple blade 322, multiple wind guide vane 323；Blade 322 is evenly distributed on wheel hub 321, and between the middle and lower part being fixed on wheel hub 321 and being in each two adjacent blades 323 that wind guide vane 323 tilts, blade 323 inner hollow plays the effect of sound insulation de-noising.
The overheated mechanism of motor for preventing 7 includes a motor protecting cover 71, blast pipe 72, discharge pipe 73, cooling fan 74；Motor 31 is wrapped in motor protecting cover 71, is filled with heat-preservation cotton in this motor protecting cover 71；Being fixed with support 4 between motor protecting cover 71 and airduct 2, this support 4 one end is tabular, and this tabular is fixed together with airduct 2 laminating, and the other end is arc, and this arc is fixed together with motor protecting cover 71 laminating.Cooling fan 74 is fixed on the rear side of motor 31, blast pipe 72 and discharge pipe 73 distribution and is fixed on the both sides of motor protecting cover 71, and wherein one end of blast pipe 72 is towards cooling fan 74.So when cooling down fan 74 and rotating, in the external world just can be cooled down air driven motor protecting cover 71 by it and discharge from discharge pipe 73.
