As shown in Figure 12 to Figure 16, blower fan apparatus 30 is used for producing and guiding air-flow；Specifically, blower fan apparatus 30 includes motor 31, main fan 32 and air-duct apparatus 33.
Motor 31 drives main fan 32 to rotate around axis 301, and main fan 32 can produce air-flow when rotating.Alternatively, main fan 32 is an aerofoil fan.
Air-duct apparatus 33 is formed with an air channel 330, and this air channel 330 is used for guiding main fan 32 and produces air-flow, and this air channel 330 is at least made up of one section of flexible pipe that can bend 332；And motor 31 and main fan 32 are arranged in air channel 330.
As a kind of embodiment, air-duct apparatus 33 includes blast pipe 331, flexible pipe 332 and discharge pipe 333, and wherein flexible pipe 332 is arranged between blast pipe 331 and discharge pipe 333, and flexible pipe 332 makes blast pipe 331 and the connection of discharge pipe 333 flexibility.Air channel 330 is the most at least made up of a blast pipe 331 and a discharge pipe 333, air channel 330 has an air inlet 331a being arranged at a blast pipe 331 and air outlet 333a being arranged at discharge pipe 333, and flexible pipe 332 is arranged between blast pipe 331 and discharge pipe 333.Air channel 330 ecto-entad at air inlet 331a gradually tapers up.Discharge pipe 333 includes that framework 333e, framework 333e are arranged on one end that discharge pipe 333 docks with flexible pipe 332 for supporting discharge pipe 333.
Main fan 32 is arranged in blast pipe 331, and motor 31 at least partly arranges in blast pipe 332, and motor 31 is supported in blast pipe 331.
Optionally, discharge pipe 333 includes multiple telescopic unit pipes 333b, 333c and 333d.User can make unit pipes 333b, 333c and 333d stretch by the mode of operation rotated or shrink.
Blast pipe 331 is additionally provided with casing 334, and casing 334 is formed with the motor cavity 334a for accommodating motor 31, this motor cavity 334a and is provided with two accent 334b, 334c being oppositely arranged and is used for allowing airflow into motor cavity 334a to cool down motor 31.
In order to realize more preferable cooling effect, motor 31 is also associated with an auxiliary blower 34, and this auxiliary blower 34 can be driven by motor 31 and then rotate generation air-flow.According to the pressure feature in air channel 330, auxiliary blower 34 produces the air-flow contrary with main fan 32 when rotating, and this flow direction carrying out air-flow inside and outside in motor cavity 334a is contrary, more contributes to the cooling to motor.
As a kind of concrete scheme, the pivot center 302 of auxiliary blower 34 and the shaft axis 301 of main fan 32 are on same straight line.
Additionally, the front end 334d of casing 334 stretches out to the direction of flexible pipe 332, and the outside of casing 334 has streamlined contour and forward end 334d gradually tapers up, the outside of casing 334 has the effect of water conservancy diversion, it can strengthen effective flowing of air-flow, especially guiding the air-flow of main fan 32 flabellum root, therefore casing 334 front end is stretched out flexible pipe 332 and is not only effectively reduced the size of blast pipe 333 and allow users to more flexible swing, and the air-flow also making air outlet 333a is higher.
Optionally, blast pipe 331 and discharge pipe 333 all parts are surrounded by flexible pipe 332.
In order to ensure that the reliability connected the most does not reduces the flexible angle of flexible pipe 332 simultaneously, blast pipe 331 is the length when flexible pipe 332 extend naturally with size A of software 332 lap and length B(of flexible pipe 332) ratio be more than or equal to 0.2 and be less than 0.5.Additionally, in order to not hinder flexible pipe 332 to bend while realizing good effect, casing 334 front end 334d stretches out the ratio of length C of blast pipe 332 and flexible pipe 332 free bend part (go out when flexible pipe 332 extend naturally the part being coated on blast pipe 331 and discharge pipe 333 beyond length D) and is more than or equal to 0.1 and is less than or equal to 0.3.
It addition, in order to keep discharge pipe 333 in the structural strength with flexible pipe 332 junction, make securing member 51 support discharge pipe 333 when banding flexible pipe 332 and make it not have bigger deformation.
Scheme further, blower fan system 100 also includes handle 60, and user can operate blower fan apparatus 30 by handle 60.
In order to allow users to more directly effective manipulation discharge pipe 333, handle 60 is connected to discharge pipe 333, makes user drive discharge pipe 333 when pivotal handle 60.Specifically, operating handle 60 can slide relative to discharge pipe 333, to adapt to the user of different brachium.Optionally, handle 60 is provided with operating trigger 61 and controls the operation of motor 31 for user, in order to ensure to use safety handle 60 to be additionally provided with security triggers 62, when user does not presses security triggers 62, user can not start motor 31 by operating trigger 61, and in order to make user be convenient to use the pattern that wind-force is stronger, handle 60 is additionally provided with strength button 63, once user presses strength button 63, and the mode activated main fan 32 with peak power is rotated by motor 31.Specifically, operating trigger 61 is positioned at security triggers 62 and handles the both sides that spanner 60 is relative.User can be with one-handed performance operating trigger 61 and security triggers 62, when user is hold by one hand handle 60, it is also possible to press pressure force button 63 by finger.
In order to allow users to suitably adjust steering-hold, handle 60 is configured to rotate relative to flexible pipe 332, makes handle 60 be in different position relatively, user so can be made to handle discharge pipe 333 with the most comfortable posture.
