Further, the indoor wind deflector that is also provided with of described fan blade, described wind deflector is between fan blade and air inlet.
Further, described wind deflector and fan blade are arranged side by side, and the middle part of described wind deflector is provided with a horn-like air guide hole, and the small end of this horn-like air guide hole, near described fan blade, is held away from described fan blade greatly.
Further, described bevel gear set comprises bevel gear, pinion and gear wheel, and described bevel gear is meshed with the terminal teeth of rotor axis of electric, and described pinion and bevel gear coaxially arrange, and described gear wheel is arranged on output shaft and with pinion and is meshed.
Further, described pinion and gear wheel are roller gear.
Further, described fan blade is centrifugal fan, is provided with 10～20, is preferably 15.
Further, described fan blade chamber is vortex housing shape.
Further, described sweep-up pipe is flexible pipe.
Further, described output shaft is perpendicular to rotor axis of electric.
Compared with prior art, the utlity model has following advantage:
First, there is self-dust-suction function, in the time of polishing, by the dust exhaust apparatus carrying, carry out dust suction, without increasing in addition dust catcher, both saved cost, brought many convenience to again workman's operation.
Secondly, simple in structure, rationally distributed, same motor had both driven polishing to stick to the pan work, drove again fan blade work, and while driving fan blade, had cancelled gear transmission structure.
Moreover, optimize the design of whole dust suction conducting, and increased wind deflector, pick-up performance is significantly improved, the reliability of work effectively improves.
Accompanying drawing explanation
Fig. 1 is the structural representation of the utility model long handle sander, and in figure, arrow represents dust suction trend.
Fig. 2 is the B-B cutaway view of Fig. 1.
The specific embodiment
The embodiment providing below in conjunction with accompanying drawing is further described the utility model.
As depicted in figs. 1 and 2, a kind of long handle sander that carries dust exhaust apparatus, comprises motor 1, rotor axis of electric 2, bevel gear set 3, output shaft 4, sticks to the pan 5, disk 6, hand-held long handle 7 and front fork 8.Wherein, rotor axis of electric 2 is in transmission connection through bevel gear set 3 and output shaft 4, and output shaft 4 is arranged on disk 6, sticks to the pan 5 and is located in disk 6 and is fixed on output shaft 4, and hand-held long handle 7 front ends are connected with disk 6 by front fork 8.Stick to the pan 5 and be provided with air suction opening 51, disk 6 is provided with dust absorption passage 61, fan blade 9 is installed on rotor axis of electric 2, fan blade 9 is installed with in an airtight fan blade chamber 10, fan blade chamber 10 has the air inlet 101 being communicated with the dust absorption passage 61 of disk 6, fan blade chamber 10 also has air outlet 102, and this air outlet 102 is connected with the dirt passage that goes out of hand-held long handle 7 through a sweep-up pipe 11.
