Specific embodiment
Below by the technical scheme in the utility model embodiment is clearly and completely described, it is clear that described
Embodiment is only the part of the embodiment of the utility model, instead of all the embodiments.Based on the implementation in the utility model
Example, all other embodiment that those of ordinary skill in the art are obtained without making creative work belong to
The range of the utility model protection.
Referring to Fig. 1, a kind of power head, including casing 1, the motor 2 being installed in casing 1, gear-driven assembly 3 and beat
Toothed burclover 4, motor 2 drive moving head 4 to work by gear-driven assembly 3, have air intake 5 and outlet air end 6, casing 1 on casing 1
It is interior equipped with the air inlet duct 7 connected with air intake 5 and the exhaust passage 8 connected with outlet air end 6, the rotation of motor 1 make cooling wind from into
By being discharged after flowing to outlet air end 6 from exhaust passage 8 again after the inflow motor of air inlet duct 7 after entering in wind end 5, air inlet duct 7 and electricity
Machine 2 is connected and is entered the wind at the two of motor 2.
In addition, air inlet duct 7 includes the first air inlet duct 71 and the second air inlet duct 72, the first air inlet duct 71 and the second air inlet duct 72
Motor 2 is connected to enter the wind at the two of motor 2.
In addition, the top and bottom of motor 2 are connected with the first air inlet duct 71 and the second air inlet duct 72 from the upper of motor 2 respectively
It enters the wind, is connected with exhaust passage 8 at the fan blade of motor 2 for outlet air at end and lower end two.
In addition, air intake 5 is located at the upper end of casing, outlet air end 6 is located at the lower end of casing 1.
In addition, moving head 4 is equipped with centrifugation blade 41, centrifugation blade 41 is located at outlet air end 6, and the rotation of moving head 4 drives
