Detailed description of the invention

Below in conjunction with drawings and Examples, this utility model is further described.Description below It is to use the mode enumerated, but protection domain of the present utility model should not be limited to this.

The present embodiment is by motor 5, output connection dish 1, wind scooper 4 and impeller inducer 2 and peace Shelve journal stirrup 6 to constitute.

Motor 5 includes stator, rotor, upper end cover, bottom end cover, output shaft 3 and installing rack journal stirrup 6； Rotor installs in the stator, and upper end cover, bottom end cover are arranged on the two ends up and down of stator, installing rack journal stirrup 6 middle parts being arranged on stator；Output shaft 3 is installed in the rotor, and its lower end is installed in bottom end cover, Upper end passes upper end cover, becomes outfan.

It is provided with contiguous block, for the input with equipment even in the upside card of output connection dish 1 Connect, transmit power.

Impeller inducer 2 can be by several spiral type curved wind guide vanes being distributed on impeller disc The single impeller inducer that sheet is constituted；Can also be by being distributed on the downside of output connection dish 1 in card Article 8, (alternatively 2 or 3 or 4 or other quantity, this example is set to 8) spiral type Curved wind blade is constituted, and it is connected dish 1 with output and unites two into one body；It is arranged on this lower disc The supercentral shaft sleeve in face, is sleeved on the upper end of output shaft 3.

Wind scooper 4 is to be formed by the curling of wind-guiding sheets.

One end of wind-guiding sheets after wind scooper 4 launches, is provided with two dops 7, at the other end Portion has matched draw-in groove 11.The both sides in the middle part of wind-guiding sheets after wind scooper 4 launches, Have the journal stirrup mounting hole 8 for installing installing rack journal stirrup 6.Leading after wind scooper 4 launches The bottom of fan housing sheet, also has the wire installing hole 9 for disposing power lead-ining line.Meanwhile, leading Fan housing 4 launch after wind-guiding sheets following, also have the wire for installing power lead-ining line and install Notch 10, the inner that notch 10 installed by this wire is through with wire installing hole 9.

During installation, the journal stirrup mounting hole 8 of the wind-guiding sheets one end after first being launched by wind scooper 4 is inserted in peace Shelve one end of journal stirrup 6, then, wind-guiding sheets is crimped to installing rack journal stirrup around the periphery of motor 5 The other end of 6, and being inserted in corresponding journal stirrup mounting hole 8, meanwhile, by power lead-ining line by Wire is installed notch 10 and is incorporated in wire installing hole 9, thereafter, dop 7 is snapped in draw-in groove 11 In.Now, wind scooper 4 is fitted in the surface of motor 5 well, with motor 5 inside it Outside formed heat dissipation wind channel.In work process, the impeller inducer in card on the downside of output connection dish 1 2 rotate along with output shaft 3, produce convulsion, and cold air is drawn into by the lower end of wind scooper 4, passes through The heat dissipation wind channel that the inner side of wind scooper 4 and the outside of motor 5 are formed (includes between stator and rotor Space), flow to impeller inducer 2 and flow outwardly, thus, take away institute between stator and rotor The heat produced, reduces the temperature rise of motor 5.

Series excited machine with wind scooper of the present utility model, is suitable for and the household electrics such as domestic mixer Device supports the use.
