Specific embodiment

The utility model is described further with reference to the accompanying drawing.

A kind of brushed DC motor, as shown in Figures 1 to 4, including base 1, stator core 2 and rotor 3, the stator iron Core 2 is central column, and the rotor 3 is embedded into the stator core 2, and the base 1 is central column, and lower end is fixed with stabilizer blade 11, the base 1 is set in 2 outer surface of stator core；The 1 pars intramuralis ring of base circumferentially offers snakelike water of crossing and leads to Road 4,1 bottom end of base are equipped with the water inlet pipe 12 and outlet pipe 13 being connected respectively with 4 head end of water passage and end, It is fixed with water storage box 5 on the stabilizer blade 11, is equipped with the micro pump 6 being connected with the water inlet pipe 12, institute in the water storage box 5 The water outlet for stating outlet pipe 13 is connected to water storage box 5, and 5 bottom of water storage box is equipped with dewatering outlet, and side is equipped with water storage mouth.Using machine In 1 wall of seat in 1 bottom water storage box 5 of snakelike water passage 4 and base micro pump 6 combination, on the one hand can will be in water storage box 5 Water is pumped into water passage 4 and recycles it in water passage 4 and water storage box 5, thus production when reducing motor work Raw high temperature；On the other hand, after being fixed on the water storage box 5 plus water of 1 bottom of base, increase motor weight, can reduce motor work Make the vibration generated.

When work, by the built-in full water of water storage box 5, then starts micro pump 6, the water in water storage box 5 was pumped into water It in channel 4 and recycles it in water passage 4 and water storage box 5, operates the high temperature generated to reach reduction motor Purpose.

In the present embodiment, several axial convex stupefied 14 are fixed on the inner wall of the base 1, the stator core 2 Offer several axial grooves 21 to match with described convex stupefied 14 on outer wall, the stator core 2 by convex stupefied 14 with it is recessed The fixation between base 1 is realized in the cooperation of slot 21.Specifically, when base 1 is combined with stator core 2, by groove 21 with it is convex After stupefied 14 are corresponding in turn to, stator core 2 is embedded into base 1.Due to convex stupefied 14 and the cooperation of groove 21, so that machine It assembled between seat 1 and stator core 2, dismantle more convenient, and relatively passed since the combination between convex stupefied 14 and groove 21 is fixed Contact area is bigger when the bolt and screw hole of system combine fixed, to make to combine between 1 inner wall of base and stator core 2, be bonded It is even closer, it reduces and shakes space, the noise and smaller to the loss of parts thereof for generating motor work, but also machine Faster, more conducively stator core 2 cools down temperature conduction between seat 1 and stator core 2.

In the present embodiment, convex stupefied 14 top is equipped with the baffle 141 for preventing stator core 2 from being detached from out of base 1, The baffle 141 is hinged on convex stupefied 14 top by shaft 142, and the shaft 142 is embedded in and is fixed on convex stupefied 14.When After base 1 and stator core 2 assemble, rotates baffle 141 and it is made to be blocked in the top of groove 21, to make stator core 2 can not detach out of base 1.

In the present embodiment, the shaft 142 is arranged with the torsional spring for making baffle 141 playback with 141 hinged place of baffle 1421.After stator core 2 is embedded into base 1, baffle 141 under the active force of torsional spring 1421 can automatic homing stop to fixed The top of sub- iron core 2, when removing stator core 2 out of base 1, moves gear to prevent it from detaching out of base 1 Piece 141 disengages it from the blocking range to 2 top of stator core, then extracts stator core 2 out of base 2 out.

In the present embodiment, the top of the base 1 is equipped with handle 15, the convenient movement to this motor.
