Specific embodiment
The following will be combined with the drawings in the embodiments of the present invention, carries out the technical scheme in the embodiment of the utility model
Clearly and completely describe, it is clear that the described embodiments are only a part of the embodiments of the utility model, rather than whole
Embodiment.
Referring to Fig.1-3, a kind of micromotor with waterproof construction, including electric machine casing 1, rotor 3 and pedestal 8, motor
The inner rotation of shell 1 is connected with rotor 3, is provided with sponge card slot 2 at the inner wall and 3 link position of rotor of electric machine casing 1, sea
The inside of continuous card slot 2 is filled with sponge 4, and the outer wall of electric machine casing 1 offers air hole 6, and the viscous of air hole 6 has PTFE
Film 5, the tail end of electric machine casing 1, which is connected together, pedestal 8, and rubber pad 7 is connected between pedestal 8 and electric machine casing 1, pedestal 8
Two sides offer slot electrode 82, and the inside of slot electrode 82 is fixed with electrode slice 83, and the end of the corresponding pedestal 8 of rotor 3 is fixed with
