In the specific embodiment, the waterproof structure of the motor is applicable to any type of motor, and by way of example, the waterproof structure may be applicable to a rotating motor, that is, a motor in which an output shaft of the motor can relatively rotate with respect to a housing of the motor; the waterproof structure can also be applied to a linear motor, namely, the motor with the output shaft capable of performing linear reciprocating motion relative to the shell of the motor. Meanwhile, the motor can be suitable for any electrical equipment, for example, the motor can be suitable for a water pump, and the waterproof structure of the motor can reduce the possibility that pumped water flow enters the motor; for example, the motor may be applied to an air conditioner, and the waterproof structure of the motor may reduce the possibility that water vapor in the air may condense on the surface of the motor shaft and flow into the motor in the axial direction of the motor shaft. For convenience of description, the waterproof structure of the motor will be described below by way of example, in which the waterproof structure is applied to a rotating electric machine, and the motor is applied to an air conditioner. The type of the motor and the type of the motor equipment used by the motor do not affect the waterproof structure of the motor.

In some embodiments, as shown in fig. 1, the waterproof structure 1 of the motor includes: a motor cover 10 and a first blocking member 20. The motor cover 10 forms an accommodation cavity 11 for accommodating a body 2 of the motor, which body 2 of the motor may be, for example, a stator of the motor and a rotor of the motor. The motor cover 10 is provided with a through hole 12 communicated with the accommodating cavity 11, and a shaft body 3 connected to the motor of the body 2 penetrates through the through hole 12. Specifically, a part of the shaft body 3 is located in the accommodating cavity 11, is connected with the rotor of the body 2, and rotates around the axis of the shaft body in the length direction under the driving of the rotor; the other part of axis body 3 passes through-hole 12 and stretches out and hold chamber 11 to be connected with the part that needs to drive, thereby it is rotatory to drive the part that needs to drive.
