The right end face of the baffle 7 abuts against the left end face of the protrusion 14, thereby limiting the leftward movement of the motor mounting seat 1, and further improving the installation stability of the motor mounting seat 1 and the base 4.

[0056] In this embodiment, the baffle 7 abuts against the left end face of the protrusion 14 of the motor mount 1, and the stop portion 6 abuts against the right end face of the motor mount 1, thereby further limiting the movement of the motor mount 1 in the left and right directions, preventing the motor mount 1 from being offset, and further preventing air from passing through the connection between the motor mount 1 and the base 4, thereby reducing noise.
