DETAILED DESCRIPTION OF THE EMBODIMENTS

[0027] For further illustrating the invention, experiments detailing a blower are described below. It should be noted that the following examples are intended to describe but not to limit the invention.

[0028] As shown in FIGS. 2, 3, 4, 5 and 6, a blower comprises a volute 1, a motor 2 and a blower wheel 3. The motor 2 is disposed on the volute 1, and comprises a spindle 11, a rotor assembly 12, a stator assembly 13, a motor housing 14, a front-end cover 15, a rear-end cover 16 and a capacitor 17. The rotor assembly 12 is disposed on the spindle 11. The stator assembly 13 and the motor housing 14 are integrated and sleeved on the rotor assembly 12. The front-end cover 15 and the rear-end cover 16 are disposed on two ends of the motor housing 14, respectively. The two ends of the spindle 11 support the bearing of the front-end cover 15 and the bearing of the rear-end cover 16 respectively. The front end of the spindle 11 extends into the volute 1 and is connected to the blower wheel 3. The box 4 is disposed on the rear-end cover 16.

[0029] The capacitor 17 is disposed in the cavity formed by the box 4 and the rear-end cover 16. The box 4 comprises a cavity part 41 and a turnup part 42 extending out from the end of the cavity part. The capacitor 17 is positioned in the cavity part 41. A ring-shaped gasket 5 is disposed between the turnup part 42 and the rear-end cover 16. The turnup part 42, the gasket 5 and the rear-end cover 16 are locked and fixed together through a plurality of bolts 6. The front-end cover 15 and the rear-end cover 16 are respectively disposed on the two ends of the motor housing 14 through bolts 71 and nuts 72. First gaps 43 and second gaps 51 corresponding to the first gaps are respectively disposed on the outer edges of the turnup part 42 and the gasket 5 and correspond to each other. The nuts 72 are disposed in the first gaps 43 and the second gaps 51. A lead wire hole 160 is disposed on the rear-end cover 16.

[0030] Unless otherwise indicated, the numerical ranges involved in the invention include the end values. While particular embodiments of the invention have been shown and described, it will be obvious to those skilled in the art that changes and modifications may be made without departing from the invention in its broader aspects, and therefore, the aim in the appended claims is to cover all such changes and modifications as fall within the true spirit and scope of the invention.
