Abstract

Embodiments of the invention provide an electric blower, including a diffuser having a cover and an impeller sequentially disposed at one side in a shaft direction thereof, a front disposed at the other side in the shaft direction of the diffuser, and an elastic body mounted between the front and the diffuser to support the diffuser.

Claims

1. An electric blower, comprising:

a diffuser comprising a cover and an impeller sequentially disposed at one side in a shaft direction thereof;

a front disposed at the other side in the shaft direction of the diffuser; and

an elastic body mounted between the front and the diffuser to support the diffuser.

2. The electric blower of claim 1, wherein the diffuser comprises a support part provided with a receiving space in which the elastic body is received.

3. The electric blower of claim 1, wherein the elastic body is configured of a spring.

4. The electric blower of claim 1, wherein the diffuser further comprises a cover seating part formed to contact an inner side of the cover, which is mounted outside the impeller;

and

a guide part formed at an edge of a circumference thereof to guide air introduced through an inlet of the cover.

5. The electric blower of claim 1, further comprising:

a shaft of which an end is inserted into the impeller in the shaft direction; and

a nut fastened with the end of the shaft, being embedded in the impeller.

6. The electric blower of claim 5, wherein the nut is configured of a hexagonal nut.

7. The electric blower of claim 5, wherein the nut is screw-fastened with the end of the shaft in a direction opposite to a direction in which the impeller rotates.

8. An electric blower, comprising:

a cover having a central portion provided with an inlet into which air is introduced;

an impeller provided with a wing which is disposed between the impeller and the cover;

a diffuser comprising the impeller disposed at one side in a shaft direction thereof and protrudedly provided with a cover seating part contacting an inner side of the cover;

a front configured to be disposed at the other side in the shaft direction of the diffuser; and

an elastic body configured to be mounted between the front and the diffuser to support the diffuser.

9. The electric blower of claim 8, wherein the diffuser comprises a support part provided with a receiving space in which the elastic body is received.

10. The electric blower of claim 8, wherein the elastic body is configured of a spring.

11. The electric blower of claim 8, wherein the diffuser further comprises a guide part formed at an edge of a circumference thereof to guide air introduced through the inlet.

12. The electric blower of claim 8, further comprising:

a shaft of which an end is inserted into the impeller in the shaft direction; and

a nut fastened with the end of the shaft, being embedded in the impeller.

13. The electric blower of claim 12, wherein the nut is configured of a hexagonal nut.

14. The electric blower of claim 12, wherein the nut is screw-fastened with the end of the shaft in a direction opposite to a direction in which the impeller rotates.

15. An electric blower, comprising:

a cover;

an impeller provided with a wing to introduce external air through an inlet formed on the cover;

a shaft of which an end is inserted into the impeller in a shaft direction; and

a nut fastened with the end of the shaft, being embedded in the impeller.

16. The electric blower of claim 15, wherein the nut is configured of a hexagonal nut.

17. The electric blower of claim 15, wherein the nut is screw-fastened with the end of the shaft in a direction opposite to a direction in which the impeller rotates.
