Abstract

A mount for an electric motor, the mount comprising a sleeve for receiving a motor, the sleeve having a longitudinal axis extending between a first end and a second end, wherein the first end comprises a plurality of plurality of projections and the plurality of projections extend along the longitudinal axis. The sleeve may receive the motor via the first end or the second end. The plurality of projections may be spaced around a circumference of the sleeve. The plurality of projections may comprise a pattern of substantially constant frequency around the sleeve. The plurality of projections may be substantially V-shaped with the point extending along the longitudinal axis from the first end of the sleeve.

Claims

1. A motor mount, the mount comprising a sleeve for receiving a motor, the sleeve comprising a longitudinal axis extending between a first end and a second end, wherein the first end comprises a plurality of projections and the plurality of projections project from the first end of the sleeve along the longitudinal axis.

2. The mount of claim 1, wherein the sleeve receives the motor via the first end or the second end.

3. The mount of claim 1, wherein the plurality of projections are spaced around a circumference of the sleeve.

4. The mount of claim 1, wherein the plurality of projections comprises a pattern of constant frequency around the sleeve.

5. The mount of claim 1, wherein the plurality of projections are substantially V-shaped with a point extending along the longitudinal axis from the first end of the sleeve.

6. The mount for a motor of claim 1, wherein a radial seal is provided and the radial seal extends around a circumference of the sleeve.

7. The mount of claim 6, wherein the radial seal is a lip seal.

8. The mount of claim 6, wherein the radial seal is positioned near the first end of the sleeve.

9. The mount of claim 1, wherein the first end comprises a plurality of compression ribs.

10. The mount of claim 9, wherein each one of the plurality of compression ribs is housed within one of the plurality of projections.

11. The mount of claim 1, wherein the second end comprises a plurality of compression ribs.

12. The mount of claim 1, wherein a second seal is provided near the second end of the sleeve.

13. The mount of claim 12, wherein the second seal is a bellow seal.

14. The mount of claim 13, wherein the bellow seal houses a plurality of compression ribs.

15. A hair care appliance comprising:

a casing having a fluid inlet, a fluid outlet and an annular seat; and

a motor mount comprising;

a sleeve for receiving a motor, the sleeve comprising a longitudinal axis extending between a first end and a second end, wherein the first end comprises a plurality of projections and the plurality of projections project from the first end of the sleeve along the longitudinal axis, wherein the first end of the mount is supported by the annular seat.

16. A hair care appliance comprising:

a casing having a fluid inlet, a fluid outlet and an annular seat;

a motor mount supported by the annular seat, the motor mount comprising;

a sleeve for receiving a motor the sleeve having a longitudinal axis extending between a first end and a second end, wherein the first end comprises a plurality of projections, the plurality of projections project from the first end of the sleeve along the longitudinal axis, and the plurality of projections engages with the annular seat.

17. The appliance of claim 16, wherein the appliance comprises a body which houses a heater and a handle which includes the casing.

18. The appliance of claim 17, wherein the appliance comprises a fluid flow path extending from a fluid inlet into the casing to a fluid outlet in the body.

19. The appliance of claim 16, wherein the first end is provided at a downstream end of the motor mount.
