Abstract

The invention relates to a spray nozzle comprising an elastomeric tube ( 1 ) comprising a proximal end ( 7 ) through which a fluid is intended to enter said tube ( 1 ), and a distal end ( 8 ). The spray nozzle also comprises a slit ( 9 ) formed in the elastomeric tube ( 1 ) between the proximal end ( 7 ) and the distal end ( 8 ), for spraying the fluid out from the elastomeric tube ( 1 ). The elastomeric tube ( 1 ) includes a reinforcing element ( 10, 11 ) for limiting deformation of the elastomeric tube ( 1 ). By providing a slit in a tube between the proximal and distal ends of the tube, the slit can be sized to provide a broad spread pattern to the spray. The reinforcing element prevents over-expansion or deformation of the elastomeric tube.

First claim

The invention claimed is:

1. A spray nozzle comprising:
an elastomeric tube comprising a proximal end through which a fluid is intended to enter the tube, and a distal end, the elastomer tube having a longitudinal axis;
a slit formed in the elastomeric tube between the proximal end and the distal end, for spraying the fluid out from the elastomeric tube, the slit opening in response to pressure from the fluid within the elastomeric tube, wherein the slit extends through the elastomeric tube in a non-parallel direction to the longitudinal axis; and
a reinforcing element for limiting deformation of the elastomeric tube caused by the fluid pressure within the elastomeric tube.

2. The spray nozzle according to claim 1 , wherein the elastomeric tube comprises a cylindrical wall, the slit being formed in the cylindrical wall.

3. The spray nozzle according to claim 2 , wherein the slit is arcuate in a non-circumferential direction about the longitudinal axis of the elastomeric tube.

4. The spray nozzle according to claim 2 , wherein the slit extends in a circumferential direction about the longitudinal axis of the elastomer tube.

5. The spray nozzle according to claim 2 , wherein the reinforcing element surrounds side portions of the cylindrical wall, leaving the slit exposed.

6. The spray nozzle according to claim 5 , wherein the reinforcing element extends across the distal end of the elastomeric tube, the distal end of the elastomeric tube being closed.

7. The spray nozzle according to claim 5 , wherein the reinforcing element is formed integrally with the elastomeric tube.

8. The spray nozzle according to claim 7 , wherein the reinforcing element comprises a region of increased thickness of the material forming the elastomeric tube.

9. The spray nozzle according to claim 1 , wherein the reinforcing element is a separate component, secured to the elastomeric tube in a fixed position, that surrounds only an upper part of the elastomeric tube opposite the slit formed in the elastomeric tube.

10. The spray nozzle according to claim 9 , wherein the separate component comprises a housing secured to the elastomeric tube in the fixed position.

11. The spray nozzle according to claim 1 , wherein the slit has opposing edges, the edges being in contact with each other in a closed position when the fluid pressure within the elastomeric tube is below a predetermined pressure.

12. The spray nozzle according to claim 1 , wherein the distal end of the elastomeric tube is open for entering the fluid into the elastomeric tube from both the proximal end and the distal end.

13. A garment steamer comprising:
a steam generator including a chamber and a water supply hose extending into the chamber for supplying water from a reservoir into the chamber for conversion of water into steam;
a heating element for heating a surface within the chamber; and
a spray nozzle within the chamber attached to an end of the water supply hose, the spray nozzle comprising:
an elastomeric tube comprising a proximal end attached to the water supply hose and a closed distal end, the elastomer tube having a longitudinal axis;
a slit formed in the elastomeric tube between the proximal end and the distal end, for spraying the water out from the elastomeric tube onto the heated surface to create steam, the slit opening in response to pressure from the water within the elastomeric tube, wherein the slit extends through the elastomeric tube in a non-parallel direction to the longitudinal axis; and
a reinforcing element for limiting deformation of the elastomeric tube caused by the fluid pressure within the elastomeric tube.

14. The garment steamer according to claim 13 , wherein the distal end of the elastomeric tube is closed.

15. The garment steamer according to claim 13 , wherein the reinforcing element surrounds side portions of the elastomeric tube, leaving the slit exposed, and extends across the distal end of the elastomeric tube, wherein the distal end of the elastomeric tube is closed.

16. The garment steamer according to claim 15 , wherein the reinforcing element is formed integrally with the elastomeric tube.

17. The garment steamer according to claim 16 , wherein the reinforcing element comprises a region of increased thickness of material forming the elastomeric tube.

18. The garment steamer according to claim 13 , wherein the reinforcing element is a separate component, secured to the elastomeric tube in a fixed position, that surrounds only an upper part of the elastomeric tube opposite the slit formed in the elastomeric tube.

19. The garment steamer according to claim 18 , wherein the separate component comprises a housing secured to the elastomeric tube in the fixed position.
