Abstract

An atomizer nozzle system, in particular for an electrohydrodynamic atomizer (1), wherein a nozzle cap (40) comprises a plurality of nozzles (10, 11, 12) and, in order to form a nozzle (10, 11, 12) comprises at least one nozzle opening (21, 22, 23), at least one nozzle channel and at least one nozzle socket, wherein the nozzle cap is arranged on at least one carrier and wherein the carrier comprises a nozzle connector for each nozzle socket, wherein the nozzle cap is arranged on the carrier in a releasably fastened manner.

First claim

The invention claimed is:

1. An atomizer nozzle system, wherein a nozzle cap comprises a plurality of nozzles and, in order to form a nozzle comprises at least one nozzle opening, at least one nozzle channel and at least one nozzle socket,
wherein the nozzle cap is arranged on at least one carrier and wherein the at least one carrier comprises a nozzle connector for each nozzle socket of the at least one nozzle socket,
wherein the nozzle cap is arranged on the at least one carrier in a releasably fastened manner, and
wherein the nozzle cap engages, with an elastic section on the nozzle connector, around a connecting flange and forms a seal on the nozzle connector by elastic deformation.

2. The atomizer nozzle system as claimed in claim 1 , wherein the nozzle cap is manufactured at least partially from a flexible material.

3. The atomizer nozzle system as claimed in claim 2 , wherein the flexible material comprises a flexible electrical insulator.

4. The atomizer nozzle system as claimed in claim 1 , wherein the at least one carrier is manufactured from a rigid material.

5. The atomizer nozzle system as claimed in claim 1 , wherein the nozzle cap is secured on the at least one carrier by elastically tensioning latching elements or tensioning a flexible material.

6. The atomizer nozzle system as claimed in claim 1 , wherein the nozzle cap comprises a base structure, wherein the base structure is manufactured from a more rigid material in comparison with a nozzle structure, said base structure comprising at least one connecting element for forming a preferably releasable connection with the at least one carrier.

7. The atomizer nozzle system as claimed in claim 6 , wherein the base structure comprises a base plate or a base frame on which the nozzle structure is arranged, and the base structure is manufactured from a plastic.

8. The atomizer nozzle system as claimed in claim 1 , wherein
the nozzle cap comprises at least three nozzle openings,
each nozzle opening of the at least three nozzle openings having
an assigned nozzle channel, and
an assigned nozzle socket, and

the at least three nozzle openings are spaced apart from one another to a maximum degree in a nozzle area and arranged following one another along a zig zag line.

9. An atomizer nozzle system, wherein a nozzle cap comprises a plurality of nozzles and, in order to form a nozzle comprises at least one nozzle opening, at least one nozzle channel and at least one nozzle socket,
wherein the nozzle cap is arranged on at least one carrier and wherein the at least one carrier comprises a nozzle connector for each nozzle socket of the at least one nozzle socket,
wherein the nozzle cap is arranged on the at least one carrier in a releasably fastened manner, and
wherein the at least one nozzle opening of the nozzle projects out of a plane of the nozzle cap, wherein an edge of the nozzle which projects out is embodied as a continuously curved curve, and the edge of the nozzle is asymmetrical on an edge side with respect to an opposite edge side of the nozzle, has greater curvature by at least a factor of 1.5.

10. The atomizer nozzle system as claimed in claim 1 , wherein the nozzle cap and/or a base plate and/or a carrier plate are embodied in one piece, manufactured using an injection molding method.

11. The atomizer nozzle system as claimed in claim 1 , wherein the nozzle cap and a base plate and/or a carrier plate are/is embodied in one piece, manufactured using a multi-component injection molding method or are connected to one another.

12. The atomizer nozzle system as claimed in claim 1 , wherein the nozzle connector has a cylindrical connecting flange with a peripheral sealing ring or a sealing bead which is integrally formed onto the cylindrical connecting flange, and the nozzle socket forms a corresponding cylindrical receptacle, in order to provide an interlocking, seal-forming form fit.

13. The atomizer nozzle system as claimed in claim 1 , wherein the nozzle connector has a conical connecting flange, and the at least one nozzle socket forms a corresponding conical receptacle, in order to provide an interlocking, seal-forming form fit.

14. The atomizer nozzle system as claimed in claim 1 , wherein the at least one nozzle channel is embodied shaped as a conical section or as a conical cap and forms an end channel toward the at least one nozzle opening.

15. The atomizer nozzle system as claimed in claim 14 , wherein the end channel comprises a cylindrical or conical tubular section, and the at least one nozzle opening is between 0.1 millimeters (mm) to 0.3 mm, and a length of the nozzle channel is between 4 mm to 6 mm.

16. The atomizer nozzle system as claimed in claim 1 , wherein the at least one nozzle opening is between 0.1 millimeters (mm) to 0.3 mm, and a length of the at least one nozzle channel is between 4 mm to 6 mm.

17. The atomizer nozzle system as claimed in claim 1 , wherein an electrical contact element, comprising a high-voltage contact, is formed in the nozzle connector, and wherein the electrical contact element projects into a fluid channel, the fluid channel is guided through the electrical contact element, and a distance between the electrical contact element and the at least one nozzle opening is between 5 millimeters (mm) and 20 mm.

18. The atomizer nozzle system as claimed in claim 17 , wherein the distance between the electrical contact element and the at least one nozzle opening is between 11 mm and 15 mm.

19. An atomizer nozzle system, wherein a nozzle cap comprises a plurality of nozzles and, in order to form a nozzle comprises at least one nozzle opening, at least one nozzle channel and at least one nozzle socket,
wherein the nozzle cap is arranged on at least one carrier and wherein the at least one carrier comprises a nozzle connector for each nozzle socket of the at least one nozzle socket,
wherein the nozzle cap is arranged on the at least one carrier in a releasably fastened manner, and
wherein an electrical contact element, comprising a high-voltage contact, is formed in the nozzle connector, wherein the electrical contact element projects into a fluid channel.

20. The atomizer nozzle system of claim 19 , wherein the fluid channel is guided through the electrical contact element, and a distance between the electrical contact element and the at least one nozzle opening is between 5 millimeters (mm) and 20 mm.
