Abstract

A plasma device for treating surfaces, in particular surfaces of fabrics. In order to allow for better ease of handling, an elongate housing is provided which can be manipulated with one hand and in which a plasma source is arranged. The plasma source has a plateau surface that extends in the longitudinal direction of the housing and includes at least one electrode via which plasma can be dispensed onto the surface to be treated. A center of gravity M and a geometrical center G are located at a distance of less than 20 mm from one another.

Claims (26)

1. A plasma device for treating surfaces of fabrics, the plasma device comprising:

an elongate housing being formed to be operated with one hand;

a plasma source arranged in said housing, said plasma source having a plateau surface running in a longitudinal direction of said housing, said plateau surface having at least one electrode for producing a plasma to be applied to a surface to be treated;

the plasma device having a center of gravity M and a geometrical center G, and said center of gravity M and said geometrical center G are spaced by a distance A of less than 20 mm.

2. The plasma device according to claim 1 , wherein said housing has a cross-section with an oval shape.

3. The plasma device according to claim 2 , wherein said oval-shaped cross-section of said housing is adjusted to the palm of a hand to enable a hand of a user to grip said housing in a form-fit.

4. The plasma device according to claim 1 , which comprises a holding frame for said plasma source with a given arrangement and/or with a given adjustment in respect of a weight thereof.

5. The plasma device according to claim 1 , wherein the center of gravity M and the geometrical center G are disposed at a spacing distance A of less than 10 mm.

6. The plasma device according to claim 5 , wherein the spacing distance A of less than 5 mm.

7. The plasma device according to claim 1 , wherein the center of gravity M and the geometrical center G are identical.

8. The plasma device according to claim 1 , wherein said plasma source is spring-loaded and in a non-use state of the plasma device projects beyond said housing and in a use state is impressed at least partially into said housing.

9. The plasma device according to claim 1 , wherein a geometrical longitudinal axis of the plasma device intersects a first circular surface with a radius R1≤5.0 mm, and wherein the center of gravity M forms a center point of the first circular surface.

10. The plasma device according to claim 9 , wherein a geometrical transverse axis of the plasma device intersects a second circular surface with a radius R2≤5.0 mm, and wherein the center of gravity M forms a center point of the second circular surface.

11. The plasma device according to claim 10 , wherein a geometrical vertical axis of the plasma device intersects a third circular surface with a radius R3≤5.0 mm, and wherein the center of gravity M forms a center point of the third circular surface.

12. The plasma device according to claim 11 , wherein the geometrical longitudinal axis, the geometrical transverse axis, and the geometrical vertical axis of the plasma device intersect a ball with a radius RK<5.0 mm, and wherein the center of gravity M forms a center point of the ball.

13. The plasma device according to claim 1 , wherein a geometrical transverse axis of the plasma device intersects a circular surface with a radius R2≤5.0 mm, and wherein the center of gravity M forms a center point of the circular surface.

14. The plasma device according to claim 1 , wherein a geometrical vertical axis of the plasma device intersects a circular surface with a radius R3≤5.0 mm, and wherein the center of gravity M forms a center point of the circular surface.

15. The plasma device according to claim 11 , wherein the plasma device is embodied symmetrically about at least one of the geometrical longitudinal axis, the geometrical transverse axis or the geometrical vertical axis.

16. The plasma device according to claim 1 , which comprises a switch for selectively switching the plasma device on and off, and wherein the center of gravity M and the switch are arranged offset with respect to the geometrical center G.

17. The plasma device for treating surfaces, the plasma device comprising:

an elongate housing configured to be operated with one hand, said housing having a housing upper part and a housing lower part;

a plasma source arranged in said housing, said plasma source having a plateau surface running in a longitudinal direction of said housing and having at least one electrode for generating a plasma to be applied to the surface to be treated;

wherein a center of gravity M of the plasma device and a geometrical center G of the plasma device are distanced from one another by a spacing distance A that is less than 20 mm; and

wherein the center of gravity M is distanced from the geometrical center G in a direction of said housing upper part.

18. The plasma device according to claim 17 configured for treating surfaces of fabrics.

19. The plasma device according to claim 17 , wherein said plasma source is spring-loaded and in a non-use state the plasma device projects beyond said housing and in a use state is impressed at least partially into said housing.
