Abstract

The present invention relates to a hair care device (1), having a handle (3), a application head (4) which can be connected to the handle (3) and has a hair treatment device (5), particularly a bristle and/or a tooth field, and having an ion discharging device (9) with at least one ion outlet (11) for discharging ions onto the hair. According to the invention, the hair care device (1) is characterized in that the application head (4) and/or a part of the housing surrounding the ion outlet (11) has at least one grounding surface for dissipating/limiting electrical charges. Advantageously, the ions are discharged exclusively from the back (8) of the device facing away from the hair treatment device (5), while the grounding surface can be provided on the application head (4) on the front side of the device.

Claims

1. A hair care device with a handle, an application head that can be attached to the handle, which has a hair treatment device comprising a bristle field and/or a tooth field and an ion discharging device for applying ions to the hair in a housing having at least one ion outlet arranged on one of the sides of the device facing away from the hair treatment device, characterized in that the application head and/or a housing component in the vicinity of the ion outlet has at least one first grounding surface for removing and/or limiting electronic charging and the back side of the device is provided with at least one second grounding surface.

2. The hair care device according to claim 1, wherein the first grounding surface and/or the second grounding surface comprises a metal surface, which is applied to a non-conductive component of the application head and/or to the housing component in the vicinity of the on outlet.

3. The hair care device according to claim 1, wherein the first grounding surface is on the outside of a component part.

4. The hair care device according to claim 1, wherein the second grounding surface is on the inside of a component part.

5. The hair care device according to claim 1, wherein a third grounding surface is arranged on the application head.

6. The hair care device according to claim 5, wherein the third grounding surface on the application head, surrounds the hair treatment device and is directly adjacent to the hair treatment device.

7. The hair care device according to claim 1, wherein a first grounding surface on the ion outlet forms a housing surface that encloses a high-voltage element for the emission of ions.

8. The hair care device according to claim 7, wherein the housing part enclosing the ion outlet has an orifice side, comprising an outlet opening is for the discharge of ions, and has at least one additional, closed side of the housing, wherein the first grounding surface is on the closed side of the housing.

9. The hair care device according to claim 8, wherein the orifice side of ion outlet is free of counter electrodes.

10. The hair care device according to claim 1, wherein the second grounding surface is adjacent to the ion outlet and downstream from it, considering the direction of ion discharge.

11. The hair care device according to claim 1, wherein all ion outlets are arranged on the back side of the device facing away from the hair treatment device.

12. The hair care device according to claim 11, wherein the ion outlets are arranged around the edges of the back side of the application head to provide an ion cloud over the back side of the application head.

13. The hair care device according to claim 12 comprising a battery to power the ion discharging device .

14. The hair care device, according to claim 13, wherein the application head and/or the hair treatment device is removably attached to the main body of the device forming the handle.
