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 (3), an application head (4) that can be attached to the handle (3), which has a hair treatment device (5), in particular a bristle field and/or a tooth field (6), and an ion discharging device (9) for applying ions to the hair, having at least one ion outlet (11), arranged on one of the sides of the device (8) facing away from the hair treatment devices (5), characterized in that the application head (4) and/or a housing component (13) in the vicinity of the ion outlet (11) has at least one first grounding surface (22) for removing and/or limiting electronic charging and the said back side of the device (8), preferably on the inside of a component part, advantageously is provided with at least one second grounding surface (122).

2. The hair care device according to the preceding claim, wherein the first grounding surface (22) and/or the second grounding surface (122) comprises a metal surface, which is applied to a non-conductive body, preferably made of plastic, and/or to the housing component of the application head (4) and/or to the housing component (13) in the vicinity of the ion outlet (11).

3. The hair care device according to any of the preceding claims, wherein the first grounding surface (22) is provided on the outside of a component part.

4. The hair care device according to any of claims 1 through 3, wherein the second grounding surface (22) is provided on the inside of a component part.

5. The hair care device according to any of the preceding claims, wherein a third grounding surface (21) is arranged on the application head (4).

6. The hair care device according to the preceding claim, wherein the grounding surface (21) on the application head (4), surrounds the hair treatment device (5) at least in sections, preferably in the form of a ring, and/or is arranged directly adjacent to the hair treatment device (5).

7. The hair care device according to any of the preceding claims, wherein the first grounding surface (22) on the ion outlet (9) forms a housing surface that encloses a high-voltage element (12) for the emission of ions.

8. The hair care device according to the preceding claim, wherein the housing part (13) enclosing the ion outlet (11) has an orifice side (14), in which an outlet opening (17) is provided for the discharge of ions, and has at least one additional, closed side of the housing (16), wherein the first grounding surface (22) is provided on the closed side of the housing.

9. The hair care device according to the preceding claim, wherein the orifice side (14) of ion outlet (11) is designed to be free of counter electrodes.

10. The hair care device according to any of the preceding claims, wherein the second grounding surface (122) is arranged on a housing component (108), adjacent to the ion outlet (11) downstream from it considering the direction of ion discharge.

11. The hair care device according to the preamble of claim 1 or any of the preceding claims, wherein the single ion outlet (11) or all ion outlets (11) are arranged on the back side of the device (8) facing away from the hair treatment device (5).

12. The hair care device according to any of the preceding claims, wherein the at least one ion outlet (11) or all the ion outlets (11) are arranged around the edges of the back side of the application head (4) in such a way that an ion cloud can be generated over the back side of the application head.

13. The hair care device according to the preceding claim, wherein an energy storage device is provided to power the ion discharging device (9), preferably in the form of a battery and/or a rechargeable battery.

14. The hair care device according to the preceding claim, wherein the application head (4) and/or the hair treatment device (5) is removably attached to the main body of the device (2) forming the handle (3).
