Abstract

Present disclosure discloses a hair treatment device. The hair treatment device includes a body defined with a hair-treatment section and a heating plate disposed in the hair treatment section. The heating element is an electrical conductor. Further, the hair treatment device includes at least one ion generator configured to generate and channelize ions through a groove defined in the body adjacent to the hair-treatment section forming an ion stream. Furthermore, the hair treatment device includes an ion attractor defined in the body. The ion attractor bridges the groove and the heating element, where the heating element attracts ions from the ion stream through the ion attractor for distributing ion stream along a length of the groove. Even distribution of the ions along the length of the groove, provides more area for defrizzing of hair, thereby facilitates effective defrizzing of the hair.

First claim

1 . A hair treatment device, comprising:
a body defined with a hair-treatment section; a heating element disposed in the hair-treatment section, wherein the heating element is an electrical conductor; at least one ion generator configured to generate and channelize ions through a groove defined in the body adjacent to the hair-treatment section forming an ion stream; and an ion attractor defined in the body, bridging the groove and the heating element, wherein the heating element is arranged to attract ions from the ion stream through the ion attractor.

2 . The hair treatment device as claimed in claim 1 , wherein the ion attractor is a guideway defined at a substantially central portion of the body.

3 . The hair treatment device as claimed in claim 2 , wherein the guideway comprises a through opening between the groove and the heating element such that, a part of ion stream flows from the groove towards the heating element.

4 . The hair treatment device as claimed in claim 3 , wherein the through opening includes a cross-sectional area, which is constant throughout its length.

5 . The hair treatment device as claimed in claim 1 , wherein the at least one ion generator is disposed in the body at either ends of the groove.

6 . The hair treatment device as claimed in claim 1 , wherein the at least one ion generator is structured to generate anions.

7 . The hair treatment device as claimed in claim 1 , wherein the groove extends substantially parallel to a longitudinal edge of the heating element.

8 . The hair treatment device as claimed in claim 1 , further comprising a grounding circuit for electrically grounding the heating element.

9 . The hair treatment device as claimed in claim 8 , wherein the grounding circuit comprises:
a printed circuit board; and a conductive member configured to electrically connect the printed circuit board and the heating element.

10 . A hair styler for straightening hair, the hair styler comprising:
a pair of arms pivotally connected to each other at one end; and a hair treatment device as claimed in claim 1 , disposed in at least one arm of the pair of arms.

11 . The hair styler as claimed in claim 10 , wherein the hair treatment device as claimed in claim 1 is disposed in each of the pair of arms.

12 . The hair styler as claimed in claim 10 , wherein each of the pair of arms is elongate, with the hair treatment device disposed at one end, and a grip section defined at another end, opposite to the one end.
