HEATED HAIR BRUSH

Abstract

A heated hair brush (B) comprises heated protrusions (HP): non-heated protrusions (NHP); a control unit (C) arranged for controlling a temperature of the heated protrusions (HP); and a mechanism (FC. SC) arranged for controlling a position of the non- heated protrusions (NHP) relative to a position of the heated protrusions (HP). In a first mode (I). the non-heated protrusions (NHP) extend beyond the heated protrusions (HP), and the temperature of the heated protrusions (HP) exceeds 100? C. In a second mode (II). the non-heated protrusions (NHP) do not extend beyond the heated protrusions (HP), and the temperature of the heated protrusions (HP) does not exceed 50? C. The heated protrusions (HP) may be connected to a first carrier (FC), and the non-heated protrusions (NHP) may be connected to a second carrier (SC). In one embodiment, a distance (d) between the first and second carriers is modifiable. wherein in the first mode (I), the distance (d) is smaller than in the second mode (II). In another embodiment. the second carrier (SC) is laterally moveable with regard to the first carrier (FC), whereby in the first mode (I), the non-heated protrusions (NHP) are parallel to the heated protrusions (HP) whereby the non-heated protrusions (NHP) extend beyond the heated protrusions (HP), while in the second mode (II). the non-heated protrusions (NHP) are at an angle to the heated protrusions (HP) whereby the non-heated protrusions (NHP) do not extend beyond the heated protrusions (HP).

Description

BRIEF DESCRIPTION OF THE DRAWINGS

[0011] FIGS. 1-3 illustrate embodiments of the invention.

DESCRIPTION OF EMBODIMENTS

[0012] FIG. 1 illustrates a first embodiment of the invention. by means of side views of a heated hair brush in a first mode I (left view) and a second mode II (right view). A handle H is mounted to a brush base B. The brush has heated protrusions HP and non-heated protrusions NHP. In the first mode I. the non-heated protrusions NHP extend beyond the heated protrusions HP. In the second mode II. the non-heated protrusions NHP do not extend beyond the heated protrusions HP. A control unit C is arranged for controlling a temperature of the heated protrusions HP in such a way. that in the first mode I. the temperature of the heated protrusions HP exceeds 100? C. (e.g. at least 150? C. and preferably at about 170-200? C.), while in the second mode II. the temperature of the heated protrusions HP is set to be higher than normal skin temperature but does not exceed 50? C. In the second mode II. the temperature could be between 40? C. and 50? C. e.g. between 40? C. and 45? C. The control unit C may have user buttons allowing a user to set the desired temperature and the desired mode I or II. a temperature sensor arranged for measuring an actual temperature of the heated protrusions (HP) or a first carrier on which the heated protrusions are mounted. and a processor arranged for controlling the actual temperature to match the desired temperature. all of which are not shown.

[0013] The heated protrusions HP may be made from aluminum/or die casted with a coating (c.g. ceramic). The non-heated protrusions NHP may be made from a glass fiber filled type or rubber type of material. The heated protrusions HP and the non-heated protrusions NHP may be alternatingly positioned.

[0014] FIGS. 2 and 3 show two embodiments of how a mechanism arranged for controlling a position of the non-heated protrusions NHP relative to a position of the heated protrusions could be made. The mechanism could be operated manually or by means of an actuator (not shown). If operated manually. then if the position of the non-heated protrusions NHP is set at the position of the second mode. then this action would prompt the control unit to set the temperature of the heated protrusions HP to a value of between 40? C. and 50? C. If operated by an actuator. then triggered by a user input selecting the second mode II. a controller may simultaneously control the actuator to go to the position for the second mode II and set the temperature of the heated protrusions HP to a value of between 40? C. and 50? C. The actuator may be controlled to only go to the position for the second mode II once the actual temperature of the heated protrusions HP is low enough to be safe. c.g. not exceeding 50? C. as measured by a temperature sensor that may be present to control the temperature of the heated protrusions HP in the first mode I. An indicator (e.g. a LED that may be orange colored) may signal to a user that the device is waiting for the temperature of the heated protrusions HP to be safe.

[0015] The heated protrusions HP are connected to a first carrier FC. and the non-heated protrusions NHP are connected to a second carrier SC. As usual, the first carrier FC may be provided with heater elements (not shown), e.g. PTC heaters or (metal) ceramic heaters.

[0016] In the embodiment of FIG. 2. a distance d between the first carrier FC and the second carrier SC is modifiable. FIG. 2 shows the distance d in the second mode II. In the first mode I. the distance d is smaller than in the second mode II whereby the non-heated protrusions NHP extend beyond the heated protrusions HP.

[0017] In the embodiment of FIG. 3. the second carrier SC is laterally moveable with regard to the first carrier FC. In the first mode I (like in FIG. 2 but with the distance d being smaller than shown in FIG. 2). the non-heated protrusions NHP are parallel to the heated protrusions HP whereby the non-heated protrusions NHP extend beyond the heated protrusions HP. In the second mode II, the non-heated protrusions NHP are at an angle to the heated protrusions HP whereby the non-heated protrusions NHP do not extend beyond the heated protrusions HP.

[0018] It should be noted that the above-mentioned embodiments illustrate rather than limit the 5 invention, and that those skilled in the art will be able to design many alternative embodiments without departing from the scope of the appended claims. For example, in the first mode, the temperature of the heated protrusions may be switchable, e.g. between 170? C. and 200? C. In the claims, any reference signs placed between parentheses shall not be construed as limiting the claim. The word comprising does not exclude the presence of elements or steps other than those listed in a claim. The word a or an 10 preceding an element does not exclude the presence of a plurality of such elements. The invention may be implemented by means of hardware comprising several distinct elements, and/or by means of a suitably programmed processor. In the device claim enumerating several means, several of these means may be embodied by one and the same item of hardware. Measures recited in mutually different dependent claims may advantageously be used in combination. CLAIMS
