Description
A HAIR ROLLER
Field of the Invention
The present invention relates to a hair roller and to a hair roller kit
Background of the Invention
Hair rollers are commonly used for treating or styling hair, for instance to shape or curl the hair. When rolled into a person's hair, the hair can be heated to change the internal structure of the hair and cause the hair to curl. Hot hair rollers are pre-heated before being rolled into the hair where the heat stored in the thermal mass of the hot hair roller is transferred to the hair.
Summary of the Invention
According to a first aspect of the present invention there is provided a hair roller. The hair roller comprises: a housing, a thin-film heater, and an electrical connector. A section of hair can be wrapped onto the housing and, in use, the thin-film heater heats the hair roller to transfer heat to the hair wrapped around the housing. The electrical connector is connectable to an external electrical energy supply. In use, connecting the electrical connector the external electrical energy supply enables electrical energy to be delivered to the thin-film heater to cause heating of the hair roller. The thin-film heater is an electrically-powered heater.
According to a second aspect of the present invention there is provided a hair roller. The hair roller comprises: a housing, an electrically-powered heater, and an electrical connector. A section of hair can be wrapped onto the housing and, in use, the electrically-powered heater heats the hair roller to transfer heat to the hair wrapped around the housing. The electrical connector is removably connectable to an electrical supply connector of a power applicator. In use, the electrical connector is to receive electrical energy from the electrical supply connector for delivery to the electrically-powered heater. The power applicator is configured so that the electrical energy can supplied to the electrical connector from the electrical supply connector when the hair is wrapped around the housing of the hair roller.
The electrically-powered heater may comprise a resistive heater. In other embodiments, the electrically-powered heater may comprise an inductive heating system comprising an inductor and a susceptor where the susceptor heats the hair roller, for instance by heating the housing. The resistive heater may comprise a thin-film heater wrapped around the portion of housing on which the hair is rolled.
Where the hair roller comprises a thin-film heater, the thin-film heater may comprise one or more resistive heating elements. The thin-film heater can provide a large contact area with the housing relative to the size of the heater.
The resistive heating element(s) may be supported on, or embedded within, a superstructure of the thin-film heater. The resistive heating element(s) may be supported on an insulating substrate. The insulating substrate may comprise a polyimide substrate. The resistive heating element(s) may be sandwiched between layers of an insulating material The heating element(s) of the thin-film heater may comprise: a cut metal shim, an etched foil resistor, or a printed resistor. The heating element(s) may be connected to terminals at each end. The heating element(s) may have an electrical resistance of between 0.2 ohm and 5 ohms. The heating element(s) may be laid out in parallel lines that are connected at the ends. The heating element(s) lines may be spaced apart from each other by between 0.3mm and 5mm. The small spacing between the heating element(s) lines means the heating element can cover a larger surface area of the housing.
The thin-film heater may have a thickness of less than 50iiim. The thin-film heater may weigh less than 3 grams. The thin-film heater may be is wrapped around the housing. The thin-film heater may have electrical connections that pass through the housing.
The thin-film heater 14 may use more than 250W. The thin-film heater may use approximately 270W. The thin-film heater 14 may use up to 400W. The thin-film heater may heat the hair roller to a temperature of 120 °C over a period of approximately 10s.
The hair roller may comprise an insulator wrapped around the housing to encapsulate the thin-film heater. The insulator may define an external surface of the hair roller. The insulator can protect the electrically-powered heater from damage arid prevent a user contacting a heating element of the electrically-powered heater.
The hair roller may comprise a temperature monitoring unit to measure or react to the temperature of the housing or of the electrically-powered heater. The temperature monitoring unit allows the hair roller to be heated to, and controlled at, a specified temperature or temperature profile over a period of heating the electrically-powered heater. The temperature monitoring unit may comprise a thermal switch. The thermal switch may comprise a bimetallic strip.
Heating the hair roller allows a user to have free hands once the hair roller is fixed in the user's hair. Using a thin-film heater allows the hair roller to be made lightweight in comparison with a pre-heated hair roller that relies on a substantial thermal mass, which can be very heavy, to store the energy from the pre-heating station. Due to the low thermal mass of a thin-film heater, the hair roller can be heated up rapidly. The rapid temperature increase of a low thermal mass heater makes heating the hair rollers on a user's head easier. Moreover, the hair roller can be cold on insertion into the hair that is to be treated meaning that there is no cause for discomfort to a hair roller user or burning of their fingers. The rapid heat up and the ease of insertion can mean that the total styling time for a user will be lower. As no pre-heat is required before insertion, the initial temperature to which the hair roller is heated can be lower meaning the treated hair will not be as damaged by the treatment.
According to a third aspect of the present invention there is provided a hair roller power applicator for applying electrical energy to a hair roller comprising an electrically-powered heater. The power applicator comprises: an electrical supply connector, an electrical energy source to supply electrical energy to the electrical supply connector, and a control system to control the supply of electrical energy to the electrical supply connector. The electrical supply connector is removably connectable to an electrical connector of the hair roller. The electrical supply connector is to, in use, deliver electrical energy to the electrical connector for delivery to the electrically-powered heater. The power applicator is configured so that the electrical energy can be supplied to the electrical connector when a section of hair on a user's head is wrapped around the hair roller.
The electrical supply connector may be configured to guide the electrical supply connector to connect with the electrical connector of the hair roller. The electrical supply connector may be shaped to guide the electrical supply connector to connect with the electrical connector of the hair roller. The electrical supply connector and/or the electrical connector may comprise a magnet to aid the connecting of the electrical supply connector to the electrical connector.
The hair-heating temperature of the hair roller can be controlled with the power applicator in the present invention making the hair roller more versatile. Accordingly, a variety of heating profiles (heating to a range of temperatures over a heating period) can be implemented in the hair roller, in this way, the hair roller can accommodate different volumes of hair rolled onto the hair roller of the present invention. The hair roller can also accommodate different amounts of water content in hair rolled onto the hair roller of the present invention. The hair roller of the present invention can be heated to and maintained at a range of temperatures over a longer period than for a pre-heated hair roller that relies on having enough thermal mass to store the required thermal energy before insertion into hair. For pre-heated hair rollers, the temperature passively decreases once the pre-heated hair roller is removed from its heating source; in contrast, the hair roller of the present invention can be heated to a desired temperature by the power applicator after the hair rollers have been inserted into the hair. The maximum temperatures to which the hair roller of the present invention can be heated to can be lower than the initial heated temperature of a pre-heated hair roller because the hair roller of the present invention is already in the hair before being heated. Accordingly, the treated hair will not be as damaged by the treatment when the hair roller of the present invention is used. Additionally, being able to control the hair-heating temperature means that the user's fingers are not burnt during use of the hair roller in the hair, for instance if manipulation in situ is required.
Because the electrical supply connector is removably connectable to an electrical connector of the hair roller and the power applicator is configured so that the electrical energy can be supplied to the electrical connector when the hair roller is inserted into a user's hair on their head, the electrically-powered heater of the hair roller can be powered once the hair roller has been inserted but still permit a user to move around freely. There is no need to rely on power cables fixed to the hair rollers to supply the electrical energy to power the hair rollers, which can make the hair rollers uncomfortable to use and prevent a user with performing other tasks at the same time as treating their hair. Thus, the hair rollers of the present invention are less cumbersome and awkward to use. The hair rollers of the present invention are more comfortable for a user to wear. Furthermore, the hair roller of the present invention is also tidier than a hair roller with fixed power cables, which can be messier as part of a set of cabled hair rollers inserted in a user's hair.

Detailed Description of the Invention
A hair roller 10 according to the present invention is shown schematically in Figure 1. Hair can be rolled around the hair roller 10 so that the hair can be curled. The hair roller 10 is heatable so that heat is transferable to the hair rolled around the hair roller 10 thereby curling the hair and to fixing the hair in a curled shape.
In the embodiment shown in the figures, the hair roller 10 is generally cylindrical in shape and extends from a first end 24 to a second end 26. The hair roller 10 has a cylindrical surface 22 that contacts hair rolled around the hair roller 10. When the hair roller is heated, heat is transferred to the hair from the cylindrical surface 22, which may be referred to as the working surface. Optionally, as in the embodiment shown in Figure 1, the hair roller 10 comprises a plurality of bristles 28 that aid in gripping the hair rolled onto the hair roller 10. Each bristle of the plurality of bristles 28 projects in an outwardly direction of the cylindrical surface 22. In another embodiment, the hair roller 10 is covered with a fibrous material forming the cylindrical surface 22 to reduce hair slipping around when wrapping hair around the hair roller 10. The hair roller 10 may, or may not, comprise the plurality of bristles 28 in the embodiment where the hair roller 10 is covered with a fibrous material.
The hair roller comprises a housing 20 that defines the general shape of the hair roller on which a section of hair is w-rappable, in this instance the cylindrical shape of the hair roller 10. Figure 2 schematically illustrates a cross-sectional view through the hair roller 10 of Figure 1. The housing 20 defines an enclosure 21 for containing and protecting certain components of the hair roller 10. In the illustrated embodiment, the housing 20 comprises a substantially hollow tube and an end cap located each of the first 24 and second 26 ends. The housing 20 may have a diameter of between 25mm and 50mm. The housing 20 may have a wall thickness of between 0.3mm and 2mm. The housing 20 comprises a material that can sustain being held at a temperature suitable for heat treating hair, for example a temperature of more than 150°C. The housing 20 may comprise a plastics material.
The hair roller 10 comprises an electrically-powered heater. The electrically-powered heater is to heat the hair roller 10 so that the hair roller transfers heat to hair rolled around the hair roller 10.
The electrically-powered heater may comprise a resistive heater. As explained above, other electrically-powered heater configurations than a resistive heater may be implemented to heat the hair roller 10. In the embodiment shown in the figures, the electrically-powered heater comprises a resistive thin-film heater 14. The thin-film heater 14 may comprise one or more resistive heating elements. The heating element(s) may be connected to terminals at each end that, in turn, permit connection of the thin-film heater 14 to other electrical components of the hair roller 10. Thin-film heaters include lightweight and flexible heaters that have a high tensile strength and a high resistance to tearing despite having a thickness that may be a fraction of a millimetre. For example, the thin-film heater 14 may have a thickness of less that 50t.im. Being thin permits the thin-film heater 14 to be lightweight, for example less than 3 grams. Thin-film heaters can have a low thermal mass thereby reducing the overall weight of the hair roller 10, which can make the use of the hair roller 10 more comfortable for a user. Thin-film heaters have a resistive heating element(s) that is supported on, or embedded within, a superstructure of the thin-film heater. For example, the resistive heating element may be supported on an insulating substrate, such as a polyimide substrate. The resistive heating element may be sandwiched between layers of an insulating material, such as layers of polyimide. The heating element of the thin-film heater 14 may comprise, a cut metal shim, an etched foil resistor, or a printed resistor. The heating element may have an electrical resistance of between 0.2 ohm and 5 ohms. The heating element circuit may have a tortuous, or snaking, path that allows control of the heat emitted by the thin-film heater 14. For instance, the heating element may emit more, or less, heat in one heating zone than in another zone thereby permitting the hair roller to be heated with a desired heating pattern. The heating element circuit may be laid out so that the hair roller 10 is heated evenly across the whole of the cylindrical surface 22. In one example, the heating element may be laid out in parallel lines that are connected at the ends. The heating element lines may be spaced apart from each other by between 0.3mm and 5mm, for example spaced apart by 0.4mm. The heating element of the thin-film heater 14 may comprise a single strip wrapped on to the housing 20 with small gap, such as 0.3mm, between each turn. The heating element of the thin-film heater 14 may comprise a shim that can substantially cover the area of the housing 20 working surface and have small slots, such as 0.3mm, cut into the shim. The thin-film heater 14 is a low-temperature heater, that is the heater is not configured to cause combustion by generating heat. The thin-film heater 14 may use more than 250W. For example, the thin-film heater may use 270W. In some examples, the thin-film heater 14 may use up to 400W. The thin-film heater 14 may heat the hair roller 10 to a temperature of 120 °C over a short period -for example, the thin-film heater 14 may heat the hair roller 10 to this temperature in lOs or less at a power supply of 270W. The thin-film heater 14 is generally cylindrically shaped to match the housing 20. For instance, the flexible thin-film heater 14 is wrapped around the tubular housing 20. In some examples, the thin-film 14 is securely fixed to the housing 20, for example on the cylindrical surface of the housing 20. The thin-film heater 14 has electrical connections that pass through the housing 20 wall into the enclosure 21.
An insulator 16 is wrapped around the housing 20 thereby encapsulating the thin-film heater 14 between the insulator 16 and the housing 20. The insulator 16 protects the thin-film heater 16 from damage and helps prevent a user contacting the heating element of the thin-film heater 14. The insulation 16 may be in addition to an insulating layer on top of the heating element of the thin-film heater N. Alternatively, the insulator 16 may be the only insulating layer between the heating element of the thin-film heater 14 and external surface of the hair roller 10. The insulator 16 forms the external cylindrical surface 22 of the hair roller 10. Heat generated in the heater is therefore transferred through the insulator 16 to hair rolled onto the hair roller. The insulator may comprise any suitable material that can sustain being held at a temperature suitable for heat treating hair. The insulator 16 may comprise a plastics material, a metal, or a metal alloy, or a fibrous material, for example. It will be understood that in some embodiments, the insulator 16 is not present and the thin-film heater 14 can form the outer surface of the hair roller 10. Thus, heat will be transferred from the hair roller 10 directly from a surface of the thin-film heater 14.
A thermally conductive layer, which is to act as a thermal spreader layer, may be placed between the thin-film heater 14 arid the insulator 16. For example, the thermally conductive layer may comprise an aluminium shim. The thermally conductive layer may be located between the insulation 16 and any insulating layer on top of the heating element of the thin-film heater 14. A second thermally conductive layer, which is also to act as a thermal spreader layer, may be placed between the thin-film heater 14 and the housing 20. For example, the second thermally conductive layer may comprise an aluminium shim. The first and second thermally conductive layers may be electrically insulated from the thin-film heater 14. As thermal spreader layers, the first and second thermally conductive layers assist the heat distribution evenly across the hair roller surface As illustrated in Figure 2, the hair roller may comprise a temperature monitoring unit 34 that is mounted to the inside of the tubular housing 20 and that measures, or reacts to, the temperature of the housing 20, which is heated by electrically-powered heater in use. In some embodiments, the temperature monitoring unit is instead mounted to, or incorporated in, the electrically-powered heater itself For example, the temperature monitoring unit may be a surface-mounted component of the thin-film heater 14. In some embodiments, the temperature monitoring unit 34 is a temperature sensor that provides a temperature measurement signal. In other embodiments, the temperature monitoring unit 34 is a thermal switch, for example a bimetallic strip, that opens and cuts off the supply of electrical energy to the heater when the desired heating temperature for hair on the hair roller has been exceeded.
As shown in Figure 2, the hair roller 10 comprises a circuit board 50 that supports circuitry connecting certain electrical components of the hair roller 10. Wire harnesses may be used to connect some components to each other and/or the circuit board. For instance, the temperature monitoring unit 34 may be wired to the circuit board The hair roller 10 comprises an electrical connector 18 as shown in Figures 1 and 2. The electrical connector 18 is located at the first end 24 of the hair roller 10 but could be located in another suitable position on the hair roller 10. The electrical connector 18 is removably connectable to a supply of electrical energy external to the hair roller 10 so that electrical energy can be supplied to the hair roller 10 through the electrical connector 18 and then delivered to the electrically-powered heater to cause heating of the electrically-powered heater. The electrical connector 18 is electrically connected to the electrically-powered heater so that the supplied electrical energy can be delivered to the electrically-powered heater. Thus, the electrically-powered heater is powered by the external supply of electrical energy. In some embodiments, as shown in Figure 2, the I.3 electrical connector 18 is mounted on the circuit board 50, although the electrical connector may instead be separate component.
The electrical connector 18 is configured to cooperate with, and electrically connect with, an electrical supply connector through which electrical energy is deliverable to the electrical connector 18. In cooperating with one another, the electrical connector 18 and electrical supply connector may respectively comprise complementary male and female shapes that facilitate removably connecting the electrical connector 18 and electrical supply connector together. As explained further below, the electrical supply connector may be provided in an energy delivery device. The energy delivery device is configured such that the electrical energy can be supplied when the hair roller is inserted into a section of hair on a user's head. The electrical connector 18 and electrical supply connector may comprise one or more electrical energy transfer pins through which the electrical energy can be transmitted. In some embodiments, the electrical connector 18 and electrical supply connector may comprise additional connector pins that provide for the transmission of other electrical signals, such as control signals that may be exchanged between the hair roller 10 and an energy delivery device as described herein and/or temperature control signals from the temperature monitoring unit 34.
Figure 3 schematically illustrates a cross-sectional view through an embodiment of a hair roller power applicator 100 according to the present invention As also shown in Figure 3, the hair roller power applicator 100 may be part of a hair roller kit 200, according to the present invention, and comprising at least one hair roller 10 as described herein and the hair roller power applicator 100. The hair roller kit 200 may comprise a plurality of hair rollers 10 The power applicator 100 is an energy delivery device and comprises a housing 120 that defines an enclosure 121 for containing and protecting certain components of the power applicator 100. The housing 120 has a shape that makes it easy for a user to handle the power applicator 100, for instance to apply electrical energy to a hair roller 10 as described further below. In this instance, the housing 120 has a generally cylindrical shape. The housing 120 may have a diameter of between 25mm and 50mm, for example to match the hair roller 10 diameter. The housing 20 may have a wall thickness of between 0.3mm and 2mm. The housing 20 may comprise a plastics material.
The power applicator 100 comprises an electrical supply connector 102. The electrical supply connector 102 is removably connectable and electrically engageable with the electrical connector 18 of the hair roller 10.
