Furthermore, the drawings are in simplified form and are not to precise scale. For purposes of convenience and clarity, directional terms may be used with respect to the drawings. Directional terms are not to be construed to limit the scope of the disclosure. Furthermore, the disclosure, as illustrated and described herein, may be practiced in the absence of an element that is not specifically disclosed herein.
Referring to the drawings, wherein like reference numerals correspond to like or similar components throughout the several Figures, FIG. 1 schematically illustrates in cross sectional view an embodiment of a hairbrush heating device 100. Hairbrush cavity 20 of hairbrush heating device 100 is illustrated including an open-topped cavity into which a hairbrush can be placed to be heated. A hairbrush cavity can be cylindrical with a round cross section. In other embodiments, the hairbrush cavity can include an oval, square, triangular, or other similar cross-sectional shape. Hairbrush cavity 20 is illustrated with a hairbrush 90 including hairbrush bristles 92 and handle 94 placed there within. Hairbrush cavity 20 is operable to selectively heat hairbrush 90 when it is placed there within. Hairbrush cavity 20 includes inlet apertures 22 operable to receive a flow of hot air from an air heating circuit 28 and outlet apertures 24 operable to permit hot air to flow from hairbrush cavity 20 back into the air heating circuit 28.
An air heating circuit 28 can include various alternative embodiments. In the embodiment of FIG. 1, the air heating circuit 28 can be defined to include a return plenum duct 60, a blower motor and fan 30, a heating element 40, and an air supply plenum duct 50.
Heat can be selectively applied to hairbrush 90 according to a number of criteria. A user can be presented with an on/off switch for manual selection. A user can be presented with control options for intensity of heat to be applied to the hairbrush, for example, selecting a power output of heating element of the air heating circuit 28. A user can be presented with a cycle heat option which heats a hairbrush for a particular period of time, and after the period, the heat is cycled off. Such a cycle heat option can additionally include a dial or other scalar input to control a length or degree of heating. In another embodiment, an electronic switch can be used to detect a hairbrush placed within the hairbrush cavity, and heating of the hairbrush can be selectively activated and deactivated based upon whether the electronic switch detects the presence of the hairbrush. In another embodiment, a temperature sensor can be used to detect air temperature within the hairbrush cavity, and heating can be activated and deactivated based upon measuring and maintaining a desired temperature within the hairbrush cavity. In the embodiment of FIG. 1, a sensor operable to detect presence of a hairbrush 90 is embodied as a proximity switch 70 and is used to detect presence of hairbrush 90 within hairbrush cavity 20. Proximity switch 70 can include any electromechanical switch capable of generating a signal based upon whether an object such as a hairbrush is pressing upon the switch. In one embodiment, proximity switch can employ magnetics to detect a hairbrush configured with a metallic or magnetic plate to provide an input to the proximity switch. In another embodiment, a plurality of hairbrushes can be employed, for example, with different quick response (QR) codes imprinted upon an end of the hair brush, and the proximity switch can include a camera device configured to read the QR codes and control the hairbrush heating device to provide customizable heating cycles based upon which hairbrush is placed within the device.
One advantage of the hairbrush heating device 100 of FIG. 1 is that by controlling heating within hairbrush cavity with proximity switch 70, such that the heating element used to heat the hairbrush is only on at desired times, thereby conserving electrical power usage. Another advantage is that the air heating circuit 28 is a fluidic circuit, meaning that hot air is supplied to hairbrush cavity 20 through inlet apertures 22 and is removed through outlet apertures 24, such that air can make a continuous circuit through hairbrush heating device 100 without substantial air intake from outside of the device. Such a fluidic circuit system is helpful in that the handle 94 extending from the device will not have hot air blowing outwardly upon it making the handle hot to the touch, and the unit can be quieter than a similar unit that draws in air and expels air, with the entire flow of air being internal to the unit and thereby avoiding air rush noises associated with drawn or expelled air.
FIG. 2 illustrates in perspective view the hairbrush heating device 100 of FIG. 1. Hairbrush heating device 100 is illustrated including hairbrush cavity 20, outer housing 110, control hardware 120, and power cord 130.

Rubberized pads 212 can additionally be placed upon a bottom of outer housing 210 to aid in preventing the device from moving when a user places or removes a hairbrush from hairbrush cavity 220. Hairbrush cavity 220 includes inlet apertures 222 operable to receive a flow of heated air from air supply plenum duct 250, and hairbrush cavity 220 includes outlet apertures 224 operable to provide a flow of return air to air return plenum duct 260. Hairbrush cavity 220 includes hairbrush cavity opening 226 configured to receive a portion of a hairbrush. In the particular embodiment of FIG. 3, hairbrush cavity opening 226 is open. In other embodiments, hairbrush cavity opening 226 can be covered or air flow there through can be interrupted, for example, with elastic flaps or a removable cap, for example, to retain heat within hairbrush cavity 220. Blower heater assembly 230 is connected to air return plenum duct 260 and receives a flow of return air. Blower heater assembly 230 propels and heats the supplied air and provides a flow of heated air to air supply plenum duct 250.

Power cord 237 supplies power to blower motor 231, and power cord 236 supplies power to heating element coils 234. Blower heater assembly 230 can be controlled directly by an external controller, for example, with changing voltages of electrical power being supplied through power cord 236 and power cord 237. In another embodiment, blower heater assembly 230 can include a dedicated controller attached to or contained within blower heater assembly 230. Air entering blower heater assembly 230 is propelled by blower fan 232 and heated by heating element coils 234, such that a flow of heated air is propelled from blower heater assembly 230 for use in heating a hairbrush.
Heated air can be supplied to a hairbrush cavity to selectively heat a hairbrush within the cavity. FIG. 6 schematically illustrates in cross sectional view an infrared heating element useful to additionally or alternatively heat a hairbrush within a hairbrush cavity. Hairbrush cavity 420 is illustrated, including hairbrush cavity opening 426 and optional flaps 428. An infrared heating element 430 is illustrated including a circuitous loop of resistive metal configured to release heat energy in the form of infrared emissions into hairbrush cavity 420 and includes electrical connections 432 and 434, which can be connected to an electrical power source. Infrared emissions can be used in isolation to heat a hairbrush, or infrared emissions can be used in combination with an air heating circuit 28 as is illustrated in FIG. 1 to cooperatively heat a hairbrush. Temperature sensor 440 is located within hairbrush cavity 420, such that infrared heating element 430 can be selectively energized to maintain hairbrush cavity 420 at a desired temperature or within a desired temperature range. Temperature sensor 440 may be provided in addition to a sensor operable to detect presence of a hairbrush within hairbrush cavity 420. An infrared heating element can include any device that translates electrical energy into radiative heat and can include a resistive element, for example, with a black or dark surface, or a light bulb operable to maximize radiative heat output.
Infrared energy is absorbed more readily by darker objects than lighter objects. A hairbrush can be utilized in combination with the infrared heating element of FIG. 6, for example, with black bristles and a white handle, such that areas that are intended to be heated can reach higher temperatures than areas not intended to be heated. In one embodiment, an inner surface of hairbrush cavity 420 can be coated with a reflective material, such that infrared energy emitted by infrared heating element 430 is more efficiently transferred to the hairbrush within hairbrush cavity 420.
