Battery level indicator may allow the user to know when hair drying device 100 needs to be charged; for instance, and without limitation, battery level indicator may change the light from green to yellow to red as battery level decreases. For another example, and without limitation, battery level indicator may emit light while the hair drying device 100 is charging, and cease illumination when charging is complete. Battery level indicator may emit a first color of light while charging is occurring and a second color of light when charging is complete, may blink to indicate charging is currently occurring, or the like. Any suitable pattern of illumination in response to charging status of hair drying device 100 may be used.
With continued reference to FIG. 1, in another non-limiting example, display 140 may include a digital screen. In an embodiment, display 140 may be used to present one or more hair drying parameters. As used in this disclosure, “hair drying parameter” is a configuration of a setting or measurement that controls and/or monitors the drying process of user's hair using hair drying device 100. In an embodiment, hair drying parameter may include a temperature parameter, wherein the temperature parameter is a setting of the temperature of the flow generated by at least a fan via heating element (i.e., voltage or electrical current supplied to heating element) as described above. In another embodiment, hair drying parameter may include a speed parameter, wherein the speed parameter is a setting of the velocity of the flow generated by at least a fan (i.e., spinning speed of plurality of blades of at least a fan) as described above. In a further embodiment, hair drying parameter may include a duration parameter, wherein the duration parameter is a setting of the length of the hair drying process (i.e., using hair drying device 100). In a non-limiting example, display 140 may provide information about various settings of hair brushing device such as, without limitation, temperature, speed, duration, and the like. Additionally, or alternatively, display 140 may allow the user to select or adjust hair drying parameters (i.e., settings) of hair drying device 100. In a non-limiting example, user may select power on/off or various hair drying parameters of hair drying device 100 via display 140. Further, display 140 may provide notifications or alerts to the user; for instance, and without limitation, when hair drying device needs to be cleaned or when a maintenance task needs to be performed on one or more internal components as described above.
With further reference to FIG. 1, hair drying device 100 may include a cooling mechanism 144 configured to cool electric motor 104. In some embodiments, cooling mechanism 144 may include a heat pipe cooling system. As used in this disclosure, a “heat pipe cooling system” is a system that utilize one or more heat pipes to transfer heat away from electric motor 104 and dissipate transferred heat into surrounding environment, wherein the heat pipe is a passive heat transfer device that uses a sealed, evacuated tube filled with a working fluid to transfer heat from one location to another. In a non-limiting example, heat pipe cooling system may include one or more heat pipes that are mounted within shroud of electric motor 104 and in contact with the windings of electric motor or other heat generating components such as, without limitation, heating element as described below in this disclosure. As electric motor operates, heat may be generated within the windings, wherein such heat may be transferred to one or more heat pipes via conduction. Such heat dissipation of heat pipe cooling system may be used to regulate the temperature of electric motor 104 and/or other heat generating components.
Still referring to FIG. 1, additionally, or alternatively, cooling mechanism 144 of hair drying device 100 may further include a venturi-based cooling system. As used in this disclosure, a “venturi-based cooling system” is a system that utilizes a Venturi effect to create a pressure differential that drives a flow (i.e., air flow) through a cooling device. In a non-limiting example, cooling device may include a series of fins or other heat dissipating structures that are exposed to the flow to transfer heat away from electric motor 104 and/or other heat generating components. A “Venturi effect,” is a phenomenon that occurs when a fluid (i.e., air) flows through a constricted area of a pipe or channel resulting in a decrease in pressure, thereby increasing the velocity of airflow. In a non-limiting example, hair drying device 100 with venturi-based cooling system may force air through a narrow channel which creates a pressure differential that drives the air with increased velocity through cooling device. Persons skilled in the art will be aware, after reviewing the entirety of this disclosure, of different cooling mechanism 144 may be integrated within hair drying device 100 configured to dissipate heat explained herein.
Now referring to FIG. 2, an exemplary embodiment of a hair drying device 100 with a dual-fan system is illustrated. As used in this disclosure, a “dual-fan system” is a mechanical system that uses at least two fans to generate fluid flow such as, without limitation, airflow. Dual-fan system may include two or more fans that are arranged in a specific configuration to achieve a desired performance objective of hair drying device 300. In a non-limiting example, at least a fan 112 of hair drying device 300 may include a first fan 204 (i.e., fore blade) and a second fan 208 (i.e., aft blade), wherein both fans may be identical from at least a fan 112 as described above. In some cases, first fan 204 and second fan 208 may be disposed on either side of electric motor 104 of hair dryer device 304. In some embodiments, first fan and second fan may be arranged in a sequence on shaft 212 of electric motor 104 at a distance. In such embodiment, dual-fan system may result in at least two fans being run at a lower revolution per minute (RPM) instead of a conventional RPM (e.g., 15,000 RPM); therefore, aids with noise reduction. Additionally, or alternatively, gear 116 may be used to operate at least two fans of dual-fan system; for instance, and without limitation, at least two fans may attach to a same shaft connected to gear 116. In other cases, at least two fans of dual-fan system may operate separately; for instance, and without limitation, gear 116 may include a second gear connected to a separate shaft with second fan 208 attached. Electric motor 104 may be sandwiched between at least two fans. Further, plurality of blades of at least two fans may rotate bidirectionally (i.e., in different directions). In such embodiment, dual-fan system may aid with generating a more direct (i.e., straight) flow path.
