a fan assembly positioned within the air flow channel configured to draw in air through the air inlet, blow air over/through the one or more heating elements to heat the air, and the heated air exits through the air outlet;
power control circuitry coupled to the one or more heating elements and the fan assembly;
one or more sensors coupled to the control circuitry configured to detect a temperature of the hair; and
a rechargeable battery pack configured to provide power to the power control circuitry and fan assembly.
2 . The battery-operated hair dryer of claim 1 , further comprising adjust the power to the one or more heating elements when an ideal hair temperature is reached.
3 . The battery-operated hair dryer of claim 1 , wherein the case includes a handle portion and the rechargeable battery pack is positioned within the handle portion.
4 . The battery-operated hair dryer of claim 1 , wherein the rechargeable battery pack forms a handle portion configured to plug into the case.
5 . The battery-operated hair dryer of claim 1 , wherein the rechargeable battery pack includes electrical connectors that connect the batteries to the electronics and power the components.
6 . The battery-operated hair dryer of claim 1 , wherein the rechargeable battery pack includes an electric connector that may be used to recharge the batteries and/or power the hair dryer.
7 . The battery-operated hair dryer of claim 6 , further comprising a power cord plugged directly into the electric connector power the hair dryer.
8 . The battery-operated hair dryer of claim 7 , wherein the power cord allows the blow dryer to be used while the batteries are charging.
9 . The battery-operated hair dryer of claim 1 , wherein airflow is directed over the one or more batteries during fan assembly operation to cool the rechargeable battery pack.
10 . The battery-operated hair dryer of claim 1 , wherein the handle portion includes one or more air inlets configured to allow airflow over the rechargeable battery pack.
11 . A battery-operated hair dryer comprising:
a case having an air flow channel with an air inlet and air outlet with a handle portion;
one or more heating elements positioned within the air flow channel between the air inlet and air outlet;
a fan assembly positioned within the air flow channel being configured to draw in air through the air inlet, blow over/through the heating element to heat the air, and the heated air exits through the air outlet;
power control circuitry configured to control the one or more heating elements and fan assembly;
one or more sensors coupled to the control circuitry configured to detect a temperature of the hair and adjust the power to the one or more heating elements when an ideal hair temperature is reached; and
a rechargeable battery pack positioned within the handle portion configured to provide power to the heating element, power control circuitry and fan assembly.
12 . The battery-operated hair dryer of claim 11 , wherein the rechargeable battery pack includes electrical connectors that connect the batteries to the electronics and power the components.
13 . The battery-operated hair dryer of claim 11 , wherein the rechargeable battery pack includes an electric connector that may be used to recharge the batteries and/or power the hair dryer.
14 . The battery-operated hair dryer of claim 13 , further comprising a power cord plugged directly into the electric connector power the hair dryer.
15 . The battery-operated hair dryer of claim 14 , wherein the power cord allows the blow dryer to be used while the batteries are charging.
16 . The battery-operated hair dryer of claim 11 , wherein the handle portion includes one or more air inlets configured to allow airflow over the rechargeable battery pack.
17 . The battery-operated hair dryer of claim 16 , wherein the airflow over the rechargeable battery pack reduces the surface temperature of the rechargeable battery pack.
18 . A battery-operated hair dryer comprising:
a case with a handle portion having an air flow channel with one or more air inlets and an air outlet;
one or more heating elements and a fan assembly positioned within the air flow channel between the air inlet and air outlet,
power control circuitry configured to control the one or more heating elements and fan assembly;
a rechargeable battery pack positioned within the handle portion configured to provide power to the heating element, power control circuitry and fan assembly
wherein the fan assembly draws in air through the one or more air inlets, the air flows through the air flow channel over/through the heating element and the rechargeable battery pack, and the air exits through the air outlet.
19 . The battery-operated hair dryer of claim 18 , further comprising a hair temperature sensor coupled to the power control circuitry configured to detect a temperature of the hair and adjust the power to the one or more heating elements when an ideal hair temperature is reached.
20 . The battery-operated hair dryer of claim 18 , wherein the rechargeable battery pack includes an electric connector that may be used to recharge the batteries and/or power the hair dryer using a power cord plugged directly into the electric connector.
