Abstract
A battery powered blow dryer having a novel heating element technology that can be powered by an attached battery pack. The heating element includes an infrared light bulb that emits high heat with relatively low power consumption compared to current methods. The present invention patent also describes a unique configuration of battery cells to optimally perform the task of blow drying hair.
Claims20
A battery-operated hair dryer comprising:
- a case having an air flow channel with an air inlet and air outlet;
- a heating element including one or more infrared bulbs positioned within the air flow channel between the air inlet and air outlet;
- power control circuitry coupled to the heating element configured to provide one or more power optimization modes to the heating element, wherein the one or more power optimization modes includes pulse width modulation (PWM) configured to flicker the power on and off to the one or more infrared bulbs;
- and
- at least one battery configured to provide power to the power control circuitry.
2 more elements
A battery-operated hair dryer comprising:
- a case having an air flow channel with an air inlet and air outlet;
- a hybrid heating element positioned within the air flow channel between the air inlet and air outlet, the hybrid heating element including one or more infrared bulbs and one or more resistive wires;
- power control circuitry coupled to the heating element configured to provide one or more power optimization modes to the heating element, including pulse width modulation (PWM) configured to flicker the power on and off to the one or more infrared bulbs;
- a fan assembly positioned within the air flow channel;
- and
- at least one battery configured to provide power to the power control circuitry and fan assembly;
- wherein the fan assembly draws in air through the air inlet, the air flows through the air flow channel and is blown over/through the hybrid heating element to heat the air, and the heated air exits through the air outlet.

A battery-operated hair dryer comprising:
- a case having an air flow channel with an air inlet and air outlet;
- a hybrid heating element including one or more infrared bulbs and one or more resistive wires positioned within the air flow channel between the air inlet and air outlet;
- power control circuitry coupled to the hybrid heating element including pulse width modulation (PWM) of the one or more infrared bulbs;
- a hair temperature sensor coupled to the power control circuitry configured to detect a temperature of hair and adjust the power to the hybrid heating element when a target hair temperature is reached;
- a fan assembly positioned within the air flow channel;
- and
- at least one battery configured to provide power to the power control circuitry and fan assembly,
- wherein the fan assembly draws in air through the air inlet, the air flows through the air flow channel and is blown over/through the heating element to heat the air, and the heated air exits through the air outlet.
