A hair grooming apparatus includes a vacuum mechanism and a vacuum chamber that is in fluid communication with the vacuum mechanism. The vacuum chamber includes a first opening positioned at a first end of the vacuum chamber with a first cross-sectional area and arranged to accommodate an insertion of a section of hair and a second opening positioned at a second and opposite end of the vacuum chamber. The vacuum chamber further includes a wall extending between the first and second openings and defining an interior bore. An air pocket is formed along a section of the interior bore extending from a first location located proximate to the first opening with a second cross-sectional area to a second location positioned between the first location and the second opening with a third cross-sectional area. The second cross-sectional area is greater than both the first cross-sectional area and the third cross-sectional area.

This invention relates to apparatus and methods for regulating a parameter on a handheld appliance, such as a hair styling appliance. A hair styling apparatus comprises a body having at least one arm bearing a hair styling heater; a temperature sensor arranged to sense a temperature of the hair styling heater and generate a temperature sense signal; and a power supply unit comprising a magnetic energy transfer element, an AC input coupled to a first side of the magnetic energy transfer element, a heater drive output coupled to a second side of the magnetic energy transfer element and to the hair styling heater to power said hair styling heater, and a power controller configured to regulate the heater drive output. A power controller is coupled to the temperature sense signal and configured to regulate the heater drive output of the power supply so as to control the temperature of the hair styling heater responsive to the temperature sense signal.

A hair styling device is described herein that comprises an exposed heating surface, a heating element to heat the exposed heating surface, a temperature sensor to measure a temperature of at least one of the heating element or the exposed heating surface, a heating element interface coupled to the heating element, and a network communication circuit. The hair styling device further comprises a device controller that includes a control circuit to provide a control signal to the heating element interface to modify operation of the heating element according to an instruction received by the network communication circuit over a network from an application. In an embodiment, the device controller further includes a command status monitor to generate a success or fail message, indicative of a success or failure of the instruction in the hair styling device, for transmission by the network communication circuit over the network to the application.

A hair gathering accessory can be formed as a comb or a brush device, and has a handle formed with a body. On one side of the body are a plurality of tines (e.g. comb teeth, brush bristles, etc.). On the other side of the body is a heat shield that is attached to the body and which extends away from the body some distance. The tines are used to gather a portion of hair while the hair gathering accessory is being held by a person, and the heat shield protects the person whose hair has been gathered from the heat of a hair iron that is applied to the gathered portion of hair.

The second cross-sectional area is greater than both the first cross-sectional area and the third cross-sectional area.

A hair cooling and dehumidification apparatus includes a wearable headgear. The wearable headgear includes an outer layer, an insert layer, and an inner layer. The outer layer includes a supply port. The supply port is in fluid communication with a high-pressure storage tank via a vortex tube. The insert layer, detachably attached to the outer layer, includes a network of ducts and detachable insert elements. The ducts are in fluid communication with the supply port to receive a cooling gas from the vortex tube and distribute the cooling gas to the hair. The detachable insert elements are detachably attached to the insert layer via fasteners. The detachable insert elements, spaced apart to accommodate the network of ducts there between, comprise desiccant materials embedded within for absorbing moisture. The inner layer is proximal to the hair of the user to transfer the cooling gas to the hair.
