DETAILED DESCRIPTION OF THE INVENTION Referring to the drawings and more particularly to Figs. 1 and 2, there is shown a device in accordance with a preferred embodiment of the present invention generally represented by reference numeral 1. Device 1, as shown, preferably takes the form of a conventional hand held hair dryer having a housing 5 with a lower handle portion 10 and an upper barrel portion 15. Preferably device 1 also has one or more ion generators 20 for generating ions of positive polarity and ions of negative polarity, and one or more ion emitters 25 situated outside housing 5 for emitting ions of positive polarity and ions of negative polarity.

Preferably, housing 5 has a blower 30, an inlet 35, and an air outlet.

Blower 30 is a conventional type blower that is sufficient for generating

airflow. Preferably, blower 30 draws air into housing 5 through air inlet 35, through the upper barrel portion 15 of housing 5, and out air outlet 40.

Preferably, the air exiting air outlet 40 can be directed toward the hair of a user for drying and/or styling.

In addition, housing 5, preferably has a control (not shown) operatively connected to blower 30 for altering the intensity of the airflow, and thereby affecting the overall concentration of ions within the airflow.

Preferably, the control can also be operatively connected to a heater (not shown), and/or the one or more ion generators 20, and/or the one or more ion emitters 25 for controlling the operation of each component.

As shown in Figs. 1 and 2, housing 5 can also have any configuration and/or feature known to be associated with conventional hair dryers. For example, Figs. 3 through 12 show various attachments that can selectively cooperate with housing 5 to manipulate the airflow exiting air outlet 40. Accordingly, the distribution and intensity of the airflow, as well as the aeration of ions with the airflow, is controlled.

Preferably, one or more ion generators 20 is situated in the lower handle portion 10 of housing 5. However, one or more ion generators 20 may also be located in the upper barrel portion 15 of housing 5. Further, one or more ion generators 20 may be located in both the lower handle portion 10 and upper barrel portion 15 simultaneously, as shown in Fig. 1.

Still further, one or more ion generators 20 can be positioned at any

location suitable to optimize the effective operation of device 1.

In addition, one or more ion generators 20, preferably can be any suitable device capable of adjustably generating voltage outputs of varying intensities and of varying polarity combinations. Also, one or more ion generators 20 is/are electronically connected to one or more ion emitters 25. Further, one or more ion generators 20 and one or more ion emitters 25 are configured for safety, as well as for protection from damage caused by extensive use.

Preferably, the one or more ion emitters 25 is/are situated outside housing 5. Also preferably, one or more ion emitters 25 can selectively minimize dilution of ions with the airflow. Still further, preferably the one or more ion emitters 25 is/are located in a casing 45 on housing 5. Casing 45 can be integral with housing 5 or removable to allow easy access to the one or more ion emitters 25 for cleaning and/or replacement thereof. This can be important as dust and other air particles or contaminates tend to collect on ion emitters and can thereby interfere with the ionization process. Preferably, the casing configuration can also further reduce the degree to which the one or more ion emitters 25 is/are directly exposed to the airflow exiting air outlet 40, and thereby minimize the degree to which air born contaminants negatively affect the operation of the one or more ion emitters 25.

In addition, preferably the one or more ion emitters 25 can have any

configuration sufficient to emit ions having selectively different polarities and intensities, as well as to conform to the configuration and operation of device 1. For example, one or more ion emitters 25 can be in the form of a conductive needle, an array of such needles, a conductive plate, or any other like structure. Also, one or more ion emitters 25 can be formed from any material sufficient to effectively emit ions and conform to the configuration and operation of device 1, such as for example, a conductive metal, a conductive polymer, or a carbon material. Further, the one or more ion emitters 25 can be made of a conductive semi-fluid, such as a silicon gel. Still further, one or more ion emitters 25 preferably creates a concentration of ions having either a negative polarity or a positive polarity, or some combination thereof. One or more ion emitters 25 can also preferably be arranged to create a predictable area of concentrated ions sufficient to encompass the area proximate the head of a user and to intensify the exposure of ions to the hair. If device 1 employs blower 30 for generating an airflow, preferably one or more ion emitters 25 is/are situated at a distance from the airflow.

Having described in detail the preferred embodiment of the present invention, it is appreciated that details may be modified in a variety of ways and that alternative embodiments are also within the scope of the present invention. Thus, device 1 can preferably be any device suitable for use with hair, such as for example, a hatchet hair dryer, as shown in Fig. 13, an air curling iron, as shown in Fig. 14, a hooded salon style hair dryer, as

shown in Figs. 15 and 16, a hair straightening iron or brush, as shown in Figs. 17 and 18, or a conventional hair curling iron, as shown in Fig. 19.

The process of using device 1 comprises, regardless of the embodiment employed, adjustably creating various ion concentrations.

Each concentration has a different polarity combination so that the ions are created at a distance from the head and/or hair of a user in order to optimize the known beneficial effects of ionization to the user. Further, if the embodiment of device 1 has a blower for generating an airflow, the process of using the device can preferably include adjustably creating the various concentrations of ions at a distance from the airflow generated by the blower in order to minimize any dilution resulting from direct exposure to the airflow and to maximize ionization of the air proximate the head and/or hair of the user. Still further, the process of using device 1 can preferably include employing a variety of attachments, see Figs. 3 through 12, adapted for selective cooperation with the device for adjustably controlling the mix and distribution of the ion concentration.

The present invention having been thus described with particular reference to the preferred forms thereof, it will be obvious that various changes and modifications may be made therein without departing from the spirit of the present invention as defined herein.
