Patent number: 7096598Abstract: A hair styling brush with reverse airflow. The preferred styling brush has a contoured, bristled body for holding locks of hair in a curved or curled position. The body is perforated, and a blower in the brush draws air in through the perforations across the damp hair. This styling brush preferably is used with a conventional blow dryer or curling iron. When using a blow dryer, warm air from the blow dryer is directed at the lock of hair on the styling brush, while the blower in the styling brush pulls the warm air through the hair. Alternately, after a lock of hair has been styled on a curling iron, the lock then can be cooled rapidly using the styling brush. The styling brush is designed to direct the exhaust air toward the handle. In this way, the user can tell from the temperature of the exhaust when the hair is dry. More specifically, once the hair on the brush is dry, the exhaust air will begin to feel warmer as the evaporation process is no longer cooling it.Type: GrantFiled: July 5, 2000Date of Patent: August 29, 2006Assignee: Natural Volume Systems, L.L.C.Inventor: Tommy Leon Myatt

Patent number: 6925728Abstract: A grooming device having a first unit and upper hand-held unit connected to the first unit is disclosed. A vacuum unit in the first unit creates a vacuum air flow in a vacuum chamber in the hand-held unit, while a heating unit in the first unit generates a heated air flow to a heat chamber in the hand-held unit. The heat chamber and vacuum chamber are contained within a vessel in the hand-held unit. The heat chamber is separated from the vacuum chamber by a wall having regularly spaced pores. When both the vacuum unit and heating unit of the device are switched on, the vacuum flow in the vacuum chamber pulls heated air from the heat chamber through pores in the wall so that dry, heated air flows along the length of the vessel. Thus, hair placed in the vacuum chamber of the hand-held unit is exposed to the combined effect of the vacuum and flow of heated air. In a further embodiment, the wall of the vacuum chamber is heated by a heating element thereby causing the vacuum flow to be heated.Type: GrantFiled: March 10, 2003Date of Patent: August 9, 2005Inventors: Kathleen M.

Thus, the electrothermal body forms a multi-loop inner layer and a multi-loop outer layer around the support wings to increase the heating area of the electrothermal rack, thereby enhancing the heating efficiency of the hair dryer.Type: GrantFiled: July 11, 2003Date of Patent: May 11, 2004Inventor: Shu-Lien Chen

Patent number: 6732449Abstract: The present invention relates to a blower dryer appliance typically used for drying and styling hair. When electrically activated, these appliances virtually always route electrical power to the fan or blower motor prior to or simultaneously with the heating element(s). Semiconducting switching devices used for regulating, controlling and/or switching electrical power generate waste heat that must be dissipated. Typically, heat is conducted and/or channeled away from the semiconducting switching device through a heat sink which is thermodynamic-mechanically coupled to the device. The greater the coverage area of the heat sink, the more waste heat can be dissipated depending on the ability of the heat sink to make contact with cooler, ambient air. This adds costs to the dryer/blower for engineering the heat sink, cost of the sink itself, and necessary design changes in the dryer/blower for accommodating the sink.Type: GrantFiled: April 9, 2003Date of Patent: May 11, 2004Inventor: Walter Evanyk

Patent number: 6725562Abstract: The hair dryer includes a housing body that includes an air intake opening and an air outlet opening. The air outlet opening includes a non-ionized air outlet opening and an ionized air outlet opening. A fan is disposed within the housing body for introducing air into the housing body through the air intake opening and directing the air to the air outlet opening. An ionized air passage mechanism is formed within the housing body and is connected to the ionized air outlet opening. An air ionizing device is disposed within the ionized air passage mechanism for generating ionized air. Under this configuration, ionized air generated by the air ionizing device is discharged from the ionized air outlet opening and non-ionized air is discharged through the non-ionized air outlet opening such that both ionized air and non-ionized air are blown together from the air outlet openings of the hairdryer against hair.Type: GrantFiled: June 12, 2002Date of Patent: April 27, 2004Assignee: Matsushita Electric Works, Ltd.Inventors: Takashi Nakagawa, Takahiro Kumode

Patent number: 6724984Abstract: A hair treatment promoting apparatus in which a reflector provided with a heater for radiating infrared rays is rotated by a motor so that the infrared rays are radiated to the top, back and both sides of a head of a subject. The heater and reflecting plate form a heating device rotated by the motor and a disk is provided which rotates with the motor. The disk is provided with a slit for a home position and slits for stopping arranged on both sides thereof, and energization of the motor is interrupted when the slit for the home position is detected within a prescribed time elapsed from when the slit for stopping is detected in the direction of rotating the heating device, thereby stopping the heating device at the home position.Type: GrantFiled: December 5, 2001Date of Patent: April 20, 2004Assignee: Takara Belmont CorporationInventors: Yuji Kakuya, Keiji Ito, Hironori Mitsui, Koji Yamane, Tomofumi Horio, Masakazu Katsumata

Patent number: 6718651Abstract: The invention relates to a portable, cordless, hair dryer/blower that has an elongated hollow body portion with a mass center line and including therein a blower motor and a heating element and having a posterior end and an anterior end. A handle portion has a longitudinal axis extending substantially transversally from and along the mass center line of the elongated body portion. The handle portion includes switch controls for operating the heating element and the blower motor. A power source has a flat base and a mass center line that, when the power source is attached to the handle portion lies substantially along the longitudinal axis of the handle and the mass center line of the elongated body portion to provide power to the manual controls and to provide a flat base structure for enabling the hair dryer/blower to stand alone.Type: GrantFiled: April 5, 2002Date of Patent: April 13, 2004Inventors: Louis Perez, Walter Evanyk

Patent number: 6691429Abstract: There is provided a stand for use with a hand held hair dryer. The stand selectively cooperates with a handle of the hand held hair dryer to form a tripod and enable a user to operate the hand held hair dryer in a hands-free manner. The stand can telescopically cooperate with the hand held hair dryer in such a manner to allow the hand held hair dryer to be selectively, tilted, angled and/or positioned when rested on or supported against a surface. The stand provides a user with greater flexibility in use and enhances the effectiveness/efficiency of the hand held hair dryer.Type: GrantFiled: November 14, 2002Date of Patent: February 17, 2004Assignee: Conair CorporationInventors: Vito James Carlucci, Jong Sik Lim, Henri Christophe Frederic Joseph Smal
