Publication number: 20180110313Abstract: A hair dryer comprises a main body (1), wherein an interior of the main body (1) is formed with an airflow channel, and the airflow channel is formed with an air inlet (11) and an air outlet (12) on the main body (1). The hair dryer further comprises an electrically powered fan (2) provided in the airflow channel and configured to draw external air via the air inlet (11) and then discharge via the air outlet (12), and comprises a rotatable component (3) provided at the air outlet (12) and configured to rotate to change a direction of an airflow formed by rotation of the electrically powered fan (2). A hair dryer airflow direction is changed by the rotatable component (3), thus addressing problems of a non-uniform airflow or ion airflow and a narrow emission surface.Type: ApplicationFiled: March 24, 2016Publication date: April 26, 2018Inventor: Wai Ho Michael Keong

Publication number: 20180020795Abstract: The present application provides a hair curler and a method using for same. The hair curler comprises a main body (1). The main body (1) comprises a first proximal end (2) and a first distal end (3); a first internal space (4) is formed inside the main body (1); a first elongated slot (6) communicated with the first internal space (4) is formed on the first proximal end (2); a first opening (8) of the first elongated slot (6) is formed on the first proximal end (2). The hair curler further comprises a first movable arm (7) movably disposed in the first internal space (4). A heating member for heating hair (33) is disposed on a slot wall of the first elongated slot (6) and/or the first movable arm (7). The hair curler is simple, practicable, safe and convenient.Type: ApplicationFiled: August 21, 2015Publication date: January 25, 2018Inventor: Wai Ho Michael Keong

Publication number: 20170202332Abstract: A curling iron that winds a lock of hair about a barrel includes a body that surrounds the barrel and forms a hair-receiving space accessed through an opening in the body. The opening includes a circumferential portion extending about a distal end of the barrel, and a slot extending axially from the circumferential portion toward a proximal end of the barrel. The slot portion is disposed at a longitudinal end of the curling iron for receiving a lock of hair that is elongated parallel to the slot portion and pushed in crosswise. A resilient finger mounted to the body projects and normally closes the slot portion and holds the lock of hair in the hair-receiving space. A gating coupling connects the barrel to the body and provides relative movement between the barrel and the body, between open and closed position, for inserting and releasing a lock of hair.Type: ApplicationFiled: July 7, 2015Publication date: July 20, 2017Inventors: Wai Ho Michael Keong, Wai Ming Lam

Patent number: 9521890Abstract: A hair styling iron includes a handle to which a barrel is mounted, a heating element in the barrel, a rotary drive including a motor that rotates the barrel, a control circuit including a timer, and a momentary drive switch which is user actuable and connected to the control circuit for control of the motor. Actuation of the drive switch must be maintained to operate the rotary drive. The control circuit monitors at least one change of state of the drive switch to determine a starting time, and actuates an alarm after an elapsed time measured from the starting time. The elapsed time is calculated by the control circuit in direct proportion to an angle of rotation of the barrel relative to the handle that occurs between a first actuation of the drive switch and release of the drive switch immediately following the first actuation of the drive switch.Type: GrantFiled: January 18, 2016Date of Patent: December 20, 2016Assignee: Kenford Industrial Company Ltd.Inventors: Wai Ming Lam, Wai Ho Michael Keong

Patent number: 9414661Abstract: A rotary hair brushing and curling appliance includes a hollow rotary barrel of a thermally conductive material mounted to rotate on a handle, and having an external hair-engaging surface. Silicone rubber bristles are mounted on the barrel, and arranged in first and second sets projecting from first and second arcuate surfaces which are axially elongated and circumferentially spaced apart. Heating elements abut respective abutment surfaces inside the barrel. A reversible motor rotates the barrel. The first and second arcuate surfaces each occupy 10% to 40% of the external surface and are subtended at the axis by respective first and second central angles. The heating elements are positioned outside first and second sectors defined by the first and second central angles, focusing the conductive heat transfer to the adjacent relatively large unobstructed external areas of the barrel.Type: GrantFiled: February 8, 2013Date of Patent: August 16, 2016Assignee: KENFORD INDUSTRIAL COMPANY LTD.Inventor: Wai Ho Michael Keong

Publication number: 20160213117Abstract: A hair styling appliance has a temperature regulation controller to mitigate heat damage to the hair. The appliance includes a pair of heated jaws that can be closed to grip the hair. A power control circuit responds to an activation sensor that senses when the jaws are closed, and a temperature sensor that senses the temperature of a heating element on the jaws. The power control circuit, in response to an activation sensor output, starts monitoring the rate of change of the heating element temperature, and, in response to a rate of decrease above a predetermined level, operates the heating element at a power level lower than a steady state power level.Type: ApplicationFiled: December 19, 2013Publication date: July 28, 2016Applicant: KENFORD INDUSTRIAL COMPANY LTD.Inventor: Wai Ho Michael Keong

Patent number: 9237787Abstract: A hair styling iron has a handle to which a heated barrel is mounted and a motor for moving the barrel. The iron includes a drive switch which is user actuable and connected to the control circuit for controlling operation of the motor. The control circuit includes a timer and monitors at least one change of state of the user-actuable drive switch to determine a starting time, and actuates an alarm, or another response, such as a reversal of the motor to unwind the hair, after an elapsed time measured from the starting time. The elapsed time may be user-selected or calculated automatically depending upon the length of hair wound onto the barrel, with compensation for barrel temperature.Type: GrantFiled: October 26, 2011Date of Patent: January 19, 2016Assignee: KENFORD INDUSTRIAL COMPANY LTD.Inventors: Wai Ming Lam, Wai Ho Michael Keong
