Abstract: A handheld vacuum cleaner includes a fluid flow path extending from a dirty air inlet to a clean air outlet, a main body, and a motor assembly positioned in the main body and along the fluid flow path. The motor defines a motor rotational axis. The handheld vacuum cleaner also includes a cyclonic chamber positioned in the fluid flow path. The cyclonic chamber defines a separator axis. The separator axis and the motor rotational axis form an obtuse angle extending between the cyclonic chamber and the motor assembly. The handheld vacuum cleaner further includes a pre-motor filter in the fluid flow path downstream from the cyclonic chamber and upstream from the motor assembly, a plenum in the fluid flow path immediately upstream from the motor assembly, and a sensor positioned on the plenum. The sensor is operable to measure a characteristic of the fluid flow path.

Abstract: A hair appliance in which the axis of air flow through the appliance is generally in a parallel first direction through one end of the appliance and the handle and then exits the hair appliance in a direction perpendicular to the first direction. The air flow through the handle is not heated. Thus, special heat resistance and/or heat shielding materials are not required in the handle. In this manner, the handle may be sized in a manner that ergonomically fits a user's hand. Further, moisture may be provided from the hair appliance. The moisture may be directed towards a user's hair by a negative pressure that results from the heated air flows proximate the moisture region. In one embodiment, the moisture generation unit may be an ultrasonic vibration unit using a piezoelectric vibrator. In one embodiment, the hair styling appliance may be a paddle dryer.

Abstract: A handheld vacuum cleaner (10, 1010) includes a main body (22, 1022) with a handle (98, 1098) and a bottom surface (102) upon which the vacuum cleaner is configured to be positioned on a horizontal surface (106), a motor assembly (114, 1114) positioned in the main body, and a cyclonic separator assembly (26) removably coupled to the main body. The cyclonic separator assembly includes an inlet nozzle (42) having a dirty air inlet (14, 1014) positioned at a front (50, 1050) of the handheld vacuum cleaner when the cyclonic separator assembly is coupled to the main body, a cyclonic chamber (30, 1030) in fluid communication with the dirty air inlet, and a dirt collection region (38) configured to receive debris separated in the cyclonic chamber. The handheld vacuum cleaner further includes a release actuator (438) configured to release the cyclonic separator assembly from the main body when actuated by a user. The release actuator is accessible from a bottom (94) of the main body.

Abstract: A handheld vacuum cleaner (10) includes a fluid flow path extending from a dirty air inlet (14) to a clean air outlet (18), a main body (22), and a motor assembly (114) positioned in the main body (22) and along the fluid flow path. The motor defines a motor rotational axis. The handheld vacuum cleaner (10) also includes a cyclonic chamber (30) positioned in the fluid flow path. The cyclonic chamber (30) defines a separator axis. The separator axis and the motor rotational axis form an obtuse angle extending between the cyclonic chamber (30) and the motor assembly (114). The handheld vacuum cleaner (10) further includes a pre-motor filter in the fluid flow path downstream from the cyclonic chamber (30) and upstream from the motor assembly (114), a plenum (386) in the fluid flow path immediately upstream from the motor assembly (114), and a sensor (402) positioned on the plenum. The sensor (402) is operable to measure a characteristic of the fluid flow path.
