Disclosed is an attachment for a hand held appliance comprising an inlet; an outlet; and a fluid flow path between the inlet and the outlet, wherein the outlet comprises at least one slot extending from near an inlet end of the attachment towards a distal end of the attachment and wherein the outlet is at least partially defined by an external surface of the attachment wherein fluid emitted from the outlet is blown along the external surface. The slot may extend substantially along the length of the attachment and fluid emitted from the outlet is attracted to the surface of the attachment. The outlet may comprise a plurality of slots radially spaced around the attachment. Fluid emitted from the outlet flows around the external surface of the attachment and is tangential to the external surface of the attachment. The attachment has a longitudinal axis extending from the first end to the distal end and the at least one slot may be parallel to the longitudinal axis, alternatively the at least one slot is non-parallel to the longitudinal axis. The attachment may further comprise a flow directing element between the inlet and the outlet. Also disclosed is an appliance including such as attachment.

A cleaning appliance (60) comprising a cleaner head (1) rotatably attached to a duct (61). The cleaner head (1) comprises a main body (2) having an agitator chamber (10), an axle (21) that extends into the chamber (10), a drive assembly (7) mounted on the axle (21), and an agitator (8) rotatably mounted within the agitator chamber (10) so as to surround the drive assembly (7). The drive assembly (7) is coupled to the agitator (8) such that torque generated by the drive assembly (7) is transmitted to the agitator (8). Furthermore, the drive assembly (7) is mounted along the axle (21) such that the centre of gravity of the cleaner head (1) is located on or near a vertical plane (63) containing the rotational axis (62) about which the cleaner head (1) rotates relative to the duct (61).

Disclosed is a hair care appliance comprising a body, a fluid flow path extending from a fluid inlet into the appliance to a fluid outlet from the body, a heater for heating fluid in the fluid flow path, a pre-heater located upstream of the heater and a thermal safety device positioned between the pre-heater and the heater. The pre-heater may comprise a resistive element. The pre-heater may be electrically connected to the heater via a heater circuit. The thermal safety device may be electrically connected to the heater via the heater circuit. When the appliance is activated, fluid may flow from the fluid inlet through the pre-heater, past the thermal safety device, through the heater and on to the fluid outlet. The thermal safety device may extend orthogonal to a longitudinal axis A-A of the body.

Humidifying apparatus includes a body and a nozzle detachably mounted on the body. The body includes a chamber, a water tank for supplying water to the chamber, and a motor-driven impeller for generating an air flow over water stored in the chamber. An ultraviolet radiation emitting lamp irradiates water stored in the chamber. The air flow is humidified with water from the chamber, and conveyed to the nozzle for emission from the apparatus. A sensor detects the position of the nozzle relative to the body, and a drive circuit controls the actuation of the lamp depending on an output from the sensor.
