An electrically heated cigarette smoking device includes a heater unit, heater blades for applying heat to portions of a cigarette that is supported within the heater unit, the heater unit having an opening adapted to receive an end of a cigarette and adapted to position the end of the cigarette in proximity to the heater blades, and the heater unit defining at least part of a suction flow passage through which ambient air is drawn into contact with the cigarette when a smoker draws on the cigarette positioned in the heater unit. The heater unit is mounted within a partition that positions the heater unit relative to the housing and at least partially defines a bypass flow passage in fluid communication with ambient air surrounding the housing, the partition further defining a flow diverting passage leading from the bypass flow passage to the suction flow passage and through which ambient air is drawn from the bypass flow passage when a smoker puffs on a cigarette inserted in the heater unit opening. A flow sensor is positioned in the flow diverting passage to provide a signal indicative of a smoker taking a puff on the cigarette.

Brush cleaning unit

A brush cleaning unit for a heater fixture of a smoking device includes a holder such as a tube wherein the heater fixture can be washed with a liquid by a movable brush. The tube can include first and second ends, a portion of a key for cooperating with a corresponding portion of the key on the heater fixture for orienting the heater fixture, and an arrangement for preventing the brush from rotating. The brush can be arranged to be axially movable relative to the tube and the heater fixture attached thereto.

A brush cleaning unit for a heater fixture of a smoking device includes a tube having a first end and a second end, the tube including a portion of a key for cooperating with a corresponding portion of the key on a heater fixture for attaching and orienting the heater fixture relative to the tube. The brush cleaning unit also includes a brush attached to the tube. The brush is axially movable relative to the tube and the heater fixture attached thereto. The brush is non-rotatable relative to the tube. A method for cleaning a heater fixture is also disclosed.

A method of manufacturing cigarettes including the steps of establishing a succession of 2-up hollow plugs in alternating relation to 2-up tobacco plugs and wrapping same in a tobacco web and overwrap, severing the resultant continuous rod at mid points of preselected 2-up tobacco plugs and severing again to establish associated pairs of singular tobacco rod plugs, separating the members of associated pairs of tobacco rod plugs and placing 2-up filter tipping plugs therebetween, and subsequently wrapping the interposed 2-up filter tipping plug together with adjacent portions of the singular tobacco rod plugs and severing the resultant tipped structure into individual cigarettes. Also provided are cigarettes constructed in accordance with the novel method.
