Definitions
- Some vapour generating devices generate a vapour or aerosol from a vaporisable liquid, for example using a heater coil which applies heat to a liquid held in a wick in order to vaporise the liquid.
- Spitting of liquid can occur when liquid builds up on the heater coil and instead of the liquid being fully vaporised, large droplets are ejected into the air stream and inhaled by the user. This is often felt by hot liquid reaching the consumer’s oral cavity, which can be an unpleasant experience. Larger puffs by the user are more likely to result in spitting due to the higher air velocity carrying droplets to the user’s mouth. Furthermore the larger force pulls on the liquid in the reservoir and thus oversaturates the wick and heater coil, leading to subsequent spitting events.
- Each one of the first and second baffles may be movable to obstruct more than half of the width of the bore.
- the first and second baffles may be movable so that in combination the first and second baffles obstruct less than the full width of the bore such as to allow a direct line of sight along the bore between the mouthpiece and the heater.
- One of the first and second baffles may be movable to obstruct more than half of the width of the bore and the other of the first and second baffles may be movable to obstruct less than half of the width of the bore.
- each drop Ld1 , Ld2 may have a diameter of about 0.1 mm
- the size of the lateral gap may be chosen to achieve a desired balance between the suction characteristics and the liquid blocking capability of the device. It will be understood that the gap between the inner ends of the baffles represents a restriction in the bore through which the vapour will pass.
- the cross-sectional area of this restriction is defined by a flow plane which extends between the inner ends of the baffles.
- the flow plane may lie along the longitudinal axis or may be inclined with respect to the longitudinal axis, depending upon the extent to which each one of the baffles extends into the bore. For example, in the case that each of the baffles extends across the bore exactly to the longitudinal axis, the flow plane will lie along the longitudinal axis.
- each baffle comprises a generally flexible sheet which is connected to the inner surface of the wall of the tubular body.
- the baffle sheet In the absence of the suction force, the baffle sheet will hang substantially parallel with the longitudinal axis, i.e. vertically. Under the suction force, the baffle sheet will be deflected such as to extend into the bore as has been described herein above.
- the deflected sheet may be substantially flat when deflected, or may be curved or curled.
Abstract
Un dispositif de génération de vapeur (10) comprend : un corps tubulaire (12) comprenant un alésage (14) et ayant un axe longitudinal (Z) ; un dispositif de chauffage (26) conçu pour vaporiser un liquide (L) ; un embout buccal (16) situé au niveau d'une extrémité de l'alésage (14) et conçu pour qu'un utilisateur applique une force d'aspiration (F) pour aspirer le liquide vaporisé (V) le long de l'alésage (14) depuis le dispositif de chauffage (26) jusqu'à l'embout buccal (16) ; et des premier et second déflecteurs (28, 30) situés dans l'alésage (14) entre le dispositif de chauffage (26) et l'embout buccal (16). Les premier et second déflecteurs (28, 30) sont décalés l'un par rapport à l'autre autour de l'axe longitudinal (Z) et décalés l'un par rapport à l'autre le long de l'axe longitudinal (Z). Chacun des premier et second déflecteurs (28, 30) est mobile par la force d'aspiration (F) pour obstruer partiellement la largeur de l'alésage (14), ce qui amène le liquide vaporisé (V) à suivre une voie sinueuse autour des premier et second déflecteurs (28, 30) vers l'embout buccal (16) et bloque le passage de gouttes de liquide non vaporisé (Ld1, Ld2) vers l'embout buccal (16).
