Abstract: An electronic cigarette has a mouthpiece portion and a power supply portion. The mouthpiece portion has an atomizer seating to receive an atomizer. An atomizer lock is located in the atomizer seating and is moveable between an open position and a locked position. An ejection mechanism with a biased ejection surface is moveable within the atomizer seating and is biased toward an extended position. The ejection mechanism is moved to a retracted position when an atomizer is introduced to the atomizer seating; the atomizer lock grips the atomizer to hold it in a fixed position. The atomizer is ejected from the atomizer seat when the atomizer lock is opened.

Abstract: An electronic cigarette includes a mouthpiece portion having a refillable liquid store having a sealable opening, a valve closing member and an atomizer receiving section. The valve closing member is configured to seal the opening and control a flow of liquid from the liquid store to the atomizer receiving section. The flow of liquid to an atomizer is enabled when an atomizer is present in the atomizer receiving section. The atomizer is connectable to an inner sleeve at the atomizer seating in a power supply portion. The atomizer is moveable toward the valve closing member such that the valve closing member is urged toward the open position, and away from the valve closing member such that the valve closing member cannot be urged toward the open position, by axially moving the inner sleeve in relation to an outer sleeve with an actuator.

Abstract: A liquid refill system includes a liquid reservoir portion of an electronic cigarette and a refilling bottle. The refillable reservoir portion has a refillable liquid store, an axially moveable valve closing member and a first biasing member. The refillable liquid store has an opening in a bottom portion and the axially moveable valve closing member is moveable between an open position and a closed position. The first biasing member is configured to bias the axially moveable valve closing member towards the closed position to seal the liquid opening. The axially moveable valve closing member is moved into the open position when the refillable reservoir portion is engaged with the refilling bottle. The refilling bottle has a liquid tank 92 and a liquid transfer arrangement configured to transfer liquid from the liquid tank to the refillable liquid store in the in the electronic cigarette.

Abstract: An electronic cigarette and a mouthpiece portion of an electronic cigarette are provided. The mouthpiece portion has a liquid store, an atomizer-receiving portion, a vapour outlet and a vapour flow tube. The liquid store has a liquid opening in a bottom portion thereof; the mouthpiece portion has an axially moveable closing member which is movable between an open position and a closed position. The axially moveable closing member is biased towards the closed position to seal the liquid opening. The closing member is urged towards the open position when an atomizer is present in the atomizer receiving portion.

Abstract: A wearable sitting posture assisting device includes at least one leg unit featuring at least one knee joint and featuring at least one locking unit for the knee joint; includes at least one second leg unit featuring at least one second knee joint and featuring at least one second locking unit; and includes at least one actuation unit featuring at least one manually operable actuation element for mechanically controlling the locking unit and/or the second locking unit.
