Atomizer ejection mechanism for aerosol inhaler

An electronic cigarette comprising a mouthpiece portion and a power supply portion, wherein the power supply portion comprises:

• an atomizer seating configured to receive an atomizer,
• an atomizer lock located in the atomizer seating and movable between an open position and a locked position, wherein the atomizer lock is configured to selectively grip the atomizer when the atomizer is received in the atomizer seating and release the atomizer from the atomizer seating, the atomizer lock including an outer sleeve and an inner sleeve, which is rotatable in relation to the outer sleeve, and an actuator configured to selectively rotate the inner sleeve relative to the outer sleeve in order to grip or release the atomizer wherein the atomizer is configured to rotate in unison with the inner sleeve, and
• an ejection mechanism comprising a biased ejection surface movable within the atomizer seating between a retracted position and an extended position, wherein the ejection surface is biased towards the extended position,
• wherein the ejection mechanism is movable into the retracted position when an atomizer is introduced into the atomizer seating, and the atomizer lock is configured to grip the atomizer and hold the atomizer in a fixed position, and wherein the atomizer is ejected from the atomizer seating when the atomizer lock is opened.
