Abstract:
1. A liquid ejection device comprising: an inhaling port; an ejection head for ejecting a liquid to be inhaled by a user through the inhaling port; a first sensor having at least one of a pressure sensor and a flow meter, for outputting a first signal responsive to detection of a first phenomenon by the first sensor; a second sensor for detecting an action of the user relating to inhalation and for outputting a second signal responsive to detection of the action, the second sensor being different from the first sensor; and a determining portion for determining an operation of ejecting the liquid of the ejection head in response to both the first signal and the second signal, wherein the determining portion is constructed to respond to a first state, in which the second sensor outputs the second signal while the first sensor is outputting the first signal, and to respond to a second state, in which the first sensor outputs the first signal while the second sensor is outputting the second signal, and responds to each of those states by enabling ejection of the liquid from the ejection head.
