Device for inhalation synchronized dispensing of a fluid product

An inhalation-synchronized fluid product dispenser device comprising a body (10) provided with a mouthpiece (400), a product reservoir (100) containing a fluid product and a propellant gas being mounted to slide axially relative to said body (10), a metering valve (200), comprising a valve member (210) movable between a rest position and an actuation position, being assembled on said reservoir (100) for selectively dispensing the fluid product on each actuation, said device further comprising:

• a blocking element (500) that is movable and/or deformable between a blocking position in which said metering valve (200) cannot be actuated, and an actuation position in which said metering valve (200), can be actuated,
• a trigger element (600) that is movable and/or deformable between a locking position in which the trigger element blocks said blocking element (500) in the blocking position, and a release position wherein the trigger element does not block said blocking element (500),
• an inhalation-controlled trigger system comprising an inhalation-sensitive member (60) that is deformable and/or movable under the effect of inhaling, said inhalation-sensitive member (60) cooperating with said trigger element (600), such that when said inhalation-sensitive member (60) is deformed and/or moved, said inhalation-sensitive member moves and/or deforms said trigger element (600) towards the release position, thus making it possible to move and/or deform said blocking element (500) from the blocking position towards the actuation position, and
• an actuating member (800) that is movable between a rest position and an actuation position under the effect of a spring (850), said actuating member (800) cooperating with said blocking element (500) such that in blocking position said blocking element (500), said blocking element (500) prevents an axial movement of said actuating member (800), and in actuation position said blocking element (500), said blocking element (500) makes it possible to move said actuating member (800) axially,
• said device comprising an automatic valve release system, which automatically returns said valve member (210) from said metering valve (200) towards the rest position after actuation of the metering valve, independently of the position of said actuating member (800).
