Fluid-product dispenser

A fluid dispenser comprising:

• a reservoir containing air and a fluid;
• a dispenser head that is provided with a dispenser orifice for dispensing the fluid;
• a dip tube that conveys the fluid from the reservoir to the dispenser head;
• a pusher that is axially movable over a determined stroke;
• an electric pump that delivers air into the reservoir so as to force the fluid through the dip tube as far as the dispenser head, the electric pump being actuated by the pusher;
• a battery unit;
• and
• a fluid outlet valve that is arranged upstream from the dispenser orifice for selectively interrupting the feed to the dispenser head, the outlet valve being actuated by the pushe, the pusher occupying a high rest position that corresponds to a closed state of the outlet valve and a low depressed position that corresponds to an open state of the outlet valve;
• wherein:
• all of the air coming from the electric pump is delivered into the reservoir;
• the electric pump is activated by the pusher as soon as it leaves its high rest position, and the outlet valve is opened only in the proximity of the low depressed position, such that the electric pump is electrically powered well before the outlet valve is opened, thereby creating an increase in pressure in the reservoir before the outlet valve is opened;
• and
• the electric pump delivers air into the reservoir with an increase in pressure that is less than 1 Bar.
