Fluid dispenser having a discharge head

A fluid dispenser, in particular for discharging pharmaceutical or cosmetic fluids, having the following features:

• a. the fluid dispenser has a base unit having a fluid accumulator for receiving fluid before the discharge procedure, and
• b. the fluid dispenser has a discharge head which is provided for securing to the base unit, and
• c. the fluid dispenser possesses a pump device, which can be actuated by a relative translative movement of the discharge head with respect to the base unit and conveys fluid from the fluid accumulator into the discharge head, or the fluid accumulator is formed as a pressure accumulator and the fluid dispenser possesses a valve device, which can be actuated by a relative translative movement of the discharge head with respect to the base unit and conveys fluid from the fluid accumulator into the discharge head, and
• d. the discharge head has a housing, which is preferably displaceable with respect to the base unit for the purpose of actuating the fluid dispenser, and
• e. the discharge head has a fluid inlet, through which fluid to be discharged can make its way from the fluid accumulator into the discharge head, and
• f. the discharge head has a discharge opening, through which the fluid can be delivered into a surrounding atmosphere, and
• g. a swirling chamber having at least one eccentrically leading inlet channel is provided between the fluid inlet and the discharge opening so that inflowing fluid is provided with a swirl which brings about the formation of a spray stream as it exits the discharge opening,
• h. the swirling chamber can be switched between at least a first and a second configuration by changing the geometry of walls of the swirling chamber and/or the at least one inlet channel, and
• i. the discharge head has a handle for manually switching between the configurations.
