Abstract
A device (100) for firing a projectile at a target body, in particular a fluid projectile or solid projectile, comprises a hand-held unit (100) for firing the projectile, the hand-held unit (100) comprises a propulsion drive (114) for accelerating the projectile and a distance measuring device (112) for measuring a distance between the hand-held unit (100) and the target body. The device (100) also comprises an energy store (120) for operating the propulsion drive (114), the propulsion drive (114) comprising a control unit (115), whereby the propulsion (114) is controllable in dependence on the distance measured.

Device for firing a fluid projectile at a target body, comprising:
- a hand-held unit for firing the projectile, the hand-held unit including
- a pump propulsion drive for accelerating the projectile, and
- a distance measuring device for measuring a distance between the hand-held unit and the target body;
- an energy store for operating the propulsion drive;
- a control unit configured to control the pump based on the distance measured;
- a nozzle pivotable in a plane parallel to a cross-sectional area of the hand-held unit along a firing axis;
- and
- a servo configured to pivot the nozzle based on the distance measured and a power output of the pump.
Method for operating a device for firing a fluid projectile at a target body, the device comprising a pivotable output nozzle, a hand-held unit for firing a projectile, and also including a propulsion drive for accelerating the projectile and a distance measuring device, the device also comprising an energy store for operating the propulsion drive, wherein the propulsion drive is a pump and comprises a control unit, the method comprising
- measuring a distance between the hand-held unit and the target body;
- controlling a power output of the pump propulsion drive in dependence on the distance measured;
- pivoting the nozzle by means of a servo based on the distance measured and the power output of the pump;
- and
- firing the fluid from the pivoted nozzle.
