The device comprises a chamber () provided with an inlet () and an outlet (); a piston () inside the chamber (), the movement of which causes the exit of the substance; and a motor () with an output shaft () that drives the motion of said piston () when it receives a signal from a sensor; and transmission means that transmit the drive movement from the motor () to said piston (); characterised in that said transmission means comprise: a worm gear () rotationally attached to the output shaft () of the motor (); a first transmission element () connected to said piston (); and a second transmission element () connected to said worm gear () and to said first transmission element (). The device enables small dimensions compared to conventional devices.
