Claim:
An ear irrigation device for the removal of earwax, which integrates a fluid injector assembly formed by a body defining a container for fluid which is loaded into the container and discharged therefrom by means of a rod and plunger assembly arranged with hermetic sealing in said container, so as to divide the container into a front chamber for the fluid and a rear chamber, and enable bidirectional linear sliding of the rod and plunger assembly through an inside of the container between a retracted position and an extended position, and vice versa, an actuating element to move said rod and plunger assembly to said retracted position, a retaining element to retain said rod and plunger assembly in said retracted position, a nozzle portion, through which the fluid of the front chamber of the container is discharged by ejection, and a handgrip with a trigger controlling at least the retaining element to release the rod and plunger assembly retained by the latter and to allow the rod plunger assembly to move towards said extended position, wherein: the rod and plunger assembly includes a hollow rod having an end that is distal from said plunger and is attached to a part acting as a guide which slides inside said rear chamber of the container, the hollow rod of the plunger is hollow and is provided for housing, when the rod and plunger assembly moves, a fixed axial guide element starting from an end part for closing the container, and a spring is provided coaxial to the fixed axial guide element, said spring being housed inside the hollow rod.
