A tube-end device for fire extinguishment which jets and sprays pressurized and fed fire-extinguishing water, which is water, seawater, or aqueous fire-extinguishing agent from a tube end, comprising: a main body having the tube end on the distal end side and formed integrally with a frame having a gripping unit, and made of an insulating material; a tube main body having a water hose connecting opening on the proximal end side and housed inside the main body and made of a conductive material; a nozzle unit disposed on the distal end side of the tube main body and inside the tube end, and emitting the fire-extinguishing water; an induction electrode unit having a ring-shape and disposed at an outside position that is in the opening side relative to the nozzle unit; a water-side electrode unit disposed at a position of the interior of the tube main body which is an electrically-conductive cylindrical member, and supported and fixed to the tube main body by an insulator in contact with the fire-extinguishing water on the side of the water hose opening of the tube main body; a voltage applying unit which is incorporated in the gripping unit and connected to the induction electrode unit and water-side electrode unit, and applying an external electric field, which is generated by applying a voltage between the induction electrode unit and the water-side electrode unit, to the fire-extinguishing water in the process of jetting from the nozzle unit, electrically charging jetted particles, and emitting the particles; and a power supply unit which is incorporated in the gripping unit and supplying DC power to the voltage applying unit; and a voltage application switch disposed on the gripping unit and connected to the voltage applying unit, and applying a voltage by the voltage applying unit between the induction electrode unit and the water-side electrode unit. a main body having the tube end on the distal end side and formed integrally with a frame having a gripping unit, and made of an insulating material; a tube main body having a water hose connecting opening on the proximal end side and housed inside the main body and made of a conductive material; a nozzle unit disposed on the distal end side of the tube main body and inside the tube end, and emitting the fire-extinguishing water; an induction electrode unit having a ring-shape and disposed at an outside position that is in the opening side relative to the nozzle unit; a water-side electrode unit disposed at a position of the interior of the tube main body which is an electrically-conductive cylindrical member, and supported and fixed to the tube main body by an insulator in contact with the fire-extinguishing water on the side of the water hose opening of the tube main body; a voltage applying unit which is incorporated in the gripping unit and connected to the induction electrode unit and water-side electrode unit, and applying an external electric field, which is generated by applying a voltage between the induction electrode unit and the water-side electrode unit, to the fire-extinguishing water in the process of jetting from the nozzle unit, electrically charging jetted particles, and emitting the particles; and a power supply unit which is incorporated in the gripping unit and supplying DC power to the voltage applying unit; and a voltage application switch disposed on the gripping unit and connected to the voltage applying unit, and applying a voltage by the voltage applying unit between the induction electrode unit and the water-side electrode unit.
