The invention discloses a novel automatic water injector which mainly consists of a floater, a metal contact, a water storage tank, a spring, an armature, an electromagnet, a metal contactor, switches, a motor with a water pump, a power supply and a lead, wherein the floater is connected with the metal contact and is placed in the water storage tank; the spring is connected with the armature; the electromagnet is arranged at the lower end of the armature; two ends of the armature are connected with the power supply; the switch is connected with the motor with the water pump; the motor is connected with the metal contactor; the other components are connected through the lead. Therefore, the automatic water injector is manufactured. When the automatic water injector is used, the switch is closed firstly, after the switch is closed, the water pump starts working, the water level is increased, when the floater rises to the metal contactor, a circuit on the left side starts working, the electromagnet is magnetized, the armature is pulled down to close another switch, the motor stops working, and water is stopped being injected; when the water level is reduced till the metal contactor is dissociated from the switch, the circuit stops working, and the electromagnet is nonmagnetic; therefore, the purpose of automatic water injection is achieved when the switches are closed and opened repeatedly.
