Referring to fig. 5, the water leakage detecting terminal 3 includes an insulating body 3-1 and a pair of metal sheets 3-2 injection-molded on the insulating body 3-1; the two metal sheets 3-2 are arranged at intervals; the insulation body 3-1 is integrally formed with false alarm preventing bosses 3-3 corresponding to the metal sheets 3-2, and each metal sheet 3-2 is arranged on the corresponding false alarm preventing boss 3-3 and is higher than the upper surface of the insulation body 3-1.
During assembly, the water leakage detection terminal 3 is arranged on the water collecting tank 2 at the bottom of the water heater shell 1 in a penetrating manner from outside to inside, and the false alarm prevention boss 3-3 and the metal sheet 3-2 are both protruded into the water heater shell 1; the water leakage detection terminal 3 is arranged from the outside, so that the installation and the maintenance are convenient; meanwhile, the false alarm prevention boss 3-3 is provided with a false alarm prevention function, and a small amount of condensed water drops down to prevent an alarm.
In this embodiment, the insulating body 3-1 is preferably integrally formed with a mounting and fixing hole 3-4, and the water collecting tank 2 is preferably provided with a through hole corresponding to the mounting and fixing hole 3-4, so that the water leakage detecting terminal 3 and the water heater housing 1 are conveniently mounted and fixed.
Further preferably, a shrink-proof groove 3-5 is formed on the insulating body 3-1 and located between the two false alarm preventing bosses 3-3. As for the insulating body 3-1 in the utility model, as the insulating body is an injection molding part, the material has thermal expansion and cold contraction, the size of the plastic part is reduced after high-temperature injection molding and cooling, and the thicker the material is, the more the material is shrunk. Therefore, by arranging the shrink-proof groove 3-5 between the two false alarm-proof bosses 3-3, deformation of the injection molding part caused by thermal expansion and cold shrinkage can be effectively avoided, and the water leakage detection terminal is ensured to conform to the design size and be assembled smoothly.
Referring to fig. 6 and 7, a positioning hole 3-2-1 is formed in the metal sheet 3-2, and a metal terminal 4 is inserted into the metal sheet 3-2 and elastically limited with the positioning hole 3-2-1 through a corresponding protrusion; the metal terminals are used for connecting wires.

The common standard component can be that one end is a slot, the other end is a wire jack structure, the slot is in plug-in fit with the metal sheet, the wire jack has an extrusion deformation locking function, and the wire is extruded and locked after being inserted into the wire jack.
Referring to fig. 8, the water leakage detection structure of the gas water heater provided in this embodiment has the following working principle: the metal terminal 4 inserted on the water leakage detection terminal 3 is connected with the main controller 6 by a lead 5; when no water leakage occurs, the two metal sheets 3-2 are separated by an insulator and air, and a circuit connected with the main controller 6 is open; when water leaks in the water heater, after the water level passes through the false alarm prevention boss 3-3, the water touches the metal sheets 3-2 on the water leakage detection terminal 3, the two metal sheets 3-2 are conducted to form a loop, current passes through the loop, and the main controller 6 detects water leakage. The false alarm preventing boss 3-3 on the insulator 3-1 is arranged, when a small amount of condensed water generated during the operation of the water heater drops on the bottom shell, the water level is lower than the false alarm preventing boss 3-3, the two metal sheets 3-2 cannot be conducted, and false alarm is prevented.
