For the detection of the split machine water tank, the detection procedure is a station corresponding to the tail end of the final assembly and provided with the temperature sensing bulb, and at the moment, the split machine water tank is not connected with the body of the water heater, so that the split machine water tank does not have power supply capacity and needs to be supplied with power by a detection device. For the water tank of the all-in-one machine, the detection process is synchronously performed when the whole machine operates and detects, and the all-in-one machine has power supply capacity, so that when the electronic anode 7 is detected, the butt terminal 3 of the detection device is not connected with the electronic anode 7, but the connecting wire 42 led out of the indicating component 4 is directly connected with the anode output end 71 and the cathode output end 72 of the electronic anode 7. After the wiring is completed, whether the problem of wiring error exists in the electronic anode 7 is judged by observing the on-off condition of the indicator lamp 41 in the indicator assembly 4.

Further, the indication component 4 has no direct connection relation with the housing 1, the power supply component 2 and the connection terminal 3 in structure, so in principle, the indication component 4 does not need to be integrated with the above components and can be completely and independently arranged. However, in order to maintain the integrity and ease of use of the test device, in this embodiment, the indicator assembly 4 is preferably integrated into the housing 1.
In one embodiment, the connector further comprises a first connector 421 and a second connector 421 respectively connected to the ends of the two connecting lines 42;

Specifically, when the positive output end 71 and the negative output end 72 of the electronic anode 7 do not have a columnar protruding structure on the outer surface of the inner container 6, it is difficult to connect the electronic anode 7 through an electric clamp; therefore, when the positive output end 71 and the negative output end 72 of the electron anode 7 are made of ferromagnetic metal or relative alloy and do not have a protrusion for connecting a power supply clamp, a magnetic connector can be used to quickly connect the corresponding electrodes through magnetic force adsorption.
