In a general impression, water is a conductor and there is a significant risk of electrical contact. In fact, any object has resistance, so that the device can be transformed into an appliance meeting the needs of people on the premise of meeting the economical requirement, thereby benefiting the mankind. This is the case with "electricity-insulating walls". When the electric water heater is powered on, water in the heating inner container can be attenuated by the resistance of the water when passing through the electricity isolating wall to achieve the purpose of isolating electricity even if the water passes through the electricity isolating wall, so that the voltage of the water inlet end and the water outlet end of the water heater is almost zero and the extremely weak current below 0.02mA/kw is achieved. The electricity-proof wall is used for preventing the electricity leakage possibly generated by the electric water heater and preventing the safety threat to a bather caused by the electrification of a ground wire or a water pipe by adopting the electricity-proof wall technology. Therefore, the water heater adopts the technology of the electricity-isolating wall, so that the bathing safety of people can be fully ensured.
However, the existing electricity-proof wall usually seals the upper port of the water inlet pipe, and the water inlet hole is formed in the pipe wall of the upper part of the water inlet pipe, when the water heater enters water, cold water flow flows into the inner container of the water heater from the water inlet hole, under the action of water pressure, the cold water flow can impact original hot water in the inner container and quickly diffuse, and great disturbance can be generated to a water layer in the diffusion process of the cold water flow, so that the water temperature in the inner container is quickly reduced, and the output efficiency of the hot water is reduced.

Detailed Description
The present invention will be further described with reference to the accompanying drawings. An electricity-proof wall of an electric water heater comprises a water inlet device main body 1, wherein a water guide pipe 2 extends upwards from the upper end of the water inlet device main body 1, a butt joint seat 3 is arranged at the bottom of the water guide pipe 2, a connecting pipe 4 is sleeved on the surface of the butt joint seat 3, the top of the connecting pipe 4 is sealed, and the inside of the connecting pipe 4 is communicated with the top of the water guide pipe 2; the water flow stabilizing device is characterized in that a plurality of drain holes 41 are formed in the cylindrical surface of the lower end of the connecting pipe 4, a flow stabilizing pipe 5 is sleeved outside the connecting pipe 4, a buffer cavity 6 is arranged between the bottom of the flow stabilizing pipe 5 and the connecting pipe 4, and water flow discharged from the drain holes 41 enters the buffer cavity 6 and then is discharged from the bottom of the flow stabilizing pipe 5.
The diameter of the top end of the flow stabilizing pipe 5 is smaller than that of the lower end.
The water discharge holes 41 of the connecting pipe 4 are distributed on the cylindrical surface of the connecting pipe in a circumferential array.
The water discharge hole 41 of the connecting pipe 4 is arranged in a groove shape.
The cylindrical surface of the flow stabilizing tube 5 is provided with an air guide hole 51, and the position of the air guide hole 51 is positioned at the upper end of the water drainage hole 41.
The air guide hole 51 is arranged in a circular hole shape.
The working principle is as follows: in the present case, go into water ware main part upper end and upwards extend and have the aqueduct, the bottom of aqueduct is provided with the butt joint seat, and the surface cover of butt joint seat is equipped with the connecting pipe. Wherein, a plurality of drain holes are evenly arrayed on the circumference of the cylindrical surface at the lower end of the connecting pipe and penetrate through the connecting pipe. When cold water enters from the water inlet device main body and flows out from the upper end of the water guide pipe, the cold water flows downwards along the pipe body of the connecting pipe all the time due to the sleeving of the connecting pipe, and is discharged through the water discharge hole. Wherein, the drain hole plays a role of buffering water flow for the first time. When water flow is discharged from the water discharge hole, the water flow enters the buffer cavity 6 between the connecting pipe and the flow stabilizing pipe, the buffer cavity 6 plays a second buffer role on the water flow discharged from the water discharge hole, and finally the water flow is discharged from the bottom of the flow stabilizing pipe 5, so that a third buffer role is played.
