Detailed Description
The present invention will be further described with reference to the accompanying drawings. An improved structure of an electricity-proof wall of an electric water heater is characterized in that: the water inlet device comprises a water inlet device body 1, wherein a water guide pipe 2 extends upwards from the upper end of the water inlet device 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, and the inside of the connecting pipe 4 is communicated with the top of the water guide pipe 2; a plurality of drain holes 41 are arranged on the cylindrical surface of the connecting pipe 4, and at least two groups of drain holes are arranged; the connecting pipe 4 is further sleeved with a flow stabilizing pipe 5, the top of the flow stabilizing pipe 5 is sealed, a buffer cavity 6 is formed between the inner wall of the flow stabilizing pipe 5 and the outer wall of the connecting pipe, and water flow discharged from the water discharge hole 41 enters the buffer cavity 6 and then is discharged from the bottom of the flow stabilizing pipe 5.
The two groups of drain holes are respectively arranged near the upper end and the lower end of the connecting pipe.
The two groups of drain holes are arranged in the middle and the lower part of the connecting pipe.
The cylindrical surface of the flow stabilizing tube 5 is provided with a diversion hole 51.
The diversion hole 51 is arranged near the bottom of the flow stabilizing pipe 5.
The middle cylindrical surface of the connecting pipe 4 is provided with an inward-concave flow restricting ring 42, and the flow restricting ring 42 is positioned between the upper and lower groups of water discharging holes 41.
The inner wall of the restrictor ring 42 is not in contact with the outer wall of the water conduit.
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 of the connecting pipe and penetrate through the connecting pipe. Wherein, the upper and lower two groups of drain holes are respectively arranged near the upper and lower ends of 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 due to the sleeving of the connecting pipe and is discharged through the upper and lower groups of water discharging holes. 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.
