DETAILED DESCRIPTION

[0041] The present application is further described in detail below in conjunction with the accompanying drawings.

[0042] The embodiment of the present application discloses a water flow medium circulation structure with anti-electricity function.

[0043] Embodiment 1:

[0044] Reference Figure 1 The water flow medium flow structure with anti-electricity function includes a pipe body 1, a spiral core 2 is arranged in the pipe body 1, and the spiral core 2 and the pipe body 1 are embedded. Specifically, the inner wall of the pipe body 1 is located at the spiral core 2 to form a conical surface, and the spiral core 2 and the pipe body 1 are interference-fitted. The spiral core 2 is spiral-shaped. When the spiral core 2 is interference-fitted with the pipe body 1, it is equivalent to a threaded connection, which can effectively ensure the stability of the spiral core 2 and facilitate the disassembly of the spiral core 2.

[0045] It should be noted that the pipe body 1 can be set as a water outlet pipe or a water inlet pipe. Whether it is set as a water outlet pipe or a water inlet pipe, the taper of the pipe body 1 gradually decreases with the direction of the water flow. And when the water flow medium circulation structure is set at both the water inlet pipe and the water outlet pipe, the anti-electrical protection performance will be better. Of course, it can also be a water inlet pipe or a water outlet pipe alone, and a good anti-electrical effect can be achieved.

[0046] The implementation principle of a water flow medium circulation structure with anti-electricity function in an embodiment of the present application is: when in use, the water flows through the spiral core 2, which effectively extends the flow distance of the water flow, thereby helping the water flow to increase resistance, and can weaken the current passing through the water under the condition of unchanged voltage to achieve the function of an anti-electricity wall.

The stability of the spiral core 2 can be effectively improved. A first sealing ring is provided between the limiting plate 31 and the shaft of the spiral core 2, and a second sealing ring is provided between the limiting cover 34 and the shaft of the spiral core 2.
