As a further improvement of the technical scheme, the water outlet hole is positioned at the lower section of the sleeve, and the water inlet channel is communicated with the water outlet hole after being subjected to inflection for more than three times in the sleeve. The water flows into the sleeve from the water inlet hole and flows out from the water outlet hole positioned at the lower section of the sleeve after being bent for more than three times, the length of the sleeve can be greatly utilized by the path, the water channel is prolonged, the water resistance length can be further improved, and the aim of better electric shock prevention is achieved.
As a further improvement of the above technical solution, with the position of the base relative to the sleeve being in a downward direction, the sleeve includes:
the pipe orifice at the upper end of the outer pipe is sealed, the pipe orifice at the lower end of the outer pipe is in butt joint with the base, and the water outlet hole is positioned at the lower section of the outer pipe;
The inner pipe is sleeved in the outer pipe, an upper gap is reserved between the upper end of the inner pipe and a pipe orifice sealed at the upper end of the outer pipe, a side gap is reserved between the outer peripheral wall of the inner pipe and the inner peripheral wall of the outer pipe, an inner channel extending along the axial direction of the inner pipe is arranged inside the inner pipe, the inner channel is provided with an inner channel inlet and an inner channel outlet, the inner channel inlet is arranged at the lower end of the inner pipe and used as the water inlet hole, the inner channel outlet is arranged at the upper end of the inner pipe, and the inner channel is provided with at least two inflection points in the inner pipe.

The base 100, the plug 400, various pipe fittings and gaskets are all made of insulating materials, the base 100 is provided with an installation part connected with the outside, and the base 100 and the outside can be connected by adopting a fixing mode such as a metal threaded insert.
The inner channel provided in the inner tube body 301 has various embodiments. In some embodiments, the following implementations may be employed: in the inner tube body 301, a plurality of webs 302 are provided, and of two sides of each web 302 which are opposite to each other, one side is combined with the central axis of the inner tube body 301, and the other side is connected with the inner wall of the inner tube body 301, thereby dividing the inner portion of the inner tube body 301 into a plurality of inner cavities. Specifically, these inner chambers are divided into a water inlet chamber 3011 having a lower end communicating with the lower notch, a water outlet chamber 3013 having an upper end communicating with the upper notch, and an intermediate chamber 3012 communicating together an upper end of the water inlet chamber 3011 and a lower end of the water outlet chamber 3013.
Still further, the number of the intermediate chambers 3012 is one, that is, the inner chamber is divided into three chambers of an inlet chamber 3011, an intermediate chamber 3012 and an outlet chamber 3013, and the cross sections of the three chambers are basically fan-shaped. The communication port between the water inlet chamber 3011 and the intermediate chamber 3012 is at the uppermost end of the web between the two chambers, and the communication port between the intermediate chamber 3012 and the water outlet chamber 3013 is at the lowermost end of the web between the two chambers. So that the water flow enters from the water inlet hole, passes through the lower notch of the lower sealing gasket 502, enters from the lowest end of the water inlet chamber 3011, flows upward until after passing through the uppermost end of the water inlet chamber 3011, turns over the web 302 between the water inlet chamber 3011 and the middle chamber 3012, turns down into the middle chamber 3012, flows all the way down until reaching the lowest end of the middle chamber 3012, turns over the web 302 between the middle chamber 3012 and the water outlet chamber 3013, turns up into the water outlet chamber 3013, flows all the way up until reaching the uppermost end of the water outlet chamber 3013, passes through the upper notch of the upper sealing gasket 501 and the plug 400, enters into the gap left between the upper end of the outer tube 200 and the plug 400, namely, the upper gap, overflows and turns down again, flows down along the gap left between the outer peripheral walls of the outer tube 200 and the inner tube 300, namely, turns up to flow all the side gaps, and finally flows all the way around from the plurality of hydrophobic holes 201 of the outer tube 200. Therefore, in this embodiment, the water flow passes through three inflection before flowing out from the water drain hole 201, and the path length of the water flow is three times of the axial length of the whole sleeve, so that the design can greatly prolong the water resistance length in a limited space and increase the electric shock preventing effect.
