Existing pole assembly connectors or fittings cannot simultaneously ensure smooth flow channel connection and stable and safe electrical connection.

[0067] Based on this, the present invention provides a pole end connector sleeve, a pole assembly, and a floor scrubber, which will be described in detail below through specific embodiments.

[0068] Example 1

This not only achieves a stable and safe electrical connection and a smooth flow channel connection, but also ensures a reliable mechanical connection between the rod end fitting 100B and the hinge device 20 through the combination of mutual insertion and fitting. This effectively avoids the risk of leakage caused by liquid spillage. Furthermore, the connection method is simple and can achieve quick assembly and disassembly.

[0073] In an optional implementation, refer to Figure 1 , Figure 3 , Figure 6 and Figure 7As shown, the rod end docking sleeve 100B further includes a second water inlet connector 100B5 and a second water outlet connector 100B6 disposed at the end of the docking sleeve body 100B2 away from the connecting groove 100B21.
