<p>Disclosed is a rotational connector, comprising a core body (10) and a housing (20) by which the core body is sheathed, the housing (20) being relatively movable with respect to the core body (10), with an annular groove formed between the core body (10) and the housing (20), the annular groove being in communication with the outside of the rotational connector via a first channel (21) in the housing (20) and a second channel (14) in the core body (10), wherein the annular groove comprises a first annular groove (11), a second annular groove (12) and a separation groove (13) provided between the first annular groove (11) and the second annular groove (12), the insulation groove (13) being in communication with the outside of the housing (20). An environmental sanitation vehicle comprises the abovementioned rotational connector. In the present invention, providing the separation groove (13) between the core body (10) and the housing (20) causes the liquid leaked from the first annular groove (11) or the second annular groove (12) to flow into the separation groove (13) so as to solve the problem that the liquid in the first annular groove (11) and the liquid in the second annular groove (12) flow into each other.</p> |
