Disclosed is a switchable dual-passage cleaning nozzle, comprising a nozzle handle (2), wherein the nozzle handle (2) is mounted on a rotating shaft; a lifting rod (3) is mounted in the nozzle handle (2) and is clamped and fixed through a left valve seat (4) and a right valve seat (11); a top end of the lifting rod (3) cooperates with a bearing follower (16) located outside the nozzle handle (2) to conduct linkage; a main flow guiding hole is provided in the nozzle handle at one side of the lifting rod (3) in a spray direction, a first sub flow guiding hole A and a second sub flow guiding hole B are respectively provided in the nozzle handle at the other side of the lifting rod in the spray direction; the flow passages of the first sub flow guiding hole A and the second sub flow guiding hole B are parallel to each other, so as to form dual water outlet passages; dual flow passages are correspondingly provided in the lifting rod in the spray direction; and the abutting join between the main flow guiding hole and the first sub flow guiding hole A or the second sub flow guiding hole B is achieved through the upward and downward displacement of the lifting rod (3), so as to switch the two sub flow guiding holes between connection and disconnection. The cleaning nozzle can achieve quick switching of the nozzle merely by controlling the angle of a rotating shaft, thereby saving on tool changing time and improving cleaning efficiency. |
