[0029] like Figures 1 to 10As shown, this utility model provides an embodiment of a cleaning machine with a three-way valve device, which includes a vertical body 1000, a wastewater tank 3000 detachably mounted on the vertical body 1000, a floor brush seat 2000 with a roller brush body 2200 mounted at the bottom of the vertical body 1000 and movable on a horizontal plane, a cleaning machine motor 4000 located inside the vertical body 1000 and downstream of the wastewater tank 3000, a clean water tank 5000 detachably mounted on the vertical body 1000, a three-way valve device mounted on the floor brush seat 2000, and an accessory connector 6000 detachably connected to the three-way valve device. The accessory connector 6000 is connected to a handheld accessory, which can be used for specialized cleaning of furniture or small carpets.

[0030] The floor brush holder 2000 also includes a floor brush adapter 2300 located between the three-way valve device and the accessory connector 6000, and a nozzle 2600 disposed adjacent to the roller brush body 2200 and downstream of the clean water tank 5000. The floor brush adapter 2300 includes a valve body receiving hole 2320 that accommodates the first water outlet pipe 2424 and corresponds to the water inlet pipe 6040, an adapter air hole 2340 that corresponds to the air inlet pipe 6080 and communicates with the upstream of the wastewater tank 3000, and a mating groove 2360 that engages with the locking member 6090. The roller brush body 2200 rotates about an axis parallel to the horizontal plane to perform rotary cleaning of the horizontal plane.

[0031] The three-way valve assembly includes a hollow valve body 2420, a valve end cap 2440 connected to the valve body 2420, a first outlet pipe 2424 integrally connected to the valve body 2420, an inlet pipe 2428 integrally connected to the valve body 2420, a second outlet pipe 2444 integrally connected to the valve end cap 2440, and a valve stem 2460 located within the valve body 2420 and capable of reciprocating motion. The valve body 2420 has a valve body cavity 2422 that at least partially accommodates the valve stem 2460. The inlet pipe 2428 is located between the first outlet pipe 2424 and the second outlet pipe 2444, wherein the center direction of the first outlet pipe 2424 is perpendicular to the horizontal plane. The valve stem 2460 is hollow and includes a valve stem outlet 2464 at the top, a valve stem inlet 2466 below the valve stem outlet 2464, a grille portion 2467 located below the valve stem inlet 2466 and spaced apart from it, and a valve stem tail end 2468 located below the grille portion 2467.
