As shown in fig. 16, 17 and 18, in this embodiment, the cleaning water jet holes 38 are provided in the first flow path 10 at a position close to the wet mop cleaning portion 13, so that the water jet cleaning is performed in cooperation with the suction of the suction source, and thus, the entire first flow path 10 can be cleaned well by the fewer cleaning water jet holes 38. The cleaning water jet holes 38 are plural and arranged circumferentially around the first flow path 10, which enables better and more efficient cleaning. A third flow channel 12 is arranged between the clean water barrel 22 and the wet mop cleaning part 13, the third flow channel 12 is provided with two branches, namely a first branch and a second branch 39 and 40, the first branch 39 is used for conveying water of the third flow channel 12 to the wet mop cleaning part 13, and the second branch 40 is used for conveying water of the third flow channel 12 to the cleaning water spraying holes 38, so that the arrangement structure is convenient, and the better arrangement of the cleaning water spraying holes 38 is facilitated.

The third flow channel 12, the first branch 39 and the second branch 40 are all water delivery hoses, the water inlet end of each water delivery hose is connected with the clear water barrel 22, the water outlet end of the first branch 39 is connected with the water outlet hole positioned on one side of the wet mop cleaning part 13, and the water outlet end of the second branch 40 is connected with the cleaning water spraying hole 38.

The washing water jetting holes 38 are provided in four and are uniformly arranged along the circumferential direction of the first flow path 10. The water flow from the second branch 40 is divided into four paths by the distributor 43, each path connecting one of the washing spouts 38, as shown in fig. 16 and 18, fig. 18 being a cross-sectional view showing three of the washing spouts 38.

The main body of the first flow passage 10 is a telescopic bellows, and if a pipeline with a smooth inner wall is adopted, the flow of a gas-liquid mixture is facilitated, dirt and dirt are not easy to store, and the cleaning is facilitated, so that the reduction of wrinkles is facilitated for cleaning and sanitation.

As shown in fig. 16, the first branch 39 is provided with a first water pump 41, the second branch 40 is provided with a second water pump 42, so that the control can be separated, the different water spraying requirements of the wet mop cleaning part 13 and the cleaning water spraying hole 38 can be met, the flexibility is high, meanwhile, the first water pump 41 and the second water pump 42 are also used as control valves, the first water pump 41 can independently control the on-off of the first branch 39 and the third flow channel 12, the second water pump 42 can independently control the on-off of the second branch 40 and the third flow channel 12, in addition, no additional control valve is needed, the pressurization control is integrated, and the structure is simplified.

The water spray angle of the cleaning water spray holes 38 may be varied and may be determined by design according to the first flow passage 10, water pressure, etc. The spray pattern of the cleaning water spray holes 38 may be water jets, water mist, or other patterns.

As shown in fig. 11, 12 and 13, the wet mop cleaning part 13 adopts a rolling brush structure, when cleaning the floor, the floor is mopped on the one hand, and the suction source sucks in dirt through the flow passage, and if water exists on the floor, the gas-liquid mixture is sucked, or when the wet mop cleaning part 13 is the wet mop cleaning part 13 which is wetted, and the wet mop cleaning part 13 is pressed by the scraper, the scraper squeezes out the dirt at the same time of mopping the floor, and when the suction source sucks, the gas-liquid mixture is sucked.

In order to continuously wet the wet mop cleaning part 13, a water injection nozzle is arranged on the circumference of the wet mop cleaning part 13 and connected with a clean water barrel 22 through a third flow channel 12, in this example, the clean water barrel 22 is arranged coaxially with the gas-liquid separation structure and is positioned on the upper side of the gas-liquid separation structure.

The water delivery hose is provided with a water shortage detection sensor 17 which can detect in a non-contact manner with water, the water shortage detection sensor 17 detects whether water flows through or not, for example, a capacitive sensor is arranged at the rear end of the water shortage detection sensor 17, the water pump 16 is arranged at the rear end of the water shortage detection sensor 17, and signals obtained through detection of the water shortage detection sensor 17 can enable the wet mop cleaning part 13 and the suction source to stop working in time or prompt a user of information such as water shortage, water addition and water existence.
