Then, the motor 910 drives the pulley 2 908 to rotate, thereby driving the two sets of pulleys 1 907 to rotate, and driving one set of cleaning wheels 700 to rotate. Then, through the meshing action of gear 1 911 and gear 2 912, the other set of cleaning wheels 700 is driven to rotate, so that the two sets of cleaning wheels 700 rotate in opposite directions.

[0040] The working principle of the present invention is:

[0041] When in use, the traveling wheel 500 and the cleaning wheel 700 move on the ground, driving the housing 100 to move on the ground; the air inside the ash hopper 201 is sucked by the air inlet end of the negative pressure pump 207 in cooperation with the connecting pipe 206, so that the air at the bottom of the housing 100 passes through the suction pipe 202 and enters the interior of the ash hopper 201, and the dust in the air is filtered by the mesh cover 204 and the filter cotton 205, so that the dust is trapped inside the ash hopper 201 and accumulated in the baffle 203;

[0042] At the same time, the motor 910 drives the pulley 2 908 to rotate, and cooperates with the transmission effect of the transmission belt 909 to drive the two sets of pulleys 1 907 to rotate, and drives one set of cleaning wheels 700 to rotate, and then drives the other set of cleaning wheels 700 to rotate through the meshing effect of gear 1 911 and gear 2 912, so that the two sets of cleaning wheels 700 rotate in opposite directions, sweeping the dust on the ground, and making the flying dust fly toward the suction pipe 202, and cooperate with the suction effect of the suction pipe 202 on the air, so that the dust enters the inside of the ash hopper 201;

[0043] Then, the water in the water storage tank 401 is sucked by the submersible pump 403, and the water is transported to the inside 406 through the water distribution pipe 404 and the nozzle 405, so that the 406 is kept moist. When the 406 slides on the ground, the cleaned ground is mopped;

[0044] Then, the air is introduced into the annular flow channel 301 through the exhaust end of the negative pressure pump 207 in conjunction with the second connecting pipe 302, and then the air is blown toward the floor after mopping through the air outlet 303, thereby accelerating the evaporation efficiency of the water stains left after mopping.

[0045] In the process of cleaning the ground, the output end of the cylinder 607 is extended, and the connection between the two sets of slide seats 604 and the fixed plate 606 is cooperated, so that the two sets of slide seats 604 are driven to move leftward along the slide rail 605, and then the connection between the L-shaped plate 603 and the rotating arm 602 is cooperated, so that the dirt-shoveling plate 601 is deflected downward and fits on the ground; then the housing 100 moves along the ground, and the sugar cubes and heavy dirt adhering to the ground are shoveled to the top of the dirt-shoveling plate 601;

[0046] When the slide 604 slides to the left, the slide 604 is located at the side wall of the inclined groove 906 to squeeze the slide post 905, driving the two groups of slide posts 905 to approach each other, and cooperating with the connecting function of the sealing plate 901, the distance between the two groups of cleaning wheels 700 is reduced, so that the bristles of the cleaning wheel 700 are close to the sugar cubes and heavy dirt adhered to the ground, and then the cleaning wheel 700 rotates, and the bristles on the cleaning wheel 700 apply a thrust toward the shoveling plate 601 to the dirt, further ensuring that the dirt is smoothly shoveled to the top of the shoveling plate 601.

[0047] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
