The cleaning and adsorption mechanism comprises four support plates 11 fixedly connected to the lower side of the sweeping robot body 1, a roller 12 rotatably sleeved between the two support plates 11, and an adsorption layer 13 bonded to the outer side of the roller 12. The drying mechanism includes a heating box 14 fixedly connected to the right side of the sweeping robot body 1, four exhaust pipes 16 connected to the lower side of the heating box 14, a plurality of heating tubes 15 fixedly installed inside the lower side of the heating box 14 and an exhaust fan 17 embedded inside the upper side of the heating box 14.

[0029] Among them, the driving mechanism includes four driving motors 23 fixedly installed inside the sweeping robot body 1, a rotating shaft 19 fixedly connected to the output end of the driving motor 23, a bearing 24 fixedly connected to the lower side of the rotating shaft 19, a connecting shaft 20 sleeved on the inner wall of the bearing 24 and a roller 21 sleeved on both ends of the connecting shaft 20, a controller 10 is embedded and installed on the left end of the upper side of the sweeping robot body 1, four pressure sensors 22 electrically connected to the output end of the controller 10 are embedded and connected on the surface of the sweeping robot body 1, the outer diameter of the adsorption layer 13 is the same as the outer diameter of the roller 21, a dustproof net 18 is fixedly clamped on the right end of the upper side of the sweeping robot body 1, and the dustproof net 18 is clamped on the upper end face of the exhaust fan 17, the end of the exhaust fan 17 close to the dustproof net 18 is the air inlet and the end close to the heating pipe 15 is the exhaust port, the four exhaust pipes 16 are arranged equidistantly in the horizontal direction, and the exhaust pipe 16 is vertically connected to the lower side of the heating box 14, and the left side of the drain pipe 5 is integrally connected with a downward inclined drainage port.

[0030] It should be noted that the adsorption layer 13 is a sponge sheet, which is detachably adhered and fixed to the outside of the roller 12. The adsorption layer 13 needs to be torn off from the surface of the roller 12 regularly, and a new adsorption layer 13 is replaced and adhered to the surface of the roller 12 to adsorb the cleaning liquid discharged from the drain pipe 5 and the dust or fine garbage on the ground. The output end of the controller 10 is electrically connected to the pressure sensor 22, the drive motor 23, the solenoid valve 4, the exhaust fan 17, the roller 21 and the heating tube 15 output ends respectively, so as to better control the coordination between the various structures in the sweeping robot body 1.

[0031] Embodiment 2:

[0032] See also Figure 1-3 On the basis of the first embodiment, an anti-collision mechanism is provided on the outside of the sweeping robot body 1, and the anti-collision mechanism includes a plurality of connecting rods 6 fixedly connected to the outer surface of the sweeping robot body 1, a spring 7 sleeved on the outside of the connecting rod 6 and a protective plate 8 fixedly connected to the side of the connecting rod 6 away from the sweeping robot body 1, one side of the protective plate 8 is vertically connected to two connecting rods 6 at the same time to form a group of four groups, and each group of protective plates 8 is respectively fixed on four surfaces of the surface of the sweeping robot body 1, and a groove 9 matching the connecting rod 6 is opened inside the sweeping robot body 1.

[0033] By adopting the above technical scheme, when the protective plate 8 of the sweeping robot body 1 away from the connecting rod 6 contacts other objects during movement, the spring 7 squeezes and changes the contact pressure sensor 22 of the protective plate 8 to remind the sweeping robot body 1 to change direction. At the same time, when the object collides with the protective plate 8, the spring 7 also has a certain buffering purpose, thereby achieving the anti-collision function.

[0034] The working principle of the above embodiment is:

The sweeping robot body 1 turns on the exhaust fan 17 and the heating pipe 15 at a later stage. The heating pipe 15 generates heat energy and combines with the exhaust fan 17 to absorb the external gas, which is filtered by the dustproof net 18 and combined with the heat energy, and then discharged to the ground from the exhaust pipe 16, so as to quickly dry the cleaning liquid that is not completely adsorbed by the adsorption layer 13 and has a certain amount of residue, which can effectively Reducing the slippery condition of the ground can also ensure the disinfection and sterilization function of the ground. When the protective plate 8 on one side of the sweeping robot body 1 contacts an external object and continues to move, the protective plate 8 will compress the connecting rod 6 through the spring 7 and move it into the groove 9, so that the protective plate 8 contacts the bearing 24 on the surface of the sweeping robot body 1 to trigger the controller 10, and then transmit it to the drive motor 23.
