As shown in fig. 2, the housing of the machine body 1 has a disc-shaped structure, a universal wheel for steering and a pair of driving wheels are mounted at the bottom of the machine body 1, and three wheels are in a three-point supporting state at the bottom of the machine body 1 to maintain the stability of the machine body 1. The machine body 1 is internally provided with a control terminal, a driving mechanism and various obstacle avoidance and road searching sensors, so that the machine body 1 can automatically avoid obstacles and search for road to run. The disc-shaped shell structure of the machine body 1 can be flexibly shuttled into a complex environment together with the universal wheels.
As shown in fig. 1 and 5, the cleaning mechanism 2 includes a clean water tank 21, a high-pressure water pump 22 and a spray head 23, wherein the clean water tank 21 and the high-pressure water pump 22 are installed inside the machine body 1, the spray head 23 is located at the bottom of the machine body 1, and the clean water tank 21, the high-pressure water pump 22 and the spray head 23 are sequentially communicated through a clean water pipeline 24 to form a water supply channel. The high pressure water pump 22 provides a pressurizing effect to flush the cleaning liquid stored in the cleaning liquid tank 21 from the spray head 23 in a high kinetic energy state, forming a high kinetic energy water column which is sprayed toward the carpet. The water column impacts on the surface of the carpet to remove the garbage and sundries which are mixed in gaps of the carpet fluff, and meanwhile, the water column can also disperse the carpet fluff to clean the region covered by the fluff. Wherein the cleaning liquid can comprise water or liquid with cleaning and decontamination capability, and the user can select different cleaning liquids according to the pollution degree of the carpet.
As shown in fig. 3, in order to improve the cleaning efficiency, in an embodiment, a plurality of spray holes 231 are formed on the spray head 23, each spray hole 231 is communicated with the clean water pipeline 24 connected with the spray head 23, that is, each spray hole 231 is a branch waterway, the high-pressure water pump 22 is pressurized to enable each spray hole 231 to spray high-kinetic energy water column to flush the carpet, the number of spray holes 231 is increased to improve the cleaning area of the carpet in unit time, so that the cleaning effect is finer, more uniform and more comprehensive, and the purpose of improving the cleaning efficiency is further achieved.
Further, as shown in fig. 3, since the area of the carpet washed by the high kinetic energy water jet ejected from each nozzle 231 is limited, in order to avoid the occurrence of a missed washing area due to the excessive distance between two adjacent washing areas, in this embodiment, each nozzle 231 is inclined toward the center line of the machine body 1 in the horizontal plane. Because the direction of the high kinetic energy water column ejected from the nozzle 231 is the same as the direction of the central axis of the nozzle 231, the water columns ejected from each nozzle 231 are concentrated toward the center in a convergent manner, so that the edges of the flushing areas formed by two adjacent water columns are overlapped, and the occurrence of a missed flushing area is avoided.
As shown in fig. 3, in order to make the intervals of the high-kinetic-energy water columns in the flushing area of the carpet surface uniform, when the positions and the inclination angles of the spray holes 231 are set, the spray holes 231 are symmetrically arranged on both sides of the central line of the machine body 1 in the horizontal plane as symmetrical axial directions, each spray hole 231 takes the central line of the machine body 1 in the horizontal plane as a datum line, and the included angle between the central line and the central line of each spray hole 231 is the inclination angle of the spray hole 231. In order from near to far from the central line, the inclination angle of the next nozzle 231 increases by 2.6-3 ° from the inclination angle of the previous nozzle 231 in each adjacent two nozzles 231, that is, the increase angle set by each nozzle 231 is 2.6-3 °. And the increment angles of the spray holes 231 are the same, so that the intervals of the high-kinetic energy water columns in the carpet surface flushing area are equal, wherein the front side and the rear side of the central line are respectively the advancing direction and the retreating direction of the sweeper, and the driving wheels of the sweeper are symmetrically positioned at two sides of the central line. Further, in the present embodiment, the center line is a structural line which is a middle position of the shower head 23 and is perpendicular to the shower head 23.

Thereby ensuring that the high kinetic energy water jets ejected from the orifices 231 are adjacent and that the cleaning zones formed on the carpet are also aligned. It should be noted that, in order to improve the cleaning effect of the high-kinetic energy water columns on the carpet, the installation angle between the central axes of all the spray holes 231 and the ground is 35-45 degrees, so that each high-kinetic energy water column washes the carpet from the oblique side, and each high-kinetic energy water column washes the area formed on the surface of the carpet to be elliptical, and compared with the area of the circle center area formed by vertically washing the surface of the carpet by the high-kinetic energy water columns, the area of the circle center area is larger. And all spray holes 231 have the same included angle with the ground, so that the fluff on the carpet can be flushed to the same side, and the fluff of the carpet can be turned over, washed and guided. The carpet surface layer covered by the fluff can be cleaned, garbage wound or mixed between fluff gaps can be flushed away from the area where the carpet surface layer is located, the effect of removing garbage can be achieved, and the fluff can be straightened, so that friction force is reduced.
It should be noted that, in the present embodiment, the direction of each spray hole 231 is opposite to the moving direction of the machine body 1, that is, the high kinetic energy water column washes towards the rear of the machine body 1, so that the residual garbage and sewage after washing is accumulated behind the machine body 1, so that the corresponding mechanism arranged behind the machine body 1 can recycle the garbage and sewage.
In one embodiment, as shown in fig. 1,2, 4 and 5, the cleaning device of the present invention further comprises a recovery mechanism 3 for recovering the waste and sewage washed by the high kinetic energy water column.

It should be noted that a sensor may be disposed at the filter screen 35 to monitor the amount of newly added garbage at the filter screen 35 in unit time, when the amount of newly added garbage at the filter screen 35 in unit time is smaller than a predetermined value, a signal is excited to prove that the cleanliness of the area is higher, and the control terminal receives the signal to instruct the related driving mechanism and various obstacle avoidance and path finding sensors to operate the machine body 1 to go to other areas for cleaning.
In one embodiment, as shown in fig. 5, to prevent the blower 33 from sucking sewage into the blower 33 during the process of sucking air in the sewage tank 32, a blower chamber sealing plate 36 is provided at the connection of the blower 33 and the sewage tank 32 to partition the installation space of the blower 33 to form a blower chamber. The sealing plate is provided in a turnover or liftable structure to control the air duct communication or separation between the blower 33 and the sewage tank 32. In this embodiment, the fan chamber sealing plate 36 is of a turnover structure, and an electric switch is arranged on one side of the installation position of the fan 33, and the fan chamber sealing plate 36 is commanded to be pushed up by the electric switch through a control terminal in the machine body 1 to communicate the fan 33 with the sewage tank 32, or the electric switch is commanded to be retracted by the control terminal in the machine body 1 to separate the fan 33 from the sewage tank 32, so that the fan 33 is protected from sewage infiltration.
Because the working principle of the fan 33 is that the air in the sewage tank 32 is pumped to the outside, the air hole is arranged at the position of the machine body 1 corresponding to the fan chamber, so that the fan can conveniently send out the air.
As shown in fig. 2, 5 and 6, in order to improve the recycling efficiency of the waste and the sewage due to the different thickness of the fluff on the carpet surface, the recycling mechanism 3 further includes a floating scraper 37 in an embodiment, the floating scraper 37 is provided with a collecting opening 371 communicated with the waste collecting box 31, the floating scraper 37 covers the surface of the carpet and the fluff layer, and suction is formed at the collecting opening 371 by the negative pressure in the sewage tank 32, so that the waste and the sewage in the carpet surface layer and the fluff layer are sucked into the waste collecting box 31 through the collecting opening 371. In order to adapt to the height change of the carpet surface, one side of the floating scraper 37 is connected with the bottom of the machine body 1 in a shaft way through the rotating shaft 372, the effect that the floating scraper 37 can turn around the shaft connection side is achieved, in the advancing process of the machine body 1, the floating scraper 37 turns over and undulates along with the thickness change of the carpet, the state that the collecting port 371 is attached to the carpet is always kept, the negative pressure suction force generated at the collecting port 371 is stronger, and garbage and sewage can be efficiently absorbed. The heel can absorb the water vapor of the cleaned carpet, and the drying speed of the carpet is increased.
