[0002] With the advancement of rural environmental improvement and beautiful rural construction, as well as the increasing attention paid to environmental sanitation in cities, traditional manual cleaning methods can no longer meet the growing cleaning needs. Electric sweepers, with their high efficiency, environmental protection and labor-saving characteristics, have gradually become a new choice for cleaning work. The continuous development of battery technology and intelligent control technology has gradually improved the performance of electric sweepers. At the same time, advanced sensors and artificial intelligence technologies have been applied to sweepers, making them more intelligent and able to achieve efficient navigation, cleaning and automatic charging functions. Traditional fuel sweepers face environmental pressure due to the emission of harmful gases and particulate matter. Electric four-wheel sweepers, as zero-emission cleaning tools, have actively responded to environmental protection requirements and become an important choice to replace traditional sweepers; Existing electric four-wheel sweepers have certain requirements for the working environment. The mixture of stagnant water and dust and dirt will seriously affect the vacuum performance of the sweeper. At the same time, the sweeper is large in size and has low flexibility. It is inefficient when working in narrow scenes with many obstacles. It is easy to collide with obstacles and cause equipment damage. The sweeper's ability to handle stagnant water, heavy garbage and sticky garbage is weak, resulting in reduced cleaning effect and cleaning efficiency of the sweeper.

[0003] 1. Patent document CN109322267B discloses a sweeper. The above patent realizes the transportation of cleaned garbage to a larger space by transfer, so as to achieve the technical effect of convenient use, saving time and improving cleaning efficiency. However, the above patent cannot realize the function of cleaning sticky garbage.

[0004] 2. Patent document CN106702929B discloses a classification sweeper. The above patent realizes that a large particle collection device is set in front of the main cleaning brush. The large particle collection device is provided with a collection box to collect large particle impurities, and an inclined arc-shaped transition connection groove is provided on one side of the collection box as a channel for lifting large particle impurities. The large particle impurities are lifted to the opening of the collection box by a rotating impeller, and the collection is fast and convenient. However, the above patent cannot realize the function of cleaning the working environment of the sweeper.

[0005] 3. Patent document CN110820646B discloses a field-type sweeper. The above patent realizes a method in which a garbage clamping mechanism clamps garbage instead of a vacuum cleaner, which reduces the noise of the sweeper and avoids the loss of function due to blockage. However, the above patent cannot realize the function of detecting the working environment of the sweeper.

[0006] 4. Patent document CN106759003B discloses a sweeper. The above patent achieves the elimination of multiple expensive hydraulic cylinders, reduces the overall weight of the vehicle body, and is easy to maintain. The passive interference part is connected to the active interference part, allowing the garbage collection component to move upward as a whole following the drive belt and / or the fixed belt, and the garbage collection component leaves the ground, thereby releasing plastic bags and other films. Due to the setting of two rotating sweeping wheels, the garbage will first be gathered in the middle, and then the rotary cleaning mechanism will sweep the garbage into the garbage collection component, thereby solving the edge effect. However, the above patent cannot realize the function of the sweeper to clean uneven roads.

[0007] In summary, the above patents cannot realize the function of cleaning sticky garbage, cannot realize the function of cleaning the working environment of the sweeper, cannot realize the function of detecting the working environment of the sweeper, and cannot realize the function of sweeping the uneven road surface by the sweeper, resulting in poor effect of cleaning sticky garbage, serious wear of equipment, sticky garbage cannot be recycled, internal equipment of the sweeper is blocked, performance is reduced, secondary pollution is caused, cleaning efficiency is low, safety hazards are increased, maintenance costs are increased, and driving safety problems; To this end, the present application proposes an electric four-wheel sweeper with self-cleaning function and a method of using the same, which can realize the functions of cleaning sticky garbage, cleaning the working environment of the sweeper, detecting the working environment of the sweeper, and cleaning uneven roads.

[0030] Working principle: the dust concentration is measured by the dust sensor 30, the gas concentration information is detected by the gas sensor 31, and the information is transmitted to the controller 8. After comparison with the safety value, it is determined whether the gas in the current environment is suitable for the equipment to work. If it is not suitable for the sweeper to work, the controller 8 controls the dust removal motor 32 to drive the fan 33 to rotate to absorb the external air of the sweeper, and then discharge it after filtering through the filter 34 to remove dust and harmful gases in the air. At the same time, the controller 8 controls the flushing module to spray water during the sweeping process of the sweeper; During the operation of the sweeper, the visual sensor 29 extracts road information and transmits the information to the controller 8. The controller 8 compares the information transmitted by the visual sensor 29 with the information in the database to determine the type of garbage that needs to be cleaned. When sticky garbage such as silt appears, the controller 8 controls the lifting unit 15 through the cleaning motor 19 to drive the second rotating shaft 20 and the stirring rod 21 to descend.
