As shown in fig. 1, the scrub apparatus includes a vessel 110, a plurality of first nozzles 101 and a plurality of second nozzles 102, a first manifold 140 and a second manifold 150. The container 110 is configured to contain a liquid, and the plurality of first nozzles 101 and the plurality of second nozzles 102 are each configured to eject a liquid. A first manifold 140 connects the vessel 110 and the plurality of first nozzles 101 to deliver the liquid in the vessel 110 to the plurality of first nozzles 101. A second manifold 150 connects the vessel 110 and the plurality of second nozzles 102 to deliver the liquid in the vessel 110 to the plurality of second nozzles 102. The pressure of the liquid in the first manifold 140 is greater than the pressure of the liquid in the second manifold 150.

For example, the first nozzle may be a high pressure nozzle and the second nozzle may be a low pressure nozzle, i.e. the operating pressure of the first nozzle is greater than the operating pressure of the second nozzle. The high pressure liquid in the first manifold may be injected at a higher pressure after being delivered to the first nozzle and the low pressure liquid in the first manifold may be injected at a lower pressure after being delivered to the second nozzle. The first manifold and the first nozzle are suitable for occasions requiring high-pressure operation, such as high-pressure washing operation on road surfaces, road shoulders, garbage bins and the like. The second manifold and the second nozzle are suitable for use in a situation where low-pressure operation is required, and may be used for, for example, flushing operation or dust-fall operation in the road surface width direction. It should be noted that the "first nozzle" and the "second nozzle" are only for distinguishing nozzles with different operating pressures, but are not intended to limit the specific type of the nozzles. The specific type of first nozzle included in each of the following assemblies/devices may be the same or different, for example, the first nozzle may be a fan nozzle, a cone nozzle, a spray nozzle, or the like. Likewise, the specific type of second nozzle included in each of the following assemblies/devices may be the same or different, e.g., the second nozzle may be a fan nozzle, a cone nozzle, a spray nozzle, etc.

For example, the first container 211 is located at the front side of the second container 212, and the first container 211 may be located between the cab 301 and the second container 212. It should be noted that, in the embodiments of the present disclosure, the terms "front side", "rear side", "left side", "right side" and the like may be used with respect to the vehicle body, the front side may be understood as a side closer to the vehicle head, the rear side may be understood as a side closer to the vehicle tail, and the left side and the right side are two sides in the width direction of the vehicle body, respectively. In the figure, the X direction is the longitudinal direction of the vehicle body, the Y direction is the width direction of the vehicle body, and the Z direction is the height direction of the vehicle body.

The outer side plate of the first container 211 may be a corrugated structure, and the inner side plate may be provided with a swash plate to reduce or eliminate the impact of the wave of the fresh water on the box body. The top of the first container 211 may be provided with a filler opening, e.g. circular, for quick filling with fresh water. For example, the second container 212 may include two side tanks 212A respectively located at left and right sides of the vehicle body and a bottom tank 212B communicating the two side tanks 212A, and the overall cross-section of the two side tanks 212A and the bottom tank 212B may be U-shaped. A filth case 220 (i.e., a trash case) may be disposed between the two side water tanks of the second container 212, and the filth case 220 is located at an upper side of the bottom water tank 212B. As shown in fig. 3, the filth case 220 includes a cavity with a slope for storing sewage and garbage. Through setting up two storage container around to utilize low pressure manifold intercommunication these two containers, can increase storage space and make spatial layout more reasonable. The two containers are both at normal pressure, and normal pressure pipelines for communicating the two containers converge into the low pressure manifold, so that the pipelines can be reasonably arranged, and the space utilization rate is improved.

The first nozzles of the middle flushing assembly 233 are configured to spray liquid in a first direction, and the first nozzles of the two side flushing assemblies are respectively configured to spray liquid in both sides of the first direction.

For example, the washing and dirt-suctioning device 230 further includes a mounting frame 234 and a fixing frame 235, the mounting frame 234 is connected to the vehicle body chassis through the fixing frame 235, and the two side washing assemblies 232, the middle washing assembly 233 and the first dirt suction pipe 231 are connected to the mounting frame 234. The two side wash units 232 are located on both sides in the width direction of the vehicle body, respectively. The middle flushing assembly 233 is located between the two side flushing assemblies 232 in the Y-axis direction, and the middle flushing assembly 233 is located at the rear sides of the two side flushing assemblies 232 in the X-axis direction.

For example, each side washing assembly 232 includes a spraying member 2321 and a rotating frame 2322, the spraying member 2321 includes at least one first nozzle, the rotating frame 2322 is connected with the mounting frame 234, and the washing member 2321 can be rotated relative to the mounting frame 234 by the rotating frame 2333 to adjust the direction of the liquid spray.

Each first nozzle of the middle flush assembly 233 may spray water toward the ground, e.g., downward in the Z-axis. The side wash assemblies 232 on the left side in fig. 4 spray obliquely, for example, in the lower left direction, and the side wash assemblies on the right side spray obliquely, for example, in the lower right direction.

For example, the washing and sweeping apparatus may further include a front flushing device 273, the front flushing device 273 being located at a side of the washing and dirt-suctioning device 230 near the first container, i.e., the front flushing device 273 is located at a front side of the washing and dirt-suctioning device 230, e.g., the front flushing device 273 may be installed at a vehicle head position. The front hedging device 273 includes two second nozzles having injection ports arranged to face each other. The second nozzle included in the front opposing device 273 may be an opposing nozzle, and two opposing nozzles are disposed opposite to each other to perform a washing function in the width direction of the road surface.

Fig. 7 is a schematic structural view of another washing and sweeping device according to at least one embodiment of the present disclosure. As shown in fig. 2, 3 and 7, for example, the scrubbing apparatus further includes a fan 281 and a dust removing device 282. The fan 281 may be disposed in the fan box 283. The blower 281 is configured to drive the air in the dirt box 220 to be exhausted, for example, the top of the blower box 283 may be provided with an air suction opening 2831, and the air inside the dirt box 220 tends to be exhausted by forming a negative pressure inside the dirt box 220 through the air suction opening 2831 during the operation of the blower 281.

The dust extraction device 282 includes a dust extraction chamber 2821 and a plurality of filter cartridges 2822 positioned within the dust extraction chamber 2821, wherein the filter cartridges 2822 filter out dust particles from the gas.

For example, the washing and sweeping apparatus further includes a switching device configured to allow the air discharged from the dirt tank 220 to enter the dust removing device 282, or allow the air discharged from the dirt tank 220 to directly enter the fan 281 without passing through the dust removing device 282. For example, the scrub device can have two modes of operation: a dry-sweeping mode and a scrubbing mode. Under the washing mode of sweeping, parts such as first manifold, second manifold, first nozzle and second nozzle can be in operating condition to spray liquid to ground, and then reach the effect of clean ground and dust fall. Under the mode of dry sweeping, parts such as the first manifold, the second manifold, the first nozzle and the second nozzle can not work, namely the washing and sweeping device does not spray liquid to the ground, so that the problem of icing on the ground in cold environments such as winter is avoided. In the scrubbing mode, the dust content of the gas sucked into the dirt tank is small due to the cleaning and dust falling effects of the liquid. On the contrary, in the dry sweeping mode, the dust content of the air sucked into the filth tank is large, and therefore, in the dry sweeping mode, the air in the filth tank needs to be further dedusted and then discharged to avoid secondary pollution to the air. For example, in a cleaning mode, the switching device can guide the air to directly enter the air suction opening after being discharged from the sewage tank, and then the air is discharged by the fan; in the dry-sweeping mode, the switching device can direct the air discharged from the dirt box to enter the dust removing device 282, and the dust removed air enters the air suction opening and is discharged by the fan.
