[0030] like Figures 1 to 4 As shown, the cleaning device with dust collection and cleaning functions of this embodiment includes a mounting plate 1 installed on the sweeper, and a dust collection structure 2 and a cleaning structure 3 are installed on the mounting plate 1. The dust collection structure 2 includes a negative pressure unit and a suction pipe 21 arranged on both sides of the mounting plate 1. The suction port at the lower end of the suction pipe 21 extends to the bottom of the mounting plate 1, the upper end of the suction pipe 21 is connected to the garbage bin, the negative pressure unit is connected to the garbage bin, and the cleaning structure 3 includes a spray rod 31 arranged on the mounting plate 1 and a water supply unit connected to the spray rod 31.

[0031] The mounting plate 1 is mounted on the vehicle's frame via a lifting cylinder and two connecting rods. The lifting cylinder moves the mounting plate 1 up and down, and the two connecting rods enhance the device's robustness and stability. A negative pressure unit and a water supply unit are mounted on the vehicle's frame. The negative pressure unit is connected to the top of the trash bin, while the suction pipe 21 is connected to the bottom. The negative pressure unit creates a negative pressure inside the trash bin, drawing road debris through the suction port and into the bin. The water supply unit provides a high-pressure water source for the spray bar 31, which then sprays high-pressure water to clean the road surface. This cleaning device integrates the dust collection structure 2 and the cleaning structure 3 on a single mounting plate 1, significantly simplifying the product's structure, reducing its overall size, and making maintenance easier. During operation, the dust collection structure 2 and the cleaning structure 3 work together, flushing road debris into the suction port at the bottom of the suction pipe 21, where it is then absorbed by the suction pipe 21, ensuring efficient cleaning in complex environments.

[0032] In this embodiment, the spray rod 31 includes a main spray rod 311 and two auxiliary spray rods 312. The main spray rod 311 is installed along the length direction of the mounting plate 1, and an auxiliary spray rod 312 is installed at each end of the mounting plate 1 along the length direction. The main spray rod 311 and the auxiliary spray rod 312 are both connected to the water supply unit. The main spray rod 311 and the auxiliary spray rod 312 are both connected and provided with a nozzle 32. The nozzle 32 on the main spray rod 311 extends to the bottom of the mounting plate 1, and the nozzle 32 on the main spray rod 311 is inclined toward the air suction port.

[0033] The cleaning device is provided with three spray bars which can spray and clean simultaneously or individually. The auxiliary spray bar 312 can clean the road surface or curb on both sides, thus increasing the cleaning function.

[0034] In this embodiment, the auxiliary spray rod 312 is mounted on the mounting plate 1 via a mounting frame 4. A rotation driving structure 5 for driving the auxiliary spray rod 312 to rotate in a horizontal direction is mounted on the mounting frame 4.

[0035] Specifically, the rotary drive structure 5 includes a rotating seat 51, a fixed connecting seat 52, a movable connecting seat 53 and a linear telescopic member 54. The rotating seat 51 and the fixed connecting seat 52 are respectively arranged at both ends of the mounting frame 4. The movable connecting seat 53 is fixedly connected to the rotating seat 51, the fixed end of the linear telescopic member 54 is hinged to the fixed connecting seat 52, and the telescopic end of the linear telescopic member 54 is hinged to the movable connecting seat 53. One end of the auxiliary spray rod 312 is detachably mounted on the rotating seat 51, and a bearing sleeve is provided inside the rotating seat 51, which is movably mounted on the top of one side of the mounting frame 4 away from the main spray rod 311 through the bearing sleeve (the rotating seat 51 is a prior art and will not be described here one by one).

[0036] The horizontal angles of the two auxiliary spray booms 312 are adjustable. During operation, the linear telescopic member 54 is activated, and the telescopic end of the linear telescopic member 54 extends, pushing the two auxiliary spray booms 312 and the rotating base 51 to rotate together. This allows the two auxiliary spray booms 312 to be spread apart, significantly increasing the cleaning area and improving cleaning efficiency while also facilitating curb cleaning. When idle, the telescopic end of the linear telescopic member 54 retracts, pushing the two auxiliary spray booms 312 and the rotating base 51 to rotate in the opposite direction, allowing the two auxiliary spray booms 312 to be stowed, significantly saving space. Because the two auxiliary spray booms 312 are driven by two different linear telescopic members 54, they can be independently extended and operated.

[0037] In this embodiment, the linear telescopic member 54 is any one of an electric push rod, an air cylinder and an oil cylinder.

[0038] In this embodiment, the negative pressure unit is a centrifugal fan, and the suction pipe 21 and the centrifugal fan are both connected to the garbage bin through a bellows.

[0039] In this embodiment, the water supply unit includes a water tank and a water pump. The water tank is connected to the water pump input, and the water pump output is connected to the main spray boom 311 and the two auxiliary spray booms 312. Specifically, each main spray boom 311 and the two auxiliary spray booms 312 correspond to different water pumps. Thus, by controlling the corresponding water pump, the main spray boom 311 or one of the auxiliary spray booms 312 can be activated individually, or the main spray boom 311 and both auxiliary spray booms 312 can be activated simultaneously.

[0040] In this embodiment, a guide plate 6 matching the air suction pipe 21 is provided at the bottom of the mounting plate 1 .

[0041] The guide plate 6 is designed according to wind fluid mechanics, so that the air suction port can form a hurricane, thereby improving the problem that the suction source of the existing technology is not strong enough and it is difficult to effectively suck in large or wet garbage.

[0042] In this embodiment, a running wheel 7 is provided on the outside of the mounting plate 1 , and a height adjustment structure 8 for adjusting the height of the running wheel 7 is provided between the running wheel 7 and the mounting plate 1 .

[0043] In this embodiment, the height adjustment structure 8 includes a slide groove 81, an adjusting bolt 82, an adjusting plate 83, a "7"-shaped bracket 84, a connecting bolt and a nut, which are opened on the side wall of the mounting plate 1. The walking wheel 7 is movably installed on the outside of the adjusting plate 83, one end of the connecting bolt is connected to the inner side of the adjusting plate 83, and the other end of the connecting bolt passes through the slide groove 81 to connect the nut. The adjusting bolt 82 is fixedly installed on the mounting plate 1 through the "7"-shaped bracket 84, and the bottom of the adjusting bolt 82 abuts against the top of the adjusting plate 83.

[0044] When the traveling wheel 7 is worn after working for a long time, the adjusting bolt 82 is rotated, and the adjusting plate 83 pushes the connecting bolt in reverse to slide along the slide groove 81, so that the height of the mounting plate 1 from the ground can be adjusted. If the mounting plate 1 is too low from the ground, it will affect the air intake of the air suction port. If the mounting plate 1 is too high from the ground, it will lead to insufficient suction. By designing the height adjustment structure 8, the dust suction effect of the dust suction structure 2 can be optimized.

[0045] This cleaning device can be provided with an interface for an external atomizing nozzle on the wall of the suction pipe 21. The spray sprayed by the atomizing nozzle can moisten the inside of the trash can, play a role in dust reduction, and prevent the centrifugal fan from bringing dust to the external environment, thereby achieving an environmental protection effect. This cleaning device can also be provided with a space for accommodating sensors on the wall of the suction pipe 21. This sensor includes a dust concentration sensor or a wind speed sensor, etc., to monitor the dust concentration or wind speed inside the suction pipe 21 in real time.

[0046] Except for the technical features described in the specification, the remaining technical features are known to those skilled in the art.

[0047] In the description of this specification, the description with reference to the terms "one embodiment", "some embodiments", "example", "specific example", or "some examples" means that the specific features, structures, materials or characteristics described in conjunction with the embodiment or example are included in at least one embodiment or example of the present invention. In this specification, the schematic representations of the above terms do not necessarily refer to the same embodiment or example. Moreover, the specific features, structures, materials or characteristics described can be combined in any one or more embodiments or examples in a suitable manner. In addition, those skilled in the art can combine and combine different embodiments or examples described in this specification and features of different embodiments or examples without contradiction.
