[0033] Please refer to Figures 1 to 6 As shown, one embodiment of this application provides a cleaning vehicle, which includes a vehicle body 10, a suction cup assembly 20, and a suction pipe 30. The suction cup assembly 20 is connected to the vehicle body 10 and extends towards the ground. One end of the suction pipe 30 is connected to a suction mechanism inside the vehicle body 10, and the other end is detachably connected to the suction cup assembly 20. The suction cup assembly 20 has a connected suction port 21 and an air outlet 22. The suction port 21 is located close to the ground, and the air outlet 22 is connected to the suction pipe 30. The suction pipe 30 sucks up debris from the ground through the suction cup assembly 20.

[0034] Specifically, the cleaning vehicle of this embodiment includes a suction pipe 30 and a suction cup assembly 20. One end of the suction pipe 30 is connected to the inside of the vehicle body 10, and the other end is connected to the suction cup assembly 20. The suction pipe 30 and the suction cup assembly 20 are detachably connected. When the suction pipe 30 is detached from the suction cup assembly 20, the operator can directly control the suction pipe 30 to aim at the ground to absorb garbage in corners. The lower end of the suction cup assembly 20 has a suction port 21, and the upper end has an air outlet 22. The suction port 21 and the air outlet 22 are connected. The suction pipe 30 is installed at the air outlet 22 of the suction cup assembly 20 so that the suction pipe 30 can generate suction at the suction port 21 of the suction cup assembly 20, thereby sucking up garbage on the ground. The suction port 21 of the suction cup assembly 20 is always facing the ground, and the suction cup assembly 20 moves with the vehicle body 10. That is, as the vehicle body 10 moves forward, the suction pipe 30 can directly suck up the garbage on the ground through the suction cup assembly 20 without the need for operator intervention.

[0035] When using the cleaning vehicle of this application, the operator first connects the suction pipe 30 to the air outlet 22 of the suction cup assembly 20 and turns on the suction mechanism inside the vehicle body 10 to enable suction from the suction pipe 30. Since the suction cup assembly 20 faces the ground and moves synchronously with the vehicle body 10, the suction pipe 30 can suck up the garbage on the ground through the suction cup assembly 20 as the vehicle body 10 moves forward. The operator only needs to control the direction of the vehicle body 10. When it is necessary to suck up garbage in some corners, the operator can detach the suction pipe 30 from the suction cup assembly 20 and manually operate the suction pipe 30 to suck up the garbage.

[0036] In an optional embodiment, the suction cup assembly 20 includes a mounting bracket 23, an air guide shell 24, and a wind deflector 25. The mounting bracket 23 is mounted on the vehicle body 10, the air guide shell 24 is mounted on the mounting bracket 23, the upper end of the air guide shell 24 is connected to the suction pipe 30, and the wind deflector 25 is mounted on the lower end of the suction shell, surrounding the suction shell and forming an air intake 21 below it.

[0037] Specifically, the suction cup assembly 20 includes a mounting bracket 23, an air guide shell 24 mounted on the mounting bracket 23, and a wind deflector 25 mounted on the lower end of the air guide shell 24. The upper end of the air guide shell 24 is connected to the suction pipe 30, that is, the air outlet 22 is located at the upper end of the air guide shell 24, and the air outlet 22 of the air guide shell 24 is connected to the suction pipe 30. The wind deflector 25 surrounds the lower end of the suction pipe 30 and forms an annular cavity structure. The opening of the annular cavity faces the ground to align with the garbage on the ground. When using this device, the suction pipe 30 is connected to the air outlet 22 at the upper end of the air guide shell 24, and the air guide shell 24 and the wind deflector 25 form a suction port 21. Therefore, when the suction mechanism inside the vehicle body 10 is activated, garbage on the ground can be sucked up. It can be understood that in this embodiment, the suction port 21 is slightly higher than the ground to facilitate the suction of garbage on the ground.

[0038] In some embodiments, the windshield 25 is formed by multiple rubber sheets. The rubber sheets have a certain degree of flexibility. By setting a flexible windshield 25, it is possible to prevent the windshield 25 from getting stuck on the ground during the movement of the vehicle body 10.

[0039] In an optional embodiment, the upper end of the air guide shell 24 includes a mounting post 241 for housing the suction pipe 30. An air outlet 22 is disposed on the mounting post 241. The mounting post 241 is adapted to the end of the suction pipe 30, which is directly sleeved on the mounting post 241 to facilitate the installation and removal of the suction pipe 30 from the air guide shell 24. In some embodiments, an interference fit may be used between the suction pipe 30 and the mounting post 241 to increase the stability of the connection.

[0040] In an optional embodiment, the cleaning vehicle further includes a blower assembly 40 mounted on a mounting bracket 23, the blower assembly 40 being used to blow air from the left and / or right side of the vehicle body 10 outwards from the vehicle body 10.

[0041] Specifically, the mounting frame 23 is U-shaped and includes a left wall 231, a right wall 232, and a connecting wall 233, which connects the left wall 231 and the right wall 232. The left wall 231 is located on the left side of the vehicle body 10, and the right wall 232 is located on the right side of the vehicle body 10. The blowing assembly 40 includes a blower 41 and a connecting pipe 42 connected to each other. The blower 41 generates airflow and transmits the airflow through the connecting pipe to the left wall 231 or the right wall 232 of the mounting frame 23, so as to blow airflow from the left wall 231 or the right wall 232 of the mounting frame 23 outwards from the vehicle body 10, thereby blowing the garbage on the left or right side of the vehicle body 10. In this embodiment, when the vehicle body 10 moves to the side of a wall, the suction cup assembly 20, located below the vehicle body 10, cannot pick up the debris. In this case, the blower assembly 40 blows air from the left wall 231 or right wall 232 of the mounting bracket 23 onto the wall. The air is reflected off the wall, blowing the debris towards the lower part of the vehicle body 10, allowing the suction cup assembly 20 to pick it up. It is understood that when the vehicle body 10 moves near a wall, the operator can also detach the suction pipe 30 from the suction cup assembly 20 and use it to pick up the debris. In a more open area, the blower assembly 40 can blow air to the left or right side of the vehicle body 10 while moving forward, blowing debris from the vicinity of the vehicle body 10 to a relatively distant space. For example, blowing the debris beyond the width of two vehicle bodies 10, reducing the number of times the vehicle body 10 travels back and forth to pick up debris. The blower assembly 40 can also expand the cleaning area of ​​the cleaning vehicle, making it easier for operators to pick up garbage over a larger area with fewer approach steps.

[0042] In some optional embodiments, the angle between the air outlet direction of the blower assembly 40 and the forward direction of the vehicle body 10 is α, where α is in the range of 30°-60°. The blower assembly 40 blows air to both sides of the vehicle body 10 to blow trash on the wall forward, and after reflection from the wall, pushes the trash forward of the vehicle body 10, so that the vehicle body 10 can directly collect the trash via the suction cup assembly 20 while moving forward. In this embodiment, the left or right wall of the mounting bracket has an air guide, one end of the connecting pipe is connected to the air guide, and the other end is connected to the blower. A wind deflector 60 is also provided outside the air guide to control the air outlet angle of the blower assembly.

[0043] In an optional embodiment, the mounting bracket 23 is arranged along the left and right direction of the vehicle body 10, the air guide shell 24 extends along the left and right direction of the vehicle body 10, and the air guide shell 24 is adapted to the width of the vehicle body 10.

[0044] Specifically, the mounting bracket 23 is installed at the front end of the vehicle body 10 and located at the bottom of the vehicle body 10 to be closer to the ground. The mounting bracket 23 is fixed to the bottom of the vehicle body 10 by fasteners. The air guide shell 24 extends along the left and right direction of the vehicle body 10, and the length of the air guide shell 24 is approximately the same as the width of the vehicle body 10, so as to facilitate the vehicle body 10 to pick up garbage on the ground while moving forward. In this embodiment, the vehicle body 10 only needs to move forward once to pick up the garbage for the same section of road, so as to avoid the vehicle body 10 repeatedly moving. It can be understood that during the forward movement of the vehicle body 10, the width that can be cleaned in one go is approximately equal to the width of the vehicle body 10.

[0045] In an optional embodiment, the suction pipe 30 includes a telescopic pipe 31 and a suction pipe 32. One end of the telescopic pipe 31 is connected to the suction mechanism inside the vehicle body 10, and the other end of the telescopic pipe 31 is connected to the suction pipe 32. The suction pipe 32 is detachably connected to the suction cup assembly 20. The telescopic pipe 31 is telescopic, allowing the suction pipe 32 to be extended to a more distant work area, making it easier for workers to collect garbage from further away. The suction mechanism consists of components such as a motor and impeller that generate suction. The suction mechanism is a mature technology and will not be described in detail here.

[0046] The vehicle body 10 is also equipped with a telescopic channel 11, which is used for the extension and storage of the telescopic tube 31. The telescopic tube 31 can be stretched and retracted along the telescopic channel 11 and can be retracted into the telescopic channel 11 to prevent the telescopic tube 31 from being scattered and to maintain the cleanliness of the cleaning vehicle.

[0047] In an optional embodiment, the cleaning vehicle further includes a fixing structure 50, which is mounted on the vehicle body 10 and used to fix the suction pipe 30. The telescopic pipe 31 is telescopic, with one end fixed and the other end (connected to the suction pipe 32) movable. Therefore, the suction pipe 30 is prone to deformation and detachment during vehicle body 10 operation, requiring secondary positioning. This application provides a fixing structure 50 on the vehicle body 10 to fix the suction pipe 30, ensuring that the suction pipe 30 does not deform during vehicle body 10 operation. The fixing structure 50 can be an elastic band or a rotating clamp. It should be noted that the elastic band or rotating clamp can be opened and closed; when the user needs to use the suction pipe 30, the elastic band or rotating clamp is opened to allow the suction pipe 30 to be removed.

[0048] The above description is merely an exemplary embodiment of the present utility model and does not limit the patent scope of the present utility model. Any equivalent structural transformations made based on the technical concept of the present utility model and the contents of the present utility model specification and drawings, or direct / indirect applications in other related technical fields, are included within the patent protection scope of the present utility model.
