DETAILED DESCRIPTION

[0032] The embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present invention, and should not be construed as limiting the present invention.

[0033] Combination Figure 1 and Figure 2According to the embodiment of the utility model, the suction pipe assembly 100 of the washing and sweeping vehicle includes a suction pipe 10, a mounting seat 20, a cover plate 30 and a driving member 40. An air flow channel may be provided in the suction pipe 10. The mounting seat 20 is connected to the suction pipe 10 and is provided with a cavity connected to the suction pipe 10. The cover plate 30 is arranged in the cavity and is rotatably connected to the mounting seat 20. The driving member 40 is transmission-connected with the cover plate 30 and is used to drive the cover plate 30 to open and close the suction pipe 10. When the driving member 40 works, it drives the cover plate 30 to rotate relative to the mounting seat 20 to open and close the suction pipe 10. When the cover plate 30 opens the suction pipe 10, the cavity of the mounting seat 20 is connected to the air flow channel in the suction pipe 10. When the cover plate 30 closes the suction pipe 10, the air flow channel of the suction pipe 10 is closed.

[0034] Specifically, the cleaning and sweeping vehicle may include a suction nozzle device and a garbage bin, and the suction pipe assembly 100 may be configured to connect the suction nozzle device and the garbage bin. When the cleaning and sweeping vehicle is working, the fan rotates to generate negative pressure in the garbage bin, and the garbage and sewage on the ground enter the suction nozzle device and settle in the garbage bin through the suction pipe 10. By setting the driving member 40 to drive the cover plate 30, when the cover plate 30 opens the suction pipe 10, the air flow channel in the suction pipe 10 is opened, and the suction nozzle device can be connected with the garbage bin, so that the garbage and sewage on the ground can be sucked into the garbage bin through the suction nozzle device. When the driving member 40 drives the cover plate 30 to close the suction pipe 10, the air flow channel of the suction pipe 10 is closed, and then the channel between the suction nozzle device and the garbage bin is closed. By setting the driving member 40 to drive the cover plate 30 to rotate relative to the mounting seat 20, the suction channel between the suction nozzle device and the garbage bin can be opened or closed, so that the cleaning and sweeping vehicle can adapt to different use environments and enrich the operation mode of the cleaning and sweeping vehicle.

[0035] For example, two suction pipe assemblies 100 may be connected to the suction nozzle device, and both suction pipe assemblies 100 are connected to a trash bin, and one of the suction pipe assemblies 100 may be opened or closed according to different use environments. For example, when the speed of the washing and sweeping vehicle is low and ordinary cleaning operations are performed, the cover plate 30 is driven by the driving member 40 and one of the suction pipes 10 is closed. That is to say, at this time, only one suction pipe assembly 100 is connected to the suction nozzle device and the trash bin, which can reduce the energy consumption of the washing and sweeping vehicle and reduce the noise during the working process. For another example, when the speed of the washing and sweeping vehicle is high and fast operations are performed, the cover plate 30 may be driven by the driving member 40 to open the suction pipes 10 of the two suction pipe assemblies 100, thereby realizing that both suction pipe assemblies 100 are connected to the trash bin, thereby improving the working efficiency of the washing and sweeping vehicle. Of course, the number of suction pipe assemblies 100 may also be three, four, six, etc., and one or more suction pipe assemblies may be opened or closed according to actual use requirements. The present application does not limit the number of suction pipe assemblies 100.

[0036] Exemplarily, the suction nozzle device may include a first suction chamber and a second suction chamber arranged front and back, and both the first suction chamber and the second suction chamber are connected to a suction tube assembly 100, and the passage between the suction chamber and the trash bin can be opened or closed by the suction tube assembly 100, that is, one of the suction chambers of the suction nozzle device can be operated, or two suction chambers can be operated at the same time according to the actual use environment.

[0037] According to the straw assembly 100 of the embodiment of the utility model, the driving member 40 can drive the cover plate 30 to open or close the air flow channel in the straw 10. The cover plate 30 is connected by setting a mounting seat 20, and the cover plate 30 is arranged in the cavity of the mounting seat 20. The mounting seat 20 can protect the cover plate 30 and can improve the stability of the cover plate 30 during rotation. The driving member 40 drives the cover plate 30 to open and close the straw 10, which is convenient for the washing and sweeping vehicle to adapt to different usage environments and enrich the operation mode of the washing and sweeping vehicle.

[0038] The straw assembly 100 includes a straw 10 and a mounting base 20, and the straw assembly 100 is configured to connect a trash bin and a nozzle device. For example, the mounting base 20 may be configured to connect the nozzle device, and the straw 10 is connected to the trash bin; or, the mounting base 20 is configured to connect the trash bin, and the straw 10 is configured to connect the nozzle device; or, the straw 10 may include a first pipe segment 11 and a second pipe segment 12, the first pipe segment 11 and the second pipe segment 12 are respectively connected to opposite ends of the mounting base 20, and the first pipe segment 11 is connected to the trash bin, and the second pipe segment 12 is connected to the nozzle device.
