Problems solved by technology
After a period of use, a large amount of dust is usually accumulated on the filter screen cover, which leads to a decrease in the suction of the vacuum cleaner and reduces the filtering effect of the filter screen cover.
The minimum requirement is to stop the vacuum cleaner and disassemble the body for cleaning. The steps are cumbersome and inconvenient to use.
[0003] With the development of the national economy and the continuous renewal and development of urban and rural roads, a large number of road cleaning tools are needed. It is difficult to achieve the purpose of cleaning only by manual cleaning, and the labor cost is high. Road sweepers have gradually become the mainstream of road cleaning tools.

The invention provides a system for blowing back and dredging the dust suction pipeline of a sweeping vehicle, which includes a fluid generating part, a fluid pipeline switching part, a fluid conveying pipeline and a fluid backflushing part; the fluid generating part is connected to the fluid pipeline switching part, through the fluid pipeline switching part, the fluid delivery pipeline is switched and connected, and the other end of the fluid delivery pipeline is connected to the fluid blowback part; the fluid blowback part is arranged on the dust suction pipe of the sweeper The fluid backflushing part cleans and dredges the pipeline by fluid backflushing.
Description
technical field [0001] The invention relates to the field of road surface cleaning, in particular to a back-blowing and dredging system for dust suction pipes of sweeping vehicles. Background technique [0002] A vacuum cleaner is a commonly used cleaning device that can generate very strong suction to suck dust or foreign matter accumulated on floors, carpets, walls, or other surfaces into its garbage collection device. A vacuum cleaner usually includes a body, a connecting hose and a suction nozzle, wherein a vacuum motor is provided in the body, and the lower part of the body is a dust collection cup, and the vacuum cleaner motor and the dust collection cup are separated by an air filter. When working, the motor of the vacuum cleaner generates negative pressure inside the dust collection cup to generate suction, so that the air containing dust or foreign matter is sucked in through the suction nozzle and the connecting hose, and passes through the air filter device, such ...
