Cleaning nozzle and cleaning trolley

Abstract

The invention discloses a cleaning nozzle. The cleaning nozzle comprises a nozzle body capable of moving along an object to be cleaned. The nozzle body is provided with an air inlet. A gas gathering area around the air inlet is formed on the lower side of the nozzle body. An opening where gas mingled with garbage passes through is arranged at the front end of the gas gathering area. Gas around the nozzle can enter into the gas gathering area all around and enters into the air inlet. A rib capable of guiding gas mingled with garbage to enter into the air inlet is arranged below the air inlet. The length direction of the rib is vertical to the front and back direction of the nozzle body, and the air inlet is divided into a front air inlet and a back air inlet. The invention further provides a cleaning trolley which uses the cleaning nozzle. As the rib arranged below the air inlet can guide gas mingled with garbage entered from the opening of the front gas gathering area into a nose air intake, the suction efficiency of the nozzle is high and the practicality is great.

Description

technical field [0001] The invention relates to the field of cleaning garbage by using vacuum negative pressure, in particular to a cleaning nozzle and a cleaning vehicle using the nozzle. Background technique [0002] In the field of using vacuum negative pressure to suck garbage, the cleaning nozzle plays an important role in garbage suction. Under the action of vacuum negative pressure, the gas mixed with garbage can enter the designated garbage storage area through the suction nozzle. For example, in the field of cleaning vehicles, especially in road sweeping vehicles, under the suction of the fan, garbage can enter the dustbin of the road sweeping vehicle through the suction nozzle together with the air, thereby achieving the purpose of road cleaning. Therefore, the design form of the suction nozzle also directly affects its own suction rate of garbage and the cleaning ability of the cleaning vehicle using the suction nozzle on the road surface. [0003] At present, in...

AI Technical Summary

Problems solved by technology

[0003] At present, in cleaning vehicles such as road sweepers equipped with cleaning nozzles, since the cleaning vehicles themselves have a fixed upper limit for the cleaning rate of road garbage, when the amount of road garbage and the thickness of the garbage layer exceed the existing cleaning capacity of the road sweeper , there will be garbage residue on the road after the cleaning operation, resulting in poor cleaning effect

The method of increasing the power of suction sources such as fans not only wastes energy, but also causes impacts on related components and affects their service life
