Spraying arm and cleaning device

Abstract

The invention provides a spraying arm and a cleaning device. The spraying arm and the cleaning device are used for cleaning a device body, wherein the spraying arm comprises a first body, a second body, a flow guide part and a nozzle, and the second body and the first body define a hollow cavity; the guide part is located on the outer wall of the first body, and one side surface of the flow guidepart is a flow guide surface; the nozzle is arranged on the outer wall of the first body, a flow channel is formed in the nozzle, and the flow channel communicates with the hollow cavity; and the flowchannel extends along the outer wall of the first body, a cleaning liquid is enabled to hit on the flow guide surface after flowing out along the outer wall of the first body. Due to the fact that the cleaning liquid becomes a jet area increasing the cleaning liquid when the bearing frame body is guided by a flow guiding surface, the cleaning range of the spraying arm is further enlarged accordingly, and the situation that a cleaning dead angle is caused due to incomplete coverage of the cleaning range of the spraying arm is avoided; and meanwhile, due to the fact that the cleaning range of the spraying arm is enlarged, the time for cleaning by the spraying arm is shortened, so that the technical effect of saving the cleaning fluid is achieved, and the use cost of a product is reduced.

Description

technical field [0001] The invention relates to a cleaning device, in particular to a spray arm and a cleaning device. Background technique [0002] At present, in the related technology, the nozzles on the spray arm are all in the shape of round holes, and the water flow ejected from the nozzles is a cylindrical jet. Since the coverage of the cylindrical jet is small, the cleaning area of ​​the spray arm is also limited. Uneven cleaning and poor cleaning effect; at the same time, due to the small cleaning area of ​​this spray arm, if you want to clean the tableware, you must increase the cleaning time, which causes a waste of cleaning liquid. Therefore, how to design a cleaning It is very necessary to have a spray arm with a large area and save cleaning fluid. Contents of the invention [0003] The present invention aims to solve at least one of the technical problems existing in the prior art or related art. [0004] To this end, a first aspect of the invention propose...
