Description

Technical Field

[0001] The utility model belongs to the technical field of window cleaning device structures, in particular to a window cleaning device. Background Art

[0002] For high-rise residents, cleaning window glass has always been a problem, especially outdoor glass, which is particularly troublesome. In order to solve this problem, window cleaners with handle bars have appeared on the market. The window cleaner is set on a long handle bar, and the user can hold the handle bar to clean the outside of the glass. In order to facilitate the user to hold the handle bar and wipe the outside of the glass without leaning out, a U-shaped bar is set on the side of the handle. The user holds the handle bar with one hand and the U-shaped bar with the other hand, or both hands hold the U-shaped bar; therefore, U-shaped bar window cleaners have become the mainstream products on the market.

[0003] In order to make cleaning the glass more convenient, the window cleaner has a wiping head on one side and a wiper on the other side. After the wiping head is used to wipe, the wiper is used to wipe dry. However, there is a problem after the window cleaner is installed with a U-shaped rod. The handle with the U-shaped rod has a specific direction. After using the wiping head to wipe the outer glass, when the wiping head is turned to use the wiper to scrape the glass, the U-shaped rod is facing outward and away from the human body, which is very awkward to use. Therefore, products on the market gradually abandon the use of the U-shaped rod, such as Chinese patent CN2012204332892, which has always been a multi-purpose window cleaner. Summary of the invention

[0004] The utility model aims to provide a window cleaning device with a stable structure and capable of rotation.
