Spray nozzle of window scraping device

Abstract

The invention relates to a device for cleaning the surface of glass, in particular to a spray nozzle of a window scraping device. The spray nozzle comprises a spray nozzle shell. The spray nozzle shell is provided with a steam inlet pipe allowing steam to be injected, a steam chamber and two or more steam spray holes. The steam inlet pipe and the steam spray holes are all communicated with the steam chamber. Steam entering the steam chamber through the steam inlet pipe is sprayed out through the steam spray holes. Steam is simultaneously sprayed out through the steam spray holes, and therefore the spray area of the steam is enlarged, the steam spray range of the surface of the glass can be widened through the spray nozzle, steam can be uniformly sprayed to the surface of the glass, the cleaning effect is better, cleaning is comprehensive, and a cleaner effect is achieved; the arrangement direction of the steam spray holes is parallel to the length direction of a scraping strip, and therefore in the cleaning process, due to the fact that the arrangement direction of all the steam spray holes is parallel to the length direction of the scraping strip, the steam spray holes are used in cooperation with the long-strip-shaped flexible scraping strip for spraying steam to most of the area swept by the long-strip-shaped flexible scraping strip, the cleaning effect is better, cleaning is comprehensive, and the better cleaning effect is achieved.

Description

Technical field [0001] The invention relates to a glass surface cleaning device, in particular to a nozzle for window scraping which can spray steam. Background technique [0002] The window squeegee is mainly used for cleaning the glass surface (or other hard surface). It can suck and remove the liquid (such as cleaning liquid) on the glass surface (or other hard surface) and / or spray the cleaning liquid on the glass surface. For example, the Chinese Patent Application Publications CN103222831A, CN103251348A, CN101909499A, and CN103251347A all disclose a glass surface cleaning device, that is, a technical solution for a window scraper. The surface cleaning device disclosed in CN103251347A can be sprayed or sprayed with spray or water. A water spray device, the spray or water spray device includes a nozzle, when cleaning, the nozzle is used to spray or spray water to achieve a better cleaning effect. However, the nozzle is provided with only one spray hole, which can only spray ...

AI Technical Summary

Problems solved by technology

However, the nozzle has only one spray hole, which can only spray or spray water on a very small local area of ​​the glass surface (or other hard surfaces) and presents an uneven state. The design is unreasonable and the cleaning effect is not good.

[0003] In addition, the general window scraper is equipped with a long flexible scraper. When the nozzle has only one spray hole, it obviously cannot cooperate with the cleaning work of the long flexible scraper. The area swept by the long flexible scraper has only a partial Being sprayed, most of the whole area is not sprayed, and the cleaning effect is not good
