Description

Technical Field

[0001] The utility model relates to the field of decorative spraying, in particular to an anti-blocking spraying device. Background Technique

[0002] Wall decoration is one of the main links in decoration. At present, the most main method is to beautify and decorate the wall by scraping putty on the wall. The traditional putty scraping is realized by workers through manual scraping. With the progress of technology, a plunger pump is gradually used to spray the putty, which has high efficiency, saves labor and cost, and is more and more popular among decoration workers. The existing putty spraying device is generally used in cooperation with a mixing barrel. After use, it needs to be manually cleaned. Manual cleaning has low efficiency and cannot clean the connecting pipeline or the inner wall more efficiently and cleanly. It is easy to leave dry and solidified putty, which will block the inlet of the plunger pump or the inlet of the nozzle during the next use. At this time, it needs to be disassembled and cleaned, which is relatively troublesome. Content of the Utility Model
