Sealed liquid injection cavity cleaning device and using method thereof

Abstract

The invention discloses a sealing type liquid injection cavity cleaning device and a using method thereof. The sealing type liquid injection cavity cleaning device comprises an outer layer pipe wall arranged on a liquid injection sleeve cup; the liquid injection needle is arranged on the inner side of the outer-layer pipe wall in a sliding mode so as to adjust liquid injection or cleaning, and a liquid injection channel is formed in the inner side of the liquid injection needle in a penetrating mode; the first cleaning hole is formed in the side wall of the liquid injection needle and is communicated with the interior of the liquid injection channel; the second cleaning holes are formed in the side wall of the outer-layer pipe wall, and the second cleaning holes and the first cleaning holes are staggered; by arranging the outer-layer pipe wall, the liquid injection needle, the rubber plug, the notch and the second cleaning hole, the liquid injection needle and the inner side of the cup sleeve can be cleaned conveniently, inconvenience caused by disassembling and installing the device to clean the liquid injection cavity is avoided, time is saved, and the situation that the liquid injection cavity is cleaned due to the fact that the device does not need to be disassembled can be avoided in the installation process. The problem of alignment accuracy error of the liquid injection needle and the sleeve cup opening is solved, and the use effect is improved.
