Description

Technical Field

[0001] The utility model relates to the technical field of developing and flushing tanks, and more specifically to a flushing nozzle structure of a developing and flushing tank. Background Art

[0002] Liquid crystal display is an active matrix liquid crystal display driven by thin film transistors. It mainly uses electric current to stimulate liquid crystal molecules to produce points, lines, and surfaces to cooperate with the back light tubes to form the picture. The flushing nozzle of the LCD panel photolithography developing tank is an important equipment for cleaning the LCD panel photolithography developing tank.

[0003] After searching, the utility model patent with announcement number CN218360002U discloses a flushing nozzle for a liquid crystal panel photolithography developing tank, including a shell, an anti-blocking mechanism and a nozzle body. The anti-blocking mechanism includes a driving component, a filter barrel, a cleaning brush and a scraper. When the flushing nozzle needs to be used, the water inlet of the shell is connected to the water pipe, and the water flowing into the shell is filtered through the filter barrel to prevent impurities in the water from entering and causing clogging of the nozzle body. The driving component is started to drive the cleaning brush to rotate, and the cleaning brush rotates to clean impurities on the filter barrel to prevent impurities in the filter barrel from accumulating and clogging the filter barrel, resulting in water being unable to flow out. At the same time, the driving component drives the scraper to rotate. The rotation of the scraper can increase the flow rate of water and play a role of pressurization. The filter barrel is taken out regularly after use to pour out the impurities in the filter barrel to prevent the nozzle body from being blocked, thereby solving the problem that the existing developing tank flushing nozzle does not have an anti-blocking function.

[0004] However, the above patents still have the following shortcomings: when multiple nozzles are used in combination, it is not convenient to adjust the direction of the water flow sprayed by the nozzles, and it is only convenient to spray water in a specific direction for cleaning, which affects the cleaning quality; in addition, after the filter barrel filters the impurities in the water, the impurities in the filter barrel are easily moved by the impact of the water flow. Although they can be swept down, they are not collected, and the floating impurities will still affect the filtering effect. For this reason, we propose a flushing nozzle structure for a developer flushing tank. Utility Model Content
