AI Technical Summary
Existing fire extinguishing spray guns have foam nozzles that are difficult to replace when damaged, and there is also a problem of foam leakage.
A foam nozzle for a fire extinguishing spray gun was designed. By sliding and rotating the sliding plate, the spring force is used to achieve quick installation and disassembly of the nozzle and spray port. The connection between the embedded plate and the connecting plate is sealed with a rubber ring to ensure airtightness and prevent foam leakage.
It enables rapid replacement and maintenance of nozzles and spray nozzles, avoids foam waste, enhances the stability and reliability of the device, and reduces the corrosion of equipment caused by foam leakage.
