pipe with a spray head main shell, and a
spray nozzle, wherein the lock shell is further provided with a
liquid injection hole and a liquid outlet hole; the
liquid storage bottleis fixed in the lock shell; the discharging port of the
liquid storage bottle is matched with the input end of the spray head cover; the pressing
piston of the spray head cover corresponds to the ejector head; the output end of the spray head cover communicates with the connecting
pipe; and the
spray nozzle is connected and mounted on the spray head main shell of the connecting
pipe and is matchedin the liquid outlet hole. According to the novel disinfection lock, a door lock and a
disinfectant are integrated together, when a door is opened, the
door handle can drive the
piston inside the
door handle to extrude when the door
handle rotates, and meanwhile, the
disinfectant is sprayed out to disinfect a hand, so that people disinfect the hand conveniently, and develop a
