When the nozzle is blocked, the water pressure in the drain pipe exceeds the spring's tension on the sealing ball, causing the sealing ball to separate from the second ring. Water then drains from the drain pipe. Through the coordination of the drain pipe, the first ring, the spring, the sealing ball, and the second ring, users can visually determine whether the nozzle is blocked by observing whether water is draining from the drain pipe, thus facilitating nozzle clogging assessment.
