Disclosed are a latching method ensuring a device can be sealed reliably and an ultra-violet liquid processing device. The ultra-violet liquid processing device comprises a liquid processor, a lamp holder, a latching mechanism provided within the lamp holder, and a lamp holder fixed cover provided with a lock hole therein. The latching mechanism comprise a locking dog able to extend from or retract into the lamp holder and a water nozzle blocker. When the lamp holder is pressed on the liquid processor and connected with the liquid processor by lamp holder fixed cover, the locking dog projects from the lamp holder and enter into the lock hole of the lamp holder fixed cover, so that the lamp holder fixed cover is locked and cannot move. By means of the lamp holder fixed cover being locked by the latching mechanism and not able to be moved, the ultra-violet liquid processing device is sealed reliably by means of the substantial structure. The water nozzle stopper enables the latching mechanism to be unlocked only if the liquid source is disconnected, and the latching mechanism can be in communication with the liquid source only if the latching mechanism is in a locked state, so that the liquid to be processed can efficiently be prevented from leaking and the processing of the liquid is ensured. |
