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 (4), a lamp holder (3), a latching mechanism (1) provided within the lamp holder (3), and a lamp holder fixed cover (2) provided with a lock hole (21) therein. The latching mechanism (1) comprises a lock tongue (11) able to extend from or retract into the lamp holder (3) and a water nozzle blocker (12). When the lamp holder (3) is pressed on the liquid processor (4) and connected with the liquid processor (4) by the lamp holder fixed cover (2), the lock tongue (11) projects from the lamp holder (3) and enters into the lock hole (21) of the lamp holder fixed cover (2), so that the lamp holder fixed cover (2) is locked and cannot move. By means of the lamp holder fixed cover (2) being locked by the latching mechanism (1) and not able to be moved, the ultra-violet liquid processing device is reliably sealed by means of the substantial structure. The water nozzle blocker (12) enables the latching mechanism (1) to be unlocked only if the liquid source is disconnected, and the latching mechanism (1) can be in communication with the liquid source only if the 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. |
