Abstract: A filter holder has an assembling base, a trigger component, and a body. The assembling base includes a mounting portion and a body holder having a connecting bole, a slit, a blocking end, and an engaging groove. The trigger component is connected to the body holder. The body is rotatably connected to the assembling base and has a cap, a connecting tube inserted into the connecting hole of the body holder, and a locking rib able to be located in the slit and the engaging groove. The trigger component is pressed away from the slit to drive the body holder to release an engagement between the engaging groove of the body holder and the locking rib of the body.

Abstract: A water-filtration device filtrates water, has a main-filtration path and a bypassing-filtration path, and comprises a filter head, a water filter, a guiding assembly and an adjusting valve movably mounted at the filter head. The guiding assembly is mounted at the filter head and connected to the water filter. An O-ring of the adjusting valve can block an end of a bypassing portion of the guiding assembly. In the main-filtration path, water entering from a water inlet of the filter head does not pass through the bypassing portion, thereby completely passing through filter materials in a first filtrating room and a second filtrating room of the water filter. Water in the bypassing-filtration path passes through the bypassing portion and the filter material in the first filtrating room. The O-ring does not reach into the bypassing portion, thereby reducing wear and damage to the O-ring, and avoiding water leakage.
