Abstract

A water outlet terminal with the function of purified water outlet, includes a body and a mandrel. A raw water outlet hole and a pure water outlet hole are arranged on the end surface of the mandrel. The mandrel has a raw water inlet cavity and a purified water inlet cavity which are independent from each other. One end of the raw water inlet cavity and the purified water inlet cavity are communicated with the raw water outlet hole and the purified water outlet hole, and the other ends are the raw water inlet hole and the purified water inlet hole. The water outlet terminal has a purified water opening member with a first position and a second position corresponding to an open or closed state of purified water inlet hole, a cover assembly, with a purified water outlet passage in the geometric center of the assembly.

a first end of the raw water inlet cavity and a first end of the purified water inlet cavity are respectively in communication with the raw water outlet hole and the purified water outlet hole,
a second end of the raw water inlet cavity and a second end of the purified water inlet cavity respectively define a raw water inlet hole and a purified water inlet hole,
the purified water opening member is configured to be switched between a first position and a second position to enable the purified water inlet hole to be in an open state or a closed state,
a water outlet passage at a geometric center of the cover assembly is in fluid communication with the purified water inlet cavity,
the mandrel defines a first opening at a first side of the raw water inlet cavity and a second opening at a first side of the purified water inlet cavity respectively extending along a direction of flowing water,
at least one of:
the first opening at the first side of the raw water inlet cavity extends a length of the raw water inlet cavity in the direction of flowing water, or
the second opening at the first side of the purified water inlet cavity extends a length of the purified water inlet cavity in the direction of flowing water,

the first opening and the second opening are configured to be covered by a tab, and
the first side of the raw water inlet cavity and the first side of the purified water inlet cavity are on a same side of the mandrel.

2. The water outlet terminal with the purified water outlet according to claim 1 , wherein:
a remainder of the raw water inlet cavity and a remainder of the purified water inlet cavity are sealed portions, and
peripheries of the first opening and the second opening are welded to the tab to seal the first opening and the second opening.

3. The water outlet terminal with the purified water outlet according to claim 2 , wherein:
a second side of the purified water inlet cavity away from the raw water inlet cavity comprises an open end, and
the open end is sealed to a second tab by welding.

4. The water outlet terminal with the purified water outlet according to claim 2 , wherein the raw water inlet hole is always in an open state.

5. The water outlet terminal with the purified water outlet according to claim 4 , wherein the raw water outlet hole comprises at least two water outlet holes with different outlet forms.

6. The water outlet terminal with the purified water outlet according to claim 5 , wherein:
the at least two water outlet holes comprise a first water outlet hole and a second water outlet hole,
the second water outlet hole is disposed on a periphery of the first water outlet hole, and
the first water outlet hole and the second water outlet hole are concentric.

7. The water outlet terminal with the purified water outlet according to claim 6 , wherein the purified water outlet hole is disposed at a center of the first water outlet hole.

8. The water outlet terminal with the purified water outlet according to claim 7 , wherein:
the first water outlet hole is a bubble water outlet, and
an aerator is disposed on the bubble water outlet.

9. The water outlet terminal with the purified water outlet according to claim 7 , comprising:
a raw water switching member for switching between the first water outlet hole and the second water outlet hole, wherein:
when the raw water switching member is operated, one of the first water outlet hole or the second water outlet hole is in an open state and the other of the first water outlet hole or the second water outlet hole is in a closed state.

10. The water outlet terminal with the purified water outlet according to claim 9 , wherein:
