Abstract

The present disclosure discloses a water outlet device and a kitchen faucet. The water outlet device comprises three water outlet passages, a first water outlet portion comprising one or more first water outlet nozzles, a second water outlet portion comprising one or more second water outlet nozzles, and a third water outlet portion. Each of the first water outlet portion and the second water outlet portion respectively has an annular structure. The second water outlet portion is separated from the first water outlet portion in an upper and lower direction. The one or more second water outlet nozzles correspond to the one or more first water outlet nozzles to enable fluid ejected from the one or more second water outlet nozzles to pass through the one or more first water outlet nozzles.

First claim

What is claimed is:

1 . A water outlet device, comprising:
three water outlet passages, a first water outlet portion comprising one or more first water outlet nozzles, a second water outlet portion comprising one or more second water outlet nozzles, and a third water outlet portion, wherein:
each of the first water outlet portion and the second water outlet portion respectively has an annular structure,
the second water outlet portion is separated from the first water outlet portion in an upper and lower direction,
the one or more second water outlet nozzles correspond to the one or more first water outlet nozzles to enable fluid ejected from the one or more second water outlet nozzles to pass through the one or more first water outlet nozzles,
the third water outlet portion is disposed in the annular structures of the first water outlet portion and the second water outlet portion, and
the three water outlet passages are respectively in communication with the one or more first water outlet nozzles, the one or more second water outlet nozzles, and the third water outlet portion.

2 . The water outlet device according to claim 1 , wherein ends of the one or more second water outlet nozzles are separated from an inner end surface defined by inner ports of the one or more first water outlet nozzles in the upper and lower direction by a gap.

3 . The water outlet device according to claim 1 , wherein:
the second water outlet portion is separated from the first water outlet portion in the upper and lower direction to define an area, and the area defines a portion of a first water outlet passage of the three water outlet passages in communication with the one or more first water outlet nozzles.

4 . The water outlet device according to claim 1 , wherein:
the one or more first water outlet nozzles comprises a plurality of first water outlet nozzles, the plurality of first water outlet nozzles are evenly and circumferentially disposed at intervals, the one or more second water outlet nozzles comprises a plurality of second water outlet nozzles, and the plurality of second water outlet nozzles are evenly and circumferentially disposed at intervals.

5 . The water outlet device according to claim 4 , wherein:
the annular structures of the first water outlet portion and the second water outlet portion are circular annular structures, the plurality of first water outlet nozzles and the plurality of second water outlet nozzles are both annularly arrayed relative to axis of the circular annular structures, and the plurality of second water outlet nozzles are aligned with the plurality of first water outlet nozzles in the upper and lower direction.

6 . The water outlet device according to claim 1 , wherein:
the first water outlet portion comprises a first water outlet cover defining a first annular structure, an inner periphery and an outer periphery of the first water outlet cover respectively extend upward to define a first inner peripheral wall and a first outer peripheral wall, the first water outlet cover comprises the one or more first water outlet nozzles, the second water outlet portion comprises a second water outlet cover defining a second annular structure, an inner periphery and an outer periphery of the second water outlet cover respectively extend upward to define a second inner peripheral wall and a second outer peripheral wall, the second water outlet cover comprises the one or more second water outlet nozzles, the second water outlet portion is disposed between the first inner peripheral wall and the first outer peripheral wall, and the second water outlet cover is separated from the first water outlet cover in the upper and lower direction.

7 . The water outlet device according to claim 1 , wherein in a projection along an ejecting direction of the one or more second water outlet nozzles, inner walls of the one or more first water outlet nozzles encompass water outlet ports of the one or more second water outlet nozzles.

8 . The water outlet device of claim 1 , wherein:
the one or more first water outlet nozzles comprise a plurality of first water outlet nozzles, the one or more second water outlet nozzles comprise a plurality of second water outlet nozzles, and fluid ejected from at least two second water outlet nozzles of the plurality of second water outlet nozzles collides in a focus area or collides between the water outlet device and the focus area.

9 . The water outlet device of claim 8 , wherein:
at least some second water outlet nozzles of the plurality of second water outlet nozzles are divided into two second water outlet nozzle groups, fluid ejected from the two second water outlet nozzle groups collides in the focus area or collides between the water outlet device and the focus area, and collision points of the two second water outlet nozzle groups define an arc-shaped lattice structure.

10 . The water outlet device according to claim 8 , wherein:
the plurality of second water outlet nozzles are all divided into two second water outlet nozzle groups, and fluid ejected from the two second water outlet nozzle groups collides in the focus area.

11 . The water outlet device according to claim 8 , wherein:
at least some second water outlet nozzles of the plurality of second water outlet nozzles are divided into two second water outlet nozzle groups, fluid ejected from the two second water outlet nozzle groups intersects in different planes, an intersecting position of the different planes defines the focus area, and fluid ejected from remaining second water outlet nozzles of the plurality of second water outlet nozzles not divided into the two second water outlet nozzle groups collides between the water outlet device and the focus area.

12 . The water outlet device of claim 11 , wherein a cross section of the fluid ejected from the two second water outlet nozzle groups defines an arc-shaped lattice structure at the focus area.

13 . The water outlet device according to claim 11 , wherein:
a cross section of the fluid ejected from the two second water outlet nozzle groups defines a first arc-shaped lattice structure at the focus area, and collision points of the remaining second water outlet nozzles define a second arc-shaped lattice structure.

14 . The water outlet device according to claim 11 , wherein:
a cross section of the fluid ejected from the two second water outlet nozzle groups defines in an arc-shaped lattice structure at the focus area, and the arc-shaped lattice structure surrounds collision points of the remaining second water outlet nozzles.

15 . The water outlet device of claim 1 , wherein:
the one or more first water outlet nozzles comprise a plurality of first water outlet nozzles, the one or more second water outlet nozzles comprise a plurality of second water outlet nozzles, at least some second water outlet nozzles of the plurality of second water outlet nozzles are divided into two second water outlet nozzle groups, fluid ejected from the two second water outlet nozzle groups intersect in different planes, an intersecting position of the different planes defines a focus area, and a cross section of the fluid ejected from the two second water outlet nozzle groups defines an arc-shaped lattice structure in the focus area.

16 . A water outlet device, comprising:
