The present disclosure relates to sanitary wares, and in particular relates to a water outlet device and a kitchen faucet.
Existing water outlet devices in the sanitary field, such as described in CN103223382B, which describes a sprinkler assembly for a faucet, comprises: a main body configured to receive a fluid supply and an end surface in fluid connection with the main body. The end surface has a plurality of nozzles in a non-linear arrangement for guiding fluid from the sprinkler. The plurality of nozzles are configured to guide fluid flow to form a wedge-shaped spray between the end surface and a focus area, which is located at a focal length of the sprinkler. The spray forms a linear spray arrangement in the focal area, and the spray comprises a plurality of fluid streams. Each of the plurality of fluid streams corresponds to one of the plurality of nozzles, and each of the plurality of fluid streams is configured to be between the end surface and the focus area and is configured to avoid intersecting any other fluid stream of the plurality of fluid streams. The plurality of nozzles of the sprinkler assembly can only provide a single spray pattern, and each of the plurality of fluid streams is configured to be between the end surface and the focus area and is configured to avoid intersecting with any other fluid stream of the plurality of fluid streams, causing the fluid spray to be easily splashed.
Another water outlet device is disclosed in CN205731687U, which provides a shower with adjustable impact force and angle of splash. The shower comprises a housing, a water dividing plate, a middle plate, a water barrier, an inner water outlet panel, and an outer water outlet panel. The housing has a cavity with one end open, and the water dividing plate, the middle plate, the water barrier, and the inner water outlet panel are all disposed in the cavity of the housing. The outer water outlet panel is fastened on the open end of the housing. The water dividing plate is placed in the cavity of the housing, and the middle plate, the water barrier, and the outer water outlet panel are fixedly sleeved together. The inner water outlet panel is arranged between the water barrier and the outer water outlet panel, and multiple outlet holes of the inner water outlet panel are disposed opposite to multiple outlet holes of the outer water outlet panel. A top of the middle plate is provided with a rotating shaft, which is rotatably sleeved in a middle hole of the water dividing plate. A water passage of the housing passes through a water passage of the water dividing plate and the middle plate and is divided into two passages. One of the two passages is connected to the multiple outlet holes of the outer water outlet panel, and the other of the two passages is connected to the multiple outlet holes of the outer water outlet panel after passing through the multiple outlet holes of the inner water outlet panel. An outlet nozzle of the inner water outlet panel is inserted into an outlet nozzle of the outer water outlet panel, causing the outer water outlet panel to eject water along an annular gap of the outlet nozzles of the inner water outlet panel and the outer water outlet panel when the outer water outlet panel emits water, and the water spray is poor in practicality.

Increasing the distance between the first water outlet portion and the second water outlet portion can improve the uniformity of water discharge of the first water outlet nozzle of the first water outlet portion.
A plurality of water outlet nozzles are evenly arranged at intervals in the circumferential direction, which is especially convenient for arrangement within the first water outlet portion and the second water outlet portion having annular structures, with compact structure and reasonable layout.
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, which is convenient for assembly and compact in structure.
The fluid ejected from at least two of the plurality of second water outlet nozzles collide in the focus area or between the water outlet device and the focus area. The collision forms a particle-shaped water curtain to prevent water splashing and improve fluid impact. This effect is particularly prominent on the kitchen faucet, which is convenient for washing and cleaning.
The collision points of the two second water outlet nozzle groups define an arc-shaped lattice structure with beautiful appearance and large cleaning area.
The fluid ejected from the two second water outlet nozzle groups collide in the focus area, which has a beautiful appearance and prevents water splashing.
The present disclosure will be further described below in combination with the accompanying drawings and embodiments.

A valve body 145 is secured on the second water dividing cavity 141. The second switching mechanism 32 is disposed on the second water dividing body 14. The second switching mechanism 32 comprises a valve core 321 slidably connected to the valve body 145, a second spring 322, and a boat-shaped switch 323. The valve core 321 is secured with a seal ring 3211, and the second spring 322 abuts and is disposed between the valve core 321 and the valve body 145. The boat-shaped switch 323 is swingably connected to the second water dividing body 14 and extends out of a give-way hole 122 penetrating the inner side and the outer side of the body 12. An inner side of the boat-shaped switch 323 is disposed with a dial fork 3231, and the valve core 321 comprises a protruding end 3213 extending out of the valve body 145. The protruding end 3213 is annularly recessed to define an annular groove 3212. The dial fork 3231 is disposed in the annular groove 3212.
