Jet regulator for switching water spray patterns

A jet regulator for switching water spray patterns, comprising:

• a body;
• a divider coaxially disposed at a first end of the body;
• and
• a water outlet cover coaxially disposed at a second end of the body, wherein:
• a first side of the divider facing a water inflow end is disposed with a convex portion at a center of a circle,
• a plurality of water dividing hole sets are circumferentially disposed between an outer circumference of the convex portion and an inner circumference of the divider at intervals,
• each of the plurality of water dividing hole sets comprises a plurality of water dividing holes in a radial direction,
• the outer circumference of the convex portion is an annular guiding inclined surface,
• water reaches the convex portion and is guided to flow to the plurality of water dividing hole sets by the guiding inclined surface,
• the water outlet cover is provided with a plurality of first water outlet holes and a plurality of second water outlet holes,
• the plurality of first water outlet holes are uniformly disposed on an outer circumference of the plurality of second water outlet holes,
• an axial center of the body is provided with a connecting member connected to the divider,
• an outer wall of the connecting member and an inner wall of the body are radially connected by a plurality of ribs,
• the plurality of ribs, the outer wall of the connecting member, and the inner wall of the body jointly define a plurality of chambers which are circumferentially disposed,
• one of two adjacent chambers of the plurality of chambers is a first water outlet chamber,
• the other one of the two adjacent chambers is a second water outlet chamber,
• a water outlet of the first water outlet chamber is disposed at a bottom of the first water outlet chamber which is close to the inner wall of the body,
• the bottom of the first water outlet chamber corresponding to the plurality of water dividing hole sets is provided with a first guiding surface,
• the first guiding surface inclines downwardly in a direction from the outer wall of the connecting member to the inner wall of the body,
• a lower end of the first guiding surface is connected to the water outlet of the first water outlet chamber,
• the water flows out from the plurality of water dividing hole sets, and then flows into the water outlet of the first water outlet chamber through the first guiding surface,
• the water outlet of the first water outlet chamber is disposed with a grid rectifier,
• a water outlet of the second water outlet chamber is disposed at a side wall of the second water outlet chamber corresponding to the outer wall of the connecting member,
• a bottom portion of the second water outlet chamber is disposed with a second guiding surface,
• the second guiding surface inclines downwardly in a direction from the inner wall of the body to the outer wall of the connecting member,
• a lower end of the second guiding surface is connected to the water outlet of the second water outlet chamber,
• the water flows out from the plurality of water dividing hole sets, and then flows into the water outlet of the second water outlet chamber through the second guiding surface,
• an enlarged port is disposed at a position of the body below the water outlet of the second water outlet chamber,
• the enlarged port has a gradually enlarged opening from one end adjacent to the second water outlet chamber to the other end,
• when the divider is connected to the connecting member, a gap is formed between a water outflow end of the plurality of water dividing hole sets and an upper surface of the plurality of ribs, and the first water outlet chamber and the second water outlet chamber are communicated by the gap,
• when the body is subjected to a rotational force along a circumferential direction, the body and the divider are relatively rotated so that all of the plurality of water dividing hole sets are located above the first water outlet chamber or the second water outlet chamber,
• when the plurality of water dividing hole sets are located above the first water outlet chamber, the water flows through the plurality of water dividing holes, flows through the first water outlet chamber, and then flows out from the first plurality of water outlet holes,
• when the plurality of water dividing hole sets are located above the second water outlet chamber, the water flows through the plurality of water dividing hole sets, flows through the second water outlet chamber, and then flows out from the plurality of second water outlet holes, and
• external air from the plurality of first water outlet holes enters into the first water outlet chamber through the water outlet of the first water outlet chamber, then enters into the water in the second water outlet chamber through the gap, and then flows out from the water outlet of the second water outlet chamber with the water in the second water outlet chamber, the water and the external air is mixed by a water-air mixing member to form the aerated water, and then the aerated water flows out from the plurality of second water outlet holes.
