an air intake runner communicated with the first chamber, the air intake runner is configured to input an outside air into the first chamber to mix with the water flow to form a mixed water with bubbles; and
a water outlet cover, wherein a second chamber is formed between the water outlet cover and the mixer, and the at least one second water inlet hole and the at least one return hole are both communicated with the second chamber;
wherein the second chamber is configured to receive the mixed water flowing from the second water inlet hole, and the return hole is configured to flow the mixed water into the first chamber.

2. The device for generating water with air bubbles according to claim 1 , wherein the flow divider comprises a first disk portion and a cylinder portion, the first disk portion is configured to define a central axis, the flow divider comprises a first surface and a second surface that are opposite to each other, the cylinder portion is configured to extend from the first surface away from the second surface along the central axis.

3. The device for generating water with air bubbles according to claim 2 , wherein there are a plurality of first water inlet holes, the plurality of the first water inlet holes are formed in the first disk portion and are configured to extend through the first surface and the second surface, the plurality of the first water inlet holes are uniformly arranged along a circumferential direction of the first disk portion with the central axis as the center and the plurality of the first water inlet holes are located in an area surrounded by the cylinder portion, the air intake runner is formed in the first disk portion and is configured to extend through the first surface and the second surface and the air intake runner is located outside the area surrounded by the cylinder portion.

4. The device for generating water with air bubbles according to claim 1 , wherein the mixer comprises a second disk portion and an annular wall portion, the second disk portion is configured to define a central axis, and the second disk portion comprises a third surface and a fourth surface opposite to each other, the annular wall portion is configured to surround a peripheral edge of the second disk portion and protrude from the third surface and the fourth surface.

5. The device for generating water with air bubbles according to claim 4 , wherein the flow divider comprises a first disk portion and a cylinder portion, a portion of the annular wall portion protruding from the third surface of the second disk portion is configured to form an accommodating space, after the flow divider and the mixer are assembled, the first disk portion is accommodated in the accommodating space.

6. The device for generating water with air bubbles according to claim 4 , wherein the third surface of the second disk portion is configured to be provided with an annular slot, after the flow divider and the mixer are assembled, the annular slot is formed the first chamber.

7. The device for generating water with air bubbles according to claim 4 , wherein there are a plurality of second water inlet holes which are formed in the second disk portion and configured to extend through the third surface and the fourth surface, the plurality of second water inlet holes are uniformly arranged along a circumferential direction of the second disk portion with the central axis as the center; there are a plurality of return holes which are formed in the second disk portion and configured to extend through the third surface and the fourth surface, the plurality of return holes are uniformly arranged along the circumferential direction of the second disk portion with the central axis as the center.

8. The device for generating water with air bubbles according to claim 7 , wherein the plurality of return holes are closer to the central axis than the plurality of second water inlet holes.

9. The device for generating water with air bubbles according to claim 1 , further comprises:
