As shown in fig. 8 and 9, fig. 8 is a side view of another exemplary embodiment of the bubble water generating apparatus of the present invention, and fig. 9 is a sectional view of another exemplary embodiment of the bubble water generating apparatus of the present invention. In this embodiment, it is different from the embodiment of the shower head described above in that:

the bubbler includes a filter assembly 100, a flow splitter 30, a mixer 50, a screen assembly 70, and a surface cover 90. The cover 90 is fastened to the mixer 50 and the splitter 30, and forms a second chamber 80 with the mixer 50, and the filter screen assembly 70 is disposed in the second chamber 80. An inlet flow channel 314 is formed between the side wall of the outlet cover 90 and the side wall of the diverter 30, and the inlet flow channel 314 communicates with the first chamber 60.

When water flows through the filter element 100, the first water inlet 313 and the second water inlet 513 in sequence, since the flow area of the second water inlet 513 is larger than the flow area of the first water inlet 313, a certain negative pressure is generated in the second water inlet 513 according to the bernoulli principle, so that external air is sucked into the bubbler from the air inlet flow channel 314. The principle of generating micro-bubbles in the bubbler is substantially the same as that of the above-described embodiment of the showerhead, and thus, the detailed description thereof is omitted.

Of course, in other embodiments, the inlet flow conduit may also be formed on the flow splitter or other suitable component/location.

To sum up, the utility model discloses an bubble water produces device's advantage and beneficial effect lie in:

the water flow sequentially flows through the first water inlet hole 313 and the second water inlet hole 513, because the flow area of the second water inlet hole 513 is larger than that of the first water inlet hole 313, according to the bernoulli principle, a certain negative pressure is generated in the second water inlet hole 513, so that the outside air sequentially passes through the air inlet flow channel 314 and the first chamber 60 and is sucked into the second water inlet hole 513, and forms a mixed water flow with certain bubbles with the water flow, after the mixed water flow enters the second chamber 80, a part of the mixed water flow returns to the first chamber 60 through the backflow hole 514, and then is sucked into the second water inlet hole 513, and the circulation is repeated. Since a part of the returned mixed water flow fills the first chamber 60 during the reciprocating circulation to prevent the external air from being sucked into the bubble water generating device, the air intake amount is reduced, and as the part of the mixed water flow is sucked into the second water inlet 513 again, the external air is continuously sucked when the first chamber 60 is not filled with the mixed water flow, thereby achieving the effect of automatically controlling the air intake amount of the external air. Meanwhile, the air inflow of the outside air is effectively controlled, so that bubbles in the mixed water flow with certain bubbles are smaller, and the bubble water generating device can generate bubble water with micro bubbles.
