The first lamp board 214, the second lamp board 314, and the third lamp board 45 are all connected to the control board 72.

[0052] The working principle in this embodiment is as follows: Since the rotating body 11 can rotate up and down relative to the main valve shaft 12, one of the first gravity water filter assembly 2 and the second gravity water filter assembly 3 is located above the main valve shaft 12, and the other is located below the main valve shaft 12. For example, when the first gravity water filter assembly 2 is located above the main valve shaft 12 and the second gravity water filter assembly 3 is located below the main valve shaft 12, during use, the water in the upper first glass body 21 will flow into the lower second glass body 31 due to gravity, creating a negative pressure in the first glass body 21. Smoke can enter the first glass body 21 through the air inlet 120, air inlet channel 131, second air inlet hole 210, and first air inlet hole 29. At this time, when the water flows into the second glass body 31, it will squeeze the smoke in the second glass body 31 from the third air outlet hole 312 and the fourth air outlet hole 313 into the air outlet channel 132, and then flow through the air guide channel 510, the fifth air outlet hole 59, and the air outlet 511 into the first alloy tube 55 or the second alloy tube 56, and then flow out from the first alloy tube 55 or the second alloy tube 56, the soft rubber tube 61, the metal tube 63, and the glass tube 64, making it convenient for users to suck up. Furthermore, since the air intake channel 131 is above the air outlet channel 132, the air intake holes of the first gravity water filter assembly 2 and the second gravity water filter assembly 3 will only be connected to the air intake channel 131 when they are located above the main valve shaft 12. The air outlet holes are separated from the air outlet channel 132 by the main valve shaft 12, so only air can enter and not exit. Similarly, the first gravity water filter assembly 2 and the second gravity water filter assembly 3 can only exit and not enter air when they are located below the main valve shaft 12, thereby preventing air leakage between the first glass body 21 and the second glass body 31.

[0053] The above structure allows the smoke to be filtered by gravity water, resulting in better filtration and hygiene. At the same time, the smoke can automatically flow to the suction nozzle assembly 6 under the pressure of gravity water, making smoke extraction more convenient and effortless, thus improving the user experience.
