In this embodiment, the bottom wall of the water diversion area 223 is higher than the bottom wall of the water channel 222, and the bottom wall of the second opening 227 is higher than the bottom wall of the first opening 226, so that the liquid gradually rises and gradually advances layer by layer in the water channel 222 and the water diversion area 223, the trend that the water flow flows out of the water diversion element 22 from the adjacent channels in advance is relieved, the water flow is facilitated to be fully diffused in the water channel 222 and the water diversion area 223, so that the opposite sides of the water inlet 221 have enough water drainage, and the liquid 233 in the water diversion area can almost enter the water outlet 224 through the second opening 227 at the same time, so as to ensure the uniformity of the water drainage; the water channel 222, the water diversion area 223 and the water outlet tank 224 are communicated through the side wall openings, so that the flow of water flow can be controlled, the water flow can be guided to flow, the uniform dispersion of liquid is realized, and the wetting effect of the filter element 21 is improved.

Meanwhile, each water storage tank 2231 is communicated with a first opening 226 and two second openings 227, the first openings 226 and the second openings 227 are staggered, and the distances from the first openings 226 to the second openings 227 corresponding to the same water storage tank 2231 are equal; the water flow passing through the first openings 226 can flow to the corresponding second openings 227 at the same time, and the liquid levels at the two second openings 227 are approximately equal, so that the synchronization and uniformity of the water output of a single water storage tank 2231 are improved, the water at the water drain port 225 can be uniformly fed, the water drain port 225 can be conveniently used for synchronously draining, and the purpose of uniformly wetting the filter element 21 is realized; it will be appreciated that a single reservoir 2231 may also be in communication with a plurality of first openings 226 or with one or more second openings 227, depending on the operating conditions.

In the present embodiment, the bottom wall of the second opening 227 corresponding to the same water storage tank 2231 is equal in height, so that the second opening 227 of the same water storage tank 2231 can discharge water synchronously; the heights of the bottom walls of the second openings 227 corresponding to the different water storage tanks 2231 gradually decrease along the direction away from the water inlet 221, so that the water outlet synchronism of the whole water diversion area 223 can be improved; meanwhile, the water diversion member 22 is symmetrical along a straight line passing through the center of the water feeding port 221 in the radial direction, so that the two sides of the symmetrical axis form the same structure and layout, the structural complexity of the water diversion member 22 can be reduced, and convenience is provided for the design and production processing of the water diversion member 22.

Finally, in the four water storage tanks 2231 of the present embodiment, the second openings corresponding to the two water storage tanks 2231 near the water inlet 221 are the second openings a 2271, and the second openings b2272 corresponding to the two water storage tanks 2231 far away from the water inlet 221, where the bottom wall of the second opening a 2271 is higher than the bottom wall of the second opening b2272, and the lower bottom wall enables the water storage tanks 2231 far away from the water inlet 221 to synchronously discharge water with other water storage tanks 2231 under the condition that the internal liquid level is relatively lower, so as to realize synchronous water discharge of the whole water distribution area 223, and promote the uniformity of the water discharged by the water distribution member 22, thereby realizing better wetting effect of the filter element 21.

The liquid in the water diversion area 223 is uniformly dispersed to the water outlet tank 224 in a plurality of directions through the second openings 227, so that the problem that the water flow of the water outlet tank 225 on one side is too large or too small due to the distance difference between the water inlet tank 221 and different water outlet tanks 225 in the prior art is avoided, and the water outlet synchronism and uniformity of the water outlet tanks 225 in all directions are improved; meanwhile, the water drain ports 225 are uniformly distributed above the filter element 21 at intervals along the circumferential direction of the filter element 21, so that the water quantity of each part of the filter element 21 is further ensured, and the uniform wetting of the whole filter element 21 is facilitated. When the water drain hole 225 is too slow or is blocked, so that the liquid accumulated in the water outlet tank 224 overflows the water outlet tank 224, the redundant liquid can flow into a drain tank 228 surrounding the outer side of the water outlet tank 224 and flows to the filter element 21 through the drain outlet, so that the water outlet pressure of the water outlet tank 224 is relieved, the water absorption capacity of the filter element 21 is improved, and the humidifying effect of the humidifier 1 is improved.
