Therefore, water in the water tank 1 is sent into the upper shower chamber 4 through the water pump 5, the water flows to the evaporation filter element 3 from the lower water hole 412 of the upper shower chamber 4, the water flows from top to bottom in the evaporation filter element 3 to keep the whole evaporation filter element 3 moist, the redundant water continuously flows downwards to the water receiving tray 2 and then flows back to the water tank 1 from the water tank opening 12, so that water circulation is formed between the water tank 1 and the evaporation filter element 3, the lower end of the evaporation filter element 3 can be prevented from being soaked in the water for a long time, the whole evaporation filter element 3 can be ensured to be moist and have a large evaporation area, the humidifying efficiency can be improved, the use cleanness and the sanitation of the humidifier can be kept, and the service life of the evaporation filter element 3 can be prolonged.

Go up leaching rooms 4 and not only can let water make evaporation filter core 3 wholly keep moist in order to improve evaporation area and evaporation capacity at the circulation flow in-process, can also avoid evaporation filter core 3 directly to soak in aqueous, avoid evaporation filter core 3 to breed the bacterium and produce the peculiar smell, and then improve evaporation filter core 3's life. Therefore, the structure of the upper shower chamber 4 plays a very important role in ensuring the humidifying efficiency of the humidifier.

Go up the shower 4 including the trickle body 41 that has the cavity and can dismantle the chamber lid 42 of assembly on the trickle body 41, the shape of cavity and the shape phase-match of evaporation filter core 3, water inlet 411 sets up the lateral wall at the cavity, and a plurality of lower water holes 412 all set up the bottom at the cavity. The upper shower chamber 4 adopts a split structure of the shower body 41 and the detachable chamber cover 42, so that the shower body 41 can be conveniently cleaned regularly, and the humidifier can be kept in a clean and sanitary use state.

A surrounding plate 413 is arranged in the cavity of the water spraying body 41, the cavity is divided into an outer cavity 401 and an inner cavity 402 by the surrounding plate, a notch 4130 corresponding to the water inlet 411 is arranged on the surrounding plate 413, and a plurality of water outlet holes 412 are uniformly distributed at the cavity bottom of the outer cavity 401 and the cavity bottom of the inner cavity 402. Water flows into the outer chamber 401 from the water inlet 411, and simultaneously flows into the inner chamber 402 from the notch 4130, and then flows downwards to the evaporation filter element 3 from the uniformly distributed water drainage holes 412, so that the water drainage is uniform, and the positions of the evaporation filter element 3 can be kept in a wet state to keep better humidification efficiency.

Water baffles 414 are disposed on both sides of the notch 4130, so that the water baffles 414 can block part of the water entering the outer chamber 401 and guide the water to the notch 4130 to enter the inner chamber 402.

The outer chamber 401 and the inner chamber 402 are both annular, the outer chamber 401 has a section of first empty-avoiding water chute 4011 which is close to the water inlet 411 but is not provided with the drain hole 412, the inner chamber 402 has a section of second empty-avoiding water chute 4012 which is close to the notch 4130 but is not provided with the drain hole 412, and the first empty-avoiding water chute 4011 and the second empty-avoiding water chute 4012 are not located on the same side of the water inlet 411 at the same time. The structure can ensure that water entering the cavity cannot flow away from most of water at the lower water hole 412 close to the water inlet 411, so that no water exists in other lower water holes 412 far away from the water inlet 411, namely, the structure is favorable for enabling the positions of the upper shower chamber 4 to be uniformly drained so as to keep all parts of the evaporation filter element 3 wet.

Wherein, the water pan 2 is provided with a water receiving tank 21, and the lower end of the evaporation filter element 3 is arranged in the water receiving tank 21; a water return port 22 is provided at the bottom of the water receiving tank 21, and the water return port 22 is provided opposite to the tank port 12 of the tank 1 so that water in the water receiving tank 21 can smoothly flow back into the tank 1 from the tank port 12 through the water return port 22. Therefore, the water receiving tray 2 and the water tank 1 are not fixedly connected, and the water tank 1 is convenient to take out for water adding operation.

The diameter of the water return port 22 is not smaller than the diameter of the water inlet 411 of the upper shower 4 (for example, if the water return port 22 and the water inlet 411 are both tubular in the figure, the diameters correspond to the diameters of the pipes), so that the maximum amount of water flowing through the water return port 22 is not lower than the maximum amount of water entering the upper shower 4 through the water inlet 411.

The structure can reduce the accumulated water generated in the water receiving tank 21, not only prevent the lower end of the evaporation filter element 3 from being soaked in the water receiving tank 21, but also prevent the water receiving tray 2 from overflowing.

The water tank opening 12 is provided with a guide plate 13 corresponding to the water return opening 22, and when water in the water receiving tank 21 flows to the water tank opening 12 through the water return opening 22, the water flows back to the water tank 1 after being guided by the guide plate 13. For example, the baffle 13 is a sloping plate extending from the tank port 12 to the inside of the tank 1, and the sloping plate is located below the return port 22. The guide plate 13 provides buffering and guiding for the return water flowing out of the return water port 22, so that the water at the return water port 22 is prevented from directly falling into the water tank 1 downwards and rapidly, the return water sound can be reduced to reduce the use noise, and the overflow phenomenon caused by water splashed out of the water tank 1 when the return water falls can be avoided.
