The mist concentration is higher as the mist discharge port 111 is closer, and therefore the mist concentration is lower as the upper end of the housing 21 is closer. Increasing the length of the mist barrier 217 may intercept more mist, and therefore the length of the mist barrier 217 at the upper end is greater than the length of the mist barrier 217 at the lower end, which may enable the mist to be evenly divided, i.e., the amount of mist flowing out from each of the mist outlet ports 214 is substantially the same, so that the mist can be evenly distributed at the second front wall 2152.

The mist outlet 214 is formed between the second plate 2183 and the mist barrier 217, and thus, the width of the mist outlet 214 may be set by adjusting the interval between the second plate 2183 and the mist barrier 217, for example, the mist outlet 214 may be set in a narrow shape to form a mist squeezing effect so that the mist may be blown farther.

The housing 21 further includes a mist guide plate 219, and the mist guide plate 219 is disposed between the first mist passage 2123 and the second mist passage 2125 and opposite to the mist inlet 2121 to guide the mist entering from the mist inlet 2121 to the first mist passage 2123 and the second mist passage 2125, respectively. The mist guide plate 219 is disposed at the lower end of the mist barrier 217, such that the mist enters the mist channel 212 from the mist inlet 2121, passes through the mist guide plate 219, enters the first mist channel 2123 and the second mist channel 2125 through the guiding function of the mist guide plate 219, flows to the mist barrier 217, and finally flows out from the mist outlet 214. The mist guide plate 219 can guide the mist to a longer distance from both sides, and prevent the mist from flowing to the first mist barrier 217, and thus all flowing into the first mist outlet 214, resulting in uneven mist outlet. Wherein the first is defined by the flow direction of the mist, and the first, second and third are in this order along the flow direction of the mist.

The mist guiding plate 219 may have a symmetrical structure, for example, the mist guiding plate 219 may be symmetrical about an axis of the mist inlet 2121 to achieve uniform mist guiding, so that the mist is uniformly distributed in the mist channel 212 to achieve uniform mist outlet.

The housing 21 further includes a circular bottom plate 210, the circular bottom plate 210 is disposed at the bottom of the front housing 215, the circular bottom plate 210 is accommodated in the groove 1529 of the top surface 1521, and the circular bottom plate 210 is locked to the housing 15 by screws, so that the housing 21 and the housing 15 can be fixedly connected.

The fan wheel 23 is rotatably disposed in the air duct 211 to form an air flow, and the air flow flows out of the housing 21 through the air outlet 213 to drive the mist flowing out from the mist outlet 214. In the present embodiment, the impeller 23 has a through-flow structure. In other embodiments, the fan wheel 23 may also be an axial flow structure, which may be sufficient for the purpose of forming an air flow.

The air deflector 25 is disposed between the front casing 215 and the rear casing 216, for example, the air inlet 2162 and the air outlet 213 are respectively disposed at two opposite sides of the air deflector 25, so that the air flow can enter the interior of the housing 21 from the air inlet 2162, and then flow out from the air outlet 213 by the air deflecting action of the air deflector 25. In the present embodiment, the air guiding plate 25 has a substantially arc-shaped plate structure.

The air outlet assembly 20 further includes a temperature adjustment sheet 27, and the temperature adjustment sheet 27 is disposed in the air duct 211 and can adjust the temperature of the air flow in the air duct 211. The temperature adjusting sheet 27 may be a semiconductor cooling sheet, and the temperature adjusting sheet 27 may be adjusted to a cooling mode or a heating mode as needed. For example, when warm air is required, the semiconductor cooling fins may be switched to a heating mode to heat the air flow in the air duct 211, so that the humidifying fan 1 blows out the warm air. Otherwise, the semiconductor refrigerating sheet can be adjusted to a refrigerating mode.

Referring to fig. 7 and 8, in an embodiment, a humidifying fan 3 is further provided, which is different from the humidifying fan 1 in that a partition plate 218 is not disposed in a front case 315 of the humidifying fan 3, each fog blocking plate 317 includes a first blocking portion 3171, a second blocking portion 3172 and a third blocking portion 3173, the second blocking portion 3172 is connected between the first blocking portion 3171 and the third blocking portion 3173, and the first blocking portion 3171 and the third blocking portion 3173 are respectively bent downward from two ends of the second blocking portion 3172 and located in the fog channel 212. Gaps are formed between two adjacent first blocking portions 3171 and between two adjacent third blocking portions 3173, and the gaps form the mist outlet 314, so that mist can enter between two adjacent second blocking portions 3172 through the gaps.

Between two adjacent fog blocking plates 317, an opening 3174 is formed between the first blocking portion 3171 and the third blocking portion 3173 of the upper fog blocking plate 317, and the second blocking portion 3172 of the lower fog blocking plate 317 is located in the opening 3174 to reduce the fog outlet 314, so that a fog squeezing effect is formed, and fog is further carried.

In this embodiment, an air outlet 313 is further disposed between two adjacent second stopping portions 3172, and the airflow formed by rotation of the fan wheel 33 can bring the mist farther away when flowing out of the housing 31 through the air outlet 313, so as to achieve remote humidification and expand the humidification range.

In summary, the humidifying fan 1 according to the present invention can achieve a large mist generation area and large mist amount humidification by forming the mist path 212 in the side wall of the housing 21, and the mist path 212 is separated from the fan wheel 23 and other structures, so that mist generation is not affected, and the airflow generated by the rotation of the fan wheel 23 can further move the mist to achieve long-distance humidification, thereby widening the humidification range.
