Furthermore, the description of the upper, lower, left, right, front, rear, etc. used in the present invention is only relative to the mutual position relationship of the components of the present invention in the drawings.

Furthermore, unless defined otherwise, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art. The terminology used in the description herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. As used herein, the term "and/or" includes any combination of one or more of the associated listed items.

The structure and function of the air conditioning fan in the present embodiment are explained below with reference to fig. 1 to 4. As shown in fig. 2 and 4, the air conditioning fan in this embodiment includes a wet curtain filter screen 1, an atomizing unit 2, a fixing frame 3, a fan blade 4, an air guiding net 5, a housing 6, a control box 7, and a handle 8. An air inlet 61 and an air outlet 62 are respectively arranged on two opposite sides of the shell 6. The air inlet 61 and the atomization part 2 are positioned on one side of the wet curtain filter screen 1, the fan blade 4, the air guide net 5 and the air outlet 62 are positioned on the other side of the wet curtain filter screen 1, and the air guide net 5 is positioned between the fan blade 4 and the air outlet 62. Both sides of the air guide net 5 are provided with a concave part 51, the fixing plate 52 is clamped at the concave part 51, and the fixing plate 52 is fixed with the shell 6 through threaded connection, so that the air guide net 5 is fixed on the shell 6. The atomizing part 2 is fixed in the shell 6, and the fan blades 4 are fixed on the fixing frame 3. On mount 3 was fixed in shell 6, be equipped with draw-in groove (not shown in the figure) and limiting plate 31 on mount 3, wet curtain filter screen 1 goes into this draw-in groove along vertical direction card to carry on spacingly through limiting plate 31 to the lateral wall of wet curtain filter screen 1, thereby be fixed in on mount 3.

As shown in fig. 3 and 4, the atomizing unit 2 includes an ultrasonic atomizer 21 and a water tank 22, and the ultrasonic atomizer 21 is fixed on an outer side wall of the water tank 22. The water tank 21 includes a tank body 221 and a tank cover 222, and an opening 2211 is formed in a sidewall of the tank body 221. The ultrasonic atomizer 21 includes a water inlet 211 and a mist outlet 212, and the water inlet 211 communicates with the opening 2211. The water in the water tank 22 can enter the water inlet of the ultrasonic atomizer 21 through the opening 2211, and the ultrasonic atomizer 21 atomizes the entering water to evaporate and absorb heat, so that the temperature of the water mist sprayed from the mist outlet 212 is reduced. The sprayed cooled water mist is mixed with the air entering from the air inlet 61, so that the temperature of the air is reduced. In addition, ice water can be added into the water tank 22, so that the cooling effect is better. Alternatively, toilet water or mosquito repellent water may be added to the water tank 22 to achieve a mosquito repellent effect, and an air freshener may be added thereto to purify indoor air.

The mist outlet 212 of the ultrasonic atomizer 21 faces the wet curtain filter screen 1, and the water mist sprayed from the mist outlet 212 is mixed with air and then directly reaches the surface of the wet curtain filter screen 1. The wet curtain filter screen 1 absorbs large-particle water drops, controls the air circulation, and ensures that the wet curtain filter screen 1 cannot excessively absorb water, so that obvious water drops cannot appear at the air outlet 62. The wet curtain filter screen 1 can select cotton cloth or non-woven fabrics or wood pulp paper or PP flute that have self-water absorption ability, and its water absorption is strong, can prevent that the air conditioner fan from appearing the phenomenon of dripping, and can filter dust and bacterium etc. that bring in the air.

The water-air mixture of the low-temperature air and the water mist penetrating through the wet curtain filter screen 1 reaches the air guide net 5 under the driving of the fan blades 4, and the fan blades 4 rotate at a high speed to enable the water-air mixture to rotate and advance. Since such wind rotating at a high speed is likely to cause discomfort such as headache and fatigue to the user over a long period of time, the wind guide net 5 is added to the present embodiment to alleviate the discomfort. The wind guide net 5 comprises a plurality of meshes which are horizontally arranged, and the meshes are opposite to the air outlet 62. The water-air mixture which originally rotates and advances passes through the meshes of the air guide net 5 and is discharged from the air outlet 62. After passing through the air guiding net, the tendency of the water-air mixture to rotate and advance is slowed down or even eliminated, so that the wind blown out from the air outlet 62 is similar to parallel wind, the effect of natural wind is simulated, and the discomfort of a user caused by long-time use of the air conditioning fan is prevented. In addition, the wind guide net is arranged, so that wind generated by the fan blades 4 can be gathered, the wind speed at the air outlet 62 is improved, and the cooling effect is better.

In order to achieve better air guiding effect, the area of the air guiding net 5 at least needs to be larger than the air outlet area of the fan blades 4, that is, the range of the air guiding net 5 at least covers the range of the fan blades 4, so as to prevent the water-air mixture passing through the fan blades 4 from reaching the air outlet 62 from the area outside the air guiding net 5. The shape of the meshes on the air guide net 5 can be circular or polygonal, or can also be irregular. As shown in fig. 5, the mesh shape of the wind guiding net 5 in this embodiment is a hexagon, and the whole wind guiding net is in a "honeycomb" shape. If the mesh size is too small, the efficiency of the water-gas mixture passing through is low, and therefore, the radius of the mesh needs to be more than or equal to 3 mm. For polygons, the term "radius" is used herein to refer to the radius of its inscribed circle. In addition, if the thickness of the wind guide net 5 is too small, the effect of converting the rotating wind into the parallel wind is poor, and therefore, the thickness of the wind guide net 5 needs to be equal to or greater than 6 mm.

The bottom of the housing 6 is also provided with a battery accommodating cavity 63 for accommodating a battery. A PCB is arranged in a control box 7 at the top of the air-conditioning fan and used for controlling the air-conditioning fan to work. The top of the fixing frame 3 is provided with a convex block 31, the bottom of the control box 7 is provided with a groove 71, and the convex block 31 is clamped in the groove 71.

While the invention has been described with reference to a preferred embodiment, it will be understood by those skilled in the art that various changes in form and details may be made therein without departing from the spirit and scope of the invention as defined by the appended claims.
