Referring to fig. 1 to 5, an embodiment of the present disclosure provides a fan blade, including: the blade body 10 is of a circular structure, a plurality of fan-shaped areas 101 in a wavy structure are formed on the end face of the blade body 10, wave crests 103 and wave troughs 104 of the wavy structure of each fan-shaped area 101 are arranged at intervals along the circumferential direction of the blade body 10, and the symmetrical center lines of the fan-shaped areas 101 are arranged along the radial direction; wherein, a water storage space is defined between adjacent wave crests 103 and wave troughs 104, and under the condition that the blade body 10 rotates, the blade body 10 lifts water in the water storage space to form a water curtain.

By adopting the fan blades provided by the embodiment of the disclosure, the wave crests 103 and the wave troughs 104 are circumferentially arranged at intervals, so that water raised by the fan blades is diffused outwards along the radial direction of the blade body 10, the coverage range of the formed water curtain is enlarged, and the water raised from the water storage space is continuously blocked by the wave crests 103, so that the volume of water drops in the formed water curtain is smaller, and the atomization effect of the water curtain is improved; thereby behind the air current water curtain, can not only purify the cleanness to the air, the less water droplet of volume blows off to indoor along with the air current motion under the effort of air current moreover, can improve the humidity of air, and then promotes user experience.

The blade body 10 is of a circular structure, i.e., the blade body 10 may be a circular plate. The blade body 10 is formed by a plurality of sectors 101 connected in series. Both end surfaces of the blade body 10 may be provided with a wave structure. For convenience of description and distinction, the two end surfaces of the blade body 10 are defined as a first end surface and a second end surface, respectively. The wave troughs 104 on the first end face of the blade body 10 are arranged opposite to the wave crests 103 on the second end face, and the wave crests 103 on the first end face of the blade body 10 are arranged opposite to the wave troughs 104 on the second end face.

The water storage space defined between the adjacent wave crests 103 and wave troughs 104 stores a certain amount of water, under the condition that the blade body 10 rotates, the water stored in the wave troughs 104 moves along with the rotation of the blade body 10, and the water flow moves along the radial direction of the blade body 10 under the obstruction of the wave crests 103 and then moves along the circumferential direction of the blade body 10 under the centrifugal action.

Wherein, when water along the circumferential motion of blade body 10, the water continuous hindrance of each crest 103 of flowing through for the water droplet in the rivers constantly breaks, and the volume constantly reduces, thereby the water droplet is small in the water curtain of formation, has improved the atomization effect of water curtain.

When the air was when flowing through the water curtain, the air passed the water curtain, and the water droplet in the water curtain is small, can reduce the hindrance effort to the air on the one hand, and particulate matter, bacterium, virus etc. that contain in the on the other hand air can be adsorbed or dissolve in the water curtain to the realization is to the cleanness of air.

Optionally, a plurality of water pumping holes 20 are provided on the blade body 10, and the water pumping holes 20 are through holes penetrating through the end surface of the blade body 10.

Under the condition that the blade body 10 rotates, part of water can be accumulated in the water lifting holes 20, the accumulated water in the water lifting holes 20 moves along with the rotation of the blade body 10 and is separated from the water lifting holes 20 under the centrifugal action, the water separated from the blade body 10 is converged in multiple directions with the water lifted from the wave troughs 104 to form a water curtain, the formed water curtain effect is better, and the air purification effect is further improved.

Optionally, the centre line of the lift holes 20 is parallel to the centre line of the blade body 10.

Alternatively, the water emitting holes 20 may be circular holes, or prismatic holes. The shape of the water-emitting holes referred to herein is not limited to circular holes or prismatic holes. The circular or prismatic holes are chosen for ease of machining. The water lifting holes can also be in other shapes except for circular holes or prismatic holes, and are not described in detail herein.

It should be noted that the number and size of the water-lifting holes 20 are designed and produced according to actual conditions to ensure the stability of the fan blades and the water curtain effect formed by the rotation of the fan blades.

Optionally, the wave crests 103 and the wave troughs 104 of the sector 101 are both configured with the water lifting holes 20, wherein the water lifting holes 20 located at the wave crests 103 and the water lifting holes 20 located at the wave troughs 104 are alternately arranged.

Through all being constructed with the lifting hole 20 at crest 103 and trough 104, under the pivoted condition of blade body 10, the water that the water multi-angle multi-direction that the water that the lifting hole 20 that is located crest 103 was raised and the water that the lifting hole 20 that is located trough 104 was raised mixes and forms the water curtain, not only can make the atomization effect of water curtain good, but also can increase the effective width of water curtain, the extension air gets into the clean time of water curtain to the outflow water curtain promptly to improve purifying effect.
