Embodiment
The utility model is described in further detail below in conjunction with the drawings and specific embodiments:
Natural wind makes the people feel that comfortable principle is to allow people's whole body wind-engaging, and disorder is arranged slightly, though dynamic, blow continuously on people's body all the time.The utility model is implemented according to above-mentioned principle: it is a combination fan 3 that two first electric fan 1 and second electric fans 2 that are mutually angle are set.Two first electric fans 1 that are mutually angle are fixedlyed connected with second electric fan, 2 usefulness shells 31.At the above-described combination fan 3 of overlapping at least two groups of Vertical direction.At the overlapping combination fan of Vertical direction, be connected on the support 33 with screw 32.Present embodiment is that three groups of combination fans are overlapping.Its objective is that the wind that above-mentioned many group combination fans are produced by boasting bumps, and produces the wind of large size disorder.
The inclined-plane page or leaf sheet 17 of tradition blade-rotating is all to lopsidedness (seeing Fig. 6, Fig. 7), and half of blade-rotating of the present utility model 11 inclined-plane page or leaf sheet 12 sums be to lopsidedness, and second half opposite side in the opposite direction tilts, as Fig. 2, Fig. 3 and shown in Figure 4.Using method of the present utility model is: inclined-plane page or leaf sheet 12 true dip directions of first electric fan, 1 blade-rotating of each group and inclined-plane page or leaf sheet 12 true dip directions of second electric fan, 2 blade-rotatings are set to differ 90 °, see Fig. 2.Start first electric fan 1 of each group and the speed governing button 13 of second electric fan 2 then respectively, adjust first electric fan 1 of each group and the rotating speed of second electric fan 2 respectively, start first electric fan 1 of each group and the blade-rotating button 14 of second electric fan 2 then, first electric fan 1 of each group and the blade-rotating 11 of second electric fan 2 are rotated, like this, just can obtain the disorderly natural wind of larger area realistic simulation.
In state shown in Figure 2, the wind that first electric fan is produced by boasting is mainly to be to disperse to the left and right forward, and the wind that second electric fan is produced by boasting mainly is to disperse up and down forward.The wind that first electric fan and the second electric fan intermediate portion are produced by boasting can bump, and the wind after the collision is to blow to mussily on the center line 6 that is in two electric fan angles, sees Fig. 3.If the people is on the center line 6, will be subjected to up and down the wind of producing by boasting with the centre.When the blade-rotating of first electric fan turns over an angle, the blade-rotating of second electric fan also turns over an angle, such as, as shown in Figure 5, then disperse the bottom about two blade-rotatings wind direction forward direction of producing by boasting from the bottom, and disperse to top forward after the collision of the wind on top, intermediate portion bumps after-blow to center line 6.By that analogy, when two blade-rotatings turn over any one angle (for example the blade-rotating of first electric fan rotates counterclockwise, and the blade-rotating of second electric fan clockwise rotates) separately in the opposite direction, all can produce the disturbance wind of dispersing and colliding out.Owing to also have overlapping combination fan (three groups overlapping is top-priority scheme) in Vertical direction, the wind of producing by boasting between each combination fan collides mutually again and disperses, so the more traditional electric fan of wind area that the utility model is produced by boasting is many greatly, disorder is but arranged slightly, so simulated disorderly natural wind more realistically.If the rotating speed of first electric fan 1 and second electric fan 2 is different, then can produce more disorderly wind.The degree that it is suitable can be decided according to user's operation.
