Further, the cross section of described air-flow guidance field is roughly horn-like, and its two relative side surfaces form two air flow guide surface that outside air is guided.
Further, described air flow guide surface can be inclined-plane and vertical plane combination, can be also single ramp or single inner sunken face, can also be outer convex surface and vertical plane combination.
Further, the width of the wide opening in described rear end is 6～10 times of width of inswept opening.
Further, described air-flow path is separated into the first air-flow path and the second air-flow path by air-flow guidance field, described nozzle body surface is provided with the two row relief opening corresponding with the first air-flow path and the second air-flow path respectively, and the inswept opening of described air-flow guidance field is just in time between two row relief openings.
Further, described the first air-flow path and the second air-flow path can be set to connectivity structure, also can be set to mutually not connectivity structure.
Further, described receiving port is located at nozzle body bottom, described the first air-flow path and two vertical passageways of the second air-flow path for being connected with receiving port upper end.
Further, the spacing between described two row relief openings is 2～150mm.
Further, the spacing between described two row relief openings is 10～50mm.
Further, described nozzle body is set to circular cylindrical cavity.
The beneficial effects of the utility model are:
First, air-flow guidance field inswept, the wide horn-like structure in rear end, can guiding outside air by play multiplication air-flow velocity effect, the air that can effectively attach nozzle periphery generates high velocity air, and guide and concentrate between two row relief openings, mix with the basic air-flow ejecting from relief opening together and carry fast forward, not only accelerated the jet velocity of air-flow, improve air quantity, and can also keep the equalization stable of air-flow output.
Secondly, there are two row side by side and close on the relief opening of setting, during work, two strands of air-flows that eject by this two row relief opening, merge into one air-flow in the place ahead of nozzle, have accelerated the jet velocity of air-flow, improve effective air supplying distance, can realize fast nice and cool user's object., compare with existing ring nozzle meanwhile, when motor speed equates, can increase air output, equal air output can reduce motor revolution, cuts air and the noise that produces while reducing impeller High Rotation Speed.
Therefore moreover the air-flow path of nozzle is set to two vertical passageways, making the trend of air-flow in passage is single vertical direction, can promote air-flow being uniformly distributed in two passages, and then the uniformity while guaranteeing jet-impingement.
Finally, without blade fan designs of nozzles, be roughly cylinder type, the utilization area taking is in use little, saves usage space, and convenient for collecting, saves parking space.
