It is pointed out that the relief opening about same row is meant one group of such relief opening, the outlet that they are set at its each relief opening on the nozzle all roughly be in the perpendicular same plane of axis on; Described many row's relief openings are meant two rows and the above relief opening of two rows that is set in row, wherein, the outlet of same row's relief opening all roughly be in the perpendicular same plane of axis on, the outlet of different rows' relief openings be in the perpendicular Different Plane of axis on.

Described its row's number of many row's relief openings can be selected as required, and preferably, its row's number is 2 to drain into 6 rows.

Its Way out of each relief opening and the angle between the described axis that are in same row can be roughly the same, also can be different.

Preferably, the Way out of each relief opening of described many its same rows of row's relief opening, its different rows' the Way out of respectively arranging relief opening all roughly the same with the angle between the described axis and the angle between the described axis have nothing in common with each other.

The Way out Way out of respectively arranging relief opening all roughly the same with the angle between the described axis, its different rows of each relief opening that described many row's relief openings also can be its same rows is identical with the angle part between the described axis or all identical.

In another preferred embodiment, the Way out and the angle between the described axis of each relief opening of described many its same rows of row's relief opening are all roughly the same, its different rows' the Way out of respectively arranging relief opening and the angle between the described axis have nothing in common with each other, wherein, be arranged at and compare less from described axis postive direction its Way out of relief opening at a distance with the angle between the described axis with being arranged at from the angle between its Way out of described axis postive direction relief opening more nearby and the described axis.

Usually, the described Way out Way out of respectively arranging relief opening and the angle between the described axis all roughly the same with the angle between the described axis, its different rows of arranging each relief opening of its same rows of relief opening spent between 45 degree 0 more, preferably, its angle is between 5 degree are spent to 30.

The spacing that described many row's relief openings are separated by along described axial direction can be selected as required, usually between 5 millimeters to 100 millimeters, preferably between 10 millimeters to 50 millimeters.

Described relief opening at the width in its outlet port usually between 0.2 millimeter to 8 millimeters, preferably between 0.5 millimeter to 3 millimeters.

Described nozzle can constitute the loop of a closure, limits an opening; Also can constitute the loop of a plurality of closures, limit a plurality of openings; The cross section of its opening can be multiple shape, can be circular, oval, round rectangle, also can be the part annular, can also be other shape.

Described nozzle can be a general toroidal, and described its each row of many row's relief openings can be a general toroidal also; Described nozzle can be circular at least in part, and described its each row of many row's relief openings also can be at least in part for circular.

Described its each row of many row's relief openings can be concentric with described inner passage, also can be decentraction.

The utlity model has following good effect:

Because nozzle of the present utility model is provided with many row's relief openings, its air output increases greatly; Simultaneously, under the situation of identical air output, the noise that the utility model forms in the exhaust outlet place descends greatly.Therefore the utlity model has the advantage that air output is big, noise is low.
