Embodiment

Fig. 1 is the structural representation without blade fan of the present invention from device forward observation.This comprises without blade fan the ring nozzle 1 that defines central opening 17 and is arranged on the component 2 of the generation in pedestal 18 by the air-flow of nozzle 1, and nozzle 1 is arranged on pedestal 18.And with reference to figure 2, Fig. 3, Fig. 4 and Fig. 5, this ring nozzle 1 comprises housing 4 and the housing 5 of the inner passage 3 for forming reception air-flow, and housing 4 comprises inward flange 6 and outward edge 7, and housing 5 comprises inward flange 8 and outward edge 9; The internal surface of the outward edge 7 of housing 4 is fixedly connected with the outer surface of the outward edge 9 of housing 5; The inward flange 6 of housing 4 comprises fixing inward flange 10 and on-fixed inward flange 11, wherein fixingly be fixedly connected with the internal surface 14 of the outer surface 13 of inward flange 10 with the inward flange 8 of housing 5, the internal surface 14 of the outer surface 15 of on-fixed inward flange 11 and the inward flange 8 of housing 5 is separated by certain spacing and arrange and define relief opening 16.

As can be seen from Figure 1, housing 4 and housing 5 constitute the nozzle 1 that has circular interior passage, housing 4 is provided with fixing inward flange 10 everywhere, can be fixed like this and be connected, be easy to form its firm structure everywhere with the inward flange of housing 5; Also can find out, housing 4 and housing 5 also constitute four slot-shaped relief openings 16 simultaneously, and each relief opening 16 two by fixing inward flange 10 and housing 5 inward flange be fixedly connected with and the fixed connection point that formed or be fixedly connected with between face.

During work, the air-flow that component 2 produces is admitted in the inner passage 3 of ring nozzle 1, and the air-flow that inner passage 3 receives is injected by four annulus shape relief openings 16, from without blade fan outside air by from relief opening the air-flow that sprays entrainment by central opening 17, the air-flow sprayed from relief opening with formed by the air-flow entrainmented the total air flow exported forward.

Fig. 2, Fig. 3, Fig. 4 and Fig. 5 show further the detail without blade fan.Can clearly be seen that from Fig. 2 and Fig. 3, mode is fixedly connected with between the fixing inward flange 10 of housing 4 and the inward flange 8 of housing 5, being the same with the mode that is fixedly connected with between the outward edge 7 of housing 4 and the outward edge 9 of housing 5, is namely all to be fixed with the surface at an edge of housing 5 with an edge surface of housing 4 to be connected.

Can clearly be seen that from Fig. 4 and Fig. 5, the on-fixed inward flange 11 of housing 4 and the inward flange 8 of housing 5 are separated by certain spacing and arrange to form relief opening 16, more particularly, the outer surface 15 of on-fixed inward flange 11 and the internal surface 14 of the inward flange of housing 5 are separated by certain spacing and form relief opening 16.

Therefore, the fixing inward flange 10 of housing 4 and on-fixed inward flange 11 combine with the inward flange 8 of housing 5, have not only played the effect that is fixedly connected with but also have played the effect forming relief opening.In the present embodiment, fixing inward flange 10 and the on-fixed inward flange 11 of housing 4 are very similar, just the angle that formed of the main body of they and housing 4 is different, thus whole housing 4 carrys out overall manufacture easily via mould, and certainly fixing also can be dissimilar with inward flange 10 and on-fixed inward flange 11.Therefore the ingenious use on this shell rim or shell rim surface, brings performance and the very large benefit of manufacture view.

Owing to being fixedly connected with between the outer surface 13 of fixing inward flange 10 and the internal surface 14 of the inward flange of housing 5, be therefore very close to each other between outer surface 13 and internal surface 14 or almost very close to each other; And the outer surface 15 of on-fixed inward flange and the internal surface 14 of the inward flange of housing 5 are certain spacing of being separated by, be namely have certain gap between outer surface 15 and internal surface 14, in the present embodiment, the outlet port minimum in gap, this gap is about 2 millimeters.

In the present embodiment, this ring nozzle 1 is arranged as and roughly extends orthogonally about X-axis line, is fixed is connected between the fixing outer surface 13 with inward flange 10 and the internal surface 14 of the inward flange of housing 5 by binder.The manufacture of housing 4 and housing 5 uses plastic materials usually, also can use metallic material, can also use other material.

Fig. 6 shows another embodiment without blade fan of the present invention.As can be seen from the figure, the comprising support 19 without blade fan, be arranged on support 19 top nozzle 1 of the present embodiment, nozzle 1 has former and later two housings (not shown in FIG.), these two housings constitute the inner passage accepting air-flow of nozzle 1, component 2 for generation of the air-flow by described nozzle is arranged on the inner passage being arranged in middle part, and nozzle 1 has four openings 17.As can be seen from the figure, housing 4 is provided with fixing inward flange 10 at eight places, can be fixed like this be connected, to form its firm structure at eight places with the inward flange of housing 5.Also can find out, housing 4 and housing 5 also constitute eight slot-shaped relief openings 16 simultaneously, and each relief opening 16 two by fixing inward flange 10 and housing 5 inward flange to be fixedly connected with and between the face that is fixedly connected with that formed or fixed connection point.The present embodiment also has its sound construction, assembling or feature convenient for production.

Although shown and described and thought preferred embodiments of the invention at present, obviously, those skilled in the art can carry out various changes and improvements, and does not deviate from scope of the present invention as defined in appended claims.
