The shape of described nozzle can be circular, oval, can be that part circular, part are oval, can also be other shape.
Describedly without blade fan, conventionally can increase by the technology of shaking the head of existing fan the coverage area of exported wind.
Described can be desk fan without blade fan, can be wall fan, can be ceiling fan, can be flooring fan, can also be the fan of other type.
A second aspect of the present invention be to provide-kind for the nozzle without blade fan, this kind of nozzle, it is characterized in that, described nozzle comprise inner passage for accepting air-flow, for launch air-flow relief opening, there is the porous slab of a plurality of perforation and the first housing and the second housing that forms inner passage; Described porous slab is arranged in inner passage, and for reinforcing inner passage and noise attenuation, described porous slab becomes whole with the first housing with a housing in the second housing, and contacts with another housing in the first housing and the second housing; Described nozzle limits at least one opening, from the air without blade fan outside, by the air-flow of launching from relief opening, is entrainmented by described opening.
The outlet of described relief opening adopts slot-shaped outlet conventionally, described relief opening at the width in its outlet port conventionally between 0.5mm to 5mm; The Way out of described relief opening and the angle of axial direction are less than 20 degree conventionally, are preferably less than 10 degree.
Accompanying drawing explanation
Figure l is the schematic diagram without blade fan of the present invention.
Fig. 2 is the side view without blade fan shown in figure l.
Fig. 3 is the sectional view intercepting along the A-A line without blade fan shown in figure l.
Fig. 4 has shown the front schematic view after the porous slab in Fig. 3 amplifies.
Embodiment
Figure l is that Fig. 2 is the side view without blade fan shown in figure l from the structural representation without blade fan of the present invention of device forward observation, and Fig. 3 is the sectional view intercepting along the A-A line without blade fan shown in figure l, and Fig. 4 has shown the details of porous slab.From Fig. 1 to Fig. 4, can find out, this comprises base 1 and is arranged on the nozzle 2 on base 1 without blade fan; Base 1 comprises base portion 3 and main body 4, holds the device for generation of the air-flow by nozzle in main body 4; The described device for generation of the air-flow by nozzle comprises impeller chimney 13, is positioned at the impeller 14 of impeller chimney and the motor 15 of drives impeller rotary work; Nozzle 2 comprises inner passage 7, relief opening 8, has the porous slab 11 of a plurality of perforation 12 and the first housing 9 and the second housing 10 that forms inner passage 7, and wherein the first housing 9 is surrounded by the second housing 10 substantially; Porous slab 11 is substantially ring-type, and be arranged in and be roughly annular inner passage 7, porous slab 11 and the first housing 9 integral body, and contact with the second housing 10, make like this inner passage 7 being formed by the first housing 9 and the second housing 10 be not easy distortion, while is due to the existence of porous slab, the noise transmitting in the inner passage of decaying; Nozzle 2 defines one and is positioned at central opening 6.
