Abstract
The utility model discloses a non-blade fan which comprises a wind channel and an air compression draught fan. A first lantern ring is in butt joint with a second lantern ring along the axial direction to form the wind channel, a cavity is formed between the two lantern rings after the butt joint, the first lantern ring is provided with wind outlets which are evenly installed along the circumference of the first lantern ring, the wind outlets are divided into annular inner ring wind outlets and outer ring wind outlets, and the surface of the inner side of the first lantern ring is in the state of facing to the wind outlets and being gradually enlarged. A shell of the draught fan is communicated with the wind channel, and airflow is pressed into the wind channel through the air compression draught fan and then is exhausted through the wind outlets. The wind outlets jetting the airflow directly are installed on the non-protrusion surface of the annular wind channel, so that the airflow is not attached to the protruded surface after being separated from the wind outlets, and the non-blade fan flexibly adapts to requirements of various shapes and flow directions of the airflow.
Description
Technical field
The utility model relates to a kind of fan, and is particularly a kind of without blade fan.
Background technique
Not only make efficiency is low for the protecting wire net that needs in use to arrange the cage shape with the fan of fan blade, protecting wire net, cost is high, and Safety performance can not guarantee especially children are had certain danger fully.
Also adopted without blade fan in the prior art, namely substituted early stage fan-leaf fan with annular passage, the air channel has the exhaust outlet around the air channel that points to an end, the surface that exhaust outlet has projection can produce negative pressure with the outer gas stream of the attraction annular passage the other end, thereby produces the effect that air-flow amplifies.
Above-mentioned without blade fan for the exhaust outlet projection, the shortcoming of prior art is: although the surface energy of annular exhaust outlet projection plays certain air-flow amplification, but the surface of projection needs the surface state that can reach according near the material the exhaust outlet, material and the settings such as flow velocity of air-flow, the factor that relates to is a lot, therefore often the amplification effect of air-flow is not fairly obvious in the application of reality, and the main source of air-flow remains the blower fan that is connected with the air channel; On the other hand, the needs that amplify in order to adapt to air-flow so that the exhaust outlet in air channel has single structure, can't be exported the air-flow of suitable sectional shape, the flow direction according to the actual needs.
The model utility content
The utility model is in order to overcome above-mentioned defective of the prior art, to set out the air port by the surface without projection at annular passage, adapting to neatly the requirement of various different airflow shaped, the flow direction.
For achieving the above object, it is a kind of without blade fan that the utility model provides, comprise: the air channel, it is formed along the axial direction docking by first collar and second collar, first collar, second collar are mutually corresponding annular groove, form a cavity after the docking between its two collar, first collar is provided with exhaust outlet, exhaust outlet circumferentially evenly arranges along first collar, exhaust outlet is divided into interior ring exhaust outlet and the outer shroud exhaust outlet of annular, and the surface of the annular groove inside part of first collar is the state that enlarges gradually towards exhaust outlet; The blower fan of calming the anger, fan casing and described air channel connect, and the air-flow blower fan of being calmed the anger is pressed into described air channel and discharges by described exhaust outlet.
In the technique scheme, the surface of the annular groove inside part of first collar can be the conical surface of smooth gradual change expansion.
In the technique scheme, the surface of the annular groove inside part of first collar can also be the stepped conical surface that enlarges step by step.
In the technique scheme, separated by the thin slice of cutting apart of annular between interior ring exhaust outlet and the outer shroud exhaust outlet, cut apart thin slice and be connected with the first collar one by the radially gusset along the circumferential spaced set of thin slice, the angle of inclination of cutting apart thin slice is set according to default air-out direction.
In the technique scheme, the surface of the annular groove inside part of first collar can arrange auxiliary air-outlet along circumferentially even interval.
In the technique scheme, interior ring exhaust outlet and outer shroud exhaust outlet are arranged at respectively on the transitional surface between the stepped conical surface that enlarges step by step, and respectively even interval arranges between the exhaust outlet of same ring.
In the technique scheme, be crisscross arranged between exhaust outlet corresponding to inner and outer rings, so that be not prone to mutual interference between the inner and outer rings air-out air-flow, particularly the air-flow at the inner and outer rings exhaust outlet exists in the situation of interfering.
Compared with prior art, the utility model passes through the exhaust outlet at the direct ejection air-flow of annular passage, so that adapt to neatly the requirement of various different airflow shaped, the flow direction behind the flow shedding exhaust outlet.
