Description
Technical field
The present invention relates to a kind of fan member, particularly relate to a kind of without blade fan.
Background technique
Traditional fan generally includes motor, fan blade, base or fixing frame, power supply etc.Switch on power, motor rotates, and the fan blade on drive motor axle rotates, and the fan blade of rotation produces air-flow, and therefore, along with heat is taken away by convection current and evaporation, in the scope that air-flow blows to, user experiences cooling effect.Now certain improvement being done to traditional fan, exactly by there being the fan of leaf to be improved to fan without leaf, also having a lot of introductions about without blade fan now.As Chinese patent: " fan (CN101749289A) ", describes a kind of fan component for the formation of air-flow, and this fan component comprises the nozzle be arranged on base portion holding apparatus, this base portion holding apparatus is for the formation of the air-flow through this nozzle.This nozzle comprises for receiving inner passage from the air-flow of base portion and mouth, and wherein air-flow is launched by mouth dress portion, and this mouth is limited by the apparent surface of nozzle, and for the spacing means of the apparent surface that separates nozzle.Nozzle generally perpendicularly around an Axis Extension to limit an opening, from fan component outside air by the air-flow launched from described mouth drag inhale by described opening.But this structure arranges motor in pedestal, driven by motor fan blade is blown into air, is then sprayed by nozzle, the structure relative complex in pedestal, and motor needs higher rotation speed to export high pressure draught, brings high noisy thus.And require high for nozzle, spacing means must be designed and prevent nozzle variant.
Summary of the invention
The invention provides a kind of structure simple, air-out effect is good, running noise low without blade fan; Solve the processing request without blade fan existed in prior art high, component is many, easily produces resonance, the large technical problem of noise.
Above-mentioned technical problem of the present invention is solved by following technical proposals: a kind of without blade fan, comprise fan body, it is characterized in that: described fan body comprises housing, at least two group fan components are provided with in housing, described fan component comprises motor and is positioned at least one fan blade outside motor, be respectively air intake passage and air-out passage at the two ends of fan component, described air-out passage is communicated with the exhaust outlet on housing.Air intake passage is connected with the intake grill on housing, and air-out passage is connected with the exhaust outlet on housing.The fan component producing wind-force is placed in housing, saves the length of air intake passage and air-out passage, thus reduce the loss of wind-force, improve air-out efficiency, nor can noise be produced because of the obstruct of too much parts or form turbulent flow.Blower fan can arrange a fan blade or multiple fan blade, need according to the difference used the quantity configuring different fan blades.
As preferably, the center of described housing is provided with through hole, and through hole two ends are vertically respectively passive intake grill and passive exhaust outlet.Housing can be an airtight ring-type, as annulus, and elliptical ring or apple form etc., or polygonal.The housing of ring-type is formed centrally a large manhole in housing, and multiple fan component surrounds a ring-type, and center is passive intake grill and passive exhaust outlet.Due to the wind-force of fan component, rough air, makes the air-flow at toroidal shell center flow, and is being divided into passive intake grill, is divided into passive exhaust outlet near frontal housing portion near rear housing section.Fan component itself has intake grill and exhaust outlet, then forms passive intake grill and exhaust outlet by the blank space at blower-casting center, makes the air-out effect of fan better.
As preferably, described housing ringwise, is provided with support in housing, and support is furnished with fan component and noise reduction assembly.Utilize the support of support to improve the fixing fastness of fan component, but also layout and the installation of fan component can be facilitated.Noise reduction assembly can absorb noise, and can form air-out passage for fan component, and multiple fan component, centered by the center of housing, is distributed on support and forms a solar or lunar halo.
