The utility model relates to a kind of pin without blade fan, refer to that one comprises air-flow and produces head especially, this air-flow produce head is provided with high velocity air wind unit and positive/negative-pressure air-flow path without blade fan, wherein, this high velocity air wind unit ring is located at this positive/negative-pressure air-flow path surrounding, produce first side at this air-flow and form an air negative pressure district, the other side producing head at this air-flow forms an air positive pressure district, this positive/negative-pressure air-flow path is communicated with between this air negative pressure district and this air positive pressure district, this air-flow produces head and is connected with one end of breathing pipe, pressurized gas flow into this air-flow by this breathing pipe and produce in head, caisson is connected to other one end of this breathing pipe, this caisson stores high-pressure air, and form this pressurized gas when this high-pressure air of release, these pressurized gas flow into this air-flow by this breathing pipe and produce in head.
Background technique
As everyone knows, the inspiration without blade fan comes from air blades hand-drying device.The principle of air blades hand-drying device forces air to carry out " blowing " dry water on hand through an osculum, and air multiplier allows air produce by boasting from 1.0 mm wides, the otch that rotates around annulus amplifier.Because air is forced to produce by boasting from this circle, the air quantity passed through can increase original 15 times, and its speed per hour can reach 35 kilometers.The wind produced than conventional fan without the air flowing of blade fan is more steady.The air quantity that it produces is equivalent to the best fan of performance in the market.Because do not have fan sheet to carry out ' cutting ' air, user can not feel interim and impact and waveform stimulation.It allows you feel more naturally to feel nice and cool by the air stream continued.
Working principle without blade fan is: in pedestal with motor often that air intake fan base is inner, after accelerating via cyclone accelerator, air passage rates is maximum is increased about 16 times, via without blade fan fan head annular epipharynx around, it drives the air near fan head to enter fan head around power thereupon, and at full speed outwards blows out.Utilize the technology in jet aircraft engines and vehicle turbine supercharging without blade fan, suck air by the wind inlet of bottom, the impeller that the inside of annular edge hides then sprays air with circular trace, final one continual cool air stream of formation.Importantly this air flowing is more steady than the wind of conventional fan generation.The air quantity that it produces is equivalent to the best fan of performance in the market.
Although traditional possesses energy-conservation without blade fan from the analysis of its air-flow producing cause, air-flow is soft, the plurality of advantages such as safety, but cause because the power loss of cyclone accelerator part in its pedestal is excessive when practical application and need to utilize very large capacity motor can make to produce without blade fan the situation of wind energy in a small amount, if and operating noise also can be multiplied the while of utilizing large capacity motor entirety can be made to waste energy without blade fan product power ascension when concrete enforcement, and although this is also novel without blade fan before just, but one of reason be not slowly widely used.
Research tradition utilizes very large capacity motor can make to produce without blade fan the problem of wind energy in a small amount without blade fan in addition, we can find it without blade fan pedestal owing to needing to assemble numerous parts such as motor, cyclone accelerator so the sealing of its pedestal is inevitable not good, the situation of " leaking out " will inevitably be there is, and this also just tradition utilize very large capacity motor can make to produce without blade fan the another question classification of a small amount of wind energy without blade fan, described above is the major defect of prior art.
