Description

A kind of portable type hand blower fan

Technical field

The utility model relates to a kind of Portable wind fan structure, relates in particular to the portable type hand blower fan that a kind of volume is small and exquisite, blast is high, air mass flow is large, wind speed is adjustable.

Background technique

On market, have common electric fan now now, such as desk-top, floor model, wall hanging, suspended ceiling, the leaf fan of the various ways such as car ship borne type, these fan volumes are larger, weight ratio is heavier, the power supply that they adopt usually is the civilian or industrial Ac of 220V or 380V or car and boat live bottle, and these power supplys must have electrical network and portable generator generating to provide support, and do not set up the place of electrical network and portable generator platform and can't use, thereby be mainly used in the fixed-sites such as family, factory, can't carry.

When people go out or do not need to use these large volume electric fans, general solution is traditional fan or carries the various various mini fans that gradually occur, traditional fan uses not only effort, there are simultaneously wind-force deficiency and inhomogeneous shortcoming, as for various hand in the market, take mini fan, have at least the deficiency of following several respects: (1) dryelement cell that use drive more, axial flow of air, blast fan is common plastic impeller, rotating speed is very low, blast is very low, air quantity is very little, per minute only have several a few decaliter air quantity that are raised to, can't meet the human-body radiating requirement, along with the dryelement cell voltage attenuation, the wind pressure and wind speed air quantity is and then decay together, more and more a little less than, until stop.(2) mostly various mini fan is the mini version of traditional big fan, what mostly adopt is the paddle wheel fan of air along the impeller axial flow, suction port and exhaust outlet are all in axial rectilinear direction, air inlet on one side, give vent to anger on one side, hang on the person, keep air inlet on one side smooth and easy, another side is given vent to anger and must be stopped.Vice versa.Be unfavorable for very much carrying and brush body temperature lowering.(3) be limited to above-mentioned (2) point described, fan needs hand-held use more, can't be linked with oneself, clip, uses cumbersome.
