Description

Radiating type natural wind electric fan

The utility model relates to a kind of electric fan, exactly, relates to a kind of radiating type natural wind electric fan.

Now, the desk fan of selling on the market, stand fan, wall fan or box fan all have common shortcoming:

1, Chui Feng scope is too little, and when not shaking the head, the same indoor people who blows to wind is blown by unalterable wind forever, and having blown for a long time can headache, blow people less than wind blow forever less than, soaked with sweat in the same old way; Though can blow to most of scope when shaking the head, blowing to will wait for a long time behind wind just can blow to for the second time, blows few many wind that stops like this, makes the people too impatient to wait, more increases fidgety.Though 2, wind speed, air quantity are had large, medium and small three kinds of selections, once selected, its wind speed air quantity is still unalterable, can not be suddenly big or suddenly small as natural wind, the time disease during Xu.

Ceiling fan for another example, though can make it that wind is often arranged, the wind speed air quantity that blows out is still unalterable, this changeless wind blows from the crown, and is of long duration, also do not feel better.And for example fan, because of the position is too low floor-dust is sucked and upwards blow out disorderly dance, seldom use now of the skirt full front of a Chinese gown of maid's soil again.

The purpose of this utility model provides a radiating type natural wind electric fan that can thoroughly improve above-mentioned various electric fan shortcomings.

The utility model is achieved in that and includes build-up member, wind-force parts, wind guide component and accent wind part, it is characterized in that: build-up member includes: a circular substrate, substrate is provided with the through hole of central shaft hole, motor pilot hole or several weight reductions, one be contained in that the substrate center hole extends downwards be used to hold the metal central siphon that lead passes, can be contained on the flexible arm of stand fan or desk fan or hang upside down on the ceiling fan arm, six roots of sensation average mark is located at upwardly extending pillar around the substrate at least; Above-mentioned wind-force parts include: a fan electromotor that uprightly is contained in substrate center, an air blast wing wheel that directly is fixed on the motor shaft, this air blast wing wheel is to be made of the bottom of an arc taper wind-guiding face shield and top a plurality of fins, adopts the duroplasts integrated injection molding; Above-mentioned wind guide component includes: a vertically installed wasp waist type air intake air duct, be equipped with the flange of outside stretching, extension around its air intake and the outlet air end opening, the chain link fence safety enclosure is housed on the air intake flange, the outlet air end flange is provided with at least six through holes, installing by the upwardly extending six roots of sensation at least of substrate pillar, and locking air intake air duct makes between the guiding face shield of its outlet air end and wing wheel bottom and forms a whole ring-type exhaust outlet that encloses; Above-mentioned accent wind part includes: the drum shape that covers on ring-type exhaust outlet periphery is transferred the wind fan housing, cover at the end central authorities be provided with one and be fixed on the gear that covers at the end, its center is provided with axis hole, be provided with the sliding bearing that is locked in after supplying above-mentioned metal central siphon to pass on the substrate in the hole, small-sized slow speed motor is housed on the substrate, its rotating shaft is stretched out below substrate, transfer fan housing to make slow rotation to drive, offering a plurality of width on barrel around the accent fan housing does not wait, the different different shape of density is straight, oblique or crooked shape opening, make the air blast wing wheel to around the wind sent, behind the barrel opening of this slow rotation, simultaneously to around send suddenly big or suddenly small, when Xu time disease, free of discontinuities and changeable natural wind simulating forever.

Above-mentioned wind-force element is the propeller blade formula, is installed in the main shaft top of fan electromotor, and the position of its paddle is positioned at the wasp waist portion of air intake air duct, the formation axial fan.

Above-mentioned wind-force element is multiple wing sheet wind wheel and propeller blade merging, sets up at least two propeller blades in being encircled in the top by a multiple wing sheet wind wheel and is formed, and constitutes axial fan.

The utility model utilizes a drum shape to transfer fan housing, cover on the periphery of ring-type exhaust outlet, the feasible small-sized motor of torsion at a slow speed that is installed on the substrate transfers fan housing to rotate by gear driven, utilizes and transfers the width difference of offering on the fan housing, the through hole that density does not wait all around, during rotation to around send Xu's disease changeable natural wind, its wind speed air quantity is changeable constantly and never interrupt, and makes the indoor cold air of can use less of hot summer, also can enjoy the happy natural wind of feeling nice and cool, both reduce people's air-conditioning sickness, saved the energy again.
