Description
Technical field
The utility model relates to fan technology fields, and in particular to circulating fan.
Background technique
Existing fan is usually blown and all is further continued for being sent with the direction of axis to increase pressure by fan blade along the direction of axis air inlet
It out, is that single wind direction or increase oscillating mechanism change wind direction, wind-engaging range is smaller, and structure is complicated.
Utility model content
The purpose of this utility model is that in view of the drawbacks of the prior art and insufficient, provide that a kind of structure is simple, design is closed
Reason, circulating fan easy to use.
In order to achieve the above purposes, the technical solution adopted by the utility model is: it include upper top cover, taper diffusion shell, on
Round metal screen frame body, round metal waistband, lower round metal screen frame body, blast fan, motor, metab, air inlet；Described is upper
The bottom periphery of top cover is fixed with round metal screen frame body, and taper diffusion shell, taper diffusion are provided in upper round metal screen frame body
The upper end of cover is fixedly connected with upper top cover；The bottom of the upper round metal screen frame body and round metal waistband, round metal waistband
Bottom is connect with lower round metal screen frame body, and blast fan is provided in lower round metal screen frame body, and motor and blast fan driving connect
It connects, the bottom of lower round metal screen frame body is fixed with metab, and the bottom of metab is provided with air inlet.
Preferably, the motor uses permanent magnetic brushless.
Preferably, the blast fan is turbine fan impeller.
Preferably, the taper diffusion shell is made of aluminum material.
The working principle of the utility model are as follows: revolving speed is adjusted using single-phase DC brushless permanent magnet motor, five aluminium is driven to close
Golden fan blade rotation, forms different wind speed, air-flow, pressure according to the variation of motor speed, this air-flow is square in parallel along motor shaft
To outflow, when the surface of continuous airflow collision taper diffusion shell, air-flow can be dispersed 360 ° without dead angle and make air-flow along cone
Shape diffusion shell surface, to external diffusion, forms a large-scale air-flow, to reach expansion air-flow utilization scope at V-type.Match
It closes turbine type fan blade and converges superpower air-flow, air-flow passes through top conical body diffusion shell again makes 360 ° of long range diffusions of air-flow, diffusion
Air-flow and the style through special two round metal screen frame bodies up and down afterwards, are chopped into dispersion, and the wind seen off is dissipated with regard to more uniform
Cloth generates to space and is suitble to people's sendible temperature air-flow, have extremely mute refrigerant effect.
After adopting the above structure, the utility model is the beneficial effects are as follows: circulating fan described in the utility model, is adopted
With taper diffusion shell, forces air-flow to change wind direction and spread obliquely upward, increase wind-engaging range, sent with 360 ° without dead range
Wind.Utilization rate of taking a breath is high, forms wind-tunnel effect, Rapid replacement indoor and outdoor air convection current, to improve using aerodynamics
The operational availability of motor, reduces energy consumption, and the utility model has many advantages, such as that structure is simple, setting is reasonable, low manufacture cost.
