Abstract
The invention discloses a fan blade assembly with two air channels. The fan blade assembly comprises a shell and a fan blade body arranged in the shell. The fan blade body comprises a first fan blade assembly body and a second fan blade assembly body which are arranged from inside to outside. The first air channel is formed between the first fan blade assembly body and the second fan blade assembly body. The second air channel is formed between the second fan blade assembly body and the shell. Through the arrangement of the first fan blade assembly body and the second fan blade assembly body, forward circulation of air is accelerated. Pressure boosting is formed in the first air channel and the second air channel so that the air can pass through an air outlet of a fan at high speed. Accordingly, output of long-distance large air flow is ensured.
Description
Technical field
The present invention relates to fan technology field, be especially a kind of fan blade assembly with double air channel.
Background technology
Fan refers to that hot day takes cool apparatus electric fan so as to raw wind, is the device producing air-flow by electric drive, inside joins
The fan energising put carries out rotating the effect that chemical conversion natural wind reaches to enjoy the cool later.Fan blade is that composition fan must
Indispensable parts, and the efficiency of fan is affected very big by the shape of fan blade, i.e. fan blade can affect going out of fan
Air quantity and air-out distance, and the fan blade of the fan of prior art is all single air channel structure, there is air output little
Shortcoming with air-out distance end.
Summary of the invention
In view of the defect of above-mentioned prior art, it is an object of the invention to: provide a kind of air output big and air-out away from
From the long fan blade assembly with double air channel.
The technical solution of the present invention is: have the fan blade assembly in double air channel, including shell with outside being arranged on
Fan blade body in shell, described fan blade body includes the first fan blade assembly and the second fan blade arranged from the inside to the outside
Assembly, is formed with the first air channel, described second fan blade between described first fan blade assembly and the second fan blade assembly
The second air channel it is formed with between assembly and shell.
Further, described first fan blade assembly includes installation portion and be distributed on installation portion outer wall multiple the
One fan blade, described second fan blade assembly includes the annulus fixing with the first fan blade outer end and is distributed on annulus outer wall
On multiple second fan blades, form the first air channel, phase between adjacent two the first fan blades and the inwall of annulus
The second air channel is formed between adjacent two the second fan blades and the inwall of shell.
Applying the fan blade assembly with double air channel provided by the present invention, it provides the benefit that: fan blade body bag
Include the first fan blade assembly and the second fan blade assembly arranged from the inside to the outside, the first fan blade assembly and the second fan blade group
It is formed with the first air channel between part, is formed with the second air channel between described second fan blade assembly and shell, passes through
The acceleration air that arranges of the first fan blade assembly and the second fan blade assembly circulates forward, and in the first air channel and second
Supercharging is formed so that air at a high speed by the air outlet of fan, thus can ensure distance strong wind in air channel
The output of amount.
Accompanying drawing explanation
Fig. 1 is the overall structure schematic diagram of the present invention；
Fig. 2 is the cross-sectional schematic of the present invention；
Fig. 3 is the structural representation of the fan blade body of the present invention.
Shown in figure: 1-shell, 2-fan blade body, 21-the first fan blade assembly, 211-installation portion, 212

4-the second air channel.
Detailed description of the invention
For comparing intuitively, being fully understood by technical scheme, now just combine accompanying drawing of the present invention and carry out non-
Restrictive feature description is as follows:
As shown in Figure 1-Figure 3, there is the fan blade assembly in double air channel, including shell 1 be arranged in shell 1
Fan blade body 2, fan blade body 2 includes the first fan blade assembly 21 and the second fan blade group arranged from the inside to the outside
Part 22, is formed with the first air channel 3, the second fan blade between the first fan blade assembly 21 and the second fan blade assembly 22
The second air channel 4 it is formed with between assembly 22 and shell 1.
First fan blade assembly 21 includes installation portion 211 and multiple first wind being distributed on installation portion 211 outer wall
Leaf 212, the second fan blade assembly 22 includes the annulus 221 fixing with the first fan blade 212 outer end and is distributed on circle
Multiple second fan blades 222 on ring 221 outer wall, two adjacent the first fan blades 212 and the inwall of annulus 221
Between form the first air channel 3, form the second wind between adjacent two the second fan blades 222 and the inwall of shell 1
Road 4, is circulated forward by the acceleration air that arranges of the first fan blade assembly 21 and the second fan blade assembly 22, and
Form supercharging in first air channel 3 and the second air channel 4 so that air can at a high speed by the air outlet of fan,
Thus ensure the output of distance Wind Volume.
Certainly, these are only presently preferred embodiments of the present invention, the non-patent model the most i.e. limiting to the present invention
Enclosing, all utilization description of the invention and graphic content institute are simple for it modifies and equivalent structure change, all should be same
Within reason is contained in the scope of patent protection of the present invention.
Claims (2)
1. there is the fan blade assembly in double air channel, including shell and setting fan blade body in the enclosure, its feature
