Specific embodiment
For the purpose of this utility model, technical solution and advantage is more clearly understood, develop simultaneously implementation referring to the drawings
The utility model is further described in example.
Fig. 1 is the principle structure schematic diagram of the air purifier in the utility model one embodiment.Fig. 2 is Fig. 1's
A-A sectional view.Referring to Figure 1 and Fig. 2, in one embodiment, a kind of air purifier 10 may include clarifier host 20
With fairing 30.
Clarifier host 20 may include base 21 and body 22.Wherein, base 21 supports body 22, and base 21 can
Clarifier host 20 is placed in the structure of the home furnishings such as table, cabinet or office furniture to have, in order to clarifier master
The clean gas flow that machine 20 generates is covered close to the regional area where the human body of home furnishings or office furniture.Have in body 22
Element (not shown in figure 1) needed for the air cleanings such as motor and strainer, also, there is purify cavity 200 in body 22, from outside
The gas that environment flows into purify cavity 200 can be treated as clean gas flow, and from 23 row of air outlet being connected to purify cavity 200
Out.
Fairing 30 is installed at the air outlet 23 of clarifier host 20, and clarifier host 20 is defeated from air outlet 23
Clean gas flow out is rectified into multiple airflow layers of layering, also, has speed difference and pressure difference between multiple airflow layers.
In the following, the principle for forming speed difference and pressure difference between multiple airflow layers is described in detail.
The public affairs that the gas flowing continuity equation obtained in hydrodynamics according to mass conservation law can be expressed as
Formula (1):
ρ1v1A1=ρ2v2A2=c formula (1)
The formula (2) that can be expressed as in hydrodynamics for the Bernoulli equation of incompressible fluid:
P1/(ρ1g h1)+v1 2/2gh1=P2/(ρ2g h2)+v2 2/2gh2Formula (2)
It is above-mentioned in formula (1) and formula (2), ρ1And ρ2Indicate fluid density, v1And v2Indicate the flow velocity of fluid, A1And A2
Indicate that the sectional area of fluid circulating path, c indicate constant, P1And P2Indicate the pressure of fluid, g indicates acceleration of gravity, h1And h2
Indicate height of the fluid relative to datum level.
For same fluid, that is, ρ1=ρ2Situation:
By formula (1) it is found that the sectional area of fluid circulating path is bigger, the flow velocity of fluid is lower；
By formula (2) it is found that in h1And h2In equal or similar situation, the flow velocity of fluid is lower, and the pressure of fluid is just
It is higher.
Based on the above principles, fairing 30 is intended to the airflow layer of layering outflow being produced from inner ring to outer ring flow velocity from coil to coil
The speed difference successively decreased, so that the pressure of the airflow layer of outer ring is higher than the pressure of the airflow layer of inner ring.Correspondingly, the airflow layer of outer ring with
The gas pressure intensity difference of external environment locating for air purifier is also relatively small, thus, the airflow layer of outer ring resists the band of external environment
The ability that foreign gas flows into is just relatively stronger.
It is understood that the difference of the speed difference between each airflow layer can be considered opposite to fluid in actual design
In the compensation of the difference in height of datum level, alternatively, if clarifier body 20 and 30 size of fairing are sufficiently small, each airflow layer phase
Negligible influence is generated on the relationship between flow velocity and pressure for the difference in height of datum level, that is, each airflow layer phase
The difference in height of datum level can also not considered.
Fairing 30 may include multiple rectification grating rings, in fig. 1 and 2, be rectified with the first rectification grating ring 31, second
Grating ring 32, third rectification grating ring 33 and the 4th rectification grating ring 34 are for totally four grating rings.
Multiple honeycomb screen circular layers fold ring set to form multi-turn air duct, it may be assumed that
The inside of first rectification grating ring 31 forms the first air duct 310；
Second rectification 32 ring set of grating ring is in the outer ring of the first rectification grating ring 31, also, the second rectification grating ring 32 and first whole
Flow the second air duct 320 that closed circular is formed between grating ring 31；
Third rectifies 33 ring set of grating ring in the outer ring of the second rectification grating ring 32, also, third rectification grating ring 33 and second whole
Flow the third air duct 330 that closed circular is formed between grating ring 32；
4th rectification 34 ring set of grating ring is in the outer ring of third rectification grating ring 33, also, the 4th rectification grating ring 34 and third are whole
Flow the 4th air duct 340 that closed circular is formed between grating ring 33.
The multi-turn air duct 310,320,330 that ring set is formed is laminated based on above-mentioned multiple rectification grating rings 31,32,33 and 34
And 340, the air-flow for flowing into fairing 30 from the air outlet 23 of clarifier body 20 can be through multi-turn air duct 310,320,330
And 340 layering outflow.
Also, cross-sectional expansion rate of each circle air duct 310,320,330 and 340 in air current flow direction is from inner ring to outer
From coil to coil is enclosed to be incremented by, it may be assumed that
The sectional area in the first air duct 310 is from inlet air side to air side with cross-sectional expansion rate Rate1 gradual change；
The sectional area in the second air duct 320 is from inlet air side to air side with cross-sectional expansion rate Rate2 gradual change；
The sectional area in third air duct 330 is from inlet air side to air side with cross-sectional expansion rate Rate3 gradual change；
The sectional area in the 4th air duct 340 is from inlet air side to air side with cross-sectional expansion rate Rate4 gradual change；
Also, Rate4 > Rate3 > Rate2 > Rate1.
Wherein, cross-sectional expansion rate refer to air duct air side area of section compared to close to clarifier body 20 inlet air
The growth rate of the area of section of side.In actual design, the cross-sectional expansion rate in each air duct is possible to entirely indicate area of section
The value of positive growth, it is also possible to which a part of cross-sectional expansion rate is to indicate the value of area of section negative growth, also, indicate section face
The value of product positive growth is necessarily higher than the value for indicating area of section negative growth.
Formula (1) as previously mentioned, the cross-sectional expansion rate in air duct is bigger, flows through the flow velocity rate of descent of the gas in air duct just
It is bigger, thus the area of section in either all air ducts is designed to positive growth, or allows the area of section in part air duct negative
Increase, if respectively cross-sectional expansion rate of the circle air duct 310,320,330 and 340 in air current flow direction from inner ring to outer ring by
Circle is incremented by, and can be produced from the speed difference that inner ring successively decreases to outer ring flow velocity from coil to coil to the airflow layer of layering outflow.
Moreover, multiple rectification grating rings 31,32,33 and 34 arranged concentric in this embodiment, therefore, each air duct outflow
Airflow layer is essentially identical compared to the height equivlent of datum level (such as bottom surface of base 21), that is, the airflow layer of each air duct outflow
Difference in height compared to datum level can be ignored, thus, the gas pressure intensity of the airflow layer of outflow is layered from inner ring to outer
Flow velocity from coil to coil is enclosed to be incremented by.
It is relatively small accordingly, due to the flow velocity of the airflow layer (that is, the airflow layer flowed out from the 4th air duct 340) of outer ring, because
And the gas pressure intensity difference of external environment locating for the airflow layer and air purifier of outer ring is also relatively small, thus, the airflow layer of outer ring
The ability flowed into foreign gas for resisting external environment is just relatively stronger, forms anti-doping protection with the airflow layer to inner ring,
And then the clean gas that can reduce air purifier output is influenced by anti-mix of the impurity in external environment, is thus improved clean
Gas is by the received efficiency of human body.In addition, each airflow layer of layering outflow is relatively orderly, to advantageously reduce in external environment
The air turbulence of formation, it could even be possible to achieving the effect that zero wind sense in periphery orientation.
It can further be seen from figure 1 that fairing 30 further includes fixed rib 35, multiple rectification grating rings 31,32,33 and
34 are fixedly connected by fixed rib 35, also, multiple fixed ribs 35 be angularly distributed and along multiple rectification grating rings 31,32,
33 and 34 radial direction extends.Fig. 1 be by taking four of 90 degree of intervals fixed ribs 35 as an example, but can not in practical application
It is limited to this.
In addition, from figure 2 it can be seen that the rectification grating ring of outmost turns, i.e., the 4th rectification grating ring 34 enter what air-flow flowed into
Wind side forms the detachable interface 36 docked with the air outlet 23 of clarifier host 20, for example, the detachable interface may include
The stable connections such as screw thread and/or buckle and demountable structure.
Fig. 3 is the schematic diagram of the section structure of the fairing of air purifier shown in Fig. 1.As shown in figure 3, multiple whole
Stream grating ring 31,32,33 and 34 by the inclination and offset of ring wall in radial directions make each circle air duct 310,320,330 and
The 340 cross-sectional expansion rate in air current flow direction is incremented by from inner ring to outer ring from coil to coil.
It in Fig. 3, is all inclined outwardly in radial directions partially with the ring wall of each rectification grating ring 31,32,33 and 34
For shifting, specifically, the inclination and offset angle of the ring wall of multiple rectification grating rings 31,32,33 and 34 in radial directions is in
Circle to outer ring from coil to coil increases, and the inclination and offset angle difference of the adjacent rectification grating ring of every two increases from inner ring to outer ring from coil to coil, also,
The inclination and offset angle difference of the adjacent rectification grating ring of every two is all larger than the inclination and offset angle of the first rectification grating ring 31 of innermost circle,
That is:
The ring wall of first rectification grating ring 31 is β relative to the inclination and offset angle of axis direction1, to be formed from inlet air side extremely
Air side is with β1For the cross-sectional expansion of expansion angle；
The ring wall of second rectification grating ring 32 is β relative to the inclination and offset angle of axis direction2, to be formed from inlet air side extremely
Air side is with α1For the cross-sectional expansion of expansion angle, wherein β2> β1, α1For β2-β1；
The ring wall of third rectification grating ring 33 is β relative to the inclination and offset angle of axis direction3, to be formed from inlet air side extremely
Air side is with α2For the cross-sectional expansion of expansion angle, wherein β3> β2, α2For β3-β2；
The ring wall of 4th rectification grating ring 34 is β relative to the inclination and offset angle of axis direction4, to be formed from inlet air side extremely
Air side is with α3For the cross-sectional expansion of expansion angle, wherein β4> β3, α3For β4-β3；
Also, β1<α1<α2<α3。
As a result, the inclination and offset angles of multiple rectification grating rings 31,32,33 and 34 can make each circle air duct 310,320,
330 and 340 expansion angle increases from inner ring to outer ring from coil to coil, thus, so that each circle air duct 310,320,330 and 340 is existed
Cross-sectional expansion rate in air current flow direction is incremented by from inner ring to outer ring from coil to coil.
In addition, in multiple rectification grating rings 31,32,33 and 34, the first rectification grating ring 31, the second honeycomb screen of non-outmost turns
The outer diameter of ring 32 and third rectification grating ring 33 can be waited than being incremented by, that is, the collar extension diameter of the inlet air side of the first rectification grating ring 31
For d, the collar extension diameter of the inlet air side of the second rectification grating ring 32 is 2 times of d, and third rectifies the collar extension diameter of the inlet air side of grating ring 33
It is 3 times of d, so that the sectional area of the first air duct 310, the second air duct 320 and third air duct 330 in inlet air side is equal, thus
Realize that the flow of clean gas flow conveys evenly distributing in the first air duct 310, the second air duct 320 and third air duct 330.
4th rectification grating ring 34 of outmost turns is formed by the 4th air duct 340 and is more biased towards in formation and external environment pressure difference
Airflow layer is isolated in minimum protection, therefore, needed for gas flow can be less slightly, correspondingly, the 4th rectification grating ring 34 is compared
It is incremented by waiting than incremental steps, phase between differential other rectification grating rings that can be slightly less than non-outer ring in third rectification grating ring 33
Ying Di, area of section of the 4th air duct 340 in inlet air side can be less than the first air duct 310, the second air duct 320 and third air duct
330 inlet air side area of section.
For example, the collar extension diameter of the inlet air side of the first rectification grating ring 31 can be 40mm, the inlet air of the second rectification grating ring 32
The collar extension diameter of side can be 80mm, and the collar extension diameter that third rectifies the inlet air side of grating ring 33 can be 120mm, the 4th honeycomb screen
The collar extension diameter of the inlet air side of ring 34 can be 150mm.Also, the ring wall thickness of each rectification grating ring 31,32,33 and 34 exists
In the range of 1.5mm-2mm, each axial dimension for rectifying grating ring 31,32,33 and 34 can be set as 50mm.
It is understood that being located at area of section of the 4th air duct 340 of outmost turns in inlet air side may be set to be
In the area of section of the first air duct 310, the second air duct 320 and third air duct 330 in inlet air side.That is, the 4th rectification grating ring 34
Compared to third rectification grating ring 33 be incremented by it is differential can be equal to non-outer ring other rectification grating rings between etc. compare incremental steps.
For example, the collar extension diameter of the inlet air side of the 4th rectification grating ring 34 may be 160mm.

Spreading rate from inner ring to outer ring from coil to coil be still incremental so that layering outflow airflow layer gas pressure intensity from inner ring extremely
Outer ring flow velocity from coil to coil is incremented by.Also, on this basis, the first air duct 410 of innermost circle produces class to the airflow layer of innermost circle
It is similar to accelerate the progradation of output, to enable the innermost circle airflow layer for being most not easy to receive external environment doping influence with more
High flow velocity output.
As the extension of structure as shown in Figure 4, in the second honeycomb screen of the first rectification grating ring 41 and time inner ring of innermost circle
