Description
The application is Application No. 201080070363.2 (international application no PCT/US2010/050934), filing date
JIUYUE in 2010 30 days, the divisional application of application of invention entitled " mixing arm ".
Technical field
The present invention relates generally to agitator, and more particularly, to a kind of blade used in agitator.
Background technology
The beverage being popular now is these beverages of so-called " frost " beverage or Sorbet, the most generally can wrap
Including a part of liquid of a certain amount of ethanol and/or seasoning mixing beverage and a part of ice can be at agitating device or have vaned
Agitator mixes, is used for being formed almost slush shape beverage.
Generally, mixing arm can have two blade profile extended in the opposite direction from blade body.
Two blade profile each can be equipped with cutting surfaces along their leading edge.In the running of agitator, stir
Mix device blade to rotate around rotary shaft, and cutting surfaces can cut through the working media being arranged in agitator vessel.
Generally, blade profile can be angled relative to blade body so that blade profile has the angle of attack.The angle of attack changing blade profile can be used
In the axial flowing controlling working media.
Make blade profile relative to the angled importance of blade body to understand, it is necessary to understand rushing relative to wing
Angle.For wing, the angle of attack can be determined relative to the string of a musical instrument of wing.The string of a musical instrument is the line drawn from the leading edge of wing to trailing edge, and
And the angle of attack is the angle formed between the string of a musical instrument and horizontal plane.When the angle of attack of wing changes, wing " lifting " of being formed also becomes
Change.
Such as, when wing has high incidence, flow media may impinge upon on the lower surface of wing.Therefore, the angle of attack can
To cause lower surface to make flow media offset away from wing.Side-play amount is relevant to the orientation of wing.That is, when the bigger hour offset of the angle of attack
More, and when the less hour offset of the angle of attack is less.This skew is formed about low pressure at the upper surface of wing.
Such as, lower surface may be located remotely from the path of wing and promotes flow media, and thus near the upper surface of wing
Cause the disappearance of flow media.Owing to lacking flow media, therefore it is being provided about low pressure at upper surface, and these low pressure is being produced
Raw above-mentioned lifting.Equally, the higher angle of attack produces low pressure to produce bigger lifting near upper surface, and the relatively low angle of attack
Low pressure is produced to produce less lifting near upper surface.
The lifting produced by the angle of attack of above-mentioned wing can be equal with the axial flow produced by the angle of attack of blade profile.So
And, different from above-mentioned wing, (relative to its leading edge) " can be distorted " by blade profile forward or backward along its longitudinal length
Determine the angle of attack of blade profile.This distortion determines upper surface or the lower surface having how many working media to clash into blade profile.Do not having
In the case of the shock of working media, the angle of attack can be zero effectively.Such as, if blade profile is upwardly or downwardly at an angle of
(but not being distortion forward or backward), then working media will not clash into blade profile, and the angle of attack of this blade profile will effectively
Ground is zero.
For forming the necessary angle of attack, can the twisted blade wing forward or backward.When the twisted blade wing forward, working media
Clash into upper surface, and when the twisted blade wing backward, working media clashes into lower surface.Twist angle determines shock amount, and axle
To flow, and direction of twist (relative to leading edge forward or backward) determines the direction of axially flowing.
Such as, if blade profile distorts forward relative to its leading edge, then working media will clash into the upper surface of blade profile,
And low pressure will be produced near lower surface, thus working media will be moved to from the top of mixing arm lower section.At another
Individual aspect, if blade profile distorts backward relative to leading edge, working media will clash into lower surface, and will be near upper surface
Formed low pressure, thus by working media from the lower section traction of mixing arm to top.No matter which kind of mode, all passes through blade profile
Cutting pattern traction working media.
Traditionally, if it is desired to process or stir less amount of working media, the work of such as 6 ounces to 12 ounces is situated between
Matter, operator will use less container or have the container of narrow base portion.Additionally, if it is desire to process or stir larger amount of
Working media, such as from 12 ounces to the working media more than 48 ounces, operator will use bigger container or have width
The container of base portion.But, due to the container of narrow base portion processes the amount of material more than 32 ounces may be problematic, therefore use narrow
The container of base portion processes larger amount of working media and is not likely to be preferable.On the contrary, it is the most applicable.Wide base portion is utilized to hold
It may also be undesirable that device processes small amount of working media.

Inclined-plane can be correspondingly become with the second wing tip 46 and sharp by making first blade profile the 30, second blade profile the 32, first wing tip 44
Change.
First blade profile leading edge 58 and the first wing tip leading edge 60 can be formed and permissible along the side of the first blade 12
Cutting responsibility is shared in described side along blade 12.Second blade profile leading edge 58 and the second wing tip leading edge 62 can be along first
The another side of blade 12 is formed and can share cutting responsibility along the described side of blade 12.Therefore, when the first blade
12 around its rotary shaft rotate counterclockwise time, the leading edge 56,60 that is positioned on the side of the first blade 12 and be positioned at first
Leading edge 58,62 on the opposite side of blade 12 can cut through the working media being placed in agitator vessel.
Owing to the first blade profile 30 can orient relative to body part 28 asymmetrically with the second blade profile 32, therefore
One blade 12 can have two kinds of cutting patterns.First cutting pattern can be substantially plane and the first leaf can be passed through
The leading edge 56 of the sheet wing 30 is formed with the leading edge 60 of the first wing tip 44.Second cutting pattern can be substantially truncated cone shape and can
Formed with the leading edge 62 by the leading edge 58 of the second blade profile 32 with the second wing tip 46.
After first blade profile 30 can include at least one trailing edge 64, and the second blade profile 32 can include at least one
Edge 66 (Fig. 5).Trailing edge 64,66 can be any suitable shape, size, type or structure.Trailing edge 64,66 can be positioned at phase
Answer any suitable position in blade profile 30,32, be such as positioned at the side (Fig. 5) of the respective vanes wing 30,32.Such as,
Trailing edge 64,66 can be positioned near corresponding wing tip 44,46.
First blade profile 30 can include the first ala 68, and the second blade profile 32 can include the second ala 70.The wing
Lobe 68,70 can be any suitable shape, size, type or structure, the most generally rectangular configuration.Ala 68,70 can
To be positioned at any appropriate position on the respective vanes wing 30,32, generally the most relative with the position of corresponding leading edge 56,58
(Fig. 3-Fig. 7).Such as, the first ala 68 and the second ala 70 can be correspondingly from the first blade profile 30 and the second blade profile 32
Trailing edge 64,66 is at an angle to outer extension.Ala 68,70 can the most correspondingly include upper surface 72,76 and lower surface
74、78.The lower surface 74,78 of ala 68,70 can orient with obtuse angle relative to the lower surface 38,42 of blade profile 30,32.
Ala 68,70 could be arranged to not consider that the first blade profile 30 and the angle of attack of the second blade profile 32 control work and be situated between
The axial flowing relative to the first cutting pattern with the second cutting pattern of matter.Such as, ala 68,70 can be with any suitable angle
Degree location, is at an angle of, the most downward or upward correspondingly to increase upper surface 36,40 and the lower surface 38,42 of blade profile 30,32
Corresponding effectively angle of heel (camber).
Cause the increase of effective angle of heel owing to increasing ala 68,70, therefore can produce low pressure by ala 68,70.
The low pressure produced by ala 68,70 can force working media axially-movable.
In a non-limiting examples, in use, when the first blade 12 rotates, at the first blade 12 flowing underneath
Working media can clash into ala 68,70 downwards angularly.Similarly, the lower surface 74,68 of ala 68,70 can make work
Make medium to offset away from the first blade 12.This skew may cause ala 68,70 to clash into working media, and the medium that pushes the work forward
Away from the path of ala 68,70, near the upper surface 72,76 of ala 68,70, thus produce low pressure.
The low pressure produced by the ala 68,70 of degree of conclusion of the business downwards can be by the upper table of working media traction to ala 68,70
Face 72,76.Additionally, due to upper surface 72 is in the lower section of the leading edge 56,60 of the first blade profile 30, and upper surface 76 is at the second leaf
The lower section of the leading edge 58,62 of the sheet wing 32, therefore can be situated between with the second cutting pattern downward traction work by the first cutting pattern
Matter.Similarly, the downward angle of ala 68,70 and consequent move axially the cutting energy that can improve the first blade 12
Power.
If ala 68,70 is up at an angle of, then be also suitable on the contrary.Such as, when the first blade 12 rotates,
Above first blade 12, the working media of flowing can clash into ala 68,70 angled up.Similarly, ala 68,70
Upper surface 72,76 can make working media away from the path offset of ala 68,70.During making working media skew, the wing
Lobe 68,70 may clash into working media, thus produces low pressure near lower surface 74,78.Working media can be draged by these low pressure
Guide to lower surface 74,78.The top of leading edge 56,60 is can be positioned at and before lower surface 78 can be positioned at due to lower surface 74
Above edge 58,62, therefore can be by the first cutting pattern and the second cutting pattern upwards traction working media.Similarly, the wing
Lobe 68,70 can improve the cutting power of the first blade 12 to upper angle and consequent moving axially.
No matter ala 68,70 is upwardly or downwardly at an angle of, and all can increase stream by increasing the inclination of ala 68,70
Amount through the first cutting pattern with the working media of the second cutting pattern.Additionally, as it has been described above, the downward angle of the first ala 68
With to upper angle can by first cutting pattern correspondingly downwards with upwards traction working media.Therefore, with reference to the first blade
The wing 30 (it has the angle of attack of zero degree), can be controlled by the first ala 68 in the case of the angle of attack not considering the first blade profile 30
The amount of the axially flowing of working media processed and direction.
In addition to the axially flowing controlling working media, it is relative that the orientation of ala 68,70 can also control working media
Flowing radially of the axis of rotation in the first blade 12.Such as, ala 68,70 can be correspondingly lean-in relative to leading edge 56,58
Tiltedly.That is, can be by due to first blade profile 30 and the second blade profile 32 when blade profile 30,32 stretches out from body part 28
Gradual change is narrow, and therefore trailing edge 64,66 can be angled so that ala 68,70 can slope inwardly.Similarly, when the first blade 12
During rotation, can be respectively relative to the first blade profile 30 and the second blade profile 32 is radially inwardly forced away from the road of ala 68,70
The working media of footpath skew.
If it is outward-dipping that ala 68,70 is respectively relative to leading edge 56,58, then is also suitable on the contrary.Such as, if working as leaf
The sheet wing 30,32 first blade profile 30 and the second blade profile 32 little by little can broaden when body part 28 stretches out, then
Trailing edge 64,66 can be angled so that ala 68,70 can be outward-dipping.Similarly, when the first blade 12 rotates, permissible
It is respectively relative to the first blade profile 30 and the second blade profile 32 is forced away from the work of path offset of ala 68,70 radially outwardly
Make medium.
Therefore, it can axially and radially be flowed by the oriented control of ala 68,70.Additionally, when ala 68,70 becomes downwards
During angle, ala 68,70 can be also used for removing working media below the first blade 12, working media be moved out of with
After, may then pass through the first cutting pattern and the second cutting pattern action.
As it has been described above, blade assembly 10 can include the second blade 14 (Fig. 1 and Fig. 2).Is shown in Fig. 8-Figure 12
Two blades 14.Second blade 14 can be any suitable shape, size, type or structure, the most substantial parallel tetragon
Structure.Second blade 14 can include body part 82 (Fig. 8-Figure 11).Body part 82 can be any suitable shape, chi

166 orient with obtuse angle.
As explained above with described in blade assembly 10, the ala 236,238 of blade assembly 140 may be arranged as not considering
First blade profile 146 and the angle of attack of the third blade wing 150 and control cutting relative to the first cutting pattern of working media with second
Cut the axial flowing of pattern.Such as, ala 236,238 can position with any suitable angle, such as with down or up
Angle positions, in order to correspondingly increase the upper surface 156,164 of blade profile 146,150 and having accordingly of lower surface 158,166
Effect angle of heel.
Cause the increase of effective angle of heel owing to increasing ala 236,238, therefore can produce low by ala 236,238
Pressure.The low pressure produced by ala 236,238 can force working media axially-movable.
In a non-limiting examples, in use, when blade 142 rotates, in the work of blade 142 flowing underneath
Medium can clash into down angularly ala 236,238.Similarly, the lower surface 242,246 of ala 236,238 can make
Working media offsets away from blade 142.This skew may cause ala 236,238 to clash into working media, and Jie that pushes the work forward
Matter, away from the path of ala 236,238, thus produces low pressure near the upper surface 240,244 of ala 236,238.
Can be by working media traction to ala 236,238 by the low pressure that the most angularly ala 236,238 produces
