Embodiment mono-:
As shown in Figure 1, be the first embodiment of the present utility model.A kind of food processor Disintegrating knife, comprise wing root 1 and two uniform wings 2 with installing hole 11, the front 22 of each wing is positioned at blade 23 1 sides and is provided with blade face 221, wing root 1 is provided with flow-disturbing breach 3 with the knife back 24 junctions of each wing, and the entirety of each wing turns to flow-disturbing breach 3 one lateral deviations.In addition, blade 23 is rectilinear edge, and the cutting edge of this blade 23 comprises linear sword 231 and is arranged on the Circular Nose Cutting Edge 232 of wing front end.
It should be noted that, the entirety of described wing turns to flow-disturbing breach one lateral deviation, refers to that installing hole center is greater than the vertical range L1 of installing hole center to knife back extended line to the vertical range L of blade extended line after Disintegrating knife moulding.In the present embodiment, the extended line of blade extended line and the knife back is positioned at the same side at installing hole center.
In the present embodiment, because the entirety of wing turns to flow-disturbing breach one lateral deviation, blade face also can be accordingly away from the center of installing hole.Therefore, in the situation that rotation pulverizing diameter is identical, the blade that is arranged on blade face edge can become longer, thereby in crushing process, the probability that blade contacts with material is larger, and the corresponding meeting of crushing effect is better.Meanwhile, blade cutting edge comprises linear sword and Circular Nose Cutting Edge, and therefore, this Disintegrating knife can be pulverized the material of different hardness, has both been not easy turnedly, and fineness that also can corresponding raising crushing material, improves the mouthfeel of drink.In addition, on Disintegrating knife, be also provided with flow-disturbing breach, in the process of pulverizing at blade High Rotation Speed, be positioned near the liquid of flow-disturbing breach, because being subject to retardance, the deceleration of flow-disturbing breach, and separate from flow-disturbing breach surface, be gathered in the vortex that forms low pressure in flow-disturbing breach near zone, and the blade that the rotating vortex in this vortex can be followed up afterwards cuts, thereby increase the probability that blade contacts with material, improved crushing material effect.Also have, in the cup of food processor, material generally rotates with the mixing material of water together with Disintegrating knife, due to the effect of centrifugal force, material is often away from the center of Disintegrating knife, the collision probability of material and Disintegrating knife is reduced, in the present embodiment, the front of wing is provided with blade face, in the process of Disintegrating knife High Rotation Speed, blade face can draw water or the effect of setting-out to liquid, liquid can constantly be rolled up and down in cup, broken the original centrifugal motion pattern of material, form turbulent motion.Therefore, strengthen the probability of material and Disintegrating knife collision, also improved accordingly the crushing effect of food processor crushing piece.It should be noted that, the mounting means difference of Disintegrating knife, to liquid take out or the mode of pressing not identical yet.If when wing is just being installed facing to bottom of cup, Disintegrating knife has the effect of setting-out to liquid, the blade face that is arranged on wing front is due to horizontal by certain angle, in the process of High Rotation Speed, blade face has changed the flow direction of current, current can move to bottom of cup along blade face direction, thereby form the effect of setting-out.If when bottom of cup is installed dorsad in wing front, contrary, Disintegrating knife can have the effect of drawing water to liquid, current can be gushed to liquid level, now generally can coordinate auxiliary disturbing flow device to carry out water conservancy diversion to current, to prevent splash phenomenon.
In the present embodiment, the bottom of flow-disturbing breach is semicircular circular arc, in order to improve the effect of flow-disturbing pulverizing, require the radius 1mm≤R≤12mm of flow-disturbing breach bottom circular arc, because, in the time that arc radius R is less than 1mm, in processes, be first difficult to processing, secondly wing is more fragile with being connected of wing root, and intensity is difficult to ensure, in crushing process, wing likely there will be the phenomenon that fractures.And in the time that arc radius is greater than 12mm, the bonding strength grow of wing and wing root, but simultaneously, the region of flow-disturbing breach can diminish, and in the process of pulverizing in rotation, the effect that forms eddy current can be poor, little to the lifting of crush efficiency.In the present embodiment, the radius of flow-disturbing breach is preferably R=3.5mm, according to realizing checking, and under this parameter, flow-disturbing crushing effect the best.
It should be noted that, in the present embodiment, blade is rectilinear edge, because when rectilinear edge processes, and more easily processing, the machining accuracy of blade cutting edge also more easily ensures.In addition, described wing can be two or more, and is not limited to two in the present embodiment.Certainly, the shape of described blade can be also curve, and is not limited to the rectilinear edge in the present embodiment.Also it should be noted that above-mentioned any conversion of the present embodiment is applicable to other embodiment of the present utility model too.

Compared with embodiment one or two leaf blade, flow-disturbing gap regions between three leaf blade wings and wing is larger, also phase strain is large for the eddy region that flow-disturbing breach near zone forms, when Disintegrating knife rotation, the scope of blade cutting eddy region is also larger, has therefore improved greatly the crush efficiency of Disintegrating knife.In addition, be positioned at the knife back 24 1 sides at the back side 25 of wing and be also provided with back of the body sword face 251.Food processor Disintegrating knife is during along A direction High Rotation Speed, the knife back 24 1 sides can form negative-pressure vacuum district, simultaneously, the liquid of Disintegrating knife surrounding is subject to the effect of external air pressure, on microcosmic, show as, fluid molecule B can be constantly filled into supplementing in this vacuum area, show as flow-disturbing or the turbulence intensity aggravation of liquid, thereby the probability of Disintegrating knife collision material increases in macroscopic view.In the back side of wing 25 knife back one sides, back of the body sword face 251 being set is exactly in order to increase this vacuum area, make the mixing material of material and water break away from centrifugal force and be subject to air pressure effect, constantly gather to Disintegrating knife center, thus the crush efficiency of lifting Disintegrating knife.It is emphasized that, when back of the body sword face is arranged to the knife back one side, while being Disintegrating knife rotation, the vacuum area forming and the eddy region of formation exist and partly overlap, thereby make liquid flow-disturbing or turbulent phenomenon more strongly, more obvious, the probability of Disintegrating knife collision material is larger, and crushing effect is more excellent.
In order to increase the negative-pressure vacuum district of the knife back one side, except the meeting of back of the body sword face is set at the back side of wing, flow-disturbing groove (as shown in Figure 5) can also be set on the knife back, or in the front of wing and/or the back side of wing be positioned at the knife back one side groove (as shown in Figure 6) be set, also can play identical effect.It should be noted that, these conversion of the present embodiment also can be applicable to other embodiment of the present utility model.
Embodiment tri-:
As shown in Fig. 7, Fig. 8, Fig. 9, be the third embodiment of the present utility model.The present embodiment and previous embodiment difference are: in the present embodiment three around wing root circumferentially uniform wing not at same plane, wing plane has certain bending angle β with respect to wing root plane, wherein, the first wing 2a and wing root plane are same plane, the second wing 2b plane is β 1 with respect to wing root plane bending angle, β 1=18 °, the 3rd wing 2c plane is β 2 with respect to wing root plane bending angle, β 2=11 °.
Meanwhile, different from previous embodiment, in the present embodiment, described flow-disturbing breach 3 bottoms are to have the taper that cone angle is α, and are chamfering transition at blade 23 with the junction C of flow-disturbing breach 3.
In the present embodiment, wing is not at same plane, therefore, in the crushing process of Disintegrating knife High Rotation Speed, near the eddy region forming flow-disturbing breach is positioned at the different plane of Disintegrating knife, this is with regard to the corresponding flow-disturbing region of having strengthened liquid in food processor cup, and different wings can be pulverized the rotating vortex of Different Plane, has promoted the crush efficiency of Disintegrating knife on complete machine.In addition, the junction of blade and flow-disturbing breach adopts chamfering transition also can reduce sharp blade while cleaning the risk of hindering hand.
It should be noted that, in the present embodiment, the bending angle of wing plane and wing root plane requires 0≤β≤20 °.Exceed after this scope according to experimental results show that, the crush efficiency of Disintegrating knife reduces on the contrary.Also it should be noted that, in the present embodiment, require 5 °≤α≤90 ° of cone angle, because be greater than after 90 ° when cone angle, flow-disturbing gap regions reduces on the contrary, and the eddy region of formation will be very limited, not obvious thereby crush efficiency promotes.On the other hand, in the time that cone angle is less than 5 °, too fragile because of the junction of wing and wing root, wing is in the middle of rotation crushing process, likely because insufficient strength occurs tearing or phenomenon of rupture.Certainly, these conversion of the present embodiment are also applicable to other embodiment of the present utility model.
