BLADE FOR L1CUADORA FIELD OF THE INVENTION The present invention relates to a blade for use in a lighter or food processor. More specifically, the present invention relates to a blender blade having blades in the shape of wings configured to control the axial flow of a working medium provided in the blender jar. More particularly, the present invention relates to a blender blade, wherein the selective orientation of the blades can provide the axial flow directed in an upward direction and the axial flow directed in a downward direction.

BACKGROUND OF THE INVENTION Generally, a blender blade has two blade wings that extend in opposite directions of a blade body. Each of the two blade wings is equipped with cutting surfaces along their leading edges. During the operation of a blender, the blender blade rotates about an axis of rotation, and the cutting surfaces cut through the working means provided in the blender jar. Frequently, the blade wings are angled relative to the blade body to provide the blade wings with angles of attack. A variety of blade wing attack angles are used to control the axial flow of the working medium. To understand the consequences of the angulation of the blade wings in relation to the blade body, the angle of attack should be understood in relation to the aerodynamic planes. With the aerodynamic planes, the angle of attack is determined in relation to the profile line of the aerodynamic plane. The profile line is the line drawn from the leading edge to the back edge of the aerodynamic plane, and the angle of attack is the angle formed between the profile line and the horizontal line. As the angle of attack of the aerodynamic plane varies, so does the "lift" generated by the aerodynamic plane. For example, when an aerodynamic plane has a positive angle of attack, the flow medium affects the lower surface of the aerodynamic plane. Consequently, the angle of attack causes the lower surface to divert the media flow out of the aerodynamic plane. The amount of deviation is related to the orientation of the aerodynamic plane. That is, there is more deviation when there is a greater angle of attack and less deviation when there is a smaller angle of attack. Said deviation generates low pressures adjacent to the upper surface of the aerodynamic plane. For example, the lower surface pushes the flow medium away from the path of the aerodynamic plane, and therefore, an absence of the flow medium adjacent to the upper surface of the aerodynamic plane is created. Due to this absence of the flow medium, low pressures adjacent to the upper surface are provided, and these low pressures generally the aforementioned lift. As such, the larger attack angles produce low pressures adjacent to the upper surface to generate more lift, and the lower attack angles produce low pressures adjacent to the upper surface to generate less lift. The elevation generated by the angle of attack of the aforesaid aerodynamic plane can be equated with the axial flow generated by the angle of attack of a blade wing. However, unlike the aerodynamic plane mentioned above, the angle of attack of a blade wing is determined by the "turning" forward or backward of the blade wing (relative to its leading edge) along its length longitudinal. This rotation determines how much the working medium affects the upper surface or lower surface of the blade wing. Without this affectation of the work environment, the angle of attack would be zero effectively. For example, if the blade wing was angled in an upward or downward direction (but without turning forward or backward), the working means will not affect the blade wing, and the angle of attack of such a blade wing would be zero effectively. To create the necessary angle of attack, turn the blade wing forward or backward. When the blade wing is rotated forward, the working means affects the upper surface, and when the blade wing is rotated backward, the working medium affects the lower surface. The amount of rotation or rotation determines the amount of affectation, and the amount of axial flow, while the direction of rotation (forward or backward relative to its leading edge) determines the axial flow direction. For example, if the blade wing is rotated forward relative to its leading edge, the working means will affect the upper surface of the blade wing, and low pressures adjacent to the bottom surface will be generated, therefore, the working medium from top to bottom of the blender blade. On the other hand, if the blade wing is rotated backward relative to its leading edge, the working means will affect the lower surface, and the low pressure adjacent to the upper surface will be generated, therefore, the medium is directed. work from bottom to top of the blender blade. In any case, the working medium is directed through the cutting pattern of the blade wing. Since the blade wings must be rotated to generate the necessary flow of the working medium, the cutting pattern defined by the orientation of the leading edges of the blade wings is frusto-conical substantially. In fact, any rotation of the blade wing to adjust the coupling angle will create a substantially frusto-conical cutting pattern. However, ideal cutting patterns have substantially flat components. Therefore, it is necessary to control the axial flow of the working medium (for both the quantity and the direction thereof) regardless of the angle of attack of the blade wing. Said independent control will allow the cutting pattern to have a substantially flat component to create an efficient impact vector, and avoid the need to provide an angle of attack for both blade wings.

SUMMARY OF THE INVENTION Therefore, it is an object of the present invention to provide a blender blade of a configuration that provides a more efficient liquefaction of the medium to be liquefied.

DETAILED DESCRIPTION D? THE INVENTION Generally, a blender blade manufactured in accordance with one embodiment of the present invention is indicated by reference numeral 10, and is shown in Figures 1-4. The blade 10 includes a body portion 12 having an opening 13 adapted to receive a blender shaft (not shown) to which the blade 10 is fixedly engaged. The blender shaft rotates to direct the movement of the blade 10 within of a blender jar (not shown). As such, the aperture 13 and the blender shaft define the axis of rotation of the blade 10. The body portion 12 further includes an upper surface 15 and a lower surface 16. As shown in FIGS. 1-4, FIG. configures blade 10 to rotate clockwise in the blender jar. Extending from the body portion 12 is a first blade wing 21 and a second blade wing 22. The first blade wing 21 and the second blade wing 22, respectively, have upper surfaces 23, 24 and lower surfaces 25, 26. The first blade wing 21 and the second blade wing 22 are positioned asymmetrically relative to the body portion 12. For example, the first blade wing 21 shares the same horizontal plane as the body portion 12. Accordingly, the body portion 12 and the first blade wing 21 are connected uniformly, and there is a slight transition between their lower and upper surfaces. The second blade wing 22, unlike the first blade wing 21, is oriented at an acute angle relative to the horizontal plane shared by the body portion 12 and the first blade wing 21. In other words, the top surface 24 of the first blade wing 21 is obtusely oriented in relation to the body portion 12, and the bottom surface 26 is reflexively oriented with respect to the body portion 12. They extend outward from the distal ends of the first blade wing 21 and second blade wing 22, a first wing tip 31 and a second wing tip 32, respectively. The wing tips 31 and 32, respectively, include the upper surfaces 33, 34 and lower surfaces 35, 36. As seen in FIGS. 1-4, the upper surfaces 33, 34 are respectively oriented at obtuse angles with respect to the upper surfaces 23, 24. The angled relationship between the first and second flanges blade 21 and the first wing tip 31, and between the second blade wing 22 and the second wing tip 32 increases the dimensions of the cutting patterns of the blade 10. The cutting patterns of the blade are defined by the front edges 41, 42 of the first blade wing 21 and the second blade wing 22, respectively, and the first wing tip 31 and the second wing tip 32, respectively by the leading edges 43, 44. it sharpens each of these leading edges respectively beveling the first blade wing 21, second blade wing 22, first wing tip 31 and second wing tip 32. As seen in figure 2, the leading edges 41 and 43 are they form along one side of the blade 10 and share cutting responsibilities along the side of the blade. Additionally, the leading edges 42 and 44 are formed along another side of the blade 10 and share the cutting responsibilities along that side of the blade. Therefore, as the blade 10 rotates in a clockwise direction near its axis of rotation, the leading edges 41 and 43 and leading edges 42 and 44 cut through the working means provided in the blender jar. . Since the first blade wing 21 and second blade wing 22 are oriented asymmetrically with respect to the body portion 12, the blade 10 has two cutting patterns. The first cutting pattern is substantially planar, and is formed by the leading edge 41 of the first blade wing 21 and the leading edge 43 of the first wing tip 31. The second cutting pattern is frusto-conical substantially, and formed by the leading edge 42 of the first blade wing 22 and the leading edge 44 of the second wing tip 32.

As seen in Figs. 1-4, a first wing-shaped blade 51 and a second wing-shaped blade 52, respectively, extend outwardly from the rear edges 47 and 48 of the first blade wing 21 and second blade wing 22, respectively. The wing-shaped blades 51 and 52 are provided to control the axial flow of the working medium in relation to the first cutting pattern and second cutting pattern regardless of the angle of attack of the first blade flange 21 and second blade flange 22. For example, the wing-shaped blades 51 and 52 can be angled in a downward or upward direction to respectively increase the effective curvature of the upper surfaces 23, 24 and lower surfaces 25, 26. Due to the increase in effective curvature caused by the addition of the wing-shaped blades 51 and 52, low pressures are generated by the wing-shaped blades 51 and 52. The low pressures generated by the wing-shaped blades 51 and 52 force the axial movement of the working medium. The wing-shaped blades 51 and 52 include upper surfaces 53, 54 and lower surfaces 55, 56, respectively, as seen in Figures 1-4, the wing-shaped blades 51 and 52 are angled in a downward direction. That is, its lower surfaces 55, 56 are oriented at obtuse angles with respect to the lower surfaces 25, 26. As the blade 10 rotates, the working medium flowing under the blade 10 affects the leaves in the downward direction. as angled wing shapes 51 and 52. As such, the lower surfaces 55, 56 of the wing-shaped blades 51 and 52 (as seen in Figures 1-4) deflect the working medium away from the blade 10. Such deviation not only causes the wing-shaped blades 51 and 52 to strike against the working means, but also push the working means out of the path of the wing-shaped blades 51 and 52, and generates adjacent low pressures to the upper surfaces 53, 54. The low pressures generated by the wing-shaped blades angled in downward direction 51 t 52 direct the working medium to the upper surfaces 53, 54. Additionally, since the upper surface 53 is below the Bo previous rdes 41 and 43, and the upper surface 52 is below the leading edges 42 and 44, the working means is directed downwardly through the first cutting pattern and second cutting pattern. As such, the angle in the downward direction of the wing-shaped blades 51 and 52, and the axial movement caused by it, increases the cutting capacity of the blade 10. The opposite occurs if the blades are angled in an upward direction. Wing 52 and 52. For example, as the blade 10 rotates, the working medium flowing above the blade 10 in the upward direction affects the angled wing-shaped blades 51 and 52. As such, the upper surfaces 53, 54 of the wing-shaped blades 51 and 52 deflect the working medium out of the path of the wing-shaped blades 51 and 52. In the process of deflecting the working medium, the wing-shaped blades 51 and 52 they strike against the working medium, and generate low pressures adjacent to the lower surfaces 55, 56. These low pressures direct the working medium to the lower surfaces 55, 56. Since the lower surface 55 is above the leading edges 41 and 43, and the superf At the lower edge 56 above the leading edges 42 and 44, the working medium is directed upwards through the first cutting pattern and the second cutting pattern. As such, the upward angle of the wing-shaped blades 51 and 52, and the axial movement caused by it, increase the cutting ability of the blade 10. Whether the wing-shaped blades 51 and 52 are angled. in ascending or descending direction, the amount of the working medium flowing through the first cutting pattern and second cutting pattern could be increased by increasing the inclination of the wings in the form of wings 51 and 52. Additionally, as mentioned above, the ascending and descending angle of the wing-shaped leaf 51 directs the working medium in a downward and upward direction, respectively, through the first cutting pattern. Therefore, with reference to the blade wing 21 (which has an angle of attack of zero), the amount and direction of the axial flow of the working medium can be controlled by means of the wing-shaped blade 51 regardless of the angle of the blade. attack of the first blade wing 21. In addition to controlling the axial flow of the working medium, the orientation of the wing-shaped blades 51 and 52 can also control the radial flow of the working medium relative to the axis of rotation of the blade 10. For example, as seen in figures 1-4, the wing-shaped blades 51 and 52 are tilted in relation to the leading edges 41, 42, respectively. That is, since the first blade wing 21 and second blade wing 22 are gradually tapered as the blade wings 21 and 22 extend outwardly from the body portion 12, the rear edges 47 and 48 of the blade are angled. such that the wing-shaped blades 51 and 52 are tilted inwardly. As such, the working medium is deflected radially inwardly away from the trajectory of the tail-shaped blades 51 and 52. rotating the blade 10 in relation to the first blade wing 21 and second blade wing 22, respectively. The opposite occurs if the wing-shaped blades 51 and 52 are tilted out relative to the leading edges 41, 42, respectively. For example, if the first blade wing 21 and second blade wing 22 are gradually extended as the blade wings 21 and 22 extend outwardly from the body portion 12, the rear edges 47 and 48 of the blade are angled. As such, the wing-shaped blades 51 and 52 are tilted outwardly. As such, the working medium is pushed radially outwardly out of the path of the wing-shaped blades 51 and 52 as the blade rotates. blade 10 in relation to the first blade wing 21 and second blade wing 22, respectively. Therefore, the axial and radial flow can be controlled by the orientation of the wing-shaped blades 51 and 52. Additionally, when angled in the downward direction, the wing-shaped blades 51 and 52 can also be used to move the working means from below the blade 10, which after being moved, can be actuated by means of the first cutting pattern and the second cutting pattern. Generally, a blender blade manufactured in accordance with another embodiment of the present invention is indicated by reference numeral 60, and shown in Figures 5-8. The blade 60 includes a body portion 62, and an opening 63. The body portion 62 includes an upper surface 65 and a lower surface 66. Like the opening 13 of the blade 10, the opening 63 is adapted to receive a blender shaft, and the blade 60 is fixedly attached to the blender shaft. The blender shaft rotates to direct the movement of the blade 60 within a blender jar, and consequently, the opening 63 and the blender shaft define the axis of rotation of the blade 60. The blade 60 is configured to rotate in clockwise in the blender jar. Extending in the outward direction of the body portion 62, a first blade wing 71 and a second blade wing 72. The first blade wing 71 and second blade wing 72, respectively, have upper surfaces 73, 74 and surfaces lower 75, 76. The first blade wing 71 and second blade wing 72 are mirror images of each other on the opposite side of the body portion 62. In addition, the first blade wing 71 and second blade wing 72 share the same horizontal plane with the body portion 62. Accordingly, the body portion 62, first blade wing 71 and second blade wing 72 are connected uniformly, and there is a slight transition between its lower and upper surfaces. They extend outward from the distal ends of the first blade wing 71 and second blade wing 72, a first wing tip 81 and a second tip 82, respectively. The first wing tip 81 and second wing tip 82, respectively, include top surfaces 83, 84 and bottom surfaces 85, 86. As seen in Figures 5-8, the top surfaces 83, 84 are oriented at obtuse angles with with respect to the upper surfaces 73, 74. The angled relationship between the first blade wing 71 and first wing tip 81, and between the second blade wing 72 and second wing tip 82 increases the dimensions of the cutting pattern of the blade 60. The cutting patterns of the blade 60 are defined by the leading edges 91, 92 of the first blade wing 71 and second blade wing 72, respectively, and the first wing tip 81 and second wing tip 82, by the front edges 93, 94. Each of these front edges is sharpened by beveling the first blade wing 71, second blade wing 72, first wing tip 81 and second wing tip 82. As seen in Figure 6, the leading edges 91 and 93 are formed along one side of the blade 60 and share cutting responsibilities along that side of the blade. Additionally, the leading edges 92 and 94 are formed along another side of the blade 60 and share cutting responsibilities along that side of the blade. Therefore, as the blade 60 rotates in the clockwise direction near its axis of rotation, the leading edges 91 and 93 and leading edges 92 and 94 cut through the working means provided in the blender jar. . Since the first blade wing 71 and second blade wing 72 share the same horizontal plane with the body portion 62, and the leading edges 91 and 93 and leading edges 92 and 94 align to that horizontal plane, the blade 60 has a cutting pattern that is substantially flat. As seen in Figures 5-8, a first wing-shaped leaf 101 and a second wing-shaped leaf 102 extend from the blade 60 opposite the leading edges 91, 92, respectively. The wing-shaped blades 101 and 102 are provided to control the flow of the working medium relative to the cutting pattern regardless of the angle of attack of the first blade flange 71 and second blade flange 72, and can be provided in the potion of body 62, first blade wing 71 and second blade wing 72. As seen in Figures 5-8, the first wing-shaped blade 101 extends outwardly from body portion 62 adjacent rearward edge 92, and the second wing-shaped sheet 102 extends outward from the body portion 62 adjacent the trailing edge 98. The wing-shaped leaves 101 and 102 can be angled in a downward or upward direction (depending on their relative position) to increase the effective curvature of the upper surface 65, lower surface 66, upper surfaces 73, 74 and lower surfaces 75, 76. Due to the increase in the effective curvature caused by the addition of wing flaps 101 and 102, low pressures are generated by the wing-shaped blades 101 and 102. The low pressures generated by the wing-shaped blades 101 and 102 force the axial movement of the working medium. Generally, the hook-shaped wings 101 and 102 are shown, and include the first curved surfaces 103, 104 and second curved surfaces 105, 106, respectively. As seen in FIGS. 5-8, the wing-shaped blades 101 and 102 are angled in a downward direction. As such, a majority of second curved surfaces 105, 106 in relation to the lower surface 66 and surfaces are obtusely oriented. lower 75, 76. As the blade rotates 60, the working medium flowing under the blade 60 deflects in the downward direction the angled wing-shaped blades 101 and 102. In fact, the second curved surfaces 105, 106 deflect the working medium away from the blade 60, and at diverting the work medium, in effect hits large particles provided in the work environment. Such deflection also pushes the working medium out of the path of the wing-shaped blades 101 and 102, therefore, low pressures adjacent the first curved surfaces 103, 104 are generated. These low pressures direct the working medium to the first curved surfaces 103, 104 in relation to the cutting pattern, the working medium is directed in a downward direction axially through the first cutting pattern. Therefore, the axial movement caused by the wing-shaped blades 101, 102 increases the cutting ability of the blade 60. The opposite occurs if the blades 101 and 102 are angled upwards. the blade 60 rotates, the working medium flowing above the blade 60 deflects in the upward direction the angled wing-shaped blades 101 and 102. In fact, the first curved surfaces 103, 104 deflect the working medium away from the blade 60, and by diverting the work medium, in effect hits large particles provided in the work environment. Such deflection also pushes the working medium out of the path of the wing-shaped blades 101 and 102, therefore, low pressures adjacent the second curved surfaces 105, 106 are generated. These low pressures direct the working medium to the second curved surfaces 105, 106, and due to the vertical position of the second curved surfaces 105, 106, relative to the cutting pattern, the working medium is directed axially upwardly through the first cutting pattern. Therefore, the first axial movement caused by the wing-shaped leaves 101, 102, increase the cutting capacity of the blade 60. Either the wing-shaped blades 101 and 102 are angled in an upward or downward direction, the larger particles in the working medium are sprayed. The first curved surfaces 103, 104 and second curved surfaces 105, 106 (depending on the orientation of the wing-shaped blades 101) will break apart these large particles, and allow the remaining particles to make contact with the leading edges 91 and 93 and front edges 92 and 94. However, when angled in a downward direction, the wing-shaped blades 101 and 102 may also be used to move the working means from under the blade 60. After it has been moved, the blade may be actuated. working medium by means of the cutting pattern of the blade 60. Additionally, although the first blade wing 71 and second blade wing 72 have zero-degree attack angles, the amount and direction of the axial flow of the working medium can be controlled. by means of the wing-shaped blades 101 and 102 independently of the angle of attack of the first blade flange 71 and second blade flange 72. In addition to controlling the axial flow of the working medium, the orientation of the wing-shaped blades 101 and 102 can also control the radial flow of the working medium in relation to the axis of rotation of the blade 60. For example, if the first blade is tilted in the form of a wing 101 and a second wing-shaped leaf 102 inwardly or outwardly relative to the leading edges 91, 92, the radial flow of the working medium could selectively be directed. When the wing-like blades 101 and 102 are inclined inward relative to the leading edges 91, 92, respectively, the working means affects the wing-shaped blades 101 and 102, and is directed inwardly. When the wing-shaped blades 101 and 102 are inclined outwardly relative to the leading edges 91, 92, respectively, the working means affects the wing-shaped blades 101 and 102, and is directed outwards. Therefore, both flows, radial and axial, of the working medium can be controlled by the orientation of the wings 101 and 102. Generally, a blender blade manufactured in accordance with another embodiment of the present invention is indicated by the numerical reference 110, and is shown in figures 9-12. The blade 110 includes a body portion 112, and an opening 113 provided in the body portion 112 that are adapted to receive a blender shaft. The body portion 112 further includes an upper surface 115 and a lower surface 116. The blade 110 is fixedly attached to the blender shaft, and the rotation of the blender shaft directs the movement of the blade 110 into a blender jar. Accordingly, the opening 113 and blender shaft define the axis of rotation of the blade 110. The blade 110 is configured to rotate clockwise in the blender jar, and extends outwardly from the portion of the blender. body 112 a first blade wing 121 and a second blade wing 122. The first blade wing 121 and second blade wing 122, respectively, have upper surfaces 123, 124 and lower surfaces 125, 126. As seen in the figures 9-12, the first blade wing 121 and second blade wing 122 are positioned asymmetrically relative to the body portion 112. For example, the first blade wing 121 shares the same horizontal plane as the body portion 112. In FIG. Consequently, the body portion 112 and the first blade wing 121 are connected uniformly, and thereby, a slight transition is created between their upper and lower surfaces. However, the second blade wing 122, unlike the first blade wing 121, is oriented at an acute angle with respect to the horizontal plane shared by the body portion 112 and first blade wing 121. As such., the upper surface 124 of the second blade wing 121 is obtusely oriented with respect to the body portion 112, and a lower surface 126 is oriented reflectively with respect to the body portion 112. Since the first wing of blade 121 and second blade wing 122 do not include wing tips, cutting patterns of blade 110 are defined by the leading edges 131, 132 of the first blade wing 121 and second blade wing 122, respectively. The leading edges 131, 132 are formed by beveling the first blade wing 121 and second blade wing 122, respectively. As seen in Figure 10, the leading edge 131 is adapted to handle the cutting responsibility on one side of the blade 110, and the leading edge 132 is adapted to handle the cutting responsibility on the other side of the blade 110. Accordingly, as the blade 110 rotates clockwise about its axis of rotation the leading edge 131 of the first blade wing 121 and leading edge 132 of the second blade wing 122 cut through the middle of work. However, since the first blade wing 121 and second blade wing 122 are oriented asymmetrically with respect to the body portion 112, the blade 110 has two cutting patterns. The first cutting pattern is substantially planar, and is formed by the leading edge 131 of the first blade wing 121. The second cutting pattern is frusto-conical substantially, and is formed by the leading edge 132 of the second blade wing 122. As seen in Figures 9-12, a first wing-shaped blade 141 and a second wing-shaped blade 142, respectively, extend outwardly from the first blade wing 121 and second blade wing 122.

The wing-shaped blades 141 and 142 are angled relative to the first blade 121 and second blade blade 122 along the curved lines 133 and 134, respectively. The wing-shaped blades 141 and 142 are provided to control the flow of the working medium in relation to the first cutting pattern and second cutting pattern regardless of the angle of attack of the first blade flange 121 and second blade flange 122. For example, the wing-shaped blades 141 and 142 may be angled in an upward or downward direction to respectively increase the effective curvature of the upper surfaces 123, 124 and lower surfaces 125, 126. However, due to the increase in effective curvature caused by the addition of the wing-shaped blades 141 and 142, low pressures are generated by the wing-shaped blades 141 and 142, and these low pressures force the axial movement of the working medium. For example, the wing-shaped blades 141 and 142, respectively, include the upper surfaces 143, 144 and lower surfaces 145, 146. The wing-shaped blades 141 and 142, shown in Figures 9-12, are angled at descending direction, and the lower surfaces 145, 146 are oriented at obtuse angles with respect to the lower surfaces 125, 126. Therefore, as the blade 110 rotates, the working medium flows under the blade 110 affects in the direction descending the angled wing-shaped blades 141 and 142. As such, the lower surfaces 145, 146 of the wing-shaped blades 141 and 142 (as seen in figures 9-12) deflect the working medium away from the blade 110. Such deflection not only causes the wing-shaped blades 141 and 142 to strike against the working means, but also push the working means out of the path of the blades in the form of flanges 141 and 142, and generate low pressures adjacent to the upper surfaces 143, 144. The low pressures generated by the angled wing-shaped blades 141 and 142 downwards direct the working means to the upper surfaces 143, 144. Additionally, since the upper surface 143 is below the edge Above 131, the upper surface 144 is located below the leading edge 132, the working medium is directed downwards through the first cutting pattern and the second cutting pattern. As such, the angle in the downward direction of the wing-shaped blades 141 and 142, and the axial movement caused by it increases the cutting ability of the blade 110. The opposite occurs if the blades are angled upwardly in the shape of the blade. Wing 141 and 142. For example, as the blade 110 rotates, the working means flowing above the blade 110 will affect the angled wing-shaped blades 141 and 142 in an upward direction. As tai, the upper surfaces 143, 144 of the wing-shaped blades 141 and 142 deflect the working medium away from the path of the wing-shaped blades 141 and 142. During this process of deflection of the working medium, the wing-shaped blades 141 and 142 they strike against the working medium, and generate low pressures adjacent the lower surfaces 145, 146. These low pressures direct the working medium towards the lower surfaces 145, 146. Since the lower surface 145 is above the bores. In the above directions 131, and the bottom surface 146 is located above the leading edge 132, the working means is directed upwardly through the first cutting pattern and second cutting pattern. As such, the upward angle of the wing-shaped blades 141 and 142, and the axial movement caused by it increases the cutting ability of the blade 110. Either the wing-shaped blades 141 and 142 are angled. in ascending or descending direction, the amount of the working medium flowing through the first cutting pattern and the second cutting pattern could be increased by increasing the inclinations of the wing-shaped blades 141 and 142. Additionally, as mentioned above, the upward and downward angles of the wing-shaped blades 141 and 142 direct the working medium in ascending and descending directions, respectively. Therefore, with reference to the blade wing 121 (having an angle of attack of zero), the amount and direction of the axial flow of the working medium can be controlled by means of the wing-shaped blade. 141 independently of the angle of attack of the first blade wing 121. In addition to controlling the axial flow of the working medium, the orientation of the wing-shaped blades 141 and 142 can also control the radial flow of the working medium in relation to the axis of rotation of the blade 110. For example, as shown in Figures 9-12, the wing-shaped blades 141 and 142 are inclined inwardly. in relation to the leading edges 131, 132, respectively. That is, since the first blade wing 121 and second blade wing 122 are gradually tapered as the blade wings 121 and 122 extend outwardly from the body portion 112, the curved lines 133 and 134 of the blade are angled. such that the wing-like blades 141 and 142 are tilted inwardly. As such, the working medium biased out of the path of the wing-like blades 141 and 142 as the blade 110 rotates, is pushed inward relative to the first blade wing 121 and second blade wing 122, respectively. The opposite occurs if the wing-like blades 141 and 142 are tilted out relative to the leading edges 131, 132, respectively. For example, if the first blade wing 121 and second blade wing 122 are gradually expanded as the blade wings 121 and 122 extend outwardly from the body portion 112, the curved lines 133 and 134 are angled. way they tip out the wing-shaped leaves 141 and 142. As such, the working medium deviated outwardly from the trajectory of the wing-shaped blades 141 and 142 as the blade 110 rotates, it is pushed outward relative to the first blade wing 121 and second blade wing 122, respectively. Therefore, both flows, radial and axial, of the working medium can be controlled by means of the orientation of the wing-shaped blades 141 and 142. Additionally, when angled in the downward direction, blades in the form of wing 141 and 142 for moving the working means from below the blade 110, and such working means, after moving, can be actuated by means of the first cutting pattern and second cutting pattern.

Therefore, to clarify the foregoing, it should be evident that a blender blade manufactured as described in the present invention substantially improves the technique and further achieves the objectives of the present invention.
