Description

Mixing blade

This creation is related to the blade of a food processor or blender, especially a two-blade agitator blade.

Typically, a straight agitating blade has two blades that extend outwardly from the body and from the body. Both blades have sharp leading edges. The agitating blade operates with the agitation assembly to cut and agitate the agitated medium in the agitating cup.

The angle of formation of the two blades is positively related to the stirring efficiency of the stirring blade to the agitated medium, that is, the agitating blade in operation, and the angle of formation of the two blades directly affects the flow direction of the agitated medium.

At present, the straight agitating blade extends outwardly from the main body and can be divided into two horizontal blades, two inclined blades or a horizontal blade with a tilting blade. The two horizontal blades mean two blades which are substantially at the same level as the surface of the main body. In this way, the medium to be stirred usually does not have good pressing and pulling force, and therefore, the stirred medium cannot be efficiently Near the center of the agitator shaft assembly and pulled down and outward.

The two inclined blades can be roughly divided into the same direction, for example, upward or downward, or inclined in different directions, for example, one blade is upward and the other blade is downward. Regardless of the tilting direction, the two inclined blades generally form two parallel bending lines on the main body, so that the agitated medium cannot be efficiently stirred during the stirring process, that is, the agitated medium cannot efficiently approach the stirring shaft. The central position of the shaft assembly is pulled downwards and outwards.

Furthermore, the horizontal blade with the inclined blade does not efficiently allow the agitated medium to enter from the central position of the agitator shaft assembly and is pulled downward and outward, so that this method does not produce efficient agitation and Cutting results.

Therefore, any form of straight mixing blade is currently not efficient enough to be stirred. The medium is pulled down from the center of the stirring blade, and then the stirring medium is pulled from the lower side of the stirring blade to the outside, and flows along the periphery of the stirring blade, and then flows into the center of the stirring blade, in other words, the stirring blade cannot be efficiently cut at present. And stir the stirred medium.

In view of the above-mentioned deficiencies, the purpose of the present invention is to provide a stirring blade which can efficiently cut and stir the agitated medium, and forms a force pulling downward toward the center of the agitated medium above the stirring blade during the stirring process, and The agitated medium below the agitating blade forms a force that pulls out to the outside.

In order to achieve the above object, the stirring blade of the present invention is used to stir and cut the stirred medium in the mixing cup. The agitating blade includes a main body, an upper inclined blade, and a lower inclined blade. The body has mounting holes and defines a symmetry axis along the surface plane of the body and across the mounting holes. The axis of symmetry divides the mounting aperture into two generally symmetrical patterns. The upper oblique blade extends outward from the main body and forms a slow lifting section and a steep rising section, and the slow lifting section is between the main body and the steep rising section of the upper inclined blade. The lower oblique blade extends outward from the body and is located on the opposite side of the upper oblique blade and forms a descending section and a steeply rising section. The descending section is between the main body and the steep section of the lower slanting blade. There is a first bending line between the rising section of the upper inclined blade and the main body. There is a second bending line between the descending section of the lower inclined blade and the main body. The axis of symmetry is between the first bending line and the second bending line. The axis of symmetry and the first bend line define a first polygonal pattern on the surface of the body. The axis of symmetry and the second bend line define a second polygonal pattern on the surface of the body. The first polygonal pattern and the second polygonal pattern are asymmetrical.

In this way, since the first polygonal pattern and the second polygonal pattern formed by the first bending line and the second bending line are asymmetrical, the upper inclined blade and the lower inclined blade can efficiently improve the stirring and cutting. Efficiency, while the agitated material flows along an efficient agitation path.

The detailed construction, features, assembly or use of the agitating blades provided by this creation will be described in the detailed description of the subsequent embodiments. However, those of ordinary skill in the art should understand that the detailed description and specific embodiments of the present invention are merely used to illustrate the present invention and are not intended to limit the scope of the patent application.

The stirring blade 30 of the present invention is used for connection with the agitating assembly 10, and the agitating assembly 10 has a drive shaft 11, two washers 13, and a nut 15. The two spacers 13 are respectively connected to the top surface 311 and the bottom surface 313 of the main body 31 of the stirring blade 30. The two spacers 13 respectively have a through hole 131. The through hole 131 communicates with the mounting hole 315 of the main body 31 of the stirring blade 30, and the mounting hole 315 penetrates through the main body 31. Top surface 311 and bottom surface 313. The drive shaft 11 passes through the hole 131 of the two washers 13 and the mounting hole 315 of the main body 31, and is matched with the through hole 131 and the mounting hole 315, and is fixedly coupled to the drive shaft 11 through the nut 15, so that the stirring blade 30 is fixed to the stirring. On component 10. The drive shaft assembly 10 is fixed to a stirring cup (not shown), and the stirring blade 30 is driven as the drive shaft 11 rotates to agitate and cut the stirred medium in the stirring cup. The medium to be stirred is, for example, various fruits, ice cubes, flour, beans, and miscellaneous grains.

As shown in Fig. 2, this figure is a perspective view of the stirring blade 30 of the present invention. The top surface 311 and the bottom surface 313 of the body 31 of the agitating blade 30 are substantially planar. In other embodiments, the top surface 311 and the bottom surface 313 may be non-planar geometries, such as curved surfaces. The top view of the mounting hole 315 is generally rectangular, but in other embodiments, the top view of the mounting hole 315 may be other geometric shapes such as circular, semi-circular, and the like.

The upper oblique blade 33 and the lower oblique blade 35 of the agitating blade 30 extend from the main body 31, respectively, and the lower oblique blade 35 is located on the opposite side of the upper oblique blade 33. The upper oblique blade 33 extends upward and outward from the body 31 and has a sharp leading edge 331 and an opposite trailing edge 333. The lower oblique blade 35 is downward from the main body 31 And extending outward, and has a sharp leading edge 351 and an opposite trailing edge 353. The leading edges 331, 351 of the blades 33, 35 are the leading edges during the rotation of the agitating blade 30. Therefore, the leading edges 331, 351 and the trailing edges 333, 353 of the blades 33, 35 are along with the agitating blades. 30 is rotated to change direction, and is not limited to the embodiment.

The upper slanting blade 33 forms a gentle section 335 and a steep section 337 which is located between the main body 31 and the steep section 337. The lower inclined blade 35 forms a descending section 355 and a steeply rising section 357, and the descending section 355 is located between the main body 31 and the steep rising section 357. It is indicated that the upper oblique blade 33 and the lower oblique blade 35 respectively have two different degrees of inclination. In other embodiments, the blades 33 and 35 may have more or less inclined degrees. The blades 33, 35 are not limited to two different degrees of inclination.

As shown in Fig. 3, this figure is a schematic plan view of Fig. 2. Along the surface 311 of the body 31 and over the mounting aperture 315 defines an axis of symmetry 317 that extends opposite side edges of the body 31. The axis of symmetry 317 divides the mounting aperture 315 into two generally symmetrical patterns. In fact, the axis of symmetry 317 does not necessarily appear on the surface 311, but may be defined from the surface 311. In other embodiments, the opposite side edges of the body 31 may also be flat lines, arcs, or other geometric lines.

There is a first bending line 37 between the upper oblique blade 33 and the main body 31. There is a second bending line 39 between the lower inclined blade 35 and the main body 31. The first bending line 37 and the second bending line 39 respectively define a starting position at which the upper oblique blade 33 and the lower oblique blade 35 are bent. The first bending line 37 and the second bending line 39 are substantially two lines that are not parallel. The axis of symmetry 317 is between the first bending line 37 and the second bending line 39. The axis of symmetry 317 and the first bending line 37 define a first polygonal pattern 371 on the top surface 311 of the body 31. The first polygonal pattern 371 is roughly quadrangular. The axis of symmetry 317 and the second bend line 39 define a second polygonal pattern 391 at the top surface 311 of the body 31, the second polygonal pattern 391 being substantially quadrangular. The first polygonal pattern 371 and the second polygonal pattern 391 are asymmetrical. The front end 373 of the first bend line 37 is closer to the axis of symmetry 317 than its rear end 375. The rear end 395 of the second bend line 39 is closer to the axis of symmetry 317 than its front end 393.

The top surface 311 of the main body 31 has a substantially hexagonal appearance, and the first bending line 37 and the second bending line 39 are respectively two opposite sides 37, 39 of a hexagon. In other embodiments, the sides of the polygonal pattern may include straight lines, arcs, wavy lines, or any geometric line. However, regardless of the change in the surface shape of the main body 31, the first bending line 37 and the second bending line 39 are the main body 31. The opposite sides 37, 39 of the top surface 311.

Because the upper slanting blade 33 is bent upward along the first bending line 37, the lower slanting blade 35 is bent downward along the second bending line 39. Therefore, the upper slanting blade 33 and the lower slanting blade 35 are A downwardly inclined structure inclined from the leading edges 331, 351 to the trailing edges 333, 353, respectively, is formed, and the downwardly inclined structure can efficiently pull down the agitated medium to increase the chance of the agitated medium being cut and stirred.

As shown in FIGS. 4 to 6, the fourth to sixth figures are respectively a front view, a rear view, and a bottom view of FIG. 2. The upper oblique blade 33 and the lower oblique blade 35 also have guiding slopes 3311, 3511, respectively. The guiding ramps 3311, 3511 are rearward and downward from the sharp leading edges 331, 351 of the upper oblique blade 33 and the lower oblique blade 35, respectively. There is a non-sharp section 3313 (or a blunt section) between the sharp leading edge 331 of the upper oblique blade 33 and the first bending line 37.

In this embodiment, the guiding slopes 3311, 3511 are smooth planes. In other embodiments, the guiding ramps 3311, 3511 can be arcuate, multi-segmented curved surfaces, multi-segment planes, or other geometric shapes, or a mixture of multiple geometries. Similarly, the sharp leading edges 331, 351 may also be a combination of smooth straight lines, arcs, semi-circular lines, or blends, and are not limited to straight lines.

When the agitating blade is rotated counterclockwise, the rotating upper oblique blade forms an inverted cone-shaped agitation pattern above the main body, and the rotating lower oblique blade forms a standing conical stirring pattern under the main body. The standing conical stirring pattern cuts and agitates the agitated medium below the main body, and moves the agitated medium from the sharp leading edge to the trailing edge. Because the lower oblique blade is inclined outward and downward, the agitated medium It is pulled downward from the middle of the main body and is squeezed to flow under the lower slanting blade and moves along the descending section to the steeply rising section of the lower slanting blade, and then from the periphery of the steeply rising section of the lower slanting blade Moving upwards, at this time, a substantially blank area will be formed behind the lower slanting blade to increase the flow of the agitated medium. Then, the inverted cone stirring pattern agitates and cuts the moving agitated medium, and the periphery of the steeply rising section of the upper oblique blade will again squeeze and push the stirred medium to flow upward, so that the stirred medium will flow upward to After the higher position, it flows back down to the main body, that is, the middle position, and then the sharp leading edge of the rising section of the upper inclined blade again cuts and stirs the stirred medium, and the guiding inclined surface of the upper inclined blade guides The agitated medium is pulled down into the center of the standing cone stirring pattern.

In short, the upper and lower slanting blades of the agitating blade are respectively in the shape of a rotating shaft The stirring pattern is inverted and standing, and the agitated medium that is cut and stirred forms an approximately elliptical reflow pattern along the outer circumference of the stirring blade. In this way, the stirred medium is repeatedly inserted from the center of the standing tapered stirring pattern and the inverted tapered stirring pattern and pulled downward and outward to improve the working efficiency of stirring and cutting.

In other words, the agitated blade is moved up and down along the circumference of the agitating blade by the agitating blade of the present invention, and is returned to the middle of the agitating blade to form an efficient agitation procedure.

Finally, it is emphasized that the constituent elements disclosed in the foregoing embodiments are merely illustrative and are not intended to limit the scope of the present invention. The substitution or variation of other equivalent elements should also be covered by the scope of the patent application of the present application. .
