Description
BACKGROUND OF THE INVENTION
[0001] (a) Technical Field of the Invention
[0002] The present invention relates to cutter blades, and in particular
to a cutter blade of a juice extractor having a center blade with
teeth, which facilitates the cutting of the center portion of food
stuff.
[0003] (b) Description of the Prior Art
[0004] FIGS. 1 to 4 indicate conventional fruit and vegetable juice
structure comprising a press component 11, a top cover 12, a rotating
cutter blade 13, a machine body 14, a residual container 15 and
a motor 16. The juice structure cuts fruit and vegetable into small
pieces, and the press component 11 presses the food stuff together
with the rotating cutter blade 13 driven by the motor 16. The extracted
juice is filtered via the filter 132 and is collected. However,
due to the hardness/softness of the food stuff, some parts of the
fruit and vegetable may not be properly or thoroughly crushed, or
the food stuff cannot be crushed sufficiently to provide juice.
In addition, if the press component 11 is forced downward, the motor
16 could be overloaded, or the blind area D of the conventional
juice extractor is generated.
SUMMARY OF THE INVENTION
[0005] Accordingly, it is an object of the present invention to
provide a cutter blade structure of a fruit and vegetable juice
extractor comprising a press component, a top cover, a cutter blade,
a machine body, a residual container and a motor, the blade on the
cutter blade included teeth blades which are formed from a plurality
of independent teeth blade, and the teeth blades were arranged radially
to define a blade center region, characterized in that the blade
center region is provided with a plurality of center teeth blade,
and the center teeth blade is formed from a blade and the body of
the blade and the height of the blade are greater than a separate
teeth blade, thereby the crushing of the center region of the food
stuff by the blade cutter is improved.
[0006] Yet another object of the present invention is to provide
a cutter blade of a fruit and vegetable juice extractor, wherein
the directions of the blades define various blade directions into
at least two sets of teeth blade groups.
[0007] Still another object of the present invention is to provide
a cutter blade of a fruit and vegetable juice extractor, wherein
the center blade can eliminate the blind cutting area formed on
the cutter blade so that the crushing efficiently is improved.
[0008] Still yet another object of the present invention is to
provide a cutter blade of a fruit and vegetable juice extractor,
wherein the center region of the cutter blade is provided with a
plurality of center teeth blade which is divided into two groups
with opposite blade direction.
[0009] Still a further object of the present invention is to provide
a cutter blade of a fruit and vegetable juice extractor, wherein
the center teeth blade is formed as single unit from the cutter
blade. This will simplify the component of the cutter blade and
reduce the cost of blade production.
[0010] The foregoing object and summary provide only a brief introduction
to the present invention. To fully appreciate these and other objects
of the present invention as well as the invention itself, all of
which will become apparent to those skilled in the art, the following
detailed description of the invention and the claims should be read

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS
[0019] The following descriptions are of exemplary embodiments
only, and are not intended to limit the scope, applicability or
configuration of the invention in any way. Rather, the following
description provides a convenient illustration for implementing
exemplary embodiments of the invention. Various changes to the described
embodiments may be made in the function and arrangement of the elements
described without departing from the scope of the invention as set
forth in the appended claims.
[0020] Referring to FIG. 5, there is shown a fruit and vegetable
juice extractor comprising a press component 2, a top cover 3, a
cutter blade 4, a machine body 5, a residual container 6 and a motor
7. The improvement in accordance with the present is on the cutter
blade 4.
[0021] As shown in FIG. 6, the cutter blade 4 is a conic shape
with surrounding being a filter 41, and the juice of the crushed
food stuff flows through the filter 41. The upper end of the filter
is mounted to the top edge of a support component 42. The bottom
end of the filter 41 is positioned at the bottom seat 43, and the
blade 44 is positioned at the bottom seat 43 at the interior bottom
section of the filter 41.
[0022] The blade 44 is circular and is made from a metal. The top
of the blade 44 is radially arranged teeth blade 441 and the teeth
blade 441 includes a plurality of small teeth blades 442 with smaller
blade body. The shape of the small teeth blade 442 is semicircular
seat section 4421 and is tapered upward. The top section thereof
4421 is triangular protrusion. The teeth blade is extended from
the circumferential edge of the blade 44. The teeth blade 441 defines
the center region of the blade 44, which is the blind cutting region
D. In accordance with the present invention, the center region is
provided with center teeth blades 443 having a larger blade body.
The shape of the teeth blade 443 and the shape of the smaller teeth
blade 442 are the same. But the blade body of the center teeth blade
443 is larger than the smaller blade 442 by about 1.5 to 2 times.
The height of the center teeth blade 443 is higher than the teeth
blade 442 by about 1.3 to 1.7 times. The direction of the center
teeth blade 443 is divided into two groups and the direction of
the blade of the group is in opposite. As shown in FIG. 7, the center
teeth blade 443 is in a horizontal line and the direction of the
blade defines into two sets of center teeth blade 443. When the
cutter blade 4 is driven by a motor 7 to rotate, the center teeth
blade 443 possesses kinetic energy, which can crush the center portion
of the food stuff. In practical, the center teeth blade 443 can
be arranged in a cross arrangement of a star shape.
[0023] In accordance with the present invention, the center blind
cutting region of the blade 44 is provided with a plurality of separate
center teeth blade 443. The blade body and height of the center
teeth blade 443 are larger than the separate teeth blade 442. With
the mounting of the center teeth blade 443, when the cutter blade
4 rotates, the center teeth blade 443 of the center region of the
blade 44 still possesses kinetic energy. The top portion 4431 of
the center teeth blade 443 crushes the center region of the food
stuff into tiny portions, and by rotating of the cutter blade 4
to produce centrifugal force, the crushed food stuff is threw to
the residual container 6.
[0024] The height of the center teeth blade is larger than the
teeth blade 441, this will crush the center portion of the food
stuff, and further assists the crushing of food stuff by the teeth
blade 441. The installation of the center teeth blade 443 eliminates
the formation of the cutter blade. This will improve the crushing
efficiency of the fruit and vegetable juice extractor. The center
teeth blade 443 is formed from the blade 44 by punching. This will
simplify the blade module of the juice extractor and the cost of
manufacturing is lowered.
[0025] It will be understood that each of the elements described
above, or two or more together may also find a useful application
in other types of methods differing from the type described above.
[0026] While certain novel features of this invention have been
shown and described and are pointed out in the annexed claim, it
is not intended to be limited to the details above, since it will
be understood that various omissions, modifications, substitutions
and changes in the forms and details of the device illustrated and
in its operation can be made by those skilled in the art without
departing in any way from the spirit of the present invention. |
