DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT




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.




Referring to

FIG. 4

, there is shown a basic structure of a vegetable and fruit processor having a machine body


3


with one lateral side mounted with a residue container


4


. The top portion of the machine body


3


is mounted with a disc blade


5


which can be driven to rotate simultaneously by the shaft seat


31


of the machine body


3


and a top cover


6


is mounted onto the top portion of the machine body


3


. A positioning fastener


32


positioned on the machine body


3


is used to position the top cover


6


, and a feeding cylinder


61


is positioned on the top cover


6


. One side of the interior wall of the feeding cylinder


61


is an engaging body


62


, where the top and the bottom portion of the engaging body


62


are triangular shape, which allows fruit or vegetables to be inserted through an opening of the feeding cylinder


61


, and the disc blade


5


cuts and crushes the fruit and vegetables with the toothed blade


51


positioned to the disc blade


5


. The circumferential edge of the disc blade


5


is provided with a filter


52


for filtering the crushed vegetables and fruit. The filtered juice is discharged out through the guiding tube


33


and the residue is centrifuged to the other side of the residue container


4


. In accordance with the present invention, the feeding tube


7


is inserted into the feeding cylinder


61


and one lateral side of the feeding tube


7


is recessed to form an engaging slot


71


. When the feeding tube


7


is inserted into the feeding tube


61


, the engaging body


62


mounted at the feeding cylinder


61


is engaged with the engaging slot


71


. Thus, the feeding tube


7


is thus fastened without rotating within the feeding cylinder


62


. The feeding tube


7


is provided with a feeding hole


72


, and the circumferential edge of the feeding hole


72


is internally protruded out to form an engaging end


73


such that the feeding hole


72


is irregular shape with a smaller diameter, and the pushing component


8


has a rod body


82


positioned at the lower side of the end head


81


. The rod body


82


and the feeding hole


72


are of similar shape, and the external diameter of the rod body


82


is slightly smaller than the internal diameter of the feeding hole


72


and the rod body


82


can be extended to the feeding hole


72


. At the same time, the feeding hole


72


can be of different size. In other words, the feeding tube with different size of feeding hole


72


can be fabricated for vegetables or fruit of different sizes.




Referring to

FIG. 5

, in application, depending on the sizes of the vegetables and fruit


9


, an appropriate feeding hole


72


is chosen and the size is equivalent to the feeding tube


7


mounted to the feeding cylinder


61


. When a power switch is ON, the disc blade


5


rotates and the vegetables and fruit


9


are inserted into the feeding hole


72


of the feeding tube


7


. The circumferential edge of the feeding hole


72


is protruded with an engaging end


73


and the external diameter of the fruit and vegetables are equivalent to the feeding hole


72


of smaller diameter. Thus, whether strip-like fruit and vegetables or small diameter vegetables or fruit, as shown in

FIGS. 6 and 7

, the engaging end


73


restricts fruit and vegetables


9


so that they will not be driven by the bottom side of the toothed blade


51


. Accordingly, fruit and vegetables are cut and crushed to produce juice. With a number of selections for feeding tube


7


with different feeding holes


72


, the appropriate size of vegetables and juice can be used by selecting appropriate feeding tube


7


to be mounted to the feeding cylinder


61


. If the feeding tube


7


is small, the cost of production is low. The insertion of the feeding tube


7


to the feeding cylinder


61


requires an insertion and withdrawing action.




Referring to

FIGS. 8 and 9

, in order to improve the stability of mounting of the feeding tube


7


and the feeding cylinder


61


so that the feeding tube


7


will not rotate. The lateral face of the circular body


74


at the end face of the feeding tube


7


is extended with at least one protruded engaging block


75


. At the same time, the internal wall of the top side of the feeding tube


61


is provided with corresponding engaging slot


63


. When the feeding tube


7


is mounted to the feeding cylinder


61


, the fastening strength of the engaging block


75


with the engaging slot


63


is increased. The feeding tube


6


can be fastened to the feeding tube


61


and therefore the feeding tube


73


will not be rotated.




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.




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.
