ABSTRACT:
BACKGROUND OF THE INVENTION
(a) Technical Field of the Invention
The present invention relates to a fruit and vegetable processor, and in particular, to an improved structure of a fruit and vegetable processor which can process or crush fruit or vegetables, and which has a smaller external diameter for vegetables in strips.
(b) Description of the Prior Art
Nowadays, it is very common that fruit and vegetables are crushed into juice for drinking. In view of various types of vegetables and fruit, those with a hard texture require longer processing time or a larger crushing force in order to extract juice from the fruit and vegetable.
FIG. 1
is an exploded perspective view of a conventional fruit and vegetable processor
1
comprising a pushing element
11
, a top cover
12
, a disc blade
13
, a machine body
14
and a residue container
15
. The pushing element
11
is a cylindrical body having a larger end head, and having a long slot
111
at one side. The lower side end of the long slot
111
has a conic-shaped opening and the top cover
12
is a circular base body
121
having a feeding cylinder
122
. The internal diameter of the feeding cylinder
122
is equivalent to that of the cylinder body of the pushing element
11
. The inner wall of the feeding cylinder
122
is an engaging body
123
having a protruded bottom end. The engaging body
123
is corresponding to the long slot
11
of the pushing element
11
so that the pushing element
11
is extended into the feeding cylinder
122
, the engaging body
123
is engaged at the long slot
11
and the pushing element
11
will not rotate. One side of the base body
121
is extended to form a side cover
124
, and the two corresponding sides of the base body
121
are provided with a positioning plate
125
. The positioning plate
125
is provided with a depressed engaging slot
126
. Further, the disc blade
13
is a conic disc body and the bottom side face is provided with a flat blade
131
. The circumferential edge of the flat blade
131
is provided with a plurality of toothed blade
132
, and the circumferential edge is a filter
133
.
In addition, the machine body
14
has a base seat
141
having a motor (not shown) within the interior of the base seat
141
. The top portion of the base seat
141
is a holding seat
142
having a shaft seat
143
at the center driven by the motor. One side of the holding seat
142
has a residue outlet
144
and the other side is provided with a guiding tube
145
. At the same time, the center of the base seat
141
is pivotally mounted with a positioning fastener
146
which can swing freely. A residue container
15
is engaged at the side of the residue outlet
144
of the machine body
14
.
In combination, the disc blade
13
is engaged at the shaft seat
143
of the machine body
14
for positioning. The top cover
12
is mounted on the holding seat
142
of the machine body
14
and the positioning fastener
146
is rotated upward so that the fastener is positioned at the engaging hole
126
of the positioning plate
125
, and the top cover
12
is then positioned. In application, as shown in
FIGS. 2 and 3
, the motor is switched on to operate and the shaft seat
143
drives the disc blade
13
to rotate simultaneously. Next, if vegetables and fruit
2
are placed into the feeding cylinder
122
, and the pushing component
11
is inserted to press the vegetables and fruit
2
, so that the fruit and vegetables will not move freely and the toothed blade
132
at the base of the disc blade
13
to crush the vegetable and fruit
2
into juice, and the filter
132
is used for filtering the juice, so that the purified juice flows down from the guiding tube
145
. The bottom of the guiding tube
145
is a container to collect the juice and the residue is thrown to the residing container
15
.
The drawbacks of the conventional device are that small sized vegetables and fruit cannot be positioned by the pushing component
11
which affect the efficiency of crushing. If a larger top cover
12
is required, a larger machine has to be used and therefore, the cost of production is increased. Accordingly, it is an object of the present invention to provide a fruit and vegetable processor, which mitigates the above drawbacks.
SUMMARY OF THE INVENTION
It is an object of the present invention to provide a vegetable and fruit processor, wherein the feeding cylinder above the top cover has a feeding tube, and the feeding tube has a smaller hole diameter and the middle of one side is protruded so that smaller sized vegetables or fruit strips are placed in the processor, it provides a positioning effect so that the vegetable and fruit in strips will not rotate simultaneously with the blade in the course of cutting.
Yet another object of the present invention is to provide a fruit and vegetable processor, wherein bottom side of the circular body of the side end of the feeding tube is extended to form an engaging block and the internal wall of the upper side end of the feeding cylinder is provided with a corresponding engaging slot.
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 in conjunction with the accompanying drawings. Throughout the specification and drawings identical reference numerals refer to identical or similar parts.
Many other advantages and features of the present invention will become manifest to those versed in the art upon making reference to the detailed description and the accompanying sheets of drawings in which a preferred structural embodiment incorporating the principles of the present invention is shown by way of illustrative example.
