FIELD OF THE INVENTION

[0001]The present invention relates to squeezers, and particular to a squeezer for squeezing fruit to get pulp, wherein when the knife disk cover is assembled to an insertion tube of an upper cover, the gap between the knife disk cover and the horizontal press plate is very small so that the fruit is ground into pulps. When the knife disk cover is detached, the squeezer has the function of squeezing juice.

BACKGROUND OF THE INVENTION

{0002] With reference to Figs. 1 and 2, the prior art squeezer 10 is illustrated. The squeezer comprises a motor seat 1 having a motor 11; a rotary disk 2 combined to a spindle of the motor 11; a middle disk 3 combined to the motor seat 1; a knife disk 4 screwed to a central screw rod 21 of the rotary disk 2 (a knife disk seat 41 is installed below the knife disk 4); a filter mask 5 fixed to the rotary disk 2 through the knife disk 4; an upper cover 6 combined to the middle disk 3; a press tube 7 inserted into a central insertion tube 61 of the upper cover 6.

[000-3] With reference to Fig. 3, a whole cross section view of a prior art squeezer is illustrated. It is illustrated that the fruit 8 is placed into the insertion tube and then squeezed along the press tube 7 so that under the high speed grinding of the knife disk 4, the fruit 8 becomes dregs 81 rapidly to be guided into the filter mask 5 which rotates synchronously with the rotary disk 2 so as to grind the fruit into dregs 81 directed tangently into the filter mask 5 and then to be separated juice 82 from the dregs 81 through a slender net structure 51 by the centrifugation of the filter mask 5. The juice 82 flows into the middle disk 3 and then is drained out from the discharging opening 31 to a container 30. The dregs 81 are drained out from the drain groove 63 at a lateral side of the upper cover 6 to be guided into a collecting cylinder 40.

[0004]However, above mentioned prior art has no performance of getting pulp. This is because the prior art device has no improved equipment configuration for getting pulp.

DETAILED DESCRIPTION OF THE INVENTION

FIRST EMBODIMENT

[0008]Referring to Fig. 4, an exploded perspective view about the first embodiment of the present invention is illustrated. In the present invention, the pulp squeezer 20 includes a motor seat 1, a rotary disk 2, a middle disk 3, a knife disk 4, a filter mask 5A, an upper cover 6, a press tube 7, and a knife disk cover 9 which is a novel design of the present invention, an assembly view after combination see Fig. 5.

[0009]In Fig. 5, it is illustrated that a drain groove 63 extends from an outer edge of the upper cover 6. However, a pulp squeezer 20 without the drain groove 63 is still within the scope of the present invention. A stopper 3A is added to the middle disk 3 (which is described in paragraph [0017]). However, a pulp squeezer 20 without the stopper 3A is still within the scope of the present invention.

[00l0]The knife disk cover 9 is combined below an insertion tube 61 of the upper cover 6. The way for combining the knife disk cover 9 to the insertion tube 61 is not confined to the present invention. Other ways are permissible in the present invention. In Fig. 6, one combination way is illustrated, where an annular knife disk cover 9 fits over an outer edge of a bottom of the insertion tube 61 of the upper cover 6. Thereby, the knife disk cover 9 can be quickly engaged to a lower side of the insertion tube 61. Further, a horizontal press plate 92 bulges out a lower edge of the knife disk cover 9 corresponding to the knife disk 4 in an up and down reltaionship. Moreover, it is preferable that an area of the horizontal press plate 92 is equal to or larger than that of the knife disk 4 so that a very small gap 9a is retained therebetween. Next, a stop wall 93 extends downwards from a periphery of the horizontal press plate 92. A very small gap 9b is formed between the stop waIl 93 and the knife disk 4 SO that the ground fruit pulp flows downward along the gap 9b. Thereby, it is stopped by the stop wall 93 to prolong duration for grinding fruit into pulp.

[001 jun Fig. 7, it is illustrated that no stop wall (as 93 in Fig. 6) is installed on the knife disk cover 9, but a horizontal press plate 92 is used so that fruit is ground between the horizontal press plate 92 and the knife disk 4 to get pulp. Next, a bottom surface of the knife disk cover 9 is formed with a plurality of annular shallow trenches 94 which are arranged along a spiral path or a plurality of circle paths with an equal space.

Thereby, the pulp moves outwards successfully.

[0012]Referring to Fig. 8, another way for combing the knife disk cover 9 and the insertion tube 61 is illustrated. In this way, the knife disk cover 9 is installed with two exposed elastic positioning buttons 95. Positoning grooves 64 are formed along an edge of the insertion tube 61 is corresponding to the positioning buttons 95. Besides, an inner hole of the knife disk cover 9 is installed with a vertical tenon 96. A recess 65 is formed at an inner hole of the insertion tube 61, which is corresponding to the vertical tenon 96.

[0013] With reference to Fig. 9, the elastic positioning buttons 95 of the knife disk cover 9 are embedded into the positioning grooves 64 at an outer edge of the insertion tube 61 so as to combine the two. Unless using an external force, the knife disk cover 9 will not separate from the insertion tube 61. After the vertical tenon 96 is inserted into the recesses 65, the knife disk cover 9 is non-rotatable.

[0014]In the present invention, the filter mask 5A can be used instead of said filter mask 5, includes a net frame 52 and a bottom plate 53 for drain-proof (referring to Fig. 4). In other words, the slender net structure i is removed. A height of the net frame 52 can be reduced. The function of the bottom plate 53 serves to prevent the pulp or juice from flowing out of a central opening 35 of the middle disk 3. Since the filter mask 5A has no slender net structures the pulp (referring to Fig. 11) will be directly guided into the middle disk 3 by centrifugation of the filter mask 5A.

[0015]On the other hand, after detaching the knife disk cover 9 from the bottom of the insertion tube 61, the pulp squeezer 20 will be transformed to a juice squeezer for getting juice. Then the slender net structure 51 is used with the filter mask 5. By the centrifugation of the filter mask 5, the juice is separated from the dregs.

[0016]Moreover, referring to Fig. 10, in this example, the knife disk 4 is different from the prior art. A top of the knife disk 4 is installed with a plurality of teeth 42 which are arranged radially as the prior art design.

However, in the present invention, a V shape blade 43 is installed at a center thereof. An edge of the V shape blade 43 is cambered. One leg 43a of the V shape blade 43 is longer than another leg 43b thereof. The tip of the V shape blade 43 is at a center of the knife disk 4 to eliminate the central dead space in grinding. The V shape blade 43 serves to cut fibers. The V shape blade 43 is formed by one punching process.

[0017]Besides, a stopper 3A can be installed to a discharging opening of the middle disk 3 for shielding the discharging opening. There are various kinds of stoppers which are within the scope of the present invention. In Fig. 4, the discharging opening 31 of the middle disk 3 has a sliding slot 34 at an upper end thereof. The sliding slot 34 has a push key 32. A rear side of the push key 32 has a seal plate 321. A sliding plate 33 is connected below the push plate 321. A net plate 331 is at a right side of the sliding plate 33 and a stop plate 332 is at a left side thereof. When the push key 32 moves leftwards and rightwards, the sliding plate 33 will move. When the net plate 331 stops at the discharging opening 31, the juice will flow out successfully. When the stop plate 332 stops upon the discharging opening 31 (see Fig. 11), the juice 81 or pulp 83 will not flow out. When the middle disk 3 is full of pulp 83, the upper cover 6 is opened for taking out the pulp by scooping.

If the stopper 3A is not installed, the juice and pulp can flow out from the discharging opening 31.

SECOND EMBODIMENT

Referring to Fig. 12, the second embodiment of the present invention is illustrated. The structure of the upper cover 6 is illustrated. It is illustrated that a knife disk cover 62 is installed below the insertion tube 61 of the upper cover 6, which are formed integrally. The structure of the knife disk cover 61 is identical to that of the knife disk cover 9. The difference of the two is that the combining ways are different. Since the knife disk cover 62 is used in squeezing, to get juice, the conventional filter mask 5 with slender net structure is further used, which can generate a high speed centrifugation so that the fruit dregs are separated from the pulp. On the other hand, if it is desired to get pulp, the filter mask 5 is changed as the filter mask 5A without slender net structure.

THIRD EMBODIMENT

With reference to Figs. 13 and 14, the assembly view of the squeezer in the third embodiment of the present invention is illustrated. The difference of the present invention from the first embodiment is that an outer edge of the middle disk 3 has no discharging opening, while a cambered recessed groove 12 is formed on a lateral side opposite to the drain groove 63 of the motor seat 1. An outer wall of the middle disk 3 at a lower center above the cambered recessed groove 12 is installed with a button switch 3B which is formed by inserting a stud 36 into a stud hole of the middle disk 3. Refer to Fig. 14, a clip ring 38 serves to fix the stud 36. Since the stud 36 has the through hole 361 (a filter mask 362 is in the hole) corresponding to the draining hole 37 at a bottom of the middle disk 3, juice passes through the draining hole 37 and then passes out of the through hole 361 to drain out. On the other hand, when the stud 36 is rotated through 90 degrees, the through hole 31 will not communicate to the draining hole 37. Thus the juice can not drain out.
