Description

Technical Field

[0001] The utility model relates to the technical field of juicers, in particular to a cutting knife and a juice extractor with the same. Background Art

[0002] The juice extractor is developed on the basis of the conventional juicer. Its main working purpose is to turn fruits into juice to improve the taste and facilitate drinking. For the low-speed screw extrusion technology of the juice extractor, the lower the extrusion speed, the better. Generally, the juice extractor rotates about 75 revolutions per minute, and slowly squeezes out the juice like squeezing a towel, without destroying the fruit cell structure, and the fruit nutrition is preserved. Moreover, the low-speed juice extraction does not generate high heat, and also avoids the problem of juice being oxidized by heat.

[0003] When the juice extractor is juicing, it is necessary to first cut some large raw materials (such as carrots) into small pieces so that the large raw materials can also enter the juice outlet mechanism. The existing cutting tools have the following problems. First, the cutting effect is average, and the cut pieces are relatively large in volume, resulting in the raw materials getting stuck at the outlet and unable to enter the juice outlet mechanism. Second, there is no function of pushing the material, and the cut raw materials can only be rotated passively under the driving force of the rotation of the tool, which may cause some raw materials to remain at the bottom of the material barrel and unable to enter the juice outlet mechanism.

[0004] Chinese Patent No. CN112971509A discloses a stirring knife of a juice extractor, which includes a base located at the central part and three blades radially arranged in the circumferential direction of the base: a first blade, a second blade and a third blade. The bottom of the base includes a connecting mechanism, which can be connected to the power mechanism of the juice extractor and rotates under the drive of the power mechanism. The stirring knife of the juice extractor of the present invention realizes a better cutting effect and can more efficiently push the raw materials into the juice outlet mechanism by reasonably setting parameters such as the lengths, angles and positions of the three blades, thereby improving the juice extraction efficiency. The present invention also discloses a juice extractor.

[0005] However, this stirring knife has certain limitations. If the pulp is located above the blade of the stirrer and does not contact the blade edge, the blade edge cannot cut it, thus reducing the juicing effect. Summary of the Utility Model

[0006] In order to solve the above problems existing in the prior art, the utility model provides a cutting knife and a juice extractor with the same.

[0007] The above problems of the utility model are solved by the following technical solutions:

[0008] A cutting knife includes a rotating part connected to a knife seat and a blade extending outward from the rotating part, and a blade edge is provided on the side part of the blade along the rotating direction;

[0009] The blade at least includes a first knife, and a first stop rib extends upward from the first knife for colliding and stopping the pulp.

[0010] The further setting of the above technical solution is: It further includes a second knife, and the end of the second knife extends upward and is higher than the end of the first knife in position.

[0011] The further setting of the above technical solution is: A second stop rib extends downward on the lower end surface of the second knife.

[0012] The further setting of the above technical solution is: The first knife is arranged in an arc shape; the second knife is arranged in a spiral shape.

[0013] The further setting of the above technical solution is: Both the first knife and the second knife are provided with two cutting edges.

[0031] To further elaborate on the technical means and effects adopted by the present invention to achieve the predetermined utility model purpose, the following, in conjunction with the attached drawings and preferred embodiments, details the specific embodiments, structures, features and their effects according to the present invention as follows.

[0032] As Figures 1-5 shown, the following embodiments disclose a cutting knife and a juice extractor having the same.

[0033] Embodiment 1

[0034] This embodiment discloses a cutting knife 100, which includes a rotating part 110 connected to a knife seat 500 and a blade extending outward from the rotating part 110, and a blade edge 101 is provided on the side of the blade along the rotating direction;

[0035] The blade at least includes a first knife 120, and a first retaining rib 121 extends upward from the first knife 120 for collision stopping of the pulp.

[0036] The above is the basic solution of this embodiment.

[0037] Specifically referring to Figure 1 shown, the first knife 120 and the rotating part 110 are integrally formed, the first knife 120 extends outward from the rotating part 110, and when the rotating part 110 rotates under the action of the knife seat 500, the first knife 120 rotates around the axis of the rotating part 110 together to cut the pulp and extract juice.

[0038] Since the cutting knife 100 is usually arranged at the bottom of the juice extraction cavity a, larger pieces of pulp will fall above the cutting knife 100 and cannot contact the cutting edge 101 on the cutting knife 100, so cutting cannot be performed. Therefore, in this embodiment, a first retaining rib 121 is arranged on the first knife 120. The first retaining rib 121 extends upward from the upper end surface of the first knife 120 to stop the pulp that falls above the first knife 120. During the stopping process, due to the rotation of the first knife 120, the pulp falls to the side of the first knife 120 and is cut when the first knife 120 rotates to this position again.

[0039] Preferably, in this embodiment, a plurality of first retaining ribs 121 can be arranged.

[0040] In this embodiment, another structure of the cutting knife 100 is also provided. The specific implementation manner is as follows: It further includes a second knife 130. The end of the second knife 130 extends upward and is higher than the end of the first knife 120.

[0041] In this embodiment, referring to Figure 2 As shown, in order to increase the cutting efficiency of the cutting knife 100 for the pulp, a second knife 130 is provided, and the position of the second knife 130 is relatively high, which is convenient for cutting larger pieces of pulp.

[0042] Similar to the structure of the first knife 120, a second retaining rib 131 extends downward on the lower end surface of the second knife 130.

[0043] In this embodiment, the function of the second retaining rib 131 is not only to stop the pulp so that it can fall to a position where it can contact the cutting edge 101 of the second knife 130, but also to support the second knife 130. The end position of the second knife 130 is relatively high. When a large fruit plate is placed on the cutting knife 100, for a blade with a relatively small thickness, the blade will be bent and the outer end of the blade will be deformed. Therefore, setting the second retaining rib 131 can play a certain supporting role for the blade.

[0044] In this embodiment, the first knife 120 is arranged in an arc shape; the second knife 130 is arranged in a spiral shape.

[0045] The first knife 120 is close to the bottom of the juice extraction cavity a and is used for cutting the pulp at the bottom. Therefore, an arc structure is set to increase the length of the cutting edge 101 as much as possible, so as to quickly cut the pulp;

[0046] The end of the second knife 130 is at a relatively high position. A spiral blade can be used, which can have a longer cutting edge 101, increasing the contact surface with the pulp, so as to quickly cut larger pieces of pulp.

[0047] In addition, in this embodiment, in order to enable the cutting knife 100 to rotate in both forward and reverse directions, two cutting edges 101 are provided on both the first knife 120 and the second knife 130.

[0048] Refer to Figure 2 As shown, the vertical interface of the blade is set to be triangular in shape, and the two sides along the rotation direction are the cutting edges 101, which can contact the pulp and cut the pulp.

[0049] Embodiment 2

[0050] This embodiment provides a juice extractor, which includes the cutting knife 100 described in Embodiment 1, and further includes a feed barrel 300 and a main machine 200 for driving the cutting knife 100 to rotate;

[0051] A stop block 400 is protrudingly provided on the inner wall of the feed barrel 300. The stop block 400 cooperates with the cutting knife 100 to cut and juice the pulp.

[0052] Specifically refer to Figure 3 and Figure 4 As shown, the upper end of the feed barrel 300 is provided with an opening. The pulp is put into the feed barrel 300, and the main machine 200 is started. The main machine 200 drives the knife holder 500, drives the cutting knife 100 on the knife holder 500 to rotate, cuts the pulp in the feed barrel 300, and extracts juice.

[0053] During the juicing process, the cutting knife 100 rotates with the knife holder 500, and when it contacts the pulp, it generates a push on the pulp. Part of the pulp is cut by the high-speed rotating cutting knife 100, and part is pushed by the cutting knife 100 and rotates together; when it encounters the stop block 400, the stop block 400 stops the pulp, making the pulp unable to continue rotating. Then, the cutting knife 100 cuts this part of the pulp and extracts juice.

[0054] In this embodiment, the driving method of the cutting knife 100 in the main machine 200 is the same as that of the juice extractor in the prior art, and will not be elaborated here.

[0055] In this embodiment, the specific implementation manner of the stop block 400 is: the side facing the center of the feed barrel 300 on the stop block 400 is the stop side, and an avoidance recess 401 for avoiding the blade of the cutting knife 100 is provided on the stop side.

[0056] Specifically refer to Figure 4 As shown, when the pulp moves to the side of the stop block 400 under the drive of the cutting knife 100, most of it is blocked by the stop side and cannot continue to move, while the cutting knife 100 can continue to rotate through the avoidance recess 401, thereby cutting the pulp.

[0057] Preferably, in this embodiment, a stop area 410 is provided on the stop side, and the stop area 410 and the avoidance recess 401 are arranged along the axis direction of the feed barrel 300.

[0058] Preferably, in this embodiment, there are two stop areas 410, which are arranged up and down along the inner wall of the feed barrel 300. The avoidance recess 401 is located between the two stop areas 410, so that the cutting knife 100 can smoothly pass through the avoidance recess 401 for rotation.

[0059] A knife avoidance gap 402 is left between the lower stop area 410 on the stopper 400 and the bottom of the feed barrel 300, and the first knife 120 can pass through the knife avoidance gap 402.

[0060] Refer to Figure 4 and Figure 5 As shown, the first knife 120 is located near the bottom of the barrel body and has a short blade length, usually for cutting the juice at the bottom of the barrel body; the end position of the second knife 130 is higher, and is used for cutting the upper part of the larger pieces of pulp.

[0061] In this embodiment, the blade length of the first knife 120 can be set as a short knife to avoid collision with the lower end of the stopper 400; in this embodiment, to accommodate the first knife 120 of various lengths, a knife avoidance gap 402 is left between the lower stop area 410 on the stopper 400 and the bottom of the barrel body, and the first knife 120 can pass through the knife avoidance gap 402.

[0062] Refer to Figure 5 As shown, a knife avoidance gap 402 that allows the first knife 120 to pass through is left between the lowermost stop area 410 on the stopper 400 and the barrel body, so that the first knife 120 of any length can pass through the stopper 400 for smooth rotation.

[0063] The above are only the preferred embodiments of the present invention, and do not impose any form of limitation on the present invention. Although the present invention has been disclosed above with the preferred embodiments, it is not intended to limit the present invention. Any person skilled in the art can make some changes or modifications to the equivalent embodiments by using the disclosed technical content within the scope of the technical solution of the present invention. However, as long as it does not depart from the content of the technical solution of the present invention, any brief modifications, equivalent changes and modifications made to the above embodiments based on the technical essence of the present invention still fall within the scope of the technical solution of the present invention.
