Description

Technical Field

[0001] The utility model relates to a juice extraction assembly and a juice extractor. Background Art

[0002] At present, with the continuous improvement of people's living standards, juice extractors have been widely popularized in people's daily lives. A juice extractor includes a juice extraction cup, a spiral propeller rotatably arranged inside the juice extraction cup, and a motor arranged below the juice extraction cup and driving the spiral propeller to rotate. During operation, fruits or vegetables are put into the juice extraction cup from the feeding port, and the motor drives the spiral propeller to rotate to cooperate with the inner peripheral wall of the juice extraction cup to crush the fruits or vegetables. At the same time, under the action of the spiral ribs of the spiral propeller, the fruit residues or vegetable residues are crushed and ground from top to bottom by the spiral ribs. The juice comes out from the mesh holes inside the juice extraction cup, enters the juice receiving groove, and then is discharged from the juice discharge port inside the juice receiving groove, while the residues are pushed by the spiral propeller to the bottom of the juice extraction cup and discharged from the residue discharge port at the bottom of the juice extraction cup component.

[0003] Among them, the spiral ribs are subjected to the reaction force from the fruit residues or vegetable residues from bottom to top, resulting in a vertical upward displacement or slight crosstalk of the spiral propeller, affecting the stability of the grinding ability of the spiral propeller, and thus affecting the juice yield. In order to limit the upward displacement of the spiral propeller, the current method is to provide a flange at the lower end of the spiral propeller. The flange repeatedly abuts against the lower end face of the juice extraction cup upward while rotating, and it is easy to generate grinding plastic debris and enter the juice, affecting food safety. Moreover, as the use time goes by, the increase in the wear amount will lead to an increase in the amplitude of the up and down crosstalk of the spiral propeller, and finally result in a lower juice yield.

The examples of the embodiments are shown in the drawings, where the same or similar reference numerals represent the same or similar elements or elements with the same or similar functions throughout. The embodiments described below with reference to the drawings are exemplary and are only used to explain the present invention and should not be construed as a limitation of the present invention.

If there is a description of "first" and "second", it is only for the purpose of distinguishing technical features and should not be understood as indicating or implying relative importance or implicitly indicating the quantity of the indicated technical features or implicitly indicating the sequence relationship of the indicated technical features.

[0030] In the description of the present invention, it should be noted that unless otherwise clearly specified and limited, the terms "installation", "connection", and "connection" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be directly connected or indirectly connected through an intermediate medium, and it can be the communication inside two elements. For those of ordinary skill in the art, the specific meanings of the above terms in the present invention can be understood according to specific situations.

[0031] See Figure 1 and Figure 2 or see Figure 5 and Figure 6, a juice extraction assembly of the present utility model includes: a juice extraction cup 100, inside which there is a vertically arranged and cylindrical juice extraction channel 110, and an annular metal part 200 is fixedly arranged on the inner peripheral wall of the upper or lower part of the juice extraction channel 110; a screw propeller 300, rotatably arranged within the juice extraction cup 100 around the axis of the juice extraction channel 110, and the screw propeller 300 has a screw rib section 310 that cooperates with the inner wall of the juice extraction channel 110; a metal limiting part 400, arranged on the screw propeller 300 and located below the annular metal part 200, and the metal limiting part 400 can rotate with the screw propeller 300 and abut upward against the annular metal part 200 to limit the upward movement of the screw propeller 300 relative to the juice extraction cup 100.

[0032] When the screw propeller 300 of the juice extraction assembly with the above structure is subjected to the reaction force of the food material from bottom to top, the screw propeller 300 moves slightly upward so that the metal limiting part 400 abuts upward against the preset annular metal part 200 in the juice extraction channel 110. No plastic debris will enter the juice when the metal limiting part 400 and the annular metal part 200 are in contact, which is beneficial to solving the food safety problem; the loss when the metal limiting part 400 and the annular metal part 200 are in contact is small, that is, the amplitude of the up and down movement of the screw propeller 300 relative to the juice extraction cup 100 is small and stable, alleviating the problem that the grinding efficiency and working stability of the screw propeller 300 are affected by repeated up and down movement, and ensuring the grinding efficiency and working stability of the juice extraction assembly. In addition, whether the metal limiting part 400 is located above or below the screw rib section 310 will not affect the cooperation between the screw rib section 310 and the juice extraction channel 110.

[0033] See Figure 2, in some embodiments of the present utility model, an inner peripheral wall of an upper portion of the juice extraction channel 110 is provided with a first annular step protruding inward along its radial direction. The first annular step includes a horizontally arranged annular bottom wall and an annular inner wall connected to an inner peripheral edge of the annular bottom wall and arranged vertically upward. The annular metal part 200 includes a first annular plate portion 210 attached to a lower end surface of the annular bottom wall. There is a gap between the screw propeller 300 and the annular inner wall for food materials to enter the juice extraction channel 110. The metal limiting part 400 can abut upward against the first annular plate portion 210. It should be noted that a radial gap between an upper portion of the spiral rib segment 310 and the juice extraction channel 110 is larger than a radial gap between a lower portion of the spiral rib segment 310 and the juice extraction channel 110 to achieve the effect of grinding food materials to extract juice. Therefore, the first annular step, the annular metal part 200 and the metal limiting part 400 being arranged above the spiral rib segment 310 can avoid affecting the normal grinding work of the screw propeller 300, and the food materials to be juiced can enter the juice extraction channel 110 from the gap between the screw propeller 300 and the annular inner wall.

[0034] See Figure 1 and Figure 2 , in some embodiments of the present utility model, the annular metal part 200 further includes a second annular plate portion 220 connected to an inner peripheral edge of the first annular plate portion 210 and extending vertically upward. The juice extraction cup 100 is made of plastic material. The annular bottom wall and the annular inner wall are respectively welded and fixed to the first annular plate portion 210 and the second annular plate portion 220. It can be understood that it is difficult to ensure that the annular metal part 200 is not easily detached from the force by attaching the first annular plate portion 210 to the surface of the annular bottom wall. Therefore, the first annular plate portion 210 and the second annular plate portion 220 made of metal material form the annular metal part 200. Connecting the second annular plate portion 220 to the annular inner wall can increase the contact area and the difficulty of the annular metal part 200 falling off. And when the annular metal part 200 is placed in a mold to injection mold the juice extraction cup 100, the annular bottom wall and the annular inner wall can be respectively welded and fixed to the first annular plate portion 210 and the second annular plate portion 220, with extremely high firmness.

[0035] See Figure 3 and Figure 4, in some embodiments of the present utility model, the metal limiting member 400 is a cutting blade. The cutting blade has a flat plate portion 410 that can abut against the first circular ring plate portion 210. An inclined cutting slope 420 is provided on one side edge of the flat plate portion 410. The cutting slope 420 cooperates with the first circular ring plate portion 210 to break the food material. It can be understood that when the screw propeller 300 receives the upward reaction force from the food material, the flat plate portion 410 abuts upward against the first circular ring plate portion 210. Since the cutting blade rotates together with the screw propeller 300, a cutting edge is formed at the ridge line where the cutting slope 420 and the flat plate portion 410 intersect. When rotating, the cutting edge can cooperate with the first circular ring plate portion 210 to break the downward moving food material, thereby preventing long strip-shaped food materials from winding around the surface of the screw propeller 300, which is beneficial to reducing the load of the motor for driving the rotation of the screw propeller 300 and improving the juicing efficiency.

[0036] See Figure 3 and Figure 4 , in some embodiments of the present utility model, the screw propeller 300 is made of plastic material. The screw propeller 300 is wrapped outside the mounting bracket 430. A plurality of the cutting blades are evenly distributed in a circumferential direction around the axis of the juice extraction channel 110 on the mounting bracket 430 and protrude from the side wall of the screw propeller 300. Among them, the mounting bracket 430 and the plurality of cutting blades are of an integral metal structure. The whole composed of the mounting bracket 430 and the plurality of cutting blades is first placed in an injection mold, and then injection molding is carried out to obtain the screw propeller 300 while fixing the mounting bracket 430 inside the screw propeller 300, which helps to simplify the assembly process between the cutting blade and the screw propeller 300.

[0037] See Figure 1 and Figure 2 , in some embodiments of the present utility model, the juice extraction cup 100 has a frustum-shaped sleeve 120 that is wider at the top and narrower at the bottom and is connected to the upper end of the juice extraction channel 110. The first annular step is provided at the junction of the frustum-shaped sleeve 120 and the juice extraction channel 110. The screw propeller 300 has a spiral stirring section 320 that extends upward into the frustum-shaped sleeve 120. It can be understood that the food material is put in from the larger end of the frustum-shaped sleeve 120, is broken or interrupted by the spiral stirring section 320 in the frustum-shaped sleeve 120, and then enters the juice extraction channel 110 and is ground by the spiral rib section 310 to form juice and residue.

[0038] It should be noted that if only one metal limiting member 400 is provided, it is easy to cause a slight lateral tilt of the screw propeller 300 relative to the juice extraction cup 100, which is not conducive to force balance and the smooth rotation of the screw propeller 300. Therefore, in some embodiments of the present utility model, see Figure 1Or refer to Figure 5 , at least two metal limit members 400 are provided, and all the metal limit members 400 are evenly distributed in a circumferential manner around the axis of the juice extraction channel 110.

[0039] Refer to Figure 1 , in some embodiments of the present invention, at least one horizontal shaft member 440 is fixedly provided at a position corresponding to the upper part of the juice extraction channel 110 of the screw propeller 300. Both ends of the horizontal shaft member 440 penetrate through the screw propeller 300 along the radial direction of the juice extraction channel 110. Both ends of the horizontal shaft member 440 extending out of the outer peripheral wall of the screw propeller 300 constitute the two metal limit members 400, which is beneficial to simplifying the structure and the production and assembly process.

[0040] Refer to Figure 5 and Figure 6 , in some embodiments of the present invention, a second annular step is formed upward on the inner peripheral wall at the lower end of the juice extraction channel 110 and is arranged radially outward along the juice extraction channel 110. The annular metal member 200 is fixedly arranged on the lower end surface of the second annular step. The metal limit member 400 is a metal convex column protruding from the outer peripheral wall at the lower end of the screw propeller 300. When the screw propeller 300 receives an upward reaction force from the food material, the metal convex column can abut upward against the annular metal member 200 of the second annular step. The structure is very simple and does not affect the grinding of the food material by the spiral rib section 310.

[0041] The present invention also discloses a juice extractor, including the juice extraction assembly of any of the above technical solutions; the juice extractor has relatively high grinding efficiency and stability and is beneficial to food safety.

[0042] The technical features of the above embodiments can be combined arbitrarily. For the sake of concise description, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, it should be considered as the scope recorded in this specification.

[0043] Although the embodiments of the present invention have been shown and described, those of ordinary skill in the art can understand that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principle and purpose of the present invention. The scope of the present invention is defined by the claims and their equivalents.
