[0001] The utility model relates to a component of a juice extractor, and more specifically, to a juice extraction assembly of a juice extractor. The utility model also relates to a juice extractor adopting the assembly. Background Art

[0002] The juice extractor is developed on the basis of the conventional juicer, and their main working purpose is to turn fruits into juice to improve the taste and facilitate drinking. However, the juice extractor has made a qualitative leap on the basis of the traditional cup blender and juicer. The low-speed screw extrusion technology of the juice extractor squeezes out the juice slowly 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 oxidation due to heat.

[0003] The core components of the juice extractor are the screw assembly and the filter screen assembly that cooperate with each other. With the continuous development of technology and the continuous improvement of user requirements, the juice extractor is also constantly innovated. In the existing screw assembly, in order to directly juice large-sized fruits and vegetables, a pre-crushing cutter head is connected to the upper end of the screw, and the fruits and vegetables are pre-cut and crushed by the pre-crushing cutter head. The outer end face of the existing pre-crushing cutter head is very smooth, and it only has the function of rough crushing, but it cannot scrape the materials. In actual use, it is found that the materials are often stuck and cannot move downward. Summary of the Utility Model

Specific embodiments

[0026] Refer to Figures 1 to 4 As shown, a juice extractor assembly of the present utility model includes a screw 1 and a feeding and grinding device 2 that cooperate with each other. The feeding and grinding device 2 is composed of a grinding and filtering part 2a, a connecting part 2b, and a bin part 2c arranged in sequence from bottom to top. The connecting part 2b is integrally in the shape of an inverted frustum. The connecting part is used to smoothly connect the bin part and the grinding filter to achieve juice extraction of large-diameter fruits and vegetables.

[0027] The screw 1 includes a seat body 1a. A spiral cutting and extrusion rib 1b is arranged circumferentially on the outer wall of the seat body 1a. A pre-crushing cutter head 3 with a spiral upward is arranged at the upper end of the seat body 1a. A plurality of scraping ribs 4 are integrally formed outside the pre-crushing cutter head 3, and the scraping ribs 4 cooperate to form a serrated shape. Through the serrated scraping ribs, the pushing of the material can be realized to prevent it from staying in the connecting part and not falling. At the same time, the vertical projection of the upper end of the pre-crushing cutter head 3 is located outside the vertical projection of the lower outer contour of the seat body 1a. That is, when the pre-crushing cutter head rotates, the diameter of the circle formed by the rotation of its upper end is larger than the diameter of the lower end of the base. The upper end of the pre-crushing cutter head is not limited to the end, generally referring to a certain range near the end, which is easy for those skilled in the art to think of. The specific range value can be determined according to the product requirements. This structure can make the pre-crushing cutter head adapt to the inner diameter of the bin part and make the pre-crushing effect better.

[0028] Preferably, the scraping rib 4 is triangular and the sides connected to the seat body and the outer side opposite to the feeding and grinding device 2 are arc-shaped; the scraping ribs 4 are sequentially reduced from top to bottom. The sequential reduction of the scraping ribs is arranged in cooperation with the inverted frustum-shaped connecting part, and the scraping ribs can be as close as possible to the inner wall of the connecting part, so as to achieve effective scraping.

[0029] Further preferably, a spoiler block 2d that inclines downward along the rotation direction of the screw 1 is integrally formed on the inner wall of the connecting portion 2b, and the upper ends of the scraping ribs 4 are matched with the spoiler block 2d at the corresponding position. The spoiler block arranged obliquely can guide the fruits and vegetables to move downward, and the phenomenon of idling will not occur, which can further improve the efficiency of the material falling.

[0030] In this embodiment, the seat body 1a is in the shape of a frustum of a cone with a smaller upper part and a larger lower part. The pre-crushing cutter head 3 is integrally formed on one side of the upper end of the seat body 1a, and the lower edge of the pre-crushing cutter head 3 is smoothly transitioned with the seat body 1a. The arrangement of the seat body and the pre-crushing cutter head not only realizes the crushing of fruits and vegetables, but also can prevent the fruits and vegetables from staying at the contact part of the two.

[0031] Preferably, the cutting and extruding rib 1b is composed of a plurality of extrusion strips 1c arranged at intervals. Based on the above concept, the cutting and extruding strips can be arranged in a spiral shape or slightly staggered, as long as the whole is spiral and can guide the material to move downward. The segmented cutting and extruding rib can not only make the material move downward quickly, but also make the pressure evenly distributed when the material moves downward. Not only the juice extraction efficiency is high, but also the juice extraction component is not easily damaged, especially the filter screen, which will not be damaged due to excessive pressure.

[0032] Further preferably, the length of the extrusion strip 1c is 3 - 150 mm. It depends on the product specifications and requirements specifically.

[0033] Further preferably, the high-end end face of the extrusion strip 1c is an inclined surface that inclines towards the advancing direction of the material. The inclined surface structure can facilitate the downward guiding of the material. At the same time, the tip formed by the inclined surface and the upper end face is convenient for cutting and crushing fruits and vegetables, so that they can be decomposed into smaller pieces more quickly.

[0034] Further preferably, a positioning boss 5 that cooperates with the feeding and grinding device 2 is arranged near the end of the lower part of the seat body 1a, and a first slag discharge port 6 is formed between two adjacent positioning bosses 5. At the same time, supporting lugs 5a are arranged at both ends of the positioning boss 5 along the length direction, and the lower end of the feeding and grinding device 2 contacts the supporting lugs 5a and cooperates with the positioning boss 5 to form a second slag discharge port 5b.

[0035] Adopting this structure can effectively discharge the slag of the juice extraction component and prevent the fruit and vegetable residues from staying on the positioning boss.

[0036] Refer to Figure 5 and Figure 6As shown in the figure, a juice extractor of the present utility model adopting the above-mentioned juice extraction assembly includes a main body 7, a pressing cup 8 is detachably connected to the main body 7, a feeding and grinding device 2 is detachably connected to the pressing cup 8, a screw 1 is arranged in the feeding and grinding device 2 and is connected and linked with the output shaft of the driving device in the main body 7. Its usage method and working principle are the same as those of the prior art and will not be elaborated here.

[0037] The above-mentioned embodiments are the preferred embodiments of the present utility model, which are only used to conveniently illustrate the present utility model and do not impose any formal restrictions on the present utility model. Any person with ordinary knowledge in the technical field, without departing from the technical features of the present utility model, using the technical content disclosed by the present utility model to make local changes or modified equivalent embodiments, and without departing from the technical feature content of the present utility model, still belong to the scope of the technical features of the present utility model.
