Description

Technical Field

[0001] This utility model relates to an assembly structure for a juicer component, and more specifically, to an assembly structure for a juice collection cup and a screw. This utility model also relates to a juicer employing this structure. Background Technology

[0002] Slow juicers evolved from conventional juicers, and their main purpose is to turn fruit into juice to improve taste and make it more convenient to drink. The slow juicer's low-speed spiral extrusion technology squeezes the juice out slowly, like squeezing a towel, without damaging the fruit's cell structure, thus preserving its nutrients. Furthermore, the low-speed juicing process avoids generating high heat, preventing the juice from oxidizing due to heat.

[0003] Currently, in down-press juicers, the limiting ring or boss at the bottom of the screw is located at the lower end, although some may have it located near the lower end. The purpose is to form a sealing ring below the limiting ring or boss. However, during research and development, it was discovered that for some fruits and vegetables with high water content and low fiber, after the juice is extracted, some of it seeps back into the pulp at the bottom of the juicing gap between the juice collection cup and the screw. This is because there is no further compression structure at the lower end of the screw. Utility Model Content

[0004] The primary objective of this invention is to address the shortcomings of the prior art by providing a compact assembly structure for the juice collection cup and screw, which offers excellent juicing results. The secondary objective of this invention is to provide a juicer employing the aforementioned structure.

[0005] The preceding technical solution of this utility model is implemented as follows: an assembly structure of a juice collecting cup and a screw, including a juice collecting cup, wherein a convex ring is provided on the bottom edge of the juice collecting cup, and a slag outlet is provided on the convex ring and the bottom area of ​​the juice collecting cup on the side of the convex ring; and a number of extrusion ribs are distributed circumferentially at intervals on the side wall of the convex ring. A screw is detachably connected inside the juice collection cup. Several limiting bosses that cooperate with the convex ring are distributed circumferentially on the outer wall near the lower end of the screw. Several extrusion protrusions that cooperate with the extrusion ribs are distributed on the outer wall of the screw between the lower end face of the limiting boss and the lower end face or near the lower end. The two surfaces of the extrusion protrusions and the extrusion ribs cooperate to extrude the fruit pulp to reduce its moisture content.

[0006] In the above-mentioned assembly structure of the juice collection cup and the screw, the front end face of the extrusion protrusion facing the rotation direction is a feeding slope.

[0007] In the above-mentioned assembly structure of the juice collection cup and the screw, the outer wall of the screw between the lower end face of the limiting boss and the lower end face or the near end of the lower end is an inverted frustum shape with a larger upper part and a smaller lower part, and the extrusion protrusion is integrally formed on the outer wall of the inverted frustum shape.

[0008] In the above-mentioned assembly structure of the juice collecting cup and the screw, the outer end face of the extrusion protrusion and the outer surface of the screw seat in the area where the limiting protrusion is located are on the same arc surface.

[0009] In the above-mentioned assembly structure of a juice collecting cup and a screw, a sealing ring is provided on the bottom end face of the screw, and a sealing groove that cooperates with the sealing ring is provided at the bottom of the juice collecting cup.

[0010] The latter technical solution of this utility model is implemented as follows: A juicer using the above-mentioned assembly structure includes a main base, a cup assembly detachably connected to the main base, the cup assembly including a juice collection cup detachably connected to the main base, a screw rotatably connected inside the juice collection cup, and a feeding grinder arranged around the screw. The feeding grinder is detachably connected to the juice collection cup and cooperates with the screw to crush and squeeze the material to extract juice.

[0011] In the juicer described above, the screw includes a base body, and spiral extrusion ribs are distributed circumferentially on the outer wall of the base body; a pre-cutting blade is provided at the upper end of the base body, the pre-cutting blade includes a blade head, the blade head is inclined upward, and a scraping part that cooperates with the inner wall of the corresponding material bin is provided on the side of the blade head away from the blade edge.

[0012] In the juicer described above, the blade head consists of a long blade at the top and a pointed blade at the bottom; the scraping part is located at the back of the blade head.

[0013] In the juicer described above, the scraper and the blade are integrally formed.

[0014] In the juicer described above, the pre-cutting blade includes a connecting seat, and the blade head and the horizontal cutting part are both disposed on the connecting seat, and the connecting seat, the blade head and the horizontal cutting part are integrally formed as a whole structure; the connecting seat is connected to the seat body by fasteners.

[0015] After adopting the above structure, this utility model sets a squeezing protrusion under the limiting protrusion. The squeezing protrusion and the squeezing rib work together to squeeze the bottom fruit residue. This not only reduces the backflow of juice, but also allows for the final juicing of the fruit residue, thereby achieving the purpose of reducing the moisture content in the residue.

[0023] See Figures 1 to 3 As shown, the present invention provides an assembly structure of a juice collecting cup and a screw, including a juice collecting cup 1, a raised ring 2 provided on the bottom edge of the juice collecting cup 1, a slag outlet 1a provided on the raised ring 2 and the bottom area of ​​the juice collecting cup 1 on the side of the raised ring 2; and a plurality of extrusion ribs 2a distributed circumferentially on the side wall of the raised ring 2.

[0024] A screw 3 is detachably connected inside the juice collection cup 1. Several limiting bosses 3a, which cooperate with the convex rings 2, are distributed circumferentially along the outer wall of the lower end of the screw 3 near its tip. Several extrusion protrusions 3b, which cooperate with the extrusion ribs 2a, are distributed on the outer wall of the screw 3 between the lower end face of the limiting bosses 3a and the lower end face or near its tip. The two surfaces of the extrusion protrusions 3b and the extrusion ribs 2a cooperate to extrude juice from the pulp, reducing its moisture content. By setting extrusion protrusions below the limiting bosses, and by using the extrusion protrusions and extrusion ribs to extrude juice from the bottom pulp, not only can juice backflow be reduced, but the pulp can also be juiced in the final stage.

[0025] More preferably, the front end face of the extrusion protrusion 3b facing the rotation direction is a feeding ramp 3c. The feeding ramp allows the material to enter the bottom extrusion area more smoothly.

[0026] More preferably, the outer wall of the screw 3, from the lower end face of the limiting boss 3a to the lower end face or near the lower end of the screw 3, is an inverted frustum shape, wider at the top and narrower at the bottom, and the extrusion protrusion 3b is integrally formed on the outer wall of this inverted frustum shape. Simultaneously, the outer end face of the extrusion protrusion 3b and the outer surface of the screw 3 seat body in the area where the limiting boss 3a is located are on the same arc surface.

[0027] By cleverly designing the extrusion protrusion at the inverted frustum position, the overall structure remains compact while simultaneously achieving the desired squeeze. Because the extrusion protrusion is cleverly positioned at the inverted frustum location, it avoids outward protrusion, thus minimizing dimensional variations at the bottom of the juice collection cup.

[0028] More preferably, to ensure sealing and prevent leakage, a sealing ring 4 is provided on the bottom end face of the screw 3, and a sealing groove 1b that cooperates with the sealing ring 4 is provided at the bottom of the juice collection cup 1.

[0029] See Figures 1 to 5 As shown, this utility model discloses a juicer employing the above-described assembly structure, comprising a main unit base 5, on which a cup assembly 6 is detachably connected. The cup assembly 6 includes a juice collection cup 1 detachably connected to the main unit base 5, a screw 3 rotatably connected inside the juice collection cup 1, and a feeding grinder 7 disposed around the screw 3. The feeding grinder 7 is detachably connected to the juice collection cup 1 and cooperates with the screw 3 to crush and squeeze the material to extract juice. During assembly, the lower end face of the feeding grinder cooperates with a convex ring to clamp and limit a limiting boss, allowing the limiting boss to rotate but preventing it from moving up and down.

[0030] Preferably, the screw 3 includes a base 3d, and spiral extrusion ribs 3e are distributed circumferentially on the outer wall of the base 3d; a pre-cutting blade 8 is provided at the upper end of the base 3d, the pre-cutting blade 8 includes a blade head 8a, the blade head is inclined upward, and a scraping part 8b that cooperates with the inner wall of the corresponding hopper is provided on the side of the blade head 8a away from the blade.

[0031] By incorporating a scraping section, material adhering to the corresponding position at the bottom of the hopper can be scraped and fed into the lower juicing section. Furthermore, it should be noted that, based on the aforementioned function of the scraping section, those skilled in the art can employ various shapes or structures to achieve this. It can be integrally formed with the pre-cutting blade; when integrally formed, the scraping section generally needs to be spaced a certain distance from the inner wall of the hopper, preferably 1-5mm. Alternatively, it can be a separate design, such as connecting a silicone scraper to the blade head, which allows for thorough scraping. When using a silicone scraper, the scraper can make close contact with the inner wall of the hopper. The specific design can be reasonably determined by those skilled in the art through numerous tests based on its function.

[0032] More preferably, the cutting edge of the cutter head 8a consists of a long blade 8c at the top and a pointed blade 8d at the bottom; the scraping part 8b is located at the back of the cutter head 8a. The pointed blade can better break up the material, and the long blade has a long contact surface with the material, which can cut the material more quickly.

[0033] More preferably, the scraper part 8b and the cutter head 8a are integrally formed. Of course, as mentioned above, in order to scrape more cleanly, the scraper part can also be a separate silicone scraper or other alternatives that are easily conceived by those skilled in the art.

[0034] More preferably, the pre-cutting blade 8 includes a connecting seat 8e, and the cutting head 8a is disposed on the connecting seat 8e, with the connecting seat 8e and the cutting head 8a being an integrally formed structure; the connecting seat 8e is connected to the base body 3d by fasteners. That is, the pre-cutting blade and the base body are separate structures. As those skilled in the art would readily conceive of, a separate design is an equivalent alternative to integral molding.

[0035] During operation, the material is juiced by the screw and the feeding grinder. Finally, under the action of the screw's extrusion ribs, it moves towards the bottom and enters the bottom of the screw after passing the limiting boss. Then, it is squeezed by the extrusion protrusion and extrusion ribs, making the material more compact and preventing juice from seeping back. At the same time, it can further squeeze out the juice.

[0036] The above-described embodiments are preferred embodiments of the present utility model and are only used to facilitate the illustration of the present utility model. They are not intended to limit the present utility model in any way. Any person skilled in the art who makes partial modifications or alterations to the technical content disclosed in the present utility model without departing from the scope of the technical features of the present utility model shall still fall within the scope of the technical features of the present utility model.
