Description

Technical Field

[0001] This utility model relates to the field of kitchen equipment technology, and in particular to a juicer that is easy to clean. Background Technology

[0002] Slow juicers evolved from conventional juicers, their primary purpose being to turn fruits and vegetables into juice to improve taste and facilitate consumption. However, slow juicers first pulverize the ingredients with blades, then squeeze the juice through a gap formed between a screw-type pusher and a filter cup. Finally, the juice flows out through filter holes on the filter cup's wall, completing the separation of pulp and juice. The principle is similar to squeezing a towel, slowly extracting the juice without damaging the cell structure of the ingredients, thus preserving nutrients. Furthermore, the low-speed juicing process avoids high heat generation and prevents juice oxidation. However, currently, most slow juicers on the market use metal mesh filter cups. While this achieves filtration, food residue easily gets trapped in the mesh, making cleaning very difficult. Moreover, the metal surface is easily scraped off during use and cleaning. Utility Model Content

[0003] The purpose of this invention is to design a juicer that is easy to clean in order to overcome the shortcomings of the above-mentioned technology.

[0004] This utility model designs an easy-to-clean juicer, including a base, a squeezing and filtering chamber, and a feed hopper. A motor is installed inside the base. The squeezing and filtering chamber is connected to the upper end of the base, and the feed hopper is connected to the upper end of the squeezing and filtering chamber. A filter cup is installed inside the squeezing and filtering chamber, and a threaded pusher is installed inside the filter cup. A first rotating shaft is located at the center of the threaded pusher. An end cap is provided at the upper end of the base, and a first through hole is provided on the end cap. The output shaft of the motor passes through the first through hole and is connected to one end of the first rotating shaft of the threaded pusher. A second rotating shaft is coaxially connected to the other end of the first rotating shaft. The second rotating shaft extends into the feed hopper and is connected to a pulverizing blade. The filter cup is made of plastic, and several funnel-shaped filter holes are distributed on the peripheral wall of the filter cup. A squeezing space for squeezing food is formed between the threaded pusher and the inner wall of the filter cup.

[0005] Preferably, the diameter of the filter hole located on the inner wall of the filter cup is smaller than the diameter located on the outer wall of the filter cup.

[0006] Further optimization involves providing an installation groove at the bottom of the extrusion filter chamber, where the bottom of the filter cup and the bottom of the threaded pusher are both embedded.

[0007] Further optimization includes an opening at the center of the bottom of the filter cup, a mounting post at the center of the mounting groove of the extrusion filter chamber, a mounting post at the bottom of the threaded pusher forming a matching concave hole, a through hole for the first rotating shaft to pass through on the mounting post, and a sealing ring between the through hole and the first rotating shaft.

[0008] Further optimization includes a circumferential cup bottom along the opening of the filter cup, with a first circumferential groove on the inner surface of the cup bottom, and a first protruding ring at the bottom of the threaded pusher that engages with the first circumferential groove; a second circumferential groove parallel to the first protruding ring is provided on the bottom end face of the threaded pusher, and a second protruding ring at the edge of the opening of the cup bottom that engages with the second circumferential groove; a third circumferential groove parallel to the second circumferential groove is also provided on the bottom end face of the threaded pusher, and a third protruding ring engaging with the third circumferential groove is provided on the bottom surface of the mounting groove.

[0009] Further optimization involves providing a limiting protrusion on the outer surface of the cup bottom, and a limiting groove in the mounting groove that forms a limiting fit with the limiting protrusion.

[0010] Further optimization involves providing a first slag discharge port at the bottom of the extrusion filter chamber that communicates with the mounting groove, and a second slag discharge port at the bottom of the cup that communicates with the first slag discharge port. The connection between the second slag discharge port and the first circumferential groove forms an inclined guide surface, facilitating the falling of food residue into the second slag discharge port.

[0011] Preferably, the inner peripheral wall of the filter cup is provided with a plurality of vertically extending grinding ridges, which are located in the lower half of the filter cup in the height direction, and the height of each grinding ridge gradually decreases from the top to the bottom.

[0012] Further optimization involves the distribution of filter holes between adjacent grinding ridges.

[0013] Preferably, the outer peripheral wall at the bottom of the hopper is provided with a protrusion, and the inner peripheral wall at the top of the extrusion filter chamber is provided with a groove that matches the protrusion. An inlet for the protrusion to slide into is provided on the side of the groove.

[0014] The technical advantages of this invention are as follows: the filter cup is made of plastic, unlike the metal mesh filter cups on the market. It is not only easy to clean, but also does not pose a risk of metal surface peeling off during long-term use and cleaning. The filter cup has funnel-shaped filter holes, with a small diameter at the inner wall and a large diameter at the outer wall. This allows juice to pass through the filter holes while preventing food residue from entering. If the filter holes were not designed as small-diameter cylindrical holes, although food residue could be prevented, it would be difficult for the juice to pass through, requiring greater pressure to push the juice from the inner wall to the outer wall. In this invention, the outer wall is designed as a large-diameter end, so the juice can be discharged from the large-diameter end without much pressure after entering from the small-diameter end, which is very convenient. Therefore, the juice drainage effect is excellent, and it is also easy to clean. Attached Figure Description

Detailed Implementation

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model are within the protection scope of the present utility model.

[0024] This utility model is a juicer, which mainly includes a base 1, a squeezing and filtering chamber 2, and a hopper 3. A motor is installed in the base 1. The squeezing and filtering chamber 2 is connected to the upper end of the base 1, and the hopper 3 is connected to the upper end of the squeezing and filtering chamber 2. A filter cup 4 is installed in the squeezing and filtering chamber 2, and a threaded pusher 5 is installed in the filter cup 4. A first rotating shaft 6 is installed in the center of the threaded pusher 5. An end cover 7 is installed at the upper end of the base 1, and a first through hole 8 is provided on the end cover 7. The output shaft of the motor passes through the first through hole 8 and is connected to one end of the first rotating shaft 6 of the threaded pusher 5. A second rotating shaft 9 is coaxially connected to the other end of the first rotating shaft 6. The second rotating shaft 9 extends into the hopper 3 and is connected to a crushing blade 10. The motor drives the first rotating shaft 6 to rotate, the first rotating shaft 6 drives the threaded pusher 5 to rotate, and synchronously drives the second rotating shaft 9 to rotate. The second rotating shaft 9 drives the crushing blade 10 to rotate, so that the crushing blade 10 crushes the food, and then the food is squeezed by the threaded pusher 5.

[0025] The filter cup 4 has several filter holes 11 distributed on its peripheral wall. The screw pusher 5 and the inner wall of the filter cup 4 form a squeezing space 12 for squeezing the food. The inner peripheral wall of the filter cup 4 is provided with multiple vertically extending grinding ridges 31, which are spaced apart. After the food enters the feed hopper 3 and is crushed by the crusher 10, it falls into the squeezing space 12. The surface of the screw pusher 5 is provided with screw-shaped grinding ribs. The screw pusher 5 rotates and drives the grinding ribs to rotate, so that the grinding ribs and the grinding ridges 31 form relative compression, thereby squeezing the crushed food to extract juice.

[0026] The filter cup 4 is made of plastic. The plastic material of the filter cup 4 not only makes it easy to open the filter holes 11, but also makes it easy to manufacture. In addition, the plastic material will not rust and is easy to clean.

[0027] The filter hole 11 is a funnel-shaped hole. The diameter of the filter hole 11 on the inner wall of the filter cup 4 is smaller than the diameter on the outer wall of the filter cup 4. That is, the port of the filter hole 11 on the inner wall is the small diameter end, and the port on the outer wall is the large diameter end. In this way, the squeezed juice enters the large diameter end after passing through the small diameter end. This design allows the juice to pass through the filter hole 11 while preventing food residue from entering the filter hole 11. If the filter hole 11 is not designed as a small diameter cylindrical hole, although it can prevent food residue, it is more difficult for the juice to pass through the filter hole 11. It requires a large pressure to push the juice from the inner wall end to the outer wall end. In this utility model, the outer wall end is designed as a large diameter end. After the juice enters from the small diameter end, it can be discharged from the large diameter end without much pressure, which is very convenient. Therefore, the juice discharge effect is very good, and it is also easy to clean.

[0028] Furthermore, the filter cup 4 is funnel-shaped, meaning that the radial dimension gradually increases from the bottom to the top. This not only facilitates the squeezing of the inner wall with the threaded pusher 5, but also makes it easier for the juice to drain.

[0029] Furthermore, the bottom of the extrusion filter chamber 2 is provided with an installation groove 13, and the bottom surface of the extrusion filter section is provided with a circumferential protrusion. The circumferential protrusion surrounds and forms a circular installation groove 13. The bottom of the filter cup 4 and the bottom of the threaded pusher 5 are both embedded in the installation groove 13.

[0030] Furthermore, the filter cup 4 has an opening 14 at the center of its bottom, and the installation groove 13 of the extrusion filter chamber 2 has an installation post 15 integrated with the extrusion filter chamber 2 at its center. The bottom of the threaded pusher 5 has an installation post 15 forming a matching recess 16. The installation post 15 is inserted into the recess 16 to position the threaded pusher 5. The installation post 15 has a through hole 17 for the first rotating shaft 6 to pass through, and a sealing ring 18 is provided between the through hole 17 and the first rotating shaft 6.

[0031] Furthermore, the bottom of the filter cup 4 has a circumferential cup bottom 19 along the opening 14. The inner surface of the cup bottom 19 is provided with a first circumferential groove 20. The bottom of the threaded pusher 5 is provided with a first convex ring 21 that engages with the first circumferential groove 20. The bottom end face of the threaded pusher 5 is provided with a second circumferential groove 22 parallel to the first convex ring 21. The cup bottom 19 is provided with a second convex ring 23 that engages with the second circumferential groove 22 at the edge of the opening 14. The bottom end face of the threaded pusher 5 is also provided with a third circumferential groove 24 parallel to the second circumferential groove 22. The bottom surface of the mounting groove 13 is provided with a third convex ring 25 that engages with the third circumferential groove 24. These three sets of concave-convex mating structures—the first circumferential groove 20 and the first convex ring 21, the second circumferential groove 22 and the second convex ring 23, and the third circumferential groove 24 and the third convex ring 25—ensure that the filter cup 4 and the threaded pusher 5 can be stably installed in the extrusion filter chamber 2.

[0032] Furthermore, the bottom of the cup 19 is provided with a limiting protrusion 26 on its outer surface, and the mounting groove 13 is provided with a limiting groove 27 that forms a limiting fit with the limiting protrusion 26. The limiting protrusion 26 is inserted into the limiting groove 27 to form a radial limit, so that the filter cup 4 can be stably installed in the compression filter chamber 2 and prevent the filter cup 4 from rotating.

[0033] Furthermore, the bottom of the extrusion filter chamber 2 is provided with a first slag outlet 28 that communicates with the mounting groove 13, and the bottom of the cup bottom 19 is provided with a second slag outlet 29 that communicates with the first slag outlet 28. The connection between the second slag outlet 29 and the first circumferential groove 20 forms an inclined guide surface 30, which facilitates the food residue to fall into the second slag outlet 29.

[0034] Furthermore, the grinding ridge 31 is located in the lower half of the filter cup 4 in the height direction. The height of each grinding ridge 31 gradually decreases from the top to the bottom, so that the extrusion space 12 also gradually decreases from the top to the bottom, which is conducive to extrusion from top to bottom.

[0035] Furthermore, filter holes 11 are distributed between two adjacent grinding ridges 31, so that when the grinding ridges 31 and the grinding ribs are squeezed together, the juice on the food residue can flow out from the filter holes 11 when the food residue is located between two adjacent grinding ridges 31.

[0036] Furthermore, the bottom inner wall of the extrusion filter chamber 2 is provided with a stepped surface. The bottom of the hopper 3 is engaged with the stepped surface to form a connection with the extrusion filter chamber 2. The outer peripheral wall of the bottom of the hopper 3 is provided with a protrusion 32. The protrusion 32 extends in the circumferential direction. There are two or more protrusions 32, which are distributed circumferentially on the outer peripheral wall of the hopper 3. The inner peripheral wall of the top of the extrusion filter chamber 2 is provided with a groove 33. The groove 33 is provided in a one-to-one correspondence with the protrusion 32. The direction of the groove 33 is connected to the protrusion 32. An inlet 34 is opened on the side of the groove 33. After the protrusion 32 enters from the inlet 34, it continues to slide into the groove 33 by rotating the hopper 3. This makes the protrusion 32 and the groove 33 form an axial limit, preventing the hopper 3 from axially separating from the extrusion filter chamber 2.

[0037] Furthermore, the outer peripheral surface of the protrusion 32 is provided with an axial recess 35, and the groove 33 is provided with a protrusion 36 that is adapted to the recess 35. When the protrusion 32 slides into the groove 33, the protrusion 36 and the recess 35 interlock to form a radial limit, preventing the protrusion 32 from detaching from the groove 33.

[0038] This utility model is not limited to the above-described preferred embodiments. Anyone can derive other forms of products under the guidance of this utility model. However, regardless of any changes made in their shape or structure, any technical solution that is the same as or similar to this application falls within the protection scope of this utility model.
