Description

Technical Field

[0001] This application relates to the field of food processing equipment technology, and in particular to a juicer. Background Technology

[0002] A slow juicer is a juicing device that works on the principle of low-speed spiral extrusion. Unlike high-speed cutting juicing structures, it slowly squeezes and grinds the ingredients, effectively separating the juice from the pulp and preserving the original taste and nutrition of the ingredients to the greatest extent. It is widely used in home juicing scenarios.

[0003] In a juicer, a filter screen with densely packed small holes is installed around the screw extrusion assembly to allow juice to pass through. Large particles of residue (such as continuous fibers, seeds, etc.) are trapped inside the filter screen. In this way, juice and pulp are separated.

[0004] The problem with existing juicers is that juice and residue, especially residue, can easily enter the bottom of the spiral extrusion assembly, causing the spiral extrusion assembly to be lifted upwards. On the one hand, this causes residue to leak along the bottom center of the spiral extrusion assembly to the outside of the juicer as a whole, or even into the drive assembly. On the other hand, after the spiral extrusion assembly is lifted upwards, it further lifts and damages other structures of the juicer. Summary of the Invention

[0005] The purpose of this application is to provide a juicer that can improve the way residue enters the bottom of the spiral extrusion assembly and prevent the spiral extrusion assembly from being lifted.

[0006] This application provides a juicer, including: The main tube assembly includes a first base plate and a first side plate connected to the first base plate and forming an enclosure, with a first cavity formed between the first base plate and the first side plate.

[0007] In some embodiments, a first groove is formed between adjacent first grinding protrusions, the circumferential width of the first groove gradually increasing in a radial direction from the inside to the outside; and / or, a second groove is formed between adjacent second grinding protrusions, the circumferential width of the second groove gradually increasing in a radial direction from the inside to the outside.

[0008] In some embodiments, the first grinding protrusion has the same circumferential width at all radial locations; and / or, the second grinding protrusion has the same circumferential width at all radial locations.

[0009] In some embodiments, the first grinding protrusion has a first sidewall on each of its circumferential sides, and the first sidewall is a plane parallel to the first axis. And / or, the second grinding protrusion has a second sidewall on each of its circumferential sides, the second sidewall being a plane parallel to the first axis.

[0010] In some embodiments, in each of the first abrasive protrusions, the two first sidewalls are parallel to each other; and / or, in each of the second abrasive protrusions, the two second sidewalls are parallel to each other.

[0011] In some embodiments, the perpendicular line from any point on the radially inner side of the first sidewall to the first axis is defined as the first perpendicular line, and the angle between the first perpendicular line and the first sidewall is 30° to 60°. And / or, let the perpendicular line from any point on the radially inner side of the second sidewall to the first axis be the second perpendicular line, and the angle between the second perpendicular line and the second sidewall be 30°~60°.

[0012] In some embodiments, the number of the first grinding protrusions is equal to the number of the second grinding protrusions; and / or, the circumferential width of the first grinding protrusion is equal to the circumferential width of the second grinding protrusion.

[0013] In some embodiments, the bottom wall of the first groove is inclined gradually away from the second abutment surface in a radial direction from the inside to the outside; and / or, the bottom wall of the second groove is inclined gradually away from the first abutment surface in a radial direction from the inside to the outside.

[0014] In some embodiments, the second base plate is provided with a second through hole extending along the first axis, and the second abutment surface is provided with a second boss protruding from the periphery of the second through hole; The first abutment surface is provided with a first clearance groove, and along the direction of the first axis, the second boss is at least partially located within the first clearance groove; The second grinding protrusion is located on the outside of the second protrusion.

[0015] In some embodiments, the second abutment surface is further provided with a third protrusion, the third protrusion being located outside the second protrusion, and the height of the third protrusion being less than the height of the second protrusion; The first contact surface is provided with a second clearance groove, which is located around the first clearance groove; along the direction of the first axis, the third boss is at least partially located in the second clearance groove, and the second grinding protrusion is provided on the surface of the third boss facing the spiral extrusion assembly.

Along the rotation direction of the spiral extrusion assembly, the first grinding protrusions are gradually inclined from the outside inwards. And / or, the second abutment surface has a plurality of second grinding protrusions spaced apart along the first axis. This allows the second grinding protrusions to gradually incline from the inside outwards along the rotation direction of the spiral extrusion assembly. When the spiral extrusion assembly rotates relative to the filter assembly, the arrangement of the first and / or second grinding protrusions can push the residue radially outwards, preventing residue from entering or even accumulating between the first and second abutment surfaces, avoiding lifting of the spiral extrusion assembly, and thus preventing damage to the spiral extrusion assembly and other components of the juicer.

[0023] To illustrate the technical solutions described in this application, the following detailed description is provided in conjunction with specific drawings and embodiments.

[0024] like Figure 1 , Figure 2 and Figure 3 As shown, this application embodiment provides a juicer 100, which includes a main cylinder assembly 30, a filter assembly 40, and a screw extrusion assembly 50. Figure 2 , Figure 3 and Figure 4 As shown, the main tube assembly 30 has a first cavity 310. (As indicated...) Figure 4 and Figure 13 As shown, the filter assembly 40 is disposed within the first cavity 310. Figure 9 and Figure 10 As shown, the filter assembly 40 includes a second base plate 41 and a second side plate 42. The second side plate 42 is connected to one side surface of the second base plate 41 and is enclosed. That is, the second side plate 42 and the second base plate 41 generally define a cavity with one end open.

[0025] It should be noted that the second side plate 42 of the filter assembly 40 is used to provide filtration. The second base plate 41 is fixedly connected to the main cylinder assembly 30 so that the filter assembly 40 is fixedly installed within the first cavity 310 of the main cylinder assembly 30. Figure 4 As shown, the spiral extrusion assembly 50 is located on the inner side of the second side plate 42 and is rotatably connected to the second base plate 41 around the first axis X.

[0026] There is a certain gap between the outer peripheral surface of the spiral extrusion assembly 50 and the inner peripheral surface of the filter assembly 40. This gap serves as the grinding space 10. Figure 4 and Figure 13 As shown. The ingredients are ground within the grinding space 10 as the screw extrusion assembly 50 rotates, until juice and residue are formed. During the rotation of the screw extrusion assembly 50, the juice flows outward through the second side plate 42 of the filter assembly 40, while the residue remains inside the second side plate 42.

[0027] It should be noted that under normal operating conditions, the juicer 100 has a fixed orientation, and the juicer 100 is positioned on a horizontal or near-horizontal plane. This will be illustrated using an example where the first axis X is parallel to the vertical direction. The spiral extrusion assembly 50 is located on the upper side of the second base plate 41.

[0028] The first axis X can also serve as the central axis of the juicer 100 as a whole.

[0029] like Figure 5 and Figure 6 As shown, in an embodiment of this application, the spiral extrusion assembly 50 has a first abutment surface 56 facing the second base plate 41. The first abutment surface 56 may be at least a portion of the end face of the spiral extrusion assembly 50 facing the second base plate 41. Figure 9 and Figure 10 As shown, the second base plate 41 has a second abutment surface 411 facing the spiral extrusion assembly 50. The second abutment surface 411 may be at least a portion of the surface of the second base plate 41 facing the spiral extrusion assembly 50.

[0030] Among them, such as Figure 5 , Figure 6 and Figure 7 As shown, the first abutment surface 56 has a plurality of first abrasive ridges 561 spaced apart along the first axis X, in the rotation direction of the spiral extrusion assembly 50 (exemplary, see [link]). Figure 6 As shown, facing the first abutment surface 56, the spiral extrusion assembly 50 rotates counterclockwise around the first axis X, and the first grinding protrusion 561 is gradually inclined from the outside to the inside; and / or, as Figure 9 and Figure 10 As shown, the second abutment surface 411 has a plurality of second grinding protrusions 4111 spaced apart around the first axis X, along the rotation direction of the spiral extrusion assembly 50 (exemplarily, such as...). Figure 9 As shown, facing the second abutment surface 411, the spiral extrusion assembly 50 will rotate clockwise on the second abutment surface 411, and the second grinding protrusion 4111 is gradually inclined from the inside to the outside.

[0031] like Figure 6 and Figure 7 As shown, the first grinding protrusion 561 has first sidewalls 563 on both sides along its circumferential direction. The first sidewalls 563 are arranged radially inclined relative to the spiral extrusion assembly 50. Figure 6 As shown, if residue enters between the first contact surface 56 and the second contact surface 411, as the screw extrusion assembly 50 rotates, the residue experiences a tangential force F from the first grinding protrusion 561. This force F can be decomposed into a first component F1 along the first sidewall 563 and a second component F2 perpendicular to the first sidewall 563. The first component F1 causes the residue to move outward along the first sidewall 563, while the second component F2 causes the residue to rest against the first sidewall 563 and experience friction as it moves outward along the first sidewall 563 (this friction is negligible in actual use). Therefore, the force F generally causes the residue to move outward along the first sidewall 563 without moving inward.

[0032] like Figure 9 As shown, the second grinding protrusion 4111 has second sidewalls 4113 on both circumferential sides. The second sidewalls 4113 are inclined relative to the radial direction of the spiral extrusion assembly 50. Figure 9As shown, if residue enters between the first contact surface 56 and the second contact surface 411, as the screw extrusion assembly 50 rotates, the residue experiences a tangential force F' from the second grinding protrusion 4111. This force F' can be decomposed into a first component F1' along the second sidewall 4113 and a second component F2' perpendicular to the second sidewall 4113. The first component F1' causes the residue to move outward along the second sidewall 4113, while the second component F2' causes the residue to rest against the second sidewall 4113 and experience frictional force (which is negligible) as it moves outward along the second sidewall 4113. Therefore, the force F' generally causes the residue to move outward along the second sidewall 4113 without moving inward.

[0033] When residue enters between the first contact surface 56 and the second contact surface 411, as the screw extrusion assembly 50 and the filter assembly 40 rotate relative to each other, the first grinding protrusion 561 can gradually push the residue outward until it reaches the edge of the screw extrusion assembly 50, and the second grinding protrusion 4111 can also gradually push the residue outward until it reaches the edge of the screw extrusion assembly 50. Therefore, the arrangement of the first grinding protrusion 561 and / or the second grinding protrusion 4111 can push the residue in a radially outward direction, preventing the residue from entering or even accumulating between the first contact surface 56 and the second contact surface 411, preventing the screw extrusion assembly 50 from being lifted, and thus preventing damage to the screw extrusion assembly 50 and other parts of the juicer 100.

[0034] Radial refers to multiple directions perpendicular to the first axis X. Circumferential refers to directions surrounding the first axis X.

[0035] like Figure 4 As shown, the main cylinder assembly 30 includes a first base plate 31 and a first side plate 32. The first side plate 32 is connected to one side surface of the first base plate 31 and is enclosed, forming a first cavity 310 between the first base plate 31 and the first side plate 32. That is, the first base plate 31 and the first side plate 32 substantially define a cavity open at one end. The filter assembly 40 is disposed within the first cavity 310.

[0036] In some embodiments of this application, the second base plate 41 may be omitted from the filter assembly 40. In this case, the second abutment surface 411 is the side surface of the first base plate 31 facing the spiral extrusion assembly 50 in the direction along the first axis X. In this case, the second side plate 42 of the filter assembly 40 surrounds the spiral extrusion assembly 50 and each of the second abrasive protrusions 4111.

[0037] That is, the second grinding protrusion 4111 can be disposed on the first base plate 31 or the second base plate 41, as long as it is opposite to the spiral extrusion assembly 50 along the first axis X. In the embodiments and drawings of this application, the second grinding protrusion 4111 is disposed on the second base plate 41 as an example.

[0038] In some embodiments of this application, the spiral extrusion assembly 50 is provided with a first grinding protrusion 561 and the second base plate 41 is provided with a second grinding protrusion 4111.

[0039] Of the two first sidewalls 563 of the first grinding protrusion 561, during the rotation of the spiral extrusion assembly 50, one of the first sidewalls 563 is directly facing the residue in the circumferential direction. This first sidewall 563 is the first sidewall 563 located on the front side in the rotation direction of the spiral extrusion assembly 50, and the other is the first sidewall 563 located on the rear side.

[0040] In the rotation of the spiral extrusion assembly 50, one of the two second sidewalls 4113 of the second grinding protrusion 4111 is directly facing the residue in the circumferential direction. This second sidewall 4113 is the second sidewall 4113 located on the front side in the rotation direction of the spiral extrusion assembly 50, and the other is the second sidewall 4113 located on the rear side.

[0041] Any first sidewall 563 can be a plane, specifically a plane parallel to the first axis X (in the top view, the first sidewall 563 is a straight line), or a curved surface, specifically a curved surface that bends towards the first axis X (in the top view, the first sidewall 563 is a curve). Any second sidewall 4113 can be a plane, specifically a plane parallel to the first axis X (in the top view, the second sidewall 4113 is a straight line), or a curved surface, specifically a curved surface that bends towards the first axis X (in the top view, the second sidewall 4113 is a curve).

[0042] In some alternative embodiments, at least the first sidewall 563 located on the front side is planar. In some alternative embodiments, at least the second sidewall 4113 located on the front side is planar. The purpose of this arrangement is to facilitate the processing and fabrication of the first sidewall 563. On the other hand, the residue experiences the same stress at all points on the first sidewall 563 and the same stress at all points on the second sidewall 4113. By setting a suitable and optimal inclination angle for the first sidewall 563 and the second sidewall 4113, the residue can be pushed outward as quickly as possible.

[0043] like Figure 6 , Figure 7 , Figure 9 and Figure 11As shown, both first sidewalls 563 of the first grinding protrusion 561 are flat. Both second sidewalls 4113 of the second grinding protrusion 4111 are also flat. This is beneficial for the processing of the first grinding protrusion 561 and the second grinding protrusion 4111.

[0044] The filter assembly 40 is disposed on the upper side of the first base plate 31 and is fixedly connected to the upper surface of the first base plate 31. The fixed connection here means that under the normal working condition of the juicer 100, the filter assembly 40 can neither rotate relative to the first base plate 31 around the first axis X, nor leave the first base plate 31 along the first axis X. That is, the filter assembly 40 and the main cylinder assembly 30 remain relatively stationary.

[0045] The filter assembly 40 is detachably mounted on the first base plate 31. When the juicer 100 is not in operation, the filter assembly 40 can be removed from the main cylinder assembly 30 so that the user can clean, repair or replace the main cylinder assembly 30 and the filter assembly 40 respectively.

[0046] In some embodiments of this application, such as Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, the juicer 100 also includes a base 20, which includes a bottom shell 21 and a drive assembly 22 disposed on the bottom shell 21. A first base plate 31 has a first through hole (not shown) extending along the first axis X direction. Figure 9 and Figure 10 As shown, the second base plate 41 has a second through hole 43 extending along the first axis X direction. The spiral extrusion assembly 50 is connected to the drive assembly 22 via the first through hole and the second through hole 43. When the second grinding protrusion 4111 is provided on the first base plate 31, the second grinding protrusion 4111 is arranged around the first through hole.

[0047] In some embodiments, such as Figure 13 As shown, the orthographic projection of the second through hole 43 on the horizontal plane lies within the orthographic projection of the lower end face of the screw extrusion assembly 50 on the horizontal plane. In some embodiments, the portion of the screw extrusion assembly 50 and the drive assembly 22 passing through the first through hole and the second through hole 43 is sealed and rotatably disposed in the first through hole and the second through hole 43, that is, it maintains a dynamic seal with the first through hole and the second through hole 43. The purpose of this arrangement is to allow the drive assembly 22 to connect and drive the screw extrusion assembly 50 to rotate, while preventing residue, juice, etc. from leaking from the second through hole 43 and from the first through hole.

[0048] like Figure 4 As shown, in some embodiments of this application, the drive assembly 22 includes a drive body 221 and a drive shaft 222 connected to each other. For example... Figure 4As shown, the drive body 221 is disposed inside the base shell 21, and the drive shaft 222 is disposed on the upper side of the base shell 21. That is, in this base 20, the drive shaft 222 protrudes from the upper side of the base shell 21. Optionally, as... Figure 5 and Figure 6 As shown, the spiral extrusion assembly 50 has a shaft hole 51 on its lower end face. The shaft hole 51 has the same shape as the drive shaft 222, so that the spiral extrusion assembly 50 and the drive shaft 222 form a circumferential fixed connection. For example, the drive shaft 222 can be a D-shaped shaft, an H-shaped shaft, etc., and the shaft hole 51 has a similar shape accordingly.

[0049] like Figure 4 As shown, in some embodiments of this application, a connecting shaft 55 may be fixedly provided within the shaft hole 51 of the spiral extrusion assembly 50. Alternatively, the connecting shaft 55 may be included on the side of the spiral extrusion assembly 50 facing the second base plate 41. Figure 4 As shown, the connecting shaft 55 and the drive shaft 222 are detachably connected in the direction along the first axis X, and fixedly connected in the circumferential direction. Optionally, as shown... Figure 4 As shown, the drive shaft 222 can be inserted into the connecting shaft 55.

[0050] In other alternative embodiments, the connecting shaft 55 can pass downwards through the second through hole 43 and the first through hole and then enter the bottom shell 21 to connect with the drive assembly 22, or extend into the bottom shell 21 and connect with the drive body 221. Alternatively, the drive shaft 222 can be located on the upper side of the bottom shell 21 and extend into the main cylinder assembly 30 and be inserted into the connecting shaft 55.

[0051] In this application, the example of a connecting shaft 55 rotatably and sealingly disposed within both the first through hole and the second through hole 43 will be used for further description. In some embodiments of this application, such as Figure 13 As shown, the first base plate 31 has a first boss 36, and a first through hole penetrates the first boss 36. The first boss 36 is formed by extending upward from the upper surface of the first base plate 31. Figure 5 and Figure 6 As shown, the lower end face of the spiral extrusion assembly 50 is provided with a first clearance groove 52. The first clearance groove 52 is formed by an upward indentation from the lower end face of the spiral extrusion assembly 50. Figure 13 As shown, along the first axis X, the first boss 36 is at least partially located within the first relief groove 52. The second base plate 41 is disposed around the periphery of the first boss 36. In other words, the first boss 36 actually passes through the second through hole 43. Along the first axis X, the thickness of the second base plate 41 is less than the height of the first boss 36. The purpose of this arrangement is to elevate the position of the first through hole through the design of the first boss 36, so that juices, residues, etc., within the grinding space 10 are at a lower position and less likely to leak from the first through hole.

[0052] The shaft hole 51 can be coaxially arranged with the first clearance groove 52. Alternatively, the shaft hole 51 can be formed inside the first clearance groove 52. In the direction along the first axis X, the depth of the shaft hole 51 can be greater, and the depth of the first clearance groove 52 can be relatively smaller.

[0053] In some embodiments of this application, such as Figure 9 , Figure 10 and Figure 13 As shown, the second abutment surface 411 has a second protrusion 44 protruding from the periphery of the second through hole 43, and the second protrusion 44 is located outside the first protrusion 36. Figure 6 and Figure 7 As shown, the first contact surface 56 of the spiral extrusion assembly 50 is provided with a first relief groove 52 recessed upward along the first axis X. Along the direction of the first axis X, the second boss 44 is at least partially located within the first relief groove 52. By providing the second boss 44, juice, residue, etc., can be further confined to a position outside and below the second through hole 43, preventing juice, residue, etc. from leaking from the second through hole 43.

[0054] In some embodiments of this application, such as Figure 9 , Figure 10 and Figure 13 As shown, the second abutment surface 411 is also provided with a third protrusion 45, which is located outside the second protrusion 44, and the height of the third protrusion 45 is less than the height of the second protrusion 44. The second grinding protrusion 4111 is provided on the surface of the third protrusion 45.

[0055] In some embodiments of this application, such as Figure 5 , Figure 6 and Figure 13 As shown, the first abutment surface 56 is provided with a second clearance groove 53, which is located around the first clearance groove 52; along the direction of the first axis X, the third boss 45 is at least partially located inside the second clearance groove 53. The first grinding protrusion 561 is provided on the axial bottom wall of the second clearance groove 53.

[0056] It is understandable that when the filter assembly 40 does not include the second base plate 41, the first base plate 31 can be provided with the first boss 36 and the third boss 45, which can still cooperate with the first clearance groove 52 and the second clearance groove 53 of the spiral extrusion assembly 50.

[0057] In some embodiments of this application, such as Figure 6 , Figure 7 and Figure 8 As shown, a first groove 562 is formed between adjacent first grinding protrusions 561, and the circumferential width of the first groove 562 gradually increases in the radial direction from the inside to the outside.

[0058] The purpose of this design is to ensure that the circumferential width of the radially outer end of the first groove 562 is greater, meaning that the radially outer portion of the first groove 562 can accommodate more residue. Therefore, the residue pushed outward can be fully dispersed within the first groove 562. In other words, even if there is some residue within the first groove 562, the residue will maintain a relatively small thickness (dimension along the first axis X), and as it continues to move outward, the residue layer can become thinner without accumulating.

[0059] In some embodiments of this application, such as Figure 6 , Figure 7 and Figure 8 As shown, the circumferential width of the first grinding protrusion 561 is equal at all radial points. That is, the two first sidewalls 563 are parallel to each other. This arrangement facilitates the manufacturing of the first grinding protrusion 561 and ensures sufficient width and strength at all points, preventing breakage. It also provides sufficient circumferential width for the first groove 562. In other embodiments, the circumferential width of the first grinding protrusion 561 can gradually increase in the radially outward direction, as long as it does not significantly encroach on the circumferential width of the first groove 562 or cause the circumferential width of the first groove 562 to gradually decrease.

[0060] like Figure 6 As shown in the top view, each of the first grinding protrusions 561 is rotationally symmetrically distributed around the center point D (located on the first axis X). The number of the first grinding protrusions 561 is unlimited and can be set according to the specific outer diameter range of the spiral extrusion assembly 50, as long as a sufficient number of first grinding protrusions 561 and their first grooves 562 can be divided to meet the requirement of pushing the residue outward, while not making the spiral extrusion assembly 50 difficult to process.

[0061] The degree of inclination of the first sidewall 563 (especially the first sidewall 563 located on the front side) can affect its effect on pushing the residue outward. For example Figure 6 As shown in the top view, point E is the side of the first sidewall 563 (taking the front side as an example) closest to the center point D. Point E can be any point on the side of the first sidewall 563 closest to the center point D. A line DE can be formed between the center point D and point E. This line DE can be a perpendicular line from any point on the radially inner side of the first sidewall 563 to the first axis X, defined as the first perpendicular line. The angle between this line DE and the first sidewall 563 is α, where α is 30° to 60°. Within this range, it facilitates the smooth outward movement of the residue. In some embodiments, α is 40° to 60°. In some embodiments, α is 45° to 60°. In some embodiments, α is 50° to 60°.

[0062] In some specific embodiments of this application, α is 30°, 31°, 32°, 33°, 34°, 35°, 36°, 37°, 38°, 39°, 40°, 41°, 42°, 43°, 44°, 45°, 46°, 47°, 48°, 49°, 50°, 51°, 52°, 53°, 54°, 55°, 56°, 57°, 58°, 59°, or 60°.

[0063] In some embodiments of this application, such as Figure 8 As shown, the bottom wall of the first groove 562 gradually slopes away from the second abutment surface 411 in the radial direction from the inside to the outside, that is, it gradually slopes upward in the radial direction from the inside to the outside. This causes the space height between the spiral extrusion assembly 50 and the second abutment surface 411 in the first groove 562 to gradually decrease in the radial direction from the inside. Similarly, the residue pushed outward can be fully dispersed in the first groove 562. This facilitates the outward pushing of residue and also avoids residue accumulation.

[0064] In some embodiments of this application, such as Figure 9 , Figure 10 and Figure 11 As shown, a second groove 4112 is formed between adjacent second grinding protrusions 4111, and the circumferential width of the second groove 4112 gradually increases in the radial direction from the inside to the outside. The purpose of this arrangement is that the circumferential width of the radially outer end of the second groove 4112 is larger, meaning that the radially outer portion of the second groove 4112 can accommodate more residue. Therefore, the residue pushed outward can be sufficiently dispersed within the second groove 4112. That is, even if there is some residue within the second groove 4112, the residue will maintain a small thickness (the dimension along the first axis X), and as it continues to move outward, the residue layer can become thinner without forming an accumulation.

[0065] In some embodiments of this application, such as Figure 9 , Figure 10 As shown, the circumferential width of the second grinding protrusion 4111 is equal at all radial points. That is, the two second sidewalls 4113 are parallel to each other. This arrangement facilitates the manufacturing of the second grinding protrusion 4111 and ensures sufficient width and strength at all points, preventing breakage. It also provides sufficient circumferential width for the second groove 4112. In other embodiments, the circumferential width of the second grinding protrusion 4111 can gradually increase in the radially outward direction, as long as it does not significantly encroach on the circumferential width of the second groove 4112 or cause the circumferential width of the second groove 4112 to gradually decrease.

[0066] like Figure 9 As shown in the top view, each of the second grinding protrusions 4111 is rotationally symmetrical about the center point D. The number of the second grinding protrusions 4111 is not limited and can be set according to the specific outer diameter range of the spiral extrusion assembly 50, as long as a sufficient number of second grinding protrusions 4111 and their second grooves 4112 can be divided to meet the requirement of pushing the residue outward, while not making the spiral extrusion assembly 50 difficult to process.

[0067] The inclination of the second sidewall 4113 (especially the second sidewall 4113 located on the front side) can affect its effect on pushing the residue outward. For example Figure 9 As shown in the top view, the end of the second sidewall 4113 (taking the front side sidewall 4113 as an example) closest to the center point D is point F, and a line DF can be formed between the center point D and point F. This line DF can be a perpendicular line from any point on the radially inner side of the second sidewall 4113 to the first axis X, defined as the second perpendicular line. The angle between this line DF and the second sidewall 4113 is β, where β is 30°~60°. Within this range, it is beneficial for the residue to be smoothly pushed outward. In some embodiments, β is 40°~60°. In some embodiments, β is 45°~60°. In some embodiments, β is 50°~60°.

[0068] In some specific embodiments of this application, β is 30°, 31°, 32°, 33°, 34°, 35°, 36°, 37°, 38°, 39°, 40°, 41°, 42°, 43°, 44°, 45°, 46°, 47°, 48°, 49°, 50°, 51°, 52°, 53°, 54°, 55°, 56°, 57°, 58°, 59°, or 60°.

[0069] In some embodiments of this application, such as Figure 12 As shown, the bottom wall of the second groove 4112 gradually slopes away from the first abutment surface 56 in the radial direction from the inside to the outside, that is, it gradually slopes downward in the radial direction from the inside to the outside. This causes the space height between the spiral extrusion assembly 50 and the second abutment surface 411 in the second groove 4112 to gradually decrease in the radial direction from the inside. Similarly, the residue pushed outward can be fully dispersed in the second groove 4112. This facilitates the outward pushing of residue and also avoids residue accumulation.

[0070] In some embodiments of this application, the number of first grinding protrusions 561 is equal to the number of second grinding protrusions 4111. This arrangement aims to ensure that, during the rotation of the spiral extrusion assembly 50, the first grinding protrusions 561 and the second grinding protrusions 4111 can form a periodic alignment (aligned along the first axis X direction), and the first groove 562 and the second groove 4112 can form a periodic alignment. This allows for the periodic and regular outward pushing of residue, ensuring that residue at different circumferential positions is pushed out and preventing excessive residue in any particular area.

[0071] In some embodiments of this application, the circumferential width of the first grinding protrusion 561 is equal to the circumferential width of the second grinding protrusion 4111. The first grinding protrusion 561 and the second grinding protrusion 4111 can be periodically and completely aligned so that the first groove 562 and the second groove 4112 can be completely aligned along the first axis X direction, thereby allowing as much residue as possible to fall into the second groove 4112 and be pushed forward by the first grinding protrusion 561.

[0072] In some embodiments of this application, such as Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, the juicer 100 also includes a secondary cylinder assembly 60, which includes a first cylinder 61 and a second cylinder 62. Figure 4 As shown, the first cylindrical body 61 contains a second cavity 610, and the second cylindrical body 62 contains a third cavity 620. The first cylindrical body 61 is located along the first axis X on the side of the main cylindrical assembly 30 opposite to the base 20, and the second cylindrical body 62 is located on the side of the first cylindrical body 61 opposite to the base 20. The second cylindrical body 62 is offset from the first axis X. The second cylindrical body 62 has a dispensing port.

[0073] like Figure 4 and Figure 5 As shown, the spiral extrusion assembly 50 is provided with spiral blades 54. The spiral extrusion assembly 50 has a centrally rotating structure.

[0074] like Figure 4As shown, the height of the spiral extrusion assembly 50 along the first axis X is greater than the depth of the first cavity 310, such that a portion (the upper part) of the spiral extrusion assembly 50 is located within the second cavity 610 and is generally coaxial with the second cavity 610. At this time, an annular space is formed between the inner circumferential surface of the second cavity 610 and the outer circumferential surface of the spiral extrusion assembly 50, and this space is defined as the extrusion space 11. Along the first axis X, this extrusion space 11 communicates with the aforementioned grinding space 10. Within this extrusion space 11, the blades 54 perform preliminary extrusion and crushing of large, blocky food ingredients. The bottom (lower opening) of the third cavity 620 of the second cylinder 62 is not precisely aligned with the uppermost (center) end of the spiral extrusion assembly 50, but can be aligned with the spiral blades 54. Therefore, blocky food ingredients, etc., fed into the second cylinder 62 through the feeding port can fall directly onto the upper surface of the blades 54 and be directly extruded. This prevents chunks of food from splashing inside the second cavity 610.

[0075] like Figure 4 As shown, due to the relative misalignment between the second cylinder 62 and the first cylinder 61, the first cylinder 61 has an upper inner bottom wall. Figure 4 As shown, the upper end of the spiral extrusion assembly 50 abuts against the upper inner bottom wall of the first cylinder 61. Thus, in the direction along the first axis X, the spiral extrusion assembly 50 is constrained between the upper inner bottom wall of the first cylinder 61 and the second bottom plate 41.

[0076] By maintaining a fixed connection between the first cylinder 61 and the main cylinder assembly 30 in the direction along the first axis X, the screw extrusion assembly 50 can also be fixed in the direction along the first axis X. In this case, the screw extrusion assembly 50 does not need to rely on any other means to form a connection with the second base plate 41 in the direction along the first axis X. Furthermore, the filter assembly 40 also does not need to rely on any other means to form a connection with the first base plate 31 in the direction along the first axis X.

[0077] In some embodiments, the first cylindrical body 61 and the second cylindrical body 62 can be integrally formed.

[0078] In some embodiments of this application, the upper side of the second cylinder 62 is an open design to form the aforementioned dispensing port. On the juicer 100, this dispensing port can be an open design. Or, as... Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, in some optional embodiments of this application, the juicer 100 further includes an upper cover 70, which is disposed at the upper opening of the second cylinder 62 and is used to open and close the dispensing port. Optionally, as shown... Figure 2As shown, the upper cover 70 is rotatably connected to the upper end of the second cylinder 62 about the second axis Y. The second axis Y can be substantially perpendicular to or perpendicular to the first axis X.

[0079] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this application should be included within the protection scope of this application.
