Description

Technical Field

[0001] The utility model relates to the field of food processing, in particular to an extrusion type juicer which realizes juice extraction by screw extrusion. Background Art

[0002] The existing slow-speed extrusion juicer uses screw extrusion to separate the juice and pomace of the ingredients. It relies on the low speed of the screw to reduce the contact between the juice and oxygen, and does not heat the juice to avoid oxidation of the juice, thereby improving the processed taste of the juice. The structure of the existing juicer to separate the juice from the pomace is usually a filter or filter bar. The filter structure is easily blocked by pomace during juice discharge, affecting the normal juice discharge, and the juice discharge efficiency is low and affects the juice discharge rate of the ingredients. The technical solution using the filter structure is gradually weakened and eliminated.

[0003] In the existing bar-type juice outlet structure, a juice outlet channel for juice outlet is formed between the bars. In order to improve the taste of the juice and prevent the pomace from flowing out of the juice outlet channel, the gap between the bars needs to be set as small as possible. However, such a setting has the following technical problems: on the one hand, the bars need to be separated from each other to form a juice outlet channel, and on the other hand, the gap is expected to be as small as possible, which causes a contradiction between the bars and the gap, and the existing bars cannot effectively solve such a contradiction. In addition, the existing bars will be deformed by the extrusion of the screw during operation. Such deformation will enable more juice to be quickly discharged from the enlarged gap, but it will also cause the problem of pomace being discharged from the gap together; if the strength of the bars is increased and the deformation of the bars is reduced, the bars will promote the function of adaptive adjustment. The main reason for this is that there is still a contradiction that the juice outlet gap composed of the bars depends on the extrusion deformation of the screw and prevents excessive deformation during extrusion. Even if excessive deformation does not occur at a single time, material fatigue will occur after long-term use, resulting in excessive deformation. In other words, for the existing bar structure, such technical problems cannot be completely avoided. Utility Model Content

[0004] The utility model aims to provide an extrusion type juice machine with pure juice, better taste, no influence from extrusion and stable and reliable structure.

[0005] The utility model provides an extruding juicer with fast juice output, comprising a main unit with a motor, a juice collecting chamber arranged on the main unit, a detachable extruding assembly arranged in the juice collecting chamber, and a feeding cover covering the juice collecting chamber, the extruding assembly comprising a screw and a juice squeezing barrel sleeved outside the screw, the inner wall of the juice collecting chamber is provided with positioning ribs, the juice squeezing barrel is inserted into the positioning ribs and fixedly matched with the juice collecting chamber, the juice squeezing barrel comprises a barrel body and an extruding sheet, the extruding sheet is located at the lower end of the barrel body and is axially rotatable, the extruding sheets are multiple and arranged circumferentially, and the extruding sheets overlap and adhere to each other under the push of the screw to form a juice output gap between adjacent extruding sheets. The present application provides a squeeze sheet in the juice squeezer. When the squeeze sheet is subjected to the squeeze force of the screw, the squeeze sheets arranged circumferentially overlap and fit each other. At this time, the squeeze sheet located radially inside fits with the adjacent squeeze sheet located outside to form a juice outlet gap. Since the juice outlet gap is not located between the adjacent circumferentially arranged bars, the squeeze sheet will not be affected when subjected to the squeeze force. Even if the squeeze sheet is squeezed outward, the juice outlet gap will not be excessively expanded. In fact, the squeeze sheet located on the inside will fit more tightly with the adjacent squeeze sheet when squeezed, making the juice outlet gap smaller and further improving the pure taste of the juice. Further, positioning ribs are provided on the bottom wall of the juice collecting chamber, and the juice squeezer is directly inserted into the positioning ribs to achieve fixed fit. In this way, the squeeze sheet can be limited at the bottom end by means of the positioning ribs, which can prevent the bottom end of the squeeze sheet from being excessively deformed outward when squeezed by the screw when it is suspended in the air, thereby effectively protecting the squeeze sheet.

[0006] Preferably, filter ribs are provided at the positions where the squeezed sheets and adjacent squeezed sheets are fitted, and the filter ribs fit the adjacent squeezed sheets and form juice outlet gaps between the filter ribs. Further, filter ribs are provided on the squeezed sheets to form juice outlet gaps between the filter ribs, which can avoid the problem of too small gaps when the squeezed sheets fit together, or even the problem of two squeezed sheets fitting together completely without forming juice outlet gaps, thereby increasing juice outlet efficiency.

[0007] Preferably, the inner side wall of the extrusion sheet opposite to the fitting position is provided with an extrusion rib, and the extrusion rib protrudes toward the center of the juice squeezing barrel. The extrusion ribs are provided on the fixed extrusion sheet and the inner side wall of the extrusion sheet. On the one hand, the extrusion ribs are used to reduce the gap between the juice squeezing barrel and the screw, so that the screw grinds and crushes the food more thoroughly; on the other hand, the extrusion ribs realize the cutting function, which also makes the cutting and crushing of the food more thorough, so that the juicer has a higher juice yield.

[0008] Preferably, the juice squeezer also includes a fixing ring located at the lower end of the squeeze sheet, and the fixing ring is inserted into the positioning rib. A fixing ring is further provided, and the bottom end of the squeeze sheet is fixedly connected by the fixing ring, so that the juice squeezer itself can also fix and limit the bottom end of the squeeze sheet, thereby preventing the end of the squeeze sheet from being squeezed by the screw and deformed when it is suspended in the air, thereby improving the overall strength of the juice squeezer and ensuring that the structure of the juice squeezer is stable and reliable.

[0009] Preferably, the juice collecting chamber is provided with a residue outlet connected to the inner ring of the positioning rib, a juice outlet connected to the outer ring of the positioning rib, the juice outlet gap is connected to the juice outlet, and the fixed ring is further provided with a residue outlet groove connected to the residue outlet. When the residue outlet connected to the inner ring of the positioning rib is provided, the bottom end of the juice squeezing cylinder is directly inserted into the positioning rib, and the screw is further provided in the juice squeezing cylinder, so that the pomace pushed by the screw can gradually flow from top to bottom to the inside of the positioning rib, and further be discharged from the residue outlet, so that the residue discharge is efficient, and the pomace is reduced from mixing into the juice when it runs too much in the juice collecting chamber; after the juice is filtered out from the juice outlet gap, a juice outlet connected to the outer ring of the positioning rib is provided to ensure that the squeezed juice can be directly and quickly discharged from the juice outlet, thereby improving the efficiency of juice discharge.

[0010] Preferably, the slag outlet is also provided with a slag blocking module for blocking the slag outlet, and the slag blocking module includes a slag blocking sheet and an adjusting member. The slag blocking sheet is located outside the slag outlet and deforms when an external force is applied to open the slag outlet, and the adjusting member can drive the slag blocking sheet to move to change the distance between the slag blocking sheet and the outer wall of the slag outlet. A slag blocking module is further provided at the slag outlet, and the slag blocking sheet is used to appropriately block the outside of the juice outlet, so that the extrusion pressure of the pomace in the positioning rib can be increased to achieve a higher juice extraction rate; an adjusting member is then provided, and the user can adjust the internal pressure by adjusting the adjusting member to meet different juice extraction requirements. At the same time, the provision of the adjusting member also facilitates direct manipulation of the slag blocking sheet to open the slag outlet when cleaning the juice collecting chamber, which is convenient for cleaning.

[0011] Preferably, the adjusting member is rotatably arranged on the outer side wall of the juice collecting chamber, the adjusting member includes a fixing portion and an adjusting portion, and the slag blocking piece is installed on the fixing portion. The rotatably arranged adjusting member is convenient for the user to directly operate, and by providing the fixing portion and the adjusting portion, the slag blocking piece is installed on the fixing portion to facilitate the operation of the slag blocking piece.

[0012] Preferably, the side wall of the positioning rib is provided with a plurality of juice outlet grooves corresponding to the juice outlet gap. The juice outlet grooves are provided on the side wall of the positioning rib, so that more juice produced by squeezing can be discharged, especially when the juice produced at the bottom and the juice produced by squeezing after the slag blocking module is provided are blocked by the positioning rib and cannot be discharged quickly, the slag outlet grooves can be used to discharge the juice quickly and efficiently, thereby improving the overall juice outlet rate.

[0013] Preferably, the width of the juice outlet gap is no more than 2 mm. When the juice outlet gaps are squeezed by the screw, they will fit together and reduce the gap between them. That is, when the present application is implemented, the juice outlet gap will not become larger when squeezed. The width of the juice outlet gap is set to be no more than 2 mm. While ensuring rapid juice discharge, it can also effectively prevent the residue from being discharged from the juice outlet gap. It should be noted that the width of the juice outlet gap here refers to the gap size between adjacent extrusion sheets when they are in an overlapping and fitting state, and is not the matching size when the extrusion sheets are rotated to the cleaning position to fully open the space between adjacent extrusion sheets. Of course, since the extrusion sheets will be squeezed by the screw and deformed during operation, the corresponding juice outlet gap size will also change.

[0014] Preferably, the side wall of the cylinder is also provided with auxiliary filtering holes. The auxiliary filtering holes are provided on the side wall of the cylinder, and the juice produced when the food is squeezed and crushed between the screw and the cylinder can be quickly discharged through the auxiliary filtering holes, further improving the juice extraction efficiency of the juice squeezing cylinder and ensuring rapid juice extraction.

[0037] The utility model provides a squeeze type juice machine, such as Figure 1-9As shown, the juicer includes a main unit (not shown), a juice collecting chamber 2, an extrusion assembly and a feeding cover 1. The main unit is provided with a motor (not shown). The juice collecting chamber 2 is detachably arranged on the main unit. The extrusion assembly is provided in the juice collecting chamber, and the extrusion assembly includes a screw 3 and a juice squeezing barrel 4. The juice squeezing barrel 4 is sleeved on the outside of the screw 3. The feeding cover 1 covers the upper part of the juice collecting chamber 2 to close the upper opening of the juice collecting chamber 2. Food is put into the extrusion assembly through the opening of the feeding cover 1. The screw 3 is driven to rotate by the motor to squeeze, cut and grind the food between the screw 3 and the juice squeezing barrel 4 to fully crush the food. The juice collecting chamber 2 is provided with a slag outlet 21 and a juice outlet 22. The juice is filtered by the juice squeezing barrel 4 and then collected by the juice collecting chamber 2 and discharged through the juice outlet 22. At the same time, the pomace is also collected in the juice collecting chamber 2 and discharged from the slag outlet 21. The screw 3 includes a screw shaft 32 located in the center and a thread 33 on the outer wall of the screw 3. The thread 33 and the inner wall of the juice squeezing cylinder 4 are used to cut, grind and crush the food, and the juice is further separated from the pomace by the juice squeezing cylinder.

[0038] The juice squeezer 4 comprises a barrel 41, a fixed squeeze sheet 43, a movable squeeze sheet 42 and a fixed ring 44. The barrel 41 is annular and sleeved on the outer portion of the upper end of the screw 3. The fixed squeeze sheet 43 is arranged at the lower end of the barrel 41 and extends downward along the axial direction of the juice squeezer 4. The fixed squeeze sheets 43 are arranged in a plurality and are evenly spaced along the circumference of the juice squeezer 4. A mounting groove 430 is formed between two adjacent fixed squeeze sheets 43. The movable squeeze sheets 42 are the same in number as the mounting grooves 430 and are respectively arranged in the corresponding mounting grooves 430. The movable squeeze sheets 42 can be rotatably arranged in the mounting grooves 430. The fixed ring 44 is arranged at the lower ends of the fixed squeeze sheets 43 and the movable squeeze sheets 42, and is used to fix the fixed squeeze sheets 43 and the movable squeeze sheets 42. The bottom wall of the fixed ring 44 is also provided with a limit groove 441 and a slag discharge groove 442.

[0039] like Figure 2-4As shown, the bottom wall of the juice collecting chamber 2 is provided with an annular positioning rib 23, and the bottom end of the juice squeezing tube 4 is inserted into the positioning rib 23 so that the juice squeezing tube 4 and the juice collecting chamber 2 are fixedly matched at the bottom end. The inner side of the positioning rib 23 is located at the slag discharge part and is also provided with a limiting protrusion 25. The limiting protrusion 25 cooperates with the limiting groove 441 of the fixing ring 44 to limit the juice squeezing tube 4 and prevent the juice squeezing tube 4 from rotating. The center of the bottom wall of the juice collecting chamber 2 is also provided with a central boss 26, and the central boss 26 can extend into the bottom end of the screw 3. The positioning rib 23 and the central boss 26 divide the bottom wall of the juice collecting chamber 2 into a juice discharge channel 231 located outside the positioning rib 23 and a slag discharge channel 232 located inside the positioning rib 23, wherein the juice discharge channel 231 is connected to the juice outlet 22, and the slag discharge channel 232 is connected to the slag outlet 21. The side wall of the positioning rib 23 is also provided with a juice discharge groove 24, and the juice discharge groove 24 can discharge the juice flowing out along the outer wall of the juice squeezing tube to the juice discharge part. The residue discharge groove 442 is arranged corresponding to the residue discharge port 21, so that the pomace processed and squeezed from the inside of the juice squeezing tube 4 flows from the residue discharge groove 442 to the residue discharge port 21.

[0040] The slag outlet 21 is connected to the slag outlet channel 232 through the slag outlet through hole 27. The juice collecting chamber 2 is further provided with a slag blocking module located at the juice outlet through hole 27. The slag blocking module includes a slag blocking piece 281 and an adjusting member 282. Preferably, the slag blocking piece 281 is set to be a soft material such as rubber, silicone, etc. The slag blocking piece 281 is attached to the outer wall of the slag outlet through hole 27. The slag blocking piece 281 closes the slag outlet through hole 27 in a normal state. When the pomace in the slag outlet channel 232 accumulates and the pressure increases, the pomace pushes the pomace blocking piece 281 to deform so as to open the pomace through hole 27. Thus, the pomace pressure in the juice collecting chamber 2 can be adjusted by the pomace blocking piece 281, thereby making the residual juice in the pomace less, so as to improve the juice extraction rate of the food. The slag blocking piece 281 is installed on the adjusting member 282, and the adjusting member 282 further includes a fixing portion 2821 and an adjusting portion 2822. The fixing portion 2821 is used to fix the slag blocking piece 281 and push the slag blocking piece 281 to the slag discharge through hole 27. The adjusting portion 2822 protrudes outward from the outer wall of the juice collecting chamber 2, so that the user can directly operate the slag blocking module through the adjusting portion 2822. For example, when the juice collecting chamber 2 needs to be cleaned, the slag blocking piece 281 can be operated to fully open the slag discharge through hole 27; or when the user wants to reduce the internal pressure to increase the slag discharge speed, the slag discharge through hole 27 can also be opened by the adjusting portion 2822. Preferably, the fixing portion 2821 is rotatably connected to the body of the juice collecting chamber 2, so that the user can open or close the slag discharge through hole 27 by rotating the slag blocking module. Of course, the outer side wall of the juice collecting chamber may also be provided with a receiving space for receiving the slag blocking module, so as to prevent the slag blocking module from occupying extra space and affecting the appearance of the juice collecting chamber.

[0041] like Figure 5-9 As shown, a rotating shaft 61 is provided at both ends of the movable extrusion sheet 42, an upper shaft hole 62 is provided at the upper end of the mounting groove 430 of the cylinder 41, and a lower shaft hole 63 is provided at the fixed ring 44. The rotating shaft 61 of the movable extrusion sheet 42 is respectively inserted into the upper shaft hole 62 and the lower shaft hole 63, so that the movable extrusion sheet 42 is clamped between the cylinder 41 and the fixed ring 44, and rotates along the rotating shaft 61. The movable extrusion sheet 42 is rotatably provided at the lower end of the cylinder 41, and a plurality of movable extrusion sheets 42 and fixed extrusion sheets 43 are arranged circumferentially at the lower end of the cylinder 41. When the movable extrusion sheet 42 rotates and overlaps with the fixed extrusion sheet 43, as shown in FIG. Fig.10As shown, the movable extrusion sheet 42 and the fixed extrusion sheet 43 form a ring and are sleeved on the lower end of the screw 3, and a juice outlet gap 5 is formed between the movable extrusion sheet 42 and the fixed extrusion sheet 43 to achieve the function of filtering juice. When the juice cylinder 4 needs to be cleaned, the user can move the movable extrusion sheet 42 to separate the extrusion sheet from the fixed extrusion sheet 43. Fig.11 As shown, the juice outlet gap 5 is opened, so that the pomace and the like remaining in the juice outlet gap 5 can be conveniently cleaned, thereby realizing convenient cleaning of the juice squeezing cylinder.

[0042] The movable extrusion sheet 42 includes a body 421 and a fitting portion 422. The rotating shaft 61 is located at both ends of the body 421, so that the axis of the movable extrusion sheet 42 passes through the body 421. The fitting portion 422 is formed by the body 421 extending outward in the radial direction, that is, the fitting portion 422 is extended outward on the cross section of the movable extrusion sheet 42 perpendicular to the axis. When the movable extrusion sheet 42 and the fixed extrusion sheet 43 are assembled in sequence, the fitting portion 422 is located on the inner side of the fixed extrusion sheet 43. When the screw 3 is working, it pushes the material and further pushes the fitting portion 422 to rotate outward to overlap with the fixed extrusion sheet 43 and form a juice outlet gap 5 between adjacent extrusion sheets.

[0043] Preferably, when the movable extrusion sheet 42 rotates so that the fitting portion 422 overlaps and fits with the adjacent fixed extrusion sheet 43, the main body 421 and the adjacent fixed extrusion sheet 43 on the other side are also in an overlapping and fitting state, so that the movable extrusion sheet 42 and the fixed extrusion sheets 43 on both sides of the installation groove 430 form juice discharge gaps, which can improve the juice discharge efficiency. The side wall of the main body 421 and the adjacent fixed extrusion sheet 43 that fits together is also provided with support ribs 4211, and an outgoing juice groove 4212 is formed between the support ribs 4211. The outgoing juice groove 4212 and the gap between the main body 421 and the fixed extrusion sheet 43 together constitute the juice discharge gap 5. Of course, it can be understood that the movable extrusion sheet 42 can also fit with the cylinder body instead of directly fitting with the fixed extrusion sheet, but only overlaps with the fixed extrusion sheet and forms a juice discharge gap at the overlap.

[0044] Preferably, the inner side wall of the fitting portion 422 is further provided with an extrusion rib 423, which is extended along the axial direction of the juice squeezing barrel 4 and protrudes toward the center of the juice squeezing barrel 4 to be extruded and matched with the screw 3 to improve the grinding efficiency between the screw 3 and the juice squeezing barrel 4. The outer side wall of the fitting portion 422 is further provided with a filter rib 425, and when the movable squeezing sheet 42 is fitted with the fixed squeezing sheet 43, the filter rib 425 is fitted with the fixed squeezing sheet 43, and a juice outlet groove 426 is formed between the filter ribs 425, and the gap between the filter ribs 425 and the juice outlet groove 426 together constitute the juice outlet gap 5. The filter rib 425 is used to form the juice outlet groove 426 and further form the juice outlet gap, which can increase the juice outlet area of ​​the juice outlet gap, thereby improving the juice outlet efficiency of the juice squeezing barrel. Since the extrusion sheet can rotate in the installation groove and fit with the adjacent fixed extrusion sheet when the screw is extruded, even when the extrusion sheet is subjected to a large extrusion force, the suspended juice outlet groove part will also be deformed to reduce the gap of the juice outlet groove, thereby reducing the area of ​​the juice outlet gap to improve the taste of the juice. This is because, for different processed ingredients, for example, when processing soft ingredients such as watermelon, the juice yield of the ingredients is high, and the juice needs to be discharged quickly, so a larger juice discharge gap is required. Since the ingredients are soft, the extrusion force applied by the screw on the extrusion sheet through the ingredients is relatively small, and the area of ​​the juice discharge gap between the extrusion sheet and the fixed extrusion sheet is increased, thereby ensuring the juice discharge efficiency and allowing the juice to be discharged quickly; while for hard ingredients such as carrots, the juice yield of the ingredients is low and contains more pomace fiber, and the extrusion force applied by the screw on the extrusion sheet through the ingredients is relatively large, which can fully squeeze the extrusion sheet and the fixed extrusion sheet into fit, and by reducing the area of ​​the juice discharge gap, the pomace is avoided from being discharged from the juice discharge gap, thereby ensuring the taste of the juice, and the relatively low juice yield of the ingredients can also meet the juice discharge speed requirements.

[0045] Preferably, the fixed extrusion sheet 43 is formed extending in the circumferential direction on the transverse section of the juice squeezing barrel 4, and the inner side wall of the upstream end of the fixed extrusion sheet 43 is provided with a seating portion 432, and the seating portion 432 is formed by being recessed outward along the inner side wall of the fixed extrusion sheet 43, and the fitting portion 422 fits on the seating portion 432. The inner side walls of the movable extrusion sheet 42 and the fixed extrusion sheet 43 are arc surfaces with the same radius, so that when the movable extrusion sheet 42 and the fixed extrusion sheet 43 overlap and fit each other, the inner side walls of the movable extrusion sheet 42 and the fixed extrusion sheet 43 are located on the same circumference. The same circumference here refers to the fact that the radius of the inner side walls of the movable extrusion sheet 42 and the fixed extrusion sheet 43 are the same on the transverse section of the juice squeezing barrel, so that the extrusion sheet and the fixed extrusion sheet can be in the same processing state when they are rotated and ground with the screw 3. It should be noted that the same circumference means that under ideal conditions, the two are located on the same circumference within an acceptable tolerance range. As Fig.10 As shown, the upstream end defined here is the end that first contacts a specific point of the screw in the direction of screw rotation, and the end that contacts the characteristic point of the screw later is the downstream end.

[0046] Preferably, the fixed extrusion sheet 43 is provided with a fixing groove 431 at the lower end, and the fixed ring 44 is provided with a boss 442 corresponding thereto, and the fixed ring 44 is fixedly connected to the lower end of the fixed extrusion sheet 43 through the boss 442 and the fixing groove 431. The boss 442 is also provided with a fixing hole 4421, and the fixing hole 4421 passes through the fixed ring 44, and a shaft hole sink 4422 is also provided on one side of the lower end surface of the fixing hole 4421. Preferably, the juice squeezer 4 is provided with a fixing member such as a screw at the fixing hole 4421, and the fixing ring 44 is fixed to the lower end of the fixed extrusion sheet 43 by the screw, and the screw rod can be hidden in the shaft hole sink 4422. By providing the annular fixing ring 44, the lower ends of the movable extrusion sheet 42 and the fixed extrusion sheet 43 are limited, so as to avoid the extrusion sheet being easily deformed by excessive extrusion of the screw rod when the lower end is suspended, thereby improving the strength of the extrusion sheet and ensuring the normal operation of the juice squeezer. A limiting groove 441 is further provided at the lower end of the fixing ring 44 , and the limiting groove 441 cooperates with the limiting protrusion 25 on the bottom wall of the juice collecting chamber 2 to limit the position of the juice squeezing cylinder 4 .

[0047] Preferably, the juicer 4 further comprises a lower stop 443 disposed on the fixed ring 44, and when the movable extrusion sheet 42 rotates to the filtering position, the movable extrusion sheet 42 overlaps and fits with the adjacent fixed extrusion sheet 43. When the movable extrusion sheet 42 is pushed and extruded by the screw, especially when processing hard food materials, the extrusion sheet is easily deformed due to excessive extrusion force. Although the fixed extrusion sheet on the outside can withstand a certain extrusion force and maintain the gap of the juice outlet channel, when the extrusion sheet and the fixed extrusion sheet are continuously extruded, they will deform outwards and increase the gap between the inner wall of the juicer and the screw, thereby reducing the grinding and crushing efficiency of the extrusion assembly. The lower stop is provided to block the extrusion sheet from rotating outwards and withstand the extrusion force of the extrusion sheet, so as to protect the extrusion sheet and the fixed extrusion sheet, effectively ensure that the extrusion sheet and the fixed extrusion sheet are always in a preset state, maintain the grinding and crushing efficiency of the extrusion assembly, and thereby ensure the normal processing of the juicer. The extrusion sheet can be switched between the filtering position and the cleaning position by simply rotating the extrusion sheet. Therefore, the extrusion sheet usually only needs to be rotated within a certain angle, and does not have to be set to a full circle rotation state. The limiting structure is usually used to protect the extrusion sheet to prevent the extrusion sheet from being excessively squeezed. Therefore, the limiting structure is usually set at the edge or periphery of the rotation range of the extrusion sheet, that is, when the extrusion sheet is rotated to the filtering position, the limiting structure does not work or just fits. In this way, the limiting structure can fully protect the extrusion sheet.

[0048] By providing an extrusion sheet, the extrusion sheet is used to generate a juice discharge gap by rotating when subjected to the extrusion force of the screw, and when the juice barrel needs to be cleaned, the juice discharge gap is opened by moving the extrusion sheet, so as to facilitate the cleaning of the juice barrel. The structure is simple and convenient, and the extrusion sheet is directly provided on the juice barrel, and does not need to be assembled by disassembly or the like, so the structure is more reliable. Further, positioning ribs are provided on the bottom wall of the juice collecting chamber, and the extrusion sheet is limited by the positioning ribs, so that the bottom end of the extrusion sheet can be prevented from being squeezed by the screw when it is suspended in the air, and the extrusion sheet is effectively protected.

[0049] It can be understood that the fixing ring can also be fixedly connected to the fixing extrusion sheet by welding or other methods.

[0050] It can be understood that the inner side walls of the extrusion sheet and the fixed extrusion sheet are not on the same circumference, so that a height difference is formed between adjacent extrusion sheets and the fixed extrusion sheet, thereby forming an extrusion cutting position that cooperates with the screw to improve the crushing efficiency.

[0051] It can be understood that the juice squeezing cylinder can be directly plugged into the bottom wall of the juice collecting chamber through the squeezing sheet without providing the fixing ring.

[0052] It can be understood that the extrusion sheet is provided with a through hole, the fixing ring is provided with a rotating shaft passing through the through hole, and the rotating shaft is further connected to the cylinder so that the extrusion sheet can be rotatably fixed on the cylinder. Alternatively, the fixing ring is a metal piece that is integrated with the rotation, the fixing ring is annular, and the rotation is fixed to the fixing ring, for example, fixed as a whole by welding, and the extrusion sheet is fixedly connected to the cylinder through the fixing ring and the rotation.

[0053] It can be understood that the fixed extrusion sheet and the inner side wall of the extrusion sheet are both provided with extrusion ribs, the extrusion ribs protrude toward the center of the juice squeezing cylinder, and the axial extension direction of the extrusion ribs is the same as the setting direction of the screw thread. Alternatively, the axial extension direction of the extrusion ribs is opposite to the setting direction of the screw thread, for example, the extrusion ribs are perpendicular to the setting direction of the contacting threads.

[0054] It is understandable that the slag blocking module may not be provided at the slag discharge through hole, so that the slag in the juice collecting chamber can be discharged directly through the slag discharge port.

[0055] It is understandable that the contact part of the squeeze sheet is also provided with a groove for juice discharge to increase the area of ​​the juice discharge gap. Alternatively, the squeeze sheet can be in contact with the inner wall of the juice cylinder instead of directly in contact with the adjacent squeeze sheet to increase the juice discharge gap between adjacent squeeze sheets.

[0056] Embodiment 2.

[0057] As a second embodiment of the squeeze juicer described in the utility model, Figure 12-14 As shown, compared with the first embodiment, in this embodiment, only a rotatable extrusion sheet is provided at the lower end of the cylinder.

[0058] like Figure 12-14 As shown, the juice squeezing barrel 4 includes a barrel body 41 and a plurality of movable squeezing sheets 42, and the movable squeezing sheets 42 are arranged along the circumference of the juice squeezing barrel 4, and the movable squeezing sheets 42 can rotate along the axial direction. When the screw 3 is rotated, the screw 3 pushes the food and further pushes the movable squeezing sheets 42 to rotate, and overlaps and fits with adjacent movable squeezing sheets 42 to form a juice outlet gap 5 between adjacent movable squeezing sheets 42.

[0059] The movable extrusion sheet 42 includes a body 421 and a fitting portion 422, the body 421 is provided with a through hole 4213, and the juice squeezer 4 also includes a rotating shaft 64 passing through the through hole 4213. Preferably, the rotating shaft 64 is set as a metal shaft to improve the strength of the rotating shaft 64, and the rotating shaft 64 passes through the through hole 4211 to be fixedly connected with the body 421. Preferably, the juice squeezer 4 also includes a fixing ring 44 arranged at the bottom end of the movable extrusion sheet 42. Preferably, the body 421 is provided with an upper shaft hole, and the fixing ring 44 is provided with a lower shaft hole. The two ends of the rotating shaft 64 are fixedly connected to the upper shaft hole and the lower shaft hole respectively, so as to clamp the movable extrusion sheet 42 between the body 421 and the fixing ring 44.

[0060] The inner side wall at the lower end of the body 421 is also provided with an upper limit platform 411, the inner side wall at the upper end of the fixing ring 44 is also provided with a lower limit platform 443, and the axial ends of the fitting portion 422 are provided with retaining ribs 4221, and when the movable extrusion sheet 42 is pushed outward by the screw to rotate, the retaining ribs 4221 can respectively fit with the upper limit platform 411 and the lower limit platform 443. Preferably, when the fitting portion 422 fits with the adjacent movable extrusion sheet 42, the retaining ribs 4221 do not contact with the upper limit platform 411 and the lower limit platform 443, and only when the movable extrusion sheet 42 is subjected to a large extrusion force, the retaining ribs 4221 fit with the upper limit platform 411 and the lower limit platform 443 to prevent the movable extrusion sheet 42 from being excessively extruded and deformed.

[0061] A plurality of extrusion sheets are provided, and the extrusion sheets are pushed by the screw during operation (the screw and the extrusion sheets are not in direct contact, the screw pushes the food, and further pushes the extrusion sheets through the food, that is, the screw provides a power source and finally pushes the extrusion sheets), and the adjacent extrusion sheets overlap and adhere to each other to form a juice outlet channel at the adhesion, so that there is no need to set a gap between the juice outlet channels when the juice barrel is processed, and it is also avoided that the extrusion sheets need to continuously withstand the extrusion force and then produce fatigue deformation when they are fixedly set, so that the juice outlet channel of the juice barrel can always be in a preset gap size, ensuring the purity of the juice, and improving the processing taste of the original juice machine. At the same time, the movable extrusion sheet can be easily detached from the juice outlet position, so that the juice outlet channel of the juice barrel is fully opened and convenient and quick to clean. Furthermore, the movable setting of the extrusion sheet is limited to the body of the juice barrel, and the user does not need to disassemble the extrusion sheet. In this way, especially for the formation of the outlet channel position when the juice is kept in the juice state, it is only necessary to install the screw in place to achieve efficient juice outlet under the push of the screw, which is more convenient and quick to use.

[0062] It can be understood that the juice squeezing cylinder may not be provided with the fixing ring, and the bottom end of the movable squeezing cylinder is directly fixed to the bottom wall of the juice collecting chamber.

[0063] It is understandable that the fixing ring can be configured as a metal part integrated with the rotating shaft. The fixing ring is configured as an annular shape, the rotating shaft is fixed to the annular fixing ring, for example, fixed as an integral whole by welding, and the extrusion sheet is fixedly connected to the cylinder through the fixing ring and the rotating shaft.

[0064] It can be understood that the body and the fixing ring are respectively provided with protrusions, and the protrusions are inserted into the through holes of the extrusion sheet to position the extrusion sheet, and the extrusion sheet rotates around the protrusions.

[0065] The above is only a preferred embodiment of the present invention and is not intended to limit the scope of implementation of the present invention. That is, all equivalent changes and modifications made according to the present invention are covered by the scope of the claims of the present invention and will not be listed one by one here.
