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 juicer uses screw extrusion to separate the juice and pomace of the ingredients. Usually, the screw is set at a lower processing speed, which can avoid oxidation of the juice and thus improve the processed taste of the juice. The existing juicer usually uses a filter or filter grid to separate the juice and pomace. The filter structure is easily blocked by pomace during juice extraction, which affects the normal juice extraction. The juice extraction efficiency is low and affects the juice extraction rate of the ingredients. The technical solution using the filter structure is gradually weakened and eliminated.

[0003] The use of a filtering bar structure to filter juice is a relatively mature solution for existing juicers. There are two solutions using bar filtration in the prior art. Among them, one solution directly sets a bar structure on the juice squeezing barrel. The bar structure will deform when squeezed and can adapt to the discharge of juice and the filtering of fruit residue; the other structure sets inserted bars, that is, two halves of the juice squeezing barrel structure are set, and the bar structure is set separately, and there is a gap between adjacent bars, and the other half of the juice squeezing barrel is set with a similar bar structure, and the two halves of the bar structure are respectively inserted into the gap to form a complete bar structure, and a juice outlet channel is formed between the bars.

[0004] Although the use of bars in the prior art facilitates filtering and avoids cleaning problems caused by residues remaining in the filter, the existing integrated bar structure still requires laborious cleaning when the residues are squeezed into the gaps between the bars. In order to improve the purity of the juice, the gap between the bars needs to be set as small as possible, which further causes trouble in cleaning. Another convenience is to disassemble the two bar assemblies for cleaning, but this will make the structure of the juicer complicated. Both parts need to be cleaned, and the user is required to reassemble them by himself, which makes the structure complicated and the cleaning complicated. The assembled structure cannot fully guarantee the reliability of the juice outlet gap, thereby affecting the normal juice outlet of the juicer. Utility Model Content

[0005] The utility model aims to provide a squeeze juicer which can fully guarantee juice extraction efficiency and is easy to clean by adjusting its own structure without adding structural parts and reducing user operations.

[0006] The utility model provides an extruding juicer that is easy to clean, comprising a main unit with a motor installed therein, 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, wherein the extruding assembly comprises a screw and a juice squeezing barrel sleeved outside the screw, wherein the juice squeezing barrel comprises a barrel body and an extruding sheet, the barrel body is sleeved outside the screw, the extruding sheet is located at the lower end of the barrel body and has a plurality of sheets, at least some of which can rotate axially so that the extruding sheet has a filtering position and a cleaning position, when the extruding sheets are in the filtering position, adjacent extruding sheets overlap and fit each other to form a juice outlet channel, and when the extruding sheets are in the cleaning position, adjacent extruding sheets are away from each other. The juice squeezing barrel is provided with a barrel body and a squeezing sheet, the barrel body itself is sleeved outside the screw, the squeezing sheets are provided with a plurality of sheets which overlap and fit each other and are sleeved outside the screw, and the movable squeezing sheets have a filtering position and a cleaning position. When in the filtering position, the squeezing sheets fit each other under the squeezing action of the screw to form a juice outlet gap, thereby ensuring the juice outlet efficiency and the purity of the juice; and when the squeezing sheets are in the cleaning position, the squeezing sheets are away from each other to form a gap of sufficiently large width, thereby facilitating the cleaning of the fruit residue remaining in the juice outlet gap, thereby facilitating the user to clean the juice squeezing barrel, and since the squeezing sheets do not need to be removed and the juice squeezing barrel does not need to be disassembled, the trouble of resetting during use is reduced, and the squeezing sheets will be reset under the squeezing action of the screw, thereby ensuring the normal and efficient juice outlet of the juice squeezing barrel.

[0007] As a further preferred embodiment of the extrusion juicer described in the present application, the juicer barrel is further provided with a limiting structure that blocks the rotation of the extrusion sheet. When the extrusion sheet is squeezed by the screw, it will be subjected to a large extrusion force of the screw. The extrusion sheet may be deformed to affect the juice output, or when the extrusion sheet is moved to the cleaning position and is still subjected to an extrusion force, there is a risk of excessive outward expansion. By providing a limiting structure, when the extrusion sheet is subjected to excessive extrusion force, the limiting structure can ensure that the extrusion sheet is in a reasonable position to prevent damage to the extrusion sheet when it is subjected to excessive extrusion. Preferably, the limiting structure is usually arranged outside the filtering position and the cleaning position. For example, the extrusion sheet is provided with a certain rotation angle, and the filtering position and the cleaning position are provided on both sides of the rotation angle, and the limiting structure is provided outside the rotation angle.

[0008] As a further preferred solution of the squeeze juicer described in the present application, the limiting structure includes a limiting platform arranged on the juice squeezing barrel, and the limiting platform can block the squeezing sheet when the squeezing sheet rotates. The limiting structure is set as a limiting platform, and the squeezing sheet is directly blocked by the limiting platform, which has a simple structure and can effectively block the squeezing sheet; the limiting platform can be directly set on the juice squeezing barrel, and only works when the squeezing sheet needs to be limited, and will not affect the normal operation of the juice squeezing barrel, thereby ensuring efficient juice output of the juice squeezing barrel.

[0009] As a further preferred embodiment of the squeeze juicer described in the present application, the limiting structure includes a blocking rib protruding along the axial direction of the squeeze sheet, and the blocking rib can fit with the inner wall of the juice barrel to prevent the squeeze sheet from rotating. Blocking ribs protruding in the axial direction are arranged at both ends or one end of the squeeze sheet, and the blocking ribs extend upward or downward from the axial ends of the squeeze sheet, so that when the squeeze sheet is in the filtering position and is squeezed by the screw, the squeeze ribs can directly fit with the inner wall of the squeeze barrel to produce a blocking effect.

[0010] As a further preferred embodiment of the squeeze juicer described in the present application, the squeeze sheet includes a body and a fitting portion, the axis of the squeeze sheet passes through the body, the fitting portion is formed by the body extending radially outward, and when the squeeze sheet is in the filtering position, the fitting portion fits with the adjacent squeeze sheet. A body and a fitting portion are provided, the axis of the squeeze position passes through the body, the body can rotate around the axis, the body occupies the main volume of the squeeze sheet, and the fitting portion is provided, and the fitting portion is overlapped and fitted with the adjacent squeeze sheet. Preferably, the fitting portion can be provided with a thinner size to facilitate fitting with the adjacent squeeze sheet to produce a juice outlet channel, and the body can withstand the squeezing force of the squeeze sheet, so as to better protect the squeeze sheet.

[0011] As a further preferred embodiment of the squeeze juicer described in the present application, the outer side wall where the fitting part fits with the adjacent squeeze sheets is provided with filter ribs, and the filter ribs fit with the adjacent squeeze sheets and form a juice outlet channel between the filter ribs. The filter ribs are provided on the outer side wall where the fitting part fits with the adjacent squeeze sheets, and when the fitting part fits with the adjacent squeeze sheets, the filter ribs fit with the adjacent squeeze sheets to increase the gap size between the two adjacent squeeze sheets, thereby forming a juice outlet channel between the filter ribs, which can increase the unit juice outlet area and improve the juice outlet efficiency. It should be noted that filtering ribs are provided to improve the juice outlet channel to improve the juice outlet efficiency, which may have different effects on different ingredients. For example, ingredients with a higher juice outlet rate, such as watermelon, require a higher juice outlet efficiency to ensure rapid juice outlet, and the ingredients themselves are relatively soft, so the force exerted by the screw extrusion force on the extrusion sheet is also relatively small, and the extrusion sheet will not be over-extruded, which can also ensure that the filtering ribs provide a larger juice outlet channel size; while for ingredients with a lower juice outlet rate, such as carrots, an overly large juice outlet channel is not required, and it is also necessary to avoid excessive discharge of pomace fibers when the juice outlet channel is too large, thereby affecting the taste of the juice. At this time, when the ingredients are squeezed by the screw, they will exert a greater force on the extrusion sheet. When subjected to a larger extrusion force, the filtering ribs will further not fit with the adjacent extrusion sheet to reduce the size of the juice outlet channel, thereby ensuring the juice outlet efficiency while improving the taste of the juice.

[0012] As a further preferred embodiment of the squeeze juicer described in the present application, the inner side wall of the fitting portion and the screw rod is provided with squeeze ribs protruding toward the center of the juice barrel. The squeeze ribs are provided inside the fitting portion, and when the screw rod is working, the squeeze ribs can interact with the squeeze ribs to improve the squeeze efficiency. At the same time, the squeeze ribs reduce the gap between the juice barrel and the screw rod, so that the food passing through the squeeze ribs can be more fully ground and crushed, thereby improving the juice extraction efficiency. Furthermore, the squeeze ribs are usually located on the upstream side of the juice outlet channel of the squeeze plate, so that the squeezed juice can be quickly discharged from the juice outlet channel, ensuring fast and efficient juice extraction.

[0013] As a further preferred solution of the squeeze juicer described in the present application, the body is fitted with the fitting part of the adjacent squeeze sheet, and the side wall of the body fitted with the adjacent fitting part is provided with support ribs, and the support ribs are fitted with the adjacent fitting part and form a juice outlet channel between the support ribs. The support ribs are provided on the body, and the juice outlet channel is formed by using the support ribs and the adjacent fitting part. The support ribs can increase the area of ​​the juice outlet channel and improve the juice outlet efficiency. They can also be deformed appropriately when subjected to large extrusion to reduce the area of ​​the juice outlet channel and ensure the purity of the juice.

[0014] As a further preferred embodiment of the squeeze juicer described in the present application, the juicer barrel further comprises a fixing ring located at the bottom of the squeeze sheet, and the bottom of the squeeze sheet is rotatably connected to the fixing ring. A fixing ring is arranged at the bottom of the juicer barrel, and the bottom of the squeeze sheet is connected to the fixing ring, so that the bottom of the squeeze sheet can be limited to avoid the bottom of the squeeze sheet being suspended when only the upper end of the squeeze sheet is fixed, which can enhance the strength of the squeeze sheet itself and prevent the squeeze sheet from being damaged and affecting the normal operation of the juicer barrel and the juicer.

[0015] As a further preferred embodiment of the squeeze juicer described in the present application, an annular positioning rib is provided at the bottom of the juice collecting chamber, the juice squeezing barrel is inserted into the positioning rib and fixedly matched with the juice collecting chamber, and the positioning rib is sleeved on the outside of the squeezing sheet and limits the rotation of the squeezing sheet. Positioning ribs are directly provided at the bottom of the juice collecting chamber, and the juice squeezing barrel is inserted into the positioning rib and fixedly matched with the juice collecting chamber. When the bottom of the squeezing sheet is suspended in the air, the positioning rib can directly limit the bottom of the squeezing sheet for protection; when a fixed structure is provided at the bottom of the juice squeezing barrel, it can also cooperate with the fixed structure to enhance the protection of the squeezing sheet. The fixed rib can also limit the outside of the squeezing sheet to prevent the squeezing sheet from being damaged when it is subjected to excessive squeezing force, so as to provide better protection for the squeezing juice squeezing barrel.

[0036] Embodiment 1.

[0037] As a first embodiment of the convenient and clean squeeze juicer described in the utility model, Figure 1-9 As 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 body 31 , a screw shaft 32 and screw teeth 33 . Preferably, the screw shaft 32 is a metal piece and is integrally formed with the screw body 31 , and the screw teeth 33 are arranged on the outer surface of the screw body 31 .

[0038] The bottom wall of the juice collecting chamber 2 is provided with an annular positioning rib 23, and the juice squeezing tube 4 can be 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 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 part located outside the positioning rib 23 and a slag discharge part located inside the positioning rib 23, wherein the juice discharge part is connected to the juice outlet 22, and the slag discharge part 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 filtering section to the juice discharge part.

[0039] like Figure 3-5As shown, the juice squeezer 4 includes a barrel 41 and an extrusion sheet. The barrel 41 is sleeved on the upper section of the screw 3. The extrusion sheet is located at the lower end of the barrel 41 and is provided in plurality. Preferably, the extrusion sheet includes an alternately arranged movable extrusion sheet 42 and a fixed extrusion sheet 43. The fixed extrusion sheet 43 is integrated with the barrel 41, or the fixed extrusion sheet 43 is fixedly connected to the barrel 41. The movable extrusion sheet 42 is rotatably provided at the lower end of the barrel 41, so that the movable extrusion sheet 42 has the following features on the juice squeezer 4: Figure 4 The filter position, as well as Figure 5 The cleaning position shown. When the movable extrusion sheet 42 is in the filtering position, the movable extrusion sheet 42 and the adjacent fixed extrusion sheet 43 overlap and fit with each other, and a juice outlet channel 5 is formed between the movable extrusion sheet 42 and the fixed extrusion sheet 43. When the screw 3 rotates in the juice squeezing barrel 4, the screw 3 pushes the food to cut, grind and crush the food between the screw 3 and the juice squeezing barrel 4. The screw 3 pushes the food and further pushes the movable extrusion sheet 42, so that the movable extrusion sheet 42 rotates and overlaps and fits with the adjacent fixed extrusion sheet 43 to reach the filtering position. In this way, the juice produced by the extrusion assembly is filtered and discharged through the juice outlet channel. When the juice squeezing barrel 4 needs to be cleaned, the user can move the movable extrusion sheet 42 to make the movable extrusion sheet 42 reach the filtering position as shown. Figure 5 In the cleaning position shown, at this time, the movable squeezing sheet 42 is away from the fixed squeezing sheet 43 to open the juice outlet channel 5, so that the food residues such as pomace remaining in the juice outlet channel can be cleaned very easily.

[0040] The side wall of the barrel 41 is provided with auxiliary filtering holes 40. When the screw 3 is extruded and matched with the extrusion section of the barrel 41, part of the juice produced by extrusion can be discharged from the auxiliary filtering holes 40, so as to avoid that when all the juice needs to be discharged from the filtering section, the amount of juice is too large, so that the juice cannot be effectively discharged and is driven by the pomace to be discharged from the residue outlet. The inner wall of the barrel 41 is also provided with juice squeezing ribs 45. The juice squeezing ribs 45 can be only provided in the extrusion section, and the juice squeezing ribs 45 can also extend downward from the extrusion section to the filtering section. The juice squeezing ribs 45 can cooperate with the screw 3 to reduce the gap between the screw 3 and the inner wall of the juice squeezing barrel 4, so as to improve the extrusion and crushing efficiency of the extrusion assembly and improve the juice yield.

[0041] Preferably, Figure 6-9As shown, the juice squeezer 4 further comprises a fixing ring 44 located at the lower end of the squeezing sheet, a fixing groove 431 is provided at the lower end of the fixed squeezing sheet 43, and the fixing ring 44 is provided with a boss 442 corresponding thereto, and the fixing ring 44 is fixedly connected to the lower end of the fixed squeezing sheet 43 through the boss 442 and the fixing groove 431. An upper shaft hole 62 is provided at the lower end of the cylinder body 41 located between the fixed squeezing sheets 43, and the fixing ring is provided with a lower shaft hole 63. The movable squeezing sheet 42 is provided with a rotating shaft 61 protruding in the axial direction at both ends along the axial direction, and the rotating shafts 61 at both ends are respectively inserted into the upper shaft hole 62 and the lower shaft hole 63, so as to pull the movable squeezing sheet 42 between the cylinder body 41 and the fixing ring 44, and the movable squeezing sheet 42 can rotate along the rotating shaft 61. By setting an annular fixing ring 44, the lower ends of the movable extrusion piece 42 and the fixed extrusion piece 43 are limited, so as to avoid the extrusion piece being easily deformed by excessive extrusion of the screw when the lower end of the extrusion piece is suspended, thereby improving the strength of the extrusion piece and ensuring the normal operation of the juice squeezer.

[0042] Preferably, the juicer 4 is also provided with a limiting structure for blocking the rotation of the extrusion sheet, and the limiting structure includes a lower limiting platform 443 provided on the fixed ring 44. 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, the movable 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, the movable extrusion sheet and the fixed extrusion sheet will deform outward when continuously extruded, thereby increasing 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 limiting platform is provided to block the outward rotation of the movable extrusion sheet and withstand the extrusion force of the movable extrusion sheet, so as to protect the movable extrusion sheet and the fixed extrusion sheet, effectively ensure that the movable 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 original juice machine. 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.

[0043] 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 and extends outward, so that the axis of the extrusion sheet passes through the body 421. The fitting portion 422 is formed by the body 421 extending outward in the radial direction, that is, on the cross section of the movable extrusion sheet 42 perpendicular to the axis, the fitting portion 422 extends outward. 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 channel 5 between adjacent extrusion sheets.

[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 channel 5. The filter rib 425 is used to form the juice outlet groove 426 and further form the juice outlet channel, which can increase the juice outlet area of ​​the juice outlet channel, thereby improving the juice outlet efficiency of the juice squeezing barrel. Since the movable extrusion sheet can rotate during screw extrusion and make adjacent extrusion sheets fit together, even when the movable 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 channel 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 outlet channel is required. Since the ingredients are soft, the extrusion force applied by the screw on the movable extrusion sheet through the ingredients is relatively small, and the area of ​​the juice outlet channel between the movable extrusion sheet and the fixed extrusion sheet is increased, thereby ensuring the juice outlet 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 fibers, and the extrusion force applied by the screw on the movable extrusion sheet through the ingredients is relatively large, which can fully squeeze the movable extrusion sheet and the fixed extrusion sheet into fit, and by reducing the area of ​​the juice outlet channel, the pomace is avoided from being discharged from the juice outlet channel, thereby ensuring the taste of the juice, and the relatively low juice yield of the ingredients can also meet the juice outlet speed requirements.

[0045] 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 juice outlet channels are formed on both the upstream and downstream sides of the extrusion sheet, which can improve the juice outlet efficiency. The side wall where the main body 421 fits with the adjacent fixed extrusion sheet 43 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 outlet channel 5.

[0046] It should be noted that if Figure 4 As shown, the overlapping and fitting of the extrusion sheets defined in the utility model means that adjacent extrusion sheets have overlapping parts in the radial direction, that is, one of the extrusion sheets is located on the outside and the other adjacent extrusion sheet is located on the inside, so that the juice outlet channel formed has a channel portion extending along the circumferential direction. The advantage of such a setting is that when the movable extrusion sheet is rotated by the extrusion force of the screw, the movable extrusion sheet moves outward and continues to fit with the adjacent fixed extrusion sheets, thereby ensuring that the juice outlet channel 5 located between the two extrusion sheets is always under the effect of pre-tightening pressure to ensure the preset gap size, and the gap between the existing bars will not become larger when squeezed, thereby causing the residue to be discharged from the gap. Therefore, the scheme of the present application can always keep the purity of the juice, so that the juice of the juicer tastes better. Even if the extrusion sheet is deformed after long-term use, the movable extrusion sheet can still keep in contact with the fixed extrusion sheet when subjected to the extrusion force of the screw, thereby ensuring the integrity of the juice outlet channel and controllable gap, and will not be deformed after long-term use like the existing grid bars, which will affect the normal juice outlet of the juicer. The juicer of the present application can maintain a consistent juice outlet taste throughout the product life cycle. When it is necessary to clean the juice barrel, the movable extrusion sheet can be moved to the cleaning position to separate the movable extrusion sheet from the fixed extrusion sheet. Figure 5 As shown, at this time, the juice outlet channel between two adjacent squeezing sheets is completely opened, and the fruit residue remaining in the juice outlet channel can be cleaned very conveniently. In this way, by changing the juice outlet channel from being located between two circumferential bars to being located between two squeezing sheets in the radial direction, the contradiction between the existing bars is broken, that is, the juice outlet taste and juice outlet efficiency of the juice squeezing barrel can be always maintained, and the normal cleaning of the juice squeezing barrel is also convenient.

[0047] By setting the extrusion sheet and axially rotating the extrusion sheet, the extrusion sheet has different functions at different positions, such as the filtering position formed when the extrusion sheets overlap and fit each other, and the cleaning position when the extrusion sheet is moved to open the juice outlet channel. The structural setting of the juicer tube itself is used to achieve different functions, breaking the contradictions of the grid solution in the prior art, changing the juice outlet method and the cleaning method, thereby improving the juice outlet efficiency and facilitating the cleaning of the juicer tube, while meeting various needs of the juicer tube.

[0048] It can be understood that the movable extrusion sheets and the fixed extrusion sheets are arranged in the same shape and are distributed along the circumference of the filter section. The extrusion sheets are arranged in a fan shape or have steps or steps so that adjacent extrusion sheets overlap and fit each other.

[0049] 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.

[0050] It can be understood that the extrusion sheet has a protruding retaining rib axially arranged, and the retaining rib can fit with the inner wall of the juice squeezing tube. When the extrusion sheet is excessively deformed due to the push of the screw, the retaining rib can prevent the extrusion sheet from excessive deformation to protect the extrusion sheet.

[0051] It can be understood that the extrusion ribs may be provided with extrusion grooves on the inner wall that cooperate with the screw, so as to improve the cutting effect and guide the juice out through the extrusion grooves.

[0052] Embodiment 2.

[0053] As a second embodiment of the convenient and clean squeeze juicer described in the utility model, Figure 10-12 As shown, compared with the first embodiment, the extrusion sheets in this embodiment are all configured as movable extrusion sheets.

[0054] like Figure 10-12 As shown, the extrusion section 4 includes a cylinder 41 and a plurality of movable extrusion sheets 42, the movable extrusion sheets 42 are arranged along the circumference of the juice squeezing cylinder 4, and the movable extrusion sheets 42 can rotate along the axial direction, so that the movable extrusion sheets have the following Fig.11 The filter positions shown, and Fig.12 When the screw 3 is rotating, the screw 3 pushes the food and further pushes the movable extrusion sheet 42 to rotate, and overlaps and fits with adjacent movable extrusion sheets 42 to form a juice outlet channel 5 between adjacent movable extrusion sheets 42, so that the movable extrusion sheet 42 has a juice outlet function; when the juice cylinder 4 needs to be cleaned, the movable extrusion sheet 42 is moved to the cleaning position to open the juice outlet channel, so that the residue and the like remaining in the juice outlet channel can be easily cleaned.

[0055] 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 4213 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.

[0056] The juice squeezing tube 4 is also provided with a limiting structure for preventing the extrusion plate from rotating. Preferably, the limiting structure includes an upper limiting platform 411 and a lower limiting platform 443. The upper limiting platform 411 is arranged on the inner side wall of the lower end of the main body 421, and the lower limiting platform 443 is arranged on the inner side wall of the upper end of the fixing ring 44. The axial ends of the fitting portion 422 are provided with retaining ribs 4221. When the movable extrusion plate 42 is pushed outward by the screw to rotate, the retaining ribs 4221 can fit with the upper limiting platform 411 and the lower limiting platform 443 respectively. Preferably, when the fitting portion 422 fits with the adjacent active extrusion sheet 42, the blocking rib 4221 does not contact the upper limit platform 411 and the lower limit platform 443, and only when the active extrusion sheet 42 is subjected to a large extrusion force, the blocking rib 4221 fits with the upper limit platform 411 and the lower limit platform 443 to prevent the active extrusion sheet 42 from being excessively extruded and deformed. By providing the limiting structure, it is possible to avoid excessive deformation of the extrusion portion when it is excessively extruded, so that the extrusion sheet can always be in a preset change state, thereby ensuring the normal and efficient juice discharge of the extrusion sheet, and can also be conveniently switched to the cleaning position to clean the juice squeezing barrel.

[0057] A plurality of movable extrusion sheets are provided, and the movable extrusion sheets are pushed by the screw when working (the screw and the movable extrusion sheets are not in direct contact with each other, the screw pushes the food, and further pushes the movable extrusion sheets through the food, that is, the screw provides a power source and finally pushes the movable extrusion sheets), and adjacent movable 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 constantly bear 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 for convenient and quick cleaning. Furthermore, the movable squeezing piece is movable and limited on the juice squeezing barrel body, and the user does not need to disassemble the movable squeezing piece. In this way, especially for forming a presentation channel position when maintaining the juice discharge condition, it is only necessary to install the screw in place to achieve efficient juice discharge under the push of the screw, which is more convenient and quick to use.

[0058] 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 sheet is directly fixed to the bottom wall of the juice collecting chamber.

[0059] It is understandable that the fixing ring can be configured as a metal piece 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 movable extrusion sheet is fixedly connected to the body through the fixing ring and the rotating shaft.

[0060] 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 movable extrusion sheet to position the movable extrusion sheet, and the movable extrusion sheet rotates around the protrusions.

[0061] Embodiment three.

[0062] As a third embodiment of the convenient and clean squeeze juicer described in the utility model, Fig.13 As shown, compared with the first embodiment, the limiting structure in this embodiment includes a blocking rib arranged on the extrusion sheet.

[0063] like Fig.13As shown, the extrusion sheet 7 is provided with an upper blocking rib 71 and a lower blocking rib 72 at both ends of the axial direction, and the upper blocking rib 71 and the lower blocking rib 72 protrude toward both ends along the axial direction of the extrusion sheet 7. The extrusion sheet 7 is mounted on the juice squeezing barrel 4, and the extrusion sheet 7 has a filtering position and a cleaning position on the juice squeezing barrel 4. In the filtering position, the extrusion sheet 7 overlaps and fits with the adjacent extrusion sheets to form a juice outlet channel for filtering. When the extrusion sheet 7 is over-extruded, the upper blocking rib 71 and the lower blocking rib 72 fit with the inner wall of the juice squeezing barrel 4 to prevent the extrusion sheet 7 from excessively rotating outward, so as to protect the extrusion sheet 7. When the squeezing sheet 7 is in the filtering position, the upper blocking rib 71 and the lower blocking rib 72 are in contact with the inner wall of the juice squeezing tube 4, or a certain gap is provided between the upper blocking rib 71 and the lower blocking rib 72 and the side wall of the juice squeezing tube 4. Only when the squeezing sheet is over-squeezed, the upper blocking rib and the lower blocking rib are in contact with the side wall of the juice squeezing tube to play a protective role.

[0064] Preferably, the inner side walls of the upper blocking ribs 71 and the lower blocking ribs 72 have the same shape as the inner side walls of the extrusion sheet 7, so that when the extrusion sheet 7 is rotated to the filtering position, the upper blocking ribs 71 and the lower blocking ribs 72 can play a normal filtering and squeezing role. Of course, the inner wall of the juice squeezing barrel 4 can also be provided with a groove or a sink for accommodating the upper blocking ribs and the lower blocking ribs, so that the inner wall of the juice squeezing barrel forms a complete wall surface.

[0065] The extrusion sheet 7 is provided with an axial hole 73, and the extrusion sheet 7 is installed on the juice squeezing barrel through the axial hole 73 to switch between the filtering position and the cleaning position. The extrusion sheet 7 is also provided with an extrusion rib 74 toward the center of the juice squeezing barrel, and the extrusion rib 74 is vertically extended and protrudes toward the center of the juice squeezing barrel. When the screw is in the extrusion operation, the extrusion rib can cooperate with the screw to improve the crushing efficiency.

[0066] It can be understood that the upper blocking rib and the lower blocking rib can also be set to have different gaps with the side wall of the juice squeezing barrel, for example, the gap of the upper blocking rib is smaller, while the gap of the lower blocking rib is larger. When the squeezing sheet is in the normal filtering position, the adjacent squeezing sheets fit together. When the excessive squeezing force applied to the squeezing sheet is small, the upper blocking rib fits with the inner wall of the juice squeezing barrel, while there is still a gap between the lower blocking rib and the inner wall. When the excessive squeezing force applied to the squeezing sheet is large, the lower blocking rib further fits with the inner wall of the juice squeezing barrel to withstand the excessive squeezing force at different stages, thereby forming different stages of protection for the squeezing sheet.

[0067] 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.
