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 means of screw extrusion. Background Art

[0002] Juicers use a screw to separate the juice and pomace from the ingredients. Typically, the screw is set at a low processing speed to prevent oxidation of the juice, thereby improving the processed taste of the juice. Existing juicers typically use a filter or filter bars to achieve juice and pomace separation. These filters are easily clogged by pomace during juice extraction, affecting proper juice flow. This results in low juice extraction efficiency and affects the yield of the ingredients. Consequently, the use of filter solutions has been gradually phased out.

[0003] Existing juicers usually have filter bars and screws that work together to squeeze out juice. There are two commonly used bar filtering solutions in the prior art. One is to directly set a bar structure on the juice barrel, forming a filtering gap between the bars, and the juice-discharging gap will adaptively change under the squeeze to meet different juice-discharging requirements. The other solution uses a detachable bar structure, for example, two bars that are inserted into each other, and each bar assembly is provided with interval bars. After insertion, a juice outlet channel is formed between adjacent bars. This structure only needs to disassemble the two bar structures for cleaning, and the larger bar gap can be used for cleaning.

[0004] However, the existing bar structure still has the following technical problems: whether it is the integrated bar structure of solution one or the interleaved bar structure, a juice outlet gap is required between adjacent bars. Such a juice outlet gap is formed during the product production process, and this juice outlet gap is easily affected by product production, and the juice outlet is not stable and reliable; at the same time, the bars will also be deformed when squeezed by the screw, making the juice outlet gap larger. In particular, when subjected to excessive squeezing force, the gap is too large, causing the pomace to flow out of the juice outlet gap, affecting the purity of the juice, and thus affecting the taste of the juice. Furthermore, the pomace of the integrated bar structure of solution one will remain in the juice outlet gap formed by the bars and is inconvenient to clean; although solution two partially solves the cleaning problem, the user needs to disassemble the juicer, clean it separately, reassemble it, and cooperate with the screw, etc. There is even a possibility that the preset installation position cannot be reached during self-assembly, affecting the normal operation of the juicer, causing operational troubles for the user. Utility Model Content

[0005] The purpose of the utility model is to provide a squeeze-type juicer which can always protect the pure taste of juice, reduce user operations and facilitate user cleaning.

[0006] The utility model provides an easy-to-operate extrusion-type juicer, comprising a main unit with a motor, a juice collecting chamber arranged on the main unit, a detachable extrusion assembly arranged in the juice collecting chamber, and a feeding cover covering the juice collecting chamber, wherein the extrusion assembly comprises a screw and a juice squeezing barrel sleeved outside the screw, wherein the juice squeezing barrel comprises a barrel body and an extrusion sheet, the barrel body is annular and sleeved outside the screw, the extrusion sheet is arranged at the lower end of the barrel body and is rotatable along the axial direction, the extrusion sheets are multiple and arranged circumferentially and sleeved outside the screw, the extrusion sheets overlap and adhere to form juice outlet channels between adjacent extrusion sheets. The juice squeezing barrel of the present application is provided with a barrel body and an extrusion sheet, the barrel body is sleeved outside the screw to achieve extrusion cooperation with the screw, an extrusion sheet is provided at the lower end of the barrel body and the extrusion sheet is rotatable along the axial direction, a plurality of extrusion sheets are arranged circumferentially and overlapped, and the juice outlet channel between the extrusion sheets is sleeved outside the screw to form a juice outlet module. With this arrangement, when squeezing juice, the extruding plates directly create a juice channel by the squeezing action of the screw, eliminating the need for the user to manipulate the plates to adjust the gap. Furthermore, the gaps overlap and conform to each other when squeezed by the screw, preventing them from widening and affecting the purity of the juice. When cleaning is necessary, the extruding plates rotate directly on the juicing barrel to reposition, increasing the space between the extruding plates that are farther apart from each other, allowing for easy cleaning of any residue remaining between them. This operation does not require disassembling the juicing barrel; simply shifting the corresponding extruding plates simplifies operation. Repositioning the extruding plates also requires a simple shift, or they can even be automatically reset by the squeezing action of the screw, making it simple and convenient. It should be noted that the overlapping and conforming mentioned here refers to the circumferential overlap of adjacent extruding plates, not the circumferential proximity of adjacent extruding plates. This allows the inner extruding plates to align more closely with the outer extruding plates when subjected to the squeezing force, ensuring that the juice channel does not widen. The axial rotation here means that the rotation center of the squeezing plate is in the same direction as the axis of the juicing barrel, but it does not limit the axis of the squeezing plate to coincide with or be completely parallel to the axis of the juicing barrel. There may also be a certain angle between the rotation axis of the squeezing plate and the center line of the juicing barrel.

[0007] Preferably, the juicing cylinder further includes a fixing ring located at the lower end of the extruding piece, the lower end of the extruding piece being rotatably connected to the fixing ring. The fixing ring secures the bottom of the extruding piece to the bottom, thereby preventing the bottom of the extruding piece from being deformed by the screw when suspended in the air, thereby enhancing the strength of the filtration section of the juicing cylinder and ensuring efficient juice extraction.

[0008] Preferably, the extrusion sheet is provided with rotating shafts or axial holes extending outward at both ends, and the barrel and retaining ring are provided with corresponding axial holes or rotating shafts. With the rotating shafts or axial holes provided at both axial ends of the extrusion sheet, and corresponding axial holes or rotating shafts provided in the barrel and retaining ring, the extrusion sheet can be directly clamped between the barrel and retaining ring, and the rotating shafts and axial holes cooperate to achieve a simple structure. The rotating shafts and axial holes are directly located on the extrusion sheet, the barrel, and the retaining ring, providing a reliable structure and ensuring the strength requirements of the juicer.

[0009] Preferably, the extrusion sheet is provided with an axially arranged through-hole, and the juice squeezer further includes a rotating shaft, which passes through the through-hole and is respectively connected to the barrel and the fixing ring. The extrusion sheet rotates along the rotation and overlaps and fits with each other. A through-hole is provided in the extrusion sheet, and a rotating shaft is provided which passes through the through-hole and is respectively fixedly connected to the barrel and the fixing ring at both ends. The extrusion sheet can rotate along the rotating shaft, and the mounting position of the rotating shaft structure is more reliable. The rotating shaft can also be made of metal to further increase the strength of the rotating shaft and the extrusion sheet, thereby improving the operating reliability of the extrusion sheet.

[0010] Preferably, a cooperating limiting groove and limiting protrusion are provided between the bottom wall of the juice collecting chamber and the fixing ring. Providing the limiting groove and limiting protrusion between the bottom wall of the juice collecting chamber and the fixing ring allows the juice extractor to be more securely mounted on the bottom wall of the juice collecting chamber via the fixing ring. Since the limiting groove and limiting protrusion are arranged on the bottom wall, the juice extractor can be directly installed into place when mounted on the bottom wall of the juice collecting chamber from top to bottom. Furthermore, the cooperating limiting groove and limiting protrusion can also limit the circumferential position of the juice extractor, effectively preventing the juice extractor from rotating when subjected to the extrusion force of the screw, thereby ensuring efficient juice extraction from the juice extractor.

[0011] Preferably, the bottom of the juice collecting chamber is provided with an annular positioning rib, and the bottom of the extrusion piece is inserted into the positioning rib to securely engage with the juice collecting chamber. The bottom wall of the juice collecting chamber directly forms an annular positioning rib, and the extrusion piece is directly inserted into the positioning rib to achieve engagement with the juice collecting chamber. When extrusion is required, the upper end of the extrusion piece is fixedly connected to the barrel, while the lower end is limited by the positioning rib, effectively preventing excessive extrusion when the lower end of the extrusion piece is suspended in the air. When cleaning is required, the lower end of the extrusion piece is suspended in the air, allowing the user to directly move the extrusion piece for easier cleaning, making it more convenient to use.

[0012] Preferably, a rotating shaft and an axial hole are provided between the bottom wall of the juice collecting chamber and the extrusion piece. By providing the rotating shaft and axial hole directly between the bottom wall of the juice collecting chamber and the extrusion piece, when the bottom end of the extrusion piece is positioned and engaged with the bottom wall of the juice collecting chamber, it can also rotate when squeezed by the screw, thereby better forming a juice outlet channel between adjacent extrusion pieces. When the juice squeezing barrel needs to be removed, the rotating shaft and axial hole can be easily separated, making operation convenient.

[0013] Preferably, the juice squeezer is provided with a limiting structure, which prevents the squeeze piece from rotating outward. By providing the limiting structure, when the squeeze piece is subjected to excessive squeezing force, the limiting structure can ensure that the squeeze piece is in a reasonable position, thereby preventing the squeeze piece from being damaged when subjected to excessive squeezing.

[0014] Preferably, the limiting structure includes a limiting platform provided on the juicer, and the limiting platform can block the extrusion piece when the extrusion piece rotates outward. The limiting structure is provided as a limiting platform, and the limiting platform is used to directly block the extrusion piece. The structure is simple and can effectively block the extrusion piece. The limiting platform can be directly provided on the juicer, and no other separate structure is required. It is easy to implement and does not require additional movements during use, making operation faster and more convenient.

[0015] Preferably, the limiting structure includes blocking ribs provided at both axial ends of the extrusion piece, the blocking ribs being adapted to abut against the inner wall of the juicing barrel to block the extrusion piece. Axially protruding blocking ribs are provided at either or both axial ends of the extrusion piece, the blocking ribs extending upward or downward relative to the axial ends of the extrusion piece. Thus, when the extrusion piece is in the filtering position and is squeezed by the screw, the extrusion ribs are adapted to abut against the inner wall of the juicing barrel to produce a blocking effect.

[0037] Example 1.

[0038] As a first embodiment of the convenient-to-operate squeeze juicer described in the present invention, 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. 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 top of the juice collecting chamber 2 to close the upper opening of the juice collecting chamber 2. Food is put into the opening of the feeding cover 1 and falls into the extrusion assembly. 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 collected by the juice collecting chamber 2 and discharged through the juice outlet 22. At the same time, the pomace is also gathered 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 .

[0039] like Figure 3-5 As shown, the juice squeezing barrel 4 includes a barrel body 41 and an extrusion sheet. The barrel body 41 is sleeved on the outside of the upper end of the screw 3. The extrusion sheet is located at the lower end of the barrel body 41 and is provided in plurality. Preferably, the extrusion sheet includes movable extrusion sheets 42 and fixed extrusion sheets 43 that are alternately provided. The fixed extrusion sheet 43 is integral with the barrel body 41, or the fixed extrusion sheet 43 is fixedly connected to the barrel body 41. The movable extrusion sheet 42 is rotatably provided at the lower end of the barrel body 41. A plurality of movable extrusion sheets 42 and fixed extrusion sheets 43 are arranged circumferentially at the lower end of the barrel body 41. When the movable extrusion sheet 42 rotates and overlaps with the fixed extrusion sheet 43, the movable extrusion sheet 42 and the fixed extrusion sheet 43 form a ring and are sleeved on the outside of the lower end of the screw 3. Juice outlet channels 5 are formed in sequence 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 squeeze piece 42 to separate the movable squeeze piece from the fixed squeeze piece 43. Figure 5 As shown, the juice outlet channel 5 is opened, so that the pomace and the like remaining in the juice outlet channel 5 can be conveniently cleaned, thereby achieving convenient cleaning of the juice squeezing cylinder.

[0040] The side wall of the barrel 41 is provided with an auxiliary filtering hole 40. When the screw 3 is pressed and engaged with the extrusion section of the barrel 41, a portion of the juice produced by the extrusion can be discharged from the auxiliary filtering hole 40, thereby preventing the juice from being discharged ineffectively due to the excessive amount of juice when all the juice needs to be discharged from the filtering section, and being driven by the pomace to be discharged from the residue outlet. The inner side wall of the barrel 41 is also provided with a juice rib 45. The juice rib 45 can be provided only in the extrusion section, or the juice rib 45 can extend downward from the extrusion section to the filtering section. The juice rib 45 can cooperate with the screw 3 to reduce the gap between the screw 3 and the inner wall of the juicing barrel 4, thereby improving the extrusion and crushing efficiency of the extrusion assembly and improving the juice yield.

[0041] Preferably, Figure 6-9 As shown, the juice squeezing tube 4 also includes a fixed ring 44 located at the lower end of the squeezing piece, a fixed groove 431 is provided at the lower end of the fixed squeezing piece 43, and the fixed ring 44 is provided with a corresponding boss 442. The fixed ring 44 is fixedly connected to the lower end of the fixed squeezing piece 43 through the boss 442 and the fixed groove 431. The lower end of the cylinder body 41 located between the fixed squeezing pieces 43 is provided with an upper shaft hole 62, and the fixed ring is provided with a lower shaft hole 63. The movable squeezing piece 42 is provided with a rotating shaft 61 protruding axially at both ends along the axial direction. The rotating shafts 61 at both ends are respectively inserted into the upper shaft hole 62 and the lower shaft hole 63 to pull the movable squeezing piece 42 between the cylinder body 41 and the fixed ring 44, and the movable squeezing piece 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 is suspended, thereby improving the strength of the extrusion piece and ensuring the normal operation of the juice squeezer.

[0042] The bottom wall of the juice collecting chamber 2 is provided with an annular positioning rib 23. The juice squeezing barrel 4 can be inserted into the positioning rib 23 via the fixing ring 44, thereby securing the squeezing barrel 4 to the bottom end of the juice collecting chamber 2. A central boss 26 is also provided at the center of the bottom wall of the juice collecting chamber 2. 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 portion located outside the positioning rib 23 and a residue discharge portion located inside the positioning rib 23. The juice discharge portion communicates with the juice outlet 22, while the residue discharge portion communicates with the residue outlet 21. The sidewalls of the positioning rib 23 are also provided with a juice drainage groove 24, which drains juice flowing out of the filtration section to the juice discharge portion.

[0043] Preferably, the juicer 4 is further provided with a stopper structure to prevent the rotation of the extrusion plates. The stopper structure comprises a lower stopper 443 disposed on the fixed ring 44. When the movable extrusion plates 42 rotate to the filtering position, the movable extrusion plates 42 overlap and mate with the adjacent fixed extrusion plates 43. When the movable extrusion plates 42 are pushed and squeezed by the screw, particularly when processing hard ingredients, the movable extrusion plates 42 are susceptible to excessive deformation due to excessive extrusion force. While the outer fixed extrusion plates can withstand a certain amount of extrusion force and maintain a gap in the juice outlet channel, the movable and fixed extrusion plates will deform outward with continued extrusion, increasing the gap between the inner wall of the juicer and the screw, thereby reducing the grinding efficiency of the extrusion assembly. The lower stopper prevents the outward rotation of the movable extrusion plates and withstands the extrusion force of the movable extrusion plates. This protects the movable and fixed extrusion plates, effectively ensuring that they remain in a predetermined state, maintaining the grinding efficiency of the extrusion assembly and thus ensuring proper operation 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.

[0044] The movable extrusion piece 42 includes a main body 421 and a fitting portion 422. The rotating shaft 61 is located at both ends of the main body 421 and extends outward, so that the axis of the extrusion piece passes through the main body 421. The fitting portion 422 is formed by the main body 421 extending radially outward. That is, the fitting portion 422 extends outward on a cross section of the movable extrusion piece 42 perpendicular to the axis. When the movable extrusion piece 42 and the fixed extrusion piece 43 are assembled in sequence, the fitting portion 422 is located on the inner side of the fixed extrusion piece 43. When the screw 3 is in operation, it pushes the material and further pushes the fitting portion 422 to rotate outward, overlapping with the fixed extrusion piece 43 and forming a juice outlet channel 5 between adjacent extrusion pieces.

[0045] Preferably, the inner sidewall of the fitting portion 422 is further provided with extrusion ribs 423. The extrusion ribs 423 extend axially along the juicing barrel 4 and protrude toward the center of the juicing barrel 4 to engage with the screw 3 in an extrusion-coordinated manner, thereby improving the grinding efficiency between the screw 3 and the juicing barrel 4. The outer sidewall of the fitting portion 422 is further provided with filter ribs 425. When the movable extrusion sheet 42 is in contact with the fixed extrusion sheet 43, the filter ribs 425 engage with the fixed extrusion sheet 43, forming juice outlet grooves 426 between the filter ribs 425. The gaps between the filter ribs 425 and the juice outlet grooves 426 together constitute the juice outlet channel 5. Using the filter ribs 425 to form the juice outlet grooves 426 and, further, the juice outlet channel, can increase the juice outlet area of ​​the juice outlet channel, thereby improving the juice outlet efficiency of the juicing 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 area of ​​the juice outlet channel is required. Since the ingredients are soft, the extrusion force exerted by the screw on the movable extrusion piece through the ingredients is relatively small, and the area of ​​the juice outlet channel between the movable extrusion piece and the fixed extrusion piece is increased, thereby ensuring the juice extraction 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. The extrusion force exerted by the screw on the movable extrusion piece through the ingredients is relatively large, which can fully squeeze the movable extrusion piece and the fixed extrusion piece 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 extraction speed requirements.

[0046] Preferably, when the movable extrusion piece 42 rotates so that the fitting portion 422 overlaps and fits with the adjacent fixed extrusion piece 43, the body 421 and the adjacent fixed extrusion piece 43 on the other side are also in an overlapping and fitting state. This allows juice outlet channels to be formed on both the upstream and downstream sides of the extrusion piece, thereby improving juice extraction efficiency. The sidewalls of the body 421 where the body and the adjacent fixed extrusion piece 43 fit together are further provided with support ribs 4211. Outflow juice grooves 4212 are formed between the support ribs 4211. The outflow juice grooves 4212 and the gap between the body 421 and the fixed extrusion piece 43 together constitute the juice outlet channel 5.

[0047] Preferably, the fixed extrusion piece 43 is formed to extend circumferentially on the transverse cross-section of the juice squeezing barrel 4, and the inner side wall of the upstream end of the fixed extrusion piece 43 is provided with a seating portion 432, and the seating portion 432 is formed to be recessed outward along the inner side wall of the fixed extrusion piece 43, and the fitting portion 422 fits on the seating portion 432. Thus, when the movable extrusion piece 42 fits with the fixed extrusion piece 43, the inner side walls of the movable extrusion piece 42 and the fixed extrusion piece 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 piece 42 and the fixed extrusion piece 43 are the same on the transverse cross-section of the juice squeezing barrel, so that the movable extrusion piece and the fixed extrusion piece 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. 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.

[0048] It should be noted that if Figure 4 As shown, the overlapping fitting of the extrusion sheets defined in the present invention 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, and the juice outlet channel formed in this way has a channel part 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, ensuring that the juice outlet channel 5 located between the two extrusion sheets is always under the action of pre-tightening pressure to ensure the preset gap size, and the gap between the existing bars will not become larger when squeezed, causing the fruit residue to be discharged from the gap. Therefore, the solution of the present application can always keep the juice pure, so that the juice of the juicer tastes better. Even if the extrusion piece is deformed after long-term use, the movable extrusion piece can still keep in contact with the fixed extrusion piece when it is squeezed by the screw, thereby ensuring the integrity of the juice outlet channel and the controllable gap, unlike the existing grid bars that are deformed after long-term use and affect the normal juice output of the juicer. The juicer of this application can maintain a consistent juice taste throughout the product life cycle. When it is necessary to clean the juice barrel, the movable extrusion piece can be moved to the cleaning position to separate the movable extrusion piece from the fixed extrusion piece. Figure 5 As shown, the juice outlet channel between two adjacent extrusion plates is now completely open, allowing for easy cleaning of any residue remaining in the channel. This arrangement, by changing the juice outlet channel from being located between two circumferential bars to being located between two radial extrusion plates, eliminates the inconsistency between the existing bars. This ensures consistent juice quality and efficiency, while facilitating easy cleaning of the juicer.

[0049] By setting the extrusion sheet and arranging the extrusion sheet to be rotatable along the axial direction, the extrusion sheet has different functions in 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 barrel 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 barrel, while meeting various needs of the juicer barrel.

[0050] It can be understood that the movable extrusion sheets and the fixed extrusion sheets are set to the same shape and are distributed along the circumference of the filter section. The extrusion sheets are set in a fan shape or have steps or steps, so that adjacent extrusion sheets overlap and fit together.

[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 has a protruding rib arranged axially, and the rib can fit with the inner wall of the juice squeezing barrel. When the extrusion sheet is excessively deformed by the push of the screw, the rib can prevent the extrusion sheet from excessive deformation to protect the extrusion sheet.

[0053] It can be understood that the extrusion ribs can 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.

[0054] Example 2.

[0055] As a second embodiment of the convenient-to-operate squeeze juicer described in the present invention, Figure 10-12 As shown, compared with the first embodiment, the extrusion sheets in this embodiment are all configured as movable extrusion sheets.

[0056] like Figure 10-12 As shown, the extrusion section 4 includes a cylinder 41 and a plurality of movable extrusion pieces 42, the movable extrusion pieces 42 are arranged along the circumference of the juice squeezing cylinder 4, and the movable extrusion pieces 42 can rotate along the axial direction so that the movable extrusion pieces have the following Figure 11 The filter positions shown, and Figure 12The cleaning position shown. When the screw 3 rotates, it pushes the food and further rotates the movable extrusion piece 42, overlapping and fitting with adjacent movable extrusion pieces 42 to form a juice outlet channel 5 between adjacent movable extrusion pieces 42, so that the movable extrusion pieces 42 can function as a juice outlet. When the juice barrel 4 needs to be cleaned, the movable extrusion piece 42 is moved to the cleaning position to open the juice outlet channel, making it easier to clean the fruit residue and the like remaining in the juice outlet channel.

[0057] The movable extrusion piece 42 includes a body 421 and a fitting portion 422. The body 421 is provided with a through hole 4213. The juice squeezer 4 also includes a rotating shaft 64 passing through the through hole 4213. Preferably, the rotating shaft 64 is configured as a metal shaft to enhance the strength of the rotating shaft 64. The rotating shaft 64 passes through the through hole 4213 to be fixedly connected to the body 421. Preferably, the juice squeezer 4 also includes a fixing ring 44 provided at the bottom end of the movable extrusion piece 42. Preferably, the body 421 is provided with an upper shaft hole, the fixing ring 44 is provided with a lower shaft hole, and 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 piece 42 between the body 421 and the fixing ring 44.

[0058] 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 part 422 are provided with retaining ribs 4221. When the movable extrusion plate 42 is pushed outward by the screw, the retaining ribs 4221 can be fitted with the upper limiting platform 411 and the lower limiting platform 443 respectively. Preferably, when the fitting portion 422 fits with the adjacent movable extrusion piece 42, the retaining rib 4221 does not contact the upper limit platform 411 and the lower limit platform 443. Instead, the retaining rib 4221 fits with the upper limit platform 411 and the lower limit platform 443 only when the movable extrusion piece 42 is subjected to a relatively large extrusion force, thereby preventing the movable extrusion piece 42 from being excessively extruded and deformed. By providing the retaining structure, excessive deformation of the extrusion portion when subjected to excessive extrusion can be avoided, allowing the extrusion piece to remain in a predetermined state of change, thereby ensuring normal and efficient juice discharge from the extrusion piece and enabling convenient switching to a cleaning position for cleaning the juicer.

[0059] A plurality of movable extrusion pieces are provided, and the movable extrusion pieces are pushed by the screw during operation (the screw and the movable extrusion pieces are not in direct contact with each other, the screw pushes the food, and further pushes the movable extrusion pieces through the food, that is, the screw provides a power source and ultimately pushes the movable extrusion pieces). Adjacent movable extrusion pieces overlap and adhere to each other to form a juice outlet channel at the joint. In this way, there is no need to set a gap between the juice outlet channels when the juice barrel is processed, and it also avoids the need for the extrusion pieces to constantly withstand the extrusion force and thus fatigue deformation when they are fixed. This allows the juice outlet channel of the juice barrel to always be in a preset gap size, ensuring the purity of the juice and improving the processing taste of the juicer. At the same time, the movable extrusion piece 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 arranged on the juice squeezing barrel body and does not require the user to disassemble the movable squeezing piece. In this way, especially for forming the 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.

[0060] It is understandable that the juicing cylinder may not be provided with the fixing ring, and the bottom end of the movable juicing cylinder is directly fixed to the bottom wall of the juice collecting chamber.

[0061] It is understandable that the fixing ring can be configured as a metal part integral with the rotating shaft. The fixing ring is configured as an annular ring, the rotating shaft is fixed to the annular fixing ring, for example, by welding, and the movable extrusion plate is fixedly connected to the body via the fixing ring and the rotating shaft.

[0062] 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 piece to position the movable extrusion piece, and the movable extrusion piece rotates around the protrusions.

[0063] Example 3.

[0064] As a third embodiment of the convenient-to-operate squeeze juicer described in the present invention, Figure 13 As shown, compared with the first embodiment, the limiting structure in this embodiment includes a blocking rib provided on the extrusion sheet.

[0065] like Figure 13As shown, the extrusion piece 7 is provided with an upper blocking rib 71 and a lower blocking rib 72 at both ends of the axial direction. The upper blocking rib 71 and the lower blocking rib 72 protrude toward both ends along the axial direction of the extrusion piece 7. The extrusion piece 7 is mounted on the juice squeezing barrel 4, and the extrusion piece 7 has a filtering position and a cleaning position on the juice squeezing barrel 4. In the filtering position, the extrusion piece 7 overlaps and fits with the adjacent extrusion pieces to form a juice outlet channel for filtering. When the extrusion piece 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 piece 7 from excessively rotating outward, thereby protecting the extrusion piece 7. When the squeezing sheet 7 is in the filtering position, the upper blocking ribs 71 and the lower blocking ribs 72 are in contact with the inner wall of the juice squeezing barrel 4, or a certain gap is provided between the upper blocking ribs 71 and the lower blocking ribs 72 and the side wall of the juice squeezing barrel 4. Only when the squeezing sheet is over-squeezed, the upper blocking ribs and the lower blocking ribs are in contact with the side wall of the juice squeezing barrel to provide protection.

[0066] Preferably, the inner sidewalls of the upper and lower blocking ribs 71 and 72 have the same shape as the inner sidewalls of the extrusion plate 7, so that when the extrusion plate 7 is rotated to the filtering position, the upper and lower blocking ribs 71 and 72 can perform normal filtering and extrusion functions. Of course, the inner wall of the juice squeezing barrel 4 can also be provided with grooves or depressions for accommodating the upper and lower blocking ribs, so that the inner wall of the juice squeezing barrel forms a complete wall surface.

[0067] The extrusion plate 7 is provided with an axial hole 73, through which the extrusion plate 7 is mounted on the juicing barrel to switch between a filtering position and a cleaning position. The extrusion plate 7 is also provided with an extrusion rib 74 toward the center of the juicing barrel. The extrusion rib 74 extends vertically and protrudes toward the center of the juicing barrel. When the screw is in operation, the extrusion rib cooperates with the screw to improve pulverization efficiency.

[0068] 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 barrel, for example, the gap of the upper blocking rib is smaller, while the gap of the lower blocking rib is larger. When the extrusion sheet is in the normal filtering position, the adjacent extrusion sheets fit together. When the excessive extrusion force applied to the extrusion sheet is small, the upper blocking rib fits with the inner wall of the juice barrel, while there is still a gap between the lower blocking rib and the inner wall; when the excessive extrusion force applied to the extrusion sheet is large, the lower blocking rib further fits with the inner wall of the juice barrel to withstand the excessive extrusion force at different stages, thereby forming different stages of protection for the extrusion sheet.

[0069] The above description is merely a preferred embodiment of the present invention and is not intended to limit the scope of implementation of the present invention. All equivalent changes and modifications made based on the present invention are covered by the scope of the claims of the present invention and will not be listed one by one here.
