Description

An easy-to-operate squeeze-type juicer Technical Field

[0001] This utility model relates to the field of food processing, and in particular to an extrusion juicer that uses screw extrusion to achieve juicing. Background Technology

[0002] Juicers use a screw extrusion mechanism to separate the juice from the pulp of food. The screw is typically set at a low speed to prevent oxidation of the juice, thus improving its texture. Current juicers usually use a filter screen or filter bars to separate the juice and pulp. However, filter screens are easily clogged by pulp during juice extraction, resulting in low efficiency and reduced juice yield. Therefore, technologies using filter screens are gradually being phased out.

[0003] Existing juicers typically use a combination of filter bars and a screw to extract juice. Two common filter bar filtration schemes exist in current technology. One scheme directly incorporates a filter bar structure within the juicing cylinder, creating filtration gaps between the bars. These gaps adapt to the pressure applied during extraction to meet varying juice yield requirements. The other scheme employs a detachable filter bar structure, such as two interlocking bars. Each bar assembly has spaced bars, and when interlocked, they form a juice channel between adjacent bars. This structure allows for easy cleaning by simply disassembling the two filter bar structures and utilizing the larger gaps between the bars.

[0004] However, existing grid structures still have the following technical problems: Whether it's the integrated grid structure of Scheme 1 or the interlocking grid structure, both require a juice outlet gap between adjacent grids. This gap is formed during product manufacturing and is easily affected by production processes, resulting in unstable and unreliable juice output. Simultaneously, the grids deform under screw pressure, widening the juice outlet gap. Especially under excessive pressure, an excessively large gap allows fruit pulp to flow out, affecting the purity of the juice and consequently its taste. Furthermore, in Scheme 1's integrated grid structure, fruit pulp remains within the juice outlet gaps, making cleaning inconvenient. While Scheme 2 partially solves the cleaning problem, users need to disassemble the juicing cylinder, clean each part separately, reassemble it, and connect it to the screw. There are even issues with achieving the preset installation position during self-assembly, affecting the normal operation of the juicing cylinder and causing operational inconvenience for users. Utility Model Content

[0005] The purpose of this invention is to provide a juicer that consistently preserves the pure taste of the juice, reduces user operation, and facilitates cleaning.

[0006] This utility model provides a convenient-to-operate squeeze-type juicer, including a main unit with an internal motor, a juice collection chamber disposed on the main unit, a detachable squeezing assembly disposed within the juice collection chamber, and a feeding cover covering the juice collection chamber. The squeezing assembly includes a screw and a squeezing cylinder sleeved on the screw. The squeezing cylinder includes a cylinder body and squeezing plates. The cylinder body is annular and sleeved on the screw. The squeezing plates are disposed at the lower end of the cylinder body and are rotatable along the axial direction. Multiple squeezing plates are arranged circumferentially and sleeved on the screw. The squeezing plates overlap and are attached to each other to form a juice outlet channel. The squeezing cylinder of this application has a cylinder body and squeezing plates. The cylinder body is sleeved on the screw and squeezes against the screw. Squeezing plates are disposed at the lower end of the cylinder body and are rotatable along the axial direction. Multiple squeezing plates are arranged circumferentially and overlapped. The juice outlet channel between the squeezing plates is used to form a juice outlet module sleeved on the screw. This design allows the extrusion plates to directly create the juice channel during juice extraction, relying solely on the screw's compression. Users don't need to adjust the juice gap manually. Furthermore, the juice gaps overlap and adhere tightly under screw pressure, preventing them from widening and affecting juice purity. For cleaning, the extrusion plates rotate on the juicing cylinder, increasing the space between the moving plates and facilitating the removal of fruit residue. This operation doesn't require disassembling the juicing cylinder; simply moving the corresponding extrusion plate simplifies the process. Resetting the extrusion plates also requires only a simple movement, or even automatic resetting by the screw's compression. It's important to note that this overlap refers to circumferential overlap between adjacent extrusion plates, not circumferential proximity. This ensures the inner extrusion plate adheres more tightly to the outer plate under pressure, preventing the juice channel from widening. Axial rotation here refers to the rotation center of the extrusion plate being in the same direction as the axis of the extrusion cylinder, but it does not mean that the axis of the extrusion plate is coincident with or completely parallel to the axis of the extrusion cylinder. The rotation axis of the extrusion plate and the center line of the extrusion cylinder may also be at a certain angle.

[0007] Preferably, the juicer cylinder further includes a retaining ring located at the lower end of the extrusion plate, and the lower end of the extrusion plate is rotatably connected to the retaining ring. Using the retaining ring to fix the bottom of the extrusion plate prevents deformation caused by the screw when the bottom of the extrusion plate is suspended in the air, thus increasing the strength of the filtration section of the juicer cylinder and ensuring the juice extraction effect.

[0008] Preferably, the extrusion plate has rotating shafts or shaft holes extending outwards at both ends, and the cylinder and fixing ring have corresponding shaft holes or rotating shafts. By providing rotating shafts or shaft holes at both axial ends of the extrusion plate, and corresponding shaft holes or rotating shafts in the cylinder and fixing ring, the extrusion plate can be directly clamped between the cylinder and fixing ring, and rotational installation is achieved through the cooperation of the rotating shafts and shaft holes, resulting in a simple structure. The rotating shafts and shaft holes are directly on the extrusion plate, cylinder, and fixing ring, ensuring a reliable structure and guaranteeing the strength requirements of the extrusion cylinder.

[0009] Preferably, the extrusion plate has an axially oriented through hole, and the extrusion cylinder further includes a rotating shaft. The rotating shaft passes through the through hole and is connected to the cylinder body and the fixing ring respectively. The extrusion plates rotate along the rotating shaft and overlap each other. By providing a through hole in the extrusion plate and a rotating shaft passing through the through hole and being fixedly connected to the cylinder body and the fixing ring at both ends respectively, the extrusion plate can rotate along the rotating shaft. The rotating shaft structure provides a more reliable installation position. Furthermore, the rotating shaft can be made of metal to further increase the strength of the rotating shaft and the extrusion plate, thereby improving the working reliability of the extrusion plate.

[0010] Preferably, a limiting groove and a limiting protrusion are provided between the bottom wall of the juice collecting chamber and the fixing ring. By providing the limiting groove and the limiting protrusion between the bottom wall of the juice collecting chamber and the fixing ring, the juicer can be more reliably installed on the bottom wall of the juice collecting chamber via the fixing ring. Furthermore, by placing the limiting groove and the limiting protrusion on the bottom wall, the juicer can be directly installed into place when it is installed from top to bottom. Simultaneously, the cooperating limiting groove and the limiting protrusion also limit the circumferential movement of the juicer, effectively preventing the juicer from rotating under the squeezing force of the screw, thus ensuring efficient juice extraction.

[0011] Preferably, the bottom of the juice collection chamber is provided with an annular positioning rib, and the bottom of the extrusion plate is inserted into the positioning rib and fixedly engaged with the juice collection chamber. By directly forming an annular positioning rib on the bottom wall of the juice collection chamber, the extrusion plate is directly inserted into the positioning rib to achieve engagement with the juice collection chamber. When extrusion is required, the upper end of the extrusion plate is fixedly connected to the cylinder, while the lower end is limited by the positioning rib, effectively preventing excessive extrusion when the lower end of the extrusion plate is suspended. When cleaning is required, the lower end of the extrusion plate is suspended, allowing the user to easily move the extrusion plate for cleaning, making it more convenient to use.

[0012] Preferably, a rotating shaft and a shaft hole are provided between the bottom wall of the juice collection chamber and the extrusion plate. By directly providing a rotating shaft and shaft hole between the bottom wall of the juice collection chamber and the extrusion plate, when the bottom end of the extrusion plate is positioned and engaged with the bottom wall of the juice collection chamber, it can also rotate under the pressure of the screw, thus better forming a juice outlet channel between adjacent extrusion plates. Furthermore, when the extrusion cylinder needs to be removed, the rotating shaft and shaft hole can be easily separated, making operation convenient.

[0013] Preferably, the juicer cylinder is provided with a limiting structure that prevents the extrusion plate from rotating outward. By providing the limiting structure, when the extrusion plate is subjected to excessive extrusion force, the limiting structure can ensure that the extrusion plate is in a reasonable position and prevent damage to the extrusion plate due to excessive extrusion.

[0014] Preferably, the limiting structure includes a limiting platform disposed on the juicer cylinder, which can block the extrusion plate when it rotates outward. The limiting structure is configured as a limiting platform, directly blocking the extrusion plate; this design is simple and effectively blocks the extrusion plate. Furthermore, the limiting platform can be directly mounted on the juicer cylinder, eliminating the need for other separate structures, making implementation convenient and requiring no additional action during use, resulting in faster and more convenient operation.

[0015] Preferably, the limiting structure includes blocking ribs disposed at both axial ends of the extrusion plate, the blocking ribs being able to conform to the inner wall of the juice extraction cylinder to block the extrusion plate. Blocking ribs protruding axially are provided at both axial ends or one end of the extrusion plate, extending upwards or downwards from the axial ends of the extrusion plate. Thus, when the extrusion plate is in the filtering position and is compressed by the screw, the extrusion ribs can directly conform to the inner wall of the juice extraction cylinder, producing a blocking effect.

[0039] Example 1

[0040] As a first embodiment of the convenient-to-operate squeeze-type juicer of this utility model, as shown in Figures 1-9, the juicer includes a main unit (not shown), a juice collection chamber 2, a squeezing assembly, and a feeding cover 1. The main unit is equipped with a motor (not shown). The juice collection chamber 2 is detachably mounted on the main unit. The squeezing assembly is located inside the juice collection chamber. The squeezing assembly includes a screw 3 and a squeezing cylinder 4. The squeezing cylinder 4 is sleeved outside the screw 3. The feeding cover 1 covers the top of the juice collection chamber 2 to close the upper opening of the juice collection chamber 2. Food is fed in through the opening of the feeding cover 1 and falls into the squeezing assembly. The screw 3 is driven to rotate by the motor, squeezing, cutting, and grinding the food between the screw 3 and the squeezing cylinder 4 to fully pulverize the food. The juice collection chamber 2 is provided with a pulp outlet 21 and a juice outlet 22. The juice is collected in the juice collection chamber 2 after being filtered by the squeezing cylinder 4 and discharged through the juice outlet 22. At the same time, the pulp also accumulates in the juice collection chamber 2 and is discharged through the pulp 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 part and is integrally formed with the screw body 31, and the screw teeth 33 are disposed on the outer surface of the screw body 31.

[0041] As shown in Figures 3-5, the juice extraction cylinder 4 includes a cylinder body 41 and extrusion plates. The cylinder body 41 is sleeved on the upper end of the screw 3. The extrusion plates are located at the lower end of the cylinder body 41 and are multiple in number. Preferably, the extrusion plates include alternately arranged movable extrusion plates 42 and fixed extrusion plates 43. The fixed extrusion plates 43 are integral with the cylinder body 41 or are fixedly connected to the cylinder body 41. The movable extrusion plates 42 are rotatably disposed at the lower end of the cylinder body 41. Multiple movable extrusion plates 42 and fixed extrusion plates 43 are arranged circumferentially at the lower end of the cylinder body 41. When the movable extrusion plates 42 rotate and overlap with the fixed extrusion plates 43, the movable extrusion plates 42 and the fixed extrusion plates 43 form a ring and are sleeved on the lower end of the screw 3. Juice channels 5 are sequentially formed between the movable extrusion plates 42 and the fixed extrusion plates 43 to achieve the function of filtering juice. When the juicer 4 needs cleaning, the user can move the movable squeezing plate 42 to disengage it from the fixed squeezing plate 43, as shown in Figure 5, thus opening the juice outlet channel 5. In this way, the fruit residue and other residues remaining in the juice outlet channel 5 can be easily cleaned, achieving convenient cleaning of the juicer.

[0042] The cylinder 41 has auxiliary filter holes 40 on its side wall. When the screw 3 is engaged with the extrusion section of the cylinder 41, a portion of the juice produced by the extrusion can be discharged through the auxiliary filter holes 40. This prevents the juice from being discharged from the filtration section due to excessive juice volume, which would prevent the juice from being effectively discharged and instead be carried out of the residue outlet by the pulp. The inner side wall of the cylinder 41 is also provided with squeezing ribs 45. The squeezing ribs 45 can be provided only in the extrusion section, or they can extend downwards from the extrusion section to the filtration section. The squeezing ribs 45 can cooperate with the screw 3 to reduce the gap between the screw 3 and the inner wall of the squeezing cylinder 4, thereby improving the extrusion and crushing efficiency of the extrusion assembly and increasing the juice yield.

[0043] Preferably, as shown in Figures 6-9, the juicer cylinder 4 further includes a retaining ring 44 located at the lower end of the squeezing plate. The lower end of the retaining squeezing plate 43 is provided with a retaining groove 431, and the retaining ring 44 is provided with a corresponding boss 442. The retaining ring 44 is fixedly connected to the lower end of the retaining squeezing plate 43 via the boss 442 and the retaining groove 431. The lower end of the cylinder body 41 located between the retaining squeezing plates 43 is provided with an upper shaft hole 62, and the retaining ring is provided with a lower shaft hole 63. The movable squeezing plate 42 has rotating shafts 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 lock the movable squeezing plate 42 between the cylinder body 41 and the retaining ring 44, and the movable squeezing plate 42 can rotate along the rotating shaft 61. By setting an annular fixing ring 44, the lower ends of the movable extrusion plate 42 and the fixed extrusion plate 43 are limited, which prevents the extrusion plate from being deformed by excessive extrusion from the screw when the lower end is suspended, thereby improving the strength of the extrusion plate and ensuring the normal operation of the juicer.

[0044] The bottom wall of the juice collection chamber 2 is provided with an annular positioning rib 23. The juice squeezing cylinder 4 can be inserted into the positioning rib 23 through the fixing ring 44 to fix the juice squeezing cylinder 4 and the juice collection chamber 2 at the bottom end. The bottom wall of the juice collection chamber 2 is also provided with a central boss 26, which 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 collection chamber 2 into a juice outlet portion located outside the positioning rib 23 and a residue outlet portion located inside the positioning rib 23. The juice outlet portion is connected to the juice outlet 22, and the residue outlet portion is connected to the residue outlet 21. The side wall of the positioning rib 23 is also provided with a juice discharge groove 24, which can discharge the juice flowing out of the filter section to the juice outlet portion.

[0045] Preferably, the juicing cylinder 4 is further provided with a limiting structure to prevent the rotation of the extrusion plate. The limiting structure includes a lower limiting platform 443 disposed on the fixed ring 44. When the movable extrusion plate 42 rotates to the filtering position, the movable extrusion plate 42 overlaps and fits with the adjacent fixed extrusion plate 43. When the movable extrusion plate 42 is pushed and squeezed by the screw, especially when processing hard ingredients, the movable extrusion plate is prone to excessive deformation due to excessive extrusion force. Although the outer fixed extrusion plate can withstand a certain amount of extrusion force and maintain the gap of the juice channel, when the movable extrusion plate and the fixed extrusion plate are continuously squeezed, they will deform outward and increase the gap between the inner wall of the juicing cylinder and the screw, thereby reducing the grinding and pulverizing efficiency of the extrusion assembly. The lower limiting platform is provided to prevent the movable extrusion plate from rotating outward and to withstand the extrusion force of the movable extrusion plate, which can protect the movable extrusion plate and the fixed extrusion plate, effectively ensuring that the movable extrusion plate and the fixed extrusion plate are always in the preset state, maintaining the grinding and pulverizing efficiency of the extrusion assembly, and thus ensuring the normal processing of the juicer. The extrusion plate can be switched between the filtering and cleaning positions simply by rotating it. Therefore, the extrusion plate usually only needs to rotate within a certain angle, rather than being set to rotate a full circle. The limiting structure is usually used to protect the extrusion plate and prevent it from being excessively squeezed. Therefore, the limiting structure is usually set at the edge or periphery of the rotation range of the extrusion plate. That is, when the extrusion plate rotates to the filtering position, the limiting structure is inactive or just barely in contact with the plate. In this way, the limiting structure can fully protect the extrusion plate.

[0046] The movable extrusion plate 42 includes a body 421 and an adhesive portion 422. The rotating shaft 61 extends outward from both ends of the body 421, such that the axis of the extrusion plate passes through the body 421. The adhesive portion 422 extends radially outward from the body 421, that is, it extends outward in a section perpendicular to the axis of the movable extrusion plate 42. When the movable extrusion plate 42 and the fixed extrusion plate 43 are assembled sequentially, the adhesive portion 422 is located inside the fixed extrusion plate 43. When the screw 3 is working, it pushes the material and further pushes the adhesive portion 422 to rotate outward so that it overlaps and adheres to the fixed extrusion plate 43, forming a juice channel 5 between adjacent extrusion plates.

[0047] Preferably, the inner wall of the fitting portion 422 is further provided with extrusion ribs 423. The extrusion ribs 423 extend axially along the juicer cylinder 4 and protrude toward the center of the juicer cylinder 4 to engage with the screw 3, thereby improving the grinding efficiency between the screw 3 and the juicer cylinder 4. The outer wall of the fitting portion 422 is further provided with filter ribs 425. When the movable extrusion plate 42 and the fixed extrusion plate 43 are in contact, the filter ribs 425 are in contact with the fixed extrusion plate 43, and a juice outlet groove 426 is formed between the filter ribs 425. The gaps between the filter ribs 425 and the juice outlet groove 426 together constitute the juice outlet channel 5. By using the filter ribs 425 to form the juice outlet groove 426 and further form the juice outlet channel, the juice outlet area of ​​the juice outlet channel can be increased, thereby improving the juice extraction efficiency of the juicer cylinder. Since the movable extrusion plate can rotate during screw extrusion and make adjacent extrusion plates fit together, and even when the movable extrusion plate is subjected to a large extrusion force, the suspended juice outlet section will also deform to reduce the gap of the juice outlet, thereby reducing the area of ​​the juice outlet channel and improving the taste of the juice. This is because, for different processed ingredients, such as soft ingredients like watermelon, the juice yield is high, requiring rapid juice extraction. Therefore, a larger juice extraction channel is needed. Due to the softness of the ingredients, the screw applies less pressure to the movable extrusion plate through the ingredients, increasing the juice extraction channel area between the movable and fixed extrusion plates, thus ensuring efficient juice extraction and rapid juice discharge. Conversely, for hard ingredients like carrots, the juice yield is lower and they contain more pulp and fiber. The screw applies greater pressure to the movable extrusion plate through the ingredients, effectively squeezing and adhering the movable and fixed extrusion plates together. By reducing the area of ​​the juice extraction channel, pulp is prevented from being discharged through the channel, preserving the juice's texture. The relatively lower juice yield of these ingredients also meets the speed requirements for juice extraction.

[0048] Preferably, when the movable extrusion plate 42 rotates to overlap and fit the fitting portion 422 with the adjacent fixed extrusion plate 43, the body 421 is also in an overlapping and fitting state with the adjacent fixed extrusion plate 43 on the other side. This forms juice outlet channels on both the upstream and downstream sides of the extrusion plate, thereby improving juice extraction efficiency. The side wall of the body 421 that fits with the adjacent fixed extrusion plate 43 is also provided with support ribs 4211, and an outflow juice groove 4212 is formed between the support ribs 4211. The outflow juice groove 4212 and the gap between the body 421 and the fixed extrusion plate 43 together constitute the juice outlet channel 5.

[0049] Preferably, the fixed extrusion plate 43 extends circumferentially in the transverse cross-section of the juicer cylinder 4. The inner wall of the upstream end of the fixed extrusion plate 43 is provided with a mounting portion 432, which is recessed outward along the inner wall of the fixed extrusion plate 43. The fitting portion 422 fits onto the mounting portion 432. Thus, when the movable extrusion plate 42 and the fixed extrusion plate 43 are in contact, their inner walls are located on the same circumference. Here, "same circumference" means that the inner walls of the movable extrusion plate 42 and the fixed extrusion plate 43 have the same radius in the transverse cross-section of the juicer cylinder, so that the movable extrusion plate and the fixed extrusion plate are in the same processing state when they are rotated and ground by the screw 3. It should be noted that "same circumference" means that, ideally, the two are located on the same circumference within an acceptable tolerance range. The upstream end, as defined here, is the end that first contacts a specific point on the screw, based on the direction of screw rotation. The downstream end is the end that subsequently contacts that specific point on the screw.

[0050] It should be noted that, as shown in Figure 4, the overlapping and fitting of the extrusion plates defined in this utility model refers to the overlapping portion of adjacent extrusion plates in the radial direction, that is, one extrusion plate is located on the outer side and the other adjacent extrusion plate is located on the inner side. The juice outlet channel formed in this way has a channel portion extending circumferentially. The advantage of this setting is that when the movable extrusion plate is rotated by the extrusion force of the screw, the movable extrusion plate moves outward and continuously fits with the adjacent fixed extrusion plate, ensuring that the juice outlet channel 5 located between the two extrusion plates is always under the effect of pre-tightening pressure to ensure the preset gap size, and unlike the existing grid bars, the gap will not become larger when squeezed, causing fruit pulp to be discharged from the gap. Therefore, the solution of this application can always maintain the purity of the juice, making the juice of the juicer taste better. Even if the squeezing plates deform somewhat during prolonged use, the movable squeezing plate can still maintain its contact with the fixed squeezing plate under the squeezing force of the screw, thus ensuring the integrity of the juice channel and controllable gaps. Unlike existing grids that deform over time and affect the normal juice output of the juicer, the juicer of this application maintains a consistent juice taste throughout its product lifecycle. When cleaning the juice cylinder is required, the movable squeezing plate can be moved to the cleaning position, separating it from the fixed squeezing plate, as shown in Figure 5. At this time, the juice channel between the two adjacent squeezing plates is fully opened, and the fruit pulp remaining in the juice channel can be easily cleaned. This design, by changing the juice channel from being located between two circumferential grids to being located between two radial squeezing plates, breaks the contradiction between existing grids, thus maintaining the juice taste and efficiency of the juice cylinder and facilitating normal cleaning of the juice cylinder.

[0051] By configuring the extrusion plates, which are rotatable along the axial direction, the extrusion plates can perform different functions at different positions. This allows for different functions, such as a filtering position formed when the extrusion plates overlap and a cleaning position when the juice outlet channel is opened by moving the extrusion plates. This utilizes the inherent structure of the juicer cylinder to achieve these different functions, overcoming the contradictions of existing grid-based solutions, changing both the juice outlet and cleaning methods. This improves juice outlet efficiency, facilitates cleaning of the juicer cylinder, and simultaneously meets the various needs of the juicer cylinder.

[0052] Understandably, the active extrusion sheet and the fixed extrusion sheet are set to the same shape and are distributed circumferentially along 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 together.

[0053] Understandably, the juice extraction cylinder can be directly inserted into the bottom wall of the juice collection chamber via the extrusion plate without the fixing ring.

[0054] Understandably, the extrusion plate has a protruding baffle in the axial direction, which can fit against the inner wall of the extrusion cylinder. When the extrusion plate is excessively deformed by the push of the screw, the baffle can prevent the extrusion plate from being excessively deformed to protect the extrusion plate.

[0055] Understandably, the extrusion rib may have an extrusion groove on its inner wall that cooperates with the screw, thereby improving the cutting effect and extracting the juice.

[0056] Example 2

[0057] As a second embodiment of the easy-to-operate squeeze-type juicer described in this utility model, as shown in Figures 10-12, compared with the first embodiment, the squeeze plates in this embodiment are all set as movable squeeze plates.

[0058] As shown in Figures 10-12, the extrusion section 4 includes a cylinder 41 and multiple movable extrusion plates 42. The movable extrusion plates 42 are arranged circumferentially along the juice extrusion cylinder 4, and the movable extrusion plates 42 can rotate axially to have a filtering position as shown in Figure 11 and a cleaning position as shown in Figure 12. When the screw 3 rotates, the screw 3 pushes the food and further pushes the movable extrusion plates 42 to rotate, and overlaps and fits with adjacent movable extrusion plates 42 to form a juice outlet channel 5 between adjacent movable extrusion plates 42, so that the movable extrusion plates 42 perform the function of juice extrusion. When it is necessary to clean the juice extrusion cylinder 4, the movable extrusion plates 42 are moved to the cleaning position to open the juice outlet channel, making it easy to clean the fruit residue and other residues remaining in the juice outlet channel.

[0059] The movable extrusion plate 42 includes a body 421 and a fitting portion 422. The body 421 has a through hole 4213. The juice extraction cylinder 4 also includes a rotating shaft 64 passing through the through hole 4213. Preferably, the rotating shaft 64 is a metal shaft to improve its strength. The rotating shaft 64 passes through the through hole 4213 to be fixedly connected to the body 421. Preferably, the juice extraction cylinder 4 also includes a fixing ring 44 disposed at the bottom end of the movable extrusion plate 42. Preferably, the body 421 has an upper shaft hole, the fixing ring 44 has a lower shaft hole, and both ends of the rotating shaft 64 are fixedly connected to the upper shaft hole and the lower shaft hole respectively to clamp the movable extrusion plate 42 between the body 421 and the fixing ring 44.

[0060] The juicer cylinder 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 disposed on the inner side wall of the lower end of the body 421, and the lower limiting platform 443 is disposed on the inner side wall of the upper end of the fixing ring 44. The two axial ends of the fitting part 422 are provided with baffles 4221. When the movable extrusion plate 42 is pushed outward by the screw, the baffles 4221 can fit against the upper limiting platform 411 and the lower limiting platform 443 respectively. Preferably, when the fitting portion 422 is in contact with the adjacent movable extrusion plate 42, the baffle 4221 does not contact the upper limit platform 411 and the lower limit platform 443. Only when the movable extrusion plate 42 is subjected to a large extrusion force does the baffle 4221 engage with the upper limit platform 411 and the lower limit platform 443 to prevent the movable extrusion plate 42 from being excessively extruded and deformed. By setting the limiting structure, excessive deformation can be avoided when the extrusion point is subjected to excessive extrusion, ensuring that the extrusion plate is always in a preset changing state. This guarantees the normal and efficient juice extraction of the extrusion plate and also allows for easy switching to a cleaning position to clean the juice extraction cylinder.

[0061] Multiple movable extrusion plates are provided. During operation, these plates are pushed by a screw (the screw and the plates are not in direct contact; the screw pushes the food, which in turn pushes the plates; the screw provides the power source and ultimately drives the plates). Adjacent plates overlap and form juice channels at their contact points. This eliminates the need to set gaps between the juice channels during the juicing process and avoids fatigue deformation caused by the plates constantly bearing pressure when fixed. This ensures the juice channels remain within a preset gap size, guaranteeing pure juice and improving the taste of the juice. Furthermore, the movable plates can easily detach from the juice outlet, allowing the juice channels to be fully opened for quick and easy cleaning. Furthermore, the movable extrusion plate is fixed on the juicer body, eliminating the need for the user to disassemble it. This is especially convenient for maintaining the juice output channel position; simply installing the screw in place allows for efficient juice output under its push, making it more convenient and faster to use.

[0062] It is understandable that the juice extraction cylinder may not have the fixing ring, and the bottom end of the movable juice extraction cylinder may be directly fixed to the bottom wall of the juice collection chamber.

[0063] Understandably, the retaining ring can be configured as a metal component integral with the rotating shaft. Specifically, the retaining ring is annular, and the rotating shaft is fixed to the annular retaining ring, for example, by welding them together. The movable extrusion piece is fixedly connected to the main body via the retaining ring and the rotating shaft.

[0064] Understandably, the body and the fixing ring are respectively provided with protrusions. 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.

[0065] Example 3

[0066] As a third embodiment of the easy-to-operate squeeze-type juicer described in this utility model, as shown in Figure 13, compared with the first embodiment, the limiting structure in this embodiment includes a blocking rib disposed on the squeeze plate.

[0067] As shown in Figure 13, the extrusion plate 7 has an upper blocking rib 71 and a lower blocking rib 72 at both ends in the axial direction. The upper blocking rib 71 and the lower blocking rib 72 protrude from both ends along the axial direction of the extrusion plate 7. The extrusion plate 7 is installed on the juice extraction cylinder 4, and the extrusion plate 7 has a filtering position and a cleaning position on the juice extraction cylinder 4. In the filtering position, the extrusion plate 7 overlaps and fits with the adjacent extrusion plate to create a juice outlet channel for filtering. When the extrusion plate 7 is over-extruded, the upper blocking rib 71 and the lower blocking rib 72 fit against the inner wall of the juice extraction cylinder 4 to prevent the extrusion plate 7 from rotating excessively outward, thereby protecting the extrusion plate 7. When the extrusion plate 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 extraction cylinder 4, or there is a certain gap between the upper blocking rib 71 and the lower blocking rib 72 and the side wall of the juice extraction cylinder 4. Only when the extrusion plate is over-extruded will the upper blocking rib and the lower blocking rib be in contact with the side wall of the juice extraction cylinder to play a protective role.

[0068] Preferably, the inner walls of the upper blocking rib 71 and the lower blocking rib 72 have the same shape as the inner wall of the extrusion plate 7, so that when the extrusion plate 7 is rotated to the filtering position, the upper blocking rib 71 and the lower blocking rib 72 can perform normal filtering and extrusion functions. Of course, the inner wall of the juice extraction cylinder 4 can also be provided with grooves or countersunk platforms for accommodating the upper and lower blocking ribs, so that the inner wall of the juice extraction cylinder forms a complete wall surface.

[0069] The extrusion plate 7 is provided with a shaft hole 73, and the extrusion plate 7 is mounted on the juice extraction cylinder through the shaft hole 73 to switch between a filtering position and a cleaning position. The extrusion plate 7 is also provided with an extrusion rib 74 facing the center of the juice extraction cylinder. The extrusion rib 74 is arranged vertically and protrudes towards the center of the juice extraction cylinder. When the screw is in the extrusion operation, the extrusion rib can cooperate with the screw to improve the crushing efficiency.

[0070] Understandably, the upper and lower blocking ribs can also be configured to have different gaps with the sidewall of the squeezing cylinder. For example, the gap of the upper blocking rib is smaller, while the gap of the lower blocking rib is larger. When the squeezing plate is in the normal filtering position, the adjacent squeezing plates are in contact with each other. When the excessive squeezing force on the squeezing plate is small, the upper blocking rib is in contact with the inner wall of the squeezing cylinder, while the lower blocking rib still has a gap with the inner wall. When the excessive squeezing force on the squeezing plate is large, the lower blocking rib is further in contact with the inner wall of the squeezing cylinder to withstand the excessive squeezing force at different stages, thereby providing protection for the squeezing plate at different stages.
