Juicer

Abstract

This application discloses a juicer, including a cup body, a screw press, and a power output component. The cup body has a feeding chamber and a juicing chamber connected sequentially from top to bottom. The screw press is rotatably disposed within the juicing chamber. The power output component has a transmission connection part. The transmission connection part is connected to the screw press, and the maximum outer diameter of the connection point between the transmission connection part and the screw press is greater than half the minimum inner diameter of the juicing chamber. This maximum outer diameter ensures better perpendicularity between the transmission connection part and the screw press (i.e., coaxiality), effectively improving the axial stability of the screw press and preventing eccentric movement during rotation that could damage surrounding structural components such as the cup body.

Description

Technical Field

[0001] This application relates to the field of juicer technology, and more particularly to a juicer. Background Technology

[0002] A juicer is a machine that can quickly extract juice from fruits and vegetables. It can juice a variety of different kinds of fruits and vegetables and allows users to choose according to their preferences. However, in existing juicers, the transmission connection between the power shaft and the screw press is often not accurately positioned, making the axial operation of the screw press unstable. This causes the screw press to easily move eccentrically during rotation, potentially touching or even damaging surrounding structural components such as the cup. Summary of the Invention

[0003] Therefore, it is necessary to provide a juicer in which the relative positions of the transmission connection and the screw press are reliably positioned.

[0004] A juicer, comprising:

[0005] The cup body has a feeding chamber and a juicing chamber connected sequentially from top to bottom.

[0006] A screw press is rotatably mounted within the juicing chamber; and

[0007] A power output assembly having a transmission connection portion connected to the screw press, wherein the maximum outer diameter of the connection between the transmission connection portion and the screw press is greater than half the minimum inner diameter of the juicing chamber.

[0008] In one embodiment, the maximum outer diameter of the connection between the drive connection and the screw press is ≥25mm.

[0009] In one embodiment, an axial limiting structure is provided between the transmission connection and the screw press, the axial limiting structure being used to restrict the axial movement of the screw press.

[0010] In one embodiment, the axial limiting structure includes a retaining rib and a retaining groove. One of the transmission connection and the screw press is provided with the retaining rib, and the other of the transmission connection and the screw press is provided with the retaining groove. The retaining rib is engaged in the retaining groove to restrict the axial movement of the screw press.

[0011] In one embodiment, a first seal is provided between the drive connection and the screw press.

[0012] In one embodiment, the power output assembly includes a power shaft, the transmission connection includes a rotating cylinder and a connecting column coaxially arranged, the rotating cylinder has a receiving cavity, the connecting column is connected to the top end of the receiving cavity and extends toward the bottom end of the receiving cavity, the rotating cylinder is connected to the screw press, and the power shaft is connected to the connecting column.

[0013] In one embodiment, the rotating cylinder is a hollow structure with a closed top and an open bottom, and the bottom end of the connecting column extends to the outside of the receiving cavity; and / or

[0014] One end of the power shaft is fitted inside the connecting column, and the cross-sectional shape of the end of the power shaft that connects to the connecting column is polygonal.

[0015] In one embodiment, the power output component includes a motor and a reduction component. The reduction component includes a gearbox and a gear assembly. The gear assembly is movably disposed within the gearbox. The motor is connected to the gearbox and is drivenly connected to the input end of the gear assembly. The transmission connection is drivenly connected to the output end of the gear assembly.

[0016] In one embodiment, the power output assembly includes a power shaft, and the transmission connection includes a first rotating cylinder and a second rotating cylinder connected sequentially from bottom to top. A connection is also provided at the connection between the first rotating cylinder and the second rotating cylinder. The first rotating cylinder is sleeved on the outside of the gearbox, and the second rotating cylinder is connected to the screw press. One end of the power shaft is connected to the output end of the gear assembly, and the other end of the power shaft is connected to the connection.

[0017] In one embodiment, the bottom end of the screw press is further provided with a first limiting part, which can cooperate with the cup body to limit the axial movement of the screw press.

[0018] The juicer provided in this application has a power output component that can drive a screw press to rotate via a transmission connection, so that the screw press, in conjunction with the cup body, presses the ingredients put into the cup body to achieve juicing. Since the maximum outer diameter of the connection between the transmission connection and the screw press is greater than half of the minimum inner diameter of the juicing chamber, the above structure has at least the following beneficial effects:

[0019] 1) When the juicer's working screw press is subjected to lateral extrusion force, the transmission connection and the screw press can better maintain perpendicularity (i.e., the coaxiality of the transmission connection and the screw press) to ensure that the screw press will not move eccentrically, thereby avoiding damage to the screw press itself and its surrounding components such as the cup.

[0020] 2) As can be seen from the torque formula, torque = force * lever arm. When the torque is constant, the larger the lever arm, the smaller the force required. Therefore, when the axial load of the screw press is constant, the larger the diameter of the connection between the transmission connection and the screw press, the smaller the power required. This not only makes the connection between the transmission connection and the screw press more stable, but also reduces the force on the transmission anti-rotation position of the transmission connection and the screw press, making it more stable. This results in a longer lifespan for the screw press and the transmission connection, and makes it less likely for the two to seize up.

[0021] 3) For the same material and structure, the larger the part size, the better the strength. Therefore, limiting the maximum outer diameter of the connection between the transmission connection and the screw press to be greater than half the minimum inner diameter of the juicing chamber can effectively ensure the structural strength of the screw press and extend its service life.

[0031] like Figures 1 to 3 As shown, this application provides a juicer 10, which includes a cup body 100, a screw press 200, and a power output component 300. The cup body 100 is provided with a feeding chamber 132 and a juicing chamber 142 connected sequentially from top to bottom. The screw press 200 is rotatably disposed in the cup body 100. The power output component 300 has a transmission connection part 400, which is connected to the screw press 200. The maximum outer diameter of the connection between the transmission connection part 400 and the screw press 200 is greater than half of the minimum inner diameter of the juicing chamber 142. The power output component 300 is used to drive the screw press 200 to rotate through the transmission connection part 400, so that the screw press 200 cooperates with the cup body 100 to press the ingredients put into the cup body 100 to achieve juicing.

[0032] The juicer 10 provided in this application has a power output component 300 that can drive the screw press 200 to rotate via the transmission connection part 400, so that the screw press 200 cooperates with the cup body 100 to press the ingredients put into the cup body 100 to achieve juicing. Since the maximum outer diameter of the connection between the transmission connection part 400 and the screw press 200 is greater than half of the minimum inner diameter of the juicing chamber 142, the above structure has at least the following beneficial effects:

[0033] 1) When the juicer 10 is working and the screw press 200 is subjected to lateral extrusion force, the transmission connection 400 and the screw press 200 can better maintain perpendicularity (i.e., the coaxiality of the transmission connection 400 and the screw press 200) to ensure that the screw press 200 will not move eccentrically, thereby avoiding damage to the screw press 200 itself and its surrounding components such as the cup body 100.

[0034] 2) As can be seen from the torque formula, torque = force * lever arm. When the torque is constant, the larger the lever arm, the smaller the force required. Therefore, when the axial load of the screw press 200 is constant, the larger the diameter of the connection between the transmission connection 400 and the screw press 200, the smaller the power required. This not only makes the connection between the transmission connection 400 and the screw press 200 more stable, but also makes the transmission anti-rotation position of the transmission connection 400 and the screw press 200 less stressed and more stable, which makes the screw press 200 and the transmission connection 400 have a longer service life and the two are less likely to seize up.

[0035] 3) For the same material and structure, the larger the part size, the better the strength. Therefore, the size limitation that the maximum outer diameter of the connection between the transmission connection part 400 and the screw press 200 is greater than half the minimum inner diameter of the juicing chamber 142 can effectively ensure the structural strength of the screw press 200 and extend its service life.

[0036] It should be noted that the connection between the transmission connection part 400 and the screw press 200 described in this application can be understood as the position where the transmission connection part 400 and the screw press 200 come into contact with each other during the operation of the juicer 10. When the two come into contact with each other, a connection effect is formed.

[0037] In one embodiment, the screw press 200 has an internal receiving cavity 210, and the transmission connection 400 is disposed within the receiving cavity 210. Specifically, the transmission connection 400 extends into the receiving cavity 210, which can effectively increase the axial length of the connection between the transmission connection 400 and the screw press 200, increase the force-bearing area of ​​the screw press 200, and make the operation of the screw press 200 more stable.

[0038] In some other embodiments, the structure of the receiving cavity 210 of the screw press 200 can be omitted, that is, the end face of the screw press 200 is directly connected to the end face of the transmission connection part 400, as long as the maximum outer diameter of the connection between the transmission connection part 400 and the screw press 200 is greater than half of the minimum inner diameter of the juicing cavity 142, and no unique limitation is made here.

[0039] In one embodiment, the maximum outer diameter D1 of the connection between the transmission connection 400 and the screw press 200 is ≥25mm, ensuring reliable relative positioning of the transmission connection 400 and the screw press 200, thereby effectively improving the axial operational stability of the screw press 200. D1 is preferably 25mm, 40mm, or 65mm. Preferably, the transmission connection 400, the power shaft 310, and the screw press 200 are coaxially arranged.

[0040] like Figure 2As shown, the power output assembly 300 includes a motor 320 and a reduction assembly 330. The reduction assembly 330 includes a gearbox 331 and a gear assembly 332. The gear assembly 332 is movably disposed within the gearbox 331. The motor 320 is connected to the gearbox 331 and is drivenly connected to the input end of the gear assembly 332. The transmission connection part 400 is drivenly connected to the output end of the gear assembly 332. By setting the reduction assembly 330, the power output assembly 300 can achieve the effect of speed reduction and torque increase, thereby improving the pressing force of the screw press 200 and improving the juicing effect of the juicer 10.

[0041] The inner wall of the gearbox 331 is provided with an internal gear ring 333. The gear assembly 332 includes a planet carrier 334, a sun gear, and multiple planetary gears 335. The sun gear is connected to one side of the planet carrier 334. The planetary gears 335 are rotatably connected to the planet carrier 334 and mesh with the internal gear ring 333. The multiple planetary gears 335 are evenly arranged along the circumference of the planet carrier 334, and are located on the side of the planet carrier 334 away from the sun gear. The transmission connection part 400 is connected to the sun gear. The motor 320 includes a drive gear 322 and a rotary drive member 321. The drive gear 322 is connected to the output end of the rotary drive member 321 and meshes with the planetary gears 335. Specifically, when the rotary drive member 321 outputs power through the drive gear 322, the drive gear 322 can mesh with the planetary gears 335 of the reduction assembly 330 and drive the planet carrier 334 to rotate, thereby driving the sun gear to rotate, thus achieving the reduction effect of the reduction assembly 330. Figure 1 As shown, an axial limiting mechanism 500 is provided near the transmission connection part 400. The axial limiting mechanism 500 is used to limit the axial movement of the transmission connection part 400, prevent the transmission connection part 400 from eccentric movement during rotation, ensure the reliable positioning of the transmission connection part 400, and ensure the axial rotational stability of the transmission connection part 400, so as to make the transmission connection part 400 more accurate and longer-lasting.

[0042] like Figure 3 and Figure 4 As shown, optionally, the power output assembly 300 includes a power shaft 310, and the transmission connection part 400 includes a rotating cylinder 450 and a connecting post 460 coaxially arranged. The rotating cylinder 450 has a receiving cavity 452, and the connecting post 460 is connected to the top end of the receiving cavity 452 and extends towards the bottom end of the receiving cavity 452. The rotating cylinder 450 is connected to the screw press 200, and the power shaft 310 is connected to the connecting post 460. Specifically, the rotating cylinder 450 is a hollow structure with a closed top and an open bottom. The rotating cylinder 450 is sleeved in the receiving cavity 210, and the bottom end of the connecting post 460 extends to the outside of the receiving cavity 452. The rotating cylinder 450 and the connecting post 460 are integrally formed.

[0043] like Figure 4 As shown, the axial limiting mechanism 500 includes a first limiting member 510, which is sleeved within the receiving cavity 452 to limit the axial movement of the transmission connection part 400. The first limiting member 510 is a fixed component, while the transmission connection part 400 is a rotatable moving component. The first limiting member 510 can abut against the inner wall of the receiving cavity 452, thereby providing axial positioning for the transmission connection part 400 and preventing eccentric movement during rotation. This results in higher precision, more stable operation, and longer service life for the transmission connection part 400. Furthermore, the positioning of the moving component transmission connection part 400 by the fixed component first limiting member 510 is more reliable, leading to more stable operation.

[0044] In an optional embodiment, the first limiting member 510 is axially arranged around the connecting post 460, and the first limiting member 510 extends from the inner side of the bottom end of the cup body 100 toward the top end of the cup body 100.

[0045] Furthermore, the axial limiting mechanism 500 also includes a second limiting member 520, which is disposed at the bottom end of the connecting column 460 to limit the axial movement of the transmission connection part 400, thereby further enhancing the axial positioning effect of the transmission connection part 400, making the transmission connection part 400 more accurate, more stable in operation, and longer in service life.

[0046] The axial limiting mechanism 500 also includes a first bearing 530, which is sleeved on the outside of the connecting column 460 and disposed between the connecting column 460 and the first limiting member 510. The first bearing 530 is mainly used to limit the rotation center of the transmission connection part 400 and prevent the transmission connection part 400 from moving along its own axial direction during rotation.

[0047] The axial limiting mechanism 500 also includes a second bearing 540, which is sleeved on the outside of the connecting column 460 and positioned between the first bearing 530 and the second limiting member 520. When the transmission connection part 400 rotates and moves upward along its own axial direction, the second bearing 540 can separate the first bearing 530 and the second limiting member 520, preventing direct contact between them. This solves problems such as reduced durability, noise, vibration, and heat generation caused by friction between the first bearing 530 and the second limiting member 520.

[0048] Preferably, the second bearing 540 is a planar bearing. When the transmission connection part 400 moves upward along its own axis during rotation, the planar bearing located between the first bearing 530 and the second limiting member 520 can change the sliding friction between the first bearing 530 and the second limiting member 520 into rolling friction, so that the first bearing 530 and the second limiting member 520 have less wear and longer service life.

[0049] One end of the power shaft 310 is fitted inside the connecting post 460. The cross-sectional shape of the end of the power shaft 310 that abuts the connecting post 460 is polygonal, so as to restrict the rotation of the connecting post 460 relative to the power shaft 310 and improve the connection stability between the power shaft 310 and the connecting post 460.

[0050] The maximum inner diameter d1 at the junction of the receiving cavity 452 and the first limiting member 510 is ≥25mm to ensure reliable positioning of the transmission connection part 400 and the axial rotational stability of the transmission connection part 400. d1 is preferably 25mm, 50mm or 100mm.

[0051] It is understandable that the higher the height H of the limiting engagement between the receiving cavity 452 and the first limiting member 510, the more stable the axial rotation of the transmission connection part 400. In one embodiment, the height H of the limiting engagement between the receiving cavity 452 and the first limiting member 510 is ≥10mm, ensuring reliable positioning of the transmission connection part 400 and ensuring the stability of its axial rotation. H is preferably 10mm, 30mm, 50mm, or 100mm.

[0052] like Figure 2 As shown, in an optional embodiment, the power output assembly 300 includes a power shaft 310, and the transmission connection part 400 includes a first rotating cylinder 410 and a second rotating cylinder 420 connected sequentially from bottom to top. A connection part 430 is also provided at the connection between the first rotating cylinder 410 and the second rotating cylinder 420. The first rotating cylinder 410 is sleeved on the outside of the gearbox 331, and the second rotating cylinder 420 is connected to the screw press 200. One end of the power shaft 310 is connected to the output end of the gear assembly 332, and the other end of the power shaft 310 is connected to the connection part 430.

[0053] Specifically, the axial limiting mechanism 500 includes a gearbox 331, and the second rotating cylinder 420 is disposed within the receiving cavity 210. The transmission connection part 400 is driven to rotate by the power shaft 310. A gearbox 331 is provided between the transmission connection part 400 and the gear assembly 332. The gearbox 331 is a fixed component, while the transmission connection part 400 is a rotatable moving component. The gearbox 331, which constitutes the housing of the reduction assembly 330, can provide axial positioning for the transmission connection part 400, preventing eccentric movement of the transmission connection part 400 during rotation, ensuring reliable positioning of the transmission connection part 400, and ensuring the axial rotational stability of the transmission connection part 400. This results in higher precision and longer service life for the transmission connection part 400, and more reliable positioning of the moving component transmission connection part 400 by the fixed component gearbox 331, leading to more stable operation.

[0054] Furthermore, the outer contour of the transmission connection 400 is adapted to the inner contour of the receiving cavity 210 to improve the connection stability between the transmission connection 400 and the screw press 200. Specifically, when the transmission connection 400 includes a first rotating cylinder 410 and a second rotating cylinder 420, the outer contour of the second rotating cylinder 420 is adapted to the inner contour of the receiving cavity 210; when the transmission connection 400 includes a rotating cylinder 450 and a connecting post 460, the outer contour of the rotating cylinder 450 is adapted to the inner contour of the receiving cavity 210.

[0055] like Figure 2 As shown, the bottom end of the screw press 200 is also provided with a first limiting part 220, which can cooperate with the cup body 100 to limit the axial movement of the screw press 200. Specifically, the first limiting part 220 includes a first limiting platform extending outward from the outer side of the bottom end of the screw press 200, which can abut against the bottom end of the cup body 100 to limit the axial movement of the screw press 200.

[0056] The bottom end of the transmission connection part 400 is also provided with a second limiting part 440, which can cooperate with the motor 320 to limit the axial movement of the transmission connection part 400. Specifically, in this embodiment, the top end of the motor 320 is provided with a mounting base 340, and a first groove 341 is provided in the mounting base 340. The reduction assembly 330 is partially housed in the first groove 341, and the second limiting part 440 is limited in the first groove 341 to limit the axial movement of the transmission connection part 400.

[0057] Specifically, the second limiting part 440 includes a second limiting platform extending outward from the bottom outer side of the transmission connection part 400. The second limiting platform is arranged circumferentially along the first rotating cylinder 410 and is located at the end of the first rotating cylinder 410 away from the second rotating cylinder 420. The mounting base 340 is disposed at the top of the rotating drive member 321. One end of the drive gear 322 is connected to the rotating drive member 321, and the other end of the drive gear 322 extends into the first groove 341 through the bottom of the mounting base 340.

[0058] Furthermore, a second groove 441 is provided at the bottom end of the transmission connection portion 400, and a third limiting portion 442 is provided at the bottom end of the gearbox 331. The third limiting portion 442 is limited within the second groove 441 to restrict the axial movement of the gearbox 331. Specifically, the third limiting portion 442 includes a third limiting platform extending outward from the outer side of the bottom end of the gearbox 331. The third limiting platform is limited within the second groove 441 to restrict the axial movement of the gearbox 331.

[0059] An axial limiting structure 600 is provided between the transmission connection part 400 and the screw press 200. The axial limiting structure 600 is used to limit the axial movement of the screw press 200, ensuring that the relative position of the transmission connection part 400 and the screw press 200 is reliable, thereby ensuring that the rotational operation of the transmission connection part 400 and the screw press 200 in the axial direction is more stable.

[0060] The axial limiting structure 600 includes a retaining rib 610 and a retaining groove 620. One of the transmission connection part 400 and the screw press 200 is provided with the retaining rib 610, and the other of the transmission connection part 400 and the screw press 200 is provided with the retaining groove 620. The retaining rib 610 is engaged within the retaining groove 620 to restrict the axial movement of the screw press 200. Specifically, the retaining groove 620 may be, but is not limited to, a T-slot. The retaining groove 620 is provided on the outer wall of the transmission connection part 400, and the retaining rib 610 is provided on the inner wall of the screw press 200. There are multiple retaining grooves 620 and retaining ribs 610. Multiple retaining grooves 620 are spaced apart on the outer wall of the transmission connection part 400, and multiple retaining ribs 610 are spaced apart on the inner wall of the screw press 200. Each retaining groove 620 corresponds one-to-one with a multiple retaining rib 610.

[0061] Specifically, when the transmission connection part 400 includes a first rotating cylinder 410 and a second rotating cylinder 420, a slot 620 is provided on the outer side wall of the second rotating cylinder 420; when the transmission connection part 400 includes a rotating cylinder 450 and a connecting post 460, a slot 620 is provided on the outer side wall of the rotating cylinder 450.

[0062] like Figure 3As shown, in one embodiment, the cup body 100 includes an inner cup body 110 and an outer cup body 120. The inner cup body 110 includes a feeding cup 130 and a juicing cup 140 connected sequentially from top to bottom. A feeding chamber 132 is formed inside the feeding cup 130, and a juicing chamber 142 is formed inside the juicing cup 140. The outer cup body 120 is detachably fitted onto the outside of the juicing cup 140. Specifically, the food falls from the feeding chamber 132 under gravity and comes into contact with the screw press 200, where it is pressed by the screw press 200 and the cup body 100 to achieve juicing. A first limiting member 510 extends from the inner side of the bottom end of the outer cup body 120 towards the top end of the outer cup body 120, and the bottom end of the screw press 200 extends outside the juicing chamber 142.

[0063] The outer cup body 120 has a juice outlet 121 and a residue outlet 122 on its side wall. The residue outlet 122 and the juice outlet 121 are located on opposite sides of the outer cup body 120. A liquid outlet chamber 150 is also provided between the outer cup body 120 and the juicing cup 140. The liquid outlet chamber 150 is arranged around the circumference of the juicing cup 140 and connects the juicing chamber 142 and the juice outlet 121. The juice in the juicing chamber 142 can be discharged to the outside through the liquid outlet chamber 150 and the juice outlet 121 in sequence. A residue outlet channel 160 is also provided on the inner side of the outer cup body 120. The residue outlet channel 160 connects the juicing chamber 142 and the residue outlet 122. The residue in the juicing chamber 142 can be discharged to the outside through the residue outlet channel 160 and the residue outlet 122 in sequence.

[0064] The inner cup 110 also includes a filter structure 170, which is disposed on the side wall of the juicing cup 140. The filter structure 170 is used to filter the juice and pulp produced after the food is pressed in the juicing chamber 142, so as to separate the juice and pulp. By disposing of the filter structure 170 on the side wall of the juicing cup 140, no additional filter device is required, which facilitates installation, reduces the space occupied by the filter device, and thus reduces the size of the juicer 10 and lowers the material cost. In an optional embodiment, the filter structure 170 includes a plurality of filter holes 172 spaced apart on the side wall of the juicing cup 140. Specifically, the filter holes 172 extend along the height direction of the juicing cup 140, and the plurality of filter holes 172 are arranged circumferentially around the juicing cup 140.

[0065] The inner wall of the inner cup 110 is also provided with a feeding rib 180. The feeding rib 180 is at least partially located in the feeding chamber 132 and extends from the feeding chamber 132 to the end of the juicing chamber 142 away from the feeding chamber 132. The feeding rib 180 is used to guide the food into the juicing chamber 142. Specifically, the feeding rib 180 is arranged along the height direction of the cup 100. The feeding rib 180 can guide the food entering the feeding chamber 132 to facilitate the food entering the juicing chamber 142. At the same time, the feeding rib 180 can provide resistance to the rotation of the food. That is, when the screw press 200 drives the food to rotate, the feeding rib 180 can block the food. The food is crushed by the cooperation between the screw press 200 and the feeding rib 180, so as to further improve the juicing efficiency of the food. Further optimized, the lateral width of the feeding ribs 180 increases first and then decreases from top to bottom. The initial increase in lateral width facilitates the introduction of ingredients into the juicing chamber 142, while the subsequent decrease in lateral width allows the juicing chamber 142 to accommodate more ingredients, thereby improving juicing efficiency. Specifically, the feeding ribs 180 are located within the feeding chamber 132 and the juicing chamber 142, and there are multiple feeding ribs 180 arranged at relative intervals.

[0066] The outer cup body 120 is provided with a first positioning part 181, and the inner cup body 110 is provided with a second positioning part 182.

The pressing screw section 240 includes multiple pressing screw strips 242 disposed on the outer side wall of the screw press body 230. A guide channel 250 is formed between two adjacent pressing screw strips 242. The guide channel 250 extends spirally along the axial direction of the screw press body 230 so that the juice and residue formed after pressing the food can be smoothly discharged from the screw press 200 along the guide channel 250.

[0068] The screw press 200 also includes multiple cutting ribs 260, which are radially and obliquely arranged on the top of the screw press body 230. The cutting ribs 260 are used to pre-cut the food, so that the pressing screw 240 can further cut and grind the food, preventing the screw press 200 from stopping abruptly due to the large volume of the food, thereby improving the juice yield and juicing efficiency of the juicer 10.

[0069] The transmission connection 400 is made of a different material at its contact points with other nearby components to reduce friction between the transmission connection 400 and these components, thereby reducing wear and extending their service life.

[0071] One of the cup body 100 and the housing 700 is provided with a positioning protrusion 710, and the other of the cup body 100 and the housing 700 is provided with a positioning groove 720. The positioning protrusion 710 and the positioning groove 720 cooperate to position the relative position between the cup body 100 and the housing 700.

[0072] Specifically, the bottom of the cup body 100 is provided with a positioning groove 720, and the top of the housing 700 is provided with a positioning protrusion 710. There are multiple positioning grooves 720 and positioning protrusions 710, with the multiple positioning grooves 720 spaced apart on the cup body 100 and the multiple positioning protrusions 710 spaced apart on the housing 700. Each positioning groove 720 corresponds one-to-one with a single positioning protrusion 710. More specifically, the bottom of the outer cup body 120 is provided with a positioning groove 720.

[0073] like Figure 2 As shown, a first sealing element 800 is provided between the transmission connection part 400 and the screw press 200 to improve the sealing performance between the transmission connection part 400 and the screw press 200. Specifically, when the transmission connection part 400 includes a first rotating cylinder 410 and a second rotating cylinder 420, the first sealing element 800 is provided between the second rotating cylinder 420 and the screw press 200; when the transmission connection part 400 includes a rotating cylinder 450 and a connecting column 460, the first sealing element 800 is provided between the rotating cylinder 450 and the screw press 200.

[0074] A second sealing element 810 is provided between the transmission connection part 400 and the outer cup body 120 to improve the sealing performance between the transmission connection part 400 and the outer cup body 120. Specifically, when the transmission connection part 400 includes a first rotating cylinder 410 and a second rotating cylinder 420, the second sealing element 810 is provided between the second rotating cylinder 420 and the outer cup body 120.

[0075] A third sealing element 820 is provided between the transmission connection part 400 and the housing 700 to improve the sealing performance between the transmission connection part 400 and the housing 700. Specifically, when the transmission connection part 400 includes a first rotating cylinder 410 and a second rotating cylinder 420, a third sealing element 820 is provided between the first rotating cylinder 410 and the housing 700.
