Juicer

Abstract

This application discloses a juicer, including a cup body, a screw press, a power mechanism, a transmission connection, and a positioning component for the transmission connection. The cup body includes an inner cup body and an outer cup body, the inner cup body having a juicing chamber, and the outer cup body located outside the inner cup body. The screw press is rotatably disposed within the juicing chamber. The power mechanism is disposed below the cup body. The transmission connection is rotatably disposed on the outer cup body and drivesly connects the screw press and the power mechanism. The positioning component for the transmission connection is disposed on the outer cup body and is used to position the transmission connection in its axial direction. By placing the positioning component for the transmission connection on the outer cup body, the distance between the positioning component and the force-bearing point of the transmission connection can be effectively shortened. Thus, when the transmission connection is subjected to the same lateral force, the lever arm is shorter, and the force between the transmission connection and the positioning component is smaller, making the screw press operate more stably.

Description

Technical Field

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

[0002] Existing juicers typically connect the screw press and the power mechanism located below the cup body via an output shaft. Since the output shaft is relatively long, in order to improve the operational stability of the output shaft and prevent eccentric movement during rotation, an output shaft positioning component is usually installed on the power mechanism located below the cup body. This output shaft positioning component is used to position the output shaft axially upward.

[0003] However, since the output shaft positioning component is usually located on the power mechanism below the cup body, and the screw press is rotated in the juicing chamber of the cup body, and the force point of the output shaft is close to the juicing chamber, the distance between the output shaft positioning component and the force point of the output shaft is relatively large, which causes the screw press to be unstable during operation, resulting in vibration and noise problems. Summary of the Invention

[0004] Therefore, it is necessary to provide a juicer with stable operation of the screw press.

[0005] A juicer, comprising:

[0006] The cup body includes an inner cup body and an outer cup body, wherein the inner cup body has a juicing chamber, and the outer cup body is located on the outside of the inner cup body;

[0007] A screw press is rotatably mounted inside the juicing chamber;

[0008] The power mechanism is located below the cup body;

[0009] A transmission connection is rotatably mounted on the outer cup body, and the transmission connection is drivingly connected to the screw press and the power mechanism; and

[0010] A transmission connection positioning component is disposed on the outer cup body, and the transmission connection positioning component is used to position the transmission connection part in its own axial direction.

[0011] The juicer provided in this application has a power mechanism that drives a screw press to rotate via a transmission connection, enabling the screw press to work with the inner cup to squeeze and juice the ingredients placed in the juicing chamber. In this design, the transmission connection positioning component is located on the outer cup. Firstly, this component positions the transmission connection on its axial direction, preventing eccentric movement during rotation and resulting in higher precision, more stable operation, and a longer lifespan. Secondly, during operation, the screw press within the juicing chamber is subjected to both axial and lateral forces. Since the transmission connection is attached to the screw press, these forces are transmitted to the transmission connection, and the force point of the transmission connection is close to the juicing chamber. Compared to traditional methods, this design provides a more efficient and stable connection. Regarding the arrangement of the power mechanism located below the cup body, by placing the transmission connection positioning component on the outer cup body, the distance between the positioning component and the force-bearing point of the transmission connection can be effectively shortened. This results in a shorter lever arm when the transmission connection is subjected to the same lateral force, leading to less stress between the transmission connection and the positioning component. This makes the screw press operate more stably and avoids vibration and noise problems caused by an excessively large distance between the positioning component and the force-bearing point of the transmission connection. Furthermore, a smaller distance between the positioning component and the force-bearing point of the transmission connection allows it to withstand greater forces, ensuring its structural integrity, preventing structural deformation, and extending its service life.

[0019] like Figure 1 and Figure 2 As shown, this application provides a juicer 10, which includes a cup body 100, a screw press 200, a power mechanism 300, a transmission connection part 400, and a transmission connection part positioning member 500. The cup body 100 includes an inner cup body 110 and an outer cup body 120. The inner cup body 110 has a juicing chamber 142, and the outer cup body 120 is located outside the inner cup body 110. The screw press 200 is rotatably disposed in the juicing chamber 142. The power mechanism 300 is disposed below the cup body 100. The transmission connection part 400 is rotatably disposed on the outer cup body 120, and the transmission connection part 400 drivesly connects the screw press 200 and the power mechanism 300. The transmission connection part positioning member 500 is disposed on the outer cup body 120 and is used to position the transmission connection part 400 in its own axial direction.

[0020] The juicer 10 provided in this application has a power mechanism 300 that can drive the screw press 200 to rotate via the transmission connection 400, so that the screw press 200, in conjunction with the inner cup 110, can perform the squeezing and juicing operation on the ingredients put into the juicing chamber 142. In this solution, the transmission connection positioning member 500 is provided on the outer cup 120. On the one hand, the transmission connection positioning member 500 can position the transmission connection 400 in its own axial direction, preventing the transmission connection 400 from rotating during operation. During the process, eccentric motion occurs, resulting in higher precision, more stable operation, and longer lifespan for the transmission connection 400. On the other hand, during operation, the screw press 200 located in the juicing chamber 142 of the juicer 10 is simultaneously subjected to axial and lateral forces. Since the transmission connection 400 is connected to the screw press 200, the axial and lateral forces on the screw press 200 are transmitted to the transmission connection 400. Furthermore, the force-bearing point of the transmission connection 400 is close to the juicing chamber 142, which is more efficient than traditional methods. Regarding the arrangement of the transmission connection positioning component on the power mechanism located below the cup body, by placing the transmission connection positioning component 500 on the outer cup body 120, the distance between the force-bearing points of the transmission connection 400 and the transmission connection 400 can be effectively shortened. Thus, when the transmission connection 400 is subjected to the same lateral force, the lever arm is shorter, resulting in less stress between the transmission connection 400 and the transmission connection positioning component 500. This makes the screw press 200 operate more stably, avoiding vibration and noise problems caused by an excessively large distance between the force-bearing points of the transmission connection 400 and the transmission connection positioning component 500 during operation. Furthermore, a smaller distance between the force-bearing points of the transmission connection 500 and the transmission connection 400 allows the transmission connection positioning component 500 to withstand greater forces, thereby ensuring the structural integrity of the transmission connection positioning component 500, preventing structural deformation, and extending the service life of the transmission connection positioning component 500.

[0021] It should be noted that the transmission connection positioning member 500 being disposed on the outer cup body 120 includes at least: the transmission connection positioning member 500 being mounted on the outer cup body 120, or the transmission connection positioning member 500 being integrally formed with the outer cup body 120.

[0022] like Figure 2 As shown, the transmission connection 400 has a connecting shaft 410, which drives the screw press 200 and the power mechanism 300. The transmission connection positioning member 500 has a positioning hole 510, in which the connecting shaft 410 is inserted to position the transmission connection 400 in its own axial direction. Specifically, the positioning hole 510 extends along the axial direction of the transmission connection positioning member 500 and passes through the top and bottom ends of the transmission connection positioning member 500.

[0023] In an optional embodiment, the positioning member 500 of the transmission connection part is a first bearing 501, and the center hole of the first bearing 501 forms a positioning hole 510. Preferably, a seal is provided at one end of the first bearing 501, or both ends of the first bearing 501 are provided with seals, so as to improve the sealing performance of the first bearing 501, prevent the first bearing 501 from being corroded and damaged by water ingress, and thus extend the service life of the first bearing 501.

[0024] like Figure 2 As shown, a first limiting member 520 is also provided on the connecting shaft 410. Specifically, the first limiting member 520 is provided at the bottom end of the connecting shaft 410. The first limiting member 520 is used to limit the axial movement of the connecting shaft 410, so as to further improve 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.

[0025] A partition 530 is also provided between the transmission connection positioning member 500 and the first limiting member 520. Specifically, when the transmission connection 400 moves upward along its own axis during rotation, the partition 530 can separate the transmission connection positioning member 500 and the first limiting member 520, preventing them from directly contacting each other. This solves the problems of reduced durability, noise, vibration, and heat caused by friction between the transmission connection positioning member 500 and the first limiting member 520.

[0026] Preferably, the partition 530 is a second bearing 531, which is sleeved on the outside of the connecting shaft 410. The second bearing 531 is a plane bearing. When the transmission connection part 400 moves upward along its own axis during rotation, the plane bearing located between the transmission connection part positioning part 500 and the first limiting part 520 can change the sliding friction between the transmission connection part positioning part 500 and the first limiting part 520 into rolling friction, so that the wear of the transmission connection part positioning part 500 and the first limiting part 520 is smaller and the service life is longer.

[0027] like Figure 2 As shown, a through hole 101 is provided at the center of the outer cup body 120, and the connecting shaft 410 extends into the through hole 101. The transmission connection positioning member 500 is disposed between the inner wall of the through hole 101 and the outer wall of the connecting shaft 410.

[0028] The outer cup body 120 has a second limiting member 102, which extends from the inner side of the bottom end of the outer cup body 120 towards the top end. The transmission connection part 400 is rotatably sleeved on the outer side of the second limiting member 102 to restrict the axial movement of the transmission connection part 400. The second limiting member 102 is a fixed component, while the transmission connection part 400 is a rotatable moving component. The second limiting member 102 can abut against the inner wall of the transmission connection part 400, 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 second limiting member 102 is more reliable, and the operation is more stable.

[0029] Specifically, the second limiting member 102 is provided with a through hole 101, which extends from the top end of the second limiting member 102 to the bottom end of the second limiting member 102. The inner wall of the second limiting member 102 forms the inner wall of the through hole 101. The transmission connection positioning member 500 is disposed between the inner wall of the second limiting member 102 and the outer wall of the connecting shaft 410. The top end face of the transmission connection positioning member 500 is flush with the top end face of the second limiting member 102. The first limiting member 520 and the partition member 530 are both disposed in the through hole 101.

[0030] like Figure 2 As shown, the transmission connection part 400 also includes a rotating cylinder 420 connected to the connecting shaft 410. The rotating cylinder 420 is rotatably mounted on the outer cup body 120 and connected to the screw press 200. Further, the rotating cylinder 420 has a receiving cavity 422, and the connecting shaft 410 is connected to the top end of the receiving cavity 422 and extends towards the bottom end of the receiving cavity 422. Specifically, the rotating cylinder 420 and the connecting shaft 410 are coaxially arranged. The rotating cylinder 420 is a hollow structure with a closed top and an open bottom. The rotating cylinder 420 is rotatably sleeved on the outside of the second limiting member 102, and the bottom end of the connecting shaft 410 extends to the outside of the receiving cavity 422. The rotating cylinder 420 and the connecting shaft 410 are integrally formed.

[0031] The screw press 200 has an internal receiving cavity 210, and the transmission connection part 400 is disposed in the receiving cavity 210. The transmission connection part 400 extends into the receiving cavity 210, which can effectively increase the axial length of the connection between the transmission connection part 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.

[0032] In one embodiment, the depth of the transmission connection 400 extending into the receiving cavity 210 is ≥20mm, so as to ensure 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.

[0033] like Figure 2 As shown, the power mechanism 300 includes a motor 310 and a reduction gear assembly 320. The reduction gear assembly 320 includes a gearbox 321 and a gear assembly 322. The gear assembly 322 is movably disposed within the gearbox 321. The motor 310 is connected to the gearbox 321 and is drivenly connected to the input end of the gear assembly 322. The transmission connection part 400 is drivenly connected to the output end of the gear assembly 322. By setting the reduction gear assembly 320, the power mechanism 300 can achieve a speed reduction and torque increase effect, thereby increasing the pressing force of the screw press 200 and improving the juicing effect of the juicer 10.

[0034] The gearbox 321 has an internal gear ring 323 on its inner wall. The gear assembly 322 includes a planet carrier 324, a sun gear, and multiple planetary gears 325. The sun gear is connected to one side of the planet carrier 324. The planetary gears 325 are rotatably connected to the planet carrier 324 and mesh with the internal gear ring 323. The multiple planetary gears 325 are evenly arranged along the circumference of the planet carrier 324, with the planetary gears 325 located on the side of the planet carrier 324 away from the sun gear. The transmission connection part 400 is connected to the sun gear. The motor 310 includes a drive gear 312 and a rotary drive member 314. The drive gear 312 is connected to the output end of the rotary drive member 314 and meshes with the planetary gears 325. Specifically, when the rotary drive member 314 outputs power through the drive gear 312, the drive gear 312 can mesh with the planetary gears 325 of the reduction assembly 320 and drive the planet carrier 324 to rotate, thereby driving the sun gear to rotate, thus achieving the reduction effect of the reduction assembly 320.

[0035] Furthermore, the power mechanism 300 has a power shaft 330, specifically, the power shaft 330 is drive-connected to the output end of the gear assembly 322, the rotating cylinder 420 is disposed within the receiving cavity 210, and the power shaft 330 is connected to the connecting shaft 410. One end of the power shaft 330 is sleeved within the connecting shaft 410, and the cross-sectional shape of the end of the power shaft 330 that abuts the connecting shaft 410 is polygonal to restrict the rotation of the connecting shaft 410 relative to the power shaft 330 and improve the connection stability between the power shaft 330 and the connecting shaft 410.

[0036] In one embodiment, the maximum outer diameter of the positioning point between the transmission connection 400 and the outer cup 120 is greater than half the minimum inner diameter of the juicing chamber 142. Since the outer cup 120 is a fixed component, and the transmission connection 400 is a rotatable component, the transmission connection 400 is rotatably mounted on the outer cup 120. The maximum outer diameter of the positioning point between the transmission connection 400 and the outer cup 120 is greater than half the minimum inner diameter of the juicing chamber 142. This structural arrangement has at least the following beneficial effects:

[0037] 1) When the juicer 10 is working, the screw press 200 is subjected to lateral extrusion force, the transmission connection 400 can better maintain verticality (i.e., the axial position of the transmission connection 400) 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.

[0038] 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 positioning point between the transmission connection part 400 and the outer cup body 120, the smaller the power required. This not only makes the transmission connection part 400 more stable, but also reduces the friction between the transmission connection part 400 and the outer cup body 120. Therefore, the transmission connection part 400 operates more stably and has a longer service life.

[0039] 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 transmission connection part 400 and the outer cup body 120 is greater than half the minimum inner diameter of the juicing chamber 142 can effectively ensure the structural strength of the transmission connection part 400 and extend its service life.

[0040] It should be noted that the positioning point of the transmission connection part 400 and the outer cup body 120 described in this application can be understood as the position where the transmission connection part 400 and the outer cup body 120 come into contact with each other during the operation of the juicer 10.

[0041] In one embodiment, the transmission connection 400 is detachably connected to both the screw press 200 and the power mechanism 300, so that the transmission connection 400 can be disassembled for separate cleaning.

[0042] like Figure 2 As shown, 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.

[0043] 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. Specifically, a slot 620 is provided on the outer wall of the rotating cylinder 420.

[0044] like Figure 2 As shown, the bottom end of the screw press 200 extends outside the juicing chamber 142. A limiting portion 220 is also provided at the bottom end of the screw press 200. The limiting portion 220 can cooperate with the inner cup 110 to restrict the axial movement of the screw press 200. Specifically, the limiting portion 220 includes a limiting platform extending outward from the outer side of the bottom end of the screw press 200. The limiting platform can abut against the bottom end of the inner cup 110 to restrict the axial movement of the screw press 200.

[0045] like Figure 1 As shown, the inner cup body 110 includes a feeding cup 130 and a juicing cup 140 connected sequentially from top to bottom. The feeding cup 130 has a feeding chamber 132, and the juicing cup 140 has a juicing chamber 142. 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 inner cup body 110 to achieve juicing.

[0046] 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.

[0047] 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.

[0048] 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.

[0049] 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 first positioning part 181 and the second positioning part 182 cooperate to position the relative position between the outer cup body 120 and the inner cup body 110.

[0050] like Figure 3As shown, the screw press 200 includes a screw press body 230 and a pressing screw section 240. The pressing screw section 240 is disposed on the outer side wall of the screw press body 230 and is used to press the food to extract juice. 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.

[0051] The top of the screw press 200 has a pre-cutting blade 260, which is used to pre-cut the ingredients so that the screw press 200 can further finely cut and grind the ingredients, preventing the screw press 200 from stopping abruptly due to the large volume of the ingredients, thereby improving the juice yield and juicing efficiency of the juicer 10.

[0052] Preferably, the pre-cutting blade 260 is made of metal, and the metal pre-cutting blade has high strength to improve the pre-cutting effect of the pre-cutting blade 260.

[0053] Specifically, the pre-cutting blade 260 includes multiple cutting ribs 262, which are radially and obliquely arranged on the top of the screw press body 230. The cutting ribs 262 are used to pre-cut the food so that the pressing screw part 240240 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.

[0054] The material of the contact area between the transmission connection part 400 and other adjacent components is different to reduce the friction between the transmission connection part 400 and other adjacent components, thereby reducing wear on the transmission connection part 400 and other adjacent components and extending their service life. Figure 2 As shown, specifically, the materials at the contact points between the rotating cylinder 420 and the second limiting member 102 are different, and the materials at the contact points between the connecting shaft 410 and the transmission connection positioning member 500 are different.

[0055] like Figure 1 As shown, the juicer 10 further includes a housing 700, a cup body 100 detachably connected to the housing 700, and at least a portion of the power mechanism 300 housed within the housing 700. Specifically, the outer cup body 120 is detachably connected to the housing 700, the motor 310 is housed within the housing 700, and the reduction gear assembly 320 is partially housed within the housing 700.

[0056] The above are merely preferred embodiments of the present invention and do not limit the scope of the patent. Any equivalent structural transformations made using the contents of the specification and drawings of the present invention under the inventive concept of the present invention, or direct / indirect applications in other related technical fields, are included within the scope of patent protection of the present invention.
