[0029] Please refer to Figure 1 and Figure 2 The utility model proposes a juicer 10, including a frame 100, a rolling disc 200, a pressure member 300 and a driving assembly 400. The rolling disc 200 is installed on the frame 100; the pressure member 300 is installed on the frame 100 and is arranged below the rolling disc 200, and the pressure member 300 is used to place the squeezed material; the driving assembly 400 is installed on the frame 100, and the driving assembly 400 includes a driving member 410, a driving gear 430, a plurality of transmission gears 440 and a plurality of screw rods 420. The driving member 410 drives and connects the driving gear 430, and the plurality of transmission gears 440 are meshed with the driving gear 430 and are connected to the plurality of screw rods 420 one by one. The screw rods 420 are connected to one of the rolling disc 200 and the pressure member 300, so that the rolling disc 200 and the pressure member 300 can be close to or away from each other.

[0030] Specifically, the juicer 10 proposed by the utility model is used to squeeze juice from squeezed objects, and the squeezed objects can be large watermelons, cantaloupes, etc., medium-sized oranges, passion fruits, etc., small grapes, kumquats, etc., or vegetables with more juice, such as cucumbers and tomatoes, etc., which are not specifically limited in this application. In addition, during a squeezing process, the juicer 10 can be used for only one squeezed object, such as a large watermelon or a medium-sized orange, or for multiple squeezed objects at the same time, such as rolling multiple grapes at the same time.

[0031] The juicer 10 includes a frame 100, a rolling plate 200, a pressure member 300 and a drive assembly 400. The frame 100 is used to install and support the rolling plate 200, the pressure member 300 and the drive assembly 400, and plays the role of supporting and fixing each component to ensure the stability and reliability of the entire juicer 10. The rolling plate 200 is installed on the frame 100 and is used to squeeze the squeezed material to extract juice. The rolling plate 200 can be fixed on the frame 100, or it can be swung on the frame 100. Two driving members 410 are provided in the figure, one of which is used to drive the screw rod 420 to rotate, and the other is used to drive the rolling plate 200 to swung. The pressure member 300 is installed on the frame 100 and is located below the rolling plate 200, and is used to stably place the squeezed material, that is, the fruits and vegetables to be squeezed.

[0032] The driving assembly 400 is installed on the frame 100. The driving assembly 400 includes a driving member 410, a driving gear 430, a transmission gear 440 and a screw rod 420. The driving member 410 can drive the screw rod 420 to rotate through the driving gear 430 and the transmission gear 440, so as to control one of the rolling disc 200 and the pressure member 300 to approach or move away from each other, so as to adjust the distance between the pressure member 300 and the rolling disc 200, and realize the control of the squeezing process of fruits and vegetables. The screw rod 420 can be connected to the pressure member 300. When the driving member 410 is started, the pressure member 300 can rise and approach the rolling disc 200 to squeeze the fruits and vegetables; or the pressure member 300 can fall and move away from the rolling disc 200 to facilitate the removal of residues and the placement of new squeezed materials. The screw rod 420 can also be connected to the rolling disc 200. When the driving member 410 is started, the rolling disc 200 can be lowered and approach the pressure member 300 to squeeze the fruits and vegetables; or the rolling disc 200 can be raised and away from the pressure member 300 to facilitate the removal of residues and the placement of new squeezed objects. The juicer 10 cooperates with the driving member 410, the driving gear 430, the transmission gear 440 and the screw rod 420. The screw rod 420 converts the rotational motion into linear motion, so that the driving force of the driving member 410 can be transmitted to the rolling disc 200 and the pressure member 300, so that the rolling disc 200 and the pressure member 300 can be close to or away from each other in the vertical direction, so as to realize the control of the squeezing and extrusion process of fruits and vegetables and improve the working efficiency of the juicer 10.

[0033] The plurality of transmission gears 440 mesh with the same driving gear 430. When the driving member 410 is started, the driving gear 430 starts to rotate. Under the rotation of the driving gear 430, the plurality of transmission gears 440 meshed therewith rotate synchronously. Therefore, the plurality of transmission gears 440 are synchronized with each other, and the plurality of lead screws 420 connected to the transmission gears 440 are synchronized with each other.

[0034] By meshing a driving gear 430 with multiple transmission gears 440, a driving member 410 drives multiple screw rods 420 to rotate simultaneously, thereby realizing synchronous control of multiple screw rods 420, ensuring that the rotation speeds of each screw rod 420 remain consistent, and then the moving positions of different areas of the rolling disc 200 or the pressure-bearing member 300 controlled by different screw rods 420 remain consistent, so as to maintain the overall synchronization and balance of the rolling disc 200 or the pressure-bearing member 300, effectively solving the problem of imbalance of the rolling disc 200 or the pressure-bearing member 300 caused by the asynchronous rotation of the screw rods 420, and improving the stability of the juicer 10.

[0035] In one embodiment, the frame 100 includes a first mounting plate 110 and a second mounting plate 120 respectively disposed at both ends of the screw rod 420, the first mounting plate 110 is disposed above the second mounting plate 120, the pressure-bearing member 300 and the rolling disc 200 are disposed between the first mounting plate 110 and the second mounting plate 120, and the driving member 410, the driving gear 430 and a plurality of transmission gears 440 are disposed on the first mounting plate 110.

[0036] Please refer to Figure 2 The screw rod 420 is rotatably connected to the first mounting plate 110 and the second mounting plate 120 through bearings. The first mounting plate 110 and the second mounting plate 120 are arranged at both ends of the screw rod 420 to form an installation space. The pressure-bearing member 300 and the rolling plate 200 are arranged between the first mounting plate 110 and the second mounting plate 120, so that the distance and position between them can be effectively controlled and adjusted to meet the needs of fruit and vegetable juice extraction of different sizes. When the screw rod 420 is connected to the pressure-bearing member 300, the rolling plate 200 is installed on the first mounting plate 110, and the pressure-bearing member 300 can move up and down between the first mounting plate 110 and the second mounting plate 120; when the screw rod 420 is connected to the rolling plate 200, the pressure-bearing member 300 is installed on the second mounting plate 120, and the rolling plate 200 can move up and down between the first mounting plate 110 and the second mounting plate 120. The driving member 410, the driving gear 430 and the plurality of transmission gears 440 are arranged on the first mounting plate 110. The first mounting plate 110 serves as an upper support and provides a suitable position for the installation of the driving member 410, the driving gear 430 and the transmission gear 440, so as to facilitate the driving and control of the rolling plate 200 and the pressure member 300. At the same time, the structural design of the first mounting plate 110 and the second mounting plate 120 is also conducive to maintenance and repair, thereby improving the reliability and service life of the juice extractor 10.

[0037] In one embodiment, the rolling disc 200, the driving member 410, the driving gear 430 and the plurality of transmission gears 440 are mounted on the first mounting plate 110, and the screw rod 420 is movably connected to the pressure member 300 to drive the pressure member 300 to move up and down.

[0038] Please refer to Figure 1 and Figure 2 The rolling disc 200, the driving member 410, the driving gear 430 and the plurality of transmission gears 440 are all mounted on the first mounting plate 110, the screw rod 420 is connected to the pressure member 300, the pressure member 300 can move up and down between the first mounting plate 110 and the second mounting plate 120, and the pressure member 300 can be precisely moved and adjusted in the vertical direction, so that the juice extractor 10 can properly squeeze and extract the squeezed material as needed, ensuring uniform and efficient juicing. Moreover, the pressure member 300 is smaller in size and weight than the rolling disc 200, and the driving member 410 drives the pressure member 300 to move up and down to save more energy, which plays a role in energy saving and environmental protection.

[0039] The rolling disc 200, the driving member 410, the driving gear 430 and the transmission gear 440 can all be arranged on a side of the first mounting plate 110 close to the second mounting plate 120; or the rolling disc 200 can be arranged on a side of the first mounting plate 110 close to the second mounting plate 120, and the driving member 410, the driving gear 430 and the transmission gear 440 can all be arranged on the other side of the first mounting plate 110 away from the second mounting plate 120.

[0040] In addition, the rolling disc 200, the driving member 410, the driving gear 430 and the multiple transmission gears 440 are all installed on the first mounting plate 110 to form a compact module, which can be pre-assembled on the same sub-assembly line, and the remaining components can be assembled on another sub-assembly line. The two sub-assembly lines are assembled synchronously and then assembled together, which can improve production efficiency.

[0041] In one embodiment, the rolling disc 200 is installed on a side of the first mounting plate 110 close to the second mounting plate 120 , and the driving member 410 , the driving gear 430 and the plurality of transmission gears 440 are disposed on another side of the first mounting plate 110 away from the second mounting plate 120 .

[0042] Please refer to Figure 1 and Figure 2The driving member 410 is arranged on the side of the first mounting plate 110 away from the second mounting plate 120, which can provide sufficient power and rotational force. The driving gear 430 and the transmission gear 440 are arranged on the side where the driving member 410 is located, so as to facilitate the transmission of the power of the driving member 410 to the screw rod 420, so as to drive the screw rod 420 to rotate and thus drive the pressure member 300 to move up and down. The rolling plate 200 is arranged on the other side of the first mounting plate 110 to ensure the balance and stability during the juicing process, reduce vibration and unstable factors, and improve the working efficiency and stability of the juicer 10. By arranging the driving gear 430, the transmission gear 440, the driving member 410 and the rolling plate 200 on the two opposite sides of the first mounting plate 110, the structural optimization and functional division of the juicer 10 are achieved, so that the juicer 10 can operate more efficiently during the juicing process and improve the juicing efficiency.

[0043] In one embodiment, the transmission gear 440 includes a first gear 441 and a second gear 442 that are meshed with each other. The first gear 441 is meshed with the driving gear 430 , and the second gear 442 is connected to the lead screw 420 .

[0044] Please refer to Figure 2 The transmission gear 440 includes a first gear 441 and a second gear 442 that are meshed with each other. The first gear 441 is meshed with the driving gear 430 to transmit power to the screw rod 420, drive and control the screw rod 420, and thus move the pressure member 300 up and down. The installation positions of the first gear 441 and the second gear 442 can be arranged according to the size of the juicer 10, so that the first gear 441 and the second gear 442 of the same specification can be adapted to juicers 10 of different sizes, thereby reducing the R&D cost and improving the production efficiency. The specifications of the first gear 441 and the second gear 442 can be consistent or different. When the diameter of the second gear 442 is larger than the diameter of the first gear 441, the second diameter has a deceleration effect on the screw rod 420; when the diameter of the second gear 442 is smaller than the diameter of the first gear 441, the second diameter has an acceleration effect on the screw rod 420. In addition, one or more second gears 442 can be provided. When one second gear 442 is provided, one first gear 441 transmits the power of the driving member 410 to one second gear 442 and drives one screw rod 420 to rotate; when multiple second gears 442 are provided, multiple second gears 442 mesh with the first gear 441, or one second gear 442 meshes with another second gear 442, so that one first gear 441 transmits the power of the driving member 410 to multiple second gears 442 and drives multiple screw rods 420 to rotate. In other embodiments, the first gear 441 and the second gear 442 can also be configured as the same gear, that is, one gear meshes with the driving gear 430 and connects the screw rod 420.

[0045] In one embodiment, two transmission gears 440 and two screw rods 420 are respectively provided, and the two transmission gears 440 are arranged on opposite sides of the driving gear 430. The two screw rods 420 correspond to the two transmission gears 440, which are arranged on opposite sides of the pressure-bearing member 300, and are connected to the two second gears 442 one by one.

[0046] Please refer to Figure 1 and Figure 2 The driving assembly 400 includes a driving member 410, a driving gear 430 connected to the driving member 410, two first gears 441, two second gears 442 and two screw rods 420. The two first gears 441 are arranged on opposite sides of the driving gear 430 and mesh with the driving gear 430. The two second gears 442 mesh with the two first gears 441 one by one and are connected to the two screw rods 420 one by one. The arrangement of the two transmission gears 440 enables the driving force of the driving member 410 to be more evenly transmitted to the pressure member 300, reduces the energy loss and vibration during the transmission process, and improves the stability and working efficiency of the juicer 10. At the same time, the corresponding connection between the two screw rods 420 and the second gears 442 makes the up and down movement of the pressure member 300 more stable and accurate, ensuring the reliability and accuracy of the juicer 10 during operation.

[0047] By meshing a driving gear 430 with two transmission gears 440, a driving member 410 drives two screw rods 420 to rotate simultaneously, thereby realizing synchronous control of the two screw rods 420, ensuring that the rotation speeds of the two screw rods 420 remain consistent, and then the moving positions of the two sides of the pressure-bearing member 300 controlled by the two screw rods 420 remain consistent, so as to maintain the synchronization and balance of the two sides of the pressure-bearing member 300, effectively solving the problem of imbalance of the pressure-bearing member 300 caused by the asynchronous rotation of the screw rods 420, and improving the stability of the juicer 10.

[0048] In one embodiment, the pressure-bearing member 300 includes a support seat 310 and a filter screen 320 , the screw rod 420 passes through the support seat 310 , the filter screen 320 is disposed between the support seat 310 and the rolling disc 200 , and is connected to the support seat 310 , and a juice storage space 330 is formed between the filter screen 320 and the support seat 310 .

[0049] Please refer to Figure 1 and Figure 2In the process of squeezing fruits and vegetables, juice and residue can be effectively separated through the filter 320, and the juice flows from the filter 320 into the juice storage space 330 below it and is collected and stored, avoiding overflow and waste of juice; at the same time, the setting of the filter 320 effectively filters the solid particles in the fruits and vegetables, ensuring that the squeezed juice is pure in quality and tastes better. As an important part of the pressure-bearing member 300, the support seat 310 can not only stably support the filter 320, but also move up and down through the drive of the screw rod 420, adjust the distance between the pressure-bearing member 300 and the rolling disc 200, and thus control the pressure and speed of the juicing process. The juicer 10 can also be provided with a juice storage box, which can be pulled out of the juice storage space 330. The user can easily pull out the juice storage box to conveniently pour out the stored juice or perform cleaning and maintenance, so that the user can more conveniently handle the juice when using the juicer 10, improving the user experience and the convenience of operation. When the juice box is arranged in the juice storage space 330, the juice box is connected with the filter holes of the filter screen 320, so that the juice can flow into the juice box smoothly. At the same time, impurities such as pomace can be filtered out through the filtering effect of the filter holes, ensuring that the stored juice is clear and transparent, improving the quality and taste of the juice, and providing users with healthier and more delicious juice drinks.

[0050] In one embodiment, the frame 100 further includes a plurality of guide shafts 130 extending in the vertical direction, the support seat 310 is provided with through holes for the guide shafts 130 to pass through, and two ends of the guide shafts 130 are respectively connected to the first mounting plate 110 and the second mounting plate 120 .

[0051] Please refer to Figure 2 The frame 100 further includes a plurality of guide shafts 130, which extend in the vertical direction and pass through the through holes of the support base 310 to enhance the stability and load-bearing capacity of the frame 100. The arrangement of these guide shafts 130 makes the structure of the frame 100 more solid, and can effectively support and fix various components in the machine, ensuring that the juice extractor 10 will not shake or deform during operation.

[0052] The two ends of each guide shaft 130 are respectively connected to the first mounting plate 110 and the second mounting plate 120. Through this connection method, the guide shaft 130 can tightly fix the first mounting plate 110 and the second mounting plate 120 together to form an overall stable frame 100 structure. The vertical extension design of the guide shaft 130 enables the frame 100 to evenly distribute the load when subjected to external pressure and vibration, reduces the deformation and damage of the machine, and improves the service life and stability of the juicer 10. Multiple guide shafts 130 are passed through the support seat 310, which can not only increase the support area of ​​the frame 100, but also effectively disperse and absorb external impact forces. At the same time, the guide shaft 130 also provides a guiding function for the movement of the pressure-bearing member 300.

[0053] In one embodiment, the juice extractor 10 further includes a linear bearing 500 . The linear bearing 500 is disposed in the through hole and sleeved on the outer circumference of the guide shaft 130 .

[0054] Please refer to Figure 2 , the linear bearing 500 is sleeved on the outer circumference of the guide shaft 130, which can ensure the smooth movement of the guide shaft 130. The linear bearing 500 usually adopts a high-precision manufacturing process to ensure the accuracy of its size and shape, so that during the juicing process, the linear bearing 500 can provide a smooth, smooth and accurate guide, thereby reducing the error caused by unstable movement during the juicing process; the linear bearing 500 has a long service life and reliability. During long-term use, the performance of the bearing will not be significantly reduced due to wear or fatigue, thereby ensuring the consistency of the movement of the pressure-bearing part 300; the friction force of the linear bearing 500 remains constant during operation, so that the movement of the guide shaft 130 through the linear bearing 500 is more stable and predictable, so that the movement of the pressure-bearing part 300 is also more stable and predictable, thereby improving the consistency of the up and down movement of the pressure-bearing part 300, and ensuring the stability and reliability of the juicer 10 during long-term operation.

[0055] In one embodiment, the juicer 10 further includes a position sensor 600, which is movably disposed on the guide shaft 130 and is located above the pressure-bearing member 300. When the position sensor 600 senses the pressure-bearing member 300, the pressure-bearing member 300 stops rising.

[0056] Please refer to Figure 2 Through the application of the position sensor 600, the juicer 10 can monitor and control the position of the pressure-bearing member 300 in real time during operation, ensuring the safety and stability of the juicer 10 during operation. When the pressure-bearing member 300 reaches the preset position, the position sensor 600 can sense the pressure-bearing member 300 and send a signal in time, so that the juicer 10 can accurately stop the upward movement of the pressure-bearing member 300, avoiding accidents caused by misoperation or other reasons, and ensuring the safety of operators and equipment.
