[0032] Please refer to Figures 1 to 4 The utility model proposes a juicer 10, including a frame 100 and a rolling disc 200, a pressure-bearing member 300, and a lifting mechanism 400 installed on the frame 100. The pressure-bearing member 300 is arranged below the rolling disc 200, and the pressure-bearing member 300 is used to place the squeezed material; the lifting mechanism 400 includes a plurality of nut assemblies 430 and a plurality of screw rods 420, one of the rolling disc 200 and the pressure-bearing member 300 is provided with a connecting member 330, and the connecting member 330 is provided with a mounting hole 331 for the screw rod 420 to pass through, the nut assemblies 430 are sleeved on the outer circumference of the screw rod 420 in a one-to-one correspondence and connected to the connecting member 330, and at least one nut assembly 430 is provided with a plurality of adjustment parts 4311 on its circumference.

[0033] 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.

[0034] The juice extractor 10 comprises a frame 100, a rolling plate 200, a pressure member 300 and a lifting mechanism 400. The frame 100 is used to install and support the rolling plate 200, the pressure member 300 and the lifting mechanism 400. 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 can be swung on the frame 100. 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.

[0035] The lifting mechanism 400 includes a plurality of nut assemblies 430 and a plurality of screw rods 420. The screw rods 420 pass through the mounting holes 331 of the connecting member 330. When the screw rods 420 rotate, the connecting member 330 can move along the axis direction of the screw rods 420 under the action of the nut assemblies 430. The connecting member 330 can be arranged on the rolling disc 200, so that the screw rods 420 can drive the rolling disc 200 to move, so that it is close to or away from the pressure member 300; the connecting member 330 can also be arranged on the pressure member 300, so that the screw rods 420 can drive the pressure member 300 to move, so that it is close to or away from the rolling disc 200. The screw rods 420 can control the movement of the connecting member 330 through the nut assemblies 430, thereby adjusting the distance between the pressure member 300 and the rolling disc 200, and realizing the control of the squeezing process of fruits and vegetables.

[0036] At least one nut assembly 430 is provided with a plurality of adjustment parts 4311 on its circumference, and the adjustment parts 4311 are used to provide a more precise adjustment function to ensure more precise lifting and lowering control of the connecting member 330. The position of the nut 431 assembly 430 in the axial direction of the screw rod 420 can be adjusted through the adjustment parts 4311, thereby adjusting the position of the connecting member 330 connected to the corresponding screw rod 420, and further adjusting the inclination of the pressing surface of the corresponding pressure bearing member 300 or the rolling plate 200 to ensure the pressing effect of the juice extractor 10.

[0037] Specifically, the connection member 330 is provided on the pressure member 300 as an example for explanation. The position of the connection member 330 in the axial direction of the screw rod 420 is closely related to the nut assembly 430. During the production and assembly process of the juicer 10, there may be an error in the height of the nut assembly 430 on each screw rod 420, or after the juicer 10 is used for a long time, the accumulated error of the moving stroke of the nut assembly 430 on each screw rod 420 leads to different heights of the nut assemblies 430, thereby causing the pressing surface of the pressure member 300 to tilt, affecting the pressing effect of the juicer 10.

[0038] When the pressing surface of the pressure-bearing member 300 is tilted, the distance that the nut assembly 430 needs to move in the axial direction of the screw rod 420 is obtained according to the degree of tilt, and then the moving distance is converted into the number of rotations of the nut assembly 430, and the number of the adjusting parts 4311 that need to be rotated is obtained according to the total number of adjusting parts 4311 on the circumference of the nut assembly 430. The position of the nut assembly 430 on the screw rod 420 can be fine-tuned by the adjusting parts 4311, so that the position of the connecting member 330 on the screw rod 420 can be adjusted, so that the position of the connecting member 330 on each screw rod 420 is at the same height, thereby avoiding the tilt of the pressing surface of the pressure-bearing member 300, so as to ensure the squeezing effect of the juicer 10. The same is true when the connecting member 330 is set on the rolling plate 200, which will not be repeated here.

[0039] The adjusting portion 4311 may be a protrusion, a groove, or a scale mark, etc., which is not limited here.

[0040] In one embodiment, the nut assembly 430 includes an adjusting nut 431 and a flange 432 connected to each other. The flange 432 is connected to the connecting member 330 . The adjusting nut 431 is disposed in the mounting hole 331 . The adjusting nut 431 is provided with a plurality of adjusting portions 4311 on its circumference.

[0041] Please refer to Figures 2 to 4 The nut assembly 430 includes an adjusting nut 431 and a flange 432 connected to each other. The adjusting nut 431 is sleeved on the screw rod 420 and is threadedly adapted to the screw rod 420. The adjusting nut 431 is arranged in the mounting hole 331 of the connecting member 330. The adjusting nut 431 is connected to the connecting member 330 through the flange 432. By rotating the adjusting nut 431, the position of the nut assembly 430 on the screw rod 420 can be fine-tuned. The adjusting nut 431 is provided with a plurality of adjusting parts 4311 on its circumference. The adjusting parts 4311 are used to provide a more precise adjustment function to ensure that the lifting and lowering control of the connecting member 330 can be achieved more accurately. In other embodiments, the adjusting parts 4311 can also be arranged on the circumference of the flange 432. Through the adjusting parts 4311 on the flange 432, the nut assembly 430 can also be fine-tuned more accurately to achieve the consistency of the height position of the connecting member 330 on each screw rod 420.

[0042] In one embodiment, a plurality of limiting grooves 4312 extending along the axial direction of the screw rod 420 are provided at intervals on the outer peripheral wall of the adjusting nut 431 , and an adjusting portion 4311 is formed between two adjacent limiting grooves 4312 .

[0043] Please refer to Figure 3 , the adjustment portion 4311 is formed by two adjacent limiting grooves 4312. Compared with the adjustment portion 4311 formed by the circumferential side wall protrusion of the adjustment nut 431, the design of forming the adjustment portion 4311 between two adjacent limiting grooves 4312 makes the radial dimension of the adjustment nut 431 smaller and more convenient to process. A limiting groove 4312 and an adjacent adjustment portion 4311 can be used as an adjustment unit. According to the arc length of the adjustment unit, it can be obtained that the distance that the connecting member 330 moves on the screw rod 420 for each rotation of an adjustment portion 4311. The length of the limiting groove 4312 in the circumferential direction of the adjustment nut 431 can be the same as or different from the length of the adjustment portion 4311 in the circumferential direction of the adjustment nut 431.

[0044] In one embodiment, the lifting mechanism 400 further includes a fastener, the connecting member 330 is provided with a limiting hole 332 communicating with the mounting hole 331 , the fastener passes through the limiting hole 332 and abuts against the limiting groove 4312 .

[0045] Please refer to Figure 3 and Figure 4 The limiting groove 4312 also has the function of limiting the movement of the adjusting nut 431 on the screw rod 420. The lifting mechanism 400 also includes a fastener (not shown in the figure), which is used to fix the connecting member 330 and the adjusting nut 431. The connecting member 330 is provided with a limiting hole 332 connected to the mounting hole 331. The fastener passes through the limiting hole 332 and abuts against the limiting groove 4312 to ensure a stable connection between the connecting member 330 and the adjusting nut 431.

[0046] After the nut assembly 430 is positioned by the adjusting portion 4311, the flange 432 needs to be connected to the connector 330. During the operation of connecting the flange 432 to the connector 330, an error may occur, causing the adjusting nut 431 to rotate, resulting in an error in the position of the nut assembly 430 that has just been adjusted. Therefore, the connector 330 and the adjusting nut 431 can be firmly connected by fasteners to ensure that the adjusting nut 431 does not rotate during the operation of connecting the flange 432 to the connector 330, so that the position of the adjusting nut 431 on the screw rod 420 is limited, thereby ensuring that the adjustment of the nut assembly 430 is effective.

[0047] In one embodiment, the flange 432 is disposed at one axial end of the adjusting nut 431 , and a side surface of the flange 432 close to the adjusting nut 431 in the axial direction abuts against the connecting member 330 .

[0048] Please refer to Figure 3 The adjusting nut 431 is arranged in the mounting hole 331, and the flange 432 is arranged at one end of the adjusting nut 431 in the axial direction. The flange 432 can be arranged above the adjusting nut 431 or below the adjusting nut 431. The flange 432 is in contact with the connecting member 330 on one side thereof close to the adjusting nut 431 in the axial direction, that is, the flange 432 is arranged outside the mounting hole 331, so as to facilitate the disassembly and connection of the flange 432 and the connecting member 330. The adjusting nut 431 is connected to the connecting member 330 through the flange 432, so as to ensure that the rotation of the adjusting nut 431 on the screw rod 420 is limited, so as to control the lifting and lowering of the rolling disc 200 or the pressure-bearing member 300.

[0049] In one embodiment, the connecting member 330 is disposed on the side wall of the pressure-bearing member 300 , and the lifting mechanism 400 further includes a driving member 410 , a screw rod 420 extending in a vertical direction, and the driving member 410 drives the connecting screw rod 420 to drive the pressure-bearing member 300 to move up and down.

[0050] Please refer to Figure 4The connecting member 330 is disposed on the side wall of the pressure bearing member 300, ensuring a firm connection between the connecting member 330 and the pressure bearing member 300. The driving member 410 is used to provide power for the rotation of the screw rod 420, so that the juice extractor 10 can realize the up and down movement of the pressure bearing member 300 through the rotation of the screw rod 420, thereby controlling the squeezing degree of the squeezed material and the juice extraction efficiency.

[0051] It can be understood that a squeezing space is formed between the rolling disc 200 and the pressure member 300, and the squeezed material is confined in the squeezing space. When the lifting mechanism 400 drives the pressure member 300 to move upward, the pressure member 300 approaches the rolling disc 200, and the squeezed material is squeezed under the pressure of the pressure member 300 and the rolling disc 200; when the juicing is completed, the lifting mechanism 400 drives the pressure member 300 to move downward, and the pressure member 300 is away from the rolling disc 200, so as to remove the residue and place new squeezed material.

[0052] In one embodiment, the pressure-bearing member 300 includes a support seat 310 and a filter screen 320 . The filter screen 320 is disposed between the support seat 310 and the rolling disc 200 and is connected to the support seat 310 . A juice storage space is formed between the filter screen 320 and the support seat 310 . The connecting member 330 is disposed on the side wall of the support seat 310 .

[0053] Please refer to Figure 2 In 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 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 solid particles in fruits and vegetables, ensuring that the squeezed juice is pure in quality and tastes better. As an important component of the pressure-bearing member 300, the support seat 310 can not only stably support the filter 320, but also provide an installation position for the connecting member 330, so as to realize up and down movement under 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.

[0054] The juicer 10 also includes a juice box, which is designed to be pullable in the juice storage space. The user can easily pull out the juice box to pour out the stored juice or perform cleaning and maintenance, so that the user can handle the juice more conveniently when using the juicer 10, thereby improving the user experience and operational convenience.

[0055] In one embodiment, a reinforcing rib 333 is disposed on the outer surface of the connecting member 330 , and the reinforcing rib 333 is connected to the side wall surface of the supporting seat 310 .

[0056] Please refer to Figure 4, the outer surface of the connector 330 is provided with reinforcing ribs 333, and the reinforcing ribs 333 are used to enhance the structural strength and stability of the connector 330. The reinforcing ribs 333 are connected to the side wall surface of the support seat 310, ensuring a firm connection between the connector 330 and the support seat 310, while also increasing the overall stability of the connector 330. Through the design of the reinforcing ribs 333, the connector 330 can transmit and disperse pressure and force more evenly when subjected to pressure and force, reducing the risk of deformation and damage of the connector 330. The design of the reinforcing ribs 333 connected to the side wall surface of the support seat 310 makes the connection between the connector 330 and the support seat 310 more secure, ensuring the stability and reliability of the juicer 10 during operation.

[0057] In one embodiment, the connecting member 330 and the supporting base 310 are integrally formed.

[0058] The connector 330 and the support base 310 can be integrally formed by injection molding or by metal casting. The connector 330 and the support base 310 are integrally formed, which means that they are manufactured as a whole component, rather than being manufactured separately and then assembled together, so that the connection between the connector 330 and the support base 310 is more firm and stable, avoiding problems caused by improper assembly or loose connection.

[0059] In one embodiment, there are two nut assemblies 430 and two screw rods 420, and the two screw rods 420 are arranged on two opposite sides of the support seat 310. The two nut assemblies 430 are arranged on the two screw rods 420 in a one-to-one correspondence, and one of the nut assemblies 430 is provided with multiple adjustment parts 4311 on its circumference.

[0060] Please refer to Figure 2 , two nut assemblies 430 and screw rods 420 are provided, which are respectively installed on the opposite sides of the support seat 310, so that the lifting mechanism 400 of the juicer 10 is more stable and balanced, and can better support and control the lifting movement of the pressure-bearing member 300, and also enhance the stability and reliability of the juicer 10, ensuring its long-term stable operation. At the same time, the setting of the adjustment part 4311 makes the operation of the juicer 10 more accurate and convenient. It only needs to be provided with an adjustment part 4311 on the circumference of one of the nut assemblies 430 to adjust the inclination of the pressure-bearing member 300, which not only simplifies the operation of adjusting the nut 431 assembly 430, but also simplifies the processing of the other nut assembly 430, reducing the production cost.

[0061] In one embodiment, the frame 100 includes a plurality of guide shafts 130 extending in the vertical direction, and a first mounting plate 110 and a second mounting plate 120 respectively arranged at both ends of the screw rod 420, the guide shaft 130 passes through a support seat 310, and the two ends of the guide shaft 130 are respectively connected to the first mounting plate 110 and the second mounting plate 120; the first mounting plate 110 is arranged above the second mounting plate 120, the pressure-bearing member 300 and the rolling plate 200 are arranged between the first mounting plate 110 and the second mounting plate 120, and the driving member 410 and the rolling plate 200 are arranged on the first mounting plate 110.

[0062] 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 disc 200 are arranged in the installation space. The rolling disc 200 is relatively fixed to a side of the first mounting plate 110 facing the second mounting plate 120. The pressure-bearing member 300 and the rolling disc 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 juicing fruits and vegetables of different sizes. At the same time, the installation of the driving member 410 and the rolling disc 200 on the first mounting plate 110 simplifies the mechanical structure and improves the driving efficiency and the overall performance of the juicer 10.

[0063] The frame 100 further includes a plurality of guide shafts 130, which extend in the vertical direction and pass through the support base 310 to enhance the stability and load-bearing capacity of the frame 100. The provision 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.

[0064] 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.
