Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of juice extraction, and in particular relates to a cold-pressed juice extractor. Background Art
[0002] Fruits and vegetables are the main foods for the human body to take in vitamins. Studies have shown that people who often eat fruits and vegetables are in better health than those who do not like to eat fruits and vegetables. In particular, fruits and vegetables have an irreplaceable role in preventing diseases and are indeed a good choice for a healthy diet. Although fruits and vegetables are rich in nutrients, many people do not like to eat them directly, so many families are equipped with juicers to solve health problems. The power mode of existing juicers is that the motor drives the spiral extrusion or blade cutting. The high-speed rotating blades crush the fruits and vegetables and then centrifuge them. The fruits and vegetables are pushed from the feeding port to the knife net. The sharp thorns of the knife net cut the fruits and vegetables. Under the action of the centrifugal force of the juicer generated by the high-speed operation of the knife net, the pomace flies out of the knife net and enters the pomace box, while the juice passes through the knife net and flows into the juice cup. When the above two juicing methods are actually used, they will cause local high temperature during the juicing process, resulting in the loss of nutrients in the fruits and vegetables. In addition, as the juicing movement proceeds, the oxidation time will also increase, thereby destroying the taste of the juice. Utility Model Content

[0029] Reference Figure 1-5 As shown, a cold press juicer comprises
[0030] The driving mechanism comprises: a motor 1; a screw rod 100 arranged on the driving shaft of the motor 1; and two stretching nuts 3 sleeved on the screw rod 100 and arranged at intervals.
[0031] A stretching nut 3 is positioned and connected to one end of the screw rod 100 and is rotatably connected to the bearing of the screw rod 100 .
[0032] The lower end extension nut 3 is positioned and connected to the screw rod 100, and can be connected to the screw rod 100 through an interference fit bearing, or can be fixedly connected to the motor 1, and the screw rod 100 passes through the extension nut 3, so as not to affect the rotation of the screw rod 100. The upper end extension nut 3 is positioned and connected to the screw rod 100, and can only be connected to the screw rod 100 through an interference fit bearing, so as to ensure that the position of the screw rod 100 and the extension nut 3 remains unchanged, and does not affect the rotation of the screw rod 100.
[0033] The outer frame includes a rear support plate 2 , two first guide rods 6 arranged in parallel on the upper portion of the rear support plate 2 , and two second guide rods 60 arranged in parallel on the lower portion of the rear support plate 2 .
[0034] The transmission mechanism comprises: two groups of symmetrically arranged connection components, each of which comprises a first fixed rod 50 and a second movable rod 5 which are arranged in parallel on the guide rod; a first hinge member 32, a second hinge member 33, a third hinge member 34, a fourth hinge member 35, a first connecting rod 30 and a second connecting rod 31; the first connecting rod 30 and the second connecting rod 31 are symmetrically arranged at both ends of each stretching nut 3; the two ends of the first hinge member 32 are respectively hinged between the first fixed rod 50 and the first connecting rod 30, and the two ends of the second hinge member 33 are respectively hinged between the second movable rod 5 and the first connecting rod 30; the two ends of the third hinge member 34 are respectively hinged between the first fixed rod 50 and the second connecting rod 31, and the two ends of the fourth hinge member 35 are respectively hinged between the second movable rod 5 and the second connecting rod 31.
[0035] Among them, the motor 1 drives the screw 100 through a key connection, converts the rotational torque into a moving torque and amplifies the force. The screw 100 is a key component for converting rotational motion into linear motion. The thread on it interacts with the stretch nut 3. At the same time, the first hinge member 32, the second hinge member 33, the third hinge member 34 and the fourth hinge member 35 limit the rotational freedom of the stretch nut 3, allowing it to move linearly, and the first hinge member 32, the second hinge member 33, the third hinge member 34 and the fourth hinge member 35 can change the direction of the force or Provide additional torque. Under the rotation of the screw 100, the stretch nut 3 moves up and down along the screw axis. The threads of the screw 100 and the stretch nut 3 cooperate to convert the rotation torque of the screw 100 into the linear displacement of the stretch nut 10. According to the principle of the scissor jack, a plurality of first hinge parts 32, second hinge parts 33, third hinge parts 34 and fourth hinge parts 35 with teeth work together to convert the torque into the linear displacement of the second moving rod 5. The second moving rod 5 receives the torque from the first hinge parts 32, the second hinge parts 33 , the third hinge member 34 and the fourth hinge member 35, and drives the pressing shaft connecting block 8 and the pressing shaft 11 through its linear displacement, and the pressing shaft connecting block 8 is connected to the two moving rods 5, and transmits the linear motion to the pressing shaft 10. The pressing shaft 10 physically squeezes the fruit in the pressing barrel 9 under the action of linear displacement. At the same time, the free ends of the first guide rods 6 and the second guide rods 60 are connected to a bearing relay plate 13, and a bearing frame 12 for wrapping and fixing the pressing barrel 9 is fixedly provided on the bearing relay plate 13. The pressing barrel 9 is fixedly provided with a support plate 10, and the support The plate 10 is threadedly connected to the supporting frame 12; the rear receiving plate 2, the second moving rod 5, the first guide rod 6, the second guide rod 60, the first fixed rod 50, the bearing relay plate 13, the support plate 10 and the supporting frame 12 are combined to form an enclosed frame for improving the stability of the cold-pressed juicer. Thus, the above structures are combined to form a new type of cold-pressed juicer, which can not only more effectively extract moisture from fruits and improve the juice yield, but also because the juice has less contact with air during the cold-pressed juicing process, less foam is generated, making the squeezed juice clearer.
[0036] Furthermore, cold pressing technology operates at low temperatures, which can minimize the oxidation of juice during the squeezing process, thereby better preserving nutrients such as vitamins, minerals and enzymes in the fruit. And because cold-pressed juicing does not involve high-speed rotating blades, it does not generate heat due to friction, which helps to maintain the natural flavor of the juice and make the taste purer and richer. Secondly, because it does not rely on electric motors and blades, cold-pressed juicers are quieter in operation, providing a more comfortable user experience. Finally, cold-pressed juicers are suitable for squeezing fruits and vegetables of various hardness, including those that contain more fiber or are more difficult to juice, and are widely used.
[0037] The pressing shaft connecting block 8 is fixedly arranged on the second moving rod 5, and the pressing shaft connecting block 8 is pushed to press the fruits and vegetables through the power mechanism; a make way groove 80 for making way for the second hinge member 33 and the fourth hinge member 35 is formed on the pressing shaft connecting block 8; the pressing shaft connecting block 8 has one end, which extends into the interior of the pressing barrel 9 and is connected to a pressing shaft 11.
[0038] Furthermore, the integrated design of the motor 1, the screw 100, the stretching nut 3, the pressing shaft connecting block 8 and the pressing shaft 11 provides a more compact and efficient juice extraction solution. At the same time, the solution simplifies the maintenance and operation process, which not only reduces costs but also improves work efficiency.
[0039] The first hinge member 32, the second hinge member 33, the third hinge member 34 and the fourth hinge member 35 are all provided with teeth, and the first hinge member 32, the second hinge member 33, the third hinge member 34 and the fourth hinge member 35 which are arranged relatively to each other are meshed and linked through the teeth to avoid displacement during movement, while ensuring the consistency of movement and balancing the forces between the first hinge member 32, the second hinge member 33, the third hinge member 34 and the fourth hinge member 35, so that the pressing shaft connecting block 8 can squeeze juice more smoothly.
[0040] The fixed ends of the first guide rods 6 and the second guide rods 60 are threadedly connected with a lock nut 61, and the outer walls of the first guide rods 6 and the second guide rods 60 are provided with sliding guide sleeves 62, and the sliding guide sleeves 62 are embedded in the holes opened on the second moving rod 5 to assist the second moving rod 5 in translational sliding.
[0041] Furthermore, the sliding guide sleeve 62 can reduce the friction between the first guide rod 6 and the second guide rod 60 and the second movable rod 5, thereby reducing energy consumption and improving mechanical efficiency. The use of the first guide rod 6 and the second guide rod 60 in conjunction with the sliding guide sleeve 62 can ensure that the second movable rod 5 performs precisely controlled translational sliding along a specific direction. At the same time, the first guide rod 6 and the second guide rod 60 are fixed by the lock nut 61, which increases the stability of the entire system and prevents displacement or bending under high loads. Furthermore, due to the use of threaded connection and sliding guide sleeve design, the installation, adjustment and maintenance of the components become relatively simple. Therefore, good guiding and low-friction sliding help to extend the service life of the machine because they reduce wear.
[0042] The above description is only the preferred implementation of the utility model, and is not intended to limit the utility model. For those skilled in the art, the utility model can have various modifications and changes. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the utility model shall be included in the protection scope of the utility model.
