Description

Technical Field

[0001] The present invention relates to the technical field of juicing equipment, and more particularly to a juicer. Background Art

[0002] Juicers can process fruits, vegetables, etc. into delicious beverages and have always been popular among people. With the improvement of people's living standards, juicers have moved from beverage stores to the kitchens of thousands of households and become an essential helper for people to enhance their quality of life.

[0003] Juicers usually allow relatively large pieces of fruits, vegetables and other materials to be directly placed into the pressing barrel, and then the juicing operation can be carried out. However, many fruits and vegetables are relatively hard or have strong toughness, and it is difficult to carry out efficient juicing through a juicer. Therefore, how to improve the juicing efficiency of juicers has always been a problem for R & D personnel in this industry to think about. Summary of the Invention

[0004] The purpose of the present invention is to provide a juicer to solve the technical problem of improving the juicing efficiency of the juicer.

[0005] To achieve the above object, the technical solution adopted by the present invention is: to provide a juicer, including: a base, a pressing cup and a pressing barrel. The pressing cup is installed on the base, the pressing barrel is installed on the pressing cup, a pressing component is arranged in the pressing cup, the pressing component includes a pressing moving component and a pressing static component, the pressing moving component and the pressing static component rotate relative to each other, a pre-cutting component is arranged above the pressing component, the pre-cutting component includes a pre-cutting knife and a pre-cutting stopper, the pre-cutting knife and the pre-cutting stopper rotate relative to each other, the pre-cutting knife extends from inside the pressing cup into the pressing barrel, and the pre-cutting stopper is arranged at the lower part of the pressing barrel and protrudes into the pressing barrel.

[0006] In the juicer of the present invention, by arranging the pre-cutting component, the pre-cutting knife and the pre-cutting component form a shear to pre-cut large pieces of materials first, and then the materials are pressed by the pressing component, greatly improving the pressing efficiency. At the same time, the pre-cutting knife extends from inside the pressing cup into the pressing barrel. While pre-cutting the materials, it can also effectively stir the materials in both the pressing cup and the pressing barrel.

[0007] Preferably, the pre-cutting knife is fixed on the pressing moving component. The pre-cutting knife is directly driven by the pressing moving component to rotate, without separately transmitting power to the pre-cutting knife, reducing power loss and improving the juicing efficiency.

[0008] More preferably, the above-mentioned pre-cutting stopper is fixed below the pressing barrel. The pre-cutting stopper can extend into the pressing barrel from the bottom of the pressing barrel, or can directly extend into the pressing barrel from the inner wall of the pressing barrel. The shape of the pre-cutting stopper can be a U-shaped convex upward, or other shapes such as a triangle. The pre-cutting stopper cooperates with the rotation of the pre-cutting knife to effectively shear the material and can effectively cut large pieces of material.

[0009] More preferably, the above-mentioned pressing moving component is the first pressing net, and the pressing static component is the first pressing rod arranged inside the first pressing net. On the one hand, the first pressing net cooperates with the first pressing rod to press the material, and on the other hand, it drives the pre-cutting knife to cooperate with the pre-cutting stopper to shear the material, effectively improving the pressing efficiency.

[0010] More preferably, the above-mentioned pressing moving component is the first pressing screw, and the pressing static component is the second pressing net arranged around the first pressing screw. On the one hand, the first pressing screw cooperates with the second pressing net to press the material, and on the other hand, it drives the pre-cutting knife to cooperate with the pre-cutting stopper to shear the material, effectively improving the pressing efficiency.

[0011] Preferably, the above-mentioned pre-cutting stopper is fixed on the pressing moving component and rotates together with the pressing moving component. The pre-cutting stopper rotates relative to the pre-cutting knife, passes above and / or on the side of the pre-cutting knife, shears the material, and stirs the material in the pressing barrel, improving the pressing efficiency. The pre-cutting stopper can be U-shaped or other shapes such as strip-shaped.

[0012] More preferably, the above-mentioned pressing moving component is the third pressing net, and the pressing static component is the second pressing rod arranged inside the third pressing net. On the one hand, the third pressing net cooperates with the third pressing rod to press the material, and at the same time, the pre-cutting stopper cooperates with the pre-cutting knife to shear the material.

[0013] More preferably, the above-mentioned pre-cutting knife is fixed at the top of the second pressing rod. The pre-cutting knife is fixed at the top of the second pressing rod and extends into the pressing barrel. Although the pre-cutting knife does not move, due to the rotation of the pre-cutting stopper, it can still shear the material well. At the same time, due to the feeding from above or on the side of the pre-cutting knife, it can effectively improve the stirring effect on the material.

[0014] More preferably, fixing feet are arranged at the upper part of the third pressing net, and the fixing feet are coupled and connected with the pre-cutting stopper, and the pre-cutting stopper drives the third pressing net to rotate. The third pressing net is driven by the pre-cutting stopper, and the pre-cutting stopper is directly powered by a power mechanism in the base. The above design makes the power of the pre-cutting stopper stronger and the efficiency of stirring and shearing the material higher.

[0015] More preferably, the squeezing moving component is a second squeezing screw, and the squeezing static component is a fourth squeezing screen arranged around the second squeezing screw. On the one hand, the second squeezing screw cooperates with the fourth squeezing screen to squeeze the material. On the other hand, the squeezing stopper and the pre-cutting knife rotate relative to each other to shear the material, improving the juice extraction efficiency.

[0016] More preferably, the pre-cutting knife is fixed in the squeezing cup and extends into the range of the pre-cutting stopper. The pre-cutting knife extends from the inside of the squeezing cup into the squeezing barrel, which can effectively stir and shear the material in the squeezing barrel, improving the juice extraction efficiency.

[0017] Preferably, the minimum clearance between the pre-cutting knife and the pre-cutting stopper is greater than or equal to 0.3 mm. When the clearance is less than 0.3 mm, the pre-cutting knife and the pre-cutting stopper are prone to interference and collision during rotation, resulting in damage.

[0018] Preferably, at least a part of at least one of the pre-cutting knife and the pre-cutting stopper is made of metal. The pre-cutting knife and / or pre-cutting stopper made of at least metal can improve the sharpness, enhance the shearing efficiency of the material, and at the same time reduce the wear of the pre-cutting knife and / or pre-cutting stopper, increasing the service life.

[0019] Preferably, the pre-cutting knife has a cutting edge. The pre-cutting knife is sharpened, which can greatly improve the shearing efficiency of the material, reduce the force on the pre-cutting knife and the pre-cutting stopper, and increase the service life.

[0020] More preferably, the cutting edge is serrated. The serrated design of the cutting edge can better shear the material. Since the force application point of the material becomes smaller, it is easier to cut large pieces of material.

[0021] Preferably, a fixing device is arranged between the squeezing moving component and the squeezing barrel to prevent the squeezing moving component from disengaging downward from the squeezing barrel. The design of the fixing device enables the squeezing moving component to be removed together with the squeezing barrel, facilitating cleaning.

[0022] Preferably, the height of the pre-cutting knife is greater than or equal to 25 mm. When the height of the pre-cutting knife is lower than 25 mm, it is difficult to extend into the squeezing barrel or the inserted size is too small, resulting in limited stirring effect on the material.

[0023] Preferably, the overlapping dimension between the pre-cutting knife and the pre-cutting stopper is greater than or equal to 15 mm. When the pre-cutting knife and the pre-cutting stopper intersect during rotation, the range where both pass through is the overlapping range, and the dimension in the length direction of this overlap needs to be greater than or equal to 15 mm. If this dimension is less than 15 mm, the shearing range is too small, and it is difficult to form high-efficiency shearing of the material.

[0024] Preferably, the closest distance between the above-mentioned pre-cutting knife and the inner wall of the pressing barrel is less than or equal to 15 mm. When the distance between the pre-cutting knife and the inner wall of the pressing barrel is greater than 15 mm, the pre-cutting knife is too close to the center of the pressing barrel, which is not conducive to the pre-cutting and pressing of large-sized materials.
