As shown in fig. 7-8, the screw 5 for the juice extractor in the present application includes a screw body 51 and a spiral 52 disposed on the screw body 51, and the material is extruded and pulverized under the action of the spiral 52, wherein the rotating outer diameter of the upper end of the screw 5 is a, the rotating outer diameter of the lower end of the screw 5 is b, and a/b is greater than or equal to 1.25 and less than or equal to 3.5, so that the diameter of the spiral 52 at the top of the screw 5 is the largest, a good biting effect can be achieved to the greatest extent, and the material is effectively primarily pulverized. Wherein, the rotating outer diameters of the upper end and the lower end of the screw rod refer to the outer diameter of the rotating outer profile of the screw rod. The screw rod 5 is reduced gradually from the upper end to the lower outer diameter, so that the average diameter of the screw rod 5 is reduced, the load is reduced, the motor can effectively drive the screw rod 5 without setting large power, and the screw rod 5 can stably run. Meanwhile, the torque of the motor is reduced, the power is reduced, and the size can be reduced. The screw rod 5 and the motor are both miniaturized, so that the screw rod is more convenient for a user to carry, and the production cost is also reduced. If the ratio of the outer diameter of the upper end of the screw rod 5 to the outer diameter of the lower end of the screw rod 5 is less than 1.25, the upper outer diameter and the lower outer diameter of the screw rod 5 are not obviously changed, the average diameter of the screw rod 5 is still larger, the load of the screw rod 5 is higher, the load of a needed motor is correspondingly increased, the sizes of the screw rod 5 and the motor are larger, the taking and carrying are inconvenient, and meanwhile, the production cost is higher; if the external diameter ratio of the upper end of the screw rod 5 to the external diameter of the lower end of the screw rod 5 is larger than 3.5, the difference between the external diameter of the lower end of the screw rod 5 and the external diameter of the upper end of the screw rod is too large, a larger blanking gap exists between the screws 52 at the upper end and the lower end of the screw rod 5 in the longitudinal direction, and the possibility that the materials primarily crushed by the screws 52 at the upper end of the screw rod 5 cannot be fully extruded by the screws 52 at the lower end and directly fall.

If alpha is less than 20 degrees, the diameters of the maximum rotating outer contour and the minimum rotating outer contour of the biting section are not obviously changed, blanking gaps formed between the spirals 52 of the biting section in the longitudinal direction are small, materials are easy to accumulate in the biting section and cannot smoothly enter the extruding section, blanking is not smooth, and juice outlet efficiency is reduced; if alpha is more than 35 degrees, the diameter difference between the maximum rotating outer contour and the minimum rotating outer contour of the material biting section is too large, and the blanking gap formed between the spiral 52 of the material biting section in the longitudinal direction is too large, so that the material can not be fully ground again by other spiral 52 of the material biting section after being cut by the spiral 52 with the maximum outer diameter, and the juice outlet efficiency is reduced.

The radius of rotation on stinging material section top is R1, and 30mm is less than or equal to R1 and is less than or equal to 50mm for when the material gets into 5 extrusion of screw rod, can be surrounded by the radius of rotation on stinging material section top completely, carry out preliminary crushing, avoid bold material to pile up stinging the material section, cause the unsatisfactory and unsmooth problem of unloading of preliminary crushing effect. When the R1 is too small, the material cannot be pre-crushed after entering the material biting section, so that a large material cannot be cut into small pieces to be extruded, and the crushing efficiency is reduced; the R1 is too large, the whole volume of the screw rod 5 is increased, the motor is correspondingly increased, portability is not facilitated, and meanwhile, the cost is increased.

The spiral 52 is including setting up in the main spiral 521 that stings the material section, main spiral 521 is by stinging the material section top and down extending to the extrusion section bottom, it is H1 to sting the height of material section, 15mm is less than or equal to H1 and is less than or equal to 35mm for the material has abundant space to carry out preliminary crushing, if the undersize that H1 set up, bold material can't be cut into the fritter at stinging the material section, will lead to juice efficiency to reduce, if the oversize that H1 set up, the material is stinging the material section operation time overlength, will lead to the material to get into the time lag of extrusion section, the material piles up at stinging the material section, and the idle running situation of spiral 52 on the extrusion section appears.

The height of the main screw 521 on the material biting section is H2, the height H2 of the main screw 521 is the height of the main screw 521 protruding out of the surface of the screw body 51, the height H2 of the main screw 521 is set to be not less than 15mm and not more than H2 and not more than 25mm, so that the material can be completely covered by the rotating radius of the main screw 521 when entering the screw rod 5, the main screw 521 is ensured to firstly cut the material, the large material is changed into the small material to enter the extruding section, if the H2 is too small, the material cannot be cut by the main screw 521, the material is easily clamped, if the H2 is too large, the load of a motor is increased, meanwhile, the volume of the whole machine can be increased along with the whole machine, and the carrying is not convenient. The height of the spiral positioned at the extrusion section is H5, the height of the spiral 52 of the extrusion section protruding out of the surface of the screw body 51 is H5, H5 is arranged at 0.35mm or less and H5 or less and 15mm, so that a sufficient grinding gap is formed between the spirals 52 of the extrusion section in the longitudinal direction, small materials can be further ground to obtain juice under the action of the extrusion section, if H5 is arranged to be too small, the materials are easily rotated in the grinding gap and cannot be sufficiently ground, if H5 is arranged to be too large, the materials are easily accumulated in the grinding gap, and the grinding efficiency is reduced.
