As shown in fig. 7-8, the screw 5 for the juicer in the application comprises a screw body 51 and a screw 52 arranged on the screw body 51, and materials are extruded and crushed under the action of the screw 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 more than or equal to 1.25 and less than or equal to 3.5, so that the diameter of the screw 52 at the top of the screw 5 is the largest, a good biting effect can be realized to the greatest extent, and the materials can be effectively and primarily crushed. 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 contour of the screw rod. The screw 5 is gradually reduced from the upper end to the lower outer diameter, so that the average diameter of the screw 5 is reduced, the load is reduced, and the motor can effectively drive the screw 5 without setting larger power, so that the screw 5 can stably run. Simultaneously, the motor torque is reduced, the power is reduced, and the volume can be reduced. The screw 5 and the motor are miniaturized, so that the screw is more convenient for users to carry, and the production cost is reduced. If the ratio of the outer diameter of the upper end of the screw 5 to the outer diameter of the lower end is smaller than 1.25, the average diameter of the screw 5 is still larger, the load of the screw 5 is higher, the load of a required motor is correspondingly increased, the volumes of the screw 5 and the motor are larger, the screw 5 is inconvenient to take and carry, and meanwhile, the production cost is higher; if the ratio of the outer diameter of the upper end of the screw 5 to the outer diameter of the lower end of the screw 5 is greater than 3.5, the difference between the outer diameter of the lower end of the screw 5 and the outer diameter of the upper end is too large, and a large blanking gap exists between the screws 52 at the upper end and the lower end of the screw 5 in the longitudinal direction, the material primarily crushed by the screws 52 at the upper end of the screw 5 is likely to not be fully extruded by the screws 52 at the lower end and directly fall to the bottom of the screw 5, so that the crushing efficiency is low. Preferably, a/b is 1.5.ltoreq.3.25, in this example, a is 70mm and b is 30mm.

The screw 5 comprises a biting section and an extrusion section from top to bottom, the materials are firstly crushed preliminarily through the biting section, the large materials are crushed into small materials, the small materials enter the extrusion section along with the small materials, further grinding and crushing are carried out under the action of the extrusion section, the angle formed by the connecting line between the maximum rotating outer contour and the minimum outer contour of the biting section and the axis of the screw 5 is alpha, and the angle alpha is more than or equal to 20 degrees and less than or equal to 35 degrees, so that the materials are firstly cut into small materials by the spiral 52 with the maximum outer diameter on the biting section, and at the moment, the small materials can obtain larger spiral propelling force and can be effectively conveyed to other spirals 52 of the biting section for further crushing. If alpha is smaller than 20 degrees, the diameters of the maximum rotation outer contour and the minimum rotation 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 smaller, materials are easily accumulated in the biting section and cannot smoothly enter the extrusion section, blanking is not smooth, and juice outlet efficiency is reduced; if α >35 °, the diameter difference between the maximum rotation outer contour and the minimum rotation outer contour of the biting section is too large, and since the blanking gap formed between the spirals 52 of the biting section in the longitudinal direction is too large, the material is cut by the spiral 52 having the maximum outer diameter, and then cannot be sufficiently ground again by the other spirals 52 of the biting section, resulting in a decrease in juice extraction efficiency.

The radius of rotation on the top end of the biting section is R1, and R1 is more than or equal to 30mm and less than or equal to 50mm, so that when materials enter the screw 5 for extrusion, the materials can be completely surrounded by the radius of rotation on the top end of the biting section for preliminary crushing, and the problems of unsatisfactory preliminary crushing effect and unsmooth blanking caused by accumulation of large materials on the biting section are avoided. R1 is too small, and the materials cannot be pre-crushed after entering the biting section, so that large materials cannot be cut into small pieces to be extruded, and the crushing efficiency is reduced; the overlarge R1 can cause the whole volume of the screw 5 to become large, the motor is correspondingly increased, portability is not facilitated, and meanwhile, the cost is increased.

The spiral 52 comprises a main spiral 521 arranged on the biting section, the main spiral 521 extends downwards from the top end of the biting section to the bottom end of the extrusion section, the height of the biting section is H1, H1 is less than or equal to 15mm and less than or equal to 35mm, so that materials are subjected to preliminary crushing in a sufficient space, if the H1 is too small, large materials cannot be cut into small pieces in the biting section, juice yield efficiency is reduced, if the H1 is too large, the running time of the materials in the biting section is too long, time lag of the materials entering the extrusion section is caused, and the situation that the materials are accumulated on the biting section and the spiral 52 on the extrusion section idles occurs.
