Technical Field

[0001] The utility model relates to the technical field of manufacturing small household appliances, in particular to a separating screw with metal mesh holes for a juicer. Background Art

[0002] As people's living standards improve, more and more people choose to use juicers to process food, which greatly saves the time and manpower required for cooking and makes people's lives more convenient.

[0003] A juicer is a machine that can quickly squeeze fruits and vegetables into juice and is widely used in restaurants, homes, and other places. The main functions of a juicer are juicing and filtering, wherein juicing is achieved by the rotation of the screw.

[0004] The screw receives rotational force from the drive unit and rotates to squeeze or crush the juiced food placed inside the juicing barrel. The food is pressed into the narrow gap between the screw and the mesh barrel by the screw threads formed on its side and conveyed downward. The screw is the main component that directly squeezes or crushes the juiced food.

[0005] The filter separates the chopped juice and pulp and then flows into the juice collecting barrel through the mesh of the filter to achieve solid-liquid separation.

[0027] Please refer to Figure 1 -6.

[0028] This embodiment provides a separation screw with a metal mesh for a juicer, including a central axis 1 located at the center of the screw filter. Figure 6, a groove ring 2 is provided on the central shaft 1, and the groove ring 2 is two and is distributed at a small distance. The design layout of the two groove rings 2 can better fix the upper cover 3 when the upper cover 3 is fixed to the central shaft 1 through the injection molding process, forming an integrated structure to prevent the upper cover 3 from shaking. The central shaft 1 is provided with a step portion 4, which is used to place the gasket 16 and the blade 13 (please refer to Figure 2 ), press the blade 13 with the nut 14, and then put the screw 15 into the threaded hole 17 on the head of the central shaft 1 to fix the blade 13. The blade 13 is used to pre-cut the fruits and vegetables into small pieces for easy squeezing.

[0029] In the embodiments of the present invention, please refer to Figure 3 The upper cover 3 is evenly provided with 16 opening teeth 5, which are inserted into the opening grooves 7 of the screw part 6 to achieve a fixed connection between the screw part 6 and the upper cover 3. Similarly, 16 opening grooves 7 are also designed, and the two are interference fit.

[0030] In the embodiments of the present invention, please refer to Figure 4 The screw portion 6 is provided with an upper seat ring 8 and a base ring 9, and the upper seat ring 8 and the base ring 9 are fixedly connected in an integral manner by means of columns 10 evenly arranged along the circumference. The outer ring of the columns 10 is integrally provided with spiral pressing threads 11, which are 8 in number, parallel to each other and at equal intervals, starting from the upper seat ring 8 of the screw portion 6 and ending at the base ring 9 of the screw portion 6.

[0031] A metal filter 12 is integrally provided in the pressing screw thread 11 near the side of the column 10 , and the height of the metal filter 12 is greater than the height of the column 10 .

[0032] In the embodiment of the present invention, the mesh size of the metal filter 12 is 0.6 mm. The mesh size takes into account the balance between the effect of filtering juice and the effect of cleaning the filter. The mesh size of the metal filter 12 is 0.6 mm, which is the most suitable.

[0033] Furthermore, the upper cover 3 is provided with a squeezing screw 11. Since the upper cover 3 has a large contact area, more squeezing screws 11 are provided to achieve a better squeezing effect on the fruits.

[0034] Furthermore, the uprights 10 are evenly distributed circumferentially in a grid-like manner so that the force is evenly distributed and no dynamic balance problem or shaking occurs during rotation.

[0035] The beneficial effect of the present invention lies in the fact that a metal filter 12 is integrally installed within the squeezing screw 11 near the side of the column 10, and the height of the metal filter 12 is greater than that of the column 10, thereby integrating the metal filter and the screw into one. As the pulp is squeezed, the resulting juice flows out of the metal filter. Specifically, the chopped pulp and juice flow through the mesh of the metal filter 12 into the juice collecting chamber 18, achieving separation of pulp and juice. Because the metal filter 12 blocks the entry of fine pulp or pomace into the juice, the juice has a better taste.
