AI Technical Summary
The continuous spiral design of the screw in traditional juice machines causes the material to be unable to be quickly and efficiently diverted to adjacent material downstream channels, affecting the juice squeezing efficiency.
A segmented screw is designed, with a spiral-shaped segmented extrusion rib strip in the outer wall of the screw along the circumferential direction, and a gap is set between the two adjacent extrusion strips to form a downstream channel of material.
Through the segmented design, when the pressure increases, the material can enter the adjacent material downstream channel through the gap between the adjacent two cutting extrusion strips, which improves the juice efficiency and avoids damage to the filter assembly due to excessive stress.

Abstract
Description
Technical Field
[0001] The utility model relates to a screw rod, more specifically, to a screw rod for a juicer and also to a juicer using the screw rod. Background Art
[0002] The juicer is developed on the basis of the conventional juicer. Its main working purpose is to turn the fruit into juice to improve the taste and facilitate drinking. However, the juicer has made a qualitative leap on the basis of the traditional cup blender and juicer. The low-speed spiral extrusion technology of the juicer squeezes out the juice slowly like squeezing a towel, without destroying the cell structure of the fruit, and the nutrition of the fruit is preserved. In addition, the low-speed juice discharge does not generate high heat, and also avoids the problem of heat oxidation of the juice.
[0003] The core components of traditional juicers are the screw assembly and the filter assembly that cooperate with each other. The cutting and extruding ribs on the outer wall of the screw in the screw assembly are all continuous spirals. A material downlink channel is formed between two adjacent cutting and extruding ribs. In actual use, it is found that the continuous spiral cutting and extruding ribs separate the two adjacent material downlink channels, so that the materials entering each material downlink channel cannot be quickly and effectively diverted to the adjacent material downlink channel when the pressure is too high, affecting the efficiency of juicing.

[0007] In the above-mentioned screw for a juicer, the length of the extruded strip is 3-150 mm.
[0008] In the above-mentioned screw for a juicer, the gap between two adjacent extrusion strips located on the same extrusion strip is 1-25 mm.
[0009] In the above-mentioned screw for a juicer, the extrusion strips are composed of a rough extrusion cutting strip located at the upper part of the body and a plurality of fine extrusion cutting strips located at the lower part of the body.
[0010] In the above-mentioned screw for a juicer, the high end surface of the extrusion strip is an inclined surface inclined toward the advancing direction of the material.
[0011] In the above-mentioned screw for a juicer, a pre-crushing head spiraling upward is provided at the upper end of the main body; the upper end of one of the extrusion ribs spirally extends upward along the outer wall of the pre-crushing head and the upper end of the extrusion rib is located on the lower side of the upper end of the pre-crushing head and is in a plane extending outward.
[0012] The vertical projection of the outer contour of the cutting extruded rib (2) located at the upper proximal end is located outside the vertical projection of the outer contour of the lower end of the body (1)
[0013] The latter technical solution of the utility model is implemented as follows: a juicer using the above-mentioned screw includes a main unit, a squeezing cup is detachably connected to the main unit, the squeezing cup is detachably connected to a filter, the screw is arranged in the filter and is linked to the output shaft of the driving device in the main unit.
[0014] In the above juicer, a boss is circumferentially arranged at the lower part of the screw, and the boss is sandwiched between the lower end surface of the filter and the inner bottom of the squeezing cup.
[0015] After adopting the above structure, the utility model designs the original integrated cutting and extruding ribs into segmented cutting and extruding ribs, so that the materials randomly entering each material downward passage can enter the adjacent material downward passage randomly through the gap between two adjacent cutting and extruding ribs when the pressure increases. Through repeated experiments, it is found that this structure can not only prevent the filter components from being damaged due to excessive force, but also improve the efficiency of juice extraction.

[0023] Based on the above concept, the cutting and extruding strips can be arranged in a spiral shape or slightly staggered, as long as the whole is in a spiral shape and can guide the material downward. The segmented cutting and extruding strips can not only make the material go down quickly, but also make the pressure of the material evenly distributed when it goes down. Not only is the juice extraction efficiency high, but the juice extraction components are not easily damaged, especially the filter, which will not be damaged due to excessive pressure.
[0024] Preferably, the length of the cutting extrusion strip 2a is 3-150 mm, depending on the product specifications and requirements. At the same time, the gap between two adjacent cutting extrusion strips 2a on the same cutting extrusion rib 2 is 1-25 mm, depending on the specific requirements and specifications.
[0025] In this embodiment, the cutting and extruding strip 2a is composed of a rough extruding cutting strip 2b located at the upper part of the main body 1 and a plurality of fine extruding cutting strips 2c located at the lower part of the main body 1.
[0026] Preferably, the upper end surface of the cutting and extruding strip 2a is an inclined surface inclined toward the material advancing direction. The inclined surface structure can facilitate the downward guidance of the material, and the tip formed by the inclined surface and the upper end surface is convenient for cutting and crushing fruits and vegetables, so that they can be broken down into smaller pieces more quickly.
[0027] Further preferably, the upper end of the body 1 is provided with a pre-crushing head 3 spirally facing upward; the upper end of one of the cutting and extruding ribs 2 spirally extends upward along the outer wall of the pre-crushing head 3 and the upper end of the cutting and extruding rib 2 is located at the lower side of the upper end of the pre-crushing head 3 and is in a plane shape extending outward. In this embodiment, the rough extrusion cutting strip spirally extends upward along the outer wall of the pre-crushing head 3, and the fine extrusion cutting strip is located at the lower side of the rough extrusion cutting strip. The rough extrusion cutting strip is mainly used to crush and guide downward the large particles that have just entered the extrusion assembly, and the fine extrusion cutting strip is used to further crush and squeeze out the small particles after cutting.
[0028] Further preferably, the vertical projection of the outer contour of the cutting extrusion rib 2 located at the upper proximal end is located outside the vertical projection of the outer contour of the lower end of the body 1. That is, when the central axis of the screw is used as a reference, the distance from the outermost end of the cutting extrusion rib to the central axis of the screw is greater than the distance from the outer wall of the lower end of the body to the central axis of the screw.
[0029] In this structure, the cutting extrusion ribs at the upper proximal end can play a pre-cutting role together with the pre-crushing head, making the pre-cutting effect better. At the same time, the inner diameter of the silo can also be made larger.
[0030] See also Figure 3 and Figure 4 As shown, a juicer using the above-mentioned screw of the utility model comprises a main unit 4, on which a squeezing cup 5 is detachably connected, and the squeezing cup 5 is detachably connected to a filter 6, wherein the screw is arranged in the filter 6 and is connected to the output shaft of the driving device in the main unit 4.
[0031] Preferably, a boss 7 is circumferentially provided at the lower portion of the screw, and the boss 7 is sandwiched between the lower end surface of the filter 6 and the inner bottom of the extrusion cup 5 .
