Description

Technical Field

[0001] The utility model relates to a screw rod. Background Art

[0002] In existing juice extraction equipment, the juice extraction cylinder and the screw are usually composed of multiple components to achieve effective separation and discharge of juice and pomace. For example, in an existing juice extraction cylinder design, a separation screw is contained inside, and the screw includes the following two modules:

[0003] The first module comprises a hollow first main body, and a plurality of slits are extended along the length direction around the main body.

[0004] The second module comprises a second body which can be detachably combined with the first body, and ribs are formed on the second body, and the ribs are inserted into the slits of the first body.

[0005] When the second module is combined with the first module, a separation screw for juicing is formed. Due to the structural reasons of the split design of the screw body, the strength of the screw body is weak. The juicing object is squeezed into juice and dregs between the separation screw and the juicing barrel. The juice flows into the interior of the separation screw through the gap between the ribs and the slits, and then discharged through the juice discharge groove, while the dregs are discharged through the dregs discharge groove.

[0006] Although this prior art can achieve the separation of juice and pomace, its design and manufacturing process are complicated. For example, the screw requires precise alignment and assembly of multiple parts, which increases the manufacturing cost and assembly difficulty. Utility Model Content

[0007] The utility model aims to provide a screw rod which simplifies manufacturing and assembly and reduces costs.

[0008] The purpose of the utility model is achieved in this way:

[0009] A screw rod comprises a screw rod body, wherein the outer wall of the screw rod body is provided with threads;

[0010] The inner cavity of the screw body is provided with a juice receiving cavity;

[0011] The outer wall of the screw body is spaced apart with a juice inlet connected to the juice receiving cavity.

[0012] During the juicing process, the juice enters the juice receiving chamber in the inner cavity of the screw body through the juice inlet on the outer wall of the screw body. These juice inlets are designed to be small and have a slag separation function, which can effectively filter the pomace, making the juice purer, avoiding the mixing of juice and pomace in traditional juicers, and improving the quality of the juice. Therefore, the screw body has a filtering function.

[0013] During the juicing process, the thread design of the outer wall of the screw body also helps to enhance the squeezing effect, ensuring the continuity and stability of the juice output, so the screw body has a squeezing function.

[0014] The juice is directly collected and filtered through the juice collecting chamber inside the screw body, which simplifies the structural design of the juicer (no additional filter is required), reduces the complicated process of juice and pomace falling to the bottom of the juicing chamber at the same time and then being separated, reduces the number of parts that need to be cleaned in the juicer, and makes cleaning simpler and more efficient.

[0015] The purpose of the utility model can also be solved by the following technical measures:

[0016] Furthermore, the inner cavity of the screw body is a hollow inner cavity, and the hollow inner cavity forms the juice receiving cavity.

[0017] The hollow inner cavity design of the screw body forms a juice receiving cavity, so that the juice can directly enter the juice receiving cavity for collection during the squeezing process. Compared with the traditional design, this internal channel design reduces the path and resistance of the juice flow and improves the efficiency of juice collection.

[0018] The hollow inner cavity design allows the juice to gather in the inner cavity of the screw body and enter the juice receiving chamber through the juice inlet. Since the juice inlet is small and has the function of separating residues, it can effectively filter out the residues, making the juice purer and improving the quality of the juice.

[0019] By designing the juice receiving chamber in the hollow inner cavity of the screw body, the overall structural design of the juicer is simplified and the use of external pipes and components is reduced. This integrated design reduces manufacturing and maintenance costs and improves the reliability of the equipment.

[0020] The integrated design of the hollow inner cavity and the juice collecting cavity makes juice collection more centralized and simple. When cleaning the juicer, users only need to clean the inner cavity of the screw body and the juice inlet, which reduces the difficulty and time of cleaning and improves the convenience of use.

[0021] The hollow inner cavity design not only reduces the weight of the screw body, but also reduces the inertia force of the equipment when it runs at high speed, making the juicer run more smoothly, reducing vibration and noise, and improving the stability of the equipment and the user experience.

[0022] Furthermore, a juice outlet is provided at the bottom of the screw body corresponding to the position of the juice receiving chamber.

[0023] The juice outlet design at the bottom of the screw body directly discharges the juice in the juice receiving chamber, greatly shortening the path and time from squeezing to discharge of the juice, improving the juice discharge efficiency, ensuring that the juice can be collected quickly, and preventing juice oxidation caused by long juicing time.

[0024] The juice outlet design at the bottom of the screw body makes the juice discharge more direct and thorough, reduces the residue and accumulation of juice inside the equipment, facilitates users to clean and maintain, and improves ease of use.

[0025] The bottom juice outlet design allows the juice to be discharged smoothly, reducing the risk of juice accumulation and blockage in the inner cavity of the screw body, ensuring the long-term stable operation of the juicer and reducing the failure rate.

[0026] Furthermore, the juice inlet is a vertical or oblique opening.

[0027] Furthermore, a V-shaped groove is formed on the inner wall of the screw body, the tip of the V-shaped groove is connected to the juice inlet, and the opening of the V-shaped groove faces and is connected to the juice receiving cavity.

[0028] The V-shaped groove opening on the inner wall of the screw body faces toward and is connected to the juice receiving chamber, so that the juice can smoothly enter the juice receiving chamber.

[0029] The combination of the vertical or oblique opening of the juice inlet and the V-shaped groove design allows the juice to be quickly extracted and enter the juice receiving chamber. This precise food guide and separation design improves the juice extraction efficiency and juice yield, ensuring a higher juice yield.

[0030] The vertical or oblique opening and V-shaped groove design of the juice inlet simplifies the cleaning process. The pomace mainly stays in the V-shaped groove, which makes it easier to remove the pomace during cleaning, reducing the difficulty and time of cleaning and improving the convenience of use.

[0031] Furthermore, the width of the juice inlet is smaller than the opening width of the V-shaped groove.

[0032] Since the width of the juice inlet is smaller than the opening width of the V-shaped groove, the pomace cannot enter the juice receiving cavity, which effectively reduces the impact of the pomace on the quality of the juice and improves the taste and clarity of the juice.

[0033] The beneficial effects of the utility model are as follows:

[0034] In the utility model, during the juicing process, the juice enters the juice receiving cavity in the inner cavity of the screw body through the juice inlet on the outer wall of the screw body. These juice inlets are designed to be small and have a residue separation function, which can effectively filter the pomace, making the juice purer, avoiding the mixing of juice and pomace in traditional juicers, and improving the quality of the juice.

[0035] The utility model directly collects and filters juice through the juice receiving cavity inside the screw body, simplifies the structural design of the juicer, reduces the complicated process of juice and pomace falling to the bottom of the juice extraction cavity at the same time and then being separated, reduces the number of parts of the juicer that need to be cleaned, and makes cleaning simpler and more efficient.

[0036] The utility model adopts a juice outlet design at the bottom of the screw body to directly discharge the juice in the juice receiving chamber, which greatly shortens the path and time from squeezing to discharging the juice, improves the juice discharge efficiency, and ensures that the juice can be quickly collected.

[0037] The utility model simplifies the cleaning process by designing the vertical or oblique opening and the V-shaped groove of the juice inlet. The pomace mainly stays in the V-shaped groove, and the pomace can be removed more easily during cleaning, thereby reducing the difficulty and time of cleaning and improving the convenience of use.

[0038] In the utility model, since the width of the juice inlet is smaller than the opening width of the V-shaped groove, the pomace cannot enter the juice receiving cavity, thereby effectively reducing the influence of the pomace on the quality of the juice and improving the taste and clarity of the juice.
