Description

Technical Field

[0001] The utility model relates to a screw rod, a juice extracting component and a juice extractor. 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 first purpose of the utility model is to provide a screw rod which simplifies manufacturing and assembly and reduces costs.

[0008] The second object of the utility model is to provide a juice extracting assembly with an integrated design of a screw body, a pressing plate and a cutting knife, which is easier to install and disassemble.

[0009] The third object of the utility model is to provide an efficient, convenient and durable juicer.

[0010] The first purpose of the utility model is achieved in this way:

[0011] A screw rod comprises a screw rod body, wherein the outer wall of the screw rod body is provided with threads;

[0012] The inner cavity of the screw body is provided with a juice receiving cavity;

[0013] The outer wall of the screw body is spaced apart with juice inlet holes connected to the juice receiving cavity;

[0014] A conical groove is formed on the inner wall of the screw body corresponding to the position of the juice inlet hole, the tip end of the conical groove is connected to the juice inlet hole, and the opening of the conical groove faces and is connected to the juice receiving cavity.

[0015] The screw body adopts an integrated molding design, which reduces the number of parts and assembly steps, simplifies the manufacturing process, improves production efficiency and reduces manufacturing costs.

[0016] The outer wall of the screw body is provided with threads, which drive the fruits or vegetables into the pressing area through rotation, thereby increasing the pressing force and improving the recovery rate of the juice.

[0017] The conical groove design arranged on the inner wall of the screw body enables the juice to smoothly enter the juice receiving chamber through the juice inlet hole, reducing the flow resistance and further improving the juice extraction efficiency.

[0018] 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.

[0019] During the juicing process, the juice enters the juice receiving chamber in the inner cavity of the screw body through the juice inlet holes on the outer wall of the screw body. These juice inlet holes are designed to be small and have the function of separating residues, which can effectively filter the residues, making the juice purer, avoiding the mixing of juice and residues in traditional juicers, and improving the quality of the juice. Therefore, the screw body has a filtering function.

[0020] The juice is directly collected and filtered through the juice collecting chamber inside the screw body, which simplifies the structural design of the juicer, reduces the complicated process of juice and pomace falling to the bottom of the juicing chamber at the same time and then being separated, and reduces the failure rate and maintenance cost of the machine.

[0021] The first purpose of the utility model can also be solved by the following technical measures:

[0022] Furthermore, the inner cavity of the screw body is a hollow inner cavity, and the hollow inner cavity forms the juice receiving cavity.

[0023] 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.

[0024] The hollow inner cavity design allows the juice to gather in the inner cavity of the screw body and enter the juice receiving cavity through the juice inlet hole. Since the juice inlet hole 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.

[0025] 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.

[0026] The integrated design of the hollow inner cavity and the juice receiving 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 hole, which reduces the difficulty and time of cleaning and improves the convenience of use.

[0027] 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.

[0028] Furthermore, a juice outlet is provided at the bottom of the screw body corresponding to the position of the juice receiving chamber.

[0029] 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 due to long juicing time.

[0030] 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.

[0031] 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.

[0032] Furthermore, a juice inlet channel is formed on the side wall of the screw body, one end of the juice inlet channel is connected to the juice inlet hole, and the other end of the juice inlet channel is connected to the tip end of the tapered groove.

[0033] One end of the juice inlet channel is connected to the juice inlet hole, and the other end is connected to the tip end of the conical groove, so that the process of juice flowing from the juice inlet hole into the juice receiving cavity is smoother, the flow efficiency of the juice is improved, and the possibility of blockage is reduced.

[0034] The combination of the conical groove design and the juice inlet channel ensures that the juice is guided into the juice receiving chamber faster and more evenly during the juicing process, optimizes the separation of juice and pomace, and improves the juice extraction rate.

[0035] The connected juice inlet channel and conical groove design effectively reduce the residue in the screw body, ensuring that more juice is separated and collected smoothly, thus improving the juicing efficiency.

[0036] The design of the juice inlet channel prevents the juice from stagnating in a complex path during its flow, reduces dead corners that need to be cleaned during cleaning, simplifies the cleaning process, and improves the hygiene level of the equipment.

[0037] Through the scientific and reasonable design of juice inlet channel and tapered groove, the structural strength of the screw body is maintained while ensuring efficient juice inlet, and the durability and service life of the screw will not be weakened due to redundant openings.

[0038] The optimized juice inlet channel design makes the juicer operate more smoothly and provides a more user-friendly experience. The juice flows more smoothly, and users can more intuitively feel the improvement in juicing effect.

[0039] The coordinated design of the juice inlet channel and the conical groove makes the juice separation process more efficient and reduces the energy loss during the rotation of the screw, thereby reducing the overall energy consumption of the equipment and improving energy utilization.

[0040] In summary, the reasonable layout of the juice inlet channel and the conical groove significantly improves the working efficiency and user experience of the juicer, while ensuring the easy cleaning and structural stability of the equipment.

[0041] The second purpose of the utility model is achieved in this way:

[0042] A juice extraction assembly comprises a pressing plate, a cutting blade and a transmission shaft, wherein the transmission shaft is disposed in an inner cavity of a screw body, the transmission shaft and the screw body are integrally formed, and a head of the transmission shaft passes through the screw body and extends outward;

[0043] The cutting blade is rotatably arranged on a pressing plate, and the pressing plate is connected to the screw body and is located above the screw body;

[0044] The head of the transmission shaft passes through the pressure plate and is connected to the cutting blade, and the rotation of the transmission shaft drives the screw body and the cutting blade to rotate synchronously.

[0045] The cutter rotates synchronously with the screw body to perform preliminary cutting on the food entering the screw body. This can effectively chop up large pieces of food, reduce the workload of the screw body, and improve the efficiency of the entire pressing process.

[0046] The pressing plate is arranged above the screw body to prevent the screw from moving upwards during the juicing process, thereby fixing the position of the screw, ensuring the stability of the food during the squeezing process, and improving the juice yield and juice quality.

[0047] Since the pressure plate is arranged above the screw body, it prevents the screw from moving upwards during the juicing process, thereby fixing the screw position.

[0048] The power device drives the screw body and the cutting blade to rotate synchronously through the power components and the transmission shaft, ensuring that the food can be fully cut and crushed before entering the screw body, reducing the jamming phenomenon and improving the stability and continuity of the juicer.

[0049] The integrated design of the screw body, cutting blade and pressing plate allows users to easily disassemble and clean the entire juice extraction assembly after use, reducing the difficulty of cleaning caused by the separation of multiple parts in traditional juicers. At the same time, the assembly process is also simpler, and users can complete the assembly and disassembly of the equipment without tedious operations, which improves the convenience of use.

[0050] The one-piece design reduces the connection and wear between components, reduces the risk of equipment failure due to loose or damaged parts, enhances the overall safety and durability of the juicer, and extends the service life of the equipment.

[0051] By placing the transmission shaft in the inner cavity of the screw body and forming the transmission shaft and the screw body in one piece, the internal structure design of the juicer is simplified, the number and complexity of parts are reduced, and thus the manufacturing and maintenance costs are reduced.

[0052] The integrated design and optimization of the synchronous rotation mechanism make the juicer run more smoothly during operation, reduce mechanical noise, provide a quieter operating environment, and enhance the user experience.

[0056] The head of the transmission shaft passes through the pressure plate and is connected to the cutting blade, and the rotation of the transmission shaft drives the screw body and the cutting blade to rotate synchronously;

[0057] The juice extraction cylinder is provided with a juice extraction chamber for accommodating a juice extraction component, the juice extraction component is placed in the juice extraction chamber, and a pressing area is formed between the outer wall of the screw body and the inner wall of the juice extraction chamber;

[0058] The juicer is provided with a slag discharge port, and the slag discharge port is connected to the pressing area;

[0059] The juice extractor is arranged at a juice outlet, and the juice outlet is connected to the juice receiving chamber.

[0060] The juice extractor is seated on the main machine, and the power component of the power device passes through the juice extractor and is connected to the screw body, and the power device drives the screw body to rotate;

[0061] The feed bin is arranged on the juice extraction cylinder and is located above the screw body, and the feed bin is communicated with the juice extraction chamber.

[0062] During the juicing process, the power device drives the screw body to rotate, so that the fruits and vegetables are fully squeezed in the squeezing area, thereby improving the juice yield. The threaded design of the outer wall of the screw body also helps to enhance the squeezing effect and ensure the continuity and stability of the juice output. Therefore, the screw body has a squeezing function.

[0063] During the juicing process, the juice enters the juice receiving chamber in the inner cavity of the screw body through the juice inlet holes on the outer wall of the screw body. These juice inlet holes are designed to be small and have the function of separating residues, which can effectively filter the residues, making the juice purer, avoiding the mixing of juice and residues in traditional juicers, and improving the quality of the juice. Therefore, the screw body has a filtering function.
