Description

Screw, juicing assembly and juicer TECHNICAL FIELD

[0001] The utility model relates to a screw, juicing assembly and juicer. BACKGROUND

[0002] In the existing juicing equipment, the juicing cylinder and the screw are usually composed of multiple parts to achieve effective separation and discharge of juice and dregs. For example, in an existing juicing cylinder design, a separation screw is accommodated inside, which comprises two modules: the first module comprises a hollow first body with a plurality of slits extending along the length around the body. The second module comprises a second body which is detachably coupled to the first body, and the second body has ribs formed thereon which are inserted into the slits of the first body. TECHNICAL PROBLEM

[0003] When the second module is coupled to 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 pressed between the separation screw and the juicing cylinder into juice and dregs, the juice flows into the interior of the separation screw through the gap between the ribs and the slits, and then is discharged through the juice discharge groove, while the dregs are discharged through the dreg discharge groove.

[0004] Although this prior art can achieve the separation of juice and dregs, its design and manufacturing process is complex, for example, the screw requires precise alignment and assembly of multiple parts, which increases the manufacturing cost and assembly difficulty. TECHNICAL SOLUTION

[0005] The first purpose of the utility model is to provide a screw which simplifies manufacturing and assembly and reduces cost.

[0006] The first purpose is achieved by a screw comprising a screw body, the outer wall of the screw body is provided with threads; the inner cavity of the screw body is provided with a juice receiving cavity; the outer wall of the screw body is spaced apart with juice inlet ports which communicate with the juice receiving cavity. During the juicing process, the juice enters the juice receiving cavity in the inner cavity of the screw body through the juice inlet ports on the outer wall of the screw body. These juice inlet ports are designed to be small and have a dreg separation function, which can effectively filter dregs, making the juice more pure, avoiding the mixing of juice and dregs in traditional juicers, and improving the quality of the juice, so the screw body has a filtering function.

[0007] During the juicing process, the thread design on the outer wall of the screw body also helps to enhance the pressing effect and ensure the continuity and stability of the juice discharge, so the screw body has a pressing function.

[0008] By directly collecting and filtering the juice through the juice receiving cavity inside the screw body, the structure design of the juicer is simplified (without the need for additional filter screen), the complex process of separating the juice and the pomace after they fall to the bottom of the juicing cavity is reduced, the number of parts that need to be cleaned is reduced, and the cleaning is simpler and more efficient.

[0009] The first purpose of the utility model can also be solved by the following technical measures:

[0010] Further, the inner cavity of the screw body is a hollow inner cavity, and the hollow inner cavity forms the juice receiving cavity.

[0011] The hollow inner cavity design of the screw body forms the juice receiving cavity, so that the juice can be directly collected into the juice receiving cavity during the pressing process. Compared with the traditional design, this internal channel design reduces the path and resistance of the juice flow, improving the collection efficiency of the juice. The hollow inner cavity design allows the juice to collect in the inner cavity of the screw body and enter the juice receiving cavity through the juice inlet. Since the juice inlet is small, it has a residue separation function, which can effectively filter out pomace, making the juice more pure and improving the quality of the juice. By designing the juice receiving cavity in the hollow inner cavity of the screw body, the overall structure design of the juicer is simplified, and the use of external pipelines and components is reduced. This integrated design reduces manufacturing and maintenance costs and improves the reliability of the equipment. The integrated design of the hollow inner cavity and the juice receiving cavity makes juice collection more concentrated and convenient. When cleaning the juicer, the user only needs to clean the inner cavity of the screw body and the juice inlet, reducing the difficulty and time of cleaning and improving the convenience of use. The design of the hollow inner cavity not only reduces the weight of the screw body, but also reduces the inertial force of the equipment when running at high speed, making the juicer run more smoothly, reducing vibration and noise, and improving the stability of the equipment and the user experience.

[0012] Further, the bottom of the screw body is provided with a juice outlet corresponding to the position of the juice receiving cavity.

[0013] The juice outlet design at the bottom of the screw body directly discharges the juice in the juice receiving cavity, greatly shortening the path and time of the juice from pressing to discharging, improving the juice discharge efficiency, and ensuring that the juice can be quickly collected to prevent juice oxidation due to prolonged juicing time. The juice outlet design at the bottom of the screw body makes the juice discharge more direct and complete, reducing the residue and accumulation of juice inside the equipment, facilitating user cleaning and maintenance, and improving the convenience of use. The bottom juice outlet design allows the juice to flow 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.

[0014] Further, the juice inlet is a vertical or inclined opening.

[0015] Further, the inner wall of the screw body is provided with a V-shaped groove, the tip of the V-shaped groove is communicated with the juice inlet, and the opening of the V-shaped groove is directed to and communicated with the juice receiving cavity.

[0016] The opening of the V-shaped groove in the inner wall of the screw body is directed to and communicated with the juice receiving cavity, so that the fruit juice can smoothly enter the juice receiving cavity. The vertical or inclined juice inlet and the V-shaped groove are combined, so that the fruit juice can be quickly extracted and enter the juice receiving cavity.

[0017] Further, the width of the juice inlet is smaller than the opening width of the V-shaped groove.

[0018] 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, effectively reducing the influence of the pomace on the quality of the fruit juice, and improving the taste and clarity of the fruit juice.

[0019] The second purpose of the utility model is to provide a juicing assembly with a screw body, a pressing plate and a cutting knife integrated design, which is more convenient to install and disassemble.

[0020] The above purpose is achieved by a juicing assembly, which comprises a screw body, a pressing plate, a cutting knife and a transmission shaft, the outer wall of the screw body is provided with a screw thread, the inner cavity of the screw body is provided with a juice receiving cavity, the outer wall of the screw body is spaced apart from a juice inlet which is communicated with the juice receiving cavity, the transmission shaft is arranged in the inner cavity of the screw body, the transmission shaft and the screw body are integrally formed, the head of the transmission shaft protrudes outward through the screw body, the cutting knife is arranged on the pressing plate in a rotating manner, the pressing plate is connected with the screw body and located above the screw body, the head of the transmission shaft is connected with the cutting knife through the pressing plate, and the transmission shaft rotates to drive the screw body and the cutting knife to rotate synchronously.

[0021] In 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, improving the juice yield of the juice, and 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 extraction, so the screw body has a squeezing function. In the juicing process, the juice enters the juice collection 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 fruit residue, making the juice more pure, avoiding the mixing of fruit juice and fruit residue in traditional juicers, and improving the quality of the juice, so the screw body has a filtering function. The juice is directly collected and filtered through the juice collection cavity in the inner cavity of the screw body, simplifying the structural design of the juicer, reducing the complex process of separating the juice and fruit residue after falling to the bottom of the juicing chamber, reducing the number of parts that need to be cleaned, and making cleaning easier and more efficient. The cutting knife rotates synchronously with the screw body to preliminarily cut the food entering the screw body. This can effectively shred large food materials, reducing the workload of the screw body and improving the efficiency of the entire squeezing process. 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 and ensuring the stability of the food material during the squeezing process, improving the juice yield and juice quality. Since 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, the power device drives the screw body and the cutting knife to rotate synchronously through the power component and the transmission shaft, ensuring that the food material can be fully cut and broken before entering the screw body, reducing the jamming phenomenon, and improving the stability and continuity of the juicer.

[0022] The integrated design of the screw body, cutting knife and pressing plate allows the user to easily disassemble and clean the entire juicing assembly after use, reducing the cleaning difficulties caused by the separation of multiple components in traditional juicers. At the same time, the assembly process is also more simple, and the user can complete the assembly and disassembly of the equipment without complicated operations, improving the convenience of use.

[0023] The integrated design reduces the connection and wear between components, reduces the risk of equipment failure caused by loose or damaged parts, enhances the overall safety and durability of the juicer, and prolongs the service life of the equipment. By placing the transmission shaft in the inner cavity of the screw body and integrating the transmission shaft and the screw body, the internal structure design of the juicer is simplified, the number and complexity of components are reduced, and the manufacturing and maintenance costs are reduced.

[0024] The integrated design and optimized synchronous rotation mechanism make the juicer run more smoothly during operation, reduce mechanical noise, provide a quieter use environment, and improve the user's experience.

[0027] The bushing wear-resistant part is placed in the insertion hole and has excellent wear resistance, which can effectively reduce the friction and wear between the transmission shaft and the pressing plate, prolong the service life of the juicer and improve the reliability of the equipment.

[0028] The head of the transmission shaft is tightly matched with the bushing wear-resistant part through the connecting cavity, the bolt is locked through the cutting tool and the bushing wear-resistant part, and the stable connection between the cutting tool, the pressing plate and the screw body is ensured.

[0029] The design of the upper connecting snap ring and the upper connecting snap cavity enables the cutting tool to be quickly installed on the bushing wear-resistant part, the head of the transmission shaft is locked through the bolt, and quick assembly and disassembly are realized. The stable connection and wear-resistant design ensures that the cutting tool can effectively perform preliminary cutting processing on food materials during rotation, improves the pressing efficiency of food materials entering the screw body, and ensures high juice yield. The application of the wear-resistant part reduces the wear between the transmission shaft and other parts, reduces the jamming phenomenon and equipment failure rate caused by wear, and improves the overall performance and user experience of the juicer. The head of the transmission shaft is locked through the bolt, which ensures the safe operation of the cutting tool, the pressing plate and the screw body under high load working conditions, avoids safety hazards caused by loose connection, and protects the safety of users. The design of the connecting snap ring and the upper connecting snap cavity ensures the stable connection of the cutting tool and the bushing wear-resistant part, avoids loosening or deviation of the cutting tool during work, and guarantees the efficient cutting performance of the cutting tool and the overall stability of the juicer.

The cover prevents foreign matter from entering the bolt hole, improving the safety of the equipment. The cover covers the first bolt hole, preventing debris, fruit juice and other impurities from entering the bolt hole, preventing the bolt hole from being contaminated and corroded, and prolonging the service life of the bolt and the equipment. At the same time, the cover can also prevent water from entering the bolt hole during cleaning, reducing rust and wear of the bolt, and maintaining the cleanliness and durability of the equipment. The cover not only has functionality, but also makes the appearance of the equipment more neat and beautiful. The design of the cover hides the bolts and the connecting holes, making the overall appearance of the juicer more simple and streamlined, improving the appearance of the product and enhancing the visual experience of the user. By passing the bolt through the first bolt hole of the cutting tool, the second bolt hole of the shaft sleeve wear-resistant part, and locking in the third bolt hole of the screw body, a stable connection structure is formed. The arrangement of the cover further protects the fastening state of the bolt, prevents loosening or displacement caused by external factors, and ensures the stability and reliability of the juicer under high load working conditions. The design of the cover makes it more convenient for users to clean and maintain the juicer. The closed bolt hole avoids the accumulation of dirt and fruit pulp, reducing the difficulty of cleaning, and users can easily maintain the cleanliness and hygiene of the equipment.

[0032] Further, the inner cavity of the screw body is a hollow inner cavity, and the hollow inner cavity forms the juice receiving cavity.

[0033] 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 pressing process. Compared with the traditional design, this internal channel design reduces the path and resistance of the juice flow, improving the collection efficiency of the juice. The hollow inner cavity design allows the juice to collect in the inner cavity of the screw body and enter the juice receiving cavity through the juice inlet. Since the juice inlet is small, it has a residue separation function, which can effectively filter out the fruit pulp, making the juice more pure and improving the quality of the juice.

[0073] By designing the juice receiving cavity in the hollow inner cavity of the screw body, the overall structure design of the juicer is simplified, and the use of external pipelines and components is reduced. This integrated design reduces manufacturing and maintenance costs and improves the reliability of the equipment. The integrated design of the hollow inner cavity and the juice receiving cavity makes juice collection more centralized and convenient. When cleaning the juicer, users only need to clean the inner cavity of the screw body and the juice inlet, reducing the difficulty and time of cleaning and improving the convenience of use. The design of the hollow inner cavity not only reduces the weight of the screw body, but also reduces the inertial force of the equipment during high-speed operation, making the juicer run more smoothly, reducing vibration and noise, and improving the stability of the equipment and the user's experience.

[0074] Further, the bottom of the screw body has a juice outlet corresponding to the position of the juice receiving cavity.

[0075] The juice outlet at the bottom of the screw body directly discharges the juice in the juice receiving cavity, greatly shortening the path and time of juice from being squeezed to being discharged, improving the juice discharge efficiency, ensuring that the juice can be quickly collected, and preventing juice oxidation caused by long juicing time. The juice outlet design at the bottom of the screw body makes the juice discharge more direct and complete, reduces the residue and accumulation of juice inside the equipment, facilitates user cleaning and maintenance, and improves the convenience of use. The bottom juice outlet design allows the juice to be smoothly discharged, reducing the risk of juice accumulation and blockage in the screw body cavity, ensuring long-term stable operation of the juicer, and reducing the failure rate.

[0076] Further, the juice inlet is a vertical opening, the inner wall of the screw body is provided with a V-shaped groove, the tip of the V-shaped groove communicates with the juice inlet, and the opening of the V-shaped groove faces and communicates with the juice receiving cavity. The width of the juice inlet is less than the opening width of the V-shaped groove.

[0077] The V-shaped groove opening of the inner wall of the screw body faces and communicates with the juice receiving cavity, so that the juice can smoothly enter the juice receiving cavity. Since the width of the juice inlet is less than the opening width of the V-shaped groove, the pomace cannot enter the juice receiving cavity, effectively reducing the influence of pomace on the quality of the juice, and improving the taste and clarity of the juice. The combination of the vertical opening of the juice inlet and the V-shaped groove design allows the juice to be quickly extracted and enter the juice receiving cavity. This precise food material guiding and separating design improves the extraction efficiency and juice yield of the juice, ensuring higher juice yield.

[0078] The vertical opening of the juice inlet and the V-shaped groove design simplify the cleaning process. The pomace is mainly left in the V-shaped groove, which can be easily removed during cleaning, reducing the difficulty and time of cleaning, and improving the convenience of use. Advantages

[0079] (1) In the juicing process of this utility model, the juice enters the receiving chamber of 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 pulp separation function, which can effectively filter the pulp, making the juice purer and avoiding the mixing of juice and pulp in traditional juicers, thus improving the quality of the juice. This utility model directly collects and filters juice through the receiving chamber inside the screw body, which simplifies the structural design of the juicer, reduces the complex process of juice and pulp 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, and makes cleaning simpler and more efficient. In this utility model, the juice outlet design at the bottom of the screw body directly discharges the juice in the receiving chamber, which greatly shortens the path and time of the juice from pressing to discharge, improves the juice discharge efficiency, and ensures that the juice can be collected quickly. In this utility model, the vertical or oblique opening and V-shaped groove design of the juice inlet simplifies the cleaning process. The pulp mainly remains in the V-shaped groove, which can be more easily removed during cleaning, reducing the difficulty and time of cleaning and improving the convenience of use. In this invention, because the width of the juice inlet is smaller than the opening width of the V-shaped groove, fruit pulp cannot enter the juice receiving chamber, effectively reducing the impact of fruit pulp on the quality of the juice and improving the taste and clarity of the juice.

[0080] (2) In this invention, the cutting blade rotates synchronously with the screw body, performing preliminary cutting on the food entering the screw body. This effectively shreds large pieces of food, reducing the workload of the screw body and improving the efficiency of the entire pressing process. In this invention, the pressure plate is positioned above the screw body to prevent the screw from moving upwards during the juicing process, thereby fixing the screw position, ensuring the stability of the food during the pressing process, and improving the juice yield and juice quality. In this invention, the motor drives the screw body and the cutting blade to rotate synchronously through the rotating shaft and transmission shaft, ensuring that the food can be fully cut and crushed before entering the screw body, reducing jamming and improving the stability and continuity of the juicer. In this invention, the integrated design of the screw body, cutting blade, and pressure plate allows users to easily disassemble and clean the machine after use, reducing the cleaning difficulties 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 complicated operations, improving the convenience of use. This invention simplifies the internal structure design of the juicer by placing the drive shaft inside the screw body and integrally molding the drive shaft and screw body. This reduces the number and complexity of parts, thereby lowering manufacturing and maintenance costs. Furthermore, the integrated design and optimized synchronous rotation mechanism of this invention result in smoother operation of the juicer, reduced mechanical noise, a quieter operating environment, and an enhanced user experience.

[0081] (3) In this utility model, the main unit, juicing components, feeding chamber, and juicing cylinder are all designed to be detachable, allowing users to easily disassemble each component for cleaning, effectively avoiding fruit residue residue and improving the hygiene of the juicer and the user experience. In this utility model, during the juicing process, the juice enters the receiving chamber 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-separating function, which can effectively filter fruit residue, making the juice purer and avoiding the mixing of juice and pulp in traditional juicers, thus improving the quality of the juice. In this utility model, the juice is directly collected and filtered through the receiving chamber inside the screw body, simplifying the structural design of the juicer, reducing the complex process of juice and pulp falling to the bottom of the juicing chamber and then being separated, and reducing the failure rate and maintenance cost of the machine. In this utility model, the power unit drives the screw body to rotate, so that the fruits and vegetables are fully pressed in the pressing area, increasing the juice yield. The threaded design on the outer wall of the screw body also helps to enhance the pressing effect and ensure the continuity and stability of the juice output. This invention features an installation cavity in the main unit corresponding to the juicing cylinder, with a first and second notch on the side wall of the main unit to ensure accurate positioning and secure installation of the juicing cylinder. The slag discharge port and juice discharge port of the juicing cylinder are respectively secured to the first and second notches, enabling quick installation and disassembly. Users can complete assembly and cleaning without complex operations. The ribs on the inner wall of the feeding chamber effectively prevent food from rotating within the chamber, maintaining a stable position during screw pressing and preventing reduced pressing efficiency due to food rotation. This stable food position ensures thorough pressing, increasing juice yield. Furthermore, the ribs not only prevent food rotation but also provide initial crushing during feeding. The partially crushed food before entering the screw helps the screw press more efficiently, further improving the juice yield and quality. The slot and locking block design allows for easy assembly and disassembly of the feeding chamber and juicing cylinder. Users simply insert the card block into the slot to complete assembly, requiring no additional tools or complicated steps, thus improving the ease of use and operational efficiency of the equipment. In this invention, the cutting blade rotates synchronously with the screw body, performing preliminary cutting of the food entering the screw body. This effectively shreds large pieces of food, reducing the workload on the screw body and improving the efficiency of the entire pressing process. In this invention, the pressure plate is positioned above the screw body to prevent the screw from moving upwards during juicing, thereby fixing the screw position and ensuring the stability of the food during pressing, improving juice yield and juice quality. In this invention, the integrated design of the screw body, cutting blade, and pressure plate allows for easy disassembly and cleaning after use, reducing the cleaning difficulties caused by the separation of multiple parts in traditional juicers. At the same time, the assembly process is also simpler; users can complete the assembly and disassembly of the equipment without complicated operations, improving ease of use.
