Description

Technical Field

[0001] The utility model relates to the field of juice extraction equipment, in particular to a juice extraction filter cartridge and a juice extraction device thereof. Background Technique

[0002] In modern life, a healthy diet has become an important goal pursued by people, and drinking fruit and vegetable juices has also become the choice of many families. In the market of juice extraction equipment, it is mainly divided into fast juice extraction equipment and slow juice extraction equipment. Fast juice extraction equipment, also known as a centrifugal juicer, cuts fruits and vegetables into pieces by a high-speed rotating blade and separates the juice from the pulp by centrifugal force. Its working principle is to use the strong centrifugal force generated by high-speed rotation to throw out the juice, and the food residues of fruits and vegetables remain in the filter. The main advantage of this equipment is its high speed, which can complete juice extraction in a few seconds. However, the high-speed rotation of the fast juice extraction equipment also brings some problems. First of all, high-speed rotation generates heat, which may damage some heat-sensitive vitamins and enzymes and affect the nutritional value of the juice. Secondly, high-speed rotation easily causes the juice to oxidize, changing its color and taste.

[0003] Slow juice extraction equipment, also known as a cold press juicer or a spiral juicer, that is, the so-called original juice machine. The original juice machine extracts pure juice from fruits and vegetables by a low-speed extrusion method, retaining the nutritional components and natural flavors of the ingredients. Compared with traditional juicers, the original juice machine generates very little heat during the juice extraction process, and can better maintain the nutritional value and taste of the ingredients. This new type of juice extraction equipment can not only effectively avoid the oxidation problem caused by high-speed rotation, but also minimize the bubbles and impurities in the juice to make the drink purer and healthier.

[0004] Existing juice extractor filters usually separate fruit and vegetable food residues from juice by covering a cylindrical frame with a metal filter. Although this design can effectively filter out the fruit residues, it also brings some problems that cannot be ignored. First, the small mesh holes of the metal filter are easily blocked by fruit and vegetable food residues. During the juicing process, the fibers and particles in the fruit and vegetable food residues will continuously accumulate on the filter. Over time, these small mesh holes will be blocked, resulting in the juice being unable to pass through the filter smoothly, thus affecting the juicing efficiency and effect. Second, when the filter and the screw squeezer work together, the fruit and vegetable raw materials on one side of the filter are easily squeezed upward during the rotation of the screw squeezer. Due to the design characteristics of the screw squeezer, there needs to be a conical feeding space between its upper part and the filter. When the screw squeezer rotates, it will generate a certain pushing force, pushing the raw materials located on the side close to the filter in this conical space upward in the reverse direction along the spiral. This will cause some raw materials to not be fully squeezed and float up and down in the conical space repeatedly, thus reducing the overall juicing efficiency. More seriously, when the raw materials are squeezed upward, the working load of the screw squeezer increases, easily causing the machine to run unstably and even possibly causing mechanical failures. This series of problems not only affect the juicing effect, but also increase the difficulty of cleaning and maintenance for users and reduce the usage experience.

[0005] Therefore, existing slow juicing equipment needs to be further optimized and improved. Summary of the Invention

[0006] The purpose of the present invention is to provide a juicing filter cylinder that is easier to clean by optimizing the filter cylinder design, and at the same time solves the problem of fruit and vegetable food being pushed upward and backward during the juicing process, improving the juicing efficiency and the stability of the equipment.

[0007] To achieve the above purpose, the present invention adopts the following solution: A juicing filter cylinder includes a lower filter frame and an upper filter frame with a through shape at the top and bottom. The upper filter frame is detachably inserted into the lower filter frame to form a filter net body. The gap formed by the mutual insertion of the upper filter frame and the lower filter frame forms a juice outlet gap. On the circumferential inner walls of the upper filter frame and / or the lower filter frame, several first ribs extending downward are respectively arranged at intervals. On the first ribs, a plurality of extrusion inclined surfaces facing obliquely downward are provided. Through the detachable insertion design of the upper filter frame and the lower filter frame, the filter net is easier to clean. The juice outlet gap formed by the gap optimizes the juice outflow path and reduces the possibility of blockage by fruit and vegetable food residues. The setting of the first ribs and the extrusion inclined surfaces on the inner wall effectively guides the fruit and vegetable food residues to be discharged downward, preventing the fruit and vegetable food residues from accumulating on the filter net, and improving the juicing efficiency and the stability of the equipment.

[0008] As a further solution of the present utility model, the upper filter frame includes a first support ring and a second support ring which are arranged at intervals up and down. A plurality of first inserting rods extending downward are sequentially arranged at intervals along the inner circumferential wall of the first support ring. The bottom ends of the first inserting rods extend and are connected to the outer circumferential wall of the second support ring. A first inserting rod groove is formed between adjacent first inserting rods. The lower filter frame includes a third support ring and a fourth support ring which are arranged at intervals up and down. A plurality of second inserting rods extending downward are sequentially arranged at intervals along the inner circumferential wall of the third support ring. The bottom ends of the second inserting rods extend and are connected to the outer circumferential wall of the fourth support ring. A second inserting rod groove is formed between adjacent second inserting rods. When the upper filter frame and the lower filter frame are inserted into each other, the first inserting rods are respectively inserted into the corresponding second inserting rod grooves, and the second inserting rods are respectively inserted into the corresponding first inserting rod grooves. The juice outlet gap is formed between the second inserting rod and the adjacent first inserting rod. The first rib is respectively formed on the inner side wall of the first inserting rod and / or the second inserting rod. The design of the mutual insertion of the first inserting rod and the second inserting rod enables the upper and lower filter frames to be stably connected, and the filter screen is easier to disassemble, assemble and clean. The design of the inserting rod and the inserting slot makes the juice outlet gap more uniform, ensuring the smoothness of the juice outflow. At the same time, by replacing the upper filter frame with inserting rods or slots of different widths, the juice yield of the fruit and vegetable raw materials can be changed according to needs, reducing the problem of blockage of fruit and vegetable food residues.

[0009] As a preferred solution of the present utility model, the inner wall diameter of the first support ring is larger than the outer wall diameter of the second support ring, the inner wall diameter of the third support ring is larger than the inner wall diameter of the fourth support ring, and the outer wall diameter of the second support ring is smaller than the inner wall diameter of the fourth support ring. In this way, the lower filter frame and the upper filter frame can form a cylindrical shape with a small bottom and a large top, which can better cooperate with the screw squeezer to work, ensure that the fruit and vegetable raw materials are fully squeezed, improve the juice extraction efficiency, and this design of the filter frame makes the cleaning more convenient and reduces the residue of fruit and vegetable food residues.

[0010] As a further solution of the present utility model, a fifth support ring is arranged between the third support ring and the fourth support ring. The fifth support ring surrounds the outer wall of the second inserting rod. A positioning bayonet capable of being engaged with a preset position on the inner wall of the juice extraction cup is arranged on the fifth support ring, so that the filter screen body can be stably fixed in the juice extraction cup, preventing it from falling off or shifting due to vibration or movement during the juice extraction process, and ensuring the stability and efficiency of the juice extraction process.

[0011] As a preferred solution of the present utility model, a positioning guide groove is arranged on the inner circumference of the third support ring corresponding to the second inserting rod groove, and a positioning strip capable of being inserted into the positioning guide groove is arranged on the outer wall of the first inserting rod. The design of the positioning guide groove and the positioning strip enables the upper filter frame and the lower filter frame to be accurately aligned when being inserted, avoiding the problem of misalignment during installation, and improving the convenience and accuracy of equipment assembly.

[0012] As a preferred solution of the utility model, a positioning socket is provided at the top position of the fourth support ring corresponding to the second rod slot, and a positioning rod extending downward and capable of being inserted into the corresponding positioning socket is provided on the outer wall of the first rod. This further ensures the accurate alignment of the upper filter frame and the lower filter frame during insertion, making the filter installation more secure, reducing displacement caused by vibration during operation, and improving the reliability and stability of the juice extraction equipment.

[0013] As a preferred solution of the utility model, a second convex rib extending downward is provided at the inner edge of the second plug rod and / or the first plug rod, and the extrusion slopes are sequentially arranged at intervals on the wall surface of each of the first convex ribs facing the center of the filter body, and the slope lengths of each extrusion slope from top to bottom gradually become shorter. The design of the second convex rib and the extrusion slopes arranged thereon closely matches the spiral texture of the spiral extruder, effectively extruding the vegetable and fruit raw materials downward, preventing the problem of the raw materials being pushed upward in the opposite direction, improving the juice extraction efficiency, and ensuring that the juicing process is smoother and more efficient.

[0014] The utility model also provides a scheme of a juice extraction device, including a base with a driving motor installed inside, a juice extraction cup installed on the top of the base, and a crushing cup installed on the top of the juice extraction cup, characterized in that the juice extraction filter cartridge as described above is detachably installed in the juice extraction cup, the motor shaft of the driving motor extends into the center of the filter body, and is connected to a spiral extruder that can rotate in the center of the filter body at the end, the extrusion slope cooperates with the spiral outer wall of the spiral extruder to push the fruit food downward, a feeding port connected to the opening at the top of the filter body is provided at the bottom of the crushing cup, a crushing knife is rotatably provided at the bottom of the inner cavity of the crushing cup, the rotating shaft of the crushing knife is connected to the top of the spiral extruder and rotates synchronously, and a slag discharge channel connected to the bottom opening of the filter body and a juice discharge channel connected to the space between the inner wall of the juice extraction cup and the outer wall of the filter body are provided on the outer wall of the juice extraction cup. The feeding port at the bottom of the crushing cup is connected to the opening at the top of the filter body, so that the fruit and vegetable food crushed materials can smoothly enter the filter body. The shredder is connected to the top of the spiral squeezer and rotates synchronously. Compared with the method of directly putting the cut fruit and vegetable pieces into the filter body, it can reduce the manual operation process, ensure that the fruit and vegetable food materials are fully chopped, and increase the effect and efficiency of juicing.

[0015] As a preferred embodiment of the present utility model, a shaft hole penetrates through the center of the bottom of the juice extraction cup.

First convex ribs are arranged at intervals on the circumferential inner walls of the upper filter frame and / or the lower filter frame, and a plurality of extrusion inclined surfaces facing obliquely downward are provided on these first convex ribs, which are used in cooperation with the screw squeezer. The juice outlet gap and the design of the convex ribs prevent the blockage of vegetable and fruit residues and improve the juice extraction efficiency; the optimized design of the extrusion inclined surfaces closely cooperates with the screw squeezer to ensure that the vegetables and fruits are evenly pushed downward, avoiding being pushed back during the screw extrusion process, thereby improving the juice extraction effect. Using this juice extraction filter cylinder in a juice extraction device further enhances the overall performance of the slow juice extraction device, not only improving the juice extraction efficiency and effect, but also solving the problems of easy blockage and difficult cleaning during the use of traditional juice extraction equipment. The detachable filter cylinder design solves the problems of difficult cleaning of traditional equipment and easy blockage of vegetable and fruit residues.

Thus, features defined with "first" and "second" may explicitly or implicitly include one or more of such features.

[0031] The present utility model will be further described below in conjunction with the accompanying drawings and specific implementation details: As Figures 1 to 3 shown, a juice extraction filter cartridge includes a lower filter frame 10 and an upper filter frame 11 with a through shape at the top and bottom. The upper filter frame 11 is detachably inserted into the lower filter frame 10 to form a filter mesh body 1. The gap formed by the mutual insertion of the upper filter frame 11 and the lower filter frame 10 forms a juice outlet gap 12. A number of first ribs 13 and second ribs 15 extending downward are respectively arranged at intervals on the circumferential inner walls of the upper filter frame 11 and / or the lower filter frame 10. A number of extrusion inclined surfaces 14 facing obliquely downward are successively arranged at intervals on the first ribs 13. The extrusion inclined surfaces 14 face the center of the filter mesh body 1, and the inclined surface lengths of the respective extrusion inclined surfaces 14 from top to bottom gradually become shorter. Since the thread pitch of the spiral thread of the screw extruder gradually narrows from top to bottom, the gradually shortening of the inclined surface lengths of the respective extrusion inclined surfaces 14 can better cooperate with the screw extruder to guide the fruit and vegetable food residues to be discharged downward, prevent the fruit and vegetable food residues from accumulating on the filter mesh, and improve the juice extraction efficiency and the stability of the device. It should be noted that it can be clearly seen from the figure that in this embodiment, the second rib 15 is arranged on one side of the juice outlet gap 12, which can effectively prevent the juice outlet gap 12 from being blocked by fruit and vegetable residues.

[0032] Among them, in this embodiment, the upper filter frame 11 includes a first support ring 111 and a second support ring 112 which are arranged at intervals up and down. A plurality of first insertion rods 113 extending downward are sequentially arranged at intervals along the inner circumferential wall of the first support ring 111. The bottom ends of the first insertion rods 113 extend and are connected to the outer circumferential wall of the second support ring 112. A first insertion rod groove 114 is formed between adjacent first insertion rods 113. The lower filter frame 10 includes a third support ring 101 and a fourth support ring 102 which are arranged at intervals up and down. A plurality of second insertion rods 103 extending downward are sequentially arranged at intervals along the inner circumferential wall of the third support ring 101. The bottom ends of the second insertion rods 103 extend and are connected to the outer circumferential wall of the fourth support ring 102. A second insertion rod groove 104 is formed between adjacent second insertion rods 103. When the upper filter frame 11 and the lower filter frame 10 are inserted into each other, the first insertion rods 113 are respectively inserted into the corresponding second insertion rod grooves 104, and the second insertion rods 103 are respectively inserted into the corresponding first insertion rod grooves 114. The juice outlet gap 12 is formed between the second insertion rod 103 and the adjacent first insertion rod 113. It should be noted that if it is necessary to increase or decrease the juice yield, replace the upper filter frame 11 with different widths of the first insertion rods 113 and insert it into the lower filter frame 10, then the size of the juice outlet gap 12 can be controlled. The first rib 13 is respectively formed on the inner side walls of the first insertion rod 113 and / or the second insertion rod 103. Specifically, the inner wall diameter of the first support ring 111 is larger than the outer wall diameter of the second support ring 112, the inner wall diameter of the third support ring 101 is larger than the inner wall diameter of the fourth support ring 102, and the outer wall diameter of the second support ring 112 is smaller than the inner wall diameter of the fourth support ring 102. In this way, the lower filter frame 10 and the upper filter frame 11 can form a conical cylinder shape with a small bottom and a large top, which can better cooperate with the work of the screw squeezer, ensure that the fruit and vegetable raw materials are fully squeezed, improve the juice extraction efficiency, and this design of the filter frame makes the cleaning more convenient and reduces the residue of fruit and vegetable residues. In order to enable the filter screen body to be stably fixed in the juice extraction cup, prevent falling off or displacement caused by vibration or movement during the juice extraction process, and ensure the stability and efficiency of the juice extraction process. A fifth support ring 105 is provided between the third support ring 101 and the fourth support ring 102. The fifth support ring 105 is coaxial with the third support ring 101 and the fourth support ring 102, and the inner wall of the fifth support ring 105 is respectively connected and fixed to the outer walls of the respective second insertion rods 103.A positioning bayonet 106 capable of being engaged with a preset clamping position on the inner wall of the juice cup 3 is provided on the fifth support ring 105; when the upper filter frame 11 and the lower filter frame 10 are inserted, in order to accurately align and avoid the problem of misalignment during installation, thereby improving the convenience and accuracy of the assembly of the filter screen body 1, a positioning guide groove 107 is provided on the circumference of the third support ring 101 corresponding to the second insertion rod groove 104, a positioning strip 115 capable of being inserted into the positioning guide groove 107 is provided on the outer wall of the first insertion rod 113, a positioning socket 108 is provided at the top position of the fourth support ring 102 corresponding to the second insertion rod groove 104, and a positioning insertion rod 116 extending downward and capable of being inserted into the corresponding positioning socket 108 is provided on the outer wall of the first insertion rod 113. When the entire filter screen body 1 needs to be cleaned, only the upper filter frame 11 needs to be pulled out upward from the lower filter frame 10, and the user can easily and thoroughly clean the entire filter screen body 1. Since there are no extremely fine mesh holes, there is no need to worry about the problem that fruit and vegetable residues cannot be completely removed because they are stuck in the mesh holes.
