Description

Technical Field

[0001] The present invention relates to a juicer, and more particularly to a juicer as follows: in order to cut materials, the juicer allows a crushing clamp that cooperates with a screw to enter the inside of a moving path for installing and removing the screw inside a shell to strengthen the mutual cooperation with the screw, thereby being able to effectively cut larger materials. Background Art

[0002] For health reasons, there is an increasing trend of preparing and consuming green juice or fruit juice directly at home. To this end, many devices that can easily prepare juice using vegetables or fruits at home have been disclosed.

[0003] In the past, juicers put the raw materials into the inlet, crush them with high-speed rotating blades, and make juice by centrifugal separation. However, the high-speed crushing process of such juicers may destroy the original taste and nutritional components of the materials, and it is difficult to make green juice with stems or leaves of vegetables, and it is difficult to make juice with high-viscosity fruits such as kiwi or strawberry, and it is impossible to make soy milk with soybeans.

[0004] In order to solve the above-mentioned problems, the technical solution disclosed in Korean Patent No. 10-0793852 is a method of squeezing and crushing materials between a mesh cylinder and a low-speed rotating screw, which has the following effects: that is, soybeans are made into soy milk by the principle of grinding and squeezing with a grindstone, and fruits with high viscosity such as tomatoes, kiwis, strawberries, etc. are made into juice by grinding and squeezing on a steel plate, thereby solving the problems of the previous juicers mentioned above.

[0005] However, in this case, due to the size of the screw and the size of the input port, it is troublesome to cut the material into small pieces before inputting the material into the input port. The size of the input port is made according to the size of the screw to input the material of appropriate size.

[0006] To this end, in Korean Patent No. 10-1270140, the size of the input port is increased, and the larger material is crushed in advance by the crushing part and the crushing processing part and the crushed material is supplied to the eccentric side of the upper part of the screw, so that the larger material can be squeezed without increasing the size of the screw.

[0007] However, in this case, the structure of the conventional juicer for fixing and supporting the upper and lower ends of the screw rotating shaft cannot be eliminated, and therefore the inlet for feeding larger materials is formed to protrude outward at a position eccentric to one side of the upper part of the screw, rather than being formed in the center. As a result, the shape of the juicer becomes larger and more complicated, and further, the structure for crushing the material before juicing, such as the crushing part and the crushing processing part, becomes complicated.

[0008] Furthermore, when a relatively large material is fed into the enlarged inlet, the material does not encounter sufficient resistance in the inlet and therefore cannot cooperate with the screw and rotates idle, which results in a problem that the material is not easily cut. Summary of the invention

[0009] Therefore, the present invention is proposed to solve the above problems, and its purpose is to provide a juicer, which, in order to cut materials, allows the crushing card part that cooperates with the screw to enter the inside of the moving path for installing and disassembling the screw inside the shell to strengthen the mutual cooperation with the screw, thereby effectively cutting larger materials.

[0010] In addition, the object of the present invention is to provide a juicer, which allows the crushing clamp part that enters the installation and removal moving path of the screw to strengthen the mutual cooperation with the screw to be separated from the installation and removal moving path when the screw is removed from the shell and installed, thereby making it easy to install and remove the screw.

[0065] The detailed description and drawings include details of the embodiments.

[0066] The advantages and features of the present invention, as well as the methods for achieving these advantages and features, should be clearly understood by referring to the accompanying drawings and the embodiments described in detail below. However, the present invention is not limited to the embodiments disclosed below and can be implemented in various forms. This embodiment is only used to fully disclose the present invention and is provided to fully inform those skilled in the art of the scope of the invention, and the present invention should be defined by the scope of the claims. Throughout the specification, the same reference numerals refer to the same structural elements.

[0067] In addition, for the sake of convenience, the structures shown in the figures are arbitrarily shown, so the present invention is not necessarily limited to the structures shown in the figures. For the sake of clarity and convenience, the size or shape of the structural elements shown in the figures may be exaggerated. Therefore, the terms specifically defined in consideration of the structure and function of the present invention may vary according to the intention or practice of the user or operator, and such terms should be defined according to the content of the full text of this application document.

[0068] In the present application document, unless otherwise specified, “upper side”, “upper part”, “upper end” or similar terms refer to one side of the input material or a portion or end close thereto, and “lower side”, “lower part”, “lower end” or similar terms refer to the opposite side of one side of the input material or a portion or end close thereto.

[0069] Hereinafter, a juice extractor according to a first embodiment of the present invention will be described in detail with reference to the accompanying drawings.

[0070] Figure 1 is a three-dimensional diagram of a juice extractor according to a first embodiment of the present invention, Figure 2 and Figure 3 for Figure 1 Exploded stereogram of Figure 3 for Figure 1 A cutaway stereogram of Figure 4 and Figure 5 for Figure 2 An exploded perspective view of the screw shown, Figure 6 for Figure 2 A cross-sectional view of the screw shown.

[0071] The juice extractor according to the first embodiment of the present invention may include a housing 100 , a screw 200 , a crushing clamp 300 , and an operating portion 400 .

[0072] The housing 100 may be formed in a container shape with a fully open top surface, and an inlet 101 is formed on the open top surface. Therefore, as shown in the figure, even materials larger than the radius of the screw 200 can be put into the housing 100.

[0073] The total height of the shell 100 is set to be relatively higher than the height of the screw 200, so that a waiting space is formed on the upper inner side for the material introduced from the inlet 101 to wait before juicing. This waiting space is formed in a shape in which the cross-sectional area increases from the lower part to the upper part.

[0074] The housing 100 can accommodate the screw 200 at the lower inner portion, and the screw 200 can be inserted into or taken out of the housing 100 through the inlet 101, or when the screw 200 is arranged at the lower inner portion, the juice extraction material can be put into the housing 100 through the inlet 101. In addition, since the total height of the housing 100 is set to be relatively higher than the height of the screw 200, a waiting space can be formed at the upper inner portion of the housing 100 for the material inserted from the inlet 101 to wait before juice extraction, so there is no need to provide an additional hopper above the housing 100.

[0075] Although not shown in the figure, the housing 100 may be Figure 7The housing 100 is separated into a lower juicer for receiving the screw 200 and an upper hopper for forming a waiting space, and the joint between the lower juicer and the upper hopper can be configured to be detachable. In this way, when the housing 100 is separated into a lower juicer and an upper hopper, the material waiting space of the hopper can also be formed in a form in which the cross-sectional area is the same or decreases as it goes from the bottom to the top.

[0076] The screw 200 received in the housing 100 may be coupled to the driving shaft 11 of the driving body 10 disposed below the housing 100 , and thus may receive a driving force from the driving shaft 11 of the driving body 10 to rotate.

[0077] The housing 100 may be formed such that the wall thickness of the lower portion is greater than that of the upper portion. In particular, the lower portion of the center of the housing 100 is subjected to greater pressure during the process of crushing and squeezing the material by the screw 200, so it is preferably formed relatively thicker than the upper portion to ensure durability.

[0078] A guide rail 110 is formed on the inner wall surface of the housing 100 extending from the lower end of the waiting space to the upper end input port 101 , and a crushing clamp 300 can be detachably assembled on the guide rail 110 in a sliding manner. The upper end of the guide rail 110 is open at the upper end of the housing 100 .

[0079] Such a guide rail 110 may include a sliding opening 112 formed by being recessed from the inner wall surface of the housing 100 along the thickness direction, and a sliding groove 111 formed by extending on the inner side of the sliding opening 112 with an area relatively larger than that of the sliding opening 112. That is, the guide rail 110 composed of the sliding opening 112 and the sliding groove 111 may be formed in a substantially "T"-shaped cross-sectional shape, and the sliding groove 111 communicates with the internal space of the housing 100 through the sliding opening 112.

[0080] In order to facilitate the insertion of the moving part 410 described later, the sliding groove 111 and the sliding opening 112 can be formed into a shape in which the cross-sectional area increases from the lower end to the upper end. In addition, the moving part 410 and the blocking protrusion 411 can be formed into a shape in which the cross-sectional area decreases from the upper end to the lower end. Thus, when the moving part 410 is located at the upper part of the guide rail 110, the moving part 410 can move smoothly. In addition, when the moving part 410 is located at the lower part of the guide rail 110, the moving part 410 is in a state of being closely supported in the guide rail 110, so when cutting materials, it can stably support the crushing card part 300 that is subject to strong resistance.

[0081] A waterproof cylinder 140 with a through hole 142 may be formed protruding upward at the center of the bottom surface of the housing 100, through which the screw 200 may be coupled to the driving shaft 11 of the driving body 10. The waterproof cylinder 140 is formed protruding upward to prevent juice from flowing out through the through hole 142.

[0082] In addition, a juice discharge port 150 and a residue discharge port 160 are formed on the outer side of the lower end of the housing 100, respectively, and are spaced from each other. The juice discharge port 150 is used to discharge the juice squeezed from the material from the inside of the housing 100, and the residue discharge port 160 is used to discharge the remaining residue. Thus, the juice squeezed between the housing 100 and the screw 200 and moved to the inside of the screw 200 can be discharged to the outside through the juice discharge port 150 connected to the inside of the screw 200, and the residue remaining after the juice is squeezed between the housing 100 and the screw 200 can be discharged to the outside through the residue discharge port 160 connected to the lower end of the space between the housing 100 and the screw 200.

[0083] In addition, a protruding first rib 180 may be formed along the length direction on the inner side surface of the housing 100. As the screw 200 rotates, the material is squeezed or crushed by the interaction between the first rib 180 and the screw thread 230. Without the first rib 180, the juicing material cannot move downward and stagnates, or the squeezing force or crushing force may be low or cannot be generated.

[0084] In addition, a protruding second rib 185 may be formed on the inner side of the housing 100 along the length direction. The second rib 185 performs the function of moving the material put into the interior of the housing 100 downward and crushing the juicing material. The second rib 185 may perform the function of reinforcing the rigidity of the housing 100 and the function of guiding the juicing material to the space between the housing 100 and the screw 200. In addition, the second rib 185 may perform the function of adjusting the position of the screw 200 and adjusting the juicing space.

[0085] Such first rib 180 and second rib 185 may be formed to have different lengths from each other. The first rib 180 may be formed at the inner lower portion of the shell 100 to have a length corresponding to the outer circumferential surface of the screw 200, and the second rib 185 may be formed to have the following length: that is, the length is the length extending from the inner lower portion of the shell 100 to a position higher than the screw 200 and thus extending to a waiting space for the material to wait before juicing.

[0086] In addition, a plurality of third ribs 186 may be further formed on the inner side of the housing 100. The third ribs 186 may be formed between the plurality of first ribs 180 or between the plurality of second ribs 185.

[0087] Similar to the first rib 180 or the second rib 185 , the third rib 186 may be formed to extend in the length direction of the housing 100 , and the length of the third rib 186 may be formed to be shorter than that of the first rib 180 .

[0088] In the case where the third rib 186 is further formed, the number of ribs for crushing the object to be squeezed increases in sequence from the upper end portion to the lower end portion in the length direction of the housing 100. In other words, the object to be squeezed is crushed by the second rib 185 at the uppermost end of the housing 100, the object to be squeezed is crushed by the second rib 185 and the first rib 180 at the next height, and the object to be squeezed is crushed by the second rib 185, the first rib 180 and the third rib 186 at the next height, so that the object to be squeezed can be gradually crushed and moved to the lower portion of the housing 100 more smoothly.

[0089] The screw 200 is inserted into the shell 100 through the inlet 101 of the shell 100, and rotates around the rotation axis at the lower inner center of the shell 100, and squeezes and crushes the material entering between the shell 100 and the screw 200 while moving downward to extract juice.

[0090] Such a screw 200 may be configured to include a first module 210 and a second module 220 having two cylindrical shapes.

[0091] The first module 210 is formed to include a first body 211 having a hollow cylindrical shape with an open bottom, and a plurality of slits 212 formed along the outer circumference of the first body 211 and in a long length direction.

[0092] A screw thread 230 may be formed on an outer circumferential surface of the first body 211 and is oblique to the length direction.

[0093] The second module 220 may include a second body 221 having a cylindrical shape and a plurality of ribs 222 protruding from an outer surface of the second body 221 in a shape corresponding to the slit 212 of the first module 210 .

[0094] When the first module 210 and the second module 220 as described above are combined, since the inner diameter of the first body 211 of the first module 210 is larger than the outer diameter of the second body 221 of the second module 220, the first module 210 wraps the second module 220 in a manner of accommodating the second module 220 to be combined, and when the rib 222 of the second module 220 is inserted into the slit 212 of the first module 210 to be combined, the portion of the first body 211 where the slit 212 is not formed and the portion of the second body 221 where the rib 222 is not formed are combined in a radially overlapping manner.

[0095] At this time, the rib 222 of the second module 220 is inserted into the slit 212 of the first module 210, and a predetermined gap G is formed between the slit 212 and the rib 222 (see Figure 6 ). Juice can flow into the inner side of the screw 200 through the gap, and residues separated from the juice will remain in the space between the screw 200 and the housing 100.

[0096] Therefore, in this embodiment, the material is squeezed and crushed between the shell 100 and the screw 200 to be separated into juice and residue, wherein the juice flows into the interior of the screw 200 and is discharged through the juice discharge port 150, and the residue is moved to the bottom of the space between the shell 100 and the screw 200 and is separated and discharged through the residue discharge port 160.

[0097] In addition, the upper part of the first body 211 is formed so that the radius gradually decreases as it moves upward. As shown in the figure, the radius change caused by the change in height of the upper part of the first body 211 is greater than that of the lower part of the first body 211. The radius of the front end of the upper part of the first body 211 is the smallest, and it is formed so that the radius gradually increases as it moves downward. According to such a shape, a space is formed for transferring a larger material while the size gradually decreases under squeezing and crushing. In other words, since the diameter of the upper part of the first body 211 gradually increases as it moves downward, the size of the space for transferring the material formed by the first body 211 and the screw thread 230 gradually decreases along the transfer direction of the material. That is, through the rotation of the screw 200, the material is squeezed and crushed and its size gradually decreases, and it moves toward the bottom of the screw 200 along the screw thread 230 formed downward and along the gradually decreasing transfer space.

[0098] The screw thread 230 is formed to protrude in a spiral shape on the outer circumferential surface of the first module 210 and the second module 220, and the juice material is squeezed into the narrow gap between the screw 200 and the housing 100 and moved to the lower side through the screw thread 230. At this time, the screw thread 230 preferably protrudes to contact or approach the housing 100. As described above, the radius of the upper part of the first module 210 decreases as it approaches the upper part, so the screw thread 230 is formed so that its protruding height increases as it approaches the upper part of the first module 210.

[0099] The screw thread 230 may be formed into one or more, and in the present invention, one of the threads is formed to extend upwardly toward the first body 211 in a spiral shape as shown in the figure (hereinafter referred to as "the extension of the first screw thread 230-1"). Therefore, the first body 211 does not exist at the height where the extension of the first screw thread 230-1 is formed, so even if the extension of the first screw thread 230-1 is considered, a space where a material having a size greater than the radius of the screw 200 is located can be formed, and when the screw 200 rotates, the material can be crushed in the space by the interaction between the extension of the first screw thread 230-1 and the crushing clamp 300 formed on the inner side surface of the housing 100. At this time, since the surface of the screw thread 230 is formed to be inclined downward, the crushed material is moved downward along the screw thread 230 and juice is squeezed at the lower end of the screw 200.

[0100] In this way, the present invention gets rid of the previous structure of supporting both ends of the screw rotating shaft and rotating it, and only relies on the lower rotating shaft for support, so there is no need to set up a structure for supporting the upper rotating shaft above the screw. Therefore, the entire space above the screw 200 can be used, so that not only can large-sized materials be directly put in through the input port 101 above the screw 200 for juice extraction, but the screw 200 can also be installed and removed through the input port 101, so the housing 100 can be constructed as an integrated type.

[0101] At this time, if Figures 2 to 5 As shown, the shape of one end of the extension portion of the first screw thread 230-1 is formed as an arc that is recessed in a direction opposite to the direction in which the first screw thread 230-1 extends upward from the first body 211, so that the first screw thread 230-1 at the upper end can have a hook shape as a whole.

[0102] In addition, as shown in the figure, a second screw thread 230-2 may be formed spirally from the upper part of the first body 211 toward the lower part, and a plurality of threads 230-3 may be formed between the first screw thread 230-1 and the second screw thread 230-2 at the lower part of the first body 211. Therefore, the width between adjacent screw threads 230 formed on the first body 211 is formed to have a relatively wide interval in the upper part of the first body 211, and is formed to have a relatively narrow interval in the lower part of the first body 211 by the plurality of screw threads 230-1, 230-2, 230-3. That is, the function of crushing the larger juicing material is mainly performed on the upper side of the screw 200, and the function of juicing by crushing and squeezing is mainly performed on the lower side of the screw 200.

[0103] In addition, a plurality of residue guide ridges 240 protruding radially outward may be formed along the circumferential direction on the lower end of the second body 221. The residue guide ridges 240 perform the function of sweeping the residue separated by juicing and moved to the lower part of the space between the screw 200 and the housing 100 when the screw 200 rotates downward. In this way, the residue guide ridges 240 formed on the radial outer peripheral surface of the lower end of the screw 200 can smoothly remove the residue stuck in the lower end of the space between the screw 200 and the housing 100, thereby further improving the juicing efficiency.

[0104] A lower rotating shaft (not shown) protruding downward may be formed below the screw 200 , and the lower rotating shaft may be coupled to the driving shaft 11 of the driving body 10 through the through hole 131 of the waterproof cylinder 140 , thereby receiving a rotating force from the driving body 10 .

[0105] The crushing card part 300 is arranged on the inner wall surface of the shell 100 in a form of extending and protruding in a direction intersecting the rotation direction of the screw 200, and the crushing card part 300 is constructed in a form in which the thickness decreases from the side connected to the inner wall surface of the shell 100 to the other side as the protruding direction.

[0106] The length of the crushing clamp 300 protruding from the inner wall surface of the housing 100 is preferably set to be able to enter the moving path a for installing and removing the screw 200 in the interior of the housing 100 (see Figure 7 )’s interior.

[0107] That is, the crushing clamp 300 provides a similar effect to the second rib 185 in that it protrudes from the inner wall surface of the housing 100 to increase the friction of the material on the inner wall surface of the housing 100. However, since the second rib 185 has a limited protruding length for disassembling and assembling the screw 200, it cannot provide effective resistance when the material larger than the radius of the screw 200 is put into the waiting space, so that the first screw thread 230-1 may not be able to exert its crushing ability. On the contrary, the crushing clamp 300 enters the moving path a (refer to FIG. 2 ) for the movement of the screw 200 inside the housing 100. Figure 7 ) inside, it can provide greater resistance to materials larger than the radius of the screw 200, so that materials larger than the radius of the screw 200 will not idle in the waiting space inside the shell 100, but can be effectively cut by the first screw thread 230-1.

[0108] The lower end of the crushing card part 300 is preferably located at least near the upper end of the screw 200 where the first screw thread 230-1 extending upward toward the first main body 211 is located, so that the lower end of the crushing card part 300 can support the other side of the material during the process of the first screw thread 230-1 extending upward toward the first main body 211 cutting and crushing the material.

[0109] At this time, the protruding direction of the crushing clamp part 300 preferably extends vertically downward from the inner side surface of the housing 100, but may also be formed to have a predetermined angle.

[0110] The crushing clamp 300 may be divided into a first protrusion 310 at the upper center and a second protrusion 320 at the lower center, and the first protrusion 310 may have a protrusion length that is relatively longer than that of the second protrusion 320. Although the second protrusion 320 has a protrusion length shorter than that of the first protrusion 310, it is preferred that the second protrusion 320 has a protrusion length that is longer than that of the second rib 185 of the housing 100.

[0111] Thus, larger materials introduced through the inlet 101 of the shell 100 can be crushed by the interaction between the first protrusion 310 and the first screw thread 230-1, and smaller materials can be crushed by the interaction between the second protrusion 320 and the first screw thread 230-1, thereby improving the crushing efficiency of materials of various sizes.

[0112] On the other hand, the crushing card part 300 is described as an example consisting of the first protrusion 310 and the second protrusion 320 with different protrusion lengths as described above, but is not limited to this. It can also be composed of more than three protrusions whose protrusion lengths become shorter from the upper end to the lower end or an inclined surface in the form of an oblique line.

[0113] The screw 200 of the present invention may be formed in a form in which the screw thread 230 extends upwardly from the first body 211. At this time, the end of the screw thread 230 extending upwardly from the first body 211 is located at the lower part of the material waiting space inside the housing 100. At this time, even if a large material such as apples and oranges in a state of not being pre-cut is put into the waiting space through the input port 101 of the housing 100, the screw thread 230 extending upwardly from the first body 211 can effectively crush the material by interacting with the crushing clamp 300 protruding from the inner side surface of the housing 100 while rotating. That is, in a state in which the crushing clamp 300 clamps the large material, the material can be crushed by squeezing and mutual cutting caused by the rotation of the screw thread 230 extending upwardly from the first body 211. At this time, when the screw 200 rotates, the crushed material can easily move to the lower part of the screw 200 along the surface of the screw thread 230 inclined downward.

[0114] The operating portion 400 is used to make the crushing clamp 300 enter or leave the interior of the moving path for installing and removing the screw rod 200 .

[0115] The crushing card part 300 can provide resistance to larger materials inside the shell 100, but because the crushing card part 300 is arranged on the moving path inside the shell 100 for installing and removing the screw 200, it is difficult to install and remove the screw 200 when the crushing card part 300 is arranged in the shell 100.

[0116] Therefore, in this embodiment, the pulverizing clamp 300 can enter or leave the moving path for installing and removing the screw 200 through the operating part 400, so that the disassembly and assembly of the screw 200 relative to the housing 100 becomes easy.

[0117] The operation unit 400 includes a moving member 410 detachably assembled to the inner wall surface of the housing 100 while supporting the crushing clamp 300 , and a cover 420 connected to the moving member 410 and used to open and close the opening of the housing 100 .

[0118] Specifically, the moving member 410 may be constructed of a rod-shaped length member that can be inserted into the sliding groove 111 through the upper end opening of the guide rail 110, and a blocking protrusion 411 may be formed on one surface of the moving member 410. The blocking protrusion 411 can be inserted into the sliding opening 112 while supporting the crushing clamp 300 on one side of its lower end. That is, when the moving member 410 is inserted into the sliding groove 111 of the guide rail 110, the blocking protrusion 411 of the moving member 410 blocks the sliding opening 112, thereby preventing a portion of the material from flowing into the sliding groove 111 during the cutting and crushing of the material.

[0119] On the other hand, the crushing clamp 300 disposed on one side of the lower end portion of the blocking protrusion 411 may be formed integrally with the moving member 410 .

[0120] The moving member 410 is formed in a shape in which the cross-sectional area decreases from the upper end to the lower end, so that it can be easily inserted into the sliding groove 111 of the guide rail 110; the blocking protrusion 411 can also be formed in a shape in which the cross-sectional area decreases from the upper end to the lower end, so that it can be easily inserted into the sliding opening 112. At this time, when the moving member 410 is completely inserted into the guide rail 110, the outer side surface of the moving member 410 is preferably in close contact with the inner side surface of the guide rail 110.

[0121] The length of the moving member 410 is set to correspond to the length of the guide rail 110, so that when the moving member 410 is fully inserted into the guide rail 110, the upper end of the moving member 410 is located at the upper end of the housing 100. At this time, a first rotating portion 412 is formed on the upper end of the moving member 410 in an extended form.

[0122] The cover 420 is used to open and close the input port 101 of the housing 100. The cover 420 may be formed in a disc shape, and a first rotation coupling portion 422 that can be rotatably coupled to the first rotation portion 412 of the moving member 410 is formed on one side of the cover 420. Thus, the cover 420 can rotate around the first rotation portion 412 and open and close the input port 101 of the housing 100 according to the rotation position, and the cover 420 can be pulled upward to easily remove the moving member 410 inserted into the guide rail 110.

[0123] The cover 420 may further be formed with an additional injection hole for limiting the size of the material to be injected into the housing 100 to within a predetermined range.

[0124] A handle 423 for rotating the cover is formed on the other side of the cover 420 .

[0125] In addition, a buckle 423a is formed on the handle 423, and a buckle coupling part 102 capable of coupling with the buckle 423a is formed on the housing 100 at a position where the lid 420 closes the input port 101. The buckle 423a and the buckle coupling part 102 can be coupled to each other in a state where the input port 101 of the housing 100 is closed by the lid 420, thereby restricting the lid 420 from rotating arbitrarily toward the opening side. Moreover, the buckle 423a is preferably constructed in the following form: in the process of pressing the handle 423 downward to rotate the lid 420 toward the closing side, the buckle 423a can be coupled with the buckle coupling part 102; in the process of lifting the handle 423 to rotate the lid 420 toward the opening side, the buckle 423a can be released from the buckle coupling part 102.

[0126] The moving member 410 may be configured to fix the assembly position of the moving member 410 relative to the housing 100 when the cover 420 closes the inlet 101. To this end, the cover 420 may include a fixing portion 421, which can fix the assembly position of the moving member 410 or release the fixing according to the opening and closing state of the inlet 101.

[0127] The housing 100 is provided with a first slot 113, which can be coupled to the fixing portion 421 when the cover 420 closes the inlet 101. In order to more stably maintain the assembly position of the moving component 410, a second slot 413 communicating with the first slot 113 may be formed at the upper end of the moving component 410.

[0128] The fixing portion 421 can be formed in the form of a protrusion as follows: when the cover 420 is rotated to a position closing the inlet 101, the protrusion can be inserted into the first slot 113 and the second slot 413 to fix the assembly position of the movable part 410; when the cover 420 is rotated to a position fully opening the inlet 101, the protrusion can be disengaged from the first slot 113 and the second slot 413 to release the fixation of the position of the movable part 410.

[0129] Moreover, the first card slot 113, the second card slot 413 and the fixing portion 421 can be set in multiple numbers, thereby providing the following fixing force: during the cutting and crushing process of the material, the fixing force can fully prevent the moving component 410 from moving arbitrarily in the guide rail 110 due to the pressure applied to the crushing card portion 300.

[0130] In the accompanying drawings, Figure 7 It is a side sectional view of a juice extractor according to a first embodiment of the present invention. Figure 8 It is a top cross-sectional view of a juice extractor according to a first embodiment of the present invention. Fig. 9 2 is a cross-sectional view showing a state where the lid of the juice extractor according to the first embodiment of the present invention is opened. Fig.10 and Fig.11 1 is a diagram showing a fixed state and a released state of a moving part in a juice extractor according to a first embodiment of the present invention. Fig.12 It is a figure which shows the state which separated the screw from the housing|casing of the juice extractor of the 1st embodiment of this invention.

[0131] First, refer to Figure 7 and Figure 8 The juice extraction process is described as follows: the material in the waiting space at the upper portion of the housing 100 after being fed from the inlet 101 is cut and crushed by the interaction between the first screw thread 230 - 1 and the crushing clamp 300 and then transferred to the lower portion.

[0132] Specifically, larger materials introduced through the inlet 101 of the housing 100 may be crushed by the interaction between the first protrusion 310 and the first screw thread 230 - 1 , and smaller materials may be crushed by the interaction between the second protrusion 320 and the first screw thread 230 - 1 .

[0133] At this time, the crushing clamp part 300 is arranged inside the shell 100 to enter the moving path a for the screw 200 to move, thereby providing greater resistance to materials larger than the radius of the screw 200. Therefore, larger materials will not idle in the waiting space inside the shell 100, but can be effectively cut by the first screw thread 230-1.

[0134] In addition, the movable component 410 supporting the shredding card part 300 can be detachably assembled on the inner wall surface of the shell 100, and the guide rail 110 combined with the movable component 410 extends on the inner wall surface of the shell 100 along a direction intersecting the rotation direction of the screw 200, thereby providing effective support force for the lateral pressure acting on the shredding card part 300, and thereby preventing the movable component 410 from being arbitrarily separated from the guide rail 110 during the cutting process of the material.

[0135] Next, the material between the housing 100 and the screw 200 is squeezed and crushed while being moved downward along the screw 200. In this process, the squeezed juice flows into the interior of the screw 200 and is finally discharged through the juice discharge port 150 of the housing 100, and the residue separated from the juice is moved to the lower part of the space between the housing 100 and the screw 200 and is finally discharged through the residue discharge port 160 of the housing 100.

[0136] After the squeezing of the material is completed, it is necessary to disassemble the screw 200 from the housing 100 for cleaning.

[0137] Next, refer to Figures 9 to 12 The disassembly process of the screw 200 is described as follows.

[0138] First, if Fig. 9 As shown, the first rotating joint part 422 provided on one side of the cover 420 is rotatably coupled to the first rotating part 412 provided on the upper end of the moving member 410. Thus, when the cover 420 is rotated toward the opening side, the cover 420 can rotate around the first rotating part 412 and detach from the upper end of the housing 100, thereby opening the input port 101 of the housing 100.

[0139] In addition, a buckle 423a is formed on the handle 423, and a buckle coupling part 102 capable of coupling with the buckle 423a is formed on the housing 100 at a position where the cover 420 closes the inlet 101. The buckle 423a and the buckle coupling part 102 can be coupled to each other when the cover 420 closes the inlet 101 of the housing 100, thereby restricting the cover 420 from rotating arbitrarily toward the open side. Moreover, the buckle 423a is preferably constructed in the following form: in the process of pressing the handle 423 in order to rotate the cover 420 toward the closed side, the buckle 423a can be coupled with the buckle coupling part 102; in the process of lifting the handle 423 in order to rotate the cover 420 toward the open side, the buckle 423a can be released from the buckle coupling part 102.

[0140] like Fig.10 As shown, in the state where the moving member 410 is completely inserted into the guide rail 110 of the housing 100, the second card slot 413 of the moving member 410 is connected to the first card slot 113 of the housing 100. If the cover 420 is rotated in the direction of closing the input port 101 of the housing 100 in this state, the fixing portion 421 provided on one side of the bottom surface of the cover 420 passes through the first card slot 113 of the housing 100 and is inserted into the second card slot 413 of the moving member 410. Thus, the position of the moving member 410 is fixed in the guide rail 110, so that the moving member 410 can be prevented from sliding arbitrarily due to external force when inserted into the guide rail 110.

[0141] Next, if Fig.11 As shown, if the cover 420 is rotated in the direction of the input port 101 of the open shell 100, the fixing portion 421 arranged on one side of the bottom surface of the cover 420 disengages from the second slot 413 of the movable part 410 and the first slot 113 of the shell 100, thereby releasing the fixation of the movable part 410, and the movable part 410 is in a state of being able to move in the direction of separation from the guide rail 110.

[0142] In this state, if Fig.12 As shown, if the cover 420 is pulled upward, the moving member 410 connected to the cover 420 can be lifted together with the cover 420 and separated from the guide rail 110 of the housing 100, and the crushing clamp 300 supported on the moving member 410 can also be separated from the housing 100 together with the moving member 410. That is, if the cover 420 connected to the upper end of the moving member 410 is used, the moving member 410 inserted in the guide rail 110 can be easily separated.

[0143] When the crushing card part 300 is separated from the housing 100 together with the moving member 410 , the crushing card part 300 is separated from the moving path a for attaching and detaching the screw 200 inside the housing 100 , so the screw 200 can be easily separated from the housing 100 .

[0144] Hereinafter, a juice extractor according to a second embodiment of the present invention will be described in detail with reference to the accompanying drawings.

[0145] In the accompanying drawings, Fig.13 It is a perspective view of a juice extractor according to a second embodiment of the present invention. Fig.14 and Fig.15 for Fig.13 Exploded three-dimensional diagram. Fig.16 It is a side sectional view of a juice extractor according to a second embodiment of the present invention. Fig.17 It is a top cross-sectional view of a juice extractor according to a second embodiment of the present invention. Fig.18 It is a figure which shows the state which separated the screw from the housing|casing of the juice extractor of the 2nd embodiment of this invention.

[0146] The juice extractor according to the second embodiment of the present invention may include a housing 100 , a screw 200 , a crushing clamp 300 , and an operating portion 400 .

[0147] The juice extractor of the second embodiment of the present invention is constructed as follows: the cover 420 of the operating part 400 is rotatably supported on one side of the upper end of the housing 100, and the moving part 410 sliding along the guide rail 110 formed on the inner wall surface of the housing 100 is connected to the cover 420 through a connecting rod 430. The moving part 410 moves up and down along the guide rail 110 in conjunction with the rotation of the cover 420, and the crushing clamp 300 enters or leaves the inside of the moving path for installing and removing the screw 200. In this regard, the juice extractor of the second embodiment is structurally different from the first embodiment.

[0148] On the other hand, except for the operating part 400 and the partial structure related to the operation of the operating part 400, the remaining structure is the same as the corresponding structure of the first embodiment, and the function related to the juicing of the material is also the same as that in the first embodiment, so the specific description of the same structure and function is omitted.

[0149] The total height of the housing 100 is set to be relatively higher than the height of the screw 200, so that a waiting space is formed at the inner upper part for the materials put in from the input port 101 to wait before juicing, and this waiting space is formed in a shape in which the cross-sectional area increases from the lower part to the upper part. That is, the inner wall surface of the inner upper part of the housing 100 connected to the waiting space has a predetermined inclination, and since the guide rail 110 for sliding the crushing card 300 is formed on the inner wall surface of the inner upper part of the housing 100, the crushing card 300 moving along the guide rail 110 can enter the inside of the moving path a for installing and removing the screw 200 when it moves downward along the guide rail 110, and can leave the moving path a for installing and removing the screw 200 when it moves upward along the guide rail 110.

[0150] The operating part 400 includes: a moving part 410, which can be slidably assembled on the guide rail 110 while supporting the crushing card part 300; a cover 420, which is rotatably supported on one side of the upper end of the shell 100 and opens and closes the input port 101 of the shell 100 according to the rotation position; and a connecting rod 430, whose two ends are respectively connected to the cover 420 and the moving part 410 in a rotatable state, so that the moving part 410 is linked to the rotation of the cover 420 and moves along the guide rail 110.

[0151] In order to rotate the cover 420, a second rotating portion 121 is formed on one side of the upper end of the shell 100, and a second rotating coupling portion 423 which can be rotatably coupled to the second rotating portion 121 is formed on one side of the cover 420, so that the cover 420 can be rotated relative to the shell 100 around the second rotating portion 121 to open and close the inlet 101.

[0152] In addition, a first rotation support portion 414 to which the lower end of the connecting rod 430 is rotatably connected is formed on the upper end of the moving member 410 , and a second rotation support portion 424 to which the upper end of the connecting rod 430 is rotatably connected is formed on the bottom surface of the cover 420 .

[0153] This connecting rod 430 performs the following functions: when the cover 420 rotates to a position closing the inlet 101, the movable part 410 moves toward the lower side of the guide rail 110; when the cover 420 rotates to a position opening the inlet 101, the movable part 410 moves toward the upper side of the guide rail 110.

[0154] The crushing clamp 300 is formed in the shape of a blade capable of cutting materials. Therefore, if the cover 420 is rotated to the open position, after the material is put into the inside of the housing 100 through the input port 101 of the housing 100, so that the cover 420 is rotated to the closed position, the moving part 410 connected to the cover 420 through the connecting rod 430 descends along the guide rail 110. During this process, the crushing clamp 300 supported on the moving part 410 can poke the material put into the inside of the housing 100 while pressurizing the screw 200 and fixing the position of the material. Therefore, the material whose size is larger than the radius of the screw 200 will not idle in the waiting space inside the housing 100, but can be effectively cut by the first screw thread 230-1.

[0155] Reference Fig.16 and Fig.17 The juice extraction process is described as follows: The material introduced from the inlet 101 and located in the waiting space at the upper inner side of the housing 100 is crushed and transferred downward by the interaction between the first screw thread 230 - 1 and the crushing clamp 300 .

[0156] At this time, the crushing clamp 300 is arranged to enter the moving path a, wherein the moving path a is the path for the screw 200 to move inside the housing 100 in order to install and remove the screw 200. Thus, the crushing clamp 300 can provide strong resistance to materials larger than the radius of the screw 200, so that the larger materials will not idle in the waiting space inside the housing 100, but can be effectively cut and crushed by the first screw thread 230-1.

[0157] In addition, the movable component 410 supporting the shredding card part 300 is engaged on the guide rail 110 on the inner wall surface of the shell 100, and the guide rail 110 combined with the movable component 410 extends on the inner wall surface of the shell 100 along a direction intersecting with the rotation direction of the screw 200, thereby providing effective support force for the lateral pressure acting on the shredding card part 300, and thereby preventing the movable component 410 from being separated from the guide rail 110 at will during the cutting process of the material.

[0158] After the juicing of the material is completed, it is necessary to disassemble the housing 100 and the screw 200 for cleaning.

[0159] That is, Fig.18 As shown, the cover 420 of the operating part 400 is rotatably connected to the first rotating part 412 on the upper end side of the shell 100, the movable part 410 is arranged to be movable up and down along the guide rail 110 on the inner wall of the shell 100, and the two ends of the connecting rod 430 are rotatably connected to the first rotating support part 414 of the movable part 410 and the second rotating support part 424 of the cover 420 respectively.

[0160] Therefore, when the cover 420 is rotated to open the inlet 101 of the housing 100 , the link 430 connecting the cover 420 and the moving member 410 pulls the moving member 410 upward, so that the moving member 410 moves to the upper part of the guide rail 110 .

[0161] At this time, since the waiting space of the shell 100 is formed in a shape in which the cross-sectional area increases from the lower part to the upper part, when the moving part 410 moves to the upper part of the guide rail 110, the crushing card part 300 can be separated from the moving path a used for installing and disassembling the screw 200, thereby ensuring space for separating the screw 200 from the shell 100.

[0162] Hereinafter, a juice extractor according to a third embodiment of the present invention will be described in detail with reference to the accompanying drawings.

[0163] In the accompanying drawings, Fig.19 It is a three-dimensional diagram of a juice extractor according to a third embodiment of the present invention. Fig. 20 and Fig.21 for Fig.19 Exploded three-dimensional diagram. Fig. 22 It is a side sectional view of a juice extractor according to a third embodiment of the present invention. Fig.23 It is a top cross-sectional view of a juice extractor according to a third embodiment of the present invention. Fig.24 FIG. 1 is a diagram showing a state where a screw is separated from a housing of a juice extractor according to a third embodiment of the present invention.

[0164] The juice extractor according to the third embodiment of the present invention may include a housing 100 , a screw 200 , a crushing clamp 300 , and an operating portion 400 .

[0165] The juice extractor of the third embodiment of the present invention is constructed as follows: the crushing card part 300 is inserted into or out of the inner side of the housing 100 through the through hole 131 formed on the side wall of the housing 100, thereby entering or out of the inside of the moving path a for installing and removing the screw 200, and in order to move the crushing card part 300, the crushing card part 300 is guided to enter or out of the inside of the moving path a according to the rotation position in a state where the moving member 410 supporting the crushing card part 300 is rotatably supported on the outer wall surface of the housing 100. In this respect, the juice extractor of the third embodiment is structurally different from the above-mentioned embodiments.

[0166] On the other hand, except for the operating part 400 and the partial structure related to the operation of the operating part 400, the remaining structure is the same as the corresponding structure of the first embodiment, and the function related to the juicing of the material is also the same as that in the first embodiment, so the specific description of the same structure and function is omitted.

[0167] The through hole 131 is used to determine the position of the crushing clamp 300 , and therefore the position of the through hole 131 is preferably set to a position where the crushing clamp 300 inserted into the housing 100 can interact with the screw thread 230 .

[0168] The operating part 400 is used to make the crushing card part 300 enter or leave the interior of the moving path a used for installing and disassembling the screw 200. The operating part 400 includes: a moving part 410, which is rotatably supported on the outer wall surface of the shell 100 while supporting the crushing card part 300, so that the crushing card part 300 can enter and exit the internal space of the shell 100 through the through hole 131; and a cover 420, which is connected to the upper end of the moving part 410, and opens and closes the input port 101 at the upper end of the shell 100 according to the rotation position of the moving part 410.

[0169] Specifically, a third rotating portion 132 is formed below the through hole 131 of the outer wall of the housing 100, and a third rotating coupling portion 415 rotatably coupled to the third rotating portion 132 is formed at the lower end of the moving member 410. Thus, when the moving member 410 rotates in a direction close to the outer wall of the housing 100, the crushing card portion 300 supported on the moving member 410 protrudes into the inner space of the housing 100 through the through hole 131 and enters the inside of the moving path a for mounting and dismounting the screw 200. Conversely, when the moving member 410 rotates in a direction away from the outer wall of the housing 100, the crushing card portion 300 supported on the moving member 410 is separated from the outer side of the housing 100 through the moving member 410 and is separated from the moving path a for mounting and dismounting the screw 200.

[0170] Here, when the moving member 410 makes the crushing card part 300 enter the moving path a for installing and removing the screw rod 200, the moving member 410 is in close contact with the outer wall surface of the housing 100, so that the further rotation of the moving member 410 is limited. In addition, when the moving member 410 makes the crushing card part 300 disengage from the moving path a for installing and removing the screw rod 200, the stopper 416 provided at the lower end of the moving member 410 is in close contact with the outer wall surface of the housing 100, so that the further rotation of the moving member 410 is limited. At this time, it is preferred that the end portion of the crushing card part 300 is set to be flush with the inner wall surface of the housing 100, so as to prevent the crushing card part 300 from completely disengaging from the through hole 131.

[0171] The crushing card part 300 is set to have an arcuate cross-sectional shape that is concentric with the rotation center of the moving member 410, so that it can rotate with the moving member 410 around the third rotating part 132 and enter and exit the interior of the housing 100 through the through hole 131. That is, in the process of the crushing card part 300 entering and exiting the interior of the housing 100 through the through hole 131, the through hole 131 can remain blocked by the crushing card part 300, thereby preventing impurities from flowing into the interior of the housing 100 from the outside through the gap between the through hole 131 and the crushing card part 300, or preventing the material inside the housing 100 from flowing out to the outside of the housing 100 through the through hole 131.

[0172] In addition, a double guide rib 133 is formed on the outer wall surface of the housing 100. When the moving part 410 is in close contact with the outer wall surface, the guide rib 133 wraps around both sides of the moving part 410. When the crushing clamp 300 helps to cut the material by interacting with the screw 200, a large lateral pressure will act on the crushing clamp 300. Since the crushing clamp 300 is supported in the through hole 131, the moving part 410 connected to the crushing clamp 300 on the outer wall surface side of the housing 100 is supported by the double guide rib 133, so that a stable support force can be provided for the lateral pressure.

[0173] The cover 420 may be configured to open and close the inlet 101 at the upper end of the housing 100 according to the rotation position of the moving part 410 when one side of the cover 420 is connected to the upper end of the moving part 410 . The cover 420 may be integrally formed with the moving part 410 , but is not limited thereto.

[0174] That is, the cover 420 connected to the movable part 410 can perform the function of an operating rod for rotating the movable part 410. If the cover 420 is moved toward the closing side, the movable part 410 connected to the cover 420 can be rotated in a direction of being tightly attached to the outer wall surface of the shell 100; if the cover 420 is moved to the opening side, the movable part 410 connected to the cover 420 can be rotated in a direction of being separated from the outer wall surface of the shell 100.

[0175] like Fig.24 As shown in FIG. 1 , if the cover 420 is moved toward the open side, the moving member 410 connected to the cover 420 rotates in a direction away from the outer wall surface of the housing 100 with the third rotating portion 132 of the housing 100 as the center. At this time, the crushing card part 300 connected to the moving member 410 moves toward the outside of the housing 100 through the through hole 131 based on the rotation of the moving member 410, thereby leaving the moving path a for installing and removing the screw 200.

[0176] When the cover 420 is moved toward the open side, the crushing clamp 300 is separated from the moving path a inside the housing 100 for attaching and detaching the screw 200 , so that a space for separating the screw 200 from the housing 100 can be ensured.

[0177] The scope of the present invention is not limited to the above-mentioned embodiments, and can be implemented by various forms of embodiments within the scope of the attached claims. Within the scope of the spirit of the present invention claimed in the claims, various scopes that can be modified by technicians in the technical field to which the present invention belongs also fall within the scope recorded in the claims of the present invention.
