Food processor with residue and juice separation and drying functions

Abstract

The present invention relates to a food processor with residue and juice separation and spin-drying functions. A driving part, a telescopic part, a screw and a nut, a single nut and other structures are arranged inside a rotating rod. The vertical movement of the driving part, the telescopic part, the screw and the nut, the single nut and other structures realizes the rise or fall of an inner magnetic attraction part. The rise or fall action can drive the rotating part or a cutter to rise or fall through the outer magnetic attraction part, thereby realizing the crushing of food to be processed when the cutter rotates and the throwing out of juice in the residue when the rotating part rotates. Due to the vertical relative displacement between the tool and the rotating part, the tool can more efficiently crush the food to be processed placed in the rotating part; secondly, there is no threaded fit between the tool and the rotating rod, and the residue is not easy to be retained, and the phenomenon of massive reproduction of pathogens due to the corruption of residues in the prior art will not occur; in addition, the surface of the rotating rod is flat, and the problem of massive reproduction of pathogens due to the corruption of external thread residues and the impact on the lifting and lowering of the tool (vertical movement) in the prior art will not occur; in the entire processing process, the rotating rod seals the structure inside it, and the whole is easy to disassemble and clean; finally, the closed rotating rod has a certain damping effect on the internal magnetic suction part of the lifting movement inside it, avoiding the vibration, noise and other hazards caused by its rapid rise or rapid descent and violent impact on other structures.

Description

Technical Field

[0001] The invention belongs to the technical field of food processing, and relates to a food processor, in particular to a food processor with residue and juice separation and drying functions. Background Art

[0002] Food processor is a processing equipment that uses a motor to drive the cutter to crush the food. The working speed of the food processor with the function of separating the residue and juice and drying is generally 16000-30000 rpm. It can break the cell wall of the cells in the food and fully release the vitamins, minerals, phytochemicals, proteins and water in the cells. It can be used to process soy milk, juice, thick soup, rice paste, grain porridge, sauce, fish soup, smoothie, Chinese medicinal materials, etc. It is a modern home health care and health appliance product.

[0003] A volumetric food processor with a barrel body is used for crushing beans, extracting nutrients after frying, and can also be used for extracting juice from crushed fruits and vegetables. The structure of this type of food processor is: including a power unit (with a motor as the core), a knife shaft, a knife, a barrel body, a machine body and an electronic control device. The machine body can be a machine base or a machine head. The machine base is set below the barrel body, the output shaft of the motor is set upward and connected to the knife shaft at the bottom of the barrel body, and the knife is installed on the knife shaft; the machine head is set above the barrel body, the output shaft of the motor is set downward and the knife is installed at the lower end; in another case, an extension part located on the side of the barrel body is set at one end of the machine base, and a motor is set in the extension part. The motor drives the knife on the knife shaft located below the barrel body through a transmission mechanism. Regardless of the structure, the rotation of the knife can crush the food placed in the barrel body or the food in the water in the barrel body into food liquid. The electronic control device is responsible for overall control.

[0004] In the above structure, when the food in the barrel is crushed, its liquid and the crushed solids are mixed in the barrel. Although the solid particles are very fine, the taste is still poor when people eat it, such as: bean dregs particles in soy milk, peel particles in juice, etc. People can pour out the solid-liquid mixture in the barrel and filter it through a filter net or other structures, but the operation becomes complicated and the filtering effect is not good.

[0005] After searching, two patents were found, specifically:

[0006] 1. The invention patent with the publication number TW201238540 discloses a slag-juice separation device, in which a rotating shaft 12 and a slag collecting component 3 are arranged in a container 2, and a shaft tube 33 and a rotating component 34 are arranged in the slag collecting component. The rotating component 34 is provided with a blade part 342, and the shaft tube has an internal thread 331 and is engaged with the threaded part 14 of the rotating shaft.

[0007] When the rotating shaft rotates in one direction, the slag collecting component moves downward, and when the rotating component is coupled with the driving part 15, the blade part rotates at a high speed to crush the food in the slag collecting component.

[0008] When the rotating shaft rotates in another direction, the slag collecting component moves upward, and when it hits the cover 22 or the machine base 1, the slag collecting component continues to rotate to throw out the internal liquid, while the slag remains in the slag collecting component.

[0009] 2. The invention patent with announcement number CN103976630 discloses a slag-juice separation device, which is improved on the basis of the above patent, and a blade 14 is provided on the outer edge of the sleeve 13.

[0010] When the rotating shaft rotates in one direction, the slag collecting component is combined with the support seat 25, and the sleeve rotates under the drive of the transmission part 122 to crush the food in the slag collecting component.

[0011] When the rotating shaft rotates in another direction, the slag collecting component moves upward, and when it moves to the upper end of the rotating shaft, it rotates synchronously with the rotating shaft through the second meshing portion 33 or the open groove 36 and other structures, and the liquid inside is thrown out, while the slag remains in the slag collecting component.

[0012] There are several problems with the above patent, specifically:

[0013] 1. The blade portion of Patent 1 is restricted at the lowermost end of the slag collecting component, and its upper end is embedded in the slag collecting component. When the rotating component is driven by the driving part to rotate, there will be a problem of synchronous rotation of the slag collecting component and the rotating component due to excessive friction between the rotating component and the slag collecting component. At this time, the crushing effect of the blade portion becomes worse.

[0014] 2. The blade portion of Patent 1 is located relatively low, and the blade of Patent 2 is limited by the height of the sleeve. Both cannot make relative vertical displacement in the slag collecting component, and their crushing efficiency needs to be improved.

[0015] 3. Solids can easily penetrate into the interior of the sleeves of Patents 1 and 2 and the gaps between the rotating component and the slag collecting component of Patent 1, which not only causes a sharp increase in resistance during rotation, but also easily causes corruption and deterioration, producing pathogenic bacteria.

[0016] 4. The rotating shafts of Patents 1 and 2 both have external threads. Due to the very high rotation speed, the external threads need to have a greater depth and a smaller rise angle to reduce the sleeve lifting and lowering speed. This means that the effective length of the external threads will be relatively long, and solids are easily adhered therein, which is not only difficult to clean, but will also produce pathogenic bacteria due to corruption and deterioration, and will cause wear of the external threads of the rotating shaft and the internal threads of the sleeve or obstruction of the mutual rotation and engagement between the two, ultimately resulting in problems such as increased noise and shaking during engagement.

[0017] 5. The rotating shaft of Patents 1 and 2 rotates at a relatively high speed, while the sleeve mounted thereon rises or falls at a relatively fast speed. When the sleeve and other structures thereon run to the upper or lower end of the rotating shaft, a relatively large impact will be caused on the other structures, which is not conducive to safe operation, and will generate relatively large noise and vibration of the entire machine, and will also affect the mechanical strength of other structures on the sleeve, resulting in a reduction in service life.

The rising or falling action can drive the rotating part or the cutter to rise or fall through the external magnetic part, thereby realizing the crushing of the food to be processed when the cutter rotates and the throwing out of the juice in the residue when the rotating part rotates. Due to the vertical relative displacement between the tool and the rotating part, the tool can more efficiently crush the food to be processed placed in the rotating part; secondly, there is no threaded fit between the tool and the rotating rod, and the residue is not easy to be retained, and the phenomenon of massive reproduction of pathogens due to the corruption of residues in the prior art will not occur; in addition, the surface of the rotating rod is flat, and the problem of massive reproduction of pathogens due to the corruption of external thread residues and the impact on the lifting and lowering of the tool (vertical movement) in the prior art will not occur; in the entire processing process, the rotating rod seals the structure inside it, and the whole is easy to disassemble and clean; finally, the closed rotating rod has a certain damping effect on the internal magnetic suction part of the lifting movement inside it, avoiding the vibration, noise and other hazards caused by its rapid rise or rapid descent and violent impact on other structures.

[0244] The present invention is further described below in conjunction with examples. The following examples are illustrative rather than restrictive, and the protection scope of the present invention cannot be limited by the following examples.

[0245] The tool mentioned in the present invention refers to the general term for the crushing tool device or crushing device of the food processor, which includes collision crushing tool, shearing crushing tool, grinding device with dynamic and static grinding head, etc. It can be driven by the power unit of the food processor to rotate or turn to crush the food.

[0246] In particular, the shearing type crushing tool includes a main tool and an auxiliary tool. In the shearing type crushing tool, the main tool is the main part, the main tool is set on the rotating rod and driven by the rotating rod, and the auxiliary tool is set on the inner edge of the rotating part. When there is a speed difference between the main tool and the auxiliary tool, the food is sheared and crushed (but when the distance between the two is too far, the shearing and crushing effect is weak). Therefore, for the shearing type crushing tool, the main focus is on the working state of the main tool, and the auxiliary tool is not described. For example, when the tool rotation is involved in the present invention, if it involves a shearing type crushing tool, the statement describes the state of the main tool rotation, and omits the description of the auxiliary tool.

[0247] The grinding device with a dynamic and static grinding head includes a dynamic grinding head and a static grinding head. The dynamic grinding head is the main part, which is the "tool" mentioned in the present invention, and the static grinding head is equivalent to the "auxiliary tool". The dynamic grinding head is mounted on the rotating rod and driven by the rotating rod, and the static grinding head is arranged on the inner edge of the rotating part. Therefore, for the grinding device with a dynamic and static grinding head, the working state of the dynamic grinding head is mainly concerned, and the static grinding head is not described.

[0248] The power unit drives the rotating rod to rotate, which includes both the power unit directly driving the rotating rod to rotate and driving the rotating rod to rotate through other transmission devices.

[0249] A food processor with residue and juice separation and drying functions, such as Figures 1 to 23As shown, it includes a power unit 17, a cutter 7 and a barrel 5, the power unit is provided with an output shaft 16, and for a food processor whose base is arranged below the barrel, the barrel and the base are separately arranged (such as Figure 1 ), and the barrel and the base are an integrated structure. Figure 1 As shown, the barrel and the base are separately arranged, a half coupling 14 is provided at the upper end of the output shaft, and another half coupling is provided at the end below the lower section of the rotating rod, and the two half couplings 14 are connected to each other, and the output shaft can drive the rotating rod to rotate. For the barrel and the base as an integrated structure, the output shaft can be directly connected to the rotating rod or the output shaft and the rotating rod are an integrated structure.

[0250] An end cover 2 is provided on the barrel body, and a handle 1 is provided on the outer wall of the barrel body. The innovation of the present invention lies in: it also includes a rotating rod 4 and a rotating part 21, the rotating rod is partially located in the barrel body or is completely located in the barrel body, the power unit drives the rotating rod to rotate, the rotating part is sleeved on the rotating rod through a sleeve hole 6 provided thereon, the rotating part has a cavity 8 for placing food 10 to be processed, and a through hole 9 connecting the cavity in the rotating part and the cavity in the barrel body is provided on the surface of the rotating part, the tool has a tool hole 46, the tool is arranged in the rotating part and is sleeved on the rotating rod in the rotating part through the tool hole, and the tool can be used to crush the food to be processed.

[0251] The rotating part can move along the vertical direction of the rotating rod as shown in the figure, and the rotating part can rotate under the drive of the rotating rod. Preferably, when the bottom of the rotating part is located at any position of the rotating rod above the lower section of the rotating rod, it can rotate under the drive of the rotating rod. It is further preferred that when the bottom of the rotating part is located at any position of the rotating rod above the lower section of the rotating rod, it can rotate synchronously under the drive of the rotating rod.

[0252] The lower section, middle section and upper section of the rotating rod refer to: the part of the rotating rod located in the barrel body is divided into twenty equal sections vertically, the first section close to the bottom of the barrel body is defined as the lower section of the rotating rod, the twentieth section is defined as the upper section of the rotating rod, and the remaining part between the lower section and the upper section of the rotating rod is the middle section of the rotating rod.

[0253] The above-mentioned limitation of "the lower section, middle section and upper section of the rotating rod" mainly describes the approximate position where the spinning action of the rotating part occurs. The purpose of rotating the rotating part in the present invention is to spin. The spinning effect is better when the rotating part is completely above the liquid surface in the barrel body, the spinning effect is poor when the rotating part is partially in the food liquid in the barrel body, and the spinning effect is the worst when the rotating part is completely in the food liquid in the barrel body.

[0254] The rotating rod is a hollow structure, in which an inner magnetic attraction portion 41 is arranged. The movement relationship between the inner magnetic attraction portion, the tool and the rotating portion along the vertical direction of the rotating rod is selected from any one of the following ⑴, ⑵ or ⑶:

[0255] ⑴ Tools such as Fig. 22 The outer magnetic attraction part 58 is shown, the inner magnetic attraction part moves vertically in the rotating rod and drives the tool to move vertically along the rotating rod through the magnetic force between the inner magnetic attraction part and the outer magnetic attraction part, and the vertical movement of the tool along the rotating rod can drive the rotating part to move vertically along the rotating rod; or,

[0256] (2) Rotating parts such as Fig.23 The shown one includes an outer magnetic attraction part, the inner magnetic attraction part moves vertically in the rotating rod and drives the rotating part to move vertically along the rotating rod through the magnetic force between the inner magnetic attraction part and the outer magnetic attraction part, and the vertical movement of the rotating part along the rotating rod can drive the tool to move vertically along the rotating rod; or,

[0257] ⑶ The tool and the rotating part both include an external magnetic part, and the internal magnetic part moves vertically inside the rotating rod and drives the tool and / or the rotating part to move vertically along the rotating rod through the magnetic force between the internal magnetic part and the external magnetic part.

[0258] The rotational relationship between the rotating rod and the tool is: the rotating rod can drive the tool to rotate, preferably the rotating rod drives the tool to rotate through the tool hole and / or the rotating rod drives the tool to rotate through the magnetic force between the inner magnetic attraction part and the outer magnetic attraction part.

[0259] There are two types of magnetic force: one is magnetic attraction, that is, the corresponding magnetic poles of the inner magnetic attraction part and the outer magnetic attraction part are opposite in magnetic properties, or one is an electromagnet or a permanent magnet and the other is a component made of ferromagnetic material. The attraction between the two magnetic poles, the attraction between the electromagnet and the ferromagnetic material, or the attraction between the permanent magnet and the ferromagnetic material forms the magnetic attraction between the inner magnetic attraction part and the outer magnetic attraction part.

[0260] The other is magnetic repulsion, that is, the magnetic poles corresponding to the inner magnetic attraction part and the outer magnetic attraction part have the same magnetic properties, and the repulsion between the two magnetic poles forms the magnetic repulsion between the inner magnetic attraction part and the outer magnetic attraction part.

[0261] The magnetic force between the inner magnetic part and the outer magnetic part in the above solution includes three modes: 1. There is only magnetic attraction between the inner magnetic part and the outer magnetic part; 2. There is only magnetic repulsion between the inner magnetic part and the outer magnetic part; 3. There is a combination of magnetic attraction and magnetic repulsion between the inner magnetic part and the outer magnetic part. In this case, the magnetic force can be any of the above three modes.

[0262] To facilitate understanding of the rotating rod in the present invention, the following explanation is given: the "knife shaft" in the existing food processor is equivalent to a part of the functions and effects of the rotating rod in the present invention. In existing food processors, the knife is generally fixed on the knife shaft and driven by the knife shaft to crush food. The functions of the rotating rod in the present invention are: 1. The knife is mounted on the rotating rod, and the rotating rod drives the knife to crush food; 2. The knife can move vertically along the rotating rod (rise or fall); 3. The rotating part is mounted on the rotating rod; 4. The rotating part moves vertically along the rotating rod (rise or fall); 5. The rotating part is driven by the rotating rod to rotate (to achieve spin drying).

[0263] The vertical direction is shown in the drawings: including the vertical direction and the direction inclined relative to the vertical direction, etc. The transverse direction is also shown in the drawings: including the horizontal direction and the direction inclined relative to the horizontal direction, etc. The longitudinal direction is shown in the drawings: indicating the direction perpendicular to the plane of the drawings and the direction inclined relative to the vertical direction, etc.

[0264] The power unit can be located in the base 18 below the barrel, or Fig.12 As shown, it is located above the barrel body. In the former structure, the lower end 37 of the barrel body is embedded in the upper end 38 of the base ( Fig.13 As shown), a rotation support structure 36 (bearing) is provided in the bottom plate 15 of the barrel body. The rotation support structure can be a ball bearing, a microporous oil-containing bearing or other types of bearings that can support high-speed rotation.

[0265] The rotating rod is partially located in the barrel body, which means that the rotating rod is a whole, which can be Figures 2 to 10 As shown, the end portion 12 below the lower section of the rotating rod is slidably sealed through the bottom of the barrel body and connected to a half coupling 14, which is connected to the half coupling 14 at the upper end portion of the output shaft to form a complete "coupling", and the output shaft of the power unit drives the rotating rod to rotate through the coupling.

[0266] The rotating rod can be a structure with the same outer diameter from top to bottom (such as Fig.11 , 12 , 13), or it can be Figures 2 to 10 The structure shown has a smaller outer diameter at the lower end portion, but of course a structure with a larger outer diameter at the lower end portion is also possible.

[0267] The rotating rod is completely located in the barrel, which means that the rotating rod is a whole and can be Fig.12 As shown, the power unit is arranged above or inside the barrel body, and a rotating rod is arranged below the power unit, and the rotating rod is located in the barrel body as a whole.

[0268] The structure of the above-mentioned inner magnetic attraction part and outer magnetic attraction part is: the inner magnetic attraction part is selected from any one, any two or all three of ferromagnetic material (such as iron parts), permanent magnet or electromagnet, and the outer magnetic attraction part is selected from any one, any two or all three of ferromagnetic material (such as iron parts), permanent magnet or electromagnet, and there is a magnetic force between the inner magnetic attraction part and the outer magnetic attraction part; or, at least a part of the inner magnetic attraction part is a part made of ferromagnetic material or at least a part is made of permanent magnet material, preferably, at least a part of the outer magnetic attraction part is a part made of ferromagnetic material or at least a part is made of permanent magnet material; or, when at least a part of the inner magnetic attraction part is a part made of ferromagnetic material, at least a part of the outer magnetic attraction part is a part made of permanent magnet material; or when at least a part of the inner magnetic attraction part is a part made of permanent magnet material, at least a part of the outer magnetic attraction part is a part made of ferromagnetic material; or when at least a part of the inner magnetic attraction part is a part made of permanent magnet material, at least a part of the outer magnetic attraction part is a part made of ferromagnetic material; or when at least a part of the inner magnetic attraction part is a part made of permanent magnet material, at least a part of the outer magnetic attraction part is a part made of permanent magnet material. Alternatively, the rotating rod is a closed hollow structure.

[0269] The structure of the outer magnetic attraction portion is selected from any one of (1), (2), (3), (4), (5), (6), (7), or (8):

[0270] (1) Part or all of the tool is made of ferromagnetic material and forms an outer magnetic attraction portion, and part or all of the inner magnetic attraction portion can interact with part or all of the magnetic force of the tool.

[0271] (2) The inner edge of the tool hole is provided with ferromagnetic material or permanent magnet or electromagnet to form an outer magnetic attraction part, and part or all of the inner magnetic attraction part can interact with the inner edge of the tool hole by magnetic force.

[0272] ⑶ The upper end surface or bottom surface of the tool is provided with ferromagnetic material or permanent magnet or electromagnet to form an external magnetic attraction part, and part or all of the internal magnetic attraction part can interact with the upper end surface or bottom surface of the tool by magnetic force.

[0273] (4) Part or all of the tool is made of permanent magnet material and forms an outer magnetic attraction part, and part or all of the inner magnetic attraction part can interact with part or all of the magnetic force of the tool.

[0274] ⑸ Part or all of the rotating part is made of ferromagnetic material and forms an external magnetic attraction part, and part or all of the internal magnetic attraction part can interact with part or all of the magnetic force of the rotating part.

[0275] (6) The inner edge of the sleeve hole of the rotating part is provided with ferromagnetic material or permanent magnet or electromagnet to form an external magnetic attraction part, and part or all of the internal magnetic attraction part can interact with the magnetic force of the inner edge of the rotating part.

[0278] No matter which type of external magnetic attraction part is selected, it is necessary to ensure that there is magnetic force between the internal magnetic attraction part and the external magnetic attraction part, for example: Fig. 22 As shown, the inner magnetic attraction part is entirely made of permanent magnets, the outer magnetic attraction part is embedded in the annular groove on the inner edge of the tool hole of the tool 7 and is made of permanent magnets, and the mutual magnetic attraction of the two permanent magnets enables the inner magnetic attraction part to drive the tool to rise and fall (vertical movement); for another example: the tool 7 is made of 400 series stainless steel with higher hardness, and the outer edge of the inner magnetic attraction part is embedded with a permanent magnet. The mutual magnetic attraction between the 400 series stainless steel and the permanent magnet enables the inner magnetic attraction part to drive the tool to rise and fall (vertical movement); for another example: Fig.23 As shown, a permanent magnet is embedded in the annular groove on the inner edge of the sleeve hole 6 at the bottom of the rotating part, and a permanent magnet is embedded in the annular groove on the outer edge of the inner magnetic attraction part. The mutual magnetic attraction of the two permanent magnets enables the inner magnetic attraction part to drive the rotating part to rise and fall (vertical movement).

Figure 2 A sleeve hole is provided at the bottom of the rotating part, and another sleeve hole can be provided on the upper cover, and the rotating rod passes through the two sleeve holes; if the opening is small and is located at the upper end of the rotating part close to the edge or side wall (similar to Fig. 9 The sleeve holes are arranged at the bottom of the rotating part and the upper end of the rotating part, and the rotating rod passes through the two sleeve holes.

[0302] The above-mentioned rotating part descends along the rotating rod under the action of gravity means that when the tool descends slowly, the rotating part descends under the action of gravity, rather than the tool supporting the rotating part to descend. The above-mentioned tool and rotating part descend along the rotating rod under the action of gravity means that when the inner magnetic attraction part does not drive the tool and / or the rotating part to descend through the magnetic force, the tool and the rotating part can descend under the action of gravity.

[0314] (5) When the upper end or side wall of the rotating part has an opening: the opening of the rotating part has an inwardly bent edge or bent ridge.

[0315] In this structure, if there is no upper cover at the opening, the sleeve hole is set at the bottom of the rotating part, and the rotating rod passes through the one sleeve hole and out of the opening; if the opening is small and located at the upper end of the rotating part close to the edge or side wall, the sleeve hole can also be set at the bottom of the rotating part and the bent edge, or the sleeve hole can be set at the bottom of the rotating part and the bent edge, and the rotating rod passes through the two sleeve holes.

[0319] ⑺When the upper end or side wall of the rotating part has an opening: the inner edge of the rotating part has an inward convex plate, a convex block or a convex ring, and the tool is provided with a clamping part that can clamp the bottom plate or the inner side wall of the rotating part.

[0321] The card installation part is Figure 8 The illustrated clamping portion only retains one clamping portion (upper label 34) located inside the rotating portion, but does not have another clamping portion (lower label 34) located below the rotating portion.

[0322] ⑻When the upper end or side wall of the rotating part has an opening:

[0323] The rotating part has a beam-shaped structure that closes a portion of the opening;

[0324] When the rotating part rises along the rotating rod, it can drive the tool to rise;

[0326] The beam-shaped structure can be a beam in a straight line, a cross, a triangle or the like located at the opening, and the upper end of the rotating part beside the beam is the opening.

[0327] The above-mentioned tool descends along the rotating rod under the action of gravity means that when the rotating part descends slowly, the tool descends under the action of gravity, rather than the rotating part supporting the rotating part to descend. The above-mentioned tool and the rotating part descend along the rotating rod under the action of gravity means that when the inner magnetic attraction part does not drive the tool and / or the rotating part to descend through the magnetic force, the tool and the rotating part can descend under the action of gravity.

[0328] There is a magnetic force between the inner magnetic attraction part and the outer magnetic attraction part, which can be realized in a variety of ways, which are described below. The rotating rod is preferably a hollow and closed structure, and its internal structure is selected from any one of ⑴, ⑵, ⑶, ⑷, ⑸, ⑹, ⑺, ⑻, ⑼ or ⑽:

[0329] (1) The driving part 36 and the telescopic part 42 are arranged in the rotating rod: Fig.14 As shown, the driving part is located at the lower end of the rotating rod, and the driving part drives the telescopic part above it to extend or retract. The extension or retraction of the telescopic part can drive the inner magnetic attraction part arranged thereon to rise or fall.

[0330] (2) A driving part and a telescopic part are arranged inside the rotating rod: the driving part is located at the upper end inside the rotating rod, and the driving part drives the telescopic part below it to extend or retract, and the extension or retraction of the telescopic part can drive the inner magnetic attraction part arranged thereon to descend or ascend.

[0331] ⑶ A driving part and a screw 43 are arranged inside the rotating rod: the driving part is located at the lower end inside the rotating rod, and the driving part drives the screw above it to rotate. The inner magnetic part is engaged and sleeved on the screw through the internal threaded hole arranged thereon, and the rotation of the screw can drive the inner magnetic part to rise or fall. The inner magnetic part is equivalent to the nut or a part of the inner magnetic part is equivalent to the nut.

[0332] ⑷ A driving part and a screw are arranged inside the rotating rod: Fig.17 As shown, the driving part is located at the upper end of the rotating rod, and the driving part drives the screw below it to rotate. The inner magnetic part is engaged and sleeved on the screw through the internal threaded hole provided thereon, and the rotation of the screw can drive the inner magnetic part to descend or ascend. The inner magnetic part is equivalent to the nut or a part of the inner magnetic part is equivalent to the nut.

[0333] ⑸ Set the screw vertically in the rotating rod: Fig.15 As shown, the inner magnetic part is meshed and sleeved on the screw through the internal threaded hole provided thereon. When the screw rotates with the rotating rod, the inner magnetic part rotates relative to the screw under the action of inertia force, and the relative rotation causes the inner magnetic part to rise or fall along the external thread of the screw. The inner magnetic part is equivalent to the nut or a part of the inner magnetic part is equivalent to the nut. The upper end or lower end of the screw is connected to the upper end or lower end of the rotating rod through the base 45. It is preferred that the screw is vertically fixed in the rotating rod, and it is preferred that the screw is vertically fixed in the rotating rod and the rotation axes of the two are the same.

[0334] ⑹ Set up an internal magnetic attraction part inside the rotating rod: Fig.16 As shown, the inner wall of the rotating rod has an internal thread vertically, and the axis of the internal thread is preferably the same as the rotation axis of the rotating rod, and the outer wall of the inner magnetic part has an external thread, and the internal thread and the external thread can mesh with each other; when the rotating rod rotates, the inner magnetic part rotates relative to the rotating rod under the action of inertia, and the relative rotation causes the inner magnetic part to rise or fall along the internal thread of the rotating rod. The inner magnetic part is equivalent to the nut or a part of the inner magnetic part is equivalent to the nut.

[0335] ⑺The telescopic part is set inside the rotating rod: Fig.13 As shown, the lower end of the rotating rod extends from the bottom plate of the barrel body to the bottom of the bottom plate, and the rotating rod is connected to the driving part housing arranged below the bottom plate of the barrel body. Only a telescopic part is arranged inside the rotating rod, and the lower end of the telescopic part is connected to the driving part. The lower end of the driving part is connected to the power unit through a coupling, and the power unit drives the driving part and the rotating rod to rotate. The driving part can also drive the telescopic part inside the rotating rod to extend or retract inside the rotating rod. When the telescopic part extends or retracts, it can drive the internal magnetic attraction part arranged at its upper end to rise or fall.

[0336] ⑻The rotating rod has a closed hollow structure, such as Fig.21As shown, the outer edge of the inner magnetic attraction part is closely fitted with the inner edge of the rotating rod, and the inner magnetic attraction part divides the rotating rod into two mutually isolated pressure chambers 50 and 52, and the top surface and bottom surface of the inner magnetic attraction part are respectively located in the two pressure chambers; the pump 56 can be arranged in any pressure chamber, or it can be arranged in any pressure chamber. Fig.21 The pump is shown as being arranged in a space separated by a partition 54 in the rotating rod, and the space is located outside the pressure chamber 52. The pump can also be arranged on the entire outer surface of the rotating rod. The two ports 55 and 53 of the pump are respectively connected to the two pressure chambers 50 and 52 directly or through a pipeline 51; when the pump inputs fluid into one pressure chamber 50, the inner magnetic attraction part can move toward the other pressure chamber 52, and when the pump inputs fluid into the other pressure chamber 52, the inner magnetic attraction part can move toward one pressure chamber 50.

[0337] ⑼ The rotating rod is a closed hollow structure, such as Fig. 22 As shown, the outer edge of the inner magnetic attraction part is closely fitted with the inner edge of the rotating rod, and the inner magnetic attraction part divides the rotating rod into two pressure chambers 50 and 52 isolated from each other. The top surface and the bottom surface of the inner magnetic attraction part are respectively located in the two pressure chambers, and the two pressure chambers are filled with gas;

[0338] The pump is arranged inside any pressure chamber, outside the pressure chamber, or in an air storage chamber 57 separated by a partition. One port 53 of the pump is connected to any pressure chamber directly or through a pipeline, and the other port 55 of the pump is connected to the air storage chamber directly or through a pipeline. When the pump transports the gas from the pressure chamber 52 connected to it to the air storage chamber, the inner magnetic attraction part can be moved toward the pressure chamber 52 connected to the pump. When the pump transports the gas from the air storage chamber to the pressure chamber 52 connected to the pump, the inner magnetic attraction part can be moved toward the pressure chamber 50 not connected to the pump.

[0339] ⑽ A driving part and a vertically arranged screw are arranged in the rotating rod:

[0340] The driving part and / or the inner magnetic part are mounted on the screw through the inner threaded hole provided thereon, and the inner magnetic part is arranged on the driving part. The driving part can drive itself to rotate relative to the screw, so that the driving part and the inner magnetic part rise or fall along the screw. For example, the driving part and the screw constitute a "through-type linear screw motor".

[0341] (11) A linear motor is vertically arranged inside the rotating rod, and the mover can move vertically along the stator. The inner magnetic attraction part is arranged on the mover, so that the mover and the inner magnetic attraction part can rise or fall.

[0342] The rotation of the tool is driven by the rotating rod, specifically by the external shape of the rotating rod, which is selected from any one of (1), (2), (3), (4), (5) or (6):

[0343] (1) Part or all of the outer edge of the rotating rod Figures 14 to 17As shown in 20, a key block 40 is provided, and a key groove 47 matching with the key block is provided on the tool or in the tool hole, and the rotating rod can drive the tool to rotate through the key block.

[0344] The key block can be arranged only on the outer edge of the lower section of the rotating rod, or on the outer edges of the lower section and the middle section of the rotating rod, or on the outer edges of the middle section and the upper section of the rotating rod, or on the outer edges of the upper section, the middle section and the lower section of the rotating rod. The first three represent that the key block is arranged partially in the vertical direction of the rotating rod, and the last one represents that the key block is arranged in the entire vertical direction of the rotating rod.

[0345] (2) A keyway is provided partially or completely on the outer edge of the rotating rod, and a key block matching the keyway is provided on the tool or in the tool hole, and the rotating rod can drive the tool to rotate through the keyway.

[0346] The key slot can be provided only on the outer edge of the lower section of the rotating rod, or on the outer edges of the lower section and the middle section of the rotating rod, or on the outer edges of the middle section and the upper section of the rotating rod, or on the outer edges of the upper section, the middle section, and the lower section of the rotating rod. The first three represent that the key slot is partially provided in the vertical direction of the rotating rod, and the last one represents that the key slot is fully provided in the vertical direction of the rotating rod.

[0347] ⑶ The shape of the transverse cross section of part or all of the rotating rod is as follows Fig.19 The tool hole can be the same as the transverse cross section of the rotating rod but slightly larger than the transverse cross section, for example Fig.19 In the embodiment, both are elliptical, but there is a clearance fit between the two, that is, there is a certain gap between the outer edge of the rotating rod and the inner edge of the tool hole, so that the tool can move along the rotating rod. Of course, the transverse cross-section of the rotating rod is a polygon, and the tool hole is the same but slightly larger polygon, or the transverse cross-section of the rotating rod is an ellipse, and the tool hole is a slightly larger polygon. In general, as long as the outer shape of the transverse cross-section of the rotating rod can collide or contact with the inner edge of the tool hole when rotating and drive the tool to rotate.

[0348] (4) The shape of the transverse cross section of part or all of the rotating rod is circular, and the tool is mounted on the rotating rod through the tool hole, and the rotating rod can drive the tool to rotate through the circle. In this structure, the tool hole can also be circular or polygonal, and the rotating rod can also drive the tool to rotate through friction contact and collision with the tool hole. For example Fig. 20 If the key block and keyway are removed, the transverse cross section is circular, and the tool hole 46 of the tool is also circular. Since the rotating rod rotates at a high speed, it can also drive the tool to rotate when it frictionally contacts and collides with the tool hole, but the tool rotation speed may be lower than the rotating rod rotation speed.

[0349] (5) The shape of the transverse cross section of part or all of the rotating rod is circular or non-circular, the tool is mounted on the rotating rod through the tool hole, and the rotating rod drives the tool to rotate through the magnetic force of the inner magnetic attraction part and the outer magnetic attraction part. In this structure, the external shape of the transverse cross section of the rotating rod and the shape of the tool hole do not necessarily match each other, but the tool is driven to rotate through the magnetic force.

[0350] (6) A rotation limit structure is provided on part or all of the outer edge of the rotating rod, and a rotation limit structure of a corresponding shape is provided on the tool or the tool hole, and the rotating rod can drive the tool to rotate through the rotation limit structure. For example: a toggle plate extending in the radial direction is provided on the rotating rod, and a baffle is provided on the tool, and the toggle plate can push the tool to rotate through the baffle when the rotating rod rotates.

[0351] Regardless of which of the above ⑴~⑹ the external shape of the rotating rod is selected, the rotating part and the tool must be able to rise or fall along the rotating rod.

[0352] The rotation of the cutter can occur at any position of the rotating rod. For example, a key block is set on the rotating rod, and a key slot is set on the cutter hole. In this case, the cutter can rotate under the drive of the rotating rod when it is lifted or lowered (moved vertically) along the rotating rod, so that the cutter can crush the food to be processed in the rotating part during the process of lifting or lowering (moving vertically) along the rotating rod. For example, a key block is set at the lower section of the rotating rod, and the cutter can be in a free rotation state when it is in the middle and upper sections of the rotating rod (the rotation speed of the cutter is not constant, and may be the same as the rotating rod, or lower than the rotating rod, or even zero), that is, the rotating rod can drive the cutter to rotate through friction contact, collision, etc. due to its high rotation speed, but the rotation speed of the cutter is lower than that of the rotating rod. When the cutter moves to the lower section of the rotating rod where the key block is set, the key block drives the cutter to rotate at a higher speed through the key slot.

[0353] The structure with a non-circular or circular transverse cross section may also be a structure with a lower section of the rotating rod of this shape. When the tool moves to the lower section, it rotates with the rotating rod, and the rotation speed is lower at other positions of the rotating rod.

[0354] In summary, for the rotation speed of the cutter, the preferred structure is: when the cutter is at the lower section of the rotating rod, it maintains the same rotation speed as the rotating rod (ie, the cutter is at the maximum crushing speed and the crushing effect is best).

[0355] In addition to the rotation of the tool, the rotating part is also rotated by the rotating rod, that is, the matching of the sleeve hole of the rotating part and the outer shape of the rotating rod can also be the same as the structure of the above-mentioned tools ⑴~⑹, that is, the tool is replaced by the rotating part, and the tool hole is replaced by the sleeve hole, which can be a sleeve hole at the bottom of the rotating part, or it can be the two sleeve holes that appear in the above-mentioned "the relationship between the rotating part and the tool when the external magnetic part is on the tool or on the rotating part ⑴~⑻". Of course, it is also possible for the sleeve hole of the rotating part and the rotating rod to be clearance-matched, but in order to achieve the separation of the residue and juice after the crushed food to be processed in the rotating part, it is necessary for the rotating part to maintain the same rotation speed as the rotating rod when it is in the middle and / or upper part of the rotating rod, and the rotation speed can be lower or the same at other positions.

[0356] Maintaining the same rotation speed means that the rotating part can first stay at a certain position on the rotating rod, then maintain the same rotation speed as the rotating rod, and then throw the juice in the residue juice out of the through hole into the barrel outside the rotating part. In order to achieve the position stay, the rotating part needs to maintain a height position on the rotating rod in the vertical direction, and its structure is selected from any one of (1), (2), (3), (4), (5), (6) or (7):

[0357] (1) The rotating part maintains a height position on the rotating rod through an embedded structure.

[0358] Embedded structure Figure 2 As shown, reference numeral 3 is a wedge-shaped component, and the wedge-shaped component can be as Fig.14 The engagement shown is connected to the protrusion on the upper end surface of the rotating rod, or as shown in Fig.16 The meshing connection shown is in the groove on the upper end face of the rotating rod. The transverse cross section of the wedge-shaped component can be circular, square or other shapes, and correspondingly, the sleeve hole provided in the rotating part (including the position made directly at the upper end of the rotating part, the upper cover at the opening, the crossbeam, the bent edge, the bottom of the rotating part, etc.) is the same as the wedge-shaped component but slightly smaller, that is, the sleeve hole and the outer edge of a certain part of the wedge-shaped component are interference fit. The wedge-shaped component is made of rubber or other materials. When the rotating part is driven by the tool or the inner magnetic attraction part and moves vertically to the wedge-shaped component, the wedge-shaped component is embedded in the sleeve hole, so that the rotating part is embedded there and keeps the same rotation speed as the rotating rod or the rotating part is in a free rotation state (the rotation speed of the rotating part is not constant, it may be the same as the rotating rod, it may be lower than the rotating rod, and even the rotation speed of the rotating part is zero).

[0359] The embedded structure can also be that the rotating rod has an upper section in a square, cylindrical or other shape, and a groove or protrusion can be set on its outer edge, and the sleeve hole is correspondingly provided with a protrusion or groove, for example: a groove is set on the rotating rod, and a protrusion is set on the inner edge of the sleeve hole. When the rotating part moves to the upper section, the protrusion is embedded in the groove, so that the rotating part is embedded there and keeps the same rotation speed as the rotating rod. If the rotating rod is higher, the groove or protrusion can also be set on the middle part of the rotating rod.

[0360] In addition to the above-mentioned sleeve hole that can be embedded through a wedge-shaped component, groove or protrusion, a structure that cooperates with the wedge-shaped component can be set at the upper end of the rotating part, or a protrusion or groove that is compatible with the groove or protrusion can be set. No matter where the embedded structure is set, the rotating part can maintain a height position on the rotating rod and maintain the same rotation speed as the rotating rod, or the rotating part can be in a free rotation state.

[0361] When the embedded structure is used, the rotating part can maintain the same rotation speed as the rotating rod during the process of rising along the rotating rod, or the rotating part can be in a free rotation state. When embedded, the preferred solution is that the rotating part and the rotating rod maintain the same rotation speed, but in actual use, the wedge-shaped component and the groove or protrusion structure may temporarily slip off, and at this time, the rotation speed of the rotating part may be slightly lower than that of the rotating rod.

[0362] (2) The rotating part maintains a height position on the rotating rod through a clamping structure.

[0363] The clamping structure means that a buckle claw or buckle groove is provided on the upper section of the rotating rod, and a corresponding buckle groove or buckle claw is provided at the sleeve hole of the rotating part or the upper end of the rotating part, and the buckle claw can be clamped into the buckle groove so that the rotating part maintains a height position at the upper section of the rotating rod.

[0364] The clamping structure can also be: a clamping plate or a clamping slot is provided on the upper section of the rotating rod, and a corresponding clamping slot or clamping plate is provided at the sleeve hole of the rotating part or at the upper end of the rotating part, and the clamping plate can be clamped into the clamping slot so that the rotating part maintains a height position at the upper section of the rotating rod.

[0365] When the clamping structure is used, the rotating part can maintain the same rotation speed as the rotating rod during the process of rising along the rotating rod, or the rotating part is in a free rotation state. After clamping, the rotating part and the rotating rod maintain the same rotation speed.

[0366] ⑶ The rotating part maintains a height position on the rotating rod through an engaging structure.

[0367] The meshing structure means that an external thread is provided on the upper section of the rotating rod, and a corresponding internal thread is provided at the sleeve hole of the rotating part or at the upper end of the rotating part. The external thread and the internal thread mesh with each other so that the rotating part maintains a height position at the upper section of the rotating rod.

[0368] When the meshing structure is used, the rotating part can maintain the same rotation speed as the rotating rod during the process of ascending along the rotating rod, or the rotating part is in a free rotation state. After meshing, the rotating part and the rotating rod maintain the same rotation speed.

[0369] (4) The magnetic force between the outer magnetic attraction part and the inner magnetic attraction part on the tool keeps the tool at a height position on the rotating rod, and the tool then keeps the rotating part at a height position on the rotating rod.

[0370] The structure is that the tool includes an external magnetic attraction part, and the rotating part keeps the same rotation speed as the rotating rod during the process of rising along the rotating rod, or the rotating part is in a free rotation state. When the height position is maintained, the rotating part and the rotating rod keep the same rotation speed or the rotating part is in a free rotation state.

[0371] (5) The rotating part maintains a height position on the rotating rod through the magnetic force of the outer magnetic attraction part and the inner magnetic attraction part.

[0372] The structure is that the rotating part includes an external magnetic attraction part, and the rotating part maintains the same rotation speed as the rotating rod during the process of rising along the rotating rod, or the rotating part is in a free rotation state. When the height position is maintained, the rotating part and the rotating rod maintain the same rotation speed or the rotating part is in a free rotation state.

[0373] (6) A ratchet structure or a barb structure is provided between the rotating part and the rotating rod, preferably a vertical ratchet structure or a vertical barb structure, which enables the rotating part to maintain a height position on the rotating rod.

[0374] Any one of the pawl and the ratchet of the ratchet structure can be set in the sleeve hole of the rotating part or the upper end of the rotating part, and the other can be set in the upper section of the rotating rod. The mutual cooperation between the pawl and the ratchet enables the rotating part to maintain a height position at the upper section of the rotating rod.

[0375] The barbs in the barb structure can be arranged on the upper section of the rotating rod. When the sleeve hole passes through the barbs vertically upward, the barbs enable the rotating part to maintain a height position on the rotating rod.

[0376] ⑺ A height-maintaining magnetic attraction part formed by a permanent magnet, an electromagnet or a ferromagnet is arranged in the middle or upper part of the rotating rod, and a permanent magnet, an electromagnet or a ferromagnet is arranged on the rotating part. When the rotating part approaches the height-maintaining magnetic attraction part on the rotating rod, the two attract each other so that the rotating part maintains a height position. In this structure, the preferred scheme is that at least one of the height-maintaining magnetic attraction part and the permanent magnet, electromagnet or ferromagnet on the rotating part adopts an electromagnet, and the mutual attraction between the rotating rod and the rotating part and the maintenance of the height position of the rotating part are achieved by turning the electromagnet on and off.

[0377] As mentioned above, after the cutter crushes the food to be processed, such as watermelon, pear, apple and other water-containing foods, juice will be produced, and the rotating part will be in a state of residue and juice mixed; for example, soybeans, coffee beans and other water-free or low-water foods will add water in the barrel, and the crushed residue in the rotating part will absorb water, which will also make the rotating part a state of residue and juice mixed. Regardless of the type of food to be processed, it is necessary to further drain the juice in the residue. The preferred solution is to lift the rotating part above the liquid level 59 in the barrel, and then rotate the rotating part to form a drying action, so that the juice in the residue is thrown out from the through hole when the rotating part rotates, and then the juice flows to the bottom of the barrel.

[0378] The above-mentioned height-maintaining position realizes the lifting of the rotating part above the liquid surface, and the spin-drying action is realized by the following structure, specifically: the structure in which the rotating rod drives the rotating part to rotate is selected from any one of ⑴, ⑵, ⑶, ⑷, ⑸ or ⑹:

[0379] ⑴ Such as Figure 8 , 9 , 10, 11, 12, 18, a tongue-and-groove structure is provided between the upper end, the lower end or at least one of the side walls of the rotating part and the middle part or the upper section of the rotating rod; the tongue-and-groove structure specifically comprises a plate-shaped or strip-shaped component provided on the upper section of the rotating rod, the surface of the component facing the rotating part is provided with a tongue-and-groove or a tenon, and the upper end surface of the rotating part ( Figure 8 )、The upper end of the rotating part ( Fig. 9 ), the upper cover surface ( Fig.12 ), bend edge surface( Fig.10 ) and the beam surface are provided with tenons or tenons. When the rotating part rises to the right position (the tool drives the rotating part to rise or the rotating part itself is attracted to rise by the internal magnetic attraction part), the tenons and tenons fit in with each other, so that the rotating part is connected with the rotating rod at this position, and the two maintain the same rotation speed, thereby realizing the drying action of the rotating part.

[0380] (2) At least one of an embedded structure, a clamping structure or an engaging structure is arranged between the upper end, the lower end or at least one of the side walls of the rotating part and the middle part or the upper section of the rotating rod.

[0381] In the relevant description of maintaining the height position, the embedded structure, the clamping structure and the meshing structure are mentioned. The three can not only keep the rotating part at the height position, but also keep the rotating part and the rotating rod at the same rotation speed or a slightly lower rotation speed, which will not be repeated here.

[0382] ⑶ A rotation limiting structure with a shape that matches the upper end, lower end or side wall of the rotating part is provided in the middle part or the upper section of the rotating rod.

[0383] The rotation limiting structure means that a cover for limiting can be set on the rotating rod, for example, a cover with a square interior is set on the upper section of the rotating rod, and the upper end of the rotating part can be made into a square or a square structure is set on the upper end of the rotating part. When the rotating part rises to this position, the upper end of the rotating part or the square structure is embedded in the square cover, thereby realizing the connection between the rotating part and the rotating rod, so that the rotating part and the rotating rod maintain the same rotation speed.

[0384] In addition, the rotation limiting structure may also be a frame with a certain shape inside, which can limit the rotation of the rotating part and achieve the same rotation speed of the rotating part and the rotating rod.

[0385] Furthermore, the rotation limiting structure can also be able to limit the rotating part, but the rotation speed is different. For example: the interior of the rotation limiting structure is a hexagon, the upper end of the rotating part is a quadrilateral, or a quadrilateral structure is provided on the upper end of the rotating part. The hexagon can limit the quadrilateral, but the rotation speed of the rotating part may be slightly lower than that of the rotating rod.

[0386] (4) The shape of the sleeve hole of the rotating part matches the shape of at least one part of the rotating rod, and the rotating rod drives the rotating part to rotate.

[0387] In this structure, the sleeve hole is, for example, square, and the transverse cross-section of the middle and / or upper section of the rotating rod is also square. When the rotating part rises to the square position, the rotating part maintains the height position, and the sleeve hole cooperates with the transverse cross-section of the rotating rod, and the rotating part and the rotating rod maintain the same rotation speed.

[0388] For another example: the sleeve hole is square, and the transverse cross-section of the middle and / or upper section of the rotating rod is circular. When the rotating part rises to the circular position, the rotating part maintains the height position, and the inner edge of the sleeve hole is subjected to friction contact and collision with the outer edge of the rotating rod, and the rotation speed of the rotating part is lower than the rotation speed of the rotating rod.

[0389] (5) The rotating rod drives the rotating part to rotate through the magnetic force of the inner magnetic attraction part and the outer magnetic attraction part.

[0390] In this structure, the inner magnetic attraction part and the outer magnetic attraction part are preferably permanent magnets, so that the magnetic force between the two is maximized. However, due to the fast rotation speed of the rotating rod, the magnetic force may be "off-target (temporary or intermittent)", that is, the temporary magnetic force is reduced, which will cause the rotation speed of the rotating part to decrease instantaneously. Therefore, the rotating part and the rotating rod can maintain the same rotation speed or the rotating part can be in a free rotation state.

[0391] (6) The rotating rod drives the tool to rotate, the rotating part is connected to the tool, and the rotating part and the tool rotate synchronously.

[0392] In this structure, the rotating part and the tool are connected to each other, the two rise or fall together, and the two rotate together.

[0393] The above mentioned preferred solution for the cutter at the lower section of the rotating rod is to maintain the same rotation speed as the rotating rod, that is, to crush the food to be processed inside the rotating part at the maximum rotation speed. At this time, the motion state of the rotating part is divided into multiple situations, including: 1. The rotating part and the rotating rod maintain the same rotation speed; 2. The rotating part has a lower rotation speed than the rotating rod; 3. The rotating part remains stationary. Among them, the second and third states are preferred, and the third state is more preferred. At this time, the cutter is at the maximum rotation speed, and the rotating part remains stationary. At this time, the crushing effect and crushing efficiency of the food to be processed are the best, and the realization of the first, second, and third motion states is achieved by the following structure:

[0394] When the rotating part moves to the lower end of the barrel, it is limited by the rotation limiting structure ( Figure 2 , 3 , 4, 6, 7, 8, 9, 10, 11, 12) or in free rotation ( Figure 5 , 13 ), the rotation limiting structure is selected from any one of ⑴, ⑵, ⑶, ⑷ or ⑸:

[0395] (1) An insertion structure or a clamping structure is arranged between the bottom of the barrel body or at least one of the side walls at the lower end of the barrel body and the bottom of the rotating part.

[0396] Insert structure such as Fig.10 As shown, a boss 13 may be provided at the bottom of the barrel or the side wall of the lower end of the barrel, a tenon or a tenon may be provided on the boss or directly at the bottom of the barrel, and a tenon or a tenon at a corresponding position is provided at the bottom of the rotating part. When the rotating part descends to this position, the tenon and the tenon fit each other, thereby limiting the rotating part so that it remains stationary or can only shake within a small range. When the rotating part rises, the tenon and the tenon disengage, and the limit of the rotating part is released.

[0397] Card-mounted structure Figure 2 , 3 As shown in , 4, 6, 7, 8, 9, 11, and 12, the above-mentioned boss is directly provided with a protruding rod or a protruding plate 24 at the bottom of the barrel, and another protruding rod or a protruding plate 23 is provided at the bottom of the rotating part. When the rotating part descends to this position, the protruding rods or protruding plates block each other, thereby limiting the rotating part so that it remains stationary or can only shake within a small range. When the rotating part rises, the protruding rods or protruding plates are disengaged from each other, and the limit of the rotating part is released.

[0398] Shaking in a small range means that since the juice in the barrel is in a state of severe disturbance, the rotating part may be affected and shake.

[0399] (2) An insertion structure or a clamping structure is arranged between at least one of the bottom of the barrel body or the side wall of the lower end of the barrel body and the side wall of the rotating part.

[0400] In this structure, what is different from item (1) is that the side wall of the rotating part is provided with a mortise or tenon in the insertion structure and a protruding rod or protruding plate in the clamping structure, and the rest is the same as item (1).

[0401] ⑶ An engaging structure is arranged between the bottom of the barrel body or at least one of the side walls at the lower end of the barrel body and the bottom of the rotating part.

[0402] The structure is as Figure 4 As shown, a sleeve 27 with an external thread on the upper end is provided at the bottom of the barrel or the side wall of the lower end of the barrel, and a structure with an internal thread is provided at the bottom of the rotating part or the sleeve hole at the bottom of the rotating part is provided with an internal thread. When the rotating part descends to this position, the external thread and the internal thread are meshed and connected, so that the rotating part is limited. When the cutter rotates in the opposite direction, it gives a push to the rotating part to rotate in the opposite direction through the rotation of the food liquid in the barrel, and the rotating rod also gives a push to the rotating part to rotate in the opposite direction through friction contact and collision during reverse rotation, so that the internal thread of the rotating part is disengaged from the external thread. When all are disengaged, the rotating part starts to rise.

[0403] The engagement and disengagement can also be achieved in the following manner: during the descent of the rotating part and the rotating rod, the rotating part maintains the same rotation speed as the rotating rod or is in a free rotation state. The rotating part descends along the rotating rod as the rotating rod rotates, and then the internal thread and the external thread are engaged and connected. When the rotating part needs to rise, the rotating rod rotates in the opposite direction, and the rotating part rotates with the rotating rod to disengage the internal thread and the external thread. When all are disengaged, the rotating part rises along the rotating rod.

[0404] Of course, the internal threads and external threads mentioned above can be interchanged, for example: a sleeve with internal threads is provided at the bottom of the barrel body, and a structure with external threads is provided at the bottom of the rotating part, and the two can also be meshed and connected.

[0405] (4) An engaging structure is provided between at least one of the bottom of the barrel body or the side wall of the lower end of the barrel body and the side wall of the rotating part.

[0406] In this structure, the difference from item (3) is that: Figure 3 As shown, the side wall of the rotating part is provided with an external thread 26, which is meshed with the internal thread provided by the annular structure or the intermittent ridge structure 25 arranged in the barrel body, thereby limiting the rotating part. Of course, the internal thread can be directly provided on the side wall surface of the lower end of the barrel body.

[0407] The rest is the same as item (3).

[0408] ⑸ The inner side wall at the lower end of the barrel body is in a shape that is adapted to the lower end of the side wall of the rotating part, and this shape can block the rotation of the rotating part.

[0409] The structure is as Figure 6As shown, the inner wall of the lower end of the barrel is square, and the outer shape of the lower end of the rotating part is also square. When the rotating part descends, the two square shapes limit each other, so that the rotating part remains stationary. Of course, the square shape of the lower end of the barrel can be slightly larger, and the rotating part will not rotate in a large range, but can only shake in a small range. Of course, the inner wall of the lower end of the barrel is hexagonal, and the outer shape of the lower end of the rotating part is quadrilateral, as long as the hexagon can block the limiting quadrilateral.

[0410] like Fig.15 , 16 As shown, the inner magnetic attraction part is located in the closed hollow structure rotating rod, and the rotating rod is divided into at least two spaces along the vertical direction (for example, there is only one inner magnetic attraction part and the space inside the rotating rod is divided into space A and space B). The positive effects are:

[0411] When there is fluid (liquid or gas) in the space inside the rotating rod, different spaces (for example, between space A and space B) have an interconnected structure 61 (for example, there is a gap or channel between the inner magnetic part and the inner wall of the rotating rod). When the inner magnetic part moves vertically inside the rotating rod, the connecting structure can enable the fluid in different spaces inside the rotating rod to flow (for example, the inner magnetic part moves from the direction of space A to the direction of space B, making space A larger and space B smaller. At the same time, the fluid in space B flows to space A through the connecting structure 61).

[0412] Therefore, even when the inner magnetic part moves vertically at high speed in the rotating rod and approaches the end, the inner magnetic part squeezes the fluid in the space in the vertical movement direction of the inner magnetic part (for example, space B) like a "piston", so that the fluid in this part of the space flows to space A through the connecting structure, thereby buffering the vertical movement of the inner magnetic part (damping effect or air spring effect).

[0413] "Dapping effect (for example, the fluid is liquid, which is incompressible, but under the squeezing effect of the moving inner magnetic part, the liquid will flow from the space with high pressure inside the rotating rod to the space with low pressure, and this flow process is also a damping process)" or "air spring" effect (for example, the fluid is air. At this time, there are both damping and air spring effects). This can prevent the inner magnetic part from impacting the inner end of the rotating rod at high speed and causing damage to components, prevent the inner magnetic part from being locked on the screw, and prevent the inner magnetic part from violently impacting the inner end of the rotating rod when it moves vertically at high speed to cause vibration of the entire machine, while also reducing noise.

[0414] or,

[0415] When there is gas in the space inside the rotating rod, different spaces are isolated from each other (for example, between space A and space B). When the inner magnetic part moves vertically inside the rotating rod (for example, the inner magnetic part moves from the direction of space A to the direction of space B, making space A larger and space B smaller), the inner magnetic part compresses the gas in space B, and buffers the vertical movement of the inner magnetic part inside the rotating rod. At this time, the gas has both a damping effect and an air spring effect. It can prevent the inner magnetic part from impacting the inner end of the rotating rod at high speed to cause damage to parts, prevent the inner magnetic part from being locked on the screw, and prevent the inner magnetic part from violently impacting the inner end of the rotating rod when it moves vertically at high speed to cause vibration of the entire machine, while also reducing noise.

[0416] Example 1

[0417] In this embodiment, Figure 2 As shown, the barrel body 5 is provided with an end cover 2, and a rotating rod 4 is provided in the barrel body. The rotating rod is partially located in the barrel body, and a sliding seal below the lower section of the rotating rod passes through the bottom of the barrel body. A half coupling 14 is provided at the end portion 12 below the lower section of the rotating rod and is connected to the half coupling 14 provided at the upper end portion of the output shaft. The power unit 17 drives the rotating rod to rotate through the coupling formed by the two half couplings 14.

[0418] The rotating part 21 is cylindrical in shape, and an upper cover 20 is provided at the upper opening. The upper cover can be provided on the rotating part by threaded connection or by snap-fitting. A sleeve hole 6 is provided at the bottom of the rotating part and the upper cover respectively, and both sleeve holes are sleeved on the rotating rod. A through hole 9 is provided on the surface of the rotating part and / or the upper cover to connect the interior of the rotating part and the barrel cavity 19, and the food to be processed 10 is placed in the cavity 8 inside the rotating part. The inner edge of the sleeve hole is circular and a certain gap is reserved between it and the outer edge of the rotating rod.

[0419] The tool hole sleeve of the tool is arranged on the rotating rod inside the rotating part, and a blade 11 is arranged on the outer edge of the tool. Since the tool contacts the rotating part when rising or falling, wear-resistant parts 22 are arranged on the upper end surface and bottom surface of the tool, such as food-grade rubber or food-grade stainless steel, etc., the purpose of which is to reduce the contact area between the tool and the internal surface of the rotating part.

[0420] A wedge-shaped component is provided at the upper end of the rotating rod, which is used to realize the height position of the rotating part and the spin-drying function. The wedge-shaped component is made of food-grade rubber materials, etc. The inner diameter of the sleeve hole located in the upper cover is smaller than the outer diameter of a certain height position of the wedge-shaped component. When the rotating part rises to this position, the sleeve hole is embedded in this position, so that the rotating part and the rotating rod maintain the same rotation speed. The wedge-shaped component can be detachable, for example: its lower end has an external thread, and the upper end surface of the rotating rod is provided with a recess with an internal thread, and the lower end of the wedge-shaped component is meshed and connected with the recess.

[0421] Two protruding plates 24 are arranged at the bottom of the barrel body, and another two protruding plates 23 are arranged at the bottom of the rotating part. When the rotating part descends to this position, the protruding plates block each other as shown in the figure, thereby realizing the rotation limit of the rotating part.

[0422] The protruding plate 24 also supports the rotating part in the vertical direction, so that it cannot continue to fall, and plays a role in limiting the vertical position of the rotating part. In this way, when the rotating part is located at or close to the bottom position of the barrel body, it is limited in both the vertical direction and the rotation direction, so that the rotating part in the preferred solution is in a stationary state or a small range of shaking.

[0423] The internal structure of the rotating rod is as follows Fig.14 As shown, the rotating rod is a hollow and closed structure (the rotating rod can be an integrated closed structure, or it can be realized by having a detachable sealing cover at the upper end, or it can be realized by installing a wedge-shaped component), and a driving part and a telescopic part are arranged in the cavity 39 inside the rotating rod, the driving part is located at the bottom in the figure, and the telescopic part is located at the top in the figure, and the driving part can drive the telescopic part to rise or fall. The internal magnetic attraction part is a permanent magnet as a whole, and an annular permanent magnet is embedded in the inner edge of the tool hole of the tool, and the permanent magnets at the two locations attract each other magnetically.

[0424] The external structure of the rotating rod is as follows Fig.14 As shown, a vertical long key block 40 is provided on the rotating rod, and the long key block extends from the lower section of the rotating rod to the upper section of the rotating rod. A key groove 47 ( Fig. 20 ).

[0425] The working process of this embodiment is:

[0426] 1. Open the end cover of the barrel, remove the wedge-shaped part, and put the watermelon in the rotating part.

[0427] 2. Install the rotating part on the rotating rod through the sleeve hole, then install the tool on the rotating rod (inside the rotating part) through the tool hole, then install the upper cover of the rotating part and the end cover.

[0428] 3. As the tool is attracted by the inner magnetic part, the tool stops on the rotating rod, and the rotating part is blocked by the tool and stops on the rotating rod. The power unit and the driving part are started, and the power unit drives the rotating rod to rotate. The rotating rod drives the tool to rotate (clockwise or counterclockwise) through the cooperation of the long key block and the keyway and the magnetic attraction between the inner magnetic part and the outer magnetic part. The driving part drives the inner magnetic part to descend through the telescopic part, and the inner magnetic part drives the tool to descend through magnetic attraction. When the tool descends, it supports the rotating part to descend.

[0429] The cutter rotates while descending, and the two sleeve holes of the rotating part are circular, and it also rotates under the friction contact of the rotating rod and the long key block. In addition, the rotation of the cutter will also drive the food to be processed to rotate, and also has a certain driving effect on the rotating part. Therefore, during the descent process, the rotating part and the rotating rod maintain the same rotation speed or the rotating part is in a free rotation state.

[0430] 4. When the rotating part descends to the lower end of the barrel body, the protruding plates block each other to keep the rotating part stationary, and when the inner magnetic part descends to the lowest point, the cutter also stops at this (height) position and maintains the same rotation speed as the rotating rod, thereby completely crushing the watermelon. When the timed crushing is over, the cutter can stop rotating or continue rotating, and the telescopic part rises and drives the cutter to rise through the inner magnetic part. The rotating part rises driven by the cutter (the cutter can be in a stopped state or a clockwise rotating state or a counterclockwise rotating state during the rising process). After the rotating part rises, the protruding plates can no longer restrict its rotation, so the rotating part also rotates.

[0431] 5. When the cutter makes the rotating part rise to the wedge-shaped part, the sleeve hole on the upper cover is embedded in a certain height position of the outer edge of the wedge-shaped part, and the rotating part maintains the height position and the same rotation speed as the rotating rod (it is possible that the rotating part is not tightly embedded in the wedge-shaped part and the rotating part is in a free rotation state), thereby throwing out the juice in the rotating part (through the through hole on the surface of the rotating part connecting the cavity in the rotating part and the cavity in the barrel body), and the watermelon residue is left in the rotating part.

[0432] 6. After a period of time, the rotating part stops rotating, open the end cover, remove the wedge-shaped part, and then remove the rotating part (the knife can be removed together), pour out the juice in the barrel and drink it.

[0433] Based on the structure of Example 1, some detailed structures are adjusted as follows:

[0434] A cylindrical component is arranged at the upper end of the rotating rod, so as to realize the height position keeping of the rotating part and the spin-drying function.

[0435] A permanent magnet (i.e., a height-maintaining magnetic attraction portion) is provided inside the cylindrical component, and the upper cover 20 is a component made of ferromagnetic material. When the rotating part rises to the position of the height-maintaining magnetic attraction portion, the sleeve hole is located there, and magnetic attraction is generated between the permanent magnet of the height-maintaining magnetic attraction portion and the upper cover made of ferromagnetic material, so that the rotating part maintains a height position, and the rotating part rotates as the rotating rod rotates.

[0436] The inner magnetic attraction part is a permanent magnet as a whole, and an annular permanent magnet is embedded in the inner edge of the tool hole of the tool. The corresponding magnetic poles of the two permanent magnets have the same magnetic properties, and the repulsion between the two magnetic poles forms the magnetic repulsion between the inner magnetic attraction part and the outer magnetic attraction part.

[0437] The working process is:

[0438] 1. Open the end cover of the barrel, remove the cylindrical parts, and put the watermelon in the rotating part.

[0439] 2. Install the rotating part on the rotating rod through the sleeve hole, and then install the tool on the rotating rod (inside the rotating part) through the tool hole (the horizontal height of the tool is higher than the height of the inner magnetic part in the rotating rod), and then install the upper cover of the rotating part and the end cover.

[0440] 3. As the tool is repelled by the magnetic force of the inner magnetic part, the tool stops on the rotating rod (the position is higher than the inner magnetic part), and the rotating part is blocked by the tool and stops on the rotating rod. The power unit and the drive unit are started, and the power unit drives the rotating rod to rotate. The rotating rod drives the tool to rotate (clockwise or counterclockwise) through the cooperation of the long key block and the keyway. The drive unit drives the inner magnetic part to descend through the telescopic part. After the inner magnetic part descends, the tool and the rotating part also descend under the action of gravity. However, the horizontal height of the tool is higher than the inner magnetic part.

[0441] The cutter rotates while descending, and the two sleeve holes of the rotating part are circular, and it also rotates under the friction contact of the rotating rod and the long key block. In addition, the rotation of the cutter will also drive the food to be processed to rotate, and also has a certain driving effect on the rotating part. Therefore, during the descent process, the rotating part and the rotating rod maintain the same rotation speed or the rotating part is in a free rotation state.

[0442] 4. When the rotating part descends to the lower end of the barrel body, the protruding plates block each other to keep the rotating part stationary, and when the inner magnetic part descends to the lowest point, the cutter also stops at this (height) position and maintains the same rotation speed as the rotating rod, thereby completely crushing the watermelon. When the timed crushing is over, the cutter can stop rotating or continue rotating, and the telescopic part rises, and the cutter is pushed up by the magnetic repulsion between the inner magnetic part and the cutter. The rotating part rises driven by the cutter (the cutter can be in a stopped state or a clockwise or counterclockwise rotation state during the rising process). After the rotating part rises, the protruding plate can no longer restrict its rotation, so the rotating part also rotates.

[0443] 5. When the cutter makes the rotating part rise to the cylindrical part, there is magnetic attraction between the height-maintaining magnetic part and the upper cover composed of ferromagnetic material, and the rotating part maintains its height position and rotates with the rotation of the rotating rod, thereby throwing out the juice in the rotating part (through the through hole on the surface of the rotating part connecting the cavity in the rotating part and the cavity in the barrel body), and the watermelon residue is left in the rotating part.

[0444] 6. After a period of time, the rotating part stops rotating, open the end cover, remove the cylindrical part, and then remove the rotating part (the cutter can be removed together), pour out the juice in the barrel and drink it.

[0445] Another example of structural adjustment: the permanent magnet provided in the above-mentioned cylindrical component can also be replaced by an electromagnet, and the upper cover 20 is a component composed of a permanent magnet (the relative magnetic poles of the electromagnet and the permanent magnet are opposite). When the upper cover of the rotating part rises above the height maintaining magnetic attraction part, the electromagnet of the height maintaining magnetic attraction part is energized and the upper cover composed of the permanent magnet is maintained above the height maintaining magnetic attraction part under the action of magnetic repulsion.

[0446] Example 2

[0447] In this embodiment, Figure 3 As shown, the difference from Example 1 is that:

[0448] 1. An annular structure 25 is provided on the lower end side wall inside the barrel body, an internal thread is provided on the inner edge of the annular structure, and an external thread is provided on the lower end side wall outside the rotating part. When the rotating part descends to this position, the external thread and the internal thread engage with each other (forming a rotation limiting structure), and the rotating part is limited.

[0449] 2. The internal structure of the rotating rod is as follows Fig.15 As shown, a screw is vertically arranged at the inner axis position of the rotating rod (the axis of the rotating rod refers to the axis of rotation of the rotating rod. The vertical arrangement of the screw at the inner axis position of the rotating rod means that the axis of the rotating rod is the same as the axis of rotation of the screw. When the axes of the two are the same, the technical effect is best, but when the axes are slightly different, the technical effect can also be achieved poorly or partially), the inner magnetic attraction part is meshed and sleeved on the screw through the internal threaded hole provided thereon, and when the screw rotates with the rotating rod (preferably, the screw is fixedly arranged in the rotating rod. When the screw is fixedly arranged in the rotating rod, the two rotate synchronously, and the technical effect is best. However, when the screw is not fixedly arranged, for example, the screw can rotate freely in the rotating rod, the technical effect can also be achieved poorly or partially), the inner magnetic attraction part rotates relative to the screw under the action of inertia force, and the relative rotation causes the inner magnetic attraction part to rise or fall along the external thread of the screw.

[0450] 3. The structure outside the rotating rod is as follows Fig.15 As shown, the long key block on the rotating rod is only arranged at the lower section and the middle section of the rotating rod. When the tool is driven by the internal magnetic attraction part to descend to the middle section and the lower section of the rotating rod, the sleeve hole of the rotating part is larger and can accommodate the rotating rod and the long key block thereon. The rotating part is in a free rotation state. When the tool rises to the upper section of the rotating rod, the tool is driven by the magnetic attraction and the friction contact of the rotating rod. The tool can maintain the same rotation speed as the rotating rod or the tool is in a free rotation state.

[0451] 4. The cutter rotates clockwise or counterclockwise as it descends along the rotating rod. The rotating part engages with a limiter after it descends. When the crushing is completed, the rotating rod rotates in the opposite direction, and the cutter also rotates in the opposite direction. The stirring of the juice and the frictional contact and collision of the rotating rod with the sleeve hole cause the rotating part to rotate in the opposite direction, thereby disengaging the rotating part from the internal thread.

[0452] Lubricating oil can be applied to the outer edge of the screw, and since the rotating rod is hollow and closed, the lubricating oil will not leak.

[0453] At the same time, there is air inside the rotating rod.

[0454] In addition, the barrel volume of a general household food processor is usually 1 to 4 liters, and the length of the rotating rod is generally only 0.1 to 0.3 meters. When the rotating rod speed is 200 to 600 rpm and the pitch of the screw outer thread is 2 mm, the vertical movement linear speed of the inner magnetic attraction part is 0.4 to 1.2 m / s. In less than one second, the inner magnetic attraction part can move from one end of the rotating rod to the other end.

[0455] The inner magnetic part is similar to a "piston" inside the rotating rod. When it moves at high speed and approaches the inner end of the rotating rod, it squeezes the air between the inner magnetic part and the end, compressing the air to act as an "air spring", greatly reducing the force of the inner magnetic part moving vertically at high speed to hit the inner end of the rotating rod, which can prevent damage to components at the inner end of the rotating rod, prevent the inner magnetic part from being locked on the screw, and reduce noise at the same time.

[0456] The outer edge of the inner magnetic part can be tightly fitted to the inner edge of the rotating rod, or the inner magnetic part is tightly fitted to the rotating rod and there is a connecting structure 61 between the two end faces of the inner magnetic part (for example, the inner magnetic part is tightly fitted to the rotating rod and the outer edge of the inner magnetic part has a through groove connecting the two end faces, or there is a gap between the inner magnetic part and the rotating rod, etc.). The connecting structure serves as a leakage channel between the air in the cavities in the rotating rods on both sides of the inner magnetic part. The preferred solution is: there is a gap between the inner magnetic part and the rotating rod, and when the inner magnetic part moves rapidly to one side, the compressed air can enter the cavity of the rotating rod on the other side through the leakage channel.

[0457] The rest is the same as Example 1.

[0458] Example 3

[0459] In this embodiment, Figure 4 As shown, the difference from Example 1 is that:

[0460] A sleeve 27 with an external thread on the upper end is provided at the bottom of the barrel body, and an internal thread is provided at the sleeve hole at the bottom of the rotating part. When the cutter rotates clockwise and drives the rotating part to descend to that position, the external thread and the internal thread are meshed and connected, so that the rotating part is limited. After the crushing is completed, (the power unit drives the rotating rod to rotate counterclockwise) when the cutter rotates counterclockwise, it gives a push to the rotating part to rotate in the opposite direction through the disturbance of the juice in the barrel body, and the rotating rod also gives a push to the rotating part to rotate in the opposite direction through friction contact and collision during reverse rotation, so that the internal thread of the rotating part is disengaged from the external thread. When all are disengaged, the rotating part begins to rise.

[0461] The rest is the same as Example 1.

[0462] Example 4

[0463] In this embodiment, Figure 5 As shown, it is different from Example 1 in that:

[0464] 1. The upper cover of the rotating part and the two sleeve holes at the bottom of the rotating part are both circular in shape, and the transverse cross section of the rotating rod 4 is as follows: Fig.19 The oval shown is a slightly smaller oval, and the tool hole 46 is an oval with a slightly larger area. The slightly smaller oval and the slightly larger oval cooperate with each other and drive the tool to rotate.

[0465] 2. Since the circular area of ​​the sleeve hole is relatively large, the rotating part is in a free rotation state when it is sleeved on the rotating rod, that is, the slightly smaller ellipse of the rotating rod can drive the rotating part to rotate through friction contact and collision, but the rotation speed may be the same as or slightly lower than that of the rotating rod, that is, after the rotating part leaves the wedge-shaped component, it is in a free rotation state during its descent, when it descends to the lowest position, and during its ascent.

[0466] 3. Whether the tool rotates clockwise or counterclockwise, it can lift the rotating part upward when it rises.

[0467] The rest is the same as Example 1.

[0468] Example 5

[0469] In this embodiment, Figure 6 As shown, it is different from Example 1 in that:

[0470] 1. The opening at the upper end of the rotating part is small and located at the edge of the upper end of the rotating part. The sleeve holes are arranged at the bottom and the upper end of the rotating part. The rotating rod passes through the two sleeve holes, and the upper cover is only used to put the food to be processed when it is opened or to close the opening when it is closed.

[0471] 2. The inner wall of the lower end of the barrel body is shaped to block the outer shape of the lower end of the limited rotating part. For example, the inner wall of the lower end of the barrel body is square, and the outer shape of the lower end of the rotating part is also square. When the rotating part descends, the two square shapes limit each other to keep the rotating part still. Of course, the square shape of the lower end of the barrel body can be slightly larger. The rotating part will not rotate in a large range and can only shake in a small range.

[0472] 3. Whether the cutter rotates clockwise or counterclockwise, it can push up the rotating part when it rises, so that it disengages from the inner wall of the lower end of the barrel and continues to rise.

[0473] The rest is the same as Example 1.

[0474] Example 6

[0475] In this embodiment, Figure 7 As shown, it is different from Example 1 in that:

[0476] 1. The internal structure of the rotating rod is as follows Fig.16 As shown, the inner wall of the rotating rod has an internal thread vertically, the axis of the internal thread is the same as the rotation axis of the rotating rod, the outer wall of the inner magnetic part has an external thread, and the internal thread and the external thread can engage with each other; when the rotating rod rotates, the inner magnetic part rotates relative to the rotating rod under the action of inertia force, and the relative rotation causes the inner magnetic part to rise or fall along the internal thread of the rotating rod.

[0477] 2. The structure outside the rotating rod is as follows Fig.16 As shown, the transverse cross-section of the upper and middle parts of the rotating rod is circular and the transverse cross-section of the lower part is hexagonal, and the inner edge of the tool hole of the tool is hexagonal. When the tool is located at the part where the transverse cross-section of the rotating rod is hexagonal, the transverse cross-section of the rotating rod cooperates with the two hexagons of the tool hole, so that the rotating rod drives the tool to rotate. When the tool is located at the part where the transverse cross-section of the rotating rod is circular, the rotating rod can drive the tool to rotate through friction contact and collision. At this time, the tool is in a free rotation state, that is, the tool may maintain the same rotation speed as the rotating rod or a lower rotation speed than the rotating rod.

[0478] 3. The rotating rod is filled with oil. The inner magnetic part is like a "piston" in the rotating rod. When it moves at high speed close to the inner end of the rotating rod, it squeezes the oil between the inner magnetic part and the end. The oil flows through the gap between the outer thread of the inner magnetic part and the inner thread of the inner edge of the rotating rod (the gap is a connected structure) or the through groove on the outer edge of the inner magnetic part (the through groove is a connected structure). That is, the gap and the through groove serve as leakage channels between the oil in the cavities of the rotating rod on both sides of the inner magnetic part. When the inner magnetic part moves rapidly to one side, the oil can enter the cavity of the rotating rod on the other side through the leakage channel. This process also plays a damping role.

[0479] 4. Whether the cutter rotates clockwise or counterclockwise, it can push up the rotating part when it rises, so that it disengages from the bottom of the barrel and continues to rise.

[0480] The rest is the same as Example 1.

[0483] 1. The upper opening of the rotating part is as follows Figure 8 As shown, no upper cover is provided at the opening, a sleeve hole is provided at the bottom of the rotating part, and the rotating rod passes through the sleeve hole and comes out from the opening.

[0484] 2. The tool is connected with two clamping parts 34 located inside and below the rotating part. The two clamping parts are arranged at the upper and lower ends of the outer edge of the sleeve 33 arranged below the tool, or can be directly arranged at the bottom or side wall of the tool through a bent structure. The two clamping parts can respectively support the rotating part to rise or hold the rotating part down when the tool rises or falls.

[0485] 3. A plate-shaped component 29 is provided on the upper section of the rotating rod, and a tenon 30 is provided on the surface of the component facing the rotating part, and a tenon 31 is provided on the upper end surface of the rotating part opposite to the tenon. When the rotating part rises to the right position, the tenon and the tenon fit each other, so that the rotating part is connected to the rotating rod at this position, and the two maintain the same rotation speed, thereby realizing the drying action of the rotating part.

[0486] 4. The rotating part is provided with a through hole 9 for juice discharge only on the side wall.

[0487] 5. There are no wear-resistant parts 22 on the upper end surface and bottom surface of the tool.

[0488] 6. Whether the cutter rotates clockwise or counterclockwise, it can push up the rotating part when it rises, so that it disengages from the bottom of the barrel and continues to rise.

[0489] The rest is the same as Example 1.

[0490] Example 8

[0491] In this embodiment, Fig. 9 As shown, it is different from Example 7 in that:

[0492] 1. The opening 32 at the upper end of the rotating part is small and located at the edge of the upper end of the rotating part. The sleeve holes are arranged at the bottom and the upper end of the rotating part. The rotating rod passes through the two sleeve holes, and the upper cover 20 is only used to put the food to be processed when it is opened or to close the opening when it is closed.

[0493] 2. Tenons 31 are respectively provided on the upper left side of the rotating part and the upper right side of the rotating part, and tenons are provided on the plate-shaped component aligned with the tenons.

[0494] 3. The tool is connected with a clamping part located below the rotating part. The clamping part is arranged at the lower end of the outer edge of the sleeve 33 arranged below the tool, or can be directly arranged at the bottom or side wall of the tool through a bent structure. The clamping part can drag the rotating part up when the tool rises, and the tool can support the rotating part to descend when the rotating part descends.

[0495] 4. Only one protruding plate is arranged at the bottom of the rotating part, while two protruding plates are arranged at the bottom of the barrel body. The protruding plate at the bottom of the rotating part can be blocked and rotated to a limited position by the two protruding plates at the bottom of the barrel body.

[0496] 5. There are no wear-resistant parts 22 on the upper end surface and bottom surface of the tool.

[0497] 6. Whether the cutter rotates clockwise or counterclockwise, it can push up the rotating part when it rises, so that it disengages from the bottom of the barrel and continues to rise.

[0503] 3. A boss 13 is provided at the bottom of the barrel, a tenon groove 30 is provided on the boss, and a tenon 31 is provided at the bottom of the rotating part. When the rotating part descends to this position, the tenon and the tenon groove are inserted and matched with each other, thereby limiting the rotating part so that it remains stationary or can only shake within a small range. When the rotating part rises, the tenon and the tenon groove are disengaged, and the limit of the rotating part is released.

[0504] 4. Whether the cutter rotates clockwise or counterclockwise, it can push up the rotating part when it rises, so that it disengages from the bottom of the barrel and continues to rise.

A plate-shaped component 29 is provided on the upper section of the rotating rod, and a tenon 30 is provided on the surface of the component facing the rotating part, and a tenon 31 is provided on the upper end surface of the upper cover opposite to the tenon. When the rotating part rises to the position, the tenon and the tenon fit each other, so that the rotating part is connected to the rotating rod at this position, and the two maintain the same rotation speed, thereby realizing the drying action of the rotating part.

[0517] 3. Wear-resistant parts 22 are provided on the upper end surface and bottom surface of the tool.

[0540] The difference between this embodiment and embodiment 1 is that:

[0541] The tool is made of ceramic material, and a permanent magnet is embedded in the inner edge of the sleeve hole at the upper end of the rotating part. The permanent magnet is magnetically attracted to the inner magnetic attraction part in the rotating rod. The rise or fall of the rotating part drives the tool to rise or fall.

[0542] The rest is the same as Example 1.

[0543] Embodiment 17

[0544] The difference between this embodiment and embodiment 10 is that:

[0545] The tool is made of ceramic material, and a permanent magnet is embedded at the bottom of the rotating part. The permanent magnet is magnetically attracted to the inner magnetic attraction part in the rotating rod. The rise or fall of the rotating part drives the tool to rise or fall.

[0546] The rest is the same as Example 1.

[0547] Embodiment 18

[0548] The difference between this embodiment and embodiment 1 is that:

[0549] The upper section of the rotating rod passes upward from the end cover, and the upper end surface of the rotating rod is in an open state.

[0551] Embodiment 19

[0552] In this embodiment, Fig. 20 As shown, the transverse cross-section of the rotating rod from the upper section to the lower section is circular and an elongated key block is provided from the upper section to the lower section, the tool is provided with a key slot matching the elongated key block, and the sleeve hole of the rotating part is also provided with a key slot matching the elongated key block.

[0553] The tool rises or falls under the magnetic attraction of the inner magnetic attraction part in the rotating rod, and rotates under the driving of the rotating rod. The rotating part rises as the tool rises and falls as the tool falls, and the rotating part rotates under the driving of the rotating rod.

[0554] In the present invention, a driving part, a telescopic part, a screw and a nut, a single nut and other structures are arranged in the rotating rod. The vertical movement of the driving part, the telescopic part, the screw and the nut, the single nut and other structures realizes the rising or falling of the inner magnetic part. The rising or falling action can drive the rotating part or the cutter to rise or fall through the external magnetic part, thereby realizing the crushing of the food to be processed when the cutter rotates and the throwing out of the juice in the residue when the rotating part rotates. Due to the vertical relative displacement between the tool and the rotating part, the tool can more efficiently crush the food to be processed placed in the rotating part; secondly, there is no threaded fit between the tool and the rotating rod, and the residue is not easy to be retained, and the phenomenon of massive reproduction of pathogens due to the corruption of residues in the prior art will not occur; in addition, the surface of the rotating rod is flat, and the problem of massive reproduction of pathogens due to the corruption of external thread residues and the impact on the lifting and lowering (vertical movement) of the tool in the prior art will not occur; in the entire processing process, the rotating rod seals the structure inside it, and the whole is easy to disassemble and clean; finally, the closed rotating rod has a certain damping effect on the internal magnetic suction part of the lifting and lowering movement (vertical movement) inside it, avoiding the vibration, noise and other hazards caused by its rapid rise or rapid descent and violent impact on other structures.

22. A food processor with residue and juice separation and spin-drying functions according to claim 1 or 2 or 3 or 5 or 6 or 7 or 9 or 10 or 12 or 13 or 14 or 16 or 17 or 20 or 21, characterized in that: When the rotating part moves to the lower end of the barrel body, it is limited by the rotation limiting structure or is in a free state, and the rotation limiting structure is selected from any one of (1), (2), (3), (4) or (5): (1) An insertion structure or a clamping structure is provided between the bottom of the barrel body or at least one of the side walls at the lower end of the barrel body and the bottom of the rotating part; or, (2) An insertion structure or a clamping structure is provided between at least one of the bottom of the barrel or the side wall of the lower end of the barrel and the side wall of the rotating part; or, (3) An engaging structure is provided between the bottom of the barrel body or at least one of the side walls of the lower end of the barrel body and the bottom of the rotating part; or, (4) An engaging structure is provided between at least one of the bottom of the barrel body or the side wall of the lower end of the barrel body and the side wall of the rotating part; or, ⑸ The inner side wall at the lower end of the barrel body is in a shape that is adapted to the lower end of the side wall of the rotating part, and this shape can block the rotation of the rotating part.

23. A food processor with residue and juice separation and spin-drying functions according to claim 5 or 6 or 7 or 9 or 10 or 12 or 13 or 14 or 16 or 17 or 20 or 21, characterized in that: The inner magnetic attraction part is located in the closed hollow structure rotating rod, and divides the rotating rod into at least two spaces along the vertical direction. The structural relationship between the inner magnetic attraction part and the rotating rod is one of the following: (1) There is fluid in the space inside the rotating rod, and different spaces have a structure that is interconnected. When the inner magnetic attraction part moves vertically inside the rotating rod, the interconnected structure can make the fluid in different spaces inside the rotating rod flow, thereby buffering the vertical movement of the inner magnetic attraction part inside the rotating rod; or, (2) There is gas in the space inside the rotating rod, and different spaces are isolated from each other. When the inner magnetic attraction part moves vertically inside the rotating rod, the gas in the space inside the rotating rod is compressed, which has a buffering effect on the vertical movement of the inner magnetic attraction part inside the rotating rod.
