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 a solid-liquid separation function. Background Art

[0002] A food processor is a device for crushing food materials. The cutter inside the food processor has a high rotation speed, which can reach 16,000 to 30,000 revolutions per minute. The high-speed rotating cutter crushes the food materials and releases the vitamins, minerals, phytochemicals, proteins, water and other ingredients they contain. When some food materials are crushed, a large amount of solids will remain, such as the pomace after crushing apples and the dregs after crushing soybeans. These solids remain in the liquid, and the taste is reduced when drinking directly. If the later filtration method is used, the liquid in the solids cannot be completely precipitated, resulting in a waste of nutrition.

[0003] How to effectively separate the solid and liquid after the food is crushed is an important task. For example, the Chinese patent with the announcement number CN204192427U discloses a high-speed wall-breaking extraction device for fresh edible and medicinal materials, including an extraction cup, a high-speed motor, an extraction blade, a control module, and a main housing. The high-speed motor is placed at the bottom of the main housing, and the extraction blade can be connected to the high-speed motor drive, and the high-speed motor is electrically connected to the control module; the extraction device also includes a centrifugal cup, which is arranged in the extraction cup; the centrifugal cup is a cup wall with a filter pore structure, which can be connected to the high-speed motor drive, and can separate the liquid from the outside of the centrifugal cup into the extraction cup under high-speed rotation. This scheme is a device for further separating and extracting liquid juice from fresh edible and medicinal materials that have been broken into a fluid or paste by a high-speed extraction blade. It mainly uses the centrifugal principle of the centrifugal cup to separate liquid juice and fiber residues and other substances and collect them in the extraction cup.

[0004] The above patent uses an extraction blade to crush the edible and medicinal materials, and then uses the high-speed rotation of the centrifugal cup to separate the solid and liquid. The separated liquid flows out through the liquid intake port of the extraction cup and is collected in an external container. This structure can indeed separate the solid and liquid after crushing, but there are the following problems:

[0005] 1. Paragraph 0006 of the invention content states that the centrifugal cup 6 is not driven to rotate by the high-speed motor 2 when the wall is broken at high speed, and the centrifugal cup is driven to rotate by the high-speed motor when separation is required after the wall is broken at high speed. Paragraph 0017 of the specification describes that the crushing and centrifugation are not performed at the same time, and the clutch can switch the rotation of the extraction blade 5 and the rotation of the centrifugal cup.

[0006] It can be seen from the above content that the clutch is a key component, which can be switched to drive the extraction blade or the centrifugal cup. However, the specific implementation method, including the external and internal structure of the clutch for switching and the specific working process, is not recorded in the specification and the drawings. Therefore, the clutch is unclear, that is, the technical solution disclosed in the patent that the centrifugal cup can stop rotating during crushing and rotate during solid-liquid separation is simply impossible to achieve.

[0007] 2. Even though the structure of the clutch switching the extraction blade and the centrifugal cup is clear, the realization of its clutch function is divided into electromagnetic method, magnetic powder method, friction method and hydraulic method. No matter which method is used, when the clutch is disengaged or engaged, the high speed (several thousand to tens of thousands of revolutions) generated instantly by the high-speed motor 2 will cause strong impact or friction on the clutch, seriously endangering the working safety of the internal structure of the clutch.

[0008] 3. Even if the internal structure of the above clutch is strong enough to withstand the impact or friction caused by high speed, Figure 1 It can be seen that the bottom of the clutch is set at the upper end of the main engine housing 3. When the high-speed motor rotates at high speed, the vibration generated at the clutch will be transmitted to the main engine housing, the high-speed motor inside the main engine housing and other components. When the vibration reaches a certain intensity, it will cause damage to the overall structure.

[0009] 4. The above patent first crushes the food and medicinal materials, and then drives the centrifugal cup to rotate to separate liquid juice, fiber residue and other substances and collect them in the extraction cup. When the extraction blade is crushing the food, the greater the relative speed between the extraction blade and the crushed food and medicinal materials, the better the crushing effect, and vice versa. When the relative speed between the extraction blade and the food and medicinal materials is small to a certain extent, they cannot even be crushed, and the subsequent "separation of fiber residues" is out of the question. The purpose of the above patent using a clutch to connect the blade and the centrifugal cup is also to prevent the centrifugal cup from being driven to rotate during crushing, so as to achieve a good crushing effect. However, in fact, due to the existence of crushing resistance, liquid viscosity, friction, etc., even when the clutch is in a disengaged state, the rotation of the tool will drive the centrifugal cup to rotate in the same direction, resulting in a very poor crushing effect, and even making it impossible to achieve the purpose of the invention:

[0010] (1) The cutting resistance of the extraction blade when crushing edible and medicinal materials causes the centrifugal cup to rotate: When the extraction blade rotates in the centrifugal cup to crush edible and medicinal materials, the edible and medicinal materials will produce a large resistance to the blade, thereby generating a force that causes the centrifugal cup to rotate in the same direction, thereby driving the centrifugal cup to rotate, reducing the relative speed between the edible and medicinal materials and the extraction blade, which is not conducive to crushing.

[0011] (2) The rotation of the centrifuge cup is caused by the viscous force of the food liquid: The extraction blade rotates at a high speed inside the centrifuge cup to crush food materials. In most cases, there is water or juice in the extraction cup. The high-speed rotation of the extraction blade will drive the juice to rotate violently, and the high-speed rotating juice will then drive the centrifuge cup to rotate (the centrifuge cup is used to hold all the food materials to be crushed, so the volume of the centrifuge cup is relatively large, which makes it easier for the centrifuge cup to be driven by the high-speed rotating juice). This reduces the relative speed between the extraction blade and the food materials and is not conducive to crushing.

[0012] (3) The rotation of the centrifuge cup is caused by the frictional force: The clutch connects the high-speed motor, the extraction blade, and the centrifuge cup. When the clutch is in a separated state from the centrifuge cup, the centrifuge cup (not engaged with the clutch) is in a free state. In theory, the centrifuge cup cannot be driven to rotate by the high-speed motor at this time, but in fact, there is a frictional force between the clutch and the centrifuge cup. To prevent the leakage of lubricants and the like inside the clutch, the clutch is covered with a water-sealing sleeve including sealing devices such as sealing rings. As a result, there must be sealing rings at many places in the connection structure of "high-speed motor - clutch - extraction blade - centrifuge cup". To ensure the reliability of the seal and maintain the necessary seal life, the sealing rings are very tight. This causes a large frictional force between the contact surfaces of these sealing rings and the parts to be sealed. This frictional force causes the centrifuge cup to still be driven to rotate by the rotation of the high-speed motor and the extraction blade even when the clutch is in a separated state from the centrifuge cup, reducing the relative speed between the extraction blade and the centrifuge cup and being not conducive to the extraction blade crushing food.

[0013] In summary, how to achieve safe and effective separation of food material crushing and solid-liquid separation through structural improvement remains a problem to be solved. Summary of the Invention

[0014] The purpose of the present invention is to overcome the deficiencies of the prior art and provide a food processor with a solid-liquid separation function that has a reasonable structure, can effectively prevent the rotation of the centrifuge cup during food material crushing, effectively distinguish the food material crushing process and the solid-liquid separation process, and can work safely.

[0086] The present invention will be further described below in conjunction with embodiments. The following embodiments are illustrative and not restrictive, and the protection scope of the present invention cannot be limited by the following embodiments.

[0087] The tool mentioned in the present invention generally refers to the total name of the crushing tool device or crushing device of a food processor, which includes impact crushing tools, shear crushing tools, grinding devices with cooperating dynamic and static grinding heads, etc. It can be driven by the power unit of the food processor to rotate or turn and thus crush food materials.

[0088] In particular, the shear crushing tool includes a main tool and an auxiliary tool. In the shear crushing tool, the main tool is the main part. The main tool is arranged on the tool shaft and driven by the tool shaft. The auxiliary tool is arranged on the inner edge of the centrifugal cup. When there is a speed difference between the main tool and the auxiliary tool, a shearing and crushing effect is produced on the food material (however, when the distance between the two is too far, the shearing and crushing effect produced is weak). Therefore, for the shear crushing tool, the working state of the main tool is mainly concerned, and the auxiliary tool is not described. For example, when the tool rotation is involved in the present invention, if the shear crushing tool is involved, this expression describes the rotation state of the main tool, and the description of the auxiliary tool is omitted.

[0089] The grinding device with cooperating dynamic and static grinding heads 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 sleeved on the tool shaft and driven by the tool shaft. The static grinding head is arranged on the inner edge of the centrifugal cup. Therefore, for the grinding device with cooperating dynamic and static grinding heads, the working state of the dynamic grinding head is mainly concerned, and the static grinding head is not described.

[0090] A food processor with a solid-liquid separation function, as shown in the figure, includes a power unit 22, a tool 11, a centrifugal cup 7 and a barrel 4. The barrel is arranged at the upper end of the housing 23 of the power unit (of course, the barrel can also be arranged at the lower end of the housing 23 of the power unit). A centrifugal cup is arranged in the barrel. The centrifugal cup is provided with filter holes 9. A tool is arranged in the centrifugal cup. The tool is driven by the power unit. The centrifugal cup is connected to the power unit through a clutch 13. The innovation of the present invention lies in: the state relationship between the clutch and the centrifugal cup is:

[0091] The clutch is in the disengaged state. The power unit drives the tool to rotate, and the rotational speed of the centrifugal cup under the action of external resistance is lower than that of the tool or is zero; when the clutch is in the engaged state, the power unit drives the centrifugal cup and the tool to rotate.

[0092] The clutch has various structures, including but not limited to the following Structure One or Structure Two:

[0093] Structure One is as Figure 5 shown. The clutch includes a power input component and a power output component, and an engagement and disengagement component is arranged between the power input component and the power output component; the power input component is connected to the tool shaft and rotates with the rotation of the tool shaft, and the power output component is connected to the centrifugal cup.

[0094] The state relationship between the engagement and disengagement component and the centrifugal cup is:

[0095] When the engagement and disengagement component is in the disengaged state, the input component and the output component are in the disengaged state. The power unit rotates and drives the tool to rotate through the tool shaft. The tool shaft drives the power input component to rotate, and the rotational speed of the centrifugal cup under the action of external resistance is lower than that of the tool or is zero. When the external resistance disappears, the engagement and disengagement component is in the engaged state, the input component and the output component are in the engaged state. The power unit rotates and drives the tool to rotate through the tool shaft, and the tool shaft drives the centrifugal cup to rotate with the rotation of the tool through the power input component, the engagement and disengagement component and the power output component.

[0096] The disappearance of the above-mentioned external resistance and the engagement state of the engagement and disengagement component are two independent processes, that is, the disappearance of the external resistance is achieved by its acting components or structures, while the engagement state of the engagement and disengagement component is achieved by other acting components or structures.

[0097] Structure Two is as Figures 1 to 4 shown. The clutch is a one-way clutch.

[0098] The state relationship between the one-way clutch and the centrifugal cup is:

[0099] When the one-way clutch is in the disengaged state, the power unit rotates forward and drives the tool to rotate, and the rotational speed of the centrifugal cup under the action of external resistance is lower than that of the tool or is zero. When the external resistance disappears, the one-way clutch is in the engaged state, and the power unit rotates backward and drives the centrifugal cup and the tool to rotate.

[0100] The preferred solution is: the power unit is a motor.

[0101] The one-way clutch includes an inner rotating component and an outer rotating component. The inner rotating component is arranged inside the outer rotating component, and a one-way locking component is arranged between the inner rotating component and the outer rotating component; the inner rotating component is sleeved on the outer edge of the tool shaft of the tool, the outer rotating component is connected to the centrifugal cup, and the inner rotating component rotates with the rotation of the tool shaft.

[0102] The state relationship between the one-way locking component and the centrifugal cup is as follows:

[0103] The one-way locking component is in a separated state. The power unit rotates forward and drives the tool to rotate. The centrifugal cup rotates at a speed lower than that of the tool shaft or stops rotating under the action of external resistance. When the external resistance disappears, the one-way locking component is in an engaged state, and the power unit rotates backward and drives the centrifugal cup and the tool to rotate.

[0104] The disappearance of the above-mentioned external resistance and the one-way locking component being in the engaged state are two independent processes. That is, the disappearance of the external resistance is achieved by its corresponding acting component or structure, while the one-way locking component being in the engaged state is achieved by another acting component or structure.

[0105] The above-mentioned forward rotation and reverse rotation are for the convenience of explaining two opposite rotation directions. For example: the forward rotation can be a clockwise rotation in the horizontal direction, and the reverse rotation is a counterclockwise rotation in the horizontal direction; another example: the forward rotation can also be a counterclockwise rotation in the horizontal direction, and the reverse rotation is a clockwise rotation in the horizontal direction.

[0106] Whether it is Structure 1 or Structure 2, when the speed difference between the tool and the centrifugal cup is the largest, the tool has the best effect on crushing the food ingredients. At this time, the state is that the tool rotates at the maximum speed and the centrifugal cup stops rotating. When the speed difference between the tool and the centrifugal cup is small, the effect of the tool on crushing the food ingredients becomes worse. At this time, the state is that the tool rotates (the maximum speed is better) and the centrifugal cup rotates at a non-zero speed. When the speeds of the tool and the centrifugal cup are the same, the effect of the tool on crushing the food ingredients is the worst, and it is basically impossible to effectively crush the food ingredients.

[0107] When the food ingredient crushing is completed, the centrifugal cup can best eject the liquid into the barrel only after its rotation speed reaches the maximum. At this time, the state is that the centrifugal cup rotates at the maximum speed, and the tool can rotate together with the centrifugal cup.

[0108] For Structure 1, the clutch can use common clutch structures such as friction clutches and electromagnetic clutches, such as Figure 6As shown, the clutch is an electromagnetic clutch, and its structure is as follows: The power input component includes a driving disk 41 and key blocks 40. The driving disk is sleeved on the outer edge of the cutter shaft 12 above the bottom plate 17 of the barrel body, and multiple key blocks are arranged on the upper end face. The power output component includes a driven disk 37 and a connecting sleeve 35. The driven disk is sleeved at an interval of 36 on the outer edge of the cutter shaft above the electromagnet. The lower end of the connecting sleeve is connected to the upper end face of the driven disk, and the upper end of the connecting sleeve is connected to the bottom of the centrifugal cup. The cutter shaft located within the connecting sleeve is also arranged at an interval of 36 from the inner edge of the connecting sleeve. The engagement and disengagement component includes an electromagnetic coil (not shown in the figure) on the driving disk and a spring (not shown in the figure) arranged between the driving disk and the driven disk. In order to protect each component from being corroded by the food juice, protective covers 39 are sleeved on the driving disk, the driven disk, and the lower end of the connecting sleeve, and a rotating and sliding sealing structure is arranged between the connecting sleeve and the protective cover. The inside of the driven disk is made of ferromagnetic material or is internally provided with a permanent magnet and an electromagnet.

[0109] The working process of Structure One is as follows:

[0110] (1) When the driving disk rotates with the cutter shaft, the electromagnetic coil loses power, and the driven disk is separated from the driving disk under the action of the spring. The centrifugal cup is also in a state of being separated from the driving disk. The centrifugal cup stops rotating under the action of external resistance, the rotational speed of the cutter is the maximum, and the food crushing process is completed.

[0111] (2) After the food crushing is completed, the cutter shaft stops rotating, while the electromagnetic coil is powered on and generates a magnetic field, attracting the driven disk downward. The connecting sleeve drives the centrifugal cup to move downward as well. The rotation of the cutter shaft causes the key blocks to be inserted into the key slots 38 of the driven disk, making the driving disk and the driven disk stably engaged together. When the cutter shaft rotates again, the cutter shaft drives the centrifugal cup to rotate at high speed through the driving disk, the driven disk, and the connecting sleeve. The centrifugal cup throws the liquid in the solid-liquid mixture inside it into the barrel body (while the centrifugal cup rotates, the cutter also rotates with the cutter shaft, but it does not affect the separation of the solid and the liquid). After the centrifugal cup rotates for a period of time, the solid-liquid separation process is completed.

[0112] In addition to the above-mentioned electromagnetic clutch, Structure One can also be other types such as a friction clutch, etc., and their working processes are the same.

[0113] For Structure Two, the one-way clutch can be a device with one-way transmission function such as an overrunning clutch, a one-way bearing, or a check valve (the outer ring is not fixed), etc. Its structure is as follows: The inner rotating component is also called the inner race, inner ring, inner circle, etc., and the outer rotating component is also called the outer race, outer ring, outer circle, etc. The one-way locking component includes wedge blocks, rollers, or ratchets. Here, the working principle of one-way operation will be described using the inner race, outer race, and wedge blocks. The inner race is sleeved inside the outer race, and a cage is sleeved on the outer edge of the inner race. Multiple wedge blocks are arranged between the cage and the inner edge of the outer race. The function of the cage is to make the wedge blocks always tilt slightly in the direction of locking the outer race to strengthen the locking function of the wedge blocks. Inside the protective frame.

[0114] The working process of Structure II is as follows. The reference numerals of the inner race, the wedge block, and the outer race can be referred to Figure 7 and 8 :

[0115] (1) When the inner race 46 rotates forward with the cutter shaft 12, the wedge block 45 is in a position where it does not lock the outer race, and the outer race 47 does not rotate (the inner race and the outer race are in a separated state). The centrifugal cup stops rotating under the action of an external resistance (the external resistance is any one or two or all three of the following blocking force, frictional force, or electromagnetic force), the rotational speed of the cutter is maximum, and the process of crushing the food ingredients is completed.

[0116] (2) After the food ingredient crushing is completed, the external resistance (the external resistance is any one or two or all three of the following blocking force, frictional force, or electromagnetic force) disappears. The power unit drives the cutter shaft to rotate in the reverse direction. The inner race rotates in the reverse direction with the cutter shaft. The wedge block is in a position where it locks the outer race, and the outer race rotates (the inner race and the outer race are in an engaged state), and drives the centrifugal cup to rotate with the rotation of the cutter shaft. The centrifugal cup throws the liquid in the solid-liquid mixture inside it into the barrel (while the centrifugal cup rotates, the cutter also rotates with the cutter shaft, but it does not affect the separation of the solid and the liquid). After the centrifugal cup rotates for a period of time, the process of solid-liquid separation is completed.

[0117] Although the combinations of other inner rings, outer rings and wedge blocks or the combinations of inner circles, outer circles and rollers have different names, their working processes are the same.

[0118] The external resistance is mentioned in both Structure I and Structure II. The function of this external resistance is to keep the rotational speed of the centrifugal cup at the minimum state (optimally zero state) during the crushing of the food ingredients, so that the rotational speed difference between the cutter and the centrifugal cup is the largest during the food ingredient crushing process. The external resistance can be any one or two or all three of the blocking force, frictional force, or electromagnetic force. The blocking force, frictional force, or electromagnetic force is generated by the following structures:

[0123] Among them, the electromagnetic unit includes a first magnetic attraction part and a second magnetic attraction part, and the first magnetic attraction part and the second magnetic attraction part can attract or repel each other magnetically when the power unit rotates forward. The first magnetic attraction part is a ferromagnetic material, a permanent magnet or an electromagnet provided on the centrifugal cup; the second magnetic attraction part is a ferromagnetic material, a permanent magnet or an electromagnet provided on the barrel or the housing in a corresponding position. A preferred solution is that at least one of the first magnetic attraction part and the second magnetic attraction part is an electromagnet. A more preferred solution is as follows Figure 1 shown: Part or all of the centrifugal cup is a ferromagnetic material or a permanent magnet 16 (the first magnetic attraction part), and an electromagnet 18 (the second magnetic attraction part) is provided at the bottom of the barrel or the upper end of the housing. The first magnetic attraction part can magnetically attract the second magnetic attraction part, and can limit the centrifugal cup more effectively.

[0130] (6) At least one pawl is provided at the outer edge of the one-way clutch, and the teeth of a ratchet are provided at the corresponding position of the barrel. The fit between the pawl and the teeth forms the blocking force; or,

[0131] (7) At least one groove or hole is provided at the upper end, bottom or side wall of the centrifuge cup, and a telescopic tenon is provided at the corresponding position of the barrel body (preferably, the tenon is an electrically controlled tenon, such as a push-pull electromagnet, etc. The push-pull structure forms a pushing and pulling action through the magnetic core and electromagnetic coil of the electromagnet. The magnetic core moves like a piston), and the plug-in fit between the tenon and the groove or hole after the tenon extends out forms the blocking force; or,

[0132] (8) At least one telescopic tenon is provided at the upper end, bottom or side wall of the centrifuge cup, and a groove or hole is provided at the corresponding position of the barrel body. The plug-in fit between the tenon and the groove or hole after the tenon extends out forms the blocking force.

[0133] In addition to the blocking units described in (1) to (8) above, the following blocking units of any one of (1) or (2) can also be used, and the structure can be referred to Figure 7 , 8 :

[0134] (1) As Figure 7 shown, the cutter shaft is fixedly or detachably connected to the inner rotating member 46 in the one-way clutch 13, the outer rotating member 47 in the one-way clutch is fixedly or detachably connected to the upper end, side wall or bottom 15 of the centrifuge cup, the outer rotating member 47 in the one-way clutch is sleeved with the limiting inner rotating member 44 in the limiting one-way clutch, and the limiting outer rotating member 42 of the limiting one-way clutch is fixedly or detachably connected to the upper end, side wall or bottom of the barrel body.

[0135] The state relationship between the limiting one-way clutch and the one-way clutch is:

[0136] When the limiting one-way clutch is in the engaged state, the one-way clutch is in the disengaged state. The power unit rotates forward and drives the cutter to rotate, and the centrifuge cup rotates at a speed of zero under the action of the blocking force of the limiting outer rotating member in the limiting one-way clutch. When the limiting one-way clutch is in the disengaged state, the one-way clutch is in the engaged state, and the power unit rotates backward and drives the centrifuge cup and the cutter to rotate; or,

[0137] (2) As Figure 8 shown, the cutter shaft is fixedly or detachably connected to the inner rotating member 46 in the one-way clutch 13, the outer rotating member 47 in the one-way clutch is fixedly or detachably connected to the upper end, side wall or bottom of the centrifuge cup, the upper end, side wall or bottom of the centrifuge cup is sleeved with the limiting inner rotating member 44 in the limiting one-way clutch, and the limiting outer rotating member 42 of the limiting one-way clutch is fixedly or detachably connected to the upper end, side wall or bottom of the barrel body 4;

[0138] The state relationship between the limiting one-way clutch and the one-way clutch is:

[0139] When the limiting one-way clutch is in the engaged state, the one-way clutch is in the disengaged state. The power unit rotates forward and drives the tool to rotate. The centrifugal cup rotates at zero speed under the action of the blocking force of the limiting outer rotating component in the limiting one-way clutch. When the limiting one-way clutch is in the disengaged state, the one-way clutch is in the engaged state. The power unit rotates reversely and drives the centrifugal cup and the tool to rotate.

[0140] The friction unit is selected from any one of (1), (2), (3), or (4), such as Figure 5 shown:

[0141] (1) A retractable friction block 33 is provided on the upper end, side wall or bottom of the barrel body, and the friction block can contact the upper end, side wall or bottom of the centrifugal cup to form a frictional force; or,

[0142] (2) A retractable friction block is provided on the upper end, bottom or side wall of the centrifugal cup, and the friction block can contact the upper end, side wall or bottom of the barrel body to form a frictional force; or,

[0143] (3) A retractable friction block is provided on the outer rotating component in the one-way clutch, and the friction block can contact the upper end, side wall or bottom of the barrel body to form a frictional force; or,

[0144] (4) A retractable friction block is provided on the upper end, side wall or bottom of the barrel body, and the friction block can contact the outer rotating component in the one-way clutch to form a frictional force.

[0145] The power unit is a packaged integral structure, which includes components such as a motor and a reducer. As Figure 1 shown, the output shaft 21 of the power unit can be an integral long shaft with the tool shaft 12. The long shaft passes through the rotary sealing structure 20 at the upper end of the housing 19 and the bottom 17 of the barrel body and extends into the centrifugal cup, and a tool is installed at its upper end. The relationship between the output shaft and the tool shaft can also be as Figure 2 , 3 , 4, 5 shown. A half coupling 27 is connected to the upper end of the output shaft, and another half coupling is connected to the lower end of the tool shaft. The two half couplings are combined to form an integral coupling, that is, the power unit drives the tool to rotate through the output shaft, the coupling and the tool shaft.

[0146] Example 1

[0147] This example is as Figure 1 shown. The barrel body 4 is provided with an upper cover 5, and the lower end is arranged at the upper end of the housing 23. A liquid outlet pipe 2 is arranged at the bottom of the barrel body, a control valve 3 is arranged on the liquid outlet pipe, and the lower end of the liquid outlet pipe communicates with the container 1.

[0148] The output shaft 21 of the power unit and the cutter shaft 12 are an integral long shaft. A fixed structure 14 is provided on the outer edge between the centrifugal cup and the bottom of the barrel body. The fixed structure is fixedly connected to the inner race of the one-way clutch 13 by means of meshing, clamping, etc. The outer race of the one-way clutch is connected to the bottom 15 of the centrifugal cup, and a cutter 11 is provided at the upper end of the cutter shaft.

[0149] An end cover 6 is provided at the upper end opening of the centrifugal cup. A plurality of filter holes 10 are provided on the side wall of the centrifugal cup. The ingredients to be crushed are placed in the space 8 inside the centrifugal cup. A plurality of wedges are provided inside the one-way clutch.

[0150] Three permanent magnets 16 are radially and evenly distributed on the bottom surface of the centrifugal cup. The angle of each permanent magnet in the plane of the bottom surface of the centrifugal cup is 120 degrees. The magnetic pole of each permanent magnet facing the bottom of the barrel body is the S pole. Three electromagnets 18 are radially provided at the upper end of the outer shell below the barrel body. The distribution of the electromagnets is the same as that of the permanent magnets. The magnetic pole of each electromagnet facing the bottom surface of the centrifugal cup is the N pole. In this way, when the permanent magnet at the bottom of the centrifugal cup rotates to the position of the electromagnet, a magnetic attraction can be generated between the electromagnet and the permanent magnet, thereby restricting the position of the centrifugal cup.

[0151] The working process of this embodiment is as follows:

[0152] (1) Open the upper cover, place the centrifugal cup into the barrel body and fix it on the fixed structure on the cutter shaft. Open the end cover, put apple pieces into the centrifugal cup, and then tighten the end cover and the upper cover.

[0153] (2) Start the power unit to rotate it forward and drive the cutter shaft to rotate. When the inner race rotates forward with the cutter shaft, the wedges are in a position where they do not lock the outer race. The outer race does not rotate, and the centrifugal cup also remains non-rotating with the outer race. However, since the cutter rotates to cut the apple pieces and generates a thrust on the apple pieces, and the apple pieces drive the centrifugal cup to rotate through friction. When the permanent magnet at the bottom of the centrifugal cup rotates and aligns with the electromagnet below the barrel body, a magnetic attraction is generated between the permanent magnet and the electromagnet, and the centrifugal cup is limited from rotating. After the cutter rotates at a high speed for a period of time, the process of crushing the ingredients is completed.

[0154] The above-mentioned limiting is specifically:

[0155] ① The magnetic attraction between the permanent magnet and the electromagnet is less than the frictional force between the apple pieces and the centrifugal cup. At the beginning, the centrifugal cup rotates a certain angle (the rotation speed is lower than the speed of the cutter), and the apple pieces are continuously crushed. When the frictional force is less than the magnetic attraction, the rotation speed of the centrifugal cup is zero. Or,

[0156] ② The magnetic attraction between the permanent magnet and the electromagnet is greater than the frictional force between the apple pieces and the centrifugal cup, and the centrifugal cup is in a stationary state.

[0157] (3) After the crushing is completed, the power unit drives the cutter shaft to rotate in the reverse direction. The inner race rotates with the cutter shaft in the reverse direction. The wedge block is in a position towards locking the outer race. The outer race rotates and drives the centrifugal cup to rotate with the cutter shaft. The centrifugal cup throws the liquid in its solid-liquid mixture into the barrel (while the centrifugal cup rotates, the cutter also rotates with the cutter shaft, but it does not affect the separation of the solid and liquid). After the centrifugal cup rotates for a period of time, the solid-liquid separation process is completed.

[0158] (4) During the drying process of the centrifugal cup, the control valve of the liquid outlet pipe is opened to allow the apple juice in the barrel to flow into the container. When there is no more juice flowing out, close the control valve and take away the container.

[0159] Embodiment 2

[0160] This embodiment is as Figure 2 shown. The difference between this embodiment and Embodiment 1 is that:

[0161] The one-way drive unit uses a one-way bearing.

[0162] A half coupling 27 is connected to the upper end of the output shaft, and a half coupling is connected to the lower end of the cutter shaft. The two half couplings are combined together, so that the power unit drives the cutter to rotate through the output shaft, the coupling and the cutter shaft.

[0163] Two baffles 24 are arranged on both sides of the bottom surface of the centrifugal cup, and two limit plates 25 are arranged corresponding to the bottom of the barrel. Each limit plate can extend or retract towards the bottom surface of the centrifugal cup under the drive of a feeding mechanism 26 such as an electric push rod, a rack and pinion, or a pneumatic component on the bottom surface of the barrel.

[0164] The limit of the centrifugal cup in this embodiment is completed by the extension of the limit plate. That is, when the cutter rotates forward, due to the frictional force of the apple blocks in the centrifugal cup on the centrifugal cup, the centrifugal cup first rotates a certain angle. When the centrifugal cup rotates a certain angle, the baffle on its bottom surface touches the extended limit plate. At this time, the centrifugal cup stops under the action of the blocking force between the limit plate and the baffle, and is in a state where the rotation speed is zero.

[0165] The above-mentioned limit plate can be arranged on the side wall of the barrel, and the baffle is arranged on the side wall of the centrifugal cup. The limit plate extends along the radial direction of the centrifugal cup and realizes the purpose of blocking the rotation of the centrifugal cup by touching the baffle.

[0166] The others are the same as those in Embodiment 1.

[0167] Embodiment 3

[0168] This embodiment is as Figure 3 shown. The difference between this embodiment and Embodiment 2 is that:

[0169] The one-way drive unit uses a backstop.

[0170] A ratchet wheel 28 is provided on the bottom surface of the centrifuge cup or the shape of the teeth of the ratchet wheel is provided. One or more pawls 29 are hinged to the bottom of the barrel body. The pawls can catch the ratchet wheel or engage with the teeth when the tool rotates forward, so as to quickly stop the centrifuge cup.

[0171] Setting a pawl on the bottom surface of the centrifuge cup and setting a ratchet wheel or the shape of the teeth of the ratchet wheel on the bottom of the barrel body can also achieve the limit of the centrifuge cup. Setting the pawl on the side wall of the barrel body and setting the shape of the teeth on the side wall of the centrifuge cup can also achieve the limit of the centrifuge cup.

[0172] Others are the same as in Embodiment 2.

[0173] Embodiment 4

[0174] As shown in this embodiment Figure 4 The difference between this embodiment and Embodiment 2 is that:

[0175] The one-way transmission unit uses an overrunning clutch.

[0176] The overrunning clutch has a relatively large vertical height. A ratchet wheel or a shape of radially distributed teeth 30 is provided at the lower end of the outer edge of the overrunning clutch. A hinge seat 31 is provided at the bottom of the barrel body. A pawl 29 is provided on the surface of the hinge seat opposite to the ratchet wheel or the teeth.

[0177] The pawl catches the ratchet wheel or engages with the teeth to limit the centrifuge cup.

[0178] Others are the same as in Embodiment 2.

[0179] Embodiment 5

[0180] As shown in this embodiment Figure 5 The difference between this embodiment and Embodiment 2 is that:

[0181] A retractable friction block 33 is provided on the side wall of the barrel body. The friction block is connected to the moving end 34 of a feed mechanism 26 such as an electric push rod, a rack and pinion, or a pneumatic component provided on the side wall of the barrel body.

[0182] The feed mechanism operates to extend the moving end towards the side wall of the centrifuge cup. The surface of the friction block contacts the surface 32 of the side wall of the centrifuge cup, and the centrifuge cup cannot rotate, so as to limit the centrifuge cup.

[0183] Others are the same as in Embodiment 2.

[0184] Embodiment 6

[0185] As shown in this embodiment Figure 5 The difference between this embodiment and Embodiment 5 is that:

[0186] A telescopic tenon 33 is provided on the side wall of the barrel body, and the tenon is connected to the moving end 34 of a feeding mechanism 26 such as an electric push rod, a rack and pinion, and a pneumatic component provided on the side wall of the barrel body.

[0187] When the feeding mechanism operates, the moving end extends toward the side wall of the centrifuge cup, the tenon is inserted into a groove provided in the centrifuge cup for alignment, and the centrifuge cup is limited.

[0188] Others are the same as those in Embodiment 5.

[0189] Embodiment 7

[0190] As shown in this embodiment Figure 6 The difference between this embodiment and Embodiment 1 is as follows:

[0191] The clutch is an electromagnetic clutch. The power input component includes a driving disk 41 and key blocks 40. The driving disk is sleeved on the outer edge of a cutter shaft 12 above the bottom plate 17 of the barrel body, and a plurality of key blocks are provided on the upper end surface. The power output component includes a driven disk 37 and a connecting sleeve 35. The driven disk is sleeved at intervals 36 on the outer edge of the cutter shaft above the electromagnet. The lower end of the connecting sleeve is connected to the upper end surface of the driven disk, and the upper end of the connecting sleeve is connected to the bottom of the centrifuge cup. The cutter shaft located in the connecting sleeve is also arranged at intervals 36 from the inner edge of the connecting sleeve. The engaging and disengaging component includes an electromagnetic coil (not shown in the figure) on the driving disk and a spring (not shown in the figure) provided between the driving disk and the driven disk. In order to protect each component from being corroded by the food material juice, protective covers 39 are sleeved on the driving disk, the driven disk, and the lower end of the connecting sleeve, and a rotating and sliding sealing structure is provided between the connecting sleeve and the protective cover. The inside of the driven disk is a permanent magnet.

[0192] The working process of this embodiment is as follows:

[0193] (1) When the driving disk rotates with the cutter shaft, the electromagnetic coil loses power, the driven disk is separated from the driving disk under the action of the spring, and the centrifuge cup is also in a state of being separated from the driving disk. The centrifuge cup stops rotating under the action of external resistance, the rotational speed of the cutter is maximum, and the food material crushing process is completed.

[0194] (2) After the food material crushing is completed, the cutter shaft stops rotating, and the electromagnetic coil is powered on and generates a magnetic field, attracting the driven disk downward. The connecting sleeve drives the centrifuge cup to move downward as well. The rotation of the cutter shaft causes the key blocks to be embedded in the slots 38 of the driven disk, enabling the driving disk and the driven disk to be stably engaged together. The cutter shaft drives the centrifuge cup to rotate at high speed through the driving disk, the driven disk, and the connecting sleeve. The centrifuge cup throws the liquid in the solid-liquid mixture inside it into the barrel body (while the centrifuge cup rotates, the cutter also rotates with the cutter shaft, but it does not affect the solid-liquid separation). After the centrifuge cup rotates for a period of time, the solid-liquid separation process is completed.

[0195] The external resistance in step (1) is the same as that in Embodiment 1.

[0196] Embodiment 8

[0197] As shown in this embodiment Figure 7 This embodiment is different from Embodiment 1 in that:

[0198] The cutter shaft is fixedly or detachably connected to the inner rotating member 46 in the one-way clutch 13. The outer rotating member 47 in the one-way clutch is fixedly or detachably connected to the bottom 15 of the centrifugal cup (the upper end or side wall 10 of the centrifugal cup can also be connected to the outer rotating member of the one-way clutch through a conventional connecting structure such as a bracket). The extension 48 at the lower end of the outer rotating member 47 in the one-way clutch is sleeved with the limiting inner rotating member 44 in the limiting one-way clutch. The limiting outer rotating member 42 of the limiting one-way clutch is fixedly or detachably connected to the upper end, side wall or bottom 17 of the barrel (or the extended section 49 of the outer rotating member is fixedly or detachably connected to the upper end, side wall or bottom of the barrel).

[0199] The state relationship between the limiting one-way clutch and the one-way clutch is that when the limiting one-way clutch is in the engaged state, the one-way clutch is in the disengaged state. When the limiting one-way clutch is in the disengaged state, the one-way clutch is in the engaged state.

[0200] When the power unit rotates forward and drives the cutter shaft to rotate, the cutter shaft drives the inner rotating member and the cutter to rotate forward. The one-way clutch is in the disengaged state, and the outer rotating member of the one-way clutch is in the disengaged state. The limiting one-way locking member 43 in the limiting one-way clutch makes the limiting inner rotating member and the limiting outer rotating member in the engaged state. The limiting outer rotating member is fixed to the barrel. Therefore, the barrel and the limiting outer rotating member provide a blocking force for the limiting inner rotating member through the limiting one-way locking member, and the limiting inner rotating member transmits the blocking force to the outer rotating member of the one-way clutch connected thereto. Thus, the centrifugal cup mounted on the outer rotating member of the one-way clutch maintains a rotational speed of zero, and the cutter completes the process of crushing food ingredients.

[0201] When the power unit rotates in the reverse direction and drives the cutter shaft to rotate, the cutter shaft drives the inner rotating member and the cutter to rotate in the reverse direction. The one-way clutch is in the engaged state, and the outer rotating member of the one-way clutch is in the engaged state. The outer rotating member drives the centrifugal cup mounted thereon to rotate together with the cutter shaft. And the limiting one-way locking member in the limiting one-way clutch makes the limiting inner rotating member and the limiting outer rotating member in the disengaged state. Therefore, the aforementioned blocking force disappears, and the centrifugal cup maintains the maximum rotational speed, and the centrifugal cup completes the solid-liquid separation process.

[0202] The outer rotating member of the one-way clutch and the limiting inner rotating member of the limiting one-way clutch can also be integrally formed, that is, the two can be one component.

[0203] Embodiment 9

[0204] As shown in this embodiment Figure 8As shown, the difference between this embodiment and Embodiment 7 is as follows:

[0205] The outer rotating member 47 in the one-way clutch is fixedly or detachably connected to the bottom 15 of the centrifugal cup through the connecting portion 50. The side wall 10 of the centrifugal cup is sleeved with the limiting inner rotating member 44 in the limiting one-way clutch (if the limiting one-way clutch is arranged at the upper outer edge of the centrifugal cup, the upper end and side wall of the centrifugal cup can also be connected to the outer rotating member of the one-way clutch through conventional connecting structures such as brackets). The limiting outer rotating member 42 of the limiting one-way clutch is fixedly or detachably connected to the upper end, side wall or bottom of the barrel 4.

[0206] The state relationship between the limiting one-way clutch and the one-way clutch is as follows: when the limiting one-way clutch is in the engaged state, the one-way clutch is in the separated state; when the limiting one-way clutch is in the separated state, the one-way clutch is in the engaged state.

[0207] When the power unit rotates forward and drives the cutter shaft to rotate, the cutter shaft drives the inner rotating member and the cutter to rotate forward. The one-way clutch is in the separated state, and the outer rotating member of the one-way clutch is in the separated state. The limiting one-way locking member in the limiting one-way clutch makes the limiting inner rotating member and the limiting outer rotating member in the engaged state. The limiting outer rotating member is fixed to the barrel, so the barrel and the limiting outer rotating member provide a blocking force for the limiting inner rotating member through the limiting one-way locking member, and the limiting inner rotating member transmits the blocking force to the outer rotating member of the one-way clutch connected thereto, thereby keeping the centrifugal cup mounted on the outer rotating member of the one-way clutch at a rotational speed of zero, and the cutter completes the process of crushing the food ingredients.

[0208] When the power unit rotates backward and drives the cutter shaft to rotate, the cutter shaft drives the inner rotating member and the cutter to rotate backward. The one-way clutch is in the engaged state, and the outer rotating member of the one-way clutch is in the engaged state. The outer rotating member drives the centrifugal cup mounted thereon to rotate together with the cutter shaft. The limiting one-way locking member in the limiting one-way clutch makes the limiting inner rotating member and the limiting outer rotating member in the separated state, so the aforementioned blocking force disappears, the centrifugal cup maintains the maximum rotational speed, and the centrifugal cup completes the solid-liquid separation process.

[0209] The outer rotating member of the one-way clutch can also be integrally formed with the aforementioned connecting portion 50, and the limiting outer rotating member of the limiting one-way clutch can also be integrally formed with the barrel.

[0210] In the present invention, first, the power unit directly drives the cutting tool through an integrated output shaft and cutter shaft, or the power unit drives the cutting tool through the output shaft, two mutually engaged half couplings and the cutter shaft. In either case, the impact in the prior art can be avoided, and the vibration hazard during operation is reduced. Secondly, the combination of the one-way clutch sleeved on the cutter shaft and the external resistance generated by the electromagnetic unit, the blocking unit and the friction unit realizes the speed difference between the cutting tool and the centrifugal cup during crushing and the high-speed rotation of the centrifugal cup during solid-liquid separation, effectively separating the food material crushing process and the solid-liquid separation process, and improving the working efficiency. In summary, the present invention overcomes the deficiencies of the prior art, can work safely and effectively separate solids and liquids, and is a food processor with a reasonable structure and convenient use.
