Description

Technical Field

[0001] The utility model relates to the technical field of food grinding, in particular to a novel magnetic knife set. Background Art

[0002] With the increasing intelligence and diversification of modern household kitchen appliances, as a common household appliance, the functions and application scopes of a cooking machine are becoming more and more extensive. The grinding knife set in the cooking machine is one of its core components, mainly responsible for finely cutting, stirring and grinding food materials to meet various cooking needs. However, the existing grinding knife sets face some challenges and problems in design and use.

[0003] First of all, in order to solve the cleaning problem of the grinding knife set, the existing cooking machines usually adopt a detachable connection structure, enabling the knife head to be conveniently taken out of the machine body for thorough cleaning. However, this design also brings some safety hazards. Due to the detachable nature of the knife head, when the cooking machine is running at high speed, the knife head may fly off due to inertia, causing harm to the user. In addition, the knife head may also generate significant vibration noise due to up and down shaking during high-speed operation, affecting the use experience. Summary of the Utility Model

[0004] In order to overcome at least one of the above-mentioned defects of the prior art, the utility model provides a novel magnetic knife set, which can solve the problems of knife head detachment and excessive floating noise.

[0005] The technical solution adopted by the utility model to solve its problems is as follows:

[0006] A novel magnetic knife set, comprising: a knife disc main body, one side of the knife disc main body is provided with a convex platform protruding outward, and an assembly cavity is formed at a position corresponding to the convex platform on the other side of the knife disc main body. An installation hole is provided through the convex platform and the assembly cavity of the knife disc main body; a magnetic ring, the magnetic ring is arranged in the assembly cavity; a drive shaft, one end of the drive shaft sequentially passes through the installation hole, the magnetic ring and the assembly cavity from outside the convex platform; a combined knife set, the combined knife set is detachably connected to the other end of the drive shaft and is attracted to the magnetic ring in the convex platform.

[0007] By adopting the above solution, magnetic rings are arranged on the boss and in the assembly cavity of the cutter head body, and the combined cutter group is attracted to the magnetic rings. This magnetic attraction can ensure that the combined cutter group will not fall off and fly out due to inertia during the high-speed operation of the cooking machine, greatly improving the safety of use; the magnetic attraction between the magnetic rings and the combined cutter group can stabilize the cutter head, reduce its shaking during high-speed operation, and further reduce vibration and the resulting noise, enhancing the user experience; although the cutter head is stabilized by magnetic attraction during high-speed operation, the user can still easily disassemble the combined cutter group by disconnecting the magnetic connection for thorough cleaning and necessary maintenance.

[0008] Further, a sealing lip plate extends from the edge of the mounting hole into the assembly cavity, and the length by which the sealing lip plate extends into the assembly cavity is lower than the depth of the assembly cavity.

[0009] By adopting the above solution, it is convenient to assemble other parts in the assembly cavity without being affected by the sealing lip plate.

[0010] Further, the sealing lip plate and the assembly cavity enclose a cutter head feature groove, the magnetic ring is assembled in the cutter head feature groove, and the side of the magnetic ring away from the boss is aligned with the end face of the sealing lip plate.

[0011] By adopting the above solution, the magnetic ring can be limited in the cutter head feature groove, improving the assembly stability of the magnetic ring.

[0012] Further, a seal is arranged in the assembly cavity, and the seal is sealingly connected to the end face of the sealing lip plate.

[0013] By adopting the above solution, the part of the assembly cavity from the seal to the boss can be sealed, preventing water entering from the mounting hole from spreading to the side of the assembly cavity away from the boss.

[0014] Further, the inner hole diameter of the magnetic ring is larger than the diameter of the drive shaft.

[0015] By adopting the above solution, interference of the magnetic ring with the rotation of the drive shaft is avoided.

[0016] Further, the diameter of the mounting hole is larger than the diameter of the drive shaft.

[0017] By adopting the above solution, interference of the mounting hole with the rotation of the drive shaft is avoided.

[0018] Further, a metal collar is arranged in the assembly cavity, a rigid gasket is arranged between the metal collar and the seal, a bearing is arranged in the metal collar, and the bearing is sleeved on the surface of the drive shaft.

[0019] By adopting the above solution, the rigid gasket can play a buffering role to prevent the metal ring from excessively squeezing the seal. The bearing ensures the stability and smoothness of the drive shaft during rotation and avoids contact friction between the drive shaft and the cutter disc body.

[0020] Furthermore, a slot is provided on the inner wall of the metal ring away from one end of the rigid gasket, a fastening structure is clamped in the slot, and the fastening structure is used to limit the bearing in the metal ring.

[0021] By adopting the above solution, the position of the bearing in the metal ring can be limited, thereby ensuring that the bearing will not shift due to uneven force or vibration during operation, thereby maintaining the stability and reliability of the knife group.

[0022] Furthermore, one end of the driving shaft is connected to a driving connector, and the driving connector is used to be drivingly connected to an output end of a driving motor.

[0023] By adopting the above solution and introducing the design element of the drive connector, a stable and efficient connection bridge is established between the motor and the drive shaft. This not only improves the stability and reliability of the overall operation, but also provides users with a more convenient and quick maintenance method. At the same time, the buffering and vibration reduction effect of the drive connector also reduces the noise and vibration of the food processor during operation, improving the user experience.

[0024] Furthermore, the portion where the drive shaft is connected to the combined knife set is provided with an edge.

[0025] By adopting the above solution, the edge design can increase the contact area between the drive shaft and the combined knife group, thereby enhancing the connection stability between the two, and can prevent the combined knife group and the drive shaft from loosening or falling off due to vibration or impact during high-speed operation.

[0026] In summary, the novel magnetic knife set provided by the utility model has the following technical effects:

[0027] 1. Improve the safety of use: By setting a magnetic ring in the boss and assembly cavity of the blade body, and making the combined knife set and the magnetic ring attract each other, this magnetic attraction can ensure that the combined knife set will not fall off due to inertia when the food processor is running at high speed. This design greatly reduces the risk of the knife head falling off, thereby improving the safety of users when using the food processor;

[0028] 2. Reduce vibration and noise: The magnetic attraction between the magnetic ring and the combined knife set can stabilize the knife head and reduce its shaking during high-speed operation. As the shaking is reduced, the vibration and noise generated by the shaking will also be reduced accordingly. This not only improves the working performance of the food processor, but also improves the user experience;

[0029] 3. Convenient cleaning and maintenance: Although the combined cutter group remains stable during high-speed operation through magnetic suction, users can still easily disassemble the combined cutter group by disconnecting the magnetic connection. This design enables users to conveniently clean the combined cutter group thoroughly and perform necessary maintenance, maintaining the hygiene and good working condition of the food processor;

[0030] 4. Improved durability and stability: Due to the design of magnetic connection, the connection between the drive shaft and the combined cutter group is tighter and more stable, reducing the risk of loosening or damage caused by long-term use or frequent disassembly, which helps improve the durability and stability of the food processor.

[0040] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by those of ordinary skill in the technical field to which the present utility model belongs. The terms used in the description of the present utility model herein are only for the purpose of describing specific embodiments, and are not intended to limit the present utility model.

[0041] Embodiment 1 of the present utility model is referred to Figures 1-6 As shown, a new type of magnetic knife set is disclosed, which includes a cutter head main body 1, a magnetic ring 2, a drive shaft 3 and a combined knife set 4. An outwardly convex boss 11 is provided on one side of the cutter head main body 1, and an assembly cavity 12 is formed at a position corresponding to the boss 11 on the other side of the cutter head main body 1. The magnetic ring 2 is arranged in the assembly cavity 12; preferably, the boss 11 is arranged at the center of the cutter head main body 1, and similarly, the assembly cavity 12 is also located at the center of the cutter head main body 1; an installation hole 13 is provided through the boss 11 and the assembly cavity 12 of the cutter head main body 1. One end of the drive shaft 3 passes through the installation hole 13, the magnetic ring 2 and the assembly cavity 12 in sequence from outside the boss 11 and is connected to a drive motor. Preferably, a drive connector 8 is connected between one end of the drive shaft 3 and the output end of the drive motor, and the drive connector 8 is used for driving connection with the output end of the drive motor to improve the running stability and reliability between the drive motor and the drive shaft 3. The combined knife set 4 is detachably connected to the other end of the drive shaft 3 and attracts the magnetic ring 2 in the boss 11. Preferably, a gap is left between the boss 11 and the combined knife set 4 to avoid contact between the two, so as to improve the grinding efficiency of the combined knife set 4.

[0042] It should be noted that the material on the side of the combined cutter group 4 close to the boss 11 is a metal material that can be attracted to the magnetic ring 2. By the mutual attraction between the combined cutter group 4 and the magnetic ring 2, it is ensured that when the food processor is running at high speed, the combined cutter group 4 will not fall off and fly out due to inertia, and at the same time, the shaking during high-speed operation can be reduced, thereby reducing vibration and the resulting noise. Of course, in some embodiments, magnets can also be added to the combined cutter group 4 to increase the suction force between the combined cutter group 4 and the magnetic ring 2.

[0043] In the present Embodiment 1, referring to Figure 5 as shown, the inner hole diameter of the magnetic ring 2 is larger than the diameter of the drive shaft 3, and the diameter of the mounting hole 13 is larger than the diameter of the drive shaft 3, which can prevent the mounting hole 13 and the magnetic ring 2 from interfering with the rotation of the drive shaft 3.

[0044] To improve the assembly stability of the magnetic ring 2, in some embodiments, referring to Figure 3 and Figure 6 as shown, a sealing lip plate 121 extends from the edge of the mounting hole 13 into the assembly cavity 12. The length of the sealing lip plate 121 extending into the assembly cavity 12 is lower than the depth of the assembly cavity 12. The sealing lip plate 121 and the assembly cavity 12 enclose a cutter head feature groove 122. The magnetic ring 2 is assembled in the cutter head feature groove 122, and the side of the magnetic ring 2 away from the boss 11 is aligned with the end face of the sealing lip plate 121, which can limit the magnetic ring 2 in the cutter head feature groove 122 and improve the assembly stability of the magnetic ring 2.

[0045] To prevent water entering from the mounting hole 13 from interfering with components such as the drive motor, in some embodiments, referring to Figures 4-5 as shown, a seal 5 is provided in the assembly cavity 12. The seal 5 is sealingly connected to the end face of the sealing lip plate 121. At the same time, the seal 5 is sleeved on the drive shaft 3, which can form a seal for the part of the assembly cavity 12 from the seal 5 to the boss 11, preventing water entering from the mounting hole 13 from spreading to the side of the assembly cavity 12 away from the boss 11 and improving the working safety of the drive motor. Preferably, in the present Embodiment 1, the seal 5 is an oil seal, which can effectively block external dust, moisture and other impurities from entering the machine, thereby avoiding damage to and influence on the equipment and protecting the normal operation of the machine.

[0046] In some embodiments, referring to Figures 4-5As shown, a metal collar 7 is further provided in the assembly cavity 12. A rigid gasket 6 is provided between the metal collar 7 and the seal 5. The rigid gasket 6 can play a buffering role. A bearing 71 is provided in the metal collar 7. The bearing 71 ensures the stability and smoothness of the drive shaft 3 during rotation. The bearing 71 is sleeved on the surface of the drive shaft 3. A clamping groove member 72 is provided on the inner wall of one end of the metal collar 7 away from the rigid gasket 6. A fastening structural member 73 is clamped in the clamping groove member 72. The fastening structural member 73 is used to limit the bearing 71 in the metal collar 7, which can limit the position of the bearing 71 in the metal collar 7, and thus ensure that the bearing 71 will not shift due to uneven force or vibration during operation, so as to maintain the stability and reliability of the cutter group. In this Embodiment 1, the fastening structural member 73 is a snap ring. The snap ring is easy to install and replace, and at the same time has a large load-bearing capacity, and has the advantages of simple structure, low cost, high reliability, etc.

[0047] In some embodiments, referring to Figure 2 As shown, an edge 31 is provided on the part of the drive shaft 3 connected to the combined cutter group 4. The design of the edge 31 can increase the contact area between the drive shaft 3 and the combined cutter group 4, thereby enhancing the connection stability between the two, and can prevent loosening or falling off between the combined cutter group 4 and the drive shaft 3 due to vibration or impact during high-speed operation.

[0050] 1. Improve the use safety: By providing a magnetic ring 2 in the boss 11 and the assembly cavity 12 of the cutter head body 1, and making the combined cutter group 4 attract each other with the magnetic ring 2, this magnetic attraction can ensure that the combined cutter group 4 will not fall off and fly out due to inertia during the high-speed operation of the food processor. This design greatly reduces the risk of the cutter head falling off, thereby improving the safety of users when using the food processor;

[0051] 2. Reduce vibration and noise: The magnetic attraction between the magnetic ring 2 and the combined knife set 4 can stabilize the cutter head and reduce its wobbling during high-speed operation. Since the wobbling is reduced, the vibration and noise generated by the wobbling will also be correspondingly reduced. This not only improves the working performance of the food processor but also enhances the user experience;

[0052] 3. Facilitate cleaning and maintenance: Although the combined knife set 4 remains stable during high-speed operation through magnetic attraction, users can still easily disassemble the combined knife set 4 by disconnecting the magnetic connection. This design allows users to conveniently clean the combined knife set 4 thoroughly and perform necessary maintenance, maintaining the hygiene and good working condition of the food processor;

[0053] 4. Improve durability and stability: Due to the design of the magnetic connection, the connection between the drive shaft 3 and the combined knife set 4 is tighter and more stable, reducing the risk of loosening or damage caused by long-term use or frequent disassembly, which helps improve the durability and stability of the food processor.

[0054] The technical means disclosed in the solution of the present utility model are not limited to the technical means disclosed in the above embodiments, but also include technical solutions composed of any combination of the above technical features.
