Description

Technical Field

[0001] This utility model relates to the field of household appliance technology, specifically to a food processing machine with a simple structure. Background Technology

[0002] Existing food processing machines, such as reciprocating vegetable cutters, typically include a cutting component and a drive component with an internal motor. The cutting component includes a blade disc connected to the motor, which cuts food through its reciprocating motion. To achieve this motor-driven reciprocating motion of the blade disc, Chinese utility model patent CN202222758598.3 discloses a novel vegetable cutter that uses a crank-connecting rod mechanism between the motor shaft and the blade disc to drive the blade disc. The top of the crank connects to a connecting rod, which drives the blade disc to reciprocate. However, in actual use, this type of machine has been found to have issues. Because the connecting rod lacks axial restraint, it exhibits some wobbling during rotation, especially at higher speeds or when transmitting large torques. This wobbling can be severe, leading to unstable reciprocating motion of the blade disc and even jamming, interrupting food processing and severely impacting the user experience. Furthermore, during assembly, the large number of components and the long dimensional chain, along with manufacturing and assembly errors, make it difficult to accurately install each component. This results in significant friction and wear during transmission, greatly shortening the machine's lifespan. Utility Model Content

[0003] The purpose of this utility model is to provide a food processing machine with a simple structure to solve the problem that when existing food processing machines, such as reciprocating vegetable cutters, transmit torque from the motor to the cutter disc through a crank connecting rod, the connecting rod is not axially limited, which makes it easy for the cutter disc to wobble and get stuck.

[0004] To achieve the above objectives, this utility model provides a food processing machine with a simple structure, including a main unit, a motor installed in the main unit, and a blade assembly driven by the motor. The blade assembly includes a reciprocating blade and a turntable driven by the blade and the motor. The motor shaft is driven by the bottom end of the turntable and supports the turntable. The top of the turntable is provided with a transmission part offset relative to the rotation center of the turntable. The blade is provided with a slot for the transmission part to be inserted. The blade can move back and forth laterally in the direction of vertical reciprocating motion within the slot to drive the blade to reciprocate linearly.

[0005] This application configures the blade assembly as including a reciprocating blade and a turntable connected to the blade and motor. The motor shaft is connected to and supports the bottom of the turntable, allowing the motor shaft to directly drive the blade reciprocating motion via the eccentric turntable. Compared to existing methods using crank-connecting rods, this single turntable drives the blade, eliminating the need for a connecting rod structure, simplifying the transmission components, and reducing the transmission chain size. This makes the transmission more stable and reliable. Simultaneously, the motor shaft, supported below the turntable, limits the axial movement of the turntable, ensuring its axial position stability and effectively preventing the turntable from wobbling during transmission, which could lead to unstable reciprocating motion of the blade or even jamming and interruption of food processing. It also reduces noise generated during wobbling, improving noise reduction. Furthermore, the single intermediate transmission component reduces errors between components during production and assembly, effectively avoiding the situation where numerous transmission components result in large errors during assembly, affecting assembly efficiency or even preventing installation. It also reduces frictional noise caused by errors between components, improving transmission stability. Meanwhile, the top of the turntable is equipped with a transmission part offset relative to the rotation center of the turntable, and the cutter head is equipped with a slot for the transmission part to be inserted. The cutter head can move back and forth laterally in the direction of vertical reciprocating motion within the slot. When the motor shaft drives the cutter head to rotate, due to the eccentric setting of the transmission part, the transmission part will rotate in the circumferential direction of the driving component and slide relative to the cutter head within the slot. At the same time, the axial component force can drive the cutter head to achieve reciprocating motion, ensuring the stability of the transmission.

[0006] In a preferred embodiment of a food processing machine with a simple structure, the turntable has a connecting part that extends toward and is drivenly connected to the motor shaft, and the side wall of the motor shaft has a support part that extends radially outward, with the top wall of the support part abutting and supporting the lower part of the connecting part.

[0007] By providing a connecting part on the turntable that extends towards and is driven by the motor shaft, the turntable achieves a transmission connection with the motor shaft through the connecting part, improving the stability of the transmission connection between the turntable and the motor shaft and ensuring the transmission of high torque. Simultaneously, a support part extending radially outward is provided on the side wall of the motor shaft, with the top wall of the support part abutting against the bottom of the connecting part. This allows the motor shaft to provide axial support to the cutter head through the support part, increasing the support area of ​​the motor shaft on the cutter head, thereby improving the stability of the axial support. Furthermore, the increased support area effectively prevents the cutter head from swaying with the motor shaft as a fulcrum. Since the motor shaft rotates synchronously with the turntable, they are relatively stationary, preventing friction and wear, further enhancing the stability of the cutter head. This further prevents the turntable from shaking during transmission, which could lead to unstable reciprocating motion of the cutter head or even jamming, interrupting food processing and improving the reliability of the cutter head transmission.

[0008] In a preferred embodiment of a food processing machine with a simple structure, the cutter head assembly includes a mounting groove for accommodating the turntable and the cutter head. The mounting groove is provided with a clearance hole for the connecting part to pass through. The axial height of the clearance hole is less than the axial height of the connecting part, so that when the support part is supported below the connecting part, a clearance gap is formed between the turntable and the mounting groove.

[0009] By setting the axial height of the clearance hole to be less than the axial height of the connecting part, a clearance gap is formed between the turntable and the mounting groove when the support part is supported below the connecting part. This allows the turntable to be suspended relative to the mounting groove, achieving isolation between the turntable and the mounting groove. This effectively avoids contact between the mounting groove and the turntable, which could cause friction and generate significant noise during rotation. This helps improve the stability of the turntable during rotation, while also reducing kinetic energy loss when the turntable rubs against the mounting groove, thus improving rotation efficiency.

[0010] In a preferred embodiment of a food processing machine with a simple structure, the turntable includes a turntable body, a fixing hole at the bottom center of the turntable body, and a connecting part including the fixing hole and a coupling mounted on the fixing hole and protruding from the bottom surface of the fixing hole. The coupling is connected to the motor shaft for transmission.

[0011] By designing the connecting part as a coupling that includes a fixing hole and a bottom surface protruding from the fixing hole, compared to directly molding the connecting part on the turntable, the coupling can withstand greater torque. This effectively avoids direct contact between the turntable and the motor shaft, preventing the turntable from deforming or even breaking during torque transmission and causing transmission failure, thus improving transmission stability. Furthermore, it eliminates the need to manufacture the entire turntable as a high-strength profile, helping to reduce the turntable's manufacturing cost.

[0012] In a preferred embodiment of a food processing machine with a simple structure, the cutter head assembly includes a housing that accommodates a turntable and a cutter head. The housing includes a shell for accommodating the turntable, and a fixing member is provided on the outer bottom surface of the housing. The fixing member passes through the shell and is fixedly connected to the turntable to limit the axial movement of the turntable.

[0013] By providing a fixing member on the outer bottom surface of the housing, and fixing the fixing member through the housing and fixedly connecting it to the driving member to limit the axial movement of the driving member, the turntable can achieve further axial limitation, while ensuring the stability of the connection and cooperation between the turntable and the motor shaft. This ensures the transmission of torque on the driving member in the motor shaft and avoids the situation where the turntable cannot effectively transmit power to the motor shaft due to axial movement during rotation.

[0014] In a preferred embodiment of a food processing machine with a simple structure, the turntable has a connecting part extending toward the motor and being drivenly connected to the motor shaft, and a boss surrounding the outer periphery of the connecting part. The housing has a clearance hole through which the connecting part passes. The fixing member includes a limiting part abutting against the lower part of the surrounding wall forming the clearance hole and a main body part fixedly connected to the boss.

[0015] By configuring the fastener as a limiting part that abuts against the lower part of the enclosure wall forming the clearance hole and a main body part that is fixedly connected to the boss, the fastener can be connected to the turntable through the main body part, while the limiting part can abut against the outer bottom surface of the housing, thereby achieving axial limiting of the fastener, and thus achieving axial limiting of the turntable, ensuring the stability of the position of the driving part.

[0016] In a preferred embodiment of a food processing machine with a simple structure, the top surface of the main body is provided with an upwardly extending rib, which surrounds the outside of the boss to limit the radial movement of the boss.

[0017] By providing an upwardly extending rib on the top surface of the main body, and with the rib surrounding the outside of the boss, the fixing member can not only achieve axial positioning of the turntable through the main body and the limiting part, but also achieve radial positioning of the turntable through the limiting of the rib and the boss, ensuring the radial stability of the turntable, avoiding radial movement when the turntable rotates, further improving the stability of the turntable transmission, and reducing the generation of noise during torque transmission.

[0018] In a preferred embodiment of a food processing machine with a simple structure, the cutter head includes a cutter head body and a connector head detachably connected to the cutter head body, with a slot located at the bottom of the connector head for insertion and engagement with the transmission part.

[0019] By setting the cutter head to include the cutter head body and the connector that can be detachably connected to the cutter head body, users can switch functions simply by replacing the cutter head body if they need to change to a different type of cutter head. Compared with the method of directly connecting the cutter head body to the transmission unit, this effectively avoids the situation where the transmission unit and the slot are not tightly fitted after a long period of replacement, which would cause a lot of friction noise during the transmission process.

Detailed Implementation

[0030] To more clearly illustrate the overall concept of this utility model, a detailed description will be provided below with reference to the accompanying drawings.

[0031] It should be noted that many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the scope of protection of the present invention is not limited to the specific embodiments disclosed below.

[0032] like Figures 1 to 7As shown, this utility model provides a food processing machine with a simple structure, including a main unit 1, a motor 2 disposed in the main unit 1, and a blade disc 3 assembly that is driven and connected to the motor 2. The blade disc 3 assembly includes a reciprocating blade disc 3 and a turntable 4 that is driven and connected between the blade disc 3 and the motor 2. The motor shaft 21 of the motor 2 is driven and connected to the bottom end of the turntable 4 and supports the turntable 4. The top of the turntable 4 is provided with a transmission part 43 that is offset relative to the rotation center of the turntable 4. The blade disc 3 is provided with a slot 31 for the transmission part 43 to be inserted. The blade disc 3 can move back and forth laterally in the direction of vertical reciprocating motion within the slot 31 to drive the blade disc 3 to reciprocate linearly.

[0033] This application configures the blade disc 3 assembly as including a reciprocating blade disc 3 and a turntable 4 that is driven between the blade disc 3 and the motor 2. The motor shaft 21 of the motor 2 is driven to the bottom end of the turntable 4 and supports the turntable 4. This allows the motor shaft 21 to directly drive the blade disc 3 to reciprocate through the eccentric turntable 4. Compared with the existing method of transmission through a crank and connecting rod, the blade disc 3 can be driven by a single turntable 4, eliminating the need for a connecting rod structure, simplifying the transmission part 43, and reducing the size chain of the transmission, making the transmission more stable and reliable. At the same time, the motor shaft 21 is supported under the turntable 4, which limits the axial movement of the turntable 4 and ensures the stability of the axial position of the turntable 4. This effectively avoids the situation where the turntable 4 shakes during transmission, causing the blade disc 3 to reciprocate unstably or even jam, resulting in interruption of food processing. It also reduces the noise generated during shaking, which helps to improve the noise reduction effect. Meanwhile, the individual intermediate transmission unit 43 pieces can reduce the errors between various components during production and assembly, thereby effectively avoiding the situation where a large number of transmission units 43 pieces lead to excessive errors during assembly, affecting assembly efficiency or even making installation impossible. It can also reduce frictional noise caused by errors between components and improve the stability of the transmission. At the same time, the top of the turntable 4 is provided with a transmission unit 43 offset relative to the rotation center of the turntable 4. The cutter head 3 is provided with a slot 31 for the transmission unit 43 to be inserted. The cutter head 3 can move back and forth laterally in the direction of vertical reciprocating motion within the slot 31. When the motor shaft 21 drives the cutter head 3 to rotate, due to the eccentric setting of the transmission unit 43, the transmission unit 43 will rotate in the circumferential direction of the driving component and slide relative to the cutter head 3 within the slot 31. At the same time, the axial component force can drive the cutter head 3 to achieve reciprocating motion, ensuring the stability of the transmission.

[0034] As a preferred embodiment of this application, such as Figure 2 As shown, the turntable 4 is provided with a connecting part 41 extending toward the motor shaft 21 and being connected to the motor shaft 21 in a transmission manner. The side wall of the motor shaft 21 is provided with a support part 211 extending radially outward. The top wall of the support part 211 abuts against and is supported below the connecting part 41.

[0035] By providing a connecting part 41 that extends toward and is connected to the motor shaft 21 on the turntable 4, the turntable 4 can achieve a transmission connection with the motor shaft 21 through the connecting part 41, thereby improving the stability of the transmission connection between the turntable 4 and the motor shaft 21 and ensuring the transmission of large torque. Meanwhile, the side wall of the motor shaft 21 is provided with a support portion 211 extending radially outward, and the top wall of the support portion 211 abuts against the bottom of the connecting portion 41, so that the motor shaft 21 can achieve axial support for the cutter head 3 through the support portion 211, thereby increasing the support area of ​​the motor shaft 21 on the cutter head 3, and thus improving the stability of the axial support of the cutter head 3 by the motor shaft 21. Furthermore, as the support area increases, it can effectively prevent the cutter head 3 from swinging with the motor shaft 21 as the fulcrum. Since the motor shaft 21 rotates synchronously with the turntable 4, the two are relatively stationary and will not generate friction and wear, which helps to further improve the stability of the cutter head 3 and further prevent the turntable 4 from shaking during transmission, causing the cutter head 3 to reciprocate unstably or even jam, resulting in interruption of food processing, thus improving the reliability of the cutter head 3 transmission.

[0036] Furthermore, such as Figure 2 As shown, the cutter head 3 assembly includes a mounting groove for accommodating the turntable 4 and the cutter head 3. The mounting groove is provided with a clearance hole 51 for the connecting part 41 to pass through. The axial height of the clearance hole 51 is less than the axial height of the connecting part 41, so that when the support part 211 is supported under the connecting part 41, a clearance gap is formed between the turntable 4 and the mounting groove.

[0037] By setting the axial height of the clearance hole 51 to be less than the axial height of the connecting part 41, when the support part 211 is supported below the connecting part 41, a clearance gap is formed between the turntable 4 and the mounting groove, so that the turntable 4 is suspended relative to the mounting groove, thus isolating the turntable 4 from the mounting groove. This effectively avoids the situation where the mounting groove and the turntable 4 come into contact, causing the turntable 4 to rub against the mounting groove and generate a lot of noise when rotating. This helps to improve the stability of the turntable 4 when rotating, while reducing the kinetic energy loss when the turntable 4 rubs against the mounting groove, and improving the rotation efficiency.

[0038] It should be noted that this application does not specifically limit the structure of the connecting part 41. It can be integrally formed with the turntable 4, or it can be a preferred embodiment of this application, such as... Figure 2 , Figure 4 As shown, the turntable 4 includes a turntable 4 body, and a fixing hole 411 is provided at the bottom center of the turntable 4 body. The connecting part 41 includes the fixing hole 411 and a coupling 412 installed in the fixing hole 411 and protruding from the bottom surface of the fixing hole 411. The coupling 412 is connected to the motor shaft for transmission. More preferably, the coupling 412 is provided with a shaft hole, and the top end of the motor shaft 21 extends into the shaft hole.

[0039] By configuring the connecting part 41 as a coupling 412 that includes a fixing hole 411 and is mounted on the fixing hole 411 and protrudes from the bottom surface of the fixing hole 411, compared to directly forming the connecting part 41 on the turntable 4, the coupling 412 can withstand greater torque. This effectively avoids direct contact between the turntable 4 and the motor shaft 21, which could lead to deformation or even breakage of the turntable 4 during torque transmission, causing transmission failure and improving transmission stability. Furthermore, it eliminates the need to manufacture the entire turntable 4 as a high-strength profile, helping to reduce the manufacturing cost of the turntable 4.

[0040] It should also be noted that this application does not specifically limit the structure of the support part 211, such as... Figure 2 As shown, in a preferred embodiment of this application, the motor shaft 21 includes a first shaft body connected to the motor 2, and a second shaft body located at the end of the first shaft body. The second shaft body is radially reduced relative to the first shaft body to form a stepped portion with the stepped surface facing upwards. The stepped surface of the stepped portion serves as a support portion 211. Of course, the support portion 211 is not limited to the above-described configuration. It can also be formed by forming a radially outwardly extending flange on the side wall of the motor shaft 21, with the upper surface of the flange forming the support portion 211; or it can be formed by forming multiple outwardly extending pillars on the side wall of the motor shaft 21, with the pillars abutting below the connecting portion, and the top surface of the pillars forming the support portion 211.

[0041] As a preferred embodiment of this application, such as Figure 2 , Figure 4 As shown, the cutter head 3 assembly includes a housing that accommodates the turntable 4 and the cutter head 3. The housing includes a shell 5 for accommodating the turntable 4. A fixing member 6 is provided on the outer bottom surface of the shell 5. The fixing member 6 passes through the shell 5 and is fixedly connected to the turntable 4 to limit the axial movement of the turntable 4.

[0042] By providing a fixing member 6 on the outer bottom surface of the housing 5, and fixing the fixing member 6 through the housing 5 and fixing it to the driving member to limit the axial movement of the driving member, the turntable 4 can be further limited in the axial direction. At the same time, the stability of the connection and cooperation between the turntable 4 and the motor shaft 21 is ensured, thereby ensuring the transmission of torque from the motor shaft 21 to the driving member and avoiding the situation where the turntable 4 cannot effectively transmit power to the motor shaft 21 due to axial movement during rotation.

[0043] As a preferred embodiment, such as Figure 2 As shown, the turntable 4 is provided with a connecting part 41 extending toward the motor 2 and drivingly connected to the motor shaft 21, and a boss 42 surrounding the outer periphery of the connecting part 41. The housing 5 is provided with a clearance hole 51 through which the connecting part 41 passes. The fixing member 6 includes a limiting part 62 abutting against the lower part of the surrounding wall forming the clearance hole 51 and a main body part 61 fixedly connected to the boss 42.

[0044] By configuring the fixing member 6 as including a limiting part 62 that abuts against the lower part of the enclosure wall forming the clearance hole 51 and a main body part 61 that is fixedly connected to the boss 42, the fixing member 6 can be connected to the turntable 4 through the main body part 61, and the limiting part can abut against the outer bottom surface of the housing 5, thereby achieving axial limiting of the fixing member 6, and thus achieving axial limiting of the turntable 4, ensuring the stability of the position of the driving member.

[0045] Furthermore, such as Figure 2 As shown, the top surface of the main body 61 is provided with an upwardly extending rib 611, which surrounds the outside of the boss 42 to limit the radial movement of the boss 42.

[0046] By providing an upwardly extending rib 611 on the top surface of the main body 61, and surrounding the outside of the boss 42, the fixing member 6 can not only achieve axial positioning of the turntable 4 through the main body 61 and the limiting part 62, but also achieve radial positioning of the turntable 4 through the limiting of the rib 611 and the boss 42, ensuring the radial stability of the turntable 4, preventing radial movement when the turntable 4 rotates, further improving the stability of the turntable 4 transmission, and reducing the noise generated during torque transmission.

[0047] It should be noted that this application does not specifically limit the structure of the transmission part 43, which can be any of the following embodiments:

[0048] Example 1: In this example, the transmission part 43 is a protrusion 431 located on the top of the turntable 4.

[0049] Example 2: As Figure 2 As shown, in this embodiment, the transmission part 43 includes a protrusion 431 disposed on the top of the turntable 4 and a bearing 432 sleeved on the outside of the protrusion 431.

[0050] By setting a bearing 432 on the outside of the protrusion 431, the friction between the protrusion 431 and the slot 31 can be greatly reduced, thereby reducing the friction noise generated during rotation. At the same time, it can also improve the stability of the transmission between the slot 31 and the protrusion 431 and avoid jamming during transmission.

[0051] It should be noted that this application does not specifically limit the structure of the cutter head 3. It can be that the cutter head 3 has a slot 31 directly formed at the bottom to mate with the transmission part 43. This is a preferred embodiment of the present application. Figure 5 As shown, the cutter head 3 includes a cutter head body 33 and a connector head 32 that is detachably connected to the cutter head body 33. A slot 31 is provided at the bottom of the connector head 32 for insertion and engagement with the transmission part 43.

[0052] By setting the cutter head 3 to include a cutter head body 33 and a connector 32 that is detachably connected to the cutter head body 33, users can switch functions simply by replacing the cutter head body 33 if they need to replace different types of cutter heads 3. Compared with directly connecting the cutter head body 33 to the transmission part 43, this effectively avoids the situation where the transmission part 43 and the slot 31 do not fit tightly after a long period of replacement, resulting in large friction noise during transmission.

[0053] It should be further noted that this application does not specifically limit how the cutter head body 33 and the connector 32 achieve a detachable connection. As one preferred embodiment of this application, such as... Figure 5 , Figure 6 , Figure 7 As shown, the cutter head body 33 has a limiting protrusion 331 at the end near the connector 32, and the connector 32 has a limiting buckle 322 that is detachably connected to the limiting protrusion 331. Of course, the two can also be connected by a connector such as a screw.

[0054] As a preferred embodiment, such as Figure 7 As shown, the cutter head 3 assembly includes a housing with a mounting groove to accommodate the cutter head 3. The inner sidewall of the mounting groove is provided with a sliding groove arranged along the reciprocating motion direction of the cutter head 3. The connector 32 is provided with an elastic buckle 321 that is engaged in the sliding groove.

[0055] By providing an elastic buckle 321 that is locked in the slide groove in the connector 32, the connector 32 and the cutter head body 33 are connected as one unit. During the installation process into the mounting groove, the cutter head 3 can be installed by simply pressing down and squeezing the elastic buckle 321 to deform it. After the elastic buckle 321 is adapted to the slide groove, it can be reset. The installation process is convenient and quick, improving assembly efficiency.

[0056] As a preferred embodiment, such as Figure 7 As shown, the top of the connector 32 is provided with a gripping part 323 for the user to hold.

[0057] By providing a gripping part 323 on the connector 32, the user can hold the gripping part 323 to disassemble and remove the cutter head 3, thus improving the user experience.

It should be noted that any combination of the technical solutions of any embodiment with one or more other embodiments is within the protection scope of this utility model. Although this utility model has been described in detail above with general descriptions and specific embodiments, some modifications or improvements can be made to it, which will be obvious to those skilled in the art. Therefore, all such modifications or improvements made without departing from the spirit of this utility model are within the scope of protection claimed by this utility model.
