Description

Technical Field

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

[0002] Existing food processors typically consist of a main unit and a detachable processing assembly mounted on top of the main unit. The main unit houses a motor that is connected to the processing assembly. When processing food, the user places the ingredients into the processing assembly, and the motor drives the processing components to rotate, thus processing the ingredients. While this type of machine has a relatively high rotational speed, its output torque is low. When processing ingredients requiring high torque, typically at 25-60 rpm with a torque of 10-30 N·m, such as juicing or kneading dough, this type of machine is ineffective. To address this, some manufacturers have added a gearbox between the motor and the processing assembly. The reduction gears within the gearbox increase the motor's output torque, enabling the processing assembly to handle ingredients requiring high torque and meet user needs.

[0003] However, because the gearbox and motor are fixed as an independent unit, the axial height of this type of machine is greatly increased compared to a food processor with only a motor. For example, Chinese invention patent CN117145947 A discloses a gearbox structure and a juicer including the gearbox structure. Due to the high load at low speeds, the motor assembly is prone to shaking due to uneven force. The entire drive unit will swing around the contact point between the motor and the housing, which will cause the output shaft of the gearbox to wobble. Since the mechanical hard connection makes it difficult for the output shaft to automatically return to its original position during rotation, the swing of the output shaft of the gearbox will inevitably drive the screw in the food processor, such as the juicer, to swing as well. The fit clearance between the screw and the extrusion cylinder is small, which will cause friction noise between the screw and the extrusion cylinder. It will also cause the powder generated by the friction between the extrusion cylinder and the screw to enter the juice, causing food safety problems. Moreover, when the gearbox swings, it will greatly reduce its coaxiality with the motor, which will cause friction noise or even jamming and transmission failure due to misalignment between the motor and the gearbox, seriously affecting the user experience. Utility Model Content

[0004] The purpose of this utility model is to provide a screw extrusion food processing machine with a stable structure. Under the premise that existing food processing machines increase torque by adding a gearbox between the motor and the processing components, how to avoid the problem that the screw swings due to the large swing amplitude caused by the motor and gearbox being fixed as one unit, resulting in noise and wear, and the reduced coaxiality between the gearbox and the motor.

[0005] To achieve the above objectives, this utility model provides a structurally stable screw extrusion food processing machine, including a main unit and a detachable processing component located above the main unit. The main unit contains a motor and a gearbox that drives the screw through the gearbox. The main unit includes a housing that accommodates the motor and the gearbox. The top wall of the housing has a first mounting groove, and the bottom wall of the housing has a second mounting groove. The top of the gearbox extends into the first mounting groove, and the bottom of the motor extends into the second mounting groove. The food processing machine also includes a first shock-absorbing pad that isolates the first mounting groove and the gearbox, and a second shock-absorbing pad that isolates the second mounting groove and the motor.

[0006] This application incorporates a reduction gearbox between the motor and the processing component. This allows the motor to reduce torque before transmitting it to the processing component, enabling the processing component to output greater torque and meet user needs. Simultaneously, the top wall of the housing has a first mounting groove, and the bottom wall has a second mounting groove. The top of the reduction gearbox extends into the first mounting groove, and the bottom of the motor extends into the second mounting groove. This connection between the motor and the reduction gearbox forms a drive assembly, and the first and second mounting grooves provide stable positioning at the top and bottom of the entire drive assembly, ensuring the stability of the motor and reduction gearbox positions and thus improving the overall structural stability of the food processing machine. Furthermore, a first damping pad is provided between the first mounting groove and the reduction gearbox, and a second damping pad is provided between the second mounting groove and the motor. This provides flexible clamping between the top and bottom of the reduction gearbox and the motor, effectively preventing rigid collisions between the motor and the reduction gearbox and the first and second mounting grooves during operation. This reduces noise and vibration, contributing to improved overall machine stability.

[0007] Meanwhile, with the gearbox and motor fixed as one unit, when the gearbox swings during operation, the first shock-absorbing pad provides all-around flexible support to the top of the gearbox. On the one hand, when the gearbox swings too much, the first shock-absorbing pad, especially its sidewall, can effectively buffer the movement. With the elastic restoring force of the first shock-absorbing pad, the gearbox can quickly reset, achieving flexible self-adaptive return. This prevents the output shaft of the gearbox from swinging along with the screw, causing friction and noise between the screw and the extrusion cylinder, and preventing wear on the screw and extrusion cylinder, which could lead to powder falling off and contaminating the food. This ensures the stability of food processing. On the other hand, the flexible self-adaptive return of the first shock-absorbing pad ensures the coaxiality of the output shaft of the gearbox and motor, thus ensuring the transmission efficiency of both. This avoids friction noise or even transmission failure caused by misalignment between the motor and gearbox, further ensuring the stability of the entire machine.

[0008] In a preferred embodiment of a structurally stable screw extrusion food processing machine, the first damping pad includes a first side pad that circumferentially covers the side wall of the gearbox, the first side pad extending downward and protruding out of the opening of the first mounting groove;

[0009] The second damping pad includes a second side pad that circumferentially covers the side wall of the motor, and the second side pad extends upward and protrudes from the opening of the second mounting groove.

[0010] By configuring the first shock-absorbing pad as a first side pad that circumferentially covers the side wall of the gearbox, and the first side pad extends downward and protrudes from the opening of the first mounting groove, the first shock-absorbing pad achieves all-round flexible isolation between the gearbox and the side wall of the first mounting groove through the first side pad, thereby greatly improving the shock absorption effect and return effect of the first shock-absorbing pad, further improving the adaptive return speed of the gearbox, thereby further reducing the friction between the screw and the extrusion cylinder and the friction between the gearbox and the motor, and further improving the stability of the whole machine operation.

[0011] By configuring the second shock-absorbing pad as a second side pad that circumferentially covers the side wall of the motor, and the second side pad extending upward and protruding from the groove of the second mounting slot, the second shock-absorbing pad achieves all-round flexible isolation between the motor and the side wall of the second mounting slot through the second side pad, further improving the shock absorption effect of the second shock-absorbing pad, effectively reducing the vibration transmission during motor operation, further optimizing the noise control of the whole machine, ensuring the stability and durability of the equipment under high load operation, and improving the user experience.

[0012] In a preferred embodiment of a structurally stable screw extrusion food processing machine, a circumferential anti-rotation structure is provided between the first shock-absorbing pad and the first mounting groove or gearbox.

[0013] By providing a circumferential anti-rotation structure between the first damping pad and the first mounting groove, the stability of the connection between the first damping pad and the first mounting groove is improved. This prevents the situation where the gearbox drives the first damping pad to rotate relative to the first mounting groove after the motor transmits torque to the gearbox, causing the gearbox to fail to transmit torque to the screw. This ensures the stability of the torque transmission of the whole machine and also prevents the first damping pad from moving, which would cause its damping effect to deteriorate.

[0014] By providing a circumferential anti-rotation structure between the first damping pad and the gearbox, the stability of the connection between the first damping pad and the gearbox is effectively improved. This prevents the gearbox from rotating relative to the first damping pad after the motor transmits torque to the gearbox, which would cause torque transmission failure. This ensures stable transmission between the gearbox and the motor and further optimizes the overall operating efficiency of the machine.

[0015] In a preferred embodiment of a structurally stable screw extrusion food processing machine, a circumferential anti-rotation structure is disposed between a first damping pad and a first mounting groove. The side wall of the first mounting groove is provided with an inwardly extending rib, and the outer wall of the first damping pad is provided with an anti-rotation groove that cooperates with the rib. The circumferential anti-rotation structure includes the rib and the anti-rotation groove.

[0016] By setting the circumferential anti-rotation structure to include a rib and an anti-rotation groove, the sidewall of the rib and the sidewall of the anti-rotation groove are circumferentially abutted and limited after the rib extends into the anti-rotation groove. This achieves circumferential anti-rotation of the first mounting groove on the first damping pad, effectively improving the stability of the cooperation between the two, preventing relative rotation caused by vibration or torque transmission, and ensuring continuous and stable damping effect.

[0017] In a preferred embodiment of a structurally stable screw extrusion food processing machine, a circumferential anti-rotation structure is disposed between a first damping pad and a gearbox. The top wall of the gearbox housing is provided with an outwardly extending insert, and the inner wall of the first damping pad is provided with a slot that engages with the insert. The circumferential anti-rotation structure includes the insert and the slot.

[0018] By setting the circumferential anti-rotation structure to include a rib and a slot, after the rib is inserted into the slot, the side wall of the rib and the side wall of the slot achieve circumferential contact and limitation, thereby achieving circumferential anti-rotation of the gearbox by the first shock-absorbing pad. This effectively prevents relative rotation caused by vibration or torque transmission, ensures stable transmission between the gearbox and the motor, and further improves the overall smoothness and durability of the machine.

[0019] In a preferred embodiment of a structurally stable screw extrusion food processing machine, the bottom end of the motor is provided with a protrusion that is radially reduced relative to the motor body to accommodate the lower bearing, and the second shock-absorbing pad is provided with a clearance hole for the protrusion to pass through.

[0020] By providing clearance holes for the protrusion to pass through in the second damping pad, it is ensured that the protrusion will not interfere with the second damping pad during installation. At the same time, the motor shaft extending from the bottom of the motor can be cleared through the clearance holes, ensuring that the motor shaft will not interfere with the second damping pad during rotation. This avoids noise caused by relative friction between the two, and also reduces the amount of material used for demolding the second damping pad, thereby reducing production costs and improving the overall compactness of the structure.

[0021] In a preferred embodiment of a structurally stable screw extrusion food processing machine, the bottom wall of the second mounting groove is provided with multiple upwardly extending support ribs, and the support ribs are supported and surrounded below the clearance hole.

[0022] By providing multiple upward-extending support ribs on the bottom wall of the second mounting groove, and with the support ribs supporting and surrounding the area below the clearance hole, when the protrusion protrudes downward through the clearance hole, the clearance space formed by the support ribs below the clearance hole can prevent the protrusion from contacting the bottom wall of the second mounting groove. This effectively avoids friction between the motor shaft at the bottom of the motor and the bottom wall of the second mounting groove, and also avoids direct contact between the protrusion and the bottom wall of the second mounting groove, reducing heat and wear caused by friction, and helping to further reduce vibration and noise.

[0023] In a preferred embodiment of a structurally stable screw extrusion food processing machine, the side wall of the second mounting groove is provided with multiple inwardly extending limiting ribs, which abut against the outer side wall of the second shock-absorbing pad.

[0024] By providing multiple inwardly extending limiting ribs on the side wall of the second mounting groove, and having the limiting ribs abut against the outer side wall of the second damping pad, the second damping pad and the limiting ribs achieve an interference fit, thereby enhancing the radial limiting effect of the side wall of the second mounting groove on the side wall of the second damping pad, thus enhancing the radial limiting effect of the second damping pad on the motor, further improving the stability of the motor position, and ensuring the stability of the entire machine's transmission operation.

[0025] In a preferred embodiment of a structurally stable screw extrusion food processing machine, the motor is equipped with carbon brushes, and the side wall of the second mounting slot is provided with a clearance groove that is radially aligned with the carbon brushes.

[0026] By providing a clearance groove on the side wall of the second mounting slot that is radially aligned with the carbon brush, the sparks and carbon powder generated by the carbon brush during motor operation can be discharged outward through the clearance groove, preventing the carbon brush sparks from burning the second damping pad and thus protecting the second damping pad. At the same time, it prevents carbon powder from accumulating inside the motor, reducing the impact on the motor's insulation performance, extending the motor's service life, and ensuring the long-term stable operation of the food processing machine.

[0027] In a preferred embodiment of a structurally stable screw extrusion food processing machine, the main unit is further provided with a control board for controlling the operation of the motor, the motor is provided with a wire harness extending from the bottom end of the motor and electrically connected to the control board, and the bottom wall of the second shock-absorbing pad is provided with a downwardly recessed groove to form a wire outlet groove for accommodating the wire harness.

[0028] By providing a downwardly recessed groove on the bottom wall of the second shock-absorbing pad to accommodate the wire harness, the wire harness can be accommodated in the groove and led outward, effectively avoiding direct contact between the wire harness and the motor, reducing wire harness wear, ensuring circuit stability, improving the overall safety and reliability of the equipment, and extending its service life.

Detailed Implementation

[0043] To more clearly illustrate the overall concept of this utility model, a detailed description will be provided below with reference to the accompanying drawings.

[0044] 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.

[0045] like Figures 1 to 11 As shown, this utility model provides a structurally stable screw extrusion food processing machine, including a main unit 1 and a detachable processing component located above the main unit 1. The main unit 1 contains a motor 2 and a gearbox 3 that is connected between the motor 2 and the processing component. The screw is driven by the gearbox. The main unit 1 includes a housing 11 that houses the motor 2 and the gearbox 3. The top wall of the housing 11 has a first mounting groove 111, and the bottom wall of the housing 11 has a second mounting groove 112. The top of the gearbox 3 extends into the first mounting groove 111, and the bottom of the motor 2 extends into the second mounting groove 112. The food processing machine also includes a first shock-absorbing pad 4 that isolates the first mounting groove 111 and the gearbox 3, and a second shock-absorbing pad 5 that isolates the second mounting groove 112 and the motor 2.

[0046] This application incorporates a reduction gearbox 3 between the motor 2 and the processing component. This allows the motor 2 to transmit torque to the processing component after being reduced in speed by the reduction gearbox 3, enabling the processing component to output greater torque and meet user requirements. Simultaneously, the top wall of the housing 11 has a first mounting groove 111, and the bottom wall has a second mounting groove 112. The top of the reduction gearbox 3 extends into the first mounting groove 111, and the bottom of the motor 2 extends into the second mounting groove 112. This connection between the motor 2 and the reduction gearbox 3 forms a drive assembly. The first and second mounting grooves 111 and 112 provide stable positioning of the top and bottom of the entire drive assembly, ensuring the stability of the motor 2 and the reduction gearbox 3, thereby improving the overall structural stability of the food processing machine. Furthermore, a first shock-absorbing pad 4 is provided between the first mounting slot 111 and the gearbox 3, and a second shock-absorbing pad 5 is provided between the second mounting slot 112 and the motor 2. This achieves flexible clamping of the top and bottom of the gearbox 3 and the motor 2, effectively preventing rigid collisions between the gearbox 3 and the first mounting slot 111 and between the motor 2 and the second mounting slot 112 when the motor 2 is working. This reduces noise and vibration and helps improve the stability of the whole machine.

[0047] Meanwhile, after the gearbox 3 and motor 2 are fixed together, when the gearbox 3 swings during operation, the first shock-absorbing pad 4 provides all-around flexible contact with the top of the gearbox 3. On the one hand, when the swing amplitude of the gearbox 3 is too large, the first shock-absorbing pad 4, especially the side wall of the first shock-absorbing pad 4, can effectively buffer the movement. With the help of the elastic restoring force of the first shock-absorbing pad 4, the gearbox 3 can quickly reset, achieving flexible adaptive return of the gearbox 3. This avoids the output shaft of the gearbox 3 swinging, causing the screw 6 to swing along with it, resulting in friction between the screw 6 and the extrusion cylinder 7 and generating a lot of noise. It also prevents wear on the screw 6 and the extrusion cylinder 7, which could lead to the powder falling off the screw and contaminating the food. This ensures the stability of food processing. On the other hand, the flexible adaptive return of the first shock-absorbing pad 4 ensures the coaxiality of the output shaft of the gearbox 3 and motor 2, thereby ensuring the transmission efficiency of both. This avoids friction noise or even transmission failure caused by misalignment between the motor 2 and the gearbox 3, further ensuring the stability of the entire machine operation.

[0048] It should be noted that this application does not specifically limit the connection structure between the gearbox 3 and the motor 2. As a preferred embodiment of this application, the gearbox 3 and the motor 2 are directly abutted and fixedly connected by fasteners such as bolts, thereby effectively reducing the displacement caused by vibration, further improving the coaxiality of the two, and thus further improving the stability of the whole machine operation.

[0049] As a preferred embodiment of this application, such as Figure 2As shown, the first shock-absorbing pad 4 includes a first side pad 41 that circumferentially covers the side wall of the gearbox 3. The first side pad 41 extends downward and protrudes from the opening of the first mounting groove 111.

[0050] By setting the first shock-absorbing pad 4 to include a first side pad 41 that circumferentially covers the side wall of the gearbox 3, and the first side pad 41 extends downward and protrudes from the opening of the first mounting groove 111, the first shock-absorbing pad 4 achieves all-round flexible isolation between the gearbox 3 and the side wall of the first mounting groove 111 through the first side pad 41, thereby greatly improving the shock absorption effect and return effect of the first shock-absorbing pad 4, further improving the adaptive return speed of the gearbox 3, thereby further reducing the friction between the screw 6 and the extrusion cylinder 7 and the friction between the gearbox 3 and the motor 2, and further improving the stability of the whole machine operation.

[0051] As a preferred embodiment of this application, such as Figure 3 As shown, the second shock-absorbing pad 5 includes a second side pad 51 that circumferentially covers the side wall of the motor 2. The second side pad 51 extends upward and protrudes from the opening of the second mounting groove 112.

[0052] By configuring the second shock-absorbing pad 5 as a second side pad 51 that circumferentially covers the side wall of the motor 2, and the second side pad 51 extending upward and protruding from the groove of the second mounting groove 112, the second shock-absorbing pad 5 achieves all-round flexible isolation between the motor 2 and the side wall of the second mounting groove 112 through the second side pad 51, further improving the shock absorption effect of the second shock-absorbing pad 5, effectively reducing the vibration transmission during the operation of the motor 2, further optimizing the noise control of the whole machine, ensuring the stability and durability of the equipment under high load operation, and improving the user experience.

[0053] As a preferred embodiment of this application, such as Figure 5 , Figure 7 , Figure 8 , Figure 9 As shown, a circumferential anti-rotation structure is provided between the first shock-absorbing pad 4 and the first mounting groove 111 or the gearbox 3.

[0054] By providing a circumferential anti-rotation structure between the first damping pad 4 and the first mounting groove 111, the stability of the connection and cooperation between the first damping pad 4 and the first mounting groove 111 is improved. This prevents the situation where the motor 2 transmits torque to the reduction gearbox 3, and the reduction gearbox 3 drives the first damping pad 4 to rotate relative to the first mounting groove 111, causing the reduction gearbox 3 to fail to transmit torque to the screw 6. This ensures the stability of the torque transmission of the whole machine and also prevents the first damping pad 4 from moving, which would cause its damping effect to deteriorate.

[0055] By providing a circumferential anti-rotation structure between the first damping pad 4 and the gearbox 3, the stability of the connection between the first damping pad 4 and the gearbox 3 is effectively improved. This prevents the gearbox 3 from rotating relative to the first damping pad 4 after the motor 2 transmits torque to the gearbox 3, thus avoiding torque transmission failure. This ensures stable transmission between the gearbox 3 and the motor 2 and further optimizes the overall operating efficiency of the machine.

[0056] It should be noted that this application does not limit the location or specific structure of the circumferential anti-rotation structure, which can be any of the following embodiments:

[0057] Example 1: As Figure 5 , Figure 8 As shown, in this embodiment, a circumferential anti-rotation structure is disposed between the first damping pad 4 and the first mounting groove 111. The side wall of the first mounting groove 111 is provided with an inwardly extending rib 1111, and the outer wall of the first damping pad 4 is provided with an anti-rotation groove 42 that cooperates with the rib 1111. The circumferential anti-rotation structure includes the rib 1111 and the anti-rotation groove 42.

[0058] By setting the circumferential anti-rotation structure to include a rib 1111 and an anti-rotation groove 42, after the rib 1111 extends into the anti-rotation groove 42, the side wall of the rib 1111 and the side wall of the anti-rotation groove 42 achieve circumferential abutment and limitation, thereby realizing the circumferential anti-rotation of the first mounting groove 111 on the first shock-absorbing pad 4, effectively improving the stability of the cooperation between the two, preventing relative rotation caused by vibration or torque transmission, and ensuring the continuous and stable shock absorption effect.

[0059] Example 2: Figure 6 , Figure 9 As shown, in this embodiment, a circumferential anti-rotation structure is disposed between the first shock-absorbing pad 4 and the gearbox 3. The top wall of the gearbox 3 housing 11 is provided with an outwardly extending insert rib 31, and the inner wall of the first shock-absorbing pad 4 is provided with a slot 44 that engages with the insert rib 31. The circumferential anti-rotation structure includes the insert rib 31 and the slot 44.

[0060] By setting the circumferential anti-rotation structure to include a rib 31 and a slot 44, after the rib 31 is inserted into the slot 44, the side wall of the rib 31 and the side wall of the slot 44 achieve circumferential contact and limit, thereby achieving circumferential anti-rotation of the first shock-absorbing pad 4 on the gearbox 3, effectively preventing relative rotation caused by vibration or torque transmission, ensuring stable transmission between the gearbox 3 and the motor 2, and further improving the overall smoothness and durability of the machine.

[0061] Even better, such as Figures 5 to 9 As shown, a circumferential anti-rotation structure is provided between the first shock-absorbing pad 4 and the first mounting groove 111, as well as between the first shock-absorbing pad 4 and the gearbox 3. After the first shock-absorbing pad 4 forms the anti-rotation groove 42, a protrusion 43 is formed between two adjacent anti-rotation grooves 42, and the insert rib 31 is formed in the protrusion 43.

[0062] As a preferred embodiment of this application, such as Figure 3 As shown, the bottom end of the motor 2 is provided with a protrusion 21 that is radially reduced relative to the motor body to accommodate the lower bearing, and the second shock-absorbing pad 5 is provided with a clearance hole 52 for the protrusion 21 to pass through.

[0063] By providing a clearance hole 52 for the protrusion 21 to pass through in the second damping pad 5, it is ensured that the protrusion 21 will not interfere with the second damping pad 5 during installation. At the same time, the motor shaft extending from the bottom of the motor 2 can be cleared through the clearance hole 52, ensuring that the motor shaft will not interfere with the second damping pad 5 during rotation. This avoids noise caused by relative friction between the two, and at the same time reduces the amount of material used for demolding the second damping pad 5, thereby reducing production costs and improving the overall compactness of the structure.

[0064] Furthermore, such as Figure 11 As shown, the bottom wall of the second mounting groove 112 is provided with multiple upwardly extending support ribs 1121, and the support ribs 1121 support and surround the area below the clearance hole 52.

[0065] By providing multiple upwardly extending support ribs 1121 on the bottom wall of the second mounting groove 112, and with the support ribs 1121 supporting and surrounding the lower part of the clearance hole 52, when the protrusion 21 protrudes downward through the clearance hole 52, the clearance space formed by the support ribs 1121 below the clearance hole 52 can prevent the protrusion 21 from contacting the bottom wall of the second mounting groove 112. This effectively avoids the motor shaft at the bottom end of the motor 2 from rubbing against the bottom wall of the second mounting groove 112. At the same time, it also avoids direct contact between the protrusion 21 and the bottom wall of the second mounting groove 112, reducing the heat and wear generated by friction, and helping to further reduce the generation of vibration noise.

[0066] As a preferred embodiment of this application, such as Figure 11 As shown, the side wall of the second mounting groove 112 is provided with multiple inwardly extending limiting ribs 1122, and the limiting ribs 1122 abut against the outer side wall of the second shock-absorbing pad 5.

[0067] By providing multiple inwardly extending limiting ribs 1122 on the side wall of the second mounting groove 112, and having the limiting ribs 1122 abut against the outer side wall of the second damping pad 5, the second damping pad 5 and the limiting ribs 1122 achieve an interference fit, thereby enhancing the radial limiting effect of the side wall of the second mounting groove 112 on the side wall of the second damping pad 5, thus enhancing the radial limiting effect of the second damping pad 5 on the motor 2, further improving the stability of the motor 2's position, and ensuring the stability of the entire machine's transmission operation.

[0068] As a preferred embodiment of this application, such as Figure 10As shown, the motor 2 is equipped with carbon brushes 22, and the side wall of the second mounting groove 112 is provided with a clearance groove 53 that is radially aligned with the carbon brushes 22.

[0069] By providing a clearance groove 53 on the side wall of the second mounting groove 112 that is radially aligned with the carbon brush 22, the sparks and carbon powder generated by the carbon brush 22 during the operation of the motor 2 can be discharged outward through the clearance groove 53, preventing the sparks from the carbon brush 22 from burning the second shock-absorbing pad 5, thus protecting the second shock-absorbing pad 5. At the same time, it prevents carbon powder from accumulating inside the motor 2, reducing the impact on the insulation performance of the motor 2, extending the service life of the motor 2, and ensuring the long-term stable operation of the food processing machine.

[0070] As a preferred embodiment of this application, such as Figure 10 As shown, the host 1 is also equipped with a control board for controlling the operation of the motor 2. The motor 2 is equipped with a wire harness that extends from the bottom end of the motor 2 and is electrically connected to the control board. The bottom wall of the second shock-absorbing pad 5 is provided with a downward recessed groove 54 to accommodate the wire harness.

[0071] By providing a downwardly recessed groove 54 on the bottom wall of the second shock-absorbing pad 5 to accommodate the wire harness, the wire harness can be accommodated in the groove 54 and led outward, effectively avoiding direct contact between the wire harness and the motor 2, reducing wire harness wear, ensuring circuit stability, improving the overall safety and reliability of the equipment, and extending its service life.

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.
