Description

Technical Field

[0001] The utility model relates to the technical field of household electrical appliances, in particular to a food processing machine with low working noise. Background Art

[0002] With the development of society and the improvement of living standards, people's pursuit of dietary diversity and healthy diet is constantly increasing. Therefore, various industrial food processing machines are gradually miniaturized and enter thousands of households, such as slicers and vegetable cutters, which not only meet people's needs for dietary health and nutrition, but also greatly improve people's quality of life, and are therefore loved by people.

[0003] Existing food processing machines usually include a main unit with a built-in motor, a cutter disc connected to the motor, and a guide cylinder arranged below the main unit. In order to achieve axial limitation of the cutter disc, a step portion with a step surface facing upward is usually provided on the top of the guide cylinder, and the cutter disc abuts against the step surface. At the same time, the guide cylinder also extends upward from the step surface to form a connection portion that cooperates with the main unit. The outer periphery of the cutter disc abuts against the inner side wall of the connection portion to achieve radial limitation. However, when this type of food processing machine is in use, the outer periphery of the cutter disc will have greater friction with the step surface, which will cause greater friction noise between the cutter disc and the step surface. In order to reduce the noise generation For example, Chinese utility model CN202220682867.X discloses a cutting assembly for a vegetable cutter and a handheld electric vegetable cutter, in which a convex rib in contact with the contact surface of the limiting step is provided on the outer slip ring of the knife disc, thereby reducing the contact surface between the outer slip ring and the limiting step and the sliding friction between the two, so that the rotation of the knife disc is more stable and efficient and the rotation noise of the knife disc is reduced. However, when producing this type of outer slip ring, it is necessary to first manufacture the outer slip ring and then add the convex rib on the basis of the outer slip ring, which makes the production steps of the entire outer slip ring more complicated, resulting in a significant reduction in the production efficiency of the outer slip ring and a significant increase in the production cost. Utility Model Content

[0004] The utility model aims to provide a food processing machine with low working noise, so as to solve the problem that an outer slip ring covering the outer periphery of a cutter disc in an existing food processing machine needs to be manufactured first and then convex ribs are added on the basis of the outer slip ring to solve the noise problem, but this will lead to low production efficiency and high production cost of the cutter disc.

[0005] To achieve the above-mentioned purpose, the utility model provides a food processing machine with low working noise, comprising a main machine with a built-in motor, a cutter disc connected to the motor in transmission, and a guide cylinder arranged below the main machine, the top of the guide cylinder having a step portion with a step surface facing upward and a connecting portion extending upward from the step surface to cooperate with the main machine, the outer periphery of the cutter disc is covered with an outer slip ring, at least a portion of the bottom surface and the step surface of the outer slip ring is provided with a wavy surface, and the cutter disc contacts the step surface through the wavy surface.

[0006] The present application covers the outer circumference of the cutter disc with an outer slip ring, so that the cutter disc can be protected in the circumferential direction through the outer slip ring. When the outer slip ring rubs against the inner wall and the step surface of the connecting part for a long time, if the outer slip ring is severely worn, the user can replace the outer slip ring to ensure the limiting effect of the cutter disc, avoid the need to replace the entire cutter disc, and help reduce the maintenance cost of the cutter disc. At the same time, at least one of the bottom surface and the step surface of the outer slip ring is partially provided with a wave surface, and the cutter disc contacts the step surface through the wave surface, so that when the motor drives the cutter disc to rotate, the cutter disc contacts the step surface through the wave surface, so that part of the bottom wall of the cutter disc cannot contact the step surface, thereby reducing the contact area between the entire cutter disc and the step surface. On the one hand, it can reduce the friction between the cutter disc and the step surface, so that the motor can better drive the cutter disc to rotate, reduce energy loss, and improve resource utilization efficiency. At the same time, it can avoid the serious wear caused by the large contact area between the two, which helps to extend the service life of the cutter disc and the guide cylinder; on the other hand, as the contact area between the cutter disc and the step surface decreases, the noise generated by the friction between the two can be reduced, achieving the effect of noise reduction, which helps to improve the user experience. And compared with the traditional production steps of first making an outer slip ring and then adding ribs on the basis of the outer slip ring, when the present application produces an outer slip ring or a guide cylinder, the step surface can be formed on the outer slip ring or the guide cylinder at the same time, thereby simplifying the manufacturing steps of the outer slip ring and helping to reduce production costs.

[0007] In a preferred implementation of a food processor with low operating noise, the bottom surface of the outer slip ring includes a wave area with a wave surface and a non-wave area, and the wave area and the non-wave area are arranged at intervals.

[0008] By including a wave area with a wave surface and a non-wave area on the bottom surface of the outer slip ring, only the wave area of ​​the outer slip ring can contact the step surface, and the non-wave area is suspended above the step surface to achieve separation from the step surface, thereby further reducing the contact area between the step surface and the cutter disc, thereby further reducing the kinetic energy loss and wear caused by the friction between the two, and at the same time further reducing the noise generated by the friction between the two, further improving the noise reduction effect.

[0009] In a preferred implementation of a food processor with low operating noise, the outer slip ring is provided with a convex portion extending radially outward, and the wave area is formed on the bottom surface of the convex portion.

[0010] By providing the outer slip ring with a convex portion extending radially outward, and forming a wave area on the bottom surface of the convex portion, when the motor drives the cutter disc to rotate, only the convex portion can contact and rub against the inner wall of the connecting portion, while the non-wave area can contact neither the step surface nor the inner wall of the connecting portion, thereby reducing the contact area at the two positions. This not only reduces the friction between the step surface and the cutter disc, but also reduces the friction between the outer periphery of the cutter disc and the inner wall of the connecting portion, which helps to further reduce the kinetic energy loss and wear caused by friction, and can also further reduce the noise generated by the friction between the two, further improving the noise reduction effect.

[0011] In a preferred implementation of a food processor with low operating noise, the outer sliding ring is provided with a radially inwardly concave portion, and the non-wave area is formed on the bottom surface of the concave portion.

[0012] By providing a radially inward concave portion on the outer slip ring, the non-wave area is formed on the bottom surface of the concave portion, so that the concave portion can be separated from the step surface and the inner wall of the connecting portion, so that only a part of the cutter disc is in contact with the connecting portion and the step surface, which can not only reduce the friction between the step surface and the cutter disc, but also reduce the friction between the outer periphery of the cutter disc and the inner wall of the connecting portion, which helps to further reduce the kinetic energy loss and wear caused by friction, and at the same time further reduce the noise generated by the friction between the two, further improving the noise reduction effect.

[0013] In a preferred implementation of a food processor with low operating noise, the height of the bottom surface of the non-wavy area from the step surface is higher than the height of the wave surface from the step surface.

[0014] By making the height of the bottom surface of the non-wave area higher than the height of the wave surface from the step surface, only the wave surface can contact the step surface, and the bottom surface of the non-wave area is suspended above the step surface, which effectively avoids the situation where the bottom surface of the non-wave area can also contact the step surface, resulting in an increase in the contact area and an increase in the friction between the cutter disc and the step surface.

[0015] In a preferred implementation of a food processor with low operating noise, the wave surface extends circumferentially along the bottom surface of the outer sliding ring to form an annular wave surface.

[0016] By arranging the wave surface to extend circumferentially along the bottom surface of the outer slip ring to form an annular wave surface, the bottom surface of the outer slip ring is provided with a wave surface. After the outer slip ring contacts the step surface, the outer slip ring can contact the step surface in multiple directions through the wave surface, thereby ensuring the axial support of the step surface to the outer slip ring, avoiding the situation where the entire knife disc has fewer axial support points due to fewer wave surfaces and is easy to tilt, thereby ensuring the position stability of the knife disc and improving the reliability of food processing.

[0017] In a preferred implementation of a food processor with low operating noise, the top surface of the outer slip ring is further provided with a wavy surface, and the knife disc contacts the bottom surface of the main machine through the wavy surface.

[0018] By providing a wavy surface on the top surface of the outer slip ring, the cutter disc contacts the bottom surface of the main machine through the wavy surface, so that if the cutter disc contacts the bottom surface of the main machine when rotating, it can achieve linear contact with the main machine through the wavy surface, effectively avoiding the situation where the contact area between the main machine and the cutter disc is too large, resulting in a large friction between the cutter disc and the main machine, further reducing the kinetic energy loss and wear caused by friction, and at the same time further reducing the noise generated by the friction between the two, further improving the noise reduction effect.

[0019] In a preferred implementation of a food processor with low working noise, the distance H between the highest point of the ridge of the wave surface and the lowest end of the depression satisfies: 0.5≤H≤1mm; or,

[0020] The wave surface includes multiple undulating surfaces, and the distance L between the two ends of a single undulating surface satisfies 10≤L≤30mm, or,

[0021] The angle A between the line connecting the highest bulge and the lowest end of the depression of the wave surface and the horizontal plane satisfies: 1°≤A≤5°.

[0022] By setting the distance H between the highest point of the ridge of the wave surface and the lowest end of the depression to satisfy: 0.5≤H≤1mm, it is avoided that the distance between the highest point of the ridge of the wave surface and the lowest end of the depression is too small, which may cause serious wear of the wave surface after long-term use, resulting in the entire blade disc being able to contact with the step surface and causing excessive friction; at the same time, it is avoided that the distance between the highest point of the ridge of the wave surface and the lowest end of the depression is too large, resulting in a large axial space occupied by the entire blade disc, thereby causing the entire food processor to be too large.

[0023] By setting the distance L between the two ends of a single undulating surface to satisfy 10≤L≤30mm, it is possible to avoid a situation where the distance between the two ends of a single undulating surface is too short, resulting in the need to set multiple undulating surfaces within a unit area of ​​the wave surface, which complicates the manufacturing process and increases the contact area with the step surface; at the same time, it is possible to avoid a situation where the distance between the two ends of a single undulating surface is too large, resulting in a gap between two adjacent undulating surfaces being smaller than the step surface, which makes it easy for food to accumulate there, thereby increasing friction.

[0024] By setting the angle A between the line connecting the highest point of the bulge and the lowest end of the wavy surface and the horizontal plane to satisfy: 1°≤A≤5°, it is avoided that the angle A between the line connecting the highest point of the bulge and the lowest end of the wavy surface and the horizontal plane is too small, resulting in the outer sliding ring directly contacting the step surface and increasing the friction force after the wavy surface is worn for a long time; at the same time, it is avoided that the angle between the line connecting the highest point of the bulge and the lowest end of the wavy surface and the horizontal plane is too large, resulting in excessive protrusion height, resulting in a large space occupied by the entire cutter disc in the axial direction, and thus causing the entire food processor to be too large.

[0025] In a preferred implementation of a food processor with low working noise, a mounting groove adapted to the output shaft of the motor is provided at the center of the cutter disc, and a side of the mounting groove away from the motor is sealed; or,

[0026] A water leakage hole is arranged on one side of the installation slot away from the motor, and the diameter of the water leakage hole is smaller than the diameter of the output shaft of the motor.

[0027] By providing a mounting groove that matches the output shaft of the motor at the center of the cutter disc, and sealing the side of the mounting groove away from the motor, the food in the guide tube cannot splash upward into the mounting groove during food processing, thereby ensuring the cleanliness of the mounting groove and preventing food from splashing into the mounting groove, causing food to accumulate and easily generate odor and be difficult to clean. At the same time, the user can determine the installation direction of the cutter disc according to the direction of the opening of the mounting groove, which helps to improve the assembly efficiency of the cutter disc.

[0028] By providing a leaking hole on the side of the installation slot away from the motor, when the user cleans the cutter disc, the cleaning water in the installation slot can drip to the outside through the leaking hole, avoiding the situation where water accumulates in the installation slot and causes the cutter disc to take a long time to dry. At the same time, the diameter of the leaking hole is set smaller than the output shaft diameter of the motor, so that when the user installs the cutter disc, if the user installs the side of the leaking hole toward the main machine, the output shaft of the motor cannot be inserted into the installation slot, effectively avoiding the user's wrong installation of the cutter disc.

[0029] In a preferred implementation of a food processor with low working noise, a cutting area and a warning area arranged away from the cutting area are provided on the side of the cutter disc facing the main machine, and a warning message is provided in the warning area to warn the user that this side is installed facing the main machine.

[0030] By providing a warning message in the warning area to warn the user that this side should be installed toward the host side, the user can more clearly understand which side needs to be installed toward the host side when installing the cutter disc, which helps to improve the assembly efficiency of the cutter disc.

[0041] In order to more clearly illustrate the overall concept of the present invention, a detailed description is given below in combination with the accompanying drawings by way of examples.

[0042] It should be noted that many specific details are elaborated in the following description to facilitate a full understanding of the present invention. However, the present invention can also be implemented in other ways different from those described herein. Therefore, the protection scope of the present invention is not limited to the specific implementation methods disclosed below.

[0043] like Figures 1 to 7 As shown, the utility model provides a food processing machine with low working noise, comprising a main machine 1 with a built-in motor 2, a cutter disc 3 drivingly connected to the motor 2, and a guide cylinder 4 arranged below the main machine 1, a feeding port for feeding materials is provided on one side of the main machine 1, the main machine 1 is connected above the guide cylinder 4, the guide cylinder 4 and the main machine 1 are connected by snap-fitting, and a pushing rod is provided in the feeding port. When in use, the pushing rod pushes the material downward so that the material can fall more quickly and be sliced ​​or shredded by the cutter disc 3, the top of the guide cylinder 4 has a step portion with a step surface facing upward and a connecting portion 41 extending upward from the step surface to cooperate with the main machine 1, the outer periphery of the cutter disc 3 is covered with an outer slip ring 5, one of the bottom surface and the step surface of the outer slip ring 5 is at least partially provided with a wave surface 53, and the cutter disc 3 contacts the step surface through the wave surface 53.

[0044] The present application covers the outer circumference of the cutter disc 3 with an outer slip ring 5, so that the cutter disc 3 can be protected in the circumferential direction by the outer slip ring 5. After a long period of friction between the outer slip ring 5 and the inner wall and the step surface of the connecting portion 41, if the outer slip ring 5 is severely worn, the user can replace the outer slip ring 5 to ensure the limiting effect on the cutter disc 3, avoiding the need to replace the entire cutter disc 3, which helps to reduce the maintenance cost of the cutter disc 3. At the same time, at least part of one of the bottom surface and the step surface of the outer slip ring 5 is provided with a wavy surface 53, and the cutter disc 3 contacts the step surface through the wavy surface 53, so that when the motor 2 drives the cutter disc 3 to rotate, the cutter disc 3 contacts the step surface through the wavy surface 53, so that part of the bottom wall of the cutter disc 3 cannot contact the step surface, thereby reducing the contact area between the entire cutter disc 3 and the step surface. On the one hand, it can reduce the friction between the cutter disc 3 and the step surface, so that the motor 2 can better drive the cutter disc 3 to rotate, reduce energy loss, and improve resource utilization efficiency. At the same time, it can avoid severe wear caused by the large contact area between the two, which helps to extend the service life of the cutter disc 3 and the guide cylinder 4; on the other hand, as the contact area between the cutter disc 3 and the step surface decreases, the noise generated by the friction between the two can be reduced, achieving the effect of noise reduction, which helps to improve the user experience. Furthermore, compared to the conventional production steps of first manufacturing the outer slip ring 5 and then adding convex ribs on the basis of the outer slip ring 5, in the present application, when producing the outer slip ring 5 or the guide cylinder 4, the step surface can be formed on the outer slip ring 5 or the guide cylinder 4 at the same time, thereby simplifying the manufacturing steps of the outer slip ring 5 and helping to reduce production costs.

[0045] It should be noted that the present application does not specifically limit the materials of the cutter disc 3 and the outer slip ring 5. Preferably, the cutter disc 3 is made of metal, and the outer slip ring 5 is made of plastic, which further reduces the friction between the outer slip ring 5 and the step surface. At the same time, if the outer slip ring 5 is severely worn or even damaged after long-term use, the user can remove the outer slip ring 5 and replace it to reduce maintenance costs. At the same time, there is no limitation on the connection method between the cutter disc 3 and the outer slip ring 5. The two can be detachably connected. Preferably, the outer slip ring 5 is integrally injection-molded on the outer periphery of the cutter disc 3 to improve the stability of the connection between the two.

[0046] It should be noted that the present application does not specifically limit the location of the wave surface 53, which can be set on a step surface. As a preferred embodiment of the present application, the bottom surface of the outer slip ring 5 includes a wave area with a wave surface 53 and a non-wave area, and the wave area and the non-wave area are arranged at intervals. It should be noted that the present application does not specifically limit the structure of the bottom surface of the non-wave area, which can be a plane or an inclined surface, which will not be repeated here.

[0047] By including a wave area with a wave surface 53 and a non-wave area on the bottom surface of the outer slip ring 5, only the wave area of ​​the outer slip ring 5 can contact the step surface, and the non-wave area is suspended above the step surface to achieve separation from the step surface, thereby further reducing the contact area between the step surface and the cutter disc 3, thereby further reducing the kinetic energy loss and wear caused by friction between the two, and at the same time further reducing the noise generated by the friction between the two, further improving the noise reduction effect.

[0048] As a preferred embodiment of this embodiment, Figure 4 As shown, the outer slip ring 5 is provided with a convex portion 52 extending radially outward, and the wave area is formed on the bottom surface of the convex portion 52 .

[0049] By providing the outer slip ring 5 with a radially outwardly extending protrusion 52, and forming a wave area on the bottom surface of the protrusion 52, when the motor 2 drives the cutter disc 3 to rotate, only the protrusion 52 can contact and rub against the inner wall of the connecting portion 41, and the non-wave area can neither contact the step surface nor the inner wall of the connecting portion 41, thereby achieving a reduction in the contact area at the two positions, which can not only reduce the friction between the step surface and the cutter disc 3, but also reduce the friction between the outer periphery of the cutter disc 3 and the inner wall of the connecting portion 41, which helps to further reduce the kinetic energy loss and wear caused by friction, and can also further reduce the noise generated by the friction between the two, further improving the noise reduction effect.

[0050] As a preferred embodiment of this embodiment, Figure 4 As shown, the outer slip ring 5 is provided with a radially inwardly concave portion 51 , and the non-wave area is formed on the bottom surface of the concave portion 51 .

[0051] By providing a radially inward recess 51 on the outer slip ring 5, the non-wave area is formed on the bottom surface of the recess 51, so that the recess 51 can be separated from the step surface and the inner wall of the connecting portion 41, so that only a part of the cutter disc 3 is in contact with the connecting portion 41 and the step surface, which can not only reduce the friction between the step surface and the cutter disc 3, but also reduce the friction between the outer periphery of the cutter disc 3 and the inner wall of the connecting portion 41, which helps to further reduce the kinetic energy loss and wear caused by friction, and at the same time can further reduce the noise generated by the friction between the two, further improving the noise reduction effect.

[0052] As a preference under this embodiment, the height of the bottom surface of the non-wavy area from the step surface is higher than the height of the wavy surface 53 from the step surface.

[0053] By making the height of the bottom surface of the non-wave area higher than the height of the wave surface 53 from the step surface, only the wave surface 53 can contact the step surface, while the bottom surface of the non-wave area is suspended above the step surface, effectively avoiding the situation where the bottom surface of the non-wave area can also contact the step surface, resulting in an increase in the contact area and an increase in the friction between the cutter disc 3 and the step surface.

[0054] As another preferred embodiment of the present application, the wave surface 53 extends circumferentially along the bottom surface of the outer slip ring 5 to form an annular wave surface 53 .

[0055] By setting the wave surface 53 to extend circumferentially along the bottom surface of the outer slip ring 5 to form an annular wave surface 53, the bottom surface of the outer slip ring 5 is provided with a wave surface 53. After the outer slip ring 5 contacts the step surface, the outer slip ring 5 can contact the step surface in multiple directions through the wave surface 53, thereby ensuring the axial support of the step surface to the outer slip ring 5, avoiding the situation where the wave surface 53 is set less, resulting in fewer axial support points of the entire knife disc 3 and making it easy to tilt, thereby ensuring the position stability of the knife disc 3 and improving the reliability of food processing.

[0056] As a preferred implementation of the present application, Figure 6 , Figure 7 As shown, the top surface of the outer slip ring 5 is further provided with a wave surface 53 , and the cutter head 3 contacts the bottom surface of the main machine 1 through the wave surface 53 .

[0057] By providing a wavy surface 53 on the top surface of the outer slip ring 5, the cutter disc 3 contacts the bottom surface of the main machine 1 through the wavy surface 53, so that if the cutter disc 3 contacts the bottom surface of the main machine 1 when rotating, it can achieve linear contact with the bottom surface of the main machine 1 through the wavy surface 53, effectively avoiding the situation where the contact area between the main machine 1 and the cutter disc 3 is too large, resulting in a large friction force between the cutter disc 3 and the main machine 1, further reducing the kinetic energy loss and wear caused by friction, and at the same time further reducing the noise generated by the friction between the two, further improving the noise reduction effect.

[0058] It should be noted that the present application does not specifically limit the size of the wave surface 53. As a preferred embodiment of the present application, Figure 7 As shown, the distance H between the highest point of the ridge of the wave surface 53 and the lowest end of the depression satisfies: 0.5≤H≤1mm.

[0059] By setting the distance H between the highest point of the ridge of the wave surface 53 and the lowest end of the depression to satisfy: 0.5≤H≤1mm, it is avoided that the distance between the highest point of the ridge of the wave surface 53 and the lowest end of the depression is too small, which may cause the wave surface 53 to be severely worn after long-term use, causing the entire blade disc 3 to contact with the step surface and cause excessive friction; at the same time, it is avoided that the distance between the highest point of the ridge of the wave surface 53 and the lowest end of the depression is too large, causing the entire blade disc 3 to occupy a large axial space and thus causing the entire food processor to be too large.

[0060] As a preferred implementation of the present application, Figure 7 As shown, the wave surface 53 includes a plurality of undulating surfaces, and the distance L between the two ends of a single undulating surface satisfies 10≤L≤30 mm.

[0061] By setting the distance L between the two ends of a single undulating surface to satisfy 10≤L≤30mm, it is possible to avoid the situation where the distance between the two ends of a single undulating surface is too short, resulting in the need to set multiple undulating surfaces within a unit area of ​​the wave surface 53, which makes the manufacturing process complicated and increases the contact area with the step surface; at the same time, it is possible to avoid the situation where the distance between the two ends of a single undulating surface is too large, resulting in the gap between two adjacent undulating surfaces being smaller than the step surface, which makes it easy for food to accumulate there, thereby increasing friction.

[0062] As a preferred implementation of the present application, Figure 7 As shown, the angle A between the line connecting the highest point of the ridge and the lowest end of the depression of the wave surface 53 and the horizontal plane satisfies: 1°≤A≤5°.

[0063] By setting the angle A between the line connecting the highest point of the ridge of the wave surface 53 and the lowest end of the depression and the horizontal plane to satisfy: 1°≤A≤5°, it is avoided that the angle A between the line connecting the highest point of the ridge of the wave surface 53 and the lowest end of the depression and the horizontal plane is too small, which leads to the outer slip ring 5 directly contacting the step surface and causing increased friction after the wave surface 53 is worn for a long time; at the same time, it is avoided that the angle between the line connecting the highest point of the ridge of the wave surface 53 and the lowest end of the depression and the horizontal plane is too large, which leads to the protrusion height being too large, resulting in a large axial space occupied by the entire knife disc 3, and thus causing the entire food processor to be too large.

[0064] As a preferred implementation of the present application, Figure 5 As shown, a mounting groove 31 adapted to the output shaft of the motor 2 is provided at the center of the cutter head 3, and a side of the mounting groove 31 away from the motor 2 is sealed.

[0065] By providing a mounting groove 31 adapted to the output shaft of the motor 2 at the center of the cutter disc 3, and sealing the side of the mounting groove 31 away from the motor 2, the food in the guide cylinder 4 cannot splash upward into the mounting groove 31 during food processing, thereby ensuring the cleanliness of the mounting groove 31 and preventing food from splashing into the mounting groove 31, which may cause food to accumulate and easily generate odor and be difficult to clean. At the same time, the user can determine the installation direction of the cutter disc 3 according to the direction of the opening of the mounting groove 31, which helps to improve the assembly efficiency of the cutter disc 3.

[0066] Of course, the mounting groove 31 in the present application is not limited to the above setting, and a water leakage hole may be provided on the side of the mounting groove 31 away from the motor 2, and the diameter of the water leakage hole is smaller than the output shaft diameter of the motor 2.

[0067] By providing a leaking hole on the side of the installation slot 31 away from the motor 2, when the user cleans the cutter disc 3, the cleaning water in the installation slot 31 can drip to the outside through the leaking hole, avoiding the situation where water accumulates in the installation slot 31 and causes the cutter disc 3 to take a long time to dry. At the same time, the diameter of the leaking hole is smaller than the diameter of the output shaft of the motor 2, so that when the user installs the cutter disc 3, if the user installs the side of the leaking hole toward the side of the main machine 1, the output shaft of the motor 2 cannot be inserted into the installation slot, effectively avoiding the user's wrong installation of the cutter disc 3.

[0068] As a preferred implementation of the present application, Figure 4 As shown, the side of the cutter disc 3 facing the main machine 1 is provided with a cutting area and a warning area 6 set away from the cutting area. The warning area 6 is provided with a warning word for warning the user that this side is installed toward the main machine 1. Specifically, a warning word is engraved in the warning area 6 with this side facing the main machine 1.

[0069] By providing a warning message in the warning area 6 to warn the user that this side should be installed toward the main unit 1, the user can more clearly understand which side needs to be installed toward the main unit 1 when installing the cutter disc 3, which helps to improve the assembly efficiency of the cutter disc 3.

[0070] It should be noted that the transmission cooperation with the motor 2 in the present application is not limited to the above-mentioned guide cylinder 4, which can also be replaced by a condiment bowl, a minced meat bowl or a supplementary food bowl, etc., and different crushing devices are provided in different bowls to be connected to the motor 2 transmission.

[0071] The technical solution protected by the present utility model is not limited to the above-mentioned embodiments. It should be pointed out that the combination of the technical solution of any embodiment with the technical solution of one or more other embodiments is within the protection scope of the present utility model.
