Description

Technical Field

[0001] The utility model relates to the field of food processing machines, in particular to a food processing machine with an optimized structure. Background Art

[0002] At present, in order to improve the crushing effect of ingredients, the blending cups of food processors on the market are generally provided with spoiler ribs on the inner wall of the blending cup. The spoiler ribs extend along the axial direction of the blending cup to a certain length, and the spacing between adjacent spoiler ribs is large, so the number of spoiler ribs is small and the sites where turbulence can be formed are limited. Ingredients are only cut and crushed near the spoiler ribs, resulting in insufficient crushing. If the crushing effect is improved by increasing the motor power, the working noise of the machine will be increased.

[0003] Furthermore, for the existing spoiler rib structure, the inventors have found that it is difficult to ensure the crushing effect when the height of the spoiler rib is lower than 5 mm. Therefore, in order to ensure the crushing effect, the existing spoiler ribs are set higher, generally not lower than 5 mm. The higher the height of the spoiler rib, the better the turbulent flow effect, and thus the better the crushing effect. However, at the same time, higher spoiler ribs are more difficult to process. On the one hand, it increases the processing difficulty. On the other hand, the existing spoiler ribs are generally stamped directly on the steel cup. When the spoiler rib is higher, the thickness of the rib part will be thin, and there is a risk of breaking, which makes it difficult to ensure the yield rate. Utility Model Content

[0004] The utility model provides a food processor with optimized structure, aiming to solve the technical problems that the existing stirring cup with spoiler ribs needs to be provided with higher spoiler ribs to ensure the crushing effect, but this leads to processing difficulties, low yield and high pulping noise.

[0005] The utility model discloses a structurally optimized food processor, comprising a cup body, a crushing blade arranged in the cup body, and a motor driving the crushing blade. The inner wall surface of the cup body is provided with a convex hull distribution area, the convex hull distribution area extends along the circumference of the cup body and has a plurality of convex hulls distributed in an array, the upper edge of the convex hull distribution area is not lower than the maximum pulping capacity, the lower edge of the convex hull distribution area is not higher than the minimum pulping capacity, the radial inward protrusion height of a single convex hull is 1.2mm-2.5mm, and the projected area of ​​a single convex hull on the inner wall surface of the cup body is 40mm 2 -180mm 2 .

[0006] The structurally optimized food processing machine of the present invention also has the following additional technical features:

[0007] The distance between the upper edge of the convex rim at the highest point of the cup body and the cup mouth is 5mm-10mm 。

[0008] The distance between the lower edge of the convex hull located at the lowest point of the cup body and the bottom wall of the cup body is not less than 3 mm, and not greater than the distance from the tip of the crushing knife to the bottom wall of the cup body.

[0009] Convex hull offset setting between adjacent rows or adjacent columns.

[0010] The gap between two adjacent convex hulls is 0.5mm-20mm.

[0011] The cup body includes an axially penetrating peripheral wall and a bottom wall arranged at the bottom opening of the peripheral wall. The peripheral wall is formed by rolling a plate body punched with multiple convex humps. The bottom wall is flat or bowl-shaped. The bottom wall and the peripheral wall are welded together.

[0012] The convex hull is conical, and the inclination angle of the upper side surface of the convex hull is not less than the inclination angle of the lower side surface of the convex hull.

[0013] The top surface of the convex hull is a plane, and the equivalent diameter of the plane is 2mm-5mm; or, the top surface of the convex hull is a curved surface, and the radius corresponding to the curved surface is 2.5mm-6mm.

[0014] The inner wall surface of the cup body has a water level marking area without a convex hull, the water level marking area is provided with a water level line, and multiple convex hulls are arranged around the water level marking area; or, the inner wall surface of the cup body has a water level marking area without a convex hull, the water level marking area extends from the cup mouth to the cup bottom, the water level marking area is provided with a water level line, and the two ends of the convex hull distribution area are separated on both sides by the water level marking area.

[0015] The food processor includes a head arranged above the cup body, and the motor is arranged in the head, or the motor is arranged below the cup body and connected to the cup body as a whole, or the food processor includes a main body, the motor is arranged in the main body, and the cup body is detachably mounted on the main body.

[0016] Due to the adoption of the above technical solution, the utility model has the following beneficial effects:

[0017] 1. The food processing machine with optimized structure of the present invention replaces conventional spoiler ribs with smaller convex hulls. A larger number of convex hulls can be set on the same cup surface, thereby forming more spoiler sites. The liquid flow forms turbulence at more spoiler sites, which is conducive to making the material constantly contact with the crushing blade, thereby improving the crushing efficiency. In addition, the overall turbulence of the liquid flow is improved, which is conducive to achieving a better crushing effect. On this basis, the height of a single convex hull is smaller than that of a conventional spoiler rib, making the convex hull easy to process during stamping, and there is no need to worry about large deformation of the cup body. Avoid breakage and ensure the yield of the cup body; in addition, according to the inventor's research, the higher the height of the spoiler rib, the more rotating liquid flow can be blocked, the turbulence can be increased, and thus the crushing effect can be improved, but at the same time, the spoiler rib bears more impact of the liquid flow, resulting in increased noise; and the present application adopts a large number of convex hulls, and more gaps are formed between the convex hulls. These gaps can disperse the liquid flow, so that the impact of the liquid flow on the convex hulls is greatly reduced, thereby effectively reducing the noise; in addition, concave portions are formed between adjacent convex hulls, and the uneven design formed with the convex hulls is conducive to absorbing more noise, thereby improving the overall noise reduction performance.

[0018] 2. Under normal circumstances, there should be a certain distance between the upper edge of the convex bulge at the highest point of the cup body and the cup mouth. The distance can be set to 5mm-10mm. The highest liquid level does not exceed the highest convex bulge, so that an overflow-proof space is formed between the upper edge of the highest convex bulge and the cup mouth. If the above distance is too small, the overflow-proof space will be insufficient, which will increase the risk of slurry overflow. If the distance is too large, the number of convex bulges will be reduced, which will affect the crushing effect and reduce the space utilization of the cup body.

[0019] 3. When the convex humps are only provided on the side walls of the cup body, the distance between the lower edge of the convex humps located at the lowest point of the cup body and the bottom wall of the cup body is not less than 3 mm, so as to avoid the convex humps being set too low and difficult to clean, thereby increasing the difficulty of cleaning; in addition, the above distance is not greater than the distance between the tip of the crushing knife and the bottom wall of the cup body, so that when the slurry volume is small and the liquid level is low (for example, the liquid level just covers the crushing knife), it can still be ensured that there are available convex humps to disturb the flow, thereby ensuring the crushing effect.

[0020] 4. Multiple convex hulls are distributed in an array. The specific distribution form can be either an aligned arrangement of convex hulls between adjacent rows or columns, or a staggered arrangement of convex hulls between adjacent rows or columns. Regardless of the arrangement, a large number of convex hulls can be set, which not only ensures a dense distribution of convex hulls but also visually uncluttered, thus having a certain aesthetic appeal.

[0021] 5. By limiting the gap between two adjacent convex hulls to 0.5mm-20mm, it is possible to avoid the difficulty of forming the convex hulls due to the gap being too small, which increases the difficulty of processing. At the same time, it is also possible to avoid the gap being too large, which reduces the number of convex hulls in the limited area of ​​the cup body and leads to insufficient crushing.

[0022] 6. The cup body forming process of the present application can be to first punch out a predetermined number of bulges on a flat plate body, then form the peripheral wall of the cup body by curling the plate body, and then weld the bottom wall. The bulge punching is easy to do and convenient for processing. Moreover, the rib height of the previous stainless steel cup is high, resulting in a thin thickness at the rib position and a risk of breaking. The bulge punching height of the present application is low, which can ensure the thickness of the rib position, which is beneficial to enhance the overall strength of the cup body and improve durability.

[0023] 7. When cleaning the convex hull, the lower side of the convex hull is not easy to see and is easily in the blind spot. In order to facilitate the cleaning of the convex hull, the inclination angle of the lower side of the convex hull can be set to be relatively small, which is conducive to the brush cleaning the lower side of the convex hull and avoids the situation where the brush has to be held horizontally to brush when the inclination angle of the lower side is large, resulting in cleaning difficulties. The inclination angle of the upper side of the convex hull only needs to be not less than the inclination angle of the lower side of the convex hull, because the upper side of the convex hull is within the sight range and is relatively easy to clean.

[0024] 8. By setting the inwardly protruding top surface of the convex hull as a surface structure rather than a point structure, on the one hand, it is easy to clean, and on the other hand, it is conducive to the circulation of liquid through the top surface of the convex hull, thereby improving the fluidity of the liquid and thus improving the crushing effect; the top surface of the convex hull should not be too large, so as not to make the size of a single convex hull larger and reduce the number of convex hulls that can be set, resulting in insufficient crushing; the top surface of the convex hull should not be too small, so as not to be too sharp and easily hit the user when cleaning the convex hull and hurt the user.

[0025] 9. A water level marking area is provided on the inner wall surface of the cup body in the area where no convex hull is provided. A water level line is provided in the water level marking area so that the user can add the required amount of water according to the water level line to meet the processing requirements of slurries of different capacities. On this basis, the distribution of the convex hulls can be arranged around the water level marking area or on both sides of the water level marking area, which has high flexibility and improves space utilization while making the overall distribution orderly and clear, easy for users to view and beautiful in appearance.

[0040] like Figures 1 to 4 As shown, the present application provides a structurally optimized food processing machine, comprising a cup body 10, a crushing blade 11 disposed in the cup body 10, and a motor 12 for driving the crushing blade 11. The inner wall surface of the cup body 10 is provided with a convex hull distribution area, which extends along the circumference of the cup body 10 and has a plurality of convex hulls 13 distributed in an array. The upper edge of the convex hull distribution area is not lower than the maximum pulping capacity, and the lower edge of the convex hull distribution area is not higher than the minimum pulping capacity. The radially inward protrusion height H of a single convex hull 13 is 1.2 mm to 2.5 mm, and the projected area of ​​a single convex hull 13 on the inner wall surface of the cup body 10 is 40 mm. 2 -180mm 2 .

[0041] The food processor of the present invention with optimized structure replaces the conventional spoiler ribs with smaller convex bumps 13. A larger number of convex bumps 13 can be set on the surface of the same cup body 10, thereby forming more spoiler sites. The liquid flow forms turbulence at more spoiler sites, which is beneficial for the material to be in continuous contact with the crushing knife, thereby improving the crushing efficiency, and the overall turbulence of the liquid flow is improved, which is beneficial for achieving a better crushing effect. On this basis, the height of a single convex bump 13 is smaller than that of a conventional spoiler rib, so that the convex bump 13 is easy to process during stamping, and there is no need to worry about large deformation of the cup body, which can avoid Avoiding breakage, ensuring the yield rate of the cup body; in addition, according to the inventor's research, the higher the height of the spoiler ribs, the more they can block the rotating liquid flow, increasing turbulence and thus improving the crushing effect. However, at the same time, the spoiler ribs are subjected to more impact from the liquid flow, resulting in increased noise. The present application, however, utilizes a large number of convex bumps 13, creating a large number of gaps between the convex bumps 13. These gaps can disperse the liquid flow, greatly reducing the impact of the liquid flow on the convex bumps 13, thereby effectively reducing noise. In addition, the concave portions formed between adjacent convex bumps 13, together with the convex bumps 13, form an uneven design that helps absorb more noise, thereby improving the overall noise reduction performance. Furthermore, the convex bumps 13 are relatively low in height, making them easier to clean, providing users with convenient cleaning.

[0042] Specifically, the food processor can be a soy milk maker or a wall breaking machine. The use of the cup body 10 as described above can improve the quality and taste of the slurry. When sufficient turbulence is achieved and sufficient crushing is achieved, it is beneficial to reduce the residue discharge rate, thereby eliminating the filtering step and making the taste of the slurry more delicate.

[0043] The convex hull distribution area can cover a part of the circumferential area of ​​the cup body, or it can cover the entire circumferential area, depending on the required number of hulls. By limiting the position of the upper and lower edges of the hull distribution area, the hulls can ensure effective flow disturbance within the allowable pulping capacity, thereby ensuring the crushing effect. The hull 13 is different from the previous long strip of flow-disturbing ribs. The projection shape of the hull 13 on the inner wall surface of the cup body 10 can be circular or approximately circular (for example, polygonal). The equivalent diameter of the projection of a single hull 13 is about 7.2mm-15mm, which greatly reduces the area occupied by a single hull 13. Figure 3 As shown, a large number of convex humps 13 can be set on the limited surface of the cup body 10, dozens or even hundreds of them, which is far more than the limited number of spoiler ribs currently available, thereby achieving sufficient spoiler flow and improving the crushing effect. The projected area of ​​a single convex hump 13 on the inner wall surface of the cup body 10 is 40mm 2 -180mm 2 The projected area can be obtained based on the equivalent diameter. When the projected area is less than 40mm 2 When the projection area is larger than 180mm, the convex hull 13 is difficult to form and the processing difficulty will be increased.2 When the surface of the cup body 10 is limited, the total number of convex hulls 13 will be reduced, which may lead to insufficient crushing.

[0044] The height of the conventional spoiler ribs is generally not less than 5mm. Although it can improve the crushing effect to a certain extent (but the slag discharge rate is still greater than 20%, and the user may still need to perform manual filtering), the noise is relatively loud (generally greater than 70dB). The height H of the convex hull 13 of the present application is preferably 1.2mm-2.5mm. Figure 2 As shown, the height of the convex ridge 13 refers to the height of the convex ridge 13 extending away from the inner wall surface of the cup body 10. Compared with the height of conventional spoiler ribs, it is reduced, which can effectively reduce the crushing noise. Using the cup body 10 of the present application with the above-mentioned convex ridge 13, tests were conducted under the conditions of a pulping capacity of 600mL and a soybean amount of 42.8g. As shown in Table 1 below:

[0045] As the height of the convex hump 13 increases, the slag discharge rate decreases, which is conducive to making the slurry taste more delicate, but the noise also increases. In order to take into account both the crushing effect and noise reduction, the slag discharge rate is controlled below 20% (which can save the user filtering step and improve the user experience), and the noise is less than 70dB. The height of the convex hump 13 can be selected to be 1.2mm-2.5mm, which can improve the overall performance of the food processor.

[0046] Table 1. Comparison of noise and slag discharge rate at different convex hull heights

[0047] Serial number Convex height (mm) Noise (dB) Slag discharge rate (%) 1 0.8 63.3 24.1 2 1.2 64.1 19.7 3 1.4 64.5 18.3 4 1.6 65.5 15.6 5 1.8 66.8 13.4 6 2.0 67.9 12.3 7 2.2 68.5 10.9 8 2.3 69.2 9.5 9 2.5 69.8 8.1 10 2.8 72.8 7.7

[0048] As a preferred embodiment, Figure 4 As shown, the distance H1 between the upper edge of the convex hull 13 at the highest point of the cup body 10 and the cup mouth is 5mm-10mm.

[0049] It is understandable that when the user adds water, the maximum liquid level is generally controlled to just cover the highest bulge 13, that is, the space from the upper edge of the highest bulge 13 to the cup mouth is used as an anti-overflow space to avoid overflow during the pulping process, thereby avoiding safety or hygiene problems. When the distance between the upper edge of the bulge 13 at the highest point of the cup body 10 and the cup mouth is less than 5mm, the anti-overflow space is obviously insufficient, which will increase the risk of overflow and cause safety problems; on the contrary, when the distance between the upper edge of the bulge 13 at the highest point of the cup body 10 and the cup mouth is greater than 10mm, the number of bulges 13 will be reduced, which will affect the crushing effect and reduce the space utilization of the cup body 10. Therefore, the distance H1 between the upper edge of the bulge 13 at the highest point of the cup body 10 and the cup mouth can be set to values ​​such as 5mm, 6mm, 7mm, 8mm, 9mm, 10mm, etc.

[0050] The convex hump 13 of the present application can be provided only on the inner sidewall of the cup body 10, or a portion of the convex hump 13 can be provided on the inner sidewall of the cup body 10 and a portion of the convex hump 13 can be provided on the inner bottom wall of the cup body 10, as required. When the convex hump 13 is provided only on the inner sidewall of the cup body 10, the cleaning and crushing problems of the cup body 10 can be improved by optimizing the lowest position of the convex hump 13.

[0051] As a preferred embodiment, Figure 4 As shown, the distance H2 between the lower edge of the convex 13 located at the lowest point of the cup body 10 and the bottom wall of the cup body 10 is not less than 3 mm and not greater than the distance from the tip of the crushing knife 11 to the bottom wall of the cup body 10 .

[0052] Specifically, when the distance between the lower edge of the bulge 13 at the lowest point of the cup body 10 and the bottom wall of the cup body 10 is less than 3 mm, on the one hand, the bulge 13 is too low, and it is not easy for the user to reach the lowest bulge 13 when cleaning the cup body 10, resulting in cleaning difficulties, or the user needs to use a longer brush for cleaning, and it is difficult to apply force on the lowest bulge 13 and it is easy to not clean thoroughly. On the other hand, the gap between the bulge 13 and the bottom wall of the cup body 10 is too small to easily hide residue, and this position is also not easy to clean, which will affect the cleanliness of the cup body 10 over time.

[0053] In some scenarios, users want to make very small-volume drinks, for example, the amount of water just covers the crushing blade 11. If no turbulent flow structure is provided in the height section from the highest point of the crushing blade 11 to the bottom wall of the cup body 10, the crushing effect will inevitably be reduced. Therefore, the distance between the lower edge of the convex 13 located at the lowest point of the cup body 10 and the bottom wall of the cup body 10 can be limited to no more than the distance from the tip of the crushing blade 11 to the bottom wall of the cup body 10. Then, even when making the above-mentioned small-volume drinks, the lower convex 13 can play a turbulent role, thereby ensuring the crushing effect.

[0054] The convex hulls 13 of the present application are arranged in an array, which can improve the aesthetics compared to the random and disorderly arrangement of multiple convex hulls 13. For example, in one embodiment, Figure 1 As shown, the convex hulls 13 are distributed in multiple rows and columns, and the convex hulls 13 between adjacent rows and adjacent columns are aligned. This arrangement can greatly reduce the difficulty of processing. In another embodiment, as Figure 4 As shown, the convex hulls 13 between adjacent rows are staggered, and this arrangement can be used when it is not necessary to arrange the convex hulls 13 more densely. Alternatively, in other embodiments, the convex hulls 13 between adjacent columns are staggered, and this arrangement can also be used when it is not necessary to arrange the convex hulls 13 too densely.

[0055] Typically, to facilitate user control of the amount of water added, a water level line 141 is provided on the cup body 10 for reference. Users can add water according to desired volume requirements, more accurately matching the amount of ingredients to produce a drink with a good taste. The convex bump 13 of the present application occupies a majority of the sidewall surface of the cup body 10. On this basis, a reasonable layout can simultaneously meet the visual requirements of the water level line 141.

[0056] In one embodiment, Figure 4 As shown, the inner wall surface of the cup body 10 has a water level marking area 14 without a convex bump 13 , the water level marking area 14 is provided with a water level line 141 , and a plurality of convex bumps 13 are arranged around the water level marking area 14 .

[0057] like Figure 4 As shown, in this embodiment, the convex hull distribution area substantially covers the entire circumference of the cup body, requiring only a small space for the water level marking area 14, which facilitates expanding the distribution range of the convex hull 13. The water level lines 141 include at least a maximum water level line 141 and a minimum water level line 141. Of course, to meet the user's various capacity requirements, the water level lines 141 also include multiple intermediate water level lines 141 located between the maximum water level line 141 and the minimum water level line 141. Capacity markings are provided near each water level line 141, allowing the user to add water according to the capacity markings, achieving precise control of the water volume.

[0058] In another embodiment, Figure 1 As shown, the inner wall surface of the cup body 10 has a water level marking area 14 without a convex hull 13. The water level marking area 14 extends from the cup mouth to the cup bottom. The water level marking area 14 is provided with a water level line 141. The two ends of the convex hull distribution area are separated on both sides by the water level marking area 14.

[0059] like Figure 1 As shown, in this embodiment, the convex hull distribution area covers most of the area of ​​the cup body along the circumference. The water level marking area 14 is, for example, provided in the middle of the cup body 10 on the side facing the user. The convex hulls 13 are distributed on the left and right sides of the water level marking area 14. In addition to the water level marking area 14, the other areas of the cup body 10 along the circumference are all provided with convex hulls 13. The water level marking area 14 of this embodiment has a large distribution range and is more clearly divided from the convex hull 13, and the display effect is more intuitive and clear. The water level line 141 includes at least a maximum water level line 141 and a minimum water level line 141. Of course, in order to meet more capacity requirements of the user, the water level line 141 also includes multiple intermediate water level lines 141 between the maximum water level line 141 and the minimum water level line 141, and a capacity mark is provided near each water level line 141, so that the user can add water according to the capacity mark to achieve precise control of the water volume.

[0060] On the premise that the convex hulls 13 are distributed in an array, the gap between two adjacent convex hulls 13 is 0.5mm-20mm, which can avoid the gap being too small, which makes it difficult to form the convex hulls 13 and increases the difficulty of processing. At the same time, it can also avoid the gap being too large, which reduces the number of convex hulls 13 in the limited area of ​​the cup body 10 and leads to insufficient crushing.

[0061] The cup body 10 of the present application can be either a glass cup or a stainless steel cup. The conventional process for stainless steel cups is stretching-punching, while the process for the stainless steel cup body 10 of the present application is punching-curling-welding-polishing. That is, a predetermined number of convex bumps 13 are first punched out on a flat plate, and then the plate is curled to form the peripheral wall of the cup body 10, and then the bottom wall is welded. The bottom wall can be flat or bowl-shaped. The ribs of the previous stainless steel cups were punched to a high height, resulting in a thin thickness at the ribs and a risk of breaking. The convex bumps 13 of the present application are punched to a low height, which can ensure the thickness of the ribs, thereby enhancing the overall strength of the cup body 10 and improving its durability.

[0062] As a preferred embodiment, the convex hull 13 is conical, and the inclination angle of the upper side surface 131 of the convex hull is not less than the inclination angle of the lower side surface 132 of the convex hull.

[0063] like Figure 2 As shown, the horizontal plane where the highest point of the convex hull 13 is located is used as the dividing line. The upper side surface 131 of the convex hull is located above the horizontal plane, and the lower side surface 132 of the convex hull is located below the horizontal plane. It can be understood that when cleaning the convex hull 13, the lower side surface 132 of the convex hull is not easy to be seen and is easily in a blind spot. In order to facilitate the cleaning of the convex hull 13, the inclination angle of the lower side surface 132 of the convex hull can be set to be relatively small, which is conducive to the brush cleaning the lower side surface 132 of the convex hull and avoids the situation where the brush has to be held horizontally to brush when the inclination angle of the lower side surface is large, resulting in difficulty in cleaning. The inclination angle of the upper side surface 131 of the convex hull only needs to be not less than the inclination angle of the lower side surface 132 of the convex hull, because the upper side surface 131 of the convex hull is within the sight range and is relatively easy to clean. Figure 2 As shown, the angle between the upper side surface 131 of the convex hull and the inner wall surface of the cup body 10 is α, and the angle between the lower side surface 132 of the convex hull and the inner wall surface of the cup body 10 is β, β≤α.

[0064] Furthermore, by configuring the inwardly protruding top surface 133 of the convex hump 13 as a flat surface rather than a point structure, cleaning is facilitated and liquid circulation is facilitated through the top surface 133 of the convex hump 13, thereby enhancing liquid fluidity and thus improving the crushing effect. The top surface 133 of the convex hump 13 should not be too large, as this would reduce the number of convex hump 13s that can be provided and lead to insufficient crushing. The top surface 133 of the convex hump 13 should also not be too small, as this would be too sharp and could easily cause pain to the user when cleaning the convex hump 13. The top surface 133 of the convex hump 13 refers to the surface of the convex hump 13 closest to the central axis of the cup body.

[0065] In one embodiment, Figure 2 As shown, the top surface 133 of the convex hull 13 is a plane with an equivalent diameter of 2mm-5mm. The plane is the highest position of the convex hull 13. Since the height of the plane is consistent, it is easier to control during stamping, which helps to reduce the difficulty of processing.

[0066] In one embodiment, the top surface 133 of the convex hump 13 is an arc surface, and the radius of the arc surface is 2.5mm-6mm. The arc surface is conducive to making the convex hump 13 transition more smoothly from the top to the root, so that the surface of the convex hump 13 is easier to clean.

[0067] Based on the above embodiment, the food processing machine of the present application can be a soymilk machine or a wall-breaking machine. Common soymilk machines or wall-breaking machines can adopt the above-mentioned cup body 10 to improve the quality and taste of the slurry, while improving the noise reduction performance of the machine and enhancing the user experience.

[0068] The food processor can be a type with a head disposed above the cup body 10, and correspondingly, the motor 12 is disposed in the head; or the food processor can be an integrated structure, such as Figure 1 or Figure 4 As shown, the motor 12 is connected to the bottom of the cup body 10, which eliminates the need for users to frequently operate the heavier machine head, making it more convenient to use. Alternatively, the food processor can be a type in which the cup body 10 is separated from the main body, and the motor 12 is arranged in the main body. The structure of the cup body 10 is relatively simple, small and light, making it more convenient for users to pick up for pouring and cleaning.
