Abstract
Description
Technical Field
[0001] This utility model relates to the field of household appliance technology, specifically to a food processing machine that operates stably. Background Technology
[0002] Existing food processors, such as meat grinders and dough mixers, typically consist of a cup with a built-in mixing element and a main unit detachably connected to the cup. The main unit contains a motor that drives the mixing element. When using the food processor, the user places the food into the cup, and the mixing element rotates under the motor's power to process the food. However, existing food processors are limited in function, only capable of processing one type or similar food. To process different foods, users need to purchase different types of food processors; for example, a meat grinder is needed for grinding meat, and a dough mixer is needed for kneading dough. This results in high operating costs and requires separate storage for different food processors, leading to a poor user experience.
[0003] To address the aforementioned issues, existing technology discloses a nested inner and outer cup design. The inner and outer cups are used for processing different ingredients; for example, the inner cup is used for kneading dough, while the outer cup is used for mincing meat. Specifically, when a user uses the inner cup to process ingredients, the inner and outer cups are nested together, with the lid covering the inner cup. The outer cup has a first lug, and the inner cup has a second lug that overlaps the first lug. A snap-on lid protrudes from the side of the main unit, engaging with the first and second lugs. The snap-on lid secures the first and second lugs, and the lid is also clamped between the main unit and the inner cup, ensuring the inner cup is reliably positioned within the outer cup. This design is easy to implement, featuring one-button intelligent operation. The user simply selects the corresponding function and then presses the "start" button; the machine will then perform the corresponding task without requiring the user to continuously press the main unit. However, with this inner and outer cup installation scheme, when only the outer cup is used, the latching lug on the main unit is too deep to properly engage with the lug on the outer cup, causing the outer cup to be unable to be effectively restrained. This results in the outer cup shaking violently and continuously emitting vibration noise when used alone.
[0004] Based on this, those skilled in the art would readily conceive of removing the lug on the inner cup and adapting the main unit's lid to the lug on the outer cup. While this achieves a limiting fit on the outer cup, the main unit's lid cannot effectively limit the inner cup, particularly in terms of circumferential rotation prevention. When a user processes food using the inner cup, the food inside can easily cause the inner cup to rotate circumferentially, preventing effective cutting and processing and severely impacting the user experience. Furthermore, to ensure the stability of the outer cup when used alone, the lid cannot be fitted with a third lug to engage with the lid. Thus, during operation, the food can cause the inner cup to rotate circumferentially, potentially leading to the lid rotating or shifting, resulting in food spillage. Utility Model Content
[0005] The purpose of this utility model is to provide a stable food processing machine to solve the problem that, under the premise that existing food processing machines can achieve multi-functional processing by setting inner and outer cups and that the outer cup can be used independently and has reliable positioning, the inner cup and cup lid are prone to rotation when the inner cup needs to be embedded in the outer cup during operation.
[0006] To achieve the above objectives, this utility model provides a stable food processing machine, including a cup body with a built-in stirring element and a main unit detachably connected to the cup body. The main unit is equipped with a motor that is drivenly connected to the stirring element. The cup body includes an outer cup and an inner cup detachably nested inside the outer cup. The outer cup has a lug, and the inner cup has a lid on top, which overlaps the lug of the outer cup. The main unit has a snap-fit cover that engages with the lug to hold the lid between the main unit and the lug. The maximum outer diameter of the inner cup is not greater than the inner diameter of the outer cup opening, so that the inner cup is nested inside the outer cup for operation. A first circumferential anti-rotation structure is provided between the top of the lid and the bottom of the main unit to restrict the rotation of the main unit relative to the lid. The lid has an extension that engages with the inner cup, and a second circumferential anti-rotation structure is provided between the extension and the inner sidewall of the inner cup to restrict the rotation of the inner cup relative to the lid, so that the inner cup is nested inside the outer cup for operation.
[0007] This application, by designing the cup body to include an outer cup and an inner cup detachably nested within the outer cup, allows users to select different suitable inner or outer cups to process the corresponding ingredients when using the food processor. This satisfies the processing needs of various ingredients, making the machine multi-functional and improving the user experience. The outer cup has a lug that secures itself to the main unit's lid, enabling one-button intelligent operation without the need for continuous pressing by the consumer. Simultaneously, the main unit, while securing the outer cup, also clamps the lid, initially limiting its position to prevent displacement of the inner cup and ensuring its proper functioning. Meanwhile, the maximum outer diameter of the inner cup is no greater than the inner diameter of the outer cup, allowing the inner cup to be nested inside the outer cup. This avoids the inner cup's outer diameter being too large relative to the outer cup's inner diameter, which would cause the main unit's lid to partially fit the inner cup, affecting the stability of the lid and outer cup when assembled separately. Furthermore, when the inner cup is embedded in the outer cup, the lid is circumferentially fixed by the first circumferential anti-rotation structure and is not easily rotated. The inner cup is further stabilized by the second circumferential anti-rotation structure, making the lid's operation more stable and effectively preventing the lid from shifting and causing food spillage.
[0008] In this design, by setting the inner cup to be completely nested within the outer cup, the bottom of the main unit can fit tightly against the top of the outer cup to ensure the stability of the entire machine. Specifically, the latches on the main unit effectively limit the movement of the outer cup's lugs and other limiting structures. When the user removes the inner cup from the outer cup to use the outer cup alone, the main unit and lid can stably close on top of the outer cup, and the bottom of the main unit can maintain a stable connection with the top of the outer cup, ensuring the stability of the outer cup when used alone. A first circumferential anti-rotation structure between the top of the lid and the bottom of the main unit further prevents the lid from rotating circumferentially, enhancing the stability of the connection. The lid also has an extension that inserts into the inner cup. A second circumferential anti-rotation structure between the extension and the inner wall of the inner cup further restricts the inner cup's rotation relative to the lid. This allows the extension to insert into the inner cup after the lid is closed, while the outer edge of the lid overlaps the lugs on the outer cup, achieving axial positioning of the lid. The lid and inner cup are circumferentially locked together by a second circumferential anti-rotation structure, preventing the inner cup from rotating relative to the lid. Therefore, the main unit, lid, and inner cup, through the first and second circumferential anti-rotation structures, achieve circumferential anti-rotation among themselves, ensuring stability during food processing and effectively preventing the inner cup from rotating when the mixing components rotate, thus guaranteeing the stability of food processing. Furthermore, when the inner cup is removed from the main unit for independent operation, the lid can still effectively lock together with the main unit and inner cup through the first and second circumferential anti-rotation structures, ensuring the stability of the inner cup during operation. This ensures smooth food processing whether the inner cup is operating alone or nested within the outer cup.
[0009] In a preferred embodiment of a stable food processing machine, the bottom of the main unit is provided with a downwardly extending ring rib, the top of the cup lid is provided with a ring groove that engages with the ring rib, and a first circumferential anti-rotation structure is provided between the ring groove and the ring rib.
[0010] By providing a downward-extending ring rib at the bottom of the main unit and a ring groove at the top of the cup lid that engages with the ring rib, and by placing a first circumferential anti-rotation structure between the ring groove and the ring rib, the cup lid and the main unit are radially positioned through the engagement of the ring groove and the ring rib, further enhancing the connection's strength. Furthermore, the ring rib and ring groove, while achieving radial positioning of the cup lid and the main unit, also form the first circumferential anti-rotation structure, serving a dual purpose and enhancing its functionality. This also eliminates the need for a separate first circumferential anti-rotation structure in other parts, simplifying the structural design and reducing production costs.
[0011] In a preferred embodiment of a stable food processing machine, the sidewall of the ring rib is provided with a first rib, and the sidewall of the ring groove is provided with a second rib that cooperates with the first rib in a circumferential anti-rotation manner along the sidewall of the ring rib. The first circumferential anti-rotation structure includes the first rib and the second rib.
[0012] By configuring the first circumferential anti-rotation structure to include a first rib and a second rib, which serve as reinforcing ribs for the sidewalls of the annular rib and the annular groove, and also as an anti-rotation structure to prevent the main unit from rotating circumferentially relative to the cup lid after it is properly fitted with the cup body, the first and second ribs can achieve circumferential contact and anti-rotation, ensuring the stability of the fit between the main unit and the cup lid. Furthermore, the first and second ribs can be formed simultaneously during the forming of the annular rib and the annular groove, simplifying the manufacturing process and helping to improve production efficiency and reduce production costs.
[0013] In a preferred embodiment of a stable food processing machine, one of the bottom end of the ring rib and the bottom wall of the ring groove is provided with a first anti-rotation groove, and the other of the two is provided with an anti-rotation rib inserted into the first anti-rotation groove to circumferentially abut against the first anti-rotation groove. The first circumferential anti-rotation structure includes the first anti-rotation groove and the first anti-rotation rib.
[0014] By setting the first circumferential anti-rotation structure to include a first anti-rotation groove and a first anti-rotation rib, after the main unit is installed in place, the first anti-rotation groove and the first anti-rotation rib are interlocked and engaged with each other, and the first anti-rotation rib can be grounded on the circumferential sidewall of the first anti-rotation groove to form a stable circumferential anti-rotation fit, ensuring the circumferential anti-rotation stability of the cup lid and the main unit.
[0015] In a preferred embodiment of a stable food processing machine, the sidewall of the annular rib is radially recessed to form a second anti-rotation groove, and the sidewall of the annular groove is provided with a third protruding rib inserted into the bottom opening of the second anti-rotation groove to engage with the second anti-rotation groove in a circumferential anti-rotation manner. The first circumferential anti-rotation structure includes the second anti-rotation groove and the third protruding rib.
[0016] By setting the first circumferential anti-rotation structure to include a second anti-rotation groove and a third rib, the second anti-rotation groove and the third rib, after being inserted and fitted, can not only achieve anti-rotation fit between the main unit and the cup lid in the circumferential direction, but also achieve precise positioning when the main unit is installed on the cup body, ensuring the accuracy of the fit between the cup body and the main unit, thereby improving the connection stability between the motor output end and the stirring component, and ensuring the stability of the whole machine operation.
[0017] In a preferred embodiment of a stable food processing machine, the bottom wall of the main unit is provided with an upper wavy surface extending circumferentially along the main unit, and the top wall of the cup lid is provided with a lower wavy surface adapted to the upper wavy surface. The concave and convex parts of the upper wavy surface and the lower wavy surface are aligned. The first circumferential anti-rotation structure includes the upper wavy surface and the lower wavy surface.
[0018] By setting the first circumferential anti-rotation structure to include an upper wave surface and a lower wave surface, the upper wave surface and the lower wave surface can achieve precise fitting and positioning when the main unit is installed. Furthermore, the upper wave surface and the lower wave surface have multiple concave and convex parts along the circumferential direction, thus enabling circumferential limiting in multiple directions. The concave and convex parts of the two are interlocked, enhancing the tightness of the connection between the cup lid and the main unit, thereby ensuring the stability and reliability of the processing machine when it is running at high speed.
[0019] In a preferred embodiment of a stable food processing machine, the bottom of the main unit is provided with a downwardly extending ring rib, the top of the cup lid is provided with a ring groove that engages with the ring rib, the top of the outer wall of the ring groove is provided with a top surface of an outwardly extending downward-curved edge, the lower wave surface is provided on the downward-curved edge, and the upper wave surface is provided on the outside of the ring rib.
[0020] By setting the lower wave surface on the lower flange and the upper wave surface on the outside of the ring rib, the circumferential length of the upper and lower wave surfaces is maximized, resulting in the most concave and convex parts on the upper and lower wave surfaces. This allows the upper and lower wave surfaces to achieve multiple circumferential limits after being fitted together, further improving the circumferential anti-rotation effect.
[0021] In a preferred embodiment of a stable food processing machine, the outer peripheral surface of the extension is provided with an outwardly extending second anti-rotation rib, and the inner sidewall of the inner cup is provided with an inwardly extending third anti-rotation rib. The second anti-rotation rib and the third anti-rotation rib are circumferentially abutting each other. The second circumferential anti-rotation structure includes the second anti-rotation rib and the third anti-rotation rib.
[0022] By including a second anti-rotation rib and a third anti-rotation rib in the second circumferential anti-rotation structure, after the cup lid is installed in place, the second anti-rotation rib and the third anti-rotation rib make circumferential contact, and the second anti-rotation rib stops the third anti-rotation rib in the circumferential direction. This achieves circumferential anti-rotation of the inner cup by the cup lid, ensuring the circumferential stability of the inner cup when food is processed inside, and ensuring the smooth processing of food.
[0023] In a preferred embodiment of a stable food processing machine, the inner cup is a metal inner cup, and the third anti-rotation rib is a turbulence rib formed by the inward stamping of the metal inner cup.
[0024] By setting the inner cup to a metal inner cup, the strength and lightness of the inner cup are improved, making it more convenient for users to use. Furthermore, the third anti-rotation rib is a flow-dispersing rib formed by the inward stamping of the metal inner cup. This flow-dispersing rib not only disperses the food and enhances the mixing effect, but also acts as a third anti-rotation rib to achieve circumferential anti-rotation with the second anti-rotation rib. This dual-purpose design eliminates the need for a separate third anti-rotation rib in the metal inner cup, simplifies the structure of the metal inner cup, and reduces production costs.
[0025] In a preferred embodiment of a stable food processing machine, the inner cup is provided with a flip-up handle; or,
[0026] The outer peripheral wall of the extension is provided with a fourth anti-rotation rib that protrudes radially outward, and the inner side wall of the inner cup is provided with a third anti-rotation groove that is inserted and matched with the fourth anti-rotation rib.
[0027] By providing a flip-up handle to the inner cup, users can flip the handle into the gap between the inner and outer cups when processing food. At the same time, when it is necessary to remove the inner cup from the outer cup, the handle can be used to remove and move the inner cup, making it convenient for users and improving the user experience.
[0028] By providing a fourth anti-rotation rib that protrudes radially outward on the outer peripheral wall of the extension, and providing a third anti-rotation groove on the inner side wall of the inner cup that engages with the fourth anti-rotation rib, the inner cup and the cup lid can achieve further anti-rotation and limiting through the cooperation of the fourth anti-rotation rib and the third anti-rotation groove, further ensuring the stability of the connection between the two. At the same time, the engagement of the fourth anti-rotation rib and the third anti-rotation groove can also achieve precise alignment between the cup lid and the inner cup, ensuring the accuracy of the connection between the two.

Detailed Implementation
[0044] To more clearly illustrate the overall concept of this utility model, a detailed description will be provided below with reference to the accompanying drawings.
[0045] 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.
[0046] like Figures 1 to 12 As shown, this utility model provides a stable food processing machine, including a cup body 3 with a built-in stirring element 5 and a main unit 1 detachably connected to the cup body 3. The main unit 1 is equipped with a motor 2 that is drivenly connected to the stirring element 5. The cup body 3 includes an outer cup 31 and an inner cup 32 detachably nested inside the outer cup 31. The maximum outer diameter of the inner cup 32 is not greater than the inner diameter of the outer cup 31. A cup lid 4 is provided on the top of the inner cup 32. The outer cup 31 is provided with a lug. The cup lid 4 is provided on the top of the inner cup 32 and overlaps the lug of the outer cup 31. The main unit 1 is provided with a snap-fit cover that cooperates with the lug to clamp the cup lid between the main unit and the lug. A first circumferential anti-rotation structure is provided between the top of the cup lid 4 and the bottom of the main unit 1 to restrict the rotation of the main unit 1 relative to the cup lid 4. The cup lid 4 is provided with an extension 42 that extends into the inner cup 32. A second circumferential anti-rotation structure is provided between the extension 42 and the inner side wall of the inner cup 32 to restrict the rotation of the inner cup 32 relative to the cup lid 4.
[0047] This application, by configuring the cup body 3 as including an outer cup 31 and a metal cup detachably nested within the outer cup 31, allows users to select different compatible inner cups 32 or outer cups 31 to process different ingredients when using the food processor. This satisfies the processing needs of various ingredients, making the machine multi-functional and improving the user experience. The outer cup 31 has a lug that fastens to the lid of the main unit 1, enabling one-button intelligent operation without the need for continuous pressing by the consumer. Simultaneously, while the main unit 1 is fastened to the outer cup 31, it also clamps the lid 4, initially limiting its position and preventing the lid's movement from causing the inner cup to shift and affecting its normal operation.
[0048] Meanwhile, the maximum outer diameter of the inner cup 32 is not greater than the inner diameter of the outer cup 31, allowing the inner cup 32 to be completely nested within the outer cup 31. This avoids the outer diameter being too large relative to the inner diameter of the outer cup 31, which would cause the lid 4 to partially fit the inner cup 32, affecting the stability of the assembly between the lid 4 and the outer cup 31. The inner cup 32 described in this embodiment may or may not have a lug; the accompanying drawings show it as having a lug. In other words, compared to the prior art, the inner cup of this application does not have a lug that overlaps with the lug of the outer cup.
[0049] Meanwhile, by setting the inner cup 32 to be completely nested inside the outer cup 31, the bottom of the main unit 1 can be tightly fitted with the top of the outer cup 31 to ensure the stability of the whole machine. That is, the buckle cover on the main unit 1 can effectively limit the limiting structure such as the lug on the outer cup 31. When the user takes the inner cup 32 out of the outer cup 31 and uses the outer cup 31 alone, the cup cover 4 can also be stably closed on the outer cup 31, and the bottom of the main unit 1 can be stably connected with the top of the outer cup 31 to ensure the stability of the outer cup 31 when used alone. Furthermore, the cup lid 4 has an extension 42 that extends into the inner cup 32. A first circumferential anti-rotation structure is provided between the top of the cup lid 4 and the bottom of the main unit 1, allowing the extension 42 to penetrate deep into the inner cup 32 after the cup lid 4 is closed. Simultaneously, the outer edge of the cup lid 4 can overlap the outer cup 31, achieving axial positioning of the cup lid 4. The first circumferential anti-rotation structure also enables the cup lid 4 and the main unit 1 to achieve circumferential limiting cooperation, preventing the cup lid 4 from rotating circumferentially relative to the main unit 1 and improving the stability of their connection. The cup lid 4 also has an extension 42 that extends into the inner cup. The extension 42 within the inner cup 32 has a second circumferential anti-rotation structure between it and the inner wall of the inner cup 32. This structure limits the circumferential movement of the lid 4 and the inner cup 32, preventing the inner cup 32 from rotating relative to the lid 4. Therefore, the main unit 1, lid 4, and inner cup 32 achieve circumferential anti-rotation through the first and second circumferential anti-rotation structures, ensuring stability during food processing and effectively preventing the inner cup 32 from rotating when the stirring component 5 rotates, thus guaranteeing the stability of food processing. Furthermore, when the inner cup 32 is removed from the main unit 1 for independent operation, the lid 4 can still effectively limit its movement through the first and second circumferential anti-rotation structures, ensuring the stability of the inner cup 32 during operation. This ensures smooth food processing whether the inner cup 32 is operating alone or nested within the outer cup 31.
[0050] It should be noted that this application does not specifically limit the forming position of the first circumferential anti-rotation structure, which can be any of the following embodiments:
[0051] Example 1: As Figure 4 , Figure 5 , Figure 6 , Figure 7 , Figure 8 , Figure 9 As shown, in this embodiment, the bottom of the host 1 is provided with a downwardly extending ring rib 11, the top of the cup lid 4 is provided with a ring groove 41 that is inserted and matched with the ring rib 11, and the first circumferential anti-rotation structure is provided between the ring groove 41 and the ring rib 11.
[0052] By providing a downward-extending annular rib 11 at the bottom of the main unit 1, and an annular groove 41 at the top of the cup lid 4 that engages with the annular rib 11, and by placing a first circumferential anti-rotation structure between the annular groove 41 and the annular rib 11, the cup lid 4 and the main unit 1 are radially positioned through the engagement of the annular groove 41 and the annular rib 11, further enhancing the connection's robustness. Furthermore, the annular rib 11 and the annular groove 41, while achieving radial positioning of the cup lid 4 and the main unit 1, also form the first circumferential anti-rotation structure, serving a dual purpose and enhancing its functionality. This also eliminates the need for a separate first circumferential anti-rotation structure in other locations, simplifying the structural design and reducing production costs.
[0053] It should be further noted that this application does not specifically limit the first circumferential anti-rotation structure in this embodiment, and it can be any of the following embodiments:
[0054] Implementation method 1: such as Figure 4 , Figure 5 As shown, in this embodiment, the side wall of the ring rib 11 is provided with a first protruding rib 111, and the side wall of the ring groove 41 is provided with a second protruding rib 411 that cooperates with the first protruding rib 111 in a circumferential anti-rotation manner along the side wall of the ring rib. The first protruding rib 111 abuts against the second protruding rib 411 on the outer circumferential side. The first circumferential anti-rotation structure includes the first protruding rib 111 and the second protruding rib 411.
[0055] By configuring the first circumferential anti-rotation structure to include a first rib 111 and a second rib 411, the first rib 111 and the second rib 411 serve as reinforcing ribs for the sidewalls of the annular rib and the annular groove, respectively. They also act as anti-rotation structures to prevent the main unit from rotating circumferentially relative to the cup lid after it is properly fitted with the cup body. In other words, the first rib 111 and the second rib 411 can achieve circumferential contact and anti-rotation, ensuring the stability of the fit between the main unit and the cup lid. Furthermore, during the forming process of the annular rib and the annular groove, the first rib 111 and the second rib 411 can be formed simultaneously, simplifying the manufacturing process and helping to improve production efficiency and reduce production costs.
[0056] Specifically, when the user places the main unit 1 on top of the cup lid 4, if the first rib 111 is in circumferential contact with the second rib 411, the two can achieve circumferential anti-rotation; if the first rib 111 and the second rib 411 are not in contact, when the stirring component 5 rotates, the inner cup 32 can drive the cup lid 4 to rotate by means of the limiting effect of the second circumferential anti-rotation structure. Then, when the cup lid 4 rotates to the point where the first rib 111 and the second rib 411 are in contact, the main unit 1, the inner cup 32 and the cup lid 4 are circumferentially anti-rotated.
[0057] Implementation method 2: such as Figure 8 , Figure 9As shown, in this embodiment, one of the bottom wall of the ring rib 11 and the bottom wall of the ring groove 41 is provided with a first anti-rotation groove 112, and the other of them is provided with an anti-rotation rib that is inserted into the first anti-rotation groove to circumferentially abut against the first anti-rotation groove 112. The first circumferential anti-rotation structure includes the first anti-rotation groove 112 and the first anti-rotation rib 412.
[0058] By setting the first circumferential anti-rotation structure to include a first anti-rotation groove 112 and a first anti-rotation rib 412, after the main unit 1 is installed in place, the first anti-rotation groove 112 and the first anti-rotation rib 412 are interlocked and engaged with each other, and the first anti-rotation rib 412 can be grounded on the circumferential side wall of the first anti-rotation groove 112 to form a stable anti-rotation engagement, ensuring the circumferential anti-rotation stability of the cup lid 4 and the main unit 1.
[0059] Specifically, such as Figure 8 , Figure 9 As shown, the first anti-rotation groove 112 is provided at the bottom end of the annular rib 11, and the first anti-rotation rib 412 is provided on the bottom wall of the annular groove 41. At the same time, the circumferential length of the first anti-rotation groove 112 is greater than the circumferential length of the first anti-rotation rib 412. Therefore, when the user installs the main unit 1 on the cup body 3, the first anti-rotation groove 112 and the first anti-rotation rib 412 do not need to be precisely aligned to achieve the assembly of the two. And when the cup lid 4 rotates with the cup body 3, the anti-rotation engagement of the first anti-rotation groove 112 and the first anti-rotation rib 412 is achieved.
[0060] Implementation Method 3: In this implementation method, one of the sidewalls of the annular rib 11 and the annular groove 41 is provided with a radially protruding third rib, and the other of the two is provided with a second anti-rotation groove that is inserted and engaged with the third rib. The first circumferential anti-rotation structure includes the second anti-rotation groove and the third rib. More preferably, the third rib is provided on the sidewall of the annular groove 41, and the second anti-rotation groove is provided on the sidewall of the annular rib 11 facing the third rib. Of course, the second anti-rotation groove and the third rib can be provided on the two sidewalls of the annular rib 11 and the annular groove 41, which will not be described in detail here.
[0061] Specifically, in a preferred embodiment, the sidewall of the annular rib is radially recessed to form a second anti-rotation groove. The sidewall of the annular groove is provided with a third rib that is inserted into the bottom opening of the second anti-rotation groove to engage with the second anti-rotation groove in a circumferential anti-rotation manner. The third rib can be formed by the sidewall of the annular groove being recessed toward the second anti-rotation groove, or by a protrusion on the surface of the sidewall of the annular groove.
[0062] By setting the first circumferential anti-rotation structure to include a second anti-rotation groove and a third rib, the second anti-rotation groove and the third rib, after being inserted and fitted, can not only achieve anti-rotation fit between the main unit 1 and the cup lid 4 in the circumferential direction, but also achieve precise positioning when the main unit 1 is installed on the cup body 3 with the help of the second anti-rotation groove and the third rib, ensuring the accuracy of the fit between the cup body 3 and the main unit 1, thereby improving the connection stability between the output end of the motor 2 and the stirring component 5, and ensuring the stability of the whole machine operation.
[0063] Example 2: Figure 10 , Figure 11 , Figure 12 As shown, in this embodiment, the bottom wall of the main unit 1 is provided with an upper wave surface 12 extending circumferentially along the main unit 1, and the top wall of the cup lid 4 is provided with a lower wave surface 43 adapted to the upper wave surface 12. The upper wave surface 12 and the lower wave surface 43 are aligned with each other. The first circumferential anti-rotation structure includes the upper wave surface 12 and the lower wave surface 43.
[0064] By setting the first circumferential anti-rotation structure to include an upper wave surface 12 and a lower wave surface 43, the upper wave surface 12 and the lower wave surface 43 can achieve precise fitting and positioning when the main unit 1 is installed in place. Furthermore, the upper wave surface 12 and the lower wave surface 43 have multiple concave and convex positions along the circumferential direction, thus enabling circumferential limiting in multiple directions. The concave and convex positions of the two are interlocked, enhancing the tightness of the connection between the cup lid 4 and the main unit 1, thereby ensuring the stability and reliability of the processing machine when it is running at high speed.
[0065] It should be noted that this application does not limit the specific positions of the upper wave surface 12 and the lower wave surface 43. As one preferred embodiment of this application, such as... Figure 10 , Figure 11 As shown, the bottom of the main unit 1 is provided with a downwardly extending ring rib 11, the top of the cup lid 4 is provided with a ring groove 41 that is inserted and matched with the ring rib 11, the top of the outer wall of the ring groove 41 is provided with a top surface of an outwardly extending downward flange, the lower wave surface 43 is provided on the downward flange, and the upper wave surface 12 is provided on the outside of the ring rib 11.
[0066] By setting the lower wave surface 43 on the lower flange and the upper wave surface 12 on the outside of the ring rib 11, the circumferential length of the upper wave surface 12 and the lower wave surface 43 is maximized, resulting in the maximum number of concave and convex parts of the upper wave surface 12 and the lower wave surface 43. This allows the upper wave surface 12 and the lower wave surface 43 to achieve circumferential restraint in more directions after they are combined, further improving the circumferential anti-rotation effect.
[0067] Understandably, when the bottom of the main unit is provided with ring ribs, the upper wave surface can be set on the bottom surface of the ring ribs, while the lower wave surface can be set on the bottom wall of the ring groove.
[0068] It should be noted that this application does not specifically limit the second circumferential anti-rotation structure. As one preferred embodiment of this application, such as... Figure 6 , Figure 7 As shown, the outer circumferential surface of the extension 42 is provided with an outwardly extending second anti-rotation rib 421, and the inner sidewall of the inner cup 32 is provided with an inwardly extending third anti-rotation rib 321. The second anti-rotation rib and the third anti-rotation rib are circumferentially abutted, that is, the second anti-rotation rib 421 abuts against the outer circumferential side of the third anti-rotation rib 321. The second circumferential anti-rotation structure includes the second anti-rotation rib 421 and the third anti-rotation rib 321.
[0069] By including a second anti-rotation rib 421 and a third anti-rotation rib 321 in the second circumferential anti-rotation structure, after the cup lid 4 is installed in place, the second anti-rotation rib 421 and the third anti-rotation rib 321 make circumferential contact, and the second anti-rotation rib 421 stops the third anti-rotation rib 321 in the circumferential direction. This achieves circumferential anti-rotation of the inner cup 32 by the cup lid 4, ensuring the circumferential stability of the inner cup 32 when food is processed in the inner cup 32, and ensuring the smooth processing of food.
[0070] It should be further noted that this application does not specifically limit the structure of the third anti-rotation rib 321. It can be a separate, inwardly extending third anti-rotation rib 321 provided on the inner sidewall of the inner cup 32. Alternatively, as a preferred embodiment of this application, such as... Figure 6 , Figure 7 As shown, the inner cup 32 is a metal inner cup 32, and the third anti-rotation rib 321 is a turbulence rib formed by the inward stamping of the metal inner cup 32. Of course, the inner cup 32 is not limited to a metal inner cup 32; it can also be a glass inner cup 32.
[0071] By setting the inner cup 32 as a metal inner cup 32, the strength and lightness of the inner cup 32 are improved, making it more convenient for users to use. Furthermore, the third anti-rotation rib 321 is a flow-dispersing rib formed by the inward stamping of the metal inner cup 32. This allows the flow-dispersing rib to not only turbulent the food and enhance the mixing effect, but also to act as the third anti-rotation rib 321 to achieve circumferential anti-rotation with the second anti-rotation rib 421. This dual-purpose design eliminates the need for a separate third anti-rotation rib 321 in the metal inner cup 32, simplifies the structure of the metal inner cup 32, and reduces production costs.
[0072] In a preferred embodiment of this application, the inner cup 32 is provided with a flip-up handle.
[0073] By providing a flip-up handle to the inner cup 32, users can flip the handle to fit between the inner cup 32 and the outer cup 31 when processing food. Additionally, when it is necessary to remove the inner cup 32 from the outer cup 31, the handle can be used to remove and move the inner cup 32, making it convenient for users and improving the user experience.
[0074] In a preferred embodiment of this application, the outer peripheral wall of the extension 42 is provided with a fourth anti-rotation rib that protrudes radially outward, and the inner side wall of the inner cup 32 is provided with a third anti-rotation groove that is inserted and engaged with the fourth anti-rotation rib.
[0075] By providing a fourth anti-rotation rib that protrudes radially outward on the outer peripheral wall of the extension 42, and providing a third anti-rotation groove on the inner side wall of the inner cup 32 that engages with the fourth anti-rotation rib, the inner cup 32 and the cup lid 4 can achieve further anti-rotation and limiting through the cooperation of the fourth anti-rotation rib and the third anti-rotation groove, thereby further ensuring the stability of the connection between the two. At the same time, the cup lid 4 and the inner cup 32 can be precisely aligned by means of the engagement of the fourth anti-rotation rib and the third anti-rotation groove, ensuring the accuracy of the connection between the two.
