Description

A structurally stable food processing machine Technical Field

[0001] This utility model relates to the field of household appliance technology, specifically to a food processing machine with a stable structure. 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, the applicant's earlier patent application CN220124549U disclosed a food processor that comprises a first cup and a second cup. The first cup is housed within the second cup and processes ingredients. Different cups are used to process different ingredients, meeting diverse user needs. To ensure the stability of the first and second cups' connection, an upward-protruding groove is provided at the bottom of the first cup, with its lower opening allowing the insertion of a positioning post from the second cup, thus enhancing the stability of the connection. However, in this design, the inner cup is intended for processing smaller quantities of complementary foods; therefore, it is designed to connect to the back of the cavity where the main unit's lid is mounted. In this design, the second cup, located on the outer side, operates independently, while the first cup, located within the second cup, is installed within the second cup to function.

[0004] However, when increasing the capacity of the inner cup, those skilled in the art would readily consider increasing its outer diameter, making it as close as possible to the outer cup. To facilitate handling the inner cup, lugs are typically provided. When the user uses the inner cup to process food, the inner and outer cups are stacked together, with the lid covering the inner cup and engaging with the lugs on both. However, when using only the outer cup, if the lugs on the lid are too deep, they cannot properly engage with the lugs on the outer cup, resulting in the outer cup not being effectively contained. Therefore, the thickness of the inner cup lugs is limited; they cannot be too thick, otherwise the lid's engagement lugs will not be able to close tightly when the outer cup is used alone. Furthermore, after investigating consumer needs, for double-cup meat grinders, users expect both a transparent glass cup and a high-quality steel cup to process different foods and to easily distinguish between them. If the outer cup is replaced with a metal cup and the inner cup with a glass cup, users will find it difficult to immediately recognize the double-cup structure when purchasing. Therefore, most existing double-cup structures use a glass outer cup and a metal inner cup. Furthermore, during our research, we discovered that users have varying requirements for different functions of the machine. For example, when grinding meat, users need to see the working process inside the cups to achieve the desired meat texture, but when kneading dough, they only need it to form a ball. Therefore, the meat grinding process requires visualization, hence the choice of a glass outer cup and a metal inner cup for kneading dough. However, the metal inner cup is relatively thin. In actual use, users have found that when processing heavy ingredients through the metal inner cup, such as kneading dough, the mixing component experiences a large torque. This torque is transmitted to the positioning post of the metal inner cup, causing it to swing around with the connection point between the positioning post and the metal inner cup as a fulcrum. Because the metal inner cup is thin, the stress concentration at the connection point with the positioning post can cause deformation or even damage to the bottom wall near the positioning post. This leads to the positioning post tilting. When the mixing component engages with the positioning post, it tilts to one side, causing one end of the mixing component to stick up and be far from the bottom wall of the metal inner cup. Consequently, the food in that part cannot be mixed by the mixing component, resulting in insufficient processing of the food and seriously affecting the user experience. Summary of the Invention

[0005] The purpose of this utility model is to provide a food processing machine with a stable structure. Based on the premise that the inner cup needs to be installed inside the outer cup to work, it further solves the technical problem that the bottom wall near the positioning column of the inner cup is easily deformed when the inner cup is used for kneading dough due to the large load.

[0006] To achieve the above objectives, this utility model provides a structurally 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 drively connected to the stirring element. The cup body includes an outer cup and a metal inner cup that is detachably nested inside the outer cup for operation. The metal inner cup can be used for kneading dough.

[0007] The mounting port is located on the bottom wall of the metal inner cup, running vertically through it.

[0008] A first positioning post is provided at the mounting port. The first positioning post extends upward from the mounting port and is inserted into the bottom of the stirring component. The first positioning post is provided with a first positioning groove with the opening facing downward.

[0009] The second positioning post is located on the bottom wall of the outer cup. The second positioning post includes a second insertion post that extends upward and is inserted into the first positioning groove.

[0010] A reinforcing member is provided below the mounting port, and the reinforcing member cooperates with the first positioning post to clamp the bottom wall of the metal inner cup from above and below.

[0011] This application, by configuring the cup body to include an outer cup and a detachably nested metal inner cup within the outer cup, allows users to select different suitable metal inner or outer cups 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. Simultaneously, the first positioning post extends upward from the mounting port and inserts into the bottom of the mixing component, ensuring a stable connection between the mixing component and the metal inner cup, guaranteeing stability during rotation. Furthermore, the second positioning post extends upward and inserts into the first positioning groove, ensuring a stable connection between the outer cup and the metal inner cup through the insertion of the second post into the first positioning groove. This also prevents relative displacement of the metal inner cup when it is installed inside the outer cup, further enhancing the overall structural stability. In this design, the outer diameter of the first positioning post is larger than that of the second positioning post, thus making the first positioning post more stable. When the inner metal cup is nested inside the outer cup for kneading, the first positioning post can effectively support and position the kneading rod, ensuring the stability of the kneading rod's position and thus ensuring the smooth kneading process.

[0012] Furthermore, the reinforcing member is located below the mounting port. The reinforcing member and the first positioning post clamp the bottom wall of the metal inner cup from above and below, thereby reinforcing the bottom wall of the metal inner cup at the mounting port. This greatly improves the strength of the bottom wall of the metal inner cup at the mounting port, thus preventing the deformation or even damage of the bottom wall of the metal inner cup caused by excessive load on the mixing component when processing ingredients requiring high torque, such as when kneading dough. This prevents the first positioning post from bearing too much load and causing it to swing with the bottom wall of the metal inner cup at the mounting port as a fulcrum. Consequently, the mixing component may tilt during food processing, preventing ingredients with larger gaps from participating in the processing. This ensures the stability of the bottom wall structure of the metal inner cup, thereby ensuring the stability of food processing and extending the service life of the entire machine.

[0013] In a preferred embodiment of a structurally stable food processing machine, the reinforcing member is a first reinforcing plate disposed on the bottom surface of the bottom wall of the metal inner cup. The first reinforcing plate has an upwardly raised portion in the middle that is adapted to the first positioning groove. The raised portion has a second positioning groove with its opening facing downward. The second insertion post is inserted into the second positioning groove.

[0014] By setting the reinforcing member as a first reinforcing plate located on the bottom surface of the bottom wall of the inner metal cup, and having an upwardly raised portion in the middle of the first reinforcing plate that matches the first positioning groove, the first reinforcing plate not only supports and reinforces the bottom surface of the inner metal cup, but also, through the precise fit between the raised portion and the first positioning groove, provides radial support for the first positioning post. This allows the first positioning post to transfer force to the raised portion when subjected to a large radial force, and then to the first reinforcing plate, thus dispersing the torque and preventing localized stress concentration caused by excessive force on the first positioning post and direct torque transfer to the bottom wall of the inner metal cup. This further prevents deformation or damage to the bottom wall of the inner metal cup. Simultaneously, the raised portion has a downward-facing second positioning groove, with the second positioning post interlocking with it. This allows the raised portion to support the first positioning post while also interlocking with the second positioning post, ensuring the stability of the connection between the inner and outer metal cups and preventing displacement of the overall structure during use, further improving the stability and durability of the food processing machine.

[0015] In a preferred embodiment of a structurally stable food processing machine, the cup body further includes a connector that passes through the top wall of the second positioning groove from bottom to top and is fastened to the top wall of the first positioning groove.

[0016] By including a connector in the cup body, and having the connector pass through the top wall of the second positioning groove from bottom to top and be fastened to the top wall of the first positioning groove, the first reinforcing plate can be tightly connected to the first positioning post through the connector, so that the raised part and the first positioning post are fixed as a whole. This allows the first positioning post to directly transmit the torque to the raised part when subjected to a large force, thereby dispersing the torque and further preventing the bottom wall of the metal inner cup from deforming due to a large force.

[0017] In a preferred embodiment of a structurally stable food processing machine, the top end of the second insertion post is clearance-fitted with the bottom end of the connector.

[0018] By setting the top of the second insertion post and the bottom of the connector to a clearance fit, the collision interference between the second insertion post and the bottom of the connector is effectively avoided after the outer cup and the metal inner cup are connected. This would prevent the second insertion post from being fully inserted into the second positioning groove, thus causing the metal inner cup and the outer cup to not be tightly connected.

[0019] In a preferred embodiment of a structurally stable food processing machine, the outer wall of the raised portion is provided with an external thread, and the inner wall of the first positioning groove is provided with an internal thread that mates with the external thread.

[0020] By providing external threads on the outer side wall of the raised portion and internal threads on the inner side wall of the first positioning groove that mate with the external threads, the raised portion can achieve a fixed connection between the first reinforcing plate and the first positioning post through the threaded connection of the external and internal threads when it mates with the first positioning groove. This makes the connection more convenient and quick, eliminates the need for additional connecting parts to connect the two, simplifies the assembly process, improves production efficiency, and ensures the firmness and stability of the connection.

[0021] In a preferred embodiment of a structurally stable food processing machine, the bottom of the first positioning column is provided with a second reinforcing plate extending radially outward, and the second reinforcing plate is disposed on the top surface of the bottom wall of the metal inner cup.

[0022] By setting a second reinforcing plate on the top surface of the bottom wall of the metal inner cup, and extending radially outward from the bottom wall of the first positioning post, the second reinforcing plate, together with the first reinforcing plate, achieves the upper and lower clamping of the bottom wall of the metal inner cup at the installation port. This allows the torque to be distributed to the first and second reinforcing plates when the first positioning post is subjected to a large force, greatly enhancing the deformation resistance of the bottom wall of the metal inner cup, ensuring the stability of the metal inner cup structure, and thus ensuring the smooth processing of food ingredients.

[0023] In a preferred embodiment of a structurally stable food processing machine, the second reinforcing plate is integrally formed on the bottom outer side of the first positioning column.

[0024] By integrally molding the second reinforcing plate and the first positioning post, when the first positioning post is subjected to a large force, it can be directly transferred to the second reinforcing plate. The large contact area between the second reinforcing plate and the bottom wall of the metal inner cup effectively disperses the torque, reduces local stress concentration on the bottom wall of the metal inner cup, and further ensures the stability of the bottom wall structure. Simultaneously, when the bottom wall of the metal inner cup deforms upwards, the second reinforcing plate strengthens the bottom wall and transfers the force to the first positioning post during upward deformation, ensuring the strength of the second reinforcing plate and providing support against deformation.

[0025] In a preferred embodiment of a structurally stable food processing machine, a first sealing element is clamped between the reinforcing member and the bottom surface of the bottom wall of the metal inner cup, and a second sealing element is clamped between the first positioning post and the top surface of the bottom wall of the metal inner cup.

[0026] By clamping a first sealing element between the reinforcing member and the bottom surface of the metal inner cup, and clamping a second sealing element between the first positioning post and the top surface of the metal inner cup's bottom wall, this double-sealing design effectively prevents liquids or powders from leaking out through the gap between the reinforcing plate and the bottom wall of the metal inner cup during food processing, ensuring hygiene and safety during food processing. Furthermore, since users typically do not disassemble the first positioning post and the reinforcing member, the double sealing in this application effectively prevents food from seeping into the gap between the first positioning post or the reinforcing member and the bottom wall of the metal inner cup, thus avoiding the problem of trapped food being difficult to clean and producing odors.

[0027] In a preferred embodiment of a structurally stable food processing machine, the first seal and the second seal are connected by a connecting section, and the connecting section is sealed at the mounting port.

[0028] By connecting the first and second seals via a connecting section, which is then sealed at the mounting port, the overall sealing performance is further enhanced. This ensures that food remains stably within the metal inner cup during processing, preventing leakage. Simultaneously, it further guarantees the sealing performance between the first positioning post and the mounting port, preventing food from seeping between them, which could lead to difficult cleaning and unpleasant odors.

[0029] In a preferred embodiment of a structurally stable food processing machine, the sidewall of the second insertion post is clearance-fitted with the inner sidewall of the first positioning groove.

[0030] By setting the side wall of the second insertion post and the inner side wall of the first positioning groove to a clearance fit, the second insertion post can be installed and disassembled smoothly without excessive shaking when it is engaged with the first positioning groove, thus ensuring the stability of the insertion. At the same time, the clearance fit design can also effectively reduce friction and wear and noise, extend the service life of components, and further improve the overall durability and reliability of the food processing machine.

Detailed Implementation

[0040] To more clearly illustrate the overall concept of this utility model, a detailed description will be provided below with reference to the accompanying drawings.

[0041] 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.

[0042] As shown in Figures 1 to 6, this utility model provides a structurally stable food processing machine, including a cup body with a built-in stirring element and a main unit 1 detachably connected to the cup body. The main unit 1 is equipped with a motor 2 that is driven and connected to the stirring element. The cup body includes an outer cup 3 and a metal inner cup 4 that is detachably nested inside the outer cup 3 for operation. The metal inner cup 4 can be used for kneading dough.

[0043] The mounting port is located on the bottom wall of the metal inner cup 4, extending from top to bottom.

[0044] The first positioning post 5 is located at the mounting port. The first positioning post 5 extends upward from the mounting port and is inserted into the bottom of the stirring component. The first positioning post 5 is provided with a first positioning groove 51 with the opening facing downward.

[0045] The second positioning post is located on the bottom wall of the outer cup 3. The second positioning post includes a second insertion post 8 that extends upward and is inserted into the first positioning groove 51.

[0046] A reinforcing member is provided below the mounting port. The reinforcing member cooperates with the first positioning post 5 to clamp the bottom wall of the metal inner cup 4 from the top and bottom and to block the mounting port.

[0047] This application, by configuring the cup body to include an outer cup 3 and a detachably nested metal inner cup 4 within the outer cup 3, allows users to select different compatible metal inner cups 4 or outer cups 3 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. Simultaneously, the first positioning post extends upward from the mounting port and inserts into the bottom of the mixing component, ensuring a stable connection between the mixing component and the metal inner cup 4, guaranteeing the stability of the mixing component during rotation. Furthermore, the second positioning post includes a second insertion post 8 extending upward and inserting into the first positioning groove 51. This ensures a stable connection between the outer cup 3 and the metal inner cup 4 through the insertion of the second insertion post 8 into the first positioning groove 51, preventing relative displacement of the metal inner cup 4 when it is nested within the outer cup 3, further enhancing the overall structural stability. Meanwhile, the outer diameter of the first positioning post 5 is larger than that of the second positioning post, thus making the first positioning post more stable. When the dough is kneaded by the inner metal cup 4 nested inside the outer cup 3, the first positioning post can effectively support and position the kneading rod, ensuring the stability of the kneading rod position, and thus ensuring the smooth progress of kneading.

[0048] Furthermore, a reinforcing member is located below the mounting opening. This reinforcing member cooperates with the first positioning post 5 to clamp the bottom wall of the inner metal cup 4 from both above and below, thus reinforcing the bottom wall of the inner metal cup 4 at the mounting opening. This significantly improves the strength of the bottom wall of the inner metal cup 4 at the mounting opening, preventing deformation or even damage to the bottom wall of the inner metal cup 4 caused by excessive load on the stirring component during high-torque processing, such as when kneading dough. This prevents the first positioning post 5 from bearing an excessive load after being transferred to it, causing it to swing with the bottom wall of the inner metal cup 4 at the mounting opening as a fulcrum. Consequently, this could lead to the stirring component tilting during food processing, preventing food from being processed due to larger gaps. This ensures the stability of the bottom wall structure of the inner metal cup 4, thereby ensuring the stability of food processing and extending the service life of the entire machine. In a preferred embodiment, the inner metal cup 4 is a steel cup, which greatly improves its strength and can be used for kneading dough. The outer cup 3 is a glass cup used for mincing meat, allowing the user to observe the minced meat status inside the outer cup 3 in real time.

[0049] Furthermore, the reinforcing member is located at the edge of the mounting opening. Specifically, the inner diameter of the reinforcing member can be slightly smaller than the inner diameter of the mounting opening, or it can be the same as the inner diameter of the mounting opening, or it can be larger than the inner diameter of the mounting opening. Preferably, the relationship between the inner diameter r1 of the mounting opening and the inner diameter r2 of the reinforcing member is: 0.9r1≤r2≤1.3r1.

[0050] It should be noted that this application does not specifically limit the structure of the reinforcing member. As a preferred embodiment of this application, as shown in FIG2, the reinforcing member is a first reinforcing plate 7 provided on the bottom surface of the bottom wall of the metal inner cup 4. The first reinforcing plate 7 has an upwardly raised part 71 in the middle that is adapted to the first positioning groove 51. The raised part 71 has a second positioning groove 711 with the opening facing downward. The second insertion post 8 is inserted into the second positioning groove 711.

[0051] By setting the reinforcing member as a first reinforcing plate 7 on the bottom surface of the bottom wall of the metal inner cup 4, and the first reinforcing plate 7 having an upwardly raised portion 71 in the middle that is adapted to the first positioning groove 51, the first reinforcing plate 7 can not only support and reinforce the bottom surface of the bottom wall of the metal inner cup 4, but also achieve radial support of the first positioning post 5 through the precise cooperation between the raised portion 71 and the first positioning groove 51. This allows the first positioning post 5 to transfer the force to the raised portion 71 when subjected to a large radial force, and then to the first reinforcing plate 7 through the raised portion 71, thereby dispersing the torque and avoiding local stress concentration caused by the first positioning post 5 being subjected to excessive force and directly transferring the torque to the bottom wall of the metal inner cup 4, further preventing deformation or damage to the bottom wall of the metal inner cup 4. Meanwhile, the raised portion 71 is provided with a second positioning groove 711 with the opening facing downward. The second positioning post is inserted into the second positioning groove 711. While the raised portion 71 supports the first positioning post 5, it can also be inserted into the second insertion post 8 to ensure the stability of the connection between the inner metal cup 4 and the outer cup 3. This ensures that the inner metal cup does not shift when it is nested inside the outer cup, further improving the stability and durability of the food processing machine.

[0052] It should be further noted that this application does not specifically limit the connection method between the raised portion 71 and the first positioning groove 51, which can be any of the following embodiments:

[0053] Example 1: As shown in Figure 2, in this example, the cup body also includes a connector 9. The connector 9 passes through the top wall of the second positioning groove 711 from bottom to top and is fastened to the top wall of the first positioning groove 51. Preferably, the connector 9 is a screw. The top wall of the first positioning groove 51 is provided with a clearance hole for the screw to pass through, and the top wall of the first positioning groove 51 is provided with a screw hole that is threaded to engage with the screw.

[0054] By including the connector 9 in the cup body, and having the connector 9 pass through the top wall of the second positioning groove 711 from bottom to top and be fastened to the top wall of the first positioning groove 51, the first reinforcing plate 7 can be tightly connected to the first positioning post 5 through the connector 9, so that the raised part 71 and the first positioning post 5 are fixed as a whole, so that when the first positioning post 5 is subjected to a large force, the torque can be directly transmitted to the raised part 71, thereby dispersing the torque and further avoiding the situation where the bottom wall of the metal inner cup 4 is subjected to a large force and deforms.

[0055] Furthermore, as shown in Figure 2, the top end of the second insertion post 8 is clearance-fitted with the bottom end of the connector 9.

[0056] By setting the top end of the second insertion post 8 and the bottom end of the connector 9 to a clearance fit, the collision interference between the second insertion post 8 and the bottom end of the connector 9 after the outer cup 3 and the metal inner cup 4 are connected is effectively avoided, which would prevent the second insertion post 8 from being fully inserted into the second positioning groove 711, and thus prevent the metal inner cup 4 and the outer cup 3 from being tightly connected.

[0057] Example 2: In this example, the outer side wall of the raised portion 71 is provided with an external thread, and the inner side wall of the first positioning groove 51 is provided with an internal thread that engages with the external thread.

[0058] By providing external threads on the outer side wall of the raised portion 71 and internal threads that mate with the external threads on the inner side wall of the first positioning groove 51, the raised portion 71 can achieve a fixed connection between the first reinforcing plate 7 and the first positioning post 5 through the threaded connection of the external and internal threads when it mates with the first positioning groove 51. This makes the connection more convenient and quick, eliminating the need for a separate connecting piece 9 to connect the two, simplifying the assembly process, improving production efficiency, and ensuring the firmness and stability of the connection.

[0059] Example 3: In this example, the first reinforcing plate 7 is bonded and fixed to the outer bottom wall of the metal inner cup 4, eliminating the need for other connecting structures, simplifying the structure of the first reinforcing plate 7, and helping to improve its production efficiency and reduce production costs. Whether the first reinforcing plate has a raised portion is not limited here.

[0060] As a preferred embodiment of this application, as shown in FIG2, the bottom of the first positioning post 5 is provided with a second reinforcing plate 6 extending radially outward. The second reinforcing plate 6 is provided on the top surface of the bottom wall of the metal inner cup 4. Preferably, the inner diameter of the second reinforcing plate 6 is the same as the inner diameter of the mounting opening. Of course, the inner diameter of the second reinforcing plate 6 can be slightly larger or slightly smaller than the inner diameter of the mounting opening.

[0061] By providing a second reinforcing plate 6 extending radially outward at the bottom of the first positioning post 5, and the second reinforcing plate 6 being located on the top surface of the bottom wall of the metal inner cup 4, in conjunction with the first reinforcing plate 7, the bottom wall of the metal inner cup 4 at the installation port is clamped from top to bottom. This allows the torque to be distributed to the first reinforcing plate 7 and the second reinforcing plate 6 when the first positioning post 5 is subjected to a large force, greatly enhancing the deformation resistance of the bottom wall of the metal inner cup 4, ensuring the stability of the metal inner cup 4 structure, and thus ensuring the smooth processing of food ingredients.

[0062] It should be noted that this application does not specifically limit the relative relationship between the second reinforcing plate 6 and the first positioning post 5. It can be formed separately and then connected to the first positioning post 5 by welding or bonding. Alternatively, as a preferred embodiment of this application, as shown in Figure 2, the second reinforcing plate 6 is integrally formed on the bottom outer side of the first positioning post 5.

[0063] By integrally molding the second reinforcing plate 6 and the first positioning post 5, when the first positioning post 5 is subjected to a large force, it can be directly transferred to the second reinforcing plate 6. The large contact area between the second reinforcing plate 6 and the bottom wall of the metal inner cup 4 effectively disperses the torque, reduces local stress concentration on the bottom wall of the metal inner cup 4, and further ensures the stability of the bottom wall structure of the metal inner cup 4. Simultaneously, when the bottom wall of the metal inner cup 4 deforms upwards, the second reinforcing plate 6 can reinforce the bottom wall of the metal inner cup 4 and transfer the force to the first positioning post 5 during upward deformation, ensuring the strength of the second reinforcing plate 6 and achieving the function of supporting and preventing deformation.

[0064] It is understandable that the lateral width of the side wall of the first positioning post can be widened to correspond to the upper and lower settings of the first reinforcing plate, preferably widened to the same size as the outer edge of the first reinforcing plate, so as to achieve a good upper and lower clamping effect on the bottom wall of the metal inner cup 2, and to make the strength and hardness of the first positioning post itself more reliable.

[0065] In a preferred embodiment of this application, a first sealing member is held between the reinforcing member and the bottom surface of the bottom wall of the metal inner cup, and a second sealing member is held between the first positioning post and the top surface of the bottom wall of the metal inner cup.

[0066] Specifically, as shown in Figures 5 and 6, the food processing machine includes a first reinforcing plate 7 and a second reinforcing plate 6 that clamp the bottom wall of the metal inner cup 4 from above and below. The second reinforcing plate 6 is located on the outer side of the bottom of the first positioning post. A first sealing element 10 is clamped between the first reinforcing plate 7 and the bottom wall of the metal inner cup 4, and a second sealing element 11 is clamped between the second reinforcing plate 6 and the bottom wall of the metal inner cup 4.

[0067] By clamping a first sealing element 10 between the first reinforcing plate 7 and the bottom wall of the metal inner cup 4, and clamping a second sealing element 11 between the second reinforcing plate 6 and the bottom wall of the metal inner cup 4, a double-sealing design effectively prevents liquids or powders from leaking out through the gaps between the reinforcing plates and the bottom wall of the metal inner cup 4 during food processing, ensuring hygiene and safety during food processing. Furthermore, users typically do not disassemble the first positioning post and the reinforcing plates, effectively preventing food from seeping into the space between the first positioning post or the reinforcing plate and the bottom wall of the metal inner cup 4, which could lead to difficult cleaning and unpleasant odors.

[0068] Furthermore, as shown in Figure 6, the first seal 10 and the second seal 11 are connected by a connecting section 12, and the connecting section 12 is sealed at the mounting port.

[0069] By connecting the first seal 10 and the second seal 11 through the connecting section 12, and sealing the connecting section 12 at the installation port, the sealing performance of the overall structure is further improved, ensuring that the food can remain stably inside the metal inner cup 4 during processing and avoiding the risk of leakage. At the same time, it further ensures the sealing performance between the first positioning post and the installation port, preventing food from seeping between them, which would make it difficult to clean and produce odors.

[0070] Understandably, the first sealing element 10 and the second sealing element 11 can also be two independent separate parts, respectively located between the first reinforcing plate 7 and the bottom wall of the metal inner cup 4, and between the second reinforcing plate 6 and the bottom wall of the metal inner cup 4.

[0071] As a preferred embodiment of this application, as shown in FIG2, the side wall of the second insertion post 8 is clearance-fitted with the inner side wall of the first positioning groove 51.

[0072] By setting the side wall of the second insertion post 8 and the inner side wall of the first positioning groove 51 to a clearance fit, the second insertion post 8 can be installed and disassembled smoothly when it is engaged with the first positioning groove 51, without generating excessive shaking, thus ensuring the stability of the insertion.
