Food processor with stirring structure

Abstract

This utility model relates to the technical field of household appliances, and proposes a food processor with a stirring structure, including a stirring cup, a micro switch, and a lid assembly. The lid assembly is mounted on the machine body via a positioning and anti-rotation structure of the handle assembly, and a second magnet is provided on the positioning and anti-rotation structure of the lid assembly. When the lid assembly is closed, the second magnet triggers the micro switch to close, enabling the food processor to operate; when it is opened, it automatically cuts off the power. Compared with the existing technology that requires rotating the soundproof cover to trigger the switch, this solution achieves switch control through a simple closing action, which is not only simpler in structure (eliminating the rotation linkage component), but also more convenient to operate (one-step operation), while avoiding poor contact problems caused by incomplete rotation, greatly improving the reliability and safety of use.

Description

Technical Field

[0001] This utility model relates to the technical field of household appliances, specifically to a food processor with a stirring structure. Background Technology

[0002] A food processor is a common kitchen appliance, mainly used for blending, pulverizing, and mixing ingredients, and is widely used in making juices, sauces, and baby food. Because its high-speed rotating blades generate considerable noise during blending, existing technologies typically incorporate a soundproof cover on the lid to reduce operating noise. This soundproof cover extends at least to the upper part of the blending cup to effectively block the outward transmission of noise generated by the high-speed rotation of the blades.

[0003] However, if the user accidentally opens the lid before the blending process has completely stopped, food may splatter or even pose a safety hazard. Therefore, a detection mechanism needs to be designed to ensure that the food processor only starts when the lid is fully closed and immediately cuts off the power when the lid is opened, thereby improving safety.

[0004] To address the aforementioned technical problems, Chinese Patent No. ZL202320807531.6 discloses a safe food processing machine, comprising a main unit with an internal motor, a cup body mounted on the main unit, a soundproof cover covering the cup body, and a safety switch within the main unit for controlling the motor's start and stop. The safety switch is triggered by the soundproof cover. The top of the main unit has a trigger area corresponding to the safety switch and a engagement area offset from the trigger area. The bottom of the soundproof cover has an engagement rib that screws into the engagement area to axially limit the soundproof cover. The engagement rib communicates with the trigger area, allowing it to reciprocate between the trigger area and the engagement area, thus opening and closing the safety switch. When storing the food processing machine, rotating the soundproof cover causes the engagement rib to move, causing it to screw into the engagement groove, thereby securing the soundproof cover. This reduces the risk of the soundproof cover falling to the ground and being damaged when the food processing machine is moved. This food processing machine requires a rotating soundproof cover, which drives the second magnet. When the second magnet rotates to the sensing area of ​​the Hall element, the Hall element senses the magnet, thus starting the motor. This achieves the effect of starting the motor by rotating the soundproof cover, which is cumbersome. If the user accidentally rotates the soundproof cover in the opposite direction, it will cause the cover to rotate in the opposite direction. In addition, the triggering of its safety switch depends on the rotation of the soundproof cover and the mechanical displacement of the spiral ribs. The structure is complex and the operation steps are cumbersome (requiring the soundproof cover to rotate to drive the second magnet to the sensing area of ​​the Hall element). It is also prone to trigger failure due to mechanical wear or misalignment. Utility Model Content

[0005] This invention proposes a food processor with a stirring structure. A precise and sensitive safety control mechanism is formed through the cooperation of a microswitch on the main body and a second magnet on the lid assembly. When the lid assembly is installed on the main body and the stirring cup is closed, the second magnet approaches the microswitch, triggering its closure. This ensures the food processor can only operate when the lid is fully closed. The positioning and anti-rotation structure of the lid and handle assemblies directly positions the relative positions of the second magnet and the microswitch. The switch is triggered simply by closing the lid, simplifying the structure (eliminating the need for a rotating linkage component), improving reliability (reducing the risk of mechanical wear), and enhancing operational convenience (one-step lid-closing trigger). It also avoids the trigger failure problems caused by incomplete rotation or displacement deviation of the screw ribs in existing technologies.

[0006] A food processor with a mixing structure designed for this purpose includes a body equipped with a mixing cup, and the body further includes: A micro switch, used to control the on / off state of the food processor circuit; A lid assembly, which is detachably disposed on the machine body and used to open and close the opening of the mixing cup, and is provided with a second magnet on the lid assembly; A handle assembly is provided with a positioning and anti-rotation structure between the handle assembly and the cover assembly, and a second magnet is correspondingly installed on the positioning and anti-rotation structure of the cover assembly; When the cover assembly is positioned and installed onto the machine body through the positioning and anti-rotation structure and covers the mixing cup, the second magnet approaches the micro switch to trigger the micro switch to close, so that the food processor is in a working state. When the cover assembly is separated from the main body, the second magnet moves away from the micro switch, and the micro switch resets to the off state to cut off the power to the food processor.

[0007] The positioning and anti-rotation structure includes: A positioning groove is provided on the cover assembly; Positioning boss; the positioning boss is located on the handle assembly and the body; The second magnet is installed on the outside of the positioning groove and close to the upper part of the positioning groove. The micro switch is installed on the inside of the positioning boss. When the cover assembly is installed on the machine body, the positioning boss is embedded in the positioning groove, and the second magnet triggers the micro switch accordingly. The positioning groove and the positioning boss are arranged in a corresponding manner to form a unique, foolproof installation structure for mounting the cover assembly on the machine body.

[0008] The cover assembly includes a soundproof cover for covering the upper part and the side of the stirring cup. The side of the soundproof cover is provided with a positioning groove for positioning and mounting on the machine body. The positioning groove extends upward from the bottom of the soundproof cover. The upper part of the positioning groove is provided with a fixing member for fixing the second magnet. The fixing member protrudes outward from the positioning groove and has an installation groove, and the second magnet is installed in the installation groove.

[0009] The handle assembly includes a positioning boss fixed to the body and used for positioning and installing the cover assembly, and the positioning boss has an assembly cavity for installing a micro switch. The handle assembly also includes a handle, with the first end of the handle fixedly connected to the positioning boss and the second end of the handle fixedly connected to the body of the machine body; the cover assembly is provided with an assembly protrusion, which protrudes along the outer side of the cover assembly, and the top of the assembly protrusion is provided with a fixing member for installing the second magnet. When the cover assembly and the handle are assembled, the assembly protrusion and the positioning boss are interlocked to form an anti-misinstallation structure to prevent misassembly from triggering the micro switch to be energized.

[0010] Alternatively, the micro switch can be located on the inside of the handle.

[0011] The micro switch has a first magnet on its metal spring, and the first magnet and the second magnet repel each other. During the closing process of the cover assembly, the second magnet is driven by magnetic repulsion to trigger the micro switch to close.

[0012] The cover assembly has a vent hole for connecting the inner cavity of the mixing cup with the outside of the machine body. When the internal air pressure of the mixing cup exceeds a set threshold, the gas inside the mixing cup is discharged to the outside of the machine body through the vent hole.

[0013] The cover assembly is equipped with an elastic valve plate. In the initial state, the elastic valve plate covers the vent hole to close it. When the internal air pressure of the mixing cup exceeds a set threshold, the gas pushes open the elastic valve plate to open the vent hole, thereby venting the gas inside the mixing cup.

[0014] The cover assembly includes a soundproof cover and an inner cover located inside the soundproof cover. A connecting component is provided between the soundproof cover and the inner cover. The soundproof cover has a first mounting groove, and the inner cover has a second mounting groove. The connecting component is installed to the first mounting groove and the second mounting groove so that the soundproof cover and the inner cover are fixedly connected by the connecting component. The vent is located on the top of the connecting assembly, which has a mounting hole. The elastic valve plate has a positioning post that inserts into the mounting hole, and the positioning post has a buckle that engages with the inside of the mounting hole.

[0015] The outer side of the inner cover is provided with a sealing element for abutting against the inner wall of the mixing cup.

[0016] The machine body is provided with a cup holder, which is detachably connected to the mixing cup. The mixing cup is open at both ends and has a hollow structure. A heating plate is provided inside the cup holder, and a heating tube is provided at the bottom of the heating plate. A sealing ring is provided between the cup holder and the heating plate to seal the gap between them. When the cup holder and the stirring cup are installed, the bottom of the stirring cup abuts against the upper part of the sealing ring to form a sealing fit. The sealing ring is sleeved on the outside of the heating plate, and the upper surface of the heating plate forms the inner bottom wall of the stirring cup.

[0017] The electrical cavity inside the machine body contains a control circuit board and a stirring motor electrically connected to the control circuit board. The drive shaft of the stirring motor passes upward through the heating plate and is connected to the stirring blade. The drive shaft of the stirring motor is provided with a sealing sleeve for sealing the perforation of the heating plate. The outer side of the machine body is provided with a handle, and the handle is provided with a wiring groove for arranging wires. The wiring groove is connected to the electrical cavity, and one end of the micro switch is electrically connected to the control circuit board in the electrical cavity through a wire.

[0018] The beneficial technical effects of this utility model are as follows: A precise and sensitive safety control mechanism is formed through the interaction of a microswitch on the main body and a second magnet on the lid assembly. When the lid assembly is installed on the main body and the blender cup is closed, the second magnet approaches the microswitch, triggering its closure and ensuring that the blender can only operate when the lid is fully closed. When the lid assembly is separated from the main body, the second magnet moves away, causing the microswitch to reset and disconnect, immediately cutting off the power. Even if the lid is accidentally opened during operation, the power is quickly cut off to prevent the blades from continuing to rotate and causing injury, greatly improving safety. In addition, the non-contact triggering method of the second magnet and microswitch is more durable than mechanical contact structures, reducing malfunctions caused by wear and extending the service life of the detection mechanism. At the same time, the simple structure eliminates the need for complex transmission components, reducing the probability of failure and ensuring the stability and reliability of control.

[0019] The relative positions of the second magnet and the micro switch are directly positioned by the positioning and anti-rotation structure of the cover assembly and the handle assembly. The switch can be triggered by simply closing the cover, which simplifies the structure (eliminating the rotation linkage component), improves reliability (reducing the risk of mechanical wear) and ease of operation (one-step closing triggering), and avoids the triggering failure problem caused by incomplete rotation or displacement deviation of the screw rib in the prior art.

[0031] The technical solutions of the present utility model will be clearly and completely described below with reference to the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. In order to make the above-mentioned objects, features and advantages of the present application more apparent and understandable, many specific details are set forth in the following description in order to provide a full understanding of the present application. However, the present application can be implemented in many other ways different from those described herein, and those skilled in the art can make similar improvements without departing from the spirit of the present application. Therefore, the present application is not limited to the specific embodiments disclosed below.

[0032] See Figures 1-10 A food processor with a mixing structure includes a body 1 equipped with a mixing cup 2, and the body 1 further includes: Micro switch 4, the micro switch 4 is used to control the on / off state of the food processor circuit; The cover assembly 3 is detachably disposed on the machine body 1 and used to open and close the opening of the stirring cup 2, and the cover assembly 3 is provided with a second magnet 5; A handle assembly is provided with a positioning and anti-rotation structure 6 between the handle assembly and the cover assembly 3, and a second magnet 5 is correspondingly installed on the positioning and anti-rotation structure of the cover assembly 3. When the cover assembly 3 is positioned and installed on the body 1 by the positioning and anti-rotation structure 6 and covers the mixing cup 2, the second magnet 5 approaches the micro switch 4 to trigger the micro switch 4 to close, so that the food processor is in a working state. When the cover assembly 3 is separated from the body 1, the second magnet 5 moves away from the micro switch 4, and the micro switch 4 resets to the off state to cut off the power to the food processor.

[0033] A precise and sensitive safety control mechanism is formed through the cooperation of the microswitch 4 on the main body 1 and the second magnet 5 on the lid assembly 3. When the lid assembly 3 is installed on the main body 1 via the positioning anti-rotation structure 6 and closes the mixing cup 2, the second magnet 5 approaches the microswitch 4 to trigger its closure, ensuring that the blender can only operate when the lid is fully closed. When the lid assembly 3 is separated from the main body 1, the second magnet 5 moves away, causing the microswitch 4 to reset and disconnect, immediately cutting off the power. Even if the lid is accidentally opened during blender operation, the power can be quickly cut off to prevent the blades from continuing to rotate and causing injury, greatly improving safety. In addition, the non-contact triggering method of the second magnet and the microswitch is more durable than mechanical contact structures, reducing malfunctions caused by wear and extending the service life of the detection mechanism. At the same time, the simple structure eliminates the need for complex transmission components, reducing the probability of failure and ensuring the stability and reliability of control.

[0034] The relative positions of the second magnet and the micro switch are directly positioned by the positioning and anti-rotation structure 6 of the cover assembly 3 and the handle assembly. The switch 4 can be triggered by simply closing the cover, which simplifies the structure (eliminating the rotation linkage component), improves reliability (reducing the risk of mechanical wear) and ease of operation (one-step closing triggering), and avoids the triggering failure problem caused by incomplete rotation or displacement deviation of the screw rib in the prior art.

[0035] The positioning and anti-rotation structure 6 includes: Positioning groove 7, which is provided on cover assembly 3; Positioning boss 8; the positioning boss 8 is located on the handle assembly and the body 1; The second magnet 5 is installed on the outside of the positioning groove 7 and close to the upper position of the positioning groove 7. The micro switch 4 is installed on the inside of the positioning boss 8. When the cover assembly 3 is installed on the body 1, the positioning boss 8 is embedded in the positioning groove 7, and the second magnet 5 triggers the micro switch 4 accordingly. The positioning groove 7 and the positioning boss 8 are arranged in a corresponding manner to form a unique, foolproof installation structure for mounting the cover assembly 3 on the body 1.

[0036] Since the positioning groove 7 and the positioning boss 8 are in one-to-one correspondence and have a unique mating relationship, the assembly between the body 1 and the cover assembly 3 does not require rotational alignment. The positioning groove 7 and the positioning boss 8 work together to prevent foolproof installation and avoid misoperation.

[0037] The matching design of the positioning groove 7 and the positioning boss 8 effectively prevents relative rotation between the lid assembly 3 and the body 1 during installation. This constraint ensures that after the lid assembly 3 is installed, the second magnet 5 is always precisely aligned with the micro switch 4, preventing the second magnet from shifting due to lid rotation, and thus preventing the micro switch 4 from being falsely triggered or not triggered properly. When the lid assembly 3 is installed on the body 1, the positioning boss 8 is embedded in the positioning groove 7, which not only achieves reliable anti-rotation but also provides a clear positioning guide for the installation of the lid assembly 3, making it convenient for users to quickly and accurately install the lid assembly 3 and reducing safety hazards caused by installation deviations. At the same time, this structure enhances the stability of the connection between the lid assembly 3 and the body 1, preventing the lid assembly 3 from loosening or shifting in the vibration environment of the food processor during operation, ensuring that the cooperation between the second magnet 5 and the micro switch 4 is always precise, and further improving the reliability of the safety control mechanism.

[0038] If the lid assembly 3 rotates when the body 1 is working, and the food processor control circuit relies on the micro switch 4 to control the on / off state and detect whether the lid assembly 3 is installed in place, then the detection will fail and the food processor will not work properly.

[0039] The cover assembly 3 includes a soundproof cover 9 for covering the upper part and the side of the stirring cup 2. The side of the soundproof cover 9 is provided with a positioning groove 7 for positioning and mounting on the body 1. The positioning groove 7 extends upward from the bottom of the soundproof cover 9. The upper part of the positioning groove 7 is provided with a fixing member 36 for fixing the second magnet 5. The fixing member 36 protrudes outward from the positioning groove 7 and is provided with a mounting groove 10, and the second magnet 5 is installed in the mounting groove 10.

[0040] The shape of the fixing member 36 is cylindrical, square or other shapes; the fixing member 36 is set on the upper part of the positioning groove 7. Without affecting the insertion and cooperation between the positioning groove 7 and the positioning boss 8, the second magnet 5 located on the fixing member 36 can cooperate with the micro switch 4 to successfully complete the function of the safety detection structure.

[0041] The soundproof cover 9 covers the upper and sides of the blending cup 2, effectively blocking the noise generated by the high-speed operation of the blades from propagating outwards, significantly reducing noise pollution during use and improving the user experience. The mounting groove 10 on the outer side of the soundproof cover 9 is used to fix the second magnet 5. Simultaneously, the positioning groove 7 on the soundproof cover 9 cooperates with the positioning structure of the main body 1, ensuring precise installation of the cover assembly 3 while further enhancing the alignment between the second magnet 5 and the micro switch 4, preventing installation deviations of the cover assembly 3 from affecting the safety control function. Furthermore, the second magnet 5 is located on the outside of the soundproof cover 9, not contacting the food inside the blending cup 2, and effectively utilizing the installation space of the soundproof cover 9. Only one second magnet 5 is needed to trigger the micro switch 4, eliminating the need for additional mechanical transmission structures and simplifying the structure of the food processor.

[0042] The handle assembly includes a positioning boss 8 fixed on the body 1 and used for positioning and installing the cover assembly 3. The positioning boss 8 is provided with an assembly cavity 11 for installing the micro switch 4. The handle assembly also includes a handle 12, the first end of which is fixedly connected to the positioning boss 8, and the second end of which is fixedly connected to the body of the body 1; the cover assembly 3 is provided with an assembly protrusion 43, which protrudes along the outer side of the cover assembly 3, and the top of the assembly protrusion 43 is provided with a fixing member 36 for installing the second magnet 5. When the cover assembly 3 and the handle 12 are assembled, the assembly protrusion 43 and the positioning boss 8 are inserted into each other to form an anti-misinstallation structure to prevent misassembly from triggering the micro switch 4 to be energized; both the assembly protrusion 43 and the positioning boss 8 are provided on the soundproof cover 9.

[0043] Alternatively, the micro switch 4 can be located on the inside of the handle 12.

[0044] The metal spring of the micro switch 4 is provided with a first magnet 41, which repels the second magnet 5. During the closing process of the cover assembly 3, the second magnet 5 is driven by magnetic repulsion to trigger the micro switch 4 to close.

[0045] When the micro switch 4 is installed in the assembly cavity 11 of the positioning boss 8, the assembly cavity 11 provides good protection for the micro switch 4, preventing external collisions, dust, or liquids from directly contacting the micro switch 4, reducing damage caused by external factors, and extending its service life. Simultaneously, the positioning boss 8 matches the positioning groove 7 of the cover assembly 3, ensuring that when the cover assembly 3 is installed in place, the second magnet 5 can accurately approach the micro switch 4 in the assembly cavity 11, guaranteeing accurate triggering. The design of fixing the micro switch 4 inside the handle 12 utilizes the structure of the handle 12 to provide a natural protective space for the micro switch 4. The stable structure of the handle 12, with its first end fixed to the positioning boss 8 and the second end fixed to the body 1, effectively utilizes the space of the positioning boss 8. The micro switch 4 and the handle 12 are integrated and fixedly mounted on the positioning boss 8. Furthermore, the wiring groove 31 inside the handle 12 facilitates wire arrangement, keeping the wiring neat and orderly, preventing exposed or tangled wires, reducing the risk of circuit failure, and improving the overall structural safety and reliability.

[0046] When the cover assembly 3 is positioned and installed on the body 1 by the positioning and anti-rotation structure 6 and covers the mixing cup 2, the second magnet 5 approaches the first magnet 41 to trigger the micro switch 4 to close, so that the food processor is in a working state. When the cover assembly 3 is separated from the body 1, the second magnet 5 moves away from the first magnet 41, and the micro switch 4 resets to the off state to cut off the power to the food processor.

[0047] The second magnet 5 on the cover assembly 3 and the first magnet 41 on the micro switch 4 can be multiple. When multiple magnets are set, they can be stacked. The same poles of each magnet are stacked in the same direction. Each magnet can also be stacked with opposite poles.

[0048] The cover assembly 3 has a vent 13 for connecting the inner cavity of the stirring cup 2 with the outside of the machine body 1. When the internal air pressure of the stirring cup 2 exceeds a set threshold, the gas inside the stirring cup 2 is discharged to the outside of the machine body 1 through the vent 13.

[0049] When blending ingredients in a food processor, especially those containing liquids or prone to producing gas, the internal pressure of the blending cup 2 may increase due to the mixing and friction of the ingredients. The vent 13 allows the internal gas to escape to the outside of the machine body 1 when the pressure exceeds a set threshold. This prevents excessive pressure inside the blending cup 2 from forcibly opening the lid assembly 3, thus preventing food from being ejected with the gas and causing safety hazards and food waste. Simultaneously, maintaining pressure balance helps preserve a stable environment inside the blending cup 2, allowing the ingredients to be blended more evenly and improving the blending effect.

[0050] The cover assembly 3 is provided with an elastic valve plate 14. In the initial state, the elastic valve plate 14 covers the vent hole 13 to close the vent hole 13. When the internal air pressure of the stirring cup 2 exceeds the set threshold, the gas pushes open the elastic valve plate 14 to open the vent hole 13, thereby venting the gas inside the stirring cup 2.

[0051] The elastic valve plate 14 initially covers the vent hole 13, effectively sealing the mixing cup 2 and preventing external air from entering. This provides pressure maintenance and prevents external dust and impurities from contaminating the food through the vent hole 13. When the internal pressure of the mixing cup 2 exceeds a set threshold, the gas automatically opens the elastic valve plate 14 to release air through the vent hole 13, eliminating the need for manual operation. This rapid and sensitive response quickly reduces internal pressure, preventing safety risks associated with excessive pressure. Once the pressure returns to normal, the elastic valve plate 14 automatically retracts, closing the vent hole 13 and restoring the sealed pressure-maintaining state, ensuring continuous mixing. This automatic opening and closing design not only enhances ease of use but also ensures precise pressure control. The elastic valve plate 14 is simple in structure, low in cost, easy to install, and can operate stably for extended periods, improving product reliability and durability.

[0052] In this embodiment, the vent hole 13 can be provided separately or a design combining the vent hole 13 and the elastic valve plate 14 can be adopted.

[0053] The cover assembly 3 includes a soundproof cover 9 and an inner cover 15 located inside the soundproof cover 9. A connecting assembly 16 is provided between the soundproof cover 9 and the inner cover 15. The soundproof cover 9 is provided with a first mounting groove 17, and the inner cover 15 is provided with a second mounting groove 18. The connecting assembly 16 is installed to the first mounting groove 17 and the second mounting groove 18 so that the soundproof cover 9 and the inner cover 15 are fixedly connected by the connecting assembly 16. The vent 13 is provided on the top of the connecting component 16. The top of the connecting component 16 is provided with a mounting hole. The elastic valve plate 14 is provided with a positioning post 19 that is inserted into the mounting hole. The positioning post 19 is provided with a buckle 20 that is fastened to the inside of the mounting hole.

[0054] The soundproof cover 9 and the inner cover 15 are fixedly connected by a connecting component 16. The connecting component 16 is installed in the first assembly groove 17 and the second assembly groove 18, ensuring a firm connection between the soundproof cover 9 and the inner cover 15. This prevents loosening or separation during use or installation and removal, and enhances the overall structural strength of the cover assembly 3. The vent 13 is located on the top of the connecting component 16, in a reasonable position to facilitate gas discharge. The elastic valve plate 14 is inserted into the mounting hole through the positioning post 19 and fastened inside the mounting hole by the inverted buckle 20, ensuring that the elastic valve plate 14 is firmly installed and not easy to fall off, thus ensuring the stability of the air pressure control function. This assembly method is not only convenient to install, but also facilitates later maintenance or replacement of the elastic valve plate 14. At the same time, the combined structure of the soundproof cover 9 and the inner cover 15 achieves sound insulation through the soundproof cover 9 and ensures the sealing of the stirring cup 2 through the inner cover 15. The functional areas are clearly defined and work together, improving the overall performance of the cover assembly 3.

[0055] The connecting assembly 16 includes a lower connecting member 31 and an upper connecting member 32. The soundproof cover 9 and the inner cover 15 are respectively connected to the lower connecting member 31. The upper connecting member 32 is provided with a plug-in part that inserts into the inner cavity of the lower connecting member 31. The plug-in part of the upper connecting member 32 is provided with a venting channel 33 that communicates with the inner cavity of the stirring cup 2. The lower connecting member 31 is provided with a connecting block. The connecting block is provided with a number of vent holes that are spaced apart. The vent holes are aligned with the venting channel 33 and communicate with the inner cavity of the stirring cup 2.

[0056] The soundproof enclosure 9 has a first mounting groove, and the lower connector 31 has a connecting ring that inserts into the mounting groove. The inner cover 15 has a second mounting groove, and the lower part of the lower connector 31 is inserted into the second mounting groove of the inner cover 15. The lower part of the lower connector 31 also has a sealing component that abuts against the inner side of the second mounting groove. The upper connector 32 and the lower connector 31 can be fastened together by threads, snaps, or interference fit.

[0057] The outer side of the inner cover 15 is provided with a sealing element 21 for abutting against the inner wall of the mixing cup 2.

[0058] The sealing element 21 abuts against the inner wall of the mixing cup 2, which can effectively enhance the sealing between the inner cover 15 and the mixing cup 2, and prevent water vapor from overflowing from the gap between the two to the inner side of the soundproof cover 9 during the mixing and heating process.

[0059] The machine body 1 is provided with a cup holder 22, which is detachably connected to the stirring cup 2. The stirring cup 2 is open at both ends and has a hollow structure. The cup holder 22 is provided with a heating plate 23, and a heating tube 24 is provided at the bottom of the heating plate 23. A sealing ring 25 is provided between the cup holder 22 and the heating plate 23 to seal the gap between them. When the cup holder 22 and the stirring cup 2 are installed, the bottom of the stirring cup 2 abuts against the upper part of the sealing ring 25 to form a sealing fit. The sealing ring 25 is sleeved on the outside of the heating plate 23, and the upper surface of the heating plate 23 forms the inner bottom wall of the stirring cup 2.

[0060] The cup holder 22 is detachably connected to the blending cup 2 (specifically, by thread), allowing users to easily remove the blending cup 2 for cleaning or to access ingredients, thus improving usability. The heating plate 23 inside the cup holder 22 and the heating element 24 at the bottom enable the food processor to heat directly into the blending cup 2, expanding its application scenarios and enhancing its practicality. A sealing ring 25 is positioned between the cup holder 22 and the heating plate 23, effectively sealing the gap between them to prevent liquid from the blending cup 2 from seeping into the machine body 1, protecting electrical components from liquid damage and reducing the risk of short circuits and other malfunctions. When the cup holder 22 and blending cup 2 are installed, the bottom of the blending cup 2 abuts against the upper part of the sealing ring 25 to form a sealed fit, further strengthening the overall sealing. The upper surface of the heating plate 23 serves as the inner bottom wall of the blending cup 2, making the structure of the blending cup 2 more compact. During heating, heat can be directly transferred to the ingredients, improving heating efficiency and uniformity. The temperature resistance of the sealing ring 25 ensures long-term stable operation under heating conditions, extending the product's lifespan.

[0061] The electrical cavity 27 inside the body 1 is equipped with a control circuit board and a stirring motor 28 electrically connected to the control circuit board. The drive shaft of the stirring motor 28 passes upward through the heating plate 23 and is connected to the stirring blade 29.
