Description

Technical Field

[0001] This invention relates to the field of food processing machines, and in particular to a food processing machine. Background Technology

[0002] Food processors (such as blenders, juicers, soup makers, and multi-functional machines) are widely used in modern kitchens, providing users with convenient food processing capabilities. Traditional food processor containers are typically made of metal (such as stainless steel). While metal has good thermal conductivity and durability, this also means the containers can easily heat up during processing, potentially causing burns upon direct contact and posing a safety hazard. Although some products add partial plastic parts to the outside of the container to improve grip, these parts are often fixed to the metal structure, covering only a small area and failing to insulate against heat. Most of the exposed surface of the container remains metal, resulting in limited overall heat protection. Even with careful operation, accidental contact is still possible. This design presents a potential safety hazard and increases the psychological burden of use, especially in households with children.

[0003] Traditional metal containers often require overall cleaning, but due to their fixed structure, it's difficult to thoroughly clean corners and crevices. Their plastic parts are typically fixed to the metal with screws or clips, making it easy for water to seep into the joints during cleaning, leading to rust or loosening. Furthermore, plastic materials may undergo chemical changes when cleaned at high temperatures or with chemical cleaners, easily turning white, aging, or deforming, and even developing surface cracks, making the container appear old. This whitening and aging not only reduces the product's appearance and affects its aesthetics but also misleads users into believing the product is of poor quality, thus shortening its actual lifespan.

[0004] Furthermore, food containers are typically equipped with lids that can be closed to create a sealed space, preventing food spoilage or leakage. To ensure a tight seal, the lid usually has a locking mechanism, which is locked or unlocked by rotation. For example, the user first places the lid downwards onto the container body, then rotates the lid to a specific position, causing the locking mechanism (such as a snap or protrusion) to engage with the locking switch (such as a groove or button) on the container body. To open the lid, the user first rotates the lid to unlock it, then lifts it upwards. In traditional container lid structures, a sealing ring (usually made of elastic materials such as rubber or silicone) is fixed to the inside or periphery of the lid to ensure a tight seal with the opening edge of the container body. However, this design has a significant drawback: when the lid is rotated to lock or unlock, the sealing ring rotates along with the lid, creating sliding friction with the surface of the container body. Because the sealing ring is made of a soft material and has a large contact area, this friction results in significant rotational resistance, making opening and closing difficult, especially for elderly users or those with less strength. Meanwhile, with prolonged use, the sealing ring is prone to wear, aging, or deformation due to frequent friction. This not only affects the sealing effect, leading to leakage or decreased sealing performance, but also increases replacement and maintenance costs. Furthermore, the friction during rotation can cause difficulties in operating the container cap, or even damage the container itself, reducing the overall durability of the product. To address these issues, the industry has made some attempts at improvement, such as optimizing the sealing ring material or reducing the contact area, but these have not fundamentally solved the problem of the sealing ring rotating with the user.

[0005] Therefore, a new technical solution needs to be researched to address the above problems. Summary of the Invention

[0006] In view of this, the present invention addresses the deficiencies of the existing technology, and its main objective is to provide a food processor that improves product performance and extends service life through a double-layer structure and a separable inner liner, thereby meeting users' diverse needs for safety, convenience, and aesthetics, and effectively solving the shortcomings of traditional food processor containers in terms of safety, cleaning, and durability.

[0008] As a preferred embodiment, a heat insulation cover is provided below the sealing cover of the metal bottom wall, and an inner cavity is formed between the heat insulation cover and the metal bottom wall. The heating unit is disposed in the inner cavity, and an electrical connection port is provided at the bottom of the heat insulation cover, which is connected to the heating unit. A second clearance through hole is provided on the insulating bottom wall, and the electrical connection port is exposed at the second clearance through hole.

[0009] As a preferred embodiment, a locking switch is provided on the outer periphery of the cup-shaped body of the insulating shell corresponding to the upper opening of the take-up and put-out cavity, and a distance is maintained between the upper end of the metal inner liner and the locking switch.

[0010] As a preferred embodiment, the insulating housing includes a separately assembled cylindrical shell, a base, a handle accessory, and a top ring. The first clearance through hole is provided on the base. The cylindrical shell is fitted around the outer periphery of the base. A trigger switch and a safety push rod are provided corresponding to the locking switch. The trigger switch is provided on the base. The upper end of the safety push rod is located at the locking switch, and the lower end extends toward the trigger switch. The top ring is located above the safety push rod.

[0011] As a preferred embodiment, the lower end of the safety push rod extends with an oblique portion, wherein the lower end of the safety push rod has widened protrusions on both the inner and outer sides, and the widened protrusions on both the inner and outer sides and the lower end of the safety push rod together constitute the starting end of the oblique portion extension, and the upper end of the oblique portion is integrally connected to the starting end of the oblique portion extension.

[0012] As a preferred embodiment, the container lid includes: The outer ring cover has a locking trigger part on its outer ring side and a first rotating adapter part on its inner ring side. The inner cover has a second rotating adapter on its outer periphery; the second rotating adapter and the first rotating adapter are horizontally rotatably connected, so that the outer cover is horizontally rotatably arranged around the outer periphery of the inner cover. A sealing ring is disposed on the inner cover and is spaced apart from the outer cover; the sealing ring has an outwardly exposed annular sealing end.

[0013] As a preferred embodiment, the sealing ring is fitted onto the outer periphery of the inner cover body corresponding to the lower part of the second rotating adapter.

[0014] As a preferred embodiment, the inner cover has an integral, radially outwardly extending reinforcing protrusion on its outer periphery corresponding to the lower part of the second rotating adapter. The number of reinforcing protrusions is one or two or more with vertical spacing. The sealing ring is fitted onto the outer periphery of the inner cover corresponding to the reinforcing protrusion.

[0017] Compared with the prior art, the present invention has obvious advantages and beneficial effects. Specifically, as can be seen from the above technical solution, it mainly achieves multiple technical effects through the combination structure of the insulating shell and the metal inner liner. First, the insulating shell is composed of insulating peripheral sidewalls and insulating bottom wall, forming a cavity for taking out and putting in, effectively isolating heat, preventing users from being burned during use, and improving safety. Second, the removable design of the metal inner liner makes it easy for users to take it out for cleaning separately (such as putting it in a dishwasher), avoiding the problem of aging or whitening of the insulating shell caused by overall cleaning, and extending the product life. Moreover, the first transmission head set in the center of the metal bottom wall can rotate horizontally and seal, which not only ensures the stability of power transmission, but also prevents food leakage. At the same time, the first clearance through hole allows the lower end of the first transmission head to extend, which is convenient for docking with the external drive device, realizing the efficient connection between the container and the food processor body. Furthermore, by designing the container lid to include an outer ring cover, an inner cover, and a sealing ring, with a locking trigger on the outer ring side of the outer ring cover, the outer ring cover is horizontally rotatable around the outer periphery of the inner cover, and the sealing ring is disposed on the inner cover, maintaining a distance from the outer ring cover, so that when the outer ring cover rotates, the inner cover and the sealing ring do not move accordingly, effectively avoiding friction between the sealing ring and the container body, and achieving easy opening and closing and a long-lasting seal.

Detailed Implementation

[0020] Please refer to Figures 1 to 17 As shown, it illustrates the specific structure of an embodiment of the present invention.

[0021] In the description of this invention, it should be noted that the terms "upper", "lower", "left", "right", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limiting this invention.

[0022] A food processor includes a main body 100 and a food container 200, and is usually also equipped with a juicing component, a stirring blade, a vegetable cutting component, a steamer component, a stirring lid component, a cooking lid component, etc., so that the food processor has multiple functions such as steaming, stirring, cutting vegetables, and juicing, making it a multi-purpose machine with a wide range of applications.

[0023] The food container 200 includes a container body 201 and a detachable container lid 23 that fits onto the top of the container body 201. The container body includes an insulating outer shell 21 and a metal inner liner 22. The insulating outer shell 21 has a cup-shaped body. A handle is provided around the cup-shaped body of the insulating outer shell 21, allowing the user to easily hold and move the container. The insulating peripheral walls and insulating bottom walls of the cup-shaped body form an open-top retrieval cavity A. A first clearance through hole A1 is provided in the center of the insulating bottom wall, penetrating the retrieval cavity A vertically. An annular boss 211 is provided on the insulating bottom wall surrounding the first clearance through hole A1; the metal inner liner 22 has an open-top food receiving cavity B formed by an integral metal peripheral wall and a metal bottom wall, which is roughly similar in shape to the loading and unloading cavity A. Typically, the metal inner liner 22 is made of stainless steel; a first transmission head 2001 is provided at the center of the metal bottom wall, and a mounting hole 226 is provided at the center of the metal bottom wall for mounting and positioning the first transmission head 2001. Bearings, seals, etc., are also provided at the mounting hole 226 to provide support for the first transmission head 2001. The first transmission head 2001 is horizontally rotatable and sealed relative to the metal bottom wall. The upper end of the first transmission head 2001 protrudes from the upper side of the metal bottom wall for detachable connection of the juicing assembly, stirring blade, or vegetable cutting assembly and other knife accessories 24. The lower end of the first transmission head 2001 protrudes from the lower side of the metal bottom wall. A heating unit 23 is integrated on the metal inner liner. The metal inner liner 22 is removable and located in the removal and placement cavity A of the insulating outer shell 21. The lower end of the first transmission head 2001 extends into the first clearance through hole A1.

[0024] This double-layered food container is heat-resistant, and the metal inner liner 22 can be removed for separate cleaning, such as in a dishwasher. The insulating outer shell 21 is made of plastic and does not require washing, preventing it from turning white and showing its age. Traditional food containers have a metal main body with only partial plastic sections on either side of the locking switch for mounting components like push rods. These plastic sections are fixed to the metal main body, leaving most of the exposed surface as metal, which is prone to getting hot. Furthermore, the plastic parts are not durable and easily turn white and show signs of wear during cleaning, affecting the appearance of the food container and consequently its lifespan.

[0025] The main body 100 contains a motor and has a mounting position. A second transmission head 102 is located at the mounting position, and the motor drives the second transmission head 102 via a transmission assembly. A safety switch mechanism is located at the mounting position. A control panel 101 is also located on the main body 100. The position of the control panel 101 is flexible and can generally be located on the top front side of the main body 100 for easy operation and viewing of displayed parameters / modes. The food container 200 is removably located at the mounting position, and the first transmission head 2001 connects to the second transmission head 102. Different juicing components, blending blades, or cutting components and other knife accessories 24 are installed according to different food processing needs. The corresponding container lids also vary, such as blending lids and cooking lids. The locking trigger of the container lid also affects the triggering of the safety push rod 213. Depending on the operating speed set on the control panel 101 or the different modes of triggering the safety switch mechanism via the safety push rod 213, the control panel 101 controls the motor speed accordingly based on the triggered safety switch mechanism mode.

[0026] Several weighing units 104 are installed on the base plate 103 of the main body 100 to weigh the entire food processor. One end of each weighing unit 104 is connected to the base plate 103, and the other end is connected to a support leg 1041, which contacts and positions the unit on the machine's platform. Furthermore, a protective bottom cover 105 is provided at the bottom of the main body 100. The protective bottom cover 105 is detachably installed below the base plate 103. The protective bottom cover 105 has clearance holes 106 corresponding to each support leg 1041, allowing the support legs 1041 to extend downwards. Several upward-extending connecting posts 107 are provided around the periphery of the protective bottom cover 105. Correspondingly, several connecting hole posts 108 are provided on the base plate 103, with inner holes for the connecting posts 107 to extend and be positioned. The protective bottom cover 105 can be easily disassembled for maintenance.

[0027] In this embodiment, the food container 200 has its own heating function. A heat insulation cover 221 is provided under the sealing cover below the metal bottom wall. The heat insulation cover 221 and the metal bottom wall form an inner cavity 222. A heating unit 223 is provided in the inner cavity 222 to heat the metal inner liner 22. An electrical connection port 225 is provided at the bottom of the heat insulation cover 221, and the electrical connection port 225 is connected to the heating unit 223. A second clearance through hole A2 is provided on the insulating bottom wall, and the electrical connection port 225 is exposed at the second clearance through hole A2, which facilitates connection to an external power source and simplifies electrical integration. Here, the heating unit 223 is located directly at the bottom of the metal base wall. The heating unit includes a copper heat pipe and an aluminum heat-conducting plate 224. The materials of the heat pipe and the heat-conducting plate can be changed as needed. The copper heat pipe generates heat when energized, which is then transferred to the aluminum heat-conducting plate 224. The aluminum heat-conducting plate 224 is attached to the bottom of the metal base wall, resulting in a short heat transfer path, achieving efficient and localized heating, reducing heat loss, and improving energy efficiency. At the same time, the heat insulation cover 221 prevents heat from being transferred to the insulating outer shell 21, further enhancing the anti-scalding performance. Therefore, this structure improves the accuracy and safety of heating control and is suitable for various food processing scenarios.

[0028] The metal inner liner 22 has a flange extending outward from the top of its metal peripheral sidewall. Specifically, this flange is manufactured in a ring shape, with its outer periphery folded inward to thicken the edge and prevent scratching. The flange is located above the top of the insulating peripheral sidewall of the insulating outer shell 21, serving a positioning and anti-drop function. This ensures that the metal inner liner 22 will not completely sink into the retrieval cavity during handling, facilitating user gripping and operation. Simultaneously, the flange may provide additional support, reducing direct friction between the metal inner liner 22 and the insulating outer shell 21, reducing wear, and extending lifespan. This structure also enhances the overall stability of the container, preventing accidental displacement of the metal inner liner 22 during movement or use.

[0029] In this embodiment, a locking switch 2011 is provided on the outer periphery of the cup-shaped body of the insulating outer shell 21 corresponding to the upper opening of the take-up and put-down cavity A. For example, two sets of locking switches 2011 are arranged radially symmetrically. The upper end of the metal inner liner 22 is spaced apart from the locking switch 2011 to allow the locking trigger part of the container lid 23 to be screwed in. The locking switch 2011 ensures that the double-layer food container can be firmly locked when installed on the food processor body, preventing accidental loosening or falling off during use, thus improving the stability and safety of the equipment operation. The spaced distance between the upper end of the metal inner liner 22 and the locking switch avoids direct contact, reduces friction and wear, and allows for thermal expansion or tolerance compensation, ensuring that the locking mechanism is flexible and reliable. Special consideration is given to high-speed rotation or vibration environments, enhancing overall reliability.

[0030] The insulating outer shell 21 includes a modularly assembled cylindrical shell 2101, a base 2102, a handle fitting 2103, and a top ring 2104. This modular design facilitates manufacturing, assembly, and maintenance, reducing production costs and complexity. The first clearance through-hole A1 is provided on the base 2102. The cylindrical shell 2101 is fitted onto the outer periphery of the base 2102. A trigger switch 212 and a safety push rod 213 are configured corresponding to the locking switch 2011. The trigger switch 212 is located on the base 2102. The upper end of the safety push rod 213 has a linkage groove 2133 located at the locking switch 2011, and the lower end extends towards the trigger switch 212. The top ring 2104 is located above the safety push rod 213. This structure ensures that the safety switch is triggered when the double-layer food container is not properly locked, preventing accidental motor start-up and improving user safety. The lower end of the safety push rod 213 extends into a sloping portion 2131. The lower end of the safety push rod 213 has two opposite sides with widened protrusions 2130. These widened protrusions 2130 and the lower end of the safety push rod 213 together form the starting end of the sloping portion extension, providing a wider extension reference for the upper end of the sloping portion 2131. The upper end of the sloping portion 2131 is integrally connected to the starting end of the sloping portion extension. This allows the sloping portion 2131 to be designed to be thicker and its tilt angle relative to the horizontal plane to be larger. Thus, when descending the same height, the horizontal displacement distance generated by the trigger switch 212 from the inside out is greater, which is beneficial for the design and layout of product components. Without the widened protrusion 2130, the thickness of the inclined portion would be the same as the thickness of the safety push rod, and a large tilt angle would affect the molding yield. Furthermore, the widened protrusion 2130, located on the outer side of the lower end of the safety push rod 213, has a flat lower end and an outwardly and downwardly extending inclined surface 2134 at its upper end. A corresponding adapting inclined surface 21011 is provided on the base 2102. This inclined surface design improves the movement trajectory of the safety push rod, making its up-and-down movement smoother and reducing the risk of jamming or friction. A groove is pre-reserved above the inclined surface 2134 on the safety push rod 213, and a stop protrusion 2135 is provided above the groove to limit the downward stroke of the safety push rod 213. The lower end of the safety push rod 213 extends downward from the side of the inclined portion 2131, with a guide post 2132. Correspondingly, a guide hole is provided on the base 2102, and the guide post 2132 extends into the corresponding guide hole. Considering balance, it is preferable to provide two sets, located on both sides of the inclined portion 2131, which helps to ensure the movement of the safety push rod 213, prevents skewing or shaking, and improves linkage accuracy and reliability.

[0031] The container lid 23 is designed as an easy-to-rotate and openable container lid structure, comprising: an outer ring lid body 231, an inner lid body 232, and a sealing ring 233. The outer ring lid body 231 is annular, with a locking trigger part 2315 and a foolproof part 2316 on its outer ring side. Two locking trigger parts 2315 are symmetrically arranged, and a first rotation adapter part is provided on its inner ring side. The inner lid body 232 is circular, with a second rotation adapter part on its outer circumference. The second rotation adapter part and the first rotation adapter part are horizontally rotatably connected, allowing the outer ring lid body 231 to be horizontally rotated around the outer circumference of the inner lid body 232. The sealing ring 233 is annular, disposed on the inner lid body 232, and maintains a distance from the outer ring lid body 231. The sealing ring 233 has an outwardly exposed annular sealing end 2331. By rotating and sliding the outer cover and inner cover together, the first rotating adapter and the second rotating adapter are connected, so that the outer cover can rotate independently horizontally while the inner cover and the sealing ring remain stationary.

[0032] In use, the container lid 23 is placed downwards on the container body 201, and the horizontal rotation of the outer ring lid 231 causes the locking trigger part 2315 to rotate to the locking switch 2011 for locking. When the outer ring lid is rotated to lock or unlock, the sealing ring does not rotate, avoiding friction with the container body, significantly reducing operating force and wear. The sealing ring maintains a distance from the outer ring lid to ensure no interference during rotation, further reducing resistance. The annular sealing end is exposed outwards, directly contacting the container body to form a stable seal, improving sealing reliability and the durability of the container lid.

[0033] Furthermore, the first rotating adapter includes an inner ring groove 2314, and correspondingly, the second rotating adapter includes an outer ring protrusion 2323, the outer ring protrusion 2323 extending into the inner ring groove 2314 and the two being horizontally rotatably slidably connected. The cooperation between the inner ring groove and the outer ring protrusion provides a simple and reliable rotating sliding connection method. This structure is easy to injection mold and assemble, reducing production costs. The engagement of the protrusion and the groove ensures smooth rotation of the outer ring cover around the inner ring cover, reducing shaking and jamming, and improving operational stability. At the same time, this design helps maintain the relative position of the outer ring cover and the inner ring cover, preventing the sealing ring from being squeezed or twisted during rotation, thereby extending the life of the sealing ring.

[0034] Furthermore, the first rotating adapter includes an inner ring protrusion 2312, and correspondingly, the second rotating adapter includes an outer ring groove 2325. The inner ring protrusion 2312 extends into the outer ring groove 2325, and the two are horizontally rotatably slidably connected. The cooperation between the inner ring protrusion and the outer ring groove realizes another rotating connection scheme, increasing design flexibility. This structure also ensures smooth rotation of the outer ring cap, and the engagement of the protrusion and the groove can disperse rotational stress and reduce component wear. It is suitable for container caps of different sizes or shapes, improving the versatility and adaptability of the product, while maintaining the advantages of low friction and ease of operation.

[0035] In this embodiment, the first rotating adapter includes an inner ring groove 2314 and an inner ring protrusion 2312. Correspondingly, the second rotating adapter includes an outer ring protrusion 2323 and an outer ring groove 2325. The inner ring groove 2314 is formed by the inner ring protrusion 2312 and an inner ring upper stop edge 2313 located above the inner ring protrusion 2312. The outer ring groove 2325 is formed by the outer ring protrusion 2323 and an outer ring folded edge 2326 located below the outer ring protrusion 2323. For the outer ring cover 231, it has an inner ring through hole 2311. Its inner ring upper stop edge 2313 is integrally connected to the lower end of the inner ring side of the outer ring cover 231 and extends radially inward to form a stop edge structure protruding from the inner circumferential surface of the inner ring through hole 2311. The stop edge can be multiple spaced protrusions, or it can be a continuously extending arc-shaped edge or a circular edge. An axially elongated cylindrical portion is integrally formed extending downward from the lower end of the inner ring side of the outer cover 231. An inner ring protrusion 2312 extends radially inward from the lower end of the inner ring side of the axially elongated cylindrical portion. Similarly, it can be multiple spaced protrusions, or it can be a continuously extending arc-shaped edge or a circular edge. As for the inner cover 232, it has an inner cover main body 2320. The outer ring protrusion 2323 is integrally connected to the top edge of the outer periphery of the inner cover main body 2320. The outer ring folded edge 2326 extends downward from the bottom edge of the outer periphery of the inner cover main body 2320 and then bends outward horizontally to form the outer ring.

[0036] Furthermore, the sealing ring 233 is fitted onto the outer periphery of the inner cover 232 corresponding to the lower part of the second rotating adapter. An integrally formed downward-extending annular extension 2321 is provided on the inner cover 232 corresponding to the lower part of the second rotating adapter. An integrally formed radially outward-extending reinforcing protrusion 2324 is provided on the outer periphery of the inner cover 2322 corresponding to the lower part of the second rotating adapter. The number of reinforcing protrusions 2324 is one, or two or more are spaced vertically. The reinforcing protrusions 2324 are integrally connected to the outer periphery of the extension 2321. The sealing ring 233 is fitted onto the outer periphery of the inner cover 2322 corresponding to the reinforcing protrusions 2324, thus providing a stable mounting base for the sealing ring 233. The radially outward extension of the reinforcing protrusions enhances the structural rigidity and deformation resistance of the inner cover. The single or multiple spaced protrusions can distribute the force, preventing the inner cover from bending under pressure or rotational force, ensuring that the sealing ring always remains in the correct position. This contributes to stable sealing performance over long-term use and improves the overall durability of the container cap. The use of a raised edge as a support point ensures a more secure installation of the sealing ring. This design prevents the sealing ring from sliding or twisting on the inner cover, ensuring that the annular sealing end makes uniform contact with the container body to form an effective seal. At the same time, the reinforced raised edge acts as a guide, facilitating quick installation of the sealing ring and reducing assembly errors.

[0037] In practice, a sealing ring is installed on the reinforced convex edge 2324 of the container cap to form a radial seal.

[0038] Furthermore, the inner cover 232 is provided with a vertically penetrating vent 2322. An vent guide hood 234 is installed above the vent 232 on the inner cover 232. The lower end of the vent guide hood 234 is embedded in a groove on the inner cover 232, and a tight-fitting rubber ring 235 (equivalent to a sealing ring) on ​​the outer periphery of the lower end of the vent guide hood 234 ensures reliable assembly between the vent guide hood 234 and the inner cover 232. The vent guide hood 234 is provided with an vent channel 241 and a side vent hole 2342. A top shielding edge 2343 is provided above the side vent hole 2342 on the vent guide hood 234 to prevent exhaust from rushing upwards. The lower end of the vent channel 241 connects to the upper end of the vent 2322, and the inner side of the side vent hole 2342 connects to the vent channel 241. The vent design allows internal air to escape during sealing or use, preventing pressure buildup that could lead to difficulty closing or seal failure. During heating, cooling, or transport, the vent balances internal and external pressure, preventing container deformation or spillage, thus improving safety and ease of use. In particular, the vent guide shield guides airflow through vent channels and side vents, enabling controlled venting. A top shield prevents liquids, dust, or foreign objects from directly entering the vent, keeping the container's interior clean. This design maintains a seal while venting, preventing contamination or spillage, making it especially suitable for liquid foods or microwave heating applications, enhancing the container's versatility and hygiene.

[0039] The key design feature of this invention lies in its combination of an insulating outer shell and a metal inner liner, achieving multiple technical benefits. First, the insulating outer shell, composed of insulating sidewalls and an insulating bottom wall, forms a cavity for easy access, effectively isolating heat and preventing burns during use, thus enhancing safety. Second, the removable metal inner liner allows for easy removal and cleaning (e.g., placement in a dishwasher), avoiding the aging or whitening of the insulating outer shell caused by overall cleaning, extending product lifespan. Furthermore, the first transmission head, located at the center of the metal bottom wall, can rotate horizontally and seal, ensuring stable power transmission and preventing food leakage. Simultaneously, a first clearance hole allows the lower end of the first transmission head to extend, facilitating docking with an external drive device and achieving efficient connection between the container and the food processor body. The overall structure simplifies the usage process and improves the user experience.

[0040] Furthermore, by designing the container lid to include an outer ring cover, an inner cover, and a sealing ring, with a locking trigger on the outer ring side of the outer ring cover, the outer ring cover is horizontally rotatable around the outer periphery of the inner cover, and the sealing ring is disposed on the inner cover, maintaining a distance from the outer ring cover, so that when the outer ring cover rotates, the inner cover and the sealing ring do not move accordingly, effectively avoiding friction between the sealing ring and the container body, and achieving easy opening and closing and a long-lasting seal.

[0041] The above description is merely a preferred embodiment of the present invention and does not constitute any limitation on the technical scope of the present invention. Therefore, any minor modifications, equivalent changes, and alterations made to the above embodiments based on the technical essence of the present invention shall still fall within the scope of the technical solution of the present invention.
