DETAILED DESCRIPTION
[0020] In order to make the purpose, technical scheme and advantages of the present application more clear, the present application will be further described in detail below with reference to the drawings, and the described embodiments should not be regarded as limitation of the present application, all other embodiments obtained by the person skilled in the art without creative labor shall belong to the protection scope of the present application.

It is understood that “first, second, third, ……” may be interchanged in a specific order or sequence where permitted, so that the embodiments of the invention described herein can be implemented in an order other than that illustrated or described herein.
[0023] It should be understood that the directional descriptions "above", "below", "outside" and "inside" involved in the embodiments of the present invention refer to the directional directions under normal use. The "left" and "right" directions refer to the left and right directions shown in the corresponding schematic diagrams, which can be the left and right directions under normal use or not.
[0024] It should be noted that the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a process, method, article, or apparatus. Unless otherwise specified, an element defined by the phrase "comprising one..." does not exclude the presence of other identical elements in the process, method, article, or apparatus that includes that element. "A plurality of" means two or more.
[0025] Unless otherwise defined, all technical and scientific terms used in the embodiments of this invention have the same meaning as commonly understood by one of ordinary skill in the art. The terminology used in the embodiments of this invention is for descriptive purposes only and is not intended to limit the invention.
[0026] like Figure 1 and Figure 2 As shown in the figure, the multi-head cooking machine 1 provided in this embodiment of the invention can automatically stir ingredients for cooking. "Multi-head" refers to a combination of at least two cooking stations and two stirring devices, which enables the simultaneous cooking of at least two dishes at different cooking stations, thereby improving the efficiency of food preparation.
[0027] like Figure 1 and Figure 2As shown, the multi-head cooking machine 1 includes a lower shell 11, a top shell 12, a pot body 13, a stirring assembly 14, and a heating assembly 15. The lower shell 11 has an internal receiving space 111. The top shell 12 is connected to the top surface of the lower shell 11. An installation cavity 10 is formed on the top surface of the lower shell 11 and / or inside the top shell 12. The pot body 13 is used to hold food, and at least two pot bodies 13 are provided to meet the need for cooking at least two dishes simultaneously. The stirring assembly 14 is used to stir the food in the pot body 13. At least two stirring assemblies 14 are provided, each movably connected to the top shell 12, and reciprocating in the vertical direction relative to the pot body 13. The number of stirring assemblies 14 is not less than the number of pot bodies 13, so that when multiple pot bodies 13 are cooking simultaneously, there is a stirring assembly 14 to automatically stir the food in each pot body 13. The heating element 15 is used to heat the corresponding pot body 13. The heating element 15 is disposed in the mounting cavity 10 and has a number of heating positions 150 not less than the number of pot bodies 13, so that when multiple pot bodies 13 are used to cook food at the same time, there are corresponding heating positions 150 to heat each pot body 13. The accommodating space 111 and the mounting cavity 10 are arranged in layers along the vertical direction, so that the parts placed inside do not interfere with each other, and the vertical space is utilized for storage without increasing the horizontal dimension, which is conducive to the miniaturization of the overall size of the cooking machine.
[0028] Specifically, the lower housing 11 forms the base of the equipment. It can be constructed with a frame structure made of materials such as aluminum or stainless steel, and features a hollow internal space 111. This space primarily houses the core electrical components necessary for equipment operation, including the control system, power module, and motor for driving the stirring assembly 14 to lift or lower. It can also accommodate subsystems such as storage tanks (for automatically adding oil, water, and seasonings). By using the internal space 111, the aforementioned non-direct cooking components can be centrally housed within the lower housing 11, lowering the overall center of gravity and improving stability. Furthermore, it isolates the components from the upper heat source, preventing high-temperature interference and promoting long-term reliable operation of the electrical components. The side walls of the lower housing 11 can be equipped with concealed grid air ducts communicating with the internal space 111, facilitating airflow within the space. Locking casters can be installed at the bottom of the lower housing 11 for easy adjustment of the overall position.
[0029] Specifically, the top shell 12, serving as a platform for cooking functions, can be mounted on the top surface of the lower shell 11 via screw connection, snap-locking, or sliding rail embedding. A mounting cavity 10 is formed on the top surface of the lower shell 11 and / or within the top shell 12. This mounting cavity 10 can be formed by combining with the top surface of the lower shell 11, or by setting the top shell 12 as a box-like structure with a base plate to form the mounting cavity 10. Alternatively, it can be directly formed on the top surface of the lower shell 11, with the top shell 12 covering the mounting cavity 10 after closing. The mounting cavity 10 is used to accommodate high-temperature modules such as the heating element 15, enabling direct heating of the pot body 13. By vertically layering the accommodating space 111 (within the lower shell 11) and the mounting cavity 10 (within the top shell 12), not only is installation space provided for the necessary components of the equipment, but the required floor space of the cooking machine is also primarily determined by the projected dimensions of the top shell 12, thereby significantly reducing the horizontal floor space occupied by the equipment and eliminating the need for extensive installation space.
[0030] Specifically, the pot body 13 is used to hold food, and at least two pot bodies 13 are provided to meet the need for cooking at least two dishes simultaneously. The pot bodies 13 can be arranged in a straight line, an "L" shape, or a surrounding layout to accommodate different top shell 12 shapes and user habits. The pot bodies 13 are typically made of stainless steel and are detachable from the top shell 12 for easy cleaning. The bottom of the pot body 13 fits tightly with the heating element 15, creating a suitable heating area and good heating efficiency. At least two stirring elements 14 are also provided to match the pot body 13. Each stirring element 14 is movably connected to the top shell 12 via a hinge shaft or linkage mechanism and can reciprocate upwards or downwards relative to the top shell 12 in the vertical direction. In this way, the stirring component 14 can descend into the pot body 13 during operation to stir the ingredients inside the pot body 13, and rise upward when adding ingredients, unloading, or when idle. This not only makes it possible to make room for operation above the pot body 13, facilitating operations such as cleaning the pot body 13 or the stirring component 14, but also avoids interference of the stirring component 14 with the operation process and the potential risk of burns, significantly improving safety and user experience.
[0031] Specifically, the heating element 15 provides a heat source for cooking, at least to heat the corresponding pot body 13. The heating element 15 heats the pot body 13 using electromagnetic heating, thick-film heating, or metal tube infrared heating, etc. The heating element 15 is disposed within the mounting cavity 10 and has at least as many heating positions 150 as the pot bodies 13, ensuring that each pot body 13 can be heated independently and precisely. The "heating position 150" refers to a location on the heating element 15 where a pot body 13 can be placed and heated. By centrally mounting the heating elements within the upper mounting cavity 10, a physical separation is achieved from components (such as electrical switches) located within the receiving space 111. This isolation design effectively prevents cooking heat from being transferred downwards to sensitive electrical components, thereby contributing to the stability and durability of the control system. In some embodiments, each heating position 150 is independently controlled, allowing each pot body 13 to cook at different temperatures and stages simultaneously, maintaining the efficient parallel processing capability of the multi-head cooking machine 1 while achieving a compact structure.
[0032] The multi-head cooking machine 1 provided in this embodiment of the invention includes a lower shell 11, a top shell 12, a pot body 13, a stirring assembly 14, and a heating assembly 15. The lower shell 11 has an internal receiving space 111. The top shell 12 is connected to the top surface of the lower shell 11. An installation cavity 10 is formed on the top surface of the lower shell 11 and / or inside the top shell 12. The pot body 13 is mounted on the top shell 12. The stirring assembly 14 reciprocates vertically relative to the pot body 13 to stir the food inside the pot body 13. The heating assembly 15 is disposed within the installation cavity 10 and is used to heat the pot body 13 to cook the food. By providing at least two pot bodies 13 and a corresponding number of stirring assemblies 14 that can reciprocate vertically relative to the pot bodies 13, multi-tasking cooking functions are ensured, and operation is safe and convenient. Furthermore, by centrally arranging the heating assemblies 15 within the installation cavity 10 and having independent heating positions 150, the necessary heat source is provided while also allowing for individual control of the heating method. Furthermore, by adopting a layered design that integrates the accommodating space 111 and the mounting cavity 10 vertically, the vertical space is utilized for overall integration. This eliminates the need for horizontal expansion to meet the installation space requirements when multiple cooking stations are set up. While meeting the overall installation requirements, the overall footprint of the equipment can be significantly reduced, improving the applicability and placement flexibility of the cooking machine in compact kitchen environments, resulting in a better user experience.
[0033] In some embodiments, such as Figure 2As shown, the top shell 12 is hinged to the lower shell 11 via a connector 120, allowing it to reciprocate relative to the lower shell 11. This design, by enabling the top shell 12 to reciprocate relative to the lower shell 11, allows for easy opening of the mounting cavity 10 simply by flipping the top shell 12, eliminating the need for complex disassembly. This makes the installation and maintenance of internal components (such as the heating element 15) of the top shell 12 more convenient, significantly improving installation efficiency and ease of maintenance. The connector 120 can be a combination of a hinge base and a pivot, a hinge, or a combination of a connecting shaft and a shaft hole, to enable the reciprocating flipping between the top shell 12 and the lower shell 11.
[0034] Specifically, both the lower shell 11 and the top shell 12 have quadrilateral cross-sections along the horizontal direction. This regular shape not only provides a defined boundary for the layout of internal components, facilitating efficient use of space, but also allows the edges of the top shell 12 and the lower shell 11 to be aligned in a plane or stepped manner when closed, resulting in a neat appearance and making the structure on the side where the connector 120 is located more reliable. By placing the connector 120 on either side adjacent to the user's operating side a, the flipping operation of the top cover, relative to the user's operating side a, is performed on the left or right side, and the flipping direction is vertical, without occupying lateral space, thus reducing the space requirements of the cooking machine.
[0035] In some embodiments, such as Figure 1 and Figure 2 As shown, at least on the side of the lower housing 11 that is far from and opposite to the user operation side a, a recess 110 is provided to avoid obstacles. By providing the recess 110, when the cooking machine is placed against the wall, obstacles such as pipes or sockets on the wall can be located in the recess 110 and will not cause interference. This allows the cooking machine to be placed against the wall, which not only improves the overall aesthetics and safety but also increases the space utilization rate.
[0036] In some embodiments, such as Figure 2 and Figure 3 As shown, the multi-head cooking machine 1 also includes a liquid feed assembly 16. The liquid feed assembly 16 is disposed within the receiving space 111 and is supplied via a delivery pipe 160 (see reference). Figure 7The liquid component 16 delivers liquid materials into the pot body 13, and the output end of the liquid delivery pipe 160 extends from the stirring assembly 14 toward the pot body 13. Specifically, during the cooking process, liquid materials such as water, cooking oil, cooking wine, soy sauce, or broth need to be added. Therefore, by setting up this liquid component 16, the required liquid materials can be stored, and the corresponding liquid materials can be delivered to the pot body 13 through the liquid delivery pipe 160 for addition. The liquid component 16 may include a combination of components such as a tank, a delivery pump, and related control valves. The liquid component 16 is placed in the receiving space 111 and is not directly exposed, maintaining the integration and appearance of the whole machine. Furthermore, the liquid component 16 is isolated from the high-temperature environment in the mounting cavity 10 by the receiving space 111, which helps to ensure the quality of the liquid materials. In addition, it can also lower the overall center of gravity of the cooking machine, making it less prone to tipping over and improving the overall safety of use.
[0037] The infusion tube 160 can be made of food-grade materials such as silicone tubing or Teflon flexible tubing to ensure the health and safety of liquid delivery. The output end of the infusion tube 160 extends from the stirring assembly 14 and faces the pot body 13. In this way, the infusion tube 160 is concealed within the internal cavity or pre-reserved channel of the stirring assembly 14, preventing it from being exposed and protecting both the tube and the overall aesthetics. Simultaneously, the output end of the infusion tube 160 facing the pot body 13 allows the delivered liquid to be directly sprayed into the pot body 13, achieving accurate liquid addition. The added liquid is dispersed by the stirring assembly 14 and mixed with the ingredients, achieving rapid and uniform addition of liquid and ingredients.
[0038] In some embodiments, such as Figure 2 and Figure 3As shown, the liquid assembly 16 includes a liquid tank 161 for storing liquid and a transfer pump (not shown) for drawing liquid from the liquid tank 161 and transferring it to the pot body 13. The containing space 111 is divided into a first sub-cavity 1111 and a second sub-cavity 1112 by a partition 112. The liquid tank 161 is located in the first sub-cavity 1111, and the transfer pump is located in the second sub-cavity 1112. Specifically, the liquid tank 161 can be designed as a transparent container or a container with a liquid level observation window for easy monitoring of the remaining liquid level. The top of the liquid tank 161 has a filling port with a sealing cap, and the bottom or lower part has an outlet for easy connection to the transfer pump. The transfer pump can be a peristaltic pump, which does not directly contact the liquid, improving the safety and hygiene of liquid transfer. Of course, provided that the usage requirements are met, the transfer pump can also be set as a gear pump or other types. The accommodating space 111 is divided into two parallel sub-cavities, a first sub-cavity 1111 and a second sub-cavity 1112, by a partition 112. This allows the liquid tank 161 and the transfer pump to be installed separately, ensuring that the liquid tank 161, which poses a risk of leakage, will not affect the safety of the transfer pump. The two do not interfere with each other, achieving the purpose of separating wet and dry materials. The parallel first sub-cavities 1111 and the second sub-cavities 1112 have a consistent height range, thus providing ample installation space and allowing for the placement of components of different heights.
[0039] In some embodiments, such as Figure 2 and Figure 3 As shown, the accommodating space 111 is further divided by a partition 112 into a third sub-cavity 1113, which is located at the back of the lower housing 11 relative to the user operation side a. This third sub-cavity 1113 is used to house the electrical components of the entire cooking machine, such as the main power switch controlling the overall power supply and electrical connectors for data cable access. By separating the components into the third sub-cavity 1113, the internal electrical components can be installed independently and away from the user operation side a, improving overall safety. The height range of the third sub-cavity 1113 is essentially the same as that of the first sub-cavity 1111 and the second sub-cavity 1112, both extending vertically, thus providing ample space to accommodate the installation of multiple parts.
[0040] In some embodiments, such as Figure 1 and Figure 3As shown, the multi-head cooking machine 1 also includes a baffle 17. This baffle 17 is detachably connected to the edge of the lower housing 11 on the side opposite to the user's operating side a. The baffle 17 serves at least to block oil splattering inside the pot 13. Thus, during use, the baffle 17 effectively prevents splattered oil from adhering to the walls or floor of the usage area, concentrating the oil splattered within the area of the top housing 12, significantly improving ease of cleaning. Furthermore, the detachable design of the baffle 17 facilitates disassembly and cleaning, demonstrating clever design.
[0041] In some embodiments, such as Figure 1 As shown, along the direction from the baffle 17 to the user operation side a, the heating positions 150 are arranged side by side and spaced apart, and the interval between two adjacent heating positions 150 is equal. This arrangement of the heating positions 150 in the longitudinal direction ensures that the heating centers are essentially on the same straight line, eliminating the need for multi-directional or multi-angle arrangements, simplifying manufacturing and installation, and facilitating the installation of the heating elements within the mounting cavity 10. Furthermore, utilizing the longitudinal space for overall arrangement reduces the requirement for lateral dimensions, thus reducing the lateral size of the equipment. Moreover, the equal interval between adjacent heating positions 150 minimizes the longitudinal space occupied while ensuring that the pots 13 placed on each heating position 150 do not interfere with each other during operation, facilitating independent cooking.
[0042] In some embodiments, such as Figure 1 As shown, a drain trough 121 is provided on the edge of the top shell 12 near the user's operating side a. Specifically, during use, it is necessary to rinse the dirt on the top shell 12 to ensure overall cleanliness. Therefore, by providing the drain trough 121, wastewater on the top shell 12 can be collected and discharged uniformly, preventing wastewater from flowing around randomly and improving the convenience of cleaning. In one possible implementation, the top shell 12 can be set to tilt towards the drain trough 121, which can improve the effectiveness of wastewater collection in the drain trough 121 and reduce the labor intensity of cleaning.
[0043] In some embodiments, such as Figures 2 to 4As shown, the multi-head cooking machine 1 also includes an air inlet housing 181, an air outlet 182, and a fan 183. The air inlet housing 181 is connected to the top of the lower housing 11 located on the user operation side a, and the bottom of the air inlet housing 181 has an air inlet 1811 for allowing outside air to enter the mounting cavity 10. The air outlet 182 is used to allow air to flow out of the mounting cavity 10, and the air outlet 182 is located on the side of the top housing 12 opposite to the user operation side a. The fan 183 is disposed in the mounting cavity 10, and the fan 183 is used to draw outside air in from the air inlet 1811 and out from the air outlet 182 to at least dissipate heat from the heating element 15. Specifically, the air inlet 1811 is located at the bottom of the air inlet housing 181, allowing air to enter from the bottom. Under the influence of gravity, this helps reduce the possibility of drawing in oil fume particles from the kitchen environment, thus protecting the components inside the mounting cavity 10. Furthermore, the bottom-mounted air inlet 1811 is not directly visible, preserving the overall aesthetics of the user's operating side a. A filter 184 is installed inside the air inlet housing 181 to intercept dust, fibers, and some oil fume particles entering with the air, further enhancing the safety of the components inside the mounting cavity 10. The air outlet 182 is located on the rear side opposite to the user's operating side a, allowing the air flowing in from the air inlet 1811 to traverse the entire longitudinal flow path, ensuring sufficient contact with the heating element 15 for heat absorption. Moreover, the through-flow design improves overall heat dissipation efficiency. The fan 183 is installed inside the cavity to generate forced convection, so that outside air can be drawn into the cavity 10 from the air inlet 1811 and then driven to be discharged through the air outlet 182, so that the air in the cavity 10 can flow smoothly and dissipate heat.
[0044] In one possible implementation, both the air inlet 1811 and the air vent 1811 can be designed as elongated grids or arrayed circular holes, ensuring sufficient ventilation area while preventing large-scale entry of foreign objects. The fan 183 can be an axial fan or a variable-speed fan, which can improve suction power, achieve rapid airflow and heat dissipation, and ensure the temperature safety of the heating element 15 under prolonged high-load operation. The filter element 184 can be a filter cotton or filter paper, or other object that allows air to pass through and has adsorption capacity.
[0045] In some embodiments, such as Figure 1 and Figure 2As shown, a baffle plate 113 is provided on the top surface of the lower housing 11, protruding along the edge that matches and covers the top housing 12. Specifically, by providing the baffle plate 113, the maximum height of the gap formed when the top housing 12 and the lower housing 11 are closed is increased, thereby increasing the difficulty for external water, dust, and other debris to enter through the gap between the top housing 12 and the lower housing 11. This provides protection for electrical components (such as the heating assembly 15, circuit boards, etc.) installed in the mounting cavity 10, improving the overall stability of the cooking machine. Furthermore, the electrical components installed in the mounting cavity 10 are all raised and installed with a certain height from the bottom surface by support columns. Even if water accidentally enters the mounting cavity 10, it can avoid direct contact with the electrical components. At the same time, a drain hole 185 communicating with the mounting cavity 10 can be provided on the lower housing 11 for the drainage of liquid that accidentally enters the mounting cavity 10. In the embodiments of the present invention, as Figure 1 and Figure 2 As shown, since the inner cavity of the air inlet housing 181 is connected to the mounting cavity 10, a drain hole 185 is provided at the bottom of the air inlet housing 181 at a position corresponding to the mounting cavity 10, so that the liquid in the mounting cavity 10 can be discharged in time. By setting the drain hole 185 on the air inlet housing 181, the drain hole 185 can be machined simultaneously when machining the air inlet 1811 of the air inlet housing 181, which improves the convenience of production and also ensures the integrity of the appearance structure of the lower housing 11.
[0046] In some embodiments, such as Figure 1 , Figure 5 and Figure 6 As shown, the stirring assembly 14 includes a mounting base 140, a stirring arm 141, a connector 142, a first stirring blade 143, a second stirring blade 144, a drive component 148, and a transmission assembly 145. The mounting base 140 is fixed to the top shell 12 to provide a mounting foundation. The stirring arm 141 is connected to the mounting base 140 via a rotating shaft 147. The connector 142 is connected to the stirring arm 141. The first stirring blade 143 and the second stirring blade 144 are connected to the bottom of the connector 142. The drive component 148 is mounted on the stirring arm 141. Specifically, the stirring arm 141 serves as the support and movement mechanism for the entire assembly. It is connected to the mounting base 140 via the rotating shaft 147 and can reciprocate relative to the pot body 13 by lifting or lowering, thereby driving the connector 142 and other parts connected to the connector 142 to lift or lower relative to the pot body 13. The stirring arm 141 can be made of high-strength aluminum alloy, stainless steel or plastic and has the strength to meet the support requirements. The internal hollow design of the stirring arm 141 is to facilitate the wiring and installation of the drive unit 148 and some liquid pipelines and other parts.
[0047] The connector 142 is connected to the stirring arm 141 and moves with the stirring arm 141. Specifically, one end of the stirring arm 141 is connected to the rotating shaft 147, and the other end of the stirring arm 141 is used for mounting the connector 142, so that after installation, the connector 142 can reciprocate between lifting and lowering with the stirring arm 141. In one possible embodiment, the connector 142 can be a split design consisting of an upper housing and a lower housing 11 connected by screws or clips. The connector 142 has an internal installation space for accommodating the installation of the transmission component 145, and the detachable connection between the upper housing and the lower housing 11 facilitates the installation and maintenance of the internal transmission component 145. The connector 142 may have an installation structure (such as a connecting column or mounting base 140) to support the installation connection of the transmission component 145 (such as a gear set), so that the transmission component 145 can be reliably installed in the corresponding position, thereby stably realizing the corresponding transmission function. The connector 142 can be made of stainless steel or food-grade engineering plastic to ensure good durability and hygiene safety in high temperature, high humidity and food contact environments.
[0048] like Figure 5 and Figure 6 As shown, both the first stirring blade 143 and the second stirring blade 144 are movably connected to the connector 142, while the driving member 148 is mounted on the stirring arm 141. The driving member 148 drives the connector 142 to rotate, and thus, under the action of the transmission assembly 145, both the first stirring blade 143 and the second stirring blade 144 can rotate relative to the connector 142 to stir the food. Specifically, the transmission assembly 145 is installed inside the connector 142. This transmission assembly 145 is used to transmit the driving force of the driving member 148 to make the first stirring blade 143 and the second stirring blade 144 rotate in opposite directions. The transmission assembly 145 can be a mechanism that can realize motion transmission, such as a gear combination or a pulley combination. The first stirring blade 143 is at least used to push and disperse the food located at the center of the pot body 13 outwards, while the second stirring blade 144 is at least used to gather the dispersed food back to the center of the pot body 13. In this way, under the driving force provided by the driving component 148, the connector 142, the first stirring blade 143 and the second stirring blade 144 can all rotate. Thus, through the coordinated stirring of the first stirring blade 143 and the second stirring blade 144, the ingredients in the pot 13 can be repeatedly stirred between being dispersed and gathered. This allows the ingredients to be fully stirred, improves the uniformity of stirring, and greatly enhances the stirring effect.
[0049] In some embodiments, such as Figure 6As shown, the central axis of the first stirring blade 143 is vertically arranged, so that it mainly generates horizontal stirring force when rotating, dispersing the food located at the bottom of the pot 13 radially. Specifically, the side of the first stirring blade 143 that contacts the inside of the pot 13 can be set according to the shape of the bottom of the pot 13, so as to maintain good adhesion to the bottom of the pot 13, thereby dispersing and breaking up the food gathered in the center of the pot 13 radially outward, preventing the food from piling up.
[0050] In some embodiments, such as Figure 6 As shown, the central axis of the second stirring blade 144 is inclined relative to the vertical direction. Therefore, during rotation, its motion can be decomposed into horizontal and axial (vertical) component motions, forming a motion path for stirring the food from the periphery of the pot 13 towards the center and from the bottom upwards. Specifically, the horizontal component motion gathers the food from the edges of the pot 13 towards the center, opposite to the function of the first stirring blade 143. The axial component motion generates a slight upward lifting force, causing the food at the bottom of the pot to tumble upwards. Ultimately, this effectively gathers the scattered food back to the central area, preventing food accumulation on the pot wall and significantly improving the thoroughness of stirring.
[0051] In some embodiments, such as Figure 5 and Figure 6 As shown, the first stirring blade 143 and the second stirring blade 144 are spaced apart at both ends of the bottom of the connector 142. The gap between them provides space for their rotation, preventing movement interference during stirring. Furthermore, the stirring areas achievable by each of the first stirring blade 143 and the second stirring blade 144 have at least a non-overlapping area in their vertical projections. Thus, the combined stirring of the first stirring blade 143 and the second stirring blade 144 creates a larger stirring area, increasing the likelihood of the food being stirred and thereby improving the stirring effect.
[0052] Specifically, the first stirring blade 143 and the second stirring blade 144 can both be configured as a combination of a blade shaft and a scraper. One end of the blade shaft is connected to the connector 142 via a bearing, and the scraper is connected to the other end of the blade shaft. After the stirring arm 141 descends, the scraper adheres to the inner wall of the pot body 13, thereby stirring the food inside the pot body 13. The installation position of the blade shaft and the connector 142 can be locked by means of a snap ring or a pin to ensure the stability of the position after installation.
[0053] Specifically, "the stirring arm 141 reciprocating between lifting and lowering relative to the pot body 13" means that the stirring arm 141 can repeatedly lift away from or lower towards the pot body 13 as needed. For example, when the stirring arm 141 is lifted relative to the pot body 13, it moves away from the pot body 13, thus avoiding interference when adding ingredients to the pot body 13, pouring cooked food out of the pot body 13, or cleaning. Conversely, when the stirring arm 141 is lowered relative to the pot body 13, it moves closer to the pot body 13, allowing the parts within the stirring arm 141 used for stirring (such as the stirring blade) to maintain an elastic fit against the inner wall of the pot body 13, enabling the stirring of the food within the pot body 13. Thus, the stirring arm 141 reciprocates between lifting and lowering as needed for cooking the dish. The power to drive the stirring arm 141 to reciprocate between lifting and lowering can be achieved by setting a corresponding drive motor or electric push rod in the top shell 12, and is not limited here.
[0054] In some embodiments, such as Figure 6 As shown, the tilt angle α of the central axis of the second stirring blade 144 relative to the vertical direction is within 20°-30°. Specifically, the tilt angle α can be any one of 20°, 22°, 23°, 25°, 27°, 28°, or 30°, or any other value within the 20°-30° range. By setting the tilt angle α of the second stirring blade 144 within the 20°-30° range, according to the principle of force decomposition, the second stirring blade 144 can generate a moderately sized stirring component force that continuously moves towards the center of the pot body 13 when rotating, thereby efficiently gathering the food at the edge of the pot body 13 to the central area. If the tilt angle is too small, the centripetal thrust is insufficient, resulting in low gathering efficiency; if the tilt angle is too large, although the centripetal force is enhanced, the tangential turning ability of the stirring blade on the food is reduced, and the motion resistance may increase. Therefore, by setting the tilt angle of the second stirring blade 144 within the aforementioned range, the second stirring blade 144 can both quickly and powerfully push the ingredients towards the center and maintain sufficient lateral stirring action, ensuring that the ingredients are mixed even during centripetal movement. Of course, in some possible embodiments, the second stirring blade 144 can also be configured with an adjustable tilt angle to meet the needs of different stirring methods or the needs of using pots 13 of different sizes.
[0055] In some embodiments, such as Figure 5 and Figure 6As shown, the stirring assembly 14 also includes a third stirring blade 146. The third stirring blade 146 is connected to the side wall of the connector 142, and the third stirring blade 146 can move with the connector 142 to scrape the food located on the side wall of the pot body 13 back into the pot body 13. Specifically, the third stirring blade 146 can be fixedly connected to the side wall of the connector 142 by plugging, snapping, or threading, or it can be connected by an intermediate component. The scraping part on the third stirring blade 146 for adhering to the side wall of the pot body 13 can be shaped according to the shape of the side wall of the pot body 13, such as setting the edge contour shape to be arc-shaped, so as to have better wall adhesion and effectively scrape off the food adhering to the side wall of the pot body 13, avoiding local burning or waste of food.
[0056] Specifically, the third stirring blade 146 revolves around the central axis of the pot body 13 following the connector 142. During rotation, the scraping part continuously scrapes the food on the side wall of the pot body 13 back into the pot body 13, where it can continue to be scraped and stirred by the first stirring blade 143 and / or the second stirring blade 144. By setting the third stirring blade 146, it can complement the "outward dispersion" of the first stirring blade 143 and the "inward gathering" of the second stirring blade 144. For example, food scraped off the side wall by the third stirring blade 146 falls to the outer perimeter of the bottom of the pot, is then gathered and pushed towards the center by the second stirring blade 144, and then dispersed by the first stirring blade 143. Some food may splash or slide back to the side wall and then be scraped back by the third stirring blade 146. In this way, through the coordinated stirring of the three stirring blades, comprehensive stirring of the bottom center, perimeter, and side walls of the pot body 13 is achieved, ensuring that all the food in the pot body 13 is thoroughly stirred, resulting in excellent stirring effect.
[0057] In some embodiments, such as Figure 7 and Figure 8As shown, the rotating shaft 147 has a channel 1471 inside and a notch 1472 communicating with the channel 1471 on its side wall. The output end of the infusion pipe 160 passes through the channel 1471 and the notch 1472 and is connected to the stirring arm 141. Specifically, the infusion pipe 160 is used to deliver liquid to the ingredients in the pot 13. The inlet end of the infusion pipe 160 is connected to a delivery pump, and the output end of the infusion pipe 160 is used to output the liquid drawn into the pipe into the pot 13. By using a channel 1471 inside the rotating shaft 147 and a notch 1472 communicating with the channel 1471 on its side wall, the output end of the infusion pipe 160 can pass through the channel 1471 and the notch 1472 and be connected to the stirring arm 141, so that the output end of the infusion pipe 160 can always stably face the pot 13 after the stirring arm 141 descends. This design provides a safe and reliable transmission path for the infusion tube 160 inside the rotating shaft 147. It satisfies the requirement for the infusion tube 160 to pass through the inside of the rotating shaft 147, while also ensuring effective protection of the rotating shaft 147 structure for the infusion. During the rotation of the rotating shaft 147, the infusion tube 160 remains in a relatively fixed position, avoiding fatigue damage caused by repeated bending and preventing it from getting stuck in the rotational gaps of the rotating shaft 147 and being damaged. This internal tubing method significantly improves the reliability of liquid delivery via the infusion tube 160.

Any modifications, equivalent substitutions, and improvements made within the spirit and scope of the present invention are included within the scope of protection of the present invention.
