[0003] The cooking machine is equipped with a stirring device that stirs the ingredients in the pot during the cooking process. The stirring device can be lowered relative to the pot to stir the ingredients, or raised away from the pot for easy pouring.

[0014] In some embodiments, the balancing element is a spring, one end of which is connected to the connecting element, and the other end of which is connected to the support body supporting the stirring head; or, the balancing element is a counterweight, which is connected to the connecting element via a connecting rope.

[0015] In some embodiments, the stirring head includes: a body rotatably connected to the frame via the connecting shaft; a stirring blade for stirring food ingredients, the stirring blade being mounted movably on the body; and a stirring motor mounted on the body and connected to the stirring blade, the stirring motor driving the stirring blade to rotate; wherein, when the connecting member is in the first position, the stirring blade is separated from the pot body; and when the connecting member is in the second position, the stirring blade is at least partially located inside the pot body to stir the food ingredients inside the pot body.

[0025] Unless otherwise defined, all technical and scientific terms used in the embodiments of this application have the same meaning as commonly understood by one of ordinary skill in the art. The terminology used in the embodiments of this application is for the purpose of describing the embodiments of this application only and is not intended to limit this application.

[0026] like Figure 1 and Figure 2 As shown in the illustration, this application provides a stirring device 1 for stirring ingredients within the pot 22 of a cooking machine 2. The cooking machine 2 is a device capable of cooking food. During the cooking process, the ingredients contained in the pot 22 need to be stirred to ensure even heating and proper mixing of added seasonings. Therefore, the provided stirring device 1 stirs the ingredients within the pot 22 to meet the requirement of automatic stirring, thereby enabling the cooking machine 2 to reliably cook food.

[0027] Specifically, such as Figure 1 and Figure 3 As shown, the stirring device 1 includes a stirring head 11, a driving component 12, a connecting component 13, and a balancing component 14. The stirring head 11 is movably mounted on the frame 21 of the cooking machine 2 (see reference). Figure 2 The stirring head 11 can be raised or lowered relative to the pot body 22, and the driving member 12 can generate a driving force and transmit the driving force to the stirring head 11 so as to drive the stirring head 11 to reciprocate between raising and lowering. The stirring head 11 has a structure for rotating and stirring the food (such as a stirring blade). Therefore, when the stirring head 11 is lowered to the position, it can stir the food in the pot body 22, and when the stirring head 11 is raised to the position, it can move away from the pot body 22 so as not to interfere with the pouring out of the food in the pot body 22.

[0028] The drive component 12 is a motor or air pump capable of circumferential rotation or repeated rotation within a certain range, thereby generating driving force during rotation. The drive component 12 is connected to the frame 21, which provides a fixed mounting position for the drive component 12. The drive component 12 can be fixed to the frame 21 using screws, snap-fit ​​fasteners, or a mounting plate; various mounting methods are available. The drive component 12 can be directly connected to the stirring head 11, such as by directly connecting the drive shaft of the drive component 12 to the stirring head 11. Alternatively, the drive component 12 can be indirectly connected to the stirring head 11, such as by connecting the drive shaft of the drive component 12 to the stirring head 11 via a transmission shaft or chain, which can reliably drive the stirring head 11 to reciprocate during lifting and lowering.

[0029] Specifically, the connecting member 13 is connected to the drive shaft of the drive member 12 and / or the connecting shaft 110 of the stirring head 11, and moves accordingly. That is, the connecting member 13 can be connected to the drive shaft of the drive member 12, or it can be connected to the connecting shaft 110 of the stirring head 11, or, when the drive shaft of the drive member 12 and the connecting shaft 110 of the stirring head 11 are directly connected, the connecting member 13 can be connected to both the drive shaft of the drive member 12 and the connecting shaft 110 of the stirring head 11. In this way, when the drive member 12 drives the stirring head 11 to rise or fall, the connecting member 13 can move synchronously. Specifically, as shown in the example... Figure 6 and Figure 7 As shown, after the stirring head 11 is raised, the connecting member 13 has a first position; after the stirring head 11 is lowered, the connecting member 13 has a second position. The balancing member 14 is connected to the connecting member 13. The balancing member 14 is used to provide auxiliary force to the stirring head 11 during the lifting or lowering movement. Thus, during the lifting or lowering movement of the stirring head 11, the balancing member 14 moves synchronously with the connecting member 13, thereby generating an auxiliary force that can act on the stirring head 11, so that the stirring head 11 can be lowered or raised smoothly.

[0030] The "first position" and "second position" mentioned above refer to the positional change of the connection point A between the balancer and the connector relative to the axis of the connecting shaft 110 of the stirring head, and are two different positions. Specifically, as shown... Figure 6 As shown, taking the horizontal line L where the axis is located as the position reference, the position when the connection point A is above the horizontal line L is the second position, at which point the stirring head is in a descending state. Figure 7 As shown, the position where connection point A is below the horizontal line L is the first position, at which point the stirring head is in a raised state. Of course, it's understandable that when different positions are chosen as references, the positions of the "first position" and "second position" relative to that reference will change accordingly, but the first position and the second position are still two different positions. The above explanation is for ease of understanding the specific differences between the "first position" and the "second position," and is not intended to be the sole limitation on the interpretation of the first and second positions.

[0031] Specifically, the balancing member 14 generates auxiliary force in the following way: when the connecting member 13 moves from the first position to the second position, the balancing member 14 generates an auxiliary force that prevents the stirring head 11 from descending; and when the connecting member 13 moves from the second position to the first position, the balancing member 14 generates an auxiliary force that pulls the stirring head 11 upward. After the stirring head 11 is raised, the connecting member 13 is in the first position; after the stirring head 11 is lowered, the connecting member 13 is in the second position. That is, when the stirring head 11 moves upward or downward, the connecting member 13 also moves synchronously. Since the balancing member 14 is connected to the connecting member 13, when the position of the connecting member 13 changes, the balancing member 14 is also subjected to force and moves synchronously, thereby generating a corresponding auxiliary force.

[0032] Specifically, the balancing component 14 can be a spring or elastic element, a hydraulic cylinder or a pneumatic cylinder, or a combination of cable and counterweight. Thus, when the connecting component 13 moves from the first position to the second position, it drives the balancing component 14 to move. During this movement, the balancing component 14 requires a force (e.g., if the balancing component 14 is a spring, a corresponding force is required when the spring is stretched). This is equivalent to the balancing component 14 pulling the stirring head 11 in the opposite direction to its descent, thereby hindering the descent of the stirring head 11, reducing its descent speed, and effectively preventing collisions or impacts caused by rapid descent. This allows the stirring head 11 to descend smoothly to the set position. Compared to directly reducing the descent speed of the stirring head 11 by reversing the drive component 12, the reverse pulling of the balancing component 14 is simpler and more practical. It reduces the structural requirements of the drive component 12, eliminates the need for a deceleration structure, and contributes to the overall simplification of the stirring device 1.

[0033] When the connecting member 13 moves from the second position to the first position, the balancing member 14 is in a reset state (like a stretched spring with a tendency to shorten and reset). Therefore, the balancing member 14 generates tension during the reset process. This tension, acting on the connecting member 13, pulls the stirring head 11 upwards, assisting the drive member 12 in lifting the stirring head 11. This reduces the requirement for the drive force output by the drive member 12. Compared to directly driving the stirring head 11 to lift via the drive member 12, providing auxiliary tension through the balancing member 14 makes it easier for the drive member 12 to lift the stirring head 11. In other words, the tension generated during the reset process of the balancing member 14 assists in lifting the stirring head 11, making it easier to lift and improving the convenience of the drive member 12 in lifting the stirring head 11. Moreover, compared to increasing driving force by changing the structure of the driving component 12, the balance component 14 has a simple structure and low manufacturing cost. This method of providing assistance by setting the balance component 14 can not only meet the usage requirements but also help reduce the manufacturing cost of the entire stirring device 1.

[0034] The stirring device 1 provided in this embodiment includes a stirring head 11, a driving member 12, a connecting member 13, and a balancing member 14. The stirring head 11 is movably mounted on the frame 21 of the cooking machine 2. The driving member 12 drives the stirring head 11 to rise or fall relative to the pot body 22. The connecting member 13 is connected to the driving shaft of the driving member 12 and / or the connecting shaft 110 of the stirring head 11 and moves with it. The balancing member 14 is connected to the connecting member 13 and can move with it. With this configuration, the stirring head 11 can be driven to rise or fall under the combined action of the driving member 12, the connecting member 13, and the balancing member 14. This combination of the driving member 12, the connecting member 13, and the balancing member 14 provides driving force. The overall structure is simple and easy to assemble. Moreover, the balancing member 14 can generate an auxiliary force to prevent the stirring head 11 from falling when it falls, so that the stirring head 11 can fall smoothly. When the stirring head 11 is raised, the balancing member 14 generates an auxiliary force to pull the stirring head 11 up, assisting in the smooth raising of the stirring head 11. Thus, the combination of the balancing member 14 and the driving member 12 allows the relatively small driving member 12 to generate a large driving force, reliably driving the lifting and lowering movement of the stirring head 11, and reducing the performance requirements of the driving member 12. The driving member 12 and the balancing member 14 themselves have low manufacturing costs, which also contributes to reducing the overall manufacturing cost of the stirring device 1.

[0035] In some embodiments, such as Figure 1 and Figure 3 As shown, the stirring device 1 also includes a damper 15, which is connected to the connecting shaft 110 of the stirring head 11 and / or the drive shaft of the drive member 12. Specifically, the damper 15 is a rotary damper, which can generate motion resistance, consume rotational motion energy to achieve a buffering effect, and allow the installed object to move smoothly. By connecting the damper 15 to the stirring head 11 and / or the drive member 12, the damper 15 can resist the rotation of the stirring head 11 when the drive member 12 drives the stirring head 11 to rotate, thereby slowing down the rotation speed of the stirring head 11 and allowing the stirring head 11 to rotate at a preset speed. Understandably, the specific principle by which the damper 15 generates motion resistance is the same as that of similar dampers in the prior art, and will not be elaborated here.

[0036] Because the stirring head 11 is relatively heavy, it experiences significant inertial force during lifting or lowering. Therefore, by incorporating a damper 15, the inertial force of the stirring head 11 during movement can be balanced, preventing excessively rapid movement and impact that could damage the drive component 12 or other parts. Under the action of the damper 15, the stirring head 11 can rotate at a basically uniform speed during both lifting and lowering movements, effectively ensuring the smoothness and reliability of its movement.

[0037] In some embodiments, the drive shaft of the drive component 12 is directly connected to the connecting shaft 110 of the stirring head 11. Specifically, the drive shaft of the drive component 12 and the connecting shaft 110 of the stirring head 11 can be directly connected by bolts or welding, or they can be connected by a coupling. This transmission method, which directly connects the drive shaft of the drive component 12 to the connecting shaft 110 of the stirring head 11, allows the driving force generated by the drive component 12 to act directly on the stirring head 11 without being transmitted through other parts, resulting in less driving force transmission loss and better driving reliability.

[0038] In some embodiments, such as Figure 1 and Figure 3 As shown, the stirring device 1 also includes a transmission mechanism 16. This transmission mechanism 16 transmits the driving force of the driving member 12 to the stirring head 11. The transmission mechanism 16 is connected between the drive shaft of the driving member 12 and the connecting member 13. This arrangement allows for indirect transmission between the driving member 12 and the stirring head 11 via the transmission mechanism 16, which can be a connecting rod assembly, gear set, or belt, etc. By indirectly driving the stirring head 11 to rotate through the transmission mechanism 16, advantages such as buffering and vibration reduction, and overload protection are provided. Furthermore, the driving member 12 and the stirring head 11 do not need to be directly connected and can be separately arranged, making the overall structural layout more flexible, facilitating the reduction of overall structural size, and simplifying transmission speed adjustment. When the transmission mechanism 16 is used, the connecting member 13 can be installed on the connecting shaft 110 of the stirring head 11, while the driving member 12 can be fixed by a mounting plate or fixed to a support member for mounting the pot body 22. The transmission mechanism 16 then enables transmission between the driving member 12 and the connecting member 13. In this way, the connecting piece 13 can be driven by the transmission mechanism 16 to follow the drive shaft of the drive piece 12, thereby driving the stirring head 11 to rise or fall.

[0039] In some embodiments, such as Figure 1 and Figure 3As shown, the transmission mechanism 16 includes a first transmission rod 161. The first end of the first transmission rod 161 is connected to the drive shaft of the drive member 12, and the second end of the first transmission rod 161 is movably connected to the connecting member 13. Specifically, the first transmission rod 161 can be configured as a straight rod or a curved rod according to transmission requirements, and has a first end and a second end for connection. The first end of the first transmission rod 161 is connected to the drive shaft of the drive member 12, and the connection method can be a fixed connection or a movable connection, as long as it is ensured that the first transmission rod 161 can be driven to rotate when the drive member 12 rotates. Of course, a fixed connection between the first end of the first transmission rod 161 and the drive shaft of the drive member 12 can better ensure the reliability of the transmission. The second end of the first transmission rod 161 is movably connected to the connecting member 13, allowing relative rotation between the two to adjust the transmission angle. In this way, at least one end of the first and second ends of the first transmission rod 161 is movably connected to the corresponding connected object, enabling adaptive adjustment of the transmission angle. Therefore, when the transmission between the drive member 12 and the connecting member 13 is realized through the first transmission rod 161, a smooth and stable transmission effect can be achieved, so that the stirring head 11 can be raised or lowered smoothly. In some embodiments, such as Figure 1 and Figure 3 As shown, the transmission mechanism 16 also includes a second transmission rod 162. The first end of the second transmission rod 162 is movably connected to the second end of the first transmission rod 161, and the second end of the second transmission rod 162 is movably connected to the connecting member 13. Specifically, when the transmission mechanism 16 is provided with a second transmission rod 162, the second transmission rod 162 can be configured as a straight rod or a curved rod, etc., depending on the installation position requirements. The first and second ends of the second transmission rod 162 are movably connected to the objects to be connected. In this way, by providing the second transmission rod 162, it is easier to adjust the relative installation position of the driving member 12 and the stirring head 11, ensuring reliable transmission while also contributing to the compact arrangement of the overall structure. Moreover, by configuring both ends of the second transmission rod 162 as movably connected, the need for adjusting the transmission angle can be met, effectively avoiding jamming during transmission and thus ensuring smooth transmission.

[0040] In some embodiments, such as Figure 4 and Figure 5 As shown, the stirring device 1 also includes a buffer 18 and a stop post 19. The buffer 18 is connected to the first transmission rod 161 or the second transmission rod 162, thereby moving with the first transmission rod 161 or the second transmission rod 162. The stop post 19 is fixed to the frame 21 (see reference). Figure 2The position of the stop post 19 remains unchanged. The stop post 19 is located in front of the first transmission rod 161 or the second transmission rod 162 when it moves to lower the stirring head 11. Therefore, when the buffer 18 moves and collides with the stop post 19, it can prevent the first transmission rod 161 or the second transmission rod 162 from continuing to move, thus limiting the downward position of the stirring head 11. In this way, by reasonably setting the position of the stop post 19, the downward position of the stirring head 11 can be limited by the mutual abutment of the buffer 18 and the stop post 19, ensuring that the lowered stirring head 11 is positioned in a suitable location within the pot body 22, thereby achieving effective stirring of the food in the pot body 22.

[0041] Specifically, the buffer 18 absorbs energy and reduces impact force through springs, damping, or hydraulic pressure. By mounting the buffer 18 on the first transmission rod 161 or the second transmission rod 162, compared to mounting the buffer 18 on the frame or other locations requiring specific pre-reserved installation space, this arrangement makes reasonable use of the available space on the first transmission rod 161 or the second transmission rod 162, eliminating the need for additional clearance design and improving the overall structural compactness. Simultaneously, the buffer 18 actively limits its movement by following the first transmission rod 161 or the second transmission rod 162, achieving high limiting accuracy and more effectively absorbing impact energy, resulting in a good buffering effect.

[0042] Specifically, when the stirring device 1 is equipped with a buffer 18, the damper 15 can be selected according to the actual design needs, which provides good flexibility.

[0043] In some embodiments, such as Figure 4 and Figure 5 As shown, a sleeve 191 is also provided on the stop post 19. The sleeve 191 is movably fitted on the stop post 19 and can rotate around the stop post 19. With this arrangement, when the buffer 18 comes into contact with the sleeve 191, the sleeve 191 rotates under force, so that the buffer 18 is not subjected to lateral force, thereby protecting the buffer 18, effectively preventing damage to the buffer 18, and improving the service life of the buffer 18.

[0044] In some embodiments, such as Figure 1 and Figure 3As shown, the stirring device 1 also includes a mounting base 17, which is connected to the frame 21. Specifically, the mounting base 17 can be formed by bending sheet metal, possessing a certain structural strength. Fixing the mounting base 17 to the frame 21 and combining it with the frame 21 as a whole not only enhances the structural strength of the frame 21 but also creates a mounting position for installing other parts. A limiting structure 171 is provided on the mounting base 17 to limit the lifting height of the stirring head 11. In specific application scenarios, the drive component 12 rotates to drive the stirring head 11 to lift. The lifting height of the stirring head 11 has a maximum limit to ensure that the rotation range of the stirring head 11 meets the usage requirements and avoids excessive rotation that could damage the equipment. Therefore, by providing a limiting structure 171 on the mounting base 17, which can cooperate with the drive shaft of the drive component 12, the lifting height of the stirring head 11 is limited by limiting the maximum rotation range of the drive component 12. The limiting structure 171 can also cooperate with the first transmission rod 161. By limiting the maximum range of motion of the first transmission rod 161 when lifting the stirring head 11, the maximum lifting height of the stirring head 11 can also be limited. In this way, the maximum lifting height of the stirring head 11 can be limited by the limiting structure 171, which better ensures the reliability of the stirring device 1's function.

[0045] Specifically, the limiting structure 171 can be a limiting block that restricts the drive shaft of the drive member 12 or the first transmission rod 161 from continuing to drive the stirring head 11 to rise, achieving blocking and limiting through mutual abutment; it can also be a pull chain, which can limit the maximum lifting height of the stirring head 11 by setting the maximum length of the pull chain; or it can be a collision switch, which generates a signal to control and shut off the drive member 12 from continuing to rotate through collision, thus also limiting the maximum lifting height of the stirring head 11. Of course, other structures that can achieve limiting can also be used, and the specific setting method can be selected according to the design requirements.

[0046] In one possible implementation, a limiting notch is provided on the mounting base 17 as a limiting structure 171. When the first transmission rod 161 drives the connecting member 13 to move from the second position to the first position, and the first transmission rod 161 moves into the limiting notch and collides with it, the movement of the first transmission rod 161 is restricted, thereby preventing the stirring head 11 from being raised further. This achieves the limitation on the maximum height that the stirring head 11 can be raised, thus protecting the accuracy of the movement position of the stirring head 11.

[0047] In some embodiments, such as Figure 4 and Figure 5As shown, when the drive component 12 is mounted and fixed using a mounting base 17, the stop post 19 can be fixedly mounted on the mounting base 17. Thus, the stop post 19 can be set simultaneously when the mounting base 17 is manufactured, which improves the convenience of production and manufacturing.

[0048] Reference Figure 3 In one embodiment, since a damper 15 is connected to the drive shaft of the drive member 12 to balance the rotational speed of the drive member 12, the mounting base 17 is bent to form a stepped position. After the mounting base 17 is fixedly connected to the frame 21, an installation space is formed between the mounting position and the frame 21. The damper 15 is hidden in this installation space and can be fixedly installed on the frame 21 to form a damping effect. The drive member 12 is located on the other side of the mounting base 17 relative to the damper 15, so that the damper 15 and the drive member 12 are located on opposite sides of the mounting base 17. In this way, the design of the mounting base 17 satisfies the installation of the drive member 12, and also allows the damper 15 to be installed in a hidden manner. The overall installation structure is simple and the design is ingenious.

[0049] In some embodiments, such as Figure 1 and Figure 3 As shown, a connecting hole 131 is provided at one end of the connector 13, and a fixing post 132 is provided at the opposite end of the connector 13. The drive shaft of the drive component 12 and / or the connecting shaft 110 of the stirring head 11 are engaged in the connecting hole 131, while the balancing component 14 is connected to the fixing post 132. In this way, the drive shaft of the drive component 12 and / or the connecting shaft 110 of the stirring head 11 are engaged in the connecting hole 131, which realizes the fixed installation of the connector 13, so that the connector 13 can rotate synchronously with the drive shaft of the drive component 12 or the connecting shaft 110 of the stirring head 11. The fixing post 132 facilitates the installation and connection of the balancing component 14, so that auxiliary force can be applied to the connector 13. Of course, the balancing component 14 can also be connected by providing holes or connecting buckles on the connector 13, and there are various connection methods.

[0050] Specifically, the connection method between the connecting hole 131 on the connector 13 and the drive shaft of the drive component 12 or the connecting shaft 110 of the stirring head 11 can be an interference fit, a direct fixing connection using screws or similar fasteners, or the connecting hole 131 can be a slotted hole. After inserting the drive shaft of the drive component 12 and / or the connecting shaft 110 of the stirring head 11 into the connecting hole 131, the diameter of the slotted hole can be reduced using screws or similar fasteners, thus clamping and fixing the object inserted into the hole. The fixing connection methods between the drive shaft of the drive component 12 and / or the connecting shaft 110 of the stirring head 11 and the connector 13 are diverse and can be flexibly selected.

[0051] In some embodiments, the balancing element 14 is a spring, with one end connected to the connecting element 13 and the other end connected to the support body supporting the stirring head 11. Specifically, the spring is in a contracted state under normal conditions, so when the spring is stretched, a force needs to be applied to it. The stretched spring always has a restoring force that can contract, thus generating a pulling force on the connected object. In this way, setting the balancing element 14 as a spring not only reduces material costs but also allows for the selection of appropriate spring models according to the required auxiliary force, providing good flexibility. By setting the balancing element 14 as a spring, one end of the spring can be connected to the support body supporting the stirring head 11, and the other end can be connected to the fixing post 132 provided on the connecting element 13. Thus, when the stirring head 11 descends, it pulls the spring to lengthen, allowing the spring to dissipate the gravity present during the descent of the stirring head 11, hindering the rapid descent of the stirring head 11, thereby achieving a smooth descent of the stirring head 11. When the stirring head 11 is in the descending state, the spring is constantly stretched. When the stirring head 11 is raised, the spring gradually contracts and returns to its original position. At this time, the spring can apply a pulling force to the stirring head 11, assisting in the lifting of the stirring head 11, thereby reducing the requirement for the driving force provided by the drive component 12. By combining the drive component 12 and the spring, it is possible to lift the heavy stirring head 11, which has a simple structure and low manufacturing cost.

[0052] In some embodiments, the balancing element 14 can also be configured as a counterweight, which is connected to the connecting element 13 via a connecting rope. Specifically, one end of the connecting rope is connected to the fixing post 132 of the connecting element 13, and the other end of the connecting element 13 is connected to the counterweight. When the stirring head 11 descends, the counterweight needs to be pulled upwards. At this time, the descent speed of the stirring head 11 can be reduced by the rise of the counterweight, so that the stirring head 11 can descend smoothly. When it is necessary to raise the stirring head 11, the downward movement of the counterweight generates an upward pulling force on the stirring head 11, which can assist in raising the stirring head 11, thereby reducing the requirement for the driving force provided by the driving element 12. This combination of counterweight and driving element 12, using the rise or fall of the counterweight to provide auxiliary force, can also reliably realize the raising or lowering movement of the stirring head 11. Furthermore, the magnitude of the auxiliary force can be adjusted by changing the weight of the counterweight according to application requirements, providing good flexibility.

[0053] In some embodiments, such as Figure 1As shown, the stirring head 11 includes a body 111, a stirring blade 112, and a stirring motor (not shown in the figure). The body 111 is the main component of the stirring head 11, providing a mounting position for the stirring blade 112 and the stirring motor. The body 111 is rotatably connected to the frame 21 via a connecting shaft 110, allowing the body 111 to move relative to the frame 21 under the action of the driving component 12, thereby achieving lifting or lowering. The stirring blade 112 is used to stir the food. The stirring blade 112 is mounted movably on the body 111, and the stirring motor is mounted on the body 111 and connected to the stirring blade 112, driving the stirring blade 112 to rotate. This configuration allows the stirring blade 112 to rotate under the drive of the stirring motor, thereby achieving stirring of the food in the pot 22.

[0054] Specifically, such as Figure 3 and Figure 6 As shown, when the connector 13 is in the first position, the stirring blade 112 is separated from the pot body 22, so that the stirring blade 112 does not interfere with the movement of the pot body 22 (such as when the pot body 22 needs to be rotated or tilted to facilitate the pouring out of the food). When the connector 13 is in the second position, the stirring blade 112 is at least partially located inside the pot body 22 to stir the food inside the pot body 22. At this time, the stirring blade 112 can maintain contact with the bottom of the pot body 22 and can slide relative to it, thereby realizing the stirring of the food inside the pot body 22. The stirring blade 112 can be made of food-grade stainless steel, which has good structural strength and is safe and hygienic.

[0055] like Figure 2 As shown in the illustration, this application also provides a cooking machine 2, including a frame 21, a pot body 22, and a stirring device 1 as described in any of the above embodiments. The frame 21 is the main supporting component of the entire cooking machine 2, and other parts of the cooking machine 2 are directly or indirectly mounted on the frame 21. The pot body 22 is used to hold food ingredients. The pot body 22 is connected to the frame 21 and can be fixedly connected to the frame 21 or can rotate at a certain angle relative to the frame 21, so that the opening of the pot body 22 is tilted downwards to facilitate the pouring out of the food ingredients. The stirring device 1 is used to stir the food ingredients in the pot body 22. The stirring head 11 is movably mounted on the frame 21 and reciprocates between lifting and lowering relative to the pot body 22. Other parts of the stirring device 1 are arranged inside or outside the frame 21 according to the installation requirements, so as to realize the driving of the stirring head 11 to lift or lower relative to the frame 21. The cooking machine 2 provided in this embodiment of the application adopts the stirring device 1 described in any of the above embodiments. Therefore, the cooking machine 2 also has the advantages of the stirring device 1, which will not be elaborated here. The cooking machine 2 can reliably realize the automatic stirring of ingredients in the pot 22, eliminating the need for manual stirring of ingredients, improving the convenience of cooking ingredients and providing a good user experience.
