[0038] The working principle of the cooking and stirring device of the present application is as follows:

[0039] like Figure 2The cooking and stirring device is shown in the figure when cooking and stirring are not in progress. At this time, the first folding arm 3 and the second folding arm 4 are in a folded and retracted state, and the first folding arm 3 and the second folding arm 4 form a vertical parallel state with each other, and the entire stirring device completely avoids the top of the cooking container 5, so that when cooking is not in progress, the utilization of space can be improved; when cooking is required, the first folding arm 3 is driven by the rotating driving end of the rotating driving assembly 2 to rotate counterclockwise, and rotated until the first folding arm 3 and the mounting plate 1 form a vertical state, so that the second folding arm 4 extends into the cooking container 5 under the driving effect of gravity, and at this time the second folding arm 4 and the first folding arm 3 also form a vertical state, and the stirring state is unfolded as shown in FIG. Figure 1 As shown, the stirring rod 41 is driven by the first rotary drive member 6 to stir the food in the cooking container 5; after the cooking is completed, the first folding arm 3 is rotated clockwise by the rotary drive end of the rotary drive assembly 2 to fold and retract, and the second folding arm 4 is driven to fold and retract under the action of gravity until the food is retracted as shown in FIG. Figure 2 Status shown.

[0040] like Figure 3 The stirring mechanism in the prior art includes a stirring member 100, a lid 200 and a container 300. The stirring mechanism causes hot steam to condense on the lid 200 to form condensed water to flow back or drip into the cooking container. The cooking stirring device in the utility model is provided with two foldable folding arms. When the food in the cooking container needs to be stirred, the first folding arm 3 can be rotated counterclockwise by the rotating driving component 2, and the second folding arm 4 is extended into the cooking container for stirring. When stirring is not needed, the first folding arm 3 is rotated clockwise by the rotating driving component 2 to be folded and retracted, and the second folding arm 4 is driven to fold with it under the action of gravity, so as to conveniently realize the stirring of the food in the cooking container, and overcome the defect of the existing cooking stirring mechanism that hot steam condenses on the lid 200 to form condensed water to flow back or drip into the cooking container, causing hygienic problems. At the same time, through the ingenious structural design, the two folding arms are folded and retracted at the same time by using a rotating power source, which saves costs and improves the space utilization rate of the cooking process.

[0041] Example 2

[0042] See also Figure 4 The cooking and stirring device also includes a connecting flexible shaft 7; the first rotating driving member 6 is installed on the inner end surface of the mounting plate 1; the output shaft of the first rotating driving member 6 is connected to the rotating shaft of the stirring rod 41 through the connecting flexible shaft 7.

[0043] Specifically, the cooking and stirring device also includes a flexible shaft pressure plate 8; an opening groove 31 is provided at one end where the first folding arm 3 and the second folding arm 4 are connected, and the flexible shaft pressure plate 8 is connected above the opening groove 31 to form a channel between the opening groove 31 and the flexible shaft pressure plate 8; the connecting flexible shaft 7 is connected to the output shaft of the first rotating drive member 6 and then passes through the channel to be connected to the rotating shaft of the stirring rod 41.

[0044] The utility model transmits rotational power through the connecting flexible shaft, so that the first rotating driving member 6 can be installed on the mounting plate 1, away from the top of the cooking container, avoiding the impurities generated during the rotation of the first rotating driving member 6 from falling into the cooking container, thereby improving hygiene and safety. At the same time, by setting the flexible shaft pressing plate 8, and by the flexible shaft pressing plate 8 and the opening groove 31 of the first folding arm 1 to form a channel, by limiting the connecting flexible shaft 7 in the passage, it is prevented from generating large shaking during the rotation of the connecting flexible shaft 7, causing the shaking of the device and affecting the cooking process, and also preventing the impurities generated by excessive shaking of the device from contaminating the food.

[0045] In other embodiments, a fixed pipe may be provided on the first folding arm 3 or the second folding arm 4, and the connecting flexible shaft 7 may be limited by the pipe to prevent the connecting flexible shaft 7 from shaking greatly during the rotation process, causing the shaking of the device and affecting the cooking process. Alternatively, multiple annular holes may be provided to limit the connecting flexible shaft 7 by the annular holes to prevent the connecting flexible shaft 7 from shaking greatly during the rotation process, causing the shaking of the device and affecting the cooking process. The limiting structure of the rotation action of the connecting flexible shaft 7 includes but is not limited to the above examples.

[0046] Example 3

[0050] In a specific embodiment, the second rotary drive member 21 drives the coupling 23 and then drives the square shaft 26 to rotate. Since the square shaft 26 is fixedly connected to the first folding arm 3, the first folding arm 3 is driven to rotate during the rotation of the square shaft 26, thereby realizing the rotation control of the first folding arm 3. When the first folding arm 3 rotates, the second folding arm 4 forms an active connection with the first folding arm 3 circular shaft 42 and the circular hole, and the second folding arm 4 folds with the first folding arm 3 under the action of gravity. Through a clever structural design, a rotary power source is used to realize the simultaneous folding and retracting of two folding arms, saving costs and improving the space utilization rate of the cooking process. At the same time, the state sensor 27 is used to detect whether the device is in a folded state or an unfolded stirring state.

[0053] Specifically, the cooking and stirring device further includes a second coupling 9 ; the rotating shaft of the stirring rod 41 is connected to the connecting flexible shaft 7 via the second coupling 9 .
