Description

Technical Field

[0001] This utility model relates to the field of cooking equipment, and in particular to a cooking pot. Background Technology

[0002] Cooking requires a high-temperature, high-pressure environment inside the pot. In related technologies, the lid can easily be accidentally opened during cooking, causing a sudden release of internal pressure. The resulting pressure shockwave could cause serious injury, and splattered hot food could cause extensive burns, resulting in severe trauma. There is room for improvement in these technologies.

[0029] The embodiments of this utility model are described in detail below.

Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0031] The cooking pot 1000 according to an embodiment of the present invention is described below with reference to the accompanying drawings.

[0032] like Figure 1 and Figure 2 As shown, the cooking pot 1000 according to an embodiment of the present utility model includes a pot body 200 and a pot lid 100. The pot body 200 is provided with a plurality of bottom teeth 201, one of which is a stop tooth 2011.

[0033] The cooking pot 1000 includes a pot body 200 and a lid 100. The pot body 200 defines a cooking cavity for cooking. The lid 100 cooperates with the pot body 200 to isolate the cooking cavity from the outside environment, thereby improving the stability of the cooking environment inside the pot body 200. For example, the lid 100 and pot body 200 are sealed together, creating a high-pressure environment within the cooking cavity of the pot body 200 for high-pressure cooking and improved cooking results. Alternatively, the lid 100 and pot body 200 are sealed together, creating a high-heat environment within the cooking cavity of the pot body 200 for baking food. The pot body 200 has multiple lower teeth 201, which protrude from the pot body 200 body and form multiple tooth-like structures. The lower teeth 201 can be used to cooperate with structures on the lid 100 for sealing or locking.

[0034] It is understandable that cooking inside the pot body 200 of the cooking pot 1000 requires a high-temperature, high-pressure cooking environment. In related technologies, the lid can easily be opened accidentally during cooking, causing a sudden release of internal pressure. The resulting pressure shockwave could cause serious injury, and the splattering of hot food could cause extensive burns, resulting in severe trauma to the human body. There is room for improvement in this area.

[0035] like Figures 2-4As shown, the pot lid 100 of this utility model embodiment includes a lid body 1 and a locking mechanism 2. The locking mechanism 2 includes: an opening button 21, a linkage component 22, and a locking pin 23. The opening button 21 is movably disposed on the lid body 1. The linkage component 22 is movably disposed on the lid body 1. The opening button 21 cooperates with the linkage component 22 to drive the linkage component 22 to move. The locking pin 23 is disposed on the linkage component 22. The linkage component 22 drives the locking pin 23 to move relative to the pot body 200. The locking mechanism 2 has a locked state and an unlocked state. In the locked state, the locking pin 23 abuts against the stop surface 20111 of the stop tooth 2011 to limit the rotational freedom of the pot lid 100. In the unlocked state, the opening button 21 is in a pressed state to drive the locking pin 23 to move through the linkage component 22 until the stop surface 20111 of the stop tooth 2011 is separated.

[0036] The lid 1 is the main body of the pot lid 100. The locking mechanism 2 is installed on the lid 1. The locking mechanism 2 has a locked state and an unlocked state, which can control whether the pot lid 100 can be opened to open the pot body 200.

[0037] The lid opening button 21 is movable relative to the lid 1, and the user can drive the lid opening button 21 to control the locking mechanism 2 to switch between the locked state and the unlocked state. For example, the lid opening button 21 is movable relative to the lid 1, and the user presses the lid opening button 21 to drive the lid opening button 21 to move; and for another example, the lid opening button 21 is rotatable relative to the lid 1, and the user presses the lid opening button 21 and drives the lid opening button 21 to rotate to control the lid opening button 21.

[0038] The linkage component 22 is located between the lid opening button 21 and the locking pin 23. The linkage component 22 plays a transmission role. After the lid opening button 21 is driven, the lid opening button 21 drives the linkage button to move. Then the linkage component 22 drives the locking pin 23 to move relative to the pot body 200.

[0039] The locking pin 23 is a functional component of the locking mechanism 2 for locking or unlocking. The locking pin 23 can optionally engage with the stop tooth 2011 of the pot body 200. When the locking mechanism 2 is in the locked state, the locking pin 23 abuts against the stop surface 2011 of the stop tooth 2011, thereby limiting the pot lid 100 and preventing the pot lid 100 from rotating relative to the pot body 200 to open the pot body 200. For example, one sidewall of the stop tooth 2011 can be configured as the stop surface 20111.

[0040] When it is necessary to open the pot body 200, the user needs to keep pressing the lid opening button 21 until the linkage component 22 is activated. Then, the linkage component 22 moves the locking pin 23 relative to the pot body 200 until it no longer abuts against the stop surface 20111 of the stop tooth 2011. At this point, the locking mechanism 2 switches to the unlocked state. This releases the rotational limitation of the lid 100 relative to the pot body 200. Figure 5As shown, the lid 100 can be rotated to open the pot body 200. The lines with arrows in the figure indicate the direction of rotation of the lid 100.

[0041] The locking mechanism 2 of this embodiment has at least three moving components 221: a lid-opening button 21, a linkage component 22, and a locking pin 23. Pressing the lid-opening button 21 activates it, followed by the linkage component 22, which in turn moves the locking pin 23 relative to the pot body 200. Because of the three moving components 221, a larger pressing force is required to open the lid-opening button 21, and the button must be kept pressed when switching the locking mechanism 2 to the unlocked state. Even if the lid-opening button 21 is accidentally pressed, the locking mechanism 2 will not unlock. This increased operational complexity reduces the likelihood of the pot body 200 opening due to accidental touches. Furthermore, by providing the three moving components 221, compared to a design that only drives the locking pin 23 for unlocking, the response time of the locking pin 23 is extended, further reducing the likelihood of the pot body 200 opening due to accidental touches, thereby improving the operational reliability of the cooking pot 1000.

[0042] According to the embodiment of the present invention, the cooking pot 1000, by setting a locking mechanism 2, when the locking mechanism 2 is in the locked state, stably engages the lid 100 and the pot body 200, thereby improving the working stability of the cooking pot 1000. When switching the locking mechanism 2 from the locked state to the unlocked state, the lid opening button 21 needs to be kept in the pressed state. Furthermore, by setting at least three moving components 221, including the lid opening button 21, the linkage component 22, and the locking pin 23, a relatively large pressing force is required to drive the lid opening button 21, which can reduce the possibility of accidental activation causing the pot body 200 to open. By setting the above three moving components 221, the response time of the locking pin 23 can also be extended, thereby further reducing the possibility of accidental activation causing the pot body 200 to open, thus improving the working reliability of the cooking pot 1000.

[0043] In some embodiments of this utility model, such as Figure 2 and Figure 3 As shown, the linkage component 22 includes: a movable component 221 and a connector 222. The movable component 221 is movably disposed on the cover 1. The cover opening button 21 cooperates with the movable component 221 to push the movable component 221 to move. The locking pin 23 is fixed to the connector 222. The movable component 221 moves so that the connector 222 and the locking pin 23 are movable.

[0044] The linkage component 22 includes a movable component 221 and a connector 222. The movable component 221 moves under the push of the cover opening button 21, and the movement of the movable component 221 causes the connector 222 and the locking pin 23 to move. The locking pin 23 is fixedly connected to the connector 222. By setting the connector 222, the connection stability between the locking pin 23 and the linkage component 22 can be improved, thereby improving the movement reliability of the locking mechanism 2.

[0045] Furthermore, compared to simply setting the moving component 221 to drive the locking pin 23 to move, by setting the connecting component 222 to move the locking pin 23, the connecting component 222 can drive the locking pin 23 to move or rotate in multiple directions under the drive of the moving component 221. This provides more options for the movement mode of the locking pin 23, which can be selected according to the actual layout space, thus improving the structural compactness.

[0046] In some embodiments of this utility model, such as Figure 3 and Figure 4 As shown, the connector 222 can reciprocate relative to the lid 1, and the locking pin 23 extends toward the center of the pot body 200. The connector 222 drives the locking pin 23 to reciprocate relative to the pot body 200 in the horizontal direction.

[0047] It is understandable that the lid 100 rotates relative to the pot body 200 to open the pot body 200. The locking pin 23 and the stop surface 20111 of the stop tooth 2011 stop and restrict the rotation of the lid 100. By extending the locking pin 23 toward the center of the pot body 200, the extension direction of the locking pin 23 is perpendicular to the tangential direction of the rotation of the lid 100, thereby improving the limiting effect of the locking pin 23.

[0048] When the locking mechanism 2 is in the locked state, the locking pin 23 abuts against the stop surface 20111 of the stop tooth 2011, thereby limiting the pot lid 100. The pot lid 100 cannot rotate relative to the pot body 200 to open the pot body 200.

[0049] When it is necessary to open the pot body 200, the user needs to keep pressing the lid opening button 21 until the moving component 221 is moved. Then the moving component 221 moves the connecting piece 222 in the horizontal direction. The connecting piece 222 moves the locking pin 23 relative to the pot body 200 until it no longer abuts against the stop surface 20111 of the stop tooth 2011. At this time, the locking mechanism 2 switches to the unlocked state, thereby releasing the rotation limit of the lid 100 relative to the pot body 200. The lid 100 can then be rotated to open the pot body 200.

[0050] The connector 222 drives the locking pin 23 to reciprocate in the horizontal direction relative to the pot body 200. Thus, when the locking mechanism 2 is in the unlocked state, the connector 222 can drive the locking pin 23 to move in the opposite direction, so that the locking pin 23 abuts against the side stop surface 20111 of the stop pot tooth 2011, thereby switching the locking mechanism 2 to the locked state.

[0051] By setting the connector 222 to be movable in the horizontal direction relative to the pot body 200, the space occupied in the vertical direction can be reduced, and the interference of the vertical structure on the movement of the connector 222 and the locking pin 23 can be reduced.

[0052] The following description will be based on Embodiment 1 of this utility model. Figure 3 , Figure 4 , Figure 6 and Figure 7 As shown, the lower jaw 201 on the pot body 200 protrudes outward relative to the side of the pot body 200 to stop the side of the stop jaw 2011, forming a stop surface 20111. When the locking mechanism 2 is in the locked state, the locking pin 23 is located outside the pot body 200 and abuts against the stop surface 20111 on the side of the stop jaw 2011.

[0053] When the pot body 200 needs to be opened, the connector 222 drives the locking pin 23 to move horizontally outward along the radial direction of the pot body 200 until it no longer abuts against the stop surface 20111 on the side of the stop tooth 2011. The locking mechanism 2 then switches to the unlocked state, thereby releasing the rotation limit of the lid 100 relative to the pot body 200. When the lid 100 needs to be locked to the pot body 200, the connector 222 drives the locking pin 23 to move horizontally inward relative to the radial direction of the pot body 200 until it abuts against the stop surface 20111 on the side of the stop tooth 2011. This switches the locking mechanism 2 to the locked state.

[0054] In some embodiments of this utility model, such as Figures 13-17 As shown, the connector 222 is rotatably mounted on the cover 1. The moving component 221 engages with the inclined surface of one end of the connector 222 to drive the connector 222 to rotate. The locking pin 23 is located at the other end of the connector 222. The connector 222 rotates to drive the locking pin 23 to move up and down.

[0055] The connector 222 is rotatably mounted on the cover 1. The connector 222 requires less space to rotate, which makes the structure more compact and facilitates the arrangement of the locking mechanism 2. The connector 222 rotates to drive the locking pin 23 to move up and down. When the locking pin 23 moves to abut against the stop surface 20111 of the stop tooth 2011, the locking mechanism 2 is in the locked state. When the locking pin 23 moves up or down until it is misaligned with the stop surface 20111 of the stop tooth 2011, the locking mechanism 2 is in the unlocked state.

[0056] One end of the movable component 221 facing the connector 222 engages with the inclined surface of the connector 222, thereby changing the direction of movement. For example, horizontal movement can be converted into vertical movement, thereby causing the connector 222 to rotate. By using the inclined surface engagement, the structure can be simplified compared to using multiple adapters to change the direction of force, which is beneficial to improving the structural compactness.

[0057] The following description will be based on Embodiment 2 of this utility model. Figures 13-17 As shown, the connector 222 is rotatably mounted on the cover 1 via the connector shaft 2221. The connector shaft 2221 extends in the horizontal direction, and the connector 222 rotates around the connector shaft 2221 as the rotation center. The connector 222 is constructed as a lever structure. When one end of the connector 222 in the length direction is tilted upward, the other end of the connector 222 in the length direction is pressed down.

[0058] The end of the moving component 221 near the connector 222 is constructed as a first inclined surface 221a extending from top to bottom away from the connector 222. One end of the connector 222 in the length direction is directly opposite the first inclined surface 221a, and the other end of the connector 222 in the length direction supports the locking pin 23.

[0059] When it is necessary to open the pot body 200, press the lid opening button 21 to drive the moving component 221 to move towards the connector 222. As the first inclined surface 221a approaches the connector 222, the distance between the first inclined surface 221a and the connector 222 gradually decreases, which forces the end of the connector 222 near the first inclined surface 221a to move downward, thereby causing the other end of the supporting locking pin 23 of the connector 222 to move upward until it is misaligned with the stop pot tooth 2011. The locking mechanism 2 switches to the unlocked state, thereby releasing the rotation limit of the pot lid 100 relative to the pot body 200.

[0060] Next, as Figure 18 As shown, the lid 100 can be rotated to open the pot body 200. The lines with arrows in the figure indicate the direction of rotation of the lid 100.

[0061] When it is necessary to lock the lid 100 to the pot body 200, simply move the moving component 221 away from the connector 222. The first inclined surface 221a no longer applies a downward force to the end of the connector 222 near the first inclined surface 221a, which drives the other end of the supporting locking pin 23 of the connector 222 to move downward, so that the locking pin 23 and the stop surface 20111 of the stop tooth 2011 stop the locking mechanism 2 to the locked state.

[0062] In some embodiments of this utility model, such as Figure 4 and Figure 12As shown, the moving component 221 includes: a first opening push plate 2211 and a second opening push plate 2212. The first opening push plate 2211 cooperates with the opening button 21 to be moved by the opening button 21. The moving directions of the first opening push plate 2211 and the second opening push plate 2212 intersect. The inclined surfaces of the second opening push plate 2212 and the first opening push plate 2211 cooperate to be pushed by the first opening push plate 2211. The second opening push plate 2212 cooperates with the connector 222.

[0063] The moving component 221 includes a first opening push plate 2211 and a second opening push plate 2212. After pressing the opening button 21, the first opening push plate 2211 is driven to move. Then the first opening push plate 2211 drives the second opening push plate 2212 to move. The second opening push plate 2212 then drives the connector 222 to move.

[0064] The first cover-opening push plate 2211 and the second cover-opening push plate 2212 are engaged by inclined surfaces, so that the moving directions of the first cover-opening push plate 2211 and the second cover-opening push plate 2212 intersect. Compared with setting up a whole cover-opening push plate, it can save space in the length direction of the first cover-opening push plate 2211 and the length direction of the second cover-opening push plate 2212, which facilitates the arrangement of the moving component 221.

[0065] Furthermore, by dividing the moving component 221 into a first lid-opening push plate 2211 and a second lid-opening push plate 2212 with different moving directions, the force required to drive the moving component 221 to move when the lid-opening button 21 is pressed is greater, and the response time is longer, so as to reduce the situation where the pot body 200 is opened due to accidental touch, thereby improving the working reliability of the cooking pot 1000.

[0066] The following description will be based on Embodiment 1 of this utility model. Figure 11 As shown, the surface of the first cover-opening push plate 2211 near the second cover-opening push plate 2212 is constructed as a second inclined surface 221b, and the surface of the second cover-opening push plate 2212 near the first cover-opening push plate 2211 is constructed as a third inclined surface 221c. The second inclined surface 221b and the third inclined surface 221c extend in the same direction, and the second inclined surface 221b and the third inclined surface 221c are in surface contact, thereby improving the cooperation stability of the first cover-opening push plate 2211 and the second cover-opening push plate 2212, so that the second cover-opening push plate 2212 can move stably under the drive of the first cover-opening push plate 2211.

[0067] The first opening push plate 2211 moves along its own length, while the second opening push plate 2212 extends and intersects with the first opening push plate 2211. Driven by the first opening push plate 2211, the second opening push plate 2212 moves along its own length to improve the stability of the movement. The lines with arrows in the figure indicate the moving directions of the first opening push plate 2211 and the second opening push plate 2212.

[0068] like Figure 16 As shown, the moving component 221 in Embodiment 2 of this utility model is the same as the moving component 221 in Embodiment 1. The first cover-opening push plate 2211 and the second cover-opening push plate 2212 are engaged by inclined surfaces. The first cover-opening push plate 2211 moves along its own length direction, and the second cover-opening push plate 2212 moves along its own length direction. The lines with arrows in the figure indicate the moving directions of the first cover-opening push plate 2211 and the second cover-opening push plate 2212.

[0069] In some embodiments of this utility model, the second cover push plate 2212 and the connector 222 are fixedly engaged to drive the connector 222 to reciprocate.

[0070] The second cover-opening push plate 2212 and the connector 222 are fixedly engaged, which can improve the connection stability of the second cover-opening push plate 2212 and the connector 222, thereby improving the motion stability of the second cover-opening push plate 2212 driving the connector 222 to reciprocate.

[0071] For example, the second opening push plate 2212 and the connector 222 are fixedly connected by screws. The second opening push plate drives the connector 222 to reciprocate.

[0072] In some embodiments of this utility model, the second cover push plate 2212 and the connector 222 are positioned and cooperated to drive the connector 222 to move back and forth.

[0073] The second cover-opening push plate 2212 and the connector 222 are positioned and engaged, so that the connector 222 and the second cover-opening push plate 2212 are relatively stably connected. The connector 222 can reciprocate under the drive of the second cover-opening push plate 2212. Compared with the fixed connection by fasteners, the positioning connection between the second cover-opening push plate 2212 and the connector 222 is easier to operate, which can simplify the assembly steps and improve the assembly efficiency.

[0074] In Embodiment 1 of this utility model, as Figure 12 As shown, the connector 222 has an insertion hole 2222, and the second cover push plate 2212 is provided with an insertion shaft 22121. The insertion shaft 22121 is inserted into the insertion hole 2222 to position and connect the second cover push plate 2212 and the connector 222.

[0075] In embodiment four of this utility model, as Figure 36 As shown, the connector 222 is provided with a buckle 2223, and the second cover push plate 2212 is provided with a slot 22122. The buckle 2223 and the slot 22122 are engaged to position and connect the second cover push plate 2212 and the connector 222.

[0076] In some embodiments of this utility model, such as Figures 19-23 As shown, the moving component 221 also includes a third cover-opening push plate 2213, which is fixedly engaged with the second cover-opening push plate 2212 to move synchronously with the second cover-opening push plate 2212; the third cover-opening push plate 2213 is fixedly connected to the locking pin 23 and / or the connecting piece 222 to drive the locking pin 23 to move.

[0077] The movable component 221 includes a first opening push plate 2211 and a second opening push plate 2212 that are movably engaged. The movable component 221 also includes a third opening push plate 2213, which is fixedly engaged with the second opening push plate 2212. The first opening push plate 2211 drives the second opening push plate 2212 to move, while the third opening push plate 2213 and the second opening push plate 2212 move synchronously. The third opening push plate 2213 is fixedly connected to the locking pin 23 and / or the connecting member 222 to drive the locking pin 23 to move. Thus, during the joint movement of the third opening push plate 2213 and the second opening push plate 2212, the third opening push plate 2213 drives the connecting member 222 to move.

[0078] By setting the third cover-opening push plate 2213 to be fixedly connected to the locking pin 23 and / or the connecting piece 222, the connection stability between the moving component 221 and the connecting piece 222 and / or the locking pin 23 can be improved, thereby improving the movement stability of the connecting piece 222 and / or the locking pin 23.

[0079] The following is a reference appendix. Figures 19-23 The structure and movement process of the locking mechanism 2 in Embodiment 3 of this utility model are described.

[0080] The movable component 221 includes a first opening push plate 2211, a second opening push plate 2212, and a third opening push plate 2213. The first opening push plate 2211 cooperates with the opening button 21 to be moved by the opening button 21. The moving directions of the first opening push plate 2211 and the second opening push plate 2212 intersect. The inclined surfaces of the second opening push plate 2212 and the first opening push plate 2211 cooperate to be pushed by the first opening push plate 2211. The second opening push plate 2212 and the third opening push plate 2213 are fastened together. The shape of the third opening push plate 2213 is similar to that of the connector 222, and the extending direction of the third opening push plate 2213 is the same as that of the connector 222, thereby increasing the contact area between the third opening push plate 2213 and the connector 222 and improving the stability of the third opening push plate 2213 relative to the connector 222. The third cover-opening push plate 2213 is in close contact with the connecting piece 222 and together with the connecting piece 222, it is connected to the locking pin 23. The third cover-opening push plate 2213 is fastened to the locking pin 23.

[0081] The lower jaw 201 on the pot body 200 protrudes outward relative to the pot body 200, and the side structure of the stop jaw 2011 has a stop surface 20111. When the locking mechanism 2 is in the locked state, the locking pin 23 is located on the outside of the pot body 200 and extends towards the center of the pot body 200 to abut against the stop surface 20111 on the side of the stop jaw 2011.

[0082] When it is necessary to open the pot body 200, the user needs to keep pressing the lid opening button 21. The lid opening button 21 drives the first lid opening push plate 2211 to move. Then, the first lid opening push plate 2211 drives the second lid opening push plate 2212 and the third lid opening push plate 2213 to move together. The third lid opening push plate 2213 and the connecting piece 222 together drive the locking pin 23 to move horizontally along the radial direction of the pot body 200 towards the outside of the pot body 200 until it no longer abuts against the stop surface 20111 of the stop tooth 2011. The locking mechanism 2 switches to the unlocked state, thereby releasing the rotation limit of the pot lid 100 relative to the pot body 200. Then, as Figure 21 As shown, the lid 100 can be rotated to open the pot body 200. The lines with arrows in the figure indicate the direction of rotation of the lid 100.

[0083] When it is necessary to lock the lid 100 to the pot body 200, the third lid opening push plate 2213 and the connecting piece 222 together drive the locking pin 23 to move horizontally towards the inside of the pot body 200 relative to the radial direction of the pot body 200 until it abuts against the stop surface 20111 of the stop tooth 2011, thereby switching the locking mechanism 2 to the locked state.

[0084] In some embodiments of this utility model, such as Figure 9 and Figure 10 As shown, the lid opening button 21 and the inclined surface of the first lid opening push plate 2211 cooperate to push the first lid opening push plate 2211 to move.

[0085] The lid opening button 21 and the first lid opening push plate 2211 are engaged at an angle. Compared to setting the lid opening button and the first lid opening push plate to engage along the length direction of the first lid opening push plate, this saves space along the length direction of the first lid opening push plate 2211, making it easier to arrange the lid opening button 21. Furthermore, by engaging the lid opening button 21 and the first lid opening push plate 2211 at an angle, the force required to drive the moving component 221 when the lid opening button 21 is pressed is greater, and the stroke of the lid opening button 21 is increased. This reduces the possibility of accidental opening of the pot body 200, thereby improving the operational reliability of the cooking pot 1000.

[0086] The following description will be based on Embodiment 1 of this utility model. Figure 9 and Figure 10As shown, the surface of the lid opening button 21 near the first lid opening push plate 2211 is constructed as a fourth inclined surface 221d, and the surface of the first lid opening push plate 2211 near the lid opening button 21 is constructed as a fifth inclined surface 221e. The fourth inclined surface 221c and the fifth inclined surface 221d extend in the same direction, and the fourth inclined surface 221c and the fifth inclined surface 221d are in surface contact, thereby improving the stability of the cooperation between the lid opening button 21 and the first lid opening push plate 2211, allowing the first lid opening push plate 2211 to move stably under the drive of the lid opening button 21. The first lid opening push plate 2211 moves along the length direction of the first lid opening button 21 under the drive of the lid opening button 21.

[0087] In some embodiments of this utility model, such as Figure 29 and Figure 30 As shown, the lid opening button 21 and the first lid opening push plate 2211 are positioned and engaged to fix the lid opening button 21 and the first lid opening push plate 2211 relatively. This can improve the connection stability between the lid opening button 21 and the first lid opening push plate 2211, so that the lid opening button 21 can drive the first lid opening push plate 2211 to move stably when it is pressed.

[0088] The following description will be based on Embodiment 4 of this utility model. Figure 29 and Figure 30 As shown, the upper side of the first cover-opening push plate 2211 is provided with a connecting groove 22111; the cover-opening button 21 is provided with a downward protruding protrusion 211, which extends downward into the connecting groove 22111 to engage with the connecting groove 22111. When the cover-opening button 21 is pressed, it can drive the first cover-opening push plate 2211 to move stably and synchronously.

[0089] In some embodiments of this utility model, such as Figures 24-26 As shown, the locking mechanism 2 also includes: a button reset component 24 and a pin reset component 25. The button reset component 24 cooperates with the cover 1 and the cover opening button 21 respectively to push the cover opening button 21 to reset; as shown Figure 27 and Figure 28 As shown, the pin reset component 25 cooperates with the cover body 1 and the locking pin 23 respectively, and the pin reset component 25 makes the locking pin 23 tend to move toward the stop tooth 2011.

[0090] The button reset component 24 cooperates with the lid opening button 21 and the lid 1. The button reset component 24 has a tendency to drive the lid opening button 21 to resist pressing and move towards the reset position. On the one hand, it can improve the pressure resistance of the lid opening button 21, requiring more force when pressing the lid opening button 21, thereby reducing the possibility of accidental activation of the pot body 200 and improving the working reliability of the cooking pot 1000. On the other hand, after other forces are removed from the lid opening button 21, the lid opening button 21 can be reset by the action of the button reset component 24 without manual reset, which is convenient for use.

[0091] Furthermore, by setting the button reset component 24, a noticeable rebound force will be given to the user when the cover opening button 21 is driven, which provides a good feel and makes it easy to use.

[0092] The pin reset component 25 cooperates with the lid 1 and the locking pin 23. The pin reset component 25 has a tendency to drive the locking pin 23 to engage with the stop tooth 2011. On the one hand, the greater force required to drive the locking pin 23 to move reduces the possibility of accidental opening of the pot body 200, thus improving the working reliability of the cooking pot 1000. On the other hand, after the other force applied to the locking pin 23 is removed, the locking pin 23 can be reset by the action of the pin reset component 25, limiting the lid 100 relative to the pot body 200 without manual reset. This reduces the possibility of users forgetting to put the lid 100 back on after opening it to check the contents of the pot body 200, thus improving ease of use.

[0093] In some embodiments of this utility model, the locking pin 23 is fixedly connected to the linkage component 22. The locking mechanism 2 is configured such that when the cover opening button 21 is released, the button reset component 24 pushes the cover opening button 21 to reset, and the pin reset component 25 drives the locking pin 23 to move so that the linkage component 22 is reset, and the locking mechanism 2 switches to the locking state.

[0094] The locking mechanism 2 has an automatic return-to-lock function, which reduces the likelihood that users will forget to close the lid 100 after opening it to check the contents of the pot 200, thus improving ease of use. In some embodiments of this utility model, the button reset component 24 is constructed as a spring, and the pin reset component 25 is constructed as a spring. The button reset component 24 and the pin reset component 25 have simple structures and high operational reliability.

[0095] The following description will be based on Embodiment 1 of this utility model. Figure 3 and Figure 4 As shown, when it is necessary to open the pot body 200, the user needs to keep pressing the lid opening button 21. The lid opening button 21 drives the linkage component 22 to move. The linkage component 22 drives the locking pin 23 to move horizontally along the radial direction of the pot body 200 towards the outside of the pot body 200 until it no longer abuts against the stop surface 20111 of the stop tooth 2011. The locking mechanism 2 switches to the unlocked state, thereby releasing the rotation limit of the pot lid 100 relative to the pot body 200.

[0096] When the lid opening button 21 is released, as Figure 25 and Figure 26 As shown, the button reset component 24 pushes the cover opening button 21 to reset, and the arrow in the figure indicates the direction of movement of the cover opening button 21. And as... Figure 28As shown, the pin reset component 25 drives the locking pin 23 to move horizontally along the radial direction of the pot body 200 toward the inner side of the pot body 200 until it abuts against the stop surface 20111 of the stop tooth 2011. The movement of the locking pin 23 drives the linkage component 22 to move, so that the linkage component 22 also resets. The locking mechanism 2 switches to the locking state, restricting the rotation of the pot lid 100 relative to the pot body 200.

[0097] In some embodiments of this utility model, such as Embodiment 1, Embodiment 2 and Embodiment 3, after the release of the cover opening button 21, the button reset component 24 pushes the cover opening button 21 to reset, and the pin reset component 25 can drive the locking pin 23 to move so that the linkage component 22 is reset, and the locking mechanism 2 switches to the locking state.

[0098] In some other embodiments of this utility model, the pot lid 100 includes a positioning component 3. The positioning component 3 can position the locking mechanism 2 in the unlocked state. After the lid opening button 21 is released, the locking pin 23 will not automatically stop. The pin reset component 25 can only move the locking pin 23 after the positioning component 3 is released, so that the locking mechanism 2 switches to the locked state. The advantage of this is that the lid can be opened by pressing the lid opening button 21 once, and the locking mechanism 2 is set in the unlocked state, without having to keep pressing the lid opening button 21 to open the pot lid 100, which is convenient for operation.

[0099] In some embodiments of this utility model, such as Figures 31-33 As shown, the pot lid 100 includes a positioning component 3, which is disposed on the lid body 1. When the locking mechanism 2 is in the unlocked state, it cooperates with the positioning component 3 to be positioned in the unlocked state. The cooking pot 1000 also includes a release component 300, which is adapted to cooperate with the locking mechanism 2 to release the unlocked state.

[0100] The positioning component 3 can position the locking mechanism 2 in the unlocked state. The lid can be opened simply by pressing the lid opening button 21, and the locking mechanism 2 will be in the unlocked state. It is not necessary to keep pressing the lid opening button 21 to open the pot lid 100, which makes it easier to operate.

[0101] The cooking pot 1000 also includes a release component 300. The release component 300 needs to be operated in conjunction with the locking mechanism 2 to release the locking mechanism 2 from the unlocked state positioned by the positioning component 3. Then the button reset component 24 can push the lid opening button 21 to reset. The pin reset component 25 can drive the locking pin 23 to stop against the stop surface 20111 of the stop tooth 2011, and the locking mechanism 2 can switch to the locked state.

[0102] In some embodiments of this utility model, such as Figures 33-35As shown, the positioning component 3 is rotatably mounted on the cover 1, and the positioning component 3 is provided with a positioning hook 31; the linkage component 22 is provided with a positioning protrusion 223, and the positioning protrusion 223 cooperates with the positioning hook 31 to position the linkage component 22. The cover opening button 21 is positioned and cooperates with the linkage component 22 to be relatively fixed.

[0103] The positioning component 3 is rotatably mounted on the cover 1. The positioning component 3 requires less space to rotate, making the structure more compact. The positioning component 3 is positioned and engaged with the positioning protrusion 223 of the linkage component 22 through the positioning hook 31. When the linkage component 22 moves to be positioned and engaged with the positioning component 3, the linkage component 22 is positioned and no longer moves, thereby positioning the locking mechanism 2 in the unlocked state.

[0104] The lid opening button 21 is positioned in conjunction with the linkage component 22. Therefore, when the linkage component 22 is positioned, the lid opening button 21 is also positioned, and the lid opening button 21 cannot be reset by the button reset component 24.

[0105] In some embodiments of this utility model, such as Figure 31 , Figure 32 and Figure 35 As shown, the linkage component 22 includes: a first cover-opening push plate 2211 and a second cover-opening push plate 2212. The first cover-opening push plate 2211 is fixedly engaged with the cover-opening button 21. A positioning protrusion 223 is provided on the first cover-opening push plate 2211. The second cover-opening push plate 2212 is linked with the locking pin 23. Figure 39 and Figure 40 As shown, the release component 300 includes a release protrusion 301 and a release portion 302. At least one lower jaw 201 has an outwardly protruding release protrusion 301 on its outer peripheral wall. The release portion 302 is located on the second cover push plate 2212. Figure 39 and Figure 41 As shown, the locking pin 23 cooperates with the release protrusion 301 to drive the second cover push plate 2212 to move synchronously, and the release part 302 is adapted to contact the positioning component 3 to push the positioning component 3 to rotate until it disengages from the positioning protrusion 223.

[0106] Pressing the lid opening button 21 drives the first lid opening push plate 2211 to move. Then, the first lid opening push plate 2211 drives the second lid opening push plate 2212 to move. The second lid opening push plate 2212 then drives the locking pin 23 to move, allowing the locking pin 23 to separate from the stop tooth 2011, thus unlocking the locking mechanism 2. The positioning protrusion 223 is located on the first lid opening push plate 2211. When the first lid opening push plate 2211 is positioned with the positioning component 3, it pushes the second lid opening push plate 2212 to remain stationary. Simultaneously, the locking pin 23 is positioned and cannot be reset by the pin reset component 25, thus positioning the locking mechanism 2 in the unlocked state. The lid opening button 21 is fixedly engaged with the first lid opening push plate 2211. Therefore, when the first lid opening push plate 2211 is positioned, the lid opening button 21 is also positioned and cannot be reset by the button reset component 24.

[0107] The release component 300 includes a release protrusion 301 located on the lower jaw 201 and a release portion 302 located on the second lid-opening push plate 2212. When the locking pin 23 engages with the release protrusion 301 on the outer peripheral wall of the jaw, the locking pin 23 drives the second lid-opening push plate 2212 to move toward the outside of the pot body 200. The release portion 302 on the second lid-opening push plate 2212 then moves to contact the positioning component 3, thereby pushing the positioning component 3 to rotate until it disengages from the positioning protrusion 223.

[0108] In this way, the button reset component 24 pushes the cover opening button 21 to reset, the first cover opening push plate 2211, which is fixedly engaged with the cover opening button 21, moves and resets together, the pin reset component 25 can drive the locking pin 23 to move and reset, the locking mechanism 2 switches to the locked state, and the second cover opening push plate 2212, which is linked with the locking pin 23, also moves and resets together, and the linkage component 22 also resets together.

[0109] In some embodiments of this utility model, such as Figure 39 and Figure 40 As shown, the release part 302 is a release slope 3021 provided on the second cover push plate 2212, and the release slope 3021 cooperates with the slope of the positioning component 3.

[0110] The second cover-opening push plate 2212 engages with the inclined surface of the positioning component 3. When the second cover-opening push plate 2212 is moved by the locking pin 23, the engagement between the inclined surface 3021 and the inclined surface of the positioning component 3 is released, thereby driving the positioning component 3 to rotate. The positioning hook 31 of the positioning component 3 rotates in a direction away from the positioning protrusion 223, thereby separating the positioning hook 31 from the positioning protrusion 223, and the positioning component 3 contacts the positioning restriction on the first cover-opening push plate 2211.

[0111] The following is a reference appendix. Figures 31-41 The structure and movement process of the locking mechanism 2 in Embodiment 4 of this utility model are described.

[0112] like Figure 31 As shown, the linkage component 22 includes: a movable component 221 and a connector 222. The movable component 221 is movably disposed on the cover 1. The cover opening button 21 cooperates with the movable component 221 to push the movable component 221 to move. The locking pin 23 is fixed to the connector 222. The movable component 221 moves so that the connector 222 and the locking pin 23 are movable.

[0113] like Figure 31 and Figure 32 As shown, the moving component 221 includes: a first opening push plate 2211 and a second opening push plate 2212. The opening button 21 is positioned and engaged with the first opening push plate 2211 so that the opening button 21 and the first opening push plate 2211 are relatively fixed. The moving directions of the first opening push plate 2211 and the second opening push plate 2212 intersect, and the inclined surfaces of the second opening push plate 2212 and the first opening push plate 2211 are engaged so that the second opening push plate 2211 can push the second opening push plate 2212 to move. The second opening push plate 2212 is positioned and engaged with the connecting member 222 so as to drive the connecting member 222 to reciprocate.

[0114] like Figure 33 and Figure 34 As shown, the positioning component 3 is rotatably mounted on the cover 1 via the positioning component shaft 32. The positioning component shaft 32 extends in the horizontal direction, and the positioning component 3 rotates around the positioning component shaft 32 as the rotation center. The positioning component 3 is constructed as a lever structure. When one end of the positioning component 3 in the length direction is tilted upward, the other end of the positioning component 3 in the length direction is pressed down.

[0115] like Figures 33-35 As shown, the bottom surface of the first cover-opening push plate 2211 is provided with a downwardly protruding positioning protrusion 223. The lower end face of one end of the positioning component 3 in the length direction is provided with a positioning hook 31 and extends to the lower side of the first cover-opening push plate 2211. The upper end face of the other end of the positioning component 3 in the length direction is provided with an elastic element, which abuts against the cover 1.

[0116] like Figure 31 As shown, the lower pot tooth 201 on the pot body 200 protrudes outward relative to the pot body 200, and one side of the stop pot tooth 2011 forms a stop surface 20111. When the locking mechanism 2 is in the locked state, the locking pin 23 is located outside the pot body 200 and extends towards the center of the pot body 200 to abut against the stop surface 20111 of the stop pot tooth 2011.

[0117] like Figure 32As shown, when it is necessary to open the pot body 200, press the lid opening button 21. The lid opening button 21 drives the first lid opening push plate 2211 to move, and then the first lid opening push plate 2211 drives the second lid opening push plate 2212 to move together. The second lid opening push plate 2212 drives the connecting piece 222 and the locking pin 23 to move horizontally along the radial direction of the pot body 200 towards the outside of the pot body 200 until they no longer abut against the stop surface 20111 of the stop tooth 2011. The locking mechanism 2 switches to the unlocked state, thereby releasing the rotation limit of the pot lid 100 relative to the pot body 200.

[0118] At this time, as Figure 35 As shown, the positioning protrusion 223 on the first cover-opening push plate 2211 has moved to the side of the positioning hook 31 away from the cover button 21, while the other end of the positioning component 3 in the length direction is pressed down under the action of the elastic element, and the end of the positioning component 3 in the length direction with the positioning hook 31 is tilted up, thereby firmly locking the positioning protrusion 223 and preventing the first cover-opening push plate 2211 from moving toward the cover-opening button 21.

[0119] The lid-opening button 21, which is fixedly engaged with the first lid-opening push plate 2211, is also positioned, and the lid-opening button 21 cannot be reset by the button reset member 24. The first lid-opening push plate 2211 also restricts the second lid-opening push plate 2212 from moving towards the inside of the pot body 200. Therefore, the connecting member 222 and the locking pin 23, which are fixedly engaged with the second lid-opening button 21, are also limited, and the locking pin 23 cannot be reset by the pin reset member 25, thereby positioning the locking mechanism 2 in the unlocked state.

[0120] Since the locking mechanism 2 is in the unlocked state, the lid 100 can rotate relative to the pot body 200. When the positioning component 3 needs to be released, it is only necessary to rotate the lid 100.

[0121] like Figure 37 and Figure 38 As shown, the outer peripheral wall of the stop tooth 2011 is provided with an outwardly protruding release protrusion 301. When the lid 100 rotates relative to the pot body 200, the locking pin 23 always remains in contact with the outer peripheral wall of the stop tooth 2011. Therefore, the locking pin 23 is driven by the release protrusion 301 to move horizontally along the radial direction of the pot body 200 towards the outer side of the pot body 200. The locking pin 23 then drives the connecting piece 222 and the second lid-opening push plate 2212 to move together towards the outer side of the pot body 200. Although the first lid-opening push plate 2211 restricts the movement of the second lid-opening push plate 2212 towards the inner direction of the pot body 200, it does not restrict the movement of the second lid-opening push plate 2212 towards the outer direction of the pot body 200.

[0122] like Figure 39 and Figure 40As shown, the second lid-opening push plate 2212 is provided with a release slope 3021. The release slope 3021 extends inclinedly downwards towards the locking pin 23. When the locking pin 23 drives the second lid-opening push plate 2212 to move towards the outside of the pot body 200, the release slope 3021 moves past the lower side of the other end of the positioning component 3 in the length direction. The release slope 3021 then drives the other end of the positioning component 3 in the length direction to rotate upwards. Figure 41 As shown, the length end of the positioning component 3, which is provided with the positioning hook 31, rotates downward, thereby releasing the positioning hook 31 from the positioning protrusion 223.

[0123] The positioning hook 31 clears the path of the first cover-opening push plate 2211, so that the button reset component 24 pushes the cover-opening button 21 to reset, and the first cover-opening push plate 2211, which is fixedly engaged with the cover-opening button 21, moves and resets together.

[0124] Then, when the lid 100 rotates relative to the pot body 200 until the locking pin 23 is opposite to the side of the stop tooth 2011, the pin reset component 25 can drive the locking pin 23 to move and reset. The locking pin 23 and the stop surface 2011 of the stop tooth 2011 stop and abut, the locking mechanism 2 switches to the locked state, and the second lid opening push plate 2212 and the connecting component 222, which are linked with the locking pin 23, also move and reset together.

[0125] In some embodiments of this utility model, such as Figure 42 As shown, the stop surface 20111 extends perpendicularly to the non-pot tooth region or the angle between the stop surface 20111 and the non-pot tooth region is an acute angle, and the opposite sidewalls of the remaining lower pot teeth 201 are formed as guide slopes 20121 extending toward each other in a direction away from the center of the pot body 200.

[0126] When the locking mechanism 2 is in the locked state, the locking pin 23 abuts against the stop surface 20111, thereby restricting the rotation of the lid 100 relative to the pot body 200. By setting the stop surface 20111 to be perpendicular to the non-tooth area of ​​the pot body 200, the stability of the fit between the locking pin 23 and the stop surface 20111 can be improved, and the locking pin 23 cannot slide onto the outer peripheral wall of the stop tooth 2011 through the side of the stop tooth 2011.

[0127] Alternatively, the stop surface 20111 can be configured to intersect with the non-pot tooth area of ​​the pot body 200 at an acute angle, which can improve the stability of the fit between the locking pin 23 and the stop surface 20111, and prevent the locking pin 23 from sliding onto the outer peripheral wall of the stop pot tooth 2011 through the side of the stop pot tooth 2011.

[0128] It is worth noting that the stop surface 20111 is interpreted in a broad sense. The stop surface 20111 can not only be a plane, but also a curved surface with an arc. The line connecting the two ends of the stop surface 20111 can extend perpendicularly to the non-tooth area or the angle between the stop surface 20111 and the non-tooth area can be an acute angle.

[0129] The side walls of the remaining lower pot teeth 201, except for the stop pot tooth 2011, are formed as guide slopes 20121. The locking pin 23 can slide down the outer peripheral wall of the lower pot teeth 201 through the side of these lower pot teeth 201, thereby finding the sealing position where the pot lid 100 and the pot body 200 are matched by rotating the pot lid 100.

[0130] The following description uses Embodiment 1 of this utility model as an example. Figure 2 and Figure 3 As shown, one side of the stop tooth 2011 is formed as a stop surface 20111 perpendicular to the non-tooth area of ​​the pot body 200. When the locking mechanism 2 is in the locked state, the locking pin 23 abuts against the stop surface 20111, thereby restricting the rotation of the pot lid 100 relative to the pot body 200. Furthermore, by setting the stop surface 20111 to be perpendicular to the non-tooth area of ​​the pot body 200, the stability of the engagement between the locking pin 23 and the stop surface 20111 can be improved, and the locking pin 23 cannot slide onto the outer peripheral wall of the stop tooth 2011 via its side.

[0131] In some embodiments of this utility model, such as Figures 43-46 As shown, the linkage component 22 is provided with a locking hole 224; the locking mechanism 2 also includes a locking float 26, which is movably disposed on the pot lid 100. The locking float 26 is configured to float upward under the pressure inside the pot body 200. When the locking mechanism 2 is in the unlocked state, the locking float 26 sinks to be located below the locking hole 224 to avoid the movement trajectory of the linkage component 22. In the locked state, the locking float 26 is located inside the locking hole 224.

[0132] When the pressure inside the pot body 200 is high, the locking float 26 rises and is positioned within the locking hole 224. This limits the movement of the linkage component 22, preventing it from moving. Consequently, the locking pin 23 connected to the linkage component 22 is also limited, preventing the locking mechanism 2 from switching from the locked state. Therefore, the pot lid 100 cannot be opened when the pressure inside the pot body 200 is high, avoiding the danger caused by a sudden release of pressure inside the pot body 200.

[0133] When the pressure inside the pot body 200 is low, the locking float 26 sinks to the bottom of the locking hole 224. The locking float 26 does not interfere with the movement of the linkage component 22, and the locking mechanism 2 can freely switch between the locked state and the unlocked state.

[0134] In some embodiments of this utility model, such as Figure 44 and Figure 46 As shown, the locking float 26 is provided with a gas channel 261. When the locking float 26 sinks, the gas channel 261 opens; when the locking float 26 rises, the locking float 26 cooperates with the cover 1 to seal the gas channel 261.

[0135] The locking float 26 is equipped with a gas channel 261. When the pressure inside the pot body 200 is low, the locking float 26 sinks, and the gas channel 261 opens, balancing the pressure inside and outside the pot body 200, allowing the lid 100 to be opened freely. When the pressure inside the pot body 200 is high, the locking float 26 rises and cooperates with the lid 1 to seal the gas channel 261, thereby sealing the inside of the pot body 200 and maintaining a high-pressure environment inside the pot body 200.

[0136] In some embodiments of this utility model, such as Figure 43 As shown, the cooking pot 1000 also includes an alarm float 27, which is configured to float upward under the pressure inside the pot body 200. When the pressure inside the pot body 200 is high, the alarm float 27 floats up to remind the user that the cooking pot 1000 is under high pressure and should not be opened rashly; when the pressure inside the pot body 200 is low, the alarm float sinks to indicate to the user that the pressure inside the cooking pot 1000 is low and the lid 100 can be opened.

[0137] In some embodiments of this utility model, such as Figure 47 As shown, the pot lid 100 is provided with an exhaust valve 4 and an exhaust mechanism 5. The exhaust mechanism 5 is configured to open the exhaust valve 4 so that the cooking cavity inside the pot body 200 can communicate with the external environment.

[0138] The lid 100 can be used to seal the cooking cavity. When the cooking pot 1000 is working, the water in the cooking cavity is heated to generate steam. Considering that if the steam cannot be discharged and continues to accumulate in the cooking cavity, the pressure inside the cooking pot 1000 will continue to rise, which may cause the cooking pot 1000 to explode, the lid 1 is equipped with an exhaust valve 4 and an exhaust mechanism 5. The exhaust mechanism 5 can open the exhaust valve 4 to connect the cooking cavity with the external environment, so that the steam in the cooking cavity can be discharged to the external environment, thereby reducing the pressure inside the cooking pot 1000.

[0139] It should be noted that "external environment" refers to the environment outside the cooking pot 1000, which can be an indoor or outdoor environment.

[0140] In some embodiments of this utility model, such as Figure 48 and Figure 49As shown, the exhaust mechanism 5 includes an exhaust trigger 51 and an exhaust linkage 52. The exhaust trigger 51 and the exhaust linkage 52 are respectively movably disposed on the lid. The exhaust trigger 51 can be triggered to drive the exhaust linkage 52 to move. The first end of the exhaust linkage 52 is disposed opposite to the exhaust valve 4 to at least push the exhaust valve 4 to move so that the cooking cavity inside the pot is connected to the external environment. When the exhaust mechanism 5 is in the exhaust state, the exhaust trigger 51 and the exhaust linkage 52 are positioned to position the exhaust linkage 52.

[0141] For example, when it is necessary to depressurize the cooking pot 100, the user can trigger the exhaust trigger 51 to switch the exhaust mechanism 5 to the exhaust state. At this time, the exhaust trigger 51 can drive the exhaust linkage 52 to push the exhaust valve 4, so that the exhaust valve 4 moves to connect the cooking chamber inside the pot with the external environment, and the steam in the cooking chamber is discharged to the external environment.

[0142] In some examples, the first end of the exhaust linkage 52 can engage with the exhaust valve 4 to allow the exhaust linkage 52 to push the exhaust valve 4 to move. For example, the exhaust linkage 52 can be constructed as a lever, which can drive the exhaust linkage 52 to rotate when the exhaust trigger 51 is triggered. As the exhaust linkage 52 rotates, it can push the exhaust valve 4 to move in the direction engaged with the exhaust linkage 52, so that the cooking cavity can be connected to the external environment. Alternatively, the exhaust linkage 52 can also be constructed as a swinging rod, which can drive the exhaust linkage 52 to swing horizontally when the exhaust trigger 51 is triggered. The first end of the exhaust linkage 52 can engage with the exhaust valve 4 through a beveled structure. During the swinging process of the exhaust linkage 52, the beveled structure can press against the exhaust valve 4 to move the exhaust valve 4, thereby allowing the exhaust valve 4 to connect the cooking cavity to the external environment.

[0143] It is understood that the above-mentioned cooperation method between the exhaust linkage 52 and the exhaust valve 4 is only an example for ease of understanding and should not be construed as a limitation of this application. The specific cooperation method between the exhaust linkage 52 and the exhaust valve 4 can be determined according to actual production requirements and is not specifically limited here.

[0144] When the exhaust mechanism 5 is in the exhaust state, that is, when the exhaust trigger 51 is triggered and drives the exhaust linkage 52 to move to the position where the cooking cavity inside the pot is connected to the external environment by the exhaust valve 4, the exhaust trigger 51 and the exhaust linkage 52 are positioned and cooperated so that the exhaust valve 4 is positioned by the exhaust linkage 52, so that the pressure inside the cooking pot 100 can be continuously discharged, which is beneficial to improving exhaust efficiency and eliminating the need for the user to continuously trigger the exhaust trigger 51, thus improving the convenience of use and improving the user experience.

[0145] like Figure 49 and Figure 50 As shown, the linkage component 22 is provided with a first mating part 225, which is adapted to cooperate with the exhaust linkage component 52 to push the exhaust linkage component 52 to release the positioning cooperation with the exhaust trigger component 51, so that the exhaust mechanism 5 can be reset to disengage from the exhaust valve 4.

[0146] The linkage component 22 is provided with a first mating part 225. Under the push of the first mating part 225, the exhaust linkage component 52 and the exhaust trigger component 51 can be disengaged. The exhaust linkage component 52 and the exhaust trigger component 51 are separated, so the exhaust valve 4 can drive the exhaust linkage component 52 to seal the cooking cavity from the external environment.

[0147] In some embodiments of this utility model, such as Figure 49 and Figure 50 As shown, the first mating component 225 is provided with a mating inclined surface 2251, and the exhaust linkage component 52 is provided with a mating protrusion 525. The mating inclined surface 2251 and the mating protrusion 525 cooperate to push the exhaust linkage component 52 to rotate.

[0148] When the linkage component 22 moves, the mating inclined surface 2251 of the first mating component 225 engages with the mating protrusion 525, thereby driving the exhaust linkage to rotate, and the exhaust linkage component 52 can disengage from the positioning engagement with the exhaust trigger component 51.

[0149] The linkage component 22 is part of the locking mechanism. During the process of switching the locking mechanism from the locked state to the unlocked state, the linkage component 22 moves to engage the mating inclined surface 2251 with the mating protrusion 525. During this process, the exhaust linkage component 52 separates from the exhaust trigger component 51, thereby releasing the positioning engagement between the exhaust linkage component 52 and the exhaust trigger component 51. The pushing action of the exhaust linkage component 52 on the exhaust valve 4 disappears, and the exhaust valve 4 can fall and close the cooking cavity, thus achieving the reset of the exhaust mechanism 5.

[0150] In some embodiments of this utility model, such as Figure 51 and Figure 52 As shown, the locking pin 23 is adapted to slide with the outer peripheral surface of the lower jaw 201 so that the first mating part 225 engages with the exhaust linkage part 52 to push the exhaust linkage part 52 to release the positioning engagement with the exhaust trigger part 51.

[0151] When the lid 100 is screwed on, the locking pin 23 moves under the guidance of the outer circumferential surface of the lower jaw 201. The movement of the locking pin 23 drives the linkage component 22 to move synchronously. The linkage component 22 can drive the first mating part 225 to move to engage with the exhaust linkage component 52, thereby pushing the exhaust linkage component 52 to disengage from the exhaust trigger component 51. The pushing effect of the exhaust linkage component 52 on the exhaust valve 4 disappears, and the exhaust valve 4 can fall and close the cooking cavity, thereby resetting the exhaust mechanism 5 and allowing the cooking cavity to be closed again.

[0152] Other components of the cooking pot according to the embodiments of the present invention, such as the warning float and its operation, are known to those skilled in the art and will not be described in detail here.
