Description

Technical Field

[0001] The utility model belongs to the technical field of kitchen appliances, and in particular relates to a cooking utensil. Background Art

[0002] Pressure cooking appliances, such as electric pressure cookers, are common cooking appliances in home kitchens. However, electric pressure cookers are usually only capable of pressure cooking, and cannot perform normal pressure cooking. When performing simpler cooking procedures such as steaming rice and cooking porridge, the electric pressure cooker will still pressurize and complete the cooking under pressure. In this way, the electric pressure cooker will perform the pressure increase and pressure relief procedures every time it cooks, which increases the overall cooking time. If users want to use normal pressure cooking, they can only purchase cooking appliances such as normal pressure rice cookers separately.

[0003] In recent years, a multifunctional cooking device has emerged, which can realize pressure cooking and be used as an electric pressure cooker, and can also realize normal pressure cooking and be used as an ordinary rice cooker, integrating pressure cooking and normal pressure cooking in one machine, greatly improving the user experience. The working principle of this multifunctional cooking device is that a vent pipe is provided on the pot cover, and a part of the vent pipe can be driven by a driving device to float up and down, thereby connecting the pot environment with the outside world through the vent pipe. When cooking in this state, the inside and outside of the pot are always connected, thereby realizing normal pressure cooking; or the vent pipe is at least partially moved to isolate the pot environment, so that the pot environment is isolated from the outside world at the vent pipe, and the pot can be normally pressurized during cooking to realize pressure cooking.

[0004] In the prior art, the method of driving the vent tube to float up and down is generally to rotate the pot cover. However, this operation is too simple and not very prompt. Moreover, rotating the pot cover is one of the operation methods that users are more familiar with and have formed a habit. Therefore, although the operation is relatively convenient, the vent tube is too sensitive to maintain a stable position. Once the pot cover is rotated, the vent tube responds immediately. In actual use, users often rotate the pot cover due to misoperation, thereby causing the vent tube to move, destroying the pressurized or non-pressurized environment in the pot and affecting normal cooking. Utility Model Content

[0005] The utility model provides a cooking utensil to solve the problem that the operation mode of the existing multifunctional cooking utensil is too simple and the user is prone to misoperation, resulting in mis-switching of the cooking state of the cooking utensil.

[0006] The technical solution adopted by the utility model is:

[0007] A cooking utensil comprises a pot body with a cooking cavity and a pot cover, the pot cover is provided with a pressure conversion member, at least part of the pressure conversion member can float up and down relative to the pot cover so as to have a pressure-free mode and a pressure-containing mode, the pot cover is also provided with an operating handle, the operating handle has a driving part, and a locking position and an unlocking position arranged up and down are provided inside the pot cover, the locking position is provided with a limiting member used to stop the driving part to limit the rotation of the operating handle, and the unlocking position is provided with a transmission member that cooperates with the driving part and is used to drive the pressure conversion member to float up and down, and the operating handle can move up and down to switch the driving part between the locking position and the unlocking position.

[0008] The cooking utensil of the present invention also has the following additional technical features:

[0009] The pot cover is also provided with a guide channel connected with the unlocking position, and the transmission member is arranged in the guide channel. When the operating handle is rotated in the unlocking position, the driving part drives the transmission member to move along the guide channel to drive the pressure conversion member.

[0010] The pressure conversion component includes a vent pipe, a vent hole is opened at the lower end of the vent pipe, a transmission protrusion is arranged on the outer wall of the vent pipe, the transmission component has an action end located below the transmission protrusion, and the action end is provided with a lifting slope matched with the transmission protrusion. When the transmission component moves toward the vent pipe, the lifting slope pushes the transmission protrusion to make the vent pipe float upward.

[0011] An elastic member is also arranged in the guide channel, and the elastic member is used to apply a thrust to the transmission member away from the pressure conversion member.

[0012] The transmission member also has a trigger end for cooperating with the driving part for transmission, and a matching inclined surface is arranged on the side opposite to the driving part and the trigger end.

[0013] The transmission member comprises a connecting part rotatably connected to the pot cover, a first transmission part located on one side of the connecting part, and a second transmission part located on the other side of the connecting part. The first transmission part is used to cooperate with the driving part, and the second transmission part is used to drive the pressure conversion part. The transmission member can rotate around the connecting part to drive the pressure conversion part.

[0014] The unlocking position and the locking position are arranged up and down, and the limiting member is located above or below the transmission member. When the driving part cooperates with the transmission member, the limiting member stops the driving part to limit the driving part to the unlocking position.

[0015] The unlocking position is located below the locking position. An elastic reset member is provided between the operating handle and the pot cover. The elastic reset member is used to apply an upward thrust to the operating handle so that the driving part switches from the unlocking position to the locking position.

[0016] The operating handle also includes a handle body, the handle body and the driving part are an integrally formed structure, and the driving part is located inside the pot cover; or, the driving part and the handle body are separately formed structures, at least a portion of the driving part is located inside the pot cover, and the driving part also has an operating end located outside the pot cover.

[0017] The pot cover comprises a cover body and a locking cover, and the operating handle can rotate to drive the locking cover to rotate relative to the cover body, so that the pot cover has a locking state in which it is locked with the pot body, and an unlocking state in which it is unlocked with the pot body.

[0018] Due to the adoption of the above technical solution, the beneficial effects achieved by the utility model are as follows:

[0019] 1. In the utility model, the pressure conversion element on the pot cover can float up and down relative to the pot cover so that the cooking appliance has a non-pressure mode and a pressure mode. In the non-pressure mode, the cooking cavity is connected to the outside atmosphere through the pressure conversion element, and the pot is in a normal pressure state. In the pressure mode, the cooking cavity is isolated from the pressure conversion element, so that the cooking appliance can be normally pressurized for pressure cooking. Thus, the multifunctional integration of pressure cooking and normal pressure cooking is achieved through one cooking appliance, which improves the user experience.

[0020] In addition, the pot cover has a locking position and an unlocking position inside, and the operating handle has a driving part. The operating handle can move up and down to switch the driving part between the unlocking position and the locking position. When the driving part is in the locking position, the limiter and the driving part stop to limit the rotation of the operating handle, and the operating handle cannot be rotated at this time. When the driving part is in the unlocking position, the driving part is not blocked so that the operating handle can rotate normally. As the operating handle rotates, the driving part drives the transmission part to make the pressure conversion part float up and down and switch between the pressure mode and the pressure-free mode. In this way, when the user adjusts the state of the pressure conversion part, he cannot simply turn the pot cover, but needs two steps. In the initial state, the driving part is in the locking position and the operating handle cannot be rotated. During operation, first lift or press down the operating handle to switch the driving part from the locking position to the unlocking position, and then rotate the operating handle to complete the driving of the pressure conversion part. Thereby providing a more stable switching structure and operation method with a lower probability of user misoperation and stronger prompting for user operation.

[0021] 2. As a preferred embodiment of the utility model, the pot cover is also provided with a guide channel connected to the unlocking position, and the transmission member is arranged in the guide channel. When the operating handle is rotated in the unlocking position, the driving unit drives the transmission member to move along the guide channel to drive the pressure conversion member. When the driving unit is in the unlocking position, by rotating the operating handle, the driving unit rotates with the operating handle, thereby forming a horizontal thrust on the transmission member, causing the transmission member to move horizontally, thereby driving the pressure conversion member to move. The horizontally moving transmission member makes the movement simpler and more reliable, and also saves space in the height direction of the pot cover, which helps to reduce the thickness of the pot cover and realize a lightweight design. The guide channel can play a guiding and limiting role in the movement of the transmission member, so that it reciprocates in the guide channel, thereby improving the movement reliability.

[0022] 3. As a preferred embodiment of the utility model, the pressure conversion element includes a vent pipe, a vent hole is provided at the lower end of the vent pipe, a transmission protrusion is provided on the outer wall of the vent pipe, the transmission element has an action end located below the transmission protrusion, and the action end is provided with a lifting slope matched with the transmission protrusion. When the transmission element moves toward the vent pipe, the lifting slope pushes the transmission protrusion to make the vent pipe float upward. In this embodiment, the transmission element drives the vent pipe to float up and down as a whole by cooperating with the transmission protrusion. Compared with the method of extending into the vent pipe to drive the internal valve core to move, the surface of the vent pipe does not need to be provided with an opening for the transmission element to extend into, thereby ensuring the sealing of the exhaust channel in the vent pipe, and also avoiding the problem of failure caused by the internal valve core being stuck to the soup and unable to move. The vent pipe can float as a whole, which greatly simplifies the structure of the vent pipe, and the transmission element drives the vent pipe more simply and conveniently, and the cooperation is more reliable.

[0023] 4. As a preferred embodiment of the present invention, the limiter is located above or below the transmission member, and when the drive unit cooperates with the transmission member, the limiter and the drive unit stop to limit the drive unit to the unlocked position. When the drive unit switches to the unlocked position and drives the transmission member, the limiter forms a vertical limit on the drive unit to keep the drive unit in the unlocked position, so that when the user operates the operating handle, once the operating handle is pressed or pulled to make the drive unit enter the unlocked position and cooperate with the transmission member, the user can stop applying vertical force and only turn the operating handle without applying vertical force to the operating handle all the time, which makes the user's operation more labor-saving and improves the user experience.

[0024] 5. As a preferred embodiment of the present invention, the pot cover includes a cover body and a lock cover, and the operating handle can rotate to drive the lock cover to rotate relative to the cover body, so that the pot cover has a locked state locked with the pot body, and an unlocked state unlocked with the pot body. When the user operates the operating handle to rotate the pot cover, the position switching of the pressure conversion component and the state switching of the pot cover and the pot body can be realized synchronously. For example, in the initial state, the pressure conversion component falls in a pressure-free mode, and the pot cover and the pot body are in an unlocked state. When the user turns the operating handle, the pressure conversion component is driven to float up and switch to a pressure mode. At the same time, the pot cover and the pot body are locked, thereby achieving one-step operation to complete the locking of the pot cover and the switching of the cooking mode of the cooking utensil, simplifying the user's operating steps and improving the user experience. In this embodiment, the operating handle also needs to move up and down first, so that the driving part enters the unlocked position, and the operating handle can drive the lock cover to rotate.

In the description of this specification, the description with reference to the terms "implementation method", "example", "one embodiment", "example" or "specific example" means that the specific features, structures, materials or characteristics described in conjunction with the embodiment or example are included in at least one embodiment or example of the utility model. In this specification, the schematic representation of the above terms does not necessarily refer to the same embodiment or example. Moreover, the specific features, structures, materials or characteristics described may be combined in an appropriate manner in any one or more embodiments or examples.

[0050] like Figure 1 , Figure 2 , Figure 5 As shown, a cooking utensil comprises a pot body with a cooking cavity and a pot cover 1, the pot cover 1 is provided with a pressure conversion member 3, at least part of the pressure conversion member 3 can float up and down relative to the pot cover 1 so as to have a pressure-free mode and a pressure-containing mode, the pot cover 1 is further provided with an operating handle 2, the operating handle 2 has a driving part 21, a locking position 13 and an unlocking position 14 are provided inside the pot cover 1, the locking position 13 is provided with a limiting member 4 for stopping the driving part 21 to limit the rotation of the operating handle 2, the unlocking position 14 is provided with a transmission member 5 which cooperates with the driving part 21 and is used to drive the pressure conversion member 3 to float up and down, and the operating handle 2 can move up and down to switch the driving part 21 between the locking position 13 and the unlocking position 14.

[0051] In the utility model, the pressure conversion member 3 on the pot cover 1 can float up and down relative to the pot cover 1 so that the cooking device has a non-pressure mode and a pressure mode. In the non-pressure mode, the cooking cavity is connected to the outside atmosphere through the pressure conversion member 3, and the pot is in a normal pressure state. In the pressure mode, the cooking cavity is isolated from the pressure conversion member 3, so that the cooking device can be normally pressurized and pressure cooking can be performed. Thus, the multifunctional integration of pressure cooking and normal pressure cooking is achieved through one cooking device, and the user experience is improved.

[0052] It is understandable that the pot cover 1 is also provided with a float valve and an exhaust pipe 11, and a weight 12 is provided at the upper end of the exhaust pipe 11. Preferably, when the pressure conversion member 3 is in the falling position, the pressure conversion member 3 connects the cooking cavity with the outside atmosphere, and the gas in the pot can be discharged out of the pot in time to ensure that the pot is in a normal pressure environment. Among them, preferably, the flow area of ​​the connecting channel of the pressure conversion member 3 is larger than the exhaust pipe 11 and the float valve, so that most of the gas in the pot is discharged from the pressure conversion member 3. Even if the float valve floats up and closes under the push of the gas in the pot, and the exhaust pipe 11 is blocked by the weight 12, the gas in the pot can still be discharged in time through the pressure conversion member 3. Specifically, when the cooking appliance is in the pressure-free mode, the gas in the pot can be discharged only through the pressure conversion member 3, or can be discharged through the pressure conversion member 3, the float valve and the exhaust pipe 11 together.

[0053] When the pressure conversion element 3 is in the floating position, the pressure conversion element 3 is isolated from the cooking cavity, so that the gas in the pot cannot be discharged through the pressure conversion element 3. At this time, the cooking appliance is in the same pressure-up manner as a conventional pressure cooker. As the temperature in the pot increases, the gas in the pot increases, and the gas gradually pushes the float valve upward to block it, and the exhaust pipe 11 is also blocked by the weight 12. Thus, the environment in the pot is completely isolated from the outside atmosphere, and pressure cooking is performed in the pot.

[0054] In addition, the pot cover 1 has a locking position 13 and an unlocking position 14 inside, and the operating handle 2 has a driving part 21. The operating handle 2 can move up and down to switch the driving part 21 between the unlocking position 14 and the locking position 13. When the driving part 21 is located at the locking position 13, the limiting member 4 and the driving part 21 are blocked to limit the rotation of the operating handle 2, and the operating handle 2 cannot rotate at this time. When the driving part 21 is located at the unlocking position 14, the driving part 21 is not blocked so that the operating handle 2 can rotate normally. As the operating handle 2 rotates, the driving part 21 drives the transmission member 5 to make the pressure conversion member 3 float up and down and switch between the pressure mode and the pressure-free mode.

[0055] In this way, when the user adjusts the state of the pressure conversion member 3, he cannot simply turn the pot cover 1, but needs to operate in two steps. In the initial state, the driving part 21 is located in the locking position 13, and the operating handle 2 cannot be rotated. When operating, first lift up or press down the operating handle 2 to switch the driving part 21 from the locking position 13 to the unlocking position 14, and then turn the operating handle 2 to complete the driving of the pressure conversion member 3. Thus, a more stable switching structure and operation method with a lower probability of user misoperation and a stronger user operation prompt is provided.

[0056] Preferably, if Figure 3As shown, the unlocking position 14 and the locking position 13 are arranged up and down to conform to the up and down movement of the operating handle 2, so that the switching of the driving part 21 between the locking position 13 and the unlocking position 14 is more reliable. Of course, the locking position 13 and the unlocking position 14 can also be arranged in other forms, such as being arranged in the same plane, and the operating handle 2 is provided with two driving parts 21 correspondingly, and the position change of the two driving parts 21 is realized by the up and down movement of the operating handle 2, so that at least one of them enters the unlocking position 14. For example, two driving parts can be provided on the operating handle 2 corresponding to the unlocking position 14 and the locking position 13, respectively, and the heights of the two driving parts are different. In the initial state, one of the driving parts is located at the locking position 13, and is stopped by the limiter 4 to limit the rotation of the operating handle 2. When the user presses down or lifts up the operating handle 2, the driving part located in the locking position 13 moves out of the locking position, and the other driving part reaches the unlocking position 14, so that the pressure conversion part 3 can be driven by the rotation of the operating handle 2.

[0057] Taking the unlocking position 14 as an example, the driving part is located at the locking position 13 in the initial state, and the operating handle 2 cannot be rotated. When the user operates, he needs to press the operating handle 2 first to move the driving part 21 down to the unlocking position 14, and then rotate the operating handle 2. In the embodiment where the unlocking position 14 is located above the locking position 13, before rotating the operating handle 2, the user only needs to pull the operating handle 2 upward to make the driving part 21 enter the unlocking position 14 above, and the operation is also simple and convenient.

[0058] The operating handle 2 moves up and down so that it does not change its position laterally, and there is no need to reserve a lateral movement space for the operating handle 2 in the pot cover 1, thereby improving the compactness and reliability of the structure and preventing the parts of the pot cover 1 from being loose. In other embodiments, the operating handle 2 can also move laterally to switch the driving part 21 between the unlocking position 14 and the locking position 13, which is not limited here.

[0059] It should be noted that the present invention does not limit the movement mode of the transmission member 5, which can be one of the following embodiments:

[0060] Implementation method 1: In this implementation method, Figure 3 , Figure 4 , Figure 6 , Figure 7 As shown, the pot cover 1 is also provided with a guide channel 15 connected to the unlocking position 14, and the transmission member 5 is arranged in the guide channel 15. When the operating handle 2 is rotated in the unlocking position 14, the driving part 21 drives the transmission member 5 to move along the guide channel 15 to drive the pressure conversion member 3.

[0061] When the driving part 21 is located at the unlocking position 14, by rotating the operating handle 2, the driving part 21 rotates with the operating handle 2, thereby forming a horizontal thrust on the transmission member 5, causing the transmission member 5 to move horizontally, thereby driving the pressure conversion member 3 to move. The horizontally moving transmission member 5 is simpler and more reliable to move, while also saving space in the height direction of the pot cover 1, which helps to reduce the thickness of the pot cover 1 and achieve a thin and light design. The guide channel 15 can guide and limit the movement of the transmission member 5, so that it reciprocates in the guide channel 15, thereby improving the movement reliability.

[0062] Specifically, Figure 6 , Figure 7 As shown, when the driving part 21 enters the unlocking position 14, as the operating handle 2 rotates, the driving part 21 gradually forms a lateral thrust on the transmission member 5 and the thrust gradually increases, causing the transmission member 5 to move horizontally in a direction close to the pressure conversion member 3, thereby triggering the pressure conversion member 3.

[0063] This embodiment does not limit the floating mode of the pressure conversion element 3. In one embodiment, the pressure conversion element 3 has a communication channel and a valve core inside. The transmission element 5 extends into the pressure conversion element 3 and cooperates with the valve core to drive the valve core to float up and down to achieve the conduction or closure of the communication channel. As a preferred embodiment, Figures 2 to 7 As shown, the pressure conversion component 3 includes a vent pipe 31, a vent hole 312 is opened at the lower end of the vent pipe 31, a transmission protrusion 311 is arranged on the outer wall of the vent pipe 31, and the transmission component 5 has an action end located below the transmission protrusion 311, and the action end is provided with a lifting slope 51 cooperating with the transmission protrusion 311. When the transmission component 5 moves toward the vent pipe 31, the lifting slope 51 pushes the transmission protrusion 311 to make the vent pipe 31 float upward.

[0064] It is understandable that if Figure 4 , Figure 7 As shown, a seal 313 is provided at the lower end of the vent pipe 31. When the vent pipe 31 is in the falling position, the vent hole 312 is located in the cooking cavity and communicates with the cooking cavity, and the seal 313 is loosened from the pot cover 1. When the vent pipe 31 is in the floating position, the vent hole 312 enters the through hole of the pot cover 1 and abuts against the inner wall of the through hole, and the seal 313 abuts against the lower surface of the pot cover 1 to achieve sealing.

[0065] In this embodiment, the transmission member 5 drives the vent pipe 31 to float up and down as a whole by cooperating with the transmission protrusion 311. Compared with the method of extending into the vent pipe 31 to drive the internal valve core to move, the surface of the vent pipe 31 does not need to have an opening for the transmission member 5 to extend into, thereby ensuring the sealing of the exhaust channel in the vent pipe 31, and also avoiding the problem of the internal valve core being unable to move due to the sticking of the soup and causing failure. The vent pipe 31 can float as a whole, which greatly simplifies the structure of the vent pipe 31, and the transmission member 5 drives the vent pipe 31 more simply and conveniently, and the cooperation is more reliable.

[0066] Specifically, the bottom end of the lifting slope 51 is always located below the transmission protrusion 311. As the transmission member 5 moves toward the vent pipe 31, the transmission protrusion 311 gradually slides to the top along the bottom end of the lifting slope 51, thereby being lifted. By cooperating with the lifting slope 51 and the transmission protrusion 311, the horizontal movement of the transmission member 5 can be converted into a vertical drive for the vent pipe 31, making the movement of the vent pipe 31 more reliable.

[0067] Furthermore, if Figure 4 , Figure 7 As shown, an elastic member 7 is further provided in the guide channel 15 , and the elastic member 7 is used to apply a thrust to the transmission member 5 away from the pressure conversion member 3 .

[0068] On the one hand, the elastic member 7 can push the transmission member 5 to reset, causing the ventilation tube 31 to fall and reset, and return to the pressure-free mode. On the other hand, the transmission member 5 can form a driving force on the driving part 21, so that the user can obtain force feedback when operating the operating handle 2, which not only improves the user's operating feel, but also can cause the operating handle 2 to reset when the user stops applying the rotational force, so that the driving part 21 switches to the locking position 13 to prevent accidental triggering.

[0069] It should be noted that the present invention does not limit the way in which the vent pipe 31 is reset. After the transmission member 5 stops pushing the vent pipe 31 and moves away from the vent pipe 31, the vent pipe 31 can fall and reset by its own gravity. Figure 3 , Figure 6 As shown, a reset member 6 is also provided at the vent pipe 31, and the reset member 6 abuts against the upper side of the transmission protrusion 311 to apply a downward thrust to the vent pipe 31, so that the vent pipe 31 falls and resets. When the user does not operate, the cooking appliance is always in a pressure-free mode and connected to the outside atmosphere, thereby avoiding abnormal pressure and ensuring safety.

[0070] Specifically, when the vent 31 moves upward, the seal 313 at the lower end abuts against the pot cover 1 for sealing, which is the pressure mode. When the vent 31 moves downward, the seal 313 and the pot cover 1 are separated from the seal, and the vent hole 312 connects the cooking cavity with the outside world, which is the pressure-free mode. In the initial state, the vent 31 is in a falling state, and the cooking utensil is in the pressure-free mode. When the user switches to the pressure mode, the operating handle 2 needs to be moved up and down first, so that the driving part 21 enters the unlocking position 14, and then the operating handle 2 can be turned to drive the vent 31 to move upward and remain in the pressure mode. When switching from the pressure mode to the pressure-free mode, the driving part 21 is already in the unlocking position 14, so there is no need to operate the operating handle 2 up and down, and the operating handle 2 can be directly turned, and the driving part 21 is pushed to switch to the locking position 13 under the action of the elastic member 7, and then in the process of the user turning the operating handle 2, the operating handle 2 naturally completes the movement reset in the up and down direction, without the user applying additional force.

[0071] In a preferred embodiment, Figure 3 , Figure 6 , Figure 8 , Fig. 9 As shown, the transmission member 5 also has a trigger end for cooperating with the driving part 21 for transmission, and a matching slope 211 is provided on the side of the driving part 21 opposite to the trigger end. The matching slope 211 can convert the up and down movement of the driving part 21 into a horizontal driving force for the transmission member 5. Specifically, as Figure 8 As shown, the unlocking position 14 is located below the locking position 13, and a matching slope 211 is provided on the lower side of the driving part 21, so that when the driving part 21 moves downward, the matching slope 211 matches with the trigger end of the transmission member 5 to drive the transmission member 5 to move horizontally. Similarly, a matching slope 211 is provided on the upper surface of the trigger end to improve the stability of contact with the driving part 21.

[0072] Embodiment 2: In this embodiment, the transmission member 5 has a connecting part rotatably connected to the pot cover 1, a first transmission part located on one side of the connecting part, and a second transmission part located on the other side of the connecting part. The first transmission part is used to cooperate with the driving part 21, and the second transmission part is used to drive the pressure conversion part 3. The transmission member 5 can rotate around the connecting part to drive the pressure conversion part 3.

[0073] In this embodiment, the transmission member 5 is a lever structure. When the user operates the operating handle 2 to cause the driving part 21 to trigger the first transmission part of the transmission member 5, the transmission member 5 as a whole rotates around the connection part, so that the second transmission part drives the pressure conversion member 3 to move. For example, in one embodiment, the unlocking position 14 is located below the locking position 13. The user presses the operating handle 2, so that the driving part 21 forms a downward pressure on the first transmission part, the second transmission part is lifted, and then the pressure conversion member 3 is lifted.

[0074] As a preferred embodiment of the present invention, Figure 3 , Figure 4 , Figure 6 , Figure 7 As shown, the limiting member 4 is located above or below the transmission member 5 , and when the driving part 21 cooperates with the transmission member 5 , the limiting member 4 and the driving part 21 are stopped to limit the driving part 21 to the unlocking position 14 .

[0075] When the driving part 21 switches to the unlocking position 14 and drives the transmission member 5, the limit member 4 forms a limit on the driving part 21 in the up and down directions, so that the driving part 21 remains in the unlocking position 14. Therefore, when the user operates the operating handle 2, once the operating handle 2 is pressed or pulled to make the driving part 21 enter the unlocking position 14 and cooperate with the transmission member 5, the application of up and down forces can be stopped, and only the operating handle 2 can be rotated without applying up and down forces to the operating handle 2 all the time, which makes the user's operation more labor-saving and improves the user experience.

[0076] For example, Figure 6 As shown, the unlocking position 14 is located below the locking position 13. When the driving part 21 cooperates with the transmission member 5, the limiting member 4 is located above the driving part 21, forming an upward limit thereon, so that the driving part 21 cannot float upward, and further the operating handle 2 cannot float upward.

[0077] Specifically, in one embodiment, Fig. 9 As shown, the pot cover 1 is provided with a mounting seat 9, a guide channel 15 for guiding the transmission member 5 is formed inside the mounting seat 9, and the mounting seat 9 has a limiting protrusion above the guide channel 15 to form a limiting member 4. Preferably, as Fig. 9 As shown, the mounting seat 9 is further provided with a guide opening 91 , and the pressure conversion member 3 passes through the guide opening 91 , so that the guide opening 91 forms a floating movement guide for the pressure conversion member 3 .

[0078] The utility model does not limit the resetting method of the operating handle 2. In one embodiment, the unlocking position 14 is located below the locking position 13, and an elastic reset member 8 is provided between the operating handle 2 and the pot cover 1. The elastic reset member 8 is used to apply an upward thrust to the operating handle 2 so that the driving part 21 switches from the unlocking position 14 to the locking position 13.

[0079] In this embodiment, the user needs to press the operating handle 2 to make the driving part 21 enter the unlocking position 14. When the user stops applying downward pressure, the elastic reset member 8 pushes the operating handle 2 upward to float and reset.

[0080] In another embodiment, the unlocking position 14 is located above the locking position 13, and no reset structure is required. The user needs to pull the operating handle 2 upward to make the driving part 21 enter the unlocking position 14. When the user stops applying the upward pulling force, the operating handle 2 falls under its own gravity, so that the driving part 21 returns to the locking position 13.

[0081] Preferably, in the present invention, the elastic member 7, the reset member 6 and the elastic reset member 8 are all springs to save costs. Of course, the three can also be other structures that can drive reset, such as silicone members, etc., which are not limited here.

[0082] It should be noted that the present invention does not limit the assembly method of the operating handle 2 and the driving part 21. In one embodiment, Figure 8 As shown, the operating handle 2 further includes a handle body 22 . The handle body 22 and the driving part 21 are an integrally formed structure, and the driving part 21 is located inside the pot cover 1 .

[0083] In this embodiment, the handle body 22 and the driving part 21 are integrally formed. The handle body 22 is located outside the pot cover 1, and the driving part 21 is located inside the pot cover 1. Therefore, the user can operate the handle body 22 regardless of whether it is driven up and down or rotated. The driving part 21 can move up and down and rotate with the handle body 22.

[0084] In another embodiment, the driving part 21 and the handle body 22 are separately formed structures, at least a part of the driving part 21 is located inside the pot cover 1, and the driving part 21 also has an operating end located outside the pot cover 1.

[0085] In this embodiment, the driving part 21 is separated from the handle body 22 and can move independently. The user can rotate the handle body 2 by operating it, and move the driving part 21 up and down by operating it. The two-step operation requires operating the two parts separately. This makes the movement trajectory of the driving part 21 and the handle body 22 more single, and improves reliability. Specifically, the operating end of the driving part 21 can be pressed first to make the driving part 21 enter the unlocking position 14, and then the handle body 22 can be rotated to drive the transmission member 5.

[0086] As a preferred embodiment, the pot cover 1 includes a cover body and a locking cover, and the operating handle 2 can rotate to drive the locking cover to rotate relative to the cover body, so that the pot cover 1 has a locked state locked with the pot body, and an unlocked state unlocked with the pot body.

[0087] When the user operates the operating handle 2 to rotate the pot cover 1, the position switching of the pressure conversion element 3 and the state switching of the pot cover 1 and the pot body can be realized synchronously. For example, in the initial state, the pressure conversion element 3 falls in the pressure-free mode, and the pot cover 1 and the pot body are in the unlocked state. When the user turns the operating handle 2, the pressure conversion element 3 is driven to float up and switch to the pressure mode. At the same time, the pot cover 1 and the pot body are locked, so that the locking of the pot cover 1 and the switching of the cooking mode of the cooking utensil are completed in one step, which simplifies the user's operation steps and improves the user experience.

[0088] In this embodiment, when the lock cover is rotated from the unlocked state to the locked state, the operating handle 2 also needs to move in the up and down directions first, so that the driving part 21 enters the unlocked position 14, and then the operating handle 2 can drive the lock cover to rotate. When rotating from the locked state to the unlocked state, there is no need to operate the operating handle 2 to move in the up and down directions, and the pot cover 1 can be rotated directly.

[0089] The parts not described in the present invention can be realized by adopting or drawing on the existing technology.

[0090] The various embodiments in this specification are described in a progressive manner, and the same or similar parts between the various embodiments can be referenced to each other, and each embodiment focuses on the differences from other embodiments.

[0091] The above description is only an embodiment of the present invention and is not intended to limit the present invention. For those skilled in the art, the present invention may have various modifications and variations. Any modification, equivalent substitution, improvement, etc. made within the spirit and principle of the present invention shall be included in the scope of the claims of the present invention.
