Description

Technical Field

[0001] The present application relates to the technical field of cooking appliances, in particular to an upper handle and a cooking container. Background Art

[0002] A pressure cooker includes a pot lid and a pot body. An upper handle and a pressure relief valve are provided on the pot lid, and a lower handle cooperating with the upper handle is provided on the pot body. Among them, a locking member is provided on the upper handle. When the pressure cooker is in the open lid state (i.e., the upper handle is separated from the lower handle), the locking member locks the pressure relief valve to prevent the pressure relief valve from automatically opening when the pot lid is inverted; when the pressure cooker is in the closed lid state (i.e., the upper handle cooperates with the lower handle), the locking member unlocks the pressure relief valve to enable the pressure relief valve to work properly during cooking. However, most of the existing locking members are of an integral structure. In order to enable the locking member to cooperate with the pressure relief valve, the upper handle and the lower handle at the same time to meet its functional requirements, it is necessary to make the locking member have a high machining accuracy, resulting in a large machining difficulty and a high production cost of the locking member. Summary of the Utility Model

[0003] In view of this, the present application provides an upper handle and a cooking container to solve the technical problem that the machining accuracy of the locking member in the prior art is relatively high, resulting in a large machining difficulty and a high production cost of the locking member.

[0004] The present application provides an upper handle for a cooking container. The upper handle includes a first handle body, a locking member, an operating member, and a connecting member. The locking member is movable relative to the first handle body. The operating member is movably connected to the first handle body. Two ends of the connecting member are respectively movably connected to the locking member and the operating member.

[0005] Wherein, during the movement of the operating member relative to the first handle body, the locking member can be driven to move through the connecting member, so that the upper handle is in a first state or a second state. In the first state, the upper handle is used to lock with the lower handle of the cooking container. In the second state, the upper handle is used to unlock with the lower handle of the cooking container.

[0006] In the embodiments of the present application, the user only needs to drive the operating member of the upper handle to move, so as to change the locked state or the unlocked state of the cooking container, which has the characteristics of being easy to implement. At the same time, the component composed of the locking member, the operating member and the connecting member being movably connected to each other can simplify the internal structure of the upper handle, which is beneficial to reducing the design difficulty and manufacturing difficulty of the upper handle. And separately machining the locking member, the operating member and the connecting member can reduce the overall production cost of the upper handle and improve the production efficiency. In addition, the separately arranged locking member, operating member and connecting member are also beneficial to the subsequent maintenance work of the upper handle, so that only the failed parts need to be replaced after it is damaged, thereby reducing the maintenance cost. In addition, the movably connected locking member, connecting member and operating member can also reduce the risk of jamming during the operation of the upper handle and improve the reliability and stability of the state switching of the upper handle.

[0007] In a possible implementation manner, two ends of the connecting member are respectively rotatably connected to the locking member and the operating member, and the operating member is rotatably connected to the first handle body.

[0008] In the embodiments of the present application, the upper handle further includes a rotating shaft and a mounting seat. The mounting seat is detachably connected to the first handle body, and the operating member is rotatably connected to the mounting seat through the rotating shaft to improve the stability and reliability of the installation of the operating member, make the rotation of the operating member smoother, and is beneficial to improving the reliability of the upper handle during operation. At the same time, the locking member, the operating member and the connecting member can form a linkage mechanism to convert the rotation of the operating member into the movement of the locking member along the first direction or the second direction, so as to further reduce the production cost while retaining the original functions of the upper handle. Wherein, the first direction is opposite to the second direction.

[0009] In a possible implementation manner, the operating member includes a connecting portion and a cooperating portion. The connecting portion is rotatably connected to the connecting member, and the cooperating portion is used for locking or unlocking with the lower handle of the cooking container.

[0010] In the embodiments of the present application, the lower handle has a sliding groove, which includes a limiting section and a guiding section that are connected and communicate with each other. The limiting section extends along the radial direction of the cooking container, and the guiding section extends along the circumferential direction of the cooking container. Along the extending direction of the guiding section, the side wall on at least one side of the guiding section is arc-shaped, so that the cross-sectional dimension of the guiding section near the limiting section is smaller than the cross-sectional dimension of the guiding section far from the limiting section. At the same time, at least one side wall of the guiding section is an arc surface structure. The snap-fit between the engaging portion and the sliding groove can realize the fitting connection between the upper handle and the lower handle, and the release of the snap-fit between the engaging portion and the sliding groove can realize the disconnection between the upper handle and the lower handle. And during the process of their fitting connection or disconnection, the arc-shaped guiding section can improve the reliability of the fitting, and the arc surface structure of the side wall of the guiding section can reduce the wear between the engaging portion, which is beneficial to improving the service life of the upper handle and the lower handle. At the same time, the way of the engaging portion engaging with the limiting section has the characteristics of simple structure and easy implementation.

[0011] In a possible implementation manner, the operating member further includes an operating portion, the operating portion is fixedly connected to the connecting portion and the engaging portion, and at least part of the structure of the operating portion extends out of the first handle body.

[0012] In the embodiments of the present application, one end of the operating portion extends out of the first handle body for the user to press, which is beneficial to improving the operating feel of the user. The other end of the operating portion is fixedly connected to the connecting portion and the engaging portion, so as to improve the structural stability of the operating member by means of fixed connection. Among them, the connecting portion, the engaging portion and the operating portion can be an integrated structure, that is, the operating member is integrally formed. This enables the connecting portion, the engaging portion and the operating portion to be assembled without the need for assembly, which is not only beneficial to reducing the weight of the operating member, but also can improve the overall structural performance of the operating member, so that it can have a long service life.

[0013] In a possible implementation manner, the first handle body has an opening, at least part of the structure of the operating portion extends out of the first handle body through the opening, and during the rotation of the operating member, the operating portion can abut against the side wall of the opening.

[0014] In the embodiments of the present application, when the operating portion abuts against the first side wall of the opening, the upper handle and the lower handle are disconnected, and the upper handle is in the second state, and the engaging portion is disengaged from the sliding groove; when the operating portion is in the middle area of the opening, the upper handle and the lower handle are fitted and connected, and the upper handle is in the first state, and the engaging portion abuts against the side wall of the limiting section; when the operating portion abuts against the second side wall of the opening, the upper handle is in the pressing state, and the engaging portion is disengaged from the limiting section and is located in the guiding section, so that the user can judge the working state of the upper handle according to the position of the operating portion, reducing the possibility of misoperation.

[0015] In a possible implementation, the upper handle further includes an elastic member, one end of the elastic member is elastically connected to one end of the locking member facing the connecting member, and the other end is elastically connected to the first handle body.

[0016] In the embodiment of the present application, both ends of the elastic member are elastically connected to the first handle body and the locking member respectively, so that the elastic member has a resilience during the process of opening and closing the lid, thereby being able to drive the locking member to reset, and further driving the upper handle to return to the second state.

[0017] When the cooking container is in the open-lid state, the upper handle is disengaged from the lower handle, the upper handle is in the second state, the operating portion abuts against the first side wall of the opening, the elastic member is in the initial state, and under the action of the elastic member, the link mechanism composed of the locking member, the connecting member and the operating member is in the unfolded state.

[0018] During the process of closing the lid of the cooking container, the container lid rotates in the fourth direction, the engaging portion cooperates with the sliding groove and moves in the guiding section towards the direction close to the limiting section. At the same time, the engaging portion moves in the first direction under the action of the side wall of the guiding section, so that the operating member rotates relative to the first handle body, thereby driving the connecting member and the locking member to move in the second direction through the connecting portion, and further causing the locking member to compress the elastic member with the first handle body.

[0019] Wherein, when the engaging portion moves into the limiting section, since the engaging portion disengages from the side wall of the guiding section, the elastic member releases the restoring force and drives the engaging portion to move in the second direction, so that the engaging portion abuts against the side wall of the limiting section to limit the movement of the limiting section along the circumferential direction of the cooking container, and further enables the upper handle and the lower handle to be cooperatively connected, and the cooking container is in the closed-lid state. And when the cooking container is in the closed-lid state, the elastic member is in the first compression state, and the connecting portion is located in the middle area of the opening.

[0020] During the process of opening the lid of the cooking container, the user applies an external force to the operating portion, so that the operating portion moves in the height direction of the cooking container towards the direction of the lower handle under the action of the external force, thereby driving the operating member to rotate relative to the first handle body, and driving the engaging portion to move in the first direction to move out of the limiting section and into the guiding section. At the same time, it also drives the connecting member and the locking member to move in the second direction, so that the locking member and the first handle body further compress the elastic member, so that the upper handle is in the pressed state. And when the upper handle is in the pressed state, the elastic member is in the second compression state, and the connecting portion abuts against the second side wall of the opening.

[0021] Among them, when the matching part moves into the guide section, the user can drive the container cover to rotate along the third direction, so that the matching part moves in the guide section toward the direction away from the limiting section, and when the external force is removed, the elastic member releases the restoring force, so that the operating member rotates relative to the first handle body, the matching part moves in the second direction and abuts against the side wall of the guide section, the connecting member and the locking member move in the first direction until the matching part disengages from the slide groove, so that the upper handle is disconnected from the lower handle, and the upper handle returns to the second state under the action of the elastic member.

[0022] The present application also provides a cooking container, which includes a container body, a container cover and an upper handle, wherein the container body is provided with a lower handle, the container cover is equipped with a non-opening valve, and the upper handle is installed on the container cover, wherein the upper handle is the upper handle described above.

[0023] In an embodiment of the present application, during the rotation of the container lid relative to the container body, the locking member can lock the stop valve so that the stop valve cannot move along the height direction of the cooking container, or the locking member can unlock the stop valve so that the stop valve can move along the height direction of the cooking container.

[0024] During the closing process, the container cover moves relative to the container body in the fourth direction, so that the upper handle is connected with the lower handle, the container cover is locked with the container body, and the upper handle unlocks the check valve. At this time, the check valve is in an unlocked state. When the pressure in the container body increases, the check valve can be driven to move upward along the height direction of the cooking container to limit the movement of the locking member, thereby limiting the movement of the operating member relative to the first handle body, and further preventing the user from opening the cooking container by driving the operating member, thereby improving the safety of the user during the cooking process.

[0025] After the cooking container is depressurized, the check valve moves downward along the height direction of the cooking container under the action of its own gravity to reset the check valve, thereby releasing the restriction on the movement of the locking member, and allowing the user to drive the operating member to open the cooking container.

[0026] During the process of opening the lid, the container lid moves along the third direction relative to the container body, so that the upper handle is disconnected from the lower handle, the container lid is unlocked from the container body, and the upper handle locks the check valve. At this time, the check valve is in a locked state. When the container lid is inverted, the check valve has a tendency to move downward along the height direction of the cooking container under the action of its own gravity (that is, when the container lid is placed upright, the check valve moves upward along the height direction of the cooking container). The restriction of the check valve movement by the locking member can avoid the risk that the check valve cannot be reset, resulting in the container lid and the container body being unable to be completely locked during the process of closing the lid, thereby reducing the possibility of safety hazards in the cooking container during the cooking process and improving the safety of users.

[0027] In a possible embodiment, the check valve includes a valve stem, the lower handle includes a second handle body, the second handle body is provided with a slide groove, the slide groove includes a limiting section, the operating member has a matching portion, and the matching portion is slidably matched with the slide groove; the locking member has a movable hole and a limiting hole that are connected; when the upper handle is in the first state, the matching portion is engaged with the limiting section, and the valve stem can move in the movable hole along the height direction of the cooking container; when the upper handle is in the second state, the matching portion is released from the limiting section, and the valve stem is engaged with the limiting hole.

[0028] In the embodiment of the present application, when the upper handle is in the first state, the mating portion is engaged with the limiting section, and the valve stem can move in the movable hole along the height direction of the cooking container. At this time, the valve stem is in an unlocked state. When the pressure in the container body increases, the valve stem can be driven to move upward along the height direction of the cooking container and cooperate with the movable hole of the locking member to limit the movement of the locking member in the first direction or the second direction, thereby limiting the rotation of the operating member relative to the first handle body, and thus preventing the user from opening the cooking container by driving the operating member, thereby improving the safety of the user during the cooking process.

[0029] After the cooking container is depressurized, the valve stem moves downward in the height direction of the cooking container under the action of its own gravity, so that the valve stem and the movable hole are released from engagement, thereby releasing the restriction on the movement of the locking member in the first direction or in the second direction, thereby enabling the user to drive the operating member to open the cooking container.

[0030] When the upper handle is in the second state, the engagement between the matching portion and the limiting section is released, and the valve stem is engaged with the limiting hole to limit the movement of the valve stem in the height direction of the cooking container. At this time, the valve stem is in a locked state. When the container cover is inverted, the valve stem has a tendency to move downward in the height direction of the cooking container under the action of its own gravity (that is, when the container cover is placed upright, the valve stem moves upward in the height direction of the cooking container). The restriction of the movement of the valve stem by the locking member can avoid the risk that the valve stem cannot be reset, resulting in the container cover and the container body being unable to be completely locked during the closing process, thereby reducing the possibility of safety hazards in the cooking container during the cooking process and improving the safety of users.

[0031] In a possible embodiment, the limiting hole includes a first limiting hole and a second limiting hole located on both sides of the movable hole, and the first limiting hole and the second limiting hole are both connected to the movable hole, and the second limiting hole is located on the side of the movable hole away from the connecting member; in the process of switching the upper handle from the first state to the second state, the operating member can drive the locking member to move in a first direction through the connecting member, so that the valve stem can cooperate with the second limiting hole, and the matching part and the limiting section can be released from the engagement, and in the process of rotating the container cover, the matching part can be driven to disengage the slide groove along the circumference of the cooking container, and the operating member can drive the locking member to move in the second direction through the connecting member, so that the valve stem can cooperate with the first limiting hole; the first direction is opposite to the second direction.

[0032] In the embodiment of the present application, by arranging the first limiting hole and the second limiting hole on both sides of the movable hole, the upper handle can unlock the stop valve when the matching part and the limiting section are engaged, and when the lid is open, the operating part is not easy to move to the middle area of ​​the opening, so that the movable hole is not easy to cooperate with the valve stem, which is beneficial to further reduce the possibility of the valve stem moving along the height direction of the cooking container and improve the safety of the user during the cooking process.

[0033] In a possible implementation manner, a diameter of the movable hole is larger than a diameter of the first limiting hole, and larger than a diameter of the second limiting hole.

[0034] In the embodiment of the present application, when the pressure in the container body increases, the valve stem is driven to move upward along the height direction of the cooking container and cooperate with the movable hole of the locking member. At this time, since the diameters of the first limiting hole and the second limiting hole are both smaller than the diameter of the movable hole, the diameter of the valve stem in the ascending state is also larger than the diameters of the first limiting hole and the second limiting hole, so that the valve stem cannot move in the first direction or the second direction, thereby limiting the movement of the locking member in the first direction or the second direction, so that the user cannot open the cooking container by driving the operating member when the valve stem is in the ascending state, which is conducive to improving the safety of the user during the cooking process.

[0071] The accompanying drawings here are incorporated into the specification and form a part of this specification, showing embodiments in line with this application, and are used together with the specification to explain the principles of this application. Detailed implementation manners

[0072] For a better understanding of the technical solutions of this application, the embodiments of this application will be described in detail below with reference to the accompanying drawings.

[0073] It should be clear that the described embodiments are only a part of the embodiments of this application, rather than all of the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments in this application without creative efforts belong to the scope protected by this application.

[0074] The terms used in the embodiments of this application are only for the purpose of describing specific embodiments and are not intended to limit this application. The singular forms of "a", "the" and "said" used in the embodiments of this application and the appended claims are also intended to include the plural forms unless the context clearly indicates otherwise.

[0075] It should be understood that the term " / and / " used herein is only a description of the associated relationship of associated objects, indicating that three relationships may exist. For example, A and / or B may mean: A exists alone, A and B exist simultaneously, and B exists alone. In addition, the character " / " herein generally represents an "or" relationship between the associated objects before and after.

[0076] Embodiments of the present application provide an upper handle for a cooking container, such as Figure 1 , Figure 2 and Figure 3 shown. The cooking container includes a container lid 3 and a container body 4. The container lid 3 is provided with an upper handle 1, and the container body 4 is provided with a lower handle 2. During the rotation of the container lid 3 relative to the container body 4, the upper handle 1 and the lower handle 2 can be cooperatively connected to close the cooking container, enabling the user to start cooking or store it. Alternatively, the upper handle 1 and the lower handle 2 can be disconnected to open the cooking container, enabling the user to process the ingredients or clean it.

[0077] Specifically, the upper handle 1 includes a first handle body 11, a locking member 12, an operating member 13, and a connecting member 14. The locking member 12 is capable of moving relative to the first handle body 11. The operating member 13 is movably connected to the first handle body 11, and both ends of the connecting member 14 are movably connected to the locking member 12 and the operating member 13 respectively. Among them, the user can drive the operating member 13 to move relative to the first handle body 11 so as to control the connection relationship between the upper handle 1 and the lower handle 2 through the operating member 13.

[0078] During the movement of the operating member 13 relative to the first handle body 11, since both ends of the connecting member 14 are movably connected to the locking member 12 and the operating member 13 respectively, the operating member 13 can drive the connecting member 14 to move, and then drive the locking member 12 to move through the connecting member 14, so that the upper handle 1 can be switched between a first state and a second state to realize the change of the connection relationship between the upper handle 1 and the lower handle 2. When the user controls the operating member 13 to move relative to the first handle body 11 until the upper handle 1 is in the first state, the upper handle 1 is used to lock with the lower handle 2 of the cooking container. At this time, the upper handle 1 and the lower handle 2 are cooperatively connected, and the container lid 3 and the container body 4 are locked to close the cooking container. When the user controls the operating member 13 to move relative to the first handle body 11 until the upper handle 1 is in the second state, the upper handle 1 is used to unlock with the lower handle 2 of the cooking container. At this time, the upper handle 1 and the lower handle 2 are disconnected, and the container lid 3 and the container body 4 are unlocked to open the cooking container.

[0079] Therefore, in this embodiment, the user only needs to drive the operating member 13 of the upper handle 1 to change the locked state or unlocked state of the cooking container, which is easy to implement. At the same time, the components composed of the movable connection between the locking member 12, the operating member 13 and the connecting member 14 can simplify the internal structure of the upper handle 1, which is conducive to reducing the design difficulty and manufacturing difficulty of the upper handle 1, and the separate processing of the locking member 12, the operating member 13 and the connecting member 14 can reduce the overall production cost of the upper handle 1 and improve production efficiency. In addition, the separately arranged locking member 12, the operating member 13 and the connecting member 14 are also conducive to the subsequent maintenance of the upper handle 1, so that only the failed parts need to be replaced after it is damaged, thereby reducing the maintenance cost. In addition, the movable connection of the locking member 12, the connecting member 14 and the operating member 13 can also reduce the risk of the upper handle 1 getting stuck during operation, and improve the reliability and stability of the state switching of the upper handle 1.

[0080] In a specific embodiment, Figure 1 , Figure 5 , Figure 6 and Figure 7 As shown, the container cover 3 is also equipped with a check valve 31, which is cooperated with the locking piece 12 of the upper handle 1. When the container cover 3 rotates relative to the container body 4, the locking piece 12 can lock the check valve 31 so that the check valve 31 cannot move along the height direction of the cooking container, or the locking piece 12 can unlock the check valve 31 so that the check valve 31 can move along the height direction of the cooking container.

[0081] During the closing process, the container cover 3 moves along the fourth direction relative to the container body 4 , so that the upper handle 1 is connected with the lower handle 2 , the container cover 3 is locked with the container body 4 , and the upper handle 1 unlocks the check valve 31 .

[0082] At this time, the check valve 31 is in an unlocked state. When the pressure in the container body 4 increases, the check valve 31 can be driven to move upward along the height direction of the cooking container to limit the movement of the locking member 12, thereby limiting the movement of the operating member 13 relative to the first handle body 11, and further preventing the user from opening the cooking container by driving the operating member 13, thereby improving the safety of the user during the cooking process.

[0083] After the cooking container is depressurized, the check valve 31 moves downward along the height direction of the cooking container under the action of its own gravity to reset the check valve 31, thereby releasing the restriction on the movement of the locking member 12, and allowing the user to drive the operating member 13 to open the cooking container.

[0084] During the opening process, the container cover 3 moves along the third direction relative to the container body 4 , so that the upper handle 1 is disconnected from the lower handle 2 , the container cover 3 is unlocked from the container body 4 , and the upper handle 1 locks the check valve 31 .

[0085] At this time, the opening prevention valve 31 is in a locked state. When the container cover 3 is inverted, the opening prevention valve 31 has a tendency to move downward along the height direction of the cooking container (that is, when the container cover 3 is placed upright, the opening prevention valve 31 moves upward along the height direction of the cooking container) under the action of its own gravity. The restriction of the movement of the opening prevention valve 31 by the locking member 12 can avoid the risk that the opening prevention valve 31 cannot be reset, resulting in the container cover 3 and the container body 4 not being fully locked during the lid closing process, thereby reducing the possibility of potential safety hazards during the cooking process of the cooking container and improving the safety of the user.

[0086] In a specific embodiment, as Figure 2 and Figure 3 shown, both ends of the connecting member 14 are respectively rotatably connected to the locking member 12 and the operating member 13, and the operating member 13 is rotatably connected to the first handle body 11, so that the user can drive the operating member 13 to rotate relative to the first handle body 11, thereby driving the locking member 12 to move through the connecting member 14 to lock or unlock the opening prevention valve 31.

[0087] In the embodiment of the present application, the upper handle 1 further includes a rotating shaft 16 and a mounting seat 17. The mounting seat 17 is detachably connected to the first handle body 11, and the operating member 13 is rotatably connected to the mounting seat 17 through the rotating shaft 16 to improve the stability and reliability of the installation of the operating member 13, making the rotation of the operating member 13 smoother and conducive to improving the reliability of the upper handle 1 during the working process. At the same time, a link mechanism can be formed among the locking member 12, the operating member 13, and the connecting member 14 to convert the rotation of the operating member 13 into the movement of the locking member 12 in the first direction or the second direction, thereby further reducing the production cost while retaining the original functions of the upper handle 1. Among them, the first direction is opposite to the second direction.

[0088] In a specific embodiment, as Figure 4 、 Figure 5 and Figure 9 shown, the operating member 13 includes a connecting portion 131 and a mating portion 132. The connecting portion 131 is rotatably connected to the connecting member 14, and the mating portion 132 is used to lock or unlock with the lower handle 2 of the cooking container.

[0089] In the embodiment of the present application, the upper handle 1 and the lower handle 2 are distributed along the height direction of the cooking container. Among them, the mounting seat 17 has a through hole, and the mating portion 132 of the operating member 13 can extend out of the first handle body 11 through the through hole. The lower handle 2 has a chute 211, and the chute 211 includes a connected limiting section 211a and a guiding section 211b.

[0090] As Figure 4As shown, the limiting section 211a extends radially along the cooking container, and the guiding section 211b extends circumferentially along the cooking container. Along the extending direction of the guiding section 211b, the side wall on at least one side of the guiding section 211b is arc-shaped, so that the cross-sectional dimension of the guiding section 211b near the limiting section 211a is smaller than the cross-sectional dimension of the guiding section 211b far from the limiting section 211a.

[0091] Specifically, one end of the guiding section 211b far from the limiting section 211a is the inlet and outlet of the sliding groove 211. The inlet and outlet with a larger cross-sectional dimension is convenient for cooperating with the cooperating part 132 and guiding the cooperating part 132 to slide into the sliding groove 211, so that the fitting connection between the upper handle 1 and the lower handle 2 can be more easily realized.

[0092] More specifically, at least one side wall of the guiding section 211b is an arc surface structure, which is beneficial to reducing the wear between the cooperating part 132 and the sliding groove 211 during the cooperation process, thereby increasing the service life of the upper handle 1 and the lower handle 2.

[0093] Therefore, in this embodiment, the snap-fit between the cooperating part 132 and the sliding groove 211 can realize the fitting connection between the upper handle 1 and the lower handle 2, and the release of the snap-fit between the cooperating part 132 and the sliding groove 211 can realize the disconnection between the upper handle 1 and the lower handle 2. During the process of their fitting connection or disconnection, the arc-shaped guiding section 211b can improve the reliability of the cooperation, and the side wall of the guiding section 211b with an arc surface structure can reduce the wear between the cooperating part 132, which is beneficial to increasing the service life of the upper handle 1 and the lower handle 2. At the same time, the way of the cooperating part 132 being snap-connected to the limiting section 211a has the characteristics of simple structure and easy implementation.

[0094] In a specific embodiment, as Figure 6 and Figure 7 shown, the operating member 13 further includes an operating portion 133. The operating portion 133 is fixedly connected to the connecting portion 131 and the cooperating portion 132, and at least part of the structure of the operating portion 133 extends out of the first handle body 11.

[0095] In the embodiment of the present application, one end of the operating portion 133 extends out of the first handle body 11 for the user to press, which is beneficial to improving the operating feel of the user. The other end of the operating portion 133 is fixedly connected to the connecting portion 131 and the cooperating portion 132, so as to improve the structural stability of the operating member 13 by means of fixed connection. Among them, the connecting portion 131, the cooperating portion 132 and the operating portion 133 can be an integrated structure, that is, the operating member 13 is integrally formed. This makes it unnecessary to assemble between the connecting portion 131, the cooperating portion 132 and the operating portion 133, which is not only beneficial to reducing the weight of the operating member 13, but also can improve the overall structural performance of the operating member 13, enabling it to have a long service life.

[0096] In a specific embodiment, as Figure 5 , Figure 6 , Figure 8 and Figure 9 shown, the first handle body 11 has an opening 111, at least part of the structure of the operating portion 133 extends out of the first handle body 11 through the opening 111, and during the rotation of the operating member 13, the operating portion 133 can abut against the side wall of the opening 111.

[0097] In the embodiment of the present application, the opening 111 of the first handle body 11 extends along the height direction of the cooking container. Along the extending direction of the opening 111, the opening 111 includes a first side wall and a second side wall, and the second side wall is located on the side of the opening 111 close to the lower handle 2.

[0098] When the cooking container is in the closed lid state, the upper handle 1 and the lower handle 2 are cooperatively connected. The operating portion 133 is located in the middle area of the opening 111, and the engaging portion 132 is located in the limiting section 211a and abuts against its side wall to limit the circumferential movement of the engaging portion 132 along the cooking container. At this time, the upper handle 1 is in the first state.

[0099] During the process of the cooking container being switched from the closed lid state to the open lid state, the user applies an external force to the operating portion 133, so that the operating portion 133 moves towards the second side wall of the opening 111 under the action of the external force, thereby driving the operating member 13 to rotate relative to the first handle body 11, and driving the engaging portion 132 to move in the first direction to move out of the limiting section 211a and move into the guiding section 211b. At this time, the upper handle 1 is in the pressing state. And when the upper handle 1 is in the pressing state, the user can drive the container lid 3 to rotate in the third direction, so that the engaging portion 132 can slide out of the sliding groove 211 along the side wall of the guiding section 211b, and the upper handle 1 and the lower handle 2 are disengaged to unlock the cooking container. At the same time, during the process of the engaging portion 132 sliding along the side wall of the guiding section 211b, the engaging portion 132 can also move in the second direction, so that after the engaging portion 132 completely disengages from the sliding groove 211, the operating portion 133 can abut against the first side wall of the opening 111. At this time, the upper handle 1 is in the second state.

[0100] Therefore, in this embodiment, when the operating portion 133 abuts against the first side wall of the opening 111, the upper handle 1 and the lower handle 2 are disengaged, the upper handle 1 is in the second state, and the engaging portion 132 disengages from the sliding groove 211; when the operating portion 133 is in the middle area of the opening 111, the upper handle 1 and the lower handle 2 are cooperatively connected, the upper handle 1 is in the first state, and the engaging portion 132 abuts against the side wall of the limiting section 211a; when the operating portion 133 abuts against the second side wall of the opening 111, the upper handle 1 is in the pressing state, the engaging portion 132 disengages from the limiting section 211a and is located in the guiding section 211b, so that the user can judge the working state of the upper handle 1 according to the position of the operating portion 133, reducing the possibility of misoperation.

[0101] In a specific embodiment, as Figure 3 , Figure 5 , Figure 8 and Figure 9 shown, the upper handle 1 further includes an elastic member 15. One end of the elastic member 15 is elastically connected to one end of the locking member 12 facing the connecting member 14, and the other end is elastically connected to the first handle body 11.

[0102] In the embodiment of the present application, both ends of the elastic member 15 are elastically connected to the first handle body 11 and the locking member 12 respectively, so that the elastic member 15 has a resilience force during the process of opening and closing the lid, thereby being able to drive the locking member 12 to reset, and further driving the upper handle 1 to return to the second state.

[0103] When the cooking container is in the open lid state, the upper handle 1 is disconnected from the lower handle 2, the upper handle 1 is in the second state, the operating portion 133 abuts against the first side wall of the opening 111, the elastic member 15 is in the initial state, and under the action of the elastic member 15, the link mechanism composed of the locking member 12, the connecting member 14 and the operating member 13 is in the unfolded state.

[0104] During the process of closing the lid of the cooking container, the container lid 3 rotates in the fourth direction, the engaging portion 132 cooperates with the sliding groove 211 and moves in the guiding section 211b towards the direction close to the limiting section 211a. At the same time, the engaging portion 132 moves in the first direction under the action of the side wall of the guiding section 211b, so that the operating member 13 rotates relative to the first handle body 11, thereby driving the connecting member 14 and the locking member 12 to move in the second direction through the connecting portion 131, and further causing the locking member 12 to compress the elastic member 15 with the first handle body 11.

[0105] Wherein, when the engaging portion 132 moves into the limiting section 211a, since the engaging portion 132 disengages from the side wall of the guiding section 211b, the elastic member 15 releases the restoring force and drives the engaging portion 132 to move in the second direction, so that the engaging portion 132 abuts against the side wall of the limiting section 211a to limit the movement of the limiting section 211a along the circumferential direction of the cooking container, and further enables the upper handle 1 to be cooperatively connected with the lower handle 2, and the cooking container is in the closed lid state. And when the cooking container is in the closed lid state, the elastic member 15 is in the first compressed state, and the connecting portion 131 is located in the middle area of the opening 111.

[0106] During the process of opening the cooking container lid, the user applies an external force to the operating part 133, causing the operating part 133 to move in the height direction of the cooking container towards the lower handle 2 under the action of the external force. As a result, the operating member 13 rotates relative to the first handle body 11, and drives the engaging part 132 to move in the first direction, so as to move out of the limiting section 211a and move into the guiding section 211b. At the same time, it also drives the connecting member 14 and the locking member 12 to move in the second direction, thereby further compressing the elastic member 15 between the locking member 12 and the first handle body 11, so that the upper handle 1 is in a pressed state. And when the upper handle 1 is in the pressed state, the elastic member 15 is in the second compressed state, and the connecting part 131 abuts against the second side wall of the opening 111.

[0107] Wherein, after the engaging part 132 moves into the guiding section 211b, the user can drive the container lid 3 to rotate in the third direction, so that the engaging part 132 moves in the guiding section 211b in a direction away from the limiting section 211a. And when the external force is removed, the elastic member 15 releases the restoring force, causing the operating member 13 to rotate relative to the first handle body 11, the engaging part 132 to move in the second direction and abut against the side wall of the guiding section 211b, and the connecting member 14 and the locking member 12 to move in the first direction until the engaging part 132 disengages from the sliding groove 211, so as to disconnect the upper handle 1 from the lower handle 2, and the upper handle 1 returns to the second state under the action of the elastic member 15.

[0108] In a specific embodiment, as Figure 3 , Figure 5 , Figure 8 and Figure 9 shown, the anti-opening valve 31 includes a valve stem 311, the lower handle 2 includes a second handle body 21, the second handle body 21 is provided with the above-mentioned sliding groove 211, and the locking member 12 further has a communicating moving hole 121 and a limiting hole.

[0109] When the upper handle 1 is in the first state, the engaging part 132 is snap-fitted with the limiting section 211a, and the valve stem 311 can move in the moving hole 121 along the height direction of the cooking container. At this time, the valve stem 311 is in the unlocked state. When the pressure in the container body 4 increases, it can drive the valve stem 311 to move upward along the height direction of the cooking container and cooperate with the moving hole 121 of the locking member 12 to limit the movement of the locking member 12 in the first direction or the second direction, thereby restricting the rotation of the operating member 13 relative to the first handle body 11, and further preventing the user from opening the cooking container by driving the operating member 13, improving the safety of the user during the cooking process.

[0110] After the cooking container is depressurized, the valve stem 311 moves downward in the height direction of the cooking container under the action of its own gravity, so that the valve stem 311 is released from the movable hole 121, thereby releasing the restriction on the movement of the locking member 12 in the first direction or in the second direction, and allowing the user to drive the operating member 13 to open the cooking container.

[0111] When the upper handle 1 is in the second state, the engagement portion 132 is released from the limiting section 211a, and the valve stem 311 is engaged with the limiting hole to limit the movement of the valve stem 311 in the height direction of the cooking container. At this time, the valve stem 311 is in a locked state. When the container cover 3 is inverted, the valve stem 311 has a tendency to move downward in the height direction of the cooking container under the action of its own gravity (that is, when the container cover 3 is placed upright, the valve stem 311 moves upward in the height direction of the cooking container). The restriction of the movement of the valve stem 311 by the locking member 12 can avoid the risk that the valve stem 311 cannot be reset, resulting in the container cover 3 and the container body 4 being unable to be completely locked during the closing process, thereby reducing the possibility of safety hazards in the cooking container during the cooking process and improving the safety of users.

[0112] In a specific embodiment, Figure 3 , Figure 5 , Figure 8 and Figure 9 As shown, the limiting holes include a first limiting hole 122 and a second limiting hole 123 located on both sides of the movable hole 121 , and the first limiting hole 122 and the second limiting hole 123 are both connected to the movable hole 121 , and the second limiting hole 123 is located on the side of the movable hole 121 away from the connecting member 14 .

[0113] When the upper handle 1 switches from the first state to the second state, the operating member 13 drives the locking member 12 to move in the second direction, so that the valve stem 311 can cooperate with the second limiting hole 123 and the matching portion 132 is released from the limiting section 211a.

[0114] Specifically, the user applies an external force to the operating part 133 so that the operating part 133 moves along the height direction of the cooking container toward the lower handle 2 under the action of the external force, thereby driving the operating member 13 to rotate relative to the first handle body 11, and driving the matching part 132 to move along the first direction to move out of the limiting section 211a and into the guide section 211b. At the same time, it also drives the connecting member 14 and the locking member 12 to move along the second direction, thereby making the locking member 12 move along the second direction relative to the valve stem 311, so that the second limiting hole 123 cooperates with the valve stem 311, and then the upper handle 1 locks the stop valve 31 in the pressed state.

[0115] During the rotation of the container lid 3, the engaging portion 132 can be driven to disengage from the sliding groove 211 along the circumferential direction of the cooking container, so as to drive the locking member 12 to move in the first direction, enabling the valve stem 311 to cooperate with the first limiting hole 122.

[0116] Specifically, after the engaging portion 132 moves into the guiding section 211b, the user can drive the container lid 3 to rotate in the third direction, causing the engaging portion 132 to move away from the limiting section 211a within the guiding section 211b. When the external force is removed, the elastic member 15 releases the restoring force, causing the operating member 13 to rotate relative to the first handle body 11. The engaging portion 132 moves in the second direction and abuts against the side wall of the guiding section 211b, and the connecting member 14 and the locking member 12 move in the first direction. As a result, the locking member 12 moves relative to the valve stem 311 in the first direction, enabling the first limiting hole 122 to cooperate with the valve stem 311, and further enabling the upper handle 1 to lock the non-return valve 31 in the second state.

[0117] Therefore, in this embodiment, by providing the first limiting hole 122 and the second limiting hole 123 on both sides of the movable hole 121, the upper handle 1 can unlock the non-return valve 31 when the engaging portion 132 is engaged with the limiting section 211a. Moreover, in the open lid state, the operating portion 133 is not easily moved to the middle area of the opening 111, so that the movable hole 121 is not easily engaged with the valve stem 311, which is beneficial to further reducing the possibility of the valve stem 311 moving in the height direction of the cooking container and improving the safety of the user during the cooking process.

[0118] In a specific embodiment, as Figure 3 shown, the diameter of the movable hole 121 is larger than the diameter of the first limiting hole 122 and larger than the diameter of the second limiting hole 123, so that the valve stem 311 can only move in the height direction of the cooking container within the movable hole 121.

[0119] Specifically, when the pressure inside the container body 4 increases, it drives the valve stem 311 to move upward in the height direction of the cooking container and cooperate with the movable hole 121 of the locking member 12. At this time, since the diameters of both the first limiting hole 122 and the second limiting hole 123 are smaller than the diameter of the movable hole 121, the diameter of the valve stem 311 in the rising state is also larger than the diameters of the first limiting hole 122 and the second limiting hole 123. As a result, the valve stem 311 cannot move in the first direction or the second direction, thereby restricting the movement of the locking member 12 in the first direction or the second direction, and preventing the user from opening the cooking container by driving the operating member 13 when the valve stem 311 is in the rising state, which is beneficial to improving the safety of the user during the cooking process.
