[0035] See also Figures 1 to 8 As shown, according to an embodiment of the present invention, a cooking utensil is provided, and the cooking utensil in this embodiment is particularly a pressure cooker.

[0036] Specifically, the cooking utensil in this embodiment includes a pot cover assembly and a pot body assembly, wherein the pot body assembly is provided with an inner pot 60, which is detachably installed in the pot body assembly, and the pot cover assembly is provided on the pot body assembly to seal the inner pot 60 on the pot body assembly, so as to improve the cooking efficiency of the cooking utensil in this embodiment.

[0037] The pot cover assembly in this embodiment includes a pot cover body 10, a switching assembly 30, and a pressure relief assembly (not shown in the figure).

[0038] The pot cover body 10 is provided with an inner cover assembly 11 and an upper cover seat 13, the inner cover assembly 11 is provided with an exhaust hole 111, the upper cover seat 13 is located above the inner cover assembly 11, the inner cover assembly 11 is provided with an exhaust hole 111, and the upper cover seat 13 is provided with a limiting hole 132 corresponding to the exhaust hole 111; the switching assembly 30 is installed on the pot cover body 10, the switching assembly 30 includes a movable shaft 32 and a sealing gasket 34, the sealing gasket 34 is arranged at the bottom end of the movable shaft 32, and the movable shaft 32 can be lifted and installed in the limiting hole 132 to open the exhaust hole 111 and be in a non-pressurized working state (see 3 to Figure 5 As shown) or close the exhaust hole 111 and put it in a pressurized working state (see Figures 6 to 8 The pressure relief assembly is mounted on the pot cover body 10 to facilitate pressure relief of the inner pot 90.

[0039] During actual operation, the switching assembly 30 is driven to rise and fall through other structures, and the movable shaft 32 rises and falls in the limiting hole 132, thereby driving the sealing gasket 34 to open or close the exhaust hole, so that the pot cover assembly in the present invention can be switched between a pressurized working state and a non-pressurized working state, which can be suitable for the cooking needs of various ingredients, has a simple structure, and can reduce the production cost of the pot cover assembly.

[0040] The pot cover assembly also includes a handle assembly 20 and an operating link 40. The handle assembly 20 is rotatably mounted on the pot cover body 10. The operating link 40 is connected to the handle assembly 20, and the operating link 40 rotates with the handle assembly 20 to switch the switching assembly 30 between a non-pressurized working state and a pressurized working state.

[0041] When the pot cover assembly in this embodiment is used specifically, the pot cover assembly is first placed on the pot body assembly. When the inner pot 60 on the pot body assembly needs to be sealed, the handle assembly 20 is rotated to directly drive the operating link 40 to rotate, thereby causing the switching assembly 30 to seal the exhaust hole 111 and put it in a pressurized working state, which is convenient for sealing the inner pot 60 and improving the cooking efficiency of the cooking appliance. When the food cooked in the pressure cooker does not require high-pressure cooking, the handle assembly 20 can be rotated to drive the operating link 40 to rotate, thereby driving the lifting and lowering member to cause the switching assembly 30 to open the exhaust hole 111 and put it in a non-pressurized working state. At this time, the airflow in the inner pot 60 can be discharged from the exhaust hole 111, and the pressure cooker is in a non-pressurized working state, which is convenient for meeting the cooking needs of different food ingredients.

[0042] Preferably, the operating link 40 in the present embodiment is directly rigidly connected to the handle assembly 20. Since the operating link 40 in the present embodiment is directly rigidly connected to the handle assembly 20, when the handle assembly 20 is actually rotated, the operating link 40 can be directly driven to drive the switching assembly 30 to move. The connection between the mechanisms is relatively simpler and the transmission accuracy is higher, which can improve the assembly efficiency of the pot cover assembly in the present embodiment and improve the production efficiency of the pot cover assembly.

[0043] Combination Figure 2 and Figure 3 As shown, a mounting hole 42 is provided on the operating link 40 in this embodiment, and the handle assembly 20 includes a rotating handle 21. During actual installation, the rotating shaft of the rotating handle 21 is inserted into the mounting hole 42, and the operating link 40 and the rotating handle 21 are directly rigidly connected by screws or pins or rivets or welding. The structure is simple and reliable, and can effectively improve the transmission accuracy and assembly efficiency of the operating link 40 in this embodiment.

[0044] Of course, in other embodiments of the present invention, the mounting hole 42 may not be provided on the operating link 40, and the operating link 40 and the handle assembly 20 may be directly fixed together by screws, pins, rivets or welding. As long as it is other deformation methods based on the concept of the present invention, it is within the protection scope of the present invention.

[0045] See again Figures 1 to 8 As shown, the pot cover body 10 in this embodiment also includes a snap-on cover 12. When actually installed, the snap-on cover 12 is rotatably covered on the inner cover assembly 11, and the edge of the snap-on cover 12 has a snap-on protrusion for snapping with the inner pot 60. The operating link 40 is located above the upper cover plate seat 13 and is fixedly connected to the snap-on cover 12. When the handle assembly 20 is rotated and the pot cover assembly is in a non-pressurized working state, the snap-on cover 12 rotates with the operating link 40. At this time, the snap-on portion of the snap-on cover 12 is separated from the inner pot 60 (see Figure 5As shown in FIG. 1 , when the handle assembly 20 is rotated to put the pot cover assembly in a pressurized working state, the buckle cover 12 rotates together with the operating connecting rod 40. At this time, the buckle part of the buckle cover 12 and the inner pot 60 are matched and sealed (see FIG. 1 ). Figure 8 As shown), it is convenient to seal the inner pot 60.

[0046] During actual installation, a clearance hole 131 is provided on the upper cover plate seat 13 , and the snap-fit ​​cover 12 and the operating connecting rod 40 are positioned by a positioning assembly passing through the clearance hole 131 , so as to drive the snap-fit ​​cover 12 to rotate.

[0047] Preferably, the positioning assembly in this embodiment includes a matching positioning pin 121 and a positioning hole 41, one of which is arranged on the operating link 40, and the other is arranged on the snap-on cover 12. In this embodiment, the positioning pin 121 is arranged on the snap-on cover 12, and the positioning hole 41 is correspondingly arranged on the operating link 40. When the handle assembly 20 is rotated, the operating link 40 rotates with the handle assembly 20, thereby driving the positioning pin 121 and the snap-on cover 12 to rotate. The structure is simple, stable and reliable. In order to prevent interference, in this embodiment, the clearance hole 131 is arranged as an arc-shaped long strip hole, so as to provide clearance space for the rotation of the positioning pin 121 and the snap-on cover 12.

[0048] In other embodiments of the present invention, the positioning assembly may also be configured as a positioning pin or a positioning bolt or other structures. As long as it is other deformation methods based on the concept of the present invention, it is within the protection scope of the present invention.

[0049] In order to facilitate the switching of the switching assembly 30 between the non-pressurized working state and the pressurized working state, a wedge-shaped surface 43 is provided on the operating link 40 in this embodiment, and the operating link 40 is arranged on the upper cover plate seat 13 horizontally or at a certain angle. During the rotation of the operating link 40, the wedge-shaped surface 43 contacts the switching assembly 30 and causes the switching assembly 30 to move up and down so that the switching assembly 30 switches between the pressurized working state and the non-pressurized working state. In actual operation, the operating link 40 rotates with the handle assembly 20, and the wedge-shaped surface 43 on the operating link 40 is inserted into the switching assembly 30. The reciprocating rotation of the operating link 40 drives the switching assembly 30 to move up and down to switch between the pressurized working state and the non-pressurized working state.

[0050] The snap-fit ​​cover 12 in this embodiment is provided with a hollow portion 122. The hollow portion 122 is provided to provide necessary clearance space for the installation of the switching assembly 30. Correspondingly, the upper cover plate seat 13 is provided with a limiting hole 132 located above the hollow portion 122 and the exhaust hole 111.

[0051] The switching assembly 30 further includes a first sealing ring 31 and an elastic element 33 .

[0052] During installation, the bottom end of the first sealing ring 31 is arranged around the outer periphery of the top of the exhaust hole 111, and the top end of the first sealing ring 31 is arranged around the outer periphery of the bottom of the limiting hole 132. Through the action of the first sealing ring 31, the gap above the exhaust hole 111 and between the inner cover assembly 11 and the upper cover seat 13 can be sealed; the bottom end of the movable shaft 32 has an outer flange 321, and the movable shaft 32 is drivingly connected to the wedge surface 43; the elastic element 33 is sleeved on the outer periphery of the movable shaft 32, and the two ends of the elastic element 33 are respectively pressed against the outer flange 321 and the upper cover seat 13.

[0053] Preferably, the elastic element 33 in this embodiment is a spring. Of course, in other embodiments of the present invention, the elastic element 33 can also be set as an elastic rubber sleeve or other structures. As long as it is other deformation methods under the conception of the present invention, it is within the protection scope of the present invention.

[0054] See also Figures 3 to 7 As shown, when the operating link 40 rotates counterclockwise with the handle assembly 20, the wedge surface 43 lifts the movable shaft 32, thereby driving the sealing gasket 34 to lift upward to open the exhaust hole 111. At this time, the airflow in the inner pot 60 can be discharged upward from the exhaust hole 111, and the pot cover assembly is in a non-pressurized working state. When the operating link 40 rotates clockwise with the handle assembly 20, the wedge surface 43 moves away from the movable shaft 32, and the movable shaft 32 moves downward under the action of the elastic element 33, thereby driving the sealing gasket 34 to move downward to seal the exhaust hole 111. At this time, the airflow in the inner pot 60 cannot be discharged upward from the exhaust hole 111, and the pot cover assembly is in a pressurized working state.

[0055] In order to effectively improve the driving stability of the operating link 40 on the switching assembly 30 in this embodiment, a slot 44 is provided on the wedge surface 43 in this embodiment, and the lifting and lifting member is a lifting and lifting plate 35, which is fixedly connected to the movable shaft 32 by screws 50, and the lifting and lifting plate 35 is located above the limiting hole 132, and the movable shaft 32 is located in the slot 44. The lifting and lifting plate 35 is set on the wedge surface 43, so that it is easy to rise and fall with the wedge surface 43 to drive the movable shaft 32 to rise and fall, and the structure is stable and reliable. The end of the lifting and lifting plate 35 in this embodiment is provided with a protruding block protruding toward one end of the movable shaft 32, and the protruding block is set on the wedge surface 43, which can prevent the wedge surface 43 and the lifting and lifting plate 35 from getting stuck, thereby ensuring the smooth movement of the operating link 40.

[0056] The switching assembly 30 further includes a second sealing ring 36 which is sleeved on the outer periphery of the movable shaft 32 to seal the gap between the movable shaft 32 and the limiting hole 132 to prevent the airflow in the exhaust hole 111 from being discharged from the gap between the movable shaft 32 and the limiting hole 132 .

[0057] See again Figures 1 to 8 As shown, the upper cover plate seat 13 in this embodiment is provided with a guide groove 133 and a pressure relief exhaust bin 134, the first end of the guide groove 133 extends to the bottom end of the limiting hole 132, and the second end of the guide groove 133 extends to the pressure relief exhaust bin 134, and the pressure relief assembly is installed in the pressure relief exhaust bin 134, so that the airflow discharged from the exhaust hole 111 can be discharged from the pressure relief exhaust bin 134, and the structure is simple, which is convenient for ensuring the perfection of the pot cover assembly, thereby realizing the unification of the air outlet of the pot cover assembly. Preferably, the pressure relief assembly in this embodiment is a pressure relief valve.

[0058] The pot cover assembly in this embodiment also includes a cover plate 14 and a third sealing ring 15. During actual installation, the cover plate 14 is placed on the guide groove 133. The gap between the cover plate 14 and the guide groove 133 is sealed by the third sealing ring 15, so that the airflow discharged from the exhaust hole 111 can be reliably transported to the pressure relief exhaust bin 134.

[0059] Preferably, the first sealing ring 31 , the second sealing ring 36 , the sealing pad 34 , and the third sealing ring 15 in this embodiment are all silicone structural parts.

[0060] In this embodiment, a limiting guide mechanism is provided between the movable shaft 32 and the inner wall of the limiting hole 132 along the length direction of the movable shaft 32. In the process of the movable shaft 32 moving up and down, the limiting guide mechanism can be used to limit and guide the movable shaft 32, thereby preventing the movable shaft 32 from being subjected to eccentric force, and improving the service life of the switching assembly 30 and the pot cover assembly in this embodiment. In actual setting, the structure for driving the movable shaft 32 to move up and down does not need to be set as a circular structure, and the shape can be varied to facilitate adapting to different design requirements of the product.

[0061] Specifically, the limiting guide mechanism in this embodiment includes a limiting guide groove and a limiting guide rib with clearance fit, one of which is arranged on the inner wall surface of the limiting hole 132, and the other is arranged on the outer wall surface of the movable shaft 32. In this embodiment, the limiting guide rib is arranged on the movable shaft 32, and the limiting guide groove is arranged on the inner wall surface of the limiting hole 132. When the movable shaft 32 moves up and down, the limiting guide rib on the movable shaft 32 slides along the limiting guide groove, so as to prevent the movable shaft 32 from being subjected to eccentric force.

[0062] According to the above-mentioned embodiments, the present invention directly connects the handle assembly 20 with the operating link 40 by rigidity. The operating link 40 and the buckle cover 12 are connected by the positioning pin 121 and the positioning hole 41. The movement of the operating link 40 will drive the movement of the buckle cover 12. At the same time, a wedge-shaped surface 43 with a slot 44 that can move in a circular motion is directly provided on the operating link 40. A switch assembly 30 that can be lifted and lowered and can be self-sealed up and down is provided on the concentric circle trajectory of the wedge-shaped surface 43. The switch assembly 30 is composed of a first sealing ring 31, a movable shaft 32, an elastic element 33, a sealing pad 34, a lifting and lifting plate 35 and a second sealing ring 36. The elastic element 33 controls the up and down movement of the switch assembly 30 and the size of the force required for sealing. The lifting and lifting plate 35 is to cooperate with the operating link 40 to realize the linkage with the handle assembly 20. The first sealing ring 31 ensures that the steam discharged from the exhaust hole 111 can be concentrated through the guide groove 133 and connected to the pressure relief exhaust bin 134, thereby realizing the unification of the air outlet.

[0063] The present invention, through the combined connection of the above-mentioned related bodies, finally realizes that when the pot cover assembly is directly covered, the wedge-shaped surface 43 will lift the switching assembly 30 under the action of the operating connecting rod 40, so as to realize the opening of the exhaust hole 111. In actual design, the cooking utensil of this embodiment is provided with an opening and closing lid detection program, so the program will display that the lid can be opened without pressure, and will automatically start the cooking-related program in the non-pressure working state. If the handle assembly 20 is turned, the exhaust hole 111 will be sealed under the joint action of the wedge-shaped surface 43 of the operating connecting rod 40 and the elastic element 33, and the buckle cover 12 will buckle with the inner pot 60, so that the lid cannot be opened directly. At the same time, due to the detection of the program, it will be displayed that there is pressure and the related programs will be carried out according to the standard of pressure.

[0064] It can be seen that the present invention integrates the handle assembly 20 and the operating link 40 into one by fixing the two with a direct rigid connection, and the handle assembly 20 is rotated to drive the operating link 40 to rotate. The operating link 40 is connected to the snap-fit ​​cover 12 through a pin hole, which also drives the rotation of the snap-fit ​​cover, and then the wedge surface 43 on the operating link 40 drives the switching assembly 30 to be raised and lowered, thereby realizing the opening and closing of the exhaust hole 111 on the inner cover assembly 11.

[0065] From the above description, it can be seen that the above-mentioned embodiments of the present invention achieve the following technical effects: the present invention effectively reduces the user operation steps, while maximizing the integration of related movable operating components, optimizing the product structure, and having only 3 sealing structures in total, with high quality stability.

[0066] For ease of description, spatially relative terms such as "above", "above", "on the upper surface of", "above", etc. may be used here to describe the spatial positional relationship between a device or feature and other devices or features as shown in the figure. It should be understood that spatially relative terms are intended to include different orientations of the device in use or operation in addition to the orientation described in the figure. For example, if the device in the accompanying drawings is inverted, the device described as "above other devices or structures" or "above other devices or structures" will be positioned as "below other devices or structures" or "below other devices or structures". Thus, the exemplary term "above" can include both "above" and "below". The device can also be positioned in other different ways (rotated 90 degrees or in other orientations), and the spatially relative descriptions used here are interpreted accordingly.

[0067] In addition, it should be noted that the use of terms such as "first" and "second" to limit components is only for the convenience of distinguishing the corresponding components. If not otherwise stated, the above terms have no special meaning and therefore cannot be understood as limiting the scope of protection of the present invention.

[0068] The above description is only a preferred 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 replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
