[0047] It should be noted that, in the absence of conflict, the embodiments and features in the embodiments of the present application can be combined with each other. The present invention will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0048] like Figures 1 to 11As shown, the cooking utensil of this embodiment includes: a pot body and a pot cover 10. The pot body is used to hold food to be cooked. The pot cover 10 is covered on the pot body, and the pot cover 10 includes an upper cover component 20, an inner cover component 30 and a cover component 40 arranged in sequence from the outside to the inside. The cover component 40 includes a cover bracket 41 and a cover 42 covered on the bottom of the cover bracket 41. The cover component 40 is provided with a first connecting structure and a second connecting structure to install the cover component 40 on the inner cover component 30. When the cover component 40 is installed on the inner cover component 30, the cover 42 covers one of the first connecting structure and the second connecting structure.

[0049] By applying the technical solution of this embodiment, when the cover assembly 40 is installed on the inner cover assembly 30, the cover 42 covers one of the first connection structure and the second connection structure. The above structure can prevent one of the first connection structure and the second connection structure with complex structures from being exposed, thereby making the appearance of the exposed part of the pot cover more neat and beautiful, solving the problem of the unsightly appearance of the pot cover of the cooking utensil in the prior art. In addition, since the cover assembly 40 is blocked below the inner cover assembly 30, the food will adhere to the cover assembly 40 instead of the inner cover assembly 30 during cooking, thereby making cleaning simple and improving the user experience.

[0050] like Figure 1 and Figure 2 As shown, in this embodiment, the cover assembly 40 is snap-connected to the inner cover assembly 30. The above structure is simple and convenient for users to install and disassemble, thereby improving the user experience.

[0051] like Figures 1 to 4 , Figures 6 to 8 As shown, in this embodiment, the cover 42 covers the first connection structure, the first connection structure includes a first hook 411, and the second connection structure includes a sliding buckle 412. The first hook 411 and the sliding buckle 412 are arranged at opposite ends of the cover bracket 41. The inner cover assembly 30 is provided with a slot 323 that cooperates with the first hook 411 and a second hook 333 that cooperates with the sliding buckle 412. After the first hook 411 is inserted into the slot 323, the sliding buckle 412 cooperates with the second hook 333 to install the cover bracket 41 on the inner cover assembly 30. Specifically, when installing, firstly insert the first hook 411 into the slot 323 on the inner cover assembly 30, and then rotate the cover assembly 40 with the first hook 411 as the rotation center, so that the cover assembly 40 gradually rotates toward the inner cover assembly 30. When the cover assembly 40 rotates to a predetermined position, the sliding buckle 412 can be engaged with the second hook 333 so that the cover assembly 40 can be stably assembled on the inner cover assembly 30. The above structure is simple, which not only makes installation easier, but also enables the cover assembly 40 to be firmly assembled on the inner cover assembly 30.

[0052] like Figures 1 to 3 , Figures 6 to 9 As shown, in this embodiment, a slide groove 1 is provided on the cover bracket 41, at least part of the sliding buckle 412 is movably provided in the slide groove 1, and an elastic recovery member 60 is provided between the sliding buckle 412 and the inner side wall of the slide groove 1. When the sliding buckle 412 is subjected to a force in a direction away from the second hook 333, the sliding buckle 412 moves in a direction away from the second hook 333. When the sliding buckle 412 is not subjected to an external force, the sliding buckle 412 moves toward the second hook 333 under the elastic force of the elastic recovery member 60 and cooperates with the second hook 333. Specifically, when installing the cover assembly 40, the first hook 411 is first inserted into the slot 323 on the inner cover assembly 30, and then the cover assembly 40 is rotated with the first hook 411 as the rotation center, so that the cover assembly 40 gradually rotates toward the inner cover assembly 30. When the cover assembly 40 rotates until the sliding buckle 412 thereon contacts the second hook 333, as the cover assembly 40 rotates, the second hook 333 applies an external force to the cover assembly 40, so that the sliding buckle 412 moves away from the second hook 333. In the above process, the elastic potential energy of the elastic recovery member 60 gradually increases. When the cover assembly 40 rotates to a predetermined position, the second hook 333 separates from the sliding buckle 412. At this time, the second hook 333 no longer applies an external force to the cover assembly 40, and the elastic recovery member 60 releases its elastic potential energy, so that the sliding buckle 412 moves toward the direction of the second hook 333, so that the sliding buckle 412 and the second hook 333 are engaged. The above structure is simple, and the elastic return member 60 can apply external force to the sliding buckle 412, so that the sliding buckle 412 tends to move toward the second hook 333, ensuring that the sliding buckle 412 does not separate from the second hook 333 when the cooking appliance is working, so that the covering assembly 40 can be firmly assembled on the inner cover assembly 30.

[0053] like Figures 1 to 3 , Figure 6 , Figures 8 to 10As shown, in this embodiment, the sliding buckle 412 includes a sliding portion 4121, a hook portion 4122 disposed on the side of the sliding portion 4121 close to the second hook 333, and a toggle portion 4123 disposed at the lower part of the sliding portion 4121. The bottom of the slide groove 1 is provided with an escape groove 11 for escaping the toggle portion 4123, and the toggle portion 4123 can move in a predetermined direction in the escape groove 11. Specifically, when the cover assembly 40 is mounted on the inner cover assembly 30, the lower surface of the hook portion 4122 abuts against the upper surface of the hook portion of the second hook 333. The above structure enables the hook portion of the second hook 333 to hold the hook portion 4122 so that the cover assembly 40 can be assembled on the inner cover assembly 30. When removing the cover assembly 40, the user moves the toggle portion 4123 in a predetermined direction so that the sliding buckle 412 is away from the second hook 333. When the sliding buckle 412 moves to the point where the lower surface of the hook portion 4122 is disengaged from the upper surface of the hook portion of the second hook 333, the cover assembly 40 can be removed from the inner cover assembly 30. The above structure provides the user with a convenient and quick way to remove the toggle portion 4123 of the cover assembly 40, thereby greatly improving the user's experience. In addition, the groove walls on both sides of the avoidance groove 11 can limit the toggle portion 4123 so that the toggle portion 4123 can only be moved in a predetermined direction.

[0054] like Figure 1 , Figure 3 and Figure 8 As shown, in this embodiment, the cover bracket 41 is provided with a receiving recess 413, the top of the receiving recess 413 is provided with a cover plate 70, and the cover plate 70 and the inner wall of the receiving recess 413 together form a slide groove 1. The above structure can prevent the sliding buckle 412 from moving up and down, thereby ensuring that the sliding buckle 412 and the second hook 333 can be buckled.

[0055] like Figure 1 , Figure 3 and Figure 6 As shown, in this embodiment, the inner cover assembly 30 includes an inner cover 31 and a first limit seat 32 arranged on the inner cover 31, the first limit seat 32 includes a first mounting section 321 and a matching section 322 arranged on both sides of the first mounting section 321, the first limit seat 32 is installed on the inner cover 31 through the first mounting section 321, and the slot 323 is formed on the matching section 322. Specifically, a first limit seat mounting hole is provided on the first mounting section 321, and a first inner cover mounting hole matching the first limit seat mounting hole is provided on the inner cover 31, and a fastener passes through the first limit seat mounting hole and the first inner cover mounting hole to fix the first limit seat 32 on the inner cover 31. Preferably, in this embodiment, the matching section 322 is a matching block, and the matching block is provided with a slot 323. The above structure is simple and easy to process. The first hook 411 has two hooks, and the matching blocks are two corresponding to the first hook 411. The above structure enables the cover assembly 40 to be firmly assembled on the inner cover assembly 30.

[0056] like Figure 1 , Figure 3 and Figure 7 As shown, in this embodiment, the inner cover assembly 30 includes an inner cover 31 and a second limit seat 33 disposed on the inner cover 31, the second limit seat 33 includes a second mounting section 331 and a limit seat extension section 332 disposed below the second mounting section 331, and the second hook 333 is formed on a side of the limit seat extension section 332 close to the sliding buckle 412. Specifically, a second limit seat mounting hole is provided on the second mounting section 331. A second inner cover mounting hole matching the second limit seat mounting hole is provided on the inner cover 31, and a fastener passes through the second limit seat mounting hole and the second inner cover mounting hole to fix the second limit seat 33 on the inner cover 31. The above structure is simple and easy to process and assemble.

[0057] like Figure 1 and Figure 4 As shown, in this embodiment, a pressure limiting valve assembly 51 is provided on the inner cover assembly 30, and a flow passage 421 is provided on the cover 42, so that the gas in the pot can be discharged to the outside through the flow passage 421 and the pressure limiting valve assembly 51. Specifically, when the food in the pot is heated, the gas will be discharged from the flow passage 421 to between the cover 42 and the inner cover 31, and the pressure limiting valve assembly 51 is provided on the inner cover 31. When the gas pressure between the cover 42 and the inner cover 31 is greater than a predetermined value, the pressure limiting valve assembly 51 opens to reduce the pressure value, thereby ensuring the safety of the cooking utensil.

[0058] like Fig.11 , Fig.26 and Fig. 27 As shown, in this embodiment, the cover 42 is provided with a foot 422, and the cover 42 is clamped to the bottom of the cover bracket 41 through the foot 422. Specifically, the cover bracket 41 is provided with a mounting hole. When the cover 42 is installed, the foot 422 of the cover 42 is passed through the mounting hole, and the part extending out of the mounting hole is bent to form a bent section, and the lower surface of the bent section abuts against the upper surface of the cover bracket 41 so that the cover 42 can be hooked on the cover bracket 41. The above structure is simple and easy to assemble. Of course, those skilled in the art should know that the installation method of the above cover 42 is not limited to this, and it can also be installed by bonding, welding, screw connection, etc.

[0059] like Figure 1 and Figure 5As shown, in this embodiment, a float 52 is also provided on the inner cover 31, and the float 52 can be a stop float or a cooling rod, etc. The cover 42 can cover the float 52 to make the appearance of the pot cover more beautiful. It should be noted that the pressure limiting valve assembly 51 and the float 52 are both one of the components to be shielded 50. Those skilled in the art should know that the components to be shielded 50 can also include other components to be shielded, such as a pressure measuring device, which are not listed here one by one.

[0060] like Figure 12 to Figure 14 As shown, in the present embodiment, the upper cover assembly 20 and the inner cover assembly 30 form a cover body assembly 80, the second connecting structure is slidably arranged, and the second connecting structure has a locking position and an unlocking position. When the second connecting structure is in the locking position, the second connecting structure can lock the cover assembly 40 on the cover body assembly 80, and when the second connecting structure is in the unlocking position, the cover assembly 40 can be removed from the cover body assembly 80. A buckle structure 90 is also provided on the cover assembly 40. When disassembling the cover assembly 40, pinch the buckle structure 90 and the second connecting structure. When the second connecting structure slides toward the buckle structure 90 to the unlocking position, the cover assembly 40 can be removed.

[0061] By applying the technical solution of this embodiment, a convex buckle structure 90 is provided on the cover assembly 40. When removing the cover assembly 40, the user moves the second connection structure with one finger and abuts the convex buckle structure 90 with another finger. When the second connection structure is moved to the unlocked position, the user pinches the second connection structure and the convex buckle structure 90 and applies force in a direction away from the cover assembly 80, so that the cover assembly 40 can be easily removed. The above structure makes it easier for the user to apply force when removing the cover assembly 40, so that the second connection structure can slide to the unlocked position more easily, thereby greatly improving the user's experience. The problem of inconvenient removal of the cover assembly 40 in the prior art is solved.

[0062] It should be noted that, generally, the index finger can be used to press against the convex buckle structure 90, and then the thumb can be used to move the second connection structure so that the second connection structure slides toward the convex buckle structure 90. The above action forms a "pinching" action. The above structure prevents the index finger from slipping, so that the thumb can more easily apply force to the second connection structure, so that the cover assembly 40 can be "pinched" down more easily.

[0063] Preferably, in this embodiment, when removing the cover assembly 40 , first use the index finger to press against the convex buckle structure 90 , and then use the thumb to move the toggle portion 4123 . The thumb cooperates with the surface of the toggle portion 4123 away from the convex buckle structure 90 .

[0064] like Figure 12 to Figure 14As shown, in this embodiment, the convex buckle structure 90 extends to the middle of the cover assembly 40, and there is a predetermined distance between the surface of the convex buckle structure 90 close to the cover assembly 40 and the inner surface of the cover assembly 40. The above structure allows a space for accommodating fingers between the surface of the convex buckle structure 90 close to the cover assembly 40 and the inner surface of the cover assembly 40, so as to facilitate user operation. In addition, the surface of the convex buckle structure 90 close to the cover assembly 40 is a first curved surface 91. The cooperation between the user's fingers and the curved surface can improve the user's hand feel when using, thereby improving the user's experience.

[0065] like Figure 12 to Figure 14 As shown, in this embodiment, the surface of the convex buckle structure 90 away from the cover assembly 40 is a second curved surface 92, and the curvature of the first curved surface 91 is smaller than the curvature of the second curved surface 92. The radius of the first curved surface 91 is smaller than the radius of the second curved surface 92. The above structure makes the height of the convex buckle structure 90 lower in the vertical direction, thereby reducing the volume of the product.

[0066] In other embodiments (not shown in the figure), the convex buckle structure 90 is a ring buckle. Specifically, when removing the cover assembly 40, first use the index finger to pass through the ring buckle, and then use the thumb to move the toggle portion 4123. The thumb cooperates with the surface of the toggle portion 4123 away from the convex buckle structure 90. The above structure is simple and convenient for users to operate.

[0067] like Figure 12 to Figure 14 As shown, in this embodiment, the convex buckle structure 90 is arranged on the outer wall of the receiving recess 413. The above structure is simple and easy to process. Preferably, in this embodiment, the convex buckle structure 90 and the receiving recess 413 are an integrally formed structure. The above structure improves production efficiency and reduces production costs.

[0068] like Figure 12 to Figure 14 As shown, in this embodiment, the convex buckle structure 90 is arranged on the outer wall of the accommodating recess 413 close to the middle of the covering assembly 40. The above structure is simple and convenient for users to disassemble.

[0069] like Figures 15 to 17As shown, in this embodiment, the pot cover 10 includes an inner liner 21 and an inner cover 31 arranged below the inner liner 21, and the cooking utensil also includes a component 120, a first seal 150 and a second seal 140. The component 120 includes a measuring device 121 and a mounting seat 122 for mounting the measuring device 121, the mounting seat 122 is penetrated on the inner liner 21, and the measuring device 121 is penetrated on the mounting seat 122 and extends into the pot body for measurement. The first seal 150 is arranged on the inner cover 31 and is located between the measuring device 121 and the inner cover 31 to seal the gap between the measuring device 121 and the inner cover 31. The second seal 140 is arranged on the inner liner 21 or the component 120, and the second seal 140 is located between the inner cover 31 and the mounting seat 122 to seal the gap 2 between the inner cover 31 and the mounting seat 122.

[0070] By applying the technical solution of this embodiment, the cooking utensil includes a first seal 150 for sealing the gap between the measuring device 121 and the inner cover 31 and a second seal 140 for sealing the gap 2 between the inner cover 31 and the mounting seat 122. The above structure enables the cooking utensil to have double sealing and good sealing. When the first seal 150 fails, the second seal 140 can still play a sealing role, thereby greatly increasing the safety of the cooking utensil and solving the problem of low safety of the cooking utensil in the prior art. In addition, since the second seal 140 is arranged on the lining 21 or the component 120, when the user disassembles the inner cover 31 for cleaning, it is only necessary to clean the first seal 150 installed on the inner cover 31, which is convenient for the user to clean and improves the user's experience.

[0071] like Fig.17 As shown, in this embodiment, the second sealing member 140 is disposed on the component 120. The above structure is simple and easy to disassemble and assemble.

[0072] like Figures 15 to 19 , Fig.21 and Fig. 22 As shown, in this embodiment, the component 120 includes a measuring device 121 and a mounting seat 122 for mounting the measuring device 121, the mounting seat 122 can be floated on the lining 21, the measuring device 121 extends into the pot body, and a gap 2 is provided between the bottom of the side wall of the mounting seat 122 and the inner cover 31, the second sealing member 140 includes a first skirt 141 and a second skirt 142 arranged on the circumferential outer side of the first skirt 141, the first skirt 141 abuts against the inner cover 31, and the second skirt 142 extends laterally into the gap 2 to seal the gap 2.

[0073] By applying the technical solution of this embodiment, the second sealing member 140 of the cooking utensil includes a first skirt 141 and a second skirt 142 arranged on the circumferential outer side of the first skirt 141. The first skirt 141 abuts against the inner cover 31, and the second skirt 142 extends transversely into the gap 2 to seal the gap 2 between the bottom of the side wall of the mounting seat 122 and the inner cover 31. When the pressure in the pot body increases, the gas in the pot body will abut against the first skirt 141 to move the first skirt 141 toward the gap 2. Since the gap 2 is sealed by the second skirt 142, the first skirt 141 will not enter the gap 2, thereby preventing the second sealing member 140 from failing, ensuring the safety of the cooking utensil, and solving the problem of low safety of the cooking utensil in the prior art.

[0074] like Figures 15 to 19 , Fig.21 and Fig. 22 As shown, in this embodiment, the second sealing member 140 includes a barrel section 143 and a third skirt 144 arranged at the upper end of the barrel section 143, the first skirt 141 and the second skirt 142 are located at the bottom of the barrel section 143, and the third skirt 144 extends to the inside of the barrel section 143 and is sandwiched between the measuring device 121 and the mounting seat 122. Specifically, when assembling the component 120, the second sealing member 140 is first sleeved on the measuring device 121, and then the measuring device 121 with the second sealing member 140 is inserted into the mounting hole of the mounting seat 122. When the measuring device 121 is inserted to a predetermined position, the measuring device 121 is divided into an inserted section and a non-inserted section by the mounting seat 122, and the third skirt 144 is sandwiched between the bottom of the mounting seat 122 and the non-inserted section. Finally, a nut is screwed on the inserted section to fasten the measuring device 121 to the mounting seat 122. At the same time, tightening the nut reduces the gap between the bottom of the mounting seat 122 and the unextended section, so that the third skirt 144 extending into the gap is firmly fixed. Therefore, the above structure is simple, and the second sealing member 140 can be fastened while assembling the components 120, which reduces the assembly steps, improves the assembly efficiency, and reduces the production cost.

[0075] like Fig.17 and Fig.18 , Fig.21 and Fig. 22As shown, in this embodiment, the measuring device 121 includes a temperature measuring device body 1211 and a temperature measuring probe 1212 arranged at the bottom of the temperature measuring device body 1211, the temperature measuring probe 1212 extends into the pot body, the temperature measuring device body 1211 has an annular flange 1214, and the third skirt 144 is sandwiched between the annular flange 1214 and the mounting seat 122. Specifically, when assembling the component 120, the second sealing member 140 is first sleeved on the measuring device 121, and the lower surface of the third skirt 144 is fitted with the upper surface of the annular flange 1214. Then the measuring device 121 is extended from bottom to top into the mounting hole of the mounting seat 122. When the measuring device 121 is extended to the predetermined position, the third skirt 144 is sandwiched between the bottom surface of the mounting seat 122 and the upper surface of the annular flange 1214, and finally the nut is screwed on the extending section. The above structure is simple and easy to process and assemble.

[0076] like Fig.18 and Fig.19 As shown, in this embodiment, the mounting seat 122 includes a mounting seat body 1221 and an extension tube 1222 disposed below the mounting seat body 1221, and the gap between the bottom of the extension tube 1222 and the inner cover 31 forms a gap 2. The above structure makes it unnecessary for the thickness of the second skirt 142 to be too thick, thereby facilitating processing and production, while reducing production costs.

[0077] like Fig.17 and Fig.18 As shown, in this embodiment, the outer wall of the barrel section 143 fits with the inner wall of the extension barrel 1222, and the upper surface of the third skirt 144 fits with the lower surface of the mounting seat body 1221. The above structure greatly increases the fitting area between the second sealing member 140 and the mounting seat 122, thereby greatly improving the sealing performance.

[0078] like Fig.17 and Fig.18 As shown, the inner cover 31 includes an inner cover body 312 and a mounting recess 313, a relief hole 311 for avoiding the components 120 is provided on the bottom wall of the mounting recess 313, and the first skirt 141 is located in the mounting recess 313 and abuts against the side wall of the mounting recess 313. Specifically, when the pressure in the pot body increases, the gas in the pot body will abut against the first skirt 141 so that the first skirt 141 is further pressed against the side wall of the mounting recess 313, thereby further preventing the gas in the pot body from flowing out from the gap between the inner cover 31 and the first skirt 141, thereby greatly improving the sealing performance.

[0079] like Fig.17 , Fig.18 , Fig.23 and Fig.24As shown, in this embodiment, the first seal 150 includes a seal body 151 and a first lip 152 and a second lip 153 arranged on the circumferential outer side of the seal body 151. The seal body 151 has a bottom wall and a side wall. The side wall is clamped between the component 120 and the hole wall of the avoidance hole 311. The inner surface of the side wall is a guide surface 154. The bottom wall is provided with a mounting hole 155. When the inner cover 31 is assembled to the upper cover assembly 20, the component 120 extends into the mounting hole 155 under the guidance of the guide surface 154. The first lip 152 is clamped between the component 120 and the upper surface of the inner cover 31, and the second lip 153 is in contact with the lower surface of the inner cover 31.

[0080] By applying the technical solution of this embodiment, the sealing body 151 of the first sealing member 150 has a bottom wall and a side wall, the side wall is sandwiched between the component 120 and the hole wall of the avoidance hole 311, and the inner surface of the side wall is a guide surface 154. When the first sealing member 150 needs to be installed on the component 120, the component 120 is aligned with the mounting hole 155 and extended into the mounting hole 155. During the extension process, the component 120 will cooperate with the guide surface 154. Under the guidance of the guide surface 154, the component 120 can smoothly enter the mounting hole 155 to complete the installation. The above structure makes installation more convenient and solves the problem of inconvenient installation of cooking utensils in the prior art. In addition, since the first lip 152 is sandwiched between the component 120 and the upper surface of the inner cover 31, and the second lip 153 is in contact with the lower surface of the inner cover 31, the above structure makes the contact area between the first sealing member 150 and the component 120 larger, thereby making the sealing better.

[0081] like Fig.18 and Fig.24 As shown, in this embodiment, the guide surface 154 is a guide slope, and the guide slope gradually shrinks inward from top to bottom. The above structure is simple and easy to process. Of course, those skilled in the art should know that the slope of the longitudinal section of the guide slope can remain unchanged or can have a certain change.

[0082] like Fig.18 , Fig.23 and Fig.24 As shown, in this embodiment, the temperature measuring probe 1212 extends into the mounting hole 155, and the bottom surface of the temperature measuring device body 1211 is in contact with the upper surface of the first lip 152, the guide surface 154, and the upper surface of the bottom wall. The above structure makes the contact area between the temperature measuring device body 1211 and the first sealing member 150 larger, thereby improving the sealing performance of the first sealing member 150.

[0083] like Fig.18As shown, in this embodiment, the temperature measuring device body 1211 includes a column portion 1213 and an annular flange 1214 disposed on the side wall of the column portion 1213, and the first lip 152 is sandwiched between the lower surface of the annular flange 1214 and the upper surface of the inner cover 31. The above structure is simple and easy to process. In addition, the setting of the annular flange 1214 can not only increase the contact area between the temperature measuring device body 1211 and the first sealing member 150, but also realize the installation of the first sealing member 150.

[0084] like Figures 16 to 25 As shown, in this embodiment, the pot body includes an inner pot 100, and the inner pot 100 is used to hold food to be cooked, and the cooking utensil also includes a sealing member 200. The sealing member 200 is sandwiched between the component 120 and the inner cover 31 to seal the gap between the component 120 and the inner cover 31, wherein when the pressure in the inner pot 100 is greater than a predetermined pressure, the component 120 and the inner cover 31 float up, and when the component 120 reaches the maximum stroke, the inner cover 31 can continue to float up to put the sealing member 200 in a compressed state.

[0085] By applying the technical solution of this embodiment, the seal 200 is sandwiched between the component 120 and the inner cover 31 to seal the gap between the component 120 and the inner cover 31. When the pressure in the inner pot 100 is greater than the predetermined pressure, the gas in the inner pot 100 pushes against the inner cover 31 to move upward, and the inner cover 31 drives the component 120 to float. When the component 120 reaches the maximum stroke and can no longer float, the stroke of the inner cover 31 has not reached the maximum stroke, that is, the inner cover 31 can still float. As the inner cover 31 floats, the seal 200 sandwiched in the gap between the inner cover 31 and the component 120 will be compressed due to external force, so that the seal 200 and the inner cover 31 and the component 120 fit more closely, thereby greatly improving the sealing effect and solving the problem of poor sealing of cooking utensils in the prior art.

[0086] It should be noted that the sealing member 200 includes a first sealing member 150 and a second sealing member 140. In addition, the gap between the sealing component 120 and the inner cover 31 includes a gap between the mounting seat 122 and the inner cover 31 and a gap between the measuring device 121 and the inner cover 31. The first sealing member 150 is used to seal the gap between the measuring device 121 and the inner cover 31. The second sealing member 140 seals the gap between the mounting seat 122 and the inner cover 31.

[0087] like Figures 15 to 18 As shown, in this embodiment, the component 120 is a temperature measuring component to measure the temperature in the inner pot 100. By detecting the temperature of the gas in the inner pot 100, the heating strategy of the cooking appliance can be adjusted in real time. Of course, those skilled in the art should know that the above-mentioned component 120 is not limited to a temperature measuring component, and can also be a pressure measuring component.

[0088] like Fig.17 , Fig.18 and Fig. 20 As shown, in this embodiment, the liner 21 is provided with an assembly hole 211 for installing the mounting seat 122, and the mounting seat 122 is provided with a stop structure 1223. The mounting seat 122 is hung at the assembly hole 211 through the stop structure 1223 to prevent the mounting seat 122 from escaping from the assembly hole 211 under the action of gravity. Specifically, in the present application, a mounting cylinder is provided on the liner 21, and the inner surface of the mounting cylinder forms the assembly hole 211. When the gas pressure in the inner pot 100 reaches a predetermined value, the stop structure 1223 moves away from the mounting cylinder. When the gas pressure in the inner pot 100 is not enough to overcome the gravity of the inner cover 31 and the component 120, the mounting seat 122 begins to descend. The stop structure 1223 moves toward the direction of the mounting cylinder and is finally hung on the upper end of the mounting cylinder (that is, the lower surface of the stop structure 1223 abuts against the upper end of the mounting cylinder)

[0089] like Fig.16 , Fig.17 , Fig.19 and Fig. 20 As shown, in this embodiment, a pressure cap 210 is provided on the inner liner 21, and an elastic reset mechanism 220 is provided between the pressure cap 210 and the mounting seat 122. When the pressure in the inner pot 100 is greater than the predetermined pressure, the mounting seat 122 floats up, and the elastic reset mechanism 220 is compressed. When the component 120 reaches the maximum stroke, the stop structure 1223 of the mounting seat 122 abuts against the stop surface 230 of the pressure cap 210. When the pressure in the inner pot 100 decreases, the mounting seat 122 can move downward under the elastic restoring force of the elastic reset mechanism 220 and the action of gravity. The above structure is simple and easy to process.

[0090] like Fig.16 , Fig.17 and Fig.25As shown, in this embodiment, the pot cover 10 further includes a locking ring 22 rotatably arranged below the inner lining 21, a cover tooth is arranged on the locking ring 22, and a pot tooth is arranged on the pot body, and the cover tooth and the pot tooth cooperate to lock the pot cover 10 on the pot body, and in the vertical direction, the minimum distance H between the inner cover 31 and the locking ring 22 is greater than the distance D between the upper surface of the stop structure 1223 and the stop surface 230. Specifically, when the pressure in the inner pot 100 is greater than the predetermined pressure, the gas in the inner pot 100 pushes against the inner cover 31 to move upward, and the inner cover 31 drives the component 120 to float. When the upper surface of the stop structure 1223 of the component 120 contacts the stop surface 230, the component 120 reaches the maximum stroke and cannot continue to float. However, since the minimum distance H between the inner cover 31 and the locking ring 22 is greater than the distance D between the upper surface of the stop structure 1223 and the stop surface 230, the inner cover 31 can continue to rise, and the sealing member 200 can be squeezed, thereby achieving the purpose of improving the sealing performance of the cooking utensil. The above structure is simple and easy to implement.

[0091] Preferably, in this embodiment, HD is less than or equal to 5 mm. Further preferably, HD is between 0.5 mm and 2 mm. The above structure enables the sealing effect of the sealing member 200 to be optimal.

[0092] like Fig.16 , Fig.17 , Fig.19 and Fig. 20 As shown, in this embodiment, a lid opening handle 240 is provided on the inner liner 21, and the lid opening handle 240 is pivotally provided on the pressure cover 210, and the lid opening handle 240 has a first position and a second position. When the lid opening handle 240 is rotated to the first position, the pot teeth and the cover teeth are matched, and when the lid opening handle 240 is rotated to the second position, the pot teeth and the cover teeth are separated. The pressure cover 210 can serve as a pivot axis of the lid opening handle 240 and can also stop the mounting seat 122, so the above structure can realize two functions at the same time, and finally reduce the production cost.

[0093] like Fig.16 , Figure 25 to Figure 27 As shown, in this embodiment, the cooking utensil also includes: a sealing ring 110, which is arranged on the pot cover 10, and the sealing ring 110 includes a third lip 111 and a fourth lip 112. The third lip 111 seals the gap between the inner cover assembly 30 and the inner pot 100, and the fourth lip 112 seals the gap between the inner cover assembly 30 and the covering assembly 40.

[0094] By applying the technical solution of this embodiment, the cooking utensil further comprises a sealing ring 110, the sealing ring 110 comprises a third lip 111 and a fourth lip 112, the third lip 111 seals the gap between the inner cover assembly 30 and the inner pot 100, and the fourth lip 112 seals the gap between the inner cover assembly 30 and the cover assembly 40. The above structure can achieve the sealing of the inner cover assembly 30 and the inner pot 100 and the sealing of the inner cover assembly 30 and the cover assembly 40 through the same sealing ring 110, thereby greatly reducing the production cost and solving the problem of high production cost of the cooking utensil in the prior art. In addition, since only one sealing ring 110 needs to be installed during installation, the above structure can also greatly improve the installation efficiency.

[0095] like Fig.25 and Fig. 27 As shown, in this embodiment, the fourth lip 112 extends toward the middle of the inner cover assembly 30, and the fourth lip 112 bends toward the inner cover assembly 30. Specifically, when the fourth lip 112 is subjected to an upward extrusion force (the above extrusion force may be caused by the cover assembly 40 or the gas pressure in the pot body), the fourth lip 112 will be pressed toward the inner cover assembly 30, so that the contact area between the fourth lip 112 and the inner cover assembly 30 is larger, thereby improving the sealing performance.

[0096] like Fig. 27 As shown, in this embodiment, the cover assembly 40 is detachably arranged on the inner cover assembly 30, and the cover assembly 40 is installed after the sealing ring 110 is installed on the inner cover assembly 30 so that the fourth lip 112 is sandwiched between the inner cover assembly 30 and the cover assembly 40. Specifically, during installation, the sealing ring 110 is first installed on the inner cover assembly 30, at which time the fourth lip 112 is partially attached to the inner cover assembly 30. Then, the first hook 411 of the cover assembly 40 is inserted into the slot 323 on the inner cover assembly 30, and then the cover assembly 40 is rotated with the first hook 411 as the rotation center, so that the cover assembly 40 gradually rotates toward the inner cover assembly 30. When the sliding buckle 412 is buckled with the second hook 333, the fourth lip 112 is sandwiched between the inner cover assembly 30 and the cover assembly 40. The above structure is simple and easy to assemble.

[0097] like Fig.11 , Figure 25 to Figure 27 As shown, in this embodiment, the cover assembly 40 includes a cover 42 and a cover bracket 41, the cover 42 is fixed to the inner cover assembly 30 through the cover bracket 41, and the fourth lip 112 is sandwiched between the cover bracket 41 and the inner cover assembly 30. The above structure is simple and easy to install.

[0098] like Figure 25 to Figure 27As shown, in this embodiment, the sealing ring 110 further includes a fifth lip 113, and the sealing ring 110 is fixed to the inner cover assembly 30 via the fifth lip 113. The above structure is simple, easy to assemble and has good sealing performance.

[0099] like Fig.25 As shown, in this embodiment, the inner cover assembly 30 includes a sealing ring fixing frame 34 arranged at the edge of the inner cover 31, and the fifth lip 113 is sandwiched between the inner cover 31 and the sealing ring fixing frame 34. The above structure enables the sealing ring 110 to be firmly installed on the inner cover assembly 30, thereby ensuring the reliability of the sealing ring 110. However, those skilled in the art should know that the manner in which the sealing ring 110 is installed on the inner cover assembly 30 is not limited to this, and can also be bonded or connected by fasteners.

[0100] like Fig.25 As shown, in this embodiment, a receiving groove 341 is provided on the surface of the sealing ring fixing frame 34 facing the inner cover 31, and the end of the fifth lip edge 113 extends into the receiving groove 341. Specifically, during installation, the end of the fifth lip edge 113 is first extended into the receiving groove 341 to fix the position of the sealing ring 110, and then the sealing ring fixing frame 34 with the sealing ring 110 assembled is fixed on the inner cover 31 to complete the installation of the inner cover assembly 30. Therefore, the above structure prevents the sealing ring 110 from shifting when the inner cover 31 is installed, thereby making the installation of the sealing ring 110 more convenient.

[0101] like Fig.25 and Fig. 27 As shown, in this embodiment, the third lip 111 includes a first extension section 1111 extending transversely and a second extension section 1112 connected to the first extension section 1111 and extending vertically, the first extension section 1111 is connected to the fourth lip 112, the upper surface of the first extension section 1111 is in contact with the lower surface of the sealing ring fixing frame 34, and the outer surface of the second extension section 1112 is in contact with the inner surface of the inner pot 100. If the gas in the pot overflows from the gap between the fourth lip 112 and the inner cover 31, it will be secondary sealed by the first extension section 1111 to further improve the sealing performance of the sealing ring 110.

[0102] like Fig.25 and Fig. 27 As shown, in this embodiment, an annular groove 314 is provided at the edge of the bottom of the inner cover 31, and the sealing ring fixing frame 34 is an annular fixing frame provided in the annular groove 314. There is a gap between the groove wall of the annular groove 314 and the inner ring of the annular fixing frame, and the third lip edge 111 extends into the gap for sealing. The above structure increases the contact area between the third lip edge 111 and the groove wall of the annular groove 314 and the inner ring of the annular fixing frame, thereby further improving the sealing performance.

[0103] like Fig.16 , Fig.18 and Fig.19 As shown, in this embodiment, the cooking appliance includes a stopper and a buffer 170. When the pressure in the pot body is greater than a predetermined pressure, the component 120 floats up, and when the component 120 floats up to the maximum stroke, the component 120 is stopped by the stopper. The buffer 170 is arranged between the stopper and the component 120 to reduce the impact between the stopper and the component 120.

[0104] By applying the technical solution of this embodiment, the cooking utensil includes a buffer 170. When the pressure in the pot body is greater than a predetermined pressure, the component 120 floats up. Since the buffer 170 is arranged between the stopper and the component 120, when the component 120 contacts the stopper, the buffer 170 can absorb a part of the energy, so that the impact force of the component 120 on the stopper is reduced, thereby reducing the deformation of the stopper and extending the life of the cooking utensil. The problem of short life of the cooking utensil in the prior art is solved.

[0105] like Fig.16 , Fig.18 and Fig.19 As shown, in this embodiment, the buffer member 170 is disposed between the mounting seat 122 and the stopper. The above structure is simple and easy to implement.

[0106] like Fig.16 , Fig.18 and Fig.19 As shown, in this embodiment, the buffer member 170 is arranged on the mounting seat 122. The above structure is simple and easy to assemble. Of course, those skilled in the art should know that the buffer member 170 can also be arranged on the stopper.

[0107] like Fig.16 , Fig.18 and Fig.19 As shown, in this embodiment, the buffer 170 is disposed on the stop structure 1223. Since the distance between the stop structure 1223 and the stopper is small, arranging the buffer 170 on the stop structure 1223 can make the buffer 170 thinner, thereby facilitating processing and reducing production costs.

[0108] like Fig.16 , Fig.18 and Fig.19 As shown, in this embodiment, the buffer member 170 is a buffer washer, and the buffer washer is made of a soft material. It should be noted that the soft material refers to a material such as silica gel, rubber, sponge, etc. that can reduce the impact between two components.

[0109] It should be noted that, in this embodiment, the stopper is a pressure cover 210. The pressure cover 210 can serve as the pivot axis of the cover opening handle 240 and can also stop the mounting seat 122, so the above structure can achieve two functions at the same time, ultimately reducing the production cost.

[0110] In this embodiment, the cooking appliance is an electric pressure cooker.

[0111] In this embodiment, the cooking appliance further comprises a heating device arranged in the pot body, for heating the food in the pot body.

[0112] 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.
