[0044] like Figure 1As shown, the cooking utensil of this embodiment includes a pot body, a pot cover 10 and a positioning structure 20. The pot body is used to hold the food to be cooked, and the pot cover 10 is arranged on the pot body. The pot cover 10 includes a pot cover body 11 and an inner pot cover 12 detachably arranged on the pot cover body 11, and a mounting hole 121 is arranged on the inner pot cover 12. The positioning structure 20 is arranged on the pot cover body 11, and the positioning structure 20 includes a mounting seat 21, a stopper 22 movably arranged on the mounting seat 21, a first elastic structure 23 arranged in the mounting seat 21 and cooperating with the stopper 22, and an unlocking member 24 cooperating with the stopper 22. The stopper 22 has a stop position and an avoidance position. When the unlocking member 24 is not operated, the first elastic structure 23 makes the stopper 22 in the stop position. When the unlocking member 24 is operated, the stopper 22 moves from the stop position to the avoidance position. When installing the inner pot cover 12, the positioning structure 20 passes through the mounting hole 121, and the stop block 22 abuts against the lower surface of the inner pot cover 12 to position the inner pot cover 12 on the pot cover body 11. When removing the inner pot cover 12, the unlocking piece 24 is operated to disengage the positioning structure 20 from the mounting hole 121.

[0045] By applying the technical solution of this embodiment, when installing the inner pot cover 12, the positioning structure 20 is passed through the mounting hole 121, and the stopper 22 is retracted and then extended and limited on the lower surface of the inner pot cover 12. When removing the inner pot cover 12, the unlocking member 24 is operated and the stopper 22 is retracted, and the positioning structure 20 can be disengaged from the mounting hole 121. The above structure allows the entire operation of installing and removing the inner pot cover 12 without the need for a nut structure, and the steps are simple and convenient. Therefore, the technical solution of this embodiment solves the problems of inconvenient installation and removal of the inner pot cover of the electric pressure cooker in the prior art, and the nut is easily over-tightened and lost.

[0046] like Figure 2 , Figure 6 and Figure 7 as well as Figure 8 As shown, in the technical solution of this embodiment, the mounting seat 21 is provided with a first avoidance opening 212, and the stop block 22 is provided with a first anti-slip structure 30, and the first anti-slip structure 30 prevents the stop block 22 from slipping out of the first avoidance opening 212. Specifically, after the stop block 22 passes through the first avoidance opening 212, the portion of the stop block 22 located outside the mounting seat 21 forms a stop structure. When the unlocking member 24 is not operated, the first elastic structure 23 pushes the stop block 22 and places the stop block in the stop position.

[0047] When the inner pot cover 12 is installed, the inner pot cover 12 is installed from bottom to top, and the mounting hole 121 passes through the mounting seat 21. During the movement of the inner pot cover 12, the end surface of the mounting hole 121 pushes the stop block 22 and makes the stop block 22 move toward the inside of the mounting seat 21 and pass through the mounting hole 121. After the stop block 22 passes through the mounting hole 121, the stop block 22 is reset under the action of the first elastic structure 23 and stops at the lower surface of the inner pot cover 12.

[0048] When removing the inner pot cover, the unlocking member 24 is operated to move the stopper 22 toward the inside of the mounting seat 21, and the mounting seat 21 can be disengaged from the mounting hole 121, and the inner pot cover 12 can be removed. The unlocking member 24 is released, and the stopper 22 is reset under the action of the first elastic structure 23.

[0049] like Figure 6 , Figure 7 , Fig. 9 and Fig.10 As shown, in the technical solution of this embodiment, the mounting seat 21 includes an annular side wall 211, a first escape opening 212 is formed on the annular side wall 211, and a first anti-slip structure 30 includes an anti-slip convex rib arranged on the stop block 22, and the anti-slip convex rib cooperates with the inner surface of the annular side wall 211. Specifically, the annular side wall 211 forms a cylindrical structure, and the cross section of the annular side wall 211 is circular. The first escape opening 212 is formed on the annular side wall 211. The side of the stop block 22 is provided with an anti-slip convex rib, and preferably, the opposite sides of the stop block 22 are provided with anti-slip convex ribs. When the stop block 22 is installed, the stop block 22 is first placed inside the annular side wall 211, and then the stop block 22 passes through the first escape opening 212 from the inside to the outside. In the process of the stop block 22 passing out, the anti-slip convex rib abuts and cooperates with the inner side wall of the annular side wall 211, thereby preventing the stop block 22 from falling out of the first escape opening 212.

[0050] Of course, in addition to the above structure, the first anti-slip structure 30 can also be in other forms. For example, the stop block 22 can be a wedge-shaped structure, and the maximum cross-sectional area of ​​the stop block 22 is larger than the area of ​​the first avoidance opening 212, that is, a part of the stop block 22 can pass through the first avoidance opening 212. At this time, the wedge-shaped outer side of the stop block 22 forms the first anti-slip structure 30.

[0051] like Figure 2As shown, in the technical solution of this embodiment, there are two stop blocks 22, and the first elastic structure 23 is arranged between the two stop blocks 22. Correspondingly, there are also two first avoidance openings 212, and the two first avoidance openings 212 are arranged opposite to each other. The two stop blocks 22 are respectively inserted into the two first avoidance openings 212, and the first elastic structure 23 is a spring, and the two ends of the spring are respectively fixed on the stop blocks 22. The spring applies force to the two stop blocks 22 respectively and makes the two stop blocks 22 both in the stop position. Preferably, the center line of the two first avoidance openings 212 passes through the center line of the annular side wall 211, so that the force applied by the spring to the two stop blocks 22 is in the same straight line, thereby making the structure more stable. Further preferably, a positioning column is provided on the inner end face of the stop block 22, and the end of the spring is sleeved outside the positioning column, thereby facilitating the installation of the spring and preventing the spring from slipping off.

[0052] like Figures 5 to 7 ,as well as Fig. 9 As shown, in the technical solution of this embodiment, the unlocking member 24 is a sleeve structure with an upper end opening, and the unlocking member 24 is sleeved on the mounting seat 21 from bottom to top, and the unlocking member 24 can slide up and down relative to the mounting seat 21, and a guide surface 221 is provided on the surface of the stop block 22 facing the unlocking member 24, and when the unlocking member 24 slides upward, the unlocking member 24 presses the guide surface 221 to move the stop block 22 from the stop position to the avoidance position. Specifically, when the unlocking member 24 is not operated, the unlocking member 24 does not interfere with the stop block 22. When the unlocking member 24 is pressed upward, the unlocking member 24 contacts the guide surface and forces the stop block 22 to move toward the inside of the annular side wall 211. When the unlocking member 24 is released, the unlocking member 24 is separated from the stop block 22, and the stop block is reset and re-positioned to the stop position under the action of the first elastic structure 23.

[0053] like Figure 7 As shown, in the technical solution of this embodiment, a second anti-slip structure 40 is provided between the unlocking member 24 and the mounting seat 21, and the second anti-slip structure 40 prevents the unlocking member 24 from slipping off from the mounting seat 21 from top to bottom. Specifically, the unlocking member 24 can slide up and down on the mounting seat 21, and the second anti-slip structure 40 can prevent the unlocking member 24 from slipping off downward and limit the unlocking member 24 on the mounting seat 21.

[0054] like Figure 8 and Fig. 9As shown, in the technical solution of this embodiment, the second anti-slip structure 40 includes a positioning hook 41 and a card platform 42. The positioning hook 41 is arranged on the inner side wall of the unlocking member 24. The card platform 42 is arranged on the outer side wall of the annular side wall 211, and the positioning hook 41 is hooked on the card platform 42. When the unlocking member 24 is opened, the unlocking member 24 moves downward. After the unlocking member 24 moves downward a certain distance, the positioning hook 41 hooks the card platform 42 and prevents the unlocking member 24 from falling out downward. Of course, the second anti-slip structure 40 is not limited to the above-mentioned structure. For example, the second anti-slip structure 40 may include an annular convex edge arranged on the inner wall of the unlocking member 24 and an annular card platform arranged outside the annular side wall 211. The specific structure of the second anti-slip structure 40 can be designed by those skilled in the art according to actual working conditions.

[0055] like Figure 8 and Fig. 9 As shown, in the technical solution of this embodiment, the clamping platform 42 is formed by cutting the outer side wall of the annular side wall 211. Further preferably, the positioning hook 41 is formed by first processing two parallel slits at the end of the unlocking member 24, and then bending the portion between the slits inward to form the above-mentioned positioning hook 41. The above-mentioned structure is easy to process and has a reliable structure.

[0056] like Figure 8 and Fig. 9 As shown, in the technical solution of this embodiment, a second escape opening 241 is provided on the side wall of the unlocking member 24, and the second escape opening 241 and the first escape opening 212 are provided correspondingly, and the stop block 22 sequentially passes through the first escape opening 212 and the second escape opening 241 to remain in the stop position. Specifically, the first escape opening 212 and the second escape opening 241 have the same shape, and the stop block 22 extends out of the mounting seat 21 after passing through the first escape opening 212 and the second escape opening 241 respectively. Specifically, when the unlocking member 24 is pushed upward, the second escape opening 241 and the first escape opening 212 are misaligned, and the lower surface of the second escape opening 241 (at Fig. 9 The upper surface in the middle) pushes the guide surface 221. After the unlocking member 24 is released, the unlocking member 24 moves downward, the lower surface of the second avoidance opening 241 no longer presses the guide surface 221, and the stop block 22 is reset under the action of the spring.

[0057] like Figure 2 , Figure 6 and Figure 7 As shown, in the technical solution of this embodiment, a second elastic structure 50 is provided between the mounting seat 21 and the unlocking member 24, and the second elastic structure 50 applies an elastic force in a direction away from the mounting seat 21 to the unlocking member 24. Specifically, after the unlocking member 24 is pressed and then released, the second elastic structure 50 pushes the unlocking member 24 and resets the unlocking member 24. Preferably, the second elastic structure 50 is a spring structure.

[0058] like Figure 2 , Figure 6 and Figure 7 as well as Fig.13 As shown, in the technical solution of this embodiment, the mounting seat 21 further includes a baffle 25 disposed in the annular side wall 211, and the baffle 25 prevents the stop block 22 from slipping out from below the annular side wall 211. Specifically, the baffle 25 is installed upward from the lower end of the annular side wall 211. Preferably, the baffle 25 and the annular side wall 211 are detachably connected, thereby facilitating the assembly of the stop block 22 and the first elastic structure 23. There are various connection methods between the baffle 25 and the annular side wall 211, such as a snap connection, a screw connection, etc.

[0059] like Figure 2 , Figure 6 and Figure 7 as well as Figure 8 and Fig.11 As shown, in the technical solution of the present embodiment, the mounting seat 21 also includes a top wall 213 arranged above the annular side wall 211, and the positioning structure 20 also includes a fixing seat 26 fixedly arranged on the pot cover body 11, a threaded column 214 is arranged on the top wall 213, and a threaded hole 261 is arranged on the fixing seat 26, and the threaded column 214 is screwed into the threaded hole 261 to fix the mounting seat 21 on the pot cover body 11. Specifically, the fixing seat 26 is fixed below the lining 111, and when the mounting seat 21 is installed, the threaded column 214 is screwed into the threaded hole 261 to fix the mounting seat 21. The above structure is simple to install and is easy to disassemble and replace. Of course, the mounting seat 21 and the fixing seat 26 can be connected in other ways, such as screw connection.

[0060] like Figure 2 , Figure 6 and Figure 7 as well as Fig.12 As shown, in the technical solution of this embodiment, the positioning structure 20 also includes a sealing ring 27 sandwiched between the mounting seat 21 and the fixing seat 26. When the inner pot cover 12 is installed on the pot cover body 11, the sealing ring 27 abuts against the upper surface of the inner pot cover 12. Specifically, the sealing ring 27 is used to seal the mounting hole 121. After the inner pot cover 12 is installed, the lower end of the sealing ring 27 abuts against the upper surface of the inner pot cover 12, thereby preventing the steam in the pot body from flowing into the gap between the mounting hole 121 and the mounting seat 21 between the inner pot cover 12 and the pot cover body 11. Preferably, the sealing ring 27 is bowl-shaped, and a mounting through hole is provided on the sealing ring 27. The sealing ring 27 is sleeved on the outside of the threaded column 214 through the mounting through hole. In the process of rotating the mounting seat 21, the top wall 213 and the fixing seat 26 can clamp the sealing ring 27.

[0061] like Figures 3 to 7As shown, in the technical solution of this embodiment, the cooking utensil further includes an elastic push mechanism 60 disposed on the pot cover body 11. When the inner pot cover 12 is installed on the pot cover body 11, the elastic push mechanism 60 applies an elastic force in a direction away from the pot cover body 11 toward the inner pot cover 12. Specifically, after the inner pot cover 12 is installed, the elastic push mechanism 60 is compressed. When the unlocking member 24 is pressed and the stopper 22 is placed in the unlocking position, the elastic push mechanism 60 applies an elastic force toward the inner pot cover 12 and the inner pot cover 12 automatically comes out, thereby preventing the inner pot cover 12 and the pot cover body 11 from being stuck together due to steam or sticky food, which makes it difficult for the user to remove the inner pot cover 12.

[0062] like Figure 3 and Figure 6 As shown, in the technical solution of this embodiment, the pot cover body 11 includes an inner lining 111 and a surface cover 112 arranged on the inner lining 111, and the elastic pushing mechanism 60 includes a pushing column 61 arranged on the inner lining 111 and a third elastic structure 62 arranged between the pushing column 61 and the inner lining 111. Specifically, the pushing column 61 is in a cap shape, and a positioning convex edge is provided at the end of the pushing column 61. The positioning convex edge hook is arranged on the installation position in the inner lining 111 and prevents the pushing column 61 from falling out downward. The third elastic structure 62 is a spring, and the two ends of the spring are respectively in contact with the inner lining 111 and the pushing column 61 and apply elastic force toward the pushing column 61.
