Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0030] In order to solve the problem in the prior art that when the lid of the electric pressure cooker is opened after cooking, the inner pot will be lifted up together, which will cause the food in the inner pot to splash out easily, thereby resulting in a poor user experience of the electric pressure cooker, the present invention provides a cooking utensil. It should be noted that the cooking utensil of the present application can be an electric pressure cooker or an electric rice cooker, but is not limited to the two. The illustrated embodiments of the present application take the electric pressure cooker as an example.

[0031] like Figures 1 to 10 As shown, the cooking utensil includes a pot cover 40, a pot body 10 and an inner pot 20. The pot cover 40 is openably and closably covered on the pot body 10. The inner pot 20 is arranged in the pot body 10. A locking structure 30 is arranged on the inner pot 20. The locking structure 30 is pivotally connected to the inner pot 20, and the locking structure 30 has a locking position in its rotation direction for engaging with the pot body 10 to position the inner pot 20, and an unlocking position for separating from the pot body 10 to allow the inner pot 20 to be freely taken and placed.

[0032] In the application, a locking structure 30 is provided on the inner pot 20, and the locking structure 30 is pivotally connected to the inner pot 20, wherein the locking structure 30 has a locking position in the rotation direction thereof, in which the locking structure 30 is engaged with the pot body 10 to position the inner pot 20, and an unlocking position in which the locking structure 30 is separated from the pot body 10 to allow the inner pot 20 to be in a free access state. Specifically, when the cooking utensil is in the cooking operation, the locking structure 30 is located in the locking position, thereby ensuring that the inner pot 20 cannot be taken out of the pot body 10, so that after the cooking is finished, when the user opens the pot cover, the inner pot 20 will not be lifted together due to the suction force of the sealing ring structure provided on the pot cover 40, effectively avoiding the food in the inner pot 20 from splashing out; after opening the pot cover 40, when the inner pot 20 needs to be taken out of the pot body 10, it is only necessary to rotate the locking structure 30 from the locking position to the unlocking position, so that the inner pot 20 can be smoothly taken out of the pot body 10, and the cooking utensil provided by the application has a good user experience.

[0033] like Figure 3 and Figure 4As shown, a lock hole 11 is provided on the pot body 10, and the lock structure 30 includes a rotating arm 31 and a positioning boss 32. The first end of the rotating arm 31 is pivotally connected to the inner pot 20, and the positioning boss 32 is arranged at the second end of the rotating arm 31. The positioning boss 32 extends into or exits the lock hole 11 with the rotation of the rotating arm 31, so that the lock structure 30 switches between the locked position and the unlocked position. In this way, by controlling the rotating arm 31 to rotate relative to the inner pot 20, the positioning boss 32 rotates with the rotating arm 31 and cooperates with the lock hole 11. When the positioning boss 32 extends into the lock hole 11, the lock structure 30 is in the locked position, and the inner pot 20 cannot move relative to the pot body 10; when the positioning boss 32 exits the lock hole 11, the lock structure 30 is in the unlocked position, and the inner pot 20 can move relative to the pot body 10.

[0034] Optionally, the positioning boss 32 extending into the lock hole 11 rotates a preset angle and then exits the lock hole 11, and the preset angle is greater than or equal to 10 degrees and less than or equal to 20 degrees. When the preset angle is too small, the lock buckle structure 30 is easy to move from the locked position to the unlocked position due to misoperation. When the preset angle is too large, the user needs to laboriously rotate the lock buckle structure 30 to move the lock buckle structure 30 from the locked position to the unlocked position. A large number of tests have shown that when the preset angle is greater than or equal to 10 degrees and less than or equal to 20 degrees, it can not only prevent the user from moving the lock buckle structure 30 from the locked position to the unlocked position due to misoperation, but also prevent the user from laboriously rotating the lock buckle structure 30 when it is necessary to move the lock buckle structure 30 from the locked position to the unlocked position.

[0035] In this application Figures 8 to 10 In the optional embodiment shown, the hole wall of the lock hole 11 at the hole opening on the side facing the lock structure 30 forms an annular guide slope 111.

[0036] like Figure 2 and Figure 3 As shown, the pot body 10 includes an outer shell 12 and a middle plate 13 disposed on the outer shell 12, and the lock hole 11 is opened on the middle plate 13. In this way, the pot body 10 is separated into the outer shell 12 and the middle plate 13 disposed on the outer shell 12, which can facilitate the processing of the pot body 10.

[0037] like Figure 8 As shown, the middle plate 13 includes a middle plate body 131 and a convex rib structure 132 , wherein the convex rib structure 132 is disposed on the middle plate body 131 , the locking hole 11 is opened on the convex rib structure 132 , and the locking hole 11 extends in the transverse direction.

[0038] like Figure 8As shown, a portion of the middle plate 13 is recessed to form an avoidance groove 133, and the rib structure 132 is disposed in the avoidance groove 133. The inner pot 20 includes an inner pot body 21 and a handle assembly 22 disposed on the inner pot body 21. The inner pot 20 is overlapped on the middle plate 13 through the handle assembly 22, and the handle assembly 22 is located at the position of the avoidance groove 133. In this way, the avoidance groove 133 can position the handle assembly 22, avoid relative rotation between the inner pot 20 and the pot body 10, and avoid misalignment between the lock hole 11 and the lock buckle structure 30.

[0039] like Figure 7 As shown, in order to facilitate the user to rotate the lock structure 30, the lock structure 30 also includes an operating handle 33, which is arranged on the surface of the rotating arm 31 on the side away from the positioning boss 32. In this way, when the lock structure 30 is in the locked position, the user can rotate the lock structure 30 by operating the handle 33 to switch the lock structure 30 from the locked position to the unlocked position.

[0040] like Figure 5 As shown, the inner pot 20 includes an inner pot body 21 and a handle assembly 22 disposed on the inner pot body 21, and the locking structure 30 is connected to an end of the handle assembly 22 away from the inner pot body 21. In this way, the locking structure 30 is pivotally connected to the inner pot body 21 through the handle assembly 22, and the inner pot 20 is split into the inner pot body 21 and the handle assembly 22 disposed on the inner pot body 21, which can facilitate the processing of the inner pot 20.
