[0023] 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.

[0024] As described in the background technology, the electric pressure cooker in the related art usually adopts a cold air rod to achieve the stop-opening function. Since the cold air rod needs to exhaust cold air, it will often move up and down, causing the food cooked in the pot to easily block the cold air rod, preventing it from sliding up and down smoothly, causing the stop-opening function to fail. When the consumer forcibly opens the lid, the cold air rod cannot stop opening, causing the steam in the pot to scald the consumer.

[0025] To solve the above problems, see Figures 1 to 4 As shown, an embodiment of the present invention provides a cooking utensil. The cooking utensil of this embodiment includes a pot body and a pot cover with a cover arranged on the pot body. A heating device is arranged inside the pot body. The pot cover includes a pot cover body and a lock cover 12 rotatably arranged in the pot cover body. The lock cover 12 has a locking position for locking relative to the pot body and an unlocking position for unlocking relative to the pot body. The pot cover also includes a handle assembly, and the handle assembly includes a handle 20, a rotating structure 21 and a transmission structure 22, wherein the handle 20 is rotatably mounted on the pot cover body; a first end of the rotating structure 21 is connected to the handle 20; the transmission structure 22 is arranged between the second end of the rotating structure 21 and the lock cover 12 to transmit the rotational force of the rotating structure 21 to the lock cover 12, so that the lock cover 12 can rotate between the locking position and the unlocking position, and the pressure in the pot body can act on the matching position between the lock cover 12 and the pot body to stop the lock cover 12 from rotating; a breaking portion 221 is arranged on the transmission structure 22, and when the rotational force is greater than a predetermined value, the breaking portion 221 is disconnected so that the rotational force of the rotating structure 21 cannot be transmitted to the lock cover 12.

[0026] The cooking utensil of the present invention comprises a handle assembly, which comprises a handle 20 rotatably mounted on a pot cover body, a rotating structure 21 connected to the handle 20, and a transmission structure 22 arranged between the rotating structure 21 and the locking cover 12, wherein the rotating force of the rotating structure 21 can be transmitted to the locking cover 12 through the transmission structure 22, thereby realizing the rotation of the locking cover 12 between a locked position and an unlocked position, and the pressure in the pot body can act on the matching position between the locking cover 12 and the pot body to stop the locking cover 12 from rotating, wherein a breaking portion 221 is arranged on the transmission structure 22, and when the rotating force is greater than a predetermined value, the breaking portion 221 is disconnected to make the rotation of the rotating structure 21 The force cannot be transmitted to the lock cover 12. When there is pressure inside the pot body, the pressure between the lock cover 12 and the pot body is relatively large. If the user forcibly rotates to open the cover, the rotational force will be greater than the predetermined value, so that before the lock cover 12 rotates, the transmission structure 22 breaks, and the rotation structure 21 cannot continue to drive the lock cover 12, preventing the user from continuing to open the cover. Especially when other anti-opening devices of the pot cover of the cooking utensil fail, the broken transmission structure 22 can effectively protect the user and prevent the user from being harmed by the pressure and water vapor inside the pot body, wherein the above-mentioned predetermined value is less than the friction between the lock cover 12 and the pot body, that is, before the relative movement between the lock cover 12 and the pot body occurs, the breaking portion 221 breaks.

[0027] See also Figure 4 As shown, the transmission structure 22 in this embodiment includes a transmission rod, and the breaking portion 221 includes a groove, which is arranged on the side wall of the transmission rod.

[0031] The pot body in this embodiment is provided with pot teeth, and the locking cover 12 is provided with cover teeth that match the pot teeth. When the pot teeth and the cover teeth match, the locking cover 12 is in a locked position, and when the pot teeth and the cover teeth are staggered, the locking cover 12 is in an unlocked position.

[0032] In order to prevent the transmission rod from slipping off the lock cover 12, causing the breaking portion 221 to fail to work normally, the bottom of the transmission rod in this embodiment is riveted to the lock cover 12, so that the bottom of the transmission rod is fixed more firmly. Of course, the connection method between the transmission rod and the lock cover 12 can also be other methods, such as threaded fastener connection, pin connection, etc.

[0033] In order to provide space for the movement of the transmission rod, the rotating structure 21 in this embodiment includes a pivot seat and a rotating rod. The pivot seat is connected to the handle 20, the first end of the rotating rod is connected to the pivot seat, the second end of the rotating rod is provided with a mounting notch, and a limiting flange 222 is provided on the top of the transmission rod. The transmission rod passes through the arc-shaped through hole and the mounting notch from bottom to top in sequence, and the limiting flange 222 overlaps the upper end of the mounting notch.
