[0002] A pressure cooker is a commonly used cooking appliance. When the pressure cooker stops heating after cooking is completed, the temperature inside the pressure cooker is very high, and the parts attached to the lid are relatively hot and inconvenient to touch directly. In order to save space, existing pressure cookers usually design a handle on the lid. After the pressure cooker is heated for a period of time, the heat inside the pressure cooker will be transferred to the handle. If the user mistakenly grasps the handle directly, it is easy to get burned. Summary of the invention

[0039] Locking blocks are symmetrically arranged at the bottom of the side arms 5 on the left and right sides of the handle 22, and locking holes 211 are arranged on the inner side of the pot cover clamp 21 at positions corresponding to the locking blocks.

[0040] The pot cover clamp 21 includes a clamp 212 and a connecting plate 213. The clamp 212 is fixedly connected to the outer bottom of the connecting plate 213. The locking hole 211 is arranged in the middle of the connecting plate 213. The driving slide column 331 is vertically arranged on the inner side of the connecting plate 213.

The inner sides of the two connecting plates extend into the connecting slide groove and can slide along the connecting slide groove.

[0041] In this solution, the pot cover is placed on the opening of the pot body, and the handle is pressed down. The handle moves downward and drives the first drive shaft to move downward. When the first drive shaft moves, the left and right ends of the first drive shaft move from the front side of the connecting hole on the corresponding side to the rear side. The movement of the first drive shaft drives the rotating shaft to rotate backward to the second position. When the rotating shaft moves to the second position, the lower part of the second spring top bead extends into the second top bead groove at the right end of the rotating shaft to lock the rotating shaft. During the backward rotation of the rotating shaft, the rotating shaft drives the second drive shaft to move upward through the second connecting member. During the movement of the second drive shaft, the spring enters a compressed state, and the rotating shaft drives the push rod to slide backward through the third connecting member. The push rod drives the push rod to slide backward through the push groove. The sliding plate slides backward along the slide seat, and the upper limit block limits the pushing plate when the push plate slides to prevent the pushing plate from tilting upward when sliding. During the backward movement of the pushing plate, the pushing plate squeezes the two driving slide posts to slide from the corresponding second positioning hole through the corresponding driving slide hole to the corresponding first positioning hole. During the sliding of the driving slide post, the lower part of the driving slide post slides inward along the corresponding guide hole, driving the connecting plate to slide inward along the connecting slide groove. The connecting plate drives the clamp on the corresponding side to clamp the corresponding side of the pot body and the lid body, so that the pot body and the pot lid are locked. At the same time, the locking hole on the connecting plate moves to the right below the locking block on the corresponding side, so that the locking block extends into the corresponding locking hole. At this time, the upper surface of the handle is flush with the upper surface of the mounting shell.

[0042] When the pot body and the pot cover need to be unlocked, the button is pressed, and the connecting column in the button drives the second driving shaft to move downward. During the movement of the second driving shaft, the top of the second driving shaft moves from the rear side of the accommodating groove to the front side of the accommodating groove during the process of pressing the button. During the movement of the second driving shaft, the second connecting member drives the rotating shaft to rotate forward from the second position to the first position. When the rotating shaft rotates forward, the rotating shaft pushes the second spring top bead out of the second top bead groove, and the rotating shaft is unlocked. When the rotating shaft rotates to the first position, the lower part of the first spring top bead extends into the first top bead groove on the left side of the rotating shaft to lock the rotating shaft. When the rotating shaft rotates forward, the first driving shaft is driven to move upward through the first connecting member. The first driving shaft is symmetrically provided at the left and right ends of the handle. The connecting hole drives the handle to extend upward to the installation shell, and the user can hold the extended handle, and the rotating shaft drives the pushing rod to move forward through the third connecting piece, and the pushing rod drives the sliding plate to slide forward along the sliding seat through the pushing groove. In the process of the pushing groove driving the pushing plate to move forward, the pushing plate squeezes the two driving slide posts to slide from the corresponding first positioning holes through the corresponding driving slide holes to the corresponding second positioning holes. In the process of the driving slide post sliding, the lower part of the driving slide post slides outward along the corresponding guide hole, driving the connecting plate to slide outward along the connecting slide groove, and the connecting plate drives the clamp on the corresponding side to loosen the corresponding side of the pot body and the cover body, so that the pot body and the pot cover are unlocked. After the pot body and the pot cover are unlocked, the user can lift the pot cover by the handle.

[0043] When the button is released, the spring returns to normal from the compressed state, the top of the spring drives the pressing plate to slide upward along the button slide groove, and the pressing plate drives the connecting column to move upward so that the top of the second drive shaft is out of the receiving groove.

[0044] When installing the sliding plate, press the sliding plate down to the bottom of the guide slot. During the pressing process of the sliding plate, the left and right side walls of the sliding plate squeeze the installation arm into the installation opening through the upper limit block. When the sliding plate is installed, the installation arm drives the upper limit block on the corresponding side to rebound inward, so that the upper limit block moves to the top of the corresponding side of the sliding plate.
