The embodiment provides a pressure cooker, as shown in fig. 1 to 14, which includes a cooker lid 100 and a cooker body 200, the cooker lid 100 is provided with a first handle 300, the cooker body 200 is provided with a second handle 400, the first handle 300 is provided with a sliding block 310, the sliding block 310 is provided with a stop pin 320, a first elastic member 330 is arranged between the sliding block 310 and the first handle 300, a second elastic member 340 is arranged between the sliding block 310 and the stop pin 320, the first handle 300 is provided with a limiting portion 350, and the second handle 400 is provided with a convex rib 410 and a reset portion 420.

As shown in fig. 7, 8 and 14, when the lid is closed, taking the pressure plan view angle of the present embodiment as an example, the pot lid 100 rotates clockwise relative to the pot body 200, when the protruding rib 410 rotates to touch the stop pin 320, the protruding rib 410 can push the stop pin 320 to move against the second elastic member 340, when the stop pin 320 is separated from the limiting part 350, the first elastic member 330 pushes the slider 310 to move, when the slider 310 moves to a specific position on the pressure cooker, an impact sound can be generated, and at this time, the slider 310 moves to a limit position.

As shown in fig. 2, 5 and 6, when the cover is opened, the pot cover 100 moves counterclockwise relative to the pot body 200, the reset part 420 pushes the sliding block 310 to move against the elastic force of the first elastic member 330, when the sliding block 310 slides to the vertex position of the reset part 420, the stop pin 320 is reset under the action of the second elastic member 340, and the limiting part 350 limits the stop pin 320 so that the sliding block 310 can be ejected again when the cover is closed next time.

When the cover is closed, the first elastic piece 330 pushes the sliding block 310 to move to generate impact sound, so that a user can be reminded of the cover closing in place, the blindness of judging whether the cover is closed in place or not is avoided, the risk that the cover cannot be closed in place is reduced, and the use safety of the pressure cooker is improved.

As shown in fig. 2, 5, 6 and 14, the rib 410 is L-shaped, the rib 410 includes a pushing portion 411 and a stopping portion 412, the first handle 300 is provided with a blocking rib 380 corresponding to the stopping portion 412, and when the lid is closed, the blocking rib 380 blocks the stopping portion 412 to prevent the lid 100 and the pot body 200 from further rotating relatively. Therefore, the pot cover 100 can be prevented from rotating excessively, the accuracy of cover closing is improved, the risk of extrusion of the sliding block 310 and the second handle 400 is reduced, and the sliding smoothness of the sliding block 310 is improved.

As shown in fig. 3, 4, 11, and 13, the slider 310 has an extension 311 extending to the lid 100, the extension 311 has a reducing hole 312, the lid 100 is provided with a float 110 penetrating the reducing hole 312, the float 110 has a reducing section corresponding to the reducing hole 312, when the float 110 floats upwards, a large diameter portion of the reducing section penetrates the large diameter hole of the reducing hole 312, when the float 110 falls, a small diameter portion of the reducing section penetrates the reducing hole 312 and can move the large diameter portion in the reducing hole 312, the outer diameter of the large diameter portion is larger than that of the small diameter hole, when the pressure cooker cooks, the float 110 floats upwards, the large diameter portion penetrates the large diameter hole but cannot slide into the small diameter hole, so as to avoid the slider 310 from resetting, because the slider 310 cannot move, the resetting portion 420 cannot push the slider 310, the lid 100 cannot relatively rotate with respect to the body 200, thereby avoiding the user's opening operation, and improving the safety of the pressure cooker.

As shown in fig. 4, the pot lid 100 is made of metal, and when the pot lid is closed, the sliding block 310 abuts against the pot lid 100. Therefore, the sliding block 310 can impact the metal pot cover 100, the impact sound is improved, and the prompt clarity is improved.

As shown in fig. 4 and 14, the second handle 400 has a reset groove 430, the reset portion 420 is located at the reset groove 430, and the slider 310 has a reset protrusion 313 protruding into the reset groove 430. In other alternative embodiments, the reset portion 420 may be embedded in the first handle 300.
