DETAILED DESCRIPTION
[0025] The following will further describe the specific implementation of the utility model in combination with the accompanying drawings of the embodiments, so that the technical solution of the utility model is easier to understand and grasp. It should be understood that the specific embodiments described here are only used to explain the utility model, and are not used to limit the utility model.
[0026] This embodiment provides a pressure cooker, such as Figure 1-8 As shown, it includes a pot body 100 and a pot cover 200, the pot body 100 is provided with a lower handle 110, the pot cover 200 is provided with a self-locking safety valve 210, the lower handle 110 is provided with a boss 111, the pot cover 200 is provided with a rotatable blocking member 230 and a torsion spring 220 driving the blocking member 230 to rotate; when the pot cover 200 is correctly covered on the pot body 100, the boss 111 abuts against the blocking member 230 and drives the blocking member 230 to rotate, so that the blocking member 230 deviates from the self-locking safety valve 210; when the blocking member 230 is separated from the boss 111, the torsion spring 220 drives the blocking member 230 to rotate, so that the blocking member 230 blocks above the self-locking safety valve 210.
[0027] When the pot cover 200 is not covered on the pot body 100, the blocking member 230 is in the initial state, blocking the self-locking safety valve 210. When the pot cover 200 is not correctly covered on the pot body 100, the boss 111 will not drive the blocking member 230 to rotate, and the blocking member 230 will remain in the initial state, blocking the self-locking safety valve 210. The self-locking safety valve 210 will not rise, and the cooking space in the pot body 100 will not be in a sealed state, and the pot body 100 will not be pressed upward, reducing safety hazards. When the pot cover 200 is correctly covered on the pot body 100, the boss 111 will push the blocking member 230 to rotate, so that the blocking member 230 deviates from the top of the self-locking safety valve 210. At this time, the self-locking safety valve 210 can rise, achieving the purpose of high-pressure cooking of the pressure cooker. The pot cover 200 must be placed correctly to cook normally, preventing the pot cover 200 from being placed incorrectly.
[0028] like Figure 3-6As shown, the blocking member 230 is L-shaped. This facilitates flexible arrangement of the blocking member 230, the self-locking safety valve 210, and the boss 111. In other optional embodiments, the blocking member 230 may also be a straight rod.
[0029] like Figure 3 As shown, the blocking member 230 includes a baffle foot 231 and a baffle head 232. The blocking member 230 abuts against the boss 111 through the baffle foot 231. The blocking member 230 blocks the self-locking safety valve 210 through the baffle head 232. The blocking member 230 is provided with an axial hole 233. The pot cover 200 includes a cover 240. The cover 240 of the pot cover 200 is provided with a rotating shaft 241 that cooperates with the axial hole 233. The distance from the position where the blocking member 230 contacts the boss 111 to the rotation center of the blocking member 230 is less than the distance from the position where the blocking member 230 is located directly above the self-locking safety valve 210 to the rotation center of the blocking member 230. In this way, the small range movement of the position where the blocking member 230 contacts the boss 111 can realize the large range movement of the blocking member 230 located directly above the self-locking safety valve 210, ensuring that the blocking member 230 can stagger directly above the self-locking safety valve 210.
[0030] like Figure 6 As shown, the blocking member 230 is provided with a torsion spring hole 234 which is concentric with the shaft hole 233, the aperture of the torsion spring hole 234 is larger than the shaft hole 233, the side wall of the torsion spring hole 234 is provided with a first torsion spring foot slot 235, the cover 240 of the pot cover 200 is provided with an annular rib 242, the annular rib 242 surrounds the outer side of the rotating shaft 241, the annular rib 242 and the rotating shaft 241 are spaced to form a torsion spring slot 245, and the annular rib 242 is provided with a second torsion spring foot slot 243. The two ends of the torsion spring are respectively inserted into the first torsion spring foot slot 235 and the second torsion spring foot slot 243, the torsion spring is sleeved on the rotating shaft 241 and embedded in the torsion spring hole 234 and the torsion spring slot 245, so that the connection of the torsion spring is more stable. In other optional embodiments, two protrusions can also be provided on the cover 240 to form the second torsion spring foot slot 243.
[0031] like Figure 2 , 3 As shown, the upper surface of the boss 111 has an arc-shaped guide surface 112. When the pot cover 200 is placed on the pot body 100, the baffle foot 231 moves along the guide surface 112 to rotate the blocking member 230. In other optional embodiments, an arc surface can also be provided on the blocking member 230 simultaneously or separately.
[0032] like Figure 1 , 5As shown in FIGS. 7 and 8, upper handles 244 are provided at both ends of the surface cover 240, the rotating shaft 241 is located on the upper handle 244, a bottom cover 250 is provided at the lower end of the upper handle 244, the bottom cover 250 is fixed to the upper handle 244 by screws, the blocking member 230 is located above the bottom cover 250, a positioning hole 251 is provided on the bottom cover 250, and the boss 111 passes through the positioning hole 251. The pot cover 200 also includes a locking cover 260 that can rotate relative to the surface cover 240, and the surface cover 240 is positioned on the pot body 100 through the cooperation of the bottom cover 250 and the boss 111, so as to ensure that the surface cover 240 will not rotate relative to the pot body 100, and facilitate the control of the locking cover 260 to rotate and lock or unlock with the pot body 100. The surface cover 240 can block the positioning hole 251 on the bottom cover 250 to prevent the boss 111 from being exposed.
[0033] like Figure 8 As shown, the bottom cover 250 is provided with a circular hole 252, the circular hole 252 deviates from the center of the bottom cover 250, and the rotating shaft 241 penetrates the circular hole 252. This is conducive to the positioning of the bottom cover 250 during the assembly process and improves the assembly efficiency.
