[0032] It can be understood that, with reference to Figures 1 to 7The utility model discloses first aspect embodiment's pot cover, including cover 100 and exhaust component 200, exhaust component 200, including mounting seat 210, rotatory block 220 and outer cover 230, mounting seat 210 is connected to cover 100, and mounting seat 210 is set up with exhaust passage 211, and exhaust passage 211 is communicated with the opposite sides of cover 100, and the gas outlet end of exhaust passage 211 is provided with gas outlet 212, and gas outlet 212 is set up in the lateral wall of mounting seat 210, and rotatory block 220 and outer cover 230 are successively sleeved in the upper end of mounting seat 210 from inside to outside, and outer cover 230 is fixedly sleeved in mounting seat 210, and the lateral wall of outer cover 230 is set up with first exhaust hole 231, and first exhaust hole 231 and gas outlet 212 are oppositely arranged, and rotatory block 220 is movably sleeved in mounting seat 210, and the lateral wall of rotatory block 220 is set up with second exhaust hole 221, and rotatory block 220 can rotate relative to mounting seat 210 to make gas outlet 212 can be communicated with first exhaust hole 231 through second exhaust hole 221.
[0033] When using, cover 100 is covered on the pot body 400, when needing high temperature and high pressure stewing food, by rotating rotatory block 220 to the position of second exhaust hole 221 and gas outlet 212 stagger, by the lateral wall of rotatory block 220 shielding gas outlet 212, can block the steam in exhaust passage 211 from first exhaust hole 231 and export, to make the pressure in the pot keep enough and stew, when needing to export the steam in pot body 400, because first exhaust hole 231 and gas outlet 212 are oppositely arranged, by rotating rotatory block 220 to the position of second exhaust hole 221 and gas outlet 212 alignment, make gas outlet 212 pass through second exhaust hole 221 and communicate with first exhaust hole 231, to make the steam in pot body 400 can pass through exhaust passage 211, second exhaust hole 221 and first exhaust hole 231 in proper order and export, thereby reduce the risk of spilling, therefore, can adjust the opening or closed state of exhaust according to the need, thereby improve the user's use experience. In addition, because first exhaust hole 231 is set up in the lateral wall of outer cover 230, make steam export from the lateral wall of outer cover 230, can reduce the possibility of steam scalding user, thereby improve the security of use.
[0034] It needs to be explained that by rotating rotatory block 220 to adjust the coincidence area of second exhaust hole 221 and first exhaust hole 231 or the coincidence area of second exhaust hole 221 and gas outlet, to adjust the conduction of steam, can control the discharge speed of steam, thereby improve the convenience of use.
[0035] When the mounting base 210 rotates, the outer cover 230 is fixedly sleeved on the mounting base 210, so that the outer cover 230 can rotate synchronously with the mounting base 210, thereby keeping the alignment state of the first exhaust hole 231 and the air outlet 212, improving the stability of adjustment, and adjusting the exhaust direction by rotating the mounting base 210 to drive the outer cover 230 to rotate.
[0036] The inner side wall of the rotating block 220 and the outer side wall of the mounting base 210 are fitted, which can improve the sealing between the rotating block 220 and the mounting base 210, and the inner side wall of the outer cover 230 and the outer side wall of the rotating block 220 are fitted, which can improve the sealing between the outer cover 230 and the rotating block 220, thereby reducing the possibility of water vapor leaking into the inner part of the outer cover 230 from the gap and being discharged from the first exhaust hole 231.
[0037] The cover body 100 can be a high-temperature-resistant piece such as a glass piece or a silica gel piece, which can reduce the possibility of deformation of the cover body 100 caused by high temperature and high pressure.

Since the knob 222 passes through the positioning groove 232 and extends out of the outer cover 230, the rotating block 220 can be conveniently rotated by poking the knob 222, thereby improving the convenience of adjustment.
[0039] It should be noted that the knob 222 can slide in the positioning groove 232, so that the rotating block 220 does not drive the outer cover 230 to rotate synchronously when the rotating block 220 rotates.
[0040] Specifically, referring to Figure 1 , Figure 5 and Figure 6The outer side wall of the mounting base 210 is provided with two limiting blocks 213, the two limiting blocks 213 are arranged at intervals along the circumference of the mounting base 210, a limiting groove 214 is formed between the two limiting blocks 213, the knob 222 is slidably embedded in the limiting groove 214, and the knob 222 can abut against the limiting blocks 213 to limit the rotation of the rotating block 220. Since the knob 222 is slidably embedded in the limiting groove 214, when the knob 222 is pushed, the knob 222 can slide in the limiting groove 214, when the knob 222 abuts against one of the limiting blocks 213, the second exhaust hole 221 and the first exhaust hole 231 are in a completely coincident state to realize the conduction of the first exhaust hole 231 and the air outlet 212, and when the knob 222 abuts against the other limiting block 213, the second exhaust hole 221 and the first exhaust hole 231 are in a completely staggered state to block the first exhaust hole 231 and the air outlet 212.
