[0022] 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.

[0023] As described in the background technology, the exhaust device of the current electric pressure cooker usually adopts an exhaust button transmission lever to drive the pressure relief valve to release pressure. However, since one end of the exhaust button pushes the lever, the exhaust button is subjected to the reaction force of the lever, which can easily cause the exhaust button to tilt, and the side wall of the exhaust button and the groove of the cover are very likely to get stuck, affecting normal exhaust and even causing air leakage.

[0024] To solve the above problems, see Figures 1 to 4 As shown, the present invention provides a pot cover, which includes a cover body 80 and an exhaust device arranged on the cover body 80, the cover body is provided with a cover tooth, the exhaust device includes a pressure relief valve 10, a transmission lever 20, an exhaust button 30 and a guide structure 40, wherein the pressure relief valve 10 is arranged on the cover body 80, and the pressure relief valve 10 has a pressure relief position that makes the two sides of the cover body 80 conductive, and a closed position that isolates the two sides of the cover body 80; the transmission lever 20 is rotatably arranged on the cover body 80, and the first end of the transmission lever 20 has a lifting position that lifts the pressure relief valve 10 to relieve pressure, and a avoidance position that avoids the pressure relief valve 10; the exhaust button 30 is movably arranged on the cover body 80, and a transmission column 31 is arranged at the bottom of the exhaust button 30, and the transmission column 31 is inserted into the clearance hole of the cover body 80, and the transmission column 31 is used to press the second end of the transmission lever 20; the guide structure 40 is arranged on the cover body 80 and is arranged around the clearance hole to guide the movement of the transmission column 31. Since the exhaust device of the pot cover of the present invention includes a guide structure, the guide structure is arranged on the cover body and around the give way hole to guide the movement of the transmission column, thereby avoiding the exhaust button from tilting and preventing the side wall of the exhaust button and the groove of the surface cover from getting stuck, so that the exhaust is normal.

[0025] See also Figure 3 and Figure 4 As shown, the guide structure 40 in this embodiment includes a first guide cylinder 41, which is arranged on the inner side of the cover body 80. The first guide cylinder 41 is coaxial and has the same diameter as the clearance hole, and the transmission column 31 is adapted to the inner wall of the first guide cylinder 41. When working, the transmission column 31 is guided by the first guide cylinder 41, so that the movement of the exhaust button is more accurate and the occurrence of jamming is avoided.

[0026] In order to provide a clearance space for the movement of the transmission lever, a clearance notch 411 is provided on the side wall of the first guide cylinder 41 in this embodiment, and the second end of the transmission lever 20 is inserted into the clearance notch 411. At the same time, the clearance notch 411 can also play a certain guiding role in the movement of the transmission lever.

[0027] See also Figure 3 As shown, the guide structure 40 in this embodiment further includes a second guide cylinder 42, which is disposed on the outside of the cover body 80. The second guide cylinder 42 is coaxial and codiametric with the clearance hole, and the transmission column 31 is adapted to the inner wall of the second guide cylinder 42. The movement of the transmission column 31 is further limited by the second guide cylinder, thereby more effectively ensuring the movement stability of the transmission column.

[0028] In order to further guide the movement of the exhaust button and at the same time improve the overall aesthetics of the pot cover, a countersunk hole 50 is provided on the cover body 80 in this embodiment, and a clearance hole is provided at the bottom of the countersunk hole 50. The exhaust button 30 is movably provided in the countersunk hole 50, and the exhaust button is guided and hidden by the countersunk hole 50.

[0029] Preferably, the outer wall of the exhaust button 30 in this embodiment is matched with the countersunk hole 50 , and the countersunk hole 50 can guide the movement of the exhaust button 30 .
