The inclined surface of the second wedge 411 abuts against the second magnetic element 2, so that when the first end 41 rotates towards the second magnetic element 2, the second magnetic element 2 is pushed from the first position to the second position. Referring to fig. 1, in this embodiment, specifically, the exhaust valve 10 is installed at the upper end of a valve core 11 of the pot cover, and a first support plate 12 is fixedly installed at the lower end of the valve core 11, and the first support plate 12 can be fixed on an inner cover of the pot cover; the second magnetic attraction piece 2 is annularly arranged and sleeved on the valve core 11; the first reset piece 3 is a compression spring sleeved on the valve core 11, and the upper end and the lower end of the first reset piece 3 are respectively connected with the second magnetic attraction piece 2 and the first supporting plate 12.
