Abstract
The invention provides a pressure-adjustment exhausting safety valve of an electric pressure cooker. The safety valve comprises a valve element, a valve deck and a valve seat. The valve seat is connected with the valve deck through threads. An anti-blocking nut downwards extends to form a cylindrical cavity in a connected mode. Air holes are formed in the periphery and the bottom of the cavity. A valve seat air flow channel is formed in a valve seat shell. An iron core and an electromagnet are arranged in an inner cavity of the valve seat shell. An elastic element is arranged between the iron core and the electromagnet. The outer surface of the electromagnet is wrapped by a sealing piece made of flexible materials. A valve element rod penetrates through the valve deck, the elastic element, the electromagnet, the bottom of the valve seat shell, the sealing piece and the upper portion of the anti-blocking nut and can vertically move. An air inlet hole and an air outlet hole are formed in the valve element rod, and the height of the air inlet hole and the height of the air outlet hole adapt to the height of the valve seat air flow channel and the height of the inner cavity of the anti-blocking nut. A heating device can be further stopped while a control circuit of the electric pressure cooker loses efficacy, the pressure of air in the cooker exceeds a set value, and automatic and safe pressure releasing is carried out; in addition, the safety valve has the advantages of being simple in structure, convenient to use and the like.
