When the pressure of the electric cooker is not increased, the pressure limiting elastic piece 200 is pressed on the second air outlet hole 109 of the micro-pressure valve seat 5, so that the second air outlet hole 109 of the micro-pressure valve seat 5 is closed. Steam is continuously generated when the electric cooker works, so that pressure is generated in the electric cooker. The micro-pressure valve cover 4 and the micro-pressure valve seat 5 are connected by means of sealing ring, ultrasonic welding, heat sealing and the like to prevent steam from leaking between the micro-pressure valve cover 4 and the micro-pressure valve seat 5. The material of the micro-pressure valve cover 4 can be a resin polymer material such as PP or a material such as silica gel and metal. In particular, when the material of the micro-pressure valve cover 4 is a soft rubber material such as silica gel, the micro-pressure valve cover 4 and the micro-pressure valve seat 5 can be directly sealed by pressing, without the need to adopt the connection mode of sealing ring, ultrasonic welding, heat sealing and the like, thereby further saving cost. The pressure limiting elastic piece 200 is in abutment with the micro-pressure valve seat 5, so that the second air outlet hole 109 is closed and cannot exhaust. Only when the pressure in the electric cooker exceeds the elastic force of the pressure limiting elastic piece 200, the pressure limiting elastic piece 200 is lifted and deformed to open the second air outlet hole 109, and steam is exhausted from the second air outlet hole 112.
