That is, the exhaust valve 220 normally closes the exhaust passage by its own weight, and when the pressure in the pot body reaches a predetermined value (for example, when the exhaust valve 220 can be pushed up), the pressure in the pot body pushes up the exhaust valve 220 to open the exhaust passage.
The handle 300 is disposed on the pot lid 100, and at least a portion of the handle 300 is rotatable with respect to the pot lid 100. The exhaust button 400 is arranged on the pot cover 100 or the rotary handle 300, the exhaust button 400 is respectively linked with the exhaust valve 220 and the rotary handle 300, and the exhaust button 400 and the exhaust valve 220 are arranged on the pot cover 100 in a staggered mode.
The exhaust button 400 is pressed to drive the exhaust valve 220 to open the exhaust channel, the exhaust valve 220 can be restored to the state of blocking the exhaust channel when the exhaust button 400 is reset, the exhaust button 400 is kept at the current position through the retaining mechanism 500 after being pressed, and the exhaust button 400 can be driven to reset when the handle 300 rotates.
In other words, the degassing button 400 is pressed to open the degassing valve 220 and is maintained at the current position by the maintaining mechanism 500, and in particular, the degassing valve 220 is degassed after the degassing button 400 is pressed by the user, and the degassing can be continued without the user pressing the degassing button 400 all the time since the degassing button 400 is maintained at the current position by the maintaining mechanism 500. When the user operates the handle 300, the rotating portion of the handle 300 can reset the exhaust button 400 to close the exhaust valve 220.
According to the pot cover assembly 10 of the embodiment of the invention, the exhaust button 400 is arranged on the pot cover 100 or the handle 300, and the distance between the exhaust button 400 and the exhaust valve 220 is proper, so that scalding caused by high-temperature condensed water sprayed out by the exhaust valve 220 when the exhaust button 400 is pressed is avoided, and the situation that the user cannot cancel exhaust due to fear of scalding to cause continuous porridge overflow is avoided.
Moreover, by providing the holding mechanism 500, the position of the exhaust button 400 after being pressed is held by the holding mechanism 500, and the user can continuously exhaust without pressing the exhaust button 400, thereby avoiding fatigue of the user.
