However, the ball is loaded on the snorkel with its own weight. Although the ball will fall after the overheated vapor is leaked and then plug the upper end of the snorkel, the pressure difference between the inside and the outside of the pot causes the lid to be adsorbed on the pot. Because the pressure can not be balanced by external force, the pressure difference can be balanced. Therefore, it is only possible to apply a large force to the lid or use a swaying tool to remove the lid, which causes inconvenience in use.

According to the new patent of the Republic of China Patent Publication No. M338602, a "pot sealing structure" is disclosed, which includes a body, an elastic member and a valve body. After cooking the food, due to the valve body The pushing of the elastic element and sealing the vent hole is also caused by the pressure difference between the inside and the outside of the pot being adsorbed on the pot, although the pressure difference can be balanced by pushing the valve body through the tip, but when needed When the sharp object is lost due to loss or random littering, it is still necessary to apply a large force to the lid or use a swaying tool to remove the lid, which is still inconvenient in use.

The main object of the present invention is to solve the above problems and provide a valve body for a lid and a lid having the valve body, and the valve body is provided with a force to allow a through hole and a gas passage of the valve body.
