An air admittance valve preventing mephitis overflow, having a main body with an air entry guide base defining an air entry guide; a pivot support; and a valve seat. A sealing valve group having a sealing valve body that defines a recess; a flexible member; a pivot housing; and a pivot. The valve seat is located about the air entry guide. The pivot is located in the pivot housing and the pivot support, and the pivot is located along, or adjacent to, the center of gravity of the sealing valve body. The flexible member is at least partially located in the recess and abuts the main body; and when the air admittance valve is closed, the sealing valve body abuts the valve seat.

A wash basin drain structure includes a tightening assembly, a control rod assembly, a drain pipe, and a plug. A threaded top ring of the fastening assembly relative to a threaded annular seat is screwed reversely to push an anti-leakage washer of the drain pipe upward, so that the threaded top ring and a washer are against the bottom of the wash basin and resilient portions of the resilient ring engages with a non-slip portion of the drain pipe. When a threaded fixing member in a threaded hole of a fixing seat of the control rod assembly is screwed inward, the end of the threaded fixing member will hold against the body of the drain pipe and pull an inner pipe portion of the fixing seat to seal and engage with an insertion hole of the drain pipe. A magnetic end head of a link rod of the control rod assembly is attracted to connect with a magnetic portion of a plug body of the plug to act as a lever. The present invention can be assembled with ease.

A cooking device having an outer pot and an inner pot removally suspended in the outer pot is proposed for better and easier cooking of foodstuff. The inner pot is made of thermally conductive, metallic material and is adapted for initially cooking foodstuff with a separate heater for a short period of time. The outer pot is made into a thermally insulated construction and adapted to house the inner pot containing the semi-cooked foodstuff in the outer pot in a thermally insulated manner, so as to allow the semi-cooked foodstuff to complete the cooking by its own latent heat without a further heating by an external heat supply means.
