Abstract
A water-blocking and air-enterable structure includes a cup lid disposed with a direct drinking mouth assembly and a drinking nozzle assembly. The direct drinking mouth assembly includes a direct drinking mouth flap, a direct drinking mouth plug and an air inlet plug. The cup lid is provided with a spout and a first air inlet. The drinking nozzle assembly includes a drinking nozzle flap, a drinking nozzle seat, a drinking nozzle and an air inlet valve. The cup lid is provided with a second air inlet plugged by the air inlet valve, and a lower end of the drinking nozzle is connected with the air inlet valve through a plastic strip. The structure adopts two drinking-modes of using the direct drinking mouth assembly and the drinking nozzle assembly both being integral structures, the problems of loss of components, difficult assembly, and assembly dislocation can be avoided.
