Background At present, when a liquid heating container such as a humidifier, an electric cooker, a health preserving kettle and the like works, internal liquid is required to be continuously heated, and as the temperature of the liquid rises, moisture is continuously vaporized into steam, so that the pressure in the container main body continuously rises. In order to ensure that the liquid heating containers can safely, stably and efficiently operate, steam generated in the main body needs to be timely discharged to the external environment from the air outlet, so that the balance of the pressure inside the containers is maintained. However, when people use the liquid heating container and knock down carelessly, a water leakage preventing structure is generally arranged in the liquid heating container, and the water leakage preventing structure not only seals water flow and water vapor in the water tank, so that the water flow and the water vapor in the water tank are discharged to the outside. The poured liquid heating container is continuously heated, and after the pouring is powered off, waste heat is also generated, so that steam is continuously produced in the liquid heating container. However, the water leakage preventing structure always seals the steam outlet, so that the internal pressure of the liquid heating container is continuously increased.
