[0002] The disposable humidification tank on the market is generally made of high-transparent ABS or PC material, and if the humidifier used in conjunction, especially the high-flow respiratory therapy instrument, has a large heating power or unstable heating power in high-flow mode, the heating temperature is easy to exceed the set temperature. Especially in the state of dry burning of the humidification tank, the temperature of the heating disc will rise to more than 100 degrees, and the tank body connected thereto made of transparent ABS or other conventional materials cannot withstand deformation and other problems.
