Therefore, generally, the bottles are sterilized and disinfected by a sterilizing device. Existing bottles are generally sterilized by a liquid heater at high temperature, which boils the water in the liquid heater and sterilizes it with water vapor. However, the existing liquid heater generally only has the function of sterilizing the bottle with water vapor, and the function is relatively single.

[0003] Therefore, the applicant previously proposed a Chinese utility model patent authorization with publication number CN212729545U, "A Multifunctional Liquid Heater", which heats the water vapor heating component through a first heating component, thereby being able to heat or sterilize items in the water vapor heating component; and the water in the kettle placed on the outer shell can be heated through a second heating element.
