In the context of the significant improvement of people's material living standards, people are paying more and more attention to dietary health, especially the health of drinking water. Many people improve the quality of drinking water by installing water purifiers. However, most residents need hot water for drinking, and water purifiers cannot meet this requirement. The existing water dispenser generally has a heating function, but also has a temperature display function. Although heating and automatic power-off can be performed during use, personnel cannot intervene in the cycle process, so there are many defects. Based on this background, this paper designs a smart water dispenser system. Based on this system, it can realize rich functions such as voice broadcast, temperature detection, OLED display, motor water outlet, temperature setting, WIFI remote control, etc. The manual control can also be performed remotely through the APP, and the display interface information is more intuitive, which is convenient for people to use the smart water dispenser for heating and remote control. The designed intelligent water dispenser system is easy to operate, cost-effective, and has high practical value.
