Research and development of a Practical Water Dispenser

The use of the boiled water of a constant temperature and a certain released amount is frequent in daily life, such as making milk with infant milk powder. However, the current water dispensers available in the market can only provide the single kind of fixed-temperature hot water or warm water or ice water and cannot provide the boiled water at the temperature and amount the users set as required; and the water filling could not be stopped automatically when the water overflows the cup, which is not convenient or practical and cannot satisfy the real needs of users. The Practical Water Dispenser adopts the 8052 Micro Controller Unit program control in the circuit design to control the water release time and flow rate of the high-temperature boiled water and low-temperature boiled water and mix the high-temperature boiled water with the low-temperature boiled water to achieve the boiled water at the temperature and amount required by users. At the same time, the original function of releasing water by pushing button is retained and a voice prompt is provided when the water filling action is completed. When the water from water dispenser overflows the cup, the water filling would be stopped automatically without water waste. It can actually achieve the purposes of convenient and practical use and water saving.
