Bagged water dispensers are divided into two types: upper water intake and lower water intake. The lower water intake has the best use experience and the most elegant operation (you don't need to manually poke a pipe in). However, the lower water intake equipment is more expensive, because it requires a more complicated and waterproof electric structure. This design and research is to make a water dispenser that can take water without an electric structure. The design was made many years ago, and the pictures made at that time were still gray and the colors were not very bright (≧ ﹤ ≦)
