Description

technical field [0001] The invention relates to a water purification system of a water purifier, in particular to a reverse osmosis water purification system with automatic water intake and drainage. Background technique [0002] With the continuous improvement of people's living standards, people pay more and more attention to the health of drinking water, so household water purifiers are widely used. The pressure storage tanks in existing water purifiers are all driven by air pressure, that is, one of the cavities is used for water in and out, and the other cavity is used for in and out of air. The cavity is filled with air, and the air squeezes the inner tank, so that the inner tank squeezes out the water. The pressure water storage tank of this structure only enters and exits water in one direction, and is driven by air, which has high energy consumption, less water in and out, and low efficiency. The air leaks and needs to be inflated. The operation is very troublesome...

Problems solved by technology

The pressure storage tanks in existing water purifiers are all driven by air pressure, that is, one cavity is used for water in and out, and the other cavity is used for in and out of air. When the water in the pressure tank is to be output, the air in and out must be The cavity is filled with air, and the air squeezes the inner tank, so that the inner tank squeezes out the water. The pressure water storage tank of this structure only enters and exits water in one direction, and is driven by air, which has high energy consumption, less water in and out, and low efficiency. Air leakage requires inflation, the operation is very troublesome, and electrical components such as motors or booster pumps are needed to drive the entire water purification system to work, the energy consumption is high, the structure is complicated, and the manufacturing cost is increased
