technical field

The utility model relates to the technical field of water purification equipment, in particular to a pure water machine.

Background technique

A pure water machine is a water purification device that purifies water. In the purification process, physical purification methods such as filtration, adsorption, and reverse osmosis without adding chemical substances are often used.

The filter system of the existing pure water machine mainly utilizes RO membrane (reverse osmosis membrane) to filter. With the help of the booster pump, the pressure of the water entering the pure water machine can be increased. When the high-pressure water passes through the RO membrane, the RO membrane will intercept impurities, heavy metals and other components in the water to ensure water molecules and minerals that are beneficial to the human body Ions, etc. can pass through, and then realize the function of purifying water.

In order to improve the taste of the water produced by the pure water machine, the filter system of the pure water machine is also equipped with an activated carbon filter element. The water filtered by the RO membrane will flow through the activated carbon filter element. Further adsorption is carried out to improve the taste of the water from the pure water machine.

However, since the activated carbon filter element is equipped with activated carbon, a large number of bacteria or viruses will grow in the activated carbon filter element after long-term use, and the long-term use of the water storage tank will cause the water quality of the pure water machine to decrease, thus affecting the water quality of the pure water machine.
