Determination method of service life of filter core in water purifying system and the water purifying system

Abstract

The invention provides a determination method of service life of a filter core in a water purifying system and the water purifying system. In the method, use times and flow rate values of different filter cores are considered at the same time. The system also has an alarm reminding function, so that a user can conveniently know when the filter core in a water purifier of the user needs to change and which filter core needs to change, thus reducing cost and improving purifying effect. TDS detection sensors are arranged respectively on the front and rear ends of a RO membrane filter core, wherein RO water production rate and water quality TDS influence proportion are introduced as correction factor, service life of the filter core is further accurately calculated, especially the service lifeof the filter core of the RO membrane.

Description

technical field [0001] The invention relates to the technical field of water purification, in particular to a method for confirming the service life of a filter element of a water purification system and a water purification system using the method to confirm the service life of the filter element. Background technique [0002] With the increasingly serious pollution of water resources, water purifiers have been widely used, and the reverse osmosis water purifier with the best filtering effect has been favored unprecedentedly. However, the replacement frequency of the filter elements of the water purifiers currently on the market is set according to empirical values, without taking into account the user's frequency of use and the local water quality, which is very unreasonable, and generally used in water purifiers Multiple filter elements, different filter elements have different materials, have different filtering effects, and also have different life spans. Therefore, a m...

However, the replacement frequency of the filter elements of the water purifiers currently on the market is set according to empirical values, without taking into account the user's frequency of use and the local water quality, which is very unreasonable, and generally used in water purifiers Multiple filter elements, different filter elements have different materials, have different filtering effects, and also have different life spans. Therefore, a more reasonable calculation method for filter element life is needed, and it has the function of automatic prompting, so that users can easily know what they are using. When does the water purifier need to replace the filter element, or which filter element needs to be replaced
