Water system with composite filter core, and calculation method for service life of composite filter core

Abstract

The invention relates to a water system with a composite filter core. The water system comprises a water way which comprises a water inlet end and a water outlet end. The water system is characterized by further comprising a flow acquisition element, the composite filter core and an electric control device, wherein the electric control device is electrically connected with the flow acquisition element. According to the water system, the electric control device calculates the rest service life of the composite filter core according to received water flow signals and stores the calculated value of the rest service life in the electric control device, so a user can conveniently learn about the condition about the service life of the composite filter core in real time and replace the composite filter core in time; and thus, it is guaranteed that water drunk by the user is sanitary and safe, and cost increase caused by too early replacement of the filter core is prevented. The scheme in the invention is easy to implement. The invention also discloses a calculation method for the service life of the composite filter core. The method is easy to implement and accurate in service life calculation.

Description

technical field [0001] The invention relates to a water system, in particular to a water system with a composite filter core and a calculation method for the life of the composite filter core. Background technique [0002] Existing water systems, especially water filtration (purification) systems, such as: water purifiers, water is filtered through one or more layers, and then discharged from the water outlet for drinking by users; however, the above-mentioned traditional water systems are still There are the following deficiencies: (1) The user cannot know the use status of the composite filter element in real time, let alone replace the filter element in time. If the filter element is replaced too early, it will cause waste and increase the user's use cost. If the filter element is replaced too late, the user will drink too much Unclean water. Contents of the invention [0003] The purpose of the present invention is to overcome the shortcomings of the above-mentioned p...
