Method for prompting replacement of filter material of filter and its apparatus

Abstract

The invention relates to a method for prompting replacement of a filter material of a filter and its apparatus, the method comprises the following steps: providing the filter, arranging a miniature current generator on a filter head of the filter; converting the generating amount to the current amount according to a corresponding relation of the generating amount of the miniature current generator and the water flow flowed through the filter head of the filter; finally comparing the above current amount with the threshold of the water flow flowed through the filter head of the filter; if the current amount is larger than the threshold of the water flow, the user is prompted to replace the filter material of the filter; if the current amount is not larger than the threshold of the water flow, prompting is not carried out. The method is easy to realize, a structure of the apparatus is simple. The miniature current is converted to the miniature electric current through the miniature current generator, the current amount is obtained according to the relation of the current amount and the electric current amount, the current amount is compared with the threshold of water flow flowed through the filter material of the filter, replacement of the filter material of the filter is prompted to the user; and the method is effectively guarantee the health of user for water usage.

Description

technical field [0001] The invention relates to a filter material replacement reminder method and device. Background technique [0002] As people pay more and more attention to water use in today's society, people pay more and more attention to the health of water use. Urban households generally use tap water for water use. The tap water is purified and disinfected by the tap water treatment plant and produced in accordance with the corresponding standards for people's living and production use. Filtration and other technological processes are finally transported to various users through the water distribution pump station. [0003] Because the tap water has undergone multiple treatments, the tap water contains more impurities, so household water generally installs a filter on the water outlet of the faucet or water heater to filter out the impurities in the water. [0004] However, because people don't pay enough attention to the filter, they think that just installing a ...

Problems solved by technology

[0004] However, because people don't pay enough attention to the filter, they think that just installing a filter can purify water, but they don't know that the filter is prone to damage after long-term use, and it can't achieve the function of filtering out impurities in water; for This requires a method and a device to remind the user to replace the filter material in time
