Drinking water filter intelligent management device

Abstract

The invention provides an intelligent management device for drinking water filter elements. The intelligent management device comprises a flow sensor input end, a first pulse presetting circuit and a first counting and comparing unit, wherein the flow sensor input end is used for receiving a first pulse signal which is output by a flow sensor and is used for representing water production flow; the first pulse presetting circuit is used for presetting a first pulse number, and comprises a plurality of first toggle switches; and the first counting and comparing unit is used for generating a filter element replacement alarm signal when the count number of the first pulse signal reaches the first pulse number. According to the intelligent management device, the water filtering life (namely the first pulse number) of each stage of filter element can be set through the first toggle switches according to different source water quality, so that the grouping management of the filter elements is achieved; the intelligent management device has the characteristics of simple structure and low cost; and according to the difference of source water quality, different filter element replacement time can be set and corresponding filter element replacement alarm signals are sent out, and thus a user is reminded of timely replacing the filter element.

Description

technical field [0001] The invention relates to the field of water dispensers, in particular to an intelligent management device for drinking water filter elements. Background technique [0002] Most of the water purifiers and pure water machines currently on the market are simple water-making equipment, and their filter elements have no management circuit. The total water production capacity of the filter element cannot be displayed, and the amount of water filtered by the filter element needs to be replaced, and it is impossible to know, which is extremely inconvenient to use. The filter elements of water purifiers and pure water machines have reached the end of their service life. If they are not replaced in time, they will cause secondary pollution to the water quality and endanger human health. Although some water purifiers and pure water machines on the market have realized filter core management, most of them manage the filter core regularly through water switches. T...

Problems solved by technology

The total water production volume of the filter element cannot be displayed, and it is impossible to know how much water the filter element needs to be replaced. It is extremely inconvenient to use

The filter elements of water purifiers and pure water machines have reached the end of their service life. If they are not replaced in time, they will cause secondary pollution to the water quality and endanger human health.

At present, although some water purifiers and pure water machines on the market have realized the management of the filter element, most of them manage the filter element regularly through the flow switch. This kind of management is very unscientific. The present invention overcomes the above-mentioned disadvantages
