Abstract

The present invention discloses a water purifier filtration core service life detection apparatus, which comprises: N filtration cores sequentially connected in a series, wherein N is an integer of greater than or equal to1; valves, wherein the inlet of the valve is respectively connected with the first end of the N filtration cores and the second end of the Nth filtration core; a detection module connected with the outlet of the valves and provided for detecting pressures of the first end and the second end of each filtration core so as to produce corresponding pressure detection signals; and a control module for controlling the valve so as to select the corresponding filtration core, acquiring the pressure difference value of the corresponding both filtration core ends according to the pressure detection signal, comparing the pressure difference values of both ends of each filtration core with a corresponding preset threshold, and judging whether the failure of each filtration core exists according to the comparing result. The water purifier filtration core service life detection apparatus has characteristics of high detection precision, cost saving, simplified control complexity, and improved reliability. The present invention further discloses a detection method of the water purifier filtration core service life detection apparatus.

Description

technical field [0001] The invention relates to the technical field of water purifiers, in particular to a detection device for the life of a filter element of a water purifier and a detection method for the detection device for the life of a filter element of a water purifier. Background technique [0002] At present, filters and filter elements are widely used to remove chlorine, heavy metal bacteria, viruses, algae and suspended solids in raw water, so that the treated water is clear, clean and sterile, and can provide people with healthy and standard drinking water. Household water purification equipment generally consists of multiple sets of filter devices with filter elements with different functions. However, after the filter element is used for a long time, it will cause the filter element to fail due to the blockage of the retentate and the proliferation of microorganisms, that is, the life of the filter element expires. The existing technology can only judge whethe...
