Embodiment Construction

[0018] The present invention will be further described now in conjunction with accompanying drawing.

[0019] like figure 1 and figure 2 As shown, its structure is as follows: 1-top cover, 2-outer orifice plate, 3-filter material, 4-inner orifice plate, 5-pipe joint, 6-connecting pipe, 7-sealing ring, 8-breathing port, 9 -rotating shaft, 10-spring, 11-lower barrel, 12-lower filter element, 13-float valve, 14-upper barrel, 15-microporous ceramic filter element, 16-warning device, 17-wire, 18-life water probe, 19 -middle barrel, 20-sealing ring, 21-working water probe, 22-water collection tank, 23-wire sealing joint. It can be seen that the upper barrel 14 is installed on the middle barrel 19, the middle barrel 19 is set on the lower barrel 11, and there is a sealing ring 7 therebetween. At the lower end of the middle barrel 19, the upper barrel 14 communicates with the middle barrel 19 through the microporous ceramic filter element 15, and the middle barrel 19 communicates ...

Abstract

The present invention is filter element life detecting method and device for drinking water purifier used in household and office. The drinking water purifier has structure comprising lower tub, middle tub and upper tub superposed successively, upper filter element in the bottom of the upper tub, and lower filter element in the lower part of the middle tub. The filter element life detection is completed with the water probe installed inside the middle tub and an alarm connected to the water probe. The water level inside the middle tub reflects the choking state of the lower filter element, and when the water probe inside the middle tub is immersed, it will send some signal and the alarm will process the signal to give out one acousto-optic prompt signal to show the status of the filter element.

Description

technical field [0001] The invention relates to a method and device for detecting the life of a filter element of a water purifier for domestic drinking water, and is particularly suitable for water purifiers in homes and offices. technical background [0002] The water in the upper barrel of the existing special water purifier for water dispensers enters the lower filter element after preliminary purification by the upper filter element, and then enters the lower barrel after being further processed by the lower filter element. There are currently two ways to judge the service life of the filter element. One is to set the use time, such as one year or eighteen months, when the time is up, the service life of the filter element is up. The second is to count the number of times the lid is opened and add water to estimate the amount of water added, that is, the net water volume of the filter element, so as to estimate the life of the filter element. It goes without saying th...
