Filtering device with automatic detection structure

Abstract

The invention discloses a filtering device with automatic detection structure, which comprises a filter cylinder provided with an opening end, a filter cylinder cover that is matched with the liquid in a sealing way, and a filter core arranged in the filter cylinder, wherein the filter core, the filter cylinder cover and the filter cylinder are matched with each other to form a water inlet chamber and a filtering chamber; the filter cylinder cover is provided with a water inlet hole communicated with the water inlet chamber, and a water outlet hole communicated with the filtering chamber; thetop of the filter cylinder cover is provided with a first plunger piston cavity communicated with the water inlet chamber, and a second plunger piston cavity communicated with the filtering chamber; the first plunger piston cavity is sealed by liquid and is assembled with a first plunger piston capable of moving up and down, and the second plunger piston cavity is correspondingly assembled with asecond plunger piston; and the first plunger piston and the second plunger piston are touched and matched with a lever taking a rotating shaft as a supporting point, and can drive the lever to trigger a microswitch for converting a pressure signal into an alarm signal. The invention can be used for detecting the working state of the filter core in real time and accurately judging the blocking situation of the filter core, and has the characteristics of stable working performance, simple structure, sensitive action and the like.

Description

technical field [0001] The invention relates to a water purifying device, in particular to a water purifying filter which needs to filter raw water through a filter core, in particular to a filtering device with an automatic detection structure. Background technique [0002] Household water purification equipment is a small water treatment equipment, which can effectively remove chlorine, heavy metal bacteria, viruses, algae and suspended solids in raw water. After that, activated carbon treatment will further remove various organic substances in the water, making the treatment The final 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 retained material and the ...

AI Technical Summary

Problems solved by technology

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 retained material and the reproduction of microorganisms, that is, the life of the filter element expires. In the past, it can only be judged according to the working time or the water flow rate. However, due to the different water quality conditions in various regions, Therefore, it is impossible to accurately detect the life of the filter element

The working status of the filter element cannot be understood and mastered in time, so it is not scientific enough, which brings certain hidden dangers to people's drinking water safety
