Abstract

The invention discloses a household drinking water quality online detection device, relates to a water quality detection device, and aims to solve the problems that an existing water quality detection device is single in detection index and inflexible to disassemble, and online detection cannot be directly achieved in a pipeline. The household drinking water quality online detection device comprises a shell, a partition component, a flow guide pipe, a backflow pipe, an electrode detection sensor, a photoelectric detection sensor, a PLC (programmable logic controller) and a display, the upper end of the shell is a horizontal end, a water inlet is formed on end of the horizontal end, a water outlet is formed in the other end of the horizontal end, the partition component is arranged in the shell, the inside of the shell is divided into a first detection chamber, a flow guide chamber and a second detection chamber by the partition component, the electrode detection sensor is arranged in the first detection chamber, the photoelectric detection sensor is arranged in the second detection chamber, the electrode detection sensor and the photoelectric detection sensor are respectively connected with the PLC, and the PLC is connected with the display. The detection device is used for online detection of quality of household drinking water.

Description

technical field [0001] The invention relates to a water quality detection device, in particular to an online detection device for household drinking water quality. Background technique [0002] With the improvement of people's living standards, people's awareness of water quality and health continues to deepen, and people's requirements for water quality are also getting higher and higher. At present, there are many household water purification devices on the market. These devices can further treat tap water, but most of these products do not have water quality detection functions. Even if one or two of them are equipped with detection equipment, they only detect the conductivity, total dissolved solids The amount (TDS) and pH (pH) and other indicators, but the organic matter, chroma, turbidity and other landmark indicators in the water have not been tested, so the user has no way of grasping the water purification effect of the water purification equipment, and cannot know ...
