Description

Probe installation structure and water purifier for TDS on-line detection

technical field

The disclosure relates to the field of TDS detection, in particular to a probe installation structure for TDS online detection and a water purifier.

Background technique

TDS is the abbreviation of total dissolved solids in English. The Chinese translation is total dissolved solids. The measurement unit is mg/L (mg/L). It indicates how many mg of total dissolved solids are dissolved in 1 liter of water. The TDS value represents the impurity content of dissolved substances in the water. The larger the TDS value, the greater the impurity content in the water, and vice versa, the smaller the impurity content.

In response to the needs of consumers, more and more household water purifiers have begun to add the TDS online detection function to realize real-time monitoring of the water quality of the water purifier. Most of the TDS probes are installed by connecting a tee joint in series in the waterway. Two of the three interfaces of the tee joint are connected to the water inlet and outlet of the waterway, and the remaining interfaces are installed with TDS probes. Measure the TDS of the water flowing through it.

The TDS probe inserted into the tee joint interface narrows the water path flowing through the tee joint, resulting in an acceleration of the water flow through the TDS probe, and the acceleration of the water flow makes the test results difficult to stabilize. In addition, the blocking effect of the TDS probe on the water flow makes the water flow impact the probe position of the TDS probe to form air bubbles, and the air bubbles between the probe electrodes change the density of the water, which greatly affects the conductivity between the electrodes, and finally makes the TDS test The result is a serious error.
