TDS water quality detection filter

Abstract

The invention provides a TDS water quality detection filter and belongs to the field of water treatment. The TDS water quality detection filter comprises a shell; a circuit board, an accumulator and aliquid crystal component are arranged on the exterior of the shell; the liquid crystal component is arranged on the circuit board; a water feeding channel, a water draining channel and a water passing chamber are arranged in the shell; the water passing chamber is used for communicating the water feeding channel and the water draining channel; a filter element is arranged in the water passing chamber; the filter element comprises a water outlet and a water inlet; the water inlet and the water outlet are respectively connected with the water passing chamber and the water draining channel; a tubular mounting part is integrally formed on an outer wall of the shell; a mounting plate is fixed in the mounting part; the inner chamber of the mounting part is divided by the mounting plate into a detection chamber and a sealing chamber which are not connected with each other; the detection chamber is connected with the water draining channel and directly faces the water outlet; two mounting holes are penetrated through the mounting plate along the axial direction of the mounting part; electrode bars are penetrated through the interior of the two mounting holes; one end of each electrode baris located in the water draining channel while the other end is electrically connected with the circuit board. The TDS water quality detection filter has the advantage of high detection precision.

Description

technical field [0001] The invention belongs to the field of water treatment and relates to a water filter, in particular to a TDS water quality detection filter. Background technique [0002] The pre-filter is usually installed after the water meter of the water inlet pipe to ensure that a large amount of precipitated impurities generated in the pipe network will not cause harm to the human body, and it plays a positive role in protecting the hidden pipes, faucets, electrical appliances, etc. [0003] In the prior art, the TDS water quality detection pen is generally used to detect the quality of the water filtered by the pre-filter, but there is a problem in this method: the drainage channel of the existing pre-filter has a certain length, and the detection pen detects The position is at the end of the drainage channel, that is to say, the water will be polluted by the drainage channel during the flow, which will affect the detection accuracy of the detection pen.
