Water yield and water quality monitoring alarm for pure water machine

Abstract

The invention relates to a pure water machine, in particular to a water yield and water quality monitoring alarm for the pure water machine, and belongs to the fluid on-line detection technical field of flow monitoring, conductivity monitoring and alarming. A water yield detection circuit is composed by connection between a normal close end of a high voltage switch and a signal collecting end of a microcontroller unit (MCU); a select switch of conductivity alarming value indicated by total dissolved solids (TDS) is connected with the MCU; a water yield data reset switch is connected with the MCU; a sound alarming device and a display device are connected with the MCU to form an alarming circuit which has functions of real-time monitoring and alarming of water quality and sound prompt for filter element renewal. The water yield and water quality monitoring alarm has advantages that the product structure is simple, the cost is low, the installation is convenient, the monitoring is accurate; complex setting and operation by users are not needed; users can be informed of the working condition of the pure water machine in time, and be warned to change the filter element and a reverse osmosis membrane; and sanitation safety of drinking water of users is well guaranteed.

Description

technical field [0001] The invention relates to a pure water machine, which belongs to the technical field of fluid on-line detection of flow monitoring, conductivity monitoring and alarming. Volume, value for sound warning and display alarm. Background technique [0002] Now the monitoring of the water quality of the water produced by the pure water machine is generally carried out by using a TDS pen-shaped detector or installing a conductivity meter. The installation of a conductivity meter is expensive and cumbersome to install. It only has a display function and no sound prompts. , people drinking pure water produced by pure water machines cannot be guaranteed safe. Real-time monitoring of water quality and reminders for filter element replacement are the basic needs of users of pure water machines. The conductivity of pure water also varies greatly. It is necessary to monitor the conductivity of the pure water produced by the pure water machine. The installation of mon...

[0002] Now the monitoring of the water quality of the water produced by the pure water machine is generally carried out by using a TDS pen-shaped detector or installing a conductivity meter. The installation of a conductivity meter is expensive and cumbersome to install. It only has a display function and no sound prompts. , people drinking pure water produced by pure water machines cannot be guaranteed safe. Real-time monitoring of water quality and reminders for filter element replacement are the basic needs of users of pure water machines. The conductivity of pure water also varies greatly. It is necessary to monitor the conductivity of the pure water produced by the pure water machine. The installation of monitoring devices is scattered, the settings are cumbersome, and various connections are complicated. Functions such as filter element replacement reminders cannot be widely used, which in turn affects the popularity of pure water machines
