A device and method for monitoring a water purifier

Abstract

The invention discloses a device for monitoring a water purifier, comprising a flow rate sensor and a residual chlorine probe for real-time monitoring of tap water and a water purifier by the monitoring device, collecting and sending water velocity information and residual chlorine information; a processor for receiving and monitoring The raw water velocity information at the water inlet of the water purifier collected by the flow velocity sensor in the device and the residual chlorine information collected by the residual chlorine probe, and the raw water velocity information and the pre-stored standard raw water velocity information and residual chlorine information are compared with the pre-stored standard raw water velocity information and residual chlorine information. The stored standard residual chlorine information is analyzed and compared, and the pre-stored command information matching the comparative analysis result is invoked and sent according to the comparative analysis result; the terminal device receives and displays the command information sent by the processor. The beneficial effect of the present invention is: it can more accurately reflect the real-time working status and real water production effect of each filter element of the water purifier, so that the household water purifier users will fully and effectively use the filter elements, and the use is reliable and convenient, which is beneficial to the market promotion and application.

Description

technical field [0001] The present invention relates to a monitoring device, in particular, to a device and method for monitoring a water purifier. Background technique [0002] In order to ensure the quality of purification in the existing household water purifier, the filter element needs to be replaced periodically, so as to ensure that the water purifier can produce qualified pure water. So, when should the filter be replaced? Calculating the true service life of the filter element is the core element. Since the life of the filter element is greatly affected by the quality of the raw water (tap water), and the quality of tap water varies greatly from place to place, it is necessary to monitor the real-time working state of the filter element and the quality of the pure water it outputs. In order to more accurately determine the individual life of the filter element. [0003] In the prior art, one type of filter element monitoring equipment is to monitor the service lif...

Problems solved by technology

[0005] For the first monitoring method, there are the following defects: the rated production water volume of the filter element is laboratory data, which is not accurate; secondly, the water quality of raw water (tap water) has a great influence on the service life of the filter element, and the water quality of tap water varies greatly from place to place. The service life of the filter element is not the same in different regions

[0006] As for the second monitoring method, there are also certain disadvantages: as mentioned above, the rated production water volume is laboratory data, and the average daily water consumption of households is also an estimated value; therefore, the rated production water volume and the daily average water consumption of each family The basic data is not accurate, and the rated service time calculated from it is also inaccurate
