System and method for detecting service life of filter element of water purifier

Abstract

The invention provides a system and a method for detecting the service life of a filter element of a water purifier, and relates to the technical field of water purifiers. The system for detecting the service life of the filter element of the water purifier comprises a low-pressure switch, a filter membrane device, a booster pump, a reverse osmosis (RO) membrane device, a flow meter, a high-pressure switch and a pressure barrel which are sequentially connected through pipelines. According to the invention, the maximum water production capacity of the filter element can be obtained by calculating the water production flow of the filter element at high frequency, and the attenuation of the water production capacity can be accurately calculated by comparing the maximum water production capacity every day with the water production capacity during delivery, so that the accurate service life of the filter element is obtained, and the service life of the filter element is prolonged by utilizing the accurate service life of the filter element. The filter element can be more accurately replaced for a customer, the service life of the filter element is not wasted, and the situation that use of the customer is affected due to blockage of the filter element is avoided, so that resources are utilized to the maximum extent, waste is avoided, and normal use of the user is not affected.

Description

technical field [0001] The invention relates to the technical field of water purifiers, in particular to a system and method for detecting the life of a filter element of a water purifier. Background technique [0002] The filter element is the core component of the water purifier. The quality and life of the filter element directly determine the water purification effect and service life of the water purifier. The filter element has a service life and needs to be maintained and replaced. [0003] At present, the industry mainly uses two methods to estimate the life of the filter element: time (use time) and water flow. For the same filter element, the water quality and frequency of use are different, which will lead to obvious differences in the life of the filter element. The above two methods are used. The calculation method of the filter element does not take into account the difference in water quality and the difference in the use of individual equipment, resulting in ...

[0003] At present, the industry mainly uses two methods to estimate the life of the filter element: time (use time) and water flow. For the same filter element, the water quality and frequency of use are different, which will lead to obvious differences in the life of the filter element. The above two methods are used. The calculation method of the filter element does not take into account the differences in water quality and the use of individual equipment, resulting in a rough calculation of the filter element, or the filter element has a long life, and the filter element is replaced in advance, resulting in a waste of filter element life; or the filter element is blocked, affecting the normal water consumption of users
