Abstract

The invention discloses a filter element service life monitoring method. The method comprises the following steps: acquiring a real-time water pressure difference value between a water inlet end and a water outlet end of a filter element; acquiring an instantaneous flow value of the water inlet end of the filter element and an accumulated flow value of the water inlet end of the filter element; calculating the ratio of the instantaneous flow value to the accumulated flow value of the filter element, calculating the product of the ratio and the real-time water pressure difference value of the filter element, and obtaining a first calculation value; and calculating a product of the first calculation value and a first preset life conversion parameter to obtain a first life value. The service life of the filter element can be accurately calculated, and the service life of the filter element can be prolonged according to the accurate service life of the filter element.

Description

technical field [0001] The invention belongs to the technical field of water purifiers, and in particular relates to a filter element life monitoring method and device and a water purifier. Background technique [0002] The water purifier can purify municipal tap water or other non-drinkable water sources through the internal filter element into pure water that can be directly drunk. Its core component is the filter element, and the service life of the filter element is closely related to the water quality of the raw water. The water quality of the raw water The better, the longer the working life of the filter element, the worse the raw water quality, the shorter the working life of the filter element. [0003] The life of the filter element of the existing water purifier is usually judged by the service time or flow rate of the filter element. However, this calculation cannot accurately calculate the life of the filter element, which will lead to the following problems: If...
