Filtering apparatus, water purifier and filtering apparatus use method

The invention discloses a filtering apparatus, a water purifier and a filtering apparatus use method. The filtering apparatus comprises a filtering core and an ultrasonic wave cleaning assembly, wherein the ultrasonic wave cleaning assembly is used for cleaning the filtering core, and comprises a plurality of independently working ultrasonic wave generating sections sequentially distributed alongthe length direction of the filtering core. According to the present invention, the cleaning mode of the present invention is different from the existing cleaning mode, the filtering core is cleaned through multi-section ultrasonic waves, and each part of the filtering core can be cleaned in a targeted manner, such that the cleaning effect is superior to the cleaning effect of the existing cleaning mode, and the filtering core cannot be damaged. 本发明公开了种过滤装置、净水机及过滤装置使用方法，过滤装置包括滤芯和超声波清洗组件；超声波清洗组件用于清洗滤芯，超声波清洗组件包括多个沿滤芯的长度方向依次分布且独立工作的超声波发生段。本发明区别于现有的清洗方式，通过多段式超声波对滤芯进行清洗，可以对滤芯的各个部分进行针对性清洗，不仅清洗效果优于现有的清洗方式，而且不会损坏滤芯。
