Technical Field
The invention relates to the technical field of dust collection, in particular to a filtering assembly and a dust collector.
Background
Along with the improvement of people's standard of living, it is more and more higher to the clean environment on every side, especially in the family is clean, needs carry out thorough cleanness to the inside dirt of house, but can not satisfy indoor cleanliness through traditional mode, and waste time and energy moreover, and the dirt and the filth in the clean room that the dust catcher can be effective and quick satisfy people's requirement. Therefore, it is widely used.
Generally, a vacuum cleaner includes a motor device for driving an external air to flow into a separator, and the separator separates dust in an air flow and discharges clean air. And, the air-out side that corresponds motor device in the dust catcher is provided with filtering component to filter the air that flows by motor device, filtering component uses after a period, inside deposition, and the windage increases, needs wash filtering component this moment, avoids the windage too big and influence the efficiency of breathing in of dust catcher. However, if the user washs filtering component and can not influence the use of dust catcher in time, if the user washs filtering component often, filtering component can reduce along with abluent number of times increase filter effect, and filtering component's life is shorter. Thus, the user cannot clean the filter assembly when necessary.
