Description

filter

The present invention relates to a filtering device, and more particularly to a pore density that can change the filter element of the filtering device.

The filter layer of a typical filter device has a fixed pore size to block the passage of impurities having a particle size larger than the pores in the water, but the smaller particle size will pass through the pore together with the water. In the conventional filtering device, the water to be filtered needs to pass through a plurality of filter layers from large to small pores in order to filter the impurities in the water step by step, if the water to be filtered passes directly through the pores. In the filter layer, excessive debris will quickly block the filter layer and reduce the service life of the filter layer.

However, the water quality varies from region to region. The waters in different regions contain different pollutants and impurities. If the same filter layer is used to filter the water, it may cause water contamination in some areas. Incomplete, or a situation in which the life of the filter device is reduced.

In view of this, the conventional filtering device does have a need for improvement.

In order to solve the above problems, the object of the present invention is to provide a filtering device whose filter element can adjust the pore density as needed.
