Description

   filter   

The invention relates to a filtering device, in particular to a device capable of changing the pore density of a filter element of the filtering device.

The filter layer of a general filtering device has a fixed pore size to block the passage of impurities with a particle size larger than the pores in the water, but the impurities with a smaller particle size will pass through the pores with water. In the conventional filtering device, the water to be filtered needs to pass through several filtering layers with large to small pores in order to gradually filter out impurities in the water. If the water to be filtered passes directly through the smaller pores, Filter layer, excessive debris will quickly cause the filter layer to block, and reduce the service life of the filter layer.

However, the water quality is different in different regions, and the pollutants and impurities contained in water in different regions are also different. If the same several filter layers are used to filter water in various places, it may lead to the filtration of water debris in some regions. Incomplete, or lead to reduced service life of the filter device.

In view of this, the conventional filtering device still needs to be improved.
