Description

Filter element structure

Technical Field

The utility model relates to the field of filter elements of water purifiers.

Background

As the water yield of the filter element in the water purification industry, particularly the shell of the RO membrane filter element increases along with the increase of the RO membrane water yield, the size of the shell is larger, from 50G to 1000G, and along with the diameter increase, the pressure bearing performance of the filter element has higher and higher requirements on the structural design of the shell of the filter element. Because the traditional small RO membrane shell mainly comprises a filter flask and an end cover, the disposable filter element is in a spin-melting mode. The rotary melting is to melt the plastic of the contact surface instantly by two friction pieces which rotate at a high speed and press down at the circumferential end face, the plastic is cooled and solidified, finally the filter bottle and the end cover are sealed into a whole and bear a certain pressure, but the diameter of the filter bottle is increased from the minimum to the maximum along with the increase of the diameter size, the circular projection area is increased by 4-5 times, the larger the size is determined by the limitation of the rotary melting process, the lower the qualified rate of the finished product is (the wall thickness of the filter bottle cannot be increased without limitation, otherwise the injection molding process and the appearance requirements cannot be met.

In this regard, there is a need for improvements in the prior art.
