Detailed Description

The following describes embodiments of the present invention with reference to the drawings.

As shown in fig. 1-3, the high efficiency filter of the present embodiment includes a filter assembly, and the structure of the filter assembly is: the filter screen cotton cylinder is characterized by comprising a filter screen cotton cylinder body 2, wherein a liquid inflow cavity 8 is formed in the middle of the filter screen cotton cylinder body, a layer of filter screen cloth 3 is arranged on the inner wall of the liquid inflow cavity 8, the bottom surface of the filter screen cotton cylinder body 2 is sealed by a lower cover 1, a connector 6 is arranged on the top surface of the filter screen cotton cylinder body through an upper cover 4, a suction pipe channel for penetrating a liquid suction pipe 7 is axially arranged in the connector 6, and the suction pipe channel is communicated with; the joint 6 positioned at the outer ring of the orifice of the suction pipe passage is provided with a retractable cross groove 61, and when the liquid suction pipe 7 is inserted into the suction pipe passage from the center of the cross groove 61, the joint 6 deforms and holds the liquid suction pipe 7 tightly.
