Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative efforts all belong to the protection scope of the present invention.

Referring to fig. 1-2, the present invention provides a technical solution: the fuel filter with the double-hydrophobic structure comprises an outer shell 1, wherein a filter element main body 2 is installed inside the outer shell 1, an annular fixed seat 3 is installed inside the bottom end of the outer shell 1, a hydrophobic cover 4 is installed at the top of the annular fixed seat 3, the hydrophobic cover 4 is sleeved on the surface of the filter element main body 2, a water receiving groove which is distributed annularly is further formed in the top of the annular fixed seat 3, a drain pipe 5 is installed on the inner wall of the bottom of the water receiving groove, and a drain valve 6 is installed on the drain pipe 5;
