The utility model relates to the technical field of electric pumps, in particular to an electric pump oil suction filtering structure not prone to blocking. The electric pump oil suction filtering structure not prone to blocking comprises a cylindrical oil suction hole located in an electric pump base and used for being connected with an oil suction pipe. The portion, close to the bottom, of the side wall of the cylindrical oil suction hole is provided with a filter screen installation hole communicated with the inner portion of an electric pump. A cylindrical filter screen matched with the filter screen installation hole and extending into the oil suction hole is arranged in the filter screen installation hole. Meshes of the filter screen are evenly distributed on the side wall of the filter screen and the bottom face of the filter screen. The cylindrical filter screen is adopted for the electric pump in the electric pump oil suction filtering structure, a traditional filter screen with one filtering face is
