Technical Field
[0001] The utility model belongs to the technical field of filters, and in particular relates to a multi-hole air intake device for filters. Background Art
[0002] A filter is a component that filters impurities and gases through filter paper. It typically refers to automotive filters, which are engine components. The oil filter is located in the engine lubrication system. It sits upstream of the oil pump and downstream of the various engine components that require lubrication. Its function is to remove harmful impurities from the oil drawn from the oil pan, supplying clean oil to moving parts such as the crankshaft, connecting rod, camshaft, supercharger, and piston rings, providing lubrication, cooling, and cleaning, thereby extending the life of these components.
[0003] Existing filters can only remove 60% of impurities in engine oil, resulting in low filtration efficiency. This is because existing oil filters rely on a single paper filter element to intercept and filter out harmful impurities in the oil. The smaller the pores in the filter paper, the better the filtration effect, but the lower the oil flow rate. The challenge is to find a way to filter out even the smallest impurities while allowing sufficient oil to pass through the same filter paper pores to supply the engine. Utility Model Content

[0007] Furthermore, the guide tube includes a cylinder, a guide column and guide blades. The two ends of the cylinder are connected. The guide column is arranged at the center of the cylinder. Multiple guide blades are connected between the cylinder and the guide column. The guide blades are arc-shaped, and the arc directions of the multiple guide blades are the same.
[0008] Furthermore, the guide unit and the plurality of guide holes on the guide plate are arranged in a matrix array.
[0009] Furthermore, the edge of the guide plate has a flange, one side of the flange is fixedly connected to the air inlet base opening, and the other side forms a flow channel with the air outlet shell opening, and the flow channel is connected to the dust exhaust port on the side of the air outlet shell.
[0010] Furthermore, the guide hole on the guide plate has a boss on the side facing the guide unit, and the boss is used to block the high-density powder layer in the inner cavity of the air inlet base, so as to be discharged through the dust exhaust hole on one side of the air inlet base.

The gas enters from the guide tube 12 at the upper end of the air inlet base 1 and is discharged from the air outlet 22 at the bottom of the air outlet shell 2. The dust and other impurities carried by the gas pass through the guide tube 12 to form a vortex. Dust particles with higher density are discharged through the dust outlet 13 on one side of the air inlet base 1, and dust particles with lower density pass through the guide plate 3 along the side wall of the air outlet shell 2 and are discharged from the dust outlet 21 between the guide plate 3 and the air outlet shell 2.
