Description

Technical Field

[0001] The invention relates to the technical field of dust removal of fuel connectors, in particular to a dust removal device for an automobile fuel filter. Background Art

[0002] A dust removal device for an automobile fuel filter is a device for removing impurities from fuel and improving the relative purity of fuel. The function of the fuel filter is to remove solid impurities such as iron oxide and dust contained in the fuel, prevent the fuel system from being blocked (especially the fuel injector), reduce mechanical wear, ensure stable operation of the engine, and improve reliability. It is widely used in the automotive field. The fuel filter is mainly composed of a shell, replaceable filter paper, replaceable magnetic material and a filter screen. Its working principle is to use bolts and nuts to closely contact the first fixing plate with the shell and seal it through a sealing ring to ensure sealing. When it is necessary to replace the replaceable filter paper and the replaceable magnetic material, the bolts and nuts are loosened, the first cover plate is removed, and the replaceable magnetic material adsorption box is taken out by pulling the limit block. When the first support block loses support for the first fixing plate, the first fixing plate is removed and the filter paper is replaced.

[0003] Most existing fuel filters are one-time replacement devices. When a certain mileage is reached, they are directly replaced, which increases the cost of use. In addition, the internal filter paper cannot be replaced, so the only option is to purchase the finished product, which not only increases the cost of use but also causes a waste of resources.
