Fuel filter

Abstract

According to the technical scheme of the invention, a fuel filter comprises a shell, the two axial ends of the shell are provided with a fuel inlet and a fuel outlet correspondingly, and a fuel inlet pipe and a fuel outlet pipe are fixed to the position of the fuel inlet and the position of the fuel outlet correspondingly. The fuel filter is characterized in that a sleeve is arranged on the outer surface of the shell; an insertion groove is formed in the inner wall of the sleeve; an installation assembly capable of being inserted in the insertion groove is arranged on the outer surface of the shell; a sleeve fixing block is arranged on the outer surface of the sleeve; an installation frame detachably connected with the sleeve fixing block is arranged on the sleeve fixing block; the shell is internally connected with an inner baffle so that the shell and the inner baffle can be promoted to form a cavity; the inner baffle and the shell are concentric cylinders; two partition plates are fixedly connected to the inner baffle; the cavity between the inner baffle and the shell is divided by the partition plates into three containing cavities; and filtering stone, filtering sand and filtering cotton are sequentially arranged in the three containing cavities correspondingly.

Description

technical field [0001] The invention relates to an automobile accessory, in particular to a fuel filter. Background technique [0002] The function of the fuel filter is to filter out the water and impurities in the fuel. When the engine is working, the fuel enters the sedimentation cup of the filter through the oil inlet pipe under the action of the gasoline pump. As the volume becomes larger and the flow rate becomes smaller at this time, water and impurity particles heavier than oil settle at the bottom of the cup, light impurities flow to the filter element with the fuel, and clean fuel seeps into the filter element from the micropores of the filter element, and then out through the tubing. [0003] The traditional filter includes a shell, one axial end of the shell is provided with an end cover, the other end is provided with an oil outlet, the end cover is provided with an oil inlet, and a filter chamber is provided between the oil inlet and the oil outlet. , There ...

AI Technical Summary

Problems solved by technology

The oil inlet and the oil outlet of the filter are respectively provided with an oil outlet pipe and an oil inlet pipe. There are still some defects in the current fuel filter: 1. The filter is generally installed at the bottom of the vehicle. , there will be stones hitting the filter, which will cause damage to the filter; 2. During the installation process, the filter is connected to the fuel tank through the installation bracket. Due to different models, the installation space is different, so different Vehicle models must use different types of mounting brackets, which will result in high production costs. 3. The filter element of the current filter is generally filter paper, and the service life is low, so the filter needs to be replaced frequently
