Abstract

The invention discloses a fuel filter. The fuel filter comprises a shell, a filter element and a combined sensor. The shell is provided with an oil inlet pipe and an oil outlet pipe. The filter element comprises saw-toothed folded tubular filter paper, an inner net, an upper cover plate and a lower cover plate. The inner net is inserted in the tubular filter paper and forms a filtering space. Theupper cover plate and the lower cover plate are fixed to the two ends of the tubular filter paper correspondingly. The upper cover plate is provided with a first through hole allowing the oil outlet pipe to communicate with the filtering space. The lower cover plate is provided with a second through hole allowing the combined sensor to be inserted in. An annular cavity is formed between the filterelement and the inner wall of the shell. The oil inlet pipe communicates with the cavity. The combined sensor is inserted in the lower end of the shell, extends into the filtering space through the second through hole and is used for sensing the fuel temperature in the filtering space and heating fuel in the filtering space. According to the fuel filter, mounting and dismounting operation of thefuel filter can be simplified, a circuit structure is simple, the strength, filtering precision and water separation efficiency are improved, the clogging capacity is increased, and thus the service life is prolonged.

Description

technical field [0001] The invention relates to the technical field of fuel filtration, in particular to a fuel filter. Background technique [0002] As a consumable part in auto parts, the market prospect of fuel filter is quite broad. Each sensor of the existing fuel filter is usually set independently, which is inconvenient to install and disassemble, and leads to complicated circuit structure. In addition, the filter element of the existing fuel filter is usually made of a single-layer material, resulting in low strength, easy to deform under the action of fuel flow pressure, and short service life, and the fuel filter made of a single-layer material The filtration accuracy, water separation efficiency and dust holding capacity are not high. Contents of the invention [0003] The main purpose of the present invention is to provide a fuel filter which is easy to assemble and disassemble. [0004] Another object of the present invention is to improve the filtration pr...
