Problems solved by technology

[0003] At present, the coarse filter and the fine filter on the oil filling pipe assembly are two independent parts. In the actual use process, it is found that the two filters of the traditional independent design have the following disadvantages: 1. The independent design not only has high production and purchase costs, but also And it takes up a lot of space; 2. The two filters are independent and non-removable as a whole, and the internal filter element cannot be replaced. As time goes by, more and more dust accumulates inside, and the ventilation is not smooth, which seriously affects the normal operation of the fuel pipe assembly. 3. The traditional two filters are connected to the pipeline by cold crimping, even if you want to replace the entire filter, you cannot replace it

Abstract

The invention discloses a detachable integrated air filter and belongs to the technical field of tools for motor vehicles, aiming at solving the problems that traditional coarse filters and fine filters are of independent type structures, so that a large space is occupied and the filters are difficult to maintain and repair. The detachable integrated air filter mainly comprises a shell body, an end cover provided with an air vent, a fine filter element, a fine filter element tray, a coarse filter element and a sealing cover which is fixedly connected with the shell body and is provided with a male connector annular lug boss. The detachable integrated air filter provided by the invention is integrated and detachable, has the advantages of small occupied space, low manufacturing cost, long service life and very strong practicability and can be widely applied to the technical field of automobile air filters.

Description

technical field [0001] The invention belongs to the technical field of motor vehicle appliances, and in particular relates to a detachable integrated air filter. Background technique [0002] Cars are an indispensable means of transportation in people's lives. As cars become more and more popular in the market, people pay more attention to the service life of cars. As a tool, longer trouble-free working time and less maintenance frequency are what every consumer expects. When the car is working, the external air enters the fuel tank through the coarse filter and the fine filter. The two filters are mainly used to filter the dust that enters the vent pipe from the external air; [0003] At present, the coarse filter and the fine filter on the oil filling pipe assembly are two independent parts. In the actual use process, it is found that the two filters of the traditional independent design have the following disadvantages: 1. The independent design not only has high product...
