A dual-purpose combined filter

Abstract

The invention discloses a dual-purpose combined filter. The filter comprises a shell and a filter element; the filter element comprises an upper end cover, a lower end cover, a first mounting ring, asecond mounting ring and a filtering body; the upper end cover is connected with an upper shell body through the first mounting ring, the lower end cover is connected with a lower shell body through the second mounting ring, the filtering body is clamped between the upper end cover and the lower end cover, and four layers of retaining rings are correspondingly arranged on the upper end cover and the lower end cover from outside to inside respectively and separate the filtering body. The dual-purpose combined filter can be used as an air filter and an air conditioner filter, and the product versatility is high; a manufacturer can produce the air filter and the air conditioner filter through one production line, and the production cost is greatly reduced; multiple retaining rings are adoptedfor locating the filtering body, the filtering body is prevented from displacement and deformation, the service life of the filtering body is prolonged, and the use cost of the filter is reduced; theupper and lower end covers are connected to the shell, the end covers do not need to be taken out along with the filtering body during disassembly, and the disassembly is convenient.

Description

technical field [0001] The invention relates to the technical field of auto parts, in particular to a dual-purpose combined filter. Background technique [0002] Filters can be divided into oil filters, fuel filters, air filters and air conditioner filters according to their functions, which are respectively responsible for the lubrication system, combustion system, engine intake system and air circulation system in the car. Filtration is beneficial to prolong the service life of various components in the car engine, efficiently utilize the calorific value of fuel, ensure the driver's safe driving and improve the air quality in the car car. In view of the different uses of various filters, different filters on the market can only filter the corresponding media. When an emergency occurs, different types of filters cannot be replaced with each other to solve the problem, and the product versatility is poor; and manufacturers need Different production lines are used to produce...

Problems solved by technology

In view of the different uses of various filters, different filters on the market can only filter the corresponding media. When an emergency occurs, different types of filters cannot be replaced with each other to solve the problem, and the product versatility is poor; and manufacturers need Different production lines are used to produce different types of filters, and the production cost is high; the existing filter element is made of glued filter body and end cover. When the filter element fails, the entire filter element needs to be replaced, resulting in great waste. Technicians use the method of clamping the filter body on the end cover to improve this situation, but in this way, only the outer ring of the end cover is provided with a stopper, and the positioning is insufficient. When the fluid pressure is too high, the filter body is very easy to filter The empty pipe in the center of the body is displaced, deformed or even fails, and the cost of the filter element is high; when the filter body fails, the filter body and the end cover need to be taken out together, and then installed into the inner cavity of the filter after assembly, which is inconvenient to install and disassemble
