Abstract

The utility model discloses an oil filter, comprising a filter case and a filter element (7) arranged within the filter case, and is characterized in that a magnetizing filter screen (9) is arranged in the filter case; the filter case consists of an upper cup (1) and a bottom cup (8) which are connected by threaded; the top cap (1) is provided with an oil inlet and an oil outlet (2 , 4); the magnetizing filter screen (9) and the filter element (7) are arranged within the bottom cup (8); the guide bar (6) of the filter element is arranged in the bottom cup (8) by a supporting spring (10); the filter element (7) is arranged on the guide bar (6). The oil filter of the utility model is capable of not only filtering a metal particle in a lubricating oil but also adsorbing a micron order metal particle in the lubricating oil, thereby guaranteeing the cleanness of the lubricating oil effectively; meanwhile the oil filter of the utility model has the advantages of good detachability, easy change and simple and convenient maintenance, thereby effectively utilizing resources and saving use-costs.

Description

A kind of oil filter

Technical field

The present invention relates to a kind of oil filter, a kind of dismountable, oil filter of more specifically saying so with magnetic adsorptivity.

Background technique

In motor, the particulate of the constantly launched machine wearing and tearing of machine oil and the extraneous contaminating impurity that falls into, the acidic materials that dissolve in machine oil and the insoluble gelatinous precipitate that produced by thermal oxidation.Solid particles in these impurity can increase the wearing and tearing of motor, and colloid can make gluing takes place between piston and the parts such as piston ring, valve and valve guide bushing.The effect of oil filter will guarantee the cleaning of lubricant oil with the above-mentioned objectionable impurities filtering that is present in the machine oil exactly, thereby the component of protection motor prolong its working life.So the effect of oil filter in lubrication system is very big.

The oil filter of motor is the papery filter core basically at present, this filter core can filter particulates a large amount of in the machine oil, but for metal particles a lot of in the machine oil, as fricative particulate between cylinder sleeve of engine and the piston, diameter is very little, generally all be in micron order, filter paper is very little to the effect of these micro particle filterings.On the other hand, oil filter is an attrition component, general oil filter will be changed once for 5000～10000 kilometers in vehicle operating, present oil filter all is to be designed to monolithic construction, in case filter core stops up, whole filter cleaner all must be scrapped processing, not only resource is caused great waste, and user cost increases.

Summary of the invention

The purpose of this utility model is: a kind of oil filter is provided, the effective metal particle in the filtering lubricant oil, can also disassembly-type renew cartridge more, easy and simple to handle, change easily, economize on resources, reduce maintenance cost.

Technical solution of the present utility model is: this filter cleaner comprises filter case, and filter core is installed in filter case, it is characterized in that: at the peripheral magnetization filter screen of installing of filter case inner filter core.

In a kind of oil filter of the present utility model, filter case is made up of by being threaded top lid and bottom cup, establishes on the top cover into and out of oilhole, and magnetization filter screen and filter core are installed in end cup.

In a kind of oil filter of the present utility model, in end cup, the filter core guide rod is installed, on the filter core guide rod filter core is installed by supported spring.

In a kind of oil filter of the present utility model, design has the groove of being convenient to dismantle filter cleaner on cup at the bottom of the filter cleaner.

In a kind of oil filter of the present utility model, the filter cleaner top cover is installed on the engine cylinder-body by mounting plate.

During use, lubricant oil from motor, enter the oil filter from filler opening, when metal particle in the lubricant oil runs into the magnetization filter screen, metal granule just is attracted on the magnetization filter screen, and the machine oil that is filtered metal particle further filters by filter core, passes through the filter core guide rod then, at last, filter the lubricant oil that cleans the back enters motor through oil outlet main oil gallery.

When the life-span of filter core reaches the rating life, only need turn on the connecting thread of top lid and bottom cup, taking off end cup is replaceable new filter core, and filter core is in the outside of filter core guide rod, and the filter core guide rod can play the positioning action to filter core.

The utlity model has following advantage:

1, oil filter body is designed to up and down two-part of top lid and bottom cup, two-part are directly by being threaded, and convenient disassembly is changed easyly, and maintenance is easy, and resource has been carried out effective utilization, has saved user cost.

2, on cup at the bottom of the oil filter, pass through the filter core guide rod filter core has been installed, guaranteed the position degree of filter core.

3, the filter core outer surface has one deck magnetization filter screen, filtering the metal particle in the lubricant oil, can adsorpting lubrication oil in micron-sized metal particle, guaranteed the cleaning of lubricant oil effectively.

4, design has the groove of being convenient to dismantle filter cleaner on cup at the bottom of the filter cleaner.

Fig. 1 is an oil filter header field schematic representation.

Fig. 2 is a cup part schematic representation at the bottom of the oil filter.

Among the figure: 1 top cover, 2 oil inlet holes, 3 mounting plates, 4 oil outlets, 5 grooves, 6 filter core guide rods, 7 filter cores, 8 end cups, 9 magnetization filter screens, 10 supported springs.

Embodiment

1,2 the utility model is described in further detail in conjunction with the accompanying drawings.

This filter cleaner comprises filter case, and filter core 7 is installed in filter case, it is characterized in that: at the filter case inner filter core 7 peripheral magnetization filter screens 9 of installing.

In a kind of oil filter of the present utility model, filter case is made up of by being threaded top cover 1 and end cup 8, establishes on the top cover 1 into and out of oilhole 2,4, and magnetization filter screen 9 and filter core 7 are installed in end cup 8.

In a kind of oil filter of the present utility model, in end cup 8, filter core guide rod 6 is installed, filter core 7 is installed on the filter core guide rod 6 by supported spring 10.

In a kind of oil filter of the present utility model, filter cleaner top cover 1 is installed on the engine cylinder-body by mounting plate 3, the shape that the mounting plate 3 of oil filter can match according to the junction plane design with engine cylinder-body.

In a kind of oil filter of the present utility model, design has a groove 5 of being convenient to dismantle filter cleaner on cup at the bottom of the filter cleaner, more convenient disassembly during renew cartridge.
