Abstract

The utility model relates to an oil liquid filter which comprises a filter element and a shell, wherein the filter element comprises a cylindrical filter body and a cone-shaped filter body, the cone-shaped filter body is arranged in the cylindrical filter body and the bottom of the cone-shaped filter body and the end part of the cylindrical filter body are integrally fixed, the filter element is installed in the shell, the inner cavity of the shell is divided into an inner cavity and an outer cavity through the cylindrical filter body, an inner cavity inlet and an outer cavity inlet of the oil liquid are formed at one end of the shell, an inner cavity outlet is formed at the other end of the shell, the oil liquid respectively enters into the inner and outer cavities of the shell through the inner cavity inlet and the outer cavity inlet, the oil liquid entering into the outer cavity filtered by the cylindrical filter body flows out through the inner cavity outlet, and the oil liquid entering into the inner cavity filtered by the cone-shaped filter body flows out through the inner cavity outlet. The oil liquid filter provided by the utility model has the beneficial effects that by improving the existing filter element, the cone-shaped filter structure is additionally arranged in the cylindrical filter body, so that the fuel or lubricating oil filter flow and the filter effect are improved, and the normal work of the machine is guaranteed.

Description

A kind of oil filter

Technical field

The utility model relates to a kind of oil filter.

Background technology

Existing fuel oil or lubricating oil cleaner comprise filter casing and inner tubular element, tubular element filter area size is subject to filter casing size restrictions, the filtering traffic of tubular element is too small, filter core is very easily stopped up by foul and causes fluid to pass through, engine misses or lubricating system were lost efficacy, the aperture that conventionally can only increase cleaner dimensions or increase filter bores, improves cleaning maintenance frequency guarantee filter effect.

Utility model content

Technical problem to be solved in the utility model is: a kind of oil filter is provided, is not increasing filter casing size and tubular element size just can increase filter area.

The utility model solves the technical scheme that its technical problem adopts: a kind of oil filter, comprise filter core and shell, filter core comprises tubular filtering bodies and taper filtering bodies, taper filtering bodies is arranged in tubular filtering bodies, and the end of the bottom of taper filtering bodies and tubular filtering bodies is fixed as one, filter core is installed in the enclosure, shell inner cavity is divided into inner chamber and exocoel by tubular filtering bodies, one end of shell has inner chamber import and the exocoel import of fluid, the other end of shell has inner chamber outlet, fluid enters respectively inner chamber and the exocoel of shell by inner chamber import and exocoel import, the fluid that enters exocoel passes through after tubular filtering bodies is filtered to export outflow by inner chamber, the fluid that enters inner chamber exports outflow by inner chamber after filtering by taper filtering bodies.

Further limit, between the end of filter core and shell, be provided for the sealing ring of sealing.

The beneficial effects of the utility model are: by existing filter core is improved, increase taper filtration in tubular filtering bodies, improved fuel oil or lubrication oil filtration flow and filter effect, guarantee machine is normally worked.

Accompanying drawing explanation

Below in conjunction with drawings and Examples, the utility model is further illustrated;

Fig. 1 is structural representation of the present utility model;

Wherein, 1. shell, 1-1. exocoel, 1-2. inner chamber, the import of 1-3. exocoel, the import of 1-4. inner chamber, the outlet of 1-5. inner chamber, 2-1. tubular filtering bodies, 2-2. taper filtering bodies, 3. sealing ring.

The specific embodiment

As shown in Figure 1, a kind of oil filter, comprise filter core and shell 1, filter core comprises tubular filtering bodies 2-1 and taper filtering bodies 2-2, taper filtering bodies 2-2 is arranged in tubular filtering bodies 2-1, and the end of the bottom of taper filtering bodies 2-2 and tubular filtering bodies 2-1 is fixed as one, filter core is arranged in shell 1, shell 1 inner chamber is divided into inner chamber 1-2 and exocoel 1-1 by tubular filtering bodies 2-1, one end of shell 1 has inner chamber import 1-4 and the exocoel import 1-3 of fluid, the other end of shell 1 has inner chamber outlet 1-5, fluid enters respectively inner chamber 1-2 and the exocoel 1-1 of shell 1 by inner chamber import 1-4 and exocoel import 1-3, the fluid that enters exocoel 1-1 exports 1-5 by inner chamber after filtering by tubular filtering bodies 2-1 and flows out, the fluid that enters inner chamber 1-2 exports 1-5 by inner chamber after filtering by taper filtering bodies 2-2 and flows out.

Between the end of filter core and shell 1, be provided for the sealing ring 3 of sealing.
