Description

Automobile filter

Technical Field

The utility model relates to an automobile filter equipment field specifically is an automobile filter.

Background

The existing oil filter generally filters impurities through a filter element, when filter paper is used for a period of time, the filter paper is gradually blocked by impurities in engine oil to lose oil filtering and oil supply functions, in order to ensure smooth oil supply, most of the oil filters are provided with a bypass valve structure, and when the filter element is blocked, the bypass valve is opened under the action of oil pressure to directly supply unfiltered engine oil so as to ensure that an engine can maintain normal operation in emergency.

The oil filter mainly comprises a dirty oil inlet, a shell, a central pipe, filter paper and a bypass valve, namely after the engine is cold started or a filter element is blocked, dirty oil can flow through the central pipe from an overflow valve and the unfiltered oil is directly supplied to ensure that the engine can maintain normal operation in emergency, namely, the problem that the filtered engine oil enters a side oil valve to cause certain damage to the engine at present exists.

SUMMERY OF THE UTILITY MODEL

The utility model discloses a main objective provides an automobile filter, problem in can effectual solution background art.

In order to achieve the above purpose, the utility model adopts the following technical scheme:

the utility model provides an automobile filter, which comprises an outer shell, the sump oil import, the center tube, the filter core, the surface at the center tube is established to the filter core cover, the position that shell internal surface bottom is located between shell and the filter core is provided with the check valve, the shell bottom still is provided with and blocks up filter equipment, it includes the bottom casing to block up filter equipment, the position fixedly connected with communicating pipe that bottom casing internal surface is located the center tube, communicating pipe internal surface and center tube intercommunication, a plurality of logical oilholes have been seted up to the communicating pipe surface, the filter core is also inlayed and established to the communicating pipe internal surface, after the cover is established the filter core jam at the center tube surface, can open the check valve in the liftout, sump oil flows into in.

Further, shell bottom internal surface and bottom casing threaded connection, communicating pipe top and center tube threaded connection block up filter equipment and can dismantle, can improve the utilization ratio of whole device through the renew cartridge.

Furthermore, the position that the outer surface of the communicating pipe is located the oil through hole is wrapped by a metal filter screen, so that part of impurities in the dirty oil can be blocked outside the communicating pipe, and the service life of the filter element inside the communicating pipe can be prolonged.

Furthermore, the position that the center tube internal surface is close to communicating pipe fixedly connected with check valve avoids in the normal operating time through filterable oil flow in the shell to influence its inside filter core life in communicating pipe.

The working principle and the beneficial effects are as follows: the position that is located between shell and the filter core through shell internal surface bottom is provided with the check valve, and the shell bottom still is provided with and blocks up filter equipment, blocks up filter equipment and includes the bottom casing, and bottom casing internal surface is located the position fixedly connected with communicating pipe of center tube, and communicating pipe internal surface and center tube intercommunication, a plurality of logical oilholes have been seted up to the surface of communicating pipe, and the filter core is also inlayed to the internal surface of communicating pipe, problem that can effectual solution background art exists.

(1) After the filter core that establishes through the cover at the center tube surface blocks up, can push up open the check valve, and the sump oil flows into in the bottom casing, filters through the filter core in the intercommunication pipe after through the center tube flow direction engine, problem that can effectual solution background art exists can the effectual problem that solves the background art and exist.

(2) Through shell bottom internal surface and bottom casing threaded connection, communicating pipe top and center tube threaded connection block up filter equipment and can dismantle, can improve the utilization ratio of whole device through the renew cartridge.

Drawings

Fig. 1 is a schematic sectional view of the housing of the present invention.

In the figure: 1. a housing; 2. a dirty oil inlet; 3. a central tube; 4. a filter element; 5. a bottom housing; 6. a one-way valve; 7. a communicating pipe; 8. an oil through hole; 9. a metal screen; 10. a check valve.

Detailed Description

The invention will be better understood from the following examples.

The drawings in the specification show the structure, ratio, size, etc. only for the purpose of matching with the content disclosed in the specification, so as to be known and read by those skilled in the art, and not for the purpose of limiting the present invention, so the present invention does not have the essential meaning in the art, and any structure modification, ratio relationship change or size adjustment should still fall within the scope covered by the technical content disclosed in the present invention without affecting the function and achievable purpose of the present invention. Meanwhile, the terms "upper", "lower", "front", "rear", "middle", and the like used in the present specification are for the sake of clarity only, and are not intended to limit the scope of the present invention, and changes or adjustments of the relative relationship thereof are also considered to be the scope of the present invention without substantial changes in the technical content.

As shown in figure 1, the automobile filter comprises a shell 1, a sump oil inlet 2, a central tube 3 and a filter element 4, wherein the filter element 4 is sleeved on the outer surface of the central tube 3, a one-way valve 6 is arranged at the position, between the shell 1 and the filter element 4, at the bottom of the inner surface of the shell 1, a blocking filter device is also arranged at the bottom end of the shell 1, the blocking filter device comprises a bottom shell 5, a communicating tube 7 is fixedly connected at the position, at which the inner surface of the bottom shell 5 is positioned, of the central tube 3, the inner surface of the communicating tube 7 is communicated with the central tube 3, a plurality of oil through holes 8, when the filter element sleeved on the outer surface of the central tube is blocked, the one-way valve is jacked open, the dirty oil flows into the bottom shell, the filter element in the communicating pipe filters the air and then flows to the engine through the central pipe, so that the problems in the background art can be effectively solved.
