Abstract

The invention relates to a filter seat. The structure of the filter seat is that an oil inlet cavity and an oil outlet cavity are arranged in a body; the body is provided with differential pressure transducers which are respectively independently communicated with the oil inlet cavity and the oil outlet cavity; and the differential pressure transducers are connected with the input end of an automobile alarm circuit through wires. The differential pressure transducer is a strain type differential pressure transducer, pressure spring type differential pressure transducer or semiconductor type differential pressure transducer. The filter can be used immediately after the filter seat is installed on the filter tank. When an engine works, the change of the differential pressure between the oil inlet cavity and the oil outlet cavity in the filter seat is detected to accurately judge the blocking status of the filter element; and when the filter element is blocked to a certain degree (the differential pressure reaches the specified value), the automobile alarm circuit can immediately give an alarm to remind a user of replacing the filter in time. In other words, it is not necessary to replace the filter according to the working time of the engine or the running mileage of an automobile. As long as the automobile alarm circuit gives an alarm, it indicates that the service life of the filter is over, thereby avoiding the engine damage due to filter element blocking and preventing the engine from being damaged by a poor-quality filter, so that the user can replace the filter in time.

Description

Filter base

Technical field

The present invention relates to filter parts, particularly relate to a kind of filter base.

Background technique

Filter cleaner is divided into air-strainer, fuel filter and oil filter, on the filter tank of every kind of filter cleaner filter block to be installed, be provided with in the body of filter block and oil suction chamber that the filter tank inner chamber communicates separately respectively with go out oil pocket, filter core is set in the filter tank, bypass valve also is installed in the filter tank of oil filter.

In the engine operation, when the filter core in air-strainer and the fuel filter blocks, motor or be short of power, or quit work; When the filter core in the oil filter blocked, unfiltered machine oil directly entered motor by the bypass valve in the oil filter without filter core, and this has a strong impact on the life-span of motor.

Filter core will in time be changed filter cleaner after blocking, and generally by manufacturer rule of thumb, change at once behind regulation engine operation certain hour or the certain milimeter number of automobile running, but also there is bigger potential safety hazard in this, promptly; Under the big situation of motor running-in period or air, oil material contamination degree, often do not work stipulated time or automobile of motor do not drive to before the regulation milimeter number, just makes that the filter core in the filter cleaner blocks (at this moment, the user is ignorant toward contact).

In addition, filter core does not also block sometimes, and filter cleaner is just changed in advance, causes bigger waste.

In sum, when numerous users have no way of knowing exactly at all and in other words, to be difficult to accomplish change filter cleaner by this replacing filter cleaner in good time.

Summary of the invention

Technical problem to be solved by this invention provides a kind of filter base that is fitted on the filter cleaner filter tank, in the engine operation, by detecting oil suction chamber and the variation that goes out the pressure difference of oil pocket in this filter block, just can accurately judge the clogged conditions of filter core, remind the user in time to change filter cleaner.

For solving the problems of the technologies described above, the invention provides a kind of filter base, its structure is: oil suction chamber is set in the body and goes out oil pocket, also setting and oil suction chamber and go out the differential pressure pickup that oil pocket communicates separately respectively on the body, differential pressure pickup is connected by the input end of lead with the auto alarm circuit.

For the purpose of the concise explanation problem, below filter base of the present invention is all abbreviated as this filter block.

After this filter block was fitted on the filter cleaner filter tank, filter cleaner can use.

After adopting above technological scheme, in the engine operation, by detecting oil suction chamber and the variation that goes out the pressure difference of oil pocket in this filter block, accurately judge the clogged conditions of filter core, when filter core is clogged to a certain degree (when described pressure difference reaches the numerical value of regulation), will allow the auto alarm circuit alarm immediately, remind the user in time to change filter cleaner, in other words, need not to change filter cleaner,, know that just end the working life of filter cleaner as long as report to the police according to the operating time of motor or the milimeter number that travels of automobile, like this, can prevent because of of the infringement of filter core obstruction motor; Also can prevent of the harm of fake and forged filter cleaner, thereby accomplish to change filter cleaner in good time motor.

In addition, can make that also the utilization efficiency of filter cleaner and reliability significantly improve,, bring convenience for simultaneously the maintenance of motor, avoid the waste of unnecessary too early replacing filter cleaner significance is arranged the working life of improving motor.

Described differential pressure pickup is any in strain type differential pressure pickup, pressure spring type differential pressure pickup, the semiconductor-type differential pressure pickup.

This filter block can be adaptive with state IV, state's V filter cleaner, by the variation that detects oil suction chamber in this filter block and go out the pressure difference of oil pocket, judges the clogged conditions of filter core in view of the above, is a kind of intelligentized filter block.

Description of drawings

Fig. 1 is the structural representation of the present invention when using;

Fig. 2 is that the A of Fig. 1 is to view.

Embodiment

Below in conjunction with accompanying drawing, the present invention is specifically described by mode of execution:

Embodiment 1

Referring to Fig. 1, Fig. 2, the filter tank 2 of filter cleaner is installed filter core 21 by 22 equipped these filter blocks of the center tube on it in the filter tank 2.Be provided with in the body 1 of this filter block and oil suction chamber 11 that the inner chamber of filter tank 2 communicates separately respectively with go out oil pocket 12, jack 15 by vertical layout on the body 1 is provided with differential pressure pickup 3, oilhole 13 and oilhole 14 also are set in the body 1, oilhole 13 communicates with the bottom of oil suction chamber 11 and jack 15 respectively, oilhole 14 communicates with the middle part that goes out oil pocket 12 and jack 15 respectively, like this, make differential pressure pickup 3 and oil suction chamber 11 and go out oil pocket 12 and communicate separately respectively, differential pressure pickup 3 is connected (not shown described lead and auto alarm circuit in the accompanying drawing) by lead with the input end of auto alarm circuit.Differential pressure pickup 3 is the strain type differential pressure pickup.
