Abstract
The utility model relates to a filter seat of a filter, and the structure is as follows: an oil inlet cavity and an oil outlet cavity are arranged in a body, a differential pressure sensor which is respectively and independently communicated with the oil inlet cavity and the oil outlet cavity is further arranged on the body, and the differential pressure sensor is connected with an input end of an automobile alarm circuit through a conducting wire. The differential pressure sensor is any one of a strain type differential pressure sensor, a pressure spring type differential pressure sensor and a semiconductor type differential pressure sensor. After the filter seat is arranged on a filter tank of the filter, the filter can be used. When an engine is in use, the blockage status of a filter element can be accurately judged by detecting the change of pressure difference between the oil inlet cavity and the oil outlet cavity in the filter seat; when the filter element is blocked at a certain degree (that is the pressure difference achieves the stipulated value), the automobile alarm circuit can alarm immediately for reminding a user of replacing the filter in time, in other words, the filter does not need to be replaced according to working time of the engine or driving mileage of an automobile, as long as the alarm is emitted, the user can know that the service life of the filter is ended, therefore, the damages to the engine caused by the blockage of the filter element can be prevented, and the harm to the engine caused by the fake and forged filter is prevented, so that the replacement of the filter at appropriate time can be realized.
Description
Technical field
The utility model relates to filter parts, particularly relates 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.
The model utility content
Technical problem to be solved in the utility model 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 utility model 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 the utility model filter base 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
