Description
Technical field
The present invention relates to cleaner technical field, specifically a kind of diesel fuel filter water level false alarm prevention detection and draining dress
Put.
Background technology
Diesel fuel filter level sensor is to detect the water level in diesel fuel filter.When the height that catchments of cleaner is reached
During the detection electrode of level sensor, sensor starts to report to the police, and automobile ECU provides an instruction and notifies driver to bleed off cleaner
Interior water.
Find during actually used, as automobile occurs pitch under steam unavoidably, in filter water accumulation cup
Water and oil also and then rock, so as to the situation for false alarm occur sometimes.On the other hand, in draining, driver turns on ponding
The plug of cup bottom is discharged water, and plug and water accumulating cup are Screw assembly structures, and when driver's hand reaches bottom of car, operation is not
And the easy stripped thread of screw thread is damaged just,.
Content of the invention
It is an object of the invention to provide a kind of diesel fuel filter water level false alarm prevention detection and drainage arrangement, one side of the device
Face can prevent from reporting by mistake in sensed water level, on the other hand make driver easy to operate in draining.
The technical solution adopted for the present invention to solve the technical problems is：
A kind of diesel fuel filter water level false alarm prevention detection and drainage arrangement, level sensor is in water accumulating cup；The water accumulating cup
Bottom is provided with circuit board and the piezoelectric film sensor for detecting hydraulic pressure in water accumulating cup, be integrated with circuit board comparator,
With door and energization delay relay, the in-phase input end connection piezoelectric film sensor of comparator, inverting input linker
Quasi- voltage, output end connection and the input of door, be connecteds level sensor with another input of door, with the output end of door and
Energization delay relay is connected, and energization delay relay output end leads to diesel vehicle ECU by cable；The water accumulating cup bottom
Plug position settings button formula draining valve.
The invention has the beneficial effects as follows, due to oily different with the proportion of water, during cleaner water-oil separating, ponding
Water level in cup is gradually increasing, thus the base pressure in water accumulating cup also accordingly can rise, and the change of pressure can react water outlet
The change of position；When water level rises to the height for needing to report to the police, piezoelectric film sensor sends high level with level sensor,
High level is exported to energization delay relay with door, energization delay relay sends a signal to diesel vehicle ECU through time delay, from
And avoid the wrong report phenomenon caused only with level sensor；In addition, substituting plug, draining using push button draining valve
When, as long as pressing the button, easy to operate, be hardly damaged.
Description of the drawings
The present invention is further described with reference to the accompanying drawings and examples：
Fig. 1 is the structural representation of the present invention；
Fig. 2 is the electrical schematics of the present invention.
Specific embodiment
In conjunction with shown in Fig. 1 and Fig. 2, the present invention provides a kind of diesel fuel filter water level false alarm prevention detection and drainage arrangement, water
In the water accumulating cup 1, the interior bottom of water accumulating cup 1 is provided with for detecting the piezoelectric film sensor of hydraulic pressure in water accumulating cup level sensor 2
3, the outer bottom of water accumulating cup 1 is provided with circuit board 4, is integrated with comparator N1 and door and energization delay relay KT on circuit board 4,
In-phase input end connection piezoelectric film sensor 3, the inverting input connection reference voltage V of comparator N1CC, output end connection with
The input of door, is connected level sensor 2 with another input of door, output end and the energization delay relay KT phases with door
Even, energization delay relay KT output ends lead to diesel vehicle ECU by cable 5；The plug position settings button of 1 bottom of water accumulating cup
Formula draining valve 6；The power supply of circuit board 4 and each sensor is provided by cable 5 by diesel vehicle ECU.
Traditional cleaner water level detecting only has level sensor, and the present invention is different with the proportion of water according to oil, introduces pressure
Conductive film sensor 3, during cleaner water-oil separating, the water level in water accumulating cup 1 is gradually increasing, thus in water accumulating cup
Base pressure also accordingly can rise, and the change of pressure can reflect the change of water level；When water level rises to the height for needing to report to the police
When spending, 3 output voltage of piezoelectric film sensor is more than reference voltage VCC, comparator N1 output high level can be according to different
Vehicle and service condition are adjusting VCCSize, now level sensor 2 also send high level, export high level to logical with door
Electric time-delay relay KT, energization delay relay KT send a signal to diesel vehicle ECU through time delay；Two biographies of different nature
Sensor carries out detection judgement to water level simultaneously, so as to avoid the wrong report phenomenon caused only with level sensor；In addition,
Plug is substituted using push button draining valve 6, during draining, as long as pressing the button, easy to operate, be hardly damaged.
The above, is only presently preferred embodiments of the present invention, not makees any pro forma restriction to the present invention；Appoint
What those of ordinary skill in the art, under without departing from technical solution of the present invention ambit, using the side of the disclosure above
Method and technology contents make many possible variations and modification, or the equivalent reality for being revised as equivalent variations to technical solution of the present invention
Apply example.Therefore, every content without departing from technical solution of the present invention, is done to above example according to the technical spirit of the present invention
Any simple modification, equivalent, equivalence changes and modification, still fall within the range of technical solution of the present invention protection.
