This warning element comprises image warning device or sound warning device.
This sensing element also comprises the helical spring being fixed in this housing, and this first contact is between this elastic membrane and helical spring.
Above-mentioned engine fuel system early warning failure device, occurs when abnormal, just can remind autoist to note in vehicle fuel supply, be therefore conducive to can minimizing accident generation.
Brief description of the drawings
Fig. 1 is the schematic diagram of the utility model embodiment's engine fuel system early warning failure device.
Fig. 2 is the schematic diagram of the engine fuel system early warning failure device shown in Fig. 1 in the time reporting to the police.
Embodiment
Below in conjunction with drawings and Examples, engine fuel system early warning failure device of the present utility model is described in further detail.
Refer to Fig. 1, the utility model embodiment's engine fuel system early warning failure device 100 can be used for being connected with the oil feed line 200 of automobile.Engine fuel system early warning failure device 100 comprises housing 10, sensing element 30 and warning element 50.Housing 30 has the opening 12 being communicated with oil feed line 200.Sensing element 30 comprises interconnective elastic membrane 32 and contact-making switch 34.Elastic membrane 32 is positioned at this housing 30 with contact-making switch 34.Contact-making switch 34 has the first contact (figure is mark not) and second contact (figure not mark) corresponding with the first contact.The first contact of contact-making switch 34 is connected with elastic membrane 32.Warning element 50 is electrically connected with contact-making switch 34.
Specifically in the present embodiment, elastic membrane 32 is located at opening 12 places of housing 10, and the inside of housing 10 is divided into the first receiving cavity (figure is mark not) and the second receiving cavity (figure is mark not).The first receiving cavity is near oil feed line 200, and fuel oil 201 can flow in the first receiving cavity by opening 12, and oppresses elastic membrane 32 and allow elastic membrane 32 deform.The first contact of contact-making switch 34 is positioned at the second receiving cavity, can not contact with fuel oil 201.
The first contact of contact-making switch 34 can be connected with elastic membrane 32 by rigid rod 36, in the time that being out of shape, elastic membrane 32 can drive the first contact follow motion of contact-making switch 34, for example, in the time of oil 201 regular supply in oil feed line 200, the first contact of contact-making switch 34 is separated; In the time that the oil 201 in oil feed line 200 is missed, because the pressure of giving elastic membrane 32 reduces, elastic membrane 32 can resile, thereby drives the first contact of contact-making switch 34 to the direction motion of the second contact, and can contact with the second contact, the circuit loop of warning element 50 is communicated with.
Warning element 50 can comprise image warning device or sound warning device, for example warning light or buzzer.For strengthening alarm function, warning element 50 can be located in the cockpit of automobile, for example, near automobile instrument panel.In the time that warning element 50 is reported to the police, can allow timely driver know, and then adopt an effective measure, avoid the generation of accident.
In 100 using processs of above-mentioned engine fuel system early warning failure device, when the fuel oil 201 in oil feed line 200 is during in normal pressure state, fuel oil 201 can press down elastic membrane 32, the first contact and second contact of the contact-making switch 34 being connected with elastic membrane 32 are separated, contact-making switch 34 is in opening state, and warning element 50 is not worked (as shown in Figure 1).In the time that the oil 201 in oil feed line 200 occurs to reveal, the pressure decreased of oil feed line 200 interior fuel oils will be caused, elastic membrane 32 will move up under self elastic reaction, and then drive the first contact of contact-making switch 34 to contact with the second contact, make contact-making switch 34 in closed state, whole circuit is connected, and warning element 50 sends warning (as shown in Figure 2).Adopt above-mentioned engine fuel system early warning failure device 100, occur when abnormal, for example, when oil pressure reduces, just can remind autoist to note in vehicle fuel 201 supply, be therefore conducive to can minimizing accident generation.
Further, for strengthening the ability of return motion of the first contact of contact-making switch 34, above-mentioned sensing element 30 also can comprise helical spring 38.Helical spring 38 is fixed in housing 10, and the first contact of contact-making switch 34 can, between elastic membrane 32 and helical spring 38, provide the ability of return motion simultaneously for the first contact with elastic membrane 32 and helical spring 38.
The above, it is only preferred embodiment of the present utility model, not the utility model is done to any pro forma restriction, although the utility model discloses as above with preferred embodiment, but not in order to limit the utility model, any those skilled in the art, do not departing within the scope of technical solutions of the utility model, when can utilizing the technology contents of above-mentioned announcement to make a little change or being modified to the equivalent embodiment of equivalent variations, in every case be not depart from technical solutions of the utility model content, any simple modification of above embodiment being done according to technical spirit of the present utility model, equivalent variations and modification, all still belong in the scope of technical solutions of the utility model.
