Accompanying drawing explanation
Fig. 1 is the schematic diagram of the automobile oil filter failure alarm device of this utility model embodiment.
Fig. 2 is the schematic diagram when reporting to the police of the automobile oil filter failure alarm device shown in Fig. 1.
Detailed description of the invention
Below in conjunction with drawings and Examples, automobile oil filter failure alarm device of the present utility model is made into one
The detailed description of step.
Referring to Fig. 1, the automobile oil filter failure alarm device of this utility model embodiment is used for and oil filtration
Device 200 is connected.Oil filter 200 includes housing 22 and filter element 24.The oil-in 222, the oil circuit that are communicated with in housing 22 lead to
Road 224 and oil-out 226.Filter element 24 is located on asphalt channel 224.Filter element 24 has through hole 242, through hole 242 and oil-out 226
Connection.Automobile oil filter failure alarm device includes that power supply 12, pressure-sensing control module 14 and warning module 16.Power supply
12, pressure-sensing controls module 14 and warning module 16 is connected.Pressure-sensing controls the oil circuit of module 14 and oil filter 200
Passage 224 is connected, for sensing the change of machine oil 300 pressure in asphalt channel 224.Pressure-sensing controls module 14 for basis
In the asphalt channel 224 sensed, the change of machine oil 300 pressure is to control warning module 16, such as, control module when pressure-sensing
When in the asphalt channel 224 that 14 sense, machine oil 300 pressure exceedes predetermined value, pressure-sensing controls module 14 and just controls warning mould
Group 16 unlatching sends alarm signal.
The most in the present embodiment, pressure-sensing control module 14 can include that sensing unit 141 senses with relay 146.
Unit 141 includes fixed contact 142 and relief valve 144.Through hole 242 one end of filter element 24 connects with oil-out 226, and relative is another
One end arranges relief valve 144 on (i.e. one end bottom filter element).Fixed contact 142 is near bottom 244.On relief valve 144
It is provided with the current collector 1442 corresponding with fixed contact 142.In relief valve 144 is arranged on through hole 242 and near bottom 244.
In the case of oil filter 200 uses normally, relief valve 144 is by the bottom lock of through hole 242, so that machine oil 300
Will not filter without filter element 24 and bottom through hole 242, flow into through hole 242 and flow out from oil-out 226.Particularly, in this reality
Executing in example, relief valve 144 includes blocking cover 1444 and spring 1446.One end of spring 1446 and the housing of oil filter 200
22 fix, and the relative other end fixes with blocking cover 1444, and current collector 1442 is positioned in blocking cover 1444.At oil strainer
Clear device 200 use normal in the case of, current collector 1442 is connected to fixed contact 142 to contact.
Relay 146 includes contact point unit 1462 and the solenoid 1466 corresponding with contact point unit 1462.Contact is single
Unit 1462 includes armature contact 1463, normally opened contact 1464 and normally-closed contact 1465.Power supply 12, solenoid 1466 and sensing are single
Unit 14 connects and composes circuit loop；Power supply 12, normally-closed contact 1465, armature contact 1463 and warning module 16 connect and compose circuit
Loop.
Warning module 16 can include audible alarm or image siren.
Above-mentioned automobile oil filter failure alarm device in use, when oil filter 200 is in normal work
When making state, machine oil 300 can filter through filtration core 24 and enter through hole 242, then flows out from oil-out 226, now relief valve 144
On the pressure that born less, relief valve 144 encloses the current collector 1442 on the bottom of through hole 242, and relief valve 144
Being connected with fixed contact 142 and contact, thus power supply 12, solenoid 1466 and sensing unit 14 connect and compose at circuit loop
In connected state, the circuit loop residing for warning module 16 is in off state, and therefore warning module 16 does not works, such as Fig. 1 institute
Show.When oil filter 200 lost efficacy, such as filter element 24 filtering holes is blocked, and a large amount of machine oil 300 cannot be entered by filter element sidewall
Entering through hole 242, the pressure now born on relief valve 144 increases, when the pressure that relief valve 144 bears exceedes preset value,
Relief valve 144 is opened, and now the current collector 1442 on relief valve 144 can be followed mobile and is separated with fixed contact 142,
Thus power supply 12, solenoid 1466 and sensing unit 14 connect and compose circuit loop disconnection, and solenoid 1466 loses magnetism,
Armature contact 1463 is contacted with normally-closed contact 1465 connection, thus power supply 12, normally-closed contact 1465, armature contact 1463
And the circuit loop connection that warning module 16 connects and composes, warning module 16 works and sends alarm, reminds driver's note
Meaning, as shown in Figure 2.
Above-mentioned automobile oil filter failure alarm device, can send alarm in time when oil filter 200 lost efficacy,
Remind driver to note, and then prevent auto parts from being damaged further.
The above, be only preferred embodiment of the present utility model, not this utility model is made any in form
Restriction, although this utility model is disclosed above with preferred embodiment, but is not limited to this utility model, any ripe
Know professional and technical personnel, in the range of without departing from technical solutions of the utility model, when in the technology of available the disclosure above
Hold and make a little change or be modified to the Equivalent embodiments of equivalent variations, as long as being without departing from technical solutions of the utility model
Hold, any simple modification, equivalent variations and modification above example made according to technical spirit of the present utility model, the most still
