Abstract
The utility model discloses an automatic blocking alarm sensor of an automotive air filter, which comprises a case body and a switch seat that are stuck together. Static contacts conducting to the switch seat are respectively arranged on the two connectors in the switch seat, and a sensing structure comprising a core shaft, a spring seat, a spring, an air bag and dynamic contacts is arranged in the case body. The component structured with the spring seat, the dynamic contacts, the air bag and the core shaft can axially slide along the core shaft. A regulating nut capable of regulating the spring pressure is arranged in the case body. When the air filter is blocked, an air inlet port can generate negative pressure to suck the air bag that then drives the dynamic contacts to conduct with the static contacts, as a result the two connectors are connected, and thus the external power supply, indicating light or buzzer starts to work, prompting a driver that the air filter needs to be maintained. The utility model has the advantages of notable efficacy of energy saving and environmental protection.

Embodiment
Below in conjunction with accompanying drawing the utility model embodiment is described in further detail:
The utility model embodiment is provided with housing 1, includes switch base 2 on the housing 1, and is bonding as a whole by adhesive material between housing 1 and the switch base 2.Be provided with in the switch base 2 on two winding terminals, 3, the two winding terminals 3 and be respectively equipped with the static touching plate 8 that communicates with it.Under the normal state, two winding terminals 3 are that insulation disconnects each other, that is to say normally open.
Be provided with the sensing mechanism of forming by mandrel 10, spring seat 4, spring 5, air bag 6 and movable touching plate 9 in the housing 1.Spring seat 4 and movable touching plate 9 rivet clasps are on mandrel 10.Spring 5 is located on the spring seat 4, and the endoporus of air bag 6 tightly is placed on the spring seat 4, and the edge, outer ring of air bag 6 is pressed on the housing 1 by switch base 2.Be arranged with two holes on the movable touching plate 9, two wiring terminals 3 insert in respectively in two holes of movable touching plate 9.Be provided with certain clearance between wiring terminal 3 and the movable touching plate 9, make to keep the state of insulation that do not communicate between wiring terminal and the movable touching plate.The center of movable touching plate 9 is by mandrel 10 fixed supports.Spring seat 4, air bag 6, movable touching plate 9 and mandrel 10 are an assembly, can endwisely slip along mandrel 10.When mandrel 10 moved to left, movable touching plate 9 also moved to left immediately, and movable touching plate 9 is touched with two static touching plates 8 and made it to communicate, and this moment, two wiring terminals 3 communicated; When mandrel 10 moved to right, movable touching plate 9 separated with two static touching plates 8, and this moment, two wiring terminals 3 did not communicate.Movable touching plate 9 plays the effect of switch plate at this.
