Abstract
The invention discloses an automatic alarm sensor for plugging of air filter used in car. A shell is bonded with a switch seat together. Static contacting pieces are set on two connectors in the switch seat and they are communicated with two connectors. In the shell there is a sensor mechanism constituted by a core shaft, a spring seat, a spring, a gasbag and moving contacting pieces. The spring seat, moving contacting pieces, the gasbag and the core shaft are a component, which can slide in the shaft direction of core shaft. In the shell there is an adjusting nut which can adjust the spring pressure. When the air filter is plugged, negative pressure at the intake port can be generated to absorb the gasbag to drive moving contacting pieces communicate with static contacting pieces so that two connectors are communicated and outer electrical source, indicator light or buzzer works to hint drivers that air filters can be maintained. The invention is provided with notable energy saving performance and environmental protection performance. It can be applied in multiple vehicle types.

Embodiment
Below in conjunction with accompanying drawing the embodiment of the invention is described in further detail:
The embodiment of the invention 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.
Also be provided with the adjusting nut 7 of an adjustable springs pressure in the housing 1, it places the left side of spring 5, can come the preload pressure of Regulation spring 5 to regulate alarm pressure according to the requirement of different automobile types air-strainer.
In order to adapt to domestic various vehicles, be set for the eccentric between the intake interface 14 of housing 1 and the connection jaws 15 of switch base 2, the intake interface 14 of housing 1 is a stepped shape standard universal interface, the outside of switch base 2 is provided with spiral of Archimedes 16.The Sealing of air bag 6 for making by rubber material.
Housing novelty of the present invention, attractive in appearance, its housing 1 is provided with stiffening rib 13.The present invention is actual to be a pressure overload switch, and the intake interface 14 on its left side can external engine intake, the wiring terminal interface 15 on its right can connect ABAP Adapter 11, tutorial light or buzzer 12.When air filtering gas was working properly, intake interface 14 was in normal state, and mandrel 10 assemblies are under the effect of spring force, make movable touching plate 9 and static touching plate 8 be in normally open, promptly under the normal state, two wiring terminals 3 do not communicate, at this moment, tutorial light or buzzer 12 are not worked.And when in a single day air-strainer takes place to stop up, motor is air-breathing will to form negative pressure owing to suction port stops up in the chamber that causes the present invention left side intake interface 14, this moment, negative air pressure can be drawn air bag 6, making air bag 6 overcome spring 5 pressure pushes mandrel 10 assemblies to left side and moves, when negative air pressure reaches certain value, movable touching plate 9 contacts with static touching plate 8 and communicates, two wiring terminals 3 are in the circuit on-state, at this moment, tutorial light or buzzer 12 work need be carried out maintaining to air filtering with the prompting driver.
