Background technique
Automobile, engineering machinery engine air cleaner blocking warner are using passive alarm at present, mostly by silicon
Rubber diaphragm, spring, contact, connecting rod and shell composition, technology is early, and oneself falls behind.In use due to spring aging, contact oxidation
The factors such as poor contact, vibration are corroded, make its poor accuracy of alarming, reliability and durability are undesirable.Due to operating environment
Problem makes it intake, is just completely ineffective into dirt.In addition silicon rubber diaphragm at work, is twitched, very repeatedly in alarm point
The a large amount of aqueous vapors of inspiration are easy, so that it is moist at spring, contact, water dirt corrosion is just formed, poor contact of contacts is caused, alarm is lost
Effect.
When the strainer of air cleaner blocks, negative pressure, when negative pressure reaches certain value, pressing diaphragm are generated in air inlet pipe
Contracting spring drives contact pad contact using connecting rod, and alarm is played the role of in circuit connection.And during this on the outside of diaphragm
(diaphragm is inside by air inlet pipe side) must be connect with atmosphere.Due in atmosphere moisture and dust (muddy water) be easy to be inhaled into
Inside alarm, circuit contact is corroded, causes poor contact reaction insensitive.
The inlet channel of existing air cleaner blocking warner uniquely relies on small more seldom added with water proof and dust proof measure
The fit-up gap air inlet in hole, part, it is easy to it is blocked by dust muddy water, makes its air inlet is obstructed to cause alarm work failure,
Alarm function is not had.
Summary of the invention
In order to solve problem above, the utility model provides a kind of air cleaner blocking warner, the dress of the program
It is accurate to set precision, reliable performance, long service life.And the anti-muddy water of water proof and dust proof.
The technical solution of the utility model is as follows: a kind of air cleaner blocking warner, including shell, in the shell
It is provided with A chamber and B chamber, the A chamber is connected to the atmospheric side of air cleaner blocking warner shell, and B chamber passes through air-filtering
Device is connected to engine, and ventilated membrane, microswitch, mandril, silicone rubber membrane and spring, the A chamber and B are provided in the shell
Chamber is located at the two sides of silicone rubber membrane, and the silicone rubber membrane is connect close to the side of A chamber with the mandril, the silicone rubber membrane
Spring is installed close to the side of B chamber, the mandril is provided with microswitch, the microswitch and report close to one end of A chamber
Warning lamp electrical connection, ventilated membrane are located at the air inlet of A chamber；In normal conditions, the contact of the microswitch and ejector pin contact, when
When air cleaner failure, the contact of the microswitch is separated with mandril, and microswitch is opened, and warning circuit is connected.
Technical solutions of the utility model further include: the ventilated membrane is waterproof ventilated membrane, preferably IP67 grades of waterproof and breathable
Film.
Technical solutions of the utility model further include: the air inlet side of the A chamber uses labyrinth type inlet channel.

Technical solutions of the utility model further include: closed working space is provided in the microswitch.
Technical solutions of the utility model further include: the spring is equipped with close to the side of engine and adjusts land.
Technical solutions of the utility model further include: the adjusting land is equipped with strainer close to the side of engine.
Technical solutions of the utility model further include: the strainer is made of powder metallurgy.
The utility model has the following beneficial effects: the utility model provides a kind of air cleaner blocking warner, use
High and reliable microswitch is standardized as appliance switch element, instead of stamping parts used in the past, manual assembly
Appliance switch element.Microswitch has a closed operating room, waterproof dust-proof.This just makes the reliability of alarm, service life
There is great promotion.The on-off times of microswitch are at 25 ten thousand to 1,000 ten thousand times or so, and " automobile is empty by QC/T29032-2013
Air cleaner blocking warner sensor " as defined in on-off times it is only short in 10,000 times or so service lifes.
This programme increases waterproof ventilated membrane in air cleaner blocking warner simultaneously, has both prevented the water in air
Divide to enter and has ensured internal and atmosphere connection inside alarm again.Air filter blocking warner can be made normally to detect in air inlet pipe
Pressure.
The technical solution blocks air filter using after the rubber sheath new technology of microswitch and waterproof ventilated membrane and waterproof
The performance of alarm, life and reliability have transcendency promotion.
