Description
Technical field
The utility model is related to a kind of immersion type air filters to block alarm.
Background technology
By using for a long time, cartridge surface can adhere to a large amount of dusts, increase the air inlet of air cleaner air cleaner
Resistance, intake resistance increase can cause engine charge insufficient, and engine will appear oil consumption and the situations such as increase, is short of power.It is empty
Filtration resistance plug alarm is exactly to carry out the parts of prompt alarm when intake resistance increases to setting value.Existing air filter obstruction
Alarm does not have water-proof function, is easy to cause alarm to intake at rainy season or carwash, to cause alarm fault alarm
Situation brings unnecessary puzzlement and complaint to user；
In addition the shell of existing air filter obstruction alarm is equipped with the micropore for balancing inner and outer air pressure, due to micropore
Setting, affects the water resistance of single unit system.
Utility model content
The utility model provides a kind of good water-proof effect, can soak to solve shortcoming in the prior art
Continue the immersion type air filter obstruction alarm of normal work afterwards.
In order to solve the above technical problems, the utility model adopts the following technical solution：A kind of immersion type air filter obstruction alarm
The top of device, including outer housing, outer housing is equipped with waterproof connector, and the direction radially outside of waterproof connector offers installation
Hole, waterproof ventilated membrane is equipped in the mounting hole of waterproof connector, and the bottom of outer housing is equipped with gas port, is arranged in shell intracoelomic cavity
The diaphragm and the microswitch above diaphragm acted due to have at a gas port air pressure change is equipped in outer housing micro- for triggering
The trigger unit of dynamic switch, is equipped with spring between trigger unit and outer housing.
Microswitch is waterproof micro switch.
Waterproof connector is molded, and is tightly connected by sealing ring between waterproof connector and outer housing.
Waterproof ventilated membrane is connected in the mounting hole of waterproof connector by welding.
The adjusting nut for adjustment spring pretightning force is additionally provided in outer housing, the lower part of outer housing is equipped with filter.
Using above-mentioned technical proposal, the utility model has the advantages that：When the utility model is used, by waterproof
Connector is connect with car alarm system circuit, and gas port is connected with pipeline at the gas outlet of air cleaner, in air cleaner
When normal operating conditions, the negative pressure in air cleaner is very low, and diaphragm does not act, anti-due to being equipped on waterproof connector
Water ventilated membrane, since waterproof ventilated membrane has ventilative and fluid-tight function, the air pressure and the external world in waterproof connector are big
Air pressure is equal, and prevents extraneous water from entering shell intracoelomic cavity, when the filter core of air cleaner obstruction, in air cleaner
Filtered pressure reduces and is less than the air pressure in outer housing above diaphragm, therefore diaphragm generation downwards is acted and triggered anti-
Water microswitch, to car alarm system circuit communication, alarm equipment alarm；The use of the utility model waterproof connector can be with
It avoids or reduces water to penetrate into outer housing through connector, to influence the normal work of the utility model, but even if has water
Into in outer housing, due to the setting of waterproof ventilated membrane and the setting of waterproof micro switch, waterproof ventilated membrane, which has, breathes freely not
Permeable property, thus waterproof ventilated membrane ensure that the air pressure in outer housing above diaphragm always with external atmosphere pressure phase
Deng even if there being water in outer housing, the operation of integral device will not be influenced.
In conclusion the structure design of the utility model is reasonable, solves in obstruction alarm in the prior art and enter water just
It is the problem of failing, highly practical.
Description of the drawings
Fig. 1 is the sectional view of the utility model；
Fig. 2 is the structural schematic diagram of the utility model.
Specific implementation mode
As depicted in figs. 1 and 2, the immersion type air filter of the utility model blocks alarm, including outer housing 1, outer housing 1
Top is equipped with waterproof connector 2, and the direction radially outside of waterproof connector 2 offers mounting hole, the installation of waterproof connector 2
Waterproof ventilated membrane 3 is installed, the bottom of outer housing 1 is equipped with gas port 4, and outer housing is provided in 1 inner cavity because of air pressure at gas port 4 in hole
The diaphragm 5 and the microswitch 6 above diaphragm 5 of variation and action, there are two pin, two pins point for the tool of microswitch 6
It is not connected with the conducting wire for accessing automobile circuit, the trigger unit for triggering microswitch 6, trigger unit are equipped in outer housing 1
It is equipped with spring 7 between outer housing 1, the adjusting nut 8 for 7 pretightning force of adjustment spring, outer housing 1 are additionally provided in outer housing 1
Lower part be equipped with filter 9.
Microswitch 6 is waterproof micro switch 6.
Waterproof connector 2 is by being molded, the connection for coordinating vehicle circuitry, between waterproof connector 2 and outer housing 1
It is tightly connected by sealing ring.
Waterproof ventilated membrane 3 is connected to by welding in the mounting hole of waterproof connector 2.
When the utility model is used, waterproof connector 2 is connect with car alarm system circuit, waterproof in the present embodiment
Connector 2 uses AMP connectors, gas port 4 to be connected with pipeline at the gas outlet of air cleaner, is worked normally in air cleaner
When state, the negative pressure in air cleaner is very low, and diaphragm 5 does not act, due to being equipped with waterproof and breathable on waterproof connector 2
Film 3, since waterproof ventilated membrane 3 has ventilative and fluid-tight function, the air pressure in waterproof connector 2 and external atmosphere pressure
It is equal, and prevent extraneous water from entering shell intracoelomic cavity, when the filter core of air cleaner obstruction, after the filter in air cleaner
Pressure reduce and be less than positioned at the air pressure of 5 top of diaphragm in outer housing 1, therefore 5 downward generation of diaphragm acts and pushes triggering
Portion, trigger unit trigger waterproof micro switch 6, to car alarm system circuit communication, alarm equipment alarm；The utility model waterproof
The use of connector 2 can avoid or reduce water and be penetrated into outer housing 1 through connector, to influence the normal of the utility model
Work, but even if there is water to enter in outer housing 1, due to the setting of waterproof ventilated membrane 3 and the setting of waterproof micro switch 6,
Waterproof ventilated membrane 3 has the property of permeable watertight, therefore waterproof ventilated membrane 3 ensure that in outer housing 1 positioned at 5 top of diaphragm
Air pressure is equal with external atmosphere pressure, even if outer housing 1 has water, will not influence the operation of integral device.
The present embodiment not makes any form of restriction the shape of the utility model, material, structure etc., every foundation
The technical essence of the utility model belongs to this reality to any simple modification, equivalent change and modification made by above example
With the protection domain of new technique scheme.
