The early warning system of the engine further comprises a sensing and detecting device, the sensing and detecting device comprises a sensing element and a caution element, the sensing element is arranged on the shell and is near the air channel, and the caution element is in electric connection with the sensing element. The early warning system of the engine has the advantages of being capable of warning a user before water enters the engine.
Description
Technical field
The present invention relates to a kind of early warning system, especially a kind of automobile engine early warning system.
Background technology
Along with the raising of people's living standard, automobile use is in daily life more and more general.But existing automobile in use still can run into some problems once in a while.
Such as in heavy rain sky, some road surfaces can form ponding, if the chassis of automobile is low, that automobile is when by puddle, and careless slightly just likely have water to enter in cylinder.Due to the Incoercibility of water, after water enters cylinder, engine in operation process, just likely cause connecting rod bending or fracture, the damaged or cylinder block of piston punctured by connecting rod.After water inflow of the engine, if automobile continues operation, gently then engine misses are heavy then may cause engine damage.And the damage maintenance of these elements of engine or renewal cost very expensive.
Summary of the invention
In view of above-mentioned condition, be necessary to provide a kind of engine early warning system just can reminding user before water inflow of the engine.
A kind of engine early warning system, it has air filter.Air filter comprises housing and filter core, has gas passage in housing, and filter core is located on the gas passage of housing.Engine early warning system also comprises sensing apparatus, and sensing apparatus comprises sensing element and warning element, and sensing element is located on housing and near gas passage, warning element is electrically connected with sensing element.
Above-mentioned engine early warning system comprises sensing apparatus, and when it uses, if there is moisture to enter air filter, sensing element can sense moisture.When sensing elements sense is to moisture, alarm signal can send by the warning element be connected with sensing element, and remind user's air filter to enter moisture, automobile need be stopped using, thus moisture can be avoided to enter into the engine of automobile again, prevent engine damage.
Accompanying drawing explanation
Fig. 1 is the schematic diagram of the engine early warning system of the embodiment of the present invention.
Detailed description of the invention
Below in conjunction with drawings and Examples, engine early warning system of the present invention is described in further detail.
Refer to Fig. 1, the engine early warning system 100 of the embodiment of the present invention has air filter 10.Air filter 10 comprises housing 12 and filter core 14.The gas passage 126 that housing 12 comprises top 122, bottom 124 and is formed in housing 12.Top 122 and bottom 124 can together with form housing 12, and be surrounded by cavity between top 122 and bottom 124.Top 122 can be formed with air inlet 1222, bottom 124 is formed with gas outlet 1242.Air inlet 1222, gas outlet 1242 and the cavity surrounded between top 122 and bottom 124 form gas passage 126.Air 101 flows to engine through gas passage 126.Filter core 14 is located on the gas passage 126 of housing 12.Further, engine early warning system 100 also comprises sensing apparatus 20.Sensing apparatus 20 comprises sensing element 22 and warning element 24.Sensing element 22 to be located on housing 12 and near gas passage 126.Warning element 24 is electrically connected with sensing element 22.
During use, if there is moisture to enter air filter 10, sensing element 22 can sense moisture.When sensing element 22 senses moisture, alarm signal can send by the warning element 24 be electrically connected with sensing element 22, and remind user's air filter 10 to enter moisture, automobile need be stopped using, thus moisture can be avoided to enter into the engine of automobile again, prevent engine damage.
Specifically in the present embodiment, sensing element 22 can comprise electrode (figure does not mark).Can be provided with in electrode and meet water conductive material.Meeting water conductive material and can be electrolyte crystal, such as, is acid, alkali or salt.For reducing the cost of engine early warning system 100 and improving availability, electrolyte crystal is preferably sodium chloride.
When be provided with in electrode meet water conductive material time, when not having moisture to enter electrode, can not conducting between the electrode of sensing element 22, the warning element 24 be therefore electrically connected with sensing element 22 does not have alarm signal to produce; And when moisture enters electrode, the electrode of sensing element 22 can form conducting, the warning element 24 be therefore electrically connected with sensing element 22 can produce and send alarm signal to warn user.Specifically, when chance water conductive material is electrolyte crystal, when not having moisture to enter electrode, electrolyte crystal is solid, and it can not make to form conducting between electrode, and the warning element 24 be therefore electrically connected with sensing element 22 does not have alarm signal to produce; And when moisture enters electrode, electrolyte crystal is ionized by moisture, produce the ion that can move freely and make to form conducting between electrode, the warning element 24 be therefore electrically connected with sensing element 22 can produce and send alarm signal to warn user.
Especially, in the present embodiment, sensing element 22 is provided at the below of filter core 14, and on the bottom 124 of housing 12.
Warning element 24 can be sound warning element or image warning element, and therefore its alarm signal sent can be sound or image.Be appreciated that, the present invention is not as limit, warning element 24 is mainly used for reminding in user's air filter 10 and enters moisture, but it also can have more function, such as can design and make it be connected with engine misses system, when detect enter moisture in air filter 10 time, user can be reminded to note, when there being lasting moisture to enter, engine misses system can being controlled and make engine stop operation.
In addition, being appreciated that for ease of changing chance water conductive material in sensing element 22, the electrode of sensing element 22 can also being arranged for changing the replacing mechanism of meeting water conductive material.This changes mechanism can by cover plate and hole formation.
The above, it is only preferred embodiment of the present invention, not any pro forma restriction is done to the present invention, although the present invention discloses as above with preferred embodiment, but and be not used to limit the present invention, any those skilled in the art, do not departing within the scope of technical solution of the present invention, make a little change when the technology contents of above-mentioned announcement can be utilized or be modified to the Equivalent embodiments of equivalent variations, in every case be do not depart from technical solution of the present invention content, according to any simple modification that technical spirit of the present invention is done above embodiment, equivalent variations and modification, all still belong in the scope of technical solution of the present invention.
