Abstract
The invention relates to an early warning system of an engine. The early warning system of the engine is provided with an air filter. The air filter comprises a shell body and a filtering core, an air channel is arranged inside the shell, and the filtering core is arranged on the air channel. 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 motor car engine early warning system.
Background technique
Along with the raising of people's living standard, automobile use in daily life is more and more general.Yet existing automobile in use still can run into some problems once in a while.
For example in the heavy rain sky, some road surfaces can form ponding, if the chassis of automobile is low, that automobile is by the puddle time, and careless slightly just might have water to enter in cylinder.Due to the incompressibility of water, after water enters cylinder, motor in operation process, just might cause connecting rod bending or fracture, piston breakage or cylinder block puncture by connecting rod etc.After water inflow of the engine, if automobile continues operation, light engine misses are heavy may cause the motor damage.And the damage maintenance of these elements of motor or renewal cost are very expensive.
Summary of the invention
In view of above-mentioned condition, but be necessary to provide a kind of can be before water inflow of the engine the motor early warning system of reminding user just.
A kind of motor early warning system, it has air-strainer.Air-strainer comprises housing and filter core, has gas channel in housing, and filter core is located on the gas channel of housing.The motor early warning system also comprises detective device, and detective device comprises sensor and caution element, and sensor is located on housing and near gas channel, the caution element is electrically connected to sensor.
Above-mentioned motor early warning system comprises detective device, and when it used, if there is moisture to enter air-strainer, sensor can carry out sensing to moisture.When sensor senses moisture, the caution element that is connected with sensor can send alarm signal, and the reminding user air-strainer has entered moisture, and automobile need be stopped using, thereby can avoid moisture to enter into again the motor of automobile, prevent that motor from damaging.
Description of drawings
Fig. 1 is the schematic diagram of the motor early warning system of the embodiment of the present invention.
Embodiment
Below in conjunction with drawings and Examples, motor early warning system of the present invention is described in further detail.
See also Fig. 1, the motor early warning system 100 of the embodiment of the present invention has air-strainer 10.Air-strainer 10 comprises housing 12 and filter core 14.Housing 12 comprises top 122, bottom 124 and is formed at the interior gas channel 126 of housing 12.Top 122 and bottom 124 can together with form housing 12, and be surrounded by cavity between top 122 and bottom 124.Can be formed with suction port 1222 on top 122, be formed with air outlet 1242 on bottom 124.Suction port 1222, the cavity that surrounds between air outlet 1242 and top 122 and bottom 124 consists of gas channel 126.Air 101 flows to motor through gas channel 126.Filter core 14 is located on the gas channel 126 of housing 12.And motor early warning system 100 also comprises detective device 20.Detective device 20 comprises sensor 22 and caution element 24.Sensor 22 is located on housing 12 and close gas channel 126.Caution element 24 is electrically connected to sensor 22.
During use, if there is moisture to enter air-strainer 10, sensor 22 can carry out sensing to moisture.When sensor 22 senses moisture, the caution element 24 that is electrically connected to sensor 22 can send alarm signal, and reminding user air-strainer 10 has entered moisture, and automobile need be stopped using, thereby can avoid moisture to enter into again the motor of automobile, prevent that motor from damaging.
Specifically in the present embodiment, sensor 22 can comprise electrode (figure is mark not).Can be provided with in electrode and meet the water conductive material.Meeting the water conductive material and can be the electrolyte crystal, is for example acid, alkali or salt.Be the cost and the raising usability that reduce motor early warning system 100, the electrolyte crystal is preferably sodium chloride.
When being provided with in electrode when meeting the water conductive material, when not having moisture to enter electrode, can not conducting between the electrode of sensor 22, the caution element 24 that therefore is electrically connected to sensor 22 does not have the alarm signal generation; And when moisture entered electrode, the electrode of sensor 22 can form conducting, and the caution element 24 that therefore is electrically connected to sensor 22 can produce and send alarm signal with the caution user.Specifically, be the electrolyte crystal when meeting the water conductive material, when not having moisture to enter electrode, the electrolyte crystal is solid, and it can not make and form conducting between electrode, and the caution element 24 that therefore is electrically connected to sensor 22 does not have alarm signal to produce; And when moisture entered electrode, the electrolyte crystal was ionized by moisture, and the ion that generation can move freely makes and forms conducting between electrode, and the caution element 24 that therefore is electrically connected to sensor 22 can produce and send alarm signal with the caution user.
Especially, in the present embodiment, sensor 22 is belows of being located at filter core 14, and on the bottom 124 of housing 12.
In addition, be appreciated that for ease of changing the interior chance water of sensor 22 conductive material, can also be provided for changing the more converting mechanism of meeting the water conductive material on the electrode of sensor 22.More converting mechanism can be by cover plate and hole formation for this.
the above, it is only preferred embodiment of the present invention, be not that the present invention is done any pro forma restriction, although the present invention discloses as above with preferred embodiment, yet be not to limit the present invention, any those skilled in the art, within not breaking away from the technical solution of the present invention scope, when the technology contents that can utilize above-mentioned announcement is made a little change or is modified to the equivalent embodiment of equivalent variations, in every case be not break away from the technical solution of the present invention content, any simple modification that foundation 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.
