Description
Technical field
The present invention relates to the automobile sensor technical field, be specifically related to a kind of Water temperature sensing alarming device.
Background technique
At present, it is more that sensor technology uses on automobile, and for example crankshaft position sensor is in order to detect the rotating speed of bent axle and motor; Lambda sensor offers ECU as controlling fuel oil or near the reference signal of air ratio optimum value in order to detect the oxygen concentration in exhaust; Intake air temperature sensor offers in order to detect intake temperature the density that the ECU class is calculated air; Cooling-water temperature sensor is in order to detecting the temperature of engine coolant, and offers ECU temperature signal etc.And existing cooling-water temperature sensor adopts sense resistance and magnet-sensitive switch to be bundled together more, and this structure makes sense resistance separate with frame, and the temperature of detection is inaccurate, and reaction is slower, and sensitivity is relatively poor.
Summary of the invention
It is a kind of simple in structure, low cost of manufacture, highly sensitive that technical problem to be solved by this invention is to provide, and can play and detect automobile engine cooling liquid temperature function and the higher device of validity, i.e. a kind of Water temperature sensing alarming device.
Technical problem to be solved by this invention realizes by the following technical solutions:
A kind of Water temperature sensing alarming device comprises frame, and the upper end of described frame is connected with conversion adapter, and its lower end inwall is connected with thermistor; The upper end of described conversion adapter is equipped with two connection-pegs; The upper end of described thermistor is connected with magnet-sensitive switch by a wire, and the top of thermistor is provided with stage clip; The upper end of described stage clip is connected with compact heap; The middle part of described compact heap is provided with through hole; A described wire passes the through hole of described compact heap; The upper end of described magnet-sensitive switch is connected with the lower end of described conversion adapter by No. two wires.
The top of described frame is the hexagon nut shape, and is provided with outside thread in the middle part of it, and described frame is made by copper product, and frame can be connected with the engine coolant case by screw thread like this, and frame 3 can be realized being threaded.
Described compact heap is inverted cone, and described compact heap is made by copper product, adopts copper product, good heat conductivity, the temperature of engine coolant can be passed to thermistor, and by thermistor and magnet-sensitive switch, signal be passed to conversion adapter, by two connection-pegs, signal be spread out of at last.
The invention has the beneficial effects as follows: the present invention has the advantages such as simple in structure, low cost of manufacture and sensitivity height, can play the function that detects the automobile engine cooling liquid temperature, and validity is higher.
Description of drawings
The present invention is further described below in conjunction with drawings and Examples.
