The invention discloses an automatic sensor switch for water shortage and excess temperature of a water cooled engine. The automatic sensor switch comprises a shell, a gasket, a force transmission unit and a circuit board, wherein the housing includes a chamber containing expanding gas; the gasket seals the chamber; the force transmission unit extends towards the direction of a central section of the gasket from inside of the housing; the circuit board is provided with a first wiring terminal, a second wiring terminal and a third wiring terminal; a pressure sensing element capable of automatically resetting is fixed on the third wiring terminal, and is arranged above the force transmission unit; and the pressure sensing unit is oppressed by the force transmission unit, so that the second wiring terminal and the third wiring terminal, and the first wiring terminal and the third wiring terminal are sequentially communicated. By adopting the automatic sensor switch disclosed by the invention, the temperature of the engine is controlled by using the heat of the engine, namely periodical temperature monitoring is carried out on the water cooled engine by using the principles that the temperature ascends and the gas pressure increases. The automatic sensor switch is simple in structure and principle, and accurate to monitor; and the fault caused by water shortage and excess temperature of the water cooled engine is greatly reduced.
Description
technical field [0001] The invention relates to a sensor switch, more specifically to an automatic sensor switch for water shortage and overtemperature of a water-cooled engine and an alarm and flameout protector thereof. Background technique [0002] A water-cooled engine is an engine that uses water or antifreeze with water as the main component as the cooling medium. The water-cooled engine casts some passages that can circulate cooling medium on the inner wall of its cover body and cylinder head, and is provided with a special radiator outside the engine body. The cylinder block and cylinder head of the water-cooled engine have good rigidity, low vibration and low noise, so they are adopted by most modern cars. [0003] In order to prevent the cooling water temperature of the water-cooled engine from being too high, the cooling water continuously evaporates and lacks water, and cause engine failure, it is usually necessary to monitor the temperature of the cooling w...
