Problems solved by technology

[0006] 2. When the sensor is working, the matching alarm light harness is short-circuited due to the bumping of the car
[0007] 3. The supporting alarm lamp and buzzer are damaged, which leads to short circuit of the sensor
[0008] 4. Sensor short circuit caused by other accidental factors
[0009] When the above-mentioned short-circuit occurs, the traditional automotive oil-water separation alarm will burn out and cannot resume normal work because it does not have the short-circuit protection function. and other serious consequences

Abstract

The invention relates to an automobile oil-water separation alarm with a short circuit protection function. The alarm comprises an oil-water separation detection sensor and an alarm indicating lamp externally connected to the oil-water separation detection sensor, wherein the oil-water separation detection sensor comprises a polyamide shell formed at one time, a direct current power supply external interface, an alarm indicating lamp external interface and a power supply ground external interface which are embedded into the top of the shell, an alarm probe embedded into the lower end of the shell, and a short circuit protection circuit embedded into the shell. Through the design of the short circuit protection circuit, the oil-water separation detection sensor quickly detects short circuit change under the adverse conditions that an external load is short-circuited and the like, and cuts off conveyed current in short time, so that the short circuit protection function is realized, and high practicability is achieved.

Description

technical field [0001] The invention relates to an automobile oil-water separation alarm, in particular to an automobile oil-water separation alarm with a short-circuit protection design. Background technique [0002] With the vigorous development of the automobile industry, the application standards of automobile engines have been further improved. Under the overall trend of saving resources and protecting the environment, with the mandatory implementation of Euro III engine standards, the requirements for fuel filtration systems have also been further enhanced. The oil-water separator for automobiles is the most important part of the fuel filter. Its main function is to remove the water in the fuel to reduce the failure of the fuel injector and prolong the service life of the engine. [0003] Under the normal operation of the oil-water separator for automobiles, after the fuel is separated from the oil and water, the clean fuel enters the oil circuit system of the automob...
