Telescopic oil level sensor device

Abstract

At present, an oil level sensor has the defects of poor corrosion resistance, poor size universality, single function and the like, and aiming to solve the problem, the invention provides a telescopicoil level sensor device. The telescopic oil level sensor device comprises a signal cable, a cable interface, an electric appliance box, a mounting flange, a sealing ring, an oil suction pipe connector, an exhaust pipe connector, an oil return pipe connector, an exhaust hole, an oil return pipe, an oil return port, a plug cover, an induction pipe, an oil floater, an oil suction pipe, a filter screen cover, a filter screen and a spring, so that the functions of oil absorption, oil return and oil quantity measurement are integrated; the filter screen cover, the filter screen, the spring and theplug cover form an elastic movable device to realize direct contact with the bottom of the oil tank, so that the sensor device is telescopic and adjustable in length and is suitable for oil boxes withdifferent heights; the oil liquid at the bottom of the oil tank is fully sucked and utilized, the oil liquid at the bottom of the oil tank is circulated and replaced, and fuel waste is avoided, the formation of a bottom oil liquid deposit layer is prevented; and the characteristics of light weight, universality and multiple functions are realized, and a very wide application prospect is achieved.

Description

technical field [0001] The invention relates to an oil level sensor device, in particular to a retractable oil level sensor device, which belongs to the field of oil level sensor design and manufacture. Background technique [0002] The fuel level sensor is an important part of equipment powered by internal combustion engines such as automobiles and ships. Its main function is to detect the remaining fuel in the fuel tank and transmit the signal to the dashboard. At present, the oil level sensor has the following problems and adjustments: First, the oil level sensor is prone to corrosion failure due to its long-term work in the oil and the harsh environment of use. Secondly, the ordinary oil level sensor has a single function and does not have the functions of oil absorption and oil return. Again, the versatility is poor, and it is often necessary to design sensing tubes of different lengths according to different fuel tank heights, thereby producing multiple models of prod...

Problems solved by technology

At present, the oil level sensor has the following problems and adjustments: First, the oil level sensor is prone to corrosion failure due to its long-term work in the oil and the harsh environment of use

Secondly, the ordinary oil level sensor has a single function and does not have the functions of oil absorption and oil return

Again, the versatility is poor, and it is often necessary to design sensing tubes of different lengths according to different fuel tank heights, resulting in multiple models of products

In addition, in order to avoid collision between the fuel level sensor and the bottom of the fuel tank due to vehicle vibration, the length of the sensor is often shorter than the height of the fuel tank, which cannot truly reflect the amount of fuel in the fuel tank, and also makes the oil at the bottom of the fuel tank unusable

For the widely used magnetic switch oil level sensor, the metal sensing tube will have a certain impact on the magnetic float, resulting in a decrease in measurement accuracy
