Description

Technical Field

[0001] The utility model relates to the technical field of oil level sensors, in particular to an oil level sensor with an automatic oil-stain removal structure. Background Art

[0002] The oil level sensor is a device used to detect the height of the liquid oil level in a container. It converts the oil level information into an electrical signal output by measuring the capacitance, resistance or other physical quantities of the liquid, thereby realizing real-time monitoring and display of the oil level. The oil level sensor is widely used in the fields of automobiles, construction machinery, generator sets, etc., and is of great significance to ensure the normal operation of equipment and the rational use of oil.

[0003] The existing oil level sensor with automatic oil removal structure still has the following problems. The existing device generally disassembles the oil level sensor for cleaning. For example, Chinese patent CN218511840U discloses a shock-resistant oil level sensor. The utility model protects the oil level sensor by setting a stainless steel sleeve. Under the setting of the back lining, the support and the rubber pad, the lateral buffering of the stainless steel sleeve is preliminarily achieved. Under the action of the buffer cavity and the first spring, the stainless steel sleeve can be further buffered, effectively preventing the oil level sensor from being damaged by lateral impact. Through the action of the plug rod, the plug cylinder, the second spring and the damping piston, the longitudinal buffering of the oil level sensor can be achieved, so that the reliability of the equipment during oil level detection is improved.

[0004] However, as mentioned above, the gasoline in the fuel tank contains impurities, which will accumulate on the sensor over time and clog the filter mesh, affecting the accuracy of the measurement. The oil level sensor needs to be removed to clean it, which is inconvenient and of general practicality. Utility Model Content
