Description

[Technical field]

[0001] The invention relates to the technical field of oil pans, in particular to the technical field of an oil pan capable of automatically detecting engine oil. [Background technology]

[0002] The oil pan is the lower half of the crankcase, also known as the lower crankcase. Its function is to seal the crankcase and serve as the outer shell of the oil tank to prevent impurities from entering. It also collects and stores the lubricating oil flowing back from the friction surfaces, dissipates some heat, and prevents the lubricating oil from oxidizing. Engine oil, or engine lubricating oil, is composed of two parts: base oil and additives. It can lubricate and reduce friction, assist in cooling, seal and prevent leakage, prevent rust and corrosion, and reduce shock and buffer. It is known as the blood of the car. If the engine oil is not replaced for a long time, there will be the following problems: 1. The lubricating effect of the engine oil is reduced, causing debris to be generated by friction between metal parts, and then impurities such as carbon deposits are generated after combustion, which accumulate between the engine parts and cause harm to the operation of the engine; 2. The engine oil becomes watery, the viscosity changes, and the sealing effect is lost; 3. The engine oil deteriorates, the heat absorption and thermal conductivity properties change, resulting in a significant reduction in the heat dissipation function.

[0003] At present, people need to open the hood and pull out the dipstick every once in a while, then insert the oil detection probe into the inner cavity of the crankcase along the dipstick insertion hole to detect the oil, so as to determine whether the oil needs to be replaced, and then insert the dipstick back into the dipstick insertion hole after the detection. The whole process is troublesome and easy to dirty the hands and clothes of the car owner, causing many people to delay oil detection and reduce the detection frequency. [Summary of the invention]
