Technical Field

[0001] The utility model relates to the technical field of oil level sensors, in particular to a novel oil level sensor resistant to ethanol fuel. Background Art

[0002] A fuel level detector is a device used to measure the oil level in a fuel tank or oil tank. A fuel level detector is often installed inside some fuel tanks to detect the oil level inside the tank.

[0003] An oil level sensor of an automobile fuel pump bracket assembly is disclosed in publication number CN217442633U. Although the utility model realizes rapid fixation of the mounting plate by arranging a mounting plate, a telescopic groove, a memory spring, a connecting block and an extrusion plate, it greatly improves the installation efficiency and realizes the feature of easy installation and disassembly of the oil level sensor.

[0004] However, the new ethanol fuel-resistant fuel level sensor has the following disadvantages: since manual operation is required to detect the fuel tank fuel level, the fuel level detector may result in a long response time. This delay may become a disadvantage when quick action is needed to avoid fuel tank overflow or fuel shortage. Summary of the invention

[0005] The technical problem solved by the utility model is to provide a new type of ethanol fuel-resistant oil level sensor which is highly practical, can be simply operated and has a relatively simple structure. It solves the problem raised in the above background technology that the oil level detector may cause a long response time due to the need for manual operation to detect the oil level in the fuel tank. This delay may become a disadvantageous factor when quick action is needed to avoid fuel tank overflow or fuel shortage.

[0006] To achieve the above objectives, the utility model is implemented through the following technical solutions: a new type of oil level sensor resistant to ethanol fuel, including a positioning plate, a main rod passing through the interior of the positioning plate, a floating ball slidably connected to the surface of the main rod, a microcontroller threadedly connected to one side of the main rod surface, the microcontroller is electrically connected to the power supply end of the floating ball, the top surface of the microcontroller is electrically connected to a communication module, and the top of the main rod is fixedly connected to an injection head.

[0007] Optionally, the interior of the injection head is plugged into the interior of the main rod, and the bottom of the injection head is fixedly connected to a power supply box.

[0008] Optionally, a battery for providing power is disposed inside the power supply box, and a card is threadedly connected to one side of the power supply box.

[0009] Optionally, a sealing ring is fixedly connected to the bottom of the main rod, and a connecting piece is fixedly connected to the bottom of the sealing ring.

[0010] Optionally, the top surface of the positioning plate is provided with positioning holes in a circular array at equal intervals, and a gasket is fixedly connected to the middle of the top surface of the positioning plate.

[0011] Optionally, a waterproof pad for increasing waterproofness is sleeved on the outer surface of the communication module, and a sealing ring is sleeved on one end of the injection head.

[0012] The utility model provides a novel ethanol fuel resistant oil level sensor, which has the following beneficial effects:

[0013] 1. This new type of ethanol fuel-resistant oil level sensor, through the setting of floating ball, main rod and positioning plate, when the staff needs to measure the oil level, the positioning plate and main rod can be installed inside the oil tank to be detected. When the staff transports fuel into the oil tank, the fuel will drive the floating ball to rise, making it more convenient for the staff to detect the oil level of the oil tank and avoiding the occurrence of fuel overflow inside the oil tank.

[0014] 2. This new type of ethanol fuel-resistant oil level sensor, through the setting of a microcontroller, a communication module and a floating ball, can detect the oil level through the floating ball when the staff needs to remotely detect the oil level inside the tank. The floating ball converts the detection height signal into an electrical signal and transmits it to the microcontroller. The microcontroller receives the electrical signal and converts it into a signal that can be received by the communication module. Then the communication module transmits the signal to the staff's equipment, thereby facilitating the staff to remotely detect the oil level in the tank. BRIEF DESCRIPTION OF THE DRAWINGS
