Problems solved by technology

[0004] At present, people have put forward many new ideas and different methods to try to solve this problem. Many of the existing patents in our country are related to this aspect, but these are all split or independent, that is, The heating part and the sensor part are divided into two parts or only have the heating function or water level monitoring function, and the split type takes up space and is cumbersome to assemble

Embodiment 1

[0037] The two heaters are connected in parallel and connected in series with the temperature controller, put them into the casing and use screws and spring washers to press the PTC heater and the two electrode sheets on the support column of the casing to form a heater assembly. The two lead wires of the component are drawn out from the wiring port through two electrode columns, one of which is connected in series with the bimetallic temperature controller and then passes through a piece of connecting piece as the positive connection of the external power supply, and the other electrode column is used as the negative connection of the external power supply. . The two electrode columns are smashed into the connector through interference fit to connect to the vehicle power supply, which can be easily connected with the body wiring harness.

[0038] When the diesel oil flows through the filter, the diesel oil will fill the entire filter tank. First, the metal temperature sensing...

Embodiment 2

[0041] Connect multiple heaters in parallel, then connect them in series with the temperature control, put them into the casing, and use screws and spring washers to press the PTC heating sheet and the two electrode sheets on the support column of the casing to form a heater assembly . Other structures and connections are the same as the technical solution in Embodiment 1 to realize fuel heating and water level monitoring at the bottom of the filter tank.

[0042] Specific implementation steps: first, install the heater assembly on the fixing hole of the housing by screw fastening, and then install the two electrode columns of the heater assembly into the connector integrated with the housing through interference fit, and then connect the vehicle working power supply . The two electrodes of the heater assembly are potted with epoxy resin glue after interference fit. The above two sealing methods are used for double protection, which is safer. It not only ensures the firm inst...

Abstract

The invention discloses an integrated type filter fuel oil heating and water level sensing device, and relates to the technical field of diesel vehicle fuel oil filtering. The device comprises a shell. An oil inlet and an oil outlet are formed in the shell. The oil inlet is communicated with an oil leak opening, leading to a filter, in the bottom of the shell. The bottom of the shell is connected with an oil outlet pipe. The oil outlet pipe is communicated with the oil outlet and can be inserted in the filter from an upper cover opening of the filter. A heating assembly is arranged in the oil outlet pipe, and a circuit control module of the heating assembly is arranged in the shell and can be connected with a vehicle-mounted power source through a wire. A water level sensor is arranged at the bottom of the oil outlet pipe and can be connected with a vehicle ECU through a wire. The device is rapid in heat transfer and high in heat efficiency and safety coefficient, the space is saved, heating, temperature control and water level monitoring can be integrated conveniently, and the defects in existing heaters are overcome fundamentally.

Description

technical field [0001] The invention relates to the technical field of fuel oil filtration for diesel vehicles. Background technique [0002] In order to meet the requirements of my country's energy saving and emission reduction, there are more and more vehicles using diesel engines on the market. Auto experts say that compared with gasoline vehicles, diesel vehicles have the advantages of energy saving, environmental protection, strength, safety and durability. On the one hand, the energy density of diesel is higher than that of gasoline. After adopting a series of advanced technologies, the thermal conversion efficiency of diesel engine can reach up to 45%, which is 50% higher than that of gasoline engine with the same displacement, so the fuel consumption is much lower than that of gasoline engine. On the other hand, since diesel engines are compression-ignited rather than ignited, there are no high-voltage wires, spark plugs, distributors, ignition systems, etc., and th...
