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] After the two heating plates are connected in parallel with the temperature controller, they are installed in the housing and the PTC heating plate and the two electrode plates are pressed against the support column of the housing with screws and spring washers to form a heater assembly. The two leads of the module are led out from the wiring port through two electrode poles, one of the pole poles is connected in series with the bimetallic temperature controller and then used as the positive connection of the external power supply through a connecting piece, and the other pole is extended out as the negative connection of the external power supply . The two electrode columns are smashed into the connector through interference fit, so as to connect to the vehicle power supply, which can be easily docked with the body harness.

[0038] When the diesel is flowing through the filter, the diesel will fill the entire filter tank. First, the metal temperature sensor of the temper...

Embodiment 2

[0041] Connect multiple heating plates in parallel, and then connect them in series with the temperature control, and put them into the shell, and use screws and spring washers to press the PTC heating plate and the two electrode plates on the supporting column of the shell to form a heater assembly . The other structure and connection relationship are the same as the technical solution in the first embodiment 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 with screws, and install the two electrode columns of the heater assembly into the connector integrated with the housing through interference fit, and then connect the vehicle power supply . The two electrodes of the heater assembly are then potted with epoxy resin after interference fit. The above two sealing methods are used for double protection, which is safer. It not only ensur...

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 diesel vehicle fuel filtration. Background technique [0002] In order to meet the requirements of energy saving and emission reduction in our country, more and more vehicles use diesel engines on the market. Automobile experts said that compared with gasoline vehicles, diesel vehicles have the advantages of energy saving, environmental protection, robustness, 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 heat conversion efficiency of diesel engines can reach up to 45%, which is 50% higher than that of gasoline engines with the same displacement, so the fuel consumption is much lower than gasoline engines. On the other hand, because the diesel engine is compression-ignited rather than ignited, there is no high-voltage line, spark plug, distributor, ignition system, etc., and there will be no failure o...
