Abstract

The invention discloses a self-heating fuel filter assembly applied to an automobile, which comprises a fuel filter (1) and a filter base (2), wherein the fuel filter is connected with the filter base through a connector component (5), an electric pump (3) is arranged on the filter base and is connected with an oil outlet channel (10) in the filter base, and a heater (6) is arranged on the filter base and at the side edge of the connector component. The electric pump of the invention automatically supplies fuel oil, and ensures sufficient fuel supply when the engine is started. The heater automatically starts a heating mode at the low temperature of 2-7 ℃, and the temperature sensor monitors the oil temperature, so that the wax deposition of fuel oil, particularly diesel oil, in the low-temperature environment is avoided, the viscosity of the diesel oil is reduced, the normal filtration and oil supply of a filter are ensured, the service life of an engine is prolonged, the maintenance cost is reduced, the working efficiency is improved, and the safe running of a vehicle is ensured.

Description

Self-heating fuel filter assembly

Technical Field

The invention relates to a filtering system, in particular to a fuel filter assembly.

Background

At present, a fuel filter assembly is generally in a manual oil pumping mode, fuel such as gasoline or diesel oil is filtered, and before a vehicle is started, an engine is started after the fuel is pumped by manually pressing the manual pump for many times. The device is not provided with a heating device, and has no detection measure for the temperature of the fuel. In cold places in the north, fuel oil has the risks of insufficient oil supply and temporary condensation, and needs to be heated to help the fuel oil to thaw in time so as to start or start a vehicle in time.

SUMMERY OF THE UTILITY MODEL

The invention aims to overcome the defects of the technology and provide a self-heating fuel filter assembly which can heat filtered fuel and supply sufficient fuel in time.

The purpose of the invention is realized by the following technical scheme: the self-heating fuel filter assembly includes fuel filter and filter seat, the fuel filter is connected with the filter seat by means of connecting head component, on the described filter seat an electric pump is mounted, said electric pump is connected with oil outlet channel in the filter seat, and on the described filter seat and at the side of connecting head component a heater is mounted.

And a temperature sensor is arranged on the filter base and at the side edge of the connector assembly. The bottom of the fuel filter is provided with a visual water collecting cup, and the bottom of the visual water collecting cup is provided with a water drain valve. A water level sensor assembly is arranged in the visual water collecting cup.

After the structure of the invention is adopted, the electric pump automatically supplies fuel oil filtered by the fuel oil filter, the heater receives an instruction, the heater automatically starts a heating mode at the low temperature of 2-7 ℃, and the temperature sensor monitors the oil temperature, thereby avoiding the wax deposition of the fuel oil, especially the diesel oil, in the low-temperature environment, reducing the viscosity of the diesel oil, ensuring the normal filtering and oil supply of the filter, prolonging the service life of an engine, reducing the maintenance cost, improving the working efficiency and ensuring the safe running of a vehicle. And after fuel is filtered, the arrangement of the visible water collecting cup and the water level sensor component enables the water level height at the bottom of the filter to be visible, and when the water level height reaches a limit height, an alarm is given to remind a driver of discharging water in time, so that flameout of a vehicle is prevented.

Drawings

The invention is described in further detail below with reference to the figures and embodiments.

FIG. 1 is a schematic structural diagram of the present invention.

Fig. 2 is a side view (upper part) of fig. 1.

Detailed Description

Referring to fig. 1 and 2, the self-heating fuel filter assembly applied to the automobile of the invention comprises a fuel filter 1 and a filter base 2, wherein the fuel filter 1 is connected with the filter base 2 through a connector assembly 5, an electric pump 3 is arranged on the filter base 2, the electric pump 3 (the cavity thereof) is connected with an oil outlet channel 10 (which is communicated with the connector assembly 5) in the filter base 2, and a heater 6 is arranged on the filter base 2 and at the side edge of the connector assembly 5 (close to the fuel filter) to heat the fuel output after filtration. A temperature sensor 4 (which can also be arranged at the side of the heater 6) is arranged on the filter base 2 and at the side of the connector assembly 5, so as to monitor the temperature of the filtered output fuel in real time.

The temperature sensor 4 and the heater 6 are respectively electrically connected with a temperature control device of the vehicle engine. When the vehicle is started to reach a power supply item (power is turned on), namely when the power supply of the engine is started, the electric pump works for 3-5 minutes to automatically pump oil according to the plugging signal instruction, so that the electric pump automatically pumps the fuel oil in the filter, and the normal starting and sufficient oil supply of the engine are ensured. The engine does not need to pump oil when working normally.

The bottom of the fuel filter 1 is provided with a visual water collecting cup 7 (made of transparent organic glass material), and the bottom of the visual water collecting cup 7 is provided with a water drain valve 8. The visible water collecting cup 7 is internally provided with a water level sensor assembly 9 (a part of which can be positioned outside the bottom of the visible water collecting cup). The bottom water level of the fuel filter is visible, when the water level reaches the limit height, the water level sensor assembly 9 transmits an alarm signal to an operation panel in the vehicle to remind a driver of discharging water in time, and the vehicle is prevented from being flamed out.
