Description

Automatic drainage diesel filter

Technical Field

The utility model relates to the technical field of diesel engine filters, in particular to an automatic drainage diesel filter.

Background

The main stream of the market is still the fuel vehicle type with six national emission standards, and the market demand of the diesel filter is strong. The existing diesel filter for the low-pressure oil way consists of a shell, a filter element, a pollution discharge screw plug, a filter seat, a manual pump or an electric pump. Impurities and water in the diesel oil sink into a water collecting cup at the bottom of the shell, and are periodically discharged by a manually operated pollution discharge screw plug.

The prior art scheme is that the water collecting cup at the lower part of the diesel filter shell is made into a transparent water collecting cup, and a driver can regularly judge whether to drain water through a pollution discharge screw plug by observing the volume of water in the water collecting cup. That is, the diesel filter on the market at present basically cannot realize intelligent drainage.

At present, the conventional fuel vehicle type commonly uses a mode of manually opening a drain valve for draining water, so that the situation that water cannot be drained in time is easy to occur, and the situation that the drain valve is not easy to open is also caused.

Disclosure of Invention

In order to overcome the defects of the prior art, the utility model aims to provide an automatic drainage diesel filter so as to solve the problem that the drainage valve is manually opened and the timely drainage is not easy to happen.

Therefore, the utility model provides an automatic drainage diesel filter, which comprises a diesel filter main body, a whole vehicle ECU control wiring harness, an electromagnetic valve, a capacitive water level sensor and a CAN signal transmission line; the electromagnetic valve is detachably and fixedly connected with the water outlet of the diesel filter main body, and the electromagnetic valve is in signal connection with the whole vehicle ECU through the whole vehicle ECU control wiring harness; the capacitive water level sensor is arranged outside the water storage chamber of the diesel filter main body and is positioned at the highest water level, and the capacitive water level sensor is in signal connection with the whole vehicle ECU through the CAN signal transmission line.

Further, the water outlet is designed into an internal thread, and one end connector of the electromagnetic valve is designed into an external thread.

Furthermore, quick connectors are respectively arranged at two ends of the whole vehicle ECU control wiring harness, and the whole vehicle ECU and the electromagnetic valve are respectively connected with the whole vehicle ECU control wiring harness through the quick connectors.

According to the automatic drainage diesel filter provided by the utility model, the electromagnetic valve is connected with the water outlet of the diesel filter main body, so that the electric control is realized; the capacitive water level sensor is arranged outside the water storage chamber of the diesel filter main body, a CAN signal transmission line is used for transmitting a water level signal to the whole vehicle ECU, and the whole vehicle ECU controls the electromagnetic valve to be opened and closed after acquiring the water level information, so that automatic water drainage is realized.

In addition to the objects, features and advantages described above, the present utility model has other objects, features and advantages. The present utility model will be described in further detail with reference to the drawings.

Drawings

The accompanying drawings, which are included to provide a further understanding of the utility model and are incorporated in and constitute a part of this specification, illustrate embodiments of the utility model and together with the description serve to explain the utility model. In the drawings:

description of the reference numerals

1. A diesel filter body; 2. the whole vehicle ECU controls the wire harness; 3. an electromagnetic valve; 4. a capacitive water level sensor; 5. CAN signal transmission line.

Detailed Description

It should be noted that, without conflict, the embodiments of the present utility model and features of the embodiments may be combined with each other. The utility model will be described in detail below with reference to the drawings in connection with embodiments.

As shown in fig. 1, the automatic drainage diesel filter of the present utility model includes: the diesel filter comprises a diesel filter main body 1, a whole vehicle ECU control wiring harness 2, an electromagnetic valve 3, a capacitive water level sensor 4 and a CAN signal transmission line 5.

Specifically, the outlet of diesel oil filter main part 1 designs into the internal thread, and the one end interface of solenoid valve 3 designs into the external screw thread, realizes the combination of both through the cooperation of internal and external screw threads, and when the solenoid valve became invalid, can manually unscrew the solenoid valve and accomplish the drainage, prevent to lead to the fact unable drainage and need change whole diesel oil filter because of the solenoid valve damages, at this moment only need change solenoid valve 3 can, whole car ECU control pencil 2 uses quick connector to connect whole car ECU and solenoid valve 3, make things convenient for the dismantlement of spare part.

The capacitive water level sensor 4 is arranged outside the water storage chamber of the diesel filter main body 1, and the capacitive water level sensor 4 is positioned at the highest water level and used for detecting the water level, the capacitive water level sensor 4 is provided with a CAN signal transmission line 5, and the CAN signal transmission line 5 is connected with the whole vehicle ECU by using a quick connector, so that the installation and the disassembly are convenient.

The capacitive water level sensor 4 has the advantages that the sensor does not need to be in contact with liquid, the influence caused by liquid corrosion can be effectively reduced, the capacitive water level sensor 4 is very sensitive, can react to water level change quickly and effectively, and the installation is very convenient.
