Description

Technical Field

[0001] The utility model relates to the field of vehicles, and in particular to a filter, a vehicle chassis and a vehicle. Background Art

[0002] Filter refers to an accessory that filters impurities through a filter element, generally referring to a vehicle filter. Filters are divided into oil filters, fuel filters, air filters, air conditioning filters, etc. according to different filtering functions. There are three types of filters in the engine: air, oil, and fuel, generally called three filters, plus the air conditioning filter, commonly known as four filters, which are responsible for filtering the lubrication system, the medium in the combustion system, the engine intake system, and the cabin air circulation system. Fuel filters are divided into three categories: diesel filters, gasoline filters, and natural gas filters. They are generally connected in series on the pipeline between the fuel pump and the throttle body oil inlet. They can remove solid impurities such as iron oxide and dust and water contained in the fuel, prevent the fuel system from being blocked, reduce mechanical wear, ensure stable operation of the engine, and improve reliability. However, in low temperature seasons, the viscosity of the fuel (especially diesel) increases, the fluidity is poor, and there is a problem of blocking the oil circuit, resulting in poor fuel atomization and incomplete combustion, which in turn makes it difficult for the engine to start cold and cannot operate normally.

[0003] Existing filters often install a heating device inside the filter element of the filter to heat the fuel in the filter. However, the filter structure is relatively complex, and a seal needs to be provided between the heating device and the filter housing, which is costly to install and difficult to maintain.

[0004] Therefore, this field needs a new technical solution to solve the above problems. Summary of the invention

[0024] Continue to see Figure 1, the filter seat 1 is arranged at one end of the filter housing 2, and is used to connect the oil inlet device and the oil using device. An oil inlet 11 and an oil outlet 12 are arranged on the filter seat 1, and the oil inlet 11 and the oil outlet 12 are arranged relatively. Further, an electric pump 3 is arranged on the filter seat 1, and the electric pump 3 is fixed on the side of the filter seat 1 away from the filter housing 2. Specifically, the electric pump 3 is connected to the oil outlet 12. When the electric pump 3 is working, the fuel is sucked into the filter from the oil inlet 11 under the negative pressure of the electric pump 3, and after being filtered in the filter, it is pumped to the oil outlet 12 by the electric pump 3. Further, after the vehicle is started, the electric pump 3 stops working after running for a period of time to exhaust the air in the pipeline, assist the engine start, improve the system start efficiency and stability, and reduce the operating burden. Further, a temperature controller 5 is arranged at the oil outlet 12, and the temperature controller 5 is used to detect the temperature of the fuel at the oil outlet 12.

[0025] Continue to see Figure 1 In one or more embodiments, the filter housing 2 is roughly cylindrical. One end of the filter housing 2 is sealed and connected to the filter seat 1, so that the two cooperate to form a cavity for accommodating the filter element. An oil inlet channel and an oil outlet channel are formed in the cavity, the oil inlet channel is connected to the oil inlet 11, and the oil outlet channel is connected to the oil outlet 12.
