Description

Technical Field

[0001] The utility model relates to an installation structure of a fuel heater and a fuel tank, belonging to the technical field of fuel heaters. Background Art

[0002] A fuel heater is a device used to heat the fuel in the fuel tank of a motor vehicle to solve problems such as poor fluidity of fuel (mainly diesel) in a low-temperature environment, resulting in insufficient fuel supply, difficult starting, or incomplete combustion.

[0003] Generally, a fuel heater is directly installed on the fuel tank to heat the fuel in the fuel tank. The existing installation method of a fuel heater and a fuel tank generally adopts a threaded connection installation structure. For example, the publication number is CN209414010U, and the patent name is a fuel heater with a conversion valve, including a connecting body with a protrusion at the lower end of the base. The outer cylindrical surface of the connecting body is processed with an external thread, and the upper end surface of the connecting body is processed with a clamping flap. The outer cylindrical surface of the connecting body is processed with an external thread and the upper end surface of the connecting body is processed with a clamping flap, which is convenient for the connection and installation of the entire fuel heater connecting body and the fuel tank. However, when installing this clamping flap structure with the fuel tank, the fuel tank needs to be processed twice. A round hole corresponding to the connecting body is processed, and a slot corresponding to the clamping flap is processed around the round hole, and then the entire fuel heater connecting body can be installed on the fuel tank. In addition, due to the different thicknesses of the fuel tanks of different vehicle models, and the fuel heaters are generally mass-produced rather than customized, the thickness of the connecting body of the mass-produced fuel heaters cannot fit the installation openings of the fuel tanks of all vehicle models.

[0004] Therefore, it is urgent to propose an installation structure of a fuel heater and a fuel tank to solve the above technical problems. Summary of the Utility Model

The number of the clamping flaps 3 is at least 2. With such a setting, during use, a round hole is processed in the fuel tank, and then the valve body 1 is installed at the round hole of the fuel tank. By screwing the bolt 2, since the bolt 2 is threadedly connected to the clamping flap 3, the clamping flap 3 clamps the fuel tank shell between the clamping flap 3 and the valve body 1, realizing the installation of the fuel heater and the fuel tank. This installation form has the following advantages:

[0027] 1. It reduces the processes of machining external threads on the outer circular surface of the original connector and machining clamping flaps on the upper end surface of the connector in the background art, saving machining costs;

[0028] 2. It reduces the secondary machining process of the fuel tank. There is no need to additionally machine a clamping groove. The installation of the fuel heater and the fuel tank can be realized only by opening a round hole in the fuel tank, also saving machining costs and shortening the installation time;

[0029] 3. The fuel tank shell is clamped between the clamping flap 3 and the valve body 1 by the clamping flap 3. The distance between the clamping flap 3 and the valve body 1 can be adjusted by screwing the bolt 2, so that the valve body can adapt to the requirements of the thickness of fuel tanks of different vehicle models, having the advantage of high adaptability.
