Those skilled in the art can make similar extensions without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0023] Secondly, this utility model is described in detail with reference to the schematic diagrams. When describing the embodiments of this utility model, for ease of explanation, the cross-sectional views illustrating the device structure may be partially enlarged, not adhering to the usual scale. Furthermore, the schematic diagrams are merely examples and should not limit the scope of protection of this utility model.

[0024] To make the objectives, technical solutions, and advantages of this utility model clearer, the embodiments of this utility model will be described in further detail below with reference to the accompanying drawings.

[0025] This utility model provides a common design mechanism for filters. By setting up fuel components and common design components, it achieves a universal design, combines the functions of the original design, optimizes the design in terms of development cost and development speed, realizes interchangeable design of parts, reduces mold development cost, and thus reduces development cost and speed.

[0026] Figures 1-3 The diagram shown is an overall structural schematic of an embodiment of the common design mechanism for filters according to this utility model. Please refer to [link / reference]. Figures 1-3 The main structure of this embodiment includes: a fuel assembly and a common design assembly.

[0027] The fuel assembly is used in conjunction with common design components. Specifically, the fuel assembly includes a housing 11, a fuel pump 12 disposed within the housing 11, a fuel delivery pipe 13 connected to the fuel pump 12, and a fuel storage housing 14 disposed within the housing 11.

[0028] In actual use, the fuel in the oil reservoir 14 is pumped by the fuel pump 12, and thus fuel is supplied to the engine through the fuel line 13.

[0029] The common design components are used for adaptation, sharing parts and reducing the cost of use. Specifically, the common design components include filters 21 symmetrically arranged in the housing 11, oil return pipe 22 connected to one of the filters 21, oil outlet pipe 23 connected to the other filter 21, and steel balls 24 arranged in the oil outlet pipe 23.

[0030] In practical use, the user presses the steel ball 24 into the oil outlet pipe 23, and the steel ball 24 and the oil outlet pipe 23 are sealed by hot riveting technology. At this time, fuel enters the filter 21 from the return pipe 22, circulates and filters in the filter 21, and finally the fuel in the filter 21 enters the ejector 25 under pressure. Then the fuel in the ejector 25 enters the oil reservoir 14 after being filtered by the filter screen 26, replenishing the oil reservoir 14 with fuel. Finally, the fuel pump 12 provides fuel to the engine, thereby ensuring a continuous and clean fuel supply to the fuel system. This structural design, which makes reasonable use of the fuel pump 12 assembly in the same mechanism, and the optimized and universal design of the filter 21, can ensure that the main functional parts do not lose their function, and can also ensure the rational use of the overall space, thereby reducing development costs, accelerating development speed, and bringing high-performance conversion output to enterprises.

[0031] Although the present invention has been described above with reference to embodiments, various modifications can be made and components can be replaced with equivalents without departing from the scope of the present invention. In particular, as long as there is no structural conflict, the features in the embodiments disclosed in this invention can be combined with each other in any way. The lack of an exhaustive description of these combinations in this specification is merely for the sake of brevity and resource conservation. Therefore, the present invention is not limited to the specific embodiments disclosed herein, but includes all technical solutions falling within the scope of the claims.
