Description

Technical Field

[0001] This utility model belongs to the field of filter technology, specifically relating to a filter adapted to bending conditions. Background Technology

[0002] Some existing air filters require bending during installation due to space constraints and assembly requirements. However, this process has drawbacks: the bent area lacks a support frame. This causes the filter media to stick together after bending, significantly reducing the effective filtration area and efficiency, thus failing to fully utilize the media's filtration capacity. Furthermore, the bent filter's positioning is unstable, making it prone to displacement due to vibration or stress during subsequent use. This not only affects filtration performance but may also interfere with the normal operation of the fuel pump. In addition, the reduced filtration area decreases the space for impurities to adhere to the filter media, leading to rapid clogging of the pores. This prevents the filter from maintaining its designed filtration accuracy for extended periods, necessitating frequent replacements. This increases operating costs, reduces equipment efficiency, and may even increase system energy consumption due to filter failure.

[0003] In conclusion, the structure and arrangement of the frame need to be redesigned to reduce the filter's contact area. Utility Model Content

[0004] The purpose of this invention is to provide a filter that is adapted to bending conditions, which can reduce the contact area and promote media flow.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a filter adapted to bending conditions, comprising a filter body and a filter screen frame disposed on the filter screen of the filter body, the filter screen frame comprising a first frame and a second frame that are not connected to each other, the first frame being located on the filter body near the interface member, and the second frame being located on the filter body away from the interface member; the first frame having a plurality of first support portions extending toward the second frame, the second frame having a plurality of second support portions extending toward the first frame, the first support portions and the second support portions being staggered and their ends being coplanar or staggered at the bending area of ​​the filter screen.

[0006] Furthermore, the first and second skeletons are injection molded onto one side of the filter screen.

[0007] Furthermore, the second frame also has a third support portion and a fourth support portion, the second support portion being connected to one side of the third support portion, and the fourth support portion being provided in a plurality of units and connected to the other side of the third support portion.

[0008] Furthermore, the end of the second support portion is provided with a curved surface, and the curved surface is tangent to its bottom surface.

[0009] Furthermore, the top surface of the end of the second support portion is provided with an avoidance notch.

[0010] Compared with the prior art, the beneficial effects of this utility model are: 1. Improved Positioning Stability: The cross-shaped frame at the bend provides stable positioning support for the filter after bending, ensuring that the filter maintains the correct position during installation and use, preventing displacement and guaranteeing stable operation of the filtration system. This also reduces interference with the normal operation of the fuel pump caused by positioning issues. 2. Extended Service Life: By increasing the filtration area, the filter media pores are less prone to rapid clogging, maintaining the designed filtration accuracy for a longer period. This not only reduces the frequency of filter replacement but also lowers operating costs. Simultaneously, the filter media maintaining optimal filtration performance for an extended period also reduces additional energy consumption caused by filter failure. Attached Figure Description

[0013] The technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0014] Example 1: As Figures 1 to 3As shown, this utility model discloses a filter adapted to bending conditions, including a filter body 1 and a filter screen 2 frame disposed on the filter screen 2 of the filter body 1. The filter screen 2 frame is an injection molded part, which is fixed on the filter screen 2 by injection molding process, and plays the role of supporting the filter screen 2.

[0015] An interface piece 4 is provided at one end of the filter body 1 along its length. The filter screen 2 has a split frame structure, including a first frame 5 and a second frame 6 that are not connected to each other. The first frame 5 is located on the filter body 1 near the interface piece 4, and it can be integrally formed with the interface piece 4 or manufactured separately. The second frame 6 is located on the filter body 1 away from the interface piece 4. The first frame 5 has two first support portions 7 extending toward the second frame 6, and the second frame 6 has three second support portions 8 extending toward the first frame 5. The first support portions 7 and the second support portions 8 are staggered, and their ends are coplanar or staggered at the bending area 9 of the filter screen 2. In this example, as... Figure 3 As shown, in the width direction, a first support portion 7 is located between two adjacent second support portions 8. In the length direction, the ends of the first support portion 7 and the ends of the second support portions 8 overlap, with an overlap area dimension D of 0.2 mm. This way, when the filter body 1 is bent at the ends of the first support portion 7 and the second support portion 8, the ends of the support portions provide support for a portion of the bent filter screen 2, preventing the upper and lower surfaces of the filter screen 2 from completely contacting each other, thus ensuring the flow of the medium within the filter body 1. As a preferred embodiment, the first frame 5 and the second frame 6 are injection molded onto one side of the filter screen 2. The filter screen 2 is formed by folding and welding a single piece of mesh fabric. Before folding, the frames are fixed to the same surface using injection molding, facilitating subsequent folding and welding operations.

[0016] As a preferred embodiment, the second frame 6 also has a third support portion 10 and a fourth support portion 11. The second support portion 8 is connected to one side of the third support portion 10, and two fourth support portions 11 are provided and connected to the other side of the third support portion 10. That is, the third support portion 10 is perpendicularly connected to the second support portion 8 and the fourth support portion 11, and is located between the two, serving as a connection and lateral support.

[0017] Example 2: Figure 4 As shown, unlike Embodiment 1, in this embodiment, the end of the second support portion 8 is provided with a curved surface 12, and the curved surface 12 is tangent to its bottom surface. In this way, after the filter body 1 is bent, the curved surface 12 at the end of the second support portion 8 can fit against the filter screen 2 with a larger area, reducing stress during right-angle contact and extending the life of the filter screen 2. As a preferred embodiment, the top surface of the end of the second support portion 8 is provided with an avoidance notch 13. Figure 5As shown, the purpose of the clearance notch 13 is not to participate in the connection of the filter screen 2. That is to say, when the filter body 1 is bent, the clearance notch will move away from the filter screen 2 to avoid pulling the filter screen 2 and causing damage. This allows the end of the second support part 8 to extend further, increase the overlapping area, and further avoid the upper and lower surfaces of the filter screen 2 from contacting each other and affecting the flow of the medium.

[0018] As can be seen, the above solutions and methods not only stabilize the positioning area after bending, but also increase the filtration area by improving the skeleton structure. Impurities have more space to adhere, and the pores of the filter material are not easily blocked quickly. This allows the filter to maintain the designed filtration accuracy for a long time, thereby reducing system energy consumption and extending the service life of the filter.

[0019] Any aspects of this utility model not described in detail are well-known technologies to those skilled in the art.

[0020] Finally, it should be noted that the above specific embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to the embodiments, those skilled in the art should understand that modifications and equivalent substitutions can be made to the technical solution of this utility model without departing from the spirit and scope of the technical solution of this utility model, and all such modifications and substitutions should be covered within the scope of the claims of this utility model.
