Description

DETAILED DESCRIPTION OF THE INVENTION "Field of Industrial Application" The present invention relates to a fluid filter used for filtering intake air into an engine and other arbitrary uses.

``Prior art'' A fluid filter in which a P material is formed into a substantially ring shape with a corrugated longitudinal section, and a sealing flange on the outer circumferential side and a central sealing member on the inner circumferential side are integrally molded with the furnace material using resin is particularly effective. Kaisho 59-261
This method is disclosed in Japanese Patent Publication No. 20 and Japanese Unexamined Patent Publication No. 61-209022. However, the structure in which resin is molded integrally with the furnace material cannot easily accommodate changes in the shape of the sealing flange and central sealing member, and new resin molds must be manufactured. It is not suitable for producing fluid filters of similar shapes.

"Problems to be Solved by the Invention" The present invention has been made to solve the above problems, and provides a fluid filter that can easily accommodate changes in the shape of the center seal member and the outer seal member. The purpose is to provide

"Means for Solving Problems" To achieve the above-mentioned purpose, according to the present invention, first . The second frame is integrally molded'? Provided is a fluid filter comprising a filtration main body, a first sealing member joined to a first frame, and a second sealing member joined to a second frame. .

According to the above configuration, when the shape imitation of the first seal member and/or the second seal member is changed, these first seal members are attached to the frame of the filter body. This can be easily handled by joining the sealing member and/or the second sealing member, for example, by vibration welding, adhesive, or the like.

"Embodiment" According to the first embodiment R of the present invention, the shape of the furnace material of the filter body is a continuous wave shape in longitudinal section.

According to the second embodiment of the present invention, the rod shape of the filter body has a wave-like shape in longitudinal section, and is separated into one or several ridges. As in the first and second aspects, the furnace material having a corrugated longitudinal section may have a continuous waveform or may be separated into one or several ridges, and the present invention is well applicable to either case. be done.

According to the third embodiment rB of the present invention, the shape of the furnace material of the filter body is approximately radial. In this way, the present invention is applicable even when the P material shape is substantially radial.

"Example" Next, an example of the present invention will be described with reference to FIGS. 1 to 11.

1 and 2, the fluid filter 1 has an annular frame 5a on its outer peripheral end, an annular frame 5b on its inner peripheral end, which are integrally molded with resin, and a cross section of the furnace material 6. In order to maintain the waveform shape, radial frames 5c are provided at several locations as necessary, and the filter body 2 is formed to have rigidity as a whole.

- On the outer circumferential side of the filter body 2, a flat annular sealing flange 3 as shown in FIG. 4 is joined at the contact surface by, for example, vibration welding, and in the center as shown in FIG. The disk-shaped center seal member 4 is assembled by joining the contact surfaces thereof by, for example, vibration welding.

In the filter main body 2 shown in FIG. 2, the P material 6 has a continuous wave-shaped longitudinal section. The original shape of 枦+jJ6 is a fan-shaped P material 6° as shown on the left side of FIG. 8, and by folding and curving it into a wave shape, it becomes a ring-shaped furnace material 6 as shown on the right side of FIG. Ring-shaped furnace material 6
End gap 1? f18 is housed in the radial frame 5c and sealed during integral resin molding.

The ring-shaped filter medium 6 is divided in the circumferential direction into P materials 9a, 9b, and 9c, which are obtained by folding and curving a plurality of fan-shaped lacrimal materials 9a', 9b', and 9C' into waveforms, as shown in No. 9rA. In this case as well, the gap 8 at the end of the rod may be accommodated within the radial frame 5c as described above.

The filtration main body 2d shown in FIG. 3 separates the l material 10 into each wave-shaped vertical section. However, it is also possible to separate the P material 10 into multiple peaks. In this case, the original shape of the resin material 10 is an arcuate band-shaped material 10a corresponding to a single pile, as shown in FIG.

This belt-shaped furnace material 10a' is folded in half and curved to obtain one pile of P material 10a, and the required number of piles is obtained in the same manner. In this case, the joining of each pile of P material 10a is done by integrally molding the annular frame 5d in FIG. Place it inside the 5c and seal it. A sealing flange 3 as shown in FIG. 4 is provided on the outer periphery of the rigid r-radial body 2a obtained as described above, and a center sealing flange 3 as shown in FIG. 5 is provided on the inner periphery. A filter body (not shown) is obtained by joining the seal member 4 by, for example, vibration welding.

FIGS. 6(a) to 6(C) show examples of the shape of the sealing flange. The width of the plate annular flange 3 as shown in FIG. 6(a), the height H2 of the trapezoidal flange 3' as shown in FIG. The depth H' of the flange 3'' differs slightly depending on the type of engine to which it is applied, and is determined based on various requirements.

FIG. 7 shows a center seal member 4' having a mounting hole 7 in the center. The height h and the inclination angle θ of the central sealing member 4° are determined according to each cup requirement.

"Operation" In the above configuration, when the filter body 1 according to this embodiment is assembled into an air purifier, the sealing flange 3 is attached to the cap 13 of the air purifier 12 and the case 14, as shown in FIG. In between, through gaskets 15 and 16 respectively,
For example, it is clamped and sealed by a clamp (not shown). The center seal member 4° is sealed between the support frame 17 fixed to the case 14 and the cap 13 via the gasket 18, and is sealed by tightening the medium nut 21 to the stud port 20 implanted in the carburetor 19. It is assembled into the carburetor 19 while maintaining the same. A seal between the air cleaner 12 and the carburetor 19 is obtained by inserting a gasket 22 between them.

In the case of a temporary body for air purifiers, the sealing flange has a width of 3, 3", 3" and a height of H, depending on the condition when installing it to the engine.
Requirements for the filter body 1, such as the depth H', the diameter, height h, and inclination angle θ of the center seal members 4 and 4', or the presence or absence of the mounting hole 7, often differ depending on the engine model.

As in this embodiment, frames 5a, 5b, and 5c made of resin are provided on the inner and outer circumferential sides of the filter bodies 2 and 2a.

A filter body 2.2a''+ is manufactured by integrally molding 5d with the rod members 6 and 10 to give it rigidity, and on this 7f' A body body 2 and 2a, a peripheral seal 7 that meets each FlIC' requirement is made. By creating a structure in which the flanges 3.3', 3'' and the center sealing member 4゜4' are joined together, the flange 3.3' as described above can be removed.
, 3" and the center seal member 4.4', in response to various requests for the flange 3~3" and the center seal member 4.4'.
Since the filter bodies 2 and 2a can be used in common by simply installing a new mold, it is possible to cope with the problem at low cost and with a large degree of freedom.

"Other Embodiments" The present invention is not limited to the details of the structure of the above embodiments. For example, the R members in the filter body are not concentric, but have radial P members 22 as shown in FIG. However, in this case,
Attachment members are joined to the upper and lower frames of the filter body. In addition, the shape of the filter main body does not have to be circular, but may have a substantially concentric circular shape or a substantially radial P-phase shape.
It may be oval, elliptical, polygonal, eccentric circular, or the like.

"Effects" As described above, the fluid transient of the present invention has the following advantages: If the shape and structure of the second seal member is changed, this can be easily changed by joining the first seal member and/or the second seal member to the frame of the filter body. It has the excellent effect of being extremely convenient in producing a small number of transients with a wide variety of similar shapes.
