Description

[Detailed description of the invention] The present invention relates to an air cleaner device for purifying the air sucked by the engine of a motorcycle, and its purpose is to provide a simple structure that improves the air purification rate. .

Conventionally, flexible materials made of foamed resin in the form of a mesh have been used for filters, but because they are so-called single-stage filters and have a uniform mesh, they clog quickly, making it difficult to maintain a cleaning rate over time.

There are cases where multi-stage paper filters such as two-stage or three-stage paper filters are used to good effect in special vehicles used in rally competitions.
There was a demand for a multi-stage, lightweight air cleaner for motorcycles that was inexpensive and made of a material that did not have rigidity for the filter itself.

The present invention has fulfilled this requirement, and is based on a structure in which a retainer is inserted into the filter space by utilizing the flexibility of the airtight foamed resin used for one end face of the filter.

In other words, as shown in Figure 1, foamed resin is detonated using the explosion method
75) etc., the mesh size can be freely selected and the flexible filter is inexpensive.

It is preferable that the first filter 1 has a coarse mesh, usually with a mesh density of 1 mesh per inch, and the second filter 2 has a dense mesh, usually with a mesh density of 5 meshes per inch.

In addition, the device of the present invention includes a flexible end face plate 4.5 in which the foam membrane is not destroyed as an airtight foamed resin 3, cages 6 and 7 made of rigid aggregate, and a box body 14 that encloses the entire body. Hold the filter.

First, the first filter 1 in the form of a strip is bent into a substantially cylindrical shape and then glued or sewn together.

Similarly, a second filter 2 is provided in the inner space of the first filter 1 in a substantially cylindrical shape and has a smaller diameter than the first filter 1, and is positioned substantially concentrically.

Then, end plates 4 and 5 made of airtight foamed resin 3 are adhered to both end faces of the first filter 1 and the second filter 2.

In particular, the gap between the first filter 1 and the second filter 2 is called a filter space 9.

The end plate 4 made of airtight foamed resin 3 has a central hole called a second cut 10 and an annular slit outside it called a first cut 11.

A retainer having a diameter larger than the cut can be inserted through this cut with flexibility.

The first retainer 6 is inserted through the first cut 11, and the second retainer 7 is inserted through the second cut 10.

The air cleaner device is completed by housing the filter in a rigid box 14, generally made of resin, which has at least two or more windows.

By connecting the second cut 10, which is engaged with one of the windows, to the carburetor of the motorcycle, air containing dust enters the box body 14, and large particles of dust are first collected by the first filter 1.
Small particles of dust are collected by the second filter 2, and air that is sufficiently purified is sucked into the engine cylinder.

The collected dust is removed from the box 1 periodically or as needed.
It can be removed by removing it from 4 and washing it off by backwashing (using an air gun or the like to reverse the flow).

At this time, the dust that has fallen from the second filter 2 is in the filter space 9 and is discharged from the first cut 11.

FIG. 2 shows an example in which the outer skins of the first filter 1 and the second filter 2 are grafted with fine hairs, and the collection of dust is effective.

Although the first cut 11 is provided in the end plate 5, the same effect can be obtained.

FIG. 3 shows an embodiment in which the first filter 1 and the second filter 2 are formed into slightly circular trapezoidal shapes, and the same effect as described above can be obtained.

As described above, the present invention can provide a small, lightweight, and inexpensive air cleaner device for motorcycles despite having a two-stage filter structure.

The present invention plays a major role in improving the durability of motorcycles and simplifying maintenance.
