DETAILED DESCRIPTION OF THE INVENTION

[0001]

The present invention relates to a filter for a vacuum cleaner.

[0002]

2. Description of the Related Art To prevent dust from spilling when disposing of a disposable paper bag filter for a vacuum cleaner, a lid provided on the outer periphery of a filter support of the paper bag filter is closed by a folding line so as to block a suction port. . However, this method has a disadvantage that the size of the support becomes large and that the paper bag filter cannot be sanitarily disposed due to a drawback that it cannot be securely closed.

[0003] In addition, there is an application for a shutter system in which a lid is inserted into a filter support and the lid is pulled out at the time of disposal, but there are disadvantages such as high manufacturing cost, fragility, and difficulty in operation.

Further, in the present invention, there have been applied many examples of the invention which are not practically practical, such as deformation of the filter support from the fold line, leakage of dust, and the use of a fixing sheet to which an adhesive is attached. .

[0005]

As the main body of the vacuum cleaner becomes smaller, the size of the dust case becomes smaller, the filter support cannot be expanded, and a shutter mechanism must be provided in a simple manner.

In view of the above, a filter support is provided with a function of maintaining a sealed state of an opening for preventing dust from being spilled when the paper bag filter is discarded. In order to maintain compatibility with a vacuum cleaner already on the market, the filter support uses an existing filter. It is necessary to ensure the size of the filter, securely seal the dust when the paper bag filter is disposed, and sufficiently secure the strength of the filter support.

[0007]

SUMMARY OF THE INVENTION In order to maintain compatibility with vacuum cleaners already on the market, the filter support must ensure the size of the existing filter, and the means within that constraint are: There is no alternative but to fold the filter support. In this case, it is necessary to ensure the folding in two while ensuring the strength of the filter support.

Therefore, attention was paid to the material of the support. Cardboard is widely used for filter supports. By imparting directionality (rolls) to the fibers when cardboard is manufactured, the cardboard has high strength in the roll direction and is easily broken in the anti-roll direction. Therefore, by using a roll on the support side and perforating the opposite roll, the filter support can be easily bent while securing the conventional strength. When the filter support is bent, the filter support can be held in a bent state by crimping a valve supported on one side into the valve insertion portion so as to sandwich the opening of the paper bag filter. It is essential that the valve insertion part be formed smaller than the width of the valve and be configured to be crimped when the valve is inserted, but when the valve is bent,
There is no problem if the strength is secured so as not to open the filter support.

However, the opening can be easily sealed by the folding line, the valve and the valve insertion portion in the filter support. However, the paper bag is pulled and broken when the filter support is bent. Need to be separated. Therefore, the filter support has a two-layer structure, one is provided with a fixing filter support that directly adheres the paper bag and fixed to the main body, and the other is provided with a lid filter support that is folded to seal the opening, and the two supports are provided. The connection of the body is made of a stretchable member, for example, bellows-shaped paper or rubber, so that no excessive force is applied to the paper bag when the filter support is bent. With such a configuration, the paper bag filter can be sanitarily disposed without tearing the paper bag.

Incidentally, even if the filter support is not made to have a two-layer structure, the filter support and the paper bag can be expanded and contracted by, for example, an elastic member.
The problem can be solved with a simpler configuration by using bellows-shaped paper or rubber.

[0011] By holding the state of the support at the time of bending the support by the method of crimping the valve and fixing it by the valve insertion portion, it is possible to prevent the leakage of dust without a complicated structure. In addition, this can be achieved without changing the size of the support.
