Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an electric vacuum cleaner for sealing a paper bag at the time of discarding a paper bag filter of a filter of a type that collects dust with a disposable paper bag.

[0002]

2. Description of the Related Art Conventionally, a disposable paper bag filter for an electric vacuum cleaner is prevented from spilling dust when it is discarded by discharging a low-priced product without a lid and a high-grade product by integrally discharging the filter to the filter support of the paper bag filter. The provided lid was covered with a folding line so as to cover the folding suction port. The drawbacks were that the support was enlarged and the seal was not reliably sealed.

Another method is to stretch a partially opened rubber film on the suction port, which has the drawbacks of high manufacturing cost and uncertainties.

Many applications have been made for the type of removing the filter when pulling out the filter, and it is effective in the system in which the suction port is arranged at the front end of the cleaner and the support is attached vertically, but in consideration of handleability, it is horizontal. Mainly manufacturing the arrangement, it is not a valid invention in the horizontal arrangement, the drawback is that the shirt does not close when the garbage is full, there is no certainty,
It is easy to break and the cost is high.

In addition, there are many examples of inventions that are not practically applicable, such as the support being deformed from the folds and dust leaking, the adhesive protective sheet not peeling off, and the bag being torn when folded in two with it set.

[0006]

With the recent miniaturization of the cleaner body, the filter support has become smaller and the shutter mechanism cannot be provided integrally.

In order to reduce the size of the support and securely seal and dispose of the dust, the support must be broken, and for that purpose,
It was necessary to solve problems such as the support being deformed from the folds during dust collection to leak dust, the adhesive protective sheet not peeling off, and the bag being torn when folded in two with it set.

[0008]

[Means for Solving the Problems] In order to maintain compatibility with vacuum cleaners already on the market, it is necessary to secure the size of the current filter support, and the means within the constraints are the current ones. There is no choice but to fold the filter support, and in that case it is necessary to secure the strength of the filter support.

In view of this, the method of supporting the filter support and the cardboard, which is the material, have a support on two surfaces facing each other. If folding lines are placed on these two surfaces, the support will be deformed during dust collection work. Therefore, it was confirmed that the problem could be solved by providing a polygonal line on the opposing support part. Also, in order to fold and seal the support more easily than the fold line, pay attention to the material of the support and say that the cardboard has directionality in the fibers in the manufacturing process and the roll eye direction is strong and the anti-roll eye direction is easy to fold. I found a method that has a personality, and by using that character to attach a sewing machine for folding in the direction of the roll eye, even if it can be folded in two, the support side uses the roll eye so that the support strength of the paper bag filter does not decrease. .

In order to maintain the seal of the support body folded in two, the case of using an adhesive and the case of utilizing the deformation of the support are examined, and the method of peeling off the protective sheet of the adhesive is better. We have also devised a method for simplifying it, and a method without using an adhesive.

[0011]

[Function] In order to achieve the certainty of supporting the paper bag filter and the convenience of dust sealing at the time of disposal without increasing the size and cost of the filter support, a method of folding the support in two is considered. By putting it in, folding work becomes easier,
By adding a mechanism to hold the fold, hygiene is improved.

Further, since the folding direction is the roll-eye direction, no force is required for folding, and after folding to accurately fold it from the designated position, it is possible to reliably seal the dust opening by adhesion or folding, Even if dust is thrown away, dust does not scatter.
