It should be noted that although it is not the dust collecting filter itself for an electric vacuum cleaner, it is disclosed in Japanese Patent Application Laid-Open No. 50-52
Japanese Patent Publication No. 128677 discloses a technique of applying a bactericide around the air passage in the electric vacuum cleaner body.

However, the problem to be solved by the technique described in the publication is to remove bacteria in the air stream discharged from the cleaner body.

However, the above-mentioned Japanese Patent Laid-Open No. 50-1286.
According to the technique described in Japanese Patent Publication No. 77, the disinfectant applied to the vicinity of the air passage in the cleaner body may come in contact with dust that has been sucked into the cleaner body at high speed, particularly hard dust, and peel it off. It is considered to be sufficient, and if this is repeated over a long period of time, it cannot be denied that the effect of removing germs in the exhaust gas flow by the disinfectant, that is, the disinfectant applied around the air passage in the cleaner body is impaired.

On the other hand, when the bactericide applied around the air passage in the cleaner body is peeled off, or periodically,
It is conceivable to reapply the germicide around the air passage, but it is difficult for a general user to apply the germicide to a narrow space such as the air passage inside the cleaner body,
On the other hand, it is troublesome to entrust this work to a contractor each time, and it is difficult to say that this is a practical method.

On the other hand, when using the electric vacuum cleaner treated by the insecticidal method described in Japanese Patent Laid-Open No. 50-128677, there are also the following problems.

That is, even when the electric vacuum cleaner disclosed in Japanese Patent Laid-Open No. 50-128677 is used, when the dust collecting portion is full of dust, the dust is taken out from the cleaner body. However, since the garbage discarded as described above does not have a barrier object (for example, the wall of a paper bag) around it, pests such as mites that survive in the garbage can easily get around. There is a problem of crawling out. In other words, in the prior art disclosed in Japanese Patent Laid-Open No. 50-128677, the environment which is a countermeasure against harmful insects after the dust filled in the cleaner body is taken out from the cleaner body and discarded We are not aware of hygiene protection, and there is room for improvement in this respect.

On the other hand, according to the present invention, the reproduction of harmful microorganisms such as house mites and mosquito mites once collected on the bag-shaped dust collecting filter by the operation of the vacuum cleaner is greatly suppressed, Furthermore, even if there are mites that escape from the dust collection filter, they can be killed in a short time, and recontamination of living environment with microorganisms can be prevented.

In the above examples, the case where the insect repellent and the acaricide were used was exemplified, but a microbial insecticide having an effect equivalent to this can be used.

[0051]

As explained above, according to the present invention,
Make sure to apply a chemical treatment to the dust discharge prevention lid that closes the strike inlet.
Since the effect of the drug is long-lasting, ticks and fungi
Can be prevented from breeding and garbage can be discarded.
From the dust suction port, harmful microorganisms such as dust and mites
It is possible to prevent spillage.

Further in accordance with the present invention, a disposable fill
By exchanging the tar, the effect of the drug can always be revived
It is possible to replace the disposable filter in this way.
The clue prevents recontamination of living environment with mites and fungi.
It is also excellent in environmental hygiene, and it is easy to use and economical.
Can also provide an excellent vacuum cleaner dust collection filter
it can.
