Can be attached. Further, as the charcoal 4A, Bincho charcoal (white charcoal), activated carbon, bamboo charcoal, charcoal (black charcoal) or the like can be adopted, and the odor components in the dust collection chamber 22 can be effectively adsorbed and removed by the charcoal 4A.

  As shown in FIG. 2, the bag body 2 includes a thin inner layer paper 6, an intermediate layer material 7 disposed outside the inner layer paper 6, and an outer layer paper 8 disposed further outside the intermediate layer material 7. It is composed of Further, the inner layer paper 6 and the outer layer paper 8 are made using pulp materials and synthetic fibers such as polyester fibers, PVA fibers, acrylic fibers and the like as raw materials. In the present embodiment, the thickness of the outer layer paper 8 is formed thinner than the conventional one.

  Furthermore, the intermediate layer material 7 is formed of an electret (melt blow) nonwoven fabric. This electret (electric stone processing) non-woven fabric always retains electric polarization in each fiber, so that fine particles containing odorous components, germs, pollen, etc. are reliably adsorbed by the electric dust collecting action. Can be removed. Further, the paper layer (mesh) of the intermediate layer material 7 is formed to be coarser than that of the outer layer paper 8. Furthermore, dust of a predetermined size or more sucked into the dust bag 1 is captured when passing through the inner layer paper 6, but fine dust passes through the inner layer material 7 after passing through the inner layer paper 6.

It is preferable to use Bincho charcoal obtained by processing the above into an ultrafine powder of 15 μm or less. The deodorizing effect can be further enhanced by disposing a platinum catalyst having a deodorizing action in the dust collection chamber.

  The inner layer paper 6 contains an allergen inactivating agent 11 and an antibacterial agent 12. Examples of the allergen inactivating agent 11 include polyphenols such as tannic acid and gallotannin, hydroxybenzoic acid compounds such as 2,5-dihydroxybenzoic acid, organophosphorus compounds, and pyrethroid compounds. As the antibacterial agent 12, p-chloromethazole, o-phenylphenol, or the like can be used.

  In the dust bag 1 having the above-described configuration, dust of a predetermined size or more sucked into the bag body 2 is captured when passing through the inner layer paper 6, but fine dust passes through the inner layer paper 6 and then passes through the intermediate layer. Almost all of the fine particles such as odor components pass through the intermediate layer material 7 when they pass through the material 7.

  According to the present embodiment, the bag body 2 is formed of a three-layer structure of an inner layer paper 6, an intermediate layer material 7, and an outer layer paper 8, and the inner layer paper 6 and the outer layer paper 8 have a high adsorption action such as Bincho charcoal. Since the powdered charcoal 9 and 10 are blended, the odorous substance (including toxic gas) sucked into the bag body 2 passes through the inner layer paper 6 and the outer layer paper 8, and the powdered charcoal 9 , 10 for reliable adsorption removal. In this case, the odorous substance is adsorbed and removed by the charcoal 9, 10 regardless of whether it is acidic, basic or neutral.

  By the way, according to the conventional product, the dust sucked by the electric vacuum cleaner generates a bad odor in the dust collecting chamber, and in particular, when the electric vacuum cleaner is not used, a part of the dust is fermented to generate a bad odor component, The bad odor was dissipated to the outside of the dust collection chamber when the electric vacuum cleaner was used, causing discomfort to the user. In this respect, the present invention strongly adsorbs and deodorizes the malodorous component in the bag body 2 regardless of whether the electric vacuum cleaner is used or not, so there is no possibility of giving the user unpleasant feeling.

  According to the actual deodorization experiment, the malodorous component sucked by the electric vacuum cleaner could be almost removed by the deodorizing action by the granular charcoal 9 and 10. In tests based on the 6-step odor intensity method, the odor intensity of ammonia (pet odor), acetaldehyde (bacterial odor), methyl disulfide, isovaleric acid, etc., which are representative components of garbage odor, is 1 or less, that is, human However, it was possible to suppress the odor level almost undetectable.

As described above, when the odorous substance passes through the inner layer paper 6 or the outer layer paper 8 and is adsorbed and removed by the granular charcoal 9 and 10, a high deodorizing function is added to the dust bag 1 itself. Further, since it is not necessary to form the outer layer paper 8 thick, the air permeability and flexibility of the outer layer paper 8 are maintained. As a result, the attachment property of the dust bag 1 to the vacuum cleaner and the suction dust collection property were ensured, and the dust collection efficiency was improved by 1.5 times or more compared to the conventional case. The charcoal 9 and 10 are natural materials, and since thinned wood can be effectively used as charcoal, it can contribute greatly to the conservation of the forest environment that is kind to the earth.

  Furthermore, since the allergen deactivator 11 is blended in the inner layer paper 6, allergen substances such as mites and pollen in the dust are effectively used by the allergen deactivator 11 when passing through the inner layer paper 6. Inactivated.

  In this case, a part of the allergen substance having a fine particle diameter passes through the outer layer paper 8 and leaks from the dust bag 1, but the activity of the allergen substance has disappeared (or attenuated). Contact with the substance did not cause allergic diseases. Furthermore, since various germs receive an antibacterial action due to the antibacterial agent 12 blended in the inner layer paper 6, the user's health was not harmed by the germs.

In addition, since the intermediate layer material 7 is formed of an electret nonwoven fabric having a high dust collection performance, fine dust that has passed through the inner layer material 6 and fine particles such as odor components, germs, and house dust (for example, a particle size of 0.5 μm or less). ) Fine particles could be effectively adsorbed and trapped by the intermediate layer material 7. Therefore, since high dust collection efficiency can be obtained without forming the outer layer paper 8 thick, the air permeability and flexibility of the outer layer paper 8 can be maintained well.

  FIG. 4 to FIG. 6 are detailed sectional views showing other embodiments of the present invention, respectively, which are characterized by both the intermediate layer material 7 and the outer layer paper 8 (FIG. 4) in addition to the configuration of FIG. Or allergen deactivators 13 and 14 and antibacterial agents 15 and 16 are contained (mixed or applied) in one (configuration of FIG. 5 or FIG. 6). The other configuration is the same as that of FIG.

  Thus, if the allergen inactivating agent 13 or 14 and the antibacterial agent 15 or 16 are contained in the intermediate layer material 7 or the outer layer paper 8, the allergen substance and the germs are not only when passing through the inner layer paper 6, but also in the middle. Even when passing through the layer material 7 or the outer layer paper 8, the allergen inactivating action by the allergen inactivating agents 13 and 14 and the antibacterial action by the antibacterial agents 15 and 16 are exhibited. Function is further increased.

  In the above embodiment, the powdered charcoal 9 and 10 is contained in the inner layer paper 6 and the outer layer paper 8, but the charcoal 9 and 10 can also be contained in the intermediate layer material 7. When the inner layer paper 6, the intermediate layer material 7 and the outer layer paper 8 contain charcoal 9 and 10, the odorous substance is adsorbed in three stages when passing through the inner layer paper 6, the intermediate layer material 7 and the outer layer paper 8. Since it is removed, the deodorizing effect is further increased.

  It should be noted that the present invention can be variously modified without departing from the spirit of the present invention, and the present invention naturally extends to the modified ones.
