DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a dust-collecting bag for an electric vacuum cleaner, which is formed by laminating a paper core and a paper core.

[0002]

2. Description of the Related Art As shown in FIG. 6, a conventional dust-collecting bag of a vacuum cleaner is provided with air inlets 3 in both a core 1 made of a hard mount and a paper bag 2, and these portions are joined together and adhered. ing. Further, the mouth 1 is provided with an L-shaped flange portion 5. The dimension of the collar portion 5 is L2> L at the perforation 4 shown in FIG.
1, RI> R2, and when turned back at the perforation 4, as shown in FIG. Therefore, when the dust collection bag is full of dust and the dust is to be discarded, the dust is taken out of the cleaner body (not shown) and covered with the collar 5 as shown in FIG. 7 to prevent dust spilling and scattering. And can be sanitarily dumped. Furthermore, an L-shaped flange 5 provided on the mouth 3
Is formed to be easy to carry.

[0003]

However, in the structure of such a conventional dust bag, as shown in FIG. 6, the dimension L2 of the mouth core 3 needs to be formed larger than the minimum required dimension L1. It is necessary to increase the size of the core 3, and not only the cost but also the width of the dust collecting chamber of the cleaner must be increased, which limits the reduction in size and weight of the cleaner.

An object of the present invention is to solve the above-mentioned problem, and an object of the present invention is to provide a dust collecting bag of a vacuum cleaner which is small and has a dust spill prevention function.

[0005]

SUMMARY OF THE INVENTION In order to achieve the above-mentioned object, the present invention provides an air inlet provided on a substantially square plate of rigid backing paper, and an air inlet which is aligned with the air inlet. In a dust collecting bag of a vacuum cleaner comprising a paper bag adhered along a mouth, a slit is provided in the mouth core along an outer periphery of an adhesive portion, and perforations are extended in opposite directions from both ends of the slit. This perforation is arranged such that when the outer core of the slit is folded with reference to the perforation, the outer peripheral end of the folded portion of the core is longer than the farthest end of the intake port. It is configured as follows.

[0006]

According to the present invention, the intake port can be closed at the folded portion of the center by folding the outside center of the slit based on the perforation by the above configuration, and the folded portion of the center has a substantially square shape. The corner can be downsized by adopting the corner portion.

[0007]

An embodiment of the present invention will be described below with reference to the accompanying drawings. In FIG. 3, reference numeral 6 denotes a main case,
A dust suction chamber 8 having an upward opening 7 is provided at the front inside, and a main chamber 11 having a built-in electric blower 10 separated by a partition 9 at the rear, and a handle 12 for carrying is formed at the forefront. are doing. Reference numeral 13 denotes a pair of large wheels for movement attached to the main case 6, and reference numeral 14 denotes a free wheel attached to the bottom surface of the main case 6. The upper opening of the electric blower 10 is covered with an upper lid 15, and the upper lid 15 and the main case 6 are fixed with screws (not shown). Reference numeral 16 denotes a front cover provided in front of the main case 6, above which the main case 6 is mounted.
Has a bumper 17 made of vinyl chloride mounted on the outer periphery of the bumper. A suction port 19 is provided substantially at the center of the front wall 18 of the dust suction chamber 8.
And a check valve 20 made of natural rubber is attached to the suction port 19 and fixed to the front wall 18 with screws. Reference numeral 21 denotes a case connection port formed in the front cover 16. When the front cover 16 is fixed to the front wall 18, the hose connection port 21 and the check valve 20 are coaxial. Numeral 22 denotes a dust collecting bag serving as a filter for capturing dust. As shown in FIGS. 1 and 2, the dust collecting bag 22 is formed in a substantially square plate made of a thick board such as cardboard as shown in FIG. Core 24 having an intake port 23 of
3 and a paper bag 26 whose mouth is adhered to and adhered via an adhesive portion 25. Two slits (cutout holes) 29 having a connecting portion 28 on a diagonal 27 along the outer periphery of the bonding portion 25 are formed in the core 24. Slit 2
A perforation 30 extending in a direction substantially perpendicular to the diagonal line 27 and in a direction opposite to each other is provided at the end portion 29 a of the line 9. Here, the perforations 30 are such that the outer peripheral end of the core 24 is longer than the farthest end 23a of the intake port 23 when the corner 24a of the core 24 is turned back with reference to the perforations 30 as shown in FIG.
Is set at a position where dimension L> L ′.

In the above configuration, when cleaning is performed,
The mouth core 24 of the dust bag 22 is set in the suction port 19 in a flat state as shown in FIG. When the dust collection bag 22 is full and dust is to be discarded, the connecting portion 28 of the mouth 24 of the dust collection bag 22 is cut off, and the corner portion 24 is determined based on the perforation 30.
a, the corner portion 2 as shown in FIG.
Most of the intake port 23 can be closed by 4a, and the dust can be prevented from spilling during the dusting movement. Further, by providing the connecting portion 28 with a plurality of slits 29, the strength of the flat core 24 is improved, and the setting of the suction port 19 is ensured.

Further, as shown in FIGS.
9 forms a substantially U-shaped protruding portion 29b toward the corner at a portion crossing the diagonal line 27 of the mouth core 24, so that the corner portion 24a is folded back and the dust collection bag 22 is moved as described above. And the usability is improved.

As described above, the intake port 23 can be closed by the corner portion 24a of the core without increasing the size of the core 24 as in the prior art, and the core 24 can be significantly reduced in size.

[0011]

As is apparent from the above description, according to the present invention, a lid and a perforation are formed on the mouth of the dust collecting bag when the dust collecting bag is discarded, and the portion is folded back. , The size of the mouth can be reduced,
As a result, the size of the dust bag can be reduced.
As a result, the design limitation resulting from the dust bag is largely eliminated, and a small and lightweight vacuum cleaner can be provided.
