Abstract

PURPOSE:To achieve a prevention of erroneous mounting of a bag support on a cut groove along with a higher strength of a mouth core by connecting the mouth core to a part of one cut groove of a cover lid body. CONSTITUTION:A mouth core 25 and a lid body 26 of a dust suction port 28 are made up of one sheet of hard paper in a dust collection filter. A cut groove 31 extending to the side 28 of the dust suction port is connected to the final end of a positioning groove 32 between the mouth core 25 and the cover lid body 26 to prevent erroneous mounting of the mouth core 25 of a dust collection filter and the lid body 26 on the end of a bag support 33 while achieving a higher strength and a prevention of deformation. The lid body 26 is engaged with the dust suction port 28 thereby enabling the closing of the dust collection port 28 accurately.

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a dust collecting filter for an electric vacuum cleaner.

[0002]

2. Description of the Related Art Conventionally, a dust collecting filter of this type has a structure in which dust is collected by a dust collecting filter as described in Japanese Patent Application No. 61-67455 and Japanese Patent Publication No. 3-10326. Having a lid body for closing a dust suction port of the core, the core and the cover being formed from a single piece of hard paper, and two cut grooves being provided between the core and the cover Things are known. This will be described below with reference to FIGS. In this type of vacuum cleaner, the dust collection chamber 6 is arranged in the front and the electric blower 2 is arranged in the rear,
A dust collecting filter is provided in the dust collecting chamber 6 via a bag support 11.
9 is detachably attached. The dust collection filter-9 is
It is attached to the bag support 11. Further, in general, after dust is collected by the dust collecting filter-9, the dust is not scattered from the dust suction port 20 to the outside as described in JP-B-3-10326. After the dust is collected in 9, the two cut grooves 18a and 18b are provided between the mouth core 10 and the lid body 19 so as to close the dust suction port 20 of the mouth core 10, and the lid is bent to make a lid. It has been known.

Reference numeral 1 denotes a main body having a built-in electric blower 2, which comprises an upper member 4 and a lower member 3, and a bumper 5 is held between these members. The dust collection chamber 6 formed on the suction side of the electric blower 2 is opened and closed by the dust collection chamber lid 7. The dust collection chamber cover 7 is attached to the upper member 4 so as to be rotatable around a support shaft 8. The dust collecting filter 9 is attached to the bag indicator 11 in which the mouth core 10 is rotatable in the direction of the opening 12 of the dust collecting chamber 6.
Usually, the upper surface 13 of the core 10 of the bag support 11 and the core contact surface 1
6 is urged by the elastic member 15 so as to be flush with the surface. The core contact surface 16 is an intake port provided in the dust collection chamber cover 7, and the core core 10 is biased toward the intake port 16 contact surface side by the bag support 11.

As shown in FIGS. 5 and 6, a dust collecting filter
9 includes a bag-shaped body 22, a mouth core 10, and a lid body 19. The core 10 has a dust suction port 20 and a lid 19. The core 10 and the covering lid 19 are provided with two cut grooves 18a, 18b extending between them toward the dust suction port 20 side of the core 10, Since only the folding line 21 is connected between the vicinity of the tips of the two cut grooves 18a and 18b, the lid 1
9 is bent and press-fitted to the dust suction port 28 of the core 10, so that the dust suction port 20 can be closed.

[0005]

In such a conventional structure, the lid 19 has two cut grooves 18a and 18b for facilitating the bendability thereof.
When the dust collecting filter 9 is mounted on the bag support 11 by 18b, the bag support 11 may be accidentally inserted into the cut groove 18a and mounted. Therefore, there is a problem in that the mouth core 10 is inclined and a gap is generated at the joint with the intake port 16 so that the dust does not enter the dust collecting filter and the dust leaks into the dust collecting chamber 6 of the electric vacuum cleaner. Was there.

SUMMARY OF THE INVENTION It is an object of the present invention to provide a dust collecting filter for an electric vacuum cleaner having a structure capable of preventing the dust collector from being erroneously mounted and easily closing the dust suction port of the core. Is.

[0007]

The present invention for solving the above-mentioned problems comprises a mouth core and a covering lid which is connected to one side of the mouth core and which covers the dust suction port. In a dust collecting filter for an electric vacuum cleaner, wherein the cover lid and the core are formed from a single piece of hard paper, the cover lid has a notch groove extending toward the dust inlet between the cover lid and the cover. Is provided to connect with the bending line portion provided near the tip of the cutting groove, and the closing lid and the core can be separated from the cutting groove at the tip in the insertion direction near the end. And a connecting portion connected to.

[0008]

According to the present invention having the above-mentioned structure, when the dust collecting filter is attached to the bag support by connecting the notch provided in the mouth core, it is erroneously attached when the bag support enters the cut groove. Can be prevented. The strength of the core is further improved by connecting the end portions of the cut grooves.

[0009]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below with reference to the accompanying drawings.

As shown in FIGS. 1 to 3, a dust collecting filter
35 includes a bag-shaped body 24 and a core 25. Bag 24
Is formed of a filter material such as a flexible filter paper having air permeability. The core 25 is made of hard paper. The mouth core 25 and the bag-shaped body 25 are bonded by an adhesive. The mouth core 25 has a dust suction port 28 and a closing lid body 26. The mouth core 25 and the cover lid 26 are arranged between the mouth core 25 and the cover lid 26.
A connecting portion 29 is provided in the vicinity of the end of the cut groove 32 on the tip side in the insertion direction of the mouth core 25 having two cut grooves 31 extending toward the dust suction port 28 side and a positioning groove 32. A cut line 30 is provided in a part of the connecting portion 29. Notch groove 31
A fold line portion 27 is provided near the tip of the positioning groove 32 to connect the lid body 26 and the core 25.

Further, the cut line 31 is a bag support 33.
Positioning is performed in association with the projection 36 provided on the.

In the above structure, when the dust collecting filter 35 is mounted on the bag support 33, the bag support 33 is inserted between the core 25 and the bag-shaped body 24 and mounted. The cut groove 32 is the lid 2
Since the bag support 33 is not connected to the cut groove 32, the cut groove 32 can be aligned with the convex portion 36 of the bag support 33 for positioning.

At the time of dumping dust, the dust collection chamber lid 7 is opened, and the core 25 of the dust collection filter 35 in the dust collection chamber 34 is pulled out from the bag support 33 to remove the dust collection filter 35.

Then, the lid 26 is bent along the score line 27 toward the dust inlet 28 side so that dust inside the dust collecting filter-35 does not scatter. At that time, the connecting portion 29 is separated by the cut line 30 provided in the vicinity of the connecting portion 29, and the lid 26 is easily bent.

Further, the dust suction port 28 is connected to the lid 26 so that the dust suction port 28 can be securely closed, and no dust leaks from the dust suction port 28.

[0016]

As described above, according to the present invention, the bag supporting member is mounted when the dust collecting filter is attached by connecting the lid for closing the dust suction port of the core and a part of the cut groove of the core. It is possible to prevent erroneous attachment to the end of the body, ensure good positioning, prevent dust from leaking into the dust collection chamber, and completely collect it in the dust collection filter. Further, by connecting a part of the cut grooves, the strength of the core is improved and the leakage of dust due to deformation such as warpage can be prevented.
