Description

[Detailed description of the device]

[0001]

[Technical field to which the device belongs]

 The present invention relates to a dust collecting filter for an electric vacuum cleaner, and more particularly, when air containing dust is inhaled, it is easy to open, and the air pressure effectively prevents peeling of the body sticking part of the bag body. The present invention relates to a dust collecting filter for an electric vacuum cleaner.

[0002]

[Prior art]

 Conventionally, disposable dust filters used in vacuum cleaners have a suction port provided on one wall of a horizontally long cylindrical body with a breathable material attached to the body, with the stacking margin removed and the suction port provided on both sides. On the suction port of the bag body with the open end closed, a support plate having an opening having substantially the same size as or larger than that of the suction port is attached, and the bag body including the both-side closed ends is attached. Most of both sides are folded on the back side of the support plate so that both sides fold on top of each other.

[0003]

[Problems to be solved by the device]

 However, when inhaling air containing dust, these dust collecting filters are difficult to open because the folded sides of the bag body are folded on top of each other, so that the air pressure near the suction port, especially on the wall facing the suction port, is reduced. Was sometimes concentrated, and the torso sticking part of such a part was sometimes peeled off. The present invention has been made in view of the above circumstances, and its problem is an electric cleaning that effectively prevents peeling of the body sticking portion of the bag body due to air pressure when sucking air containing dust. It is to provide a dust collecting filter for a machine.

[0004]

[Means for Solving the Problems]

 In order to solve the above-mentioned problems, a dust collecting filter for a vacuum cleaner according to the present invention has a suction port provided on one wall surface of a horizontally long cylindrical body to which one or more layers of breathable material are stuck. On the inlet of the bag whose both open ends are closed, a hard support plate having an opening having substantially the same size as or larger than the inlet is attached, and the both closed ends are support plates. In a dust collecting filter for an electric vacuum cleaner, in which both sides of the bag are folded so as to be positioned on the back side of the bag, the suction port is provided on the stacking area of the body and is folded on the back side of the support plate. It is characterized in that both sides of the bag are not folded over each other.

[0005]

[Embodiment of device]

 In the dust collecting filter of the present invention, since both sides of the bag body folded on the back side of the support side are not folded on top of each other, the air that flows in from the inlet opens smoothly and the empty space near the inlet is excessively large. The pressure is not concentrated and there is no body sticking part in that part, or it is within the sticking area of the support plate and the bag body where the air pressure is the most difficult to apply, so it is said that the peeling of the body sticking part is effectively prevented. The action is achieved.

【Example】

 Hereinafter, an embodiment of the present invention will be described in detail with reference to the drawings, but the present invention is not limited thereto. FIG. 1 is a plan view of a dust collecting filter for an electric vacuum cleaner according to an embodiment of the present invention as viewed from the support plate side, showing a state before folding both side portions of the bag body to the back side of the support plate. FIG. 2 is a plan view of the dust collecting filter shown in FIG. 1 viewed from the back side of the support plate. Fig. 3 is a side end view showing a state in which both sides of the dust collecting filter bag shown in Figs. 1 and 2 are folded to the back side of the support plate, and Fig. 4 shows the dust collecting filter bag of Fig. 1. It is a perspective view of the cylindrical body which comprises.

In the figure, reference numeral 1 is a bag body, 1'is a tubular body constituting the bag body 1, 1a is a suction port of the bag body, 1b and 1c are closed ends of the bag body, 1'b and 1 '. c is the opening end of the tubular body 1 ', 1d is the stacking and stacking margin, 1e is the body glue, 2 is the support plate, 2a is the opening of the support plate, 2b and 2c are non-bonded parts of the support plate, 3 is an adhesive part, 4 is both sides of the bag, and 4a and 4b are folding lines.

In the dust collecting filter of the present embodiment, as shown in FIG. 4, when the inlet 1a is provided on the cylinder-bonding stacking margin 1d on the wall surface of the horizontally long cylindrical body 1'which is cylinder-bonded with one layer of filter paper. Both side open ends 1'b and 1'c of the tubular body are bent twice and adhered together, and as shown in FIG. 2, on the suction port 1a of the bag body 1 having the closed ends 1b and 1c, As shown in FIG. 1, a thick board supporting plate 2 having an opening 2a is adhered 3 so that the closed ends 1b and 1c are located on the back side of the supporting plate 2 along the folding lines 4a and 4b. It is formed by folding both sides 4 of the bag body including the closed ends 1b and 1c. It should be noted that both sides 4 of the bag body folded to the back side of the support plate 2 are not folded over each other as shown in FIG.

In the case of the present embodiment, as shown in FIG. 1, a non-adhesive portion is provided between the support plate and the bag body 1 so that the support plate 2 can be attached to the dust collecting filter attachment portion of the electric vacuum cleaner. 2b and 2c are provided, but depending on the structure of the vacuum cleaner, this non-adhesive part may be provided along the sides of the support plate 2 extending in the left-right direction in FIG. 1 may extend in the vertical direction in FIG. 1 beyond the edge of the bag body 1 and the protruding portion may be set in the electric vacuum cleaner.

When the dust collecting filter of this embodiment is set in an appropriate electric vacuum cleaner and the electric vacuum cleaner is started, it is folded along the folding lines 4a and 4b on the back side of the support plate 2. Since both sides 4 of the bag are not folded on top of each other, the air flowing in through the inlet opens them smoothly so that no excessive air pressure is applied to the body pasting portion 1a. Further, in the dust collecting filter of the present embodiment, as shown in FIG. 5, the suction port 1a is provided so as to partially cover the body-bonding overlapping margin 1d of the cylindrical body 1'constituting the bag body 1. The body glue 1e may be adhered to the inner portion in a continuous line shape over the entire length of the tubular body 1 ', and in this case, the same effect as above can be obtained.

[0011]

[Effect of device]

 In the dust collecting filter of the present invention, since both sides of the bag body folded on the back side of the supporting side are not folded on top of each other, they are smoothly opened by the air flowing in from the intake port and excessively empty near the intake port. If the pressure is not concentrated and there is no torso sticking part in that part, or even if it exists, it is in the sticking area of the support plate and the bag that is most difficult to apply air pressure, so peel off the torso sticking part. It can be effectively prevented. As described above in detail, according to the present invention, when the air containing dust is inhaled, the air pressure is used to effectively prevent the body sticking portion of the bag from being peeled off. A dust collecting filter can be provided.
