Description

[0001]
[Industrial application fields]
The present invention relates to a floor suction tool for a vacuum cleaner.
[0002]
[Prior art]
Below, the floor suction tool of the conventional vacuum cleaner is demonstrated, referring a figure.
[0003]
As shown in FIG. 5 and FIG. 6, a brush body 25 is provided in front of and behind the air inlet 26 at the bottom of the suction tool main body 20 constituted by the upper floor nozzle 21, the lower floor nozzle 22, the bumper 23 and the floor nozzle pipe 24. It was a thing.
[0004]
Further, the brush body 25 was a brush 27 that was crimped with a metal plate 28 and mounted on the suction tool body 20.
[0005]
[Problems to be solved by the invention]
However, in the above configuration, since the brush 27 has low airtightness, when the bottom portion of the floor suction tool body 20 is grounded to the floor surface, the degree of vacuum around the air inlet 26 is equivalent to the amount of air sucked through the gap between the brushes 27. And the intake air amount from the left and right ends of the intake port 26 also decreases. Therefore, the dust collecting power at the left and right ends of the suction tool main body 20 is reduced, the suction width that can be collected at one time is reduced, and the deep dust collection efficiency required for sucking in dust that has entered the groove is also improved. It was something that would reduce it.
[0006]
As means for preventing a decrease in the degree of vacuum and a decrease in the intake amount from the left and right ends of the intake port 26, it is conceivable to shorten the length of the brush 27 or change the brush 27 itself to a rubber lip. In order to maintain the operability and the feeling given to the user, at the same time, it is necessary to have a sufficient brush length in consideration of the deflection of the brush 27 so that the bottom surface of the suction tool body 20 does not hit the floor surface. It was difficult to shorten the brush length so that the rigidity was increased more than necessary.
[0007]
In the latter case, the front and rear of the air inlet 26 are completely sealed, the degree of vacuum around the air inlet 26 is increased, and the amount of intake air from both the left and right sides is increased. The force was increased, the operating resistance was remarkably increased, and the user's cleaning effort was increased.
[0008]
The present invention solves these problems, and in a low-cost floor suction tool that does not use a rotating brush or the like, it prevents deterioration of operability and scratches on the floor surface, and improves the suction width and the deep suction performance. An object of the present invention is to provide a floor vacuum cleaner for a vacuum cleaner that reduces the user's cleaning effort.
[0009]
[Means for Solving the Problems]
In order to achieve this object, the first means of the present invention is provided with a brush body configured to sandwich the brush from the front and back with an air-impermeable sheet before and after the intake port formed in the bottom of the suction tool body, The brush body has the length of the air-impermeable sheet sandwiched between the brushes and the air inlet side is almost the same height as the brush, the opposite side is shorter than the brush , and the air-impermeable sheet on the air inlet side is the brush. It is characterized by bending according to the pressure difference between the opposite side .
[0010]
[Action]
In the first means of the present invention, the air tightness of the brush body can be improved without substantially increasing the rigidity of the brush body by sandwiching the brush from the front and back with an air-impermeable sheet. This improves the degree of vacuum around the air intake and at the same time increases the amount of air intake from both the left and right sides of the air intake, so that the suction width can be collected by the suction tool body running on the floor. Can be expanded. Further, the improvement in the degree of vacuum has the effect of improving the sucking up of dust accumulated in the groove portion, can improve the deep dust collection performance, and can reduce the user's cleaning effort.
[0011]
Also, the high substantially the same as the brush an inlet side across the brush Satoshi, with shorter than the brush opposite to the pressure difference between the opposite side impervious sheet of the air inlet side across the brush By being characterized in that it bends accordingly, the air can be sucked in from the tip of the brush body on the opposite side of the air intake port with the brush interposed therebetween. At this time, when the air -impermeable sheet facing the air intake side contacts the floor, the degree of vacuum around the air intake port increases excessively, but the air -impermeable sheet facing the air intake side removes the brush. By bending according to the pressure difference with the opposite side, complete sealing can be prevented and excessive increase in the degree of vacuum around the intake port can be suppressed. As described above, the operation resistance can be adjusted to an appropriate value by bending the air-impermeable sheet according to the degree of vacuum around the air inlet.
[0012]
【Example】
(Example 1)
An embodiment of the present invention will be described below with reference to the drawings. As shown in FIGS. 1 to 3, the suction tool main body 1 includes a floor nozzle 2, a floor nozzle 3, a bumper 4, and a floor nozzle pipe 5, and the floor nozzle pipe 5 is connected to the floor nozzle 2 by a ring 6. And has a retaining structure. Further, brush bodies 8a and 8b disposed before and after the air inlet 7 provided at the bottom of the suction tool body 1 are configured to sandwich the brush 10 from the front and back with a sheet 9 of an air-impermeable material such as resin or rubber. is there.
[0013]
In the present embodiment, the brush body 10 is folded in two on the wire 11, the sheet 9 is folded in two from above, and the metal body 12 is caulked with the brush body 8 a and 8 b. In addition, it is good also as a structure which sandwiches the brush 10 from the front and back with the air-impermeable sheet 9 using another manufacturing means.
[0014]
Further, the length of the air-impermeable sheet 9 is set to be substantially the same as that of the brush 10 on the side of the air inlet 7 with the brush 10 interposed therebetween, and shorter than that of the brush 10 on the opposite side.
[0015]
As described above, by sandwiching the brush 10 from the front and back with the air-impermeable sheet 9, the airtightness of the brush bodies 8a and 8b can be improved without substantially increasing the rigidity of the brush bodies 8a and 8b. As a result, the degree of vacuum around the intake port 7 can be improved, and at the same time, the amount of intake air from the left and right ends of the intake port 7 can be increased. As a result, the suction tool body 1 travels on the floor surface, thereby collecting dust. It becomes possible to widen the suction width. Further, the improvement in the degree of vacuum has the effect of improving the sucking up of the dust accumulated in the groove, and the deep part dust collecting performance can be improved. Thereby, a user's cleaning effort can be reduced.
[0016]
Moreover, in the air-impermeable sheet 9 of the brush bodies 8a and 8b, the brush 10 is sandwiched between the brush 10 and the air inlet 7 side is almost the same height as the brush 10 and the opposite side is shorter than the brush 10, so that the brush 10 is first removed. Thus, intake from the tip of the brush bodies 8a, 8b on the opposite side to the intake port 7 can be performed. At this time, when the air-impermeable sheet 9 facing the air inlet 7 is in contact with the floor, the degree of vacuum around the air inlet 7 is excessively increased, but the air-impermeable sheet 9 facing the air inlet 7 is excessively increased. However, by bending as shown by the dotted line in FIG. 3 according to the pressure difference between the opposite side across the brush 10, the complete sealing is prevented and the vacuum degree around the inlet 7 is prevented from excessively rising. It is something that can be done. As described above, the operation resistance can be adjusted to an appropriate value by bending the air-impermeable sheet 9 in accordance with the degree of vacuum around the air inlet 7. Thereby, the excessive effort which a user requires for operation can be suppressed.
[0017]
(Example 2)
The second embodiment of the present invention will be described below.
[0018]
As shown in FIG. 4, the feature of this embodiment is that the configuration of the first embodiment is replaced with the brush bodies 8a and 8b, and the sheet 9 covers the entire circumference of the brush 10 and is shorter than the brush 10. That is, the brush body 8c is arranged in front of and behind the air inlet 7.
[0019]
According to this configuration, in addition to the same effects as those of the first embodiment, it is possible to prevent the squeezing caused by the falling of the brush 10, and to reduce the return loss due to the falling of the hair that occurs during distribution.
[0020]
【The invention's effect】
As described above, according to the present invention, in the first means, the air tightness of the brush body can be improved without substantially increasing the rigidity of the brush body by sandwiching the brush from the front and back with an air-impermeable sheet. it can. This improves the degree of vacuum around the air intake and at the same time increases the amount of air intake from both the left and right sides of the air intake, so that the suction width can be collected by the suction tool body running on the floor. Can be expanded. Further, the improvement in the degree of vacuum has the effect of improving the sucking up of the dust accumulated in the groove part, and the deep part dust collecting performance can be improved, whereby the user's cleaning effort can be reduced.
[0021]
Also, in the impervious sheet of the brush body, substantially flush Satoshi the brush an inlet side across the brush, by the opposite shorter than the brush, firstly the air inlet across the brush opposite The air can be sucked from the tip of the brush body. At this time, when the air -impermeable sheet facing the air intake side contacts the floor, the degree of vacuum around the air intake port increases excessively, but the air -impermeable sheet facing the air intake side removes the brush. By bending according to the pressure difference with the opposite side, complete sealing can be prevented and excessive increase in the degree of vacuum around the intake port can be suppressed. As described above, the operation resistance can be adjusted to an appropriate value by bending the air-impermeable sheet according to the degree of vacuum around the air inlet.
