Abstract

(57) [Summary] [Purpose] The purpose of the present invention is to prevent the user from lowering the operability and scratching the floor surface, and at the same time, to improve the suction width and the deep suction performance to reduce the cleaning labor of the user. [Composition] At least one of the front and rear of an intake port 7 provided on the bottom surface of the suction tool body 1 is provided with a brush body 8 in which a gas impermeable sheet 9 is sandwiched in a brush 10. The length of the brush is shorter than the length of the brush 10, and a ventilation passage is provided at the tip of the brush.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a floor suction tool for an electric vacuum cleaner.

[0002]

2. Description of the Related Art Heretofore, a floor suction device of this type has generally been constructed as shown in FIGS. The configuration will be described below with reference to the drawings.

In FIG. 5, 20 is a Yuka nozzle wafer 2.
1, a Yuka nozzle shatter 22, a bumper 23, and a Yuka nozzle pipe 24, which is a suction tool body, and a brush body 25 is provided at the bottom of the suction tool body before and after the intake port 26.

Further, the brush body 25 is one in which the brush 27 is crimped with a metal plate 28 and is attached to the suction tool body 20.

As a result, the suction tool body 1 is moved back and forth while the brush 27 is flexed to collect dust on the floor.

[0006]

However, in the above construction method, since the brush is low in airtightness, when the floor bottom suction tool body bottom is grounded to the floor surface, the amount of air taken in through the gap between the brushes The degree of vacuum around the mouth decreases, and the amount of intake air from the left and right ends of the intake port also decreases. Therefore, the dust collection power at both left and right ends of the suction tool is reduced, the suction width that can collect dust at one time is reduced, and the deep dust collection efficiency required to suck the dust that has entered the groove etc. is also reduced. It was something that ended up.

As a means for preventing a decrease in the degree of vacuum and a decrease in the amount of intake air from the left and right ends of the intake port, it is conceivable to shorten the length of the brush or change the brush itself to a rubber lip. It is necessary to have sufficient brush length in consideration of the bending of the brush so that the bottom surface of the tool body does not damage the floor surface, and at the same time, the rigidity of the brush is more than necessary to maintain the operability and the feel given to the user. It was difficult to shorten the brush length so that

In the latter case, before and after the intake port is completely sealed, the degree of vacuum around the intake port is increased, and the amount of intake air from both left and right ends is increased. Is increased, which significantly increases the operation resistance and increases the cleaning effort of the user.

The present invention solves these problems, and in a low-cost floor suction tool that does not use a rotating brush or the like, prevents deterioration of operability and damage to the floor surface, and at the same time improves suction width and deep suction performance. By improving the above, the cleaning labor of the user is reduced.

[0010]

In order to achieve the above object, the first means of the present invention is to provide a suction port provided at the bottom of a suction tool body, which is composed of a Yuka nozzle, a Yuka nozzle, and a Yuka nozzle pipe. A brush body is provided at the front and rear, and at least one of the brush bodies is formed by sandwiching an impermeable sheet between the brushes.

As a second means, the air-impermeable sheet of the brush body has a length shorter than the brush length to form an air passage at the tip of the brush.

[0012]

In the first means of the present invention described above, by sandwiching the impermeable sheet between the brushes, the airtightness of the brush body can be improved with almost no increase in the rigidity of the brush body. As a result, the degree of vacuum around the intake port can be improved and at the same time the amount of intake air from the left and right ends of the intake port can be increased. Further, it can be said that the improvement of the degree of vacuum has the effect of improving the suction of dust accumulated in the groove portion, and can improve the deep portion dust collecting performance.

As a result, the cleaning labor of the user can be reduced. In the second means,
By making the impermeable sheet shorter than the brush, it is possible to inhale air from the tip of the brush. As a result, it is possible to prevent the operating resistance from increasing by preventing the complete sealing by the brush bodies provided before and after the intake port and suppressing the excessive increase in the vacuum degree around the intake port. As a result, it is possible to suppress the excessive labor required by the user for the operation.

[0014]

Embodiments will be described below with reference to the accompanying drawings. 1 to 3, reference numeral 1 denotes a main body of a suction tool including a Yuka nozzle upper 2, a Yuka nozzle lower 3, a bumper 4, and a Yuka nozzle pipe 5. The Yuka nozzle pipe 5 is connected to the Yuka nozzle upper 2 by a ring 6 to prevent slipping off. Has become. Further, a brush body 8 is provided in front of and behind the intake port 7 provided at the bottom of the suction tool body 1. The brush body 8 has an impermeable sheet 9 (resin film, rubber sheet, etc.).
There is something in between. In this embodiment, the wire rod 11
Fold the impermeable sheet 9 in two and brush 10 from above
The brush body 8 is configured by folding the sheet in two and covering it with the metal plate 12 and the same effect can be obtained by sandwiching the impermeable sheet 9 between the brushes 10 by other manufacturing means. Is what you get.

The impermeable sheet 9 is shorter than the brush 10. As described above, first, the air-impermeable sheet 9 is sandwiched between the brushes 10, whereby the airtightness of the brush body 8 can be improved with almost no increase in the rigidity of the brush body 8. 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.
By running the suction tool body 1 on the floor surface, it is possible to widen the suction width in which dust can be collected. Further, it can be said that the improvement of the degree of vacuum has an effect of improving the suction of dust accumulated in the groove and can improve the deep-part dust collecting performance. As a result, it is possible to reduce the cleaning labor of the user.

By making the impermeable sheet 9 shorter than the brush 10, it is possible to inhale air from the tip portion of the brush 10. This allows the intake port 7
It is possible to suppress an increase in operation resistance by preventing the complete sealing by the brush bodies 8 provided before and after and suppressing the excessive increase in the vacuum degree around the intake port 7. As a result, it is possible to suppress the excessive labor required by the user for the operation.

[0017]

As described above, according to the present invention, in the first means, by sandwiching the impermeable sheet between the brushes, the rigidity of the brush body is hardly increased and the airtightness of the brush body is improved. You can improve. As a result, the degree of vacuum around the intake port can be improved and at the same time the amount of intake air from the left and right ends of the intake port can be increased. Can be expanded. Further, it can be said that the improvement of the degree of vacuum has an effect of improving the suction of dust accumulated in the groove and can improve the deep-part dust collecting performance. As a result, it is possible to reduce the cleaning labor of the user.

In the second means, the air-impermeable sheet is made shorter than the brush so that air can be taken in from the tip of the brush. This prevents complete sealing by the brushes installed before and after the intake port,
By suppressing an excessive increase in the degree of vacuum around the intake port, it is possible to suppress an increase in operating resistance. As a result, it is possible to suppress the excessive labor required by the user for the operation.
