Description

[Detailed Description of the Invention] Technical Field of the Invention This invention relates to a suction port body for a vacuum cleaner, which is not used for cleaning tatami mats or carpets, but is used for cleaning walls, furniture, etc.

Technical background of the invention and its problems As shown in Figure 1, the suction port of a vacuum cleaner used for cleaning walls, furniture, etc. is conventionally placed at the rear of the main body 1 at the dust collection part of the vacuum cleaner. A connecting pipe 4 connected via an extension pipe 2 and a suction hose 3 is fixedly provided. However, as shown in FIG. 2, when cleaning by moving the main body 1 from side to side, the main body 1 tilts with respect to the surface to be cleaned 5, resulting in a gap between the surface to be cleaned 5 and the suction port. There is a disadvantage that the suction force decreases due to the increase in the Further, when the main body 1 is moved from side to side, the pressing force against the surface to be cleaned 5 is weak, so there is a drawback that the sweeping action is insufficient despite the presence of the brush bristles 6.

Purpose of the invention This invention was created in view of these points. When cleaning by reciprocating the main body in the left and right direction, it is placed along the surface to be cleaned, and the vertically long rotating brush is rotated to remove dust. The object of the present invention is to obtain a suction port body for a vacuum cleaner that can suction suction well.

Summary of the invention In this invention, a rotary tube connected to the dust collection part of a vacuum cleaner is rotatably attached to the main body, and when the main body is reciprocated from side to side for cleaning, the main body can be cleaned over a wide area. Move parallel to the surface and further rotate the rotating brush to increase the sweeping action,
Therefore, the structure is such that dust can be sucked in well.

Structure of the invention An embodiment of this invention will be described based on FIGS. 3 to 7. A vertically elongated main body 12 is provided, which is a pair of a left case 10 and a right case 11. A vertically elongated suction port 13 is formed in the lower part of the main body 12, and a plurality of bundles of brush bristles 14 are planted at predetermined intervals around the periphery of the suction port 13. Furthermore, the main body 12 is partitioned with a partition wall 15 to provide a turbine chamber 16 and a turbine chamber 1.
A brush chamber 17 located at the lower part of the brush chamber 6 is formed. This brush chamber 17 has a vertically long rotating brush 1.
8 is rotatably held and stored in the partition wall 15, and this rotating brush 18 has the bristles 14
Brush bristles 19 having a length extending downward are spirally implanted. The turbine chamber 16
A turbine 20 is rotatably held and housed in the partition wall 15, and a belt 21 is suspended between the shaft of the turbine 20 and the rotating brush 18. The partition wall 15 is provided with a vent 22 that allows the turbine chamber 16 and the brush chamber 17 to communicate with each other and guides the intake air to the turbine 20.

One end of a rotary tube 23 is attached above the rear portion of the main body 12 so as to be rotatable about a vertical axis. Two ribs 24 are formed on the main body 12 to join the outer periphery of the rotary tube 23, and a fitting groove 25 is formed between these ribs 24. A protrusion 26 formed on the outer periphery of the rotary tube 23 is fitted into the fitting groove 25 . Further, the main body 12 is formed with stoppers 17 and 28, which are brought into contact with the protrusion 26 when the rotary tube 23 is rotated, thereby defining a rotation range of the rotary tube 23.

In such a configuration, when cleaning furniture, a suction hose connected to a dust collecting section of a vacuum cleaner is fitted into the rotary tube 23, and an electric blower (none of which is shown) is driven. Then, the suction air is sucked together with dust from the suction port 13, and these dust and suction air flow into the dust collection section of the vacuum cleaner through the brush chamber 17, the turbine chamber 16, the rotary pipe 23, and the suction hose. At this time, the suction air flowing into the turbine chamber 16 is blown onto the turbine 20 through the vent 22 to rotate the turbine 20, and the rotational force of the turbine 20 is transmitted by the belt 21 to rotate the rotating brush 18.

Then, as shown in FIG. 7, when the main body 12 is moved in the left and right direction for cleaning, the rotary tube 23 is rotatably attached to the main body 12.
The suction port 13 moves parallel to and opposite the surface to be cleaned 29 without increasing the gap with the surface to be cleaned, and the brush bristles 14 move by sweeping the surface to be cleaned. Sweep up 29 and move. Therefore, the suction force is maintained constant without decreasing, and the action of sweeping the surface 29 to be cleaned is increased, so that dust can be effectively sucked over a wide range. When the main body 12 is further moved left and right, the main body 1 is removed by the strippers 27 and 28.
2 is prevented from rotating, the surface to be cleaned 29
The main body 12 is tilted relative to the brush bristles 14 and the surface to be cleaned 29 to form a small gap, and relatively large amounts of dust are also sucked in from this gap. In addition,
The gap between the surface to be cleaned 29 and the brush bristles 14 is such that the main body 12 and the angle β of the left and right swings are ergonomically
In contrast, the rotation angle α of the rotary tube 23 is set within the range of 40° to 50°, so that it does not become large.

Effects of the invention As mentioned above, in this invention, the rotary tube connected to the dust collection part of the vacuum cleaner is rotatably attached to the main body with a vertical axis, so that the main body can be moved from side to side. When cleaning, the suction port can be kept parallel to the surface to be cleaned over a wide range to prevent the main body from floating on the surface to be cleaned, and
Equipped with a rotating brush that sweeps up the surface to be cleaned,
It is possible to promote the action of sweeping the surface to be cleaned without pressing the main body against the surface to be cleaned with strong force, and as a result, when cleaning by moving the main body in the left and right direction, dust can be sucked in well over a wide area. This has the effect of making it possible.
