ものがある。[Prior Art] In the rotary brush of a conventional suction cleaner, there is a device that prevents thread waste from becoming entangled or wrapped around the brush, as disclosed in Japanese Patent Publication No. 63-35246, which was previously filed by the applicant of the present application. .

実に収納することができた。The rotating brush shown in the above publication has a plurality of flexible blades on the outer periphery of a rotating shaft, each of which has a number of protrusions protruding from the contact surface with the surface to be cleaned, and is arranged so as to spread radially from each other. It is erected in a spiral shape in the axial direction. In the above-mentioned rotating brush, the individual protrusions of the blade play the same role as the tips of the individual bristles of the brush, effectively scraping up thread waste stuck to each carpet, and moreover, removing these thread waste. The suction power of the vacuum cleaner's suction device made it possible to securely store it in the dust box without getting it tangled with the blade.

糸ゴミの巻き付き、絡み付きを防ぐことはできても、長
い糸ゴミ（実験では、回転ブラシの外周の長さの３倍を

であった。(Problems to be Solved by the Invention) Although the above-mentioned rotating brush can prevent cotton waste and relatively short thread waste from getting entangled, long thread waste (in experiments, it has been found that It has been difficult to prevent thread waste (with a length exceeding three times the length of the outer circumference) from wrapping around the thread.

ゴミ５３は吸引ダクト５４に吸引される。The cause of this will be explained based on the drawings. In the case of short thread waste, as shown in FIG. 10(a), since the protrusion 52 of the blade of the rotating brush 50 faces the direction of rotation of the blade 51, the thread waste 53 caught on the protrusion 52 will be removed.
The reason is that the protrusion 52 is difficult to come off. Nevertheless, since the thread waste is short, the thread waste 53 is sucked into the suction duct 54 when brought above the suction tool by the rotation of the blade 51, as shown in FIG. 10(b).

させることになる。As shown in (2) and (C), when the tip of the thread waste 53 caught on the protrusion 52 of the blade is carried in the rotational direction as the blade 5I rotates, the rear part of the thread waste 53 becomes the carpet 6.
Since the thread waste 53 acts to be pulled relatively from the rear due to the frictional resistance with the thread thread 53, the tip end of the thread waste 53 is firmly locked to the protrusion 52 and becomes difficult to come off from the protrusion 52. In particular, when the thread waste is extremely long, for example, if the thread waste is longer than three times the length of the outer circumference of the rotating brush, the thread waste is always pulled from the rear due to the frictional resistance between the thread waste and the carpet. As a result, the thread waste that has one end caught on the protrusion of the blade will be caught up in the rotating brush with the end firmly caught on the protrusion, and eventually the entire thread waste will be wrapped tightly around the rotating brush. become. Furthermore, the thread waste wrapped around the rotating brush moves along the spiral direction in which the blades are arranged to the end of the rotating shaft due to the frictional resistance of the floor surface against the thread waste, and finally becomes entangled with the rotating shaft, causing malfunction of the rotating brush. or cause rotation to stop.

び掻きあげられ、遂には吸込ダクト６に吸い込まれる。The rotary cleaning body 3 is a cylindrical body made of hard nylon, light alloy, etc. with good lubricity and wear resistance, and has a row of protrusions 9 containing numerous protrusions 9a protruding radially from the axis on the circumferential surface.
is formed. Although the protrusions can be provided protruding over the entire outer peripheral surface of the cylindrical body, it is advantageous to form a plurality of protrusion rows in order to reduce the sliding resistance of the rotary cleaning body against the floor surface. . Since the protrusions 9a protrude radially from the axis on the outer peripheral surface of the rotary cleaning body 3, if the protrusions are made of a material with good slipperiness such as hard nylon, as shown in FIG. As shown in , the tip of the thread waste 15 caught on the protrusion 9a is pulled relatively backward due to the frictional resistance of the thread waste on the part of the carpet 116 that is in pressure contact with the rotating cleaning body 3. It easily comes off from the protrusion 9a and does not wrap around the rotary cleaning body 3. However, if the protrusions are made of a material with poor slipperiness such as rubber, it will be difficult for thread waste to come off the protrusions, so as shown in FIG. A protrusion 10 higher than the height of the protrusion 9a is arranged parallel to the protrusion group row 9. With this configuration, even if the protrusions are made of a material with poor slipperiness such as rubber, thread waste 15 caught on the protrusions 9a can be removed from the protrusions 15 that are higher than the protrusions 9a at the rear of the protrusion group row 9.
Since the thread waste is pulled from the top of the thread o, that is, from diagonally above the protrusion 9a, the thread waste is pulled against the slope of the protrusion on which the thread waste is caught, and the angle width of the thread becomes small, and the thread waste is easily removed from the protrusion. The height of the protrusion may be equal to or lower than the protrusion group row depending on the distance from the protrusion group row or the formation pitch of the protrusion group row. In this way,
The tip of the thread waste 15 that has come off the protrusion 9a is shown in Figure 3 (b).
), it is scraped up again by the next row of protrusions 9 coming from the rear, and finally sucked into the suction duct 6.

した構成にすることもできる。In this embodiment, a rotary cleaning body in which a row of protrusions is formed on the outer circumferential surface of a cylindrical body made of hard nylon or a light alloy has been described. In order to be compatible with carpets, a flexible foam 8 is wound around the rotating shaft 2 as shown in FIG. It is also possible to have a structure in which the rubber-like elastic body 7 is covered with a sheet.

ことができる。As shown in FIG. 5, both ends of the rotary cleaning body 3 are formed into a substantially truncated cone shape whose diameter decreases toward the outside in the axial direction, and the inclined parts 11 at both ends of the shaft are in contact with the floor surface. This prevents thread waste from being scraped up at the end of the shaft, further improving the effect of preventing thread waste from being wrapped around the bearing.

In order to improve the operability of the suction head, as shown in FIG. 7, the diameter R2 of the portion 21 of the rotating outer peripheral surface where the protrusion group row 9 is not formed is changed to the portion 22 where the protrusion group row 9 is formed. The diameter R can also be made smaller.

A part 32 which is bent in the opposite direction to the rotational direction to form an abbreviated shape, and which rubs against the floor surface at the tip of this protrusion band 31.
It is also possible to have a configuration in which countless projections (rows of projection groups) 33 are formed. In this case as well, since the protrusions protrude in the radial direction from the axis of the rotating body, as in the case of the cylindrical rotating body, winding and entanglement of thread waste can be effectively prevented.

り、極めて高い吸塵力を示す。By using the rotating cleaning body according to the present invention, it is possible to effectively scrape off thread waste stuck on the carpet, and no matter how long the thread waste is, it does not get wrapped around the rotating cleaning body and can be immediately removed. Since the rotating cleaning body is sucked by the rotating shaft, there is no winding around the shaft end of the rotating shaft, and maintenance of the rotating cleaning body is completely unnecessary, and cleaning work is not interrupted, so cleaning efficiency is improved. In addition, if the rotary cleaning body according to the present invention uses a cylindrical body as the rotary body, the air resistance experienced during rotation is extremely small compared to a blade brush, and turbulence does not occur in the suction port, so there is no operational noise. There is also the advantage that the cylindrical rotating cleaning body is in close contact with the surface to be cleaned at the suction port, so the area of the opening at the suction port is small (as a result, The flow rate of the intake air flow at the suction port has increased significantly, and even when picking up fine dust such as sand and dirt, the amount of scraping of the villi by the group of protrusions is not only effective, but also extremely high due to the strong suction force from the suction port. Indicates dust suction power.
