DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a suction-type cleaning tool, and more particularly to a suction-type cleaning tool for sucking dust and capturing the dust on a fiber sheet.

[0002]

2. Description of the Related Art A vacuum cleaner is well known as a cleaning means for removing dust on a floor surface by suction. However, a general vacuum cleaner has a configuration in which a long suction hose is connected to a cleaner body having a built-in suction fan and a driving motor, and dust is sucked through a suction tool attached to a tip of the suction hose. Although it has the advantage that it can be efficiently cleaned by suction, it is large and heavy as a whole, and hoses and suction tools must be attached and detached each time. It was not suitable for easy use such as cleaning a little when a part was slightly dirty.

[0003]

SUMMARY OF THE INVENTION An object of the present invention is to reduce the size and weight of a general vacuum cleaner and to save the trouble of attaching and detaching a hose and a suction tool. An object of the present invention is to provide a suction-type cleaning tool that can be cleaned at a high speed.

[0004]

According to the present invention, there is provided, in accordance with the present invention, a suction port opening along a generatrix in a part of a cylindrical surface, and a suction fan for sucking outside air from the suction port. An inner cylinder having; a frame fixedly holding the inner cylinder with the suction port facing downward; a handle connected to the frame; rotatably fitted to the outside of the inner cylinder to move the inner cylinder back and forth A porous outer cylinder that rotates by this; a nonwoven fabric sheet for dust capture that is detachably wound around the outer cylinder;
The suction type cleaning tool characterized by having:

[0005] The suction-type cleaning tool having the above-mentioned structure is used by holding the handle in a hand and moving it back and forth on the surface to be cleaned. At this time, the outer cylinder on which the fiber sheet is mounted rotates, but the inner cylinder having the suction port is held in a non-rotating state with the suction port facing downward (to be cleaned). Sucks dust on the surface to be cleaned through the outer cylinder and the fiber sheet. The sucked dust is captured by the fiber sheet in a filtering manner, and is held as it is by the fiber sheet.

[0006] Therefore, the cleaning does not require any trouble of attaching and detaching a long hose or suction tool as in a conventional vacuum cleaner, and can be used immediately as it is. Etc. can be easily cleaned. Moreover, since it is smaller and lighter than a general vacuum cleaner, it is convenient for transportation and storage.

In the present invention, preferably, a seal member for sealing between the inner cylinder and the outer cylinder is attached around the suction port on the outer surface of the inner cylinder. Since the outside air is prevented from being sucked from the lateral direction and the suction force is increased, dust on the surface to be cleaned can be reliably sucked.

[0008] In the present invention, the fiber sheet may be constituted by an outer sheet having a coarse mesh for capturing coarse dust and an inner sheet having a fine mesh for capturing fine dust.

A rectangular frame 2 having a handle 1 for operation, an inner cylinder 3 for suction fixedly attached to the frame 2, and a porous fitting rotatably fitted on the outer surface of the inner cylinder 3. Outer cylinder 4,
Dust capturing fiber sheet 5 wound around the outer cylinder 4
It consists of In the figure, reference numeral 6 denotes a caster for supporting the frame 2 horizontally and movably.
The height is freely adjustable in the corner.

The inner cylinder 3 has a cylindrical shape, and a suction port 10 that opens along a generatrix on a part of the cylindrical surface, and an exhaust port that opens the suction port 10 on the axial side surface of the inner cylinder 3. 11
And a suction fan 12 positioned between the suction port 10 and the exhaust port 11, and the suction port 10 is directed downward on the frame 2 by a mounting shaft 13 that is locked to both end faces in the axial direction. It is fixedly attached in the state. Inside the inner cylinder 3, a small DC motor 15 for rotating the suction fan 12 and a battery 1 serving as a power source of the motor 15 are provided.
6 and a transmission mechanism 17 for connecting the motor 15 and the suction fan 12 are built in. An operation switch 18 for turning on and off the motor 15 is mounted at an appropriate position on the handle 1. Therefore, when the operation switch 18 is turned on, the suction fan 12 is rotated by the motor 15, and the outside air is sucked through the suction port 10.

The outer cylinder 4 has a cylindrical main body 4a made of a porous material such as punched metal or wire mesh.
And cylindrical mounting portions 4b, 4b connected to both ends in the axial direction of the main body portion 4a. On the inner surface of the mounting portion 4b, a guide groove 20 formed on the outer surface of the inner cylinder 3 is slidably fitted. An annular protrusion 21 is formed so as to fit, and is rotatable around the inner cylinder 3 while being supported by the protrusion 21.

A sealing member 2 made of rubber or synthetic resin is provided on the outer surface of the inner cylinder 3 so as to surround the suction port 10.
3 is attached, and the tip of the seal member 23 is
And the inner cylinder 3 and the outer cylinder 4 are sealed by the sealing member 23. This sealing member 23
Is designed to prevent the outside air from being sucked from the lateral direction through the gap between the inner cylinder 3 and the outer cylinder 4 to increase the suction force, and to ensure that the dust on the surface to be cleaned is sucked through the suction port 10. It is for doing.

The fiber sheet 5 wound around the outer cylinder 4 is a non-woven sheet having good air permeability,
The dust sucked from the suction port 10 through the fiber sheet 5 is captured by the fiber in a filtration type. The fiber sheet 5 is always in contact with the cleaning surface during cleaning, and
Is moved back and forth, the outer cylinder 4 is rotated by friction between the fiber sheet 5 and the surface to be cleaned.

When cleaning the surface to be cleaned, such as the floor, with the suction type cleaning tool having the above structure, the handle 1 is held in hand, the operation switch 18 is turned on, and the motor 15 is started. Move slowly back and forth. At this time, the outer cylinder 4 is rotated by the frictional force between the fiber sheet 5 and the surface to be cleaned, but the inner cylinder 3 provided with the suction port 10 keeps the suction port 10 facing downward (to be cleaned). Dust on the surface to be cleaned is sucked from the suction port 10 through the outer cylinder 4 and the fiber sheet 5 while being held in a non-rotating state. Then, the sucked dust is captured by the fiber sheet 5 in a filtering manner, and is held by the fiber sheet 5 as it is.

Therefore, the cleaning does not require any trouble of attaching and detaching a long hose or a suction tool as in a conventional vacuum cleaner, and can be used immediately as it is. Etc. can be easily cleaned. Moreover, since it is smaller and lighter than a general vacuum cleaner, it is convenient for transportation and storage.

If the fiber sheet 5 becomes dirty due to the capture of dust, it is removed from the outer tube 4 and discarded, and a new fiber sheet 5 is attached.

The second embodiment is different from the first embodiment in that the cleaning tool has a uniform eye roughness. The difference is that the fiber sheet 5A is made up of a plurality of inner and outer fiber sheets having different grain sizes, while the number of the fiber sheets 5 is used. That is, the fiber sheet 5A in the second embodiment has a double structure composed of the coarse outer sheet 5a and the fine inner sheet 5b. Captures large and coarse dust,
Dust smaller than that is captured by the fine inner sheet 5b. The configuration of the second embodiment other than the above is substantially the same as that of the first embodiment.

In the above embodiment, the battery 16 is provided in the inner cylinder 3, but it may be built in the handle 1. Further, the fiber sheets 5 and 5A may be impregnated with a dusting agent in order to enhance the adhesion of dust.
