Detailed Description of the Invention

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a cleaning tool which is used by applying a cleaning agent or the like on a surface thereof and is used for removing dirt such as water spots adhering to the cleaning surface. The present invention relates to a cleaning tool that is used by being pressed against a cleaning surface while being rotated around an axis of rotation that is approximately perpendicular to the cleaning surface in a state where the cleaning agent is applied.

2. Description of the Related Art Conventionally, a sponge or the like has been known as a cleaning tool of this kind. For example, when cleaning oil, dust, water spots, etc. adhering to the glass surface, a cleaning agent is attached to the sponge surface, Cleaning is performed by pressing on the glass surface and sliding on the surface.

[0003]

However, when a sponge or the like is used, there is no big problem if the area to be cleaned is small, but if this area becomes large, the cleaning agent scatters in the outer peripheral direction of the sponge. There is a problem that it is difficult to retain the sponge. Furthermore, in cleaning,
It is necessary to foam the cleaning agent, but since the bubbles contained in the sponge are small, the pressure fluctuation due to the bubble formation is small, and it is difficult to generate a large number of bubbles on the sponge surface layer that greatly affects the cleaning effect. is there. The purpose of the present invention is to
The purpose of the present invention is to obtain a cleaning tool capable of retaining the cleaning agent in the cleaning tool for a long time, and sufficiently foaming the cleaning agent on the surface of the cleaning tool that performs the cleaning action to obtain an efficient cleaning effect. .

[0004]

Means for Solving the Problems A feature of the present invention for achieving the above object is to provide an air permeable porous membrane layer on the surface in contact with a cleaning surface and to provide a non-air permeable material on the back surface side of the air permeable porous membrane layer. A support member layer made of a flexible elastic material, and a bottomed recessed space that opens to the front surface side is provided at the surface-side end surface of the support member layer in the vicinity of the axis of rotation of the support member layer. Yes, its actions and effects are as follows.

[0005]

[Operation] When cleaning with this cleaning tool,
The cleaning tool is used while rotating around the axis of rotation, and during such cleaning operation, in this cleaning tool, from the recessed space provided in the support member layer to the external space through the breathable porous membrane layer. An air flow path is formed between and. The non-breathable support member layer and the cleaning surface form the interface of this flow passage. Then, in the state in which the cleaning tool is used, breathing of air (inflow and outflow between the recessed space of the air and the external space) occurs through this flow passage. Therefore, the cleaning agent applied to the cleaning tool is sufficiently foamed in the breathable porous membrane layer to exert its cleaning performance, and a certain amount of the cleaning agent is retained in the recessed space. Further, the breathing facilitates the retention in the breathable porous membrane layer, and as a result, it becomes possible to proceed the cleaning operation for a relatively long time even when the cleaning agent is not replenished. The function described above is more efficiently exhibited by forming the supporting member layer with an elastic material.

[0006]

Therefore, the cleaning agent can be retained in the cleaning tool for a long time, and the cleaning agent can be sufficiently bubbled on the surface of the cleaning tool that performs the cleaning action to obtain an efficient cleaning effect. A cleaning tool can be obtained, and for example, a cleaning tool that can be used for cleaning a large area glass surface of a vehicle, a building, etc., or a stainless steel surface can be obtained. Furthermore, the cleaning of water spots generated on the glass surface, stainless steel surface, etc. has been conventionally classified into a relatively difficult part to be cleaned, but the cleaning tool of the present application makes it easy to clean it. It was

The support member layer 3 is made of metal and the plate-like body 5 having the velcro tape layer 4 on the back surface provided on the lower side of the support member layer 3 is provided. Then, as shown in the figure, a configuration is adopted in which the velcro tape layer 4 described above is used by being attached to a rotating device 6 equipped with a motor (not shown) and the like. Here, the support member layer 3 includes the rotating device 6 as described above.

a and the surface side opening 30 of the hollow cylindrical portion as the recessed space 3b
It is formed as a disk-shaped film that covers the entire surface. Further, since the supporting member layer 3 is provided with the above-mentioned plate-like body 5 on the back surface (the lowermost surface in the drawing), the recessed space 3b is a closed space with a bottom that opens to the side of the breathable porous membrane layer 2. In the cleaning operation state, it is sandwiched between the cleaning surface 7 and the support member layer 3 and is connected to the atmosphere side through the air flow passage through the air permeable porous membrane layer 2.

The worker attaches the cleaning tool 1 to the rotating device 6 side (which is provided with a magic tape layer 6a paired with the magic tape layer 4 on the cleaning tool side) 6 side with the magic tape layer 4 for use. In cleaning, the cleaning agent is applied to the surface of the cleaning agent or the surface to be cleaned. The operator uses the pivot body of the rotating device 6 while supporting it with a hand or the like. Then, a sufficient foaming function and a cleaning agent holding function can be exhibited to clean a large area of the cleaning surface.

[Other Example] In the above example, the most effective example was described for the water spot formed on the glass surface that is the most difficult to clean.

(D) In the above embodiment, the cleaning tool is formed in a cylindrical shape, but the shape is not limited to this. (E) Further, both the breathable porous membrane layer and the supporting member layer are formed in a plate shape having a uniform thickness in the circumferential direction, but may be formed in a corrugated shape in relation to the foaming performance. Further, it may be formed in a corrugated shape in the circumferential direction, and the top of the corrugated wave described above may be formed in a spiral shape like a fan blade in relation to the rotating operation direction of the cleaning tool. In this case, it is necessary to form a spiral in a direction in which the cleaning agent can be easily held, and the spiral is wound in a reverse direction to a general fan.
