It has excellent sound absorption, flame retardancy, thermal insulation, light weight, convenient secondary processing and other characteristics, and has high water absorption and good corrosion resistance. When used as a cleaning product, its internal open-cell foam structure will absorb stains on the surface of the object during the wiping process, and the cleaning effect is good, so it is widely used in the field of daily cleaning. However, when cleaning, some tubular objects with small inner diameters are often encountered, which are not convenient for direct cutting to obtain large-volume cleaning blocks for cleaning. Utility Model Content

[0006] Furthermore, the thickness of the soft melamine foam layer is 5 mm to 100 mm.

[0007] Furthermore, the thickness of the soft melamine foam layer after being compressed by the water-soluble film layer is 2.5 mm to 80 mm.

[0008] Furthermore, the water-soluble film layer is one of a polyvinyl alcohol water-soluble film and a water-soluble polyimide film.

[0009] Furthermore, the water-soluble film layer has a thickness of 0.03 mm to 0.07 mm.

[0010] Furthermore, the central axis is a stainless steel wire, and the diameter of the central axis is 0.05 mm to 1.0 mm.

[0011] Furthermore, the length of the cleaning tool is 3 cm to 10 m.

[0012] Furthermore, the fixed joint hoop and the water-soluble film layer are made of the same material.

[0013] In summary, due to the adoption of the above technical solution, the beneficial effects of the utility model are:

[0014] 1. Choose soft melamine foam material as the main material of cleaning utensils. It has a foam structure with countless micropores inside. During the cleaning process, it can absorb stains on the surface of objects to the greatest extent, and the cleaning effect is better than other foam materials.

[0015] 2. The cleaning tools are compressed and wrapped into multiple cleaning units made of soft melamine foam layers by fixing the joint hoops. Compared with the existing cleaning tools, the cleaning tools are smaller in size and more suitable for cleaning the inside of various tubular objects with smaller inner diameters. At the same time, the corresponding products of the utility model can be matched according to the length of the tubular objects, which is highly practical.

[0016] 3. Using water-soluble film material, after the cleaning tools are dipped in water, they will dissolve in water, and the thickness of the soft melamine foam will rebound to its original thickness, which can fully contact with the inner wall of the tubular object, with high cleaning efficiency and better cleaning effect.

[0021] All features disclosed in this specification, or steps in all methods or processes disclosed, except mutually exclusive features and / or steps, can be combined in any manner.

[0022] Any feature disclosed in this specification, unless otherwise stated, can be replaced by other equivalent or alternative features with similar purposes. That is, unless otherwise stated, each feature is only an example of a series of equivalent or similar features.

[0023] Example 1

[0024] like Figure 1 , Figure 2As shown, a cleaning brush suitable for tubular objects with a smaller inner diameter comprises a central axis 1, a soft melamine foam layer 2, a water-soluble film layer 3 and a fixed hoops 4, wherein the central axis 1 penetrates the entire soft melamine foam layer 2 and the water-soluble film layer 3 and is fixedly connected to the soft melamine foam layer 2, the water-soluble film layer 3 is wrapped around the outer surface of the soft melamine foam layer 2, and the plurality of fixed hoops 4 are sequentially arranged on the central axis 1, and the fixed hoops 4 are used for pressure restraining the water-soluble film layer 3 and the melamine foam layer 2 so that the water-soluble film layer 3 and the melamine foam layer 2 are combined to form a plurality of cleaning units.

[0025] In the present embodiment, the fixed hoop 4, under the action of the heat shrink film machine, compresses and wraps the soft melamine foam with a water-soluble film, and the thickness of the soft melamine foam layer 2 is compressed to 50%-80% of the original thickness. When in use, a cleaning tool is placed inside the tubular object, and a cleaning tool of appropriate length is cut according to the length of the tubular object. The cleaning tool is then dipped in water, the water-soluble film is dissolved, and the thickness of the soft melamine foam rebounds to its original thickness. The soft melamine foam can fully contact the inner wall of the tubular object, and then the fixed shaft is pulled back and forth to rub the inner wall of the tubular object to clean the stains on the inner wall of the tubular object.

[0026] More specifically, the thickness of the soft melamine foam layer 2 is 5 mm to 100 mm. The selection of this thickness not only achieves the decontamination ability, but also takes into account the convenience of use and the economy of mass production of this product.

[0027] Based on the above design, the thickness of the soft melamine foam layer 2 after being compressed by the water-soluble film layer 3 is 2.5 mm to 80 mm. The fixed hoop 4 compresses and wraps the soft melamine foam layer 2, which is convenient for cutting according to the tubular length of the decontamination object during use, and the operation is convenient.

[0028] As a more specific design, the water-soluble film layer 3 is a water-soluble polyvinyl alcohol film or a water-soluble polyimide film.

[0029] Specifically, the water-soluble film layer 3 has a thickness of 0.03 mm to 0.07 mm. This thickness design is conducive to the cleaning tool being quickly dissolved in water during use, and is conducive to the rebound of the soft melamine foam layer 2, and the cleaning efficiency is high.

[0030] Specifically, the central shaft 1 is a stainless steel wire, and the diameter of the central shaft 1 is 0.05 mm to 1.0 mm. This thickness design is conducive to a more firm connection between the central shaft 1 and the soft melamine foam layer 2, thereby increasing the service life of the cleaning tool.

[0031] As a more specific design, the length of the cleaning brush is 3 cm to 10 m. This length setting can meet the decontamination use in various situations, has wide adaptability and strong practicality.

[0032] On the basis of the above-mentioned design, the plurality of soft melamine foam layer cleaning units, specifically, have fixed hoops at the connections between adjacent soft melamine foam layers 2 .

[0033] Specifically, the fixed hoop 4 and the water-soluble film layer 3 are made of the same material. This design is conducive to the maximum expansion and rebound of the soft melamine foam layer 2, releasing the area, fully contacting with the tubular inner wall of the cleaned object, and increasing the cleaning effect.

[0034] In summary, the utility model is a cleaning tool suitable for tubular objects with a smaller inner diameter, which solves the problem in the prior art that it is inconvenient to clean tubular objects with a smaller inner diameter when using cleaning tools. Soft melamine foam material is selected as the main material of the cleaning tool, and the advantage of its foam structure with countless micropores inside is utilized. During the cleaning process, the stains on the surface of the object can be adsorbed to the greatest extent, and the cleaning effect is better than other foam materials; the water-soluble film layer and the melamine foam layer are combined by fixing the joint hoop to form a plurality of cleaning units, which are smaller in size than the existing cleaning tools, and are more suitable for cleaning the inside of tubular objects with a smaller inner diameter when used. At the same time, the corresponding utility model product can be matched according to the length of the tubular object, and the practicality is strong; the water-soluble film material is used, and after the cleaning tool is dipped in water, it dissolves in water, and the thickness of the soft melamine foam rebounds to the original thickness, which can fully contact with the inner wall of the tubular object, and the cleaning efficiency is high. The utility model is novel in conception, simple in structure, flexible and convenient to use, and has a good cleaning effect.

[0035] The present invention is not limited to the above-mentioned specific implementation modes, but extends to any new features or any new combination disclosed in this specification, as well as any new method or process steps or any new combination disclosed.
