The present disclosure relates to a charging module and a cleaning system, and more particularly to a charging module with a moisture-proof pad and a cleaning system having the same
A self-propelled cleaning device with a wet mopping function is well known and is provided with a liquid storage tank. When the self-propelled cleaning device is charged, it will stand still, and the liquid in the liquid storage tank may leak to the floor, and thus cause the floor to be wet and damaged. CN208973678U discloses a moisture-proof pad for a cleaning device. As shown in
The conventional moisture-proof pad 40 is made of a hard material, is easily deformed, and has the periphery which is not easily attached to the floor. After being deformed, it is hard for the moisture-proof pad to restore, and thus there is a gap between the moisture-proof pad 40 and the floor. Therefore, the side bristles of the cleaning device are easy to insert into the gap, and the dust on the floor is also easy to accumulate in the gap. In addition, when manufacturing the conventional moisture-proof pad 40, it is necessary to attach an anti-skid means 30 to the lower surface of the moisture-proof pad 40, which consumes a lot of time and causes high manufacturing costs.

The following drawings are only intended to schematically illustrate and explain the present disclosure, and do not limit the scope of the present disclosure.
In order to have a clearer understanding of the technical solutions, objects and effects of the present disclosure, specific embodiments of the present disclosure will now be described with reference to the accompanying drawings.
In an embodiment, the charging module 200 further includes at least an adhesive layer 290. In
As shown in
The material of the adhesive sheet is not limited in the present disclosure as long as the moisture-proof pad 220 can be adhered to the surface of the floor. From the perspective of reusability, it is preferred to use a material which can restore at least a part of its viscosity after be washed with water. More preferably, the material of the adhesive sheet includes polyurethane (PU) or silicone. More specifically, polyurethane has the better adhesive recovery after being washed with water, and it can be recycled and reused. As the raw material of the adhesive, polyurethane can be designed to form various molecular structures according to various requirements, and can also be copolymerized and modified with other types of resins, so as to meet the subsequent processing of various materials with different characteristics. Preferably, the material of the adhesive sheet is a polyurethane elastomer (PU elastomer) made of a material containing at least polyurethane. In addition, polyurethane (PU) can be a polymer formed by the reaction of polyol (polyol), isocyanate (isocyanate) and a bond extender (chain extender). The polyols include two types: ethers (polyether) and esters (polyester). The PU synthesized by the ethers (polyether) has water resistance, and the PU synthesized by the esters (polyester) has oil resistance. The application range of PU can be used separately with reference to the comparison of these two characteristics. Examples of the bond extenders include commercially available Lonzacure DETDA (diethyltoluenediamine), Lonzacure M-CDEA, Lonzacure M-DEA, Lonzacure M-DIPA, Lonzacure M-MIPA, and the like.
Preferably, silicone is made of an adhesive material. In an embodiment, the composition of silicone includes raw rubber, silica, silicone oil or silicone oil mixture, a bridging agent and the like. The raw rubber can be natural rubber or synthetic rubber. Commonly used natural rubbers are smoked sheet rubber and standard rubber. Commonly used synthetic rubbers are styrene butadiene rubber, butadiene rubber, and butyl rubber. The raw rubber is mixed with silica to strengthen the structure, the silicone oil mixture is used to produce the required adhesion, the hardness of the main body is changed by the ratio of the components, and the bridging agent is used to promote the combination of the components. The silicone oil mixture includes silicone oil, dimethyl silicone oil, and phenyl silicone oil.
The adhesive sheet is in the form of a sheet. When the adhesive sheet is too thick, the gap will be too large, and the side bristles of the cleaning device 300 will brush the dust into the gap. Further, when the thickness of the pad adhesive sheet is greater than 1mm, the bristles will easily be inserted into the gap and be stuck in the gap, which will affect the moving of the cleaning device. When the adhesive sheet is too thin, it is not easy to fabricate the adhesive sheet. That is, when the adhesive sheet is too thin, it is not easy to use a roller to control the manufacturing process, so when the pad adhesive sheet is too thin, its mass production is not efficient. In addition, when the adhesive sheet is too thin, it is not easy to attach the adhesive sheet to the moisture-proof pad 220. More specifically, it is difficult to control the attachment of the adhesive sheet and requires more time for the attachment of the adhesive sheet. Therefore, preferably, any part of the adhesive sheet has a thickness between 0.1 mm and 1 mm, preferably between 0.2 mm and 0.5 mm. In this embodiment, the thickness of the adhesive sheet is 0.3 mm. When the thicknesses of the first adhesive sheet 211 and the second adhesive sheet 212 are too thick, the gap between the third or fourth side of the moisture-proof pad 220 of the embodiment in
The material of the moisture-proof pad is not limited in the present disclosure, as long as it can reduce the warpage and increase the effect that the moisture-proof pad 220 is smoothly adhered to the surface of the floor. The moisture-proof pad can be a plastic sheet. The moisture-proof pad is made of plastic, such as polycarbonate (PC), polyethylene terephthalate (PET), polypropylene (PP), polyethylene (PE) or polyvinyl chloride (PVC). From the perspective of the adhesion of the moisture-proof pad 220 to the floor, since the adhesion of polyvinyl chloride (PVC) is better than that of plastics such as polypropylene (PP) and polycarbonate (PC), the material of the moisture-proof pad 220 preferably is polyvinyl chloride (PVC).
The method for forming the moisture-proof pad is not limited in the present disclosure, as long as it can increase the effect that the moisture-proof pad 220 smoothly adhered to the surface of the floor. In order to simplify the manufacturing and lower the cost, it is preferable that the moisture-proof pad 220 is cut from a whole substrate (for example, a plastic substrate) to form a cut piece. In an embodiment, preferably, the moisture-proof pad 220 can be made by adhering an adhesive sheet to a substrate (for example, a plastic substrate), and then cutting the substrate (for example, a plastic substrate) to which the adhesive sheet is attached, so that the outer side surface of the adhesive sheet is aligned with one side of the moisture-proof pad 220.
When the thickness of the moisture-proof pad 220 is too thin, the moisture-proof pad 220 cannot fit on the floor flatly. When the thickness of the moisture-proof pad 220 is too thick, the cleaning cloth on the bottom surface of the cleaning device 300 is likely to be stuck, resulting in that the cleaning cloth is skew or fall off, or the moisture-proof pad 220 may easily slide on the floor. In addition, when the thickness of the moisture-proof pad 220 is less than 0.2 mm, the moisture-proof pad 220 will form creases when the moisture-proof pad 220 is torn from the floor, and the moisture-proof pad 220 is no longer flat and has creases. However, when the thickness of the moisture-proof pad 220 is greater than 0.2 mm, the creases can be significantly reduced. Preferably, the moisture-proof pad 220 is sheet-shaped (0.35T), and the thickness of any part of the moisture-proof pad 220 is between 0.2 mm and 5 mm, preferably between 0.2 mm and 1 mm, and more preferably between 0.2 mm and 0.6 mm. In this embodiment, the thickness of the moisture-proof pad 220 is 0.25 mm. In an embodiment, the thickness of the moisture-proof pad 220 can be 0.2 mm, 0.25 mm, 0.3 mm, 0.4 mm, 0.5 mm, 0.6 mm, 0.7 mm, 1 mm, 3 mm, 5 mm, or in a range between any two of the foregoing numbers. PVC has good flatness and wrinkle resistance.
In addition, the cleaning device 300 has a reciprocating brush plate, the cleaning cloth is attached to the reciprocating brush plate, and the thickness of the moisture-proof pad 220 is greater than 5 mm, which results in that the reciprocating movement of the reciprocating brush plate may cause the cleaning cloth to skew or fall off, or the moisture-proof pad 220 slide on the floor. Thus, in this cleaning device, the thickness of the moisture-proof pad is preferably less than or equal to 5 mm. Further, when the thickness of the moisture-proof pad 220 is greater, the more materials are needed to form the moisture-proof pad 220, and the manufacturing cost will be higher. Therefore, preferably, the thickness of the moisture-proof pad 220 is less than or equal to 1 mm, and more preferably less than or equal to 0.6 mm.
