Abstract
Description
Technical Field
[0001] This utility model belongs to the technical field of daily necessities, specifically relating to a mat with self-cleaning function. Background Technology
[0002] The self-cleaning properties mentioned above refer to the ability to repel water and oil. More specifically, the mat will not absorb water and its surface is not easily stained. Once water or stains adhere, they are easily rolled off and / or wiped clean. It ensures that there are no exposed gaps between the mat and the wall, such as the floor or kitchen countertop, thus preventing dust and bacteria from growing or multiplying in the gaps between the mat and the wall. The surface is difficult for dust and dirt to adhere to, and any dirt that appears on the surface can be effectively wiped away, etc.
[0003] The positive benefits of laying relatively thin PVC films on floors, kitchen countertops, etc., can be summarized in the following aspects, not limited to: providing good overall protection for kitchen countertops and floors; convenient cleaning and maintenance; good economic efficiency, environmental cleanliness, and health benefits; flexible application scenarios or wide adaptability, for example, in addition to kitchen countertops and floors, it can also be suitable for laying on surfaces such as tiles and marble; and convenient replaceability.
[0004] As is known, the area where the mat meets the wall is the most susceptible to dust accumulation and bacterial growth. In addition, when wiping the mat, the wiping material, such as a rag or mop, comes into contact with the wall, which can easily cause human-caused pollution to the wall surface, thus damaging the appearance of the wall.
[0005] Therefore, it is of positive significance to explore and develop a mat that can fully reflect the above advantages and avoid the aforementioned shortcomings. The technical solution to be introduced below is generated in this context. Utility Model Content
[0006] The purpose of this invention is to provide a self-cleaning mat that helps to exhibit good hydrophobic and oleophobic effects, facilitates the concealment of gaps at the junction with walls, and enables convenient and quick cleaning.
[0007] The present invention achieves its objective as follows: a self-cleaning mat includes a PVC film body. In its non-use state, the PVC film body is curled up by its own stress with a curling radius of less than 300mm. In its use state, it unfolds into a flat state and is laid out on the surface of a substrate. The key feature is that a long-side weakening line, 10-200mm from the edge and parallel to the edge, is formed on one side of the PVC film body along its length direction, and a wide-side weakening line, 10-200mm from the edge and parallel to the edge, is formed on each side of the PVC film body along its width direction. When the PVC film body is in its unfolded state, one side along its length direction and both sides along its width direction are folded upwards along the long-side weakening line and the wide-side weakening line, respectively, to form a 10-200mm gap that adheres to the wall, thus concealing the gap at the junction between the PVC film body and the wall.
[0008] Furthermore, the long-side weakening line and the wide-side weakening line are formed on the upward-facing side of the PVC film body in the spread state, and the end of the wide-side weakening line facing the long-side weakening line forms a cross-shaped relationship with the long-side weakening line.
[0009] Furthermore, each of the aforementioned long-side weakening lines and wide-side weakening lines has two lines that are both spaced apart from each other and parallel to each other.
[0010] Furthermore, the cross-sectional shape of the long-side weakening line and the wide-side weakening line is V-shaped, C-shaped with a 90° leftward deviation, or an inverted U-shaped.
[0011] Furthermore, the basis weight of the PVC membrane body is 130-1600 g / m³. 2 .
[0012] Furthermore, the substrate can be an interior floor, kitchen countertop, shower room floor, or marble floor.
[0013] Furthermore, the vertical area formed after the weakening lines of the long and wide sides are folded upwards constitutes the stacked edge of the PVC film body 1.
[0014] Furthermore, when multiple sheets of the PVC film body are required during the laying process, the joints between any two adjacent PVC film bodies are seamlessly joined.
[0015] Furthermore, the seamless joint is a high-frequency thermal fusion joint.
[0016] Furthermore, the PVC film body is transparent.
[0017] The technical advantages of the present invention are as follows: Due to the use of a PVC membrane body, it exhibits excellent hydrophobic and oleophobic properties; because the PVC membrane body has long and wide edge weakening lines 10-200mm from the edge on one side of its length direction and on both sides of its width direction, when the PVC membrane body is in its laid-out state, folding it upwards along these weakening lines creates a 10-200mm gap that adheres to the wall, thus concealing the gap between the PVC membrane body and the wall and preventing dust and debris from entering and generating bacteria; and because the PVC membrane body has excellent smoothness with minimal pores, it facilitates convenient and quick cleaning.

[0023] In the diagram: 1. PVC membrane body, 11. Long side weakening line, 12. Wide side weakening line, 13. Stacked edge; 2. Floor; 3. Wall. Detailed Implementation
[0024] Example 1: Please refer to Figures 1 to 3 The image shows a PVC membrane body 1, which is curled up under its own stress in a non-use state with a curling radius of less than 300 mm, and unfolded into a planar state in a spread (also known as "laying") state and is laid on the surface of the substrate.
[0025] The key technical points of the technical solution provided by this utility model are as follows: On one side of the length direction of the aforementioned PVC membrane body 1, a long side weakening line 11 is formed at a position preferably 10-200mm from the edge, more preferably 50-150mm, and most preferably 100mm (100mm is selected in this embodiment) and parallel to the aforementioned edge; and on both sides of the width direction of the PVC membrane body 1, a wide side weakening line 12 is formed at a position preferably 10-200mm from the edge, more preferably 50-150mm, and most preferably 100mm (100mm is selected in this embodiment) and parallel to the aforementioned edge. When the aforementioned PVC membrane body 1 is laid on the floor 2, one side of the length direction and both sides of the width direction of the PVC membrane body 1 are folded upward along the aforementioned long side weakening line 11 and wide side weakening line 12 respectively to form a 100mm gap that is close to the wall 3, thereby concealing the gap at the junction between the PVC membrane body 1 and the wall 3.
[0026] The aforementioned long-side weakening line 11 and wide-side weakening line 12 are arranged on the upward side of the PVC film body 1 in its laid-out state, and the portion of the wide-side weakening line 12 facing one end of the long-side weakening line 11 forms a cross-shaped relationship with the long-side weakening line 11. Figure 1 Show).
[0027] In this embodiment, the aforementioned long-side weakening line 11 and wide-side weakening line 12 each have two lines that are both spaced apart from each other and parallel to each other.
[0028] The cross-sectional shape of the aforementioned long-side weakening line 11 and wide-side weakening line 12 is an inverted U-shape, that is, it tends to be U-shaped.
[0029] The concept of the upward-facing side of the PVC film body 1 in its unfolded state refers to the side facing away from the supporting carrier, such as the aforementioned floor 2. The aforementioned long-side weakening line 11 and wide-side weakening line 12 are formed during processing through thermal pre-forming or other similar methods. Thermal pre-forming involves creating a structural crease on the aforementioned PVC film body 1 using a heating process, thereby forming regular weakening lines whose mechanical strength is intentionally reduced. The aforementioned long and wide-side weakening lines 11 and 12 can also be referred to as long and wide-side indentations or grooves.
[0030] The basis weight of the aforementioned PVC membrane body 1 is 130-1600 g / m³. 2 A better value is 500-1200g / m³. 2 Better 600-800g / m 2 Ideally, it should be 700g / m 2 (This example uses 700g / m³) 2 ).
[0031] In addition to the aforementioned floor 2 inside the building, the aforementioned substrate can also be a kitchen stove, a shower room floor, or a marble floor, etc.
[0032] When the aforementioned long and wide weakening lines 11 and 12 are folded upwards, the vertical area formed constitutes the stacked edge 13 of the PVC film body 1, which can also be called a wall skirt.
[0033] When multiple PVC film bodies 1 are used during the installation process, the joints between any two adjacent PVC film bodies 1 are seamless. The aforementioned seamless joint is a high-frequency heat-fusion joint.
[0034] In this embodiment, the aforementioned PVC film body 1 is transparent.
[0035] The width of the PVC film body 1 of this utility model can be 600mm, 800mm, 1000mm or 1200mm, etc., and there is no need to limit it in this embodiment.
[0036] Example 2: Please refer to Figure 4 In this embodiment 2, the long side weakening line 11 is changed to a V-shaped cross-section, and the corresponding wide side weakening line 12 ( Figure 4 The cross-sectional shape (not shown) is also V-shaped. Everything else is the same as described in Example 1.
[0037] The applicant should note that, in addition to embodiments 1 and 2, the cross-sectional shapes of the long and wide weakening lines 11 and 12 can also be a C-shape or other similar cross-sectional shapes that are deflected 90° to the left.
[0038] Application example: Please refer to Figure 5 , Figure 5 The illustration shows the structure of Embodiment 1 laid on the floor 2, and the 100mm range facing the wall 3 is in contact with the wall 3. Due to the presence of the long side weakening line 11 and the wide side weakening line 12, the folded part forms a stacked edge 13 with a wainscoting effect, so that external dust and debris will not invade the gap between the PVC film body 1 and the wall 3.
[0039] Since the application of the structure in Example 2 is the same as that in Example 1, it will not be described again.
[0040] Of course, this utility model can also be applied to other occasions besides kitchen stoves, shower rooms, and marble floors mentioned above.
